[0033] The sliding mechanism 4 includes a chute 401 and a Hall element 405. A slider 402 is arranged inside the chute 401. A connecting rod 403 is fixedly arranged at the front middle end of the slider 402 and extends into the installation shell 1. A baffle 404 is fixedly arranged at one end of the connecting rod 403 away from the slider 402. The Hall element 405 is fixedly arranged on one side inside the installation shell 1 and corresponds to the baffle 404. The speed control switch 2 is fixedly arranged at the front end of the installation shell 1. The motor switch 3 is fixedly arranged at the front end of the installation shell 1 and is located above the speed control switch 2. The speed control switch 2 is set to control the speed controller 5, and the motor switch 3 is set to control the operation of the motor 1102. A speed controller 5 is fixedly arranged on one side at the lower end inside the installation shell 1. A connecting pipe 6 is fixedly arranged in the middle of the installation shell 1. A first hook 7 is fixedly arranged at the upper end inside the installation shell 1. A return spring 8 is sleeved on the outer wall of the connecting pipe 6, and the return spring 8 is clamped on the first hook 7. The speed controller 5 is set to adjust the vehicle speed control. By arranging the return spring 8 on the connecting pipe 6, the rotation of the handle 10 is reset. The slider 402 is limited to slide in the chute 401, and the slider 402 slides in the chute 401, thereby realizing the limit of the slider 402. The magnetic induction mechanism 9 includes a disc 901. An installation block 902 is fixedly arranged at the front end of the disc 901. A magnet 903 is fixedly arranged inside the installation block 902. The magnet 903 is set to generate a magnetic field with the Hall element 405;

[0034] Refer to Figure 1 , 4 and 5, the ventilation mechanism 11 includes a fixed bracket 1101, an air inlet 1104, and an air outlet 1105. A motor 1102 is fixedly arranged inside the fixed bracket 1101. The output end of the motor 1102 is fixedly connected with a fan blade 1103. A plurality of air outlets 1105 are evenly arranged on the outer wall of the rotating handle 10. Screens 1106 are fixedly arranged inside all eight air outlets 1105. The air inlet 1104 is opened in the middle of the rear end of the rotating handle 10. The air outlet 1105 is opened to blow out the wind.

The second hook 12 is set to prevent the return spring 8 from moving its position.

[0035] In the embodiment of the present utility model, for the bicycle body with an electronic throttle structure, during riding, the speed controller 5 is controlled by the speed regulation switch 2 to regulate the vehicle speed of the bicycle body. Pressing different gears of the speed regulation switch 2 controls different vehicle speeds. At this time, when the rotating handle 10 is rotated, the magnetic field between the magnet 903 on the rotating handle 10 and the Hall element 405 changes according to different gears. The electronic throttle structure equipped with the speed regulation switch 2 has a simple structure and accurate and efficient gear shifting and speed changing.

[0036] Working principle: When the electronic throttle structure and the variable-speed bicycle are in use, the speed of the bicycle is controlled by controlling the speed of the speed controller 5 through the speed regulation switch 2. Pushing the slider 402 to move drives the connecting rod 403 to move, which in turn drives the baffle 404 to move. When the baffle 404 moves above the Hall element 405, at this time, when the rotating handle 10 is rotated again, the magnet 903 cannot generate a magnetic field with the Hall element 405, and the throttle stops working. The reset spring 8 is respectively clamped on the first hook 7 and the second hook 12 in the mounting shell 1 and the rotating handle 10. When the rotating handle 10 is rotated and then released, under the action of the reset spring 8, the rotating handle 10 is reset. The motor 1102 is controlled to rotate through the motor switch 3, which drives the fan blade 1103 to rotate, and the wind is blown out through the air outlet 1105. The blown wind can dry the sweat on the rider's hand and also blow out the dust that has fallen into the handle, improving the comfort and service life of the handle.

[0037] Finally, it should be noted that the above are only the preferred specific embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing specific embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
