Description

Technical Field

[0001] This utility model relates to the field of wheelchair manufacturing, specifically to a controller tray holder for wheelchair handles. Background Technology

[0002] Electric wheelchairs are an important assistive tool widely used in the daily lives of people with mobility impairments or disabilities. However, there are significant differences in the usage habits of different users of electric wheelchairs. These differences are not only reflected in the basic operational needs of the wheelchair, but also in the operation methods and function settings of the controller.

[0003] Specifically, different users have different preferences regarding the deflection angle of the controller. Some users may prefer the controller to deflect outwards, often because they need more agility in maneuvering their wheelchairs to turn or avoid obstacles in confined spaces. For example, when used in indoor environments such as homes or offices, an outward-deflecting controller can help users better adapt to the complex terrain of these environments.

[0004] Other users may prefer the controller to veer inward, often because they want smoother wheelchair control when using it outdoors or in public places, especially when making sharp turns or going uphill / downhill. An inward-veer controller provides a more stable feel, reduces wheelchair swaying, and improves safety.

[0005] Some users may prefer a straight-ahead controller, often because they want the most direct control experience, especially when rapid movement or straight-line travel is required. A straight-ahead controller provides a more intuitive feel, allowing users to more easily control the wheelchair's speed and direction.

[0006] Some users may need to flip the armrests for easier entry, exit, or other operations, but a forward-facing controller can cause the armrests to touch the rear wheels during the flipping process, affecting the wheelchair's folding and usability. This problem would be solved if the controller had a rotating function. A rotating controller not only provides greater operational flexibility but also effectively prevents interference between the armrests and the rear wheels, making it easier for users to fold and unfold the wheelchair. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a controller tray holder for wheelchair handles.

[0008] To achieve the objective of this utility model, the technical solution adopted is as follows:

[0009] A controller tray holder for wheelchair handles, comprising:

[0010] An insertion tube, one end of which is inserted into the left or right armrest tube of the wheelchair;

[0011] The other end of the insertion tube is provided with a bracket mounting hole, through which a controller bracket is installed;

[0012] A controller bracket base, wherein a controller bracket plate is provided at the front end of the controller bracket base.

[0013] A handle controller is provided on the controller bracket plate;

[0014] The button lever of the handle controller passes through the button lever mounting hole on the controller bracket and is installed by a limit pin inserted into the button lever limiting hole and a locking nut.

[0015] The limiting pin maintains a relative position with the button lever;

[0016] The controller bracket base is provided with an opening groove at the bottom, through which the upward movement of the limit pin is limited;

[0017] The controller bracket disk and the controller bracket base can rotate or be fixed relative to each other. When the controller bracket disk opening slot is aligned with the limit pin, the button spring at the lower end of the button rod drives the button pin to lock the controller bracket disk and the controller bracket base.

[0018] In a preferred embodiment of this utility model, the controller bracket disk is provided with a plurality of mounting slots.

[0019] In a preferred embodiment of the present invention, the controller bracket plate is mounted on the front end of the controller bracket base by fasteners.

[0020] The beneficial effects of this utility model are as follows:

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following descriptions, well-known structures and technologies have been omitted to avoid unnecessary confusion regarding the concept of this utility model.

[0028] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figure 1-5 The illustrated controller tray 100 for wheelchair handles includes a tube 1, one end of which extends into the left or right armrest tube 2 of the wheelchair. It is tightly engaged with the left or right armrest tube 2 of the wheelchair, thereby ensuring the stability of the entire tray.

[0030] The other end of the insertion tube 1 is provided with a bracket mounting hole 11, through which a controller bracket 3 is provided.

[0031] The front end of the controller bracket base 3 is provided with a controller bracket plate 4, which is installed at the front end of the controller bracket base 3 by fasteners 7.

[0032] This design not only facilitates disassembly and maintenance, but also provides flexible space for the installation of the handle controller 5.

[0033] A handle controller 5 is mounted on the controller bracket plate 4. Specifically, the controller bracket plate 4 has several mounting slots for mounting the handle controller 5.

[0034] The controller bracket plate 4 has several mounting slots, providing multiple options for the installation of the handle controller 5. This allows users to freely adjust the position of the controller according to their personal operating habits or different usage scenarios, thereby optimizing the operating experience.

[0035] The button lever 6 of the handle controller 5 passes through the button lever mounting hole 31 on the controller bracket 3 and is installed by the limit pin 32 inserted into the button lever mounting hole 31 and the locking nut 33, so that the limit pin 32 and the button lever 6 maintain a relative position.

[0036] An opening groove 34 is provided below the controller bracket 3, which limits the upward movement of the limit pin 32.

[0037] The relative position of the limit pin 32 and the button lever 6 is fixed, so that the controller bracket plate 4 can remain stable when it is not operated. When it is necessary to adjust the direction, by pressing down the button lever 6, the relative position between the limit pin 32 and the opening groove 34 below the controller bracket seat 3 changes, realizing the free rotation of the controller bracket plate 4.

[0038] Specifically, it enables relative rotation between the controller bracket plate 4 and the controller bracket seat 3. When the controller bracket plate opening slot 34 is aligned with the limit pin 32, the button spring 61 at the lower end of the button rod 6 drives the button pin 62 to lock the controller bracket plate 4 and the controller bracket seat 3, fixing their relative positions.

[0039] Because of the above structure, the working principle of this utility model is as follows:

[0040] When the user presses down the button lever 6, the entire button lever 6 and the limit pin 32 move down, causing the limit pin 32 to disengage from the opening slot 34 below the controller bracket 3 and the button pin 62 to disengage.

[0041] When the controller bracket plate 4 is freed from the limit and can rotate freely, the button lever 6 is released. When the opening groove 34 under the controller bracket seat 3 rotates to the same direction as the limit pin 32, it can drive the button pin 62 to lock the controller bracket plate 4 to limit its rotation.

[0042] The above shows and describes the basic principles, main features, and advantages of this utility model.

[0043] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of this utility model as defined by the appended claims and their equivalents.
