Embodiment
The present invention is further described with reference to specific embodiment and attached drawing.
One kind pure electric automobile battery pack mount point structure as described in Fig. 1-Fig. 4, it is fixed that it includes being used for fixing battery pack
Battery installing plate assembly 5 on the longeron or crossbeam 1 of automobile, the battery installing plate assembly 5 are in a groove shape structure, battery peace
Loading board assembly 5 includes two sidepieces 51 that can be positioned on 1 both sides of longeron or crossbeam, can be positioned at 1 upper end of longeron or crossbeam
On the face and bottom 56 between two sidepieces 51, by the top that is formed and be connected with battery pack of raising up among bottom 56
52。
The configuration of the present invention is simple, makes and assembling is easy, and intensity and rigidity are high, disclosure satisfy that the installation of most of battery packs
Reliability requirement, can bear that battery pack weight is larger, in a disguised form add the course continuation mileage of pure electric automobile, generalization degree
Height, welds preferable operability, of low cost.
Wherein, 56 width of bottom of the battery installing plate assembly 5 changes according to the change width of longeron or crossbeam 1.
The top 52 that the bottom 56 raises up is in straight slot shape, and the top 52 of the straight slot shape and two compositions of sidepiece 51 are completed
Bathtub construction.There is vertically arranged reinforcing rib 54 on two sidepieces 51 of battery installing plate assembly 5.And in battery installing plate
The bathtub construction bottom of assembly 5 is respectively equipped with two sidepieces 51, top 52 is corresponding and the installation reinforcing plate of structure in the form of slot
53, running through in the installation reinforcing plate 53 and top 52 has mounting hole 59, and is fixed with and installs in the installation reinforcing plate 53
With the square weld nut 55 of central shaft, battery pack is connected by bolt through mounting hole 59 and the square weld nut 55 in hole 59.
Either reinforcing rib 54, or installation reinforcing plate 53 are for strengthening itself of whole battery installing plate assembly 5
Structural strength and the connection structure intensity between battery pack, to realize the strong fix to battery pack.By combination, by battery
Power suffered by bag mount point position is scattered in the two sides of chassis runner and crossbeam, adds the forced area of mount point position,
Born power is set to be shared by whole vehicle frame while mount point rigidity is met, being less likely to cause local strength's deficiency causes car
The situation of body cracking, while reinforcing rib 54 on the sidepiece 51 of battery installing plate assembly 5 is except that can increase local strength, also has
More fully enter inside cavity beneficial to painting electrophoresis liquid.
In installation reinforcing plate 53 with having also extended through location hole 57 on top 52, which sets side by side with mounting hole 59
Put.In assembling, after being positioned in advance with battery pack by the location hole 57, then square weld nut 55 by mounting hole 59 and thereon leads to
Cross bolt to be connected with battery pack, assembling is simple, and precision is high, convenient operation.
In this example, battery installing plate assembly 5 includes battery installing plate inner panel 501, battery installing plate outside plate 502, wherein,
Battery installing plate inner panel 501 is made of a sidepiece 51, bottom 56, top 52, battery installing plate outside plate 502 by the other side 51,
Bottom 56, top 52 form, which is corresponded to and be stacked and placed on outside battery installing plate by bottom 56, top 52
On the bottom 56 of plate 502, top 52, and form bathtub construction.Pass through battery installing plate inner panel 501 and battery installing plate outside plate
Formed between bottom 56, top 52 between 502 stacked so that the bonding strength between battery installing plate assembly 5 and battery pack
It is further enhanced.
The top 52 of battery installing plate outside plate 502 is equipped with liquid-leaking nozzle 60, in 52 side of top of battery installing plate inner panel 501
Side is equipped with the notch 58 of indent, and the notch 58 is opposite with the sidepiece 51 of battery installing plate outside plate 502 and is communicated with liquid-leaking nozzle 60.
Pass through the setting of liquid-leaking nozzle 60, notch 58 so that total can fully meet painting electrophoresis into leakage requirement so that part is total
Into less easy-to-rust.
Finally, battery installing plate inner panel 501, battery installing plate outside plate 502, installation reinforcing plate 53 are respectively by a monoblock plate
Punch forming, lower cost for material, manufacture craft simple and fast.The battery installing plate inner panel 501, battery installing plate outside plate 502,
Installation 53 spot welding of reinforcing plate is fixed on one.
The technical solution provided above the embodiment of the present invention is described in detail, specific case used herein
The principle and embodiment of the embodiment of the present invention are set forth, the explanation of above example is only applicable to help and understands this
The principle of inventive embodiments；Meanwhile for those of ordinary skill in the art, according to the embodiment of the present invention, in specific embodiment party
There will be changes in formula and application range, in conclusion this specification content should not be construed as limiting the invention.
