Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In existing technology, electronic expansion valves include a valve body, a coil component, and a rotor component. The coil component, when energized, generates a magnetic field that drives the rotor component to rotate, thereby moving the valve core component within the valve body and adjusting the valve opening. The coil component is fixed to the valve body via a snap-fit ​​assembly using a fixing structure. This fixing structure is installed onto the coil component after injection molding, then laser-welded for positioning, and finally encapsulated with epoxy resin to ensure the positioning strength of the fixing structure. This process is complex and inefficient.

[0032] In view of this, the present invention proposes an electronic expansion valve 100.

[0033] Please see Figures 1 to 3 In one embodiment of this utility model, the electronic expansion valve 100 includes a valve body 1 and a coil assembly 200. A mounting bracket 2 is installed on the outer wall of the valve body 1. The coil assembly 200 is sleeved on the valve body 1. The coil assembly 200 includes a stator component 3, a plastic sealing part 4, and a fixing structure 5. The plastic sealing part 4 covers the stator component 3. The plastic sealing part 4 has a slot 41. A limiting protrusion 411 protrudes from the inner wall of the slot 41. The fixing structure 5 includes a plug-in part 51 and a mounting part 52 connected to each other. The plug-in part 51 is inserted into the slot 41 and engaged with the limiting protrusion 411. The mounting part 52 is mounted on the mounting bracket 2.

[0034] It should be noted that the electronic expansion valve 100 is commonly used in refrigeration equipment and systems, mainly in air conditioners, to regulate the flow of refrigerant entering the refrigeration equipment.

[0035] The valve body 1 and the mounting bracket 2 can be either fixedly connected or detachably connected. In this embodiment, the valve body 1 and the mounting bracket 2 are fixedly connected by a fixing structure 5. When the connection between the fixing structure 5 and the mounting bracket 2 is released, the mounting bracket 2 can be removed from the valve body 1.

[0036] As mentioned above, the installation of the fixing structure 5 typically requires laser welding to position it on the stator component 3, followed by secondary injection molding and encapsulation 4 to form a single unit. However, in this embodiment, to save installation steps, a slot 41 is provided on the encapsulation 4, and the fixing structure 5 includes a plug-in part 51. The fixing structure 5 is installed on the encapsulation 4 through the mating of the plug-in part 51 and the slot 41, thus eliminating the need for welding and secondary injection molding. The encapsulation 4 is integrally formed, saving on processing technology. Furthermore, to ensure a more secure fit between the plug-in part 51 and the slot 41, a limiting protrusion 411 is provided within the slot 41. The limiting protrusion 411 secures the plug-in part 51 within the slot 41, thereby ensuring the strength of the fit between the fixing structure 5 and the encapsulation 4.

[0037] The slot 41 can be designed with different shapes and sizes to accommodate different insertion portions 51. The limiting protrusion 411 can be designed with different tilt angles and heights to provide different locking forces and stability. The insertion portion 51 can be designed with different thicknesses and shapes to accommodate different slots 41 and limiting protrusions 411. The mounting portion 52 can be designed with different protrusion heights and shapes to accommodate different mounting brackets 2 and mounting holes 221.

[0038] The technical solution of this utility model simplifies the connection between the coil assembly 200 and the valve body 1 by incorporating a slot 41 on the encapsulation part 4 and engaging the slot 41 with the fixing structure 5. Specifically, the slot 41 and the limiting protrusion 411 on the encapsulation part 4 engage with the insertion part 51 of the fixing structure 5, allowing the coil assembly 200 to be quickly and securely fixed to the valve body 1. This design not only reduces installation steps but also improves installation accuracy and reliability. Furthermore, the cooperation between the mounting part 52 and the mounting bracket 2 further enhances the overall structural stability. Through this structural design, this application effectively solves the problems of complex and inefficient installation processes of the fixing structure 5 in traditional electronic expansion valves 100.

