Description

一种用于电动汽车的左右横梁A left and right cross beam for electric vehicle

技术领域Technical Field

本实用新型涉及一种用于电动汽车的左右横梁,属于汽车横梁技术领域。The utility model relates to left and right cross beams used for electric vehicles, belonging to the technical field of automobile cross beams.

背景技术Background technique

电动汽车是指以车载电源为动力,用电机驱动车轮行驶,符合道路交通、安全法规各项要求的车辆,由于对环境影响相对传统汽车较小,其前景被广泛看好,而电动汽车的发动机与电池组都安装在底盘内,这样重力都会作用在底板与左右横梁连接处,只通过螺栓固定连接容易导致错位的危险,而且为了避免汽车碰撞时出现严重损伤,会在前横梁处安装吸能盒,而现有的吸能盒为了刚度稳定,导致吸能盒本身吸能效果降低。An electric vehicle is a vehicle that uses an onboard power source as its motive force, uses an electric motor to drive the wheels, and complies with all requirements of road traffic and safety regulations. Since its impact on the environment is relatively small compared to traditional vehicles, its prospects are widely optimistic. The engine and battery pack of an electric vehicle are installed in the chassis, so gravity will act on the connection between the bottom plate and the left and right beams. The connection only by bolts can easily lead to the risk of misalignment. In order to avoid serious damage in the event of a car collision, an energy absorption box will be installed on the front beam. However, in order to stabilize the rigidity of the existing energy absorption box, the energy absorption effect of the energy absorption box itself is reduced.

本实用新型的有益效果是:The beneficial effects of the utility model are:

通过设置加强杆,在安装时,可以将加强杆两端的安装板落在横梁本体上,并通过固定螺栓固定连接,可以保持横梁本体整体的强度,而加强在支撑时,会通过安装板落在横梁本体上,从而确保电动汽车整体安装的可靠性;By setting the reinforcing rod, during installation, the mounting plates at both ends of the reinforcing rod can be dropped on the crossbeam body and fixedly connected by fixing bolts, so as to maintain the overall strength of the crossbeam body.
