Examples of the embodiments are shown in the drawings, where like or similar reference numerals denote like or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0032] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present utility model.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0033] The sealing strip 1 according to the embodiment of the first aspect of the present utility model will be described below with reference to the drawings.

[0034] As Figures 1 to 5 shown, the sealing strip 1 according to the embodiment of the first aspect of the present utility model includes: a sealing strip body 11, the sealing strip body 11 includes a main body portion 111 and a plurality of sealing lips protruding from the main body portion 111. The plurality of sealing lips include a first sealing lip 112 and an inverted buckle lip 113 provided on the same side of the main body portion 111. The inverted buckle lip 113 is located inside the first sealing lip 112, and the height of the inverted buckle lip 113 protruding from the outer surface of the main body portion 111 is greater than the height of the first sealing lip 112 protruding from the outer surface of the main body portion 111. It should be noted that the outer surface of the main body portion 111 herein refers to the surface of the main body portion 111 where the first sealing lip 112 and the inverted buckle lip 113 are provided.

[0035] Wherein, the sealing strip 1 can be inserted into the gap of the component to be sealed, so as to form an interference fit with the gap of the component to be sealed, and further form a physical partition on both the inner and outer sides of the sealing strip 1 to prevent water and sundries such as dust and stones from entering the gap and accumulating. It should be noted that in the description herein, "inner side" refers to the side close to the internal space of the component to be sealed, and "outer side" refers to the side far from the internal space of the component to be sealed.

[0036] That is to say, the sealing strip body 11 can interfere with the gap of the component to be sealed through the first sealing lip 112. The first sealing lip 112 is relatively soft and easy to deform, so that the resistance between the sealing strip 1 and the gap of the component to be sealed can be reduced during the insertion process, and the first sealing lip 112 can better adapt to gaps of different shapes through deformation. At the same time, since the height of the undercut lip 113 is greater than the height of the first sealing lip 112 and is located on the inner side of the first sealing lip 112, while ensuring the sealing effect of the first sealing lip 112, at least part of the undercut lip 113, such as the free end part, can extend to the inner side of the component to be sealed and be stacked with the component to be sealed in the inner and outer directions, so that the undercut lip 113 can be blocked from moving outwards through the inner side of the component to be sealed.

[0037] Thus, the inner side of the component to be sealed faces the undercut lip 113 to block the outward movement of the sealing strip 1 relative to the gap, thereby preventing the sealing strip 1 from coming out of the gap, which helps to improve the installation firmness of the sealing strip 1. In addition, the first sealing lip 112 and the undercut lip 113 are located on the same side of the main body 111, so that at least two sealing positions can be formed by the first sealing lip 112 and the undercut lip 113, which helps to improve the sealing effect of the sealing strip 1.

[0038] According to the sealing strip 1 of the first aspect of the present invention, at least a portion of the undercut lip 113 can extend to the inner side of the component to be sealed and be stacked with the component to be sealed in the inner and outer directions. The inner side of the component to be sealed is limited by the undercut lip 113, which can better limit the outward movement of the sealing strip 1 relative to the gap of the component to be sealed, thereby preventing the sealing strip 1 from falling out of the gap, which is beneficial to improving the installation firmness of the sealing strip 1.

[0039] According to some embodiments of the utility model, the sealing strip 1 also includes a sealing strip skeleton 12 arranged in the sealing strip body 11, the sealing strip skeleton 12 includes a spring structure 121, the spring structure 121 includes a supporting portion 1211 and a spring 1212, a first angle is formed between the supporting portion 1211 and the spring 1212, the supporting portion 1211 is arranged in the main body 111, one end of the spring 1212 is connected to the supporting portion 1211, and the other end of the spring 1212 extends to the undercut lip 113.

