The present invention relates to a side key included in a portable terminal capable of switching between a volume control function and a scrolling function.

1 is a block diagram illustrating a portable terminal including a side key according to an embodiment of the present invention.

Referring to FIG. 1, the side key 100 according to an embodiment of the present invention may be provided in the portable terminal 200. The front side of the side key 100 may be disposed to face the side of the portable terminal 200.

The side key 100 may be embedded in the portable terminal 200 and a portion of the switch housing 50 included in the side key 100 may be exposed on the outer surface of the portable terminal 200. [

The portable terminal 200 may be a mobile phone, a mobile phone, a smart phone, a mobile communication terminal, a personal digital assistant (PDA), a tablet, a notebook, and the like, but is not limited thereto. The side key 100 according to one embodiment of the present invention is a smart key that has a volume control function and displays contents or the like on a display screen to perform functions such as scrolling, watch, navigation, and the like.

2 is a schematic perspective view of a side key according to one embodiment of the present application;

2, the side key 100 according to one embodiment of the present invention mainly includes a main body 10, a pair of push switches 21 and 22, a pair of micro switches 31 and 32, (40) and a switch housing (50).

A pair of push switches 21 and 22 may be disposed on the front surface of the main body 10 at mutually spaced intervals. The pair of push switches 21 and 22 may be disposed at both ends of the main body 100. The push switches 21 and 22 may be switches that generate a click event each time the push switch 21 or 22 is pressed.

The pair of push switches 21 and 22 perform any one of the volume control function of the portable terminal 200 and the scrolling function of the contents provided by the portable terminal 200, 31, and 32 may perform other functions of the volume control function and the scrolling function. For example, the pair of push switches 21 and 22 perform a volume control function, and the pair of micro switches 31 and 32 may provide a scrolling function. A more detailed description follows.

The pair of push switches 21 and 22 may be a switch provided to adjust the audio volume provided by the portable terminal 200. The pair of push switches 21 and 22 may include a first push switch 21 and a second push switch 22. For example, the first push switch 21 may be provided to reduce the audio volume, and the second push switch 22 may be provided to increase the audio volume, or vice versa.

A pair of micro switches (31, 32) can be disposed between the pair of push switches (21, 22) at mutually spaced intervals. The pair of microswitches 31 and 32 may be built in the main body 10. The microswitches 31 and 32 are small switches that perform precise operation, and can detect a slight pressing input.

The pair of micro switches 31 and 32 may be a switch provided to scrolle contents or the like provided by the portable terminal 200. The pair of microswitches 31 and 32 may include a first microswitch 31 and a second microswitch 32. For example, the first micro switch 31 may be provided for scrolling contents downward, and the second micro switch 32 may be provided for scrolling contents upward, or vice versa.

The pair of push switches 21 and 22 intuitively provide a feeling of functionally stepping and the pair of micro switches 31 and 32 functionally provide a smooth feeling (for example, Feel like scrolling) can be intuitively provided

A push lock switch 40 may be disposed between the pair of microswitches 31, 32. The push-lock switch 40 is a switch that is locked when pressed. The push-lock switch 40 is maintained in the OFF state when not pressed, and can be held in the ON state when pressed. The OFF state of the push lock switch 40 may be a state in which the pressed state is released, and the ON state may be a push lock state or a state in which the pressed state is maintained.

Depending on whether the push lock switch 40 is in the pressed lock state or in the depressed state, it can be determined whether the side key 100 is the volume adjusting mode or the scrolling mode.

When the push lock switch 40 is pressed and locked, the function corresponding to the input by the pair of micro switches 31 and 32 can be deactivated. When the push lock switch 40 is pressed and locked, the function corresponding to the input by the first micro switch 31 (i.e., the downward scrolling function) That is, an upward scrolling function) can be deactivated. This can be more easily understood with reference to FIGS.

