[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0043] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a class, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0044] It should be understood that "some embodiments" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, "in some embodiments" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0045] A liquid storage pot, brake assembly and vehicle provided by the present application will be described in detail below by listing specific embodiments.

[0046] This application provides a liquid storage container. Figure 1 This is a front and side view of a liquid storage container according to an embodiment of this application. Figure 2 This is a schematic diagram of the back side of a liquid storage container in an embodiment of this application, with reference to... Figure 1 and Figure 2 The liquid storage tank has a side wall 1, and the side wall 1 is provided with at least one liquid outlet, which is adapted to be connected to the liquid inlet pipe of the hydraulic device.

[0047] Specifically, refer to Figure 1 As shown, the liquid reservoir has a first direction X, a second direction Z, and a third direction Y. The first direction X, the second direction Z, and the third direction Y intersect each other. In some embodiments, the first direction X, the second direction Z, and the third direction Y can be set to be mutually perpendicular. "Perpendicular" includes not only absolute perpendicularity but also generally understood approximately perpendicularity, such as when the angle between each pair of the first direction X, the second direction Z, and the third direction Y is 89° to 91°. In this embodiment, the first direction X can be considered the width direction of the liquid reservoir, the second direction Z can be considered the height direction of the liquid reservoir, and the third direction Y can be considered the length direction of the liquid reservoir.

[0048] The reservoir has a sidewall 1 located in the plane containing the second direction Z and the third direction Y. Two surfaces of the reservoir opposite each other along the first direction X are considered as the sidewall 1. The sidewall 1 has at least one outlet, suitable for allowing the brake fluid stored in the reservoir to flow out. The brake fluid plays a role in the braking system, including energy transfer, heat dissipation, lubrication, and corrosion and rust prevention. The outlet on the reservoir is suitable for connecting to the inlet pipe of the hydraulic device. When the driver depresses the brake pedal, the hydraulic device draws brake fluid from the reservoir. The brake fluid reaches the hydraulic device through the outlet and is then transmitted to the brake components (such as brake calipers), thereby generating braking force and braking the wheels. During braking, the brake fluid continuously circulates within the braking system.

[0049] In addition, the liquid outlet is arranged on the side wall 1, and the liquid outlet direction of the liquid outlet intersects the side wall 1, wherein the liquid outlet direction of the liquid outlet is in the same direction as the extension direction of the liquid outlet, that is, the extension direction of the liquid outlet intersects the side wall 1. For example, the included angle between the extension direction of the liquid outlet and the side wall 1 can be 60°-120°, and in this range, the lateral liquid outlet of the liquid storage pot can be realized, and the situation that the oil liquid blocks the liquid outlet can be reduced. Of course, in actual application, the included angle between the extension direction of the liquid outlet and the side wall 1 needs to be set according to the position and angle of the liquid inlet pipeline on the hydraulic device, so as to ensure that the liquid outlet can be reliably connected with the liquid inlet pipeline. In some embodiments, the included angle between the extension direction of the liquid outlet and the side wall 1 is 90°, which is more convenient for processing the liquid outlet and assembling and connecting the liquid outlet with the liquid inlet pipeline.

[0050] In the embodiments of the present application, the liquid outlet is arranged on the side wall 1 of the liquid storage pot, so that the liquid outlet mode of the liquid storage pot is lateral liquid outlet, that is, the liquid outlet on the liquid storage pot can be connected with the liquid inlet pipeline on the hydraulic device laterally, so that the liquid storage pot can be installed on the side of the hydraulic device, thereby facilitating the reduction of the space occupied by the liquid storage pot in the front cabin height direction and the installation and layout of other components in the front cabin.

[0051] Optionally, in some embodiments of the present application, at least one connecting piece is further arranged on the side wall 1, and the connecting piece is suitable for fixedly connecting the liquid storage pot with the hydraulic device. The connecting piece can be a connecting hole for a fastener such as a bolt, a screw or a rivet to pass through, so as to assemble and connect the liquid storage pot and the hydraulic device together through the connecting piece. The connecting piece can also be a protrusion, a groove or a hook, so as to clamp the liquid storage pot and the hydraulic device together through the connecting piece. The specific type of the connecting piece is not limited in the embodiments. Therefore, in the embodiments, the liquid storage pot is installed on the side of the hydraulic device through the connecting piece on the side wall 1, which facilitates the reduction of the space occupied by the liquid storage pot in the front cabin height direction and the installation and layout of other components in the front cabin.

