DETAILED DESCRIPTION

[0026] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0027] like Figure 1-Figure 5 As shown, the new brake assembly provided by this embodiment includes a housing assembly 1, a motor base 2 is fixedly installed inside the housing assembly 1, a first motor 3 is fixedly installed on the motor base 2, a first bevel gear 4 is fixedly installed inside the first motor 3, a second bevel gear 5 is fixedly installed on the output end of the first bevel gear 4, a cam 6 is meshed and connected on the second bevel gear 5, a push column 7 is fixedly installed on the cam 6, a slider 8 is slidably provided on the motor base 2 at the position corresponding to the push column 7, a notch 9 is provided on the slider 8, and the slider 8 is slidably provided inside the notch 9, the first motor 3 drives the second bevel gear 5 to rotate through the first bevel gear 4, and then the cam 6 drives the slider 8 to swing through the push column 7, and then slides through the slider 8, thereby realizing the locking work of the brake lock;

[0028] A gate disc assembly 10 is fixedly installed inside the housing assembly 1. The slider 8 corresponds to the gate disc assembly 10. Several evenly distributed magnets A11 are fixedly installed on the gate disc assembly 10. A Hall A21 is fixedly installed at the position of the motor base 2 corresponding to the gate disc assembly 10. Halls B22 are fixedly installed on both sides of the cam 6 of the motor base 2. A magnet B12 is fixedly installed inside the cam 6 or the slider 8. The Hall B22 corresponds to the magnet B12. When the locking signal is received from the waterproof line 18, the wheel speed is first determined by the magnet A11 and the Hall A21.

[0029] Among them, the first motor 3 drives the second bevel gear 5 to rotate through the first bevel gear 4, which in turn causes the cam 6 to swing the slider 8 through the push column 7, and then the slider 8 slides, thereby realizing the locking of the brake lock, effectively reducing the wear of the lock cylinder. The magnet B12 on the cam 6 and the Hall effect B22 on the motor base 2 are used to determine the rotation stroke, avoiding the design of traditionally used paddle switches, travel switches, contact switches, etc. to determine the stroke, thereby improving the locking accuracy of the lock cylinder;

[0030] Specifically, the unlocking signal is received through the waterproof line 18, and the wheel speed is first determined by the magnet A11 and the Hall A21. 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 performed, the first motor 3 is started to unlock, and the locking success signal is fed back. Each time the first motor 3 rotates, the second bevel gear 5 rotates, and the magnet B12 on the cam 6 reaches the left and right positions of the Hall B22 as a stroke judgment, thereby pushing the lock pin 16 to reciprocate; the unlocking and locking functions are realized. If it fails, the unlocking failure signal is fed back.

[0031] Further, such as Figure 4As shown, the brake disc assembly 10 includes a brake disc 101 and a brake rocker arm 102 rotatably arranged inside the brake disc 101. The brake rocker arm 102 extends to the outside of the housing assembly 1. An eccentric wheel 103 is fixedly installed at one end of the brake rocker arm 102. The end of the brake rocker arm 102 away from the brake disc 101 is fixedly connected to the brake line. Two symmetrically distributed brake shoes 104 are rotatably arranged inside the brake disc assembly 10. One end of the brake shoe 104 is rotatably arranged on the shaft of the brake rocker arm 102. The side of the eccentric wheel 103 is against the side of the brake rocker arm 102. Two symmetrically distributed tension springs 105 are hung between the two brake shoes 104. The tension springs 105 are used to reset the two brake shoes 104.

[0032] At the same time, if Figure 3 and Figure 4 As shown, a follower brake 106 is fixedly provided at one end of the brake shoe 104 away from the brake rocker arm 102. The follower brake 106 extends to the outside of the housing assembly 1. A plurality of evenly distributed lock grooves 107 are opened on the brake disc 101. A spring 15 is fixedly connected to the inner side wall of the slider 8. A lock pin 16 is fixedly installed at one end of the spring 15. The lock pin 16 extends to the outside of the slider 8 and corresponds to the lock groove 107. The spring 15 is used to protect the lock pin 16. The follower brake 106 can improve braking safety and can also act on the drum brake structure.

[0033] Among them, when braking, the brake line drives the brake rocker arm 102 to swing, thereby driving the eccentric wheel 103 to rotate. The rotating side of the eccentric wheel 103 contacts the brake shoe 104, and then pushes the two brake shoes 104 to open and rub against the brake disc 101 to achieve the purpose of braking. The tension spring 105 is used to reset the two brake shoes 104, and the spring 15 can prevent the lock pin 16 from deforming. After braking, the first motor 3 drives the slider 8 to slide the transmission lock pin 16 to engage with the lock slot 107, which greatly improves the safety of locking the car.

[0034] like Figure 1 and Figure 5 As shown, the new brake lock provided in this embodiment includes a housing assembly 1 and a motor base 2, a second motor 13 is fixedly mounted on the motor base 2, a cam 6 is fixedly mounted on the output end of the second motor 13, a push column 7 is fixedly mounted on the side of the cam 6 away from the second motor 13, a lock core seat 17 is fixedly mounted on the motor base 2 by bolts, the first motor 3 and the second motor 13 are both fixedly mounted inside the lock core seat 17, a waterproof line 18 is fixedly connected to the inside of the lock core seat 17, and the waterproof line 18 extends to the outside of the housing assembly 1, a slide groove 23 is opened on the side of the motor base 2 away from the first motor 3, and the slider 8 is slidably set on the motor base 2 through the slide groove 23;

[0035] Among them, the cam 6 is directly driven to rotate by the second motor 13, the structure is simpler, and the transmission efficiency of the locking pin 16 can be improved. The transmission of the second electrode 13 and the transmission of the first motor 3 through the first bevel gear 4 can both reduce the wear of the workpiece, and are connected to the slot 9 through the push column 7, with low noise and long distance, thereby improving the stability and accuracy of the transmission of the locking pin 16.

[0036] like Figure 1-Figure 5 As shown, the principles of the new brake assembly and brake lock provided in this embodiment are as follows:

[0037] The unlocking signal is received through the waterproof line 18, and the wheel speed is first determined by the magnet A11 and the Hall A21. 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 performed, and the first motor 3 is started to unlock. The first motor 3 drives the second bevel gear 5 to rotate through the first bevel gear 4, and then the cam 6 drives the slider 8 to swing through the push column 7, and then slides through the slider 8, thereby realizing the locking of the brake lock, effectively reducing the wear of the lock cylinder. When braking, the brake rocker arm 102 is driven to swing through the brake line, thereby driving the eccentric wheel 103 to rotate, and the rotating side of the eccentric wheel 103 contacts the brake shoe 104, thereby pushing the two brake shoes 104 to open and rub against the brake disc 101 to achieve the purpose of braking. The magnet B12 on the cam 6 or the slider 8 and the Hall B22 on the motor base 2 are used to determine the rotation stroke, avoiding the traditional design of determining the stroke by using paddle switches, travel switches, contact switches, etc.
