[0028] Reference Figures 1-14 This utility model provides a helmet lock 100 for locking a helmet 200. In some applications, the helmet lock 100 can be installed on electric bicycles, bicycles, or other vehicles to secure the helmet lock 100 to the vehicle. When installed on a vehicle, the helmet lock 100 can be mounted in any convenient location for attaching the helmet 200, such as on the frame, seat, rack, or other locations.

[0029] In another aspect of this utility model embodiment, a helmet locking assembly is also disclosed. Referring to Figure 2, the helmet locking assembly includes a helmet 200 that can be locked in conjunction with a helmet lock 100. In this utility model embodiment, the helmet 200 includes a helmet body 201, helmet straps 202, and buckles 203. The helmet body 201 is worn on the user's head. The helmet 200 may have helmet straps 202 on its left and right sides respectively. The helmet 200 may also include a socket that can be plugged into the buckle 203. One end of one helmet strap 202 is connected to the helmet body 201, and the other end is connected to the buckle 203; one end of the other helmet strap 202 is connected to the helmet body 201, and the other end is connected to the socket. When the user wears the helmet 200, the buckle 203 and the socket can be plugged in to fix the helmet 200 to the user's head. The helmet lock 100 of this embodiment utilizes a buckle 203 on the helmet 200 to lock the helmet 200, eliminating the need for a lock hole or other additional locking structure on the helmet 200. This reduces the manufacturing difficulty of the helmet 200 and ensures its lightweight and strength. The surface of the buckle 203 has at least one toothed groove 206. Preferably, the surface of the buckle 203 has multiple toothed grooves 206 arranged along a first direction X1. The socket can connect to the buckle 203 by engaging with the toothed grooves 206. Optionally, the buckle 203 may include a base 204 and an insertion portion 205, wherein the toothed groove 206 is disposed in the insertion portion 205, and the base 204 is used to connect with the helmet strap 202. When the buckle 203 is connected to the socket, the insertion portion 205 is inserted into the socket, while the base 204 may protrude outside the socket. Preferably, the two opposite surfaces of the buckle 203 each have a toothed groove 206, and the toothed grooves 206 on both sides of the buckle 203 can be symmetrically arranged, so that the buckle 203 can be inserted on both sides, which is convenient for the user.

[0030] Figures 3-17 The structure of the helmet lock 100 is shown, wherein Figure 6 and Figure 7 The cross-sectional position is Figure 4 Plane AA in the diagram. (Refer to...) Figures 3-8 The helmet lock 100 includes a lock housing 10, a latch 20, and a first elastic element 30. The lock housing 10 has an opening 11 for inserting a buckle 203 on the helmet 200 and a channel 12 communicating with the opening 11, the channel 12 extending along a first direction X1. In this embodiment of the invention, the first direction X1 is the insertion and removal direction of the buckle 203 in the channel 12.

[0031] The lock housing 10 includes a front housing 13 and a rear housing 14, with the rear housing 14 connected to the front housing 13, forming a cavity to accommodate the locking tongue 20, the unlocking module 40, the control circuit 50, and other components of the helmet lock 100. The front housing 13 and the rear housing 14 can be connected by bolts, snap-fit ​​connections, adhesive bonding, or other methods. In this embodiment, an opening 11 is provided on the front housing 13.

[0032] A latch 20 is located on one side of the channel 12. The latch 20 includes a locking part 21 and an unlocking part 22. The locking part 21 is rotatably connected to the lock housing 10. For example, the locking part 21 can be connected to the lock housing 10 via a pivot 23. The locking part 21 has one or more teeth 211 corresponding to the grooves 206 on the buckle 203. The latch 20 rotates relative to the lock housing 10 to have a locked position and an unlocked position. When the latch 20 is in the locked position, the locking part 21 is inside the channel 12. When the latch 20 is in the unlocked position, the locking part 21 is out of the channel 12. A first elastic member 30 elastically connects the latch 20 to the lock housing 10 and holds the latch 20 in the locked position. In this embodiment, the first elastic member 30 can be a torsion spring. When the buckle 203 is inserted into the channel 12, the locking part 21 contacts the surface of the insertion part 205, and the teeth 211 of the latch 20 can engage with the grooves 206. The locking tooth 211 can be designed as a helical tooth. Under the action of the first elastic member 30, the locking tooth 211 of the locking tongue 20 and the buckle 203 form a self-locking structure, so that the buckle 203 can continue to be inserted into the channel 12. When the buckle 203 is pulled outward, the locking tooth 211 abuts against the side wall of the tooth groove 206 and prevents the buckle 203 from being pulled out.

