An external bracket 10-4 for installing the speed sensor 10-3 is detachably provided on the outside of the rear brake caliper of the motorcycle 10. The test surface of the speed sensor 10-3 faces the magnetic gear ring 10-2. The speed sensor 10-3 is connected to the vehicle speed test module 11 through the frequency acquisition module 12.

[0038] In this embodiment, during actual use, a threaded connecting rod 6-6 is provided on the clamp 6-5, and a threaded hole matching the threaded connecting rod 6-6 is provided in the other end of the connecting rod 6-4, so that the clamp 6-5 and the connecting rod 6-4 can be detachably connected, thereby facilitating the adjustment of the clamp 6-5 structure to adapt to different bumper 9 structures.

[0039] In this embodiment, in actual use, the shape of the clamp 6 - 5 is not limited as long as it adapts to the structure of the bumper 9 .

[0040] In this embodiment, the baffle 4 is provided to enclose and form a bottom groove to accommodate the hanger 7, the first connecting rod 5 and the second connecting rod 6 after they are contracted; on the other hand, it can also form a bottom contact surface at the bottom for easy placement.

[0041] In this embodiment, the suspension rod 7 and the elastic band 8 are provided so as to retract the first connecting rod 5 and the second connecting rod 6 when not in use, and rotate around the hinge seat 6-1 through the ball head 6-2 until the first connecting rod 5 and the second connecting rod 6 are horizontally arranged along the bottom of the external test box 1, and the first connecting rod 5 and the second connecting rod 6 are tied together by the elastic band 8 to achieve the storage of the first connecting rod 5 and the second connecting rod 6.

[0043] In this embodiment, in actual use, the rear brake caliper of the motorcycle 10 is not shown in the figure, and those skilled in the art are aware of it.

[0044] In this embodiment, in actual use, the installation position and shape of the outer bracket 10-4 are not limited and can be adjusted according to actual needs to accommodate the installation of the speed sensor 10-3. The outer bracket 10-4 is detachably connected by bolts for easy disassembly and assembly. During the installation process, the outer bracket 10-4 and the speed sensor 10-3 remain in place, and only the magnetic gear ring 10-2 and the subsequent axle 10-1 rotate to achieve speed detection.

[0045] In this embodiment, in actual use, the vehicle speed test module 11 adopts the VBOX data acquisition module of VBOX3i.

[0046] In this embodiment, the vehicle speed testing module 11 is provided for non-contact measurement based on GPS technology, so as to obtain the vehicle speed of the motorcycle 10 .

[0047] In this embodiment, in actual use, the speed sensor 10 - 3 may refer to a Hall-type speed sensor.

[0048] In this embodiment, the gap between the speed sensor 10-3 and the magnetic gear ring 10-2 is 1mm to 2mm. In actual use, when the teeth of the magnetic gear ring 10-2 are aligned with the speed sensor 10-3, the speed sensor 10-3 outputs a high level; conversely, when the neutral position of the magnetic gear ring 10-2 is aligned with the speed sensor 10-3, the output is a low level, and a pulse signal is obtained.

[0049] In this embodiment, in actual use, the frequency acquisition module 14 is a Racelogic VBOX frequency input module FIM03.

[0050] In this embodiment, the pulse signal output by the speed sensor 10 - 3 is sent to the frequency acquisition module 14 , and the frequency acquisition module 14 processes the pulse signal output by the speed sensor 10 - 3 to obtain the rear wheel speed, and then sends it to the vehicle speed test module 11 .

[0051] In this embodiment, during the actual connection process, the output end of the speed sensor 10 - 3 is connected to the input end of the frequency acquisition module 14 , and the CAN interface of the frequency acquisition module 14 is connected to the CAN interface of the vehicle speed test module 11 through the CAN bus.

[0052] In this embodiment, the microcontroller 13 can adopt a STC12C5A48S2 single-chip microcomputer, which is provided with a DB9 serial port. The RS-232 serial interface of the vehicle speed test module 11 is connected to the DB9 serial port through a serial port line, thereby realizing a wired connection between the microcontroller 13 and the vehicle speed test module 11.

[0053] In this embodiment, the display screen 2 can refer to the 4ZX12232C display screen.

[0054] In this embodiment, the display screen 2 and the buzzer 3 are respectively connected to the IO ports of the microcontroller 13, and the conventional connection in the art can be referred to.

[0055] In this embodiment, the magnetic gear ring 10 - 2 and the rear wheel axle 10 - 1 are coaxially arranged and rotate synchronously.

[0056] In this embodiment, a display screen 2 is provided to display the rear wheel speed and the whole vehicle speed for observation purposes.

[0057] When the utility model is used specifically, during the rotation of the magnetic gear ring 10-2 and the subsequent wheel axle 10-1, i.e., the rear wheel, the speed sensor 10-3 tests the speed of the rear wheel and outputs a pulse signal to send to the frequency acquisition module 14. The frequency acquisition module 14 processes the pulse signal to obtain the rear wheel speed and sends it to the vehicle speed test module 11. At the same time, the vehicle speed test module 11 tests the vehicle speed of the motorcycle 10. The vehicle speed test module 11 sends the vehicle speed and the rear wheel speed to the microcontroller 13 through the serial port. The microcontroller 13 multiplies the received rear wheel speed by the wheel diameter and the pi and divides the result by 60 to obtain the rear wheel speed. When the rear wheel speed is greater than the vehicle speed, the microcontroller 13 sends a high-level signal to the buzzer 3, and the buzzer 3 alarms.

[0058] If the rear wheel speed is greater than the vehicle speed when the buzzer 3 alarms, it means that the rear wheel of the motorcycle 10 is slipping. At this time, if the driver keeps the current throttle action unchanged, the buzzer 3 stops alarming, and the rear wheel speed is equal to the vehicle speed. This means that the motorcycle TCS starts to work and reduces the fuel injection amount to reduce the rear wheel speed to the vehicle speed, thereby testing that the motorcycle TCS performance is normal.

[0059] In summary, the utility model has a simple structure, and can provide an objective test for determining whether the TCS of a motorcycle works normally by testing the rear wheel rotation speed and the vehicle speed through an external device, and is easy to reuse.

[0060] The above is only a preferred embodiment of the present invention and does not constitute any limitation to the present invention. Any simple modification, change and equivalent structural change made to the above embodiments according to the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
