[0002] In traditional gasoline-powered vehicles, a relatively large gap is designed between the windshield and the trunk lid to facilitate engine cooling within the trunk lid and to prevent rainwater intrusion. However, with the development of electric vehicles, the engine is no longer located in the trunk lid, and the empty space below is used for storage. This gap not only wastes space but also increases wind resistance and wind noise during vehicle operation. Therefore, there is an urgent need for a sash strip structure to optimize the connection between the windshield and the trunk lid, reducing the gap and thus minimizing wind resistance and wind noise during vehicle operation.

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] In traditional gasoline-powered vehicles, a relatively large assembly gap is left between the windshield and the front hood. This design is primarily based on two considerations: firstly, to provide necessary heat dissipation space for the engine compartment, and secondly, to facilitate the installation of waterproof structures to prevent rainwater from seeping into the engine area. However, with the rapid development of new energy vehicle technology, especially the widespread adoption of electric vehicles, the front compartment structure has changed. The traditional engine has been moved out, and this area has been redesigned as storage space. This structural evolution has brought new problems: firstly, the utilization rate of the front compartment space has decreased; secondly, significant air turbulence is generated when the vehicle is traveling at high speeds, leading to an increase in the drag coefficient and wind noise, thereby affecting the overall performance and ride comfort of the vehicle.

[0049] To address the aforementioned issues, this application provides an edge trim assembly and a vehicle. By incorporating a lip structure, a main structure, and a support structure, the lip structure undergoes elastic deformation when the front cover is pressed down, and the support structure transmits the pressure to the main structure, ensuring a tight fit against the edge of the windshield. This optimizes the connection between the windshield and the front cover, reduces the gap between them, decreases wind resistance during vehicle operation, and consequently reduces wind noise, thereby enhancing the driving experience.

[0050] The following will combine Figures 1 to 5 The specific structure of the vehicle provided in the embodiments of this application will be described.

[0051] Reference Figure 1 and Figure 2 As shown in the illustration, this application provides a vehicle 200, which can be an electric vehicle, a traditional fuel vehicle, or a commercial vehicle. This embodiment does not limit the scope of the vehicle.

[0052] Among them, reference Figure 3 and Figure 4 and combined Figure 7 As shown, the vehicle 200 includes a body sheet metal 210, a hinged component, and glass. In this embodiment, the hinged component can be a front hood 220, and the glass can be a windshield 230. This embodiment does not limit the specific components.

[0053] The windshield 230 is mounted on the body sheet metal 210 and is positioned by the limiting boss 1222 of the edge trim assembly 100. Figure 7 (As shown) Separated from the body sheet 210, the front cover 220 is located on the side of the windshield 230 away from the body sheet 210.

[0054] It should be noted that the windshield 230 and the body sheet 210 are not in rigid contact, but are separated by a limiting boss 1222. This helps to ensure that a certain distance is maintained between the windshield 230 and the body sheet 210, thereby preventing direct contact between the windshield 230 and the body sheet 210, reducing vibration transmission, and avoiding the risk of the windshield 230 being compressed due to assembly errors when the front cover 220 is closed, thus improving the stability and sealing of the windshield 230 installation.

[0055] Since there is a gap between the front hood 220 and the windshield 230, in order to optimize the connection between the front hood 220 and the windshield 230 and reduce the gap between them, this embodiment of the application refers to... Figures 3 to 5 As shown, it also includes a edging strip assembly 100, which connects the front box cover 220 and the windshield 230, thereby dynamically adapting to the relative displacement between the two.

[0056] Understandably, "dynamically adapting to relative displacement" means that during the opening or closing of the front cover 220, the edge strip assembly 100 adapts to the gap change through elastic deformation, thereby maintaining a continuous seal. This helps ensure that there is no water leakage between the front cover 220 and the windshield 230, reduces wind resistance during driving, lowers wind noise during driving, and improves the driving experience.

[0057] The following will continue to combine Figures 3 to 9 The specific structure of the edge banding component provided in the embodiments of this application will be described.

[0058] Reference Figures 3 to 5 As shown, this application embodiment provides a edging strip assembly 100, including a lip structure 110, a main body structure 120, and a support structure 130. The lip structure 110 abuts against the bottom of the front hood 220 and is configured to receive downward pressure from the front hood 220 and undergo elastic deformation. The main body structure 120 is fixedly connected to the edge of the windshield 230, and the support structure 130 connects the lip structure 110 and the main body structure 120.

