Description

A handrail structure, a handrail tube assembly, and a vehicle

[0001] This application claims priority to Chinese Patent Application No. 202410875115.9, filed on June 29, 2024, entitled "A Handrail Structure, Handrail Tube Assembly and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0003] Handrails inside buses are crucial support structures for passengers standing while riding. In the overall design of buses, the vehicle frame serves as the load-bearing structure, supporting the weight of the battery pack and the vehicle itself. As a gripping structure for passengers, existing installation methods almost always involve fixing the handrail tubes to the vehicle body, meaning they are fixed to profiles at both the top and bottom. This doesn't consider absorbing the impact of vehicle deformation, especially the deformation caused by the downward pressure of the battery pack. However, in practice, handrail tubes frequently break due to their inability to absorb deformation, leading to structural failure and the inability to provide support for passengers, ultimately causing the entire vehicle to stop operating.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the protection scope of the present application.

[0052] Some embodiments disclose a bus handrail, comprising a handrail rod, a telescopic handrail assembly and a limiting assembly, the telescopic handrail assembly comprises two mounting segments and a plurality of flexible handrail segments, the flexible handrail segments are connected between the two mounting segments, the two mounting segments are arranged on the handrail rod and the distance of the two mounting segments along the extension direction of the handrail segments is adjustable, the limiting assembly is arranged on the mounting segment, and the distance between the two mounting segments is adjusted according to the requirement, and the limiting assembly fixes the mounting segment on the handrail rod; the plurality of flexible handrail segments are arranged at intervals along the circumference of the handrail rod; the flexible handrail segments can be in a tension state, a compression state or a natural state according to the distance between the two mounting segments.

[0053] However, the above technical solution has the following defects: the structure can only realize the pre-adjustment of the axial length of the handrail pipe, and essentially belongs to a fixed handrail structure mode that cannot be adjusted, so it cannot meet the absorption of the displacement of the handrail pipe from the deformation of the bus body under the running conditions of the actual vehicle; the flexible segment of the structure is part of the body of the handrail pipe, and no matter in its normal state or in the elongated or shortened state, the structure design occupies extra space in the vehicle cabin. The structure is relatively complex, involves many parts and is not a modular assembly design, which will lead to a decrease in the assembly efficiency of the actual vehicle and is not conducive to the later maintenance.

[0054] In order to solve the above technical problems, the embodiments of the present application make the following improvements.

[0055] Please refer to FIG. 1 and FIG. 2, FIG. 1 is an exploded structural schematic diagram of a handrail structure provided in an exemplary embodiment of the present disclosure.

Through the above technical solution, when the armrest tube 50 is impacted along the first direction X and / or the second direction Y and / or the third direction Z, the first buffer 21 can move along the first direction X, and the second buffer 22 can rotate along the second direction Y and / or the third direction Z, so as to absorb the impact force along the direction of deformation to buffer the armrest tube 50, avoiding the armrest tube 50 being directly impacted, so as to avoid the situation that the armrest tube 50 is deformed or even broken due to excessive force, which is beneficial to prolong the service life of the armrest tube 50.

In this way, the position of the first buffer 21 in the accommodating cavity 11 can be ensured, so as to avoid the offset of the first buffer 21 and ensure the stability of the first buffer 21 during use.

[0065] The connection between the first buffer 21 and the receiving surface 2211 can be welding or bonding, which can meet the fixing requirement therebetween, and the specific setting condition should be selected according to the use environment of the device, so as to improve the applicability and application range of the device.

In this way, the running of the elastic member by the handrail top seat 40 can be avoided, so that the buffering effect of the elastic member can be ensured.

[0086] In other embodiments of the present application, the top of the V-shaped support can be improved in structure to become a fixed support of the spring, and the free end of the spring can directly contact the handrail top seat 40 to transmit displacement, and the effect and advantages of the present application can still be achieved.

[0087] A handrail structure is arranged between the handrail top seat 40 and the handrail tube 50, and the handrail structure comprises: a buffer assembly 20 comprising a first buffer 21 and a second buffer 22; wherein the first buffer 21 is connected between the handrail top seat 40 and the second buffer 22 to buffer the handrail tube 50 in a first direction, and the second buffer 22 is connected between the first buffer 21 and the handrail tube 50 to buffer the handrail tube 50 in a second direction and / or a third direction, the first direction, the second direction and the third direction are intersected with each other, and the first direction, the second direction and the third direction are arranged in different planes, and the first direction is the axial direction of the handrail tube 50.

