[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] The terms "first", "second", etc. 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 interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0044] It should be understood that the reference to "some embodiments" throughout the specification means that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the present application. Therefore, the "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] The following describes in detail a fluid storage pot, a brake assembly and a vehicle provided by the present application by listing specific embodiments.

[0046] The embodiment of the present application provides a liquid storage pot, Figure 1 is a schematic diagram of the front and side of a liquid storage pot in an embodiment of the present application, Figure 2 is a schematic diagram of the back side of a liquid storage pot in the embodiment of the present application, referring to Figure 1 and Figure 2 The liquid storage pot has a side wall 1, and at least one liquid outlet is arranged on the side wall 1. The liquid outlet is suitable for connecting with the liquid inlet pipeline of the hydraulic device.

[0047] Specifically, refer to Figure 1 As shown, the liquid storage pot has a first direction X, a second direction Z and a third direction Y, and 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 perpendicular to each other, where "perpendicular" not only includes the absolutely perpendicular situation, but also includes the generally known perpendicular situation, such as the state where the angles between the first direction X, the second direction Z and the third direction Y are 89° to 91°, which are all regarded as the first direction X, the second direction Z and the third direction Y being perpendicular to each other. In this embodiment, the first direction X can be regarded as the width direction of the liquid storage pot, the second direction Z can be regarded as the height direction of the liquid storage pot, and the third direction Y can be regarded as the length direction of the liquid storage pot.

[0048] The liquid reservoir has a side wall 1, which is located in the plane where the second direction Z and the third direction Y are located. The two surfaces of the liquid reservoir that are arranged opposite to each other along the first direction X are both regarded as the side wall 1 of the liquid reservoir. At least one liquid outlet is provided on the side wall 1, which is suitable for the oil stored in the liquid reservoir to flow out. The oil stored in the liquid reservoir is brake fluid, which plays the functions of energy transmission, heat dissipation, lubrication, corrosion prevention and rust prevention in the brake system. The liquid outlet on the liquid reservoir is suitable for connection with the liquid inlet pipeline of the hydraulic device. When the driver steps on the brake pedal, the hydraulic device draws the brake fluid from the liquid reservoir, and the brake fluid reaches the hydraulic device through the liquid outlet and is transmitted to the brake assembly (such as the brake caliper), thereby generating braking force and realizing the braking of the wheel. During the braking process, the brake fluid circulates continuously in the brake system.

[0049] In addition, the liquid outlet is arranged on the side wall 1, and the liquid outlet direction of the liquid outlet intersects with 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 with the side wall 1. For example, the angle between the extension direction of the liquid outlet and the side wall 1 can be 60° to 120°, within which the lateral liquid discharge of the liquid storage pot can be achieved, and the situation of oil blocking the liquid outlet can be reduced. Of course, in actual applications, the 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 to ensure that the liquid outlet can be reliably connected to the liquid inlet pipeline. In some embodiments, the angle between the extension direction of the liquid outlet and the side wall 1 is set to 90°, which is more convenient for the processing of the liquid outlet and the assembly connection of the liquid outlet and the liquid inlet pipeline.

[0050] In the embodiment of the present application, the liquid outlet is arranged on the side wall 1 of the liquid storage pot, so that the liquid discharge method of the liquid storage pot is lateral discharge, that is, the liquid outlet on the liquid storage pot and the liquid inlet pipeline on the hydraulic device can be connected laterally, so that the liquid storage pot can be installed on the side of the hydraulic device, which is beneficial to reduce the space occupied by the liquid storage pot in the height direction of the front cabin, and is more convenient for the installation and layout of other components in the front cabin.

The connecting piece may also be a protrusion, a groove, a hook, etc., so that the liquid reservoir and the hydraulic device are clamped together through the connecting piece. The specific type of the connecting piece is not limited in this embodiment. Therefore, in this embodiment, the liquid reservoir is installed on the side of the hydraulic device through the connecting piece on the side wall 1, which is conducive to reducing the space occupied by the liquid reservoir in the height direction of the front cabin, and is more convenient for the installation and layout of other components in the front cabin.

