(5) embodiment

First embodiment

The utility model provides a kind of switching protective device, can prevent to open by mistake motor-driven work, please refer to the synoptic diagram according to a kind of switching protective device of first preferred embodiment of the present utility model shown in Fig. 2 A.

Portable computer 200 has a switch 210; be power switch; switch 210 is promoted then power supply opening; when switch 210 pushes back then power-off; the switch 210 outer protection rings 220 that are with; the switch 210 all sides that are arranged at described portable computer 200 are and surrounded with switch 210, and protection ring 220 is that C shape ring-type is lived switch 210 circles, and protection ring 220 can rotate.

Please refer to shown in Fig. 2 B according to the protection ring of a kind of switching protective device of first preferred embodiment of the present utility model synoptic diagram when the release position.Protection ring 220 has an opening 230, and when opening 230 rotated to release position 250, opening 230 was sitting at switch 210 and can promotes on the path this moment; then switch 210 can promote, by opening 230, opening power; switch 210 can also push back, and by opening 230, returns original position and shuts down computer.

Please refer to shown in Fig. 2 C according to the protection ring of a kind of switching protective device of first preferred embodiment of the present utility model synoptic diagram when the make-position.When opening 230 rotated to make-position 260, then switch 210 can't promote, by opening 230, and then can't opening power.So when the opening 230 of protection ring 220 rotates to make-position 260, just can protect power supply can not opened because of carelessness, switch 210 is protected in protection ring 220.And have above the protection ring 220 a plurality of salient points 240 around, this is in order to increase the friction force between protection ring 220 and the hand when rotating protection ring 220, when making us the application of force being rotated on protection ring 220, easier rotation.

Second embodiment

The utility model provides a kind of device of switch protection, can prevent error cut-off machine action, please refer to the synoptic diagram according to a kind of switching protective device of second preferred embodiment of the present utility model shown in Fig. 3 A.

Portable computer 300 has a switch 310, is power switch, and switch 310 is promoted then power supply opening, when switch 310 pushes back then power-off, is with protection rings 320 outside the switch 310, for C shape ring-type switch 310 circles is lived, and protection ring 320 can rotate.

Please refer to shown in Fig. 3 B according to the protection ring of a kind of switching protective device of second preferred embodiment of the present utility model synoptic diagram when the release position.Protection ring 320 has an opening 330, and when opening 330 rotated to release position 350, opening 330 was sitting at switch 310 and can promotes on the path this moment; then switch 310 can promote, by opening 330, powered-down; switch 310 can also push back, and by opening 330, gets back to original position and opens computing machine.

Please refer to shown in Fig. 3 C according to the protection ring of a kind of switching protective device of second preferred embodiment of the present utility model synoptic diagram when the make-position.When opening 330 rotated to make-position 360, then switch 310 can't promote, by opening 330, and then can't powered-down.So when the opening 330 of protection ring 320 rotates to make-position 360, just can protect power supply can not closed because of carelessness, switch 310 is protected in protection ring 320.And have above the protection ring 320 a plurality of salient points 340 around, this is in order to increase the friction force between protection ring 320 and the hand when rotating protection ring 320, when making us the application of force being rotated on protection ring 320, easier rotation.

In sum; first embodiment mainly can prevent to open by mistake motor-driven work; and second embodiment can prevent the error cut-off machine action; therefore feature of the present utility model is when protection ring rotates to the release position; could or close the power supply opening of computing machine; when the rotating closed position of protection ring, just can protect the mobile computer switch can not cause power supply opening or close because of running into because of carelessness, bump against, foundering.

Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the modification of the above embodiment.
