Description

Technical Field

[0001] The utility model relates to a mobile power supply, in particular to a mobile power supply device which can conveniently adjust the position of a connector and solve the problem of elastic fatigue of a spring. Background Art

[0002] With the improvement of people's living standards and the progress of the times, modern urban residents generally use some mobile communication devices (such as mobile phones, smart phones and tablet computers). Therefore, mobile communication devices have even become a necessity in modern life. In order to keep their mobile communication devices powered, many people carry mobile power banks with them.

[0003] Existing power banks mainly require a transmission cable to charge mobile communication devices. The power bank is equipped with connectors for input and output power, and the transmission cable connects the power bank and the mobile communication device to supply power to the mobile communication device. However, the existing power bank and transmission cable are separately provided, which makes it easy to forget to bring the transmission cable or temporarily misplace the transmission cable. In addition, when the transmission cable and power bank are carried together, it is easy for the transmission cable to become tangled, stuck, or even break.

[0004] Therefore, some manufacturers have launched products that incorporate the connector into the power bank. The folding of the connector is adjusted by using a metal spring. However, the use of the metal spring is prone to elastic fatigue, which may cause the folding to become fixed.

[0005] Therefore, how to solve the above problems and deficiencies of the prior art is an urgent research and improvement direction that the inventors of the present invention and related manufacturers engaged in this industry need to focus on. Utility Model Content

At the same time, a connector 31 is provided on the inner assembly 3, and an electrical connector 311 protrudes from the outer side of the connector 31. The electrical connector 311 can be TYPE-C or Micro A power transmission connector such as USB or Lightning, and the connector 31 and the electrical connector 311 are accommodated in the upper shell accommodating groove 21. In this embodiment, the connector 31 and the electrical connector 311 are accommodated in the upper shell accommodating groove 21 in parallel, and a side group portion 32 is formed on both sides of the connector 31. The side group portion 32 passes through the two side walls of the upper shell accommodating groove 21 and extends into the interior of the upper shell 2. At the same time, a first connector 33 is provided on the other side of the side group portion 32 relative to the connector 31. The first connector 33 has a plurality of first ribs 331 and a plurality of first card slots 332 arranged in sequence. At the same time, the first connector 33 has a plurality of first ribs 331 and a plurality of first card slots 332 arranged in sequence. A second connecting member 34 is provided on the other side of the connecting member 33 opposite the side assembly portion 32. The second connecting member 34 has a plurality of second ribs 341 and a plurality of second slots 342 arranged in sequence. The first rib 331 is engaged with the second slot 342, and the second rib 341 is engaged with the first slot 332. In addition, an elastic member 35 is provided on the second connecting member 34, and the side assembly portion 32, the first connecting member 33, the second connecting member 34, and the elastic member 35 are accommodated in the upper shell embedded groove 22, and one end of the elastic member 35 contacts the second connecting member 34, and the other end contacts the inner top wall 23 of the upper shell 2.

[0042] Please refer to the above drawings and Figure 5 The figure shows a partial implementation diagram of the mobile power supply device of the present invention. Figure 1When the power bank device 1 is used, the connector 31 and the electrical connector 311 can be directly lifted from the upper housing accommodating groove 21, so that the connector 31 is lifted with the side groups 32 on both sides as the axis. When the connector 31 is lifted, the connector 31 is obliquely arranged in the upper housing accommodating groove 21, and the connector 31 drives the side groups 32 to rotate. When the side groups 32 rotate, the side groups 32 simultaneously drive the first connector 33 to rotate. When the first connection rotates, the first rib 331 and the second rib 341 will respectively disengage from the second slot 342 and the first slot 332, and the first rib 331 will contact the second rib 341 and push the second rib 341. When the second rib 341 is pushed, it will drive the second connector 34 to move toward the inner top wall 23, and the second connector 34 will squeeze the elastic member 35.

[0043] Please refer to the above drawings and Figure 6 and Figure 7 The figure shows a partial implementation diagram of the mobile power supply device of the present invention. Figure 2 And implementation diagram, then continue to pull the connector 31 and the electrical connector 311, so that the connector 31 is continuously pulled with the side group parts 32 on both sides as the axis, and the connector 31 is pulled to be vertically arranged in the upper shell accommodating groove 21, and the connector 31 also drives the side group part 32 to rotate, and when the side group part 32 continues to rotate, the side group part 32 will simultaneously continue to drive the first connector 33 to rotate, and when the first connection continues to rotate, the first rib 33 1 and the second rib 341 will move toward the second slot 342 and the first slot 332 respectively until the first rib 331 is locked in the second slot 342 and the second rib 341 is locked in the first slot 332. The elastic member 35 releases its elastic force and the first rib 331 is locked in the second slot 342 and the second rib 341 is locked in the first slot 332, thereby fixing the connector 31 protruding from the upper housing receiving slot 21.
