In this embodiment, the sum of the length of the battery lid partition portion 624 and the length of the upper partition portion 6113 is formed to be slightly shorter than the length of the cylindrical battery B.

The auxiliary partition portion 624a has a shape that draws an arc along the outer shape of the portion of the two cylindrical batteries B housed in the upper stage 611 of the battery storage recess 61 near the upper front / rear connection space 6114.

<Electrical connection>
FIG. 9 simply shows the electrical connection of the four positive electrode terminals (6111a, 6112a, 6122a, 6123a) and the four negative electrode terminals (6111c, 6112c, 6122c, 6123c) provided in the battery storage recess 61. .. The four positive electrode terminals and the four negative electrode terminals are electrically connected so that the four cylindrical batteries B housed in the battery storage recess 61 are connected in series.

<Action effect>
As shown in FIGS. 3 and 4, in order to store the cylindrical battery B in the battery storage structure 6, the user first starts from a state in which the grip portion 41 of the charging handle 4 is stored in the grip portion storage groove 44. , Pull up the charging handle 4.

When the handle 42 of the charging handle 4 comes off from the battery lid 62, the user can push the battery lid plate spring hooking protrusion 623 to the right with the finger F. By this operation, the shoulder portion 623a is not locked to the leaf spring hooking recess 6115a, and the battery lid 62 can be pulled up. Further, when the right end hooking protrusion 622 of the battery lid is removed from the right end hooking recess 6115b, the battery lid 62 is completely removed from the opening 6115 (FIG. 5).

As shown in FIG. 10, the cylindrical battery B is housed in the lower 612. The cylindrical battery B is inserted into the lower front battery storage space 6122b so that the negative electrode B2 of the cylindrical battery B is inserted toward the lower front negative electrode terminal 6122c. Then, when the positive electrode B1 side of the cylindrical battery B is pushed in the lower right direction with the finger F, the cylindrical battery B is correctly fitted in the lower front battery storage space 6122b, and the positive electrode B1 of the cylindrical battery B is the lower front positive electrode end. The negative electrode B2 contacts the child 6122a with the lower front negative electrode terminal 6122c.

The cylindrical battery B is also stored in the lower rear battery storage unit 6123 in the same manner.

The cylindrical battery B is stored in the upper 611. While pushing the negative electrode B2 of the cylindrical battery B toward the upper front negative electrode terminal 6111c, the cylindrical battery B is inserted into the upper front battery storage space 6111b.

Then, when the positive electrode B1 of the cylindrical battery B is pushed in the lower right direction with the finger F, the cylindrical battery B is correctly fitted in the battery storage space. Then, the positive electrode B1 of the cylindrical battery B contacts the upper front positive electrode terminal portion 6111a, and the negative electrode B2 contacts the upper front negative electrode terminal 6111c.

At this time, since the cylindrical battery B is housed in the lower tier 612, the bottom surface side of the cylindrical battery B housed in the upper tier 611 is supported by the upper surface of the step 6121 and the upper side of the cylindrical battery B in the lower tier 612 and is stable. ing.

Similarly, the cylindrical battery B is stored in the upper rear battery storage space 6112b.

As shown in FIG. 12, when the four cylindrical batteries B are stored in the battery storage recess 61, the two cylindrical batteries B housed in the upper 611 with the battery lid 62 not attached to the opening 6115. The left end side is stored in the battery storage recess 61 without a gap by the upper partition portion 6113.

On the other hand, on the right end side, a gap of upper front / rear connection space 6114 is created between the two cylindrical batteries B, which causes the cylindrical battery B to rattle.

Therefore, as shown in FIG. 4, when the battery lid 62 is attached to the opening 6115, the two cylindrical batteries B in which the battery lid partition portion 624 and the auxiliary partition portion 624a on the back side of the battery lid 62 are housed in the upper stage 611. It enters the upper front / rear connection space 6114 in between.

Then, the battery lid partition portion 624 and the auxiliary partition portion 624a fill the upper front / rear connection space 6114 to prevent the two cylindrical batteries B housed in the upper stage 611 from rattling.

Finally, as shown in FIG. 3, the charging handle 4 is folded so that the grip portion 41 of the charging handle 4 is housed in the grip portion storage groove 44.

