Description

Technical Field

[0001] This utility model relates to the field of solenoid valves, and more specifically, to a solenoid valve cover and a solenoid valve device equipped with the solenoid valve cover. Background Technology

[0002] Automotive shock absorbers are key components of a vehicle's suspension system, used to reduce vibrations during driving and improve ride comfort and stability. With the rapid development of modern automotive technology, more and more vehicles are adopting intelligent shock absorbers to adapt to different road conditions and driving needs. Among these, the solenoid valve, as an important component of the intelligent shock absorber, can quickly adjust the damping force inside the shock absorber via electronic control signals, thereby achieving precise control over the vehicle's dynamic performance.

[0003] While the application of solenoid valves in intelligent shock absorbers improves the dynamic response performance of vehicles, their structure is relatively complex and they are typically exposed to harsh working environments, such as high temperature, high humidity, dust, and vibration. These environmental factors can lead to performance degradation or malfunction of the solenoid valves. To protect the solenoid valves from external environmental influences, a protective cover becomes a key component in its design. Utility Model Content

Detailed Implementation

[0028] To more fully illustrate the technical concept and specific implementation of this utility model, the structure, operation process, and possible technical effects of this utility model will be described below with reference to the accompanying drawings and exemplary embodiments. The embodiments of this utility model involve improvements and innovations in several technical fields. The solutions provided based on these improvements are widely applicable in different scenarios and can be implemented independently or in combination with other technical solutions. This utility model is not limited to the specific embodiments described. In practical applications, those skilled in the art can make various appropriate adjustments without departing from the spirit of this utility model.

[0029] Traditional solenoid valve cover designs typically use rigid plastic or metal materials, but these can present several problems in practical use: complex installation and inconvenient disassembly; durability issues: prolonged exposure to high temperatures, corrosive gases, or vibrations can lead to aging, cracking, or deformation, thus affecting the protection of the solenoid valve. Therefore, there is an urgent need for a solenoid valve cover design that is easy to assemble and maintain to meet the practical needs of automotive shock absorbers under complex operating conditions.

[0030] In some solenoid valve covers, the top surface of the sleeve of the solenoid valve cover has an opening. This opening is fitted onto a protruding structure of the solenoid valve device, and then a fixing device, such as a metal clamp, is installed on the portion of the protruding structure extending beyond the opening on the top surface of the solenoid valve cover to fix the solenoid valve cover to the solenoid valve structure. The inventors of this invention have found that this fixing method is relatively cumbersome in both the manufacturing and installation of the solenoid valve cover. For example, the solenoid valve cover requires an opening process on its top wall and the fabrication of fixing devices such as metal clamps, and the installation process involves numerous steps. Furthermore, because multiple components need to be fitted together, gaps may be introduced between the components, allowing dust and other contaminants to pass through the gaps into the interior of the metal solenoid valve structure during vehicle use, thereby causing malfunctions in the solenoid valve structure.

[0031] At least one embodiment of this utility model provides a solenoid valve cover. The solenoid valve cover includes a main sleeve and a receiving portion for accommodating a lead wire outlet structure of the solenoid valve. The main sleeve includes a cylindrical first sidewall and a first top wall and a first opening located at opposite ends of the first sidewall along the axial direction of the main sleeve. The receiving portion protrudes from the first sidewall of the main sleeve along the radial direction of the main sleeve, and the receiving space within the receiving portion communicates with the receiving space within the main sleeve. The receiving portion includes a second opening, which faces the same direction as the first opening. The receiving portion also includes a second sidewall and a second top wall connected to the second sidewall and axially opposite to the second opening. The second sidewall includes a connecting portion extending along the stated direction, and the connecting portion includes at least two snap-fit ​​structures. According to an embodiment of this utility model, by providing snap-fit ​​structures on the receiving portion for accommodating the lead wire outlet structure of the solenoid valve structure, the solenoid valve cover is securely installed on the solenoid valve structure, avoiding the need for an opening on the top wall of the solenoid valve cover and reducing the difficulty of the solenoid valve cover installation process. Furthermore, since the solenoid valve cover and the components used for connection or fixation are integrated into one structure, there is no need for an opening in the top wall, which avoids gaps between multiple components and thus better prevents dust or other contaminants from entering the interior of the solenoid valve structure.