[0059] It should be noted that, referring to Figure 3As shown, during assembly, the main structure 120 of the edge trim assembly 100 provided in this embodiment is fixedly connected to the edge of the windshield 230, and the front hood 220 is connected above the lip structure 110, causing the lip structure 110 to deform. The support structure 130 serves as an intermediate connector, linking the lip structure 110 and the main structure 120 together. When subjected to external force, the lip structure 110 undergoes elastic deformation, and its deformation force is transmitted to the main structure 120 through the support structure 130, causing the main structure 120 to move towards the edge of the windshield 230 to seal the gap between the front hood 220 and the windshield 230.

[0060] For example, the main structure 120 can be attached to the edge of the windshield 230 by adhesive bonding; or it can be attached to the windshield 230 by injection molding. In this embodiment, the adhesive bonding method is mainly used as an example for explanation.

[0061] In this embodiment, refer to Figure 4 As shown, the height of the lip structure 110 is similar to the edge height of the front hood 220, which helps to reduce the impact of airflow during driving. In addition, the lip structure 110 is connected and assembled with the front hood 220. The force generated by the front hood 220 on the lip structure 110 can cause the root of the lip structure 110 to be lifted upward, thereby better connecting with the edge of the windshield 230.

[0062] In this embodiment, refer to Figure 4 As shown, the edge where the front hood 220 connects to the lip structure 110 is higher than the edge of the windshield 230. This reduces the force of airflow on the lip structure 110, helping to reduce excessive force on the lip structure 110 and thus reducing vibrations or wind noise. For example, the distance between the edge where the front hood 220 connects to the lip structure 110 and the edge of the windshield 230 can be... Figure 4 As shown in d. The specific value of d is not limited; it can be assembled according to actual needs.

[0063] It should be noted that the elastic deformation force of the lip structure 110 in this embodiment can come from the following two sources: for example, the direct pressure applied to the lip structure 110 when the front cover plate 220 is pressed down; or, the wind pressure generated by the airflow on the lip structure 110 during vehicle 200 operation. This embodiment does not limit this. It should be noted that any force that can cause effective elastic deformation of the lip structure 110 can achieve the sealing effect of this application. This design allows the edge strip assembly 100 to meet both static sealing requirements and dynamic sealing requirements during vehicle 200 operation.

[0064] Furthermore, this embodiment does not limit the material of the edge banding assembly 100. For example, it can be TPE, EPDM, or PVC. TPE (Thermoplastic Elastomer) possesses the elasticity of rubber and the processability of plastic, with good compression set recovery; EPDM (Ethylene Propylene Diene Monomer) offers stable sealing performance; PVC (Polyvinyl Chloride) is inexpensive and suitable for short-term use. This embodiment does not limit this aspect.

[0065] The edge trim assembly 100 provided in this embodiment, by setting a lip structure 110, a main structure 120 and a support structure, allows the lip structure 110 to generate elastic deformation when the front cover plate 220 is pressed down, and the support structure 130 to transmit the pressure to the main structure 120, so that it fits tightly against the edge of the windshield 230, thereby optimizing the connection between the windshield 230 and the front cover plate 220, reducing the gap between the front cover plate 220 and the windshield 230, reducing wind resistance during vehicle 200 driving, thereby reducing wind noise during driving and improving the driving experience.

[0066] In one embodiment, reference Figures 3 to 5 As shown, one end of the support structure 130 is connected to the side of the lip structure 110 away from the front box cover 220, and the other end of the support structure 130 is connected to the side of the main structure 120 away from the windshield 230.

[0067] It should be noted that the design of the edge trim assembly 100 in this application addresses the problem of excessive gap between the front hood 220 and the windshield 230 caused by the edge trim protruding outwards in traditional solutions. In this application, one end of the edge trim assembly 100 extends away from the front hood 220, and the other end extends away from the windshield 230, allowing the edge trim assembly 100 to be fully accommodated between the front hood 220 and the windshield 230. This helps to further reduce the gap between the front hood 220 and the windshield 230, and also helps to increase the storage space of the front hood 220.

