The lock cylinder rotates back to its original position under the action of external elastic force, realizing the stop block and the protrusion's stop engagement.

[0004] The aforementioned faucet locks can only be unlocked manually, not electrically, making the unlocking operation rather limited. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a faucet lock that can be unlocked manually or electrically, offering a variety of unlocking methods.

[0006] The technical solution of this utility model is as follows: A faucet lock includes a lock shell, a latch assembly, a lock cylinder, and a rotating shaft. The latch assembly includes a slider and a latch, with the latch connected to the slider. The slider is slidably disposed within the lock shell, and its sliding movement enables the extension and retraction of the latch. The rotating shaft is rotatably disposed on the lock shell, and is circumferentially linked and axially sliding with the lock cylinder. The rotating shaft can drive the slider to slide. A reset element is provided between the rotating shaft and the lock cylinder to drive the lock cylinder to reset outward from the lock shell. A drive mechanism is provided within the lock shell to drive the slider to slide in the unlocking or locking direction. The drive mechanism includes a motor, a drive gear, and a drive block. The drive block is provided with a rack that meshes with the drive gear. The drive block is connected to the slider via a spring to drive the slider to slide when the drive block slides.

[0007] Using the above technical solution, in addition to manual unlocking, electric unlocking can also be performed, offering versatility and a simple drive structure for easy operation. During manual unlocking, the rotating shaft rotates clockwise under the drive of the lock cylinder, driving the slider to slide in the unlocking direction, causing the bolt to retract, while the drive block remains stationary. The rack and drive gear mesh with each other. During electric unlocking, the motor rotates, driving the drive gear to rotate. The drive gear and rack mesh, causing the drive block to slide and driving the slider to slide in the unlocking direction, causing the bolt to retract. The motor rotates in the opposite direction to extend the bolt. Whether unlocking or locking, the drive gear and rack can be separated to prevent the motor from stalling. After the motor stops, the drive block, with the help of spring force, pushes the rack against the drive gear, providing conditions for the rack and drive gear to re-mesh.

[0008] A further feature of this invention is as follows: the slider is provided with a sliding groove that is sleeved on the outside of the drive block, the sliding groove is open on one side, the drive block is provided with a through mounting port, the inner wall opposite to the sliding groove is provided with a receiving groove corresponding to the mounting port, the mounting port is provided with a mounting post, and the two ends of the spring are sleeved on the mounting post and abut against the side wall of the receiving groove.

[0009] With the above-mentioned further configuration, the drive block slides in the drive groove of the motor and cooperates with the side wall of the receiving groove to press against the spring. The spring stores energy to provide thrust for the drive block, which facilitates the positioning and installation of the spring and improves the stability of the spring when compressed, making the spring structure stable. The drive block, through the clutch structure at both ends, can avoid the phenomenon of motor stalling and gear tooth extrusion deformation.

[0010] A further feature of this invention includes a first detection mechanism, comprising a circuit board, a first Hall switch, a second Hall switch, a third Hall switch, a fourth Hall switch, a first magnet, and a second magnet. The motor is connected to the circuit board. The first Hall switch, the second Hall switch, the third Hall switch, and the fourth Hall switch are sequentially arranged on the circuit board along the sliding direction of the drive block. The first magnet is located on the drive block, and the second magnet is located on the slider. The first Hall switch and the second Hall switch cooperate with the first magnet to detect the position of the drive block, and the third Hall switch and the fourth Hall switch cooperate with the second magnet to detect the position of the latch.

[0011] By using the above-mentioned further settings, the positions of the motor and the latch can be precisely locked, ensuring that the motor fully returns to the correct position, avoiding incomplete unlocking, preventing the motor or latch from reactivating if it has not returned to the safe position correctly, and reducing the risk of misoperation or malfunction.

[0012] A further feature of this invention is that the driving mechanism also includes a worm gear and a transmission gear set. The worm gear is located on the output shaft of the motor, and the transmission gear set is located between the worm gear and the driving gear, so as to drive the driving gear to rotate when the motor rotates.

[0013] With the above-mentioned further modifications, the transmission structure is simple, and the transmission is convenient and stable.

[0014] A further feature of this invention is that a drive box is provided inside the lock housing, the motor and circuit board are both located inside the drive box, and the slider and drive block slide outside the drive box.

[0015] The above-mentioned further design improves waterproof performance, preventing rainwater from entering and affecting the operation of the motor and circuit board. The split design of the drive box facilitates the installation of the internal structure, and the ultrasonic welding ensures good sealing.

