The present invention relates to a touch input device, and more particularly, to a touch input device capable of extending a recognition area of a touch as well as preventing foreign substances from entering the touch input device.

The touch input device uses touch recognition technology such as resistive overlay, capacitive overlay, surface acoustic wave, and infrared ray. Conventional touch recognition technology is limited to 2D touch interaction because it recognizes touch coordinates in the plane, i.e., X-axis coordinate and Y-axis coordinate.

In order to overcome the limitation of the conventional two-dimensional touch interaction, a force-based touch recognition technology (three-dimensional touch interaction) for recognizing a touch force with a touch sensor using a force sensor has been proposed.

However, in the conventional touch input device, the touch can be recognized only in the inner area of the virtual frame connected by the plurality of force sensors attached to the bottom edge of the touch panel, and the touch in the area outside the virtual frame Can not be recognized. That is, when the force sensor is attached to the edge of the touch panel, the recognition area of the touch is narrowed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. For the sake of convenience, the size, line thickness, and the like of the components shown in the drawings referenced in the description of the present invention may be exaggerated somewhat. The terms used in the description of the present invention are defined in consideration of the functions of the present invention, and thus may be changed depending on the user, the intention of the operator, customs, and the like. Therefore, the definition of this term should be based on the contents of this specification as a whole.

Referring to FIG. 1, various embodiments of the present invention include a housing 20 in which a touch plate 10 and a touch plate 10 are installed.

The touch plate 10 may have a first surface 11 facing the first direction X1 and a second surface 12 facing the second direction X2 opposite to the first direction X1.

The first surface 11 corresponds to the top surface to which the touch is applied and the second surface 12 corresponds to the bottom surface opposite to the first surface 11. [ Accordingly, the second surface 12 can receive a force in the first direction X1 or the second direction X2 by the touch applied to the first surface 11.

At least one sensor 41 for recognizing a touch may be connected to the second surface 12 of the touch plate 10 via an elastic body 30.

The elastic body 30 is connected to the second surface 12 of the touch plate 10 and the elastic body 30 is moved in the first direction X1 by a touch applied to the first surface 11 of the touch plate 10. [ And the second direction (X2).

The housing 20 can be configured to allow the touch plate 10 to move in the first direction X1 and / or the second direction X2.

A touch plate 10 may be disposed on the upper portion of the housing 20 and a second surface 12 of the touch plate 10 may be disposed to face the housing 20.

According to the embodiment of FIG. 1, the housing 20 may have a bottom portion 21 located opposite the touch plate 10 and a side wall 22 formed at the edge of the bottom portion 21.

An opening 25 is formed in the upper portion of the housing 20 and an extension portion 23 extends inward at a predetermined length at the edge of the opening 25.

The touch plate 10 may be installed adjacent to the opening 25 of the housing 20 and the edge of the touch plate 10 may be located below the extending portion 23. [

Particularly, an elastic member 70 is interposed between the edge of the touch plate 10 and the extension portion 23 of the housing 20, and the elastic member 70 can be made of an elastic material having a sealing property such as rubber .

As described above, according to the present invention, movement of the touch plate 10 in the first direction or the second direction can be allowed by the elastic member 70. Since the elastic member 70 has a sealing property, external foreign matter can be prevented from flowing into the housing 20 when the touch plate 10 is flowing.

A concrete installation structure of the elastic body 30 will be described with reference to FIG.

2, the protrusion 14 is formed on the second surface 12 of the touch plate 10 so as to protrude toward the second direction X2, and the bottom portion 21 of the housing 20 The support body 35 may be provided so as to protrude toward the first direction X1.

The protrusions 14 and the support bodies 35 may be spaced from each other in a direction orthogonal to the first direction X1 and the second direction X2 (i.e., the horizontal direction in Fig. 1). One end 31 of the elastic body 30 is connected to the second surface 12 of the touch plate 10 by being fixed to the projection 14 with an adhesive or the like and the other end 32 of the elastic body 30 is connected to the support 35 To the first surface 21 of the base plate 20. [0050] In order to maintain the horizontality of the elastic body 30, the lower end of the protrusion 14 has a length corresponding to one end 31 of the elastic body 30 And the upper end of the support body 35 can protrude to a length corresponding to the other end 32 of the elastic body 30. [

When the touch is applied to one side of the first surface 11 of the touch plate 10, the elastic body 30 is moved in the first direction X1 and the second direction X2 with respect to the other end 32, And the direction X2, the elastic body 30 can perform the behavior of a cantilever.

