[0035] Referring to Figure 1 With Figure 2 As shown in the figure, according to the utility model embodiments of a kind of engine hood front sealing strip, including body 110 and connecting piece 120.

[0036] Specifically, the body 110 is provided with an abutting portion 1121. In work, the body 110 has a extrusion state, in the extrusion state, the abutting portion 1121 is in abutment with the front skin 200 of the engine hood. The body 110 has a contact surface 1122 and a mounting surface 1111, when the body 110 is in the extrusion state, the contact surface 1122 is in abutment with the engine hood 210. So as to seal the engine compartment. As Figure 1As shown, the engine hood is closed at this time. The engine hood 210 abuts against the contact surface 1122 and applies pressure to the body 110, causing the body 110 to deform. The abutting part 1121 moves to the right and abuts against the front skin 200. The engine front cover 220 and the front skin 200 are sealed by the engine hood front sealing strip to achieve the purpose of dustproof, waterproof and noise reduction.

[0037] The mounting surface 1111 is adapted to abut against the engine front cover 220. The mounting surface 1111 is provided with a first positioning scale 1112 and two second positioning scales 1113. The first positioning scale 1112 and the second positioning scale 1113 both extend along the length direction of the body 110. Figure 2 As shown, the length direction of the body 110 is perpendicular to the paper surface. The first positioning scale 1112 and the second positioning scale 1113 can be lines drawn on the mounting surface 1111, or the first positioning scale 1112 and the second positioning scale 1113 can be groove-shaped structures on the mounting surface 1111. For example, in Figure 2 In the example, the first positioning scale 1112 is a groove with an upright triangular cross-section. Two second positioning scales 1113 are spaced apart, with the first positioning scale 1112 located between the two second positioning scales 1113. The body 110 has at least two mounting holes 114, which are distributed along the length of the body 110, and the center of the mounting hole 114 is located on the first positioning scale 1112. During the manufacturing process, the first positioning scale 1112 is used to position the machining process of the mounting hole 114, reducing the positioning error of the mounting hole 114.

[0038] The outer peripheral wall of the connector 120 is provided with a positioning protrusion 121. The positioning protrusion 121 can be an annular structure extending along the circumferential direction of the connector 120, or the positioning protrusion 121 can be a protrusion. The connector 120 passes through the mounting hole 114 and is inserted into the engine front cover plate 220 to connect the body 110 and the engine front cover plate 220. The positioning protrusion 121 abuts against the mounting surface 1111 and the top surface of the engine front cover plate 220, and is sandwiched between the mounting surface 1111 and the top surface of the engine front cover plate 220. The positioning protrusion 121 positions the connection position between the connector 120 and the engine front cover plate 220. Figure 1 and Figure 3As shown, the distance L3 between the two second positioning scales 1113 is less than or equal to the width L0 of the positioning protrusion 121. In this way, whether the installation position degree of the engine hood front sealing strip on the engine hood meets the requirement can be judged by the installation of the connecting piece 120. When assembling the body 110 and the connecting piece 120, the connecting piece 120 is inserted into the mounting hole 114, and the positioning protrusion 121 is abutted against the mounting surface 1111. When the positioning protrusion 121 covers the two second positioning scales 1113, the engine hood front sealing strip can meet the installation position degree requirement. When the positioning protrusion 121 cannot cover the two second positioning scales 1113, the engine hood front sealing strip cannot meet the installation position degree requirement, and a gap between the abutting portion 1121 and the front skin 200 in the extrusion state or the body 110 being too close to the front skin 200 to cause excessive interference between the abutting portion 1121 and the front skin 200 when the engine hood front sealing strip is installed, the abutting portion 1121 is upturned, and the abutting portion 1121 is not in stable contact with the front skin 200 after the engine hood is closed.

[0039] It can be understood that the engine hood front sealing strip is not in the extrusion state when installed, the mounting surface 1111 is installed downward, and the position degree of the engine hood front sealing strip cannot be well controlled when the engine hood front sealing strip is installed due to the limitation of the limited space of the engine compartment. The position of the engine hood front sealing strip in the left-right direction (for example, the direction shown in FIG. 1) is prone to have a large error, and the engine hood front sealing strip is not installed in place, thereby causing the abutting portion 1121 to not be in good contact with the front skin 200, poor sealing of the engine compartment, and easy generation of vibration noise. Figure 1 The first positioning scale 1112 is used for positioning the machining of the mounting hole 114, and whether the positioning protrusion 121 covers the second positioning scale 1113 is used for judging the installation position degree of the engine hood front sealing strip when the connecting piece 120 and the body 110 are assembled, so as to avoid the above problems and improve the sealing of the engine compartment and reduce vibration noise.

[0040] According to the engine hood front sealing strip provided in the embodiments of the present application, the first positioning scale 1112 is used for positioning the machining of the mounting hole 114, and whether the positioning protrusion 121 covers the second positioning scale 1113 is used for judging the installation position degree of the engine hood front sealing strip when the connecting piece 120 and the body 110 are assembled, so as to avoid the above problems and improve the sealing of the engine compartment and reduce vibration noise.

