Abstract

(57) [Abstract] [Purpose] The present invention is a heat shield case in which a rib is provided on the inner wall surface of a storage case for storing a storage battery. Elastic ribs are provided at predetermined intervals between the storage battery and the case. By forming voids, it is possible to facilitate excellent heat insulation effect and battery replacement work. [Structure] The present invention is provided with a feather rib having a V-shaped cross section along the height direction of the inner wall surface of the storage battery storage case.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a heat shield case for accommodating a lead storage battery and insulating it from the outside air.

[0002]

[Prior Art]

 Conventionally, when a lead storage battery is installed in an automobile or the like and the automobile is operated, the storage battery is heated by heat generated from the engine of the automobile, which causes deterioration of the storage battery and shortens its life. .

Therefore, in order to prevent the temperature rise of the storage battery, the following heat shield case is provided outside the storage battery. That is, as shown in FIGS. 1 and 2, a plurality of polypropylene-equipped ribs 3 and 3'are integrally fixed to the inner wall surface of a polypropylene-equipped box-shaped storage case 2 at desired intervals along the height direction thereof. The heat shield case 1 is provided, and the storage battery 4 is housed in the heat shield case 1. By providing the ribs 3 and 3 ', the storage battery 4 is supported and a space is formed between the storage battery 4 and the storage case 2 to prevent the storage battery 4 from being heated. However, since the ribs 3 and 3'are rigid and not elastic, the battery case of the storage battery 4 expands due to repeated charging / discharging for a long time in the storage battery, especially in a sealed storage battery, and presses the ribs 3 and 3 '. And firmly adhere. Thus, in converting the storage battery, the storage battery was not taken out from the heat shield case, and the heat shield case had to be replaced together.

[0004]

[Problems to be solved by the device]

 In the present invention, the rib has elasticity, and the storage battery expands or contracts, but this is always followed to take out the storage battery housed in the heat shield case or store the storage battery in the heat shield case. We have developed a heat shield case for storage batteries that can be easily replaced.

[0005]

[Means for Solving the Problems]

 The present invention is characterized in that a plurality of elastic heat-insulating feather ribs are fixed to the inner wall surface of the storage battery storage case along the height direction so as to have a V-shaped cross section.

[0006]

[Action]

 Since the rib according to the present invention has a V-shaped cross-section, when the storage battery expands and presses the rib as described above, the rib has elasticity and the tips thereof are simultaneously pressed so that the rib is easily closed. The rib and the storage battery are brought into close contact with each other with a pressure such that they are always in contact with each other. Therefore, in the operation of replacing the storage battery housed in the heat shield case, the storage battery can be easily taken out and only the storage battery can be replaced.

Further, since the ribs are attached along the inner wall surface of the storage case at desired intervals, when the storage battery is stored in the case, a gap is formed between the storage battery and the case. It is made to enhance the heat shield effect.

Further, the ribs are formed in a V-shape in cross section, and one of the ribs is formed so that the tip end thereof is tapered so that the rib can be slidably stored when the storage battery is stored in the storage case. Therefore, the workability is facilitated. The angle of inclination of both rib pieces is not limited to this, but is usually preferably 25 ° to 35 °.

Further, the ribs are preferably attached at their lower ends in contact with the bottom surface of the storage case and along the height direction so that the stored storage batteries can be firmly fixed.

[0010]

EXAMPLE As shown in FIG. 3, a polypropylene type box-shaped storage case 12 has an inner wall surface having a C-shaped cross section as shown in FIG. 4 and a tip end portion inclined as shown in FIG. A heat shield case 11 for a storage battery according to the present invention was obtained by fixing a 5 cm-sized feather rib 13 (angle 30 °) with its lower end in contact with the bottom of the case at a predetermined interval along the height direction of the case.

[0011]

[Effect of the device]

 According to the present invention, since the rib has elasticity and the storage battery expands due to heat and presses against the rib, the rib follows the force and the rib bends toward the wall surface of the heat shield case. It is always held with a constant joining force between and. Therefore, when replacing the storage battery, it can be easily removed from the heat shield case, and the heat shield case can be used repeatedly. Further, it is industrially useful, for example, a storage battery can be stored in the heat shield case without rattling.