[0032] Furthermore, according to some embodiments of the present invention, the solenoid valve cover is designed with multiple supporting components located on the inner wall of the solenoid valve cover, such as the supporting ribs, protruding columns and convex ring structures which will be described in detail later, which abut against the solenoid valve structure, thereby cooperating with the snap-fit ​​structure located on the receiving part to more stably install the solenoid valve cover on the solenoid valve structure.

[0033] The embodiments of the present invention will be further described below with reference to the accompanying drawings, so that the technical solution and related technical effects of the present invention will be clearer.

[0034] Figure 1This is a structural schematic diagram of a solenoid valve device equipped with a solenoid valve cover according to this utility model. Figure 1 As shown, the solenoid valve device includes a solenoid valve structure 20 and a solenoid valve cover 10. The solenoid valve structure 20 includes a main body 300 and a wire lead-out structure 400. Figure 1 The portion shown in the diagonal shading is the solenoid valve cover 10, while the portion not shown in the diagonal shading is the solenoid valve structure 20. The solenoid valve structure 20 includes a portion embedded in the solenoid valve cover 10, which cannot be removed from... Figure 1 This is shown in the diagram, and further information can be obtained from subsequent sectional views.

[0035] For example, the main body 300 of the solenoid valve structure 20 has a generally rotationally symmetrical structure. The main body 300 includes, for example, various components such as an electromagnetic coil, armature, pilot valve, and main valve. Since this invention does not particularly limit the main body of the solenoid valve structure but can be applied to various solenoid valve structures, a detailed description of the main body 300 will be omitted here. The wire lead-out structure 400 is used to lead out components such as the wires that supply power to the electromagnetic coil. For example, the wire lead-out structure 400 first protrudes laterally (radially in the direction of the main body) from the side wall of the main body 300 of the solenoid valve structure, and then extends downwards. The aforementioned laterally protruding portion of the wire lead-out structure 400 is accommodated in the solenoid valve cover and cannot be removed from... Figure 1 The diagram shows, but only the downwardly extending portion of the structure is shown. The portion of the lead-out structure 400 housed within the solenoid valve cover can be further understood through subsequent sectional views.

[0036] Figure 2 This is a schematic diagram of the structure of the solenoid valve cover according to an embodiment of the present utility model. Figure 3 This is a perspective view of the solenoid valve cover according to an embodiment of the present utility model. Figure 3 The structure on the inner wall of the solenoid valve cover can be seen. For example... Figure 2 As shown, the solenoid valve cover includes a main sleeve 100 and a receiving portion 200 for accommodating a wire lead-out structure 400 for accommodating the solenoid valve. The main sleeve 100 includes a cylindrical first sidewall 102 and a first top wall 101 and a first opening 103 located at opposite ends of the first sidewall 102 along the axial direction. The receiving portion 200 protrudes radially from the first sidewall 102 of the main sleeve 100, and the receiving space within the receiving portion 200 communicates with the receiving space within the main sleeve 100. The receiving portion 200 includes a second opening 203, which faces the same direction as the first opening 103. The receiving portion 200 includes a second sidewall 202 and a second top wall 201 connected to the second sidewall 202 and disposed opposite to the second opening 203 in the axial direction. The second sidewall 202 includes a connecting portion 2021 extending in the axial direction, and the connecting portion 2021 includes at least two snap-fit ​​structures.

[0037] It should be noted that the axial and radial directions mentioned above are relative to the main sleeve. However, when describing the wire lead-out structure and the receiving portion of the solenoid valve cover, the axial and radial directions are also used. Therefore, when describing the wire lead-out structure and the receiving portion of the solenoid valve cover, directions parallel to the aforementioned axial and radial directions can be used. For example, Figure 1 and Figure 2 The vertical direction is the axial direction, and the horizontal direction is the radial direction.

[0038] For example, the orientation direction of the first opening 103 of the main sleeve 100 and the orientation direction of the second opening 203 of the receiving portion 200 are respectively the directions that each opening faces in the axial direction. For example, the orientation direction of the first opening 102 of the main sleeve 100 and the orientation direction of the second opening 203 of the receiving portion 200 are both... Figure 1 and Figure 2 The direction is downward along the axial direction. These directions are all relative directions; the directions shown in the figure may change when the solenoid valve cover or the solenoid valve device with the solenoid valve cover moves or rotates as a whole. In an embodiment according to this utility model, the receiving part 200 protrudes radially from the first side wall 102 of the main sleeve 100, and the receiving space within the receiving part 200 communicates with the receiving space within the main sleeve 100, thereby simultaneously accommodating the wire lead-out structure of the integrally installed solenoid valve structure and the main body of the solenoid valve structure.

