The straight portion 251 may extend along a straight line and connect the body portion 210 to the front fastening portion 230. The curved portion 252 may extend along a curve and connect the body portion 210 to the front fastening portion 230.

[0098] The straight portion 251 and the curved portion 252 may be spaced apart from each other, and the reinforcing rib 253 may connect the straight portion 251 to the curved portion 252. A plurality of reinforcing ribs 253 may be provided and may connect the straight portion 251 to the curved portion 252. Rib grooves 254 may be formed between the plurality of reinforcing ribs 253.

[0099] When the straight portion 251 and the curved portion 252 are used and the reinforcing rib 253 and the rib groove 254 are formed therebetween, the load applied to the front connection portion 242 may be effectively distributed while reducing the weight of the first front connection portion 241 .

[0100] The second front connection portion 242 according to an embodiment of the present disclosure may be formed in a rod shape. When the second front connection portion 242 may be formed in a rod shape with a varying thickness, as the second front connection portion 242 extends from the body portion 210 in a direction toward the front fastening portion 230, the thickness of the second front connection portion 242 may increase.

[0101] However, the shape of the first front connection portion 241 and the shape of the second front connection portion 242 are not limited thereto, and may vary depending on a load applied to the first front connection portion 241 and the second front connection portion 242 .

[0102] According to an embodiment of the present disclosure, the first front connection portion 241, the second front connection portion 242, and one side of the main body portion 210 may be formed in a triangular shape. Fig.11 , a line connecting the portion where the main body 210 is connected to the first front connection portion 241 to the portion where the main body 210 is connected to the second front connection portion 242, an extension line of the first front connection portion 241, and an extension line of the second front connection portion 242 can form a triangular shape.

[0103] refer to Fig.11 , an angle formed between a first straight line 243 intersecting the center of the first front connection portion 241 and a second straight line 244 intersecting the center of the second front connection portion 242 may be 20 degrees to 80 degrees.

[0104] In order to make the first front connection portion 241, the second front connection portion 242, and a side surface of the main body 210 form a triangular shape, the angle formed between the first straight line 243 intersecting with the center of the first front connection portion 241 and the second straight line 244 intersecting with the center of the second front connection portion 242 can be 20 degrees to 80 degrees.

[0105] Here, the first straight line 243 intersecting the center of the first front connection portion 241 may be a line connecting the center of the portion where the main body 210 connects to the center of the portion where the first front connection portion 241 is located to the center of the portion where the front fastening portion 230 connects to the second front connection portion 242. In addition, the second straight line 244 intersecting the center of the second front connection portion 242 may be a line connecting the center of the portion where the main body 210 connects to the second front connection portion 242 to the center of the portion where the front fastening portion 230 connects to the second front connection portion 242.

[0106] When the first front connection portion 241 , the second front connection portion 242 , and one side surface of the body portion 210 according to the embodiment form a triangular shape, the load applied to the front mount 220 may be effectively distributed.

[0107] The rear mounting member 260 may be disposed on the rear portion 212 of the body portion 210 and may include a rear fastening hole 271. The rear mounting member 260 may protrude from the rear portion 212 of the body portion 210 in a circumferential direction and may include a rear fastening hole 271 that may be coupled to the tub 10 of the washing machine.

[0108] refer to Figure 5 and Figure 6 , a second fastening protrusion 22 may be provided on the rear surface 12 of the tub 10 of the washing machine, and the second fastening protrusion 22 may be inserted into the rear fastening hole 271. Figure 5 and Figure 6 , when the second fastening protrusion 22 is inserted into the rear fastening hole 271 of the rear mount 260, the rear mount 260 may be assembled to be connected to the tub 10 of the washing machine.

[0109] According to an embodiment of the present disclosure, the second fixing member 272 may be inserted into the rear fastening hole 271 of the rear mount 260, and in a state where the second fixing member 272 is inserted into the rear fastening hole 271, the second fastening protrusion 22 may be inserted into the rear fastening hole 271. The second fixing member 272 may be tightly fitted to the second fastening protrusion 22, and a hole having a diameter smaller than that of the second fastening protrusion 22 may be formed in the second fixing member 272.

