It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0040] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other different manners from those described herein; obviously, the embodiments in the description are only some embodiments of the present application, not all embodiments.
[0041] The sealing structure and the vehicle will be described in detail below through specific embodiments:
[0042] Referring to Figures 1 to 5 It is shown that some embodiments of the present application provide a sealing structure suitable for being installed on an engine cover 2 of a vehicle, comprising a sealing body 1, the sealing body 1 is arranged along a front end edge of the engine cover 2, a plug-in part 11 is formed on the sealing body 1, a plug-in slot 111 with a slot opening towards the engine cover 2 is formed on the plug-in part 11, the plug-in slot 111 is plug-in matched with the front end edge of the engine cover 2, so as to install the sealing body 1 on the front end edge of the engine cover 2 through the slot opening of the plug-in slot 111.
[0043] Specifically, the plug-in slot 111 is arranged along the front end edge of the engine cover 2 to be plug-in matched with the front end edge of the engine cover 2 as a whole, so as to ensure the plug-in strength.
[0044] The sealing body 1 is further provided with a first sealing part 12 and a second sealing part 13, the first sealing part 12 is used for sealing cooperation with an engine cover 3 of the vehicle, and the second sealing part 13 is used for sealing cooperation with a vehicle lamp 4 and / or a bumper assembly of the vehicle.
[0045] In specific implementation, the sealing body 1 is arranged along the front end edge of the engine cover 2, the first sealing part 12 is sealingly matched with the engine cover 3, and the second sealing part 13 is sealingly matched with the vehicle lamp 4 and / or the bumper assembly, so that the sealing effect of the split joint of the engine cover 3 at the front end of the vehicle can be achieved, the wind from the split joint is avoided, and the whistling noise caused by the wind is avoided. The force when closing the engine cover 3 can be buffered, the sealing body 1 can be inserted and matched with the front end edge of the engine cover 2 through the insertion groove 111, so that the connection is stable, the problem of falling caused by the poor adhesion of the existing sealing strip is avoided, the product usability and the delicate appearance are improved, and the sealing structure is easy to disassemble and maintain. When the sealing structure is installed, the sealing body 1 can be directly inserted and installed at the front end of the engine cover 2, without the need to additionally set the buckle structure on the engine cover 3, the metal plate of the engine cover 3 is not damaged, the vehicle safety and pedestrian protection can be improved, and the safety regulations are met.
[0046] It should be noted that the sealing body 1 can be a sealing strip structure, which can be adapted to the shape of the front end edge of the engine cover 2. In this way, the sealing between the engine cover 3 and the vehicle lamp 4 and between the engine cover 3 and the bumper assembly can be achieved. That is, the sealing body 1 can abut the lower edge of the engine cover 3 and can abut the upper edge of the vehicle lamp 4 and / or the bumper assembly, so as to achieve the sealing of the split joint.
[0047] Specifically, the sealing body 1 can be adapted to the length of the upper edge of the vehicle lamp 4 to abut the upper edge of the vehicle lamp 4, can be adapted to the length of the upper edge of the bumper assembly to abut the upper edge of the bumper assembly, and can be adapted to the length of the upper edge of the vehicle lamp 4 and the upper edge of the bumper assembly as a whole, so that different sections of the sealing body 1 can abut the upper edge of the vehicle lamp 4 and the upper edge of the bumper assembly, respectively.
[0048] Referring to Figure 1 The sealing body 1 includes a horizontal section extending along the width direction of the vehicle body and vertical sections located at both ends of the horizontal section. In this way, the sealing body 1 can be adapted to the shape of the front end edge of the engine cover 2.
[0049] Referring to Figure 5 When the sealing body 1 is inserted into the engine cover 2, it can be supported on the top surface of the vehicle lamp 4 and / or the bumper assembly. The sealing body 1 abuts between the front edge of the vehicle lamp 4 and / or the bumper assembly of the engine cover 2 in the horizontal direction, so as to fix the position of the sealing structure on the vehicle and ensure the connection performance.
