POWER SAVING TYPE VEHICLE SOCKET APPARATUS

Abstract

A power saving type vehicle socket apparatus includes a housing, a circuit board, a power conversion circuit, a power socket, a magnetic switch, a shroud and a magnetic object. The housing includes a tube opening. The shroud includes a cap. When the cap caps the tube opening of the housing, the magnetic switch senses the magnetic object to generate a first signal to send the first signal to the power conversion circuit, so that the power conversion circuit stop supplying power to the power socket. When the cap does not cap the tube opening of the housing, the magnetic switch does not sense the magnetic object, so that the magnetic switch generates a second signal to send the second signal to the power conversion circuit, so that the power conversion circuit supplies power to the power socket.

[0033] FIG. 3 shows a schematic diagram that the power saving type vehicle socket apparatus of the present invention supplies power. FIG. 4 shows a schematic diagram that the power saving type vehicle socket apparatus of the present invention does not supply power. Please refer to FIG. 1, FIG. 2 and FIG. 5 at the same time.

[0034] When the cap 33 caps the tube opening 11 of the housing 1, the magnetic switch 28 senses the magnetic object 34 to generate a first signal Si to send the first signal Si to the power conversion circuit 21, so that the power conversion circuit 21 stop supplying power to the power socket 22. When the cap 33 does not cap the tube opening 11 of the housing 1, the magnetic switch 28 does not sense the magnetic object 34, so that the magnetic switch 28 generates a second signal S2 to send the second signal S2 to the power conversion circuit 21, so that the power conversion circuit 21 supplies power to the power socket 22.

[0035] Moreover, the power conversion circuit 21 is, for example but not limited to, a direct-current-to-direct-current converter to convert a voltage of a battery (not shown in the figures) into a voltage which is supplied to the power socket 22. The power conversion circuit 21 has the overload protection and the over-temperature protection. The power socket 22 is, for example but not limited to, a universal serial bus connector. The magnetic object 34 is, for example but not limited to, a ring permanent magnet. The shroud 3 is, for example but not limited to, made of light-passing materials. The positive-negative-electrode transposition protecting component 402 is, for example but not limited to, a diode.

The voltage regulator 406 is used to supply power to the magnetic sensor 408. The electromagnetic interference filter circuit 410 is used to filtering electromagnetic interference. A diameter of the through hole 162 is slightly smaller than an outside diameter of the electric lead 23 to block fluids or dusts. When the power conversion circuit 21 supplies power to the power socket 22, the power conversion circuit 21 supplies power to the light-emitting component 26 to drive the light-emitting component 26 to light to remind the user. The flange 12 and the rotary knob 14 can together clamp a vehicle.

[0036] The advantage of the present invention is that when the power saving type vehicle socket apparatus 5 is not used and the cap 33 caps the tube opening 11 of the housing 1, the power conversion circuit 21 stops supplying power to the power socket 22 to save power. Moreover, the shroud 3 protects the power socket 22, so that the power socket 22 is not broken easily. Moreover, the positive-negative-electrode transposition protecting component 402 is used to avoid incorrectly inversely connecting to the battery. Moreover, the power conversion circuit 21 has the overload protection.
