[0035] Reference Figures 2-3 , when not in use or during transportation, by removing the seat cushion assembly 5 from the auxiliary chair main body 1, the lack of fixation of the seat cushion assembly 5 to the auxiliary chair main body 1 makes the left armrest support 3 and the right armrest support 4 in an active state relative to the backrest support 2. Personnel rotate the left armrest support 3 and the right armrest support 4 relative to the backrest support 2, thereby realizing folding, achieving the effect of not occupying space during transportation and convenient storage.

[0036] Refer to Figure 4 、 6As shown in FIG. -10, as a preferred embodiment, the seat cushion assembly 5 includes more than one set of lifting devices 12 for lifting the seat cushion 7. The lifting devices 12 are arranged on the seat cushion frame 6. The lifting device 12 includes a support seat 13, a pneumatic rod 14, a strut bracket 15 and a sliding link 16. The support seat 13 is connected to the seat cushion frame 6. The first end of the pneumatic rod 14 is connected to the support seat 13. The second end of the pneumatic rod 14 is connected to the first end of the strut bracket 15. The second end of the strut bracket 15 is connected to the first end of the sliding link 16. The strut bracket 15 is connected to the seat cushion 7. The support seat 13 is provided with a sliding groove 17 for the second end of the sliding link 16 to move. The seat cushion frame 6 is provided with a limiting groove 26 corresponding to the sliding link 16. The sliding link 16 is placed in the limiting groove 26. Wherein, the pneumatic rod 14 is lifted to drive the strut bracket 15 and the seat cushion 7 to be lifted. The second end of the sliding link 16 can linearly move in the sliding groove 17. The sliding link 16 placed in the limiting groove 26 limits the amplitude of the left - right swing of the seat cushion 7.

[0037] As Figure 7 , Figure 8 and Figure 12, the lifting device 12 is used to assist users with difficulty standing or postoperative patients to provide lifting assistance when standing, reducing the burden. In implementation, the lifting device 12 is at least one group or more than one group. Under the action of meeting the lifting function, one group can be selected; in this embodiment, two groups of lifting devices 12 are selected, and the two groups of lifting devices 12 are respectively arranged on both sides of the seat cushion 7 to achieve symmetric distribution. Preferably, the lifting device 12 is realized by using a support base 13, a pneumatic rod 14, a support rod bracket 15 and a sliding link 16. Among them, the support base 13 is fixed on the seat cushion frame 6 by screws, the first end of the pneumatic rod 14 is fixed on the support base 13 by screws, the second end of the pneumatic rod 14 is a telescopic end, the second end of the pneumatic rod 14 is fixed to the first end of the support rod bracket 15 by screws, the support rod bracket 15 is fixed to the seat cushion 7 by screws, the second end of the support rod bracket 15 is connected to the first end of the sliding link 16, and a sliding groove 17 is provided in the front-to-back direction of the support base 13, and the second end of the sliding link 16 is movably placed in the sliding groove 17 so that during the lifting of the seat cushion 7, the moving position of the sliding link 16 is satisfied, and a limiting groove 26 is provided in the seat cushion frame 6 at the position corresponding to the sliding link 16. Since the installation of the pneumatic rod 14 is loose, the gap between the seat cushion frame 6 and the seat cushion 7 will be enlarged into a left-right swinging state at the tail of the seat cushion 7, resulting in the subsequent locking assembly 18 being unable to successfully position with the locking buckle 19 of the seat cushion 7. Therefore, by providing the limiting groove 26 in the seat cushion frame 6 and combining it with the sliding link 16, and using the way that the sliding link 16 is always in the limiting groove 26, the positioning of the seat cushion 7 is realized, which is convenient for the locking rod 21 to be connected and fixed with the locking buckle 17 on the seat cushion frame.