[0050] In some embodiments, referring to Figure 5As shown, the sealing body 1 is formed with a deformation cavity 14 on the portion avoiding the plug-in part 11, and the first sealing part 12 and the second sealing part 13 are formed on the wall surface of the deformation cavity 14 to interfere with the engine cover 3 and the vehicle lamp 4 and / or the bumper assembly through the deformation of the deformation cavity 14.
[0051] It can be understood that, by arranging the deformation cavity 14, the wall surface of the deformation cavity 14 can be deformed, and thus the first sealing part 12 formed on the wall surface of the deformation cavity 14 can interfere with the engine cover 3, i.e., the first sealing part 12 can abut against the engine cover 3 to achieve sealing, and the second sealing part 13 formed on the wall surface of the deformation cavity 14 can also interfere with the vehicle lamp 4 and / or the bumper assembly, i.e., the second sealing part 13 can abut against the vehicle lamp 4 and / or the bumper assembly to achieve sealing, and thus the sealing at the joint can be achieved.
[0052] Further, through the deformation of the first sealing part 12 and the second sealing part 13, the force when the engine cover 3 is closed can be further buffered, and the service life of the vehicle can be ensured.
[0053] Specifically, the interference amount between the first sealing part 12 and the engine cover 3 and the interference amount between the second sealing part 13 and the vehicle lamp 4 and / or the bumper assembly is between 0.5 mm and 1.0 mm, and in specific implementation, the interference amount can be 0.5 mm, 0.6 mm, 0.8 mm or 1.0 mm, which can be appropriately adjusted according to specific requirements, and the present application does not limit this. In this way, on the one hand, the joint can be weakened, and the visual delicate perception can be improved, and on the other hand, the whistling noise caused by the wind flowing into the joint when the vehicle is running at high speed can be solved, and the NVH characteristics of the vehicle can be improved.
[0054] In specific implementation, the first sealing part 12 and the second sealing part 13 are two regions formed on the wall surface of the deformation cavity 14, so as to ensure the abutting area between the first sealing part 12 and the engine cover 3 and between the second sealing part 13 and the vehicle lamp 4 and / or the bumper assembly.
[0055] In some embodiments, the wall surface of the deformation cavity 14 is provided with an exhaust hole 141, which communicates the inside and outside of the deformation cavity 14. When the deformation cavity 14 is extruded, the air in the deformation cavity 14 can be discharged through the exhaust hole 141, so as to avoid the air pressure in the deformation cavity 14 being too large due to excessive pressure, and thus the deformation of the first sealing part 12 and the second sealing part 13 can be better buffered. Specifically, the diameter of the exhaust hole 141 can be 4 mm, which can be arranged according to actual requirements.
[0056] Reference Figure 1 and Figure 2As shown, the number of exhaust holes 141 is multiple, multiple exhaust holes 141 are arranged along the extension direction of the sealing body 1, and the distance between adjacent exhaust holes 141 is between 120mm and 180mm, specifically, the distance between adjacent exhaust holes 141 can be 120mm, 140mm, 140mm or 180mm, which can be appropriately adjusted according to specific needs.
[0057] In some embodiments, with reference to Figure 5 As shown, the slot wall of the insertion slot 111 on the side surface of the cabin cover 2 is provided with a first clamping groove 112, and the first clamping groove 112 is used for clamping and limiting the first limiting protrusion 21 on the side surface of the cabin cover 2, so as to enhance the connection strength between the insertion slot 111 and the cabin cover 2, and avoid falling off.
[0058] The slot wall of the insertion slot 111 on the other side surface of the cabin cover 2 is provided with a second clamping groove 113, and the second clamping groove 113 is used for clamping and limiting the second limiting protrusion 22 on the other side surface of the cabin cover 2, so as to enhance the connection strength between the insertion slot 111 and the cabin cover 2, and avoid falling off.
