By the way, when a battery is provided on the outer surface of the shell of the helmet of Patent Document 1 as in Patent Document 2, the case accommodating the battery is exposed on the outer surface of the shell and is conspicuous as compared with the case where the battery is not provided. , Looks bad from the outside of the helmet.

The present invention has been made in view of the above points, and an object of the present invention is to improve the appearance of the helmet.

In order to achieve the above object, the present invention is characterized in that a battery and a battery case accommodating the battery are provided inside a shell.

Specifically, the first invention is intended for a helmet having a helmet main body whose outer surface is composed of a shell, and has taken the following solving means.

That is, in the first aspect of the invention, an opening is formed in at least one of the lower end surface of the helmet body and the shell, and a lead-out for leading the battery and exhaust gas discharged from the battery inside the shell. A battery unit having a hole and a battery case accommodating the battery is disposed, and the opening of the helmet body and the lead-out hole of the battery case are in communication with each other.

As a result, the battery unit is not exposed on the outer surface of the shell, so that the appearance of the helmet can be improved compared to the case where the battery unit is provided on the outer surface of the shell.

In addition, since the exhaust gas discharged from the battery is released to the outside of the helmet body through the lead-out hole of the battery case and the opening of the helmet body, the exhaust gas stays inside the shell and near the face of the helmet wearer. Can be suppressed from flowing into.

Moreover, since the heat of the battery can be released to the outside of the helmet body through the lead-out hole of the battery case and the opening of the helmet body, the heat of the battery transmitted to the head of the helmet wearer can be reduced.

2nd invention is the helmet of 1st invention, Between the opening part of the said helmet main body, and the derivation|leading-out hole of a battery case, the gas vent passage which guide|induces the exhaust gas led out from the said derivation|leading-out hole to the said opening. Are formed.

As a result, the gas vent passage is interposed between the opening of the helmet body and the lead-out hole of the battery case, so that the opening of the helmet body and the lead-out hole of the battery case can be arranged at positions separated from each other. Therefore, the degree of freedom in arranging the opening of the helmet body and the lead-out hole of the battery case can be increased.

A third aspect of the present invention is the helmet of the first or second aspect, wherein a waterproof ventilation filter regulates entry of water into the battery case in the opening of the helmet body or the lead-out hole of the battery case. It is characterized in that it is arranged as follows.

As a result, the infiltration of water into the battery case is regulated by the waterproof ventilation filter, so that the failure of the battery due to the infiltration of water can be prevented.

A fourth invention is the helmet according to any one of the first to third inventions, characterized in that the opening is formed in the shell.

As a result, it is possible to suppress the high-temperature exhaust gas from hitting the neck of the helmet wearer as compared with the case where the opening is formed in the lower end surface of the helmet body.

A fifth invention is characterized in that, in the helmet of the fourth invention, the opening is formed above the center of the shell in the vertical direction.

As a result, the face of the rear-seat passenger is generally located near the lower part of the shell, and therefore, the hot exhaust gas on the face of the rear-seat passenger is higher than that when an opening is formed in the lower part of the shell. You can suppress the hit.

A sixth invention is the helmet of the second invention, wherein an air inlet is further formed at the front or side of the shell, and between the air inlet of the shell and the gas vent passage, An air passage for guiding the air introduced from the air introduction port to the gas vent passage is formed.

As a result, when traveling with a helmet on a motorcycle or the like, the outside air is guided by the wind from the front to the gas vent passage through the air inlet and the ventilation passage, and joins the exhaust gas flowing through the gas vent passage. The temperature of the exhaust gas discharged from the opening can be lowered.

According to the present invention, the appearance and appearance of the helmet can be improved.
