Description

Technical Field

[0001] The utility model relates to the technical field of electric curtains, and specifically, to a window opener with buttons and digital display. Background Art

[0002] An electric window opener with buttons and digital display is a device that uses a mechanical transmission device to drive a sprocket to rotate to open and close doors and windows. Specifically, it performs the actions of opening and closing doors and windows by changing the direction of direct current voltage, and has now been widely used in fields such as fire smoke exhaust windows and motor skylights. Nowadays, there is already a chain window opener that can adjust the chain stroke. Users can adjust the chain stroke to make the doors and windows open at a certain angle. However, the existing chain window openers cannot visually adjust the opening form of the doors and windows. It entirely depends on the user to judge the opening angle of the doors and windows with the naked eye. Especially when applied to some large doors and windows, a large door and window usually requires multiple chain window openers to drive at the same time. The existing chain window openers ensure stroke synchronization. If the chain strokes of multiple window openers are inconsistent, it will cause uneven force on the doors and windows, unable to accurately open or close, and even cause damage to the doors and windows.

[0032] To further understand the content, features and effects of the present application, the following embodiments are exemplified and described in detail with reference to the drawings as follows.

[0033] Embodiment 1:

[0034] Refer to Figure 1 andFigure 2 , Figure 1 is a schematic structural view of the window opener with a button and a digital display in the first embodiment. Figure 2 is a schematic structural view of the window opener with a button and a digital display after removing the outer tube in the first embodiment. The window opener with a button and a digital display in this embodiment includes a housing member 1, a window opening member 2, and a display member 3. The window opening member 2 includes a driving body 21 and a chain. The driving body 21 is disposed inside the housing member 1, and the chain is connected to the output end of the driving body 21. The driving body 21 drives the chain to extend or retract from the housing member 1. The display member 3 includes a digital tube 31, a controller 32, and a control button 33. The digital tube 31 and the controller 32 are respectively disposed inside the housing member 1. The controller 32 is electrically connected to the driving body 21. The digital tube 31 is electrically connected to the controller 32 and is displayed through the housing member 1. One end of the control button 33 is connected to the controller 32, and the other end of the control button 33 is exposed outside the housing member 1.

[0035] The window opener with a button and a digital display in this embodiment is applied to various doors and windows such as skylights and smoke exhaust windows. Specifically, one end of the chain is connected with a window connecting block 221, and the window connecting block 221 is connected with the movable edge of the door and window. The driving body 21 drives the chain to extend or retract from the housing member 1. The chain is connected with the door and window through the window connecting block 221 and drives the door and window to open or close. The controller 32 in this embodiment is an existing motor power circuit board and a motor control circuit board, which is used to supply power to the driving body 21 and control the operation of the driving body 21. The digital tube 31 is connected to the control circuit board, and the digital tube 31 is displayed through the housing member 1, which is used to display the operation status of the driving body 21 in real time, and thus reflects the situation of the driving body 21 driving the chain, that is, reflects the size of the opening and closing of the door and window. The control button 33 is connected to the motor control circuit board. The user can cooperate with the digital tube 31 through the control button 33 and adjust and control the driving stroke of the driving body 21 through the controller 32. Further, a wireless transmission module is integrated on the control circuit board for intelligent connection with external terminals (such as mobile phones, computers, etc.). The driving body 21 can be controlled through the external terminal. Through the setting of the digital tube 31, the digital tube 31 can display the driving situation of the driving body 21 in real time. The user can intuitively observe the size of the opening and closing of the door and window through the displayed numbers on the digital tube 31. At the same time, through the setting of the control button 33, the visual adjustment of the stroke of the driving body 21 can be realized, so that it is convenient for the user to more accurately grasp the size of the opening and closing of the door and window. Especially when applied to large doors and windows, the user can adjust multiple window openers to the same stroke through the display of the digital tube 31 and the operation of the control button 33, avoiding damage to the doors and windows.