[0052] Optionally, in some embodiments of the present application, the at least one connecting piece includes a first connecting piece 11, the first connecting piece 11 is arranged to extend along a first direction X, and the first connecting piece 11 is suitable for realizing the fixed connection of the liquid storage pot and the hydraulic device in the first direction X. The first direction X intersects the side wall 1. Specifically, as shown in FIG. 1, the first connecting piece 11 is a connecting hole, and the first connecting piece 11 is arranged to extend along the first direction X, that is, the axis of the connecting hole extends along the first direction X, so that the fastener needs to pass through the connecting hole along the first direction X, so that the first connecting piece 11 can realize the fixed connection of the liquid storage pot and the hydraulic device in the first direction X. Of course, the first connecting piece 11 can also be a connecting shaft or a limiting piece, which can also be arranged to extend along the first direction X. Figure 1

Specifically, referring to Figure 1 It is shown that the second connecting member 12 protrudes from the surface of the side wall 1, and a connecting hole is formed on the second connecting member 12, the axis of the connecting hole extends along the second direction Z, so that the fastener needs to be threaded into the connecting hole along the second direction Z, so that the second connecting member 12 can realize the fixed connection of the liquid storage pot and the hydraulic device in the second direction Z. Of course, the second connecting member 12 can also be a connecting shaft, a limiting member, etc., which all extend along the second direction Z.

[0054] In combination with the foregoing embodiments, the connecting member on the side wall 1 comprises the first connecting member 11 and the second connecting member 12, the first connecting member 11 can realize the fixed connection of the liquid storage pot and the hydraulic device in the first direction X, and the second connecting member 12 can realize the fixed connection of the liquid storage pot and the hydraulic device in the second direction Z, so that through the first connecting member 11 and the second connecting member 12, the fixed connection of the liquid storage pot and the hydraulic device in two directions can be realized, which is more helpful to improve the connection reliability and stability of the liquid storage pot and the hydraulic device, and provides protection for the communication and sealing of the liquid outlet on the liquid storage pot and the liquid inlet pipeline on the hydraulic device, and reduces the probability of oil leakage between the liquid storage pot and the hydraulic device.

[0055] Optionally, in some embodiments of the present application, the first connecting member 11 and the second connecting member 12 are arranged on different sides of the side wall 1 along the second direction Z; and / or, the first connecting member 11 and the second connecting member 12 are arranged on different sides of the side wall 1 along a third direction Y, wherein the third direction Y intersects the first direction X and the second direction Z, respectively.

[0056] Specifically, the liquid storage pot also has a bottom wall 2 and a top wall, the bottom wall 2 and the top wall are oppositely arranged along the second direction Z, and the bottom wall 2 and the top wall are adjacent to the side wall 1, in some embodiments, the first connecting member 11 and the second connecting member 12 are arranged on different sides of the side wall 1 along the second direction Z, for example, referring to Figure 1 It is shown that the first connecting member 11 is arranged on one side close to the bottom wall 2, and the second connecting member 12 is arranged on one side close to the top wall, so that the first connecting member 11 and the second connecting member 12 are distributed more dispersedly on the side wall 1, which is helpful to improve the phenomenon of stress concentration at the connecting part, and further improve the connection reliability and stability of the liquid storage pot and the hydraulic device. Of course, the first connecting member 11 can also be arranged on one side close to the top wall, and the second connecting member 12 is correspondingly arranged on one side close to the bottom wall 2, which can be arranged according to actual needs, and this embodiment is not limited.

[0057] Alternatively, in some embodiments, the first connecting member 11 and the second connecting member 12 are arranged at different sides of the side wall 1 along the third direction Y, for example, referring to Figure 1 As shown, the first connecting member 11 is arranged at the left side of the side wall 1, and the second connecting member 12 is arranged at the right side of the side wall 1, so that the first connecting member 11 and the second connecting member 12 are more dispersed on the side wall 1, thereby improving the connection reliability and stability of the liquid storage pot and the hydraulic device. Of course, the first connecting member 11 can also be arranged at the right side of the side wall 1, and the second connecting member 12 is correspondingly arranged at the left side of the side wall 1, which can be set according to actual needs, and this embodiment is not limited.

