[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0037] In the following embodiments, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0038] like Figures 1 to 5 As shown, a bicycle brake test system includes: a base 1, a simulated road surface test mechanism 2, a first lifting component 3, a transmitter 4, a ring bracket 5, a traction mechanism 6, a sprinkler 7, a sensor component 8, and a brake force ring 9.

[0039] More specifically:

[0040] The simulated road surface test mechanism 2 is connected to the base 1 through the first lifting assembly 3, and different tilting conditions of the simulated road surface test mechanism 2 are realized through the first lifting assembly 3. Exemplarily, the first lifting assembly 3 can be an electric cylinder, and a FESTO proportional valve is provided to control the telescopic condition. The first lifting assembly 3 is provided with three, which are respectively located at the two ends and the middle of the base 1 to ensure the stability of the simulated road surface test mechanism 2 when tilted. The simulated road surface test mechanism 2 includes three rotating shafts 201 connected to the movable ends of the first lifting assembly 3, an annular strip sleeved outside all the rotating shafts 201, and a motor connected to the rotating shaft 201. The annular strip includes a rough part 202 of 1 / 2 length and a smooth part 203 of 1 / 2 length. The rotating shaft 201 is a driving wheel and a driven wheel. The driving wheel is driven to rotate by the motor, and the driving wheel moves the annular strip through the interaction between the friction force and the contact surface of the annular strip. The annular strip obtains power on the driving wheel, and then returns to the driving wheel through the driven wheel, forming a repetitive movement. By setting the number of revolutions of the driving wheel, the rough portion 202 and the smooth portion 203 on the annular strip can be replaced.

[0041] The annular bracket 5 is arranged above the simulated road surface test mechanism 2, and its length is greater than the length of the simulated road surface test mechanism 2 to ensure that the bicycle can be completely tested for braking performance on the simulated road surface test mechanism 2. In addition, it is also convenient for the bicycle to be reset. The traction mechanism 6 is slidably connected to the annular bracket 5 and is used to suspend the bicycle so that the wheels of the bicycle are in contact with the surface of the simulated road surface test mechanism 2. Specifically, a slide groove 501 is provided at the bottom of the annular bracket 5, and the traction mechanism 6 includes two second lifting components 601 slidably connected to the slide groove 501, and a connecting rod 602 hinged to the movable end of the second lifting component 601 and used to suspend the bicycle. The two lifting components 601 are respectively located at the front and rear of the bicycle. The second lifting component 601 can be an electric cylinder and is provided with a FESTO proportional valve to adjust the telescopic situation. The end of the connecting rod 602 is provided with a buckle for fixing the bicycle, so that the bicycle can maintain stability during the test.

[0042] The handlebar and brake handle of the bicycle are provided with a brake force ring 9, and the inner wall of the brake force ring 9 is provided with a movable bracket 901 which matches the brake handle of the bicycle and is used to push the brake handle close to or away from the handlebar, and a telescopic component connecting the movable bracket 901 and the inner wall of the brake force ring 9. The telescopic component can be an electric cylinder, and is provided with a FESTO proportional valve to control the telescopic situation. Its movable end is connected to the movable bracket 901, and the movable bracket 901 is driven to extend / contract through the electric cylinder, so that the brake handle is close to or away from the handlebar, and different braking forces are exhibited.

[0043] One end of the simulated road surface testing mechanism 2 is also provided with a transmitter 4 for providing power for the bicycle. A fixing groove for fixing the bicycle wheel is provided on the transmitter 4. When the transmitter 4 is not working, the bicycle can be fixed at the transmitter 4.

[0044] The other end of the simulated road surface testing mechanism 2 is also provided with a sprinkler 7 for spraying water toward the surface of the annular strip to simulate the scene of a rainy day.

[0045] A plurality of sensor components 8 for sensing the speed and displacement of a bicycle are disposed on one side of the simulated road surface testing mechanism 2 .

[0046] The bicycle brake test system of the present invention also includes a control system electrically connected to the simulated road test mechanism 2, the transmitter 4, the sprinkler 7, the sensor assembly 8, and the brake force ring 9, such as a PLC controller, which is convenient for staff to monitor and adjust parameters and collect bicycle brake performance data.

[0047] During operation, the inclination of the simulated road surface testing mechanism 2 is first adjusted by the first lifting assembly 3, such as Figure 1 The horizontal state shown, or Figure 4 The simulated road surface test mechanism 2 can be in a downhill tilt state or an uphill state. At the same time, the annular strip of the simulated road surface test mechanism 2 is adjusted to have the rough portion 202 on the top or the smooth portion 203 on the top to simulate a smooth road surface and a rough road surface respectively; if it is a simulated rainy day, water can be sprayed on the rough portion 202 and the smooth portion 203 by the sprinkler 7.

[0048] Next, the wheels of the bicycle are fixed to the transmitter 4, and the connecting rod 602 fixes the front and rear of the bicycle to ensure the stability of the bicycle during detection.

[0049] Next, the launcher 4 launches, so that the bicycle enters the simulated road test mechanism 2 at a certain initial speed.

[0050] Next, the brake force ring 9 is activated to provide braking force.

[0051] Finally, the speed and displacement of the bicycle are sensed and recorded by the sensor assembly 8 .

[0052] The bicycle brake test system provided by the present invention can simulate various situations, such as uphill, downhill, smooth road, rough road, rainy day, etc., and the bicycle can be reset at any time through the annular bracket 5, so as to test the brake performance under different parameter conditions. Due to the flexibility of the second lifting assembly, it can be adapted to the brake performance test of bicycles of various sizes, and has a wide range of applications.

[0053] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
