DETAILED DESCRIPTION

[0049] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0050] In the description of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0051] Combine the following Figure 1-Figure 10 A brake assembly 10 and a vehicle 100 having the brake assembly 10 according to an embodiment of the present application are described in detail.

[0052] See also Figure 1-Figure 3 , Figure 7-Figure 9 As shown, the brake assembly 10 according to the embodiment of the present application includes a hydraulic unit 1, a pressure building module and a control unit 3. The hydraulic unit 1 forms a accommodating space 14. The pressure building module includes a motor 21. The motor 21 is at least partially arranged in the accommodating space 14. The pressure building module is used to pressurize the liquid in the hydraulic unit 1. The control unit 3 is arranged on the outside of the accommodating space 14, and the pressure building module is connected to the control unit 3.

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

[0054] The accommodation space 14 may be formed by a depression of the hydraulic unit 1, for example Figure 1 In the example, the hydraulic unit 1 is constructed in an L shape, and the space enclosed by the L-shaped hydraulic unit 1 forms the accommodating space 14.

[0055] In the related art, the pressure building module and the control unit are both arranged on the side of the hydraulic unit, but the pressure building module is large in size. Placing the pressure building module on one side of the hydraulic unit or setting a recess (3 to 5 mm deep) for installing the pressure building module still cannot effectively reduce the impact of the volume of the pressure building module.

[0056] According to the brake assembly 10 of the embodiment of the present application, the motor 21 is at least partially disposed in the accommodating space 14 of the hydraulic unit 1, so that the hydraulic unit 1 and the pressure building module are highly integrated, thereby reducing the space occupied by the brake assembly 10 and making the brake assembly 10 compact.

[0057] The following description takes the brake assembly 10 as an example of being applicable to the brake system of the vehicle 100 . It should be noted that the brake assembly can also be applied to the brake systems of other devices, which will not be described in detail here.

[0058] In some embodiments of the present application, see Figure 1-Figure 3 As shown, the hydraulic unit 1 includes a first liquid circuit block 11 and a second liquid circuit block 12, the pressure building module is at least used to pressurize the liquid in the first liquid circuit block 11, the second liquid circuit block 12 is installed in the first liquid circuit block 11, the flow path in the first liquid circuit block 11 is connected to the flow path in the second liquid circuit block 12, and the first liquid circuit block 11 is connected to the second liquid circuit block 12 to form a accommodating space 14.

[0059] Specifically, the first fluid circuit block 11 can be connected to the wheel end, and the pressure building module pressurizes the first fluid circuit block 11, ensuring that the hydraulic pressure flowing to the wheel end has sufficient pressure and stability, so that the wheel end responds quickly during braking, generates a strong and stable braking force, effectively shortens the braking distance, and improves braking safety. The second fluid circuit block 12 is installed on the first fluid circuit block 11, and the two are closely combined, which enhances 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, see Figure 1-Figure 4 , Figure 7-Figure 9 As shown, the control unit 3 is installed on one side of the first fluid circuit block 11, and the motor 21 is located on the other side of the first fluid circuit block 11, and 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 fluid circuit block 11, and the motor 21 is placed in the accommodation space 14, which makes full use of the limited space, makes the brake assembly 10 compact, avoids mutual interference between components, and is conducive to integration in the limited space of the vehicle 100. At the same time, the control unit 3 and the motor 21 are separately placed on both sides of the first fluid circuit 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, see Figure 1-Figure 4 , Figure 7-Figure 9 As shown, the second fluid circuit block 12 and the motor 21 are located on the same side of the first fluid circuit block 11. Therefore, the second fluid circuit block 12 and the motor 21 are arranged on the same side of the first fluid circuit block 11, and the motor 21 is arranged in the space formed by the lower side of the second fluid circuit block 12 and the left side of the first fluid circuit block 11, which can greatly optimize the spatial 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 entire brake assembly 10 more integrated, free up more space for the arrangement of other equipment or components, and help improve the rationality and compactness of the overall layout of the brake assembly 10.

