[0026] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0027] Reference below Figure 1-Figure 2 The transmission guard plate 100 according to the embodiment of the present utility model is described, which can increase the protection area, increase the protection force directions, and improve the heat dissipation.

[0028] Combination Figure 1 and Figure 2 As shown, the transmission guard plate 100 according to the first aspect embodiment of the utility model includes a main board 1 and a longitudinal beam side flange 2, the main board 1 is arranged below the transmission, and one lateral edge of the main board 1 extends obliquely away from the other side in the direction from front to rear, the longitudinal beam side flange 2 is arranged on one lateral edge of the main board 1, and the longitudinal beam side flange 2 is bent upward relative to the main board 1, and the longitudinal beam side flange 2 is suitable for being located between the transmission and the longitudinal beam 300.

[0029] Specifically, the main board 1 is located below the transmission, and one lateral edge (that is, the left-right direction) of the main board 1 extends obliquely from front to back away from the other side. The longitudinal beam side flange 2 is connected to one lateral edge of the main board 1, and is bent upward relative to the main board 1. This can increase the weight and spatial mode of the main board 1, thereby increasing the structural strength and bending and torsional stiffness of each other, and can also make the shape of the main board 1 close to the longitudinal beam 300 more match the structural extension profile of the longitudinal beam 300; in addition, the longitudinal beam side flange 2 is suitable for being located between the transmission and the longitudinal beam 300, so that the flange connected to the lateral edge of the main board 1 can protect the transmission in the lateral direction. In summary, compared with traditional transmission guards, the transmission guard 100 in this case has a larger protection area and more protective force directions, thereby improving the safety and reliability of the transmission guard 100.

[0030] In particular, the main board 1 is only located below the transmission. Compared with the traditional whole-type transmission guard plate (the transmission guard plate 100 is arranged as a whole below the exhaust pipe 200 and the transmission), the heat carried by the exhaust pipe 200 in this case will not be blocked by the main board 1 when dissipating, thereby improving the heat dissipation efficiency.

[0031] Therefore, by providing the transmission guard plate 100 , the protection area can be increased, the protection force directions can be increased, and the heat dissipation can be improved, thereby improving the safety, reliability and practicality of the transmission guard plate 100 .

[0032] According to some optional embodiments of the utility model, the longitudinal beam side flange 2 is bent and arranged obliquely upward away from the main board 1 relative to the main board 1. In detail, in the direction from bottom to top, the longitudinal beam side flange 2 is bent and extended obliquely upward away from the main board 1 relative to the main board 1, so that on the one hand, the longitudinal beam side flange 2 can form a protective force-bearing structure for the transmission in the lateral direction, and on the other hand, since the longitudinal beam side flange 2 is bent and extended obliquely relative to the main board 1, relative to the vertical bending and extension, the stress concentration problem at the connection between the longitudinal beam side flange 2 and the main board 1 can be reduced, thereby improving its structural reliability. In addition, since the longitudinal beam side flange 2 tends to increase its opening toward the side of the transmission, this is also conducive to improving the assembly convenience of the transmission guard 100.

[0033] According to some optional embodiments of the utility model, the transmission guard plate 100 also includes an exhaust pipe side flange 3, which is arranged at the other lateral edge of the main board 1, and the exhaust pipe side flange 3 is bent upward relative to the main board 1, and the exhaust pipe side flange 3 is suitable for being located between the transmission and the exhaust pipe 200.

[0034] Specifically, the exhaust pipe side flange 3 is connected to the other lateral edge of the main board 1, and the exhaust pipe side flange 3 is bent upward relative to the main board 1, so that the weight and spatial mode of the main board 1 can be increased, thereby increasing the structural strength and bending and torsional rigidity of each other; wherein, the exhaust pipe side flange 3 is suitable for being located between the transmission and the longitudinal beam 300, so that the exhaust pipe side flange 3 connected to the other lateral edge of the main board 1 can protect the transmission in the horizontal direction, and can also play a role in separating the exhaust pipe 200 and the transmission. In summary, compared with the traditional transmission guard, the transmission guard 100 in this case can further increase the protection area and increase the protection force direction, thereby improving the safety and reliability of the transmission guard 100. In addition, the exhaust pipe side flange 3 separates the exhaust pipe 200 and the transmission, which can also prevent the heat carried by the exhaust pipe 200 from being dissipated to the inside of the transmission guard 100.

[0035] According to some optional embodiments of the utility model, a first reinforcing rib 11 protruding upward is formed on the main board 1, and the first reinforcing rib 11 has a central reinforcing portion 111 and a plurality of extended reinforcing portions 112, the plurality of extended reinforcing portions 112 are connected to the central reinforcing portion 111, and the plurality of extended reinforcing portions 112 are arranged around the central reinforcing portion 111.

