DETAILED DESCRIPTION

[0063] The present invention is described below based on the following embodiments, but the present invention is not limited to these embodiments. In the detailed description of the present invention below, certain specific details are described in detail. Those skilled in the art can fully understand the present invention without these details. To avoid obscuring the essence of the present invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0064] Furthermore, persons of ordinary skill in the art will appreciate that the figures provided herein are for illustration purposes only and are not necessarily drawn to scale.

[0065] Unless the context clearly requires otherwise, words like “include”, “comprising” and the like throughout this application should be interpreted as including rather than exclusive or exhaustive; that is, as meaning “including but not limited to”.

[0066] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0067] Unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," and the like should be understood broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0068] With the promotion of green travel concepts, shared bicycles and electric vehicles are becoming increasingly popular short-distance travel options. To protect riders' safety, helmets are mandatory. In the event of an accident, helmets effectively protect the rider's head and prevent head injuries. To increase the use and safety of shared two-wheeled vehicles, each vehicle must be equipped with a helmet.

[0069] Taking shared electric bikes as an example, since electric bikes are shared, each user needs to lock the helmet with the bike after using it. When the next user uses the bike, they can unlock the helmet and bike to use the bike and helmet, which can effectively prevent the helmet from being lost.

[0070] Specifically, the electric vehicle includes a storage basket A, a helmet lock B and a helmet C. Figure 1-Figure 3As shown, the storage basket A has a confined space A1 formed to fit the outer side of the helmet C, ensuring that the helmet C does not shake when placed within the confined space A1 of the storage basket A. Specifically, the inner sidewall of the confined space A1 matches (i.e., has a similar shape to) the first side surface of the helmet C. The first side surface is the outer side surface of the helmet C near the edge. This first side surface is the maximum side surface formed by the helmet C, allowing the helmet C to fit within the confined space A1.

[0071] like Figure 2 As shown, the helmet lock B is fixed in the confined space A1, and a gap is formed between the helmet lock B and the side wall of the confined space A1, and the helmet lock B is smaller than the accommodating space inside the helmet. The gap is greater than or equal to the thickness of the corresponding position of the helmet C, so that the helmet C can be placed between the helmet lock B and the side wall of the confined space A1. At the same time, the arrangement of the helmet lock B and the confined space A1 ensures that the helmet C is always oriented downward and the front and rear positions of the helmet C are fixed, making it convenient for the user to put the helmet C in and out. The outer side of the helmet lock B is adapted to the side shape of the corresponding position of the helmet C, so that the shape of the gap formed between the helmet lock B and the confined space A1 is the same as the side shape of the helmet C, so that the helmet C can be quickly and accurately placed in the correct position, with an anti-foolproof positioning function.

[0072] After the helmet is locked, the helmet C always covers the helmet lock B downward, so that the helmet lock B is hidden in the storage basket A, preventing the helmet lock B from being stolen when the electric vehicle is stationary. The helmet C is placed downward, making it difficult for water and dust to enter the interior of the helmet C, thereby improving the dust and water resistance of the interior of the helmet C.

[0073] like Figure 2 and Figure 13 As shown, the two sides of the helmet C are respectively provided with locking grooves C1. When the helmet C is placed in the limited space A1, the locking pin B1 of the helmet lock B is arranged opposite to the locking grooves C1. Figure 3 and Figure 13 As shown, the lock pin B1 of the helmet lock B extends from the helmet lock B and extends into the corresponding lock slot C1, thereby locking the helmet C in the storage basket A.

[0074] Specifically, the helmet C is provided with an identity recognition chip, and the helmet lock B is provided with an identity sensing recognition circuit B2. Figure 12 As shown, the helmet and the electric bike are bound one-to-one. When a user scans the code to rent a bike, the server sends an unlock command to the identity sensing and recognition circuit B2 of the helmet lock B in the corresponding electric bike. The identity sensing and recognition circuit B2 activates the drive mechanism, causing the lock pin B1 to move out of the lock slot C1 and into the lock body, thereby unlocking the helmet C and the storage basket A, allowing the user to wear the helmet C while riding the electric bike.

