[0028] The tarpaulin structure 203 includes a plurality of folding support rods 2031 and circular holes 2032, a tarpaulin 2033 and a limited folding joint 2034. The two folding support rods 2031 are connected by a limited folding joint 2034. The limited folding joint 2034 is provided with a circular hole 2032. The folding support rod 2031 is inserted into the elastic support rod 201 by the circular hole 2032 on the limited folding joint 2034. The tarpaulin 2033 is connected with the limited folding joint 2034 on the folding support rod 2031. Open the front box 1, rotate the support rod 102 with one end of the shaft fixed to the two ends of the main beam 101 by ninety degrees to stand upright and self-lockingly fix it, then stretch the horizontal top support rod 104 together with the transparent film on the transparent film reel 103 and buckle it between the support rod 102, and fasten the two sides of the transparent film through opening and closing zippers or Velcro. It is locked in position with the support rod 102 to form an independent front windshield device in front of the vehicle body. Then, the trunk 2 is opened. Through the elastic support rod 201, the folding support rod 2031 and the round hole 2032, the tarpaulin 2033 is fully stretched. Then, the top of the tarpaulin 2033 is limitedly unfolded to both sides by 180 degrees using the limited folding joint 2034, thereby expanding the shielding area. Then, the locking structure 204 in the trunk 2 is used to limit the elastic support rod 201. The tarpaulin 2033 can be fixed by inserting the pin 4 on the elastic support rod 201 into the lock buckle 3. Conversely, the switch is pressed to pull out the pin 4, and the locking structure 204 is released to retract the tarpaulin. The transparent film reel 103 is then used to reel in the transparent film to complete the folding and storage of the shelter. It is easy to use, improves the aesthetics and quality, and enriches the choices and usage scenarios of consumers.

[0029] Furthermore, the trunk 2 can be installed in the trunk body on the rear seat bracket of the vehicle body or installed on both sides of the rear wheels under the rear seat bracket of the vehicle.

[0030] Furthermore, the support rod 102 is rotatably connected to both sides of the main beam 101 by means of rivets 111, the transparent film on the transparent film reel 103 is connected to the horizontal top support rod 104 and can be stretched to be buckled and mounted on the support rods 102 on both sides, the transparent film on the transparent film reel 103 and the support rod 102 are locked and positioned by opening and closing zipper pieces or Velcro, the transparent film on the transparent film reel 103 is stretched and buckled between the support rods 102, and the two sides of the transparent film are locked and positioned with the support rods 102 by opening and closing zipper pieces or Velcro, so that an independent front windshield device is formed in front of the vehicle body.

[0031] Furthermore, a spring pin unlocking buckle 105 is provided on the top of the main cross beam 101 , and an externally threaded spring pin 106 is provided in the inner cavity of the support rod 102 .

[0032] Furthermore, both ends of the main crossbeam 101 are penetrated by a hand screw rail 107, the inner cavity of the hand screw rail 107 is provided with a hand screw 108, the outer part of the hand screw 108 is screwed with a square nut 109, the inner wall of the hand screw rail 107 is provided with a limit rail 110, and the square nut 109 is slidably connected to the inner cavity of the limit rail 110. After opening the front box 1, the support rod 102 can be rotated ninety degrees under the action of the hand screw rail 107 and the limit rail 110 under the action of the rivet 111, and then the spring pin unlocking buckle 105 and the external thread spring pin 106 are used for preliminary fixation, and then the hand screw 108 is rotated to cooperate with the square nut 109 to fix the support rod 102 for the second time. Otherwise, the support rod 102 can be put into the front box 1, which improves the temporary stability of the retractable and extendable electric bicycle while improving the convenience of folding and unfolding.

[0033] Furthermore, the elastic support rod 201 is made of elastic thin tube material and is not limited to carbon fiber or glass fiber rods. The elastic support rod 201 can be pulled out from the winding disc 202 or rolled inwardly by relying on its own bendable physical property.

[0034] Working principle: When using this retractable and extendable temporary shelter for electric bicycles, open the front box 1, rotate the support rods 102 with one end of the shaft fixed to the two ends of the main beam 101 by 90 degrees and fix them upright and self-lockingly, then stretch the horizontal top support rod 104 together with the transparent film on the transparent film winder 103 and buckle them between the support rods 102, and lock the two sides of the transparent film with the support rods 102 by opening and closing zippers or Velcro, so that an independent front windshield device is formed in front of the vehicle body, then open the rear box 2, and through the elastic support rod 201, cooperate with the round hole 203 on the folding support rod 2031 and the limit folding joint 2034. 2. After the tarpaulin 2033 is fully stretched, the top of the tarpaulin 2033 is limitedly unfolded to both sides by the limit folding joint 2034, so as to expand the shielding area, and then the locking structure 204 in the trunk 2 is used to limit the elastic support rod 201, and the pin 4 on the elastic support rod 201 is inserted into the lock 3 to fix the tarpaulin 2033. Conversely, the switch is pressed to pull out the pin 4, and the locking structure 204 is released to retract the tarpaulin, and then the transparent film retractor 103 is used to rewind the transparent film to complete the folding and storage of the shelter. It is easy to use, improves the aesthetics and quality, and enriches the choices and usage scenarios of consumers.
