Abstract

PROBLEM TO BE SOLVED: To provide a battery housing unit, which can naturally absorb a dimensional error so as to previously prevent the generation of looseness of a cover body even in the case where a little of dimensional error is generated in the manufacturing process and of which cover body can be easily opened and closed. SOLUTION: This battery housing unit includes a battery housing recessed part 2, which is formed into the nearly quadrangle with plane view and which is formed in a case main body 1, and a cover body 3 elastically fitted in the open surface of the battery housing recessed part 2 freely to be disconnected, and both end parts of the bottom surface of the battery housing recessed part 2 are formed with elastic tongue pieces 4a, 4b, which rise upward. Leg pieces 5a, 5b, which elastically contact with the elastic tongues 4a, 4b, are extended from the lower surface of the cover body 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a battery storage portion in an electric device such as a portable audio device, and more particularly to a lid mounting mechanism for closing an opening surface of the storage portion.

[0002]

2. Description of the Related Art Conventionally, as a battery housing portion formed in a casing of an audio device, there is, for example, one shown in FIG. The battery housing portion includes a lid body 13 having a cushion on the opening surface of a battery housing recess 12 formed in the case body 11.
Is detachably elastically fitted through the left and right engaging claws 14.

[0003]

In this conventional structure, the lid 13 is formed only by the elastic force of the left elastic bending piece 15 formed on the case body 11 and the elastic engaging force of the engaging claw 14. Since it is elastically held, if there is an error such that a gap is formed between the left and right engaging portions A and B in the manufacturing process, the gap will cause rattling of the lid as it is. . It is extremely difficult to completely eliminate such a manufacturing error in the ordinary press working of metal plates and resin molding. Therefore, in the past, it was necessary to perform severe part dimension management such as elimination of defective products, which was a factor of cost. Further, if the elastic bending piece 15 of the case body is lengthened downward to increase the elastic force, some errors can be absorbed, but it becomes very difficult to attach and detach the lid.

Therefore, a main object of the present invention is to naturally absorb even a slight dimensional error in the manufacturing process to prevent rattling of the lid body and easily open and close the lid body. The purpose of the present invention is to provide a structure of a battery storage unit that can be used.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, in the structure of the battery accommodating portion according to the present invention, the battery accommodating concave portion 2 formed in the case body 1 and having a substantially square shape in plan view,
A lid 3 detachably elastically fitted to the opening surface of the battery housing recess, and elastic tongues 4a, 4b that are raised upward are formed at both ends of the bottom surface of the battery housing recess 2. The leg pieces 5a, 5b elastically contacting the tongue pieces 4a, 4b are extended from the lower surface of the lid body 3.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the structure of the battery housing shown in the embodiment shown in FIGS. 1 and 2, the battery housing recess 2 formed in a synthetic resin case body 1 of an audio device or the like and having a substantially rectangular shape in plan view, and the battery The lid 3 is detachably elastically fitted to the opening surface of the storage recess. The lid 3 has one engaging claw 6a on the lower surface at the left end and two engaging claws 6b on the lower surface at the right end.
Are provided, and the engaging pieces 7a and 7b that fit into these engaging claws are provided.
Is formed on the opening edge of the battery housing recess 2. Of these engagement pieces, the left engagement piece 7a is curved slightly downward to give an appropriate elastic force, and is formed so as to elastically engage with the engagement claw 6a of the opposing lid body. ing.

Further, elastic tongues 4a and 4b are formed at both ends of the bottom surface 8 of the battery accommodating recess 2 so as to bulge upward, and the leg pieces 5a and 5b elastically contact the elastic tongues 4a and 4b when the lid is closed. Is extended from the lower surface of the lid 3.
In the figure, 9 is a cushion material attached to the lower surface of the lid, 10
Is a battery housed in the battery housing recess 2, and 11 is a seating surface formed at the opening edge of the battery housing recess 2 for receiving the outer edge portion of the lid.

In the above structure, when the lid 3 is mounted in the battery housing recess 2, the lid 3 is always elastically upward by the elastic tongues 4a and 4b formed on the bottom surface of the battery housing recess 2. It is pushed up, and therefore, the engaging claw 6 of the lid body is manufactured.
Even if a gap is formed between the a and 6b and the case-side engaging pieces 7a and 7b, it is absorbed by the elastic pushing-up force and rattling does not occur.

Although a representative embodiment of the present invention has been described above, the present invention is not necessarily limited to the structure of the above embodiment. For example, the engaging claws 6a and 6b described above
The numbers of the engaging pieces 7a and 7b, the elastic tongues 4a and 4b, and the leg pieces 5a and 5b are not specified. Further, the material of the case body 1 including the lid 3 and the battery housing recess 2 is not limited to the synthetic resin and may be a metal. In addition, in the present invention, it is needless to say that the present invention can be carried out by appropriately changing the configuration within the scope of providing the components and having the effect.

[0010]

Since the present invention is constructed as described above, when the lid is closed, the lid is always elastically pushed upward by the elastic tongue formed on the bottom surface of the battery housing recess. As a result, even if a gap is created between the engaging claw of the lid and the engaging piece of the case due to a mistake in manufacturing or due to deformation or distortion of the material, the elastic push-up force causes absorption and rattling occurs. In this way, the battery can be stably held, and severe effects such as severe quality of parts and dimensional control can be omitted.
