Further, the X1-X2 direction indicates the width direction of the spacer 1 and also indicates the moving direction of the outer wall surface members 11, 11 at the time of expansion and contraction. Furthermore, the Z1-Z2 direction indicates the height direction of the spacer 1.

The outer wall surface member 11 is a member that directly abuts against a member to be pressed in the spacer 1, and is configured by a thin plate member having a substantially rectangular shape. The pair of outer wall surface members 11, 11 have the same structure. The pair of outer wall surface members 11, 11 are arranged so as to extend in parallel along the Y1-Y2 direction. The length of the outer wall surface member 11 along the Y1-Y2 direction and the height along the Z1-Z2 direction are not limited to the illustrated length and height, and the size of the portion to which the spacer 1 is applied and the member to be held. It is appropriately set according to the size of the surface of the.

The slide member 12 is a member for moving the outer wall surface member 11 relative to the outer wall surface member 11 in the Y1-Y2 direction to operate the expansion and contraction operations, and has the substantially same length and height as the outer wall surface member 11. It is configured by a rectangular plate member having a height. The thickness of the slide member 12 along the X1-X2 direction is larger than the thickness of the outer wall surface member 11, and has rigidity necessary for the moving operation at the time of expansion and contraction. The slide member 12 is arranged between the pair of outer wall surface members 11, 11 along the Y1-Y2 direction so as to extend parallel to the outer wall surface members 11, 11.

The slide member 12 has a rectangular push surface portion 121 at one end portion 12a (end portion in the Y2 direction). The height of the pressing surface portion 121 is substantially equal to the height of the slide member 12. Further, the width of the pressing surface portion 121 along the X1-X2 direction is larger than the width (thickness) of the slide member 12. The one end portion 12a of the slide member 12 has a T-shape in a plan view because the pressing surface portion 121 is provided.

The movable connecting member 13 is formed of a rectangular small piece plate-shaped member, is arranged between the outer wall surface member 11 and the slide member 12, and connects the outer wall surface member 11 and the slide member 12. In the present embodiment, the pair of movable connecting members 13 and 13 are arranged so as to face each other with the slide member 12 sandwiched therebetween, and the pair of movable connecting members 13 and 13 is arranged in the longitudinal direction of the slide member 12 ( They are arranged at equal intervals along the (Y1-Y2 direction). The height of the movable connection member 13 is substantially the same as the height of the outer wall surface member 11 and the slide member 12. Further, in the state where the movable connecting member 13 is arranged substantially at right angles to the outer wall surface member 11 and the slide member 12 (the state shown in FIG. 2), the pair of movable connecting members 13 arranged with the slide member 12 interposed therebetween, The width of the entire 13 in the X1-X2 direction is substantially equal to the width of the pressing surface portion 121 in the X1-X2 direction. The number of movable connection members 13 provided is not particularly limited, and is appropriately set according to the pressing load required for the spacer 1, the length of the spacer 1, and the like.

The connection structure of the movable connecting member 13 will be further described with reference to FIG. FIG. 5 is an enlarged plan view showing a connection structure of the slide member, the outer wall surface member and the movable connection member in the spacer of the first embodiment.
As shown in FIG. 5, the movable connection member 13 has an outer surface 13a that faces the inner surface (a surface facing the slide member 12) 11c of the outer wall member 11, and an outer surface of the slide member 12 (which faces the outer wall member 11). Inner surface 13b facing the surface 12c.

One side of the outer side surface 13a of the movable connecting member 13 and the inner side 11c of the outer wall surface member 11 are connected by the connecting portion 131 so as to be swingable along the Y1-Y2 direction, and one side of the inner side surface 13b of the movable connecting member 13 is connected. The outer surface 12c of the slide member 12 is swingably connected to the outer surface 12c of the slide member 12 along the Y1-Y2 direction by the connecting portion 132. These connecting portions 131 and 132 are formed in the height direction of the movable connecting member 13.

Here, the outer wall surface member 11, the slide member 12, and the movable connecting member 13 in the spacer 1 of the present embodiment are all integrally formed of resin such as PP (polypropylene). The connecting portions 131 and 132 are formed by partially thinning the resin. When the spacer 1 is required to have higher strength, the outer wall surface member 11, the slide member 12, and the movable connecting member 13 can be formed of a metal material. In that case, by coating the surface of the metal material with a resin, the connection portions 131 and 132 made of a thin resin can be formed. Further, the connecting portions 131 and 132 are not limited to those made of a thin resin, and although not shown, between the outer wall surface member 11 and the movable connecting member 13 and between the slide member 12 and the movable connecting member 13. May be connected so as to be swingable by pivots.

