[0002] In current technology, the tire locking device is an important device on a vehicle. Whether it is used for anti-theft or parking, the tire locking device is an important structure that greatly affects the safety and user experience of the vehicle. When the tire locking device is applied to an electric bicycle, in order to ensure safety and easy control, when the vehicle stops moving after power is cut off, the tire locking device needs to lock the tire to ensure that the vehicle stops and cannot move. After searching, the patent with application number 202322534582.9 discloses an electric bicycle with a built-in tire locking device, including a locking flange, which is fixed to the turntable of the bicycle; a lock box, which is set on the bicycle frame, and the lock box includes a shell, a locking pin that can be extended and retracted on the vertical surface of the turntable, and an intermittent motion mechanism for driving the locking pin. The shell is provided with at least one through hole, and the locking pin extends from the through hole; the locking flange is provided with a plurality of locking grooves, and the locking grooves are provided with slopes on both sides; the end of the locking pin facing the lock groove is provided with a rounded corner or chamfer.

[0003] However, during actual use, the applicant found that when the electric bicycle was moving, the locking pin would frequently come into contact with the locking flange and the locking groove, causing the locking pin and the locking groove to wear too quickly. In view of this, we proposed an electric bicycle with a built-in tire locking device. Utility Model Content

[0020] See also Figure 1-3 As shown, the utility model provides a technical solution:

[0021] An electric bicycle with a built-in tire locking device includes a tire drive motor 1, which is fixedly mounted on the electric bicycle frame. A turntable 2 is fixedly connected to one side of the tire drive motor 1. A locking plate 3 is fixedly connected to the side of the turntable 2 away from the tire drive motor 1. A locking slot 31 is provided on the side of the locking plate 3 away from the turntable 2. A plurality of locking slots 31 are provided on the locking plate 3 in an annular array. A locking box 4 is fixedly mounted on the electric bicycle frame near the locking plate 3. A rotating handle 7 is rotatably connected to the interior of the locking box 4 via a rotating shaft 6. Both ends of the rotating shaft 6 are rotatably connected to the locking box 4 via bearings. The rotating handle 7 is sleeved and fixed to the rotating shaft 6. The front end of the turning handle 7 is fixedly connected with the locking head 5, and the side wall of the locking box 4 is provided with an avoidance notch 41. The avoidance notch 41 is located on the inner side of the circular protrusion 42. The locking head 5 moves from the inside of the locking box 4 to the outside of the locking box 4 through the avoidance notch 41. The locking head 5 is matched with the locking slot 31. The rear end of the turning handle 7 is fixedly connected with a magnetic suction block 8. An electromagnet 9 is fixedly installed on the inner side wall of the electromagnet 9. When the electromagnet 9 is energized, it can magnetically adsorb the magnetic suction block 8, so that the turning handle 7 rotates around the rotating shaft 6 and compresses the metal elastic sheet 10. The turning handle 7 and the inner side wall of the locking box 4 are elastically connected through the metal elastic sheet 10. One end of the elastic piece 10 is fixedly connected to the inner side wall of the locking box 4 where the electromagnet 9 is located, and the other end of the metal elastic piece 10 is fixedly connected to the tail of the turning handle 7. By energizing the electromagnet 9, the magnetic suction block 8 can be magnetically adsorbed, so that the turning handle 7 rotates around the rotating shaft 6 and compresses the metal elastic piece 10, so that the locking head 5 can be moved out of the locking slot 31, thereby realizing the smooth rotation of the locking disk 3 and the tire drive motor 1. After the electromagnet 9 is powered off, the turning handle 7 can be driven by the elastic force of the metal elastic piece 10 to reset and rotate around the rotating shaft 6, so that the locking head 5 is stuck in the locking slot 31, thereby locking the locking disk 3 and the tire drive motor 1, which can effectively To avoid excessive wear between the locking head 5 and the locking disk 3, when the electric bicycle is powered on, the electromagnet 9 is energized to magnetically attract the magnetic suction block 8, driving the turning handle 7 to rotate around the rotating shaft 6 to compress the metal elastic sheet 10, so that the locking head 5 is moved out of the locking slot 31, and the locking disk 3 and the tire drive motor 1 can rotate smoothly. When the electric bicycle is powered off, the electromagnet 9 is powered off and loses its adsorption effect on the magnetic suction block 8. At this time, under the elastic force of the metal elastic sheet 10, it can drive the turning handle 7 to return to its original position and rotate around the rotating shaft 6, so that the locking head 5 is stuck in the locking slot 31, thereby locking the locking disk 3 and the tire drive motor 1, and then locking the tire.

[0022] The front end of the locking head 5 is provided with a rounded corner portion 51. The setting of the rounded corner portion 51 enables the locking head 5 to be better locked in the locking slot 31. A circular protrusion 42 is provided on the outer wall of the locking box 4 near the locking head 5. The circular protrusion 42 fits with the locking disk 3. The setting of the circular protrusion 42 can fill the gap between the locking box 4 and the locking disk 3, preventing people from using sheet plates to insert between the locking disk 3 and the locking box 4, and blocking the locking head 5 to achieve theft, which is safer.

[0023] Working principle: During use, when the electric bicycle is powered on, the electromagnet 9 is energized to magnetically adsorb the magnetic suction block 8, driving the turning handle 7 to rotate around the rotating shaft 6 to compress the metal elastic sheet 10, so that the locking head 5 is moved out of the locking slot 31, and the locking disk 3 and the tire drive motor 1 can rotate smoothly. When the electric bicycle is powered off, the electromagnet 9 loses power and loses its adsorption effect on the magnetic suction block 8. At this time, under the elastic force of the metal elastic sheet 10, it can drive the turning handle 7 to rotate around the rotating shaft 6 to return to its original position, so that the locking head 5 is stuck in the locking slot 31, thereby locking the locking disk 3 and the tire drive motor 1, and then locking the tire.
