Fig. 11 is an exploded perspective view showing the terminal body 1 and the battery 3 for explaining the eighth embodiment according to the present invention, and has a screw hole 1e on one side (bottom surface) of the terminal body 1; Is provided, and the battery 3 is shown in the state in which the knob 21 which can be rotated freely is provided. And the knob 21 is protruded to the front, rear of the battery 3 is made so that the user can rotate by hand, and the screw 23 is integrally coupled to the rotation center. The screw 23 has a structure in which the screw 23 is fixedly coupled to the screw hole 1e by screwing.

In the above-described embodiment, the contents of the terminal body 1 and the battery 3 formed by the sliding movement have been described. However, the eighth embodiment has described a structure formed by screwing. Coupling by such a screw has the advantage that can be coupled to the battery 3 to the terminal body 1 without installing a separate fixing member has a simple structure.

In the eighth embodiment, the structure in which the knob 21 and the screw 23 are installed in the battery 3 is described. However, the structure is not limited thereto and may be provided in the terminal body 1.

FIG. 12 is an exploded perspective view showing the terminal body 1 and the battery 3 in a ninth embodiment according to the present invention. The fixing means 5 for fixing the battery to the terminal body 1 is shown. It is shown, the battery (3) is shown the locking step 41 is coupled to the fixing means.

Unlike the first embodiment described above, the fixing means 5 is housed inside the battery body 1 (not passing through the lower end of the body), and the battery 3 is positioned by the compression coil spring 9. It has a locking projection 43 in close contact with the direction to be.

And, on the battery 3 side is provided with a locking jaw 41 that can limit the movement of the battery 3 by the locking projection 43 to maintain the state in which the battery 3 is coupled to the terminal body (1) have.

When the engaging jaw 41 is coupled to the battery 3 to the terminal body 1, the terminal body 1 and the battery 3 is provided in a form inclined in the coupling direction so that the sliding movement can be smoothly.

Of course, the terminal body 1 has a dovetail groove 1a, and the battery 3 is provided with a dovetail protrusion 1a corresponding to the dovetail groove 1a so as to correspond to the battery 3. Can be combined.

This ninth embodiment has the advantage that the fixing means 5 is accommodated in the inside of the terminal body 1 to maintain the coupled state of the battery 3 while maintaining a beautiful appearance. In addition, since the locking jaw 41 has an inclined surface in the direction in which the battery 3 is coupled to the terminal main body 1, the coupling between the terminal main body 1 and the battery 3 is not moved to the locking projection 43. The binding can be made naturally without limitation. When detaching, the fixing means can be lifted up and detached.

In addition, the ninth embodiment describes a structure in which the fixing means 5 is provided in the terminal body 1 and the locking jaw 41 is inclined in the battery 3, but is fixed to the battery 3. The means 5 may be provided, and the terminal body 1 may have a structure in which the locking jaw 41 is inclined.

FIG. 13 is a sectional view conceptually showing FIG. 12 (a ninth embodiment) as a tenth embodiment. In FIG. 13 a fastening means 5 is shown for maintaining the engaged state of the battery 3. In FIG. 13, as described above, a structure in which the end of the dove tail groove is blocked may serve as a damper for stopping sliding.

In FIG. 13, the protruding portion h of the locking protrusion 43 does not protrude outside the bottom of the terminal body 1. That is, a groove (a portion in which the locking protrusion 43 is positioned) in which the locking protrusion 43 is accommodated is provided in the terminal body 1 so that the protruding portion h of the locking protrusion 43 does not protrude outward. will be. In FIG. 13, when the battery is simply pushed, the battery is mounted while the compression spring is naturally compressed by the locking jaw 42 of the inclined shape, and when the battery is detached, the locking protrusion 43 having the fluidity by the spring is vertically moved. The battery can be removed by sliding it open. The fixing part in FIG. 13 has a fluidity up and down by a spring, and does not have fluidity in left and right directions.

