[0003] Original equipment manufacturers or contract manufacturers always have requirements for the clearance between the reservoir in the engine compartment and the surrounding parts, and there is a trend that the height of the engine compartment is getting lower. Generally speaking, the clearance in the Z direction (height direction) is crucial for the layout of the reservoir. In previous technical solutions, the lowest height of the used reservoir was 40.4 millimeters. Summary of the Utility Model

[0004] According to different aspects, an object of the present disclosure is to construct a brake fluid reservoir that can have a lower height while performing its inherent functions and can meet the increasingly tight accommodation space for the reservoir.

[0005] In addition, an object of the present disclosure is to solve or at least alleviate one or more problems existing in the prior art.

[0006] The present disclosure solves the above problems by providing a brake fluid reservoir and a braking system. Specifically, according to one aspect of the present disclosure, there is provided:

[0015] It is easily understood that according to the technical solution of the present disclosure, without changing the essential spirit of the present disclosure, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following detailed description and the accompanying drawings are only exemplary descriptions of the technical solution of the present disclosure, and should not be regarded as the whole of the present disclosure or as a limitation or restriction on the technical solution of the present disclosure.

[0016] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for descriptive and differentiating purposes, and should not be understood as indicating or implying the relative importance of the corresponding components.

[0017] Reference Figures 1 to 3 , wherein, Figure 1 Shows a front view of a brake fluid reservoir according to the present disclosure; Figure 2 Shows a bottom view of a brake fluid reservoir according to the present disclosure; and Figure 3 Shows a side view of a brake fluid reservoir according to the present disclosure.

[0018] The brake fluid reservoir 100 includes a base plate 1, a connection structure for connecting to a brake, a liquid inlet portion 2 for introducing brake fluid, and a liquid outlet portion 3 for discharging brake fluid. The connection structure, the liquid inlet portion 2, and the liquid outlet portion 3 are constructed on the base plate 1. The base plate 1 can be arranged on the brake, the liquid outlet portion 3 can be inserted into the brake, and the exposed height of the brake fluid reservoir 100 relative to the brake is configured such that the brake fluid reservoir 100 can be arranged in the engine compartment of the vehicle.

[0019] It should be understood that Figure 1 from a perspective, the left - right direction can be the front - rear direction of the vehicle, and the in - paper and out - of - paper directions can be the left - right direction of the vehicle. In addition, the brake fluid reservoir is sometimes also called an oil pot or a reservoir tank. The specific type of brake fluid is not limited, including alcohol - type brake fluid, mineral - oil - type brake fluid, synthetic - type brake fluid, etc. Correspondingly, the liquid inlet portion is sometimes also called an inlet pipe or has an oil inlet, and the liquid outlet portion is sometimes also called an outlet pipe or has an oil outlet. The brake can be understood as a brake booster system / assembly in a broad sense, or as a brake (master) cylinder or a hydraulic unit in a narrow sense.

[0020] In this technical solution, the reservoir is connected to the brake via the connection structure and, when needed, inputs brake fluid into the brake via the liquid inlet portion and the liquid outlet portion, for example, to provide braking assistance for the driver. In terms of the relative positional relationship with the brake, the liquid outlet portion can extend into the brake, and the base plate of the reservoir is located on the brake. That is to say, in the state where the reservoir and the brake are assembled, from the height direction, the height by which the reservoir exceeds the brake is equivalent to the height starting from the bottom surface of the base plate upwards.

[0021] As described in the background art, the accommodation space for the reservoir is becoming increasingly limited. Especially for some vehicle models (such as sports cars), there are relatively strict height requirements. And the position of the brake is usually predetermined according to the position of the brake pedal and is not easy to change. Therefore, what can be adjusted is the height of the brake fluid reservoir so that it can smoothly meet the available accommodation space. For this purpose, the present technical solution defines that the exposed height of the brake fluid reservoir 100 relative to the brake is configured such that the brake fluid reservoir 100 can be arranged in the engine compartment of the vehicle. That is to say, through this technical solution, those skilled in the art are guided to adapt to various types of vehicle models and the corresponding height (or vertical dimension) of the engine compartment by adjusting this exposed height. Especially for engine compartments with relatively strict height requirements such as sports cars, it can have a lower height while performing its inherent functions and can meet the increasingly tight accommodation space for the reservoir. In this regard, those skilled in the art can know how to define and set this exposed height according to the actual structure of the reservoir and its connection method or relative position relationship with surrounding parts (the brake). On the other hand, in some vehicle models or when the accommodation space in the engine compartment is large and there are no strict requirements for the height of the reservoir, it can be considered that the exposed height of the reservoir can be set relatively high to increase the accommodation capacity and transmission flow rate of the brake fluid.

