[0002] Electric bicycles are vehicles that use batteries as auxiliary energy and are equipped with motors, controllers, batteries, throttles, brakes and other operating components and display instrument systems based on ordinary bicycles. Electric bicycles now play an important role in our lives, but existing electric bicycles still have the following problems in daily use:

[0003] In order to make the seat cushion of electric bicycles more resistant to dirt, the seat cushions are now made of black leather. As a result, in the hot summer, when the electric bicycle is placed outside and exposed to the sun, the seat cushions will be extremely hot. When the working people go out get off work at noon, the seat cushions will be extremely hot. Especially in the summer, they generally do not wear very thick pants. After sitting on the seat cushion, the high temperature will quickly transfer to the rider's buttocks, causing discomfort to the rider, so how to solve this problem needs to be considered.

[0016] Figure 3 for Figure 2 Enlarged view of point A.

[0017] In the figure: 1 U-shaped mounting frame, 2 mounting seat, 3 seat body, 4 rotating shaft, 5 connecting box, 6 pulling plate, 7 pulling groove, 8 sliding cavity, 9 sliding bar, 10 spring, 11 rectangular opening, 12 supporting plate. DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3 A foldable seat structure for an electric bicycle includes a U-shaped mounting frame 1, which is composed of a horizontal plate and two vertical plates. A mounting seat 2 is arranged between the two vertical plates. The lower end surface of the mounting seat 2 is horizontal. A rotating shaft 4 is fixedly connected to the left and right sides of the mounting seat 2. The other ends of the two rotating shafts 4 are rotatably connected to the corresponding vertical plates. A seat body 3 is installed on the upper end of the mounting seat 2.

[0020] The device further includes a support mechanism, which includes a support plate 12 disposed below the mounting seat 2, wherein the upper end of the support plate 12 contacts the lower end surface of the mounting seat 2;

[0021] It also includes a moving mechanism, which is used to move the support plate 12. The moving mechanism includes a connecting box 5 fixedly connected to the right side of the U-shaped mounting frame 1, a sliding cavity 8 is arranged in the connecting box 5, and a sliding bar 9 that can slide left and right is arranged in the sliding cavity 8. A rectangular opening 11 is opened on the left inner wall of the sliding cavity 8. The right side of the support plate 12 passes through the rectangular opening 11 and extends into the sliding cavity 8. The right side of the support plate 12 is fixedly connected to the left side of the sliding bar 9. The right side of the sliding bar 9 is fixedly connected with a pull plate 6. The right side of the pull plate 6 passes through the right inner wall of the sliding cavity 8 and extends to the outside. The right side of the sliding bar 9 is elastically connected to the right inner wall of the sliding cavity 8 through a plurality of springs 10. The pull plate 6 is located in the outer part and is penetrated by a pulling groove 7 in an up and down shape.

[0022] When the seat body 3 is not in use for a long time in hot summer, the user only needs to pull the pull plate 6 to move right, drive the sliding bar 9 and the support plate 12 to move right, until the support plate 12 moves right into the rectangular opening 11. At this time, the rotation of the mounting seat 2 is no longer restricted. The user can rotate the rotating seat 2 180° so that the entire seat body 3 faces downward, and then release the pull plate 6. Under the elastic action of the spring 10, the sliding bar 9 and the support plate 12 move left. The support plate 12 moves left and contacts with the right side of the seat body 3. At this time, the spring 10 is in a compressed state, and the left side of the support plate 12 gives the seat body 3 a large squeezing force. A certain friction force will be generated between the two, making it difficult for the seat body 3 to rotate at this time. When the seat needs to be rotated later, it is only necessary to pull the pull plate 6 to move right, and then flip the seat body 3 back to the initial position, and then release the pull plate 6. Finally, the support plate 12 will move back to its upper end surface and contact with the lower end surface of the mounting seat 2, and limit it again.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