[0110] According to an embodiment of the present disclosure, a cutout groove 273 may be formed on the outer portion of the second fixing member 272. The second fixing member 272 may be inserted into the rear fastening hole 271 while being deformed by the cutout groove 273.

[0111] The second fixing member 272 may include an elastic material, and when the second fixing member 272 is deformed by the cutout groove 273, a restoring force for returning to an original state may be generated in the second fixing member 272. By the restoring force, the second fixing member 272 may be inserted into the rear fastening hole 271 without separation.

[0112] According to an embodiment of the present disclosure, after the second fixing member 272 is inserted into the rear fastening hole 271, the second fastening protrusion 22 may be inserted into the rear fastening hole 271. Figure 5 and Figure 6 According to an embodiment of the present disclosure, the coupling protrusion 24 may be provided on the outside of the second fastening protrusion 22. When the second fastening protrusion 22 is inserted into the rear fastening hole 271, the coupling protrusion 24 of the second fastening protrusion 22 may be pressed against the inside of the rear fastening hole 271, and the second fastening protrusion 22 may be securely coupled to the rear fastening hole 271.

[0113] The first and second fastening protrusions 21 and 22 according to an embodiment of the present disclosure may be provided on the rear surface 12 of the tub 10 of the washing machine and may be spaced apart from each other.

[0114] refer to Figure 5 The front mounting member 220 and the rear mounting member 260 can be respectively assembled to be connected to the first fastening protrusion 21 and the second fastening protrusion 22 provided in the barrel 10 of the washing machine, and the front mounting member 220 and the rear mounting member 260 can be assembled to be connected to the barrel 10 of the washing machine while being spaced apart from each other.

[0115] The rear mount 260 according to an embodiment of the present disclosure may include a rear fastening portion provided with a rear fastening hole 271 and a rear connecting portion 280 having one side connected to the rear fastening portion 270 and the other side connected to the body portion 210 .

[0116] The rear fastening portion 270 may be provided with a rear fastening hole 271 and may protrude in a circumferential direction of the body portion 210. The rear connecting portion 280 may connect the rear fastening portion 270 to the body portion 210.

[0117] The end of the rear mounting member 260 according to the embodiment of the present disclosure may protrude more outward than the rear portion 212 of the main body portion 210. Fig. 9 , an end portion of the rear mounting member 260 may protrude to the outside toward a direction that the rear portion 212 of the main body portion 210 faces.

[0118] For example, the end of the rear fastening portion 270 of the rear mounting member 260 may protrude more outward than the rear portion 212 of the main body 210. The rear connecting portion 280 according to an embodiment of the present disclosure may extend to the outside toward the direction in which the rear portion 212 of the main body 210 faces, and the rear fastening portion 270 may be connected to the main body 210 through the rear connecting portion 280.

[0119] When the rear fastening portion 270 is connected to the main body 210 through the rear connecting portion 280, since the rear connecting portion 280 extends to the outside in the direction facing the rear portion 212 of the main body 210, the end of the rear fastening portion 270 may protrude more outward than the rear portion 212 of the main body 210, such as Fig. 9 shown.

[0120] When the end of the rear mount 260 protrudes more outward than the rear portion 212 of the body 210 , the size of the stator 110 and the size of the rotor 121 may be easily changed without changing the spacing distance between the front mount 220 and the rear mount 260 .

[0121] In order to increase the rotation force of the motor, it is necessary to use a motor with a large size, and depending on the size of the motor, the size of the stator 110 and the size of the rotor 121 may be changed. According to an embodiment of the present disclosure, the stator 110 and the rotor 121 may be stacked and used depending on the size of the motor.

