Description

[0002] Currently, the brake master cylinder, booster and ESC (Electronic Stability Controller) of new energy vehicles have been combined into one part assembly, and the industry common name is One-Box. Due to the integration of more precise and small valve body structures inside One-Box, the requirements for the cleanliness and air permeability of the brake fluid are higher. In order to ensure the cleanliness of the brake fluid flowing from the brake fluid outlet of the brake fluid reservoir into the pedal simulator and the booster cylinder, a filter screen is generally placed between the bottom of the brake fluid outlet of the brake fluid reservoir and the inlet of the valve body to filter impurities in the brake fluid. However, the traditional filter screen cover is installed between the bottom of the oil outlet of the oil pot and the upper part of the liquid inlet of the valve body. The filter screen area is affected by the size of the oil inlet hole of the valve body, and impurities inside the oil pot are easily accumulated on the mesh surface, resulting in an increasingly smaller area for the brake fluid to pass through, blocking the liquid from entering the valve body, affecting the air permeability, and causing poor fluid compensation and reflux.

[0042] Next, refer to Figures 1 - 8 to describe the one-box hydraulic module assembly 100 according to an embodiment of the present utility model.

[0043] As Figures 1 - 3 shown, the one-box hydraulic module assembly 100 according to an embodiment of the present utility model includes: an oil pot 1, a valve body 2, and a filter assembly 3.

[0044] Specifically, as Figure 1 and Figure 2 shown, in combination with Figure 5 , the oil pot 1 has an oil outlet 11, and the oil outlet 11 can be provided on the bottom wall of the oil pot 1. The valve body 2 has an oil inlet 21, and the oil inlet 21 is communicated with the oil outlet 11. The brake fluid in the oil pot 1 can flow out through the oil outlet 11 and then flow into the valve body 2 through the oil inlet 21. The valve body 2 contains numerous machined channels, and the opening and closing of each major channel are controlled by solenoid valves to control the braking force of each wheel.

[0045] As Figures 3 - 5 shown, in combination with Figure 6As shown, the filter component 3 includes a framework 31 and a filter screen 32. The framework 31 is located inside the oil pot 1 and at least partially protrudes from the inner surface of the oil pot 1, that is, at least part of the framework 31 is located inside the inner surface of the oil pot 1. One end of the framework 31 in the length direction is connected to the oil pot 1, which can realize the fixation of the framework 31. The framework 31 has an oil passage 311 extending along the length direction of the framework 31. One end of the oil passage 311 is communicated with the oil outlet 11. An oil passing port 312 communicating the inner space of the oil pot 1 and the oil passage 311 is provided on the peripheral wall of the framework 31 protruding from the inner surface of the oil pot 1, that is, located inside the inner surface of the oil pot 1. All the oil passing ports 312 are located inside the oil pot 1. The brake fluid in the oil pot 1 can flow into the oil passage 311 through the oil passing port 312, then flow to the oil outlet 11, and then flow to the oil inlet 21 of the valve body 2 and enter the inside of the valve body 2.

[0046] In addition, the filter screen 32 is arranged in the oil passage 311 and blocks the oil passing port 312. The filter screen 32 can filter impurities in the brake fluid entering the valve body 2, ensure the cleanliness of the brake fluid entering the valve body 2, and ensure the reliability of the operation of the valve body 2. In this application, the framework 31 is located inside the oil pot 1, and the oil passing port 312 is arranged on the framework 31 inside the oil pot 1, so that the filter screen 32 is also located inside the oil pot 1. The area of the filter screen 32 is not limited by the sizes of the oil outlet 11 and the oil inlet 21, and the area of the oil passing port 312 can be increased, thereby increasing the area of the filter screen 32 opposite to the oil passing port 312, effectively increasing the area for the brake fluid to pass through, reducing the occurrence of the situation where the filter screen 32 is blocked, and ensuring the cleanliness and smoothness of the brake fluid.

[0047] According to the one-box hydraulic module assembly 100 of the embodiment of the present utility model, by making the framework 31 of the filter component 3 located inside the oil pot 1 and at least partially protruding from the inner surface of the oil pot 1, arranging an oil passage 311 communicated with the oil outlet 11 on the framework 31 and arranging an oil passing port 312 communicating the oil passage 311 and the inner space of the oil pot 1 on the framework 31 protruding from the inner surface of the oil pot 1, and arranging a filter screen 32 in the oil passage 311 to block the oil passing port 312, the area of the filter screen 32 is not limited by the sizes of the oil outlet 11 and the oil inlet 21. The area of the oil passing port 312 can be increased, thereby increasing the area of the filter screen 32 opposite to the oil passing port 312, effectively increasing the area for the brake fluid to pass through, reducing the occurrence of the situation where the filter screen 32 is blocked, and ensuring the cleanliness and smoothness of the brake fluid.

