Tray assembly for battery storage {Tray assembly for packing battery}

The present invention relates to a tray assembly for battery storage, and more particularly, in a tray assembly for storing a plurality of battery modules, the tray is configured in two layers so as to efficiently cool the heat generated from the battery. The present invention relates to a battery assembly tray assembly capable of arranging the wires by stacking the space as much as possible and providing a space in which the wires can be inserted.

Generally, a vehicle including an electric vehicle and a solar vehicle includes a plurality of battery modules 1 as shown in FIG. 1 for the purpose of starting or supplying power to an engine. The battery module 1 is composed of a plurality of batteries (1a) are connected in series, a plurality of batteries (1a) stacked between the buffer member (1b) at both ends, and then wound the band (1c) It is comprised by assembling the screw 1d. The battery module 1 is generally mounted under a rear trunk or a seat of a vehicle, and it is important to maintain a firm fixed state without shaking the vehicle body during vibration or driving. In addition, a large amount of heat is generated in the process of generating power in the battery 1a, and this heat must be cooled because it reduces the electrochemical performance of the battery 1a. To this end, a tray assembly having a structure capable of accommodating and fixing the battery module 1 while cooling air by introducing air is used.

Figure 2 is a cross-sectional view showing a tray assembly for receiving a battery according to the prior art. Among the conventional tray assemblies, the tray assembly shown in FIG. 2 has a relatively preferable structure than other conventional techniques in terms of efficiency of cooling the battery 1a. Referring to FIG. 2, the tray assembly includes a tray 10 in which the battery module 1 is accommodated and fixed, and an outer case 20 in which the tray 10 is embedded.

The tray 10 has a wall plate 12 and a bottom plate 14 and an air inlet plate 16 which is inclined and installed to have an inclined air inlet passage 18 under the bottom plate 14. In addition, an air inlet 15 is formed at one side (the left side in FIG. 2), and the bottom plate 14 is provided at the bottom plate 14 so that air introduced into the air inlet 15 can pass between the battery modules 1. A plurality of vent holes 14a are formed.

In addition, the outer case 20 has a wall 22 and a top plate 24, the top plate 24 is inclined to have an inclined air discharge passage 28, but the air inlet 15 of the tray 10 ), An air outlet 25 is formed on one side (right side in Fig. 2) facing the side 1). In addition, a suction fan (not shown) is installed at a portion where the air outlet 25 is formed.

Therefore, the outside air is introduced through the air inlet 15 by the suction force of the suction fan, and then passes through the air vent 14a to cool between the battery 1a and the battery module 1, and then the air outlet. It is discharged to the outside through (25).

The tray assembly according to the prior art as described above (FIG. 2) has an air inlet passage 18 and an air outlet passage expanded to the air inlet 15 and the air outlet 25 at the same time while holding and fixing a plurality of battery modules (1) The air inlet plate 16 and the upper plate 24 are formed to be inclined so as to have a 28 so that the inlet / outlet of the air is free and the cooling efficiency is good as compared with other conventional techniques.

However, FIG. 2 shows a relatively small number of battery modules 1 housed therein. In particular, in the case of a hybrid electric vehicle, a large number of battery modules 1 are built in, requiring a large amount of power. As such, when a large number of battery modules 1 are accommodated, the length of the tray assembly (left and right directions in FIG. 2) is increased, and thus a large space is occupied when the battery module 1 is embedded in the vehicle body. In addition, as the length increases, the air inflow passage 18 also lengthens, causing the inflow of air not to pass through all of the batteries 1a to be biased to one side and thus not having excellent cooling efficiency.

In addition, the battery 1a and the battery module 1 are connected to many wires such as wires connected to the vehicle body, temperature sensing wires, voltage sensing wires, and current sensing wires connected to the PCB board mounted on the tray assembly. Conventionally, it is not aesthetically ill to provide a separate means for organizing the wires as described above, as well as the aging due to the circumference and external exposure in the process of installing and dismantling the tray assembly to the vehicle body due to the wires are exposed to the outside. Due to this there was also a problem that the wire is broken or bad connection occurs.

The present invention has been invented to solve the above problems, the object is to provide a battery assembly tray assembly having a shorter length by reducing the installation space as possible by stacking the tray in two layers and having excellent cooling efficiency There is this.

In addition, another object of the present invention is to provide a tray assembly for a battery housing that allows the trays to be stacked and assembled in two layers and to arrange the wires at the same time by installing a binding table having a wire insertion groove formed in the tray. .

In order to achieve the above object, the present invention comprises a tray for accommodating a battery module, and an outer case having a wall so that the tray is embedded therein, and the tray is inclined under the bottom plate and the bottom plate having a wall plate, a vent formed therein. In the battery receiving tray assembly consisting of an air inlet plate formed in a shape,

Two trays are stacked inside the outer case, and a tray for fixing the tray to the outer case is installed on a wall plate of the tray, and the binder is formed with a wire insertion groove through which an electric wire can be inserted. A battery housing tray assembly is provided. And, the inner surface of the wall of the outer case may be attached to the base on which the binding table is seated.

The tray assembly according to the present invention has an air inlet passage and an inlet discharge passage to cool the battery, and the air inlet passage and the inlet discharge passage are preferably inclined.

Therefore, in the present invention, by stacking two trays inside the outer case, the length of the outer case is shortened, and the installation space in the vehicle body is reduced as much as possible. At the same time, as the length is shortened, the air inflow passage and the air discharge passage are shortened. Air is allowed to pass through the battery, which is characterized by excellent cooling efficiency. In addition, the tray is provided with a binding stand is assembled to the outer case and at the same time characterized in that the wire can be arranged in order to form a wire insertion groove into which the wire is inserted. In addition, when a pedestal is attached to the outer case, the binding stand of the tray is seated on the pedestal, so that even if a large number of battery modules are accommodated, the weight of the tray can be sufficiently endured, thereby having a structurally strong configuration.