[0122] In order to additionally stack the stator 110 and the rotor 121, depending on the size of the motor, it is necessary to increase the size of the body 210. Since the pulley 124 and the belt are provided in the direction in which the front mount 220 is provided, it is difficult to increase the size of the body 210 in the direction in which the front mount 220 is provided.

[0123] However, when the end of the rear mount 260 protrudes more outward than the rear portion 212 of the body 210 , the spacing distance between the front mount 220 and the rear mount 260 may not change even when the size of the body 210 is increased in the direction of the rear portion 212 .

[0124] For example, refer to Fig. 9 , the end of the rear mounting member 260 protrudes outward more than the rear portion 212 of the main body 210 , thereby creating a space for changing the size of the main body 210 .

[0125] Therefore, even when the size of the body portion 210 is increased in the direction toward the rear portion 212 in order to additionally stack the stator 110 and the rotor 121 , the spacing distance between the front mount 220 and the rear mount 260 does not change.

[0126] As described above, when the end of the rear mounting member 260 according to the embodiment protrudes outward more than the rear portion 212 of the main body 210, the size of the main body 210 can be changed without changing the spacing distance between the front mounting member 220 and the rear mounting member 260, so that the stator 110 and the rotor 121 can be additionally stacked.

[0127] A plurality of front mounts 220 may be disposed on the front portion 211 of the main body 210 , and one or more rear mounts 260 may be disposed on the rear portion 212 of the main body 210 .

[0128] refer to Figure 8 According to an embodiment of the present disclosure, two front mounting members 220 may be disposed on the front surface of the main body 210 , and when one rear mounting member 260 is disposed on the rear surface of the main body 210 , the one rear mounting member 260 may be disposed between the two front mounting members 220 .

[0129] When a rear mounting member 260 is disposed between two front mounting members 220 , an extension line of a direction along which a rear fastening hole 271 of the rear mounting member 260 extends is arranged between extension lines of directions along which the front fastening holes 231 in each of the two front mounting members 220 extend.

[0130] The front mount 220 is a site that receives the greatest force when the rotating tub (basket) is rotated by the stator 110 , the rotor 121 , and the rotating shaft 122 , and when two front mounts 220 are provided in the body part 210 , the force may be dispersed.

[0131] In this case, vibration or lifting may occur between the two front mounts 220 that disperse the force. According to an embodiment of the present disclosure, when one rear mount 260 is disposed between the two front mounts 220, the one rear mount 260 between the two front mounts 220 disperses the force, thereby preventing vibration or lifting from occurring between the two front mounts 220.

[0132] According to an embodiment of the present disclosure, a structure can be obtained among the first circle C1 of the main body 210, the third circle C3 which is concentric with the first circle C1 and passes through the center of the front fastening hole 231, and the second circle C2 which is concentric with the first circle C1 and passes through the center of the rear fastening hole 271, in which: the size of the diameter of the first circle C1 < the size of the diameter of the second circle C2 < the size of the diameter of the third circle C3.

[0133] refer to Figure 8 According to an embodiment of the present disclosure, the body part 210 may be formed in a circular shape, and the first circle C1 may be a circle corresponding to the body part 210 having a circular shape. The center of the first circle C1 may coincide with the center of the body part 210, and the first circle C1 may be formed along the outer shape of the body part 210 having a circular shape.

[0134] The second circle C2 may be concentric with the first circle C1 and may pass through the center of the rear fastening hole 271. The center of the second circle C2 may be the same as the center of the first circle C1, and the center of the second circle C2 may coincide with the center of the body part 210.

[0135] The second circle C2 may pass through the center of the rear fastening hole 271, and the second circle C2 may be a circle whose radius is a line connecting the center of the main body 210 to the center of the rear fastening hole 271, and the circle is formed by rotating in a circumferential direction based on the center of the main body 210.

[0136] The third circle C3 may be concentric with the first circle C1 and may pass through the center of the front fastening hole 231. The center of the third circle C3 may be identical to the center of the first circle C1, and the center of the third circle C3 may be identical to the center of the body part 210.

