Description

Carrying Charger and Protective Case for Mobile Phone

The present invention relates to a portable charger and a protective case of a mobile phone mounted therein. More particularly, while the mobile phone is mounted on a portable charger having a built-in rechargeable battery, the mobile phone and the charger can be protected together from external shock. The present invention also relates to a portable charger with a fastening coupling force and a protective case for a mobile phone mounted thereon.

Since mobile phones are used on the move, unlike landline telephones that are powered from a fixed location, they must be powered by batteries, so batteries are of paramount importance.

These batteries tend to become thinner with the miniaturization of mobile phones. When the battery is depleted due to the use of a mobile phone, the battery needs to be recharged.In addition to an increase in the call volume, various functions such as video recording, multimedia, internet, satellite broadcasting, etc. In addition, the battery becomes more exhausted, and charging becomes more important.

In particular, the recent increase in the need for a variety of applications can be used as the number of users of smart phones, called computers in the hand.

Accordingly, as a separate charging device, the mobile phone can be charged by using AC 110 / 220V AC power or housed in a vehicle, using a DC 12 / 24V vehicle cigar power source. .

However, the above-described charging method is limited in the use of the home or office where AC power is not supplied, or when the vehicle is not in operation, it is troublesome to start and charge the vehicle separately.

From this, while carrying a spare battery separate from the mobile phone, when the battery currently installed in the cell phone is replaced when you can continue to use the mobile phone anytime and anywhere, but you need to carry the battery as described above because it is inconvenient and worry about loss In some cases, it is often broken while being carried by carelessness or external impact.

This prevents the battery from being damaged due to careless handling or external shocks, and makes it easy to carry and prevents calls from being made due to battery depletion. Portable cell phone chargers have been proposed that can be charged.

Specifically, the conventional portable cell phone charger 10 as shown in Figures 1 and 2, the rechargeable battery is built (not shown in the figure) so that the back of the mobile phone 1 abuts on the bottom surface is mounted A main body 11 and a battery output terminal 12 positioned below the main body 11 to output power of the rechargeable battery.

The main body 11 has an open upper surface and a front surface so that the screen is visible to the front side when the cell phone 1 is inserted or removed while being inserted into the upper side. In addition, the main body 11 covers and covers a part of the edge of the mobile phone 1 by both side and bottom surfaces of which the upper part is removed, thereby keeping the mounted mobile phone 1 in a fixed state. To this end, both side and bottom surfaces of the main body 11 are bent along the front surface of the mobile phone 1 to extend by a predetermined width.

The battery output terminal 12 is coupled to a power supply terminal installed on the lower surface of the mobile phone 1, and supplies the power of the rechargeable battery to the mobile phone (1). In order to mount the mobile phone 1 on the portable mobile phone charger 10, the mobile phone 1 is inserted with the power supply terminal facing downward on both sides of a portion of the upper part removed from the main body 11. After reaching the lower surface of the main body 11, the power supply terminal is pressed until the power supply terminal is coupled to the battery output terminal 12.

Then, the mobile phone 1 is charged with the power supply terminal connected to the battery output terminal 12 while being mounted and fixed while both sides and the bottom surface of the main body 11 are mounted and charged in the main body 11. Is powered by the battery.

However, in the portable mobile phone charger 10, when the mobile phone 1 is mounted on the main body 11, as shown in FIG. There is a risk of damage due to external impact generated during the use process.

From this, in the other conventional portable cell phone charger 20 as shown in Figs. 3 and 4, the lower case 21 and the lower case 21 as a main body which has a built-in rechargeable battery to perform the function of the charger. It consists of the upper case 22 covering the top in the state of inserting the power supply terminal of the mobile phone (1) to the battery output terminal 25 of the), and is fastened to the entire coupling by the fastening coupling portion (23). Here, the lower case 21 and the upper case 22 are made of hard synthetic resin material to protect the mobile phone 1 inserted from the external impact.

And even if the upper case 22 is fastened and coupled to the lower case 21, the front case is formed to be exposed to the outside by fastening and coupling to expose the front of the screen of the mobile phone 1 to the outside while various By placing switches, buttons, jacks, and other openings 24 for normal use of the camera, etc., at the corresponding positions on the rear side, the mobile phone 1 can be smoothly manipulated, while the other side and rear side of the cell phone (1 It prevents the damage caused by the impact applied to) or the scratches caused by the contact.

By the way, in the case where the mobile phone 1 is inserted and coupled to repeat the process of fastening and overall coupling while covering the upper case 22 to the lower case 21 to perform the function of the charger, the corresponding coupling portion 23 ) Weakening or breakage of the bond will not be able to function properly.

In addition, the mobile phone charger 20, the upper case 22 in the process of fastening and coupling the upper case 22 to the lower case 21, or conversely separates the upper case 22 from the lower case 21 ( 22) Loss may occur.

In addition, when the coupling force of the fastening coupling portion 23 is weakened or damaged and fails to properly function, the loss of the upper case 22 increases. In this case, as well as the possibility that the mobile phone 1 inserted into the lower case 21 is separated and detached, it is also possible to properly protect the mobile phone 1 from external shocks as in the case of the mobile phone charger 10. Unexpected problems also arise.

In addition, the portable mobile phone charger 20, although the button or switch operation of the mobile phone 1 through the corresponding opening 24 formed on the side of the case 22, the opening 24 There was also a problem in that it forms a closed path and the operation is not easy due to the side thickness between the opening part 24 and the mobile phone 1.

