A front housing 10 having cut portions 16 formed thereon, and a rear housing fixedly coupled to the rear surface of the front housing 10 by a screw 11 to cover the rear opening of the front housing 10. (20) and a belt clip (30) detachably installed in the elongate receiving groove (22) formed on the rear surface of the rear housing (20) to change the mounting positions of the front and rear housings (20), and the rear It is disposed in the elongated receiving groove 22 formed on the back of the housing 20 Locking member 40 to prevent separation of the belt clip 30 and the left and right side walls of the receiving groove 14 formed in the front housing 10 is rotatably installed on the left and right side walls of the mobile phone 12 A pair of clampers 50 are inserted into the grooves formed therein to restrict the detachment of the mobile phone 12 during charging, and are installed at an upper portion between the front housing 10 and the rear housing 20 so that the clampers ( A shaft 71a and a coil spring 71b are disposed at a lower portion of the release button 60 for regulating the protruding (entering out) of the protrusion 50c of the 50 and the receiving groove 14 formed in the front housing 10. It is disposed in the space formed by the interface connector 70 and the front housing 10 and the rear housing 20 which are provided in the block 71 so as to be able to pivot through it, and are traveled by the control of the charging control circuit 80. The secondary battery 210 is charged with the DC voltage converted by the adapter 200. It is made.

The belt clip 30 has a pair of protrusions 31a and 31a formed at an upper portion thereof, and grooves 31c into which the protrusions 42 of the lock member 40 are inserted are formed at a lower portion thereof, respectively. A pair of coupling members 31 inserted into the elongated receiving groove 22 formed on the rear surface of the 20 and fixed by the lock member 40 and a circular protrusion 31d of the coupling member 31. The circular protrusions 32a and 32b respectively inserted into the grooves 31b and 31b are integrally formed, and at the same time, the locking member 32c and the coil spring 32d which bias the locking member 32c are disposed. Fixed to the rotary subunit 32 and the circular projection (31d) of the coupling member 31 by integral welding to rotatably receive the rotary member 32 in a clockwise or counterclockwise direction, respectively. A member 33, a movable member 34 provided on the fixing member 33 so as to be pivotable about a hinge pin 33a, and the Wherein the distal end of the ET material 34 (the lower in Fig. 6) consists of a lower coil spring 35 for biasing the plate to each key on the fixed member (33).

The lock member 40 is formed integrally with the slider 41 which is urged upward by a spring (not shown) as shown in FIG. Projections 42 inserted into the grooves 31c formed below the coupling member 31 of the coupling member to prevent the belt clip 30 from being separated, and the elongated accommodation grooves 22 formed on the rear surface of the rear housing 20. And a projection plate 43 integrally formed on the slider 41 to slide the slider 41 downward so as to separate the belt clip 30 detachably attached to the belt clip 30.

As shown in FIG. 11, the clamper 50 protrudes the pair of projections 50c when the tension spring 51 installed on the shaft 51a and the release button 60 are released. When the lower actuating member 52 which is urged clockwise by the biasing force of the tension spring 51 and the release button 60 are pressed, the release to retreat the pair of protrusions 50c respectively. The upper operation lever 53 is provided in the hinge shaft 50a so as to contact the inclined surface 64 formed to be inclined inwardly at the lower part of the button 60 and turn counterclockwise.

The release button 60 is urged upward by the coil spring 62 to push the protrusion 50c of the clamper 50 toward the receiving groove 14 formed in the front housing 10.

In the drawing, reference numeral 202 denotes a cord for connecting the travel adapter 200 and the connector 208, 204 denotes a wire for electrically connecting the interface connector 70 and the charge control circuit 80, and 206 denotes the above. It is a charging wire for charging the DC power to the secondary battery 210 through a charge control circuit 80.

In addition, the LED1 shown in FIG. 12 emits orange color when the battery of the mobile phone 12 and the secondary battery 210 are simultaneously charged, and the DC power charged in the secondary battery 210 is emitted. When the battery of the mobile phone 12 is charged, the LED emits red light.

Next, the operation and effects of the portable charging device 1000 of the mobile phone according to the embodiment of the present invention configured as described above will be described.

First, to charge the battery of the mobile phone 12 and the secondary battery 210 in the portable charging device 1000 of the mobile phone according to an embodiment of the present invention, shown in Figures 9 and 10 As described above, while the mobile phone 12 is pushed into the receiving groove 14 formed in the front housing 10, a charging terminal (not shown) formed at the bottom of the mobile phone 12 is connected to the interface connector 70. Connect.

At this time, the projections 50c of the clampers 50 respectively provided on both side walls of the accommodation groove 14 formed in the front housing 10 are inserted into the grooves formed on both sides of the mobile phone 12, respectively. 12 does not depart from the portable charging device 1000 of the mobile phone of the present invention. In other words, when the projections 50c of the clampers 50 respectively installed on both side walls of the accommodation groove 14 formed in the front housing 10 are inserted into the grooves formed on both sides of the mobile phone 12, FIG. 11. As shown in the lower actuating lever 52 integrally installed in the lower portion of the clamper 50 is rotated counterclockwise about the hinge axis (50a) against the bias force of the tension spring (51) At the same time, the upper operating lever 53 also easily pushes the mobile phone 12 into the receiving groove 14 formed in the front housing 10 as it rotates counterclockwise around the hinge shaft 50a. I can put it.

When the mobile phone 12 is completely mounted in the receiving groove 14 formed in the front housing 10, the upper actuating lever 53 and the lower actuating lever 52 by the force of the tension spring 51. ) Rotates clockwise around the hinge shaft 50a, so that the projections 50c of the clamper 50 are inserted into grooves formed on both sides of the mobile phone 12, respectively, to allow the mobile phone 12 to be rotated. This is firmly fixed to the portable charging device 1000 of the mobile phone of the present invention.

As such, the connector 208 installed on one side of the cord 202 in a state in which the mobile phone 12 is infiltrated into the receiving groove 14 of the front housing 10 of the portable charging device 1000 of the mobile phone of the present invention. Is electrically connected to a charging connector (not shown) installed in the portable charging device 1000 of the mobile phone according to the present invention, and then the plug 200a of the travel adapter 200 installed on the other side of the cord 202. ) Is connected to a 110Vac or 220Vac outlet, and receives 110Vac or 220Vac from the travel adapter 200 and converts it into a DC voltage and supplies it to the charging control circuit 80.

Accordingly, the battery of the mobile phone 12 and the secondary battery 210 are simultaneously charged with a DC voltage by the control of the charging control circuit 80. At this time, the dual type light emitting diode LED1 is It emits orange color.

On the other hand, when the battery of the mobile phone 12 is first charged during the charging, the dual type light emitting diode LED1 emits light of red color only to indicate that the secondary battery 210 is being charged. When the charging of the battery 210 is completed first, the dual-type light emitting diode LED1 emits green light to indicate that the battery of the mobile phone 12 is being charged, and the battery of the mobile phone 12 and the When both of the secondary batteries 210 are charged, the dual type light emitting diode LED1 does not emit light, indicating that both the battery of the mobile phone 12 and the secondary battery 210 are charged.

When the battery of the mobile phone 12 and the secondary battery 210 is charged as described above, by pressing the release button 60 of the portable charging device 1000 of the mobile phone according to an embodiment of the present invention After immersing the protrusion 50c of the clamper 50 into the inside, the mobile phone 12 can be removed and carried while carrying a call.
