[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] Before explaining the embodiments of the present application in detail, the application scenarios of the embodiments of the present application are first described.

[0042] Please also read Figures 1 to 11 Now, a window opening and closing control device provided by an embodiment of the present application is described. The window opening and closing control device comprises: a housing 10 , a first transmission rod 11 , a first motor 12 and a first circuit board 13 .

[0043] The first transmission rod 11 is movably mounted on the side of the housing 10, the first motor 12 is fixedly mounted inside the housing 10, the first motor 12 can drive the first transmission rod 11 to move, thereby causing the window blades connected to the first transmission rod 11 to open and close, and the first circuit board 13 is mounted inside the housing 10, the first circuit board 13 is used to control the operation of the first motor 12. Specifically, the first circuit board 13 includes an MCU control unit 131, a communication unit 132, a Hall chip unit 133, a motor drive chip unit 134 and an LDO buck unit 135; the communication unit 132 is electrically connected to the MCU control unit 131, the motor drive chip unit 134 is electrically connected to the MCU control unit 131 and the LDO buck unit 135 respectively, and the Hall chip unit 133 is electrically connected to the motor drive chip unit 134 to control the rotation angle of the first motor 12.

[0044] Specifically, by setting a Hall chip unit 133 on the first circuit board 13, the rotation angle of the first motor 12 can be controlled by the Hall chip unit 133, so as to control the opening and closing angle of the window leaf; there is no need to set up devices such as switches, which can prevent the problem of too many components occupying the housing 10, and also facilitate the wiring operation between the first motor 12 and the first circuit board 13; moreover, the first circuit board 13 can also be respectively arranged at the head and end of the housing 10 with the first motor 12, and there is no need to set them adjacent to each other, so that the layout is more flexible, and the size of the entire switch window control device can be further reduced, so that it is easy to be installed in a window frame with smaller space.

[0045] Preferably, the MCU control unit 131 includes a main control chip U5 of model APM32F003-20 and its peripheral circuits, the motor drive chip unit 134 includes a chip of model AT8236 and its peripheral circuits, and the Hall chip unit 133 includes a chip of model KTH5702 and its peripheral circuits.

[0046] In some embodiments of the present application, a first position 101 for installing a first motor 12 is provided at one end of the housing 10, a second position 102 for installing a first circuit board 13 is provided at the other end of the housing 10, a third position 103 for installing a transmission component is provided between the first position 101 and the second position 102, and the first position 101, the third position 103 and the second position 102 are arranged in sequence on the same straight line. Since the first motor 12 realizes angle encoding through the Hall chip unit 133, there is no need to use a travel switch, which not only reduces the number of wiring, but also allows the installation positions of the first circuit board 13 and the first motor 12 to be flexibly arranged.

[0047] The transmission component includes a clutch structure 14, a first reduction gear set 15, a connecting gear piece 16, a manual gear piece 17 and a second reduction gear set 18. The first reduction gear set 15 is meshed and connected with the first motor 12 and the clutch structure 14 respectively; the connecting gear piece 16 is meshed and connected with the first transmission rod 11, and the manual gear piece 17 is meshed and connected with the connecting gear piece 16; the second reduction gear set 18 is meshed and connected with the clutch structure 14 and the connecting gear piece 16 respectively. When the window leaf needs to be opened and closed automatically, the first motor 12 rotates, which can drive the first reduction gear set 15 and the connecting gear piece 16 to rotate, thereby driving the first transmission rod 11 to move, so as to open and close the window leaf; when the window leaf needs to be opened and closed manually, the manual gear piece 17 rotates, and the connecting gear piece 16 rotates, thereby driving the first transmission rod 11 to move, so as to open and close the window leaf; when the window leaf is opened and closed manually, due to the provision of the clutch structure 14, the first motor 12 will not be driven to rotate in the opposite direction, which can not only protect the motor, but also reduce the strength of the user to manually open and close the window leaf.