As shown in FIG. 2, when the movable connecting member 13 is observed in a state where the movable connecting member 13 is arranged substantially at right angles to the outer wall surface member 11 and the slide member 12, the connecting portion 131 is The outer side surface 13a is disposed on the most Y2 direction side (the side on which the pushing surface portion 121 is disposed) of the edge portion, and the connecting portion 132 is disposed on the inner side surface 13b of the movable connecting member 13 on the most Y1 direction side edge portion. .. Therefore, as shown in FIG. 5, the movable connection member 13 can be swung in the α1-α2 direction with respect to the outer wall surface member 11 around the connection portion 131, and can be connected to the slide member 12 with respect to the connection portion. It can be swung in the β1-β2 direction about 132.

In this way, the movable connection member 13 connects the outer wall surface member 11 and the slide member 12 so as to be swingable, so that the outer wall surface member 11 and the slide member 12 relatively face each other along the Y1-Y2 direction. It can be reciprocally moved. When the outer wall surface member 11 and the slide member 12 move relative to each other, each movable connection member 13 swings with respect to the outer wall surface member 11 and the slide member 12 about the connecting portions 131 and 132, respectively, The outer wall surface members 11, 11 are moved in parallel with respect to the slide member 12 along the X1-X2 direction. As a result, the outer wall surface member 11 can be moved toward or away from the slide member 12.

The spacer 1 shown in FIGS. 1 and 2 shows a state in which the pair of outer wall surface members 11, 11 are moved farthest from the slide member 12 to deploy the outer wall surface members 11, 11 (hereinafter referred to as a deployed state). ing. In the unfolded state, the slide member 12 moves most in the Y1 direction with respect to the outer wall surface member 11. At this time, as shown in FIG. 5, each movable connecting member 13 swings in the α1 direction around the connecting portion 131 and swings in the β1 direction around the connecting portion 132, so that The wall member 11 and the slide member 12 are erected at a substantially right angle.

The positions of the pair of outer wall surface members 11, 11 and the slide member 12 in the unfolded state are aligned in the Y1-Y2 direction. Specifically, the positions of the one end portions 11a and 11a (end portions in the Y2 direction) of the pair of outer wall surface members 11 and 11 and the one end portion 12a of the slide member 12 are set to the same position, and The positions of the other ends 11b, 11b (ends in the Y1 direction) of the pair of outer wall members 11, 11 and the position of the other end 12b (ends in the Y1 direction) of the slide member 12 are the same. .. At this time, the pressing surface portion 121 is sandwiched between the one end portions 11a, 11a of the pair of outer wall surface members 11, 11 and is flush with the one end portions 11a, 11a. Therefore, by visually confirming this flush state, it is possible to confirm that the spacer 1 has been completely developed.

On the other hand, the spacer 1 shown in FIGS. 3 and 4 is in a state where the pair of outer wall surface members 11, 11 are closest to the slide member 12 and the outer wall surface members 11, 11 are contracted (hereinafter referred to as a contracted state). Shows. In this contracted state, the slide member 12 moves most in the Y2 direction with respect to the outer wall surface member 11. At this time, as shown in FIG. 5, each movable connecting member 13 swings in the α2 direction about the connecting portion 131 and swings in the β2 direction about the connecting portion 132, thereby The wall member 11 and the slide member 12 are laid down substantially parallel to each other. Further, the position of the one end 12a of the slide member 12 in the contracted state is a position projecting in the Y2 direction from the one end 11a of the outer wall member 11, and the position of the other end 12b of the slide member 12 is the outside. The wall member 11 is at a position retracted from the other end 11b in the Y2 direction.

Next, a method of using the spacer 1 will be described.
As shown in FIGS. 3 and 4, the spacer 1 is in a contracted state in which the outer wall surface member 11 is moved closest to the slide member 12. At this time, the one end portion 12a of the slide member 12 and the pressing surface portion 121 project in the Y2 direction from the one end portions 11a, 11a of the pair of outer wall surface members 11, 11, and the other end portion 12b of the slide member 12 has a pair of ends. The outer wall surface members 11, 11 are further retracted in the Y2 direction than the other ends 11b, 11b.

First, as shown in FIG. 4, the spacer 1 in the reduced state is placed between the two holding target members E, E, which are spaced apart from each other, and the other one of the outer wall surface member 11 and the slide member 12 is provided. Inserting is performed along the Y1 direction from the end portions 11b and 12b (first step). Between the two holding target members E, E, the holding target surfaces E1, E1 of the holding target members E, E are parallel to each other. The outer wall surface members 11, 11 of the spacer 1 are arranged along the holding target surfaces E1, E1.

By inserting the spacer 1 further into the depth, as shown in FIG. 4, the other end 11b of the outer wall surface member 11 arranged on the leading side in the insertion direction (Y1 direction) is arranged at the end of the insertion direction. The abutting surface E2 is brought into contact (second step).

Next, the slide member 12 is pushed in the Y1 direction by using the pressing surface portion 121 to move the slide member 12 relative to the outer wall surface member 11 in the Y1 direction. Since the pressing surface portion 121 is formed wider than the slide member 12, the slide member 12 can be easily pushed in and operated.

