Description

Technical Field

[0001] This application relates to the field of wheelchair equipment technology, and in particular to an anti-loss structure for an external light for a wheelchair controller. Background Technology

[0002] Wheelchairs are an important tool for patient rehabilitation and a vital means of transportation for people with limb disabilities. Electric wheelchairs are upgraded from traditional wheelchairs by adding components such as a power unit, battery, and controller, transforming them into intelligent wheelchairs capable of autonomous movement. Their main control is achieved through a controller installed on the wheelchair armrest, which can be equipped with external lights. However, existing controllers typically use external lights that are directly plugged into and unplugged from the wheelchair, making them prone to being lost in case of accidents. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this application provides an anti-loss structure for an external light connected to a wheelchair controller, thereby solving the problems existing in related technologies. The technical solution is as follows:

[0004] This application provides an anti-loss structure for an external light connected to a wheelchair controller, comprising: an external light, the external light including a light housing; and a connector, one end of which has a first connecting component for connecting to the light housing, and the other end of which has a second connecting component for fixedly connecting to the wheelchair; wherein, the light housing has a connecting portion for mounting the first connecting component. The first connecting component at one end of the connector connects to the external light, and the second connecting component at the other end of the connector is fixedly connected to the wheelchair, so that even when the external light is unplugged, a stable connection can still be maintained with the wheelchair, preventing the external light from detaching from the wheelchair and avoiding the loss of the external light.

[0005] In one embodiment, the connecting part is rotatably mounted on the lamp housing. The connecting part and the external lamp can rotate relative to each other, allowing the external lamp to rotate freely around the axis of the connecting part, preventing the connecting part from twisting during use.

[0006] In one embodiment, the connecting portion is located below the center of gravity of the lamp housing. This lower positioning improves the suspension stability of the connecting component.

[0007] In one embodiment, the first connecting component includes a buckle, and a slot is provided on the connecting portion. The buckle and the slot are correspondingly adapted to engage and connect. The engaging connection allows the first connecting component to be stably installed and fixed on the connecting portion.

[0008] In one embodiment, the first connecting assembly includes a rope body, and a mounting rod is disposed on the connecting portion, with the rope body wound around the mounting rod. The rope-rod connection allows the first connecting assembly to be stably installed and fixed on the connecting portion.

[0009] In one embodiment, the second connection component includes straps for securing the connector to the wheelchair. Securing the connector to the wheelchair with the straps prevents the connector from detaching from the wheelchair.

[0010] In one embodiment, the second connecting component includes a length adjustment buckle for adjusting the effective usable length of the connector. The length adjustment buckle controls the effective usable length of the connector, making it suitable for wheelchairs of different sizes.

[0011] In one embodiment, an anti-slip sleeve and / or a soft covering layer are provided on the second connecting component. The anti-slip sleeve and soft covering layer can prevent the connecting component from slipping on the wheelchair.

[0012] In one embodiment, the external lamp includes a lamp body, and the lamp housing has a receiving cavity, within which the lamp body is detachably disposed. The lamp body can be detached from the lamp housing, making it more flexible to use.

[0013] In one embodiment, the connecting part is disposed below the lamp housing relative to the lamp body, which can prevent the connecting part from interfering with or affecting the illumination of the lamp body.

[0014] The advantages or beneficial effects of the above technical solutions include at least the following:

[0015] In this application, the connector has a first connecting component and a second connecting component at both ends. The first connecting component is connected to an external light, and the second connecting component is fixedly connected to the wheelchair. The external light is connected to the wheelchair through the connector, so that the external light remains connected to the wheelchair even after it is unplugged, preventing loss.

[0016] The above overview is for illustrative purposes only and is not intended to be limiting in any way.

[0022] In the following description, only certain exemplary embodiments are briefly described to make the objectives, features, and advantages of this invention more apparent. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, this utility model provides an anti-loss structure for an external light for a wheelchair controller, comprising: an external light 100, the external light 100 including a light housing 101; a connector 200, one end of the connector 200 being provided with a first connecting component 201 for connecting to the light housing 101, and the other end being provided with a second connecting component 202 for fixedly connecting to a wheelchair 500; wherein, the light housing 101 is provided with a connecting portion 300 for mounting the first connecting component 201.

[0025] In this embodiment, the connector 200 can adopt a hanging rope structure. In other embodiments, the connector 200 can also adopt other connection structures, such as a connecting strap. A connecting part 300 is provided on the lamp housing 101. A first connecting component 201 and a second connecting component 202 are respectively provided at both ends of the connector 200. The first connecting component 201 is installed and fixed on the connecting part 300 of the lamp housing 101, and the second connecting component 202 is installed and fixed on the wheelchair 500. The external lamp 100 is connected to the wheelchair 500 through the connector 200, so that the external lamp 100 can still maintain a stable connection with the wheelchair 500 after being unplugged, preventing the external lamp 100 from falling off the wheelchair 500 and thus preventing loss.

