Description

  The present invention relates to a mounting structure for a battery housing lid of a portable device, and more particularly, to a locking means at a position where the battery housing lid closes the battery housing.

  An example of a portable CD player to which a conventional battery housing cover mounting structure is applied will be described with reference to FIGS. A cover 2 is rotatably supported on the resin case member 1 shown in FIGS. 9 and 10. When the cover 2 is rotated to a position covering the upper surface 1 a of the case member 1, the cover 2 is fixed to the cover 2. The locking piece 4 is locked by the lock mechanism 3 provided on the case member 1, and the cover 2 is fixed at a position covering the upper surface 1 a of the case member 1.

  The turntable 5 fixed to the rotating shaft of the disk motor fixed inside the case member 1 supports and rotates the disk (CD). The signal recorded on the disk is read while the optical pickup 6 disposed on the case member 1 moves while the disk is rotated, and the recording on the disk is reproduced.

  As shown in FIG. 10, a battery housing part 1 c is formed in the case member 1, and the battery housing part 1 c is closed by a battery housing part lid 11. That is, the rotation shaft provided at one end of the battery housing lid 11 is rotatably supported by the case member 1, and when the battery housing lid 11 is closed, the fixing shaft provided at the tip of the battery housing lid 11 is fixed. The hook 11 a is locked to the case member 1.

  In the battery housing lid mounting structure described above, when the battery housing lid 11 is warped so as to protrude upward as shown in FIG. 11, the recording surface of the rotating disk 12 is lifted from the upper surface 1a of the case member 1 and rotated. There was a risk of touching and damaging the disc. For this reason, the battery housing lid must be made of a material such as metal that is not easily warped, which increases the manufacturing cost. If the battery housing cover is made of a normal resin member, the battery housing cover tends to warp due to a compressive load when the fixing hook 11 a is locked to the case member 1.

  Further, even when the fixing hook 11a is not completely locked to the case member 1, the battery housing portion cover 11 may be lifted and damage the disc. If the recording surface of the disk 12 is damaged, the disk may not be able to be reproduced in the worst case.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a battery for a portable device that does not have a risk of floating above the upper surface of the case member even if the battery housing cover is not made of an expensive material. It is in providing the attachment structure of a accommodating part lid | cover.

A flat holding surface is provided, and the ribs of the ribs are moved by moving the battery housing cover in a direction parallel to the upper surface of the case member and perpendicular to the rotation shaft in a state where the battery housing portion is closed and the battery housing portion is closed. The contact flat surface enters under the pressing surface, and the battery accommodating portion lid is locked by the pressing surface.

  In the battery housing lid mounting structure of the portable device, the case member is provided with a notch through which the rib passes when the battery housing lid rotates.

  Further, in the battery housing cover attachment structure of the portable device, an inclined portion that is guided so as to enter the notch formed in the case member is provided on the rib having the contact plane.

  In the battery housing lid mounting structure of each portable device, a battery housing lid support rib for supporting the battery housing lid from below is provided on the case member.

  Further, in the battery housing lid mounting structure of each portable device, it is possible to take out the battery accommodated in the battery housing by extending along the bottom and side surfaces of the battery housing and pulling one end. The elastic plate member is configured to urge the battery housing cover in the opening direction.

  Further, in the battery housing cover attachment structure of each portable device, an interference rib protrudes from a cover that is rotatably attached to the case member and covers an upper surface of the case member, and the battery housing cover is locked. When there is no cover, the interference rib interferes with the battery housing cover and the cover is not closed.

  Further, in the battery housing portion lid mounting structure of each portable device, a convex portion that is higher than the upper surface of the case member is formed in a portion of the battery housing portion lid that is farthest from the center of the case member.

  According to the battery housing cover attachment structure of the present invention, since the battery housing cover is reliably prevented from warping, the battery housing cover can be formed of a general resin rather than an expensive material that does not warp. Manufacturing cost is reduced.