[0075] When the user finishes their ride, they can send a return message to the server via a mobile app. Based on this return message, the server issues a locking command to the identity sensing circuit in helmet lock B inside the electric bike. Identity sensing circuit B2 senses the identity chip C3 in helmet C and determines whether helmet C has been placed in the corresponding position in storage basket A. Once helmet C has been positioned, circuit B2 activates the drive mechanism, causing locking pin B1 to extend from the lock body and into the corresponding lock slot C1, locking helmet C.

[0076] Furthermore, since the helmet C has a shared function, the helmet C is easily contaminated by repeated use, which reduces the comfort of the user. In order to keep the inside of the helmet C clean and to facilitate the cleaning of the helmet C, a waterproof lining C2 is provided on the inside of the helmet C. Figure 3 The waterproof lining C2 does not absorb water, which can prevent the user from contaminating the lining through sweat absorbed by the lining during wearing.

[0077] Example 1:

[0078] Figure 4-Figure 6 : is a schematic diagram of the internal structure of a helmet lock according to an embodiment of the present invention, Figure 7 Schematic diagram of the signal transmission relationship of the helmet lock according to the embodiment of the present invention. Figure 4 The figure shows the positional relationship between the various components of the base 31 when it is in the locked state. Figure 5 and Figure 6 The states of the lock pin 2 in the first position and the second position are shown respectively. Figure 4-Figure 7 As shown, the helmet lock device of this embodiment includes a lock housing 1, a lock pin 2, a drive mechanism 3, an elastic element 4, a lock pin motion sensor 5, an RFID reader 6, and a control circuit 7. The lock housing 1 has a lock hole 11 through which the lock pin 2 extends. The lock pin 2 is aligned with the lock hole 11 and can move along the lock hole 11. The drive mechanism 3 is connected to the lock pin 2 and includes a base 31, which is elastically connected to the lock pin 2 via the elastic element 4. The drive mechanism 3 drives the base 31 to perform linear motion between an unlocked position and a locked position, causing the lock pin 2 to move along the lock hole 11. The elastic element 4 is configured to maintain the lock pin 2's tendency to extend out of the lock hole 11, allowing the lock pin 2 to move relative to the base 31. When the base 31 is in the unlocked position, the lock pin 2 has a first position exposed in the lock hole 11 and a second position accommodated within the lock housing 1. The lock pin motion sensor 5 is used to detect the lock pin's rebound and generate a rebound signal, which indicates that the lock pin has moved to the second position. The control circuit 7 is connected to the lock pin action sensor 5 and the RFID reader 6. The RFID reader 6 is used to detect the RFID tag and send the detection result to the control circuit 7. The control circuit 7 determines the presence status of the helmet in response to the rebound signal and the detection result.

[0079] The lock pin action sensor 5 is used to detect the rebound action of the lock pin 2. The "rebound action" indicates that the lock pin 2 moves in the direction of the lock shell 1 relative to the base 31. Specifically, when the base is in the unlocked position, the "rebound action" indicates that the lock pin 2 moves from the first position to the second position. The setting position of the lock pin action sensor 5 should match the unlocked position of the base 31 and the second position of the lock pin 2, so that the lock pin action sensor 5 is triggered when the base 31 is in the unlocked position and the lock pin 2 moves to the second position, while the lock pin 2 rebounds when the base 31 is in the locked position or other positions and does not trigger the lock pin action sensor 5. When the lock pin action sensor 5 detects that the lock pin 2 moves to the second position, a rebound signal is sent to the control circuit 7. In response to the rebound signal, the control circuit 7 sends a start signal to the RFID reader 6, triggering the RFID reader 6 to start detecting the RFID tag. By triggering the activation of the RFID reader 6 according to the rebound action of the locking pin 2, the RFID reader 6 does not need to be kept in the activated state all the time, but is activated only when the presence state of the helmet may change, thereby saving power.

