Description
The utility model relates to a kind of integral vehicular mobile phone charger with hand-free call function.
In the prior art, as No. 952183420, Chinese patent disclosed " automobile-used charger for mobile phone " with hand-free call function, it is made up of power supply plug body, charging Connection Block, microphone, loudspeaker, electric circuit board and flexible flexible cord, and the power supply plug body is the hollow housing that an end is provided with plug; Charging Connection Block one end is provided with the socket of band tie point; Electric circuit board is made up of power supply processing unit, logical signal switch, microphone amplifying circuit, loudspeaker amplifying circuit, connecting line and plate body, and microphone, loudspeaker are connected with microphone amplifying circuit, loudspeaker amplifying circuit through the logical signal switch respectively.Its power supply plug body is provided with flexible flexible cord with charging between the Connection Block, and only depends on fixedly mobile phone of plug and jack, and structure is complexity not too rationally and.The utility model also is to the further improvement of my " automobile-used mobile phone charger " (number of patent application is 992126207) and perfect.
The purpose of this utility model aims to provide a kind of simple in structure, compact, uses more convenient safe integral vehicular mobile phone charger, to overcome the prior art weak point.
A kind of integral vehicular mobile phone charger with hand-free call function by this purpose design comprises the charging plug and the charger body that link to each other with automobile power source, and described charging plug is active the connection with charger body; Charger body is provided with the fixedly detent mechanism and the cavity that circuit board and element thereof are set of mobile phone, and its architectural feature is also to be provided with earphone (or earplug) socket and speaker/earpiece change over switch on the described charger.
That described charging plug and charger body active is connected to is hinged, ratchet location or bolt adjusting knob are connected.Described charger body top is provided with the fixedly groove of mobile phone, and groove is provided with snap lock and links closely; The below is provided with the cavity of circuit board and element thereof.Its circuit comprises pulse current charge circuit, the full automatic stopping circuit of charging, pickup circuit, pickup treatment circuit, audio amplification circuit.
The cancellation of this charger connects flexible flexible cord, and structure is compact; The charger housing can left and right, following, back four orientation fixing mobile phone.Earphone socket that is provided with and speaker/earpiece change over switch can use more convenient safer, and can not influence other people.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an example structure schematic diagram;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the rearview of Fig. 1.
Fig. 4 is electric functional-block diagram.
Referring to accompanying drawing, be provided with angle of pitch adjusting knob 13 between main body 1 of this charger and the charging plug 12.Be provided with the fixedly groove of mobile phone above main casing, the both sides of groove are provided with snap lock and link closely 2; Be provided with wiring board 5 and the pulse current charge circuit of forming by electronic component thereof, the full automatic stopping circuit of charging, pickup circuit, pickup treatment circuit, audio amplification circuit in the cavity of main casing below, be contained in charging indicator light 6, volume control potentiometer 3, charging output plug 4, signal terminal 14, earphone or earplug socket 15, speaker/earpiece change over switch 16 on the wiring board, with the pick-up 7 and the loudspeaker 8 of lead connection.In the cavity of charging plug 12, be provided with protective tube 10, holddown spring 11 and conduction positive/negative plate 9.
During use, charging plug 12 is directly inserted smoking base socket in the car, make it and the automobile power source conducting, charging indicator light 6 is bright.Then mobile phone is inserted to charger body 1, the output plug 4 of charger and signal terminal 14 engage with the charging input socket and the signal output terminal of mobile phone bottom, and the snap lock of both sides, housing groove top links closely 2 with the mobile phone locking positioning.Headset plug is inserted the earphone socket 15 (when normally using dial to loudspeaker gear put the speaker/earpiece change over switch) of main casing lower rear, be in charging and vehicle-mounted holding state (the vehicle-mounted printed words of mobile phone screen display) this moment.When mobile phone incoming call jingle bell (maybe needing to call, according to number behind the key), can converse with the other side by talk key, avoided taking on the other hand phone, grab the dangerous way of driving of steering wheel on the other hand.When being inconvenient to converse, 16 groups of speaker/earpiece change over switches are put to the earphone gear, use earphone receiving also to stir volume control potentiometer 3 adjustment to suitable volume and answer conversation.
The housing of present embodiment charger body 1 is made of fore shell and bonnet, and its side is half of cucurbit shape.