[0048] In some embodiments of the present utility model, as Figure 5 and Figure 6 shown, the oil passing port 312 is arranged at an interval from the surface of the oil pot 1 where the oil outlet 11 is located. For example, in Figure 3 and Figure 5In the illustrated example, the oil outlet 11 is provided on the bottom wall of the oil pot 1, and the oil passing port 312 is spaced from the inner bottom wall of the oil pot 1. Thus, when the impurities in the brake fluid are filtered by the filter screen 32, they will deposit at a position below the oil passing port 312, effectively preventing the impurities from accumulating on the filter screen 32 and causing blockage of the filter screen 32, resulting in poor flow of the brake fluid.

[0049] Furthermore, the distance between the oil passing port 312 and the surface of the oil pot 1 where the oil outlet 11 is located is 2 - 4 mm. For example, in Figure 3 and Figure 5 the illustrated example, the distance between the lower end of the oil passing port 312 and the inner bottom wall of the oil pot 1 is 2 - 4 mm. Among them, the distance between the oil passing port 312 and the surface of the oil pot 1 where the oil outlet 11 is located can be 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm, etc. Thus, it can not only ensure that the brake fluid in the oil pot 1 can smoothly flow out through the oil passing port 312, but also enable the impurities in the brake fluid to deposit at a position below the oil passing port 312 after being filtered by the filter screen 32, effectively preventing the impurities from accumulating on the filter screen 32 and causing blockage of the filter screen 32, resulting in poor flow of the brake fluid.

[0050] In some embodiments of the present utility model, as Figure 5 shown, the axis of the skeleton 31 is perpendicular to the bottom wall of the oil pot 1 where the oil outlet 11 is located. This facilitates the flow of the brake fluid.

[0051] In some embodiments of the present utility model, as Figure 5 shown, a part of the skeleton 31 is inserted into the oil outlet 11 and is in interference fit with the oil outlet 11. Thus, it is convenient for the assembly of the skeleton 31 and the oil pot 1, and can improve the reliability of the connection between the skeleton 31 and the oil pot 1. In addition, the interference fit between the skeleton 31 and the oil passing port 312 can also improve the sealing reliability between the skeleton 31 and the oil outlet 11.

[0052] Of course, a sealing ring can also be provided between the outer peripheral wall of the skeleton 31 and the inner peripheral wall of the oil outlet 11, thereby preventing the brake fluid from flowing directly to the valve body 2 through the gap between the skeleton 31 and the oil outlet 11 without being filtered by the filter screen 32, ensuring the cleanliness of the brake fluid entering the valve body 2 and ensuring the reliability of the operation of the valve body 2.

[0053] Furthermore, as Figure 6As shown, along the length direction of the framework 31, the framework 31 includes a first section 313 and a second section 314. The diameter of the second section 314 is smaller than that of the first section 313. The first section 313 is located inside the oil pot 1, and the oil passing port 312 is provided on the first section 313. The second section 314 is inserted into the oil outlet 11 and is in interference fit with the oil outlet 11. Thus, the diameter of the oil passage 311 inside the first section 313 can be increased, and it is convenient to set the oil passing port 312 on the first section 313. The width of the oil passing port 312 can be maximized in the circumferential direction of the framework 31, the oil passing area can be increased, and it is convenient to connect the second section 314 with the oil outlet 11.

[0054] In addition, the axial end face of the first section 313 facing the second section 314 can be in contact with the surface of the oil pot 1 having the oil outlet 11, effectively blocking the gap between the second section 314 and the oil outlet 11, ensuring that the oil liquid flows to the valve body 2 through the oil passing port 312 after being filtered by the filter screen 32, and preventing the filtered impurities from flowing to the valve body 2 through the gap between the second section 314 and the oil outlet 11.

[0055] It can be understood that the distance between the oil passing port 312 and the surface of the oil pot 1 provided with the oil outlet 11 can be the distance between the oil passing port 312 and the surface of the first section 313 facing the second section 314.

[0056] In some embodiments of the present utility model, as Figure 7 and Figure 8 shown, the oil passing ports 312 are multiple and spaced apart along the circumferential direction of the framework 31. The filter screen 32 is annular and blocks multiple oil passing ports 312 at the same time. Thus, the brake fluid in the oil pot 1 can enter the oil outlet 11 through multiple oil passing ports 312 and then enter the oil inlet 21 of the valve body 2. The total area of the oil passing ports 312 can be increased, and the brake fluid in the oil pot 1 can enter the oil passage 311 of the framework 31 from multiple directions in the circumferential direction of the framework 31, improving the smoothness of the flow of the brake fluid. In addition, the filter screen 32 is annular, which can simplify the structure of the filter screen 32 and facilitate the fixation of the filter screen 32 inside the framework 31, while ensuring the filtering effect of the filter screen 32 on the impurities in the oil passing ports 312.

[0057] For example, in the example shown in Figure 8 the oil passing ports 312 are three and spaced apart along the circumferential direction of the framework 31. The three oil passing ports 312 are evenly spaced along the circumferential direction of the framework 31, and the widths of the three oil passing ports 312 along the circumferential direction of the framework 31 are the same.

