[0032] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0033] Reference below Figure 1-Figure 4 An oil pot cover assembly 10 according to an embodiment of the present application is described, and the oil pot cover assembly 10 includes a base 11 and an oil baffle seat 12, a first accommodating cavity 111 is formed on the base 11, one end of the oil baffle seat 12 is received in the first accommodating cavity 111 and is connected to the inner wall of the base 11, and the other end of the oil baffle seat 12 is connected to the oil storage pot 20, and a second accommodating cavity 121 is formed in the oil baffle seat 12, wherein a throttling hole 13 suitable for connecting the interior of the oil storage pot 20 with the second accommodating cavity 121 is formed at one end of the oil baffle seat 12 facing the oil storage pot 20, and the throttling hole 13 includes a first hole section 131 and a second hole section 132, the first hole section 131 is arranged close to the oil pot, and the second hole section 132 is arranged close to the second accommodating cavity 121, and the inner diameter of the first hole section 131 is smaller than the inner diameter of the second hole section 132.

[0034] At present, the integrated brake control modules installed in vehicles are all equipped with a brake fluid reservoir. Due to the spatial angle of the front cabin layout and the filling space of the vehicle, the filling port of the reservoir cannot be completely horizontal. Under normal operating conditions, the oil reservoir cover must be able to ensure ventilation to avoid the formation of secondary pressure inside and hinder the push rod of the integrated brake control module from returning. Under downhill conditions, the braking conditions are superimposed, the oil reservoir and the brake fluid tilt forward, and air can easily enter the oil reservoir from the oil reservoir cover and then into the master cylinder of the integrated brake control module. The brake fluid will seep out from the filling port of the oil reservoir, increasing the risk of brake fluid seepage and air entering the brake system.

[0035] like Figure 1-Figure 3 As shown, specifically, the oil pot cover assembly 10 includes a base 11 and an oil baffle seat 12, a first accommodating cavity 111 is formed on the base 11, and the inner diameter of the base 11 is larger than the maximum outer diameter of the oil baffle seat 12, one end of the oil baffle seat 12 can be accommodated in the first accommodating cavity 111, and one end of the oil baffle seat 12 can be connected to the inner wall of the base 11, optionally, the oil baffle seat 12 and the inner wall of the base 11 can form a detachable connection by snapping or plugging, the other end of the oil baffle seat 12 can be connected to the oil storage pot 20, optionally, the oil baffle seat 12 and the oil storage pot 20 can be connected by a seal 15 or interference fit.

[0036] Furthermore, a second accommodating chamber 121 is formed inside the oil baffle seat 12, and a throttling hole 13 is formed at one end of the oil baffle seat 12 facing the oil reservoir 20, wherein the throttling hole 13 can connect the interior of the oil reservoir 20 with the second accommodating chamber 121, wherein the throttling hole 13 may include a first hole section 131 and a second hole section 132, the first hole section 131 is arranged close to the oil reservoir, and the second hole section 132 is arranged close to the second accommodating chamber 121, and the inner diameter of the first hole section 131 is smaller than the inner diameter of the second hole section 132. Due to the influence of the surface tension of the brake fluid, the liquid surface always tends to shrink, so there will be resistance to forming a concave liquid surface, and the smaller the scale, the greater the resistance. Therefore, the brake fluid at the first hole section 131 will not flow out within a certain period of time, and the oil reservoir cover assembly 10 will not be affected at any angle, which is more conducive to the arrangement of the filling port, so that the brake fluid does not leak out and the air cannot enter the brake system, thereby improving the safety of the brake system.

[0037] In short, the oil pot cover assembly 10 of the present application has a base 11 and an oil baffle seat 12, and a throttle hole 13 is formed on the oil baffle seat 12 to connect the interior of the oil storage pot 20 with the second accommodating chamber 121. The throttle hole 13 can be constructed as a step hole, and the throttle hole 13 has a first hole section 131 and a second hole section 132. The inner diameter of the first hole section 131 is smaller than the inner diameter of the second hole section 132. Short-term flow resistance and sealing are achieved through the molecular tension of the brake fluid, ensuring that the brake fluid does not leak out and air cannot enter the brake system. Under normal working conditions, the air permeability can be guaranteed, greatly improving the safety of the brake system.