[0033] The unlocking part 22 of the locking tongue 20 is located on the side of the locking part 21 away from the channel 12. The helmet lock 100 also includes an unlocking module 40 and a control circuit 50. The control circuit 50 can control the unlocking module 40 to move the unlocking part 22, thereby causing the locking part 21 to exit the channel 12 and releasing the lock on the buckle 203. In this embodiment, the unlocking module 40 includes a drive device 41, a transmission mechanism 42, and an actuator 43. The control circuit 50 is electrically connected to the drive device 41. When the control circuit 50 receives an unlocking command, it controls the drive device 41 to work. The drive device 41 drives the actuator 43 to move relative to the unlocking part 22 through the transmission mechanism 42. The actuator 43 drives the unlocking part 22 to move so that the locking tongue 20 moves from the locked position to the unlocked position. The unlocking command can be sent to the control circuit 50 by a vehicle controller, server, or user terminal via wired or wireless means. In one embodiment, refer to Figure 3 and Figure 5 The drive unit 41 includes a motor, the output shaft of which has a worm gear 411. The transmission mechanism 42 includes an input gear 421, an output gear 422, and at least one intermediate gear 423 connected between the input gear 421 and the output gear 422. The actuator 43 includes a rack 431. The worm gear 411 meshes with the input gear 421, and the output gear 422 meshes with the rack 431. Thus, the rotation of the motor can be converted into linear motion of the actuator 43 through the transmission mechanism 42. The actuator 43 can actuate the unlocking part 22 to rotate around the rotating shaft 23, overcoming the spring force of the torsion spring and moving the locking part 21 away from the channel 12.

[0034] In some embodiments, refer to Figure 3 , Figures 6-7 The unlocking part 22 includes a connecting arm 221 and a roller 222. The connecting arm 221 is connected to the locking part 21, and the roller 222 is rotatably connected to the connecting arm 221 and located on the movement path of the actuator 43. The actuator 43 has an inclined surface 432 on the side opposite to the roller 222, and the inclined surface 432 contacts the roller 222. Optionally, the actuator 43 moves linearly between the third position and the fourth position along the first direction X1, and the inclined surface 432 is inclined relative to the first direction X1. When the driving device 41 drives the actuator 43 to move linearly through the transmission mechanism 42, the roller 222 rolls along the inclined surface 432, and at the same time, the position of the roller 222 is also lifted along the inclined surface 432. The roller 222 drives the locking part 21 away from the channel 12 through the connecting arm 221. When the actuator 43 is in the third position, refer to Figure 6 The actuator 43 pushes up the roller 222, causing the bolt 20 to be in the unlocked position; when the actuator 43 is in the fourth position, refer to Figure 7 and Figure 15The actuator 43 is in a lower position, and the latch 20 is held in the locked position by the action of the first elastic member 30. Thus, the position of the actuator 43 is related to the position of the latch 20.

[0035] In one embodiment, refer to Figures 6-7 as well as Figures 12-14 The locking tongue 20 also includes a rotating shaft 23. The locking part 21 is rotatably connected to the lock housing 10 via the rotating shaft 23. The front housing 13 has two spaced-apart opposing shaft positioning plates 131, and the locking part 21 is located between the two shaft positioning plates 131. The shaft positioning plates 131 have shaft positioning grooves 1311. The two ends of the rotating shaft 23 are respectively located in the corresponding shaft positioning grooves 1311. The shaft positioning plates 131 are open on the side facing the rear housing 14, allowing the rotating shaft 23 to be inserted into the shaft positioning grooves 1311 from the rear to the front. The rear housing 14 has a first baffle 141, the position of which corresponds to the shaft positioning grooves 1311 and the rotating shaft 23. When the rear housing 14 is connected to the front housing 13, the first baffle 141 is inserted into the shaft positioning grooves 1311 to press the rotating shaft 23 against the bottom of the shaft positioning grooves 1311 for fixation.

