Description

Technical Field

[0001] The utility model relates to the technical field of bus roof covers, in particular to a bus and a roof cover and a top side skin thereof. Background Art

[0002] The roof and side skin structure of traditional buses is generally made of galvanized sheet rolled. The material is relatively soft and cannot bring out the side window stop, and cannot be directly used as a fixing point for exterior trim and other functional accessories outside the vehicle; and the material will rebound after rolling, and the errors in the production of the frame and the skin will be superimposed, making it difficult for the skin to fit the frame, thus affecting the waterproof performance of the vehicle;

[0003] The traditional skin structure is connected to the frame through welding, and the entire vehicle frame is anti-corrosive through the electrophoretic process. However, it is inevitable that the electrophoretic primer is weak in local areas such as the welds and fitting surfaces of the bus. After a period of deformation such as bending and twisting of the vehicle body, corrosion will appear in some parts of the skin.

[0004] When installing the top side exterior decoration parts on the traditional top side skin, it is necessary to weld the reverse bolts and their connecting plates on the top cover frame. The bolt positioning accuracy is poor. The top side exterior decoration part fixing bracket is connected to the top cover frame by bolts. The bolts need to be sealed with glue, and the overall steps are relatively cumbersome.

[0005] In view of this, the applicant filed this application after studying the existing technology. Utility Model Content

[0034] Specifically, the fixed slide groove 12 runs through from front to back. The fixed slide groove 12 is used for the fixing bracket 4 of the top side exterior decoration 2, and its adjustment amount along the front and rear direction of the vehicle is not limited. Compared with the traditional structure, the reverse bolts and their connecting plates are reduced, which greatly facilitates the workshop operation. The reinforcing cavity 16 is set at the position adjacent to the fixed slide groove 12, which can effectively increase the strength of the top side skin at the slide groove and prevent the fixed slide groove 12 from deforming after long-term use. In addition, the slide groove and the reinforcing cavity 16 are set to a plane on the side facing the fixed bracket 4, which increases the contact surface between the fixed bracket 4 and the top side skin, making it more stable and firm to fix, and avoiding loosening after long-term use.
