Description

Technical Field

[0001] This utility model relates to the field of electromagnetic pump technology, and more specifically, to an electromagnetic pump quick-connect structure and an electromagnetic pump. Background Technology

[0002] The ABS hydraulic solenoid pump is the core actuator of the anti-lock braking system. Its core function is to rapidly reduce the hydraulic pressure of the corresponding brake caliper when the system detects that a wheel is about to lock up, allowing the wheel to resume rotation; then, it immediately rebuilds the hydraulic pressure to maintain braking force. This "depressurization-pressurization" cycle is performed at a high frequency every second, ensuring that the vehicle has both deceleration efficiency and steering stability during emergency braking. However, the valve block assembly of current hydraulic solenoid pumps has a complex structure and many parts. If an assembly problem occurs during the assembly process, it may cause the entire valve block assembly to malfunction and become unusable.

[0003] The problem is that the existing valve block assembly has many parts and a precise structure. Any assembly error may cause functional failure, resulting in the scrapping of the entire valve block assembly and making it difficult to control the yield rate. Summary of the Invention

[0004] This invention solves the technical problem of existing valve block assemblies having numerous parts and a precise structure, where any assembly error can lead to functional failure, rendering the entire valve block assembly unusable and making it difficult to control the yield rate. This invention integrates the electromagnetic pump parts into a quick-connect structure, forming a pre-assembled module, simplifying the part structure, reducing assembly difficulty, and thus improving the production yield rate.

[0005] To solve the above problems, this utility model provides a quick-connect structure for an electromagnetic pump, comprising: an electromagnetic pump coil with a through hole penetrating the coil; a stop member installed at the bottom of the electromagnetic pump coil and partially placed within the through hole; a magnetic shielding tube installed within the through hole and partially sleeved on the stop member; an armature member disposed within the magnetic shielding tube; and a push rod member penetrating the stop member and having one end in contact with the armature member; wherein, when the stop member is installed on the electromagnetic pump coil, it can confine the magnetic shielding tube, the armature member, and the push rod member within the through hole.

[0006] Compared with existing technologies, the technical benefits of this solution are as follows: By integrating the electromagnetic pump components into a single unit, the original complex valve block assembly structure is significantly simplified, reducing potential assembly complexity and failure rate. Furthermore, due to the integrated design of the components, the assembly process becomes simpler and more efficient, allowing assemblers to more easily install each component, reducing the possibility of assembly errors and thus improving the overall reliability of the product.

[0007] In one possible design, the side of the stop is provided with an oil inlet for introducing high-pressure oil into the electromagnetic pump.

[0008] Compared with existing technologies, the technical advantages of this solution are as follows: integrating the oil inlet into the stop component achieves a high degree of functional integration, significantly reducing the number of parts, simplifying the overall structure, and thus reducing production complexity. Furthermore, directly positioning the oil inlet on the stop component allows for more effective guidance of high-pressure oil into the electromagnetic pump, optimizing the fluid flow path.

[0009] In one possible design, the stop has an internal mounting space that extends through it; the top opening of the mounting space is larger than the bottom opening.

[0010] The top rod is installed within the installation space, and a first elastic component is sleeved on the top rod. The first elastic component is located inside the installation space.

[0011] A second elastic component is provided between the armature and the magnetic shielding tube.

[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: The push rod is installed in the installation space, and its first elastic component provides effective support and cushioning, ensuring smoother movement during electromagnetic engagement and reset, while reducing impact and system wear. Specifically, the first elastic component allows the push rod to quickly return to its position after the electromagnetic coil is de-energized, effectively improving reset speed and stability. The second elastic component facilitates a loose fit between the armature and the magnetic shielding tube, effectively reducing friction and wear, improving the armature's movement flexibility, and ensuring the electromagnetic pump maintains good operating condition during high-frequency operation.

[0013] In one possible design, a sealing ring is fitted at the bottom of the stop.

[0014] The bottom of the stop is provided with a mounting groove for installing a sealing ring.

