Description

Technical Field

[0001] This utility model relates to the field of electric wheelchair technology, and in particular to a spherical handle controller for an electric wheelchair. Background Technology

[0002] An electric wheelchair is a power-driven wheelchair designed to help people with mobility impairments move more easily. Unlike traditional manual wheelchairs, electric wheelchairs are equipped with an electric motor and control system, allowing users to easily control the direction and speed using joysticks or buttons. This design not only enhances the user's independence but also provides greater flexibility and comfort in various environments.

[0003] However, the handle controller of traditional electric wheelchairs is mostly made of one piece, which makes it impossible to store the handle controller as needed when not in use or during transportation. This makes the handle controller less safe during transportation or when not in use and easily damaged by external factors.

[0004] Therefore, those skilled in the art have provided a spherical handle controller for an electric wheelchair 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 a spherical handle controller for electric wheelchairs. This handle controller is equipped with a rocker mechanism. Users can press a control button as needed to retract the control seat into a flip-top seat using an electric telescopic rod. Then, under the action of gear meshing, a servo motor flips the flip-top seat, thereby retracting and storing the rocker handle inside the seat. This reduces the risk of damage to the rocker handle from external sources, thus improving the safety of the handle controller during transport and storage.

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

[0007] A spherical handle controller for an electric wheelchair includes a wheelchair armrest. A placement seat is fixedly connected to the middle of the upper surface of the armrest. A rocker mechanism is provided at the front end of the upper surface of the placement seat. The rocker mechanism includes a placement slot and a control button. A servo motor is fixedly connected to the lower part of the inner wall of the rear end of the placement slot. A flip seat is rotatably connected to the inner wall of the front end of the placement slot. A rotating block is fixedly connected to the outer wall of the rear end of the flip seat. A storage slot is provided in the middle of the upper surface of the flip seat. An electric telescopic rod is fixedly connected to the upper part of the inner wall of the rear end of the storage slot. A support rod is hinged to the output end of the electric telescopic rod. A control seat is rotatably connected to the upper end of the inner wall of the storage slot. A padding mechanism is provided at the rear end of the upper surface of the placement seat. The padding mechanism includes a limiting slide groove and a protective pad.

[0008] Through the above technical solution, the handle controller is equipped with a protective pad mechanism, which allows the user to slide to shield and protect the rocker arm mechanism, thereby further reducing the damage to the rocker arm handle from external sources and improving the safety of the electric wheelchair during storage and transportation.

[0009] Furthermore, the placement slot is formed at the front end of the upper surface of the placement base;

[0010] The above technical solution enables the rocker arm mechanism to be installed on the mounting base.

[0011] Furthermore, a drive gear is fixedly connected to the output end of the servo motor, and an adjustment gear is fixedly connected to the front end of the outer wall of the rotating block, wherein the drive gear meshes with the adjustment gear;

[0012] The above technical solution enables the servo motor to control the rotating block to flip or reset its angle through gear meshing.

[0013] Furthermore, the control button is fixedly connected to one side of the front end of the upper surface of the placement base;

[0014] The above technical solution enables users to control the joystick mechanism to close or open via control buttons.

[0015] Furthermore, the support rod is hinged to the control seat away from the electric telescopic rod;

[0016] The above technical solution enables the electric telescopic pole to store and deploy the control base via the support rod.

[0017] Furthermore, a rocker handle is provided in the middle of the upper surface of the control base;

[0018] The above technical solution enables users to operate the electric wheelchair by setting up a joystick handle.

[0019] Furthermore, the protective pad is slidably connected to the upper surface of the placement base;

[0020] The above technical solution enables users to open and close the rocker mechanism by sliding the protective pad.

[0021] Furthermore, the limiting groove is formed at the rear end of the upper surface of the placement seat, and the inner wall of the limiting groove is slidably connected to a limiting slider.

[0022] The above technical solution enables the limiting slider to slide relatively smoothly within the limiting groove.

Compared with most traditional handle controllers, this handle controller is equipped with a rocker mechanism. The user can press the control button as needed to make the electric telescopic rod retract the control seat into the flip seat. Then, under the action of gear meshing, the servo motor flips the flip seat, thereby retracting and storing the rocker handle inside the placement seat, reducing the rocker handle from external damage, and thus improving the safety of the handle controller when moving and storing it.