In this way, four cylindrical batteries B are stored in the battery storage recess 61, and all the cylindrical batteries B are electrically connected in series. Then, electric power can be supplied from the four cylindrical batteries B to the light source unit 2, the functional unit 3 such as a radio, and the like.

When removing the four cylindrical batteries B, the handle is pulled up, the battery lid 62 is removed from the opening 6115, and then the cylindrical battery B in the upper stage 611 is removed.

To remove the two cylindrical batteries B in the upper 611, the user pulls up the positive electrode B1 side of the cylindrical battery B while pushing it to the right with a fingernail N or the like. In this way, the two cylindrical batteries B are removed from the upper front battery storage space 6111b and the upper rear battery storage space 6112b.

As shown in FIG. 11, the cylindrical battery B in the lower 612 is then removed. To remove it, the user pulls up the positive electrode B1 of the cylindrical battery B while pushing it to the right with a fingernail N or the like.

At this time, as shown in FIG. 11, the upper partition portion 6113 is located only in the vicinity of the step 6121 and does not extend to the right end. Therefore, the upper partition portion 6113 does not get in the way when the user inserts the finger F. Further, the upper partition portion 6113 does not get in the way when visually recognizing the gap between the positive electrode B1 of the cylindrical battery B into which the claw N of the fingertip F or the like is to be inserted and the positive electrode terminal of the lower 612.

Further, when the finger F connected to the claw N is tilted toward the cylindrical battery B side or at an angle close to vertical when the positive electrode B1 side of the cylindrical battery B is pushed by the claw N, the cylindrical battery B is formed by the claw N. When pushing to the right, a force is applied to the nail N in the direction in which the finger N is peeled off from the finger F. Therefore, the user may have a pain at the base of the claw N, or may not be able to apply sufficient force to the cylindrical battery B to remove the cylindrical battery B.

In order to avoid this problem, the positive electrode B1 of the cylindrical battery B must be pushed to the right by the claw N while tilting the finger F toward the step 6121. By doing so, no force is applied to the nail N in the direction in which the nail N is peeled off from the finger F.

As shown in FIG. 13, since a space is created on the upper left side of the positive electrode B1 of the cylindrical battery B housed in the lower stage 612 by the step 6121, the user can tilt the finger F to the step 6121 side and claw N or the like. Can push the positive electrode B1 side of the cylindrical battery B with.

In this way, all four cylindrical batteries B, including the two cylindrical batteries B in the lower 612, can be removed from the battery storage recess 61.

Further, even if the cylindrical battery B is moved to an incorrect position in the battery storage recess 61 for some reason, the battery storage structure 6 according to the present embodiment does not cause a short circuit.

Since there is a sufficient distance between the positive electrode terminal of the upper stage 611 and the negative electrode terminal of the lower stage 612 due to the provision of the step 6121, one electrode of the cylindrical battery B is cylindrical while being in contact with the positive electrode terminal of the upper stage 611. The other electrode of the battery B is not connected to the negative electrode terminal of the lower 612 and short-circuited.

Since the distance between the positive electrode terminal of the lower 612 and the negative electrode terminal of the upper 611 is shorter than the length of the cylindrical battery B, the positive electrode B1 and the negative electrode B2 of the cylindrical battery B are connected to these terminals, respectively. There is no short circuit.

The cylindrical battery B is positioned diagonally in the front-rear direction D2 in the upper 611, and the positive electrode B1 and the negative electrode B2 of the cylindrical battery B are attached to the upper front positive electrode terminal portion 6111a and the upper rear negative electrode terminal 6112c. There is no connection between them.

This is because the upper partition portion 6113 regulates the position of the cylindrical battery B so that the cylindrical battery B cannot move to such a position. Similarly, the positive electrode B1 and the negative electrode B2 of the cylindrical battery B are not connected to the upper rear positive electrode terminal 6112a and the upper front negative electrode terminal 6111c, respectively.

Similar to the inside of the upper stage 611, the cylindrical battery B is positioned diagonally in the front-rear direction D2 in the lower stage 612, and there is no short circuit. This is because the lower partition portion 6124 regulates the position of the cylindrical battery B.

