  Since the protection member is arrange | positioned so that the battery tray of this invention may respond | correspond to the bottom part of a some battery, it can prevent the drop-off | omission of the battery when a battery tray fuse | melts. As a result, when battery trays are stacked, the fired battery falls to the lower battery tray, and the fire of the dropped battery is prevented from burning into the battery stored in the lower battery tray. Can do. Moreover, since the battery tray is composed of the first tray and the second tray, the shape of the first tray to which the protection member is attached can be simplified. That is, it is easy to secure a flat portion for attaching the protection member to the first tray, and the protection member can be easily fixed.

  In the battery tray of the present invention, the second tray includes a storage portion for storing the battery and an inclined portion provided at the back of the storage portion, and the interval between the inclined portions facing each other is as follows. It is preferable that the battery expands toward the opening, and the battery is stored upright in the storage portion while being surrounded by the opening and in contact with the inclined portion. According to this configuration, various types of batteries having different thicknesses and outer diameters can be accommodated while changing the height of the battery mounting position in the inclined portion. In this configuration, since the storage portion and the inclined portion are provided in the second tray, also in this configuration, the shape of the first tray can be simplified, and the protection member can be easily fixed.

  Moreover, it is preferable that the said 2nd tray is comprised by the upper tray which formed the said opening, and the intermediate | middle tray which formed the said accommodating part and the said inclination part. According to this configuration, when the upper tray and the intermediate tray are resin-molded, the mold structure corresponding to each is simplified. In addition, by changing the combination of the upper tray and the intermediate tray to one having a different opening shape or inclined shape, the range of battery thickness and outer diameter that can be stored can be widened.

  Further, it is preferable that the protection member is at least one plate-like or net-like member, and one piece of the protection member corresponds to a plurality of bottom portions of the batteries. According to this configuration, even if the lower tray partially melts due to the ignition of some of the batteries, if the protective member is fixed to the lower tray at a portion corresponding to the battery that is not ignited, the protective member is dropped. Can be prevented.

  The second tray is preferably replaceable. According to this configuration, the range of the thickness and the outer diameter of the battery that can be stored can be widened by changing the shape of the opening of the second tray and the shape of the inclined portion.

  The protective member is preferably covered with an insulating material. According to this configuration, when the protective member is made of a metal such as an iron plate, a short circuit when the battery contacts the protective member can be prevented.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a configuration diagram of a battery tray according to an embodiment of the present invention. This figure has shown the state which decomposed | disassembled the battery tray 1. FIG. The battery tray 1 includes a lower tray 10 that is a first tray, an intermediate tray 20 and an upper tray 30 that are second trays, and a protective member 2. As will be described later, the intermediate tray 20 may be omitted from the second tray, or the intermediate tray 20 and the upper tray 30 may be integrated.

  The lower tray 10 is used in a state where the protection member 2 is attached. Further, when in use, the intermediate tray 20 is stored in the lower tray 10, and the upper tray 30 is attached on the intermediate tray 20.

  FIG. 2 is a perspective view of the battery tray 1 in a use state. The upper tray 30 is attached so as to be surrounded by the inner walls of the four sides of the lower tray 10. In the state of this figure, the intermediate tray 20 (FIG. 1) is stored on the back side of the upper tray 30.

  Hereinafter, the battery tray 1 will be described for each component of the battery tray 1. FIG. 3A shows a plan view of the lower tray 10, and FIG. 3B shows a side view of the lower tray 10. 4 is a cross-sectional view taken along line AA in FIG. As shown in FIG. 3B, the lower tray 10 forms a standing side wall 11. As shown in FIG. 3A, the bottom 12 of the lower tray 10 is surrounded by four side walls 11. As shown in FIG. 4, a storage space 15 is formed inside the side wall 11. The storage space 15 is a space for storing the intermediate tray 20 (FIG. 1).

  As shown in FIGS. 3A and 4, a through hole 13 is formed in the bottom 12 of the lower tray 10. As will be described later, the through hole 13 is a hole through which an electrode for charging a battery stored in the battery tray 1 is inserted.

  FIG. 5A shows a plan view of the intermediate tray 20, and FIG. 5B shows a side view of the intermediate tray 20. The intermediate tray 20 is provided with a large number of battery storage portions 21, and each battery storage portion 21 can store one square battery.

  FIG. 6 shows an enlarged view of the battery storage unit 21. 6A is a plan view, and FIG. 6B is a cross-sectional view taken along the line BB in FIG. 6A. In FIG. 5 (a), the battery storage unit 21 is arranged in an inclined manner, but in FIG. 6 (a), it is shown vertically to facilitate understanding. In addition, the rectangular battery 9 when stored is shown by a two-dot chain line.

