Utility model content

The utility model proposes that a kind of structure is simple, small in size, capacity is big, interface mainly for the deficiencies in the prior art More Portable AC-DC dual-purpose power supply devices.

The utility model is achieved through the following technical solutions technical goal.

Portable AC-DC dual-purpose power supply device, it includes shell, handle, shield, panel, inverter, lithium battery and branch Frame.The shell is prone position caged, and built-in bracket is for being fixedly mounted lithium battery and inverter.It is theed improvement is that: institute It states handle and is placed in case top middle position, the panel that shell both ends are set up separately is locked with shield, pacified in frontal panel System switching, direct current disengaging end interface, display screen, USB interface and fuse are filled, two are mounted side by side on the panel at the back side Exchange accessory power outlet.

As the scheme of further improvement, the shield is excellent power glue product.

As the scheme of further improvement, the voltage value of the direct current disengaging end interface is 24V.

As the scheme of further improvement, the voltage value of the USB interface is 5V.

As the scheme of further improvement, edge is evenly distributed with ventilation hole on the panel.

As the scheme of further improvement, the lithium battery is ternary lithium battery.

As the scheme of further improvement, the inverter is that 24V direct current turns 220V AC inverter.

The utility model compared with prior art, has the positive effect that:

1, compact-sized, rationally distributed, light-weight, it is easy to carry；

2, multiple functional, interface is more, meet conventional electronic device for electricity demanding；

3, installed capacity is relatively large, and charging time is long.

Specific embodiment

Below according to attached drawing and in conjunction with the embodiments, the utility model is described in further detail.

Fig. 1 and Portable AC-DC dual-purpose power supply device shown in Fig. 2, it include shell 1, handle 2, shield 3, panel 4, Inverter 5, lithium battery 6 and bracket 7.The shell 1 is prone position caged, built-in bracket 7 as shown in Figure 7, lower layer's fixed installation Inverter 5 is fixedly mounted in ternary lithium battery 6, upper layer.The handle 2 is placed in 1 top middle position of shell, 1 both ends of shell point If panel 4 locked with shield 3 as shown in FIG. 6.Shield 3 in the present embodiment makes of excellent power glue, and excellent power glue is also known as poly- Urethane PU elastomer, the component of the material in addition to the function of connecting panel 4 for shell 1, also have vibration reduction and cushioning in the structure Function can avoid collision bring damage in carrying process.As shown in figures 1 and 3 positioned at frontal panel 4, installation is respectively System switch 4.1, direct current disengaging end interface 4.2, display screen 4.3, USB interface 4.4 and fuse 4.5.Positioned at the back side panel 4 such as Shown in Fig. 4, two exchange accessory power outlets 4.6 are mounted side by side.In the present embodiment, matched lithium battery is the large capacity of 24V50Ah Ternary lithium battery, the voltage value that direct current passes in and out end interface 4.2 is 24V, and the voltage value of USB interface 4.4 is 5V, and inverter 5 is 24V Direct current turns 220V AC inverter.It dissipates for the ease of built-in lithium battery 6 and inverter 5, uniformly divulges information in the upper edge of panel 4 Hole 4.7, the ventilation hole 4.7 on the panel 4 at both ends constitute the air duct for running through 1 inner cavity of shell, have good cooling effect.