[0058] Alternatively, in some embodiments, the first connecting member 11 and the second connecting member 12 are arranged at different sides of the side wall 1 along the second direction Z and the third direction Y, respectively, that is, the first connecting member 11 and the second connecting member 12 are distributed at the opposite corners of the side wall 1 to achieve a better effect and effectively improve the connection reliability and stability of the liquid storage pot and the hydraulic device.

[0059] Alternatively, in some embodiments of the present application, the first connecting member 11 and the second connecting member 12 are adapted to be connected to two adjacent surfaces of the hydraulic device, respectively. Specifically, since the first connecting member 11 can achieve the fixed connection of the liquid storage pot and the hydraulic device in the first direction X, and the second connecting member 12 can achieve the fixed connection of the liquid storage pot and the hydraulic device in the second direction Z, the first connecting member 11 and the second connecting member 12 can be connected to two adjacent surfaces of the hydraulic device, respectively, for example, the first connecting member 11 can be connected to the side surface of the hydraulic device, and the second connecting member 12 can be connected to the top surface of the hydraulic device. In this way, the liquid storage pot is arranged on the side of the hydraulic device, and the multi-surface connection of the liquid storage pot and the hydraulic device is achieved, which helps to improve the connection reliability and stability of the liquid storage pot and the hydraulic device.

[0060] Alternatively, in some embodiments of the present application, the bottom wall 2 is provided with a third connecting member 20, and the third connecting member 20 is adapted to fixedly connect the liquid storage pot and the hydraulic device. The third connecting member 20 achieves the fixed connection of the bottom wall 2 of the liquid storage pot and the hydraulic device, which can support the liquid storage pot to some extent and improve the stability of the bottom of the liquid storage pot. At the same time, the liquid storage pot in this embodiment is provided with connecting members on the side wall 1 and the bottom wall 2, so that the side wall 1 and the bottom wall 2 of the liquid storage pot are connected to the hydraulic device, which helps to improve the connection reliability and stability of the liquid storage pot and the hydraulic device.

[0061] Alternatively, in some embodiments of the present application, the third connecting member 20 extends along the first direction X, and the third connecting member 20 is adapted to achieve the fixed connection of the liquid storage pot and the hydraulic device in the first direction X. Specifically, referring to Figure 1 and Figure 2As shown, the third connecting member 20 is also a connecting hole, and the axis of the connecting hole extends along the first direction X, so that the fastener needs to be arranged in the connecting hole along the first direction X, so that the third connecting member 20 can realize the fixed connection of the liquid storage pot and the hydraulic device in the first direction X. Of course, the third connecting member 20 can also be a connecting shaft, a limiting member, etc., which all extend along the first direction X.

Therefore, through the first connecting member 11, the second connecting member 12 and the third connecting member 20, the fixed connection of the liquid storage pot and the hydraulic device in two directions and two planes can be realized, which helps to further improve the connection reliability and stability of the liquid storage pot and the hydraulic device, provides protection for the communication and sealing of the liquid outlet on the liquid storage pot and the liquid inlet pipeline on the hydraulic device, and reduces the probability of oil leakage between the liquid storage pot and the hydraulic device.

[0063] Optionally, in some embodiments of the present application, the first connecting member 11 is a threaded hole, and / or the second connecting member 12 is a threaded hole, and / or the third connecting member 20 is a threaded hole. That is, at least one of the first connecting member 11, the second connecting member 12 and the third connecting member 20 is a threaded hole, which is connected with a fastener such as a bolt, a screw, etc., which is more helpful to improve the connection reliability and reduce the probability of loosening at the connection site.

[0064] In addition, if the first connecting member 11, the second connecting member 12 and the third connecting member 20 are all connecting holes, the hole diameters of the first connecting member 11, the second connecting member 12 and the third connecting member 20 can be adaptively set according to the size of the connection site on the hydraulic device, so that they can be smoothly connected. The specific size is not limited in the present embodiment. If the first connecting member 11, the second connecting member 12 and the third connecting member 20 are all connecting shafts, limiting members or other ways, their setting principles are similar to those of the connecting holes, which will not be described herein again.

