FOLDING UMBRELLA STRUCTURE

Description

TECHNICAL FIELD

The present invention relates to the technical field of sunshade structures, in particular to a folding umbrella structure.

BACKGROUND

Sunshades are mainly used outdoors to provide shade. However, most of the umbrella ribs of current sunshades cannot be folded, such as the sunshade as disclosed in Chinese invention patent publication No. CN116138557A, resulting in relatively long length of the sunshade after being folded, making it inconvenient to carry when going out and also causing a large packaging volume. Therefore, to address the above problems, a sunshade structure with foldable ribs was developed, as shown in Chinese invention patent publication No. CN209518401U. Although the folding umbrella structure can be folded, the top center of the umbrella is too flat after being opened. This makes the sunshade less aesthetically pleasing, and the middle of the umbrella fabric sags when the sunshade is fully opened. When it rains, water will continuously accumulate in the sag, increasing the weight of the umbrella and potentially causing uneven distribution. This may compromise stability of the folding umbrella when in use, especially when used as a large sunshade, which poses a risk of tipping over. Therefore, improvements are urgently needed.

SUMMARY

An object of the present invention is to provide a folding umbrella structure to address the above-mentioned technical deficiencies.

The folding umbrella structure provided by the present invention includes: a fixing component; a first movable component slidably mounted on the fixing component so that the first movable component is displaceable along a length direction of the fixing component; a second movable component provided coaxially with the fixing component and located at an end portion of the fixing component; and a plurality of folding members provided in a circumferential distribution along an outer periphery of the fixing component, wherein a first connecting end, a second connecting end, and a third connecting end of each of the folding members are hinged with the first movable component, the second movable component, and the end portion of the fixing component respectively, so that each of the folding members has a first state when unfolded or a second state when folded; in the first state, a distance between the first movable component and an end face of the fixing component is L1, a distance between the second movable component and the end face of the fixing component is L2, and each of the folding members forms a tilt support portion, and an included angle between the tilt support portion and an axis of the fixing component is an acute angle; and in the second state, a distance between the first movable component and the end face of the fixing component is L3, the second movable component is close to the end face of the fixing component, L3>L1, L3>L2, and each of the folding members is disposed in an axial direction of the fixing component.

In another aspect, a folding umbrella structure includes: a fixing component; a first movable component provided coaxially with the fixing component and located below the fixing component; and a plurality of folding members provided in a circumferential distribution along an outer periphery of the fixing component, where a first connecting end and a second connecting end of each of the folding members are hinged with the first movable component and the fixing component respectively, so that each of the folding members has a first state when unfolded or a second state when folded; in the first state, a distance between the first movable component and the fixing component is L1, and each of the folding members forms a tilt support portion, and an included angle between the tilt support portion and an axis of the fixing component is an acute angle; and in the second state, a distance between the first movable component and an end face of the fixing component is L3, L3>L1, and each of the folding members is disposed in an axial direction of the fixing component.

The folding umbrella structure provided by the present invention has the following beneficial effects:

• • 1. Adding a fifth connecting rod to each of the folding members and providing the second movable component enable an umbrella fabric to have a conical structure after umbrella ribs are opened, creating an inclined surface from the apex at the center to the edge of the umbrella fabric. This design enhances the aesthetic appeal of the folding umbrella. During rainfall, water flows downward along the inclined surface, preventing accumulation.
  • 2. Providing a first steering knuckle, a second steering knuckle and a locking structure allows a pole body to be bent, so that an orientation angle of an opened umbrella is adjusted, and the umbrella is locked by the locking structure after adjustment, which allows to adapt to sunshading in different orientations.
  • 3. Providing light emitting device on a first connecting rod and a fourth connecting rod and powering the light emitting devices by a solar cell box make outdoor power supply more convenient, so that when used at night, the light emitting devices can provide illumination after being powered on.
  • 4. The two folding umbrella structures, when folded in a large sunshade, result in a reduced sunshade volume, facilitating packaging and storage. Additionally, the packaging volume is also reduced, which is convenient for carryover, and reduces the cost of bulk transportation for manufacturer during shipment.
