Description

Technical Field

[0001] This disclosure relates to the field of valve technology, and more particularly to an electronic expansion valve. Background Technology

[0002] In the design of electronic expansion valves, the valve body has a first flow channel for mounting valve components and a second flow channel for mounting sensors. The sensor element collects temperature or pressure information of the medium in the second flow channel, using this as control parameters for the control unit to provide feedback control to the actuator, thereby controlling the opening degree of the first flow channel. The electronic expansion valve also includes a circuit board that is electrically or signal-connected to the sensor.

[0050] Typical embodiments embodying the features and advantages of this disclosure will be described in detail in the following description. It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

[0051] In the following description of various exemplary embodiments of this disclosure, reference is made to the accompanying drawings, which form part of this disclosure, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this disclosure. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this disclosure. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this disclosure, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this disclosure.

[0052] See Figure 1 The illustration shows a three-dimensional schematic diagram of the electronic expansion valve proposed in this disclosure. In this exemplary embodiment, the electronic expansion valve proposed in this disclosure is described as an example of a thermal management system applied in applications such as vehicles. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other types of application scenarios, and these changes are still within the scope of the principle of the electronic expansion valve proposed in this disclosure.

[0053] like Figure 1 As shown, in one embodiment of this disclosure, the electronic expansion valve includes a valve body 100, an actuator 200, a valve component 230, a circuit board, a sensor element 300, and a connecting cable. (See also...) Figure 2 and Figure 3 , Figure 2 China representatively shows Figure 1 The front view; Figure 3 China representatively shows Figure 1 The diagram shows an exploded three-dimensional view, specifically separating the valve body 100, actuator 200, sensor element 300, and connecting cables. The following, in conjunction with the aforementioned figures, will provide a detailed description of the structure, connection method, and functional relationship of the main components of the electronic expansion valve proposed in this disclosure.

[0054] like Figures 1 to 3As shown, in one embodiment of this disclosure, the valve body 100 is provided with a first flow channel 101 and a second flow channel 102. An actuator 200 is connected to the valve body 100 and is provided with a first insertion interface 210. A portion of a valve component 230 extends into the first flow channel 101, and the actuator 200 is sleeved outside the other portion of the valve component 230. The actuator 200 drives the valve component 230 to move, thereby controlling the opening degree of the first flow channel 101. Specifically, by adjusting the movement position of the valve component 230, functions such as opening and closing the first flow channel 101 and flow regulation in the open-flow state can be achieved. A circuit board is located within the actuator 200. A sensor element 300 is connected to the valve body 100, and a portion of the sensor element 300 (including at least its probe portion) extends into the second flow channel 102. A connecting cable includes a first connecting end 410 and a second connecting end 420. The first connecting end 410 of the connecting cable is electrically or signal-connected to the first insertion interface 210 of the actuator 200 to achieve signal transmission and power supply. The second connecting end 420 of the connecting cable is electrically or signal-connected to the sensor element 300 (e.g., the portion extending beyond the valve body 100). Through this design, the present disclosure adopts a relatively independent, separate structure for the connecting cable and the actuator 200. Specifically, the first connecting end 410 of the connecting cable is connected and assembled with the first insertion interface 210 of the actuator 200. This allows the connecting cable to be suitable for applications where the sensor element 300 is far from the circuit board, thereby achieving a reliable and convenient connection between the sensor element 300 and the circuit board. Furthermore, the connecting cable structure used in this disclosure is simpler, improving connection reliability and reducing the assembly difficulty of the electronic expansion valve.

[0055] In one embodiment of this disclosure, the electronic expansion valve may further include a control unit. Specifically, the control unit is coupled to the actuator 200. "Coupled" means functionally capable of transmitting temperature information (or an electrical signal converted from temperature information) and transmitting control signals. The connection method can be wired or wireless. Based on this, the electronic expansion valve collects temperature information of the medium within the second flow channel 102 via the sensor element 300, so that the control unit can perform feedback control on the actuator 200 based on the temperature information.

