[0038] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

If the specific posture changes, the directional indication will also change accordingly.

[0040] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0042] The first aspect of the present application provides a solenoid valve coil assembly 1000, which will be described below in conjunction with the solenoid valve 100. Figure 1 and Figure 2 As shown, in some embodiments of the present application, the solenoid valve coil assembly 1000 includes a coil 1110 and a magnetic conductor 1300 . The coil 1110 is used to surround the static iron core, and the magnetic conductor 1300 is used to enclose the coil 1110 .

[0043] In this embodiment, the magnet 1300 encloses the coil 1110, that is, the coil 1110 is wrapped by the magnet 1300 on all four sides. Through such a setting, the coil 1110 can generate a stronger magnetic field strength when energized, thereby increasing the driving force of the solenoid valve 100. Compared with the open setting of the magnet 1300 in the prior art, in this embodiment, under the same voltage, the driving force of the solenoid valve 100 is significantly increased, and under the same driving force, the voltage required for the solenoid valve 100 to operate is lower. By enclosing the coil 1110 with the magnet 1300, the operating performance of the solenoid valve 100 can be significantly improved.

[0044] Specifically, the basic structure of the solenoid valve 100 is as follows: the solenoid valve 100 includes a valve cover, a valve seat, a piston component, a housing, a moving iron core component, a static iron core component and a solenoid valve coil assembly 1000. The valve seat is provided with a valve port. The valve cover and the valve seat are connected together to enclose a valve cavity. The piston component is movably arranged in the valve cavity. The housing, the moving iron core and the static iron core are assembled together and fixed to the valve cover. The solenoid valve coil assembly 1000 is sleeved on the static iron core component. When the solenoid valve coil assembly 1000 is energized, When the solenoid valve coil assembly 1000 is powered on, the static iron core can be magnetized, and when the solenoid valve coil assembly 1000 is powered off, the static iron core can drive the moving iron core to move back and forth, and the reciprocating movement of the moving iron core can drive the piston component to move back and forth axially in the valve cavity. The reciprocating movement of the piston component can close and open the valve port. When the piston component opens the valve port, the solenoid valve 100 is in a connected state, and when the piston component closes the valve port, the solenoid valve 100 is in a disconnected state.

[0045] It is understandable that the above is merely an exemplary description of the solenoid valve 100 and does not constitute a limitation on the structure of the solenoid valve 100 .

[0046] In order to improve the operating performance of the solenoid valve 100, in this embodiment, the magnet 1300 is designed to enclose the coil 1110. The so-called enclosure means that the coil 1110 is surrounded by the magnet 1300 on all sides. Compared with the open design of the magnet 1300 in the related art (that is, the coil 1110 is not completely surrounded by the magnet 1300 on all sides), the magnet 1300 in this embodiment encloses the coil 1110, so that a greater magnetic field strength is generated when the coil 1110 is energized, thereby increasing the force of the static iron core on the moving iron core, that is, increasing the driving force of the solenoid valve 100, which is beneficial to improving the operating performance of the solenoid valve 100.

[0047] Combine Figure 3 、 Figure 4 and Figure 5As shown, in some embodiments of the present application, the magnetizer 1300 includes at least two parts connected and fixed by a connection means. As can be seen from the above, the magnetizer 1300 needs to wrap around the coil 1110 on all sides. In order to facilitate the assembly of the coil 1110 and the magnetizer 1300, in this embodiment, the magnetizer 1300 includes at least two parts, for example, the magnetizer 1300 includes two parts, three parts, four parts, five parts or six parts, and the parts are connected and fixed by a connection means. Taking the magnetizer 1300 as an example, when assembling the magnetizer and the coil 1110, a part of the magnetizer 1300 can be assembled with the coil 1110 first, and then the other part of the magnetizer 1300 can be connected to the aforementioned part of the magnetizer 1300. This can not only facilitate the assembly of the magnetizer 1300 and the coil 1110, but also achieve the magnetizer 1300 enclosing the coil 1110.