[0059] That is, the first limiting protrusion 21 and the second limiting protrusion 22 on the two side surfaces of the cabin cover 2 can be clamped in the first clamping groove 112 and the second clamping groove 113 on the corresponding side, so as to enhance the connection strength between the insertion slot 111 and the cabin cover 2 through clamping and cooperation, that is, the first limiting protrusion 21 can abut against the slot wall of the first clamping groove 112, and the second limiting protrusion 22 can abut against the slot wall of the second clamping groove 113, so as to avoid the insertion part 11 from falling off the cabin cover 2.
[0060] Specifically, the first clamping groove 112 is formed as a groove structure on one side wall of the insertion slot 111, and the first limiting protrusion 21 can be correspondingly clamped into the groove structure, and the second clamping groove 113 is formed as a groove structure on the other side wall of the insertion slot 111, and the second limiting protrusion 22 can be correspondingly clamped into the groove structure, so as to limit the first limiting protrusion 21 by the slot wall of the first clamping groove 112, and limit the second limiting protrusion 22 by the slot wall of the second clamping groove 113.
[0061] In some embodiments, a sealing lip 114 is arranged at the slot opening of the first clamping groove 112 and / or the slot opening of the second clamping groove 113, and the sealing lip 114 is interferingly matched with the surface of the cabin cover 2, so as to realize the sealing between the sealing lip 114 and the surface of the cabin cover 2, and realize the effect of preventing water and soil from entering.
[0062] It can be understood that by arranging the sealing lip 114, the friction between the sealing lip 114 and the cabin cover 2 can be further increased, so as to avoid the insertion part 11 from falling off the cabin cover 2, and improve the connection strength.
[0063] Specifically, the sealing lip 114 can be arranged at the slot opening of the first clamping slot 112, at the slot opening of the second clamping slot 113, or at both slot openings of the first clamping slot 112 and the second clamping slot 113, which can be arranged according to actual needs. Further, the sealing lip 114 protrudes from the slot opening of the first clamping slot 112 or the slot opening of the second clamping slot 113, so that the sealing lip 114 can abut against the cabin cover 2 to form an interference fit therebetween, thereby ensuring the sealing effect.
[0064] For example, referring to FIG. 1, Figure 5 As shown in FIG. 1, the slot opening of the first clamping slot 112 is provided with the sealing lip 114, and the sealing lip 114 divides the space in the first clamping slot 112 into two parts, the first limiting protrusion 21 can be clamped into a part of the region close to the slot opening of the insertion slot 111, and the sealing lip 114 abuts against the cabin cover 2 to seal the other part of the region.
[0065] In some embodiments, the opposite side walls of the slot opening of the insertion slot 111 are formed into the first guide wall 115 and the second guide wall 116, respectively, the first guide wall 115 guides the clamping of the first limiting protrusion 21 into the first clamping slot 112, and the second guide wall 116 guides the clamping of the second limiting protrusion 22 into the second clamping slot 113. That is, the first guide wall 115 and the second guide wall 116 are both formed into inclined wall surfaces, and the first guide wall 115 and the second guide wall 116 are arranged at an included angle. In this way, the size of the slot opening of the insertion slot 111 can be enlarged to facilitate the insertion with the cabin cover 2, reduce the difficulty of insertion, and facilitate the clamping of the first limiting protrusion 21 into the first clamping slot 112 and the clamping of the second limiting protrusion 22 into the second clamping slot 113, thereby ensuring the smoothness of the insertion and improving the installation efficiency.
[0066] In specific implementation, the insertion slot 111 gradually shrinks in the direction from the slot bottom to the slot opening, so that the slot opening of the insertion slot 111 can be pressed against the cabin cover 2 to ensure the connection effect between the insertion slot 111 and the cabin cover 2 and avoid the sealing structure from being detached from the cabin cover 2.
[0067] In some embodiments, the first sealing portion 12 and the second sealing portion 13 are formed into the sponge rubber section 15, and the insertion portion 11 is formed into the dense rubber section 16.