[0056] like Figures 1 to 3As shown, in one embodiment of this disclosure, the first connecting end 410 of the connecting cable may be provided with a first plug structure, which is pluggably connected to the first insertion interface 210 of the actuator 200. Through the above design, this disclosure enables pluggable connection between the connecting cable and the first insertion interface, further reducing the assembly difficulty of the electronic expansion valve, and facilitating convenient disassembly during maintenance or replacement of related components. In other embodiments of this disclosure, while ensuring normal connection between the connecting cable and the actuator 200 and meeting connection requirements such as waterproofing, the first connecting end 410 and the first insertion interface 210 can be selected through various possible connection methods, such as, but not limited to, injection molding or post-welding sealing.

[0057] like Figure 2 As shown, in one embodiment of this disclosure, a first reinforcing rib 211 may be provided between the first connector 210 and the coil housing 220 of the actuator 200. Through the above design, this disclosure can further strengthen the structural strength of the first connector 210 and further improve the stability of the connection structure between the connecting cable and the actuator 200.

[0058] like Figures 1 to 3 As shown, in one embodiment of this disclosure, the sensor element 300 may be provided with a second connector. Furthermore, the second connection end 420 of the connecting cable may be provided with a second plug structure 421, which is pluggably connected to the second connector. Through the above design, this disclosure enables pluggable connection between the connecting cable and the sensor element 300, further reducing the assembly difficulty of the electronic expansion valve, and facilitating convenient disassembly during maintenance or replacement of related components. In other embodiments of this disclosure, while ensuring normal connection between the connecting cable and the sensor element 300 and meeting connection requirements such as waterproofing, the second connection end 420 may not be provided with a second plug structure 421. Various possible connection methods can be selected between the second connection end 420 and the second connector, such as, but not limited to, injection molding or post-welding sealing.

[0059] Based on the design of the sensor element 300 having a second connector, in an embodiment not shown in this disclosure, a second reinforcing rib may be provided between the second connector and the sensor element 300. Through this design, this disclosure can further strengthen the structural strength of the second connector and further improve the stability of the connection structure between the connecting cable and the sensor element 300.

[0060] like Figures 1 to 3As shown, based on the design of the first connecting end 410 and the second connecting end 420 of the connecting cable, a first plug structure and a second plug structure 421 are respectively provided. In one embodiment of this disclosure, the structures of the first connector 210 and the second connector can be the same, and the structures of the first plug structure and the second plug structure 421 can be the same. Accordingly, this disclosure enables the first plug structure and the second plug structure 421 to be interchangeably connected to the first connector 210 and the second connector, respectively. Through the above design, when connecting the connecting cable to the connectors of the actuator 200 and the sensor element 300, this disclosure does not require selecting the corresponding plug structure, that is, the plug structures provided on both connecting ends of the connecting cable can be plugged into the first connector 210 and the second connector hole, thereby further reducing the assembly difficulty of the electronic expansion valve.

[0061] like Figures 1 to 3 As shown, in one embodiment of this disclosure, a first flow channel 101 extends along a first direction (e.g., the X direction shown in the figures) and penetrates the valve body 100, a second flow channel 102 extends along the first direction and penetrates the valve body 100, and the first flow channel 101 and the second flow channel 102 are arranged at intervals along a second direction perpendicular to the first direction (e.g., the Y direction shown in the figures). A first connector 210, a sensor element 300, and a connecting cable are located on the same side of the valve body 100 in a third direction (e.g., the Z direction shown in the figures), which is perpendicular to both the first and second directions.

[0062] like Figures 1 to 3 As shown, in one embodiment of this disclosure, the connecting cable portion is bent towards the valve body 100 in a third direction to form a bend 430. For example, the connecting cable may include a metal core and an outer plastic sheath. Since the metal core has a certain degree of flexibility, the bend 430 can be formed by bending the connecting cable. Through the above design, on the one hand, considering that the distance between the first connector 210 of the actuator 200 and the sensor element 300 may change under conditions such as vibration or processing errors, this disclosure can use the bend 430 of the connecting cable to provide deformation buffering, compensate for the aforementioned distance change, and further improve the connection stability of the connecting cable between the sensor element 300 and the actuator 200. On the other hand, from an assembly perspective, this disclosure can use the bend 430 to allow for deformation during the assembly of the connecting cable with the first connector 210 or the sensor element 300, thereby further reducing the assembly difficulty. In addition, bending the bend 430 toward the valve body 100 avoids increasing the space occupied by the electronic expansion valve in the third direction, thus meeting the design requirements of miniaturization.

