Terminal {Terminal}

An embodiment relates to a terminal.

As a type of opening and closing of a conventional terminal, a folding type and a sliding type are used.

In the slide-type terminal, the terminal may be damaged due to the shock generated by the relative movement between the fixed part and the moving part while the opening and closing operation is repeatedly performed. In addition, when the relative speed of movement between the fixed part and the moving part is large, the impact noise may have a negative effect on the consumer's emotion.

The embodiment provides a terminal capable of preventing the impact caused by the relative movement between the fixing unit and the moving unit during the opening and closing operation of the slide type.

According to an embodiment of the present invention, a terminal includes a fixing part including a keypad and a moving part which performs a slide movement relative to the fixing part and is provided with an image display part, and is provided to any one of the fixing part and the moving part. And a magnet structure and a conductor provided on the other of the fixed part and the moving part.

According to an embodiment of the present invention, a terminal includes a first body provided with a conductor and a second body provided with a magnetic structure on one surface corresponding to a position at which the conductor is provided and performing a slide movement relative to the first body. It includes.

The terminal according to the embodiment has an advantage of preventing the shock caused by the relative movement between the fixed portion and the moving portion during the slide-shaped opening and closing operation.

Hereinafter, exemplary embodiments will be described with reference to the accompanying drawings.

1 and 2 conceptually illustrate a terminal according to an embodiment.

The terminal according to the embodiment includes a moving unit 100 and a fixing unit 200. An image display unit 110 may be provided to the moving unit 100, and a keypad 210 may be provided to the fixing unit 200.

The moving unit 100 and the fixing unit 200 may perform a slide movement relatively, and the opening and closing of the terminal may be implemented according to the slide movement. Since the moving unit 100 slides on the upper surface of the fixing unit 200, the moving unit 100 may mount the enlarged image display unit 110. The image display unit 110 may be implemented as a liquid crystal display panel or an organic light emitting display panel. Since such a terminal can provide the image display unit 110 and the keypad 210 separately, the overall size of the terminal can be reduced.

According to an embodiment of the present disclosure, a magnet structure may be provided to any one of the moving part 100 and the fixing part 200, and a conductor may be provided to the other. In the embodiment illustrated in FIG. 2, the magnetic structure 120 is provided on the lower surface of the moving part 100, and the conductor 220 is provided on the upper surface of the fixing part 200.

The magnet structure 120 may include a permanent magnet, and a back yoke may be provided on the rear surface of the permanent magnet. In addition, the magnet structure 120 may include an electromagnet, and a back yoke may be provided on the back of the electromagnet. The magnet structure 120 may be formed on the entire lower surface of the moving part 100, or may be formed in a partial region. The magnet structure 120 may be formed integrally with the moving part 100 or may be formed in a separate fixed form.

The conductor 220 may be formed on the entire upper surface of the fixing part 200 or may be formed in a partial region. However, the terminal according to the embodiment is implemented such that the magnetic structure 120 can pass through the region in which the conductor 220 is disposed by the relative movement between the fixing part 200 and the moving part 100. In addition, a back yoke may be provided on the rear surface of the conductor 220.

According to an embodiment of the present disclosure, a magnetic force line formed in the magnet structure 120 and an eddy current induced in the conductor 220 as the magnet structure 120 passes through a region where the conductor 220 is disposed. Due to the interaction by the eddy current, the relative movement between the fixed part 200 and the moving part 100 can be reduced.

A slide type opening and closing operation of the terminal according to an embodiment will be described with reference to FIGS. 3 and 4.

As shown in FIG. 3, the magnet structure 120 may include a plurality of magnets 121, 122, 123, 124, 125, and 126. The plurality of magnets may be arranged in a matrix form as an example, and the arrangement may be variously modified as necessary. In an embodiment, the polarities of the magnets 122, 124, and 126 disposed in front of the magnets 120, 124, and 126 disposed behind the magnet structure 120 are different from each other. For example, if the surface polarity of the magnets 122, 124, 126 placed in front is the S pole, the surface polarity of the magnets 121, 123, 125 placed behind provides the N pole.

As described above, the magnet structure 120 includes a plurality of magnets arranged with alternating polarities in a relative movement direction between the fixed part 200 and the moving part 100. In addition, the magnet structure 120 includes a plurality of magnets having the same polarity in the vertical direction with respect to the relative movement direction between the fixing part 200 and the moving part 100.