[0036] Refer to Figure 3 , Figure 3FIG. 0 is a schematic structural diagram of the window opening member in Embodiment 1. Preferably, the driving body 21 includes a motor 211 and a reduction gear set 212 connected to the driving end of the motor 211. Both the motor 211 and the reduction gear set 212 are disposed within the housing member 1. The reduction gear set 212 meshes with the chain. The motor 211 drives the chain to extend or retract from the housing member 1 through the reduction gear set 212. By providing the reduction gear set 212, the rotation speed of the motor 211 can be reduced, enabling the chain to extend or retract from the housing member 1 at an appropriate and slower speed, thereby enhancing the stability of the opening and closing of the doors and windows. Specifically, the housing member 1 is provided with a chain hole, and the chain within the housing member 1 extends or retracts from the housing member 1 through the chain hole. A worm is connected to the driving shaft of the motor 211. The reduction gear set 212 includes a plurality of rotating shafts 2121 and a plurality of gears 2122. Specifically, two gears 2122 are sleeved on each rotating shaft 2121, and the sizes and numbers of teeth of the two gears 2122 are different. The motor 211 meshes with the gear 2122 having more teeth on the rotating shaft 2121 through the worm, and the gear 2122 having fewer teeth on the rotating shaft 2121 meshes with the gear 2122 having more teeth on the next rotating shaft 2121. In this way, the rotation speed of the motor 211 is reduced in multiple stages. The chain is a dedicated chain for an existing window opener and meshes with the gear 2122 on the last rotating shaft 2121. The numbers of the rotating shafts 2121, gears 2122, and teeth can all be set according to actual needs and are not limited herein. It should be particularly noted that the digital tube 31 and the controller 32 in this embodiment are existing digital tubes and circuit boards that can be used in conjunction with the motor 211. The digital tube can display numbers from "00" to "99" and is used to reflect the opening size of the doors and windows.

[0037] Refer back to Figures 1 - 3 , preferably, the control button 33 includes a synchronization button and two stroke control buttons. One ends of the synchronization button and the two stroke control buttons are respectively connected to the controller 32, and the other ends of the synchronization button and the two stroke control buttons are respectively exposed outside the housing member 1. In specific applications, the two stroke control buttons control the rotation of the motor 211 by pressing the control circuit board, thereby respectively controlling the increase and decrease of the chain stroke, that is, controlling the opening size of the doors and windows. The control circuit board is also integrated with a communication module for synchronous communication with the controllers 32 of other chain window openers. It can be understood that multiple chain window openers achieve stroke synchronization through the communication module. That is, when the user presses the synchronization button of one of the chain window openers, the multiple controllers 32 respectively control the motors 211 of the multiple chain window openers to drive the same stroke. When applied to large doors and windows, it is convenient to synchronously set multiple chain window openers at the same time and can ensure that the strokes of the multiple chain window openers are consistent.

[0038] Refer to Figures 4 - 6 , Figure 4 FIG. is a schematic structural diagram of the sealing shell and the display member in Embodiment 1.Figure 5 Another structural schematic diagram of the sealed housing and the display component in Embodiment 1 Figure 6 Structural schematic diagram of the sealed housing and the display component after removing the front shell in Embodiment 1. Preferably, the display component 3 and the housing component 1 include an outer tube 11 and a sealed housing 12. An opening 111 is formed in the side wall of the outer tube 11. The sealed housing 12 is arranged inside the outer tube 11, and the display surface 1211 of the sealed housing 12 is exposed on the surface of the outer tube 11 through the opening 111. The digital tube 31 and the controller 32 are respectively arranged inside the sealed housing 12. The digital tube 31 performs display through the display surface 1211. The other end of the control button 33 is exposed outside the display surface 1211. The driving body 21 is arranged inside the outer tube 11 and drives the chain to extend or retract out of the outer tube 11. Through the arrangement of the sealed housing 12, the digital tube 31, the control circuit board and the power supply circuit board can be located inside the sealed housing 12. The sealed housing 12 can effectively prevent water from entering its interior, preventing the internal digital tube 31, control circuit board and power supply circuit board from being damaged due to contact with water, thus achieving a waterproof effect. Specifically, one surface of the sealed housing 12 is the display surface 1211, and there is a transparent area on the display surface 1211. The digital tube 31 performs display through this transparent area. The control button 33 is made of silica gel material. The control button 33 penetrates through the display surface 1211, and one end of the control button 33 is connected to the control circuit board, and the other end is located outside the sealed housing 12. Since the control button 33 is made of silica gel material and the display surface 1211 is a housing arranged on the surface of the sealed housing 12, the waterproof treatment is carried out between the control button 33 and the display surface 1211 through the cooperation mode of silica gel and the housing, further improving the waterproof effect of the sealed housing 12. Further, since the opening 111 is formed in the side wall of the outer tube 11 and the display surface 1211 of the sealed housing 12 is adapted to the opening 111, the display surface 1211 is snapped into the opening 111 during installation, so that the sealed housing 12 is stably installed inside the outer tube 11.

