Abstract
Description
Technical Field
[0001] The utility model relates to an electric wheelchair controller adjustment structure and an electric wheelchair, belonging to the technical field of electric wheelchairs. Background Art
[0002] In an electric wheelchair, the controller needs to keep the direction constant during adjustment. To solve the above problem, the existing controller adjustment forms on the market mostly adopt a four-bar solution, which uses rods to form a parallelogram structure and uses its two-to-two parallel characteristics to achieve the effect of keeping the direction constant during the controller adjustment. However, the existing solution also has some shortcomings. On the one hand, the two movable rods that form the parallelogram have a safety hazard of pinching the hand during movement; on the other hand, this structure has a small range of motion and can only rotate in one direction, which is difficult to meet the needs of most users. Utility Model Content
[0003] The utility model aims to overcome the deficiencies in the prior art and to provide an electric wheelchair controller adjustment structure and an electric wheelchair, which can realize self-rotation and self-retention of the controller, can be adjusted in both directions, and have a large adjustment range.
[0004] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:
[0005] In a first aspect, the utility model provides an electric wheelchair controller adjustment structure, comprising a fixing plate connected to a wheelchair body, a mounting plate connected to a controller, and a support assembly disposed between the fixing plate and the mounting plate;
[0006] The fixing plate is hinged to the supporting assembly via a first rotating shaft, and the mounting plate is hinged to the supporting assembly via a second rotating shaft.
[0007] The first rotating shaft and the second rotating shaft are connected through a synchronous rotating assembly, and the synchronous rotating assembly is used to drive the second rotating shaft to rotate when the supporting assembly rotates in a certain direction around the first rotating shaft, so as to keep the orientation of the controller constant.
[0008] Furthermore, the synchronous rotation assembly includes a first synchronous wheel, a second synchronous wheel and a synchronous belt, and the synchronous belt connects the first synchronous wheel and the second synchronous wheel at the same time; the first rotating shaft and the second rotating shaft are fixedly connected to the first synchronous wheel and the second synchronous wheel respectively.
[0009] Furthermore, the controller adjustment structure also includes a cover shell, the synchronous rotation assembly is arranged inside the cover shell, and the first rotating shaft and the second rotating shaft are both hinged to the cover shell, so that the cover shell can rotate around the axis of the first rotating shaft and the second rotating shaft.
[0010] Furthermore, the cover shell includes an upper cover and a bottom groove, the first synchronous wheel, the second synchronous wheel, and the synchronous belt are placed in the bottom groove, and the first rotating shaft and the second rotating shaft both pass through the upper cover and the bottom groove.
[0011] Furthermore, the protruding ends of the first rotating shaft and the second rotating shaft are provided with internal threads or external threads, which pass through the other end of the cover shell and are connected with screws or nuts.
[0012] Furthermore, gaskets are provided between the first rotating shaft, the second rotating shaft, and the upper cover and the bottom groove of the housing to play a role in buffering and reducing wear.
[0013] Furthermore, the diameters of the first synchronous wheel and the second synchronous wheel are the same, so that the rotation angle of the synchronous belt relative to the first synchronous wheel is consistent with the rotation angle relative to the second synchronous wheel, ensuring that the controller has a constant direction during movement.
[0014] In a second aspect, the utility model further provides an electric wheelchair, wherein the electric wheelchair is equipped with the electric wheelchair controller adjustment structure described in the first aspect.
[0015] Compared with the prior art, the utility model has the following beneficial effects:
[0016] The electric wheelchair controller adjustment structure of the utility model, through the cooperation of the synchronous rotation component, the support component and the two rotating shafts, makes the controller rotate around the axis of the first rotating shaft and the axis of the second rotating shaft synchronously, so that the controller can rotate from the inside to the outside and from the outside to the inside, and can be freely adjusted within a range of 360 degrees. During the adjustment process, the direction of the controller remains unchanged, and the self-rotation and self-holding of the controller are realized. The controller can be adjusted in both directions and has a large adjustment range.
[0017] The regulating structure of the utility model has a small overall volume and a compact structure, and the synchronously rotating components can be packaged as a whole, which has good aesthetics and no safety hazard of pinching hands. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0026] Example 1
[0027] like Figure 1 and Figure 2 As shown, the utility model provides an electric wheelchair controller adjustment structure, including a fixing plate 100, a first rotating shaft 200, a first synchronous wheel 300, a synchronous belt 400, a second rotating shaft 500, a second synchronous wheel 600, a mounting plate 700, a controller 701 and a cover 800.
[0028] In this embodiment, one end of the fixing plate 100 is fixedly connected to the armrest of the electric wheelchair, and the other end is fixedly installed with the first rotating shaft 200; one end of the mounting plate 700 is fixedly connected to the controller, and the other end is fixedly installed with the second rotating shaft 500.
[0029] The synchronous belt 400 connects the first synchronous wheel 300 and the second synchronous wheel 600 at the same time, and the first synchronous wheel 300 , the synchronous belt 400 and the second synchronous wheel 600 are encapsulated in the housing 800 .
[0030] The first synchronous wheel 300 is fixed on the first rotating shaft 200 and is hinged to the cover shell 800 so that the cover shell 800 can rotate around the axis of the first rotating shaft 200 .
[0031] The second synchronous wheel 600 is fixed on the second rotating shaft 500 and is hinged to the cover shell 800 so that the cover shell 800 can rotate around the axis of the second rotating shaft 500 .
[0032] The housing 800 includes an upper cover 801 and a bottom groove 802. The first synchronous wheel 300, the second synchronous wheel 600, and the synchronous belt 400 are placed in the bottom groove 802. The first rotating shaft 200 and the second rotating shaft 500 pass through the upper cover 801 and the bottom groove 802. Gaskets 900 are provided between the first rotating shaft 200 and the second rotating shaft 500 and the upper cover 801 and the bottom groove 802 to buffer and reduce wear. The protruding ends of the first rotating shaft 200 and the second rotating shaft 500 are provided with external threads, which pass through the other end of the housing 800 and are connected to a nut.
[0033] 1. If Figure 3 and Figure 4 As shown, when the manually operated support assembly (cover 800) rotates clockwise around the first rotating shaft 200, since the first rotating shaft 200 is fixedly connected to the fixed plate 100 and the first synchronous wheel 300, the first synchronous wheel 300 moves counterclockwise relative to the support assembly, and drives the second synchronous wheel 600 to move synchronously through the synchronous belt 400. The second rotating shaft 500 is fixedly connected to the second synchronous wheel 600, and the second rotating shaft 500 is fixedly connected to the mounting plate 700, thereby driving the mounting plate 700 and the controller 701 to move counterclockwise relative to the support assembly around the second rotating shaft 500.
[0034] The first synchronous wheel 300 and the second synchronous wheel 600 are equal in size and shape. At this time, the rotation angle of the synchronous belt 400 relative to the first synchronous wheel 300 is consistent with the rotation angle of the second synchronous wheel 600, ensuring that the controller 701 has a constant direction during movement.
[0035] 2. The same applies when the manually operated support assembly rotates counterclockwise around the first rotating shaft 200.
[0036] Example 2
[0037] This embodiment provides an electric wheelchair, which is equipped with the electric wheelchair controller adjustment structure described in Embodiment 1.
