Electric curtains can realize the automatic opening and closing of the curtain cloth, and even the dimming of the curtain cloth, liberating the hands of the user. For a conventional electric opening and closing curtain, the motor is installed outside the track. For an electric louver curtain, the motor is installed inside the track, and it drives a rope winder, etc. to work to realize the electric lifting function of the louver curtain;

[0003] During the operation of the motor, vibration will be generated, and damping pads need to be installed at both ends of the motor to reduce the influence caused by electric vibration. In the prior art, polygonal convex shells extend from both ends of the motor, and the damping pads are sleeved on the convex shells and are detachably connected to the convex shells, but this structure will make the occupied space of the motor and the damping pads in the length direction large. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a motor damping pad and an electric curtain thereof, which are used to reduce the occupied space of the motor and the damping pads in the length direction.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: A motor damping pad includes a pad body, and an accommodation cavity is formed in the pad body. The accommodation cavity wraps a corner of the motor housing, and an avoidance hole is opened on one side of the pad body perpendicular to the motor output axis.

[0018] The present utility model will be further described in detail below with reference to the drawings and embodiments. The same components are denoted by the same reference signs. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0019] Refer to Figures 1 to 2As shown in the figure, a motor vibration damping pad according to this embodiment includes a pad body 1. An accommodation cavity 11 is formed in the pad body 1, and the accommodation cavity 11 wraps around a corner of the motor housing. An avoidance hole 12 is formed on one side of the pad body 1 perpendicular to the motor output axis. The avoidance hole 12 can avoid the output end of the motor. The output end is generally a hexagonal groove and is connected to a hexagonal bar. Therefore, interference with the hexagonal bar can be avoided. Under the action of multiple vibration damping pads, the motor does not directly contact the outer frame 7 of the electric curtain, thus having little impact on the vibration of the outer frame 7.

[0020] Among them, the bottom of the vibration damping pad extends below the motor, playing a role in supporting the motor, thereby achieving a vibration damping effect.

[0021] The convex shells extending from both ends of the motor can be omitted. In the prior art, the convex shells are detachably connected to the vibration damping pads, usually achieved by means of buckles. Due to the need to set buckles, the convex shells need to have a certain length. Therefore, by reducing the setting of the convex shells, the space occupied by the motor in the length direction only increases by the thickness of the vibration damping pad. In addition, the thickness of the vibration damping pad that does not require buckles can also be reduced accordingly, thereby reducing the space occupied by the motor and the vibration damping pad in the length direction.

[0022] The side of the vibration damping pad fits with the motor, having a better fit with the motor and wrapping around a corner of the motor housing.

[0023] Four vibration damping pads can be set. When the motor is placed flat, the four corners of the motor located below are all wrapped, better forming vibration damping.

[0024] Refer to Figure 1 and Figure 2 As shown in the figure, a positioning strip 2 is formed on one side of the pad body 1 and cooperates with a positioning groove 3 formed on the motor housing. The motor housing includes a housing and two end covers. Among them, both end covers are detachably connected to the housing. The positioning groove 3 can be formed on the housing or on the end covers.

[0025] Preferably, the positioning groove 3 is formed on the end cover and is formed from bottom to top, that is, the opening of the positioning groove 3 faces downward, so as to facilitate the installation of the pad body 1 from bottom to top. The positioning strip 2 is inserted into the positioning groove 3 from bottom to top to prevent the pad body 1 from detaching, playing a limiting role.

[0026] Refer to Figure 1 and Figure 2 As shown in the figure, a limiting groove 4 with an upward opening is formed on one side of the pad body 1 and cooperates with a protrusion 5 formed on the motor housing. Among them, the protrusion 5 can be formed on the housing or on the end covers.

[0027] Preferably, the protrusion 5 is formed on the end cover. When installing the pad body 1, as the limiting groove 4 moves, the protrusion 5 enters the limiting groove 4.

[0028] Refer toFigure 1 As shown, the bottom end of the limiting groove 4 communicates with a clamping groove 6, and a bulge is formed between the clamping groove 6 and the limiting groove 4. As the limiting groove 4 moves, the protrusion 5 will cross the bulge and enter the clamping groove 6, and a certain deformation force needs to be overcome;

[0029] The setting of the bulge and the clamping groove 6 plays an anti - detachment role. Before installing the motor, when moving the motor, the gasket 1 will not become detached from the motor.

[0030] Refer to Figure 1 、 Figure 3 As shown, the gaskets 1 are grouped in twos, and the two gaskets 1 within the same group are integrally formed with opposite orientations. The two avoidance holes 12 communicate with each other. The two integrally formed gaskets 1 can simultaneously wrap the two corners of the motor housing, and these two corners are located below the same end of the motor housing;

[0031] The communication of the two avoidance holes 12 forms at least an arc segment to avoid the output end of the motor;

[0032] Preferably, after the two avoidance holes 12 communicate, they form a semi - circle, and the opening of this semi - circle extends upward.

[0033] Refer to Figure 1 As shown, the gasket 1 includes a bottom plate 13, a first side plate 14 and a second side plate 15. The first side plate 14 and the second side plate 15 are perpendicular to each other, and both the first side plate 14 and the second side plate 15 are perpendicular to the bottom plate 13. The first side plate 14 and the second side plate 15 are both in contact with the motor housing. Among them, the positioning strip 2 can be arranged on the first side plate 14 or the second side plate 15. Of course, the limiting groove 4 can also be arranged on the first side plate 14 or the second side plate 15. The positioning strip 2 and the limiting groove 4 can be on the same side or on adjacent sides;

[0034] Preferably, the limiting groove 4 and the positioning groove 3 are on adjacent sides.

[0035] The material of the gasket 1 is one of rubber, silica gel, TPE or silicone rubber. Preferably, the material of the gasket 1 is silicone rubber.

[0036] Refer to Figure 3 As shown, an electric curtain includes an outer frame 7 and the above - mentioned motor vibration damping pad. Horizontal bars 71 are formed on the inner walls of the two opposite sides of the outer frame 7. The horizontal bars 71 abut against the top of the gasket 1, and the horizontal bars 71 cooperate with the bottom of the outer frame 7 to play a role in limiting the gasket 1 in the vertical direction;

[0037] Among them, horizontal convex strips are also formed on the two opposite inner walls of the outer frame 7. The horizontal convex strips abut against the side of the gasket 1, and this side is the side parallel to the central axis of the motor output end, playing a positioning role.

[0038] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
