[0028] The driving bar 41 can drive the driving column 411 to slide in the chute 311 at one end of the hinged rod 31 of the parallel hinge 3, so as to drive the parallel hinge 3 to expand and contract, so as to open or close the window sash 2, and at the same time, the window sash 2 can be locked when the window sash 2 is closed, without adding an electric lock, and the failure rate is reduced at the same time.

[0029] There is no limit to the number of the parallel hinges 3 in this embodiment, as long as multiple parallel hinges 3 can enable the window sash 2 to translate stably, so as to stably open or close the window sash 2. In order to make the window sash 2 open or close more stably, in this embodiment, it is preferably that both the left and right sides and the upper and lower sides of the window frame 1 and the window sash 2 are connected by the parallel hinges 3. Such a design can make the window sash 2 open or close more stably.

[0030] It should be noted that chutes 311 are provided on the hinged rods 31 of the parallel hinges 3 on both the left and right sides, the driving bars 41 are two and are respectively slidably installed on the two driving slide rails 42, and the two driving slide rails 42 are respectively installed on the left and right sides of the window frame 1.

[0031] The chute 311 includes an arc portion and a straight portion provided at one end of the arc portion. When the window sash 2 is opened, the driving column 411 can enter from the straight portion into the arc portion to drive the parallel hinge 3 to expand and contract and open the window sash 2. When the window sash 2 is closed, the driving column 411 can enter from the arc portion into the straight portion to close the window sash 2 and lock the window sash 2 at the same time.

[0032] In this embodiment, the driving bar 41 is connected to the threaded sleeve 43. A lead screw 44 is threadedly connected to each of the threaded sleeves 43. One end of the lead screw 44 is drivingly connected to an electric driving device 46 through a first belt 45. A corner transmission is installed on the lead screw 44, and the corner transmission is drivingly connected to a manual driving device 49 through a second belt 48. The electric driving device 46 can drive the two lead screws 44 to rotate. The lead screw 44 can drive the driving bar 41 to slide in the driving slide rail 42 through the threaded sleeve 43. At the same time, the driving column 411 can slide in the chute 311, so as to drive the parallel hinge 3 to expand and contract, so as to open or close the window sash 2. In case of power failure, the user can use the manual driving device 49. The manual driving device 49 can drive the lead screw 44 to rotate through the second belt 48 and the corner transmission, so as to open or close the window sash 2, which is timely and convenient.

[0033] It should be noted that there are two threaded sleeves 43, which are respectively connected to the two driving bars 41. A lead screw 44 is threadedly connected to each of the two threaded sleeves 43. One end of the two lead screws 44 is respectively drivingly connected to the electric driving device 46 through a first belt 45.

[0034] More specifically, as Figures 4-6 shown, the electric driving device 46 includes two first mounting plates 4601. The two mounting plates 4601 are installed in parallel on the window frame 1. A spring column 4602 is installed between the two first mounting plates 4601. A rotating column 4603 is installed on the spring column 4602. A first driving wheel 4604 is rotatably provided on the rotating column 4603. The first belt 45 is wound around the first driving wheel 4604. A first toothed ring 4605 is coaxially installed on the first driving wheel 4604. The first toothed ring 4605 meshes with a second toothed ring 4606. The second toothed ring 4606 is drivingly connected to a motor 4607. One end of the second toothed ring 4606 is connected to one end of a spring 4608. The other end of the spring 4608 is connected to the spring column 4602. The motor 4607 can drive the second toothed ring 4606 to rotate. The second gear 4602 can drive the first toothed ring 4605 to rotate. The first toothed ring 4605 can drive the first driving wheel 4604 to rotate, so as to drive the first belt 45 to rotate.

[0035] It should be noted that a first transmission wheel is installed at one end of each of the two lead screws 44. The first belt 45 is wound around the first driving wheel 4604 and the first transmission wheel.

[0036] Preferably, the two first mounting plates 4601 are connected through a connecting column 4609. A fixed wheel 4610 is installed on the connecting column 4609. The first belt 45 is clamped and connected between the first driving wheel 4604 and the fixed wheel 4610. The fixed wheel 4610 can increase the friction or tension between the first belt 45 and the first driving wheel 4604, so as to facilitate the first driving wheel 464 to drive the first belt (or chain) 45 to rotate.

