[0002] A window opener is a machine used to open and close windows. It's also known as a "window opener" or "window opener." It's generally called a "window opener" abroad, but in China, it's more commonly called a "window opener." There are many different types of electric window openers, including rack-type electric window openers, small chain-type electric window openers, and screw-type electric window openers.

[0003] Screw-type electric window openers utilize a screw and nut that work together to drive an outward-extending extension tube, opening or closing the window sash. To better control the power motor that drives the screw, an electronic sensor can be installed at the end of the motor. However, since the window opener contains internal cables, there's a risk that the cables could interfere with the electronic sensor, necessitating protection.

[0004] Therefore, how to optimize the installation structure so that the internal structure of the window opener can protect the electronic sensing equipment while simplifying the installation process and improving production efficiency is a technical problem that needs to be solved.

DETAILED DESCRIPTION

[0029] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 5 In an embodiment of the utility model, a window opening machine with an optimized installation structure includes a shell 10 and a power device 20 and an extension mechanism 30 installed inside the shell 10. The power device 20 is fixed to the inside of the shell 10, and one end of the extension mechanism 30 is transmission-connected to the output end of the power device 20, and the other end is provided with a hinge terminal 31, and the hinge terminal 31 is used to hinge the external window sash; the power device 20 is provided with a power motor 21 and a power reducer 23, the output shaft of the power motor 21 is transmission-connected to the input end of the power reducer 23, and the output end of the power reducer 23 is transmission-connected to the input end of the extension mechanism 30; the power motor 21 is provided with a sensor component 40 at one end away from the power reducer 23, and the sensor component 40 is provided with a sensor circuit board 41 and a protective cover 42, and the protective cover 42 is snap-fitted and connected to the sensor circuit board 41, thereby protecting the electronic components on the sensor circuit board 41.

[0031] Specifically, a window opener is usually connected to an external window frame at one end and to an external window sash at the other end. The external window sash is opened or closed by the operation of the window opener. As for a screw 32-type window opener, in order to optimize the installation space it occupies, it is usually set to be relatively small, so the space inside its shell 10 is relatively tight, especially the power motor 21 part. It is preferred to directly design the outer wall of the power motor 21 to abut against the inner wall of the shell 10, thereby reducing the diameter of the shell 10. Therefore, in order to better control the power motor 21 that drives the screw 32, the electronic sensor device set at the tail end of the power motor 21 occupies a relatively limited space. At the same time, because there are cables inside the window opener, there may be a problem that the cables affect the electronic sensor device, and the electronic sensor device needs to be protected.

[0032] Secondly, when setting up the protective cover 42, it is also necessary to consider how to fix it. Similarly, due to the limited internal size of the housing 10, the sensor circuit board 41 can be directly welded through the power terminal 22 of the power motor 21 to be fixed to the power motor 21. This can not only simplify the installation of the sensor circuit board 41 at the tail end of the power motor 21, but also form an electrical connection between the power motor 21 and the sensor circuit board 41, further reducing the complexity of the connection between the power motor 21 and the external cable, and optimizing the installation process and production steps.

[0033] like Figure 4 and Figure 5 As shown, preferably, the protective cover 42 is provided with a circuit through hole 43, and the circuit through hole 43 is used to pass the conductive cable of the sensor circuit board 41, so that the sensor circuit board 41 is electrically connected to the external cable.

[0034] Specifically, preferably, the sensor circuit board 41 is directly electrically connected to the power motor 21 via the power terminals 22, and a corresponding electrical connection is also required between the sensor circuit board 41 and an external cable, or between the sensor circuit board 41 and the control circuit board 11. Preferably, a line through hole 43 is provided in the protective cover 42, so that the corresponding cable passes through the line through hole 43 and enters the protective cover 42 to form an electrical connection with the sensor circuit board 41.

