Abstract

A gas discharge structure for a battery cover has a battery cover that covers part or all of a battery, a first hose that is connected with the battery cover at a position of a through-hole provided on the battery cover. and an electric wire that is electrically connected to the battery, is inserted into the first hose, and is drawn out to an outside of a vehicle compartment through an electric-wire lead-out hole provided on a vehicle body panel. A space formed between the electric wire and the first hose communicates with a space inside the battery cover. An end portion of the first hose is located at a position corresponding to the electric-wire lead-out hole, so that an opening of the space formed between the electric wire and the first hose faces the outside of the vehicle compartment.

First claim

The invention claimed is:

1. A gas discharge structure for a battery cover, comprising:
a battery cover that covers part or all of a battery, and that covers a gas release port of the battery;
a first hose that is connected with the battery cover at a position of a through-hole provided on the battery cover; and
an electric wire that is electrically connected to the battery, is inserted into the first hose, and is drawn out to an outside of a vehicle compartment through an electric-wire lead-out hole provided on a vehicle body panel,
wherein a space formed between the electric wire and the first hose communicates with a space inside the battery cover,
wherein the space formed between the electric wire and the first hose is in fluid communication with gas discharge from the battery,
wherein an end portion of the first hose is located at a position corresponding to the electric-wire lead-out hole, so that an opening of the space formed between the electric wire and the first hose faces the outside of the vehicle compartment, and
wherein the space inside the battery cover communicates with the outside of the vehicle compartment via the space formed between the electric wire and the first hose.

2. A gas discharge structure for a battery cover, comprising:
a battery cover that covers part or all of a battery;
a first hose that is connected with the battery cover at a position of a through-hole provided on the battery cover; and
an electric wire that is electrically connected to the battery, is inserted into the first hose, and is drawn out to an outside of a vehicle compartment through an electric-wire lead-out hole provided on a vehicle body panel,
wherein a space formed between the electric wire and the first hose communicates with a space inside the battery cover,
wherein an end portion of the first hose is located at a position corresponding to the electric-wire lead-out hole, so that an opening of the space formed between the electric wire and the first hose faces the outside of the vehicle compartment, and
wherein the battery cover is fixed to a housing of the battery so as to cover a gas release port of the battery.

3. A gas discharge structure for a battery cover, comprising:
a battery cover that covers part or all of a battery;
a first hose that is connected with the battery cover at a position of a through-hole provided on the battery cover; and
an electric wire that is electrically connected to the battery, is inserted into the first hose, and is drawn out to an outside of a vehicle compartment through an electric-wire lead-out hole provided on a vehicle body panel,
wherein a space formed between the electric wire and the first hose communicates with a space inside the battery cover,
wherein an end portion of the first hose is located at a position corresponding to the electric-wire lead-out hole, so that an opening of the space formed between the electric wire and the first hose faces the outside of the vehicle compartment,
wherein the gas discharge structure further comprises:
a plurality of the battery covers; and
a second hose that is connected with the plurality of the battery covers, and

wherein a space inside the second hose communicates with spaces inside the plurality of the battery covers.

4. The gas discharge structure for a battery cover according to claim 1 ,
wherein the electric wire is an electric wire for high voltage.

5. The gas discharge structure for a battery cover according to claim 1 ,
wherein the space formed between the electric wire and the first hose accommodates a fluid-permeable member that is fluid-permeable.

6. The gas discharge structure for a battery cover according to claim 5 ,
wherein the fluid-permeable member is a net-like member.

7. The gas discharge structure for a battery cover according to claim 6 ,
wherein the net-like member that is conductive is integrally mounted on a mounting flange, and the mounting flange is fixed to the battery cover around the through-hole.

8. The gas discharge structure for a battery cover according to claim 7 ,
wherein a connector to be connected with the battery is provided at an end portion of the electric wire and inserted into the through-hole, and
wherein a communication passage that allows an inside of the battery cover and the space to communicate with each other is provided between the connector and the mounting flange.

9. The gas discharge structure for a battery cover according to claim 1 ,
wherein the electric-wire lead-out hole at which the end portion of the first hose is located is provided at a position where negative pressure is generated during a vehicle running.
