Abstract
The utility model discloses a multifunctional vehicle-mounted power supply converter. The utility model mainly comprises a host machine and a power plug, wherein the host machine is composed of a high frequency oscillating circuit, a rectifier and filter circuit, an inversion oscillating circuit, a changeover switch and a charging socket; the positive pole of the power plug is composed of a telescopic spring and a hardware contact pin, and the negative pole is composed of a stress spring and a set of at least three contact steel balls. The utility model can carry out changeover according to the different requirements of chargers of different electric appliances to operating currents and operating voltages to realize the multiple functions of the vehicle-mounted power supply converter and change the structure of power plugs of vehicle-mounted products to make the products tightly combined with a plug of a cigar lighter in order for hard looseness or hard fall; the utility model has the advantages of convenient application and safety.
Description
Technical field
The utility model relates to a kind of vehicle power transducer, especially a kind of multi-functional vehicle power transducer.
Background technology
Along with progress of science and technology, the consumer products that people use when driving is increasing, as digital camera, Digital Video, mobile phone, laptop computer, MP3 player or the like.And existing automobile generally is that output voltage is the automobile cigarette lighter socket of 12V for the power supply that the consumer products charging provides, and to the different requirements of electric current and voltage, power supply changeover device must be realized multifunction when charging in order to satisfy various consumer products.And existing vehicle power converter output voltage is single, uses very inconvenience.The plug that existing simultaneously vehicle power transducer is connected with the automobile cigarette lighter socket, its negative pole is to form at the arc sheet metal of two rubber-likes of plug column side face, after plug inserts cigarette lighter socket, lean on the elasticity and the socket inwall jam-packed of arc sheet metal to fix product.When running into that vehicle jolts or arc sheet metal elasticity when relatively poor, product is easy to loosening or comes off.
Summary of the invention
The purpose of this utility model is that development a kind ofly overcomes above-mentioned shortcoming, and a kind of multi-functional vehicle power transducer is provided.
The utility model mainly comprises: main frame and attaching plug two parts.Wherein, main frame is made up of high-frequency oscillating circuits, current rectifying and wave filtering circuit, inversion oscillating circuit, change over switch, charging socket; The positive pole of attaching plug is made up of a coil tension spring and a five metals contact stud, and negative pole has at least three to contact steel ball and form by a stress spring with one group.It is characterized in that: after the utility model attaching plug is inserted the automobile cigarette lighter socket, the positive pole of cigar lighter contacts with the five metals contact stud, the inwall negative pole of cigar lighter has at least three to contact the steel ball contact with one group, steel ball is subjected to the inwall squeezing action in stress spring, make the utility model cigarette lighter socket be difficult for combining closely becoming flexible or coming off, thus energized.Automobile cigarette lighter is the 12V DC power supply, and after the high-frequency oscillating circuits in main frame boosted and current rectifying and wave filtering circuit carries out filtering, exportable 300V direct current can connect the Switching Power Supply charger through charging socket and charge to electrical appliance; If increase the inversion oscillating circuit on this basis the 300V direct current is carried out 50HZ inversion vibration, promptly export the 220V alternating current, can connect various small-powers through charging socket and charge and charge to electrical appliance.An output change-over switch is set between current rectifying and wave filtering circuit and inversion oscillating circuit, can carries out the output conversion of 300V direct current or 220V alternating current at different chargers, thereby realize vehicle power transducer multifunction.
The novel beneficial effect of this reality is: can change the difference requirement of operating current, voltage according to the charger of different electrical appliances, realized the multifunction of vehicle power transducer, and changed the structure of vehicle-mounted product attaching plug, product can more be combined closely with cigarette lighter socket and be difficult for loosening or come off, conveniently be suitable for, safe and reliable.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further set forth, the utility model mainly comprises: host A and attaching plug B two parts.Wherein, host A is made up of high-frequency oscillating circuits, current rectifying and wave filtering circuit, inversion oscillating circuit, change over switch A2, charging socket A1; The positive pole of attaching plug B is made up of a coil tension spring B2 and a five metals contact stud B1, and negative pole has at least three to contact steel ball B3 and form by a stress spring B4 with one group.It is characterized in that: after the utility model attaching plug B is inserted the automobile cigarette lighter socket, the positive pole of cigar lighter contacts with five metals contact stud B1, the inwall negative pole of cigar lighter has at least three to contact steel ball B3 contact with one group, steel ball is subjected to the inwall squeezing action in stress spring B4, make the utility model cigarette lighter socket be difficult for combining closely becoming flexible or coming off, thus energized.Automobile cigarette lighter is the 12V DC power supply, and after the high-frequency oscillating circuits in host A boosted and current rectifying and wave filtering circuit carries out filtering, exportable 300V direct current can connect the Switching Power Supply charger through charging socket A1 and charge to electrical appliance; If increase the inversion oscillating circuit on this basis the 300V direct current is carried out 50HZ inversion vibration, promptly export the 220V alternating current, can connect various small-powers through charging socket and charge and charge to electrical appliance.An output change-over switch A2 is set between current rectifying and wave filtering circuit and inversion oscillating circuit, can carries out the output conversion of 300V direct current or 220V alternating current at different chargers, thereby realize vehicle power transducer multifunction.