In FIG. 13, since the terminal side does not have the inclined locking jaw 42 protruding to the outside, it may not cause inconvenience in use even when the terminal is not mounted. In addition, the terminal side may have a fixing means having a compression coil spring. On the contrary, when the fixing means with the compression coil spring is placed on the battery side, since cellular batteries are usually provided with two batteries, it is necessary to provide the fixing means with the springs on the two batteries, which may increase the production cost. Can be. In this way, in Fig. 13 it is possible to place the fixing means with a spring on the terminal side, while not being inconvenient to use even when the battery is not installed, and to place the fixing means with the spring only on the terminal side so as not to increase the production cost, It is possible by placing the fixing means at the sliding start portion as shown in FIG. In the case of using the dovetail groove and the dovetail protrusion in mounting the battery on the rear side, the fixing means is provided at the sliding end, and when the battery is not installed, the locking jaw or the locking protrusion of the terminal protrudes to the outside. Therefore, it is one of the "important matters" of the present invention to put the fixing means on the terminal side in the vertical direction of the sliding direction, as shown in Figure 13, so that the terminal does not have a protrusion by sliding at the beginning. The same applies to the case where the battery is mounted on the back side.

FIG. 14 is an exploded perspective view illustrating an exploded view of the terminal body 1 and the battery 3 in the eleventh embodiment of the present invention, in which the battery 3 is coupled to the terminal body 1; A fastening means for holding is shown.

The fixing means has only a fixing member 43 which is arranged to slide the terminal body 1 repeatedly by a predetermined distance, and the catching member 43 can be inserted into the battery 3 corresponding thereto. The groove 45 is provided.

In addition, the terminal body 1 and the battery 3 are coupled to each other by the dove tail groove portion 1a and the dove tail protrusion 3a.

In addition, in order to prevent the flow of the battery 3 in a state in which the terminal body 1 and the battery 3 are coupled to each other, the groove 1f and the protrusion 3f having their own elastic force may be installed. . The groove 1f and the protrusion 3f may be used as a means for maintaining the combined state of the battery 3 even when there is no separate fixing means. In addition to this, the contacts 1g and 3g for power supply may have a similar effect by forming a hole and a ball, that is, a groove 1g and a streamlined protrusion 3g coupled to the groove. have. Since the streamlined protrusion for power supply is usually manufactured in a form having an elastic force, it may have a structure having elastic force itself or having an elastic member therein, similarly to the flow preventing protrusion 3f. The terminal having a hole-shaped groove may not cause inconvenience even when the battery is not installed. The same is true in other embodiments.

Fig. 15 is a perspective view of a portable mobile terminal showing a twelfth embodiment of the present invention, showing a state in which a plurality of batteries 3 can be coupled to the side of the terminal body 1. The twelfth embodiment is similar in effect to the eleventh embodiment, except that two small batteries or a small and medium battery can be combined to use a medium or large battery. have. Of course, in the twelfth embodiment, a structure in which two batteries 3 are coupled to a side surface of one terminal body 1 is illustrated and described, but is not limited thereto, and one or more batteries may be mounted on the terminal body 1. Can be combined on the side of the.

Fig. 16 is a perspective view of a portable terminal showing a thirteenth embodiment of the present invention, showing a state in which one battery can be mounted on one side and the bottom of the terminal main body 1. In this case, the coupling means can be suitably used in combination with the above-described embodiments. In the thirteenth embodiment, the portion coupled to the side portion of the terminal body 1 shows a means for engaging using the dovetail groove portion 3a, and the bottom side shows a structure consisting of screwing. Of course, you may change and use a coupling means suitably according to a position. Therefore, it is possible to apply except for the screw coupling structure in Figure 16, it is possible to apply to the "c" type battery without a screw coupling structure or including a screw coupling structure.

17 is a perspective view of a portable terminal showing a fourteenth embodiment of the present invention, showing another form of the eleventh embodiment described in FIG. That is, in the eleventh embodiment, the case where the fixing means is installed in the terminal main body 1 is described as an example. In the fourteenth embodiment, an example in which the fixing means is installed in the battery 3 is described.

However, the installation of the fixing means on the battery 3 side has a disadvantage in that a number of parts for the fixing means are usually required because the mobile terminal normally provides two batteries.

