[0034] The brake fluid container and system described in this utility model will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, such explanation and description do not constitute an undue limitation on the technical solution of this utility model.

[0035] Figure 1 An exemplary brake fluid system is shown. For example... Figure 1 As shown, the brake fluid system includes a valve assembly 200 and a brake fluid reservoir 100 mounted on top of a valve housing 210 of the valve assembly 200. The brake fluid reservoir 100 is detachably mounted on top of the valve housing via a connecting structure 300. Figure 1As shown, one current solution involves a connecting structure constructed with a connecting piece having a connecting hole and a bolt 301 inserted into the connecting hole. However, this method requires the installation and removal of at least two connecting bolts during disassembly, making the process relatively complex.

[0036] To address this problem, this invention provides a brake fluid container in one embodiment that can be easily and securely installed with the valve assembly of a brake fluid system, and is inexpensive.

[0037] Figure 2 The image shows a front view of the brake fluid system according to one embodiment of the present invention.

[0038] like Figure 2 As shown, in some embodiments, the brake fluid system of this invention includes a valve assembly 200, which has a control lever 220. The control lever 220 is connected to the vehicle's brake pedal via a slider (not shown), thereby transmitting received braking commands to the valve assembly 200.

[0039] The main structure of the valve assembly is a hollow valve housing 210, and the brake fluid container 100 is detachably mounted on the top surface of the valve housing 210. The brake fluid container is used to store brake fluid and may include a housing with a screw cap. The housing may also contain a filter and a level indicator. The housing of the brake fluid container has a bottom surface 110 for connection with the valve housing 210 of the brake fluid system.

[0040] Figure 3 The diagram shows the structure of the bottom surface of the brake fluid container according to one embodiment of the present invention.

[0041] Figure 4 Showing Figure 3 A-direction view.

[0042] like Figure 3 and Figure 4 As shown, the bottom surface 110 of the brake fluid container 100 is provided with: a first connecting portion 400 extending downward from the bottom surface in the height direction Z, and a second connecting portion 500 extending downward from the bottom surface in the height direction Z. Figure 2 As shown, both the first connecting part 400 and the second connecting part 500 are used to connect to the valve housing 210.

[0043] like Figure 2 and Figure 4 As shown, the first connecting portion 400 includes a connecting protrusion 410 having an extension length in the length direction X, the width direction Y, and the height direction Z of the brake fluid container. Correspondingly, as... Figure 7 and Figure 8As shown, the valve housing 210 has a connecting groove 230 for accommodating the connecting protrusion 410. In some more specific embodiments, the connecting protrusion 410 is in line contact with the connecting groove 230.

[0044] With this configuration, when it is necessary to install the brake fluid container onto the top of the valve housing 210, such as Figure 9 As shown, simply push the connecting protrusion 410 into the connecting groove 230 of the valve housing 210 along direction P, and then rotate the brake fluid container around the connecting protrusion. Figure 9 Rotate clockwise so that the entire bottom surface of the brake fluid container rests on the top surface of the valve housing, as shown. Figure 10 As shown, the brake fluid container is then connected to the valve housing via a second connecting part located on the opposite side of the bottom surface relative to the first connecting part, thus achieving quick and convenient installation of the brake fluid container to the valve housing. Furthermore, this connection method does not require numerous connecting accessories, such as connecting pins or bolts, thus reducing its cost.

[0045] Furthermore, since the connecting protrusion 410 has a certain extension length in the length direction X, the width direction Y, and the height direction Z, it can provide a more stable connection load in all directions, thus making the connection more robust.

[0046] In some more specific implementations, such as Figure 3 and Figure 4 As shown, the extension length of the connecting protrusion 410 in the width direction Y of the brake fluid container is greater than its extension length in the length direction X and the height direction Z.

[0047] In some specific embodiments, the brake fluid container may be made of translucent plastic so that the user can observe the fluid level inside. In this case, the first connecting part extending from the bottom of the brake fluid container may also be made of plastic and integrally formed with the brake fluid container.

[0048] To further save materials and reduce weight, in some more specific embodiments, the interior of the connecting protrusion 410 may be hollow.

[0049] In some other implementations, the connecting bump can also be a hollow, cylindrical component.

[0050] Based on this, in order to ensure the strength of the hollow structure, such as Figure 4 As shown, a reinforcing rib 411 extending in the height direction Z can be provided inside the connecting protrusion. In some more specific embodiments, those skilled in the art can adjust the number of reinforcing ribs as needed.

[0051] Furthermore, in some specific implementation methods, such as Figure 4 As shown, a rib 412 may also be provided between the connecting protrusion 410 and the bottom surface. In some more specific embodiments, such as Figure 4 As shown, for the sake of manufacturing simplicity, each rib 412 and the corresponding reinforcing rib 411 can be located on the same straight line in the height direction.