From this, in another conventional portable cellular phone charger 30 as shown in Figs. 5 and 6, the battery is built in the lower case 31 and the lower case 31, the cell phone is built in to perform the function of the charger (1) in the state of inserting and coupling the cover while maintaining the upper case 32 to be coupled and coupled always keeps the connected state.

That is, the lower case 31 and the upper case 32 are not separated by the separate case connection part 33 made of a material having an elastic force, and the upper case 32 is lifted aside while maintaining the connected state at all times. After inserting and coupling the power supply terminal of the mobile phone 1 to the battery output terminal 36 of the lower case 31 which is opened, the mobile phone 1 in the form of rotating the upper case 32 from the front to cover the back. The upper case 32 in a state in which the lower case 31 is fastened to the lower case 31 or the upper case 32 is inversely separated from the lower case 31. The mobile phone 1 is separated and separated through the lower case 31 which opens the upper part.

Thus, unlike the case of the portable mobile phone charger 20, there is no fear of loss of the upper case 32, while preventing the separation and separation of the mobile phone 1 inserted and coupled to the lower case 31 as much as possible to prevent external impact, etc. It is possible to properly protect the mobile phone (1).

In the upper case 32, the opening part 35 formed for normal use of a switch, a button, etc. of the side is partially opened toward the front, and in the upper case 22 of the portable mobile phone charger 20 By the side thickness between the opening 24 and the mobile phone 1 to form a closed path to solve the problem that was not easy to operate.

By the way, in the mobile phone charger 30, as in the case of the portable mobile phone charger 20, the upper case 32 is separated from the lower case 31 or the lower case 31 while the back case or the front cover. When the coupling process is repeated, the case connection part 33 and the coupling coupling part 34 become weak or damaged, and thus fail to properly function.

In addition, the portable phone charger 30, the opening portion 35 formed on the side of the upper case 32 is partially open toward the front of the open area 35 is exposed to the total area of the mobile phone 1 is increased Although it is possible to operate the button or switch more easily, in this case, since the periphery of the opening 35 is exposed to the outside, there is a risk of malfunction or damage to the button or the like.

In addition, in the conventional portable phone chargers 20 and 30 as described above, the lower case 21 and 31 and the upper case 22 and 32 are fastened and coupled to insert the coupled mobile phone 1 from external shocks. Although performing the function of protecting, the mobile phone charger (20, 30) is not a simple consumable, but is used together with the mobile phone (1), but the lower case (21) (31) that is built in a rechargeable battery ) Itself cannot be protected from external shocks, and there is a risk of damage to itself.

In addition, in the portable mobile phone chargers 20 and 30, the upper case 22, 32 and the lower case 21, 31 are exposed to the outside as it is, in order to consider the design and to prevent the occurrence of scratches Processes such as coloring or coating are added to increase the manufacturing cost and to be difficult to recycle after use.

In addition, the portable cellular phone chargers 10, 20, and 30 are made of hard synthetic resin material, so that the grip of the mobile phone charger is reduced, and even when placed on the floor, the sliding surface can be caused by the coated surface.

From this, the present invention has been made to solve the above problems, while the mobile phone is mounted on a charger with a built-in rechargeable battery, the portable phone as well as the mobile phone can be stably protected from external shocks together while also reinforcing fastening coupling force The purpose is to provide a charger and a protective case for the mobile phone mounted thereon.

According to the protective case of the portable charger of the present invention having the above-described configuration and the mobile phone mounted therein, the mobile phone is attached to the charger with the built-in battery in a state where the mobile phone is covered with the entire cover except the front, thereby ensuring the use of the mobile phone. In addition to the cell phone inserted into the cell phone as well as the battery charger that is used with the cell phone will be effective to protect against external shocks.

In this case, since the charger is not exposed to the outside, it is possible to minimize the manufacturing process such as coloring or coating in order to consider the design and prevent scratches, thereby lowering the manufacturing cost and easily recycling after use. It also works.

In addition, according to the portable charger of the present invention having the above-described configuration and the protective case of the cellular phone mounted thereon, by adopting a soft silicone material, the overall grip is soft and the grip is not only good to grip but also absorbs external shocks. It is possible to prevent or minimize damage to the charger and the charger, and to thin the side thickness between the opening and the mobile phone, so it is easy to operate. The push button does not need to form the opening unlike the hard case. Not only can it be prevented from being torn by external contact, and since the opening is not minimized or exposed to the outside of the periphery, there is also an effect of minimizing malfunction or damage of a button.

In particular, the cell phone is positioned on both sides of the upper corner when the charger and the cell phone face each other by the cell phone positioning fixing protrusions formed along the upper and left and right edges of the charger except for the both sides of the upper corner of the charger to maintain the state in which the cellular phone is mounted on the charger. By forming the charger fixing and fastening reinforcement protrusions at the internal positions corresponding to the predetermined spaces, the whole is made of a soft silicone material and immediately returns to its original state even when a part of the edges is peeled off while contacting when taken out of the pocket There is also a reinforcing effect to maintain the fastening coupling force.

In addition, by forming a front opening edge extension that extends by a predetermined width while bending to the front of the mobile phone along the edge of the front opening, it minimizes slippage from the characteristics of the soft material even when placed on the floor. As the gap is formed, there is an effect of preventing the occurrence of damage or scratches.
