Technical solution provided by the invention is further detailed below according to specific embodiment.
In an embodiment of the invention, it is poured as illustrated in fig. 1, it is preferred that being provided on upper mold 2 into die cavity
The casting channel 21 for infusing material, mould material is specifically the casting channel being arranged on the upper mold 2 in the die cavity
21 mould materials.
Preferably, which is connected to the location roughly halfway up of 1 bottom plate of support holder structure main body, and preferred vertical
In the bottom plate, mould material can be made to flow to surrounding in this way, each portion in die cavity is quickly flowed to conducive to moulding material
Position.Of course, it should be appreciated that casting channel 21 also can be set at other positions, such as the casting channel 21 by
Support holder structure main body is collectively formed with upper mold, or casting channel 21 is arranged in support holder structure main body, is then forming
After again by the casting channel enclosed in support holder structure main body.
In a preferred embodiment of the invention, it is poured in the die cavity that support holder structure main body 1 is cooperatively formed with upper mold 2
Material be foamed material, molding insulating layer 3 is to be sent out in the die cavity by foamed material on 1 inner surface of support holder structure main body
Steep molding foaming layer.
Wherein, the foamed material, also referred to as foaming agent, bubble can be generated in substance internal gasifier by, which referring to, makes porous
The substance of the foaming of substance, such as manufacture foamed plastics, foam rubber, foamed resin.Foamed material is injected from casting channel
Into the die cavity between support holder structure main body 1 and upper mold 2, after foam material natural foaming pending, it is molded over support holder structure main body 1
Between upper mold 2, foaming layer can be obtained on 1 inner surface of support holder structure main body by then separating upper mold 2.
It will be appreciated by persons skilled in the art that the insulating layer 3 on 1 inner surface of support holder structure main body is not limited to foam
Material is formed by foaming, for example, other rubber or resin material etc. can also be poured into die cavity, as long as support can be molded over
1 inner surface of dish structure main body and the material that plays insulating effect and support holder structure main body 2 can be sealed.
And since foamed material light weight, cushion performance are good, and form and be easy, therefore, which preferably passes through hair
Foam material foaming.The preferred hard foam of the foamed material used in technical solution provided by the invention, in this way can be with
The rigidity and support strength of pallet are effectively improved, while can preferably reduce the weight of pallet entirety again.
In addition, the pallet in present embodiment is set as being suitable for support battery pack, to make the pallet facilitate hookup wire
The structures such as beam, liquid cooling water pipe can have liquid cooling groove 31, wire casing (figure by straight forming on the insulating layer 3 as shown in Figures 2 and 3
In do not show) and structures such as separation convex ribs 32 for the accommodation space of pallet to be divided into multiple portions.Hold battery pack
Pallet be usually arranged as square structure, on the insulating layer 3 setting separate convex ribs 32 can be by the inner volume of square structure point
The multiple compartments for being suitble to the battery in a row arranged in column are divided into, the size of specific compartment can be set according to the battery to be arranged
Meter.Liquid cooling groove 31 and wire casing are set on the insulating layer 3, can directly be arranged cooling liquid cooling pipeline is carried out to battery pack
It is directly arranged in wire casing in liquid cooling groove 31, and by the harness for being used for battery pack.In this way without specially being set in pallet
It sets for facilitating the components such as liquid cooling pipeline and other harness cablings, greatly reduces design cost and period.
Due to being usually provided with other structures such as reinforcing rib, insulation in the accommodation space of support holder structure main body 1
Layer covers that the structures such as reinforcing rib are more difficult by the way of gluing, between the structures such as insulating layer and reinforcing rib at least being pasted
There are gap, the present invention can directly form the insulating layer of covering by the way of moulding by casting on reinforcing rib, casting it is exhausted
The structures such as edge layer and reinforcing rib are tightly combined, and molding is preferable.Wherein the specific constructive form of insulating layer 3 to be formed can lead to
The structure of design upper mold is crossed to realize.
Normally, support holder structure main body 1 includes bottom plate 11 and the side plate 12 around bottom plate 11, can limit use in this way
In the accommodation space for accommodating object (such as battery pack).Cavity design between support holder structure main body 1 and upper mold 2 is so that absolutely
Edge layer 3 can be distributed on the inner surface of the bottom plate 11 and the side plate 12, as shown in Figure 3 and Figure 4.
According to another aspect of the present invention, a kind of pallet is also provided, which includes the pallet knot for being formed with accommodation space
Structure main body 1, directly moulding by casting has insulating layer 3 on the inner surface of the support holder structure main body 1.
Pallet provided by the invention, by be poured directly in support holder structure main body 1 formed insulating layer 3, the insulating layer 3 with
Support holder structure main body 1 is tightly combined, and can effectively promote the performances such as the heat preservation, sealing, buffering of pallet, and enhance pallet
The rigidity of structure and support strength.In addition, the insulating layer 3 has the flaws such as subtle gap, pit in support holder structure main body 1
Position filled, improve the quality of product.
In the preferred embodiment of pallet provided by the invention, which is that foamed material foams the foaming to be formed
Layer.Foaming layer has the characteristics that light weight, cushion performance and good heat insulating.Certainly, which may be by pouring
Infuse the rubber layer or resin layer of the formation such as liquid rubber or resin.
As shown in figs 2-4, which includes bottom plate 11 and the side plate 12 around the bottom plate 11, preferably
Ground, the insulating layer 3 are distributed on the inner surface of the bottom plate 11 and the side plate 12.
In one embodiment, liquid cooling groove 31, wire casing and the receiving sky by pallet are formed on the insulating layer 3
Between be divided into the separation convex ribs 32 of multiple portions.The pallet for accommodate battery pack when, the separation convex ribs 32 by battery pack into
Row separates, and carries out cooling cooling line to battery pack and can directly arrange to be arranged in liquid cooling groove 31, and will be electric
The harness of pond group is arranged in wire casing.In this way without being specially arranged in pallet for facilitating liquid cooling pipe and other harness cablings
Deng components.
In one embodiment, the structures such as reinforcing rib, insulating layer are additionally provided in 1 internal chamber of support holder structure main body
3 are set as being covered in the structures such as the reinforcing rib.
In accordance with a further aspect of the present invention, a kind of battery pack is also provided, which includes pallet and be located on the pallet
Battery pack, wherein the pallet uses that pallet production method as described above is made or the pallet is pallet as above.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited thereto.At this
, can be with various simple variants of the technical solution of the present invention are made in the range of the technology design of invention, including each particular technique
Feature is combined in any suitable manner.In order to avoid unnecessary repetition, the present invention is to various combinations of possible ways
No further explanation will be given.But it should also be regarded as the disclosure of the present invention for these simple variants and combination, belongs to the present invention
Protection scope.