[0016] A further improvement of this utility model is as follows: the drive box is provided with a bracket, the circuit board is fixedly mounted on the bracket, the circuit board is provided with a Hall circuit board arranged perpendicularly thereto, each Hall switch is mounted on the Hall circuit board, the motor is located below the bracket, and the bracket is provided with a mounting groove adapted to the motor.

[0017] The above-mentioned further design makes the motor and circuit board structure stable and robust. The Hall circuit board is vertically set to facilitate cooperation with the magnet. The circuit board is equipped with external wiring to connect to the power supply on the vehicle to supply power to the circuit board.

[0018] A further feature of this invention is that the lock housing is provided with a second detection mechanism for detecting the rotational position of the pivot. The second detection mechanism includes a micro switch. When the pivot rotates with the lock cylinder to the unlocked position, the pivot can directly or indirectly trigger the contacts of the micro switch to turn on the micro switch.

[0019] With the above-mentioned further configuration, after the key is inserted into the lock cylinder, it drives the lock cylinder to rotate and drives the shaft to rotate. When the shaft rotates to the unlock position, it will trigger the contacts of the micro switch, forming a position signal output, which is fed back to the locomotive controller to determine whether it is in the unlock position.

[0020] A further feature of this invention is that the second detection mechanism also includes a transmission component, which is guided and slidably disposed on the lock housing. An actuating block is provided on the outer circumferential surface of the rotating shaft. When the rotating shaft rotates with the lock cylinder to the unlocking position, the actuating block can press against the transmission component, so that the transmission component presses the contact of the micro switch to conduct the micro switch.

[0021] With the above-mentioned further configuration, the actuating block of the rotating shaft indirectly triggers the contacts of the micro switch through the transmission component, which can avoid damage to the contacts of the micro switch caused by the rotating actuating block directly contacting them, thus extending the service life.

[0022] A further feature of this invention is that a transmission plate is slidably provided inside the lock housing along the extension and retraction direction of the bolt. The transmission plate can drive the slider to slide. The transmission plate has an opening for the rotating shaft to pass through. A contact block is provided on the outer circumference of the rotating shaft at the opening. When the contact block rotates clockwise with the rotating shaft, it can press against the side wall of the opening and drive the transmission plate to move, thereby driving the bolt to retract into the lock housing.

[0023] With the above-mentioned further configuration, the slider has an extension block on the side near the transmission plate. The extension block is inserted into the opening of the transmission plate. Therefore, when the transmission plate moves in the unlocking direction, it can drive the slider to move by contacting the extension block, thereby driving the locking tongue to retract.

[0024] A further feature of this invention is that the lock housing is slidably provided with a pull block connected to an external pull cable, the lock housing is provided with a movable groove for the pull block to slide, the pull block is provided with an abutment part, and a lever is provided on the outer circumference of the rotating shaft. When the lever rotates counterclockwise with the rotating shaft, it can press against the abutment part of the pull block and drive the pull block to slide. A pull spring for driving the pull block to reset is provided in the movable groove.

[0025] With the above-mentioned further configuration, the contact part of the pull cable block is located on the rotation trajectory of the lever block. The rotating shaft rotates counterclockwise, and the lever block presses against the contact part of the pull cable block, causing the pull cable block to move, thereby opening the seat cushion. The pull cable spring drives the pull cable block to automatically reset so that the seat cushion can be opened next time. Attached Figure Description

The latch 22 assembly includes a slider 21 and a latch 22, with the latch 22 connected to the slider 21. The slider 21 is slidably disposed within the lock housing 1, and its sliding movement enables the extension and retraction of the latch 22. The rotating shaft 4 is rotatably disposed on the lock housing 1, and is circumferentially linked and axially slidingly engaged with the lock cylinder 3. The rotating shaft 4 can drive the slider 21 to slide. A reset element 5 is provided between the rotating shaft 4 and the lock cylinder 3 to drive the lock cylinder 3 to return to its original position outside the lock housing 1. The reset element 5 is provided with a reset spring. The lock cylinder 3 has a placement cavity 31 for placing the reset element 5. One end of the reset element 5 abuts against the lock cylinder 3, and the other end abuts against the rotating shaft 4. The structure is simple and the installation is stable.

