Description

Technical Field

[0001] This utility model relates to the field of thermal management technology, specifically to a valve device and a coil device. Background Technology

[0002] The valve assembly mainly consists of a valve seat, a valve body, and a coil component. The valve seat is located between the valve body and the coil component, and the coil component is sleeved outside the valve seat and is connected to the valve body for limiting. Under vibration conditions, the coil component of the valve assembly is prone to swaying relative to the valve body, affecting the reliability of the valve assembly. Summary of the Invention

[0003] The purpose of this utility model is to provide a valve device and a coil device, which aims to solve the problem of loose connection between the coil component and the valve body.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model provides a valve device, comprising: a first component and a second component, one of which is a coil component and the other is a valve body; a connector fixedly connected to the first component; the second component including a first stop and a second stop, with an installation gap between the first stop and the second stop; the first stop including an abutment portion, and at least one of the first stop and the second stop further including a first snap-fit ​​portion; the connector including a first connecting portion, the first connecting portion including a second snap-fit ​​portion and a limiting portion; the limiting portion extending along the arrangement direction of the first component and the second component; the second snap-fit ​​portion located at the end of the limiting portion away from the first component; at least a portion of the limiting portion located in the installation gap; along the thickness direction of the limiting portion, one side of the limiting portion abuts against the abutment portion, and the other side of the limiting portion abuts against the second stop; the second snap-fit ​​portion snaps against the first snap-fit ​​portion.

[0006] According to the valve device provided by this utility model, since the limiting part is at least partially located in the installation gap, the limiting part is located between the first stop and the second stop. When the limiting part is in the assembled state, one side of the limiting part is pressed and abutted by the first stop, and the other side of the limiting part is pressed and abutted by the second stop. Through the above arrangement, the friction between the limiting part and the first stop and the second stop is increased, which is conducive to the tighter engagement between the connecting piece and the second component, thereby making the first component and the second component less likely to loosen.

[0007] On the other hand, the present invention also provides a coil device, including a coil component and a connector. The connector is fixedly connected to the coil component. The connector includes a first connecting portion, the first connecting portion including a second snap-fit ​​portion and a limiting portion. The limiting portion extends along the axial direction of the coil component. The second snap-fit ​​portion is located at the end of the limiting portion away from the coil component. The limiting portion has an elastic structure, and the angle between the limiting portion and the axial direction of the coil component can be adjusted.

[0008] According to the coil device provided by this utility model, the angle between the limiting part and the coil component in the axial direction can be adjusted, so that the limiting part has an elastic restoring force when squeezed, which can increase the squeezing force between the connector and the components other than the coil device, and improve the tightness of the connection between the two.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0023] Currently, under vibration conditions, the electronic expansion valve may experience coil swaying relative to the valve body, resulting in an insufficiently tight connection between the coil and the valve body, thus affecting the reliability of the electronic expansion valve.

[0024] To address the aforementioned problems, this application provides a valve device comprising: a first component A and a second component B, wherein one of the first component A and the second component B is a coil component 1, and the other is a valve body 3; a connector 2, which is fixedly connected to the first component A; the second component B includes a first stop portion 31 and a second stop portion 32, with an installation gap H between the first stop portion 31 and the second stop portion 32; the first stop portion 31 includes an abutment portion 311, and at least one of the first stop portion 31 and the second stop portion 32 further includes a first snap-fit ​​portion 312; and the connector... 2 includes a first connecting portion 21, which includes a second engaging portion 212 and a limiting portion 211. The limiting portion 211 extends along the arrangement direction of the first component A and the second component B. The second engaging portion 212 is located at the end of the limiting portion 211 away from the first component A. At least a portion of the limiting portion 211 is located in the installation gap H. Along the thickness direction of the limiting portion 211, one side of the limiting portion 211 abuts against the abutting portion 311, and the other side of the limiting portion 211 abuts against the second stop portion 32. The second engaging portion 212 engages with the first engaging portion 312.