[0039] Figure 2 The connecting part 2021 shown is a snap-fit ​​structure, which can be snapped onto the side wall of the wire lead-out structure of the solenoid valve structure. For example, the side wall of the wire lead-out structure may include a snap-fit ​​structure, or a stepped structure on the edge of the side wall, or the wire lead-out structure may include a groove structure to snap into the snap-fit ​​structure. Further description will be provided in the cross-sectional views described later. However, this invention does not specifically limit the snap-fit ​​structure of the solenoid valve cover; any suitable snap-fit ​​structure can be used, as long as it can snap into the wire lead-out structure.

[0040] like Figure 3 As shown, the first sidewall 102 of the main sleeve 100 includes a notch 1021 for the passage of a wire lead-out structure. The notch 1021 extends from the first opening 103 to near the first top wall 101, and a receiving portion 200 is connected to the end of the notch 1021 near the first top wall 101. This notch is provided to allow the wire lead-out structure to pass through when installing the solenoid valve cover; therefore, the width of the notch can be adapted to the size of the wire lead-out structure and can vary depending on the model and size of different solenoid valve structures.

[0041] like Figure 3As shown, the inner wall of the first sidewall 102 includes a plurality of support ribs 121 extending axially and arranged circumferentially along the main sleeve 100. For example, the support ribs 121 are evenly distributed circumferentially on the inner wall of the first sidewall 102. The support ribs 121 serve two purposes: firstly, they act as reinforcing ribs, thereby increasing the compressive strength of the solenoid valve cover; secondly, the support ribs 121 press against the solenoid valve structure, thereby making the installed solenoid valve cover more stable. The cooperation between the support ribs 121 and the solenoid valve structure will be described in more detail below.

[0042] like Figure 3 As shown, the inner wall of the first sidewall 102 also includes one or more protrusions 111. The protrusions 111 are located axially on the side of the support rib 121 closest to the first top wall 101, and the surface of the protrusion 111 facing the central axis of the main sleeve is closer to the central axis than the surface of the support rib 111 facing the central axis of the main sleeve. For example, the protrusion 111 is closer to the center of the main sleeve than the support rib 121. For example, the surface of the protrusion 111 away from the first top wall 101 and the surface of the second top wall 201 facing the second opening 203 are substantially in the same plane perpendicular to the axial direction. Figure 3 As can be seen, this embodiment includes two protruding posts 111, each corresponding to one of the two supporting ribs 121, while no protruding posts 111 are provided at the other supporting ribs 121. For example, the positions of the protruding posts 111 and the positions of the receiving portions 200 are two opposite positions on the circumference of the first sidewall 102. For example, referring to... Figure 3 If according to Figure 2 In terms of orientation, the protrusion 111 is located on the left side, while the receiving part 200 is located on the right side.

[0043] For example, the number of protruding posts 111 is less than the number of supporting ribs 121, and one or more protruding posts 111 are provided corresponding to the same number of supporting ribs 121. For example, the corresponding arrangement here means that the protruding post and the supporting rib are adjacent to each other.

[0044] The protrusion 111 provides stability to the solenoid valve cover and facilitates disassembly, which will be further described in the subsequent assembly structure.

[0045] like Figure 3As shown, the inner wall of the first sidewall 102 also includes a convex ring structure 131 extending in the circumferential direction. The surface of the convex ring structure 131 facing the central axis of the main sleeve 100 is further away from the central axis than the surface of the support rib 121 facing the central axis of the main sleeve 100, and the convex ring structure 131 is located on the side of the support rib 121 away from the first top wall 101 in the axial direction. For example, in the radial direction, the convex ring structure 131 is positioned further outward than the support rib 121 to press against different parts of the solenoid valve structure.

[0046] like Figure 2 As shown, the first sidewall 102 of the main sleeve 100 includes a direction from the first top wall 101 toward the first opening 103 (e.g., Figure 2 The first part 110, the second part 120, and the third part 130 are connected sequentially from top to bottom. The inner diameter of the first part 110 is smaller than the inner diameter of the third part 130, and the inner diameter of the second part 120 gradually transitions from the inner diameter of the first part 110 to the inner diameter of the third part 130.

[0047] For example, the second top wall 201 is basically flush with the junction of the first part 110 and the second part 120.

