DETAILED DESCRIPTION

[0040] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0041] In the present disclosure, unless otherwise stated, directional words such as "inside" and "outside" refer to the inside and outside of the contour of the corresponding component, wherein the inner wall of the cavity refers to the inner wall of the structure surrounding the cavity, and the outer wall of the cavity wall refers to the wall of the periphery of the cavity wall. "First" and "second" are used to distinguish one element from another and do not have order or importance.

[0042] Reference Figures 1 to 5As shown, the embodiment of the present disclosure provides a brake master cylinder assembly, including a main body 100 and a mounting channel 112 formed in the main body 100. The main body 100 includes a first area 110 and a second area 120. The first area 110 is formed with a first cavity 111 to accommodate a piston pump 2, and the second area 120 is formed with a second cavity 121 to accommodate a master cylinder piston (not shown in the figure). The first cavity 111 and the second cavity 121 are divided into two areas to avoid mutual interference between the two, and are formed on the same main body 100, so that the structure is compact and the integration is improved. The mounting channel 112 is used to accommodate at least part of the sensor assembly 200, such as the first section 211 of the first sensor 210 and the second sensor 220 described below. The sensor assembly 200 can be used to obtain the operating information of the master cylinder piston and / or the piston pump 2, that is, to obtain the working state in the first cavity 111 and / or the second cavity 121. The mounting channel 112 is disposed on the periphery of the cavity wall of the first cavity 111 . In other words, the sensor assembly 200 can be mounted on the periphery of the cavity wall of the first cavity 111 .

[0043] Through the above technical solution, the installation channel 112 for accommodating the sensor assembly 200 is arranged on the outer peripheral wall of the cavity wall of the first cavity 111, which can save the internal space of the cavity, facilitate the subsequent maintenance of the sensor assembly 200 or the piston pump 2 and the master cylinder piston in the cavity, and reduce the difficulty of assembly and maintenance. In addition, the installation channel 112 is located in the first cavity 111, which can effectively utilize the space around the first cavity 111, making the structure of the brake system more compact and integrated.

[0044] Reference Figure 3 and Figure 4 The extension direction of the installation channel 112 can be parallel to the extension direction of the first cavity 111, so that the installation channel 112 can be arranged more compactly in the first cavity 111, avoiding low space utilization caused by the skew between the two.

[0045] In the disclosed embodiment, the sensor assembly 200 may include multiple sensors and may realize multiple functions, such as being used to obtain the operating information of the piston pump 2 and / or the master cylinder piston. For example, it may include two sensors, one for obtaining the rotation speed information of the motor 20 of the piston pump 2, and the other for obtaining the displacement information of the master cylinder piston. The mounting channels 112 may also have multiple corresponding ones to accommodate multiple sensors. For example, in the case of two sensors, there may be two mounting channels 112, each of which may accommodate one sensor, so as to be spaced apart to prevent mutual interference. Among them, the multiple mounting channels 112 may be arranged in parallel with each other to make the layout design compact, reduce the overall volume of the brake master cylinder assembly, and improve the integration.

[0046] In the present disclosure, refer to Figure 3 The installation channel 112 can be located in the first area 110 so that the installation channel 112 does not occupy the second area 120 to avoid components near the second area 120, such as hydraulic components or liquid supply components, etc., to avoid interference and improve the space utilization of the first area 110.

[0047] The master cylinder assembly may include a wire passage 113, which may be used for passing a wire harness 21 of the piston pump 2, and the wire harness 21 may be a three-phase wire of the motor 20 of the piston pump 2. Figure 3 As shown, the wire passage 113 can be located in the first area 110. Since the first cavity 111 for accommodating the piston pump 2 is located in the first area 110, the wire passage 113 is located in the first area 110, so that the distance of the wire harness 21 can be shortened as much as possible. In addition, the wire passage 112 can also be made not to occupy the second area 120, so as to avoid components near the second area 120, such as hydraulic components or liquid supply components, etc., to avoid interference, and improve the space utilization of the first area 110.

[0048] Combination Figure 2 and Figure 3 The installation channel 112 and the wire passage 113 can be arranged around the circumference of the first cavity 111, so that the installation channel 112 and the wire passage 113 are compactly arranged on the circumference of the first cavity 111, avoiding occupying a large space in a single direction and making the structure uniform.

[0049] Among them, the extension direction of the installation channel 112 and the wire passage channel 113 can be parallel to the extension direction of the first cavity 111, so that the installation channel 112 and the wire passage channel 113 can be arranged more compactly with the first cavity 111 to avoid low space utilization caused by the skew between the two.

