[0001] The present invention relates to a portable radio such as a mobile phone, and more particularly to a battery holding structure of a portable radio in a wireless communication system such as a fire radio.

Background Art

[0002] As a conventional battery fixing structure of a mobile phone, there is a structure composed of a fixing claw provided at an engaging portion between the lower end of the battery and the lower end of the device body, and a locking member having a movable structure provided at the upper end of the battery (see Patent Document 1).

[0003] As an example of a method for locking a battery 23 used in a conventional mobile phone to a rear case 22 of a device body 21, as shown in FIG. 13, a spring hinge 25 provided integrally with the battery 23 so as to be detached to the side opposite to the rear case with a battery fulcrum claw 24 formed at the lower end of the rear case 22 as a fulcrum fixes the battery 23 to the rear case 22 by the claw 26 thereof and a recess 27 into which the claw 26 provided in the rear case 22 fits.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the conventional method shown in FIG. 13, when removing the battery 23, the spring hinge 25 is moved in the direction A in the figure, and the battery 23 is moved in an arc direction around the fulcrum claw 24 at the lower end.

[0006] However, the above configuration of the device had the following problems. For example, in the configuration shown in Figure 13, it is necessary to provide a pivot claw 24 at the lower end of the rear case 22 and a recess shape corresponding to the pivot claw 24 at the lower end of the battery 23. Therefore, the height dimension of the device increases by the amount of space required for the engagement part (dimension L in Figure 13), which hinders the miniaturization of the device (reduction of the height dimension). In addition, in the configuration disclosed in Patent Document 1, the user removes the battery 23 by moving the locking member (hinge 25) on the back of the device, but the user is likely to unintentionally touch the hinge 25 on the back of the device, and in such cases, the hinge 25 may be misoperated and the battery 23 may fall out of the device body 21.

[0007] This invention has been made in view of the above points, and aims to provide a portable wireless device that can reduce battery detachment due to accidental operation. [Means for solving the problem]

[0008] The portable wireless device according to the present invention comprises a battery and a main body having a storage section for detachably storing the battery, wherein the battery has a plurality of first engaging portions provided on the upper part of the battery, and the storage section has a plurality of first engaged portions, each provided on the upper part of the storage section, which are elastic and engage with each of the plurality of first engaging portions and allow the engagement to be released. [Effects of the Invention]

[0009] According to the present invention, a portable radio can be obtained that reduces the height dimension of the device and enables miniaturization by providing a fixing claw on the upper end of the battery on the back of the device and a first engaged part, which is a movable locking part, on the device body (also simply called the body). Furthermore, by providing multiple movable locking parts on the back of the device, a portable radio can be obtained that reduces the risk of battery detachment due to accidental operation. Moreover, by arranging the movable locking part on the back of the device and the top of the battery adjacent to each other, a portable radio can be obtained that allows the user to remove the battery by pressing the movable locking part with their fingertip while simultaneously placing their finger on the top of the battery.

[0011] Hereinafter, a mobile radio device according to an embodiment of the present invention will be described in detail with reference to the drawings. In the embodiments, components having substantially the same functions and configurations are denoted by the same reference numerals, and redundant descriptions are omitted.

[0012] (First Embodiment) (Description of Configuration) The configurations of the mobile radio device according to the first embodiment are shown in FIGS. 1 to 5. For the sake of convenience of description, as shown in each figure, the directions of the respective axes of the orthogonal XYZ coordinate axes are defined as the XYZ directions, the front and back directions of the mobile radio device are defined as the Z direction, and the left and right (X direction) and up and down (Y direction) directions are described as viewed from the back of the mobile radio device. FIG. 1 is a schematic perspective view showing the overall appearance of the mobile radio device of this embodiment. FIG. 2 is a schematic perspective view showing the device main body 3 of the mobile radio device. FIG. 3 is a schematic perspective view showing the battery 1 of the mobile radio device. FIG. 4 is a schematic side view showing the appearance of the mobile radio device. FIG. 5 is a schematic rear view showing the appearance of the mobile radio device.

