Description

Technical Field

[0001] The present application belongs to the field of electric bicycle accessories, and specifically relates to a lifting structure of a deflector cover. Background Art

[0002] A shroud is an aerodynamic device installed on the front of an electric bicycle, also known as a wind plate or wind deflector, used to improve riding comfort and efficiency. The shroud changes the direction and speed of the airflow, reducing the generation of vortices and turbulence, thereby reducing air resistance and the drag coefficient. This reduces air resistance and improves the endurance and driving stability of the electric bicycle. It can also protect the rider from wind, sand and rain to a certain extent and can be used as a windshield. The shroud is usually composed of a hard shell cover, which can be pressed from thin steel plates or made of fiberglass. As an important riding auxiliary device, the shroud of an electric bicycle is of great significance for improving the riding experience and comfort. The shroud is generally connected to the frame tube of the electric bicycle. The shroud in the existing technology is fixed with a bracket and screws. This single fixing method cannot adjust the height of the shroud, is not suitable for people of different heights, and cannot meet the needs of different riders. Summary of the Invention

[0003] In view of the problems existing in the prior art, the utility model provides a lifting structure of a deflector cover, which is used to adjust the height of the deflector cover to meet the comfort level of people of different heights riding electric bicycles.

[0006] Furthermore, the iron track ring includes two parallel L-shaped tracks and a connecting plate for connecting the two L-shaped tracks. The two L-shaped tracks are arranged opposite to each other. The space between the L-shaped tracks and the connecting plate constitutes a channel for sliding of the air deflector fixing piece. The connecting plate is fixedly connected to the electric vehicle frame tube, for example, by welding. A circular hole and a long hole are opened on the connecting plate, and the long hole is arranged above the circular hole.

[0007] Furthermore, the positioning holes are opened on the L-shaped track on one side of the long hole, and the plurality of positioning holes are sequentially spaced from bottom to top along the height direction of the L-shaped track.

When the air deflector needs to be adjusted upward, the telescopic rod 9 is pushed inward, and the telescopic rod 9 moves along the groove 1 7 until the telescopic rod 9 is completely out of the positioning hole 6. At this time, the spring 1 5 in the compressed state pushes the air deflector fixing part 3 to move upward, and the spring 2 8 and the telescopic rod 9 move upward with the air deflector fixing part 3. When the telescopic rod 9 moves to the second positioning hole When the air deflector fixing part 3 needs to be adjusted downward, the telescopic rod 9 is pushed inward to disengage it from the positioning hole 6. The sliding column 306 is held and the air deflector fixing part 3 is pushed downward. The extended rubber buffer connecting ring 11 applies a downward force to the air deflector fixing part 3 until the telescopic rod 9 encounters the next positioning hole 6. The telescopic rod 9 enters this positioning hole 6 and fixes the air deflector fixing part 3 at a lower position.
