Hereinafter, a detailed structure of a button assembly included in a mobile terminal according to an embodiment of the present invention will be described with reference to FIGS. 4 to 6.

For convenience of description, it will be assumed that the first operation unit 131 provided at the lower end of the front surface among the operation units 131, 132, and 133 provided in the mobile terminal body, which will be described below, is made of a button type. In addition, the first operation unit 131 formed of a button method may represent the 'button unit 131' described below. However, the button unit 131 is not limited to the first manipulation unit 131, and may include all of the second or third manipulation units.

In addition, Figure 5 is a perspective view of the support member 200 related to the present embodiment, Figure 6 is a cross-sectional view showing the appearance of the support protrusion 210 included in the support member 200 according to the present embodiment It is.

As shown in FIG. 4, a mobile terminal according to an embodiment of the present invention includes a housing 101, 101 ′, 102, an inner frame (not shown), a button part 131, and a support member 200. . At this time, the support member 200 includes a pair of support protrusions 210 protruding from the support member 200.

As described above, the housing forms the exterior of the mobile terminal body and may include cases 101 and 102 and a window glass 101 '. The cases 101 and 102 may be further divided into a front case 101 and a rear case 102. As shown in FIG. 4, the window glass 101 ′ may be inserted into the front case 101, and ribs 1011 may be formed below the front case 101 to form a rear surface of the bottom of the window glass 101 ′. It can be located at

An inner frame (not shown) is mounted inside the housing. For example, the inner frame may be provided in a space between the front case 101 and the rear case 102, and may support the display module 151 ′ and protect the display module 151 ′ from external impact. . In FIG. 4, although the rib of the front case 101 is illustrated below the display module 151 ′, a portion of the inner frame may be exposed instead of the rib 1011 of the front case 101 at the position. In this case, an inner frame may be located at the rear of the bottom of the window glass 101 '.

As shown in FIGS. 4 and 6, the button portion 131 is configured such that an upper surface thereof is exposed to the outside of the housing and, when pressed, is movable to the inside of the housing. For example, as illustrated in FIG. 4, the button unit 131 may be provided through the window glass 101 ′ forming the front surface of the mobile terminal body. As another example, the button unit 131 may be provided through the front case 101 or the rear case 102. According to the present embodiment, the button portion 131 may have a long shape in which the longitudinal end is longer than the transverse end as shown in FIG. 4. In this case, the longitudinal direction of the button portion 131 may be determined in parallel with the longitudinal end portion.

The support member 200 elastically supports the bottom surface of the button part 131 so that the button part 131 returns to its original position when the pressure of the button part 131 is released. That is, the support member 200 is made of an elastic material to support the bottom surface of the button portion 131 and to press the button portion 131 when the button portion 131 is pressed to move inside the housing. It can be elastically deformed. When the pressing of the button portion 131 is released, the deformed support member 200 may return the button portion 131 to its original position while being returned to its original state by elasticity. The support member 200 may be made of a plastic having elasticity or may be made of a metal having elasticity.

At this time, both longitudinal ends of the supporting member 200 are fixed to the housing or the inner frame. To this end, as shown in Figures 4 and 5, the support member 200 may be formed in a long shape, the longitudinal end is longer than the transverse end, the longitudinal direction may be determined in parallel with the longitudinal end. As both ends in the longitudinal direction are fixed to the housing or the inner frame, the shape of the portion between the two longitudinal ends of the support member 200 may be deformed by a force for pressing the button portion 131. In addition, since the positions of both ends of the support member 200 are fixed, the position of the button part 131 supported by the support member 200 may also be fixed.

Both longitudinal ends of the support member 200 may be fixed to the ribs 1011 of the front case, as shown in FIG. 4. If a part of the inner frame is exposed on the rear surface of the button unit 131 instead of the rib 1011 of the front case, both ends of the support member 200 in the longitudinal direction may be fixed to the inner frame.

Meanwhile, as shown in FIG. 6, the mobile terminal of the present invention may further include a switch unit 300 and an actuator 400. The switch unit 300 is disposed inside the support member 200 to generate a control signal when pressed. The actuator 400 may be formed to protrude from the other surface of the support member 200, and may press the switch unit 300 when the button unit 131 moves to the inside of the housing. As the support member 200 is deformed by a force for pressing the button 131, the actuator 400 protruding from the support member 200 may move to the inside of the housing, and may press the switch 300. Preferably, the switch unit 300 and the actuator 400 may be disposed on the center line of the button unit 131, respectively.