[0058] In some embodiments of the present utility model, as Figure 6 and Figure 7As shown, the oil passage port 312 extends along the length direction of the skeleton 31. Thereby, the oil passage area of the oil passage port 312 can be increased, so as to increase the filtering area of the filter screen 32, improve the passing efficiency of the brake fluid, and reduce the risk that the filter screen 32 is completely blocked.

[0059] Furthermore, along the length direction of the skeleton 31, the length of the oil passage port 312 is 30 - 40 mm. Thereby, it can not only ensure that the oil passage port 312 has a sufficiently large oil passage area, so as to increase the filtering area of the filter screen 32, improve the passing efficiency of the brake fluid, and reduce the risk that the filter screen 32 is completely blocked, but also avoid the skeleton 31 being too long, which is beneficial to improving the strength and saving the material cost.

[0060] For example, along the length direction of the skeleton 31, the length of the oil passage port 312 can be 32 mm, 34 mm, 36 mm or 38 mm, etc.

[0061] In some embodiments of the present utility model, the skeleton 31 is a PP (polypropylene) part. The skeleton 31 made of PP material can be integrally formed by an injection molding process, and has good heat resistance and corrosion resistance, which can improve the service life of the filtering component 3.

[0062] In some embodiments of the present utility model, the mesh size of the filter screen 32 is 150 - 200 meshes. In the related art, for a conventional filter screen to isolate impurities and ensure the cleanliness of the internal brake fluid, the mesh size of the filter screen is 80 - 100 meshes. However, in this application, since the area of the filter screen 32 becomes larger, the mesh size of the filter screen 32 can be set to 150 - 200 meshes, so that its ability to filter tiny impurities is greatly improved, and the cleanliness of the brake fluid entering the one - box line control braking system is ensured. At the same time, at this high mesh size, good fluidity can still be maintained (that is, more brake fluid passes through per unit time).

[0063] In some embodiments of the present utility model, the filtering component 3 is an integral part. Among them, the filtering component 3 can be formed into an integral part by an injection molding process. The filter screen 32 can be embedded in the inner surface of the skeleton 31 and integrated with the skeleton 31 at the joint when the skeleton 31 is injection - molded. Thereby, the assembly process between the filter screen 32 and the skeleton 31 can be saved, and the assembly efficiency can be improved.

[0064] In some embodiments of the present utility model, as Figure 2 and Figure 5 shown, the outer wall surface of the oil pot 1 has an annular boss 12. The annular boss 12 surrounds the oil outlet 11 and is inserted into the oil inlet 21. Thereby, the connection between the oil pot 1 and the valve body 2 can be realized, and at the same time, the communication between the oil outlet 11 and the oil inlet 21 can be realized, ensuring that the brake fluid in the oil pot 1 can flow smoothly into the valve body 2.

[0065] Further, as Figure 1 and Figure 2 shown, a sealing ring 4 is provided between the outer peripheral wall of the annular boss 12 and the inner peripheral wall of the oil inlet 21. This can ensure the seal between the annular boss 12 and the inner peripheral wall of the oil inlet 21, and prevent the brake fluid in the oil pot 1 from leaking through the gap between the annular boss 12 and the inner peripheral wall of the oil inlet 21.

[0066] It should be noted that when the brake fluid flows from the oil pot 1 into the valve body 2 or flows back from the valve body 2 to the oil pot 1, the brake fluid will always be filtered by the filter screen 32 during the flowing process.

[0067] In some embodiments of the present invention, as Figure 1 shown, the oil pot 1 includes an upper shell 14 and a lower shell 13. The upper shell 14 and the lower shell 13 are connected to jointly define a receiving cavity for receiving the brake fluid. A gasket may also be provided between the upper shell 14 and the lower shell 13. Among them, the oil outlet 11 is provided on the bottom wall of the lower shell 13, the skeleton 31 is connected to the lower shell 13, and an oil filling port is provided on the upper shell 14. An oil cap is connected to the oil filling port for blocking the oil filling port.

[0068] In some embodiments of the present invention, there are a plurality of spaced-apart oil outlets 11, a plurality of corresponding filter assemblies 3, and correspondingly, a plurality of corresponding oil inlets 21 on the valve body 2.

[0069] Next, a one-box electronic brake system according to an embodiment of the present invention will be described.

In addition, the one-box electronic brake system may further include an ESC (Electronic Stability Controller, electronic stability control system of the vehicle body), etc. The one-box electronic brake system is well known to those skilled in the art and will not be described in detail here.

[0071] According to the one-box wire-controlled braking system of the embodiments of the present utility model, by providing the above-mentioned one-box hydraulic module assembly 100, the skeleton 31 of the filter assembly 3 is located in the oil pot 1 and at least partially protrudes from the inner surface of the oil pot 1.

A filter screen 32 is provided in the oil passage 311 to block the oil passing port 312, so that the area of the filter screen 32 is not limited by the sizes of the oil outlet 11 and the oil inlet 21. By increasing the area of the oil passing port 312, the area of the filter screen 32 opposite to the oil passing port 312 can be increased, effectively increasing the area for the brake fluid to pass through, reducing the occurrence of the filter screen 32 being blocked, and ensuring the cleanliness and smoothness of the brake fluid.
