Description

ROUND SHAPED SLIDING MODULE HAVING THE CASING AS ONE BODY}

The present invention relates to a circular slide module having an integrated casing, and more particularly, a circular slide having an integrated casing mounted on a slide open / close personal portable communication terminal (hereinafter referred to as a 'mobile terminal') consisting of an upper housing and a lower housing. It is about a module.

In general, the portable terminal has a folding type opening and closing method from a straight bar type to a flip type, and has further evolved into a portable terminal of a slide type.

The slide open / close portable terminal includes a lower housing including a keypad and a microphone, an upper housing including a display and a speaker to perform a sliding operation, and a slide module interposed between each housing to perform a sliding operation. consist of.

As shown in FIG. 1, the slide module according to the related art is provided with first and second fixing bars 12 and 13 for fixing a lower housing of the portable terminal, and an upper housing of the portable terminal and a lower housing of the portable terminal. A sliding member 10 for sliding the sliding member 10; A support plate 20 fixed to the upper housing of the portable terminal and configured to support the sliding member 10; The sliding member 10 attached to the support plate 20 is fixed, and consists of a guide plate 30 is formed with a guide hole 32 for guiding the sliding of the sliding member 10.

The guide plate 30 has a rectangular parallelepiped shape in which one surface similar to the support plate 30 is opened. The guide plate 30 has a rectangular plane 31 having a guide hole 32 formed in a central portion thereof, and four planes having a predetermined height from the plane 31. It consists of vertical walls.

A ridge in which a portion of the leaf spring 11 between the first and second fixing rods 12 and 13 is raised to insert a ball 15 between the leaf spring 11 and the support plate 20. 14) is formed.

In addition, two holes 22 and 23 are formed on the bottom surface 21 of the support plate 20 to be spaced apart from each other, so that the ball 15 is caught when the slide member 10 is slid.

For example, when the ball 15 is caught in the holes 22 and 23, the user can feel a locking feeling of 'clicking', thereby allowing the user to slide the upper and lower housings of the mobile terminal by sliding. It is to be able to check the open and close state between them.

The supporting plate 20 is fixed to the upper housing of the portable terminal, and the first and second fixing rods 12 and 13 are fixed to the upper housing of the portable terminal by using the screws 16 and 17.

The conventional slide module is configured to perform a sliding operation in a state interposed between the upper and lower housings of the portable terminal.

However, the slide module according to the prior art divides the guide plate and the support plate having a rectangular cross-sectional shape in the form of disassembly and assembly. By fixing and assembling the support plate to the guide plate, the assembly work is very inconvenient and inefficient, or there is a disadvantage that a separate assembly jig is required.

However, in the slide module according to the related art, since the rectangular block-shaped sliding member moves straight inside the assembled guide plate and the supporting plate, unstable straight motion due to surface contact and line contact is likely to occur, and in particular, frequent assembly failure and assembly Sliding member is shaken according to the occurrence of the gap (tolerance) of the site, there is a disadvantage that it is very difficult to control the coupling tolerance.

In addition, the slide module according to the prior art, as the coupling relationship between the guide plate and the support plate assembled after a long time of use becomes weaker, the sliding member is more shaken or oscillated during the sliding operation, thereby affecting the stability of the sliding operation. As a result, the operability and sophistication of the opening and closing are relatively inferior, and durability of the slide module is inferior.

Accordingly, an object of the present invention for solving the above-mentioned problems is to provide a carrier with a relatively increased cross-sectional area in a circular shape, and an integral casing which stably surrounds such a carrier, so that the linear motion is increased according to the relatively increased friction or sliding resistance. It is to provide a circular slide module having an integrated casing that can prevent the shake of the carrier and ensure a straight stability, can reduce the assembly work, and increase the product durability.

It is a perspective view for demonstrating. 4 is a cross-sectional view of the line AA 'or B-B' shown in FIG. 2, and FIGS. 5A and 5B are cross-sectional views for explaining the operation relationship of the circular slide module having the integrated casing shown in FIG. .

As shown in Figure 2 or 3, the overall configuration of the main body 100 of the present invention is all six parts, the ilke casing 110, the carrier 120, the spring 130, the rolling member 140 The first cap 150 and the second cap 160 are included.

The integrated casing 110 processes a high-strength metal material having abrasion resistance against frictional reliability and point contact of the rolling member 140 of the carrier 120 through a conventional extrusion manufacturing method. In the conventional extrusion manufacturing method, the extrusion casing is continuously extruded in the axial direction (length direction) through the extrusion die corresponding to the cross-sectional shape of the integrated casing 110 described above, and then cut by a predetermined length to form the integrated casing 110 of the present invention. Mass production is possible.

Of course, the integrated casing 110 can be produced by a die casting method, such as aluminum alloy.

