When the portable terminal is provided with a flash 3 for taking a camera or a mirror 4 for taking a self-camera, an opening corresponding to the flash 3 and the mirror 4 to be exposed to the outside ( 11) may be further formed.

Even if the guide 10, the fixed plate 40, and the protective cover 50, which will be described later, are combined with the case 10, the case 10 is a sliding section of the protective cover 50 so that the degree of protruding from the case 10 is minimal. It is preferable to have a sliding surface 12 while grooves are formed at a thin depth, and the opening 11 is formed at one side of the sliding surface 12.

The four side walls of the sliding surface 12 serve as a guideline when the protective cover 50 is slid, and also the insertion of the protruding ball 33 into the recess 42 to be described later in the opening / closing position of the opening 11. In addition to the role of fixing the position of the protective cover 50.

The guider 20 is fixedly coupled to the position of the sliding surface 12 that does not interfere with the opening 11, since the degree of protrusion on the case 10 due to the thickness of the guider 20 should be considered. It is preferable that the groove having a thin depth is formed on the sliding surface 12 to which the guider 20 is coupled, and the guider 20 is seated and coupled thereto.

On both sides of the guider 20, guide walls 21 having a longitudinal direction toward the opening 11 are formed side by side, and guide grooves 22 are formed in the longitudinal direction on the inner surface of the guide wall 21.

Guide piece 41 of the fixed plate 40 to be described later is coupled to the guide groove 22 to be slidable, the material of the guider 20 is preferably made of a polymer-based fixed plate 40 made of a metal material If necessary, the required play can be minimized.

A seating groove 23 is formed in the upper side surface of the guider 20 between the guide walls 21, and the elastic protrusion part 30 to be described later is seated in the seating groove 23.

The seating groove may be integrally formed in the guider 20, but as shown in FIG. 3, a separate seating member 24 in which the seating groove 23 is formed may be coupled to the guider 20.

The elastic protrusion part 30 provided in the seating groove 23 has a coil 31 and a coil provided in the housing 31 and the housing 31 which are coupled to the seating groove 23 while the upper side is open. Located on the upper side of the spring (32) is made of a projection ball 33 is coupled to the upper side of the housing 31 so as to project the upper end to the housing (31).

The protruding ball 33 may be elastically supported by the coil spring 32 and elastically flows upward and downward in the housing 31. In addition, the protrusion ball 33 is preferably formed in a spherical shape so that the bottom surface of the fixed plate 40 to be described later is in contact with the protrusion ball 33 to roll while rolling the protrusion ball 33.

The housing 31 is seated and coupled to the seating groove 23, wherein the housing 31 is coupled to the seating groove 23 to facilitate the coupling of the housing 31 to the seating recess 23 and not to flow, but is not shown. A thread is formed and correspondingly, a screw groove is formed on the inner circumferential surface of the seating groove 23 so that the screw thread may be coupled to each other.

The guider 20 preferably has a minimum width in consideration of the diameter of the opening 11 so as to minimize the area occupied on the case 10. The fixing plate 40 slidably coupled to the guider 20 may include: It has a flat shape and has a width approximately corresponding to the width of the guider 20.

On both sides of the fixing plate 40, guide pieces 41 which are inserted into the guide grooves 22 described above and slidable are bent. By the sliding structure, even if the fixing plate 40 is made of a metal material, the metal friction sound is minimized.

The fixing plate 40 is formed with a groove 42 through which the upper end of the above-described protrusion ball 33 can be elastically inserted or detached, and the groove 42 has a fixed plate 40 opening the opening 11. In the position of the state and the opening portion 11 in the closed position when the projection ball 33 is inserted so that the fixing plate 40 is fixed to the position of the projection ball 33 in the above-described respective positions Correspondingly formed respectively.

According to the present embodiment, the fixed plate 40 is in contact with the spherical projection ball 33 in the sliding process, while sliding the projection, the spherical projection is rolled, the top of the groove 42 in the position of the groove 42 ) Will have a structure that is elastically inserted or removed.

This structure of the present embodiment has a structure in which the metal friction sound is minimized even though the fixed plate 40 is made of a metal material together with the sliding structure described above.

The seating groove 23 may be formed at one place on the guider 20 so that one elastic protrusion 30 may be seated and coupled thereto, but the opening 11 may be easily and smoothly slid in the range of the fixing plate 40. It is preferable that the two mounting grooves 23 are formed on the guider 20 so that the position fixing can be more secured at the opening / closing position thereof.

In this case, the seating groove 23 may be integrally formed in the guider 20 as described above, but a separate seating member 24 in which two seating grooves 23 are formed may be coupled to the guider 20. Do.

The fixing plate 40 corresponds to the protrusion balls 33 of the elastic protrusions 30 provided in the respective seating recesses 23 at respective positions at which the fixing plate 40 opens and closes the opening 11. Each pair of grooves 42, that is, four grooves 42 are formed in all.

At this time, the two mounting grooves 23 are formed diagonally with respect to the sliding direction of the fixed plate 40 on the guider 20, and it is preferable that the elastic protrusions 30 are provided here, respectively, Paired groove 42 is also preferably formed in the fixed plate 40 diagonally.

When the groove 42 is divided into each pair, each of the grooves 42 closer to the opening 11 in each pair, the projection ball 33 is located closer to the opening 11 of the projection ball 33 This is to be inserted in each opening and closing position, and to allow the remaining projection ball 33 is inserted into each remaining groove 42, respectively.

If the pair of grooves 42 are continuously formed in the fixing plate 40 on the line corresponding to the sliding direction, and the seating groove 23 and the elastic protrusion part 30 also correspond to the guider 20 on the same line. When positioned on the projection plate 33 located closer to the opening 11 in the sliding process of the fixing plate 40 in turn in a pair of grooves 42 in a position closer to the opening (11) Can be inserted.

