Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0032] Refer to the instruction manual appendix Figure 1 , Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 11An electronic device with a multifunctional expandable structure includes a screen assembly 1, a plug-in mechanism 2 fixedly connected to the outside of the screen assembly 1, a base 3 disposed on the outside of the screen assembly 1, and a support frame 4 fixedly connected between the screen assembly 1 and the base 3.

The box component 21 includes a square box 211, and a recess 212 is provided on the outer side of the square box 211; The plug-in / plug-out component 26 includes a moving component 261 and four orifice blocks 262. Each orifice block 262 is located inside a corresponding square hole 25. A square iron block 263 is fixedly connected to the outside of the orifice block 262. Four square iron blocks 263 are provided. An orifice block 264 is slidably connected to the inside of the orifice block 262. An HDMI connector 268 is slidably connected inside the orifice block 264. A U-block 265 is fixedly connected to the outside of the orifice block 264. A U-block 266 is fixedly connected to the outside of the orifice block 262. A hydraulic rod 267 is fixedly connected to the outside of the U-block 266. The output end of the hydraulic rod 267 is fixedly connected to the U-block 265.

[0034] In this embodiment, the specific implementation scenario is as follows: When the device uses equipment to replace manual insertion and removal of the HDMI connector 268, the hydraulic rod 267 is activated to move the U-block 265, which in turn moves the orifice-shaped block 264. The orifice-shaped block 264 moves to the inside of the orifice-shaped block 262, and simultaneously, the orifice-shaped block 264, along with the inner HDMI connector 268, aligns with the HDMI signal interface 12 for connection. When it is necessary to remove the HDMI connector 268, the hydraulic rod 267 is activated to move the U-block 265, which in turn slides the orifice-shaped block 264 into the inside of the orifice-shaped block 262, simultaneously resetting the HDMI connector 268. Then, with the help of the moving component 261, the HDMI connector 268 that needs to be used can be aligned with the signal interface for connection. Through the setting of the insertion and removal mechanism, the machine can replace manual frequent insertion and removal of the HDMI connectors of various hosts, saving time and effort, and is convenient and fast. In addition, during this process, the corresponding HDMI cable of the host can be accurately identified, avoiding the situation of connecting the HDMI interface to the wrong host.

At the same time, the connecting block 23 moves the square plate 24 and related structures out of the square enclosure 211. After the HDMI connector 268 is installed, hydraulic rod 22 is activated again to move the connecting block 23 upwards.

The output end of the hydraulic rod 281 is fixedly connected to the moving block 282. The outer side of the moving block 282 is provided with a groove 283 and a groove 284.
[0048] It should be noted that square hole 1 25 and square hole 27 are interconnected, and square hole 3 28 and square hole 27 are interconnected.
[0049] Refer to the instruction manual appendix Figure 2 The screen assembly component 1 includes a screen assembly, on which a pop-up camera 11, an HDMI signal interface 12, a side-mounted graphics card 13, and a protective cover 14 are installed. There are two HDMI signal interfaces 12.
[0050] It should be noted that, with Figure 1 For a normal viewing angle, the protective cover 14 is installed on the rear side of the screen assembly and the side-mounted graphics card 13. The pop-up camera 11 of the screen assembly can automatically adjust its height and can be connected to an external HDMI connector 168 and the side-mounted graphics card 13.