When relative movement between the magnet structure 120 and the conductor 220 occurs, the projection region ①, ②, ③, ④, ⑤, ⑥ of the conductor 220 may have an induction current. Something happens. Since the induced current forms a vortex, it is also called an eddy current. Areas ①, ②, ③, ④, ⑤, and ⑥ indicated on the conductor 220 respectively indicate projected positions of the magnets 121, 122, 123, 124, 125, and 126 provided on the magnet structure 120. FIG. Indicates.

It can be seen that the directions of the eddy currents induced in the regions ①, ③, ⑤ projected on the conductor 220 and the directions of the eddy currents induced in the projected regions ②, ④, ⑥ are opposite to each other. This depends on the polarity of the magnets 121, 122, 123, 124, 125, and 126. In an embodiment, the magnets 122, 124, and 126 disposed in front of the magnet structure 120 based on the traveling direction of the magnet structure 120. ) And the magnets 121, 123, and 125 arranged behind are implemented to have different polarities.

The eddy current components induced in the projected areas ①, ③, and ⑤ merge with each other, and the eddy current components induced in the projected areas ②, ④, and ⑥ also merge with each other.

In addition, the phenomenon in which the eddy current components induced in the projected regions ① and ② are combined with each other occurs, and the eddy current components induced in the projected regions ③ and ④ and the eddy current components induced in the projected regions ⑤ and ⑥ are also different from each other. The phenomenon of summation occurs.

As described above, a plurality of magnets are arranged in the magnet structure 120 with the polarity alternately in the relative movement direction between the fixing part 200 and the moving part 100, thereby obtaining more efficient attenuation characteristics. In addition, a plurality of magnets having the same polarity in the vertical direction with respect to the relative movement direction between the fixed part 200 and the moving part 100 are disposed on the magnet structure 120, thereby further reducing efficiency. .

The Lorentz force is generated by the interaction between the eddy current shown in FIG. 3 and the magnetic force line shown in FIG. 4. As described above, when the fixing part 200 is relatively moved with respect to the moving part 100, a repulsive force is generated for the moving speed, thereby causing attenuation effect. Such a repulsive force is not generated when the relative speed is 0, and a larger repulsive force is generated as the relative speed is larger, thereby preventing the relative moving speed between the fixed part 200 and the moving part 100 from becoming larger than a set value. You can do it.

According to the terminal according to the embodiment, the moving unit 100 can control the degree of movement of the fixing unit 200. Accordingly, the moving part 100 can move at an appropriate speed in the fixing part 200, and can stably stop according to the attenuation effect. Accordingly, it is possible to prevent the moving part 100 or the fixing part 200 from being impacted by the opening and closing operation between the moving part 100 and the fixing part 200. In addition, it is possible to prevent the noise is generated by the opening and closing operation between the moving unit 100 and the fixing unit 200.

In the terminal according to the embodiment, the shapes of the magnets 121, 122, 123, 124, 125, and 126 have a circular cross section. Thus, the magnets 121, 122, 123, 124, 125, and 126 have a circular cross section, so that more eddy currents can be induced than other magnets having the same area (for example, magnets having a rectangular cross section). .

The description above has been described based on the case in which the magnetic structure 120 is provided on the lower surface of the moving part 100 and the conductor 220 is provided on the upper surface of the fixing part 200. However, a magnetic structure may be provided on an upper surface of the fixing part 200, a conductor may be provided on a lower surface of the moving part 100, and the magnetic structure may be integrally formed with the fixing part 200, or It may be provided in a separate fixed form.

On the other hand, such a slide-type opening and closing structure can be applied to various structures having a slide movement in addition to the mobile communication terminal.

That is, the structure according to the embodiment, for example, the terminal, is provided with a first body provided with a conductor on one surface, and a magnet structure provided on one surface corresponding to a position where the conductor is provided, and performs a slide movement relative to the first body. It may include a second body.

The magnet structure may include at least one of a permanent magnet and an electromagnet. Due to the relative movement between the first body and the second body, the magnet structure passes through a region in which the conductor is disposed, and interacts with a magnetic force line formed in the magnet structure and an eddy current induced in the conductor. As a result, the relative movement between the first body and the second body can be slowed down.

The magnet structure may be formed integrally with the second body or may be formed in a separate fixed form. The magnet structure may include a plurality of magnets arranged with alternating polarities in a relative movement direction between the first body and the second body. In addition, the magnet structure may include a plurality of magnets having the same polarity in the vertical direction with respect to the relative movement direction between the first body and the second body. The magnet structure may allow a shape of a surface facing the conductor to be formed in a circular shape.