FIG. 3 is a diagram illustrating ON / OFF states of a push lock switch in a side key according to an embodiment of the present invention, and FIG. 4 is a diagram illustrating a change in a push amount with respect to a switch housing in a side key according to an embodiment of the present invention .

3 (a) shows a state in which the push lock switch 40 is depressed, and Fig. 3 (b) shows a state in which the push lock switch 40 is pressed and locked.

Fig. 4A is a state when the pushing operation is not applied to the switch housing 50, and corresponds to a state in which the push-lock switch 40 is released (Fig. 3 (a)). 4 (b) corresponds to a state where the pushing operation is applied to the switch housing 50 by the first pressing amount, and corresponds to a state in which the push-lock switch 40 is pressed and locked (Fig. 3 (b)). 4 (c) shows a state when the pushing operation is applied to the switch housing 50 by the second pushing amount in the state as shown in Fig. 4 (b). 4, only the portion of the pair of push switches 21 and 22 where the second push switch 22 is located will be described for the convenience of explanation. The same applies. At this time, the first pushing amount means the pushing amount corresponding to the first distance d1, and the second pushing amount means the pushing amount corresponding to the second distance d2.

3 (a) and 4 (a), in the state in which the push-lock switch 40 is depressed, both ends in the longitudinal direction of the switch housing 50 are connected to a pair of push switches 21 and 22 (For example, the first distance d1) from the front side of the first lens group.

The lower surface of the switch housing 50 and the lower surface of the pair of push switches 21 and 22 are positioned so that both ends of the switch housing 50 are spaced apart from the pair of push switches 21 and 22 by a predetermined distance (first distance d1) A pair of flat springs 61 and 62 may be provided between the front surfaces of the first and second plates 31 and 32. At this time, the distance between the upper surfaces of the pair of micro switches 31 and 32 and the leaf springs 61 and 62 contacting the lower surface of the switch housing 50 in the state in which the push lock switch 40 is released, 3 distance (d3).

A pair of leaf springs (61, 62) can support the lower surface of the switch housing (50). The pair of leaf springs 61 and 62 are connected to the first leaf spring 61 positioned on the front surface of the first micro switch 31 and the second leaf spring 62 positioned on the front surface of the second micro switch 32 ).

When the leaf springs 61 and 62 are bent in the state as shown in Fig. 3 (a) and in the state shown in Fig. 3 (b) by the pressing of the switch housing 50, (or can be restored) enough to return to the same state as in (a). The leaf springs (61, 62) can provide elasticity to the input by at least one of the pair of microswitches (31, 32).

In other words, when the end of the leaf springs 61 and 62 is changed from the third distance d3 to the fourth distance d4 or the fifth distance d5 by the depression of the switch housing 50, The elastic members 61 and 62 may have elasticity enough to return to the state of the third distance d3.

3, the leaf springs 61 and 62 may be formed so as to be inclined in the direction of the pair of push switches 21 and 22 at the center portions of the pair of micro switches 31 and 32. The leaf springs 61 and 62 may be iron leaf springs.

The switch housing 50 is a structure that covers the upper side of the main body 10 so as to be able to press the pair of push switches 21 and 22, the pair of micro switches 31 and 32 and the push lock switch 40 have. The switch housing 50 can be positioned so that both ends in the longitudinal direction correspond to the pair of push switches 21 and 22. [

The function corresponding to the pair of micro switches 31 and 32 (for example, the scrolling function) may be in the activated state (i.e., the scrolling mode state) in the state where the push lock switch 40 is depressed.

3 (a), when a pressing operation of a distance smaller than the first distance d1 occurs in the area B of the switch housing 50 corresponding to the second micro switch 32, the upward scrolling function Can be performed. It is preferable that the upward scrolling function is performed through a pressing operation corresponding to the distance within the first distance d1 (i.e., an operation corresponding to the first pressing amount). This is because when the pushing operation corresponding to the distance exceeding the first distance d1 is made, not only the input by the second micro switch 32 but also the input by the second push switch 22 can be performed together to be. Since the micro switch has a structure capable of inputting only with a slight pressing similar to a touch method, the upward scrolling function can be performed with a push amount much smaller than the first distance d1.

