[0002] Vehicle handrails are an important safety component for passenger safety and an indispensable part of many vehicles. Their design is directly related to the stability and safety of passengers when the vehicle is moving, turning, or braking.

[0003] The inventors discovered that current vehicle handrails have a fixed height, which cannot meet the needs of passengers of different heights, making them inconvenient for some passengers to grip, and the handrails have poor compatibility and limited applicability. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle handrail and a vehicle that can improve the compatibility and applicability of the handrail.

[0005] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides a vehicle handrail, comprising: The armrest base has a mounting slot; The handrail has its lower end slidably inserted into the mounting groove in the vertical direction, and the outer wall of the handrail is provided with a plurality of receiving grooves spaced apart. A limiting ball is disposed on the inner wall of the armrest base; A self-locking component is disposed on the armrest base. The self-locking component is used to limit the positioning ball, so that the positioning ball extends into the mounting groove and cooperates with the receiving groove to fix the armrest to the armrest base; the self-locking component is also used to release the limiting of the positioning ball.

[0006] In an optional embodiment, multiple limiting balls are provided on the armrest base, and the multiple limiting balls are located on the same horizontal plane.

[0007] In an optional embodiment, the self-locking component includes a retaining ring, and an annular sleeve is provided in the mounting groove. The annular sleeve and the inner wall of the armrest base together form an annular groove for inserting the retaining ring. The retaining ring has a through hole for accommodating the limiting ball, and the inner wall of the annular sleeve has an unlocking groove for accommodating the limiting ball.

[0008] In an optional embodiment, the thickness of the annular sleeve is less than the diameter of the limiting ball.

[0009] In an optional embodiment, the self-locking member further includes an elastic element disposed within the annular groove, the elastic element being used to provide a restoring force to the retaining ring to move away from the limiting ball.

[0010] In an optional embodiment, when the elastic element is in a free state, the unlocking groove is located above the limiting ball.

[0011] In an optional embodiment, when the elastic element is in a free state, the unlocking groove is located below the limiting ball.

[0012] In an optional embodiment, the elastic element includes a spring, one end of which is connected to the armrest base and the other end of which is connected to the retaining ring.

[0026] Vehicle handrails, though seemingly simple, are crucial safety components and are an important safety guarantee for passengers riding public transportation. Their design directly affects passenger stability and safety during vehicle movement, turning, and braking. However, traditional vehicle handrails have the following problems: The fixed height of vehicle handrails cannot accurately accommodate the needs of passengers of different heights, resulting in some people not being able to hold on firmly or stand steadily when riding. At the same time, the current vehicle handrails are inconvenient to install and remove, affecting the efficiency of installation and removal and increasing production costs.

[0027] To address the aforementioned technical problems, this utility model provides a vehicle handrail and a vehicle. The overall structure, working principle, and technical effects of the vehicle handrail and vehicle provided by this utility model are described in detail below through embodiments and with reference to the accompanying drawings.

[0028] On the one hand, please refer to Figures 1-5 This invention provides a vehicle handrail to offer passengers a reliable grip point, helping them maintain stability and reducing the risk of falls, slips, and collisions during vehicle operation. The handrail provided by this invention can be applied to buses, coaches, electric buses, shuttle buses, and other vehicles.

[0029] Please refer to Figures 1-3 The vehicle handrail provided by this utility model includes a handrail base 100, a handrail rod 200, a limiting ball 300, and a self-locking component 400. The handrail base 100 is disposed on the vehicle floor and has a mounting groove 110 with an upper opening. The lower end of the handrail rod 200 slides vertically through the mounting groove 110 of the handrail base 100. Furthermore, multiple annular receiving grooves 210 are evenly spaced on the lower outer wall of the handrail rod 200. The limiting ball 300 is disposed on the inner wall of the handrail base 100. A self-locking component 400 is disposed on the armrest base 100. The self-locking component 400 is used to limit the limiting ball 300, so that the limiting ball 300 extends partially into the armrest base 100. Thus, when the armrest bar 200 is located within the armrest base 100, the limiting ball 300 extends partially into the receiving groove 210, thereby limiting and fixing the armrest bar 200 to the armrest base 100 through the limiting ball 300. The self-locking component 400 can also release the limiting ball 300, thereby releasing the fixing of the limiting ball 300 to the armrest bar 200, allowing the armrest bar 200 to move freely along the length direction of the mounting groove 110.

