[0002] A brake lock is a lock installed on a vehicle braking system to achieve the purpose of anti-theft and preventing accidental movement of the vehicle. According to different installation positions and principles, brake locks can be divided into various types, but the most common ones are disc brake locks designed for motorcycles with disc brakes and brake pedal locks installed on the brake pedals of automobiles. In special cases, brake locks can serve as an additional safeguard to prevent accidental sliding of the vehicle, which plays a significant role in protecting vehicle safety.

[0003] In the prior art, the lock core of a brake lock commonly uses a gear to drive a rack, and then the rack pushes a lock pin to reciprocate to lock the brake disc. During the sliding process of the rack, the contact area with the guide sleeve is relatively large. After long-term use, the rack may be severely worn, which not only reduces the service life of the brake lock, but also the frictional resistance of the rack is relatively large, affecting the transmission effect of the gear, and further reducing the use safety of the brake lock.

[0004] Therefore, it is urgent to improve the driving mechanism of the brake lock core to solve the above problems. Summary of the Utility Model

[0027] The following will detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0028] As Figures 1 - 6 shown, the brake lock cylinder driving mechanism provided in this embodiment includes a housing assembly 1 and a brake disc assembly 2 fixedly installed inside the housing assembly 1. A lock cylinder assembly 3 is fixedly arranged inside the housing assembly 1. The lock cylinder assembly 3 is arranged on one side of the brake disc assembly 2. A waterproof wire 4 is fixedly installed inside the lock cylinder assembly 3, and the waterproof wire 4 extends to the outside of the housing assembly 1. The waterproof wire 4 is used to receive a locking signal. The lock cylinder assembly 3 includes a motor base 31 and a motor 32 fixedly installed inside the motor base 31. The output end of the motor 32 is fixedly connected to a worm 33. A gear set 34 is meshed and connected to one side of the worm 33. A sector gear 35 is meshed and connected to one end of the gear set 34. A rocker arm 36 is fixedly connected to the end of the sector gear 35 away from the gear set 34. The end of the rocker arm 36 away from the sector gear 35 is rotatably connected to a lock cylinder 37, and the lock cylinder 37 corresponds to the brake disc assembly 2;

[0029] The motor 32 is used to provide driving force to drive the gear set 34 to work. A motor gland 38 is fixedly arranged on the upper side of the lock cylinder assembly 3. The gear set 34 is rotatably arranged on the motor gland 38. The motor gland 38 can fix the motor 32 and the gear set 34. A chute 381 is opened on the motor gland 38. A slider 351 is fixedly arranged on the side of the sector gear 35 corresponding to the motor gland 38. The slider 351 is slidably arranged inside the chute 381. During the rotation of the sector gear 35, the slider 351 slides inside the chute 381. On the one hand, it can provide a guiding effect for the sector gear 35, and on the other hand, the chute 381 can limit the sector gear 35 through the slider 351;

[0030] Among them, the motor 32 drives the gear set 34 to work through the worm 33. The gear set 34 drives the sector gear 35 to rotate. The sector gear 35 drives the rocker arm 36 to swing, and then the rocker arm 36 swings to drive the lock cylinder 37 to reciprocate, so as to realize the locking of the brake disc, avoiding the traditional locking method of rack drive. The resistance and wear of the circular motion of the sector gear 35 are much smaller than those of the linear motion rack. It not only increases the driving force of the lock cylinder 37, but also has less wear, thus greatly extending the service life of the brake lock.

[0031] Further, as Figure 5 and Figure 6 shown, a number of uniformly distributed lock ports 21 are opened on the brake disc assembly 2. The lock cylinder 37 includes a mounting shell 371 and a U-shaped connecting groove 372 fixedly installed on the mounting shell 371. The lock cylinder 37 is rotatably connected to the rocker arm 36 through the U-shaped connecting groove 372. A spring 373 is slidably arranged inside the mounting shell 371. One end of the spring 373 is fixedly connected to a lock pin 374. The lock pin 374 extends to the outside of the mounting shell 371. The end of the lock pin 374 away from the mounting shell 371 corresponds to the lock port 21;

[0032] One end of the rocker arm 36 can rotate within the U-shaped connection groove 372, converting the circumferential driving force of the sector gear 35 into a linear driving force. During the process of the sector gear 35 driving the lock core 37 to slide through the rocker arm 36, the lock pin 374 first abuts against the outside of the brake disc assembly 2. When the lock port 21 on the brake disc assembly 2 rotates to the position of the lock pin 374, the lock pin 374 is inserted into the lock port 21 under the elastic force of the spring 373 to lock the brake disc assembly 2. The spring 373 can protect the lock core 37 to prevent the driving force of the sector gear 35 from being too large and deforming the lock pin 374.