[0068] In one embodiment, reference Figures 3 to 5As shown, the support structure 130 may include a lip support arm 131 and a main support arm 132. One end of the lip support arm 131 is connected to the side of the lip structure 110 away from the front hood 220, and the other end of the lip support arm 131 extends from the lip structure 110 along the side away from the front hood 220. One end of the main support arm 132 is connected to the free end of the lip support arm 131, and the other end of the main support arm 132 is connected to the side of the main structure 120 away from the windshield 230. When the lip structure 110 is deformed under pressure, it causes the lip support arm 131 to displace, and the displacement is transmitted to the main structure 120 through the main support arm 132.

[0069] In this embodiment, by providing a lip support arm 131, the connection between the lip structure 110 and the front cover plate 220 can be enhanced. By providing a main support arm 132 located at the edge of the windshield 230, the assembly effect of the main support arm 132 on the main structure 120 is enhanced.

[0070] The lip support arm 131 and the main support arm 132 can be integrated as one piece; or they can be two independent structures. In this embodiment, the lip support arm 131 and the main support arm 132 are mainly used as two independent structures for illustration, which facilitates the adjustment of the force of the two support arm structures.

[0071] The lip support arm 131 and the main support arm 132 can be connected or separate. In this embodiment, the connection between the lip support arm 131 and the main support arm 132 is used as an example for illustration, which facilitates the transmission of structural forces between the two support arms. For example, the lip support arm 131 and the main support arm 132 can be connected by adhesive. This embodiment does not limit this method.

[0072] The lip support arm 131 and the main support arm 132 can be made of different materials. For example, the lip support arm 131 can be made of flexible TPE material, while the main support arm 132 can be made of rigid PP material, thus facilitating the matching of local stiffness differences. For example, the boundary between the soft and hard materials of the lip support arm 131 and the main support arm 132 can be referenced... Figure 6 and Figure 7 As shown by the dashed line.

[0073] Therefore, by setting up a split lip support arm 131 and a main support arm 132, the lip support arm 131 converts the vertical downward pressure of the lip structure 110 into a lateral component force, and the main support arm 132 then guides the force to the main structure 120, forming a force transmission path, which helps to improve the clamping force of the main structure 120 on the edge of the glass.

[0074] In one embodiment, reference Figure 4 As shown, the extension direction of the lip support arm 131 forms an angle A with the extension direction of the main support arm 132, wherein the angle A satisfies the condition: 90° < A < 180°. The extension direction of the main support arm 132 is the same as the extension direction of the windshield 230, both of which can extend horizontally, while the lip support arm 131 extends downward at an angle.

[0075] For example, the angle A between the extending direction of the lip support arm 131 and the extending direction of the main support arm 132 can be 100°, 110°, 120°, 150° or any value between 90° and 180°. This embodiment does not limit this, and it can be set according to actual needs.

[0076] If the included angle A is less than 90°, then A is an acute angle, and the main support arm 132 is prone to tilting upwards. This results in an obstructed force transmission path and insufficient sealing pressure when the front cover 220 is pressed down. Stress concentration is also likely to occur at the root of the support arm, which may lead to breakage after long-term use. If the included angle A is greater than 180°, the lip support arm 131 bends in the opposite direction, causing the main structure 120 to be pushed away from the windshield 230, completely losing its sealing function.

[0077] Therefore, by setting the included angle A within the range of 90-180°, it helps to avoid stress concentration or functional failure caused by acute angles or reverse angles, and maximizes the conversion rate of vertical pressure into horizontal sealing force. At the same time, the obtuse angle design is beneficial to the force transmission of the support arm and allows the main support arm 132 to apply greater pressure to the main structure 120.

[0078] Specifically, in this embodiment, referring to Figure 5 As shown, the vertical downward pressure of the front cover plate 220 on the lip structure 110 is F1, which is a vertically downward force. The elastic reaction force of the lip structure 110 on the front cover plate 220 is F2, which is the rebound force generated after being deformed by pressure. It is the opposite of F1 and is a vertically upward force.

[0079] The force F3 exerted by the lip support arm 131 and the main support arm 132 on the main structure 120 causes the main structure 120 to move towards the edge of the glass. F3 is a horizontal sealing force to the right, consistent with the direction of movement of the main structure 120.

