[0001] This application relates to the field of automotive technology, and more particularly to a brake fluid reservoir, a braking system, and a vehicle. Background Technology

[0002] The brake fluid reservoir currently used in automobiles primarily functions as a container for storing brake fluid. Brake fluid is poured into the reservoir from the outlet and temporarily stored. When the braking system requires brake fluid, the reservoir's outlet is opened, allowing the fluid to flow to where it is needed. However, in some technologies, the fluid inside the reservoir vibrates violently with vehicle movement, generating noise and potentially shortening the reservoir's lifespan. Utility Model Content

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0058] The brake fluid reservoir currently used in automobiles primarily functions as a container for storing brake fluid. Brake fluid is poured into the reservoir from the outlet and temporarily stored. When the braking system requires brake fluid, the reservoir's outlet is opened, allowing the fluid to flow to where it is needed. However, in some technologies, the fluid inside the reservoir vibrates violently with vehicle movement, generating noise and potentially shortening the reservoir's lifespan.

[0059] In view of this, this application proposes a brake fluid reservoir 100, Figures 1 to 7 This is a schematic diagram of a structure of a brake fluid reservoir 100 provided in this application. The brake fluid reservoir 100 provided in this application has low noise, high structural strength, and long service life. The brake fluid reservoir 100 will be described in detail below with reference to the main drawings.

[0060] According to the first aspect of this application, referring to Figure 1 and Figure 2This application provides a brake fluid reservoir 100, including a reservoir body 10 and a plurality of flow-blocking plates, wherein the plurality of flow-blocking plates include a plurality of first flow-blocking plates 21 and a plurality of second flow-blocking plates 22; the reservoir body 10 forms a receiving cavity 11, the receiving cavity 11 being configured to store brake fluid; the plurality of first flow-blocking plates 21 are spaced apart in the receiving cavity 11 along a second direction, and the plurality of second flow-blocking plates 22 are spaced apart in the receiving cavity 11 along a first direction, so as to divide the receiving cavity 11 into a plurality of interconnected sub-cavities 111; wherein the first direction intersects the second direction.

[0061] In the technical solution of this application, the reservoir 10 has a receiving cavity 11 configured to store brake fluid. Multiple first baffles 21 are spaced apart along a first direction in the receiving cavity 11, and multiple second baffles 22 are spaced apart along a second direction in the receiving cavity 11. The arrangement of the multiple first baffles 21 and multiple second baffles 22 divides the receiving cavity 11 into multiple interconnected sub-chambers 111, allowing the brake fluid to be stored separately in each sub-chamber 111. This prevents significant sloshing of the brake fluid during vehicle operation, maintains the stability of the brake fluid within the reservoir 10, and reduces noise generated by brake fluid sloshing. Simultaneously, reducing the sliding amplitude of the brake fluid prevents it from repeatedly impacting the reservoir 10, thus extending the service life of the reservoir 10. The multiple first baffles 21 and multiple second baffles 22 disposed in the receiving cavity 11 also improve the structural strength of the reservoir 10, thereby extending the service life of the brake fluid reservoir 100.

[0062] It should be noted that the first direction intersects with the second direction, the first direction intersects with the third direction, and the second direction intersects with the third direction. The first direction, the second direction, and the third direction lie in different planes. The included angle between any two of the first direction, the second direction, and the third direction is not limited and can be 80°, 85°, 90°, 95°, or 100°. In the following embodiments, the included angle between any two of the first direction, the second direction, and the third direction is 90°, that is, some embodiments of this application are explained by establishing a spatial rectangular coordinate system using the first direction, the second direction, and the third direction. It should be emphasized that the included angle between any two of the first direction, the second direction, and the third direction is 90° and does not constitute a limitation on the following embodiments of this application. More specifically, in this embodiment, taking the pot body 10 as an example, the first direction is the length direction of the pot body 10, the second direction is the width direction of the pot body 10, and the third direction is the height direction of the pot body 10. Hereinafter, the brake fluid pot 100 provided by this application will be explained using the first direction as the length direction of the pot body 10 as an example.

