FIG. 8 is a perspective view showing an external shape of the battery housing structure shown in FIG. 6 with each component attached, and FIG. 8 is a plan view of the battery housing structure shown in FIG.

  First, referring to FIG. 6, the battery housing structure 1 is configured by connecting the battery box 2 and the battery box 42 on one side (front-rear direction) of the battery box body 3 on the long side in plan view. Specifically, the first engaged portion 17 in front of the battery box 2 and the second engaged portion 50 in the rear of the battery box 42 are engaged, and the first engaged portion in the front of the battery box 2 is engaged. The second connection state of the battery housing structure 1 is configured by engaging the portion 18 and the second engagement portion 49 behind the battery box 42.

  Further, the battery housing structure 1 simultaneously inserts its leg portions 66a and 66b into the terminal receiving and receiving portion 25a of the battery box 2 and the terminal receiving and receiving portion 55a of the battery box 42 adjacent thereto on the left side. A connection terminal receiver 63a to be attached is further provided.

  The connection terminal receptacle 63a has a terminal receptacle introduction port 65a to which the terminal receptacle 24a around which the conducting wire 33a is wound can be attached as shown by the two-dot chain line arrow in FIG. Further, terminals are provided on the leg portions 66a and 66b and the terminal receiving / introducing port 65a of the connecting terminal receiving 63a, and the leg portions 66a and 66b and the terminal receiving / introducing port 65a are electrically connected.

  Similarly, the connecting terminal receiver 63b having the same shape as the connecting terminal receiver 63a similarly has a terminal receiving introduction port 65b and leg portions 66c and 66d, and on the right side, the terminal receiving / receiving portion 25b and the terminal receiving / receiving terminal adjacent thereto. It is attached to the part 55b at the same time.

  6, the batteries 31 and 51 are stored in the battery boxes 2 and 42 of the battery storage structure 1, and the connection terminal receiver 63a is connected to the terminal receiver storage section 25a and the terminal receiver storage section 55a. As a result, the surfaces of the leg portions 66a and 66b are in contact with the positive terminal 36 of the battery 31 and the positive terminal 56 of the battery 51, and can be energized through the terminal receiver 24a.

  Similarly, the connecting terminal receiver 63b can be energized by contacting the negative terminal 37 of the battery 31 and the negative terminal 57 of the battery 51 adjacent thereto.

  As described above, in the second connection state, the batteries 31, 51 are energized by attaching the connecting terminal receivers 63a, 63b, so that it is not necessary to connect the batteries 31, 51 with the conductive wires, and the convenience and reliability are improved. .

  And the battery storage structure 1 shown in FIG.7 and FIG.8 is comprised by attaching each component in this way. In these drawings, depiction of the conducting wire is omitted.

  7 and 8 in conjunction with FIG. 6, the battery 31 housed in the battery box 2 and the battery 51 housed in the battery box 42 are in the same direction (the positive terminal 36 of the battery 31 and the positive electrode of the battery 51). Both of the terminals 56 face left), and the positive terminal 36 of the battery 31 and the positive terminal 56 of the battery 51 are connected by a connecting terminal receiver 63a, and the negative terminal 37 of the battery 31 and the negative terminal 57 of the battery 51 are connected. Is connected by the connecting terminal receiver 63b, and thus in the second connection state shown in FIGS. 7 and 8, a parallel connection is formed.

  Next, FIG. 9 is a plan view showing the movement of the battery box when the battery housing structure is switched from the first connection state to the second connection state.

  Referring to the figure, when switching the battery housing structure 1 from the first connection state described above with reference to FIG. 5 to the second connection state described above with reference to FIG. For example, the battery box 42 is moved to a position in the second connection state (position where the battery box body 3 is connected on the long side), and then the battery box 2 and the battery box 42 are connected. It connects by engaging a predetermined engaging part and a to-be-engaged part.

  That is, as a first switching method, the engagement between the first engaging portion 17 of the battery box 2 and the first engaged portion 48 of the battery box 42 is released, and the second engaged portion of the battery box 2 is released. 20 and the battery box 42 are switched to the second connected state by rotating the battery box 42 as indicated by the one-dot chain arrow in the upper part of FIG. Can do.

  In the first switching method, as described above, the engaging portion and the engaged portion are the shaft body and the bearing that engages with the shaft body. Therefore, the degree of freedom of connection arrangement is further improved.

  In this state, since the battery 31 of the battery box 2 and the battery 51 of the battery box 42 face different directions, when the terminals adjacent to each other of the battery 31 and the battery 51 are connected by a terminal receiver or a connecting terminal receiver. It becomes a series connection or a short circuit. When parallel connection is desired, the battery 31 or the battery 51 may be removed from the battery box 2 or the battery box 42 and the directions may be switched.

  In addition, the battery box 42 can be rotated and moved as indicated by the one-dot chain line arrow in the lower part of FIG. 9, and similarly switched to the second connection state.

  Further, as a second switching method, after the battery box 2 and the battery box 42 are completely disengaged, the battery box 42 is connected to the battery box 2 as indicated by a two-dot chain line in the upper part or the lower part of FIG. It can switch to the parallel connection of a 2nd connection state by moving to the front side or back side.

