Smartphones are like a kind of small computer with the front part of the main body mostly made of monitor liquid crystal. Therefore, the smart phone can search various information and watch videos, store data such as electronic books in the built-in memory, and read it through the monitor.

These smartphones with various functions are small in size, but they are expensive products that are sold at similar prices to ordinary laptops. Therefore, the maker is designed to maintain the strength that will not be destroyed even if the smartphone is dropped.

However, ordinary consumers prevent expensive smart phones from being damaged, and they also use separate cases to prevent scratches such as scratches on the main body and monitor due to various external factors.

The smartphone case can be divided into a case for protecting only the side portion of the main body excluding the liquid crystal, and a case having a cover for protecting the liquid crystal portion.

Among these cases, the case protecting only the main body is mainly used by those who place importance on the portability of the smartphone, and a separate protective film for preventing scratching is attached to the liquid crystal.

The case with the lid is made up of the lid having a pocket and a card for storing a small amount of cash. The cover is folded back into the case to add a cradle to allow the smartphone to be raised at an angle, and users with a variety of smartphones and always-on users prefer a case with a cover.

However, it is common for smartphone users to choose one of these cases, and it is very rare to use two types of cases crossing each other.

In other words, although a lot of smartphones are used, users who want to use the ones without a cover do not want to increase the bulky size of the smartphone, .

In addition, some drivers use the smartphone as a navigation system, and when using the smartphone as a navigation device, the smartphone must be mounted on the vehicle. In such a case, it is preferable that the case has no cover.

Therefore, depending on the characteristics of the user and the purpose of use, the case may or may not have a cover.

Therefore, even if you reduce some inconveniences, it is a reality that many users are not satisfied with the case that they are using only the case which is suitable for their use environment.

Therefore, a lid fastening portion 11 of a wedge shape is formed on one side of the rear surface of the case body 10, and a support plate 20 is formed on the lid fastening portion 11 to be rotated to one side.

In addition, a card insertion groove 19 may be formed in the case body 10 to insert the card concave on a flat surface. The card inserted into the card insertion slot 19 is intended for insertion of a traffic card, an access card, or the like, rather than a card used for purchasing and payment of goods.

Traffic cards and access cards are used by short-range communication to confirm identities between devices and to conduct small financial transactions. It is a way for a reader to check card information by short distance communication without confirming the presence of the card. Therefore, it is not necessary to be exposed to the outside. However, these cards have to be used several times a day, so it is very convenient to attach them to smart phones.

Therefore, in the case body 10 of the present invention, a card insertion groove 19 for accommodating such a card is formed.

The support plate 20 is a stick-shaped plate having a predetermined length, and both upper and lower ends thereof are coupled to the case body 10 so as to be rotated. The support plate 20 is normally in close contact with the case body 10 and is rotated to the outside only when the user needs to open the smartphone.

That is, the support plate 20 is normally inserted into the lid fastening portion 11 of the case body 10 so that the support plate 20 can not be confirmed as long as the support plate 20 is not particularly interested in the outside. Therefore, the support plate 20 can not be clearly distinguished from the case body 10 in appearance. However, the support plate 20 is rotated to the outside of the case body 10 when the user needs to perform the function of the smartphone holder.

The cover 30 protects the liquid crystal of the smartphone and is used to store simple personal items such as a card, an identification card, and a business card inside. In the present invention, the case 30, A function of separating or coupling is provided.

The lid 30 is formed with a fastening plate 31 on one side and the fastening plate 31 is separated or fastened to the case body 10 so that the lid 30 is engaged with or separated from the case body 10. [ to be.

More specifically, the lid 30 can be fastened to the case body 10 by inserting the fastening plate 31 into the lid fastening portion 11 of the case body 10. That is, the support plate 20 attached to the lid fastening portion 11 of the case body 10 is rotated to open the lid fastening portion 11 and then the fastening plate 31 of the lid 30 is fastened to the lid fastening portion The fastening plate 31 is fixed between the case body 10 and the support plate 20 and the cover 30 is fastened to the case body 10 by fixing the fastening plate 31 on the upper surface of the fastening plate 31, Is fixed.

A method of separating the lid 30 from the case body 10 may be performed in the reverse order of engagement.

