[0040] Reference below Figure 1-Figure 3 The tie rod 100 according to an embodiment of the present invention is described. The tie rod 100 can transmit the impact force transmitted to one shock absorber of the vehicle during an offset collision to the other shock absorber, and the impact force transmitted to the tie rod 100 can be further transmitted to the upper part 201 of the front panel, thereby reliably dissipating the impact force, effectively reducing the deformation of the shock absorber, improving the overall stability and torsional rigidity of the vehicle, and improving the reliability of the impact force being transmitted from one shock absorber to the other shock absorber along the tie rod 100.

[0041] like Figure 1-Figure 3 As shown, according to an embodiment of the present invention, the tie rod 100 is suitable for being connected between two shock absorber towers 202 and is suitable for being connected to the front upper part 201 through a connecting structure 203, and the tie rod 100 includes: a tie rod body 1 and two connecting plate bodies 2.

[0042] The pull rod body 1 is provided with a first connecting portion 11, which is used to connect to the connecting structure 203. The two connecting plate bodies 2 are respectively connected to the two ends of the pull rod body 1, and the two connecting plate bodies 2 are respectively connected to the two shock absorber towers 202 in a one-to-one correspondence; wherein, the connecting plate body 2 is provided with at least three second connecting portions 21, and the second connecting portions 21 are used to connect to the shock absorber towers 202, and three of the at least three second connecting portions 21 are distributed in a triangle.

[0043] Specifically, the shock absorber tower 202 is installed at the top of the shock absorber and is used to fix the shock absorber, that is, the shock absorber tower 202 is connected to the shock absorber, and the tie rod 100 is connected between the two shock absorber towers 202, so that the tie rod 100 can be connected between the two shock absorbers, so that when the vehicle undergoes a polarized collision, the impact force received by one shock absorber can be transmitted along the tie rod 100 to the other shock absorber, thereby achieving the dissipation of the impact force and reducing the deformation of the shock absorber. At the same time, the tie rod 100 is connected to the upper part of the front panel 201 through the connecting structure 203, so that the impact force transmitted from the shock absorber to the tie rod 100 can be further transmitted along the connecting structure 203 to the upper part of the front panel 201, thereby further achieving the dissipation of the impact force, effectively reducing the deformation of the shock absorber, and improving the overall stability and torsional stiffness of the vehicle.

[0044] It should be noted that the shock absorber tower 202 in the present application may be a front shock absorber tower, and the shock absorber may be a front shock absorber.

[0045] Among them, the transverse tie rod 100 includes a tie rod body 1 and a connecting plate body 2, the tie rod body 1 is used to be connected to the connecting structure 203, and the connecting plate body 2 is used to be connected to the shock absorber tower 202, and there are two connecting plate bodies 2, and the two connecting plate bodies 2 are connected to the two shock absorber towers 202 respectively in a one-to-one correspondence, that is, for each shock absorber tower 202, a connecting plate body 2 is provided to be connected thereto, thereby improving the connection reliability between the transverse tie rod 100 and the shock absorber tower 202, that is, improving the connection reliability between the transverse tie rod 100 and the shock absorber, and, moreover, connecting the two connecting plate bodies 2 to the two ends of the tie rod body 1 respectively, can make the transverse tie rod 100 a whole, which is conducive to improving the overall structural strength and working reliability of the transverse tie rod 100, and the transverse tie rod 100 can be constructed to extend along the transverse direction of the vehicle, so that the two connecting plate bodies 2 can approach the two shock absorber towers 202 respectively, so as to facilitate the two connecting plate bodies 2 to be connected to the two shock absorber towers 202 respectively.

[0046] In addition, a first connecting portion 11 is provided on the tie rod body 1, and the first connecting portion 11 is used to be connected to the connecting structure 203, that is, the connection between the tie rod body 1 and the connecting structure 203 can be realized through the first connecting portion 11, and then the connection between the transverse rod 100 and the front upper portion 201 can be realized. At the same time, a second connecting portion 21 is provided on the connecting plate body 2, and the second connecting portion 21 is used to be connected to the shock absorber tower 202, that is, the connection between the connecting plate body 2 and the shock absorber tower 202 can be realized through the second connecting portion 21, and then the connection between the transverse rod 100 and the shock absorber can be realized, and there are at least three second connecting portions 21, that is, the number of second connecting portions 21 can be three, four or more, and then the connecting plate body 2 and the shock absorber tower 202 can be connected at the same time through at least three second connecting portions 21, which can improve the connection reliability between the two, and then improve the connection reliability between the transverse rod 100 and the shock absorber.

