[0085] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0086] Refer to Figures 1 to 13 As shown, for the convenience of introduction, the upper, lower, left, right, front, and rear orientations are adopted in the corresponding drawings to facilitate the introduction of the relative positional relationship between the various parts in the present application, and it should not be construed as a limitation on the absolute position.

[0087] According to the first aspect of the present application, with reference to Figures 1 to 13 , an electronically controlled valve assembly is provided, including a base body 200, a valve core 501, and an electromagnetic device 100.

[0088] The base body 200 is formed with a plurality of working fluid flow paths 202 and a plurality of valve body cavities 203. A part of the valve core 501 is disposed in the valve body cavity 203, and the electromagnetic device 100 is used to generate a magnetic field acting on the valve core 501.

[0089] Wherein, the valve body cavity 203 is communicated with the working fluid flow path 202 so that the valve core 501 controls the on-off of the working fluid flow path 202. The electromagnetic device 100 is provided with a plurality of drive interfaces for respectively docking different valve cores 501 to provide independent magnetic fields for different valve cores 501.

[0090] Through the above technical solution, the integrated electromagnetic device 100 solves the problem of complex plug-in cables. At the same time, the base body 200 integrating multiple flow paths simplifies the flow path relationship, and the overall structure has a high integration degree, which is convenient for assembly and installation.

[0091] With reference to Figure 2 , two valve cores 501 can be arranged to be communicated with one working fluid flow path 202.

[0092] With reference to Figure 13 , the valve core 501 and the working fluid flow path 202 can be arranged to be in one-to-one correspondence and communication. In this arrangement, the valve cores 501 are arranged in a straight line, which can reduce the flow resistance of the system, and the working fluid flow paths 202 are arranged on the side surface, on the surface perpendicular to the base body 200, which can avoid the use of plug covers and reduce the risk of leakage of the integrated module.

[0093] With reference to Figure 6 , the working fluid flow path 202 can also be arranged on the bottom surface of the base body 200 to simplify the pipeline layout and avoid interference with the valve core and other components of the vehicle.

[0094] After the electromagnetic field generates a magnetic field, it can energize the valve core 501 so that the valve core 501 can control the on-off of the working fluid flow path 202.

[0095] In some embodiments, with reference to Figures 1 to 3 , the electronically controlled valve assembly 10 further includes a shock pad 301.

[0097] By providing an installation groove 204 on the base body 200 that is isolated from the working fluid flow path 202, the shock-absorbing pad 301 is embedded in the base body 200. The shock-absorbing pad 301 can absorb the vibrations generated by the base body 200, preventing excessive vibrations of the base body 200. The shock-absorbing pad 301 is installed in an interference fit with the base body 200.

[0098] Reference Figure 2 , an installation groove 204 can be provided on one side surface of the base body 200, and two installation grooves 204 can be provided on the opposite side surface. Correspondingly, one shock-absorbing pad 301 is provided on one side surface, and two shock-absorbing pads 301 are provided on the other side surface.

[0099] By setting different numbers of shock-absorbing pads 301, it can serve as a reminder for installers and also prevent misinstallation.

[0101] The fixing bolts are fixedly connected to the shock-absorbing pad 301.

[0102] Among them, at least a part of the installation bolt 600 is exposed outside the shock-absorbing pad 301.

[0103] Using the installation bolt 600, the operation is convenient. The bolt can install the base body 200 onto the vehicle bracket, facilitating the overall installation.

[0104] In some embodiments, the electromagnetic device 100 includes a plurality of magnetic bodies 103, an upper cover 101, and a lower cover 104.

[0105] Each magnetic body 103 respectively encloses an independent accommodation space. The upper cover 101 forms a space for accommodating the magnetic bodies 103, and the lower cover 104 is used to encapsulate the magnetic bodies 103 in the space of the upper cover 101.

[0106] Among them, the accommodation space is provided to be exposed from the lower cover 104.

[0107] By energizing and de-energizing the magnetic bodies 103, the generation of an electromagnetic field is achieved, which acts on the valve core 501 to achieve the opening and closing of the working fluid flow path 202.

[0108] By providing the accommodation space to be exposed from the lower cover 104, at least a part of the valve core 501 can be arranged in the accommodation space.

