[0057] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0058] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0059] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0060] According to an embodiment of the present invention, in a first aspect, a vehicle body structure 1 is provided, the vehicle body structure 1 including a decorative cover plate 100, a first sealing element 151, a side panel assembly 200, an elastic sealing element 400, and a lidar 500.

[0061] The decorative cover plate 100 includes an outer plate 110 and a reinforcing plate 120, which are stacked in the z-direction. A first sealing member 151 is disposed between the outer plate 110 and the reinforcing plate 120, and is located on opposite sides of the decorative cover plate 100 in the y-direction. The z-direction and y-direction are intersecting, for example, the outer plate 110 and the reinforcing plate 120 together define a first mounting cavity 150, which is located on opposite sides of the decorative cover plate 100 in the y-direction, and the first sealing member 151 is disposed within the first mounting cavity 150. A side panel assembly 200 is located on opposite sides of the decorative cover plate 100 in the y-direction, and the first sealing member 151 is connected to the side panel assembly 200. A top cover beam 300 is located on the side of the reinforcing plate 120 facing away from the outer plate 110 in the z-direction, and is connected to the side panel assembly 200. The elastic seal 400 is disposed between the top cover beam 300 and the reinforcing plate 120, and the elastic seal 400 extends circumferentially along the decorative cover plate 100, that is, the elastic seal 400 is arranged around the circumference of the decorative cover plate 100.

[0062] The lidar 500 is located between the decorative cover plate 100 and the top cover crossbeam 300. The lidar 500 is connected to the decorative cover plate 100, or to the top cover crossbeam 300, or to both the decorative cover plate 100 and the top cover crossbeam 300. Alternatively, the lidar 500 can be first assembled onto the decorative cover plate 100, and then the lidar 500 and the decorative cover plate 100 can be assembled as a whole onto the top cover crossbeam 300.

[0063] Specifically, the y-direction is the left-right direction of the vehicle, and the z-direction is the height direction of the vehicle. The first mounting cavity 150 is located on the left and right sides of the decorative cover plate 100. There are two side panel assemblies 200, one located on the left side of the decorative cover plate 100 and the other located on the right side of the decorative cover plate 100. Furthermore, the outer panel 110 and the reinforcing plate 120 can be bonded together. The reinforcing plate 120 is located below the outer panel 110. The upper surface of the outer panel 110 is smoothly designed to improve the aesthetics of the vehicle body structure 1. The reinforcing plate 120 is used to strengthen the structural strength of the decorative cover plate 100. The top cover crossbeam 300 is located below the reinforcing plate 120. The top cover crossbeam 300 is connected to the side panel assembly 200 on both opposite sides along the y-direction. The top cover crossbeam 300 and the side panel assembly 200 can be welded together.

[0064] The first seal 151 may include sealant. The first seal 151 is sandwiched between the outer plate 110 and the reinforcing plate 120. The opposite sides of the reinforcing plate 120 in the y-direction can be recessed away from the outer plate 110, that is, the opposite sides of the reinforcing plate 120 in the y-direction can be recessed downward to form a first mounting cavity 150 between the reinforcing plate 120 and the outer plate 110. The first seal 151 is located in the first mounting cavity 150. The reinforcing plate 120 and the outer plate 110 can define the first seal. The position of component 151 in the z-direction and the large connection area between the first seal 151 and the decorative cover plate 100 are beneficial to improving the relative positional stability between the first seal 151 and the decorative cover plate 100. Furthermore, the first seal 151 is bonded to the side assembly 200 to seal the gap between the side assembly 200 and the decorative cover plate 100, preventing rainwater and other liquids from flowing into the vehicle body structure 1 through the gap between the side assembly 200 and the decorative cover plate 100. This results in a low failure probability and a better sealing effect.

[0065] The elastic seal 400 can be sealing foam. The elastic seal 400 is compressed between the top cover beam 300 and the reinforcing plate 120. The interference fit between the gap between the top cover beam 300 and the reinforcing plate 120 and the elastic seal 400 can be 3.5mm, so as to seal the gap between the top cover beam 300 and the reinforcing plate 120 and prevent rainwater and other liquids from entering between the top cover beam 300 and the reinforcing plate 120.

