[0026] The sealing strip of the vehicle front compartment is arranged on the bottom side of the front compartment cover plate, which is used to block the dust, moisture and the like from the outside into the engine compartment. In the related art, with reference to Figure 1, the rear end of the sealing strip abuts against the front hood plate of the vehicle, and a large cavity X is formed between the front end of the sealing strip and the front hood plate. It is proposed in the application that the cavity X will cause strong high-speed airflow sound when the vehicle is running at high speed.

[0027] To solve the above problems, the sealing strip of the embodiment of the application is proposed. Referring to Figure 2 and Figure 3 , the sealing strip 1 of the embodiment of the application is formed with a wind-blocking surface 1111 on one side of the width direction, and a wind-guiding surface 1121 on the top side. The wind-guiding surface 1121 is connected to the wind-blocking surface 1111.

[0028] In the embodiment, the specific structure of the sealing strip 1 is not limited. As an example, the sealing strip 1 can be a hollow structure, so that the sealing strip 1 can be compressed and rebounded to realize the closing and sealing of the front hood plate 2. For example, referring to Figure 2 , the sealing strip 1 can include a base 12 and a barrier 11, which are butted and surrounded along the height direction of the sealing strip 1 to form a sealing cavity 1a extending along the length direction of the sealing strip 1. As another example, the sealing strip 1 can be a non-hollow structure and be made of a resilient material such as foamed sponge or silica gel, so that it can be compressed and rebounded.

[0029] Referring to Figure 3 , the sealing strip 1 is specifically arranged on the bottom side of the front hood plate 2 of the vehicle. Here, the front hood plate 2 specifically refers to a cover plate for opening or closing the front compartment of the vehicle. For example, in a fuel vehicle, a range-extended vehicle, or a plug-in hybrid vehicle, the front hood plate 2 can be an engine cover plate. For example, in a pure electric vehicle, the front hood plate 2 can be a front spare compartment cover plate.

[0030] In the embodiment shown in Figure 3 , the top of the sealing strip 1 abuts against the bottom surface of the front hood plate 2, and the bottom abuts against the vehicle lamp assembly 3. However, those skilled in the art can understand that, in addition to abutting against the vehicle lamp assembly 3, the bottom of the sealing strip 1 can also abut against other structures on the bottom side of the front hood plate 2, such as an air intake grille, and the like. Those skilled in the art can determine according to the specific architecture of the vehicle.

[0031] In actual use, the length direction (the direction perpendicular to the paper) of the sealing strip 1 is substantially parallel to the left-right direction of the vehicle, the width direction (the direction indicated by the arrow L1 in the figure) of the sealing strip 1 is substantially parallel to the front-rear direction of the vehicle, and the height direction (the direction indicated by the arrow L2 in the figure) of the sealing strip 1 is substantially parallel to the height direction of the vehicle.

[0032] In this embodiment, the one side outer surface of the sealing strip 1 in the width direction is formed as a wind blocking surface 1111. Specifically, the one side outer surface of the sealing strip 1 facing the front side of the vehicle in actual use is formed as the wind blocking surface 1111. Taking the sealing strip 1 including the base 12 and the blocking strip 11 as an example, the blocking strip 11 can include a wind blocking wall 111, and the one side surface of the wind blocking wall 111 facing away from the sealing cavity 1a is formed as the wind blocking surface 1111.

[0033] The top side outer surface of the sealing strip 1 is formed as a wind guiding surface 1121, and the wind guiding surface 1121 is connected with the wind blocking surface 1111. Here, the wind guiding surface 1121 can be a flat surface or an arc surface, and no limitation is made thereto.

[0034] Still taking the sealing strip 1 including the blocking strip 11 and the base 12 as an example, the blocking strip 11 can form a wind guiding wall 112, and the one side surface of the wind guiding wall 112 facing away from the sealing cavity 1a is formed as the wind guiding surface 1121.

[0035] Comparison Figure 1 and Figure 3 It can be seen that the top side surface of the sealing strip in the related art is formed as an arc surface to guide the flow of air flow, and this arrangement causes a large cavity X to exist between the front of the sealing strip and the front end of the front hood panel of the vehicle. During driving of the vehicle, especially during high-speed driving, the air flow in the cavity X will cause a large noise.

