The opening and closing device according to the present embodiment includes a first body (not shown) that includes a main board that performs various functions of the portable terminal and slides in one direction from the first body (not shown) to which the display device is mounted. 2 body (not shown), the guide rod 300 placed in the direction in which the second body (not shown), the first body (not shown) is fastened and fixed and coupled to one side of the outer peripheral surface of the guide rod 300 The first plate 200 with the guide groove 230, the second body (not shown) is fixed to the guide to be coupled to the slide movement on one side of the remaining outer peripheral surface of the guide rod 300 coupled to the first plate 200 The second plate 100 having the ribs 120 formed thereon, the second plate 100 to absorb the shock generated by the slide movement between the first plate 200 and to buffer the movement of the guide rod 300 Damper 400 It includes.

In addition, the second plate 100 is preferably made of a slide further comprises an elastic means 500 for generating an elastic force.

The first body (not shown) and the second body (not shown) operate together to form a major part of the portable terminal, and are interconnected by a flexible PC to electrically transmit and receive signals. The first plate 200 is coupled to the first body (not shown) and the second plate 100 is coupled to the second body (not shown), so as to slide in one direction of the first plate 200.

The present invention is intended to mitigate the multi-directional shock generated between the first plate 200 while the second plate 100 repeatedly slides, and to reduce the harmfulness of the slide operation that can be formed by various factors.

The guide rod 300 installed for this purpose, the second plate 100 is easily slid by using a material having good surface roughness and strength, and the guide rod 300 is not deformed due to repetitive flow. .

On the other hand, the guide rod 300 is a guide rod for the direction in which the second plate 100 is moved (in order to reduce the hazard related to operation hazards due to component deviations and improve the assemblability when assembling each component of the present embodiment) It is preferable that the cross section of 300 is made circular.

The first plate 200 has guide grooves 230 formed at both sides for coupling of the guide rods 300 in one direction in which the second plate 100 slides, and guide rods 300 in the guide grooves 230. There is an assembling hole 220 for mounting and fixing), the first fastening hole 210 is coupled to one side of the elastic means 500 for generating an elastic force while the slide is moved, the fastener for coupling the damper 400 The unit 240 is included.

Since the guide groove 230 is closely coupled to one side of the outer circumferential surface of the guide rod 300, the guide groove 230 is preferably formed in a semicircular structure according to a preferable circular cross-sectional shape of the guide rod 300.

The second plate 100 is in close contact with the guide groove 230, the guide rib 120 is formed to be coupled to the outer peripheral surface exposed to the outside of the guide rod 300 coupled to the first plate 200, the first The second fastening hole 110 is coupled to one side of the elastic means for automatically sliding the plate while moving the initial slide on the plate 200 by the external force is included.

Since the guide rib 120 has a shape in which a relatively circular cross-sectional shape of the guide rod 300 is relatively wrapped together with the guide groove 230, the second rib 100 is slid to move in a semicircular structure. desirable.

The damper 400 has a shape corresponding to the fastening part 240 so as to be coupled to the fastening part 240 of the first plate 200, the coupling hole 410 for the guide rod 300 to penetrate through the coupling. Is provided.

The coupling rods 410 of the damper 400 are fastened to both sides of the guide rod 300, respectively, and are inserted and fixed to the fastening portion 240 of the first plate 200, the guide rod 300 is substantially It is coupled to the first plate 200 through the damper 400.

In addition, the damper 400 is coupled to the guide rods 300 at both ends of the second plate 100 slide movement, so that the second plate 100 slides and is generated with the first plate 200 To absorb the shock, the guide rod 300 is made of an elastic material to act as a buffer against the vibration in the direction other than the slide movement axis.

The damper 400 of this embodiment is made of a rubber material.

That is, the damper 400 buffers and compensates the microscopic movement of the guide rod 300 in various directions, thereby further improving the assemblability between components during assembly, while the second plate 100 repeatedly slides and moves. Due to the deformation of the parts, etc., the harmfulness of the slide operation may be overcome and the second plate 100 may be smoothly moved.

The elastic means 500 has a first block 510 to be rotatably coupled to the first point of the first plate 200 by the second hinge shaft 600, and the movement path coincides with the first point. There is a second block 530 to be rotatably coupled by the second hinge axis 600 at a second point of the second plate 100 that is not, and the second plate 100 receives an elastic force as the slide moves. It comprises a compression spring 520 for.

The first block 510 is located in the closing direction from the second block 530 when the second plate 100 is in the closing position on the basis of the inflection point of the movement path of the second plate 100, thereby providing elastic means. The elastic force of 500 acts in the direction in which the second plate 100 is closed.

When the second plate 100 is in the open position, the second plate 100 is positioned in the open direction from the second block 530 so that the elastic force of the turnable member acts in the direction in which the second plate 100 closes.

Hereinafter will be described the operation of the preferred embodiment of the switching device according to the present invention.

In a state where no external force is applied, the second plate 100 is maintained in a closed state by the pushing force of the first block 510 which is subjected to the elastic force of the compression spring 520.

In this state, when the second body (not shown) is pushed by hand to open the second plate 100 on which the display device of the portable terminal is mounted, the second plate 100 coupled with the second body (not shown) is The slide is moved. At this time, the guide rib 120 of the second plate 100 is linearly moved along the guide of the guide rod 300 fixed to the first plate 200.

The damper 400 elastically buffers the guide rod 300 trembling in a direction perpendicular to the slide moving axis while performing the linear motion as described above, thereby allowing the second plate 100 to slide more smoothly.

When the second plate 100 is opened, the force that prevents the second plate 100 from opening as the second plate 100 pushes the first block 510 and the compression spring 520 is compressed to increase the elastic force. This action, and overcomes this force and continue to move past the inflection point, the first block 510 pushes the second plate 100 in the opening direction again by the elasticity of the compression spring 520, from this time on automatically Move to the open position.

In addition, the second plate 100 is maintained in the open state by the pushing force of the first block 510 is subjected to the elastic force of the compression spring 520.

In addition, the closing process is also performed in the reverse order of the above process.

As described above, the second plate 100 is opened and closed by the elastic force to alleviate the shock generated between the first plate 200 and the second plate 100 due to the dampers 400 positioned at both ends of the slide moving direction. It protects the parts embedded in the terminal.

While specific embodiments of the present invention have been described and illustrated above, it will be apparent that the present invention may be embodied in various modifications by those skilled in the art. Such modified embodiments should not be understood individually from the technical spirit or the prospect of the present invention, but should fall within the claims appended to the present invention.

Therefore, in the present invention, there is an advantage of improving the structure of the slide moving portion of the opening and closing device of the portable terminal, thereby reducing component harmfulness to the slide operation and making the slide movement more smoothly.
