For the length setting of the drive chain 32, it needs to be set according to actual needs.

The following describes the specific principle of use of the present invention in conjunction with fig. 9 and 10 to facilitate understanding of the present invention:

as shown in fig. 9, the telescopic hood of the automobile is first mounted on the roof by glue or the like, and then four extension portions 332 of the four telescopic driving devices 3 are mounted on two a posts on both sides of the front windshield 103 and two C posts on both sides of the rear windshield 104, respectively. After the automobile telescopic hood is installed, the automobile telescopic hood is in a closed state, the remote controller 12 is used for controlling the automobile telescopic hood to be opened, the four motors 31 are started, the gears 34 are used for driving the transmission chains 32 to move towards the extending parts 332 in the main body 331, and the hood 2 is synchronously driven to extend out of the opening 5 from the storage gap 334.

As shown in fig. 10, when the motor 31 is stopped after the four driving chains 32 are moved in place, the cover cloth 2 is extended and opened, that is, the periphery of the cover cloth 2 is respectively laid on the front windshield 103, the rear windshield 104 and the side glass 105 on both sides, and the functions of sunshade, dust prevention, protection and the like are well performed on the positions.

Similarly, when the telescopic car cover of the car is controlled to be closed by the remote controller 12, the four motors 31 are started, and the four gears 34 drive the transmission chains 32 to move from the extension parts 332 to the main body 331. In the process of moving the transmission chain 32, the cover cloth 2 is synchronously driven to move into the inner cavity 4, and because the main body 331 is coiled, the four corners of the cover cloth 2 are correspondingly driven to move in the containing gap 334, namely, the periphery of the cover cloth 2 is correspondingly coiled to be contained in a more space-saving manner, until the transmission chain 32 is completely retracted into the main body 331 and then the cover cloth 2 is completely retracted into the inner cavity 4 through the opening 5, and at the moment, the motor 31 is stopped to finish coiling.

Embodiment two:

as shown in fig. 12, the present embodiment is different from the first embodiment in that the length of the extending portion 332 of the two front guide rails 33 is longer than the length of the extending portion 332 of the two rear guide rails 33, so that the extending portion 332 of the two front guide rails 33 can be allowed to continue to extend forward until extending to both sides of a head cover (not shown) on the vehicle body 100, preventing the normal opening of the head cover from being affected by the arrangement of the guide rails 33. Meanwhile, through the two guide rails 33 with the lengthened lengths arranged in the front, the cover cloth 2 can basically cover the head cover when being opened, so that the head cover can be well sun-shading, dustproof, protective and the like.

Of course, since the two sides of the head cover and the two a-pillars are bent, the extending portion 332 is correspondingly and correspondingly bent according to actual situations, so as to avoid that the telescopic car cover of the car cannot be installed correctly.

In summary, the four telescopic driving devices with the motors and the guide rails can drive the cover cloth to extend out of the opening or retract into the inner cavity in an electric driving mode, namely, the full-electric type spreading and rolling are realized, and the use is very convenient; the cover cloth can be respectively covered on the periphery of the upper end of the vehicle body after being opened, so that the front windshield, the rear windshield, the two side glasses and the like of the vehicle can be effectively covered, the effects of sun shading, dust prevention, protection and the like of the positions of various vehicle windows and the like are realized, and the practicability is strong; when the cover cloth is required to be stored, the cover cloth can be driven by the motor to move into the inner cavity until the cover cloth is completely stored in the inner cavity, so that the storage is completed, and the cover cloth is not easy to damage.