The ilke casing 110 has a sliding friction portion 111 extending in the axial direction through the circular hole to prevent the separation of the carrier 120 moving to the part that serves as the overall guide of the slide.

The slit 112 is opened in the shape which cut about 1/4 arc part of the circular shape in the sliding friction part 111, and is extended in the direction corresponded to an axial direction.

Various bosses 121, 122, and 123 of the carrier 120 protrude out of the main body 100 through the sliding friction part 111 and the slit 112.

On the opposite side of the slit 112 is for positioning the carrier 120, the first binding hole 113 of the bottom dead center and the second binding hole 114 of the top dead center is formed to pass through. Here, the first binding hole 113 and the second binding hole 114 locks the rolling member 140 by the elastic force or the elastic repulsive force of the spring 130.

The carrier 120 is a part having a structure of actual movement in the slide module, the overall shape of which is inserted into the sliding friction portion 111 and the slit 112 of the integrated casing 110 so as to slide, 1 / of a circular cross section. 4 has a bar shape cut off. The upper surface of the carrier 120 has a central boss 133 protrudingly formed, and a plurality of fixed bosses 122 and 123 protruded from both sides of the central boss 121 by a predetermined interval. Here, the central boss 133 forms an insertion hole opened downward for accommodating the spring 130 and the rolling member 140, and the fixed bosses 122 and 123 are a tab type, which is a portable terminal. A screw hole is formed to be coupled to a screw (not shown) through the bolt hole of the upper housing or the lower housing. The role of the carrier 120 is largely divided into a sliding function and a locking function (locking role) as described below, and a conventional slide type mobile terminal (handset) fixing function.

In the present description, the sliding of the carrier 120 is a straight line between the first binding hole 113, which is the bottom dead center of the integrated casing, and the second binding hole 114, which is the top dead center, determined as a basic role of the sliding type mobile terminal. Movement distance value]. At this time, the frictional force acts as much as the pressing force of the spring 130 of the rolling member 140 is characterized in that the sliding operation proceeds.

The spring 130 is a compression type spring, which is assembled with the rolling member 140 in the insertion hole of the carrier 120 and serves to push the rolling member 140. This provides an appropriate friction value during the slide and provides an elastic force that pushes the rolling member 140 into the first binding hole 113 or the second binding hole 114 of the integrated casing 110. That is, the rolling member 140 provides a source of locking force that is locked to the first binding hole 113 or the second binding hole 114.

The rolling member 140 has a diameter of a ball slightly larger than that of the first fastening hole 113 or the second fastening hole 114 of the unitary housing 110 or the shape of a steel ball, and when the slide is operated. Part of the rolling member 140 is released to the first binding hole 113 or the second binding hole 114 by giving an appropriate friction value. Of course, the rolling member 140 is manufactured using a high-strength material for securing wear resistance by point or line friction with the integrated housing 110.

The first cap 150 is a part that prevents the carrier 120 from being separated in the axial direction from the unitary housing 110. The first cap 150 has a screw hole 151 for fixing the entire slide module to the mobile terminal or the handset. It has a bracket-like portion and the insertion portion 152 to include.

Since the insertion portion 152 of the first cap 150 has a slightly larger cross-sectional area while corresponding to the cross-sectional shape of the sliding friction portion 111 of the integrated housing 110, one end end of the sliding friction portion 111 is provided. It is secured in the form of interference fit to ensure the reliability of being tightly coupled.

The second cap 160 may be formed in a shape substantially the same as that of the first cap 150, and in particular, the plate-shaped bracket shape portion 161 and the insertion portion 162 fixedly fixed to the coupling portion of the housing of the mobile terminal. ), And the insertion portion 162 is coupled to the other end of the sliding friction portion 111 in a similar manner to the first cap 150.

The first cap 150 and the second cap 160 prevent the carrier 120 from being separated from both ends of the axial direction of the unitary housing 110, and the entire slide module is fixed to the mobile terminal or the handset. In charge of.

The main body 100 of the present invention formed of such a component is divided into a sliding function of the handset and a locking function after sliding of the handset.

-Sliding function

The sliding module, that is, the basic operation of the handset operation, the slide module according to the opening and closing operation of the present invention of the handset is to move up and down straight.

The axis of the linear motion (sliding) is determined in the unitary casing 110 of the modular structure. If the linear motion is performed by the carrier 120, the value of the acting force is friction between the carrier 120 and the integrated casing 110, friction between the rolling member 140 and the integrated casing 110, Determined by the weight (weight) of the housing of the handset being pushed (or closed), this operation is purely by manual force (push by finger).

This slide function is the most important function of measuring the basic reliability of the handset and is determined by the structure and material selection that can maintain the reliability.

