Description

Slide Hinge {Slide Hinge}

Portable devices such as mobile communication terminals and cameras have various types of opening and closing methods in consideration of functionality and design. When the front part of the device is opened and closed by sliding from the main body part, tensile compressive force is generally generated in a straight or curved direction. It consists of the arrangement of the coil spring 2 to be made and the rod structures 1 and 4 which support this force and transmit the actuation force to other mechanisms (refer FIG. 1).

In fact, even if four coil springs 2 used to generate a driving force for sliding are taken as shown in Fig. 1, the outer diameter is 1.2 mm or more, and includes the accompanying mechanisms 3 and 3a. Since the thickness occupies more than 1.5mm, it is impossible to configure the module within 1.2mm, the minimum mounting space for the slim sliding terminal.

In addition, at least two to four springs, at least two to four rods, and welding or assembly points for at least four to six parts are required.Therefore, there are limitations in product price reduction and thickness reduction. Due to the structure, there is a problem in that the driving force decrease according to the increase in the number of opening and closing is relatively large.

In addition, looking at the recent devices, the active transmission and reception of images to the mobile phone, a rapidly increasing number of devices adopting a wide screen, the device itself is about 2cm long, which is suitable for long strokes, slides that can solve the above problems Hinge is required.

The present invention aims to provide a slide hinge suitable for long strokes, overcoming the problems and limitations of the conventional slide hinge through the selection of the spring and the improvement of the connection structure and the rod structure.

The present invention, in order to solve the above problems, is wound around the one end in the same plane in the inward direction, when reaching the center is wound in an outward direction by different layers to form a first spiral portion, the straight portion is separated from the first spiral portion And forming a second spiral portion formed in a reverse order to the process of forming the first spiral portion at a position diagonally symmetrical with the first spiral portion with respect to the straight portion, and the outer coupling portions having both ends are provided with a first spiral portion and a first spiral portion. A spring which is opened from two helixes and configured to face each other in an opposite direction; A linear coupling part for receiving and fixing the outer coupling part, a device coupling part formed at a free end side of the linear coupling part, a mobile coupling part extending in an inner direction in which the outer coupling part is formed at the other end of the linear coupling part, and the movable coupling part A pair of rods provided with at least one guide pin on the upper portion of which the width of the upper portion is relatively large; And an arc wound around the first spiral portion and the second spiral portion between the first spiral portion and the second spiral portion in a 'S' shape, and the guide pin moves on the circular arc at both ends thereof. A connecting slide having a guide rail capable of coupling the pair of rods to each other; And a guide pin of the pair of rods is fitted to the guide rail of the connecting slide part to simultaneously move on an arc along the guide rail, while the spring is configured to elastically move.

According to the present invention, only four parts are required and can be produced in a single process through insert injection, thereby reducing costs and dramatically increasing mass productivity compared to the conventional technology of providing a long stroke. Since it surrounds the spring (outer coupling part) of this spring, it is advantageous to ensure flatness and improve assembly property, and can improve the completeness of a product.

In addition, it is possible to slim design with the thickness that is twice the diameter of the spring as a whole, and to apply more preload to be mounted on the product in a limited space, so that it is easy to implement stable driving force at both ends, thereby securing the FPCB area or the device. Can greatly contribute to the miniaturization of cemented carbide.

2 is a slide hinge according to the present invention, which shows the initial state of the assembly is completed, a pair of rods 20 and a pair of rods 20 for supporting the spring 10 and both ends of the spring coupled to the device It includes a connection slide unit 30 for coupling.

The spring 10 is configured such that the outer coupling portion 101, which is a coupling end, faces in the opposite direction from the inside, and looks at a specific shape, it winds in the inward direction on the same plane about one end and reaches the center. By different from now it has a first spiral portion (102) wound in the outward direction on the same plane in the center.

Subsequent to the first spiral portion 102, a straight portion 103 which is formed apart from the first spiral portion is formed to have a predetermined length.

After the straight portion 103, a second spiral portion 104 formed in a reverse order to the process of forming the first spiral portion at a position diagonally symmetrical with the first spiral portion with respect to the straight portion.

Since the second spiral portion is formed in the reverse order of the first spiral portion, the second spiral portion may have the same thickness on the same plane as the first spiral portion.