[0080] like Figure 4-Figure 6 As shown, the lock pin action sensor 5 can be set on the side of the base and the lock pin, and the lock pin 2 has a tentacle portion 23 protruding laterally, and the tentacle portion 23 is opposite to the lock pin action sensor 5. When the lock pin 2 moves to the second position, the tentacle portion 23 enters the detection range of the lock pin action sensor 5, triggering the lock pin action sensor 5 to generate a rebound signal.

[0081] Preferably, the helmet lock may further include a locking state sensor 8 for detecting the position of the base 31 and sending an unlocking position signal to the control circuit 7 when the base 31 reaches the unlocking position, and sending a locking position signal to the control circuit 7 when the base 31 reaches the locking position.

[0082] The aforementioned lock pin action sensor 5 and lock state sensor 8 can be any sensor capable of detecting the presence, distance, or motion of an object, such as an infrared distance sensor, a microwave distance sensor, a travel switch, a proximity switch, a micro switch, etc. Optionally, the lock pin action sensor 5 and lock state sensor 8 in this embodiment can be a proximity switch, which is relatively low in cost and has a long lifespan, facilitating maintenance of the helmet lock.

[0083] The control circuit 7 is also configured to send a stop signal to the drive mechanism 3 in response to the unlock position signal and / or the lock position signal, control the drive mechanism 3 to stop working, and make the base 31 stay in the unlock position or the lock position, so as to facilitate the control of the working state of the drive mechanism 3.

[0084] In at least one usage scenario, the helmet is provided with a radio frequency identification tag, which stores unique identification information. The radio frequency identification reader 6 is used to detect the radio frequency identification tag and read the information of the radio frequency identification tag.

[0085] Radio Frequency Identification (RFID) is a type of automatic identification technology that uses radio frequency (RF) for contactless, two-way data communication. It uses RF to read and write to recording media (electronic tags or RFID cards), thereby achieving target identification and data exchange. The basic principle of RFID is that after a tag enters a reader, it receives the RF signal emitted by the reader and uses the energy gained from the induced current to transmit the product information stored in the chip (passive tags). Alternatively, the tag actively transmits a signal of a certain frequency (active tags). The reader reads and decodes the information and sends it to a central information system for relevant data processing.

[0086] When the RFID tag enters the detection range of the RFID reader 6, the RFID reader 6 detects the RFID tag and sends the detection result to the control circuit 7. The control circuit 7 determines whether the correct helmet is near the helmet lock based on whether the detection result matches the predetermined unique identification information of the correct helmet.

[0087] Furthermore, in at least one usage scenario, the helmet is provided with a magnet, and the helmet lock further includes a Hall sensor 9 ( Figure 4-Figure 6 (not shown in the figure). A Hall sensor is a magnetic field sensor based on the Hall effect. Essentially, the Hall effect is the deflection of moving charged particles in a magnetic field due to the Lorentz force. When charged particles (electrons or holes) are confined in a solid material, this deflection results in the accumulation of positive and negative charges in a direction perpendicular to the current and magnetic field, forming an additional transverse electric field. The Hall voltage varies with the strength of the magnetic field: the stronger the field, the higher the voltage, and the weaker the field, the lower the voltage. Therefore, Hall sensors can be used to detect changes in magnetic fields.

[0088] The Hall sensor 9 is mounted within the lock housing 1 at a position that matches the magnet on the helmet. It detects changes in the magnetic field generated by the magnet on the helmet and generates a corresponding magnetic field change signal. When the magnet on the helmet enters the detection range of the Hall sensor 9 and the helmet gradually approaches the helmet lock, the Hall sensor 9 generates a magnetic field enhancement signal. The control circuit 7 determines that the helmet is approaching based on the magnetic field enhancement signal. When the magnetic field strength reaches a predetermined threshold, the control circuit 7 determines that the helmet has reached a predetermined position. As the helmet gradually moves away from the helmet lock, the magnetic field gradually weakens until it falls below the range of the Hall sensor 9. The Hall sensor 9 generates a magnetic field disappearance signal, and the control circuit 7 determines that the helmet has moved away from the predetermined position based on the magnetic field disappearance signal.