[0066] The resilient seal 400 and the first seal 151 are stacked in the z-direction, meaning that the projection of the first seal 151 and the projection of the resilient seal 400 at least partially overlap in a plane perpendicular to the z-direction. In this way, the cooperation of the first seal 151 and the resilient seal 400 effectively prevents liquid from flowing from the opposite sides of the decorative cover 100 in the y-direction into the vehicle body structure 1, thus increasing the sealing effect.

[0067] Furthermore, such as Figure 3 and Figure 4 As shown, the vehicle body structure 1 also includes a panoramic glass 600 and a second sealing member 161. The panoramic glass 600 is located on one side of the decorative cover plate 100 in the x-direction. The second sealing member 161 is disposed between the outer panel 110 and the reinforcing plate 120. The second sealing member 161 and the panoramic glass 600 are located on the same side of the decorative cover plate 100 in the x-direction, and the second sealing member 161 is connected to the panoramic glass 600. For example, the outer panel 110 and the reinforcing plate 120 together limit the formation of a second mounting cavity 160. The second mounting cavity 160 is located on one side of the decorative cover plate 100 in the x-direction and communicates with the first mounting cavity 150. The second sealing member 161 is disposed in the second mounting cavity 160, and is arranged in pairs in the z-direction, x-direction, and y-direction.

[0068] Specifically, the x-direction is the vehicle's longitudinal direction, the second mounting cavity 160 is located behind the decorative cover 100, and the panoramic glass 600 is also located behind the decorative cover 100. The first seal 151 and the second seal 161 can be integrally formed, or the first seal 151 and the second seal 161 can be connected to form an integral structure to ensure the sealing effect between the first seal 151 and the second seal 161.

[0069] The second seal 161 may include sealant. The second seal 161 is clamped between the outer panel 110 and the reinforcing plate 120. The reinforcing plate 120, on the side in the x-direction near the skylight glass 600, can be recessed away from the outer panel 110, i.e., the side of the reinforcing plate 120 in the x-direction near the skylight glass 600 can be recessed downwards to form a second mounting cavity 160 between the reinforcing plate 120 and the outer panel 110. The second seal 161 is located within the second mounting cavity 160. The outer panel 110 and the reinforcing plate 120 can... The second seal 161 is positioned in the z-direction, and the connection area between the second seal 161 and the decorative cover plate 100 is large, which helps to improve the relative positional stability between the second seal 161 and the decorative cover plate 100. Furthermore, the second seal 161 is bonded to the sunroof glass 600, sealing the gap between the sunroof glass 600 and the decorative cover plate 100, preventing rainwater and other liquids from flowing into the vehicle body structure 1 through the gap between the sunroof glass 600 and the decorative cover plate 100. This results in a low failure probability and a better sealing effect.

[0070] The elastic seal 400 and the second seal 161 are stacked in the z direction, that is, on a plane perpendicular to the z direction, the projection of the second seal 161 and the projection of the elastic seal 400 are at least partially overlapped. Through the cooperation of the second seal 161 and the elastic seal 400, liquid can be effectively prevented from flowing from the decorative cover plate 100 on the side near the sunroof glass 600 in the x direction into the vehicle body structure 1, thereby increasing the sealing effect.

[0071] In addition, the top cover beam 300 and the skylight glass 600 can be partially stacked in the z direction, that is, part of the top cover beam 300 is located below the skylight glass 600, and a sealing strip can be provided between the top cover beam 300 and the skylight glass 600.

[0072] Furthermore, such as Figure 3 and Figure 4 As shown, the vehicle body structure 1 also includes a windshield 700 and a third seal 710. The windshield 700 is located on the side of the decorative cover 100 facing away from the panoramic sunroof 600 in the x-direction, and the windshield 700 and the roof crossbeam 300 are partially stacked in the z-direction. The third seal 710 is disposed between the windshield 700 and the roof crossbeam 300, and the third seal 710 is connected to the decorative cover 100.

[0073] Specifically, the third seal 710 is capable of elastic deformation and is compressed between the windshield 700 and the roof beam 300. The interference fit between the gap between the windshield 700 and the roof beam 300 and the third seal 710 can be 2.5 mm. The windshield 700 is located on the front side of the decorative cover 100.

