Abstract
The utility model discloses a kind of new-energy electric vehicle pond pallets, it includes the ontology casting and hot rolled aluminium of aluminum, and ontology casting is an integral structure, and hot rolled aluminium is welded on ontology casting.Battery tray main body section is an integral structure, and only generates a small amount of welding position, from improving structural strength, maintain process consistency, optimized production process, have the function that reduce production cost, meanwhile, the main structure of battery tray integral type is more advantageous to heat dissipation.Thus, protective capability, bearing capacity, the heat-sinking capability of battery tray all get a promotion.
Description
Technical field
The utility model 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 problems to be solved in the utility model is how to improve structural strength and process consistency and reduce to be produced into
This, provides a kind of new-energy electric vehicle pond pallet thus.
In order to solve the above technical problems, the utility model adopts the following technical solution：The battery tray includes the sheet of aluminum
Body casting and hot rolled aluminium, the ontology casting are casting integral structure, the ontology casting 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
Side wall is also linked together between position, and semiclosed chamber, the hot rolled aluminium are formed between the side wall position and lower portion
Ontology cast-internal is welded on by stirring welding manner and is located in semiclosed chamber, and the semiclosed chamber passes through rolling aluminum
Plate is divided into independent installation chamber.
Battery tray in the utility model solves technical problem based on mentality of designing of the cast member in conjunction with weldment.
Casting obtains the ontology casting i.e. main structure for the battery tray for being, can fully ensure that the structure of battery tray entirety is strong in this way
Degree.Hot rolled aluminium surface quality is good, while mechanical property and ductility are stronger, using it as the portion for dividing semiclosed chamber
Part can obtain preferable structural behaviour；The weld part digit generated by the welding of the ontology casting of hot rolled aluminium and battery tray
Measure considerably less, therefore, the consistency of welding procedure is fully guaranteed.It is sealed in the technical scheme using hot rolled aluminium segmentation half
Closed chamber room, bring technical effect are not only limited to simplify technique, and also residing in can obtain compared to using monoblock cast acquisition electricity
The light-weight advantage that pond pallet has, because relatively thin hot rolled aluminium can be selected, if divided by way of casting
The thickness at the casting position of semiclosed chamber then formed is thicker, otherwise can there is apparent shrinkage porosite phenomenon；In the technical program
In 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 hot rolling
The thickness of aluminium sheet is less than the thickness of the lower portion of ontology casting.In addition to this, casting can form arcuate structure, and aluminum type
Material cannot be bent, so, the variations in detail range of the structure of battery tray is wide, can satisfy more design requirements.
The utility model is by adopting the above technical scheme:Battery tray main body section is an integral structure, and only generates a small amount of weldering
Socket part position, from improving structural strength, maintaining process consistency, optimized production process has reached the work for reducing production cost
With, meanwhile, the main structure of battery tray integral type is more advantageous to heat dissipation.Thus, the protective capability of battery tray, carrying energy
Power, heat-sinking capability all get a promotion.
Detailed description of the invention
The utility model 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 pallet of the utility model.
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.