[0063] like Figures 1 to 3As shown, based on the design of the connecting cable having a bend 430, in one embodiment of this disclosure, the connecting cable can be fitted with a cable sheath 431, and the cable sheath 431 is located at least at the bend 430. Through this design, since the bend 430 is closer to the valve body 100 than other parts of the connecting cable, this disclosure can utilize the cable sheath 431 to protect the bend 430, preventing damage to the connecting cable when it is squeezed or bumped against the valve body 100 or other components, further ensuring the stability of the connection. Furthermore, the cable sheath 431 can also provide a certain degree of bending retention for the bend 430, preventing the connecting cable from springing back due to its own elasticity.

[0064] like Figures 1 to 3 As shown, in one embodiment of this disclosure, the sensor element 300 can be connected to the valve body 100 via a first connecting plate 310. Furthermore, the first connecting plate 310 is fixedly connected to the sensor element 300 (or can be an integral structure), and can be detachably connected to the valve body 100 via bolts, pins, rivets, or other means. Specifically, the first connecting plate 310 can adopt the structure shown in the accompanying drawings, for example, an approximately rhomboid structure. In some embodiments, the first connecting plate 310 can also adopt other structural forms, such as, but not limited to, a circular flange-like structure.

[0065] In one embodiment of this disclosure, the sensor element 300 may be a temperature sensor (e.g., a PT sensor), a pressure sensor, or a temperature-pressure sensor.

[0066] like Figures 1 to 3 As shown, in one embodiment of this disclosure, the actuator 200 may include a coil housing 220 and a drive component 240. The coil housing 220 is sleeved outside another part of the valve component 230 and connected to the valve body 100. The valve component 230 extends into the first flow channel 101 and is connected to the valve body 100. The valve component 230 includes a valve core. The drive component 240 is disposed within the coil housing 220 and is used to drive the valve core to move (e.g., move in a second direction) to control the opening degree of the first flow channel 101. A circuit board is disposed within the coil housing 220, and a pin for connecting to the circuit board is provided in the first insertion interface 210.

[0067] like Figures 1 to 3 As shown, in one embodiment of this disclosure, the actuator 200 may also be provided with a third connector 250, which is connected to the circuit board. The third connector 250 is used to connect an external power supply so that the external power supply can supply power to the sensor element 300 and the drive component 240.

[0068] like Figures 1 to 3As shown, based on the design of the actuator 200 having a third connector 250, in one embodiment of this disclosure, the opening of the first connector 210 and the opening of the third connector 250 can face different directions. For example, when the opening of the first connector 210 faces a second direction, the opening of the third connector 250 can face a first direction.

[0069] Based on the design of the actuator 200 with a third connector 250, in one embodiment of this disclosure, the control unit may include first control hardware, such as an electrical control cabinet or a vehicle control system. Furthermore, the third connector 250 can also be used to connect the first control hardware via a control cable. Accordingly, the third connector 250 can simultaneously connect the electronic expansion valve to both an external power supply and the control unit.

[0070] like Figure 2 As shown, based on the design of the actuator 200 with a third connector 250, in one embodiment of this disclosure, a third reinforcing rib 251 may be provided between the third connector 250 and the coil housing 220 of the actuator 200. Through the above design, this disclosure can further strengthen the structural strength of the third connector 250 and further improve the stability of the connection structure between the actuator 200 and the external power supply or the first control hardware.

[0071] like Figure 2 and Figure 3 As shown, in one embodiment of this disclosure, the actuator 200 may further include a second connecting plate 260, through which the actuator 200 is connected to the valve body 100. Furthermore, the second connecting plate 260 is fixedly connected to the coil housing 220 of the actuator 200 (or may be an integral structure), and is detachably connected to the valve body 100 via bolts, pins, rivets, or other means.

[0072] In one embodiment not illustrated in this disclosure, the control unit may include second control hardware, such as an electrical control cabinet or a vehicle control system. Furthermore, the actuator 200 may be equipped with a remote module, and the actuator 200 may be wirelessly coupled to the second control hardware via the remote module.

[0073] In one embodiment not illustrated in this disclosure, the control unit may include control software loaded on a mobile device, such as a mobile phone, tablet, or computer. Furthermore, the actuator 200 may be equipped with a remote module, and the actuator 200 may be wirelessly coupled to the mobile device via the remote module.

