[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0023] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0024] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0025] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0026] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0027] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0028] This application provides a vehicle. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. For a vehicle, a sealing strip needs to be installed between the front engine compartment and the hood to prevent water or dust from the external environment from entering the front engine compartment. However, the mounting structure of the sealing strip in related technologies requires a metal frame to support the installation of the sealing strip. However, installing a metal frame inside the sealing strip not only increases the difficulty of the manufacturing process but also increases the cost of the sealing strip.

[0029] Based on this, this application provides a sealing assembly, which includes a mounting member 10 and a sealing strip 20. The mounting member 10 is connected to the front engine compartment and can be part of the front engine compartment, specifically a front engine compartment trim piece. The sealing strip 20 is located between the front engine compartment and the hood 40 to seal the gap between them. Specifically, the sealing strip 20 is located between the rear end of the front engine compartment and the hood 40 to prevent water flowing down from the windshield from entering the front engine compartment.

[0030] Mounting component 10 has a first mounting portion 1, and sealing strip 20 includes a second mounting portion 2 and a sealing portion 3. Sealing portion 3 is connected to the second mounting portion 2. Specifically, sealing portion 3 is connected to the upper end of the second mounting portion 2. Sealing strip 20 is mounted to mounting component 10 through the second mounting portion 2, and sealing portion 3 seals between the front engine compartment and the hood 40.

[0031] The second mounting part 2 has a mounting cavity with the opening facing the mounting member 10. The first mounting part 1 is detachably embedded in the mounting cavity. The outer peripheral surface of the first mounting part 1 can be tightly fitted with the inner surface of the mounting cavity to fix the first mounting part 1 in the mounting cavity. The first mounting part 1 is interference-fitted with the mounting cavity, which further increases the firmness and reliability of the sealing strip 20 on the mounting member 10.

[0032] For example, the first mounting part 1 can be a mounting column or mounting plate connected to the forward engine compartment. Multiple mounting columns can be provided, and the multiple mounting columns can be arranged at intervals along the circumference of the forward engine compartment. One mounting plate can be provided, and one mounting plate extends along the circumference of the forward engine compartment. One sealing strip 20 can be provided, and one sealing strip 20 extends around the circumference of the forward engine compartment. One sealing strip 20 can be interference-fitted with multiple mounting columns, and one sealing strip 20 can also be interference-fitted with one mounting plate. Providing one sealing strip 20 can prevent water from seeping into the forward engine compartment due to discontinuities in the sealing strip 20.

[0033] For example, the second mounting part 2 can be a rubber component with high density and strength made of EPDM rubber, which can meet the strength requirements of the second mounting part 2 without the need for a metal skeleton. Furthermore, since the second mounting part 2 is a rubber component, it can be bent along both ends of the mounting cavity towards the cavity, increasing the dimension of the mounting cavity in the width direction of the sealing strip 20, thus facilitating the insertion of the first mounting part 1 into the mounting cavity.

[0034] The sealing assembly provided in this application embodiment has a first mounting part 1 on the mounting part 10 and a sealing strip 20 including a second mounting part 2 and a sealing part 3. The second mounting part 2 forms a mounting cavity, and the first mounting part 1 is detachably embedded in the mounting cavity and is interference-fitted with the mounting cavity. By eliminating the metal frame, not only can the cost of the sealing strip 20 be reduced, but the firmness and reliability of the sealing strip 20 installed on the mounting part 10 can also be increased.

[0035] Reference Figure 1 In one possible implementation of this application, a first snap-fit ​​portion is provided inside the mounting cavity, and a second snap-fit ​​portion is provided inside the first mounting portion 1. The second snap-fit ​​portion engages with the first snap-fit ​​portion to further increase the structural strength when the first mounting portion 1 is installed into the mounting cavity. When the vehicle vibrates, or when the hood 40 presses against the sealing strip 20, the engagement of the second snap-fit ​​portion with the first snap-fit ​​portion makes it less likely for the sealing strip 20 to fall off the first mounting portion 1.

[0036] For example, the first snap-fit ​​part can be a buckle provided in the mounting cavity, and the second snap-fit ​​part can be a hook provided on the second mounting part 2. By bending the second mounting part 2 toward both ends of the mounting cavity, the size of the mounting cavity in the width direction of the sealing strip 20 can be increased, so that the first mounting part 1 extends into the mounting cavity, and the second snap-fit ​​part engages with the first snap-fit ​​part.

[0037] Reference Figure 1In one possible implementation of this application, the second snap-fit ​​portion includes a protrusion 11, which is disposed on the second mounting portion 2. The first mounting portion 1 further includes a connecting plate 12 connected to the protrusion 11. In the vertical direction, the protrusion 11 can be connected to the upper end of the connecting plate 12. In the width direction of the sealing strip 20 (refer to the attached figure) Figure 1 In the X direction, the size of the protrusion 11 is larger than the size of the connecting plate 12. The mounting cavity includes a first cavity and a second cavity that are connected. The second cavity is located adjacent to the front engine compartment. The protrusion 11 is located in the first cavity, and the connecting plate 12 is located in the second cavity. Correspondingly, in order for the first mounting part 1 to be embedded in the mounting cavity, the size of the first cavity is larger than the size of the second cavity.

[0038] In the width direction of the sealing strip 20, the size of the protrusion 11 is larger than the size of the connecting plate 12. Correspondingly, the size of the first cavity is larger than the size of the second cavity. After the first mounting part 1 is installed into the mounting cavity, a limiting surface is formed on the side of the first cavity near the second cavity. The limiting surface abuts against the protrusion 11 to limit the position of the protrusion 11 and prevent the protrusion 11 from falling out of the first cavity. When the vehicle vibrates or the hood 40 presses the sealing strip 20, the limiting surface restricts the position of the protrusion 11 in the mounting cavity, making it difficult for the sealing strip 20 to fall off the first mounting part 1.