[0035] like Figure 4 and Figure 5 As shown, preferably, the side wall of the protective cover 42 is provided with a plurality of snap-fit pieces 44, and the snap-fit pieces 44 are used to snap-fit and connect to the side of the sensor circuit board 41 away from the protective cover 42. The side wall of the protective cover 42 is also provided with a limit block 45, and the limit block 45 is arranged between two snap-fit pieces 44 and abuts against the side of the sensor circuit board 41 close to the protective cover 42.

[0036] Specifically, the multiple snap tabs 44 on the sidewalls of the protective cover 42 are preferably evenly spaced and dispersed, allowing them to snap onto the sensor circuit board 41 from multiple angles or positions, allowing for direct snap-on connection to the sensor circuit board 41, further simplifying installation and improving installation efficiency. Furthermore, the stoppers 45 prevent the protective cover 42 from squeezing the electronic components on the sensor circuit board 41, ensuring that the protective cover 42 itself does not obstruct or damage the sensor electronic components on the sensor circuit board 41. Furthermore, a certain distance between the protective cover 42 and the sensor circuit board 41 is maintained, creating a corresponding accommodation space.

[0037] like Figure 1 As shown, preferably, a control circuit board 11 is further provided in the housing 10 , and the control circuit board 11 is electrically connected to the sensor circuit board 41 , thereby receiving the electronic sensor signal of the sensor circuit board 41 and providing operating power for the power motor 21 at the same time.

[0038] Specifically, in order to control or power the window opener, a corresponding control circuit board 11 may be provided, along with necessary electronic components such as a control chip and a power chip. The control chip may control the window opener according to a preset program, while the power chip may regulate the external power supply.

[0039] like Figures 1 to 3As shown, preferably, the extending mechanism 30 is provided with a screw 32, a nut 33 and an extension tube 34, one end of the screw 32 is transmission-connected to the output end of the power reducer 23, and the other end thereof is movably connected to the extension tube 34, the outer ring of the nut 33 is slidingly connected to the inner wall of the shell 10, and the inner ring thereof is sleeved on the screw 32 and forms a transmission connection therewith; one end of the extension tube 34 is fixed to the nut 33 and moves synchronously therewith, and the other end thereof is fixed to the hinge terminal 31, and can extend out of the shell 10, thereby performing an opening and closing operation on the external window sash.

[0040] Preferably, the end of the housing 10 extending from the extension tube 34 is provided with a first end cap 12. An extension through-hole 13 is defined in the center of the first end cap 12, and the outer wall of the extension tube 34 is slidably connected to the extension through-hole 13. A second end cap 14 is provided at the end of the housing 10 where the control circuit board 11 is mounted. The second end cap 14 is secured to the housing 10 and forms a seal therewith.

[0041] Specifically, in order to open or close the external window sash, a corresponding screw 32 and nut 33 can be provided to drive the extension tube 34 to extend outward, and the hinge terminal 31 connected by the extension tube 34 is hinged to the external window sash, thereby opening or closing the external window sash. It is understandable that the external window sash and the hinge terminal 31 can be connected by bolts, or can be rotatably connected by a hinge seat in existing products. When the extension tube 34 is extended outward or retracted inward, the external window sash can be opened and closed. In addition, the housing 10 of the window opener itself can also be connected to the external window frame by bolts, or can be installed accordingly through the mounting seat in existing products so that it can operate normally.

[0042] Secondly, since the window opener needs to frequently open the window sash, which may get wet due to rain, it is preferred to install a first end cap 12 and a second end cap 14 at each end of the housing 10, and to install corresponding waterproof rubber rings (not shown in the figure). Since the first end cap 12 needs to have an extension hole 13 to allow the extension tube 34 to extend outward normally, a lubricating and wear-resistant waterproof component can also be added between the extension hole 13 and the extension tube 34. This prevents moisture from entering the extension tube 34 during its extension and retraction, while allowing it to move smoothly and normally. The second end cap 14 is also fixedly connected to a corresponding cable, which provides operating power to the control circuit board 11. The location of the cable is preferably waterproofed with a corresponding waterproof rubber ring.

[0043] It will be apparent 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 essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
