DETAILED DESCRIPTION

[0049] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0050] In the description of the present application, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly specified.

[0051] The following will be described in detail Figures 1-10 The brake assembly 10 according to an embodiment of the present application and the vehicle 100 having the same are described in detail below.

[0052] Referring to Figures 1-3 , Figures 7-9 As shown in FIG. 1, according to the brake assembly 10 of the embodiment of the present application, the brake assembly 10 comprises a hydraulic unit 1, a pressure building module and a control unit 3, the hydraulic unit 1 forms an accommodation space 14, the pressure building module comprises a motor 21, the motor 21 is at least partially arranged in the accommodation space 14, the pressure building module is used for pressurizing the liquid in the hydraulic unit 1, the control unit 3 is arranged outside the accommodation space 14, and the pressure building module is connected with the control unit 3.

[0053] Specifically, the motor 21 is at least partially arranged in the accommodation space 14, which effectively reduces the occupied space of the brake assembly 10 as a whole, avoids the waste of space caused by unreasonable arrangement of various components (such as the motor 21, the drive pump 22, the brake master cylinder, etc.) in the brake assembly 10, and helps to improve the compactness and layout rationality of the structure of the brake assembly 10.

[0054] The accommodation space 14 can be formed by recessing the hydraulic unit 1, for example, in the example shown in FIG. 1, the hydraulic unit 1 is configured in an L shape, and the space surrounded by the L-shaped hydraulic unit 1 is formed as the accommodation space 14. Figure 1 In the related art, the pressure building module and the control unit are both arranged on the side surface of the hydraulic unit, but the pressure building module has a large volume, and placing the pressure building module on one side of the hydraulic unit or setting a recess (3-5 mm deep) for installing the pressure building module still cannot effectively reduce the influence of the volume of the pressure building module.

[0055] According to the brake assembly 10 of the embodiment of the present application, by arranging the motor 21 at least partially in the accommodation space 14 of the hydraulic unit 1, the hydraulic unit 1 and the pressure building module are highly integrated, the space occupied by the brake assembly 10 is reduced, and the structure of the brake assembly 10 is compact.

[0056] The following is described by taking that the brake assembly 10 can be applied to the brake system of a vehicle 100 as an example, and it should be noted that the brake assembly can also be applied to the brake system of other equipment, which is not described here in detail.

[0057] In some embodiments of the present application, referring to FIG. 2, the hydraulic unit 1 comprises a first liquid path block 11 and a second liquid path block 12, the pressure building module is at least used for pressurizing the liquid in the first liquid path block 11, the second liquid path block 12 is installed on the first liquid path block 11, the flow path in the first liquid path block 11 is in communication with the flow path in the second liquid path block 12, and the first liquid path block 11 is connected with the second liquid path block 12 to form the accommodation space 14.

[0058] Figures 1-3

[0059] ​​Specifically, the first liquid path block 11 can be connected to the wheel end, and the pressure building module pressurizes the first liquid path block 11 to ensure that the hydraulic pressure flowing to the wheel end has sufficient pressure and stability, so that the wheel end can quickly respond when braking, generate strong and stable braking force, effectively shorten the braking distance, and improve the braking safety. The second liquid path block 12 is installed on the first liquid path block 11, and the two are tightly combined to enhance the overall structural strength of the hydraulic unit 1, so that the hydraulic unit 1 can better withstand the high pressure and impact force generated during braking, reduce the risk of component damage caused by vibration or pressure fluctuations, and improve the reliability and durability of the brake assembly 10.

[0060] In some embodiments of the present application, referring to Figures 1-4 、 Figures 7-9 , the control unit 3 is installed on one side of the first liquid path block 11, and the motor 21 is located on the other side of the first liquid path block 11. The motor 21 is arranged in the accommodation space 14. Specifically, the control unit 3 and the motor 21 are respectively located on both sides of the first liquid path block 11, and the motor 21 is arranged in the accommodation space 14, which makes full use of the limited space, makes the brake assembly 10 compact in structure, avoids interference between components, and is beneficial to integration in the limited space of the vehicle 100. At the same time, the control unit 3 and the motor 21 are respectively located on both sides of the first liquid path block 11, which can reduce the influence of electromagnetic interference generated by the operation of the motor 21 on the signal transmission of the control unit 3, ensure the stability of the control signal, and improve the stability and reliability of the brake system.

