DETAILED DESCRIPTION

Referring to FIGS. 1-11, aspects of the present disclosure provide a mobile workstation 100, for example, a production cart commonly used in the photography field.

In some aspects, referring to FIGS. 1-2, the mobile workstation 100 can include an extension platform 1 and a connecting frame 5. One end of the connecting frame 5 is connected to the extension platform 1, and the other end is equipped with a mounting member 2 capable of connecting to the mobile workstation 100.

The extension platform 1 can be installed on a production cart via the mounting member 2 and the connecting frame 5. The extension platform 1 has a table module 3 that can enhance the functionality of the production cart, thereby addressing the issue of limited functionality.

In some aspects, the mounting member 2 can be a pipe clamp or other common clamps available on the market, capable of being clamped and fixed to a column 101 of the production cart, facilitating the installation and removal of the mobile workstation 100.

In some aspects, the extension platform 1 has one or more extension positions 4. The extension position 4 can adopt standard table extension interfaces such as an extension slot 41 or an extension hole 42. Different functional table modules 3 can be installed, such as a tabletop 31, table hooks, outdoor stoves, cutting boards, storage racks, refrigerators, or coolers—standard modules of the table module 3.

In some aspects, the extension platform 1 is formed by enclosing and splicing several plates. An extension slot 41 is formed between the plates for installing the tabletop 31, and extension holes 42 can be provided on the plates for installing table hooks.

In some aspects, the mobile workstation 100 can include a connecting frame 5 capable of driving the extension platform 1 to move relative to the mounting member 2. One end of the connecting frame 5 is connected to the extension platform 1, and the other end is connected to the mounting member 2. The connecting frame 5 can drive the extension platform 1 to rotate, enabling folding or unfolding of the extension platform 1. During use, the extension platform 1 is unfolded and supported by the connecting frame 5; when not in use, the extension platform 1 can be folded and stored to one side of the production cart by rotation, saving occupied space.

In some aspects, the connecting frame 5 can include a connecting member 51, a support member 52, and a locking assembly 53. One end of the connecting member 51 is fixedly connected to the mounting member 2, and the other end is movably connected to the extension platform 1. One end of the support member 52 is movably connected to the connecting member 51, and the other end is connected to the extension platform 1 via the locking assembly 53, enabling the extension platform 1 to be folded and unfolded relative to the mounting member 2.

In some aspects, the connecting member 51 and the support member 52 are both rod-shaped structures. Both ends of the connecting member 51 are equipped with rotating shafts. The bottom of the extension platform 1 is provided with a rotating base, and the extension platform 1 is rotatably connected to the rotating shaft at one end of the connecting member 51 via this rotating base. Both ends of the support member 52 are equipped with rotating ends. One end of the support member 52 is rotatably connected to the other rotating shaft of the connecting member 51 via its rotating end, and the other end is rotatably connected to the locking assembly 53 via its rotating end and a rotating shaft. The locking assembly 53 is slidably connected to the extension platform 1. Through the configuration of the above structure, during normal use, the locking assembly 53 can be locked to the extension platform 1 and supported by the support member 52, enabling stable use. When storage is required, by moving the locking assembly 53 relative to the extension platform 1, the extension platform 1 can be driven to move relative to the connecting member 51 and the support member 52, causing the extension platform 1 to draw closer to the mounting member 2 and the production cart, thereby achieving folding and storage of the extension platform 1.

In some aspects, referring to FIGS. 3-11, the locking assembly 53 can include a main body 531, a sliding member 532, and a locking member 530. The end of the support member 52 near the extension platform 1 is movably connected to the main body 531.

The sliding member 532 is fixedly connected to the main body 531. The extension platform 1 is provided with a sliding groove 11, and the sliding member 532 is slidably connected within the sliding groove 11. The extension platform 1 has a clamping part 13. A clamping position 54 is provided between the locking member 530 and the sliding member 532 for clamping the clamping part 13. The locking member 530 is movably installed on the main body 531 to adjust the size of the clamping position 54, enabling the clamping position 54 to clamp or release the clamping part 13. When clamped, the sliding member 532 and the extension platform 1 can be locked together, keeping the extension platform 1 unfolded and preventing the sliding member 532 from sliding, resulting in a stable structure. When released, the sliding member 532 can slide relative to the extension platform 1, allowing easy folding or unfolding.