[0047] Furthermore, by distributing three of the at least three second connection portions 21 in a triangular shape, the three second connection portions 21 can be spaced apart and distributed, and the three second connection portions 21 are not located on the same straight line. Thus, the connecting plate body 2 and the shock absorber tower 202 can be connected at three positions at the same time through the at least three second connection portions 21, which can improve the connection stability between the two, and thus improve the connection stability between the transverse rod 100 and the shock absorber.

[0048] According to the tie rod 100 of the embodiment of the present invention, by connecting the tie rod 100 to the two shock absorber towers 202 at the same time, and connecting the tie rod 100 to the upper part of the front panel 201 through the connecting structure 203, part of the impact force transmitted to one of the shock absorbers when the vehicle has an offset collision can be transmitted along the tie rod 100 to the other shock absorber. At the same time, the impact force transmitted to the tie rod 100 can be transmitted to the upper part of the front panel 201 along the connecting structure 203, which can achieve reliable dissipation of the impact force, effectively reduce the deformation of the shock absorber, and improve the overall stability and torsional stiffness of the vehicle. In addition, three of the at least three second connecting parts 21 used to connect the connecting plate body 2 and the shock absorber tower 202 are distributed in a triangular shape, which can improve the connection reliability and connection stability between the tie rod 100 and the shock absorber tower 202, and thereby improve the reliability of the impact force being transmitted from one shock absorber to the other shock absorber along the tie rod 100.

[0049] In some embodiments, there are three second connection parts 21, namely an inner connection part 211 and two outer connection parts 212; wherein the two outer connection parts 212 are spaced apart along the longitudinal direction of the vehicle, and the inner connection part 211 is located on the inner side of the two outer connection parts 212 to form a triangular distribution with the two outer connection parts 212.

[0050] Specifically, the second connection part 21 is used to realize the connection between the connecting plate body 2 and the shock absorber tower 202. There are three second connection parts 21, that is, the connecting plate body 2 and the shock absorber tower 202 can be connected at the same time through the three second connection parts 21, which can improve the connection reliability between the two, and the three second connection parts 21 are respectively an inner connection part 211 and two outer connection parts 212, wherein the two outer connection parts 212 are spaced apart and distributed along the longitudinal direction of the vehicle, and the inner connection part 211 is located on the inner side of the two outer connection parts 212 to form a triangular distribution with the two outer connection parts 212, that is, the three second connection parts 21 can be spaced apart and distributed, and then the connecting plate body 2 and the shock absorber tower 202 can be connected at three positions at the same time through the three second connection parts 21, and the stability principle of the triangle can be used to improve the connection stability between the two.

[0051] It should be noted that the two outer connection portions 212 are spaced apart and distributed along the longitudinal direction of the vehicle. The longitudinal direction of the vehicle here may be the longitudinal direction of the vehicle or a direction with a small angle to the longitudinal direction of the vehicle.

[0052] In some embodiments, the inner connection portion 211 is disposed opposite the rod body 1 along the length of the rod body 1 ; and / or the outer connection portion 212 is disposed staggered with the rod body 1 along the length of the rod body 1 .

[0053] Specifically, the two shock absorber towers 202 are arranged at the same height along the longitudinal direction of the vehicle. By connecting the transverse rod 100 between the two shock absorber towers 202, the transverse rod 100 can be constructed to extend along the transverse direction of the vehicle, and the tie rod body 1 can be extended along the transverse direction of the vehicle. In this way, the length direction of the tie rod body 1 is along the transverse direction of the vehicle. Along the length direction of the tie rod body 1, the inner connection part 211 is distributed opposite to the tie rod body 1, that is, the inner connection part 211 is located in the extension direction of the tie rod body 1, and along the length direction of the tie rod body 1, the outer connection part 212 is staggered with the tie rod body 1, that is, the outer connection part 212 and the inner connection part 211 can be staggered, and then the two outer connection parts 212 can be spaced apart from the inner connection part 211, so that the connecting plate body 2 and the shock absorber tower 202 can be connected at three positions at the same time through the inner connection part 211 and the two outer connection parts 212, which can improve the connection stability between the two, and thus improve the connection stability between the transverse rod 100 and the shock absorber.

