[0002] Current transfer vehicle structures such as Figure 1 As shown, the main components include a frame (a), with two seat cushion frames (b) arranged on the left and right sides of the frame. Each seat cushion frame is connected to a seat cushion (c) that can be flipped up and down. When the user needs to use the vehicle, the two seat cushions must first be flipped up to the storage position, making the front of the transfer vehicle open, so that the user can step into the transfer vehicle. Then, the two seat cushions are flipped inward and downward to the unfolded position, so that the user's buttocks (d) can sit on the two seat cushions. However, with this connection method, when the seat cushions are flipped from the storage position to the unfolded position, or vice versa, space needs to be reserved inside the transfer vehicle for the seat cushions to flip. This causes caregivers to have to lift the user to a higher position, raising their buttocks from height H1 to height H2 in the attached diagram, thus increasing the workload of caregivers. Therefore, the applicant has improved and perfected the transfer vehicle to solve the above problems and provide it for consumers to choose from. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 2 to 9 As shown, a moving vehicle includes a frame 1, two seat cushions 2 arranged on the left and right, and several casters 3. The casters 3 are installed at the bottom of the frame 1 and are used to move the frame 1. The characteristic is that: any seat cushion 2 is provided with an inclined shaft connecting assembly 4 between it and the frame 1. The seat cushion 2 is tilted and rotated between a use position P1 and a storage position P2 through the inclined shaft connecting assembly 4, and switches between an unfolded state and a vertical state as it rotates. Furthermore, a footrest 5 is connected to the frame 1 relative to the rear of the seat cushion 2.

[0028] This moving cart has a footrest at the back of the seat. When the user needs to place the footrest under their buttocks, they simply need to... Figure 3 As shown, place your knees against the footrests, your feet on the footrests of the frame, and then use your knees as a fulcrum to lean your body forward. The two seat cushions on either side should then... Figure 4 As shown, the user only needs to move the buttocks d from Figure 4 The H1 height was raised to Figure 4 The H3 height allows it to be tilted and inserted under the user's buttocks from the storage position, or it can be tilted and rotated out of the storage position immediately after the user's buttocks leave the seat cushion 2. The operation is simple, quick, and easy to switch between positions. Compared to... Figure 1The H2 height in the middle can significantly reduce the height that users need to lift their hips, thus reducing the workload of caregivers.

[0029] The frame 1 includes at least two seat cushion frames 10 arranged on the left and right. The seat cushion 2 is connected to the seat cushion frame 10 through a diagonal shaft connecting assembly 4. The use position is located between the two seat cushion frames 10, and the storage position is located on the upper side of either seat cushion frame 10.

[0030] The structure uses the seat cushion frame 10 to support the seat cushion 2, allowing the two seat cushions 2 to tilt and rotate relative to each other. When rotating from the use position to the storage position, the seat cushion 2 is in a vertical position on the upper side of the seat cushion frame 10, which does not occupy the lateral space of the transfer vehicle and has a better storage effect. When rotating from the storage position to the use position, the seat cushion 2 folds from the vertical position to the unfolded position, without the need for additional angle adjustment, making the operation simpler.

[0031] The frame 1 also includes a base 11 and two uprights 12 arranged on the upper side of the base 11. The foot stop 5 is fixed between the two uprights 12 by the connecting structures 6 on its left and right sides. In the general frame 1 structure, the uprights 12 are the thickest and have high structural strength. When the foot stop 5 is under force, the uprights 12 are not easily deformed.

[0032] The base 11 is provided with a foot pedal 112, which is located below the foot stop 5, and the top surface of the foot pedal 112 is provided with an anti-slip layer 113. The foot pedal 112 provides a place for the user's feet to rest, and the structure of the anti-slip layer 113 is added to prevent the user from slipping. The anti-slip layer 113 can be an integrally formed rib or a raised structure.

[0033] The footrest 5 is inclined between the two columns 12 with the upper end towards the rear and the lower end towards the front; the footrest 5 with this structure can better fit the user's knee and calf, increase the force-bearing area, and reduce the pressure on the knee.

[0034] In this embodiment, the inclined shaft connection assembly 4 includes a bushing 41 and a rotating shaft 42 rotatably connected within the bushing 41. The bushing 41 is inclinedly connected to the end of the seat cushion frame 10, and the rotating shaft 42 is inclinedly connected to one side of the seat cushion frame 10. The rotating shaft 42 is provided with a rotation limiting structure that cooperates with the bushing 41.

[0035] The rotation limiting structure includes a limiting plate 411 disposed inside the bushing 41. The limiting plate 411 has an arc-shaped limiting groove 412 corresponding to the rotation angle of the seat cushion 2. The end face of the rotating shaft 42 has a threaded hole 421 corresponding to the arc-shaped limiting groove 412. By passing the fastening bolt 43 through the arc-shaped limiting groove 412 and the threaded hole 421, the rotating shaft 42 and the bushing 41 are assembled and connected, and the fastening bolt 43 and the arc-shaped limiting groove 412 form a limiting fit.

[0036] The rotation limiting structure includes a limiting swing block 422 and an arc groove 413. The limiting swing block 422 is fixed on the outer wall of the rotating shaft 42, and the arc groove 413 is formed on the inner circumferential wall of the bushing 41. Through the cooperation of the limiting swing block 422 and the arc groove 413, the rotating shaft 42 is limited to rotate within the bushing 41.