[0109] Exemplarily, the magnetic body 103 can be configured as an electromagnetic coil, and the drive interface of the electromagnetic device is the pin of the electromagnetic coil.

[0110] The arrangement of the magnetic bodies 103 on the base body 200 can be configured as a straight line, a rectangle, or an arc.

[0111] The upper cover 101 and the lower cover 104 are connected by connecting bolts 102.

[0112] In some embodiments, the electromagnetic device 100 further includes a sealing ring 105.

[0113] The sealing ring is arranged between the upper cover and the lower cover for sealing the gap between the upper cover and the lower cover.

[0114] By providing the sealing ring 105, electrical protection is provided for the electronic control valve assembly to prevent corrosion by external dust, water vapor and electromagnetic crosstalk.

[0115] In some embodiments, the electromagnetic device 100 further includes a terminal block 106.

[0116] The terminal block 106 is used to electrically connect the electromagnetic coil to the outside. Among them, at least part of the terminal block 106 is accommodated in the space of the upper cover 101, and the upper cover 101 is formed with a terminal interface 101a for exposing the terminal block 106.

[0117] Using one terminal block 106 can complete the energization of all the magnetic bodies 103, that is, the energization of the electromagnetic coil, with a high degree of integration.

[0118] In some embodiments, referring to Figure 13 , the electronic control valve assembly includes a buckle 400.

[0119] By providing the buckle 400, the valve core 501 can be clamped to the base body 200.

[0120] In some embodiments, the buckle 400 includes a snap ring 401 and a latch 402.

[0121] The snap ring 401 can be sleeved on the valve core 501, and the latch 402 is used to fix the snap ring 401 to the base body 200.

[0122] The latch 402 has at least one hook 403.

[0123] Adopting the buckle 400 to clamp the valve core 501 to the base body 200 has a stable connection method and is convenient for molding.

[0124] In some embodiments, the valve core 501 is the valve core of the control valve 500, which is convenient to operate.

[0125] In some embodiments, the control valve 500 is one of an electronic expansion valve and a solenoid valve.

[0126] Exemplarily, if the number of the control valves 500 is set to four, the number of the valve cores is also four.

[0127] Among the four control valves, the control valves can all be set as electronic expansion valves, or all be set as solenoid valves, or two control valves be electronic expansion valves and two control valves be solenoid valves.

[0128] Adopting the valve core 501 as the valve core 501 of the electromagnetic expansion valve 500 is convenient for operation.

[0129] In some embodiments, at least part of the working medium flow path 202 extends in a direction perpendicular to the direction in which the valve core 501 is inserted into the valve body cavity 203.

[0130] By extending at least part of the working medium flow path 202 in a direction perpendicular to the direction in which the valve core 501 is inserted into the valve body cavity 203, it is convenient to arrange in the same direction.

[0131] Exemplarily, all of the working medium flow path 202 extends and is arranged in a direction perpendicular to the direction in which the valve core 501 is inserted into the valve body cavity 203.

[0132] In some embodiments, the drive interface can be installed in a suitable receiving space, and the drive interface is electrically connected to the terminal block, so that the magnetic body 103 can be electrically connected to the outside.

[0133] By integrating the terminal block 106 of the electromagnetic device into the terminal interface of the upper cover 101, the on / off of the magnetic body 103 can be realized by controlling the on / off of the electricity of the terminal block, so as to provide an independent magnetic field for different valve cores 501, and the degree of integration is high.

[0134] Exemplarily, the pins are installed in a suitable receiving space, and the terminal block is electrically connected to the pins in the receiving space.

[0135] In some embodiments, the center lines of at least two valve cores 501 are located in the same plane.

[0136] Reference Figure 13 , the valve cores are set to four. From left to right, the center lines of the four valve cores 501 are all located in the same plane, that is, the arrangement direction of the valve cores is a straight line. Arranging the valve cores on the same straight line can reduce the flow resistance of the system.

[0137] In some other embodiments, the valve cores 501 can also be set to four. Referring to Figure 2 , the center lines of two valve cores 501 are located in the same plane, and the four valve cores 501 form a matrix.

