The locking plate 9 is made of metal material, and a tongue card is provided at the bottom of the locking plate 9. A baffle for pulling the locking plate 9 to flip is provided on the reset plate 6. The locking plate 9 made of metal has higher strength, which avoids the situation that the electric power-assisted bicycle cannot be locked due to breakage during use, and the setting of the baffle makes it easy for the reset plate 6 to pull the locking plate 9 to reset, thereby facilitating the unlocking of the electric power-assisted bicycle. A limit ring 10 is overlapped on the front side of the locking plate 9, and the limit ring 10 is fixedly installed on the surface of the limit shaft 8. An auxiliary plate 11 is overlapped on the front side of the mounting plate 1, and a connecting shaft 12 is overlapped inside the auxiliary plate 11. The limit shaft 8 and the connecting shaft 12 are both cylindrical structures. 8 and the connecting shaft 12 are made of metal. The metal limiting shaft 8 and the connecting shaft 12 are not easy to deform, which avoids the reset plate 6, the locking plate 9 and the auxiliary plate 11 being reset and flipped due to the deformation of the limiting shaft 8 and the connecting shaft 12, thereby ensuring that the electric power-assisted bicycle can be locked normally. A fixing ring 13 is fixedly arranged on the surface of the connecting shaft 12, and a locking groove 16 is opened on the surface of the locking ring 14. The number of locking grooves 16 is several, and the several locking grooves 16 are all opened on the surface of the locking ring 14 and are distributed in a circular array. Through the arrangement of several locking grooves 16, the wheel of the electric power-assisted bicycle can be locked when it is rotated to any position, avoiding the need to lock the wheel of the electric power-assisted bicycle at a specified position.A blocking plate 15 is overlapped on the front side of the reset plate 6. The blocking plate 15 is fixedly connected to the limit shaft 8 and the connecting shaft 12. A driving shaft is fixedly arranged on the front side of the auxiliary plate 11. The motor 2 drives the rotating shaft 3 to rotate, so that the tension spring 4 drives the reset plate 6 to separate from the locking plate 9 through the installation shaft 5, or drives the locking plate 9 to reset, so that the tongue card on the locking plate 9 is inserted into the locking groove 16, or the locking plate 9 is moved out, so as to facilitate the locking of the electric power-assisted bicycle. Secondly, when the electric power-assisted bicycle is locked by mistake, the tongue card of the locking plate 9 cannot be fully inserted into the locking groove 16, so that the tongue card of the locking plate 9 collides with the locking ring 14 and makes a sound, so that the electronic lock motor for the electric power-assisted bicycle is safer to use, and avoids the situation where the electric power-assisted bicycle is overturned due to mistaken locking, causing injuries to the user, thereby ensuring the safety of the user of the electric power-assisted bicycle.
[0022] The main controller of the electronic lock motor for the electric power-assisted bicycle can be a conventional known device for controlling such as a computer.
[0023] During use: when the electric power-assisted bicycle needs to be locked, the output end is driven to rotate by the motor 2, so that the tension spring 4 moves downward, so that the tension spring 4 pushes the reset plate 6 to rotate on the surface of the limit shaft 8 through the installation shaft 5, so that the reset plate 6 is separated from the locking plate 9, so that the locking plate 9 moves downward by its own gravity, and the auxiliary plate 11 is pushed to the right by the tension spring 4, so that the tongue of the locking plate 9 is inserted into the locking groove 16 provided on the locking ring 14. At this time, the right end of the limit ring 10 is inserted into the groove of the auxiliary plate 11, and the locking plate 9 is blocked by the auxiliary plate 11, thereby locking the vehicle of the electric power-assisted bicycle. When it is necessary to unlock, the rotating shaft is driven by the motor 2. 3 rotates in the opposite direction, so that the rotating shaft 3 drives the tension spring 4 to reset, and the tension spring 4 drives the reset plate 6 to reset through the installation shaft 5. During the reset process of the reset plate 6, the right inclined surface of the reset plate 6 pushes the driving shaft arranged on the auxiliary plate 11, so that the auxiliary plate 11 moves to the right, so that the auxiliary plate 11 is separated from the limiting ring 10, and the reset plate 6 drives the limiting ring 10 to reset, thereby unlocking the wheel of the electric power-assisted bicycle. When the electric power-assisted bicycle is locked by mistake during driving, since the locking ring 14 rotates with the wheel, the tongue card of the limiting ring 10 cannot be fully inserted into the square shaft bushing 17, so that the tongue card of the limiting ring 10 will continue to collide with the locking ring 14, and a collision sound will be emitted to remind the user.
[0024] To sum up, the electronic lock motor for the electric power-assisted bicycle drives the rotating shaft 3 to rotate through the motor 2, so that the tension spring 4 drives the reset plate 6 to separate from the locking plate 9 through the mounting shaft 5, or drives the locking plate 9 to reset, so that the tongue card on the locking plate 9 is inserted into the locking groove 16, or the locking plate 9 is moved out, so as to facilitate locking the electric power-assisted bicycle. Secondly, when the electric power-assisted bicycle is locked by mistake, the tongue card of the locking plate 9 cannot be fully inserted into the locking groove 16, so that the tongue card of the locking plate 9 collides with the locking ring 14 and makes a sound, thereby making the electronic lock motor for the electric power-assisted bicycle safer to use, and avoiding the situation where the electric power-assisted bicycle turns over due to mistaken locking, causing the user to be injured, thereby ensuring the safety of the user of the electric power-assisted bicycle, and is used to solve the problems raised in the above-mentioned background technology.