[0054] In some embodiments, the inner connection portion 211 and the two outer connection portions 212 have the same spacing, and the inner connection portion 211 and the two outer connection portions 212 are distributed in an isosceles triangle.

[0055] Specifically, the inner connection part 211 and the two outer connection parts 212 are spaced apart and distributed, and the spacing between the inner connection part 211 and the two outer connection parts 212 is constructed to be the same, so that the distance between the two outer connection parts 212 and the inner connection part 211 can be equal, and the two outer connection parts 212 are spaced apart and distributed along the longitudinal direction of the vehicle, so that the inner connection part 211 and the two outer connection parts 212 can be distributed in an isosceles triangle. Therefore, when the connecting plate body 2 is connected to the shock absorber tower 202 through the inner connection part 211 and the two outer connection parts 212, the load can be jointly distributed at the inner connection part 211 and the two outer connection parts 212 to avoid stress concentration and improve the connection stability between the connecting plate body 2 and the shock absorber tower 202.

[0056] In some embodiments, the connecting plate body 2 is formed with an avoidance recess 22 between the two outer connection parts 212 . The avoidance recess 22 is used to avoid the third connection piece connecting the shock absorber tower 202 and the shock absorber.

[0057] Specifically, the shock absorber tower 202 is connected to the shock absorber, and the shock absorber tower 202 can be connected to the shock absorber through a third connecting member. At the same time, the shock absorber tower 202 is connected to the connecting plate body 2, that is, the shock absorber tower 202 is connected to the shock absorber and the connecting plate body 2 respectively. An avoidance recess 22 is formed on the connecting plate body 2. The avoidance recess 22 is constructed to be recessed from the edge of the connecting plate body 2 toward the inside to avoid the third connecting member, providing sufficient installation space for the third connecting member, so as to achieve the third connecting member. The reliable installation can achieve a reliable connection between the shock absorber tower 202 and the shock absorber, and the avoidance recess 22 is formed between the two external connection parts 212 so that the avoidance recess 22 can be spaced apart from the two external connection parts 212 to avoid the avoidance recess 22 from interfering with any of the external connection parts 212, resulting in an inability to connect the connecting plate body 2 to the shock absorber tower 202 through the external connection parts 212 or a reduction in the reliability of the connection between the connecting plate body 2 and the shock absorber tower 202. The third connecting member can be a bolt.

[0058] In some embodiments, the second connection portion 21 is configured as a second connection hole, and the second connection hole is used to penetrate a second connection member 213 connected to the shock absorber tower 202 , so that the connection plate body 2 is detachably connected to the shock absorber tower 202 .

[0059] Specifically, the connecting plate body 2 is provided with a second connecting portion 21, which is used to connect to the shock absorber tower 202. The connecting plate body 2 and the shock absorber tower 202 can be connected through the second connecting portion 21. The second connecting portion 21 is constructed as a second connecting hole. The second connecting hole is used to penetrate the second connecting member 213 connected to the shock absorber tower 202. The second connecting member 213 can be penetrated into the shock absorber tower 202 to connect the second connecting member 213 to the shock absorber tower 202. The second connecting member 213 is constructed as a bolt, and a threaded hole is formed on the shock absorber tower 202, so that the connection between the second connecting member 213 and the shock absorber tower 202 is achieved through the cooperation between the bolt and the threaded hole, and the second connecting member 213 is passed through the second connecting hole to connect the second connecting member 213 to the connecting plate body 2, so that the second connecting member 213 can be connected to the connecting plate body 2 and the shock absorber tower 202 at the same time, thereby realizing the connection between the connecting plate body 2 and the shock absorber tower 202.

[0060] In addition, the connecting plate body 2 is connected to the shock absorber tower 202 through the second connecting member 213, so that the connecting plate body 2 and the shock absorber tower 202 are detachably connected, which makes it easy to connect or separate the connecting plate body 2 and the shock absorber tower 202, and also makes it easy to install or remove the transverse rod 100. When the transverse rod 100 is damaged and fails, the damaged transverse rod 100 can be removed and a new transverse rod 100 can be installed, which can help reduce maintenance costs.

[0061] In some embodiments, the second connection hole is configured as a through hole, and the inner diameter of the second connection hole is larger than the outer diameter of the second connection member 213 , and the second connection member 213 is loosely matched with the inner wall of the second connection hole.

