Abstract
Description
Technical Field
[0001] This invention relates to a double-locking structure, and more particularly to a double-locking structure that can lock both a helmet and a vehicle. Background Technology
[0002] Whether riding an electric scooter normally or cycling on mountain roads, a safety helmet is necessary. There are many locks on the market for preventing theft of vehicles, such as steel cable locks. If you need to lock the helmet as well, you need to add a separate lock body to lock the helmet separately. For example, the patent with publication number CN215671640U, entitled "A Pin Helmet Lock Structure", only provides the anti-theft function for the helmet. How to create a double-headed lock that can lock two helmets or lock both the vehicle and the helmet is the technical problem we need to solve now. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this invention provides a double-locking structure.
[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a double-lock structure, characterized in that it includes a housing for mounting a motor, a reciprocating slider inside the housing, a first locking block on one side of the slider for unlocking a first external locking device and engaging with the slider, a second locking block on the other side of the slider for unlocking a second external locking device, and a button on the housing for unlocking the second external locking device by pushing the second locking block. The movement of the button is restricted by the slider. When the slider moves in the unlocking direction via the motor, the first external locking device is unlocked through the cooperation of the slider and the first locking block. The button is released from restriction through the cooperation of the slider and the second external locking device is unlocked through the reciprocating movement of the button.
[0005] The slider is provided with a stop part to prevent the button from being pressed down, and the bottom of the button is provided with a stop part that cooperates with the stop part. The button is limited by the cooperation of the stop part and the stop part.
[0006] The housing is provided with a guide groove that matches the slider. The motor includes an output shaft, and the output shaft is provided with a guide block that is linked to the output shaft and is used to force the slider to move in the unlocking direction. The slider is provided with a protrusion that matches the guide block. The slider moves in the unlocking direction through the cooperation of the guide block and the protrusion.
[0007] The first locking block is provided with a locking groove for cooperating with the first external locking device. The first external locking device is locked to the housing through the locking groove. The first locking block is provided with a first elastic device that forces the first locking block to move in the locking direction.
[0008] The second locking block is provided with a locking tongue for cooperating with the second external locking device. The second external locking device is locked to the housing by the locking tongue. The second locking block is provided with a second elastic device that forces the second locking block to move in the locking direction.
[0009] The housing is provided with a groove to limit the reciprocating motion of the slider, and the slider is provided with a locking block that cooperates with the groove. The slider achieves limited reciprocating motion on the housing through the cooperation of the groove and the locking block.
[0010] The bottom of the button is provided with an inclined surface that forces the second locking block to reciprocate. The second locking block is provided with a guide surface that matches the inclined surface. The second locking block achieves reciprocating motion through the inclined surface and the guide surface and through the action of the button.
[0011] The button is equipped with a third elastic device to prevent the button from unlocking the second lock block.
[0012] A first electronic switch is provided inside the housing and at the bottom position relative to the first external locking device, which abuts against the first external locking device. A second electronic switch is provided inside the housing and at the bottom position relative to the second external locking device, which abuts against the second external locking device. The first electronic switch, the second electronic switch and the motor are electrically connected. When the first external locking device and the second external locking device are disengaged from the first electronic switch and the second electronic switch respectively, the motor releases the slider by receiving signals from the first electronic switch and the second electronic switch.
[0013] The housing contains a lock cylinder that rotates with the housing. The lock cylinder has a rotating block that is linked with the lock cylinder. The slider has a protrusion that engages with the rotating block. When the lock cylinder is unlocked, the rotating block rotates with the lock cylinder and unlocks the slider by engaging with the protrusion.
[0014] The beneficial effects of this invention are as follows: By integrating two locking mechanisms within a single housing, this invention can be used to lock items such as helmets and vehicles. One mechanism is automatically unlocked by a motor, while the other is operated via a mechanical button. Both mechanisms share a continuous, linked slider, a first locking block, and a second locking block. This design effectively controls manufacturing costs while ensuring the overall structure's stability and reliability. Furthermore, this invention has the advantages of simple construction, convenient processing, and suitable assembly, making it highly practical and suitable for widespread use.

Detailed Implementation
[0026] like Figures 1-10As shown, a double-lock structure includes a housing 100 for mounting a motor 110. Inside the housing 100 is a reciprocating slider 200. One side of the slider 200 has a first locking block 210 for unlocking a first external locking device 211 and engaging with the slider 200. The other side of the slider 200 has a second locking block 220 for unlocking a second external locking device 221. The housing 100 has a button 230 for unlocking the second external locking device 221 by pushing the second locking block 220. The movement of the button 230 is restricted by the slider 200. When the slider 200 moves in the unlocking direction via the motor 110, the first external locking device 211 is unlocked through the interaction of the slider 200 and the first locking block 210. The button 230 is released through the interaction of the slider 200 and through the reciprocating motion of the button 230. The movement unlocks the second external locking device 221. The first external locking device 211 and the second external locking device 221 are not limited to locking helmets, electric bicycles, or electric bikes. The attached diagram of the instruction manual shows the first external locking device 211 as a steel cable lock and the second external locking device 221 as a buckle on a helmet. The motor 110 is controlled by the electric control system on the electric bicycle. As long as the electric bicycle is unlocked, the motor 110 can release the first locking block 210, and the electric bicycle can be taken away. The communication between the electric bicycle and the motor 110 can be carried out through Bluetooth connection or cloud, etc., which are mature technologies on the market and will not be described in detail here. Please refer to the application with publication number CN120108072A, entitled "Vehicle remote control method, system and device based on remote locking platform". The usage method is detailed below.
