Description

Technical Field

[0001] This utility model relates to the field of automotive brake testing technology, specifically an automotive brake testing bench. Background Technology

[0002] The ability of a car to stop within a short distance, maintain directional stability, and maintain a certain speed on a long downhill slope is called the car's braking ability. Parameters such as braking distance, braking deceleration, braking force, and braking time are tested to assess a car's braking performance. Currently, there are two methods for testing a car's braking performance: road testing and bench testing. A common flatbed brake testing bench includes a bench, a test plate on the bench, a weighing sensor, a limit device, and a brake calibration device.

[0003] Existing automotive brake testing benches on the market are not easy to adjust according to different vehicle wheelbases and tire sizes, resulting in significant limitations in vehicle testing. They may also only test braking by having the front or rear wheels in contact with the rollers, making them too simplistic and impractical. Therefore, corresponding improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an automotive brake testing bench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive brake inspection bench, comprising an inspection bench plate, the interior of which is hollow, and through slots are provided on both sides of the inner wall of the inspection bench plate. Electric push rods are installed on both sides of the inner walls of the two sets of through slots, and a first moving block and a second moving block are respectively installed at one end of each of the four sets of electric push rods. A sliding groove is provided inside the first moving block, and an electric bidirectional push rod is installed inside the sliding groove. A slider is installed at both ends of each of the electric bidirectional push rods, and a motor is installed on one side of each of the two sets of sliders. The output ends of each of the two sets of motors are connected to rotating rollers via a transmission shaft, and detection rollers are installed on the outer surfaces of each of the two sets of rotating rollers. One end of each of the two sets of rotating rollers is installed to a sliding seat via corresponding bearings, and one side of each of the two sets of sliding seats is respectively installed to one end of a bidirectional telescopic rod.

[0006] Preferably, a ramp is installed at one end of the inspection platform.

[0007] Preferably, an adjustment groove is provided on one side of the second movable block, and the bidirectional telescopic rod is installed inside the adjustment groove at a position close to the middle.

[0008] Preferably, the two sets of sliding seats are slidably connected at both ends inside the adjusting groove.

[0009] Preferably, the slider has a through hole at the position of the drive shaft, and one end of the drive shaft passes through the through hole into the slider.

[0010] Preferably, the first and second movable blocks are slidably connected to the through groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] By incorporating components such as an electric push rod, a first moving block, a second moving block, a slide, an electric bidirectional push rod, an adjusting groove, a slider, a motor, a rotating roller, a detection roller, a sliding seat, and a bidirectional telescopic rod, this design effectively solves the problems of existing automotive brake testing benches on the market. These benches are not easily adjustable according to different vehicle wheelbases and tire sizes, resulting in limited vehicle testing capabilities. Alternatively, they may only test the brakes by having the front or rear wheels in contact with the rollers, leading to a simplistic approach and poor practicality. Attached Figure Description

[0017] 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.

[0018] according to Figures 1-3As shown, the test bench 1 is hollow inside, and through slots 11 are provided on both sides of the inner wall of the test bench 1. Electric push rods 12 are installed on both sides of the inner wall of the two sets of through slots 11. A first moving block 13 and a second moving block 14 are respectively installed on one end of the four sets of electric push rods 12. The first moving block 13 and the second moving block 14 are slidably connected to the through slots 11. A sliding groove 15 is provided inside the first moving block 13, and an electric bidirectional push rod 16 is installed inside the sliding groove 15. A ramp 3 is installed on one end of the test bench 1.

[0019] Both ends of the electric bidirectional push rod 16 are equipped with sliders 2, and one side of each set of sliders 2 is equipped with a motor 21. The output ends of the two sets of motors 21 are connected to rotating rollers 22 via a drive shaft. The outer surfaces of the two sets of rotating rollers 22 are equipped with detection rollers 23. A through hole is opened inside the slider 2 at the position of the drive shaft, and one end of the drive shaft passes through the through hole into the inside of the slider 2. One end of each set of rotating rollers 22 is installed on a sliding seat 24 via corresponding bearings, and one side of each set of sliding seats 24 is installed on one end of the bidirectional telescopic rod 25. The two sets of sliding seats 24 are slidably connected inside the adjustment groove 17 near both ends. An adjustment groove 17 is opened on one side of the second moving block 14, and the bidirectional telescopic rod 25 is installed inside the adjustment groove 17 near the middle.

[0020] In use, the device consists of two sets, placed left and right respectively. This allows the left and right front and rear tires of a car to drive onto the top surface of the corresponding inspection platform 1 via the corresponding ramp 3. The left and right front and rear tires are then positioned between the corresponding sets of inspection rollers 23. The motor 21 is then started, causing the rotating roller 22 and inspection roller 23 to rotate accordingly, thus performing a braking test on the car's tires. Before the vehicle enters the top surface of the inspection platform 1, the user can adjust the inspection rollers 23 according to the car's wheelbase and tire size. Specifically, the user can first start the electric push rod 12, which will cause the two sets of first moving blocks 13 and two sets of second moving blocks to move. The 14 can slide accordingly inside the slide groove 15 and the adjustment groove 17 respectively, so that the distance between the two sets of detection rollers 23 located at both ends inside the inspection platform 1 matches the wheelbase of the vehicle to be tested. At this time, the electric push rod 12 can be closed, and the electric bidirectional push rod 16 can be started. Under the operation of the electric bidirectional push rod 16, the two sets of sliders 2 can move in opposite directions inside the slide groove 15, so that the rotating roller 22 and the detection roller 23 can move accordingly, so that the two sets of sliding seats 24 can move accordingly inside the adjustment groove 17. At the same time, the bidirectional telescopic rod 25 will extend and retract accordingly, so as to adjust the distance between the two sets of detection rollers 23, thereby adapting to different tire sizes.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
