Description

Spring module of slide type terminal

The present invention relates to a spring module of a slide type terminal, and in particular, the slide type of the improved structure to improve the durability of the spring itself while smoothly made by the spring of the compact structure withdrawal opening and closing operation of the slide type terminal It relates to a spring module of the terminal.

Recently, a mobile phone has a mainstream slide type terminal which slides a slide body by a predetermined length in the longitudinal direction of the main body with one hand. Such a slide type terminal is roughly classified into a main body provided with a dial keypad, a slide body slidably coupled to an upper portion of the main body, and a slide body provided with an LCD screen, and a slide unit coupling the slide body to the main body by a slide method. .

In addition, various types of spring modules are employed to maintain the open and closed states of the slide body of the slide type terminal. The open state of the slide body refers to a state in which the slide body is drawn out in the longitudinal direction of the main body, and the closed state of the slide body refers to a state in which the slide body is folded back in the longitudinal direction of the main body.

According to the spring module having such a structure, in the state in which the slide body is opened to one side of the main body, two levers protrude to both ends of the spring housing by the force of the coil spring, and the slide body is pushed to one side of the main body to maintain the open state. At the moment when the slide body is pushed back into the main body, the two levers are pushed in from both ends of the spring housing and the spring is compressed, Again, the two levers are unfolded by the force of the coil spring, allowing the slide body to be folded back into the main body. Of course, even when the slide body is pulled out of the main body and opened when the slide body is folded, the two levers are pushed into the spring housing and the coil spring is compressed and the two levers are opened when the inflection point is crossed. The force of the coil spring allows the slide body to be pulled out back into the main body to remain open.

As shown in FIG. 1, the slide module for mobile phones according to the prior art (published in Utility Model Registration No. 2004-8463) according to the prior art is a display unit for a main body 2 equipped with a keypad 1. In the slide module (5) of the terminal for slidingly opening and closing the slide body (4) is mounted (3), the fixing piece (6) is mounted to the coupling groove of the main body (2) and the guide rail is formed on both sides and The slide piece 7 is mounted to the coupling groove of the slide body 4 and the guide piece corresponding to the guide rail is formed to be slidably moved with respect to the fixing piece 6, and one end is fixed to the fixing piece 6. The other end is fixed to the slide piece 7, and includes the compression coil spring 8 which slides the slide piece 7 with respect to the fixed piece 6 by elastic force.

In the slide module of the conventional terminal, one compression coil spring 8 is used to slide the slide piece 7 with respect to the stationary piece 6. When the mobile phone is repeatedly opened and closed for a long time, the elastic restoring force of the compression coil spring 8 is lowered, so that the opening and closing operation of the slide body 4 with respect to the main body 2 is not smooth.

When the elastic restoring force of the compression coil spring 8 is lowered, the slide body 4 sliding with respect to the main body 2 is completely opened, or is caused by external impact or the like even after full close. Since the slide body 4 can be easily flowed with respect to the main body 2, there is a problem of low reliability from the user.

In addition, by fixing both ends of the compression coil spring (8) to the slide piece (7) and the fixing piece (6), respectively, the compression coil spring (8) when the slide body (4) is repeatedly opened and closed with respect to the main body (2). Since the load is applied directly and repeatedly to the fixed portion of), the durability of the fixed portion of the compression coil spring 8 has a problem.

In addition, Korean Patent Application Publication No. 10-2008-0084444, published on September 19, 2008 as a prior art, discloses a configuration in which a slide body is pulled out or slide-in from a main body using two torsion springs.

However, the patent has a problem that the space occupied by the slide structure is increased due to the connection structure of the main body and the slide body by using two springs and torsion springs.

An object of the present invention is to solve the problem of the spring module in the conventional slide-type terminal, more specifically, the slide body smoothly and elastically with respect to the main body with stability and durability required even in the inner space of the narrow terminal It is an object of the present invention to provide a spring module of an improved slide type terminal which is slidable and has a remarkably improved number of repetitions of compression and decompression operations of the spring, and thus has a more durable structure.