[0089] Those skilled in the art can shape the lock housing 1 into any shape that facilitates installation and connection to a helmet, depending on the needs of the actual application scenario. Optionally, the shape of the lock housing 1 can match the shape of the inner wall of the helmet to facilitate helmet positioning. The lock housing 1 defines a lock hole 11, the size of which is compatible with the size of the lock pin 2, allowing the lock pin 2 to smoothly extend and retract from the lock hole 11 while preventing dust or other debris from entering the lock housing 1 due to the oversized lock hole 11, thereby affecting the normal operation of the helmet lock.

[0090] The driving mechanism 3 includes a power device and a corresponding transmission device. The power device can be a motor, a cylinder, etc. The transmission device can include a reduction gear set, a worm gear, a gear rack, etc. The output component of the transmission device is fixedly connected to the base 31, and the output component can also be formed into one piece with the base 31. The power output by the driving mechanism 3 drives the base 31 to move linearly, thereby driving the lock pin 2 to extend and retract along the lock hole 11. For example, Figure 4-Figure 6 As shown, the power device of this embodiment is a motor, the output shaft of the motor is a worm, and the transmission device includes a reduction gear set and a rack. The worm and the rack are respectively engaged with the input side and output side of the reduction gear set for transmission. The rack is the output component of the transmission device, and the base 31 is formed as a whole with the rack. Thus, the driving mechanism 3 can drive the locking pin 2 to move in a straight line.

[0091] The lock pin 2 can be formed into any desired shape, such as a cylinder, prism, wedge, or other shape, specifically to match the shape of the lock slot provided on the helmet. For example, the lock pin 2 of this embodiment is substantially cylindrical. The lock pin 2 is aligned with the lock hole 11 to prevent the lock pin 2 from scraping against the sidewall of the lock hole 11 during extension and retraction, thereby affecting the normal operation of the helmet lock.

[0092] The lock pin 2 has a first end opposite to the lock hole 11 and a second end arranged in the lock shell 1. The base 31 moves between the unlocking position and the locking position. In the process of driving the lock pin 2 to move along the lock hole 11, the second end of the lock pin 2 is always in the lock shell 1 to prevent the lock pin 2 from falling off.

[0093] The first end of the locking pin 2 has a guide section 21 that gradually increases in size toward the second end. In other words, the guide section 21 gradually contracts from the side near the second end toward the direction away from the second end. The specific shape of the guide section 21 can be formed into a hemispherical, semi-ellipsoidal, conical, or other shapes. When a certain force is applied to the helmet in a direction perpendicular to the locking pin 2, the force forms a certain angle with the surface of the guide section 21, so that the force acting on the surface of the guide section 21 has a component in the direction of retraction of the locking pin 2 (i.e., pointing toward the second end of the locking pin 2), thereby pushing the locking pin 2 into the lock hole 11.

[0094] The elastic element 4 can be any component such as a spring, a spring sheet, or an elastic band that can exert an elastic force on the lock pin 2 in the direction of extending out of the lock hole 11. When the lock pin 2 is moved to the second position by an external force, the elastic force of the elastic element 4 can return the lock pin 2 to the first position and extend out of the lock hole 11 after the external force is removed.

[0095] The base 31 moves between a locked position and an unlocked position. When the base 31 moves to the locked position, the helmet lock is in a locked state, used to lock the helmet; when the base 31 moves to the unlocked position, the helmet lock is in an unlocked state, and the helmet can be separated from the helmet lock and taken out. Figure 4 As shown, when the base 31 moves to the locked position, the distance between the base 31 and the lock hole 11 is the shortest, so that the lock pin 2 extends a long distance, and the lock pin 2 extends into the lock slot of the helmet to lock the helmet. When the base 31 moves from the locked position to the unlocked position, it drives the lock pin 2 to gradually retract into the lock housing 1. Figure 5 and Figure 6 As shown, when the base 31 moves to the unlocking position, the distance between the base 31 and the lock hole 11 is the shortest.

