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 wireless telephone 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 constantly being released, and lightweight and excellent design products are preferred.

In general, mobile communication terminals may be classified into a flip type, a folder type, a sliding type, and the like 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 can close two folders to protect the display unit and the key input unit, and can 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 unit 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 widely used.

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 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, the slide track of a conventional sliding phone is mainly manufactured by injection molding, in which a plastic resin is melted and injected into a mold of a mold, and then solidified after a predetermined time and manufactured into a mold. Therefore, since the plastic resin is used as the main raw material, wear occurs due to frequent use, and there is a disadvantage that it is easily broken by an impact. Therefore, in the case of the slide track wear and tear frequently open and close, there is a risk that the structure is broken by the impact because the connection part of the main part 10 and the sliding part 20.

In addition, in the case of a mobile communication terminal using a conventional sliding method to compensate for these disadvantages, the hinge part is made of a metal material such as stainless steel (SUS), and is often manufactured using press working. The hinge part made of metal material is excellent in abrasion resistance, and is not loosened by frequent abrasion and is also strong in impact. However, in practice, the sliding stainless steel (SUS) causes a problem in the occurrence of noise during the call. In addition, since the sliding contact while sliding between the metal during the sliding drive, the feeling is transmitted to the user, there is a disadvantage that the sliding feeling that the user feels is not smooth.

In addition, in the process of producing the hinge part, each part to be manufactured has a certain error range, 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.

Accordingly, an object of the present invention for overcoming the above-mentioned problems is to provide a mobile communication terminal using a sliding method to improve the operation feel by smoothly driving the hinge while increasing the productivity of the hinge part.

Another object of the present invention is to provide a mobile communication terminal using a sliding method that can prevent the noise problem occurring during a call.

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.

It is still another object of the present invention to provide a mobile communication terminal using a sliding method that moves the remaining distance by itself by pushing only a predetermined distance without pushing the sliding part to the end.

According to a preferred embodiment of the present invention for achieving the above objects of the present invention, a mobile communication terminal using a sliding method includes a main part, a sliding part, a hinge part and a lubrication coating 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. The sliding part is mounted to the front of the main part so that the sliding part can slide 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. However, according to another embodiment of the present invention, the functions of the display (LCD) window, the menu key, and the talker may be mounted on the main part, and the battery part, the key input part, and the antenna may be mounted on the sliding part according to the designer's intention.

The hinge part includes a first hinge part and a second hinge part. At least one of the first hinge portion and the second hinge portion is disposed between the main part and the sliding part and mounted to the main part. And, at least one of the first hinge portion and the second hinge portion may be made of a fiber reinforced plastic material. Fiber-reinforced plastic refers to a plastic having improved mechanical strength, heat resistance, and impact resistance by using a reinforcement material combining nylon fibers and glass fibers, or using a reinforcement material combining polycarbonate and glass fibers. However, in other embodiments of the present invention, various reinforcing materials such as oriented nylon fibers may be used. As the molding method, an injection molding method is used. Therefore, if the first hinge portion is manufactured by the above method, the shape of the first hinge portion can be manufactured precisely and neatly, productivity can be increased, automation can be made, and mass production can be obtained, and economical advantages can be greatly obtained. The mechanical properties and impact resistance are strong to compensate for the problems of plastic material.

The other one of the first hinge portion and the second hinge portion may be formed of a press sheet metal such as stainless steel (SUS). Therefore, the press sheet metal is bent into a desired shape by using press working. However, in another embodiment of the present invention, both the first hinge portion and the second hinge portion may be manufactured using fiber reinforced plastic according to a designer's intention.

The lubricating coating is coated on the surfaces of the first hinge portion and the second hinge portion, respectively. Therefore, the first hinge portion and the second hinge portion can be driven smoothly when the sliding drive, the user can feel a sense of luxury slide. The material of the lubrication coating part is made of TEFLON paint, fluorine paint coating or acetal resin which has good abrasion resistance and excellent lubricity. In addition, the present invention has the advantage that the contact portion is not worn in comparison with the conventional wear caused by the frequent sliding drive material. However, in another embodiment of the present invention can be used using a variety of materials excellent in lubricity. Therefore, the surface of the first hinge portion produced by injection molding can be made not smooth. Thus, the surface of the first hinge portion is coated using a lubricating coating. The surface of the second hinge portion is also coated to reduce the friction between the portions where the two portions contact each other. However, in another embodiment of the present invention, only one of the first hinge portion and the second hinge portion may be coated according to the designer's intention.

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.

Example 1

2 is an exploded perspective view for explaining a mobile communication terminal using a sliding method according to the first embodiment of the present invention, Figure 3 is a sliding drive of the mobile communication terminal using a sliding method according to the first embodiment of the present invention. It is a perspective view for demonstrating.

2 and 3, the mobile communication terminal using the sliding method includes a main part 110, a sliding part 120, a hinge part 130, a lubrication coating part 150, and an elastic member 160. .

