Patent Description:
With the growth of digital technologies, a great variety of electronic devices such as a mobile communication terminal, a smart phone, a tablet personal computer (tablet PC), a notebook, a personal digital assistant (PDA), a wearable device, or a digital camera have been developed and are now in widespread use.

These electronic devices allow for insertable/extractable components such as an external memory card, a subscriber identity module (SIM) card, and a digital pens.

In particular, recent trends have sought for an increased content storage capacity in the electronic devices, and greater operational speeds. Accordingly, an external memory card having improved capacity and read/write speeds have been developed. Thus, users now more commonly utilize external memory cards, such as solid state drives (SSD), which in turn increases the demand for data security for accessing information stored in the external memory card.

<CIT> discusses an interface device for electronic equipment which is provided in the electronic equipment to electrically connect the electronic equipment to an external device. <CIT> discusses a camera lens cover device formed in a mobile apparatus. <CIT> discusses a video communication system and method for controlling the same to automatically and manually open and close a camera.

The insertable/extractable components (e.g., or a component tray containing the component) may be inserted into a designated port (i.e.. , or an opening) of the electronic device. In addition, the component may be extracted through a physical extraction functionality, such as pressing an ejection button of the component, or accessing an ejection function through a hole in or adjacent to the component tray, using a small, thin tool.

However, these physical extraction methods allow extraction purely by application of physical force without requiring any kind of user authentication. Accordingly, these components are vulnerable to being taken by non-secure persons, and the security of the data may thereby be compromised.

The disclosure is to provide an electronic device capable of opening or closing an opening thereof, into which a component is insertable, through a slide door that is automatically opened and closed under predetermined conditions.

According to certain embodiments, the electronic device may open or close the slide door to open or close the opening when a predetermined condition is satisfied. In particular, based on the linear movement of the link in accordance with the driving operation of the driving actuator, the electronic device can open the opening easily and automatically by releasing the forcible open blocking of the forcible open blocker and moving the slide door without requiring any further operation. In addition, based on the linear movement of the link in accordance with the driving operation of the driving actuator, the electronic device can close the opening by moving the slide door and also enable the forcible open blockerto effectively block the forcible open of the slide door. This is advantageous to enhancing the security of components that can be inserted into the opening.

Hereinafter, embodiments of the disclosure will be described in detail with reference to accompanying drawings.

<FIG> is a perspective view <NUM> illustrating an appearance of an electronic device <NUM> according to certain embodiments.

According to certain embodiments, the electronic device <NUM> may include a housing <NUM> and an opening <NUM> formed inwardly from one surface of the housing <NUM>. The opening <NUM> allows a component to be inserted or extracted.

According to certain embodiments, the opening <NUM> may be opened or closed in accordance with an opening or closing operation of a slide door <NUM>.

For example, the opening <NUM> may be closed by the slide door <NUM> as shown in <FIG>. Also, the opening <NUM> may be opened by moving the slide door <NUM> laterally, and thus exposed to the outside.

The electronic device <NUM> according to certain embodiments may control the slide door <NUM> to be automatically opened or closed using a driving actuator disposed inside the electronic device <NUM>. Through this, the opening <NUM> can be opened or closed.

For example, when the user wants to insert or extract a certain component into or from the opening <NUM>, the electronic device <NUM> may open the slide door <NUM> to open the opening <NUM>, based on a user input.

For example, the electronic device <NUM> may close the slide door <NUM> to close the opening <NUM> after the user inserts or extracts the component into or from the opening <NUM>. Alternatively or additionally, the electronic device <NUM> may control the slide door <NUM> to be automatically closed after the elapse of a predetermined time from the open of the slide door <NUM> or in response to a user input.

According to certain embodiments, components insertable into the opening <NUM> opened and closed by the slide door <NUM> may include an external memory card or a SIM card that can be recognized by the electronic device <NUM>. According to another example, such components may include a digital pen that supports an input function of the electronic device <NUM>.

