DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Embodiment 1 Existing chain window openers often adjust the opening and closing degree of windows by adjusting the stroke of the chain, and lack an anti-pinch function. When there are impurities or other foreign matter between the window frame and the window sash, or when the window frame is affected by temperature due to long-term use and expands and deforms, when the chain window opener is in the process of closing the window, after the window sash contacts the foreign matter or the expanded and deformed window frame, the chain still has a short stroke, and the motor continues to rotate, posing a safety hazard and causing damage to the chain window opener and the window, affecting the service life of the chain window opener and the window.

[0023] See also Figures 1 to 7 The present invention provides the following technical solution: an intelligent electric window opener, comprising a housing 1 and a driving motor 2, a transmission mechanism 3 and a chain 4 arranged inside the housing 1, and further comprising: The connecting mechanism 5 is arranged on one end of the chain 4 extending to the outside of the shell 1. The connecting mechanism 5 includes a connecting member 51 and a movable component 52 arranged inside the connecting member 51. The position of the movable component 52 inside the connecting member 51 is moved to adjust the length of the connecting mechanism 5.

[0024] The driving assembly 6 is arranged inside the shell 1. The driving assembly 6 includes a rotating shaft 61 and a clamping assembly 62 arranged inside the rotating shaft 61. A limiting member 63 is provided at one end of the clamping assembly 62 away from the rotating shaft 61. A first accommodating groove 64 and a first limiting groove 65 that are interconnected are opened inside the end of the limiting member 63 close to the clamping assembly 62. Moving the clamping assembly 62 into the first accommodating groove 64 and the first limiting groove 65 can make the rotating shaft 61 and the limiting member 63 rotate synchronously.

[0025] The transmission mechanism 3 is composed of a transmission shaft, gears, bearings, etc. The driving motor 2 can drive the movement of the chain 4 through the transmission mechanism 3. The prior art will not be described in detail.

[0026] like Figures 4 to 6As shown, the connecting mechanism 5 also includes a first mounting member 53 fixedly connected to one end of the chain 4 extending to the outside of the shell 1, and the end of the connecting member 51 away from the chain 4 is fixedly connected to the second mounting member 54 for connecting the window, and the connecting member 51 is provided with an extrusion groove 511 and an adjustment groove 512 that are interconnected, and the connection between the extrusion groove 511 and the adjustment groove 512 is arranged in an arc shape. The movable component 52 includes a moving member 521 that is slidably connected to the inner wall of the adjustment groove 512 and the extrusion groove 511, and the end of the moving member 521 away from the second mounting member 54 passes through the connecting member 51 and is fixedly connected to the first mounting member 53, and the moving member 521 is slidably connected to the connecting member 51, and two symmetrically arranged first sliding grooves 522 are provided inside the other end of the moving member 521, and each first sliding groove 522 is slidably connected to the inside of a first extrusion member 523, and a first elastic member 524 is connected between the side of the two first extrusion members 523 that are close to each other and the inner wall of the corresponding first sliding groove 522.

[0027] The connection between the extrusion groove 511 and the adjustment groove 512 is arranged in an arc shape, so as to facilitate the first extrusion member 523 to move from the inside of the adjustment groove 512 to the inside of the extrusion groove 511 .

[0028] The adjusting groove 512 is arranged on one side of the connecting member 51 close to the second mounting member 54, the extrusion groove 511 is arranged on one side of the connecting member 51 close to the first mounting member 53, and the inner wall of the extrusion groove 511 is provided with a pressure sensor 55 corresponding to the position of the first extrusion member 523. When the movable member 521 moves from the adjusting groove 512 to the extrusion groove 511, the two first extrusion members 523 can be squeezed by the inner wall of the extrusion groove 511, so that the two first extrusion members 523 can move in a direction close to each other, and can squeeze the two first elastic members 524. When the movable member 521 moves to the extreme position inside the extrusion groove 511, the movable member 521 can contact with the corresponding pressure sensor 55, so that the pressure sensor 55 can generate a detection signal.

