[0023] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0024] In the present utility model, unless otherwise clearly specified and limited, terms such as "installed", "connected", "connected to", "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] In the present utility model, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0026] Such as Figure 1-7As shown in the figure, a driving device for an electric curtain includes a housing 1. Inside the housing 1, there are two motors 2 arranged side by side and at least one control board 3. The two motors 2 can work independently. The motor 2 has opposite output ends and tail ends. The output ends of the two motors 2 are connected with a fixing frame 4 and a first shock absorber 5 from the inside to the outside. The tail ends of the two motors 2 are connected with a second shock absorber 6.

[0027] In the utility model, by arranging the first shock absorber 5 and the second shock absorber 6 at both ends of the two motors 2, the motors 2 are not in direct contact with the housing 1. The first shock absorber 5 and the second shock absorber 6 can filter the vibrations generated by the motors 2, playing a role in reducing vibration and noise. In addition, the fixing frame 4 in the first shock absorber 5 can fix the two motors 2. The fixing frame 4 fixedly connects the two motors 2 together and can protect the first shock absorber 5, prolonging the service life of the first shock absorber 5. Since the output end of the motor 2 has a large torque, and the output ends of the two motors 2 have an even larger torque, the first shock absorber 5 is easily damaged after long-term use, such as being deformed, which will affect the installation position of the motor 2 to shift, thus affecting the operation of the driving device. The setting of the fixing frame 4 can fix the two motors 2 and also protect the first shock absorber 5 to maintain its shape, enabling the motor 2 to output power normally for a long time.

[0028] Among them, the fixing frame 4 is provided with a first channel 4.1 and a second channel 4.2 for connecting the motor 2. The first channel 4.1 and the second channel 4.2 are symmetrically arranged. The first channel 4.1 and the second channel 4.2 can respectively accommodate the two motors 2 for installation, thus playing a role in fixing the motors 2. The first shock absorber 5 is provided with a cavity 5.1 for the fixing frame 4 to be embedded. The fixing frame 4 is embedded in the first shock absorber 5, playing a role in supporting and protecting the first shock absorber 5 to prevent the first shock absorber 5 from being deformed after long-term use. The second shock absorber 6 is provided with a first connection groove 6.1 and a second connection groove 6.2 for connecting the motor 2, which can avoid the contact between the motor 2 and the housing 1 and is relatively convenient for assembly.

[0029] Among them, the fixing frame 4 is provided with screw holes 4.3. The screw holes 4.3 communicate with the corresponding first channel 4.1 and second channel 4.2. The motor 2 is provided with mounting holes 2.1 corresponding to the screw holes 4.3. By screwing screws into the screw holes 4.3 and the mounting holes 2.1, the fixing frame 4 is fixedly connected to the two motors 2.

[0030] Among them, the housing 1 includes a detachable front cover 1.1 and a rear cover 1.2, which is convenient for disassembly and assembly. The end face of the first shock absorber 5 away from the second shock absorber 6 abuts against the front cover 1.1. A filling block 7 is provided between the second shock absorber 6 and the rear cover 1.2. One end of the filling block 7 abuts against the rear cover 1.2, and the other end abuts against the end face of the second shock absorber 6 away from the first shock absorber 5, ensuring that the motor 2 does not contact the housing 1. The setting of the filling block 7 plays an axial limiting role to avoid axial movement.

[0031] Among them, an output shaft 2.2 is connected to the output end of the motor 2. A through hole 5.2 for the output shaft 2.2 to pass through is provided on the first shock absorber 5. A round hole 1.3 for the output shaft 2.2 to pass through is provided on the front cover 1.1. The number of the through holes 5.2 and the round holes 1.3 is the same as the number of the output shafts 2.2.

[0032] Among them, the first shock absorber 5 and the second shock absorber 6 are both made of flexible materials such as rubber and silica gel, and the fixing frame 4 is made of hard materials such as plastic and metal.

[0033] Among them, the control board 3 is installed at the tail end of the housing 1 close to the motor 2. The control board 3 is perpendicular to the two motors 2 and is electrically connected to the two motors 2, with a smaller overall volume and a shorter length.

[0034] Among them, the number of the control boards 3 is two. The two control boards 3 are arranged in parallel and connected by pin headers or flexible cables.

[0035] The materials, reagents and experimental equipment involved in the embodiments of the present utility model are all commercially available products that conform to the field of curtain driving devices unless otherwise specified.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