The main part 110 is located under the first hinge part 132, and the battery 112 is detachably mounted on the rear surface of the main part 110, and the key input part 114 is formed at the front lower part of the main part 110. At the top is provided an antenna 116. However, in another embodiment of the present invention, various functions, such as MP3 player, may be built in, or the functions may be replaced with other functions, according to a designer's intention.

The sliding part 120 is positioned above the main part 110, and a large liquid crystal display (LCD) window 122, a menu key 124, a communication device 126, and the like are formed in front of the sliding part 120. have. The sliding part 120 may have various functions such as MP3, and likewise, the functions may be replaced with other functions. In the sliding 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 hidden behind, and the movement may be performed. You can answer a call from another person or hang up.

The hinge part 130 is mounted between the main part 110 and the sliding part 120 and includes a first hinge part 132 and a second hinge part 142. The first hinge part 132 is positioned on the front surface of the main part 110, and guide grooves 134 are formed along the longitudinal direction at both sides. The guide groove 134 has a substantially c-shape and is positioned in directions in which the guide grooves 134 face each other on both sides of the first hinge portion 132. Therefore, the second hinge part 142 is in close contact with the inside of the first hinge part 132 to perform a sliding drive. A connection part 136 connected to the main part 110 is formed outside the guide groove 134 to strongly bind the main part 110. A first hole 137 through which the elastic member 160 penetrates is formed in the first hinge 132. The second hinge part 142 is located at the rear of the sliding part 120, and a hinge plate 144 is provided at the center part. The side of the hinge plate 144 includes a guide flange portion 146 connected via a bend line. Guide flange portion 146 is formed in a substantially b-shaped on both sides so that both ends protrude outward. Therefore, the protruding portion is inserted corresponding to the guide groove 134 to drive sliding along the guide groove 134.

The lubrication coating part 150 has a lubricating function by coating a lubricating paint on the surface of the hinge part 130. Therefore, the lubrication coating part 150 may be coated on the surfaces of the first hinge part 132 and the second hinge part 142 as a whole, or may contact only between the first hinge part 132 and the second hinge part 142. Can be coated. And, depending on the intention of the designer may be coated only on one surface of the first hinge portion 132 or the second hinge portion 142. Since the mobile communication terminal using the sliding method must be frequently opened and closed in order to use the function, the hinge part 130 is likely to be worn. Accordingly, the lubrication coating unit 150 may prevent wear occurring in the hinge part 130 by using a material having wear resistance together with a lubrication function. Therefore, the hinge part 130 is not loosened even after frequent opening and closing, so that the sliding drive as in the initial state can be maintained.

The elastic member 160 includes a first torsion spring 162 and a second torsion spring 164. The first torsion spring 162 and the second torsion spring 164 may be interposed between the first hinge portion 132 and the second hinge portion 142 to form the first and second hinge portions based on a predetermined turning point ( 132 and 142 provide repulsive force in different directions, respectively. Therefore, the first torsion spring 162 and the second torsion spring 164 are located side by side in the opening and closing direction to help the opening and closing of the mobile communication terminal. The first torsion spring 162 includes a circular portion 166, a fixing portion 168 and a binding screw 169. The circular portion 166 is formed at one end of the first torsion spring 162 and is located on the inner surface of the first hinge portion 132 and connected by the binding screw 169. The fixing part 168 is formed at the other end of the first torsion spring 162 and is connected to the second hinge part 142. Therefore, the fixing part 168 is fixed to the second hinge portion 142 does not move. Therefore, when the first hinge portion 132 moves in one direction, the fixing portion 168 is fixed to the second hinge portion 142 to prevent separation between the first hinge portion 132 and the second hinge portion 142. After the turning point, an elastic force is applied to open and close automatically. The binding screw 169 is attached to the inner surface of the first hinge portion 132 and fixes the circular portion 166, and the circular portion 166 is idling along the centrifugal force of the binding screw 169 so that the first torsion spring ( 162 to assist in changing the position. The second torsion spring 164 is formed in the same manner as the first torsion spring 162.

In the sliding drive, the guide flange 146 is initially inserted into the guide groove 134 and is primarily connected. And, the second hinge portion 132 and the second hinge portion 142 by the elastic member located between the second connection. Therefore, the second hinge portion 142 is fixed in the other direction, and can move along the longitudinal direction moving from the top to the bottom or the top to the bottom along the guide groove 134 (㉠). Sliding drive occurs through this movement, and can be used to open and close a mobile communication terminal using a sliding method.

Referring to FIG. 4, the material of the first hinge part 132 may be made of fiber reinforced plastic using nylon fiber and glass fiber as a reinforcing material, or fiber reinforced plastic using polycarbonate and glass fiber as reinforcing material. Injection molding is used as the molding method. Conventionally, when manufacturing a hinge part, since a plastic is usually used, there are many problems in using the hinge part because it is weak in mechanical properties and impact. However, the present invention can solve the above problems of the plastic by using a fiber reinforced plastic. Fiber-reinforced plastics are used as structural materials because they have high tensile strength, excellent impact resistance and good heat resistance. Therefore, the first hinge portion 132 may be manufactured in a difficult shape by using an injection molding process, and there is an advantage in that the productivity of parts is high and the automation is possible for mass production. However, in another embodiment of the present invention, fiber reinforced plastics in which other reinforcing materials are combined may be used.

