Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1

[0025] Please see Figure 1-7A digital photo frame includes a housing 100. The front of the housing 100 has a first recessed mounting position 110, through which a middle frame 200 is engaged. A digital display screen 112 is installed inside the middle frame 200. The back of the housing 100 has a second recessed mounting position 120, through which a back cover 300 is engaged. The inner side of the back cover 300 has multiple magnet mounting slots 310, inside which magnets 320 are embedded. A mainboard mounting position 330 inside the back cover 300 houses a control mainboard 340. Speakers 360 are installed in the two speaker mounting positions 350 of the 300. A groove 370 is provided on the back of the back cover 300, which is directly opposite the control motherboard 340. A wire passage groove 380 is provided on one side and the bottom of the groove 370. Two sound holes 390 are provided on the back of the back cover 300, which is directly opposite the two speakers 360. A type-C port 371 and a DC power port 372 are provided on the inside of the groove 370. The type-C port 371 and the DC power port 372 are respectively opposite to the type-C socket and the DC power socket of the control motherboard 340.

[0026] Specifically, during the process of assembling and using the digital photo frame daily, the outer shell 100 serves as the basic carrier of the overall structure. Its first recessed mounting position 110 on the front provides a precise mounting space for the middle frame 200. After the middle frame 200 is embedded in the first recessed mounting position 110, its internal digital display screen 112 can stably support the display function, allowing users to clearly view the content. After the front assembly is completed, the second recessed mounting position 120 on the back of the outer shell 100 will engage with the back shell 300. The magnet 320 embedded in the magnet mounting groove 310 on the inner side of the back shell 300 can provide a magnetic attraction effect.

[0027] To attach a picture frame to a metal object such as a refrigerator, users simply need to place the back cover 300 facing the metal surface. The magnet 320 will then use magnetic attraction to quickly fix the frame in place without any additional tools. The motherboard mounting position 330 on the back cover 300 will precisely position the control motherboard 340, ensuring a stable electrical connection between it and the digital display screen 112 and the speaker 360. The two speaker mounting positions 350 on the back cover 300 will keep the speaker 360 in a fixed position, preventing vibration and displacement from affecting the sound effect.

[0028] When the user needs power or data transmission, the Type-C port 371 in the groove 370 on the back of the back cover 300 can be connected to the data cable, and the DC power port 372 can be connected to the adapter. The cable trays 380 on the side and bottom of the groove 370 will neatly store the cables and prevent them from getting tangled. The sound outlet 390 on the back of the back cover 300, which is directly opposite the speaker 360, allows the sound from the speaker 360 to be transmitted smoothly. Through specific mechanical design, the photo frame is stable and efficient from assembly to use.

[0029] In this embodiment: a screen cover 220 is installed on the outer side of the middle frame 200 through multiple connectors 210, and the edge of the screen cover 220 is embedded and snapped into the top of the first recessed mounting position 110.

[0030] Specifically, during the assembly and daily protection of the digital photo frame screen, the middle frame 200, as the direct load-bearing structure of the digital display screen 112, has multiple connectors 210 on its outer side that are securely connected to the screen cover 220. During assembly, the screen cover 220 is simply fixed to the outside of the middle frame 200 via the connectors 210, thus providing a protective barrier for the internal digital display screen 112. After the screen assembly is completed, the edge of the screen cover 220 is embedded and snapped into the top of the first recessed mounting position 110 on the front of the outer casing 100. This not only creates a seamless appearance between the screen cover 220 and the outer casing 100, but also prevents dust and water stains from entering the middle frame 200 and contacting the digital display screen 112 during daily use. At the same time, it buffers the impact of minor bumps from the outside, preventing direct damage to the digital display screen 112 and effectively extending its service life.

[0031] In this embodiment: a plurality of first elastic protrusions 111 are fixedly connected to the inner side of the first recessed mounting position 110, and the first elastic protrusions 111 are engaged with the first slot 230 provided on the outer side of the middle frame 200.

[0032] Specifically, when the user assembles the middle frame 200 and the outer shell 100, the multiple first elastic protrusions 111 on the inner side of the first recessed mounting position 110 on the front of the outer shell 100 will form a precise engagement with the first slot 230 on the outer side of the middle frame 200. In specific operation, the user only needs to align the middle frame 200 with the first recessed mounting position 110 and gently push it in. The first elastic protrusions 111 will undergo elastic deformation due to the compression of the middle frame 200. After the middle frame 200 is pushed to the corresponding position, the first elastic protrusions 111 will spring back and embed into the first slot 230 of the middle frame 200, completing the stable connection between the two. No screws or other tools are required, which greatly simplifies the assembly process and improves production or maintenance efficiency.

