[0002] Today, with the increasing development of technology, people's travel has become more and more convenient. Shared bicycles have unique advantages in environmental protection, green travel, etc. However, there are also many traffic accidents when riding shared bicycles. Relevant data shows that among more than 500 cycling death accidents every year, 75% of the deaths are caused by fatal head injuries. Medical research has found that wearing a helmet while cycling can prevent 85% of head injuries, greatly reducing the degree of injury and the accident mortality rate. Therefore, it is extremely important to wear a helmet while cycling.

[0003] At present, helmets are set on shared bicycles. When the helmets are not in use, they are placed in the basket for storage. In order to prevent the helmets from being lost, the helmets usually need to be locked in the basket. The existing helmet lock devices have complex structures, high costs, and poor stability. Therefore, we have proposed a new helmet lock device for shared bicycles. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0027] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0028] In the present application, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0029] In the related art, when the helmet is not in use, it is placed in the basket for storage. To prevent the helmet from being lost, the helmet usually needs to be locked in the basket. The existing helmet lock devices have complex structures, high costs, and poor stability.

[0030] To solve the problems in the related art to a certain extent, the embodiments of the present application provide a shared bicycle helmet lock device. When in use, only a rotatable fixing block 16 needs to be set on the lock block 15, so that when the lock block 15 enters the lock slot 131, it will squeeze the helmet downward.

[0031] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0032] Combined Figures 1 - 4 , the embodiments of the present application provide a shared bicycle helmet lock device, including a helmet frame 1; the helmet frame 1 includes: a placement groove 12 is opened inside a frame body 11; a helmet 13 is arranged on the top of the placement groove 12; a lock slot 131 is opened on the outer side wall of the helmet 13; a motor 14 is arranged inside the frame body 11; a lock block 15 is arranged at the output end of the motor 14; a fixing block 16 is arranged at the bottom of the lock block 15, is connected to the lock block 15 through a support rod 17, and the support rod 17 is rotatably connected to the fixing block 16.

[0033] When in use, the helmet 13 is placed into the placement slot 12 of the frame body 11, and then the motor 14 is controlled to drive the locking block 15 to rotate and turn into the locking groove 131 to fix the helmet 13. Before turning into the locking groove 131, the fixing block 16 at the bottom of the locking block 15 enters the locking groove 131. The fixing block 16 is squeezed and is in a parallel state, strengthening the fixation with the locking groove 131 and preventing a gap from appearing between the fixing block 16 and the locking groove 131.

[0034] Specifically, the use of the motor 14 is controlled by a wire, and the model is WS-63ZYT108-R. The controller is a brand supporting device.

[0035] In some embodiments, a first rubber pad 121 is arranged inside the placement slot 12. The first rubber pad 121 is arranged to facilitate the helmet 13 to squeeze the rubber pad downward. It has a certain elasticity to prevent the fixing block 16 from being unable to enter the locking groove 131.

[0036] In some embodiments, a shaft body 171 is arranged on the outer side wall of the support rod 17, and a fixing groove 161 for cooperating with the support rod 17 and the shaft body 171 is formed at the top of the fixing block 16. The support rod 17 is fixed in the fixing groove 161 of the fixing block 16 through the shaft body 171 and can rotate.

[0037] In some embodiments, a torsion spring structure 172 is arranged on the outer side wall of the shaft body 171. The arrangement of the torsion spring structure 172 enables the fixing block 16 to tilt before entering the locking groove 131 and better enter the locking groove 131.

[0038] In some embodiments, a second rubber pad 18 is arranged at the bottom of the fixing block 16. The arrangement of the second rubber pad 18 can better fix the fixing block 16 and the locking groove 131, preventing the helmet from shaking.

[0039] In some embodiments, an auxiliary component 2 is arranged inside the frame body 11. The auxiliary component 2 includes: a baffle 21 arranged inside the frame body 11 and located above the locking block 15. The baffle 21 can protect the locking block 15 from being damaged.

[0040] In some embodiments, the top of the baffle 21 is an arc structure. The arc structure design can reduce the impact force of foreign objects on the baffle 21 and facilitate the helmet 13 to fall into the placement slot 12.

[0041] In some embodiments, the baffle 21 is connected to the frame body 11 through a fixing bolt 22. The baffle 21 is fixed on the frame body 11 through the fixing bolt 22, facilitating the removal of the baffle 21 for replacement.
