Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicles, in particular to a covering strip, a covering strip assembly and a vehicle. BACKGROUND

[0002] At present, vehicles are becoming more and more popular, and the appearance of vehicles is changing more and more, and the design is becoming more and more diverse. In the manufacturing process of the vehicle, there will be a gap when the multiple body panels of the vehicle are assembled, or there will be a gap when the vehicle window is connected to the vehicle body. In order to ensure the appearance quality of the vehicle and reduce the gap that causes wind noise during driving, a covering strip is usually arranged at the gap position. The covering strip can fill the gap of the vehicle, thereby reducing wind noise.

[0003] The existing covering strip is unstable in connection with the vehicle body, and noise will be generated between the covering strip and the vehicle body during driving, affecting the user's experience. SUMMARY

[0004] Based on this, the present application provides a covering strip, a covering strip assembly and a vehicle, which can solve the problem of unstable connection between the covering strip and the vehicle body during driving.

[0005] In a first aspect, the present application provides a covering strip for filling a gap between a first exterior trim and a second exterior trim, the covering strip comprising a connecting segment and a contact segment, the connecting segment comprising a first end and a second end, the first end being connected with the first exterior trim, the second end extending to the second exterior trim, the second end comprising a first surface, the first surface being opposite to a surface of the second exterior trim facing the vehicle interior, the contact segment being connected with the second end by bending, the contact segment extending from the first surface to a direction close to the first exterior trim, an included angle between the contact segment and the first surface being an acute angle, and an end of the contact segment away from the connecting segment being used for lap joint with a surface of the second exterior trim close to the vehicle interior.

[0006] It can be understood that the gap between the second exterior trim and the first exterior trim will reduce the appearance effect of the vehicle, and the airflow formed in the gap will also produce noise. The use of the covering strip to connect the first exterior trim and the second exterior trim can reduce wind noise. In the driving state, the airflow during the movement of the vehicle can flow along the connecting segment, and the airflow can pass through the connecting portion between the connecting segment and the contact segment and then flow to the contact segment and apply force to the contact segment. The contact segment receives the force generated by the rebound airflow and transmits the force, thereby generating pressure on the second exterior trim. Therefore, in the driving process, the contact segment will not vibrate and hit the second exterior trim due to the impact of the airflow, and the stable connection between the contact segment and the second exterior trim can reduce the noise between the covering strip and the second exterior trim during driving, thereby improving the user's riding experience.

[0007] In a possible implementation, the connecting section is connected to a side of the first exterior trim facing the interior of the vehicle, and the contact section is connected to a side of the second exterior trim facing the interior of the vehicle.

[0008] In a possible implementation, the connecting section includes a first connecting section and a second connecting section, the first connecting section is connected to the first exterior trim, and the second connecting section is connected between the first connecting section and the contact section, the hardness of the first connecting section and the hardness of the second connecting section are different.

[0009] In a possible implementation, the hardness of the second connecting section is the same as the hardness of the contact section.

[0010] In a possible implementation, the hardness of the first connecting section is in a range of HA70°-90°, and the hardness of the contact section and the second connecting section is in a range of HA50°-60°.

[0011] In a possible implementation, the connecting section includes a first connecting section and a second connecting section, the first connecting section is used to be connected to the first exterior trim, the second connecting section is connected between the first connecting section and the contact section, the hardness of the first connecting section is the same as the hardness of the second connecting section, and the hardness of the contact section is different from the hardness of the second connecting section.

[0012] In a possible implementation, the hardness of the first connecting section and the second connecting section is in a range of HA70°-90°, and the hardness of the contact section is in a range of HA50°-60°.

[0013] In a possible implementation, the centers of curvature of the first connecting section and the second connecting section are located on the same side or different sides of the trim strip.

[0014] It can be understood that the curved shapes of the first connecting section and the second connecting section affect the direction of airflow on the trim strip and the direction and size of the force of the airflow on the trim strip.

[0015] In a possible implementation, the connecting section is provided with a plurality of through holes, the plurality of through holes are arranged at intervals along the length direction of the trim strip, and the plurality of through holes are located in the gap between the first exterior trim and the second exterior trim.