[0036] In some embodiments, refer to Figure 3 , Figures 5-11 The helmet lock 100 also includes an ejection mechanism 60 for ejecting the buckle 203 from the channel 12 upon unlocking. The ejection mechanism 60 is resiliently connected to the lock housing 10 and movable along the channel 12 between a first position and a second position. (See reference...) Figure 6 When the ejector mechanism 60 is in the first position, the ejector mechanism 60 approaches and at least partially blocks the opening 11; see reference. Figure 7 and Figure 8 When the pop-out mechanism 60 is in the second position, it is away from the opening 11. When the buckle 203 is inserted into the channel 12, the bottom of the buckle 203 pushes the pop-out mechanism 60 from the first position to the second position; and when the helmet lock 100 is unlocked, the pop-out mechanism 60 moves from the second position to the first position, pushing the buckle 203 out of the channel 12 and blocking the opening 11.

[0037] In some embodiments, the pop-out mechanism 60 includes a base 61, a limiting block 62, and a second elastic member 63. The base 61 has a main body 611 and a top plate 612, wherein the top plate 612 is disposed on the side of the main body 611 near the opening 11 and opposite to the opening 11. The shape and size of the top plate 612 are designed to be larger than the opening 11, such as... Figure 6 As shown, when the ejection mechanism 60 is in the first position, the top plate 612 can block the opening 11 to prevent debris from entering the helmet lock 100. (See reference...) Figure 9 and Figure 10The main body 611 has a first mounting hole 6111. The first mounting hole 6111 has a first sidewall 6112 and a second sidewall 6113 disposed opposite to each other along a first direction X1, wherein the second sidewall 6113 is away from the opening 11 relative to the first sidewall 6112. A limiting block 62 passes through the first mounting hole 6111 and partially extends out of the first mounting hole 6111 along a second direction X2 before connecting with the lock housing 10. The second direction X2 is not parallel to the first direction X1; for example, the second direction X2 can be perpendicular to the first direction X1. The lock housing 10 has a limiting plate 15. The limiting block 62 is fixed relative to the limiting plate 15. A second elastic member 63 is disposed in the first mounting hole 6111 and between the first sidewall 6112 and the limiting block 62, realizing an elastic connection between the base 61 and the lock housing 10. The first mounting hole 6111 is open in the second direction X2 to facilitate the insertion of the second elastic member 63 and the limiting block 62 into the first mounting hole 6111.

[0038] The second elastic element 63 can be a coil spring, a gas spring, a spring sheet, or other elastic device that can provide elastic force. In this embodiment, the second elastic element 63 is a coil spring. When the buckle 203 is inserted into the channel 12 and abuts against the top plate 612, and the pop-out mechanism 60 moves from the first position to the second position, the second elastic element 63 located between the first side wall 6112 and the limiting block 62 is compressed. The locking teeth 211 of the latch 20 engage with the tooth groove 206 of the buckle 203. The first elastic element 30 maintains the connection between the locking teeth 211 and the tooth groove 206, preventing the buckle 203 from coming out and keeping the second elastic element 63 in a compressed state. When the helmet lock 100 is unlocked, the latch 20 moves away from the buckle 203. Under the elastic force of the second elastic element 63, the base 61 pushes the buckle 203 out of the channel 12.

[0039] In some embodiments, refer to Figure 5 , Figure 8 and Figure 11 The limiting plate 15 has a first limiting groove 151. The limiting block 62 passes through the first mounting hole 6111 along the second direction X2 and is inserted into the first limiting groove 151 to fix the limiting block 62. The first limiting groove 151 can pass through along the second direction X2. In this embodiment, the second direction X2 is perpendicular to the first direction X1. In one embodiment, there are two limiting plates 15, which are arranged opposite each other at intervals along the second direction X2. A guide groove 16 extending along the first direction X1 is formed between the two limiting plates 15. The pop-out mechanism 60 is at least partially disposed in the guide groove 16. For example, the main body 611 can be slidably disposed in the guide groove 16 to ensure the stability of the pop-out mechanism 60 moving along the first direction X1. Optionally, as Figure 5 and Figure 8As shown, the limiting plate 15 has a first limiting platform 153 at one end near the opening 11. The first limiting platform 153 is opposite to the top plate 612. When the pop-out mechanism 60 moves to the second position, the first limiting platform 153 can abut against the top plate 612 to limit the movement range of the pop-out mechanism 60.