[0074] The third seal 710 seals the gap between the windshield 700 and the trim cover 100, preventing rainwater and other liquids from flowing into the vehicle body structure 1 through the gap. The cooperation of the third seal 710 and the elastic seal 400 effectively prevents liquid from flowing into the vehicle body structure 1 from the side of the trim cover 100 near the windshield 700 in the x-direction, thus increasing the sealing effect.

[0075] Because of manufacturing tolerances in parts production and assembly errors in the fit between parts during assembly, the above-mentioned waterproof structure (first seal 151, second seal 161, third seal 710 and elastic seal 400) has a certain probability of failure, and liquid may enter the cavity formed by the decorative cover 100 and the top cover beam 300. In order to prevent the liquid in the cavity from entering the passenger compartment through the top cover beam 300, the vehicle body structure 1 also has the following structure.

[0076] In some embodiments, such as Figure 5As shown, the elastic seal 400 is provided with a drain outlet 410. The drain outlet 410 is located on the side of the elastic seal 400 near the windshield 700 in the x direction, and the drain outlet 410 is located on opposite sides of the windshield 700 in the y direction. The cavity defined between the decorative cover plate 100 and the top cover beam 300 communicates with the drain outlet 410.

[0077] Typically, in the vehicle body structure 1, the roof beam 300 is gradually inclined downwards from rear to front along the x-direction. Liquid on the roof beam 300 flows forward along the decorative cover plate 100, accumulating near the elastic seal 400 close to the windshield 700. Since the height of the windshield 700 gradually decreases from the center to both ends along the y-direction, and the roof beam 300 is adapted to the shape of the windshield 700, its height also gradually decreases from the center to both ends along the y-direction. Therefore, liquid flows into both ends of the elastic seal 400 along the y-direction.

[0078] By setting up the drain outlet 410, most of the water on the top cover beam 300 can be drained, reducing the amount of liquid residue on the top cover beam 300, effectively preventing liquid from flowing into the passenger compartment, improving comfort and safety, and optimizing the user experience.

[0079] In some embodiments, such as Figure 3 , Figure 5 and Figure 7 As shown, the decorative cover 100 has a protrusion 170, which protrudes in the z-direction away from the roof crossbeam 300. The lidar 500 is located between the protrusion 170 and the roof crossbeam 300. The protrusion 170 has a through hole 171 on the side near the windshield 700 in the x-direction. The vehicle body structure 1 also includes a window 130 and a sealing ring 140. The window 130 is located on the protrusion 170 and covers the through hole 171. The sealing ring 140 is arranged around the through hole 171 and is clamped between the lidar 500 and the protrusion 170. The window 130 is transparent, and the lidar 500 can detect the surrounding environment of the vehicle through the window 130.

[0080] Specifically, the lidar 500 can be installed on the side of the protrusion 170 near the windshield 700. For example, the lidar 500 is installed on the side of the protrusion 170 near the windshield 700 by a plurality of first mounting bolts 530, the first mounting bolts 530 extending in the x direction and the plurality of first mounting bolts 530 being spaced apart in the y direction. The rear end of the lidar 500 is installed on the decorative cover plate 100 by a second mounting bolt 540, the second mounting bolt 540 extending in the z direction.

[0081] The sealing ring 140 can be made of foam. The sealing ring 140 is clamped and compressed between the flange of the lidar 500 and the decorative cover plate 100 to prevent liquid from entering the decorative cover plate 100 through the gap between the window 130 and the decorative cover plate 100, thereby preventing the liquid from entering the vehicle body structure 1.

[0082] In some embodiments, such as Figure 4 As shown, the vehicle body structure 1 also includes a first hole seal 830 and a first fixing component 800.

[0083] The first hole seal 830 is disposed between the reinforcing plate 120 and the top cover beam 300. The first fixing component 800 includes a first threaded component 810 and a first nut 820. The first threaded component 810 passes through the reinforcing plate 120, the first hole seal 830, and the top cover beam 300 in sequence. The first nut 820 is connected to the first threaded component 810 and is located on the side of the top cover beam 300 facing away from the reinforcing plate 120. There can be multiple first fixing components 800, which are arranged at intervals along the x-direction. There are also multiple first hole seals 830, with multiple first threaded components 810 passing through multiple first hole seals 830 one by one.