[0016] It can be understood that the through holes can reduce the force of the airflow on the trim strip during driving of the vehicle, so that the trim strip cannot be stably overlapped with the second exterior trim due to excessive wind resistance, and noise caused by the trim strip hitting the second exterior trim during driving is avoided.

[0017] In a possible implementation, the second end of the connecting section comprises an edge end surface and the first surface connected with the edge end surface, and the contact section is connected to the first surface and has a spacing from the edge end surface; or the contact section is connected to both the first surface and the edge end surface.

[0018] It can be understood that the contact section arranged in the middle of the main structure can flexibly adjust the distance between the contact section and the first outer trim 210, that is, this implementation is suitable for the case that the edge of the second outer trim is close to the edge of the first outer trim.

[0019] In a possible implementation, the first connecting section forms the main structure, and the main structure comprises a core layer and an outer layer, and the outer layer is wrapped around the core layer; or the first connecting section and the second connecting section are connected to form the main structure, and the main structure comprises a core layer and an outer layer, and the outer layer is wrapped around the core layer.

[0020] It can be understood that the main structure can comprise a core layer of an aluminum strip, a copper wire or the like, and the core layer can improve the strength of the main structure and make the structure more stable.

[0021] In a possible implementation, the contact section comprises a cover plate contact surface, and the cover plate contact surface is provided with a friction reduction layer for contacting the luggage cover plate.

[0022] It can be understood that reducing the friction between the contact section and the second outer trim can not only reduce the noise caused by the friction between the contact section and the second outer trim, but also reduce the damage to the electrophoretic paint surface of the second outer trim, thereby improving the user experience and protecting the appearance of the vehicle.

[0023] In a second aspect, the application further provides a trim strip assembly comprising a first outer trim and the trim strip as described above, and the trim strip is connected to the first outer trim.

[0024] In a third aspect, the application further provides a vehicle comprising a second outer trim and the trim strip assembly as described above, and the trim strip assembly is connected to the second outer trim close to the inside of the vehicle.

[0025] In a possible implementation, the first outer trim is a windshield of the vehicle, and the second outer trim is a luggage cover plate of the vehicle. BRIEF DESCRIPTION OF DRAWINGS

[0035] The specific embodiments of the present application will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can also be implemented in other ways different from those described herein, and therefore the present application is not limited to the following embodiments.

[0036] For the convenience of understanding, the terms involved in the embodiments of the present application will be explained first.

[0037] Multiple: refers to two or more than two.

[0038] Connection: should be understood broadly, for example, A and B are connected, which can be that A and B are directly connected, or A and B are indirectly connected through an intermediate medium.

[0039] At present, vehicles are more and more popular, and the appearance of vehicles changes more and more, and the design is more and more diverse. In the manufacturing process of the vehicle, there is a gap between the spliced and assembled multiple body panels of the vehicle, or the connection position of the vehicle window connected to the vehicle body also generally has a gap. In order to ensure the appearance quality of the vehicle and reduce the existence of the gap to cause wind noise when driving, a trim strip is usually arranged at the gap position. The trim strip can fill the gap of the vehicle, thereby reducing wind noise.

[0040] The existing trim strip is unstable in connection with the vehicle body when filling the gap. In the driving process of the vehicle, noise is generated, which affects the user experience.

[0041] The application takes the connection between the windshield and the trunk cover plate as an example to introduce the structure of the trim strip and the connection mode thereof. It should be understood that the trim strip provided by the application is not only used between the windshield and the trunk cover plate, but also can be applied between other gaps existing in the vehicle body, such as the gap generated when multiple body panels are spliced and installed.

[0042] Since the trim strip is generally fixedly connected to the windshield, in the vehicle assembly process, the windshield and the trim strip arranged at the edge of the windshield are generally installed first, and then the trunk cover plate is installed. The trunk cover plate is overlapped on the trim strip to form a certain overlap force, so that the trim strip fills the gap between the windshield and the trunk cover plate. However, in the driving process of the vehicle, due to the driving airflow, the trim strip is pressed downward, thereby causing the trim strip to vibrate, causing the trim strip to hit the trunk cover plate and generate abnormal noise.

