1A is a perspective view of the back cover 1 of the smartphone according to the present invention. FIG. 1B is a sectional view taken along the line a-a of FIG. 1A, and FIG. 1C is a perspective view showing the back cover 1 facing the smartphone.

Referring to these figures together, the smartphone back cover 1 of the present invention includes a base 2 having a long flat shape covering the back surface of a smart phone and a frame portion 4 covering the side surface. The rim 4 extends downwardly from the base 2 integrally and preferably has the same height as the side surface of the smartphone.

The base (2) and the rim (4) are integrally formed of soft or hard plastic or rubber.

One of the improvements of the smartphone back cover 1 of the present invention resides in that a resilient rib 6 is provided adjacent to the border of the rim portion 4 around the entire outer periphery of the base 2. [ The ribs 6 are formed on the surface of the smartphone facing the back surface. The height of the ribs 6 is preferably about 1 mm. In this case, since the ribs 6 provide a margin of the clearance space having a space of about 1 mm from the back surface of the smartphone with which the base 2 touches, the base 2 is in direct contact with the device of the smartphone, It is possible to prevent an accidental pressing of the speaker or the operation button.

In addition, a speaker for transmitting sound is provided on the back of the smartphone, and the volume of the sound emitted is vibrated within the clearance space to amplify the volume. When the thickness of the ribs 6 is thin, the high-frequency sound is amplified. If the thickness of the ribs 6 is large, the deep sound is amplified. Therefore, the user can increase the output of the speaker by installing the back cover 1 of the present invention.

 According to another embodiment of the present invention, in addition to the rib 6, a reinforcing rib 8a having a height of about 1 mm may be further provided between the boundary line of the base 2 and the rim portion 4. [ Then, the free space can be secured more securely.

Conventionally, there has been a problem that the case of the smartphone malfunctions due to the tight contact with the smartphone. However, according to the improved structure of the present invention described above, the smartphone and the back cover 1 can be opposed to each other with small clearance by the ribs 6 and the elasticity of the cover 1, that is, the rib 6 itself The space can be stretched and deformed. Therefore, it is possible to reliably prevent the malfunction of the device from occurring even if the use conditions such as external pressure are changed, and the effect of amplifying the volume of the speaker is exerted.

FIG. 2A is an entire perspective view of a smartphone back cover 1 according to another embodiment of the present invention, and FIG. 2B is a cross-sectional view taken along line b-b of FIG.

1A, the ribs 6 are formed in a rectangular shape in an upper region where function buttons of the smartphone are concentrated.

Even in this case, it is possible to prevent the same effects as those of the above-described embodiment, particularly the accidental pushing of the buttons related to the camera lens, the speaker volume, or the operation of the apparatus. In addition, since a speaker of a smart phone is installed in this area, the effect of increasing the volume can be expected as described above.

It is a matter of course that the rib 6 mounting region can be located at a position other than the region shown in Fig. 2A as long as the same effect is achieved.

3 is an entire perspective view of a smartphone back cover 1 according to another embodiment of the present invention.

Another improvement of the smartphone back cover 1 according to the present invention is that the upper part in which the camera lens, the speaker and / or the device ON / OFF release button is arranged in the back cover 1 is opened and closed by the window 10 It is installed in cover.

The window 10 includes a long side 10a and a relatively short side 10b. On both sides of the upper side, a small grip portion 12 having a rectangular shape protrudes outward. The grip portion 12 is fastened to a not-shown latching groove formed on the outer side of the rear cover 1, and the window 10 is closed in the state of FIG.

A bag 10c for accommodating the window 10 is formed inside the rear cover 1 when the window 10 is slid downward and opened. The height d1 of the window 10 is larger than the height d2 of the turret 10c so that the grip portion 12 protrudes outward even when the window 10 is accommodated in the turret 10c, The window 10 can be closed by holding the paper 12 and moving the window 10 up again.

The window 10 is included in the rear cover 1, and it is convenient in terms of both production and production that it is integrally formed as a function.

It is preferable that the window 10 is made of an opaque material, at least the area of the camera lens is opaque. This is because the camera lens is not exposed when the window 10 is in the closed state, and even if the camera 10 is photographed by a malfunction, the window 10 is blocked and a proper image is not generated. Therefore, misunderstandings due to inappropriate or unnecessary image shooting to be.

Although the sliding opening and closing window 10 has been described above, various modifications are possible, for example, the bottom surface 10a or the side surface 10b is a reference fold line and the remaining portion is provided with, for example, a velcro tape or a zipper.

Although the window 10 covers various function buttons on the back side of the smart phone, it is not limited to the area covering the camera lens, for example.

4 is an overall perspective view of a smartphone back cover 1 according to another embodiment of the present invention.

In the back cover 1 of Fig. 4, an attachment structure 20 for inserting a holder 30 of a cellular phone is formed. The holder 30 includes a ring 32, a central circular fixing portion 34 to which the ring 32 is inserted and supported, and a " spike " ring portion formed at the lower portion of the circular fixing portion 34. [

The attachment structure 20 of the back cover 1 has a central groove 22 for receiving the circular fixing portion 34 and a guide 24 for communicating with the central groove 22 and extending up and down to receive the ring portion, . The width of the guide 24 is almost the same as the width of the annular portion, so that the user presses the annular portion by hand to engage with the attachment structure 20, and when not necessary, the annular portion is forcedly separated to the outside. Alternatively, a pressure-sensitive adhesive may be applied to the lower surface of the ring portion, or may be attached to and detached from the attachment structure 20 by attaching a Velcro tape.

Next, FIGS. 5 and 6 show another embodiment of the present invention in which a slim sheet-like article such as a credit card or a transportation card can be stored.

5, a concave groove 2b capable of accommodating a credit card is formed in the base 2, and the concave groove 2b can be opened or closed by being pivoted laterally with respect to a pivot shaft (not shown) And a lead 2a is provided. The leads 2a are made to have a size that occupies a substantial portion of the base 2. [ It is possible to change the lead 2a so as not to pivot but to slide.

6, a concave groove 2b 'capable of accommodating a credit card is formed in the base 2, and the concave groove 2b' is vertically rotated with respect to the pivot axis to open or close the concave groove 2b ' A flip 2a 'is provided. Since the flip 2a 'can be installed only on the lower portion of the base 2, a more beautiful and compact storage structure can be realized as compared with Fig.

While specific embodiments of the invention have been described herein with reference to the drawings, it is to be understood that these are exemplary and do not limit the scope of the invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
