Description

Technical Field

[0001] This invention relates to the technical field of air springs, and more particularly to a solenoid valve connection sealing structure for an electronically controlled vibration damper. Background Technology

[0002] Electronically controlled shock absorbers are a new type of shock absorber that utilizes solenoid valve technology. The core component of an electronically controlled shock absorber is the solenoid valve. Traditional mechanical shock absorbers can typically only be adjusted based on a preset damping coefficient, while electronically controlled shock absorbers can achieve fine-tuning and optimization through the control of the solenoid valve. This results in higher precision and controllability, allowing for precise adjustment of the vehicle's damping effect, effectively improving vehicle stability and handling, and further enhancing ride comfort and safety. The core component of an electronically controlled shock absorber is the solenoid valve, whose basic structure includes an electromagnetic coil, an iron core, and a moving part. The electromagnetic coil consists of a coil wound on the iron core, an insulating ring, and terminals. The coil is the core of the electromagnet and is generally made of copper wire. The iron core is made of ferromagnetic material to enhance the electromagnetic field. The moving part consists of a magnetic disk, a spring, and a sealing gasket. The working principle of the solenoid valve in an electronically controlled shock absorber is mainly achieved by the attraction force generated by the magnetic field of the electromagnet coil on the magnetic disk or the control of the moving part by the magnetic field.

[0003] The current electromagnetic valve of an electronically controlled vibration damper mainly consists of a wiring harness plug, a solenoid valve body, and a solenoid valve mounting housing. The mounting housing seals the wiring harness plug and the solenoid valve body onto the cylinder of the electronically controlled vibration damper. The wiring harness plug mainly includes a solenoid coil body, a housing, and a plug. The solenoid coil body is embedded in the housing, and the plug is located above the protective housing and has a pair of pins. The solenoid valve body mainly includes the valve core (the aforementioned moving part) and the iron core guide post. The solenoid valve body has a first long housing, and the wiring harness plug also has a second long housing. The lower end of the first long housing is threaded, and the upper end has a groove. The lower end of the first long housing is screwed into the mounting housing to insert the solenoid valve body. The upper end of the first long housing is installed with the second long housing through the groove and retaining ring. The mounting housing is inserted between the first and second long housings, and an O-ring is used to achieve a seal between the corresponding first long housing, the mounting housing, and the second long housing. The above-mentioned electromagnetic valve sealing structure of the electronically controlled vibration damper has the following problems: (1) The inner wall of the first long housing and the electromagnetic coil in the wire harness plug form a magnetic flux space. The outer diameter of the coil winding (coil cross-sectional area) of the wire harness plug is limited by the first long housing, that is, the magnetic flux is limited, and thus the damping force value under high current is limited, and the damping force value adjustment range required by some customers cannot be obtained.

[0004] Damping force: The electronically controlled shock absorber is filled with oil and has two chambers, an inner and an outer one. The oil can flow through the gap between the two connected chambers of the electronically controlled shock absorber cylinder. When the wheel bumps, the piston inside the electronically controlled shock absorber moves up and down in the sleeve. The oil in the chamber flows back and forth between the two chambers under the action of the piston's reciprocating motion. The solenoid valve of the electronically controlled shock absorber controls the oil circuit opening and closing to change the resistance of the oil reciprocating between the chambers, thereby changing the damping of the electronically controlled shock absorber. Therefore, the pressure in the main valve chamber of the solenoid valve of the electronically controlled shock absorber can be adjusted by adjusting the current, and thus the damping force of the electronically controlled shock absorber can be adjusted.

[0005] (2) The connection seal between the first long housing and the second long housing uses a combination structure of slot and ring. Although it can limit the axial displacement of the wire harness plug, it cannot limit the radial rotation of the wire harness plug. When the wire harness plug rotates, it will cause the wire harness of the power wire harness plug to interfere with the surrounding parts, causing the wire harness to wear or even break, which in turn causes the overall function of the electronically controlled vibration damper to fail.