[0033] In daily use, when the user moves the digital photo frame, the engagement between the first elastic protrusion 111 and the first slot 230 can resist the risk of loosening caused by vibration, preventing the middle frame 200 from falling off the first recessed mounting position 110, and ensuring the stable installation of the digital display screen 112 inside the middle frame 200. Even if disassembly and maintenance are required after long-term use, the middle frame 200 can be gently pried, and the first elastic protrusion 111 can be deformed again to disengage from the first slot 230, achieving convenient disassembly and assembly, making the connection between the middle frame 200 and the outer shell 100 both firm and flexible.

[0034] In this embodiment: the inner side of the second recessed mounting position 120 is connected to a plurality of second elastic protrusions 121, and the second elastic protrusions 121 are engaged with the second slot 3110 provided on the outer side of the back shell 300.

[0035] Specifically, during the assembly and subsequent use of the back shell 300 and the outer shell 100, multiple second elastic protrusions 121 on the inner side of the second recessed mounting position 120 on the back of the outer shell 100 will form an efficient engagement with the second slot 3110 on the outer side of the back shell 300. When the user pushes the back shell 300 into the second recessed mounting position 120, the second elastic protrusions 121 will be squeezed by the edge of the back shell 300 to generate elastic contraction. When the back shell 300 is fully pushed into the fitting position, the second elastic protrusions 121 will return to their original shape and be inserted into the second slot 3110 of the back shell 300, quickly completing the stable docking of the two and eliminating the tedious steps of screw fixing.

[0036] In daily use, when the user attaches the photo frame to the refrigerator using the magnet 320 of the back cover 300, the back cover 300 will be subjected to the combined action of the adsorption force and its own weight. The engaging structure of the second elastic protrusion 121 and the second slot 3110 can limit the displacement of the back cover 300, prevent it from falling off from the second recessed mounting position 120, and ensure the stable installation of components such as the control motherboard 340 and the speaker 360 inside the back cover 300.

[0037] When it is necessary to inspect the internal components of the picture frame, simply pull the back cover 300 outwards. After the second elastic protrusion 121 deforms, it will disengage from the second slot 3110, making it easy to disassemble. This makes the disassembly and assembly of the back cover 300 both convenient and reliable.

[0038] In this embodiment, multiple reinforcing ribs 3120 are also fixedly connected inside the back shell 300, and the multiple reinforcing ribs 3120 are distributed in a diamond grid.

[0039] Specifically, during the assembly of the digital photo frame, the diamond-shaped mesh reinforcing ribs 3120 provide uniform support to the inner wall of the back shell 300, preventing the weight of the components from causing localized dents and deformations in the back shell 300, and ensuring the accuracy of the component installation position. In actual use, when the user attaches the photo frame to the side wall of the refrigerator using the magnets 320, the back shell 300 will be subjected to lateral adsorption force and longitudinal gravity. At this time, the diamond-shaped mesh reinforcing ribs 3120 can distribute the force to various areas of the back shell 300, preventing localized stress concentration that could lead to deformation. If the photo frame is accidentally bumped slightly, the reinforcing ribs 3120 can also buffer the impact force, reducing the degree of deformation of the back shell 300. This can improve the structural strength of the back shell 300 in multiple dimensions, and maintain its shape stability even after long-term use, providing a continuous and safe load-bearing environment for the internal components.

[0040] In this embodiment: triangular hanging holes 3130 are provided on the back of the back shell 300 in both the horizontal and vertical directions, and multiple bracket mounting holes 3140 are provided in the middle of the back of the back shell 300.

[0041] Specifically, when users do not want to use the magnet 320 for adsorption and choose to hang the frame, they can use the horizontal or vertical triangular hanging holes 3130 on the back of the back cover 300 to pass the hook through the corresponding triangular hanging holes 3130, depending on the direction of the installation space. The triangular structure can increase the stability after hanging and prevent the picture frame from falling off due to slight shaking. It is suitable for living room wall hooks and entryway hooks.

[0042] When users wish to place the photo frame on a flat surface such as a desktop or bedside table, they can use the multiple bracket mounting holes 3140 in the center of the back cover 300 to align and fix the matching bracket connectors. The layout of the multiple mounting holes can accommodate brackets of different heights and angles, meeting the user's needs to adjust the display viewing angle. After fixing the bracket through the bracket mounting holes 3140, the user can adjust the angle of the photo frame to obtain a comfortable view, making the photo frame suitable for various scenarios such as hanging and bracket placement, greatly improving the flexibility of use.