[0061] In some embodiments of the present application, referring to Figures 1-4 、 Figures 7-9 , the second liquid path block 12 and the motor 21 are located on the same side of the first liquid path block 11. Thus, the second liquid path block 12 and the motor 21 are arranged on the same side of the first liquid path block 11, and the motor 21 is arranged in the space formed by the lower side of the second liquid path block 12 and the left side of the first liquid path block 11, which can greatly optimize the space structure of the brake assembly 10, effectively utilize the limited installation space in the brake assembly 10, avoid space waste caused by the dispersion of components, make the integration of the entire brake assembly 10 higher, and leave more space for the arrangement of other devices or components, which helps to improve the rationality and compactness of the overall layout of the brake assembly 10.

[0062] In some embodiments of the present application, referring to Figures 1-4 、 Figures 7-9As shown in FIG. 1, the motor 21 is mounted on the second liquid passage block 12. In this way, this mounting manner further optimizes the spatial layout of the brake assembly 10, and mounting the motor 21 on the second liquid passage block 12 reduces the requirement for independent mounting space, so that the entire brake assembly 10 is more compact in structure. In a vehicle 100 or other equipment with limited space and strict layout requirements, this compact design can better utilize the limited space and provide more possibilities for the arrangement of other components, which is conducive to improving the rationality and compactness of the overall structure of the vehicle 100.

[0063] In some embodiments of the present application, referring to Figures 1-3 、 Figure 5 、 Figures 7-9 As shown in FIG. 1, the brake assembly 10 further comprises a support 4, which is mounted on the second liquid passage block 12, and the motor 21 is mounted on the support 4, i.e., the motor 21 is mounted on the second liquid passage block 12 through the support 4. Specifically, the support 4 is mounted on the second liquid passage block 12, and the motor 21 is mounted on the support 4, forming a stable support structure, so that the vibration and impact force generated by the motor 21 during operation can be evenly dispersed to the second liquid passage block 12 through the support 4, reducing the influence of the vibration of the motor 21 on other components of the brake assembly 10, enhancing the stability and reliability of the entire brake assembly 10, and reducing the risk of damage to each component. In addition, by providing the support 4, the arrangement position of the motor 21 relative to the second liquid passage block 12 can be more flexible.

[0064] The motor 21 and the support 4 can be arranged in the accommodation space 14, so as to fully utilize the accommodation space 14 without occupying other external space.

[0065] Optionally, the connection manner of the support 4 and the second liquid passage block 12 can be a threaded fastener connection, a rivet connection, a buckle connection, etc. For example Figure 1 As shown in FIG. 1, the connection manner of the support 4 and the second liquid passage block 12 is a threaded fastener connection.

[0066] Optionally, the connection manner of the motor 21 and the support 4 can be a threaded fastener connection, a rivet connection, a buckle connection, etc. For example Figure 1 As shown in FIG. 1, the connection manner of the motor 21 and the support 4 is a threaded fastener connection.

[0067] In some embodiments of the present application, referring to Figure 1 、 Figure 5As shown, the pressure building module further comprises a driving pump 22, the driving pump 22 is connected with the motor 21, and the driving pump 22 at least partially extends to the first liquid path block 11. The driving pump 22 is in communication with the flow path in the first liquid path block 11 for pressurizing the liquid in the first liquid path block 11. Specifically, the driving pump 22 is connected with the motor 21, and the motor 21 provides power for the driving pump 22, so that the driving pump 22 can quickly and continuously pressurize the liquid in the first liquid path block 11. Therefore, the brake assembly 10 can timely obtain sufficient and stable pressure under various working conditions, whether it is instantaneous high pressure demand in emergency braking or continuous pressure supply in regular braking, which can accurately meet the demand, thereby significantly improving the reliability and safety of the brake assembly 10.

[0068] In some embodiments of the present application, referring to Figures 4-5 As shown, the motor 21 has a driving shaft 211, the support 4 has a support through hole 42, and the driving shaft 211 is connected with the driving pump 22 and at least partially passes through the support through hole 42. In this way, the support 4 can provide support force for the driving shaft 211.

[0069] In some embodiments of the present application, referring to Figure 1 As shown, one end of the driving pump 22 extending to the first liquid path block 11 is supported on the first liquid path block 11. Specifically, the one end of the driving pump 22 extending to the first liquid path block 11 is supported on the first liquid path block 11, so that the driving pump 22 can obtain reliable support during work, and the displacement or deformation caused by the vibration and working pressure of the driving pump 22 itself is reduced. A stable connection structure is formed between the driving pump 22 and the first liquid path block 11, which can effectively resist various vibrations and impacts generated during the driving of the vehicle 100, thereby enhancing the structural stability of the entire brake assembly 10, reducing the risk of component damage, and prolonging the service life of the brake assembly 10.