[0036] Furthermore, a first reinforcing rib 11 with a large area protruding upward is formed on the main board 1, so that the spatial mode of the main board 1 can be increased, thereby improving the bending and torsional rigidity of the main board 1; and the central reinforcing portion 111 of the main board 1 is located in the middle area of ​​the main board 1, and one end of the multiple extended reinforcing portions 112 is connected to the central reinforcing portion 111, and the other ends of the multiple extended reinforcing portions 112 extend on the main board 1 in different directions, so that the central reinforcing portion 111 can focus on strengthening the bending and torsional rigidity of the weak stress-bearing area in the center of the main board 1, and the multiple extended reinforcing portions 112 can also form a structural reinforcement effect on the main board 1 in different directions, thereby improving the overall structural strength of the main board 1 and reducing the dynamic stress of the overall structure of the main board 1. In addition, compared with the traditional arrangement of only criss-cross reinforcing ribs, the arrangement of the first reinforcing ribs 11 in this case is more reasonable and scientific.

[0037] Specifically, the plurality of extending reinforcement portions 112 include a first extending reinforcement portion 1121 and a second extending reinforcement portion 1122 . The first extending reinforcement portion 1121 extends to the other lateral edge of the mainboard 1 , and the second extending reinforcement portion 1122 extends to one lateral edge of the mainboard 1 .

[0038] It can be understood that the first extended reinforcement portion 1121 and the second extended reinforcement portion 1122 extend to the two side edges of the mainboard 1 in the lateral direction respectively, so that the first reinforcement rib 11 can extend to the edge area where the force is weak, thereby improving the structural strength and bending and torsional stiffness of the two side edges of the mainboard 1 in the lateral direction, and then improving the structural reliability of the mainboard 1.

[0039] Furthermore, the plurality of extended reinforcement portions 112 include a third extended reinforcement portion 1123, the third extended reinforcement portion 1123 includes a first reinforcement segment 11231 and a second reinforcement segment 11232, the first reinforcement segment 11231 is connected to the central reinforcement portion 111, and the first reinforcement segment 11231 extends backward, the second reinforcement segment 11232 is connected to the first reinforcement segment 11231, and the second reinforcement segment 11232 extends to a lateral side edge of the main board 1.

[0040] That is to say, the front end of the first reinforcement segment 11231 is connected to the central reinforcement portion 111, the rear end of the first reinforcement segment 11231 extends backward, and the rear end of the first reinforcement segment 11231 is connected to one end of the second reinforcement segment 11232, the second reinforcement segment 11232 changes the extension direction of the first reinforcement segment 11231, and the other end of the second reinforcement segment 11232 extends to the lateral side edge of the main board 1, so that the third extension reinforcement portion 1123 can form a coherent extension path, thereby improving processing consistency.

[0041] Specifically, the multiple extended reinforcement portions 112 include a fourth extended reinforcement portion 1124, which is connected to the central reinforcement portion 111 and extends forward; wherein a second reinforcement rib 12 protruding upward is formed on the main board 1, the second reinforcement rib 12 extends laterally, and the second reinforcement rib 12 is connected to the fourth extended reinforcement portion 1124.

[0042] It can be understood that the main board 1 is formed with a second reinforcing rib 12 protruding upward in the transverse direction, the rear end of the fourth extended reinforcing portion 1124 is connected to the central reinforcing portion 111, the fourth extended reinforcing portion 1124 extends forward, and the front end of the fourth extended reinforcing portion 1124 extends to the second reinforcing rib 12, so that the spatial mode of the main board 1 in different directions can be increased, and the first reinforcing rib 11 and the second reinforcing rib 12 can also form a coherent whole, thereby improving the bending and torsional rigidity and processing consistency of the main board 1. In addition, the second reinforcing rib 12 is close to the frame crossbeam, so that the installation point position on the main board 1 close to the frame crossbeam can also be effectively protected, reducing the stress response at the installation point, thereby improving the structural reliability of the main board 1.

[0043] Furthermore, the main board 1 forms an airflow channel 13 around the first reinforcing rib 11 through the first reinforcing rib 11, and the rear end of the airflow channel 13 extends to the rear edge of the main board 1. Among them, since the first reinforcing rib 11 on the main board 1 protrudes upward, a flow channel for airflow is formed around the first reinforcing rib 11, and the rear end of the airflow channel 13 extends to the rear edge of the main board 1. The first reinforcing rib 11 is constructed as a coherent whole, so the airflow can smoothly flow from the front of the main board 1 through the airflow channel 13 to the battery pack behind the main board 1, thereby also dispersing part of the heat of the transmission and the battery panel, thereby improving the heat dissipation.

[0044] According to some optional embodiments of the utility model, the longitudinal beam side flange 2 is provided with a third reinforcing rib 21 extending in the up-down direction. In detail, in the up-down direction, the longitudinal beam side flange 2 is provided with a third reinforcing rib 21 extending vertically, so that the spatial mode of the longitudinal beam side flange 2 can be increased, thereby improving the bending and torsional rigidity of the longitudinal beam side flange 2.

[0045] The vehicle according to the second aspect of the utility model includes a transmission, a longitudinal beam 300 and the transmission guard plate 100 of the above-mentioned embodiment. The vehicle with the transmission guard plate 100 can increase the protection area and force direction of the transmission, and can also improve the heat dissipation of the battery pack on the rear side of the frame, thereby improving the safety and practicality of the vehicle.
