The present invention relates to a mobile communication terminal using a sliding method, and more particularly, to a mobile communication terminal using a sliding method capable of operating a mobile communication terminal by sliding two parts relative to each other or opening and closing a key input unit of the terminal. It is about.

Conventional telephony communication is a method of communicating by calling the other party also in a fixed position in a fixed position. Of course, there are portable cordless phones, but they are used only for special purposes or for communication within a certain area. However, mobile communication completely solves the disadvantage that communication is impossible unless the calling party is in the place. Accordingly, mobile communication refers to a radiotelephone communication in which a mobile object such as a car, an aircraft, a train, a ship, or people in walking can communicate with each other or with a counterpart in a fixed position. A device made to transmit data or view data using such a mobile communication is called a mobile communication terminal.

Currently used mobile communication terminals are PDAs (Personal Digital Assistants) terminals, mobile phones, smart phones, and the like. Since the mobile communication terminal is mainly intended for portable purposes, the small size is preferred, and the design is special, but it is additionally preferred to include various functions. Therefore, in the mobile communication terminals that are being released these days, small and thin products are continuously released, and light weight and excellent design are preferred.

In general, mobile communication terminals may be classified into a flip type, a folder type, and a sliding type according to their appearance or operation method.

In general, the flip method is a mobile communication terminal in which a display unit such as a liquid crystal display (LCD) and a key input unit are formed on the same body, and the key input unit is protected or received by using a cover connected to the bottom by a hinge.

In the folder method, two folder parts can be opened and closed by hinges, and a main display unit and a key input unit are respectively formed on surfaces facing each other. The folder-type mobile communication terminal may close two folders to protect the display unit and the key input unit, and open a folder to receive a call or perform a desired function through key input.

Lastly, the sliding type mobile communication terminal is a mobile phone of the two sliding parts arranged to overlap each other, and the display unit and the key input unit facing the same direction on the sliding parts, respectively. In general, the sliding type mobile phone may expose the display unit or the key input unit that is covered by the rear side by sliding the front sliding part relatively.

1 is a perspective view of a conventional slide phone.

Referring to FIG. 1, the conventional slide phone 10 includes a main part 20 and a sliding part 30. The battery 22 is detachably mounted on the rear of the main part 20, a key input 24 is formed at the front lower end thereof, and an antenna 26 is provided at the upper end thereof.

The sliding part 30 is mounted on the front of the main part 20 to be slidable up and down. A large liquid crystal display (LCD) window 32, a menu key 34, a telephone, and the like are formed on the front of the sliding part 30. The sliding part 30 may be moved upward to expose a key input part hidden behind, and the call may be received or hanged up from another person through the movement.

Since the slide phone 10 is directly exposed to the front of the LCD window 32, the phone contents and other information can be read directly without moving the sliding part 30, and the menu key 34 can be used to read the phone phone. Other functions can be easily performed. In addition, since most of the front area of the sliding part 30 can be used as the LCD window 32, the LCD window 32 can be used widely.

In the conventional sliding phone, a slide track (not shown) is interposed between the main part 20 and the sliding part 30. The slide track 30 generally includes a guide rail, a fixed block and an elastic latch. The guide rail is fixed to the sliding part 30, and the fixing block is fixed to the main part 20. By moving up and down in the state in which the fixed block is accommodated in the guide rail, the sliding part 30 slides up and down on the main part 20.

However, since the fixed block and the guide rail function to open and close the slide phone, wear is largely generated by frequent friction. Therefore, it is usually manufactured using a metal plate having good wear resistance. At this time, in the case of using the press working, mainly stainless steel is used, while stainless steel (SUS) becomes magnetic during press working, and a short occurs, and a TDMA noise problem, which is a noise appearing at an audio output terminal during a telephone call, occurs.

In addition, in the process of producing the sliding track, each part manufactured has a certain error range, and the smaller the planned error range, the higher the manufacturing cost of the product. The sliding track connecting the main part 20 and the sliding part 30 requires a relatively high dimensional accuracy compared to other products, which is difficult to manufacture, and requires a complicated and difficult manufacturing process to increase the dimensional precision. Has the disadvantage of increasing.

In addition, when the sliding track is manufactured by injection molding, a plurality of hinge cases, rails, rail guides, and the like must be connected to each other. There is a problem that increases the thickness of.

