Description

2-in-1 SIM card tray and volume button

This patent application claims the benefit of U.S. Patent Application Serial No. PCT/CN2017/070215, filed on Jan. 5,,,,,,,,,,,, The content is explicitly incorporated herein.

In summary, the present content relates to electronic devices and, more particularly, to a holding tray assembly having integrated control keys.

Electronic devices such as cellular phones, tablets, media players, cameras, etc. often require a SIM card and/or storage module. The SIM card stores user account information associated with the device, which is used by the communication network to configure and control device access to the network. The storage module expands the device storage space for storing photos, videos and music. One of the commonly used storage modules is a security device (SD) card, which can include various form factors, such as a micro SD.

Traditionally, SIM cards and storage modules can be placed under the battery cover. The user has to open the battery cover to access the SIM card and the storage module, which may be inconvenient and easily expose the interior of the device to danger. Alternatively, the SIM card and storage module can be inserted into separate slots in the device housing, which can reduce the integrity of the device housing and increase manufacturing costs.

A method for an electronic device, comprising the steps of: securing one or more cards in a recess of the electronic device using a support tray; and covering the recess with an external controller, the external controller being A function configured to control the electronic device, wherein the external controller is movably coupled to the support tray via at least one locating post. The method of claim 23, wherein the support tray is secured within the recess by pushing the external controller inwardly until the support tray is locked in a closed position. The method of claim 23, wherein the external controller includes a tool receiver opening for receiving a needle, and wherein the needle is passed through the tool receiver opening inwardly until the support tray is locked in a closed position The support tray is fixed inside the recess. The method of claim 23, wherein the external controller includes a tool receiver opening for receiving a needle and passing the needle through the tool receiver opening by inward pushing until the support tray is released to a portion of the open position, The support tray is ejectable from the electronic device. The method of claim 23, wherein the one or more cards comprise at least one of a Subscriber Identity Module (SIM) card and a memory card. The method of claim 23, wherein each of the at least one positioning post is engaged with a corresponding positioning hole of the external controller such that when the support tray is locked in a closed position inside the electronic device A gap is allowed between the external controller and an edge of the support tray closest to the external controller, the gap allowing the external controller to move. An apparatus for an electronic device, comprising: a unit for securing one or more cards in a recess of the electronic device using a support tray; and a unit for covering the recess with an external controller The external controller is configured to control a function of the electronic device, wherein the external controller is movably coupled to the support tray via at least one positioning post. A device according to claim 29, wherein each of the at least one positioning post is engaged with a corresponding positioning hole of the external controller such that when the support tray is locked in a closed position inside the electronic device A gap is allowed between the external controller and an edge of the support tray closest to the external controller, the gap allowing the external controller to move.
