Description

Detachable connection device for mobile phones supporting wireless charging The invention relates to a detachable mobile phone coupling device comprising a grip device that receives power through a stand and performs wireless charging of the mobile phone. Wireless charging technology for mobile phones transmits power based on the principle of electromagnetic induction, generating an electric current through the interaction between the charging pad and the coil inside the mobile phone. When current flows through the charging pad, a magnetic field is generated, and the mobile phone's coil receives this magnetic field and converts it into electrical energy to charge the battery. Wireless charging technology is convenient as it does not require a physical connection, and it has the advantages of preventing damage to the charging port and maintaining water and dust resistance. However, wireless charging technology requires a short physical distance between the charging pad and the mobile phone's coil for efficient charging. Consequently, if accessories such as a grip are attached to the mobile phone, the distance between the charging pad and the coil increases, weakening electromagnetic induction. This can lead to a significant decrease in charging efficiency or even make charging impossible. FIG. 1 is a configuration diagram of a detachable coupling device for a mobile phone according to one embodiment. FIGS. 2 and FIGS. 3 are illustrative diagrams for explaining the configuration of a grip device according to one embodiment. FIG. 4 is an illustrative diagram for explaining the configuration of a stand according to one embodiment. Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings. In describing the present invention, specific descriptions of related known functions or configurations will be omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the present invention. Furthermore, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intentions or conventions of the user or operator. Therefore, their definitions should be based on the content throughout this specification. Hereinafter, embodiments of a detachable mobile phone coupling device and method will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of a detachable coupling device for a mobile phone according to one embodiment. According to one embodiment, the mobile phone detachable coupling device (10) may include a grip device (100) having a coil for wireless charging at a lower portion (110) attached to a mobile phone or mobile phone case, and a mounting portion (210) having a groove (211) into which a part of the grip device (100) is inserted, and a mounting portion (210) including a pin (215) configured as a pair to supply power to the coil. For example, the grip device (100) includes a coil for wireless charging and a contact pad for electrical connection, and the contact pad is composed of two circular rings so that power can be stably transmitted even when mounted at various angles. The stand (200) may include a groove into which a part of the grip device is inserted and a pin that supplies power to the wireless charging coil. For example, power from an external power source is input to the stand terminal, and power can be transmitted in the order of the stand, the mounting pin, the contact pad, and the coil. Accordingly, the user can wirelessly charge the mobile phone without removing the grip device while the phone is mounted. According to one embodiment, the grip device (100) may further include a bellows-shaped expandable portion (120) installed between the top of the lower portion (110) and the bottom of the upper portion (130), and an upper portion (130) installed at the top of the expandable portion (120). Through this, the grip device (100) can be folded and unfolded in a folded shape through the bellows-shaped expandable portion (120). According to one example, the upper portion (130) and the extendable portion (120) can be inserted into a groove (211) provided in the mounting portion (210). For example, the diameter of the groove (211) is larger than the diameter of the upper portion (130) or the extendable portion (120), and the depth can be deeper than the sum of the lengths of the upper portion (130) and the extendable portion (120) when the extendable portion (120) is folded. Through this, the upper portion (130) and the extendable portion (120) can be inserted into the groove (211), and the side wall (213) of the mounting portion (210) can come into contact with the lower portion (110). FIGS. 2 and FIGS. 3 are illustrative diagrams for explaining the configuration of a grip device according to one embodiment. According to one embodiment, the lower portion (110) may include a first magnet for attaching to a