According to an embodiment, as shown in FIGS. 5 and 6, the support member 200 may include a base panel 220 and a pair of fixing supports 230.

The base panel 220 may be formed in a plate shape corresponding to the shape of the bottom surface of the button portion 131, and preferably may have a long shape in which the longitudinal end is longer than the transverse end. One surface of the base panel 220 may contact the bottom surface of the button unit 131. According to an embodiment, the length of the base panel 220 may be greater than the length of the button unit 131. In this case, as shown in FIG. 6, when the button portion 131 is positioned at the center of the base panel 220, the clearance portion 2201 is located outside the horizontal end of the button portion 131 of the base panel 220. This can be formed.

The pair of fixing supports 230 may extend from both ends in the longitudinal direction of the base panel 220, respectively, and protrude in the other surface direction of the base panel 220. That is, the fixing support 230 may protrude in the opposite direction of the button portion 131. The end of the fixing support 230 as described above may be fixed to the housing or the inner frame.

In this case, as shown in FIG. 6, a pair of fixing supports 230 may support the base panel 220 at both ends in the longitudinal direction of the base panel 220. The base panel 220 supports the button part 131, and when the button part 131 is pressed, the shape of the base panel 220 is deformed so that the button part 131 may move inside the housing. When the pressing of the button unit 131 is released, the shape of the panel 220 may be restored by elasticity of the material, and the button unit 131 may be returned to its original position.

5 and 6, a pair of support protrusions 210 are formed in the support member 200. The pair of support protrusions 210 protrude from the other surface of the support member 200. That is, the support protrusion 210 protrudes in the opposite direction of the button portion 131. For example, as shown in FIG. 5, when the support member 200 includes the base panel 220 and a pair of fixed supports 230, the support protrusion 210 is fixed from the base panel 220. It may protrude in the same direction as 230. As described above, when the actuator 400 is formed to protrude from the support member 200, the actuator 400 may be formed between the pair of support protrusions 210.

In addition, the pair of support protrusions 210 protrude between both longitudinal ends of the support member 200. At this time, the pair of support protrusions 210 may be formed near both ends in the longitudinal direction of the support member 200, respectively. For example, as shown in FIGS. 5 and 6, each of the support protrusions 210 may be formed just inside the fixing support 230. When the length of the base plate is greater than the length of the button portion 131 as in the above-described embodiment, the pair of support protrusions 210 are each outside the transverse end of the button portion 131 of the base panel 220, respectively. It may protrude from the other surface of the portion formed, that is, the margin portion 2201.

As shown in Figure 6, the ends of the pair of support protrusions 210 are in contact with any one of the housing and the inner frame, respectively. As shown in FIG. 4, when the rib 1011 is formed on the front case, the pair of support protrusions 210 may contact the front case 101. If a part of the inner frame is exposed on the back of the button unit 131 instead of the rib 1011 of the front case, the support protrusion 210 may contact the inner frame.

The member in contact with the end of the support protrusion 210 may be the same as or different from the member to which the support member 200 is fixed. For example, when the fixing support 230 of the support member 200 is fixed to the rib 1011 of the front case, the support protrusion 210 may also contact the rib 1011 of the front case. Alternatively, the fixing support 230 of the support member 200 is fixed to the front case 101, but the support protrusion 210 may contact the inner frame.

In this case, the ends of the pair of support protrusions 210 may slide outwards when the button portion 131 moves to the inside of the housing (see FIG. 9). That is, when the portion between the both ends of the longitudinal direction of the support member 200 is pressed by the force for pressing the button portion 131, the end of the support protrusion 210 formed near both ends of the longitudinal direction of the support member 200 is Sliding on the surface of the housing or the inner frame may be spread out of the housing or outside.

As the pair of support protrusions 210 unfold outward, the base panel 220 of the support member 200 may be deformed in the inner direction of the housing. As a result, although the support protrusion 210 maintains the equilibrium of the base panel 220 by supporting portions between both longitudinal ends of the support member 200, the button portion 131 is pressed when the button portion 131 is pressed. ) Can be allowed to move.