According to certain embodiments, the electronic device <NUM> may open or close the slide door <NUM>, based on an external input signal. For example, the electronic device <NUM> may receive the external input signal through an input module (e.g., the input device <NUM> in <FIG>) or a communication module (e.g., the communication module <NUM> in <FIG>) of the electronic device <NUM>.

For example, the external input signal may include a user input. For example, the electronic device <NUM> may identify whether the user input satisfies a predetermined authentication condition, and based on the identification result, control the slide door <NUM> to be opened or closed. According to an embodiment, the electronic device <NUM> may identify whether the received external input signal (e.g., the user input) meets the predetermined authentication condition. Then, if it is determined that the external input signal meets the authentication condition (i.e., successful authentication), the electronic device <NUM> may operate the driving actuator to control the slide door <NUM> to be opened or closed. The external input signal may include user's biometric information such as fingerprint information, iris information, or face shape information. For example, the electronic device <NUM> may obtain the external input signal including the biometric information by using a camera module thereof.

According to another embodiment, the external input signal may include a power supply control signal for the electronic device <NUM>. For example, if it is determined, based on the power supply control signal, that the system power supply to the electronic device <NUM> is stopped, the electronic device <NUM> may operate the driving actuator to control the slide door <NUM> to be automatically closed.

According to still another embodiment, the external input signal may include a physical input signal created by pressing a physical key or button provided in the electronic device <NUM>.

According to certain embodiments, when controlling the driving actuator to open or close the slide door <NUM>, the electronic device <NUM> may display movement state information of the slide door <NUM> on a display thereof.

<FIG> are diagrams illustrating an operation of moving a slide door <NUM> to open an opening <NUM> in a slide door driving environment <NUM> of an electronic device <NUM> according to certain embodiments.

Referring to <FIG>, the electronic device <NUM> includes an opening <NUM> formed on one surface of the housing <NUM>. The opening <NUM> is closed from the outside by movement of the slide door <NUM> as shown in <FIG>, and is opened through another movement of the slide door <NUM>, and thereby exposed to an exterior of the device, which is at least in partly shown in <FIG>.

According to certain embodiments, the electronic device <NUM> includes a driving actuator <NUM> and a link <NUM> connected to the driving actuator <NUM>, which linearly moves in accordance with a driving operation of the driving actuator <NUM>. The link 212is also connected to the slide door <NUM>. The link <NUM> moves the slide door <NUM> connected to the link <NUM> by a linear movement of the link <NUM>. According to an embodiment, the slide door <NUM> is disposed to engage with a ring-like portion formed at one end of the link <NUM> and moves together with the link <NUM>.

For example, when the driving actuator <NUM> is operated by a processor (e.g., the processor <NUM> in <FIG>) of the electronic device <NUM>, the link <NUM> may linearly move in accordance with the driving operation of the driving actuator <NUM>. The slide door <NUM> may also move based on the linear movement of the link <NUM>.

According to certain embodiments, the electronic device <NUM> further includes a forcible open blocker <NUM>. The forcible opening blocker <NUM> blocks (e.g., restrict or prevent) an opening of the slide door <NUM> when the opening <NUM> is closed by the slide door <NUM>. In certain embodiments, when the link <NUM> is linearly moved in accordance with the driving operation of the driving actuator <NUM>, the blockage of the opening of the slide door <NUM> by the forcible open blocker <NUM> is released, based on the linear movement of the link <NUM>.

According to certain embodiments, the electronic device <NUM> may further include a guide rail <NUM> disposed on and/or under the slide door <NUM>, to guide movement of the slide door <NUM> when the slide door <NUM> moves in accordance with the movement of the link <NUM>.

Referring to <FIG>, in the electronic device <NUM>, the opening <NUM> included in the housing <NUM> is closed by the slide door <NUM>.

