Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

1 is an exploded perspective view illustrating a schematic configuration of a case for an electronic device having a touch type display panel according to the present invention.

The electronic device used in the present invention mainly relates to a portable electronic device. For example, electronic devices, PDAs, UMPCs, PMPs, MP3 players, and e-book readers may be present. Such electronic devices may be touch-type display panels. It can be interpreted that it is provided with.

As can be seen from Figure 1, the case according to the present invention is composed of the upper case 100 and the lower case 200, the lower case 200 is a portion of the bottom (back or lower surface) and side of the electronic device The upper case 100 has a structure that surrounds a portion of a side of the electronic device and a portion around a plane (a surface portion with a display panel) of the electronic device.

The most apparent feature of the case according to the present invention is that the upper case 100 is a structure in which only the frame is left so that the center portion is largely drilled to correspond to the size of the display panel of the electronic device so that the display panel of the electronic device is exposed to the outside It can be said that has.

That is, the upper case 100 is similar to the frame structure of the frame so that the upper case 100 does not cover the touch type display panel of the electronic device, thereby ensuring a state in which the user can smoothly operate the display panel of the electronic device.

The upper case 100 according to the present invention serves to cover only the peripheral portion of the electronic device to ensure that the electronic device is not separated from the entire case while ensuring the operating state of the electronic device, sufficient coupling force to ensure a minimum contact area with the electronic device The lower case 200 may cover an overall impact protection function for the electronic device and a part of the lower surface and the side surface of the electronic device to perform a scratch prevention function for the corresponding electronic device part.

In addition, the case according to the present invention is characterized in that the upper case 100 and the lower case 200 are made of a heterogeneous material, that is, the upper case 100 is made of a plastic to metal series having a relatively solid state, The lower case 200 is made of rubber or silicone having flexible properties.

The upper case 100 and the lower case 200 made of such heterogeneous materials may not be easily coupled unless there is an electronic device therebetween.

In other words, when the upper case 100 is coupled to the lower case 200, there is no fixed state due to the flexibility of the lower case 200 when there is no medium capable of supporting a force such as an electronic device therebetween. Without the flow state, the coupling portion of the upper case 100 is not firmly coupled to the lower case 200.

That is, the case according to the present invention is made to ensure the coupling relationship on the premise that the electronic device as an essential coupling element, the reason is to save the excellent inherent characteristics of the lower case 200.

Since the lower case 200 plays a role of supporting the lower surface of the electronic device, the lower case 200 should emphasize the role of protecting the electronic device from external shocks, that is, it may have more elasticity and elasticity than a material such as plastic or leather. Due to the nature of the silicone to the rubber, the lower case 200 according to the present invention is able to faithfully perform a buffer role of the external impact. Furthermore, the lower case made of silicone or rubber not only has superior self-scratch prevention function compared to metal or plastic, but may also provide a stable grip state to the user.

Therefore, in the present invention, the silicone or rubber having such elasticity is used as the base material of the lower case 200, the upper case 100 is made of the same material, or the lower case 200 is made of the same material as leather, which will be described later. The upper case is made of a relatively rigid plastic or metal material, because the detailed components for it are impossible to function properly.

In addition, the upper case 100 serves to wrap around the periphery of the display panel of the electronic device. If the upper case 100 is made of a flexible silicone material, it is expected that a considerable inconvenience will be caused by inserting and coupling the electronic device to the upper case 100. To ensure the firmness of the 100 is to be configured to be coupled to the upper surface of the peripheral portion of the electronic device in a manner that covers the upper case 100 to the electronic device more intuitive and convenient.

In addition, the anti-viscosity layer 290 is coated / coated on a surface on which the electronic device is seated in the lower case 200. The anti-viscosity layer 290 is formed by coating / coating a material having a relatively low coefficient of friction (small), that is, an anti-viscosity agent, on the electronic device accommodating surface of the lower case 200, such as lubricating oil, It may be a liquid such as an oil, a gel or a solid with a smooth surface consisting of a thin film.

That is, when the electronic device is adhered to a specific lower case surface when the electronic device is accommodated in the lower case 200 by the self-viscosity of rubber or silicon, the electronic device may change its position when the upper case 100 is covered by the lower case 200 later. If not found and attached to the lower case 200, there is a fear that the electronic device may not serve as a connection medium of the upper / lower case.

Therefore, by applying the viscosity preventing layer to the inner surface of the lower case 200, that is, the contact surface of the electronic device to ensure the detailed fluidity of the electronic device to ensure precise coupling between the upper case 100 and the lower case 200 It not only helps to locate homes but also serves as a faithful linking medium. Of course, since the size of the lower case 200 is manufactured to correspond to the size of the electronic device does not cause significant fluidity, but provides a fine fluidity to secure the right position for the proper coupling between the upper / lower cases (100,200) It can have a role to play.

