Description

Technical Field

[0001] The utility model relates to the technical field of window openers, in particular to an electric window opener. Background Art

[0002] Electric window openers are a convenient window opening and closing device that allows users to easily control the opening and closing of windows through a remote control or switch without having to perform physical labor. Some electric window openers also have intelligent functions and can be remotely controlled by mobile phones, making the opening and closing of windows more convenient and intelligent.

[0003] When the existing electric window opener is in use, an internal driving mechanism is usually used to drive the chain to extend and open the glass window. When subjected to strong winds, the glass window will be subjected to a large thrust, and the method of connecting to the glass window through a single point is particularly insufficient. It is very easy for the chain and the glass window to break at the connection. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems.

DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] Example 1

[0023] See also Figure 1-6 An electric window opener comprises a frame 1, a glass window 2 hingedly mounted on the frame 1, and a window opener body 3 mounted on the frame 1, wherein the window opener body 3 comprises a fixing portion 4 fixedly mounted on the frame 1 and extension portions 5 symmetrically mounted at both ends of the fixing portion 4, wherein the fixing portion 4 and the extension portions 5 are both hollow structures, and strip holes 6 are provided on the sides of the two extension portions 5, and round rods 7 are movably provided in the extension portions 5 corresponding to the strip holes 6, and sleeves 8 are movably sleeved on the round rods 7, and the ends of the sleeves 8 are connected to the side of the glass window 2 through push-pull rods 9, wherein one end of the push-pull rod 9 is fixedly connected to the side wall of the sleeve 8, and the other end is connected to the glass window 2 through a universal joint 10, The window opener body 3 also includes a driving component, which is used to provide power for the relative movement of the two round rods 7. By setting a fixing portion 4 and two extension portions 5, when the window opener is installed, the window opener can be vertically fixed on the frame 1. When the driving component drives the round rods 7 in the two extension portions 5 to move relatively apart, the glass window 2 can be opened through the cooperation of the sleeve 8, the push-pull rod 9 and the universal joint 10. Conversely, when the two round rods 7 are driven relatively close, the glass window 2 can be closed, thereby realizing the opening and closing of the glass window 2. Compared with the prior art of realizing the opening and closing of the glass window 2 by a single chain, the impact resistance of the glass window 2 is improved when encountering strong winds.

[0024] A mounting plate 11 is fixedly provided on the side surface of the fixing portion 4 and the end of the extending portion 5 . The mounting plate 11 is in an “L”-shaped structure and can be detachably mounted on the frame 1 by screws.

[0025] Specifically, the driving assembly includes a double-axis motor 12, a screw 13 and a fixed rod 15. The screw 13 is rotatably arranged in the extension part 5, and a screw sleeve 14 adapted thereto is installed on the screw 13. The fixed rod 15 is fixedly arranged in the extension part 5 and arranged in parallel with the screw 13, and a sliding sleeve 16 is movably arranged on the fixed rod 15. The round rod 7 is fixedly installed between the sliding sleeve 16 and the screw sleeve 14. The double-axis motor 12 is fixedly installed in the fixed part 4, and the two output ends of the double-axis motor 12 are respectively connected to the screw 13. Specifically, when the double-axis motor 12 is controlled to rotate, the screws 13 in the two extension parts 5 can be driven to rotate at the same time. The screw sleeve 14 on the screw 13 cooperates with the sliding sleeve 16 on the fixed rod 15, so that the round rod 7 in the extension part 5 can move along the direction of the strip hole 6. Specifically, when the round rod 7 moves in a direction away from the fixed part 4, the glass window 2 can be pushed to open. Conversely, when the round rod 7 moves in a direction close to the fixed part 4, the glass window 2 can be closed.

[0026] Example 2

[0027] This embodiment is improved on the basis of embodiment 1, specifically:

[0028] See also Figure 2 , Figure 4 and Figure 6 The extension portion 5 is slidably inserted on the fixing portion 4, and the driving assembly also includes a transmission unit, which is used to transfer kinetic energy between the dual-axis motor 12 and the screw 13. Through such an arrangement, the length of the window opener can be appropriately adjusted according to the glass window 2 to be installed, so that the window opener can meet the needs of glass windows 2 of different specifications, further improving the practicality of the window opener. With the arrangement of the transmission unit, after the length of the window opener is changed, only one driving element is needed to drive the two screws 13 to rotate simultaneously, thereby reducing the production cost of the window opener.

[0029] Specifically, the transmission unit includes a sleeve 17 fixedly mounted on the output end of the dual-axis motor 12 and a telescopic rod 18 movably inserted in the sleeve 17, one end of the telescopic rod 18 is fixedly connected to the screw 13, and a plurality of bosses 19 are fixedly provided on the side wall of the end of the telescopic rod 18 located in the sleeve 17, and a side hole 20 is provided on the side wall of the sleeve 17 for the bosses 19 to slide. Specifically, after the two extension parts 5 are pulled to move outward from the fixed part 4, the telescopic rod 18 at the end of the screw 13 is always located in the sleeve 17, and when the dual-axis motor 12 drives the sleeve 17 to rotate, the cooperation of the boss 19 and the side hole 20 can make the screw 13 rotate therewith, thereby controlling the opening and closing of the glass window 2.

[0030] In addition, the outer wall of the extension portion 5 is also provided with scale lines 21. When the extension portions 5 at both ends of the fixed portion 4 are pushed or pulled outward or inward, the extended lengths of the two extension portions 5 can be intuitively observed by observing the scale lines 21, thereby ensuring that the window opener can be installed in the center position of the frame 1, further improving the practicability of the window opener.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
