Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery accommodating structure suitable for facilitating battery replacement in a device operating with a battery as a power source.

[0002]

2. Description of the Related Art The number of devices using a battery as a DC power source is increasing, and the device is becoming smaller. With the shift to miniaturization, the volume and structure of the battery storage section that stores the batteries is also limited, and for example, the main unit with an absence recording function of a cordless phone is also shifting to miniaturization. The space for taking out batteries is also narrowed, and it is becoming difficult to take out the stored batteries. As shown in FIG. 5, the conventional battery housing unit connects the battery 5 by providing a pair of connection parts 6 electrically connected to the battery 5 on the inner wall of the battery housing unit 1 facing the electrodes of the battery 5. Bottom 22 between parts 6-6
It is seated on and is covered with a lid 9 to which a pressure contact cushion 8 made of a sponge material is adhered. In such a structure, the battery 5 surely contacts the pair of connecting portions 6 electrically connected to the battery 5 on the inner wall of the battery housing portion 1 facing the electrode of the battery, and surely seats on the bottom portion 2. Then, if a stable DC voltage can be supplied, the basic functions will be fulfilled. Therefore, the battery housing structure lacks the consideration for simplifying the battery removal. As a general method of taking out a battery, it is often picked up with a fingertip or scratched with a nail, but as shown in FIG. 7, an auxiliary tool for pulling out the battery, for example, a rubber band or a string for pulling the battery is attached to the battery. In some cases, it is possible to deal with it.
In the case of a rubber ring or the like, these take-out aids may be disconnected during repeated use for battery replacement.

[0003]

In a device operating with a battery as a power source, the battery must be replaced due to the life of the battery. However, when the battery is replaced, a connecting portion provided on the inner wall of the battery housing 1 is required. Since one side of 6 uses an elastic member, the elastic force works and it is in a pressure contact state, and it is very difficult to pick up the battery because the space for taking out the battery is narrow. Often difficult. As mentioned above, although there is a problem with the auxiliary device for taking out the battery, it is expected that devices operating with the battery as a power source will be further miniaturized. The design is becoming more frequent. With the current technology, it is difficult to take out the stored battery when exchanging the battery, and due to the progress of miniaturization, the taking out space is further restricted, which makes it more difficult to exchange the battery. It is expected that. Therefore, it is desirable that the battery can be easily taken out and the battery can be easily replaced.

[0004]

The present invention has been proposed as a means for solving the above-mentioned problems, and a part of the battery housed in the battery housing part is housed in the bottom of the battery housing part for housing the battery. There is provided a battery housing structure characterized in that a concave portion is provided. An electrode in which a connecting portion electrically connected to the battery is arranged on the inner wall of the battery housing portion facing the electrode of the battery, at least one connecting portion is made of an elastic member, and an elastic force is applied from the connecting portion of the battery. The battery storage structure is characterized in that a recess is provided on the side thereof and the battery storage section is capable of disposing and storing a plurality of batteries.

[0005]

According to the present invention, since the recess for temporarily storing a part of the battery is provided in the bottom of the battery storage part, the boundary between the flat part on which the battery is seated and the recess is formed as a fulcrum. By pressing the end of the battery stored in the storage part, part of the end of the battery pressed around the above fulcrum enters into the recess due to the lever principle and the opposite end floats up and the seesaw disengages. It becomes possible and the battery can be taken out easily.

[0006]

Embodiment 1 An embodiment of the present invention will be described with reference to the drawings. This case is the battery storage of the base unit with the absence recording function of the cordless phone, and the structure of the battery used is columnar and has positive or negative electrodes at both ends. It uses four AAA batteries. It is a battery storage structure. FIG. 1 is a schematic cross-sectional view of the battery housing of the present invention.
2 is a schematic cross-sectional view taken along the line AA of FIG.
FIG. 6 is a schematic cross-sectional view showing the action of detaching the seesaw of the battery when the end portion of the battery is pushed down when taking out the stored battery. In the figure, 2 is a bottom for seating a battery, 3 is a recess provided in the bottom for temporarily storing a part of the stored battery, 5 is a battery serving as a DC power source, and 6 is a battery facing the electrode of the battery. A pair of connection parts are electrically connected to the battery on the inner wall of the storage part, and 9 is a lid of the battery storage part. One of the factors that make it difficult to take out the stored battery is that the space for taking out the battery in the battery storage portion 1 is narrow and it is difficult to pick up the battery. Therefore, a part of the battery is
The battery can be taken out easily if it pops out high enough to be picked with your fingertips.

