[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] The terms "top surface," "bottom surface," and "underside surface" refer to the normal use state of the top cover and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0027] like Figure 1-4 As shown, an integrated top guide cover includes a main body 1, a skylight 2 on the top surface of the main body 1, and the top surface of the main body 1 is streamlined along its length. A frame-shaped inner side panel 3 is provided on the inner side of the main body 1. The outer periphery of the inner side panel 3 is connected to the inner walls of the main body 1 by an adhesive layer. The top surface of the inner side panel 3 is detachably connected to a mounting base 102 by a connector. The mounting base 102 is fixedly connected to the main body 1.

[0028] The aforementioned top cover can be adapted and installed with heavy trucks. The top surface of the main body 1 of the top cover is designed with a streamlined structure, so that the main body 1 also functions as a fairing, realizing the integrated design of the top cover and the fairing. During vehicle operation, the streamlined structure of the top cover can reduce the vehicle's wind resistance, thereby reducing the vehicle's fuel consumption. Furthermore, after the vehicle is equipped with this top cover, there is no need to install an additional fairing, and there is no need to reserve mounting points on the top cover for installing the fairing, ensuring the consistency and integrity of the top cover surface.

[0029] After the inner side panel 3 is fixedly connected to the top cover through the adhesive layer, it can strengthen the top cover and improve its firmness. The connecting component is a bolt. After the mounting base 102 is fixedly connected to the inner side panel 3 through the connecting component, the strength of the connection between the top cover and the inner side panel 3 can be further improved. In addition, after the bolts fix the inner side panel 3 to the top cover during processing, they can play a pre-positioning role between the two. When the adhesive layer is applied, it can prevent displacement between the two, thereby improving the accuracy of the fixed connection and the accuracy of the assembly between the top cover and the vehicle body. The mounting base 102 is formed and set with the main body 1 and is connected to the inner side panel 3 from the top. It can provide vertical support and limit the connection between the top cover and the inner side panel 3. At the same time, the outer peripheral surface of the inner side panel 3 and the inner peripheral surface of the top cover form a horizontal limit, which can further improve the stability of the connection between the top cover and the inner side panel 3.

[0030] Further improvements include, for example Figure 5 As shown, the top surface of the inner side panel 3 has a positioning groove 301 that engages with the mounting base 102. After the mounting base 102 is inserted into the positioning groove 301, the two limit each other to achieve precise positioning between the inner side panel 3 and the top cover. Then, it is tightened with bolts, which can improve the installation accuracy between the top cover and the inner side panel 3.

[0031] Further improvements include, for example Figure 5 As shown, the top surface of the inner side panel 3 is provided with multiple second reinforcing ribs 302, each of which is located adjacent to the positioning groove 301. The second reinforcing ribs 302 strengthen the mounting part between the inner side panel 3 and the mounting base 102, thereby increasing the strength of the inner side panel 3 and the connection strength between the inner side panel 3 and the top cover, and thus improving the firmness of the top cover on the vehicle body.

[0032] Further improvements include, for example Figure 2 As shown, multiple first reinforcing ribs 101 are arranged in a crisscross pattern on the inner wall of the main body 1. The first reinforcing ribs 101 are distributed on the inner wall of the main body 1, which can effectively improve the structural strength, rigidity and stability of the top cover, thereby improving the protective performance of the top cover.

[0033] Further improvements include, for example Figure 3 As shown, multiple pre-installed mounting parts 103 are distributed on the inner wall of the main body 1. The pre-installed mounting parts 103 are U-shaped steel plates with threaded holes, which are welded to the inner wall of the top cover. This provides mounting points for the subsequent installation of other components on the top cover, thereby improving the ease of installation of various parts on the top cover.

[0034] Further improvements include, for example Figure 3As shown, a limiting part 104 is integrally formed on the main body 1, and the limiting part 104 is set adjacent to the reserved mounting part 103. The limiting part 104 is a protruding strip integrally formed with the top cover. For the reserved mounting part 103 installed on the inner top wall of the top cover, the limiting part 104 is provided around its perimeter. For the reserved mounting part 103 installed on the inner side wall of the top cover, the limiting part 104 is only installed on its upper and lower sides. The limiting part 104 can play a positioning role for the reserved mounting part 103, improve the accuracy of the installation position of the reserved mounting part 103, and at the same time, it can limit the sliding of the reserved mounting part 103, thereby improving its installation firmness.

[0035] Further improvements include, for example Figure 4 As shown, the inner side panel 3 has a U-shaped cross-section and is provided with mounting holes 304. The U-shaped cross-section enhances the bending resistance of the inner side panel 3, thereby improving its structural strength. Compared to existing inner side panel assemblies, this inner side panel 3 has a reduced vertical height and an increased horizontal width. Thus, the support of the mounting base 102 ensures the vertical installation strength of the inner side panel 3. Furthermore, when the roof is mounted on the vehicle body, the wider inner side panel 3 provides a larger contact area with the vehicle body, improving the connection strength between the inner side panel 3 and the vehicle body, and consequently, the connection strength between the roof and the vehicle body. The mounting holes 304 on the inner side panel 3 are used for connection with the vehicle body, improving the ease of connection between the inner side panel 3 and the vehicle body.

[0036] Further improvements include, for example Figure 6 As shown, the bottom surface of the inner side panel 3 is the bonding surface 303, and the adhesive layer is disposed on the bonding surface 303. When the top cover is installed on the vehicle body, the bonding surface 303 is bonded to the vehicle body, and the two form a vertical mutual restraint between them. The adhesive layer can further enhance the connection strength between the inner side panel 3 and the vehicle body, thereby improving the firmness of the top cover installation. At the same time, it can also play a sealing and waterproof role between the inner side panel 3 and the vehicle body, thereby improving the overall waterproof performance of the vehicle.

[0037] Further improvements include, for example Figure 6 As shown, the inner side panel 3 comprises multiple splicing segments, with adjacent splicing segments interlocking with each other. Specifically, each splicing segment is connected to the main body 1 via at least two mounting bases 102 to ensure the connection strength between it and the main body 1. The interlocking between adjacent splicing segments enhances the overall strength of the inner side panel 3, and applying adhesive at the interlocking points improves waterproof performance while ensuring connection strength. Dividing the inner side panel 3 into multiple splicing segments reduces production difficulty, minimizes space occupation during transportation, and allows for individual replacement during subsequent maintenance, reducing maintenance costs.
