In various embodiments, the present invention relates to a slide actuator having a magnet and for opening and closing a portable terminal. Although an embodiment of the present invention is described with reference to a mobile phone, the present invention is not limited to the embodiment disclosed herein. It may be used in any suitable type of portable terminal, such as LCD displays, monitors, pagers, and the like.

6A and 6B illustrate a slide actuator (eg, actuator 100 (see FIGS. 2A, 2B, and 3), actuator 200 (see FIGS. 4A, 4B, and 5), etc.) according to an embodiment of the present invention. An example of a portable terminal 1 that may include a is shown. 6A and 6B, the terminal 1 is a mobile phone having not only the display screen 14 but also various buttons and electronic components (not shown). The body parts 51 and 52 of the terminal 1 are slidably coupled (eg, the body part 52 is slidable up and down with respect to the body part 51) to open and close the terminal 1. Track systems (eg, male and female track systems, etc.) may be provided to couple the body portions 51 and 52 and to achieve smooth movement between the body portions 51 and 52. Various systems can be used that can slidably couple the body portions 51 and 52 within the scope of the present invention. The portable terminal may include a slider body formed of an integral part of the main body part, and a slider body formed separately and coupled to the main body.

In various embodiments, the slide actuator is formed to slide between the body parts 51 and 52 of the terminal 1 to bias the body parts 51 and 52 to an open position or a closed position (described further below). In FIG. 6A, the terminal 1 is in an open position where the body part 52 slides upward with respect to the body part 51 to expose, for example, the lower part 60 (eg, keypad) of the body part 51. In FIG. 6B, the terminal 1 is in the closed position in which the body part 52 slides downward with respect to the body part 51 to cover the lower part of the body part 51, for example. As used herein, the term "body part" generally refers to a sliding portion or a non-moving portion of the terminal when the user opens and closes the mobile communication terminal. Therefore, the specific manner or other form that the user selects to open and close the portable communication terminal should not be considered as limiting the scope of the present invention.

2A and 2B illustrate an exemplary slide actuator 100 that may be used in a portable terminal according to one embodiment of the present invention. 2A shows one arrangement in which the slide actuator 100 is actuated when the terminal is reaching the first or closed position or is reaching the second or open position. 2B shows one arrangement in which the slide actuator 100 is operated when the terminal is in an intermediate or neutral position (or tipping point) (described further below) between the open and closed positions. do. The actuator 100 has a housing 105 that can be disposed between the sliding body portions (eg, body portions 51, 52, etc. shown in FIG. 6) of the portable terminal. A part of the actuator 100 is rotatably connected to one of the body parts 51 and 52 of the portable terminal by a connector, for example, a rivet 131 or the like. The other part of the actuator 100 is rotatably connected to the other of the body parts 51 and 52 of the portable terminal by another connector, such as a rivet 132 or the like. In other embodiments, the actuator 100 may have other means for rotatably coupling the actuator to the portable terminal instead of the rivet.

With continued reference to FIGS. 2A and 2B, magnets are retained in the housing 105. The magnets are aligned and held in some form. 2A and 2B, the letters N and S side by side represent the N and S poles of the magnet, respectively. The magnets include a plurality of stator or stationary magnets fixedly disposed in the housing 105. For example, the stator magnet 111 is disposed at one end of the housing 105. Another stator magnet 112 is disposed approximately in the center of the housing 105. The third stator magnet 113 is disposed at the other end of the housing 105. The polarities of the magnets 111, 112 are arranged such that the magnets 111, 112 repel each other. The magnets 112 and 113 also repel each other.

In addition, the housing 105 is provided with at least one moving magnet. The moving magnet may be connected to a corresponding connector, such as rivet 131 or rivet 132. When the housing is rotated between the body parts 51 and 52 of the mobile terminal, the moving magnet is movable between two mutually rebounding magnets in the housing 105. For example, in the embodiment shown in FIGS. 2A and 2B, the moving magnet 121 is installed in the housing 105 and is movable along the housing 105 between the stationary magnets 111 and 112. Another moving magnet 122 is installed in the housing 105 and is movable along the housing 105 between the stator magnets 112 and 113. The rivet 131 is coupled to the movable magnet 121 and is movable together with the movable magnet 121. The rivet 132 is coupled to the other movable magnet 122 and is movable together with the movable magnet 122. The number and arrangement of stator or movable magnets in the actuator housing may vary from one embodiment to another depending on factors such as terminal shape, relative spacing of connectors, magnet strength, magnet polarity, magnet size, and the like.