[0040] In one embodiment, the limiting block 62 includes a base plate 621 and two locking arms 622. Both ends of the base plate 621 extend through the first mounting hole 6111 along the second direction X2 and reach both sides of the main body 611, respectively, and are inserted into the first limiting groove 151 on a corresponding limiting plate 15. Each limiting plate 15 also has a second limiting groove 152, and the two second limiting grooves 152 of the two limiting plates 15 are spaced apart. The two locking arms 622 are located at both ends of the base plate 621 and extend in a direction intersecting the second direction X2 (e.g., see reference 1). Figure 8 and Figure 11 The locking arm 622 can extend along the first direction X1 away from the opening 11, and each locking arm 622 is disposed in a corresponding second limiting groove 152. Optionally, the opening of the second limiting groove 152 and the opening of the first limiting groove 151 are disposed on the same side of the limiting plate 15, so as to facilitate the connection between the limiting block 62 and the first limiting groove 151 and the second limiting groove 152.

[0041] In this embodiment of the invention, the helmet lock 100 further includes a position detection switch 70. The position detection switch 70 is electrically connected to the control circuit 50 and is used to assist in confirming the locking state of the helmet lock 100 on the buckle 203.

[0042] In some embodiments, the pop-out mechanism 60 can be used as a triggering component for the position detection switch 70. The pop-out mechanism 60 also includes a trigger block 64, which is connected to the base 61 and disposed opposite to the position detection switch 70. When the buckle 203 is inserted into place, the pop-out mechanism 60 moves to the second position, and the trigger block 64 triggers the position detection switch 70 to generate a position signal.

[0043] In some embodiments, the main body 611 further includes a second mounting hole 6114, which is located at the end of the first mounting hole 6111 away from the opening 11. The second mounting hole 6114 has a third sidewall 6115 and a fourth sidewall 6116 disposed opposite each other in a first direction X1, wherein the fourth sidewall 6116 is away from the opening 11 relative to the third sidewall 6115. The trigger block 64 has a limiting end 641 and a trigger end 642 disposed opposite each other, wherein the limiting end 641 is located in the second mounting hole 6114, and the fourth sidewall 6116 has a through hole 6117 extending along the first direction X1. The trigger end 642 extends out of the through hole 6117 and is disposed opposite to the position detection switch 70. The limiting end 641 may form a stepped structure to abut against the fourth sidewall 6116 to prevent the limiting end 641 from coming out of the through hole 6117. The pop-out mechanism 60 also includes a third elastic element 65, which is disposed in the second mounting hole 6114 and between the limiting end 641 and the third sidewall 6115. The third elastic element 65 can be compressed along the first direction X1. When the trigger end 642 contacts the position detection switch 70, the third elastic element 65 can act as an elastic buffer to prevent the trigger block 64 from making hard contact with the position detection switch 70 and generating excessive impact force that could damage the position detection switch 70. The third elastic element 65 can be a helical spring, a rubber block, a spring sheet, or other elastic device that can provide elastic force. In this embodiment, the third elastic element 65 can be a helical spring. The third sidewall 6115 and the side of the limiting end 641 opposite to the third sidewall 6115 can be respectively provided with protruding positioning posts. The two ends of the third elastic element 65 can be sleeved on the positioning posts to achieve positioning and prevent the third elastic element 65 from coming out of the second mounting hole 6114. The second mounting hole 6114 and the through hole 6117 have openings in the lateral direction that are not parallel to the first direction X1, through which the third elastic element 65 and the trigger block 64 can be inserted.

[0044] In another embodiment, the state of the unlocking module 40 can be detected by the position detection switch 70. Since the position of the actuator 43 is associated with the position of the latch 20, the position of the latch 20 can also be confirmed by detecting the position of the actuator 43, thereby assisting in confirming the state of the helmet lock 100. (Refer to...) Figure 15 and Figure 16 The actuator 43 has a trigger arm 433 on its side, and the position detection switch 70 is positioned opposite the end face of the trigger arm 433. For example... Figure 15 and Figure 16As shown, when the actuator 43 is in the fourth position, the trigger arm 433 triggers the position detection switch 70. Due to the elasticity of the first elastic element 30, the latch 20 remains in the locked position. In one embodiment, after the unlocking module 40 performs unlocking and the buckle 203 is moved out of the channel 12, the drive device 41 can drive the actuator 43 from the third position back to the fourth position through the transmission mechanism 42, causing the latch 20 to return from the unlocked position to the locked position. When the actuator 43 returns to the fourth position, the trigger arm 433 triggers the position detection switch 70, and the control circuit 50 controls the drive mechanism to stop.