[0037] When installing the inclined shaft connection assembly 4 of the above structure, the seat cushion 2 is inserted into the bushing 41 using the rotating shaft 42. At this time, the threaded hole 421 corresponds to the arc-shaped limiting groove 412, and the limiting swing block 42 is inserted into the arc-shaped sliding groove 413. Then, the fastening bolt 43 is screwed into the threaded hole 421, and the head of the fastening bolt 43 is used to limit the engagement with the limiting plate 411, so that the bushing 41 and the rotating shaft 42 are fastened to each other. Moreover, during the rotation of the seat cushion 2, the fastening bolt 43 can only slide in the arc-shaped limiting groove 412, and the limiting swing block 422 can only slide in the arc-shaped sliding groove 413, thus controlling the rotation range between the use position and the storage position.

[0038] In addition, the end cap 44 is detachably connected to the port of the bushing 41 corresponding to the head of the fastening bolt 43; the end cap 44 covers the port of the bushing 41, so that the fastening bolt 43 and the arc-shaped limiting groove 412 will not be exposed, preventing the user's finger from being inserted into the arc-shaped limiting groove 412 and causing a pinching accident.

[0039] In this embodiment, the end cap 44 is interference-fitted onto the port. In other embodiments, the end cap 44 may also be threaded or snap-fitted onto the port.

[0040] The footrest 5 includes a footrest 51 and a first sponge pad 52. The first sponge pad 52 is integrally wrapped around the outer perimeter of the footrest 51. The elastic sponge pad 52 improves the comfort of the footrest 5. The sponge pad 52 has two side-by-side leg positioning arc surfaces 521 on the side facing the seat cushion 2. When the user's knees and calves are against the first sponge pad 52, the leg positioning arc surfaces 521 can stabilize the distance between the legs and prevent the knees from sliding when they are against the footrest 5.

[0041] The connecting structure 6 mainly includes a first pin sleeve 61, a second pin sleeve 62, and a pin 63. The first pin sleeve 61 is fixed to the inner side of the column 12. The second pin sleeve 62 is fixed to the side of the foot stop 5 and extends to a bushing 621 that is inserted into the first pin sleeve 61. The pin 63 is inserted into the second pin sleeve 62 and the first pin sleeve 61 in sequence, and its bottom end protrudes out of the first pin sleeve 61 and is provided with a spring buckle 631.

[0042] This structure utilizes pin 63 to enable quick installation and removal of foot stop 5. During installation, foot stop 5 is first inserted into first pin sleeve 6 via bushing 621 to fix foot stop 5 to column 12. This ensures that foot stop 5 is stable without manual support before pin 63 is inserted into second pin sleeve 62. Finally, after pin 63 is inserted into second pin sleeve 62 and first pin sleeve 61 in sequence, its spring clip 631 is engaged below first pin sleeve 61, thereby fixing foot stop 5 between the two columns 12 and preventing it from being pulled out at will.

[0043] The seat cushion 2 includes a seat plate 21 and a second sponge pad 22. The side of the seat plate 21 is connected to a bearing 23. The rotating shaft 42 is coaxially fixed on the bearing 23, and a reinforcing structure is provided between the bearing 23 and the seat plate 21. The second sponge pad 22 is integrally wrapped around the outer periphery of the seat plate 21. The elastic second sponge pad 22 improves the comfort of the seat cushion.

[0044] Specifically, the seat cushion 21 includes a main seat cushion 211, with a side seat cushion 212 obliquely connected to the side of the main seat cushion 211. The bearing 23 is fixed to the outside of the side seat cushion 212, and the rear side of the main seat cushion 211 is folded upward to form a hip-limiting rocker 213. The hip-limiting rocker 213 prevents the user's buttocks from sliding backward when sitting on the seat cushion 2.

[0045] The aforementioned reinforcing structure mainly includes several metal reinforcing ribs 214. One end of each metal reinforcing rib 214 is welded to the side wall of the bearing seat 23, and the other end radiates outward from the bearing seat 23 and is welded to the bottom surface of the seat side plate 212, the bottom surface of the seat main plate 211, and in some cases, the bottom surface of the buttock limiting rocker plate 213. This structure can improve the strength of the seat plate 21, making it less prone to deformation and increasing its load-bearing capacity.

[0046] A seatbelt 14 that can be detached or fastened is movably connected between the top ends of the two uprights 12; after the user sits on the seat cushion 2, the seatbelt 14 is fastened to the user's back to prevent the user from falling backward.

[0047] The seat frame 10 is connected to the front side of the column 12, and the handle frame 13 is connected to the rear side of the column 12. The handle frame 13 and the seat frame 10 are bent upward or downward respectively, and the two form an "S" shape. The bent seat frame 10 allows space to be reserved on the upper side for the seat 2 to be stored, while the bent handle frame 13 does not need to be bent, and the lines make the transfer vehicle more beautiful.

[0048] The base 11 includes two base rods 111 arranged on the left and right. Several casters 3 are installed on the front and rear ends of the base rods 111. The foot pedal 112 is connected between the two base rods 111. The casters 3 on the transfer cart are mainly swivel casters, which can change direction at will when the transfer cart moves, making the operation more flexible.
