Description

Technical Field

[0001] This utility model belongs to the field of electronic control valve technology, and more specifically, relates to an electronic control valve for automotive refrigeration compressors. Background Technology

[0002] The electronically controlled valve of an automotive refrigeration compressor is a core component of the automotive air conditioning system. It is responsible for precisely regulating the flow path and flow rate of the refrigerant, thereby ensuring that the automotive air conditioning can provide appropriate cooling effects under different operating conditions. This electronically controlled valve is usually composed of a solenoid valve body, a solenoid coil, a control circuit, and sealing components. It controls the opening and closing of the valve through the action of electromagnetic force, thereby achieving effective management of refrigerant flow. With the continuous advancement of automotive electronics technology, the electronically controlled valve of modern automotive refrigeration compressors has become increasingly intelligent and precise.

[0003] In the construction of automotive refrigeration systems, the connection between the refrigeration compressor body and the electronic control valve body is a crucial link. Existing connection methods have certain limitations in terms of efficiency and convenience. Traditional connection methods usually rely on complex bolt tightening or welding techniques, which not only makes the installation and disassembly process time-consuming and labor-intensive, but also requires a lot of time and manpower to disassemble and reinstall when the electronic control valve needs to be repaired or replaced, which seriously affects maintenance efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an electronically controlled valve for automotive refrigeration compressors in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an electronically controlled valve for automotive refrigeration compressors, thereby addressing the issues of existing electronically controlled valves.

[0006] The purpose and function of this utility model's electronically controlled valve for automotive refrigeration compressors are achieved through the following specific technical means:

[0007] An electronically controlled valve for an automotive refrigeration compressor includes a refrigeration compressor body and an electronically controlled valve body. The upper top of the refrigeration compressor body has a limiting protrusion for installing the electronically controlled valve body. The electronically controlled valve body is installed at the position of the limiting protrusion. The outer wall of the limiting protrusion and the outer wall of the electronically controlled valve body are provided with quick-release mechanisms for rapid installation.

[0008] By adopting the above technical solution, the rapid connection and disassembly between the refrigeration compressor body and the electronic control valve body are realized, simplifying the process of installing and replacing the electronic control valve body. The operation can be easily completed without the use of complicated tools or cumbersome steps, reducing the overall operation process.

[0009] Furthermore, the quick-release mechanism includes a first mounting plate fixedly connected to the outer side wall of the main body of the electric control valve. A first arc-shaped locking block is symmetrically fixedly connected to the outer wall of the first mounting plate, and a first locking seat is symmetrically fixedly connected to the outer wall of the first mounting plate. The arc angle between the first arc-shaped locking block and the first locking seat is ninety degrees.

[0010] By adopting the above technical solution, the first arc-shaped card block and the second card seat, as well as the second arc-shaped card block and the first card seat, cooperate to form a stable and easy-to-operate connection structure.

[0011] Furthermore, the quick-release mechanism also includes a second mounting plate fixedly connected to the outer wall of the limiting protrusion. The outer wall of the second mounting plate is symmetrically fixedly connected with a second arc-shaped locking block and a second locking seat. The layout of the second mounting plate is the same as that of the first mounting plate. The outer walls of both sets of the first and second arc-shaped locking blocks are provided with toothed grooves.

[0012] By adopting the above technical solution, not only is the stability of the connection enhanced, but it also ensures that the main body of the electric control valve can be accurately installed on the limit protrusion.

[0013] Furthermore, both the first and second card holders have insertion slots on their outer walls. Magnetic toothed racks are inserted into the inner walls of both card holders within the insertion slots. A pull rod is fixedly connected to the center of the outer wall of the magnetic toothed rack. The magnetic toothed rack corresponds to the toothed grooves on the outer walls of the second and first arc-shaped card blocks.

[0014] By adopting the above technical solution, when the magnetic rack is inserted into the slot and meshes with the slot, a mechanical connection is formed between them, and the connection is strengthened by magnetic force. This not only ensures the stability of the electric valve body after installation, but also effectively prevents accidental detachment caused by vibration or external force.

[0015] Furthermore, a pressure ring is fixedly connected to the upper top of the second mounting plate, and the lower bottom of the first mounting plate is pressed against the upper top of the pressure ring.

[0016] By adopting the above technical solution, by pressing the bottom end of the first mounting plate onto the top end of the pressing ring, not only is the connection between the main body of the electronic control valve and the main body of the refrigeration compressor strengthened, but the connection is also effectively prevented from loosening due to vibration or external force.

[0017] Furthermore, the first arc-shaped card block is slidably connected inside the second card holder, and the second arc-shaped card block is slidably connected inside the first card holder.

[0018] By adopting the above technical solution, the stability of the connection is ensured, and the installation steps are greatly simplified.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This utility model incorporates a quick-release mechanism, which enables rapid connection between the refrigeration compressor body and the electronic control valve body during use. Furthermore, it allows for timely replacement of the electronic control valve body when damaged, saving time and improving efficiency. The quick-release mechanism is constructed with an upper and lower structure, consisting of a first mounting plate and a second mounting plate that cooperate to engage the first locking seat and the second arc-shaped locking block. The second locking seat engages the first arc-shaped locking block. Finally, a magnetic rack and pinion secure the second arc-shaped locking block and the magnetic rack on the outer wall of the first arc-shaped locking block, preventing detachment during use.

