The Hall PCB board 35 is horizontally arranged in the placement cavity 331 of the lock hook rear cover 33, and the lead 340 of the Hall PCB board 35 is electrically connected to the control circuit board 26 through the lead hole 330. The placement cavity 331 has a waterproof effect.

[0038] NFC is the abbreviation of Near Field Communication, which means near field communication in Chinese. It is an emerging technology. Devices using NFC technology can exchange data when they are close to each other.

[0039] Specifically, the helmet lock assembly 20 is provided with a lock front shell 201 and a lock rear shell 202, and the main lock hook 30 is provided at the front side of the lock front shell 201, with the hook of the main lock hook 30 facing upward. The first slide plate 21 is arranged horizontally and can move forward and backward, and the two slide shafts of the double slide shaft 22 are arranged in parallel, and the front end of the double slide shaft 22 is sleeved in the shaft hole (not shown in the figure) on the lock front shell 201, and the rear end of the double slide shaft 22 is sleeved in the shaft hole (not shown in the figure) on the lock rear shell 202.

The control circuit board 26 is arranged in the placement compartment 261 on the lock front shell 201, which can play a waterproof role. A filling piece 262 is provided on the outside of the control circuit board 26, which can play a shockproof role. The control circuit board 26 draws power from the battery terminal of the two-wheeled vehicle through the lead 340.

[0041] Specifically, the locking touch switch 203 is inserted into the locking positioning box 205 and fixed to the lock front shell 201, and the unlocking touch switch 204 is inserted into the unlocking positioning box 206 and fixed to the lock front shell 201. Since the unlocking positioning box 206 is farther from the lock front shell 201 than the locking positioning box 205, the screw column of the unlocking positioning box 206 is longer than the screw column of the locking positioning box 205.

[0042] Specifically, the output gear assembly 24 includes a fifth gear 241 on the right and a second worm gear 242 close to the left side of the fifth gear 241. Both ends of the output shaft 240 in the output gear assembly 24 are arranged in the output shaft groove 207 formed by the lock front shell 201 and the lock rear shell 202.

[0043] Specifically, the multi-stage speed change mechanism includes a first-stage worm gear / gear assembly 200, a second-stage double gear clutch 208, and a third-stage gear / worm assembly 209. The front ends of the rotating shafts of the first-stage worm gear / gear assembly 200, the second-stage double gear clutch 208, and the third-stage gear / worm assembly 209 are respectively sleeved in the rotating shaft holes (not shown) on the lock front housing 201, and the rear ends of the rotating shafts of the first-stage worm gear / gear assembly 200, the second-stage double gear clutch 208, and the third-stage gear / worm assembly 209 are respectively sleeved in the rotating shaft holes on the lock rear housing 202. The second-stage double gear clutch 208 has the advantages of preventing jamming and protecting the gears and the motor from damage in abnormal situations.

[0044] Specifically, the first worm wheel 2001 of the first-stage worm wheel / gear assembly 200 is rotationally connected to the motor worm 251, the first gear 2002 of the first-stage worm wheel / gear assembly 200 is meshed with the second gear 2081 of the second-stage double gear clutch 208, the third gear 2082 of the second-stage double gear clutch 208 is meshed with the fourth gear 2091 of the third-stage gear / worm assembly 209, the worm 2092 of the third-stage gear / worm assembly 209 is rotationally connected to the second worm wheel 242 of the output gear assembly 24, and the fifth gear 241 of the output gear assembly 24 is meshed with the lock rack 23.

[0045] Specifically, the main lock hook 30 is sleeved with the lock sleeve 41 provided on the rear edge of the helmet 40 matched with the two-wheeled vehicle, and the main lock tongue 31 is inserted into the lock hole 411 in the lock sleeve 41 and locked. The lock sleeve 41 is provided with an NFC transmitter 412 on the opposite side of the lock hole 411, and the lower side of the lock sleeve 41 is provided with a Hall magnet placement groove 413, and a PVC sheet 414 is covered on the outer side after the Hall magnet (not shown in the figure) is placed. In particular, after the Hall magnet of this scheme cooperates with the Hall PCB board 35 and the control circuit board 26, the distance of the helmet 40 relative to the main lock hook 30 can be intelligently judged. When the distance between the helmet 40 and the main lock hook 30 is a safe distance, the locking action is performed. If the distance between the helmet 40 and the main lock hook 30 is not within the safe distance, the locking action is not performed. For example, if the user puts the helmet 40 into the main lock hook 30 and then takes it away immediately, it will not be locked, or if the helmet 40 is not placed properly and a large gap is generated, not locking can protect the lock tongue from being stuck or broken.