[0039] Reference Figure 1 In one possible implementation of this application, the bump 11 includes a bump body 111, a first protrusion 112 and a second protrusion 113. The first protrusion 112 and the second protrusion 113 are both connected along the bump body 111. The first protrusion 112 and the second protrusion 113 are arranged opposite to each other along the width direction of the bump body 111, and the first protrusion 112 and the second protrusion 113 both extend toward the inner wall of the first cavity, while the first protrusion 112 and the second protrusion 113 extend in opposite directions.

[0040] A first protrusion 112 and a second protrusion 113 are provided on the protrusion 11, and both the first protrusion 112 and the second protrusion 113 extend toward the inner wall of the first cavity. Multiple limiting surfaces are formed in the first cavity to limit the position of the first protrusion 112 and the second protrusion 113 in the first cavity. At the same time, the second mounting part 2 is interference-fitted with the mounting cavity. Under the combined action of the limiting structure and the interference fit, the fit strength between the protrusion 11 and the first cavity is further increased, which can further prevent the protrusion 11 from detaching from the first cavity.

[0041] Reference Figure 1In one possible implementation of this application, the protrusion 11 includes a first sidewall 114, a second sidewall 115, a third sidewall 116, and a fourth sidewall 117 connected in sequence. The end of the first sidewall 114 facing away from the second sidewall 115 is connected to the connecting plate 12, and the end of the fourth sidewall 117 facing away from the third sidewall 116 is also connected to the connecting plate 12. The included angle between the first sidewall 114 and the second sidewall 115 is an obtuse angle, the included angle between the second sidewall 115 and the third sidewall 116 is an obtuse angle, and the included angle between the third sidewall 116 and the fourth sidewall 117 is an acute angle. The protrusion 11 can be an irregular pentagon. The protrusion 11 is located in the first cavity and forms an embedded shape with the first cavity, that is, the inner wall of the first cavity fits with the outer surface of the protrusion 11. A first limiting surface that fits with the first sidewall 114 and a second limiting surface that fits with the fourth sidewall 117 are formed on the inner wall of the first cavity. Under the combined action of the first limiting surface and the second limiting surface, the position of the protrusion 11 in the first cavity can be restricted.

[0042] For example, the included angle formed between the first sidewall 114 and the second sidewall 115 can be the first protrusion 112, and the included angle between the third sidewall 116 and the fourth sidewall 117 can be the second protrusion 113.

[0043] In a specific example, a rounded corner 13 can be formed between the first sidewall 114 and the surface of the connecting plate 12, and a rounded corner 13 can also be formed between the fourth sidewall 117 and the surface of the connecting plate 12. This can avoid stress concentration and facilitate the protrusion 11 to extend into the first cavity.

[0044] Reference Figure 1 In one possible implementation of this application, a rounded corner 13 is formed between the connecting plate 12 and the protrusion 11, which can avoid stress concentration between the connecting plate 12 and the protrusion 11 and facilitate the protrusion 11 to be clamped to the inner wall of the first cavity.

[0045] Reference Figure 1 In one possible implementation of this application, the second mounting part 2 has a first side 21 and a second side 22 disposed along the width direction of the sealing strip 20. In the direction of the sealing part 3 toward the second mounting part 2, the first side 21 and the second side 22 extend toward each other, which can provide the second mounting part 2 with a pushing force toward each other, so that the second mounting part 2 can lock the first mounting part 1.

[0046] In a specific example, in the width direction of the sealing strip 20, the mounting cavity can divide the second mounting part 2 into a first part and a second part. The side of the first part facing away from the second part is the first side 21, and the side of the second part facing away from the first part is the second side 22. Both the first part and the end of the second part facing the mounting member 10 are formed with rounded corners 13 to avoid stress concentration.

[0047] Reference Figure 1 In one possible implementation of this application, the sealing part 3 is made of a foaming component. The sealing part 3 is processed by a foaming process, and multiple small holes are formed in the sealing part 3. When the sealing part 3 is compressed, it can produce a large deformation and fill the gap between the front engine compartment and the engine hood 40 after being squeezed, thereby improving its sealing performance.

[0048] The second mounting part 2 is made of a dense component. It is made of a high-density structure and a non-porous or low-porous material to increase the structural strength of the second mounting part 2. It can meet the strength requirements of the second mounting part 2 without the need to set a metal frame inside the second mounting part 2.

[0049] For example, the sealing strip 20 is a rubber part, the sealing part 3 is made of EPDM rubber using a foaming process, and the second mounting part 2 is made of EPDM rubber using a compaction process.

[0050] Reference Figure 1 In one possible implementation of this application, the sealing part 3 is provided with a cavity 31, which extends along the length of the sealing strip 20. When the front engine compartment presses the sealing part 3, the cavity 31 in the sealing part 3 is compressed, and the sealing part 3 undergoes a large deformation, which can fill the gap between the front engine compartment and the engine hood 40 after being squeezed, thereby improving its sealing performance.

[0051] For example, the sealing part 3 is a foam tube, which is connected to the second mounting part 2 on one radial side and connected to the upper end of the second mounting part 2.

[0052] Secondly, embodiments of this application provide a vehicle, including: a sealing assembly.

[0053] The vehicle provided in this application embodiment has the same technical effect because it includes the sealing component provided in any of the above-mentioned embodiments. That is, the first mounting part 1 is detachably embedded in the mounting cavity and is interference-fitted with the mounting cavity. By eliminating the metal frame, not only can the cost of the sealing strip 20 be reduced, but the firmness and reliability of the sealing strip 20 installed on the mounting part 10 can also be increased.

[0054] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
