BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone, and more particularly, to a swing phone capable of operating a phone or opening and closing a key input unit by rotating two parts constituting the mobile phone from side to side.

As wireless communication technology develops, wireless communication technology is widely applied in various fields of products. Wireless communication technology is also applied to a telephone, and an example is a portable telephone capable of transmitting and receiving a sound signal wirelessly.

In general, the portable telephone may include a wireless transceiver included in a home wireless telephone, and may be used as a comprehensive concept including a mobile phone which is widely used in recent years.

Small phones are preferred because they are primarily intended for portability, and they tend to be extraordinary in design and include a variety of functions. Therefore, according to the trend of mobile phones released these days, externally small and thin products are continuously favored with respect to mobile phones, and light and excellent products are preferred. Also, internally, mobile phones including multifunctions are preferred.

Such mobile phones may be generally classified into a flip type, a folder type, a sliding type, and a swing type according to their appearance or operation.

The flip type mobile phone generally refers to a mobile phone of 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. .

A folder type mobile phone can be opened and closed by connecting two folder parts by a hinge, and means a mobile phone having a main display unit and a key input unit respectively formed on opposite sides thereof. Folder-type mobile phones can close two folders to protect the display and the key input unit, and open two folders up and down to receive a call or perform a desired function through key input.

The sliding cell phone refers to a cell phone in which two sliding parts are disposed to overlap each other, and the display part and the key input part face in the same direction on each sliding part. In general, the sliding type mobile phone may expose the display unit or the key input unit that is hidden on the rear side by sliding the front sliding part relatively.

Finally, the swing type mobile phone includes two swing parts, and like the sliding type mobile phone, the display part and the key input part are directed in the same direction to each swing part. However, it rotates left and right about the center axis perpendicular to the upper surface, and the front swing part is rotated about 180 degrees to expose the display unit or the key input unit hidden behind the rear surface.

Korean Unexamined Patent Publication No. 2000-0036958 discloses a "rotary folding portable converter." The rotatable folding cellular phone is an open / close direction that is opened and closed in a width direction instead of a length direction, and means the swing type mobile phone.

Swing-type mobile phones are exposed to the outside of the liquid crystal screen to facilitate time, function activation, caller display, etc., and even when the phone is closed, the liquid crystal is not impacted to extend the life of the product.

However, in the swing-type mobile phone disclosed, both hands must be used because the swing part must be directly rotated by about 180 degrees. In addition, since the swing part of the swing part is long, it is very difficult to open the swing phone with one hand and it is inconvenient because two hands must be used.

Accordingly, one object of the present invention to overcome the above problems is to provide a swing phone that can automatically open a swing part.

In addition, another object of the present invention is to provide a swing phone that moves the remaining angle by itself if the user pushes only a predetermined angle without pushing the sliding part to the end.

According to a preferred embodiment of the present invention for achieving the above object, a swing phone includes a main part, a swing part and an automatic hinge member.

The main part and the swing part are connected by the automatic hinge member, and the swing part is rotated on the main part about the central axis of the automatic hinge member. In general, the main part is equipped with key inputs, a microphone and a rechargeable battery, and the swing part is equipped with an LCD display window, a menu key and a call key.

In the call waiting state, the swing part and the main part overlap each other, and the key input part of the main part is hidden behind the swing part.However, when a call is received from the outside or when using other functions of the mobile phone, the swing part rotates to the microphone or Can be used with the key input exposed.

At this time, the automatic hinge member may automatically rotate the swing part by a user's manipulation or a program already set. Here, automatic means moving all or part of the movement of the swing part up to the desired final angle by operation other than the user. The swing part can be automatically rotated by an external signal input or an initial movement of the swing part.

Therefore, the swing part can be automatically moved to the desired final angle, and the user can comfortably solve the opening and closing problem that has become a problem.

The automatic hinge member may include a main fixing part fixed to the main part, a swing fixing part fixed to the swing part, and a driving device for rotating the swing part. The driving device and the swing fixing part may be connected by a gear train to connect the driving device. The rotation can be transferred to the swing fixture. That is, the swing part rotates about the main axis with respect to the main part by the rotation of the swing fixing part.

