[0016] The streamlined air guiding surface smoothly connects the arc bottom edge and the air guiding longitudinal edge, and the streamlined air guiding surface protrudes upward from an end away from the air guiding protrusion to an end close to the air guiding protrusion.

[0017] Optionally, in the above-mentioned car roof, the arc-shaped bottom edge is semicircular, and the streamlined air-guiding surface is a downwardly curved surface along the transverse direction of the vehicle.

[0018] Optionally, the above-mentioned car roof also includes a roof crossbeam, which is arranged at the bottom of the roof body along the transverse direction of the car body.

[0019] Optionally, the above-mentioned carriage roof further includes:

[0048] The following describes the embodiments of the present application. It should be noted that, in the specific description of these embodiments, in order to provide a concise description, this specification cannot provide a detailed description of all the features of the actual embodiments. It should be understood that in the actual implementation of any embodiment, in order to achieve specific goals, changes from one embodiment to another will occur. In addition, it is also understood that although the efforts made in this development process may be complex and lengthy, for ordinary technicians in the field related to the content of this application, some changes in design, manufacturing or production based on the technical content disclosed in this application are just conventional technical means and should not be understood as the content of this application being insufficient.

[0049] like Figures 1-8 As shown, the car roof provided in the embodiment of the present application includes a roof body 1; a plurality of wind guide protrusions 7, which are arranged in sequence on the top surface of the roof body 1 along the longitudinal direction of the vehicle, and the wind guide protrusions 7 extend along the transverse direction of the vehicle; the wind guide protrusions 7 include: a windward surface 71, located on the side of the wind guide protrusion 7 facing the front of the vehicle, the windward surface 71 is inclined upward from the front end to the rear end and from the position of the top plate body 1; a leeward surface 73, located on the side of the wind guide protrusion 7 facing away from the front of the vehicle, and the rear end of the leeward surface 73 is connected to the top plate body 1; a transition surface 72, smoothly connecting the rear end of the windward surface 71 and the front end of the leeward surface 73; wherein, the front end of the windward surface 71 is the end thereof close to the front of the vehicle, and the rear end of the windward surface 71 is the end thereof away from the front of the vehicle; the front end of the leeward surface 73 is the end thereof close to the front of the vehicle, and the rear end of the leeward surface 73 is the end thereof away from the front of the vehicle.

[0050] It should be noted that the vehicle transverse direction, i.e., the Y direction, is the width direction of the vehicle, i.e., the left-right direction; the vehicle longitudinal direction, i.e., the X direction, is the length direction of the vehicle, i.e., the front-rear direction.

[0051] The roof body 1 is the main exposed portion of the vehicle's roof, directly affecting the vehicle's aerodynamic performance and appearance. In the vehicle's roof provided in this embodiment, the windward surface 71 and transition surface 72 of the wind-guiding protrusion 7 form a gently convex, rounded-top wind-guiding surface from front to back. This arrangement allows airflow to adhere to the windward surface 71 and flow slowly upward along it to the transition surface 72, from which it then flows backward.

[0052] The windward surface 71 is inclined upward from front to rear, which can better guide the airflow; the transition surface 72 makes the top of the wind-guiding protrusion 7 transition smoothly, which can reduce the impact of the airflow and reduce the vortex at the rear; therefore, it can optimize the aerodynamic performance of the top of the car body, ensure that the airflow can smoothly bypass the top of the car body during high-speed driving, reduce airflow separation, and then reduce wind resistance, thereby reducing energy consumption and improving the operating efficiency of the vehicle; at the same time, it enhances the stability of the vehicle, reduces vibration during driving, improves noise problems, and enhances the driving experience.

[0053] In addition, this embodiment significantly reduces vehicle fuel consumption and operating costs by reducing wind resistance, while also reducing carbon emissions, meeting environmental protection requirements.