[0043] Based on this, the application provides a trim strip, a trim strip assembly and a vehicle, which can solve the problem of noise generated between the first exterior trim and the second exterior trim during driving.

[0044] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the vehicle 1000 provided by the embodiment of the application is shown. The vehicle 1000 includes a vehicle body 100 and a trim strip assembly 200, and the trim strip assembly 200 is connected to the vehicle body 100.

[0045] It should be noted that Figure 1 The purpose is only to schematically describe the connection relationship between the vehicle body 100 and the trim strip assembly 200, and not to specifically limit the connection position, specific structure and quantity of each device. The structure shown in the embodiment of the application does not constitute a specific limitation on the vehicle 1000. In other embodiments of the application, the vehicle 1000 can include more or fewer components than shown, or combine certain components, or split certain components, or different component arrangements. The components shown can be implemented in hardware, software or a combination of software and hardware.

[0046] The vehicle body 100 can include a vehicle body panel 110 and a second exterior trim 120. The vehicle body panel is further provided with an opening 111 and a receiving space (not shown in the figure), and the opening 111 is used to connect with the edge covering strip assembly 200. The second exterior trim can be understood as a trunk lid, and the second exterior trim 120 covers the receiving space of the vehicle body panel 110 to form a closed space. The second exterior trim 120 can be lifted from the vehicle body panel 110 to make the receiving space communicate with the external environment, or the second exterior trim 120 can also be lowered to the vehicle body panel 110 to close the receiving space, and isolate the receiving space from the external environment.

[0047] Please refer to Figure 1 and Figure 2 , Figure 2 is a structure schematic diagram of the edge covering strip assembly 200 and the vehicle body 100 before and after lapping provided by the embodiment of the present application, Figure 2 2a in the middle is a structure schematic diagram of the edge covering strip assembly 200 and the second exterior trim 120 when the second exterior trim 120 is not installed on the vehicle body panel 110, Figure 2 2b in the middle is a structure schematic diagram of the edge covering strip assembly 200 and the second exterior trim 120 after the second exterior trim 120 closes the receiving space of the vehicle body panel 110.

[0048] The edge covering strip assembly 200 includes a first exterior trim 210 and an edge covering strip 220. The first exterior trim can be a windshield, and one side of the edge covering strip 220 is fixedly connected with the side edge of the first exterior trim 210 close to the second exterior trim 120. Specifically, Figure 2 2a in the middle, after the first exterior trim 210 covers the opening 111, there is a gap between the first exterior trim 210 and the vehicle body panel 110, one side of the edge covering strip 220 is arranged in the gap between the edge of the first exterior trim 210 and the vehicle body panel 110, and is connected with the vehicle body panel 110 and the first exterior trim 210 through a colloid. As Figure 2 2b in the middle, after the second exterior trim 120 covers the vehicle body panel 110, the other side of the edge covering strip 220 is lapped with the second exterior trim 120 close to the vehicle body panel 110, so as to fill the gap between the first exterior trim 210 and the second exterior trim 120.

[0049] It can be understood that the gap between the second exterior trim 120 and the first exterior trim 210 will affect the visual perception of the user to the appearance of the vehicle 1000, and the airflow formed in the gap will also produce noise. The use of the edge covering strip 220 to connect the first exterior trim 210 and the second exterior trim 120 can reduce the wind noise generated during driving and improve the driving or riding experience of the user.

[0050] The first outer trim 210 can be single-layer glass or laminated glass composed of multiple layers of glass and an intermediate layer. The first outer trim 210 can be flat glass or curved glass. The first outer trim 210 can be the front windshield or the rear windshield of the vehicle 1000. The present application does not limit it. It should be noted that the side of the first outer trim 210 close to the second outer trim 120 can be curved, and the edge of the curved side is connected to the edge of the beading strip 220. The two ends of the beading strip 220 of the vehicle 1000 in the extension direction can extend beyond the second outer trim 120, so that the beading strip 220 can fill the gap between the second outer trim 120 and the first outer trim 210 in a larger range.