18 is a cross-sectional view of a portable terminal showing a fifteenth embodiment of the present invention, wherein a battery of another small capacity is provided on the back of the terminal body 1 with the battery 3 mounted on the side (bottom) of the terminal. (3) is shown combined. This has the advantage of utilizing the design of the existing terminal body to the maximum, and only a small capacity battery 3 is combined with the back of the terminal body 3 has the advantage that the effect of installing a medium or large capacity battery can be seen. . In FIG. 18, in the bottom battery mounting, one row of dove tail grooves and protrusions are used, but the dove tail grooves are provided on the terminal side, and the dove tail protrusions are illustrated on the battery side. However, the terminal side may have the dovetail protrusion and the battery side may have the groove portion. In particular, if the battery is mounted on the back as shown in Figure 25 it is more necessary. Thus far, since the battery side has the dovetail protrusion part and the groove part is the terminal side in mounting the battery on the back side, the protrusions at both ends constituting the dove tail groove part have no inconvenience. In the case of FIG. 25, even when the battery is not installed, the entire protrusion may not be provided on the entire rear surface of the terminal. This is one of the "important properties" in the present invention that allows for the optional mounting of a battery. Alternatively, in installing the rear battery, without having a single row of dove tail grooves and protrusions as shown in FIG. 25, two or more dovetail grooves and protrusions are formed as shown in FIG. 26, and the terminal side has a dove tail groove. You may

In the case of having a single dove tail groove portion and a protruding portion, the battery side may have a dove tail groove portion so as not to cause inconvenience even when the battery is not mounted. As shown in Fig. 27, when the rear battery is mounted, the battery side has a groove portion, and the terminal side has a protrusion portion, so that it may not cause inconvenience even when the battery is not installed. In Fig. 27, the opposite side of the fixing part (lower part in the drawing) can be aligned first, and the upper part can be pushed in the direction of the arrow to naturally mount the battery. To remove it, press the lock button down. The same can be applied to the case where the battery is mounted on the side. In the conventional detachable method, the terminal side has a groove portion and the battery side has a protrusion, which causes inconveniences when the battery is not installed.

In particular, as shown in FIG. 25, the structure of the battery 3 coupled to the rear surface of the terminal body 3 is provided with a dovetail groove in the battery 3, and the terminal body 1 has a dovetail. It may have a structure provided with a protrusion. The structure of the terminal body 1 and the battery 3 has a structure in which the battery 3 surrounds the terminal, and the rear surface of the terminal body 1 has a relatively flat surface. Even if (3) is removed, inconvenience in using the terminal body 1 can be minimized.

FIG. 26 is a diagram showing another embodiment corresponding to the fifteenth embodiment, in which a plurality of dovetail grooves 1a are provided on both side sides of the terminal body 1, and a middle portion thereof is a dovetail. The state provided with the protrusion part is shown. The battery 3 corresponding to the terminal body 1 has a structure having dove tail protrusions at both sides and a dove tail groove at the center thereof. This embodiment also minimizes the grooves or protrusions that may be formed on the rear surface of the terminal body 1 to remove the battery 3 coupled to the rear surface to maintain the beauty of the appearance and reduce the inconvenience in use.

Fig. 19 is a perspective view of a portable terminal showing a sixteenth embodiment of the present invention, in which the battery 3 is coupled to the side (bottom surface in the drawing) of the first body including the input device as the terminal body 1; The terminal of the structure which can selectively insert or withdraw the 2nd main body provided with the display apparatus 51 which can be accommodated in the 1st main body 1 is shown. Such a terminal can provide a structure capable of adding a second body provided with a display device 51 as a peripheral device to a relatively thinner terminal body 1 by moving a battery disposed in the terminal body 1 to another side. have. Therefore, the user can use a peripheral device in which a plurality of screens, a large screen larger than a conventional screen, or a keyboard are installed.

