It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model.

[0046] Referring to Figure 1 and Figure 2 , an electric curtain driving device with a built-in power supply includes a housing 1, a motor 2, a power supply 3, a reduction mechanism 4 and a driving mechanism 5. The motor 2, the power supply 3 and the reduction mechanism 4 are respectively arranged in the housing 1. The motor 2 is electrically connected to the power supply 3, and the reduction mechanism 4 is connected to the motor 2. One end of the driving mechanism 5 is arranged in the housing 1 and connected to the reduction mechanism 4, and the other end extends out of the housing 1. The end of the driving mechanism 5 extending out of the housing 1 is used to connect the curtain, so that the motor 2 can drive the driving mechanism 5 to work through the reduction mechanism 4, so as to drive the curtain to open and close.

[0047] In this embodiment, the power supply 3 can independently supply power to the motor 2, and both the power supply 3 and the motor 2 are arranged inside the housing 1, so that no external wires are required to supply power to the motor 2 when installing the driving device, which is beneficial to simplifying the installation steps and facilitating the installation of the electric curtain.

[0048] Referring to Figure 1 and Figure 2 , the housing 1 includes a first housing part 11, a second housing part 12, a third housing part 13, a fourth housing part 14 and a fifth housing part 15. Among them, the second housing part 12 is snap-connected to the first housing part 11, the third housing part 13 is snap-connected to the fourth housing part 14 and the second housing part 12 respectively, and the fifth housing part 15 is snap-connected to the fourth housing part 14 and the second housing part 12 respectively.

[0049] A closed installation cavity 16 is formed between the first housing part 11, the second housing part 12, the third housing part 13, the fourth housing part 14 and the fifth housing part 15, so as to facilitate the installation of the motor 2, the power supply 3, the reduction mechanism 4 and the driving mechanism 5 in the installation cavity 16. In this embodiment, the housing 1 adopts a split design, which facilitates the assembly and maintenance work.

[0050] Referring to Figure 3 and Figure 4 , in this embodiment, the fourth housing part 14 is integrally designed in a Z shape, and a hook 141 is fixedly connected to the fourth housing part 14. Referring to Figure 5 , a limiting member 142 is slidably arranged on the fourth housing part 14, a convex block 143 is fixedly connected to one side of the limiting member 142, and an elastic member 144 is arranged between the other side of the limiting member 142 and the fourth housing part 14. In this embodiment, the elastic member 144 is a spring.

[0051] Referring to Figure 3 and Figure 5 , a clamping groove 151 is formed at one end of the fifth housing part 15, and a limiting groove 152 is formed at the other end of the fifth housing part 15. When the fourth housing part 14 is connected to the fifth housing part 15, one end of the fourth housing part 14 extends below the fifth housing part 15. At this time, the hook 141 is inserted into the clamping groove 151 to limit the fifth housing part 15 from moving horizontally, and the elastic member 144 pushes the limiting member 142 to slide and be inserted into the limiting groove 152, and the convex block 143 abuts against the outer surface of the fifth housing part 15 and extends outside the second housing part 12 (referring to Figure 2 ), so that the limiting member 142 and the convex block 143 can jointly clamp the fifth housing part 15 to limit the fifth housing part 15 from moving vertically, thereby facilitating the connection and fixation of the fifth housing part 15 and the fourth housing part 14, which is beneficial to enhancing the overall structural strength and further improving the compactness and aesthetics of the entire device.

[0052] When it is necessary to separate the fifth housing part 15 from the fourth housing part 14, push the convex block 143 to move in the direction close to the fourth housing part 14. The convex block 143 drives the limiting member 142 to move, so that the limiting member 142 disengages from the limiting groove 152. Then move the fifth housing part 15 in the vertical direction to make the hook 141 disengage from the card slot 151, so as to facilitate the separation of the fifth housing part 15 and the fourth housing part 14.

[0053] Refer to Figure 1 and Figure 2 , it should be noted that in the embodiments of the present application, how the first housing part 11, the second housing part 12, the third housing part 13 and the fourth housing part 14 are specifically clamped can be adaptively designed, which belongs to the conventional technical means for those skilled in the art. Therefore, it will not be elaborated too much in the embodiments of the present application.

The first linkage gear group 42 and the second linkage gear group 43 are respectively arranged in the reduction gearbox 41.

[0055] Refer to Figure 6 , the first linkage gear group 42 is fixedly connected to the output end of the motor 2 and is responsible for transmitting the rotational power of the motor 2. The second linkage gear group 43 is respectively connected to the first linkage gear group 42 and the driving mechanism 5, playing the role of a "bridge" to smoothly transmit the power from the first linkage gear group 42 to the driving mechanism 5. Through such a design, the motor 2 can efficiently drive the driving mechanism 5 to work through the first linkage gear group 42 and the second linkage gear group 43.