In some aspects, the bottom of the main body 531 is provided with a rotating shaft. The rotating end of the support member 52 away from the connecting member 51 is rotatably connected to the rotating shaft at the bottom of the main body 531. In one example, the sliding member 532 can adopt a dovetail-shaped slider, and the sliding groove 11 adopts a dovetail groove, enabling the sliding member 532 to be stably held within the sliding groove 11 and slide therein. When the extension platform 1 is unfolded for use, the anti-disengagement member 533 is inserted into the anti-disengagement hole 12 of the extension platform 1, thereby fixing the main body 531 and the sliding member 532 relative to the extension platform 1 and achieving stable support.

In some aspects, the locking member 530 can include a locking handle 535, a connecting rod 536, and a locking block 537. The locking handle 535 and the connecting rod 536 are both movably installed on the main body 531, capable of rotating horizontally relative to the main body 531. A first moving position 5322 is provided within the sliding member 532. The locking block 537 is movably disposed within the first moving position 5322. One end of the connecting rod 536 is connected to the locking handle 535, and the other end is threadedly connected to the locking block 537. The locking block 537 has a first clamping surface 5371. The inner wall of the first moving position 5322 has a second clamping surface 5323. A clamping position 54 is formed between the first clamping surface 5371 and the second clamping surface 5323, and the clamping part 13 is positioned at this clamping position 54. During use, by rotating the locking handle 535, the connecting rod 536 is driven to rotate horizontally relative to the locking block 537. Since the connecting rod 536 is fixed in the vertical direction relative to the main body 531, it drives the locking block 537 to move towards one side of the sliding member 532 via the threaded connection, tightening the clamping position 54. This causes the clamping position 54 to clamp the clamping part 13, achieving locking between the sliding member 532 and the extension platform 1. Conversely, rotating the locking handle 535 in the opposite direction drives the locking block 537 to move towards the side of the extension platform 1, enlarging the clamping position 54, causing the clamping position 54 to release the clamping part 13, achieving unlocking between the sliding member 532 and the extension platform 1.

In some aspects, the locking handle 535 includes a toggle part 5352, a first rotating part 5354, and a trigger part 5353. The main body 531 is provided with a second moving position 5312. The toggle part 5352 is movably disposed within the second moving position 5312, capable of rotating horizontally therein, and is fixedly connected to the first rotating part 5354, protruding outside the main body 531. The connecting rod 536 can include a second rotating part 5361. The first rotating part 5354 and the second rotating part 5361 are fixedly connected via gear engagement. The main body 531 is provided with a limit slot 5311. The bottom of the second rotating part 5361 is movably disposed within the limit slot 5311, and the upper part of the second rotating part 5361 is limited by the bottom of the sliding member 532, enabling the second rotating part 5361 to be driven by the locking handle 535 to rotate horizontally within the limit slot 5311 and also to move a small distance vertically within the limit slot 5311. The connecting rod 536 further includes a threaded connecting part 5362 fixedly connected to the second rotating part 5361. The locking block 537 is provided with a threaded hole 5372, and the threaded connecting part 5362 is threadedly connected to the threaded hole 5372. The threaded connecting part 5362 is a threaded shaft. When the toggle part 5352 is rotated, it causes the locking block 537 and the threaded shaft to move relative to each other axially, thereby moving the locking block 537 axially and adjusting the size of the clamping position 54.

