[0003] In related technologies, the edges of the vehicle skid plate are fixed to complete the installation. This setup results in poor structural rigidity. Utility Model Content

[0004] The embodiments of this utility model provide a vehicle skid plate fixing structure and vehicle, which can improve at least some of the above-mentioned technical problems.

[0005] In a first aspect, embodiments of the present invention provide a vehicle skid plate fixing structure, the vehicle skid plate fixing structure includes a vehicle skid plate, the vehicle skid plate includes a first connecting part and a second connecting part, the first connecting part is located on the periphery of the second connecting part, and the vehicle skid plate is fixed through the first connecting part and the second connecting part.

[0006] In this embodiment, the vehicle skid plate is fixed by the first connecting portion and the second connecting portion. That is, both the periphery and the center of the vehicle skid plate are fixed. Compared to related technologies that only fix the four edges of the vehicle skid plate, this embodiment further fixes the center of the vehicle skid plate, resulting in a better overall fixation effect.

[0007] In one embodiment, the vehicle skid plate fixing structure further includes a battery pack housing, which includes a housing frame and a crossbeam connected to each other. The housing frame forms a mounting cavity and a top opening communicating with the mounting cavity. The crossbeam is installed in the mounting cavity. The vehicle skid plate is located on the side of the battery pack housing opposite to the top opening. The first connecting part is connected to the housing frame, and the second connecting part is connected to the crossbeam.

[0008] In this embodiment, the vehicle skid plate includes a first connecting portion and a second connecting portion. The first connecting portion is located around the second connecting portion and is connected to the box frame, while the second connecting portion is connected to a crossbeam. In other words, the periphery of the vehicle skid plate is connected to the box frame, and the center of the vehicle skid plate is connected to the crossbeam. Compared to related technologies that only fix the four edges of the vehicle skid plate, this embodiment connects the second connecting portion of the vehicle skid plate to the crossbeam, further securing the center of the vehicle skid plate, thus improving the overall fixation of the vehicle skid plate.

[0009] In one embodiment, the housing frame includes a side frame and a bottom guard plate. The side frame is connected to the periphery of the bottom guard plate, and the bottom guard plate and the side frame form the mounting cavity. The crossbeam is connected to the bottom guard plate, and the vehicle guard plate is located on the side of the bottom guard plate opposite to the crossbeam.

[0010] The vehicle's protective plate is installed below the battery to protect it.

[0011] In one embodiment, the vehicle skid plate fixing structure further includes a mounting assembly, which includes a first mounting member and a second mounting member. The first mounting member is fixed to the end of the crossbeam facing the vehicle skid plate, and the second mounting member is connected to both the vehicle skid plate and the first mounting member. Thus, the crossbeam and the vehicle skid plate are connected via the first and second mounting members.

[0012] In one embodiment, the second mounting member includes a first sub-part and a second sub-part connected to each other. The vehicle skid plate has a through hole. The first sub-part abuts against the side of the vehicle skid plate opposite to the crossbeam. The second sub-part passes through the through hole, and the end of the second sub-part opposite to the first sub-part is connected to the first mounting member. The first sub-part can drive a tighter connection between the vehicle skid plate and the crossbeam.

[0013] In one embodiment, the first mounting member includes a first mounting portion, which is embedded in one end of the crossbeam facing the vehicle guard plate. The first mounting member has a first opening, and a second sub-part is connected to the wall of the first opening.

[0014] In one embodiment, the first mounting member includes a first peripheral portion connected to the periphery of the first mounting part, and the first peripheral portion is connected to one end of the crossbeam facing the vehicle guard plate.

[0015] In one embodiment, the vehicle underbody protection plate fixing structure further includes a sealing element, which is sandwiched between the underbody protection plate and the first peripheral portion of the first mounting member. This ensures a seal between the underbody protection plate and the first peripheral portion, thereby preventing external moisture or dirt from entering the battery pack housing.