[0063] Please see Figure 1 , Figure 2 and Figure 3In some embodiments, at least two of the sidewall of the vessel body 10, the first baffle plate 21, and the second baffle plate 22 form sub-chambers 111. The formation of the sub-chambers 111 is not limited and can be selected according to the actual situation.

[0064] In some embodiments, one end of a portion of the baffle plate is connected to the side wall of the receiving cavity 11 to improve the structural strength of the baffle plate and prevent the baffle plate from bending and deforming.

[0065] Please continue reading. Figure 3 In some embodiments, one end of the first baffle plate 21 is connected to the inner wall of the receiving cavity 11. When the first baffle plate 21 is connected to the turning point of the inner wall of the receiving cavity 11, the first baffle plate 21, the inner wall of the receiving cavity 11 arranged in the first direction and the inner wall of the receiving cavity 11 arranged in the second direction enclose a sub-cavity 111.

[0066] Please continue reading. Figure 3 In some embodiments, a portion of the first baffle plate 21 and a portion of the second baffle plate 22 are disposed in the middle of the receiving cavity 11, and the portion of the first baffle plate 21 and the portion of the second baffle plate 22 are connected to form a sub-cavity 111. Specifically, there are two first baffle plates 21 and one second baffle plate 22. The second baffle plate 22 is disposed between the two first baffle plates 21, and both ends of the second baffle plate 22 are respectively connected to the same end of the two first baffle plates 21. The two first baffle plates 21 and the second baffle plate 22 form a sub-cavity 111.

[0067] Please continue reading. Figure 3 In some embodiments, one end of a portion of the second baffle plate 22 is connected to the inner wall of the receiving cavity 11. When the second baffle plate 22 is connected to the turning point of the inner wall of the receiving cavity 11, the second baffle plate 22, the inner wall of the receiving cavity 11 arranged in the first direction, and the inner wall of the receiving cavity 11 arranged in the second direction enclose a sub-cavity 111.

[0068] Please continue reading. Figure 3 In some embodiments, one end of a portion of the first baffle plate 21 is connected to one end of a portion of the second baffle plate 22. More specifically, there are two first baffle plates 21 and two second baffle plates 22. The two first baffle plates 21 are arranged opposite to each other, and the two second baffle plates 22 are arranged between the two first baffle plates 21. The two first baffle plates 21 and the two second baffle plates 22 are connected end to end to form a sub-chamber 111.

[0069] Please continue reading. Figure 3In some embodiments, one end of the first baffle plate 21 is connected to the inner wall of the receiving cavity 11, and one end of the second baffle plate 22 is connected to the inner wall of the receiving cavity 11. A sub-cavity 111 is formed between the first baffle plate 21, the second baffle plate 22, and the cavity wall of the receiving cavity 11.

[0070] In some embodiments, the pot body 10 includes two first side edges 12 disposed opposite to each other along a first direction and two second side edges disposed opposite to each other along a second direction, the two second side edges 13 being disposed between the two first side edges 12, and the two first side edges 12 and the two second side edges 13 forming at least a portion of the receiving cavity 11.

[0071] Specifically, in some embodiments, at least one first baffle plate 21 is connected to a corresponding first side 12. This arrangement improves the connection strength of the multiple first baffle plates 21. When the vehicle is moving and the vibration amplitude is large, the brake fluid will sway back and forth significantly within the receiving cavity 11, causing severe impact on the cavity wall and the first baffle plates 21. Placing multiple first baffle plates 21 on the first side 12 improves the connection strength between the first baffle plates 21 and the inner wall of the receiving cavity 11, thereby resisting the impact force caused by the brake fluid. Of course, the first baffle plates 21 may not be located on the first side 12. When the car encounters an obstacle at high speed on the road, due to inertia, the brake fluid in the brake fluid reservoir 100 will sway back and forth significantly, causing severe impact on the first baffle plates 21, which may easily lead to deformation or even breakage of the first baffle plates 21.