[0048] Combination Figure 2 and Figure 3 The protruding post 111 is located on the first portion 110 of the first sidewall 102, and the supporting rib 121 is located on the second portion 120 and the third portion 130 of the first sidewall 102. For example, the supporting rib 121 extends through the entire second portion in the axial direction and extends downward to the third portion. The aforementioned protruding ring structure 131 is provided on the third portion. Figure 3 As shown, the convex ring structure 131 and the support rib 121 are spaced apart from each other in the axial direction.

[0049] For example, such as Figure 2 and Figure 3 As shown, the end of the first sidewall 102 near the first opening 103 includes a plurality of first notches 1301. The notches 1301 make the third part easier to deform in the radial direction, thereby facilitating the assembly of the solenoid valve cover. In addition, the first notches 1301 are located below the convex ring structure 131, so as not to affect the strength and reliability of the entire solenoid valve cover.

[0050] like Figure 2 As shown, a second notch 2022 is included between the connecting portion 2021 of the solenoid valve sleeve and the other parts of the second sidewall 202. For example, the second notch 2022 is provided between the root of the connecting portion 2021 and the other parts of the second sidewall 202. The provision of the second notch 2022 makes the connecting portion easier to deform, facilitating the assembly of the solenoid valve sleeve and the connection with the wire lead-out structure of the solenoid valve structure.

[0051] The structure of the solenoid valve cover has been described above. Since the solenoid valve cover needs to be assembled onto the solenoid valve structure to protect it, the technical effects of each part can be better demonstrated through the assembly relationship. The following describes the solenoid valve device equipped with the solenoid valve cover according to this utility model.

[0052] The solenoid valve device according to an embodiment of the present invention includes: a solenoid valve structure and a solenoid valve cover according to any embodiment of the present invention, wherein the solenoid valve cover is sleeved on the outside of the solenoid valve structure. The external structure of the solenoid valve device can be referred to... Figure 1 The diagram shown is a structural schematic.

[0053] Figure 4 , Figure 5 and Figure 6 These are a structural schematic diagram of the solenoid valve device and cross-sectional structural diagrams taken at different locations. For example, Figure 4 A cross-sectional structural diagram of the wire lead-out structure through the solenoid valve structure and the connection part through the solenoid valve cover. Figure 5 A cross-sectional structural diagram of the middle section of the solenoid valve structure is included. Figure 6 A cross-sectional structural diagram of the portion of the solenoid valve structure opposite to the wire lead-out structure. Figure 4 , Figure 5 and Figure 6 The diagrams show the corresponding section lines AA, BB, and CC, as well as the view direction, on the structural schematic diagrams of the solenoid valve device. Part (B) of these diagrams shows the position of the section lines on the solenoid valve device, and part (A) shows the corresponding cross-sectional structural schematic diagram.

[0054] Combination Figure 1 and Figure 4 As shown, the solenoid valve structure 20 includes a main body 300 and a wire lead-out structure 400 extending from the main body 300. The main sleeve 100 is sleeved on the main body 300, and the receiving part 200 receives the wire lead-out structure 400. The connecting part 2021 is snapped onto the wire lead-out structure 400.

[0055] like Figure 4 As shown, the end snap-fit ​​structure of the connecting portion 2021 snaps into a stepped structure of the wire lead-out structure 400. The snap-fit ​​structure and the snap-fit ​​method with the wire lead-out structure described above are merely exemplary; different snap-fit ​​structures and snap-fit ​​methods can be used according to actual needs. The second top wall 201 and the second side wall 202 of the receiving portion 200 cover the outside of the wire lead-out structure, thereby protecting the wire lead-out structure.

[0056] In an embodiment according to the present invention, as described above, the inner wall of the first sidewall 102 includes support ribs 121 extending in the axial direction and arranged in the circumferential direction of the main sleeve 100. For example... Figure 5 As shown, the main body 300 of the solenoid valve structure 20 includes a coil housing 301, and a support rib 121 presses against the coil housing 301. Since the support ribs 121 are evenly distributed in the circumferential direction, the solenoid valve sleeve can be stably mounted on the solenoid valve structure.

[0057] As described above, the inner wall of the first sidewall 102 also includes a convex ring structure 131 extending in the circumferential direction, wherein the surface of the convex ring structure 131 facing the central axis of the main sleeve is further away from the central axis than the surface of the support rib 121 facing the central axis of the main sleeve, and the convex ring structure 131 is located on the side of the support rib away from the first top wall in the axial direction. Figure 5 As shown, the main body 300 of the solenoid valve structure 20 also includes a threaded sleeve 302, which is fitted over the outside of the coil housing 301, while the convex ring structure 131 presses against the threaded sleeve 302. The radial misalignment of the support rib 121 and the convex ring structure 131 allows them to press against the coil housing and the threaded sleeve respectively, thereby ensuring that each part of the first sidewall is stably supported on the solenoid valve structure.