[0051] Refer to the instruction manual appendix Figure 3 The base component 3 includes a base frame 31, and the outer side of the base frame 31 is provided with a data reading module 32, a card reading module 33, a wireless charging module 34, an extended hard disk module 35, and a cover 36.
[0052] It should be noted that, with Figure 1For a proper viewing angle, the cover 36 is installed on the top of the data reading module 32, card reading module 33, wireless charging module 34, and expansion hard drive module 35. The data reading module 32 can read data from the HUB board, TEYP-C SD card, and USB, while the card reading module 33 can identify and read IC / ID cards. The wireless charging module 34 can charge external devices, and the expansion hard drive module 35 can be installed for reading.
[0053] In this embodiment, the specific implementation scenario is as follows: when the electronic device is used in conjunction with four host computers and requires accurate connection of the HDMI connector 268 cable, then... Figure 6 From a top-down perspective, the electrical components in the plug-in / plug-out mechanism 2 are uniformly controlled and used by the central control mechanism 214. When one of the two plug-in / plug-out components 26 on the left and one of the two plug-in / plug-out components 26 on the right are needed, hydraulic rod five 281 is first activated, moving block 282 closer to square plate 24. Then, one of the two hydraulic rods two 2611 on the left is activated, and hydraulic rod two 2611 moves the corresponding electromagnet block one 2612 to adhere to the square iron block 263 of the corresponding orifice block one 262. Then, electromagnet block one 2612 is energized to firmly attract the square iron block 263. Then, hydraulic rod two 2611 moves orifice block one 262 and related structures into square hole two 27 until the square iron block 263 behind orifice block one 262 slides into slide groove two 271. At this time, hydraulic rod three 2613 on the left is activated, moving electromagnet block two 2614 closer to the left side of orifice block one 262. The square iron block 263 on the side is then de-energized, and the electromagnet block 2612 is energized. The square iron block 263 on the right side of the orifice block 262 is then slid into the groove 283 and stopped moving. At this time, the hydraulic rod 267 is activated, and the hydraulic rod 267 moves the U-block 265. The U-block 265 moves the orifice block 264. The orifice block 264, with the HDMI connector 268, passes through the recess 212 of the square box 211 and is inserted into the HDMI signal interface 12. Similarly, the HDMI connector 268 of one of the hosts on the right side can be inserted into the HDMI signal interface 12. At the same time, the night vision wide-angle camera 213 records the route during this process. When it is necessary to change the connection of different hosts, the plug-in component 26 must be reset first before connecting the required host. This can prevent the wires from getting tangled.
[0054] When the operator needs to use two plug-in components 26 on the same side, for example, if the two plug-in components 26 on the left side are needed, first move the first plug-in component 26 on the left. This will move the first plug-in component 26 on the left into the square hole 27. Then, the hydraulic rods 2613 on both sides, along with the electromagnet blocks 2614, will be energized to attract the square iron blocks 263 on both sides of the orifice block 262. The plug-in component 26 will then be moved to the right side of the square hole 27. The electromagnet blocks 2614 on the left will then be de-energized. Afterwards, the hydraulic rod 281 will be activated, moving the moving block 282 into the square hole 27 and approaching it. Then, the... The electromagnet block 2614 on the right side moves the plug-in component 26, and slides the square iron block 263 on the left side of the orifice block 264 into the groove 284. At the same time, the square iron block 263 on the right side of the orifice block 264 of the other plug-in component 26 is slid into the groove 283. Then the host HDMI connector 268 is connected. The movement and use of the plug-in component 26 require the cooperation of the night vision wide-angle camera 213 and the central control mechanism 214. The night vision wide-angle camera 213 and the central control mechanism 214 can be displayed on the screen assembly for easy use by the staff.
[0055] When the HDMI connector 268 is installed and used for the first time, the hydraulic rod 22 will be activated to move the connecting block 23. The connecting block 23 will move the square plate 24 and related structures out of the square housing 211. Then, the plugging and unplugging component 26 will be activated to move the orifice block 264 out. Then, the end away from the HDMI cable connector will be passed through the inside of the orifice block 264, through the inside of the orifice block 262, and through the side of the U-block 265. Then, the HDMI connector 268 will be installed into the inside of the orifice block 264, and the locking block 2682 will be installed into the locking slot 2681. The orifice block 264 is designed to be flexible, and the size of the locking slot 2681 is set to be only slightly smaller than the locking block 2682, so that the locking block 2682 can be clamped and fixed, preventing the HDMI connector 268 from easily moving out of the inside of the orifice block 264.
[0056] Working principle: When the electronic device is in use, the lifting camera 11 in the screen assembly 1 can be adaptively adjusted and can be used with an external side-mounted graphics card 13. The data reading module 32 and card reading module 33 in the base 3 can read relevant cards and can be used with a wireless charging module 34 to charge external devices. The electronic device can be used with an external expansion hard drive module 35. However, when connecting the HDMI signal interface 12 to the HDMI connector 268 of the host, the plug-in mechanism 2 can be used in conjunction.
[0057] 2. When four hosts are connected for use, first install the four HDMI connectors 268 inside the plug-in component 26. When two hosts need to be used, turn on the night vision wide-angle camera 213 in the cabinet component 21, record the movement route of the plug-in component 26, and transmit the relevant data to the central control mechanism 214. Then start the plug-in component 26 to use the HDMI connectors 268.
[0058] 3. When it is necessary to change different hosts to connect to the HDMI signal interface 12, use the plug-in component 26 to unplug the HDMI connector 268, and then reset it according to the previous movement route inside the central control mechanism 214. This can avoid the situation where the HDMI connector 268 cables of the four hosts are tangled together, and then two hosts are needed for use.
[0059] 4. When the HDMI connector 268 cable is frequently damaged and needs to be replaced, first activate the hydraulic rod 22 to move the square plate 24 and related structures out of the square box 211. Then, use the plug-in mechanism to replace the connector cable. After that, reset the square plate 24 and related structures.
[0060] The above embodiments are merely illustrative of several implementation methods of the present invention, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
