Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly relates to a wheelhouse reinforcement and a vehicle. Background Art

[0002] In the prior art, the wheelhouse reinforcement of a vehicle is two split structural members. One wheelhouse reinforcement connects the first front wheelhouse of the vehicle and the lower mounting plate of the front partition, and the other wheelhouse reinforcement connects the second front wheelhouse of the vehicle and the lower mounting plate of the front partition. The structural strength of this connection structure mainly depends on the structural strength of the lower mounting plate of the front partition. As more and more functional modules are required to be arranged in the connection structure of the front wheelhouse, the wheelhouse connection member and the lower mounting plate of the front partition in the vehicle, the prior art lower mounting plate of the front partition is difficult to meet the required structural strength, resulting in a relatively low structural strength of the connection structure of the wheelhouse reinforcement, the front wheelhouse and the lower mounting plate of the front partition. Summary of the Utility Model

[0003] In view of this, the present application provides a wheelhouse reinforcement and a vehicle, which can improve the structural strength of the connection structure of the wheelhouse reinforcement, the front wheelhouse and the lower mounting plate of the front partition.

The reinforcement portion has a first end and a second end oppositely arranged along its own length direction. The first wheelhouse connection portion is connected to the first end, and the second wheelhouse connection portion is connected to the second end. Since the wheelhouse reinforcement is an integrally formed structural member, that is, the first wheelhouse connection portion, the reinforcement portion, and the second wheelhouse connection portion are integrally formed, the structural strength of the wheelhouse reinforcement is higher, making the structural strength of the connection structure of the wheelhouse reinforcement, the first front wheelhouse, the second front wheelhouse, and the lower mounting plate of the front partition higher. Further, the reinforcement portion includes a connected reinforcement body and a first flanging structure. That is to say, the first flanging structure is bent relative to the reinforcement body. This setting can further improve the bending structural strength of the reinforcement portion, thereby improving the bending structural strength of the connection structure of the wheelhouse reinforcement, the first front wheelhouse, the second front wheelhouse, and the lower mounting plate of the front partition. The above setting is also beneficial to improving the NVH performance of the vehicle (an index for measuring the comfort and manufacturing quality of an automobile, mainly including noise, vibration, and harshness). Correspondingly, the driving experience and riding experience of users are better.

[0042] For a better understanding of the technical solution of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0043] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0044] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "the", and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0045] It should be understood that the term "and / or" used herein is only a relational description of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0046] In the drawings of the present application, the direction X represents the longitudinal direction of the vehicle (the direction from the vehicle tail to the vehicle front), the direction Y represents the transverse direction of the vehicle (the direction from one side of the vehicle to the other side), the direction Z represents the height direction of the vehicle (the direction from the vehicle bottom to the vehicle top), and the directions X, Y, and Z are perpendicular to each other in pairs.

[0047] In a first aspect, an embodiment of the present application provides a wheelhouse reinforcement for a vehicle. Please refer to Figure 1 As shown, the wheelhouse reinforcement 1 includes a first wheelhouse connection portion 11, a reinforcement portion 12, and a second wheelhouse connection portion 13. Among them, the first wheelhouse connection portion 11 is used to connect to the first front wheelhouse 2 and the lower front bulkhead mounting plate 4 of the vehicle as shown in Figures 2 - 3 As shown, the reinforcement portion 12 is used to connect to the lower front bulkhead mounting plate 4 as shown in Figures 2 - 3 As shown, the second wheelhouse connection portion 13 is used to connect to the second front wheelhouse 3 and the lower front bulkhead mounting plate 4 of the vehicle as shown in Figures 2 - 3 As shown, the first front wheelhouse 2 is used to cover one of the front wheels of the vehicle, the second front wheelhouse 3 is used to cover the other front wheel of the vehicle, and the lower front bulkhead mounting plate 4 is one of the structural members of the front bulkhead assembly, and the front bulkhead assembly is used to separate the engine compartment and the driver's cab of the vehicle.

[0048] Please refer to Figure 1 As shown, the reinforcement portion 12 has a first end 12a and a second end 12b oppositely arranged along its own length direction (direction Y). The first wheelhouse connection portion 11 is connected to the first end 12a, and the second wheelhouse connection portion 13 is connected to the second end 12b. The reinforcement portion 12 can improve the structural strength of the connection structure of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the lower front bulkhead mounting plate 4.

[0049] Since the wheelhouse reinforcement 1 is an integrally formed structural member, that is, the first wheelhouse connecting portion 11, the reinforcing portion 12, and the second wheelhouse connecting portion 13 are integrally formed, the structural strength of the wheelhouse reinforcement 1 is higher, making the structural strength of the connection structure of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the front bulkhead lower mounting plate 4 higher.

[0050] Furthermore, the reinforcing portion 12 includes a connected reinforcing body 121 and a first flanging structure 122. That is to say, the first flanging structure 122 is bent relative to the reinforcing body 121. This setting can further improve the bending structural strength of the reinforcing portion 12, thereby improving the bending structural strength of the connection structure of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the front bulkhead lower mounting plate 4.

