Description

Technical Field

[0001] The present application relates to the field of automobile brake system components, and in particular to a brake oil tank. Background Art

[0002] In the field of automobile manufacturing, the braking system is a key part to ensure driving safety, and the brake oil tank, as an important component of the braking system, its performance directly affects the reliability and stability of the braking system.

[0003] In related art, a brake fluid reservoir typically includes a reservoir chamber for storing brake fluid, connected to the master cylinder via a pipeline for fluid delivery. The reservoir chamber is configured with a maze-like flow path through partitions. Once the brake fluid enters the reservoir chamber, it slowly flows along the path to the output port, creating a large circulation loop within the reservoir chamber.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when the brake oil in the brake system is insufficient, due to the relatively complex flow channel structure, it takes a long time for the brake oil to flow to the output end, and there is a risk that the brake oil cannot be output to the brake master cylinder in time, affecting the normal operation of the brake system. Summary of the Invention

[0005] In order to improve the problem that the brake oil cannot be discharged in time due to too little oil in the brake oil tank, the present application provides a brake oil tank.

[0006] The present application provides a brake oil tank that adopts the following technical solution: A brake oil pot comprises a brake pot body, wherein a liquid storage chamber for storing brake oil and a diversion chamber arranged on the upper side of the liquid storage chamber are formed inside the brake pot body, and the brake pot body is provided with a diversion plate for separating the liquid storage chamber and the diversion chamber; a return port connected to the diversion chamber and used for arranging the automobile brake pipeline and a liquid injection port for adding liquid to the liquid storage chamber are provided on the top of the brake pot body; a liquid outlet is provided at the bottom of the brake pot body, and a liquid outlet pipe connected to the automobile brake master cylinder is provided at the outer end of the liquid outlet; the diversion plate has a diversion port that passes through the inner and outer surfaces and is used to connect the liquid storage chamber and the diversion chamber, and the brake pot body is provided with a filtering mechanism in the diversion chamber for covering the diversion port; the filtering mechanism comprises a mesh plate assembly vertically slidably arranged on the diversion port and a driving assembly for driving the mesh plate assembly to move.

[0007] By adopting the above technical solution, during the operation of the automobile braking system, the brake master cylinder applies pressure, causing the brake oil to be compressed and generating a flow demand. Under the action of the pressure difference, the brake oil in the liquid storage chamber flows out through the liquid outlet at the bottom of the brake pot body, enters the liquid outlet pipe and is transported to the brake master cylinder to perform the braking function; when the braking action is released or the master cylinder pressure is reduced, the brake oil volume is restored or the system needs to return, and the returned brake oil flows into the guide chamber along the brake pipeline connected to the return port, and flows to the guide port under the guidance of the guide plate. At this time, the mesh plate assembly located at the guide port filters the brake oil, intercepts solid impurities and separates retained bubbles. The filtered and purified brake oil is re-entered into the reservoir chamber through the diversion port, completing the brake oil circulation loop; when the brake oil level in the reservoir chamber is insufficient, in order to ensure the braking response speed, the drive assembly reservoir chamber and the mesh assembly are driven to be lifted vertically. After the mesh plate is lifted, a bypass channel is formed at the diversion port, so that the return brake oil can be directly and quickly injected into the reservoir chamber without being filtered by the mesh assembly, thereby realizing emergency replenishment of the oil volume in the reservoir chamber; if the total brake oil volume of the entire brake system is insufficient due to leakage or consumption, the operator can add brake oil to the brake pot body through the filling port above the brake pot body to maintain the normal working fluid level of the system.

The inclined arrangement of the guide plate helps to increase the flow rate of the brake oil; the square cross-section of the guide port helps to improve the adaptability with the mesh plate assembly, which helps to install and move the mesh plate assembly; the limit plate can circumferentially limit the mesh plate assembly, which helps to reduce the risk of displacement of the mesh plate assembly during the vertical lifting process driven by the drive assembly, thereby helping to improve the operating stability of the filtering mechanism.

[0010] Optionally, the mesh panel assembly includes a mounting bracket, a filter screen arranged on the top of the mounting bracket, a sealing ring arranged on the outer edge of the filter screen, and a diversion baffle installed on both sides of the mounting bracket and extending away from the diversion chamber; the mounting bracket has a mounting seat in the middle, and the filter screen has a mounting groove in the middle that cooperates with the mounting seat.