[0038] Its driving process is as follows: when the user or patient stands, the second end of the pneumatic rod 14 jacks up to drive the seat cushion 7 to jack up, and the user or patient on the seat cushion 7 can obtain jacking assistance and is convenient for standing. The jacking of the seat cushion 7 drives the second end of the sliding link 16 to move in the sliding groove 17. At the same time, the sliding link 16 is in the limiting groove 26, and the left-right swing amplitude of the seat cushion 7 is restricted by the limiting groove 26 in the left-right direction, that is, the positioning of the seat cushion 7 is realized, which is convenient for the subsequent connection of the locking rod 21 and the locking buckle 19.

[0039] Reference Figures 6-11As shown, the seat cushion assembly 5 includes a locking assembly 18 for locking the seat cushion 7 to prevent the lifting device 12 from lifting. The locking assembly 18 includes a locking buckle 19, a guide seat 20, and a locking rod 21. Among them, the locking buckle 19 is provided on the seat cushion 7, the guide seat 20 is installed on the support seat 13, and the locking rod 21 passes through the support seat 13 and the locking buckle 19 in sequence to fix the seat cushion 7 on the seat cushion frame 6. At least a part of the locking rod 21 is outside the seat cushion frame 6, and the locking rod 21 is pulled by an external force to disengage from the locking buckle 19 to release the fixation between the seat cushion 7 and the seat cushion frame 6.

[0040] When a user or a patient sits on the seat cushion 7, since the pneumatic rod 14 has a force to lift the user or the patient, it is not convenient for the user or the patient to sit and use. For this reason, by setting a locking assembly 18 on the seat cushion assembly 5, its main function is to be used as a switch for the pneumatic rod 14. For example, when a user or a patient sits on the seat cushion 7, the seat cushion 7 and the seat cushion frame 6 are in a combined state, and the user or the patient fixes the seat cushion 7 by connecting the sliding locking rod 21 with the locking buckle 19. When the user or the patient needs lifting assistance, the user or the patient pulls the locking rod 21 to release the connection with the locking buckle 19, and the pneumatic rod 14 drives the seat cushion 7 to lift, realizing the standing assistance for the user or the patient.

[0041] Specifically, the locking assembly 18 includes a locking buckle 19, a guide seat 20, and a locking rod 21. The locking buckle 19 is connected to the seat cushion 7. The locking buckle 19 has an opening to facilitate the locking or unlocking of the locking rod 21 passing through. At least two openings are provided on the guide seat 20, and the two openings are arranged front and back to form a guide for the locking rod 21. The locking rod 21 passes through the guide seat 20 and the locking buckle 19 in sequence. The end of the locking rod 21 can be set to be placed in the seat cushion frame 6, and the end of the locking rod 21 can be set with a ball head to facilitate the user or the patient to hold and move.

[0042] Specifically, the front end of the seat cushion 7 is connected to the front end of the seat cushion frame 6 through a hinge 22. The lifting method of the seat cushion 7 is an inclined lifting, so as to facilitate assisting a user or a patient in a sitting state to stand up. The shape of the seat cushion 7 can be prepared as a toilet seat shape or a common seat cushion 7 shape. Prepared as a toilet seat shape, it can facilitate the user or the patient to stand up after using the toilet.

[0043] Refer to Figure 5 As shown, the backrest bracket 2 includes a backrest telescopic rod 23, and the backrest telescopic rod 23 adjusts the telescopic length relative to the backrest bracket 2; the left armrest bracket 3 includes a left telescopic rod 24, and the left telescopic rod 24 adjusts the telescopic length relative to the left armrest bracket 3; the right armrest bracket 4 includes a right telescopic rod 25, and the right telescopic rod 25 adjusts the telescopic length relative to the right armrest bracket 4.

[0044] In implementation, in order to solve the technical problem of the adjustable height of the auxiliary chair main body 1, the backrest support 2 is provided with a backrest telescopic rod 23, the left armrest support 3 is provided with a left telescopic rod 24, and the right armrest support 4 is provided with a right telescopic rod 25. The telescopic method is to uniformly set adjustment holes on the telescopic rod and cooperate with the elastic convex posts on the support to achieve telescopic adjustment.

[0045] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
