Description

A kind of battery module structure
Technical field
The utility model is related to batteries of electric automobile module technical field more particularly to a kind of battery module structures.
Background technology
New energy industry is grown rapidly in recent years, and the requirement to power battery and energy-storage battery module is higher and higher, battery The energy density of module, security performance, mechanical strength, the control of cell operating conditions temperature become important in battery PACK industries Problem.The signal of the fixed form in groups of battery, space availability ratio, cell voltage and temperature is adopted in battery modules design process The quality of collection and control as evaluation battery module structure.
Due to the limitation of lithium battery capacity, production technology etc., it is impossible to obtain as lead-acid battery or flow battery that The monomer of sample vast capacity, therefore, the basis of lithium battery scale application is exactly good modular technology in groups.It is electronic at present Automobile uses the battery core of cylindrical type slowly to be approved by market, and also more traditional currently for the modular structure of cylindrical electrical core, It is substantially and is bonded using glue, fixed completely by glue, and the size that the different manufacturer of cylindrical electrical core works it out is not Equally, dimensionally there is several millimeters of deviation, even also being had in the cylindrical electrical core tolerance that same battery core factory works it out Very big deviation, this results in battery core to there is installation gap with module framework, after module integrates, is asked inside PACK there are following Topic:There are gap between battery core and module framework, there is mutually movement, after rocking for a long time, solder joint in operational process with solder joint There are the risks of fatigue fracture.
Utility model content
The utility model provides a kind of battery module structure, simple in structure, and manufacture is at low cost, by using flexible material Material interference fit method fix battery core, avoid the fatigue fracture of the solder joint caused by battery relative motion, and can improve battery core into Group efficiency.
The purpose of this utility model is achieved through the following technical solutions:
A kind of battery module structure, including battery modules frame and in an interference fit mounted on the battery modules Battery core in frame is vertically provided with multiple battery cores on the surface of the battery modules frame and houses cavity, the battery core side by side Accommodating cavity on it lower face inside set one circle battery retainer plate;The battery core includes being arranged on the electric core shell in outside Body, the battery core housing are symmetrically arranged with battery core fixing groove at its position close to upper and lower end face, the battery core fixing groove with Installation is interference fitted between battery retainer plate;Nickel sheet is welded on the positive and negative anodes of the battery core.
Further, the battery modules frame uses double-material injection-molding molding structure.
Further, the battery retainer plate is made of flexible material.
Preferably, the nickel sheet is welded in one piece of cupro-nickel collector plate, and cupro-nickel collector plate is laid on battery modules frame Surface.
Compared with prior art, the utility model at least has the following advantages:
By above-mentioned the technical solution of the utility model, the utility model battery module structure is by battery core, battery modules frame, nickel The compositions such as piece, simple in structure, as a kind of new battery modules fixed structure, battery modules frame uses double-material injection-molding in itself Moulding process, had not only ensured the strength and stiffness of battery modules frame but also to ensure that battery modules frame and battery core are fixed with certain soft Property;It is connected by interference between the battery core fixing groove on the battery retainer plate and battery core on battery modules frame, ensures that battery core has It is fixed on battery core to effect to house in cavity, the mounting means of flexible material interference fit avoids relative motion from causing battery solder joint Fatigue damage;The utility model eliminates the dispensing connection mode of the prior art, the generation of escaping gas is reduced, convenient for reality Existing automated production, realizes the generalization of module parts.
Description of the drawings
Fig. 1 is the self-contained schematic diagram for the battery module structure that the utility model embodiment provides;
Fig. 2 is the structure diagram of battery core in the utility model embodiment.
Specific embodiment
Below in conjunction with the attached drawing in the utility model, the technical solution in the utility model is carried out clearly and completely Description, it is clear that described embodiment is only the part of the embodiment of the utility model, instead of all the embodiments.Base Embodiment in the utility model, the institute that those of ordinary skill in the art are obtained without making creative work There is other embodiment, shall fall within the protection scope of the present invention.
As shown in Figure 1, it is a kind of battery module structure that the utility model embodiment proposes, including battery modules frame 1 The battery core 2 being mounted in an interference fit in battery modules frame 1, it is downward side by side on the surface of battery modules frame 1 It is provided with multiple battery cores and houses cavity 3, the inside that battery core houses the lower face on it of cavity 3 sets a circle battery retainer plate 4.
In specific implementation process, battery modules frame 1 uses double-material injection-molding molding structure.
Further, battery retainer plate 4 is made of flexible material, and electricity is fixed using flexible material interference connection method Core 2 is conducive to avoid the fatigue fracture of the solder joint caused by battery relative motion.
Preferably, the battery core 2 in the present embodiment is 18650 battery cores.
As shown in Fig. 2, battery core 2 includes being arranged on the battery core housing in outside, battery core housing is at it close to the position of upper and lower end face The place of putting is symmetrically arranged with battery core fixing groove 21, and installation is interference fitted between battery core fixing groove 21 and battery retainer plate 4.
Further, nickel sheet is welded on the positive and negative anodes of battery core 2, nickel sheet is welded in one piece of cupro-nickel collector plate, cupro-nickel collection Flowing plate is laid on the surface of battery modules frame 1.
Compared with prior art, the utility model at least has the following advantages:
By above-mentioned the technical solution of the utility model, the utility model battery module structure is by battery core, battery modules frame, nickel The compositions such as piece, simple in structure, as a kind of new battery modules fixed structure, battery modules frame uses double-material injection-molding in itself Moulding process, had not only ensured the strength and stiffness of battery modules frame but also to ensure that battery modules frame and battery core are fixed with certain soft Property;It is connected by interference between the battery core fixing groove on the battery retainer plate and battery core on battery modules frame, ensures that battery core has It is fixed on battery core to effect to house in cavity, the mounting means of flexible material interference fit avoids relative motion from causing battery solder joint Fatigue damage;The utility model eliminates the dispensing connection mode of the prior art, the generation of escaping gas is reduced, convenient for reality Existing automated production, realizes the generalization of module parts.
