Description

The invention relates to a drive mechanism for sash, and in particular to a device for automatically opening and closing window and door blocks, in particular, to the design of the device with the possibility of remote control.

It is known to open and close the installation device, which contains a hidden hinge, a first connecting part, a second connecting part and a connecting rod assembly, wherein the first connecting part is provided with a first guide groove, the second connecting part is provided with a second guide groove, the connecting rod assembly contains a first connecting rod and a second connecting rod, one the end of the first connecting rod is pivotally connected to the first connecting part, the other end of the first connecting rod is provided with a first guide part matched with the second guide groove, one end of the second connecting rod is pivotally connected to the second connecting part, and the other end of the second connecting rod is provided with a second guide part matched with the first guide groove (Patent No. CN210370296U. Publ. 2020-04-21).

However, the known device is mechanical and is not designed to automatically open window sashes with a remote control.

Known automatic device for opening and closing windows, containing a feed gear, which is respectively mounted on both sides of the upper window frame, a toothed belt, which is attached to the feed gear and circulates in a circular orbit through the feed gear, one end is connected to a toothed belt, and the other end is a connecting part connected to the upper part of the window and transported together with the window, and a rotational part of the toothed belt, applying a rotational force to the transmission gear to rotate the toothed belt in one direction or the other direction and the window connected to the toothed belt (Patent No. KR102076822 . Publ. 2020-02-12).

However, the known device, despite the fact that it contains a mechanical transmission controlled by the controller, moves the window sashes relative to each other, and is not intended for automatic opening of the window sashes.

A fully automatic smart window is known comprising a window frame, a sash, a blocker, a locking rod, a locking bolt, and one opposite side of the window frame and the sash are connected through a hinge; an automatic locking device is located on one side provided with a locking rod; a device for automatic opening and closing of the lock are connected to the lock rod and set the lock rod in motion; the automatic opening and closing device is installed in the window frame, and the automatic opening and closing device is connected to the window sash through a rocker and drives the window sash for opening and closing. In addition, it has two motors connected to the clutch mechanisms (Patent No. CN210563812U. Publ. 2020-05-19).

However, in the known automatic smart window, the movement mechanisms are installed in the window frame, which reduces its strength and durability, increases the dimensions of the window frame and sash.

Known automatic device for opening or closing a window, which includes: a drive motor provided on any of at least one pair of window units; a drive roller rotatable on the same centerline with a vertical shaft that rotates by power supplied from a drive motor and engages one surface of an adjacent lifting sliding window block at its outer periphery to slide open and close the window unit, while the driving roller is connected in such a way as to slide along the axial direction of the vertical shaft using the sliding means so that the driving roller rises integrally with the lifting sliding window block, which rises to a predetermined height with the guide in the time of the opening or closing operation (Patent No. RU2664212. Publ. 15.08.2018).

However, the known automatic device is designed to open and close window blocks with the possibility of smooth sliding of one relative to the other in the right and left directions, and not for automatic opening of the window blocks one relative to the other. It also has complex mechanics.

There is a known mechanism for closing windows and doors, in which the rolling element is driven along the axial line of the main sliding guide, causing the roller attached to the rolling element to forcefully act on one or the other side of the groove in the operating element. The working element at one end thereof is pivotally attached to the main sliding guide so as to drive the second sliding guide by means of a slider pivotally mounted on the outer end of the working element. The centerline of the main sliding guide and the centerline of the groove in the working element intersect at a constant acute angle. In the case when the rolling element is equipped with a spring that creates a constant tension away from the pivot point of the working element, this spring forces the closing device to close automatically (Patent No. RU2180937. Published 03/27/2002).

However, the known device has a complex structure and does not have the ability to be remotely controlled.

Known automatic device for opening windows, containing an electric motor with a gearbox, an opening-closing mechanism connected at one end with the output shaft of the gearbox, a power supply and an electronic unit including a digital temperature sensor, a processor, in addition, it is inserted into an electronic unit connected to the processor carbon dioxide sensor, Wi-Fi module, transistor keys, components for power supply, controls and displays, while the device is made with the possibility of a variable operating mode from information about the measured temperature or carbon dioxide content from the corresponding sensors, from information with a schedule of the exact opening time and closing, while the device is configured with an autonomous control panel (Patent No. RU181118. Publ. 04.07.2018).

However, the known device has a rather cumbersome structure, including a voluminous body, an arm protruding above the window block, and a rather laborious installation. In addition, the known device lacks the ability to work from micro USB, control via an IR remote control, and work in a “smart home” system with any events and sensors.

The task is to expand the arsenal of technical means designed for automatic opening of windows and doors.

The technical result of the proposed solution is compactness and small dimensions of the structure, the possibility of saving space during installation and reducing the labor intensity of installation, the ability to easily tilt the device for its repair, expanding the control channels of the device.

This result is achieved by the fact that in a device for opening windows and doors containing a body, an electric motor, an actuator, an electric current source, interconnected microelectronic components, in which the body is pivotally connected to an actuator made in the form of a lever, which is equipped with an electric motor connected to moving element, while the latter is equipped with a carriage installed with the possibility of longitudinal movement and rotation by means of a movable connection relative to the bracket, an electric current source is installed in the housing, made in the form of a reusable or disposable power source, or a power connector, and a board on which a microcontroller is fixed connected to a power converter and an electric motor controller, in addition, the microcontroller is connected to the charge controller, IR receiver, control button, RGB LED, in addition, the microcontroller has the ability to control by radio channel.

It is advisable to obtain a smooth movement, the displacement element is made in the form of a stepping screw.

It is advisable to expand the range of use, the fastening element is in the form of a bracket.

It is advisable to use an electric motor with a built-in gear to increase the efficiency of the device.