[0062] Specifically, the second connecting hole is used to penetrate the second connecting member 213, so that the second connecting member 213 can connect the connecting plate body 2 with the shock absorber tower 202, and the second connecting hole is constructed as a through hole, that is, when the second connecting member 213 is penetrated into the second connecting hole, the second connecting member 213 only passes through the second connecting hole, but is not connected and fixed to the second connecting hole, which can simplify the installation steps, and the inner diameter of the second connecting hole is constructed to be larger than the outer diameter of the second connecting member 213, so that when the second connecting member 213 is penetrated into the second connecting hole, the second connecting member 213 can be inserted into the second connecting hole. When the second connecting member 213 is loosely matched with the inner wall of the second connecting hole, the second connecting hole can provide a certain range of movement for the second connecting member 213 to ensure the assembly tolerance. Therefore, when the connecting plate body 2 and the shock absorber tower 202 are connected through the three second connecting parts 21, each second connecting member 213 can be movable in the corresponding second connecting hole to ensure a reliable connection between the second connecting member 213 and the shock absorber tower 202, thereby ensuring a reliable connection between the connecting plate body 2 and the shock absorber tower 202.

[0063] For example, the second connecting member 213 can be constructed as an M8 bolt with a performance grade of 8.8, and the inner diameter of the second connecting hole can be constructed as 14 mm, 14.5 mm or 15 mm, etc., so that when the connecting plate body 2 is connected to the shock absorber tower 202 through the second connecting member 213, the second connecting member 213 can be passed through the second connecting hole first, and then the position of the second connecting member 213 in the second connecting hole can be moved to connect the second connecting member 213 to the shock absorber tower 202, and then the connecting plate body 2 can be connected to the shock absorber tower 202 through the second connecting member 213.

[0064] In some embodiments, the connecting plate body 2 is further provided with a connecting groove 23 . The connecting groove 23 is provided around the second connecting hole, and at least a portion of the second connecting member 213 is located in the connecting groove 23 .

[0065] Specifically, the second connecting hole is used to pass the second connecting member 213 to achieve the connection between the connecting plate body 2 and the shock absorber tower 202. The connecting groove 23 is arranged around the second connecting hole, and the second connecting hole can be arranged in the connecting groove 23, so that the connecting groove 23 can provide a clear installation guide for the second connecting member 213, thereby improving assembly efficiency. Moreover, the connecting groove 23 is constructed to be recessed downward from the upper surface of the connecting plate body 2, so that when the second connecting member 213 is passed through the second connecting hole, at least part of the second connecting member 213 can be located in the connecting groove 23, so as to avoid the second connecting member 213 protruding from the upper surface of the connecting plate body 2, reduce the risk of loosening caused by external impact, and improve the reliability of connecting the connecting plate body 2 and the shock absorber tower 202 through the second connecting member 213.

[0066] In some embodiments, a reinforcing rib 231 is provided in the connecting groove 23 ; wherein the reinforcing rib 231 is configured to extend radially along the connecting groove 23 , and / or there are multiple reinforcing ribs 231 , and the multiple reinforcing ribs 231 are spaced apart and distributed circumferentially of the connecting groove 23 .

[0067] Specifically, the connecting plate body 2 is provided with a connecting groove 23, and the connecting groove 23 is constructed to be recessed downward from the upper surface of the connecting plate body 2, that is, the thickness of the connecting plate body 2 at the connecting groove 23 is relatively small, and the structural strength is relatively low. A reinforcing rib 231 is provided in the connecting groove 23. The reinforcing rib 231 can be used to improve the structural strength at the connecting groove 23, thereby improving the reliability of connecting the connecting plate body 2 with the shock absorber tower 202 through the second connecting member 213, and the reinforcing rib 231 is constructed to extend radially along the connecting groove 23, so that the setting length of the reinforcing rib 231 can be increased, so that the structural strength of the connecting groove 23 can be reliably enhanced by the reinforcing rib 231.

[0068] In addition, there are multiple reinforcing ribs 231, that is, the number of reinforcing ribs 231 can be two, three or more, and then the structural strength of the connecting groove 23 can be jointly improved by multiple reinforcing ribs 231, which can improve the reliability of enhancing the structural strength of the connecting groove 23, and the multiple reinforcing ribs 231 are spaced apart and distributed in the circumferential direction of the connecting groove 23, that is, the multiple reinforcing ribs 231 can be distributed in sequence along the circumference of the connecting groove 23, so that the multiple reinforcing ribs 231 can simultaneously enhance the structural strength of the connecting groove 23 at multiple positions, which can improve the stability of enhancing the structural strength of the connecting groove 23.

