[0026] Referring to the drawings, the heavy-duty motor bracket structure according to the present invention comprises a base bracket plate (210), a core bracket part (213), an outer reinforcing bracket part (215), and a plurality of core-side connecting reinforcing ribs (217) as basic components.

[0027] The above base bracket plate (210) is configured in a plate shape of a certain thickness. In the present invention, the base bracket plate (210) is configured in a square plate shape. The present invention is a heavy-duty motor bracket structure coupled to a heavy-duty motor, wherein the base bracket plate (210) is a base bracket plate for supporting the heavy-duty motor.

[0028] The core bracket portion (213) is provided on the inner surface of the base bracket plate (210). The core bracket portion (213) has a loop-shaped bracket wall shape, and the lower end of the core bracket portion (213) is integrally connected to the inner surface of the base bracket plate (210), so that the core bracket portion (213) protrudes to a certain height from the inner surface of the base bracket plate (210).

[0029] The outer reinforcing bracket part (215) is provided on the outer side of the core bracket part (213). The outer reinforcing bracket part (215) and the core bracket part (213) have a loop-shaped bracket wall shape, and the lower end of the outer reinforcing bracket part (215) is integrally connected to the inner surface of the base bracket plate (210), so that the outer reinforcing bracket part (215) protrudes to a certain height from the inner surface of the base bracket plate (210).

[0030] At this time, the core bracket portion (213) is composed of the innermost inner core bracket portion (213A), an intermediate core bracket portion (213B) positioned on the outer side of the inner core bracket portion (213A), and an outer core bracket portion (213C) positioned on the outer side of the intermediate core bracket portion (213B). The heights of the inner core bracket portion (213A) and the intermediate core bracket portion (213B) are formed to be lower than the height of the outer core bracket portion (213C).

[0031] Accordingly, the present invention is configured such that the core bracket portion (213) is composed of three inner core bracket portions (213A), an intermediate core bracket portion (213B), and an outer core bracket portion (213C), thereby further reinforcing the integrated connection structure between the base bracket plate (210), the inner core bracket portion (213A), the intermediate core bracket portion (213B), and the outer core bracket portion (213C), so that the effect of reliably increasing the supporting force in the central part of the base bracket plate (210), which is the main part supporting the heavy-weight motor, can be expected. In other words, the present invention is configured such that the core bracket portion (213) is composed of three inner core bracket portions (213A), an intermediate core bracket portion (213B), and an outer core bracket portion (213C). By further reinforcing the integrated connection structure between the base bracket plate (210), the inner core bracket portion (213A), the intermediate core bracket portion (213B), and the outer core bracket portion (213C), it is possible to expect the effect of significantly increasing the supporting force that supports and holds up the central part of the heavy-duty motor bracket structure of the present invention.

[0032] The core-side connecting reinforcing rib (217) is connected to the core bracket portion (213) and the base bracket plate (210). A plurality of core-side connecting reinforcing ribs (217) are configured in a radial arrangement branched out in a sunbeam shape with respect to the center of the base bracket plate (210) when viewed from the inner surface of the base bracket plate (210).

[0033] At this time, the outer reinforcing bracket part (215) is composed of a first outer reinforcing bracket part (215A) positioned on the outer side of the outer core bracket part (213C) and a second outer reinforcing bracket part (215B) positioned on the outer side of the first outer reinforcing bracket part (215A).

[0034] Accordingly, since the outer reinforcing bracket part (215) is arranged in a concentric shape with two first outer reinforcing bracket parts (215A) and a second outer reinforcing bracket part (215B), the integrated connection structure between the base bracket plate (210), the first outer reinforcing bracket part (215A), and the second outer reinforcing bracket part (215B) is further strengthened, thereby allowing for the effect of increasing the support force for supporting heavy-duty motors.

[0035] One of the important aspects of the present invention is that the base bracket plate (210), the core bracket part (213), the first outer reinforcing bracket part (215A), and the core-side connecting reinforcing rib (217) are made of plastic, which allows for weight reduction compared to metal.

[0036] Meanwhile, in the present invention, the central part of the base bracket plate (210) is provided with a plate hole (211) (210PH) that penetrates through both sides, and the plate hole (211) is positioned in the inner region of the core bracket part (213). Specifically, the plate hole (211) is provided in the inner region of the inner core bracket part (213A) constituting the core bracket part (213). The plate hole (211) may be configured to allow a motor shaft provided in a heavy-duty motor to be coupled thereto.

