[0028] References to "embodiments" in this specification mean that particular features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive of other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0029] The brake fluid reservoir is an essential component of the hydraulic braking system of passenger cars. Due to the limitations of the production line filling equipment and the requirements for pedestrian protection against collision in terms of dimensions, the length of the inlet pipe of the brake fluid reservoir needs to be adjusted according to different vehicle models. The conventional solution for the brake fluid reservoir is that the length of its inlet pipe is fixed and non-adjustable, and the brake fluid reservoirs of different vehicle models cannot be made universal. For different vehicle models, new structures of the brake fluid reservoir need to be developed, so new matching, selection, and development are required, which results in a long cycle and high costs.

[0030] In view of this, the present application provides a brake fluid reservoir, which includes a reservoir body, a connecting pipe, a spout, and an adjusting ring. The connecting pipe, the adjusting ring, and the spout together form the inlet pipe of the brake fluid reservoir. The adjusting ring is fastened to the connecting pipe through the spout. Different lengths of adjusting rings can be selected according to different vehicle models. Therefore, only by selecting the corresponding length of the adjusting ring according to different vehicle models, the adjustment of the length of the inlet pipe of the brake fluid reservoir can be achieved, so as to make the brake fluid reservoir universal for different vehicle models, improve the generalization rate of the brake fluid reservoir among different vehicle models, and reduce the development cycle and cost. The structure, principle, and function of the brake fluid reservoir of the present application will be described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figure 1 , Figure 1 which is a three-dimensional structural schematic diagram of an embodiment of the brake fluid reservoir provided by the present application, Figure 2 is Figure 1 the exploded structural schematic diagram of the brake fluid reservoir of Figure 3 is Figure 1 the front view of the brake fluid reservoir of Figure 4 is Figure 3 the A-A sectional view of

[0032] The brake fluid reservoir 10 includes a reservoir body 110, a connecting pipe 120, a spout 500, and an adjusting ring 400.

[0033] Combined with Figure 5 , Figure 5 is Figure 2Schematic three-dimensional structure diagram of the liquid reservoir body 110 and the connecting pipe 120 in the brake fluid reservoir 10. The reservoir body 110 is the main structure of the brake fluid reservoir 10 for storing brake fluid. The reservoir body 110 is provided with a liquid inlet end 111, and the brake fluid is injected into the reservoir body 110 through the liquid inlet end 111. The connecting pipe 120 is connected to the liquid inlet end 111. The connecting pipe 120 and the reservoir body 110 can be a split structure or an integral structure. Further, the connecting pipe 120 and the reservoir body 110 are integrally formed. Figures 1 to 5 Shows a structure in which the connecting pipe 120 and the reservoir body 110 are integrally formed. The connecting pipe 120 is used to facilitate the connection of the spout 500 and the adjusting ring 400 relative to the reservoir body 110.

[0034] Combined with Figure 6 , Figure 6 is Figure 2 Schematic three-dimensional structure diagram of the spout 500 in the brake fluid reservoir 10. The spout 500 includes a mounting ring portion 510 and a limiting ring portion 520. The mounting ring portion 510 and the limiting ring portion 520 are arranged along the axis of the spout 500. The mounting ring portion 510 is sleeved outside the connecting pipe 120, and the limiting ring portion 520 is located on one side of the connecting pipe 120 in the axial direction. Specifically, the limiting ring portion 520 is located on the side of the connecting pipe 120 axially away from the reservoir body 110, and the limiting ring portion 520 and the connecting pipe 120 are arranged at intervals along the axial direction of the connecting pipe 120 to install the adjusting ring 400 between the limiting ring portion 520 and the connecting pipe 120. More specifically, the inner diameter of the limiting ring portion 520 of the spout 500 is smaller than the inner diameter of the mounting ring portion 510 to form a lapping platform 521 on the end face of the limiting ring portion 520 facing the mounting ring portion 510. The lapping platform 521 is used for axially limiting and supporting the adjusting ring 400.

[0035] The adjusting ring 400 is located radially inside the mounting ring portion 510 and is clamped between the connecting pipe 120 and the limiting ring portion 520 in the axial direction of the connecting pipe 120. Specifically, the adjusting ring 400 is clamped between the connecting pipe 120 and the lapping platform 521 in the axial direction of the connecting pipe 120 to realize the fastening of the adjusting ring 400 relative to the connecting pipe 120.

[0036] In this application, the liquid inlet pipe of the brake fluid reservoir 10 includes the connecting pipe 120, the spout 500 and the adjusting ring 400. The adjusting ring 400 is fastened to the connecting pipe 120 through the spout 500, and adjusting rings 400 of different lengths can be selected according to different vehicle models (please refer to Figure 7 , Figure 7Figures (a)-(c) show the structures of the adjustment rings 400 with different heights. Therefore, only by selecting the adjustment rings 400 with corresponding lengths according to different vehicle models, the length of the liquid inlet pipe of the brake fluid reservoir 10 can be adjusted, so as to make the brake fluid reservoir 10 universal for different vehicle models, improve the generalization rate of the brake fluid reservoir 10 in different vehicle models, and reduce the development cycle and cost.