[0016] In one embodiment, the mounting assembly further includes a third mounting member, which includes a second mounting portion and a second peripheral portion. The second peripheral portion is arranged around the periphery of the second mounting portion and is connected to the wall of the first opening. The second peripheral portion abuts against the side of the bottom guard plate opposite to the crossbeam. Through the cooperation of the first, second, and third mounting members, the vehicle guard plate can be better secured while ensuring a seal between the bottom guard plate and the first peripheral portion, thereby improving the internal sealing of the battery pack housing.

[0017] In one embodiment, the wall of the first opening is recessed with an annular groove at one end near the vehicle skid plate, and the second mounting part is connected to the side wall of the annular groove. By providing the annular groove, the opening space of the first opening is increased, facilitating the installation of the second mounting part. The annular groove at the end of the wall of the first opening near the vehicle skid plate creates a stepped structure on the wall of the first opening, which can support and limit the position of the second mounting part.

[0018] In one embodiment, the vehicle skid plate has a protrusion on the side facing the crossbeam, the protrusion having a through hole, and the protrusion abutting against the second peripheral portion. The protrusion can press tightly against the second peripheral portion, so that the second peripheral portion can press tightly against the first peripheral portion, thereby making the connection between the vehicle skid plate and the crossbeam more secure.

[0019] Secondly, embodiments of this utility model provide a vehicle including the vehicle skid plate fixing structure described above. This vehicle possesses all the beneficial effects of the aforementioned vehicle skid plate fixing structure, which will not be repeated here. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0029] Currently, most vehicle skid plate mounting points are designed on the vehicle frame, around the battery pack mounting points, or on welded brackets on the four sides of the battery pack. In related technologies, the skid plate is only fixed to the frame or battery pack at its four edges, with no fixing point in the center. Because the skid plate has a large area but a small thickness, its structural rigidity is poor, for example, its Z-axis rigidity is poor. Relying solely on the four perimeter fixing points is insufficient to ensure that the skid plate meets the modal requirements.

[0030] Please combine Figure 1 In a first aspect, in the embodiments of this application, a vehicle skid plate fixing structure 1 is provided. The vehicle skid plate fixing structure 1 includes a vehicle skid plate 30. The vehicle skid plate 30 includes a first connecting part 31 and a second connecting part 33. The first connecting part 31 is located around the second connecting part 33. The vehicle skid plate is fixed by the first connecting part 31 and the second connecting part 33.

[0031] In this embodiment, the vehicle skid plate 30 includes a first connecting portion 31 and a second connecting portion 33. The first connecting portion 31 is located around the second connecting portion 33, and the vehicle skid plate is fixed through the first connecting portion 31 and the second connecting portion 33. In some scenarios, the first connecting portion 31 and the second connecting portion 33 can be used to connect to the battery pack housing 10, that is, the vehicle skid plate is fixed to the battery pack housing 10 through the first connecting portion 31 and the second connecting portion 33. Compared with the related technology, which only fixes the four edges of the vehicle skid plate, this embodiment further fixes the middle part of the vehicle skid plate 30, thereby making the overall fixing effect of the vehicle skid plate 30 better. This can both distribute the load of other hanging points and improve the overall modality, so that the vehicle skid plate 30 will not be affected by vibration during vehicle operation, improve vehicle safety or comfort, avoid resonance, control vibration amplitude, and reduce noise and structural risks.

[0032] Please combine Figure 1 The vehicle skid plate fixing structure 1 also includes a battery pack housing 10. The battery pack housing 10 includes a connected housing frame 11 and a crossbeam 13. The housing frame 11 forms a mounting cavity 110 and a top opening 111 communicating with the mounting cavity 110. The crossbeam 13 is installed inside the mounting cavity 110. The vehicle skid plate 30 is located on the side of the battery pack housing 10 opposite to the top opening 111. Please refer to... Figure 4 The vehicle skid plate 30 includes a first connecting part 31 and a second connecting part 33. The first connecting part 31 is located around the second connecting part 33. The first connecting part 31 is connected to the box frame 11, and the second connecting part 33 is connected to the crossbeam 13.