  In FIG. 6A, inclined portions 23 are formed at both ends in the width direction (arrow a direction) of the battery storage portion 21 so as to sandwich the through hole 22. In the present embodiment, the inclined portion 23 is not formed in the portion where the through hole 22 is formed. For this reason, the inclined part 23 in FIG. 6B shows the upper inclined part 23 in the inclined part 23 sandwiching the through hole 22 in the illustration in FIG.

  5 and 6 is an example, and a configuration in which the inclined portion 23 is not divided and the through hole 22 is formed in the inclined portion 23 may be employed.

  In FIG. 6 (b), the inclined portion 23 is formed on the back side (bottom surface side) of the battery housing portion 21, and the inclined surface 23a and the inclined surface 23b facing each other are formed in a V shape. The inclined surfaces 23a and 23b are formed so that the distance between the inclined surface 23a and the inclined surface 23b increases toward the upper side of the intermediate tray 20. The bottom surface of the prismatic battery 9 is placed on the inclined portion 23, and the position of the rectangular battery 9 in the height direction (arrow b direction) is determined by the inclined portion 23.

  Further, as described above, the inclined portion 23 in FIG. 6B is the upper inclined portion 23 among the inclined portions 23 sandwiching the through hole 22 in the illustration of FIG. 6A. . In the upper inclined portion 23, the prismatic battery 9 can be brought into contact with only the inclined surface 23a, and the lower inclined portion 23 can be brought into contact with only the inclined surface 23b to maintain the standing state. As shown in FIG. 5B, the storage property is better when it is in contact with both the inclined surface 23a and the inclined surface 23b.

  Moreover, although the inclination part 23 is illustrated in the example of V shape, the bottom part of the inclination part 23 which the square battery 9 does not contact | abut may have a curved surface shape, and may contain the horizontal surface. Further, a configuration including a curved surface is also conceivable with respect to the inclined surface with which the square battery 9 abuts. That is, the cross-sectional shape of the inclined portion 23 is not limited to a complete V shape, and may include a portion formed so that the interval between the inclined surface 3a and the inclined surface 3b facing each other is increased.

  Each battery housing portion 21 is provided with a through hole 22. As shown in FIG. 6B, the through hole 22 is formed so as to penetrate the bottom of the intermediate tray 20. In a state where the intermediate tray 20 is stored in the lower tray 10 of FIG. 4, the through hole 13 of the lower tray 10 corresponds to the through hole 22. In the chemical conversion step, an electrode is passed through the through hole 13 and the through hole 22, and the prismatic battery 9 is charged by sandwiching the prismatic battery 9 from above and below with another electrode lowered from above. Details of the charging will be specifically described later.

  FIG. 7 is a view showing the upper tray 30. FIG. 7A is a plan view and FIG. 7B is a side view. The upper tray 30 is formed by forming a large number of openings 31 in a flat plate member. When the intermediate tray 20 of FIG. 5 and the upper tray 30 of FIG. 7 are combined, one opening 31 corresponds to one battery storage portion 21 of the intermediate tray 20.

  FIG. 8 shows an enlarged view of the opening 31. 8A is a plan view, and FIG. 8B is a cross-sectional view taken along the line CC in FIG. 8A. In FIG. 7 (a), the openings 31 are arranged in an inclined manner, but in FIG. 8 (a), they are shown vertically for easy understanding. In addition, the rectangular battery 9 when stored is shown by a two-dot chain line.

  As shown in FIG. 8B, the opening 31 is formed so as to penetrate the upper tray 30 in the thickness direction. Further, as shown in FIG. 8A, a portion surrounded by a pair of vertical surfaces 32 and 33, horizontal surfaces 34 and 35, and inclined surfaces 36 and 37 is an opening 31, and the opening 31 is a polygon. It is formed into a shape. The inclined surfaces 36 and 37 are arranged at a pair of diagonal positions of the opening 31, that is, at a pair of diagonal positions of the stored rectangular battery 9. The horizontal surfaces 34 and 35 are restriction surfaces that restrict the movement of the battery in the width direction (arrow a direction), and the inclined surfaces 36 and 37 are 1 of the rotational movement of the battery in two directions (arrows c and d directions). It is a regulating surface that regulates rotational movement in the direction (arrow d direction).

