Description

Technical Field

[0001] This utility model relates to the field of wheelchair technology, specifically to a wheelchair controller that prevents accidental activation. Background Technology

[0002] Wheelchairs are assistive mobile devices designed for people with limited mobility (such as people with limb disabilities, the elderly, and those recovering from surgery). The core of the wheelchair is the combination of wheel rolling and control system to help users achieve autonomous or assisted movement. It takes into account functionality, comfort and safety, and is a key tool to improve independence in life.

[0003] The wheelchair controller is a core interactive device that integrates operation command input, operation status display and safety control. Its core function is to allow users or caregivers to easily control the movement of the wheelchair, adjust function parameters, and monitor the operation of the equipment in real time. It is a key component to ensure the safe and convenient operation of electric wheelchairs.

[0004] In daily use of wheelchairs, traditional controllers mostly lack a stable, fully enclosed protective structure, easily leading to a chain reaction of "protection failure—accidental touch—safety risk," posing a significant threat to users with mobility impairments. Traditional controllers often rely on simple covers for basic protection, lacking stable limiting structures. When the wheelchair moves (such as over bumpy roads), vibrations occur, and prolonged vibration can cause the cover to fall off, exposing the control panel completely. In this situation, the user's clothing may accidentally touch key buttons on the control panel, such as speed adjustment and steering. Even more dangerously, if others (such as children or caregivers) accidentally touch these buttons, it may directly trigger the wheelchair to start or turn suddenly. Since users are often elderly, disabled, or other people with mobility impairments, their reaction speed is slower, making it difficult to quickly respond to emergencies. They are highly susceptible to falling due to loss of wheelchair control, resulting in fractures, abrasions, and other accidental injuries. Therefore, to address the above problems, a wheelchair controller designed to prevent accidental touches is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a wheelchair controller that prevents accidental activation, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wheelchair controller designed to prevent accidental activation includes a vehicle body. A mounting plate is fixedly connected to the outer side of the armrest of the vehicle body. A control panel is fixedly connected to the top front side of the mounting plate. A closed baffle fixedly connected to the top of the mounting plate is provided on the front side of the control panel. A closed cover is fitted over the outer side of the control panel. An opening and closing assembly is provided on the side of the mounting plate away from the armrest of the vehicle body. The opening and closing assembly includes an adjusting toothed plate fixedly connected to the outer wall of the closed cover and a connecting plate fixedly connected to the outer side of the mounting plate. An adjusting mechanism cooperating with the adjusting toothed plate is provided on the top front side of the connecting plate, and a limiting mechanism cooperating with the adjusting mechanism is provided on the top rear side of the connecting plate.

[0008] As a further optimization of this utility model, the closed baffle is slidably connected to the top of the mounting plate, the closed baffle is hollow inside and open at one end, and the opening of the closed baffle faces the direction of the closed baffle plate.

[0009] As a further optimization of this utility model, the adjusting mechanism includes an adjusting gear rotatably connected to the front top of the mounting plate, the adjusting gear meshing with an adjusting toothed plate, and an adjusting handwheel fixedly connected to the top of the adjusting gear, with the adjusting handwheel and the adjusting gear being coaxially arranged.

[0010] As a further optimization of this utility model, the limiting mechanism includes a limiting support plate fixedly connected to the rear side of the top of the mounting support plate, and a movable support rod extending through the limiting support plate along the length direction of the adjusting gear plate. A movable handle is fixedly connected to the end of the movable support rod away from the adjusting gear.

[0011] As a further optimization of this utility model, the movable support rod is fixedly connected to a limiting tooth block at one end near the adjusting gear, and the limiting tooth block meshes with the adjusting gear.

[0012] As a further optimization of this utility model, a return spring is sleeved on the outer side of the movable support rod. One end of the return spring is fixedly connected to the side wall of the limiting support plate, and the other end of the return spring is fixedly connected to the side wall of the limiting tooth block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this utility model, the adjustment mechanism can precisely drive the closed cover to slide along the mounting plate through the meshing transmission of gears and toothed plates, so as to achieve tight docking or separation of the closed cover and the closed baffle. The structural design of the closed cover being fixedly connected to the closed cover avoids the problem of traditional protective covers being easily lost. Moreover, the opening and closing of the cover can be controlled by turning the handwheel, which is simple and labor-saving to operate and suitable for elderly and disabled users with weak muscle strength. It effectively solves the problems of cumbersome opening and poor adaptability of traditional controllers.

