Hinge module for portable terminal {HINGE MODULE FOR PORTABLE HANDHELD RADIOTELEPHONE}

The present invention relates to a hinge module of a folding portable wireless terminal, which is installed to open and close a predetermined sub-body on a main body at a predetermined angle. In particular, the terminal is not opened and closed arbitrarily, due to frequent operation of the hinge shaft and the hinge cam. A hinge module of a portable radio terminal configured to prevent damage in advance and to improve the assembling of the hinge module.

As portable wireless terminals become more and more popular, terminals of various functions and designs are appearing. In addition, the terminal is becoming smaller and lighter and smaller, and at the same time, the diversity of its functions is being highlighted. Therefore, in order to satisfy the needs of the consumers as described above, there is an emphasis on reducing the volume of the terminal to the maximum while maintaining or improving the function.

On the other hand, while maximizing the variety of functions, the terminal is becoming lighter and shorter and more and more convenient for the user, the terminal manufacturers are racing to solve the inconvenience caused when the user uses the terminal.

Recently, a portable wireless terminal is a folder type consisting of a main body, which is a main body rather than a bar type, and a sub body, which is a folder installed to be opened and closed at a predetermined angle by a predetermined hinge module on the main body. type or flip-up type terminals are becoming mainstream. The reason for using such a folder type terminal is that the sub-body (including the flip cover or folder) connected to the main body protects a number of key buttons formed on the main body to prevent the malfunction of the device and plays the role of a negative reflector during a call. Because it collects the notes. Moreover, in the folder type terminal, the wide LCD module can be separately mounted in the folder portion, which is advantageous in miniaturizing the product and in implementing a variety of functions.

Typically, the folder type terminal is equipped with a hinge module for opening and closing the sub body at a predetermined angle on the main body. The hinge module not only designates a predetermined opening / closing angle of the sub body, but also serves to store the predetermined elastic force when folded so that the folder does not open arbitrarily.

The conventional hinge module has a structure in which a hinge shaft and a hinge cam are accommodated in a predetermined hinge housing so as to be respectively engaged with a hill portion and a valley portion, and press one end of the hinge shaft or the hinge cam with a predetermined elastic means. . In this case, either the hinge shaft or the hinge cam is installed to flow only in the axial direction, so that when the hinge cam or the hinge shaft rotates, the other element moves backward by using the pushing action of the hill portion and the valley portion. The retraction allows the user to feel the openness of the folder and provide the holding force to maintain the full open or closed position of the folder.

However, since the hinge module configured as described above does not have a separate shaft or is integrally formed on the hinge shaft and the hinge cam, the neck of the hinge shaft, which partially protrudes out of the hinge housing, is damaged due to frequent opening and closing operations of the terminal. The phenomenon often came up. In addition, even if there are separate shafts separated from the hinge shaft and the hinge cam, when the shaft is fixed, it uses a method of forcibly pressing a pin using a predetermined jig, which is cumbersome to assemble and disassemble separately. Inconvenient problem to use the jig of the will occur. Further, in the coupling structure of the valley portion and the hill portion of the hinge shaft and the hinge cam, the hill portion and the valley portion are formed in a straight line parallel with respect to the axial direction, so that they slide at one point (the complete opening and closing position of the terminal). The force acts, and thus an unnecessary opening and closing operation of the terminal may be performed, which causes a problem of inferior operation of the terminal.

The present invention is to provide a hinge module of a portable wireless terminal is configured to be easily assembled and disassembled without a separate tool such as a jig to solve the above problems.

Another object of the present invention is to provide a hinge module of a portable wireless terminal that can prevent the hinge shaft and the hinge cam from being damaged even if frequent opening and closing operations of the terminal are performed.

Still another object of the present invention is to provide a hinge module of a portable wireless terminal, which has a separate shaft separated from the hinge shaft and the hinge cam, thereby improving the operability of the module.

It is still another object of the present invention to provide a hinge module of a portable radio terminal configured to prevent arbitrary flow in a fully open or closed position of the terminal.

Still another object of the present invention is to provide a hinge module of a portable wireless terminal, which eliminates unnecessary operation of the terminal by improving the interlocking structure of the valley portion and the peak portion of the hinge shaft and the hinge cam.

In order to solve the above object, the present invention provides a predetermined housing in a hinge module of a folding portable wireless terminal composed of a main body and a sub body opened to have a predetermined angle on the main body. Within the hinge housing having a hinge housing having a portion, a hinge cam that is received in the hinge housing and is provided so as to be movable only in the axial direction, and a predetermined hill that engages with the bone portion of the hinge cam. A main body or sub-body in which a hinge module is installed so that a part thereof protrudes out of the hinge housing when the shaft portion is rotatably installed in the axial direction and extends from one side of the shaft portion and is received on the hinge housing. A hinge shaft having a fixed end fixed to the remaining portion of the hinge cam and the hinge It is installed so as to be interposed between the housing one end is supported by the inner surface of the hinge housing and the other end to the elastic means for pressing the hinge cam in the hinge shaft direction, and the hinge shaft, the hinge cam and the hinge housing sequentially The end portion of which protrudes outwardly of the hinge housing, the other end includes a hinge pin installed to be fixed to the hinge shaft, and a predetermined fixing means for fixing the hinge pin protruding from the hinge housing from being detached. It features.