When each movable connection member 13 swings due to the movement of the slide member 12, the pair of outer wall surface members 11, 11 are moved away from the slide member 12 and expanded as shown in FIGS. 1 and 2. As a result, the outer wall surface members 11, 11 come into contact with the holding target surfaces E1, E1, respectively, and apply a pressing load to these holding target surfaces E1, E1 (third step). At this time, the push surface portion 121 of the slide member 12 is sandwiched between the one end portions 11a and 11a of the outer wall surface members 11 and 11 to be flush with each other. The holding target members E and E to which the holding target surface E1 is pressed are held between these members or surfaces and the spacer 1 by abutting against other members or other surfaces (not shown) arranged in the pressing direction. To be done.

Here, as shown in FIG. 2, the developed width W1 of the spacer 1 along the X1-X2 direction in the expanded state is slightly larger than the distance W2 between the two holding target surfaces E1 and E1. , W1>W2. This is usually achieved by appropriately setting the widths of the movable connecting member 13 and the pressing surface portion 121. As a result, the pair of outer wall surface members 11 and 11 in the expanded state abut on the two holding target surfaces E1 and E1, and further, as indicated by arrows in FIG. 2, between the holding target surfaces E1 and E1. An appropriate pressing load can be applied in the direction of increasing the distance.

Further, since the movable connection members 13 are arranged at equal intervals along the moving direction of the slide member 12 (Y1-Y2 direction), the outer wall surface member 11 applies a uniform pressing load to the holding target surface E1. It is possible to Moreover, in the expanded state, the pair of movable connection members 13 and 13 are arranged so as to sandwich the slide member 12 and support the pair of outer wall surface members 11 and 11. Therefore, the pressing state against the holding target surfaces E1 and E1 is also possible. Stabilize.

When removing the spacer 1 by releasing the pressing, the slide member 12 of the spacer 1 in the expanded state is pulled out to the front side by using the pressing surface portion 121, so that the direction opposite to the insertion direction (Y2 Direction). Due to the movement of the slide member 12, each movable connection member 13 swings in the direction opposite to the direction at the time of deployment, and the pair of outer wall surface members 11, 11 are moved closer to the slide member 12 to move the slide member 12 to the positions shown in FIGS. Reduce as shown in. As a result, the outer wall surface members 11 and 11 are separated from the holding target surfaces E1 and E1, respectively, and the pressing against the holding target surfaces E1 and E1 is released (fourth step). After that, the spacer 1 is taken out from between the two holding target members E, E.

As described above, according to the spacer 1, the pressing load is applied to the holding target surface E1 of the holding target member E only by moving the slide member 12 in the pushing direction to deploy the pair of outer wall surface members 11, 11. Therefore, the holding target member E can be held quickly and easily. Moreover, when the spacer 1 is inserted or removed between the two holding target members E, E, since the spacer 1 is in the contracted state, the spacer 1 can be easily inserted and removed even in a narrow space. Since the spacer 1 after being removed is in a reduced state, it can be compactly stored when not in use. Moreover, the spacer 1 can be repeatedly used. Further, the outer wall surface member 11 only moves in the direction toward or away from the slide member 12 due to the swing of the movable connecting member 13, and hardly moves in the surface direction with respect to the holding target surfaces E1 and E1. Therefore, the holding target surface E1 and the outer wall surface member 11 are not rubbed, and the holding target surface E1 is not rubbed and damaged.

As shown in FIGS. 2 and 4, the outer wall member 11 may have a curved portion 111 that curves along the moving direction of the slide member 12 so as to be convex outward. The curved portion 111 is arranged correspondingly between the movable connection members 13, 13 that are adjacent to each other along the moving direction (Y1-Y2 direction) of the slide member 12. Since the outer wall surface member 11 has a thin plate shape, when a pressing load is applied to the holding target surface E1, the curved portion 111 elastically deforms and exhibits elasticity, so that the holding target surface E1 is held. Appropriate pressing load can be applied. In addition, the bending portion 111 can absorb the tolerance of the separation distance W2 between the two holding target surfaces E1 and E1 by appropriately bending and deforming. The elasticity of the bending portion 111 and the degree of absorption of the tolerance can be adjusted by appropriately setting the curvature of the bending portion 111, the thickness of the bending portion 111, and the like.

FIG. 6 is an enlarged plan view showing a developed state of the spacer according to the present invention.
As shown in FIG. 6, in the spacer 1 of the present embodiment, the movable connecting member 13 in the expanded state is swung in the α1 direction and the β1 direction around the connecting portions 131 and 132 to be in the standing state. The movable connection member 13 is configured to further swing beyond the state of standing upright with respect to the outer wall surface member 11 and the slide member 12. This is because the movable connecting member 13 slightly inclines toward the edge portion side where the connecting portions 131 and 132 are not arranged on the outer side surface 13a and the inner side surface 13b. As a result, the movable connecting member 13 that has swung to the expanded state is in a standing state beyond the so-called overcenter state. As a result, even if a load is applied to the outer wall members 11, 11 in the deployed state in the contracting direction (approaching direction to the slide member 12), the movable connecting member 13 is less likely to swing in the fall direction, and the deployed state is It exerts a lock effect to maintain.

