Description

Technical Field

[0001] This utility model relates to the technical field of combined solenoid valves for air suspension systems, and more particularly to a structure of the moving parts of a solenoid valve. Background Technology

[0002] The combined solenoid valves in automotive air suspension systems are mainly used for flow regulation. To reduce noise and provide magnetic shielding, a magnetic shielding ring is added to the bottom of the moving parts. If the magnetic shielding ring cannot fit snugly against the bottom of the moving parts, it will increase noise and affect flow. Therefore, some manufacturers choose to make a dovetail groove for the magnetic shielding ring at the bottom of the moving parts, so that the magnetic shielding ring is press-fitted into the groove to achieve a complete fit with the bottom of the moving parts. This will reduce the life of the magnetic shielding ring, thereby reducing the life of the solenoid valve and making the product's flow regulation capability more unstable. Utility Model Content

[0003] To address the shortcomings and defects of existing technologies, this invention provides a moving component structure for a solenoid valve. To ensure a stable assembly between the moving component and the magnetic isolation ring, the present invention provides the following technical solution.

[0004] A moving component structure for an electromagnetic valve includes an armature, which has an upper end and a lower end. The cross-sectional diameter of the upper end is smaller than that of the lower end. The upper end has a mounting groove, and a rubber plug is disposed in the mounting groove. The lower end of the lower end is recessed inward toward the upper end to form a dovetail groove, and a magnetic shielding ring is disposed in the dovetail groove. The armature and the magnetic shielding ring are vulcanized together.

[0005] Compared with the prior art, the moving part of the solenoid valve of this utility model has a dovetail groove at the lower end of the armature, which can reduce noise and provide magnetic isolation during use. The magnetic isolation ring is installed in the dovetail groove, which has a good fit and can prevent the magnetic isolation ring from falling off. The improvement is achieved by using the method of integral vulcanization of the armature and the magnetic isolation ring, which reduces the risk of the magnetic isolation ring being scrapped and improves its service life.

[0006] Furthermore, the dovetail groove divides the lower end face of the lower end into an inner circular surface and an outer circular surface, with the height of the inner circular surface being higher than the height of the outer circular surface.

[0007] Through the above improvements, the lower end face of the dovetail groove is divided into an inner circular surface and an outer circular surface. The height of the inner circular surface is higher than that of the outer circular surface, which can prevent the edges of the dovetail groove from wearing and improve the service life of the component.

[0008] Furthermore, the dovetail groove is generally annular, and the dovetail groove includes an inner wall and an outer wall. The outer wall is vertically arranged, the inner wall is inclined, and the diameter of the upper contour line of the inner wall is smaller than the diameter of the lower contour line of the inner wall.

[0009] With the above improvements, the inner wall of the dovetail groove is inclined, and the diameter of the upper contour line of the inner wall is smaller than the diameter of the lower contour line of the inner wall. This allows the inclined inner wall of the dovetail groove to better engage the magnetic shielding ring during installation, preventing the magnetic shielding ring from falling off during use.

[0010] Furthermore, the magnetic shielding ring is generally cylindrical, and the inner diameter of the upper end face of the magnetic shielding ring is smaller than the inner diameter of the lower end face of the magnetic shielding ring.

[0011] Through the above improvements, the inner diameter of the upper end face of the magnetic shielding ring is smaller than that of the lower end face, so that the overall shape of the magnetic shielding ring corresponds to the dovetail groove, which can better match the dovetail groove, reduce the degree of deformation of the magnetic shielding ring, improve its service life, and also make it easier to assemble, further preventing it from falling off.

[0012] Furthermore, the lower end face of the magnetic shielding ring is provided with a groove, and the sides of the groove are semi-circular surfaces.

[0013] With the above improvements, the lower end face of the magnetic shielding ring is provided with a slot, and the sides of the slot are semi-circular surfaces. The slot makes it convenient for operators to assemble and disassemble the ring.

[0014] Furthermore, the magnetic shielding ring is made of rubber material.

