Description

Technical Field

[0001] This utility model relates to the field of motor base technology, specifically a motor base with noise reduction function. Background Technology

[0002] During the motor operation, the motor will produce noise, and as the motor power increases, the noise will become louder and louder, affecting people's normal rest and work.

[0003] Chinese patent disclosure CN220457222U discloses a motor base with noise reduction function, including a receiving plate, an installation component fixedly mounted on one of the receiving plates, and insertion rods fixedly connected to the top of two connecting plates. This utility model provides a motor base with noise reduction function. Traditional motor bases with noise reduction function often lack functional complexity, requiring multiple screws for cumbersome, time-consuming, and labor-intensive installation of the motor. This device features an installation component where the motor to be installed is placed on top of the installation plate. Then, the servo motor is activated. The output shaft of the servo motor is keyway connected to two screws, each with a threaded sleeve on its outer wall. Driven by the screws, multiple insertion rods move in opposite directions, inserting into the motor body for fixation.

[0004] However, it still has the following drawbacks: the device uses the elastic force of the first and second springs to buffer and dampen the motor, but the motor fluctuates significantly during operation, causing the motor shaft to be extremely unstable and affecting the normal use of the motor. Therefore, we propose a motor base with noise reduction function to solve this problem. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5The present invention provides a technical solution: a motor base with noise reduction function, including a motor 1, a mounting device 2 is provided on the outside of the motor 1, and the mounting device 2 includes a shock-absorbing part 22;

[0025] The shock-absorbing part 22 includes a mounting frame 221, a first friction plate 220 and a second friction plate 201.

[0026] The screw 228 has a thread that penetrates the outer surface of the mounting frame 221 and extends into the interior of the mounting frame 221. The outer surface of the screw 228 is rotatably connected to the outer surface of the outer slider 203 through a bearing seat. The outer surface of the third spring 204 is fixedly connected to the outer surface of the slider 203. A limit groove is provided on the inner wall of the mounting frame 221. The outer surface of the slider 203 is slidably connected to the inner wall of the limit groove. The top surfaces of the two mounting plates 229 are fixedly connected to the bottom surfaces of the two inner sliders 203 respectively. The bottom surface of the fixed plate 202 is fixedly connected to the top surface of the sliding plate 222.

[0027] The friction frame 225 is slidably sleeved on the outer surface of the column 223, the slide plate 222 is fixedly sleeved on the outer surface of the friction frame 225, the bottom end of the second spring 224 is fixedly connected to the inner wall of the mounting frame 221, and the top end of the second spring 224 is fixedly connected to the bottom surface of the slide plate 222.

[0028] The bottom surface of the mounting frame 221 is fixedly connected to the top surface of the shock-absorbing pad 227. The outer surface of the bottom end of the shock-absorbing pad 227 is fixedly penetrated through the top surface of the base plate 226 and extends into the interior of the base plate 226. By setting the mounting frame 221, the slide plate 222, the column 223, the second spring 224, the friction frame 225, the base plate 226, the shock-absorbing pad 227, the screw 228, the mounting plate 229, the first friction plate 220, the second friction plate 201, the fixing plate 202, the slider 203, and the third spring 204, the motor 1 vibrates and drives the slide plate 222 to slide up and down. The spring 224 is used for buffering. At the same time, the elastic force of the second spring 204 causes the outer surface of the first friction plate 220 to rub against the outer surface of the second friction plate 201, which dampens the slide plate 222. The mechanical energy of the device vibration is converted into heat energy to dampen the device. The shock-absorbing pad 227 is used to dampen the motor 1 and the mounting frame 221.

[0029] A noise reduction part 21 is provided above the mounting frame 221;

[0030] The noise reduction unit 21 includes a limiting member 215, the outer surface of which slides through the top surface of the mounting shell 212 and extends to the bottom of the mounting shell 212. The noise reduction unit 21 also includes sound-absorbing cotton 211, mounting shell 212, slide rail 213 and first spring 214.

[0031] The top surface of the mounting frame 221 is provided with a sliding groove, the outer surface of the slide rail 213 is slidably connected to the inner wall of the sliding groove, the bottom surface of the mounting shell 212 is fixedly connected to the top surface of the slide rail 213, and the inner wall of the mounting shell 212 is fixedly connected to the outer surface of the sound-absorbing cotton 211. By setting the sound-absorbing cotton 211, the mounting shell 212 and the slide rail 213, the sound-absorbing cotton 211 absorbs the noise emitted by the motor 1.

[0032] The top surface of the mounting frame 221 has a slot, and the outer surface of the limiting member 215 extends into the slot. The top end of the first spring 214 is fixedly connected to the inner wall of the limiting member 215, and the bottom end of the first spring 214 is fixedly connected to the top surface of the mounting shell 212. By setting the first spring 214 and the limiting member 215, the tension of the first spring 214 is used to position the limiting member 215 on the mounting shell 212.

[0033] In use, rotating the screw 228 causes the outer slider 203 to move, adjusting the compression of the third spring 204 and the squeezing force between the first friction plate 220 and the second friction plate 201. When the motor 1 vibrates, it causes the mounting frame 221 and the sliding plate 222 to vibrate, resulting in relative displacement between the friction frame 225 and the column 223, and relative displacement between the first friction plate 220 and the second friction plate 201. This converts part of the mechanical energy of the device's vibration into heat energy, and the sound-absorbing cotton 211 absorbs the noise emitted by the motor 1.