As a method of setting the movable connecting member 13 in the overcenter state, the inner surface 11c of the outer wall surface member 11 and the outer surface 12c of the slide member 12 are provided with the outer surface 13a and the inner surface 13b of the movable connecting member 13. A housing groove (not shown) that can be housed may be provided so as to be tilted so as to be in an over-center state.

The movable connecting member 13 is not limited to the one that is slightly inclined in the overcenter state as described above, and although not shown, the outer side surface 13a and the inner side surface 13b of the movable connecting member 13 are the outer wall surface member. It may be configured to abut on the sliding member 11 and the sliding member 12 with a completely flat surface. That is, as shown in FIG. 5, the outer wall surface members 11 and 11 have the maximum expansion width at the moment when the diagonal line 133 connecting the connecting portion 131 and the connecting portion 132 of the movable connecting member 13 is perpendicular to the slide member 12. Then, when the slide member 12 further slides to proceed with the expansion, the movable connecting member 13 is brought into the over-center state, and as shown in FIG. 6, the angle formed by the diagonal line 133 of the movable connecting member 13 and the slide member 12 is made. θ becomes an acute angle. In this state, even if the outer side surface 13a and the inner side surface 13b of the movable connection member 13 are in contact with the outer wall surface member 11 and the slide member 12 with completely flat surfaces, When a load is applied to the movable connection member 13, a force in a direction (Y1 direction) for further advancing the deployed state is applied to the slide member 12, and a locking effect for maintaining the deployed state is exerted similarly to the above. You can

As a means for locking the spacer 1 in the deployed state, a separate locking mechanism may be provided in addition to the overcenter state of the movable connecting member 13 as described above. FIG. 7 is a plan view showing an example of the lock mechanism. The spacer 1 shown in FIG. 7 is in a developed state.
The lock mechanism 14 according to the present embodiment is configured between the one end portion 11 a of the outer wall surface member 11 and the pressing surface portion 121. A convex portion 112 is provided on the inner surface 11c side of the one end portion 11a of the outer wall surface member 11. On the other hand, a concave portion 122 having a shape corresponding to the convex portion 112 is provided on the end surface 121a of the pressing surface portion 121 facing the inner surface 11c of the outer wall surface member 11. The lock mechanism 14 is composed of these convex portions 112 and concave portions 122.

In the unfolded state, the pushing surface portion 121 is sandwiched by the one end portions 11a, 11a of the pair of outer wall surface members 11, 11. At this time, by fitting the convex portion 112 and the concave portion 122, relative movement between the pair of outer wall surface members 11, 11 and the slide member 12 is blocked, and the spacer 1 is locked in the expanded state. As a result, the outer wall surface member 11 of the spacer 1 is locked in the expanded state, so that it is possible to maintain the pressed state against the two holding target surfaces E1 and E1. In addition, the convex portion 112 and the concave portion 122 are engaged with each other by making a "click" sound and feel, so that the operator can easily perceive that the spacer 1 is in the completed deployment state.

The convex portion 112 and the concave portion 122 shown in the present embodiment are curved in an arc shape along the Y1-Y2 direction. Therefore, the convex 112 and the concave 122 can smoothly perform both the fitting operation and the fitting releasing operation along the curved surface along the Y1-Y2 direction. The convex 112 and the concave 122 may be formed in the height direction of the spacer 1, or may be partially formed in the height direction of the spacer 1.

The spacer 1 may have an operation portion for pulling out and operating the slide member 12 to bring it into a contracted state. FIG. 8 is a perspective view showing an example of the operation unit.
The operation portion shown in FIG. 8 is configured by the through hole 15 provided in the push surface portion 121. Using the jig 100 having the hook-shaped portion 101 that can be inserted into the through hole 15, after inserting and locking the hook-shaped portion 101 in the through hole 15, the jig 100 is pulled toward the front to slide the slide members 12 into a pair. Can be pulled out from between the outer wall surface members 11, 11. Thereby, the spacer 1 can be easily reduced. For example, as compared with a case where the operating portion is formed by a protrusion such as a knob and the protrusion is configured to be pulled by a tool such as a finger or pliers, the through hole 15 is projected on the spacer 1 in the expanded state. No part is formed.