[0025] like Figure 2 As shown, the connector 2 is located outside the first component A or the second component B and is fixedly connected to one of the first component A and the second component B, such as by welding, riveting, or integral molding. Simultaneously, the connector 2 is snapped into the other of the first component A and the second component B. Optionally, in the valve device of this embodiment, the first component A is a coil component 1, and the second component B is a valve body 3. The coil component 1, the connector 2, and the valve body 3 are sequentially distributed along the axial direction of the coil component 1. The connector 2 can be located at one end of the coil component 1 near the valve body 3, and the connector 2 is welded and fixed to the coil component 1. The first stop portion 31 and the second stop portion 32 are located on the same side wall of the valve body 3. The first connecting portion 21 of the connector 2 can be snapped into the valve body 3 by engaging with either the first stop portion 31 or the second stop portion 32. An installation gap H extending along the axial direction of the coil component 1 is provided between the first stop portion 31 and the second stop portion 32 for installing the limiting portion 211 of the first connecting portion 21. When the connector 2 and valve body 3 are in the engaged state, the limiting part 211 is at least partially located in the installation gap H. The limiting part 211 presses against the wall that defines the installation gap H, which allows the limiting part 211 to engage more tightly with the valve body 3. Optionally, such as Figure 1 and Figure 4 As shown, one part of the limiting part 211 is located inside the installation gap H, and the other part of the limiting part 211 is located outside the installation gap H. At this time, the limiting part 211 abuts against the first stop part 31 and the second stop part 32 on both sides in the thickness direction. This arrangement increases the friction between the limiting part 211 and the valve body 3, which is beneficial to the tightness of the engagement between the limiting part 211 and the valve body 3.

[0026] In one embodiment, the connector 2 further includes a second connecting portion 22 and a first transition portion 23. The second connecting portion 22 is fixedly connected to the first component A. The first transition portion 23 connects the first connecting portion 21 and the second connecting portion 22. The first transition portion 23 is bent relative to the second connecting portion 22 and is elastic. The limiting portion 211 has a second transition portion 215 and a third transition portion 216. The second transition portion 215 is at least partially located outside the mounting gap H, and the third transition portion 216 is at least partially located inside the mounting gap H. One end of the second transition portion 215 is connected to the first transition portion 23.

[0027] Because the first transition portion 23 has an elastic structure, such as an arc-shaped elastic element, the limiting portion 211 causes the first transition portion 23 to undergo compression deformation, thereby increasing the compression force between the limiting portion 211 and the first stop portion 31. Furthermore, the first transition portion 23 can buffer the force generated when the first connecting portion 21 abuts against the first stop portion 31, protecting the connection between the first connecting portion 21 and the second connecting portion 22. Simultaneously, the third transition portion 216, located within the installation gap H, presses against the second stop portion 32. Due to the elasticity of the limiting portion 211, the third transition portion 216 causes the second locking portion 212 to shift towards the first stop portion 31, facilitating the locking of the second locking portion 212 against the first locking portion 312. Positioning the second transition portion 215 outside the installation gap H allows for greater deformation space for the limiting portion 211. Because of the pressing and limiting effect of the abutting part 311 of the first stop part 31 and the pressing part 32 of the second stop part 32, the connecting member 2 cannot rotate or move. Therefore, it can restrict the movement and rotation of the coil component 1 that is fixedly connected to the connecting member 2 to a certain extent, reducing the possibility of the connecting member 2 disengaging from the valve seat 4, thereby realizing a reliable connection between the coil component 1 and the valve seat 4.

[0028] In one embodiment, the projection of the second transition portion 215 along the axial direction of the first component A is located on the first stop portion 31, and the limiting portion 211 has an elastic structure. At this time, the limiting portion 211, located at the boundary between the mounting gap H and the mounting gap H, can be pressed against the first stop portion 31, causing the first transition portion 23 to deform, resulting in the limiting portion 211 tilting. Furthermore, the second transition portion 215 has a deformation towards the mounting gap H, which on the one hand allows the limiting portion 211 to have sufficient deformation space during deformation, and on the other hand helps prevent the limiting portion 211 from breaking under pressure. It should be noted that the first transition portion 23 can have an elastic restoring force when pressed by the first stop portion 31; therefore, the second transition portion 215 along the axial direction of the first component A is not limited to the case where it can only be projected onto the end of the first stop portion 31 near the coil component 1. To facilitate the restoring force of the first connecting portion 21 when it abuts the first stop portion 31, in the state where the first connecting portion 21 is not abutting the first stop portion 31, such as... Figure 7 As shown, the first transition portion 23 allows the angle α between the first connecting portion 21 and the second connecting portion 22 to be an acute angle, a right angle, or an obtuse angle. For example, if the position and size of the installation gap H remain unchanged, and the angle between the first connecting portion 21 and the second connecting portion 22 is an obtuse angle, the first transition portion 23 can have a greater elastic restoring force after being squeezed by the abutment portion 311, which is beneficial to increasing the friction between the first connecting portion 21 and the first stop portion 31. Furthermore, the elastic structure of the limiting portion 211 is beneficial to the reliability of the limiting portion 211 under compressive force.