  When the prismatic battery 9 is stored in the battery storage portion 21, the prismatic battery 9 is inserted into the battery storage portion 21 from the upper side of the opening 31 through the opening 31. In order to facilitate this insertion, a tapered surface 38 is provided above the opening 31. As shown in FIG. 8A, the position of the prismatic battery 9 is regulated by the horizontal surfaces 34 and 35 and the inclined surfaces 36 and 37. For this reason, the tapered surface 38 is preferably provided on at least each of these surfaces.

  FIG. 9A shows a plan view of the protection member 2, and FIG. 9B shows a side view of the protection member 2. The protection member 2 is a nonflammable member, and FIG. 9 shows an example of an iron plate. As shown in FIG. 9A, a large number of holes 3 are formed in the protection member 2. The hole 3 is a hole corresponding to the through hole 13 (FIGS. 3A and 4) of the lower tray 10. A plurality of small holes 4 are further formed in the protection member 2. The small hole 4 is a hole for attaching the protection member 2 to the lower tray 10 using a rivet, as will be described later.

  FIG. 10 shows the battery tray 1 in use. FIG. 10A is a plan view, and FIG. 10B is a side view. FIG. 10A corresponds to a plan view of the battery tray 1 shown in FIG. 2, and the intermediate tray 20 (FIG. 1) is accommodated between the lower tray 10 and the upper tray 30. In FIG. 10B, the upper tray 30 is placed on the upper side of the intermediate tray 20 (FIG. 1). For example, the upper tray 30 may be fixed by providing positioning pins on the upper tray 30 and fitting them into positioning holes provided on the lower tray 10.

  FIG. 11 is a rear view of the battery tray 1 and corresponds to a view of the battery tray 1 of FIG. A protective member 2 is attached to the back surface of the lower tray 10 by rivets 5. The rivet 5 is struck at the position of the small hole 4 (FIG. 9A) of the protection member 2. The hole 3 of the protection member 2 corresponds to the through hole 13 (FIGS. 3A and 4) of the lower tray 10.

  FIG. 12 shows an enlarged view of the opening 31 portion in FIG. 13A and 13B are cross-sectional views taken along the line DD in FIG. In FIG. 10A, the opening 31 portion is inclined, but is shown vertically in FIG. 12 for easy understanding. In addition, the prismatic battery 9 during storage is also illustrated.

  As shown in FIG. 13A, the intermediate tray 20 is disposed between the upper tray 30 and the lower tray 10. One battery storage portion 21 of the intermediate tray 20 corresponds to one opening 31 of the upper tray 30. When the prismatic battery 9 is inserted from above the opening 31, the bottom surface of the prismatic battery 9 comes into contact with the inclined surfaces 23 a and 23 b of the inclined portion 23, and the rectangular battery 9 is surrounded by the opening 31 in the battery housing portion 21. Stored.

  On the lower side of the rectangular battery 9, the through hole 22 of the intermediate tray 20 and the through hole 13 of the lower tray 10 correspond to each other. Further, the lower tray 10 has a protrusion 14 surrounding the through hole 13, and the hole 3 of the protection member 2 is engaged with the protrusion 14.

  As shown in FIG. 13A, in the chemical conversion step, there are an upper electrode 41 and a lower electrode 42 above and below the prismatic battery 9, respectively. During charging, the upper electrode 41 moves down and moves closer to the rectangular battery 9. The lower electrode 42 moves up and passes through the through holes 13 and 22 so as to approach the prismatic battery 9. In the state of FIG. 13B, the upper and lower electrodes 41 and 42 sandwich the rectangular battery 9. In this state, the prismatic battery 9 is charged, and after charging, the upper and lower electrodes 41 and 42 move in the opposite direction to the above and are separated from the prismatic battery 9.

  FIG. 14 shows a cross-sectional view taken along line EE of FIG. In this figure, a sectional view of the inclined portion 23 of the battery storage portion 21 of the intermediate tray 20 is shown. The intermediate tray 20 is a resin molded product, and the resin molded product needs to have a uniform thickness as much as possible in order to stabilize the shape after molding. For this reason, a lightening portion 24 is formed below the inclined portion 23.

  On the other hand, since the thinned portion 24 is formed, a flat portion cannot be secured below the inclined portion 23. 6 (a) and 6 (b), it is possible to secure a planar portion in a portion other than the inclined portion 23, but the area of the planar portion that can be secured by forming the through hole 22 is reduced. Therefore, when it is set as the specification which attaches the protection member 2 to the bottom part of the intermediate | middle tray 20, it becomes difficult to ensure the attachment surface of the protection member 2. FIG.

