Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Such as Figures 1 to 4As shown in the figure, the utility model provides a bicycle braking speed sensor simulation auxiliary tooling, which includes a tooling housing 1. A speed measurement gear 4 is rotatably arranged on the outer side of the tooling housing 1. A gear protective cover 5 is sleeved on the outer side of the speed measurement gear 4, and the outer side of the gear protective cover 5 is detachably connected to the outer side of the tooling housing 1. A fixed bracket 6 is fixedly arranged on the outer side of the tooling housing 1, and the other side of the bottom end of the fixed bracket 6 is fixedly connected to the top end of the gear protective cover 5. A speed sensor body 7 is detachably arranged on the upper part of the fixed bracket 6. The fixed bracket 6 facilitates the operator to quickly insert the speed sensor body 7 and perform positioning operations.
[0021] Specifically, a groove 2 is opened inside the tooling housing 1. A driving motor 3 is fixedly arranged inside the groove 2, and the output end of the driving motor 3 penetrates through the tooling housing 1 and is fixedly connected to the speed measurement gear 4. The driving motor 3 rotates to drive the speed measurement gear 4 to rotate.
[0022] Furthermore, a motor driver 16 is fixedly arranged on one side of the inner wall of the groove 2, and the motor driver 16 is electrically connected to the driving motor 3. A battery body 17 is fixedly arranged on the other side of the inner wall of the groove 2. The battery body 17 is used to supply power to the motor. The motor driver 16 adjusts the rotation speed of the driving motor 3 to simulate working conditions at different rotation speeds.
[0023] Still further, a forward and reverse button 9 is fixedly arranged on one side of the top end of the tooling housing 1, and a power switch 11 is fixedly arranged on the other side of the top end of the tooling housing 1. The forward and reverse button 9 is used to control the forward and reverse rotation of the driving motor 3.
[0024] It should be noted that a frequency meter 10 is fixedly arranged on one side of the top end of the tooling housing 1, and a battery power level 14 is fixedly arranged on the other side of the top end of the tooling housing 1. The frequency meter 10 and the battery power level 14 can directly display the pulse frequency and the power level, which is convenient for the operator to observe and adjust.
[0025] It should be noted that a speed governor 13 is fixedly arranged on one side of the top end of the tooling housing 1, and a motor start / stop 15 is fixedly arranged on the other side of the top end of the tooling housing 1. The speed governor 13 controls the motor driver 16 to adjust the rotation speed of the driving motor 3 to simulate working conditions at different rotation speeds, and realizes the detection of abnormal faults of the speed sensor body 7.
[0026] It should be introduced that heat dissipation holes 8 are opened on the outer side of the tooling housing 1, and a handle 12 is fixedly arranged on the top end of the tooling housing 1.

[0028] Working principle: First, turn on the power switch 11 at the top of the tooling housing 1 to energize the tooling. Place the speed sensor body 7 on the fixed bracket 6, press the motor start / stop 15 button, and the motor start / stop 15 controls the driving motor 3 inside the control groove 2 to rotate. The rotation of the driving motor 3 drives the speed measurement gear 4 to rotate. Rotate the speed regulator 13, and the speed regulator 13 controls the motor driver 16 to adjust the rotation speed of the driving motor 3 to simulate working conditions at different rotation speeds, realizing the detection of abnormal faults of the speed sensor body 7. By vertically placing the end of the speed sensor body 7 directly above the speed measurement gear 4, during the rotation of the speed measurement gear 4, the speed sensor body 7 transmits analog signals to the BCU of this unit. The BCU monitors the speed and checks whether the speed data collected by the computer STOA3 software is greater than 10 KM / h. If the speed collected by the software is greater than 10 KM / h, it means that the functional state of the speed sensor body 7 is good; otherwise, on the contrary, the speed sensor body 7 needs to be replaced. The gear protective cover 5 is used to prevent the rotation of the speed measurement gear 4 from causing harm to the operator. The frequency meter 10 and the battery power 14 can directly display the pulse frequency and the power, facilitating the operator to observe and adjust. The forward / reverse button 9 is used to control the forward and reverse rotation of the driving motor 3. The handle 12 is used to facilitate the movement of the simulation auxiliary tooling. The heat dissipation holes 8 are used for heat dissipation. The battery body 17 is used to supply power to the motor.