[0096] When the base 31 is in the unlocked position, the lock pin 2 has a first position exposed in the lock hole 11 (refer to Figure 5 ) and the second position accommodated in the lock housing 1 (refer to Figure 6 Of course, when the gap between the lock hole 11 and the helmet is large, those skilled in the art may also, as needed, allow a portion of the lock pin 2 to remain exposed in the lock hole 11 when in the second position. In this case, the length of the lock pin 2 exposed in the lock hole 11 when in the second position is shorter than the length of the lock pin 2 exposed in the lock hole 11 when in the first position.

[0097] Reference Figure 4 and Figure 5 When the lock pin 2 is in the first position, the length of the lock pin 2 exposed from the lock hole 11 is shorter than the length of the lock pin 2 exposed from the lock hole 11 when the base 31 moves to the locked position. Only a shorter part of the lock pin 2 is exposed, so that the guide end is at the edge of the lock slot on the helmet, which can play a certain fixing function for the helmet, preventing the helmet from being separated from the helmet lock due to a small shake and falling or colliding with other objects after the helmet lock is unlocked.

[0098] When the user needs to remove the helmet, they simply pull the helmet with a certain amount of force, causing the sidewalls of the helmet's lock slot to push the guide section 21 upward from the side, exerting a force. This force acts on the surface of the guide section 21, creating a component in the direction of the lock pin 2's retraction, causing it to retract into the keyhole 11 (in this process, the elastic element 4 is deformed by the force). When the lock pin 2 moves to the second position, it is accommodated within the lock housing 1, completely disengaging the lock slot, allowing the helmet to be removed. To facilitate helmet removal, the edge of the helmet's lock slot can be designed as an arc. When the helmet is removed, the elastic element 4 forces the lock pin 2 to move to the first position. To connect the helmet to the helmet lock, the edge of the helmet pushes the guide end upward from the side, causing the lock pin 2 to move to the second position and retract. When the helmet's lock slot aligns with the lock pin 2, the lock pin 2 pops out to the first position, securing the helmet. At this point, the helmet lock can be controlled to close or simply remain unlocked to temporarily secure the helmet.

[0099] Furthermore, the provision of elastic element 4 allows for adaptability to helmets with varying lock slot depths and sizes. When the first end of lock pin 2 contacts the bottom of the lock slot, lock pin 2 rebounds a certain distance relative to base 31, preventing base 31 from further pushing lock pin 2 outward and damaging the helmet. Furthermore, a stopper 12 can be provided within lock housing 1, opposing base 31 to limit the range of motion of base 31. When base 31 moves to the locked position, it abuts against stopper 12, preventing base 31 and lock pin 2 from further extending outward.

[0100] To achieve the above functions, those skilled in the art can design the structure of the base 31, elastic element 4, and lock pin 2, as well as the connection method therebetween, as needed. A feasible embodiment is described below, but it should be understood that the structure of the base 31, elastic element 4, and lock pin 2, as well as the connection method therebetween, are not limited to this.

[0101] Figure 8 for Figure 4 The local enlarged diagram of X in the figure. Figure 4-Figure 6 as well as Figure 8As shown, the base 31 forms a hollow accommodating space with a first sidewall 311 and a second sidewall 312 disposed opposite each other. The first sidewall 311 and the second sidewall 312 can both be perpendicular to the lock pin 2. The second end of the lock pin 2 is disposed within the accommodating space, opposite the first sidewall 311. The second sidewall 312 has an opening 312a, through which the lock pin 2 passes, with the first end of the lock pin 2 positioned outside the accommodating space. The size of the opening 312a matches the size of the middle portion of the lock pin 2. A certain gap exists between the lock pin 2 and the opening 312a, allowing the lock pin 2 to smoothly extend and retract along the opening 312a while preventing the lock pin 2 from easily wobbling due to excessive gap. A stopper 22 is formed at the second end of the lock pin 2, opposite the second sidewall 312. The stopper 22 is larger than the opening 312a to prevent the lock pin 2 from slipping out of the accommodating space.

