Description

Technical Field

[0001] This utility model belongs to the field of helmet locks, specifically relating to a helmet, a bicycle basket, a helmet locking structure, and a shared bicycle. Background Technology

[0002] As a new member of modern urban green travel safety equipment, shared bicycle helmets are gradually becoming an indispensable protective item for cyclists. To provide convenience for cyclists, shared electric bikes are specially equipped with helmets, which need to be placed in the basket after the ride. However, storing helmets directly in the basket makes them easy to lose.

[0003] To address this issue, some existing shared electric bike scenarios provide helmets by attaching a drawstring to the helmet. However, this method still makes the helmets easy to lose, and the drawstring can easily get caught on roadside objects during riding, posing a safety risk.

[0004] In addition, some existing shared electric bikes are equipped with helmet locks. The helmet lock is located in the middle of the basket, with locking pins on both sides. The lock is achieved by inserting the locking pins into the helmet hole inside the helmet. However, in order to complete the synchronous action of the locking pins on both sides, the locking pin drive structure is relatively complex, has a high failure rate, is not convenient for later maintenance, and is not suitable for widespread application in shared electric bikes. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0049] To prevent the loss of helmets associated with shared bicycles, existing technologies use pull cords or helmet locks as anti-theft measures. With pull cords, the helmet is always connected to the bicycle during riding. If the cord accidentally snags on an object on the roadside, it can easily cause the bicycle to lose balance and tip over, posing a significant safety hazard. Existing helmet locks are located in the middle of the basket, locking with pins on both sides that engage with the helmet's internal locking mechanism. To achieve synchronized action of the pins, the locking mechanism needs a complex design, greatly increasing the probability of mechanical failure and requiring frequent repairs. Furthermore, given the widespread deployment of shared bicycles and the difficulty of centralized management and maintenance, existing helmet locks are unsuitable for large-scale application on shared bicycles. Moreover, the presence of a lock mechanism at the bottom of the basket compromises its original storage function.

[0050] Based on the above problems, this utility model makes an overall improvement to the helmet and basket. The lock body is set on the side wall of the basket, and a protruding locking piece is set on the outside of the helmet shell. When the helmet is placed in the basket, the locking piece can fall into the locking area of ​​the lock body to lock the helmet. In this way, the helmet can be locked in a direction parallel to the tangential plane of the side wall of the basket and outside the helmet shell. This simple locking pin drive mechanism can achieve helmet locking. Based on this inventive concept, this application provides a matching helmet, basket, helmet locking structure, and a shared bicycle with the above components. The helmet locking structure includes a locking piece set on the helmet and a lock body set on the basket. The locking piece can be locked in the locking area of ​​the lock body by a locking pin set on one side. The driving method of the locking pin is simple in structure and can adopt the mature locking pin drive technology developed by our team. It has a low failure rate, a long service life of the lock body, and reduces the difficulty and cost of later maintenance. The helmet locking structure provided by this utility model can simultaneously take into account the safety of riding, the reliability of the lock body structure, and the functionality of the basket itself.

[0051] Please refer to the attached document as well. Figure 1 To be continued Figure 6 The helmet locking structure provided by this utility model will now be described. The helmet locking structure, used to lock the helmet 20 into a matching basket 10, includes a lock body 40 and a locking plate 22. The lock body 40 is provided on the basket 10 and is fixed to the helmet 20 from the outside. A locking pin 42 on the lock body 40 is inserted into the locking plate 22 of the helmet 20 from one side, thereby locking the helmet 20. Specifically, the lock body 40 is assembled on an inner side wall of the basket 10. The lock body 40 includes a lock housing 41 and a locking pin 42 assembled within the lock housing 41, as well as a matching locking pin drive mechanism. The lock housing 41 has a guide groove 411 and a locking pin hole 412 on one side wall of the guide groove 411, suitable for the locking pin 42 to extend or retract. A locking plate 22 is provided on the helmet 20. When the helmet 20 is placed in the basket 10, the locking plate 22 is adapted to fall into the guide groove 411. The locking plate 22 is provided with a locking hole 221 suitable for the insertion of the locking pin 42. When placing the helmet 20, align the locking plate 22 of the helmet 20 with the guide groove 411 of the lock body 40 and place it into the basket 10 to lock the helmet 20.

[0052] In this embodiment, locking the helmet 20 can be achieved simply by setting a locking pin 42 on one side of the guide groove 411, which simplifies the lock body structure, eliminates the need for a complex locking pin drive structure, reduces the probability of lock body 40 failure, extends the service life of lock body 40, and reduces maintenance difficulty.

