Description

Technical Field

[0001] This utility model relates to the field of helmet lock technology, and in particular to a shared helmet shopping basket device. Background Technology

[0002] With the rise of ride-sharing, the government has increasingly stringent requirements for travel safety, leading to the widespread adoption of shared helmets on shared electric bicycles. However, helmet theft prevention has become a major challenge for the industry. Currently, most helmet locks on the market rely on pins or straps on the helmet for locking and securing. This design itself poses security risks and significantly impacts user experience. Therefore, finding a safer and more convenient helmet anti-theft solution has become an urgent issue for the industry. Utility Model Content

[0003] This invention solves the problems in related technologies and proposes a shared helmet basket device. The rib design at the bottom of the basket restricts the movement of the helmet in the first direction. At the same time, the rotating locking tongue limits the helmet in the second direction. This multi-dimensional limiting system achieves complete locking of the helmet at low cost without any additional devices, ensuring the integrity of the helmet.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a shared helmet basket device, including a helmet body, a basket and a lock body. The helmet body has grooves on both sides. The basket is provided with a limiting rib at the position corresponding to the groove to limit the helmet body in a first direction. A ventilation hole is provided on the front side of the helmet body. The lock body rotates and extends into the ventilation hole to limit the helmet body in a second direction.

[0005] As a preferred embodiment, the lock body includes a motor and a bolt. The bolt is mounted on an output shaft, and a half gear is mounted on the output shaft. The motor is connected to the half gear through a transmission assembly to drive the bolt to rotate, thereby realizing unlocking and locking.

[0006] As a preferred embodiment, the transmission assembly includes a worm, a worm wheel, and a gear set, wherein the worm meshes with the worm wheel, the worm wheel meshes with a second gear via a first gear, and the second gear meshes with a half gear.

[0007] As a preferred embodiment, the bottom of the half gear is provided with a protrusion and a clutch spring is sleeved on the protrusion. The clutch spring presses the last tooth of the half gear onto the first gear to achieve disengagement.

[0008] As a preferred embodiment, the lock body further includes a PCBA board, on which a micro switch is provided, and a connector for driving the micro switch is installed on the output shaft. When locking, the connector rotates to the position of the micro switch, presses it, and transmits a signal to the controller.

[0009] As a preferred embodiment, the PCBA board communicates with the controller via CAN bus or 485 communication, or is directly driven by the controller.

[0010] As a preferred embodiment, the shared helmet basket device further includes a wearing detection module electrically connected to the controller. The wearing detection module includes a Bluetooth module and a sensor, both of which are built into the helmet body. The helmet body communicates with the lock body via the Bluetooth module and detects whether the helmet is being worn via the sensor.

[0011] As a preferred embodiment, the shared helmet basket device further includes a helmet return detection module electrically connected to the controller, which is used to detect whether the helmet body is returned to the basket.

[0012] As a preferred embodiment, the helmet detection module includes a magnetic switch mounted on the PCBA board and a magnet built into the helmet body. After the magnetic switch senses that the magnet is in place, it transmits a signal to the controller.

[0013] As a preferred embodiment, the helmet detection module includes a card reader built into the lock body and an NFC card, IC card, or ID card built into the helmet body. The card reader reads the NFC card, IC card, or ID card and transmits the signal to the controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The locking tongue extends by rotating and inserts into the front ventilation hole of the helmet. This design effectively limits the helmet and ensures its stability.

[0016] (2) The rib design at the bottom of the basket restricts the movement of the helmet in the first direction. At the same time, the rotating locking tongue limits the helmet in the second direction. This multi-dimensional limiting system achieves full locking of the helmet at low cost without any additional devices, ensuring the integrity of the helmet.

[0017] (3) The transmission components can amplify the torque, making operation easier, and the half gears can be used to achieve self-locking.

[0018] (4) The bidirectional force transmission spring realizes the bidirectional clutch function. When the motor is driven to the position, the spring can prevent the motor from stalling, thereby extending the service life of the helmet lock.

[0019] (5) The lock body uses the method of rotating the lock tongue to limit the position. The structure is simple. The entire mechanism only includes a motor and a gearbox. It is compact in size and reduces the number of failure points, thus improving reliability.

[0020] (6) The helmet has built-in sensors that transmit the wearing status to the backend in real time via Bluetooth. The system will promptly remind users who are not wearing helmets and guide them to develop the habit of wearing them. Attached Figure Description

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification.

[0037] Example 1

[0038] like Figures 1 to 8 As shown, a shared helmet basket device includes a helmet body 1, a basket 2, and a locking body 3. The helmet body 1 has grooves 101 on both sides. The basket 2 is provided with limiting ribs 201 at the positions corresponding to the grooves 101 to limit the helmet body 1 in a first direction. A vent 102 is provided on the front side of the helmet body 1. The locking body 3 rotates and extends into the vent 102 to limit the helmet body 1 in a second direction. With this design, the locking tongue extends through a rotating action and inserts into the front vent of the helmet. This multi-dimensional limiting achieves full locking of the helmet at low cost without any additional devices, ensuring the integrity of the helmet.

[0039] In addition, to ensure the safety of the helmet body 1, a basket lid is hinged to the basket 2 to protect the helmet body 1 inside from external damage.