[0051] Please also refer to Figure 2 The beading strip 220 includes a connecting section 221 and a contact section 222. The connecting section 221 includes a first end (not labeled in the figure) and a second end (not labeled in the figure). The first end is connected to the first outer trim 210, and the second end extends to the second outer trim 120. The second end includes a first surface (not labeled in the figure), which is opposite to the surface of the second outer trim 120 facing the vehicle interior. The contact section 222 is connected to the second end by bending. The contact section 222 extends from the first surface to the direction close to the first outer trim 210. The included angle between the contact section 222 and the first surface is an acute angle. The end of the contact section 222 away from the connecting section 221 is used to lap the surface of the second outer trim 120 close to the vehicle interior. Specifically, the connecting section 221 and the contact section 222 are in the shape of a strip and are arranged along the edge of the first outer trim 210 close to the second outer trim 120. The first connecting section 221a and the second connecting section 221b are connected by bending. The second connecting section 221b is connected to the contact section 222 by bending. The included angle between the first connecting section 221a and the second connecting section 221b is an obtuse angle. The included angle between the second connecting section 221b and the contact section 222 is an acute angle. In the state that the second outer trim 120 is crimped to the beading strip 220, the included angle a between the contact section 222 and the connecting section 221 can be in the range of 30°-60° (including the end point values 30° and 60°). It should be noted that the included angle between the contact section 222 and the connecting section 221 is the included angle of the beading strip 220 facing the outside of the vehicle. The extension direction of the connecting section 221 is the direction in which the beading strip 220 is arranged along the edge of the first outer trim 210.

[0052] In the driving state, the airflow when the vehicle 1000 is moving can flow along the connecting section 221. The airflow can change direction through the included angle a between the connecting section 221 and the contact section 222 and then act on the contact section 222, and apply a force to the contact section 222. The contact section 222 receives the force generated by the rebound airflow and transmits the force, thereby generating pressure on the second outer trim 120.

[0053] It can be understood that under the action of the airflow, the contact section 222 is in close contact with the second outer trim 120, and in the driving process, the contact section 222 will not vibrate and beat the second outer trim 120 due to the impact of the airflow. The stable connection between the contact section 222 and the second outer trim 120 can reduce the noise between the edge cover strip 220 and the second outer trim 120 in the driving process, thereby improving the user's riding experience.

[0054] The connection section 221 further comprises a plurality of through holes 300, which are arranged at intervals along the length direction of the edge cover strip, and the plurality of through holes are located in the gap between the first outer trim 210 and the second outer trim 120. The through holes 300 are arranged at intervals along the extension direction of the edge cover strip 220. For example, the diameter of the through hole 300 is between 4mm-6mm (including the end point values 4mm and 6mm), and the diameter of the through hole 300 is not greater than the distance between the first outer trim 210 and the second outer trim 120. The number of through holes 300 is selected according to the length of the edge cover strip 220, and one through hole 300 can be arranged every 40mm-60mm on the edge cover strip 220.

[0055] It can be understood that the through holes 300 can be used for airflow to pass through, thereby reducing the force of the airflow generated during the driving of the vehicle 1000 on the edge cover strip 220, so that the edge cover strip 220 will not be unable to be stably overlapped with the second outer trim 120 due to excessive wind resistance, and noise caused by the edge cover strip 220 beating the second outer trim 120 in the driving process is avoided.

[0056] Please refer to Figure 2 , the connection section 221 comprises a first connection section 221a and a second connection section 221b, the first connection section 221a is connected with the first outer trim 210, and the second connection section 221b is connected between the first connection section 221a and the contact section 222. The second connection section 221b is bently connected with the contact section 222, and the included angle between the second connection section 221b and the contact section 222 is an acute angle. The acute angle mentioned here is the included angle a between the connection section 221 and the contact section 222 mentioned above.

[0057] The contact section 222 and the second outer trim 120 can generate a certain overlap force through the deformation of the contact section 222. The overlap force is the force exerted by the contact section 222 on the second outer trim 120. The value of the overlap force between the contact section 222 and the second outer trim 120 can be in the range of 5N / 100mm-10N / 100mm (including the end point values 5N / 100mm and 10N / 100mm).

