Technical Field

The invention relates to a battery, in particular to a modularized battery pack.

Background

Because the lithium battery has the advantages of high specific energy, long service life and the like, more and more electric vehicle manufacturers use the lithium battery as a power source of the electric vehicle. The tab is a carrier for transferring energy between the battery and the outside, and in order to better fix the tab, a tab connecting plate is often adopted to fix the tab in the prior art, and then the tab connecting plate is connected with a circuit board through an electric wire; in addition, the chip set and other connecting parts in the conventional battery pack are matched, and once the chip set determines the number of the chips, other changes are not easy to make, so that the battery capacity cannot be flexibly expanded according to requirements.

Disclosure of Invention

In order to overcome the defects, the invention provides the modular battery pack, the chips are fixed by adopting the fixing supports of the module blocks, so that the number of the chips can be matched according to actual requirements, the lugs in the chips are directly connected with the circuit board and fixed on the supports, a wiring installation method is not adopted, and potential safety hazards such as wire breakage and breakage do not exist.

The technical scheme adopted by the invention for solving the technical problem is as follows:

the utility model provides a modularization group battery, includes a plurality of electric chips, a plurality of mount, circuit board and apron group, electric chip has the up end and the lower terminal surface relative with the up end, be equipped with positive pole, negative pole utmost point ear on the up end, this a plurality of mounts fixed connection in proper order, and press from both sides tight electric chip between two adjacent mounts, electric chip's up end is arranged in to the circuit board, and utmost point ear and circuit board lug direct connection and be fixed in on the mount, the apron group lid in circuit board top and with mount fixed connection.

Preferably, the fixing frames are fixed through clamping, the lug of the electric chip and the circuit board are fixed on the fixing frames through screws, and the cover plate group is fixed on the fixing frames through screws.

Preferably, the fixing frame is a frame structure with a hollow interior and a frame around, one side of the frame is provided with a plurality of buckles, and the other side of the frame is provided with slots for the buckles to be inserted and combined.

Preferably, the inner side of the frame is provided with a partition board, the frame is composed of an upper frame, a lower frame, a left frame and a right frame, two ends of the upper frame protrude upwards to form a bump, and the inner side of the bump is provided with a notch.

Preferably, two first fixed blocks are arranged on the upper frame, a second fixed block matched with the first fixed block is arranged on the inner side of the cover plate group, and the cover plate group is fixed on the fixed frame by locking screws into threaded holes of the first fixed block and the second fixed block.

Preferably, the cover plate group comprises a plurality of large cover plates and a small cover plate, and the small cover plate just covers one fixed frame.

The invention has the beneficial effects that:

1) the battery pack comprises an electric chip, a fixing frame, a circuit board and a cover plate group, wherein the lug of the flexible electric chip is directly connected with the circuit board without using an electric wire, so that the manufacturing cost is reduced, the mounting process is simplified, the safety problem caused by short circuit caused by breakage, aging and the like of the electric wire is avoided because no electric wire is used, and meanwhile, the lug is directly fixed on the fixing frame, so that a lug connecting plate in the traditional process is omitted;

2) the fixing frames are fixed by an inserting method, and the cover plate group is fixed on the fixing frames through screws, so that the mounting and dismounting are very convenient; the fixing frame and the cover plate group are modularized, so that mass production can be performed, the number of the electric chips and the fixing frame is randomly matched according to actual requirements, and the battery capacity with various specifications is combined to meet the diversified requirements of different manufacturers, so that the production cost of a single battery pack is greatly reduced, the traditional battery pack is limited in that the fixing frame is only matched with a chip set for determining the number of the electric chips, and the function is single, so that mass production cannot be performed; in conclusion, the invention can realize large-scale production, has simple integral structure, convenient disassembly and assembly, high anti-seismic performance and good safety performance, and has wide market and application prospect.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