[0048] Combine Figure 2 and Figure 3 As shown, in some embodiments of the present application, the magnetic conductor 1300 includes a surrounding plate 1330, a first plate 1310 and a second plate 1320. The first plate 1310 is arranged at one end of the surrounding plate 1330, and the second plate 1320 is arranged at the other end of the surrounding plate 1330. The surrounding plate 1330 surrounds the coil 1110 along the circumference of the coil 1110. Through such cooperation, the surrounding plate 1330, the first plate 1310 and the second plate 1320 jointly achieve the enclosure of the coil 1110.

[0049] Specifically, since the coil 1110 needs to surround the static iron core, the coil 1110 is generally cylindrical, the extension direction of the static iron core is axial, and the direction surrounding the static iron core is circumferential. In this embodiment, by designing the enclosure 1330, the enclosure 1330 realizes the surrounding of the coil 1110 along the circumference of the coil 1110, that is, the enclosure 1330 surrounds the central axis of the coil 1110, realizing the circumferential wrapping of the coil 1110, and the first plate 1310 and the second plate 1320 are respectively located in the axial direction of the coil 1110, realizing the wrapping of the coil 1110 in the axial direction of the coil 1110. The enclosure 1330, the first plate 1310 and the second plate 1320 can cooperate to better adapt to the overall shape of the coil 1110, and together realize a more compact wrapping of the coil 1110. The first plate 1310 can be provided with a mounting hole 1311. When the solenoid valve coil assembly 1000 is applied to the solenoid valve 100, and the solenoid valve 100 is applied to the refrigeration equipment 200, the mounting hole 1311 can be used for fixing external components, thereby improving the installation stability of the solenoid valve 100. The second plate 1320 can be provided with a second connecting hole 1321. The solenoid valve coil assembly 1000 can be mounted outside the static iron core through the second connecting hole 1321.

[0050] Under the premise that the magnetic conductor 1300 includes the surrounding plate 1330 , the first plate 1310 and the second plate 1320 , there are multiple ways to assemble the magnetic conductor 1300 and the coil 1110 .

[0051] Can be combined Figure 4 As shown, the first plate 1310 and the enclosure 1330 need to be connected and fixed by connecting means, and the second plate 1320 and the enclosure 1330 also need to be connected and fixed by connecting means. When assembling the magnetic conductor 1300 and the coil 1110, the first plate 1310 and the enclosure 1330 can be connected and fixed first. The structure formed by the connection and fixing of the first plate 1310 and the enclosure 1330 forms an opening, and the coil 1110 can be installed thereon through the opening. Finally, the second plate 1320 is connected, thereby achieving the enclosure of the magnetic conductor 1300 around the coil 1110.

[0052] It can also be combined with Figure 5 and Figure 6 As shown, one of the first plate 1310 and the second plate 1320 is integrally formed with the enclosure 1330, while the other of the first plate 1310 and the second plate 1320 is connected and fixed to the enclosure 1330 by a connecting means. The first plate 1310 and the enclosure 1330 are connected and fixed by a connecting means, and the second plate 1320 and the enclosure 1330 are integrally formed as an example for explanation. The second plate 1320 and the enclosure 1330 are integrally formed, that is, when the second plate 1320 and the enclosure 1330 are manufactured, the two form a single body, rather than being connected by additional connecting means. The second plate 1320 and the enclosure 1330 can be integrally formed by stamping, stretching, casting, or the like. In this case, the structure formed by the second plate 1320 and the enclosure 1330 has an opening, and the coil 1110 is installed through the opening. Finally, the first plate 1310 is connected to enclose the coil 1110.

[0053] It can also be combined with Figure 7As shown, the enclosure 1330 includes at least two parts, and the parts are connected and fixed by connecting means. For example, the enclosure 1330 includes two parts, three parts, or four parts, and the parts are connected and fixed by connecting means to form the enclosure 1330. Taking the enclosure 1330 as an example, when assembling the magnetic conductor 1300 and the coil 1110, the first plate 1310 can be connected to a part of the enclosure 1330, the second plate 1320 can be connected to the other part of the enclosure 1330, the coil 1110 can be installed on one of the two parts, and finally the parts of the enclosure 1330 are connected, thereby enclosing the coil 1110. Of course, the first plate 1310 and a part of the enclosure 1330 can also form an integrally formed structure, and the second plate 1320 and another part of the enclosure 1330 can also form an integrally formed structure. This is conducive to improving assembly efficiency, and there is no need to perform subsequent connection operations on the first plate 1310 and the enclosure 1330, and the second plate 1320 and the enclosure 1330.