[0040] Among them, a first included angle is formed between the supporting portion 1211 and the elastic piece 1212, so that the elastic piece structure 121 has good elastic restoring force to maintain the relative position between the supporting portion 1211 and the elastic piece 1212. The elastic piece structure 121 can better maintain the shape of the reverse buckle lip 113 through the part of the elastic piece 1212 located inside the reverse buckle lip 113, so that the reverse buckle lip 113 is kept in a state of interference contact with the inner side surface of the component to be sealed. That is, when it is necessary to remove the sealing strip 1, it is necessary to overcome the elastic force of the elastic piece structure 121. Thus, the risk of the sealing strip 1 coming out of the gap of the component to be sealed can be better reduced through the elastic piece structure 121, which is beneficial to improving the firmness of the sealing strip 1 installed in the gap.

[0041] In some embodiments, the supporting portion 1211 is substantially perpendicular to the thickness direction of the main body portion 111. One end of the elastic piece 1212 is connected to the inner end of the supporting portion 1211, and the other end of the elastic piece 1212 extends into the reverse buckle lip 113. Moreover, the end of the elastic piece 1212 far from the supporting portion 1211 extends to the end of the free end of the reverse buckle lip 113, so that the elastic piece 1212 can better cover the reverse buckle lip 113 to enhance the strength of the elastic piece 1212 to maintain the shape of the reverse buckle lip 113.

[0042] In some embodiments, the sealing strip body 11 is a flexible part, and the flexible part is relatively soft and easy to deform, so that the sealing strip body 11 can better interfere with the component to be sealed through deformation without causing damage. In a specific example, the sealing strip body 11 is EPDM (Ethylene Propylene Diene Monomer), so that the sealing strip body 11 has good aging resistance, which is beneficial to improving the service life of the sealing strip 1. In addition, the sealing strip skeleton 12 is a metal part, and the metal part is relatively hard and not easy to deform, so that the structural stability of the sealing strip skeleton 12 can be improved. In a specific example, the sealing strip body 11 is SUS301 stainless steel (austenitic stainless steel), which has good fatigue resistance and toughness and is light in weight.

[0043] In some embodiments, the sealing strip 1 is formed by injection molding the sealing strip body 11 outside the sealing strip skeleton 12. That is to say, the sealing strip body 11 wraps the sealing strip skeleton 12 through injection molding, so as to facilitate the arrangement of the sealing strip skeleton 12 inside the sealing strip body 11. At the same time, by adding the sealing strip skeleton 12 into the sealing strip body 11, the sealing strip 1 can be more firmly installed in the gap of the component to be sealed.

[0044] In some embodiments, the sealing strip body 11 is an integrally formed part. Thus, the integrally formed structure can not only ensure the structural and performance stability of the sealing strip body 11, but also is convenient for molding, simple in manufacturing, and eliminates the fittings and connection processes used for connecting multiple parts of the sealing strip body 11. The production cost is low, the assembly efficiency of the sealing strip body 11 is greatly improved, and the connection reliability of the sealing strip body 11 is ensured. Moreover, the overall strength and stability of the integrally formed structure are relatively high, and the service life is longer.

[0045] According to some embodiments of the present invention, the first included angle is an acute angle. That is to say, in the direction from the inside to the outside, the elastic piece 1212 extends obliquely away from the first side surface 1111. Therefore, when installing the sealing strip 1, the force required for the elastic piece 1212 to deform towards the support portion 1211 is smaller, so that the force required for installing the sealing strip 1 can be reduced. When pulling out the sealing strip 1, the force required for the elastic piece 1212 to deform away from the support portion 1211 is larger, thus facilitating the installation of the sealing strip 1 and improving the firmness of the sealing strip 1 after installation.

[0046] According to some embodiments of the present invention, the first included angle is not greater than 45°. That is to say, the included angle between the support portion 1211 and the elastic piece 1212 is less than or equal to 45°. It can be understood that the smaller the included angle between the support portion 1211 and the elastic piece 1212, the greater the force required to increase the included angle between the support portion 1211 and the elastic piece 1212. Therefore, setting the included angle between the support portion 1211 and the elastic piece 1212 to be not greater than 45° can increase the force required to increase the included angle between the support portion 1211 and the elastic piece 1212, thereby further increasing the elastic force that needs to be overcome when pulling out the sealing strip 1, so that the sealing strip 1 can be firmly installed in the gap of the component to be sealed. The included angle between the support portion 1211 and the elastic piece 1212 can be 25°, 28°, 30°, 33°, 35°, 38°, 40°, 45°, etc., and no specific limitation is made here.