[0058] It should be noted that the first outer trim 210 can be plate-shaped, including an edge end surface and two opposite surfaces, the first end of the connecting section 221 can be connected with the edge end surface of the first outer trim 210, or the first end is connected with a surface of the first outer trim 210 facing the vehicle interior, or the first end is connected with a surface of the first outer trim 210 away from the vehicle interior.

[0059] In a possible embodiment, as shown in Figure 2 , the first end of the connecting section 221 is connected with the surface of the first outer trim 210 close to the vehicle interior, and the contact section 222 is overlapped with the surface of the second outer trim 120 close to the vehicle interior. Please refer to Figure 3 and Figure 4 , Figure 3 is a structural schematic view of the edge end surface of the first outer trim 210 connected with the connecting section 221 and overlapped with the vehicle body 100, Figure 4 is a structural schematic view of the edge end surface of the first outer trim 210 connected with the connecting section 221 and overlapped with the vehicle body 100. In another possible embodiment, as shown in Figure 3 , the first end of the connecting section 221 is connected with the surface of the first outer trim 210 away from the vehicle interior, and the contact section 222 is overlapped with the surface of the second outer trim 120 close to the vehicle interior. In another possible embodiment, the first end of the connecting section 221 is connected with the edge end surface of the first outer trim 210, and the contact section 222 is overlapped with the surface of the second outer trim 120 close to the vehicle interior. Please refer to Figure 5 , Figure 5 is a structural schematic view of the edge end surface of the first outer trim 210 connected with the connecting section 221 and overlapped with the vehicle body 100,

[0060] The contact section 222 can be one or multiple. When the number of the contact sections 222 is multiple, the multiple contact sections 222 can be arranged along the width direction of the connecting section 221, and the multiple contact sections 222 are connected to and extend from the surface of the connecting section 221. The multiple contact sections 222 can be parallel to each other. The heights of the multiple contact sections 222 can be different, and the heights of the contact sections 222 can decrease successively from the end of the connecting section 221 away from the first exterior trim 210 to the other end of the connecting section 221 close to the first exterior trim 210. The height direction of the contact section 222 is the height of the contact section 222 extending from the connecting section 221.

[0061] It can be understood that when the number of the contact sections 222 is multiple, the multiple contact sections 222 can all be overlapped with the second exterior trim 120, which can make the overlapping of the edge covering strip 220 and the second exterior trim 120 more stable, and the multiple contact sections 222 can share the overlapping force applied by the edge covering strip 220 to the second exterior trim 120, so that the overlapping part of the second exterior trim 120 and the contact section 222 is not subjected to too concentrated force, and the noise caused by the large friction force between the contact section 222 and the second exterior trim 120 is avoided. The overlapping of the multiple contact sections 222 and the second exterior trim 120 can make the gap between the first exterior trim 210 and the second exterior trim 120 more difficult to be invaded by rain or dust. The close connection of the edge covering strip 220 and the second exterior trim 120 can also greatly avoid the noise caused by the edge covering strip 220 hitting the second exterior trim 120 due to shaking during driving.

[0062] Since the contact section 222 is partially depressed after being overlapped by the second exterior trim 120, that is, the distance between the position of each point on the connecting section 221 and the second exterior trim 120 gradually decreases in the direction close to the first exterior trim 210. Therefore, the heights of the multiple contact sections 222 successively decreasing can better adapt to the distance between the connecting section 221 and the second exterior trim 120, so that each contact section 222 can better overlap with the second exterior trim 120.