The electronic device <NUM> may whether to open or close the slide door <NUM>, based on an external input signal, and may control the slide door <NUM> according to the identification result. For example, the electronic device <NUM> may identify, through a processor (e.g., the processor <NUM> in <FIG>), whether to open the opening <NUM> that is presently closed by the slide door <NUM>.

For example, when determining that the external input signal meets a condition for opening the opening <NUM>, the processor <NUM> of the electronic device <NUM> may operate the driving actuator <NUM> such that the link <NUM> moves in a first direction (e.g., a direction in which the link <NUM> is away from the opening <NUM> as shown in <FIG>).

Referring to <FIG>, when the link <NUM> moves in the first direction in accordance with the driving operation of the driving actuator <NUM>, a protruding portion <NUM> formed on one surface of the link <NUM> pushes upwards against the forcible open blocker <NUM> in a direction perpendicular to the first direction in which the link <NUM> moves. As a result, the forcible open blocker <NUM> moves from a first position of blocking the opening of the slide door <NUM> (e.g., the position of the forcible open blocker <NUM> shown in <FIG> and <FIG>), to a second position which permits release of the blockage of the opening (e.g., the position of the forcible open blocker <NUM> shown in <FIG> and <FIG>).

When the forcible open blocker <NUM> is located at a position where the opening of the slide door <NUM> is blocked, the slide door <NUM> is caught by the forcible open blocker <NUM> and thereby blocked from being opened. In addition, when the forcible open blocker <NUM> is located at a position where the blockage of the opening is released, the slide door <NUM> is freely opened or closed without obstruction by the forcible open blocker <NUM>.

Referring to <FIG> and <FIG>, when the driving actuator <NUM> is operated to open the opening <NUM> and the link <NUM> moves in the first direction, the slide door <NUM> move togethers with the link <NUM> to open the opening <NUM>.

For example, when the slide door <NUM> moves to open the opening <NUM> by the movement of the link <NUM>, the slide door <NUM> may move along the guide rail <NUM> at least partially along an inward direction of the electronic device <NUM> and at least partially in the first direction (i.e., a moving direction of the link <NUM>).

The forcible open blocker <NUM> of the electronic device <NUM> includes an elastic member that provides an elastic force for the forcible open blocker <NUM> to return to an earlier position re-blocking the opening, when a pushing pressure of the protruding portion <NUM> of the link <NUM> is released. As shown in <FIG> and <FIG>, when pressure is no longer applied (e.g., no pushing pressure) by the protruding portion <NUM> of the link <NUM>, the forcible open blocker <NUM> is located at the position of blocking the forcible open of the slide door <NUM>, and thereby prevent the slide door <NUM> from being forcibly opened.

<FIG> are diagrams illustrating an operation of a forcible open blocker <NUM> blocking a forcible open of a slide door <NUM> in accordance with a movement of a link <NUM> in an electronic device <NUM> according to certain embodiments.

<FIG> is an exploded perspective view <NUM> showing a structure of the forcible open blocker <NUM> that is pushed in accordance with the movement of the link <NUM> in the electronic device <NUM> according to certain embodiments.

Referring to <FIG>, the link <NUM> connected to the driving actuator <NUM> moves linearly in accordance with the driving operation of the driving actuator <NUM>. The link <NUM> includes a protruding portion <NUM> which pushes the forcible open blocker <NUM> and a ring-like portion <NUM>, formed to engage with the slide door <NUM>.

hen the link <NUM> moves linearly in a first direction (e.g., a direction in which the link <NUM> is away from the opening <NUM>) or in a second direction opposite to the first direction by the driving actuator <NUM>, the protruding portion <NUM> pushes the forcible open blocker <NUM> in a direction (e.g., indicated by ① in <FIG>) perpendicular to the first or second direction. For example, the forcible open blocker <NUM> may be disposed adjacent to the protruding portion <NUM> of the link <NUM>, and is at least partially moved in the direction ① as shown in <FIG> by a pushing pressure of the protruding portion <NUM>.

