Next, a battery cover structure of a portable electronic device according to an embodiment of the present invention will be described with reference to the drawings using a mobile phone as an example.
(Description of configuration)
FIG. 1 is an exploded perspective view showing a mobile phone housing and a battery cover structure according to the present embodiment. FIG. 2 is a cross-sectional view showing a connection structure of a battery cover, and FIGS. 2A and 2B are cross-sectional views taken along line II and II in FIG. 1, respectively (enlarged view). It is.
[0012]
The battery cover structure according to the present embodiment is applied to a mobile phone having a folding structure including a hinge shaft 1. The mobile phone main body (housing) 2 having a folding structure is composed of two housings hinged together, each housing being inside in a folded state and being folded with a front case 22 having a main operation unit, a display unit and the like on the front surface. A rear cover 21 having a structure on the rear side that is outside in a folded state and capable of storing a battery is combined. Both housings have a structure in which ends of a front case 22 are connected to each other by a hinge shaft 1, for example.
[0013]
The rear cover 21 having the battery housing portion 3 of the mobile phone main body 2 is formed of a flat or substantially flat rear shape on the back side of the mobile phone, and a side shape bent or curved to the side surface of the mobile phone, The battery housing portion 3 is formed on the outer surface side of the rear surface of the rear cover 21 and has a substantially rectangular concave structure in which the battery 7 is housed and the battery cover 8 is mounted. The battery 7 has a rectangular parallelepiped shape, and the battery cover 8 is a flat or substantially flat cover that covers the rectangular concave shape.
[0014]
The detailed structure of the battery housing portion 3 of the rear cover 21 is a rectangular concave shape formed inside thereof as shown in FIG. 1 and having a predetermined depth having a shape corresponding to the three-dimensional shape of the rectangular parallelepiped battery 7. 31 and a step portion 32 corresponding to the thickness of the battery cover 8 from the outer surface of the rear cover 21 around (outside) the portion 31, and the step portion 32 is mechanically coupled to a nail provided on the battery cover 8 described later. For this purpose, a plurality of engaging portions 4 and 5 and a fitting portion 6 for preventing the battery cover 8 from coming off are formed.
[0015]
On the other hand, the detailed structure of the battery cover 8 is such that the battery 7 is mounted on the step portion 32 after the battery 7 is stored in the recess 31 of the rear cover 21 and can close the rectangular recessed shape. It has engaging claws 9, 10 and a fitting claw 11, respectively, which are coupled to the parts 4, 5 and the fitting part 6.
[0016]
Here, the engaging portion 4 of the rear cover 21 has a recess on the step portion 32 provided on the end side of the battery cover 8 opposite to the fitting claw 11 as shown in FIG. The depression has an upper slope 4a and a lower slope 4b which are engaged with the engagement claws 9 of the battery cover 8. A projection is formed on the depression, and the engagement claws 9 of the battery cover 8 are engaged with the rear cover 21. A lower slope 9a having the same inclination as the lower slope 4a of the portion 4 and an upper slope 9b engaging with the upper slope 4b of the engaging portion 4 are formed, and the respective slopes 9a, 4a of the battery cover 8 are formed. The battery cover 8 has an inclined surface shape that generates a force (sliding force) that the battery cover 8 slides and moves toward the engagement claw 10 due to pressing from the periphery of the upper outer surface of the engagement claw 9 during engagement. When the battery cover 8 is engaged, the respective inclined surfaces 9b and 4b have an inclined surface shape having a lock function of preventing the battery cover 8 from being detached upward.
[0017]
The engaging portion 5 has a recess on the step portion 32 as shown in FIG. 2A, and the recess is parallel to the longitudinal direction of the rear cover 21 which engages with the engaging claw 10 of the battery cover 8. In addition, the engaging claw 10 of the battery cover 8 can be mounted by sliding with the above-mentioned protrusion of the engaging portion 5 of the rear cover 21, and has a cross-sectional shape perpendicular to the plane of the battery cover 8 and in the sliding direction. It has an L shape protruding in the sliding direction.
[0018]
Further, the fitting portion 6 of the rear cover 21 has a vertical opening provided in the step portion as shown in FIG. 2B, and the fitting claw 11 of the battery cover 8 It is provided at the end (lower surface) opposite to the dovetail 9 and slides when the battery cover 8 is mounted, slides outside the step of the opening of the fitting portion 6, and is inserted while bending downward, It has a projection shape (return member) having an inclined portion whose tip is locked by the step inside the opening.
(Description of operation)
[0019]
Next, mounting and removing operations of the battery cover according to the present embodiment will be described.
FIG. 3 is a diagram showing a procedure for mounting the battery cover 8 according to the present embodiment. The battery 7 is stored in the battery storage portion 3 of the rear cover 21 of the mobile phone, and the engagement claws 9 and 10 of the battery cover 8 are fitted to the engagement portions 4 and 5 of the rear cover 21 on the fitting portion 6 side (not shown). After sliding (FIG. 2A), the outer surface (upper surface) of the engaging claw 8 of the battery cover 8 is pressed, so that the battery cover 8 is slid by the inclined surfaces 9a and 4a. The engaging claws 9 are slid to the fitting portion 6 to engage the engaging claws 9 and 10 with the engaging portions 4 and 5 (FIG. 2B), and the fitting claw 11 is fitted to the fitting portion 6. Locking prevents movement in the direction opposite to the sliding direction.
[0020]
FIG. 4 is a diagram showing the state of attachment of the battery cover. As shown in FIG. 4, when the battery cover 8 is mounted, all the ends (peripheral portions) of the battery cover 8 are located on the steps 32 of the rear cover 21, and the upper surface of the battery cover 8 is flush with the rear surface of the rear cover 21. (FIG. 2C).
[0021]
FIG. 5 is a diagram showing a procedure for removing the battery cover 8 according to the present embodiment. When removing the battery cover 8, the vicinity of the fitting claw 11 of the battery cover 8 is pressed and bent from the outer surface, and the tip of the fitting claw 11 is removed from the inside of the step of the fitting portion 6 of the rear cover 21 ( 2 (b)), the battery cover 8 is slid in the direction opposite to the sliding direction at the time of mounting shown in FIG. 4 (FIG. 5 (a)), and the fitting claws 11 from the fitting portion 6 are removed. The lower slope 9b of the corner of the dovetail 9 is moved along the slope 4b of the engaging portion 4 of the rear cover 21, and the battery cover 8 is lifted obliquely upward to release the fixing from the engaging portions 4, 5 to release the battery. The cover 8 is removed (FIG. 5C).
[0022]
In the above embodiment, the structures of the engaging portion 4 and the engaging claw 9 and the structures of the fitting portion 6 and the fitting claw 11 can employ various mechanisms. Further, as the inclined surface shapes of the engaging portion 4 and the engaging claw 9, the structures of the inclined surfaces which are substantially parallel to each other are shown, but it is apparent that the inclined shape can also be constituted by the R shape (the convex shape of the sliding surface). is there.
[0023]
【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, all four sides of a battery cover are surrounded by a rear cover, and since there is no surface (shape) which goes around to the side surface of a housing | casing, the structure which is not hit by the corner | angular surface of a battery cover etc. by a fall directly, and is strong against breakage. Is possible.
[0024]
In particular, by configuring the battery cover to be removed while being lifted diagonally upward, the battery cover can be opened and closed in a region where all four sides of the battery cover are surrounded by the rear cover. Since it is not necessary to increase the thickness of the surface and the thickness of the side wraparound portion, it is possible to reduce the thickness of the device and reduce the size (width direction) of the device.