[0040] In one embodiment, the lock body 3 includes a motor 301 and a latch 303. The latch 303 is mounted on an output shaft 306, and a half gear 307 is mounted on the output shaft 306. The motor 301 is connected to the half gear 307 through a transmission assembly 302 to drive the latch 303 to rotate in order to unlock and lock. That is, when the latch 303 rotates to extend into the vent hole 102, it locks; when the latch 303 rotates 90° away from the vent hole 102, it unlocks. In addition, in order to protect the internal components of the lock body 3, the lock body 3 also includes a lock shell 311. The entire lock body 3 can be bolted to the vegetable basket 2.

[0041] In one embodiment, such as Figure 5 and 6 As shown, the transmission assembly 302 includes a worm 3021, a worm wheel 3022, and a gear set. The worm 3021 meshes with the worm wheel 3022. The worm wheel 3022 meshes with a second gear 3024 via a first gear 3023. The second gear 3024 meshes with a half gear 307. The half gear 307 has three protrusions 309 at its bottom, and a clutch spring 304 is fitted onto each protrusion 309. Specifically, as shown... Figure 6 As shown, protrusions 309 are numbered 1, 2, and 3 from left to right. There are two clutch springs 304. The first spring is fitted onto protrusions 1 and 2 of 309, and the second spring is fitted onto protrusions 2 and 3 of 309. During unlocking and locking, the clutch springs 304 can be used to engage and disengage, thereby preventing the motor 301 from stalling. For example, when unlocking, the clutch springs 304 press the last tooth on the first side of the half gear 307 onto the first gear 3023 to engage and disengage. When locking, the clutch springs 304 press the last tooth on the second side of the half gear 307 onto the first gear 3023 to engage and disengage.

[0042] In one embodiment, the lock body 3 further includes a PCBA board 305, on which a micro switch 308 is provided, and a connector 310 for driving the micro switch 308 is installed on the output shaft 306. When locking, the connector 310 rotates to the position of the micro switch 308, presses it, and transmits the locking signal to the controller.

[0043] In one embodiment, the PCBA board 305 communicates with the controller via a CAN bus or a 485 bus, or is directly driven by the controller. These technologies are all mature existing technologies, and their communication principles will not be described in detail here.

[0044] In one embodiment, a wearing detection module 5 electrically connected to the controller is also included. The wearing detection module 5 includes a Bluetooth module and a sensor. Both the Bluetooth module and the sensor are built into the helmet body 1. The sensor is at least one of an infrared sensor, a human body sensor, and a triaxial force sensor, used to detect whether the user is wearing the helmet. When the helmet body 1 is in the unlocked state, the helmet body 1 communicates with the lock body 3 through the Bluetooth module and detects whether the helmet is being worn through the sensor. The wearing information is fed back to the lock body 3, and the lock body 3 then transmits it to the controller for real-time feedback on the wearing status.

[0045] In one embodiment, a helmet return detection module 6 electrically connected to the controller is also included. The helmet return detection module 6 is used to detect whether the helmet body 1 is returned to the basket 2. In this embodiment, the helmet return detection module 6 includes a magnetic switch 601 disposed on the PCBA board 305 and a magnet 103 built into the helmet body 1. After the helmet is returned, the magnetic switch 601 senses that the magnet 103 is in place and transmits a signal to the controller.

[0046] The specific working principle of the switch lock is as follows:

[0047] Upon receiving the helmet lock release command, motor 301 drives worm gear 3021 to rotate counterclockwise. Worm gear 3021 and worm wheel 3022 work together to drive the gear set to rotate, amplifying the torque. Output shaft 306 drives locking tongue 303 to rotate counterclockwise, and locking tongue 303 rotates out of the ventilation hole 102 at the front edge of helmet body 1, thereby releasing the restriction on helmet body 1 in the second direction. Since the half gear 307 on output shaft 306 only has partial teeth, when half gear 307 has completed its rotation, clutch spring 304 will press the last tooth on the first side of half gear 307 onto first gear 3023 to achieve disengagement, thereby ensuring that motor 301 will not stall, thus protecting the components on motor 301 and PCBA board 305. At the same time, when driving motor 301 to reverse the direction next time, the upper teeth can be engaged.

[0048] Upon receiving the helmet lock command, motor 301 drives worm gear 3021 to rotate clockwise. Worm gear 3021 and worm wheel 3022 work together to drive the gear set to rotate, amplifying the torque. Output shaft 306 drives locking tongue 303 to rotate clockwise. Locking tongue 303 moves into the ventilation hole 102 at the front edge of helmet body 1, thereby limiting the helmet body 1 in the second direction. At the same time, the protrusion 309 below connector 310 presses against micro switch 308, sending a locking signal to the controller. Half gear 307 on output shaft 306 only has partial teeth. When half gear 307 has completed its rotation, clutch spring 304 will press the last tooth on the second side of half gear 307 onto first gear 3023 to achieve disengagement, thereby ensuring that motor 301 will not stall, thus protecting the components on motor 301 and PCBA board 305. At the same time, when driving motor 301 to reverse, the upper teeth can be engaged.

[0049] Example 2

[0050] Unlike Embodiment 1, in this embodiment, the helmet detection module 6 includes a card reader built into the lock body 3 and an NFC card, IC card, or ID card built into the helmet body 1. The card reader reads the NFC card, IC card, or ID card and transmits the signal to the controller.

[0051] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