[0045] Furthermore, in some embodiments, reference is made to Figure 6 and Figure 7 A magnetic element 207 can be installed on the buckle 203 of the helmet 200, and a magnetic detector 80 is also installed on the helmet lock 100. The magnetic detector 80 is electrically connected to the control circuit 50. When the buckle 203 is inserted into place, the magnetic detector 80 detects the magnetic element 207 on the buckle 203. Therefore, when the position detection switch 70 is triggered to generate a position signal, and the magnetic detector 80 detects the magnetic element 207 on the buckle 203, it indicates that a matching buckle 203 has been inserted into the helmet lock 100 and is properly engaged. Thus, the control circuit 50 can determine that the helmet 200 has been returned. This setting can effectively prevent false alarms and prevent users from using other foreign objects inserted into the channel 12 to impersonate the buckle 203 of the helmet 200 for a false return. In this embodiment, the magnetic detector 80 can be a Hall sensor or a reed switch, and the magnetic element 207 can be a magnet. Based on the signal from the magnetic detector 80 and the signal from the position detection switch 70, the locking state of the buckle 203 can be accurately determined. When the magnetic detector 80 detects the magnetic component 207 and the position detection switch 70 is triggered, it indicates that the buckle 203 has been locked in place.

[0046] The installation position of the magnetic detector 80 in the helmet lock 100 matches the position of the magnetic element 207 on the buckle 203 when it is inserted into the channel 12, to achieve a more accurate recognition effect. When the buckle 203 is inserted into the helmet lock 100, the magnetic element 207 and the magnetic detector 80 are close together and their relative positions are fixed, to ensure the accuracy of the detection result of the magnetic detector 80 and to prevent the user from interfering with the magnetic detector 80 by bringing a magnet close to the helmet lock 100, causing the helmet lock 100 to misjudge the locking status of the helmet 200. In one embodiment, such as Figure 6 and Figure 7 As shown, the magnetic component 207 is disposed in the base 204 of the snap fastener 203. When the insertion part 205 is inserted into the channel 12, the base 204 is exposed outside the opening 11. The magnetic detector 80 is disposed at a position corresponding to the base 204. (Refer to...) Figure 6 , Figure 7 and Figure 12The lock housing 10 can be divided into multiple chambers. The magnetic detector 80 can be located in a different chamber than the latch 20 and the unlocking module 40 to reduce mutual interference. For example, the lock housing 10 has a protrusion on one side of the opening 11, and the magnetic detector 80 can be located in this protrusion. The position of the magnetic detector 80 is higher than the opening 11 relative to the channel 12. When the buckle 203 is inserted into the channel 12, the magnetic element 207 exposed in the base 204 of the opening 11 is directly opposite the magnetic detector 80. In another embodiment, refer to... Figure 15 and Figure 16 The magnetic element 207 is disposed in the insertion part 205 of the buckle 203, and the magnetic detector 80 is disposed on one side of the channel 12. When the insertion part 205 is inserted into the channel 12, the base 204 is exposed outside the opening 11. The magnetic element 207 on the insertion part 205 approaches the magnetic detector 80, so that the magnetic detector 80 detects the magnetic element 207.

[0047] Figure 17 The cross section shown is Figure 15 The cross-sectional positions shown are perpendicular to each other. In one embodiment, referencing Figure 17 At least one locking block 17 is provided on each of the two opposite sides of the channel 12. The buckle 203 has two opposite sides with grooves 208 on surfaces different from the plane of the toothed groove 206. When the buckle 203 is inserted into the channel 12 and properly engaged, the locking block 17 engages with the groove 208, providing the user with tactile feedback to confirm that the buckle 203 is in place. Simultaneously, the engagement of the locking block 17 with the groove 208 also helps prevent the buckle 203 from dislodging. The surfaces of the groove 208 and the locking block 17 are arc-shaped. When the user needs to use the helmet 200, the unlocking module 40 rotates the locking tongue 20 to the unlocked position, applying a certain external force to the buckle 203 to disengage the locking block 17 from the groove 208, thereby pulling out the buckle 203. In one implementation, the locking block 17 can be a protruding structure formed inside the lock housing 10, for example... Figure 17 A latching block 17 on the right side of the central channel 12. In another embodiment, at least one latching block 17 can be elastically connected to the lock housing 10 via a fourth elastic member 18. The latching block 17 is retractable relative to the channel 12 to engage with or disengage from the recess 208. For example, Figure 17 A locking block 17 on the left side of the central channel 12 is elastically connected to the lock housing 10 via a fourth elastic element 18. The fourth elastic element 18 is a spring and is set in the left-right direction as shown in the figure. When the buckle 203 is inserted, the locking block 17 can extend and retract in the left-right direction to slide along the surface of the buckle 203.