[0062] In some embodiments of the present application, see Figure 1-Figure 4 , Figure 7-Figure 9As shown, the motor 21 is installed on the second fluid circuit block 12. Therefore, this installation method further optimizes the spatial layout of the brake assembly 10. The motor 21 is installed on the second fluid circuit block 12, which reduces the independent installation space requirements and makes the entire brake assembly 10 more compact. In the vehicle 100 or other equipment with limited space and strict layout requirements, this compact design can better utilize the limited space, provide more possibilities for the arrangement of other components, and help improve the rationality and compactness of the overall structure of the vehicle 100.

[0063] In some embodiments of the present application, see Figure 1-Figure 3 , Figure 5 , Figure 7-Figure 9 As shown, the brake assembly 10 also includes a support member 4, which is mounted on the second fluid circuit block 12, and the motor 21 is mounted on the support member 4, that is, the motor 21 is mounted on the second fluid circuit block 12 through the support member 4. Specifically, the support member 4 is mounted on the second fluid circuit block 12, and the motor 21 is mounted on the support member 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 fluid circuit block 12 through the support member 4, reducing the impact 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 member 4, the arrangement position of the motor 21 relative to the second fluid circuit block 12 can be more flexible.

[0064] The motor 21 and the support member 4 can both be disposed in the accommodating space 14 , thereby fully utilizing the accommodating space 14 without occupying additional external space.

[0065] Optionally, the support member 4 and the second fluid circuit block 12 may be connected by threaded fasteners, rivets, snap-fit ​​connections, etc. Figure 1 As shown, the support member 4 is connected to the second fluid circuit block 12 by threaded fasteners.

[0066] Optionally, the motor 21 and the support member 4 may be connected by threaded fasteners, rivets, snap-fit ​​connections, etc. Figure 1 As shown, the motor 21 is connected to the support member 4 by threaded fasteners.

[0067] In some embodiments of the present application, see Figure 1 , Figure 5As shown, the pressure building module also includes a driving pump 22, which is connected to the motor 21. The driving pump 22 at least partially extends to the first fluid circuit block 11, and the driving pump 22 is connected to the flow path in the first fluid circuit block 11 to increase the pressure of the liquid in the first fluid circuit block 11. Specifically, the driving pump 22 is connected to the motor 21, and the motor 21 provides power for the driving pump 22, so that the driving pump 22 can quickly and continuously increase the pressure of the liquid in the first fluid circuit block 11, so that the brake assembly 10 can obtain sufficient and stable pressure in a timely manner under various working conditions, whether it is the instantaneous high pressure demand during emergency braking or the continuous pressure supply during conventional braking, which can be accurately met, thereby significantly improving the reliability and safety of the brake assembly 10.

[0068] In some embodiments of the present application, see Figure 4-Figure 5 As shown, the motor 21 has a drive shaft 211, the support member 4 has a support through hole 42, the drive shaft 211 is connected to the drive pump 22, and the drive shaft 211 at least partially passes through the support through hole 42. Therefore, the support member 4 can provide support force for the drive shaft 211.

[0069] In some embodiments of the present application, see Figure 1 As shown, one end of the driving pump 22 extending toward the first fluid circuit block 11 is supported by the first fluid circuit block 11. Specifically, one end of the driving pump 22 extending toward the first fluid circuit block 11 is supported by the first fluid circuit block 11, so that the driving pump 22 can obtain reliable support during operation, reducing the displacement or deformation caused by the vibration of the driving pump 22 itself and the working pressure, and forming a stable connection structure between the driving pump 22 and the first fluid circuit 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 extending the service life of the brake assembly 10.