[0072] Similarly, at least one second baffle plate 22 is connected to the corresponding second side 13. This arrangement can improve the connection strength of the second baffle plate 22. When the vehicle is moving and the vibration amplitude is large, the brake fluid will shake back and forth in the receiving cavity 11, causing a violent impact on the cavity wall of the receiving cavity 11 and the second baffle plate 22. By setting multiple second baffle plates 22 on the second side 13, the connection strength between the second baffle plate 22 and the inner wall of the receiving cavity 11 can be improved, thereby resisting the impact force caused by the brake fluid.

[0073] Furthermore, the arrangement of the first baffles 21 is not limited and can be determined according to the size of the receiving cavity 11. For example, in some embodiments, two first baffles 21 arranged opposite each other along the first direction are staggered. In other embodiments, every two oppositely arranged first baffles 21 are located on the same axis. Specifically, in this application, multiple first baffles 21 are arranged in a staggered manner, with multiple first baffles 21 located on the two first sides 12 staggered from each other. Taking one pair as an example, one first baffle 21 is located on one of the first sides 12, and the other first baffle 21 is located on the other first side 12. The orthographic projections of the two first baffles 21 on the same first side 12 are staggered. This arrangement increases the distance between the two first baffles 21, allowing the brake fluid to flow quickly into the multiple sub-chambers 111.

[0074] Similarly, in some embodiments, two second baffles 22 arranged opposite each other along the second direction are staggered. In other embodiments, every two oppositely arranged second baffles 22 are located on the same axis. Specifically, in this application, a plurality of second baffles 22 are arranged in a staggered manner, with the plurality of second baffles 22 located on the two second sides 13 being staggered from each other. Taking one pair as an example, one second baffle 22 is located on one of the second sides 13, and the other second baffle 22 is located on the other second side 13. The orthographic projections of the two second baffles 22 on the same second side 13 are staggered. This arrangement can increase the distance between the two second baffles 22, allowing the brake fluid to flow quickly into the plurality of sub-chambers 111.

[0075] In some embodiments, to ensure interconnection between the multiple sub-chambers 111, allowing brake fluid to fill the entire receiving cavity 11, adjacent sub-chambers 111 are interconnected through a connecting port 20. This configuration divides the receiving cavity 11 into multiple sub-chambers 111 by multiple first baffles 21 and multiple second baffles 22, each sub-chamber 111 being not completely sealed, thereby maintaining the stability of the brake fluid within the receiving cavity 11. Simultaneously, the connecting port also reduces the flow rate of the brake fluid within the sub-chambers 111, ensuring the stability of the brake fluid level, reducing friction between the brake fluid and the reservoir body 10, the first baffles 21, and the second baffles 22, and preventing frictional heating that could lead to impurities in the brake fluid.

[0076] It should be noted that the location of the connecting hole is not limited. For example, among the multiple first flow deflectors 21, only one first flow deflector 21 has a connecting hole 20. Alternatively, each of the multiple first flow deflectors 21 may have a connecting hole 20. Yet another example is that some of the multiple first flow deflectors 21 may have a connecting hole 20, while others may not. Similarly, among the multiple second flow deflectors 22, only one second flow deflector 22 has a connecting hole 20; or, each of the multiple second flow deflectors 22 may have a connecting hole 20; or, some of the multiple second flow deflectors 22 may have a connecting hole 20, while others may not.

[0077] It should be noted that the number of connecting ports 20 is not limited and can be set according to the size and number of sub-chambers 111. In some embodiments, the same first baffle plate 21 is provided with at least two connecting ports 20. In this way, it can be ensured that the brake fluid quickly fills each sub-chamber 111; when one connecting port 20 is blocked, the brake fluid can still flow into this sub-chamber 111 from the other connecting port 20.