[0053] In one embodiment, the guide groove 411 extends from the upper end face of the lock housing 41 along the direction in which the helmet 20 is placed into the basket 10. The locking pin 42 extends and retracts in a direction parallel to the tangential plane of the side wall of the basket 10 on the mounting side to lock or unlock the locking piece 22. The locking hole 221 passes through the locking piece 22. The length of the locking pin 42 is adapted to the width of the guide groove 411. When locking, the locking pin 42 is inserted into the locking hole 221 from the side, and its moving end abuts against the side wall of the guide groove 411. Alternatively, a locking pin hole 412 can be opened on the side of the guide groove 411 where the locking pin 42 is not provided, and the moving end of the locking pin 42 extends into the locking pin hole 412 on that side to ensure that the locking pin 42 will not come out of the locking piece 22, thus firmly fixing the locking piece 22 in the guide groove 411.

[0054] In this embodiment, the opening direction of the guide groove 411 is adapted to the direction in which the helmet 20 is placed into the basket 10, making it convenient for the rider to take the helmet 20 out and ensuring the ease of use of the product.

[0055] In one embodiment, the lock housing 41 is flat and fits snugly to one side wall of the basket 10. The guide groove 411 opens upward and extends along the vertical direction of the basket 10 to the middle of the lock housing 41. The lock body 40 is attached to the side wall of the basket 10, which does not affect the placement of items in the basket 10, does not take up too much capacity of the basket 10, and does not affect the normal use of the basket 10.

[0056] In one embodiment, the helmet 20 has an outer visor 21 at the back of the head, and a locking plate 22 at the lower end of the outer visor 21. When locked, the outer visor 21 abuts against the upper end of the lock body 40, which is suitable for blocking the locking plate 22 and the locking pin 42. It should be noted that the height of the outer visor 21 should be just enough to ensure that the locking plate 22 is fully inserted into the guide groove 411, so as to ensure that the locking pin 42 can be smoothly inserted into the lock hole 221.

[0057] In this embodiment, when locked, the outer edge 21 abuts against the upper end of the lock body 40, forming a shield above the guide groove 411, which can be used to protect the locking plate 22 and the locking pin 42, thereby improving the service life of the locking structure and reducing the later maintenance cost.

[0058] In one embodiment, the locking plate 22 is integrally formed with the back of the helmet 20 and the outer rim 21. The bottom contour of the guide groove 411 matches the locking plate 22.

[0059] Specifically, a locking pin drive mechanism for use in the helmet locking structure of the above embodiments is provided, including a motor 47, a transmission gear set 45, and a rack 44. The transmission gear set 45 and the rack 44 are connected between the motor 47 and the locking pin 42 to form a transmission structure. The motor 47 drives the locking pin 42 to extend or retract from the locking pin hole 412 of the lock body 40. Specifically, the fixed end of the motor 47 is fixedly installed in the lock housing 41, and its output end is equipped with a worm gear 46. The input wheel of the transmission gear set 45 meshes with the worm gear 46, and the rack 44 meshes with the output wheel of the transmission gear set 45. The rack 44 abuts against the locking pin 42 and is adapted to drive the locking pin 42 to extend or retract from the locking pin hole 412. Further, a return spring 43 is sleeved on the locking pin 42. One end of the return spring 43 is connected to the lock housing 41, and the other end is connected to the locking pin 42. A push plate 441 is provided at the end of the rack 44. Please refer to the attached drawing. Figure 6 When the rack 44 pushes the locking pin 42 to the right, the push plate 441 abuts against the tail end of the locking pin 42, pushing the locking pin 42 out of the locking pin hole 412; when the rack 44 moves to the left, the locking pin 42 moves to the left under the action of the return spring 43 and retracts from the locking pin hole 412.

[0060] In one embodiment, an identification chip is built into the rear end of the helmet 20. A control circuit 50 and an identification circuit 60 are disposed within the lock housing 41. The identification circuit 60 is signal-connected to the control circuit 50, and the control circuit 50 is signal-connected to the locking pin drive mechanism. When the helmet 20 is placed in the basket 10, the identification circuit 60 senses the signal from the identification chip inside the helmet 20 and sends it to the control circuit 50. The control circuit 50 controls the locking pin drive mechanism to drive the locking pin 42 out of the locking pin hole 412 and insert it into the locking hole 221 on the locking plate 22, thus locking the helmet 20. When a user scans a code to borrow the vehicle, the control circuit 50 drives the locking pin drive mechanism to perform an unlocking action, and the locking pin 42 retracts from the locking hole 221 on the locking plate 22 back into the lock housing 41, thus unlocking the helmet 20.

[0061] The working principle of this embodiment is as follows: After the control circuit 50 receives the locking signal sent by the identity recognition circuit 60, the control circuit 50 controls the motor 47 in the lock pin drive mechanism to run, which drives the transmission rack 44 to move through the transmission gear set 45, thereby driving the lock pin 42 to move; after the user successfully scans the code, the control circuit 50 receives the unlocking signal and controls the motor 47 to reverse, thereby controlling the rack 44 to move in the opposite direction, and the lock pin 42 is reset under the action of the reset spring 43.

[0062] It should be noted that the helmet locking structure provided in the above embodiments can be manufactured and sold as an independent product, or it can be used in shared bicycles as a component of shared bicycles.