[0070] In some embodiments of the present application, see Figure 1 As shown, the first fluid circuit block 11 has a first fluid circuit through hole 111, and the driving pump 22 includes a pump body tube 221, and the pump body tube 221 is inserted into the first fluid circuit through hole 111. Specifically, the pump body tube 221 is inserted into the first fluid circuit through hole 111, providing a precise positioning method for the driving pump 22 on the first fluid circuit 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 operation. The pump body tube 221 is tightly matched with the first fluid circuit through hole 111, which can effectively resist radial displacement caused by external forces such as vibration and impact, ensuring that the driving pump 22 always remains in the best working position, and enhancing the structural stability of the entire brake assembly 10.

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

[0072] In some embodiments of the present application, see Figure 1 As shown, the first sealing sleeve and the second sealing sleeve are provided at the matching position of the pump body tube 221 and the first liquid circuit through hole 111, and the pump body outlet, the liquid circuit block inlet, the pump body inlet and the liquid circuit 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 provided at the matching position of the pump body tube 221 and the first liquid circuit through hole 111, forming a double sealing protection mechanism, greatly enhancing the sealing between the pump body tube 221 and the first liquid circuit block 11, and being able to effectively prevent the brake fluid from leaking from the matching gap between the pump body tube 221 and the first liquid circuit block 11, providing a solid guarantee for the safe and stable operation of the brake assembly 10.

[0073] In some embodiments of the present application, see Figure 1 , Figure 5 As shown, the pressure building module also includes a driving pump 22, which is connected to the motor 21, and the driving pump 22 at least partially extends toward the first fluid circuit block 11, and one end of the driving pump 22 close to the motor 21 is fixed to the support member 4. Thus, the support member 4 provides a reliable fixed support point for the driving pump 22, especially after the end of the driving pump 22 close to the motor 21 is fixed, the driving pump 22 can reduce its own vibration and displacement when working. Under high-speed operation and high-pressure working environment, the stable support can prevent the internal parts of the driving pump 22 from excessive wear or damage due to shaking, thereby extending 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 member 4 can be an adhesive connection, welding, bolt connection, etc.

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

[0076] In some embodiments of the present application, see Figure 2 As shown, the dimension of the first fluid circuit block 11 perpendicular to the first mounting surface 112 is A1, and the dimension of the second fluid circuit 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 space utilization by dividing the hydraulic unit 1 into two and by reasonable layout.

[0077] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the angle between the first mounting surface 112 and the second mounting surface 122 ranges from 70° to 110°. For example, the angle between the first mounting surface 112 and the second mounting surface 122 may be 70°, 80°, 90°, 100°, or 110°.

[0078] In some embodiments of the present application, see Figure 1 , Figure 3 , Figure 7 , Fig. 9 As shown, the projection of the motor 21 on the first plane parallel to the first mounting surface 112 at least partially overlaps with the projection of the first fluid circuit 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 with the projection of the first fluid circuit block 11, which means that in the same plane dimension, the motor 21 and the first fluid circuit block 11 can share part of the space. This greatly optimizes the layout of the brake assembly 10 in the plane direction, making the overall structure more compact. Especially in equipment such as the vehicle 100 that has extremely strict requirements on space layout, it can effectively save precious space resources, provide more possibilities for the reasonable arrangement of other components, and improve the overall space utilization of the equipment.

[0079] In some embodiments of the present application, see Figure 1 , Figure 3 , Figure 7, Fig. 9 As shown, the projection of the motor 21 on the first plane is within the projection range of the first fluid circuit block 11 on the first plane. Specifically, the projection of the motor 21 on the first plane is completely within the projection range of the first fluid circuit 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, this layout can make full use of the space around the first fluid circuit 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, help to optimize the overall layout of the brake assembly 10, and improve space utilization.

[0080] In some embodiments of the present application, see Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the projection of the motor 21 on the second plane parallel to the second mounting surface 122 at least partially overlaps with the projection of the second fluid circuit block 12 on the second plane. Specifically, the projection of the motor 21 on the second plane at least partially overlaps with the projection of the second fluid circuit block 12, which means that in the same plane dimension, the motor 21 and the second fluid circuit block 12 can share part of the space, optimizing the layout of the brake assembly 10 in the second plane direction, making the overall structure more compact. Especially in vehicles 100 or other equipment with extremely strict requirements on space layout, it can effectively save precious space resources, provide more possibilities for the reasonable arrangement of other components, and improve the overall space utilization of the equipment.

