[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1, please refer to Figures 1-2 A disc brake lock includes a lock disc 2 and a smart lock 3. The smart lock 3 has a locking pin 304. Several locking grooves 203 are formed on the outer surface of the lock disc 2. The locking grooves 203 are for the locking pin 304 to be inserted to achieve locking, and the locking pin 304 is separated from the locking groove 203 to achieve unlocking. The smart lock 3, lock disc 2, and locking grooves 203 are designed to be installed on the brake disc of the vehicle. The lock disc 2 is used to be installed on the rear hook of the vehicle by anti-theft bolts. The locking groove 203 is inserted into the locking pin 304 to lock, and the locking pin 304 is separated from the locking groove 203 to unlock. Compared with traditional automatic brake parking locks, the lock is smaller and lighter. The smart lock 3 has a modular design, a more compact structure, and better waterproof performance.

[0039] Furthermore, such as Figures 1-2 As shown, the smart lock 3 also has a first Hall sensor 306, and a plurality of first magnets 202 are embedded on the outer surface of the lock disc 2. The first magnets 202 and the first Hall sensor 306 work together to detect the rotation speed of the lock disc 2. In order to ensure the safety of users, this application realizes the electronic anti-lock protection function through the cooperation of the first magnets 202 and the first Hall sensor 306. Before each action of the smart lock 3, the first Hall sensor 306 will detect the signal of the first magnets 202 to determine whether the rotation speed of the wheel is within the set safe speed range. If it is within the safe range, the locking action will be performed to ensure the safety of the rider.

[0040] There are two sets of first Hall sensors 306, one set is used and the other is a spare. When the used first Hall sensor 306 fails, the spare first Hall sensor 306 will take over.

[0041] Furthermore, such as Figures 1-2 As shown, the lock disc 2 has several mounting holes 201. The mounting holes 201 are used for mounting the lock disc 2, that is, the lock disc 2 is fixed to the vehicle's brake pads by passing bolts through the mounting holes 201.

[0042] Furthermore, the locking disc 2 is used to install on the vehicle's brake disc, and the smart lock 3 is used to install on the vehicle's rear hook, which is as marked at point A in 1.

[0043] Furthermore, such as Figure 1 and Figure 3As shown, the smart lock 3 is also connected to a fingerprint reader 4, which is used to identify the user. The fingerprint reader 4 is installed on the vehicle frame. The user's identity is identified through the fingerprint reader 4. If the identification is successful, the lock or unlock will be opened.

[0044] Example 2, please refer to Figure 3 A fingerprint lock includes a fingerprint reader 4 and a smart lock 3 electrically connected to the fingerprint reader 4. The smart lock 3 has a locking pin 304. The fingerprint reader 4 is used to identify the user's identity, and the locking pin 304 is activated after the user's identity is successfully identified to lock or unlock. This application uses the fingerprint reader 4 to control the locking and unlocking of the smart lock 3. Compared with traditional automatic parking locks, this application has a smaller size and weight, and the smart lock 3 has a modular design, a more compact structure, and better waterproof performance.

[0045] Furthermore, such as Figure 4 As shown, the smart lock 3 is also connected to the main control board 5. The smart lock 3 is electrically connected to the fingerprint reader 4 through the main control board 5. The main control board 5 plays a role in signal transmission and control coordination, and can accurately transmit the recognition signal of the fingerprint reader 4 to the smart lock 3 to control the action of the lock pin 304.

[0046] Furthermore, such as Figure 5 As shown, the main control board 5 is also connected to the instrument panel 6. The instrument panel 6 can display the status information of the lock (such as whether the lock is open or whether it is faulty), which makes it convenient for users to intuitively understand the working status of the lock, facilitate timely detection and handling of problems, and also improve the overall intelligence level and human-machine interaction of the vehicle.

[0047] Example 3, please refer to Figures 6-9 A lock, the smart lock 3, also includes a protective shell 301, a protective cover 302 and an end cover 303 connected together. The protective shell 301, the protective cover 302 and the end cover 303 are connected by bolts, and a sealing ring is provided at the connection to improve the waterproof effect. A circuit board 305 is installed inside the protective shell 301. A first Hall sensor 306 is set on the circuit board 305. The circuit board 305, the instrument 6 and the fingerprint reader 4 are all connected to the main control board 5.