[0065] Optionally, in some embodiments of the present application, the side wall 1 is also provided with a connecting hole 13, and the liquid storage pot further comprises a liquid level sensor 4, and the end of the liquid level sensor 4 is embedded and fixed in the connecting hole 13. Referring to Figure 2As shown, the connecting hole 13 is arranged along the first direction X, and the aperture of the connecting hole 13 is adapted to the size of the liquid level sensor 4, so that part of the liquid level sensor 4 can be smoothly embedded in the connecting hole 13. The liquid level sensor can measure the height of the oil liquid in the liquid storage pot, and is electrically connected with the related control components in the brake system. The control components can feedback the liquid level detected by the liquid level sensor 4 to remind personnel to timely supplement liquid, etc. In addition, the liquid level sensor can be any type of optical liquid level sensor, ultrasonic liquid level sensor, float liquid level sensor, and conductive liquid level sensor, and the present embodiment is not limited thereto.

The sealing ring 41 can be assembled with the connecting hole 13 to realize the sealed connection of the liquid level sensor 4 and the connecting hole 13. The sealing ring 41 can be made of materials such as neoprene, silicone rubber, fluororubber, and nitrile rubber, or can be made of materials such as polyurethane (PU), polyethylene (PE), and polytetrafluoroethylene (PTEE). The above-mentioned materials have excellent corrosion resistance and aging resistance, which helps to maintain the long-term effective sealed connection of the liquid level sensor 4 and the connecting hole 13. In addition, the sealing ring 41 is used in the present embodiment to achieve the sealing effect, which eliminates the plastic packaging process of the liquid level sensor 4 in the traditional way, realizes the process optimization effect, and helps to reduce the sealing cost.

[0067] Figure 3 is a schematic view of the inner chamber of the liquid storage pot in the present embodiment, with reference to Figure 3 In some embodiments of the present application, a partition plate 5 is arranged in the liquid storage pot, which divides the liquid storage pot into a first chamber 61 and a second chamber 62. The partition plate 5 is provided with an opening 50, and the first chamber 61 and the second chamber 62 are communicated through the opening 50. The at least one liquid outlet includes a first liquid outlet 31 and a second liquid outlet 32. The first chamber 61 is communicated with the first liquid outlet 31, and the first chamber 61 is suitable for supplementing liquid to the mechanical brake circuit. The second chamber 62 is communicated with the second liquid outlet 32, and the second chamber 62 is suitable for supplementing liquid to the electric brake circuit.

[0068] Specifically, the liquid storage pot is a hollow structure, and has a cavity inside. A partition plate 5 is arranged in the cavity, and the partition plate 5 divides the cavity into a first cavity 61 and a second cavity 62. An opening 50 is arranged on the partition plate 5, and the first cavity 61 and the second cavity 62 are in communication through the opening 50, so that the oil in the first cavity 61 can flow into the second cavity 62 through the opening 50, and the oil in the second cavity 62 can also flow into the first cavity 61 through the opening 50. The liquid outlet on the side wall 1 of the liquid storage pot includes a first liquid outlet 31 and a second liquid outlet 32. The first cavity 61 is in communication with the first liquid outlet 31, and the oil in the first cavity 61 can flow into the liquid inlet pipeline of the hydraulic device through the first liquid outlet 31. The second cavity 62 is in communication with the second liquid outlet 32, and the oil in the second cavity 62 can flow into the liquid inlet pipeline of the hydraulic device through the second liquid outlet 32. The first cavity 61 and the second cavity 62 are suitable for working in different working conditions.

