[0036] When it comes to the design of the bottom guard plate assembly in the bumper and subframe area, since the bumper is fixed relative to the vehicle and the subframe moves relative to the vehicle during driving, the bottom guard plates in the bumper and subframe areas need to be set separately, resulting in a large number of bottom guard plates with small sizes and scattered distribution, making it difficult to ensure the flatness of the bottom surface of the vehicle, thereby increasing the vehicle's wind resistance and affecting the vehicle's fuel economy and power performance.

[0037] Reference below Figure 1-Figure 6 A bottom guard plate assembly 1 according to an embodiment of the present invention is described.

[0038] like Figure 1-Figure 4 As shown, according to the utility model, the bottom guard plate assembly 1 is used for a vehicle, and the bottom guard plate assembly 1 includes a first guard plate 11 and a second guard plate 12. The first guard plate 11 is formed with a first mounting portion 111, and the first mounting portion 111 is suitable for being connected to a bumper, and the first guard plate 11 is arranged at the bottom of the bumper; the second guard plate 12 is connected to the first guard plate 11 and a second mounting portion 121 is formed on the second guard plate 12, and the second mounting portion 121 is suitable for being connected to a sub-frame, and the second guard plate 12 is arranged at the bottom of the sub-frame; wherein the second mounting portion 121 is constructed as a flexible connector.

[0039] According to the bottom guard plate assembly 1 of the utility model, a first mounting portion 111 is formed on the first guard plate 11, and the first mounting portion 111 is used to connect with the bumper, so that the first guard plate 11 can be set at the bottom of the bumper to provide bottom protection for the bumper. A second mounting portion 121 is formed on the second guard plate 12, and the second mounting portion 121 is used to connect with the subframe, so that the second guard plate 12 can be set at the bottom of the subframe to provide bottom protection for the subframe. The second guard plate 12 is connected to the first guard plate 11 into an integral structure, which enhances the rigidity and stability of the structure, and at the same time can ensure the flatness of the bottom surface of the vehicle, thereby reducing wind resistance and improving the fuel economy and power performance of the vehicle. By constructing the second mounting portion 121 as a flexible connector, the flexible connector can produce elastic deformation to adapt to the movement of the subframe relative to the second guard plate 12 during the driving of the vehicle, ensuring the stability of the connection between the second mounting portion 121 and the subframe, and fully playing the role of shock absorption and buffering.

[0040] Therefore, according to the bottom guard plate assembly 1 of the utility model, the flatness of the bottom surface of the vehicle can be ensured, thereby reducing wind resistance. At the same time, the flexible connecting part can produce elastic deformation to adapt to the movement of the subframe relative to the second guard plate 12 during the driving of the vehicle, ensure the stability of the connection between the second mounting part 121 and the subframe, and fully play a role in shock absorption and buffering.

[0041] According to some embodiments of the present invention, Figure 4As shown, the second mounting portion 121 includes a boss portion 1211, a fastener 1212 and a deformation portion 1213. The boss portion 1211 protrudes from the top surface of the second guard plate 12, so that the boss portion 1211 protrudes upward from the top surface of the second guard plate 12, which can shorten the distance between the second mounting portion 121 and the sub-frame, and facilitate the connection between the second mounting portion 121 and the sub-frame. The top wall of the boss portion 1211 is formed with a mounting hole, and the mounting hole is used to install the fastener 1212. The fastener 1212 is connected to the sub-frame by passing through the mounting hole. The deformation portion 1213 is sleeved on the outer periphery of the fastener 1212, and at least a portion of the deformation portion 1213 is located in the mounting hole. When the sub-frame moves relative to the second guard plate 12, the deformation portion 1213 in the mounting hole will be deformed under the action force between the fastener 1212 and the second guard plate 12. The deformation portion 1213 in the mounting hole can generate radial compression to adapt to the radial movement of the sub-frame relative to the second guard plate 12.

[0042] According to some embodiments of the present invention, Figure 4 As shown, a groove is formed on the bottom surface of the boss portion 1211, and a limiting ring 1211a is provided on the inner peripheral wall of the groove. The limiting ring 1211a is an annular structure surrounding the inner peripheral wall of the groove, and may be integrally formed with the inner peripheral wall of the groove, or may be a separately attached component. The limiting ring 1211a is a structure such as a metal part, which can provide higher structural strength, so that the deformation portion 1213 can be evenly stressed when under pressure, further improving the stability and reliability of the connection. The limiting ring 1211a and at least another part of the deformation portion 1213 are abutted against the axial direction of the fastener 1212, and when the sub-frame moves relative to the second guard plate 12, the deformation portion 1213 can generate compression in the axial direction to adapt to the axial movement of the sub-frame relative to the second guard plate 12.