[0054] In some embodiments, the leeward surface 73 is inclined upward from the position of the top plate body 1 from the rear end to the front end. Figure 5 、 Figure 6 、 Figure 8 As shown, the leeward surface 73 is inclined downward from front to back, which can play a better buffering role on the air flow, and at the same time is conducive to guiding the air flow out of the front wind guide protrusion 7 to the rear wind guide protrusion 7; it can reduce the vortex between the wind guide protrusions 7 and further reduce wind resistance.

[0055] With such arrangement, the top surface formed by the windward surface 71 , the leeward surface 73 and the transition surface 72 of the wind-guiding protrusion 7 all adopts a streamlined design, thereby optimizing the airflow attachment state and reducing wind resistance.

[0056] In some embodiments, the acute angle formed by the windward surface 71 and the horizontal plane where the top surface of the top plate body 1 is located is smaller than the acute angle formed by the leeward surface 73 and the horizontal plane where the top surface of the top plate body 1 is located. Optionally, the acute angle formed by the windward surface 71 and the horizontal plane where the top surface of the top plate body 1 is located is 10°-12° smaller than the acute angle formed by the leeward surface 73 and the horizontal plane where the top surface of the top plate body 1 is located; in this way, the windward surface 71 is closer to the top plate body 1 and has a flatter surface, ensuring smoother airflow and better wind resistance reduction; the front-to-back dimensions occupied by the leeward surface 73 are smaller than those of the windward surface 71, which is more conducive to the backward flow of air. Figure 6 、 Figure 8 As shown, for example, the acute angle formed by the windward surface 71 and the horizontal plane where the top surface of the top plate body 1 is located is 15°, and the acute angle formed by the leeward surface 73 and the horizontal plane where the top surface of the top plate body 1 is located is 26°, and the difference between the two is 11°.

[0057] Optionally, the longitudinal dimension of the windward surface 71 along the vehicle is the same as the sum of the longitudinal dimensions of the leeward surface 73 and the transition surface 72 along the vehicle; this facilitates processing and occupies a more compact space.

[0058] In some embodiments, both ends of the wind-guiding protrusion 7 are connected to the top plate body 1 through a streamlined wind-guiding portion 8; the streamlined wind-guiding portion 8 includes a curved bottom edge 81, connecting the front end of the windward surface 71 and the rear end of the leeward surface 73, and the curved bottom edge 81 is connected to the top plate body 1; the wind-guiding longitudinal edge 83 extends longitudinally along the vehicle and is smoothly connected to the end of the wind-guiding protrusion 7, and the wind-guiding longitudinal edge 83 includes a windward section, a transition section and a leeward section. The windward section is backward and upwardly inclined from the position where the curved bottom edge 81 is connected to the front end of the windward surface 71, and the leeward section is forward and upwardly inclined from the position where the curved bottom edge 81 is connected to the rear end of the leeward surface 73, and the transition section smoothly connects the top of the windward section and the top of the leeward section and is lower than the transition surface 72; the streamlined wind-guiding surface 82 is smoothly connected to the curved bottom edge 81 and the wind-guiding longitudinal edge 83, and the streamlined wind-guiding surface 82 protrudes upward from the end away from the wind-guiding protrusion 7 to the end close to the wind-guiding protrusion 7.

[0059] like Figure 3 、 Figure 4 、 Figure 7 As shown, the two ends of the air-guiding protrusion 7 are smoothly connected to the top plate body 1 through a streamlined air-guiding portion 8 formed by an arc-shaped bottom edge 81, an air-guiding longitudinal edge 83 and a streamlined air-guiding surface 82, which can optimize the aerodynamic performance of the left and right ends of the car top, reduce airflow separation, and further reduce wind resistance.

[0060] With such a configuration, the air guide protrusion 7 and the positions where its two ends are connected to the top plate body 1 form a smooth surface curve with a natural transition arc, and the overall design presents a streamlined teardrop shape, imitating the flow characteristics of water droplets in nature, which can reduce the wind resistance of the air guide protrusion 7 and the two ends of the air guide protrusion 7, and further optimize the aerodynamic performance.

