A cover 2 having a built-in circuit board and having various operation buttons and a cover 2 which is hinged by the shaft connecting portion 3 and the rotating portion 4 of the main body 1 to rotate and open and close The mobile phone 100 is provided.

The cover opening device applied to the mobile phone 100 is an operating means 150 directly installed in the housing 13 or the rotating part 4 via the operating means 150 in the rotating part 4 of the cover 2. and;

It is provided in one position of the main body 1 is composed of a button (5) connected to the operating means 150 so as to control the operating means 150 is a straight line of the button (5) by the operation of the button (5) The operating means 150 receiving the movement is configured to switch to the rotational movement by the torsional operation so that the cover 2 is opened.

The actuating means 150 is a torsional compression spring inserted into the receiving groove 151 formed in the housing 13 to have a restoring force and a torsional torque by compression, and an operator 8 located in front of the torsional compression spring. And a clutch 10 engaged with the operator 8 in front of the operator 8.

Spring arms (16, 17) formed on both sides of the torsional compression spring is the inner wall (14) or projection (28) of the housing 13, the inner wall (14) or projection (28) of the cap and the operator (8) Inserted to be twisted into the locking means 152, such as holes, grooves, slots formed in the projection (27) to have the maximum torsional torque when the cover (2) is folded.

Both sides of the torsional compression spring can be maintained in a stable state by protrusions 27 and 28 formed to protrude from the inner wall 14 of the operator 8 and the housing 13 or the inner wall 14 of the cap. Of course, the torsional efficiency of the torsional compression spring when the cover 2 is rotated to be maximized.

The operator 8 fixing one side of the torsional compression spring is located on the side of the housing 13 to compress the torsional compression spring by means of a fixing means 153 such as a pin or screw to fix the torsional compression spring to the housing 13. The clutch 10 is engaged with the clutch 10 to be interrupted.

The clutch 10 has an opening and closing slope 12 and a coupling groove 11 and a torsion plane 29 or a torsional compression slope 53 formed to allow entry and exit of the engaging projection 9, and the The operator (8) is formed with a engaging projection (9) to be engaged with the opening, closing slope 12 of the clutch 10 when the cover (2) is closed.

When the cover 2 is closed, the open and closed slopes 12 coupled with the engaging protrusion 9 have an inclination angle such that the restoring force of the compression of the torsion compression spring is greater than that of the torsional compression spring. 2) should be kept closed.

The torsion plane 29 of the clutch 10 is formed to increase only the torsional force of the torsion compression spring when the cover 2 rotates to the closed position by acting with the engaging projection 9.

Then, the torsional compression inclined surface 53 is formed to act together with the engaging projection 9 to increase the torsional force of the torsional compression spring and the axial compression force when the cover 2 rotates to the closed position.

The clutch 10 and the operator 8 as described above are the clutch 10 and the operator 8 having the clutch 10 and the operator 8 or the torsional compression slope 53 with the torsion plane 29. You can select and apply either.

When the cover 2 is switched from the closed position to the open position, the restoring force of the rotational direction held in the closed position allows the cover 2 to be opened.

The actuator 8 may be coupled to the connecting shaft 7 penetrating the center of the clutch 10 by a fixing means, or the connecting shaft 7 may be integrally formed on the actuator 8.

The connecting shaft (7) is coupled to the button (5) inserted into the button hole (6) formed in a non-rotating shape in the shaft connecting portion (3) by the button (5) the operator (8) from the clutch (10) ) Is released to rotate the housing 13 by the restoring force of the torsion so that the cover 2 coupled with the housing 13 can be opened.

The button (5) and the button hole (6) forms a spline on the outer surface to allow only linear movement in the direction of the connecting axis (7), oval, rectangular, cut both sides of the ellipse, circular both sides or three sides cut Any shape can be applied as long as it is impossible to rotate in one shape and can only linearly move the operator 8 in the axial direction.