[0006] (3) The sealing structure between the wire harness plug and the solenoid valve body and the solenoid valve mounting shell is complicated. Not only does the solenoid valve body need to have a first long shell, but the wire harness plug also needs to have a second long shell. At the same time, the combination of retaining rings and O-rings is required, which is not conducive to the sealing assembly of the solenoid valve and the simplification of the sealing structure.

[0007] Therefore, it is necessary to design a solenoid valve connection sealing structure for an electronically controlled vibration damper to solve the problem that the outer diameter of the electromagnetic coil winding is limited by the first long shell in the above-mentioned solenoid valve connection sealing structure. It also solves the problem of radial rotation of the wire harness plug and the problem of complex assembly of the solenoid valve connection sealing structure. Summary of the Invention

[0008] In view of some of the shortcomings of the prior art, the present invention provides an electromagnetic valve connection sealing structure for an electronically controlled vibration damper. By eliminating the long shell structure outside the electromagnetic valve body and the long shell structure outside the wiring harness plug, the problem of complex electromagnetic valve connection sealing structure and assembly is solved. At the same time, the problem of the cross-sectional area of ​​the electromagnetic coil being limited by the long shell, i.e. the problem of the magnetic flux being limited, is also solved.

[0009] This invention provides a solenoid valve connection sealing structure for an electronically controlled vibration damper, comprising: The wire harness plug includes an electromagnetic coil body, a housing, and a conductive metal ring fitted on the housing. The housing includes a plug section and a sleeve section arranged coaxially. The sleeve section has a receiving space inside, and the inner wall of the sleeve section away from the plug section has a receiving groove for accommodating the electromagnetic coil body. The receiving groove and the receiving space are arranged coaxially. The solenoid valve body includes a valve core and a guide post coaxially arranged, the guide post extending integrally outward from the valve core and coaxially inserted into the receiving space of the sleeve section of the housing; and The valve body mounting shell is coaxially sleeved outside the sleeve section of the solenoid valve body and the wiring harness plug. The first end of the valve body mounting shell is connected to the cylinder side wall of the shock absorber cylinder. The second end of the valve body mounting shell, which is opposite to the first end, extends to the outside of the sleeve section of the shell and is sealed with the sleeve section by a first O-ring.

[0010] In one embodiment of the present invention, a first U-shaped groove is provided on the outer periphery of the conductive metal ring of the wire harness plug, and the valve body mounting shell is provided with at least three riveting protrusions that are recessed into the first U-shaped groove. Each riveting protrusion protrudes into the first U-shaped groove and forms a riveting structure with the groove wall corresponding to the first U-shaped groove.

[0011] In one embodiment of the present invention, three riveting protrusions are evenly provided on the circumference of the valve body mounting shell corresponding to the first U-shaped groove.

[0012] In one embodiment of the present invention, the conductive metal ring is embedded in a groove on the outer cylindrical surface of the sleeve section and close to the electromagnetic coil body.

[0013] In one embodiment of the present invention, a second U-shaped groove is provided on one end of the outer cylindrical surface of the second end of the sleeve section corresponding to the valve body mounting shell, and a first O-ring is disposed in the second U-shaped groove to achieve a seal between the sleeve section of the wire harness plug and the valve body mounting shell.

[0014] In one embodiment of the present invention, a positioning boss is formed on the outer cylindrical surface above the second U-shaped groove of the sleeve section, and the second end of the valve body mounting shell abuts against the lower end face of the positioning boss.

[0015] In one embodiment of the present invention, the plug section of the housing is provided with a socket, and a pair of pins are provided in the socket. When the power harness plug is inserted into the socket, the electromagnetic coil body is connected to the positive and negative terminals of the power supply through the pair of pins.

[0016] In one embodiment of the present invention, the diameter of the valve core of the solenoid valve body is larger than the diameter of the guide post, so that a countersunk platform is formed at one end of the valve core corresponding to the guide post. When the guide post is inserted into the receiving space of the sleeve section of the housing, the corresponding end face of the sleeve section contacts the countersunk platform of the valve core.

[0017] In one embodiment of the present invention, the outer surface of the valve core of the solenoid valve body near the guide post is provided with a threaded connection portion that is threadedly connected to the valve body mounting shell.

