Description
Technical Field
The utility model relates to an adjusting device especially relates to an electronic wheelchair seat slope adjustment mechanism.
Background
Nowadays, wheelchairs become indispensable tools for riding instead of walk for old people and disabled people with inconvenient actions, and have wide application objects. At present, the chair angles of most wheelchairs can not be adjusted, so that a user can not conveniently get on or off the wheelchairs, and particularly for old people or disabled people with inconvenient legs and feet, the user can get on or off the wheelchairs more laboriously; moreover, when the wheelchair ascends or descends, the wheelchair seat is prone to being overturned backwards or being planted forwards due to the fact that the inclination angle of the wheelchair seat cannot be adjusted, and potential safety hazards exist.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing an electric wheelchair seat inclination adjusting mechanism which can adjust the inclination angle of the wheelchair seat at will and has simple structure.
The technical scheme is as follows: electronic wheelchair seat slope adjustment mechanism, including seat fixed plate assembly and bottom plate assembly, fixed plate assembly front end and bottom plate assembly front end swing joint, fixed plate assembly rear end sets up the top spin axle, bottom plate assembly rear end sets up down the rotation axle, top spin axle and lower rotation axle pass through driving medium swing joint, electric telescopic handle is connected to the driving medium.
Preferably, the transmission part comprises a pair of upper fixed connecting rods, a first lower fixed connecting rod and a second lower fixed connecting rod, the pair of upper fixed connecting rods are arranged on the upper rotating shaft, the first lower fixed connecting rod and the second lower fixed connecting rod are arranged on the lower rotating shaft, and the pair of upper fixed connecting rods are respectively movably connected with the first lower fixed connecting rod and the second lower fixed connecting rod.
Preferably, the second lower fixed connecting rod is splayed, the upper end of the second lower fixed connecting rod is connected with the upper fixed connecting rod, and the lower end of the second lower fixed connecting rod is connected with the electric telescopic rod.
Preferably, the electric telescopic rod is controlled by a power device.
Preferably, the power device is fixed on the lower fixing plate assembly through a power device fixing plate.
Has the advantages that: compared with the prior art, the utility model, have following advantage: 1. the angle of the seat can be adjusted steplessly, so that the wheelchair can be conveniently moved up and down, and the wheelchair is safer when moving up and down; 2. simple structure and convenient operation.

FIG. 2 is a schematic structural view of the utility model after the structure is opened;
fig. 3 is a schematic view of the structure of the utility model after being folded.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
Referring to the drawings, in the drawings, 1, an upper fixing plate assembly; 2. a lower fixing plate assembly; 3. an upper fixed connecting rod; 4. a first lower fixed link; 5. a second lower fixed link; 6. rotating the shaft upwards; 7. a lower rotating shaft; 8. an electric telescopic rod; 9. a power plant; 10. the power device stator.
As shown in fig. 1, electronic wheelchair seat slope adjustment mechanism, including the upper fixed plate assembly 1 and the bottom plate assembly 2 of seat, the 2 front end swing joint of upper fixed plate assembly 1 front ends and bottom plate assembly, the 1 rear end of upper fixed plate assembly sets up rotation axis 6, go up to set up a pair of fixed connecting rod 3 on rotation axis 6, 2 rear ends of bottom plate assembly set up rotation axis 7 down, set up fixed connecting rod 5 under first fixed connecting rod 4 and the second on rotation axis 7 down, a pair of fixed connecting rod 3 of going up respectively with fixed connecting rod 5 swing joint under first fixed connecting rod 4 and the second, fixed connecting rod 5 is the splayed under the second, the upper end is connected with last fixed connecting rod 3, the lower extreme is connected with electric telescopic handle 8. The electric telescopic rod 8 is controlled by a power device 9, and the power device 9 is fixed on the lower fixing plate assembly 2 through a power device fixing plate 10.
The utility model discloses a theory of operation is: when the wheelchair seat needs to be adjusted to be in an inclined state, the power device 9 drives the electric telescopic rod 8 to extend out to push the lower end of the second lower fixing connecting rod 5 to move backwards, the second lower fixing connecting rod 5 rotates clockwise around the lower rotating shaft 7 to drive the upper fixing connecting rod 3 hinged with the upper end of the second lower fixing connecting rod 5 to rotate clockwise around the upper rotating shaft 6, and the rear end of the upper fixing plate assembly 1 is driven to be lifted, so that the seat is inclined and lifted to form a seat inclination angle, as shown in fig. 2. When the seat needs to be adjusted to be in a horizontal state, the power device 9 drives the electric telescopic rod 8 to contract to drive the lower end of the second lower fixed connecting rod 5 to move forwards, the second lower fixed connecting rod 5 rotates anticlockwise around the lower rotating shaft 7 to drive the upper fixed connecting rod 3 hinged with the upper end of the second lower fixed connecting rod 5 to rotate anticlockwise around the upper rotating shaft 6, and the rear end of the upper fixed plate assembly 1 is driven to descend to form a seat horizontal angle, as shown in fig. 3, so that the function of stepless adjustment of the seat angle is realized.