[0022] The height of this accommodation space is, for example, within 20 millimeters, such as 18 to 20 millimeters. In some embodiments, the exposed height of the brake fluid reservoir relative to the brake is less than 20 millimeters. That is, from the height direction of the vehicle, starting from the bottom surface of the reservoir substrate and going upward, the height of this part of the reservoir is less than 20 millimeters, so it can meet the requirements of a compact accommodation space. If necessary, the height of this part can be further adjusted. Taking Figure 1 the structure as an example, this height can be made 17.5 millimeters or less, with strong compactness. Thus, it can be seen that when the height requirements are met, those skilled in the art can flexibly adjust the shape, structure, size, positional layout of each component, manufacturing process, etc. of the reservoir and its components to play the original role of the reservoir and can also be adapted to various vehicle models.

[0023] In some embodiments of the present disclosure, the number of the liquid outlet portions 3 is at least three and they are not all on the same straight line. The brake fluid reservoir 100 further includes a demolding portion 4 formed on the substrate 1. The liquid inlet portion 2 and the demolding portion 4 are configured as hollow straight pipes, and each liquid outlet portion 3 is either communicated with the liquid inlet portion 2 or the demolding portion 4.

[0024] This technical solution can be combined with Figure 2For better understanding, it should be noted that each liquid outlet or oil outlet can communicate with different chambers of the brake to achieve different functions. The number of liquid outlets is arbitrary, and in this example, it is at least three. Figure 2 Taking three as an example for illustration. Among them, Figure 2 The two liquid outlets on the left and in the middle are on a straight line, and the two liquid outlets in the middle and on the right are on another straight line. Therefore, a special structure needs to be set up to ensure the smooth progress of the demolding process. Here, the demolding part plays such a role.

[0025] It can also be understood that the demolding process can be a part of the injection molding process. In the demolding stage, for example, it can take out the product that has been cold-set and formed from the mold, and the product already has or basically has the shape of the final product. Since the liquid outlets are not all on the same straight line, in order to better carry out the demolding process, the technical solution designs a linear demolding part, and also designs the liquid inlet part to be linear, making full use of existing resources, so that the liquid inlet part has the dual functions of facilitating demolding and liquid inlet during the subsequent use process. Specifically, the design of the linear demolding part and liquid inlet part can help simplify the mold structure and make the demolding process smoother. The linear structure is usually easier to separate from the mold, reducing the resistance and difficulty during demolding. In addition, when the demolding part or the liquid inlet part is communicated with the liquid outlet part (that is, it is necessary to ensure that each liquid outlet is communicated with one of the liquid inlet part or the demolding part), this design also considers the layout of the internal flow channels of the mold to ensure that during the injection molding or forming process, the material can flow smoothly to each part and can be easily separated during demolding. The linear structure is easy to process and manufacture, and at the same time helps to improve the reliability and service life of the product. In addition, the characteristics of the injection molding process include supporting complex part design, high-efficiency production, high strength and durability, flexibility and diversity, waste reduction, low labor cost, creating lightweight products, high precision and consistency, wide material applicability, supporting automated production, etc. Those skilled in the art can make selections according to specific requirements and conditions. In some other feasible ways, welding can also be considered for connecting parts. It can also be understood that if several liquid outlets are all on the same straight line, the design of the demolding part can be cancelled, and instead, a straight pipe-shaped liquid inlet part is used to realize demolding by connecting it with all the liquid outlets. Here, the liquid inlet part has the dual functions of liquid inlet and facilitating demolding, making use of existing resources, not imposing an extra burden on the reservoir, and controlling the cost.