[0048] The helmet lock 100 of this utility model embodiment has a lock housing 10 with an opening 11 for inserting a buckle 203 on a helmet 200 and a channel 12 communicating with the opening 11. A locking tongue 20 is provided on one side of the channel 12. The locking tongue 20 includes a locking part 21 and an unlocking part 22. The locking part 21 is rotatably connected to the lock housing 10. The locking part 21 has a locking tooth 211 corresponding to the tooth groove 206 on the surface of the buckle 203. When the locking tongue 20 is in the locked position, the locking part 21 is in the channel 12. When the locking tongue 20 is in the unlocked position, the locking part 21 is out of the channel 12. A first elastic member 30 elastically connects the locking tongue 20 and the lock housing 10 and is configured to keep the locking tongue 20 in the locked position. An unlocking module 40 is used to drive the unlocking part 22 to move the locking tongue 20 from the locked position to the unlocked position to achieve unlocking. Therefore, the helmet lock 100 makes full use of the buckle 203 of the helmet 200 itself to lock the helmet 200, and the locking tongue 20 and the unlocking module 40 realize the self-locking and unlocking of the buckle 203, which is conducive to the simplification of the helmet lock 100 structure and improves the reliability of the helmet lock 100 operation.

[0049] Another aspect of this utility model relates to a vehicle, which may be a bicycle, electric bicycle, motorcycle or other type of straddle-mounted vehicle, which uses the helmet lock assembly described in at least some of the embodiments above. Figure 18 This is a schematic diagram of the vehicle in this embodiment, with reference to... Figure 18 The vehicle includes a body 400, a basket 300, and a helmet lock assembly, wherein the helmet lock assembly is the helmet lock assembly described in at least some of the embodiments above. The basket 300 is fixed to the body 400; for example, the basket 300 assembly may be located at the front of the body 400 and below the handlebars. The basket 300 has a receiving cavity that can open at the top, allowing items to be placed inside, such as a helmet 200 when not worn. (See reference...) Figure 2 , Figure 18 and Figure 19 The helmet lock 100 can be installed inside the receiving cavity. When the helmet 200 is placed in the receiving cavity, the buckle 203 can be easily connected to the helmet lock 100. Furthermore, due to the compact structure of the helmet lock 100, it occupies less space when installed in the receiving cavity, allowing the basket 300 to provide more space for the user's personal belongings while riding the vehicle.

[0050] The basket 300 may have at least one first connecting structure, through which the basket 300 is connected to the vehicle body 400, thus mounting the basket 300 on the vehicle body 400. The specific form, number, and location of the first connecting structure can be selected according to the actual installation needs of the basket 300 and the vehicle body 400. For example, the first connecting structure may be a through hole and there may be multiple holes, through which bolts or other fasteners can be used to fix the basket 300 to the vehicle body 400.

[0051] The basket 300 also has at least one second connecting structure, which is spaced apart from the first connecting structure. The second connecting structure can connect and fix the helmet lock 100 to the basket 300. In one embodiment, the second connecting structure can be a mounting hole, and bolts can be used to connect it to the helmet lock 100 through the mounting hole.

[0052] Reference Figure 3 and Figure 19 The helmet lock 100 has a lock housing 10 with a first cable hole 142, and the side wall of the basket 300 has a second cable hole 301. The second cable hole 301 penetrates the side wall of the basket 300. The cable of the helmet lock 100 passes through the first cable hole 142 and then exits the helmet lock 100. After passing through the second cable hole 301 of the basket 300, it can be connected to other structures on the vehicle. For example, the helmet lock 100 can be electrically connected to the battery in the vehicle via a cable, and the battery can power the device. Another example is that the helmet lock 100 can be electrically connected to a controller located in other positions on the vehicle. In some application scenarios, a cable hole can be provided on the vehicle body 400 at a position corresponding to the basket 300 for the cable to pass through. The cable can be routed through the cable hole into the vehicle body 400. The cable hole can be positioned close to the cable hole to reduce the length of the cable exposed and prevent cable damage.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principle of this utility model should be included within the protection scope of this utility model.
