DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the implementation methods of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Embodiment 1:

[0026] The utility model provides a chain-type electric window opener, please refer to Figure 1-3 , comprising a housing 1, a servo motor 17 is mounted on the housing 1, a box body 16 is mounted on the top of the housing 1 by bolts, the servo motor 17 is arranged in the box body 16, a first sprocket 2, a chain 6 and a second sprocket 3 are all located in the housing 1, a first sprocket 2 is fixedly mounted on an output shaft 4 of the servo motor 17, the first sprocket 2 is transmission-connected to the chain 6, the other end of the chain 6 is transmission-connected to the second sprocket 3, the inner wall of the second sprocket 3 is fixedly connected to a support shaft 5, and the support shaft 5 is rotationally connected to the housing 1;

[0027] A driver is fixedly mounted on the chain 6, and the driver is docked with the window. The driver moves with the transmission of the chain 6 to realize the opening and closing of the window;

[0028] After the chain electric window opener is installed, the servo motor 17 drives the first sprocket 2 to rotate, referring to Figure 1 , causing the first sprocket 2 to rotate counterclockwise, thereby causing the chain 6 to be driven, thereby driving the upper driver to move to the left and the lower driver to move to the right, thereby causing the first window 14 and the second window 13 to be opened.

[0029] A bearing seat 19 is installed on the bottom wall of the inner cavity of the shell 1 by bolts. The bearing seat 19 is rotatably connected to the support shaft 5 through a bearing. The shell 1 is installed on the top of the window frame 15 by bolts.

[0030] A window frame 15 is provided below the housing 1 , and a first window 14 and a second window 13 are slidably connected to the window frame 15 .

[0031] A groove 151 is provided at the bottom of the window frame 15, and sliders 20 are fixedly installed at the bottom of the first window 14 and the second window 13. The inner wall of the groove 151 is slidably connected to the slider 20, and the slider 20 slides in the groove 151, thereby enabling the movement of the first window 14 and the second window 13 to be smoother.

[0032] Two groups of drivers are provided, and the drivers include a U-shaped fixing block 11 fixedly mounted on the chain 6, a supporting pin 12 fixedly mounted on the U-shaped fixing block 11, and a mounting block 10 fixedly connected to one end of the supporting pin 12 away from the U-shaped fixing block 11. The mounting blocks 10 in the two drivers are fixedly connected to the top ends of the first window 14 and the second window 13, respectively.

[0033] When the first window 14 and the second window 13 need to be opened in specific use, the servo motor 17 is started to drive the first sprocket 2 to rotate. Figure 1 , so that the first sprocket 2 rotates counterclockwise, and then the chain 6 is driven to drive, thereby driving the upper driver to move to the left, and the lower driver to move to the right, so that the first window 14 and the second window 13 are opened; and when the first window 14 and the second window 13 need to be closed, the servo motor 17 drives the first sprocket 2 to rotate in the opposite direction, referring to Figure 1 , causing the first sprocket 2 to rotate counterclockwise, thereby causing the chain 6 to be driven, thereby driving the upper driver to move to the right and the lower driver to move to the left, thereby closing the first window 14 and the second window 13.

[0034] Embodiment 2:

[0035] Refer to the attached Figure 4-5 , which is different from the first embodiment: rollers are fixedly mounted at the bottom ends of the first window 14 and the second window 13;

[0036] The roller includes a wheel frame 141 fixedly mounted at the bottom of the first window 14 and the second window 13, a roller 142 is rotatably connected to the wheel frame 141 via a bearing, and the bottom of the roller 142 contacts the bottom wall of the groove 151;

[0037] Therefore, during the movement of the first window 14 and the second window 13, the roller 142 rolls in the groove 151, so that the movement of the first window 14 and the second window 13 is not only smoother, but also the friction between the first window 14 and the second window 13 and the window frame 15 is smaller during the movement, which can effectively reduce the friction noise generated when opening and closing the first window 14 and the second window 13.

[0038] When the first window 14 and the second window 13 need to be opened in specific use, the servo motor 17 is started to drive the first sprocket 2 to rotate. Figure 1, so that the first sprocket 2 rotates counterclockwise, and then the chain 6 is driven to drive, thereby driving the upper driver to move to the left, and the lower driver to move to the right, so that the first window 14 and the second window 13 are opened; and when the first window 14 and the second window 13 need to be closed, the servo motor 17 drives the first sprocket 2 to rotate in the opposite direction, referring to Figure 1 , causing the first sprocket 2 to rotate counterclockwise, thereby causing the chain 6 to be driven, thereby driving the upper driver to move to the right and the lower driver to move to the left, thereby closing the first window 14 and the second window 13.

[0039] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