[0069] In some embodiments, the pull rod body 1 is formed by extrusion of aluminum; and / or the connecting plate body 2 is constructed as a cast aluminum part.

[0070] Specifically, the tie rod body 1 is extruded from aluminum, that is, the tie rod body 1 can be made of aluminum, which can reduce the weight of the tie rod body 1, and thus reduce the overall weight of the transverse tie rod 100, meeting the lightweight requirements of the vehicle, and the tie rod body 1 is constructed as a long strip extending along the transverse direction of the vehicle. The extrusion molding process can facilitate the processing of the tie rod body 1, and can make the tie rod body 1 have higher strength and better toughness, which is beneficial to improving the reliability of the operation of the tie rod body 1, and the connecting plate body 2 is a cast aluminum part, that is, the connecting plate body 2 can be made of aluminum, which can reduce the weight of the connecting plate body 2, and thus reduce the overall weight of the transverse tie rod 100, meeting the lightweight requirements of the vehicle, and the connecting plate body 2 is provided with a connecting groove 23, a second connecting part 21 and an avoidance recess 22, etc., and the structure is relatively complex. The cast aluminum process can facilitate the processing of the connecting plate body 2, and can make the connecting plate body 2 have higher hardness, which is beneficial to improving the reliability of the operation of the connecting plate body 2.

[0071] Therefore, the tie rod body 1 and the connecting plate body 2 can be made using different processes, so that the transverse tie rod 100 can be a three-section structure, which can reduce processing difficulty and manufacturing cost, and make the transverse tie rod 100 less likely to tear or deform when subjected to force.

[0072] Among them, it should be noted that in actual design, the thickness of the connecting plate body 2 can be constructed to be greater than 7 mm, such as the thickness of the connecting plate body 2 can be constructed to be 8 mm, 8.5 mm or 9 mm, etc., so as to improve the structural strength and working reliability of the connecting plate body 2, and it can be beneficial to improve the dynamic stiffness. Moreover, the straightness of the pull rod body 1 can ensure that it is not easily bent when subjected to force in the Y direction, further improving its working reliability.

[0073] In some embodiments, the pull rod body 1 is connected to the connecting plate body 2 by welding.

[0074] Specifically, the tie rod body 1 and the connecting plate body 2 are made of aluminum through different production processes. The tie rod body 1 and the connecting plate body 2 can be connected by welding to make the transverse tie rod 100 a whole, which can improve the overall structural strength and working reliability of the transverse tie rod 100. The connection by welding can improve the connection strength and connection reliability between the two, thereby improving the working reliability of the transverse tie rod 100.

[0075] Among them, it should be noted that the welding method can be MIG welding. MIG welding (metal inert gas shielded welding) is an efficient and high-quality metal welding method with high welding quality and flexibility, and high welding speed, which can improve production efficiency.

[0076] In some embodiments, the first connecting portion 11 is constructed as a first connecting hole, which is used to pass through a first connecting member 111 connected to the connecting structure 203; and / or, there are multiple first connecting portions 11, and the multiple first connecting portions 11 are distributed in sequence along the length direction of the pull rod body 1.

[0077] Specifically, a first connecting portion 11 is provided on the pull rod body 1, and the first connecting portion 11 is used to be connected to the connecting structure 203, that is, the pull rod body 1 can be connected to the connecting structure 203 through the first connecting portion 11, and the first connecting portion 11 is constructed as a first connecting hole, and the first connecting hole is used to pass through the first connecting member 111 connected to the connecting structure 203, that is, the first connecting member 111 can be passed through the connecting structure 203 to connect the first connecting member 111 to the connecting structure 203, and the first connecting member 111 can be passed through the first connecting hole to connect the first connecting member 111 to the pull rod body 1, so that the first connecting member 111 can be connected to the connecting structure 203 and the pull rod body 1 at the same time, thereby realizing the connection between the pull rod body 1 and the connecting structure 203.