[0081] In some embodiments of the present application, see Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the projection of the motor 21 on the second plane is within the projection range of the second fluid circuit block 12 on the second plane. Specifically, the projection of the motor 21 on the second plane is completely within the projection range of the second fluid circuit block 12, which makes the spatial layout of the brake assembly 10 in the second plane direction highly compact. In the limited installation space of the vehicle 100 or other equipment, this layout can make full use of the space around the second fluid circuit block 12, avoid the waste of space caused by the motor 21 occupying additional space alone, leave more room for the arrangement of other components, help to optimize the overall layout of the brake assembly 10, and improve space utilization.

[0082] In some embodiments of the present application, see Figure 1 , Figure 4 , Figure 6 , Figure 7As shown, the brake assembly 10 also includes a signal processing unit 5 and a support member 4, the support member 4 is installed on the second fluid circuit block 12, the motor 21 is installed on the support member 4, the signal processing unit 5 is electrically connected to the control unit 3, the support member 4 has a receiving groove 41, the signal processing unit 5 is located in the receiving groove 41, the signal processing unit 5 has a speed sensor sensing module 51, and the speed sensor sensing module 51 is used to detect the speed signal of the motor 21.

[0083] Specifically, placing the signal processing unit 5 in the receiving groove 41 of the support member 4 provides accurate positioning for the relative position of the speed sensor sensing module 51 and the motor 21 in the signal processing unit 5, which is conducive to improving the stability of the 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 position deviation caused by factors such as vibration and collision of the motor 21, and enables the speed sensor sensing module 51 to detect the speed signal of the motor 21 more accurately and stably, avoiding signal fluctuations caused by shaking of the speed sensor sensing module 51, and ensuring that the control unit 3 obtains accurate speed information of the motor 21.

[0084] In some embodiments of the present application, see Figure 1 , Figure 6 , Figure 7 As shown, the signal processing unit 5 also has a signal processing module 52, which is connected to the speed sensor sensing module 51. The signal processing module 52 is used to process the speed signal detected by the speed sensor sensing module 51 and transmit the processed speed signal to the control unit 3. Specifically, the signal processing module 52 is connected to the speed sensor sensing module 51, and can perform special processing on the detected speed signal to make the speed signal purer and more accurate, so that the control unit 3 receives an accurate and stable speed signal, thereby realizing precise control of the speed of the motor 21 according to the speed signal.

[0085] In some embodiments of the present application, see Figure 1 , Figure 6 As shown, the brake assembly 10 also includes a connector 6, which connects the control unit 3 and the signal processing unit 5, and the speed signal in the signal processing unit 5 is transmitted to the control unit 3 through the connector 6. Specifically, the connector 6 can provide a stable transmission channel for the 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 caused by poor contact. During the operation of the brake assembly 10, the vehicle 100 will experience various vibrations and bumps. The connector 6, with its good mechanical stability, always maintains a reliable connection with the control unit 3 and the signal processing unit 5, ensuring that the speed signal is accurately transmitted from the signal processing unit 5 to the control unit 3, laying the foundation for the precise control of the brake system.

[0086] In some embodiments of the present application, see Figure 1 , Figure 6 As shown, the support member 4 has a first plug hole, the first fluid circuit block 11 has a second plug hole, the plug connector 6 is connected to the signal processing unit 5 through the first plug hole, and the plug connector 6 passes through the second plug hole and is connected to the control unit 3. Specifically, the first plug hole of the support member 4 and the second plug hole of the first fluid circuit block 11 provide accurate positioning for the plug connector 6, ensuring that the connection position between the control unit 3 and the signal processing unit 5 is accurate, avoiding poor contact or signal transmission problems caused by plug position deviation, making the connection between the control unit 3 and the signal processing unit 5 more stable, and during the operation of the brake assembly 10, even if it is subjected to external forces such as vibration and bumps of the vehicle 100, the plug connector 6 can maintain a good connection state to ensure stable transmission of the speed signal.

