Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model is an external touch screen, including a touch screen body 100, a protective cover 200 disposed on the front of the touch screen body 100, and a mounting component 300 disposed on the back of the touch screen body 100.

[0031] The touch screen body 100 includes a front housing 101 and a rear housing 102 disposed opposite to each other. A screen 101d is sealed and embedded in the middle position of the front housing 101, and a magnetic groove 101e is provided on the front edge of the front housing 101.

[0032] The protective cover 200 includes a cover plate 201 movably connected to the front edge of the front housing 101 via a shaft, and a magnetic block 202 fixed to the inner edge of the cover plate 201. The cover plate 201 covers the screen 101d, and the magnetic block 202 fixed to the inner side of the cover plate 201 cooperates with the magnetic groove 101e provided on the front edge of the front housing 101. The cover plate 201 can be flipped open or closed like a book page, which allows users to quickly access the screen 101d as needed, and also provides effective physical protection for the screen 101d. The magnetic block 202 cooperates with the magnetic groove 101e. When the cover plate 201 is closed, the magnetic force improves the closing stability of the cover plate 201, thereby protecting the screen 101d.

[0033] The mounting assembly 300 includes a positioning ball shell 301 fixed to the outside of the rear housing 102, a ball joint connector 303 movably disposed inside the positioning ball shell 301, and a mounting plate 304 fixed to the end of the ball joint connector 303. The mounting plate 304 serves as the component that is finally fixed to an external structure (such as a desktop stand, wall, etc.). Its connection with the ball joint connector 303 ensures that a stable installation state can be maintained even after the angle is adjusted. After the positioning ball shell 301 is freed from the constraint of the positioning knob 302, it can move freely relative to the ball joint connector 303 for adjusting the angle of the touch screen body 100.

[0034] Specifically, the front housing 101 and the rear housing 102 are sealed together, and the bottom of the rear housing 102 is provided with heat dissipation grooves 102b at equal intervals, which helps natural convection and thus conducts heat from the inside to the outside. The bottom corner of the rear housing 102 is recessed to provide an interface area 102a, and the interface area 102a is provided with multiple types of interfaces, such as USB, HDMI or other universal interfaces, to facilitate users to connect external devices or power supplies. The centralized interface layout simplifies wiring and makes the appearance cleaner. The positioning ball shell 301 is threadedly fitted with a positioning knob 302 on its side, and the inner end of the positioning knob 302 is fixed to the circumference of the ball head connector 303. The positioning knob 302 is used to lock the ball head connector 303 and the positioning ball shell 301, thereby fixing the angle of the touch screen body 100.

[0035] Furthermore, a button 101a is provided at the lower edge of the front of the front housing 101 for easy user operation, and a speaker 101b is provided at the middle of the lower edge of the front of the front housing 101 for providing audio output. A camera 101c is embedded at the middle of the upper edge of the front of the front housing 101, enabling the touch screen to support visual recognition or video recording functions. The camera 101c, button 101a, speaker 101b, and screen 101d are all connected to the circuit board inside the front housing 101 via internal wires and PCB traces to ensure the stability and reliability of signal transmission.

[0036] The operation process in this embodiment is as follows:

[0037] Fix the installation plate 304 to the selected installation position, adjust the working angle of the touch screen body 100, and after adjusting the angle, use the positioning knob 302 to lock the current position. Then connect the power cord and the required external devices, such as USB devices and HDMI video sources, through the multiple types of interfaces in the interface area 102a.

[0038] When ready to use the touchscreen, gently flip open the magnetic protective cover 200, press the button 101a at the lower edge of the front of the front housing 101 to activate the touchscreen, use the built-in camera 101c for video calls or visual recognition tasks, and obtain audio output through the speaker 101b.

[0039] If you need to adjust the angle of the screen 101d, loosen the positioning knob 302, adjust it to the appropriate angle, and then tighten the positioning knob 302 to fix it. Once the device is started and adjusted to the satisfactory angle, you can use the touch screen for interactive operation.

[0040] After use, press button 101a again to turn off the device. To protect the screen 101d, close the protective cover 200 when not in use and ensure that the magnetic block 202 is attached to the magnetic slot 101e.