[0037] The brake fluid reservoir 10 of the present application can realize liquid inlet through the spout 500, the adjustment ring 400 and the connecting pipe 120. Generally speaking, the brake fluid reservoir 10 may further include a liquid outlet pipe 130. The liquid inlet pipe (including the connecting pipe 120, the spout 500 and the adjustment ring 400) and the liquid outlet pipe 130 of the brake fluid reservoir 10 are respectively located on opposite sides of the reservoir body 110, and the brake fluid in the brake fluid reservoir 10 can be discharged through the liquid outlet pipe 130.

[0038] Refer to again Figures 1 to 4 , in one embodiment, the brake fluid reservoir 10 further includes a fastening ring 200. Combining Figure 8 , Figure 8 is Figure 2 a three-dimensional structural schematic diagram of the fastening ring 200 in the brake fluid reservoir 10. The fastening ring 200 includes a first ring portion 210 and a second ring portion 220 arranged along its axial direction. The first ring portion 210 is sleeved and fastened outside the connecting pipe 120. An installation ring cavity is formed between the second ring portion 220 and the outer side wall of the connecting pipe 120. The installation ring portion 510 of the spout 500 is inserted into the installation ring cavity and is limited by the axial end of the first ring portion 210. The second ring portion 220 is fastened to the installation ring portion 510, so as to fasten the spout 500 to the connecting pipe 120, and further fasten the adjustment ring 400 to the connecting pipe 120. The first ring portion 210 and the second ring portion 220 can be integrally formed to increase the sealing performance. In this embodiment, the spout 500 is connected to the connecting pipe 120 through the fastening ring 200, and the connection area between the installation ring portion 510 of the spout 500 and the connecting pipe 120 can be wrapped by the fastening ring 200, which increases the connection sealing performance between the installation ring portion 510 of the spout 500 and the connecting pipe 120. In this embodiment, there is no limit to the height of the second ring portion 220 covering the installation ring portion 510 in the axial direction. Figure 4 shows the situation where the axial distance between the second ring portion 220 and the limiting ring portion 520 is less than the axial distance between the connecting pipe 120 and the limiting ring portion 520. In other embodiments, the axial distance between the second ring portion 220 and the limiting ring portion 520 may also be greater than or equal to the axial distance between the connecting pipe 120 and the limiting ring portion 520.

[0039] Further, please refer to together Figure 4 , Figure 6 and Figure 8, in one embodiment, the inner sidewall of the first ring portion 210 is provided with a first fastening ring internal thread 211, combined with Figure 4 and Figure 5 , on the outer sidewall of the connecting pipe 120 corresponding to the area of the first ring portion 210, an external thread 121 of the connecting pipe is provided. The locking between the fastening ring 200 and the connecting pipe 120 is achieved through the thread fitting of the first fastening ring internal thread 211 and the external thread 121 of the connecting pipe. In this embodiment, the fastening between the fastening ring 200 and the connecting pipe 120 can be realized through the thread fitting between the first ring portion 210 of the fastening ring 200 and the connecting pipe 120. By screwing the spout 500, the fastening between the fastening ring 200 and the spout 500 can be achieved. The operation is convenient and fast, and the thread connection can also increase the connection tightness between the first ring portion 210 of the fastening ring 200 and the connecting pipe 120 to a certain extent.

[0040] Furthermore, please refer to Figure 4 , Figure 6 and Figure 8 , in one embodiment, the inner sidewall of the second ring portion 220 is provided with a second fastening ring internal thread 221, and on the outer sidewall of the mounting ring portion 510 of the spout 500, a first spout external thread 501 is provided. The locking between the second ring portion 220 of the fastening ring 200 and the spout 500 is achieved through the thread fitting of the second fastening ring internal thread 221 and the first spout external thread 501. In this embodiment, the locking between the fastening ring 200 and the spout 500 can be realized through the thread fitting between the second ring portion 220 of the fastening ring 200 and the mounting ring portion 510 of the spout 500. The fastening between the fastening ring 200 and the spout 500 can be achieved by keeping the spout 500 stationary and screwing the fastening ring 200, or by keeping the fastening ring 200 stationary and screwing the spout 500. The operation is convenient and fast, and the thread connection can also increase the connection tightness between the fastening ring 200 and the spout 500 to a certain extent. The present application does not limit the installation sequence of the fastening ring 200, the adjusting ring 400, and the spout 500.

[0042] Based on the above embodiments, referring to Figure 2 and Figure 4, the brake fluid reservoir 10 of the embodiment of the present application further includes a first seal 310. The first seal 310 is sealingly connected between the end faces of the connecting pipe 120 and the adjusting ring 400 that face each other. The first seal 310 can be an elastic ring-shaped seal. The first seal 310 is used for end face sealing between the adjusting ring 400 and the connecting pipe 120 to prevent the brake fluid in the reservoir body 110 from leaking to the outside of the brake fluid reservoir 10 through the gap between the adjusting ring 400 and the connecting pipe 120. Specifically, please refer to Figure 4 , Figure 5 and Figure 7 , on the end face of the connecting pipe 120 facing the adjusting ring 400, there is a first mounting groove first half groove 122. Correspondingly, on the end face of the adjusting ring 400 facing the connecting pipe 120, there is a first mounting groove second half groove 401.
