[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an electric wheelchair controller that is easy to assemble and disassemble, comprising: a controller body 1, a mounting rod 4, a fixing block 7, a quick-release assembly, and a limiting assembly;

[0023] The controller body 1 has a mounting rod 4 fixedly connected to its side wall. A fixing block 7 is provided on the outside of the mounting rod 4. A quick-release component for quick release of the mounting rod 4 is provided inside the fixing block 7. A limiting component for limiting the mounting rod 4 is provided inside the fixing block 7.

[0024] This utility model uses an installation rod 4 to install the controller body 1. The installation rod 4 slides into the interior of the fixing block 7. The fixing block 7 fixes the installation rod 4 at different angles through quick-release components and limiting components, that is, adjusts the angle between the controller body 1 and the seat to meet the usage needs of different users due to differences in hand posture, etc., and improves the comfort of use. The fixing block 7 and the installation rod 4 can be made of aluminum alloy, which is high in strength and light in weight.

[0025] Specifically, the quick-release assembly includes a pivot 5, a rotating rod 6, a sliding groove 8, and an annular groove 9; wherein, the outer side of the mounting rod 4 is connected to the fixing block 7 through two pivots 5, the two pivots 5 are installed through two sliding grooves 8, two symmetrically distributed rotating rods 6 are fixedly connected to the outer side of the mounting rod 4, the two rotating rods 6 are installed inside the fixing block 7 through two annular grooves 9, and the two correspondingly distributed sliding grooves 8 are respectively connected to the two annular grooves 9.

[0026] In the above design, the rotating shaft 5 slides into the interior of the slide groove 8, and the slide groove 8 limits the mounting rod 4 in one direction, so that the mounting rod 4 can only move along the direction of the slide groove 8. When the rotating shaft 5 is fully inserted into the interior of the slide groove 8, the mounting rod 4 is rotated, and the rotating rod 6 slides into the interior of the annular groove 9. As long as the rotating rod 6 is inside the annular groove 9, under the limiting action of the slide groove 8 and the annular groove 9, the mounting rod 4 can only rotate and cannot be separated from the fixing block 7.

[0027] Specifically, the limiting assembly includes limiting rods 11, a movable plate 13, a sliding rod 14, a spring 15, and a fixed shell 16; wherein, the lower end of the fixed block 7 is provided with a plurality of limiting rods 11 arranged in a ring, the lower end of the plurality of limiting rods 11 is fixedly connected to the movable plate 13, the lower end of the movable plate 13 is fixedly connected to the sliding rod 14, the outer side of the sliding rod 14 is provided with a spring 15, the outer side of the sliding rod 14 is slidably connected to the fixed shell 16, the fixed shell 16 is fixedly connected to the fixed block 7, the interior of the fixed block 7 is provided with a plurality of through holes 10 arranged in a ring, the plurality of through holes 10 are slidably connected to the plurality of limiting rods 11 respectively, and the lower end of the mounting rod 4 is provided with a limiting hole 12, the limiting hole 12 is slidably connected to one of the limiting rods 11.

[0028] In the above design, when the device is in normal use, the direction of the mounting rod 4 is perpendicular to the slide groove 8. When the user's hand cannot be kept parallel to the mounting rod 4, that is, the user's hand will bend towards the user's body. The hand generally will not bend away from the user's body, which does not conform to the human body structure. The multiple through holes 10 used to install the limiting rod 11 are all located on the side close to the human body. The limiting hole 12 at the lower end of the mounting rod 4 limits the mounting rod 4 so that the mounting rod 4 can only be fixed at an angle parallel to the handrail or at an angle tilted towards the human body, which is convenient for different users. Moreover, the width of the mounting rod 4 is small. When one limiting rod 11 is inserted into the inside of the limiting hole 12, it will not affect the normal lifting and lowering of other limiting rods 11. The two ends of the spring 15 are fixedly connected to the moving plate 13 and the fixed shell 16, respectively.

[0029] Specifically, the upper part of the controller body 1 is equipped with a control button 2 and a joystick 3. The above design facilitates the control of the electric wheelchair through the control button 2 and the joystick 3.

[0030] Working principle: When installing this utility model, the fixing block 7 is fixedly installed on the armrest of the electric seat. The mounting rod 4 is installed by sliding the rotating shaft 5 into the inside of the sliding groove 8. After the rotating shaft 5 is fully inserted into the inside of the sliding groove 8, the mounting rod 4 is rotated and the rotating rod 6 slides into the inside of the annular groove 9. The rotating rod 6 limits the mounting rod 4.

[0031] When the angle of the controller body 1 needs to be adjusted, the slide bar 14 is pulled out, and the slide bar 14 drives the moving plate 13 to descend. The moving plate 13 compresses the spring 15, and the moving plate 13 drives multiple limit bars 11 to descend. The limit bars 11 disengage from the limit hole 12, releasing the limit on the mounting rod 4, which facilitates the adjustment of the angle of the mounting rod 4. When the slide bar 14 is released, the moving plate 13 is reset under the elastic force of the spring 15. At the same time, the multiple limit bars 11 facilitate the limitation of the mounting rod 4 at different positions. When the user's hand cannot be parallel to the seat armrest, the angle of the controller body 1 is adjusted, and different angles are formed between the controller body 1 and the seat to facilitate use by different users. The electric wheelchair can be easily controlled by the control button 2 and the joystick 3.

[0032] When it is necessary to disassemble the controller body 1, the slide rod 14 is pulled out, and the slide rod 14 drives the moving plate 13 to descend. The moving plate 13 drives multiple limit rods 11 to descend. The limit rods 11 disengage from the limit hole 12, releasing the limit on the mounting rod 4. The mounting rod 4 is rotated to a position parallel to the slide groove 8, and the rotating rod 6 disengages from the annular groove 9, releasing the limit on the mounting rod 4. This allows the rotating shaft 5 to be pulled out from inside the slide groove 8, and the controller body 1 can be disassembled.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
