Embodiment
As shown in Figure 1, charger assembly 1 of the present utility model comprises electric power connection line 10 and a plurality of charger 20, these a plurality of chargers 20 are a plurality of cradles, and it can join end to end through electric power connection line 10 by the power supply power supply, so that the device to be charged 30 that is connected to each charger 20 is charged.This device 30 to be charged can be the power consumption equipment of rechargeable battery or other built-in rechargeable batteries, in the present embodiment, is example with the rechargeable battery.
Charger 20 as shown in Figure 2, comprises ac input end 21, ac output end 22, AC/DC modular converter 23, charge control module 24 and charging end 25.Wherein, ac input end 21 directly is connected with ac output end 22, and order can be via ac output end 22 outputs by the alternating current of ac input end 21 inputs; 23 of AC/DC modular converters are connected to ac input end 21, so that the alternating current by ac input end 21 inputs is carried out the AC/DC conversion; The direct current that is converted to is delivered to charging end 25 by charge control module 24 controls, and the device to be charged 30 that is connected to this charging end 25 is charged.In the charging process, charge control module 24 is controlled charging current according to the feedback information of device 30 to be charged.
In the present embodiment, charger assembly 1 additionally is provided with electric power connection line 10, and the ac input end 21 of charger 20 is an AC socket, and ac output end 22 is an ac plug.In addition, the ac input end 21 of charger 20 also can be ac plug, and ac output end 22 then is an AC socket, and this ac input end 21 can be connected to an AC power through electric power connection line 10, also can be connected directly to an AC power.
As shown in Figure 3 and Figure 4, can directly the peg graft ac input end 21 of another charger 20 of the ac output end 22 of charger 20 thus, can firmly connect a plurality of chargers 20, and need not to adopt other connectors.In addition, the ac output end 22 of each charger 20 is an ac plug in the present embodiment, is provided with electrocution-proof protection layer 221, is difficult for getting an electric shock with protection personnel when not having other chargers 20 of connection thereafter.And, control switch (figure does not show) can be set on each charger 20, this control switch is connected to charge control module 24, uses for the user and adjusts charging current.This control switch can be provided with a plurality of charging gears, for example fills gear and trickle charge gear etc. soon, and available subscribers is selected as required and adjusted.25 of charging ends can be the charging slot that can place rechargeable battery, as shown in the figure.
During use, electric power connection line 10 is connected to the ac input end 21 of a charger 20, the control of can charging and charge the device to be charged 30 that is connected to this charger 20; If need a plurality of devices 30 to be charged are charged simultaneously, then the ac output end 22 of this charger 20 is plugged to the ac input end 21 of another charger 20,22 of the ac output ends of this another charger 20 are plugged to the ac input end 21 of the 3rd charger 20, ..., so a plurality of chargers 20 head and the tail are successively connected, constitute charger assembly 1, can be simultaneously to the control of charging and charge respectively of a plurality of devices 30 to be charged, as shown in Figure 1.Because a plurality of chargers 20 in this charger assembly 1 can adopt identical structure and specification to make, therefore, the front and back of its grafting order can be adjusted arbitrarily as required.
After the connection, the circuit structure block diagram of charger assembly 1 as shown in Figure 5, the ac input end 21 of a plurality of chargers 20 is connected with ac output end 22, and be connected to AC power (100~240VAC), therefore all can obtain alternating current, AC-DC conversion work is then finished separately by each charger 20, with control that the device to be charged 30 that connects is separately charged and charges, this shows, though a plurality of chargers 20 of the utility model charger assembly 1 externally form the structure that is connected in series on the structure, but on electrical structure, particularly for the device to be charged 30 that each charger 20 connects, then form the structure that is connected in parallel, respectively each device 30 to be charged is charged.Therefore, adopt the independent current source adaptation unit to carry out carrying out the branch current charge again after AC/DC is changed with prior art and compare, the utility model charger assembly 1 can have bigger charging current, the charge efficiency height to each device 30 to be charged; And the quantity of the quantity of its attachable charger 20 that is device to be charged 20 is then determined by the load capacity of electric power connection line 10, ac input end 21 (AC socket), ac output end 22 (ac plug).In addition, when a certain device 30 to be charged breaks down, can not influence the charging process of other devices 30 to be charged.
This shows, the utility model charger and charger assembly only need a supply socket to charge for a plurality of devices to be charged simultaneously for a plurality of chargers, save resource and space, reduce use cost, and a plurality of chargers only need to peg graft each other and can use, safe ready further strengthens its safety in utilization thereby also can add the electrocution-proof protection facility simultaneously at the ac output end of each charger; Secondly, the equal incoming transport of the ac input end of a plurality of chargers of the present utility model, and the AC/DC conversion work is carried out with control that the device to be charged that connects is separately charged and charges separately by each charger, therefore each charger can provide bigger charging current, charge efficiency is greatly enhanced, particularly, when a device to be charged broke down, the charging process of other devices to be charged can not be affected; As for the quantity of the attachable charger of charger assembly, then can determine by the load capacity of electric power connection line, charger ac input end and ac output end.In addition, charger of the present utility model can adopt same structure and specification, not only is convenient to random grafting, also is beneficial to batch process, to reduce production costs.
The above only is preferred embodiment of the present utility model; be not in order to limit practical range of the present utility model; therefore all other do not break away from the equivalence of being finished under the spirit that the utility model discloses and changes or modify, and all should be included in the protection range of the present utility model.
