Description

CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the priority of the Chinese patent application with the application number of 202422654287.1, filed with the CNIPA on Oct. 31, 2024 and entitled “Engine compartment structure, skid steer loader and engineering equipment”, which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application relates to the technical field of engineering machinery, in particular relates to an engine compartment structure, a skid steer loader and an engineering equipment.

BACKGROUND

For some small-scale engineering machinery and equipment, due to their compact structure and narrow space for component arrangement, there are often situations where the operating space is restricted. Taking a skid steer loader as an example, it is a kind of small and flexible engineering machinery, which is suitable for occasions of narrow operating site, uneven ground, and frequent change of operation tasks. In order to improve the overall performance and comfort of a skid steer loader and reduce noise, an independent cooling system is usually used to match its power system.

However, due to the compact structure of a skid steer loader and the narrow space for component arrangement, equipment components inside the skid steer loader, such as a radiator, need to be arranged in the upper part of an engine compartment, wherein an engine compartment hood is arranged above the radiator, and a heat dissipation motor is arranged below the radiator. If an upper hood of the engine compartment hood is configured as an openable structure, although it is convenient to conduct inspection of the appearance of the radiator or add antifreeze thereto and other operations, however, when the heat dissipation motor and other components inside the engine compartment need inspection and repair, it is necessary to detach the radiator, which results in relatively poor convenience for maintenance and repair of the entire machine.

In order to make purposes, technical solutions and advantages of the embodiments of the present application clearer, technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings described in the embodiments of the present application. Apparently, the described embodiments represent a part of the embodiments of the present application, not all of them. Based on the embodiments described in the present application, all other embodiments obtainable by those ordinarily skilled in the art without expenditure of creative labor fall within the scope of protection of the present application.

The embodiments of the present application are described in conjunction with FIGS. 1 to 13.

The embodiments according to the present application, in one aspect, provide an engine compartment structure that includes:

• • a housing 2, including a first housing part 201 and a second housing part 202;
  • a component 4, arranged on a side of the first housing part 201 towards an interior of the housing 2 and movably connected with the first housing part 201, wherein at least one of the first housing part 201 and the component 4 is movably connected with the second housing part 202;
  • wherein the first housing part 201 has a first state of being independently rotatable relative to the component 4 and a second state of being rotatable together with the component 4 relative to the second housing part 202.

In the engine compartment structure provided by the present embodiment, the component 4 is movably connected with the first housing part 201, so as to enable the first housing part 201 to be independently movable relative to the component 4, thereby facilitating maintenance and repair of the component 4 alone. And the first housing part 201 and/or the component 4 is movably connected with the second housing part 202, so as to also enable the first housing part 201 to be movable together with the component 4 relative to the second housing part 202, thereby making way for the maintenance and repair of other equipment parts inside the housing 2.

Specifically, an accommodating cavity is provided inside the housing 2 to accommodate equipment parts such as an engine and the component 4, and the second housing part 202 mainly has a function of supporting and bearing forces for the first housing part 201 and equipment parts such as the component 4, and the second housing part 202 may be a part of the engine compartment, or may be a part of the equipment main body, for example, it is a support beam extending from the equipment main body. Optionally, the second housing part 202 may be a fixed structure, or may also be a movable structure capable of moving relative to the equipment main body.

The component 4 may be a component such as a radiator, a heat exchange plate, a reservoir, and the like. In this embodiment, the component 4 can specifically be a radiator. The first housing part 201 can be independently rotatable in a direction away from the radiator to expose the radiator, thereby facilitating operations such as inspecting the appearance of the radiator or adding antifreeze thereto. The first housing part 201 and the radiator can also form an integral structure that is rotatable in a direction away from the interior of the housing 2 to expose the interior of the housing 2, so that it makes way for other equipment parts located inside the housing 2 for maintenance and repair, without detaching the radiator.

The integral structure formed by the first housing part 201 and the component 4 may be connected with the second housing part 202 in three ways, that is,

• • the first housing part 201 is movably connected with the second housing part 202 to realize that the integral structure formed by the first housing part 201 and the component 4 is rotatable relative to the second housing part 202;
  • the component 4 is movably connected with the second housing part 202 to realize that the integral structure formed by the first housing part 201 and the component 4 is rotatable relative to the second housing part 202;
  • the first housing part 201 and the component 4 are respectively connected with the second housing part 202 to realize that the integral structure formed by the first housing part 201 and the component 4 is rotatable relative to the second housing part 202.

A handle 17 is fixedly connected to the component 4 and/or the first housing part 201, so that an operator can drive the component 4 and/or the first housing part 201 to move relative to the second housing part 202 by means of the handle 17.

In one embodiment, as shown in conjunction with FIGS. 1 to 13, the component 4 is hinged to the second housing part 202 by means of a second hinge structure 8, and the first housing part 201 is hinged to the component 4 by means of a first hinge structure 7.

Specifically, forms of the above-mentioned movable connection may include: a rotatable connection, a slidable connection, an elastic connection or a magnetic connection, and the like. Further, the rotatable connection may include: a hinged connection, a ball joint connection, a universal joint connection, a gear connection, and the like; and a multi-link structure connection or a worm gear connection, and the like, may be further adopted, This embodiment takes the use of hinged connection as an example to specify the movable connection modes of the present application.

As a feasible form of implementation, the second hinge structure 8 is configured as a hinge with two rotating portions that are fixedly connected with the component 4 and fixedly connected with the second housing part 202 respectively by means of bolts and washers.

In some embodiments not shown, the second hinge structure 8 may also be configured in the structural form of a pin shaft and pin hole, a ball joint connecting rod and a ball hinge seat, an articulation, etc., as long as the hinged connection between the component 4 and the second housing part 202 can be achieved.

