[0076]

[0077] Hereinafter, various embodiments disclosed in this specification will be described in detail with reference to the attached drawings. Identical or similar components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0078]

[0079] Referring to FIGS. 1 to 6, an embodiment of the electric compressor of the present invention comprises: a main body (1); a controller (3) coupled to the main body (1); a protruding part (5) provided on the controller (3) and protruding toward the main body (1); a receiving part (7) formed on the main body (1) to be inserted and wrapped around the protruding part (5); and a protective cap (9) that is placed over the protruding part (5) and inserted into the receiving part (7).

[0080] That is, the electric compressor of the present invention is configured by combining the main body (1) and the controller (3), wherein the controller (3) is provided with a protruding part (5) protruding toward the main body (1), and the main body (1) has a receiving part (7) into which the protruding part (5) is inserted, and the protruding part (5) is inserted into the receiving part (7) of the main body (1) with the protective cap (9) covering it to be assembled.

[0081] Accordingly, the main body (1) and the controller (3) form a very tight coupling structure, allowing the electric compressor to be configured very compactly. The protruding part (5) of the controller (3), which is inserted and assembled into the receiving part (7) of the main body (1), is covered and cushioned by the receiving part (7) of the main body (1) and the protective cap (9) against various vibrations or shocks input toward the protruding part (5), thereby improving robustness against fatigue failure and ultimately improving the durability of the electric compressor.

[0082] In addition, the outer surface of the protective cap (9) is provided with a cushioning rib (11) that forms a cushioning space between it and the receiving portion (7) of the main body (1), thereby maximizing the insulation effect against vibrations and shocks input to the protruding part (5).

[0083]

[0084] The main body (1) and the controller (3) each have a basic coupling surface (13) that is joined by surface contact with each other; and the protruding part (5) protrudes toward the main body (1) so as to pass through the basic coupling surface (13).

[0085] That is, the connection between the main body (1) and the controller (3) is mainly formed by the area where the basic connection surfaces (13) come into surface contact with each other, and the protruding part (5) is in a state of protrusion so as to pass through the basic connection surfaces (13) and be inserted into the main body (1).

[0086] Here, the protruding part (5) may be a capacitor, etc., of an inverter constituting the controller (3), and the main body (1) may be a housing, etc., containing a motor and scroll, etc. of an electric compressor.

[0087]

[0088] The protective cap (9) is formed in a bowl shape that wraps around the end and circumference of the protruding part (5).

[0089] Accordingly, when assembling the main body (1) and the controller (3), the protective cap (9) is placed on the end of the protruding part (5) of the controller (3), and then inserted into the receiving part (7) of the main body (1) to assemble them.

[0090] The protruding part (5) and the protective cap (9) can be joined by an adhesive (15).

[0091] In this way, when the protruding part (5) and the protective cap (9) are joined together by an adhesive (15) and the protective cap (9) are inserted into the receiving part (7) of the main body (1), if the controller (3) needs to be replaced later, when the controller (3) is separated from the main body (1), the protective cap (9) is detached from the receiving part (7) along with the controller (3), thereby eliminating the need for additional work to remove the protective cap (9) from the receiving part (7).

[0092] Therefore, since the controller (3) and the main body (1) can be easily disassembled, maintenance becomes easier.

[0093]

[0094] The above protective cap (9) may be provided with a skirt portion (17) having an opening cross-sectional area that is enlarged at the entrance portion into which the above protruding part (5) is inserted.

[0095] The skirt portion (17) described above can perform the function of aligning and guiding the assembly position when the protruding part (5) covered with the protective cap (9) is inserted into the receiving portion (7) of the main body (1).

[0096] Additionally, as illustrated in FIG. 6, the receiving portion (7) of the main body (1) may have the shape of a tapered groove in which the opening cross-sectional area is gradually expanded toward the basic coupling surface (13).

[0097] Accordingly, when the protruding part (5) covered with the protective cap (9) is inserted into the receiving part (7), it provides easier assembly, and when the controller (3) is replaced, it can provide easy separation of the protective cap (9) from the receiving part (7).

[0098]

[0099] Referring to FIGS. 7 and FIGS. 8, the protective cap (9) may be integrally provided with a separating band (19) extending toward the opening direction of the protective cap (9) at the inlet portion into which the protruding part (5) is inserted.

[0100] Additionally, a band groove (21) for receiving the end of the separation band (19) of the protective cap (9) may be formed on the basic coupling surface (13) of the main body (1).

[0101] For reference, the opening direction of the protective cap (9) can be understood as a direction perpendicular to the surface formed by the entrance of the protective cap (9), and opposite to the direction in which the protruding part (5) is inserted.

[0102] When using a protective cap (9) with the configuration described above, it is possible to easily disassemble and assemble the controller (3) when replacing it without joining the protruding part (5) and the protective cap (9) with an adhesive (15).

[0103] That is, when the protective cap (9) equipped with the separation band (19) as described above is placed over the protruding part (5) and inserted into the receiving part of the main body (1) to achieve the assembly state as shown in FIG. 7, the end of the separation band (19) can be inserted into the band groove (21), so that when separating the controller (3) thereafter, even if the protective cap (9) remains in the receiving part (7), the protective cap (9) can be easily removed from the receiving part (7) by holding the separation band (19).

[0104] In addition, as described above, if the band groove (21) is formed on the basic coupling surface (13) of the main body (1) and the end of the separation band (19) is received, the separation band (19) does not interfere with the coupling between the main body (1) and the controller (3), and even when various sealing is performed between the main body (1) and the controller (3), the separation band (19) does not act as a separate obstacle.

[0105]

[0106] FIGS. 9 and FIGS. 10 illustrate another embodiment of the protective cap (9) of the present invention, wherein the surface of the protective cap (9) is provided with a vent groove (23) formed to facilitate air discharge between the receiving portion (7) and the protective cap (9) when the protruding part (5) is assembled.

[0107] When the skirt portion (17) is provided at the entrance of the protective cap (9), a vent hole (25) communicating with the vent groove (23) is formed in the skirt portion (17).

[0108] Accordingly, when the protruding part (5) of the controller (3) covered with the protective cap (9) is inserted into the receiving part (7) of the main body (1), the air between the receiving part (7) and the protective cap (9) is not trapped and is easily discharged through the vent groove (23) and the vent hole (25), thereby ultimately improving the assembly of the controller (3) and the main body (1).

[0109] Of course, the vent groove (23) and vent hole (25) as described above allow external air to be easily introduced into the space between the receiving portion (7) and the protective cap (9) even when the protective cap (9) is separated from the receiving portion (7), thereby enabling smoother separation of the protective cap (9).

[0110]

[0111] Meanwhile, the protective cap used in the present invention as described above may be expressed as follows.

[0112] That is, an embodiment of the protective cap for protecting a part according to the present invention is formed in a bowl shape to wrap around the end and circumference of a protruding part (5); and a plurality of cushioning ribs (11) may be formed on the surface.

[0113] A skirt portion (17) with a shape that expands the opening cross-sectional area can be integrally formed at the entrance portion of the above protective cap (9).

[0114] A vent groove (23) is provided on the surface of the protective cap (9) along the opening direction of the protective cap (9); and a vent hole (25) communicating with the vent groove (23) may be formed in the skirt portion (17).

[0115] A separation band (19) extending integrally toward the opening direction of the protective cap (9) may be provided at the entrance portion of the protective cap (9).

[0116]

[0117] Although specific embodiments of the present invention have been illustrated and described, it is obvious to those skilled in the art that the present invention can be modified and changed in various ways without departing from the technical spirit of the invention as provided by the following claims.