The upper case 100 and the lower case 200 will have a strong coupling relationship between the two by a more detailed configuration to be described later.

Figure 2a is a perspective view showing a detailed configuration for the lower case according to the present invention, Figure 2b is a side view showing a detailed configuration for the lower case according to the present invention.

As can be seen from Figure 2a and Figure 2b, the lower case 200 according to the present invention is made of a size corresponding to the size of the electronic device bulge 210 protruding to the upper part so that a certain portion and the peripheral portion of the bottom surface curvature ) And a plurality of through holes for smoothly operating each terminal, speaker, sensor, and the like of the electronic device.

The ridge 210 forms part of the side surface of the lower case and the lower surface of the lower case so as to surround the side portion of the electronic device. The ridge 210 is not vertically upright, but suits the shape of the electronic device. It is raised in a curved rounded state to be collected inward as it goes upward.

The supporter 220 is additionally protruded from the upper surface of the ridge 210.

The supporter 220 protrudes from the upper surface of the ridge 210 so as to have a step. In other words, the supporter 220 is located at the inner side (that is, the center of the electronic device) at the upper surface of the ridge 210. A protrusion 220 is formed, and thus, a step (step) with respect to the height occurs between the outer (outer side) portion of the upper surface of the ridge 210 and the supporter 220, and the supporter 220 is a ridge. The outer upper surface portion of the ridge 2110 is kept flat while the upper surface inner portion of the upper surface 210 is formed.

The supporter 220 also does not protrude vertically, but has a shape in which the ends protrude round so as to face the inner side (electronic device accommodation direction).

The supporter 220 performs a key function to ensure a firm coupling relationship with the upper case 100. Particularly, the supporter 220 has a lower case made of an elastic material so as to protrude rounded toward the inner side. The supporter 220 of the 200 is to have a stress to gather inward to the upper case 100 is coupled to it so as to ensure the firmness of the coupling so that they can be naturally combined while gathering inward instead of opening to the outside. Actions on this will be described below in more detail.

Coupling grooves 221 are formed in the outer wall of the supporter 220 located at four corner points.

Coupling grooves 221 formed at these four corner points are combined with the coupling protrusion 131 of the upper case 100 to be described later, providing a primary coupling force between the upper case 100 and the lower case 200. Play a role.

In addition, the coupling groove 221 may be formed in the outer wall of the supporter 220 of the left and right portions or the upper and lower portions, as well as the bottom case 200 when viewed from the top, in addition to the corner portion, and such an additional coupling groove 221. ) Is also coupled to the coupling protrusion 131 corresponding to the upper case 100 provides a function to reinforce the coupling relationship between the two.

In addition, a recess 222 is formed at one portion of the supporter 220 between the coupling grooves 221. The recess 222 protrudes from the ridge 210 at a height lower than that of the peripheral supporter 220 where the recess 222 is not formed. In other words, the recess 222 is dug lower than the peripheral supporter 220. It has a state and means a portion that is coupled to the protrusion 131 of the upper case 100 to be described later.

The recesses 222 are formed at a point other than a portion where the coupling grooves 221 are formed. More specifically, the recesses 222 are formed as one or two on the left side and the right side of the entire supporter 220. .

Figure 3a is a perspective view showing a detailed configuration of the rear center of the upper case according to the present invention, Figure 3b is a cross-sectional view showing the detailed configuration of the engaging projection formed on the upper case.

The upper case 100 wraps around the upper and side portions of the electronic device to press the circumference to prevent the electronic device from being separated from the lower case 200, and is configured to have a close coupling with the lower case 200. .

As can be seen in Figure 3a, the upper case 100 is a frame structure except the hollow portion of the center portion is standing in a curvature rounded state is generally made to correspond to the side structure of the curved electronic device of the electronic device It covers from the top to part of the side.

In detail, the frame of the upper case 100 includes first to third guides 110, 120, and 130, wherein the guide is a sidewall of the frame, the side of which extends along the circumference of the frame while looking toward the hollow portion. Each guide has a step in a stepped manner, which may be called a step, and the step may refer to a boundary part extending in a horizontal direction to distinguish each guide. It is not made of the same thickness, but is formed to have a different thickness step by step guide configuration.

The first guide 110 refers to a guide in contact with the hollow portion direction from the upper side of the upper case 100, the second guide 120 has a step (step) with the first guide 110, the first guide ( The third guide 130 is formed at an outer position farthest from the hollow portion at the lower side of the upper case 100 while having a step with the second guide 120.

By such a structure, the first and second guides 110 and 120 have stepped portions formed in substantially horizontal directions, and the second and third guides 120 and 130 also have stepped portions extending in substantially horizontal directions. Here, the expression "approximately" is used to emphasize that it does not need to extend 100% horizontally, that is to explain the extension direction.