[0070] In some embodiments of the present application, referring to Figure 1 As shown, the first liquid path block 11 has a first liquid path through hole 111, and the driving pump 22 comprises a pump body pipe 221 which is arranged in the first liquid path through hole 111. Specifically, the pump body pipe 221 is arranged in the first liquid path through hole 111, which provides an accurate positioning method for the driving pump 22 on the first liquid path block 11, so that the driving pump 22 can be quickly and accurately assembled in place during installation, reducing installation errors, and also ensuring the stability of the driving pump 22 during work. The pump body pipe 221 is tightly matched with the first liquid path through hole 111, which can effectively resist the radial displacement caused by external forces such as vibration and impact, ensure that the driving pump 22 always remains in the best working position, and enhance the structural stability of the entire brake assembly 10.

[0071] In some embodiments of the present application, referring to Figure 1As shown, the pump body pipe 221 is provided with a pump body inlet and a pump body outlet, and the hole wall of the first liquid path through hole 111 is provided with a liquid path block inlet and a liquid path block outlet. The pump body outlet is in communication with the liquid path block inlet, and the pump body inlet is in communication with the liquid path block outlet. Specifically, the pump body inlet is in communication with the liquid path block outlet, and the pump body outlet is in communication with the liquid path block inlet, thereby constructing a clear and efficient brake fluid circulation path between the pump body pipe 221 and the first liquid path block 11. When the driving pump 22 is working, it can ensure that the brake fluid continuously and stably circulates in the braking system, thereby providing sufficient pressure reserve for the braking system at any time, and meeting the demand for braking force in different braking scenarios.

[0072] In some embodiments of the present application, referring to Figure 1 As shown, the pump body pipe 221 is provided with a first sealing sleeve and a second sealing sleeve at the matching position of the pump body pipe 221 and the first liquid path through hole 111, and the pump body outlet, the liquid path block inlet, the pump body inlet and the liquid path block outlet are arranged between the first sealing sleeve and the second sealing sleeve. Specifically, the first sealing sleeve and the second sealing sleeve are arranged at the matching position of the pump body pipe 221 and the first liquid path through hole 111, thereby forming a double sealing protection mechanism, greatly enhancing the sealing performance between the pump body pipe 221 and the first liquid path block 11, and effectively preventing brake fluid from leaking from the gap between the pump body pipe 221 and the first liquid path block 11, thereby providing a solid guarantee for the safe and stable operation of the brake assembly 10.

[0073] In some embodiments of the present application, referring to Figure 1 , Figure 5 As shown, the pressure building module further comprises a driving pump 22, the driving pump 22 is connected with the motor 21, the driving pump 22 at least partially extends to the first liquid path block 11, and one end of the driving pump 22 close to the motor 21 is fixed to the support 4. Thus, the support 4 provides a reliable fixed support point for the driving pump 22, and especially after the one end of the driving pump 22 close to the motor 21 is fixed, the driving pump 22 can reduce its vibration and displacement when working. In a high-speed running and high-pressure working environment, stable support can prevent the internal parts of the driving pump 22 from being excessively worn or damaged due to shaking, thereby prolonging the service life of the driving pump 22 and improving the reliability of the driving pump 22.

[0074] Optionally, the connection relationship between the driving pump 22 and the support 4 can be adhesive connection, welding, bolt connection, etc.

[0075] In some embodiments of the present application, referring to Figure 1 , Figure 2 As shown, the first liquid path block 11 has a first mounting surface 112 (i.e. the left surface of the first liquid path block 11 in Figure 1 As shown, the second liquid path block 12 has a second mounting surface 122 (i.e. the left surface of the second liquid path block 12 in Figure 2The accommodation space 14 is formed within the range of the angle between the first mounting surface 112 and the second mounting surface 122. Specifically, the accommodation space 14 is formed within the range of the angle between the first mounting surface 112 and the second mounting surface 122, so as to make full use of the three-dimensional space between the first liquid path block 11 and the second liquid path block 12, realize the compact layout of the internal structure of the brake assembly 10, arrange more components (such as part of the components of the pressure building module) in the limited space of the brake assembly 10, improve the space utilization, and help to improve the compactness and rationality of the layout of the structure of the brake assembly 10.