By the way, as shown in FIG. 16, in the conventional battery storage structure 6 having no step 6121, even if the cylindrical battery B stored in the lower 612 is to be removed by the fingernail N of the finger F, the upper left portion of the cylindrical battery B There is no space in. Therefore, it is necessary to provide a ribbon or the like for removing the cylindrical battery B in the lower tier 612.

On the other hand, as described above, in the battery storage structure 6 according to the present embodiment, all the cylindrical batteries B can be stored and removed only by the finger F. Therefore, it is not necessary to provide a ribbon or the like for removing the cylindrical battery B in the lower tier 612.

Since it is not necessary to provide a ribbon or the like, the ribbon or the like is entangled with the cylindrical battery B and short-circuited, and when the cylindrical battery B is removed using the ribbon or the like, the cylindrical battery B moves to an unexpected position. It is possible to avoid the trouble of storing the cylindrical battery B while paying attention to the position of the ribbon or the like, in which a short circuit occurs or the cylindrical battery B pops out vigorously.

Further, when four cylindrical batteries B are stored in the battery storage recess 61, the battery lid 62 is attached to the opening 6115, and the handle is folded, as shown in FIG. 3, the handle of the charging handle 4 is on the outside of the battery lid 62. 42 will be located. Therefore, even when something hits the periphery of the battery storage structure 6 such as when the main body falls, the object first hits the handle 42 portion of the charging handle 4. In this way, the impact applied to the battery storage structure 6 is reduced.

<Second embodiment>
Next, the battery storage structure 6 according to the second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals as those in the first embodiment, and detailed description thereof will be omitted.

The lower 612 of the second embodiment does not have the lower rear battery storage portion 6123 and the lower partition portion 6124, and the lower tier 612 can store only one cylindrical battery B. Different from the embodiment.

Even the battery storage structure 6 according to the second embodiment has the same function and effect as the battery storage structure 6 according to the first embodiment.

That is, the position of the cylindrical battery B is restricted by the step 6121 and the upper partition portion 6113, and the cylindrical battery B does not move to an incorrect position and cause a short circuit.

Further, the step 6121 creates a space on the upper left side of the cylindrical battery B housed in the lower tier 612, and the user can remove the cylindrical battery B in the lower tier 612 with the finger F without providing a ribbon or the like.

The upper partition 6113 interferes with the removal of the cylindrical battery B of the lower 612 by the upper front / rear connection space 6114 provided at the upper part of the step 6121 and the battery lid partition 624 provided on the back side of the battery lid 62. It has both the fact that it does not become a problem and the prevention of rattling of the cylindrical battery B in the upper stage 611.

<Third embodiment>
Next, the battery storage structure 6 according to the third embodiment of the present invention will be described with reference to FIG. In the third embodiment, the same components as those in the first embodiment are designated by the same reference numerals as those in the first embodiment, and detailed description thereof will be omitted.

The third embodiment differs from the first embodiment in the following points. The upper partition portion 6113 in the first embodiment is not provided, and instead, the step upper front / rear connection space 6116 is provided. Further, the lower partition portion 6124 in the first embodiment extends upward to the vicinity of the upper surface of the upper partition 611 to form the upper and lower partition portions 6117.

The position of the battery lid partition portion 624 on the back side of the battery lid 62 is changed to a position where the battery lid 62 enters the step upper front / rear connection space 6116 when the battery lid 62 is attached to the opening 6115, that is, the left end side. The length of the battery lid partition portion 624 in the left-right direction is also shortened in accordance with the length of the left-right direction D3 of the step upper front / rear connection space 6116.

Even the battery storage structure 6 according to the third embodiment has the same function and effect as the battery storage structure 6 according to the first embodiment.

That is, the position of the cylindrical battery B is restricted by the step 6121 and the upper and lower partition portions 6117, and the cylindrical battery B does not move to an incorrect position and cause a short circuit.

Further, the step 6121 creates a space on the upper left side of the positive electrode B1 of the cylindrical battery B housed in the lower tier 612, and the user can remove the cylindrical battery B in the lower tier 612 with the finger F without providing a ribbon or the like. Can be done.

The upper front / rear connection space 6116 of the step and the battery lid partition 624 provided on the back side of the battery lid 62 prevent the upper and lower partition 6117 from getting in the way when the cylindrical battery B of the lower 612 is removed, and the upper partition 611. Both prevent rattling of the cylindrical battery B of the above.
