[0018] Figure 2 schematically shows the brake fluid reservoir according to one embodiment of the present application; Figure 1 schematically shows the brake fluid reservoir according to one embodiment of the present application;

[0020] Embodiments of the present application will be described in detail below with reference to the drawings. Those skilled in the art will appreciate that the description is merely descriptive, exemplary and should not be construed as limiting the scope of protection of the present application.

[0021] Firstly, the coordinate system established herein is described. The origin O of the coordinate system coincides with the center of mass of the vehicle, and XOZ is in the plane of symmetry of the vehicle. When the vehicle is running on a horizontal road surface, the X axis is parallel to the ground and points forward, the Y axis points to the left of the driver, and the Z axis points upward through the center of mass. "Up and down" defines the relative position in the direction of the Z axis,

[0022] "Up" is located in the positive direction of the Z axis relative to "down".

[0023] Referring to Figures 1 to 3 As shown in the figure, the brake fluid reservoir 100 according to one embodiment of the present application comprises a reservoir body 10 and a cover 20. The reservoir body 10 comprises a neck 13 surrounding an opening 14 of the reservoir body 10, and the cover 20 is used to close the opening 14. Brake fluid can enter or exit the brake fluid reservoir 100 through the opening 14. There is only one first limiting portion 11 in the neck 13, and there is only one first positioning portion 21 in the cover 20. The first limiting portion 11 and the first positioning portion 21 cooperate to limit the position of the cover 20 relative to the neck 13 in a first direction. In the installed state, the first limiting portion 11 cooperates with the first positioning portion 21, the cover 20 is installed on the neck 13 and thus on the brake fluid reservoir 100, which is installed on the vehicle body, for example, through a mounting bracket.

[0024] In the technical solution according to the present application, by providing only one first limiting portion 11 in the neck 13 and only one first positioning portion 21 in the cover 20, the position of the cover 20 relative to the neck 13 can be uniquely determined. In the installed state, since the position of the reservoir body 10 and its neck 13 relative to the vehicle body is determined, the position of the cover 20 relative to the vehicle body is also determined, so that no matter what the initial angle of the cover 20 is, after installation is completed, the cover 20 always presents a predetermined and determined angle relative to the vehicle body, thereby meeting the visual or functional requirements of the cover 20.

[0025] Referring to Figure 1 ​As shown, an identification 23 is provided on the outer surface of the cover 20, the relative position of which to the first positioning portion 21 is set in advance, and the identification is identifiable when the first limiting portion 11 cooperates with the first positioning portion 21. One possible solution is to provide an identification on the outer surface of the cover 20 perpendicular to the XY plane, which is directed towards an observer outside the vehicle and thus visible and identifiable only in the installed state. Another possible solution is to provide an identification on the outer surface of the cover 20 parallel to the XY plane, which has different meanings when viewed in different directions or is easily identifiable only when viewed in a predetermined direction, which directly expresses the meaning intended by the designer for an observer outside the vehicle in the installed state.

[0026] In one embodiment, the first positioning portion 21 can be configured as a positioning block, and the first limiting portion 11 can be configured as a limiting block capable of abutting against the positioning block to limit the position of the cover 20 relative to the neck portion 13. Additionally, the limiting block and the positioning block can be rigidly configured such that, when the limiting block abuts against the positioning block, no relative movement between the limiting block and the positioning block can occur; or the limiting block and / or the positioning block can be elastically configured such that, when the limiting block abuts against the positioning block, if an external force is applied to break a certain threshold, relative movement between the limiting block and the positioning block can still occur.

[0027] Further, a buckle can be provided in one of the limiting block and the positioning block, and a slot cooperating with the buckle can be provided in the other, the buckle being capable of extending into the slot and cooperating with each other, and when the buckle cooperates with the slot, the cover 20 is fixed relative to the neck portion 13.

[0028] Further, the opening 14 of the liquid storage tank body 10 is configured as a circle. The inner surface of the cover 20 is configured as a circle, and correspondingly, the outer surface of the neck portion 13 is also configured as a circle. In the installed state, the inner surface of the cover 20 at least partially surrounds the outer surface of the neck portion 13. For example, the cover 20 is installed to the neck portion 13 by rotating it in the first direction. In an embodiment not shown, it can also be provided that, in the installed state, the inner surface of the neck portion 13 at least partially surrounds the outer surface of the cover 20.

[0029] In the embodiment shown in FIGS. 1 and 2, the first positioning portion 21 is configured on the outer surface of the cover 20, and the first limiting portion 11 is configured on the inner surface of the neck portion 13, and the first positioning portion 21 cooperates with the first limiting portion 11 to limit the rotation of the cover 20 relative to the neck portion 13 in the first direction. Figure 2 and Figure 3 In the embodiment shown in FIGS. 1 and 2, the first positioning portion 21 is configured on the outer surface of the cover 20, and the first limiting portion 11 is configured on the inner surface of the neck portion 13, and the first positioning portion 21 cooperates with the first limiting portion 11 to limit the rotation of the cover 20 relative to the neck portion 13 in the first direction.Figure 2 As shown, a retaining ring 15 is provided on the outer surface of the neck portion 13, which is used to be positioned with a clamp when the brake fluid is filled into the brake fluid reservoir 100.