[0048] Preferably, the clutch structure 14 includes a first clutch tooth plate 141, a first magnetic plate 142, a first limiting column 143 and a second clutch tooth plate 144 arranged from top to bottom; a first clutch chamber 1411 is arranged at the bottom of the first clutch tooth plate 141, and a first limiting groove 1412 is arranged on the wall of the first clutch chamber 1411; the second clutch tooth plate 144 is provided with a second shift block 1441, and when the first clutch tooth plate 141 rotates, the second shift block 1441 can shift the first limiting column 143 into the first limiting groove 1412 to drive the second clutch tooth plate 144 to rotate synchronously. During assembly, first, the second shift block 1441 is fixedly installed on the second clutch tooth plate 144, so that the second shift block 1441 can rotate synchronously with the second clutch tooth plate 144; then, the first magnetic plate 142 is installed, so that the lower surface of the first magnetic plate 142 is against the upper surface of the second clutch tooth plate 144; then, the first limiting column 143 is placed on the upper surface of the first magnetic plate 142; finally, the first clutch tooth plate 141 is installed, so that the second shift block 1441 and the first limiting column 143 can enter the first clutch chamber 1411, and the first clutch tooth plate 141 can be rotated to make the second shift block 1441 move the first limiting column 143 to be stuck in the first limiting groove 1412.

[0049] Next, a magnet is disposed on the upper surface of the first magnetic attraction sheet 142, and the magnet is arranged in a ring shape, and the first limiting column 143 can be adsorbed by the magnet; when the second shift block 1441 cancels the force acting on the first limiting column 143, the magnet can adsorb the first limiting column 143 out of the first limiting groove 1412, so that the first limiting column 143 is not stuck in the first limiting groove 1412; with such a structure, when the window is manually opened and closed, the manual tooth piece 17 rotates to drive the connecting tooth piece 16 to rotate, and the first transmission rod 11 is transmitted During displacement, the first clutch tooth is simultaneously driven to rotate in the opposite direction via the connecting tooth plate 16, thereby causing the first limiting groove 1412 to rotate away from the second shift block 1441 and become misaligned. Once the second shift block 1441 cancels the force acting on the first limiting column 143, the first limiting column 143 will withdraw from the first limiting groove 1412 due to the suction force of the first magnetic sheet 142. At this time, even if the window is opened and closed manually, the motor will not be driven to reverse, thereby ensuring that the force required for manual opening and closing of the window is small and manual opening and closing is also easier.

[0050] In some embodiments of the present application, the first reduction gear set 15 includes a first reduction gear 151, a second reduction gear 152 meshed with the first reduction gear 151, and a third reduction gear 153 meshed with the second reduction gear 152. The rotating shaft of the first motor 12 is provided with a first worm 121 meshed with the first reduction gear 151, and the third reduction gear 153 is meshed and connected with the first clutch gear plate 141. The first reduction gear 151, the second reduction gear 152, and the third reduction gear 153 each include a large gear and a small gear. For example, the small gear of the first reduction gear 151 is meshed and connected with the large gear of the second reduction gear 152, and the small gear of the second reduction gear 152 is meshed and connected with the large gear of the third reduction gear 153.

[0051] It should be noted that the structure of the second reduction gear set 18 is substantially the same as that of the first reduction gear set 15 , both of which are for reducing speed and increasing torque, and will not be described in detail here.

[0052] Preferably, the first transmission rod 11 is movably mounted on the right side of the housing 10 , and a first protruding tooth 111 is provided on the side of the first transmission rod 11 facing the third bin 103 , and the engaging tooth piece 16 is meshedly connected with the first protruding tooth 111 .

[0053] In other embodiments of the present application, there are two first transmission rods 11, and both first transmission rods 11 are provided with a first transmission part 112, and a second convex tooth 113 is provided on a side opposite to the two first transmission parts 112; a first driven gear 104 is provided on the right side of the casing 10, and the first driven gear 104 is meshed with the second convex tooth 113; any first transmission rod 11 is provided with a first convex tooth 111, and after the connecting tooth piece is meshed and connected with the first convex tooth 111, when driving one first transmission rod 11 to move, the other first transmission rod 11 can be synchronously driven to move via the first driven gear 104, so that the two mirror-image-arranged double-opening window leafs can be synchronously opened and closed at the same time.

[0054] Preferably, the manual tooth piece 17 is provided with a first square hole 171 for the handle to be installed in. The first transmission rod 11 is provided with a first connecting protrusion 114, and the first connecting protrusion 114 is used to be inserted into the mounting hole of the window leaf.

These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way.