The lock cylinder 3 and the rotating shaft 4 are connected by the insert 32 and the slot 41 to achieve circumferential rotation and axial sliding, which is convenient for disassembly and assembly. The lock cylinder 3 can drive the rotating shaft 4 to rotate and slide relative to the rotating shaft 4. The lock housing 1 is provided with a driving mechanism for the slider 21 to slide in the unlocking or locking direction. The driving mechanism includes a motor 61, a driving gear 62 and a driving block 63. The driving block 63 is provided with a rack 631 that cooperates with the driving gear 62. The driving block 63 is connected to the slider 21 by a spring 7 so that the slider 21 can slide when the driving block 63 slides. The slider 21 is provided with a sliding groove 211 that fits onto the outside of the driving block 63. One side of the sliding groove 211 is open. The drive block 63 has a through mounting port 632. The inner wall of the sliding groove 211 has a corresponding receiving groove 212. A mounting post 633 is provided within the mounting port 632. The spring 7 is sleeved on the mounting post 633 at both ends and abuts against the side wall of the receiving groove 212.

The drive block 63 remains stationary. The rack 631 meshes with the drive gear 62. During electric unlocking, the motor 61 rotates, driving the drive gear 62 to rotate. The drive gear 62 engages with the rack 631, causing the drive block 63 to slide and drive the slider 21 to slide in the unlocking direction, causing the bolt 22 to retract. Reversing the rotation of the motor 61 extends the bolt 22. Whether unlocking or locking, the drive gear 62 and rack 631 can be separated to prevent the motor 61 from stalling. After the motor 61 stops, the drive block 63, pushed by the spring 7, causes the rack 631 to press against the drive gear 62, providing conditions for the rack 631 and drive gear 62 to re-mesh.The drive block 63, through its two-end clutch structure, can prevent the motor 61 from stalling and avoid gear tooth deformation due to compression.

[0033] It also includes a first detection mechanism, which comprises a circuit board 81, a first Hall switch 82, a second Hall switch 83, a third Hall switch 84, a fourth Hall switch 85, a first magnet 86, and a second magnet 87.

The first Hall switch 82, the second Hall switch 83, the third Hall switch 84, and the fourth Hall switch 85 are sequentially arranged on the circuit board 81 along the sliding direction of the drive block 63. The first magnet 86 is located on the drive block 63, and the second magnet 87 is located on the slider 21. The first Hall switch 82 and the second Hall switch 83 cooperate with the first magnet 86 to detect the position of the drive block 63. The third Hall switch 84 and the fourth Hall switch cooperate with the second magnet 87 to detect the position of the latch 22. This can accurately lock the position of the motor 61 and the latch 22, ensuring that the motor 61 fully returns to the correct position, avoiding incomplete unlocking, and preventing the motor 61 or the latch 22 from reactivating if it has not returned to the safe position correctly, thus reducing the risk of misoperation or malfunction.

[0034] The drive mechanism also includes a worm gear 64 and a transmission gear set 65.

[0036] The lock housing 1 is provided with a second detection mechanism for detecting the rotational position of the rotating shaft 4. The second detection mechanism includes a micro switch 101. When the rotating shaft 4 rotates with the lock cylinder 3 to the unlocked position, the rotating shaft 4 can directly or indirectly trigger the contact of the micro switch 101 to conduct the micro switch 101. After the key is inserted into the lock cylinder 3, it drives the lock cylinder 3 to rotate and drives the rotating shaft 4 to rotate. When the rotating shaft 4 rotates to the unlocked position, it will trigger the contact of the micro switch 101 to form a position signal output, which is fed back to the locomotive controller to determine whether it is in the unlocked position. The second detection mechanism also includes a transmission component 102, which is guided and slidably disposed on the lock housing 1. An actuating block 42 is provided on the outer peripheral surface of the rotating shaft 4.

The actuating block 42 of the rotating shaft 4 indirectly triggers the contact of the micro switch 101 through the transmission component 102, which can avoid damage to the contact of the micro switch 101 caused by the rotating actuating block 42 directly contacting the contact of the micro switch 101, thus extending the service life. The end of the transmission component 102 near the rotating shaft 4 is spherical. The lock housing 1 is provided with a sliding cavity for the transmission component 102 to be placed. The spherical surface of the transmission component 102 extends out of the port of the sliding cavity, and the other end of the transmission component 102 abuts against the contact of the micro switch 101.

The transmission plate 11 has an opening 111 through which the rotating shaft 4 passes. A contact block 43 is provided on the outer circumference of the rotating shaft 4 corresponding to the opening 111. When the contact block 43 rotates clockwise with the rotating shaft 4, it can press against the side wall of the opening 111 and drive the transmission plate 11 to move, thereby driving the bolt 22 to retract into the lock housing 1. The slider 21 has an extension block on the side near the transmission plate 11. The extension block is inserted into the opening 111 of the transmission plate 11. Therefore, when the transmission plate 11 moves in the unlocking direction, it can drive the slider 21 to move by contacting the extension block, thereby driving the bolt 22 to retract.
