Description
Technical field
The utility model relates to a kind of charger, in particular, relates to a kind of onboard charger with safety hammer with elastic safety hammer.
Background technology
In the prior art, day by day universal along with portable type electronic product, the various function supporting with electronic product and the charger of model also produce thereupon.Onboard charger is a kind of power supply unit automobile storage battery power supply (general voltage is 12V or 24V) being converted to can charge for the electronic product such as mobile phone, GPS (general voltage is 5V).The positive pole that existing car fills adopts the five metals spring being located at housing forward end central authorities to be connected with the positive pole of automobile storage battery, and negative pole is connected with automobile storage battery negative pole to multiple five metals shell fragment by be located at housing side two.The shortcoming that above-mentioned car fills is that the just as easy as rolling off a log and both positive and negative polarity of automobile storage battery that car fills when automobile bumpiness gets loose, and contact bad, positive pole and negative pole take larger space in addition, make the space in housing less.
Summary of the invention
Technical purpose of the present utility model is the unicity overcoming onboard charger function, onboard charger is designed to can with the instrument of safe escape, the structure overcoming onboard charger also exists and easily gets loose and the technical problem of loose contact, a kind of both positive and negative polarity is provided to take up room little, and space in housing is large, and possesses the onboard charger with safety hammer of safety hammer for escape function.
For realizing above technical purpose, the technical solution of the utility model is:
With the onboard charger of safety hammer, include a buckle-type USB interface lid, buckle-type USB interface covers and is provided with USB interface, the below of described buckle-type USB interface lid is provided with an aluminum alloy casing, the top inner circumferential of described aluminum alloy casing is provided with the upper draw-in groove corresponding with buckle-type USB interface lid, the both sides, periphery of described aluminum alloy casing are provided with the negative electrode contiguous block connecting automobile charger negative electrode, described negative electrode contiguous block connects usb circuit, a buckle-type insulating washer is provided with in the below of described aluminum alloy casing, buckle-type insulating washer periphery is provided with outer buckle, inner circumferential below described aluminum alloy casing is provided with the lower bayonet slot corresponding with buckle-type insulating washer, buckle-type insulating washer inside circumference is provided with interior buckle, described interior buckle is arranged with slip safety hammer, described slip safety hammer periphery is provided with the sliding tray mated with interior buckle, slip safety hammer connects the positive electrode of automobile charger, slip safety hammer connects usb circuit.
Further, be provided with spring groove in described slip safety hammer, in described spring groove, be provided with spring, one end top pressure spring trench bottom of spring, the block in the other end top jewelling alloy shell of spring.
Advantageous Effects of the present utility model is: all accessories of product adopt buckle structure design, time saving and energy saving in the production assembling time; Cost of labor is reduced while enhancing productivity.Have as safety hammer effect in the application, need can play during emergency escape in car break vehicle glass into pieces and obtain chance for survival; The spring assembly Telescopic safety hammer inside established, not easily get loose when contacting positive pole power-off.
Accompanying drawing explanation
Fig. 1 is that the quick-fried of the utility model embodiment tears structural representation open.
Fig. 2 is the product structure schematic diagram of the utility model embodiment.
Fig. 3 is the structure enlarged diagram of slip safety hammer and periphery thereof.
Embodiment
Composition graphs 1, Fig. 2 and Fig. 3, describe embodiment of the present utility model in detail, but be not limited in any way claim.
In the structure of the utility model with the onboard charger of safety hammer, special construction design can puncture vehicle glass rapidly, and onboard charger front end positive pole selects special steel material and distinctive appearance structural design, can pound rapidly the instrument wearing vehicle glass escape.Include a buckle-type USB interface lid 100, buckle-type USB interface lid 100 is provided with USB interface, the below of described buckle-type USB interface lid 100 is provided with an aluminum alloy casing 101, the top inner circumferential of aluminum alloy casing 101 is provided with the upper draw-in groove corresponding with buckle-type USB interface lid 100, the both sides, periphery of aluminum alloy casing 101 are provided with the negative electrode contiguous block 102 connecting automobile charger negative electrode, described negative electrode contiguous block 102 connects usb circuit, the below of aluminum alloy casing is provided with a buckle-type insulating washer 103, buckle-type insulating washer 103 periphery is provided with outer buckle, inner circumferential below aluminum alloy casing 101 is provided with the lower bayonet slot corresponding with buckle-type insulating washer 103, buckle-type insulating washer 103 inside circumference is provided with interior buckle, described interior buckle is arranged with slip safety hammer 104, described slip safety hammer 104 periphery is provided with the sliding tray 112 mated with interior buckle, slip safety hammer 104 connects the positive electrode of automobile charger, described slip safety hammer 104 connects usb circuit.Be provided with spring groove 110 in described slip safety hammer 104, be provided with spring 105 in described spring groove 110, one end of spring 105 is provided with the bottom of spring groove 110, the block in the other end top jewelling alloy shell 101 of spring 105.Meanwhile, in buckle-type insulating washer 103, spring eye 111 is provided with; Spring 105 can enter in aluminum alloy casing 101 through spring eye 111.Specifically see Fig. 3, sliding tray 112 coordinates with spring 105 can be made slip safety hammer 104 complete to slide and reset.