[0026] In order to realize the connection between the reservoir and the brake, in some embodiments, the connection structure includes a first connection part 6 and a second connection part 7. The first connection part 6 is constructed on the first side of the substrate 1 and can be connected to the brake through a threaded fastener. The second connection part 7 is constructed on the second side of the substrate 1 and can be connected to the brake through a pin.

[0027] Threaded fasteners generally refer to components that achieve fastening connections through threaded mating, such as bolts, screws, etc. Thus, this technical solution adopts multiple connection methods and connection parts to enhance the stability of the connection. Among them, threaded connection has the advantages of compact structure, convenient disassembly and assembly, reliable connection, etc., and can provide strong connection force and reliability, ensuring that the connected components remain stable under dynamic or static loads; at the same time, pin connection increases the redundancy and stability of the connection and also has a certain load-bearing capacity. In addition, both threaded and pin connections have relatively high precision. By combining these two connection methods, it can be ensured that the connection structure meets relatively high precision requirements during assembly, thus guaranteeing the normal operation and performance of the brake. For this reason, it can also be understood that both the first connection part and the second connection part can be configured with through holes or said holes for threaded fasteners and pins to pass through respectively.

[0028] The multiple connection method is also more suitable for hydraulic units that are usually relatively larger in volume and weight. In addition, it can disperse stress, reduce the risk of single-point stress, and improve the overall strength and durability of the connection structure. Finally, the combination use of threaded fasteners and pins is a detachable connection, making the brake system more convenient for maintenance and replacement. If a certain component needs to be replaced or repaired, disassembly and installation can be achieved through threaded fasteners and pins respectively.

[0029] Of course, those skilled in the art can adjust the connection method and position according to specific requirements to adapt to different installation and layout requirements.

[0030] Combined Figures 1 to 3 It can also be seen that the first connection part 6 is a lug structure and is constructed on the bottom surface (such as the left end of the bottom surface) of the substrate 1, the second connection part 7 is a cantilever structure and is constructed on the top surface (such as the right end of the top surface) of the substrate 1, the liquid inlet part 2 is constructed on the top surface of the substrate 1, and the liquid outlet part 3 is constructed on the bottom surface of the substrate 1.

[0031] Here, the lug structure can be understood as a structure extending downward from the bottom surface of the substrate. In this example, it presents as a combination of a rectangle and an arc, with a through-hole 61 provided and reinforcing structures 62 constructed on both sides. On the other hand, the cantilever structure can be understood as a structure extending outward from the top surface of the substrate beyond the substrate, that is, having a part suspended in the air. Considering the strength requirements, in this example, the cantilever structure is formed by two side walls 71 with a certain thickness and a bottom edge 72 connecting between the two side walls. Through-holes 73 are constructed at the outer ends of the side walls, and a reinforcing plate 74 parallel to the bottom edge is also constructed between the side walls. A cross-shaped reinforcing rib 75 is also constructed on the outer side of the side walls. The cantilever structure usually has good load-bearing capacity and stiffness, which can ensure the stability and reliability of the connection. It can also be seen that the height of the cantilever structure is higher than that of the liquid inlet part and the demolding part. Therefore, the exposed height of the liquid reservoir is equivalent to the height between the bottom surface of the substrate and the top surface of the second connecting part.

[0032] In addition, the arrangement where the liquid inlet part is located on the top surface and the liquid outlet part is located on the bottom surface helps the process of delivering the brake fluid to the brake via the liquid inlet part and the liquid outlet part, optimizes the fluid flow path, reduces the difficulty and complexity of pipeline layout, ensures the smooth flow of the fluid inside the liquid reservoir, reduces energy loss and pressure drop. This design also helps to improve the overall performance and efficiency of the supercharger and the braking system and extends its service life. At the same time, this layout also helps to improve the compactness of the equipment, saves installation space, and helps to meet the limited accommodation space height resources.

[0033] Generally speaking, this technical solution can enhance the stability and support force of the structure, optimize the space utilization and layout, facilitate installation and maintenance, and help to reduce equipment failures and damages caused by factors such as vibration and impact, improving the safety and reliability of the equipment.