According to the present invention for achieving the above object, in the slide type terminal is provided with a slide body to open and close in the longitudinal direction on the main body, the slide body is switched to the state that is drawn out or received in one direction of the main body And a slide piece 14 coupled to the slide body, a fixed piece 12 coupled to the main body, and an elastic member 18 connected to the fixed piece 12 and the slide piece 14. The elastic member 18 includes a coil-shaped elastic portion 15 formed in a snail shape in which a small diameter coil portion 15a having a relatively small diameter and a large diameter coil portion 15b having a relatively large diameter are continuously connected to each other. And a pair of

wire rods

16 and 17 which are integrally connected to the coil-shaped elastic portion 15 and connected to the fixing piece 12 and the slide piece 14 via hinges, respectively. Characteristic The spring module of the slide type portable terminal is provided.

In the spring module of the slide type terminal according to the present invention, when the slide body is pushed upward with respect to the main body and operated to push the slide piece upward with respect to the fixed piece, the slide body is half open with respect to the main body. In the half-open state, the elastic member, which is a main part, has a structure in which a coiled elastic part is formed in a snail shape with a central part subjected to a force, so that the left and right wire parts of the elastic member face each other in the direction of the reference center line in the vertical direction (ie, facing each other). Direction), and the bending force acts on the coil-shaped elastic part formed in the snail shape, and the bending force acting on the coil-shaped elastic part in the snail shape acts in the arc-like direction, but the bending force is Since it acts directionally along the coil-shaped elastic portion, the balance of force is maintained when the bending force is applied to the elastic member In this case, the elastic member may have a longer lasting effect on the repeated bending force release and the bending force release action. In other words, the number of times of acting on the repeated bending force and the bending release force by the snail-shaped coil-shaped elastic part, which is the core of the elastic member, can be significantly increased, compared with the prior art. Will be able to increase even more.

In other words, both ends are fixed to the fixed piece and the slide piece coupled to the slide type terminal, so that the central portion of the elastic member for exerting the elastic force for sliding the slide piece with respect to the fixed piece is subjected to the maximum force, resulting in structural weakness. . By the way, by forming the coil-shaped elastic portion forming the central portion of the elastic member to have a snail shape to distribute the force generated in the central portion of the elastic member, it is possible to prevent the phenomenon that the elastic member is easily broken due to fatigue limit, Due to these factors, the elastic member repeatedly increases the number of times the bending force is applied and the bending force is released.

In addition, another embodiment of the present invention is a pair of coil-like elastic portion that is connected in series with the elastic member as the main portion, and each of these coil-like elastic portion is integrally connected to each other around the hinge and the fixed piece and the slide piece It has a structure including a pair of wire rods connected to each other, and can double the force of the portion subjected to the bending stress by the two coil-like elastic portion, and also the load distribution of the bending force can be double, elastic member It has the effect of doubling its life.

In addition, the wire rod portion is fixed to the fixed piece and the slide piece, respectively, in the state that the coil-shaped elastic portion of the elastic member is accommodated in the case, to prevent the deformation of the elastic member accommodated in the case when the slide body of the slide type terminal to one side of the main body Therefore, the elastic force of the elastic member can be maintained in the initial state. In other words, when the bending force is applied to the elastic member, the case is supported by the case in the up and down position to prevent the warping phenomenon, so that the elastic force of the elastic member can be reliably maintained in the initial state.

And, since the coil-shaped elastic portion of the elastic member formed of a wire or plate is wrapped by the case, it is possible to minimize the space between the fixed piece and the slide piece, it is possible to slim the overall thickness of the terminal. In particular, the coil-shaped elastic portion of the elastic member is formed in the form of a snail in which the small diameter coil portion having a relatively small diameter and the large diameter coil portion having a relatively large diameter are continuously connected, and the small diameter coil portion is configured to be accommodated at an inner position of the large diameter coil portion. Since the vertical thickness of the coil-shaped elastic portion can be minimized, the vertical thickness of the slide-type terminal can be realized as slim as possible.

In addition, by accommodating the elastic member having a snail-shaped coil-like elastic portion in the assembled case, and by fixing both ends of the elastic member to the fixed piece and the slide piece of the slide-type terminal, the work time for assembling the module is shortened It can improve the work efficiency.

This cover 22 is also injection molded such that each part is integrated.

