Description

Cellular phone slim slide-hinge assembly}

The present invention relates to a hinge assembly of a slide-type personal portable terminal that is opened and closed by a vertical slide method, and more particularly interposed a predetermined hinge module between the upper housing and the lower housing constituting the mobile phone body to implement the slide of the mobile phone. By doing so, the link spring on the other side pivots around the link spring arranged on one side, thereby promoting the slide operation of the mobile phone, thereby reducing the overall slide hinge thickness and the number of parts and improving the assembly. The present invention relates to a slim slide hinge assembly for a mobile phone, which can improve the strength of the product by distributing the stress applied to the spring due to the buffering action of the end portion and the middle portion of the link spring, and at the same time, to realize slimming.

In general, as the personalization of portable wireless terminals has become more common, mobile phones with various additional functions and designs are being released to meet the needs of users in addition to the basic functions of talking with the other party. The mobile phones have been developed from general bar type mobile phones to flip type mobile phones, flip-up mobile phones, and folder type mobile phones. It is coming true. This is because a folder-type mobile phone has enough space to adopt a wide LCD module as a display device, and because it is folded in half, the portability is also superior to other mobile phones.

In recent years, a mobile phone having a wide LCD module having a size similar to that of the above-described folder type mobile phone can be provided, and at the same time, a mobile phone of a type that can meet various needs of users by contributing to miniaturization of the mobile phone has been released. This is a slide type terminal in which a slide body is opened by sliding a predetermined length in a length direction of the terminal on a predetermined main body, and has an advantage in that it can meet various user's changing preferences compared to a conventional folder type terminal. Type.

The slide-type mobile phone may be configured in a state in which the slide body is opened by sliding downward or upward to about 1/2 of the main body length when viewed based on the main body.

Referring to the slide hinge module for a conventional mobile phone for implementing the sliding as described above, the conventional slide hinge module is a guide rail member; and a slide member that slides on the guide rail member; and the slide member First and second torsion springs to help; Or other flexible wire springs; springs bent to various shapes. The above-described method is a method in which each hole is formed near the center near both edges of the rectangular plate, and one arm of the first torsion spring and one arm of the second torsion spring are pivotally inserted into the hole.

Meanwhile, the flexible wire spring may include a coil elastic part bent in a spiral shape, a first wire part extending from one end part disposed relatively outward from a center of the coil elastic part among both ends of the coil elastic part, and the coil elastic part. It is common to comprise the 2nd wire part extended in the direction different from a 1st wire part from the one end arrange | positioned relatively inward from the center of a coil elastic part among both ends.

Such a spring is installed between mutually moved objects to allow the mutual movement of each object to be elastically, for example, the spring includes a body portion and a slide portion coupled to the main body portion to be relatively slidable. In the slide-type personal portable terminal can be applied to a conventional sliding assembly for connecting the main body portion and the slide portion relative sliding.

As described above, the conventional torsion spring applied to the hinge assembly of the slide mobile phone is usually formed by bending a metal wire so as to have a small diameter cylindrical shape, the structure of which is a rail plate and a slide from both ends of the central coil portion and the coil portion, respectively. Including a hinge extending wire connection bar, because one of the wire connection portion extends from the center of the coil portion is part of the overlapping up and down to form a relatively double thickness.

The torsion spring is configured to have a diameter of about 0.5 mm so that the overlapping portion of the wire is formed at a thickness of about 1.0 mm, which is twice the diameter, so that the height between the rail plate and the slide hinge is at least about 1.0 mm or more. Must be able to provide space with Considering the recent development of a slide hinge device having a thickness of about 2 ~ 3mm, the clearance space of about 1.0mm or more can not be a big obstacle in reducing the thickness of the slide hinge device.

A method of reducing the clearance space by reducing the diameter of the torsion spring may be proposed, but the smaller the diameter of the spring, the elastic force is also lowered, so that the slide movement between the upper and lower housings forming the mobile phone body is not smooth and the semi-automatic opening and closing function of the mobile phone There is a fear that this may be reduced. As a result, it will be obvious that other adverse effects will be produced, such as a lack of reliability in operation and a reduction in operating life.

In addition, the conventional hinge assembly as described above is very complex in order to perform each function normally, and the thickness of the entire slide hinge is not only thickened by the use of the first and second torsion springs, but also when applied to a product. Due to the limited length of the stroke, it is not widely used, and many types of parts face a closed end which increases the manufacturing cost.

On the other hand, in the case of the spring used in the conventional hinge, such as shown in Figure 1, by processing the material in a coil shape applied to the device it is a fatal problem that does not disperse the repetitive stress applied to the spring during the life test Occurs, and it is difficult to operate while maintaining the balance due to its structural characteristics. That is, the conventional spring has a problem that the coil elastic portion and each wire portion is difficult to operate in a state of equilibrium in one plane due to the torsion as the coil elastic portion is formed bent, which means that the flow occurs during spring operation .

Furthermore, in the related art, a part of a spring contacts an adjacent peripheral part by the flow generated during spring operation, and as a result of interference, wear occurs on the mutual contact area between the spring and the peripheral part, and operation noise is generated. There is a problem of this deterioration, as well as a space for allowing the flow of the spring between the subject to be prevented in order to prevent the interference caused by the flow of the spring operation, and thus the space utilization of the subject on which the spring is mounted and There is a problem that the design freedom is lowered.

The present invention has been made to actively solve the above problems,

In configuring the hinge assembly of the slide-type mobile phone to be opened and closed by the vertical sliding method, a predetermined configuration is formed between the upper housing and the lower housing forming the mobile phone body by forming a spring material as a link type consisting of a plurality of curved portions instead of a coil shape. The problem solving means of the present invention is to implement the slide operation of the mobile phone by the way that the other side of the link spring is pivoted around the link spring disposed on one side by interposing with the element.

According to the present invention implemented by the above-mentioned means for solving the problem, not only reduces the thickness and the number of parts of the slide hinge and improves the assembly, but also the stress applied to the spring due to the buffer action of the end portion and the intermediate portion of the link spring Dispersion improves the strength of the product and at the same time has the effect of realizing a slim.