[0039] In one embodiment, please refer to Figure 3 and Figure 4The slot 41 includes a first sidewall 41a and a second sidewall 41b disposed opposite to each other. The limiting protrusion 411 protrudes from the first sidewall 41a. The insertion part 51 is provided with a locking hole 511, and the locking hole 511 and the limiting protrusion 411 are engaged in a locking fit.

[0040] Specifically, the first sidewall 41a and the second sidewall 41b of the slot 41 are arranged opposite to each other, and the limiting protrusion 411 protrudes from the first sidewall 41a. The insertion part 51 has a locking hole 511, which engages with the limiting protrusion 411. With this design, when the insertion part 51 is inserted into the slot 41, the locking hole 511 and the limiting protrusion 411 form a locking engagement, which enhances the connection stability between the insertion part 51 and the slot 41 and solves the technical problem of unstable locking engagement between the slot 41 and the insertion part 51.

[0041] Therefore, this application solves the technical problem of unstable engagement between the slot 41 and the plug-in part 51 by having the first sidewall 41a and the second sidewall 41b of the slot 41 arranged opposite to each other, with the limiting protrusion 411 protruding from the first sidewall 41a, and the plug-in part 51 having a locking hole 511 that engages with the limiting protrusion 411. Compared with the prior art, the technical solution of this application simplifies the installation process, improves installation efficiency, and enhances the connection stability between the plug-in part 51 and the slot 41.

[0042] In one embodiment, please continue to refer to Figure 4 The limiting protrusion 411 is arranged in the form of an inclined platform. The limiting protrusion 411 includes a guide surface 411a and a limiting surface 411b. The guide surface 411a extends along the insertion direction of the insertion part 51 and is inclined from the first side wall 41a toward the other second side wall 41b. The limiting surface 411b limits the insertion part 51.

[0043] Specifically, the inclined design of the guide surface 411a allows the insertion part 51 to slide smoothly into the slot 41, reducing the possibility of jamming. The limiting surface 411b is used to limit the insertion part 51 after it is inserted into the slot, ensuring a stable engagement between the insertion part 51 and the limiting protrusion 411. In a preferred embodiment, the angle between the guide surface 411a and the first sidewall 41a is A, and the angle between the limiting surface 411b and the first sidewall 41a is B, where 0° < A < B ≤ 90°. This angle setting further optimizes the insertion and limiting effect of the insertion part 51.

[0044] Therefore, through the cooperation of the guide surface 411a and the limiting surface 411b, the plug-in part 51 can be inserted into the slot 41 more smoothly and remain stable after being inserted into place, solving the technical problem that the plug-in part 51 is prone to jamming or difficult to insert into the slot 41. Compared with the prior art, this technical solution simplifies the installation process, improves installation efficiency, and enhances the stability of the snap-fit ​​cooperation between the plug-in part 51 and the limiting protrusion 411.

[0045] In one embodiment, please continue to refer to Figure 4 The angle between the guide surface 411a and the first sidewall 41a is A, the angle between the limiting surface 411b and the first sidewall 41a is B, and 0° < A < B ≤ 90°.

[0046] Furthermore, this application proposes that the angle between the guide surface 411a and the first sidewall 41a is A, and the angle between the limiting surface 411b and the first sidewall 41a is B, where 0° < A < B ≤ 90°. Specifically, the angle A between the guide surface 411a and the first sidewall 41a is designed to be smaller than the angle B between the limiting surface 411b and the first sidewall 41a, and both A and B are greater than 0° and do not exceed 90°. This design allows the guide surface 411a to provide a gradually tilting guide effect when the insertion part 51 is inserted into the slot 41, helping the insertion part 51 smoothly enter the slot 41, while the limiting surface 411b provides a larger angle to ensure that the insertion part 51 is stably limited after reaching the predetermined position, preventing it from dislodging or loosening. This angle design ensures both smooth assembly and improved stability after assembly.