Paying attention to the structure of the bottom portion 2 of the battery housing portion 1 for housing the battery 5, the battery 5 is partially left floating.
The lever principle can be applied when the battery 5 is taken out by seating on the bottom part 2. Therefore, by providing the bottom portion 2 with the concave portion 3 for temporarily storing a part of the battery 5 stored in the battery storing portion when the battery is taken out, a boundary portion between the flat portion on which the battery 5 is seated and the concave portion 3 is provided. Is formed as a fulcrum 4. Specifically, a concave portion 3 for accommodating a part of the battery 5 accommodated in the battery accommodating portion is provided in the bottom portion 2 of the battery accommodating portion for accommodating the battery 5 having an electrode at least at one end, and the concave portion 3 is located on the concave portion 3 side. The end of the battery 5 is pushed down and the battery 5 is rotated around the fulcrum 4 by a seesaw to temporarily accommodate a part of the battery 5 in the recess so that the opposite side is lifted. Further, a connecting portion 6 electrically connected to the battery 5 is arranged on the inner wall of the battery housing portion 1 facing the electrode of the battery 5, and at least one connecting portion 6 is an elastic member such as a coil spring or a U-shaped plate spring. And the like, and the connecting portion 6 provides the battery 5
By providing the concave portion 3 on the side of the battery electrode to which the elastic force is applied, the elastic force of the elastic member of the connecting portion 6 acts when the end portion of the battery 5 located on the concave portion 3 side is pressed. When the seesaw rotates about the fulcrum 4 and the force of pushing out the battery 5 is added to the battery 5 at the same time, the battery 5 jumps up and the effect is enhanced. In addition, even when a plurality of batteries are arranged according to the power supply voltage of the equipment to be applied and the batteries can be stored, the recessed portion 3 is formed in the bottom portion 2.
The effect similar to the above can be obtained by providing (not shown). Further, as devices become smaller, there will be more constraints on the battery compartment, such as lighter weight and smaller volume. That is, if the opening area for taking out the battery of the battery housing portion is made sufficiently wide for the battery, the strength of the battery housing portion itself cannot be sufficiently secured, which is inconvenient. Therefore, if the battery can be easily taken out as in the present proposal, the eaves portion 7 can be formed as shown in FIG. 1 to solve the strength problem.

The position of the concave portion 3 provided in the bottom portion 2 of the battery housing 1 should be such that the boundary with the flat portion on which the battery sits, that is, the fulcrum 4 is formed, and the battery 5 can rotate the seesaw. Relatively viewed, one end, middle, both ends or a combination thereof may be considered (not shown).
May be a through hole (not shown). When actually replacing the stored battery 5, as shown in the schematic cross-sectional view of FIG. 3, the battery 5 is rotated around the fulcrum 4 by pressing the end of the battery 5 on the concave side. And battery 5
One side of will be easily lifted. The position of the fulcrum 4 in the battery accommodating portion, which is determined by the position of the recessed portion 3, allows the battery 5 to be firmly clamped and fixed by the lid 9 to which the bottom portion 2 and the pressure contact cushion 8 are adhered in a normal use state. From the viewpoint that the pushing force of the battery 5 can be made sufficiently small when the battery 5 is taken out, the best position is 1/3 to 1/2 of the length of the battery from the end of the battery.

[0009]

Example 2 The structure of the battery used is an example of a battery housing structure applied to a battery having a columnar shape and having positive and negative electrodes at one end. FIG. 4 shows a schematic sectional view of the battery storage portion. Although the detailed description is omitted because it is basically the same as that of the first embodiment, in the case of a battery having positive and negative electrodes at one end, for example, the 006P type, the portion corresponding to the electrode of the battery and the connecting portion 6 serving as the supply terminal to the device is In general, the connector terminal 10 is not provided and the elastic force is not applied. However, when the battery 5 is pressed down, the fulcrum 4
The battery 5 can be easily taken out by simply rotating the seesaw around the center and lifting the battery.

[0010]

EFFECTS OF THE INVENTION By providing a recess for accommodating a part of a battery in the bottom of the battery accommodating portion, by pressing the end on the recessed side of the battery, the opposite side of the battery pressed around the fulcrum Since the end of the battery floats up and the battery can be easily picked up without auxiliary tools, battery replacement becomes easy. Further, even if the device progresses toward miniaturization, the position of the fulcrum determined by the position of the recess may be changed by design, which will be useful for effective use of the space of the battery storage portion.
