Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a brake motor with a locking function. Background Art

[0002] The automotive brake motor is an important automotive component that achieves braking function through electromagnetic effects and mechanical friction. However, although traditional brake motors can respond to control commands to stop rotating after the vehicle stops, it is often difficult to completely avoid slight slippage of the motor shaft due to vibration or external interference. This slippage not only affects the accuracy of the braking effect, but also poses a potential risk to the vehicle's parking stability and passenger safety. Therefore, we propose a brake motor with a locking function to solve the above problems. Utility Model Content

The rotor 10 is installed on the outside of the rod body between the stators 6, and the rotor 10 is movably located inside the stator 6. The locking mechanism 4 includes a fixed block 401, which is fixedly installed at the lower end of the motor housing 1. A gear 402 is movably installed in the middle of the locking groove 102.

A movable block 403 is movably installed at the lower end of the inside of the locking groove 102. A plurality of teeth 404 are installed on the upper end of the movable block 403, and the teeth 404 are meshed with the gear 402.

[0022] like Figures 3 to 5As shown, in another embodiment of the present invention, a movable groove 103 is provided on the rear side of the motor housing 1, and the rear end of the shaft 2 is movably installed in the movable groove 103. The fan blade 9 is movably installed in the movable groove 103, and the shaft 2 is connected to the fan blade 9. A plurality of air inlet holes 8 are provided at both ends of the interior of the locking groove 102. The air inlet holes 8 are respectively connected to the temporary storage groove 101 and the movable groove 103. A plurality of air outlet holes 7 are provided inside the temporary storage groove 101 and at one end close to the bearing 3. Filters are installed inside the air inlet hole 8 and the air outlet hole 7, respectively. The outside of the motor housing 1 is installed There are several heat sinks 5, and a groove 407 is provided inside the fixed block 401. A plurality of guide rods 405 are movably installed on the upper end of the inner part of the groove 407. The upper end of the rod body of the guide rod 405 is connected to the movable block 403. The outer side of the rod body of the guide rod 405 located between the movable block 403 and the locking groove 102 is respectively sleeved with a spring 406.

[0023] When the rotor 10 cooperates with the stator 6 to control the rotation of the shaft 2, the shaft 2 will drive the gear 402 and the fan blades 9 to rotate, and then the fan blades 9 enter the interior of the temporary storage tank 101 through the air inlet 8 to take away the heat generated by the rotor 10 when rotating at high speed, and let the heat be discharged along the air outlet 7 along the air flow, so as to cooperate with the heat sink 5 to improve the overall heat dissipation efficiency. Then, when the user needs to control the shaft 2 to brake and stop, as the speed of the shaft 2 gradually decreases, and then after the shaft 2 stops rotating, the user can cut off the power to the electromagnet 408, so that the magnetic field generated by the power supply in the electromagnet 408 disappears, and then after the electromagnet 408 is cut off, the spring 406 can push the guide rod 405 to move upward, so that the guide rod 405 is separated from the electromagnet 408, and at the same time promotes the activity. The block 403 moves upward, so that the movable block 403 drives the teeth 404 to mesh with the gear 402, thereby realizing the locking of the gear 402 and the rotating shaft 2, avoiding the slight sliding of the rotating shaft 2 caused by inertia, vibration or external interference, and improving the stability of the rotating shaft 2. Then, when it is necessary to control the rotation of the rotating shaft 2, the user supplies power to the electromagnet 408, so that the electromagnet 408 generates a magnetic field due to the power supply, and then the magnetic block 409 can be attracted to move downward, so that the magnetic block 409 drives the guide rod 405 to move, and the guide rod 405 drives the movable block 403 and the teeth 404 to move downward, so that the teeth 404 and the gear 402 are separated, and at the same time, the movable block 403 squeezes the spring 406, waiting for the next locking of the gear 402 and the rotating shaft 2;

[0024] The filter is used to filter dust and impurities in the air to prevent the impurities from entering the temporary storage tank 101 along with the air and causing erosion and wear on the rotor 10 and the stator 6, thereby extending the overall service life.

[0025] The working principle of a brake motor with locking function:

[0026] During use, first, when the rotor 10 cooperates with the stator 6 to control the rotation shaft 2 to rotate, the rotation shaft 2 will drive the gear 402 and the fan blade 9 to rotate, and then the fan blade 9 enters the interior of the temporary storage tank 101 through the air inlet 8 to take away the heat generated by the rotor 10 when rotating at high speed, and let the heat be discharged along the air outlet 7 along the air flow, so as to cooperate with the heat sink 5 to improve the overall heat dissipation efficiency, and then when the user needs to control the rotation shaft 2 to brake and stop, as the speed of the rotation shaft 2 gradually decreases, and then after the rotation shaft 2 stops rotating, the user can cut off the power to the electromagnet 408, so that the magnetic field generated by the power supply in the electromagnet 408 disappears, and then after the electromagnet 408 is cut off, the spring 406 can push the guide rod 405 to move upward, so that the guide rod 405 is separated from the electromagnet 408, and at the same time push The movable block 403 moves upward, so that the movable block 403 drives the teeth 404 to mesh with the gear 402, thereby realizing the locking of the gear 402 and the rotating shaft 2, avoiding the slight sliding of the rotating shaft 2 caused by inertia, vibration or external interference, and improving the stability of the rotating shaft 2. Then, when it is necessary to control the rotation of the rotating shaft 2, the user powers the electromagnet 408, so that the electromagnet 408 generates a magnetic field due to the power supply, and then the magnetic block 409 can be attracted to move downward, so that the magnetic block 409 drives the guide rod 405 to move, and the guide rod 405 drives the movable block 403 and the teeth 404 to move downward, so that the teeth 404 and the gear 402 are separated, and at the same time, the movable block 403 squeezes the spring 406, waiting for the next locking of the gear 402 and the rotating shaft 2.