A force due to the touch can be smoothly transmitted to the one end 31 of the elastic body 30 through the protrusion 14 protruded from the second surface 12 of the touch plate 10, The elastic body 30 can be spaced apart from the second surface 12 of the touch plate 10 by a predetermined distance so that the deformation of the elastic body 30 by the touch applied to the touch plate 10 can be stabilized .

3 to 8 are views showing a mounting structure of the elastic body 30 according to another embodiment of FIG.

3, the connection bracket 50 is fixed to one end 31 of the elastic body 30 with an adhesive or the like and the connection bracket 50 has a structure having a U-shaped groove 51 And one end 31 of the elastic body 30 can be fitted into the groove 51 of the connection bracket 50 and coupled. The upper surface of the connection bracket 50 can be fixed to the bottom surface of the projection 14 with an adhesive or the like.

Therefore, the force of the touch applied to the touch plate 10 is more smoothly transmitted to the one end 31 of the elastic body 30 through the connection bracket 50, so that the deformation of the elastic body 30 can be stably performed.

4, the connecting bracket 50 has one or more pressing projections 52 for pressing one end 31 of the elastic body 30 and the pressing projections 52 are engaged with the grooves of the connecting bracket 50 51 so that one end 31 of the elastic body 30 can be pressed more firmly.

5, the connection bracket 50 includes an insertion portion 53 passing through one end 31 of the elastic body 30, an upper elastic pressing portion 54 provided at the upper end of the insertion portion 53, And a lower pressing portion 55 provided at the lower end of the inserting portion 53. A through hole 31a is formed at one end 31 of the elastic body 30 and an insertion portion 53 of the connection bracket 50 can be inserted into the insertion hole 31a of the elastic body 30. [ Thus, the connection bracket 50 can be firmly coupled by pressing one end 31 of the elastic body 30 upward and downward.

According to the embodiment of Fig. 6, the connection bracket 50 may be composed of a fastening screw having a head portion 56 and a threaded portion 57. A fastening hole 31b may be formed at one end 31 of the elastic body 30 and a threaded portion 57 of the connection bracket 50 may be screwed to the fastening hole 31b of the elastic body 30 .

7, a wedge-shaped wedge portion 58 protrudes at one side of the protrusion 14, and a wedge groove 31c may be formed at one end 31 of the elastic body 30. As shown in Fig. Thus, the wedge portion 58 of the projection 14 can be wedged into the wedge groove 31c of the elastic body 30.

8, a horizontal portion 69a extends horizontally at one side of the protrusion 14, and a coupling portion 69b can protrude in a stepped manner at the horizontal portion 69a, and the elastic body 30 The coupling groove 31d may be formed at one end 31 of the coupling groove 31d. Thus, the engaging portion 69b of the projection 14 can be fitted into the engaging groove 31d of the elastic body 30.

The sensor 41 is attached to the elastic body 30 and the sensor 41 is configured to measure the force due to the touch applied to the first surface 11 of the touch plate 10 in response to deformation of the elastic body 30 . In other words, the elastic body 30 can be configured to transmit a force by the touch to the sensor 41 side.

Thus, the sensor 41 senses that the elastic body 30 is deformed by the touch applied to the touch plate 10, and by measuring the force, the position coordinates of the touch or the strength of the touch can be recognized.

According to one embodiment, the sensor 41 is a strain gauge that measures the force while bending in response to deformation of the elastic body 30 in the first direction X1 or the second direction X2 Lt; / RTI >

In particular, as shown in FIG. 1, one or more sensors 41 are disposed inwardly spaced from the edges of the touch plate 10 (see S1 and S2 in FIG. 1) It is possible to precisely measure the deformation of the elastic body 30 in the first direction X1 or the second direction X2 along the entire surface of the first surface 11 of the touch plate 10, So that the touch recognition area can be greatly expanded.

