Non-contact controlled dimming electronic window

This creation relates to an electronic window, and in particular to a non-contact controlled dimming type electronic window.

Taiwan's new patent announcement No. M501469 is a gesture-controlled vehicle electronic window and electronic window. The image recognition device directly captures images in the vehicle, and the controller uses image processing to identify the user according to the captured image. After the gesture action, the light transmittance of the electronic window unit is controlled accordingly. In this way, the user does not need to find a physical button switch or a remote controller when driving, thereby increasing the safety of driving and the convenience of operation.

However, when there is insufficient light in the car and in a dim state, such as at night or in a rainy day, insufficient ambient light source will make the image captured by the image recognition device appear dark and blurred, which makes it difficult for the controller to recognize in the image. The gesture action of the user is affected, thereby affecting the recognition rate, causing troubles such as malfunction or inability to dim.

Therefore, the main purpose of the present invention is to provide a non-contact-controlled dimming type electronic window, which can perform dimming control without capturing an in-vehicle image through an image recognition device, and naturally there is no disadvantage that the prior art is derived from an insufficient ambient light source.

The non-contact controlled dimming electronic window of the present invention comprises: a window body; a non-contact gesture sensor for being disposed in the vehicle, and generating a sensing signal according to the gesture motion of the user, the non-contact gesture sensor It is selected from the group consisting of a capacitive sensor, an infrared sensor and an ultrasonic sensor; a dimming device is coupled to the window body; and a controller electrically connected to the non-contact gesture sensor and the dimming device, and the sensing signal generated by the non-contact gesture sensor is transmitted through a power supply device The light transmittance of the dimming device is changed.

According to the present creation, the present invention senses a user's gestures by means of a capacitive sensor, an infrared sensor or an ultrasonic sensor. The sensors mainly generate different sensing signals according to different gesture actions, for example, when When the user's hand enters the sensing range of the capacitive sensor, the capacitive sensor can generate an inductive signal, so when the user waves his hand to make a gesture, the controller can change the tone according to the change of the sensing signal. Light transmittance of the optical device. Therefore, compared with the prior art, the present invention does not need to rely on the ambient light source, does not capture the image in the vehicle through the image recognition device, and does not perform image recognition through the image processing. Therefore, the prior art cannot overcome the low image recognition rate due to insufficient ambient light source. The disadvantage of dimming control.
