Furthermore, the weight of the mounting components varies in different areas of the roof, and the structural strength requirements also differ at different locations.

[0003] In related technologies, the structural design of the top cover is not reasonable enough, and it is impossible to achieve a balance between structural strength, weight, and cost, resulting in a poor user experience. Utility Model Content

[0017] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0018] The following is for reference. Figures 1-2 The present invention describes a vehicle roof 100 according to an embodiment of the present invention. The vehicle roof 100 can be applied to the driver's cabin of the vehicle, and the driver's cabin of the vehicle can be applied to the vehicle.

[0019] Combination Figure 1 and Figure 2 As shown, the vehicle roof 100 according to this utility model mainly includes: a roof body 10. The roof body 10 may include: a first force-bearing part 11 and a second force-bearing part 12. The first force-bearing part 11 extends in the front-rear direction and is a first-density fiberglass part. There are two second force-bearing parts 12, each connected to one side of the first force-bearing part 11 in the left-right direction. The second force-bearing part 12 is a second-density fiberglass part. The density of the first-density fiberglass part is ρ1, and the density of the second-density fiberglass part is ρ2. ρ1 and ρ2 satisfy the relationship: ρ1 > ρ2.

[0020] Specifically, by extending the first force-bearing part 11 in the front-rear direction, and having two second force-bearing parts 12 connected to the left and right sides of the first force-bearing part 11 respectively, the basic structure of the vehicle's roof 100 can be formed. The roof 100 can be installed on top of the driver's cabin and seal the cabin. Optionally, to meet user needs, the roof 100 can be connected to and configured with various external components.

[0021] Considering the actual application scenarios of the vehicle's roof 100, the weight of its installation configuration varies in different areas of the roof 100. Specifically, the first load-bearing part 11 is located in the middle area of ​​the vehicle's roof 100, which is a non-load-bearing area or a non-critical load-bearing area. The first load-bearing part 11 is a non-top-pressure bearing surface, and the total weight of the external components installed therein is between 0-10kg, such as the installation areas for the roof, marker lights, intelligent connectivity, radar, and antennas. The second load-bearing part 12 is located in the edge area of ​​the vehicle's roof 100, which is a critical load-bearing area, and the total weight of the external components installed therein is over 10kg, such as the installation area for the roof cabinet. That is, compared to the second load-bearing part 12, the structural strength and load-bearing capacity requirements for the first load-bearing part 11 are lower.

[0022] Furthermore, fiberglass, or glass fiber reinforced plastic, is a composite material made of glass fibers and a matrix resin. Glass fibers possess high strength and high modulus, providing the main load-bearing capacity of the composite material, while the matrix resin serves to bind the fibers and transfer stress. By using a fiberglass top cover body 10, the top cover body 10 can resist deformation, preventing pressure from concentrating at a single localized point, thus avoiding damage caused by excessive localized pressure on the top cover body 10.

[0023] The performance of fiberglass reinforced plastic (FRP) is closely related to its density. Higher density FRP results in higher structural strength and load-bearing capacity. High density FRP can be achieved by increasing the glass fiber content or using high-modulus fibers, while low density FRP can be achieved by adjusting the resin formulation, such as adding lightweight fillers or changing the fiber distribution. No specific limitations are specified here.

[0024] By making the first load-bearing part 11 a first-density fiberglass part and the second load-bearing part 12 a second-density fiberglass part, and making the density of the second-density fiberglass part greater than the density of the first-density fiberglass part, the second load-bearing part 12 can have better structural strength and load-bearing capacity, so that the structural strength and load-bearing capacity of the second load-bearing part 12 can meet the usage requirements, and the first load-bearing part 11, under the premise that its structural strength and load-bearing capacity meet the usage requirements, has a lower weight due to its lower density.

[0025] In this way, the first load-bearing part 11 and the second load-bearing part 12 can each meet their load-bearing capacity requirements, making different areas of the top cover body 10 compatible with their application scenarios and avoiding situations of insufficient or excessive performance. Thus, while ensuring the structural strength and load-bearing capacity of the top cover body 10 and even the top cover 100, and ensuring their normal use, the weight of the top cover body 10 and even the top cover 100 can be reduced, improving the lightweight nature of the top cover body 10 and even the top cover 100.

