Mobile terminal device
A mobile terminal device including a first housing, a second housing and a hinge foldably connecting the first housing and the second housing is provided. The mobile terminal device includes a hinge including a hinge mechanism which rotatably connects the first housing and the second housing. The device includes a flexible joint which liquid-tightly connects the first housing and the second housing and liquid-tightly contains the hinge mechanism.
1. A mobile terminal device including a first housing, a second housing and a hinge foldably connecting the first housing and the second housing, the mobile terminal device comprising:
the hinge comprising:
a hinge mechanism which rotatably connects the first housing and the second housing; and
a flexible joint which liquid-tightly connects the first housing and the second housing and liquid-tightly contains the hinge mechanism, the flexible joint being made of rubber,
wherein the hinge mechanism further includes:
a first fixed member that is fixed to the first housing;
a joint member including a first bearing formed at one end of the joint member and bearingly supported by the first fixed member; and
a tilt mechanism that is adjustable for a fold angle between the first housing and the second housing,
wherein the tilt mechanism includes:
a first ball member that is disposed in the first fixed member and is relatively rolled on the first bearing; and
one or more first recesses which are formed on outer circumference positions of the first bearing and control rotation of the first housing and the second housing by being engaged with the first ball member.
2. The mobile terminal device according to claim 1 , wherein:
the hinge mechanism further includes a second fixed member that is fixed to the second housing; and
the joint member further includes a second bearing formed at the other end of the joint member and bearingly supported by the second fixed member.
3. The mobile terminal device according to claim 2 , wherein the hinge mechanism further includes:
a tubular-shaped member that is disposed between the first fixed member and the second fixed member and through which a connecting member connecting the first housing and the second housing can be inserted.
4. The mobile terminal device according to claim 1 ,
wherein the hinge mechanism further includes:
a second fixed member that is fixed to the second housing; and
a joint member including a second bearing formed at the other end of the joint member and bearingly supported by the second fixed member;
wherein the tilt mechanism includes:
a second ball member that is disposed in the second fixed member and is relatively rolled on the second bearing; and
one or more second recesses which are formed on an outer circumference positions of the second bearing and control rotation of the first housing and the second housing by being engaged with the second ball member.
5. A mobile terminal device comprising:
a first housing;
a second housing; and
a hinge connecting the first housing and the second housing, the hinge including:
a hinge mechanism which rotatably, connects the first housing and the second housing; and
a flexible joint which liquid-tightly connects the first housing and the second housing and liquid-tightly contains the hinge mechanism, the flexible joint being made of rubber,
wherein the hinge mechanism further includes:
a first fixed member that is fixed to the first housing;
a joint member including a first bearing formed at one end of the joint member and bearingly supported by the first fixed member; and
a tilt mechanism that is adjustable for a fold angle and between the first housing and the second housing,
wherein the tilt mechanism includes
a first ball member that is disposed in the first fixed member and is relatively rolled on the first bearing; and
one or more first recesses which are formed on outer circumference positions of the first bearing and control rotation of the first housing and the second housing by being engaged with the first ball member.
