Description

An integrated framework for chassis batteries of special purpose vehicles

Technical field:

The invention relates to the field of electric vehicles, and mainly relates to an integrated chassis battery structure of a special vehicle.

Background technique:

In the prior art, the power battery pack is fixed on the chassis through some steel structures, and the beams of the chassis are not connected to the beams on the power battery pack, and there is no shared structural framework design with the chassis. Its structural design is unreasonable, and the amount of steel structural parts is large, which increases the weight of the vehicle. At the same time, the layout space of the vehicle is limited, which is inconvenient for the fixed installation, replacement or maintenance of the battery pack. The small space is inconvenient to operate, and the labor intensity Big, time-consuming and labor-intensive.

Invention content:

The purpose of the present invention is to make up for the defects of the prior art, and provide an integrated chassis battery structure of a special vehicle, which shares the beams of the chassis of the special vehicle with the beams on the power battery pack.

The present invention is achieved through the following technical solutions:

An integrated chassis battery structure for a special purpose vehicle, characterized in that it includes a battery box and an upper beam installed between the longitudinal beams of the chassis, the battery box is composed of upper and lower boxes, and the upper box fixed on the integrated beam, the lower box is fixed on the bracket, the bracket with the lower box is fixed on the integrated beam, and the integrated beam with the upper and lower boxes is fixed on On the longitudinal beams on both sides, the upper beam straddles the upper box body and is fixed on the longitudinal beams on both sides.

The upper beam and the integrated beam are fixed at the same position of the longitudinal beam, and the three are fixed together.

The upper beam is fixed on the upper part of the longitudinal beam through connecting angle irons.

The fixing parts are bolts or rivets.

The upper crossbeam is several-shaped, and the integrated crossbeam is one-shaped.

The principle is: the integrated beam of the chassis battery is used for two purposes: one is used as the beam of the power battery to lift the weight of the upper and lower battery modules; the other is used as the beam of the chassis to pull the longitudinal beams on both sides. The lower box bracket of the power battery is connected to the integrated beam through bolts.

The power battery lower box bracket, the upper beam and the longitudinal beam are fixed by bolts; the integrated beam, the upper beam and the longitudinal beam are fixed by bolts; the bracket and the integrated beam are fixed by bolts. The structure between the longitudinal beam, the connecting angle iron and the upper beam: the longitudinal beam and the connecting angle iron are fixed by rivets; the longitudinal beam and the newly added upper beam are fixed by rivets.

The advantages of the present invention are:

The invention has simple structure and reasonable design, and the structural parts of the power battery are shared with the chassis structural parts, which not only reduces the amount of structural parts and the weight of the whole vehicle, but also saves the layout space of the whole vehicle, forming an integrated structure of the chassis power battery.

detailed description:

See attached picture.

An integrated chassis battery structure of a special vehicle, including a battery box installed between the longitudinal beams of the chassis, which consists of upper and lower boxes 6, 10, and an integrated crossbeam 12 is arranged between the upper and lower boxes 6, 10 , the two sides of the lower box 10 are supported by the lower box bracket 11, the upper end of the lower box bracket 11 is connected with the integrated beam 12 through the fixing piece, and the lower box 10 is laid with a 4, the lower chassis 9, the upper box 6 is installed above the lower box 10, and the integrated beam 12 in the upper box 6 is laid with the upper chassis 5 for placing the power battery module, and the upper box 6 is provided with There is an upper beam 3, the upper beam 3 is a several-shaped structure, the lower end of the upper beam 3 is connected with the corresponding integrated beam 12 and the longitudinal beam 1 through the fixing parts, and the two sides of the upper end of the upper beam 3 are fixed on the longitudinal Beam 1 on. The fixing parts are bolts 7 or rivets 8 . The longitudinal beam 1 is a channel structure, and the upper ends of the upper cross beam 3 are respectively installed with connecting angle irons 2 , and are fixed on the longitudinal beam 1 through the connecting angle irons 2 .

Remove the crossbeam on the traditional chassis, add the upper crossbeam 3, the chassis battery integrated crossbeam 12 and the connecting angle iron 2 to form a new crossbeam structure, which has the same function as the original traditional crossbeam (pull the left and right longitudinal beams ). It should be noted in this structure that the newly added upper beam 3 and connecting angle iron 3 are not components of the power battery pack, while the chassis battery integrated beam 12 is also a structural component of the power battery pack, and also serves as a beam of the power battery pack . In the battery pack structure, the integrated beam 12 is subjected to vertical and vertical forces to entrust the battery module. In the chassis structure, it is subjected to left and right lateral forces to pull the longitudinal beams on both sides.

It can be seen from the figure that the components of the power battery pack include the power battery module 4, the upper chassis 5 of the power battery pack, the upper box 6 of the power battery pack, the lower chassis 9 of the power battery pack, and the lower box 10 of the power battery pack. There are 7 structural parts including the lower box bracket 11 of the power battery pack and the integrated beam 12 of the chassis battery.

Said upper beam can be one, two or more.

The bolt connection 8 fixes the integrated beam and the longitudinal beam, the bolt connection 13 fixes the power battery lower box bracket and the longitudinal beam, and the bolt connection 14 fixes the integrated beam and the battery lower box bracket.
