Description

  The present invention relates to a battery support that supports a battery mounted on, for example, an electric vehicle.

  Conventionally, as a battery fixing structure for fixing a battery mounted on an electric vehicle, a battery is disposed between two opposing support members, and then these two support members are tightened with bolts or the like. There is known one that fixes a battery between them (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 10-149805

  However, in such a conventional fixing structure, when a plurality of batteries are stacked and fixed, in order to cope with a variation in the number of stacked layers and a difference in thickness dimension of each battery, a manual operation is required. After alternately arranging the supporting members and one battery until the desired number of layers is reached, it is necessary to fasten the whole with bolts etc. and fix each battery between the supporting members, so assembly work takes time, There is a problem of poor productivity.

  On the other hand, in order to improve productivity, it is considered effective to form a plurality of support members that support the battery by integral molding in advance and eliminate the assembly work of the support members. However, since the support member formed by such integral molding can only support a battery having a predetermined shape, in order to support a battery having a different thickness, the thickness dimension of the battery Accordingly, there is a problem that a cutting and cutting work is required according to the above, and dust (particularly, glass cutting powder for a glass fiber reinforced product) is generated, resulting in a product defect. In addition, such a support member has a problem that it cannot flexibly cope with fluctuations in the number of stacked batteries. Furthermore, it is necessary to provide a clearance that takes into account the battery thickness tolerance due to the requirement of assembly workability in such a support member, so that long-term reliability decreases due to backlash during vibration, and the clearance generated as a clearance is charged and discharged. Problems such as a heat insulating layer that prevents heat generation from occurring.

  Therefore, an object of the present invention is to provide a battery support that can support a battery simply and firmly in an assembling process and can prevent generation of dust during assembly.

  In order to achieve the above object, a battery support according to the present invention has a pair of opposing holding parts and a connecting part for connecting the pair of holding parts, and the pair of holding parts are brought close to each other by a fixing means. A battery support for holding the battery between the pair of holding parts, wherein at least a part of the connecting part is configured to be damaged when the pair of holding parts are approached by the fixing means. The pair of sandwiching portions are configured to approach each other due to breakage of the connecting portion and sandwich the battery.

  As described above, the battery support according to the present invention makes the pair of holding parts accessible only by breakage of the connecting part, and holds the battery. The battery can be firmly supported, and a cutting step by cutting and cutting becomes unnecessary, and generation of dust during assembly can be prevented. In addition, since the battery support according to the present invention can firmly support the battery, it is possible to ensure reliability in a high-vibration environment required for vehicle applications and the like.

  The battery support according to the present invention may further include one or more intermediate portions provided between the pair of sandwiching portions so as to face each of the pair of sandwiching portions, and the connecting portions are adjacent to each other. Each of the sandwiching part and the intermediate part is connected, and when the connecting part is broken, the sandwiching part and the intermediate part approach each other, and the battery is inserted between the sandwiching part and the intermediate part adjacent to each other. It is preferable to be configured so as to be sandwiched. Thus, by providing one or more intermediate portions between the pair of sandwiching portions, the number of battery stacks can be flexibly changed according to the desired battery capacity, simply by increasing the number of intermediate portions, Thereby, it can be applied to a multi-product manufacturing line in which the number of battery stacks changes.

  Further, in the battery support according to the present invention, the pair of sandwiching portions and the connecting portion are integrally formed, and at least a part of the connecting portion has a direction orthogonal to the approaching direction of the pair of sandwiching portions. A convex portion that is curved and protrudes is formed, and at least one of the base end portions of the convex portion or at least one part of the surface of the convex portion that faces the pair of sandwiching portions is formed by the fixing means. It is good also as being formed so that it may be damaged when approaching the clamping part. As described above, when the pair of sandwiching portions and the connecting portion are formed by integral molding, the assembly work of the battery support itself is not necessary, and the shape of the battery support is maintained when the battery is mounted (when temporarily assembled). Therefore, productivity and workability can be improved. In addition, since the battery can be clamped and fixed only by a simple operation of bringing the pair of clamping parts closer, assembly can be automated, thereby further improving productivity.

  Furthermore, in the battery support according to the present invention, the pair of sandwiching portions are configured as separate bodies, and one sandwiching portion is formed with a projecting portion projecting toward the other sandwiching portion, An insertion hole into which the protruding portion can be inserted and an end of the protruding portion inserted into the insertion hole can be brought into contact with the other holding portion, and when the pair of holding portions are brought close by the fixing means A rib portion configured to break, and the connecting portion is configured by the protruding portion and the rib portion, and the protruding portion is inserted into the insertion hole and contacts the rib portion. In this state, the battery can be stored between the pair of sandwiching portions, the pair of sandwiching portions are brought close to each other by the fixing means, and the protruding portion breaks the rib portion and further enters the insertion hole. In the inserted second state Te is by the pair of holding portions may be configured to sandwich the battery. As described above, the pair of holding portions are configured separately, and the protruding portion formed in one holding portion can be inserted into the insertion hole formed in the other holding portion and can contact the rib portion. With this configuration, in the first state where the protruding portion is in contact with the rib portion, temporary assembly can be performed by so-called snap fit (assembly without using an adhesive or the like), and when the battery is mounted (temporary Since the shape of the battery support is maintained during assembly), workability can be improved.

  Furthermore, in the battery support according to the present invention, the breakage portion of the connecting portion may be formed thinner than other portions, or may be formed at a position aligned with the weld line. . In this way, since the breakage part of the connecting part is formed thin or formed at a position aligned with the weld line, damage is induced, so that the connecting part can be accurately broken at a desired position. It is possible to prevent dust generation and reduce product defects. Here, the weld line refers to a thin line (fluid boundary) generated in a fusion-bonded part of the molten resin flow in the mold during injection molding. Since the weld line is a portion where the flow boundary is fused, the weld line has a lower strength than the other portions and can be easily broken and broken along the generated thin line. In addition, for example, when the battery support is formed of a short glass fiber reinforced resin, there is little or no glass fiber straddling the flow boundary, so breakage along the weld line causes generation of glass fiber fragments. Can be prevented.

  As described above, according to the battery support according to the present invention, the battery support that can support the battery easily and firmly in the assembly process and can prevent the generation of dust during the assembly. Can be provided.