[0078] Furthermore, there are multiple first connection parts 11, that is, the number of first connection parts 11 can be two, three or more, that is, the number of first connection members 111 is multiple, and the multiple first connection members 111 are matched with the multiple first connection parts 11 one by one, and then the pull rod body 1 and the connection structure 203 can be connected at the same time by the multiple first connection members 111, which can improve the connection reliability between the two, and the multiple first connection parts 11 are distributed in sequence along the length direction of the pull rod body 1, that is, the multiple first connection members 111 can be spaced apart along the length direction of the pull rod body 1, so that the multiple first connection members 111 can connect the pull rod body 1 and the connection structure 203 at multiple positions at the same time, which can improve the connection stability between the two.

[0079] In some embodiments, the plurality of first connection portions 11 are arranged opposite each other along the length direction of the pull rod body 1 .

[0080] Specifically, multiple first connection parts 11 are distributed in sequence along the length direction of the pull rod body 1, and the multiple first connection parts 11 are arranged opposite each other along the length direction of the pull rod body 1, so that the multiple first connection parts 11 are located on the same straight line, that is, each first connection part 11 is on the same straight line with the other first connection parts 11, which can simplify the processing and assembly steps, improve processing efficiency, optimize space utilization, avoid stress concentration, and improve the connection stability between the pull rod body 1 and the connecting structure 203.

[0081] In such Figure 1-Figure 2 In the embodiment shown, there are four first connection parts 11, and the four first connection parts 11 are arranged opposite each other and spaced apart along the length direction of the pull rod body 1. The pull rod body 1 and the connection structure 203 can be connected at four positions at the same time through the four first connection parts 11, which can improve the connection reliability and stability between the two.

[0082] In some embodiments, the tie rod body 1 is provided with a plurality of spaced-apart mounting points 12 , and the plurality of mounting points 12 are used to connect to the cowl decoration component.

[0083] Specifically, the tie rod body 1 is constructed to extend laterally along the vehicle, and a mounting point 12 is provided on the tie rod body 1. The mounting point 12 is used to connect the front panel decoration, that is, the tie rod body 1 can be connected to the front panel decoration through the mounting point 12 to achieve fixation of the front panel decoration, and can help improve the stability of the overall structure, and the mounting point 12 is set to be multiple, that is, the number of mounting points 12 can be two, three or more, and then the tie rod body 1 can be connected to the front panel decoration through multiple mounting points 12 at the same time, which can improve the connection reliability between the tie rod body 1 and the front panel decoration, and, moreover, the multiple mounting points 12 are spaced apart and distributed, so that the tie rod body 1 can be connected to the front panel decoration at multiple positions at the same time through multiple mounting points 12, which can improve the connection stability between the two.

[0084] It should be noted that the pull rod body 1 is made of aluminum, and the mounting point 12 can be easily set at any position thereon, which increases the degree of design freedom.

[0085] For example, Figure 1-Figure 2 As shown, there are five mounting points 12 , and the five mounting points 12 are spaced apart and distributed. The pull rod body 1 can be connected to the front panel decoration at five positions at the same time through the five mounting points 12 , which can improve the connection reliability and stability between the two.

[0086] The present invention also provides a front nacelle 200 .

[0087] According to an embodiment of the present invention, the front nacelle 200 includes a front upper portion 201, a transverse tie rod 100 of any one of the above-mentioned embodiments, and two shock absorber towers 202. The front upper portion 201 is spaced apart from the tie rod body 1 in the longitudinal direction of the vehicle and is connected by a connecting structure 203. The connecting plate body 2 is connected to the shock absorber towers 202.

[0088] Specifically, the tie rod 100 includes a tie rod body 1 and two connecting plate bodies 2, and the two connecting plate bodies 2 are respectively connected to the two ends of the tie rod body 1, so that the tie rod 100 can be a whole, which can improve the overall structural strength and working reliability of the tie rod 100. The two connecting plate bodies 2 are respectively connected to the two shock absorber towers 202 one by one, so that the tie rod 100 can be connected between the two shock absorbers, so that when the vehicle has an offset collision, the impact force transmitted to one of the shock absorbers can be transmitted to the other shock absorber along the tie rod 100 to dissipate the impact force, and the tie rod body 1 is connected to the upper part of the front panel 201 through the connecting structure 203, so that part of the impact force transmitted to the tie rod 100 can be further transmitted from the tie rod body 1 to the upper part of the front panel 201 through the connecting structure 203, which can further dissipate the impact force, effectively reduce the deformation of the shock absorber, and improve the overall stability and torsional stiffness of the vehicle.

