[0012] (1) The low-noise motor based on electromagnetic excitation force simulation described in the present invention uses a tool to rotate the resistance mechanism, thereby limiting the main mechanism, thereby facilitating the limiting of the main mechanism and also preventing it from vibrating at a large amplitude during operation, that is: the operator can put the support block into the mounting frame, and a rubber pad is fixed in the mounting frame. When the motor body is started, the setting of the rubber pad can reduce the contact between the support block and the mounting frame; a screw rod is rotatably connected in the mounting frame, and a slide rod is fixed in the mounting frame. A resistance plate is threadedly connected to the screw rod, and the screw rod can be rotated by a tool to limit the resistance plate between the screw rod and the slide rod.

The provision of the balls can also reduce the friction area between the mounting frame and the bracket. The bracket is fixedly mounted on the fixing plate. After the mounting frame is placed, the operator can fix the motor body. Due to the fixed connection between the card plate and the mounting frame, a gasket is fixedly mounted on the bracket. When the mounting frame is engaged with the inside of the bracket, it contacts the gasket, thereby facilitating the reduction of the sound generated by the vibration of the motor body.

[0014] (3) The low-noise motor based on electromagnetic excitation force simulation described in the present invention uses a tool to rotate the limiting mechanism, so that it can be engaged in the fixing mechanism when sliding inside the supporting mechanism, so that it is convenient to limit the fixing mechanism and prevent it from loosening. That is, when the mounting frame needs to be fixed, the operator can use the tool to rotate the screw rod.

[0031] Specifically, the support mechanism 1 includes a bracket 102, the mounting frame 201 is snap-connected with the bracket 102, a gasket 103 is fixedly connected to the bracket 102, the gasket 103 is in conflict with the mounting frame 201, the bracket 102 is fixedly connected to the fixing plate 101, the support mechanism 1 also includes a slot 104, two slots 104 are symmetrically provided on the bracket 102, a card plate 202 is snap-connected at the slot 104, two groups of balls 105 are rotated on the bracket 102, the balls 105 are rollingly connected with the card plate 202, the fixing mechanism 2 is snapped into the support mechanism 1, and then the main mechanism 3 is installed on the fixing mechanism 2, so as to facilitate the support of the main mechanism 3, that is, the operator inserts the card plate 202 into the bracket 10 2 is provided with a card slot 104, and two groups of balls 105 are rotated in the bracket 102. When the card plate 202 slides in the card slot 104, the balls 105 can be driven to rotate, so that it is convenient to place the mounting frame 201 and it is also convenient for operators to disassemble it. The provision of the balls 105 can also reduce the friction area between the mounting frame 201 and the bracket 102. The bracket 102 is fixedly mounted on the fixing plate 101. After the mounting frame 201 is placed, it is convenient for operators to fix the motor body 301; due to the fixed connection between the card plate 202 and the mounting frame 201, a gasket 103 is fixedly installed on the bracket 102. When the mounting frame 201 is engaged with the inside of the bracket 102, it contacts the gasket 103, so as to reduce the sound generated when the motor body 301 vibrates.

[0032] Specifically, the limiting mechanism 4 includes a screw rod 401, two screw rods 401 are symmetrically connected to the bracket 102 for rotation, a guide wheel 404 is fixedly installed on the screw rod 401, a belt 405 is wound around the guide wheel 404, a slide plate 406 is threadedly connected to the screw rod 401, and a plurality of clamping blocks 403 are fixedly installed on the slide plate 406 at equal intervals, the limiting mechanism 4 also includes an anti-skid pad 402, an anti-skid pad 402 is fixedly connected to the clamping block 403, and the anti-skid pad 402 is in conflict with the clamping plate 202. The limiting mechanism 4 is rotated by a tool, so that it is engaged with the fixing mechanism 2 when sliding inside the support mechanism 1, thereby facilitating the limiting mechanism 2 to be limited and preventing it from loosening, that is, when the mounting frame 201 needs to be fixed, the operator can use a tool to rotate the screw rod 401, and the bracket 102 is rotated to There are two screw rods 401 in a dynamic connection, and guide wheels 404 are fixedly installed on the screw rods 401, and belts 405 are wound around the guide wheels 404. When one screw rod 401 rotates inside the bracket 102, it can drive one guide wheel 404 to rotate, and then the belt 405 drives the other guide wheel 404 to rotate. Since a slide plate 406 is threadedly connected to the screw rod 401, when the two screw rods 401 start to rotate, the slide plate 406 can slide inside the bracket 102 along the screw rod 401, and a number of blocks 403 are fixedly installed on the slide plate 406 at equal intervals, and anti-skid pads 402 are bonded to the blocks 403.

