Description
Technical field
The utility model is related to auto parts and components equipment technical field, especially a kind of connection structure of SMC battery box covers.
Background technology
Automotive light weight technology is a general orientation of development of automobile and the important hand of new-energy automobile solution cruising ability at present
Section, huge success is achieved to mould Dai Gang on automotive light weight technology.On new-energy automobile, widely used SMC is compound
Material (Sheet Molding Compound, i.e. sheet molding compound) makes battery box enclosure, other than it can reach loss of weight purpose,
It also has strong protective capability, high antacid fastness, high fire resistance and the protection of excellent anti-electrical isolation.
Current new energy car battery case uses the structure of two-piece unit formula, chassis to be used to bear the weight of entire battery pack
Amount, case lid are buckled in the monnolithic case structure that battery case is constituted on chassis.Sealing ring is set between case lid and the flange on chassis
Or sealing strip is sealed, and achievees the effect that water proof and dust proof.Prefabricated bolt hole, bolt pass through on the flange on case lid and chassis
The flange of case lid is connect with chassis.
Due to SMC battery box covers basis material rigidity preferably and toughness is poor, by the pre- of bolt at link position
Clamp force, in addition Battery case jolts and vibrates in vehicle traveling process, local stress is excessive, and the material of bolt hole position is caused to hold
It is easily cracking and broken, at problem urgently to be resolved.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of connection structure of SMC battery box covers, can effectively solve
The problem of Cracking of certainly existing SMC battery box covers junction in use.
The technical solution of the utility model is：A kind of connection structure of SMC battery box covers, including chassis, case lid, embedding note axis
Set, sealing ring and bolt offer threaded hole, the case lid and embedding note axle sleeve integrated molding, the case lid on the chassis
With it is embedding note axle sleeve integral structure be mounted on chassis on and it is embedding note axle sleeve mesoporous it is corresponding with threaded hole, the case lid with it is embedding
The embedded sealing ring that is equipped with is to seal between noting the integral structure and chassis of axle sleeve, and the bolt is worn in threaded hole and its head
Portion is crimped on embedding note axle sleeve with connecting box lid and bottom disk.
Preferably, the embedding note axle sleeve is metal or nonmetallic high-strength material.
Preferably, integrated molding is realized by gluing or riveting between the case lid and embedding note axle sleeve.
Compared with prior art, the utility model has the advantages that：A kind of SMC batteries provided by the utility model
The connection structure of case lid increases metal or other high-strength materials in cover bolt connection through hole, is integrally formed with product
Or be allowed to be integrally formed with matrix by techniques such as gluing, rivetings, the stress dispersion for allowing SMC matrixes to be subject to reaches material and bears
Range avoids the problem of SMC material cracks.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode, the utility model is described further.
As shown in Figure 1, a kind of connection structure of SMC battery box covers, including chassis 1, case lid 2, embedding note axle sleeve 3, sealing ring 4
With bolt 5.
Specifically：Threaded hole is offered on chassis 1, case lid 2 by gluing or rivets integrated molding with embedding note axle sleeve 3,
Embedding note axle sleeve 3 is metal or nonmetallic high-strength material.
The integral structure of case lid 2 and embedding note axle sleeve 3 is mounted on chassis 1 and the mesoporous and threaded hole phase of embedding note axle sleeve 3
It is corresponding, between case lid 2 and the integral structure and chassis 1 of embedding note axle sleeve 3 the embedded sealing ring 3 that is equipped with to seal, bolt 5 wear into
In threaded hole and its head is crimped on embedding note axle sleeve 3 to connect case lid 2 and chassis 1.
A kind of connection structure of SMC battery box covers provided by the utility model, pre- potting notes axle sleeve at bolt hole position
(metal or other high-strength materials), the curing molding together with case lid, when being bolted case lid and chassis, pre-buried metal is straight
The pressing force for bearing bolt is connect, the stress dispersion for allowing SMC matrixes to be subject to reaches material tolerance range, effectively prevents garage
Battery case jolts and vibrates during sailing, and local stress is excessive, cause the SMC material of bolt hole position be susceptible to cracking and
Broken problem.
The above embodiments are only the preferred embodiment of the utility model, and the right of the utility model cannot be limited with this
Range, therefore, modification made according to the patent scope of the utility model, equivalent variations, improvement etc. still belong to the utility model institute
The range covered.