The swing part can be rotated without a force by the mechanical structure rather than the transmission.

For example, the automatic hinge member may include a main fixing part fixed to the main part, a swing fixing part fixed to the swing part, and a driving hinge part for rotating the swing part.

The drive hinge is mounted between the main fixture and the swing fixture, and when the swing fixture rotates by the drive angle already set with respect to the main fixture, it moves the remainder of the final desired angle by mechanical actuation, resulting in the rotation of the swing part. Let's do it. To this end, first and second hinge assemblies that are functionally connected to the swing fixture may be used, and the first and second hinge assemblies may provide a driving force for rotating the swing fixture by dividing the section from the driving angle to the final angle, respectively. Can be.

The second rotation inclined sphere 174 is integrally connected with the second gear 158 and rotates together, and is positioned at the inlet side of the second hinge case 172. The second fixed ramps 176 are in contact with the second rotary bevel 174 inwardly of the second hinge case 172, and the second hinge spring 178 is opposed to the second rotary bevel 174. The second fixed inclined sphere 176 is supported. Since the second hinge spring 178 pushes the second fixed inclined sphere 176 toward the second rotary inclined sphere 174, the inclined surface between the second fixed inclined sphere 176 and the second rotary inclined sphere 174 is Keep in touch at all times. In addition, a second guide 176G protrudes from the side surface of the second fixed inclined sphere 176, and the second guide 176G is coupled to the second hinge case 172 so that only linear motion is possible, so that the second fixed inclined sphere Limit the rotation of 176.

In addition, the inclined surfaces and the pass surfaces are formed in a trigonometric curve shape or similar naturally connected.

Hereinafter, a process of opening the swing part 110 according to an angle to explain the operation of the swing phone 100 according to the first embodiment will be described.

5A is a front view of the swing part rotated about 30 degrees and the automatic hinge member in the state, and FIG. 5B is a rear perspective view partially enlarged of the automatic hinge member of FIG. 5A. 5A and 5B illustrate a state before the swing part 110 passes a 45 degree driving angle.

5A and 5B, while the swing part 110 rotates about 30 degrees, the center gear portion 144 of the swing fixing portion 140 rotates about 30 degrees counterclockwise, and correspondingly, the first Gear 156 and second gear 158 rotate about 30 degrees clockwise. In this case, the center gear unit 144, the first gear 156, and the second gear 158 have the same diameter and the same number of teeth, mesh with each other, and rotate by the same angle.

As the first gear 156 rotates, the first rotational inclination hole 164 also rotates about 30 degrees. The first threshold passage surface 164T of the first rotary inclined sphere 164 is in close contact with the first threshold slope surface 166T of the first fixed inclined sphere 166 and exerts a force perpendicular to the circumferential direction. 1 is applied toward the fixed ramps 166. As a result, the first fixed inclined sphere 166 is retracted by the rotation of the first rotary inclined sphere 164, and the first hinge spring 168 is contracted by the retraction of the first fixed inclined sphere 166.

At the same time, the second gear 158 also rotates, and the second rotational inclination hole 174 also rotates about 30 degrees. In addition, the second threshold passage surface 174T of the second rotary inclined sphere 174 is in close contact with the second threshold sloped surface 176T of the second fixed inclined sphere 176 to apply a force in the circumferential direction and at the same time perpendicular thereto Is applied toward the second fixed ramp (176). As a result, the second fixed inclined sphere 176 is also retracted by the rotation of the second rotary inclined sphere 174, and the second hinge spring 178 is contracted by the retraction of the second fixed inclined sphere 176. .

6A is a front view of the swing part rotated about 45 degrees and the automatic hinge member in the state, and FIG. 6B is a rear perspective view partially enlarged of the automatic hinge member of FIG. 6A.