[0069] Specifically, the first cavity 61 is suitable for supplementing the mechanical brake circuit with oil. The mechanical brake circuit refers to a brake circuit that relies on mechanical force or external physical action to achieve braking, usually through the friction between brake pads and brake discs to generate braking force, or through transmission devices such as ropes and chains. The control is usually manual or mechanical automation, and the driver is required to achieve braking through physical action (such as stepping on the brake pedal or pulling the brake handle), or the braking is automatically triggered by a mechanical transmission system. The second cavity 62 is suitable for supplementing the electric brake circuit with oil. The electric brake circuit is driven by a power-driven device (such as an electromagnet or a servo motor) to achieve braking. The electric brake circuit usually controls the braking force through changes in electric current, and is usually controlled by an electronic control system to control the braking process, such as monitoring vehicle speed, state and other information through sensors and electronic control units (ECU), and adjusting the braking force output of the electric motor as needed. The mechanical brake circuit has low cost and high stability, but the electric brake circuit has faster response speed and can usually achieve more precise control. Therefore, in actual application, the mechanical brake circuit or the electric brake circuit can be flexibly selected and used according to the actual working condition, that is, the oil in the first cavity 61 or the oil in the second cavity 62 is selected to be discharged.

[0070] Optionally, in some embodiments of the present application, a gap is reserved between the opening 50 and the bottom of the liquid storage pot. This ensures the minimum amount of oil in the first cavity 61 and the second cavity 62, and can also prevent the oil from flowing excessively into the adjacent cavity when the liquid storage pot is tilted.

[0071] Optionally, in some embodiments of the present application, the partition 5 comprises a first partition portion 51 and a second partition portion 52; the first partition portion 51 is arranged in the same direction as the liquid outlet directions of the first liquid outlet 31 and the second liquid outlet 32, and the second partition portion 52 is perpendicular to the first partition portion 51; the opening 50 is arranged on the second partition portion 52. The second partition portion 52 is perpendicular to the first partition portion 51, so that the first chamber 61 has an "L" shape structure, which can increase the volume of the first chamber 61 to some extent. At the same time, the first partition portion 51 is arranged in the same direction as the liquid outlet directions of the first liquid outlet 31 and the second liquid outlet 32, so that the dead angle area is not easy to appear, which helps to improve the phenomenon of long-term oil residue forming oil dirt.

[0072] Optionally, in some embodiments of the present application, the liquid storage pot further comprises a third chamber 63, and the third chamber 63 is independent of the first chamber 61 and the second chamber 62; the at least one liquid outlet further comprises a third liquid outlet 33, and the third chamber 63 is in communication with the third liquid outlet 33, and the third chamber 63 is suitable for discharging oil to the travel simulator.

[0073] Specifically, the third chamber 63 is independent of the first chamber 61 and the second chamber 62, that is, the third chamber 63 is not in communication with the first chamber 61 and the second chamber 62, and the liquid outlet on the side wall 1 of the liquid storage pot further comprises a third liquid outlet 33, and the third chamber 63 is in communication with the third liquid outlet 33, and the oil in the third chamber 63 can flow into the liquid inlet pipeline of the hydraulic device through the third liquid outlet 33. The third chamber 63 is suitable for discharging oil to the travel simulator, which is a device or apparatus for simulating or simulating the travel of a brake pedal (or a brake operating component), which can make the driver obtain more realistic feedback in actual driving by simulating the physical action and feeling of the brake pedal. Discharging oil to the travel simulator through the third chamber 63 mainly refers to simulating the hydraulic characteristics of the brake system through the action of the travel simulator in the brake system, and ensuring that there is no air bubble in the oil in the system, or removing the gas and impurities in the system, so as to ensure the normal work of the brake system.

[0074] Therefore, in the present embodiment, the liquid storage pot comprises three chambers, i.e., the first chamber 61, the second chamber 62, and the third chamber 63, and the side wall 1 of the liquid storage pot comprises three liquid outlets, i.e., the first liquid outlet 31, the second liquid outlet 32, and the third liquid outlet 33; the first liquid outlet 31 is in communication with the first chamber 61, the second liquid outlet 32 is in communication with the second chamber 62, and the third liquid outlet 33 is in communication with the third chamber 63; each liquid outlet is in communication with the liquid inlet pipeline of the hydraulic device, thereby forming a complete oil flow path.

[0075] Optionally, in some embodiments of the present application, the volume of the first chamber 61 and the second chamber 62 is greater than the volume of the third chamber 63. Specifically, since the third chamber 63 is suitable for draining the travel simulator, it is only necessary to perform drainage once in a period, and does not need to work frequently, and the capacity required for drainage is small, therefore, by setting the volume of the first chamber 61 and the second chamber 62 to be greater than the volume of the third chamber 63, the working requirement of the third chamber 63 can be met, and the capacity of the first chamber 61 and the second chamber 62 can be increased under the condition that the total capacity of the liquid storage pot is constant, thereby providing guarantee for the functions of the liquid storage pot for supplementing the mechanical brake circuit and the electric brake circuit.