In the hinge module according to the present invention, since the hinge cam and the hinge housing are formed and coupled in a non-circular shape, the hinge cam can flow only in the axial direction without rotating itself without a separate guide means or anti-rotation means. Can be.

More preferably, the ridge portion of the hinge shaft according to the present invention is formed in a conical shape gathered at one point with respect to the axial direction, and since the valley portion of the hinge cam is also formed in a shape corresponding to the ridge portion, the ridge portion and the valley shape are integrated. The addition does not flow arbitrarily after being incorporated. Therefore, it is possible to prevent the malfunction in which the terminal is opened and closed arbitrarily.

Even more preferably, the hinge pin according to the present invention is easily fixed to the housing because the hinge pin is mounted in the direction of the hinge cam at a hinge shaft in which a part of the hinge housing protrudes out of the hinge housing. (E-ring) allows the hinge module to be easily assembled and dismantled during maintenance.

Even more preferably, the hinge pin according to the present invention has a shaft so as to be separated from the hinge shaft and the hinge pin, and is inserted and fixed into the hinge shaft to rotate together with the hinge shaft, so that fatigue and cracks due to frequent opening and closing operations of the terminal It is possible to prevent damage caused by.

2 is an exploded perspective view of a hinge module according to an embodiment of the present invention, Figure 3 is a cross-sectional view showing a coupling state of the hinge module according to an embodiment of the present invention, the hinge module 10 according to the present invention ) Is a hinge housing 20 having a predetermined accommodating portion 21, elastic means sequentially received in the accommodating portion 21 of the hinge housing 20, the hinge cam 30, the hinge shaft 50 and And a hinge pin 60 fixed through the hinge shaft 50 and the hinge cam 30, and fixing means for fixing the hinge pin 60 on the hinge housing 20.

The hinge cam 30 is accommodated in the accommodating portion 21 of the hinge housing 20 and is installed to be movable only in the direction of the axis A. Therefore, the hinge cam 30 and the hinge housing 20 may be formed in a shape other than circular. In the drawings of the present invention, the cross section of the hinge cam 30 and the hinge housing 20 is formed in a rectangular shape. But it is not limited to this. One side of the hinge cam 300 is formed to form a predetermined valley portion 33. The valley portion 33 is formed in a pair to face each other, but may be formed at least two according to the opening and closing operation.

The hinge shaft 50 includes a shaft portion 51 accommodated in the accommodating portion 21 of the hinge housing 20 and a fixed end 52 integrally formed to extend from the shaft portion 51. . The shaft portion 51 has a ridge 53 formed in a corresponding shape so as to be engaged with the valley portion 33 of the hinge cam 30. At this time, the shaft portion 51 is accommodated in the accommodating portion 21 of the hinge housing 20 is installed so as to enable its own rotation about the axis A. In addition, the fixing end 52 which protrudes out of the hinge housing 20 when combined is fixed to the rest of the main body (110 of FIG. 1) or the sub-body (120 of FIG. 1) in which the hinge module 10 is installed. do. Accordingly, the fixed end 52 rotates with the main body or sub body which rotates relatively, and thus the shaft portion 51 integrally formed with the fixed end 52 also rotates together. Therefore, the hinge shaft 50 has a configuration that rotates in the hinge housing 20, the hinge cam 30 is pushed by the mountain 53 of the rotating hinge shaft 50 to rotate backwards without being rotated together The retraction operation is performed.

In the center of the hinge shaft 50 and the hinge cam 30, through holes 53 and 33 through which the shaft 61 of the hinge pin 60 to be described later are formed, respectively. At this time, at least the hinge cam 30 is preferably installed to be idle (idle) with respect to the shaft 61 of the hinge pin (60).

The ridge 53 of the hinge shaft 50 has a conical shape that converges with respect to the axis A in one point. Accordingly, the valleys 33 of the hinge cam 30 that are engaged with the hill 53 of the hinge shaft 50 are also formed in a corresponding shape. This is to continuously maintain the combined state of the ridge 53 and the valley 33 which are gathered as one point of the hinge shaft 50, and consequently malfunction by providing a holding force in the fully open or closed position of the terminal. This is to prevent. In addition, although not shown, in the present invention, although the ridge portion is formed in the hinge shaft and the valley portion is formed in the hinge cam, the shapes may be interchanged as long as they are conforming structures. That is, the valley part may be formed in the hinge shaft, and the mountain part may be formed in the hinge cam.

