Description

  The present invention relates to a cycloid hinge module, and more particularly, to a swivel type portable terminal, in which a second body formed with an image portion is compared with a first body combined therewith. When rotating, instead of simply rotating, the second body pushed upward is configured to be capable of a semi-automatic sliding operation downward, thereby reducing the size limit of the image portion. The present invention relates to a cycloid hinge module that can be supplemented, has a beautiful appearance, and is easy to operate.

  Industrial demand for portable terminals is increasing every year, and as a result, portable terminals having various forms and functions according to the demands of consumers have appeared. Ordinary portable terminals have an image part that displays video, graphics, etc., and many portable terminals that also have a function to allow watching TV through such an image part have appeared. is doing.

  In contrast to mobile terminals, especially mobile phones, which usually have an image part that is vertically long depending on the intended use, taking into account the ease of gripping by the user, Since it is formed to extend in the horizontal direction for the convenience of viewing, it is necessary to configure the portable terminal to be sideways in order to view a television or the like through the portable terminal. Considering these points, recently, it is separated into a part where the image part of the portable terminal is formed and another part connected to the part, so that it can be rotated by 90 ° The terminal which becomes has appeared newly. This is to prevent the user from having to rotate the terminal in order to arrange the image portion in the horizontal direction. A portable terminal that is configured to be rotatable instead of the fixed shape is generally referred to as a “swivel-type”.

  However, the swivel type portable terminal as described above has the following drawbacks. FIG. 1 shows such a conventional swivel portable terminal, which includes a body 2 provided with an image portion and a body 1 that rotatably supports the body 2. The body 2 must be formed such that the length from the central axis for rotation to any end of the edge is not longer than the length from the central axis to the vertical lower end. This is because when the body 2 is in the form of a normal quadrangle, there is a risk that the rotation will be caught by the jaw of the body 1 during rotation. Therefore, as shown in FIG. 1A, the lower end portion of the body 2 is rounded so that all the lengths to the end portion are the same with respect to the central axis. In this case, since the image portion formed on the body 2 is limited in size, a space is generated in the overall outer shape of the terminal, and the aesthetic appearance is impaired.

  FIG. 1B shows a swivel type portable terminal of another form, in which the length from the central axis to the vertical lower end of the body 2 is shortened from the beginning. In such a terminal, it is difficult to eliminate the drawbacks as shown in FIG. 1 (a), but there is a problem that the useless space becomes wider.

  In addition, even when the conventional terminal is rotated, the body 2 is positioned at the upper portion with respect to the entire terminal, so that the center of gravity is high, and the appearance is stable and beautiful. Could not be secured.

  The present invention is not limited by the shape and size of the image portion, can be applied to a swivel type portable terminal, and can be easily operated during rotation and can be operated semiautomatically. About.

  The present invention is used in a portable terminal having a first body and a second body that can rotate and slide relative to the first body, and is fixedly coupled to the first body and has a first link on the lower side. A fixed plate provided with a guide portion formed in a vertical direction on the upper side of the first link portion, slid along the longitudinal direction of the guide portion, fixedly coupled to the second body, and one side A floating plate provided with a second link portion, and one side rotatably coupled to the first link portion, the other side rotatably coupled to the second link portion, and the floating plate rotating relative to the fixed plate A cycloid hinge module including a link arm for sliding along a guide portion is provided.

  According to the present invention, first, the fixed plate coupled to the first body and the floating plate coupled to the second body are configured to be coupled to each other by the link arm, while the second body rotates. By making it slide, the restriction on the shape and size of the second body can be removed.

  Secondly, when the floating plate rotates, the hinge module can be operated easily and smoothly by configuring it so as to perform linear reciprocating motion.

  Thirdly, by configuring the elasticity generating portion that attempts to move the floating plate toward the first link portion, a semi-automatic operation is possible, and the operation is further facilitated.

The swivel portable terminal is not only a normal folding terminal but also a straight terminal and a sliding terminal. Etc. can be included as long as they require a swivel operation, and can be used for all terminals that need to be rotated in order to lengthen the image portion that is long in the vertical direction in the horizontal direction.

  The cycloid hinge module 1 of the present invention is used in a terminal configured by dividing a portable terminal into a first body 100 and a second body 200. The first body 100 is a body that supports rotation, and the second body 200 is configured to rotate with respect to the first body 100. As shown in FIG. 2, the foldable terminal forms a lid portion of the operation unit 300 (where the keypad is provided), and the portion that hinges with the operation unit 300 hits the first body 100. In the straight type terminal, the operation unit itself hits the first body 100.

  A state in which the image portion formed on the second body 200 is elongated in the vertical direction is a normal state, and in the present invention, this state is defined as an initial state for convenience of explanation. The state in which the second body 200 rotates from the initial state and can no longer rotate in the same direction is referred to as a final state.

  The fixing plate 10 is fixedly coupled to the first body 100. The fixed plate 10 has a thin plate shape as a whole, and is provided with the first link portion 11 on the lower side (the image portion of the normal portable terminal 500 is a front view downward direction). The guide unit 12 is provided on the upper side of the unit 11 (the image unit of the normal portable terminal 500 is viewed from the front).

  The first link part 11 is a part to which the link arm 30 is connected, and the guide part 12 guides the direction in which the idle plate 20 slides. The first link portion 11 is formed with a coupling portion so that the link arm 30 can rotate about the first link portion 11.

  The guide part 12 is formed straight above the first link part 11 in the vertical direction. Therefore, even if the floating plate 20 guided by the guide portion 12 rotates, the center thereof moves along the guide portion 12.

The length of the link arm that connects the first link portion 11 and the second link portion 21 is formed so as not to be shortened so as not to hinder the rotation and slide movement of the floating plate 20.

  Hereinafter, an operation in which the second body 200 rotates with respect to the first body 100 will be described in detail.

  Referring to FIG. 2, if the rotation operation is carefully examined, when the second body 200 rotates from the initial state and rotates clockwise, the floating plate 20 fixedly coupled to the second body 200 also rotates clockwise. Rotate to. At this time, the link arm 30 connected to the floating plate 20 rotates counterclockwise about the first link portion 11, and at the same time as the rotation, the link arm 30 moves to the floating plate 20. By pushing up upward, the floating plate 20 slides upward along the guide portion 12. Accordingly, in the portable terminal 500, the second body 200 is pushed upward even when the second body 200 rotates clockwise with respect to the first body 100 for swivel operation. 2 Even if the lower corner of the body 200 is not rounded, it will not be caught, and the shape of the second body 200 is not limited.

  When the second body 200 continues to rotate, the center of the floating plate 20 ascends along the guide portion 12, and there is a point where the floating plate 20 can no longer be raised. This point corresponds to a dead point. When the dead point is passed, the center of the floating plate 20 is lowered again, and when the floating plate 20 reaches the lower end of the guide portion 12, the rotation stops and the final state is reached. Accordingly, since the second body 200 to which the floating plate 20 is fixedly coupled can be positioned relatively below the first body 100, a stable structure can be provided and the appearance is extremely excellent. .

  FIG. 3 is an exploded perspective view of a cycloid hinge module according to another embodiment of the present invention. In the cycloid hinge module 1 according to a preferred embodiment of the present invention, the guide portion 12 passes through a central portion of the fixing plate 10. Thus, it has a long hole shape extending in the vertical direction.
