The present invention relates to a slide-type cover opening and closing device for a mobile terminal, and more particularly, to improve the elastic efficiency of the elastic body is installed to open and close automatically made contact with the sliding contact when the cover opening and closing of the mobile terminal. The present invention relates to a sliding cover opening and closing device for a mobile terminal, which is configured such that the opening and closing operation of the mobile terminal, which is becoming larger and larger, can be made naturally and smoothly.

In general, in order to use services such as broadcasting and communication wirelessly while moving in places other than a fixed location, mobile terminals such as mobile phones, PDAs, notebook computers, and DMB phones are frequently used.

The portable terminal is one of the essential necessities indispensable in order to enjoy the convenience of life according to the development of the information industry, and the mobile phone is widely distributed to elementary, middle and high school students and the elderly.

In the portable terminal as described above, various methods are applied to open and close the cover, which can be divided into a hinge method, a slide method, and a swing method.

In particular, the portable terminal for opening and closing the cover by the slide method is one of the most applied in recent years because of various advantages such as easy to use, less trouble, and a stylish design.

The basic structure of the mobile terminal for opening and closing the cover by the slide method is a configuration for sliding the cover installed in the display unit up and down from the main body, the keypad is installed, the conventional sliding type opening and closing for the mobile terminal of various structures based on the basic structure Devices are manufactured around each manufacturer.

For example, the conventional sliding cover opening and closing device for a mobile terminal is formed in a plate shape and the first sliding member is fixed to the main body of the portable terminal and formed with guide projections at both corners, and formed in a plate shape and the portable terminal The second sliding member fixed to the cover of the rail member having a rail groove having a rail groove in which the guide projection of the first sliding member is slidably assembled at both edges, and the sliding of the second sliding member is more easily and smoothly. Both ends are rotatably coupled to and supported by the first sliding member and the second sliding member so as to be made.

The elastic body is configured such that the rest of the cover is naturally made by the elastic restoring force as the user applies a force to the cover until the first sliding member slides for a certain period in the open or closed state of the mobile terminal. do.

In the slide cover opening and closing device for a conventional portable terminal configured as described above, since sliding contact is made between the first sliding member and the second sliding member when the cover is opened and closed, the friction is increased when the portable terminal is large or has a large load.

That is, since the contact area between the guide protrusion of the first sliding member and the rail groove of the second sliding member is increased or the friction force is increased, the opening and closing operation of the cover tends to be poor.

In addition, the conventional sliding cover opening and closing device for a mobile terminal is in contact with the first sliding member and the second sliding member due to the sag of the intermediate part by using a coil spring or a torsion spring as an elastic body, so that the first sliding member and the second sliding member are in contact with each other. It will damage the sliding member.

In addition, when manufacturing an elastic body using a metal material, it is difficult to manufacture and productivity is reduced because a ring for rotatably coupling the first sliding member and the second sliding member to both ends of the elastic body.

In addition, the ring of the elastic body may be damaged by friction with the first sliding member and the second sliding member, and when the friction is severe, noise may occur or rotational motion may be disturbed.

Furthermore, since the elastic body may flow up and down during the sliding operation, it is difficult to accurately and smoothly open and close the operation.

Moreover, in the conventional slide cover opening and closing device for a mobile terminal, assembling is reduced by performing riveting or punching to couple the ring of the elastic body to the first sliding member or the second sliding member, thereby increasing production efficiency. Difficulties are encountered and manufacturing costs are also limited.

An object of the present invention is to solve the above problems, the portable projection is a sliding contact and the roller is in contact with the roller at the same time the sliding contact with the roller at the time of opening and closing of the cover of the mobile terminal is carried out smoothly and smoothly opening and closing It is to provide a sliding cover opening and closing device for the terminal.

In addition, another object of the present invention is to collect a plurality of compression coil springs in one place so that the force is concentrated, the elastic force is improved, and because the compression coil spring is not exposed to the outside for reducing or damaging the force due to friction and flow for mobile terminals To provide a sliding cover opening and closing device.

According to the sliding cover opening and closing device for a mobile terminal according to the present invention made as described above, the guide projection of the first sliding member is in sliding contact along the rail groove of the rail member at the time of opening and closing the cover of the mobile terminal and at the same time the wheel member of the roller and the rolling As a result of the contact, friction is reduced and flow is reduced.

Therefore, the cover opening and closing operation is smooth and smooth even when applied to a large portable terminal.

And since the stop groove is formed so that the wheel member of the roller is inserted into the guide projection of the first sliding member to stop, the movement of the cover is naturally stopped at the opening and closing position.

According to the sliding cover opening and closing device for a mobile terminal according to the present invention, since the structure of the elastic body is made to concentrate the force by gathering several compression coil springs in one place to improve the elastic force acting when opening and closing the cover of the mobile terminal. It is possible.

Therefore, even in the case of large portable terminals, the elastic force is not degraded and the opening and closing operation of the cover is made smoothly and smoothly.

In addition, since the compressed coil spring of the elastic body is wrapped and supported by the rotary support plate, it does not contact the first sliding member and the second sliding member due to deflection of the intermediate portion of the compressed coil spring, and thus damages the first sliding member and the second sliding member. Do not wear.

According to the slide-type cover opening and closing device for a mobile terminal according to the present invention, it is not necessary to form a ring-shaped ring or the like at both ends of the compression coil spring, the production is easy and productivity is improved.

That is, the mass production is advantageous as compared to forming a ring by bending both ends of the conventional compression coil spring, thereby improving productivity and reducing manufacturing cost.

According to the slide-type cover opening and closing device for a mobile terminal according to the present invention, assembling of the hinge pin for rotatably supporting the elastic body is easy and simple structure, thereby improving assembly.

Therefore, the production efficiency can be increased and manufacturing cost can be reduced as compared with the conventional assembly structure such as riveting.