[0033] Furthermore, as Figure 2 shown, a Hall element 5 is fixedly arranged inside the lock core assembly 3, and a plurality of evenly distributed magnets 22 are fixedly installed on the outside of the brake disc assembly 2. The magnets 22 correspond to the Hall element 5. When a locking signal is received from the waterproof wire 4, first, the rotation speed of the wheel is determined by the magnets 22 and the Hall element 5. If it is higher than the safe speed, the locking action is not performed. If it is lower than the safe speed, the locking action is executed, and a locking success signal is fed back, thus greatly improving the safety of the brake lock.

[0034] Still further, as Figure 5 shown, the motor 32 is fixedly installed on the motor gland 38. The gear set 34 includes a first gear 341 and a second gear 342. The first gear 341 meshes with the worm 33, one side of the second gear 342 meshes with the first gear 341, and the other side of the second gear 342 meshes with the sector gear 35. Both the first gear 341 and the second gear 342 are rotatably arranged on the motor gland 38 through shaft rods. The motor gland 38 can fix the motor 32, the first gear 341, the second gear 342, and the sector gear 35, making the rotation of the gear set 34 and the sector gear 35 more stable, thereby improving the locking effect of the brake lock. The motor 32 drives the first gear 341 to rotate through the worm 33, the first gear 341 drives the second gear 342 to rotate, and the second gear 342 drives the sector gear 35 to rotate. The multi-stage transmission can adjust the driving force of the sector gear 35;

[0035] At the same time, as Figure 2 shown, a circuit board 39 is fixedly installed on the upper side of the motor base 31, and a lock core base 310 is fixedly installed on the upper sides of the motor base 31 and the circuit board 39. The lock core assembly 3 is fixedly installed inside the housing assembly 1 through the lock core base 310. A plurality of evenly distributed blind rivets 6 are fixedly installed on the lock core base 310. The blind rivets 6 penetrate through the lock core assembly 3 and the housing assembly 1 and extend to the other side of the housing assembly 1; the circuit board 39 is electrically connected to the waterproof wire 4 through a wire for facilitating the control of the motor 32. The blind rivets 6 facilitate the installation of the lock core assembly 3 and the housing assembly into a whole, facilitating the installation of the brake lock.

[0036] In addition, as Figure 2 andFigure 3 As shown, a sealing ring 7 is fixedly arranged on the waterproof wire 4. The sealing ring 7 is fixedly arranged outside the motor base 31. The sealing ring 7 can prevent dust and water from entering the motor base 31, and can prevent the motor 32 from being short-circuited and burned out.

[0037] As Figures 1 - 6 shown, the principle of the brake lock core driving mechanism provided in this embodiment is as follows:

[0038] After the waterproof wire 4 receives the signal of locking the lock, it first determines the wheel speed through the magnet 22 and the Hall element 5. If the speed is higher than the safe speed, the locking action is not performed. If the speed is lower than the safe speed, the locking action is executed to start the motor 32. The motor 32 drives the first gear 341 to rotate through the worm 33. The first gear 341 drives the second gear 342 to rotate. The second gear 342 drives the sector gear 35 to rotate. The sector gear 35 is used to drive the swing arm 36 to swing. Then, the swing of the swing arm 36 drives the lock core 37 to slide. The lock pin 374 first abuts against the outside of the brake disc assembly 2. When the lock port 21 on the brake disc assembly 2 rotates to the position of the lock pin 374, the lock pin 374 is inserted into the lock port 21 under the elastic force of the spring 373 to lock the brake disc assembly 2.
