[0035] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 13As shown, a helmet lock device for a shared two-wheeled vehicle includes a mounting base 10 fixed to the two-wheeled vehicle frame, a fixing plate 11 fixedly connected to the mounting base 10, and a helmet lock assembly 20 mounted on the fixing plate 11. A main lock hook 30 is provided on one side of the upper portion of the helmet lock assembly 20. The main lock hook 30 is provided with a main lock tongue 31 extending from the helmet lock assembly 20. The front end of the main lock tongue 31 abuts against a recessed hole 36 inside the main lock hook 30. The rear end of the main lock tongue 31 is fixedly connected to a first slide 21. The first slide 21 is sleeved on a double sliding shaft 22. A lock rack 23 is provided on the lower side of the first slide 21. The lock rack 23 meshes with an output gear assembly 24. The output gear assembly 24 is rotationally connected to a motor worm 251 of a motor 25 through a multi-stage speed change mechanism. The motor 25 is electrically connected to a control circuit board 26 in the helmet lock assembly 20. The control circuit board 26 is provided with a Bluetooth chip (not shown in the figure). The Bluetooth chip is wirelessly connected to the Bluetooth of the user's mobile phone. The user is the user who rents the shared two-wheeled vehicle.

[0037] Specifically, the main locking hook 30 is L-shaped and includes a front housing 32 and a rear cover 33. An NFC receiver 34 and a Hall effect PCB 35 are housed within the main locking hook. The NFC receiver 34 is vertically positioned, with its leads 340 inserted into the wire slot 321 of the front housing 32 and electrically connected to the control circuit board 26 via lead holes 330. The Hall effect PCB 35 is horizontally positioned within a housing cavity 331 of the rear cover 33. The leads 340 of the Hall effect PCB 35 are electrically connected to the control circuit board 26 via lead holes 330. The housing cavity 331 is waterproof.

[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 comprises a front lock housing 201 and a rear lock housing 202. A primary lock hook 30 is located on the front side of the front lock housing 201, with the hook of the primary lock hook 30 facing upward. A first slide 21 is arranged horizontally for forward and backward movement. The two slide shafts 22 are arranged in parallel. The front ends of the slide shafts 22 are inserted into axial holes (not shown) in the front lock housing 201, while the rear ends of the slide shafts 22 are inserted into axial holes (not shown) in the rear lock housing 202. The front lock housing 201 and the rear lock housing 202 are fastened together by screws (not shown).

[0040] Specifically, the left rear end of the first slide plate 21 is provided with a locking block 211 protruding to the left, and the right front end of the first slide plate 21 is provided with an unlocking block 212 protruding to the right. The locking block 211 contacts the locking touch switch 203 located on its front side, and the unlocking block 212 contacts the unlocking touch switch 204 located on its rear side. The locking touch switch 203 and the unlocking touch switch 204 have the same structure. The locking touch switch 203 and the unlocking touch switch 204 are each electrically connected to the control circuit board 26. The control circuit board 26 is disposed in a housing 261 on the front lock housing 201 to provide waterproofing. A filler 262 is provided on the outside of the control circuit board 26 to provide shockproofing. The control circuit board 26 draws power from the battery of the two-wheeled vehicle via a 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 away 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 dual-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 dual-gear clutch 208, and the third-stage gear / worm assembly 209 are respectively inserted into rotating shaft holes (not shown) in the lock front housing 201, while the rear ends of the rotating shafts of the first-stage worm gear / gear assembly 200, the second-stage dual-gear clutch 208, and the third-stage gear / worm assembly 209 are respectively inserted into rotating shaft holes in the lock rear housing 202. The second-stage dual-gear clutch 208 has the advantage of preventing jamming and protecting the gears and motor from damage in abnormal situations.

[0044] Specifically, the first worm gear 2001 of the first-stage worm gear / gear assembly 200 is rotationally connected to the motor worm 251, the first gear 2002 of the first-stage worm gear / gear assembly 200 is meshed with the second gear 2081 of the second-stage dual-gear clutch 208, the third gear 2082 of the second-stage dual-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 gear 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 engaged with a lock sleeve 41 provided on the rear edge of a helmet 40 for use with a two-wheeled vehicle. The main lock tongue 31 is inserted into a lock hole 411 within the lock sleeve 41 and locked. An NFC transmitter 412 is provided on the opposite side of the lock sleeve 41 from the lock hole 411. A Hall magnet mounting slot 413 is provided on the underside of the lock sleeve 41. After a Hall magnet (not shown) is inserted, a PVC sheet 414 is placed on the outer side of the lock sleeve 41. Specifically, the Hall magnet, in conjunction with the Hall PCB 35 and the control circuit board 26, intelligently determines the distance between the helmet 40 and the main lock hook 30. Locking is performed when the distance between the helmet 40 and the main lock hook 30 is within a safe distance. If the distance between the helmet 40 and the main lock hook 30 is not within the safe distance, locking is not performed. For example, if a user inserts the helmet 40 into the main lock hook 30 and then immediately removes it, the lock will not be locked, or if the helmet 40 is not properly placed, resulting in a large gap. This prevents the lock tongue from getting stuck or breaking.

[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 to the groove 213 on 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 a flat basket lock hole 28 is provided on the lock front shell 201 above the basket lock hook 52, and a spring hole 29 and a spring 53 extending backward are provided on the back side of the basket lock hook 52, 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 provided on the basket cover (not shown in the figure) of the basket is inserted into the basket lock hole 28 and buckled into 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 locking ring 54 includes a U ring 541 and a ring seat 542 vertically fixedly connected thereto.

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

[0048] Example 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 solution 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 rotation of the motor 25, 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 21, completing the simultaneous opening of the helmet lock and the basket lock, and opening the basket cover (not shown in the figure) to take out the helmet 40 for use. When arriving at the destination, take off the helmet 40, open the basket cover and put it 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 21, completing the simultaneous locking of the helmet lock and the basket lock.

[0051] It should be noted that in this embodiment, the main lock hook 30 is unlocked after the helmet 40 is removed. Depending on actual needs, this solution can also lock both the main lock hook 30 and the basket lock hook 52 simultaneously after the helmet 40 is removed. The locking trigger signal is automatically generated by the Hall PCB 35 after Bluetooth unlocking. The unlocking trigger signal is automatically generated by the NFC receiver 34 when the helmet 40 is returned after use. This method only requires the corresponding modification of the preset program in the control circuit board 26.

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

[0053] Compared with the prior art, the beneficial effects of the present invention are:

[0054] This solution not only solves the problems of helmets on shared two-wheeled vehicles being prone to broken ropes, lost keys, and theft, but also takes into account the locking of the basket, with 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 facilitates the U-shaped lock ring of the basket cover to press down (to make the spring retreat) to lock, and the lower surface of the hook end is inclined, which facilitates the basket cover to force upward (to make the spring retreat) to buckle the U-shaped lock ring to disengage 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, quickly and reliably. 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 solution utilizes a worm, worm wheel, and mating gears to form a multi-stage speed change mechanism, improving rotational stability and reducing mechanical noise. The first slide, the key component in the locking action, utilizes a sleeved double-sliding shaft structure, offering advantages such as high mechanical strength, wear resistance, smooth and flexible movement, and excellent stability. The simple structure of the first slide linking the second slide allows for a low-cost dual-purpose lock, simultaneously locking both the helmet and the basket. This results in a 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 for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
