Detailed Description

Referring to fig. 1 to 3, the utility model discloses an electric window, including window form 100, window 200 and electric window opener 300, the upper side of window 200 is articulated with window form 100, and electric window opener 300 includes control circuit and chain 310, control circuit includes motor, motor control module, MCU, current detection module and rotational speed detection module;

a motor: the driving chain 310 stretches;

In use, when electronic ware 300 of windowing is closing the window, motor operating current is directly proportional with output torque, the output torque of simultaneous working changes along with the change of motor resistance again, when the ware of windowing is when closing the in-process clip object of window, will certainly require the motor to overcome more resistance, the more electric current of needs just can maintain the balance of motion, therefore, in case press from both sides the foreign matter at the in-process of closing the window, inside motor speed can slow down, the current value that detects simultaneously can rise, therefore, utilize rotational speed detection module and current detection module to detect the change of the rotational speed that the motor takes place when pressing from both sides the foreign matter and electric current respectively, thereby feed back to MCU, and then through MCU driving motor reversal, make window 200 keep away from the foreign matter, guarantee that window 200 can not press from both sides the foreign matter and lead to window 200 damaged.

In addition, different resistances can make the current when closing the window different, and the resistance and the current are in a linear relation, and the current when clamping hands in the MCU can be used as the current limit value of the reference, and when clamping hands between the window 200 and the window body 100, the MCU can timely drive the motor to reversely rotate, so that the injury can be effectively prevented from continuing.

As a modification of the above technical solution, one end of the chain 310 extending out of the electric window opener 300 is hinged with the window 200. When the chain 310 pushes the window 200 to open, an included angle is formed between the chain 310 and the window 200, the included angle changes with the opening or closing of the window 200, and the chain 310 is hinged to the window 200, so that the chain 310 can be kept to interfere with the outlet of the electric window opener 300.

As a further improvement of the technical scheme, the rotating speed detection module comprises a Hall sensing device arranged in the motor. The Hall sensing device can transmit the detected rotating speed of the motor to the MCU.

Preferably, a hinge block 311 is fixed at one end of the chain 310 extending out of the electric window opener 300, and two sides of the hinge block 311 are disposed on the latch 3111; a mounting bracket 312 is fixed to a bottom side of the window 200, a recess is formed in the mounting bracket 312, slots are formed in both side edges of the recess, and the latch 3111 is inserted into the slots and can rotate therein. The hinge of the chain 310 to the window 200 is achieved by the rotation of the latch 3111 in the slot.

Preferably, the electric window opener 300 is fixed on the window 100.