Then, when the cover 2 rotates from the open position to the closed position, the spring arm 16 of the torsional compression spring rotates idle for a certain angle to have a torsion torque so that the torsional compression spring can be relatively relatively compared to the restoring force due to the torsion. Means for increasing the restoring force by compression so that the cover 2 is strengthened in the closed position so that the cover 2 is not easily opened even by an external impact or the like;

In order to fix the spring arms 16 and 17 of the torsional compression spring, the protrusions 27 formed on the operator 8 or the operator 8 and the inner wall 14 or the inner wall 14 of the housing 13 are formed. The revolving groove is further formed in the locking means 152 such as the grooves, holes, and slots formed in the projections 28, the inner wall 14 of the cap, the projections 28, and the like.

In the present invention, the torsional compression spring is characterized by being configured by separating the torsion bar 270 made of a material having elasticity with the compression spring 15-1 or a shape memory alloy.

Looking at the configuration of the present invention in detail;

The compression spring 15-1 is installed between the operator 8 mounted inside the housing 13 and the inner wall 14 of the cap 13 fixed to the inner wall 14 of the housing 13 or the housing 13. When the cover 10 rotates from the open position to the closed position, the clutch 10 retains a predetermined compressive force by the fixing means 153 when the clutch 10 is composed of the torsion plane 29.

And, when the clutch 10 is composed of a torsional compression inclined surface 53, the compression force is increased by the torsional compression inclined surface 53.

The torsion bar 270 penetrates the center of the compression spring 15-1, and one side is fixed to the protrusion 27 formed on the operator 8, and the other side is the inner wall 14 or the housing of the housing 13. It is fixed with the piston 271 inserted in the cylinder 272 formed in the inner wall 14 of the cap fixed to (13).

The torsional force of the torsion bar 270 is increased when the cover 2 rotates from the open position to the closed position so as to be maximum in the closed position.

The piston (271) is impossible to rotate in the cylinder 272, and the ellipse, square, pentagonal, circular both sides so that only the linear reciprocating movement in the direction of the connecting shaft (7) when the button (5) operation and the cover (2) rotates It is made into the shape which can not be rotated like the shape which cut off.

On the contrary, the piston 271 of the torsion bar 270 is inserted into the cylinder 272 formed in the projection 27 of the operator 8, and the opposite position is the inner wall 14 or the housing 13 of the housing 13. It may be fixed to the inner wall 14 of the cap fixed to the inner side.

On the inner circumferential surface of the cylinder 272 into which the piston 271 fixing one side of the torsion bar 270 is inserted, the torsion after the cylinder 272 rotates at a predetermined angle when the cover 2 rotates from the open position to the closed position. Torque torque is generated in the bar 270 to form the idle groove 273 to be the maximum when the cover 2 reaches the closed position.

Looking at the working relationship of the present invention configured as described above;

When the initial state is viewed in a state in which the cover 2 is folded in the main body 1, the torsion bar 270 of the operating means 150 in the housing 13 inserted into the rotating part 4 of the cover 2 is Cylinder formed on the projection 27 of the operator 8 and the inner wall 14 of the housing 13 or the inner wall 14 of the cap fixed to the housing 13 in a state of being twisted in the rotational direction of the rotational part 4. Since it is in the state fixed to the piston 271 inserted into 272, it will be in the state which has the largest torsional torque.

Although the force to open the housing 13 and the cover 2 is generated by the restoring force of the torsion bar 270, the operator 8 of the housing 13 and the inner wall 14 of the housing 13. ) And the compression spring 15-1 provided between the inner wall 14 of the cap fixed to the housing 13 are already compressed.

Therefore, the opening and closing slopes 12 of the clutch 10 and the engaging projection 9 of the operator 8 are coupled to each other so that the restoring force of the compression is greater than that of the torsional restoring force. (8) can maintain the current state because it is in the state coupled with the connecting shaft (7) connected to the button (5) that is rotatably coupled to the shaft connecting portion (3).

In this state, the coupling protrusion 9 of the operator 8 and the opening and closing slope 12 of the clutch 10 come into close contact with each other to compress the compression spring 15-1 to the closed position of the cover 2. Since the restoring force is greater than the restoring force due to the torsion of the torsion bar 270 pressed to the open position, the cover 2 can be kept closed.

That is, even if the compressive force is greater than the torsional force, the cover 2 is kept closed because the body 1 is closed. At this time, the force to close the cover 2 by the difference between the two forces exists so that the cover 2 ) Will remain closed.