[0026] Furthermore, by making the density of the second force-bearing part 12 lower, the excessive use of expensive high-performance materials can be avoided, reducing material costs. Thus, while ensuring the performance of the top cover body 10, the cost of the top cover body 10 and even the top cover 100 can be reduced.

[0027] Therefore, by making the first force-bearing part 11 a first-density fiberglass part and the second force-bearing part 12 a second-density fiberglass part, and making the density of the second-density fiberglass part greater than the density of the first-density fiberglass part, the performance of the first force-bearing part 11 and the second force-bearing part 12 can be adapted to their application scenarios, thereby achieving a balance between performance, weight, and cost of the vehicle's roof 100.

[0028] The density of the first density fiberglass component is ρ1, and ρ1 satisfies the relationship: 1.4 g / cm³. 3 ≤ρ1<1.9g / cm 3 This design not only avoids the first load-bearing part 11 from having insufficient performance due to excessively low density of the first density fiberglass component, but also avoids the first load-bearing part 11 from having excessively high density, resulting in excessive performance, weight, and cost. Therefore, the density of the first density fiberglass component can be set within a reasonable range, ensuring that the performance of the first load-bearing part 11 meets the usage requirements while reducing its weight and cost. Furthermore, this design also allows the first load-bearing part 11 to meet the requirements for heat insulation and sound insulation.

[0029] The density of the second density fiberglass component is ρ2, which satisfies the relationship: 1.9 g / cm³. 3 ≤ρ1≤2.5g / cm 3 This design not only avoids the second load-bearing part 12 from having insufficient density due to low density, but also avoids the second load-bearing part 12 from having excessive density due to high density. Therefore, the density of the second fiberglass part is set within a reasonable range, ensuring that the performance of the second load-bearing part 12 meets the usage requirements and guarantees its structural strength. Furthermore, this design also ensures that the second load-bearing part 12 meets the requirements for electromagnetic shielding. In some embodiments of this utility model, the top cover body 10 is a structural component integrally die-cast. Specifically, considering that the first force-bearing part 11 and the second force-bearing part 12 are fiberglass parts of different densities, by setting the top cover body 10 as a structural component integrally die-cast, it is possible not only to improve the connection strength and tightness between the first force-bearing part 11 and the second force-bearing part 12, improve the structural reliability of the top cover body 10, and improve the sealing performance of the top cover body 10, but also to simplify the processing steps and assembly process of the top cover body 10, reduce labor costs and equipment occupancy time, improve production efficiency, and reduce production costs.

[0030] Specifically, the process of integral die casting can include the following steps: S1: Prepare fiberglass raw materials of different densities, including different types and contents of glass fiber, resin, and various additives. S2: Accurately weigh the fiberglass raw materials of different densities according to the design requirements and mix them thoroughly in a specialized mixing device. It is necessary to ensure that the materials of different densities are evenly distributed, laying the foundation for the subsequent die casting of products with a specific density distribution. S3: Design and manufacture molds according to the shape and structure of the product. The mold cavity is equipped with multiple independent and precisely arranged material injection channels for injecting fiberglass mixtures of different densities. S4: Close the die casting machine. S5: Inject the glass mixtures of different densities into the mold cavity. S6: After the fiberglass solidifies, open the mold and remove the part. S7: Perform quality inspection on the removed integral die casting part. It should be noted that in S5, fiberglass preforms of different densities can also be injected into the mold cavity; this will not be elaborated here.

[0031] Furthermore, the vehicle's roof 100 may also include a protective coating applied to the upper surface of the roof body 10. Specifically, by applying the protective coating to the upper surface of the roof body 10, it not only protects the roof body 10 by preventing corrosion, UV aging, wear, and scratches, but also enhances the roof 100's appearance and visibility, thus improving the user experience. The protective coating is, but is not limited to, a paint layer.

[0032] Furthermore, considering the different flowability of fiberglass composites with different densities, flow marks may appear at the connection point between the first stress-bearing part 11 and the second stress-bearing part 12 after the top cover body 10 is integrally die-cast. Applying a protective coating to the upper surface of the top cover body 10 can conceal these marks, thereby further improving the refinement of the vehicle's top cover 100.