Of course, the second connecting member 12 can also be a connecting shaft, a stopper, etc., which can be extended along the second direction Z.

[0054] In combination with the foregoing embodiment, the connecting member on the side wall 1 includes a first connecting member 11 and a second connecting member 12. The first connecting member 11 can realize a fixed connection between the liquid reservoir and the hydraulic device in a first direction X, and the second connecting member 12 can realize a fixed connection between the liquid reservoir and the hydraulic device in a second direction Z. Thus, through the first connecting member 11 and the second connecting member 12, a fixed connection between the liquid reservoir and the hydraulic device in two directions can be realized, which is helpful to improve the connection reliability and stability between the liquid reservoir and the hydraulic device, provide a guarantee for the connection and sealing between the liquid outlet on the liquid reservoir and the liquid inlet pipeline on the hydraulic device, and reduce the probability of oil leakage between the liquid reservoir and the hydraulic device.

[0056] Specifically, the liquid storage pot further comprises a bottom wall 2 and a top wall, the bottom wall 2 and the top wall are arranged opposite to each other along the second direction Z, the bottom wall 2 and the top wall are adjacent to the side wall 1, and 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 As shown, the first connecting member 11 is arranged on the side close to the bottom wall 2, and the second connecting member 12 is arranged on the 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 helps to improve the phenomenon of stress concentration at the connection part, and further improves the connection reliability and stability between the liquid storage pot and the hydraulic device. Of course, the first connecting member 11 can also be arranged on the side close to the top wall, and the second connecting member 12 can be arranged on the side close to the bottom wall 2 accordingly.

[0057] Alternatively, in some embodiments, the first connecting member 11 and the second connecting member 12 are disposed on 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 on the left side of the side wall 1, and the second connecting member 12 is arranged on the right side of the side wall 1, so that the first connecting member 11 and the second connecting member 12 can be distributed more dispersedly on the side wall 1, thereby improving the connection reliability and stability between the liquid storage pot and the hydraulic device. Of course, the first connecting member 11 can also be arranged on the right side of the side wall 1, and the second connecting member 12 can be arranged on the left side of the side wall 1 accordingly, which can be specifically arranged according to actual needs, and this embodiment is not limited to this.

[0067] Figure 3 is a schematic diagram of an inner chamber of a liquid storage pot in an embodiment of the present application, referring to Figure 3 In some embodiments of the present application, a partition 5 is provided in the liquid storage pot, and the partition 5 divides the liquid storage pot into a first chamber 61 and a second chamber 62; an opening 50 is provided on the partition 5, and the first chamber 61 is connected to the second chamber 62 through the opening 50; at least one liquid outlet includes a first liquid outlet 31 and a second liquid outlet 32, the first chamber 61 is connected to the first liquid outlet 31, and the first chamber 61 is suitable for replenishing the mechanical brake circuit; the second chamber 62 is connected to the second liquid outlet 32, and the second chamber 62 is suitable for replenishing the electric brake circuit.

[0068] Specifically, the liquid storage pot is a hollow structure, and has a chamber inside. A partition 5 is provided in the chamber, and the partition 5 divides the chamber into a first chamber 61 and a second chamber 62. An opening 50 is provided on the partition 5. The first chamber 61 and the second chamber 62 are connected through the opening 50, so that the oil in the first chamber 61 can flow into the second chamber 62 through the opening 50, and the oil in the second chamber 62 can also flow into the first chamber 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 chamber 61 is connected to the first liquid outlet 31, and the oil in the first chamber 61 can flow into the liquid inlet pipeline of the hydraulic device through the first liquid outlet 31. The second chamber 62 is connected to the second liquid outlet 32, and the oil in the second chamber 62 can flow into the liquid inlet pipeline of the hydraulic device through the second liquid outlet 32. Among them, the first chamber 61 and the second chamber 62 are suitable for working under different working conditions.

