First, the case 10 according to the present invention may provide a basic function of preventing scratches from occurring in the portable electronic device 1, and in particular, may prevent the portable electronic device 1 from being damaged by an external impact. The main function is to strengthen the external shock absorbing function.

The term 'portable electronic device' (1) as used in the present invention means a device that is made of a size that a user can carry / store in a pocket, a hand, a bag, and the like, and can provide various communication, games, and video viewing functions. And smart phones, mobile communication terminals, MP3 players, and video players.

Among these, the most commonly used portable electronic device (1) is a bar type smartphone (Samsung's Galaxy S / Note series, LG's Optimus, etc.) with a display panel exposed on the front, and Pantech. Vega series, Apple's iPhone series, etc.) This smartphone is highly likely to drop on the floor due to the inadvertent nature of the communication device, and in fact, such accidents occur frequently, the case of the present invention is As described above, the core of the present invention is to provide a function for preventing damage / damage problems caused by the fall of the portable electronic device around the smartphone.

As can be seen from Figures 1 and 2, the case 10 of the present invention is composed of a structure covering the side (including a part of the front circumference) and the back of the portable electronic device 1, specifically, the first and second bodies It consists of a combination of (100,200).

The first body 100 is composed of a structure covering the side of the portable electronic device 1 (four sides because the portable electronic device mainly consists of a rectangular shape) and the back (opposite side of the display panel of the portable electronic device) In addition, the second body 200 is formed in a band shape with an inner hole, and is coupled to the side surface of the first body 100 in a manner that is overlaid on the side surface of the first body 100 (specifically, on the surface of the first body). In close contact with).

As can be seen from Figure 2, the case 10 of the present invention by covering the second body 200 on the side of the first body 100 in a state in which the first body 100 is first coupled to the portable electronic device It is coupled to the portable electronic device (1).

That is, the first body 100 itself also provides the basic function of protecting the side and the back of the portable electronic device 1, but especially when the user accidentally dropped the portable electronic device 1 by the external force. In order to prevent the first body 100 from being separated from the portable electronic device 1, the second body 200 is pressed against the first body 100, and further, by the first and second bodies 100 and 200. The side portion of the portable electronic device 1 is to protect the double.

As can be seen from Figures 1 and 2, the first body 100 of the present invention has a side protection unit 110 covering the side of the portable electronic device 1, and the rear protection covering the back of the portable electronic device 1 Comprising the portion 120, the overall shape of the first body 100 has a container shape of the upper portion is open.

The side protection part 110 is formed to correspond to the side shape of the portable electronic device 1, and since the side surface of the portable electronic device 1 is generally composed of a flat surface or a rounded curved surface, the side protection part ( 110 may also have a structure corresponding thereto.

The back protection part 120 is bent from the side protection part 110 to cover the entire back surface of the portable electronic device 1, and may be made of a flat surface or a curved surface according to the back shape of the portable electronic device 1. Do.

By the side protection unit 110 and the rear protection unit 120, as described above, the first body 100 has a container shape of which the upper part is open, and the side and the rear surface except for the front of the portable electronic device 1; Accommodate portable electronic devices in contact.

In addition, although not shown in the drawing, it is also possible to protect the front of the portable electronic device 1 by opening and closing by forming an openable front cover on the first body 100.

The second body 200 of the present invention is formed in a band shape of a closed curved surface to cover the side protection part 110 of the first body 100, which is the first body 100 when only the first body 100 is provided. When the body 100 is easily detached from the portable electronic device 1 or the portable electronic device 1 on which the first body 100 is mounted is dropped, the first body 100 is detached from the portable electronic device and the mounting shock This is to block the harm that does not play an absorption role.

 The second body 200 should be made of a material that is hard enough to press the first body 100 and the portable electronic device 1 to a certain level, but made of metal or synthetic resin, but more easily. More preferably, it is formed from a plastic based material such as polycarbonate which can be injection molded and thermoformed.

