[0003] The existing shared power banks are short-term rental power bank services operated by enterprises. Through adding shared power banks to a charging device for fast charging processing, users insert the used shared power banks into a dedicated fast charging device for efficient power replenishment. During the docking of the power bank and the fast charging socket, the connecting piece will be subjected to the thrust of the power bank insertion action, which will then cause the spring to be compressed, enabling the internal contact joint to accurately embed into the contact slot, thereby realizing the effective contact between the charging head and the power bank and the charging process. However, during the actual charging process, due to the continuous elastic force of the spring and the inevitable wear of the charging head after long-term use, it may cause accidental detachment or poor contact problems during the charging process of the charging device.

Specific embodiments

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] In the specific implementation process, as Figures 1 to 5 shown, the fast charging device for shared power banks includes a box body 1, on which a plurality of charging slots 2 are equidistantly opened. Inside the box body 1, a storage battery and a circuit board connected by wires are provided. The circuit board is fixedly connected to a contact port 3 on the inner bottom wall of the charging slot 2 through a wire. A partition plate 7 is fixedly connected above the contact port 3 in the charging slot 2. Fixed components are movably penetrated through both sides of the partition plate 7. The outer side wall of the fixed component is slidably connected to a connecting plate 4, and a first elastic member 5 is provided directly between the fixed component and the connecting plate 4. The bottom of the connecting plate 4 is fixedly connected to a contact joint 6. A movable block 8 is slidably connected to the top of the contact port 3 on the partition plate 7. A charging head 9 is fixedly connected to the movable block 8. The charging head 9 is connected to the contact joint 6 through a wire. A second elastic member 10 is fixedly connected between the bottom of the movable block 8 and the bottom of the charging slot 2;

[0022] The fixed component includes a first cylinder 11 and a first cylinder 18 arranged coaxially. The outer side wall of the first cylinder 11 is slidably connected to the partition plate 7. The bottom of the first cylinder 18 is connected to the charging slot 2, and the first cylinder 11 is located outside the first cylinder 18. The adjacent ends of the first cylinder 11 are fixedly connected to a fixing plate 12. Both ends of the first elastic member 5 are fixedly connected to the fixing plate 12 and the connecting plate 4 respectively. One end of the first cylinder 11 is fixedly connected to a second cylinder 13. The second cylinder 13 can be attached to the bottom of the partition plate 7. A telescopic bracket 14 is slidably connected to the side wall of the second cylinder 13. An annular disc 15 is fixedly connected to the outside of the second cylinder 13 of the telescopic bracket 14. A sliding head 16 with a trapezoidal cross-section is fixedly connected to the inside of the second cylinder 13 of the telescopic bracket 14. A third elastic member 17 is provided on the outer side wall of the telescopic bracket 14, and both ends of the third elastic member 17 are fixedly connected to the sliding head 16 and the inner side wall of the second cylinder 13 respectively;

[0023] At the top of the first cylinder 18, a limiting rod 19 and a limiting bracket 20 are fixedly connected in sequence. The cross-section of the limiting bracket 20 is semi-circular, and an annular groove is provided at the inner top of the limiting bracket 20. A sliding bracket 21 is arranged on the outer surface of the limiting rod 19. The sliding bracket 21 can slide along the outer wall of the limiting rod 19, and the upper end of the sliding bracket 21 can be embedded in the annular groove provided in the limiting bracket 20;

[0024] The first elastic member 5, the first elastic member 5, and the third elastic member 17 are all springs. The spring can accumulate elastic potential energy when subjected to pressure and release the elastic potential energy when the pressure is cancelled, so as to achieve the reset effect.

[0025] The working principle provided by the present utility model is as follows: When the present utility model is specifically implemented, the power bank is placed along the charging slot 2 of the box body 1, and through movement, it is docked with the charging head 9. The charging head 9 is arranged on the movable block 8, and the elastic member two 10 at the bottom of the movable block 8 provides a bearing capacity for the movable block 8 due to its elastic potential energy. During the docking process, the charging head 9 contacts the first cylinders 11 on both sides, causing the first cylinders 11 to move downward. At this time, due to the influence of gravity, the sliding bracket 21 on the outer sidewall of the limiting rod 19 will be located at the top of the first cylinder 18. During the falling process, the sliding head 16 on the second cylinder 13 will contact the limiting bracket 20, and as the semi-circular shape gradually becomes larger, the sliding head 16 will contract into the second cylinder 13 and squeeze the elastic member three 17. When the sliding head 16 falls and disengages from the contact with the limiting bracket 20, it will be placed between the bottom of the limiting bracket 20 and the sliding bracket 21, thereby fixing the first cylinder 11. At this time, the power bank is in a state of being docked with the charging head 9. After the first cylinder 11 descends, it drives the connecting plate 4 at the bottom to move downward through the elastic member one 5. At this time, the connecting plate 4 contacts the electric contact port 3, causing the elastic member one 5 to be in an initial extrusion state. The downward movement of the connecting plate 4 drives the electric contact joint 6 to move towards the electric contact port 3 and dock. Thus, through the docking of the electric contact port 3 and the electric contact joint 6, and the wire connection between the electric contact joint 6 and the charging head 9, the power bank on the charging head 9 is charged. After the power bank is fully charged, by applying a driving force to the power bank, it drives the charging head 9 and the first cylinder 11 at the bottom to move downward. The elastic member two 10 at the bottom of the charging head 9 generates elastic potential energy under pressure. At the same time, the downward pressure of the first cylinder 11 drives the elastic member to continuously press downward, thereby generating sufficient elastic potential energy. At this time, the sliding head 16 in the first cylinder 11 first contacts the top of the sliding bracket 21 and contracts again as its outer dimension decreases. When the sliding head 16 is at the lower end of the sliding bracket 21, due to its gradually decreasing size, the elastic potential energy of the elastic member three 17 drives the sliding head 16 to move upward, so that it contracts into the sliding groove of the limiting bracket 20. At this time, the applied force on the power bank is cancelled, and through the elastic potential energy of the elastic member one 5 and the elastic member two 10, the sliding head 16 is driven to move upward and sequentially disengage from the sliding bracket 21 and the limiting bracket 20, thereby driving the first cylinder 11 and the charging head 9 to move upward, causing the power bank to protrude from the charging slot 2, so that it can be taken out.

[0026] The circuits and controls involved in the present utility model are all prior arts and will not be elaborated herein.

[0027] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