[0037] In addition, a plurality of side support ribs (218) are connected to the outer reinforcing bracket portion (215), and the plurality of side support ribs (218) are connected to the inner surface of the base bracket plate (210).

[0038] Specifically, the inner end of a plurality of side support ribs (218) is connected to the outer surface of a second outer reinforcement bracket (215B) constituting the outer reinforcement bracket (215), and the lower end of a plurality of side support ribs (218) is connected to the inner surface of the base bracket plate (210).

[0039] In the present invention, a plurality of the side support ribs (218) are configured in a downwardly inclined protruding shape toward the inner surface of the base bracket plate (210).

[0040] Accordingly, the connection strength between the base bracket plate (210) and the second outer reinforcement bracket part (215B) of the outer reinforcement bracket part (215) can be increased by the plurality of side support ribs (218), while minimizing the material for forming the motor bracket.

[0041] Additionally, it further includes a plurality of outward reinforcing connecting rib pieces (219) that are integrally connected to the core bracket portion (213) and the first outer reinforcing bracket portion (215A) and are arranged to extend radially from the center of the base bracket plate (210).

[0042] Specifically, the outward reinforcing connecting rib piece (219) is composed of a first outward reinforcing connecting rib piece (219A) with both ends connected to a first outer reinforcing bracket part (215A) constituting an outer reinforcing bracket part (215), and a second outward reinforcing connecting rib piece (219B) with both ends connected to the first outward reinforcing connecting rib piece (219A) and the second outer reinforcing bracket part (215B).

[0043] Accordingly, since the first outward reinforcing connecting rib piece (219A) and the second outward reinforcing connecting rib piece (219B) are branched out and extended in a sunbeam shape and are integrally connected to the core bracket part (213) and the first outer reinforcing bracket part (215A), the present invention has the effect of further strengthening the integral connection structure between the core bracket part (213), the first outer reinforcing bracket part (215A), and the base bracket plate (210).

[0044] Meanwhile, the present invention is further provided with a plurality of fastening groove portions (219G) positioned between the core bracket portion (213) and the first outer reinforcing bracket portion (215A), and is characterized in that a fastening boss (219CB) is provided in the fastening groove portions.

[0045] Specifically, the structure has a concave groove (219G) for fastening connection between the outer core bracket part (213C) constituting the core bracket part (213) and the first outer reinforcing bracket part (215A) constituting the outer reinforcing bracket part (215), and the fastening boss (219CB) is provided in the concave groove (219G) for fastening connection.

[0046] A plurality of the above-mentioned concave grooves (219G) for fastening and a plurality of fastening bosses (219CB) are arranged radially with respect to the center of the base bracket plate (210). In the present invention, the above-mentioned concave grooves (219G) for fastening and a plurality of fastening bosses (219CB) are arranged at four locations with respect to the center of the base bracket plate (210).

[0047] Accordingly, by attaching a fastener that is coupled to the fastening boss (219CB) to mount a heavy-duty motor, the heavy-duty motor bracket structure of the present invention can be more stably coupled to the heavy-duty motor.

[0048] Meanwhile, in the present invention, the concave groove portion (219G) for fastening connection is provided with a boss connecting reinforcing piece (219BSP) disposed on the outer side of the fastening boss (219CB), and a plurality of boss auxiliary reinforcing pieces (219BSR) are connected between the boss connecting reinforcing piece (219BSP) and the outer surface of the fastening boss (219CB).

[0049] Accordingly, the present invention supports the outer surface of the fastening boss (219CB) and the boss connecting reinforcing piece (219BSP) and the outer surface of the fastening boss (219CB) by strongly connecting and holding the boss auxiliary reinforcing piece (219BSR), thereby enabling the heavy-duty motor bracket structure of the present invention to be more stably coupled to the heavy-duty motor.

[0050] In addition, in the present invention, all of the above-mentioned components, such as the base bracket plate (210), the core bracket part (213), the first outer reinforcing bracket part (215A), and a plurality of core-side connecting reinforcing ribs (217), are made of plastic, thereby realizing an optimized structure tailored to the weight and shape of the motor. Furthermore, by utilizing the lightness and ease of molding of plastic (improving production speed and ensuring uniform quality through a plastic injection molding process), the overall weight of the product is reduced, while simultaneously achieving the effect of reducing manufacturing costs and securing mass production efficiency.