[0076] Optionally, in some embodiments of the present application, the first chamber 61 and the second chamber 62 are respectively provided with reinforcing ribs 7. Specifically, since the volume of the first chamber 61 and the second chamber 62 is large, the first chamber 61 and the second chamber 62 are respectively provided with reinforcing ribs 7, so as to improve the strength and structural stability of the first chamber 61 and the second chamber 62, and avoid the situation that the pot body is expanded and deformed and the surface is whitened when the pressure in the first chamber 61 and the second chamber 62 is too large. In addition, as shown in FIG. 6, the second chamber 62 is provided with a small chamber, and a liquid level signal transmitter is arranged in the small chamber, which is used for monitoring the height of the liquid level, and the small chamber can be arranged in the middle of the pot body, so as to avoid the situation that the liquid level monitoring is inaccurate due to the front and rear inclination of the liquid storage pot. Figure 3

[0077] The present application also provides a brake assembly, Figure 4 is a schematic view of a brake assembly in the embodiments of the present application, referring to Figure 4 , the brake assembly comprises a motor 03, a hydraulic device 02 and a liquid storage pot 01, the liquid storage pot 01 adopts the liquid storage pot described in any one of the preceding embodiments, and the liquid storage pot 01 and the motor 03 are respectively connected with the hydraulic device 02; the liquid outlet direction of the liquid outlet of the side wall 1 of the liquid storage pot 01 is parallel to the axis direction of the hydraulic pump in the hydraulic device 02, and / or the liquid storage pot 01 and the motor 03 are arranged on the same side of the hydraulic device 02.

[0078] Specifically, the hydraulic device 02 comprises a hydraulic pump, a brake caliper, a hydraulic pipeline, a control valve and the like, the liquid inlet pipeline is a part of the hydraulic pipeline, and the hydraulic device utilizes the incompressibility of liquid to transmit force to generate braking force. Among them, the hydraulic pump is used to pump and pressurize the oil in the liquid storage pot, and to convert low-pressure oil into high-pressure oil, and the motor can drive the hydraulic pump to pressurize the oil. The hydraulic pipeline connects each hydraulic component in the brake assembly, and delivers the oil from the liquid storage pot 01 to the hydraulic pump, the caliper and other brake elements. The brake caliper drives the brake pad to press the brake disc by the pressure of the oil, so as to generate friction force, so as to slow down or stop the vehicle. The control valve is used to adjust the flow direction, flow rate and pressure of the oil, and assists in controlling the braking force of the wheels at different positions. ​

[0079] In some embodiments, the liquid outlet of the liquid storage pot 01 is parallel to the axis direction of the hydraulic pump in the hydraulic device 02, that is, the axis direction of the piston in the hydraulic pump, which helps to improve the smoothness of the liquid outlet and thus improves the braking effect of the brake assembly. At the same time, the liquid outlet of the liquid storage pot 01 and the liquid inlet pipeline of the hydraulic device can be connected laterally, so that the liquid storage pot 01 can be installed on the side of the hydraulic device 02 or the side wall of the liquid storage pot 01 is attached to the side of the hydraulic device 02, thereby facilitating the reduction of the space occupied by the liquid storage pot in the height direction of the front cabin and the installation and layout of other components in the front cabin. Alternatively, in some embodiments, the liquid storage pot 01 and the motor 03 are arranged on the same side of the hydraulic device 02, so that the installation of the liquid storage pot 01 reuses the space on the side of the motor 03, thereby further reducing the occupied space of the brake assembly and improving the space utilization of the brake assembly. Alternatively, in some embodiments, the liquid outlet of the liquid storage pot 01 is parallel to the axis direction of the hydraulic pump in the hydraulic device 02, and the liquid storage pot 01 and the motor 03 are also arranged on the same side of the hydraulic device 02, so that the brake assembly can achieve the advantages of smooth liquid outlet and small occupied space, and achieve better effect.