[0047] According to some embodiments of the present invention, a through hole 1213 is provided at the connection position between the support portion 1211 and the elastic piece 1212. Therefore, through the through hole 1213, the structural strength of the connection position between the support portion 1211 and the elastic piece 1212 can be weakened, so that the external force required for the included angle between the support portion 1211 and the elastic piece 1212 to deform can be reduced, and thus it can be more labor-saving when inserting the sealing strip 1 to reduce the installation difficulty of the sealing strip 1.

[0048] According to some embodiments of the present invention, the sealing strip skeleton 12 further includes a connecting portion 122, the connecting portion 122 extending along the length direction of the sealing strip body 11, and a plurality of spring structures 121 arranged at intervals on the connecting portion 122 along the length direction of the sealing strip body 11. That is, the connecting portion 122 can connect the plurality of spring structures 121 in the sealing strip body 11 into a whole, thereby reducing the number of parts of the sealing strip 1, and in the production process of the sealing strip 1, the sealing strip skeleton 12 formed as an integral structure is easy to connect with the sealing strip body 11, such as when the sealing strip body 11 is injection molded on the sealing strip skeleton 12, the sealing strip skeleton 12 formed as an integral structure is easy to fix, which is conducive to reducing the difficulty of manufacturing the sealing strip 1. At the same time, in the length direction of the sealing strip body 11, by arranging a plurality of spring sheet structures 121 at intervals on the connecting portion 122, the plurality of spring sheet structures 121 can provide supporting force for the undercut lip 113 at multiple positions in the length direction of the sealing strip body 11, so that the undercut lip 113 can be more stably maintained in a position of interfering contact with the inner side surface of the component to be sealed, thereby increasing the force required to pull the sealing strip 1 out of the gap of the component to be sealed, thereby improving the firmness of the sealing strip 1 after installation.

[0049] In some embodiments, the spring sheet structures 121 are arranged at equal intervals. Therefore, the spring sheet structures 121 can evenly provide elastic support force for multiple positions of the undercut lip 113 in the length direction of the sealing strip body 11, so that any area of ​​the entire sealing strip 1 in the length direction is not easily pulled out of the gap, thereby improving the firmness of the sealing strip 1 after installation.

[0050] According to some embodiments of the utility model, in the direction from inside to outside, the sealing lip extends obliquely in the direction away from the main body 111. Therefore, when installing the sealing strip 1, the force required for the first sealing lip 112 and the undercut lip 113 to deform in the direction close to the main body 111 is small, thereby reducing the force required for installing the sealing strip 1. When pulling out the sealing strip 1, the force required for the first sealing lip 112 and the undercut lip 113 to deform in the direction away from the main body 111 is large, thereby reducing the force required for inserting the sealing strip 1 and increasing the force required for pulling out the sealing strip 1, thereby facilitating the installation of the sealing strip 1 and improving the firmness of the sealing strip 1 after installation.

[0051] According to some embodiments of the utility model, the two opposite sides of the main body 111 in the thickness direction are respectively the first side 1111 and the second side 1112, and the plurality of sealing lips further include a second sealing lip 114, the second sealing lip 114 is arranged on the second side 1112, and the first sealing lip 112 is arranged on the first side 1111. In other words, the main body 111 is provided with sealing lips on two opposite sides in the thickness direction. Thus, the contact position between the sealing strip 1 and the gap between the component to be sealed can be increased, which is conducive to improving the sealing effect of the sealing strip 1.

[0052] In some embodiments, the first sealing lip 112 and the second sealing lip 114 are provided with a plurality of them arranged at intervals along the inner and outer directions. Therefore, the interference contact position between the sealing strip body 11 and the component to be sealed can be increased by the plurality of first sealing lips 112 and second sealing lips 114, so that the sealing position between the sealing strip 1 and the component to be sealed can be increased, which is beneficial to improving the sealing effect of the sealing strip 1. In addition, the force required to pull out the sealing strip 1 can be increased, thereby improving the firmness of the sealing strip 1 after installation.