FIG. 9 is a perspective view showing another embodiment of the spacer according to the present invention. Portions having the same reference numerals as those of the spacer 1 shown in FIGS. 1 to 4 show portions having the same configuration. The description above is based on the above description and is omitted here.
The spacer 1A shown in FIG. 9 has a plurality of slits 113 in the pair of outer wall surface members 11, 11. The slits 113 are arranged correspondingly between the movable connecting members 13 that are adjacent to each other along the moving direction (Y1-Y2 direction) of the slide member 12. As a result, the weight of the spacer 1A is reduced.

Each slit 113 extends along the moving direction (Y1-Y2 direction) of the slide member 12 between the adjacent movable connecting members 13 and 13, and is in the height direction (Z1-Z2 direction) of the outer wall surface member 11. Is provided in multiple. The outer wall surface member 11 has the curved portion 111 between the adjacent movable connection members 13 and 13, but the spring constant of the curved portion 111 can be adjusted by appropriately setting the number of slits 113, the slit width, and the like. it can. Thereby, the pressing load applied by the outer wall surface member 11 can be adjusted.

FIG. 10 is a perspective view showing still another embodiment of the spacer according to the present invention. Portions having the same reference numerals as those of the spacer 1 shown in FIGS. 1 to 4 show portions having the same configuration. The description above is based on the above description and is omitted here.
The spacer 1B shown in FIG. 10 has a plurality of lightening portions 114 on the pair of outer wall surface members 11, 11. The lightening portion 114 is arranged correspondingly between the movable connecting members 13 and 13 that are adjacent to each other along the moving direction of the slide member 12 (Y1-Y2 direction). The lightening portion 114 forms an opening larger than the slit 113 in the outer wall surface member 11. Therefore, the outer wall surface member 11 has a lattice frame shape, and the spacer 1B is further reduced in weight.

The lightening portion 114 shown in FIG. 10 is formed so as to open in a substantially rectangular shape, but the specific shape of the lightening portion 114 is the connection target of the outer wall surface member 11 and the movable connection member 13 or the holding target. There is no limitation as long as it does not affect the contact with the surface. Since the outer wall surface member 11 having the lightening portion 114 can reduce the contact area with the holding target surface, the spacer 1B is suitable for applications where it is desired to avoid contact with the holding target surface in a large area. Can be used.

Further, since the lightening portion 114 of the spacer 1B has a large opening, a fluid (gas, liquid) can flow through the lightening portion 114. Therefore, the spacer 1B can also cool or heat the holding target surface, for example, by circulating a cooling fluid or a heating fluid between the slide member 12 and the holding target surface.

11 is a sectional view taken along the line AA shown in FIG. As shown in FIG. 11, the dimension H1 of the slide member 12 in the height direction (Z1-Z2 direction) of the spacer 1B is formed smaller than the dimension H2 of the outer wall surface member 11 in the height direction (Z1-Z2 direction). ing. The upper end and the lower end of the pressing surface portion 121 have a shape in which the central portion in the width direction (X1-X2 direction) is recessed according to the height of the slide member 12. Thereby, even when the spacer 1B is in contact with the wall surface (not shown) on both surfaces in the height direction (Z1-Z2 direction), sliding between the wall surface and the slide member 12 can be reduced or avoided, It is possible to smoothly perform the reciprocating movement of the slide member 12 to bring it into the deployed state or the contracted state. Further, it is possible to easily circulate the cooling fluid or the heating fluid over the entire length of the spacer 1B by utilizing the space of the depressed central portion. The configuration of the slide member 12 shown in FIGS. 10 and 11 can be similarly applied to the slide members 12 of the spacers 1 and 1A.

Next, a specific application example of the spacers 1, 1A, 1B described above will be described.
12 to 14 show an example in which the spacers 1, 1A and 1B according to the present invention are applied to a battery device. FIG. 12 is a perspective view showing an exploded part of the battery device according to the present invention. FIG. 13 is an exploded perspective view showing a part of a battery cell group in the battery device according to the present invention. FIG. 14 is a front view showing the internal structure of the battery device according to the present invention. The directions shown in FIGS. 12 to 14 correspond to the directions shown in FIGS. 1 to 11.
The battery device 2 shown in the present embodiment includes an exterior body 20, a battery cell group 3 accommodated in the exterior body 20, and a spacer 1, 1A or 1B accommodated in the exterior body 20.

The outer casing 20 is made of a rigid body such as aluminum or aluminum alloy and is formed in a square tubular shape. Both ends of the exterior body 20 in the length direction (Y1-Y2 direction) are opened in a horizontally long rectangular shape. The exterior body 20 has an upper wall 21, a lower wall 22, and two side walls 23, 23 that face each other in the X1-X2 direction.

The two side walls 23, 23 are provided with temperature control medium channels 24, 24 through which the temperature control medium flows, respectively. Thereby, the inner surface 23a of the side wall 23 constitutes a heat exchange surface with the temperature control medium in the temperature control medium flow path 24. The temperature control medium flow path 24 in each side wall 23 extends over the entire length of the exterior body 20 in the longitudinal direction.

