It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] like Figure 1 As shown, an embodiment of the present invention provides a chassis guard plate assembly, including a first guard plate assembly 1 and a second guard plate assembly 7. The first guard plate assembly 1 includes a first guard plate and a first bracket assembly installed on both sides of the first guard plate along a first horizontal direction. The first bracket assembly includes two first transition brackets 4 and a second transition bracket 5. The first transition bracket 4 includes a fixing part 41 and a connecting part 42 connected to the fixing part 41. The fixing part 41 is fixed to the first guard plate, and the second transition bracket 5 is fixed to the first guard plate. The second transition bracket 5 is sandwiched between the two first transition brackets 4 along a second horizontal direction. The second transition bracket 5 is fixedly connected to the connecting part 42 of the adjacent first transition bracket 4. The connecting part 42 is used to connect the longitudinal beam of the vehicle frame. The first horizontal direction is perpendicular to the second horizontal direction.
[0034] By setting a first transition bracket 4 and a second transition bracket 5 on both sides of the first guard plate along the first horizontal direction, and the second transition bracket 5 sandwiched between the two first transition brackets 4 along the second horizontal direction, the first transition bracket 4 is used to connect the longitudinal beam of the vehicle frame. The second transition bracket 5 provides lateral support force to the two adjacent first transition brackets 4, which increases the support area of the first transition bracket 4, improves the rigidity of the first transition bracket 4, and effectively prevents the first transition bracket 4 from deforming when subjected to impact or compression, thereby improving the protective effect of the chassis guard plate and reducing damage to other parts of the vehicle.
[0035] For example, the second transition bracket 5 adopts a U-shaped structure. Specifically, the central structure of the second transition bracket 5 is fixed to the first protective plate, and the two side structures connected to the central structure are respectively fixedly connected to the connecting portion 42 of the first transition bracket 4. The two side structures support the connecting portion 42 of the first transition bracket 4 to improve the overall rigidity of the first transition bracket 4. In other embodiments, the second transition bracket 5 may also adopt a V-shaped structure.
[0036] Furthermore, the first guard plate assembly 1 also includes a first reinforcing member 6, one end of which is connected to the fixing part 41 and the other end of which is connected to the connecting part 42. Specifically, the first reinforcing member 6 adopts a diagonal brace structure.
[0037] By providing a first reinforcing member 6 between the fixing part 41 and the connecting part 42, a stable triangular force-bearing system can be formed. The first reinforcing member 6 can provide support for the connecting part 42, which can enhance the overall stability and rigidity of the first transition bracket 4. Moreover, the first reinforcing member 6 and the second transition bracket 5 are located on both sides of the connecting part in the second horizontal direction. The first reinforcing member 6 and the second transition bracket 5 can further improve the rigidity of the first transition bracket 4, ensuring that it does not deform under impact or compression, thereby improving the protective effect of the chassis guard plate.
[0038] In other embodiments, one end of the first reinforcing member 6 may abut against the fixing part 41, and the other end may abut against the connecting part 42. Specifically, both the fixing part 41 and the connecting part 42 are provided with protrusions, and both ends of the first reinforcing member 6 abut against the protrusions on the fixing part 41 and the connecting part 42, respectively.
[0039] Furthermore, the fixing part 41 of the first transition bracket 4 is detachably connected to the first guard plate. Specifically, the fixing part 41 is bolted to the first guard plate, facilitating disassembly, replacement, and maintenance.
[0040] Similarly, the second transition bracket 5 is detachably connected to the first protective plate. Specifically, the second transition bracket 5 is bolted to the first protective plate, facilitating disassembly, replacement, and maintenance.
[0041] Furthermore, the chassis guard plate assembly also includes a second guard plate assembly 7, which includes a second guard plate and a third transition bracket 8 mounted on both sides of the second guard plate along the first horizontal direction. The third transition bracket 8 is used to connect the battery bracket.
[0042] The second protective plate assembly 7 is connected to the battery bracket by the third transition bracket 8, which can protect the battery bracket and prevent mud, rain, ice and snow from corroding the battery and reducing its service life.
[0043] like Figure 1As shown, there are two second protective plate assemblies 7, which are set according to the actual distribution of the battery brackets to ensure comprehensive protection of the battery brackets and batteries.
