[0002] In the field of wheelchair assistive devices, tabletops, as key components that improve the convenience of wheelchair users' lives, are widely used in everyday scenarios such as dining, placing items, and reading / writing. Currently, wheelchair tabletops on the market are mainly divided into two types: fixed and flip-up. Fixed tabletops are usually attached to the armrests of wheelchairs using a snap-fit ​​structure. While the structure is stable, it is extremely inflexible. Users need to remove the tabletop when getting in and out of the wheelchair, and the removed tabletop is not easy to store. While existing flip-up tables have solved the problems of disassembly and storage, most of them are just "boards" that can be flipped and folded, providing only the functions of placing items and supporting (arms). They cannot adequately meet the needs of wheelchair users, such as when going out, reading in a wheelchair, or using a mobile phone. Moreover, ordinary wheelchair tables can only be laid flat, which does not meet ergonomic requirements. Prolonged use may lead to fatigue, discomfort, or even worsening of disability, indicating a lack of functionality. Utility Model Content

The movable seat 304 can rotate based on the damping pivot 303, and the metal clamp 305 can rotate based on the damping pivot, which is used to change the angle and position of the table assembly 100.

[0024] like Figure 4 , Figure 5 and Figure 6 As shown, the tabletop body 101 has a hand groove 105 on the side of the T-shaped groove 102. The hand groove 105 helps the user to easily open the support plate 103 by pressing it.

[0025] like Figure 4 , Figure 5 and Figure 6 As shown, a circular groove 107 is formed on the surface of the table body 101, and a hollow groove 108 is formed on the inner side of the circular groove 107. A support block is fixedly connected to the bottom of the table body 101. The table body 101 is made of polymer material, and the support block is integrally formed with the table body 101. The support block is used to support the placement mechanism 200.

[0026] like Figure 5 and Figure 6 As shown, the limiting component 220 includes a movable shaft 221, with knobs 222 fixedly connected to both ends of the movable shaft 221. The movable shaft 221 is rotatably connected to the table body 101 via a damping bearing. A limiting block is fixedly connected to the middle section of the movable shaft 221. The movable shaft 221 passes through the hollow groove 108, and the limiting block is located inside the hollow groove 108.

[0027] like Figure 5 and Figure 6 As shown, the placement component 210 includes a mesh bag 211 and a metal connecting ring 212. The mesh bag 211 and the metal connecting ring 212 are fixedly connected.

The wheelchair body includes a frame 400, which is the prior art and is made of metal. A connecting mechanism 300 is connected to the surface of the frame 400. Connecting block 1 301 and connecting block 2 302 are clamped to the surface of the frame 400 by bolts and nuts.

[0030] This application allows the position of the table assembly 100 to be adjusted via the connecting mechanism 300, enabling the table assembly 100 to rotate based on the connecting mechanism 300 and be stored inside the armrest of the wheelchair body, thus avoiding obstruction of the user's body and providing a certain degree of portability. The support plate 103 can be supported by two support rods 104 in conjunction with the limiting groove on the table body 101, at which point the support plate 103 can be used as a stand for mobile phones or books. The metal connecting ring 212 of this application, together with the mesh bag 211, can hold some easily rolling items (such as cylindrical water cups, pen holders, etc., which may slip off the surface of the table body 101 due to the uneven angle of the table body 101). This gives this application multiple functions.

[0031] When the tabletop assembly 100 is in the retracted state, the limiting component 220 can be rotated to disengage the limiting block from the limiting groove. At this time, the placement component 210 can rotate based on the damping shaft, and finally rotate 90 degrees under the action of gravity, so that the metal connecting ring 212 contacts the support block at the bottom of the tabletop body 101. (The support block is used to support the metal connecting ring 212 and prevent the metal connecting ring 212 from rotating too much and tilting, so that the internal items are not placed stably.) At this time, the placement mechanism 200 can still place items such as water cups in the retracted state of the tabletop assembly 100, which is convenient for users.

[0032] The above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.