As the temperature control medium, generally, cooling air or a cooling liquid for cooling a battery cell, which will be described later, housed in the outer casing 20 is used, but a predetermined temperature for heating the battery cell is used as necessary. It is also possible to use air or liquid heated to temperature.

The temperature control medium flow path 24 shown in the present embodiment is provided inside the side wall 23. For this reason, it is not necessary to process the groove or the like for constructing the temperature control medium flow path 24 on the exterior body 20 later, and the exterior body 20 can be made compact, so that the battery device 2 can be made compact. Is possible. Further, although not shown, the temperature control medium flow path 24 inside the side wall 23 may be configured by a groove recessed from the outside of the side wall 23, for example. In this case, by covering the groove from the outside of the side wall 23 with a plate or the like, a channel through which the temperature control medium can flow is formed inside the side wall 23. Furthermore, the temperature control medium flow path 24 inside the side wall 23 may be formed by a pipe having heat conductivity. In this case, the side wall 23 provided with the temperature control medium flow path 24 is configured by embedding or fixing the pipe in the side wall 23 in a heat exchangeable manner.

Such an exterior body 20 can be formed as an extrusion molded product having the Y1-Y2 direction as the extrusion direction by forming the exterior body 20 in the same shape along the Y1-Y2 direction. Thereby, the exterior body 20 can be easily formed. Further, since the tubular outer casing 20 made of an extrusion molded product does not have a joint portion in which the plate materials are joined to each other, variations in assembly and thermal distortion due to the joint portion do not occur. Moreover, the stress when the battery cell group 3 is pressed against the side wall 23 by the spacer 1, 1A or 1B does not concentrate on the joint portion and cause distortion. Therefore, the battery device 2 having the exterior body 20 whose shape is stable can be configured.

As shown in FIGS. 12 and 13, the battery cell group 3 is formed by stacking a plurality of rectangular parallelepiped battery cells 30 made of, for example, a lithium ion secondary battery along the Y1-Y2 direction. Although not shown in FIG. 12 and FIG. 13, insulating separators are arranged between the battery cells 30, 30 adjacent to each other in the stacking direction, and are sandwiched between the adjacent battery cells 30, 30. The battery cell 30 is configured by housing an electrode body in a cell case made of aluminum, an aluminum alloy, or the like, and has a pair of positive and negative electrode terminals 31, 31 on the upper surface. The electrode terminals 31, 31 of the two battery cells 30, 30 adjacent to each other in the stacking direction are electrically connected by the bus bar 32. Thereby, all the battery cells 30 of the battery cell group 3 are electrically connected in series or in parallel.

The battery cell group 3 composed of a plurality of stacked battery cells 30 is inserted into the exterior body 20 while sliding in the Y1-Y2 direction. In order to maintain the stacked state of the battery cells 30, the battery cell group 3 may be integrated by collectively restraining the battery cells 30 in the stacked state by a restraint band or the like not shown. The battery device 2 of the present embodiment accommodates two battery cell groups 3 and 3 arranged side by side in the X1-X2 direction in the exterior body 20.

A heat transfer sheet 25 is arranged between the battery cell group 3 and the inner surface 23 a of the side wall 23. The heat transfer sheet 25 may be formed long along the stacking direction of the battery cells 30, or may be divided into a plurality of pieces corresponding to each battery cell 30. Further, the heat transfer sheet 25 before the battery cell group 3 is housed in the exterior body 20 may be attached to the battery cells 30 in advance, or may be attached to the inner surface 23 a of the side wall 23 in advance. .. The heat transfer sheet 25 comes into close contact with both the battery cells 30 and the inner surface 23a of the side wall 23 when the battery cell group 3 is pressed against the side wall 23 by the spacer 1, 1A or 1B described later. This stabilizes the heat exchange contact state between each battery cell 30 and the inner surface 23a of the side wall 23, and at the same time enables more efficient heat exchange.

The battery cell groups 3 and 3 housed in the exterior body 20 are clamped in the exterior body 20 along the Y1-Y2 direction by the end plates 26 arranged at both ends of the exterior body 20 in the Y1-Y2 direction. It will be housed in a closed state. In FIG. 12, only one of the two end plates 26, 26 is shown. The end plates 26 are fixed to both end surfaces of the outer casing 20 by bolts (not shown).

The end plate 26 is formed of a metal such as aluminum or aluminum alloy, a resin such as engineering plastic, or a rigid body such as a composite of these metals and resin. The end plate 26 may internally have a communication channel (not shown) that communicates with the temperature control medium channel 24. As a result, the end plate 26 can be used to efficiently flow the temperature control medium inside the exterior body 20.