[0013] As shown in FIG. 1, the mobile radio device includes a battery 1 and a main body 3 having a storage portion KN for detachably storing the battery 1 at the lower rear portion. The storage portion KN is composed of, for example, the flat rear surface KN of the main body 3 and the flat lower end surface KN2 of the head on which the antenna of the main body 3 is mounted, and is open toward the lower end in the longitudinal direction (up and down direction) of the main body 3. The battery 1 is mounted such that its front face faces the flat rear surface KN1 of the storage portion KN of the main body 3 and its upper face faces the flat lower end surface KN2 of the head. A rear cover RC is provided on the rear side of the head of the main body 3. A clip CP is fixed to the rear cover RC.

[0014] As shown in FIG. 3, the battery 1 has a rear surface portion formed so as to be uniform with the rear cover RC as the rear surface of the mobile radio device when mounted in the storage portion KN of the main body 3 (see FIG. 1). In addition, the battery 1 has left and right side surface portions and a lower surface portion formed so as to be uniform with the left and right side surfaces and the lower surface of the mobile radio device when mounted.

[0015] The battery 1 has, on its left and right side faces, two pairs of spaced-apart battery hook-shaped portions 5 (second engaging portions) that are located near the flat back surface KN1 of the storage portion KN of the main body 3 when the battery is mounted. Each of the battery hook-shaped portions 5 is a fixed hook that protrudes inside the left and right side faces of the battery 1. The tip of each of the battery hook-shaped portions 5 extends upward in parallel with the flat back surface KN1 (see FIG. 1) of the storage portion KN of the main body 3.

[0016] As shown in FIGS. 1 and 3, the battery 1 further has, inside the back surface portion at the uppermost part of the battery 1, two fixing claws 9 (first engaging portions) that each protrude so as to be located near the lower end of the rear cover RC when the battery is mounted. Each of the two fixing claws 9 is a tapered hook having a downward plane P and a taper T of an upward inclined plane.

[0017] Turning over, as shown in FIG. 2, on the flat back surface KN1 of the storage portion KN of the main body 3, there are formed main body hook-shaped portions 6 (second engaged portions) that respectively face and engage with the battery hook-shaped portions 5 when the battery 1 is mounted (see FIG. 1). Each of the main body hook-shaped portions 6 is erected on the side face portion of the storage portion KN (that is, the portion where the battery hook-shaped portions 5 of the left and right side faces of the battery 1 are located when the battery 1 is mounted). The main body hook-shaped portions 6 are two fixed hooks that lock the battery hook-shaped portions 5. The tip of each of the main body hook-shaped portions 6 extends downward in parallel with the flat back surface KN1 (see FIG. 1) of the storage portion KN of the main body 3. Each of the main body hook-shaped portions 6 guides and locks each of the engaging battery hook-shaped portions 5 of the battery 1 to a predetermined position at the lower part of the back surface (see FIG. 1).

[0018] (Movable locking portion 10 (first engaged portion)) Furthermore, as shown in Figures 2, 4, and 5, the upper part of the storage section KN of the main body 3, i.e., the lower end flat surface KN2 of the head, has two movable locking parts 10 formed on the main body 3 that engage with and lock onto the two fixing claws 9 when the battery 1 is installed (see Figure 1), and these are covered by the rear cover RC. In other words, each of the movable locking parts 10 is an elastic movable hook that locks onto each of the two fixing claws 9 of the battery 1 and can release the lock.

[0019] Furthermore, the rear cover RC of the head portion of the main body 3, above the storage portion KN, has a clip CP that is fixed and extends from between the two movable locking portions 10 so as to partially cover the battery 1. The rear cover RC may be directly connected to the main body 3. As shown in Figures 4 and 5, the clip CP is a support member that supports the main body 3 by sandwiching an object to be held, such as a belt, between the tip of the clip CP and the battery 1.

[0020] Figures 6 to 10 show a schematic enlarged cross-sectional view of the part where the main body 3 and battery 1 have been partially cut along the line xx in Figure 5.

