[0042] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0043] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0044] The brake fluid reservoir cap assembly 100 according to an embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

[0045] As Figures 1 to 4 shown, the brake fluid reservoir cap assembly 100 according to an embodiment of the present invention includes a body.

[0046] Specifically, the main body is provided with a liquid storage cavity 10, the main body is provided with a flow conversion channel 20, a first end of the flow conversion channel 20 is communicated with the liquid storage cavity 10, a second end of the flow conversion channel 20 is used for communicating with the outside, the main body is provided with a ventilation channel 411, a first end of the ventilation channel 411 is communicated with the liquid storage cavity 10, a second end of the ventilation channel 411 is used for communicating with the kettle body 200, and in the vertical direction, the first end of the ventilation channel 411 is higher than the first end of the flow conversion channel 20.

[0047] In other words, as Figures 1 to 4 shown, the brake fluid kettle lid assembly 100 according to an embodiment of the present invention is applied to a brake fluid kettle. The brake fluid kettle lid assembly 100 mainly includes a main body. Wherein, one end of the main body is provided with a connecting portion connected to the kettle body 200 of the brake fluid kettle, the main body is provided with a liquid storage cavity 10, and liquid can be stored through the liquid storage cavity 10; the main body is further provided with a flow conversion channel 20, a first end of the flow conversion channel 20 can be communicated with the liquid storage cavity 10, and a second end of the flow conversion channel 20 is kept communicated with the outside, so that gas or liquid from the outside can enter the liquid storage cavity 10 through the flow conversion channel 20, and liquid or gas in the liquid storage cavity 10 can also flow out through the flow conversion channel 20.

[0048] As Figures 1 to 4 shown, the main body is further provided with a ventilation channel 411. A first end of the ventilation channel 411 is used for communicating with the liquid storage cavity 10, and in the vertical direction, and the first end of the ventilation channel 411 is higher than the first end of the flow conversion channel 20. A second end of the ventilation channel 411 is used for communicating with the inside of the kettle body 200, so that the liquid storage cavity 10 can be communicated with the inside of the kettle body 200 through the ventilation channel 411. When the liquid level in the kettle body 200 changes, the gas in the liquid storage cavity 10 and the gas in the kettle body 200 can interact through the ventilation channel 411.

[0049] During use, the connecting portion of the main body is connected to the kettle body 200, a second end of the ventilation channel 411 is communicated with the inside of the kettle body 200, the kettle body 200 is filled with brake fluid, and a liquid outlet of the kettle body 200 is communicated with a brake pipeline of a braking system.

[0050] When the brake fluid reservoir cap assembly 100 works in a water-related environment, during braking of the braking system, the brake pipeline extracts brake fluid, the liquid level in the kettle body 200 drops, the first end of the air exchange channel 411 sucks air from the liquid storage cavity 10, causing a negative pressure in the liquid storage cavity 10. The external liquid is sucked into the flow conversion channel 20 from the second end of the flow conversion channel 20 and flows into the liquid storage cavity 10 from the first end of the liquid flow channel to balance the air pressure in the liquid storage cavity 10, that is, to supplement the volume after the brake fluid is extracted; it should be noted that when the braking system brakes, the liquid level entering the liquid storage cavity 10 is not higher than the first end of the air exchange channel 411 to prevent water from entering the kettle body 200 from the first end of the air exchange channel 411; that is, the volume between the first end of the air exchange channel 411 and the bottom of the liquid storage cavity 10 should be greater than the volume of the brake fluid extracted by the brake pipeline when the braking system brakes at the maximum power.

[0051] When the braking of the braking system is cancelled, the liquid level in the liquid storage cavity 10 rises, the first end of the air exchange channel 411 discharges air, a positive pressure is generated in the liquid storage cavity 10, and the liquid in the liquid storage cavity 10 can enter the flow conversion channel 20 from the first end of the flow conversion channel 20 under the action of the positive pressure and flow out from the second end of the flow conversion channel 20 to discharge the liquid in the liquid storage cavity 10 to the outside. It can ensure the air permeability of the air exchange channel 411 while preventing water from entering the brake fluid kettle, and can well meet the needs of the braking system for multiple brakings in water.

[0052] Thus, for the brake fluid reservoir cap assembly 100 according to the embodiment of the present invention, the liquid storage cavity 10 provided on the body can temporarily store the water flowing in from the flow conversion channel 20. Since the first end of the air exchange channel 411 is higher than the first end of the flow conversion channel 20, the liquid storage cavity 10 can absorb water from the flow conversion channel 20 as the braking system brakes and drain water through the flow conversion channel 20 as the braking of the braking system is cancelled. Therefore, it can meet the needs of the braking system for multiple brakings in water, ensure the reliability of the braking system, and further can well meet the needs of the vehicle for long-time driving in water, and improve the safety of the vehicle when driving in water.

