Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic brake pump technology, and in particular to a brake pump. Background Technology
[0002] Pumps, as general-purpose machines widely used in various industries, have evolved into diverse structural forms and types based on different dimensions such as applicable fields, functional requirements, and working media. The hydraulic brake pump of an unmanned tractor is the core actuator of its braking system. Its working principle involves receiving control signals from the electronic control system and converting these signals into controllable and stable hydraulic pressure through its internal structure. This pressure drives the brake cylinder to extend and retract, thereby completing the parking brake and release operation of the tractor. This directly relates to the safety and operational stability of the unmanned tractor.
[0003] Existing brake pumps mainly consist of a motor, a valve block, and an oil tank. The valve block has an oil inlet that connects to the oil tank, and an internal channel connecting the oil tank and the oil inlet. Hydraulic oil is injected into the oil tank through this inlet and channel. Due to space constraints, this channel is usually designed with right angles, making it difficult for the oil filling pipe to extend into the oil tank. During the filling process, the hydraulic oil can easily seal off the channel, making it difficult for gas to escape from the oil tank, thus causing filling difficulties.
[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content
[0005] The purpose of this invention is to solve the problem of difficult oil filling in brake pumps in the prior art, and to propose a brake pump accordingly.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: A brake pump includes an oil reservoir, an integrated base, and a motor. The extension direction of the oil reservoir is defined as a first direction. Along the first direction, the integrated base has a first end and a second end facing away from each other. The motor is disposed at the first end, and the output shaft of the motor extends into the integrated base. The oil reservoir is disposed at the second end, and a gear pump is disposed within the oil reservoir. The input shaft of the gear pump is drively connected to the output shaft of the motor. The first end of the integrated base has an oil inlet. The integrated base has a first oil delivery pipe for connecting the oil inlet and the oil reservoir. The peripheral sidewall of the integrated base has a first oil port and a second oil port. The first oil port communicates with the oil outlet of the gear pump, and the second oil port communicates with the oil reservoir. The second oil port also serves as the vent port of the oil reservoir.
[0007] Furthermore, the second oil port is connected to the oil storage tank through the second oil pipeline, and a third oil pipeline is provided between the first oil port and the second oil pipeline. A solenoid valve is provided on the third oil pipeline, and the solenoid valve is used to control the opening and closing of the third oil pipeline.
[0008] Furthermore, in the first direction, the position of the oil inlet is higher than that of the second oil inlet.
[0009] Furthermore, the integrated base is provided with a fourth oil supply pipe for connecting the first oil port and the oil outlet of the gear pump. The fourth oil supply pipe is provided with a one-way valve, which ensures that hydraulic oil can only flow from the oil outlet of the gear pump to the first oil port.
[0010] Furthermore, an overflow valve is provided between the oil outlet of the gear pump and the check valve.
[0011] Furthermore, an oil pressure sensor is installed on the fourth oil pipeline.
[0012] Furthermore, an oil temperature sensor is installed on the third oil pipeline.
[0013] Furthermore, the peripheral sidewall of the integrated base is provided with a pressure measuring port, which is connected to the third oil pipeline.
[0014] Furthermore, the second end of the integrated base is provided with a first oil inlet, which is connected to the oil filling port through a first oil supply pipe; on the projection plane perpendicular to the first direction, the projection of the outer wall of the gear pump coincides with the projection of the first oil inlet.
[0015] Furthermore, the second end of the integrated base is provided with a second oil inlet, which is connected to the second oil port through a second oil delivery pipe; on the projection plane perpendicular to the first direction, the projection of the outer wall of the gear pump coincides with the projection of the second oil inlet.
[0016] The beneficial effects of this utility model after adopting the above structure are as follows: (1) The brake pump of this utility model includes an oil reservoir, an integrated base, and a motor. The first end of the integrated base is provided with an oil inlet. The integrated base has a first oil supply pipe inside for connecting the oil inlet and the oil reservoir. The peripheral sidewall of the integrated base is provided with a first oil port and a second oil port. The first oil port is connected to the outlet of the gear pump, and the second oil port is connected to the oil reservoir through a second oil supply pipe. The second oil port also serves as the vent port of the oil reservoir. In this utility model, the first oil port is a high-pressure port, and the second oil port is a low-pressure port. The second oil port also serves as the vent port when the oil reservoir is filled with oil. When oil is injected into the oil reservoir through the oil inlet, the gas inside the oil reservoir is discharged from the second oil port, which facilitates the smooth injection of hydraulic oil and allows for accurate judgment of whether the oil reservoir is full of hydraulic oil by observing whether hydraulic oil flows out of the second oil port. Using the second oil port as a vent port not only simplifies the processing technology and saves production costs but also reduces the risk of oil leakage.