[0021] Each of the movable locking parts 10 has a pressing part BTN (release button) located adjacent to each of the two fixed claws 9 when locked, and exposed from the rear cover RC, as shown in Figure 6. Each of the pressing parts BTN is provided to release the lock of each of the fixed claws 9, and is configured so that the lock is released and the battery 1 can be removed when the user presses the pressing part BTN at once with their finger or the like.

[0022] As shown in Figure 6, the movable locking part 10 is a lever member supported by a pivot point 11 at the tip of a frame FL erected from the main body 3, extending downward from the pivot point 11 beyond the pressing part BTN, and equipped with a tapered hook TF at its tip. The movable locking part 10 rotates about the pivot point 11 as its central axis and locks the fixing claw 9 of the battery 1 with the tapered hook TF. The movable locking part 10 is usually positioned parallel to the main body 3, facing it from the pivot point 11. The pressing part BTN operates the movable locking part 10 to allow the tapered hook TF to move relative to the main body 3.

[0023] The tapered hook TF of the movable locking part 10 has an upward-facing plane P1 and a downward-facing tapered plane T2. When the fixed claw 9 is locked, the upward-facing plane P1 of the tapered hook TF forms a contact surface 13 with the downward-facing plane P of the fixed claw 9.

[0024] A spring 12 is installed between the movable locking part 10, which is separated from the frame FL, and the device body 3. When no pressing operation is performed on the pressing part BTN, as shown in Figure 6, the movable locking part 10 is pushed in the direction B by the spring 12, and the tapered hook TF at the tip is held in contact with the fixing claw 9 of the battery 1. The spring 12 acts to elastically push back the movable locking part 10 when the movable locking part 10 approaches the device body 3.

[0025] In the held state of battery 1, as shown in Figures 1, 4, and 5, the battery hook-shaped portion 5 of battery 1 and the main body hook-shaped portion 6 on the device body side are engaged. In this state, the movement direction of battery 1 is restricted to only the C direction, as shown in Figure 6. Also, in the held state of battery 1, the fixing claw 9 of battery 1 and the movable locking portion 10 are in contact at the contact surface 13. The contact surface 13 is perpendicular to the removal direction of battery 1, i.e., the C direction, and the perpendicular line drawn from the center of the pivot point 11 to the contact surface 13 is parallel to the C direction. In this positional relationship, even if force is applied to battery 1 in the C direction, the movable locking portion 10 at the contact surface 13 prevents the battery 1 from moving. Therefore, when battery 1 is engaged with the movable locking portion 10 at the contact surface 13, it cannot be moved in any direction relative to the device body 3 and its position is maintained. The two movable locking portions 10 have the same structure and are located at the same position when viewed from the side. Furthermore, the two movable locking parts 10 operate independently of each other. Thus, in this embodiment, each of the two fixed claws 9 and each of the two movable locking parts 10 have flat surfaces P, P1 that contact and lock with each other as hook-shaped parts.

[0026] (Operation description) Figures 7 and 8 show the operation for removing the battery 1. To remove the battery 1 from the device body 3, simultaneously push the two pressing parts BTN of the movable locking part 10 in the D direction with your fingertip (not shown) from the back of the device. At this time, the spring 12 compresses, and the movable locking part 10 rotates in the D direction around the pivot point 11, releasing the contact between the tapered hook TF of the movable locking part 10 and the fixed claw 9 at the contact surface 13. As the tapered hook TF of the movable locking part 10 rotates in the D direction, a gap is created above the fixed claw 9. By using this gap and applying force in the C direction with the pad of the finger (not shown) that pushed in the movable locking part 10, the released battery 1 can be moved in the C direction and removed, as shown in Figure 8. Since the two movable locking parts 10 operate independently, the operation to release the locking requires operating both movable locking parts 10 simultaneously. Operating only one of them will not release the engagement of the other, and therefore the battery 1 cannot be removed.