6A and 6B, while the swing part 110 rotates about 45 degrees, the first rotational inclination hole 164 also rotates about 45 degrees, and the vertex of the first rotational inclination hole 164 is fixed first. Passes through the vertex of the inclined sphere 166.

As the swing part 110 rotates by about 45 degrees or more, the contact portion of the first rotary inclined hole 164 is switched from the first threshold passage surface 164T to the first driving passage surface 164D, and the first driving is performed. The passage surface 164D is in contact with the first driving inclined surface 166D of the first fixed inclined sphere 166.

At this time, the first fixed inclined sphere 166 presses the first rotary inclined sphere 164 by the restoring force of the first hinge spring 168, and the first driving inclined surface 166D may be configured to move the first drive passage surface 164D. Push to rotate the first rotary inclined sphere 164 in the existing travel direction.

At the same time, if the second threshold passage surface 174T remains in contact with the second threshold slope surface 176T, the vertex of the second rotary slope sphere 174 passes through the second fixed slope sphere 176 through the vertex. It is in the previous state.

The elastic modulus of the first hinge spring 168 is greater than the elastic modulus of the second hinge spring 178, and the force applied to the first gear 156 by the first hinge spring 168 is the second hinge spring 178. ) Is greater than the force exerted on the second gear 158.

Therefore, even if the user rotates the swing part 110 to about 45 degrees or more and no longer applies a force to rotate the swing part 110, the force applied to the first rotational inclination hole 164 and the first gear 156 is relatively high. The cursor swing part 110 maintains the rotation direction by rotating in the existing rotation direction.

7A is a front view of the swing part rotated about 90 degrees and the automatic hinge member in the state, and FIG. 7B is a rear perspective view partially enlarged of the automatic hinge member of FIG. 7A.

7A and 7B, the first driving pass surface 164D of the first rotational inclination hole 164 passes through the first driving inclined surface 166D while the swing part 110 passes through an intermediate angle of about 90 degrees. The vertex of the first rotating bevel 164 is in contact with the first flat surface 166F of the first fixed bevel 166.

At the same time, the contact portion of the second rotary slope 174 is switched from the second threshold passage surface 174T to the second driving passage surface 174D, and the second driving passage surface 174D is the second fixed slope sphere (174D). In contact with the second driving inclined surface 176D of 176.

By the restoring force of the second hinge spring 178, the second fixed inclined sphere 176 presses the second rotary inclined sphere 174, and the second driving inclined surface 176D pushes the second driving passage surface 174D. The second rotary inclined sphere 174 is rotated in the existing traveling direction. At this time, since the flat surface and the vertices are in contact with each other between the first rotating inclined sphere 164 and the first fixed inclined sphere 166, relatively inferior force is applied to the second rotating inclined sphere 174 and the second gear. The rotation of 158 cannot be prevented.

As soon as the swing part 110 is located at a point of about 90 degrees, the inertia of the swing part 110 and the other parts causes the first rotating bevel 164 and the second rotating bevel 174 to move in the existing rotation direction. Proceed further by a small range of angles. At this time, the contact portion of the second rotary inclined sphere 174 is switched from the second threshold passage surface 174T to the second driving passage surface 174D, and the second gear 158 by the restoring force of the second hinge spring 178. ) And the swing part 110 continue to move in the existing rotational direction.

8A is a front view of the swing part rotated about 135 degrees and the automatic hinge member in the state, and FIG. 8B is a rear perspective view partially enlarged of the automatic hinge member in FIG. 8A. 8A and 8B illustrate a state in which the swing part 110 passes between an intermediate angle and a final angle.

8A and 8B, the swing part 110 abuts the second drive passage surface 174D and the second drive inclined surface 176D at about 135 degrees to transfer the force from the second hinge spring. And, the second rotation inclined sphere 174 is rotated in the existing rotation direction by the second fixed inclined sphere 176.

At this time, the second gear 158 by the second hinge rotation assembly 170 because the contact between the first rotating inclined sphere 164 and the first fixed inclined sphere 166 is provided only by the flat surface and the vertex and provide only mutual frictional force. And the rotation of the swing part 110 cannot be prevented.