[0053] In some embodiments of the present invention, in the vertical direction, the first end of the air exchange channel 411 is higher than the flow conversion channel 20.

[0054] In other words, when the brake fluid reservoir cap assembly 100 of this embodiment is in use, the horizontal height of the first end of the air exchange channel 411 is higher than the overall horizontal height of the flow conversion channel 20, which is convenient for discharging the liquid in the liquid storage cavity 10 and the flow conversion channel.

[0055] According to an embodiment of the present invention, the main body includes: a cover body 30 and a seal 40. The first end of the cover body 30 is used to connect to the kettle body 200. The seal 40 is disposed inside the cover body 30. A liquid storage cavity 10 is defined between the first side surface of the seal 40 and the inner surface of the cover body 30. A ventilation channel 411 is provided on the seal 40. A convex portion 41 is provided on the first side surface of the seal 40, and the ventilation channel 411 is provided on the convex portion 41.

[0056] That is to say, as Figure 1 shown, the main body mainly includes a cover body 30 and a seal 40. Among them, the first end of the cover body 30 is an open end. A connecting portion is provided at the first end of the cover body 30. Through the connecting portion, it can be connected to the kettle body 200. The connecting portion can be provided with a thread, so that it can be threadedly connected to the kettle body 200 through the connecting portion; the seal 40 is disposed inside the cover body 30. The first side surface of the seal 40 faces the second end of the cover body 30, and there is a gap between the first side surface of the seal 40 and the inner surface of the second end of the cover body 30, so that a liquid storage cavity 10 can be defined between the first side surface of the seal 40 and the inner surface of the cover body 30. The structure is simple and convenient for production and manufacturing.

[0057] As Figure 1 and Figure 4 shown, a convex portion 41 is provided on the first side of the seal 40. The first end of the ventilation channel 411 is disposed on the convex portion 41, so that the first end of the ventilation channel 411 can be at a higher position. The structure is simple and convenient for production and manufacturing.

[0058] In some examples of the present invention, the seal 40 is made of rubber material.

[0059] In some specific embodiments of the present invention, the convex portion 41 is formed as a ventilation column provided on the first side of the seal 40. The ventilation column extends away from the seal 40. The first end of the ventilation channel 411 is disposed at the end of the convex portion 41 away from the seal 40. The second end of the ventilation channel 411 is communicated with the kettle body 200.

[0060] Specifically, as Figure 1 and Figure 4 shown, the seal 40 is formed as an annular sheet body. A ventilation column is provided on the inner ring of the seal 40. The first end of the ventilation column is connected to the inner ring contour of the seal 40. The second end of the ventilation column is located in the liquid storage cavity 10, and the ventilation column can extend away from the seal 40. In this embodiment, the ventilation column can be used as the convex portion 41. The first end of the ventilation channel 411 can be disposed at the second end of the ventilation column. The second end of the ventilation channel 411 can extend along the axis of the ventilation column to the first end of the ventilation column, so that the second end of the ventilation channel 411 can be communicated with the kettle body 200.

[0061] In this embodiment, the first end of the ventilation passage 411 is provided at the end of the protrusion 41 away from the seal 40, which can make the first end of the ventilation passage 411 be at the highest point of the protrusion 41, maximize the utilization of the protrusion 41, increase the height of the first end of the ventilation passage 411, and thus effectively avoid the over - large volume of the brake fluid reservoir cap assembly 100.

[0062] In some examples of the present invention, the ventilation passage 411 is formed as a through - hole provided in the seal 40.

[0063] According to an embodiment of the present invention, a ventilation portion 412 is provided at the end of the protrusion 41 away from the seal 40. The ventilation portion 412 is located at the first end of the ventilation passage 411, and a plurality of ventilation portions 412 are movable so that the ventilation passage 411 can be switched between an open state and a closed state.

[0064] That is to say, as Figure 4 shown, four ventilation portions 412 can be provided at the second end of the ventilation column. The ventilation portion 412 can be formed as a valve film structure. Through the four ventilation portions 412, the first end of the ventilation passage 411 can be blocked, so that the ventilation passage 411 can be in a closed state, thereby avoiding the water splashed in the liquid storage cavity 10 from entering the ventilation passage 411 when there is no ventilation, and further effectively preventing the brake fluid in the pot body 200 from being polluted by water.

