Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a battery lid lock structure, and more particularly, to a battery lid lock structure that is used in portable information devices and the like and can improve battery replacement workability and prevent battery dropout due to erroneous operation.
[0002]
[Prior art]
In recent years, various types of portable information devices such as PDAs (Personal Digital Assistants) specialized for functions such as schedule management and mobile phones capable of sending and receiving e-mails have been developed.
[0003]
These portable information devices require a relatively large capacity power source as a driving power source for a backlight of a liquid crystal display panel, a radio wave transmitting / receiving device and control device, a backup device for various data, and the like.
[0004]
As these power supplies, normal dry batteries are also used, but a considerable number of batteries are required to obtain sufficient capacity and they are consumed quickly. Therefore, they can be charged in consideration of downsizing of devices and cost performance. Relatively large-capacity secondary batteries (NiH batteries, lithium ion batteries, etc.) are generally employed.
[0005]
This secondary battery has a life of about 1 to 3 years in normal use, so frequent battery replacement is unnecessary, and data stored when the user inadvertently removes the secondary battery. The battery cover of the secondary battery compartment in portable information devices is generally screwed, or specially treated by manufacturers or dealers. In many cases, a lock structure is used that cannot be opened unless tools or tools are used.
[0006]
[Problems to be solved by the invention]
However, portable information devices vary in use frequency depending on the user, and in the case of a user with high use frequency, the secondary battery has a period shorter than the normal battery life (1 to 3 years) (for example, about half a year). The life of the product may run out.
[0007]
In addition, there is a so-called memory effect peculiar to the secondary battery that the battery life is shortened if the battery is repeatedly charged in a state where it is not completely discharged. The life of the secondary battery is usually normal depending on how the portable information device is charged. May become shorter.
[0008]
For this reason, it is assumed that the secondary battery will run out much faster than the product life of the portable information device. In such a case, it is necessary to receive battery replacement services from manufacturers and dealers one by one. It is very inconvenient for users. For this reason, in consideration of the product characteristics of portable information devices used on a daily basis, it is preferable that the secondary battery itself be treated as a replaceable part, and the battery can be replaced on the user side.
[0009]
On the other hand, with a lock structure that allows the user to inadvertently remove the secondary battery, as described above, data stored when the secondary battery is accidentally removed may be lost. There is a risk of inviting.
[0010]
The present invention has been devised to solve the above-mentioned problems, and in a portable information device, a battery lid lock capable of achieving both improvement in battery replacement workability and prevention of battery dropout due to erroneous operation. Its purpose is to provide a structure.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a battery that is provided on the main body side of the apparatus (mail terminal machine M) and that removably covers a battery housing part (S) that houses one or more batteries (10). In the lock structure of the lid (1), the battery lid is adapted to be attached to and detached from the device main body on the opening of the battery storage portion, and the battery lid is adapted to be attached to and detached from the device main body. A hook portion (1b) that engages with a first engagement portion (20) formed in the vicinity of the battery housing portion on the main body side protrudes from the distal end side (1B) of the battery lid and is translated. An engagement piece (6) that engages with a second engagement portion (30) formed on the rear end side of the battery housing portion on the main body side is formed on the rear end side (1C) of the battery lid at the time. The first engaging portion includes a through hole (2) formed by drilling a back surface of the body-side casing, and the hook portion A contact portion (1c) is formed at the tip so as to face the through hole when the hook portion is engaged with the first engaging portion, and a protrusion (pen nib) is formed from the outside of the through hole. when P1) is inserted, before notated click portion and said contact portion is pressed, which was constructed as engagement with the with the hook portion first engagement portion is released is there.
[0012]
Thus, unless it is the the through hole by inserting the projections based on the intention of the operator of depressing the full-click section and contact section operation, since the engagement of the battery cover and the apparatus body is not released, It is possible to avoid a situation where the battery lid is removed due to an erroneous operation and the battery falls off.
[0013]
Further, when the battery replacement, the battery cover by a simple operation that without using special jigs or tools such as, by inserting a suitable projection into the through-hole depressing the off click portion and the contact portion Since the battery lid can be removed by releasing the engagement between the main body and the apparatus main body, the user can easily replace the battery.
[0014]
Two or more hook portions are formed in the longitudinal direction of the tip portion of the battery lid, and the first engagement portion corresponding to each hook portion is formed on the device main body side. It is good to do so.
As a result, the battery lid can be reliably attached to the apparatus main body side, and rattling or the like of the battery lid can be prevented.
Also, when removing the battery cover, for all two or more locations of the hook portion, so unless the battery cover trouble releasing perform operations that by inserting the protrusion into the through hole depressing the off click portion and the contact portion The situation where the battery is accidentally removed can be avoided more reliably.
[0015]
The through hole may have a diameter that allows the pen tip of the writing instrument to be inserted. Accordingly, the battery lid can be removed with a pen tip of an appropriate writing instrument without requiring a special instrument, so that the convenience of battery replacement by the user can be improved.
[0016]
Furthermore, the hook portion, the engagement piece, and the battery lid main body may be integrally formed of synthetic resin.
That is, by using, for example, as a impact resistant resin synthetic resin (ABS resin), can also avoid the occurrence of cracks and breakage due to fatigue by repeating the operation of pressing down the full click portion and the contact portion, Durability can be increased.