[0044] Furthermore, the third transition bracket 8 is detachably connected to the second guard plate. Specifically, the third transition bracket 8 is bolted to the second guard plate, facilitating disassembly, replacement, and maintenance.
[0045] Furthermore, the second guard plate assembly 7 also includes a second reinforcing member 10, one end of which is connected to the second guard plate and the other end of which is connected to the third transition bracket 8. Specifically, the second reinforcing member 10 adopts a diagonal brace structure.
[0046] By setting a second reinforcing member 10 between the second guard plate and the third transition bracket 8, a stable triangular force system can be formed. The second reinforcing member 10 can provide support for the third transition bracket 8, enhance the overall stability and rigidity of the third transition bracket 8, and ensure that it does not deform under impact or compression, thereby improving the protective effect of the chassis guard plate.
[0047] In other embodiments, one end of the second reinforcing member 10 may abut against the second protective plate, and the other end may abut against the third transition bracket 8.
[0048] Furthermore, the first guard plate has grooves at both ends along the first horizontal direction that extend through the second horizontal direction, the fixing part 41 is fixed to the inner wall of the groove, and the second transition bracket 5 is fixed to the inner wall of the groove.
[0049] A groove is provided in the first guard plate, and the fixing part 41 and the second transition bracket 5 are fixed to the inner wall of the groove. This can reduce the occupation of structural space in the thickness direction of the first guard plate. At the same time, the side wall of the groove plays a limiting role for the fixing part 41 and the second transition bracket 5, which can prevent the fixing part 41 and the second transition bracket 5 from shifting.
[0050] Similarly, the second guard plate has grooves at both ends along the first horizontal direction that extend through the second horizontal direction, and the third transition bracket 8 is fixed to the inner wall of the groove, which can reduce the occupation of structural space in the thickness direction of the second guard plate.
[0051] Furthermore, a connector 9 is fixedly provided on the inner wall of the groove of the second guard plate, and the third transition bracket 8 is fixedly connected to the connector 9. Specifically, the connector 9 is connected to the inner wall of the groove of the second guard plate by bolts. This arrangement facilitates the fixed connection of the third transition bracket 8 to the second guard plate.
[0052] Furthermore, the first protective plate includes multiple protective plates 2, which are distributed sequentially along a second horizontal direction. A frame 3 is provided on both sides of the multiple protective plates 2 along a first horizontal direction, and the multiple protective plates 2 are fixedly connected to the frame 3. Specifically, the multiple protective plates 2 are welded and fixed to the frame 3.
[0053] By dividing the first protective plate into multiple individual protective plates 2 and fixing them together, on the one hand, when a collision or compression occurs, the impact force is dispersed to multiple protective plates 2 through the frame 3, which can effectively prevent the first protective plate from deforming as a whole; on the other hand, when an individual protective plate 2 is damaged by collision or corrosion, only the damaged part needs to be replaced, without disassembling the whole, which can greatly reduce maintenance time and material costs.
[0054] Similarly, the second guard plate includes multiple guard plates 2, which are distributed sequentially along the second horizontal direction. The multiple guard plates 2 are provided with a frame 3 on both sides along the first horizontal direction, and the multiple guard plates 2 are fixedly connected to the frame 3.
[0055] Optionally, the frame 3 is disposed on one side of the inner wall of the groove to increase the contact area between the frame 3 and each guard plate 2, which facilitates welding and fixing.
[0056] Furthermore, each guard plate 2 has a bent portion on both sides along the second horizontal direction. Specifically, the bent portion adopts a U-shaped bent structure. This arrangement increases the contact area between the bent portion and the frame 3, making the welding more stable. At the same time, the bent portion also acts as a reinforcing rib, which can improve the overall rigidity of the first and second guard plates and prevent deformation due to collision or compression.
[0057] Furthermore, each skid plate 2 is equipped with drainage holes. This design facilitates water drainage, effectively preventing water accumulation and reducing corrosion and damage to vehicle structural components.
[0058] An embodiment of this utility model provides a vehicle, including a frame and the aforementioned chassis guard assembly, wherein the frame is connected to a first transition bracket 4.
[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