[0039] Refer back to Figures 4 - 6, preferably, the sealing housing 12 includes a front housing 121, a bottom housing 122 and a first sealing member 123. The front housing 121 and the bottom housing 122 are connected to form a waterproof cavity. The first sealing member 123 is sealed between the front housing 121 and the bottom housing 122. The display surface 1211 is arranged on the side of the front housing 121 away from the bottom housing 122. Both the controller 32 and the digital tube 31 are arranged in the waterproof cavity. Through the arrangement of the first sealing member 123, the sealing and waterproof performance between the front housing 121 and the bottom housing 122 is ensured, preventing water from entering the waterproof cavity and thus avoiding damage to the internal digital tube 31 and controller 32 caused by water ingress. Specifically, the first sealing member 123 is an O-ring. Connecting protrusions 1213 are provided on the side walls of the front housing 121 and the bottom housing 122. Through holes are provided in the connecting protrusions 1213. The motor 211 is provided with connecting grooves corresponding to the positions of the connecting protrusions 1213. The motor 211 and the sealing housing 12 are connected and fixed by inserting the connecting protrusions 1213 into the connecting grooves. The power supply lines of the control circuit board and the power supply circuit board pass through the through holes and are electrically connected to the motor 211.

[0040] Refer back to Figures 4 - 6 Preferably, mounting buckles 1221 are provided on the side wall of the bottom housing 122, and mounting grooves 1212 are provided on the front housing 121 corresponding to the positions of the mounting buckles 1221. The mounting buckles 1221 are snapped into the mounting grooves 1212 to fixedly connect the front housing 121 and the bottom housing 122. Through the arrangement of the mounting buckles 1221 and the mounting grooves 1212, on the one hand, the sealing and waterproof performance between the front housing 121 and the bottom housing 122 can be improved, and on the other hand, the front housing 121 and the bottom housing 122 can be detachably separated, facilitating the later maintenance or replacement of the internal digital tube 31 and controller 32. Specifically, in this embodiment, the number of both the mounting buckles 1221 and the mounting grooves 1212 is four. One mounting buckle 1221 is arranged in cooperation with one mounting groove 1212. Two of the mounting buckles 1221 are spaced apart and arranged on the side wall of the bottom housing 122, and the other two mounting buckles 1221 are spaced apart and arranged on the other side wall of the bottom housing 122. Of course, in other embodiments, the number and positions of the mounting buckles 1221 and the mounting grooves 1212 can be set according to actual needs and are not limited herein.