[0137] The third circle C3 may pass through the center of the front fastening hole 231, and the third circle C3 may be a circle whose radius is a line connecting the center of the main body 210 to the center of the front fastening hole 230, and the circle is formed by rotating in a circumferential direction based on the center of the main body 210.

[0138] According to an embodiment of the present disclosure, the size of the diameter of the third circle C3 may be greater than the size of the diameter of the second circle C2, and the size of the diameter of the second circle C2 may be greater than the size of the diameter of the first circle C1. Because the front mounting member 220 protrudes from the front surface of the main body 210 in the circumferential direction, and the rear mounting member 260 protrudes from the rear portion 212 of the main body 210 in the circumferential direction, the size of the diameter of the second circle C2 and the size of the diameter of the third circle C3 may both be greater than the size of the diameter of the first circle C1.

[0139] Furthermore, according to an embodiment of the present disclosure, the diameter of the third circle C3 may be larger than that of the second circle C2 , and in this way, the front fastening hole 231 may protrude more outward from the center of the body portion 210 than the rear fastening hole 271 .

[0140] The front mount 220 may be a portion where the greatest force is applied when the rotating tub (basket) is rotated by the stator 110, the rotor 121, and the rotating shaft 122. According to an embodiment of the present disclosure, when the size of the diameter of the third circle C3 is greater than the size of the diameter of the second circle C2 so that the front fastening hole 231 protrudes more outward from the center of the body part 210 than the rear fastening hole 271, the force applied to the body part 210 may be easily dispersed to the tub 10 through the front mount 220.

[0141] When the force is dispersed by the front mounting member 220, vibration or lifting may occur between the two front mounting members 220. According to an embodiment of the present disclosure, when the size of the diameter of the second circle C2 is smaller than the size of the diameter of the third circle C3 so that the rear fastening hole 271 does not protrude more to the outside of the body part 210 than the front fastening hole 231, the vibration or lifting between the two front mounting members 220 can be prevented by the rear mounting member 260.

[0142] According to the embodiment of the present disclosure, the main body 210, the front mounting member 220 and the rear mounting member 260 may be integrally injection molded. When the main body 210, the front mounting member 220 and the rear mounting member 260 are integrally injection molded at the same time, an additional mounting member for assembling the motor fixing structure 100 to the tub 10 of the washing machine may not be assembled.

[0143] In this way, the strength and size of the motor fixing structure 100 can be reduced, and when the main body 210, the front mount 220, and the rear mount 260 are simultaneously integrally injection-molded, the manufacturing accuracy can also be improved.

[0144] In addition, the body 210, the front mounting member 220 and the rear mounting member 260 according to the embodiment of the present disclosure may be integrally die-casted by metal objects. According to the embodiment of the present disclosure, die casting is a precision casting method in which molten metal is injected into a mold to obtain a casting identical to the mold.

[0145] According to an embodiment of the present disclosure, in order to integrally manufacture the body 210 , the front mount 220 , and the rear mount 260 , a mold corresponding to the shapes of the body 210 , the front mount 220 , and the rear mount 260 may be manufactured.

[0146] When a mold corresponding to the shapes of the body 210 , the front mount 220 , and the rear mount 260 is manufactured, molten metal may be injected into the mold to integrally manufacture the body 210 , the front mount 220 , and the rear mount 260 by metal objects.

[0147] As described above, when the main body 210, the front mounting member 220 and the rear mounting member 260 are integrally manufactured by die casting of metal objects, the dimensional accuracy can be improved. In addition, since the size is accurate, no trimming is required, and thus a motor fixing structure with excellent mechanical properties can be manufactured.

[0148] The motor fixing structure 100 according to the embodiment of the present disclosure may be provided in the body part 210 , and may further include a terminal part 290 provided with a connection terminal 291 connected to the stator 110 .

[0149] The terminal part 290 is provided with a connection terminal 291 for supplying power to the stator 110 , and the stator 110 may be connected to the connection terminal 291 to receive power through the connection terminal 291 .