[0026] The wheelchair controller is fixed to the wheelchair armrest. The external light 100 is electrically connected to the wheelchair controller through a plug-in connection. The external light 100 is connected to the wheelchair 500 by a lanyard. There is no need to authenticate the wheelchair controller and the external light 100 simultaneously, which saves costs.

[0027] It should be noted that the fixed connection in the embodiments of this application can be a detachable connection such as a plug-in or snap-in connection, or it can be a non-detachable connection.

[0028] The connecting part 300 is rotatably mounted on the lamp housing 101.

[0029] A rotary bearing can be provided between the connecting part 300 and the lamp housing 101, so that the connecting part 300 is rotatably mounted on the lamp housing 101. The first connecting component 201 of the connector 200 is fixedly mounted on the connecting part 300. The connecting part 300 and the lamp housing 101 can rotate relative to each other, so that the external lamp 100 can rotate freely 360° around the axis of the connector 200. When the external lamp 100 is twisted or rotated during use, the relative rotation between the connecting part 300 and the lamp housing 101 can prevent the connector 200 from twisting during use, making the use of the external lamp 100 more stable and reliable.

[0030] The connecting part 300 is located below the center of gravity of the lamp housing 101.

[0031] The connecting part 300 is positioned below the center of gravity of the lamp housing 101, which improves the suspension stability of the connecting part 200 when it is connected to the external lamp 100. The surface of the connecting part 300 can have a frosted texture, which increases the friction between the first connecting component 201 of the connecting part 200 and the connecting part 300, thereby preventing relative slippage and making the external lamp 100 more stable and reliable in use.

[0032] The first connecting component 201 includes a buckle, and a slot is provided on the connecting part 300. The buckle and the slot are adapted to engage and connect.

[0033] The first connecting component 201 adopts a snap-fit ​​structure, such as a ring snap-fit ​​or a plug-in snap-fit. A slot corresponding to the snap-fit ​​structure is provided on the connecting part 300. The snap-fit ​​structure and the slot are engaged and connected, so that the first connecting component 201 can be stably installed and fixed on the connecting part 300, preventing the connecting component 200 from detaching from the external lamp 100.

[0034] The first connecting component 201 includes a rope body, and an mounting rod is provided on the connecting part 300, with the rope body wound around the mounting rod.

[0035] The first connecting component 201 adopts a common rope structure, such as nylon rope or fiber rope. An installation rod is provided on the connecting part 300. After the rope passes around the installation rod, it is knotted and fixed on the installation rod, so that the first connecting component 201 can be stably installed and fixed on the connecting part 300, preventing the connecting component 200 from detaching from the external lamp 100.

[0036] The second connection component 202 includes straps for securing the connector 200 to the wheelchair 500.

[0037] The second connecting component 202 uses a strap, which can be made of canvas straps, nylon rope straps, or other different strap structures. The straps fix the connector 200 to the wheelchair 500, preventing the connector 200 from falling off the wheelchair 500 and thus ensuring the anti-loss effect of the external light 100.

[0038] The second connecting component 202 includes a length adjustment buckle 400 for adjusting the effective working length of the connecting member 200.

[0039] The second connecting component 202 includes a length adjustment buckle 400. The length adjustment buckle 400 can be an adjustment buckle structure such as a spring rope buckle. The length of the connector 200 can be increased or decreased by adjusting the length of the connector 200, thereby controlling the effective length of the connector 200 on the wheelchair 500, so that the connector 200 can be used on wheelchairs 500 of different sizes, making it more flexible and convenient to use.

[0040] An anti-slip sleeve and / or a soft covering layer are provided on the second connecting component 202.

[0041] An anti-slip sleeve or soft covering layer is provided on the second connecting component 202 to prevent the connector 200 from slipping on the wheelchair 500, making the connection between the connector 200 and the wheelchair 500 more stable.

[0042] The external lamp 100 includes a lamp body 102, and the lamp housing 101 has a receiving cavity, and the lamp body 102 is detachably disposed in the receiving cavity.

[0043] The lamp housing 101 covers the outside of the lamp body 102. The lamp housing 101 and the lamp body 102 together form the external lamp 100 structure. The lamp body 102 is detachably installed in the receiving cavity of the lamp housing 101, so that the lamp body 102 can be removed from the lamp housing 101. After separation, it is convenient for cleaning, maintenance or replacement of the lamp body 102, and the use of the external lamp 100 is more flexible.

[0044] The connecting part 300 is disposed below the lamp housing 101 relative to the lamp body 102.

[0045] The connecting part 300 is located below the lamp housing 101, and the connecting part 300 is located on the lamp housing 101 on the side opposite to the lamp body 102, specifically on the side closer to the wheelchair. With the above installation method, the connecting part 100 will not pass under the lamp body 102, thereby avoiding interference or influence on the illumination of the external lamp 100 by the connecting part 100, and making it more practical.
