The mobile terminal in accordance with the present invention may include a first body 10 provided with a display 12 for displaying information, a second body 20 slidably connected to the first body 10 and provided for mounting an input device 22 for inputting information and a battery 24 for supplying power, and a slide module 30 installed at the first body 10 and the second body 20 for guiding the first body 10 to slide relative to the second body 20.
A speaker 14 outputting sound may be installed at the first body 10, and a microphone 26 for inputting sound may be installed at the second body 20.
The slide module 30 may include a first slide member 32 fixed at a lower surface of the first body 10, a second slide member 34 slidably mounted to the first slide member 32 and fixed at an upper surface of the second body 20, and an elastic force unit 36 installed between the first slide member 32 and the second slide member 34. The elastic force unit 36 provides an elastic force movement when the first slide member 32 is slid upwardly or downwardly, allowing the first slide member 32 to be automatically slid.
The first slide member 32 formed in a plate shape may be coupled to the lower surface of the first body 10 by a bolt and provided with a guide rail 38 at both edges. The second slide member 34 formed in the plate shape may be coupled to the upper surface of the second body 20 by the bolt and provided with a guide groove 40 in which a guide rail 38 is inserted to be slid along the guide rail 38.
As illustrated in
The support member 50 may include a first rail groove portion 60 slidably supporting the first rod 52, a second rail groove portion 62 disposed in parallel with the first rail groove portion 60 and slidably supporting the second rod 54, a first elastic member mounting portion 64 extended from the lateral surface of the first rail groove 60 for fixing one end of the first elastic member 56, and a second elastic member mounting portion 66 extended from the lateral surface of the second rail groove 62 for fixing one end of the second elastic member 58.
Stopping jaws 70 prevent the first rod 52 and the second rod 54 from being separated, and may be inwardly protruded at the first rail groove portion 60 and the second rail groove portion 62. When the first rail groove portion 60 is provided at a front surface of the support member 50, the second rail groove portion 62 may be provided at a rear surface of the support member 50. Specifically, the first rail groove portion 60 may be provided at one surface and the second rail groove portion 62 may be provided at the other surface of the support member 50 for reinforcement, thereby preventing the support member 50 from being distorted.
A guide rail portion 72 may be configured with a step formed at both edges of the first rod 52 to be slidably stopped by the stopping jaw 70 provided at the first rail groove portion 60. A hinge hole 74 rotatably supported by a hinge pin 42 at the first slide member 32 (see
A third elastic member mounting portion 78, configured for attaching three elastic members, may be provided as an extension from the stopper portion 76 in a width direction for mounting the other end of the first elastic member 56. Those skilled in the are will appreciate that the elastic member mounting portion 78 is not limited to three elastic members.
The second rod 54 may also be provided with a guide rail portion 72 formed with a step at both edges of the second rod 54 to be slidably stopped by the stopping jaw 70, and have one end provided with a hinge hole 82 rotatably mounted at the second slide member 34 by a hinge pin 44 (see
A fourth elastic member mounting portion 86 may be formed as an extension from the stopper portion 84 in the width direction for mounting the other end of the second elastic member 58.
Preferably, the elastic members 56 and 58 may be formed of tension coil springs having one end respectively fixed at the elastic member mounting portions 64 and 66, provided at the support member 50, and the other end respectively fixed at the elastic member mounting portions 78 and 86 provided at the first rod 52 and the second rod 54.
As illustrated in
When both ends of the coil springs 56 and 58 are inserted into the insertion recesses 90, respectively, the diameter reduction portion 94 formed at both ends of the elastic members 56 and 58 may be inserted into the stopping portion 92. Accordingly, both ends of the elastic members 56 and 58 may be fixed at the support member 50 and the rods 52 and 54, respectively.
In another embodiment, as illustrated in
In the elastic member mounting portions 64, 66, 78, and 86, in accordance with another embodiment of the present invention, the connection pins 96 formed at the support member 50 and the first and second rods 52 and 54 may be wound with the connection rings 98 provided at ends of the elastic members 56 and 58. Accordingly, both ends of the elastic members 56 and 58 may be rotatably supported.
As illustrated in
As described above, when the first body 10 is closed with respect to the second body 20, the elastic members 56 and 58 connected between the support member 50 and the first and second rods 52 and 54, respectively may be compressed so that no elastic force is generated.
When the first body 10 is slid in an opened direction, the first slide member 32 is slid upwardly. Then, as illustrated in
As the first slide member 32 is further slid upwardly and passes a dead point, the elastic force from the elastic members 56 and 58 is exerted onto the first rod 52 and the second rod 54, accordingly the first slide member 32 may automatically be slid in the opened direction.
Once the first slide member 32 is slid upwardly to a fully opened position, as illustrated in
In the mobile terminal having the slide module in accordance with the present invention and having the configuration and operation as described above, the first rod 52 connected to the first slide member 32 by a hinge pin 42 and the second rod 54 connected to the second slide member 34 by a hinge pin 44 are slidably supported by the support member 50, respectively. The elastic members 56 and 58 are connected between the support member 50 and the first rod 52, and between the support member 50 and the second rod 54. Thus, the slide module is capable of enhancing durability and reliability of the mobile terminal.