[0015] Compared with existing technologies, the technical advantages of this solution are as follows: By using an installation groove to fix the sealing ring, it is ensured that the sealing ring is always in the correct position during installation, avoiding leakage caused by the sealing ring's movement or deformation. This significantly improves the sealing effect between the electromagnetic pump and the valve block, preventing media leakage. Furthermore, after the sealing ring is fixed in the installation groove, it can be effectively prevented from shifting or being damaged by external impacts, vibrations, or flushing during operation, thereby extending the service life of the sealing ring and reducing maintenance frequency and replacement costs.

[0016] This application also provides an electromagnetic pump, which includes an electromagnetic pump quick-connect structure and a valve block, wherein the electromagnetic pump quick-connect structure is mounted on the valve block.

[0017] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The electromagnetic pump of this application includes the electromagnetic pump quick-connect structure of any technical solution of this application. Therefore, the electromagnetic pump of this application has all the beneficial effects of the electromagnetic pump quick-connect structure of any technical solution of this application, which will not be elaborated here.

[0018] In one possible design, the valve block is provided with a quick-connect mounting position, and a sealing ring is fitted on the stop. When the electromagnetic pump quick-connect structure is installed on the valve block, the stop is inserted into the quick-connect mounting position, and one end of the sealing ring contacts the outer wall of the stop and the other end contacts the inner wall of the quick-connect mounting position.

[0019] The quick-connect mounting position also has a shaft hole. When the electromagnetic pump quick-connect structure is installed on the valve block, the top rod part is placed in the shaft hole.

[0020] Compared with existing technologies, the technical advantages of this solution are as follows: The quick-connect mounting position allows the electromagnetic pump's quick-connect structure to be quickly and easily connected to the valve block, reducing installation and disassembly time and complexity, and improving overall installation efficiency. Furthermore, the sealing ring ensures a tight fit between the electromagnetic pump and the valve block, effectively preventing media leakage and ensuring airtightness or liquid tightness during operation. This enhances the system's safety and reliability. Attached Figure Description

Detailed Implementation

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] See Figures 1 to 7 This utility model provides a quick-connect structure for an electromagnetic pump, comprising: an electromagnetic pump coil 12 with a through hole penetrating the coil 12; a stop 13 installed at the bottom of the coil 12 and partially placed within the through hole; a magnetic shielding tube 14 installed within the through hole and partially sleeved on the stop 13; an armature 15 disposed within the magnetic shielding tube 14; and a push rod 16 penetrating the stop 13 and having one end in contact with the armature 15. When the stop 13 is installed on the electromagnetic pump coil 12, it can confine the magnetic shielding tube 14, the armature 15, and the push rod 16 within the through hole.

[0025] Specifically, in this embodiment, the electromagnetic pump coil 12 is a hollow annular structure, and the stop 13 is fixedly installed at the bottom of the electromagnetic pump coil 12. The stop 13 is narrower at both ends and wider in the middle. One end of the stop 13 is placed inside the through hole of the electromagnetic pump coil 12, and the middle part of the stop 13 is engaged with the bottom of the electromagnetic pump coil 12. The cooperation between the electromagnetic pump coil 12 and the stop 13 allows the electromagnetic pump quick-connect structure 11 to form an independent pre-assembled module. This allows the electromagnetic pump quick-connect structure 11 to be tested independently after assembly, without needing to be assembled with the valve block 23 to detect assembly problems. This simplifies the component structure, reduces assembly difficulty, and improves the production yield.

[0026] In one embodiment of this application, the side of the stop 13 is provided with an oil inlet hole 17 for introducing high-pressure oil into the electromagnetic pump.

[0027] Specifically, integrating the oil inlet 17 into the side of the stop 13 reduces the number of parts in the electromagnetic pump and optimizes its internal structure. Furthermore, by reducing independent oil inlet components, issues such as seal failure and oil passage blockage caused by multiple connected parts can be reduced. Simultaneously, reducing the number of parts also improves the overall system reliability and lowers the potential risk of oil leakage.