[0041] Refer to together Figure 7 and Figure 8 , Figure 7 is a schematic structural diagram of the outer tube in the first embodiment. Figure 8Figure 1 is a schematic structural diagram of the front end cover in Embodiment 1. Preferably, the housing member 1 further includes a front end cover 13 and a rear end cover 14, and the front end cover 13 and the rear end cover 14 are respectively and sealingly installed at both ends of the outer tube 11. In specific applications, the front end cover 13 is provided with a plurality of first mounting holes 134, and the outer tube 11 is provided with a plurality of second mounting holes 112 corresponding to the positions of the first mounting holes 134. Both the first mounting holes 134 and the second mounting holes 112 are threaded holes. Through the cooperation of the first mounting holes 134, the second mounting holes 112 and screws, the front end cover 13 can be fixedly installed at one end of the outer tube 11.

[0042] Refer back to Figure 7 and Figure 8 , preferably, a first fixing hole 132 is provided on the end face of the front end cover 13, and the front end cover 13 is fixed through the cooperation of the first fixing hole 132 and screws. The first fixing hole 132 is a threaded hole. Through the setting of the first fixing hole 132 and in combination with screws, the front end cover 13 can be fixed to the window and door bracket, that is, the chain window opener can be fixed by cooperating with the window and door bracket. Further, a second fixing hole 133 is provided on the side surface of the front end cover 13, and the front end cover 13 is fixed through the cooperation of the second fixing hole 133 and screws. The second fixing hole 133 is a threaded hole penetrating through the front end cover 13. Through the setting of the second fixing hole 133 and in combination with screws, the front end cover 13 can be directly fixed on the window and door, that is, the chain window opener can be directly fixed on the window and door without the need to rely on a bracket for fixing. In this way, two different installation and fixing methods can be realized. Specifically, the number of the second fixing holes 133 is multiple, and the multiple second fixing holes 133 are spaced apart and annularly arranged on the side surface of the front end cover 13, so that installation at different angles can be realized. The structure of the rear end cover 14 is similar to that of the front end cover 13 and will not be elaborated here.

[0043] Refer back to Figure 7 and Figure 8 , preferably, the sealing shell 12 is provided with a first wire outlet 124, and the front end cover 13 or the rear end cover 14 is correspondingly provided with a second wire outlet 131. The power cord of the controller 32 extends out of the housing member 1 through the first wire outlet 124 and the second wire outlet 131. A second sealing member is sealed between the first wire outlet 124 and the power cord and between the second wire outlet 131 and the power cord. In specific applications, the first wire outlet 124 and the second wire outlet 131 are used for routing wire harnesses such as the power cord and the synchronization line of the controller 32. After the power cord of the controller 32 passes through the first wire outlet 124 and the second wire outlet 131, it is connected to an external power source to supply power to the controller 32, the digital tube 31 and the motor 211. Specifically, the second sealing member is a sealing ring, which improves the waterproof and sealing performance of this embodiment. Of course, in other embodiments, caulking can also be used to waterproof and seal between the first wire outlet 124 and the power cord and between the second wire outlet 131 and the power cord.

[0044] Example Two:

[0045] Referring to Figure 9 , Figure 9 which is a schematic structural diagram of the window opener with buttons and digital display in Example Two. The difference between the window opener with buttons and digital display in this embodiment and that in Example One is that the sealing shell 12 in this embodiment is located outside the outer tube 11. The digital tube 31 and the controller 32 are respectively arranged in the sealing shell 12. The digital tube 31 performs display through the sealing shell 12. One end of the control button 33 is connected to the controller 32, and the other end of the control button 33 is exposed outside the sealing shell 12. The power cord of the controller 32 passes through the sealing shell 12 and the front end cover 13 in sequence and then extends into the outer tube 11 to be electrically connected to the driving body 21. The driving body 21 is arranged in the outer tube 11, and the driving body 21 drives the window opening part 22 to extend or retract from the outer tube 11. It can be understood that the outer tube 11 in this embodiment is installed on the doors and windows. The driving body 21 arranged in the outer tube 11 drives the chain to drive the window connecting block 221 to open and close the doors and windows. Since the sealing shell 12 and the outer tube 11 are separately arranged, the sealing shell 12 can be arranged at other positions such as indoors that are easy to operate at this time. In this way, not only the digital tube 31 and the controller 32 are far away from the doors and windows, avoiding the digital tube 31 and the controller 32 from easily contacting rainwater, etc., but also it is convenient for users to operate and control through the control button 33, and the reading on the digital tube 31 can be observed more closely and intuitively, improving convenience and practicality. Of course, a sealing ring is arranged at the position where the power cord passes through the sealing shell 12 and the front end cover 13 or waterproof sealing is carried out by caulking.