[0029] When the moving member 521 moves to the extreme position inside the extrusion groove 511, that is, the moving member 521 moves to the side of the extrusion groove 511 close to the chain 4, the moving member 521 can correspond to and contact the pressure sensor 55, and the pressure sensor 55 generates a detection signal through the force of the first elastic member 524.

[0030] like Figure 5As shown, when the electric window opener is opening the window, affected by the thrust of the chain 4 and the window opening resistance, the first mounting member 53 can push the end of the movable member 521 provided with the first extruding member 523 to enter the interior of the adjusting groove 512 and contact the inner wall of the adjusting groove 512. At this time, the two first elastic members 524 are not compressed, and the two first extruding members 523 are away from each other. The two first extruding members 523 can be limited by the connection between the extruding groove 511 and the adjusting groove 512. When the electric window opener is closing the window, the chain 4 is wound up, and the first extruding member 523 can be limited by the connection between the extruding groove 511 and the adjusting groove 512. The winding of the chain 4 can drive the connecting member 51 to move synchronously through the first extruding member 523, so that the window can be closed. When the electric window opener is closing the window, if there are impurities and other foreign matter between the window frame and the window sash, these foreign matter will increase the closing resistance of the electric window opener when they come into contact with the window sash, and can overcome the elastic force of the first elastic member 524, so that the first extrusion member 523 moves from the inside of the adjustment groove 512 to the inside of the extrusion groove 511, so that the two first extrusion members 523 move in a direction close to each other, and can squeeze the two first elastic members 524 until the moving member 521 moves to the extreme position inside the extrusion groove 511. Under the action of the first elastic member 524, the moving member 521 can be contacted and squeezed with the corresponding pressure sensor 55, and the pressure sensor 55 can generate a detection signal and transmit it to the controller 7 for processing and analysis.

[0031] A controller 7 is disposed inside the housing 1 , and the pressure sensor 55 , the electromagnet 67 and the driving motor 2 are all electrically connected to the controller 7 .

[0032] The controller 7 can receive the detection signal of the pressure sensor 55 , and the controller 7 can control the working states of the electromagnet 67 and the driving motor 2 .

[0033] It should be noted that when there are impurities or other foreign matter between the window frame and the window sash, or when the window frame is affected by temperature due to long-term use and expands and deforms, when the electric window opener is in the process of closing the window, when the window sash contacts the foreign matter or the expanded and deformed window frame, the resistance of the electric window opener when closing the window is increased, and the force between the moving member 521 and the connecting member 51 is increased, which can overcome the elastic force of the first elastic member 524, so that the first extrusion member 523 moves from the inside of the adjustment groove 512 to the inside of the extrusion groove 511, so that the two first extrusion members 523 are close to each other, which can squeeze the two first elastic members 523. Part 524, until the movable part 521 moves to the extreme position inside the extrusion groove 511, under the action of the first elastic part 524, the movable part 521 can be brought into contact with the corresponding pressure sensor 55, and the pressure sensor 55 can generate a detection signal and transmit it to the controller 7. The controller 7 which receives the detection signal of the pressure sensor 55 can control the drive motor 2 to stop working, thereby preventing the motor from continuously rotating, realizing the anti-pinch function, improving the safety performance, and effectively preventing the continuous rotation of the motor from damaging the chain window opener and the window, thereby improving the service life of the chain window opener and the window.

[0034] In summary, the present invention, through the setting of the connecting mechanism 5, when there are impurities and other foreign matter between the window frame and the window sash of the window, or when the window frame is affected by temperature due to long-term use and expands and deforms, when the electric window opener is in the process of closing the window, when the window sash contacts the foreign matter or the expanded and deformed window frame, the resistance of the electric window opener when closing the window will increase, and the elastic force of the first elastic member 524 can be overcome, so that the first extrusion member 523 moves from the inside of the adjustment groove 512 to the inside of the extrusion groove 511 until the moving member 521 moves to the extreme position inside the extrusion groove 511. Under the action of the first elastic member 524, the moving member 521 can contact the corresponding pressure sensor 55, generate a detection signal, and transmit it to the controller 7, and control the drive motor 2 to stop working, thereby avoiding continuous rotation of the motor, realizing the anti-pinch function, improving safety performance, and effectively avoiding damage to the chain window opener and the window caused by continuous rotation of the motor, thereby improving the service life of the chain window opener and the window.