[0029] In one embodiment, the second transition portion 215 has a first wall surface 214 connected to the first transition portion 23. The first wall surface 214 abuts against the abutting portion 311. Along the axial direction of the first component A, at least a portion of the projection of the first wall surface 214 is located on the first stop portion 31. The second snap-fit ​​portion 212 is bent toward the first stop portion 31 and snaps into the first stop portion 31.

[0030] The first wall surface 214 is one end face of the second transition portion 215 near the first stop portion 31. Optionally, when the first connecting portion 21 abuts against the first stop portion 31, the first wall surface 214 is inclined relative to the wall surface defining the installation gap H of the first stop portion 31. The first wall surface 214 serves as the pressing surface between the abutting portion 311 and the first stop portion 31, causing the first transition portion 23 to bend and exhibit a tendency to return to its original position, i.e., it possesses a restoring force. Simultaneously, the wall surface opposite to the first wall surface 214, the limiting portion 211, abuts against the second stop portion 32. Under the pressing force of the second stop portion 32, the connecting member 2 and the first stop portion 31 are more tightly engaged.

[0031] In one embodiment, the installation gap H includes a first limiting groove 33, the second component B has a second wall surface 35, the second wall surface 35 is an end face close to the first component A, the first limiting groove 33 extends from the second wall surface 35 along the axial direction of the first component A, and the first stop portion 31 and the second stop portion 32 face each other and define the wall portion of the first limiting groove 33 by the wall portion and a portion of the wall portion of the second component B.

[0032] like Figure 2 and Figure 4 As shown, the first limiting groove 33, the first stop portion 31, and the second stop portion 32 are located on the same side of the valve body 3. The first limiting groove 33 is located between the first stop portion 31 and the second stop portion 32. The valve body 3 has a second wall surface 35, which is located on the side of the valve body 3 closer to the coil component 1. The first limiting groove 33 starts from the second wall surface 35 and extends away from the coil component 1, along the arrangement direction of the first stop portion 31 and the second stop portion 32. The dimensions between the sidewall portions of the first limiting groove 33 are sufficient to allow the limiting portion 211 to be installed into the first limiting groove 33. This arrangement facilitates the assembly of the limiting portion 211. When the connecting piece 2 engages with the first stop portion 31, a portion of the limiting portion 211 is located within the first limiting groove 33 and presses against the first limiting groove 33, thus achieving mutual limiting of the coil component 1 and the valve body 3.

[0033] In one embodiment, the second component B has a receiving portion 34 located at one end of the first limiting groove 33 and communicating with the first limiting groove 33. The extending direction of at least a portion of the receiving portion 34 intersects the extending direction of the first limiting groove 33, and at least a portion of the second snap-fit ​​portion 212 is located inside the receiving portion 34.

[0034] like Figure 2 and Figure 4 As shown, the receiving portion 34 and the first limiting groove 33 are located on the same side of the valve body 3. Optionally, the receiving portion 34 is located at the end of the first limiting groove 33 away from the coil component 1, and the receiving portion 34 extends in a direction perpendicular to the first limiting groove 33. The second engaging portion 212 is located at the end of the first connecting portion 21 away from the coil component 1, such that the second engaging portion 212 is located inside the receiving portion 34, and the second engaging portion 212 can engage with the end face of the first stop portion 31 away from the coil component 1. The receiving portion 34 can better limit the first connecting portion 21, and since the receiving portion 34 and the first limiting groove 33 are located on the same side of the valve seat 4, the structure is simple and easy to process.

[0035] In some other embodiments, to further improve the tightness of the connection between the connector 2 and the valve body 3, at least two first connecting portions 21, first transition portions 23, first limiting grooves 33, and receiving portions 34 are arranged in a circumferential array relative to the coil component 1. Optionally, two first connecting portions 21 and first transition portions 23 are disposed on opposite sides of the valve body 3. To enable them to engage with the valve body 3, the valve body 3 has two first limiting grooves 33 and two receiving portions 34. The first limiting grooves 33 and receiving portions 34 are arranged according to the position of the first connecting portion 21 relative to the valve body 3, and each first connecting portion 21 cooperates with one first limiting groove 33 and one receiving portion 34.

[0036] In one embodiment, the third transition portion 216 includes a protrusion 213, one end of which is connected to the second transition portion 215, and the other end of which is connected to the second snap-fit ​​portion 212. The protrusion 213 is located in the first limiting groove 33 and protrudes toward the wall of the first limiting groove 33 that is pressed against the protrusion 213. The protrusion 213 has an elastic structure.