4 and 5, the support plate 20 and the fastening plate 31 may be further formed with additional structures to further secure the coupling between the case body 10 and the lid 30. For this purpose, the support plate 20 may be provided with a coupling protrusion 21 on a surface thereof in contact with the case body 10, and the coupling protrusion 21 of the support plate 20 is inserted into the coupling plate 31 of the lid 30 The engaging groove 32 may be further formed.

When the support plate 20 is tightly coupled to the case body 10, the coupling protrusion 21 and the coupling groove 32 are engaged with each other. Due to the coupling groove 32 fitted to the coupling protrusion 21, (30) is prevented from being separated from the case body (10).

In addition, the support plate 20 may be further configured to prevent separation from the case body 10 in a state in which the user does not intend. A magnet 22 may be formed inside the engaging projection 21 of the support plate 20 and at the point of contact with the engaging projection 21 of the case body 10, The metal chip 12 may be formed to be in contact with and bonded to the metal layer 22.

In the case where the metal plate 12 is formed on the case body 10 and the magnet 22 is formed on the support plate 20 as long as the user does not intentionally separate the support plate 20 from the case body 10 The support plate 20 is not separated from the case body 10.

A magnet 13 may be formed on the back surface of the case body 10 in parallel with the magnet 22 of the support plate 20 on the other side opposite to the support plate 20. Therefore, magnets 13 and 22 are attached to the back surface of the case body 10 at both side ends thereof in an 11-shape.

The provision of the magnets 13 and 22 parallel to both sides of the back surface of the case body 10 is intended to fix the smartphone to the object more conveniently. That is, we attach smart phones to various objects made of metal that can be attached to magnets such as metal fire doors, metal railings,

It is preferable that at least four or more magnets 13 and 22 are attached to the back surface of the case body 10 and that the magnets 13 and 22 do not have a large magnetic force. This is because the weight of smartphones developed and sold in recent years is less than 200g. That is, even if the magnetic force is not large, when four or more magnets 13 and 22 are attached to the four sides of the back surface, one magnet is responsible for a load of 50 g or less, so that there is no problem in attaching the smartphone to the metal wall .

5 to 7, when the case body 10 and the cover 30 are coupled by the coupling protrusions 21 and the coupling recesses 32, the coupling protrusions 21 and the coupling recesses 32 A slight clearance may occur due to machining tolerances. This is not a perceived level of human perception, but some sensitive users may consider it a serious flaw.

[

A magnet 15 is provided in the hollow portion 18 and a magnet 15 inside the protruding protrusion 17 is inserted into the magnet 16 of the support plate 20 22 in the pulling direction with respect to each other.

When the magnets 15 and 22 are present on both sides, a force is applied between the magnets 15 and 22 so that the supporting plate 20 can be more firmly fastened to the case body 10. [

In addition, since the magnet 15 of the case body 10 exists in the protruding step 17, the magnet 15 can be prevented from being lost to the outside of the case body 10 during use, .

The magnets 13 are present in the inside of the protrusion 17 of the lid fastening portion 11 and inside the other side of the case main body 10 parallel to the lid fastening portion 11. [ The magnets 13, 15, and 22 used in the present invention have a small magnetic force and do not particularly affect the operation of the smartphone.

However, in the present invention, in order to fundamentally block the influence of the magnet 13, 15, 22 on the operation of the smartphone, a shielding plate (not shown) for blocking the magnetic force of the magnet between the magnets 13, 16 may be provided.

The shield plate 16 used in the present invention is intended to prevent the magnetic force of the magnets 13 and 15 of the case body 10 from affecting the smartphone, and a thin metal plate can also be expected to have an effect. The shield plate 16 used in the present invention should be easy to get into the case body 10, and a thickness of 0.5 to 1 mm is sufficient for this purpose.

It is preferable that the shielding plate 16 is formed in a larger area than the magnets 13 and 15, and it is sufficient that the shielding plate 16 deviates from the side of the magnet by 3 to 5 mm.

The shield plate 16 made of a thin plate can sufficiently prevent the magnetic forces of the magnets 13, 15, and 22 from affecting the smartphone, and has an effect of sufficiently preventing an abnormal operation from occurring in the smartphone.