In some aspects, the locking assembly 53 can further include an anti-disengagement member 533. The extension platform 1 is equipped with an anti-disengagement hole 12. The anti-disengagement member 533 is elastically mounted on the main body 531. The trigger part 5353 features a first driving inclined surface 5351. The anti-disengagement member 533 can include a second driving inclined surface 5331 that is compatible with the first driving inclined surface 5351. The first driving inclined surface 5351 can move in contact with the second driving inclined surface 5331, enabling the locking handle 535 to push the anti-disengagement member 533 to disengage from the anti-disengagement hole 12. The locking assembly 53 can include a first elastic member 534. The main body 531 is provided with a third moving position 5313, and the anti-disengagement member 533 is movably positioned within the third moving position 5313. One end of the first elastic member 534 abuts against or is connected to the inner wall of the third moving position 5313, while the other end abuts against or is connected to the end of the anti-disengagement member 533 that is away from the anti-disengagement hole 12. Under normal circumstances, that is, when the extension platform 1 is in either an unfolded or folded state, the first elastic member 534 can utilize its elasticity to push the end of the anti-disengagement member 533 into the anti-disengagement hole 12 for positioning and locking. When it is necessary to change the state of the extension platform 1, such as unfolding it for use or folding it for storage, the locking handle 535 is rotated to unlock. At this moment, not only will the locking block 537 move to release the clamping part 13, but the trigger part 5353 will also move towards the anti-disengagement member 533. By the first driving inclined surface 5351 pressing against the second driving inclined surface 5331 and causing movement, the anti-disengagement member 533 is thereby pushed to disengage from the anti-disengagement hole 12, releasing the positioning. The sliding member 532 can then slide smoothly within the sliding groove 11, facilitating the folding or unfolding of the extension platform 1.

In some aspects, the anti-disengagement member 533 can include an abutting part 5332 and a positioning part 5333. The abutting part 5332 is fixedly connected to the positioning part 5333. The abutting part 5332 is movably positioned within the third moving position 5313. The sliding member 532 is provided with a through hole 5321. One end of the positioning part 5333 movably passes through the through hole 5321 and is movably connected to the anti-disengagement hole 12. The second driving inclined surface 5331 is located on the outer wall of the abutting part 5332, and the other end of the first elastic member 534 abuts against or is connected to the bottom wall of the abutting part 5332. According to the above described structure, when the toggle part 5352 is rotated outside the main body 531, the abutting part 5332 can be pushed via the trigger part 5353 to move, thereby driving the positioning part 5333 to move vertically within the third moving position 5313, causing the positioning part 5333 to disengage from the anti-disengagement hole 12 and achieving unlocking between the anti-disengagement member 533 and the extension platform 1. At this time, the anti-disengagement member 533 compresses the first elastic member 534. Similarly, when the anti-disengagement member 533 and the extension platform 1 are unlocked, rotating the toggle part 5352 in the opposite direction can drive the trigger part 5353 to disengage from the abutting part 5332. Without the pressing force from the trigger part 5353, the anti-disengagement member 533 can reset under the elastic force of the first elastic member 534.

In some aspects, both the first driving inclined surface 5351 and the second driving inclined surface 5331 are inclined surfaces with identical or similar slopes. The cooperative action of the inclined surface structures enables the second driving inclined surface 5331 to be pushed for moving while contacting the first driving inclined surface 5351.

In some aspects, the anti-disengagement hole 12 can include a first anti-disengagement hole 121. The first anti-disengagement hole 121 is set in the middle of the sliding groove 11 to achieve positioning and anti-disengagement when the extension platform 1 is unfolded.

In some aspects, the anti-disengagement hole 12 can include a second anti-disengagement hole 122. The second anti-disengagement hole 122 is set at the end of the sliding groove 11 to achieve positioning when the extension platform 1 is folded and stored.

In some aspects, a second elastic member 538 can be positioned within the first moving position 5322. One end of the second elastic member 538 abuts against or is connected to the inner wall of the first moving position 5322, while the other end abuts against or is connected to the side of the locking block 537 that is away from the sliding groove 11. The second elastic member 538 can push the side of the locking block 537 facing the extension platform 1 into the sliding groove 11 to contact the bottom wall of the sliding groove 11. This design can eliminate or reduce any slack within the sliding groove 11 and enhance the stability of the structure.

In some aspects, both the first elastic member 534 and the second elastic member 538 are standard components with elastic functions, such as springs and the like.