[0050] According to an implementation of the embodiment of the present disclosure, the sensor assembly 200 may include a first sensor 210, and the first sensor 210 is used to obtain the operation information of the master cylinder piston. For example, the first sensor 210 may be a displacement sensor to obtain the position displacement information of the master cylinder piston in the second cavity 121. A transmitter of the displacement sensor may be provided on the master cylinder piston, and a receiver of the sensor is accommodated in the mounting channel 112, where the first sensor 210 refers to the receiver. The first sensor 210 may extend from the first area 110 to the second area 120 to be close to the second cavity 121 to accurately obtain the displacement information of the master cylinder piston in the second cavity 121. The mounting channel 112 of the first sensor 210 may be arranged closer to the second area 120 than other parts of the structure, so that it is easier to approach the second cavity 121. The first sensor 210 may extend to the second area 120 in the area of ​​the outer peripheral wall of the first cavity 111 and parallel to the first cavity 111, and a cavity is opened in the area extending into the interior of the main body 100 for the first sensor 210 to approach the master cylinder piston. Of course, it is understandable that the installation channel 112 of the first sensor 210 may also be arranged on the outer peripheral wall of the first cavity 111 to extend obliquely from the first area 110 to the second area 120 .

[0051] In the embodiment of the present disclosure, the first sensor 210 can be configured to extend to the outer wall of the second cavity 121. In this way, the first sensor 210 and the sensor transmitter installed inside the second cavity 121 can be separated only by the cavity wall of the second cavity 121 without any other structure, thereby ensuring the accuracy of detection.

[0052] In one embodiment, if Figure 5 As shown, the first sensor 210 may include a first section 211 and a second section 212, the first section 211 may extend in the same direction as the first cavity 111 along the outer wall of the cavity wall of the first cavity 111, and the second section 212 may extend from one end of the first section 211 close to the second cavity 121 to the outer wall of the cavity wall of the second cavity 121. The first sensor 210 is provided in two sections so that it can extend to the outer wall of the second cavity 121, thereby being close to the transmitter in the second cavity 121.

[0053] Reference Figure 5 The first sensor 210 may further include a third section 213, which may extend from one end of the second section 212 close to the second cavity 121 along the outer wall of the cavity wall of the second cavity 121, so as to be kept on the outer wall of the cavity wall of the second cavity 121, thereby ensuring its detection accuracy. The portion of the outer wall of the cavity wall of the second cavity 121 for setting the third section 213 may be constructed as a flat surface, so as to facilitate the stable setting of the third section 213, and the third section 213 may also be set on the outer wall through a fixing structure.

[0054] In the disclosed embodiment, the transmitter of the first sensor 210 can be arranged along the second direction, and the installation direction of the first sensor 210 can be perpendicular to the installation direction of the transmitter, so that the detection structure can be arranged in different directions, avoiding the large space occupied by arrangement in one direction, making the structure of the brake master cylinder assembly compact and improving the integration.

[0055] According to an embodiment of the present disclosure, referring to Figure 4 As shown, the sensor assembly 200 may include a second sensor 220, and the second sensor 220 is used to obtain the operation information of the piston pump 2. For example, the second sensor 220 may be a rotation speed sensor, which is used to obtain the rotation speed of the motor 20 of the piston pump 2. One end of the main body 100 is used to connect to the motor housing 22 of the motor 20, and the second sensor 220 may extend to one end of the main body 100 used to connect to the motor housing 22 of the piston pump 2, so as to be close to the motor 20 in the motor housing 22.

[0056] An end of the main body 100 for connecting to the motor housing 22 may be formed with an opening structure 101, and the second sensor 220 may extend to the opening structure 101, and the opening structure 101 is used to communicate with the motor housing 22. A Hall magnetic ring may be provided on the rotor of the motor 20 in the motor housing 22, and the second sensor 220 is extended to the opening structure 101 communicated with the motor housing 22, so that the second sensor 220 and the Hall magnetic ring 23 are not blocked, thereby obtaining the speed information of the motor 20 through the change of the magnetic field.

[0057] In one embodiment of the present disclosure, the extension direction of the first cavity 111 is perpendicular to the extension direction of the second cavity 121. The vertical arrangement can facilitate the integration of the braking system and the arrangement of other components such as hydraulic components.

[0058] Combination Figures 1 to 5 , the first cavity 111 can extend along the first direction, the second cavity 121 can extend along the second direction, the first area 110 can be located on one side of the second area 120 along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. This vertical arrangement can make the layout more compact and regular, and facilitate the connection of the brake master cylinder assembly with other structures. For example, the motor housing 22 can be connected to one side of the brake master cylinder assembly along the first direction, the hydraulic assembly described below can be connected to one side of the brake master cylinder assembly along the first direction and arranged opposite to the motor housing 22, and the fluid supply assembly can be arranged on one side of the brake master cylinder assembly along the third direction, such as on the side of the second area 120 facing away from the first area 110.