In contrast, the first body 100 does not necessarily need to be made of a hard material, but may be made of a plastic-based material (eg, rubber) that is softer than the second body 200, thereby intensively absorbing shocks. More preferably.

That is, while the first body 100 of the soft material wraps around the second body 200 of the hard material, the first body 100 is not easily separated from the portable electronic device 1 and is made of a single body. Compared to the known case, the external force can be dispersed in the first and second bodies (100, 200), and the user's grip can be improved, and the aesthetic sense can be expressed, and the side of the portable electronic device can be determined by the second body 200 itself. It will provide a role to protect.

A plurality of through holes 130 and 210 are formed in the first and second bodies 100 and 200, so that the speaker, the power port, the volume control button, and the camera of the portable electronic device 1 can be exposed to the outside. Since it provides a function and action similar to known through-holes, a separate description is omitted.

In addition, when the outer surface of the side protection part 110 of the first body 100 is simply a flat surface, the second body 200 coupled thereon may slip, and thus, the side protection part 110 ) Is a second body mounting area (inwardly embedded between the loop 111 (upper end / upper edge of the side protector) and the base 112 (lower end / lower edge of the side protector) serving as an upper and lower end ( 113) (i.e., the recession area between the loop and the base).

As a result, the height of the second body 200 is slightly lower than the overall height of the side protection part 110 of the first body 100 to correspond to the second body mounting region 113 to form the second body 200. Contacts the second body mounting region 113, and the second body 200 is moved up and down by the loop 111 and the base 112 formed as upper and lower edges of the second body mounting region 113. It is desirable not to flow.

The combination of the first and second bodies 100 and 200 is similar to the combination of the main body and the auxiliary body of the applicant's patent No. 988204, but improved and complemented the configuration, in particular the side protection portion of the first body ( The shock absorbing block 300 provided in 110 will be described in detail.

Figure 3 is a perspective view showing a side configuration of the first body of the present invention, Figure 4 is a cross-sectional view showing a shock absorbing block and the peripheral configuration in the first body of the present invention.

Shock absorbing block 300 of the present invention is formed in the lower region of the side protection portion 110 when viewed from the top, that is, the side of the base 112 of the side protection portion 110, the side of the protection portion 110 It is extended along the circumference (as can be seen from the figure, four side circumference) is formed extending in a state separated by a predetermined length by the partition wall (350). In other words, the shock absorbing block 300 is formed in a plurality of joining with the partition wall 350 interposed along one side of the side protection part 110.

At this time, the length (horizontal length) of the shock absorbing block 300 may be kept constant, but may be formed alternately long and short length in order to make a difference in the concentration of shock absorbing, in particular, the first body 100 In the corner portion of the side protection portion 110 of the shorter than the other portion is made of a tighter, the conventional problem that the damage of the portable electronic device 1 is severe when hitting the ground from the edge of the portable electronic device 1 in general Can be more responsive and prevented.

The shock absorbing block 300 performs a function of absorbing external shocks, that is, increases the area of the first body 100 to disperse the shocks and concentrates the shocks according to the recessed structure. 1 When the body 100 is made of a soft material such as rubber can also provide a shock absorbing function by the elastic action.

Particularly, the partition wall 350 is shorter than the length of each of the shock absorbing blocks 100 formed in plural along the circumference of the side protection part 110, and the partition wall 350 has the shock absorbing block 300 without the partition wall. Each continuous shock absorbing block prevents the side protection part 110 itself from crushing when it is continuously extended by the date (including a support function that allows the shock absorbing block to maintain its shape without being pressed in the direction of gravity). The external shock is distributed to the 300 to provide a function of focusing the shock absorbing function in the shock absorbing block 300 itself.

In addition, it is preferable that the shock absorbing block 300 is formed at the lower end of the side protection part 110, in particular, when the user accidentally drops the device while operating the portable electronic device 1 so as to contact the ground from the back portion. This is to form a shock absorbing block 300 near the rear surface to absorb the shock instantaneously.

