Technical Field

[0001] This application relates to the field of guardrail structure design, and more particularly to a movable handrail for vehicles. Background Technology

[0002] To facilitate barrier-free travel for people with disabilities, buses now have designated wheelchair areas. Currently, there are two types of guardrail structures for these wheelchair areas: fixed installation and a complex spring-loaded structure. With the fixed installation, standing passengers find it difficult to access the wheelchair area when no one is using it, and it also affects the passageway within the bus. The complex structure of the fixed installation makes both installation and use inconvenient.

[0003] Therefore, there is an urgent need for a handrail that is easy to install and has a simple structure to solve the above problems. Utility Model Content

[0004] This application provides a movable handrail for vehicles to solve the problems mentioned in the background art, such as inconsistent installation, complex structure, and inconvenient use.

The multiple positioning grooves are spaced apart in the circumferential direction of the rotating sleeve. The elastic positioning component can extend into the positioning groove to realize the positioning between the positioning shaft and the rotating sleeve. One end of the handrail body is connected to the rotating sleeve.

[0010] Preferably, the mounting assembly includes a first mounting portion and a second mounting portion; the first mounting portion is provided with a first receiving groove; the second mounting portion is provided with a second receiving groove, and the first receiving groove and the second receiving groove are connected to form a clamping hole for wrapping on an external structure; the first mounting portion and the second mounting portion are detachably connected; and a positioning shaft is provided on the first mounting portion.

[0011] Preferably, the cross-sectional shape of the first receiving groove and the second receiving groove is semi-circular, and the first receiving groove and the second receiving groove are connected to form a circular clamping hole.

[0012] Preferably, the first mounting part and the second mounting part are detachably connected by a first screw.

[0013] Preferably, the positioning shaft is fixedly connected to the mounting assembly by a second screw.

[0014] Preferably, the elastic positioning component includes multiple elastic positioning beads, which are spaced apart on the positioning shaft; the length direction of the positioning groove is configured to be the axial direction of the rotating sleeve, so that all the elastic positioning beads of the elastic positioning component can be inserted into the same positioning groove.

[0015] Preferably, multiple elastic positioning components are arranged at 90-degree intervals along the circumferential direction of the positioning axis, and multiple positioning grooves are arranged at 90-degree intervals along the circumferential direction of the rotating sleeve.

[0016] Preferably, the elastic positioning bead includes a housing, a spring, and a ball. The positioning shaft has an insertion hole along its radial direction, and the housing is coaxially disposed in the insertion hole. The spring is disposed in the housing, and one end of the spring abuts against the ball.

[0019] The movable handrail of this application has at least the following beneficial effects:

[0020] This application's handrail is installed on the external structure via an installation component. When needed, the user grips the handrail body to overcome the elastic force of the elastic positioning component, causing the elastic positioning component to disengage from one positioning slot, allowing the handrail body to rotate freely to the desired position. Once the handrail body is rotated into position, the elastic positioning component re-inserts into another positioning slot, restricting the handrail body from rotating freely. This provides the handrail body with stable protection and support for the user. The handrail body of this application has a rotating unfolded and rotating retracted state. When not in use, the handrail body can be rotated to the retracted state, which helps to increase the interior space. The elastic positioning component fixes the handrail body in the unfolded or retracted state, preventing the handrail body from moving around and causing abnormal noise during vehicle operation.

[0036] This embodiment discloses a movable handrail for vehicles. The movable handrail in this embodiment can be installed on vehicles such as buses and rail trains to provide protection and support for disabled people or people with mobility impairments.

[0037] like Figure 1 As shown, the movable handrail includes a mounting component 100, a positioning shaft 200, an elastic positioning component 300, a rotating sleeve 400, and a handrail body 500, as detailed below:

[0038] like Figure 1 As shown, the mounting component 100 is mounted on the external structure 600, which can be a circular vertical support rod on a bus.

[0039] like Figure 2As shown, in some preferred embodiments, the mounting assembly 100 includes a first mounting portion 110 and a second mounting portion 120; the first mounting portion 110 is provided with a first receiving groove 100a; the second mounting portion 120 is provided with a second receiving groove 100b, the first receiving groove 100a and the second receiving groove 100b are connected to form a clamping hole 100c for wrapping around the outer structure 600, specifically: the clamping hole 100c surrounds the outer circumference of the outer structure 600, and can adapt to the mounting assembly 100 being mounted on outer structures 600 of different shapes, the first mounting portion 110 and the second mounting portion 120 are detachably connected, which facilitates the quick installation of the mounting assembly 100.

