Hydrogen energy automobile engine cover jacking device

Abstract

The invention provides a hydrogen energy automobile engine cover jacking device. The hydrogen energy automobile engine cover jacking device comprises a hydrogen tank, a sensor, an electronic control module and a jacking assembly. The jacking assembly is arranged below an engine cover. The jacking assembly comprises a sleeve and a push rod. The upper end of the push rod is connected with a jackingsupport. The lower end of the push rod is connected with a piston. The lower end of the push rod is inserted into the upper end of the sleeve. The lower end of the sleeve is connected with the hydrogen tank through a hydrogen pipe. A solenoid valve is arranged on the hydrogen pipe. The sensor is arranged in a foam anti-collision beam. The sensor is connected with an airbag controller. The airbag controller is connected with the electronic control module. The electronic control module is connected with the solenoid valve. The airbag controller detects whether a pedestrian is collided or not andtransmits a jacking signal to the electronic control module. The electronic control module controls the solenoid valve to be turned on, hydrogen is input into the sleeve, and the push rod jacks up the engine cover. The hydrogen energy automobile engine cover jacking device has the beneficial effects of absorbing energy generated when the pedestrian collides with the engine cover to protect the pedestrian against secondary injury. There is no need to adopt a gas generator to implement ignition to jack up the engine cover. Thus, the weight is reduced, and the hydrogen energy automobile engine cover jacking device is good in sealing and pressure maintaining effect and higher in reliability.

Description

technical field [0001] The invention relates to the technical field of hydrogen energy vehicles, in particular to a hydrogen energy vehicle hood jacking device. Background technique [0002] As a real clean energy vehicle, hydrogen energy vehicles are gradually entering the market, and their safety requirements are getting higher and higher. The gas generator used in the traditional hood jacking mechanism for pedestrian protection is detonated, and the piston push rod is pushed up by generating a large amount of high-temperature gas, and the piston push rod then jacks up the hood, which is heavy and the generator takes a long time Unstable, high temperature after ignition and other disadvantages. Contents of the invention [0003] In view of this, an embodiment of the present invention provides a hydrogen vehicle hood jacking device. [0004] An embodiment of the present invention provides a hydrogen energy vehicle hood jacking device, including a hydrogen tank, a sensor...
