[0026] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0027] The utility model discloses a tail plug mobile power supply, combined with Figures 1 to 8 As shown, it includes a shell 1, and an upper shell component 4 is fixed on the top of the shell 1. The upper shell component 4 includes a receiving groove 40 and an elastic support arm 41 arranged at the bottom of the receiving groove 40. A flip plug 5 is rotatably connected in the receiving groove 40. The flip plug 5 is provided with a first clamping portion 50, a second clamping portion 51 and an electrical plug terminal 52. When the electrical plug terminal 52 is flipped to the outside of the receiving groove 40, the first clamping portion 50 is clamped and connected with the elastic support arm 41. When the electrical plug terminal 52 is flipped to the inside of the receiving groove 40, the second clamping portion 51 is clamped and connected with the elastic support arm 41.

[0028] In the above structure, an upper shell component 4 is arranged on the top of the shell 1, and the function of the upper shell component 4 is to accommodate the flip plug 5 and enable the flip plug 5 to flip. At the same time, an elastic arm 41 is arranged at the bottom of the accommodating groove 40 in the upper shell component 4, and the elastic arm 41 is used to apply elastic stress to the flip plug 5. The elastic stress can not only apply a certain damping to the flip plug 5 to prevent the flip plug 5 from moving, but also can be elastically matched with the first clamping portion 50 and the second clamping portion 51. When the user needs to charge, the electric plug end 52 is flipped out of the accommodating groove 40. At this time, the first clamping portion 50 is engaged with the elastic arm 41, thereby limiting the flip plug 5 to a state of flipping outward. When charging is completed, the electric plug end 52 is flipped into the accommodating groove 40. At this time, the second clamping portion 51 is engaged with the elastic arm 41, thereby limiting the flip plug 5 to a state of being hidden in the accommodating groove 40. Based on the above principle, it can be seen that the utility model can not only extend and hide the electrical plug terminal, but also does not require complex hinges and limiters, thereby simplifying the number of components, which not only reduces product costs but also facilitates manufacturing and assembly.

[0029] To realize the basic functions of a mobile power source, in this embodiment, a battery 2 and a PCB board 3 are disposed in the housing 1 , and the electrical plug terminal 52 and the battery 2 are both electrically connected to the PCB board 3 .

[0030] Combination Figures 3 to 5 As shown, in this embodiment, the upper shell assembly 4 includes an inner shell 42 and an upper shell 43 fixedly connected to each other, the receiving groove 40 is formed on the inner shell 42, and the upper shell 43 is provided with a receiving opening 430 corresponding to the receiving groove 40.

[0031] Specifically, two receiving grooves 40 are provided on the inner shell 42 , and the flip plugs 5 are both provided in the two receiving grooves 40 . The electrical plug ends 52 of the two flip plugs 5 have different interface types.

[0032] In this embodiment, the combined structure of the inner shell 42 and the upper shell 43 is used to accommodate and restrict the two flip plugs 5. In actual applications, the electrical plug ends 52 of the two flip plugs 5 have different interface types. For example, the electrical plug end 52 of one of the flip plugs 5 is a type-c plug end, which can be used as an output end for outputting electric energy to the outside and as an input end for charging the battery 2. Therefore, after the type-c plug end is adopted in this embodiment, there is no need to set up another power input interface; the other flip plug 5 can be a Lightning interface or a micro-usb interface.

[0033] In order to ensure that the elastic arm 41 has sufficient elasticity and meets the requirements of providing damping and elastic engagement, in this embodiment, the elastic arm 41 is in an arc shape. Furthermore, the bottom of the receiving groove 40 is semicircular, and the elastic arm 41 extends along the bottom of the receiving groove 40. Specifically, a narrow groove 400 is formed between the elastic arm 41 and the bottom of the receiving groove 40, and the narrow groove 400 not only enables the elastic arm 41 to have sufficient elasticity, but also enables the elastic arm 41 to transition along the arc shape of the bottom of the receiving groove 40. In actual application, the receiving groove 40, the elastic arm 41 and the inner shell 42 are integrally injection molded, which is not only easy to manufacture, but also does not require other components to apply damping and limit the flip plug 5.

[0034] In order to achieve reliable card connection, Figures 3 to 5 As shown, the first clamping portion 50 and the second clamping portion 51 are both convex blocks, and the end of the elastic arm 41 is formed with a clamping portion 410 for clamping and connecting with the first clamping portion 50 and the second clamping portion 51. In actual application, when the electrical plug end 52 is flipped into the receiving groove 40, the first clamping portion 50 is exposed, and when the electrical plug end 52 is flipped out of the receiving groove 40, the second clamping portion 51 is exposed. Based on the exposed first clamping portion 50 or second clamping portion 51, the flip plug 5 can be easily controlled to flip.

[0035] Combination Figure 6 and Figure 7 As shown, as a preferred embodiment, the two flip plugs 5 are coaxially arranged, and the two flip plugs 5 are rotatably connected via an inner shaft 53 and a sleeve 54. Further, an outer shaft 55 is provided on the outer side of the two flip plugs 5, and the sleeve 54 and the two outer shafts 55 are rotatably connected to the upper shell 43.

[0036] In the above structure, see Figures 6 to 8 The two flip plugs 5 are coaxially and arranged side by side, which not only facilitates the rotation and connection of the two to the upper shell 43, but also has another important function of foolproofing, that is, in actual application, only when the electrical plug end 52 of one flip plug 5 is flipped outward, it can be plugged into the mobile terminal. When the electrical plug ends 52 of the two flip plugs 5 are flipped outward, the position of the electrical plug ends 52 will interfere, resulting in the mobile power supply being unable to be plugged into the terminal device, thereby ensuring safety and reliability during use.

[0037] This embodiment also has a wireless charging function, see Figure 2The front side of the housing 1 is provided with a wireless charging module 6 and a front cover 7, the front cover 7 is provided on the front side of the wireless charging module 6, and the front cover 7 is fixedly connected to the housing 1, and the wireless charging module 6 is electrically connected to the PCB board 3. The wireless charging module 6 can be a watch charging module or a mobile phone charging module.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