[0047] Specifically, the angle A between the guide surface 411a and the first sidewall 41a can be designed to be any angle between 15° and 45°, while the angle B between the limiting surface 411b and the first sidewall 41a can be designed to be any angle between 60° and 90°. As a preferred embodiment, A can be designed to be 30° and B can be designed to be 75°. This angle design not only ensures that the insertion part 51 is smoothly guided during insertion, but also provides sufficient limiting force after the insertion part 51 reaches the predetermined position to prevent it from loosening or dislodging.

[0048] Therefore, the technical solution of this application solves the problems of poor guidance and unstable positioning that the insertion part 51 may encounter when inserted into the slot 41 by reasonably designing the included angle between the guide surface 411a and the limiting surface 411b and the first side wall 41a. Compared with the prior art, the technical solution of this application not only simplifies the assembly process, but also improves the stability and reliability after assembly, avoiding assembly difficulties or positioning failures caused by improper angle design.

[0049] In one embodiment, please refer to Figure 3 and Figure 4 The minimum distance between the limiting protrusion 411 and the second sidewall 41b is D, and the thickness of the insertion part 51 is T, where T > D.

[0050] Specifically, the minimum distance D between the limiting protrusion 411 and the second sidewall 41b refers to the minimum gap between the limiting protrusion 411 and the second sidewall 41b of the slot 41, while the thickness T of the insertion part 51 refers to the actual thickness of the insertion part 51 when inserted into the slot 41. By limiting T to be greater than D, it is ensured that the insertion part 51 fits tightly with the limiting protrusion 411 after being inserted into the slot 41, avoiding loosening or falling off due to size mismatch. This design enhances the fit stability between the insertion part 51 and the slot 41 by precisely controlling the dimensional relationship between them, thereby improving the overall reliability and service life of the electronic expansion valve 100.

[0051] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 6 The mounting portion 52 protrudes towards the encapsulated portion 4 to form a raised portion 521, and the mounting bracket 2 has a mounting hole 221, and the raised portion 521 is engaged with the mounting hole 221.

[0052] The design of the raised portion 521 allows the mounting portion 52 to directly engage with the mounting hole 221, avoiding the complex installation process of the traditional fixing structure 5 and thus improving installation efficiency. Furthermore, the snap-fit ​​design ensures a more secure connection between the mounting portion 52 and the mounting bracket 2, reducing the risk of loosening or detachment. Specifically, the raised portion 521 can be formed by injection molding or machining, and its shape can be circular, square, or other shapes suitable for snap-fit. The shape and size of the mounting hole 221 should match the raised portion 521 to ensure a tight and stable snap-fit ​​engagement.

[0053] Therefore, this technical solution effectively solves the technical problems of weak connection and low installation efficiency between the mounting part 52 and the mounting bracket 2 by simplifying the installation process and improving connection strength. Compared with the prior art, this solution not only reduces installation steps and process complexity, but also improves installation reliability and efficiency, demonstrating significant practicality and innovation.

[0054] In one embodiment, please refer to Figure 6 and Figure 7 The mounting bracket 2 includes a sleeve portion 21 sleeved on the valve body 1 and a mounting plate 22 for abutting against the plastic seal portion 4, and the mounting hole 221 is formed in the mounting plate 22.

[0055] Furthermore, this application proposes that the mounting bracket 2 includes a sleeve portion 21 fitted onto the valve body 1 and a mounting plate 22 for abutting against the plastic seal portion 4, with a mounting hole 221 formed in the mounting plate 22. The sleeve portion 21 is directly fitted onto the valve body 1, ensuring a secure connection between the mounting bracket 2 and the valve body 1, while the mounting plate 22, by abutting against the plastic seal portion 4, further enhances the structural stability. The design of the mounting hole 221 allows the mounting plate 22 to be fixed to the plastic seal portion 4 via a simple snap-fit ​​or bolt connection, thereby simplifying the installation process.

[0056] Specifically, the sleeve can fit tightly onto the valve body 1 to prevent loosening. The mounting plate 22 can be designed with multiple mounting holes 221 to accommodate plastic seals 4 of different sizes or shapes. In addition, the surface of the mounting plate 22 can be provided with anti-slip texture or coating to increase the friction between it and the plastic seal 4, further improving the stability of the connection.