3 (a), when a pushing operation with a smaller distance than the first distance d1 occurs in the region B of the switch housing 50 corresponding to the first micro switch 31, The scrolling function can be performed. This can be understood by the same principle as the upward scrolling function described above, and duplicated description will be omitted. According to an embodiment of the present invention, the pressing operation is performed only for the B region in order to perform the scrolling function. However, the present invention is not limited to this, and it is possible to correspond to the distance within the first distance d1 in the A region A scrolling function can be performed even when a pressing operation is performed.

When the switch housing 50 is changed from the state shown in Fig. 4 (a) to the state shown in Fig. 4 (b) (i.e., the first distance d1 to the switch housing 50) The push lock switch 50 may not be pressed by the elastic members 51 and 52 to be described later. However, in some cases, a slight depression may occur in the push-lock switch 50, and the depression may be a slight depression to the extent that the push-lock switch 40 is not in the depressed state.

3 (b) and 4 (b), when the push lock switch 40 is pressed and locked, both ends of the switch housing 50 in the longitudinal direction are connected to a pair of push switches 21 and 22 ). &Lt; / RTI >

The leaf springs 61 and 62 are pressed against the upper surface of the pair of micro switches 31 and 32 and the lower surface of the switch housing 50 while the leaf spring 61, 62 can be maintained at the fourth distance d4. At this time, the fourth distance d4 may be a distance obtained by subtracting the push-lock switch 40 from the third distance d3.

In a state in which the push lock switch 40 is pressed and locked, a function corresponding to the pair of micro switches 31 and 32 (for example, a scrolling function) may be in an inactivated state. Therefore, in a state where the push lock switch 40 is pressed and locked (a state as shown in FIG. 4 (b)), a scrolling function is not performed when a small amount of depression is generated in the area B.

The pair of push switches 21 and 22 may be in the activated state while the push lock switch 40 is pressed and locked.

When the pressing corresponding to the second pressing amount occurs in the area A in the state where the push lock switch 40 is pressed and locked, the function corresponding to the pair of push switches 21 and 22 can be performed. At this time, the second pushing amount may be a pushing amount corresponding to the second distance d2. When the second pushing amount is generated in the state shown in Fig. 4 (b), the state shown in Fig. 4 (c) can be obtained.

3 (b), when the second pushing amount is generated in the area A of the switch housing 50 corresponding to the second push switch 22, the audio volume can be increased. Similarly, when the second pushing amount is generated in the area A of the switch housing 50 corresponding to the first push switch 22, the audio volume can be reduced. In this case, according to an embodiment of the present invention, the pressing operation is performed only for the area A in order to perform the audio volume adjusting function. However, the present invention is not limited to this, and the pressing operation corresponding to the second pressing amount in the area B The audio volume adjustment function can be performed even when an operation occurs.

The pair of push switches 21 and 22 may not be inputted with a position and a pressing amount at which an input (for example, an input for a scrolling function) to the pair of micro switches 31 and 32 is made have. In the case of the pair of push switches 21 and 22, when the input of the first pushing amount (the pushing amount corresponding to the distance within the first distance d1) is applied in the state as shown in FIG. 3A, I can not.

On the other hand, in a state in which the push lock switch 40 is pressed and locked, since the pair of micro switches 31 and 32 are input even by a fine pressing operation, the input to the pair of push switches 21 and 22 The input can be performed also by the position and the amount of pressing. For example, when an input (e.g., an input to a volume control function) is made to a pair of push switches 21, 22 while the push lock switch 40 is pressed and locked, The switches 31 and 32 may also be input by pressing. However, since the function corresponding to the input by the pair of microswitches 31 and 32 is inactivated in a state where the push-lock switch 40 is in a push-lock state, (E.g., a scrolling function) corresponding to the input to the pair of push switches 21 and 22 is not performed, and only a function corresponding to the input to the pair of push switches 21 and 22 have. That is, in the present invention having a physical input system using a micro switch and a push switch, an effective malfunction prevention system can be constructed by providing the push lock switch 40.