As shown in FIG. 14, in the battery device 2, the spacer 1, 1A or 1B is arranged between the two battery cell groups 3 and 3 in the exterior body 20. In the battery device 2 according to the present embodiment, after one end surface (end surface on the Y1 direction side) of the exterior body 20 is sealed by the end plate 26, the two battery cell groups 3 and 3 are housed in the exterior body 20. To be done. Then, the spacer 1, 1A or 1B in the reduced state is inserted between the battery cell groups 3, 3. At this time, the spacer 1, 1A or 1B is inserted into the exterior body 20 along the Y1 direction from the side where the pressing surface portion 121 is not arranged.

The spacers 1, 1A or 1B in the contracted state inserted between the battery cell groups 3 and 3 hit the end plate 26, and thereafter, as described above, the slide member 12 is pushed in to operate and the pair of outer wall surface members is pushed. By unfolding 11, 11, the two battery cell groups 3, 3 can be separated and pressed against the two opposite side walls 23, 23 as shown by the white arrow in FIG. That is, in this case, the surface facing the two battery cell groups 3 and 3 becomes the holding target surface. Since the spacer 1, 1A or 1B can apply a pressing load to each of the battery cells 30 of the battery cell groups 3 and 3 at once by simply moving the slide member 12 in the Y1 direction and expanding the same. The battery cell groups 3 and 3 can be quickly and easily held and accommodated in the exterior body 20. Moreover, according to this configuration, it is possible to simultaneously hold the two battery cell groups 3 and 3 in the exterior body 20 with only one spacer 1, 1A or 1B.

Here, the arrangement relationship between each battery cell 30 of the battery cell group 3 and the movable connection member 13 will be described with reference to FIGS. 15 and 16. FIG. 15 is an enlarged plan view showing an example of the positional relationship between the spacers and the battery cells in the battery device according to the present invention. FIG. 16 is an enlarged plan view showing another example of the positional relationship between the spacers and the battery cells in the battery device according to the present invention. 15 and 16 show an example in which the spacer 1 is used, the same applies to the other spacers 1A and 1B.

In the example shown in FIG. 15, the movable connecting members 13 of the spacer 1 are arranged in a one-to-one correspondence with the positions of the battery cells 30 forming the battery cell group 3. Therefore, since the contact portion between the outer wall surface member 11 and the battery cell 30 is supported by the movable connecting member 13, the spacer 1 can apply a stable pressing load to the battery cell 30. Therefore, each battery cell 30 can be efficiently pressed toward the side walls 23, 23, and more efficient heat exchange with the temperature control medium can be performed.

In the example shown in FIG. 16, the movable connection members 13 of the spacer 1 are arranged in a one-to-one correspondence between the battery cells 30 adjacent to each other in the stacking direction. Therefore, the contact portion between the outer wall surface member 11 and the battery cell 30 is the curved portion 111 of the outer wall surface member 11. Thereby, the spacer 1 can elastically contact the battery cell 30 by the curved portion 111. Therefore, the tolerance of each battery cell 30 can be absorbed by the curved portion 111, and even in the battery cell group 3 having dimensional variations in the battery cells 30, an appropriate pressing load can be applied by the spacer 1.

The two battery cell groups 3 and 3 in the exterior body 20 can also be pressed by one spacer 1, 1A or 1B, respectively. 17A and 17B are diagrams illustrating another arrangement relationship between the spacer and the battery cell group in the battery device according to the present invention. 12 to 14 have the same reference numerals as those of the same components. The description above is based on the above description and is omitted here.

The battery device 2A shown in FIG. 17A has a temperature control medium flow path 24 in the lower wall 22 of the exterior body 20. Between the two battery cell groups 3 and 3 in the exterior body 20, a central wall 27 that partitions the accommodation space of the battery cell group 3 in the exterior body 20 is provided. In this case, by arranging the two spacers 1, 1A or 1B between the upper wall 21 and the battery cell groups 3, 3, respectively, the two spacers 1, 1A, 1B respectively form the battery cell groups 3, 3 respectively. It can be pressed against the lower wall 22.

A battery device 2B shown in FIG. 17B has a temperature control medium flow path 24 in a central wall 27 inside the outer casing 20. In this case, by disposing the two spacers 1, 1A or 1B between the side walls 23, 23 and the battery cell groups 3, 3, respectively, the two spacers 1, 1A, 1B are respectively arranged by the battery cell groups 3, 3, respectively. Can be pressed towards the central wall 27.

Although not shown, the battery device may have only one battery cell group 3 in the exterior body 20. In this case, the battery cell group 3 is pressed against either the upper wall 21, the lower wall 22 or the side walls 23, 23 by the one spacer 1, 1A or 1B.

FIG. 18A is a partially cutaway perspective view showing still another embodiment of the spacer according to the present invention. FIG. 18B is an enlarged view of part B in FIG. 18A. The directions shown in FIGS. 18A and 18B correspond to the directions shown in FIGS. 1 to 4.
In the spacer 1C shown in FIGS. 18A and 18B, the slide member 12C in the spacers 1, 1A and 1B is not a solid plate member but a hollow member having a hollow portion 123. Therefore, the spacer 1C functions as an attachment component that uses, for example, the hollow portion 123 of the slide member 12C to perform wiring, insertion of pipes, circulation of air, liquid, and the like.

