Description

The present invention relates to a battery lid structure for assembling a battery lid to a housing.

Conventionally, in a mobile terminal or the like, as a fixing structure of a battery lid assembled to a housing so as to cover a battery housing portion in which a battery is housed, a claw portion or the like provided on the lower end side in the longitudinal direction of the battery lid is used to engage the housing. In many cases, a lock structure is adopted in which the lock lever of the housing is slid and locked to a hook or the like provided on the upper end side in the longitudinal direction of the battery lid in a state of being engaged with the joint portion or the like.

For example, in the optical information reader disclosed in Patent Document 1 below, a cylindrical secondary battery is adopted as a battery unit in order to improve the grip feeling and the like, and the battery storage unit in which the battery unit is housed is adopted. The battery lid that closes the battery lid is attached to the housing by pressing the lower end side in the longitudinal direction with the lock button of the lower case slid on the upper end side in the longitudinal direction while the lower end side in the longitudinal direction is engaged with the lower case.

By the way, the cylindrical secondary battery as described above tends to have a longer length in the longitudinal direction than the square secondary battery, and when the total length of the battery becomes long in this way, it covers the battery. The total length of the battery lid is also long. For this reason, in a battery lid structure in which the battery lid engages with the housing on the lower end side in the longitudinal direction and is slid-locked on the upper end side in the longitudinal direction, the longer the battery lid is, the more likely it is that warpage or the like occurs. The engaged part is likely to come off due to warpage or the like. In order to make it difficult for the engaging portion to come off even if the battery lid is warped or the like, it is necessary to increase the size of the engaging portion, which causes a problem that the housing becomes large. Such a problem may occur not only in a cylindrical secondary battery but also in a secondary battery having another shape such as a square type.

As a result, the battery lid 70 is assembled to the housing 11a by utilizing the one-side lid engaging portion 71a and the other-side lid engaging portion 71b on both sides in the lateral direction thereof.

Then, from the state in which the battery lid 70 is assembled to the housing 11a as described above, the lever main body 41a and the engaging portion 42a of the fixing member 16a and the lever main body 41a of the fixing member 16b are engaged by pressing the levers 40a. By pushing the joint portion 42a inward against the urging by the spring 61a, the engagement between the engaging portion 42a and the elongated hole 73 is released. As a result, the battery lid 70 can be removed from the housing 11a.

Even in this case, since the engaging portions with the housing 11a are provided on both sides of the battery lid 70 in the lateral direction, compared with the case where the engaging portions with the housing 11a are provided in the longitudinal direction of the battery lid. Therefore, the total length (length in the longitudinal direction) of the battery lid 70 can be shortened.

Even in this case, since the engaging portions with the housing 11b are provided on both sides of the battery lid 70b in the lateral direction, compared with the case where the engaging portions with the housing 11b are provided in the longitudinal direction of the battery lid. Therefore, the total length (length in the longitudinal direction) of the battery lid can be shortened. Further, since the engaging portion on one side and the engaging portion on the other side can be brought close to each other, the engaging portion does not easily come off due to the warp of the battery lid 70b or the like, so that the engaging portion is formed. It does not increase in size. When the battery lid 70b is removed from the housing 11b, the one-side elastic portion 81a is elastically deformed so that the engagement between the one-side extension portion 82a and the step portions 91a and 92a is released, and the other side is elastically deformed. Since the elastic portion 81b on the other side may be elastically deformed so that the engagement between the extension portion 82b and the step portions 91b and 92b is released, the battery lid 70b can be easily removed. Therefore, even when the total length of the battery lid 70b is long, it is possible to realize the battery lid structure 1b that can suppress the increase in size of the housing 11b.

In particular, the direction in which the one-side extending portion 82a is urged by the one-side elastic portion 81a and the direction in which the other-side extending portion 82b is urged by the other-side elastic portion 81b are opposite, so that, for example, a drop is made. Even if an external force such as the above acts on the one-side extension portion 82a in the engagement disengagement direction, the external force acts on the other-side extension portion 82b in the engagement direction. It can be made difficult to come off from the housing 11b.
