Description
Technical field
The present invention relates to a kind of new-energy electric vehicle pond pallets.
Background technique
Diversification requirement with modern society to energy resource structure, is absorbed in the vehicles of single petrochemical industry driving method
It will necessarily suffer restraints, environmentally friendly, the convenient characteristic of electric energy, so that the vehicles being driven by electricity increasingly match social development
Demand, just because of this, research and development New-energy electric vehicle are the only way which must be passed of development of automobile industry development.The core of electric car
Part includes battery module, it determines the course continuation mileage of electric car in very big one side.Battery tray is in battery module
Play carrying, protection, heat sinking function main component, modular battery pack is disposed in battery tray, passes through battery tray
Disk is fixed on automobile chassis；Battery tray is also responsible for the distributing heat of the task while protecting battery pack, to be battery
Module, which operates normally, provides structural support.
Battery tray is made of aluminium section in the prior art, and aluminium section is first cut into a section discrete portion
Part, then obtain aluminium section for cutting and remove flash removed, then make to obtain one with semiclosed chamber by stirring welding manner
The support holder structure of room after welding, then carries out one of grinding process, leaks hunting finally by leakage tester, thus obtains available
New-energy electric vehicle pond pallet.It will be apparent that the battery tray of the structure is the assembly that discreet component is welded, respectively
There are apparent welding positions between section aluminium section.The battery tray of structure the shortcomings that there is only high production cost, also
Have the shortcomings that structural strength is poor, process consistency is poor.The vibration generated during electric automobile during traveling, is easy to make welding position
Cracked, loosening, causes the disadvantage that structural strength is weak.There is very long duration in welding process, each welding position is simultaneously
Non- same time forming, thus lead to the disadvantage of process consistency difference.
Battery tray is that the assembly that discreet component is welded causes since welding position intensity is low, has welding stress
Such battery tray can not be heat-treated.That is common intensity increases technology, cannot use in such battery tray
On disk.
Summary of the invention
The technical problem to be solved by the present invention is to how improve structural strength and process consistency and reduce production cost,
A kind of new-energy electric vehicle pond pallet is provided thus.
In order to solve the above technical problems, the present invention adopts the following technical scheme: the battery tray includes the ontology casting of aluminum
Part and hot rolled aluminium, the ontology casting are casting integral structure, and the ontology casting is set there are four side wall position and one
Lower portion, the side wall position are located at lower portion edge, and the side wall position is linked together with lower portion, adjacent wall
It is also linked together between position, forms semiclosed chamber between the side wall position and lower portion, the hot rolled aluminium passes through
Stirring welding manner is welded on ontology cast-internal and is located in semiclosed chamber, and the semiclosed chamber passes through hot rolled aluminium point
It is cut into independent installation chamber.
Battery tray in the present invention solves technical problem based on mentality of designing of the cast member in conjunction with weldment.Casting
The ontology casting i.e. main structure for the battery tray that acquisition is, can fully ensure that the structural strength of battery tray entirety in this way.
Hot rolled aluminium surface quality is good, while mechanical property and ductility are stronger, using it as the component for dividing semiclosed chamber
Preferable structural behaviour can be obtained；The welding position quantity generated by the welding of the ontology casting of hot rolled aluminium and battery tray
Considerably less, therefore, the consistency of welding procedure is fully guaranteed.Divided in the technical scheme using hot rolled aluminium semiclosed
Chamber, bring technical effect are not only limited to simplify technique, and also residing in can obtain compared to using monoblock cast acquisition battery
The light-weight advantage that pallet has, because relatively thin hot rolled aluminium can be selected, if dividing half by way of casting
The thickness at the casting position of closed chamber then formed is thicker, otherwise can there is apparent shrinkage porosite phenomenon；In the technical scheme
Can hot rolled aluminium preferred in this way, i.e., the thickness of hot rolled aluminium be less than ontology casting side wall position thickness, the rolling aluminum
The thickness of plate is less than the thickness of the lower portion of ontology casting.In addition to this, casting can form arcuate structure, and aluminium section
It cannot be bent, so, the variations in detail range of the structure of battery tray is wide, can satisfy more design requirements.
The present invention is by adopting the above technical scheme: battery tray main body section is an integral structure, and only generates a small amount of weld part
Position, from improving structural strength, maintaining process consistency, optimized production process has haved the function that reduce production cost, together
When, the main structure of battery tray integral type is more advantageous to heat dissipation.Thus, the protective capability of battery tray, bearing capacity, heat dissipation
Ability all gets a promotion.
Detailed description of the invention
The present invention is further described in detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural schematic diagram of new-energy electric vehicle pond of the invention pallet.
Specific embodiment
As shown in Figure 1, the new-energy electric vehicle pond pallet includes ontology casting 4 and hot rolled aluminium 3.Ontology casting
4 be the casting of aluminium material, and therefore, ontology casting 4 is casting integral structure；Ontology casting 4 is set there are four side wall position 1 and one
A lower portion 2.Side wall position 1 is located at 2 edge of lower portion, and side wall position 1 is linked together with lower portion 2, any side wall
Position 1 is also linked together between side wall position 1 adjacent thereto, and semiclosed chamber is formed between side wall position 1 and lower portion 2
Room.Hot rolled aluminium 3 is also aluminium material, and hot rolled aluminium 3 is welded on ontology cast-internal and positioned at half envelope by stirring welding manner
In closed chamber room, the thickness of hot rolled aluminium 3 is less than the thickness at the side wall position 1 of ontology casting 4, and the thickness of hot rolled aluminium 3 is less than this
The thickness of the lower portion 2 of body casting 4, semiclosed chamber are divided into independent installation chamber, the installation cavity by hot rolled aluminium 3
Room is used to place the battery pack or battery pack of New-energy electric vehicle.The outside of ontology casting 4 is equipped with for connecting with automobile chassis
The connecting portion connect, connecting portion are equipped with through-hole.
Since the main structure of battery tray is cast member, thus there is overall structure, structural strength is significantly larger than welded
The structural strength of component made of connecing, the welding position quantity formed by hot rolled aluminium 3 is few, can guarantee completely in having technique
Its process consistency does not have apparent difference.