[0034] It should be noted that also for the reason of height control, in some application scenarios or technical methods, the second connecting part can also be constructed on the bottom surface of the substrate (such as the right end of the bottom surface) and connected to the corresponding part of the brake. In this way, the exposed height of the liquid reservoir is equivalent to the distance in the height direction from the bottom surface of the substrate to the top end of the liquid inlet part or the demolding part (if any), and the exposed height of the liquid reservoir can be further reduced accordingly, preparing for the increasingly strict accommodation space.

[0035] As mentioned above, the brake fluid reservoir is sometimes also called an oil pot. In a specific feasible solution, the brake fluid reservoir 100 is a proximal oil pot relative to the brake, and the liquid inlet part 2 is used to introduce the brake fluid from a distal oil pot relative to the brake.

[0036] One possibility that this technical solution can provide is that the distal oil pot is responsible for storing a relatively large amount of brake fluid and delivering it to the proximal oil pot when needed. Therefore, the brake fluid reservoir serving as the proximal oil pot does not need to be constructed with a too large accommodation space for storing brake fluid, enabling the volume of the reservoir to be made smaller and also contributing to the reduction of the height of the reservoir.

[0037] The design of the proximal oil pot can also shorten the flow path of the brake fluid from the reservoir to the brake. This can reduce the energy loss and pressure drop during the flow of the brake fluid, improving the response speed and efficiency of the braking system; while the distal oil pot, as the source of the brake fluid, can ensure that the braking system always has sufficient brake fluid supply, avoiding the decline or failure of the braking performance caused by insufficient brake fluid during braking. In addition, the differentiated design of the distal and proximal oil pots provides more flexibility and adjustability in the layout space for the two, which can meet the requirements of different vehicle models and braking system layouts.

[0038] Reference Figure 4 and Figure 5 , in which, Figure 4 shows a perspective view of another brake fluid reservoir according to the present disclosure; and Figure 5 shows a cross-sectional view of another brake fluid reservoir according to the present disclosure.

[0039] As mentioned above, the present disclosure provides the feasibility of constructing the reservoir through an injection molding process in cooperation with a demolding part. Further, the brake fluid reservoir 100 further includes a plug 5, and the plug 5 sealingly plugs the pipe orifice of the demolding part 4. Among them, in Figure 5 the position of the plug is roughly indicated by a dotted-line square.

[0040] It should be understood that the shape of the plug can be matched with the shape of the demolding part to facilitate the sealing function. For example, if the demolding part is a circular straight pipe, the plug has a corresponding circular part. The circular shape matching can achieve better sealing performance. When necessary, a square, triangular or irregular shape matching method can also be adopted.

[0041] It should also be understood that the plug is installed and seals the pipe orifice of the demolding portion after the demolding process is completed, for example, during the actual use of the product. This is because during the operation of the liquid reservoir, the brake fluid can be transmitted through the liquid inlet portion. The present technical solution constructs a plug to seal its pipe orifice. Sealing the pipe orifice can prevent the oil from leaking out of the liquid reservoir in the following two scenarios: One scenario is that when the vehicle factory fills the liquid from a remote oil pot, for example, the means adopted is vacuum filling, which requires the entire system to be airtight; another scenario is in the normal working state. Since the proximal oil pot is at a low point in some embodiments, if there is an opening, the oil at the distal end will leak out under the action of gravity. In addition, sealing the pipe orifice can also prevent contamination of the liquid reservoir or the liquid outlet portion (for example, brake fluid mixing with air). Of course, if the liquid reservoir needs to cooperate with multiple remote oil pots simultaneously, the plug can be considered to be removed, and the demolding portion is connected to one of the remote oil pots, so that the demolding portion also has the dual functions of facilitating demolding and transporting the brake fluid.

[0042] It can also be seen that a plate body 51 is formed at the exposed end of the plug, which is convenient for operation by staff or automated tools such as manipulators, for example, installing the plug onto the pipe orifice or disassembling it from the pipe orifice. Regarding the installation method of the plug, the present disclosure does not make any special restrictions, and processes such as hot melting and welding can be used to install it. Among them, the orientation of the plate body can be considered to be set parallel to the substrate or horizontally, so that the height is relatively low and will not affect the exposed height of the liquid reservoir.