Referring to FIGS. 3 and 4, it can be seen that the bottom surface of the shock absorbing block 300 has a portion where the step 330 is formed and a portion that does not have the opening 340.

In particular, as can be seen in Figure 4, the step 330 is formed to protrude stepped on the top of the base 112, and serves to reinforce the shock transmission function to the shock absorbing block 300 by the base 112. In other words, it provides a complementary function to smoothly absorb the shock acting in the direction of gravity than when the base alone.

In addition, the opening portion 340 is not formed, such that the step 330 is formed directly to the base 112, and consequently refers to a portion having a longer vertical length (vertical) than the site where the step is formed, this opening portion 340 The coupling protrusion 220 of the second body shown in FIG. 2 is coupled to.

That is, since only the surface contact coupling of the first and second bodies 100 and 200 may cause the coupling force to be weakened, at least one or more coupling protrusions 220 extending inward from the inner side of the second body 200 may be provided at each side. It is formed, but the opening 340 that is a groove that can accommodate this is formed in the shock absorbing block 300, which is a corresponding point in the coupling protrusion forming portion to be combined with each other uneven.

As a result, the shock absorbing block 300 may additionally provide a function of performing concave-convex coupling with the coupling protrusion 220 of the second body 200, and consequently, further strengthening of the first and second bodies 100 and 200. Combined force can be given.

The shock absorbing block 300 may be formed by joining at any one of the inner surface, the outer surface, and the inner and outer sides of the side protection part 110.

That is, although the drawing illustrates that the portable electronic device 1 is formed in the direction in which the portable electronic device 1 is positioned on the outer side of the side protector 110, the present invention is not limited thereto. The second body 200 may be recessed in the direction in which the second body 200 is positioned, or may be formed on both inside and outside sides of the side protection part 110. However, in order to ensure a coupling relationship with the coupling protrusion 220 to be described later, the shock absorbing block 300 may be most commonly formed on the outer surface of the side protection part 110.

The shock absorbing block 300 is generally formed to be joined at a predetermined height at a right angle to the inner side of the second body mounting region 113 in a direction perpendicular to the surface of the second body mounting region 113. As can be, one of the two corners formed in the entry site, preferably a rounded entrance portion 310 which is processed by cutting the corner of the opposite side of the base 112 rounded.

Due to the rounding entry portion 310, the shock absorbing block 300 has a wider height (width) at the entrance portion and gradually narrows, and ends of the inner extension portion 320 extending while maintaining the same narrowed width. Up to indentation can be formed.

The rounding entry portion 310 is to prevent the problem that the two surfaces at the entry portion of the shock absorbing block 300 easily hit by the external impact acting in the direction of gravity, so that the impact is not absorbed properly and is distributed to the surroundings. In other words, open the inner entrance portion of the shock absorbing block 300 more naturally so that the two surfaces between the entry portions do not easily collide with each other by the impact to induce the impact inward, and more naturally along the rounded curved surface. It is possible to induce an external shock into the shock absorbing block 300.

The base 112, which is in contact with the bottom of the shock absorbing block 300 and forms the bottom of the second body mounting region 113, performs a basic function of maintaining and supporting the shape of the shock absorbing block 300. It is possible to extend to the outside longer than) is called an extension base (extension base) (112a).

That is, the extension base 112a extends further to the outer side (outside the second body) than the loop 111, and the second body 200 closely coupled to the second body mounting region 113 does not slide in the direction of gravity. In addition to providing a function of not supporting, the external shock is concentrated to the shock absorbing block 300 while providing a shape maintaining and supporting function capable of maintaining a normal shape of the shock absorbing block 300 when there is no external shock.

In addition, the loops 111 and the base 112 (including the extension base) have edges due to their thickness, and if the edges are angled, there is a risk of injury to the user or the second body 200 may have a second edge. Unnecessary steps may occur when coupled to the body mounting area 113, so that the loop 111 and the base 112 (including the extension base) are inclined to one side of the protruding end as shown in FIG. A slope 150 is provided.