[0058] like Figure 5 As shown, the portion of the first sidewall 102 of the main sleeve 100 located on the side of the convex ring structure 131 away from the first top wall 101 is spaced apart from the solenoid valve structure. For example, this gap is used to accommodate the solenoid valve connecting sleeve (not shown in the figure). The solenoid valve connecting sleeve is fixed to other components such as a shock absorber. The portion of the solenoid valve structure not covered by the solenoid valve cover extends into the solenoid valve connecting sleeve, and the end of the solenoid valve connecting sleeve extends into the gap between the portion of the first sidewall 102 of the main sleeve 100 located on the side of the convex ring structure 131 away from the first top wall 101 and the solenoid valve structure, and is connected to the threaded sleeve 302 of the solenoid valve structure. Thus, the solenoid valve structure is protected by both the solenoid valve cover and the solenoid valve connecting sleeve.

[0059] As described above, the inner wall of the first side wall 102 of the main sleeve of the solenoid valve cover also includes a protrusion 111. The protrusion 111 is located on the side of the support rib closer to the first top wall 101 in the axial direction, and the surface of the protrusion 111 facing the central axis of the main sleeve 100 is closer to the central axis than the surface of the support rib 121 facing the central axis of the main sleeve 100. For example, the surface of the protrusion 111 away from the first top wall 101 and the surface of the second top wall 201 facing the second opening 203 are substantially in the same plane perpendicular to the axial direction. Figure 6 A schematic cross-sectional view of the structure passing through protrusion 111 is shown. (See diagram.) Figure 6As shown, the protrusion 111 is located between the end of the main body 300 of the solenoid valve structure and the first top wall 101, and the surface of the protrusion 111 away from the first top wall abuts against the main body 300. Figure 5 and Figure 6 As can be seen, the highest point of the main body 300 of the solenoid valve structure is higher than the bottom surface of the protrusion 111, but from... Figure 6 As can be seen, a notch is provided at the location of the protrusion 111 on the main body 300 of the solenoid valve structure, allowing the bottom surface of the protrusion 111 to abut against the main body of the solenoid valve structure. For example, the main body includes a coil housing, and the protrusion 111 abuts against the upper surface of the coil housing. It should be noted that the aforementioned notch on the main body is not necessary and can be omitted depending on the actual situation, as long as the protrusion 111 can abut against the upper side of the main body. The provision of this protrusion not only facilitates the stable fixing of the solenoid valve cover to the solenoid valve structure but also facilitates the disassembly of the solenoid valve cover. For example, when replacing or repairing the solenoid valve device, it is necessary to disassemble the solenoid valve cover. Figure 6 As shown, the connecting part on the receiving part of the solenoid valve cover and the protrusion on the main sleeve of the solenoid valve are respectively located on opposite sides. When disassembling, the snap-fit ​​must first be released. When the snap-fit ​​is released and the receiving part continues to move upward, the protrusion 111 can abut against the main body of the solenoid valve structure, thus serving as a fulcrum, facilitating the disassembly of the solenoid valve cover, and preventing the second side wall from excessively compressing the coil part of the solenoid valve structure during disassembly.

[0060] The above description pertains to a solenoid valve cover and a solenoid valve device equipped with the solenoid valve cover according to embodiments of the present invention. The solenoid valve cover is fixed at the location of the lead wire exit structure, instead of the conventional method of fixing it at the top of the main sleeve, thus simplifying assembly and manufacturing processes. Furthermore, the design of other structures on the inner wall of the cover provides advantages such as installation stability and ease of disassembly.

[0061] It should be noted that the specific embodiments of this utility model are provided only to illustrate the principles and technical features of the invention, and do not constitute a limitation on this utility model. Those skilled in the art can make various modifications and improvements to the specific embodiments within the spirit and scope of this utility model. In particular, for different application scenarios and implementation requirements, the specific structure can be reasonably adjusted to adapt to actual needs without departing from the essential content of this utility model. Therefore, all equivalent substitutions or improvements made within the core idea of ​​this utility model should be considered to fall within the protection scope of this utility model.
