[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figures 1 to 6 An adjustable ramp for automobile brake testing is shown, comprising:

[0026] A fixed base 1, a test ramp 2 is provided at the top of the fixed base 1, a connecting block 10 is fixedly provided on both sides of the front end of the fixed base 1, the front end of the test ramp 2 is arranged between the two connecting blocks 10 and is rotatably connected to the two connecting blocks 10 through a rotating shaft;

[0027] The first movable block 3 is arranged at the top of the fixed base 1, the top of the first movable block 3 is an inclined surface, an adjusting component is arranged between the first movable block 3 and the fixed base 1, two support plates 4 are arranged at the top of the first movable block 3, two capstan seats 5 are fixedly arranged at the bottom end of the test ramp plate 2, the top of the support plate 4 and the bottom end of the test ramp plate 2 are rotatably connected through the capstan seat 5, a first movable groove 6 is opened at the top of the first movable block 3, the bottom end of the support plate 4 extends to the inside of the first movable groove 6, two rotating rollers 7 are rotatably connected between the two support plates 4, the bottom end of the rotating roller 7 contacts with the bottom end of the first movable groove 6, both side walls inside the first movable groove 6 are provided with limiting slide grooves 8, limiting slide grooves 8 are provided with limiting sliders 9, and two limiting sliders 9 are respectively fixedly connected to the outer sides of the bottom ends of the two support plates 4.

[0028] A connecting inclined block 11 is fixedly provided at the front end of the fixed base 1 , and the connecting inclined block 11 is arranged at the front side of the test ramp plate 2 .

[0029] The adjustment component includes a second movable groove 12 opened at the top of the fixed base 1, a second movable block 13 is arranged inside the second movable groove 12, the top of the second movable block 13 is fixedly connected to the bottom of the first movable block 3, a threaded rod 14 is arranged inside the second movable groove 12, one end of the threaded rod 14 passes through the second movable block 13 and extends to the rear end of the fixed base 1, both ends of the threaded rod 14 are rotatably connected to the front and rear ends of the second movable groove 12 through bearings, the threaded rod 14 and the second movable block 13 are connected by threads, a motor 15 is fixedly arranged at the rear end of the fixed base 1, and the output shaft of the motor 15 is fixedly connected to one end of the threaded rod 14.

[0030] Start the motor 15, and the output shaft of the motor 15 drives the threaded rod 14 to rotate. Since the threaded rod 14 is threadedly connected to the second movable block 13, the second movable block 13 moves back and forth inside the second movable groove 12 as the threaded rod 14 rotates, and the second movable block 13 drives the first movable block 3 to move forward and backward. When the first movable block 3 moves forward, the high point of the inclined surface on the first movable block 3 moves to the bottom end of the support plate 4, and the support plate 4 will rise. The support plate 4 drives one end of the test ramp plate 2 to rise, so that the inclination angle of the test ramp plate 2 can be increased. Similarly, when the first movable block 3 moves backward, the low point of the inclined surface on the first movable block 3 moves to the bottom end of the support plate 4, so that the height of the support plate 4 is reduced, and the support plate 4 drives one end of the test ramp plate 2 to lower, so that the inclination angle of the test ramp plate 2 can be reduced.

[0031] The utility model drives the first movable block 3 to move to adjust the height of the support plate 4 through an adjusting component, and then the height of one end of the test ramp plate 2 can be adjusted.

It has high applicability and avoids the situation of setting up multiple ramps in the test site, saving space and resources, and having a good use effect. This embodiment specifically solves the problem that when the automobile brake test ramp in the prior art is actually used, most of the test ramps are slopes with fixed inclination angles, and such test ramps cannot adjust the ramp angle. When it is necessary to perform brake tests on ramps with different inclinations on the automobile, different test ramps need to be used, which will result in more ramps in the test site, occupying more space, and the use effect is not good enough.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