[0138] Exemplarily, when the four valve cores 510 form a matrix, referring to Figures 4 to 10, multiple working fluid flow paths are provided, namely the first working fluid flow path 2021, the second working fluid flow path 2022, the third working fluid flow path 2023, the fourth working fluid flow path 2024, the fifth working fluid flow path 2025, the sixth working fluid flow path 2026, the seventh working fluid flow path 2027, and the eighth working fluid flow path 2028.

[0139] Among them, the first working fluid flow path 2021 and the second working fluid flow path 2022 are arranged on the first surface of the base body 200, the third working fluid flow path 2023 and the fourth working fluid flow path 2024 are arranged on the second surface of the base body 200, and the fifth working fluid flow path 2025, the sixth working fluid flow path 2026, the seventh working fluid flow path 2027, and the eighth working fluid flow path 2028 are opened on the base body 200 along the third surface of the base body 200.

For example, the third surface can be the lower surface of the base body 200.

[0141] Exemplarily, referring to Figure 13 , when the centerlines of the four valve cores 501 are all located in the same plane, that is, when the arrangement direction of the valve cores is a straight line, the first to fourth working fluid flow paths adapted to the four valve cores 501 can all be arranged on the same surface, such as the front surface, and the fifth to eighth working fluid flow paths can all be arranged on the same surface, such as the lower surface.

[0142] Adaptively, referring to Figure 3 and Figure 13 , four electronic expansion valves are provided, namely the electronic expansion valve 21, the electronic expansion valve 22, the electronic expansion valve 23, and the electronic expansion valve 24.

[0143] Multiple adapted flow channels 205 are provided. Exemplarily, four flow channels 205 are provided in the present application, namely the first flow channel 2051, the second flow channel 2051, the third flow channel 2053, and the fourth flow channel 2054.

[0144] The fifth working fluid flow path 2025, the sixth working fluid flow path 2026, the seventh working fluid flow path 2027, and the eighth working fluid flow path 2028 are directly communicated with the valve body cavity. No flow channels are provided between the fifth working fluid flow path 2025, the sixth working fluid flow path 2026, the seventh working fluid flow path 2027, and the eighth working fluid flow path 2028 and the valve body cavity.

[0145] Of course, flow channels can also be provided between the fifth working fluid flow path 2025, the sixth working fluid flow path 2026, the seventh working fluid flow path 2027, the eighth working fluid flow path 2028 and the valve body cavity. In this application, an example is given where no flow channels are provided.

[0146] The specific adaptation of the working fluid flow path and the adaptation of the working fluid flow path to the electronic expansion valve and the flow channel can be set according to the actual system, and will not be elaborated here.

[0147] According to the second aspect of the present application, referring to Figure 13 , a thermal management system 1 is provided. The heat exchange management system includes an electronically controlled valve assembly 10 and a refrigerant channel, and the refrigerant channel can be connected to the working fluid flow path of the electronically controlled valve assembly 10. This thermal management system has all the beneficial effects of the above-mentioned electronically controlled valve assembly, which will not be elaborated here in this application.

[0148] The thermal management system 1 of the present application includes a refrigerant side integration module, and the refrigerant side integration module includes: an electronically controlled valve assembly and a refrigerant channel.

[0149] The refrigerant side integration module can achieve 4 single working modes: air conditioning refrigeration mode, air conditioning heating mode, battery cooling mode, and battery heating mode.

[0150] Specifically, the following describes the 4 single working modes.

[0151] Mode 1: Air conditioning refrigeration mode

[0152] In the automotive air conditioning refrigeration mode, referring to Figure 14 , the compressor 250 discharges high-temperature and high-pressure gaseous refrigerant, which enters the out-of-vehicle condenser 220. The refrigerant releases heat and liquefies in the out-of-vehicle condenser 220 to become a medium-temperature and high-pressure liquid. The pipeline connects the fourth working fluid flow path 2024 of the base body 200 and enters the valve body cavity 203, and then enters the electronic expansion valve 24 through the fourth flow channel 2054 for throttling and expansion. The low-temperature and low-pressure gas-liquid mixture flowing through the throttling and expansion of the electronic expansion valve 24 flows along the valve body cavity 203 to the eighth working fluid flow path 2028. The eighth working fluid flow path 2028 is connected to the evaporator 230 through a pipeline. Then, the high-temperature and high-pressure gaseous refrigerant flowing out of the eighth working fluid flow path 2028 enters the evaporator 230 along the pipeline to absorb heat and evaporate, that is, absorb the heat in the environment, so that the temperature of the passenger compartment drops. The low-temperature and low-pressure gas enters the gas-liquid separator 270 and the compressor 250 through an external pipeline for air conditioning refrigeration cycle operation.