[0018] In one embodiment of the present invention, a third U-shaped groove is provided on the outer surface of the threaded connection portion of the valve core of the solenoid valve body near the guide post, and a second O-ring is disposed in the third U-shaped groove to achieve a seal between the solenoid valve body and the valve body mounting shell.

[0019] In one embodiment of the present invention, an end cap is provided at the end of the sleeve section of the housing that is away from the plug end, and the end cap and the sleeve section are fixedly connected so that the electromagnetic coil body is housed in the receiving groove of the sleeve section.

[0020] The beneficial technical effects of the present invention include at least the following: The present invention discloses a solenoid valve connection sealing structure for an electronically controlled vibration damper, comprising a wiring harness plug, a solenoid valve body, and a valve body mounting shell. The wiring harness plug includes an electromagnetic coil body, a housing, and a conductive metal ring fitted on the housing. The solenoid valve body includes a valve core and a guide post coaxially arranged. The valve body mounting shell is coaxially fitted outside the sleeve section of the solenoid valve body and the wiring harness plug. The first end of the valve body mounting shell is connected to the cylinder side wall of the vibration damper cylinder. The second end of the valve body mounting shell extends and is sealed to the sleeve section by a first O-ring. The valve body mounting shell is provided with at least three riveting protrusions recessed into a first U-shaped groove. Each riveting protrusion protrudes into the first U-shaped groove and forms a riveting structure with the groove wall corresponding to the first U-shaped groove.

[0021] Therefore, neither the wiring harness plug nor the solenoid valve body in the solenoid valve connection sealing structure of the present invention has a long shell. Instead, the long shell outside the wiring harness plug and the solenoid valve body in the prior art is replaced by extending the valve body mounting shell. The second end of the valve body mounting shell and the sleeve section are sealed by the first O-ring to achieve the sealing of the valve body mounting shell and the sleeve section. At the same time, the guide post of the solenoid valve body is inserted into the receiving space of the sleeve section of the wiring harness plug. The first U-shaped groove on the outer periphery of the conductive metal ring outside the sleeve section and the riveting protrusion of the valve body mounting shell form a riveting structure to achieve the connection between the valve body mounting shell and the sleeve section. In summary, the solenoid valve body of this invention has no long shell, which solves the problem that the outer diameter (cross-sectional area of ​​the solenoid coil) of the wiring harness plug is limited by the long shell, i.e., the magnetic flux is limited. This allows for the achievement of a corresponding damping force value even under high current, thus obtaining the damping force adjustment range required by the customer. The sleeve section of the wiring harness plug is connected by a riveting structure formed by the first U-shaped groove of the conductive metal ring and the riveting protrusion of the valve body mounting shell, solving the problem of radial rotation of the wiring harness plug, ensuring the safety of the solenoid valve and extending its service life. At the same time, the long shell of the wiring harness plug is also eliminated. Combined with the absence of a long shell on the solenoid valve body, the overall connection and sealing structure of the solenoid valve is optimized, which simplifies the production mold, assembly steps and components, reduces production costs and saves resources.

[0024] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0027] Please see Figure 1 The present invention discloses a solenoid valve connection sealing structure for an electronically controlled vibration damper, comprising a wiring harness plug 1, a solenoid valve body 2, and a valve body mounting shell 3. The wiring harness plug 1 includes a solenoid coil body 11, a housing 12, and a conductive metal ring 123 fitted onto the housing 12. The housing 12 includes a plug section 121 and a sleeve section 122 coaxially arranged. The sleeve section 122 has a receiving space 1221, and the inner wall of the sleeve section 122, away from the plug section 121, has a receiving groove 1222 for accommodating the solenoid coil body 11. The receiving groove 1222 and the receiving space 1221 are coaxially arranged. The solenoid valve body 2 includes a valve core 21 coaxially arranged and a guide... The guide post 22 extends integrally outward from the valve core 21 and is coaxially inserted into the receiving space 1221 of the sleeve section 122 of the housing 12; and the valve body mounting shell 3 is coaxially sleeved outside the sleeve section 122 of the solenoid valve body 2 and the wiring harness plug 1. The first end 31 of the valve body mounting shell 3 is connected to the cylinder side wall of the shock absorber cylinder, and the second end 32 of the valve body mounting shell 3, which is opposite to the first end 31, extends to the outside of the sleeve section 122 of the housing 12 and is sealed with the sleeve section 122 by the first O-ring 51.