[0033] In this embodiment, the vehicle skid plate 30 includes a first connecting portion 31 and a second connecting portion 33. The first connecting portion 31 is located around the second connecting portion 33 and is connected to the housing frame 11. The second connecting portion 33 is connected to the crossbeam 13. That is, the periphery of the vehicle skid plate 30 is connected to the housing frame 11, and the middle portion of the vehicle skid plate 30 is connected to the crossbeam 13. Compared to related technologies where only the four edges of the vehicle skid plate 30 are fixed to the vehicle frame or battery pack, this embodiment connects the second connecting portion 33 of the vehicle skid plate 30 to the crossbeam 13, further securing the middle portion of the vehicle skid plate 30, thus improving the overall fixation of the vehicle skid plate 30. This not only distributes the load on other suspension points but also improves the overall modal stability, ensuring that the vehicle skid plate 30 does not suffer performance issues due to vibration during vehicle operation, improving vehicle safety or comfort, avoiding resonance, controlling vibration amplitude, and reducing noise and structural risks.

[0034] The crossbeam 13 is installed inside the mounting cavity 110, which can divide the mounting cavity 110 into a first sub-cavity and a second sub-cavity. Both the first sub-cavity and the second sub-cavity can be used to install the battery pack.

[0035] Please combine Figure 1 The box frame 11 includes a side frame 112 and a bottom guard plate 113. The side frame 112 is connected to the periphery of the bottom guard plate 113. The bottom guard plate 113 and the side frame 112 form a mounting cavity 110. The crossbeam 13 is connected to the bottom guard plate 113. The whole vehicle guard plate 30 is located on the side of the bottom guard plate 113 away from the crossbeam 13.

[0036] Once installed in a car, the battery is susceptible to impacts during use, especially when mounted on the car's floor, where it's vulnerable to collisions with road debris. For example, during bumpy rides, the battery can easily collide with stones underneath the car, causing deformation of the battery compartment. A vehicle underbody protection plate installed beneath the battery provides protection.

[0037] Please combine Figure 1 The vehicle skid plate fixing structure 1 also includes a mounting assembly 50, which includes a first mounting member 51 and a second mounting member 53. The first mounting member 51 is fixed to the end of the crossbeam 13 facing the vehicle skid plate 30, and the second mounting member 53 is connected to both the vehicle skid plate 30 and the first mounting member 51. Thus, the crossbeam 13 and the vehicle skid plate 30 are connected by the first mounting member 51 and the second mounting member 53.

[0038] The first mounting component 51 and the second mounting component 53 can be connected by screws.

[0039] Please combine Figure 1 and Figure 5 The second mounting member 53 includes a first sub-part 531 and a second sub-part 533 connected to each other. The vehicle guard plate 30 is provided with a through hole 300. The first sub-part 531 abuts against the side of the vehicle guard plate 30 away from the crossbeam 13. The second sub-part 533 passes through the through hole 300. The end of the second sub-part 533 away from the first sub-part 531 is connected to the first mounting member 51.

[0040] In some examples, the second sub-part 533 is screwed to the first mounting member 51, so that when the first sub-part 531 is rotated, the second sub-part 533 rotates synchronously and is secured to the first mounting member 51. Since the first sub-part 531 abuts against the side of the vehicle guard plate 30 away from the crossbeam 13, the first sub-part 531 can drive the vehicle guard plate 30 to be more tightly connected to the crossbeam 13.

[0041] Please combine Figure 4 and Figure 5The first mounting component 51 includes a first mounting portion 511, which is embedded in the end of the crossbeam 13 facing the vehicle guard plate 30. Please refer to... Figure 1 and Figure 6 The crossbeam 13 has a first end 131 facing away from the vehicle guard plate 30 and a second end 133 facing the vehicle guard plate 30. A first mounting part 511 is embedded in the second end 133. The first mounting member 51 is provided with a first opening 512, and a second sub-part 533 is connected to the wall of the first opening 512.

[0042] The end of the crossbeam 13 facing the bottom cover plate of the battery pack (second end 133) may have a clearance hole for inserting the first mounting part 511 of the first mounting member 51. The first mounting member 51 has a first opening 512, the wall of the first opening 512 may be threaded, and the second sub-part 533 is connected to the wall of the first opening 512, so that the second sub-part 533 is screwed to the first mounting member 51.

