Description

Technical Field

[0001] This utility model relates to the field of electric wheelchair technology, and in particular to an electric wheelchair controller with anti-slip grips. Background Technology

[0002] An electric wheelchair is a type of wheelchair powered by electricity, designed to help people with mobility limitations perform their daily activities more easily and independently. Electric wheelchairs are typically equipped with easy-to-use control levers or buttons, allowing users to move forward, backward, and turn with simple controls. Modern electric wheelchair control systems are generally designed to be intuitive and suitable for all types of users.

[0003] However, most traditional electric wheelchair controllers do not have a non-slip grip on the joystick handle, which makes it difficult for users to hold the handle securely, especially in wet or sweaty conditions. This increases the risk of accidental slippage. Furthermore, the poor non-slip properties mean that users may need to use more force to keep the joystick in place, leading to hand fatigue and potentially causing discomfort or pain with prolonged use.

[0004] Therefore, those skilled in the art have provided an electric wheelchair controller with a non-slip grip to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electric wheelchair controller with an anti-slip grip. Compared to most traditional electric wheelchair controllers, this controller features a rocker mechanism. By fixing a positioning plate to the control base, an elastic anti-slip sleeve can be fitted onto the outside of the rocker handle. This sleeve effectively increases the friction of the rocker handle, preventing the user's hand from slipping during use, improving operational stability and safety, providing a better grip, reducing hand fatigue and discomfort from prolonged use, and further protecting the surface of the rocker handle from wear and scratches caused by friction or collision. The easily detachable structure allows for quick replacement of the elastic anti-slip sleeve on the rocker mechanism.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An electric wheelchair controller with a non-slip grip includes a wheelchair handle. A placement groove is provided at the front end of the upper surface of the wheelchair handle. An adjustment mechanism is provided on the inner bottom surface of the placement groove. The adjustment mechanism includes a limiting slider. An adjustment seat is slidably connected to the outer wall of the limiting slider. A limiting groove is provided in the middle of the lower surface of the adjustment seat. A positioning block is fixedly connected to the middle of the inner top surface of the limiting groove. Multiple locking grooves are provided on the inner walls of both sides of the limiting groove. The inner walls of the locking grooves engage with the limiting blocks.

[0008] A control seat is slidably connected inside the placement slot. A rocker mechanism is provided on the upper surface of the control seat. The rocker mechanism includes a positioning slot. A positioning plate is fixedly connected to the inner bottom surface of the positioning slot. A corrugated rubber is fixedly connected to the middle of the upper surface of the positioning plate. An elastic anti-slip sleeve is fixedly connected to the middle of the upper surface of the corrugated rubber.

[0009] Compared with most traditional electric wheelchair controllers, this electric wheelchair controller is equipped with an adjustment mechanism. By rotating the locking bolt, the limit of the control seat is opened, allowing the user to move the adjustment seat in the placement slot. This allows the user to adjust the position of the electric wheelchair controller according to their needs, thereby improving the comfort of using the electric wheelchair controller.

[0010] Furthermore, multiple limiting slots are provided on the outer walls of both sides of the limiting slider, and the limiting block engages with the limiting slots.

[0011] The above technical solution enables the control seat to move a distance that can be limited and differentiated.

[0012] Furthermore, the limiting slider is fixedly connected to the center of the bottom surface of the placement groove;

[0013] The above technical solution enables the adjustment seat to move within the placement slot.

[0014] Furthermore, a positioning groove is provided in the middle of the upper surface of the limiting slider, and the positioning block is slidably connected to the positioning groove;

[0015] The above technical solution improves the stability of the adjustment seat moving on the limit slider.

[0016] Furthermore, a locking bolt is threaded into the center of the lower surface of the positioning block;

[0017] The above technical solution locks the position of the positioning block in the positioning groove by setting a locking bolt, thereby locking the position of the control seat.

[0018] Furthermore, a fixing groove is provided on the outer wall of one side of the limiting block, and a spring is fixedly connected to the inner wall of the fixing groove;

[0019] The above technical solution enables the limiting block to return to its original position under the action of the spring.

[0020] Furthermore, the positioning groove is formed at the rear end of the upper surface of the control base;

[0021] The above technical solution allows users to easily disassemble the positioning plate inside the positioning slot.

[0022] Furthermore, a connecting seat is fixedly connected to the center of the bottom surface of the positioning groove, and a rocker handle is provided at the center of the upper surface of the connecting seat;

[0023] The above technical solution enables users to control the position of the electric wheelchair via the joystick handle and connecting seat.