[0043] According to some embodiments of the present invention, Figure 4 As shown, the fastener 1212 includes a lining plate 1212a and a bolt 1212b. The lining plate 1212a is arranged on the bottom wall of the boss portion 1211 to provide additional support and stability, so that the connection between the boss portion 1211 and the sub-frame is more secure. At least another part of the deformation portion 1213 is arranged on the lining plate 1212a and is axially stopped with the stop ring 1211a of the fastener 1212. The deformation portion 1213 on the lining plate 1212a can produce axial deformation under the axial pressure between the lining plate 1212a and the stop ring 1211a to adapt to the axial movement of the sub-frame relative to the second guard plate 12. The bolt 1212b is connected to the lining plate 1212a to form an integral structure, and the bolt 1212b passes through the mounting hole to be connected to the sub-frame.

[0044] According to some embodiments of the utility model, the deformation part 1213 is constructed as a rubber part and is fixed to the fastener 1212. The deformation part 1213 is made of rubber material. As an elastic material with good elasticity and deformability, rubber can be deformed under the action of external force and return to its original shape after the external force disappears, so that the rubber part can play a good buffering and shock absorbing role in the fastener 1212. The deformation part 1213 is fixed on the fastener 1212, which can simplify the installation process and fix the position of the deformation part 1213 relative to the fastener 1212. The deformation part 1213 can be better deformed under the action of the fastener 1212 to adapt to the movement of the sub-frame.

[0045] In a specific embodiment, the deformation part 1213 can be fixed together with the fastener 1212 through a vulcanization reaction, which is convenient for fixation and realizes a firm connection between the deformation part 1213 and the fastener 1212, while also ensuring that the elasticity and deformability of the rubber part will not be damaged due to the connection process.

[0046] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, the second mounting portion 121 is constructed to be a plurality of second mounting portions 121 spaced apart in the width direction of the second guard plate 12. By arranging a plurality of second mounting portions 121 spaced apart in the width direction of the second guard plate 12, the plurality of second mounting portions 121 can evenly distribute the load and reduce single-point force, thereby improving the stability of the entire structure and making the connection between the second guard plate 12 and the subframe more stable. The plurality of second mounting portions 121 spaced apart help to optimize the force distribution. When the second guard plate 12 is subjected to external force, the plurality of second mounting portions 121 can share the force together, making the force more even, reducing the phenomenon of local stress concentration, and further improving the stability of the structure.

[0047] According to some embodiments of the present invention, Figure 1 and Figure 2 As shown, a plurality of reinforcing ribs 122 extending along the length direction of the second guard plate 12 and spaced apart in the width direction are formed on the second guard plate 12. The overall strength of the second guard plate 12 can be effectively increased, so that the second guard plate 12 can better resist deformation and damage when subjected to external forces, thereby extending its service life. The arrangement of the reinforcing ribs 122 helps to optimize the stress distribution on the second guard plate 12. When subjected to external forces, the reinforcing ribs 122 can disperse and transfer stress, so that the second guard plate 12 is more stable and reliable when subjected to impact and vibration.

[0048] According to some embodiments of the present invention, Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the bottom guard plate assembly 1 also includes a third guard plate 13 and a fourth guard plate 14. The third guard plate 13 is connected to the second guard plate 12 to form an integral structure, which enhances the rigidity and stability of the structure, and at the same time can ensure the flatness of the bottom surface of the vehicle, thereby reducing wind resistance. A third mounting portion 131 suitable for connecting to the vehicle body bracket is formed on the third guard plate 13. The third mounting portion 131 can be connected to the vehicle body bracket by welding, bolt 1212b connection or other fixing methods to provide bottom protection for the vehicle body. The fourth guard plate 14 is connected to the third guard plate 13 to form an integral structure, which enhances the rigidity and stability of the structure, and at the same time can ensure the flatness of the bottom surface of the vehicle, thereby reducing wind resistance. A fourth mounting portion 141 suitable for connecting to the battery pack bracket is formed on the fourth guard plate 14. The fourth mounting portion 141 can be connected to the battery pack bracket by welding, bolt 1212b connection or other fixing methods to provide bottom protection for the battery pack.

[0049] According to some embodiments of the utility model, the first guard plate 11, the second guard plate 12, the third guard plate 13 and the fourth guard plate 14 are constructed as an integrally formed part. The integrally formed part means that the first guard plate 11, the second guard plate 12, the third guard plate 13 and the fourth guard plate 14 are formed in a continuous manufacturing process without additional connecting parts, reducing potential weak points or breaking points, thereby significantly improving the structural strength of the entire bottom guard plate assembly 1, and more effectively ensuring the flatness of the bottom surface of the vehicle. In addition, the manufacturing process of the bottom guard plate assembly 1 is simplified, which not only reduces the number of manufacturing steps and parts required, but also reduces production costs and manufacturing time.
