[0027] As shown in Figure 2 and Figure 3As shown in the figure, in one embodiment of the present application, the lock 21 further comprises a torque amplification device, which is installed in the shell 6, and comprises a worm wheel 9, a worm 10 and a gear set 11, wherein the worm 10 is in transmission connection with the driving device 2, the worm 10 is in meshing connection with the worm wheel 9, the worm wheel 9 is in meshing connection with the gear set 11, and an output shaft 12 is installed on the gear set 11 and is connected with the cam 1.

[0028] In the embodiment of the present application, the torque output by the driving device 2 can be amplified through the design of the worm wheel 9, the worm 10 and the gear set 11, so as to quickly drive the rotation of the cam 1, and the worm wheel 9 and the worm 10 can complete self-locking, which can prevent the cam 1 from being reversed.

[0029] In one specific embodiment of the present application, the driving device 2 can adopt a motor.

[0030] As shown in the figure, Figure 1 and Figure 4 In one embodiment of the present application, a partition plate 13 is arranged in the shell 6, and the shell 6 is divided into an upper layer and a lower layer by the partition plate 13, wherein the driving device 2, the position switch device 5 and the torque amplification device are located in the lower layer of the shell 6, and the cam 1 and the sliding device 3 are located in the upper layer of the shell 6.

[0031] As shown in the figure, Figure 4 In one embodiment of the present application, a stroke port 14 is formed in the partition plate 13, and the second protrusion 8 is located in the stroke port 14, so as to limit the rotation stroke of the cam 1 to 0°-190°.

[0032] As shown in the figure, Figure 2 and Figure 5 In one embodiment of the present application, the position switch device 5 comprises a lock-to-position switch and an unlock-to-position switch, and the second protrusion 8 respectively touches the lock-to-position switch and the unlock-to-position switch when the cam 1 rotates in different directions, so as to respectively sense the locking and the unlocking.

[0033] In the embodiment of the present application, when the lock-to-position switch and the unlock-to-position switch respectively sense the locking and the unlocking, the driving device 2 stops.

[0034] In one embodiment of the present application, the circuit board is also installed in the shell 6, and the locking-in-place switch and the unlocking-in-place switch are connected to the circuit board respectively, and the locking-in-place switch and the unlocking-in-place switch are micro switches. When the circuit board receives a locking instruction, the circuit board controls the motor to start, the motor drives the cam 1 to rotate, the cam 1 drives the locking pin 4 on the sliding device 3 to extend out of the shell 6, when the second protrusion 8 on the cam 1 touches the locking-in-place switch, the locking-in-place switch senses the locking signal, the locking-in-place switch transmits the locking signal to the circuit board, and the circuit board controls the motor to stop, thereby completing the locking. When the circuit board receives an unlocking instruction, the circuit board controls the motor to start, the motor drives the cam 1 to rotate in the opposite direction to the locking, when the second protrusion 8 on the cam 1 touches the unlocking-in-place switch, the unlocking-in-place switch senses the unlocking signal, the unlocking-in-place switch transmits the unlocking signal to the circuit board, and the circuit board controls the motor to stop, thereby completing the unlocking.

[0035] As shown in Figure 4 and Figure 5 Further, the position switch device 5 of the embodiment of the present application and the stroke hole 14 of the above-mentioned embodiment need to be further described. The rotation stroke of the conventional cam 1 is limited to 0°-180°, and in the embodiment of the present application, the rotation stroke of the cam 1 is limited to 0°-190°, thereby the rotation stroke of the cam 1 is over 10°. During the locking and unlocking, the driving device 2 drives the cam 1 to rotate, thereby the second protrusion 8 touches the locking-in-place switch and the unlocking-in-place switch. When the second protrusion 8 touches the locking-in-place switch and the unlocking-in-place switch, and the locking-in-place switch and the unlocking-in-place switch cannot sense the locking and unlocking, at this time, the cam 1 is limited in the stroke hole 14 after rotating 190°, thereby the cam 1 cannot continue to rotate, so as to avoid damaging the locking-in-place switch and the unlocking-in-place switch.

[0036] As shown in Figure 1 In one embodiment of the present application, the sliding device 3 is a sliding block, the bottom of the sliding block is provided with a sliding groove 15 matched with the first protrusion 7, and the first protrusion 7 is located in the sliding groove 15.

[0037] As shown in Figure 6 In one embodiment of the present application, the lock further comprises a guide rail 16, the sliding block passes through the guide rail 16, when the first protrusion 7 drives the sliding block to slide, the sliding block moves linearly on the guide rail 16, the partition plate 13 is further provided with a limiting block 17 corresponding to the guide rail 16, the limiting block 17 is provided with a limiting groove 18, and the two ends of the guide rail 16 are clamped in the limiting groove 18.

[0038] As shown in Figure 7 In another embodiment of the present application, the lock further comprises a support 19, and the support 19 forms a track for the sliding block to slide.