[0080] In one embodiment, reference Figure 8 and Figure 9 As shown, the extension direction of the support structure 130 and the extension direction of the windshield 230 have an angle B, wherein the angle B satisfies the condition: 90° < A < 180°.

[0081] The difference between this embodiment and the above embodiments is that: (Refer to...) Figure 8 and Figure 9 As shown, in this embodiment, the lip support arm 131 and the main support arm 132 are an integral structure, thus limiting the included angle between the support structure 130 and the windshield 230. The number of support structures 130 is not limited; there can be one or more support structures 130. In this embodiment, a single support structure 130 is used as an example for explanation.

[0082] Specifically, in this embodiment, referring to Figure 8 As shown, when there is only one support structure 130, the total downward pressure of the front cover plate 220 on the lip structure 110 is F1, and the elastic reaction force of the lip structure 110 on the front cover plate 220 is F2, which is the rebound force generated after being deformed by pressure. The component forces of the front cover plate 220 on the edge strip assembly 100 are F11 and F12.

[0083] Reference Figure 9 As shown, when there are two support structures 130, the total downward pressure of the front cover plate 220 on the lip structure 110 is F11 and F12 respectively, and the elastic reaction force of the lip structure 110 on the front cover plate 220 is F2, which is the rebound force generated after being deformed by pressure.

[0084] For example, the angle B between the extending direction of the support structure 130 and the extending direction of the windshield 230 can be 100°, 110°, 120°, 150° or any value between 90° and 180°. This embodiment does not limit this, and it can be set according to actual needs.

[0085] If the included angle B is less than 90°, the support structure 130 folds upwards, and when the front cover 220 is pressed down, the lip structure 110 cannot achieve effective compression, making the seal prone to failure. Furthermore, the glass edge is subjected to peeling stress, which may cause the adhesive layer to crack. If the included angle B is greater than 180°, the support structure 130 bends towards the body sheet metal 210, causing the main structure 120 to be easily pulled away from the glass edge, resulting in poor sealing performance. Therefore, by setting the included angle B within the range of 90-180°, the inclined support arm helps to disperse the lip deformation, keeping the contact pressure at the glass edge within the normal range.

[0086] In one embodiment, the hardness of the lip structure 110 is less than the hardness of the main structure 120; wherein, the hardness of the lip structure 110 is a, and a can satisfy the condition: a≤70Ha; the hardness of the main structure 120 is b, and b can satisfy the condition: 70Ha≤b≤90Ha.

[0087] Among them, hardness can refer to Shore hardness, the unit of which is Ha.

[0088] For example, the hardness 'a' of the lip structure 110 can be any value of 50Ha, 60Ha, 70Ha, or less than 50Ha. It should be noted that the hardness 'a' of the lip structure 110 cannot be infinitely small, to avoid it being too soft and unable to provide sufficient resilience F2. For example, the hardness 'b' of the main structure 120 can be any value of 70Ha, 75Ha, 80Ha, 85Ha, 90Ha, or between 70Ha and 80Ha. This embodiment does not limit this.

[0089] For example, the lip structure 110 can be made of soft TPE or EPDM, whose lower hardness ensures easy deformation under pressure, tightly conforming to the bottom contour of the front cover 220. The main structure 120 can be made of a harder material, such as rigid TPV (thermoplastic vulcanizate), which helps provide rigid support, prevents bending and deformation of the structure during force transmission, and can efficiently convert deformation force into horizontal sealing force.

[0090] Furthermore, the main support arm 132 and the lip support arm 131 can be made of materials with the same hardness or materials with different hardnesses. In this embodiment, the main support arm 132 and the lip support arm 131 are made of materials with different hardnesses, which helps to better adjust the force of different support arm structures, thereby obtaining a better assembly effect.

[0091] In one embodiment, reference Figure 6 and Figure 7 As shown, the connection surface between the lip structure 110 and the front cover plate 220 can be provided with a wear-resistant coating 111. The coating can be applied by spraying to reduce the connection friction between the lip structure 110 and the front cover plate 220, thereby reducing the wear caused by friction on the surface coating of the lip structure 110 and the front cover plate 220.

[0092] For example, the wear-resistant coating 111 can be a polyurethane coating, a PETT coating, or a ceramic-based coating, etc. This embodiment does not limit this, and it can be set according to actual needs.