When the pushing pressure of the protruding portion <NUM> is released, the forcible open blocker <NUM> returns to the direction opposite to the direction ①.

The forcible open blocker <NUM> includes an elastic member <NUM>. For example, as shown in <FIG>, the electronic device <NUM> may have therein a plate <NUM> for mounting the forcible open blocker <NUM> and the elastic member <NUM>. Based on the respective structures of the plate <NUM>, the forcible open blocker <NUM>, and the elastic member <NUM>, the forcible open blocker <NUM> returns to an original position (i.e., a position before the pushing pressure is applied) when the pushing pressure of the protruding portion <NUM> is released.

<FIG> is a perspective view showing a state <NUM> in which an opening of a slide door <NUM> is blocked by a forcible open blocker <NUM> in an electronic device <NUM> according to certain embodiments.

Referring to <FIG>, in the state where the forcible open of the slide door <NUM> is blocked, that is, in the state where the pushing pressure of the protruding portion <NUM> is not applied to the forcible open blocker <NUM>, the slide door <NUM> engages with the forcible open blocker <NUM> and thereby is not moved.

<FIG> is a perspective view showing a state <NUM> in which a forcible open blocking operation of a forcible open blocker <NUM> is released in an electronic device <NUM> according to certain embodiments.

Referring to <FIG>, when the forcible open blocker <NUM> is pushed by the protruding portion <NUM> of the link <NUM> and thereby moves in the direction ① shown in <FIG>, the slide door <NUM> does not engage with the forcible open blocker <NUM> contrary to the case of <FIG>, and is movable freely in the first or second direction perpendicular to the direction ①. Therefore, when the forcible open blocking operation of the forcible open blocker <NUM> is released as shown in <FIG>, the slide door <NUM> can be opened or closed in accordance with the movement of the link <NUM>.

<FIG> is an exploded perspective view showing arrangements <NUM> of a slide door <NUM> and a guide rail <NUM> for guiding a movement of the slide door according to certain embodiments. <FIG> is a plan view showing a structure of a guide rail <NUM> according to certain embodiments. <FIG> is a view showing a coupling structure <NUM> of a slide door <NUM>, a guide rail <NUM>, a forcible open blocker <NUM>, and a link <NUM> according to certain embodiments.

Referring to <FIG>, <FIG> and <FIG>, when the link <NUM> linearly moves, the slide door <NUM> moves to open or close along a path formed by at least one groove <NUM> and <NUM> in the guide rail <NUM>.

For example, the guide rail <NUM> may be disposed under the slide door <NUM>. The slide door <NUM> may include protrusions <NUM> and <NUM> respectively corresponding to the grooves <NUM> and <NUM> of the guide rail <NUM>. The protrusions <NUM> and <NUM> may slide along the grooves <NUM> and <NUM> of the guide rail <NUM>.

The slide door <NUM> may be physically connected to the link <NUM>. For example, the slide door <NUM> may include, at one end thereof, a protruding portion <NUM> for coupling with the link <NUM>. The protruding portion <NUM> of the slide door <NUM> may be disposed to engage with a ring-like portion of the link <NUM>.

Although <FIG> shows that the guide rail <NUM> disposed under the slide door <NUM>, this is provided as an example only. Alternatively, the guide rail <NUM> may be disposed above the slide door <NUM>, or the guide rails <NUM> may be disposed above and under the slide door <NUM>, respectively.

When opened or closed in accordance with the driving operation of the driving actuator, the slide door <NUM> moves at least partially in the movement direction of the link, and at least partially in the direction perpendicular to the movement direction of the link. For example, in order to guide the slide door <NUM> in moving at least partially in the inward direction of the electronic device <NUM> when the slide door <NUM> is opened, the guide rail <NUM> may include the grooves <NUM> and <NUM> as shown in <FIG> and <FIG>.

