It is a top view which shows the state of the elastic member for sliding modules arrange | positioned obliquely so that the 1st guide part and the 2nd guide part formed in the inside may not become parallel.

Referring to FIG. 3 (a), the first rod 40 of the elastic member for sliding module moves left and right along the first guide portion formed in the body portion 65, and the second rod 45 is the body portion. It moves left and right along the 2nd guide part formed in 65. As shown to FIG. Since the first guide portion and the second guide portion are formed in parallel, the first rod 40 and the second rod 45 are moved in parallel along the first guide portion and the second guide portion, respectively.

When the first rod 40 and the second rod 45 respectively move as the elastic member 30 is mounted on the sliding module to contract or relax, each rod 40, 45 at the point where the elastic member is fully retracted. ) Exerts a force on the upper and lower sliders of the sliding module in the direction of the parallel arrow shown in FIG. At the point where the elastic member 30 mounted on the sliding module is fully retracted, the force applied by the first rod 40 to the slider and the force applied by the second rod 45 to the slider are in equilibrium and are perpendicular to the sliding direction. The point is made to be made, the point where the force of the elastic member 30 is not applied in the longitudinal direction in which the sliding module is sliding.

Accordingly, the elastic member for the sliding module, in which the first guide portion and the second guide portion formed in the body portion 65 are disposed in parallel, has the first rod 40 of the elastic member in the sliding operation at the point where the elastic member is fully contracted. ) And the force applied to the slider by the second rod 45 are in equilibrium with each other and become perpendicular to the direction of the force and the sliding direction, causing a point at which the sliding module stops without sliding.

Referring to FIG. 3B, the first guide portion and the second guide portion, which are the movement path of the first rod 40 and the movement path of the second rod 45, are arranged obliquely so as not to be parallel to each other. The first rod 40 according to the present invention moves left and right along the first guide portion, and the second rod 45 moves left and right along the second guide portion.

When the first rod 40 and the second rod 45 move left and right, respectively, as the elastic member for the sliding module is mounted on the sliding module and contracted or relaxed, the respective rods 40, 45) exerts a force on the upper and lower sliders of the sliding module to which the elastic member is mounted in the direction of the arrow shown in Fig. 3 (b) so as not to be parallel to each other.

The force applied to the slider and the force applied to the slider by the second rod 45 are not balanced with each other. Therefore, the elastic member for the sliding module according to the present invention can solve the problem that the sliding module stops without sliding by applying a force in one direction even at the point where the elastic member is contracted to the maximum.

Figure 4 (a), (b) is a cross-sectional view showing a state in which the body portion and each rod is coupled when the elastic module for sliding module according to the present invention shrinks or relaxes.

Specifically, Figure 4 (a) is a cross-sectional view showing a state in which the elastic member for the sliding module according to the present invention is relaxed, Figure 4 (b) is a state in which the elastic module for sliding module according to the present invention is in a contracted state It is sectional drawing to show.

Referring to FIGS. 4A and 4B, the elastic members for the sliding module according to the present invention have springs 50 and 55 respectively inserted into insertion holes of the first guide part and the second guide part formed in the body part 60. And insert spring inserting rods 41 and 46 formed in the first rod 40 and the second rod 45 into the springs 50 and 55, respectively.

Accordingly, the elastic member for a sliding module according to the present invention has a body portion along the first and second guide portions formed on the body portion 60 when the elastic member is contracted or relaxed due to the external force in the lateral direction applied to the elastic member. The first rod 40 and the second rod 45 are inserted or protruded into and out of the 60.

When an external force in the left and right transverse directions is applied to the elastic member for sliding module according to the present invention, the first rod 40 and the second rod 45 is moved into the body portion 60, each rod The springs 50 and 55 are formed in the 40 and 45 so that the spring inserting rods 41 and 46 into which the springs 50 and 55 are fitted are pushed inward along the insertion holes of the guide portions formed in the body 60. 55), the overall length of the elastic member is reduced. (FIG. 4 (b))

When the external force in the left and right transverse directions for contracting the elastic member for sliding module according to the present invention is no longer applied, the first rod 40 and the second rod 45 are external to the body portion 60. Move to protrude. Therefore, the spring insertion rods 41 and 46, which were inserted into the insertion hole of the guide portion formed in the body portion 60, are pushed out by the restoring force of the springs 50 and 55. (FIG. 4A)

In addition, in order to prevent the first and second rods 40 and 45 from being completely released while moving to protrude out of the body portion 60 when the elastic member for the sliding module according to the present invention is relaxed, each rod 40 , 45, the fastening portions 42 and 47 are formed. The fastening portions 42 and 47 formed on the left and right side surfaces of the first and second rods 40 and 45 are made of hooks, and are formed in the interior of the body portion 60 at the time of maximum relaxation of the elastic member. It is engaged with the jaw and prevents each rod 40, 45 from being completely detached from the body portion 60.

5 (a), 5 (b) and 5 (c) are plan views illustrating a state in which the elastic member for sliding module according to the present invention is installed and operated in the sliding module.

Referring to FIG. 5, specifically, FIG. 5 (a) is a plan view of the upper slider 20 in an upward state, and FIG. 5 (b) is a state in which the upper slider 20 is located in the middle of the lower slider 10. It is a top view, and FIG.5 (c) is a top view of the state which lowered the upper slider 20. FIG. The operation of the elastic member 30 according to the operation of the sliding module will be described with reference to FIGS. 5A to 5C as follows.

The sliding module according to the present invention is an apparatus for opening and closing the receiver by moving up and down the receiver by being installed between the receiver unit provided with the LCD screen and the voice output unit of the sliding mobile phone and the communication unit provided with the key button and the voice input unit.

