Description

Technical Field

[0001] The utility model relates to the field of new energy automobile accessories, in particular to an automobile lower guard plate. Background Art

[0002] The rear motor of an electric vehicle usually refers to the electric motor installed at the rear of the electric vehicle. It plays an important role in the design and manufacture of electric vehicles, affecting the acceleration performance, driving stability and handling of the vehicle. Similar to traditional cars, the rear motor needs to be protected at the bottom of the vehicle body. Existing vehicle underbody guards, such as an underbody guard assembly mentioned in application number: CN202321369355.9, are provided with reinforcing ribs in the middle to increase the strength of the underbody guard. However, the ground conditions and risks faced by the edge of the underbody guard are the same as those in the middle of the underbody guard. Only providing a reinforcing rib structure in the middle cannot enhance the edge strength of the underbody guard. In addition, if functional holes such as drainage holes are provided, the structural strength of the part with the holes is also insufficient, resulting in defects in the overall strength of the underbody guard. Summary of the invention

[0003] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0004] Provided is an automobile underbody guard plate, which enhances the overall strength of the underbody guard plate.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automobile underguard, comprising a plate body, wherein the plate body comprises a front motor underguard, a battery pack underguard and a rear motor underguard which are longitudinally arranged in sequence, the lateral sides of the battery pack underguard respectively form trapezoidal openings with the front motor underguard and the rear motor underguard, the front motor underguard, the battery pack underguard and the rear motor underguard are all provided with connection holes connected to the vehicle body, the front motor underguard, the battery pack underguard and the rear motor underguard are all provided with a plurality of middle reinforcing ribs in the middle, and the characteristic is that the edges of the front motor underguard and the rear motor underguard are provided with edge reinforcing ribs.

[0006] A further configuration of the utility model is that the edge reinforcement ribs include a first edge reinforcement rib and a second edge reinforcement rib parallel to the middle reinforcement rib, and the first edge reinforcement ribs are respectively arranged on the edge of one side of the trapezoidal opening of the front motor lower guard plate and the rear motor lower guard plate.

[0007] A further configuration of the utility model is that the second edge reinforcement ribs are respectively arranged on the edges of both sides of the front motor lower guard plate and the rear motor lower guard plate, the middle reinforcement ribs are arranged longitudinally, and the second edge reinforcement ribs are parallel to the middle reinforcement ribs.

[0008] The utility model with the above characteristics is provided with edge reinforcing ribs to increase edge strength.

[0009] A further configuration of the utility model is that the front motor lower guard plate and the rear motor lower guard plate are provided with a plurality of drainage holes.

[0010] A further configuration of the utility model is: the drainage hole includes a water outlet and a water outlet reinforcement rib arranged on the side of the water outlet away from the lower guard plate of the front motor, the water outlet reinforcement rib is arched upward, and the height of the water outlet reinforcement rib at one end of the water outlet is higher than the height of the end away from the water outlet.

[0011] The utility model with the above characteristics: the drainage hole is used to discharge the accumulated water above the plate body, the water outlet reinforcement ribs increase the structural strength at the water outlet, and the water outlet reinforcement ribs are arranged at the end of the water outlet away from the lower guard plate of the front motor, so that it is easier to discharge from the water outlet during the driving of the vehicle.

[0012] The beneficial effect of the utility model is to enhance the overall strength of the lower guard plate.

[0013] The utility model is further described in detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
