Utility Model Content

[0003] This disclosure provides a handrail structure and a handcart to at least solve the above-mentioned technical problems existing in the prior art.

[0004] According to a first aspect of this disclosure, a handrail structure is provided, comprising: Handrail brackets are used to secure the handrail to the vehicle body; The armrest body has one end rotatably connected to the armrest bracket via a rotating shaft, allowing the armrest body to rotate about the rotating shaft between an unfolded position and a retracted position; and A locking component, disposed on the armrest bracket and / or the armrest body, is used to releasably lock the armrest body in the unfolded position.

[0005] In one embodiment, the locking component includes a locking member, and the handrail bracket is provided with an engaging portion; The locking element is slidably connected to the handrail body and can move between the locked position and the unlocked position along a preset path; When the locking member is in the locked position, at least a portion of the locking member protrudes and engages with the engaging portion to lock the armrest body in the unfolded position; when the locking member is in the unlocked position, the locking member disengages from the engaging portion, allowing the armrest body to rotate around the rotation axis to the stowed position.

[0006] In one embodiment, a slide rail is provided inside the handrail body, and the locking member is slidably accommodated in the slide rail; The locking assembly also includes an elastic element disposed within the slide rail. The two ends of the elastic element abut against the locking member and the handrail body, respectively, providing the locking member with an elastic force that tends towards the locking position.

[0007] In one embodiment, the locking component further includes a trigger element fixedly disposed on the handrail bracket, the free end of which extends into the sliding path of the locking element; The trigger is configured to receive an external operating force to drive the locking member to move from the locked position to the unlocked position.

[0008] In one embodiment, the trigger includes a connecting portion fixed to the armrest bracket and an elastic arm extending from the connecting portion, the end of the elastic arm constituting the trigger portion; In its natural state, the triggering part is opposite to the locking member, or remains in contact with the locking member and applies pre-pressure.

[0009] In one possible implementation, the locking component includes: An elastic pressing component is provided on the armrest bracket and can switch between an initial state and a compressed deformation state. A retaining post is provided on the side of the elastic pressing component facing the armrest body. A through hole is provided on the handrail bracket for the retaining post to pass through; A locking hole is provided on the armrest body, and when the armrest body is in the unfolded position, the locking hole corresponds to the through hole; When the armrest body is in the unfolded position and the elastic pressing member is in the initial state, the locking post is sequentially inserted into the through hole and the locking hole under the elastic force of the elastic pressing member to achieve locking; When external pressure is applied to the elastic pressing member to cause it to deform, the retaining post exits from the retaining hole and retracts into the through hole or completely exits the through hole to release the lock.

[0019] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0020] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0021] Reference Figure 1 As shown, an exemplary embodiment of the present disclosure discloses an armrest structure including an armrest bracket 1, an armrest body 2, and a locking component 4. The armrest bracket 1 is used to fix to the vehicle body. One end of the armrest body 2 is rotatably connected to the armrest bracket 1 via a rotating shaft 3, so that the armrest body 2 can rotate around the rotating shaft 3 between an unfolded position and a retracted position. The locking component 4 is disposed on the armrest bracket 1 and / or the armrest body 2, and is used to releasably lock the armrest body 2 in the unfolded position.

