Description

Electronic device lock structure

The present invention relates to a latching structure for an electronic device, and more particularly to a latching structure for guiding a storage body to be inserted and withdrawn.

Electronic devices often have a memory bank to expand the storage capacity of the electronic device because of the small space stored therein. The storage body is generally held by a latch structure inside the electronic device and electrically connected to the connector in the electronic device. Such a storage medium is more commonly a TIF (Tagged Image File Format) card, an SD (Secure Digital Memory Card) card, or even a small mobile device (such as a small mobile phone) compatible with the electronic device.

In the conventional card lock structure, the storage body is inserted into the electronic device, which is manually extracted, which causes inconvenience in operation. At present, a card-removing method (commonly known as Push-Push) that repeatedly presses the storage body and causes the storage body to exit is designed, which greatly facilitates the operation of the user. Most of the internal structure of the card lock structure is designed with a card type cam, such as the memory card card return structure of Taiwan Taiwan No. 547834, which is a typical Push-Push card card design, which is generally inserted into the electronic card by using a memory card. After the jack of the device, the slider is connected to perform a stroke like "heart type", and the positioning and position restoration effect are generated by the contour of a heart-shaped cam and the spring force of the spring, so that the memory card is pushed out of the jack after being pushed again.

The latch structure solves the problem of inconvenience to the user, but uses a cam setting. The structure is complicated, which is not conducive to manufacturing, and is not conducive to miniaturization of electronic devices.

In view of the above, it is necessary to provide a card lock structure of an electronic device which is simple in structure and convenient to manufacture.

The latching structure of the electronic device is configured to hold a receiving member in the electronic device and elastically withdraw the receiving member, the latching structure comprising a main body, a receiving frame, a holding body and an elastic member; The main body has a bottom plate and two first side walls, and a plurality of guiding walls are formed on the bottom plate; a guiding body is formed on one side of the guiding wall, and a plurality of clamping holes are formed in the side wall of the receiving frame, and the guiding wall is The guiding body cooperates with the clamping hole on the receiving frame; the holding body elastically abuts between the first side wall of the main body and the guiding wall; one end of the elastic member is connected to the main body The other end is connected to the receiving frame; the receiving member is pushed, and the receiving member moves together with the receiving frame until the holding body protrudes from the clamping hole and engages with the receiving member. The receiving member is clamped in the electronic device, and the receiving member is pushed again. Under the pulling force of the elastic member, the receiving frame presses the holding body to disengage the holding body from the receiving member. In order to withdraw the receiving member.

Compared with the conventional latching structure, the present invention enables the receiving member to be housed in the electronic device under the action of the first external force by the cooperation of the body, the receiving frame, the retaining body and the elastic member, and pushes the electronic device again. The receiving member can elastically bounce from the electronic device when the member is received The invention has the advantages of simple operation and convenient manufacture, and does not need to adopt a more complicated cam structure, so that the overall structure of the card lock structure is simple, the manufacture is convenient, and the miniaturization design of the electronic device is facilitated.