Therefore, the elastic member 18 is interposed between the cover 22 and the base 20, and the coupling pieces 19 of the rocker 21 and the base 20 of the cover 22 are coiled of the elastic member 18. The engaging jaw 21a of the rocker 21 and the engaging jaw 19a of the engaging piece 19 are engaged in one-touch manner with each other while being fitted inside the mold elastic part 15, and at the same time the cover 22 When the hook 24 of the base 20 is coupled to engage with the locking groove 25 of the base 20, the coil-shaped elastic portion 15 of the elastic member 18 is accommodated in the case 23 and supported, and at the same time, the elastic member The left and

right wire rods

16 and 17 of 18 may have a structure exposed to both ends of the case 23, and at the same time, the cover 22 may be prevented from rotating relative to the base 20. Will be.

Of course, the coiled elastic portion 15 of the elastic member 18 is supported by the locker 21 of the cover 22 and the coupling piece 19 of the base 20 which are engaged with each other so as not to flow. The upper and lower parts of the mold elastic part 15 can be supported by the case 23.

The case 23 shown in FIGS. 11 and 12 is more suitable for accommodating the elastic member 18 shown in FIG. In the elastic member 18 shown in FIG. 10, the elastic member 18 may be configured as shown in FIG. 10. In the elastic member 18 shown in FIG. 10, the straight connection portion 15c in the center may have a small diameter. It is comprised in the shape continuously connected to the coil part 15a. In the elastic member 18 shown in FIG. 10, it is preferable that two vertically symmetric small diameter coil portions 15a have a structure in which they are connected to each other by a linear connection portion 15c.

Therefore, when the elastic member 18 of FIG. 10 is received between the base 20 and the cover 22 and the base 20 and the cover 22 are engaged with each other in the same manner as above, the elastic member 18 It is possible to take a structure in which the elastic member 18 is accommodated in the case 23 in a state in which the linear connecting portion 15c of is fitted into the linear cutout 21b formed in the bottom rocker 21 of the cover 22.

On the other hand, the case 23, the base 20 and the cover 22 may be assembled by a one-touch coupling method of the rocker 21 and the coupling piece 19, but the base 20 and the cover 22 are fused It is also possible to assemble each other in a (for example, high frequency fusion) method.

At this time, the hinge piece 38 press-cocked at the ends of the

wire parts

16 and 17 constituting the elastic member 18 is rotatably cocked to the fixed piece 12 and the slide piece 14, respectively. For this reason, the slide piece 14 can be moved with respect to the fixed piece 12 by the elastic force of the elastic member 18 in a sliding system.

Of course, the engaging

ring portions

16a and 17a formed at the distal end portions of the

wire rod portions

16 and 17 are inserted around the substantially cylindrical hinge piece 38, and the hinge piece 38 is fixed to the fixed piece 12 and the slide. By rotatably caulking on the piece 14, the left and

right wire parts

16 and 17 of the elastic member 18 can be rotatably coupled to the fixed piece 12 and the slide piece 14, respectively.

On the other hand, as shown in Figure 4b, the hinge piece 38, which is injection-molded inserts at the ends of the wire member (16, 17) main part of the elastic member 18 to the fixed piece 12 and the slide piece 14 It is also possible to take a configuration to fit the coupling holes 39 formed in each case, in this case, by combining the spring module prefabricated, it is possible to improve the workability due to the reduction of working time. Of course, even in such a case, the slide piece 14 can be slid to the fixed piece 12 by the elastic force of the elastic member 18.

In this case, the base 20 and the cover 22 forming the case 23 may have a structure that is injection molded and fitted, and the base 20 and the cover 22 forming the case 23 are press-molded. It may have a structure that is caulked.

According to the present invention having such a configuration, as shown in FIG. 14A, when the slide body is fully closed with respect to the main body of the slide type terminal, the slide piece 14 is caused by the elastic force of the elastic member 18. Since the pressing against the fixing piece 12, it is possible to prevent the slide body from flowing with respect to the main body when the slide body of the terminal is completely closed.

When the slide piece 14 is pushed upward in order to slide and open the slide body and the slide piece 14 from the lowest point position of the fixed piece 12 to the highest point by the user in a state where the slide body is closed as shown in FIG. 14A. , Is moved to the state shown in FIG. 14B.