[0076] In some embodiments of the present application, referring to Figure 2 As shown in the figure, the size of the first liquid path block 11 perpendicular to the first mounting surface 112 is A1, and the size of the second liquid path block 12 perpendicular to the second mounting surface 122 is A2; 20mm≤A1≤50mm, 20mm≤A2≤30mm, for example, A1 can be 20mm, 30mm, 40mm, 50mm, and A2 can be 20mm, 25mm, 30mm. The present application improves the space utilization by reasonably arranging the two hydraulic units 1.

[0077] In some embodiments of the present application, referring to Figure 1 , Figure 2 As shown in the figure, the range of the angle between the first mounting surface 112 and the second mounting surface 122 is 70°-110°, for example, the angle between the first mounting surface 112 and the second mounting surface 122 can be 70°, 80°, 90°, 100°, 110°.

[0078] In some embodiments of the present application, referring to Figure 1 , Figure 3 , Figure 7 , Figure 9 As shown in the figure, the projection of the motor 21 on the first plane parallel to the first mounting surface 112 at least partially overlaps the projection of the first liquid path block 11 on the first plane. Specifically, the projection of the motor 21 on the first plane parallel to the first mounting surface 112 at least partially overlaps the projection of the first liquid path block 11, which means that the motor 21 and the first liquid path block 11 can share part of the space in the same plane dimension. This greatly optimizes the layout of the brake assembly 10 in the plane direction, so that the overall structure is more compact. Especially in vehicles 100 and other devices that are extremely strict in space layout, valuable space resources can be effectively saved, providing more possibilities for the rational arrangement of other components, and improving the overall space utilization of the device.

[0079] In some embodiments of the present application, referring to Figure 1 , Figure 3 , Figure 7、 Figure 9 As shown in FIG. 10, the projection of the motor 21 on the first plane is located within the projection range of the first liquid passage block 11 on the first plane. Specifically, the projection of the motor 21 on the first plane is completely located within the projection range of the first liquid passage block 11, which makes the spatial layout of the brake assembly 10 in the first plane direction highly compact. In the limited installation space of the vehicle 100 or other equipment, such a layout can make full use of the space around the first liquid passage block 11, avoid the waste of space caused by the motor 21 occupying additional space alone, leave more room for the arrangement of other components, and help to optimize the overall layout of the brake assembly 10 and improve the space utilization.

Specifically, the projection of the motor 21 on the first plane is completely located within the projection range of the first liquid passage block 11, which makes the spatial layout of the brake assembly 10 in the first plane direction highly compact. In the limited installation space of the vehicle 100 or other equipment, such a layout can make full use of the space around the first liquid passage block 11, avoid the waste of space caused by the motor 21 occupying additional space alone, leave more room for the arrangement of other components, and help to optimize the overall layout of the brake assembly 10 and improve the space utilization.

[0083] Specifically, the signal processing unit 5 is placed in the receiving groove 41 of the support 4, which provides accurate positioning for the relative position of the rotating speed sensor sensing module 51 in the signal processing unit 5 and the motor 21, and is conducive to improving the stability of the rotating speed sensor sensing module 51. At the same time, the receiving groove 41 provides a relatively stable working environment for the signal processing unit 5, reduces the positional deviation caused by vibration, collision and other factors of the motor 21, so that the rotating speed sensor sensing module 51 can more accurately and stably detect the rotating speed signal of the motor 21, avoids signal fluctuation caused by shaking of the rotating speed sensor sensing module 51, and ensures that the control unit 3 obtains accurate rotating speed information of the motor 21.

[0084] In some embodiments of the present application, referring to Figure 1 , Figure 6 , Figure 7 As shown, the signal processing unit 5 further has a signal processing module 52, the signal processing module 52 is connected with the rotating speed sensor sensing module 51, and the signal processing module 52 is used to process the rotating speed signal detected by the rotating speed sensor sensing module 51 and transmit the processed rotating speed signal to the control unit 3.

[0085] In some embodiments of the present application, referring to Figure 1 , Figure 6 As shown, the brake assembly 10 further comprises a plug-in part 6, the plug-in part 6 is connected with the control unit 3 and the signal processing unit 5, and the rotating speed signal in the signal processing unit 5 is transmitted to the control unit 3 through the plug-in part 6. Specifically, the plug-in part 6 can provide a stable transmission channel for the rotating speed signal, ensure the tightness of the electrical connection between the control unit 3 and the signal processing unit 5, and effectively reduce the signal interruption or interference problem caused by poor contact. During the operation of the brake assembly 10, the vehicle 100 will experience various vibrations and bumps, and the plug-in part 6 can always keep reliable connection with the control unit 3 and the signal processing unit 5 by virtue of good mechanical stability, so as to ensure that the rotating speed signal is accurately transmitted from the signal processing unit 5 to the control unit 3, and lay a foundation for accurate control of the brake system.