[0037] To further increase the tightness of the engagement between the first connecting part 21 and the first stop part 31 and the second stop part 32, such as Figure 2 and Figure 4 As shown, a protrusion 213 is provided on the limiting part 211. The protrusion 213 is an elastic structure and therefore has the property of elastic deformation. In some embodiments, the protrusion 213 is an arc-shaped protrusion. The protrusion 213 can be squeezed by the wall of the first limiting groove 33. Due to the elastic deformation property of the protrusion 213, the protrusion 213 undergoes elastic deformation under the pressure of the wall of the second stop part 32. Therefore, the protrusion 213 has a tendency to recover, which increases the friction with the second stop part 32 and thus increases the tightness of the connection between the first connecting part 21 and the valve body 3.

[0038] Furthermore, since the protrusion direction of the protrusion 213 is opposite to that of the first stop 31, and the part of the connector 2 near the coil component 1 is fixedly installed, the protrusion 213 will drive the connector 2 to reset towards the first stop 31 under compression, thereby making the second snap-fit ​​part 212 located in the receiving part 34 snap-fit ​​more tightly with the first stop 31.

[0039] like Figure 2 and Figure 3As shown, the second transition portion 215 is located at the end of the first connecting portion 21 near the coil component 1. To further improve the convenience of installing the first connecting portion 21 into the first limiting groove 33 and the tightness of the engagement, the first connecting portion 21 is provided with a third transition portion 216. The third transition portion 216 includes a protrusion 213 and a straight section 218. In one embodiment, one end of the protrusion 213 is connected to the second engaging portion 212, and the other end of the protrusion 213 is connected to the second transition portion 215. By providing the second transition portion 215 and the third transition portion 216, the overall length of the connecting member 2 can be extended, which can adapt to the length and angle of the limiting groove on the valve body 3. Providing the third transition portion 216 can extend the length of the first connecting portion 21. For example, the axial length of the first connecting portion 21 is slightly less than the axial length of the first limiting groove 33, which allows the first connecting portion 21 to engage more tightly with the first stop portion 31. Furthermore, as... Figure 3 As shown, the straight section 218 has a third wall surface 217. The centers of the first wall surface 214, the third wall surface 217, and the protrusion 213 are located on the same side of the limiting section 211. A plane P is defined, which includes the central axis of the coil component 1 and is parallel to the first wall surface 214 and the third wall surface 217. The shortest distance between the first wall surface 214 and the plane P is the first spacing L1, and the shortest distance between the third wall surface 217 and the plane P is the second spacing L2. When the connector 2 and the valve body 3 are not in a snap-fit ​​state, the second transition section 215 and the straight section 218 are parallel to the wall of the first limiting groove 33 and along the direction of the protrusion of the protrusion 213, there is a certain distance between the second transition section 215 and the straight section 218. This distance is the difference between the first spacing L1 and the second spacing L2, wherein the first spacing L1 is greater than the second spacing L2. This arrangement ensures that the second locking portion 212 is at least partially located within the axial extension direction of the first limiting groove 33, facilitating the insertion of the limiting portion 211 into the first limiting groove 33. Furthermore, the distance between the second transition portion 215 and the straight section 218 allows for sufficient elastic deformation space for the protrusion 213.

[0040] Optionally, the second latching part 212 is a hook, with the hook bending towards the first stop part 31. Specifically, the end of the hook away from the coil component 1 has an inclined surface, which is inclined relative to the axial direction of the coil component 1. Due to the elasticity of the limiting part 211 and the presence of the inclined surface of the hook, the inclined surface can provide guidance during the insertion of the first connecting part 21 into the valve body 3, which is beneficial to the installation of the first connecting part 21 and the first stop part 31.

[0041] With the first connecting portion 21 installed in the first limiting groove 33, the protrusion 213 is deformed by compression within the first limiting groove 33 along the arrangement direction of the first stop portion 31 and the second stop portion 32. This reduces the distance between the protrusion 213 and the first stop portion 31, thereby causing the second engaging portion 212 to move towards the first stop portion 31, resulting in a tighter engagement between the second engaging portion 212 and the first stop portion 31. Furthermore, the protrusion 213 is deformed by compression along the extending direction of the first limiting groove 33, increasing the distance between the two ends of the protrusion 213. This allows the second engaging portion 212 to be pushed out of the first limiting groove 33 and into the receiving portion 34, which facilitates the engagement between the second engaging portion 212 and the first stop portion 31. Furthermore, the second snap-fit ​​portion 212 has a tendency to return to its original position after elastic deformation, that is, its extended length has a tendency to shorten and recover, which causes the second snap-fit ​​portion 212 to be subjected to tension, increasing the compressive force between the second snap-fit ​​portion 212 and the first stop portion 31, making the second snap-fit ​​portion 212 and the first stop portion 31 snap-fit ​​more tightly.