[0051] Meanwhile, the present invention further includes a plurality of plate-side line-shaped reinforcing pieces (219LP) protruding from the inner surface of the base bracket plate (210).

[0052] The above plate-side line-shaped reinforcing piece (219LP) is also made of plastic and is integrally connected to the inner surface of the base bracket plate (210).

[0053] The above-mentioned plate-side line-shaped reinforcing piece (219LP) is provided at the location where a mounting hole is formed through both sides of the base bracket plate (210). The above-mentioned plate-side line-shaped reinforcing piece (219LP) protrudes to a certain height from the inner surface of the base bracket plate (210).

[0054] The above plate-side line-shaped reinforcing members (219LP) are arranged at multiple locations based on the center of the base bracket plate (210). In the present invention, the multiple plate-side line-shaped reinforcing members (219LP) have a structure arranged radially based on the center of the base bracket plate (210).

[0055] Accordingly, the present invention further reinforces the strength of the base bracket plate (210) itself through a plurality of plate-side line-shaped reinforcing pieces (219LP), thereby reducing thermal deformation caused by heat, including the base bracket plate (210) and all the aforementioned components, and reliably prevents damage such as breakage due to external force.

[0056] At this time, the plate-side line-shaped reinforcing piece (219LP) is further provided with an empty reinforcing piece-side hollow portion (219VP). The reinforcing piece-side hollow portion (219VP) can be described as a groove in which a part of the plate-side line-shaped reinforcing piece (219LP) is left empty.

[0057] Accordingly, the present invention provides a plurality of plate-side line-shaped reinforcing pieces (219LP) protruding from the base bracket plate (210) to provide strong resistance to thermal deformation and external forces, while reducing the amount of material used by the hollow portion (219VP) on the reinforcing piece side, thereby helping to reduce material costs and lower unit costs.

[0058] Meanwhile, FIG. 8 is a perspective view of a heavy-duty motor bracket structure according to another embodiment of the present invention, FIG. 9 is an enlarged view of part C of FIG. 8, FIG. 10 is a plan view of FIG. 8, FIG. 11 is a perspective view of a heavy-duty motor bracket structure according to yet another embodiment of the present invention, showing an embodiment in which the cross-shaped connecting reinforcing rib, which is a main part, gradually increases in cross-sectional area as it goes toward the base bracket plate, FIG. 12 is an enlarged view of part D of FIG. 11, and FIG. 13 is a longitudinal cross-sectional view along line AA of FIG. 12.

[0059] Referring to the drawings, the present invention is characterized in that a space (SP) is formed between two adjacent first outer reinforcing connecting ribs (219A) among a plurality of first outer reinforcing connecting ribs (219A) that form the outer reinforcing connecting rib (219) and an outer core bracket part (213C) constituting the core bracket part (213), a first outer reinforcing bracket part (215A) constituting the outer reinforcing bracket part (215), and a cross-shaped connecting reinforcing rib (223) is provided in the space (SP), and the cross-shaped connecting reinforcing rib (223) is connected to the outer core bracket part (213C), the first outer reinforcing bracket part (215A), and two adjacent first outer reinforcing connecting ribs (219A), and the lower end of the cross-shaped connecting reinforcing rib (223) is connected to the inner surface of the base bracket plate (210). does.

[0060] Accordingly, the present invention has the effect of further increasing the supporting force that allows the base bracket plate (210), the core bracket (213A), and the outer core bracket (213C) constituting the core bracket (213) and the outer reinforcing bracket (215A) constituting the outer reinforcing bracket (215) to be strongly connected and supported by the cross-shaped connecting reinforcing rib (223).

[0061] In addition, in the present invention, the cross-shaped connecting reinforcing rib (223) is configured such that its cross-sectional area gradually increases from top to bottom. Since the force with which the cross-shaped connecting reinforcing rib (223) connects the core bracket part (213) and the outer reinforcing bracket part (215) to the base bracket plate (210) increases as it goes down the cross-shaped reinforcing rib, it is possible to expect an effect of further increasing the supporting force that enables the base bracket plate (210), the core bracket part (213), and the outer reinforcing bracket part (215) to support and withstand a heavy-duty motor.