[0043] The first opening 512 can be a blind hole.

[0044] Please combine Figure 4 and Figure 5 The first mounting member 51 includes a first peripheral portion 513, which is connected to the periphery of the first mounting portion 511. The first peripheral portion 513 is connected to the end of the crossbeam 13 facing the vehicle guard plate 30. The first peripheral portion 513 and the end of the crossbeam 13 facing the vehicle guard plate 30 can be welded.

[0045] Please combine Figure 2 and Figure 5 The vehicle guard plate fixing structure 1 also includes a seal 70, which is sandwiched between the bottom guard plate 113 and the first peripheral edge 513 of the first mounting member 51. This ensures a seal between the bottom guard plate 113 and the first peripheral edge 513 of the first mounting member 51, thereby preventing external moisture or dirt from entering the battery pack housing 10.

[0046] The seal 70 can be made of silicone foam.

[0047] Please combine Figure 3 , Figure 4 and Figure 5The mounting assembly 50 also includes a third mounting member 55, which includes a second mounting portion 551 and a second peripheral portion 553. The second peripheral portion 553 is arranged around the periphery of the second mounting portion 551. The second mounting portion 551 is connected to the wall of the first opening 512, and the second peripheral portion 553 abuts against the side of the bottom guard plate 113 away from the crossbeam 13. Thus, the third mounting member 55 can be fastened to the first mounting member 51. When the third mounting member 55 is tightened, the second peripheral portion 553 of the third mounting member 55 can abut against the bottom guard plate 113, the seal 70, the first peripheral portion 513, and the crossbeam 13, making the connection between the bottom guard plate 113, the seal 70, the first peripheral portion 513, and the crossbeam 13 tighter, and also allowing the bottom guard plate 113 and the first peripheral portion 513 to clamp the seal 70. In other words, through the cooperation of the first mounting part 51, the second mounting part 53, and the third mounting part 55, it is possible to better fix the vehicle guard plate while ensuring the seal between the bottom guard plate 113 and the first peripheral part 513, thereby making the internal sealing of the battery pack box 10 better.

[0048] The second mounting part 551 and the hole wall of the first opening 512 can be screwed together.

[0049] Please combine Figure 4 and Figure 5 The first opening 512 has an annular groove 5120 recessed at one end of the wall near the vehicle guard plate 30, and the second mounting part 551 is connected to the side wall of the annular groove 5120.

[0050] By providing the annular groove 5120, the opening space of the first opening 512 is increased, facilitating the installation of the second mounting part 551. The annular groove 5120 is recessed at one end of the wall of the first opening 512 near the vehicle guard plate 30, creating a stepped structure on the wall of the first opening 512. This structure supports and limits the second mounting part 551.

[0051] The sidewall of the annular groove 5120 may be threaded, so that the second mounting part 551 is screwed to the sidewall of the annular groove 5120.

[0052] In one example, the first mounting component 51 can be a nut, and the second mounting component 53 can be a bolt. The bolt may have a through hole in the middle, which can be a hexagonal hole.

[0053] Please combine Figure 5 and Figure 6The vehicle skid plate 30 has a protrusion 35 on the side facing the crossbeam 13. The protrusion 35 has a through hole 300 and abuts against the second peripheral portion 553. With this configuration, when the first sub-part 531 is rotated, the first sub-part 531 can drive the vehicle skid plate 30 to move towards the side closer to the crossbeam 13. The protrusion 35 can then press against the second peripheral portion 553, so that the second peripheral portion 553 can press against the first peripheral portion 513, thereby making the connection between the vehicle skid plate 30 and the crossbeam 13 more tight.

[0054] Please combine Figure 7 According to a second aspect of this application, a vehicle 2 is also provided, including the vehicle guard plate fixing structure 1 as described above.

[0055] The vehicle 2 has all the beneficial effects of the above-mentioned vehicle guard plate fixing structure 1, which will not be repeated here.

[0056] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