[0030] Further, a second limiting portion 12 is provided on the outer surface of the neck portion 13, and a second positioning portion 22 is provided on the inner surface of the cover 20, which are used to limit the position of the cover 20 relative to the neck portion 13 in a second direction.

[0031] In the embodiment shown in the figure, the first positioning portion 21 is located below the second positioning portion 22, and correspondingly, the first limiting portion 11 is located below the second limiting portion 12. In an embodiment not shown in the figure, the first positioning portion 21 can also be located above the second positioning portion 22, and correspondingly, the first limiting portion 11 is located above the second limiting portion 12.

[0032] In the second direction, a film is further provided between the cover 20 and the neck portion 13, which is used to seal the opening 14 surrounded by the neck portion 13, so as to reduce the contact area of the brake fluid in the brake fluid reservoir 100 with air, and keep the performance of the brake fluid stable. In the second direction, on the one hand, the cover 20 abuts against the film and the film abuts against the neck portion 13, thereby limiting the position of the cover 20 relative to the neck portion 13 from above; on the other hand, the second limiting portion 12 abuts against the second positioning portion 22, thereby limiting the position of the cover 20 relative to the neck portion 13 from below.

[0033] The second direction is, for example, perpendicular to the first direction. The first direction can be the rotation direction of the cover 20 relative to the neck portion 13, and the second direction can be the direction perpendicular to the rotation direction of the cover 20 relative to the neck portion 13. For example, in the state where the brake fluid reservoir 100 is installed, the first direction is substantially parallel to the XY plane, and the second direction is substantially parallel to the Z axis.

[0034] It is possible that at least two second limiting portions 12 are provided on the outer surface of the neck portion 13, for example, 2, 3, 4 or 5 second limiting portions 12. Figure 2The cover 20 has three second limiting portions. The number of these second limiting portions 12 needs to consider the impact on the movement of the cover 20 relative to the neck 13 in the second direction, such as changing the frictional force. The at least two second limiting portions 12 are evenly distributed circumferentially around the neck 13, with gaps between adjacent second limiting portions, through which the first positioning portion 21 and the second positioning portion 22 of the cover 20 can move. Since each second limiting portion 12 is the same size, the gaps are also the same size. Therefore, the cover 20 can easily and quickly pass through the gaps, facilitating its installation onto the neck 13.

[0035] The second limiting portion 12 includes a guide portion 121, which cooperates with the second positioning portion 22 to guide the movement of the cover 20 relative to the neck 13 in a first direction. For example, the guide portion 121 is arranged obliquely in the first direction, and the cover 20 moves relative to the neck 13 in the first direction due to the guidance of the guide portion 121, while the guide portion 121 applies a generally downward force to the cover 20, causing the cover 20 to move downward. The membrane between the cover 20 and the neck 13 can be elastically constructed, and when the cover 20 moves downward due to the guide portion 121, the membrane is compressed and thus applies an upward reaction force to the cover 20, thereby generating a frictional force between the guide portion 121 and the second positioning portion 22, which tends to resist the movement of the cover 20 relative to the neck 13 in the first direction.

[0036] The second limiting part 12 further includes a jumping part 122, which is arranged in front of the guide part 121 in a first direction. After moving along the guide part 121, the second positioning part 22 moves discontinuously into the jumping part 122. The jumping part 122 extends discontinuously from the guide part 121. When the second positioning part 22 continues to move along the guide part 121 into the jumping part 122, a perceptible jump occurs, such as generating sound or vibration feedback, which can be perceived by the operator. For example, the jumping part 122 is constructed as a recessed structure, and the jumping part 122 is arranged above the adjacent guide part 121. Under the operation of the operator, the cover 20 continues to move forward from the guide part 121 in the first direction. Under the elasticity of the membrane, the second positioning part 22 moves upward and enters the jumping part 122.

[0037] It is feasible to pre-set relative positions of the jump portion 122, the second positioning portion 22, the first limiting portion 11 and the first positioning portion 21, so that the first limiting portion 11 limits the position of the first positioning portion 21 when or after the second positioning portion 22 moves into the jump portion 122. For example, when the second positioning portion 22 moves into the jump portion 122, the operator obtains feedback and stops operating the cover 20, at this time the first limiting portion 11 abuts against the first positioning portion 21 to limit the position of the first positioning portion 21, and the installation of the cover 20 is completed. The jump portion 122 can include a blocking portion for limiting the forward and / or backward movement of the second positioning portion 22 in the first direction.

[0038] In the case where at least two second limiting portions 12 are arranged on the outer surface of the neck portion 13, the jump portion 122 can be arranged at one or more of the at least two second limiting portions 12.

[0039] The application also includes an automobile with the brake fluid reservoir of any one or more of the above-mentioned embodiments, which has the technical features and effects corresponding to the above description, and thus will not be described here again.