  As described above, the battery box 42 can be connected to any of the front, rear, left and right sides of the battery box 2 except for the case where the front and back sides are reversed (the state where the bottom portion is vertically upward). The degree of freedom is high.

  As described above, the battery housing structure of the present invention includes a first connection state in which one battery box 2 and another battery box 42 are coupled on the short side in plan view of the battery box body 3, and a flat surface. Since the second connection state connected on the viewing long side can be switched freely, one battery box 2 and the other battery box 42 are connected to the short side and the long side in the plan view of the battery box body 3. In any case, it is possible to easily connect, the degree of freedom of connection arrangement is improved, and it becomes compact.

  Further, the battery box of the present invention is compact because the battery boxes 2 and 42 having the same shape can be connected to each other by engaging the engaging portions and the engaged portions of the corresponding sides. At the same time, the connection state is stabilized.

  Such a battery storage structure and battery box can be designed by the user himself / herself due to the high degree of freedom of the connection arrangement, and ensure safety by using a manganese battery. Since it is possible to configure a short circuit as a premise, it is preferably used as a learning material. In addition, when the connection terminal receiver is used in the second connection state, it can be seen that the connection terminal receivers are connected in a U-shape without using a lead wire between adjacent battery terminals. This makes it easier to understand and is more suitable as a learning material.

  Next, FIG. 10 is a schematic diagram showing a first connection state and a second connection state of the battery housing structure according to the second embodiment of the present invention.

  Referring to the drawing, a battery housing structure 71 is formed by connecting a battery box 72 drawn with a solid line and a battery box 82 drawn with an alternate long and short dash line in FIG.

The same. Therefore, it demonstrates below centering on a difference.

  In the plan view schematically shown in the figure, the outer edge of the battery box body 73 is a rectangle and the center point thereof is a point 75, and the center of a virtual rectangle 74 that connects the engaging portion and the engaged portion with a virtual straight line. The point is a point 76, and the rectangle of the outer edge of the battery box body 73 is not matched because it is biased forward inside the virtual rectangle 74. Therefore, for example, when the battery box 82 shown on the right side of the figure is connected to the battery box 72 on the short side in a state where the battery box 82 is rotated 180 degrees in the front-rear direction from the direction shown in the figure, the first connection state can be configured. However, the positions of the battery box bodies are not aligned in the front-rear direction. Also in this case, since the terminals of the batteries accommodated in the battery boxes 72 and 82 are connected by a conducting wire, they can be used. However, as in the first embodiment of the present invention described above, if the center point of the outer edge of the battery box body coincides with the center point of the virtual rectangle in plan view, the first connection state and the first When the battery boxes are connected in any direction in the connected state 2, the positions of the battery box bodies are aligned in the front-rear direction or the left-right direction, which is preferable because the degree of freedom of the connection arrangement is further improved.

  In each of the above embodiments, a specific detachable terminal receiver is used, but a terminal receiver formed integrally with the battery box may be used. Moreover, you may use the metal terminal receptacle which has electroconductivity. Alternatively, the battery may be directly energized with a conductive wire without using a terminal receptacle.

  Further, in each of the above embodiments, the terminal terminal is attached to the connection terminal receiver for energization. However, the conductor may be energized by, for example, winding a conducting wire around the connection terminal receiver without attaching the terminal receiver.

  Furthermore, in each of the above embodiments, the connection terminal receiver is provided, but the connection terminal receiver may not be provided.

  Further, in each of the above-described embodiments, the connection terminal receivers are attached to both the positive electrode side and the negative electrode side of the battery in the second connection state, but the connection terminal receivers are attached only to one side and the terminals are connected to the other side. You may attach a receptacle to each of the terminal of an adjacent battery. In particular, when a series connection is used in the second connection state, this is used.

  Furthermore, in each of the above embodiments, the engaging portion and the engaged portion have a specific positional relationship, but the positional relationship may be interchanged.

  Further, in each of the above-described embodiments, the engaging portion and the engaged portion have a specific shape (shaft body and bearing), but may have other shapes. For example, a bowl-shaped body and a ring body that engages with it, a convex body and a concave body that engages with this, and the like. However, from the viewpoint of the degree of freedom of rotational movement and connection arrangement, the above-described shaft body and bearing are preferable.

  Furthermore, in each of the above embodiments, the outer edge of the battery box body in plan view has a substantially rectangular shape, but other shapes are substantially included in the substantially rectangular shape without departing from the gist of the present invention. . For example, a semi-cylindrical shape, a shape in which each corner portion is rounded, a shape that is tapered or inversely tapered in the vertical direction, a shape in which corrugations or irregularities are formed on the outer edge, etc. Can be mentioned.

  Furthermore, in each of the above-described embodiments, a virtual rectangle is formed by connecting a pair of engaging portions and a pair of engaged portions with a virtual straight line. However, at least a quadrangular virtual rectangle may be used. Even in this case, since the battery boxes having the same shape can be connected by engaging the engaging portions and the engaged portions of the corresponding sides, it is compact and the corresponding sides are connected. As a result, the connection state is stabilized.
