Description

Technical Field

[0001] This utility model relates to the technical field of bus seat installation equipment, specifically to a support structure for passenger seats on buses. Background Technology

[0002] With the rapid development of urban public transportation, the installation structure and maintenance convenience of bus seats are receiving increasing attention. Traditional bus seat support structures often use fixed brackets directly welded to the bus floor or installed using multiple dispersed support feet. These structures present the following problems in practical use: 1. High installation positioning accuracy is required, necessitating individual adjustment of multiple support points, leading to low assembly efficiency; 2. Insufficient overall structural rigidity, making them prone to structural deformation under frequent vehicle starts and stops and bumpy conditions, posing safety hazards; 3. Maintenance requires complete disassembly of the seat assembly, especially for the equipment under the seat, which necessitates complete removal of the seat, increasing maintenance costs and time; 4. Traditional frame structures occupy a large amount of space, affecting the space available for pipelines under the bus floor. Therefore, a new type of seat support structure that combines ease of installation, structural stability, and maintenance convenience is urgently needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a support structure for passenger seats on buses, so as to solve the problem that the traditional installation support structure for bus seats cannot meet the current needs.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A support structure for a passenger seat on a bus includes a seat body; a transverse support rod is provided at the bottom of the seat body; the transverse support rod is arranged along the width direction of the seat body; a longitudinal stretcher is provided at the bottom of the transverse support rod; the longitudinal stretcher includes a U-shaped plate; a first extension plate and a second extension plate are respectively provided at the two protruding ends of the U-shaped plate; both the first extension plate and the second extension plate extend outward from the U-shaped plate; a positioning hole is opened in the middle of the U-shaped plate; the transverse support rod and the U-shaped plate are connected to the positioning hole by a bolt assembly; positioning holes are opened on both the first extension plate and the second extension plate; the bus body and the longitudinal stretcher are connected at the positioning hole by a bolt assembly.

[0006] Preferably, the seat body includes two adjacent seats placed side by side, and the length of the lateral support rod is consistent with the overall width of the seat body.

[0007] Furthermore, there are two transverse support rods, which are placed parallel to each other; the two transverse support rods are respectively located at the front and rear positions of the middle of the seat body.

[0008] Preferably, the transverse support is a C-shaped channel steel, with its slot side attached to the top surface of the longitudinal stretcher; the bolt assembly extends downward from the slot of the transverse support and passes through the positioning holes on the U-shaped plate.

[0009] Furthermore, there are two longitudinal stretchers; the two longitudinal stretchers are respectively set on the transverse support rod near its end, so that the two U-shaped plates and the transverse support rod form a grid-like structure.

[0010] Preferably, the first extension plate, the second extension plate, and the U-shaped plate are integrally formed from the same material; and the corners at the joints of the three are rounded.

[0011] Preferably, the length of the first extension plate is greater than the length of the second extension plate; and a reinforcing rib is also provided between the first extension plate and the U-shaped plate.

[0012] Furthermore, the first extension plate is positioned directly opposite the backrest of the seat body.

[0013] The beneficial effects of this utility model are reflected in the following aspects:

[0014] 1. Its structure is simple and easy to install. Through the combination design of standardized positioning holes and C-shaped channel steel, the multi-point distributed support is optimized into the overall frame positioning. During installation, only the main connection nodes need to be aligned, which reduces the positioning accuracy requirements and improves assembly efficiency.

[0015] 2. A grid-shaped support frame was designed for the dual-seat structure to improve structural rigidity. Reinforced ribs and rounded corners were also used to effectively suppress vehicle deformation when driving on bumpy roads.

[0016] 3. The longitudinal stretcher and transverse support rods are detachably connected, allowing the longitudinal stretcher to be removed separately during maintenance while keeping the main seat. This saves more time compared to the traditional whole disassembly method and is especially convenient for the inspection and maintenance of electrical wiring at the bottom of the seat.

[0017] 4. By using the asymmetrical design of the first and second extension plates, combined with the triangular support structure of the reinforcing ribs, stress concentration in the bending part is reduced, and structural reliability is improved. Attached Figure Description
