Utility model content

The utility model provides an intelligent mirror, which not only has the function of the most original mirror, meets the daily basic needs of users, but also can provide other practical functions for users.

The smart mirror of the present utility model comprises a semi-transparent mirror; a display unit located behind the semi-transparent mirror; an infrared sensing unit for sensing the distance between the human body and the mirror surface; an audio playback unit for playing sound; an instruction input unit for instructions; and a control unit for controlling the display unit, the infrared sensing unit, the audio playback unit and the instruction input unit.

Further, the smart mirror also includes a temperature sensor and a humidity sensor controlled by the control unit.

Further, the display unit is used to display the time data generated by the real-time clock control unit inside the control unit.

Further, the display unit is composed of LED light-emitting matrix point light sources.

Further, the display unit includes a decoder, a main LED dot matrix, an LED spectrum display driver chip and a spectrum LED dot matrix, and the control unit controls the main LED dot matrix through the decoder, and the control unit The unit controls the spectrum LED dot matrix through the LED spectrum display driving chip.

Further, the smart mirror includes a communication unit connected to the control unit for receiving external signals.

Further, when the audio playback unit is in the playback state, the control unit switches the display unit to an LED spectrum display mode to present a dynamic picture that dances with the music.

Further, when the infrared sensing unit senses that the distance between the human body and the mirror is within a predetermined range, the control unit turns off the display unit.

The smart mirror provided by the utility model senses the distance between the human body and the mirror through the infrared sensing unit. When the human body is close to the mirror, the display unit does not work, which is a normal mirror function; when the infrared sensing unit does not sense the human body within the predetermined range When no one looks in the mirror, the display unit operates according to the preset program of the control unit, which can display temperature, humidity and time, and can also play audio according to the signal of the communication unit. In this way, the mirror provides more practical functions for the user.

detailed description

As shown in Figure 1, the utility model provides a kind of intelligent mirror, comprises semi-transparent mirror (not shown); The display unit B that is positioned at the rear of semi-transparent mirror; The infrared sensor unit that is used for sensing the distance between human body and mirror surface C; an audio playback unit D for playing sound; an instruction input unit E for inputting instructions; and a control unit A for controlling the display unit B, the infrared sensing unit C, the audio playback unit D and the instruction input unit E.

As shown in Figure 2, in one embodiment, the control unit A of the smart mirror includes a single-chip microcomputer as a core component; the display unit B is composed of LED light-emitting matrix point light sources, including a decoder B1, a main LED dot matrix B2, an LED Spectrum display driver chip B3, spectrum LED dot matrix B4 and digital tube B5. The single-chip microcomputer controls the main LED dot matrix B2 through two cascaded decoders B1, and the single-chip microcomputer controls the spectrum LED dot matrix B4 through the LED spectrum display driver chip B3, so as to switch from the normal clock display mode to the LED spectrum display mode.

The single-chip microcomputer is connected to the temperature and humidity sensor F (including the temperature sensor and the humidity sensor), and displays the data of the temperature and humidity sensor F through the digital tube B5. When the display unit B is turned on, the pattern displayed by the main LED dot matrix B2, or the pattern displayed by the spectrum LED dot matrix B4, or the temperature and humidity displayed by the nixie tube B5 can be observed in front of the half mirror. And when the display unit B is not lit, what is seen from the outside is a mirror.

In one embodiment, the infrared sensing unit C is an infrared distance sensor, which includes an infrared receiving tube and an infrared emitting tube. The single-chip microcomputer is connected to the infrared receiving tube and the infrared emitting tube. The single-chip microcomputer controls the infrared emitting tube to continuously emit infrared light signals, and at the same time controls the infrared receiving tube to monitor the infrared light signals. If an object is close to the mirror, the infrared light signal reflected by the object will be received by the infrared Tube capture, at this time the single chip will turn off the display unit B.

When the infrared distance sensor does not receive the infrared light signal, it means that the user is far away from the mirror. At this time, the main LED dot matrix B2 in the mirror lights up and displays the current time. The time data can be generated by the internal real-time clock control unit (RTC) of the single-chip microcomputer. Or generated by an independent time unit; at the same time, the digital tube B5 displays the temperature and humidity read by the microcontroller from the temperature and humidity sensor F.

When the user approaches the mirror within a predetermined range (for example, 50 centimeters), the infrared distance sensor receives the infrared light signal, and the single-chip microcomputer controls the display unit B to go out. Due to the characteristics of the half-mirror, when there is no light inside the frame, the half-mirror is just a reflecting mirror from the outside. At this time, the user can use the smart mirror as an ordinary mirror.

When using the Bluetooth of the mobile phone to connect to the communication unit G (such as a Bluetooth module) of the smart mirror and play music, the smart mirror will automatically switch from the ordinary clock display mode to the LED spectrum display mode. The audio signal, and perform fast Fourier transform on the audio signal to obtain the real-time spectrum of the audio signal, and then display it through the spectrum LED dot matrix B4, and become an LED light column that dances with the music, which has great ornamental value. In addition, the audio playback unit D is composed of an audio power amplifier, a loudspeaker and a buzzer; the audio signal of the Bluetooth module is played through the loudspeaker after being processed by the audio power amplifier.

In one embodiment, the instruction input unit E is a touch button on the inner side of the top of the mirror frame, and the alarm clock and the clock can be set through the touch button. In normal clock display mode, the user can set the current clock through the hidden touch button on the top of the frame, and also set the alarm clock. It will flash and display the alarm clock pattern. At this time, you can turn off the alarm by gesture. The specific method is to wave your palm within the effective distance of the infrared distance sensor. After the smart mirror receives the gesture signal, it will display a smiling face and stop the alarm. For convenience, the smart mirror can be placed on a bedside table or on a table to turn off an alarm.

The beneficial effect of the utility model is that, on the premise of ensuring the normal use of the original mirror function, the functions of clock display, temperature and humidity display, alarm clock setting and gesture closing alarm clock, bluetooth speaker and ornamental LED music spectrum display are added, It is both practical and beautiful, adding a sense of beauty and technology.

The above is only a preferred embodiment of the present invention. Those skilled in the art may still make various replacements and modifications based on the teachings and disclosures of this creation. The protection scope of this creation It is not limited to the content disclosed in the embodiment, but should include various replacements and modifications that do not deviate from the invention, all of which are claimed in the claims of this patent application.
