Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present invention provides a hood lifting device for a hydrogen-powered vehicle, including a hydrogen tank 2, a sensor 3, an electronic control module 4, and a lifting assembly 5.
Referring to fig. 2, the jacking assembly 5 is disposed below the bonnet 8 of the hydrogen energy automobile 1, the jacking assembly 5 includes a sleeve 13 and a push rod 12, the upper end of the push rod 12 is connected to a jacking bracket 14, the lower end of the push rod 12 is connected to a piston 15, the lower end of the push rod 12 is inserted into the upper end of the sleeve 13, the outer diameter of the piston 15 is equal to the inner diameter of the sleeve 13, and the piston 15 can slide up and down along the inner wall of the sleeve 13. The upper end of the jack-up bracket 14 is close to the back of the engine cover 8, and the two do not contact. In this embodiment, the jacking assembly 5 is disposed on the axis of the engine cover 8 and near the front windshield 9 of the hydrogen automobile 1, so as to achieve the effect of stably jacking the engine cover 8.
the sleeve 13 is fixed in the engine compartment 10 upper portion of hydrogen energy car 1, the sleeve 13 lower extreme passes through hydrogen pipeline 6 and connects hydrogen tank 2, the lower extreme of sleeve 13 is located to hydrogen pipeline 6 cover, and the two junction is equipped with sealing ring 16, sealing ring 16 is used for guaranteeing hydrogen pipeline 6 with concrete better leakproofness between the sleeve 13.
Be equipped with solenoid valve 7 on the hydrogen pipeline 6, sensor 3 is banded pressure sensor, sensor 3 set up in the anterior foam anticollision roof beam of hydrogen energy car 1, specifically along foam anticollision roof beam length direction arranges. The sensor 3 is connected with an air bag controller of the hydrogen energy automobile 1, the air bag controller is connected with the electric control module 4, and the electric control module 4 is connected with the electromagnetic valve 7.
The sensor 3 detects whether the front part of the hydrogen energy automobile 1 collides with a pedestrian, when the front part of the hydrogen energy automobile 1 collides with the pedestrian, the foam anti-collision beam can deform under stress, the sensor 3 detects the stress, the airbag controller can judge that the hydrogen energy automobile 1 collides with the pedestrian through the stress detected by the sensor 3, then a jacking signal is sent to the electronic control module 4, the electronic control module 4 controls the electromagnetic valve 7 to be opened according to the jacking signal, so that high-pressure hydrogen in the hydrogen tank 2 is input into the sleeve 13, the push rod 12 ascends under the action of air pressure, and the jacking support 14 jacks up the engine cover 8. At the moment, the hydrogen gas forms a gas spring between the piston 15 and the sleeve 13, the gas spring has a buffering effect on the pedestrian 11, the energy of the pedestrian 11 hitting the engine hood 8 is effectively absorbed, and secondary damage caused by the pedestrian 11 hitting the engine hood 8 is avoided.
In order to prevent the engine cover 8 from being damaged by the too high jacking height of the engine cover to the pedestrian 11, a pressure release valve is arranged on the sleeve 13, the pressure release valve is respectively connected with the electronic control module 4 and the air bag controller, and the air bag controller controls the pressure release valve to be opened when detecting that the air pressure in the sleeve 13 reaches a preset maximum threshold value. The maximum threshold value determines the lift height of the hood 8, and may be set according to actual conditions. When the pressure in the sleeve 13 is overlarge, the pressure in the sleeve 13 is reduced by controlling the opening of the pressure relief valve, so that the jacked height of the engine cover 8 is kept within the range of 80mm-150 mm. The pressure relief valve may also be used to release hydrogen gas inside the sleeve 13 after the hood 8 is lifted.
