Description

Technical Field

[0001] This utility model relates to the technical field of electric wheelchair accessories, specifically to a comfort armrest for an electric wheelchair. Background Technology

[0002] Electric wheelchairs are a core mobility tool for people with mobility impairments (such as the elderly and disabled). Their use often involves prolonged and continuous riding. As a key support component of electric wheelchairs, the armrests not only need to support the arms but also often integrate controllers (such as speed adjustment, steering, and mode switching devices). Their comfort, practicality, and safety directly affect the user experience and travel safety.

[0003] Currently, electric wheelchair armrests in the industry generally suffer from the following technical pain points, making it difficult to meet users' long-term needs: Traditional electric wheelchair armrests are mostly made of hard plastic or metal in one piece, with rigid flat / curved contact surfaces and no flexible cushioning structure. When users place their arms on the armrests for extended periods, the contact area between the arm and the armrest can easily cause pressure, and the rigid contact surface can easily lead to skin discomfort. Long-term use may even affect blood circulation in the arm, causing soreness and fatigue. Although some products add simple sponge pads, they are mostly glued on, which is prone to falling off and aging, and cannot adapt to the curved surface of the armrest, resulting in poor fit. Since the controller of electric wheelchairs is mostly installed at the front of the armrest, the wiring harness of existing products is mostly directly exposed on the surface of the armrest or fixed with simple slots for easy wiring. Exposed wiring harnesses are prone to wear and breakage due to daily use, affecting the signal transmission of the controller; at the same time, exposed wiring harnesses detract from the overall aesthetics of the wheelchair.

[0004] In summary, the shortcomings of existing electric wheelchair armrests in terms of comfort and wiring management have become factors restricting the improvement of the user experience of electric wheelchairs. There is an urgent need for an armrest structure that takes into account comfort, wiring concealment, and installation flexibility. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a comfortable armrest for electric wheelchairs. Through a combination of flexible contact pads, anti-detachment wiring harness grooves, and flexible installation structures, it significantly improves comfort, practicality, and safety.

[0006] The technical solution adopted by this utility model is: a comfortable armrest for electric wheelchairs, including an armrest body, a contact surface on the upper surface of the armrest body, and a flexible contact pad arranged along its length on the contact surface; a wire harness groove is provided on the surface of the armrest body away from the contact surface, and the width of the inner side of the wire harness groove is greater than the width of the opening of the wire harness groove.

[0007] In this technical solution, the armrest body is used as a folding armrest on both sides of the electric wheelchair seat. The contact area between the armrest body and the arm is provided with a contact surface. The comfort of the contact area between the arm and the armrest is improved by the contact pad installed on the contact surface. When the controller device of the electric wheelchair is set at the front end of the armrest body, the control harness can pass through the harness groove to achieve hidden wiring. Since the width of the inner side of the harness groove is greater than the width of the opening of the harness groove, the harness can be prevented from falling off after it is inserted. The harness can also be removed under external force, which is convenient for maintenance.

[0008] Preferably, the contact surface of the handrail body is provided with a fitting groove for fitting the contact pad.

[0009] Preferably, the contact pad includes a base plate that snaps into the fitting groove, and the surface of the base plate is covered with a flexible pad.

[0010] Preferably, the handrail body has a plurality of fixing holes for fixing the base plate on the side opposite to the contact surface.

[0011] Preferably, one end of the handrail body is provided with an arc-shaped mounting end, and the other end is provided with a connecting end. The mounting end is provided with a rotating shaft for rotating and mounting the handrail body, and the connecting end is provided with a control mounting plate for mounting a controller.

[0012] Preferably, the mounting end of the handrail body is provided with a socket, one end of the control mounting plate is provided with a plug-in part for inserting into the socket, and a fixing bolt that penetrates the inner wall of the socket is screwed to the bottom of the mounting end.

[0013] Preferably, the control mounting plate has a wire harness opening at one end near the handrail body for the wire harness to pass through.