[0065] It should be noted that the ventilation portion 412 has a certain elasticity, so that the ventilation portion 412 can be movable under the influence of air pressure, and thus the ventilation passage 411 can be switched between an open state and a closed state. When positive pressure is generated in the pot body 200, a plurality of ventilation portions 412 open outwards. At this time, the ventilation passage 411 is in an open state; when negative pressure is generated in the pot body 200, a plurality of ventilation portions 412 open inwards. At this time, the ventilation passage 411 is also in an open state; when the air pressure in the pot body 200 is balanced with the air pressure in the liquid storage cavity 10, the adjacent ventilation portions 412 rebound to the initial state. At this time, the ventilation passage 411 is in a closed state.

[0066] Furthermore, the ventilation column is made of rubber material, the second end of the ventilation column is a sealed end, and a cross - shaped cut is provided at the second end of the ventilation column, so that a part of the second end of the ventilation column forms the ventilation portion 412.

[0067] In some specific embodiments of the present invention, a limiting portion 31 is provided between the end of the protrusion 41 away from the seal 40 and the inner surface of the liquid storage cavity 10. The limiting portion 31 is provided on the protrusion 41 and / or the cover body 30. The limiting portion 31 is used to limit the distance between the end of the protrusion 41 away from the seal 40 and the inner surface of the liquid storage cavity 10, so that there is a gap between the end of the protrusion 41 away from the seal 40 and the inner surface of the liquid storage cavity 10.

[0068] Specifically, as Figures 1 to 3 shown, there is a gap between the end of the protrusion 41 away from the seal 40 and the inner surface of the second end of the cover 30. The set gap can ensure that the ventilation channel 411 communicates with the liquid storage chamber 10. When the gap is large, it can prevent the protrusion 41 from contacting the inner wall of the liquid storage chamber 10 during movement, thereby preventing the ventilation part 412 from contacting the inner surface of the liquid storage chamber 10, ensuring the ventilation of the ventilation channel 411, and preventing the gas in the kettle body 200 from being discharged from other positions with poor airtightness or the kettle body 200 from deforming. When the gap is small, a limiting part 31 can be provided between the end of the protrusion 41 away from the seal 40 and the inner surface of the second end of the cover 30. The specific positions of the limiting part 31 include but are not limited to the following situations:

[0069] Situation 1: The limiting part 31 can be provided on the cover 30;

[0070] Situation 2: The limiting part 31 can be provided on the protrusion 41;

[0071] Situation 3: Limiting parts 31 are respectively provided on the cover 30 and the protrusion 41.

[0072] The limiting part 31 can limit the movement position of the protrusion 41, thereby preventing the inner surface of the liquid storage chamber 10 from blocking the first end of the ventilation channel 411, ensuring the ventilation of the ventilation channel 411, and further preventing the water level in the water storage chamber from rising above the first end of the ventilation channel 411 and entering the kettle body 200 after multiple brakings of the braking system.

[0073] In this embodiment, the ventilation of the ventilation channel 411 can be ensured through the limiting part 31, so that the water in the liquid storage chamber 10 will not gradually increase under multiple brakings of the braking system, and the requirement of the braking system for multiple brakings with water can be further improved.

[0074] According to an embodiment of the present invention, the limiting part 31 is formed as a protrusion provided on the inner surface of the liquid storage chamber 10 facing the first end of the ventilation channel 411.

[0075] That is to say, a limiting part 31 is provided at the position corresponding to the protrusion 41 on the inner surface of the liquid storage chamber 10 facing the first end of the ventilation channel 411. The limiting part 31 can be formed as a protrusion. For example, the limiting part 31 can be formed as a rib structure, which has a simple structure and is convenient for integrally injection molding with the cover 30, facilitating production and manufacturing.

[0076] According to an embodiment of the present invention, the limiting part 31 extends along the circumferential direction of the ventilation channel 411, and the limiting part 31 is provided with at least one ventilation groove 311 penetrating radially along the ventilation channel 411.

[0077] Specifically, as Figure 2and Figure 3 As shown, the limiting portion can be formed as an annular shape extending along the circumferential direction of the air exchange channel 411, and the limiting portion 31 is provided with a plurality of ventilation grooves 311 penetrating therethrough in the radial direction thereof. The plurality of ventilation grooves 311 can be spaced apart along the circumferential direction of the air exchange channel 411. In this embodiment, the limiting portion 31 can limit the protruding portion 41 and the ventilation portion 412 in the circumferential direction of the air exchange channel 411, which can prevent the inner surface of the liquid storage cavity 10 from blocking the air exchange channel 411, so that the air exchange channel 411 can communicate with the liquid storage cavity 10 through the ventilation grooves 311, thereby effectively ensuring the air permeability of the air exchange channel 411.

