[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Depend on Figures 1 to 3 As shown, this utility model embodiment provides a bus roof decorative cover structure, including a cover body 1. The cover body 1 is connected to the upper end of the bus roof frame 2. The cover body 1 is generally rectangular in shape with a height of less than 40cm. The width is determined according to the actual proportions of the bus. The cover body 1 is mainly made of fiberglass, and the rust prevention level of the frame is the same as that of the bus body. The cover body 1 is required to have uniform thickness and a smooth surface, and burrs and protrusions need to be removed. Preferably, the cover body 1 is internally divided into an intake adapter box 3 and an exhaust chamber 4. The bottom of the intake adapter box 3 is provided with a flange interface 6 for connecting the intake hose 5 of the bus intake system. One end of the intake hose 5 is connected to the intake adapter box 3 through the flange interface 6, and the other end is connected to the intake end of the engine (not shown in the figure). There are various connection methods, which will not be described in detail here. A hexagonal grille 7 connected to the outside is provided on one side of the intake adapter box 3 to serve as the main intake end of the intake adapter box 3. Meanwhile, the exhaust chamber 4 is used for the exhaust of the bus. An exhaust pipe outlet 8 is provided on one side of the cover 1 to serve as the outlet end of the engine exhaust pipe (not shown in the figure). It should be noted that a sealing strip is needed to enhance the seal between the exhaust pipe outlet 8 and the exhaust chamber 4. Thus, the cover 1 integrates the functions of vehicle air intake and exhaust. Top air intake provides cleaner air than bottom air intake, and top exhaust reduces the impact of exhaust heat on pedestrians, improving the experience for pedestrians getting on and off the bus or passing by.

[0021] Preferably, the bottom end of the cover 1 extends radially to form an adhesive stop 9 for fixing the cover 1 to the vehicle roof. The decorative cover 1 is fixed to the vehicle roof using an adhesive stop. The adhesive stop design eliminates the traditional self-tapping screw fixing method, fundamentally solving the risk of water leakage caused by loose fasteners or poor sealing. The material selection for the adhesive stop must meet weather resistance requirements and maintain stable bonding performance under different environmental conditions such as high temperature, low temperature, and humidity. During the bonding process, the contact surfaces of the vehicle roof and the adhesive stop 9 are first cleaned to remove oil and impurities, then a special adhesive is applied, and appropriate pressure is applied to ensure a firm bond. After bonding, a comprehensive inspection of the sealing performance is required to ensure there is no air or water leakage.

[0022] As a preferred implementation, the exterior design of the cover 1 emphasizes a smooth and harmonious shape. Its surface is finely treated, with smooth line transitions, completely abandoning the sharp-edged design style of traditional decorative covers. This design not only enhances the overall visual effect of the vehicle but also meets the aesthetic requirements of modern buses.

[0023] Preferably, a groove-shaped portion 10 is formed on the side of the air intake adapter box 3 away from the hexagonal grille 7. The cross-section of the groove-shaped portion 10 is trapezoidal, and the flange interface 6 is located inside the groove-shaped portion 10. In this way, with one side of the hexagonal grille 7 as the main air intake side, the groove-shaped portion 10 on the opposite side is adapted to receive the airflow, and is further provided with a trapezoidal shape that gradually increases in width towards the opening, which increases the airflow guiding effect and better guides the airflow to the flange interface 6, facilitating air intake.

[0024] Furthermore, a first louvered grille 11 is provided on the other side of the air intake adapter box 3. By adding the first louvered grille 11, the air intake flow is increased, airflow is guided, and external objects are blocked from entering the interior.

[0025] Furthermore, to address the potential water accumulation issue during rainy days, a drain outlet 12 is provided at the bottom of the trough section 10. The drain outlet 12 is used to connect to the drain pipe, facilitating the rapid drainage of water accumulated in the air intake adapter box 3. It should be noted that the flange interface 6 protrudes from the bottom of the air intake box to reduce the impact of water accumulation. Additionally, a proper seal is required after connecting the air intake pipe.

[0026] As one implementation method, the bottom of the air intake adapter box 3 is inclined, specifically inclined towards the drain outlet 12, to facilitate the drainage of accumulated water.

[0027] In one embodiment, the side of the cover 1 is provided with a second louver grille 13 that communicates with the exhaust chamber 4. The exhaust chamber 4 is mainly used for engine exhaust and houses the exhaust pipe, which is connected to the exhaust pipe outlet 8. Furthermore, the second louver grille 13 is provided around it. These second louver grilles can effectively dissipate the heat generated during the exhaust process, preventing heat accumulation from damaging the main body of the decorative cover. Also, in another embodiment, the bottom of the exhaust chamber 4 is open, allowing it to communicate with the vehicle interior, facilitating air circulation between the vehicle interior and the outside, and improving the air quality inside the vehicle.

[0028] This invention demonstrates significant technical advantages in practical applications. By integrating the air intake and exhaust functions into one unit, it not only improves space utilization but also simplifies the structural design of the vehicle roof. The top-mounted air intake design fully utilizes the higher air cleanliness at the top of the vehicle, ensuring cleaner air enters the engine and thus improving engine efficiency. The top-mounted exhaust design effectively reduces the impact of exhaust heat radiation and noise on pedestrians, improving their experience. The application of adhesive bonding not only enhances sealing performance but also avoids the risk of leakage that may arise from traditional self-tapping screw fixing methods. The overall design is smooth and harmonious, meeting the aesthetic requirements of modern buses and significantly improving the vehicle's appearance quality.

[0029] In summary, this utility model provides a highly integrated, well-sealed, and aesthetically pleasing roof-mounted decorative cover structure for buses. Its technical solution is applicable to the design of roof-mounted decorative covers for various types of buses, possessing broad application prospects and market value. By optimizing material selection, structural design, and fixing methods, this utility model successfully overcomes the shortcomings of traditional decorative covers in terms of functional integration, sealing, and appearance design, providing a completely new solution for the bus manufacturing industry.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