[0053] In a specific example, the number of the second sealing lips 114 is the same as the sum of the number of the first sealing lips 112 and the undercut lips 113, so as to ensure that the sealing strip 1 can form the same number of sealing positions on the opposite sides of the main body 111, so as to improve the uniform sealing of the sealing strip 1. For example, there is one first sealing lip 112, one undercut lip 113, and two second sealing lips 114, so that at least two sealing positions can be formed on the opposite sides of the main body 111, so as to improve the sealing effect.

[0054] According to some embodiments of the utility model, the sealing strip body 11 also includes a covering portion 115 arranged on the main body 111 and located outside the sealing lip. In the thickness direction of the main body 111, the height of the covering portion 115 protruding from the first side surface 1111 is greater than the height of the first sealing lip 112 protruding from the first side surface 1111. That is to say, the undercut lip 113 and the covering portion 115 are respectively located on opposite sides of the first sealing lip 112, and by setting the height of the covering portion 115 protruding from the first side surface 1111 to be greater than the height of the first sealing lip 112 protruding from the first side surface 1111, the sealing effect of the first sealing lip 112 can be ensured while the free end portion of the covering portion 115 protruding from the first side surface 1111 can extend to the outside of the component to be sealed and be stacked with the component to be sealed in the inside-outside direction, so that the covering portion 115 can be blocked from moving inwards by the component to be sealed, thereby limiting the inward movement of the sealing strip 1 relative to the component to be sealed, and the cooperation between the undercut portion and the covering portion 115 can form a clamping and fixation of the component to be sealed, so as to improve the stability of the sealing strip 1 after installation.

[0055] In addition, one end of the covering portion 115 is on the same side of the main body portion 111 as the first sealing lip 112 and the reverse buckle lip 113, and the other end of the covering portion 115 is on the same side of the main body portion 111 as the second sealing lip 114. Thus, multiple sealing positions can be formed between the covering portion 115, the first sealing lip 112, the reverse buckle lip 113 and the component to be sealed, and multiple sealing positions can be formed between the covering portion 115, the second sealing lip 114 and the component to be sealed, which is beneficial to improving the sealing effect of the sealing strip 1.

[0056] In a specific example, in the thickness direction of the main body portion 111, one end of the covering portion 115 protrudes from the first side surface 1111 and the other end protrudes from the second side surface 1112. The part of the covering portion 115 protruding from the second side surface 1112 can jointly seal the gap on the side of the second side surface 1112 with the second sealing lip 114 to improve the sealing effect.

[0057] According to some embodiments of the present invention, the height of the covering portion 115 protruding from the first side surface 1111 is greater than the height of the reverse buckle lip 113 protruding from the first side surface 1111. Among them, the greater the height of the covering portion 115 protruding from the first side surface 1111, the larger the contact area between the covering portion 115 and the outer side surface of the component to be sealed, the larger the sealing area, and the higher the limiting effect. Thus, the sealing effect of the sealing strip 1 can be improved, and at the same time, the firmness of the sealing strip 1 after installation can be improved.

[0058] Next, the vehicle body structure 100 according to the second aspect embodiment of the present invention will be described with reference to the accompanying drawings.

[0059] The vehicle body structure 100 according to the second aspect embodiment of the present invention includes: a side wall frame 2, a windshield 3, and a sealing strip 1. The windshield 3 is adhesively connected to the side wall frame 2 in the thickness direction of the windshield 3. A relief gap 4 is defined between the windshield 3 and the side wall frame 2 on the outer peripheral side of the windshield 3. The sealing strip 1 is disposed in the relief gap 4. That is to say, the part of the side wall frame 2 opposite to the outer peripheral surface of the windshield 3 is spaced apart from the outer peripheral surface of the windshield 3. The relief gap 4 formed between the windshield 3 and the side wall frame 2 can preferably prevent contact between the windshield 3 and the side wall frame 2, thereby preventing extrusion damage to the windshield 3. Among them, the sealing strip 1 can form an interference fit with the relief gap 4.