[0040] like Figure 2 As shown, in some preferred embodiments, the cross-sectional shape (horizontal section) of the first receiving groove 100a and the second receiving groove 100b is semi-circular. The two semi-circular receiving grooves can be connected to form a complete circular clamping hole 100c, which can be clamped to the vertical support rod of the bus.

[0041] like Figure 2 As shown, in some preferred embodiments, the first mounting portion 110 and the second mounting portion 120 are detachably connected. For example, the first mounting portion 110 and the second mounting portion 120 are detachably connected by a first screw 130, and there are multiple first screws 130. In this embodiment, the first mounting portion 110 and the second mounting portion 120 are connected and clamped to the external structure 600 by the first screws 130. This not only ensures that the first mounting portion 110 and the second mounting portion 120 are securely attached to the external structure 600, but also allows for quick installation through the screw connection. Alternatively, the detachable connection between the first mounting portion 110 and the second mounting portion 120 can also be achieved through existing methods such as snap-fit ​​connections.

[0042] like Figure 3 As shown, the outer periphery of the positioning shaft 200 is cylindrical. The positioning shaft 200 is mounted on the mounting assembly 100, specifically on the first mounting portion 110, with its axial direction aligned with the height. The axial end face of the positioning shaft 200 is fixedly connected to the first mounting portion 110 of the mounting assembly 100 by a second screw 210. After connection, the positioning shaft 200 cannot move or rotate relative to the first mounting portion 110. In this embodiment, the positioning shaft 200 is connected to the first mounting portion 110 using a second screw 210, a simple and quick connection method.

[0043] like Figure 4 As shown, Figure 4The positioning shaft 200 is not shown. In this embodiment, the elastic positioning component 300 is disposed on the positioning shaft 200, and the elastic positioning component 300 can extend and retract radially along the positioning shaft 200. When the elastic positioning component 300 is extended and retracted into the positioning groove 400a of the rotating sleeve 400, the relative position between the positioning shaft 200 and the rotating sleeve 400 is restricted, and the rotating sleeve 400 cannot rotate relative to the positioning shaft 200. If the rotating sleeve 400 needs to rotate, it is only necessary to overcome the elastic force of the elastic positioning component 300 to push the rotating sleeve 400 and the handrail body 500 to rotate, so that the elastic positioning component 300 can retract from the positioning groove 400a under the action of the inner peripheral wall of the rotating sleeve 400.

[0044] like Figure 5 As shown, in this embodiment, the rotating sleeve 400 is coaxially sleeved on the outer periphery of the positioning shaft 200. Multiple positioning grooves 400a are provided on the inner periphery of the rotating sleeve 400. These multiple positioning grooves 400a are spaced apart along the circumferential direction of the rotating sleeve 400. The elastic positioning component 300 can extend into the positioning grooves 400a to achieve positioning between the positioning shaft 200 and the rotating sleeve 400. Specifically, this embodiment illustrates three positioning grooves 400a. These three positioning grooves 400a are spaced apart along the circumferential direction of the rotating sleeve 400 on the inner periphery of the rotating sleeve 400. The spaced arrangement of multiple positioning grooves 400a allows the rotating sleeve 400 to be adjusted to its position and then re-engaged with the elastic positioning component 300 for positioning.

[0045] like Figure 4 As shown, in a preferred embodiment, there are multiple elastic positioning components 300 (two are shown in this embodiment) and multiple positioning grooves 400a (three are shown in this embodiment). The multiple elastic positioning components 300 are arranged at 90-degree intervals in the circumferential direction of the positioning shaft 200, and the multiple positioning grooves 400a are arranged at 90-degree intervals in the circumferential direction of the rotating sleeve 400. That is, the interval angle of the positioning grooves 400a is equal to the interval angle of the elastic positioning components 300. When the handrail body 500 rotates to the position, at least two elastic positioning components 300 can be inserted into the positioning grooves 400a to further ensure the stability of the handrail body 500 after it has rotated to the position.

[0046] like Figure 5As shown, in some preferred embodiments, the elastic positioning component 300 includes a plurality of elastic positioning beads 310, which are spaced apart on the positioning shaft 200. The length direction of the positioning groove 400a is configured to be the axial direction of the rotating sleeve 400, enabling all the elastic positioning beads 310 of the elastic positioning component 300 to be inserted into the same positioning groove 400a. Specifically, the positioning groove 400a is opened along the axial direction of the rotating sleeve 400, forming a through groove with a U-shaped cross-section. All the elastic positioning beads 310 of the elastic positioning component 300 can be inserted into the same positioning groove 400a. This ensures the stability of the handrail body 500 when it is in the unfolded state, and the multiple elastic positioning beads 310 can achieve multi-point force bearing, resulting in good overall force bearing performance.

