Technical Field

[0001] The present invention relates to the technical field of electric vehicle disc brake detection, in particular to an environmental simulation device applied to electric vehicle disc brake detection. Background Art

[0002] With the development of technology, more and more electric vehicles are on the market. In order to improve the driving safety of electric vehicles, it is necessary to install disc brakes on electric vehicles to enhance the braking performance of electric vehicles. Disc brakes are a braking system composed 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.

[0003] In order to ensure the performance reliability of disc brakes during use, it is necessary to test the operating status of disc brakes after they are produced. However, the traditional testing method is very simple, and can only remove and replace the next disc brake after a single disc brake is tested. The testing efficiency is low, and it cannot truly simulate the actual state of different vehicles under driving and braking, resulting in insufficient simulation. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the traditional detection method is very simple, and can only remove and replace the next disc brake after the single disc brake is detected. The detection efficiency is low, and it is impossible to truly simulate the actual state of different vehicles under driving and braking, resulting in insufficient simulation.

[0010] A distance sensor module, a temperature sensor module, a humidity sensor module and an optical recognition module are fixedly mounted on the inner side of the flip air deflector.

[0011] The front of the main frame is fixedly equipped with an arc-shaped bottom-mounted liquid collecting cover below the longitudinal mounting plate, and both sides of the arc-shaped bottom-mounted liquid collecting cover are slidably equipped with expanded lateral liquid blocking covers.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] 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.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4 An environmental simulation device for electric vehicle disc brake detection is shown, comprising a main frame 1, a longitudinal mounting plate 2 is fixedly mounted on the side wall of the main frame 1, an electric control simulation seat 3 for mounting a brake disc is movably mounted on the side wall of the longitudinal mounting plate 2, two adjustment mounting guide rails 4 are fixedly mounted on the outer arc surface of the longitudinal mounting plate 2, and a first adjustment mounting seat 5 and a second adjustment mounting seat 6 for mounting an electric vehicle disc brake are movably mounted on the outer side of the adjustment mounting guide rail 4.

[0030] Working principle: people fix the brake disc on the front of the electronically controlled simulation seat 3, and then control the second adjustment assembly seat 6 on the adjustment mounting guide rail 4 at the 2 o'clock direction to move toward the brake disc position, and then flip outward to the outside of the brake disc, and then the first adjustment assembly seat 5 at the 11 o'clock direction moves toward the brake disc position, and then flips outward to the outside of the brake disc, forming a mutually coordinated simulation detection mechanism.

[0031] To facilitate loading and unloading, the electric control simulation seat 3 includes a driving motor 31 fixed to the back of the longitudinal mounting plate 2, a front assembly seat 32 arranged on the front of the longitudinal mounting plate 2, and 6 assembly bolts fixed to the front of the front assembly seat 32.

[0032] In order to adjust the gap between the brake pad and the brake disc, the adjusting mounting rail 4 includes a lateral mounting plate 41 fixed on the outer side of the longitudinal mounting disc 2, an adjusting rail 42 fixed on the lateral mounting plate 41 and an electric control screw rod 43 installed inside the adjusting rail 42.

[0033] The electric control screw rod 43 can respectively control the first adjustment assembly seat 5 and the second adjustment assembly seat 6 at different positions by rotating.

[0034] When it is necessary to combine with the brake disc, the detection begins, and when replacement is needed, the gap between the brake pad and the brake disc is widened, and people can replace it while maintaining a safe distance.

[0035] In order to cooperate with the flipping of the angle of the electric vehicle disc brake assembly seat 52, the first adjustment assembly seat 5 includes a first internal thread translation seat 51 threadedly sleeved on the electric control screw rod 43, an electric vehicle disc brake assembly seat 52 movably mounted on the first internal thread translation seat 51 and a lateral hydraulic support rod 53 for adjusting the electric control vehicle disc brake assembly seat 52.