[0021] 2. In this utility model, when the main body of the electric control valve is damaged, the maintenance personnel can easily release the locking of the magnetic rack and tooth groove by simply moving the lever, so as to quickly disassemble and replace the main body of the electric control valve without a complicated disassembly process, thereby greatly saving maintenance time and improving work efficiency.

[0030] Example:

[0031] As attached Figure 1 To be continued Figure 3 As shown:

[0032] This utility model provides an electronically controlled valve for an automotive refrigeration compressor, including a refrigeration compressor body 1 and an electronically controlled valve body 2. The upper top of the refrigeration compressor body 1 has a limiting protrusion 4 for installing the electronically controlled valve body 2. The electronically controlled valve body 2 is installed at the position of the limiting protrusion 4. The outer wall of the limiting protrusion 4 and the outer wall of the electronically controlled valve body 2 are provided with a quick-release mechanism 3 for quick installation, which realizes quick connection and disassembly between the refrigeration compressor body 1 and the electronically controlled valve body 2, simplifies the process of installing and replacing the electronically controlled valve body 2, and can be easily completed without the use of complicated tools or cumbersome steps.

[0033] Please refer to Figure 1 and Figure 2The quick-release mechanism 3 includes a first mounting plate 31 fixedly connected to the outer wall of the electric control valve body 2. A first arc-shaped locking block 311 is symmetrically fixedly connected to the outer wall of the first mounting plate 31, and a first locking seat 312 is symmetrically fixedly connected to the outer wall of the first mounting plate 31. The arc angle between the first arc-shaped locking block 311 and the first locking seat 312 is ninety degrees. The quick-release mechanism 3 also includes a second mounting plate 32 fixedly connected to the outer wall of the limiting protrusion 4. A second arc-shaped locking block 322 is symmetrically fixedly connected to the outer wall of the second mounting plate 32. The second mounting plate 32 is connected to the second mounting base 321 and has the same layout as the first mounting plate 31. The outer walls of the two sets of first arc-shaped blocks 311 and second arc-shaped blocks 322 are provided with toothed grooves 34. Through the mutual cooperation of the first arc-shaped blocks 311 and the second mounting base 321, and the second arc-shaped blocks 322 and the first mounting base 312, a stable and easy-to-operate connection structure is formed. This not only enhances the stability of the connection, but also ensures that the electric control valve body 2 can be accurately installed on the limit protrusion 4, avoiding performance problems caused by installation deviation.

[0034] Please refer to Figure 3 Both the first card holder 312 and the second card holder 321 have insertion slots 37 on their outer walls. Magnetic racks 35 are inserted into the inner walls of both card holders 312 and 321 within the insertion slots 37. A pull rod 36 is fixedly connected to the center of the outer wall of the magnetic rack 35. The magnetic rack 35 corresponds to the toothed grooves 34 on the outer walls of the second arc-shaped card block 322 and the first arc-shaped card block 311. When the magnetic rack 35 is inserted into the insertion slot 37 and engages with the toothed groove 34, a mechanical connection is formed between them. The magnetic force also enhances the connection's firmness, ensuring the stability of the electric valve body 2 after installation and effectively preventing accidental detachment due to vibration or external force. When the electric valve body 2 needs to be disassembled, simply push the pull rod 36 to disengage the magnetic rack 35 from the toothed groove 34, thus achieving quick unlocking of the quick-release mechanism 3.

[0035] Please refer to Figure 2 and Figure 3 A pressure ring 33 is fixedly connected to the upper top of the second mounting plate 32, and the lower bottom of the first mounting plate 31 is pressed against the upper top of the pressure ring 33. By pressing the lower bottom of the first mounting plate 31 against the upper top of the pressure ring 33, not only is the connection between the electric control valve body 2 and the refrigeration compressor body 1 strengthened, but the connection is also effectively prevented from loosening due to vibration or external force. The first arc-shaped locking block 311 is slidably connected inside the second locking seat 321, and the second arc-shaped locking block 322 is slidably connected inside the first locking seat 312.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In this invention, the quick-release mechanism 3 is mainly composed of a first mounting plate 31 and a second mounting plate 32, which are respectively fixedly connected to the outer walls of the electric valve body 2 and the limiting protrusion 4. The first arc-shaped locking block 311 and the first locking seat 312 on the first mounting plate 31 cooperate with the second arc-shaped locking block 322 and the second locking seat 321 on the second mounting plate 32 to form a clever upper and lower structure locking mechanism. When it is necessary to install the electric valve body 2, simply slide the first arc-shaped locking block 311 into the second locking seat 321 and simultaneously slide the second arc-shaped locking block 322 into the first locking seat 312. This design not only ensures the stability of the connection but also greatly simplifies the installation steps. The magnetic rack 35 is inserted... The groove 37 is inserted into the first card holder 312 and the second card holder 321. The magnetic force and the meshing of the tooth groove further enhance the stability of the connection and effectively prevent the possible detachment during use. In addition, the design of the pressure ring 33 at the upper end of the second mounting plate 32 allows the lower end of the first mounting plate 31 to be tightly pressed onto the pressure ring 33, further improving the overall connection strength and sealing performance. When the main body 2 of the electric control valve is damaged, the maintenance personnel can easily release the locking of the magnetic rack 35 and the tooth groove 34 by simply moving the lever 36, realizing the quick disassembly and replacement of the main body 2 of the electric control valve without the need for a complicated disassembly process, thereby greatly saving maintenance time and improving work efficiency.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