20 is a perspective view of a portable terminal showing a seventeenth embodiment. In the seventeenth embodiment, the operational effects of the sixteenth embodiment described in FIG. 19 are similar. However, the second body with the liquid crystal display device 51 is different from the sixteenth embodiment in that it has a structure in which it is hinged to the first body including the input device which is the terminal body 1. That is, in the structure of the seventeenth embodiment, the second main body provided with the display device 51 is hingedly coupled to an axis disposed perpendicular to the plane of the input device on the first body provided with the input device. This shows that the wider screen can be used by combining the second body provided with the liquid crystal display device 51 with the hinge point on the first body having the input device.

21 is a perspective view of a portable terminal showing an eighteenth embodiment. The eighteenth embodiment shows a structure in which the keyboard 53 can be hinged to the terminal body 1 having a foldable shape. The eighteenth embodiment can also be viewed as another form of the above-described embodiment, and the effect is the same as the above-described embodiment.

Fig. 22 is a perspective view of a portable terminal showing the nineteenth embodiment. The nineteenth embodiment shows a liquid crystal display 51 which is hinged to the lid of the terminal body 1, which is made of a clamshell, and folded to the lid 71 side.

23 is a perspective view of a portable terminal showing a twentieth embodiment. The twentieth embodiment has a liquid crystal display 51 which is hinged to the cover of the terminal body 91 having a folding shape and is folded toward the cover 71, and the keyboard 53 is hinged to the terminal body 1. The structure which can be folded to the terminal body 1 side is shown. In the above-described nineteenth and twenty embodiments, an input / output device (for example, a liquid crystal or a keyboard) is selectively installed and installed in the terminal body 1 or the folding terminal cover 71, respectively, so that it can be carried conveniently and conveniently. It is to provide a terminal. Extending the terminal in the form of FIG. 23 has the advantage of providing an easy structure in which a right-handed user grips the terminal with his left hand and manipulates the terminal with his right hand. 22 and 23, in order to utilize both sides of the liquid crystal as one screen, it is necessary to have a structure in which the hinge portion to be folded is not broken. This can be used as one of means to overcome the small liquid crystal size in the portable terminal. 21, 22, or 23, it is obvious that the terminal can be expanded by applying the method of FIG. 19 or 20 in extending the terminal.

FIG. 24 shows a state in which the terminal body 1 and the battery 3 showing the twenty-first embodiment of the present invention can be combined. The terminal body 1 has a dovetail groove 1a on one side (on the bottom). The dovetail groove portion 1a has a groove 1g asymmetrically formed at one side thereof in the width direction of the dovetail groove portion 1a. That is, the depths a and b of the grooves are different from each other, and the angles forming the grooves are also configured differently.

The battery 3 corresponding to the terminal body 1 has a dovetail protrusion 3a, and has a structure that is fitted to the dovetail groove 1a described above. As for the dovetail protrusion 3a, the protrusion 3g which is asymmetrical to one side is formed in the width direction of the dovetail protrusion 3a. That is, the depths a and b of the protrusions 3g are different from each other, and the angles forming the protrusions are also different. And the protrusion part 3g has the structure which fits in the groove 1g mentioned above. This structure can combine the terminal body 1 and the battery 3 in a simple structure without a separate fixing means. Of course, this interference fit structure and a separate fixing means can be applied in parallel. 12 and 13 are not provided with an elastic member, and as shown in FIG. 24, the locking jaw is asymmetrically streamlined so that the interference fit structure can be applied using the flexibility of the plastic material.

FIG. 27 is a view showing a twenty-second embodiment according to the present invention, which shows a state in which a locking groove into which the battery 3 can be fitted is provided on the bottom and rear sides of the terminal body 1. have. And the upper end of the back of the terminal body 1 is provided with a locking member 71 to which the battery 3 can be fitted. The locking member 71 has a locking groove for holding the battery 3 in a fixed state and is elastically supported by an elastic member 73 made of a compression coil spring or the like. In addition, the battery 3 is preferably a shape made to be coupled in a form surrounding the terminal body (1). The terminal body 1 is provided with a locking groove having an inclined surface at the bottom or top of the back, front, top, bottom, left and right sides, and another hook at the top or bottom of the back, front, top, bottom, left and right sides. It is possible to provide a groove.
