A car autonomous support device and its support method

Abstract

The invention discloses an autonomous supporting device for a car and a supporting method thereof. The device of the present invention includes a sensor system, four electric cylinder support units placed under the chassis of the car and a plane support mechanism placed in the trunk of the car; The cylinder realizes that the electric cylinder support unit is folded under the car chassis under normal conditions, and is unfolded to support heavy objects in emergency situations; the plane support mechanism drives the lifting table and the scissor-type telescopic platform through the electric push rod three times, combined with the electromagnetic telescopic rod Drive the expansion and contraction of the scissor-type telescopic net, so that the plane support mechanism can be folded in the trunk under normal conditions, and can be unfolded to support heavy objects under emergency conditions. In the present invention, when an unknown object hits the car, it detects in advance through the ultrasonic sensor and speed sensor on the roof, and the controller controls the electric cylinder support mechanism and the plane support mechanism to support the roof, effectively protecting the car and the people in the car life safety.

Description

technical field [0001] The invention belongs to the technical field of car safety applications, and in particular relates to a car autonomous support device and a support method that are shrunk under the car chassis and in the trunk. Background technique [0002] Existing cars do not have support devices that are triggered actively when danger occurs. When large vehicles such as vans and muck trucks roll over during driving, there is a risk that the body will collapse and hit the car. In the process of driving, there is always a potential safety hazard of being hit by goods dropped by trucks or other unknown heavy objects, which not only seriously threatens the lives of car drivers and passengers, but also brings huge property losses to drivers. [0003] If before the body of a large vehicle or other unidentified heavy objects hit the car, the car can actively trigger a set of support devices, and use the support device to support the large vehicle body and other unidentifie...