[0089] Among them, the front panel upper part 201 and the tie rod main body 1 are spaced apart in the longitudinal direction of the vehicle, that is, the front panel upper part 201 and the tie rod main body 1 are spaced apart and distributed along the longitudinal direction of the vehicle, and the front panel upper part 201 is located on the rear side of the tie rod main body 1, so that the impact force on the tie rod main body 1 can be transmitted backward to the front panel upper part 201 through the connecting structure 203, and then transmitted to the frame, so as to achieve reliable dissipation of the impact force.

[0090] In some embodiments, the shock absorber tower 202 is provided with at least three third connection parts 2021 , and the third connection parts 2021 are used to be connected to the shock absorber through a third connection piece, and the at least three third connection parts 2021 are distributed in a triangle.

[0091] Specifically, the shock absorber tower 202 is connected to the shock absorber, and a third connecting portion 2021 is provided on the shock absorber tower 202. The third connecting portion 2021 is used to be connected to the shock absorber through a third connecting member. Figure 3 As shown, the third connection part 2021 can be constructed as a third connection hole, and the third connection member can be simultaneously inserted into the third connection hole and the shock absorber to connect the shock absorber tower 202 to the shock absorber through the third connection member. Moreover, there are at least three third connection parts 2021, that is, the number of third connection parts 2021 can be three, four or more, that is, the number of third connection members is at least three, and at least three third connection members are matched with at least three third connection parts 2021 in a one-to-one correspondence, and then the shock absorber tower 202 and the shock absorber can be connected at the same time through at least three third connection members, which can improve the connection reliability between the two.

[0092] Moreover, at least three third connection parts 2021 are distributed in a triangular shape, that is, at least three third connection parts 2021 are spaced apart and distributed, and at least three third connection parts 2021 are not located on the same straight line, and thus the shock absorber tower 202 can be connected to the shock absorber at three positions at the same time through at least three third connection parts 2021, which can improve the connection stability between the two.

[0093] In some embodiments, there are three second connection portions 21 and three third connection portions 2021 , and the three second connection portions 21 and the three third connection portions 2021 are distributed in a one-to-one correspondence along the transverse direction of the vehicle.

[0094] Specifically, the second connection part 21 is used to realize the connection between the connecting plate body 2 and the shock absorber tower 202. By setting the second connection part 21 to three, the connecting plate body 2 and the shock absorber tower 202 can be connected at the same time through the three second connection parts 21, which can improve the connection reliability between the connecting plate body 2 and the shock absorber tower 202. At the same time, the third connection part 2021 is used to realize the connection between the shock absorber tower 202 and the shock absorber. By setting the third connection part 2021 to three, the shock absorber tower 202 and the shock absorber can be connected at the same time through the three third connection parts 2021, which can improve the connection reliability between the shock absorber tower 202 and the shock absorber.

[0095] Moreover, in the transverse direction of the vehicle, the three second connection parts 21 and the three third connection parts 2021 are distributed one-to-one, that is, the three third connection parts 2021 are spaced apart from the three second connection parts 21 to avoid interference between the third connection parts 2021 and the second connection parts 21, resulting in the inability to connect the shock absorber tower 202 to the connecting plate body 2 and the shock absorber respectively, or resulting in reduced connection reliability between the shock absorber tower 202 and the connecting plate body 2 or the shock absorber.

[0096] It should be noted that, Figure 3 As shown, the three second connecting portions 21 are located on the inner side of the three third connecting portions 2021, so that the tie rod 100 can be connected to the inner side of the shock absorber tower 202, and the shock absorber can be connected to the outer side of the shock absorber tower 202, thereby reducing the setting length of the tie rod 100, reducing the setting cost, and reducing the single-side length of the tie rod 100 by at least 115 mm.

[0097] In addition, a guide hole 2022 is also provided on the shock absorber tower 202. The guide hole 2022 is used to guide the installation tooling, and the three third connecting parts 2021 are distributed around the guide hole 2022, so that the third connecting part can be passed through the third connecting part 2021 through the installation tooling to realize the connection between the shock absorber tower 202 and the shock absorber.

[0098] The present invention also provides a vehicle.

[0099] A vehicle according to an embodiment of the present invention includes the front engine compartment 200 according to any of the aforementioned embodiments. By providing the front engine compartment 200, in the event of an offset collision, the impact force transmitted to one shock absorber can be simultaneously transmitted to the other shock absorber and the front upper portion 201. This reliably dissipates the impact force, effectively reduces shock absorber deformation, and improves the overall stability and torsional rigidity of the vehicle.