[0060] Thus, the sealing strip 1 can better seal the avoidance gap 4 to form a physical partition on both sides of the sealing strip 1, so that the sealing strip 1 can prevent rainwater and debris such as dust, branches and stones from entering and accumulating in the avoidance gap 4. At the same time, after the sealing strip 1 is inserted into the avoidance gap 4 with the first side surface 1111 facing the windshield 3, the first sealing lip 112 can interfere with the outer peripheral surface of the windshield 3 to achieve sealing, and the undercut lip 113 can extend to the inner side of the windshield 3 and be stacked with the windshield 3 along the thickness direction of the windshield 3, so that the undercut lip 113 can be blocked from moving outward by the inner side of the windshield 3. Therefore, the inner side of the windshield 3 facing the undercut lip 113 can better limit the outward movement of the sealing strip 1 relative to the avoidance gap 4, so that the sealing strip 1 can be prevented from escaping from the avoidance gap 4, which is conducive to improving the installation firmness of the sealing strip 1. In addition, the air flow entering the avoidance gap 4 to generate air resistance can be avoided, which is beneficial to improving the aerodynamic performance of the vehicle body structure 100. By sealing the avoidance gap 4 with the sealing strip 1, the number of gaps on the vehicle body structure 100 can be reduced, thereby beautifying the appearance of the vehicle body structure 100.

[0061] According to the vehicle body structure 100 of the second aspect of the utility model, the inner side of the windshield 3 is limited by the undercut lip 113 to better limit the outward movement of the sealing strip 1 relative to the avoidance gap 4, thereby preventing the sealing strip 1 from escaping from the avoidance gap 4, which is beneficial to improving the installation firmness of the sealing strip 1.

[0062] According to some embodiments of the utility model, the first sealing lip 112 is in interference contact with the outer peripheral side surface of the windshield 3, and at least a portion of the undercut lip 113 abuts against the inner side surface of the windshield 3 along the thickness direction of the windshield 3. In other words, at least a portion of the undercut lip 113 is located on the inner side of the windshield 3 and abuts against the inner side surface of the windshield 3, so that the undercut lip 113 can be blocked from moving outward by the windshield 3, and the sealing position between the sealing strip 1 and the windshield 3 can be increased, so as to improve the sealing effect of the sealing strip 1 on the avoidance gap 4.

[0063] According to some embodiments of the present invention, the sealing strip 1 is detachably disposed in the avoidance gap 4. Therefore, when the sealing strip 1 is damaged, the user can remove the sealing strip 1 from the avoidance gap 4 and replace it with a new sealing strip 1, which helps to reduce the difficulty of replacing the sealing strip 1.

[0064] In some embodiments, the side frame 2 includes a peripheral structure 21 and a supporting structure 22. The peripheral structure 21 is located on the outer peripheral side of the windshield 3 and is separated from the windshield 3 to form an avoidance gap 4. One end of the supporting structure 22 is connected to the inner side of the peripheral structure 21 and is roughly parallel to the windshield 3. The supporting structure 22 is located on the inner side of the windshield 3 and is separated from the windshield 3. The gap between the supporting structure 22 and the windshield 3 is filled with glass glue 51. A blocking strip 52 is provided on the side of the glass glue 51 close to the avoidance gap 4. The blocking strip 52 is spaced apart from the glass glue 51. The end of the blocking strip 52 close to the avoidance gap 4 is spaced apart from the end of the windshield 3 close to the avoidance gap 4.

[0065] In some embodiments, the vehicle body structure 100 further includes a top cover outer panel 6, which is located on the top of the windshield 3 and is spaced apart from the windshield 3. A sealing strip 1 is provided in the gap between the top cover outer panel 6 and the windshield 3, and the sealing strip 1 is in interference contact with both the top cover outer panel 6 and the windshield 3, so that the gap between the top cover outer panel 6 and the windshield 3 can be well sealed by the sealing strip 1, and then a physical partition can be formed on both sides of the sealing strip 1 to prevent rainwater and debris such as dust, branches and stones from entering and accumulating in the gap. In addition, air resistance caused by airflow entering the gap can be avoided, which is beneficial to improving the aerodynamic performance of the vehicle. By sealing the gap with the sealing strip 1, the number of gaps on the vehicle can be reduced, thereby beautifying the appearance of the vehicle.