In this state, when the cover 2 of the mobile phone 100 is to be opened, the operator 8 in the engaged state with the clutch 10 is pressed by pressing the button 5 coupled to the shaft connecting part 3. The compression spring 15-1 is spaced apart while being retracted, and at the same time, the torsion bar 270 rotates and the cover 2 coupled with the housing 13 rotates while generating a rotation force to return to its original state. To be open.

Looking at it in detail,

The button 5 is inserted into the button hole 6 formed in the shaft connecting portion 3 in a state in which rotation is impossible, but the linear reciprocating motion is freely in the axial direction of the connecting shaft 7.

Because of this, the actuator 2 and the piston 271 fixed to the torsion bar 270 coupled to the button 5 and the connecting shaft 7 do not rotate in the cylinder 272, but only linear reciprocating motion. The force is transmitted to the operator 8 through the connecting shaft 7 by pressing the button 5, and the operator 8 pushes the compression spring 15-1 inwardly of the housing 13. Given.

In this process, the torsion bar 270, which is coupled in a twisted state, is freely undone by the coupling protrusion 9 formed in the operator 8 and the clutch 10 and the opening and closing slopes 12 spaced apart from each other. The cover 2 is opened because it becomes possible.

In particular, when the operator 8 is sequentially released from the clutch 10 by pressing the button 5, a torsional state of the torsional force of the torsion bar 270 occurs, and the cover (e.g. 2) can be opened, since the open and closed inclined surface 12 is formed in the engaging groove 11 of the clutch 10, the smooth operation (opening) is possible.

To close the cover 2 after opening the cover 2 and making a call as described above, by rotating the cover 2 in the direction of the main body 1 by hand, the torsion bar having the minimum torsion torque ( 270) is twisted again to have maximum torsional torque.

As described above, the torsion bar 270 has a torsion torque and the compression spring 15-1, which is in a compressed state, is formed on the actuator 8 and the clutch 10 while the cover 2 is closed. (9) and the dog, the inclined slope 12 is combined to maintain the closed state by being locked.

When rotating the cover 2 in the closed position as described above, the torsion bar 270 is the projection 27 of the operator 8 and the inner wall 14 or housing 13 of the housing 13. It is fixed to the piston 271 inserted into the cylinder 272 formed on the inner wall 14 of the cap fixed to the idle, and idle by a predetermined angle by the idle groove 273 further formed in the cylinder 272 In the closed position of the cover 2 in which the torsion bar 270 has the torsional torque, the restoring force due to the compression of the compression spring 15-1 has the restoring force due to the torsion bar 270. It is relatively large compared to.

This is because when the cover 2 is rotated from the open position to the closed position, the torsion bar 270 does not immediately generate torsion torque by the idle groove 273 formed in the cylinder 272, and thus the opening degree of the idle groove 273 is maintained. When the torsion torque is generated in the torsion bar 270 after the cylinder 272 is idle, the compression force generated by the compression spring 15-1 while the cylinder 272 is idle is the torsion plane 29, This is because when the cover 2 is rotated from the open position to the closed position, it already holds a predetermined compressive force by the fixing means 153 or is a torsional compression inclined surface 53.

For this reason, when the restoring force due to compression is relatively large compared to the restoring force due to the torsion, the engaging protrusion 9 and the opening and closing slope 12 act on the closed state of the main body 1 and the cover 2. It is to be strengthened.

Of course, the torsion bar 270 has one side fixed to the operator 8 and the other side of the housing (8) when the operator 8 linearly reciprocates in the direction of the connecting shaft 7 when the cover 2 is opened and closed. Since it is fixed with the piston 271 inserted into the cylinder 272 formed in the inner wall 14 of the 13 or the inner wall 14 of the cap fixed to the housing 13, the connecting shaft ( 7) It would be natural to have a straight reciprocating motion in the direction.

As described above, the opening and closing of the cover 2 may be improved by being generated through the torsion bar 270 and the compression spring 15-1 provided with the torsion force and the compression force required when opening and closing the cover 2, respectively. It can be.

The present invention as described above is configured to maintain the relationship between the compression force and the torsional force in the opening and closing process without changing the relevant parts by independently configuring the torsional compression spring with the compression spring and the torsion bar so that the compression and torsional force is independently generated It can have the effect of contributing to the quality stability of the mobile phone having and the convenience of users.