[0051] The above setting is also beneficial to improving the NVH performance of the vehicle (an index for measuring the comfort and manufacturing quality of an automobile, mainly including noise, vibration, and harshness). Correspondingly, the driving experience and riding experience of users are better.

[0052] Among them, the whole of the wheelhouse reinforcement 1 can be formed by stamping a same sheet metal structural member.

[0053] Optionally, please refer to Figure 1 As shown, the first flanging structure 122 includes a reinforcing rib 122a formed by bending, and the extending direction of the reinforcing rib 122a is perpendicular to the length direction (direction Y). The reinforcing rib 122a formed by bending can improve the bending structural strength of the first flanging structure 122 to reduce the possibility of structural problems such as plastic deformation, cracking, or fracture of the first flanging structure 122 when subjected to external forces.

[0054] Among them, the number of the reinforcing ribs 122a is at least two, and at least two reinforcing ribs 122a are arranged at intervals along the length direction (direction Y).

[0055] In addition, since the wheelhouse reinforcement 1 is formed by stamping a sheet metal structural member, the reinforcing rib 122a formed by bending can be regarded as a concave structure in the top view, and the reinforcing rib 122a formed by bending can be regarded as a convex structure in the bottom view.

[0056] Optionally, please refer to Figure 4 As shown, the reinforcing body 121 includes a concave portion 121a formed by bending, and the reinforcing rib 122a extends from the connection of the first flanging structure 122 and the concave portion 121a to the edge of the first flanging structure 122 away from the concave portion 121a. The concave portion 121a formed by bending can improve the bending structural strength of the reinforcing body 121, thereby improving the bending structural strength of the connection structure of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the front bulkhead lower mounting plate 4.

[0057] Among them, since the size of the reinforcing body 121 is relatively large compared to the size of the first flanging structure 122, the size of the recessed portion 121a is also relatively large compared to the volume of the reinforcing rib 122a, so that the bending structural strength of the reinforcing body 121 is within a suitable range.

[0058] In addition, the recessed direction of the recessed portion 121a can be the direction away from the lower mounting plate 4 of the front partition by the reinforcing body 121. Or rather, the recessed portion 121a formed by bending in the top-down view can be regarded as a recessed structure. Since the wheelhouse reinforcement 1 is formed by stamping a sheet metal structural member, the recessed portion 121a formed by bending can be regarded as a convex structure in the bottom-up view.

[0059] Furthermore, the recessed direction of the reinforcing rib 122a and the recessed direction of the recessed portion 121a are both the direction away from the lower mounting plate 4 of the front partition by the reinforcing body 121.

[0060] Optionally, please refer to Figure 1 As shown, the first flanging structure 122 includes an expansion tank mounting portion 122b, and the expansion tank mounting portion 122b is used to mount an expansion tank (one of the parts of the vehicle engine cooling system). In the prior art, the expansion tank mounting portion is arranged on the lower mounting plate of the front partition. Compared with the prior art, in the embodiment, the first flanging structure 122 can share a part of the load for bearing the expansion tank for the lower mounting plate 4 of the front partition. The lower mounting plate 4 of the front partition is not likely to have structural problems due to bearing a large load, that is, the structural reliability degree of the lower mounting plate 4 of the front partition is relatively high. Correspondingly, the structural reliability degrees of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the lower mounting plate 4 of the front partition are relatively high.

[0061] Among them, the expansion tank mounting portion 122b can be any detachable connection structure such as a hole structure, a groove structure, a convex structure, etc.

[0062] Optionally, please refer to Figure 1 As shown, the reinforcing body 121 includes a wiper motor mounting portion 121b and a wiper motor shaft through hole 121c. The wiper motor mounting portion 121b is used to mount a wiper motor, and the wiper motor shaft through hole 121c is used to be penetrated by the wiper motor shaft. In the prior art, the wiper motor mounting portion and the wiper motor shaft through hole are both arranged on the lower mounting plate of the front partition. Compared with the prior art, in the embodiment, the reinforcing body 121 can share a part of the load for bearing the wiper motor for the lower mounting plate 4 of the front partition. The lower mounting plate 4 of the front partition is not likely to have structural problems due to bearing a large load, that is, the structural reliability degree of the lower mounting plate 4 of the front partition is relatively high. Correspondingly, the structural reliability degrees of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the lower mounting plate 4 of the front partition are relatively high.

[0063] Optionally, please refer toFigure 1 As shown, the reinforcing portion 12 further includes a second flanging structure 123. The edge of the reinforcing body 121 away from the first flanging structure 122 is connected to the second flanging structure 123. In other words, the second flanging structure 123 is bent relative to the reinforcing body 121. This setting can further improve the bending structural strength of the reinforcing portion 12, thereby improving the bending structural strength of the connection structure of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the front bulkhead lower mounting plate 4.