[0014] The beneficial effects of this utility model are as follows: The contact pad installed on the armrest adopts a composite structure of a rigid base plate and a flexible surface layer. During use, it can disperse the pressure on the arm, reduce local pressure, avoid soreness caused by prolonged use, and improve the comfort of hand support. The wire harness groove allows the wire harness to be naturally limited after being inserted, preventing it from falling off due to daily snagging. The enclosed space inside the groove can protect the wire harness from friction and collision, reducing the probability of controller failure. The control mounting plate is connected to the armrest body without the need for integrated injection molding or disassembly with multiple bolts. The control mounting plate can be pulled out simply by loosening the fixing bolts. It is compatible with different models of controllers. The wire harness opening of the control mounting plate and the wire harness groove are precisely aligned, which can achieve fully concealed wiring of the controller wire harness, further optimizing the appearance and safety; it has high practical value.

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0021] like Figure 1 and Figure 2 As shown in the figure, a specific embodiment of the present invention provides a comfortable armrest for an electric wheelchair, including an armrest body 100. The upper surface of the armrest body 100 is provided with a contact surface, and a flexible contact pad 200 is provided on the contact surface along its length direction. The surface of the armrest body 100 away from the contact surface is provided with a wire harness groove 110, and the width of the inner side of the wire harness groove 110 is greater than the width of the opening of the wire harness groove 110.

[0022] like Figure 1 and Figure 2As shown, with the above configuration, the armrest body 100 in this embodiment is used as a folding armrest on both sides of the electric wheelchair seat. The contact area between the armrest body 100 and the arm is provided with a contact surface. The contact pad 200 installed on the contact surface improves the comfort of the contact area between the arm and the armrest. When the controller device of the electric wheelchair is located at the front end of the armrest body 100, the control harness can pass through the harness groove 110 to achieve hidden wiring. Since the harness groove 110 adopts an inverted trapezoidal / dovetail groove structure with an inner width greater than the opening width, the harness can be naturally limited after being inserted, avoiding detachment caused by daily snagging. At the same time, the enclosed space inside the groove can protect the harness from friction and collision, extending the harness service life by more than 2 times and reducing the probability of controller failure.

[0023] like Figure 1 and Figure 2 As shown, in order to stably install the contact pad 200 on the contact surface of the handrail body 100, this embodiment provides a fitting groove for fitting the contact pad 200 on the contact surface of the handrail body 100. In this way, the contact pad 200 can be stably inserted into the fitting groove, ensuring that there is no gap between the base plate and the fitting groove, and preventing the contact pad 200 from sliding left and right during use.

[0024] like Figure 1 and Figure 2 As shown, the contact pad 200 provided in this embodiment includes a base plate that snaps into the fitting groove, and the surface of the base plate is covered with a flexible pad. Covering the base plate with a flexible pad improves the comfort of the arm contacting the armrest. The composite structure of a rigid base plate and a flexible surface layer (such as slow-rebound memory foam, silicone, etc.) conforms to the arm's curve, dispersing arm pressure, reducing localized pressure, and preventing soreness and swelling caused by prolonged use. Simultaneously, the flexible material has a certain degree of breathability, reducing the problem of sweating and stuffiness in summer and improving comfort in all seasons. Furthermore, the armrest body 100 has several fixing holes 120 on the side opposite to the contact surface for fixing the base plate. Screws can be installed in the fixing holes 120 to fix the base plate, preventing the base plate installed in the contact groove from falling off.

[0025] like Figure 1 and Figure 2As shown, in this embodiment, the armrest body 100 has an arc-shaped mounting end 130 at one end and a connecting end at the other end. The mounting end 130 has a rotating shaft 131 for rotatably mounting the armrest body 100, and the connecting end has a control mounting plate 300 for mounting a controller. Thus, the armrest body 100 is rotatably mounted on both sides of the wheelchair via the rotating shaft 131. The controller mounting plate at the front of the armrest body 100 can mount a wheelchair controller for easy control by the user while riding. In practical applications, the mounting end 130 of the armrest body 100 has a socket, and one end of the control mounting plate 300 has a plug-in portion for inserting into the socket. A fixing bolt 400 penetrating the inner wall of the socket is screwed to the bottom of the mounting end 130. The control mounting plate 300 is connected to the handrail body 100 via a plug and a fixing bolt 400. It does not require one-piece injection molding or disassembly with multiple bolts. The control mounting plate 300 can be pulled out simply by loosening the fixing bolt 400. It is compatible with different types of controllers (such as round and square operation panels). In addition, the end of the control mounting plate 300 near the handrail body 100 is provided with a wire harness opening 310 for the wire harness to pass through. The controller's control wire harness can pass through the wire harness opening 310, which can realize the complete concealment of the controller wire harness, further optimizing the appearance and safety.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
