[0002] The electronically controlled valve in an automotive air conditioning system is one of the core components for achieving precise temperature control. The electronically controlled valve typically includes a valve body and a valve cap located on one side of the valve body. The valve cap contains a precision electromagnetic coil or control unit.

[0003] The valve caps of existing electronically controlled valves are mostly simple plastic or metal thin-shell structures with low mechanical strength and lack of effective protection. Once subjected to external impact, the valve caps are very easy to break or deform, which in turn causes the internal electrical components to become damp, short-circuit or be damaged. To address this problem, the inventors designed an electronically controlled valve for automotive refrigeration and air conditioning equipment. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0019] Please see Figures 1 to 4 One embodiment of this utility model is an electrically controlled valve for automotive refrigeration and air conditioning equipment. The electrically controlled valve includes an electrically controlled valve body 1 and a protective component 2, with the protective component 2 located on one side of the electrically controlled valve body 1. The main body 1 of the electrically controlled valve includes a frame 11 and a valve cap 12, with the valve cap 12 located on one side of the frame 11; The protective component 2 includes an inner tube 21, a connecting rib 22, an outer tube 23, and a connecting plate 24. The inner tube 21 is located outside the valve cap 12. The connecting rib 22 is fixed to the outer wall of the inner tube 21, and the connecting rib 22 is arranged in a circular array outside the inner tube 21 with the center of the inner tube 21 as a reference point. The outer tube 23 is fixed to the outer surface of the connecting rib 22. The connecting plate 24 is fixed to the outer surface of the inner tube 21 and the outer tube 23 on the side away from the frame 11, and the surface of the connecting plate 24 is in contact with the surface of the valve cap 12.

[0020] The connecting plate 24 has a connecting groove 25 inside, and the connecting groove 25 is distributed in a circular array inside the connecting plate 24 with the center of the connecting plate 24 as a reference point.

[0021] The skeleton 11 serves as the structural foundation of the electrically controlled valve, used for mounting and supporting all other components. The valve cap 12 is the most vulnerable part of the electrically controlled valve, and a precision electromagnetic coil is encapsulated inside it. The inner tube 21 serves as the first line of defense and inner support for the protection member 2. The outer tube 23 is the outermost layer of the protection member 2, and is the main component for resisting external impacts and bumps. The connecting ribs 22 connect the inner tube 21 and the outer tube 23, so that a certain gap is maintained between the two. When the outer tube 23 is impacted, the impact force can be transmitted through the connecting ribs 22, and the circumferential array design enables the impact force to be uniformly dispersed to the entire inner tube 21 instead of being concentrated on one point, thereby preventing the valve cap 12 from cracking due to point impact.

[0022] A connecting hole 26 is opened in the middle of the connecting plate 24, and the cross-sectional profile of the connecting hole 26 is convex-shaped.

[0023] The connecting hole 26 allows the screw 27 to be completely sunk into the hole without protruding from the surface of the connecting plate 24.

[0024] The connecting plate 24 and the inner part of the valve cap 12 are threadedly connected with the screw 27, and the screw 27 is located inside the connecting hole 26.

[0025] The screw 27 firmly fixes the entire protection member 2 onto the valve cap 12, and the disassembly and assembly thereof is the key to realizing the quick replacement function.

[0026] A protection tube 28 is inserted inside the inner tube 21 and the outer tube 23.

[0027] The protection tube 28 is inserted between the inner tube 21 and the outer tube 23, and is used for sealing the openings at both ends. It can effectively prevent water vapor, dust and pollutants from entering the cavity between the inner tube 21 and the outer tube 23, and avoid the influence of corrosion on the strength and stability of the internal connecting ribs 22.

[0028] A fixing block 29 is fixed on the surface of the outer tube 23, the surface of the fixing block 29 fits the surface of the protection tube 28, and the fixing block 29 provides a support with a hole.

[0029] A tapered post 291 is fixed on the surface of the protection tube 28, and the tapered post 291 is inserted inside the fixing block 29. By means of the tapered structure, the tapered post 291 can be conveniently inserted and aligned with the hole on the fixing block 29 to achieve tight fit.

[0030] Working principle: When the protective part 2 outside the valve cap 12 is damaged, a rotational force is applied to the screw 27 to remove the screw 27 from inside the connecting plate 24. Then, a pulling force is applied to the outer tube 23 to remove the inner tube 21 from outside the valve cap 12. A new inner tube 21 is then inserted into the outside of the valve cap 12. Subsequently, the screw 27 is turned into the connecting plate 24 and the inside of the valve cap 12, and the screw 27 is stored inside the connecting hole 26. This increases the stability of the valve cap 12 structure. Furthermore, the protective tube 28 prevents moisture from entering between the inner tube 21 and the outer tube 23, thus avoiding affecting the stability of the structure.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
