[0026] Please see Figure 4-5 The bottom of the tray 3 is provided with a bottom groove 301, and the top of the inner cavity of the bottom groove 301 is provided with a slot 302. A first magnet 303 is embedded and fixedly connected to the top of the inner cavity of the bottom groove 301. A base plate 304 is rotatably connected inside the bottom groove 301. A second magnet 305 is embedded and fixedly connected to the upper surface of one end of the base plate 304. An inner groove 306 is provided on the upper surface of the base plate 304. A support arm 307 is rotatably connected inside the inner groove 306. A spring 308 is fixedly connected between the support arm 307 and the base plate 304. An anti-slip pad 309 is fixedly connected to the bottom of the base plate 304. One end of the tray 3 is rotatably connected to one end of the base plate 304. The first magnet 303 and the second magnet 305 are magnetically attracted to each other. The support arm 307 is movably engaged in the slot 302.
[0027] By setting the bottom groove 301, the slot 302, the base plate 304 and the support arm 307, the portable device body 1 can be tilted and supported to improve the user comfort and heat dissipation space. The slot 302 can provide support and limit at different angles for the portable device body 1. By setting the first magnet 303 and the second magnet 305, the first magnet 303 and the second magnet 305 can be magnetically fixed after the base plate 304 is retracted into the bottom groove 301 to prevent the base plate 304 from automatically falling out.
[0028] Working principle: When the ultra-thin KVM ruggedized portable computer is in use, in the initial state, the touchpad 101 and keyboard 103 are first fixed on the portable computer body 1. The display screen 104 is rotatably connected to the rear end of the portable computer body 1 to facilitate normal use of the portable computer. KVM-VGA interface 2, KVM-PS / 2 interface 201, KVM switch 202 and KVM indicator light 203 are respectively provided on the left side and the left side of the upper surface of the portable computer body 1. KVM module is also provided inside the portable computer body 1 to enable KVM function expansion. The base plate 304 is rotatably connected to the tray 3 fixed at the bottom of the portable computer body 1. The support arm 307 rotatably connected to the base plate 304 is snapped into the slot 302 to tilt and support the portable computer body 1 to improve the comfort of use and heat dissipation.
[0029] When it is necessary to enable the portable computer body 1 to perform multiple functions using KVM, the video signal of the motherboard inside the portable computer body 1 and the signal connected to the external KVM-VGA interface 2 are first switched and selected by the KVM module to be finally displayed on the screen. The KVM module also switches whether the signals of the keyboard 103 and the touchpad 101 go to the motherboard or to the external keyboard and mouse signal cable. By introducing a serial port module and flexibly using the serial port, multiple functions can be achieved with one port.