The first hinge structure 7 can refer to the above-mentioned structural forms of the second hinge structure 8. Specifically, the first hinge structure 7 can adopt the same structural form as the second hinge structure 8, or may also adopt a structural form different therefrom.

Among them, the number of the second hinge structure 8 and the number of the first hinge structure 7 are both at least one.

Additionally, a crossbeam 3 is fixedly connected to the second housing part 202, the second hinge structure 8 is connected with the crossbeam 3 and connected with the component 4 respectively.

As an option, a hinge axis of the second hinge structure 8 is in coincidence with a hinge axis of the first hinge structure 7.

In one embodiment, as shown in conjunction with FIGS. 1 to 13, the engine compartment structure further includes a locking structure, the locking structure has a locked state in which a relative position between the component 4 and the second housing part 202 is locked, and an unlocked state in which the component 4 is allowed to rotate relative to the second housing part 202.

In the engine compartment structure provided by the present embodiment, when there is no need to inspect and repair equipment parts inside the housing 2, the locking structure is arranged to ensure the overall stability of the component 4 and the second housing part 202, as well as the operability of opening the first housing part 201 alone.

Specifically, when the locking structure is in the locked state, the relative position between the component 4 and the second housing part 202 is fixed, which is conducive to reducing the shaking and noise during the operation of the equipment, and at this time, when the first housing part 201 is rotated, the component 4 will not be rotated along with it, which is convenient for allowing the first housing part 201 to be independently turned over.

In one embodiment, as shown in conjunction with FIGS. 1 to 13, the locking structure includes a locking body 14 and a locking column 6, one of the locking body 14 and the locking column 6 is connected to the component 4, and the other of the locking body 14 and the locking column 6 is connected to the second housing part 202, the locking body 14 is detachably connected to the locking column 6.

Specifically, the locking body 14 is fixedly connected to the component 4 or fixedly connected to the second housing part 202 by means of screws 5, and in the process of the component 4 being rotated from a position of being exposed out of the housing 2 to a position of being inside the housing 2, the locking column 6 gradually approaches the locking body 14 until the locking column 6 collides with a lock tongue of the locking body 14 and engages with it, thereby realizing the fixing of the relative position between the component 4 and the second housing part 202. It should be noted that the way of engagement and locking, as well as the way of unlocking, between the locking body 14 and the locking column 6 belong to the prior art (e.g., the locking structure disclosed in the patent application with the Publication number of CN102587747A, which is incorporated in the present application by reference in its entirety), and therefore the specific structure and working principle thereof will not be discussed in detail.

In the engine compartment structure provided by the present embodiment, the first supporter 9 is arranged to support the integral structure formed by the component 4 and the first housing part 201 after it is turned over and opened, thereby facilitating inspection and repair of other equipment parts inside the housing 2.

Specifically, the first supporter 9 is configured as a gas spring, one end of the gas spring is hinged to the equipment main body by means of a hinge seat 16, and the other end of the gas spring is hinged to the component 4 or the first housing part 201 by means of another hinge seat 16, so as to support the above-mentioned integral structure when the integral structure formed by the component 4 and the first housing part 201 is rotated to the position of being exposed out of the housing 2. When the first supporter 9 is hinged to the first housing part 201, the first housing part 201 and the component 4 are in a detachable fixed connection with each other, and the forms of detachable connection include a bolt connection, a quick-release pin connection, and the like, or the above-mentioned locking structure may also be utilized to achieve the detachable connection.

In some embodiments not shown, the first supporter 9 may also be configured as a telescopic rod. The telescopic rod includes multiple standard sections that can extend and retract relative to each other. Every two adjacent standard sections can be locked or unlocked by means of a lockable structure to prevent the telescopic rod from retracting accidentally. The lockable structure may include a threaded lockable structure, a spring-loaded lockable structure, etc. It should be noted that the locking and unlocking of a telescopic rod is an existing mature technology, therefore, its specific structure and working principle will not be elaborated herein. The first supporter 9 may also be selected from an electric cylinder, a hydraulic cylinder, a pneumatic cylinder, etc., to provide a driving force for rotating the integral structure formed by the component 4 and the first housing part 201, thereby facilitating the operation of an operator.

In one embodiment, as shown in conjunction with FIGS. 1 to 13, the engine compartment structure further includes at least one second supporter 10, one end of the second supporter 10 is connected to the first housing part 201, and the other end of the second supporter 10 is connected to the component 4, so as to enable the first housing part 201 and the component 4 to be arranged at an angle relative to each other.

A local area of a side wall of the sliding groove 19 is dented to form a position limiting groove 191, and the number of the position limiting 191 may be one or may also be multiple which are arranged at intervals along the length of the sliding groove 19. During a process of the first housing part 201 being rotated relative to the component 4, one bending portion of the fixing rod can be snap-fitted into the position limiting groove 191 to fix a relative position of the first housing part 201 relative to the component 4. When a plurality of position limiting grooves 191 are provided, the bending portion can be snap-fitted into different position limiting grooves 191 so as to keep the first housing part 201 and the component 4 at different angles relative to each other.

As an additional form of implementation, one end of the fixing rod is hinged to one of the component 4 and the first housing part 201, and the other end of the fixing rod abuts against the other of the component 4 and the first housing part 201.

Specifically, the plugging element 13 is arranged in a full circumference along the edge area of the contact surface between the component 4 and the first housing part 201. The plugging element 13 may include a sponge pad, a rubber pad, etc. When the number of the plugging element 13 is one, the plugging element 13 is connected to the first housing part 201 or the component 4. When the number of the plugging element 13 is multiple, plugging elements 13 are connected to the first housing part 201 and/or the component 4.