[0150] Fig.12 2 is a schematic perspective view illustrating that the stator 110 and the terminal part 290 are insert-molded, and then the body part 210 is injection-molded according to an embodiment of the present disclosure. Fig.12 , the body part 210 according to the embodiment of the present disclosure may be injection-molded after the stator 110 is inserted.

[0151] For example, when the body 210 is injection molded, the stator 110 may be inserted into a mold, and then the body 210 may be injection molded. In this case, when the body 210 is injection molded, the front mount 220 and the rear mount 260 may be integrally injection molded with the body 210.

[0152] When the stator 110 is manufactured together with the body part 210 by insert injection molding, an additional assembling member for assembling the stator 110 to the body part 210 may not be required. In this way, productivity of the motor fixing structure may be improved.

[0153] In addition, the main body 210 according to the embodiment of the present disclosure may be injection molded after inserting the terminal part 290. For example, when the main body 210 is injection molded, the terminal part 290 may be inserted into the mold, and then the main body 210 may be injection molded. In this case, when the main body 210 is injection molded, the front mounting member 220 and the rear mounting member 260 may be integrally injection molded together with the main body 210.

[0173] Press-fitting is pushing into a narrow hole or groove, and the fixing groove 213 according to an embodiment of the present disclosure may be a groove having a width smaller than that of the fixing bearing 123. When the fixing bearing 123 is pushed into the fixing groove 213, the fixing bearing 123 may be press-fitted into the fixing groove 213, so that the rotor 121 and the rotating shaft 122 may be assembled inside the body part 210.

[0174] After the rotor 121 and the rotating shaft 122 are assembled to be connected to the body part 210, the coupling cover 125 may be press-fitted into the body part 210. Fig.12 According to an embodiment of the present disclosure, an inner groove 214 having a width smaller than that of the connecting cover 125 may be provided inside the main body 210 , and when the connecting cover 125 is pushed into the inner groove 314 of the main body 210 , the connecting cover 125 may be assembled to be connected to the main body 210 .

[0175] refer to Fig.14 and Fig.15 When the coupling cover 125 is press-fitted into the main body 210, the caulking protrusion 128 of the coupling cover 125 may be tightly fitted into the inner groove 214 of the main body 210. On the side surface of the caulking protrusion 128, a downwardly inclined surface may be formed in the direction along which the coupling cover 125 is inserted into the main body 210, and the coupling cover 125 may be inserted into the inner groove 214 of the main body 210 along the downwardly inclined surface of the caulking protrusion 128.

[0176] When the coupling cover 125 is press-fitted into the body part 210 , the caulking protrusion 128 of the coupling cover 125 may be tightly fitted into the inner groove 214 of the body part 210 , and the caulking protrusion 128 may be pressed by the inner groove 214 of the body part 210 .

[0177] When the caulking protrusion 128 of the coupling cover 125 is pressed by the inner groove 214 of the body part 210, the caulking protrusion 128 may be deformed. When the caulking protrusion 128 is deformed, a restoring force for returning to an original state may be generated in the caulking protrusion 128, so that the coupling cover 125 may be firmly coupled to the body part 210.

[0178] The strength of the coupling cover 125 and the caulking protrusion 128 according to an embodiment of the present disclosure may each be greater than the strength of the body part 210. For example, the coupling cover 125 and the caulking protrusion 128 according to an embodiment of the present disclosure may include iron, and the body part 210 may include a plastic injection molding (resin).

[0179] Since the strength of the caulking protrusion 128 is greater than that of the body 210, the caulking protrusion 128 must destroy the body 210 in order to separate the caulking protrusion 128 from the body 210. Therefore, by the caulking protrusion 128, the coupling cover 125 and the body 210 can be further firmly coupled to each other at high temperatures.

[0180] A coupling groove 126 may be provided in the coupling cover 125 , and when the coupling cover 125 is press-fitted into the body part 210 , a portion of the rotation shaft 122 may pass through the coupling groove 126 and protrude to the outside of the body part 210 .