[0153] Mode 2: Air conditioning heating mode

[0154] In the automotive heating mode, referring to Figure 14, the refrigerant flowing out of the compressor 250 enters the in-vehicle condenser 210 through pipeline connection. The refrigerant releases heat in the in-vehicle condenser 210, and hot air is blown into the vehicle through the blower to heat the vehicle. The refrigerant coming out of the in-vehicle condenser 210 enters the third working fluid flow path 2023 through a pipeline, and enters the electronic expansion valve 23 along the third flow path 2053 for throttling and expansion. The low-temperature and low-pressure gas-liquid mixture flowing through the electronic expansion valve 23 flows to the seventh working fluid flow path 2027 along the valve body cavity 203. The seventh working fluid flow path 2027 is connected to the plate heat exchanger 260 through a pipeline. Then, the low-temperature and low-pressure gas-liquid mixture flowing out of the seventh working fluid flow path 2027 enters the plate heat exchanger 260 to absorb heat and evaporate into a low-temperature and low-pressure gas, and then enters the gas-liquid separator 270 and the compressor 250 through an external pipeline to perform the air-conditioning heating cycle operation.

[0155] Mode 3: Battery cooling mode

[0156] In the automotive battery cooling mode, refer to Figure 14 , the compressor 250 discharges high-temperature and high-pressure gaseous refrigerant, which enters the out-vehicle condenser 220. The refrigerant releases heat and liquefies in the out-vehicle condenser 220 to become a medium-temperature and high-pressure liquid. Subsequently, it enters the valve body cavity 203 through a pipeline connection to the second working fluid flow path 2022, and enters the electronic expansion valve 22 along the second flow path 2052 for throttling and expansion. The low-temperature and low-pressure gas-liquid mixture flowing through the electronic expansion valve 22 flows to the sixth working fluid flow path 2026 along the valve body cavity 203. The sixth working fluid flow path 2026 is connected to the battery upper cold plate 240 through a pipeline. The low-temperature and low-pressure gas-liquid mixture flows into the battery upper cold plate 240 along the pipeline after flowing out of the sixth working fluid flow path 2026. At this time, the low-temperature and low-pressure gas-liquid mixture absorbs the battery heat and evaporates, realizing the temperature reduction when the power battery temperature is too high. The refrigerant after cooling the power battery enters the valve body cavity 203 again through a pipeline connection to the fifth working fluid flow path 2025, enters the electronic expansion valve 21 along the first flow path 2051, and is connected to the first working fluid flow path 2021 through a pipeline, so that the refrigerant enters the gas-liquid separator 270 and the compressor 250 to perform the battery cooling cycle operation.

[0157] Mode 4: Battery heating mode

[0158] In the battery heating mode, refer to Figure 14, The high-temperature and high-pressure refrigerant flows out from the compressor 250, enters the valve body cavity 203 through the pipeline connecting to the first working medium flow path 2021, enters the electronic expansion valve 21 through the first flow path 2051 for throttling and expansion. The high-temperature and high-pressure gas-liquid mixture flowing through the electronic expansion valve 21 flows along the valve body cavity 203 to the fifth working medium flow path 2025. The fifth working medium flow path 2025 is connected to the battery upper cold plate 240 through the pipeline. At this time, the refrigerant condenses and releases heat to heat the battery, realizing battery heating, improving battery life, improving battery efficiency, improving battery capacity and vehicle endurance at low temperatures, and effectively shortening the charging time. The refrigerant after releasing heat is connected to the sixth working medium flow path 2026 through the pipeline, enters the electronic expansion valve 22 through the second flow path 2052 for throttling and expansion. The second working medium flow path 2022 is connected to the refrigerant inlet plate heat exchanger 260 through the pipeline.