[0069] Specifically, the first chamber 61 is suitable for replenishing fluid in the mechanical brake circuit. The mechanical brake circuit refers to a circuit that achieves braking by mechanical force or external physical action, usually generating braking force through the friction between the brake pad and the brake disc, or through a transmission device such as a rope or chain. Its control is usually manual or mechanically automated, requiring the driver to achieve braking through physical action (such as stepping on the brake pedal, pulling the brake handle, etc.), or automatically triggering braking through a mechanical transmission system. The second chamber 62 is suitable for replenishing fluid in the electric brake circuit. The electric brake circuit achieves braking by an electric drive device (such as an electromagnet, a servo motor, etc.). The electric brake circuit usually controls the braking force through changes in current. The braking process is usually controlled by an electronic control system, such as using sensors and electronic control units (ECUs) to monitor vehicle speed, status and other information, and adjust the braking force output of the motor as needed. The mechanical brake circuit has lower cost and higher stability, but the electric brake circuit has a faster response speed and can usually achieve more precise control. Therefore, in actual applications, you can flexibly choose to use either the mechanical brake circuit or the electric brake circuit based on the actual working conditions, that is, you can flexibly choose to output oil from the first chamber 61 or the second chamber 62.

[0070] Optionally, in some embodiments of the present application, a distance is reserved between the opening 50 and the bottom of the liquid storage pot to ensure the minimum amount of oil in the first chamber 61 and the second chamber 62, and to prevent excessive oil from flowing into adjacent chambers when the liquid storage pot is tilted.

[0071] Optionally, in some embodiments of the present application, the partition 5 includes a first baffle 51 and a second baffle 52; the first baffle 51 is arranged in the same direction as the liquid outlet direction of the first liquid outlet 31 and the second liquid outlet 32, and the second baffle 52 is perpendicular to the first baffle 51; the opening 50 is arranged on the second baffle 52. The second baffle 52 is perpendicular to the first baffle 51, so that the first chamber 61 is in an "L"-shaped structure, which can increase the volume of the first chamber 61 to a certain extent. At the same time, the first baffle 51 is arranged in the same direction as the liquid outlet direction of the first liquid outlet 31 and the second liquid outlet 32, so that dead corners are not likely to appear, which helps to improve the phenomenon of oil stains formed by long-term residual oil.

[0072] Optionally, in some embodiments of the present application, a third chamber 63 is further provided in the liquid storage pot, and the third chamber 63 is independent of the first chamber 61 and the second chamber 62; at least one liquid outlet also includes a third liquid outlet 33, and the third chamber 63 is connected to the third liquid outlet 33, and the third chamber 63 is suitable for draining the stroke 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 connected to the first chamber 61 and the second chamber 62, and the liquid outlet on the side wall 1 of the liquid reservoir also includes a third liquid outlet 33, and the third chamber 63 is connected to 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 draining the stroke simulator, and the stroke simulator is a device or device used to simulate or simulate the stroke of the brake pedal (or brake operating component), which simulates the physical movement and feeling of the brake pedal to enable the driver to obtain more realistic feedback in actual driving. Draining the stroke simulator through the third chamber 63 mainly refers to simulating the hydraulic characteristics of the brake system through the action of the stroke simulator in the brake system, and ensuring that there are no bubbles in the oil in the system, or clearing the gas and impurities in the system, so as to ensure the normal operation of the brake system.

[0074] Thus, the liquid storage pot in this embodiment is provided with three chambers, namely the first chamber 61, the second chamber 62, and the third chamber 63, and the side wall 1 of the liquid storage pot is provided with three liquid outlets, namely the first liquid outlet 31, the second liquid outlet 32, and the third liquid outlet 33. The first liquid outlet 31 is connected with the first chamber 61, the second liquid outlet 32 ​​is connected with the second chamber 62, and the third liquid outlet 33 is connected with the third chamber 63. Each liquid outlet is respectively connected 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 stroke simulator, it only needs to be drained once regularly, does not need to work frequently, and the capacity required for draining is small, so the volume of the first chamber 61 and the second chamber 62 is set to be greater than the volume of the third chamber 63, which can not only meet the working requirements of the third chamber 63, but also increase the capacity of the first chamber 61 and the second chamber 62 when the total volume of the reservoir is constant, so as to provide a guarantee for the reservoir's function of replenishing the mechanical brake circuit and the electric brake circuit.

