Chip card holding mechanism and portable electronic device having the same

The present invention relates to a holding mechanism for accommodating and holding a wafer card and a portable electronic device having the same.

As the functions of portable electronic device products become more and more diversified, more and more chip cards for implementing different functions such as storage and communication on the portable electronic device, such as an SD card (Secure Digital Memory Card) and a CF card, are increasingly used. (Compact Flash Card), SIM card (Subscriber Identification Module Card), etc.

In order to accommodate and install the above-mentioned wafer card, the card housing space of the wafer card and the card holding mechanism must be preset in the portable electronic device to fix the wafer card in the portable electronic device. A conventional wafer card holding mechanism includes an outer cover, a rotating shaft, and a spring piece disposed at the bottom of the card accommodating space in the portable electronic device. The wafer card is mounted in the card accommodating space and elastically resists the elastic piece. The cover is hinged to the body of the portable electronic device by the rotating shaft and correspondingly engaged with the body of the portable electronic device to fix the wafer card in the card accommodating space together with the elastic piece. When the user needs to replace the wafer card, the cover is hinged to the outer cover of the portable electronic device, so that the outer cover rotates around the rotating shaft, and the wafer card is ejected by the elastic resisting force of the elastic piece. By adopting the above-mentioned wafer card holding mechanism, when the user picks up the wafer card and pulls off the outer cover, the force is too small. It cannot be unlocked. When the force is too strong, the rotating shaft is easily damaged, which makes it extremely inconvenient for the user to pick up and place the wafer card. In addition, after the cover is opened, the wafer card is ejected, and the wafer card is easily ejected due to misoperation, resulting in data loss.

In view of the above, it is necessary to provide a wafer card holding mechanism that is convenient for handling a wafer card and that is not easily mishandled.

At the same time, it is also necessary to provide a portable electronic device having the wafer card holding mechanism.

A wafer card holding mechanism includes a base, an elastic member, a snap assembly and a tray. A receiving space for the receiving opening is formed in the base. The elastic member is mounted on the base and partially accommodated in the receiving space. The snap component is movably mounted on the base. A wafer card carrying space is recessed on the tray, and two card slots are respectively recessed on two sides of the tray. The engaging component comprises two hooks, an elastic member connecting the two hooks, and two card blocks. The two card blocks are respectively protruded from one end of each hook and cooperate with the corresponding card slot. The tray is slidably mounted on the base, and is engaged in the receiving space of the base by the card block and the card slot and elastically resists the elastic member.

A portable electronic device includes a housing and a wafer card holding mechanism installed in the housing. A socket is opened in the housing. The wafer card holding mechanism includes a base, an elastic member, a snap assembly, and a tray. The base is fixedly mounted in the housing. A receiving space for the receiving opening is formed in the base, and the receiving opening corresponds to the socket on the housing. The elastic member is mounted on the base and partially accommodated in the receiving space. The snap component is movably mounted on the base. A wafer card carrying space is recessed on the tray, and two card slots are respectively recessed on the two sides of the tray. The engaging component comprises two hooks, an elastic member connecting the two hooks, and two card blocks. The two card blocks are respectively protruded from one end of each hook and cooperate with the corresponding card slot. Tray can slide The device is mounted on the base and is inserted into the receiving space of the base by the card block and the card slot and elastically resists the elastic member.

The wafer card holding mechanism fixes the tray by using the engaging component that engages with the tray and the elastic member that elastically resists the tray, thereby fixing the wafer card carried in the tray. The engaging force applied by the engaging component and the abutting force applied by the elastic member together hold the tray, so that the reliability is strong, and the electrical connection failure of the wafer card can be effectively avoided. When the tool is used to unlock the engaging component, the elastic member resists the tray to slide the tray out to take the wafer card, which is convenient to operate and can prevent misoperation and loss of data.