[0038] like Figure 3 As shown, in some embodiments of the present application, the inner diameter of the first hole section 131 is D1, and the inner diameter D1 can meet the following conditions: 0.6mm≤D1≤1mm. In a specific embodiment, the inner diameter of the first hole section 131 is preferably 0.8mm, and the inner diameter of the second hole section 132 is D2, and the inner diameter D2 can meet the following conditions: 1.3mm≤D2≤1.7mm. In a specific embodiment, the inner diameter of the second hole section 132 is preferably 1.5mm. By comparing the inner diameters of the first hole section 131 and the second hole section 132, it can be ensured that the throttle hole 13 can be constructed as a step hole, and short-term flow blocking and sealing can be achieved through the molecular tension of the brake fluid, ensuring that the brake fluid does not leak out and air cannot enter the brake system.

[0039] like Figure 3 As shown, in some embodiments of the present application, the throttle hole 13 can be constructed in plurality, and the plurality of throttle holes 13 can be arranged at intervals in the circumferential direction of the oil block seat 12. By providing a plurality of throttle holes 13, the oil tank cover assembly 10 can be ensured to be breathable under normal working conditions, so as to prevent the formation of secondary pressure inside the oil tank 20 and hinder the return of the push rod of the integrated brake control module.

[0040] like Figure 2 As shown, in some embodiments of the present application, the oil block seat 12 has a first end 122 and a second end 123, the first end 122 can be accommodated in the first accommodating cavity 111, and the first end 122 can be connected to the inner wall of the base 11, optionally, the first end 122 and the inner wall of the base 11 can form a detachable connection by snapping and plugging, the second end 123 is spaced apart from the first end 122 to form a second accommodating cavity 121, and a throttling hole 13 can be formed on the second end 123, wherein the outer diameter of the first end 122 is larger than the outer diameter of the second end 123, thereby ensuring that the second end 123 can be connected to the oil storage pot 20 to achieve sealing.

[0041] like Figure 2 As shown, in some embodiments of the present application, the oil pot cover assembly 10 also includes an inner seat 14, which is arranged in the second accommodating cavity 121, and the two ends of the inner seat 14 in the axial direction are respectively fitted with the second end 123 and the base 11, wherein a first groove body 141 and a second groove body 142 are formed on the inner seat 14, and the first groove body 141 and the second groove body 142 are respectively recessed toward the inner seat 14, and further, the first groove body 141 is communicated with the first throttle hole 13, and the second groove body 142 is communicated with the first groove body 141. It should be noted that the first groove body 141 A connecting hole 143 connected with the second accommodating chamber 121 is respectively formed on the second slot body 142. When the brake fluid flows into the first slot body 141 through the throttle hole 13, it is necessary to first fill the first slot body 141 and then flow into the second accommodating chamber 121 through the connecting hole 143 of the first slot body 141. The brake fluid in the second accommodating chamber 121 flows into the second slot body 142 through the connecting hole 143 of the second slot body 142 until the second slot body 142 is filled and then continues to flow to the outside, thereby slowing down the leakage of the brake fluid and greatly improving the safety of the braking system.

[0042] like Figure 2 As shown, in some embodiments of the present application, a protrusion 124 is formed on the first end portion 122, and the protrusion 124 can be arranged on the outer peripheral wall of the first end portion 122 and extend toward the base 11. A groove portion 112 is formed on the inner wall of the base 11, and the groove portion 112 can be recessed toward the inner wall of the base 11, and the groove portion 112 can cooperate with the protrusion 124. By snap-fitting the protrusion 124 with the groove portion 112, the protrusion 124 is accommodated in the groove portion 112, and the outer surface of the protrusion 124 stops against the inner surface of the groove portion 112 to limit the movement of the protrusion 124, so that the first end portion 122 is installed on the base 11.

[0043] like Figure 2As shown, in some embodiments of the present application, a seal 15 is provided on the outer peripheral wall of the oil baffle seat 12, and the seal 15 can be arranged around the outer peripheral wall of the oil baffle seat 12. Optionally, the seal 15 can be arranged on the outer peripheral wall of the oil baffle seat 12 by interference fit, and the seal 15 can be located between the first end 122 and the second end 123 to ensure that when the oil pot cover assembly 10 is matched with the oil storage pot 20, the seal 15 can be located between the outer peripheral wall of the oil baffle seat 12 and the liquid outlet of the oil storage pot 20, thereby achieving a sealing effect and preventing the outflow of brake fluid.
