Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seats, in particular to a multifunctional seat for disabled people to move around. Background Art
[0002] People with lower limb disabilities usually use disability seats to help them move over a large range. In existing disability seats, the back panels and side panels are usually fixed in design. When a disabled person needs to move from the seat to other areas, he or she needs help from others and cannot rely on his or her own abilities to move over a large range. In view of this, the present invention provides a seat that can help disabled people achieve transfers by their own strength. Utility Model Content
[0003] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a multifunctional chair for the mobility of disabled persons.
[0004] Technical solution: A multifunctional mobile chair for disabled people, including a bracket, the front and rear sides of the lower part of the bracket are rotatably connected to rollers, a seat plate is fixed to the bracket, the left and right sides of the bracket are respectively rotatably connected to side panels via a first rotating shaft, and the rear side of the bracket is rotatably connected to a back panel via a second rotating shaft. The bracket is provided with a driving component for driving the side panels and the back panel to rotate synchronously.
[0005] Furthermore, the drive assembly includes a motor, a bevel gear set and a belt assembly. The bevel gear set includes two pairs of mutually meshing bevel gears. A bevel gear is fixed to one end of rotating shaft one, and a bevel gear is fixed to both ends of rotating shaft two. A motor is installed at the bottom of the seat plate, and the output shaft of the motor is connected to one of the rotating shafts one through a belt assembly.
[0006] Furthermore, the roller is provided with a plurality of through holes.
[0007] Furthermore, it also includes a limit block and an electric push rod. The electric push rod is installed at the lower part of the bracket. The limit block is fixed on the telescopic rod of the electric push rod, and the limit block is used to engage with the through hole.
[0008] Furthermore, it also includes a handrail, and the front parts of the left and right sides of the bracket are fixed with a handrail.
[0009] Furthermore, it also includes a foot pedal, and the foot pedal is fixedly connected to the lower front part of the bracket.
[0010] Beneficial effects: The side panels and back panels of the utility model can be rotated synchronously according to the needs of disabled people, so that disabled people can more easily transfer from the seat to other areas, such as from the seat to the bed or wheelchair, etc., which greatly reduces the difficulty and discomfort during the transfer process, thereby improving their ability to take care of themselves.

DETAILED DESCRIPTION
[0016] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0017] See also Figure 1-Figure 4 A multifunctional chair for disabled people to move around, including a bracket 1, the front and rear sides of the lower part of the bracket 1 are rotatably connected to rollers 2, the rollers 2 have a plurality of through holes 201, a seat plate 3 is fixed to the bracket 1, the left and right sides of the bracket 1 are rotatably connected to side plates 4 through a rotating shaft 1 401 respectively, the rear side of the bracket 1 is rotatably connected to a back plate 5 through a rotating shaft 2 501, and a driving component 6 for driving the side plates 4 and the back plate 5 to rotate synchronously is provided on the bracket 1.
[0018] The driving assembly 6 includes a motor 601, a bevel gear set 602 and a belt assembly 603. The bevel gear set 602 includes two pairs of bevel gears that mesh with each other. A bevel gear is fixed to one end of each rotating shaft 401 close to the rotating shaft 2 501, and a bevel gear is fixed to both ends of the rotating shaft 2 501. The motor 601 is installed at the bottom of the seat 3, and the output shaft of the motor 601 is connected to the rotating shaft 1 401 on the left side through the belt assembly 603.
[0019] It also includes a limit block 7 and an electric push rod 8. The electric push rod 8 is installed at the lower part of the bracket 1. The limit block 7 is fixed to the telescopic rod of the electric push rod 8. When the telescopic rod of the electric push rod 8 is extended, it will drive the limit block 7 to move to engage with the through hole 201 on the roller 2, thereby preventing the movement of the roller 2, so that the seat can be fixed in a specific position when needed.
[0020] The bracket 1 further comprises a handrail 9 , which is fixedly connected to the front of the left and right sides of the bracket 1 . The handrail 9 can help disabled people maintain balance.
[0021] The bracket 1 further includes a foot pedal 10 , which is fixedly connected to the lower front portion of the bracket 1 . The foot pedal 10 can provide a stable support point for the legs of a disabled person.
[0022] Working principle: When a disabled person needs to transfer from the seat to other areas, the driving component 6 is used to control the synchronous rotation of the side panels 4 and the back panel 5. Specifically, the motor 601 is started, and the motor 601 transmits power to one of the rotating shafts 401 through the belt component 603. Since the rotating shaft 1 401 and the rotating shaft 2 501 are fixed with mutually meshing bevel gears, the power will be transmitted to the rotating shaft 2 501 and the other rotating shaft 1 401, thereby realizing the synchronous rotation of the back panel 5 and the two side panels 4, so that the disabled person can more easily transfer from the seat to other areas through the back panel 5 or the side panel 4.