[0015] Through the above improvements, the magnetic shielding ring is made of rubber material, which has greater elasticity and strength, and is easy to assemble into the dovetail groove.

[0016] Furthermore, a mating hole is also provided in the lower end portion.

[0017] With the above improvements, a mating hole is also provided in the lower end, which can be used to install other components.

[0018] Furthermore, the upper end face of the lower end and the connection between the lower end face and the side wall are both provided with chamfers.

[0019] Through the above improvements, chamfers are provided at the connection between the upper end face and the side wall of the lower end, as well as at the connection between the lower end face and the side wall. The chamfers can prevent the edges of the lower end from wearing down during movement and reducing service life. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] like Figures 1 to 4 The moving component structure of the solenoid valve shown includes an armature 1, which has an upper end 1.1 and a lower end 1.2. The cross-sectional diameter of the upper end 1.1 is smaller than that of the lower end 1.2. The upper end 1.1 has a mounting groove 1.11 at its upper end, and a rubber plug 4 is provided in the mounting groove 1.11. The lower end 1.2 is recessed inward toward the upper end 1.1 to form a dovetail groove 2, and a magnetic shielding ring 3 is fitted in the dovetail groove 2. The armature 1 and the magnetic shielding ring 3 are vulcanized together.

[0028] The upper end 1.1 and lower end 1.2 of the armature 1 are integrated, and the connection between the upper end 1.1 and the lower end 1.2 is rounded to improve the overall aesthetics of the armature 1. At the same time, the connection between the upper end face and the side wall of the lower end 1.2 and the connection between the lower end face and the side wall are provided with chamfers to prevent the sharp edges of the armature 1 from rubbing against other parts and affecting the overall service life when the armature 1 moves.

[0029] The lower end 1.2 of the armature 1 is divided into an inner circular surface 1.21 and an outer circular surface 1.22 by a dovetail groove 2. The height of the inner circular surface 1.21 is higher than the height of the outer circular surface 1.22, so that the center of the lower end face of the lower end 1.2 of the mounting groove 1.11 is recessed in the direction of the upper end 1.1 to form a mating hole 1.23. The mating hole 1.23 can be used to connect with other components.

[0030] The lower end of the armature 1 is provided with a dovetail groove 2. The dovetail groove 2 is generally annular and includes an inner wall 2.1 and an outer wall 2.2. The outer wall 2.2 is vertically arranged, and the inner wall 2.1 is inclined, so that the cross-sectional shape of the dovetail groove 2 is trapezoidal. The diameter of the upper contour line of the inner wall 2.1 is smaller than the diameter of the lower contour line of the inner wall 2.1. When the dovetail groove 2 is installed with the magnetic shielding ring 3, the inclined inner wall 2.1 of the dovetail groove 2 can better lock the magnetic shielding ring 3 and prevent the magnetic shielding ring 3 from falling off during use.

[0031] The magnetic shielding ring 3, which is configured to cooperate with the dovetail groove 2 at the lower end 1.2, is arranged in a ring-shaped column. The magnetic shielding ring 3 is made of rubber material, which has high elasticity and strength, and is easy to assemble in the dovetail groove 2.

[0032] The outer ring sidewall of the magnetic shielding ring 3 is vertically arranged, while the inner ring sidewall is inclined. The inner ring diameter of the upper end face of the magnetic shielding ring 3 is smaller than that of the lower end face. At the same time, the inclination angle of the inner ring sidewall of the magnetic shielding ring 3 is the same as the inclination angle of the inner wall 2.1 of the dovetail groove 2. This allows for better matching with the dovetail groove 2, facilitating engagement during assembly, reducing the degree of deformation of the magnetic shielding ring 3, improving its service life, and also making assembly easier, further preventing it from falling off.

[0033] A groove 3.1 is recessed at the lower end 1.2 of the magnetic shielding ring 3. The side surfaces on both sides of the groove 3.1 are semi-circular. The groove 3.1 facilitates operation by the operator during assembly and disassembly, reducing the difficulty of operation.

All technical solutions falling within the scope of this utility model's concept are within its protection scope.