[0181] When the coupling cover 125 is press-fitted into the body part 210, the coupling bearing 127 provided at one side of the rotor 121 and coupled to the rotating shaft 122 may be press-fitted into the coupling groove 126. The coupling groove 126 of the coupling cover 125 may be a groove having a width smaller than that of the coupling bearing 127, and when the coupling bearing 127 is press-fitted into the coupling groove 126, one side of the rotating shaft 122 may be fixed to the coupling cover 125.

[0182] As described above, the other side of the rotating shaft 122 mounted on the rotor 121 may be fixed to the fixing groove 213 inside the body part 210 by the fixing bearing 123, and one side of the rotating shaft 122 may be fixed to the coupling groove 126 of the coupling cover 125 by the coupling bearing 127. In this way, the rotor 121 and the rotating shaft 122 may be assembled to be connected to the body part 210.

[0183] A process of assembling the motor fixing structure 100 to the washing machine 1 according to an embodiment of the present disclosure is described below.

[0184] The motor fixing structure 100 according to an embodiment of the present disclosure may be assembled to be connected with the washing machine 1 through the tub 10 , and the motor fixing structure 100 may be coupled to the tub 10 through first and second fastening protrusions 21 and 22 provided on the rear surface 12 of the tub 10 .

[0185] For example, when the first fastening protrusion 21 is inserted into the front fastening hole 231 of the motor fastening structure 100 and the second fastening protrusion 22 is inserted into the rear fastening hole 271 of the motor fastening structure 100 , the motor fastening structure 100 may be coupled to the rear surface 12 of the tub 10 .

[0186] According to an embodiment of the present disclosure, when the first fastening protrusion 21 is inserted into the front fastening hole 231 of the motor fixing structure 100 and the second fastening protrusion 22 is inserted into the rear fastening hole 271, the first fixing part 232 and the second fixing part 272 can be used to prevent the first fastening protrusion 21 and the second fastening protrusion 22 from being separated from the front fastening hole 231 and the rear fastening hole 271.

[0187] According to an embodiment of the present disclosure, when the motor fixing structure 100 is coupled to the tub 10, after the first fixing member 232 is inserted into the front fastening hole 231, the first fastening protrusion 21 may be inserted into the front fastening hole 231. In addition, when the motor fixing structure 100 is coupled to the tub 10, after the second fixing member 272 is inserted into the rear fastening hole 271, the second fastening protrusion 22 may be inserted into the rear fastening hole 271.

[0188] As described above, after the first fixing part 232 is inserted into the front fastening hole 231, the first fastening protrusion 21 can be inserted into the front fastening hole 231, and after the second fixing part 272 is inserted into the rear fastening hole 271, the second fastening protrusion 22 can be inserted into the rear fastening hole 271, so that the motor fixing structure 100 can be connected to the barrel 10.

[0189] According to an embodiment of the present disclosure, the pulley 124 to which the belt 41 is connected may be provided on one side of the rotating shaft 122, and the rotating barrel pulley 42 connected to the rotating shaft 40 through the driving shaft 43 may be provided on the rear surface 12 of the barrel 10. After the motor fixing structure 100 is coupled to the rear surface 12 of the barrel 10, the pulley 124 of the rotating shaft 122 and the belt 41 of the rotating barrel pulley 42 may be connected to each other.

[0190] According to an embodiment of the present disclosure, when the rotating shaft 122 rotates by the interaction between the stator 110 and the rotor 121, the pulley 124 provided on one side of the rotating shaft 122 may rotate. When the pulley 124 rotates, the belt 41 connected to the pulley 124 may rotate, and by the rotation of the belt 41, the rotating barrel pulley 42 may rotate. When the rotating barrel pulley 42 rotates, the rotating barrel 40 connected to the rotating barrel pulley 42 through the driving shaft 43 may rotate.

