[0002] Automotive braking performance testing equipment is used to test the braking performance of a vehicle. An automotive braking system refers to a series of specialized devices that apply a certain force to certain parts of a vehicle (mainly the wheels), thereby forcibly braking it to a certain degree. The functions of the braking system are: to force a moving vehicle to decelerate or even stop it as required by the driver; to keep a parked vehicle stable under various road conditions (including on slopes); and to maintain a stable speed for a vehicle traveling downhill.

[0003] For example, the authorized patent with publication number CN208505624U (Automotive Brake Testing Stand): This patent relates to the field of automotive testing equipment and solves the problem of the inability to adjust the installation height of automotive brake testing stands. It includes a frame, roller assemblies, a drive motor, and a third roller. The roller assemblies are arranged in two pairs symmetrically within the frame. Each pair of roller assemblies includes a main roller and an auxiliary roller. The main roller and auxiliary roller are respectively mounted within the frame via roller bearings and bearing seats, and the axes of the corresponding two rollers are parallel. One end of the main roller is connected to the drive motor. The main roller and auxiliary roller are connected via chain drive. The third roller is positioned between the main roller and auxiliary roller, with its axis parallel to both. One end of the third roller is connected to a speed sensor. An adjustment device for adjusting the installation height of the automotive brake testing stand is provided on the bottom outer side of the frame.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-5 This utility model provides an embodiment of an automotive braking performance testing device, comprising a full-line speed measuring guard plate 3, a full-line braking test plate 5, and a speed measuring pad 7. The speed measuring pad 7 has two full-line braking test plates 5 positioned on either side of its top center. These two symmetrically arranged full-line braking test plates 5 allow for comprehensive speed measurement of both tires, ensuring accurate detection of speed changes. A limiting top plate 1 is provided between the two full-line braking test plates 5 to reinforce their support. Adjustable full-line speed measuring guard plates 3 are located at the top and bottom of both sides of the full-line braking test plate 5, enabling full-process braking performance testing. The speed measuring pad 7 is locked to the ground 13 via multiple pins 12 at its bottom, facilitating connection control between the speed measuring pad 7 and the ground 13.

[0018] Furthermore, the comprehensive brake detection plate 5 includes a protective cover 9, a crash barrier 10, a main control panel 11, and a second speed sensor head 6. The crash barrier 10 is located on the outside of the comprehensive brake detection plate 5 and provides crash protection for the comprehensive brake detection plate 5. The protective cover 9 is located on the outside of the crash barrier 10 and provides safety protection for the crash barrier 10. The main control panel 11 is located on the front of the protective cover 9. Multiple second speed sensors 6 are evenly distributed on the inside of the comprehensive brake detection plate 5. Both the first speed sensor head 4 and the second speed sensor head 6 are HT3000 models and are used to detect the vehicle speed in real time.

[0019] Furthermore, the brake full detection plate 5 is provided with ear brackets 2 at the upper and lower positions on both sides. The ear brackets 2 are hinged to the connecting ears 14 at the end of the full-line speed measuring guard plate 3 and are locked and fixed by the lock head thread. The ear brackets 2 are convenient to be hinged to the connecting ears 14.

[0020] Furthermore, the speed measuring guard plate 3 includes a first speed measuring sensor head 4 and a secondary control board 8; multiple first speed measuring sensors 4 are evenly arranged on the inner side of the speed measuring guard plate 3, and the secondary control board 8 is arranged on the outer side of the speed measuring guard plate 3. The secondary control board 8 is used to receive control signals from the main control panel 11 and then control the multiple first speed measuring sensors 4.

[0021] Furthermore, both brake full detection plates 5 are integrated with the speed measuring pad 7, and the brake full detection plates 5 and the limit top plate 1 are integrated into one structure. The integrated design makes the equipment more stable in use.

[0022] Furthermore, the output end of the first speed sensor 4 is electrically connected to the input end of the secondary control board 8, and the output end of the second speed sensor 6 is electrically connected to the input end of the main control panel 11. The inner cavities of the brake full detection board 5 and the full-line speed protection board 3 are equipped with power distribution core boards. The information detected by the first speed sensor 4 is transmitted to the secondary control board 8 and then transmitted to the main control panel 11 through the secondary control board 8.

[0023] Working principle: In use, the speed measuring pad 7 is fixed to the ground 13 of the detection area by the pin 12. Multiple full-line speed measuring guard plates 3 are manually unfolded in sequence. The brake full detection plate 5 and multiple full-line speed measuring guard plates 3 are opened simultaneously by the main control panel 11. When the vehicle to be tested drives onto the speed measuring pad 7, the vehicle brakes simultaneously. At this time, the vehicle speed is detected in real time by multiple first speed measuring heads 4 on the inside of the full-line speed measuring guard plate 3, and the vehicle has stopped by multiple second speed measuring heads 6 on the inside of the brake full detection plate 5. The detection data is fed back to the auxiliary control board 8 and the main control panel 11 respectively. After analyzing and calculating the changes in braking time and vehicle speed, the detection results are obtained and displayed on the main control panel 11.
