And, a pair of moving switching spring 130 is installed between the guide plate 111 and the slider 120, the separation position stopper 142 and the alignment position stopper coupled to the top and bottom of the guide rail 110, respectively ( 141).

In addition to the guide plate 111, the guide rail unit 110 has sliding rails 112 formed on both side edges of the guide plate 111 along the longitudinal direction.

The guide plate 111 is formed such that a pair of spring mounting holes 111a are located in the outer arm 133 engaging region of each of the movement switching springs 130 to be described later.

In addition, the guide plate 111 is formed in a rectangular shape in which the PC rain opening 111b for passing the FPCB (Flexible Printed Board) electrically connecting the lower body and the upper body of the mobile phone to the lower region.

Guide rail portion 110 having such a configuration is usually fixed to the bottom of the lower body of the mobile phone.

The slider 120 has a rectangular sliding plate 121 and a pair of sliding portions 122 formed at both edges of the sliding plate 121, respectively.

The sliding plate 121 is spaced apart from the guide plate 111 by a distance greater than twice the diameter of the moving switching spring line (from the inner arm and the spiral section once) so as to secure the flow section of the pair of the moving switching springs 130. It is. Accordingly, the separation distance between the sliding plate 121 and the guide plate 111, that is, the thickness of the mobile phone is determined by the line diameter of the movement switching spring.

And the sliding plate 121 is formed so that a pair of rivet holes (121a) is located in the inner arm 132 coupling region of each movement switching spring 130 to be described later.

In the sliding portion 122, a rail hole 122a is formed over the entire length section.

The slider 120 is installed in the guide rail portion 110 so that the sliding rail 112 is inserted into the rail hole 122a. As a result, the slider 120 may be slidably moved to the guide rail unit 110.

Slider 120 having this configuration is usually fixed to the bottom of the upper body of the mobile phone.

Each of the movement switching springs 130 is formed to have a circular cross section and extends outward of the inner arm 132 and the spiral portion 131 extending from the inner side of the spiral wound portion 131 and the spiral portion 131. It has the outer arm 133 made.

The outer arm 133 and the inner arm 132 are formed to have a substantially right angle. The end of the outer arm 133 is bent twice to form a needle-shaped shape, and the end of the inner arm 132 is formed with an approximately " O " shaped ring portion 132a.

A pair of the movement switching spring 130 having such a configuration is fixed to the guide plate 111 and the sliding plate 121 in the region between the guide plate 111 and the sliding plate 121 as follows.

One of the pair of movement switching springs 130 is installed so that the outer arm 133 is approximately parallel to the sliding rail 112, and the other one is installed so that the outer arm 133 is inclined to the sliding rail 112. .

And the inner arm 132 of each movement switching spring 130 is coupled to the sliding plate 121 through rivets (143, Rivet) installed in the rivet hole (121a) in the state inserted into the fixing ring portion (132a), The outer arm 133 is coupled to the guide plate 111 by forcibly inserting the end into the spring mounting hole 111a of the guide plate 111.

Accordingly, the outer arm 133 and the inner arm 132 of the movement switching spring 130 are rotatable while the slider 120 moves along the longitudinal direction of the guide rail unit 110, and the guide plate 111. There is formed a switching position in which the sliding movement direction of the slider 120 is switched.

Here, the switching position is formed at the movement position of the sliding plate 121 when the inner arm 132 of the pair of movement switching springs 130 is disposed substantially along the longitudinal direction of the guide rail portion 110 (FIG. 12). Reference).

The amount of elastic force accumulated in the mobile switching spring 130 at the switching position is selected in consideration of the convenience of use by the mobile phone manufacturer, and the magnitude of the elastic force accumulated in the mobile switching spring 130 is the line diameter of the mobile switching spring 130. Determined by Herein, the magnitude of the elastic force accumulated in the movement switching spring 30 increases as the line diameter of the movement switching spring 30 increases.

The operation of the conventional sliding type mobile phone hinge having the above-described configuration will be described with reference to FIG. For convenience of explanation, it is assumed that the slider 120 is in pressure contact with the alignment position stopper 141 (the upper body and the lower body are aligned, that is, overlapped with the slider being in pressure contact with the alignment position stopper).

First, when the slider 120 is moved toward the release position stopper 142, the elastic force is accumulated in the pair of the movement switching spring 130. The elastic force accumulation in the movement switching spring 130 continues until the slider 120 reaches the switching position.

When the slider 120 passes through the switching position, the slider 120 is accelerated toward the release position stopper 142 by the elastic force accumulated in the movement switching spring 130.

The movement of the movement switching spring 130 occurs in the same way when moving the slider 120 from the separation position stopper 142 to the alignment position stopper 141.

Each of the movement switching springs 30 is formed such that the side elastic portion 33 and the fixed arm 32 are linearly symmetric with respect to the center of the central elastic portion 31.

And a pair of moving switching spring 30 is formed to have a rectangular cross-section, the central elastic portion 31 is disposed to face.

The pair of moving switching springs 30 having such a configuration are coupled to the guide plate 11 and the sliding plate 21 by inserting both ends of the fixed arm 32 into the arm support groove 51c of the bush clip 50. . Accordingly, the movement switching spring 30 is rotatable while the slider 20 moves along the longitudinal direction of the guide rail portion 10.

Here, the coupling between the guide plate 11 and the sliding plate 21 of each movement switching spring 30 is such that the initial elastic force is accumulated in the central elastic portion 31.

The elastic force transmitted to the sliding plate 21 can be increased.

In addition, the fixed arms (32, 32 ') of each of the movement switching springs (30, 30') are formed to be line-symmetric with respect to the center of the central elastic portion (31, 31 '), the guide plate 11 and the sliding plate 21 By coupling the fixed arms 32 and 32 'of each of the moving switching springs 30 and 30' to the guide plate 11 and the sliding plate 21 so that the straight lines connecting the coupling points with each other are parallel to each other, the moving switching spring ( 30, 30 ') can be prevented from being concentrated at a specific point (deformation of the movement switching spring occurs symmetrically with respect to the central elastic part during the movement of the slider). Accordingly, it is possible to improve the life of the mobile switching spring (30, 30 ').

In addition, by coupling the movement switching spring (30, 30 ') to the guide plate 11 and the sliding plate 21 so that the initial elastic force is accumulated in the central elastic portion (31, 31'), from the movement switching spring (30, 30 ') The elastic force transmitted to the sliding plate 21 can be increased.