[0076] Optionally, in some embodiments of the present application, reinforcing ribs 7 are respectively provided in the first chamber 61 and the second chamber 62. Specifically, since the volumes of the first chamber 61 and the second chamber 62 are relatively large, reinforcing ribs 7 are respectively provided in the first chamber 61 and the second chamber 62 to enhance the strength and structural stability of the first chamber 61 and the second chamber 62, and to prevent the kettle body from expanding and deforming and causing the surface to turn white when the pressure in the first chamber 61 and the second chamber 62 is too high. In addition, referring to Figure 3 As shown, a small chamber is provided in the second chamber 62, and a liquid level signal transmitter is provided in the small chamber. The liquid level signal transmitter is used to monitor the height of the liquid level. At the same time, the small chamber can be arranged in the middle of the kettle body to avoid the liquid storage kettle tilting forward and backward, resulting in inaccurate liquid level monitoring.

[0077] The embodiment of the present application also provides a brake assembly, Figure 4 is a schematic diagram of a brake assembly in an embodiment of the present application, referring to Figure 4 The brake assembly includes a motor 03, a hydraulic device 02 and a fluid reservoir 01. The fluid reservoir 01 adopts the fluid reservoir described in any of the aforementioned embodiments. The fluid reservoir 01 and the motor 03 are respectively connected to the hydraulic device 02; the fluid outlet direction of the fluid outlet on the side wall 1 of the fluid reservoir 01 is parallel to the axial direction of the hydraulic pump in the hydraulic device 02, and / or the fluid reservoir 01 and the motor 03 are arranged on the same side of the hydraulic device 02.

[0078] Specifically, the hydraulic device 02 includes a hydraulic pump, a brake caliper, a hydraulic pipeline, a control valve, etc. The liquid inlet pipeline is part of the hydraulic pipeline. The hydraulic device uses the incompressibility of the liquid to transmit force and generate braking force. Among them, the hydraulic pump is used to pump and pressurize the oil in the reservoir, converting the low-pressure oil into high-pressure oil, and the motor can drive the hydraulic pump to pressurize the oil. The hydraulic pipeline connects the various hydraulic components in the brake assembly and transports the oil from the reservoir 01 to the hydraulic pump, caliper and other brake elements. The brake caliper drives the brake pad to press the brake disc through the pressure of the oil, thereby generating friction to slow down or stop the vehicle. The control valve is used to adjust the flow direction, flow rate and pressure of the oil to help control the braking force of wheels in different positions.

[0079] In some embodiments, the liquid outlet direction of the liquid reservoir 01 is parallel to the axial direction of the hydraulic pump in the hydraulic device 02, the axial direction of the hydraulic pump is the axial direction of the piston in the hydraulic pump, and the liquid outlet direction of the liquid reservoir is parallel to the axial direction of the piston, which helps to improve the smoothness of the liquid outlet, thereby improving the braking effect of the brake assembly to a certain extent. At the same time, the liquid outlet on the liquid reservoir 01 can be connected laterally with the liquid inlet pipeline on the hydraulic device, so that the liquid reservoir 01 can be installed on the side of the hydraulic device 02 or the side wall of the liquid reservoir 01 fits the side of the hydraulic device 02, which is conducive to reducing the space occupied by the liquid reservoir in the height direction of the front cabin, and is more convenient for the installation and layout of other components in the front cabin. Alternatively, in some embodiments, the liquid reservoir 01 and the motor 03 are arranged on the same side of the hydraulic device 02, so that the installation of the liquid reservoir 01 reuses the space on the side of the motor 03, which helps to further reduce the occupied space of the brake assembly and improve the space utilization rate of the brake assembly. Alternatively, in some embodiments, the liquid discharge direction of the liquid outlet on the liquid storage pot 01 is parallel to the axial 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 discharge and small space occupation at the same time, achieving better results.

[0080] An embodiment of the present application also provides a vehicle, including a fluid reservoir and a brake assembly, wherein the fluid reservoir adopts the fluid reservoir described in any of the aforementioned embodiments, and the brake assembly adopts the brake assembly of the aforementioned embodiments, so as to enhance the braking capability of the vehicle, thereby enhancing the safety performance of the vehicle.