[0191] The motor fixing structure 100 and the washing machine 1 including the motor fixing structure 100 according to the embodiment of the present disclosure may have the effects as described below.

[0192] Fig.18 310 and the rear bracket 320 are separated from each other. In order to fix the motor including the stator 330 and the rotor 340 to the tub of the washing machine, a structure in which the front bracket 310 and the rear bracket 320 are separated from each other may be used.

[0193] By arranging the stator 330 and the rotor 340 between the front bracket 310 and the rear bracket 320 and coupling the bolt 350 to the nut 351, the Fig.18 The motor fixing structure.

[0194] By coupling the front mounting member 311 provided in the front bracket 310 to the coupling protrusion of the tub of the washing machine, and coupling the rear mounting member 321 provided in the rear bracket 320 to the coupling protrusion of the tub of the washing machine, the washing machine can be Fig.18 The motor fixing structure is assembled and connected to the washing machine.

[0195] Fig.18 The motor fixing structure may use at least four bolts to securely couple the front bracket 310 to the rear bracket 320. In addition, in a motor fixing structure in which the front bracket 310 and the rear bracket 320 are separated from each other, in order to couple the separated front bracket 310 and the rear bracket 320 to the tub, two mounting members may be coupled to each of the front bracket 310 and the rear bracket 320, and thus four mounting members may be required.

[0196] In addition, when Fig.18 When the front bracket 310 and the rear bracket 320 are assembled as in the motor fixing structure, in order to maintain the strength of the assembled parts, the front bracket 310 and the rear bracket 320 must be made of metal materials.

[0197] However, in Fig.18 In the motor fixing structure shown, since the front bracket 310 and the rear bracket 320 must be coupled to each other by the bolts 350, productivity is reduced, and since two additional mounting members must be provided to assemble each of the front bracket 310 and the rear bracket 320, it is difficult to ensure dimensional accuracy during assembly.

[0198] In addition, in Fig.18 In the motor fixing structure shown, since the front bracket 310 and the rear bracket 320 must be coupled to each other by the bolts 350 and the front mount 311 and the rear mount 321 must be coupled to the front bracket 310 and the rear bracket 320, respectively, when tolerance occurs, tolerance is accumulated due to assembly.

[0199] However, the motor fixing structure 100 according to the embodiment of the present disclosure is manufactured by integrally injection molding the body part 210 , the front mount 220 , and the rear mount 260 , so that the dimensional accuracy of the motor fixing structure 100 can be improved while reducing the size of the motor fixing structure.

[0200] In addition, since the motor fixing structure 100 according to the embodiment of the present disclosure is manufactured by integrally injection molding the main body 210, the front mount 220 and the rear mount 260 without assembly, the tolerance generated by the assembly can be reduced and the accumulated tolerance can be prevented from occurring as the assembly proceeds.

[0201] In addition, since the motor fixing structure 100 according to the embodiment of the present disclosure is manufactured by integrally injection molding the main body 210, the front mounting member 220 and the rear mounting member 260, there is no need to use four mounting members by connecting two mounting members to each of the front bracket and the rear bracket, and the connection strength can be maintained even when only three mounting members are used for the main body 210.

[0202] As in Fig.18 Like the motor fixing structure of the motor, when assembling the front bracket 310 and the rear bracket 320 which are separated from each other, in order to maintain the strength at the assembled portions, the front bracket 310 and the rear bracket 320 must be made of a metal material.

[0203] However, since the motor fixing structure 100 according to the embodiment of the present disclosure is manufactured by integrally injection molding the main body 210, the front mounting member 220 and the rear mounting member 260, no assembly part may be produced, and in this way, the motor fixing structure 100 may be manufactured by injection molding material.

[0204] Furthermore, since the motor fixing structure 100 according to the embodiment of the present disclosure is manufactured by integrally injection-molding the body part 210 , the front mount 220 , and the rear mount 260 , the motor fixing structure 100 may be manufactured of an injection molding material having high strength.