[0030] By setting multiple receiving grooves 210 on the surface of the handrail 200 and setting a limiting ball 300 in the handrail base 100, the handrail 200 is fixed to the handrail base 100 by a self-locking component 400 limiting the limiting ball 300. When the height of the handrail 200 needs to be adjusted, the self-locking component 400 releases the limiting ball 300, driving the handrail 200 to move along the length direction of the mounting groove 110. After the height of the handrail 200 is adjusted to the correct position, the limiting component again limits the limiting ball 300, so that part of the limiting ball 300 is located in the corresponding receiving groove 210, thus achieving the limiting and fixing of the handrail 200. This facilitates the height adjustment of the handrail 200, improves the compatibility and applicability of the handrail, and thus improves passenger comfort. At the same time, compared with the traditional handrail 200 installation method using bolt drilling, it has the advantages of high installation efficiency and saving time and effort.

[0031] Please refer to Figure 3 To enhance the fixing and limiting effect of the limiting ball 300 on the handrail 200, in some optional embodiments, multiple limiting balls 300 are provided on the handrail base 100. To simultaneously limit or release the limiting of multiple limiting balls 300, the multiple limiting balls 300 are located in the same horizontal plane. Specifically, in this embodiment, the limiting ball 300 is a steel ball; in other embodiments, the limiting ball 300 can also be other hard spheres that meet the design requirements.

[0032] Please refer to Figures 3-5 In some optional embodiments, the self-locking member 400 includes a retaining ring 410, and an annular sleeve 120 is provided on the armrest base 100 and located within the mounting groove 110, with the axis of the annular sleeve 120 coinciding with the axis of the mounting groove 110. The annular sleeve 120 and the inner wall of the armrest base 100 together form an annular groove 130 for inserting the retaining ring 410. Further, a through hole 121 for accommodating a limiting ball 300 is provided on the retaining ring 410, and an unlocking groove 411 for accommodating the limiting ball 300 is provided on the inner wall of the annular sleeve 120. Furthermore, the thickness of the annular sleeve 120 is less than the diameter of the limiting ball 300, so that the limiting ball 300 can extend beyond the annular sleeve 120 and engage with the receiving groove 210 to fix the armrest 200.

[0033] The principle of height adjustment of the handrail 200 provided in this embodiment is as follows: when the retaining ring 410 moves in the annular groove 130 and moves to the point where the inner wall of the retaining ring 410 abuts against the limiting ball 300, one side of the limiting ball 300 abuts against the retaining ring 410, and the other side of the limiting ball 300 extends into the mounting groove 110 and cooperates with the receiving groove 210 on the surface of the handrail 200, thereby limiting and fixing the handrail 200 through the limiting ball 300. When the height of the handrail 200 needs to be adjusted, the retaining ring 410 is moved along the annular groove 130 until the unlocking groove 411 and the limiting ball 300 are on the same horizontal plane. At this time, the inner wall of the retaining ring 410 is no longer held by the limiting ball 300. When the handrail 200 is driven to move, the handrail 200 will push the limiting ball 300 and move one side of the limiting ball 300 into the unlocking groove 411. The other side of the limiting ball 300 no longer extends into the mounting groove 110. The limiting ball 300 releases the limiting fixation on the handrail 200, so the handrail 200 can move freely along the length direction of the mounting groove 110. Once the handrail 200 is adjusted to the correct height, the retaining ring 410 is moved again, causing the unlocking groove 411 and the limiting ball 300 to be misaligned in the horizontal direction. The retaining ring 410 pushes the limiting ball 300 partially into the mounting groove 110. At this time, the limiting ball 300 again abuts against the inner wall of the retaining ring 410 on one side and extends into the mounting groove 110 on the other side, cooperating with the corresponding receiving groove 210, thereby limiting and fixing the handrail 200 again.