[0087] In some embodiments of the present application, see Figure 1 , Figure 6 As shown, the driving pump 22 is provided with a third plug hole 222, and the plug connector 6 also passes through the third plug hole 222. Specifically, the plug connector 6 passes through the third plug hole 222 on the driving pump 22, and establishes a stable connection between the signal processing unit 5 and the control unit 3, ensuring that when the braking system is running, even if it is affected by strong vibration, bumps and other external forces, the plug connector 6 always maintains a reliable connection with good mechanical stability, ensuring that the speed signal is accurately transmitted from the signal processing unit 5 to the control unit 3, laying a foundation for the precise control of the braking system.

[0088] In some embodiments of the present application, see Figure 1 As shown, the brake assembly 10 includes a brake master cylinder and a push rod 131, the brake master cylinder is connected to the flow path in the second fluid circuit block 12, and one end of the push rod 131 extending into the brake master cylinder is provided with a piston, the piston is slidably matched with the inner wall of the brake master cylinder, and the push rod 131 is connected to the brake pedal. Specifically, the brake master cylinder and the push rod 131 constitute the master cylinder module 13, the push rod 131 is directly connected to the brake pedal, and 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 and the inner wall of the brake master cylinder slide well, it can quickly respond to the push of the push rod 131, and then immediately generate pressure on the brake fluid in the brake master cylinder, so that the components of the brake assembly 10 (such as the pedal simulator 7) can react in a very short time, achieve sensitive braking response, and provide a strong guarantee for the driving safety of the vehicle 100.

[0089] In some embodiments of the present application, the brake master cylinder is installed in the second fluid circuit block 12. Specifically, the second fluid circuit block 12 has a master cylinder hole 121, and the brake master cylinder is installed in the master cylinder hole 121 of the second fluid circuit block 12. Specifically, the master cylinder hole 121 provides a precise installation position for the brake master cylinder, ensuring that the brake master cylinder can accurately cooperate with the second fluid circuit block 12, which helps to ensure the relative position relationship between the various 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 the related art, a single fluid circuit block is often used to connect the brake master cylinder and the wheel end respectively, which makes the design of the flow path in the fluid circuit block too complicated, greatly increases the processing difficulty and manufacturing cost of the fluid circuit block, and because the flow path in the fluid circuit block is winding and staggered, it affects the circulation effect of the brake fluid and reduces the overall performance of the brake system. In the present application, by designing a first fluid circuit block 11 and a second fluid circuit block 12 that are interconnected, the first fluid circuit block 11 is connected to the wheel end, and the second fluid circuit block 12 is connected to the brake master cylinder, the flow path design in the first fluid circuit block 11 and the second fluid circuit block 12 can be effectively simplified, the processing accuracy is improved, and the manufacturing cost is reduced. At the same time, the response speed and overall reliability of the brake system are significantly improved, providing a stronger guarantee for the safe driving of the vehicle 100.

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

[0092] In some embodiments of the present application, the brake master cylinder is separated from the second fluid circuit block 12 and is connected to the second fluid circuit 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 fluid circuit block 12.

[0093] In some embodiments of the present application, see Figure 1 As shown, the brake assembly 10 further includes a mounting bracket 132, the mounting bracket 132 is mounted on the second fluid circuit block 12, and the brake master cylinder is mounted on the second fluid circuit block 12 through the mounting bracket 132. Specifically, the brake master cylinder is mounted on the second fluid circuit block 12 through the mounting bracket 132, so that the brake master cylinder can always maintain a stable installation state during the driving process of the vehicle 100 even if it is subjected to various vibrations and impacts, thereby avoiding the influence of the braking performance due to displacement, and enhancing the structural stability of the entire brake assembly 10.