[0205] In such Fig.18 In the motor fixing structure shown, the front bracket 310 and the rear bracket 320 must be coupled to each other by bolts 350, and at least four bolts 350 must be used. In order to couple the front bracket 310 and the rear bracket 320 by at least four bolts 350, a space in which at least four bolts 350 can fit may be required in the front bracket 310 and the rear bracket 320.

[0206] therefore, Fig.18 The front bracket 310 and the rear bracket 320 of the motor fixing structure must be manufactured in a quadrilateral shape so that there is space for the insertion of the bolt 350. Fig.18 In the motor fixing structure, when the front bracket 310 and the rear bracket 320 are formed into a quadrilateral shape, the stator 330 connected and assembled with the front bracket 310 and the rear bracket 320 is also formed into a quadrilateral shape.

[0207] The stator 330 includes a core around which a coil is wound, and it is preferable that the core is formed in a circular shape so as to be wound, and an additional space may not be required.

[0208] Therefore, if Fig.18The motor fixing structure of the present invention has the following problems: the size of the motor is increased regardless of the performance of the motor. In addition, when the stator 330 is assembled in a state separated from the front bracket 310 and the rear bracket 320, there is a problem of corrosion due to the external exposure of the stator.

[0209] However, the motor fixing structure 100 according to the embodiment of the present disclosure is manufactured by integrally injection molding the main body 210, the front mounting member 220 and the rear mounting member 260, and since separate assembly bolts or separate mounting members are not used, the main body 210 and the stator 110 can be manufactured in a circular shape.

[0210] In the motor fixing structure 100 according to the embodiment of the present disclosure, the body part 210 and the stator 110 are manufactured in a circular shape, and thus the size of the motor is not increased regardless of the performance of the motor.

[0211] Furthermore, since the motor fixing structure 100 according to the embodiment of the present disclosure is manufactured by injection molding the body part 210 after inserting the stator 110 into the body part 210 , corrosion may be prevented by preventing external exposure of the stator 110 .

[0212] In addition, in the motor fixing structure 100 according to the embodiment of the present disclosure, the stator 110 is manufactured together with the body part 210 by insert molding, and thus no additional assembly member is required to assemble the stator 110 to the body part 210. In this way, the productivity of the motor fixing structure 100 can be improved.

[0213] Together with the above, in the motor fixing structure 100 according to the embodiment of the present disclosure, since the end of the rear mounting member 260 protrudes outward more than the rear portion 212 of the main body 210, the size of the stator 110 and the size of the rotor 121 can be easily changed without changing the spacing distance between the front mounting member 220 and the rear mounting member 260.

[0214] In order to additionally stack the stator 110 and the rotor 121, the size of the main body 210 must be increased depending on the size of the motor. Since the pulley 124 and the belt are provided in the direction in which the front mount 220 is provided, it is difficult to increase the size of the main body 210 in the direction in which the front mount 220 is provided.

[0215] However, in the motor fixing structure 100 according to the embodiment of the present disclosure, the end of the rear mounting member 260 protrudes outward more than the rear portion 212 of the main body 210, and therefore, even when the size of the main body 210 is increased in the direction toward the rear portion 212, the spacing distance between the front mounting member 220 and the rear mounting member 260 is not changed.

[0216] For example, as long as the end of the rear mounting member 260 protrudes more outward than the rear portion 212 of the main body portion 210, a space for changing the size of the main body portion 210 can be created. Therefore, even when the size of the main body portion 210 is increased in a direction toward the rear portion 212 of the main body portion 210 in order to additionally stack the stator 110 and the rotor 121, the spacing distance between the front mounting member 220 and the rear mounting member 260 is not changed.

[0217] Therefore, in the motor fixing structure 100 according to the embodiment of the present disclosure, since the end of the rear mounting member 260 protrudes outward more than the rear portion 212 of the main body 210, the size of the main body 210 can be changed without changing the spacing distance between the front mounting member 220 and the rear mounting member 260 so as to additionally stack the stator 110 and the rotor 121.
