Description

Technical Field

[0001] The utility model relates to the technical field of curtains, in particular to a noise reduction curtain control motor. Background Art

[0002] Noise reduction curtain control motors are usually used to reduce the noise generated when the curtains are operated. Such motors may use some special designs or technologies to reduce friction and vibration, and may also be equipped with some sound insulation or vibration reduction devices to provide a quieter and more comfortable use experience.

[0003] After searching, a noise reduction curtain motor with announcement number CN219833899U includes a motor, the outer end cover of the motor is provided with a noise reduction cover, the inner circumference of the noise reduction cover is provided with a metal cylinder plate, and sound-absorbing thin felt and sound-absorbing filling layer are provided between the metal cylinder plate and the noise reduction cover from the inside to the outside. When assembling the device, first put the bottom end of the motor into the positioning sleeve, and after putting it in, fix the noise reduction cover on the curtain track. While fixing, the position of the motor can be positioned at the same time through the cooperation of the positioning sleeve and the installation sleeve. During use, the noise generated is transmitted into the sound-absorbing thin felt and the sound-absorbing filling layer through the through hole. Through the cooperation of the sound-absorbing thin felt and the sound-absorbing filling layer, most of the generated sound can be absorbed to complete the noise reduction operation. In addition, during the working process, the heat generated is first discharged into the porous sound-absorbing filling layer through the through hole, and then the heat is discharged through the heat dissipation fins, which can ensure the noise reduction while meeting the overall heat dissipation effect.

[0004] Based on the above patent, the background technology thereof mentions that a soundproof cover is installed on the outside of the motor. However, since a soundproof layer is laid inside the soundproof cover, it will affect the overall heat dissipation operation. In addition, during the installation, the motor needs to be installed first and then the soundproof cover, which will make the overall disassembly and assembly complicated. In this regard, in response to this technical problem, the present application proposes a noise reduction type curtain control motor. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-4The utility model provides an embodiment: a noise reduction curtain control motor, including a curtain track 1, an AC motor 4 is fixedly connected to the left side of the bottom end of the curtain track 1, and the AC motor 4 is used as a driving source of the curtain track 1 to control the opening and closing of the curtain, and the bottom end of the curtain track 1 is fixedly connected to an annular baffle 5 near the outside of the AC motor 4. The annular baffle 5 is made of cork board material and has good sound insulation material. An annular groove 13 is opened at the top of the connecting plate 8 corresponding to the bottom of the annular baffle 5. During installation, the annular baffle 5 is buckled in the annular groove 13 to form a closed state. The inner walls of the middle parts of the left and right ends of the connecting plate 8 are both provided with limiting grooves 14. A protective cover 2 3 is fixedly connected to the inner side of the bottom end of the connecting plate 8, and a protective cover 1 2 is fixedly connected to the bottom end of the connecting plate 8 near the outside of the protective cover 2 3. A plurality of air dispersion holes 12 are opened on the outer side of the bottom end of the protective cover 1 2.

[0026] A damper 16 is fixedly connected to the inner wall of the bottom end of the protective cover 23, and a tray 18 is fixedly connected to the top of the damper 16. The tray 18 is connected to the inner wall of the protective cover 23 through a first spring 17. One end of the first spring 17 is fixedly connected to the bottom end of the tray 18 near the outer side of the damper 16, and the other end of the first spring 17 is fixedly connected to the bottom end of the protective cover 23 near the outer inner wall of the damper 16. The tray 18 is placed at the bottom end of the AC motor 4. When the AC motor 4 is in use, a certain vibration will be generated. Through the cooperation of the damper 16 and the first spring 17, the vibration of the AC motor 4 is buffered, thereby reducing the noise generated by the vibration of the AC motor 4.

[0027] The shape of the bottom end of the annular baffle 5 is consistent with the shape of the inner wall of the annular groove 13. A plurality of vents 9 are provided on the upper side of the outer wall of the protective cover 2 3. The inner walls of the vents 9 are fixedly connected with sound-absorbing cotton 15. The outer walls of the protective cover 2 3 and the inner walls of the protective cover 1 2 are fixedly connected with a plurality of sound insulation rings 10 in turn. The outer walls of the sound insulation rings 10 are provided with sound insulation coating 11. The sound insulation coating 11 is a mixture of glass fiber, polystyrene particles and acoustic resin. The heat generated by the AC motor 4 during use will diffuse outward through the vents 9. At the same time, the noise will pass through the sound-absorbing cotton 15 on the inner wall of the vents 9. The noise will be initially absorbed by the material of the sound-absorbing cotton 15, and then the heat will be discharged to the outside along the direction of the air dispersion hole 12, and the noise will be completely absorbed after passing through the sound insulation coating 11 on the surface of the sound insulation ring 10 in turn.

[0028] The chute block 6 is fixedly connected to the middle part of the left and right ends of the annular baffle plate 5, and the inner wall of the chute block 6 is slidably connected with a slider 19, and the slider 19 is connected to the inner wall of the chute block 6 by a second spring 20. The bottom end of the slider 19 is fixedly connected with a clamping plate 7, and the upper side of the outer wall of the clamping plate 7 is slidably connected to the inner wall of the through groove at the bottom end of the chute block 6. The inner wall of the groove at the opposite end of the clamping plate 7 is embedded in the opposite end of the inner wall of the limiting groove 14, and the opposite end of the second spring 20 is fixedly connected to the opposite end of the slider 19. The opposite end of the second spring 20 is fixedly connected to the inner wall of the chute block 6. Before repairing and replacing the AC motor 4, it is only necessary to pull the clamping plates 7 on both sides inward to completely place the bottom end of the clamping plate 7 on the lower side of the inner wall of the limiting groove 14, so that the limiting relationship between the clamping plate 7 and the connecting plate 8 is released, and then the protective cover 2 is removed from the outside of the AC motor 4 together with the connecting plate 8, so as to repair and replace the AC motor 4.

[0029] Working principle: First, the tray 18 is placed at the bottom of the AC motor 4. When the AC motor 4 is in use, it will generate a certain vibration. Through the cooperation of the damper 16 and the first spring 17, the vibration of the AC motor 4 is buffered, thereby reducing the noise generated by the vibration of the AC motor 4, and the heat generated by the AC motor 4 during use will diffuse outward through the vent 9. At the same time, the noise will pass through the sound-absorbing cotton 15 on the inner wall of the vent 9. Under the action of the material of the sound-absorbing cotton 15, the noise will be initially absorbed, and then the heat will be discharged to the outside along the direction of the air vent 12, and the noise will be completely absorbed after passing through the sound insulation coating 11 on the surface of the sound insulation ring 10 in turn. Before repairing and replacing the AC motor 4, you only need to pull the two side clamping plates 7 inward to completely place the bottom end of the clamping plate 7 on the lower side of the inner wall of the limiting groove 14, so that the limiting relationship between the clamping plate 7 and the connecting plate 8 is released, and then the protective cover 2 together with the connecting plate 8 is removed from the outside of the AC motor 4, so that the AC motor 4 can be repaired and replaced.