[0039] According to the lock 21 of the embodiment of the present application, the lock 21 drives the cam 1 to rotate through the driving device 2, the first protrusion 7 on the cam 1 drives the lock pin 4 on the sliding device 3 to extend and retract, so as to realize locking and unlocking, the second protrusion 8 on the cam 1 touches the position switch device, so as to sense locking and unlocking, and through the structural design of the first protrusion 7 and the second protrusion 8 on the upper surface and the lower surface of the cam 1, the overall structure of the lock can be made more simple.

[0040] At present, the helmet matched with the electric bicycle usually is limited on the electric bicycle by installing a rope or a latch on the helmet, so as to prevent the helmet from being lost or stolen. When the rope is installed, one end of the rope is fixed to the helmet, and the other end of the rope is fixed to the electric bicycle. When the latch is installed, the latch is installed on the helmet, and a helmet lock matched with the latch is installed in the basket, so as to limit the helmet in the basket. However, the above two methods will bring certain safety hazards. For example, when riding, the rope is easily hung or pulled by other objects along the way, so that a certain pulling force is generated on the head and neck of the user, which easily causes the user to be injured in the neck during riding, and even causes the bicycle to fall. Further, when falling or the bicycle falling occurs during riding, due to the pulling effect of the rope on the head and neck of the user, the user is easily injured twice on the basis of the conventional falling, which causes the user to be seriously injured or even die, and increases the safety hazards during riding. The method of installing the latch on the helmet cannot guarantee the integrity of the helmet, reduces the strength of the helmet, and also brings certain safety hazards.

[0041] Based on the lock 21 of the above embodiment, the present application further provides an electric bicycle.

[0042] As shown in Figure 8 The electric bicycle of the embodiment of the present application includes a storage structure 20 and a lock 21. The storage structure 20 has an opening, and the lock 21 is installed at the opening of the storage structure 20, so as to limit the objects in the storage structure 20 in the locked state.

[0043] The above embodiment has described the lock 21, which will not be repeated here.

[0044] As shown in Figure 9As shown, in the specific embodiments of the present application, the object in the storage structure 20 can be a helmet 23. The bottom of the storage structure 20 is also provided with a lock control device 22, which is in communication connection with the circuit board. The lock control device 22 is provided with a card reader. The lock control device 22 is in wireless communication connection with the helmet 23 in the storage structure 20 through Bluetooth. The helmet 23 is provided with an infrared sensor, a human body sensing sensor and a three-axis sensor, which are used to determine whether the user wears the helmet 23. The infrared sensor, the human body sensing sensor and the three-axis sensor cooperate with the Bluetooth technology to transmit the wearing condition of the helmet 23 of the user to the background system. The electric bicycle can appropriately prompt the user who does not wear the helmet 23, so as to better guide the user to develop the good habit of wearing the helmet 23, improve the wearing rate of the helmet 23 and protect the user's travel safety. The helmet 23 is also provided with an NFC card. The NFC card and the card reader in the lock control device 22 are used in cooperation to determine whether the user returns the helmet 23.

[0045] In the specific embodiments of the present application, when the helmet 23 is locked, the lock control device 22 sends a locking instruction to the circuit board. After the circuit board receives the locking instruction, the motor is controlled to start. The motor drives the cam 1 to rotate. The cam 1 drives the locking pin 4 on the sliding device 3 to extend out of the shell 6 through the first protrusion 7. When the second protrusion 8 touches the locking-in-place switch, the locking-in-place switch senses the locking signal and transmits the locking signal to the circuit board. The circuit board controls the motor to stop. The locking is completed. Thus, the helmet 23 is limited in the storage structure 20 by the locking pin 4 to achieve the anti-theft function of the helmet 23. When the helmet 23 is unlocked, the lock control device 22 sends an unlocking instruction to the circuit board. After the circuit board receives the unlocking instruction, the motor is controlled to start. The motor drives the cam 1 to rotate in the opposite direction of the locking direction. The cam 1 drives the locking pin 4 on the sliding device 3 to retract into the shell 6 through the first protrusion 7. When the second protrusion 8 touches the unlocking-in-place switch, the unlocking-in-place switch senses the unlocking signal and transmits the unlocking signal to the circuit board. The circuit board controls the motor to stop. The unlocking is completed.

[0046] Compared with the above-mentioned limiting mode of the helmet 23 at the present stage, the lock 21 is integrally installed on the storage structure 20. The helmet 23 is limited in the storage structure 20 by the locking pin 4 to prevent the helmet 23 from being lost or stolen. In addition, it is not necessary to additionally install a limiting device on the helmet 23, which ensures the integrity of the helmet 23.

[0047] According to the electric bicycle, the lock 21 is integrally installed on the storage structure 20, the driving device 2 in the lock 21 drives the cam 1 to rotate, the cam 1 drives the lock pin 4 on the sliding device 3 to extend and retract to realize locking and unlocking, and the helmet 23 is limited in the storage structure 20 when locked, so that the helmet 23 is prevented from being lost or stolen. In addition, the corresponding limiting device does not need to be installed on the helmet 23, the integrity of the helmet 23 is ensured, the strength of the helmet 23 is improved, and therefore, the safety of wearing the helmet 23 is improved.
