Embodiment 1

[0048] see Figure 1 to Figure 4 , a mobile power supply, including an input interface 103, an output interface 104, a circuit board 102, a wire 106, a waterproof layer 108, an isolation layer 110, an electric core 105 and a casing 101.

[0049] The shell 101 is provided with two openings, and the two openings are respectively used to expose the access interface and the output interface 104, so as to facilitate the connection of the external power transmission line and the connector;

[0050] The input interface 103 is a Micro-USB socket, and the output interface 104 is a USB socket; both the input interface 103 and the output interface 104 are fixed with the circuit board 102 by welding, and the end of the input interface 103 and the output interface 104 away from the circuit board 102 is arranged in the opening. The outer wall of the input interface 103 and the output interface 104 is provided with a waterproof layer 108, the waterproof layer 108 is made of elastic material,...

Embodiment 2

[0070] see Figure 5 , Embodiment 2 of the present invention provides a mobile power supply. The difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, a shock-absorbing layer 112 is provided on the outside of the battery cell 105, and the two ends of the shock-absorbing layer 112 are respectively against the The isolation layer 110 and the casing 101 outside the cell 105 .

[0071] The shock-absorbing layer 112 is used to connect the battery core 105 and the shell 101 to prevent the battery core 105 from shaking when the mobile power supply is working, or to be impacted when the mobile power supply is bumped, so as to improve the working environment of the battery core 105 and prolong the battery life. The service life of the core 105.

[0072] In this embodiment, the material of the shock absorbing layer 112 is rubber. In addition, TPE, PVC, NBR, foam and other materials can also be selected.

Abstract

The invention provides a mobile power supply, which belongs to the field of electronic accessories. The mobile power supply comprises an input interface, an output interface, a circuit board, a wire, an electric core and a shell, wherein the shell is provided with two openings, and the two openings are respectively corresponding to the input interface and the output interface; the outer side wall of the input interface and the output interface is provided with an anti-water layer made of an elastic material; the anti-water layer is used for filling gaps between the input interface and the output interface and the openings, and areas where the anti-water layer and the openings are contacted are in a compression state. The anti-water layer made of the elastic material is arranged on the outer side wall of the input interface and the output interface, the areas where the anti-water layer and the openings are contacted are in a compression state, the gaps between the openings and the two interfaces are filled, and anti-water performance of the mobile power supply is improved; and in addition, through filling the gaps, the interfaces have less shaking during a plug-pull process.

Description

technical field [0001] The present invention relates to the field of electronic accessories, in particular, to a mobile power supply. Background technique [0002] Power bank, commonly known as power bank, is a portable charger that integrates power supply and charging functions, and can charge mobile phones, tablet computers and other digital devices anytime, anywhere. Generally, lithium batteries (or dry batteries) are used as power storage units, which are easy to use. [0003] As the size of mobile phones shrinks day by day and the power consumption of mobile phone screens is getting faster and faster, the battery life of current smart phones is greatly reduced. The problem of insufficient power used by smart terminals has catalyzed the rapid development of mobile power. As an easy-to-carry charging power source, mobile power has a high popularity rate now. [0004] The inventor found in research that the mobile power supply in the prior art lacks waterproof function....