The slide member 12C of the spacer 1C shown in FIGS. 18A and 18B is formed in a substantially rectangular tube shape, and has outer wall surface members 11 connected to the four surfaces by a plurality of movable connection members 13, respectively. The spacer 1C is inserted into the opening 201 with the inner surface of the rectangular opening 201 formed in the member 200 as a holding target surface. After the outer wall surface member 11 abuts on the abutting surface 202 at the back of the opening 201, the outer wall surface member 11 is expanded by pushing the slide member 12C in the insertion direction (Y1 direction). .. As a result, the spacer 1C as an attachment component is held in the opening 201 of the member 200. The spacer 1C is held by pressing the inner peripheral surface of the opening 201 by the outer wall surface members 11 in the expanded state, so that the spacer 1C absorbs the tolerance of the opening 201 to the opening 201. Can be installed stably.

In the spacer 1C, the outer wall surface member 11 and the inner peripheral surface of the opening 201 may be fixed to each other with a double-sided tape, an adhesive, or the like (not shown). Further, the outer wall surface member 11 may be provided only on any two of the four surfaces of the guide member 12A that are arranged in parallel.

19 to 22 show an example in which the spacer according to the present invention is applied to a portable terminal accommodation device. FIG. 19 is a perspective view showing a portable terminal accommodation device according to the present invention. FIG. 20 is an exploded perspective view of the portable terminal accommodation device according to the present invention. FIG. 21 is an enlarged perspective view showing a part of the portable terminal accommodation device according to the present invention. FIG. 22 is a vertical sectional view showing the internal structure of the portable terminal accommodation device according to the present invention.
The mobile terminal housing device 4 shown in the present embodiment has a case 41, an outer lid 42, and a spacer 1D.

The case 41 has a size capable of accommodating a mobile terminal 300 such as a smartphone or a tablet terminal, and is formed in a box shape with one surface open. The inside of the case 41 constitutes a housing portion 411 of the mobile terminal 300.
The outer lid 42 is a member that covers the open surface of the case 41. The outer lid 42 is formed in a rectangular frame shape, and has a rectangular opening window 421 that can expose the screen 301 of the mobile terminal 300 housed in the case 41 to the outside. The opening window 421 has a size that exposes substantially the entire screen 301 of the mobile terminal 300 to the outside, but is formed smaller than the outer shape of the mobile terminal 300.

The spacer 1D is arranged between the mobile terminal 300 housed in the case 41 and the back plate 412 of the case 41. The spacer 1D of the present embodiment has a form in which one of the pair of outer wall surface members of the spacers 1, 1A to 1C described above is formed by the back plate 412 of the case 41. The other outer wall surface member 11D of the pair of outer wall surface members is arranged so as to contact the back surface of the mobile terminal 300.

The slide member 12D of the spacer 1D is arranged along the back surface of the mobile terminal 300 so as to extend in the vertical direction in the figure. The slide member 12D and the back plate 412, and the slide member 12D and the outer wall surface member 11D are connected by swingable movable connection portions 13D.

As shown in FIG. 22, the portable terminal accommodating device 4 configured in this manner stores the portable terminal 300 in the accommodating portion 411 provided in the case 41 between the outer lid 42 and the outer wall surface member 11D of the spacer 1D. Accommodate. After the outer lid 42 is attached to the case 41, the slide member 12D is moved along the Y1 direction in the drawing to open the spacer 1D. As a result, the outer wall surface member 11D of the spacer 1D moves away from the mobile terminal 300 and presses the mobile terminal 300 toward the opening window 421. Therefore, even if the thickness of the mobile terminal 300 varies depending on the type and the like, the mobile terminal housing device 4 brings the mobile terminal 300 into close contact with the outer lid 42 according to the thickness, thereby opening the screen 301 in the open window. 421 can be aligned and held.

In the present embodiment, the contact pin 126 is provided at the upper end of the slide member 12D so as to be movable in the Y1-Y2 directions. The tip portion 126 a of the contact pin 126 is fitted and supported by the upper surface plate 414 of the case 41. A disk-shaped adjusting plate 124 is rotatably screwed to the contact pin 126 via a coil spring 125. The coil spring 125 biases the adjusting plate 124 in the Y1 direction. The adjusting plate 124 is arranged in the opening 115 formed in the outer wall surface member 11D, and is configured to be rotatable through the opening 115. Therefore, when the adjusting plate 124 is rotated in one direction, the slide member 12D moves in the Y1 direction to be in an expanded state, and the outer wall surface member 11D presses the screen 301 of the mobile terminal 300 against the opening window 421.