[0063] In the first possible implementation, please refer to Figure 2In the middle 2b, the first connecting section 221a and the second connecting section 221b are connected to form a main body structure, and the contact section 222 is separately formed as a lip structure. The hardness of the first connecting section 221a and the hardness of the second connecting section 221b are the same, and the hardness of the contact section 222 is different from the hardness of the second connecting section 221b. Specifically, the hardness of the first connecting section 221a and the second connecting section 221b ranges between HA70°-90°, and the hardness of the contact section 222 ranges between HA50°-60°. The curvature centers of the first connecting section 221a and the second connecting section 221b are on different sides of the trim strip, and the contact surface is connected to the first surface of the second end and the edge surface of the second end. The main body structure includes a plurality of through holes 300 arranged at intervals along the extension direction thereof, and the through holes 300 are located between the first outer trim 210 and the second outer trim 120. The main body structure further includes a core 2211 and an outer portion 2212, and the outer portion 2212 covers the core 2211 to form the main body structure. The material of the core 2211 can include aluminum strips, copper wires, or glass fibers and the like.

[0064] In this embodiment, the lip structure is arranged on one side of the main body structure and extends from the surface of the main body structure. One side of the main body structure is connected to the first outer trim 210, the other side of the main body structure is connected to the lip structure, and the other side of the lip structure away from the main body structure is overlapped with the second outer trim 120. The lip structure is deformed to fit the surface edge of the second outer trim 120 towards the vehicle body, so that the gap between the edge of the first outer trim 210 and the second outer trim 120 is filled by the trim strip 220.

[0065] It can be understood that the curvature centers of the first connecting section 221a and the second connecting section 221b are arranged on different sides of the trim strip 220, and in the side view perpendicular to the extension direction of the trim strip 220, the first connecting section 221a and the second connecting section 221b can be two smooth connecting arcs with the curvature centers not on one side, and the shape formed by the two end arcs is similar to S shape. Under this arrangement, the connecting section 221 can divert the airflow, a part of the airflow can flow out from the through hole 300, and a part of the airflow can act on the lip structure to make the lip structure tightly contact with the second outer trim 120, avoiding the trim strip 220 hitting the second outer trim 120. The core 2211 can effectively reduce the thermal expansion and contraction of the main body structure, so that the trim strip 220 will not deform too much at different temperatures and affect the structural stability of the trim strip 220.

[0066] The main body structure and the lip structure are made of materials that can be elastically deformed, wherein the hardness of the main body structure is greater than that of the lip structure, specifically, the hardness of the main body structure can be in the range of HA70°-90° (including the end values 70° and 90°), and the material of the main body structure can be thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), polyvinyl chloride (PVC), etc., wherein the TPE or EPDM can make the main body structure have better wear resistance and fatigue resistance.

[0067] The lip structure is made of foamed material with a smaller hardness value, which can better overlap with the second exterior part 120 through material deformation, and the density of the material of the lip structure can be in the range of 0.6g / cm 3 -0.9g / cm 3 , including the end values (0.6g / cm 3 -0.9g / cm 3 ). The hardness of the lip structure can be in the range of HA50°-60° (including the end values 50° and 60°). The material of the lip structure can be the same as that of the main body structure, such as TPE or foamed EPDM.

[0068] It can be understood that since the end of the lip structure away from the main body structure faces the first exterior part 210, and during the driving of the vehicle 1000, the pressure generated by the airflow acts on the flexible lip structure, part of the airflow force is discharged through the through hole 300, and the remaining part of the airflow force deforms and extrudes the second exterior part 120, thereby generating a greater overlapping force between the lip structure and the second exterior part 120. The greater overlapping force can ensure that the lip structure and the second exterior part 120 remain in contact, so that the trim strip 220 will not produce noise due to the airflow hitting the second exterior part 120.

[0069] In the second possible implementation, please refer to Figure 6 , Figure 6is a structure schematic view of a connection between the edge covering strip assembly 200 and the vehicle body 100. In this embodiment, the same content as the first embodiment will not be described again, and the difference from the first embodiment is that the first connection section 221a forms a main body structure alone, and the second connection section 221b and the contact section 222 jointly form a lip structure. The hardness of the first connection section 221a and the hardness of the second connection section 221b are different. The hardness of the second connection section 221b and the hardness of the contact section 222 are the same. Specifically, the hardness of the first connection section 221a is in the range of HA70°-90°, and the hardness of the contact section 222 and the second connection section 221b is in the range of HA50°-60°.

