[0019] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0020] Embodiment: A vehicle brake pad wear resistance detection device, referring to Figures 1 to 4 , including a base 1, a mounting plate 2, a timer 3, a motor 4, a sleeve rod 5, a connecting rod 6, a wear-resistant block 7, an inner gear ring 8, a screw rod 9, a full gear 10, a pressure sensor 11 and a fixed screw 12. The base 1 is arranged in a "concave" shape, and a counterweight block is arranged at the bottom of the base 1 to increase the weight of the device to prevent displacement. A timer 3 is installed at the bottom center of the base 1, and a motor 4 for providing a power source is installed at the right center of the base 1 by bolt fixing. The output shaft of the motor 4 is connected to a sleeve rod 5, and a connecting rod 6 is slidably connected in the sleeve rod 5. The left end of the connecting rod 6 is connected to a The wear-resistant block 7 for wear detection has a connecting frame connected to the outer side of the sleeve rod 5, and an inner ring gear 8 is connected to the inner side of the connecting frame. The right end of the connecting rod 6 is connected to three screw rods 9 through threads, and the three screw rods 9 are distributed in a triangle. The right ends of the screw rods 9 are connected to full gears 10, and the full gears 10 are meshed with the inner ring gear 8. The upper side of the base 1 close to the wear-resistant block 7 is connected to a mounting plate 2, and the mounting plate 2 is provided with four fixing positions. A pressure sensor 11 is installed on the top of the mounting plate 2, and three fixed screws 12 are distributed in a triangle on the right side of the wear-resistant block 7. The fixed screws 12 are used to reduce wear with the screw rods 9.

[0021] When it is necessary to detect the automobile brake pad, first place the detection device at the designated work location, and install the automobile brake pad to be detected on the mounting plate 2. The mounting plate 2 is designed with four fixed positions. In this way, the detection device can detect different types of automobile brake pads. During the specific operation, four different types of automobile brake pads are installed at the corresponding positions of the mounting plate 2 respectively, and then, the inner ring gear 8 is rotated. Since the inner ring gear 8 is meshed with the full gear 10, when the inner ring gear 8 rotates, the full gear 10 will rotate with the screw rod 9, so that the connecting rod 6 moves to the left with the wear-resistant block 7 along the screw rod 9 until the wear-resistant block 7 contacts the automobile brake pad. At this time, the pressure sensor 11 can detect the pressure generated between the wear-resistant block 7 and the automobile brake pad, and the pressure value can be displayed by the pressure sensor 11. When the pressure value reaches the standard, the motor 4 is started, and the motor 4 provides power to drive the sleeve rod 5, the connecting rod 6 and the wear-resistant block 7 to rotate. The rotation of the wear-resistant block 7 can rub the surface of the automobile brake pad. At the same time, the timer 3 can also be started to record the wear detection time of the automobile brake pad. When the wear resistance test is completed, turn off the timer 3 and the motor 4. Then, rotate the inner gear ring 8 in the opposite direction to make the full gear 10 rotate in the opposite direction, so that the screw rod 9 drives the connecting rod 6 and the wear-resistant block 7 to move rightward, so that the wear-resistant block 7 is separated from the automobile brake pad, and finally the automobile brake pad after the test is removed from the mounting plate 2.