[0048] Furthermore, such as Figure 6 As shown, a slider 307 is slidably connected inside the protective shell 301. A guide groove 312 is provided at the bottom of the slider 307. A lever 316 is provided in the guide groove 312. One end of the lever 316 extends out of the guide groove 312 and is fixedly connected to a turntable 315. A driving component is connected to the turntable 315. The lever 316 is located at the non-center of the turntable 315, so that when the turntable 315 drives the lever 316 to rotate, the lever 316 can cooperate with the guide groove 312 to drive the slider 307 to move.

[0049] Furthermore, such as Figure 6 and Figure 7 As shown, the driving component includes a motor 313 installed inside the protective housing 301 and connected to the circuit board 305. A support shaft 317 is installed inside the protective housing 301 via bearings. The end of the support shaft 317 is connected to the turntable 315. Both the support shaft 317 and the output shaft of the motor 313 are connected to bevel gears 314. The two bevel gears 314 mesh with each other. When the motor 313 rotates, the turntable 315 can rotate through the bevel gears 314 and the support shaft 317. When the turntable 315 rotates, the slider 307 can be driven to reciprocate through the cooperation of the lever 316 and the guide groove 312.

[0050] Furthermore, such as Figure 7 As shown, the locking pin 304 is inserted and connected to the end cover 303. The outer surface of the locking pin 304 is fitted with a second spring 310 located inside the protective shell 301. When the slider 307 moves away from the locking pin 304, the force of the second spring 310 can drive the locking pin 304 to retract into the protective shell 301.

[0051] Furthermore, such as Figures 6-9 As shown, a T-shaped plate 308 is inserted and connected inside the slider 307. One end of the T-shaped plate 308 extends out of the slider 307 and contacts one end of the locking pin 304. When the slider 307 moves toward the locking pin 304, the locking pin 304 can be pushed out by the force of the first spring 309 and the T-shaped plate 308.

[0052] Furthermore, such as Figure 7 As shown, a groove is provided on the side of the slider 307, and a limiting strip 311 is slidably connected in the groove. The limiting strip 311 is fixedly connected to the inner wall of the protective shell 301. The cooperation between the limiting strip 311 and the groove can limit the movement trajectory of the slider 307 and improve the stability of the slider 307 when it moves.

[0053] Furthermore, a first spring 309 is provided inside the slider 307. One end of the first spring 309 contacts the end of the T-shaped plate 308 away from the locking pin 304. The elastic force of the first spring 309 is greater than the elastic force of the second spring 310.

[0054] Furthermore, such as Figure 8 and Figure 9As shown, a second magnet 318 is provided on the side of the slider 307 near the circuit board 305, and a second Hall sensor 319 and a third Hall sensor 320 are provided on the side of the circuit board 305 near the slider 307. The second magnet 318, the second Hall sensor 319, and the third Hall sensor 320 cooperate to detect the position of the slider 307 to confirm the state of the locking pin 304. When the second magnet 318 moves to the position of the second Hall sensor 319, it is in the unlocked state; when the second magnet 318 moves to the position of the third Hall sensor 320, it is in the locked state. That is, it is determined whether it is in the unlocked or locked state.

[0055] When unlocking, the fingerprint reader 4 recognizes the user's fingerprint. The motor 313 drives the support shaft 317 and turntable 315 to rotate via the bevel gear 314. The turntable 315 then drives the lever 316 to rotate. The lever 316 drives the slider 307 to move away from the locking pin 304 via the guide groove 312. The locking pin 304 retracts under the action of the second spring 310, separating it from the locking groove 203, thus unlocking. When locking, the motor 313 drives the support shaft 317 and turntable 315 to rotate via the bevel gear 314. The turntable 315 then drives the lever 316 to rotate. The lever 316 then... The guide groove 312 drives the slider 307 to move closer to the locking pin 304. The T-shaped plate 308 pushes the locking pin 304 out. If the locking pin 304 is aligned with the locking groove 203, the locking pin 304 can be directly inserted into the locking groove 203. If the locking pin 304 is not aligned with the locking groove 203, the locking pin 304 abuts against the locking disc 2, but the slider 307 moves to the correct position. The first spring 309 and the second spring 310 remain compressed. The vehicle is gently pushed, causing the locking disc 2 to rotate. When the locking pin 304 is aligned with the locking groove 203, the locking pin 304 is inserted into the locking groove 203 under the action of the first spring 309 and the second spring 310.