[0061] The streamlined air guide portion 8 can have a front-to-back length (i.e., the longitudinal dimension along the vehicle) of 150-180 mm, for example, 166 mm; a left-to-right length (i.e., the transverse dimension along the vehicle) of 75-90 mm, for example, 86 mm; and a height (i.e., the vertical dimension along the vehicle) of 20-30 mm, for example, 25 mm. Adjacent air guide protrusions 7 are spaced apart, with the top spacing being 200-230 mm, for example, 216 mm. This prevents the aerodynamic performance of the cabin roof from being affected by being too large or too small, effectively reducing wind resistance.

[0062] like Figure 7 As shown, in some embodiments, the arc bottom edge 81 is semicircular, with a regular and simple shape, which is convenient for molding. The streamlined wind guide surface 82 is a curved surface that bends downward along the transverse direction of the vehicle, as shown in FIG. Figure 5 As shown, it is closer to the top plate body 1, and the curved surface changes more gently, which is conducive to airflow, can optimize the aerodynamic performance of the left and right ends of the car top, and further reduce wind resistance.

[0063] In some embodiments, the car roof also includes a roof crossbeam 3, which is arranged at the bottom of the roof body 1 along the transverse direction of the car body. The roof crossbeam 3 serves as the core supporting structure of the car roof, supporting and fixing the roof body 1 to ensure the overall rigidity and stability of the car roof. Figure 1 、 Figure 2 As shown, there can be multiple roof cross beams 3, which are dispersedly arranged between two adjacent wind guide protrusions 7. For example, there are three roof cross beams 3, which are evenly distributed on the roof body 1 along the longitudinal direction of the vehicle.

[0064] In some embodiments, the carriage roof further comprises a front frame 6 connected to the front side of the roof body 1; a rear frame 4 connected to the rear side of the roof body 1; a left frame 2 connected to the left side of the roof body 1; and a right frame 5 connected to the right side of the roof body 1, with both ends of the roof crossbeam 3 connected to the left frame 2 and the right frame 5, respectively; wherein, two adjacent ones of the front frame 6, the left frame 2, the rear frame 4, and the right frame 5 are sealed. The outer surfaces of the front frame 6, the left frame 2, and the right frame 5 are all smooth transition surfaces 72 that smoothly connect the top surface of the roof body 1 with the outer side surfaces of the carriage side panels; the rear frame 4 includes an air guide plane that is flush with the top surface of the roof body 1.

[0065] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, the front frame 6 is located at the front end of the car roof, connecting the roof body 1 and the front structure of the car. The smooth transition surface 72 on the outer surface of the front frame 6 optimizes the airflow entry state, guides the airflow to smoothly enter the surface of the roof body 1, and reduces the impact of the airflow. The left frame 2 serves as the left boundary structure of the car roof, connecting the roof body 1 and the left side panel of the car, ensuring the side sealing and structural integrity of the car roof. The right frame 5 serves as the right boundary structure of the car roof, connecting the roof body 1 and the right side panel of the car; its function is the same as that of the left frame 2, ensuring the left-right symmetry and right-side sealing of the car roof. As shown Figure 7-Figure 8 As shown, the rear frame 4 is located at the rear end of the car roof, connecting the roof body 1 with the rear structure of the car. The air guide plane of the rear frame 4 is a smooth horizontal plane, which guides the airflow to flow out smoothly, reduces airflow separation and vortex, optimizes the airflow outflow state, and reduces noise.

[0066] The front frame 6, left frame 2, and rear frame 4 all feature streamlined, rounded transition surfaces 72 with large rounded or chamfered corners. This optimizes airflow, reduces airflow resistance, and prevents airflow interference from sharp edges. These three frames can be curved, or L-shaped, with a circular transition on the outer surface. The radius R of the rounded transition surface 72 can be 60 mm to 80 mm, effectively buffering airflow.

[0067] A water guide trough may also be provided at the rear end of the air guide plane of the rear frame 4 to guide the accumulated water on the top of the car roof to the left and right sides.

