Abstract

The utility model relates to a charger, in particular to a portable charger which is used in a secondary battery and comprises a charger shell, an alternating current power input interface which is located on the shell and a charging main board which is located in the shell, wherein the shell is composed of an upper shell and a lower shell which are connected through a rotatable main shaft, wherein the charging main board is located in the lower shell, electrode contacts which are used to connect positive electrodes and negative electrodes of batteries to charge the batteries are respectively arranged on the upper shell and the lower shell, the secondary battery is placed between the upper shell and the lower shell through arranging the electrode contacts in the upper shell and the lower shell, the batteries are fully contacted with air, which is beneficial for dissipating heat of the batteries, and the charging current can be enlarged, the charging time can be reduced, simultaneously, the volume of the charger can be reduced, which is convenient for carrying, a rechargeable solar cell panel is added on the top surface of the upper shell, under the condition of none alternating current power, sun light can be utilized to charge, two groups of electrode contacts are arranged, and batteries with different types can be charged simultaneously.

Description

Portable charger

Technical field

The utility model relates to a kind of charger, especially a kind of portable charger that is used for the secondary battery.

Background technology

Charger is a kind of device of giving the charging of secondary rechargeable battery, traditional charger is made of charger housing, charging circuit board, the charger housing is provided with the battery case of placing battery, when the user uses this charger to charge, battery need be put into battery poor in, when the user need use the battery that is full of electricity, need from battery case, take out rechargable battery one by one, very inconvenient; In addition, the poor many spaces that accounted for whole charger of battery, because other part can not be placed in the poor shared space of battery, the thickness of whole charger just will add the diameter of used battery, this is disadvantageous to the volume that reduces charger, consider that from user's angle this charger does not help carrying and collecting, and traditional charger generally adopts a kind of in alternating current, direct current or the solar recharging.

When the secondary rechargeable battery charges, can produce certain heat, for the secondary rechargeable battery, overheated capacity and the life-span to battery of battery also has negative influence, also may cause danger to the user, traditional charger, battery is placed in the battery case, and the poor all Packed housing in next door and below of battery, these housings can influence the performance of the heat radiation of the new device of charging, therefore the designer is often corresponding for the generation that reduces heat reduces charging current, thereby directly influences the time and the effect of charging.

The utility model content

The utility model technical issues that need to address provide a kind of good heat dissipation effect, volume little, be convenient for carrying, fetching battery is convenient, the portable charger with two kinds of charging modes that contains the solar recharging mode.

For addressing the above problem, technical solution adopted in the utility model is: a kind of portable charger, comprise the charger housing, be positioned at the AC power input interface on the housing, be positioned at the charging mainboard of housing, described housing is made up of upper shell that connects by rotatable shaft and lower house, and the mainboard that wherein charges is positioned at upper shell or lower house, is respectively equipped with on upper shell and lower house and is used for being connected the electrode contacts that battery plus-negative plate charges the battery.

A spring is housed in the described rotary main shaft at least, and described spring is rotated down upper shell along main shaft, contacts until last lower house two-phase opposite.

Described electrode contacts is positioned at enclosure interior up and down, and with porose on the corresponding housing of electrode contacts, electrode contacts passes through lead or directly is connected with the charging mainboard.

This novel further improvement is that the upper shell outer side panel is provided with the solar panels that are used to charge.

The electrode contacts that is positioned on the upper shell is set to 2 groups, and one group is used for battery No. 5, and one group is used for battery No. 7

Adopt the beneficial effect that technique scheme produced to be: this is novel by electrode contacts is set in last lower house, secondary cell is placed between the lower house, battery taking and placing is convenient, and battery fully contacts with air, helps the heat radiation of battery, can increase charging current, reduce the charging interval, simultaneously, reduced the volume of charger, be convenient for carrying, increase the charging solar panels at the upper shell end face, making is not having under the situation of AC power, can utilize the sunlight charging, during charging, sun lights does not get battery on the charging solar panels, help improving battery life, the two arrays of electrodes contact is set, can gives the battery charge of different model simultaneously.

Description of drawings

Fig. 1 is the utility model Facad structure schematic diagram;

Fig. 2 is the utility model reverse side structural representation.

Embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

As Fig. 1, shown in 2, basis is novel to be made up of upper shell 2 and lower house 5, on lower house 5, be provided with AC power input interface 3, charging mainboard 4 is housed in lower house 5 inside, wherein going up lower house connects by rotary main shaft, upper shell 2 can rotate relative to lower house 5, at least one spring is housed in rotary main shaft, spring contacts the opposite face of lower house, during use,, secondary cell is stuck between the lower house as long as with upper shell 2 relative lower house 5 rotating certain angle, battery plus-negative plate respectively be located at lower house in electrode contacts 1 contact, can realize the charging; Electrode contacts 1 lays respectively in the lower house, electrode contacts 1 links to each other with charging mainboard 4 by lead, perhaps directly be connected with charging mainboard 4, position relative with electrode contacts 1 on last lower house is provided with the hole, can position battery very easily, can slippage, charging solar panels 7 also are housed on the outer side panel of upper shell 2, be used under the outdoor nothing electricity situation charging and use.
