Abstract

A mounting structure for an in-vehicle power battery may be provided. The mounting structure may comprise an upper cover ( 3 ), a suspension tray ( 1 ) and a bracket device ( 2 ) for supporting at least a part of a peripheral bottom portion of the suspension tray ( 1 ). The suspension tray ( 1 ) may be hermetically connected with the upper cover ( 3 ), forming a sealed space for receiving the power battery. The bracket device ( 2 ) may be detachably fixed to a bottom surface of the body floor. Further, a vehicle ( 100 ) comprising the mounting structure described above may also be provided.

First claim

What is claimed is:

1. A mounting structure for an in-vehicle power battery, comprising:
a body floor of a vehicle;
an upper cover provided below the body floor, wherein the upper cover is formed with a second joint portion at a peripheral edge thereof;
a support tray hermetically connected to the upper cover, the support tray forming a sealed cavity with the upper cover for receiving the power battery, wherein the support tray is formed with a first joint portion at the peripheral edge thereof;
a bracket device for supporting at least a portion of a peripheral bottom portion of the support tray, wherein the bracket device is detachably fixed to a bottom surface of the body floor;
a supporting beam formed on the bottom surface of the body floor surrounding the upper cover and the support tray, wherein the bracket device is detachably connected to the supporting beam; and
wherein:
the second joint portion is configured to be hermetically and detachably fixed to the first joint portion with an elastic peripheral sealing member being clamped therebetween,
the sealing member includes a flat portion clamped between the first joint portion and the second joint portion and a protuberant portion connected to the flat portion and clamped between the portion of the first joint portion and the supporting beam, and
at least a portion of the first joint portion is configured to be extended under the supporting beam, and an external edge of the sealing member is clamped between the portion of the first joint portion and the supporting beam.

2. The mounting structure of claim 1 , further comprising:
a plurality of water-proof nuts fixed with the first joint portion which are distributed on the first joint portion peripherally; and
a plurality of first bolts, each first bolt being connected to a corresponding water-proof nut for detachably connecting the first joint portion with the second joint portion.

3. The mounting structure of claim 1 , wherein the protuberant portion is formed with an inner chamber.

4. The mounting structure of claim 1 , wherein the bracket device is connected to the supporting beam via coupling of a second bolt with a corresponding nut, and a supporting sleeve is fitted over the second bolt and clamped between the bracket device and the supporting beam.

5. The mounting structure of claim 1 , wherein at least a peripheral rib protruding upwardly is formed on a top surface of the flat portion of the sealing member, which is pressed against the second joint portion.

6. The mounting structure of claim 1 , wherein a peripheral groove is formed on a bottom surface of the flat portion adjacent where the flat portion is joined with the protuberant portion.

7. The mounting structure of claim 6 , wherein the peripheral groove is located where the portion of the first joint portion extended under the supporting beam is joined with the remaining portion of the first joint portion, and the portion of the first joint portion extended under the supporting beam is configured to be lower than the remaining portion of the first joint portion.

8. The mounting structure of claim 2 , further comprising a peripheral pressure plate configured to be located on a top surface of the second joint portion and fixed therewith via the coupling of the first bolts and the water-proof nuts.

9. The mounting structure of claim 1 , wherein the bracket device comprises:
a plurality of main brackets, each of which is connected to the supporting beam via the coupling of the second bolt with the corresponding nut; and
at least an auxiliary bracket which is fixed with the support tray and supports the main brackets respectively.

10. A mounting structure for an in-vehicle power battery, comprising:
a body floor of a vehicle;
an upper cover provided below the body floor;
a support tray hermetically connected to the upper cover, the support tray forming a sealed cavity with the upper cover for receiving the power battery;
a supporting beam formed on the bottom surface of the body floor surrounding the upper cover and the support tray;
a bracket device for supporting at least a portion of a peripheral bottom portion of the support tray, wherein the bracket device is detachably fixed to the supporting beam; and
wherein the support tray is formed with a first joint portion at a peripheral edge thereof; and the upper cover is formed with a second joint portion at a peripheral edge thereof which is detachably fixed with the first joint portion with an elastic peripheral sealing member being clamped therebetween, the sealing member having:
a flat portion clamped between the first joint portion and the second joint portion; and
a protuberant portion connected to the flat portion and clamped between the portion of the first joint portion and the supporting beam; and
wherein at least a portion of the first joint portion is extended under the supporting beam, and an external edge of the sealing member is clamped between the portion of the first joint portion and the supporting beam.

11. A vehicle comprising a mounting structure according to claim 1 .