In addition, the surface of the first rotary inclined sphere 164 and the first fixed inclined sphere 166 may be slippery surface treatment to have a small friction force, or both components may slide smoothly with a lubricant such as grease. .

9A is a front view of the swing part rotated about 180 degrees and the automatic hinge member in the state, and FIG. 9B is a rear perspective view partially enlarged of the automatic hinge member of FIG. 9A.

9A and 9B, when the swing part 110 rotates to a final angle of about 180 degrees, the first threshold pass surface 164T of the first rotation tilt hole 164 is different from the first threshold slope surface ( 166T, the vertex of the second rotary inclined sphere 174 is located between the second drive inclined surface 176D and the second threshold inclined surface 176T, and consequently the first gear 156, the second gear ( 158 and the rotation of the swing part 110 stop at about 180 degrees.

According to the above process, when the user rotates the swing part 110 to a driving angle of about 45 degrees, afterwards, the first hinge assembly 160 and the second hinge assembly 170 alternately act to swing the swing part 110. 110) automatically rotate up to about 180 degrees.

In order to close the swing phone 100, the swing part 110 may be rotated in the opposite direction to move to the original position. In addition, if the wire twist between the swing part 110 and the main part 120 is resolved, the swing part 110 is rotated about 45 degrees in the same direction as the open direction to automatically return the swing part 110 to its original position. It may be.

In this embodiment, the driving angle is about 45 degrees, the intermediate angle is about 90 degrees, and the final angle is about 180 degrees. However, the swing phone according to the present invention can set various driving angles, intermediate angles and final angles, and the threshold inclination surface and the driving inclination surface are formed symmetrically or asymmetrically to variously adjust the reference angles.

In the swing phone according to the third embodiment, the other components except for the first hinge assembly 160a are the same as the first hinge assembly 160, and the first fixed ramp 166a is disposed in the first hinge assembly 160a. By forming symmetry on both sides, the swing part can be opened automatically by rotating in either direction. Therefore, the description of the present embodiment may refer to the description and the drawings of the first embodiment, and the content overlapping with the description of the first embodiment may be omitted in the description of the present embodiment.

11, 12A, and 12B, the first hinge assembly 160a may include a first hinge case 162, a first rotating bevel 164, a first fixed bevel 166a, and a first hinge spring. 168.

The first fixed slope 166a has a first left threshold inclined surface 166T-L and a first left driving inclined surface 166D-L formed at intervals of about 45 degrees and 45 degrees, respectively, and are symmetrical thereto. 1 The right threshold slope 166T-R and the first drive slope 166D-R are formed at intervals of about 45 degrees and 45 degrees, respectively. The first flat surface 166F is formed at an interval of about 180 degrees between the first left driving inclined surface 166D-L and the first right driving inclined surface 166D-R.

The first hinge case 162 is located adjacent to the first gear 156 on the rear surface of the second main fixing housing 154. The first rotary inclined sphere 164 is integrally connected with the first gear 156, and the first fixed inclined sphere 166a is in contact with the first rotary inclined sphere 164 inward of the first hinge case 162. have. The first hinge spring 168 supports the first fixed inclined sphere 166a opposite to the first rotary inclined sphere 164.

The first rotary inclined hole 164 includes a first threshold passage surface 164T and a first driving passage surface 164D. When the first rotary inclined sphere 164 rotates in the counterclockwise direction as shown in FIG. 2, the first threshold passage surface 164T passes while pushing the first left threshold slope surface 166T-L, and the first left drive The first drive passage surface 164D is rotated by the inclined surface 166D-L. However, when the first rotational inclined sphere 164 rotates in the clockwise direction opposite to that in FIG. 2, the first driving passage surface 164D passes while pushing the first right threshold inclined surface 166T-R, and the first The first threshold passage surface 164T is rotated by the right driving inclined surface 166D-R.

