The front and rear, i.e. the front and rear direction of the truck, can be understood schematically with reference to the direction of fig. 1.

The retractable trunk lid apparatus in this embodiment includes a trunk lid 800 and a driving mechanism for driving the trunk lid 800 to extend to cover an upper opening of a cargo container or to retract. In addition, the retractable trunk lid panel apparatus further includes a first detecting element 100, a second detecting element 200 and a controller 300, the first detecting element 100 is used for detecting a vehicle speed, and may be a vehicle speed sensor provided in a general vehicle, the second detecting element 200 is disposed at an extending end of the trunk lid panel 800, and the trunk lid panel 800 in fig. 1 extends forward from the rear, so that the second detecting element 200 is disposed at a front end of the trunk lid panel 800, so that the second detecting element 200 may detect whether an obstacle exists at the extending side of the trunk lid panel 800, and the second detecting element 200 may be a photoelectric sensor. The controller 300 may be an electric control unit VCU of the truck, and the controller 300 may control the driving mechanism 700 to drive the truck cover 800 to extend or retract according to the detected vehicle speed and the obstacle signal.

The first detecting element 100 and the second detecting element 200 are both in signal connection with the controller 300, the controller 300 may prestore a set vehicle speed, for example, 80km/h, and when the first detecting element 100 detects that the overspeed exceeds the set vehicle speed and the second detecting element 200 does not detect an obstacle signal, the controller 300 outputs a signal to control the driving mechanism to start, so as to drive the cargo box cover 800 to extend. When the speed of a motor vehicle is higher promptly, can drive cargo box apron 800 and stretch out, this application is under high-speed driving state, and cargo box apron 800 can cover the upper portion opening of packing box 1000 completely, plays the function of sheltering from the interior goods of protection packing box 1000 simultaneously, has reduced whole car windage from aerodynamic's principle, when the freight train is electronic freight train (be electronic pick-up), then can improve the continuation of the journey mileage correspondingly. In a low-speed driving state, the wind resistance is small, and the influence on the driving range is small for the electric vehicle, and at this time, the trunk lid panel 800 can be retracted. The high speed and the low speed are divided according to actual requirements, that is, the set vehicle speed is used for dividing the high speed and the low speed, the high speed is higher than 80km/h, and the low speed is lower than 80km/h, and the set vehicle speed can be set to other values.

The telescopic cargo box cover plate device has the working process as follows:

when the first detection element 100 detects that the vehicle speed is 80km/h or more, the controller 300 controls the driving mechanism according to the received vehicle speed signal so as to drive the cargo box cover plate 800 to extend out of the cargo box 1000 and cover the upper opening of the cargo box 1000;

when the second sensing member 200 receives a signal that there is an obstacle in front of the trunk lid 800 in the trunk 1000, the controller 300 controls the driving mechanism to stop its operation according to the received signal that there is an obstacle, thereby stopping the forward extension of the trunk lid 800. The cargo box cover 800 is now in a semi-closed position. Therefore, in the present embodiment, the coverage area of the cargo box cover 800 can be determined according to the cargo stacking state in the cargo box 1000, so that the degree of freedom of the user for the storage space of the cargo in the cargo box 1000 is improved, and the design is more humanized.

When the second sensing member 200 does not receive any obstacle signal, the trunk lid panel 800 continues to move forward until the trunk lid panel 800 is in the fully closed state. The wind resistance coefficient of the whole truck can be reduced by up to 20cts compared with the opening state of the cargo box cover plate 800, and the low wind resistance can be ensured to move forwards when the truck is in a high-speed driving state, so that the endurance mileage is obviously improved.