[0017] (2) In the brake pump described in this utility model, the extension direction of the oil reservoir is defined as a first direction. Along the first direction, the integrated base has a first end and a second end facing away from each other. The motor is disposed at the first end, and the output shaft of the motor extends into the interior of the integrated base. The oil reservoir is disposed at the second end. This utility model adopts a vertical installation, and the oil reservoir is located at the bottom, which reduces the risk of oil leakage at the connection between the oil reservoir and the integrated base. Furthermore, the vertical installation structure design can also prevent the hydraulic oil in the oil reservoir from seeping into electronic components such as the motor, thus avoiding problems such as poor contact and poor heat dissipation caused by hydraulic oil seeping into electronic components from the source, which is conducive to improving the stability of the brake pump operation.
[0018] (3) The brake pump described in this utility model integrates the solenoid valve, check valve, overflow valve, oil pressure sensor, and oil temperature sensor into an integrated base, and the integrated base is provided with an oil supply pipe for connecting the various components. This highly integrated design not only reduces the number of pipes and connectors used, simplifies the assembly process, and reduces the risk of assembly errors; at the same time, the compact integrated structure effectively reduces the overall space occupied by the product, avoids conflicts with the installation space of other hydraulic components and electronic control modules, perfectly meets the needs of unmanned tractors for compact and integrated layout, and fully meets the core usage requirements of efficient operation and precise control of the braking system in unmanned driving scenarios.

[0029] like Figures 1 to 9As shown, a brake pump includes an oil reservoir 1, an integrated base 2, and a motor 3. The extension direction of the oil reservoir 1 is defined as a first direction. Along the first direction, the integrated base 2 has a first end and a second end facing away from each other. The motor 3 is disposed at the first end, and the output shaft 31 of the motor 3 extends into the interior of the integrated base 2. The oil reservoir 1 is disposed at the second end, and a gear pump 4 is disposed inside the oil reservoir 1. The input shaft 41 of the gear pump 4 is drively connected to the output shaft 31 of the motor 3. An oil inlet 21 is disposed at the first end of the integrated base 2. A first oil delivery pipe 10 for connecting the oil inlet 21 and the oil reservoir 1 is disposed inside the integrated base 2. A first oil port 22 and a second oil port 23 are disposed on the peripheral sidewall of the integrated base 2. The first oil port 22 is connected to the oil outlet of the gear pump 4, and the second oil port 23 is connected to the oil reservoir 1. The second oil port 23 also serves as the exhaust port of the oil reservoir 1.
[0030] Based on the above embodiments, this utility model provides a brake pump, including an oil reservoir 1, an integrated base 2, and a motor 3. The first end of the integrated base 2 is provided with an oil inlet 21. The integrated base 2 has a first oil supply pipe 10 inside for connecting the oil inlet 21 and the oil reservoir 1. The peripheral sidewall of the integrated base 2 is provided with a first oil port 22 and a second oil port 23. The first oil port 22 is connected to the oil outlet of a gear pump 4, and the second oil port 23 is connected to the oil reservoir 1 through a second oil supply pipe 20. The second oil port 23 also serves as the vent port of the oil reservoir 1. In this utility model, the first oil port 22 is a high-pressure oil port, and the second oil port 23 is a low-pressure oil port. The second oil port 23 also serves as the vent port when the oil reservoir 1 is filled with oil. When oil is injected into the oil reservoir 1 through the oil inlet 21, the gas inside the oil reservoir 1 is discharged from the second oil port 23, which facilitates the smooth injection of hydraulic oil and allows for accurate judgment of whether the oil reservoir 1 is full of hydraulic oil by observing whether hydraulic oil flows out of the second oil port 23. Using the second oil port 23 as a vent not only simplifies the manufacturing process and saves production costs, but also effectively reduces the risk of oil leakage by reducing the number of joints. In specific application scenarios, when oil is being injected into the oil storage tank 1 through the oil filling port 21, the connecting pipe at the second oil port 23 is disconnected, allowing the oil storage tank 1 to communicate with the outside atmosphere through the second oil port 23. After the oil filling is completed, the connecting pipe is then reinstalled to the second oil port 23 without affecting its normal function. The first direction refers to the height direction of the oil storage tank 1, such as... Figure 3 As shown.
