Abstract
The utility model provides a kind of power supply device of dual power supply, the power supply device includes power pack, buckle and battery, the power pack includes at least one DC input and DC output end, the buckle is fixedly connected on power pack, and the battery is electrically connected by the buckle with the power pack.Above-mentioned apparatus solves the disadvantage that existing external power supply unit cannot be guaranteed continued power, can in the state of not powering off auto switching electric source, with while replacing battery guarantee work do not interrupt.
Description
Technical field
The utility model relates to a kind of external power supply unit more particularly to a kind of power supply devices of dual power supply.
Background technique
External power supply unit currently on the market is powered using single power supply mostly, when need replacing battery or
When mobile power supply unit, it has to first stop power supply, power again again after battery altering or equipment are mobile.In such case
Under, the continuity of equipment work cannot be guaranteed, and bring inconvenience to some equipment for needing continuous work.The utility model mentions
For a kind of power supply device of dual power supply, guarantee that power supply device replaces battery during power supply to the device, equipment is not yet
It can power off, that is, work and do not have to interrupt.Dual power supply warm back-up is also provided simultaneously, so that equipment power supply is more safe and reliable.
Summary of the invention
The purpose of this utility model is to provide a kind of power supply devices of dual power supply, are not being powered off by power supply device
In the state of auto switching electric source, guaranteeing to work while replacing battery will not interrupt.Dual power supply warm back-up is also provided simultaneously,
So that equipment power supply is more safe and reliable.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of power supply device of dual power supply,
The power supply device includes power pack, buckle and battery, and the power pack includes at least one DC input and direct current
Output end, the buckle are fixedly connected on power pack, and the battery is electrically connected by the buckle with the power pack.
In above-mentioned power supply device, the DC input connects other power supplys by direct Current Outlet.
In above-mentioned power supply device, the connecting pin of the battery passes through the metal clips and buckle electricity on the buckle
Connection.
In above-mentioned power supply device, the buckle is electrically connected by electric wire with the power pack.
In above-mentioned power supply device, the buckle is fixed by screws on the power pack.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical solution of the utility model embodiment
The attached drawing used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the utility model
Example, for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other alternate embodiments.
Fig. 1 is the power device structure schematic diagram of dual power supply provided by the utility model, including power pack (1), button
Plate (2), battery (3), DC input (4) and DC output end (5).
Fig. 2 is the power supply device schematic view of the mounting position of dual power supply provided by the utility model, power pack (1) and straight
Galvanic electricity input terminal (4) connection, buckle (2) are fixed on power pack (1), and battery (3) is mounted in buckle (2).
Specific embodiment
Below with reference to embodiment, the utility model is described in further detail, but these embodiments are not constituted to the utility model
Protection scope limitation.
This example provides a kind of power supply device of dual power supply, including power pack, buckle and battery, power pack include
One DC input and DC output end, buckle are fixed by screws on power pack, and battery is buckled by described
Plate is electrically connected with the power pack.Wherein, the DC input connects other power supplys by DC5521 direct Current Outlet,
Input maximum current is 5A, and voltage is 9~28V.It exports electric current and voltage is substantially consistent with input current and voltage.Wherein, electric
The connecting pin in pond is electrically connected by the metal clips on buckle with buckle, and buckle is electrically connected by electric wire with power pack.
By circuit control, the dual power supply of above-mentioned apparatus is realized.As shown in Figure 1, if having battery (3) and direct current simultaneously
Electrical input (4) access, power supply device will preferentially use DC input (4) as power supply power supply.
If the power supply of DC input (4), without electricity or when being unplugged, power supply device will automatically switch to battery (3)
It is powered.
If currently powering for battery (3), after DC input (4) is powered, power supply device will automatically switch to direct current
Input terminal (4) is powered.
If currently powering for DC input (4), plugging battery (3) does not influence means of power.
Above-mentioned power supply device can guarantee power supply device during power supply to the device, automatic in the state of not powering off
Switching power to guarantee that work is not interrupted while replacing battery, while also providing dual power supply warm back-up, and power supply to the device is more
Securely and reliably.The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
Subject to the scope of protection of the claims.