The sliding module is mounted on a flat plate-shaped lower slider 10, an upper slider 20 that slides up and down along the lower slider 10, and a lower slider 10 and an upper slider 20. Both ends are attached to each other, and the elastic member 30 which supports sliding of the upper slider 20 to the up-down direction is included.

The elastic member 30 is installed between the lower slider 10 and the upper slider 20. (In FIG. 5, the elastic member 30 appears to be installed on the upper slider 20, but this is for showing the movement of the elastic member 30 well, and is actually the lower slider 10, which is below the upper slider 20). And between the upper slider 20.)

The lower slider 10 of the sliding module according to the present invention is coupled to the receiver portion of the sliding cell phone, and the upper slider 20 is coupled to the call portion of the sliding cell phone. Of course, depending on the type of mobile phone may be combined in reverse.

Therefore, FIG. 6 (a) shows a state in which the handset of the sliding cellular phone is lowered to close the call part, and FIG. 6 (c) pushes the handset to the state where the call part is opened. On the other hand, rail shafts (not shown) are attached to left and right sides of the lower slider 10 so that the upper slider 20 smoothly moves up and down in a state in which the upper slider 20 is engaged with the lower slider 10.

In addition, a predetermined distance from one side of the left and right side surfaces of the lower slider 10 and the upper slider 20 is penetrated / recessed so that the fixing projections 43 and 48 of the elastic member 30 can be fitted. The fixing grooves are formed to face each other, and the fixing grooves 43 and 48 of the elastic members 30 coupled to the fixing grooves can rotate respectively according to the movement of the upper slider 20. 48) is preferably formed in a circular shape.

Referring to the operation of the elastic member according to the operation of the sliding module of the present invention.

In the closed state of the mobile phone according to the present invention (Fig. 6 (a)), when the user raises the receiver, the upper slider 20 descends along the lower slider 10, the upper slider 20 and the lower slider 10 ), The distance between the fixing grooves becomes narrow, and an external force is applied in the left and right transverse directions of the elastic member 30. Accordingly, the first rod 40 and the second rod 45 located on both sides of the elastic member are pushed into the body portion 60, respectively, and spring inserting rods 41 formed on the rods 40 and 45, respectively. , The spring 50, 55 fitted in the 46 is compressed to reduce the length of the elastic member.

In addition, since the user is resisted to raise the handset by the elastic force of the springs 50 and 55, the elastic force of the springs 50 and 55 can prevent the upper slider 20 from moving suddenly. The distance between the fixing grooves of the upper slider 20 and the lower slider 10 is shortest when an intermediate point, i.e. both fixing grooves are located on the same horizontal line, at which time the springs 50, 55 are maximally compressed. (FIG. 5 (b))

The elastic member 30 for the sliding module according to the present invention is the point where the springs 50, 55 are maximally compressed by arranging the first guide portion and the second guide portion formed in the body portion 60 so as not to be parallel to each other. The force exerted by the first rod 40 and the second rod 45 on the upper and lower sliders 10, 20 is not balanced. Therefore, at the point where the elastic member 30 is compressed at the maximum, the direction of the force exerted by the two rods 40 and 45 of the elastic member 30 and the direction in which the upper slider 20 slides along the lower slider 10 are perpendicular to each other. This becomes difficult to generate a dead point where the sliding operation of the sliding module stops.

In the sliding module according to the present invention, when the upper slider 20 is further lowered, the distance between the two fixing grooves gradually increases, so that the external force exerted in the lateral direction of the elastic member 30 is also reduced, so that the springs 50 and 55 The first rod 40 and the second rod 45 are moved to protrude out of the body portion 60 by the restoring force. Therefore, as the length of the elastic member 30 is extended, the upper slider 20 is completely lowered to open the receiver. (FIG. 6 (c))

Similarly, when the user descends to close the receiver while the receiver is open, the distance between the fixing grooves of the upper slider 20 and the lower slider 10 becomes narrow as the upper slider 20 moves upwards, so that the first rod ( 40 and the second rod 45 are pushed into the body portion 60 to compress the spring (50, 55) fitted to the spring insertion rod (41, 46) formed in each of the rod (40, 45) The length of the elastic member is reduced.

In addition, if the receiver is lowered continuously, the distance between the upper groove 20 and the fixed groove of the lower slider 10 is further increased again to decrease the strength of the external force, thereby reducing the strength of the spring 50, 55. The first rod 40 and the second rod 45 are moved to protrude out of the body portion 60 by the restoring force. Therefore, as the length of the elastic member 30 is extended, the upper slider 20 is fully raised to close the hydration part.

6 (a) to 6 (c) illustrate an embodiment to which the elastic member 30 according to the present invention can be applied. The elastic member 30 according to the present invention requires a member having an elastic force. Of course, the device can be applied without any limitation.

The elastic member for sliding module according to the present invention is formed so that the first guide portion and the second guide portion formed in the body portion 60, which is the path through which the rods 40, 45 move, are arranged at an angle, not parallel to each other, The force applied to the upper and lower sliders 10 and 20 of the sliding module is not balanced at the point where the elastic member is compressed to the maximum, so that the direction of the force of the elastic member and the sliding direction of the sliding module are perpendicular to each other. Therefore, it is possible to prevent the occurrence of a point where the operation of the upper slider is stopped.

Rods 40 and 45 positioned on the left and right sides of the elastic member to move in the transverse direction when the elastic member contracts or relaxes, and provide a plurality of elastic forces when the rods 40 and 45 move in the transverse direction.
