Referring to
a surface cove 10, a surface cover plate 11, a frame body 12, a bottom case 13 and a back plate 14, wherein the lower surface of the surface cover 10 is detachably fixed with the upper end of the frame body 12, a waterproof adhesive tape is arranged on the periphery of the lower surface of the surface cover 10, the upper surface of the surface cover 10 is fixed with the surface cover plate 11 by injection molding, the lower end of the frame body 12 is fixed with the upper surface of the bottom case 13 by injection molding, the lower surface of the bottom case 13 is fixed with the upper surface of the back plate 14 by injection molding, the corresponding end of the frame body 12 is fixed with an adaption interface 20 by injection molding (for better description, the adaption interface 20 is separately shown in
As shown in
The protective housing further comprises a protective circuit. As shown in
Furthermore, the negative input end of the comparator is grounded, the positive input end of the comparator is connected with a pin of the outer side of the adaption interface 20, the output end of the comparator is connected with the base electrode of the triode T, the collector electrode of the triode T is connected with the U+ interface of a USB interface of the display device, the emitter electrode of the triode T is connected with one end of a coil JQ of the relay J, the other end of the coil JQ is connected with one end of a protective resistor R1, and the other end of the protective resistor R1 is grounded, a pin of the inner side of the adaption interface 20 is further connected with one end of a switch JK1 of the relay, and the other end of the switch JK1 is connected with a pin of the inner side.
The working principle of the above protective circuit is as follows: in normal working, since the pin of the outer side is connected with the host, this pin is of high level; at this moment, the comparator outputs a high level, T is conducted, JQ is electrified, JK1 is closed, and the pin works normally; when the display device is placed in water, since the exposed pin of the outer side is grounded through water at such time, this pin is of low level; at this moment the positive input end and the negative input end of the comparator are basically of the same level, the comparator outputs a low level, then T is turned off, JQ is powered off and JK1 is opened, such that the pin of the inner side of the adaption interface 20 is disconnected from the pin of the outer side, avoiding that the display device is connected at this time to cause a short circuit of the multiple pins of the first connector and cause an impact on the display device.
Preferably, the protective circuit may further include an inductor L, one end of the inductor L is connected with the other end of the switch JK1, and the other end of the inductor L is connected with a pin of the inner side of the adaption interface.
The inductor L is added so as to solve the following problem: when the display device just contacts water, the voltage changes suddenly and an impulse voltage is generated; however, by this time, the comparator probably has not yet responded and JK1 is still closed; if the pin of the outer side and the pin of the inner side are directly connected at this moment, an impact will be caused on the display device, thereby damaging the display device. Therefore, the addition of the inductor L can inhibit the impulse voltage and provide a protection for the display device. In addition, in normal working, since the current and the voltage are relatively stable, the inductor L equals a short circuit, which causes no impact on the display device.
Preferably, the protective housing further includes a surface cover protective film 15, and the surface cover protective film 15 is arranged between the surface cover 10 and the frame body 12. The surface cover protective film 15 provides certain protection for the display screen of the display device.
Preferably, the lower surface of the back plate 14 is fixed with a rotating device, which includes a base 30, a rotating handle 31 and a hand strap 32. The base 30 is provided with a spindle nut 301, the rotating handle 31 is provided with a rotary screw 311 corresponding to the spindle nut 301, and the hand strap 32 is fixed onto both ends of the rotating handle 31.
The arrangement of the rotating device may allow the user to conveniently adjust the angle for holding the display device, so that it is convenient for the user to watch the display device.
The present application further provides a notebook computer. The notebook computer includes a display device and a host, wherein the display device is provided with the protective housing according to the present application.

Specific examples are adopted in this disclosure to illustrate the principle and implementation of the present application.