[0035] Embodiment 2 Based on the above embodiment, the chain window opener mainly relies on electric drive. Once the power fails, the motor stops working and is affected by the resistance of multiple gears in the transmission mechanism. After clamping foreign objects, the window cannot be opened and closed manually, and it is difficult to remove the foreign objects, which affects its use.

[0036] See also Figures 8 to 13The driving assembly 6 also includes a transmission gear 66 fixedly connected to the outer wall of the rotating shaft 61, the rotating shaft 61 is rotatably connected to the inner wall of the shell 1, and the outer wall of the rotating shaft 61 is rotatably connected to an electromagnet 67, the electromagnet 67 is arranged above the transmission gear 66, and the outer wall of the electromagnet 67 is fixedly connected to a fixing part 68 fixedly connected to the inner wall of the shell 1.

[0037] The electromagnet 67 is prevented from rotating by a fixing 68 .

[0038] A second receiving groove 69 is provided inside the rotating shaft 61, and the clamping assembly 62 includes a movable member 610 slidably connected to the inner wall of the second receiving groove 69. Two symmetrically arranged second sliding grooves 611 are provided inside the end of the movable member 610 away from the rotating shaft 61. A second extruding member 612 is slidably connected inside each second sliding groove 611, and a second elastic member 613 is connected between the side where the two second extruding members 612 are close to each other and the inner wall of the corresponding second receiving groove 69.

[0039] A sprocket 614 meshing with the chain 4 is fixedly connected to the outer wall of the limiting member 63 , and a connecting shaft 615 rotatably connected to the inner wall of the housing 1 is fixedly connected to one end of the limiting member 63 away from the clamping assembly 62 .

[0040] like Fig. 9 As shown, the outer wall of the movable part 610 is rotatably connected to the magnet part 616, and the magnetic poles of the magnet part 616 and the electromagnet 67 that are close to each other are arranged in the same manner. The outer wall of the limiting part 63 located at the bottom of the sprocket 614 is rotatably connected to the limiting plate 617, and a third elastic part 618 is connected between the limiting plate 617 and the magnet part 616. The third elastic part 618 is sleeved on the outside of the clamping assembly 62 and the limiting part 63.

[0041] The magnetic poles of the magnet 616 and the electromagnet 67 that are close to each other are arranged in the same manner, that is, like poles repel each other and opposite poles attract each other.

[0042] like Fig.10 As shown, two first limiting grooves 65 are provided and are symmetrically arranged on the inner wall of the first receiving groove 64. The bottom of the first receiving groove 64 is arranged in a wedge-shaped surface. When the electromagnet 67 is energized, the electromagnet 67 will generate a magnetic force, which can push the magnet member 616 to move in the direction away from the electromagnet 67, squeeze the third elastic member 618, and enable the clamping assembly 62 to enter the first receiving groove 64 and the first limiting groove 65. The rotation of the rotating shaft 61 can drive the limiting member 63 and the sprocket 614 to rotate synchronously.

[0043] The bottom of the first accommodating groove 64 is set in a wedge-shaped surface. When the movable part 610 moves into the first accommodating groove 64 and the first limiting groove 65, the two second extruding parts 612 can contact the wedge-shaped surface at the bottom of the first accommodating groove 64, and squeeze the two second extruding parts 612 to move in a direction close to each other, and squeeze the second elastic part 613. When the two second extruding parts 612 rotate inside the first accommodating groove 64, when the two second extruding parts 612 move to the position of the two first limiting grooves 65, the second elastic part 613 can be elastically reset, and the two second extruding parts 612 can enter the inside of the two first limiting grooves 65 respectively to achieve limiting fixation, thereby the rotating shaft 61 can drive the limiting part 63 and the sprocket 614 to rotate synchronously through the movable part 610 and the second extruding part 612.