The second hinge assembly 170, like the first embodiment, uses the second hinge case 172, the second rotary bevel 174, the second fixed bevel 176 and the second hinge spring 178. And, as described above, when the swing part rotates clockwise or counterclockwise, the swing part rotates from 180 degrees to 180 degrees, respectively, by more than 90 degrees.

Hereinafter, the operation of the automatic hinge member when the swing part rotates in the clockwise direction (opposite to the rotation direction of the swing part in FIG. 2) in the swing phone according to the third embodiment.

Referring to FIG. 12A, while the swing part 110 rotates about 30 degrees clockwise, the center gear portion 144 of the swing fixing part 140 rotates about 30 degrees clockwise, correspondingly to the first gear. 156 and second gear 158 rotate about 30 degrees counterclockwise.

As the first gear 156 rotates, the first rotational inclination hole 164 also rotates about 30 degrees. The first driving passage surface 164D of the first rotary inclined hole 164 is in close contact with the first right threshold inclined surface 166T-R of the first fixed inclined hole 166a and exerts a force in the circumferential direction and is perpendicular thereto. Force is applied toward the first fixed ramp 166. As a result, the first fixed inclined sphere 166a is retracted by the rotation of the first rotary inclined sphere 164, and the first hinge spring 168 is contracted by the retraction of the first fixed inclined sphere 166.

At the same time, while the second gear 158 also rotates and the second rotational inclined sphere 174 also rotates about 30 degrees, the second drive passage surface 174D is a second drive inclined surface of the second fixed inclined sphere 176. In close contact with 176D, a force in the circumferential direction is applied and a force perpendicular thereto is applied toward the second fixed inclined sphere 176a. As a result, the second fixed inclined sphere 176 is also retracted by the rotation of the second rotary inclined sphere 174, and the second hinge spring 178 is contracted by the retraction of the second fixed inclined sphere 176. .

Referring to FIG. 12B, while the swing part 110 rotates about 45 degrees clockwise, the first rotational inclination hole 164 also rotates about 45 degrees, and the vertex of the first rotational inclination hole 164 is fixed first. It passes through the vertex of the inclined sphere 166a.

As the swing part 110 rotates by about 45 degrees or more, the contact portion of the first rotational inclination hole 164 is switched from the first drive passage surface 164D to the first threshold passage surface 164T, and the first threshold The passage surface 164T is in contact with the first driving inclined surface 166D of the first fixed inclined sphere 166a.

At this time, the first fixed inclined sphere 166 presses the first rotary inclined sphere 164 by the restoring force of the first hinge spring 168, and the first driving inclined surface 166D may be configured to move the first drive passage surface 164D. Push to rotate the first rotary inclined sphere 164 in the existing travel direction.

At the same time, if the second threshold passage surface 174T remains in contact with the second threshold slope surface 176T, the vertex of the second rotary slope sphere 174 passes through the second fixed slope sphere 176 through the vertex. It is in the previous state.

The elastic modulus of the first hinge spring 168 is greater than the elastic modulus of the second hinge spring 178, and the force applied to the first gear 156 by the first hinge spring 168 is the second hinge spring 178. ) Is greater than the force exerted on the second gear 158.

Therefore, even if the user rotates the swing part 110 to about 45 degrees or more and no longer applies a force to rotate the swing part 110, the force applied to the first rotational inclination hole 164 and the first gear 156 is relatively high. The cursor swing part 110 rotates in a clockwise rotational direction to maintain the rotational direction.

Swing phone according to the present invention can automatically open or close the swing part is convenient to use, can quickly make or receive a call.

In addition, when the automatic hinge member of the mechanical structure is used, the swing part can be opened and closed with no power, so that the battery and other energy can be efficiently used.

In addition, by symmetrically forming the structure of the first fixed inclined sphere, the first hinge assembly can provide a driving force capable of rotating the switch part to an intermediate angle even after the driving angle in any direction.

As described above, while having been described with reference to the preferred embodiment of the present invention, those skilled in the art various modifications and changes within the scope of the present invention without departing from the spirit and scope of the present invention described in the claims below. It will be appreciated that it can be changed.