The outer coupling portion 101 is finished to face in opposite directions from the inside of the spring in a shape that is spaced apart from the spiral portions 102 and 104 so as to elastically act on the front and body portions of the device.

The spring 10 is coupled to the device as a result of the outer coupling portion 101 coupled to the pair of rods 20 as a coupling end.

The pair of rods 20 includes a linear coupling part 201 for receiving and fixing the outer coupling part 101, a device coupling part 202 formed at a free end side of the linear coupling part 201, and the straight line. At the other end of the coupling portion, the movable coupling portion 203 extending in the inner direction formed by the outer coupling portion 101 and a guide pin having a relatively large width on the movable coupling portion 203 as a locking jaw ( 204 is provided.

The guide pins 204 may be formed in two or more in order to satisfy the driving force required according to the scale of the device.

In order to couple between the pair of rods, an arc circumscribing the first spiral portion and the second spiral portion between the first spiral portion 102 and the second spiral portion 104 is symmetric in a 'S' shape. On the circular arc of both ends, a connecting slide portion 30 having a guide rail 301 through which the guide pin can move on the circular arc is provided.

The guide pin 204 is coupled to the guide rail 301 of the connecting slide unit 30 so that the pair of rods move along the guide rail on an arc at the same time so that the spring moves elastically.

The guide rail 301 should be formed over the entire range in which the guide pin 204 is moved according to the expansion and contraction of the spring, the width of the guide rail 301 is larger than the lower width of the guide pin but the width of the upper portion It should be smaller than the guide pin so that it can stably move on the arc of the guide rail in the spanned state.

In addition, when there are a plurality of guide pins 204, a plurality of guide rails 301 must be provided in parallel in accordance with the movement path of the guide pins.

An intermediate point of the connection slide portion 30 is provided with a recess 302 that can accommodate the straight portion 103 of the spring, it is preferable to configure so that the thickness is not increased.

As a result, the pair of rods 20 may be coupled to each other and interlocked with each other, and the pair of rods move simultaneously in the inner angle range of the spring while moving on an arc, and the elastic movement by the expansion and contraction of the spring fixed thereto is fixed. This becomes possible.

Although the thickness of the slide hinge according to the present invention can be variously implemented, it is preferable to form the range of twice to four times the diameter of the wire as a whole. In order to form the most slim, the guide pin 204, a pair of If the total thickness (height) of the rod 20 and the connecting slide portion 30 is formed in the range of twice the spring diameter or the wire diameter, the entire thickness can be formed in the range of twice the spring diameter.

Figure 3 illustrates the assembly process of the slide hinge according to the present invention in order.

As shown in (a), the spring 6 is first provided, and then, as shown in (b), the pair of rods 20 and the spring 10 are coupled.

In the coupling method of the rod and the spring, it is preferable that the spring 10 and the rod 20 are integrally formed by insert injection after the spring is seated in the mold of the rod. No separate parts are required for post bonding and a rigidly combined slide hinge can be completed by a single injection process.

However, after the rod is manufactured separately through a molding process such as injection or die casting, the rod may be coupled to both outer coupling portions 101 of the spring.

In the state of (b) completed as described above, when the guide pins 204 of the pair of rods 20 are finally fitted onto the guide rails 301 of the connecting slide part 30 as shown in (c), The slide hinge is completed in the initial state.

Since the guide pin 204 is larger in width than the lower part, the guide pin 204 cannot be inserted into the guide rail 301. The upper part of the guide pin in consideration of the operating angle range of the spring unit at any point of the guide rail is The insertion hole 303 can be easily formed.

As shown in the drawing, two guide holes 303 are formed in each guide rail, and when mounted in a mobile phone, the coupling is facilitated, and the straight portion 103 of the spring is supported by the recess 302. There is no risk of falling back into the insertion hole.

Figure 4 is an operation example of the slide hinge according to the present invention, (a) the initial state, (b) during operation (dead center) and (c) shows the sliding movement complete state.

When (a) <-> (b) <-> (c) is repeated and slides, it can be seen that the space occupied by the entire stroke and elastic range can be minimized while the long stroke is sufficiently implemented.