[0059] The brake system includes a hydraulic component, which is connected to the brake master cylinder assembly. Figure 1 and Figure 3 A hydraulic connection surface 102 may be formed on the main body 100 for connecting the hydraulic assembly, and the hydraulic connection surface 102 occupies part of the first area 110 and part of the second area 120. The hydraulic assembly is used to communicate with the first cavity 111 located in the first area 110 and the second cavity 121 located in the second area 120. The hydraulic connection surface of the hydraulic assembly is arranged in the part occupying the two areas to facilitate its communication with the corresponding cavity and shorten the communication path.

[0060] The hydraulic connection surface 102 may be configured to be parallel to the extension direction of the second cavity 121 and perpendicular to the extension direction of the first cavity 111. Figure 3 In the illustrated embodiment, the hydraulic connection surface 102 is within a plane communicating with the second direction and the third direction, and can be installed in a vacant position between the first area 110 and the second area 120 , so that the layout is compact and the integration is high.

[0061] The second region 120 includes a plurality of liquid outlet channels 114 arranged corresponding to the hydraulic connection surface 102 to connect the interior of the main body 100 with the hydraulic assembly, and the liquid outlet channels 114 are configured to be perpendicular to the extension direction of the second cavity 121 and parallel to the extension direction of the first cavity 111. The end surface of the liquid outlet of the liquid outlet channel 114 constitutes the hydraulic connection surface 102, so that the hydraulic connection surface 102 can present the arrangement orientation as described above.

[0062] A hydraulic pipeline is formed inside the main body 100, the liquid outlet channel 114 is connected to the hydraulic pipeline, and the hydraulic pipeline is connected to the second cavity 121 and the first cavity 111 respectively, so as to realize the communication between the first cavity 111 and the second cavity 121 and the hydraulic component through the hydraulic pipeline.

[0063] The first area 110 includes a wire passage 113 arranged corresponding to the hydraulic connection surface 102, for allowing the wiring harness 21 of the piston pump 2 to pass through. The end face of the wire passage 113 can be flush with the end face of at least part of the liquid outlet channel 114, so that the end face of the wire passage 113 can form a smooth hydraulic connection surface 102 together with the end face of the liquid outlet channel 114, thereby preventing the wire passage 113 from affecting the layout of the hydraulic components.

[0064] Reference Figure 1 and Figure 3 At least a portion of the outer wall of the first cavity 111 is formed with an avoidance surface 115 for avoiding the hydraulic component, so that the hydraulic component can have sufficient installation space for installation.

[0065] The avoidance surface 115 can be configured to match the outer contour of the hydraulic assembly, so that the avoidance surface 115 can be arranged in close contact with the hydraulic assembly to improve space utilization. In the disclosed embodiment, the outer contour of the hydraulic assembly is configured as a screen, and at least part of the avoidance surface 115 can be configured as a plane to match the outer contour of the hydraulic assembly.

[0066] Reference Figure 1 and Figure 3 The second area 120 may be provided with a liquid supply connection surface 103 for connecting a liquid supply component, such as an oil pot. The liquid supply component is arranged in the second area 120 to be separated from the installation channel 112 and the wire passage 113 to avoid interference between them.

[0067] The liquid supply connection surface 103 is constructed to be parallel to the extension direction of the second cavity 121 and parallel to the extension direction along the first cavity 111, so as to be set on a different side from the hydraulic connection surface 103, and various components are arranged in various directions to avoid excessive size in a single direction.

[0068] Reference Figure 1 and Figure 3 The second area 120 includes a liquid inlet channel 116 corresponding to the liquid supply connection surface 103 to connect the interior of the main body 100 with the liquid supply assembly, and the liquid inlet channel 116 is configured to be perpendicular to the extension direction of the second cavity 121 and perpendicular to the extension direction of the first cavity 111. The end surface at the orifice of the liquid inlet channel 116 constitutes the liquid supply connection surface 103, so that the liquid supply connection surface 103 can present the arrangement orientation described above.

[0069] A hydraulic pipeline is formed inside the main body 100, the liquid inlet channel 116 is connected to the hydraulic pipeline, and the hydraulic pipeline is connected to the second cavity 121 and the first cavity 111 respectively, so that the liquid supply component is connected to the first cavity 111 and the second cavity 121 through the hydraulic pipeline.