[0041] According to some embodiments of the present application, the engine hood front sealing strip is an elastic member, and in the extrusion state, the abutting portion 1121 is compressed, so that the abutting portion 1121 generates a certain elastic force to keep abutting with the front skin 200. Figure 1 AndFigure 3 As shown, the length of the abutment portion 1121 of the front hood sealing strip in its naturally extended state is L1, and in the compressed state, the length of the abutment portion 1121 is L2, where 0.5mm ≤ L1 - L2 ≤ 1.5mm. For example, L1 - L2 can be 0.5mm, 0.8mm, 1mm, or 1.5mm. That is, after the hood 210 abuts against the contact surface 1122, the body 110 deforms, causing the abutment portion 1121 to approach and abut against the front skin 200. There is an interference amount of L1 - L2 between the abutment portion 1121 and the front skin 200, and the abutment portion 1121 is compressed. This ensures that during vehicle operation, even after the front hood sealing strip undergoes a certain deformation under stress, the abutment portion 1121 still abuts against the front skin 200, thus ensuring the sealing of the engine compartment and reducing vibration.

[0042] According to some embodiments of this utility model, the difference between the width L0 of the positioning protrusion 121 and the distance L3 between the two second positioning scales 1113 is less than or equal to 2*(L1-L2), such as... Figure 3 As shown, L3 is the distance between the two second positioning scales 1113, and L0-L3≤2*(L1-L2). This is to ensure that the installation position of the body 110 can meet the interference requirements between the abutment part 1121 and the front skin 200.

[0043] According to some embodiments of this utility model, the contact surface 1122 is an arc-shaped surface recessed towards the interior of the body 110, thereby creating a certain gap between the contact surface 1122 and the top surface of the engine hood cover 220 to accommodate the positioning protrusion 121. This prevents the body 110 from being pushed up by the fixing protrusion after the engine hood front sealing strip is installed, thus improving the installation stability of the engine hood front sealing strip and reducing vibration. Furthermore, the arc-shaped contact surface 1122 can be formed during extrusion molding or injection molding, resulting in a simple production process and low cost.

[0044] like Figure 2 As shown, according to some embodiments of the present invention, a clearance groove 1114 is provided on the mounting surface 1111. The width of the clearance groove 1114 is greater than the width L0 of the positioning protrusion 121. The positioning protrusion 121 is housed in the clearance groove 1114, thereby preventing the main body 110 from being pushed up by the fixing protrusion after the engine hood front sealing strip is installed, which would cause the installation to be incomplete, thus improving the installation stability of the engine hood front sealing strip and reducing vibration.

[0045] According to some embodiments of this utility model, the width L4 of the clearance groove 1114 is smaller than the width L5 of the mounting surface 1111. Support feet 1115 are formed between the two sides of the clearance groove 1114 and the two side edges of the mounting surface 1111, respectively. The support feet 1115 are used to abut against the engine front cover plate 220. Figure 2As shown, support feet 1115 are formed on the left and right sides of the mounting surface 1111 respectively. The support feet 1115 abut against the engine front cover plate 220. When the engine cover 210 is closed, the engine cover 210 applies downward pressure to the body 110, causing the two support feet 1115 to undergo a certain displacement and deformation, which puts pressure on the positioning protrusion 121, making it press tightly against the engine front cover plate 220.

[0046] According to some embodiments of this utility model, the body 110 includes a base 111 and a support portion 112, with the two ends of the body 110 and the two ends of the support portion 112 correspondingly connected, such as... Figure 2 As shown, the left end of the base 111 is connected to the left end of the support 112, and the right end of the base 111 is connected to the right end of the support 112. The base 111 and the support 112 can be integrally formed or bonded together. A deformation cavity 113 is formed between the base 111 and the support 112, allowing the body 110 to have a large deformation range. The mounting surface 1111 is located on the bottom surface of the base 111. The support 112 is arched, and the contact surface 1122 and the abutment part 1121 are both located on the support 112. When the engine hood 210 abuts against the mounting surface 1111, pressure is applied to the support 112, causing the arched support 112 to deform, thereby causing the abutment part 1121 to abut tightly against the front skin 200, improving the sealing performance.

[0047] According to some embodiments of this utility model, the contact surface 1122 and the abutment portion 1121 are located on the same side of the support portion 112, and the angle between the side containing the contact surface 1122 and the abutment portion 1121 and the vertical direction is greater than the angle between the other side and the vertical direction. For example... Figure 2 and Figure 3 As shown, the arched support 112 has a ridge 1123 at its highest point. Both the contact surface 1122 and the abutment portion 1121 are located on the right side of the ridge 1123. The angle between the right side of the ridge 1123 and the vertical direction is A1, where A1 > 45°. It is understood that A1 < 90°. Thus, the horizontal component of the pressure applied by the engine hood 210 to the contact surface 1122 is less than its vertical component, ensuring close contact between the abutment portion 1121 and the front skin 200 during vehicle movement, thereby improving sealing.

[0048] A vehicle according to an embodiment of the present invention includes a front skin 200, an engine hood 210, an engine compartment cover 220, and an engine hood front sealing strip as described above. A connector 120 for the engine hood front sealing strip passes through a mounting hole 114 on the body 110 and is inserted into the engine compartment cover 220 to connect the engine hood front sealing strip to the engine compartment cover 220. During operation, the body 110 is in a compressed state, the engine hood 210 abuts against the contact surface 1122, and the abutting portion 1121 abuts against the front skin 200 to seal the engine compartment.

[0049] In summary, the engine hood front sealing strip provided by the embodiments of the present application has at least the following beneficial effects:

[0050] 1. The installation position degree of the engine hood front sealing strip is improved, and installation is convenient;

[0051] 2. The engine hood front sealing strip has good installation stability and sealing performance, and reduces vibration and noise generated during vehicle driving.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the present application, and are not a limitation on the present application. It should be noted that for ordinary skilled persons in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
