[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1-3 An auxiliary tooling for testing an automotive braking system includes a baffle mechanism 1, a measuring rod mechanism 2, and a brake point indication mechanism 3. Each baffle mechanism 1 includes an L-shaped baffle 101. A second groove 107 is provided on one side of the L-shaped baffle 101, and a second slider 106 corresponding to the second groove 107 is fixedly connected to the other side of the L-shaped baffle 101. By providing the second groove 107 and the second slider 106 on both sides of the L-shaped baffle 101, it is convenient to combine the L-shaped baffle 101 according to experimental requirements and place it at both ends of the test vehicle. This helps to support and protect the vehicle, prevent the vehicle from overturning due to sudden braking, improve the safety of the experiment, and reduce experimental losses.

[0026] A locking block 102 is rotatably connected to one side of the top of the L-shaped baffle 101, and a limiting rod 103 is fixedly connected to the other side of the top of the L-shaped baffle 101. The locking block 102 is provided with a locking groove that matches the limiting rod 103. By setting a rotatable locking block 102 and a matching limiting rod 103, the stability of the connection between the L-shaped baffles 101 is enhanced.

[0027] The front end of the L-shaped baffle 101 is provided with two sets of first slide grooves 104. One set of first slide grooves 104 is 130 cm above the ground, and the other set of first slide grooves 104 is 150 cm above the ground. The bottom end of both sets of first slide grooves 104 is provided with a scale 105. By setting two sets of first slide grooves 104 at different heights, the height of the measuring rod mechanism can be adjusted according to different vehicle models. The measuring rod mechanism 2 at a height of 130 cm can be used to measure the braking distance of sedan models, and the measuring rod mechanism 2 at a height of 150 cm can be used to measure the braking distance of off-road models. By setting a scale on the surface of the L-shaped baffle 101, it is convenient for the staff to measure the excessive braking distance.

[0028] The L-shaped baffle 101 has through grooves 108 at its four corners at the bottom, and ground nails 109 are slidably connected to the through grooves 108. By setting the ground nails 109 and the through grooves 108, it is easy to connect the L-shaped baffle 101 to the ground, which helps to increase the support of the L-shaped baffle 101. When the vehicle rolls over, it can be supported to prevent the vehicle from rolling over, which helps to protect the staff.

[0029] The measuring rod mechanism 2 includes a mounting rod 201, with first sliders 202 fixedly connected to both ends of the mounting rod 201. The first sliders 202 are slidably connected to the first groove 104. A sponge sleeve 203 is fixedly connected to the outer wall of the mounting rod 201, and several sets of evenly distributed suction cups 204 are fixedly connected to the sponge sleeve 203. By setting the first sliders 202, which can slide along the first groove 104, it is convenient to measure the distance exceeding the preset braking point. By setting the sponge sleeve 203 on the outside of the mounting rod 201, it is beneficial to prevent damage when the car comes into contact with the mounting rod 201. By setting the suction cups 204 on the outside of the sponge sleeve 203, when the car comes into contact with the mounting rod 201, the suction cups 204 connect the mounting rod 201 to the windshield of the car, which is beneficial to prevent the impact force generated when the two come into contact from causing the mounting rod 201 to slide. The operator can measure the distance exceeded by observing the distance between the initial placement point and the final stopping point of the measuring rod mechanism 2, which is beneficial to improving the accuracy of the measurement.

[0030] In this embodiment, by providing second sliding grooves 107 and second sliding blocks 106 on both sides of the L-shaped baffle 101, it is convenient to combine the L-shaped baffle 101 according to experimental requirements and place it at both ends of the test vehicle, which is beneficial for supporting and protecting the vehicle. By providing ground nails 109 and through grooves 108, it is convenient to connect the L-shaped baffle 101 to the ground, which is beneficial for increasing the support of the L-shaped baffle 101. When the vehicle rolls over, it is supported to prevent the vehicle from rolling over, which is beneficial for protecting the staff. By providing two sets of first sliding grooves 104 with different heights, the height of the measuring rod mechanism can be adjusted according to different vehicle models. The measuring rod mechanism 2 with a height of 130 cm can be used to measure the braking distance of sedan models, and the measuring rod mechanism 2 with a height of 150 cm can be used to measure the braking distance of off-road models. By providing scales on the surface of the L-shaped baffle 101, it is convenient for the staff to measure the excessive braking distance, which is beneficial for improving the accuracy of the measurement.

[0031] Example 2:

[0032] Please see Figure 1-4 This embodiment provides a technical solution based on embodiment one: the brake point indication mechanism 3 includes a U-shaped connecting rod 301, the bottom end of which is fixedly connected to a mounting block 302, and each set of mounting blocks 302 is fixedly connected to four corners at the bottom end of each set of mounting blocks 302. By setting the U-shaped connecting rod 301, two sets of mounting blocks 302 are connected together. By setting the four corners at the bottom end of the mounting blocks 302, it is convenient for the staff to move the brake point indication mechanism 3.

[0033] An infrared sensor 304 is fixedly connected to one set of mounting blocks 302, and an infrared receiver 305 and a speaker body 306 are fixedly connected to the other set of mounting blocks 302. The infrared sensor 304, infrared receiver 305, and speaker body 306 are all fixedly connected to an external power supply. The infrared sensor 304, infrared receiver 305, and speaker body 306 can all be controlled by a PLC. When the test is started, the power is turned on, and the infrared sensor 304 emits infrared light, which is received by the infrared receiver 305. When a vehicle passes by, the infrared light is blocked. When the infrared receiver 305 can no longer receive infrared light, it outputs a signal to control the speaker body 306 to emit an alarm sound, prompting the test driver to apply the brakes. Compared with placing an observation object and having the test driver subjectively judge the braking point, the test results are more accurate.

[0034] In this embodiment, when the test is started, the power is turned on, and the infrared sensor 304 emits infrared light, which is received by the infrared receiver 305. When a vehicle passes by, the infrared light is blocked. When the infrared receiver 305 can no longer receive infrared light, it outputs a signal to control the speaker body 306 to emit an alarm sound, prompting the test driver to step on the brake. Compared with placing an observation object and having the test driver subjectively judge the braking point, the test results are more accurate. By setting a U-shaped connecting rod 301 to connect the two sets of mounting blocks 302 together, and by setting universal wheels 303 at the four corners of the bottom end of the mounting blocks 302, the ease of movement of the brake point indication mechanism 3 is improved.