[0052] In some embodiments, to further improve the ease of pushing the connecting protrusion into the connecting groove and to further improve the ease of rotating the brake fluid container around the connecting protrusion, such as Figure 4 As shown, at least one of the two ends of the connecting protrusion in the width direction Y of the brake fluid container has an arcuate portion 413, preferably, both ends have an arcuate portion 413.

[0053] like Figure 3 As shown, in some specific embodiments, in order to make it easier to push the connecting protrusion into the connecting groove, the bottom end of the connecting protrusion 410 in the height direction includes a wedge-shaped portion 414, which is a diagonal line along the outer contour line of the brake fluid container in the length direction, and the diagonal line slopes downward in the direction pointing to the second connecting portion.

[0054] In some specific implementation methods, such as Figure 3 As shown, the bottom surface 110 of the brake fluid container also has a downwardly extending overpressure protection protrusion 111, so that when the brake fluid container 100 is installed on the valve housing 210, there is a certain gap G between the bottom surface 110 and the top surface of the valve housing 210 (e.g., when the brake fluid container 100 is installed on the valve housing 210). Figure 10 (As shown), to prevent overpressure. In some more specific embodiments, multiple overpressure protection bumps may be provided.

[0055] like Figure 3 As shown, the bottom surface 110 of the brake fluid container has a connection port 120 for establishing a fluid connection with the valve housing. In some more specific embodiments, to further ensure the sealing effect at the connection port between the brake fluid container and the valve housing, such as... Figure 11 As shown, a sealing element 600 is also provided at the connection port. In some more specific embodiments, the sealing element 600 may be made of rubber.

[0056] In some specific implementation methods, such as Figure 2 and Figure 5 As shown, the first connecting part 400 is used to connect with the end face 201 of the valve housing 210 perpendicular to the length direction of the brake fluid container (i.e., a plane parallel to the X-axis and Y-axis), and the second connecting part 500 is used to connect with the side face 202 of the valve housing 210 parallel to the length direction of the brake fluid container (i.e., a plane parallel to the X-axis and Z-axis).

[0057] In some implementations, such as Figure 2 As shown, the bottom surface of the brake fluid container has a first side and a second side along the length direction X of the brake fluid container (i.e., Figure 2 (Left and right sides of the brake fluid container), wherein the first connecting part 400 is located on the first side and the second connecting part 500 is located on the second side. That is to say, the first connecting part and the second connecting part are basically located at both ends in the length direction of the bottom surface of the brake fluid container, which helps to further improve the stability of the connection.

[0058] Of course, in other embodiments, the second connecting portion may also be located in the middle of the length direction.

[0059] In some more specific implementations, considering the operating space, and to further improve the convenience of installation operations, such as... Figure 2 As shown, the first side with the first connecting portion is further away from the control lever 220 of the brake fluid system than the second side with the second connecting portion.

[0060] like Figure 11 As shown, in some specific embodiments, the second connecting portion 500 includes a connecting piece, on which a first connecting hole 501 is formed. Correspondingly, as... Figure 9 As shown, the valve housing 210 has a second connection hole 240 that corresponds to the first connection hole.

[0061] like Figure 10 As shown, when the brake fluid container is completely placed on top of the valve housing 210, the first connection hole 501 and the second connection hole 240 are aligned, and the connecting pin 700 passes through the first connection hole 501 and the second connection hole 240 to achieve the connection between the brake fluid container and the valve housing.

[0062] Figure 12 An exemplary connecting pin 700 is shown. In some more specific embodiments, the connecting pin may have a threaded portion 701, thereby threadedly connecting to a first connecting hole and / or a second connecting hole.

[0063] Therefore, this utility model can achieve convenient and stable installation of the brake fluid container and the valve assembly of the brake fluid system, and the operation process is simple and the manufacturing cost of the connection part is low.

[0064] In another embodiment, this invention also provides a vehicle having the brake fluid system described above. The brake fluid system is installed in the vehicle's engine compartment. Since this invention does not involve improvements to other parts of the vehicle, the vehicle will not be described in detail here.

[0065] Similarly, this utility model does not involve improvements to any part other than the connection structure between the valve body and the brake fluid container. Since the brake fluid system and valve assembly are known in the prior art, this utility model will not describe other parts of the brake fluid system and valve assembly in detail.

[0066] It should be noted that the prior art within the scope of protection of this utility model is not limited to the embodiments given in this utility model document. All prior art that does not contradict the solution of this utility model, including but not limited to prior patent documents, prior publications, prior public uses, etc., can be included in the scope of protection of this utility model.

All technical features described in this case can be freely combined or combined in any way, unless they contradict each other.

[0068] It should also be noted that the embodiments listed above are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments, and any similar changes or modifications made thereto that can be directly derived or easily conceived by those skilled in the art from the content disclosed in this utility model should fall within the protection scope of this utility model.