3 (b), the switch housing 50 includes an elastic deformation portion 51 (see FIG. 3) formed in a corresponding portion between the push-lock switch 40 and one of the pair of push switches 21 and 22 , 52, 53, 54).

The elastic deformation portions 51, 52, 53 and 54 are formed in the switch housing 50 such that the elastic members 51, 52, 53 and 54 are formed at portions corresponding to the positions between the push lock switch 40 and one of the pair of micro switches 31, (51, 52).

The elastic deforming portions 51, 52, 53 and 54 are provided with cushion members 53 and 54 formed to buffer the pressing operation of one of the pair of push switches 21 and 22 in the switch housing 50, . &Lt; / RTI >

In the switch housing 50, the elastic deformation portions 51, 52, 53 and 54 are formed of a soft material, and the remaining portions of the switch housing 50 excluding the elastic deformation portions 51, 52, 53, As shown in FIG.

The elastic deformation portions 51, 52, 53 and 54 are formed by a pushing operation in which a pushing lock or depressing operation is performed on the push-lock switch 40 and a pushing operation in which an input to one of the pair of push switches 21, And the pressing operation can be performed independently of each other.

(Or an external force) applied to the C-region to perform a pressing operation on the push-lock switch 40, a pair of push switches 21 and 22 and a pair of microswitches 31 and 32 may not be pressed by the elastic members 51 and 52. However, in some cases, when a push operation is performed on the push lock switch 40, a slight degree of depression may occur in the pair of micro switches 31 and 32, and a pair of push switches 21 and 22 , The pressing operation may be buffered by the cushion members 53 and 54, so that the pressing may not occur.

Therefore, when the push lock switch 40 is changed from the depressed state as shown in Fig. 3 (a) to the depressed locked state as shown in Fig. 3 (b), the pair of micro- And the pair of push switches 21 and 22 may not be pressed by the cushion members 53 and 54. In this case,

The side key 100 according to one embodiment of the present invention may include a pair of dome members (not shown) to provide a click feeling in a pressing operation corresponding to the pair of push switches 21 and 22. [ The dome member (not shown) may be provided so as to surround the pair of push switches 21 and 22.

The pair of push switches 21 and 22 are connected to a function corresponding to the pair of push switches 21 and 22 and a function corresponding to the pair of push switches 21 and 22 when a pushing operation of more than a predetermined time (for example, three seconds) (31, 32) can be mutually switched.

When the pushing operation of the pair of push switches 21 and 22 occurs for a predetermined time or longer in a state where the push lock switch 40 is released (that is, a state as shown in Fig. 3 (a) and a scrolling mode state) The current operation mode (scrolling mode) can be automatically switched to the volume control mode. At this time, when switching from the scrolling mode to the volume control mode, the push lock switch 40 can be automatically changed from the pressed state to the pressed lock state.

On the other hand, when the push-lock switch 40 is depressed and locked (i.e., in a state as shown in Fig. 3 (b) and in the volume control mode), the pushing operation of the pair of push switches 21, When this occurs, the current operation mode (volume control mode) can be automatically switched to the scrolling mode. At this time, when the mode is switched from the volume control mode to the scrolling mode, the push lock switch 40 can be automatically changed from the pressed lock state to the depressed state.

The side key 100 according to one embodiment of the present invention can perform a volume control function and a scrolling function through one side key 100. [ The side key 100 can more clearly distinguish the inputs to the two functions through the push lock switch 40 and the elastic deformation parts 51, 52, 53 and 54 when the volume control function and the scrolling function are switched to each other, Malfunction can be reduced.

It will be understood by those of ordinary skill in the art that the foregoing description of the embodiments is for illustrative purposes and that those skilled in the art can easily modify the invention without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.

The scope of the present invention is defined by the appended claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