On the other hand, as shown in FIG. 14C, when the slide body 13 is fully open with respect to the main body, when the slide piece 14 is continuously pressed by the user and pushed upwards, As the force equilibrium state of the elastic member 18 is lost, the direction of the force is generated. For this reason, even when the user no longer presses the slide piece 14, the slide piece 14 is slid by the elastic restoring force of the elastic member 18, and is moved to the highest point. At this time, the slide piece 14 is pressed against the fixed piece 12 by the elastic force of the elastic member 18. As a result, when the slide body of the slide type terminal is completely opened, the slide body may be prevented from flowing with respect to the main body.

If the slide body of the slide-type terminal is pushed back into the main body to be in a closed state, the above-described process may be reversed.

In the case of the present invention, if the slide body is pushed upward with respect to the main body to push the slide piece 14 upward with respect to the fixed piece 12, as shown in Fig. 14B, the slide body with respect to the main body Is half open, and the elastic member 18 has a structure having a coil-shaped elastic portion 15 formed in the shape of a snail in a central portion subjected to a force, and bending to the elastic member 18. Since the force equilibrium state is maintained when stress is applied, the main feature is that it can exert a considerable effect on the extension of the service life.

In other words, the left and

right wire rods

16 and 17 of the elastic member 18 are rotatably connected to the fixed piece 12 and the slide piece 14 via the hinge piece 38, respectively, to slide the slide type terminal. As the body is pushed upward with respect to the main body, the slide piece 14 is simultaneously pushed upward with respect to the stationary piece 12, and at the same time, the left and

right wire parts

16 and 17 of the elastic member 18 are moved up and down. Direction is bent in the direction of the reference centerline (ie, the direction facing each other), and this bending force acts on the coiled elastic part 15 formed in the snail shape, and the coiled elastic part 15 in the snail shape. The acting bending force acts in the arc-like direction as shown by the arrow, and since this bending force acts directionally on the coil-shaped elastic portion 15 of the snail shape, the equilibrium state of the force when the bending force acts on the elastic member 18 Can be retained, whereby the elastic member 18 For repetitive bending forces and bending forces acting release action will have an effect that can withstand more long. That is, the number of times of acting on the bending action force and the bending release force repeated by the snail-shaped coil-like elastic part 15, which is the core of the elastic member 18, can be significantly increased, compared with the conventional art. The service life of the portable terminal can be further extended.

Structure is provided, the bending stress during the action of the bending force of the elastic member 18 is uniformly dispersed by the upper and lower large diameter coil portion 15b, the bending stress is once again by the intermediate small diameter coil portion 15a Since the dispersion, the dispersion effect of the bending stress is greatly increased compared to the conventional one, and ultimately, the life extension effect of the slide type terminal itself can be considerably increased.

In addition, as shown in FIG. 9A, there may be only one small diameter coil unit 15a as described above, and may be symmetrically paired above and below the horizontal center line C-C based on the side surface. In this case, the two small-diameter coil portions 15a are symmetrically formed above and below the horizontal center line on the side, and at the same time, the two large-diameter coil portions 15b are provided. When the two small diameter coil portions 15a and the two large diameter coil portions 15b are symmetrically shaped, the force dispersion effect of the bending stress acting on the

elastic members

18 and 30 can be doubled. The effect of further extending the life of the mobile terminal can be obtained.

right wire parts

16 and 17 are supported up and down when bending stress of the elastic member 18 is applied, the

elastic members

18 and 30 themselves are bent with directivity without twisting up and down. Or bend release effect, which means that the operating reliability of the elastic member 18 itself can be increased to further improve the product reliability of the slide type terminal itself.

wire rods

16 and 17, which are other main portions of the elastic member 18, are formed in a mountain shape by the intermediate

bent portions

wire rod portions

16 and 17 may be increased. There is an effect to further increase the force to withstand, thereby increasing the durability of the elastic member 18 itself, and furthermore, it is possible to further reduce the left and right width of the elastic member (180), It is also possible to implement the ruler and the width smaller. Importantly, by reinforcing the left and right

wire rod portions