[0028] Therefore, when the electromagnetic coil body 11 of the present invention is energized, a sealed magnetic flux is formed between the valve body mounting shell 3, the electromagnetic coil body 11, and the conductive metal ring 123. This eliminates the need for a long outer shell on the electromagnetic valve body, increasing the outer diameter (coil cross-sectional area) of the coil winding of the electromagnetic coil body 11. This allows it to extend closer to the valve body mounting shell, enabling the electromagnetic valve body 2 to obtain a corresponding damping force value under high current. This increases the adjustment range of the electromagnetic valve's damping force value, meeting customer needs. Simultaneously, the combination with the wiring harness plug 1 also eliminates the limitation of the external long shell, optimizing the overall connection and sealing structure of the electromagnetic valve of the present invention. This simplifies the production mold, assembly steps, and assembly components, reducing production costs and saving resources.

[0029] In one embodiment of the present invention, the conductive metal ring 123 is embedded in the groove 124 on the outer cylindrical surface of the sleeve section 122 and close to the electromagnetic coil body 11. The plug section 121 of the housing 12 is provided with a socket 127, and a pair of pins 1271 are provided in the socket 127. When the power cord plug is inserted into the socket 127, the electromagnetic coil body 11 is connected to the positive and negative terminals of the power supply through the pair of pins 1271. The electromagnetic coil body 11 is energized, and a sealed magnetic flux is formed between the valve body mounting shell 3, the electromagnetic coil body 11 and the conductive metal ring 123.

[0030] In one embodiment of the present invention, a first U-shaped groove 1231 is formed on the outer periphery of the conductive metal ring 123 of the wire harness plug 1. Three riveting protrusions 33 are evenly provided on the circumference of the valve body mounting shell 3 corresponding to the first U-shaped groove 1231. Each riveting protrusion 33 protrudes into the first U-shaped groove 1231 and forms a riveting structure with the groove wall corresponding to the first U-shaped groove 1231. The valve body mounting shell 3 and the sleeve section 122 of the wire harness plug 1 are connected by the riveting structure. The outer surface of the end of the valve core 21 of the solenoid valve body 2 near the guide post 22 is provided with a threaded connection part 213 that is threadedly connected to the valve body mounting shell 3. Therefore, the threaded connection between the valve body mounting shell 3 and the valve core 21 can be realized, that is, the connection between the valve body mounting shell 3 and the solenoid valve body 2.

[0031] In one embodiment of the present invention, a second U-shaped groove 125 is provided at one end of the outer cylindrical surface of the second end 32 of the sleeve section 122 corresponding to the valve body mounting shell 3. A first O-ring 51 is disposed in the second U-shaped groove 125 to achieve a seal between the sleeve section 122 of the wire harness plug 11 and the valve body mounting shell 3. A third U-shaped groove 212 is provided on the outer surface of the threaded connection portion 213 of the valve core 21 of the solenoid valve body 2 near the guide post 22. A second O-ring 52 is disposed in the third U-shaped groove 212 to achieve a seal between the solenoid valve body 2 and the valve body mounting shell 3.

[0032] In one embodiment of the present invention, a positioning boss 126 is formed on the outer cylindrical surface above the second U-shaped groove 125 of the sleeve section 122, and the second end of the valve body mounting shell 3 abuts against the lower end face of the positioning boss 126. The diameter of the valve core 21 of the solenoid valve body 2 is larger than the diameter of the guide post 22, so that a countersunk 211 is formed at one end of the valve core 21 corresponding to the guide post 22. When the guide post 22 is inserted into the receiving space 1221 of the sleeve section 122 of the shell 12, the corresponding end face of the sleeve section 122 contacts the countersunk 211 of the valve core 21.

