Alternatively, the elastic member 7 may be a spring or other elastic connection member.
In this embodiment, the elastic member 7 is a spring. Because the windshield glass 2 is a glass with a slight radian, the windshield glass 2 can be cleaned when the windshield wiper strip 1 works by ensuring that the windshield wiper strip 1 is tightly attached to the windshield glass 2 through the elasticity of the springs at the two sides of the windshield wiper strip 1; in addition, the spring can absorb the length change caused by the non-parallelism of the sliding seats of the driving mechanisms 3 at the two sides of the wiper strip 1 or other reasons, so that the wiper strip 1 has an application range capable of moving left and right.
Further, as shown in fig. 3, a second hiding groove 81 is formed between the side trim 8 on each side of the windshield 2 and the back door outer panel 9, respectively. The two driving mechanisms 3 are respectively arranged in the two second hiding grooves 81, so that the driving mechanisms 3 can not be seen from the outer side, the appearance of a vehicle type is attractive, and the service life of the driving mechanisms 3 can be effectively prolonged.
In this embodiment, a side wall is provided on a side of the side decorative plate 8 away from the windshield 2, and a slit is provided between the side decorative plate 8 and the side wall, so that the side decorative plate 8 moves along with the opening and closing of the back door through the slit so as not to be affected by the side wall.

Specifically, the screw rotates under the driving action of the motor, so that the nut sliding block is driven to move up and down, and the nut sliding block drives the wiper strip 1 to move up and down through the elastic piece 7, so that the cleaning work of the windshield glass 2 can be performed.
Preferably, each of the above-mentioned side trim panels 8 is provided with a second bead 82 on the side facing the windshield 2. Through the second sealing rubber strip 82, not only the driving mechanism 3 can be shielded, so that a person cannot see the driving mechanism 3 from the outside, but also the sealing property between the side decorative plate 8 and the windshield glass 2 can be realized, so that dust, impurities or rainwater can be prevented from entering the second hiding groove 81 formed between the side decorative plate 8 and the back door outer plate 9, and the service life of the driving mechanism 3 is further prolonged.
As shown in fig. 2, when the driver starts the back door wiper strip function, the motor of the driving mechanism 3 at both sides of the wiper strip 1 drives the transmission shaft 31 to rotate, and then drives the sliding blocks 32 to move downwards along the transmission shaft 31, and the sliding blocks 32 at both sides drive the wiper strip 1 to leave the initial position through the elastic piece 7 and move downwards along the windshield 2; at this time, the decorative cover 4 is returned to the vertical state by being separated from the restrictions of the spoiler 6 and the windshield 2 while being restricted by the urging force of the torsion spring 52 and the stopper 13. Subsequently, the wiper strip 1 can be reciprocated longitudinally along the surface of the windshield 2 by the driving of the driving mechanism 3 to wipe the windshield 2.
When the driver closes the back door wiper strip function, the driving mechanism 3 drives the sliding blocks 32 to move upwards along the transmission shaft 31, and the sliding blocks 32 on two sides drive the wiper strip 1 to move upwards along the windshield 2 through the elastic piece 7 so as to gradually return to the initial position; in this process, the upper end of the decorative cover 4 rotates around the link 53 by abutting against the spoiler 6, and at this time, the decorative cover 4 drives the torsion spring 52 to disengage from the stopper 13 through the link 53 until the lower end of the decorative cover 4 rotates to abut against the windshield 2, and returns to the initial horizontal state.
The hidden electric back door wiper structure of the embodiment can solve the defects of the existing wiper in the aspects of smaller wiping range, durability and appearance; when the windshield is rained or the rear view of the driver is poor due to dirtying of the windshield, the driver can start the driving mechanisms according to actual conditions, drive the wiper strip to work through the two groups of driving mechanisms, wipe the visible area of the whole windshield through the longitudinal reciprocating motion of the wiper strip, improve the rear view range, and simultaneously, the decorative cover can rotate to be far away from the windshield under the action of the elastic rotating assembly so as to avoid affecting the wiping work of the wiper strip; when the wiper strip stops working, the wiper strip is hidden in the first hiding groove formed by the decorative cover and the spoiler, and the decorative cover rotates to the position that one end of the decorative cover is abutted against the spoiler, and the other end of the decorative cover is abutted against the windshield glass in a sealing way, so that the wiper strip is effectively prevented from being exposed, the aging time of the wiper strip is greatly prolonged, and the service life of the wiper strip is prolonged.