  In the present embodiment, the battery tray 1 is divided into a lower tray 10, an intermediate tray 20 and an upper tray 30. In this configuration, the lower tray 10 and the intermediate tray 20 can be formed separately and independently. For this reason, as shown in FIGS. 3A and 4, the surface and the back surface of the bottom 12 of the lower tray 10 can be flat except for the portion where the through hole 13 is formed. Therefore, it is possible to secure a sufficient flat portion for attaching the protection member 2 to the lower tray 10.

  FIG. 15 is a cross-sectional view showing the mounting specifications of the protection member 2. This figure corresponds to a sectional view of the bottom of the battery tray 1 in FIG. 10A, but the intermediate tray 20 is not shown. The through hole 3 of the protection member 2 is engaged with the protruding portion 14 that forms the through hole 13 of the lower tray 10.

  As shown in FIG. 3A, the lower tray 10 has a through hole 14 in addition to the through hole 13. Similarly, as shown in FIG. 9A, the protective member 2 has a small hole 4 in addition to the hole 3. As shown in FIG. 15, the small hole 4 of the protection member 2 corresponds to the position of the through hole 14 of the lower tray 10. A rivet 5 is struck so as to pass through the through hole 14 and the small 4. The rivet 5 is struck at the positions of the plurality of small holes 4 of the protection member 2, and thereby the protection member 2 is fixed to the lower tray 10.

  As shown in FIG. 15, in order to hit the rivet 5, a flat portion is required at the bottom of the lower tray 10. As described above, in the present embodiment, the battery storage portion 21 is formed on the intermediate tray 20 that is separate from the lower tray 10, thereby making it easy to secure a flat portion on the lower tray 10.

  Here, in the battery manufacturing process, normally, the battery does not ignite, but by forming the battery tray from a flame-retardant material, it is possible to prevent the battery tray from being combusted by the ignition of the battery. However, when the battery trays are stacked, if the battery tray melts due to the ignition of the battery, the fired battery may fall off the battery tray and fall to the lower battery tray. When the battery falls, the fire of the dropped battery may burn into the battery stored in the lower battery tray, and the combustion may spread. In the present embodiment, the protection member 2 is provided for preventing the battery from falling off when the battery tray is melted. For this reason, even if the battery is ignited, it is prevented from burning to the battery stored in another toilet.

  In addition, by providing the protection member 2, when the battery ignites, the battery does not fall and combustion can be stopped in a state where the battery stays at a certain position. For example, if the tray is formed of a flame retardant member, the spread of combustion in one tray can be prevented.

  Next, storage of rectangular batteries having different thicknesses will be described. FIG. 12 shows a state in which the rectangular battery 9 having a thickness t is stored in the battery storage unit 2. In this state, as shown in FIG. 14, the prismatic battery 5 is placed on the inclined surfaces 23a and 23b of the inclined portion 23 having a V-shaped cross section. That is, the prismatic battery 5 is on the inclined portion 23 and in the opening 21, thereby maintaining an upright state.

  On the other hand, the rectangular battery 5a shown by the two-dot chain line in FIG. 14 has a thickness t1, and is larger than the rectangular battery 5 having the thickness t. For this reason, the bottom surface of the prismatic battery 5 a is above the bottom surface of the prismatic battery 5. In this case, as shown in FIG. 12, the prismatic battery 5 a is inclined from the position of the prismatic battery 5 in the opening 21. That is, in the opening 21, the prismatic battery 5 a is kept upright while being rotated from the position of the prismatic battery 5. For this reason, in FIG. 14 which is an EE cross section of FIG. 12, the bottom surface of the prismatic battery 5a is not in contact with the inclined surface 23b, but in the portion of the FF cross section of FIG. It does not contact 23a but contacts the inclined surface 23b.

  That is, according to the battery tray 1 of the present embodiment, it is possible to store rectangular batteries having different thicknesses by changing the height of the mounting position on the inclined portion 23 and rotating the same. In this case, the battery storage unit 21 having the inclined surfaces 23a and 23b is required. As described above, in the present embodiment, the battery storage unit 21 is formed on the intermediate tray 20 separate from the lower tray 10. Yes. For this reason, it becomes easy to secure the flat portion of the lower tray 10 and the protection member 2 can be easily attached. Therefore, according to the present embodiment, in order to be able to store a wide variety of batteries, it is easy to attach a protective member even in a battery tray that requires a battery storage portion having an inclined surface, and safety is ensured. Is easy to secure.

  FIG. 16 is a cross-sectional view showing another example of the protective member. The protective member 2 shown in FIG. 9 is obtained by forming holes 3 and 4 in a plate-like member, whereas the protective member 6 shown in FIG. 16 is a net-like member. The projection 14 surrounding the through hole 13 shown in FIG. 15 corresponds to the position of the opening 7, and the rivet 5 shown in FIG.

