Description

Multifunctional mobile phone charger

Technical field

The utility model relates to a kind of charger for mobile phone, two kinds of multifunctional mobile phone chargers that charging modes is an one of particularly a kind of collection.

Background technology

The common function singleness of the charger for mobile phone of Xiao Shouing in the market, for example can be to the seat formula charger of charging mobile phone battery, to the traveling charger of the direct charging of mobile phone and the vehicle charger that on automobile, uses etc., so multiple charging modes makes a mobile phone must be equipped with a plurality of chargers satisfying the use needs under the different situations, to the carrying of people, deposit, use etc. has brought inconvenience; In order to overcome above-mentioned shortcoming, people have carried out multiple improvement, occurred a kind ofly seat is filled and travelling and filling the charger that is integrated in one, but itself and external power supply ways of connecting have only a kind of, promptly be only limited on the AC power that indoor socket is used and use, can give mobile phone or charging mobile phone battery simultaneously; On the other hand, commercially available charger for mobile phone has long coiling usually and exposes usually, is easy to like this twine and knotting, and sometimes even can cause electric wire to fracture and cause short circuit, and long lead twines and folding and unfolding gets up to be not easy to use and carry.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of interchange input plug that indoor socket is used that both had, what have automobile-used direct current input plug again can realize the multifunctional mobile phone charger that car fills and travels and fill, and retracting device can be taken in lead in the charger housing automatically.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of multifunctional mobile phone charger, comprise charging circuit board in the housing, housing and the input plug that is connected with external power supply, the output plug that is connected with mobile phone, described input plug comprises the input plug that exchanges that automobile-used direct current input plug and indoor socket use; The lead of above-mentioned output plug end can be taken in the housing under the drive of retracting device; Described retracting device is automatic retracting device, it is in the upper shell and the cavity between the lower house of housing, comprise a rotating shaft of stretching out from lower housing cavity, " worker " molded lines wheel that twines for lead that can rotate around the axis and place the supporting plate of wind spring and be installed on switch on the upper shell, be provided with ratchet in the endoporus of the enwinding spring axis on " worker " molded lines wheel top, can stretch into part in the endoporus with switch and block mutually and throw off, an end of wind spring is fixed on the bayonet socket of enwinding spring axis; The housing of described automotive coupler end is with lid outward; The end of described output plug can snap in the hook on the housing.

The beneficial effects of the utility model are: car is filled and trip fills with input plug and concentrates on the charger, the user only need be equipped with the charging that a charger just can satisfy tributary power supply in the charging of indoor AC power and the automobile; Owing to adopted automatic retracting device, can lead income charger housing with the output plug end in, avoided the problem that lead twines and knotting brings, made things convenient for people use, carry and deposit; The electrode contact blade of automobile-used input plug end is softer, is with lid outside it, can prevent collision and damage plug.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a perspective exploded view of the present utility model;

Fig. 2 is the switch of the utility model retracting device and the schematic perspective view that " worker " molded lines wheel cooperates;

Fig. 3 is the utility model user mode schematic diagram.

Embodiment

With reference to Fig. 1, multifunctional mobile phone charger of the present utility model, comprise charging circuit board 3 in the housing 1, housing 1 and the input plug 4 that is connected with external power supply, the output plug 5 that is connected with mobile phone, described input plug 4 comprises that automobile-used direct current input plug 42 and indoor socket use exchanges input plug 41.Input plug 4 ends and output plug 5 ends are by certain circuit communication, and its interconnected relationship and electric elements are conspicuous for those of ordinary skills, do not do detailed description at this.

The lead 51 of output plug 5 ends in the present embodiment can be taken under the drive of retracting device 6 in the housing 1, can avoid lead to twine like this and problem that knotting brings, and is easy for people to use, carry and deposit.Be to have adopted automatic retracting device in the present embodiment, this device is in the upper shell 12 and the cavity between the lower house 11 of housing 1, stretch out a rotating shaft 61 and pass circuit board 3 from lower house 11 inner chambers, this rotating shaft 61 can with lower house 11 integrated injection moldings, be with the supporting plate 62 of placement wind spring 65 and " worker " molded lines wheel 64 of 61 rotations around the shaft in the rotating shaft 61, " worker " molded lines wheel 64 can twine on it switch 63 that also is equipped with on upper shell 12 for lead 51.

With reference to Fig. 2, there is enwinding spring axis 641 on the top of " worker " molded lines wheel 64, and an end of wind spring 65 is fixed on the bayonet socket 643 of enwinding spring axis 641, is provided with ratchet 642 in the endoporus of enwinding spring axis 641, can block mutually with the part 631 that switch 63 stretches into endoporus and throw off.

With reference to Fig. 3, the utility model is pulled out output plug 52 and is inserted mobile phone in use, at this moment, 64 rotations of " worker " molded lines wheel drive wind springs 65 and are wrapped on the enwinding spring axis 641, pull out Len req after, pull switch 63, the part 631 that makes switch 63 stretch into endoporus is blocked the ratchet 642 in the enwinding spring axis endoporus, then lead 51 can not bounce back, to be charged finishing, pull switch again, make it and ratchet breaks away from, then wind spring 65 retractions drive that leads 51 are wrapped on " worker " molded lines wheel 64 and in the income housing 1.

Certainly, the form that furls that the automatic retracting device of this lead can be in the present embodiment to be adopted or other similarly furl form, also can adopt manual retracting device, as furling of realizing by mechanical structures such as rotating shaft, hand-operated rocker arms, the technical scheme that it adopted, the function of realization and the technique effect that reaches should be considered as being equal to.

Because the electrode contact blade of automobile-used input plug end is softer, can be in its overcoat upper cover body 7, to prevent collision and to damage plug.

For the fixing end 52 of output plug 5, hook 2 can be set on housing 1, plug ends is stuck in the groove, also can be in other position of housing, as surface etc. groove is set directly and holds plug ends, the technical scheme that it adopted, the function of realization and the technique effect that reaches also should be considered as being equal to.
