The gas container 2 inserted into the storage space 33 can be adjacent to the gas container 2 in the first diaphragm portion adjacent to the gas container 2 in the plurality of first diaphragm portions 31 and the plurality of second diaphragm portions 32. The second diaphragm portion is in contact with support. Therefore, even when traveling, the flow of the gas container 2 can also be minimized.
[0033]These partition wall portions 3 can be disposed in the front housing portion 13 and the rear housing portion 14, respectively. Specifically, the partition wall portion 3 disposed in the front housing portion 13 may be a front partition wall portion 3a, and the partition wall portion 3 disposed in the rear housing portion 14 may be a rear partial wall portion 3b. In order to connect the gas container 2 accommodated in the interior space of the housing 1 to be disposed outside the housing 1, one side of the housing 1 may include a tube portion 4 connected to the gas container 2. Valve 5.
[0034]referencefigure 2 withFigure 5 The multi-valve 5 can be disposed outside the housing 1. Specifically, the multi-valve 5 can be disposed from the rear side portion of the lower casing 12. The position of the multi-valve 5 can be changed as needed. In other words, the multi-valve 5 may be disposed anywhere in the housing 1, whether it is the upper side, the lower side, and the side, and the like.
[0035]The multi-valve 5 can be configured to include: the first valve 51, the first valve discharges the gas fuel stored in the gas container 2 to the engine; the second valve 52, the second valve will supply gas supplied from the outer portion of the housing 1 Fuel introduces gas container 2; and port 53, which is coupled to the multi-tube 44 of the tube portion 4. In other words, the multi-valve 5 can be configured to include a first valve 51 which can be connected to the engine, a second valve 52 which can be connected to an external gas supply device, and a port 53 which can be coupled to the gas container 2.

The rear tube portion 42 can realize gas transmission between the tube connection portion 21b. The rear tube portion 42 can be coupled to the intermediate tube 43 to enable gas transmission between the rear tube portion 42 and the intermediate tube 43.
[0040]referenceFigure 4 After the rear gas container 2b can be arranged in the rear housing portion 14. Further, the rear tube portion 42 can be configured to be rear tube 421 for connection between a series of gas containers arranged in the front and rear direction in the rear gas container 2b. Specifically, the rear tube 421 can be coupled between the tube connection portion 21b of the rear gas container 2b. The rear gas container 2b can be attached to a gas container disposed on a straight line in front-rear direction via a rear tube 421. The rear tube 421 can be connected to the tube connection portion 21b and the intermediate tube 43.
[0041]The intermediate tube 43 can be disposed in the intermediate housing portion 15 and can be coupled to the front tube portion 41 and the rear tube portion 42. Further, the intermediate tube 43 can be coupled to the multi-tube 44. Further, the multi-tube 44 can be coupled to the port 53 of the multi-valve 5. In other words, the multi-tube 44 can be disposed between the intermediate tube 43 and the multi-valve 5 to be connected to the port 53 and the intermediate tube 43 of the multi-valve 5.
[0042]In the gas fuel storage device as described above, since the housing 1 can be mounted on the lower side of the body 6, the gas storage capacity can be easily ensured than the existing gas container, the internal space of the body 6 does not need to be set. The support body of the existing large gas container is mounted, and the internal space and trunk of the vehicle can be prevented from being reduced due to the housing 1, and therefore, the internal contained inner contained in the vehicle can be prevented from deteriorating.
[0043]Further, the gas fuel storage device can utilize the existing battery housing for the electric vehicle without re-designing the housing 1, and thus can reduce the investment cost. For example, the battery power terminal is typically mounted at the rear side of the battery housing. Therefore, the multi-valve 5 can be mounted on the rear side of the battery housing mounted with a power supply terminal without having to modify the battery housing separately. Further, with the case of using a small size of the gas container 2, the gas fuel storage device has an advantage of the gas container having the gas container with the existing gas container 2.
[0044]Although exemplary embodiments of the present disclosure are described in detail above, the scope of the present disclosure is not limited thereto, but may include several of the present disclosure of the present disclosure by the claims by those skilled in the art. Modify and change.