  9 and 16, the protective member has been described as an example of a single plate-like or net-like member, but a plurality of protective members for one battery tray may be provided. In this case, it is preferable that one piece of the protective member corresponds to the bottom of the plurality of batteries. According to this configuration, even if the lower tray 10 is partially melted by the ignition of some of the batteries, the protective member is protected if the protective member is fixed to the lower tray 10 at a portion corresponding to a battery that is not ignited. Can be prevented from falling off.

  The protective member is preferably covered with an insulating material. Thereby, when the protective member is made of a metal such as an iron plate, a short circuit when the battery contacts the protective member can be prevented. The insulating material may be coated or affixed.

  In the above embodiment, the protective member is described as being fixed to the lower tray with rivets. However, the present invention is not limited to this, and various fixing means such as screw tightening may be used.

  Further, the protective member may be disposed in the mold during resin molding of the lower tray and molded integrally with the lower tray. According to this configuration, it is not necessary to separately fix the protective member with fixing means such as a rivet.

  In addition, the battery tray according to the present embodiment has been described with the example including the intermediate tray, but the configuration may be such that the intermediate tray is omitted. Also in this configuration, since the upper tray and the lower tray are separate parts, the shape of the lower tray can be simplified. For this reason, it is easy to secure a flat part for attaching the protection member to the lower tray, and the protection member can be easily fixed. In this configuration, the battery can be stored in a state where the opening of the upper tray surrounds the battery. In this case, the height of the upper tray may be increased so that the range in which the opening of the upper tray surrounds the battery in the height direction of the battery may be increased.

  In addition, as shown in FIG. 1, the battery tray according to the present embodiment has been described with an example in which the intermediate tray 20 and the upper tray 30 as the second tray are separate components. The one integrated with the tray 30 may be used. In this case, as shown in FIG. 14, if the inner peripheral surface of the opening 31 and the inner peripheral surface of the storage portion 21 are on the same plane, the structure of the mold in the case of resin molding is simplified.

  In addition, the battery tray according to the present embodiment can accommodate rectangular batteries having different thicknesses, but the thickness range is limited by the shape of the opening of the upper tray. A plurality of types of upper trays having different opening shapes may be prepared in order to cope with a wider range of prismatic battery thicknesses. In this way, the thickness range of the prismatic battery that can be accommodated can be widened by simply replacing the upper tray while sharing the lower tray.

  Similarly, in order to accommodate a wide range of square battery width dimensions, the use of an upper tray having a different opening shape in the width direction makes it possible to widen the range of width of the prismatic battery that can be accommodated. Furthermore, an upper tray corresponding to thickness and width may be used in combination.

  Moreover, although the said embodiment demonstrated the example of the tray for storage of a square battery, it makes it possible to store a cylindrical battery by changing the shape of the inclined surface of the intermediate tray and the shape of the opening of the upper tray. be able to. Specifically, in FIG. 7, the opening 31 of the tray 30 is circular, and in FIG. 14, the inclined portion 23 of the intermediate tray 20 is a conical surface, so that cylindrical batteries having different outer diameters can be accommodated. It becomes possible.

  In this case, the inclined portion of the intermediate tray is not limited to the conical surface, and the inclined portion 23 may be any shape as long as it extends toward the opening 31 of the upper tray 30 and can support the bottom of the battery at at least three points. It may be a pyramid surface. Further, the inclined portion 23 of the intermediate tray 20 is not limited to a planar shape, and for example, three or more ribs may be inclined. Similarly, the opening 31 of the upper tray 30 is not limited to a circle, and may be a polygon that is, for example, a triangle or more.

  Therefore, by making the upper tray and the intermediate tray exchangeable, the lower tray can be shared and replaced with one with a changed opening shape of the upper tray or with a changed shape of the inclined portion of the intermediate tray. By this, the range of the thickness and outer diameter of the battery which can be accommodated can be widened.

  Moreover, although the battery tray which concerns on this Embodiment demonstrated in the example used at a chemical conversion process, a use is not restricted to this. For example, it can be used when delivering a battery between manufacturing processes, or can be used for storing a battery.

  As described above, according to the present invention, it is possible to prevent the battery from dropping off when the battery tray is melted. Therefore, the battery tray according to the present invention is, for example, a tray for charging in a chemical conversion process, between the manufacturing process. It is useful as a tray for delivery by hand, or as a tray for storing batteries.