That is, the upper case 100 can be seen that the first to third guides (110, 120, 130) are formed with a stepped inclined in a rounded form so as to narrow the width of the hollow portion toward the top.

In particular, a protrusion 132 protruding to correspond to the structure of the recess 222 of the lower case 200 in the direction of the third guide 130 from the second guide 120 is formed, and the coupling groove 221 Coupling protrusion 131 to be coupled to the () is formed to fit the number and shape of the coupling protrusion 131 in the portion of the third guide 130.

In particular, as can be seen in Figure 3b, the engaging projection 131 is formed to be slightly inclined upward and is not specifically shown in the figure is formed to match the inverted trapezoidal structure of the coupling groove 221.

Referring to the coupling relationship between the upper case 100 and the lower case 200 for the case according to the present invention having such a configuration as follows.

4 is a cross-sectional view illustrating a state in which an electronic device is accommodated between an upper case and a lower case according to the present invention.

First, when the electronic device is seated on the lower case 200, the lower case 200 may cover the ridge 210 to a part of the side surface of the electronic device while protecting the bottom surface (bottom) of the electronic device.

That is, the side of the electronic device is covered by the upper case 100 and the lower case 200 is shared, that is, the ridge 210 of the lower case 200 covers the lower portion of the side of the electronic device.

The ridge 210 is formed to be inclined inward as the upper side is raised in accordance with the curved side shape of the electronic device, so as to cover the side of the electronic device stably and collect the upper end of the ridge 210 having an elastic force inward. Loss of tension can build up the tension of the electronics more appropriately.

As described above, the upper case 100 is coupled to the lower case 200 while the electronic device is accommodated in the lower case 200. First, the side surface of the third guide 130 contacts the outer portion of the supporter 220. While the side surface of the third guide 130 is in contact with the surface formed on the outer portion of the ridge 210 and the stepped between the second and third guides (120,130) is the upper surface of the supporter 220 (protrusion top Surface of the point).

That is, the outer part of the ridge 210 in which the supporter 220 does not protrude is made to contact the stepped portion formed between the second and third guides 120 and 130 of the upper case 100 so that the upper case 100 moves toward the gravity direction. It acts as a stopper to prevent the problem of disappearing.

In addition, the side of the first guide 110 is in contact with the upper surface of the electronic device and the step between the first and second guides 110 and 120 and the side of the second guide 120 is part of the side of the electronic device (that is, The upper part of the side).

In particular, the coupling protrusion 131 protruding in the direction of the hollow portion from the third guide 130 is coupled to the coupling protrusion 131 formed on the outer wall of the supporter 220 of the lower case 200 to the four corner portions. Closer coupling relationship by providing a primary coupling force and secondarily additionally coupled between the coupling groove 221 and the coupling protrusion 131 formed in at least one other part of the upper case 100 and the lower case 200. To provide.

Specifically, since the coupling protrusion 131 is not protruded horizontally but protrudes obliquely upwards, the coupling protrusion 131 penetrates into the coupling groove in the upward direction as if to lift the coupling groove 221, thereby ensuring a more tight coupling relationship between the two. It is possible to ensure durability even in the external force acting in the lateral direction, and also to prevent the phenomenon that both are easily separated even when the external force acts by the coupling between the coupling groove 221 / coupling protrusion 131 formed in an inverted trapezoid shape. To give the property.

Since the coupling groove 221 and the coupling protrusion 131 having such a structure are made of rubber or silicon around the coupling groove 221, the coupling groove 221 is inserted into the coupling groove 221. By asking the coupling protrusion 131, even if it is made of a heterogeneous material such as rubber / silicon and metal / plastic can provide a more stable coupling relationship.

In addition, even if the upper case 100 is made of a solid material, it has a certain elasticity because the center portion has an empty frame structure, and the user covers the upper case 100 on the lower case 200 and then the user places the upper case 100. When pressing the side of the coupling protrusion 131 can be more deeply and firmly coupled to the coupling groove 221.

In addition, the protrusion 132 protruding from the second guide 120 to the third guide 130 (that is, the stepped portions of the second and third guides protrude downward) is formed in the recess 222 formed in the supporter 220. The seat coupling is to provide a role of complementing and strengthening the coupling between the coupling groove 221 / coupling protrusion 131.

 The coupling relationship between the upper case 100 and the lower case 200, that is, the coupling between the coupling groove 221 / coupling protrusion 131, the coupling between the protrusion 132 and the recess 222, the first and second guides ( The upper case 100 and the lower case 200 are formed by contact between the stepped portion 110 and 120 and the upper surface of the supporter 220 and the contact coupling relationship between the second and third guides 120 and 130 and the outer portion of the ridge 210. Multi-coupling) ensures a more robust and stable coupling to fulfill the basic mission of providing electronics protection.