This causes a problem that the fixing plate 40 can be fixed in position at an unnecessary point in the middle, not the opening and closing position, as shown in the present embodiment, the groove 42, the seating groove 23 and the elastic protrusion 30 are diagonal. This problem does not occur when the forge is formed and connected.

In addition, this also has the purpose of reducing the area of the guider 20, if the area occupied by the guide surface 20 sliding surface 12 is wider the coupling surface of the guider 20 formed in the sliding surface 12 that much In this case, there is a problem of encroaching the installation space of the other internal parts of the portable terminal provided in the bottom of the case 10.

However, according to the present embodiment, the elastic protrusions are diagonally diagonally while utilizing the width of the guider 20 as compared with the case where the groove 42, the seating groove 23, and the elastic protrusions 30 are positioned on the line corresponding to the sliding direction. The position of the fixing plate 40 is further improved than the case where the distance between the protruding balls 33 (the position of the elastic protrusions 30 in the sliding section is positioned too close to each other) is positioned so close to the position of 30. It is possible to reduce the area occupied by the guider 20 on the case 10 while maintaining the appropriate distance at this time).

As described above, the guider 20 of the present embodiment may have a proper width considering the diameter of the opening 11 and may not be long, so that the groove area of the sliding surface 12 on which the guider 20 is seated is provided. Will not be that wide.

The remaining sliding surface 12 except for this area can be formed by a very thin groove in the case 10, even if the case 10 is provided with the above-described configurations for the protection of the camera lens 2. The degree of protruding above the case 10 and below the case 10 is not large.

The upper side of the fixed plate 40 is coupled to a protective cover 50 of a thin thickness so that the guider 20 and the fixed plate 40 is not exposed to the outside, the protective cover 50 is sliding of the fixed plate 40 The opening 11 is opened and closed while sliding together.

The protective cover 50 is slid by the pressurization of the user in the opening and closing direction of the opening portion 11, in which case the protective cover 50 may slide in contact with the sliding surface 12, and thus the sliding surface 12 Scratches and noise may occur due to friction with the protective cover 50.

These scratches are exposed to the outside according to the sliding of the protective cover 50 to damage the appearance of the portable terminal.

In order to prevent this, the protective cover 50 may be further provided with slip members 51 on the bottom surfaces of both ends, and the slip members 51 are preferably wear-resistant, such as POM (Poly Oxy Methylene, polyoxymethylene). By being made of a plastic material having excellent fatigue resistance and toughness, noise can be reduced while preventing scratches due to friction between the slip member 51 and the sliding surface 12.

The slip member 51 is made of a POM material which is coupled to the fixing piece 52 fixed to the bottom surface of the protective cover 50 to be easily fixed to the protective cover 50 and the fixing piece 52 by a coupling method such as interference fit. The slip piece 53 may also be included.

Combination of the fixing plate 40 and the protective cover 50 may be a pin fixing, screw fixing, etc., but the thickness of the protective cover 50 is formed so thin that the degree of protruding on the case 10 is small In consideration of this point, it is preferable that the fitting groove 54 is provided in the aforementioned slip piece 53 provided at the bottom of one end of the protective cover 50, unlike the fixing method described above. Correspondingly, the fitting piece 43 may be formed to protrude to one end so that the fitting pieces 43 are coupled to each other. In addition, the convenience of assembly may be further improved by the coupling method.

The slide protection module (1) for protecting a camera of a portable terminal according to the present invention has a magnetic sensor (not shown) capable of controlling the operation of the camera depending on whether the opening part 11 is opened or closed by sliding the protective cover 50. It may be further included.

In this case, the magnet part 55 is fixed to the bottom of the protective cover 50 so as to be moved together with the sliding of the protective cover 50, and a magnetic sensor capable of detecting the positional movement of the magnet part 55 is portable. It is mounted at a predetermined position of the terminal.

The magnet part 55 is fixed to the bottom of the protective cover 50 by a fixed tape 56 or the like, and at this time, the magnet part 55 is provided at the other end of the fixing plate 40 located at the bottom of the protective cover 50. Slot 44 that can be fitted is formed in the longitudinal direction, that is, the sliding direction of the fixed plate 40 so that one side is opened.

Since the magnet part 55 is fixed to the protective cover to be exposed to the bottom of the fixed plate 40 through the slot 44, the magnetic sensor does not interfere with the position of the magnet part 55 without being disturbed by the fixed plate 40. It can be detected.

In addition, since the magnet part 55 is moved together with the protective cover 50 while being fitted in accordance with the slot 44, the fixing plate 40 coupled to the bottom surface of the protective cover 50 is the protective cover 50. While being supported by the magnet unit 55 fixed to the sliding left and right flow without being even more so that noise such as friction noise is not generated.

The magnetic sensor mounted on the portable terminal detects the presence or absence of a magnetic material when the magnet part 55 moves to the sensing position or moves away from the sensing position to determine whether the opening part is opened or closed by the protective cover.

Thereafter, the detection signal is transmitted to a control unit (not shown) mounted on the portable terminal, and the control unit controls the on / off of the camera according to the received detection signal.

Although the magnetic sensor may detect the presence or absence of the magnetic material, it is also possible to transmit the above detection signal by detecting a change in the magnetic field direction (polarity change), and various other magnetic sensors may be provided.

Since the present invention can be variously modified and implemented by those skilled in the art without departing from the scope of the claims claimed in the claims, the technical protection scope of the present invention is limited to the specific preferred embodiments described above. It is not limited.
