Description

Technical Field

[0001] The utility model relates to the technical field of bus handrails, in particular to a spring upright seat for bus handrails. Background Art

[0002] With more and more pure electric buses now placing their batteries on the roof, the weight on the roof has increased significantly. When the vehicle travels over bumpy roads, the heavy roof often deforms significantly, placing significant stress on the handrail posts connecting the vehicle to the roof. Over time, this can lead to several problems with the post handrails: first, the through-bolts connecting the post top base to the handrail can shear and break; second, the through-bolts can rub against the post tube wall, enlarging the post hole and causing the bolts to loosen and make unusual noises; third, the through-bolts connecting the post base to the handrail can also cause the same problem; and fourth, the post handrail can crack the pre-embedded welds at the top base, reducing the durability of the bus handrails.

[0003] Therefore, it is necessary to develop a spring seat for bus handrails. This spring seat can effectively solve this type of problem. It does not bring more complexity to the handrail design, but also solves the strong stress caused by the deformation of the vehicle body to the handrail column while ensuring strength. Utility Model Content

[0004] The purpose of the utility model is to provide a spring upright seat for a bus handrail to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a spring upright seat for a bus handrail, comprising a upright seat body, a telescopic slot being provided at the inner center of the upright seat body, a handrail upright post being mounted at the top end of the upright seat body, and a limit post being provided at the inner bottom center of the telescopic slot;

[0006] A limiting block is arranged inside the handrail column.

[0007] Preferably, an annular groove is provided on the upper part of the telescopic groove, and a rubber bushing is installed inside the annular groove.

[0008] Preferably, the bottom end of the handrail column is located inside the telescopic slot, and the outer wall of the handrail column is slidably connected to the inner wall of the telescopic slot.

[0009] Preferably, a spring A is provided below the outer wall of the limiting column, and a rubber pad is provided above the outer wall of the limiting column.

[0010] Preferably, a spring B is provided at the bottom of the limit block, and a limit ring is provided at the bottom end of the spring B.

[0011] Preferably, a buffer plate is provided at the bottom of the limiting ring, and the buffer plate is located below the inner part of the handrail column.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] By arranging the limit column in the telescopic groove on the upright seat body, and slidingly fitting the spring A and the rubber pad on the outer wall of the limit column, the handrail column is installed in the telescopic groove, so that the rubber pad is subjected to the rigidity and reaction force of the spring A, and thus the handrail column can be supported and buffered, thereby protecting the handrail column from the stress caused by the bus roof, and minimizing the stress between the handrail column and the upright seat body caused by the bus roof, thereby minimizing the occurrence of bolt breakage or abnormal noise, and minimizing the occurrence of cracks in the welded parts.

[0014] By providing a limiting ring at the bottom of the limiting block inside the handrail column, and providing a spring B between the limiting ring and the limiting block, and matching it with a buffer plate on the bottom end of the limiting ring, when the handrail column undergoes a large downward deformation, the limiting column presses against the buffer plate, and in conjunction with spring B and spring A, the handrail column and the upright seat body are protected from the impact of top cracking to a great extent, while not increasing the complexity of the handrail column design, and solving the problems of bolt breakage and loosening of the handrail column in the vehicle due to excessive stress, and indirectly allowing a larger vehicle body error when installing the handrail, thereby effectively improving the durability and installation efficiency of the bus handrail.

A limiting column 3 is provided at the inner bottom center position of the telescopic groove 101. A spring A301 is provided below the outer wall of the limiting column 3, and a rubber pad 302 is provided above the outer wall of the limiting column 3. The limiting column 3 is set in the telescopic groove 101 on the upright seat body 1, and the spring A301 and the rubber pad 302 are slidably mounted on the outer wall of the limiting column 3. The handrail column 2 is installed in the telescopic groove 101, so that the rubber pad 302 is subjected to the rigidity and reaction force of the spring A301, which can support and buffer the handrail column 2, thereby ensuring that the handrail column 2 is not subjected to the stress brought by the bus roof, and avoiding as much as possible the stress between the handrail column 2 and the upright seat body 1 caused by the bus roof, resulting in the occurrence of bolt breakage or abnormal noise, and also avoiding as much as possible the occurrence of top cracking of the welding part;

[0022] A limit block 4 is provided inside the handrail column 2, and a spring B401 is provided at the bottom of the limit block 4.

When the handrail column 2 produces a large sinking deformation, the limit column 3 presses the buffer plate 403, and cooperates with the spring B401 and the spring A301 to protect the handrail column 2 and the upright seat body 1 from being affected by the top crack to a great extent.

[0023] Working principle: When using the utility model, the upright seat body 1 is installed at the designated position of the bus, and the handrail column 2 is slidably docked in the telescopic groove 101 on the upright seat body 1, so that the handrail column 2 can be adjusted upward during the installation and fixing process, ensuring that a larger vehicle body error is allowed when the handrail column 2 is installed. By setting the limit column 3 in the telescopic groove 101 on the upright seat body 1, and slidingly fitting the spring A301 and the rubber pad 302 on the outer wall of the limit column 3, according to the handrail column 2 being installed in the telescopic groove 101, the rubber pad 302 is subjected to the rigidity and reaction force of the spring A301, and the handrail column 2 can be supported and buffered, ensuring that the handrail column 2 is not subjected to the stress brought by the bus roof, and trying to avoid the bolt breakage or In order to prevent abnormal noise from occurring and to avoid the occurrence of top cracking of the welding part, a limit ring 402 is set at the bottom of the limit block 4 on the inside of the handrail column 2, and a spring B401 is set between the limit ring 402 and the limit block 4, and a buffer plate 403 is installed on the bottom end of the limit ring 402.