[0043] Combined with Figure 5 It can also be clearly seen that the liquid inlet portion 2 and the demolding portion 4 form a manifold. Here, the manifold means that the liquid inlet portion and the demolding portion share or have a common basic pipe portion, and two branch pipe portions extend from this basic pipe portion. These two branch pipe portions respectively form the liquid inlet portion and the demolding portion with the basic pipe portion, and Figure 5 it presents a Y-shaped structure in []. Through this technical solution, the liquid inlet portion and the demolding portion are more compact as a whole, integrating the liquid inlet and demolding functions together, reducing the number and complexity of the pipes in the mold, reducing the dead corners and difficult-to-demold areas inside the mold, simplifying the demolding process, also contributing to reducing the overall production cost, and to a certain extent improving the economic efficiency of production. In addition, this integrated design can create a fluid circulation. Through this fluid circulation in the manifold, the mold temperature can be more effectively controlled, thereby shortening the cooling time and improving the product quality. A faster cooling time means that the demolding process can start earlier, thus improving the demolding efficiency. It can also be understood that the number of the branch pipe portions and the basic pipe portion can vary adaptively according to the number of the liquid inlet portion and the demolding portion. Also, exemplarily, the liquid inlet portion and the demolding portion can also present as a T-shaped, L-shaped, U-shaped, V-shaped or an arrangement combination of these or the above shapes, etc., for example, it can be determined according to the number and position layout of the liquid outlet portion, as long as it can connect the liquid outlet portion and support demolding.

[0044] The present disclosure also relates to a braking system. Among them, the braking system includes any one of the above-mentioned brake fluid reservoirs 100 and a brake. The substrate 1 is arranged on the brake, the connecting structure is connected to the brake, and the liquid outlet portion 3 is inserted into the brake. Thus, various embodiments of the braking system and the corresponding technical effects can inherit the relevant content described above for the brake fluid reservoir, and will not be elaborated here. Since the height of the brake fluid reservoir is controlled, it can not only be applicable to more stringent spaces, but also make the entire braking system more compact.

[0045] Regarding the layout of the braking system, exemplarily, the braking system is arranged in the engine compartment of the vehicle and adjacent to the firewall of the vehicle. Since the space in the engine compartment of the vehicle, especially in some models such as sports cars, is tight, and the height of the brakes in the compartment is usually fixed, the present disclosure has a brake fluid reservoir with a lower height and the entire braking system can have stronger adaptability and compatibility. Thus, this design can also make the overall structure of the vehicle more compact, contribute to saving the interior space of the vehicle, and make the vehicle design more reasonable and efficient.

[0046] Also as described above, there can be multiple liquid outlet portions, and each liquid outlet portion can communicate with different chambers of the brake or the master cylinder. Specifically, the liquid outlet portions 3 respectively lead to the first chamber of the brake master cylinder, the second chamber of the brake master cylinder, and the boost chamber of the brake master cylinder, which can ensure that each chamber can obtain the required brake fluid supply, improve the braking efficiency, and can supply oil to the boost chamber through the brake fluid reservoir during emergency braking or when greater braking force is required, so as to provide the necessary hydraulic support and enhance the driving safety.

[0047] Those skilled in the art should understand the meanings of the first chamber and the second chamber. For example, in a dual-chamber brake master cylinder, it is configured as a piston cylinder unit, where the first chamber can be connected to a group of brake wheel cylinders, and the second chamber is connected to another group of brake wheel cylinders to achieve the distribution of braking force and improve the stability and safety of the braking system. In addition, the number, relative positional relationship, corresponding relationship with the chambers, etc. of the liquid outlet portions of the brake fluid reservoir can also be adaptively adjusted according to the chamber design of the master cylinder of the brake to be matched to support the operation of the brake.

[0048] It should be understood that all the above preferred embodiments are exemplary rather than restrictive, and all modifications or deformations made by those skilled in the art to the specific embodiments described above under the concept of the present disclosure should be within the legal protection scope of the present disclosure.