[0084] Specifically, the first hole seal 830 can be made of foam, and the first threaded part 810 can be a bolt. After the first threaded part 810 is connected to the first nut 820, the reinforcing plate 120 and the top cover beam 300 clamp and compress the first hole seal 830. The first hole seal 830 can seal the hole on the top cover beam 300 through which the first threaded part 810 passes, so as to prevent liquid from entering the passenger compartment through the hole on the top cover beam 300 through the first threaded part 810, thereby improving the sealing effect of the vehicle body structure 1.

[0085] In addition, since the top cover beam 300 gradually decreases from back to front along the x-direction, the liquid will flow forward along the top cover beam 300 and will not accumulate on the top cover beam 300 and pass through the hole of the first threaded part 810, thereby reducing the probability of liquid flowing into the crew compartment.

[0086] In some embodiments, such as Figure 7 As shown, the top cover beam 300 is provided with welding positioning holes 320, and a second hole seal 330 is connected to the top cover beam 300. The second hole seal 330 seals the welding positioning holes 320. The second hole seal 330 may include at least one of a rubber plug and a sealing patch. Furthermore, there may be multiple welding positioning holes 320 spaced apart, and there may also be multiple second hole seals 330, with each of the multiple second hole seals 330 correspondingly sealing the multiple welding positioning holes 320.

[0087] This prevents liquid from entering the passenger compartment through the welding positioning hole 320, thus improving the sealing effect of the vehicle body structure 1.

[0088] In some embodiments, such as Figure 1 , Figure 7 and Figure 8 As shown, the lidar 500 is connected to a wiring harness 510, and a rubber sleeve 520 is fitted onto the outer periphery of the wiring harness 510. The top cover beam 300 has a through hole 310, through which the wiring harness 510 passes, and the rubber sleeve 520 is interference-fitted with the through hole 310. The rubber sleeve 520 can be supported by a soft rubber material, and the rubber sleeve 520 is made of soft rubber.

[0089] By setting the rubber sleeve 520, the gap between the inner circumferential surface of the sealing wire harness 510 and the through hole 310 is sealed, preventing liquid between the decorative cover plate 100 and the top cover beam 300 from entering the passenger compartment through the through hole 310, thereby improving the sealing effect of the vehicle body structure 1.

[0090] In some embodiments, such as Figure 8 and Figure 9 As shown, the vehicle body structure 1 also includes a bracket 900, a waterproof pad 910, and a second fixing component 920.

[0091] The bracket 900 is connected to the lidar 500, and the waterproof pad 910 is located between the bracket 900 and the top cover beam 300. The second fixing component 920 includes a second threaded member 921 and a second nut 922. The second threaded member 921 is sequentially inserted through the top cover beam 300, the waterproof pad 910, and the bracket 900. The second nut 922 is connected to the second threaded member 921 and is located on the side of the bracket 900 facing away from the top cover beam 300.

[0092] The bracket 900 is first assembled with the lidar 500 and the decorative cover plate 100, and then installed as a whole onto the top cover beam 300. The bracket 900 and the lidar 500 can be connected by a third mounting bolt 550.

[0093] Specifically, the second nut 922 can be a waterproof nut, and the second nut 922 is welded to the bracket 900. The waterproof gasket 910 is bonded to one side of the bracket 900 facing the top cover beam 300. The waterproof gasket 910 is fitted to the top cover beam 300. The second threaded part 921 can be a bolt. The second threaded part 921 passes through the top cover beam 300 and the waterproof gasket 910 from bottom to top along the z direction, and then is threaded to the second nut 922. At this time, the top cover beam 300 and the bracket 900 clamp the waterproof gasket 910. The waterproof gasket 910 can seal the gap between the bracket 900 and the top cover beam 300, preventing liquid from entering the passenger compartment from the hole in the top cover beam 300 through which the second threaded part 921 passes, thereby improving the sealing effect of the vehicle body structure 1.