[0064] Among them, the second flanging structure 123 may include a reinforcing rib structure or a mounting structure for mounting other vehicle parts.

[0065] Optionally, please refer to Figure 1 As shown, at least one of the reinforcing body 121, the first flanging structure 122, and the second flanging structure 123 is provided with a wire harness mounting portion 124. The wire harness mounting portion 124 is used to mount the wire harness of the vehicle. In the prior art, the wire harness mounting portion is provided on the front bulkhead lower mounting plate. Compared with the prior art, at least one of the reinforcing body 121, the first flanging structure 122, and the second flanging structure 123 in the embodiment can share a part of the load for carrying the wire harness for the front bulkhead lower mounting plate 4. The load that can be borne saved for the front bulkhead lower mounting plate 4 can meet the structural strength requirements of the connection structure of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the front bulkhead lower mounting plate 4. The front bulkhead lower mounting plate 4 is not easily structurally damaged due to bearing a large load, that is, the structural reliability degree of the front bulkhead lower mounting plate 4 is relatively high. Correspondingly, the structural reliability degrees of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3, and the front bulkhead lower mounting plate 4 are relatively high.

[0066] In a second aspect, an embodiment of the present application provides a vehicle. The vehicle includes the wheelhouse reinforcement 1, the first front wheelhouse 2, and the second front wheelhouse 3 described above. Among them, the first front wheelhouse 2 is connected to the first wheelhouse connection portion 11 of the wheelhouse reinforcement 1, and the second front wheelhouse 3 is connected to the second wheelhouse connection portion 13 of the wheelhouse reinforcement 1. Therefore, the vehicle in the embodiment of the present application also includes the technical effects described above.

[0067] Optionally, the vehicle further includes a front bulkhead lower mounting plate 4. The front bulkhead lower mounting plate 4 is connected to the wheelhouse reinforcement 1. The first flanging structure 122 includes a reinforcing rib 122a formed by bending. The reinforcing rib 122a and the front bulkhead lower mounting plate 4 enclose an exhaust passage 6 as shown in Figure 4 As shown, the reinforcing body 121 includes a recessed portion 121a formed by bending. The recessed portion 121a and the front bulkhead lower mounting plate 4 enclose as shown in Figure 4The cavity 7 shown is provided, which is beneficial to enhancing the structural strength of the connection structure of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3 and the front bulkhead lower mounting plate 4. Subsequently, it is beneficial to improving the NVH performance of the vehicle (an indicator for measuring the comfort and manufacturing quality of an automobile, mainly including noise, vibration and harshness). Correspondingly, the driving experience and riding experience of users are better. The exhaust passage 6 communicates with the cavity 7, enabling the cavity 7 to communicate with the external atmosphere, which is beneficial to balancing the air pressure inside the cavity 7 and the external atmospheric pressure, and can reduce the possibility of the recess 121a and the front bulkhead lower mounting plate 4 bearing the additional dynamically changing air pressure difference force, so that the possibility of the recess 121a and the front bulkhead lower mounting plate 4 deforming is relatively low. Secondly, the communication between the exhaust passage 6 and the cavity 7 is also beneficial to allowing the electrocoating liquid to enter the interior of the cavity 7 through the exhaust passage 6 during the painting process, so as to facilitate the formation of a uniform paint film on the inner surface for enclosing and forming the cavity 7.

[0068] Optionally, please refer to Figure 5 As shown, the vehicle further includes a power control unit mounting bracket 5. The power control unit mounting bracket 5 is connected to the wheelhouse reinforcement 1 and is used for mounting the power control unit. In the prior art, the power control unit mounting bracket is mounted on the front bulkhead lower mounting plate. Compared with the prior art, in the embodiment, the wheelhouse reinforcement 1 can share a part of the load of bearing the power control unit mounting bracket 5 and the power control unit for the front bulkhead lower mounting plate 4, and the front bulkhead lower mounting plate 4 is not likely to have structural problems due to bearing a large load, that is, the structural reliability degree of the front bulkhead lower mounting plate 4 is relatively high. Correspondingly, the structural reliability degrees of the wheelhouse reinforcement 1, the first front wheelhouse 2, the second front wheelhouse 3 and the front bulkhead lower mounting plate 4 are relatively high.

[0069] Among them, the power control unit mounting bracket 5 can be mounted on the reinforcement body 121 of the wheelhouse reinforcement 1.

[0070] Since the wheelhouse reinforcement 1 of the vehicle is an integrally formed structural member, secondly, since the reinforcement part 12 of the wheelhouse reinforcement 1 of the vehicle can share the load-bearing for the front bulkhead lower mounting plate 4, there is no need to additionally provide a structural reinforcement plate mounted on the front bulkhead lower mounting plate 4 inside the vehicle. The number of parts required for the vehicle is less, the manufacturing difficulty of the vehicle is lower, and the manufacturing cycle of the vehicle is shorter.