[0086] In some embodiments of the present application, referring to Figure 1 , Figure 6 , the support 4 has a first plug hole, the first liquid path block 11 has a second plug hole, the plug 6 is connected with the signal processing unit 5 through the first plug hole, and the plug 6 passes through the second plug hole and is connected with the control unit 3. Specifically, the first plug hole of the support 4 and the second plug hole of the first liquid path block 11 provide accurate positioning for the plug 6, ensuring accurate connection position between the control unit 3 and the signal processing unit 5, avoiding poor contact or signal transmission problems caused by deviation of the plug position, and making the connection of the control unit 3 and the signal processing unit 5 more stable.

[0087] In some embodiments of the present application, referring to Figure 1 , Figure 6 , the driving pump 22 is provided with a third plug hole 222, and the plug 6 also passes through the third plug hole 222. Specifically, the plug 6 passes through the third plug hole 222 on the driving pump 22 to establish a stable connection between the signal processing unit 5 and the control unit 3, ensuring that the plug 6 can always maintain reliable connection by virtue of good mechanical stability even if it is affected by strong vibration, bumping and other external forces during operation of the brake system, ensuring that the rotation speed signal is accurately transmitted from the signal processing unit 5 to the control unit 3, laying a foundation for accurate control of the brake system.

[0088] In some embodiments of the present application, referring to Figure 1 , the brake assembly 10 includes a brake master cylinder and a push rod 131, the brake master cylinder is in communication with the flow path in the second liquid path block 12, and the end of the push rod 131 extending into the brake master cylinder is provided with a piston which is in sliding fit with the inner wall of the brake master cylinder. The push rod 131 is connected with the brake pedal. Specifically, the brake master cylinder and the push rod 131 constitute a master cylinder module 13, and the push rod 131 is directly connected with the brake pedal. When the brake pedal is stepped on, the push rod 131 can quickly transmit the force of the pedal to the piston in the brake master cylinder. Since the piston is in good sliding fit with the inner wall of the brake master cylinder, it can quickly respond to the pushing of the push rod 131, thereby immediately generating pressure on the brake fluid in the brake master cylinder, so that the components (such as the pedal simulator 7) of the brake assembly 10 can respond in a very short time, realizing sensitive brake response and providing a strong guarantee for the driving safety of the vehicle 100.

[0089] In some embodiments of the present application, the brake master cylinder is mounted on the second hydraulic block 12. Specifically, the second hydraulic block 12 has a master cylinder hole 121, and the brake master cylinder is mounted in the master cylinder hole 121 of the second hydraulic block 12. Specifically, the master cylinder hole 121 provides an accurate mounting position for the brake master cylinder, ensuring that the brake master cylinder can accurately cooperate with the second hydraulic block 12, helping to ensure the relative positional relationship between the components of the brake assembly 10, making the flow path and pressure transmission of the brake fluid more accurate and stable, thereby improving the overall performance and reliability of the brake assembly 10.

[0090] In related technologies, a single hydraulic block is often used to communicate the brake master cylinder and the wheel end, resulting in a complex design of the flow path in the hydraulic block, greatly increasing the processing difficulty and manufacturing cost of the hydraulic block. Moreover, due to the winding and interlaced flow path in the hydraulic block, the flow of the brake fluid is affected, and the overall performance of the brake system is reduced. In the present application, by designing the first hydraulic block 11 and the second hydraulic block 12 that are in communication with each other, the first hydraulic block 11 is connected to the wheel end, and the second hydraulic block 12 is connected to the brake master cylinder, which can effectively simplify the design of the flow path in the first hydraulic block 11 and the second hydraulic block 12, improve the processing precision and reduce the manufacturing cost. At the same time, the response speed and overall reliability of the brake system are significantly improved, providing stronger protection for the safe driving of the vehicle 100.

[0091] In some embodiments of the present application, the second hydraulic block 12 has a master cylinder hole 121, and a hydraulic chamber is formed in the master cylinder hole 121. The hydraulic chamber serves as a brake master cylinder and cooperates with the push rod 131 to generate pressure on the brake fluid in the second hydraulic block 12.