[0047] like Figure 5 As shown, in a preferred embodiment, the elastic positioning bead 310 includes a housing 311, a spring (not shown), and a bead 312. The positioning shaft 200 is provided with an insertion hole 200a along its radial direction, and the housing 311 is coaxially disposed in the insertion hole 200a. The spring is disposed in the housing 311, and one end of the spring abuts against the bead 312. The bead 312 is disposed at the opening position of the housing 311, and the bead 312 can be inserted into the positioning groove 400a to realize the positioning between the positioning shaft 200 and the rotating sleeve 400. Specifically: the depth direction of the insertion hole 200a is configured to be radial to the positioning shaft 200. The insertion hole 200a can be a blind hole or a through hole. Circular housings 311 are coaxially inserted into the insertion holes 200a, and the housings 311 are connected to the inner peripheral wall of the insertion hole 200a (e.g., by adhesive bonding). One end of the spring abuts against the inner circumference of the housing 311, and the other end abuts against the ball 312. The extension and contraction direction of the spring is radial to the positioning shaft 200 (i.e., the length direction of the housing 311). The ball 312 is located in the opening of the housing 311 away from the positioning shaft 200. At least a portion of the ball 312 can be inserted into the positioning groove 400a, thereby restricting the rotation between the rotating sleeve 400 and the positioning shaft 200. In this embodiment, the elastic positioning ball 310 is installed using the insertion hole 200a method, which is simple and quick. When the rotating sleeve 400 and the armrest body 500 need to rotate, it is only necessary to overcome the elastic force of the spring so that the ball 312 retracts into the housing 311 and exits from the positioning groove 400a.

[0048] like Figure 5As shown, in a preferred embodiment, a limiting pin 140 is provided on the mounting assembly 100, and a limiting groove 400b is provided on the rotating sleeve 400. The length direction of the limiting groove 400b is configured to be circumferential to the rotating sleeve 400. The limiting pin 140 is inserted into the limiting groove 400b. Specifically, the limiting pin 140 is provided on the first mounting part 110 and extends upward. The lower end face of the rotating sleeve 400 is provided with a limiting groove 400b. The length direction of the limiting groove 400b is configured to be arc-shaped. At least a portion of the limiting pin 140 is inserted upward into the limiting groove 400b. Through the cooperation of the limiting pin 140 and the limiting groove 400b, the maximum rotation angle of the rotating sleeve 400 is limited, so as to prevent the positioning function of the elastic positioning bead 310 from failing and causing the handrail body 500 to lose its support function in the event of a major external force rigidly impacting the handrail body 500.

[0049] like Figure 2 As shown, in a preferred embodiment, a connecting sleeve 410 is provided on the outer periphery of the rotating sleeve 400. The connecting sleeve 410 is sleeved on one end of the handrail body 500, and the connecting sleeve 410 and the handrail body 500 are connected by a third screw 420. Specifically, the axial direction of the connecting sleeve 410 is configured to be radial to the rotating sleeve 400, and the connecting sleeve 410 and the rotating sleeve 400 can be integrally formed or welded. The connection between the connecting sleeve 410 and the handrail body 500 using a third screw 420 is simple and quick.

[0050] In some preferred embodiments, the rotating sleeve 400 may be directly welded to the handrail body 500 without the design of the connecting sleeve 410.

[0051] like Figure 1 As shown, at least a portion of the handrail body 500 in this embodiment is configured in a U-shape, and the handrail body 500 is used to provide protection and support for the user.

[0052] One working principle of the movable handrail in this embodiment is as follows:

[0053] When the movable handrail is not in use, push the handrail body 500 to the horizontal side of the vehicle body, so that the rotating sleeve 400 and the elastic positioning bead 310 rotate relative to each other. The elastic positioning bead 310 disengages from the positioning groove 400a of the rotating sleeve 400. Continue to push the handrail body 500, so that the handrail body 500 is pushed to a position that does not obstruct the movement of passengers. At this time, the handrail body 500 is pushed into place, and the elastic positioning bead 310 is inserted back into the positioning groove 400a to achieve the positioning of the handrail body 500.

[0054] When the movable handrail is needed, push the handrail body 500 to the other side of the vehicle body horizontally, so that the rotating sleeve 400 and the elastic positioning bead 310 rotate relative to each other. The elastic positioning bead 310 disengages from the positioning groove 400a of the rotating sleeve 400. Continue to push the handrail body 500 so that the handrail body 500 is pushed to the use position. At this time, the handrail body 500 is pushed into place, and the elastic positioning bead 310 is inserted back into the positioning groove 400a to realize the positioning of the handrail body 500.

[0055] The above description is merely a specific implementation of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