[0015] In this invention, the limiting mechanism can push the limiting tooth block to mesh with the adjusting gear through the reset spring, which can stably lock the position of the adjusting gear and the closed cover. Even if the wheelchair vibrates on a bumpy road, it can prevent the closed cover from accidentally sliding and causing the protection to fail. This automatic reset locking structure ensures that the closed cover always completely covers the control panel, fundamentally avoiding the risk of wheelchair loss of control caused by clothing, debris or other people accidentally touching the button, and significantly improving the safety of the controller against accidental touch.

[0022] 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.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A wheelchair controller designed to prevent accidental activation includes a vehicle body 1. A mounting plate 2 is fixedly connected to the outer side of the armrest of the vehicle body 1. A control panel 3 is fixedly connected to the top front side of the mounting plate 2. A closed baffle 4 is fixedly connected to the top of the mounting plate 2 on the front side of the control panel 3. A closed cover 5 is fitted on the outer side of the control panel 3. An opening and closing assembly 6 is provided on the side of the mounting plate 2 away from the armrest of the vehicle body 1. The opening and closing assembly 6 includes an adjusting toothed plate 61 fixedly connected to the outer wall of the closed cover 5 and a connecting plate 62 fixedly connected to the outer side of the mounting plate 2. An adjusting mechanism 63 is provided on the top front side of the connecting plate 62 to cooperate with the adjusting toothed plate 61. A limiting mechanism 64 is provided on the top rear side of the connecting plate 62 to cooperate with the adjusting mechanism 63.

[0026] It should be noted that: the outer side of the handrail of the vehicle body 1 provides fixed support for the control panel 3 through the mounting plate 2, ensuring the stability of the panel position during operation. The closed baffle 4 and the closed cover 5 work together to completely cover the control panel 3 to prevent accidental external contact. The opening and closing component 6 can flexibly control the opening and closing of the closed cover 5, making it convenient for operators to use the control panel 3 as needed.

[0027] As a further implementation of this solution, the closed cover 5 is slidably connected to the top of the mounting plate 2. The closed cover 5 is hollow inside and open at one end, with the opening of the closed cover 5 facing the closed baffle 4.

[0028] It should be noted that the closed cover 5 moves along the top of the mounting plate 2 through a sliding connection. The design of the opening facing the closed cover 4 allows it to dock with the closed cover 4 when closed, forming a complete closed space. This structure not only ensures the protection against accidental touch of the control panel 3, but also does not affect the smooth movement of the closed cover 5.

[0029] As a further implementation of this solution, the adjustment mechanism 63 includes an adjustment gear 631 that is rotatably connected to the front top of the mounting plate 2. The adjustment gear 631 is meshed with the adjustment gear plate 61. An adjustment handwheel 632 is fixedly connected to the top of the adjustment gear 631, and the adjustment handwheel 632 is coaxially arranged with the adjustment gear 631.

[0030] It should be noted that the adjusting gear 631 of the adjusting mechanism 63 meshes with the adjusting gear plate 61. When the operator rotates the adjusting handwheel 632, the adjusting gear 631 will drive the adjusting gear plate 61 to move, thereby controlling the sliding of the closed cover 5. The adjusting handwheel 632 and the adjusting gear 631 are set on the same axis, which can ensure the precise transmission of rotational power and improve the stability of adjustment.

[0031] As a further implementation of this solution, the limiting mechanism 64 includes a limiting support plate 641 fixedly connected to the rear top of the mounting support plate 2. A movable support rod 642 extends through the limiting support plate 641 along the length of the adjusting gear plate 61. A movable handle 643 is fixedly connected to the end of the movable support rod 642 away from the adjusting gear 631. A limiting tooth block 644 is fixedly connected to the end of the movable support rod 642 near the adjusting gear 631. The limiting tooth block 644 meshes with the adjusting gear 631.

[0032] It should be noted that the movable support rod 642 of the limiting mechanism 64 can move along the limiting support plate 641. Pulling the movable handle 643 can drive the limiting tooth block 644 to disengage from the adjusting gear 631, release the limit, and after being released, the limiting tooth block 644 meshes with the adjusting gear 631, which can fix the position of the adjusting gear 631 and prevent the closed cover 5 from sliding accidentally.

[0033] As a further implementation of this solution, a return spring 645 is sleeved on the outer side of the movable support rod 642. One end of the return spring 645 is fixedly connected to the side wall of the limiting support plate 641, and the other end of the return spring 645 is fixedly connected to the side wall of the limiting tooth block 644.