[0022] In this embodiment, the handrail bracket 1 is the basic supporting component of the entire handrail structure, and its main function is to fix it to the vehicle body. The shape and size of the handrail bracket 1 are designed according to the specific structure of the vehicle body and the installation space. It is usually made of materials with certain strength and rigidity, such as metal alloys or high-strength plastics, to ensure that it will not deform or be damaged when subjected to the pressure of the passenger's arm. The handrail bracket 1 is provided with a shaft hole for mounting the rotating shaft 3. The position and size of the shaft hole match the rotating shaft 3 to ensure that the rotating shaft 3 can be installed smoothly and achieve stable rotation. One end of the handrail body 2 is rotatably connected to the handrail bracket 1 through the rotating shaft 3. This rotatable connection allows the handrail body 2 to rotate freely between the unfolded position and the retracted position around the rotating shaft 3. The shape design of the handrail body 2 conforms to the principles of ergonomics. Its surface is usually covered with a soft material with good friction, such as rubber or leather, to provide a comfortable feel and prevent the arm from slipping. When the armrest body 2 is rotated to the unfolded position, it provides stable support for the passenger's arms. When the armrest is not needed, the armrest body 2 can be rotated to the folded position, reducing its impact on the vehicle's interior space. The locking component 4 has three configuration options: it can be installed only on the armrest bracket 1, only on the armrest body 2, or both on the armrest bracket 1 and the armrest body 2. The core function of the armrest bracket 1 is to releasably lock the armrest body 2 in the unfolded position. Taking the locking component 4 being installed only on the armrest body 2 as an example, an elastic buckle can be installed on the armrest body 2, and a corresponding slot can be installed on the armrest bracket 1. When the armrest body 2 is rotated to the unfolded position, the elastic buckle engages with the slot under its own elasticity, thereby locking the armrest body 2. When the armrest body 2 needs to be folded, the passenger only needs to apply a certain amount of external force to press the elastic buckle, causing it to disengage from the slot, and the armrest body 2 can then be rotated to the folded position. If the locking component 4 is jointly mounted on both the armrest support 1 and the armrest body 2, magnetic elements, such as permanent magnets and ferromagnetic materials, can be installed at corresponding positions on the armrest body 2 and the armrest support 1. When the armrest body 2 is rotated to the unfolded position, the two magnetic elements attract each other, generating sufficient magnetic force to firmly lock the armrest body 2 in the unfolded position. When it is necessary to fold the armrest body 2, the user applies a certain external force to overcome the magnetic force, and the armrest body 2 can be rotated to the folded position.

[0023] In summary, the armrest structure disclosed herein allows for easy switching between the extended and retracted positions of the armrest body 2 through a simple rotation operation. Furthermore, the design of the locking component 4 makes locking and unlocking effortless, requiring no complex steps. Users can lock and release the armrest body 2 with one hand, saving time and effort. The locking component 4 securely locks the armrest body 2 in the extended position, effectively preventing it from wobbling or accidentally retracting during use, providing stable arm support and enhancing riding comfort and safety. When the armrest body 2 is in the retracted position, it minimizes the overall volume of the vehicle body, providing users with more spacious movement. Moreover, since the armrest body 2 is always connected to the armrest bracket 1, it avoids the problem of component loss caused by separate designs, resulting in a compact structure and long service life.

[0024] Reference Figure 1 As shown, in one possible embodiment, the locking component 4 includes a locking member 41, and the armrest bracket 1 is provided with a locking part 111. The locking member 41 is slidably connected to the armrest body 2 and can move between a locked position and an unlocked position along a preset path. Specifically, when the locking member 41 is in the locked position, at least a portion of the locking member 41 protrudes and engages with the locking part 111 to lock the armrest body 2 in the unfolded position; when the locking member 41 is in the unlocked position, the locking member 41 separates from the locking part 111, allowing the armrest body 2 to rotate around the rotation axis 3 to the folded position.

[0025] In this embodiment, the armrest support 1 is also provided with a locking part 111, which cooperates with the locking member 41 in the locking assembly 4 to realize the locking function of the armrest body 2. When the locking member 41 is in the locked position, at least part of the locking member 41 will protrude and engage with the locking part 111 on the armrest support 1. This engagement relationship can effectively prevent the armrest body 2 from rotating around the rotation axis 3, thereby firmly locking the armrest body 2 in the unfolded position and providing stable arm support for the user. For example, the locking member 41 can be a component with a protruding structure. When slid to the locked position, the protruding part is precisely embedded in the corresponding groove of the locking part 111 to achieve reliable locking. When the locking member 41 is in the unlocked position, the locking member 41 separates from the locking part 111. At this time, the armrest body 2 is no longer constrained by the locking member 41 and can freely rotate around the rotation axis 3 to the storage position.