Locking function

The point at which the handset is fully open (at the point of reaching the position of the second fastening hole 114, which is the top dead center point), and the point at which the slide handset is completely closed after the sliding operation. At the time of reaching the position of the first binding hole 113, which is a point, temporary locking is performed, and when a predetermined amount or more of the force is applied in the sliding direction or the opposite direction thereof, the locking is released again to enable the sliding operation.

The locking of the main body 100 of the present invention is basically a rolling member 140 that is pushed by the spring 130, and the first and second binding holes 113, 114 of the rolling member 140 is pulled out and locked. Is performed by.

Rolling member 140 is a hole of a certain size in the center of the carrier 120 is inserted into the spring 130 first to put the rolling member 140 thereon to give a force in the direction perpendicular to the sliding direction It is.

The first and second fastening holes 113 and 114 penetrate the bottom surface of the integrated casing 110 in a direction perpendicular to the sliding direction, and are slightly smaller than the rolling member 140 to process the rolling member 140. It is designed to prevent deviation.

As shown in an enlarged view in FIGS. 4, 5A, and 5B, the integrated casing 110 having the first binding hole 113 or the second binding hole 114 formed therein is different from the supporting plate and the guide plate of the related art. Since the sliding friction portion 111 on the smooth inner circumferential surface is free of defect grooves, defect gaps, and the like, it provides a structure resistant to vibration and noise.

In addition, the integrated casing 110 is formed to extend in the axial direction a plurality of reinforcing beams 115 and 116 integrally protruding on both outer surfaces, thereby exhibiting a more stable supporting force.

In particular, the outer surface of the reinforcing beams 115 and 116 and the integrated casing 110 in the space 117 between the reinforcing beams 115 and 116 is used as a fixing means fixed to the housing of the mobile terminal or the handset, Formed in the housing By being able to fasten in the shape of the fixing projections (60), etc., it provides a more stable fixing force and easy assembly environment.

The sliding friction part 111 generates frictional force to secure the stability of the sliding operation in the axial direction through the circumferential surface contact with the carrier 120, but combines the carrier 120 with a predetermined engagement clearance, thereby smooth sliding operation. Can be performed simultaneously.

Accordingly, the sliding friction part 111 may prevent the carrier 120 from being separated during the sliding operation and the locking operation of the carrier 120, or may be guided through the relationship between the slit 112 and the various bosses 121. As a result, the sliding operation in the axial direction of the carrier 120 may be smoothly performed.

In addition, since the integrated casing 110 substantially surrounds the circular bar-shaped carrier 120 in a circular manner, the sliding casing 110 in the axial direction reduces vibration or shaking in comparison with a conventional plate sliding member. Giving effect.

The locking operation principle of the carrier 120 described with reference to FIGS. 5A and 5B is a rolling member that is pushed into the insertion hole 129 of the carrier 120 by the bottom surface of the integrated casing 110 when sliding. 140 corresponds to the size of the second binding hole 114 or the first binding hole 113 in the vertical direction by the elasticity of the spring 130 while meeting the second binding hole 114 or the first binding hole 113. Rolling member 140 is moved vertically by the height of the diameter of the rolling member 140 to be locked in the second binding hole 114 or the first binding hole 113.

Again, when applying a force greater than the elasticity of the spring 130 in parallel with the sliding direction, the rolling member 140 slides out of the second fastening hole 114 or the first fastening hole 113 again the carrier 130 It is inserted into the side to make sliding or stop.

The present invention configured as described above is a passive slide type, which provides a carrier having a relatively circular cross-sectional area and an integrated casing which stably surrounds such a carrier, so that the linear slide is driven by the increased friction and sliding resistance. There is an advantage to provide a circular slide module having an integrated casing that can prevent the shaking of the carrier during the movement and ensure the straight stability.

In addition, the circular slide module having an integrated casing of the present invention, according to the provision of the integrated casing, can relatively reduce the assembly work, there is an advantage that can increase the product durability.

In addition, the circular slide module having an integrated casing of the present invention provides a high-touch operability according to opening and closing in the first and second binding holes while smoothly and accurately transferring the upper or lower housing for the portable terminal in the form of a bar. This design can be applied to the design of the module simply by applying the present invention to complete the excellent housing sliding opening and closing structure, so that the universality of the new type of the slide module, as well as the functionality capable of semi-automatic sliding operation.

In addition, since the circular slide module having an integrated casing of the present invention is formed to extend in the axial direction integrally projecting reinforcing beams on both outer surfaces of the integrated casing, it can provide a structure resistant to vibration and noise, In addition, as it is used as a fixing means fixed to the housing of a mobile terminal or a handset, there is an advantage of providing a more stable fixing force.

In addition, the preferred embodiment of the present invention is disclosed for the purpose of illustration, those skilled in the art will be able to make various modifications, changes, additions, etc. within the spirit and scope of the present invention, such modifications and modifications are in the scope of the utility model registration claims below It should be seen as belonging.
