[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work 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 clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0041] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. 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 , wherein 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, and the solenoid valve coil assembly 1000 is energized. The static iron core can be magnetized when the solenoid valve coil assembly 1000 is powered on, and can be demagnetized when the solenoid valve coil assembly 1000 is powered on and off. By energizing and deenergizing the solenoid valve coil assembly 1000, the static iron core can drive the moving iron core to reciprocate, and the reciprocating movement of the moving iron core can drive the piston component to reciprocate 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 the present 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 encloses the coil 1110 in the present embodiment. In this way, 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] Combination 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 connecting means. As can be seen from the above, the magnetizer 1300 needs to wrap 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 connecting means. Taking the magnetizer 1300 including two parts 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, so that it can facilitate the assembly of the magnetizer 1300 and the coil 1110, and also realize that the magnetizer 1300 encloses the coil 1110.

[0048] Combination 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, and 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 realize 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 to realize 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, and the coil 1110 is wrapped 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 may 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 may be used for fixing external components, thereby improving the installation stability of the solenoid valve 100. The second plate 1320 may be provided with a second connecting hole 1321. The solenoid valve coil assembly 1000 may be mounted outside the static iron core through the second connecting hole 1321.

[0050] On the premise that the magnetic conductor 1300 includes the enclosure 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] It can be combined with 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 magnetizer 1300 and the coil 1110, the first plate 1310 and the enclosure 1330 can be connected and fixed first, and 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, and finally the second plate 1320 is connected, so that the magnetizer 1300 can enclose 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 an integrally formed structure with the enclosure 1330, and the other of the first plate 1310 and the second plate 1320 is connected and fixed to the enclosure 1330 by means of connection. Take the first plate 1310 and the enclosure 1330 as an example in which the second plate 1320 and the enclosure 1330 are connected and fixed by means of connection, and the second plate 1320 and the enclosure 1330 are an integrally formed structure. 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 whole, rather than being connected by additional connection means. The second plate 1320 and the enclosure 1330 can be integrally formed by stamping, stretching, casting, etc. At this time, the structure formed by the second plate 1320 and the enclosure 1330 has an opening, and the coil 1110 is installed through the opening, and finally the first plate 1310 is connected to achieve the enclosure of 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 including two parts as an example, when assembling the magnetizer 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 another part of the enclosure 1330, the coil 1110 can be installed on one of the two, and finally the parts of the enclosure 1330 are connected, so as to achieve the enclosure of the coil 1110. Of course, the first plate 1310 and a part of the enclosure 1330 may also form an integrally formed structure, and the second plate 1320 and another part of the enclosure 1330 may also form an integrally formed structure. This is beneficial for improving assembly efficiency, and there is no need to subsequently connect 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. Since the coil 1110 is cylindrical, 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 magnetizer 1300 is also simpler, and the coil 1110 is not easy to rotate relative to the magnetizer 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 interconnected and fixed by connecting means, or can be an integrally formed structure.

[0055] There are many ways to achieve the connection means mentioned above, which can be welding or snap connection, so that it is convenient to assemble the magnetizer 1300 and ensure a certain connection stability. For example, the second plate 1320 and the enclosure 1330 form an integrated 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, and the first plate 1310 and the enclosure 1330 are fixed by welding or snap connection, so that the magnetizer 1300 encloses the coil 1110.

[0056] Combination 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 setting of the plastic coating layer 1130, the plastic coating layer 1130 basically isolates the coil 1110 from the outside world, prevents the coil 1110 from being damaged, and ensures the working stability of the solenoid valve 100. The plastic coating layer 1130 can be understood as a structure that covers the coil 1110, which is used to isolate the coil 1110 from the outside world. The plastic coating layer 1130 can be made of a variety of materials, such as a plastic coating layer 1130 made of plastic. Generally speaking, the coil 1110 is first wound on the bracket 1120, and then the plastic coating layer 1130 is set to wrap the coil 1110 and the bracket 1120.

[0057] The plastic coating 1130 is formed with a plug 1200 during the process of encapsulating the coil 1110. The connection end 1111 of the coil 1110 is located in the plug 1200. The plug 1200 is plugged into the plug of the power supply component, so that the coil 1110 can be powered. Since the magnetizer 1300 needs to enclose the coil 1110, when the magnetizer 1300 and the coil 1110 are assembled, the plastic coating 1130 is also enclosed by the magnetizer 1300. The magnetizer 1300 is provided with a first connecting hole 1335, and the plug 1200 passes through the first connecting hole 1335 and is exposed to the outside, so that it is convenient to plug in with the plug of the power supply component. In addition, through the provision of the first connecting hole 1335, a limit can be formed with the plug 1200 to prevent the plug 1200 from moving too much and causing the connection end 1111 of the coil 1110 to break.

[0058] Furthermore, combined with Figure 2 As shown, in some embodiments of the present application, when the magnetic conductor 1300 surrounds 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 realizing 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 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 surrounded by the magnet 1300 on all sides. By such a setting, the coil 1110 can generate a stronger magnetic field strength when it is 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 is significantly increased under the same voltage in this embodiment, and the voltage required for the solenoid valve 100 to operate is lower under the same driving force. By enclosing the coil 1110 with the magnet 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 solution of the above embodiment, and therefore at least has the beneficial effects brought by the technical solution of the above embodiment, which 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, and 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 surrounded 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, under the same voltage, the driving force of the solenoid valve 100 in this embodiment 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.

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

[0062] A fourth aspect of the present application discloses a vehicle 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, and the new energy automobile 300 can be a pure electric automobile 300 with a motor as the main driving force, and the new energy automobile 300 can also be a hybrid electric automobile 300 with an internal combustion engine and a motor as the main driving force at the same time. The internal combustion engine and the motor that provide driving power for the new energy automobile 300 mentioned above, wherein the internal combustion engine can use gasoline, diesel, hydrogen, etc. as fuel, and the way to provide electric energy for the 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 it does not 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 by the technical solution of the above-mentioned embodiment, and will not be repeated here.