Accordingly, an object of the present invention for overcoming the above-mentioned problems is to provide a mobile communication terminal using a sliding method having excellent mechanical characteristics while preventing TDMA noise generated during a call.

In addition, another object of the present invention is to provide a mobile communication terminal using a sliding method of improving the sliding operation feeling when opening and closing the mobile communication terminal.

In addition, another object of the present invention is to provide a mobile communication terminal using a sliding method to reduce the manufacturing cost by increasing the dimensional accuracy when manufacturing the mobile communication terminal.

In addition, another object of the present invention is to provide a mobile communication terminal using a sliding method with improved assembly productivity by simplifying the assembly structure.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, a mobile communication terminal using a sliding method is provided with a main part, a sliding part, a hinge part.

The main part is detachably mounted on the rear of the main part, a key input part is formed at the front lower part, and an antenna is provided at the upper part. A sliding part is mounted on the front of the main part to be slidable up and down. A large liquid crystal display (LCD) window, a menu key, a telephone, and the like are formed on the front of the sliding part. The sliding part may be moved upward to expose a key input part that is hidden behind, and through the movement, a call received from another person or a call may be hung up.

The hinge part includes a first hinge part and a second hinge part. The first hinge part is mounted between the main part and the sliding part, and the material may be manufactured to have nonmagnetic or relatively weak magnetic properties using aluminum, an aluminum alloy, or engineering plastics. However, since a material such as aluminum or plastic may have a relatively low hardness or low workability, it is preferable that the second hinge portion coupled with the first hinge portion and slidably move has a higher hardness than the first hinge portion. . Since the second hinge part is connected to the sliding part, a material having excellent strength and workability may be used. For example, the second hinge part may be formed using stainless steel or other materials having good hardness / processability.
For reference, engineering plastics refers to ordinary plastics that are used as industrial materials and structural materials because of excellent heat resistance, mechanical strength, abrasion resistance, and insulation.

In particular, the first hinge part manufactured by a conventional aluminum extrusion or aluminum casting molding method may have a weak magnetic property, and the first hinge part may be insulated by surface treatment by an anodizing method. In addition, since the surface of the first hinge portion has a high surface hardness by the anodizing method, the frictional surface is not worn or peeled off, so that the sliding feeling can be maintained luxuriously.

Since the first hinge portion and the second hinge portion are insulated from each other, the first hinge portion and the second hinge portion may be short-circuited to each other, thereby solving the TDMA noise problem, which is a noise appearing at the audio output terminal.

In addition, aluminum can easily obtain a multi-faceted shape in consideration of various processes with excellent systemic properties. Therefore, the first hinge unit can be manufactured using a conventional aluminum extrusion method, and since the specific gravity of aluminum is light, the weight of the mobile communication terminal can be reduced by lightening the load of the first hinge unit.

The conventional mobile communication terminal using the sliding method used a method of sliding the drive by forming a shape of the hinge part. Therefore, since the hinge part may have magnetism, a short occurs during a phone call, causing a TDMA noise problem. However, the mobile communication terminal using the sliding method of the present invention is manufactured by using a conventional aluminum extrusion molding method, the first hinge is manufactured in a desired shape while being insulated by anodizing treatment. Therefore, the short part does not occur in the hinge part, thereby solving the TDMA noise problem during a call. Similarly, the hinge parts may all be manufactured using conventional aluminum extrusion methods. In the present invention, the second hinge portion is manufactured using a press working method using a material having a relatively higher hardness than the first hinge portion. In addition, since the first hinge part can greatly improve the surface hardness by anodizing, the second hinge part can be reliably connected to the sliding part, and the strength and workability of the hinge part are excellent, and mechanical properties can be increased. have.

In addition, the mobile communication terminal using the sliding method according to the present invention, in forming the hinge part, the processing is easy, so that the dimensional accuracy can be increased to reduce the manufacturing cost. In addition, the surface is smoother than the hinge part manufactured by injection molding, and there is less friction generated when the sliding drive is performed. Accordingly, a smooth slide feeling can be obtained, and the inconvenience of the user can be eliminated.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

Can be. However, the sliding part 120 may have more various functions, and the functions may likewise be replaced with other functions. In the sliding opening and closing method, at the initial position where the main part 110 and the sliding part 120 are in contact with each other, the sliding part 120 may be moved upward during a phone call to expose a key input part that is hidden behind the moving part. You can also answer or end a call from someone.

