Description

Technical Field

[0001] The utility model relates to the technical field of wheelchair controllers, in particular to a wheelchair controller with a quick installation mechanism. Background Art

[0002] The electric wheelchair controller is one of the core components of the electric wheelchair. It is a device that controls the electric wheelchair's forward, backward, turning, braking and other functions. However, when the electric wheelchair is in use, in addition to the operator operating the controller, it often requires others to push the wheelchair from behind to operate it. Therefore, a controller is also required at the push handle at the rear of the wheelchair, but this increases the production cost. In order to be firm, the existing controllers are usually troublesome to install, and it is even more time-consuming to disassemble and install them when changing their position. Now, there is a need for a controller that can be quickly installed, disassembled and changed in position. To address the above problems, the present application designs a wheelchair controller with a quick installation mechanism. Utility Model Content

The other end of the three springs 20 is fixed on the first slide groove 16, and a button 21 is slidably connected to the top of the controller body 12. The button 21 passes through the controller body 12, and a lifting block 22 is fixed to the bottom end of the button 21. A plurality of connecting rods 23 are fixed to the bottom end of the lifting block 22, and a lifting rod 24 is fixed to the bottom end of the plurality of connecting rods 23. Both ends of the lifting rod 24 are rotatably connected to a second rotating wheel 25, and the second rotating wheel 25 contacts the two first rotating wheels 19 on the same side. A rocker 26 and a plurality of function buttons 27 are installed at the top of the controller body 12.

[0022] When the present wheelchair controller is in use, when the controller body 12 is installed, in the initial state, the card block 6 drives the card block 10 to pass through the mounting seat 4 under the action of the spring, and the controller body 12 is located directly above the mounting seat 4 and pressed downward, and the controller body 12 squeezes the card block 10, and the top of the card block 10 is set as an inclined surface. Under the action of force, the card block 10 is squeezed into the inside of the mounting seat 4, the first spring 8 is compressed, and the second spring 9 is stretched. When the slot 13 drops to the position of the card block 10, under the action of the first spring 8 and the second spring 9, the card block 6 drives the card block 10 to pass through the mounting seat 4 again, and the card block 10 is inserted into the slot 13 to complete the fixed installation. When disassembling, press the button 21, the button 21 drives the lifting block 22 to move downward, and the lifting block 22 drives the connecting rod 23 The lifting rod 24 moves downward, and the lifting rod 24 drives the two second wheels 25 to move downward. The second wheels 25 contact the first wheel 19, and under the action of force, squeeze the first wheel 19 to slide outward along the first slide groove 16. The first wheel 19 drives the rotating shaft 18 and the rotating block 17 to move outward, and the third spring 20 is stretched. The first wheel 19 partially slides out of the transparent slide groove 15. The arc-shaped slide groove 11 on the block 10 corresponds to the position of the first wheel 19. The first wheel 19 squeezes the block 10 to both sides and pulls the controller body 12 upward through the hand-holding groove 14. Under the action of the arc-shaped slide groove 11 and the first wheel 19, the block 10 is separated from the slot 13, so that the controller body 12 is separated from the mounting seat 4, and the installation steps are repeated to be installed on the mounting seat 4 at other positions.

[0023] In actual use, it is found that there is friction between the first rotating wheel 19 and the second rotating wheel 25, which affects the effect of the second rotating wheel 25 squeezing the first rotating wheel 19. In order to solve the above problem, in this embodiment, a plurality of spherical grooves 28 are opened on the outer wall of the second rotating wheel 25, and a ball 29 is rotatably connected in the spherical groove 28.

[0024] It is found in actual use that the lifting block 22 will be offset when moving up and down. In order to avoid the above problem, in this embodiment, a plurality of limit columns 30 are evenly fixed inside the controller body 12. The limit columns 30 pass through the lifting block 22, and the lifting block 22 is slidably connected to the limit columns 30.

[0025] It is found in actual use that the controller body 12 may slide when installed on the mounting base 4. To avoid the above problem, in this embodiment, an insert block 31 is fixed to the top of the mounting base 4, and a slot 32 adapted to the insert block 31 is provided at the bottom of the controller body 12.

[0026] It is found that during actual use, the operator may bump into the concave mounting block 5 . In order to protect the operator, in this embodiment, a protective pad 33 is fixed to the top of the concave mounting block 5 .

[0027] It is found in actual use that slipping may occur when operating the rocker 26. To avoid the above problem, in this embodiment, an anti-slip sleeve 34 is provided on the rocker 26. The anti-slip sleeve 34 is made of rubber.