[0078] Furthermore, in some embodiments, at least two connecting ports 20 located on the same first baffle plate 21 are staggered in the third direction. The staggered arrangement can avoid stress concentration, improve the structural strength of the first baffle plate 21, and prevent the first baffle plate 21 from bending, deforming, or even breaking due to the impact force of the brake fluid.

[0079] Similarly, the same second baffle plate 22 is provided with at least two connecting ports 20. This ensures that the brake fluid can quickly fill each sub-chamber 111; when one connecting port 20 is blocked, the brake fluid can still flow into this sub-chamber 111 from the other connecting port 20.

[0080] Furthermore, in some embodiments, at least two connecting ports 20 located on the same second baffle plate 22 are staggered in the third direction; the staggered arrangement can avoid stress concentration, improve the structural strength of the second baffle plate 22, and prevent the first baffle plate 21 from bending, deforming, or even breaking due to the impact force of the brake fluid.

[0081] The arrangement of the kettle body 10 is not limited; it can be integrally molded or made in parts. Considering the difficulty of the molding process, in this embodiment, please refer to... Figure 4 and Figure 5The pot body 10 includes an upper shell 14 and a lower shell 15, which together form at least a part of the receiving cavity 11. During assembly, the mating surfaces of the upper shell 14 and the lower shell 15 have allowance, and the upper shell 14 and the lower shell 15 can be welded together by hot melt welding.

[0082] Specifically, for ease of molding, each first baffle plate 21 includes a separately configured first sub-baffle plate 212 and a second sub-baffle plate 213. The first sub-baffle plate 212 is connected to the upper housing 14, and the second sub-baffle plate 213 is connected to the lower housing 15. Each second baffle plate 22 includes a separately configured third sub-baffle plate 222 and a fourth sub-baffle plate 223. The third sub-baffle plate 222 is connected to the upper housing 14, and the fourth sub-baffle plate 223 is connected to the lower housing 15. During molding, the multiple first sub-baffle plates 212 and the multiple third sub-baffle plates 222 are integrally formed with the upper housing 14, and the multiple second sub-baffle plates 213 and the multiple fourth sub-baffle plates 223 are integrally formed with the lower housing 15.

[0083] Please see Figure 4 The distance between two adjacent first baffles 21 is L1, and the length of the reservoir 10 is L0, where 0 < L1 / L0 < 1 / 6. It should be noted that if the distance L1 is too small, the number of first baffles 21 increases, occupying a larger area of ​​the receiving cavity 11, resulting in a decrease in the volume of brake fluid within the receiving cavity 11. If the distance L1 is too large, the area of ​​the sub-chamber 111 increases. When the vehicle encounters an obstacle at high speed on the road, due to inertia, the brake fluid will sway violently back and forth within the sub-chamber 111, causing severe impact on the inner wall of the brake fluid reservoir 100. This seriously affects the strength and service life of the brake fluid reservoir 100, generating swaying noise. Furthermore, the significant swaying of the brake fluid may prevent it from flowing out continuously and normally.

[0084] Please continue reading. Figure 4 The distance between two adjacent second baffles 22 is H1, and the width of the reservoir 10 is H0, where 0 < H1 / H0 < 1 / 6. Similarly, if the distance H1 is too small, the number of second baffles 22 increases, occupying a larger area of ​​the receiving cavity 11, resulting in a decrease in the volume of brake fluid in the receiving cavity 11. If the distance H1 is too large, the area of ​​the sub-chamber 111 increases. When the vehicle encounters an obstacle at high speed on the road, due to inertia, the brake fluid will sway back and forth significantly in the sub-chamber 111, causing a violent impact on the inner wall of the brake fluid reservoir 100, seriously affecting the strength and service life of the brake fluid reservoir 100, generating shaking noise, and the large-scale shaking of the brake fluid may prevent the brake fluid from flowing out normally and continuously.