[0036] In this embodiment, the front side of the sealing strip 1 is additionally provided with the wind blocking surface 1111, so that the volume of the cavity between the sealing strip 1 and the front hood panel 2 of the vehicle can be reduced in actual use, and the air flow can be better blocked. Further, the top side of the sealing strip 1 is formed as the wind guiding surface 1121, and the air flow that cannot be effectively blocked by the wind blocking surface 1111 can flow relatively orderly under the guidance of the wind guiding surface 1121. The two cooperate with each other to reduce the intensity of the high air flow sound when the vehicle is driven at high speed. It has been proved by actual measurement that the sound pressure level of the high-speed air flow of the sealing strip 1 of the embodiment of the present application is reduced by about 2dBA compared with the related art in the frequency band of 2500-4000Hz.

[0037] In some embodiments, with reference to Figure 3 , the top end of the wind blocking surface 1111 is used to abut against the front hood panel 2 of the vehicle, so that the volume of the cavity between the sealing strip 1 and the front hood panel 2 can be further reduced, thereby further reducing the high air flow sound.

[0038] As an example, the bottom side of the front hood panel 2 can be provided with a sealing rubber strip 21 extending in the left-right direction of the vehicle, and the sealing strip 1 can specifically abut against the sealing rubber strip 21. Of course, the top end of the wind blocking surface 1111 can also abut against other structures on the bottom surface of the front hood panel 2, and no limitation is made thereto.

[0039] Further, in the embodiment, the sealing strip 1 can be fixed on a certain vehicle structure (for example, the headlamp assembly 3) at the bottom side of the front hood panel 2, and the top end of the wind-blocking surface 1111 abuts against the front hood panel 2 in the case where the front hood panel 2 is closed.

[0040] In some other embodiments, the top end of the wind-blocking surface 1111 can also leave a certain gap with the bottom side surface of the front hood panel 2, and in such an embodiment, the top side outer surface of the sealing strip 1 can abut against the bottom surface of the front hood panel 2.

[0041] In some embodiments, the wind-blocking surface 1111 is parallel to the height direction of the sealing strip 1, or the included angle between the wind-blocking surface 1111 and the height direction of the sealing strip 1 is less than or equal to 15°.

[0042] It can be understood that the wind-blocking surface 1111 can be a plane or an arc surface, and in the case where the wind-blocking surface 1111 is an arc surface, the included angle between the wind-blocking surface 1111 and the height direction of the sealing strip 1 should be understood as the included angle between the tangent surface of the wind-blocking surface 1111 and the height direction of the sealing strip 1.

[0043] In some embodiments, referring to Figure 2 and Figure 3 , the wind-guiding surface 1121 extends obliquely towards the bottom side of the sealing strip 1 in the direction away from the wind-blocking surface 1111.

[0044] In the embodiment, the wind-guiding surface 1121 extends obliquely towards the bottom side of the sealing strip 1, so that the entering airflow can be guided into the engine compartment (or the front trunk), thereby further reducing the airflow sound generated by the airflow.

[0045] In some embodiments, the wind-guiding surface 1121 has an abutting area for abutting against the vehicle structure, in particular, the wind-guiding surface 1121 has an abutting area for abutting against the front hood panel 2. In this way, the sealing effect of the sealing strip 1 can be further improved.

[0046] As mentioned above, the top end of the wind-blocking surface 1111 can be used to abut against the front hood panel 2, and in such an embodiment, the top end of the wind-blocking surface 1111 and the abutting area of the wind-guiding surface 1121 can both abut against the front hood panel 2.

[0047] As an example, referring to Figure 3 , the bottom side surface of the front hood panel 2 can be partially raised to form a raised portion 2a, the front side of the raised portion 2a is provided with a sealing rubber strip 21, the wind-blocking surface 1111 is located at the front side of the raised portion 2a and abuts against the sealing rubber strip 21, and the abutting area of the wind-guiding surface 1121 abuts against the raised portion 2a.

[0048] In some embodiments, referring to Figure 2 and Figure 3The bottom side outer surface of the sealing strip 1 is formed as a support surface 1211, which includes, along the width direction of the sealing strip 1, a first portion 1211a, a second portion 1211b and a third portion 1211c connected in sequence, the first portion 1211a and the third portion 1211c extend along the width direction of the sealing strip 1, and the second portion 1211b extends along the height direction of the sealing strip 1, and the wind blocking surface 1111 is connected with the third portion 1211c.

[0049] In the embodiment, the support surface 1211 of the bottom side of the sealing strip 1 extends in an L shape, which helps to improve the assembly stability of the sealing strip 1. In actual use, the structure of the bottom side of the front hatch plate 2 can be provided with a step structure matched with the support surface 1211, and the support surface 1211 can abut against the step structure.

