PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the
manner in which it is to be performed.

FIELD OF INVENTION
This invention relates to battery support structure assembly for vehicle and more particularly relates to battery tray for vehicles.
BACKGROUND OF INVENTION
For heavy commercial vehicles batteries more than two numbers are mounted on vehicle chassis frame with the help of structural member assembly in a closed or partially closed box made of steel or alternate material.
Commercial vehicle Battery tray or trays are either made of plastic or steel with suitable Battery fluid (acid) resistant coating on it to carry batteries self weight.
For plastic trays used in this case are to be made sufficiently rigid to take care of batteries weight, this is achieved with the help of increased thickness and local ribs and reinforcement which in turn increases the cost of manufacturing and weight of tray.
SUMMERY OF INVENTION
Main object of this invention is to design and integrate a battery tray in such a way that it will not carry any battery load directly.
Another object of this invention is to facilitate battery fluid (acid) flow in case of batteries leakage with the help of vehicle braking acceleration & gravity.
SUMMERY OF INVENTION
According to this invention a battery support structure for vehicles comprising side support members, plurality of base members connected between said side support


members and located above said support members, at least one connecting member to connect the side support member to a long member of said vehicle wherein a battery tray support on said base members and said battery tray having plurality of longitudinal protrusion channels to accommodate said base member

DETAILED DESCRIPTION OF INVENTION
Referring to the figures wherein the showings are the purpose of illustrating a preferred embodiment of the invention only, and not for the purpose of limiting the same.
Referring to the figures 1 to 3, the batteries mounting structure assembly which is made up of side support members (5), vertical side support members (10), spacer brackets/connecting members (2), hat sectioned base members (4), front closing cover (3); mounted on the vehicle chassis frame long member (1) which contains battery tray (6), over spilled battery fluid drain pipe (9), automotive battery assemblies(7) and top cover (8).
The whole assembly is made in such a way that from outside it will look like closed box. The base members (4) are mounted longitudinal to side support members (5) and located above the members. One end of the side support member (5) connected to a vertical support member (10), which in turn is connected to long member (1) of the vehicle using a connecting member (2). The battery tray (6) is formed in such a way that it will overlie with the formations made on battery mounting structure by


base members (4) and is made up of suitable plastic material. The automotive battery assemblies (7) rest on the battery tray, which in turn rests on base members (4) of battery mounting structure assembly.
The battery tray is having side walls located on the four sides. Suitable protrusion channels are made on the tray to accommodate the base members. The protrusion channels are aligned with the direction of travel of vehicle or long member of the vehicle. Referring to figure 3, protrusion channels are located inside the side walls and making a gap (12) between the front and rear side wall in the direction of travel of the vehicle. The gap formed between the end of the protrusion channel and the side wall would allow the free flow of over spilled battery fluid.
In another embodiment of the present invention (refer figure 3) the protrusion channels are running through the rear side wall of the tray thereby making protrusion the side wall (13) to accommodate the base member (4). This particular arrangement will help to accommodate base member having length higher than the length of the tray thereby creating flexibility in assembling. The number of protrusion channels provided should be equal or more than the base members provided to support the tray. During assembly, the battery is placed in the tray and due to protrusion channels on the tray the bottom portion of the battery always in contact with top of the protrusion channels. The base member are located in the protrusion channels and this will help to transfer the battery load directly to the base members there by making the tray a non load bearing member.
The integrated design of battery tray conforming the shape of the structural base members(4)of battery mounting structure assembly, avoids direct loading as well as damages to plastic battery tray(6) surface while loading or unloading of automobile batteries (7).The battery tray(6) as shown in fig.3 has a conduit and drain plug (11) at one of its corner towards the front of the vehicle; the battery tray (6) is assembled in such a way that it will be parallel to the chassis frame long member (1) and will


rest on the base members(4). This arrangement assists in drain of battery fluid (acid) due to inertia effect during braking of the vehicle.
The foregoing description is a specific embodiment of the present invention. It should be appreciated that this embodiment is described for purpose of illustration only, and that numerous alterations and modifications may be practiced by those skilled in the art without departing from the spirit and scope of the invention. It is intended that all such modifications and alterations be included insofar as they come within the scope of the invention as claimed or the equivalents thereof.


WE CLAIM
