AI Technical Summary

Technical Problem

Existing electric window openers cannot lock themselves after the window is opened to a certain angle, making them susceptible to being pushed by external forces and changing the angle, thus failing to stably maintain the window in the open state.

Method used

The system employs a ratchet and ratchet tooth structure. When the motor is not working, the ratchet tooth is tightened by a tension spring to hold the ratchet tooth in place, thus achieving self-locking. When the motor starts, the limit pin pushes the linkage sleeve to unlock the ratchet tooth, allowing the drive shaft to rotate and controlling the window opening angle.

Benefits of technology

It achieves self-locking when the motor is not working, stably maintaining the window opening angle, and allows the motor to drive the window to open and close normally when needed.

[0034] Embodiment one:

[0035] As Figures 1 to 6The utility model discloses a window opener window stroke control mechanism, including the rectangular casing, the motor 1 of fixed in the casing and the rotation installation in the bottom of casing's pivot 2, the one end fixed mounting of pivot 2 that stretches out the casing has a lever 3, and lever 3 is used for connecting the slider on the slide rail installed on the window.Electric motor 1 can connect external power supply.When electric motor 1 works, electric motor 1 can make pivot 2 rotate, and through lever 3 drives the slider to move in the slide rail, realizes the control to the window opening angle.

[0037] In order to be able to lock the transmission shaft 4 when electric motor 1 does not work, the utility model is fixed with ratchet wheel 7 on transmission shaft 4, and is fixed a mounting plate 9 in casing simultaneously, and is installed two ratchet teeth 8 on mounting plate 9, and ratchet tooth 8 can rotate. Figure 6 As Figure 6 The utility model discloses a window opener window stroke control mechanism, including the rectangular casing, the motor 1 of fixed in the casing and the rotation installation in the bottom of casing's pivot 2, the one end fixed mounting of pivot 2 that stretches out the casing has a lever 3, and lever 3 is used for connecting the slider on the slide rail installed on the window.Electric motor 1 can connect external power supply.When electric motor 1 works, electric motor 1 can make pivot 2 rotate, and through lever 3 drives the slider to move in the slide rail, realizes the control to the window opening angle.

[0038] When two ratchet teeth 8 all resist on ratchet wheel 7, ratchet tooth 8 will hold ratchet wheel 7, makes ratchet wheel 7 unable to rotate, and then realizes the locking of transmission shaft 4 and pivot 2.

[0039] The utility model discloses a window opener window stroke control mechanism, including the rectangular casing, the motor 1 of fixed in the casing and the rotation installation in the bottom of casing's pivot 2, the one end fixed mounting of pivot 2 that stretches out the casing has a lever 3, and lever 3 is used for connecting the slider on the slide rail installed on the window.Electric motor 1 can connect external power supply.When electric motor 1 works, electric motor 1 can make pivot 2 rotate, and through lever 3 drives the slider to move in the slide rail, realizes the control to the window opening angle.

[0040] As Figure 5As shown, the transmission part specifically comprises an inclined surface arranged at one end of the linkage sleeve 12 close to the motor 1 and a protrusion 20 fixed on the inclined surface. A spring 14 is arranged on the transmission shaft 4 between the linkage sleeve 12 and the ratchet wheel 7. When the motor 1 is not started, the output shaft of the motor 1 can rotate, and under the action of the spring 14, the deepest part of the inclined surface abuts against the limiting column 13. When the motor 1 is started, the output shaft rotates, and because there is a certain resistance in pushing the window to open, the limiting column 13 does not immediately drive the linkage sleeve 12 to rotate when it starts to rotate, but changes the contact position with the inclined surface, pushes the inclined surface, so that the linkage sleeve 12 compresses the spring 14 and moves on the transmission shaft 4, until the limiting column 13 abuts against the protrusion 20, the limiting column 13 cannot continue to drive the linkage sleeve 12 to move, but drives the linkage sleeve 12 to rotate.

[0041] As shown in the drawings, Figure 5 The linkage sleeve 12 is fixed with a disc 19, the housing is fixed with a guide rail, the unlocking block 15 is slidingly installed on the guide rail, and the sliding direction of the unlocking block 15 on the guide rail is parallel to the transmission shaft 4. The disc 19 is located on the side of the unlocking block 15 away from the mounting plate 9. The unlocking block 15 is provided with a driving slope. The unlocking frame 11 is arranged on the mounting plate 9 in a lifting manner, and the unlocking frame 11 is provided with a guide slope matched with the driving slope. When the linkage sleeve 12 compresses the spring 14, the disc 19 pushes the unlocking block 15 to move towards the unlocking frame 11, the driving slope pushes the guide slope, so that the unlocking frame 11 moves downward. Two pawls 8 are fixed with a push plate 16, and the push plate 16 is located below the unlocking frame 11, when the unlocking frame 11 moves downward and pushes the push plate 16, the pawl 8 overcomes the tension of the tension spring 10 and rotates away from the ratchet wheel 7, so as to be separated from the ratchet wheel 7 and the unlocking state of the transmission shaft 4 is released.

[0042] Example two:

[0043] On the basis of example one, considering that the motor 1 cannot be started when the power at home is off, the motor 1 cannot release the locking state of the transmission shaft 4, so that the user cannot open the window. Therefore, the utility model is screwed on the housing with an unlocking column 17. As shown in the drawings, Figure 3 One end of the unlocking column 17 protrudes out of the housing, and the other end of the unlocking column 17 is movably inserted into the unlocking frame 11. One side of the unlocking frame 11 is attached to the mounting plate 9. In this way, the unlocking frame 11 cannot rotate, but can only move up and down along the unlocking column 17. The unlocking column 17 is provided with a limiting flange 18, when the unlocking column 17 moves downward, the limiting flange 18 pushes the unlocking frame 11 to move downward.

[0044] When the motor 1 cannot be used, the user can rotate the unlocking column 17 to drive the unlocking column 17 to move downward, and the limiting flange 18 presses the unlocking frame 11, so that the unlocking frame 11 presses the push plate 16, and the pawl 8 is separated from the ratchet wheel 7, and the transmission shaft 4 is unlocked. In this way, the user can manually open the window.

[0045] Example three:

[0046] On the basis of example one and example two, the battery 21 can be fixedly installed in the casing, and the motor 1 is powered by the battery 21. The battery 21 can be used as a backup power source, and when the home power is off, the motor 1 is driven to work by using the battery 21.

[0047] Obviously, various modifications and changes can be made to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and changes fall within the scope of the present application claims and their equivalents, it is intended to include such modifications and changes in the present application.
