Description

Technical Field

[0001] This utility model relates to the technical field of bus interior device technology, specifically to a hidden handrail top mounting structure for buses. Background Technology

[0002] Currently, the installation method of handrail top mounts in buses usually adopts exposed fixing connectors. Although this design is simple and convenient, it also has some drawbacks: firstly, it affects the overall aesthetics of the vehicle interior; secondly, the exposed fixing components may cause injury to passengers in emergency situations. Therefore, it is necessary to design a solution that hides the fixing structure of the handrail top mount within the air duct profile to improve the integrity and safety of the bus interior. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a hidden handrail top mounting structure for buses, so as to solve the problem that the current exposed handrail top mountings on buses are not aesthetically pleasing and pose certain safety hazards to passengers during driving.

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

[0005] A concealed handrail mounting structure for a bus includes a handrail; the lower part of the handrail is mounted on the floor of the bus compartment; a support plate is installed on the inner top of the bus compartment; the inner wall of the bus compartment and the support plate form an air duct; positioning holes are opened on the support plate; a positioning clip is installed inside the air duct; a mounting bracket is detachably mounted on the positioning clip; the mounting bracket is a cantilever structure, and the lower end of the mounting bracket protrudes from the positioning hole on the support plate; the upper part of the handrail is correspondingly mounted on the protruding end of the mounting bracket.

[0006] Preferably, the support plate is installed at an angle at the corner of the top of the carriage; the positioning hole is set on the support plate near the top of the carriage.

[0007] Preferably, the positioning plate is a profile component; the positioning plate is installed on the upper top of the carriage; a slot is provided on the positioning plate; one end of the top seat is detachably installed at the slot position by a bolt assembly.

[0008] A through hole is provided on the top of the top seat; the bolt assembly includes a T-bolt; the bolt head of the T-bolt is engaged in a slot, and the threaded part passes through the slot and the through hole on the top seat, after which a washer, a gasket, and a nut are installed in sequence; the top seat is detachably pressed onto the positioning plate by the bolt assembly for installation.

[0009] Preferably, the top seat includes a horizontal plate, a connecting rod, and a connector connected to each other from top to bottom; the horizontal plate is mounted on a positioning plate; the lower end of the connecting rod extends from the positioning hole of the support plate; the connector is a tubular component, and the top of the handrail is inserted into the connector and connected by a pin or bolt.

[0010] Preferably, the upper end of the handrail is a folding rod structure that is inclined toward the positioning hole on the support plate.

[0011] Preferably, after the positioning plate and the support plate are installed, the cavity formed by the two is not connected to the air duct.

[0012] The beneficial effects of this utility model are reflected in the following aspects:

[0013] 1. Through optimized design, a stable installation of the armrest top bracket was achieved while maintaining a clean and aesthetically pleasing vehicle interior. The connection between the armrest top bracket and the positioning plate was concealed within the original air duct, resulting in a more minimalist and streamlined overall interior style.

[0014] 2. By reducing the exposed portion of the top connection of the handrail, the risk of passengers being scratched or bumped and injured by exposed fasteners in emergency braking, crowding, or other situations is reduced, creating a safer riding environment for passengers. In addition, the structure is reasonably designed and the connections between the components are firm. Even when the bus encounters complex conditions such as bumps or rapid acceleration during operation, the top of the handrail can still remain stable, further ensuring the safety of passengers holding on.

[0015] 3. The positioning plate and the top seat are both detachably connected to the top of the handrail, which facilitates the inspection and replacement of the handrail top seat by the staff; it reduces the difficulty of maintenance, shortens the maintenance time, and saves maintenance costs; at the same time, after the positioning plate and the support plate are installed, the cavity formed by the two is separated from the original air duct, which can effectively avoid the influence of airflow and dust in the air duct on the fixed structure, reduce the wear and corrosion of components caused by external environmental factors, and extend the service life of the handrail top seat fixed structure.