As illustrated in Fig. 1, two sensors 41 are disposed adjacent to the edge of the touch plate 10 in a state in which they are spaced inward from the edge of the touch plate 10 (see S1 and S2 in Fig. 1) When a touch of a constant external force F is applied to the one point in the second direction X2, the touch plate 10 can perform the lever action with the point A as a fulcrum, The first reaction force F A may be generated by the first reaction force X1 and the second reaction force F B may be generated at the point B in the second direction X3. Accordingly, the sensor 41 located at the point A can output a signal to be pressed in the first direction X1, and the sensor 41 positioned at the point B outputs a signal that is stretched in the second direction X2 The sensors 41 can measure the forces F A and F B generated at each point and thus the force measured by the sensors 41 and the distance between the sensors 41 can be calculated from the equilibrium equation of force and moment The coordinates of the touch or the intensity of the touch can be recognized.

Compared to the prior art, a force sensor is disposed at the edge of the touch panel, and therefore, the force sensor outputs only a signal to be pressed in the second direction, The recognition of the touch may be limited by processing the signal as a noise signal. In contrast, according to the present invention, since the sensor 41 is disposed so as to be spaced inwardly from the edge of the touch plate 10, not only the signal pressed in the second direction X2 but also the signal that is pulled in the first direction X1 So that the touch recognition can be performed more accurately and the recognition area of the touch can be expanded.

9 shows a structure in which a plurality of sensors 41a, 41b, 41c, and 41d are disposed at positions spaced inwardly from the edge of the touch plate 10. In FIG. 45b, 45c, 45d, 45e, 45f, 45h (45a, 45b, 45c, 45d) by a plurality of imaginary lines 43a, 43b, 43c, 43d connecting the plurality of sensors 41a, 41b, 41c, , 45i can be partitioned.

The plurality of sensors 41a, 41b, 41c, and 41d may be referred to as a first sensor 41a, a second sensor 41b, a third sensor 41c, and a fourth sensor 41d. Also, the signal pressed in the second direction is referred to as the (+) signal, and the signal that is stretched in the first direction may be referred to as the negative signal.

The first sensor 41a closest to the first touch region 45a can output a strong positive signal when a touch touched in the second direction is applied to the first touch region 45a, The fourth sensor 41d located diagonally opposite the region 45a can output a strong (-) signal. The second sensor 41b and the third sensor 41c are hardly influenced by the touch on the first touch region 45a, so that they can output no signal.

The first sensor 41a and the second sensor 41b adjacent to the second touch region 45a output a weak (+) signal when a touch to be pressed in the second direction is applied to the second touch region 45b And the third sensor 41c and the fourth sensor 41d located on the opposite side of the second touch region 45c can output a weak (-) signal.

The second sensor 41b closest to the third touch region 45c can output a strong (+) signal when a touch to be pressed in the second direction is applied to the third touch region 45c, The fourth sensor 41c located diagonally opposite the region 45c can output a strong (-) signal. Since the first sensor 41a and the fourth sensor 41d are hardly influenced by the touch on the third touch region 45c, they may not output any signal.

The first sensor 41a and the third sensor 41c adjacent to the fourth touch region 45d output a weak (+) signal when a touch touched in the second direction is applied to the fourth touch region 45d And the second sensor 41b and the fourth sensor 41d located opposite the fourth touch region 45d can output a weak (-) signal.

When a touch touched to the fifth touch region 45e in the second direction is applied, the plurality of sensors 41a, 41b, 41c, and 41d can output a (+) signal.

The second sensor 41b and the fourth sensor 41d adjacent to the sixth touch region 45f output a weak (+) signal when a touch to the sixth touch region 45f is pressed in the second direction And the first sensor 41a and the third sensor 41c can output a weak (-) signal on the opposite side of the sixth touch region 45f.

The third sensor 41c closest to the seventh touch region 45g can output a strong (+) signal when a touch to be pressed in the second direction is applied to the seventh touch region 45g, The second sensor 41b located diagonally opposite the region 45g may output a strong (-) signal. Since the first sensor 41a and the fourth sensor 41d are hardly influenced by the touch on the seventh touch region 45g, they may not output any signal.

The third sensor 41c and the fourth sensor 41d adjacent to the eighth touch region 45h output a weak (+) signal when a touch to be pressed in the second direction is applied to the eighth touch region 45h And the first sensor 41a and the second sensor 41b located opposite the eighth touch region 45h can output a weak (-) signal.

The fourth sensor 41d closest to the ninth touch region 45i can output a strong (+) signal, and when the ninth touch region 45i is touched in the second direction, The first sensor 41a located diagonally opposite the region 45i can output a strong (-) signal. Since the second sensor 41b and the third sensor 41c are hardly influenced by touching the ninth touch region 45i, they may not output any signal.
