[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4, a wheelchair controller with a protective mechanism, comprising a base 1, an elastic member, a controller body 8, and a protective assembly, the base 1 being in an inverted L-shape, the controller body 8 being embedded above the base 1, the elastic member being arranged above the bottom wall near the wheelchair backrest below the base 1, the protective assembly comprising a lower pressure plate 2, a connecting plate 3, a rack 4, a gear 5, a hinge shaft 6 and a cover plate 7, the upper and lower ends of the elastic member being respectively connected to the base 1 and the lower pressure plate 2, the lower pressure plate 2 being provided with an L-shaped connecting plate 3 on one side close to the side wall of the base 1, the rack 4 being arranged above one end of the connecting plate 3 away from the lower pressure plate 2, the base 1 being further provided with a hinge shaft 6 hinged to the cover plate 7, the inner side of the cover plate 7 being adapted to the controller body 8, and the outer side of the cover plate 7 being provided with a gear 5 meshing with the rack 4.

[0023] During actual use, the base 1 is fixed on the side wall of the wheelchair. Initially, the lower pressure plate 2 is in a higher position supported by the elastic member. At this time, the cover plate 7 is closed on the controller body 8. When the arm presses down the lower pressure plate 2 until it is level with the controller body 8, the lower pressure plate 2 drives the rack 4 to move through the connecting plate 3. Driven by the rack 4, the gear 5 causes the cover plate 7 to rotate on the hinge shaft 6. At this time, the buttons of the controller body 8 can be driven by hand.

[0024] In this embodiment, in order to ensure the stability of the operation of the lower pressure plate 2, the elastic member includes a spring 9 and a telescopic rod 10, and the spring 9 is sleeved on the telescopic rod 10. The upper and lower ends of the spring 9 and the telescopic rod 10 are respectively connected to the lower pressure plate 2 and the base 1. According to needs, several groups of elastic members can be set.

[0025] If the arm directly contacts the lower pressure plate 2, it is easy for it to hit the human body. For this reason, a buffer pad 11 is arranged above the lower pressure plate 2, a first Velcro is arranged above the lower pressure plate 2, and a second Velcro bonded to the first Velcro is arranged below the buffer pad 11. The cover plate 7 is elastic and made of transparent material. The cover plate 7, the lower pressure plate 2 and the device body are all detachably connected, and it also has a water-proof effect, and is easy to use.
