Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and more specifically, to the inductor sheath of a vehicle scroll compressor controller. Background Technology

[0002] Due to the application scenarios of electric scroll compressors, their external space is limited by the overall vehicle installation space, which in turn restricts the layout of the controller. Some large electronic components, such as large capacitors and large inductors, often require special adjustments or matching. The complex controller cavity design not only increases manufacturing difficulty and cost, but also affects electrical insulation and other characteristics.

[0003] Existing controllers often have inductive fixing components that lack sufficient strength and functionality. For example, patent number CN204178929U provides a compressor capacitor fixing clip and a compressor capacitor fixing structure using this clip. The compressor capacitor fixing clip provided by this invention includes a cylindrical body made of plastic. At least one buckle extends from one end edge of the cylindrical body to restrict the vertical movement of the capacitor. A locking structure is provided on the outside of the cylindrical body to assemble and fix the clip onto the compressor control box. However, the intention of this structure is to increase assembly efficiency and reduce the difficulty of replacement due to bolt corrosion by eliminating bolts, thus achieving quick and convenient replacement of parts. It does not inherently require high fixing strength.

[0004] Therefore, this utility model provides an inductor sheath for an automotive scroll compressor controller. Summary of the Invention

Figure 2 This is an assembly diagram of the inductor sheath and plug-in of the automotive scroll compressor controller of this utility model. Figure 3 This is an assembly diagram of the inductor sheath and controller cavity of the automotive scroll compressor controller of this utility model. Figures 1 to 3 As shown, the inductor sheath of the automotive scroll compressor controller of this utility model includes: an inductor insulating sheath body 1 and a limiting ear plate 14. The inductor insulating sheath body 1 includes: a semi-circular groove 11, two screw-connected ear plates 12, and a limiting ear plate 14. The semi-circular groove 11 forms a semi-circular cavity to accommodate the inductor coil 4. The two screw-connected ear plates 12 are respectively connected to the two ends of the semi-circular groove 11, and each screw-connected ear plate 12 is provided with a screw hole 13. The limiting ear plate 14 is connected to one side of the semi-circular groove 11, and the limiting ear plate 14 is provided with a wire passage hole 15 for limiting the wire harness. When the semi-circular groove 11 is screwed into the controller cavity 2, the inductor coil 4 is connected in the semi-circular groove 11, and the limiting ear plate 14 is located at the port of the plug-in 5. The high-voltage plug-in wire harness 6 extending from the plug-in 5 passes through the wire passage hole 15 and is limited.

[0046] In a preferred embodiment, the limiting ear plate 14 is integrally formed with the semi-circular groove 11, and the semi-circular groove 11 is integrally formed with the screw-in ear plate 12, but this is not a limitation.

[0048] In a preferred embodiment, the screw lug 12 is a thin plate extending outward from both ends of the semicircular groove 11, but is not limited thereto.

[0049] In a preferred embodiment, the bottom of the controller cavity 2 is filled with adhesive to bond the inductor insulating sheath body 1, but this is not a limitation.

[0050] In a preferred embodiment, the area of ​​the fixing adhesive is greater than 50% of the area of ​​the inductor insulating sheath body 1, but is not limited thereto.

[0051] In a preferred embodiment, the interior of the semi-circular groove 11 is filled with adhesive to bond the inductor coil 4, but this is not a limitation.

[0052] In a preferred embodiment, the liquid level of the fixing adhesive is greater than 50% of the depth of the semi-circular groove 11, but is not limited thereto.

[0053] The specific implementation of this utility model is as follows: (Refer to...) Figures 1 to 3 In this invention, the semi-circular groove 11 of the inductor sheath of the automotive scroll compressor controller forms a semi-circular cavity to accommodate the inductor coil 4. Two screw-on lugs 12 are respectively connected to both ends of the semi-circular groove 11, and each screw-on lug 12 is provided with a screw hole 13. A limiting lug 14 is connected to one side of the semi-circular groove 11, and the limiting lug 14 is provided with a wire passage hole 15 for limiting the wire harness. When the semi-circular groove 11 is screwed into the controller cavity 2, the inductor coil 4 is connected inside the semi-circular groove 11, and the limiting lug 14 is located at the port of the plug 5. The high-voltage plug wire harness 6 extending from the plug 5 passes through the wire passage hole 15 and is limited. The limiting lug 14 is integrally formed with the semi-circular groove 11, and the semi-circular groove 11 is integrally formed with the screw-on lug 12. The limiting lug 14 is a cuboid, and the limiting lug 14 is provided with at least two wire passage holes 15. The extension direction of the wire passage holes 15 is perpendicular to the opening plane of the semi-circular groove 11. The screw-in lug 12 is a thin plate extending outward from both ends of the semi-circular groove 11. The bottom of the controller cavity 2 is filled with adhesive to bond the inductor insulating sheath body 1. The area of ​​the adhesive is greater than 50% of the area of ​​the inductor insulating sheath body 1. The interior of the semi-circular groove 11 is filled with adhesive to bond the inductor coil 4. The level of the adhesive is greater than 50% of the depth of the semi-circular groove 11.

[0054] In this invention, the inductor sheath is used in conjunction with the controller cavity 2 using bolts 3 and fixing adhesive. This combination satisfies the functions of fixing the inductor coil 4, strengthening the insulation of the device, and guiding and limiting the installation of the plug-in 5. The detachable inductor sheath allows for structural and functional optimization without affecting the main structure of the controller cavity 2. This invention solves the problem of insufficient constraint on the large inductor coil 4, which cannot guarantee stability, without changing the main structure of the controller cavity 2. Simultaneously, the extended inductor sheath structure assists in positioning the high-voltage plug-in wiring harness 6. This not only reduces the processing steps of the controller cavity but also strengthens the insulation distance between the inductor and the housing. Compared with the prior art CN204178929U, this invention strengthens the fixation and improves the stability of the large inductor coil 4 without changing the controller cavity 2. Although both serve the functions of fixing devices and installation, their actual focuses are different.

[0055] In this invention, the overall structure of the controller cavity 2 remains unchanged, but an installation point and limiting structure for fixing the inductor protective sleeve are added. The inductor sleeve can be installed using M3 bolts 3 and by applying a fixing adhesive covering more than half the area of ​​the sleeve base at the limiting point of the controller cavity 2. Furthermore, the high-voltage connector harness 6 is limited by passing it through the wire hole 15 of the limiting ear plate 14. During controller installation, the inductor coil 4 is positioned inside the controller cavity 2, and the high-voltage connector harness 6 is positioned at the controller installation point. Applying a fixing adhesive covering more than half the height of the inductor inside the controller cavity 2 further enhances the fixing effect for the large inductor.

[0056] Large electronic components on controllers often require different dispensing processes and structural designs for fixation and support, or they may need to be arranged horizontally. This not only affects the production schedule but also increases the difficulty of controller board layout. The inductor sleeve assembly installation mode of this invention ensures that the overall structure of the controller cavity 2 remains unchanged, the processing technology is not complicated, and the need to adjust the inductor angle avoids insufficient space for controller board layout. It also avoids complex dispensing processes; the desired effect can be achieved simply by dispensing adhesive inside the sleeve. Simultaneously, the limiting ear plate 14 limits the high-voltage plug-in wiring harness 6, reducing the positioning difficulty of the control board during installation.

[0057] In summary, the purpose of this utility model is to provide an inductor sheath for an automotive scroll compressor controller, which can reduce the assembly difficulty of the controller and its housing and improve the stability of related components without increasing the housing processing technology.

[0058] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