[0057] Therefore, the technical solution of this application simplifies the connection structure between the mounting bracket 2 and the plastic seal 4 by designing the mounting bracket 2 as consisting of a sleeve part 21 and a mounting plate 22, avoiding the complex installation and welding process of the fixing structure 5, thereby improving installation efficiency. The direct fitting of the sleeve part 21 to the valve body 1 ensures the stability of the mounting bracket 2, while the abutment between the mounting plate 22 and the plastic seal 4 further enhances the structural stability. Compared with the prior art, the technical solution of this application not only simplifies the installation process but also improves the reliability and efficiency of installation.

[0058] In one embodiment, please refer to Figure 1 and Figure 3 The encapsulated part 4 is provided with a wire component 42, which extends toward the side away from the stator component 3. The wire component 42 and the fixing structure 5 are respectively located on opposite sides of the stator component 3.

[0059] Specifically, the wire guide component 42 is used to accommodate the external wire 6 of the electronic expansion valve 100. The wire guide component 42 is positioned so that the wire 6 can be led out from one side of the stator component 3, avoiding interference between the wire 6 and the fixed structure 5. The wire guide component 42 extends away from the stator component 3, further optimizing the spatial layout. This ensures that the lead-out direction of the wire guide component 42 is opposite to the installation direction of the fixed structure 5, facilitating the manufacturer's operation of electrical connections between other components of the refrigeration equipment and the electronic expansion valve 100. The insertion port 412 of the slot 41 and the opening 421 of the wire guide component 42 face opposite directions, ensuring that the lead-out direction of the wire guide component 42 is opposite to the installation direction of the fixed structure 5, further simplifying the installation process.

[0060] Therefore, by placing the conductor component 42 and the fixing structure 5 on opposite sides of the stator component 3, the layout of the conductor component 42 and the installation of the fixing structure 5 do not interfere with each other, simplifying the installation process. The conductor component 42 extends towards the side opposite to the stator component 3, further optimizing the spatial layout and avoiding conflict between the conductor component 42 and the fixing structure 5. The insertion port 412 of the slot 41 and the opening 421 of the conductor component 42 face opposite directions, ensuring that the lead-out direction of the conductor component 42 is opposite to the installation direction of the fixing structure 5, reducing installation complexity and improving installation efficiency. Compared with the prior art, the technical solution of this application significantly simplifies the installation process, improves installation efficiency, and solves the problems of complex and inefficient installation of the fixing structure 5 in the prior art.

[0061] In one embodiment, please continue to refer to Figure 1 and Figure 3 The slot 41 has a socket 412, which faces away from the orientation of the opening 421 of the wire component 42.

[0062] Specifically, the insertion port 412 of the slot 41 faces opposite directions to the opening 421 of the wire component 42, avoiding spatial conflict between the slot 41 and the wire component 42. This allows the insertion part 51 to be smoothly inserted into the slot 41, while the wire component 42 can extend normally, resolving the issue of conflicting orientations between the slot 41 and the opening 421 of the wire component 42. Through this design, the slot 41 and the wire component 42 do not interfere with each other spatially, ensuring the assembly efficiency and structural stability of the electronic expansion valve 100. Secondly, it makes the assembly of the electronic expansion valve 100 more convenient.

[0063] Therefore, the technical solution of this application effectively solves the spatial conflict problem between the slot 41 and the wire component 42 by opposing the orientation of the insertion port 412 of the slot 41 and the opening 421 of the wire component 42. This design not only improves the assembly efficiency of the electronic expansion valve 100, but also enhances the stability of the structure. Compared with the prior art, the technical solution of this application simplifies the assembly process, reduces misoperation during assembly, and improves the accuracy and efficiency of assembly.

[0064] This utility model also proposes a refrigeration device, which includes an electronic expansion valve 100. The specific structure of the electronic expansion valve 100 is as described in the above embodiments. Since this refrigeration device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