[0042] In one embodiment, the second connecting portion 22 is fixedly connected to the end of the first component A near the second component B.

[0043] like Figure 2 and Figure 4 As shown, specifically, the second connecting part 22 has at least two through holes 221. The end of the first component A near the second component B has a protrusion 11 corresponding to the through hole 221. The through hole 221 is fitted onto the outside of the protrusion 11, and the protrusion 11 is fixedly connected to the second connecting part 22. The protrusion 11 and the through hole 221 are correspondingly positioned and fitted, which better limits the movement of the coil component 1 and the second connecting part 22, thus improving structural stability. The protrusion 11 and the through hole 221 can be fixedly connected by riveting or welding.

[0044] In one embodiment, the first component A is a coil component 1, the second component B is a valve body 3, and the valve device further includes a valve seat 4, which is located between the coil component 1 and the valve body 3. The valve seat 4 includes a valve sleeve 41, a valve cover 42, and a valve core assembly 44. The coil component 1 is sleeved outside the valve sleeve 41, and the valve sleeve 41 is sleeved outside the valve core assembly 44. The second wall surface 35 has a mounting cavity 351, at least part of the valve cover 42 and the valve core assembly 44 are located in the mounting cavity 351, and the valve cover 42 is connected to the valve body 3.

[0045] like Figure 2As shown, optionally, the second connecting part 22 is an annular structure, with a hollow annular structure to accommodate the valve seat 4, allowing the valve seat 4 to pass through the second connecting part 22. The valve body 3 has a mounting cavity 351 on the second wall surface 35. A portion of the valve seat 4 passes through the mounting cavity 351 and is detachably connected to the valve body 3. The valve core assembly 44 can control the flow path in the valve body 3 by energizing or de-energizing the coil component 1. Another portion of the valve seat 4 protrudes from the second wall surface 35 and is fitted inside the coil component 1. Specifically, the valve cover 42 is located at the end of the valve seat 4 near the valve body 3, and the valve cover 42 is detachably connected to the wall forming the mounting cavity 351. Optionally, the two are connected by threads, ensuring reliable connection and convenient operation. In other embodiments, the valve device also includes a pad 43, located at the end face of the valve cover 42 away from the valve body 3, for supporting the coil component 1; and a valve sleeve 41 is located at the end of the valve cover 42 away from the valve body 3, and is fitted inside the coil component 1.

[0046] This utility model provides a coil device, including a coil component 1 and a connector 2. The connector 2 is fixedly connected to the coil component 1. The connector 2 includes a first connecting part 21, the first connecting part 21 includes a second snap-fit ​​part 212 and a limiting part 211. The limiting part 211 extends along the axial direction of the coil component 1. The second snap-fit ​​part 212 is located at the end of the limiting part 211 away from the coil component 1. The limiting part 211 has an elastic structure, and the angle between the limiting part 211 and the axial direction of the coil component 1 can be adjusted.

[0047] The angle between the limiting part 211 and the coil component 1 in the axial direction is between 0 and 90 degrees to improve the adaptability of the assembly angle of the connector 2 and to change the angle to change the restoring force of the limiting part 211 after being squeezed and tilted. For example, as Figure 7 As shown, the angle between the limiting part 211 and the axial direction of the coil component 1 is 0 degrees, and the angle between the limiting part 211 and the plane perpendicular to plane P is α2; for example, as Figure 8 As shown, the angle between the limiting part 211 and the axial direction of the coil component 1 is 30 degrees, and the angle between the limiting part 211 and the plane perpendicular to the plane P is α1. After being squeezed, the angle between the limiting part 211 and the axial direction of the coil component 1 is less than α1, for example, it becomes 0 degrees, and α1 decreases to α2. The greater the difference in the angle, the greater the restoring force of the limiting part 211.

[0048] It should be noted that the above-described embodiments only illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be pointed out that those skilled in the art can make several modifications without departing from the concept of this utility model, and these modifications all fall within the protection scope of this utility model.