[0068] In a specific implementation, the sealing body 1 is formed by an extrusion molding process and is divided into two sections according to material composition. One section is an EPDM dense rubber section, i.e., at least the insertion portion 11 is formed as a dense rubber section 16. The structure part that cooperates with the engine cover 3 is made of dense rubber with a relatively large hardness to meet the requirement of stable installation, and the hardness range is between 75 Shore and 85 Shore. The other section is an EPDM sponge rubber section, i.e., at least the first sealing portion 12 and the second sealing portion 13 are formed as a sponge rubber section 15. The structure part that mainly cooperates with the engine cover panel, the vehicle lamp 4, or the bumper assembly is made of sponge rubber with a relatively small hardness, and the density is between 0.50 g / cm and 0.80 g / cm.
[0069] In this way, the vehicle lamp 4 can be prevented from being damaged when the engine cover is closed, and the problem of difficult closing of the engine cover due to the interference of the sealing structure with the section with a large hardness can also be avoided.
[0070] The outer surface of the sealing body 1 is covered with a wear-resistant coating. Specifically, the wear-resistant coating is a polyurethane spray coating, and the thickness of the wear-resistant coating is between 10 μm and 16 μm, which can play a role in preventing wear and tear. In a specific implementation, the wear-resistant coating at least covers the outer surfaces of the first sealing portion 12 and the second sealing portion 13. When the first sealing portion 12 cooperates with the engine cover 3 and the second sealing portion 13 cooperates with the vehicle lamp 4 and / or the bumper assembly, both can have good wear resistance.
[0071] Some other embodiments of the present application provide a vehicle including an engine cover 3, a vehicle lamp 4, a bumper assembly, a cabin cover 2, and a sealing structure according to any one of the above embodiments. The vehicle lamp 4 is arranged on both sides of the bumper assembly. The sealing structure is installed on the cabin cover 2 and cooperates with the engine cover 3 and the vehicle lamp 4 and / or the bumper assembly.
[0072] The vehicle provided by the embodiments of the present application has the beneficial effects of the sealing structure according to any one of the above embodiments, and thus the detailed description is omitted here.
[0073] In a specific implementation, the sealing structure can seal the gap between the engine cover 3 and the vehicle lamp 4 and / or the gap between the engine cover 3 and the bumper assembly, so as to avoid the whistling noise caused by the inflow of wind at the gap. The sealing body 1 can be directly inserted and installed at the front end of the cabin cover 2, without the need to additionally provide a buckle structure on the engine cover 3, which is simple to operate and convenient to install.
[0074] Reference Figure 5As shown, the insertion groove 111 extends horizontally along the direction from the slot opening to the slot bottom, and the insertion groove 111 is inserted into the front end edge of the cabin cover 2 along the horizontal direction. That is, the insertion groove 111 is arranged to extend towards the cabin cover 2 along the horizontal direction, and the insertion groove 111 can be inserted and installed on the front end of the cabin cover 2 along the XY plane, that is, the sealing body 1 can be inserted and installed on the front end of the cabin cover 2 along the horizontal direction, so as to shorten the Z-direction application space and improve the overall arrangement.
[0075] Of course, it should be pointed out that the insertion direction of the insertion groove 111 can also be a direction at a smaller angle with the horizontal direction, and the present application does not limit this, as long as the Z-direction application space can be shortened and the insertion groove 111 can be conveniently inserted into the front end edge of the cabin cover 2.
[0076] In some embodiments, a first limiting protrusion 21 is arranged on one side surface of the cabin cover 2, and a first guide inclined surface 211 is formed on the side of the first limiting protrusion 21 facing the insertion direction of the insertion groove 111, the first guide inclined surface 211 can be slidably connected with the first guide wall 115 to drive the first limiting protrusion 21 to be clamped into the first clamping groove 112, thereby ensuring smooth installation, and a first limiting surface 212 is formed on the side of the first limiting protrusion 21 away from the insertion direction of the insertion groove 111, so as to limit the first limiting protrusion 21 from being pulled out of the first clamping groove 112 through the first limiting surface 212, thereby ensuring the connection strength.
