This application claims priority to and benefits of Chinese Patent Application Serial No. 201120271561.7, filed with the State Intellectual Performance Office of P. R. China on Jul. 29, 2011, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the field of vehicle, more particularly to a mounting structure for an in-vehicle power battery and a vehicle comprising the same.
The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
Commonly, power batteries in an electric vehicle or a hybrid powered vehicle are accommodated in a suspension tray which is provided under a body floor of a vehicle. And normally the peripheral edge of the suspension tray is connected to the body floor, thus the power battery may be mounted under the body floor. However, because the body floor is not sealed, liquid such as water etc. may flow from the body floor to the power battery to bring damage to the power battery accordingly.
However, the in-vehicle power battery may be easily polluted or damaged by water or dust etc, it may reduce the using life or even damage the in-vehicle power battery. Thus, the protection of the in-vehicle power battery is required.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
In viewing thereof, the present invention is directed to solve at least one of the problems existing in the art. Accordingly, a mounting structure of in-vehicle power battery may need to be provided, which may protect the battery against contamination from water or dust etc, and make sure the battery can work normally after a long-term use.
According to an embodiment of the present disclosure, a mounting structure for an in-vehicle power battery may be provided. The mounting structure may comprise an upper cover, a suspension tray and a bracket device for supporting at least a part of a peripheral bottom portion of the suspension tray. The suspension tray may be hermetically connected with the upper cover, forming a sealed space for receiving the power battery. The bracket device may be detachably fixed to a bottom surface of the body floor.
Thus, due to the sealing structure mentioned above, the power battery may not be easily contaminated by water or dust etc., thus extending the life time span of the power battery accordingly.
In one embodiment, a vehicle comprising the above mounting structure is provided.
Other advantages and features of the disclosure are described below.
These and other aspects and advantages of the disclosure will become apparent and more readily appreciated from the following descriptions taken in conjunction with the drawings, in which:
Embodiments of the present disclosure will be described in detail in the following descriptions, examples of which are shown in the accompanying drawings, in which the same or similar elements and elements having same or similar functions are denoted by like reference numerals throughout the descriptions. It is to be understood that, the embodiments described herein are merely used to generally understand the present disclosure, but shall not be construed to limit the present disclosure.
In the following, detailed description of a mounting structure for an in-vehicle power battery will be described, in which like numerals refer to like elements through the accompanying figures.
As shown in
In one embodiment, as shown in
In one embodiment, the supporting beam 9 may be configured to be square, rectangular or other annular shaped form, only if it may surround the suspension tray 1.
In one embodiment, the suspension tray 1 is formed with a first joint portion 101 at a peripheral edge thereof; and the upper cover 3 is formed with a second joint portion 301 at a peripheral edge thereof which is configured to be hermetically and detachably fixed with the first joint portion 101, with an elastic peripheral sealing member 4 being clamped therebetween. During assembly, the peripheral sealing member 4 is tightly compressed between the first joint portion 101 and the second joint portion 301 for sealing purpose. By using the peripheral sealing member 4, such as an annular one, the sealing performance between the upper cover 3 and the suspension tray 1 may be accomplished.
In one embodiment, the mounting structure may further comprise a plurality of water-proof nuts 6 and a plurality of corresponding first bolts 7. The water-proof nuts 6 may be fixed with the first joint portion 101. And as shown in
As shown in
As shown in
In one embodiment, the protuberant portion 402 may be formed with an inner chamber 403, so that the peripheral sealing member 4 may possess enhanced elastic deformation capability and enhance the sealing effects between the protuberant portion 402 and other members. Further, at least a rib protruding upwardly may be formed on an upper surface 4011 of the flat portion 401 in a peripheral direction of the peripheral sealing member 4, which is pressed against the second joint portion 301. As shown in
As shown in
In one embodiment, the mounting structure may further comprise a peripheral pressure plate 8, as shown in
As shown in
From the mounting structure as described above, because all the members or elements are provided under the body floor 10 and tightened thereto, an impact design may be provided accordingly, which is convenient for assembly and maintenance.
As shown in
In one embodiment, the bracket device 2 may comprise four side frames 201 that are connected in series which are fixedly connected with the bottom portion of the suspension tray 1. In addition, the side frames 201 may be detachably connected with the supporting beam 9. The suspension tray 1 and the upper cover 3 are provided inside an area enclosed by the four side frames 201. The side frames 201, the supporting beam 9 and the vehicle floor 10 may form a protective structure to enhance the impact strength of the power battery received in the mounting structure in addition to improved sealing performance. Further, the mounting structure is compact compared with conventional art. In one embodiment, the bracket device 2 may further comprise at least a reinforcing frame (not shown) to improve the suspending strength of the mounting structure.
In one embodiment, as shown in
According to the mounting structure of the present disclosure, the suspension tray 1, the peripheral sealing member 4 and the upper cover 3 may form a sealed structure, and the suspension tray 1, the peripheral sealing member 4, the supporting beam 9 and the body floor 10 may form another sealing structure for the power battery. Through both of the sealing structures, the power battery may be protected from external contamination or damage, such as water or dusts etc.
In the following a vehicle comprising the above mounting structure will be described in detail. As shown in
Although explanatory embodiments have been shown and described, it would be appreciated by those skilled in the art that changes, alternatives, and modifications may be made in the embodiments without departing from spirit and principles of the disclosure. Such changes, alternatives, and modifications all fall into the scope of the claims and their equivalents.