[0034] It should be noted that the reset spring 645 is sleeved on the outside of the movable support rod 642. Its elasticity can always push the limit tooth block 644 to move towards the adjusting gear 631, ensuring that the limit tooth block 644 and the adjusting gear 631 are tightly meshed. This automatic reset design does not require additional manual operation, which improves the ease of use of the limit mechanism 64.

[0035] Workflow: When the vehicle body 1 is not in use or the operator does not need to adjust the control panel 3, the control panel 3 is in a fully enclosed protective state to prevent accidental external contact. At this time, the closed cover 5 slides along the top of the mounting plate 2 to the closed position. The open end of the closed cover 5 is fully connected with the closed baffle 4 on the front side of the control panel 3, forming an internally hollow closed space that completely encloses the control panel 3. At the same time, the limiting mechanism 64 of the opening and closing component 6 is in a locked state. The return spring 645 pushes the limiting tooth block 644 to mesh tightly with the adjusting gear 631, limiting the rotation of the adjusting gear 631, thereby fixing the position of the adjusting tooth plate 61 and the closed cover 5, preventing the closed cover 5 from accidentally sliding due to wheelchair movement vibration or other external conditions, ensuring that the control panel 3 is always in a closed protective state, and preventing accidental activation of the wheelchair caused by clothing, debris or other people.

[0036] When the operator needs to use the control panel 3, the limit switch must be unlocked and the sealing cover 5 opened via the opening and closing component 6. The operator pulls the movable handle 643 of the limit mechanism 64 by hand. The movable handle 643 drives the movable support rod 642 to slide along the limit support plate 641 away from the adjusting gear 631. The limit tooth block 644 at the end of the movable support rod 642 gradually separates from the adjusting gear 631. At the same time, the return spring 645 is compressed, releasing the rotation restriction on the adjusting gear 631. While maintaining the state of pulling the movable handle 643, the operator uses the other hand to turn clockwise. The adjustment handwheel 632 of the dynamic adjustment mechanism 63 drives the coaxial adjustment gear 631 to rotate synchronously. The adjustment gear 631 meshes with the adjustment toothed plate 61, pushing the adjustment toothed plate 61 to move away from the closed baffle 4. The adjustment toothed plate 61 drives the outer fixed closed cover 5 to slide along the top of the mounting support plate 2. The closed cover 5 gradually separates from the closed baffle 4, exposing the control panel 3 (the exposed area increases with the sliding distance, and the exposed area is 100% when fully opened), meeting the adjustment needs of the operator (such as adjusting the wheelchair speed, steering, etc.).

[0037] When the operator uses the control panel 3, the movable handle 643 can be released, and the position of the closed cover 5 can be fixed by the limiting mechanism 64 to ensure stable operation. After the movable handle 643 is released, the return spring 645 rebounds, pushing the movable support rod 642 and the limiting tooth block 644 to move towards the adjusting gear 631. The limiting tooth block 644 engages with the adjusting gear 631 again, fixing the position of the adjusting gear 631 and the adjusting tooth plate 61, thereby locking the closed cover 5. At this time, the closed cover 5 will not slide due to the operator's arm touching it or the vibration of the wheelchair. The control panel 3 remains in a stable exposed state, and the operator can focus on adjusting the buttons or knobs of the control panel 3, avoiding interference with operation due to the sliding of the cover and improving the safety of use.

[0038] After the operator completes the adjustment of the control panel 3, the closed cover 5 must be closed to restore the anti-accidental touch protection state. Repeat the above unlocking steps, pull the movable handle 643 to separate the limiting tooth block 644 from the adjusting gear 631, release the restriction on the adjusting gear 631, rotate the adjusting handwheel 632 counterclockwise to drive the adjusting gear 631 to rotate in the opposite direction. The adjusting gear 631 pulls the adjusting tooth plate 61 towards the closed cover 4 through meshing transmission. The adjusting tooth plate 61 drives the closed cover 5 to slide along the top of the mounting plate 2 (the sliding direction is opposite to that when it is opened) until the open end of the closed cover 5 is fully connected with the closed cover 4 again. The control panel 3 is completely covered again. Release the movable handle 643, and the return spring 645 pushes the limiting tooth block 644 to mesh and lock with the adjusting gear 631. The position of the closed cover 5 is fixed, and the control panel 3 returns to the fully enclosed anti-accidental touch state, which can cope with subsequent wheelchair movement, storage and other scenarios, and continuously protect the control panel 3.

[0039] 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.
