Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0033] As mentioned in the background technology section, the existing mobile power supply only has the function of charging. In practical applications, in order to realize the multimedia signal on the mobile terminal can be played on an external display device, a new multimedia interface MHL customized for mobile terminals is becoming popular and has become the standard configuration of most high-end mobile phones and tablet computers. . However, since the input signal of external display devices such as TVs and monitors is generally HDMI, it is not compatible with MHL, so an MHL-to-HDMI adapter acts ...

Abstract

The invention provides a mobile power supply and a charging system. The mobile power supply includes a Micro-USB interface socket, an HDMI interface socket and a USB interface socket supporting MHL signal connection. The Micro-USB interface is used to charge the mobile power supply, the HDMI interface socket is used to connect the HDMI plug of the external display device, and the USB interface socket supporting MHL signal connection is used to connect the MHL interface of the mobile terminal. After the USB interface socket supporting MHL signal connection on the mobile power supply is connected to the MHL interface on the mobile terminal, the mobile power supply can charge the mobile terminal, and the MHL signal on the mobile terminal can be transmitted to the mobile power supply simultaneously. Since the mobile power supply is also provided with an HDMI interface socket, the MHL signal transmitted from the mobile terminal to the mobile power supply can be transmitted to the external display device through the HDMI interface on the mobile power supply, so that the multimedia signal on the mobile terminal can be displayed outside. Play on the display device.

Description

technical field [0001] The invention relates to the field of power storage devices, in particular to a mobile power supply and a charging system. Background technique [0002] With the rapid development of electronic technology, the functions of mobile terminals such as smartphones, iPads and tablets are increasing, and their power consumption is also rising. The standby time of the mobile terminal is relatively short, even less than one day. In this case, the mobile power supply that is convenient to carry and can charge the mobile terminal at any time, so that the user can escape from the predicament of affecting normal work due to the exhaustion of the mobile terminal's power is Batteries with strong storage capacity are gradually favored by mobile terminal users. [0003] figure 1 A schematic structural diagram of a conventional mobile power supply in the prior art is shown. A conventional mobile power supply in the prior art is provided with a Micro-USB (micro-USB) i...
