DETAILED DESCRIPTION

[0025] The embodiments of the present application will be described below with reference to the drawings. For the purpose of clearness, many details of the embodiments will be described in the following description. However, it should be understood that these details are not intended to limit the present application. That is, in some embodiments of the present application, these details are not necessary. In addition, for the purpose of simplicity, some conventional structures and components will be shown in the drawings in a simplified schematic manner.

[0026] In addition, the descriptions such as "first", "second" and the like in the present application are only for the purpose of description, and do not mean to particularly indicate the order or sequence, nor to limit the present application. They are merely used to distinguish components or operations described by the same technical terms, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but must be based on the realization of ordinary skilled in the art. When the combination of technical solutions contradicts each other or cannot be realized, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0027] The present embodiment provides a current conversion type charger which can quickly and effectively adjust the charging current in actual use, thereby effectively improving the charging efficiency of electronic devices and meeting the charging needs of different electronic devices.

[0028] In combination Figures 1 to 5 As shown in the drawings, the current conversion type charger of the present embodiment includes a lower shell 10, a current conversion module 20 and an upper shell 30. The lower shell 10 and the upper shell 30 are buckled to form a sealed cavity, and the current conversion module 20 is located in the sealed cavity, thereby forming the charger.

[0029] In the present embodiment, a circuit board 11 is installed in the lower shell 10, and a plurality of contact points 111 are provided on the circuit board 11. A first wiring terminal 12 and a second wiring terminal 13 are provided on the lower shell 10. The first wiring terminal 12 is a wire inlet port, and the second wiring terminal 13 is a wire outlet port. The circuit board 11 is connected to the outside through the first wiring terminal 12 and the second wiring terminal 13, thereby realizing the charging operation.

[0030] Specifically, the contact point 111 on the circuit board 11 is a soldering point, which is soldered on the surface of the circuit board 11, and the current conversion module 20 is located on the surface of the circuit board 11 and contacts the contact point 111. When the current conversion module 20 contacts the contact point 111, it indicates that the current conversion module 20 is started, which can effectively adjust the charging current, thereby effectively improving the charging efficiency of the electronic device, meeting the charging needs of different electronic devices. The current conversion module 20 is installed on the surface of the circuit board 11 by a plurality of limiting members 40, so the current conversion module 20 can be replaced, and different specifications of current conversion modules 20 can be selected according to the charging needs of different electronic devices, thereby enhancing the compatibility of the charger.

[0031] In combination Figure 2 With Figure 3 As shown in the drawings, the limiting members 40 of the embodiment are uniformly distributed outside the installation area 50 to limit and install the current conversion module 20. The limiting members 40 include limiting blocks 41 and springs 42. The end of the limiting block 41 is connected with the spring 42 to flip and press the current conversion module 20. During the installation of the current conversion module 20, the limiting block 41 is flipped, and the current conversion module 20 is flipped and pressed by the limiting block 41. The existence of multiple limiting blocks 41 presses and positions the current conversion module 20 from multiple positions, thereby stably installing the current conversion module 20.

[0032] In the embodiment, the circuit board 11 is provided with an installation area 50, and the current conversion module 20 is located in the installation area 50. The installation area 50 is formed by connecting a plurality of blocking blocks 60 to install the current conversion module 20 on the surface of the circuit board 11. The installation area 50 of the embodiment corresponds to the position of the contact point 111 on the circuit board 11, so that the installed current conversion module 20 contacts the contact point 111.

[0033] Further, the circuit board 11 of the embodiment is provided with a positioning pin 112, and the spring 42 is sleeved on the positioning pin 112 to install the spring 42, thereby facilitating the flipping and pressing operation of the limiting block 41 on the current conversion module 20, and realizing the stable installation of the current conversion module 20.

[0034] In actual use, the current conversion type charger of the embodiment has the current conversion module 20 installed on the circuit board 11, which can effectively adjust the charging current, thereby effectively improving the charging efficiency of the electronic device, meeting the charging needs of different electronic devices. The current conversion module 20 is installed on the surface of the circuit board 11 by a plurality of limiting members 40, so the current conversion module 20 can be replaced, and different specifications of current conversion modules 20 can be selected according to the charging needs of different electronic devices, thereby enhancing the compatibility of the charger.

When implemented in software, the functions can be stored on or transmitted over as one or more instructions or code on a computer-readable medium. Computer-readable media include both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another. A storage media can be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer. Also, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, or twisted pair, then the coaxial cable, fiber optic cable, or twisted pair are included in the definition of medium. Disk and disc, as used herein, include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), and Blu-Ray® disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above should also be included within the scope of computer-readable media.