[0037] Preferably, a guiding ring 4611 is coaxially installed on the second toothed ring 4606. The guiding ring 4611 is provided with guiding holes, and the connecting column 4609 is slidably arranged in the guiding holes 4611. Through the guiding ring 4611, the second toothed ring 4606 can move stably after being separated from the first toothed ring 4605, so that the structure of the electric driving device 46 can be more stable.

[0038] Preferably, a separating ring 4612 is coaxially installed on the guiding ring 4611. Tooth blocks 4613 are installed on the separating ring 4612. The tooth blocks 4613 are engaged with a gear 4614. The gear 4614 is rotatably installed on the second mounting plate 4615. The second mounting plate 4615 is installed on one side of the first mounting plate 4601. The gear 4614 is connected to one end of a connecting rod 4616. A fixing groove 46161 is provided at the other end of the connecting rod 4616. A fixing block 46151 is provided on the second mounting plate 4615. A fixing bolt 4617 that is in threaded connection with the fixing block 46151 and is matched with the fixing groove 46151 is provided in the fixing block 46151. When a power failure occurs, the connecting rod 4616 is rotated. The connecting rod 4616 can drive the gear 4614 to rotate. The gear 4614 can drive the separating ring 4612 to move through the tooth blocks 4613, so that the first toothed ring 4605 is separated from the second toothed ring 4606. Then, the position of the connecting rod 4616 is fixed by the fixing bolt 4617, so that the user can rotate the hand crank 492 more easily, and thus the user can conveniently manually open the window sash 2.

[0039] More specifically, as Figure 7 shown, the manual driving device 49 includes a second driving wheel 491 rotatably installed on the window frame 1. A second belt 48 is wound around the second driving wheel 491. The second driving wheel 491 is connected to the hand crank 492. By rotating the hand crank 492 by hand, the second driving wheel 491 can be driven to rotate. The second driving wheel 491 can drive the lead screw 44 to rotate through the second belt 48 and the angle transmission device. The lead screw 44 can drive the driving strip 41 to slide in the driving slide rail 42 through the threaded sleeve 43. At the same time, the driving column 411 can slide in the sliding groove 311, so as to drive the parallel hinge 3 to expand or contract, so as to open or close the window sash 2. The structure is simple and the operation is convenient.

[0040] It should be noted that the angle transmission device includes two meshing bevel gears. One of the bevel gears is installed on the lead screw 44, and the other bevel gear is connected to the second transmission wheel. The second belt 48 is wound around the second driving wheel 491 and the second transmission wheel.

[0041] In this embodiment, a control button for controlling the motor 4607 is installed on the hand crank 492. The motor 4607 can be controlled through the control button, so as to control the opening or closing of the window sash 2.

[0042] It should be noted that the control buttons include a window-opening button 493, a stop button 494, and a window-closing button 495. The window sash 2 can be respectively controlled to open, stop moving, or close through the window-opening button 493, the stop button 494, and the window-closing button 495.

[0043] Specific principle: When it is necessary to open or close the window sash 2, the window-opening button 493 or the window-closing button 495 is opened. The second toothed ring 4606 can be driven to rotate by the motor 4607. The first toothed ring 4605 can be driven to rotate by the second toothed ring 4606. The first driving wheel 4604 can be driven to rotate by the first toothed ring 4605. The lead screw 44 can be driven to rotate by the first driving wheel 4604 through the first belt 45. The driving bar 41 can be driven to slide in the driving slide rail 42 by the lead screw 44 through the threaded sleeve 43. At the same time, the driving column 411 can slide in the chute 311, so as to drive the driving column 411 to unlock. After unlocking, the parallel hinge 3 expands and contracts to open or close the window sash 2. When a power failure occurs, the connecting rod 4616 is rotated. The gear 4614 can be driven to rotate by the connecting rod 4616. The separating ring 4612 can be driven to move by the gear 4614 through the tooth block 4613, so that the first toothed ring 4605 is separated from the second toothed ring 4606. At the same time, the position of the connecting rod 4616 is fixed by the fixing bolt 4617. After the fixing is completed, the hand crank 492 is rotated. The lead screw 44 can be driven to rotate by the hand crank 492 through the second belt 48 and the corner transmission device. The driving bar 41 can be driven to slide in the driving slide rail 42 by the lead screw 44 through the threaded sleeve 43. At the same time, the driving column 411 can slide in the chute 311, so as to drive the parallel hinge 3 to expand and contract to open or close the window sash 2.
