DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0026] The embodiment of the present application provides a new type of electric chain window opener to solve the technical problems existing in the existing related technologies: in order to meet the predetermined window opening stroke, the length of the chain usually needs to be set longer, so that the length of the window opener housing needs to be set longer accordingly, resulting in a larger volume of the overall structure of the window opener. It is not suitable for application scenarios with small installation space and is not conducive to reducing production costs. The following will be explained in conjunction with the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of a novel electric chain window opener provided in an embodiment of the present application, Figure 2A schematic diagram of the internal structure of a novel electric chain window opener provided in an embodiment of the present application. A novel electric chain window opener provided in an embodiment of the present application includes a window opener body 100. Specifically, the window opener body 100 includes a housing 10 and a chain 20, a sprocket 31 and a power mechanism 30 arranged in the housing 10, wherein the housing 10 is a hollow rectangular shell, and an opening 103 is provided through one side of the housing 10. A guide column 13 is provided in the housing 10, and the guide column 13 can be set as a column with a circular cross section; the chain 20 can adopt the chain 20 commonly used in the existing related technology, and one end of the chain 20 (for the convenience of description, this end is defined as the chain tail 22 below) is fixed to the guide column 13, and specifically, the chain tail 22 of the chain 20 can be detachably fixed to the guide column 13 by fasteners such as screws and bolts; the sprocket 31 is rotatably arranged in the housing 10, and the sprocket 31 and the guide column 13 are spaced apart by a predetermined distance (the predetermined distance can be selected and set according to the actual length of the housing 10) along the length direction of the housing 10. With respect to the setting, the end of the chain 20 away from the guide column 13 (for the convenience of description, this end is defined as the chain head 21 below) extends a predetermined length in the direction close to the sprocket 31 (the predetermined length can be selected and set according to the actual length of the chain 20. For example, in the embodiment of the present application, the predetermined length is set to be approximately equal to one third of the total length of the chain 20), then bends back and wraps around the side of the guide column 13 away from the sprocket 31, and extends out of the opening 103 after engaging with the sprocket 31. The end of the chain 20 extending from the opening 103, i.e., the chain head 21, is used to be fixed to the window. Specifically, the chain head 21 can be fixed to the bottom or side of the window by fasteners such as screws; the power mechanism 30 is used to drive the sprocket 31 to rotate, so that when the sprocket 31 rotates, it can drive the chain 20 to move, so that the chain head 21 of the chain 20 extends from or retracts from the opening 103 of the housing 10, and then drives the window to achieve the purpose of automatic window opening or closing.

[0028] By adopting the above technical solution, by setting the guide column 13, and making the sprocket 31 and the guide column 13 relatively arranged at a predetermined distance along the length direction of the housing 10, one end of the chain 20 is fixed to the guide column 13, and the end of the chain 20 away from the guide column 13 extends toward the sprocket 31 for a predetermined length, then bends back and passes through the peripheral side of the guide column 13 away from the sprocket 31, and then engages with the sprocket 31 and extends from the opening 103. In this way, under the action of the guide column 13, the chain 20 is limited and guided, and when the housing 10 is small in size, the power mechanism 30 can still make the chain 20 rotate smoothly, and the length of the chain 20 that can be set in the housing 10 is extended to a certain extent, so that the volume of the housing 10 can be set smaller under the premise of ensuring the window opening stroke, so that the window opener can be suitable for application scenarios with small installation space, improving the applicability of the window opener, and also helping to reduce production costs.

[0029] Specifically, refer to Figure 2 and Figure 3 , Figure 3 for Figure 2 A schematic diagram of the internal structure of a novel electric chain window opener when no chain is provided. In some embodiments, the housing 10 includes an inner bottom 11, a guide post 13 is provided on the inner bottom 11, a sprocket 31 is provided on the side of the inner bottom 11 away from the guide post 13, and a partition 14 is provided on the inner bottom 11. The partition 14 is provided along the length direction of the housing 10, one end of the partition 14 abuts against the guide post 13, and the other end of the partition 14 extends toward the sprocket 31. The height of the partition 14 can be consistent with the thickness of the chain 20. Specifically, the plane where the partition 14 is located can be set to be tangent to the peripheral side of the guide post 13, the chain head 21 is located on one side of the partition 14, the chain 20 extends along the side of the partition 14 for a predetermined length, then bends back and surrounds the peripheral side of the guide post 13 away from the sprocket 31, and the bent end of the chain 20 is located on the other side of the partition 14. In this way, the shape of the chain 20 is restricted to a certain extent by the partition 14, so that the chain 20 is kept in a relatively straight state, and the chain 20 can move according to a predetermined trajectory, thereby avoiding the chain 20 from being unable to move smoothly due to the bending of the chain 20, and then causing the window to be unable to be opened or closed. In addition, the partition 14 is used to separate, so that the length of the chain 20 that can be set is guaranteed, thereby ensuring the window opening or closing stroke, which is conducive to improving the applicability and working reliability of the window opener, and making the structure of the inner bottom 11 compact and simple, and easy to manufacture. Among them, the inner bottom 11 can be formed by plastic injection molding, and the guide column 13 and the partition 14 are integrally formed with the inner bottom 11, so that the overall structural strength is guaranteed, and it is also easy to manufacture.