[0070] The curvature center of the first connection section 221a and the curvature center of the second connection section 221b are on the same side of the edge covering strip 220. In the side view perpendicular to the extension direction of the edge covering strip 220, the first connection section 221a and the second connection section 221b are smoothly connected to form a curved arc structure.

[0071] In this embodiment, the second connection section 221b and the contact section 222 are connected by bending, that is, the lip structure is a bent strip connected to one side of the main body structure. The included angle b between the second connection section 221b and the contact section 222 is an acute angle, and the included angle range can be between 30°-60° (including the end point values 30° and 60°).

[0072] It can be understood that the main body structure and the contact section 222 are connected by the second connection section 221b, which can better utilize the lip structure with smaller hardness, so that the edge covering strip 220 as a whole can have better elastic deformation capability. In actual use, the relative position and spacing between the edge of the first exterior part 210 of the vehicle 1000 and the second exterior part 120 are different, and the larger elastic deformation of the edge covering strip 220 can make it applicable to a variety of vehicles 1000, thereby improving the applicability of the edge covering strip 220.

[0073] The curvature center of the first connection section 221a and the curvature center of the second connection section 221b are on the same side of the edge covering strip 220, which can make the driving airflow better flow to the position of the through hole 300, so that the edge covering strip 220 will not be pressed down due to excessive wind resistance, and the situation that the edge covering strip 220 hits the second exterior part 120 due to poor contact between the edge covering strip 220 and the second exterior part 120 is avoided. In summary, the curvature center of the first connection section 221a and the curvature center of the second connection section 221b can be set differently according to the different materials of the first connection section 221a and the second connection section 221b to adapt to more use cases.

[0074] In the third possible embodiment, please refer to Figure 7 , Figure 7is another structure schematic view of the connection between the edge covering strip assembly 200 and the vehicle body 100 provided by the embodiment of the present application. In the embodiment, the same content as in the first embodiment will not be described again. Different from the first embodiment, the contact section 222 is connected to the first surface of the second end of the connecting section 221 and has a spacing with the edge end surface of the second end. That is, the lip structure is connected to the middle part of the main body structure. It can be understood that arranging the lip structure in the middle part of the main body structure can flexibly adjust the distance between the lip structure and the first outer trim 210, that is, the embodiment is applicable to the case that the edge of the second outer trim 120 is close to the edge of the first outer trim 210.

[0075] In the above three embodiments, the main body structure and the lip structure can be connected by an extrusion molding method or by an integral injection molding method. It can be understood that the structure of the integrally formed edge covering strip 220 is more stable and is not easy to be damaged.

[0076] Please refer to Figure 8 , Figure 8 is a flow direction schematic view of the driving airflow 1 at the edge covering strip 220 of the vehicle 1000 provided by the embodiment of the present application. When the vehicle 1000 is driving, the driving airflow 1 is generated, and the driving airflow 1 is divided into three parts on the side of the edge covering strip 220 facing outward, which are respectively a first sub-flow 2, a second sub-flow 3 and a third sub-flow 4. The first sub-flow 2 passes through the through hole 300 to pass through the edge covering strip 220, thereby reducing the wind resistance of the edge covering strip 220. The second sub-flow 3 acts on the connecting section 221 of the edge covering strip 220, thereby pressing the connecting section 221 of the edge covering strip 220 downward to the vehicle body 100. The third sub-flow 4 acts on the surface of the contact section 222 facing the connecting section 221, and the third sub-flow 4 presses the contact section 222 to the second outer trim 120, so that the contact section 222 and the second outer trim 120 are tightly lapped. After the third sub-flow 4 acts on the contact section 222, the flow direction changes, bounces to the connecting section 221, and can pass through the edge covering strip 220 through the through hole 300.

[0077] The embodiments of the present application are described in detail above, and the specific examples are applied to the principle and implementation mode of the present application. The above embodiment description is only used to help understand the method and core idea of the present application; at the same time, for the general technical personnel in the art, according to the idea of the present application, the specific implementation mode and application range will be changed; in conclusion, the content of the specification should not be understood as the limitation of the present application.