The polarities of the movable magnet 121 and the stator magnet 111 are arranged to attract the magnets 121 and 111 to each other. On the other hand, the movable magnet 121 and the stationary magnet 112 is arranged to repel each other. Similarly, the polarity of the moving magnet 122 is arranged in accordance with the polarity of the stator magnet 113 so that the magnets 122 and 113 attract each other. On the other hand, the movable magnet 122 and the stationary magnet 112 is arranged to repel each other. In this embodiment, the center stationary magnet 112 exhibits a magnetic force greater than that of other magnets, thereby improving the tendency to move the moving magnets 121 and 122 toward the stationary magnets 111 and 113.

Exemplary operation of the slide actuator 100 will be described with reference to FIGS. 2A, 2B, and 3. In this embodiment, when the actuator 100 is slidably moved between the terminal body portions 51, 52, the actuator 100 passes through the positions shown in FIG. 3. In FIG. 3, the positions in which the actuator 100 is tilted downward or upward correspond to the closed position and the open position of the mobile terminal 1. When the terminal is opening from the closed position or closed from the open position, the actuator 100 moves past the intermediate position shown horizontally in FIG. 3.

For example, when the terminal 1 is closed, the actuator 100 is located in the downwardly inclined position shown in FIG. The moving magnet 121 is located near the stator magnet 111, and the moving magnet 122 is located near the stator magnet 113 (see FIG. 2A). When the user of the terminal 1 slides one of the terminal body parts 51 and 52 with respect to the other of the body parts to open the terminal, the slide actuator 100 is moved from the downwardly inclined position toward the intermediate position. Specifically, the rivet 131 connected to one of the terminal body parts 51 and 52 and connected to the moving magnet 121 has the stator magnet 111 at the end of the housing 105 together with the moving magnet 121. From the center of the housing 105 toward the stator magnet 112 (see Fig. 2b). In addition, the rivet 132 moves together with the movable magnet 112 from the stator magnet 113 toward the stator magnet 112 at or near the center of the housing 105 and moves upward along the straight line shown in FIG. 3. do.

When the slide actuator 100 reaches the intermediate position shown in Fig. 3, the slide actuator 100 reaches the "turn point", at which point the rivet 132 continues to move upward and moves with the moving magnet 121. Magnetic repulsion between the N magnetic poles of the stationary magnet 112 and magnetic repulsion between the moving magnet 122 and the S magnetic poles of the stationary magnet 112 cause the moving magnets 121 and 122 to move to the stationary magnets 111 and 113. Act on each side). When the housing 105 is rotated past the intermediate position with respect to the rivet 131, the actuator 100 continues to face upwardly inclined position shown in FIG. The movement of the actuator 100 from the intermediate position to the open position may be assisted by magnetic repulsive or repulsive forces acting to push the moving magnets 121 and 122 toward the stator magnets 111 and 113, respectively. When the slide actuator 100 is close to the open position, the magnetic attraction between the opposite N and S magnetic poles of the stationary magnet and the moving magnet can also move the slide actuator 100 toward the open position. In some embodiments, the magnetic repulsion and magnetic attraction between the magnets may be strong enough to automatically move the slide actuator 100 from the intermediate position to the open position (and also from the intermediate position to the closed position).

In addition, when the terminal body parts 51 and 52 reach the open position, the magnetic force between the N magnetic poles and the S magnetic poles of the stationary magnet and the moving magnet opens the actuator 100 and the terminal body parts 51 and 52. Act to bias (also hold) to position. When the user slides the terminal body to close the terminal, the actuator 100 returns the positions shown in FIG. 3 to the reverse direction, that is, from the upwardly inclined position to the downwardly inclined position through the intermediate position. Therefore, the slide actuator 100 can operate to move the slide actuator 100 from the turning point or the intermediate point toward the open position or the closed position by the magnetic attraction and the magnetic repulsion of the magnets.

4A and 4B show another exemplary embodiment of a slide actuator 200 that can be used in a portable terminal. 4A shows one arrangement in which the slide actuator 200 is actuated when the terminal is reaching the first or closed position or is reaching the second or open position. 4B shows one arrangement in which the slide actuator 200 is actuated when the terminal is in an intermediate or neutral position (or a turning point) (described further below) between the open and closed positions. The actuator 200 has a housing 205 that can be disposed between the sliding body portions (eg, the body portions 51 and 52 shown in FIG. 6) of the mobile terminal. A portion of the actuator 200 is rotatably connected to the first body portion by means of connectors, such as rivets 231 and the like. The other part of the actuator 200 is rotatably connected to the second body portion by another connector, such as a rivet 232 or the like. In other embodiments, the actuator 200 may have other means for rotatably connecting the actuator to the portable terminal instead of the rivet.

