The present invention relates to a battery module support device, and more particularly, by placing the module in a vertical direction when mounting the battery module (hereinafter referred to as a module) in a vehicle, the bending caused by the weight of the module and the inter-cell connection The present invention relates to a battery module supporting apparatus capable of reducing stress and reducing weight and manufacturing cost of supporting components since the support structure is not required in the middle of the module.

In general, a battery of a vehicle is an electric provision part for each element of the vehicle, and the charging and discharging is repeated by the electric load and the power generation unit of the vehicle.

The temperature rise of the battery during this process causes a change in the internal resistance of the battery, the electrical performance is degraded, and the problem is that the efficient electrical management of the vehicle is not achieved.

In particular, with the recent development of electric vehicles and high voltage batteries of 36V type, the practical necessity of cooling the internal temperature of the battery to an appropriate level has increased.

On the other hand, Japanese Patent Laid-Open No. 2005-280649 discloses a structure in which the axial direction of the modules is arranged in the horizontal direction on the ground in the case of a plurality of modules mounted in a vehicle.

However, in the above structure, the central portion of the module is bent by the weight of the module, causing stress to the connecting portions of the cells constituting the module, which is a factor that impairs durability.

In addition, Japanese Patent Laid-Open No. 2000-223096 discloses a connection structure of a module and its component parts, and it can be seen that a plurality of parts are connected to each other to easily bend the center part due to its own weight or vibration.

As a solution to the above problem, Japanese Patent Laid-Open No. 2005-332829 discloses a supporting structure called a fixed bulk head supporting the middle portion (two locations) of the module as well as the supporting structure at both ends of the module.

However, such a structure causes the module support structure to be duplicated, resulting in an increase in dimensions, weight, mold cost, parts cost, assembly cost, and the like.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and provides a structure in which the axial direction of the module is disposed perpendicular to the ground when a plurality of modules are mounted in a vehicle, thereby simplifying and compactly storing and assembling the modules. It is an object of the present invention to provide a battery module support device capable of improving the performance and reducing the weight, mold cost, parts cost, and assembly cost of the supporting parts.

The present invention for achieving the above object in the battery module support device,

A support holder in which a storage space for accommodating a plurality of battery modules is formed, an opening is formed in an upper portion, and a support groove in which a lower end and a terminal of the module are inserted in a bottom surface thereof; And a cover means for covering the upper end of the support holder and fixing and supporting the upper end of the module.

In a preferred embodiment, the cover means is an end plate formed with a support groove into which the upper end of the module and the terminal are inserted, and the support groove is symmetrical with the support groove formed on the bottom of the holder.

In a more preferred embodiment, the inlet and exhaust holes are formed at the bottom edges of the end plate and the support hole, and cooling air is introduced and discharged through the intake and exhaust holes.

In addition, the holder is characterized in that the axis of the module is installed perpendicular to the ground or parallel to the rear seatback.

In addition, the support holder and the upper cover means and characterized in that consisting of the lower cover means.

In addition, the support holder and the upper and lower cover means is formed integrally.

In addition, any one of the support holder and the upper and lower cover means is formed integrally.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a support apparatus according to the present invention is composed of a support holder 10 having an opening 23 formed thereon, an end plate 11 and an intake plate 12 installed on an upper end of the support holder 10.

As shown in FIG. 5, a storage space is formed inside the support holder 10 so that a plurality of modules 13 can be inserted in a vertical direction, and one side of the module 13 is disposed on a bottom surface of the holder 10. The support groove 17 into which the terminal 14 and the end of the module 13 can be inserted is formed.

In this case, the terminals 14 of the modules 13 having different polarities are bolted by the bus bars 21, and the lower ends of the modules 13 are fixed, and a plurality of terminals are provided on the bottom edge of the support holder 10. The exhaust hole 16 is formed.

Fig. 10 shows an embodiment in which a plurality of intake holes and exhaust holes are provided on the side of the support holder, and the positions of the intake holes and the exhaust holes can be set on any other surface of the holder.

As shown in FIG. 7, the end plate 11 is provided with a support groove 17 into which the upper end portion and the one-side terminal 14 of the module 13 can be inserted. The terminal 14 is bolted by the bus bar 21 so that the upper end of the module 13 is fixed.

As shown in FIG. 2, a plurality of intake holes 15 are formed at edges of the intake plate 12 and the end plate 11, and cooling air is blown through the intake hole 15 and the exhaust hole 16. Hot air is introduced and discharged.

Referring to the assembly method and the use state of the module 13 support device according to the present invention by such a configuration as follows.

1) Assembly method

As shown in FIG. 1, the module 13 is inserted into the holder 10 through the upper opening 23, and the end of the module 13 is inserted into the support groove 17 formed in the bottom of the holder 10. Next, the terminals 13 of the modules 13 having different polarities are fixed by bolting by the busbars 21.

Then, the upper end of the module 13 is inserted into the support groove 17 of the end plate 11, and then the terminal 14 of the module 13 having a different polarity is bolted and fixed by the busbar 21. At the same time, electrical connection of the module 13 is performed.

Finally, when the intake plate 12 is bolted to the upper surface of the end plate 11, the assembly is completed.

2) State of use

The support device according to the present invention may be installed to be inclined such that the axis of the module 13 is installed perpendicular to the ground, or parallel to or close to the seatback 20 of the vehicle.

The configuration as described above may be made by the horizontal mounting surface of the support device is formed to be inclined upward by the inclination angle (vertical plane reference) of the seatback 20 in the floor panel 18 of the vehicle.

Self-weight of the module 13 is applied to the support groove 17 of the holder 10 from the end of the module 13 inserted into the holder 10, resulting in a module 13 generated when placed horizontally on the ground The stress at the cell-to-cell connection due to the bending of can be greatly reduced.

In addition, by inserting the shock absorbing material 22 into the support groove 17 formed in the bottom surface of the holder 10, it is possible to reduce the impact on the module 13, the support portion in the middle of the module 13 Since it does not exist, the cooling area can be expanded and the cooling performance can be improved as compared with two conventional support portions.