[0054] The enclosure 1330 can be annular or non-annular as a whole. Since the coil 1110 is cylindrical as a whole, when the enclosure 1330 is annular, it can be closer to the coil 1110 and make full use of the space. When the enclosure 1330 is non-annular, such as a square ring, the fixation between the coil 1110 and the magnet 1300 is also simpler, and the coil 1110 is not easy to rotate relative to the magnet 1300 along its circumference. Figure 3 and Figure 4 As shown, when the enclosure 1330 is a square ring, the enclosure 1330 includes a first enclosure 1331, a second enclosure 1332, a third enclosure 1333 and a fourth enclosure 1334. The first enclosure 1331, the second enclosure 1332, the third enclosure 1333 and the fourth enclosure 1334 can be connected and fixed to each other by connection means, or can be an integrally formed structure.

[0055] The aforementioned connection means can be achieved in a variety of ways, such as welding or snap-fit ​​connection, which facilitates the assembly of the magnetizer 1300 and ensures a certain degree of connection stability. For example, the second plate 1320 and the enclosure 1330 form an integrally formed structure. When assembling the coil 1110 and the magnetizer 1300, the coil 1110 is first installed on the structure formed by the second plate 1320 and the enclosure 1330, and finally the first plate 1310 is connected to the enclosure 1330. The first plate 1310 and the enclosure 1330 are fixed by welding or snap-fit ​​connection, thereby achieving the magnetizer 1300 enclosing the coil 1110.

[0056] Combine Figure 1 、 Figure 2 and Figure 3As shown, in some embodiments of the present application, the solenoid valve coil assembly 1000 further includes a plastic coating layer 1130, which wraps the coil 1110. Through the provision of the plastic coating layer 1130, the plastic coating layer 1130 substantially isolates the coil 1110 from the outside world, prevents the coil 1110 from being damaged, and ensures the operational stability of the solenoid valve 100. The plastic coating layer 1130 can be understood as a structure that covers the coil 1110 and is used to isolate the coil 1110 from the outside world. The plastic coating layer 1130 can be made of various materials, such as plastic. Generally speaking, the coil 1110 is first wound around the bracket 1120, and then the plastic coating layer 1130 is provided to wrap the coil 1110 and the bracket 1120.

[0057] During the molding process of the overmolding layer 1130 surrounding the coil 1110, a connector 1200 is formed simultaneously. The connection end 1111 of the coil 1110 is located within the connector 1200. The connector 1200 is plugged into the power supply component to supply power to the coil 1110. Since the magnetizer 1300 needs to enclose the coil 1110, the overmolding layer 1130 is also enclosed by the magnetizer 1300 when the magnetizer 1300 and coil 1110 are assembled. A first connecting hole 1335 is provided in the magnetizer 1300, through which the connector 1200 is exposed, facilitating connection with the power supply component. The first connecting hole 1335 also serves as a stop for the connector 1200, preventing excessive movement of the connector 1200 that could break the connection end 1111 of the coil 1110.

[0058] Further, combined with Figure 2 As shown, in some embodiments of the present application, when the magnetic conductor 1300 encloses the plastic-coated layer 1130, the plastic-coated layer 1130 abuts against the enclosure 1330, the first plate 1310, and the second plate 1320. Specifically, the plastic-coated layer 1130 abuts against the inner wall of the enclosure 1330, the inner wall of the first plate 1310, and the inner wall of the second plate 1320. In this way, the magnetic conductor 1300 forms a limit for the plastic-coated layer 1130, and the coil 1110 is not easy to rotate, thereby effectively achieving the fixation of the coil 1110, which is convenient and quick.