[0034] Please refer to Figure 4 and Figure 5 To facilitate self-locking after adjusting the height of the handrail 200, in some optional embodiments, the self-locking component 400 further includes an elastic element 500. The elastic element 500 is disposed in the annular groove 130. In the free state, the inner wall of the retaining ring 410 abuts against the limiting ball 300, causing one side of the limiting ball 300 to extend into the mounting groove 110 and cooperate with the receiving groove 210. When the retaining ring 410 is driven to move to the unlocking groove 411 and the limiting ball 300 are on the same horizontal plane, the elastic element 500 is in an energy storage state, and the elastic element 500 provides a rebound force to the retaining ring 410 to move away from the limiting ball 300.

[0035] Specifically, in some optional embodiments, when the elastic element 500 is in its free state, the unlocking groove 411 is located above the limiting ball 300. When the handrail 200 needs to be unlocked, the retaining ring 410 needs to be pressed down to move the unlocking groove 411 to the same horizontal plane as the limiting ball 300. During this process, the elastic element 500 stores energy. After the height of the handrail 200 is adjusted to the correct position, the retaining ring 410 is released. Under the action of the elastic element 500, the retaining ring 410 moves upward until the unlocking groove 411 is misaligned with the limiting ball 300, driving one side of the limiting ball 300 to move into the mounting groove 110 and fit into the corresponding receiving groove 210, thus fixing the handrail 200 again.

[0036] In some alternative embodiments, when the elastic element 500 is in its free state, the unlocking groove 411 can also be located below the limiting ball 300. In this case, to unlock the handrail 200, the retaining ring 410 needs to be pulled upwards to move the unlocking groove 411 to the same horizontal plane as the limiting ball 300. During this process, the elastic element 500 stores energy. After the height of the handrail 200 is adjusted to the correct position, the retaining ring 410 is released. Under the action of the elastic element 500, the retaining ring 410 moves downwards until the unlocking groove 411 is misaligned with the limiting ball 300, driving one side of the limiting ball 300 to move into the mounting groove 110 and fit into the corresponding receiving groove 210, thus fixing the handrail 200 again.

[0037] Please refer to Figure 5 In this embodiment, the elastic element 500 includes a spring, one end of which is connected to the armrest base 100, and the other end of which is connected to the retaining ring 410. In some alternative embodiments, the elastic element 500 may also be made of elastic materials such as rubber or shape memory alloy.

[0038] Please refer to Figure 5 To facilitate the positioning of the handrail 200 when it is inserted into the handrail base 100, in this embodiment, the vehicle handrail also includes a positioning pin 600. The positioning pin 600 is installed on the handrail base 100 and located in the mounting groove 110, and the axis of the positioning pin 600 coincides with the axis of the mounting groove 110. The handrail 200 is a hollow rod body. When the handrail 200 is inserted into the handrail base 100, the positioning pin 600 is adapted to the inner wall of the handrail 200.

[0039] On the other hand, this utility model also provides a vehicle with the above-mentioned vehicle handrail, with the handrail base 100 installed on the bus floor. By setting the above-mentioned vehicle handrail, passengers can easily adjust the height of the handrail, improve the riding comfort of passengers, and thus improve the applicability of the bus.

[0040] In summary, the implementation principle of the vehicle handrail and vehicle provided by this utility model is as follows: Multiple receiving grooves 210 are provided on the surface of the handrail 200, and a limiting ball 300 is provided within the handrail base 100. A self-locking component 400 limits the limiting ball 300, thereby fixing the handrail 200 to the handrail base 100. When the height of the handrail 200 needs to be adjusted, the self-locking component 400 releases the limiting ball 300, driving the handrail 200 to move along the length of the mounting groove 110. After the height of the handrail 200 is adjusted to the correct position, the limiting component again limits the limiting ball 300, ensuring that part of the limiting ball 300 is located within the corresponding receiving groove 210, thus achieving the limiting and fixing of the handrail 200. This facilitates the adjustment of the handrail 200's height, improving the handrail's compatibility and applicability.

[0041] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
