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 steps in all methods or processes disclosed herein, 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 modular expandable power bank, including a power bank body 1 and an end plate 2. The end plate 2 has a positioning part 3 protruding from the middle. The inner side of the end plate 2 is provided with a cavity 14 that matches the charging head at the charging port of the power bank body 1. The surface of the end plate 2 is provided with a wiring channel 4 that communicates with the cavity 14. The power bank body 1 has positioning grooves 10 on both sides. Positioning plates 5 are installed at both ends of the end plate 2. The other end of the positioning plates 5 is inserted into the positioning grooves 10. The end of the positioning plates 5 away from the end plate 2 protrudes to form a limiting part 6. The surface of the power bank body 1 is provided with a U-shaped groove 12 that communicates with the positioning grooves 10. The inside of the U-shaped groove 12 is provided with a U-shaped frame 7 for limiting the positioning plates 5.
[0022] In this embodiment, the inner side of the opening of the positioning groove 10 is provided with a groove, and the opening of the groove is provided with a limiting block 11. One end of the limiting block 11 extends into the positioning groove 10 and is in contact with the side of the positioning plate 5. The other end of the limiting block 11 is equipped with a first compression spring, and the other end of the first compression spring is installed on the inner wall of the groove. The limiting block 11 and the limiting part 6 are arranged laterally opposite each other.
[0023] In this embodiment, multiple positioning holes are vertically provided on the inner wall of the U-shaped groove 12. The positioning holes avoid the battery inside the power bank body 1. Positioning posts 13 are installed on the inner side of the U-shaped frame 7 opposite to the positioning holes. The other end of the positioning posts 13 is inserted into the positioning holes and a second compression spring is installed on each of them. The other end of the second compression spring is installed on the inner wall of the positioning hole.
[0024] In this embodiment, an operation slot 8 is provided in the middle of the U-shaped groove 12, and a triangular insertion slot 9 is provided in the U-shaped frame 7 opposite to the operation slot 8. The outer surface of the U-shaped frame 7 is flush with the outer surface of the power bank body 1 to ensure the flatness of the outer surface of the power bank body.
[0025] In this embodiment, both ends of the U-shaped frame 7 are abutted against the limiting part 6, so that the U-shaped frame can block the positioning plate and prevent the end plate from moving outward and affecting the protection of the charging head.
[0026] In this embodiment, the end plate 2 is made of insulating plastic material, which avoids short circuits caused by conductivity and increases safety.
[0027] When charging is needed, first insert your finger into the insertion slot along the operating groove, and lift the U-shaped frame upwards so that the U-shaped frame rises along the positioning hole. After the U-shaped frame moves out of the positioning groove, the end plate can be pushed outwards so that the charging head can be inserted into the charging port of the power bank body. The power cord on the charging head can extend to the outside along the wiring channel. After the end plate moves towards the power bank body, the charging head can enter the mold cavity. The mold cavity can press the charging head tightly onto the power bank body to prevent loosening. As the positioning plate returns to its original position, both ends of the U-shaped frame can be inserted into the positioning groove again and abut against the limiting part, thereby positioning the end plate and the charging head. The end plate can cover the outside of the charging head. Once it is hit, its impact force can also be applied to the power bank body through the end plate and the positioning plate, avoiding damage caused by the impact on the charging head and charging port.
[0028] When the end plate is damaged or needs to be replaced, the limiting block can be squeezed and retracted into the groove. After the limiting block is removed, the positioning plate can be taken out through the opening of the positioning groove, which facilitates the replacement of the end plate.
[0029] 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.