[0026] Specifically, in one embodiment, a slide rail is provided inside the handrail body 2, and the locking member 41 is slidably accommodated in the slide rail. The locking assembly 4 also includes an elastic member disposed in the slide rail, with both ends of the elastic member abutting against the locking member 41 and the handrail body 2 respectively, providing the locking member 41 with an elastic force tending towards the locking position.

[0027] In this embodiment, a slide rail is provided inside the handrail body 2 to facilitate the installation and operation of the locking component 4. The shape and size of the slide rail are designed according to the specifications of the locking member 41 and the elastic member to ensure that the locking member 41 can slide smoothly within it. The locking member 41 is slidably accommodated in the slide rail inside the handrail body 2 and can move between the locked position and the unlocked position along a preset path. When the locking member 41 is in the locked position, at least a portion of the locking member 41 protrudes and engages with the engaging part 111 on the handrail bracket 1, preventing the handrail body 2 from rotating around the rotation axis 3 and locking it in the unfolded position; when the locking member 41 is in the unlocked position, it separates from the engaging part 111, and the handrail body 2 can rotate around the rotation axis 3 to the retracted position. The shape and size of the locking member 41 are adapted to the slide rail and the engaging part 111. For example, a columnar component with a protruding structure can be used, the protruding part being used to engage with the engaging part 111. An elastic element (not shown in the figure) is disposed within the slide rail, with its two ends abutting against the locking element 41 and the handrail body 2, respectively. The elastic element provides the locking element 41 with an elastic force that tends towards the locked position, so that the locking element 41 automatically remains in the locked position when no external force is applied, improving the stability and reliability of the locking. The elastic element can be a spring, such as a compression spring, and its elastic force is selected according to actual needs to ensure sufficient locking force without making the operation too strenuous. When the user needs to use the handrail, he / she holds the handrail body 2 and applies a certain external force to rotate the handrail body 2. The locking element 41 first abuts against the inner wall of the handrail bracket 1, and the locking element 41 slides to the unlocked position against the elastic force of the elastic element. Continuing to apply external force causes the handrail body 2 to rotate around the rotation axis 3 to the unfolded position. When the locking member 41 moves to the engaging part 111, the restoring force of the elastic member causes the locking member 41 to automatically slide to the locked position. At least part of the locking member 41 protrudes and engages with the engaging part 111, locking the armrest body 2 in the unfolded position and providing arm support for the user. When the armrest is not in use, an external force is applied to the locking member 41 to overcome the elastic force of the elastic member, sliding the locking member 41 to the unlocked position, releasing the engagement between the locking member 41 and the engaging part 111. Then, the armrest body 2 is rotated around the rotating axis 3 to the storage position, completing the storage operation.

[0028] Reference Figures 2-4 As shown, in one embodiment, the locking component 4 further includes a trigger 42, which is fixedly mounted on the handrail bracket 1 and has its free end extending into the sliding path of the locking component 41. The trigger 42 is configured to receive an external operating force to drive the locking component 41 from the locked position to the unlocked position.