As the support protrusion 210 is formed in the support member 200 as in the present embodiment, it is possible to effectively support the portion between the both ends in the longitudinal direction of the support member 200. As a result, when one end of the button portion 131 is pressed, the phenomenon that only the end of the support member 200 supporting the bottom of the end may be prevented from being deformed.

As the phenomenon in which only the end of the support member 200 is deformed is prevented, even when the end of the button portion 131 is pressed, the base panel 220 of the support member 200 can be effectively maintained in equilibrium, When pressed to the end of the button portion 131, the button portion 131 and the support member 200 is inclined to prevent the phenomenon that the actuator 400 formed on the support member 200 is not effectively moved. As a result, even when the end portion of the button portion 131 is pressed, the actuator 400 formed on the support member 200 is moved to the inside of the housing, and as a result, the switch portion disposed on the center line of the button portion 131 ( 300 can be clicked stably.

According to one embodiment, as shown in Figure 6, the ends of the pair of support protrusions 210 may be formed on the outer side than both ends in the longitudinal direction of the button portion 131, respectively. That is, each support protrusion 210 and the contact b of the housing or the inner frame may be formed outside the transverse end a of the button portion 131.

As in the present embodiment, when the ends of the support protrusions 210 are located outside the transverse ends of the button portion 131, respectively, the ends of the support protrusions 210 more effectively slide when the button portion 131 is pressed. can do. As a result, the pair of support protrusions 210 can be more effectively spread out by the force of pressing the button portion 131, the click feeling of the button can be improved.

Hereinafter, a detailed structure of a button assembly included in a mobile terminal related to various other embodiments of the present invention will be described with reference to FIGS. 7 to 9.

As shown in FIG. 7, a chamfer may be formed at the inner edges of the ends of each of the pair of support protrusions 210 formed on the support member 200. That is, the inner edges of the pair of support protrusions 210 formed near both ends in the longitudinal direction of the support member 200 may be formed as inclined surfaces.

According to another embodiment, as shown in FIG. 8, the inner side surface of each end of the pair of support protrusions 210 formed on the support member 200 may be formed of an inclined surface 2101 ′. That is, the inclined surface extending from the bottom of the base panel 220 of the support member 200 to the end of the support protrusion 210 is extended to the chamfer portion 2101 formed at the inner edge of the end of each support protrusion 210 ( 2101 '). The inclined surface 2101 ′ may start at the bottom of the base panel 220 of the support member 200 and extend to the end of the support protrusion 210, and as shown in FIG. 8, the base of the support member 200. The closer to the bottom surface of the panel 220 may have an inclination inclined toward the inside of the support member 200.

As shown in FIG. 9, when the chamfer portion 2101 of FIG. 7 or the inclined surface 2101 ′ of FIG. 8 is formed at the inner edge of each support protrusion 210, the button portion 131 moves to the inside of the housing. An end of the visual support protrusion 210 may be slid outward more easily. 9, the operation in the case where the inclined surface 2101 ′ is formed on the inner surface of each support protrusion 210 is representatively shown. As shown in FIG. 9, when the chamfer portion 2101 or the inclined surface 2101 ′ is formed inside the end portion of the support protrusion 210, the support protrusion 210 is chamfered when the button portion 131 is pressed. It can slide using the fur part 2101 or the inclined surface 2101 '.

When the button portion 131 is pressed to slightly open the support protrusion 210, the pair of support protrusions 210 are further contacted while the chamfer portion 2101 or the inclined surface 2101 ′ contacts one of the housing and the inner frame. It can happen effectively. As a result, the support protrusion 210 can more effectively allow the movement of the button portion 131 when the button portion 131 is pressed, and as a result, the click feeling of the button portion 131 can be improved.

On the other hand, the button assembly installed in the housing of the electronic device according to an embodiment of the present invention is a button unit configured to be movable when pressed and the button unit to return the button unit to its original position when the pressing of the button unit is released It may include a support member for elastically supporting the bottom surface.

At this time, the support member is a pair of the base panel which one surface is in contact with the bottom surface of the button portion, extends from both ends in the longitudinal direction of the base panel protruding toward the other surface of the base panel, the position of the end is fixed to the housing It may include a pair of support protrusions projecting between the fixed support and the pair of fixed support from the other surface of the support member and the end contacting the housing. The housing may include not only a case forming an external appearance of the electronic device but also various frames for supporting components and the like in the case.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