[0033] When the present invention is in use, first, the operator can put the support block 302 into the mounting frame 201, and the rubber pad 303 is fixed in the mounting frame 201.

The screw rod 501 is threadedly connected with a plate 503. The screw rod 501 is rotated by a tool, so that the plate 503 can slide along the mounting frame 201 under the limiting action of the screw rod 501 and the slide rod 502. Since the two ends of the plate 503 are arranged in an inclined surface, when sliding, the plate 503 hits the rolling bearing rotating on the rod 507. The roller 504 contacts with the wheel 504, so that the roller 504 starts to rotate along the inclined surface of the supporting plate 503. A connecting shaft 505 is fixedly installed on the supporting rod 507, and a torsion spring 506 is sleeved on the connecting shaft 505. When the roller 504 rotates, it can drive the supporting rod 507 to rotate, so that the connecting shaft 505 and the torsion spring 506 are deformed when the supporting rod 507 rotates. The supporting rod 507 rotates in the mounting frame 201 and is stuck in the empty groove 304 provided in the support block 302. When the supporting rod 507 contacts the inner wall of the support block 302, the end of the supporting rod 507 can limit the support block 302, so that the support block 302 can be fixed conveniently and the support block 302 can also better support the motor body 301.

[0034] The operator inserts the card plate 202 into the card slot 104 provided in the bracket 102. Two groups of balls 105 are arranged in the bracket 102 to cooperate and rotate. When the card plate 202 slides in the card slot 104, the balls 105 can be driven to rotate, so that it is convenient for the operator to place the mounting frame 201 and also convenient for the operator to disassemble it. The provision of the balls 105 can also reduce the friction area between the mounting frame 201 and the bracket 102. The bracket 102 is fixedly mounted on the fixing plate 101. After the mounting frame 201 is placed, it is convenient for the operator to fix the motor body 301. Since the card plate 202 and the mounting frame 201 are fixedly connected, a gasket 103 is fixedly mounted on the bracket 102. When the mounting frame 201 is engaged with the inside of the bracket 102, it contacts with the gasket 103, so as to reduce the sound generated when the motor body 301 vibrates.

[0035] When the mounting frame 201 needs to be fixed, the operator can use a tool to rotate the screw rod 401. Two screw rods 401 are rotatably connected in the bracket 102, and guide wheels 404 are fixedly installed on the screw rods 401. Belts 405 are wound around the guide wheels 404. When one screw rod 401 rotates inside the bracket 102, it can drive one guide wheel 404 to rotate, and then the belt 405 drives another guide wheel 404 to rotate. Since the screw rod 401 is threadedly connected with a slide plate 406, When the two screw rods 401 start to rotate, the slide plate 406 can slide along the screw rods 401 inside the bracket 102. Several blocks 403 are fixedly installed on the slide plate 406 at equal intervals. The anti-skid pads 402 are adhered to the blocks 403. The slide plate 406 drives the blocks 403 to slide, so that the blocks 403 can be engaged with the limiting grooves 203. The anti-skid pads 402 contact the inner wall of the card plate 202, thereby facilitating the limiting of the card plate 202 and reducing the vibration of the mounting frame 201.