[0078] In some specific embodiments of the present invention, a support portion 32 extending along the axial direction thereof is provided in the cover body 30. A flow conversion groove 321 is provided on one side of the support portion 32 close to the seal member 40. At least a part of the flow conversion channel 20 is defined by the first side of the seal member 40 and the wall surface of the flow conversion groove 321.

[0079] That is to say, as Figures 1 to 3 shown, a support portion 32 extending along the axial direction thereof is provided in the cover body 30. The installation position of the seal member 40 can be limited by the support portion 32. The first side of the seal member 40 is attached to the support portion 32. A flow conversion groove 321 is provided on one side of the support portion 32 close to the seal member 40. The first end of the flow conversion groove 321 communicates with the liquid storage cavity 10, and the second end of the flow conversion groove 321 communicates with the outside. Thus, the flow conversion channel 20 can be defined by the inner surface of the flow conversion groove 321 and the first side of the seal member 40.

[0080] In some other examples of the present invention, a first connection groove 322 is provided on the inner surface of the liquid storage cavity 10. The first end of the flow conversion channel 20 is provided in the first connection groove 322. The smoothness of the flow conversion channel 20 can be ensured by the first connection groove 322, and the seal member 40 can be prevented from blocking the flow conversion channel 20.

[0081] In an example of the present invention, a second connection groove 34 is provided on the inner side of the cover body 30. The first end of the second connection groove 34 communicates with the second end of the flow conversion groove 321, and the second end of the second connection groove 34 extends to the first end of the cover body 30. Thus, a flow channel communicating with the outside can be formed between the cover body 30 and the kettle body 200 through the second connection groove 34, and further, the flow conversion channel 20 can be ensured to communicate with the outside.

[0082] In some specific embodiments of the present invention, the flow conversion channel 20 is formed as a through hole provided on one side of the cover body 30. The first end of the through hole communicates with the liquid storage cavity 10, and the second end of the through hole communicates with the outside.

[0083] According to an embodiment of the present invention, the support portion 32 is formed as a boss extending along the circumferential direction of the cover body 30. At least one sealing portion 42 extending along the circumferential direction thereof is provided on the first side of the sealing member 40, and the sealing portion 42 is adapted to abut against the support portion 32.

[0084] Specifically, as Figures 1 to 3 shown, two sealing portions 42 extending along the circumferential direction thereof are provided on the first side of the sealing member 40. The sealing portion 42 can be formed as a rib structure. The two sealing portions 42 are spaced apart along the radial direction of the sealing member 40. The support portion 32 is formed as an annular boss adapted to the sealing portion 42. By abutting the sealing portion 42 against the support portion 32, the airtightness between the sealing member 40 and the support portion 32 can be improved, thereby avoiding gas or water from entering the liquid storage cavity 10 from positions other than the commutation channel 20.

[0085] When assembling the brake fluid reservoir assembly, the cover body 30 is threadedly connected to the reservoir body 200, and the reservoir body 200 abuts against the second side of the sealing member 40, so that the first side of the sealing member 40 abuts against the support portion 32, and the sealing member 40 is deformed under pressure, thereby realizing the sealing with each component.

[0086] In some specific embodiments of the present invention, at least one buffer plate 33 is provided in the liquid storage cavity 10. The buffer plate 33 is provided on the cover body 30 or the sealing member 40, and the buffer plate 33 is located on the outer periphery of the air exchange channel 411.

[0087] That is to say, a buffer plate 33 extending along the axial direction thereof can be provided on the outer periphery of the air exchange channel 411. The buffer plate 33 can buffer the water flow in the liquid storage cavity 10, avoid the generation of rapids of the water in the liquid storage cavity 10, and thus effectively avoid the water in the liquid storage cavity 10 from entering the reservoir body 200 from the first end of the air exchange channel 411. In this embodiment, the buffer plate 33 can be provided on the cover body 30 or the sealing member 40, and its specific setting position can be determined according to the actual situation, which will not be elaborated in this embodiment.

[0088] According to an embodiment of the present invention, the buffer plate 33 is formed as an annular plate extending along the axial direction of the cover body 30. The convex portion 41 is located inside the buffer plate 33. The buffer plate 33 is provided with at least one communication groove 331 penetrating along the radial direction of the cover body 30. The buffer plate 33 is used to divide the liquid storage cavity 10 into different parts, and the communication groove 331 is used for the liquid to flow in different parts of the liquid storage cavity 10.

