Detailed Implementation

[0034] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0036] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

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

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

[0039] More specifically:

[0040] The simulated road surface testing mechanism 2 is connected to the base 1 via a first lifting assembly 3, which enables different tilting states of the simulated road surface testing mechanism 2. For example, the first lifting assembly 3 can be an electric cylinder with a FESTO proportional valve to regulate its extension and retraction. Three first lifting assemblies 3 are provided, located at both ends and the middle of the base 1, to ensure the stability of the simulated road surface testing mechanism 2 when tilted. The simulated road surface testing mechanism 2 includes three rotating shafts 201 connected to the movable ends of the first lifting assembly 3, an annular strip sleeved around all rotating shafts 201, and a motor connected to the rotating shafts 201. The annular strip includes a rough portion 202 of half its length and a smooth portion 203 of half its length. The rotating shafts 201 serve as drive wheels and driven wheels. The motor drives the drive wheels to rotate, and the interaction between the drive wheels and the contact surface of the annular strip through friction causes the annular strip to move. The annular strip gains power from the drive wheels and then returns to the drive wheels via the driven wheels, forming a cyclical motion. By setting the rotation speed of the drive wheel, the rough part 202 and the smooth part 203 on the annular belt can be switched.

[0041] A ring-shaped support 5 is positioned above the simulated road surface testing mechanism 2, and its length is greater than that of the mechanism 2. This ensures that the bicycle can undergo complete braking performance testing on the simulated road surface testing mechanism 2, and also facilitates bicycle repositioning. A traction mechanism 6 is slidably connected to the ring-shaped support 5 and used to suspend the bicycle so that its wheels contact the surface of the simulated road surface testing mechanism 2. Specifically, the ring-shaped support 5 has a groove 501 at its bottom. The traction mechanism 6 includes two second lifting components 601 slidably connected to the groove 501, and a connecting rod 602 hinged to the movable end of the second lifting components 601 and used to suspend the bicycle. The two lifting components 601 are located at the front and rear of the bicycle, respectively. The second lifting components 601 can be electric cylinders and are equipped with a FESTO proportional valve to regulate their extension and retraction. The end of the connecting rod 602 has a buckle to secure the bicycle, thus ensuring the bicycle's stability during testing.

[0042] The bicycle handlebars and brake levers are fitted with brake force rings 9. The inner wall of the brake force ring 9 has a movable bracket 901 that matches the bicycle's brake lever and is used to push the brake lever closer to or away from the handlebars. A telescopic assembly connects the movable bracket 901 and the inner wall of the brake force ring 9. The telescopic assembly can be an electric cylinder and is equipped with a FESTO proportional valve to regulate its extension and retraction. Its movable end is connected to the movable bracket 901. The electric cylinder drives the movable bracket 901 to extend / retract, causing the brake lever to move closer to or away from the handlebars, thus exhibiting different braking forces.

[0043] One end of the simulated road test mechanism 2 is also equipped with a transmitter 4 that provides power to the bicycle. The transmitter 4 is equipped with a fixing groove for fixing the bicycle wheel. 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 equipped with a water sprayer 7 that sprays water toward the surface of the annular strip to simulate a rainy day.

[0045] The simulated road test mechanism 2 has multiple sensor components 8 on one side to sense the speed and displacement of bicycles.

[0046] The bicycle brake testing system of this utility model also includes a control system, such as a PLC controller, which is electrically connected to the simulated road test mechanism 2, the transmitter 4, the water sprayer 7, the sensor assembly 8, and the brake force ring 9, so that the staff can monitor and adjust the parameters and collect bicycle brake performance data.

[0047] During operation, the tilt of the simulated road surface testing mechanism 2 is first adjusted via the first lifting component 3, such as... Figure 1 The horizontal state shown, or as Figure 4 The simulated road surface testing mechanism 2 can be in a downhill or uphill state. At the same time, the annular strip of the simulated road surface testing mechanism 2 can be adjusted so that the rough part 202 or the smooth part 203 is on top, to simulate smooth and rough road surfaces respectively; if simulating rain, water can be sprayed on the rough part 202 and the smooth part 203 by the water sprayer 7.

[0048] Next, the bicycle wheels 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 testing.

[0049] Next, the launcher 4 fires, causing the bicycle to enter the simulated road test mechanism 2 at a certain initial velocity.

[0050] Next, activate brake force ring 9 to provide braking force.

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

[0052] The bicycle brake testing system provided by this utility model can simulate various conditions, such as uphill, downhill, smooth road, rough road, and rainy weather. The bicycle can be reset at any time via the ring bracket 5 to test brake performance under different parameter conditions. Due to the flexibility of the second lifting component, it can be adapted to test the brake performance of bicycles of various sizes, making it widely applicable.

[0053] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