[0059] The second aspect of the present application discloses a solenoid valve 100, Figures 1 to 8As shown, the solenoid valve 100 includes the solenoid valve coil assembly 1000 of the above embodiment, and the solenoid valve coil assembly 1000 is sleeved on the static iron core of the solenoid valve 100, for example, the solenoid valve coil assembly 1000 is sleeved on the static iron core through its second connecting hole 1321. The solenoid valve coil assembly 1000 includes a coil 1110 and a magnetic conductor 1300. The coil 1110 is used to surround the static iron core, while the magnetic conductor 1300 is used to enclose the coil 1110. That is, the coil 1110 is surrounded by the magnetic conductor 1300 on all sides. With this arrangement, the coil 1110 can generate a stronger magnetic field when energized, thereby increasing the driving force of the solenoid valve 100. Compared with the open arrangement of the magnetic conductor 1300 in the prior art, this embodiment significantly increases the driving force of the solenoid valve 100 under the same voltage. When providing the same driving force, the voltage required for the solenoid valve 100 to operate is lower. By enclosing the coil 1110 by the magnetic conductor 1300, the operating performance of the solenoid valve 100 can be significantly improved. It can be understood that the solenoid valve coil assembly 1000 of the solenoid valve 100 adopts the technical solutions of the above-mentioned embodiments and therefore has at least the beneficial effects brought about by the technical solutions of the above-mentioned embodiments. The details will not be repeated here.

[0060] The third aspect of the present application discloses a refrigeration device 200, Figures 1 to 9 As shown, the refrigeration equipment 200 includes the solenoid valve 100 of the above embodiment, and the solenoid valve 100 includes a solenoid valve coil assembly 1000. The solenoid valve coil assembly 1000 includes a coil 1110 and a magnet 1300. The coil 1110 is used to surround the static iron core, and the magnet 1300 is used to enclose the coil 1110, that is, the coil 1110 is wrapped by the magnet 1300 on all sides. Through such a setting, the coil 1110 can generate a stronger magnetic field strength when energized, thereby increasing the driving force of the solenoid valve 100. Compared with the open setting of the magnet 1300 in the prior art, the driving force of the solenoid valve 100 in this embodiment is significantly increased under the same voltage, and under the same driving force, the voltage required for the solenoid valve 100 to operate is lower. By enclosing the coil 1110 with the magnet 1300, the operating performance of the solenoid valve 100 can be significantly improved.

[0061] The solenoid valve 100 is used to control the flow of a medium in a refrigeration device 200. For example, the refrigeration device 200 includes an integrated module (not shown in the figure), which is provided with a mounting cavity (not shown in the figure). The solenoid valve 100 is installed in the mounting cavity, thereby controlling the flow of the medium in the flow path. Of course, the refrigeration device 200 in this embodiment is not limited to this. As long as the solenoid valve 100 can achieve flow control of the medium. It is understandable that the solenoid valve 100 of the refrigeration device 200 adopts the technical solution of the above-mentioned embodiment, and therefore has at least the beneficial effects brought about by the technical solution of the above-mentioned embodiment, which will not be repeated here.

[0062] The fourth aspect of the present application discloses a car 300, Figures 1 to 10 As shown, the automobile 300 includes the above-mentioned refrigeration equipment 200. The automobile 300 can be a new energy automobile 300. The new energy automobile 300 can be a pure electric automobile 300 with an electric motor as the main driving force. The new energy automobile 300 can also be a hybrid electric automobile 300 with an internal combustion engine and an electric motor as the main driving force. The internal combustion engine and the electric motor that provide driving power for the new energy automobile 300 can use gasoline, diesel, hydrogen, etc. as fuel, and the method of providing electrical energy to the electric motor can use power batteries, hydrogen fuel cells, etc., which are not specifically limited here. It should be noted that this is only an exemplary description of the structure of the new energy automobile 300, etc., and is not intended to limit the scope of protection of the present invention / utility model. Since the refrigeration equipment 200 of the automobile 300 adopts the technical solution of the above-mentioned embodiment, it at least has the beneficial effects brought about by the technical solution of the above-mentioned embodiment, and will not be repeated here.

[0063] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application.