[0044] Under normal conditions, that is, when the electromagnet 67 is not energized, the third elastic member 618 acts, the magnet member 616 can contact the electromagnet 67, the snap-fit ​​assembly 62 disengages from the first accommodating groove 64 and the first limiting groove 65, and the rotation of the shaft 61 cannot drive the limiting member 63 and the sprocket 614 to rotate synchronously. When the electromagnet 67 is energized, the electromagnet 67 will generate a magnetic force, which can push the magnet member 616 to move away from the electromagnet 67, squeeze the third elastic member 618, and enable the snap-fit ​​assembly 62 to enter the first accommodating groove 64 and the first limiting groove 65. The rotation of the shaft 61 can drive the limiting member 63 and the sprocket 614 to rotate synchronously.

[0045] The transmission gear 66 is in transmission connection with the transmission mechanism 3 , and the driving motor 2 can drive the transmission gear 66 to rotate through the transmission mechanism 3 .

[0046] It should be noted that when the electric window opener is opening and closing the window, the controller 7 can control the drive motor 2 and the electromagnet 67 to be energized and work. The electromagnet 67 is energized to generate magnetic force, which can push the magnet member 616 to move in the direction away from the electromagnet 67, squeeze the third elastic member 618, and enable the clamping assembly 62 to enter the first accommodating groove 64 and the first limiting groove 65. The drive motor 2 can drive the rotating shaft 61 and the transmission gear 66 to rotate through the transmission mechanism 3. The rotation of the rotating shaft 61 can drive the limiting member 63 and the sprocket 614 to rotate synchronously, and can drive the chain 4 to move, so as to realize the opening and closing of the window. When there are impurities and other foreign matter between the window frame and the window sash, the electric window opener is in the process of closing the window. When the window sash contacts the foreign matter, it will increase the resistance of the electric window opener when closing the window, and can overcome the elastic force of the first elastic member 524, so that the first extrusion member 523 moves out of the adjustment groove. 512 moves inside the extrusion groove 511 until the moving part 521 moves to the extreme position inside the extrusion groove 511. Under the action of the first elastic part 524, the moving part 521 can contact with the corresponding pressure sensor 55, generate a detection signal, and transmit it to the controller 7. The controller 7 can control the drive motor 2 and the electromagnet 67 to cut off the power and stop working. When the drive motor 2 and the electromagnet 67 are powered off and stop working, the third elastic part 618 elastically resets, the magnet part 616 can contact with the electromagnet 67, and the clamping assembly 62 is disengaged from the first accommodating groove 64 and the first limiting groove 65. The rotation of the rotating shaft 61 cannot drive the limiting part 63 and the sprocket 614 to rotate synchronously, thereby avoiding the influence of the transmission mechanism 3. By pulling the handle of the window, the chain 4 can only drive the sprocket 614 to rotate, thereby realizing manual operation of opening and closing the window and improving practicality.

[0047] When the electric window opener is not in use, the drive motor 2 and the electromagnet 67 are both kept in a power-off state, which is convenient for manual operation of opening and closing the window.

[0048] In summary, the drive assembly 6 of the present invention is set up, when the electric window opener is working, the controller 7 can control the drive motor 2 and the electromagnet 67 to be powered on, and the electromagnet 67 is powered on to generate magnetic force, which can push the magnet member 616 to move in the direction away from the electromagnet 67, squeeze the third elastic member 618, and enable the clamping assembly 62 to enter the first accommodating groove 64 and the first limiting groove 65. The drive motor 2 can drive the rotating shaft 61 and the transmission gear 66 to rotate through the transmission mechanism 3, and can drive the limiting member 63 and the sprocket 614 to rotate synchronously. The rotation can drive the chain 4 to move, and the window can be opened and closed. When the driving motor 2 and the electromagnet 67 are powered off and stop working, the third elastic member 618 is elastically reset, and the magnet member 616 can contact the electromagnet 67. The clamping assembly 62 is disengaged from the first accommodating groove 64 and the first limiting groove 65. The rotation of the rotating shaft 61 cannot drive the limiting member 63 and the sprocket 614 to rotate synchronously, thereby avoiding the influence of the resistance of the transmission mechanism 3. By pulling the handle of the window, the window can be manually opened and closed, thereby improving the intelligence level of the window opener.
