Description

Electric motor car branch case

Technical Field

The utility model relates to an electric motor car branch case.

Background

Along with the further improvement of the living standard of people, the electric vehicle hopes to have one vehicle of the people, is favored by users because of energy conservation, environmental protection and the like, and has the advantages of large and heavy lead-acid battery, short cycle life and environmental protection. The lithium battery is taken as a new energy source, has large energy density and long endurance, and is environment-friendly. At present, most common electric vehicle batteries are installed in an integrated mode, the size is large, the electric vehicle batteries cannot be compatible with the original assembly mode of lead-acid batteries, installation or modification difficulty exists in the installation and modification process, time and labor are consumed, and popularization of lithium batteries is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the prior art problem, and the design of a branch case that provides solves electric motor car installation difficulty, and the equipment is convenient, and the cluster is nimble.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an electric motor car branch case, includes No. one first case, No. two cases and No. three cases, No. one first case, No. two cases, No. three cases loop through the thread and adopt the terminal to connect, No. one first case left end is provided with total positive terminal, No. three case right-hand member is provided with total negative terminal, No. one first case, No. two cases and No. three incasement all are provided with the lithium cell.

Preferably, installation and maintenance ports are formed in the first box, the second box and the third box.

Preferably, the first box, the second box and the third box are all provided with handles.

Compared with the prior art, the utility model has the advantages of: the utility model discloses set up first case, No. two cases and No. three cases, the mode of branch case design can directly be through cushion assembled battery, does not need the whole car of raising on the present market to trade the electric mode, and the assembly is simple, and is nimble. The utility model discloses put the lithium cell at the battery box of difference on average, No. first case left end is provided with total positive terminal, No. third case right-hand member is provided with total negative terminal. In the mode, the left side is always positive, and the right side is always negative, so that the wiring harness can be ensured not to be disordered.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a top view of the present invention.

In the figure: first case 1, second case 2, third case 3, total positive terminal 4, total negative terminal 5.

Detailed Description

The technical solutions in the embodiments will be described clearly and completely with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments, but not all embodiments.

Referring to fig. 1-2, an electric vehicle branch box comprises a first box 1, a second box 2 and a third box 3, a battery can be assembled directly through a cushion in a branch box design mode, and the electric vehicle branch box does not need to be lifted up and replaced on the market. And the first box 1, the second box 2 and the third box 3 are connected through a main line terminal in sequence. No. 1 left end of first case is provided with total positive terminal 4, No. 3 right-hand members of third case are provided with total negative terminal 5, and total positive terminal 4 and total negative terminal 5 adopt the aviation plug, guarantee the reliability of product. All be provided with the lithium cell in No. 1 case, No. 2 case and No. 3 case, lithium electricity energy density is big, and the size that is littleer than the lead acid can reach lead acid capacity, and the reliability is high, can overcurrent, all be provided with the installation maintenance mouth on No. 1 case, No. 2 case and No. 3 case. When the collecting device is used, the pressure difference can be compensated by connecting different battery bins in front through software, so that the collecting accuracy is realized. All be provided with handle 6 on No. one case, No. two case and No. three case.

Put the lithium cell on average in the battery box of difference, the main control board is placed in No. 1 incasement, and No. 1 case is responsible for the realization of major function, No. 2 transitional action of second case, and No. 3 final third cases are responsible for the collection of electric current, and this kind of mode can guarantee that the pencil can not be chaotic, and the left side is always positive, and the right is always negative.

The above descriptions are only preferred embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the scope of the present invention, and the technical solutions and the utility model concepts of the present invention are equivalent to, replaced or changed.
