Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a heat shield cover for batteries that protects batteries installed in vehicles from hot air. Regarding bars.

0002

[Conventional technology]

Traditionally, it was attached to the battery to protect it from the heat in the engine compartment. As a battery heat shield cover that can be used for (December 1963, published by Nissan Motor Co., Ltd.) on pages B-3 and B-95. What is known is what is known.

0003 This battery heat shield cover is designed to meet the needs of modern engines as they become more powerful and powerful. Due to the increase in the number of equipment installed in the engine room, the heat in the engine room Developed to protect batteries.

0004

[Problem that the idea aims to solve]

By the way, inside the engine room, there are fans that cool the radiator, running air, etc. This creates an airflow, but since the radiator is placed upstream of this airflow, Hot air will circulate inside the engine room.

[0005] Therefore, for example, as shown in FIG. 4, the battery 01 is connected to the strut housing 0. When mounted in the front position of the wall formed in engine room 03 in 2nd class In this case, this battery 01 is placed in the middle of the flow path of the hot air 04 generated as described above. In this case, the hot air 04 may circulate around the battery 01. like this In this case, the entire surface of battery 01 is exposed to hot air, so the battery that covers battery 01 Even if the heat shield cover 05 is set, the temperature of the battery 01 rises and becomes high. There was a fear that the life of the battery 01 would be shortened.

[0006] The present invention was developed with a focus on the above-mentioned problems, and the conventional battery shielding A battery that has a better heat shielding effect than a thermal cover and prevents battery temperature from rising. The purpose of this project is to provide a heat shielding cover that is fully heat shielding.

[0007]

[Means to solve the problem]

The battery heat shield cover of this invention achieves the above purpose by forming a wind guide part and a heat insulating layer. I decided to do so.

[0008] In other words, the battery placed in the middle of the flow path of hot air generated inside the engine room. is provided covering the battery and directs hot air away from the battery to the part facing the hot air flow path. An air guide section is formed that guides the air in the direction of the battery. This means that a heat insulating layer is formed to block the transfer of heat.

[0009]

[Effect]

The hot air hitting the battery heat shield cover is guided by the air guide section and away from the battery. This prevents hot air from circulating around the battery, preventing it from becoming hot. can be prevented.

0010 In addition, hot air is blown into the air guide section of the battery heat shield cover, which can easily become hot. However, by blocking the heat transfer between this air guide and the battery with a heat insulating layer, the battery can become hot. You can prevent it from happening.

[0011]

【Example】

Embodiments of the present invention will be described based on the drawings.

0012 First, the configuration will be explained.

[0013] Figure 2 shows a battery B covered with the battery heat shield cover 1 according to the embodiment of the present invention. FIG. 2 is a plan view showing the engine room 10, with an engine 12 in front of the engine 12; A fan 13 driven by A radiator 11 is provided for cooling water. And in engine room 10 Strut housings 14 are provided on the left and right sides to accommodate struts (not shown). (only the one on the left is shown). The battery B is located behind the fan 13 and on the strut. The position in front of the cut housing 14, that is, in the middle of the flow path of the hot air H from the fan 13. It is located at an angle in the front-rear direction.

[0014] Next, referring to FIG. 1, which is an enlarged view of the main part of FIG. 1 will be explained. That is, the battery heat shield cover 1 is integrally molded from synthetic resin. This battery heat shield cover 1 covers all sides of battery B. A storage section 2 that is slightly larger than the external shape of battery B is shaped to cover the top surface. The terminal 3 of the battery B is exposed to the surface of the battery heat shield cover 1 on the top surface. A terminal hole 4 is formed (see FIG. 3). And this battery heat shield cover 1 The side surface portion facing the flow path of the hot air H has an air guide portion 5 extending toward the rear of the vehicle. A bulged portion 6 is formed. In this bulging part 6, the air guide part 5 and the convergence A space is formed between the container part 2 and a heat insulating layer 7 formed by an air layer in this space. has been completed.

[0015] Further, battery B is fixed to a battery tray 15 attached to the vehicle body. To explain this with reference to Figure 3, battery heat shield cover 1 is attached to battery B. Place the battery B covered with the battery on the battery tray, and then The L-shaped locking part 18a at the lower end of the fixing rod 18 is engaged with the upper end of the fixing rod 18. A bracket that spans the threaded portion 18b formed over the top surface of the battery heat shield cover 1. 16, and a bolt 17 is further tightened to the threaded portion 18b.

[0016] Next, the effect will be explained.

[0017] When the engine is running, the fan 13 rotates as shown in Figures 1 and 2. The hot air H that has passed through the ether 11 flows into the engine room 1 as shown by the arrow in the figure. Flows to 0. This hot air H is blown onto battery B as shown in Figure 1. hits the air guide section 5 of the battery heat shield cover 1 and changes direction to the engine compartment 10. guided behind. Therefore, the hot air H hits the strut housing 14 and moves forward. There is no need to change direction and go around battery B.

[0018] In addition, the air guide section 5 exposed to the hot air H in this way has a heat insulating layer 7 of the air layer, which protects the battery. Since it is insulated from the storage section 2 on the B side, even if the air guide section 5 becomes high temperature, the heat will not be transferred to the back. Transmission to Terry B is prevented.

[0019] As explained above, in the battery heat shield cover 1 of the embodiment, the air guide portion 5 to prevent hot air H from circulating around battery B, and A heat insulating layer 7 made of an air layer is provided between the air guide section 5 exposed to the hot air H and the battery B. This feature prevents the temperature of battery B from rising and reduces the lifespan of battery 2 due to high temperatures. It can prevent shortening of life.

[0020] In addition, since the wind guide section 5 is formed integrally with the battery heat shield cover 1, it can be formed separately. Compared to the conventional structure, it requires less time and effort to form the air guide part 5 and to attach the air guide part 5. It can be omitted.

[0021] Although the above has been explained, the specific configuration is not limited to this embodiment. For example, in the embodiment, a substantially triangular bulge 6 was formed to form the wind guiding portion 5; These shapes may be any other shape as long as they keep the hot air H away from the battery B. Good too. In addition, although the heat insulating layer 7 of the air guide section 5 in the embodiment was formed of an air layer, Even with layers. In addition, the air guide section 5 of the embodiment is integrated with the battery heat shield cover 1. However, it may be a separate type with the air guide section attached later.

[0022]

[Effect of the idea]

As explained above, the battery heat shield cover of the present invention has a hot air flow path. A wind guide part is formed in the part facing the battery to guide hot air away from the battery. Furthermore, a heat insulating layer is formed between the air guide section and the battery to block heat transfer to the battery. This method prevents hot air from circulating around the battery heat shield cover. By using a heat insulating layer to block heat transfer from the wind guide section, which tends to reach high temperatures, to the battery. prevents the battery from getting too hot and shortens battery life due to heat. You can get the effect that you can.