On the other hand, it is preferable to use a compression type coil spring (hereinafter referred to as a "hinge spring") 40 as the elastic means. The hinge spring 40 is installed in the accommodating portion 21 of the hinge housing 20, and more specifically, is installed with a predetermined elastic force between the hinge cam 30 and the hinge housing 20. Therefore, the hinge spring 40 is supported by the hinge housing 20 and serves to press the hinge cam 30 in the hinge shaft direction.

As described above, the hinge pin 60 penetrates through the hinge shaft 50, the hinge cam 30, and the hinge spring 40 from the hinge shaft 50, and then partially protrudes into the hinge housing 20. do. At this time, one end of the hinge pin 60 is fixed on the hinge shaft 50. Accordingly, the hinge pin 60 includes a shaft 61 passing through the hinge shaft 50, the hinge cam 30, the hinge spring 40, and the hinge housing 20, and one end of the shaft 61. Is formed in the fixing portion 62 and the other end of the shaft 61 is fixed to the hinge housing 20 by a predetermined fixing means after penetrating, the through hole 54 of the hinge shaft 50 The head 63 is formed to be larger than the inner diameter.

Preferably, the hinge pin 60 is configured to rotate with the hinge shaft 50. To this end, the head 63 of the hinge pin 60 is preferably fixed to rotate together when the hinge shaft 50 rotates. Accordingly, a recess 56 having a predetermined shape rather than a circular shape is formed in the mounting surface 55 of the fixed end 52 of the hinge shaft 50, and the head 63 is also formed in the recess 56. The corresponding shape is formed so that it can be seated. When the fixing part 62 of the hinge pin 60 is fixed by a predetermined fixing means at the other end of the hinge housing 20 after the head 63 is seated in the recess 56, the head 63 Is preferably installed to form a plane with the mounting surface 55 of the fixed end 52 of the hinge shaft (50).

In addition, it is preferable to install an E-ring 70 as a fixing means on the fixing portion 62 of the shaft 61 of the hinge pin 60 that finally passed through the hinge housing 20. This makes it easy to assemble and disassemble the hinge module without the need for a specialized jig.

Meanwhile, at least one spacer 80 may be interposed between the outside of the hinge housing 20 and the ring 70 to facilitate the operation of the hinge module 10. The spacer 80 may be a plastic material or a metal material, and may be anything that can minimize the frictional force between the ring 70 and the hinge housing 20.

Figure 4 is a perspective view of the combined hinge module according to a preferred embodiment of the present invention from one side, Figure 5 is a perspective view of the combined hinge module according to an embodiment of the present invention from the other side, a fully assembled hinge The module 10 is shown a hinge housing 20 and a fixed end 52 of the hinge shaft 50 protruding on the hinge housing. The fixed end 52 of the hinge shaft 50 is fixed to either the main body or the sub-body which rotates relatively. In this case, the hinge housing 20 is installed in the remaining part of the main body or the sub body. Therefore, the fixed end 52 is rotated together with the main body or sub body that rotates. FIG. 5 shows the rear of the hinge housing 20, in which the end of the penetrated hinge shaft 60 is fixed to the hinge housing 20 by the spacer 80 and the ring 70. .

Looking at the operation of the hinge module 10 according to the present invention with reference to FIG. 2, when the sub-body (120 of FIG. 1) of the terminal is opened, the hinge housing 20 is fixed on the main body (110 of FIG. 1) Hinge shaft 50 is rotated about. The hinge cam 30 is pushed back toward the rear portion (B direction) in the receiving portion 21 of the hinge housing 20 by being pushed by the ridge 53 of the rotating hinge shaft 50. At this time, the hinge spring 40 is stored a constant restoring force (force pushing the hinge cam in the hinge shaft direction). Thereafter, when the user opens the sub body more, the ridge 53 of the hinge shaft 50 rotates at an angle and engages the bone 33 of the hinge cam 30 again. This is because the restoring force stored in the hinge spring 40 is provided to the hinge cam 30. At this time, since the ridge 53 and the valley 33 are formed in a conical shape converging at one point with respect to the axis A, the ridge 53 and the bone 33 are prevented from rotating arbitrarily after being interlocked. . On the other hand, when closing the sub-body of the terminal (folding) also by performing the operation as described above to the reverse operation of the terminal can be performed smoothly.

Apparently, there are many ways to modify these embodiments while remaining within the scope of the claims. In other words, there may be many other ways in which the invention may be practiced without departing from the scope of the following claims.

Since the hinge module according to the present invention uses this ring as a fixing means, it can be easily assembled and disassembled without a specialized tool such as a jig, and has a separate hinge pin separated from the hinge shaft and the hinge cam, so that the terminal is frequently used. Damage to the hinge shaft due to the opening and closing operation can be prevented. In addition, since the hinge shaft and the hinge cam have a cone-shaped portion and a corresponding valley portion, the hinge shaft and the hinge cam can secure a holding force in a fully open or closed position of the terminal, thereby preventing malfunction.