[0089] In this embodiment, the buffer plate 33 is connected to the cover body 30, and the convex portion 41 is located inside the buffer plate 33. The buffer plate 33 can buffer the water flow on the outer periphery of the ventilation channel 411, effectively preventing water from entering the ventilation channel 411, enabling the water inhaled by the flow conversion channel 20 to accumulate in the liquid storage cavity 10. Moreover, the inner space and the outer space of the annular plate can be communicated through the communication groove 331, making full use of the gas in the liquid storage cavity 10 and enabling the vehicle's floating function to be achieved with a smaller body size.

[0090] As Figures 1 to 3 shown, in some specific embodiments of the present invention, the communication groove 331 axially penetrates the buffer plate 33 in the cover body 30, thereby preventing the water in the liquid storage cavity 10 from submerging the communication groove 331 and ensuring the ventilation of the ventilation channel 411.

[0091] According to an embodiment of the present invention, there are multiple buffer plates 33. The multiple buffer plates 33 are spaced apart radially in the cover body 30, and the communication grooves 331 on adjacent buffer plates 33 are staggered circumferentially in the cover body 30.

[0092] Specifically, as Figure 2 shown, the inner side surface of the cover body 30 is provided with multiple buffer plates 33. The multiple buffer plates 33 are spaced apart radially in the cover body 30. Each buffer plate 33 is provided with a communication groove 331. The communication grooves 331 on adjacent buffer plates 33 are staggered circumferentially in the cover body 30. For example, the design angle difference between the communication grooves 331 on adjacent buffer plates 33 is 180 degrees.

[0093] In this embodiment, through the cooperation of the multiple buffer plates 33 and the communication grooves 331, multi-stage buffering of the water flow can be achieved, effectively preventing the water in the water storage cavity from entering the ventilation channel 411 and improving the reliability of the braking system when braking in water.

[0094] In some specific embodiments of the present invention, the communication groove 331 of the buffer plate 33 close to the flow conversion channel 20 is staggered circumferentially in the cover body 30 from the first end of the flow conversion channel 20.

[0095] That is to say, as Figure 2 shown, when the buffer plate 33 is an annular plate, the communication groove 331 provided on the outermost buffer plate 33 can be staggered from the first end of the flow conversion channel 20. For example, the two can be staggered circumferentially in the cover body 30, thereby preventing the water flow entering from the flow conversion channel 20 from shooting into the ventilation channel 411 and further improving the reliability of the braking system when braking in water.

[0096] In summary, for the brake fluid reservoir cap assembly 100 according to the embodiment of the present invention, the liquid storage cavity 10 provided on the body can temporarily store the water flowing in from the flow conversion channel 20. Since the first end of the air exchange channel 411 is higher than the first end of the flow conversion channel 20, the liquid storage cavity 10 can absorb water from the flow conversion channel 20 during the braking of the braking system and drain water from the flow conversion channel 20 when the braking of the braking system is cancelled. Thus, it can meet the needs of the braking system for multiple brakings in water, ensure the reliability of the braking system, and further well meet the needs of the vehicle for long-time driving in water, and improve the safety of the vehicle when driving in water.

[0097] As Figure 5 and Figure 6 shown, the embodiment of the present invention also provides a brake fluid reservoir assembly, including the brake fluid reservoir cap assembly 100 and the reservoir body 200 described in any of the above embodiments. Since the brake fluid reservoir cap assembly 100 according to the embodiment of the present invention can solve the problem of poor reliability of the existing braking system, the brake fluid reservoir assembly according to the embodiment of the present invention also has the above advantages, that is, it can meet the needs of the braking system for multiple brakings in water, ensure the reliability of the braking system, and further well meet the needs of the vehicle for long-time driving in water, and improve the safety of the vehicle when driving in water.

[0098] The embodiment of the present invention also provides a braking system, including the brake fluid reservoir assembly described in the above embodiment. Since the brake fluid reservoir assembly according to the embodiment of the present invention can solve the problem of poor reliability of the existing braking system, the braking system according to the embodiment of the present invention also has the above advantages, which will not be elaborated in this embodiment.

[0099] The embodiment of the present invention also provides a vehicle, including the brake fluid reservoir assembly or the braking system described in the above embodiment. Since both the brake fluid reservoir assembly and the braking system according to the embodiment of the present invention can solve the problem of poor reliability of the existing braking system, the vehicle according to the embodiment of the present invention also has the above advantages, which will not be elaborated in this embodiment.
