Electric automobile front cabin mounting bracket and electric automobile

Abstract

The invention discloses an electric automobile front cabin mounting bracket and an electric vehicle, and belongs to the technical field of electric vehicles. A first mounting area and a second mounting area are connected in the first direction, the first mounting area is used for supporting and fixing one, two or three of a power distribution unit, a vehicle-mounted charger, a motor control unit and a battery, and the second mounting area is used for supporting and fixing the rest of the power distribution unit, the vehicle-mounted charger, the motor control unit and the battery; a vacuum boosting main cylinder is arranged above the joint of the first mounting area and the second mounting area in the second direction; the first direction is perpendicular to the second direction; a strengthweakening structure is arranged at the joint of the first mounting area and the second mounting area; the maximum breaking stress capable of being borne by the joint in the second direction is lowerthan a preset breaking stress value, the maximum breaking stress capable of being borne by other positions of the first mounting area and the second mounting area in the second direction is higher than the preset breaking stress value, and the mounting bracket can effectively avoid the vacuum boosting main cylinder and is low in cost.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle front cabin mounting bracket and the electric vehicle. Background technique [0002] The rigid wall collision conditions of 50km / h and the variable barrier collision conditions of 64km / h are the specified conditions in China's new car evaluation regulations. For front-drive electric vehicles, especially range-extending vehicles, in addition to conventional powertrain components, they also need to integrate PDU (Power Distribution Unit, power distribution unit), OBC (On Board Charger, on-board charger) and MCU (Motor Control Unit, motor Control unit) and other three-electric high-voltage electrical components, and meet the collision requirements: not only to avoid high-voltage electrical components directly hitting the vacuum booster master cylinder, resulting in excessive intrusion of the brake pedal in the passenger compartment in a frontal collisio...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to propose a front compartment mounting bracket of an electric vehicle and an electric vehicle, so that the vehicle can effectively avoid the vacuum booster master cylinder when the vehicle collides with a low cost, thereby solving the problem of the frontal collision of the vacuum booster master cylinder. The problem of excessive intrusion of the brake pedal due to the brake pedal in the passenger compartment, and reduces the probability of leakage of high-voltage electrical components due to impact
