A brand-new suitcase car has the problem that the lid of the trunk can not be raised. After receiving the car: there are three reasons to analyze the reason that the luggage cover can not be pop-up. One is adding the reverse car image system on the sedan, increasing the weight of the luggage cover; two because the vehicle license plate has the decorative frame, the plate frame is mostly metal material (increasing the license plate after the license plate is about 0.6kg), and the increase of the weight multiplied force. After the arm is enlarged to a larger torque, the lid of the trunk can not be automatically activated after the license is installed; three, the temperature outside the vehicle is below 0 C. When the outside temperature is below 0 C, if there is water on the cover of the trunk, the weight of the cover of the trunk will be increased or the cover of the trunk is frozen together with the body freezing, and the pressure in the air pressure spring will decrease with the temperature decrease, which causes the case that the cover of the trunk can not be automatically opened. Adjust the spring hook to second empty seats for the failure of the new sagitta trunk lid which can not be automatically blown up by the above reasons. Maintenance summary: the problem of automatic opening of a new rapid suitcase cover can not be automatically opened. It is not necessary to change the pressure spring of the trunk and change the position of the spring (left and right sides).