[0046] Example Three:

[0047] The difference between the window opener with buttons and digital display in this embodiment and that in Example One is that the driving body 21 in this embodiment is a push rod motor, and the window opening part 22 is a push rod. The push rod motor includes a motor 211 and a lead screw pair 213. The motor and the lead screw pair 213 are both arranged in the outer tube 11. The sealing shell 12, the digital tube 31 and the controller 32 are also arranged in the outer tube 11. One end of the push rod is connected to the lead screw pair 213, and the other end passes through the rear end cover 14 and extends towards the outside of the outer tube 11. The motor drives the push rod through the lead screw pair 213 to perform reciprocating linear movement, and a window connecting block 221 is connected to the other end of the push rod. The window connecting block 221 is connected to the frame of the doors and windows and is used to push to open and close the doors and windows. It can be understood that in this embodiment, the push rod is used to push to open and close the doors and windows, while in Example One, the doors and windows are opened and closed by the chain extending and retracting. Specifically, the sealing shell 12 in this embodiment is arranged in the outer tube 11, that is, the driving body 21, the digital tube 31 and the controller 32 are all arranged in the outer tube 11, which is an integrated structure.

[0048] Example Four:

[0049] Referring toFigure 10 and Figure 11 , Figure 10 FIG. Figure 10 is a schematic structural diagram of the window opener with a button and a digital display in Embodiment 3 and Embodiment 4. Figure 11 FIG. Figure 11 is a schematic structural diagram of the window opening member after removing the outer tube in Embodiment 4. In this embodiment, the driving body 21 is a push rod motor, and the window opening part 22 is a push rod. The push rod motor includes a motor and a lead screw pair 213. Both the motor and the lead screw pair 213 are arranged inside the outer tube 11. One end of the push rod is connected to the lead screw pair 213, and the other end passes through the rear end cover 14 and extends towards the outside of the outer tube 11. The motor is connected to the push rod through the lead screw pair 213 to drive the push rod to perform reciprocating linear movement. And a window connecting block 221 is connected to the other end of the push rod. The window connecting block 221 is connected to the frame of the door or window for pushing to open and close the door or window. It can be understood that in this embodiment, the push rod is used to push to open and close the door or window, while in Embodiment 3, the door or window is opened and closed by the extension and retraction of the chain. Specifically, the sealing shell 12 in this embodiment is arranged outside the outer tube 11. The power cord of the controller 32 in the sealing shell 12 passes through the sealing shell 12 and the front end cover 13 in sequence and then extends into the outer tube 11 to be electrically connected to the driving body 21. That is, the window opening member 2 and the display member 3 are of a split design. In this way, the window opening member 2 can be installed on the door or window for opening and closing the door or window, and the display member 3 can be installed at a position convenient for users to operate and observe, improving convenience and practicality.

[0050] In summary, through the setting of the digital tube 31, the digital tube 31 can display the driving situation of the driving body 21 in real time. Users can intuitively observe the size of the opening and closing of the door or window through the displayed numbers on the digital tube 31. At the same time, through the setting of the control button 33, the visual adjustment of the stroke of the driving body 21 can be realized. In this way, it is convenient for users to more accurately grasp the size of the opening and closing of the door or window. Especially when applied to large doors and windows, users can adjust multiple window openers to the same stroke through the display of the digital tube 31 and the operation of the control button 33, avoiding damage to the doors and windows. In addition, a synchronization button is also set on the controller 32, which is convenient for synchronously setting multiple window openers and can ensure that the strokes of multiple window openers are consistent.