[0074] like Figure 1 and Figure 2As shown, in one embodiment of this disclosure, the sensor element 300 extends beyond the valve body 100, and all connecting cables are located outside the valve body 100. Through this design, this disclosure further reduces the assembly difficulty of the electronic expansion valve.

[0075] See Figure 4 and Figure 5 , Figure 4 A three-dimensional schematic diagram of an electronic expansion valve embodying the principles of this disclosure is shown in another exemplary embodiment. Figure 5 China representatively shows Figure 4 The three-dimensional exploded diagram shows the separation of the cover plate 120 from the body 110.

[0076] Different from Figures 1 to 3 The illustrated embodiment employs a design where all connecting cables are located outside the valve body 100, such as... Figure 4 and Figure 5 As shown, in one embodiment of this disclosure, the valve body 100 may include a body 110 and a cover. The body 110 is provided with a first flow channel 101 and a second flow channel 102, and the actuator 200 and the sensor element 300 are respectively connected to the body 110. The cover is connected to the valve body 100, and the cover and the valve body 100 together form a receiving cavity 103. The sensor element 300 partially extends out of the body 110 and is located within the receiving cavity 103, and the entire connecting cable is located within the receiving cavity 103. The end of the receiving cavity 103 facing the first insertion interface 210 is an open end. Through the above design, this disclosure arranges the portion of the sensor element 300 extending out of the body 110 and a portion of the connecting cable in the receiving cavity 103, thereby achieving protection for the sensor element 300 and the connecting cable, and further improving the reliability of the connection structure of the connecting cable.

[0077] like Figure 4 and Figure 5 As shown, in one embodiment of this disclosure, the body 110 may have a sidewall 111 on one side in the third direction. The sidewall 111 has an opening on the side away from the body 110 in the third direction, which can be closed by a cover plate 120. Accordingly, the sidewall 111 and the cover plate 120 together form the aforementioned cover and together with the body 110 form a receiving cavity 103. Furthermore, the sidewall 111 has another opening on the side near the actuator 200 in the second direction. This opening allows the first connecting end 410 of the connecting cable to extend out of the receiving cavity 103 and connect to the first plug-in interface 210. Through the above design, this disclosure allows the cover plate 120 to be assembled after the connecting cable is connected to the sensor element 300, thereby avoiding a significant impact on the assembly difficulty while utilizing the receiving cavity 103 to provide a containing and protective function.

[0078] like Figure 5As shown, based on the design of the valve body 100 having a receiving cavity 103, in one embodiment of this disclosure, the shape of a portion of the cavity wall of the receiving cavity 103 (e.g., a portion of the inner wall of the side wall 111) matches the shape of a portion of the outer wall of the sensor element 300 (e.g., the outer wall of the first connecting plate 310) so that a portion of the receiving cavity 103 forms a positioning groove 112 for positioning the portion of the sensor element 300 that extends out of the body 110.

[0079] It should be noted that the electronic expansion valves shown in the accompanying drawings and described in this specification are merely a few examples among many electronic expansion valves capable of employing the principles of this disclosure. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the electronic expansion valves shown in the accompanying drawings or described in this specification.

[0080] In summary, the electronic expansion valve proposed in this disclosure includes a valve body 100, an actuator 200, a valve component 230, a circuit board, a sensor element 300, and a connecting cable. The actuator 200 is provided with a first connector 210. The sensor element 300 is connected to the valve body 100 and partially extends into the second flow channel 102. The connecting cable includes a first connecting end 410 and a second connecting end 420. The first connecting end 410 is electrically or signal-connected to the first connector 210. The second connecting end 420 is electrically or signal-connected to the sensor element 300. Through the above design, this disclosure adopts a relatively independent split structure for the connecting cable and the actuator 200. Specifically, the first connecting end 410 of the connecting cable is connected and assembled with the first connector 210 of the actuator 200. This allows the connection structure of the connecting cable to be suitable for applications where the sensor element 300 is far from the circuit board, thereby achieving a reliable and convenient connection between the sensor element 300 and the circuit board. In addition, the connecting cable used in this disclosure is simpler, improving connection reliability and reducing the assembly difficulty of the electronic expansion valve.