[0027] The slider 200 is provided with a stop part 240 to prevent the button 230 from being pressed down. The bottom of the button 230 is provided with a stop part 231 that cooperates with the stop part 240. The button 230 is limited by the cooperation of the stop part 231 and the stop part 240. The stop part 240 moves with the slider 200. When the stop part 240 moves to the stop part 231, the button 230 cannot be pressed down, and the second locking block 220 cannot be unlocked. When the stop part 240 leaves the stop part 231, the button 230 can be pressed down, and the second locking block 220 can be unlocked.
[0028] The housing 100 is provided with a guide groove 120 that cooperates with the slider 200. The motor 110 includes an output shaft 111. The output shaft 111 is provided with a guide block 112 that is linked to the output shaft 111 and is used to force the slider 200 to move in the unlocking direction. The slider 200 is provided with a protrusion 250 that cooperates with the guide block 112. The slider 200 moves in the unlocking direction through the cooperation of the guide block 112 and the protrusion 250.
[0029] The first locking block 210 is provided with a locking groove 212 for cooperating with the first external locking device 211. The first external locking device 211 is locked to the housing 100 through the locking groove 212. The first locking block 210 is provided with a first elastic device 213 that forces the first locking block 210 to move in the locking direction. The locking groove 212 is mainly adapted to steel cable locks, but this application is not limited to the use of steel cable locks. The first elastic device 213 preferably adopts a spring structure, which is convenient to install and has low cost.
[0030] The second locking block 220 is provided with a locking tongue 222 for cooperating with the second external locking device 221. The second external locking device 221 is locked to the housing 100 by the locking tongue 222. The second locking block 220 is provided with a second elastic device 223 that forces the second locking block 220 to move in the locking direction. The locking tongue 222 is mainly adapted to the helmet buckle, but this application is not limited to the use of buckles. The second elastic device 223 is preferably a spring structure, which is easy to install and has low cost.
[0031] The housing 100 is provided with a groove 130 to limit the reciprocating motion of the slider 200. The slider 200 is provided with a locking block 260 that cooperates with the groove 130. The slider 200 achieves limited reciprocating motion on the housing 100 through the cooperation of the groove 130 and the locking block 260. The cooperation of the groove 130 and the locking block 260 achieves limited sliding of the slider 200 within the housing 100.
[0032] The bottom of the button 230 is provided with an inclined surface 232 that forces the second locking block 220 to reciprocate. The second locking block 220 is provided with a guide surface 224 that cooperates with the inclined surface 232. The second locking block 220 achieves reciprocating motion through the cooperation of the inclined surface 232 and the guide surface 224 and the button 230. The inclined surface 232 has an inclination, which pushes the second locking block 220.
[0033] The button 230 is provided with a third elastic device 233 to prevent the button 230 from unlocking the second locking block 220. The third elastic device 233 is preferably a spring structure, which is easy to install and has low cost.
[0034] A first electronic switch 300, which abuts against the first external locking device 211, is located inside the housing 100 and at the bottom position relative to the first external locking device 211. A second electronic switch 400, which abuts against the second external locking device 221, is located inside the housing 100 and at the bottom position relative to the second external locking device 221. The first electronic switch 300, the second electronic switch 400, and the motor 110 are electrically connected. When the first external locking device 211 and the second external locking device 221 disengage from the first electronic switch 300 and the second electronic switch 400, respectively, the motor 110 releases the unlocking of the slider 200 by receiving signals from the first electronic switch 300 and the second electronic switch 400. The first electronic switch 300 and the second electronic switch 400 can be microswitches. The spring on the microswitch has two signals: pressing and releasing. The addition of the first electronic switch 300 and the second electronic switch 400 mainly adds a function that requires the helmet to be removed before locking after taking off the vehicle. This function can be controlled by communication devices such as mobile phones. Adding this function mainly reminds or forces users to wear helmets, improves driving safety, and is highly practical.
[0035] The housing 100 contains a lock cylinder 500 that rotates with the housing 100. The lock cylinder 500 has a rotating block 510 that is linked with the lock cylinder 500. The slider 200 has a protrusion 270 that engages with the rotating block 510. When the lock cylinder 500 is unlocked, the rotating block 510 rotates with the lock cylinder 500 and unlocks the slider 200 by engaging with the protrusion 270. If the lock cylinder 500 is used as a backup unlocking method, inserting the correct key and rotating the lock cylinder 500 will cause the slider 200 to move by engaging with the rotating block 510 and the protrusion 270, which can also unlock the first lock block 210. The button 230 can also be pressed to unlock the second lock block 220.
[0036] How to use:
[0037] In the initial state, the slider 200 is in the locked position. At this time, the first locking block 210 locks the first external locking device 211, while the slider 200 presses against the button 230, and the button 230 cannot be pressed down at this time. The second locking block 220 locks the second external locking device 221, and the lock body enters the locked state.
[0038] When the vehicle is needed, first unlock the electric scooter or bicycle. The vehicle's electronic control system transmits power to the motor 110 of the lock body. The rotation of the motor 110, through the cooperation of the guide block 112 and the protrusion 250, causes the slider 200 to move in the unlocking direction. Since the slider 200 is linked to the first locking block 210, the first locking block 210 also moves in the unlocking direction, thus unlocking the first external locking device 211. The vehicle can then be taken out and ridden. Because the anti-reverse part 240 on the slider 200 has moved away from the stop part 231 of the button 230, the button 230 can be pressed to... The second locking block 220 unlocks the second external locking device 221. Since the first external locking device 211 and the second external locking device 221 have been removed, the first electronic switch 300 and the second electronic switch 400 receive signals, the motor 110 rotates and resets, and the slider 200, the first locking block 210 and the second locking block 220 also begin to reset with the cooperation of the first elastic device 213 and the second elastic device 223. The lock body is in an empty locking state, waiting for the first external locking device 211 and the second external locking device 221 to be inserted into the lock body to lock.