In addition, connecting portions 136 are inserted into both side portions of the first hinge portion 132 to be connected to the main part 110. The connection part 136 is made of a metal material, and the main part 110 and the screw fastening so as to strengthen the binding force to be connected stably. The connection part 136 may be inserted at the time of injection molding or after pressure molding. In addition, a lubrication coating part 140 is coated on the surface of the first hinge part 132. The lubrication coating part 150 adds a lubrication function to the first hinge part 132 to help feel the sliding feeling smoothly. And the material of the lubrication coating unit 150 is mainly used for abrasion resistance and excellent lubricity Teflon (TEFLON) paint, fluorine paint coating or acetal resin.

5 is a perspective view illustrating a second hinge portion of a mobile communication terminal using a sliding method according to a first embodiment of the present invention, and FIG. 6 is a second hinge of the mobile communication terminal using a sliding method according to a first embodiment. It is sectional drawing for demonstrating addition bending.

5 and 6, the second hinge portion 142 is manufactured in one plate shape. Therefore, conventionally, the press working method which bends one plate shape of two plate shapes, adheres two plate shapes, and makes guide grooves in both side ends is used. However, the present invention can reduce the number of manufacturing processes, such as cutting and attaching because bending the plate shape to make the guide flange portion instead of the guide groove. The second hinge portion 142 includes a hinge plate 144 and a guide flange portion 146. Both ends of the hinge plate 144 form guide flanges 146 integrally connected. In addition, third sides 148 connected to the sliding part 120 are formed at both side portions of the hinge plate 144. In addition, a second hole 149 to which the other end of the elastic member 160 is connected is formed. Guide flange portion 146 is bent so that the end is parallel to the inner surface of the hinge plate (144). Then, when bent again by about 180 degrees or more in the opposite direction, the guide flange portion 146 formed in a b-shape protrudes outward (ⓐ). Similar to the first hinge portion 132, the second hinge portion 142 is coated with a lubricating coating portion 150, which is a lubricating paint. Therefore, the first hinge portion 132 and the second hinge portion 142 may be smoothly slides while reducing the friction between the parts in contact with each other, it is possible to manufacture a hinge part that is also resistant to wear. However, in another embodiment of the present invention, according to the designer's intention, the second hinge portion may also be manufactured using fiber reinforced plastic.

7 is a perspective view illustrating an operation principle of an elastic member of a mobile communication terminal using a sliding method according to a first embodiment of the present invention, and FIG. 8 is an elasticity of the mobile communication terminal using a sliding method according to a first embodiment. It is a side view for demonstrating a member.

7 and 8, the circular portion 166 of the first torsion spring 162 is connected to the upper end of the first hinge portion 132, and the fixing portion 168 is connected to the second hinge portion 142. It is fixed to the side. The circular portion 166 of the second torsion spring 164 is connected to the lower end of the first hinge portion 132, and is also fixed to the side of the second hinge portion 142 (①). Therefore, when the mobile communication terminal using the sliding method moves from the bottom to the upper direction, the sliding parts move from the initial state toward the turning point, and both ends of the first and second torsion springs 164 are bent so that their positions are close to each other. (②). At this time, if the mobile communication terminal using the sliding method is further raised upward, it passes through the maximum deformation point, and both ends of the first and second torsion springs 162 and 164 are repulsed in a direction away from each other and push against each other in the direction of travel. Even if the first and second torsion springs (162, 164) are automatically opened by the repulsive force itself.

In addition, since the present invention uses a nonmagnetic material, it is possible to prevent a noise problem by solving a problem of occurrence of a noise during a call. In addition, since the hinge part 130 is light in weight, the weight of the mobile communication terminal using the sliding method may be relatively lighter than that of the conventional mobile communication terminal. Therefore, it is more convenient for a user to carry, and thus it is suitable for performing a function as a mobile communication terminal.

The hinge plate 234 is formed at the center portion, and the guide flange portion 236 is connected to both sides of the hinge plate 234 via a bent line. The guide flange portion 236 is formed to protrude inward to both sides of the hinge plate 234 through two bendings. The first hole 238 is formed in the central portion of the hinge plate 234 to connect the elastic member. The material of the first hinge portion 232 uses a press plate such as stainless steel, and the processing method is bent into a desired shape using press working. The second hinge portion 242 provides guide grooves 244 at both ends. Guide grooves 244 formed in a substantially c-shape are positioned with the insertion hole of the groove toward each other outward. The second hinge portion 242 may be formed of fiber reinforced plastic using nylon fiber and glass fiber as a reinforcement material, or other injection molded plastic using polycarbonate and glass fiber as a reinforcement material. Uses injection molding. Therefore, the difficult shape like this invention can also be manufactured easily.