Because the slide door <NUM> is opened while moving inwardly within at least in part into the electronic device <NUM> and sliding laterally in the electronic device <NUM>, the electronic device <NUM> may be formed to be slimmer overall.

Referring to <FIG>, the ring-like portion of the link <NUM> (as shown in <FIG>) is provided as an example , and it is understood that any other modification of the ring-like portion may be used, if it can be engaged with the coupling portion <NUM> of the slide door <NUM>.

According to certain embodiments, the electronic device <NUM> includes the forcible open block <NUM> that blocks the opening of the slide door <NUM> when the opening <NUM> is closed by the slide door <NUM>, and moves to release the blockage in accordance with the movement of the link <NUM>.

According to certain embodiments, the electronic device <NUM> may operate the driving actuator to open the slide door <NUM> that encloses the opening <NUM>. The link <NUM> moves linearly in accordance with the driving operation of the driving actuator, and thereby open the slide door <NUM> via engagement with the link <NUM>.

When the driving actuator is operated to open the slide door <NUM>, the protruding portion <NUM> of the link <NUM> pushes the forcible open blocker <NUM> in accordance with a first movement of the link <NUM> produced by the driving operation of the driving actuator. As a result, the blockage provided by the forcible open blocker <NUM> is released.

In addition, based on the first movement and the subsequent second movement of the link <NUM> produced by the driving operation of the driving actuator, the slide door <NUM> may slide along the grooves provided in the guide rail <NUM>.

According to certain embodiments, when it is determined that a predetermined condition for closing the opening <NUM> is satisfied, the electronic device <NUM> may automatically close the slide door <NUM> to close the opening <NUM>. A number of examples of the predetermined condition are provided below.

For example, an example condition may include detecting a lapse of a predetermined time after the slide door <NUM> is opened, after which the electronic device <NUM> may close the slide door <NUM>.

Another example condition may include reception of an external input signal through the input module or the communication module that meets a predetermined authentication condition, after which the electronic device <NUM> may close the slide door <NUM>.

Another example condition includes determining, based on a power supply control signal, that the system power supply to the electronic device <NUM> is stopped, after which the electronic device <NUM> may close the slide door <NUM>.

As such, if it is determined that a condition for closing the opening <NUM> is satisfied, the electronic device <NUM> may operate the driving actuator to move the link <NUM> in the second direction opposite to the first direction where the link <NUM> moves for opening the opening <NUM>.

The slide door <NUM> moves to a position of closing the opening <NUM> in accordance with the movement of the link <NUM> in the second direction.

According to certain embodiments, the forcible open blocker <NUM> is transitioned to a blocking position by the movement of the link <NUM> in the second direction and the elastic force of the elastic member of the forcible open blocker <NUM>. Therefore, when the opening <NUM> of the electronic device <NUM> is closed, the slide door <NUM> may disallow any opening, and permit opening by the driving operation of the driving actuator.

According to certain embodiments, the electronic device <NUM> may open or close the slide door <NUM> to open or close the opening <NUM> when a predetermined condition is satisfied. In particular, based on the linear movement of the link <NUM> in accordance with the driving operation of the driving actuator, the electronic device <NUM> can open the opening <NUM> easily and automatically by releasing the forcible open blocking of the forcible open blocker <NUM> and moving the slide door <NUM> without requiring any further operation. In addition, based on the linear movement of the link <NUM> in accordance with the driving operation of the driving actuator, the electronic device <NUM> can close the opening <NUM> by moving the slide door <NUM> and also enable the forcible open blocker <NUM> to effectively block the forcible open of the slide door <NUM>. This is advantageous to enhancing the security of components that can be inserted into the opening <NUM>.

The electronic device according to certain embodiments may be one of various types of electronic devices. According to embodiments of the disclosure, the electronic devices are not limited to those described above.

As used herein, each of such phrases as "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases.