[0031] In this embodiment, the extending direction of the oil storage tank 1 is defined as the first direction. Along the first direction, the integrated base 2 has a first end and a second end facing away from each other. The motor 3 is disposed at the first end, and the output shaft 31 of the motor 3 extends into the interior of the integrated base 2; the oil storage tank 1 is disposed at the second end. Figure 1As shown, the vertical installation with the oil tank 1 located at the bottom reduces the risk of oil leakage at the connection between the oil tank 1 and the integrated base 2. Furthermore, the vertical installation design also prevents the hydraulic oil in the oil tank 1 from seeping into electronic components such as the motor 3, thus avoiding problems such as poor contact and poor heat dissipation caused by hydraulic oil seeping into electronic components from the source, which is conducive to improving the stability of the brake pump operation.
[0032] In this embodiment, the solenoid valve 5, check valve 6, overflow valve 7, oil pressure sensor 8, and oil temperature sensor 9 are all integrated into the integrated base 2, and the integrated base 2 is provided with oil supply pipes for connecting the various components. This highly integrated design not only reduces the number of pipes and connectors used, simplifies the assembly process, and reduces the risk of assembly errors; at the same time, the compact integrated structure effectively reduces the overall space occupied by the product, avoids conflicts with the installation space of other hydraulic components and electronic control modules, perfectly meets the requirements of unmanned tractors for compact and integrated layout, and fully satisfies the core usage requirements of efficient operation and precise control of the braking system in unmanned driving scenarios.
[0033] In this embodiment, the oil inlet 21 extends along the first direction, allowing the hydraulic oil to flow more smoothly into the oil storage tank 1 by its own weight. A first plug 211 is provided on the oil inlet 21. When oil needs to be injected into the oil storage tank 1 through the oil inlet 21, the first plug 211 is removed, the oil inlet 21 is opened, and after the oil injection is completed, the first plug 211 is installed back onto the oil inlet 21 to seal it, ensuring the airtightness of the oil storage tank 1.
[0034] In this embodiment, the motor 3 is a micro motor to reduce the overall space occupied by the brake pump. The motor 3 is equipped with a power input pin 32, and the connection between the power input pin 32 and the docking part is waterproof. During connection, the power input pin 32 is completely housed inside the docking part, achieving waterproof function and preventing short circuits when the unmanned tractor is working outdoors. The input shaft 41 of the gear pump 4 and the output shaft 31 of the motor 3 are connected by a coupling 311. The transmission connection through the coupling 311 takes into account both transmission stability and installation adaptability. The coupling 311 can absorb transmission shock and vibration to ensure smooth operation of the equipment, and can adapt to the installation deviation of the two shafts, reducing the assembly accuracy requirements.
[0035] In another preferred embodiment of this utility model, the second oil port 23 is connected to the oil storage tank 1 via the second oil pipeline 20, and a third oil pipeline 30 is provided between the first oil port 22 and the second oil pipeline 20. A solenoid valve 5 is installed on the third oil pipeline 30, and the solenoid valve 5 is used to control the opening and closing of the third oil pipeline 30. In this embodiment, as... Figure 7As shown, when the solenoid valve 5 is energized, the third oil supply pipe 30 is closed, preventing hydraulic oil from the external hydraulic system from flowing back from the first port 22. When the solenoid valve 5 is de-energized, the third oil supply pipe 30 opens, allowing hydraulic oil from the external hydraulic system to flow back from the first port 22. The third oil supply pipe 30 is also connected to the second port 23 via the second oil supply pipe 20, meaning the hydraulic oil flowing back from the first port 22 can flow out from the second port 23. In a specific application scenario, the first port 22 of the brake pump is connected to the rod chamber of the brake cylinder, and the second port 23 is connected to the rodless chamber of the brake cylinder. When the solenoid valve 5 is de-energized, the hydraulic oil in the rod chamber of the brake cylinder flows into the rodless chamber of the brake cylinder from the first port 22, the third oil supply pipe 30, the second oil supply pipe 20, and the second port 23.
