The brake pad body 1 includes a friction plate 11, a heat insulation plate 12, an adhesive 13, a back plate 14, and a sound insulation plate 15. The upper surface of the friction plate 11 is set to be frosted. Two grooves 111 distributed in mirror image are formed on the upper surface of the friction plate 11.

[0022] As Figures 2 - 6 shown in the figure, the present utility model provides a detection device for a wear-resistant automotive brake pad and a detection device, which includes a detection frame 2. A sliding plate 8 is slidably installed in the detection frame 2. An installation block 9 is fixedly installed on one side of the sliding plate 8. A telescopic block 10 is slidably installed in the installation block 9. A detection plate 101 is detachably installed on one side of the telescopic block 10. A limiting component 106 is installed on the telescopic block 10. The limiting component 106 includes two limiting blocks 1064 distributed in mirror image, and the limiting blocks 1064 are slidably installed in the internal cavity of the telescopic block 10. A pull rod 1062 is fixedly installed on one side of each of the two limiting blocks 1064 away from each other.

[0023] By adopting the above technical solution, the detection plate 101 is slid along the chute on the telescopic block 10. When the bottom end of the back of the detection plate 101 contacts the inclined surface of the limit block 1064, the detection plate 101 continues to slide downward and squeezes the limit block 1064 into the cavity of the telescopic block 10. When the detection plate 101 slides to the bottom end, the limit block 1064 is clamped into the card slot 1065 on the detection plate 101 under the resilience of the second spring 1063 to limit the detection plate 101. When it is necessary to remove the detection plate 101, manually pull the pull ring 1061, and pull the limit block 1064 out of the card slot 1065 of the detection plate 101 through the pull rod 1062, so that the detection plate 101 can be removed from the telescopic block 10.

[0024] Two expansion rods 104 distributed up and down are fixedly installed on one side of the telescopic block 10. An adjusting plate 107 is slidably installed in the installation block 9, and one end of the expansion rod 104 is fixedly connected to the adjusting plate 107.

The adjusting assembly 103 includes a threaded sleeve 1033, and the threaded sleeve 1033 is fixedly installed on one side of the adjusting plate 107. A lead screw 1032 is rotatably installed on the sliding plate 8, and the lead screw 1032 is threadedly inserted into the threaded sleeve 1033. One end of the lead screw 1032 is fixedly installed with a knob 1031.

[0025] By adopting the above technical solution, the knob 1031 is used to drive the lead screw 1032 to rotate. The lead screw 1032 drives the threaded sleeve 1033 to move. The threaded sleeve 1033 drives the adjusting plate 107 to move and adjust the position. The adjusting plate 107 drives the telescopic block 10 and the detection plate 101 to move and adjust the position. The detection plate 101 on the telescopic block 10 contacts the brake pad body 6, and as the continuous rotation squeezes the telescopic block 10 to contract into the installation block 9, and the first spring 105 in the installation block 9 pushes the detection plate 101 to always contact the brake pad body 6. The expansion rod 104 can improve the stability of the telescopic block 10.

[0026] A small gear 3 is rotatably installed on one side inside the detection frame 2. A mounting disc 5 is fixedly installed on one side of the small gear 3. A brake pad body 6 is detachably installed on the mounting disc 5. One end of the detection frame 2 is fixedly installed with a motor 102, and the output end of the motor 102 is fixedly connected to one side of the small gear 3. Two threaded rods 7 distributed symmetrically are rotatably installed in the detection frame 2, and the threaded rods 7 are threadedly inserted into the sliding plate 8. One end of each of the two threaded rods 7 is fixedly installed with a large gear 4, and the large gear 4 meshes with the small gear 3.

[0027] By adopting the above technical solution, the motor 102 is used to drive the small gear 3 to rotate. The small gear 3 drives the brake pad body 6 to rotate. At the same time, the small gear 3 drives the large gear 4 to rotate. The large gear 4 drives the threaded rod 7 to rotate. The threaded rod 7 drives the sliding plate 8 to move.

[0028] Working principle: When the utility model is in use, first install the brake pad main body 6 on the mounting plate 5, and slide the detection plate 101 along the chute on the telescopic block 10. When the bottom end of the back of the detection plate 101 contacts the inclined surface of the limiting block 1064, the detection plate 101 continues to slide downward and squeezes the limiting block 1064 into the cavity of the telescopic block 10. When the detection plate 101 slides to the bottom end, the limiting block 1064 is snapped into the card slot 1065 on the detection plate 101 under the resilience of the second spring 1063 to limit the detection plate 101 (when it is necessary to remove the detection plate 101, manually pull the pull ring 1061, and pull the limiting block 1064 out of the card slot 1065 of the detection plate 101 through the pull rod 1062, so that the detection plate 101 can be removed from the telescopic block 10). Then drive the lead screw 1032 to rotate by using the knob 1031. The lead screw 1032 drives the threaded sleeve 1033 to move. The threaded sleeve 1033 drives the adjusting plate 107 to move and adjust the position. The adjusting plate 107 drives the telescopic block 10 and the detection plate 101 to move and adjust the position. Then drive the small gear 3 to rotate by using the motor 102. The small gear 3 drives the brake pad main body 6 to rotate. At the same time, the small gear 3 drives the large gear 4 to rotate. The large gear 4 drives the threaded rod 7 to rotate. The threaded rod 7 drives the sliding plate 8 to move, so that the detection plate 101 on the telescopic block 10 contacts the brake pad main body 6, and as the continuous rotation squeezes the telescopic block 10 to contract into the mounting block 9, and the first spring 105 in the mounting block 9 pushes the detection plate 101 to always contact the brake pad main body 6. The telescopic rod 104 can improve the stability of the telescopic block 10.
