Description

Technical Field

[0001] The utility model relates to the technical field of electronic display devices, and particularly relates to a multifunctional digital photo frame. Background Technique

[0002] Traditional photo frames are used by embedding printed photos. At present, with the improvement of living conditions and technological level, the use of digital photo frames is becoming more and more common. Digital photo frames can easily replace the displayed photos and have various functions such as rotating display according to settings. However, at present, the display screen and the component box of the digital photo frame are integrally formed. Because the display screen is always on and the internal components work, a large amount of heat is generated, and the heat dissipation area is limited. Therefore, the heat dissipation performance of the entire digital photo frame is poor during use. In addition, traditional digital photo frames always remain in a high-brightness always-on state or a low-brightness always-on state. When there is no one in the room, the high-brightness always-on state will cause a large amount of power consumption, and when the external light is bright and there are people in the room in the low-brightness always-on state, the images in the photo frame cannot be better displayed. For this reason, we propose a multifunctional digital photo frame. Summary of the Utility Model

[0019] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0020] Embodiment 1:

[0021] As Figures 1-5 shown, a multifunctional digital photo frame includes an LCD screen 1 and a component box 2. The component box 2 is movably installed on the rear surface of the LCD screen 1. A human body sensor 3 is fixedly installed near the middle position of the upper surface of the front surface of the LCD screen 1. A screen heat sink 4 is fixedly installed on the rear surface of the LCD screen 1. A component heat sink 7 is fixedly installed on the upper surface of the component box 2. A locking groove 6 is opened near the rear surface position of the upper surface of the component box 2. A folding and fixing structure 5 is fixedly installed in the locking groove 6. A magnetic attraction structure 8 is fixedly installed at the connection between the LCD screen 1 and the component box 2. A plug-in and control panel 9 is fixedly installed on one side surface of the component box 2;

[0022] A flexible cable 102 is fixedly installed on the rear surface of the LCD screen 1. The LCD screen 1 is electrically connected to the component box 2 through the flexible cable 102. Hinges 101 are fixedly installed on both sides of the flexible cable 102 on the rear surface of the LCD screen 1. The LCD screen 1 is movably installed with the component box 2 through the hinges 101; The magnetic attraction structure 8 includes an adsorption metal sheet 801 and a neodymium magnet 802. The adsorption metal sheet 801 is fixedly embedded and installed below the hinge 101 on the rear surface of the LCD screen 1. The neodymium magnet 802 is embedded and installed on the front surface of the component box 2. The adsorption between the adsorption metal sheet 801 and the neodymium magnet 802 can firmly adsorb and fix the LCD screen 1 on the front surface of the component box 2 in a 60-degree inclined state without external force; The front surface and the lower surface of the component box 2 are inclined 60 degrees backward, and the adsorption metal sheet 801 and the neodymium magnet 802 are arranged in a matching manner; The folding and fixing structure 5 includes a locking pin 501, a return spring 502, a dial 503 and a locking hook 504. One end of the return spring 502 is fixedly connected to the inside of the locking groove 6. The other end of the return spring 502 is connected to the locking pin 501. A dial 503 is fixedly installed on the surface of the locking pin 501. The locking hook 504 is fixedly installed on the rear surface of the LCD screen 1; The locking hook 504 and the locking pin 501 are arranged in a matching manner. When the LCD screen 1 and the component box 2 are folded, the screen heat sink 4 is embedded into the gap between the component heat sinks 7, and then the locking hook 504 is embedded into the locking groove 6 to squeeze the locking pin 501 to contract, and then the locking pin 501 is snapped into the card slot of the locking hook 504 under the elastic force of the return spring 502 to lock the LCD screen 1.

[0023] It should be noted that the present utility model is a multifunctional digital photo frame. When in use, the toggle piece 503 is toggled to compress the return spring 502 of the locking pin 501, so that the locking pin 501 disengages from the card slot on the locking hook 504. At this time, the LCD screen 1 can be turned up upward under the rotation of the hinge 101. When it is turned up to a certain angle, the adsorption metal sheet 801 on the LCD screen 1 is adsorbed and fixed by the neodymium magnet 802. At this time, the power cord can be plugged into the power supply hole on the plug-in and control panel 9 to charge the lithium battery inside the component box 2. At the same time, the power switch is turned on. Then, the user can insert a memory card or import a picture file for display. During the display, the human body sensor 3 constantly detects whether a human body exists. When a human body is detected, the single-chip microcomputer increases the current supplied to the LCD screen 1 to increase its brightness, thereby improving the display clarity of the photo album. When a person leaves for three minutes, the single-chip microcomputer restores the current supplied to the LCD screen 1 to the original current, thereby reducing the energy consumption of the LCD screen 1 and achieving the effect of energy conservation.