[0085] Within the aforementioned range, L1 and H1 can control the amount of brake fluid sloshing during vehicle operation, reduce the noise generated by sloshing, and simultaneously enhance the overall strength of the brake fluid reservoir 100.

[0086] Please see Figure 1 The brake fluid reservoir 100 also includes an outlet pipe 30 and an inlet pipe 40, which are respectively connected to at least one sub-chamber 111. The inlet pipe 40 is configured to inject brake fluid into the reservoir 10, and the outlet pipe 30 is configured to transfer the brake fluid in the reservoir 10 to other components.

[0087] It should be noted that in related technologies, there are multiple 90-degree angles between the inlet pipe 40 and the vessel body 10. In this embodiment, the inlet pipe 40 is inclined relative to the vessel body 10. Furthermore, the included angle between the inlet pipe 40 and the vessel body 10 is greater than 90° but less than 180°. This design facilitates oil filling, makes it easier for the oil gun to enter, and reduces backflow of the oil gun after filling.

[0088] Please see Figure 2 The inlet pipe 40 has an outlet 42. The inlet pipe 40 includes a side wall and a bottom wall. The bottom wall is connected to one end of the side wall to form an oil chamber. The outlet 42 is formed on the side wall and located inside the reservoir 10. With this design, when the reservoir 10 shakes violently during sudden braking, acceleration, left turns, and right turns, the brake fluid in the containment chamber 11 will not overflow to the outside of the reservoir 10 due to the obstruction of the inlet pipe 40, regardless of whether the brake fluid level is at the maximum or minimum mark.

[0089] Please see Figure 1 , Figure 6 and Figure 7 The brake fluid reservoir 100 also includes a reservoir cap 50 and a seal 60. The reservoir cap 50 covers the oil inlet 41 of the inlet pipe 40, and the seal 60 abuts between the reservoir cap 50 and the inlet pipe 40. In this embodiment, during assembly, the mating surfaces of the upper housing 14 and the lower housing 15 are left with allowance, and the upper housing 14 and the lower housing 15 can be welded together using thermofusion welding to form the reservoir body 10. Then, the filter screen 43 assembly is placed at the inlet of the reservoir body 10. The seal 60, assembled with the reservoir cap 50, serves both as a sealing and fastening function and as a ventilation function. Next, the reservoir cap 50 is screwed into the inlet pipe 40 of the brake fluid reservoir 100, and a dust cap is added to complete the assembly of the brake fluid reservoir 100. The brake fluid reservoir 100 can be used to store brake fluid. Brake fluid enters through the inlet pipe 40 on the upper body of the brake fluid reservoir 100, is filtered through the filter screen 43, and is stored in the brake fluid reservoir 100. When the vehicle's braking system needs to be replenished with brake fluid, it enters the pipeline through the outlet of the brake fluid reservoir 100 to replenish brake fluid to other parts of the system.

[0090] Furthermore, to ensure that the brake fluid in the brake fluid reservoir 100 can flow out continuously and smoothly when needed, a venting groove 51 is formed on the reservoir cap 50; a venting cutout 61 is provided on the sealing member 60; the venting cutout 61 is configured to connect the venting groove 51 and the receiving cavity 11 or to block the connection between the venting groove 51 and the receiving cavity 11. This configuration can maintain the pressure difference balance inside and outside the brake fluid reservoir 100, allowing the brake fluid to flow out smoothly.

[0091] More specifically, when the air pressure inside the kettle body 10 is greater than or less than the air pressure outside the kettle body 10, the ventilation opening 61 is opened, and the ventilation groove 51 is connected to the receiving cavity 11; when the air pressure inside the kettle body 10 is equal to the air pressure outside the kettle body 10, the ventilation opening 61 is closed, and the ventilation groove 51 is disconnected from the receiving cavity 11.