[0093] In some embodiments, the connection surface between the lip structure 110 and the front cover plate 220 may be provided with a flocking layer. That is, flocking the connection surface can also help reduce the connection friction between the lip structure 110 and the front cover plate 220, thereby reducing the wear of the surface coating of the lip structure 110 and the front cover plate 220 caused by friction.

[0094] In one embodiment, the thickness of the wear-resistant coating 111 can range from 0.05 mm to 2 mm. For example, the thickness of the wear-resistant coating 111 can be 0.05 mm, 0.06 mm, 0.07 mm, 0.1 mm, 1.0 mm, 1.5 mm, 1.8 mm, 2 mm, or any value between 0.55 mm and 2 mm. This embodiment does not limit this; the specific thickness can be set according to actual needs.

[0095] If the thickness of the wear-resistant coating 111 is less than 0.05 mm, a continuous protective layer cannot be formed, and there is a risk of local exposure leading to wear on the joint surface; if the thickness of the wear-resistant coating 111 is greater than 2 mm, the accumulation of internal stress in the coating is prone to cracking.

[0096] Therefore, by setting the thickness of the wear-resistant coating 111 to be between 0.05 mm and 2 mm, while ensuring the flexible sealing of the lip structure 110, friction and wear are significantly reduced, and the service life of the front cover plate 220 and the edge strip assembly 100 is extended.

[0097] In some embodiments, reference is made to Figures 3 to 5 As shown, the connection surface between the lip structure 110 and the front cover plate 220 can be an arc surface. On the one hand, the arc surface contact can significantly increase the actual contact area, making the sealing pressure distribution more uniform and reducing local stress concentration; on the other hand, the arc contour produces a gradual deformation when the front cover plate 220 is pressed down, effectively reducing the initial impact force.

[0098] In one embodiment, reference Figure 6 and Figure 7 As shown, the main structure 120 may include a first main segment 121 and a second main segment 122 connected to each other, and the windshield 230 includes a first edge segment 231 and a second edge segment 232 that are critical to each other and set at an angle; the first main segment 121 is connected to the support structure 130 and fits and wraps around the first edge segment 231, and the second main segment 122 extends to the second edge segment 232 and fits and wraps around at least a portion of the second edge segment 232.

[0099] Understandably, the first main body segment 121 fully covers the first edge segment 231 to block moisture from entering the windshield 230 to the greatest extent; the second main body segment 122 partially covers the second edge segment 232 to allow the windshield 230 to expand and contract with temperature, thus avoiding stress cracks caused by hard contact.

[0100] In one embodiment, reference Figure 7As shown, the second main body segment 122 has a main body bonding groove 1221, the opening of which faces the second edge segment 232. Main body adhesive 140 can be provided in the main body bonding groove 1221, and the second edge segment 232 is connected to the second main body segment 122 through the main body adhesive 140. This effectively improves the adhesion between the windshield 230 and the main body structure 120, enhancing the bonding strength.

[0101] In one embodiment, reference Figure 6 and Figure 7 As shown, a limiting boss 1222 can extend from the side of the second main body segment 122 away from the second edge segment 232. The limiting boss 1222 is configured to separate the windshield 230 from the body sheet metal 210.

[0102] This ensures a certain distance between the windshield 230 and the body sheet 210, which helps prevent direct contact between the windshield 230 and the body sheet 210, thereby reducing vibration transmission and avoiding the risk of the windshield 230 being compressed due to assembly errors when the front cover 220 is closed, thus ensuring the stability and sealing of the windshield 230 installation.

[0103] In some embodiments, because the edging strip is made of plastic, it is prone to shrinkage or expansion due to temperature changes, which can reduce its adhesive strength and make it easy to fall off the windshield 230. Therefore, the main structure 120 may include an insert to limit its thermal expansion and contraction, exemplarily referring to... Figure 7 As shown, it can be a shrink-proof copper core 123.

[0104] This embodiment provides a edging strip assembly and a vehicle. The assembly includes a lip structure, a main structure, and a support structure. When the front cover is pressed down, the lip structure undergoes elastic deformation, and the support structure transmits the pressure to the main structure, making it fit tightly against the edge of the windshield. This optimizes the connection between the windshield and the front cover, reduces the gap between the front cover and the windshield, reduces wind resistance during vehicle operation, and thus reduces wind noise and improves the driving experience.

[0105] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0106] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