[0092] In some embodiments of the present application, the brake master cylinder is separated from the second hydraulic block 12, and the brake master cylinder is connected to the second hydraulic block 12 through a pipeline. The push rod 131 cooperates with the brake master cylinder to push the brake fluid through the pipeline to generate pressure on the second hydraulic block 12.

[0093] In some embodiments of the present application, referring to FIG. 1, Figure 1 As shown in FIG. 1, the brake assembly 10 further includes a mounting bracket 132 mounted on the second hydraulic block 12. The brake master cylinder is mounted on the second hydraulic block 12 through the mounting bracket 132. Specifically, the brake master cylinder is mounted on the second hydraulic block 12 through the mounting bracket 132, so that the brake master cylinder can always maintain a stable mounting state during the driving of the vehicle 100, even if subjected to various vibrations and impacts. This avoids affecting the braking performance due to displacement and enhances the structural stability of the entire brake assembly 10.

[0094] Optionally, the connection relationship between the mounting bracket 132 and the second hydraulic block 12 can be a threaded fastener connection, a rivet connection, a buckle connection, etc. For example, Figure 1As shown, the mounting bracket 132 is connected to the second liquid path block 12 by threaded fasteners.

[0095] In some embodiments of the present application, referring to Figure 1 , Figure 2 As shown, the support 4 is adjustably mounted on the second mounting surface 122 of the second liquid path block 12, and the mounting bracket 132 is a rotary body. By changing the position of the support 4 on the second liquid path block 12, the center of gravity of the brake assembly 10 can be arranged below or on the axis of the mounting bracket 132. Thus, during driving of the vehicle 100, it is beneficial to reduce the vibration caused by the braking process of the brake assembly 10.

[0096] In some embodiments of the present application, referring to Figure 1 As shown, the brake assembly 10 further comprises a pedal simulator 7, which is in communication with the flow path in the second liquid path block 12. The pedal simulator 7 receives the total amount of liquid in the second liquid path block 12 and simulates the size of the pedal resistance according to the total amount of liquid. Specifically, when the brake pedal is depressed, the push rod 131 can quickly transmit the force of the pedal to the piston in the brake master cylinder, and the piston in the brake master cylinder moves under force and pressurizes the brake fluid in the second liquid path block 12. Since the second liquid path block 12 is in communication with the pedal simulator 7, the brake fluid is transferred from the second liquid path block 12 to the pedal simulator 7, and the pedal simulator 7 simulates the resistance of the brake pedal according to the change in the total amount of liquid. Thus, the pedal simulator 7 can simulate the size of the pedal resistance according to the total amount of liquid in the second liquid path block 12, so that the driver can feel similar pedal feedback when braking as in a traditional hydraulic brake system, restoring the feel of the real brake pedal and allowing the driver to adapt without needing to re-adapt, thereby enhancing driving comfort and confidence.

[0097] In some embodiments of the present application, referring to Figure 1 As shown, the brake assembly 10 further comprises a liquid storage pot 8, which is in communication with the flow path in the second liquid path block 12 and is used to supply liquid to the second liquid path block 12. Specifically, the liquid storage pot 8 is in communication with the flow path in the second liquid path block 12 and can continuously provide brake fluid for the brake system. In the process of frequent braking, brake fluid may

In this way, compact installation of the brake assembly 10 as a whole can be achieved. The projection of the reservoir 8 and the pressure building device on the second mounting surface 122 at least partially overlapping means that the reservoir 8 and the pressure building device can be arranged at different heights or angles on the same plane, effectively reducing the space occupied by the brake assembly 10 inside the vehicle 100, providing more possibilities for the installation of other components and the overall layout of the vehicle 100, and helping to improve the utilization of the interior space of the vehicle 100.

[0099] In some embodiments of the present application, referring to Figure 1 As shown, the brake assembly 10 further comprises a control unit rear cover 9, which is installed on the control unit 3 and at least partially covers the outer surface of the control unit 3. Specifically, the control unit rear cover 9 can effectively block dust, mud, oil stains and other external pollutants from entering the interior of the control unit 3. During the driving of the vehicle 100, dust and mud raised by the road may damage the control unit 3. The protection of the control unit rear cover 9 can prevent these pollutants from adhering to the electronic components of the control unit 3, avoiding problems such as short circuit, poor contact, etc. affecting the performance of the control unit 3, and is conducive to prolonging the service life of the control unit 3.