[0102] The distance between the first side wall 311 and the second side wall 312 is greater than the length of the limit platform. The elastic element 4 connects the first side wall 311 and the second end of the lock pin 2 so that there is a certain gap between the second end of the lock pin 2 and the first side wall 311, and the lock pin 2 can move within the accommodating space. For example, the length of the elastic element 4 can be set so that when the lock pin 2 is in the first position, the limit platform 22 and the second side wall 312 abut against each other, which facilitates controlling the relative position between the lock pin 2 and the base 31. When the lock pin 2 moves from the first position to the second position, the elastic element 4 is compressed. When the driving mechanism 3 causes the base 31 to push the lock pin 2 to move out of the lock hole 11, the base 31 transmits the driving force to the elastic element 4 through the first side wall 311, and the elastic element 4 causes the lock pin 2 to maintain a certain relative position with the base 31 and move outward.

[0103] Preferably, the base 31 has a limiting component for limiting the range of movement of the lock pin 2 in the accommodating space. When the base 31 is in the unlocked position, specifically, the limiting component is used to limit the movement of the lock pin 2 between the first position and the second position. In an optional embodiment, the limiting component is a limiting column 313, the limiting column 313 is fixed to the first side wall 311, the elastic element 4 is a spring, and the elastic element 4 is placed on the outer periphery of the limiting column 313 and abuts between the first side wall 311 and the second end of the limiting pin. When the lock pin 2 moves to the second position, the second end of the lock pin 2 abuts the limiting column 313. In other words, the range of movement of the lock pin 2 relative to the base 31 can be jointly limited by the first side wall 311 and the limiting column 313. Providing the limiting column 313 can also prevent the elastic element 4 from shifting or falling out.

[0104] The helmet lock can be provided with one or more locking pins 2 as needed, corresponding to one or more locking slots on the helmet. Figure 4-Figure 6As shown, the lock housing 1 has two lock holes 11 and two corresponding lock pins 2 arranged in opposite directions. Two symmetrical lock slots can be set on both sides of the helmet, and the two lock pins 2 are symmetrically arranged. The driving mechanism 3 drives the two lock pins 2 to move in opposite directions, and simultaneously extend or retract into the lock holes 11 to lock or unlock the helmet. The distance between the two lock pins 2 is adapted to the width of the helmet, so that when the helmet lock is in the locked state (i.e., when the base 31 is in the locked position), both lock pins 2 extend into the corresponding lock slots on the helmet to lock. By providing two symmetrical lock pins 2, the helmet can be better fixed and the anti-theft effect can be improved.

[0105] Furthermore, outwardly extending protrusions 13 are formed on both sides of the lock housing 1, and the lock hole 11 is provided on the end surface of the protrusion 13. The user can determine the position of the lock pin 2 through the protrusion 13, making it easier for the user to align the lock slot of the helmet with the lock pin 2, and also facilitating positioning when the helmet lock is installed in a predetermined position.

[0106] The helmet lock may also include a communication device electrically connected to the control circuit 7 for wired and / or wireless communication. The communication device receives unlocking signals and / or locking signals, and may also transmit signals generated by the helmet lock related to the helmet's presence or locked state, such as unlocking and locking signals. The unlocking and / or locking signals may originate from a server, a user terminal, or other general or non-standard electronic device with communication capabilities. The control circuit 7 controls the drive mechanism 3 to unlock in response to the unlocking signal and to lock in response to the locking signal.

[0107] A helmet lock according to an embodiment of the present invention includes a lock housing, a lock pin, a drive mechanism, an elastic element, a lock pin motion sensor, an RFID reader, and a control circuit. The lock housing has a lock hole through which the lock pin extends, and the lock pin is aligned with the lock hole. The drive mechanism is connected to the lock pin and includes a base. The drive mechanism drives the base between an unlocked position and a locked position, causing the lock pin to move along the lock hole. The elastic element maintains the lock pin's tendency to extend out of the lock hole, such that when the base is in the unlocked position, the lock pin has a first position exposed from the lock hole and a second position housed within the lock housing. The lock pin motion sensor detects the lock pin's rebound and generates a rebound signal, indicating that the lock pin has moved to the second position. The control circuit is connected to the lock pin motion sensor and the RFID reader, and determines the presence of a helmet in response to the rebound signal and the detection result of the RFID reader. Thus, the helmet lock according to an embodiment of the present invention can determine the presence of a helmet, facilitate helmet management, and achieve effective theft prevention.

