Description

Electronic device with expansion card protection

technical field

The present invention relates to an electronic device, and in particular to an electronic device capable of protecting an expansion card stored therein.

Background technique

Most of the miniaturized electronic devices currently on the market, such as personal digital assistants (PDAs), mobile phones, and portable multimedia players, have the function of supporting expansion of memory cards to store more data. However, since most electronic devices use a push-push connection mechanism to fix the memory card, the memory card can be inserted and removed by pressing with a finger, and there is no special protection function designed to make the memory card stolen risk is high.

Contents of the invention

In view of this, the object of the present invention is to provide an electronic device with an expansion card protection function, which utilizes an electromagnetic switch in combination with a software program to implement the control function, and cooperates with the mechanism design to realize the function of protecting the expansion card (such as a memory card).

According to the object of the present invention, an electronic device is proposed, which includes a body, a cover, an electronic switch, an input interface and a control unit. The main body stores a preset password, and the cover plate is arranged on the main body in an openable and closable manner. The electronic switch is disposed on the body to lock or release the cover, and the electronic switch locks the cover when the electronic device is not powered on. The input interface is set on the body, and is used for inputting an opening password. The control unit is electrically connected to the input interface and the electronic switch respectively, and the control unit is arranged in the body to receive the opening password and obtain the preset password. When the opening password matches the preset password, the control unit controls the electronic switch to release the cover.

In order to make the above objects, features, and advantages of the present invention more comprehensible, a preferred embodiment is specifically cited below, and is described in detail in conjunction with the accompanying drawings as follows:

FIG. 3 is a schematic diagram of an open state of a cover of an electronic device according to a preferred embodiment of the present invention.

Detailed ways

Please refer to FIG. 1 , which is a block diagram illustrating a memory card protection function of an electronic device according to a preferred embodiment of the present invention. The electronic device 100 of this embodiment may be a mobile phone, a personal digital assistant, a smart phone or a portable multimedia player. The electronic device 100 includes a body 110 , a cover 120 , an electronic switch 130 , an input interface 140 and a control unit 150 . Please also refer to FIG. 2 , which shows a schematic diagram of a closed state of the cover of an electronic device according to a preferred embodiment of the present invention. The main body 110 stores a preset password and has an electrical slot 112 , such as a memory slot, and the cover 120 is disposed on the main body 110 in an openable and closable manner. When the cover 120 is in a closed state, the cover 120 shields the electrical socket 112 . The electronic switch 130 is disposed on the body 110 to lock or release the cover 120 . When the cover 120 is closed, the electronic switch 130 locks the cover 120 when the electronic device 100 is not powered on.

The input interface 140 is disposed on the main body 110 for inputting an unlock password, such as a key device of a mobile phone, or an external keyboard of a personal digital assistant, and the like. The control unit 150 is electrically connected to the input interface 140 and the electronic switch 130 respectively, and the control unit 150 is disposed in the main body 110 to receive the unlock password and obtain the preset password. When the opening password matches the preset password, the control unit 150 controls the electronic switch 130 to release the cover plate 120 . When the opening password does not match the preset password for a set number of times, preferably the control unit 150 can be set to lock the electronic switch 130 so that it cannot be opened by inputting the opening password, so as to ensure the safety of the memory card. In addition, the electronic device 100 also includes a display component 160 , such as a liquid crystal display or a light-emitting diode display screen, for displaying the entered password, so that the user can input and modify the password.

As shown in FIG. 2 , the cover plate 120 also has a first engaging portion 122 , and the electronic switch 130 further includes a locking component 132 and an electromagnetic component 134 . The locking component 132 is slidably disposed in the body 110 . The locking component 132 has a first end and a second end, and the first end has a second engaging portion 132 a. When the first joint portion 122 interferes with the second joint portion 132a, the cover plate 120 is locked with the main body 110 . The electromagnetic component 134 is disposed on the body 110 .

The locking component 132 also has a protruding block 132b and a pin 132c, and the pin 132c is connected to the protruding block 132b. The second end of the locking component 132 is located on the pin 132c, and the first end of the locking component 132 is located on the other side of the protrusion 132b relative to the pin 132c. In this embodiment, it is more preferable to include an elastic component 133 inserted into the pin 132c, and a baffle 135 fixed on the body 110 . The pin 132c is inserted into the blocking plate 135 and can move relative to the blocking plate 135. The elastic component 133, such as a spring, is located between the blocking plate 135 and the protrusion 132b.

In this embodiment, the first engaging portion 122 has a slot, and the second engaging portion 132a has a protruding portion, so that the first engaging portion 122 and the second engaging portion 132a can interfere. Wherein, the protruding portion can also be preferably designed to have a rounded corner, so that when the cover plate 120 is pressed down and contacts the rounded corner, a lateral component force can be generated on the second joint portion 132a, so that the protrusion 132b moves backward. Retracting, the elastic component 133 abuts against the baffle 135 to generate an elastic stress correspondingly. When the protruding portion of the second engaging portion 132 a reaches the slot of the first engaging portion 122 , the elastic stress generated by the elastic component 133 pushes the protruding portion into the slot, thereby fixing the cover plate 120 and the body 110 . However, the present invention is not limited thereto, and the first engaging portion 122 may also have a protrusion, while the second engaging portion 134a may have a slot.

Please refer to FIG. 3 , which is a schematic diagram of an open state of a cover of an electronic device according to a preferred embodiment of the present invention. When the electromagnetic component 134 is turned on, a magnetic attraction force will be generated due to electromagnetic action to attract and move the second end of the locking component 132, that is, to attract the plug 132c to separate the first joint part 122 and the second joint part 132a to open. cover plate 120 . The pin 132c is a magnetizable material, such as iron or nickel. In this embodiment, the pin 132c and the bump 132b are preferably integrally formed. Since one end of the cover plate 120 is pivotally connected to the body 110 by the pivot portion 114 , a torsion spring 116 is disposed on the body 110 adjacent to the end. When the electronic switch 130 is turned on, the cover 120 is opened relative to the main body 110 by the elastic force of the torsion spring 116 .

In the electronic device disclosed in the above embodiments of the present invention, an appropriate protection mechanism is designed to protect the memory card by means of an electronic switch and password input. Since the acting force is electromagnetic force, the password must be input to open the protection device when the power is turned on, which can ensure the safety of the memory card.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make various equivalents without departing from the spirit and scope of the present invention. Changes and modifications, so the protection scope of the present invention should be defined by the claims.
