Description

[0001] The present invention relates to a case for a mobile device,

[0001] The present invention relates to a case for a portable device in which an accessory can be easily attached and detached, and more particularly, The present invention relates to a case for a portable device which is easy to attach and detach.

In modern society, mobile devices, especially mobile phones, have a great impact on people's lives. Most of the functions performed by conventional desktop computers such as music listening, surfing the Internet, paperwork, games, and the like are implemented as mobile devices, as well as phone calls for the initial purpose of the mobile phone.

However, as the multiple functions are implemented, the degree of integration of the portable devices increases, and as the size of each component becomes smaller, the probability of damage and failure due to the impact is increasing. Especially, the front liquid crystal which occupies the largest part of the portable device is exposed on the front surface, and since the glass which is weak in impact is used as the main material, the damage caused by most impacts is concentrated on the front liquid crystal display device .

The portable device case is generally provided on the rear surface of the portable device, and the portable device is inserted and fixed in the concave portion of the front surface 10 of the portable device case. Generally, since the case made of a polymer material has elasticity, it can be pressed on a concave portion of the case 10 to provide a portable device. When the case is made of a metal material, the case does not have elasticity , The mobile phone can be manufactured without an upper surface or a side surface of the case, and the mobile device can be inserted by sliding in the upper surface or one side direction. It is also possible to attach and fix additional accessories that can be installed on the upper surface or one side surface after the insertion as described above.

The case may be made of a polymer, metal, carbon, or ceramic, but titanium or an alloy thereof may be used. Titanium is a non-toxic light metal used in transplantation of body tissues. It has high affinity for human body, so it has little effect on the human body even when it comes into contact with the human body for a long time. In addition, the strength of pure titanium is 30 ~ 75kgt / ㎟, and titanium alloy is 60 ~ 160kgt / ㎟, so that case with high strength can be manufactured. Finally, in the case of titanium, a titanium oxide film is formed naturally on the surface. Since the titanium oxide film is very resistant to corrosion, it is possible to prevent corrosion and oxidation due to water, detergent, sweat, have.

The titanium oxide film may be formed by anodizing. Anodizing is an anodizing method, and titanium can have various colors depending on the voltage applied during anodizing. However, since the color due to the change of the voltage is limited, it is also possible to produce a case of a desired color by coloring after anodizing.

In addition, titanium oxide (TiO2), which is a main component of the titanium oxide film, is used in various fields as a catalyst and acts as a catalyst for decomposing microorganisms and organic substances when in contact with microorganisms. Therefore, It can have a sterilizing effect.

In the present invention, the case for the portable device may further include openings 11 and 21 for operating a sensor, an operation switch, or a camera existing on a side surface or a rear surface of the portable device, 10 to 50% are opened (11, 21), so that the operation of the sensor, the operation switch or the camera existing on the side surface or the rear surface of the portable device can be smoothly performed. When the case for a portable device is made of a polymer compound, operation of some switches and the like can be performed by the elasticity of the polymer compound, but an opening necessary for driving a camera or a sensor is required. In addition, when the portable device case is made of a metal material, particularly titanium or a titanium alloy, an opening for the switch as well as an opening for the camera and the sensor are also required. Therefore, it is preferable that the case is further provided with openings 11, 21 for each camera, sensor and switch. Further, 10 to 50% of the side or rear surface may be opened (11, 21) so that the camera, the sensor and the switch can smoothly operate instead of installing the opening.

In the present invention, an opening (100) is provided below the rear surface of the case and through the portable device case. The opening 110 is a portion to which a connection unit 150 of the expansion device to be described below is inserted and coupled.

The expansion device may include a battery, a charging means, a storage space expansion means, an audio sound quality improvement means, a loss prevention alarm means, or an additional connection terminal, or two or more of them may be installed in combination. In addition, since the extension device is connected to the external terminal 120 installed in the case, unlike the existing expansion device, when the extension device compatible with the external terminal 120 is used, It is compatible with any kind of system.

In addition, a connection unit 150 is formed on the front surface of the expansion device, and when the connection unit 150 is connected to the inner surface of the connection unit, the external terminal 120 for communication and charging of the portable device case, Since the connecting terminal is in contact with the connecting portion 150, when the connecting portion 150 is inserted into the opening 100 and then the expanding device is slid downward, corresponding electrodes can be naturally connected. In addition, the connection terminal may be smoothly inserted by the slide, and a spring electrode may be used for smooth contact with the external terminal 120. The spring electrode is an electrode capable of entering and exiting by the pressure. The spring electrode is contracted according to the movement of the connection part 150 while the extension device is slidably inserted, and after the insertion is completed, So that the contact of each electrode can be made smooth.

Further, when the extension device is connected to the case only by the connection part 150, there is a danger that the connection part 150 may be damaged due to an impact. Therefore, the expansion device and the portable device case may have additional connection parts 140 To prevent breakage of the connection portion.

When the external terminal 120 is exposed, oxidation may occur on the electrode on the terminal, and the contact performance of the terminal may be deteriorated. In addition, since the external terminal 120 is used for charging, when the metal contacts the electrode, a failure due to a short circuit may occur. Therefore, it is preferable that the external terminal 120 is provided inside the case and under the opening to prevent damage due to corrosion or short-circuit.

Also, the external terminal 120 is made of a conductive metal and may have 1 to 10 flat electrodes. The electrode is a means for performing charging and data communication of the portable device by being connected to the corresponding internal terminal 130 and corresponding electrodes. The electrode may be formed as a plate-shaped electrode to facilitate insertion of the connection portion. In addition, the external terminal 120 is designed to include all the electrodes used for connecting the portable device, so that the external device 120 can be compatible with the expansion device even if the portable device is changed. For example, when the external terminal is manufactured to include electrodes such as GND, TX1 +, TX1-, Vbus, CC1, D +, D-, SUB1, RX2-, and RX2 + The extension device can be used in a compatible manner.

In the present invention, the case for the portable device is located inside the lower surface of the case, the external terminal 120 is electrically connected to the corresponding electrode, and the portable device communication and charging internal Terminal 130 as shown in FIG. The internal terminal 130 may be formed in a shape corresponding to a terminal provided in each portable device. In general, terminals used in portable devices are USB 2.0 Micro type B, 8 pin lightning, USB 3.0 Micro type B, and USB 3.0 type C, and they are used depending on the type of each portable device.
