Description

Technical Field

[0001] This utility model relates to the field of wheelchair-related technology, specifically a novel brushless lightweight electric wheelchair. Background Technology

[0002] A brushless DC motor consists of a motor body and a driver, and is a typical mechatronic product. Because brushless DC motors operate under self-control, they do not require an additional starting winding on the rotor like synchronous motors that start under heavy loads with frequency conversion speed regulation, nor do they experience oscillations or loss of synchronization during sudden load changes. Small and medium-capacity brushless DC motors use permanent magnets. Due to their characteristics of being brushless, having low interference, low noise, smooth operation, long lifespan, and low maintenance costs, brushless motors are widely used in daily life. Electric wheelchairs are upgraded versions of manual wheelchairs by adding a power drive device, controller, battery, and other components. Manually operating the controller allows the wheelchair to perform various functions such as forward, backward, turning, and reclining, providing a convenient and quick way for the elderly and disabled to move around. However, existing electric wheelchairs do not have a back massage function, which can easily lead to discomfort and fatigue after prolonged sitting. Utility Model Content

[0003] To address the shortcomings of existing electric wheelchairs, which lack back massage capabilities and thus cause discomfort and fatigue after prolonged sitting, this invention provides a novel brushless lightweight electric wheelchair.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a novel brushless lightweight electric wheelchair, comprising a downward-facing electric guide rail fixed to the back of the wheelchair backrest frame. The sliding end of the electric guide rail is mounted with a mounting base via a spring seat. The mounting base is mounted with a massage head for massaging the user's back via a fixing frame. The mounting base is equipped with a drive motor for driving the massage head to rotate. Position sensors for detecting the position of the massage head are respectively provided at both ends of the electric guide rail. The wheelchair is also equipped with a controller, and the position sensors, electric guide rail, and drive motor are all electrically connected to the controller.

[0006] As a preferred embodiment of the present invention, the massage head includes a rotating roller, and the surface of the rotating roller is covered with a massage sleeve, and the massage sleeve is provided with a plurality of massage protrusions and a fixing bolt.

[0007] As a preferred embodiment of this utility model, the end of the fixing bolt is provided with a cap corresponding to the outer contour of the massage protrusion.

[0008] As a preferred embodiment of this utility model, the rotating roller is provided with a keyway arranged along the axial direction of the rotating roller, and the massage sleeve is provided with a spline that moves along the keyway.

[0009] As a preferred embodiment of this utility model, the electric guide rails are provided in pairs, a movable plate is provided between the sliding ends of the two electric guide rails, and the mounting base is disposed on the movable plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This novel brushless lightweight electric wheelchair features a backrest massage mechanism that can move up and down, providing a comprehensive massage to the entire back side. This promotes blood circulation and prevents discomfort caused by prolonged sitting. The spring seat ensures elastic contact between the massage head and the user's back, preventing injury. Furthermore, the massage head includes a rotating roller with a massage sleeve covering its surface. The massage sleeve has multiple massage protrusions and fixing bolts. The rotating roller has a keyway along its axial direction, and the massage sleeve has splines that move along the keyway. This allows for adjustment of the massage sleeve's position, facilitating targeted massage of specific areas and providing exceptional flexibility. Attached Figure Description
