Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figures 1-5 This is an embodiment of the present invention, which provides a foldable portable charger, comprising:

[0028] The support assembly 100 includes a protective shell 101, an inner liner 102 fixedly installed in the inner cavity of the protective shell 101, a reserved opening 103 at the bottom of the inner liner 102, a mounting groove 104 provided on the side wall of the inner liner 102, and a mounting assembly 105 provided in the inner cavity of the inner liner 102.

[0029] The charging assembly 200 includes a connector 201 fixedly installed on the side wall of the inner liner 102, a connector 202 fixedly installed in the inner cavity of the connector 201, a terminal block 203 slidably installed on the inner wall of the connector 202, a pin 204 movably connected to the surface of the terminal block 203, a synchronous shaft 205 fixedly installed on the side wall of the pin 204, and a conversion assembly 206 disposed in the inner cavity of the inner liner 102 for use with the pin 204.

[0030] Specifically, the mounting assembly 105 includes a mounting base 105a fixedly mounted on the side wall of the inner liner 102, and a storage groove 105b formed on the side wall of the mounting base 105a. The mounting assembly 105 also includes a mounting block 105c fixedly mounted on the side wall of the mounting base 105a, and a protective shell 105d connected to the side wall of the mounting base 105a.

[0031] Furthermore, the protective shell 105d is designed to prevent damage to the internal circuitry of the charger from impacts or vibrations during use, which could cause open or short circuits in the internal wires and affect the charger's operation. The connector 202 is made of conductive metal and has an internal spring that limits the movement of the pin 204 when it rotates and provides conductivity when the pin 204 is connected to the power supply.

[0032] The conversion assembly 206 includes a converter 206a fixedly installed on the inner wall of the inner liner 102, and a connecting line 206b electrically connected to the side wall of the converter 206a. The conversion assembly 206 also includes a storage shaft 206c movably connected to the side wall of the connecting line 206b, and a fixed shaft 206d connected to the side wall of the storage shaft 206c via a bearing. The conversion assembly 206 also includes a winding spring 206e fixedly installed on the side wall of the fixed shaft 206d, and an interface 206f electrically connected to the end of the connecting line 206b.

[0033] Preferably, the connecting wire 206b is wound around the surface of the take-up spool. When in use, pulling the interface 206f can pull out the connecting wire 206b. When not in use, the take-up spring 206e will drive the take-up spool to rotate and retract the connecting wire 206b.

[0034] It should be noted that the side wall of the housing 105d is fixedly connected to the inner wall of the mounting groove 104, the pin 204 is movably connected to the inner wall of the storage groove 105b, the synchronous shaft 205 is movably connected to the inner cavity of the mounting block 105c, and the converter 206a is connected to the connector 202 via a wire.

[0035] In use, by moving the pin 204, the pin 204 rotates the synchronous shaft 205, pulling the pin 204 out of the storage slot 105b. The spring in the connector 202 pushes the terminal 203, and the terminal 203 presses against the pin 204. The pin 204 is then inserted into the power strip to connect to the power supply. The pin 204, through the terminal 203 and the connector 202, transmits electrical energy to the converter 206a, which converts the voltage to a compatible battery voltage. After the power is supplied, the connecting wire 206b is inserted into the interface 206f. When charging the battery, the interface 206f is pulled, and the interface 206f drives the connecting wire 206b to extend outward from the reserved port 103. The battery is charged through the interface 206f. After charging is completed, the interface 206f is released, and the fixed shaft 206d, together with the winding spring 206e, drives the winding shaft to rotate. The rotation of the winding shaft rewinds the connecting wire 206b onto the surface of the winding shaft.

[0036] In summary, an efficient and convenient charging experience is achieved. By manually flipping the plug 204, it smoothly pops out of the storage slot 105b, allowing the plug 204 to be folded and stored when not in use, reducing the size of the charger. This foldable plug 204 design not only ensures the charger's compactness when carried but also allows it to be quickly unfolded for easy power connection. The connection cable 206b makes it easy for users to put the charger in their bags without taking up too much space. At the same time, it can quickly switch from the stored state to the working state when charging is needed, making it convenient for users.

[0037] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered.