[0033] In one embodiment of the present invention, an end cap 1223 is provided at the end of the sleeve section 122 of the housing 12 away from the plug end 121, and the end cap 1223 and the sleeve section 122 are fixedly connected, so that the electromagnetic coil body 11 is received in the receiving groove 1222 of the sleeve section 122. The fixed connection between the end cap 1223 and the sleeve section 122 can be one of welding, riveting or threaded connection, and is not limited to the above-mentioned fixed connection methods.

[0034] In summary, the electromagnetic valve connection sealing structure of the electronically controlled vibration damper of the present invention connects the valve body mounting shell 3 and the sleeve section 122 of the wiring harness plug 1 through a riveting structure, and the valve body mounting shell 3 and the valve core 21 are connected by threads, i.e., the valve body mounting shell 3 and the electromagnetic valve body 2 are connected. The first O-ring 51 is disposed in the second U-shaped groove 125 to achieve a seal between the sleeve section 122 of the wiring harness plug 11 and the valve body mounting shell 3, and the second O-ring 52 is disposed in the third U-shaped groove 212 to achieve a seal between the electromagnetic valve body 2 and the valve body mounting shell 3. The above structure realizes the positioning connection and sealing between the valve body mounting shell 3, the wiring harness plug 1 and the electromagnetic valve body 2.

[0035] Meanwhile, the outer cylindrical surface above the second U-shaped groove 125 of the sleeve section 122 protrudes to form a positioning boss 126. The second end 32 of the valve body mounting shell 3 abuts against the lower end face of the positioning boss 126, limiting the second end 32 of the valve body mounting shell 3. The diameter of the valve core 21 of the solenoid valve body 2 is larger than the diameter of the guide post 22, so that the end of the valve core 21 corresponding to the guide post 22 forms a countersunk platform 211. When the guide post 22 is inserted into the receiving space 1221 of the sleeve section 122 of the shell 12, the corresponding end face of the sleeve section 122 contacts the countersunk platform 211 of the valve core 21, limiting the sleeve section 122. The relative positional relationship between the valve body mounting shell 3, the wire harness plug 1 and the solenoid valve body 2 is realized.

[0036] Therefore, the present invention can solve the following problems: (1) The problem of the outer diameter (cross-sectional area of ​​electromagnetic coil) of the electromagnetic coil body 11 of the wire harness plug 1 being limited by the long shell is solved. The electromagnetic valve body 2 of the present invention has no long shell, and the magnetic flux is not limited by the long shell outside the electromagnetic valve body 2, so that the electronically controlled damper can obtain the corresponding damping force value under high current, and thus obtain the damping force value adjustment range required by the customer.

[0037] The electronically controlled shock absorber is filled with oil and has two chambers, an inner and an outer one. The oil can flow through the orifice between the two connected chambers of the shock absorber's cylinder. When the wheel bumps, the piston inside the shock absorber moves up and down in the sleeve, and the oil in the chamber flows back and forth between the two chambers under the action of the piston's reciprocating motion. The solenoid valve of the electronically controlled shock absorber controls the opening and closing of the oil circuit to change the resistance of the oil reciprocating between the chambers, thereby changing the damping of the electronically controlled shock absorber. Therefore, the pressure in the main valve chamber of the solenoid valve of the electronically controlled shock absorber can be adjusted by adjusting the current, and thus the damping force of the electronically controlled shock absorber can be adjusted.

[0038] (2) The problem of radial rotation of the wire harness plug 1 is solved. The sleeve section 122 of the wire harness plug 1 is connected by forming a riveting structure through the first U-shaped groove 1231 of the conductive metal ring 123 and the riveting protrusion 33 of the valve body mounting shell 3. This avoids interference between the wire harness of the power wire harness plug and the surrounding components, which would cause wear or even breakage of the wire harness, and thus cause the overall function of the electric vibration damper to fail. This ensures the safe use of the solenoid valve of the electric vibration damper and extends its service life. (3) The problem of complex assembly of the solenoid valve connection sealing structure is solved. The long shell of the wire harness plug 1 is eliminated. Combined with the fact that the solenoid valve body 2 has no long shell, the overall solenoid valve connection sealing structure of the electric vibration damper of the present invention is optimized. Accordingly, the production mold is simplified, as well as the assembly steps and assembly components are simplified, reducing production costs and saving resources.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