[0036] After the disc brake pad is installed on the electric vehicle disc brake assembly seat 52, the lateral hydraulic support rod 53 is stretched by pressurization to control the electric vehicle disc brake assembly seat 52 to flip over to the outside of the brake disc, so as to normally simulate a disc brake installed on the frame.

[0037] In order to cooperate with the height and flip adjustment, and then adjust the air flow and humidity on the surface of the brake disc, the second adjustment assembly seat 6 includes a second internal threaded translation seat 61 threadedly sleeved on the electric control screw 43, a flip air deflector 62 movably mounted on the second internal threaded translation seat 61, a lateral support rod 63 for controlling the flip air deflector 62, an external air guide tube 64 and an external liquid guide tube 65 fixed on the outer side of the flip air deflector 62.

[0038] The second internal thread translation seat 61 is controlled to slide along the adjustment guide rail 42 by rotating the electric control screw rod 43, and then the lateral support rod 63 is extended and retracted to control the flipping of the air deflector 62 for flipping control.

[0039] In order to detect the temperature, humidity, dust thickness and surface wear of the brake pad surface, a distance sensor module 7, a temperature sensor module 8, a humidity sensor module 9 and an optical recognition module 10 are fixedly mounted on the inner side of the flip deflector 62.

[0040] The distance sensor module 7 cooperates with the optical recognition module 10 to detect the accumulation thickness of dust on the surface of the brake disc and the degree of wear on its surface. The degree of wear of the brake pad is calculated by the thickness of a single wear. At the same time, the optical recognition module 10 can also be directed toward the brake pad position, so that the thickness of the brake pad can be detected more directly.

[0041] The temperature sensor module 8 and the humidity sensor module 9 monitor the temperature and humidity of the brake disc surface respectively, so as to achieve the purpose of simulating different climate environments.

[0042] In order to improve the collection effect of dust and detection liquid, an arc-shaped bottom liquid collecting cover 11 is fixedly installed on the front of the main frame 1 below the longitudinal mounting plate 2, and extended side liquid blocking covers 12 are slidably installed on both sides of the arc-shaped bottom liquid collecting cover 11.

[0043] Guide grooves with outer openings are provided on the inner walls on both sides of the arc-shaped bottom liquid collecting cover 11, and the expanded lateral liquid blocking cover 12 is slidably inserted into the guide grooves. An electric regulating wheel is installed at the outer opening position of the guide groove, and drives it to slide by rolling friction with the outer arc surface of the expanded lateral liquid blocking cover 12.

[0044] In order to cooperate with the movable assembly, the side wall of the first internal thread translation seat 51 has a lateral assembly axis 13 protruding outward, and the electric vehicle disc brake assembly seat 52 is movably assembled with the first internal thread translation seat 51 by being sleeved on the lateral assembly axis 13. The surface of the first internal thread translation seat 51 is located outside the lateral assembly axis 13 and an embedded annular electromagnet 14 is fixedly installed.

[0045] During detection, the lateral stability of the electric vehicle disc brake assembly seat 52 can be enhanced by activating the embedded annular electromagnet 14 .

[0046] In order to increase the squeezing force on the outside and enhance the stability of the entire electric vehicle disc brake assembly seat 52 , a locking bolt 15 is threadedly mounted on the outer end of the lateral assembly shaft 13 , and an squeezing spring 16 is sleeved on the inner side of the locking bolt 15 on the lateral assembly shaft 13 .

[0047] In order to facilitate assembly and control, an external sinking groove for installing the lateral hydraulic support rod 53 is opened on the side wall of the first internal thread translation seat 51, and an external control rod matching the lateral hydraulic support rod 53 is provided on the side wall of the electric vehicle disc brake assembly seat 52.

[0048] One side of the lateral hydraulic support rod 53 is movably installed in the external sinking groove through an axis, and the other side is movably assembled with the side wall of the electric vehicle disc brake assembly seat 52 by sleeves on the external control rod through an assembly ring at the extended end.

[0049] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description.
