Description

Technical Field

[0001] This invention relates to the field of electric vehicle disc brake testing technology, and in particular to a rapid simulation testing device for the operating environment of electric vehicle disc brakes. Background Technology

[0002] With the development of electric vehicles on the market, there are more and more electric vehicles on the road. In order to improve the driving safety of electric vehicles, it is necessary to equip them 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 located at the edge of the brake disc. High-pressure brake fluid pushes the brake pads inside the brake caliper to clamp the brake disc, thereby producing a braking effect.

[0003] To ensure the performance requirements of disc brakes during use, it is necessary to test the operating status of disc brakes. Traditional testing methods are very simple and can only be used to replace the next disc brake after testing the current one. This results in low testing efficiency and an inability to realistically simulate the actual driving and braking conditions of different vehicles, leading to insufficient simulation. Summary of the Invention

[0004] The technical problem that this invention aims to solve is that traditional testing methods are very simple and can only be used to replace the next disc brake after testing a single disc brake. This results in low testing efficiency and an inability to realistically simulate the actual driving and braking conditions of different vehicles, leading to insufficient simulation.

[0005] The technical solution adopted by this invention to solve its technical problem is: a rapid simulation testing device for the operating environment of disc brakes in electric vehicles, comprising a bottom-mounted testing box, a drive motor, and an air pump. The bottom-mounted testing box has an arc-shaped testing chamber with an upper opening. A vertical assembly plate controlled by the drive motor is movably mounted inside the arc-shaped testing chamber. An internal lateral mounting notch for mounting the disc brake disc is provided on the side wall of the vertical assembly plate. An embedded lateral fixing groove for mounting the disc brake caliper is provided on the inner side of the arc-shaped testing chamber. An electrically controlled telescopic transmission shaft that cooperates with the drive motor is mounted on the inner side of the arc-shaped testing chamber. A plurality of embedded temperature probes and optical recognition probes are mounted on the inner side of the arc-shaped testing chamber.

[0006] A circular embedded adjustment groove is provided on the inner side of the arc-shaped detection chamber, and an electrically controlled flow guide arm that cooperates with the air pump is installed inside the circular embedded adjustment groove.

[0007] A plurality of embedded limiting struts are installed on the inner side of the arc-shaped detection chamber, and an internal limiting through hole is opened inside the vertical assembly plate to cooperate with the embedded limiting struts.

[0008] Bottom support wheels and bottom drive wheels are movably installed on the bottom surface of the arc-shaped detection chamber.

[0009] The electrically controlled telescopic transmission shaft includes a main drive shaft sleeve axially fixed on the drive shaft of the drive motor, a telescopic shaft sleeve slidably sleeved on the main drive shaft sleeve, and an electrically controlled adjusting support rod fixed on the inner wall of the arc-shaped detection chamber. The extended end of the electrically controlled adjusting support rod is fixedly connected to the outer wall of the telescopic shaft sleeve through a lateral fixing frame.

[0010] The electrically controlled guide arm includes an inner exhaust pipe fixedly connected to the air outlet of the air pump, an inverted L-shaped lateral guide pipe sleeved on the outer opening of the inner exhaust pipe, an embedded adjustment motor fixed on the inner side of the circular embedded adjustment groove, an external driven gear axially sleeved on the outer side of the lateral guide pipe, an external drive gear axially fixed on the adjustment shaft of the embedded adjustment motor, and an oblique guide nozzle fixed on the outer air outlet of the lateral guide pipe.

[0011] The inner side of the internal lateral mounting notch is movably fitted with an internal mounting flange for fixing the disc brake disc. The disc brake disc is bolted to the internal mounting flange by fitting onto the threaded rod on the internal mounting flange through an internal mounting hole. A centrally located transmission shaft sleeve that mates with a telescopic shaft sleeve is provided at the center of the internal mounting flange.

[0012] An infrared positioning probe is fixedly mounted at the end of the embedded limiting support rod.

[0013] The bottom-mounted testing box is fixedly equipped with status indicator lights on its upper surface.

[0014] The inner side of the arc-shaped detection chamber is equipped with a built-in dust removal device located between the embedded temperature probe and the optical recognition probe.

[0015] The beneficial effects of this invention are:

[0016] (1) The present invention provides a rapid simulation test device for the use environment of disc brakes in electric vehicles. By using a disc adjustment method, the disc brake disc is guided into the arc-shaped test chamber and cooperates with the disc brake caliper inside the arc-shaped test chamber to complete the test operation inside. The continuous test method greatly improves the test efficiency.

[0017] (2) The split layout design can detect the effect of different specifications of disc brake components working together, thereby detecting the optimal combination and a wider detection range;

[0018] (3) By using the intracavitary detection method, the influence of the external environment on the detection results can be avoided, as well as the influence of the detection process on the external environment, thus ensuring detection accuracy;

[0019] (4) The disc brakes in the idle state can be replaced during the test without affecting the test process and reducing the cost of use in the later stage.

[0020] (5) The center of gravity of the entire device is lowered, which can improve the stability of the entire device;

[0021] (6) A circular embedded adjustment groove is provided on the inner side of the arc-shaped detection chamber. An electrically controlled guide arm that works with the air pump is installed inside the circular embedded adjustment groove. By changing the air direction, the air flow generated inside the chamber during driving can be simulated, thus simulating more environments.