The hinge part 130 includes a first hinge part 132 and a second hinge part 142. The first hinge portion 132 is connected to the upper portion of the main part 110 to help the sliding drive. Guide hinges 134 are formed at both sides of the first hinge portion 132, and the guide grooves 134 extend along the horizontal axis of the first hinge portion 132. The guide groove 134 is formed to face each other at the sides of the first hinge portion 132 in a c-shape so that the second hinge portion 142 slides up and down on the inner surface of the first hinge portion 132.

The second hinge part 142 is connected to the lower part of the sliding part 120 to help the sliding part 120 to slide up and down. In addition, the second hinge portion 142 includes a hinge plate 144 and a guide flange portion 146. The hinge plate 144 is positioned at the center of the second hinge portion 142 and connected to the inner surface of the sliding part 120. At both ends of the hinge plate 144, the B-shaped guide flanges 146 are positioned to face in opposite directions to each other and are connected through a bend line. The guide flange 146 is inserted into the guide groove 134 and slides in the direction in which the guide groove 134 guides.

The elastic member 150 is formed between the first hinge portion 132 and the second hinge portion 142, and connects the first hinge portion 132 and the second hinge portion 142 to each other to open and close the mobile communication terminal. Makes it semi-automatically possible. In the present invention, two elastic springs 152 are connected to each other, but in other embodiments, various types of elastic members 150 may be used to open and close the mobile communication terminal according to a designer's intention.

3 and 4, the hinge part 130 includes a first hinge part 132 and a second hinge part 142. The first hinge portion 132 and the second hinge portion 142 are connected to each other by the guide groove 134 and the guide flange portion 146. The second hinge portion 142 is slid up and down along the guide groove 134 (①), the mobile communication terminal is sliding opening and closing. The first hinge portion 132 is manufactured using an aluminum material. Here, aluminum is used in many fields because of its superiority. In the present invention, the first hinge portion 132 is manufactured by a conventional extrusion method using aluminum. Thereafter, the first hinge portion 132 is insulated by using an anodizing post-treatment method. Therefore, since the second hinge portion 142 is not shorted, the TDMA noise problem that occurs due to hardware characteristics can be solved. In addition, since the surface hardness of the first hinge portion 132 using the anodizing method is very high, the friction surface is not worn or peeled off, which is advantageous during sliding movement. In addition, since the process of the first hinge portion 132 uses a conventional extrusion molding method, it is possible to easily and accurately manufacture the shape of the first hinge portion 132, and the hinge part 130 manufactured only by the injection molding method. Since the surface is smooth, the sliding drive between the hinge parts 130 occurs smoothly. Therefore, it is possible to increase the purchasing power by making the user feel the sliding of the mobile communication terminal. In addition, a first hole 136a is formed on an inner surface of the first hinge portion 132 so that one end of the elastic member 150 is connected. The second hole 136b is formed at both sides thereof and is connected to the main part 110 with a screw. However, in another embodiment of the present invention, according to the designer's intention, the process of the first hinge portion may be manufactured using various methods such as conventional aluminum casting.
For reference, casting refers to a casting method in which a metal is melted and poured into a predetermined mold to be hardened. Aluminum casting refers to a casting made of aluminum.

In addition, a third hole 148 is formed at the side of the hinge plate 144, and the other end of the elastic member 150 is connected to the third hole 148. Therefore, the first hinge part 132 and the second hinge part 142 are semi-automatically driven by the elastic member 150 having elastic force. Semi-automatic means moving 50 percent stroke manually and the rest automatically by elastic force. The second hinge portion 142 is manufactured using a press working method. Both ends of the second hinge portion 142 are bent to face the hinge plate 144. At this time, the both ends are bent about 180 degrees to face each other, and bent in the opposite direction to the first bent along the bending line of the hinge plate 144 and the guide flange 146 (ⓐ), b-shaped It becomes the guide flange part 146 formed. Therefore, the second hinge portion 142 can be manufactured by bending one plate shape by using a press working method. Conventionally, the two plates are attached to each other, so that they are manufactured in various processes. However, the present invention may be omitted in the form of one plate.

The second hinge portion 142 uses a material having a greater hardness than the first hinge portion 132. Therefore, the second hinge portion 142 can be easily processed to increase the dimensional accuracy, and the mechanical properties such as hardness and strength of the second hinge portion are good, so that the structure can be stably maintained even at frequent opening and closing of the second hinge portion 142. I can keep it.