[0068] When the vehicle is driving, air enters the roof area of the vehicle from the front and flows smoothly along the front frame 6; then the air flows along the surface of the roof body 1 and passes through the air guide protrusions 7 to reduce airflow separation; finally, the airflow is guided to the rear of the vehicle and flows out smoothly along the rear frame 4 to reduce eddy currents and noise.

[0069] like Figure 9 The overall airflow diagram of the vehicle is shown in FIG. Figure 9 The wind resistance represented by red, yellow, green, light blue and dark blue decreases in sequence; the simulation experiment shows that the wind resistance on the top of the car roof is mostly dark blue, which has a small wind resistance and can reduce energy consumption while improving noise problems.

[0070] In some embodiments, the front frame 6, left frame 2, rear frame 4, and right frame 5 are all welded to the roof body 1, and any two adjacent frames are welded together. Thus, all four frames are welded to the roof body 1, and the four frames are also welded together, ensuring overall sealing and structural strength. During assembly, the four frames are threadedly connected to the corresponding side panels of the carriage, facilitating assembly and transportation of the carriage.

[0071] In some embodiments, the roof crossbeam 3 is welded to the roof body 1; its ends are respectively welded to the left side frame 2 and the right side frame 5. This arrangement ensures the connection strength between the roof crossbeam 3 and the roof body 1, as well as the overall structural strength of the vehicle roof.

[0072] This shows that the embodiments of the present application not only optimize the aerodynamic performance of the car roof, but also take into account the load-bearing performance, noise control, and aesthetics of the car roof, resulting in a more balanced overall performance and providing users with a more efficient, comfortable, and practical experience. Through strength calculations and durability testing, the car roof provided by the embodiments of the present application can ensure the structural strength and service life under various operating conditions (such as high-speed driving and inclement weather).

[0073] In some embodiments, the roof body 1, roof crossbeam 3, front frame 6, left frame 2, rear frame 4, and right frame 5 are all lightweight, high-strength steel components. This achieves a lightweight design for the vehicle roof, significantly reducing the weight of the vehicle roof, lowering the overall vehicle weight and improving fuel efficiency. For example, the roof body 1, roof crossbeam 3, front frame 6, left frame 2, rear frame 4, and right frame 5 are all made of a lightweight, high-strength material—BST700X steel plate. BST700X steel plate is a high-strength, low-alloy steel plate with excellent performance, featuring light weight, high strength, and corrosion resistance, achieving both lightweight and high strength.

[0074] In the above embodiment, the vehicle roof consists of six parts: a roof crossbeam 3, a roof body 1, a left frame 2, a right frame 5, a front frame 6 and a rear frame 4. Through the air guide structure at the top of the roof body 1 and the reasonable design and optimization of the materials of each component, the goals of lightweighting, optimizing aerodynamic performance, improving strength and ensuring sealing are achieved, providing an efficient and practical solution for vehicles such as light trucks and vans.

[0075] like Figure 1 、 Figure 2 As shown, an embodiment of the present application also provides a carriage, including carriage side panels and a carriage roof panel arranged on the top of the carriage side panels. The carriage roof panel is the carriage roof panel provided by any of the above embodiments, which can reduce wind resistance, thereby reducing energy consumption, and improving noise problems at the same time; its advantages are brought by the carriage roof panel. For details, please refer to the relevant parts in the above embodiments, and will not be repeated here.

[0076] The car roof can be screwed onto the top of the car side panels for easy assembly and transportation.

[0077] The side panels of the carriage consist of the front, rear, left, and right sides. The roof panel is welded together and then bolted to the front, rear, left, and right sides to ensure a tight seal between the roof and side panels, preventing rainwater, dust, and other debris from entering the carriage.

[0078] like Figure 9 As shown, the embodiment of the present application further provides a vehicle including the above-mentioned carriage, which can reduce wind resistance, thereby reducing energy consumption and improving noise problems. For example, the vehicle can be a light truck, a van, or a train.