[0088] In some embodiments, the handrail structure further comprises a connecting cylinder 10 having a receiving cavity 11, and one end of the handrail top seat 40 is connected to the connecting cylinder 10; the first buffer 21 is an elastic member and is arranged in the receiving cavity 11, and the first buffer 21 is elastically connected between the handrail top seat 40 and the second buffer 22 in the first direction. In the present application, the elastic member is specifically a spring, which has a relatively simple structure and is very convenient to manufacture and process, thereby reducing the production cost and manufacturing difficulty. Due to the simple structure and convenient manufacturing, the processing cost of the spring can be reduced, and the spring has high internal resistance, strong impact resistance and strong reset ability, which enables the spring to withstand a large impact and has good reset ability to quickly return to the original state, thereby ensuring good buffering effect on the handrail tube 50.

[0089] In some embodiments, the second buffer is rotationally connected between the first buffer and the handrail tube 50 in the second direction and / or the third direction.

[0090] In the present application, the elastic member needs to have a certain reserved compression amount in the initial state after installation, which can generate a force on the handrail tube 50 to avoid collision between structural members and abnormal noise.

[0091] As shown in FIG. 13, which is an exploded view of the impact displacement of the handrail tube 50, in the case of the vehicle where the handrail tube 50 is broken, the handrail tube 50 connected with the handrail top seat 40 accounts for the majority, and the breakage is mainly caused by the displacement impact F caused by the deformation of the roof downward, the actual working condition of the displacement impact in the front-rear direction of the vehicle is less, and the displacement impact in this direction is smaller. The F direction displacement of the roof downward directly causes the handrail top seat 40 to move downward by the same displacement, which is decomposed into the axial and radial directions of the handrail tube 50, respectively, and has a certain value. Since there is a constraint at the lower part, when the impact value is large, since there is a certain distance from the lower constraint part, the axial force and the tangential force received by the handrail tube 50 will be converted into bending and shearing load, so that the handrail tube 50 is prone to breakage risk. After the handrail structure is adopted, after the handrail top seat 40 is subjected to the same F direction displacement impact, the axial direction displacement is converted into the compression stroke of the spring, and the tangential displacement is converted into the Y / Z rotation displacement. The handrail tube 50 body is not directly impacted, and the breakage risk is greatly reduced, thereby prolonging the service life of the handrail tube 50.

[0092] As shown in FIG. 14, according to the second aspect of the present application, a handrail tube assembly is provided, which comprises the above-mentioned handrail structure and the handrail tube 50. The handrail has all the beneficial effects of the above-mentioned handrail structure, which will not be repeated here.

[0093] According to the third aspect of the present application, a vehicle is provided, which comprises the above-mentioned handrail tube assembly. The vehicle has all the beneficial effects of the above-mentioned handrail structure, which will not be repeated here.

[0094] In the handrail structure of the embodiments of the present application, the handrail structure comprises a connecting cylinder 10 and a buffer assembly 20. The connecting cylinder 10 has a receiving cavity 11, one end of the handrail top seat 40 is at least partially arranged in the receiving cavity 11 and is fixedly connected with the connecting cylinder 10. The buffer assembly 20 is arranged in the receiving cavity 11 and is spaced apart from the inner wall of the connecting cylinder 10. The buffer assembly 20 comprises a first buffer 21 and a second buffer 22. One end of the first buffer 21 is connected with one end of the second buffer 22. The other end of the second buffer 22 is hingedly connected with the handrail tube 50. The first buffer 21 is arranged to move in a first direction. The second buffer 22 is arranged to rotate in a second direction and / or a third direction. Through the above technical solution, when the handrail tube 50 is impacted in the first direction and / or the second direction and / or the third direction, the first buffer 21 can move in the first direction, and the second buffer 22 can rotate in the second direction and / or the third direction. In this way, the impact force can be absorbed along the deformation direction to buffer the handrail tube 50, so as to avoid the handrail tube 50 from being directly impacted, thereby avoiding the case that the handrail tube 50 is deformed or even broken due to excessive force, and prolonging the service life of the handrail tube 50.