[0094] Optionally, the connection relationship between the mounting bracket 132 and the second fluid circuit block 12 can be a threaded fastener connection, a rivet connection, a snap connection, etc. Figure 1As shown, the mounting bracket 132 is connected to the second fluid circuit block 12 via threaded fasteners.

[0095] In some embodiments of the present application, see Figure 1 , Figure 2 As shown, the support member 4 is adjustably mounted on the second mounting surface 122 of the second fluid circuit block 12, and the mounting bracket 132 is a rotating body. By changing the position of the support member 4 on the second fluid circuit block 12, the center of gravity of the brake assembly 10 can be arranged below or on the axis of the mounting bracket 132. Therefore, during the driving process of the vehicle 100, the vibration caused by the braking process of the brake assembly 10 is reduced.

[0096] In some embodiments of the present application, see Figure 1 As shown, the brake assembly 10 also includes a pedal simulator 7, which is connected to the flow path in the second fluid circuit block 12. The pedal simulator 7 receives the liquid in the second fluid circuit block 12 and simulates the size of the pedal resistance according to the total amount of liquid. Specifically, 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. The piston in the brake master cylinder moves under the force and pressurizes the brake fluid in the second fluid circuit block 12. Since the second fluid circuit block 12 is connected to the pedal simulator 7, the brake fluid is transmitted from the second fluid circuit block 12 to the pedal simulator 7. According to the change of the total amount of liquid, the pedal simulator 7 simulates the resistance of the brake pedal. Therefore, the pedal simulator 7 can simulate the size of the pedal resistance according to the total amount of liquid in the second fluid circuit block 12, so that the driver can feel the pedal feedback similar to the traditional hydraulic brake system when braking, restore the foot feel of the real brake pedal, and the driver does not need to re-adapt, which enhances the driving comfort and confidence.

[0097] In some embodiments of the present application, see Figure 1 As shown, the brake assembly 10 also includes a fluid reservoir 8, which is connected to the flow path in the second fluid circuit block 12, and the fluid reservoir 8 is used to supply fluid to the second fluid circuit block 12. Specifically, the fluid reservoir 8 is connected to the flow path in the second fluid circuit block 12, and can continuously provide brake fluid to the brake system. During frequent braking, the brake fluid will be lost. The presence of the fluid reservoir 8 can replenish the brake fluid in time to ensure that there is always sufficient brake fluid in the brake system, thereby maintaining a stable pressure in the brake system. Stable pressure ensures that the braking force is uniform and reliable each time braking, allowing the vehicle 100 to slow down or stop safely and smoothly.

[0098] In some embodiments of the present application, see Figure 1 , Figure 2 , Figure 7 , Figure 8As shown, the projections of the fluid reservoir 8 and the pressure-building device on the second mounting surface 122 of the second hydraulic block 12 at least partially overlap. As a result, the overall compact installation of the brake assembly 10 can be achieved. The partial overlap of the projections of the fluid reservoir 8 and the pressure-building device on the second mounting surface 122 means that the fluid 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 rate of the internal space of the vehicle 100.

[0099] In some embodiments of the present application, see Figure 1 As shown, the brake assembly 10 further includes a control unit rear cover 9, which is mounted 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 prevent external pollutants such as dust, dirt, and oil from entering the control unit 3. During the driving of the vehicle 100, dust and dirt raised by the road surface may cause damage to 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, avoid affecting the performance of the control unit 3 due to problems such as short circuits and poor contact, and help to extend the service life of the control unit 3.

[0101] According to the vehicle 100 of another embodiment of the present application, the brake assembly 10 thereof is configured such that the hydraulic unit 1 is highly integrated with the pressure building module by at least partially disposing the motor 21 in the accommodating space 14 of the hydraulic unit 1, thereby reducing the space occupied by the brake assembly 10, making the brake assembly 10 compact, and improving the structural stability of the brake assembly 10.