[0011] By adopting the above technical solution, the specific structure of the mesh plate assembly is disclosed. The combination of the mounting bracket, the filter screen, the sealing ring and the guide baffle is used to make the structure of the mesh plate assembly more stable. The filter screen and the mounting seat are installed in conjunction with the mounting groove, which facilitates the installation and disassembly of the filter screen, helps to clean and replace the filter screen during subsequent use, and helps to improve the durability of the mesh plate assembly; the sealing ring helps to improve the installation firmness between the filter screen and the mounting seat, and helps to reduce the risk of brake oil leakage; the guide baffle can cooperate with the limit plate to guide the brake oil to flow to the liquid storage chamber.

[0012] Optionally, the drive assembly includes a drive screw arranged vertically and connected to the mounting bracket at one end, a screw nut mounted on the mounting bracket and adapted to the drive screw, and a drive motor driving the drive screw to rotate; a mounting hole is opened in the middle of the mounting seat, which passes through the inner and outer surfaces and is used for arranging the screw nut.

[0013] By adopting the above technical solution, the specific structure of the drive assembly is disclosed. The drive motor drives the drive screw to rotate, and the screw nut and the drive screw are adapted to drive the mounting bracket to move, so that the mesh plate assembly can slide vertically in the guide chamber, thereby realizing the closing and opening of the guide port by the mesh plate assembly, which helps to filter the brake oil and control its flow.

[0014] Optionally, the liquid outlet pipe is arranged obliquely downward in a direction away from the liquid outlet port, and an angle formed by an axis of the liquid outlet pipe and the brake oil level is 5-15°.

[0015] By adopting the above technical solution, the liquid outlet pipe is arranged downward at an angle of 5-15 degrees to the brake oil level, so that the brake oil flows more smoothly from the brake oil tank into the brake master cylinder by gravity, reducing the adhesion and residue of the brake oil in the liquid outlet pipe, which helps to improve the output efficiency of the brake oil.

[0016] Optionally, the brake pot body is provided with a guide groove at the front end of the liquid outlet, and the guide outlet is arranged opposite to the guide groove.

[0020] Optionally, a first abutment column for abutting the upper end face of the liquid level float is provided at the bottom of the guide plate; and a second abutment column arranged opposite to the first abutment column and for abutting the lower end face of the liquid level float is provided at the bottom of the liquid storage chamber of the brake pot body.

[0021] By adopting the above technical solution, the first abutment column and the second abutment column can limit the vertical movement range of the liquid level float, so that the liquid level float rises and falls stably with the liquid level; when the brake oil in the liquid storage chamber is at or above the highest liquid level line, the upper end face of the liquid level float abuts against the lower end face of the first abutment column; when the brake oil in the liquid storage chamber is at or below the lowest liquid level line, the lower end face of the liquid level float abuts against the lower end face of the second abutment column.

[0025] By adopting the above technical solution, the annular baffle and the guide plate form a first channel, and are connected to the liquid storage chamber through the first through groove, so that the brake oil can flow more smoothly between the liquid storage chamber and the first channel, reducing the retention of brake oil in local areas, and helping to improve the fluidity and distribution uniformity of the brake oil in the brake pot body.

[0048] The implementation principle of a brake oil pot in the embodiment of the present application is as follows: during the operation of the automobile braking system, the brake master cylinder applies pressure, causing the brake oil to be compressed and generating a flow demand. Under the action of the pressure difference, the brake oil in the liquid storage chamber 14 flows out through the liquid outlet 121 at the bottom of the brake pot body 1, enters the liquid outlet pipe 122 and is transported to the brake master cylinder to perform the braking function; when the braking action is released or the master cylinder pressure is reduced, the brake oil volume is restored or the system needs to return, and the returned brake oil flows into the guide chamber 13 along the brake pipeline connected to the return liquid port 113, and flows to the guide port 1121 under the guidance of the guide plate 112. At this time, the mesh at the guide port 1121 The plate assembly 21 filters the brake oil, intercepts solid impurities and separates retained bubbles, and the filtered and purified brake oil is re-entered into the liquid storage chamber 14 through the guide port 1121, completing the brake oil circulation loop; when the brake oil level in the liquid storage chamber 14 is insufficient, in order to ensure the braking response speed, the drive assembly 22 drives the mesh plate assembly 21 to lift vertically. After the mesh plate is lifted, the lower end of the guide baffle 214 is aligned with the upper edge of the guide port 1121, and a bypass channel is formed at the guide port 1121, so that the return brake oil can be directly and quickly injected into the liquid storage chamber 14 without being filtered by the mesh plate assembly 21, thereby realizing emergency replenishment of the oil volume in the liquid storage chamber 14.