[0029] In this embodiment, the trigger 42 is fixedly mounted on the handrail bracket 1, with its free end extending into the sliding path of the locking member 41, ensuring that it can touch the locking member 41 when pressed. The trigger 42 has a certain elasticity and can receive external operating force. When the user applies external operating force (such as pressing) to the trigger 42, the trigger 42 will deform, and its free end will push the locking member 41 from the locked position to the unlocked position, thereby realizing the unlocking operation of the handrail. The material of the trigger 42 can be a material with good elasticity and toughness, such as spring steel or elastic plastic. In actual use, when the user needs to use the handrail, he / she holds the handrail body 2 and applies a certain external force to rotate the handrail body 2. The locking member 41 first abuts against the inner wall of the handrail bracket 1, and the locking member 41 slides to the unlocked position against the elastic force of the elastic member. The user continues to apply external force to make the handrail body 2 rotate around the rotation axis 3 to the unfolded position. When the locking member 41 moves to the engaging part 111, the restoring force of the elastic member causes the locking member 41 to automatically slide to the locked position. At least part of the locking member 41 protrudes and engages with the engaging part 111, locking the armrest body 2 in the unfolded position and providing arm support for the user. When the armrest is not in use, the user presses the trigger member 42, which deforms, and its free end pushes the locking member 41 from the locked position to the unlocked position, releasing the engagement between the locking member 41 and the engaging part 111. Then, the armrest body 2 is rotated around the rotation axis 3 to the storage position, completing the storage operation. It is understood that, in the absence of an elastic member in the locking assembly, the engagement between the trigger member 42 and the locking member 41 can also be achieved by two magnetic elements attracting each other. For example, the locking element 41 uses a magnetic element, and the trigger element 42 is also equipped with a magnetic element. When the armrest body 2 is rotated to the rotating position, the trigger element 42 is pressed, so that the trigger element 42 and the locking element 41 attract each other to lock the armrest body 2. When the armrest body 2 needs to be stored, the user applies a certain external force to overcome the magnetic force, and the armrest body 2 can be rotated to the storage position.

[0030] Specifically, refer to Figure 5 As shown, in one embodiment, the trigger 42 includes a connecting portion 421 fixed to the handrail bracket 1 and an elastic arm 422 extending from the connecting portion 421, the end of which constitutes a trigger portion 423. In its natural state, the trigger portion 423 is opposite to the locking member 41, or remains in contact with the locking member 41 and applies pre-pressure.

[0031] In this embodiment, the connecting part 421 is securely fixed to the handrail bracket 1 by welding, bolting, or other methods to ensure that the trigger 42 will not loosen during use. The elastic arm 422 has a certain degree of elasticity and can deform. In its natural state, the trigger part 423 is opposite to the locking member 41, or maintains contact with the locking member 41 and applies pre-pressure. This design allows the elastic arm 422 to deform when the user applies an external operating force (such as pressing) to the trigger part 423, and the trigger part 423 will push the locking member 41 from the locked position to the unlocked position, thereby realizing the unlocking operation of the handrail.

[0032] In one embodiment, the locking component 4 includes an elastic pressing member, a through hole, and a locking hole. The elastic pressing member is disposed on the handrail bracket 1 and switches between an initial state and a compressed deformation state. A retaining post is disposed on the side of the elastic pressing member facing the handrail body 2. The through hole is opened on the handrail bracket 1 for the retaining post to pass through. The locking hole is disposed on the handrail body 2, and when the handrail body 2 is in the unfolded position, the locking hole corresponds to the through hole. Specifically, when the handrail body 2 is in the unfolded position and the elastic pressing member is in the initial state, the retaining post, under the elastic force of the elastic pressing member, sequentially passes through the through hole and the locking hole to achieve locking. When external pressure is applied to the elastic pressing member to cause it to deform, the retaining post exits from the locking hole and retracts into the through hole or completely exits the through hole to release the lock.

[0033] In this embodiment, an elastic pressing member is disposed on the handrail bracket 1, capable of switching between an initial state and a compressed deformation state. It is typically made of an elastic material, such as spring steel or elastic plastic. A retaining post is provided on the side of the elastic pressing member facing the handrail body 2. The shape and size of the retaining post are adapted to the through hole and the locking hole, and it is generally cylindrical. In the initial state, the elastic pressing member uses its own elasticity to hold the retaining post in a specific position; when subjected to external pressure, the elastic pressing member deforms, causing the retaining post to move. The through hole is opened on the handrail bracket 1, and its position and size must ensure that the retaining post can pass through smoothly. The diameter of the through hole is slightly larger than the diameter of the retaining post to ensure that the retaining post does not encounter excessive resistance during passage, while also ensuring the stability of the retaining. The locking hole is disposed on the handrail body 2, and when the handrail body 2 is in the unfolded position, the locking hole corresponds to the through hole. The shape and size of the locking hole match the retaining post, allowing the retaining post to be accurately inserted into it, thereby locking the handrail body 2. When the armrest body 2 is in the unfolded position and the elastic pressing component is in its initial state, the retaining pin, under the elastic force of the elastic pressing component, sequentially passes through the through hole and the locking hole. At this time, the armrest body 2 is firmly locked and cannot rotate around the rotation axis 3, providing stable arm support for the user. When external pressure is applied to the elastic pressing component to induce deformation, the elastic pressing component compresses or bends, causing the retaining pin to exit from the locking hole and retract into the through hole or completely exit the through hole, thereby releasing the lock on the armrest body 2 and allowing the armrest body 2 to rotate around the rotation axis 3 to the retracted position. It can be understood that the overall shape of the elastic pressing component is similar to the aforementioned trigger 42, and therefore can be combined with... Figure 5 To understand.

