[0009] Furthermore, there are multiple elastic shock-absorbing pads, all of which are in a strip-shaped structure. All of the elastic shock-absorbing pads are distributed at intervals along the circumference of the motor body shell and are extended in the length direction of the motor body shell.
[0010] The above arrangement can form an effective buffer to reduce vibration noise when vibration occurs, while reducing the material cost of the elastic shock-absorbing pad, reducing a certain weight of the motor body, and reducing power consumption to a certain extent.
[0011] Furthermore, all elastic shock-absorbing pads are evenly distributed along the circumference of the motor body shell.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0025] In the description of the present utility model, it should be noted that the terms "upper", "lower", "left", "right", "front", "back", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.
[0026] The present embodiment provides a motor structure for vibration reduction and noise reduction, including a motor body 1, on the outer shell of which is fixed at least one elastic shock-absorbing pad 11. When the motor body 1 is installed in an installation cavity of an external device, the outer surface of the elastic shock-absorbing pad 11 abuts against the inner wall of the installation cavity.
[0027] Specifically, the vibration noise of the motor body 1 is mainly caused by the collision between the motor body 1 and the installation cavity of the external device during vibration. The elastic shock-absorbing pad 11 can be against the inner wall of the installation cavity of the external device due to its elasticity. When vibration occurs, the elastic shock-absorbing pad 11 can form an effective buffer between the installation cavity, so that the vibration noise of the motor body is reduced. The back of the elastic shock-absorbing pad 11 can be bonded to the outer shell of the motor body 1 by gluing. The thickness of the elastic shock-absorbing pad 11 is between 0.5mm and 1mm. An elastic shock-absorbing pad 11 that is too thin may have ineffective shock absorption, and an elastic shock-absorbing pad 11 that is too thick may not be effectively installed in the installation cavity.
[0028] In the preferred embodiment of the present utility model, the elastic shock-absorbing pad 11 is in a cylindrical structure and is sleeved on the outer shell of the motor body 1 .
[0029] Specifically, the elastic shock-absorbing pad 11 of the cylindrical structure can be wrapped 360° on the outer shell of the motor body 1. The premise of this embodiment is that the shape of the motor body 1 is a long strip structure, such as the attached Figure 1 To Attachment Figure 3 The cylindrical structure in the embodiment can be fixed by gluing after being installed. In this embodiment, since the elastic shock-absorbing pad 11 completely covers the outer shell of the motor body 1, this embodiment can be applied to the installation cavity of all external devices and has good adaptability.
[0030] In a preferred embodiment of the present invention, there are multiple elastic shock-absorbing pads 11, all of which are strip-shaped structures. All elastic shock-absorbing pads 11 are distributed at intervals along the circumference of the motor body 1 shell and extend in the length direction of the motor body 1 shell.
[0031] Specifically, as attached Figure 2As shown, when vibration occurs, the elastic shock-absorbing pads 11 of each strip structure form an effective buffer for the motor body 1 to reduce vibration noise. At the same time, since they are arranged at intervals from each other, the material cost of the elastic shock-absorbing pads 11 can be reduced, the weight of the motor body 1 can be reduced, and the power consumption can be reduced to a certain extent. In this embodiment, the elastic shock-absorbing pads 11 of each strip structure can be fixed to the outer shell of the motor body 1 by bonding.
[0032] In the preferred embodiment of the present utility model, as shown in the attached Figure 2 As shown, all elastic shock-absorbing pads 11 are evenly distributed along the circumference of the outer shell of the motor body 1, so that the outer shell of the motor body 1 can be effectively buffered at each position of 360° in the circumference.
[0033] In a preferred embodiment of the present invention, there are multiple elastic shock-absorbing pads 11, all of which are annular in structure. All elastic shock-absorbing pads 11 are sleeved on the circumference of the motor body 1 shell and are spaced apart along the length direction of the motor body 1 shell.
[0034] Specifically, as attached Figure 3 As shown, when vibration occurs, the elastic shock-absorbing pads 11 of each annular structure effectively buffer the motor body 1 to reduce vibration noise. At the same time, since they are arranged at intervals from each other, the material cost of the elastic shock-absorbing pads 11 can be reduced, the weight of the motor body 1 can be reduced, and the power consumption can be reduced to a certain extent. In this embodiment, the elastic shock-absorbing pads 11 of each annular structure can be fixed to the outer shell of the motor body 1 by sleeve or winding, and then fixed by gluing. The premise of this embodiment is that the shape of the motor body 1 is a long strip structure, such as the attached Figure 1 To Attachment Figure 3 The cylindrical structure in.
[0035] In the preferred embodiment of the present utility model, as shown in the attached Figure 3 As shown, all elastic shock-absorbing pads 11 are evenly distributed along the length direction of the shell of the motor body 1, so that the shell of the motor body 1 can be effectively buffered at each position in the length direction.
[0036] In a preferred embodiment of the present invention, the elastic shock-absorbing pad 11 is made of silica gel or foam.
[0037] Specifically, the material cost of the above-mentioned elastic shock-absorbing pad 11 is relatively low, and it can form an effective buffer when vibration occurs, thereby reducing the vibration noise of the motor body 1. The material of the elastic shock-absorbing pad 11 of the utility model is not limited to this, and it can also be other existing elastic materials. Technical personnel in this field can flexibly choose according to the existing technology.
[0038] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