That is, when the second body 200 is coupled to the second body mounting region 113, the slope 150 smoothly connects both ends of the second body 200 to the first body 100 to sense a foreign body. It serves to block the problem of giving or scratching the user's body.

Referring back to FIG. 2, the inner surface of the rear protection unit 120 of the first body 100 (the surface abutting the rear surface of the portable electronic device 1) is further provided with a pattern groove 140 formed as a specific pattern. You can see that.

In other words, if the shock absorbing block 300 absorbs the shock acting on the side of the portable electronic device 1, the pattern groove 140 provides a role of absorbing the shock acting on the rear side. Furthermore, when the first body 100 is made of a soft / soft material, when the impact occurs due to the recessed space of the pattern groove 140, the entire body or part of the first body 100 is flexibly elastically absorbed or absorbs the impact itself. It provides the ability to do so.

The pattern groove 140 may be formed in various patterns over the entire portion of the rear protection part 120, thereby providing an additional function of reinforcing an aesthetic / design aspect.

Further, although not shown in the drawing, the pattern groove 140 may be further formed around a portion where the shock absorbing block 300 is formed in the side protection part 110.

That is, when looking at the side protection unit 110, the portable electronic device 1 equipped with the case 10 of the present invention may hit the ground from the back portion, but in order to prevent this problem, a separate shock absorbing space is provided. It is also possible to form the pattern groove 140 to be provided around the impact absorbing block 300 forming portion, for example, in the upper portion of the side protection portion 110 in FIG.

In this case, probability that the durability of the side protection part 110 itself may be reduced due to excessive space generation may be generated, but in this case, the loop 111 may be formed as an extension loop that protrudes outward like the extension base 112a, The material of the portion where the shock absorbing block 300 and the pattern groove 140 are formed is supplemented by forming a harder material than a double material (for example, two soft materials or a stacking combination of hard materials and soft materials) or rubber. You may.

In summary, the shock absorbing block 300 of the present invention and its surrounding configuration can elastically and intensively absorb external shocks applied to the portable electronic device 1, thereby preventing damage to the portable electronic device 1. In particular, it also plays a role of mediating the uneven coupling with the second body 200 to provide a property that can ensure a close coupling relationship between the first and second bodies (100,200).

5 is a cross-sectional view showing a first modified embodiment of the shock absorbing block of the present invention, Figure 6 is a cross-sectional view showing a second modified embodiment of the shock absorbing block of the present invention.

First, the modified embodiment according to FIG. 5 will be described, in which the inner extension portion 320 of the shock absorbing block 300 becomes narrower toward the end, and is formed of a tapered portion 321 which is tapered. It can be seen that.

The taper 321 may reinforce the concentrated effect of inducing an impact inward while maintaining the shape of the shock absorbing block 300 more naturally than when the inner space of the shock absorbing block 300 extends in a straight shape. .

Although not shown in the drawing, it is also possible to form a separate shock absorbing groove made of a hollow space at the inner end of the tapered portion 321 so that the shock induced in the inner end can be concentrated in the shock absorbing space. .

The modified embodiment according to FIG. 6 includes a bent portion 322 in which the inner end of the inner extension portion 320 of the shock absorbing block 300 is bent in one direction, and a portion having a thickness thicker than that in the lower direction is provided. By bending in an upward direction, the inner portion of the shock absorbing block 300, that is, the internal structure of the first body 100 provides a characteristic that can be induced to absorb the shock.

Although the bent portion 322 may be bent in the same width as shown in FIG. 6, although not shown in the drawings, the bent portion 322 is bent to have a wider width toward the inner end, and thus, the bent end has been widened. It is also possible to intensively receive shocks, such as shock absorbing grooves in the system.

As described above, the configuration and operation of the portable electronic device case having the shock absorbing function according to the present invention are described in the above description and drawings. However, the present invention is not limited to the above description and drawings. And it is to be understood that various changes and modifications may be made without departing from the spirit of the invention.