[0033] Combination Figure 2 As shown, a nut 20 is pre-embedded in the top cover body 10. There are multiple nuts 20, which are suitable for connecting with multiple external components.

[0034] Specifically, during the die-casting of the top cover body 10, multiple nuts 20 can be pre-embedded within the top cover body 10. These nuts 20 are at least partially disposed on the lower surface of the top cover body 10, thus ensuring stable placement of the nuts 20 within the top cover body 10. Furthermore, after the vehicle's top cover 100 is applied to the vehicle, the nuts 20 can be used to connect with multiple external components, facilitating the installation of these components on the top cover body 10 and meeting user needs. These external components include, but are not limited to, air deflectors, roof cabinets, canopies, marker lights, intelligent connectivity devices, radar, and antennas, and can be selected according to the actual scenario; no specific limitations are made here.

[0035] Optionally, a mounting bracket 30 can be provided, which is connected between the nut 20 and the external component. This facilitates the connection between the external component and the top cover body 10, improving the user experience.

[0036] Combination Figure 1 and Figure 2 As shown, the first force-bearing part 11 may mainly include: a first force-bearing body 111 and a first end cap 112. The first force-bearing body 111 is arc-shaped and extends in the front-rear direction. The first end cap 112 is connected to the rear end of the first force-bearing body 111 and extends downward.

[0037] With this configuration, the interconnected first force-bearing body 111 and first end cap 112 can form the basic structure of the first force-bearing part 11. The first force-bearing part 11 can be placed on the top of the cockpit. By making the first force-bearing body 111 arc-shaped, the resistance of the top cover 100 during vehicle movement can be reduced. By making the first end cap 112 extend in the vertical direction, it can be adapted to the structure of the first force-bearing body 111, thereby increasing the internal space of the cockpit while ensuring the sealing of the cockpit. Furthermore, combined Figure 1 and Figure 2 As shown, the second force-bearing part 12 may mainly include: a second force-bearing body 121, a second end cap 122, and a side plate 123. The second force-bearing body 121 is arc-shaped and extends in the front-rear direction. The second force-bearing body 121 is connected to the first force-bearing body 111 in the left-right direction. The second end cap 122 is connected to the rear end of the second force-bearing body 121 and extends downward. The second end cap 122 is connected to the first end cap 112 in the left-right direction. The side plate 123 is connected to the side of the second force-bearing body 121 away from the first force-bearing body 111 in the left-right direction and extends downward. With this configuration, the interconnected second force-bearing body 121, second end cap 122, and side plate 123 can form the basic structure of the second force-bearing part 12. The second force-bearing part 12 can be installed on the top of the cockpit. By making the second force-bearing body 121 arc-shaped, the resistance of the top cover 100 during driving can be reduced. By making the second end cap 122 and side plate 123 extend in the vertical direction, they can be adapted to the structure of the second force-bearing body 121, thereby increasing the internal space of the cockpit while ensuring the sealing of the cockpit.

[0038] In the above, by optimizing the structure of the first force-bearing part 11 and the second force-bearing part 12, the first force-bearing part 11 and the second force-bearing part 12 are connected to each other, thereby reducing the resistance of the top cover 100 during vehicle operation while ensuring the sealing of the top cover 100 to the driver's cabin.

[0039] The driver's cabin of a vehicle according to an embodiment of the present invention may include the aforementioned vehicle roof 100. Specifically, by applying the roof 100 to the driver's cabin of the vehicle, while ensuring that the driver's cabin can achieve normal installation and use of various components through the roof 100, not only can the weight be reduced, but the cost can also be reduced, thereby improving the user experience.

[0040] The vehicle according to an embodiment of this utility model may include: the driver's cab of the vehicle described above. Specifically, by applying the driver's cab to the vehicle, while meeting the normal use requirements, it is possible not only to reduce weight and achieve vehicle lightweighting, which helps improve fuel economy and driving range, but also to reduce costs and simplify the vehicle's production process, thereby enhancing the user experience and improving the vehicle's product competitiveness. The vehicle includes, but is not limited to, heavy-duty trucks, medium-duty trucks, light-duty trucks, mini-trucks, and pickup trucks.
