Description

Technical Field

[0001] The utility model relates to the technical field of digital photo frames, in particular to an infrared sensing digital photo frame. Background Art

[0002] Digital photo frames are photo frames that display digital photos instead of paper photos. Usually, the camera's memory card is directly inserted to display the photos. It is suitable for families, various elegant places such as shopping malls, guesthouses, hotels, leisure centers, bars, cafes, corridors, etc.

[0003] Application No. 201220603635.7 discloses an infrared sensing digital photo frame. When the infrared radiation from the human body is focused on the detection element of the pyroelectric infrared sensor through the Fresnel lens, the sensor in the circuit will output a voltage signal, and then make the signal pass through a bandpass filter first. The upper cutoff frequency of the filter is 16Hz and the lower cutoff frequency is 0.16Hz. Since the detection signal voltage output by the pyroelectric infrared sensor is very weak (usually only about 1mV) and is a changing signal, and the Fresnel lens makes the output signal voltage in a pulse form (the frequency of the pulse voltage is determined by the moving speed of the object being measured, usually about 0.1 to 10Hz), the voltage signal output by the pyroelectric infrared sensor should be amplified. This design uses an integrated operational amplifier for two-stage amplification to obtain sufficient gain. When the sensor detects the infrared signal radiated by the human body and sends it to the window comparator after amplification, if the signal amplitude exceeds the upper and lower limits of the window comparator, the system will output a high-level signal; if there is no abnormality, it will output a low-level signal. The rising edge signal of the high and low level change signal is used as the trigger signal of the monostable circuit, and it is made to output a high level signal with a pulse width of about 10s. This pulse width signal is then used as the input control signal of the digital photo frame power on and off to enable the circuit to generate a control signal to realize the automatic power on and off function of the digital photo frame.

[0004] The digital photo frame uses an infrared sensor to sense infrared radiation from the human body to turn the digital photo frame on and off, which can better ensure that the digital photo frame automatically turns off when no one is around and automatically turns on when someone is around. However, the device lacks important supporting components for digital cameras, which makes it inconvenient to use. Therefore, an infrared sensing digital photo frame is needed. Utility Model Content

When the bolts are tightened to make the assembly plate fall off the assembly slot, it can be hung on the hook of the external wall through the buckle, which increases the diversity of the placement of the device.

[0011] As a further improvement of the above solution, the positioning mechanism includes a base, the base is fixedly connected to the bottom of the silicone rod, and an anti-slip pad is fixedly connected to the bottom of the base.

A switch button is slidably connected to the left side of the photo frame body, and an infrared sensor is fixedly connected to the front of the photo frame body.