With continued reference to FIGS. 4A and 4B, magnets are retained in housing 205. The magnets are aligned and held in some form. In Figs. 4A and 4B, the letters N and S side by side represent the N and S poles of the magnet, respectively. The magnets include a plurality of stator or stationary magnets fixedly disposed in the housing 205. For example, the stator magnet 211 is disposed at one end of the housing 205. Another stator magnet 212 is disposed at the other end of the housing 205. In the illustrated embodiment, the stator magnets 211 and 212 are arranged such that the S-poles repel against each other. When the housing 205 slides rotatably between the terminal body portions, the moving magnet 221 is moved within the housing 205 and between the stator magnets 211 and 212 (indicated by a double-headed arrow in FIG. 4A). Movable along 205. The rivet 231 is coupled to the stator magnet 211. The rivet 232 is coupled to the mover magnet 221 and is movable together with the mover magnet 221.

The polarities of the moving magnet 221 and the stator magnet 212 are arranged to attract the magnets 221 and 212 to each other. On the other hand, the moving magnet 221 and the stationary magnet 211 is arranged to repel each other. In this embodiment, the stator magnet 211 exhibits a magnetic force greater than that of other magnets, thereby improving the tendency to move the moving magnet 221 toward the stator magnet 212.

Exemplary operation of the slide actuator 200 will be described with reference to FIGS. 4A, 4B and 5. In this embodiment, when the actuator 200 is rotated between the terminal body portions, the actuator 200 passes through the positions shown in FIG. In FIG. 5, positions in which the actuator 200 is tilted downward or upward correspond to the closed position and the open position of the portable terminal. When the terminal is opening from the closed position or closed from the open position, the actuator 200 moves past the intermediate position shown horizontally in FIG.

For example, when the terminal is closed, the actuator 200 is located in a downwardly inclined position shown in FIG. The moving magnet 221 is located near the stationary magnet 212 (see FIG. 4A). When the user of the terminal opens one terminal by sliding one of the terminal body parts with respect to the other one of the terminal body parts, the slide actuator 200 moves from an inclined downward position to an intermediate position (shown horizontally in FIG. 5). do. Specifically, the rivet 231 connected to one of the terminal body parts and the stator magnet 211 acts as a pivot in which the actuator 200 can rotate about it. Rivet 232 is moved upward along the straight line as shown in FIG. At the same time, as shown in FIGS. 4A and 4B, the rivet 232 moves together with the moving magnet 221 from the stator magnet 212 toward the stator magnet 211 at the other end of the housing 205.

When the slide actuator 200 reaches the intermediate position, the slide actuator 200 reaches the "turning point" at which the magnetic repulsion between the moving magnets 221 and the N magnetic poles of the stator magnet 211 is moved. And acts to push 221 toward the stator magnet 212. When the housing 205 is rotated past the intermediate position with respect to the rivet 231, the actuator 200 continues to face toward the upwardly inclined position shown in FIG. Movement of the actuator 200 from the intermediate position to the open position may be assisted by magnetic repulsive or repulsive forces acting to push the moving magnet 221 toward the stationary magnet 212. When the slide actuator 200 is close to the open position, the magnetic force between the N and S magnetic poles of the stationary magnet 212 and the moving magnet 221 may move the slide actuator 200 toward the open position. In some embodiments, the magnetic repulsion and magnetic attraction between the magnets may be strong enough to automatically move the slide actuator 200 from the intermediate position to the open position (and also from the intermediate position to the closed position).

In addition, when the terminal body portions reach the open position, the magnetic attraction between the opposite N and S magnetic poles of the stationary magnet 212 and the moving magnet 221 biases the actuator 200 and the terminal body portions to the open position. It also acts to maintain). When the user slides the terminal body to close the terminal, the actuator 200 returns to the downward angle position from the position shown in FIG. 5 to the reverse direction, that is, from the upwardly inclined position. Therefore, the slide actuator 200 can operate to move the slide actuator 200 from the turning point or the intermediate point toward the open position or the closed position by the magnetic attraction and the magnetic repulsion of the magnets.
