Abstract

An apparatus for fastening a pressure vessel of a vehicle is arranged to fix the pressure vessel to a vehicle body, where the pressure vessel includes a cylindrical body, dome-shaped curved portions at both ends of the cylindrical body, and bosses at distal ends of the curved portions. The apparatus is arranged to receive the pressure vessel, and further includes: elastic bodies disposed along circumferences of the curved portions of the pressure vessel to support surfaces of the curved portions and to be disposed on a virtual flat cross section vertically crossing the curved portions along the circumferences of the curved portions to support the curved portions of the pressure vessel in all directions; and a fixed structure having one side connected to the elastic bodies and the other side connected to the vehicle body.

First claim

What is claimed is:

1. An apparatus for fastening a pressure vessel of a vehicle, in which the pressure vessel includes a cylindrical body, dome-shaped curved portions at both ends of the cylindrical body, and bosses at distal ends of the curved portions, and is fixed to a vehicle body, the apparatus comprising:
elastic bodies configured to be disposed along circumferences of the curved portions of the pressure vessel to support surfaces of the curved portions and support the curved portions of the pressure vessel in all directions; and
a fixed structure configured to have one side connected to the elastic bodies and the other side connected to the vehicle body,
wherein each of the elastic bodies is configured to include a fixed part connected to the fixed structure and a support part supporting one of the curved portions, the support part being configured as a support curved surface that connects different surfaces of the fixed part by a curved line, the support curved surface contacting the pressure vessel.

2. The apparatus of claim 1 , wherein the fixed part is configured to have an upper end provided with a horizontal surface which is horizontal to a ground and a side end provided with a vertical surface which is vertical to the ground, the support curved surface connecting an end of the horizontal surface and an end of the vertical surface by the curved line.

3. The apparatus of claim 2 , wherein the vertical surface, the horizontal surface, and the support curved surface of each of the elastic bodies form a closed cross section, and a center of each of the elastic bodies is provided with a void portion which is filled with a foam.

4. The apparatus of claim 1 , wherein the fixed structure includes a band which penetrates through each of the elastic bodies or is coupled with an outer side of each of the elastic bodies, and brackets coupled with the band to be fastened with the vehicle body.

5. The apparatus of claim 1 , wherein each of the elastic bodies is made of a composite material including a high strength fiber, the fiber of the composite material is included in each of the elastic bodies in parallel in a circumferential direction of each of the elastic bodies, and an inner layer and an outer layer of each of the elastic bodies is provided with a multi-directional woven fiber.

6. The apparatus of claim 4 , wherein the band is made of the composite material including a high strength fiber and the fiber of the band is disposed in parallel in the circumferential direction of the band.

7. The apparatus of claim 2 , wherein the fixed structure includes a band which penetrates through each of the elastic bodies or is coupled with an outer side of each of the elastic bodies, and
the horizontal surface of each of the elastic bodies is disposed in a length direction of the pressure vessel, the vertical surface thereof is disposed in the radial direction of the pressure vessel, and an inner side of the band is coupled with the horizontal surface of each of the elastic bodies to support the pressure vessel.

8. The apparatus of claim 4 , further comprising:
a dovetail-shaped mounting rail configured to be provided at the vehicle body and provided with grooves at a uniform interval,
wherein one side of the mounting rail provided with grooves is coupled with the brackets and the other side thereof is coupled with the vehicle body.

9. The apparatus of claim 2 , wherein the fixed structure is provided with a band configured to penetrate through each of the elastic bodies or be coupled with an outer side of the elastic body to fasten the plurality of elastic bodies and the horizontal surface of the elastic body is provided with a seating groove in which the band is seated and the seating groove is configured of a lower surface portion which faces-contact the inner side of the band and a side portion which contacts the side of the band.

10. A pressure vessel fastening system of a vehicle, comprising:
a pressure vessel configured to include a cylindrical body, dome-shaped curved portions at both ends of the cylindrical body, and bosses at distal ends of the curved portions;
elastic bodies configured to be disposed along circumferences of the curved portions of the pressure vessel to support surfaces of the curved portions and support the curved portions of the pressure vessel in all directions; and
a fixed structure configured to have one side connected to the elastic bodies and the other side connected to the vehicle body,
wherein each of the elastic bodies is configured to include a fixed part connected to the fixed structure and a support part supporting one of the curved portions, the support part being configured as a support curved surface that connects different surfaces of the fixed part by a curved line, the support curved surface contacting the pressure vessel.