[0036] In another preferred embodiment of this utility model, in the first direction, the position of the oil inlet 21 is higher than that of the second oil inlet 23. In this embodiment, as... Figure 1 As shown, this structure is designed to limit the maximum oil level in oil storage tank 1.
[0037] As another preferred embodiment of this utility model, the integrated base 2 is provided with a fourth oil supply pipe 40 for connecting the first oil port 22 and the oil outlet of the gear pump 4. A one-way valve 6 is provided on the fourth oil supply pipe 40, which ensures that hydraulic oil can only flow from the oil outlet of the gear pump 4 to the first oil port 22. In this embodiment, as... Figure 8 As shown, the one-way valve 6 is designed to prevent hydraulic oil from flowing back to the gear pump 4.
[0038] As another preferred embodiment of this utility model, an overflow valve 7 is provided between the oil outlet of the gear pump 4 and the one-way valve 6. In this embodiment, as... Figure 8 As shown, when the pressure of the external hydraulic system is greater than the set pressure, the working hydraulic oil will not enter the first oil port 22 through the check valve 6, but will flow back directly to the oil storage tank 1 through the relief valve 7, thus avoiding the problem of damage to the external hydraulic system caused by excessive pressure.
[0039] As another preferred embodiment of this utility model, an oil pressure sensor 8 is provided on the fourth oil pipeline 40. In this embodiment, as... Figure 6 As shown, the hydraulic oil pressure output by the gear pump 4 is detected by the oil pressure sensor 8. In a specific application scenario, the brake pump is connected to the brake cylinder, and the oil pressure sensor 8 can detect the oil pressure input to the brake cylinder. This parameter is used to control whether the motor 3 works, ensuring the normal operation of the braking system.
[0040] As another preferred embodiment of this utility model, an oil temperature sensor 9 is provided on the third oil pipeline 30. In this embodiment, as... Figure 7As shown, the oil temperature sensor 9 detects the oil temperature of the hydraulic oil returning from the external hydraulic system of the brake, so as to detect abnormalities in the parking brake system in a timely manner. This allows users to stop the vehicle for inspection and maintenance in a timely manner when abnormalities occur in the parking brake system, which is beneficial to the protection of the system.
[0041] As another preferred embodiment of this utility model, a pressure measuring port 24 is provided on the peripheral sidewall of the integrated base 2, and the pressure measuring port 24 is connected to the third oil pipeline 30. A second plug 241 is provided on the pressure measuring port 24. In this embodiment, as... Figure 1 As shown, the pressure measuring port 24 can be equipped with pressure measuring devices such as pressure gauges, which can not only directly obtain the hydraulic oil pressure value in the third oil pipeline 30, but also verify the accuracy of the oil pressure sensor 8.
[0042] As another preferred embodiment of this utility model, the oil inlet of the gear pump 4 is connected to an oil suction filter 42, which is located inside the oil storage tank 1. In this embodiment, as... Figure 2 and Figure 3 As shown, when hydraulic oil enters the oil inlet of gear pump 4, it is filtered by the oil suction filter screen 42, and impurities such as iron particles are intercepted on the oil suction filter screen 42.
[0043] As another preferred embodiment of this utility model, the second end of the integrated base 2 is provided with a first oil inlet 25, which is connected to the oil filling port 21 through a first oil supply pipe 10; on a projection plane perpendicular to the first direction, the projection of the outer wall of the gear pump 4 coincides with the projection portion of the first oil inlet 25. The second end of the integrated base 2 is provided with a second oil inlet 26, which is connected to the second oil port 23 through a second oil supply pipe 20; on a projection plane perpendicular to the first direction, the projection of the outer wall of the gear pump 4 coincides with the projection portion of the second oil inlet 26. In this embodiment, as... Figure 4 and Figure 5 As shown, this structural design allows the hydraulic oil entering the oil storage tank 1 through the first oil inlet 25 and the second oil inlet 26 to flow down along the outer wall of the gear pump 4, avoiding the generation of a large number of air bubbles in the hydraulic oil due to the height difference.
[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