[0108] Example 2:

[0109] A helmet lock can be used in vehicles, storage cabinets, or other devices to lock a helmet. The helmet lock includes a lock pin, a lock housing with a lock hole, and a drive mechanism that drives the lock pin to extend and retract along the lock hole. The helmet lock control method provided in an embodiment of the present invention is used to control the helmet lock. The helmet lock can be the helmet lock described in at least some embodiments of Example 1, or it can be other corresponding helmet locks capable of executing this method. The method can be implemented by an external control device connected to the helmet lock or a control circuit integrated into the helmet lock. The external control device or internal control circuit can be a general-purpose data processing device.

[0110] Figure 9 FIG. 1 is a flow chart of the helmet lock control method of this embodiment. Figure 9 As shown, the helmet lock control method includes the following steps S100 to S200.

[0111] Step S100: In response to receiving an unlocking instruction, the lock pin is controlled to retract and enter an unlocking state.

[0112] The unlock command can come from a server, terminal, or other compatible electronic device. Upon receiving the unlock command, the control circuit controls the drive mechanism to retract the locking pin to a predetermined position, putting the lock into the unlocked state. When the lock is in the unlocked state, the locking pin is partially exposed from the keyhole, maintaining a certain connection with the helmet.

[0113] Step S200: Detecting the rebound signal and the radio frequency identification tag to determine the presence status of the helmet.

[0114] The helmet is equipped with an RFID tag that stores a unique identifier for the helmet. The helmet lock detects the rebound signal and the RFID tag and, based on the rebound signal and the RFID tag, determines whether the helmet is in a predetermined position. This predetermined position is typically where the lock pin of the helmet, which connects to the lock pin, is aligned with the lock pin of the helmet lock. The rebound signal indicates that the lock pin is in a rebound state. When the lock pin is in the rebound state, it is accommodated in the lock housing. Figure 10 is a flow chart of a method of step S200 of this embodiment. Specifically, Figure 10 As shown, step S200 may include the following steps S210, S2a, S220 and S230.

[0115] Step S210: In response to detecting a rebound signal after entering the unlocked state, triggering detection of the radio frequency identification tag.

[0116] After the lock enters the unlocked state and detects the rebound signal, the RFID tag is detected. The control circuit determines whether the correct RFID tag is detected based on the detection result and determines the presence of the helmet.

[0117] Step S2a: Determine whether the RFID tag is detected.

[0118] Depending on the detection result, there are two situations, namely, the situation where the correct RFID tag is not detected and the situation where the correct RFID tag is detected. If the correct RFID tag is not detected, the following step S220 is executed; if the correct RFID tag is detected, the following step S230 is executed.

[0119] Step S220: In response to not detecting the RFID tag, determining that the current helmet presence status is removed.

[0120] Step S230: In response to detecting the RFID tag, determining that the current helmet presence status is helmet presence.

[0121] Figure 11 is another method flow chart of step S200 of this embodiment, as shown in FIG. Figure 11 As shown, in at least some implementations of this embodiment, step S230 may be replaced by the following step S240. When the judgment result of step S2a is "yes", the following step S2b is also included.

[0122] Step S2b: Determine whether a magnetic field enhancement signal is detected.

[0123] The helmet lock can be equipped with a Hall effect sensor. The helmet has a magnet, and the Hall effect sensor detects changes in the magnetic field. When the Hall effect sensor detects that the magnetic field gradually increases and reaches a predetermined threshold, it generates a corresponding magnetic field enhancement signal. If the magnetic field enhancement signal is detected, the following step S240 is executed. Otherwise, the process returns to step S210 to recheck the RFID tag, or determines that the helmet is not currently present, or executes other steps as needed.