[0028] In one embodiment of this application, a mounting space 18 is provided inside the stop member 13, and the mounting space 18 extends through the stop member 13; wherein, the top opening of the mounting space 18 is larger than the bottom opening. A top rod member 16 is installed in the mounting space 18, and a first elastic member 19 is sleeved on the top rod member 16, and the first elastic member 19 is disposed inside the mounting space 18. A second elastic member 20 is provided between the armature member 15 and the magnetic shielding tube 14.

[0029] Specifically, in this embodiment, both the first elastic component 19 and the second elastic component 20 are springs. To prevent the top rod 16 from sliding out of the stop 13, the top rod 16 is designed with a structure that is thicker at one end and thinner at the other. When the top rod 16 is installed in the mounting space 18 inside the stop 13, the thicker end of the top rod 16 is placed at the top of the mounting space 18 and in contact with the armature 15, while the thinner end is placed at the bottom of the mounting space 18. The first elastic component 19 is sleeved on the thinner end of the top rod 16. When the top rod 16 moves towards the bottom of the mounting space 18, it compresses the first elastic component 19. The second elastic component 20 is disposed between the armature 15 and the magnetic shielding tube 14. When the electromagnetic pump coil 12 is energized, the armature 15 will attract the stop 13, and the armature 15 will push the top rod 16 downward. When the electromagnetic pump coil 12 is de-energized, the top rod 16 will reset under the action of the first elastic component 19. The second elastic component 20 helps to loosen the fit between the armature 15 and the magnetic shielding tube 14, effectively reducing friction and wear, improving the movement flexibility of the armature 15, and ensuring that the electromagnetic pump can maintain a good operating condition when working at high frequency.

[0030] In one embodiment of this application, a sealing ring 21 is fitted onto the bottom of the stop member 13. A mounting groove 22 is provided at the bottom of the stop member 13 for mounting the sealing ring 21.

[0031] Specifically, in this embodiment, the sealing ring 21 is an O-ring; the sealing ring 21 is sleeved on the end of the stop member 13 near the valve block 23, and a mounting groove 22 is formed in the recess of the end of the stop member 13 near the valve block 23. When the sealing ring 21 is installed in the mounting groove 22, the sealing ring 21 partially protrudes from the mounting groove 22 to fit against the inner wall of the quick-connect mounting position 24. By setting the mounting groove to fix the sealing ring, it can be ensured that the sealing ring is always in the correct position during the installation process, avoiding leakage caused by the movement or deformation of the sealing ring.

[0032] like Figure 4 and Figure 5 As shown, this application also provides an electromagnetic pump, which includes an electromagnetic pump quick-connect structure 11 and a valve block 23, with the electromagnetic pump quick-connect structure 11 mounted on the valve block 23.

[0033] Specifically, the electromagnetic pump of this application includes the quick-connect structure of the electromagnetic pump of any technical solution of this application. Therefore, the electromagnetic pump of this application has all the beneficial effects of the quick-connect structure of the electromagnetic pump of any technical solution of this application, which will not be elaborated here.

[0034] In one embodiment of this application, a quick-connect mounting position 24 is provided on the valve block 23, and a sealing ring 21 is fitted on the stop member 13. When the electromagnetic pump quick-connect structure 11 is installed on the valve block 23, the stop member 13 is inserted into the quick-connect mounting position 24, and one end of the sealing ring 21 contacts the outer side wall of the stop member 13, and the other end contacts the inner side wall of the quick-connect mounting position 24. A shaft hole 25 is also provided in the quick-connect mounting position 24. When the electromagnetic pump quick-connect structure 11 is installed on the valve block 23, part of the push rod member 16 is placed in the shaft hole 25.

[0035] Specifically, such as Figure 6 and Figure 7 As shown, in this embodiment, the valve block 23 is provided with a quick-connect mounting position 24 corresponding to the shape of the stop member 13. Simultaneously, a shaft hole 25 is provided at the center of the bottom of the quick-connect mounting position 24. When the electromagnetic pump quick-connect structure 11 is installed on the valve block 23, the push rod 16 part extends outward from the stop member 13 and is placed within the shaft hole 25. The quick-connect mounting position allows the electromagnetic pump quick-connect structure to be quickly and conveniently connected to the valve block, reducing installation and disassembly time and complexity, and improving overall installation efficiency.

[0036] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
