[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a waterproof and dustproof multifunctional power bank, including a power bank body 1 and a sealing shell. The sealing shell is fitted onto the end of the power bank body 1 where the charging port is located. A frame 2 is fitted onto the power bank body 1 near the sealing shell. The sealing shell is divided into two halves 3 in the middle. The halves 3 are fixedly connected to the frame 2 by a torsion spring hinge. The end face of the halves 3 facing the charging port is provided with an arc-shaped groove. The upper and lower arc-shaped grooves are combined to form a wiring hole. A rubber layer is installed on the inner wall of the arc-shaped groove. The upper and lower rubber layers are combined to form a sealing ring 4. A baffle 9 is provided inside the sealing shell to block the wiring hole. Multiple positioning strips 5 are installed on the upper and lower surfaces of the power bank body 1 to close the halves 3 inward.

[0022] In this embodiment, the inner side of the frame 2 is provided with multiple first positioning grooves 12, and the inner side of the half shell 3 is provided with multiple second positioning grooves that communicate with the first positioning grooves 12. One end of each positioning strip 5 passes through the first positioning groove 12 and is inserted into the second positioning groove. The end of the second positioning groove facing the frame 2 is enlarged to form an inlet / outlet groove 11 for the half shell 3 to be opened.

[0023] In this embodiment, a sliding groove 8 is provided on the outer side of the positioning strip 5, and a slider 7 is installed on the inner side of the frame 2 opposite to the sliding groove 8. The slider 7 is slidably disposed in the sliding groove 8, and a first compression spring 6 is installed between the slider 7 and the sliding groove 8.

[0024] In this embodiment, a plurality of positioning holes are provided on one side of the baffle 9, and a positioning post 10 is provided in each positioning hole. One end of each positioning post 10 extends to the outside and is installed on the half shell 3. A second compression spring is installed on the other end of each positioning post 10, and the other end of each second compression spring is installed on the inner wall of the positioning hole.

[0025] In this embodiment, one side of the baffle 9 is fitted to the inner side of the sealing shell; there can be multiple baffles, each baffle corresponding to a wiring hole. Therefore, after inserting a charging head, as long as the corresponding baffle is pressed down, the remaining baffles can still block the wiring hole to ensure the sealing effect.

[0026] In this embodiment, the cross-sections of the positioning strip 5, the first positioning groove 12, and the second positioning groove are all trapezoidal, so that the half shell can be positioned by the positioning strip, so that the half shell is in a closed state.

[0027] When not in use, the sealing shell and baffle can cover the charging port of the power bank, thus sealing the charging port and preventing dust and water from coming into contact with it, thereby reducing the probability of charging port failure.

[0028] During use, the frame and sealing shell can be pushed outward. As the sealing shell moves, the end of the positioning strip will enter the inlet / outlet groove of the half shell. At this time, the positioning strip will lose its positioning function for the half shell. The half shell can be automatically opened outward by the torsion spring hinge. After opening, the charging head can be inserted into the charging port through the opening. After insertion, the half shell can be closed. The elasticity of the second compression spring pulls the frame. The movement of the frame drives the half shell, so that the second positioning groove on the half shell can be put on the positioning strip again. The positioning strip can position the half shell, so that the half shell is in a closed state. The rebound of the second compression spring makes the inner side of the sealing shell abut against the end face of the charging head, thereby pressing the charging head tightly and preventing loosening during the charging process.

[0029] The power cord on the charging head can pass through the wiring hole, and the sealing ring increases the sealing between the power cord and the wiring hole. After the charging head is plugged into the power bank, the baffle will press down and move away from the inside of the wiring hole to avoid obstruction.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