[0030] Further, see Figure 3 and Figure 4 , Figure 4Exploded diagram of the bottom plate, cover plate and power mechanism provided in the embodiment of the present application. In some embodiments, the side of the inner bottom 11 away from the guide column 13 is provided with a bottom plate 101 and a cover plate 102 that overlap each other, and the bottom plate 101 is provided with a first mounting position 1011 for mounting the sprocket 31, and the first mounting position 1011 can be set as an annular protrusion opened on the bottom plate 101, and the sprocket 31 is rotatably mounted on the first mounting position 1011 of the bottom plate 101 through a rotating shaft, and the end of the chain 20 away from the guide column 13 bypasses from the side of the sprocket 31 away from the guide column 13 and meshes with the sprocket 31. In order to make the force of the chain 20 acting on the window perpendicular to the plane where the window is located, an arc-shaped guide groove 15 can be opened on the cover plate 102, one end of the arc-shaped guide groove 15 faces the end of the partition plate 14 close to the sprocket 31, and the other end of the arc-shaped guide groove 15 is connected to the opening 103 of the housing 10, and the end of the chain 20 away from the guide column 13 is accommodated in the arc-shaped guide groove 15, and the chain head 21 of the chain 20 can extend from the opening 103. Further, in some implementations, in order to make the chain 20 rotate smoothly, a rounded corner (not shown in the figure) adapted to the chain 20 can be set on the inner bottom 11 near the guide column 13 and around the side wall of the chain 20.

[0031] Further, see Figure 4 and Figure 5 In some embodiments, the power mechanism 30 includes a first gear 32, a worm 36 and a motor 37. The first gear 32 is coaxially fixed with the sprocket 31. The first gear 32 is rotatably arranged at the first installation position 1011 through the rotating shaft. The motor 37 is arranged on the bottom plate 101. The axis of the output shaft of the motor 37 is perpendicular to the axis of the rotating shaft of the first gear 32. Specifically, a holder 1015 for engaging with the peripheral side of the motor 37 can be arranged on the bottom plate 101. The motor 37 is positioned at a predetermined position on the bottom plate 101 through the holder 1015. The worm 36 is coaxially fixed to the output shaft of the motor 37. The worm 36 can be connected to the first gear 32 in a transmission manner. In this way, when the motor 37 is working, the power is transmitted to the first gear 32 through the worm 36, so that the sprocket 31 rotates. When the sprocket 31 rotates, the chain 20 can be driven to move, thereby achieving the purpose of automatically opening or closing the window. The overall structure is simple and compact.

[0032] Furthermore, in some embodiments, in order to improve the reliability of power transmission, the power mechanism 30 may also include a second gear 33, a third gear 34 and a fourth gear 35. Accordingly, a second mounting position 1012, a third mounting position 1013 and a fourth mounting position 1014 for respectively mounting the second gear 33, the third gear 34 and the fourth gear 35 may be provided on the bottom plate 101. The second mounting position 1012, the third mounting position 1013 and the fourth mounting position 1014 may all be set as annular protrusions with reference to the first mounting position 1011, or, according to the specific structure, the second mounting position 1012, the third mounting position 1013 and the fourth mounting position 1014 may be set as circular depressions. , wherein the second gear 33 is rotated at the second installation position 1012 by a rotating shaft and is located on the side of the first gear 32 close to the motor 37, the third gear 34 is rotated at the third installation position 1013 by a rotating shaft and is located on the side of the second gear 33 close to the motor 37, the fourth gear 35 is rotated at the fourth installation position 1014 by a rotating shaft and is located on the side of the third gear 34 close to the motor 37, specifically, the second gear 33 includes a second meshing portion 331 for meshing with the first gear 32, the third gear 34 includes a third meshing portion 341 for meshing with the second gear 33, the fourth gear 35 includes a fourth meshing portion 351 for meshing with the third gear 34, and the fourth gear 35 meshes with the worm 36. Among them, the diameter of the first gear 32 is larger than the diameter of the second gear 33, the diameter of the second gear 33 is larger than the diameter of the third gear 34, the diameter of the third gear 34 is larger than the diameter of the fourth gear 35, and the specific sizes of the diameters of the first gear 32, the second gear 33, the third gear 34 and the fourth gear 35 can be selected and set according to the size of the sprocket 31 and the specific stroke of the opening and closing window. In this way, when the motor 37 is working, the power is transmitted to the fourth gear 35 through the worm 36, and the fourth gear 35 transmits the power to the third gear 34, the second gear 33 and the first gear 32 in sequence, so that the sprocket 31 rotates. When the sprocket 31 rotates, it can drive the chain 20 to move, thereby achieving the purpose of automatically opening or closing the window. The overall structure is simple and ingenious, and can achieve deceleration. At the same time, the overall structure is compact and stable, and the working reliability is good, which is conducive to ensuring the working reliability of the window opener.