[0034] In one embodiment, the handrail support 1 includes a handrail support bracket 11 and a connecting bracket 12 connected to each other. The handrail support bracket 11 is rotatably connected to the handrail body 2, and the connecting bracket 12 is configured to be fixedly connected to the vehicle body.

[0035] In this embodiment, the handrail support bracket 11 is the part that is directly and rotatably connected to the handrail body 2. It is typically made of a material with a certain strength and rigidity, such as aluminum alloy or high-strength plastic. Its shape design is optimized according to the rotation requirements and spatial layout of the handrail body 2. The connecting bracket 12 connects the handrail structure to the vehicle body. It is usually designed according to the structure of the vehicle body and the installation space, and its shape and size match the installation location on the vehicle body. The connecting bracket 12 can be made by stamping or casting metal sheets to ensure that it has sufficient strength and rigidity.

[0036] In one embodiment, a silicone pad is provided at the connection between the handrail bracket 1 and the handrail body 2.

[0037] In this embodiment, a silicone pad is disposed at the connection point between the armrest bracket 1 and the armrest body 2, specifically on the surface area where the armrest bracket 1 and the armrest body 2 directly contact each other. It can completely cover the connection portion 421, or be designed into a specific shape and size according to actual needs to achieve optimal cushioning and shock absorption. Furthermore, the surface of the silicone pad can be provided with fine textures or protrusions to increase the friction between it and the armrest body 2, further preventing the armrest body 2 from sliding during use.

[0038] In one embodiment, a plug 121 is installed at the end of the connecting bracket 12 furthest from the handrail support bracket 11. This plug completely seals the port of the connecting bracket 12, preventing external substances from entering. The plug 121 is made of a material with a certain degree of elasticity and toughness, such as rubber or plastic. A rubber plug 121 has good sealing and elasticity, allowing it to fit tightly against the port of the connecting bracket 12, effectively preventing dust and debris from entering. Furthermore, it can elastically deform under certain external force, making it less prone to damage. A plastic plug 121 has advantages such as light weight, low cost, and ease of processing and molding, while also meeting basic sealing and protection requirements.

[0039] This disclosure also provides a handcart including the armrest structure in any of the above-described embodiments.

[0040] In this embodiment, the trolley mainly includes a body, wheels, and a handrail structure. The size and shape of the handrail structure are determined according to the size and design requirements of the body. Because the trolley of this disclosure includes the handrail structure described in any of the above embodiments, the handrail body 2 can be switched between the unfolded and folded positions through a simple rotation operation. Furthermore, the design of the locking component 4 makes locking and unlocking easy and effortless, requiring no complicated steps. Users can lock and release the handrail body 2 with one hand, saving time and effort. The locking component 4 securely locks the handrail body 2 in the unfolded position, effectively preventing it from wobbling or being accidentally folded during use, providing stable arm support for the user and improving riding comfort and safety. When the handrail body 2 is in the folded position, it minimizes the overall volume of the trolley, providing users with more spacious activity space. Since the handrail body 2 is always connected to the handrail bracket 1, it avoids the problem of component loss caused by a separate design, resulting in a compact structure and long service life.