[0046] Optionally, for a shared two-wheeled vehicle with a basket, a basket lock assembly is further provided on the upper part of the helmet lock assembly 20, and the basket lock assembly includes a second slide plate 50, and a downward protrusion 51 is provided on the middle part of the lower side of the second slide plate 50, and the protrusion 51 is slidably connected with the groove 213 in the middle part of the upper side of the first slide plate 21, and the left and right sides of the second slide plate 50 are inserted into the slide groove 27 formed by the lock front shell 201 and the lock rear shell 202, and the upper side of the second slide plate 50 is provided with a forward basket lock hook 52, and the lock front shell 201 above the basket lock hook 52 is provided with a flat basket lock hole 28, and the back side of the basket lock hook 52 is provided with a spring hole 29 and a spring 53 extending backward, and the rear end of the spring 53 is sleeved in the spring fixing groove (not shown in the figure) on the lock rear shell 202, and the U-shaped lock ring 54 arranged on the basket cover (not shown in the figure) of the basket is inserted into the basket lock hole 28 and buckled in the basket lock hook 52 for locking. For a shared two-wheeled vehicle without a basket, the basket lock hole 28 is blocked with a plug (not shown), and the second slide plate 50 and the spring 53 are removed. The U-shaped lock ring 54 includes a U ring 541 and a ring seat 542 vertically fixedly connected thereto.

[0047] Embodiment 1: A shared two-wheeled vehicle with a basket, in which a helmet seat 55 is provided for supporting a helmet 40, so that the helmet 40 can be placed more stably.

[0048] Embodiment 2: A shared two-wheeled vehicle without a basket, wherein a helmet seat 55 is fixedly connected to the lower end of the fixing plate 11 for supporting the helmet 40, so that the helmet 40 can be placed more stably.

[0049] The method of using the helmet lock device of this scheme is briefly described as follows:

[0050] When the helmet needs to be used, the user opens the mobile phone APP, presses the unlocking menu, and communicates with the Bluetooth chip on the control circuit board 26 through the mobile phone Bluetooth. The control circuit board 26 controls the motor 25 to rotate, and the lock rack 23 moves backward through the motor worm 251 and the multi-stage speed change mechanism, and drives the main lock tongue 31 and the basket lock hook 52 to move backward at the same time through the first slide plate 21, so that the helmet lock and the basket lock are opened at the same time, and the basket cover plate (not shown in the figure) is opened to take out the helmet 40 for use. When arriving at the destination, the helmet 40 is taken off, the basket cover is opened and put into the main lock hook 30, the NFC receiver 34 in the main lock hook 30 recognizes the signal of the NFC transmitter 412 on the helmet 40 and notifies the control circuit board 26, and at the same time, the Hall PCB board 35 in the main lock hook 30 detects the Hall magnet on the helmet 40 and notifies the control circuit board 26, and the control circuit board 26 controls the motor 25 to rotate in the opposite direction, and the lock rack 23 moves forward through the motor worm 251 and the multi-stage speed change mechanism, and drives the main lock tongue 31 and the basket lock hook 52 to move forward at the same time through the first slide plate 21, so that the helmet lock and the basket lock are locked at the same time.

[0051] It should be noted that the present embodiment adopts a method in which the main lock hook 30 is unlocked after the helmet 40 is taken out. According to actual needs, the present solution can also select that after the helmet 40 is taken out, the main lock hook 30 and the basket lock hook 52 are in a locked state at the same time, and the locking trigger signal is automatically generated by the Hall PCB board 35 after the Bluetooth unlocking is detected, and the unlocking trigger signal when the helmet 40 is put back after use is automatically generated by the NFC receiver 34. In this method, only the preset program in the control circuit board 26 needs to be modified accordingly.

[0052] The control circuit board 26, the Bluetooth chip and the Hall PCB board 35 in this solution all belong to the prior art, and their specific working principles and model specifications are not described in detail here.

[0053] Compared with the prior art, the present invention has the following beneficial effects:

[0054] This solution not only solves the problems of helmets on shared two-wheeled vehicles being prone to rope breakage, key loss, and theft, but also takes into account the locking of the basket at the same time, and has the advantage of one lock for two purposes. This solution is compatible with multiple models of shared two-wheeled vehicles with and without baskets. This solution supports the simultaneous locking and unlocking of the helmet lock and the basket lock, and also supports users to mechanically open and lock the basket at any time. This mechanical method is determined by the special structure of the hook end of the basket lock hook of this solution. The upper surface of the hook end is arc-shaped, which is convenient for the U-shaped lock ring of the basket cover to press down (make the spring retreat) to lock, and the lower surface of the hook end is inclined, which is convenient for the basket cover to force upward (make the spring retreat) to buckle up and make the U-shaped lock ring disengage from the basket lock hook to unlock. This solution uses an L-shaped main lock hook to lock the helmet, which has the advantages of being convenient for users to hang it directly, fast and reliable. The NFC induction automatic locking replaces the key, and the NFC transmitter is embedded in the helmet lock sleeve, eliminating the need to hold the NFC transmitter to trigger the operation, thereby improving the efficiency of locking. This scheme adopts a worm, a worm wheel and a matching gear to form a multi-stage speed change mechanism, which improves the stability of rotation and reduces mechanical noise. The key part of the locking action of this scheme, namely the first slide, adopts a sleeve double sliding shaft structure, which has the advantages of high mechanical strength, wear resistance, flexible and smooth movement, and good stability. The structure of the first slide to link the second slide is simple, and a one-lock dual-purpose is achieved at a low cost, and the helmet and the basket are locked at the same time, achieving the beneficial effects of compact overall structure, simple operation, and convenient and reliable locking.

[0055] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