[0027] Figure 8 shows the operation during battery installation. When installing the battery 1 into the device body 3, as shown in Figure 8, the battery 1 is moved in the E direction along the storage section KN of the device body 3 so that the hook-shaped parts of the device body 3 and the battery 1 (the tapered hook TF of the movable locking part 10 and the fixed claw 9) of the device body 3 and the battery 1 catch on each other. As shown in Figure 9, during the movement operation, the sloping taper T on the upper part of the fixed claw 9 comes into contact with the taper T2 of the tapered hook TF of the movable locking part 10. Furthermore, as the battery 1 moves in the E direction, as shown in Figure 10, the pressing part BTN of the movable locking part 10 rotates in the D direction around the pivot point 11 and is pushed away. When the battery 1 is moved further in the E direction and reaches the fixed holding position, as shown in Figure 6, the movable locking part 10 rotates in the B direction due to the pressure of the spring 12 and returns to its normal position, and finally the tapered hook TF of the movable locking part 10 locks onto the fixed claw 9, thereby fixing and holding the battery 1. Since the two movable locking parts 10 are located in the same position when viewed from the side, the above operations are performed simultaneously on both movable locking parts 10 when attaching the battery 1.

[0028] (Explanation of effects) As described above, according to the first embodiment, by providing a fixing claw 9 at the upper end of the battery 1 and a movable locking part 10 made of resin or metal on the side of the adjacent device body 3, it becomes possible to fix and hold the battery 1 without providing a holding structure consisting of a locking member, recess, etc. at the lower part of the device body 3 and the battery 1, thereby reducing the height dimension of the portable radio and making the device smaller.

[0029] Furthermore, by providing two movable locking parts 10, and designing the battery 1 so that it cannot be removed unless both are operated simultaneously, the battery 1 will not come off even if one of the movable locking parts 10 is operated incorrectly, thus preventing it from falling out.

[0030] Furthermore, by positioning the movable locking part 10 adjacent to the upper end of the battery 1, it becomes possible to remove the battery 1 by using the gap created when the movable locking part 10 is pressed with a fingertip to place the pad of a finger on the upper end of the battery 1, resulting in improved battery removal operability.

[0031] Furthermore, since the main body 3 has a clip CP that extends above the storage section KN and partially covers the battery 1 from between the two movable locking parts 10, even with the clip CP in place, the two movable locking parts 10 prevent the battery 1 from becoming detached and falling out due to malfunction.

[0032] (Second example) (Described the configuration and operation) In the first embodiment, an example was described in which the movable locking portion 10 is formed by a lever member having a frame FL from the main body 3, a pressing portion BTN supported by a pivot point 11, and a tapered hook TF, and a spring 12 supporting it. However, as shown in Figures 11 and 12, the second embodiment is the same as the second embodiment except that the movable locking portion 10, which is a cantilever spring with a tapered hook TF at its tip, is integrally formed on the wall of the rear cover RC, instead of the lever member and spring 12.

[0033] As shown in Figure 11, each of the movable locking portions 10, which have a tapered hook TF at its tip, is formed by cutting out a portion of the wall of the rear cover RC with slits SL that extend downward parallel to each other.

[0034] Each of the movable locking parts 10, which has a tapered hook TF at its tip, elastically deforms when pressed by a finger or the like against the adjacent pressing part BTN. When this pressing force is removed, each of the movable locking parts 10 returns to its original shape, and as shown in Figure 12, it plays a supporting role in locking the fixing claw 9 of the battery 1.

[0035] In the second embodiment, the operation is the same as in the first embodiment, except that the number of components of the movable locking part 10 is reduced.

[0036] (Explanation of effects) In this embodiment, the same effects as in the first embodiment are achieved, and furthermore, the number of components of the movable locking part 10 can be reduced.

[0037] Furthermore, in the above embodiments of the present invention, the movable locking part 10 of the main body 3 and the fixing claw 9 of the battery 1 are arranged on the back side of the portable radio. However, as a variation, the movable locking part 10 of the main body 3 and the fixing claw 9 of the battery 1 may be arranged on the left and right sides of the portable radio. Also, the number of locations where the movable locking part 10 of the main body 3 and the fixing claw 9 of the battery 1 are installed may be two or more.

[0038] Although the first and second embodiments described examples of application to portable wireless devices, the invention is also applicable to devices with removable batteries, such as mobile phones. Furthermore, the present invention includes any combination of the above embodiments and modifications. [Explanation of Symbols]