[0050] Taking the sealing strip 1 including the base 12 and the blocking strip 11 as an example, the base 12 can include a support wall 121, and a side surface of the support wall 121 away from the sealing cavity 1a is formed as the support surface 1211.

[0051] In some embodiments, specifically, the third portion 1211c is located at the top side of the first portion 1211a and is formed as a shielding surface, which will make the height dimension of the sealing strip 1 at the position corresponding to the third portion 1211c smaller than the height dimension at the position corresponding to the first portion 1211a, improve the local rigidity of the sealing strip 1 at the wind blocking surface 1111, and further improve the wind blocking effect of the wind blocking surface 1111.

[0052] Further, the third portion 1211c can shield the exposed surface of the vehicle body structure in actual use, thereby helping to improve the aesthetic level of the vehicle. Taking the sealing strip 1 used between the front hatch plate 2 and the vehicle lamp assembly 3 as an example, Figure 3 The third portion 1211c is used to shield at least part of the vehicle lamp exposed surface 3a at the top side of the vehicle lamp assembly 3. The vehicle lamp exposed surface 3a at the top side of the vehicle lamp assembly 3 herein should be understood as the part that can be observed at the top side of the vehicle lamp when the front hatch plate 2 is closed and the sealing strip 1 is not arranged. In the embodiment, the third portion 1211c can shield at least part of the vehicle lamp exposed surface 3a at the top side of the vehicle lamp assembly 3, which can improve the aesthetic level of the vehicle.

[0053] In some embodiments, the bottom end of the wind blocking wall 111 is connected with the base 12, and the bottom end of the wind blocking wall 111 forms a weakened structure extending along the length direction of the sealing strip 1.

[0054] It can be understood that the sealing strip 1 will contract and rebound during the process of lowering the front hood panel 2, and since the wind deflector 111 has a certain structural strength and the local rigidity at the position of the wind deflector 111 is increased by the L-shaped support surface 1211 in some embodiments described above, a strong rebound force will be generated at this position. Therefore, in this embodiment, a weakening structure is further formed at the bottom end of the wind deflector 111, so that the rebound force generated by the sealing strip 1 during the process of lowering the front hood panel 2 can be reduced, which helps to close the front hood panel 2.

[0055] The specific structural form of the weakening structure is not limited, such as a groove structure extending along the length direction of the sealing strip 1, or a thinning structure arranged at intervals along the length direction of the sealing strip 1, etc.

[0056] In some embodiments, the weakening structure specifically includes a weakening groove 1112, which is recessed from the side surface of the wind deflector 111 facing the sealing cavity 1a, and the bottom side groove wall of the weakening groove 1112 is connected to the base 12. The weakening groove 1112 adopted in this embodiment can effectively reduce the rebound force generated by the wind deflector 111 during the process of lowering the front hood panel 2, and can also maintain good rigidity of the wind deflector 111 during normal use.

[0057] In some embodiments, with reference to Figure 2 and Figure 3 , the base 12 further includes a connecting strip 122 arranged on the side of the support wall 121 away from the sealing cavity 1a, and the connecting strip 122 extends along the length direction of the sealing strip 1. Taking the support surface 1211 of the support wall 121 as an example, the support surface 1211 includes a first portion 1211a, a second portion 1211b and a third portion 1211c, and the connecting strip 122 can be arranged on the first portion 1211a.

[0058] The connecting strip 122 is used to connect with the structure on the bottom side of the front hood panel 2, such as the vehicle lamp assembly 3, so as to fix the sealing strip 1 with the vehicle lamp assembly 3. The specific structural form of the connecting strip 122 is not limited, such as a glue strip, a magic tape, etc.

[0059] Embodiments of the present application also provide a vehicle front compartment assembly, with reference to Figure 3 , the vehicle front compartment assembly includes a front hood panel 2, a vehicle lamp assembly 3 and a sealing strip 1 as described in any one of the above embodiments. The vehicle lamp assembly 3 is arranged on the bottom side of the front hood panel 2, and the sealing strip 1 is arranged between the front hood panel 2 and the vehicle lamp assembly 3.

[0060] The vehicle front compartment assembly of the present embodiment has all the advantages of the sealing strip 1 as described in any one of the above embodiments, which will not be repeated here.

[0061] In the embodiment, the specific structure of the sealing strip 1 and the matching connection relationship between the sealing strip 1 and the front hood plate 2 and the lamp assembly 3 can refer to the description of the related parts in the above.