[0124] Step S240: In response to detecting the radio frequency identification tag and the magnetic field enhancement signal, determining that the current helmet presence state is helmet presence.

[0125] When a correct RFID tag is detected and the Hall sensor generates a magnetic field enhancement signal, the control circuit determines that the helmet is at a predetermined position and determines that the current presence state of the helmet is the helmet present.

[0126] like Figure 9 As shown, the helmet lock control method may further include the following step S300:

[0127] Step S300: In response to receiving the locking instruction and the current helmet presence state being the helmet presence, controlling the lock pin to extend and enter the locking state.

[0128] The locking instruction can come from a server, terminal, or other compatible electronic device. Upon receiving the locking instruction and if the current helmet presence status determined in step S200 is helmet present, the control circuit controls the drive mechanism to extend the lock pin and position it with the lock hole, placing the lock in a locked state. When the lock is in the locked state, the length of the lock pin protruding from the lock hole is greater than when the lock is in the unlocked state, enabling secure locking with the lock slot of the helmet.

[0129] It should be understood that the helmet lock control method of the embodiment of the present invention does not include only the steps described above. Those skilled in the art may make adjustments based on actual needs, adding or deleting certain steps. For example, after step S200, the method may further include a step of sending the determined current helmet presence status; for another example, step S300 may be deleted.

[0130] It should be understood that each process in the helmet lock control method of the embodiment of the present invention can be implemented by computer program instructions. These computer program instructions can be stored in a computer readable memory that can guide a computer or other programmable data processing device to operate in a specific manner, so that the instructions stored in the computer readable memory produce a product including an instruction device, which implements the process Figure 1 A function specified in a process or multiple processes.

[0131] These computer program instructions can also be provided to a processor of a general-purpose computer, a special-purpose computer, an embedded processor, or other programmable data processing device to produce a machine, so that the instructions executed by the processor of the computer or other programmable data processing device produce the instructions for implementing the process Figure 1 A device that specifies functions in a process or multiple processes.

[0132] Example 3:

[0133] The helmet lock in Example 1 can be installed anywhere, depending on the intended use, such as on a tabletop, wall, vehicle, or other location where a helmet needs to be locked. Alternatively, the helmet lock can be incorporated into a storage container. The storage container can be dedicated to helmets, or it can be used to store helmets and other items. Storage containers include, but are not limited to, boxes with lids, baskets, storage baskets, closets, cabinets, and the like. Generally, the shape of the storage container is relatively fixed, making it easier to install and use the helmet lock.

[0134] The storage container includes a container body and the helmet lock assembly of Example 1. The helmet lock assembly is secured within the container body, with a predetermined gap formed between the locking pin and the sidewall of the container body to facilitate placement of a helmet within the container body and align the helmet's locking slot with the locking pin of the helmet lock assembly. Preferably, the gap between the helmet and the sidewall of the container body is small after placement, thereby better preventing the helmet from shaking.

[0135] Example 4:

[0136] The helmet lock in Example 1 can be used in helmet storage spaces, helmet transport equipment, and vehicles. Alternatively, the helmet lock can be used in vehicles. Furthermore, the helmet lock can be used in two-wheeled vehicles. These two-wheeled vehicles can be powered by human power, electricity, an internal combustion engine, a hybrid powertrain, or other means, including but not limited to bicycles, electric vehicles, motorcycles, and scooters.

[0137] A two-wheeled vehicle includes a vehicle body, a storage basket, and a helmet lock. The storage basket is connected to the vehicle body and can be located at the front of the vehicle, below the seat, behind the seat, or in other convenient locations for securing and user use. When the helmet lock is engaged but the user has not removed the helmet, a locking pin temporarily secures the helmet. This prevents the helmet from shaking in the storage basket due to bumps and other conditions while riding the two-wheeled vehicle, potentially colliding with the basket's inner walls and causing damage, effectively extending the helmet's service life.

[0138] In the application scenario of shared two-wheeled vehicles, setting the helmet lock in Example 1 can facilitate the determination of the return status of the helmet when the user returns the vehicle, thereby reducing the risk of the helmet being stolen.

[0139] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
