[0002] With the development of electric vehicles on the market, more and more electric vehicles are on the road. In order to improve the driving safety of electric vehicles, electric vehicles need to be equipped with disc brakes. Disc brakes, also known as disc brakes, are a braking system consisting of a brake disc connected to the wheel and a brake caliper set at the edge of the brake disc. The brake pads inside the brake caliper are pushed by high-pressure brake oil to clamp the brake disc, thereby producing a braking effect.

The traditional testing method is very simple, and can only remove and replace the next disc brake after the single disc brake is tested. The detection efficiency is low, and it is impossible to truly simulate the actual status of different vehicles under driving and braking, resulting in insufficient simulation.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The device shown is a rapid simulation detection device for the use environment of electric vehicle disc brakes, comprising a bottom-mounted detection box 1, a drive motor 2 and an air pump 3. An arc-shaped detection chamber 4 with an upper end opening is provided inside the bottom-mounted detection box 1. A vertical assembly disk 5 controlled by the drive motor 2 is movably mounted inside the arc-shaped detection chamber 4. An internal lateral mounting notch 6 for mounting a disc brake disc is provided on the side wall of the vertical assembly disk 5. An embedded lateral fixing groove 7 for mounting a disc brake caliper is provided on the inner side surface of the arc-shaped detection chamber 4. An electrically controlled telescopic transmission shaft 8 cooperating with the drive motor 2 is installed on the inner side surface of the arc-shaped detection chamber 4. Two embedded temperature probes 9 and an optical recognition probe 10 are installed on the inner side surface of the arc-shaped detection chamber 4.

[0032] In order to adjust the flow direction of the internal air, a circular embedded adjustment groove 11 is opened on the inner side of the arc-shaped detection chamber 4, and an electrically controlled flow guide arm 12 that cooperates with the air pump 3 is installed inside the circular embedded adjustment groove 11.

[0033] Working principle: people install the disc brake disc inside the internal lateral mounting notch 6, and then start the device. The vertical assembly plate 5 rotates the disc brake disc to the inside of the arc-shaped detection chamber 4, and the optical recognition probe 10 at the opening position performs preliminary optical recognition and recording of its surface. When the disc brake disc rotates to the disc brake caliper position, the disc brake caliper extends to the periphery of the disc brake disc through the telescopic adjustment strut on the side wall, and then the electrically controlled telescopic transmission shaft 8 is inserted into the center of the disc brake disc to drive the disc brake disc to rotate at high speed. When the speed reaches the set speed, the detection is started, the disc brake caliper starts to clamp the disc brake disc, and the braking is started. Then the embedded temperature probe 9 starts to detect the temperature of each position of the disc brake disc. At the same time, the vacuum pump 3 blows air to the surface of the disc brake disc through the electrically controlled guide arm 12 to simulate the airflow changes of the car during driving. Then, after complete braking, the disc brake caliper and the electrically controlled telescopic transmission shaft 8 are reset, and the vertical assembly plate 5 drives the disc brake disc to rotate, and then optically detected by the optical recognition probe 10, and then compared with the preliminary optical recognition record to determine the changes on its surface.

[0034] In order to cooperate with the lateral limit, a plurality of embedded limit struts 13 are installed on the inner side of the arc-shaped detection chamber 4, and an internal limit through hole 14 cooperating with the embedded limit struts 13 is opened inside the vertical assembly plate 5.

[0035] In order to cooperate with the bottom support and drive of the vertical assembly plate 5, a bottom support wheel 15 and a bottom drive wheel 16 are movably installed on the inner bottom surface of the arc-shaped detection chamber 4.

[0036] The bottom driving wheel 16 rotates, thereby driving the vertical assembly plate 5 to rotate on the bottom-mounted detection box 1 .

The protruding end of the electrically controlled adjustment strut 83 is fixedly connected to the outer wall of the telescopic sleeve 82 through a lateral fixed frame 84.

[0038] The electrically controlled regulating strut 83 is extended, thereby driving the telescopic sleeve 82 to slide and adjust along the outer side of the main driving sleeve 81 .

[0039] In order to cooperate with the rotation adjustment and adjust the internal control flow, the electrically controlled flow guide arm 12 includes an inner exhaust pipe 121 fixedly connected to the air outlet of the vacuum pump 3, a lateral flow guide pipe 122 with an inverted L-shaped structure sleeved on the outer opening of the inner exhaust pipe 121, an embedded adjustment motor 123 fixed on the inner side surface of the circular embedded adjustment groove 11, an external driven gear 124 axially sleeved on the outer side surface of the lateral flow guide pipe 122, an external driving gear 125 axially fixed on the adjustment shaft of the embedded adjustment motor 123 and an inclined flow guide nozzle 126 fixed on the outer air outlet of the lateral flow guide pipe 122.

[0040] The embedded regulating motor 123 drives the external driving gear 125 to control the meshing external driven gear 124 to rotate, thereby controlling the lateral air guide 122 to rotate, thereby adjusting the direction of air flow, and adjusting the air outlet position by changing the flow direction.

[0041] In order to facilitate fixing and loading and unloading, the inner side surface of the internal lateral mounting notch 6 is movably equipped with an internal mounting flange 17 for fixing the disc brake disc. The disc brake disc is sleeved on the threaded rod 18 on the internal mounting flange 17 through the internal mounting hole and fixed to the internal mounting flange 17 with bolts. The center position of the internal mounting flange 17 is provided with a central transmission sleeve 19 that cooperates with the telescopic sleeve 8.

[0042] People now put the disc brake disc on the threaded rod 18, and then tighten the locking bolt threaded on the threaded rod 18 to fix the disc brake disc; disassembly is the reverse operation.

[0043] The telescopic sleeve 8 is inserted into the middle transmission sleeve 19 to drive the disc brake disc to rotate.

[0044] In order to facilitate accurate positioning, an infrared positioning probe 20 is fixedly mounted on the end of the embedded limiting support rod 13 .

[0045] The position of the internal limit hole 14 is detected by the infrared positioning probe 20, and then the embedded limit support rod 13 is controlled to extend and the extended end is controlled to be inserted into the internal limit hole 14, thereby fixing the angle of the vertical assembly plate 5 and ensuring stability during the detection process.

[0046] In order to more intuitively display the test results, a status display light 21 is fixedly mounted on the upper surface of the bottom-mounted test box 1 .

[0047] When the test result is qualified, the status display light 21 displays green; when the test result is unqualified, the status display light 21 displays red, which is convenient for people to judge the test result.

[0048] In order to cooperate with the detection of the surface condition of the disc brake disc, a built-in dust removal device 22 is installed on the inner side of the arc-shaped detection chamber 4 between the embedded temperature probe 9 and the optical recognition probe 10.

[0049] An installation slot is provided on the side wall of the bottom-mounted detection box 1, and the built-in dust removal device 22 includes a dust collecting box fixed in the installation slot, a metal filter box fixed on the top surface of the dust collecting box, and a lateral exhaust pipe fixed on the outer surface of the dust collecting box.

[0050] The lateral air suction pipe is fixedly connected to the air inlet pipe of the air suction pump 3 . The air suction pump 3 draws dust into the circular embedded adjustment groove 11 by suction, and then returns the air to the inside of the electrically controlled guide arm 12 .