[0056] Refer to Figure 2 and Figure 6 , the first linkage gear group 42 includes a driving gear 421, a transmission shaft 422, a first transmission gear 423 and a second transmission gear 424. The output shaft of the motor 2 extends into the reduction gearbox 41, and the driving gear 421 is coaxially connected to the output shaft of the motor 2, so that the rotational power of the motor 2 can be directly transmitted to the driving gear 421.

[0057] The transmission shaft 422 is rotatably connected in the reduction gearbox 41, and the first transmission gear 423 and the second transmission gear 424 are respectively coaxially connected to the transmission shaft 422, so that the transmission shaft 422 can provide stable support for the first transmission gear 423 and the second transmission gear 424. And the first transmission gear 423 meshes with the driving gear 421, so as to facilitate the transmission of the power of the motor 2 to the first transmission gear 423 and the second transmission gear 424.

[0058] The second linkage gear set 43 includes a linkage shaft 431, a first linkage gear 432, a second linkage gear 433, and a third linkage gear 434.

The third linkage gear 434 is rotatably connected within the reduction gearbox 41 and is connected to the drive mechanism 5, and the third linkage gear 434 meshes with the second linkage gear 433.

[0059] When the motor 2 operates, the motor 2 can drive the driving gear 421 to rotate. The driving gear 421 can drive the first transmission gear 423 to rotate. The first transmission gear 423 can drive the second transmission gear 424 to rotate through the transmission shaft 422, such that the second transmission gear 424 drives the first linkage gear 432 to rotate. The first linkage gear 432 drives the second linkage gear 433 to rotate through the linkage shaft 431. The second linkage gear 433 drives the third linkage gear 434 to rotate, thereby facilitating the third linkage gear 434 to drive the drive mechanism 5 to operate.

[0060] Refer to Figure 6 As shown, the drive mechanism 5 includes a linkage assembly 51 and a drive assembly 52. The linkage assembly 51 includes a transmission member 511 and a detection block 512. The transmission member 511 is rotatably connected within the housing 1 and is coaxially connected to the third linkage gear 434, such that the rotation of the third linkage gear 434 can drive the transmission member 511 to rotate.

[0061] The drive assembly 52 includes a pulley 521 and a belt 522 wound around the pulley 521. The transmission member 511 is coaxially connected to the pulley 521. In this embodiment, the belt 522 is used to connect to the curtain. When the transmission member 511 rotates, the transmission member 511 will drive the pulley 521 to rotate. The pulley 521 can drive the belt 522 to rotate, thereby facilitating driving the opening and closing of the curtain through the belt 522.

[0062] Refer to Figure 2 and Figure 6 As shown, a plurality of detection blocks 512 are provided. The plurality of detection blocks 512 are evenly distributed along the circumferential direction of the transmission member 511. And a photoelectric sensor 17 is provided within the installation cavity 16. The photoelectric sensor 17 is disposed close to the detection block 512. Thus, when the transmission member 511 rotates, the detection blocks 512 will sequentially pass by the photoelectric sensor 17, so as to facilitate using the photoelectric sensor 17 to detect the number of rotation turns of the transmission member 511, and further facilitate accurately controlling the rotation angle and speed of the motor 2 to achieve accurate control of the opening and closing degree of the curtain.

[0065] Referring to Figure 7 and Figure 8 , a socket 19 is arranged inside the second housing part 12. When the socket 19 needs to be installed, the socket 19 is inserted horizontally into the clamping groove 182 so that the socket 19 fits against the inner wall of the clamping groove 182, facilitating the clamping seat 181 to limit the socket 19. At this time, one end of the socket 19 extends into the insertion groove 183 and abuts against the clamping block 184, so that the clamping block 184 limits the socket 19, making it difficult for the socket 19 to move away from the clamping groove 182, thus facilitating the stable installation of the socket 19 at the designated position.

[0066] Referring to Figure 2 and Figure 8 , in this embodiment, the socket 19 is electrically connected to the power supply 3, and a relief groove 111 is formed on the first housing part 11, and one end of the socket 19 extends out of the relief groove 111, facilitating charging the power supply 3 through the socket 19.

[0068] The implementation principle of an electric curtain driving device with a built-in power supply in an embodiment of the present application is as follows: When it is necessary to control the opening and closing of the curtain, first start the motor 2. The motor 2 drives the driving gear 421 to rotate. The driving gear 421 drives the first transmission gear 423 to rotate. The first transmission gear 423 drives the second transmission gear 424 to rotate through the transmission shaft 422. The second transmission gear 424 drives the first linkage gear 432 to rotate. The first linkage gear 432 drives the second linkage gear 433 to rotate through the linkage shaft 431. The second linkage gear 433 drives the third linkage gear 434 to rotate. The third linkage gear 434 drives the pulley 521 to rotate through the transmission member 511, so that the pulley 521 drives the belt 522 to rotate, thereby realizing the opening and closing of the curtain.