[0022] (7) By adopting multiple detection methods such as temperature detection and optical detection, the operating status of disc brakes can be accurately detected. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The device shown is a rapid simulation testing device for the operating environment of disc brakes in electric vehicles. It includes a bottom-mounted testing box 1, a drive motor 2, and an air pump 3. The bottom-mounted testing box 1 has an arc-shaped testing chamber 4 with an opening at the top. A vertical mounting plate 5 controlled by the drive motor 2 is movably mounted inside the arc-shaped testing chamber 4. The side wall of the vertical mounting plate 5 has an internal lateral mounting notch 6 for mounting the disc brake disc. An embedded lateral fixing groove 7 for mounting the disc brake caliper is opened on the inner side of the arc-shaped testing chamber 4. An electrically controlled telescopic transmission shaft 8 that cooperates with the drive motor 2 is installed on the inner side of the arc-shaped testing chamber 4. Two embedded temperature probes 9 and an optical recognition probe 10 are installed on the inner side of the arc-shaped testing chamber 4.

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

[0033] Working principle: The disc brake disc is installed inside the internal lateral mounting notch 6. Then, the device is activated, and the vertical assembly plate 5 rotates the disc brake disc into the arc-shaped detection chamber 4. The optical recognition probe 10 at the opening position performs preliminary optical recognition recording on 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. Then, the electrically controlled telescopic drive shaft 8 is inserted into the center of the disc brake disc, driving the disc brake disc to rotate at high speed. When the speed reaches the set speed, the detection is activated, the disc brake caliper clamps the disc brake disc, and braking is initiated. Then, the embedded temperature probe 9 begins to detect the temperature at various positions of the disc brake disc. At the same time, the air pump 3 blows air onto the surface of the disc brake disc through the electrically controlled guide arm 12 to simulate the airflow changes during vehicle operation. After full braking, the disc brake caliper and the electrically controlled telescopic drive shaft 8 reset, the vertical assembly plate 5 drives the disc brake disc to rotate, and then the optical recognition probe 10 performs optical detection. The result is then compared with the preliminary optical recognition record to determine the changes on its surface.

[0034] To facilitate lateral positioning, a plurality of embedded positioning struts 13 are installed on the inner side of the arc-shaped detection chamber 4, and an internal positioning through hole 14 that cooperates with the embedded positioning struts 13 is provided inside the vertical assembly plate 5.

[0035] To support and drive the bottom of the opposing assembly plate 5, bottom support wheels 15 and bottom drive wheels 16 are movably installed on the bottom surface of the arc-shaped detection chamber 4.

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

[0037] To facilitate linkage control, the electrically controlled telescopic transmission shaft 8 includes a main drive shaft sleeve 81 axially fixed on the drive shaft of the drive motor 2, a telescopic shaft sleeve 82 slidably sleeved on the main drive shaft sleeve 81, and an electrically controlled adjusting support rod 83 fixed on the inner wall of the arc-shaped detection chamber 4. The extended end of the electrically controlled adjusting support rod 83 is fixedly connected to the outer wall of the telescopic shaft sleeve 82 through a lateral fixing frame 84.

[0038] The electrically controlled adjusting strut 83 extends, thereby driving the telescopic bushing 82 to slide and adjust along the outside of the main drive bushing 81.

[0039] To facilitate rotation adjustment and control of internal flow, the electrically controlled guide arm 12 includes an inner exhaust pipe 121 fixedly connected to the outlet of the air pump 3, a side 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 of the circular embedded adjustment groove 11, an external driven gear 124 axially sleeved on the outer side of the side guide pipe 122, an external drive gear 125 axially fixed on the adjustment shaft of the embedded adjustment motor 123, and an oblique guide nozzle 126 fixed on the outer outlet of the side 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 rotation of the lateral guide pipe 122, thereby adjusting the direction of air flow and adjusting the outlet position by changing the flow direction.

[0041] To facilitate fixed installation and removal, an internal mounting flange 17 for fixing the disc brake disc is movably mounted on the inner side of the internal lateral mounting notch 6. The disc brake disc is bolted to the internal mounting flange 17 by fitting onto the threaded rod 18 on the internal mounting flange 17 through the internal mounting hole. A centrally located drive shaft sleeve 19 that mates with the telescopic shaft sleeve 8 is provided at the center of the internal mounting flange 17.

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

[0043] The telescopic bushing 8 drives the disc brake disc to rotate by inserting it into the central drive bushing 19.

[0044] To facilitate precise positioning, an infrared positioning probe 20 is fixedly mounted at the end of the embedded limiting support rod 13.

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

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

[0047] When the test result is qualified, the status indicator light 21 will show green; when the test result is unqualified, the status indicator light 21 will show red, making it easier for people to judge the test result.

[0048] To facilitate 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 testing box 1. The built-in dust removal device 22 includes a dust collection box fixed in the installation slot, a metal filter box fixed on the top surface of the dust collection box, and a lateral exhaust pipe fixed on the outer surface of the dust collection box.

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

[0051] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
