Refer to Fig. 1, the vehicle back door of the present embodiment, including the door inner panel 2 being oppositely arranged and external door panel 1.External door panel 1
Including installation base plate and honeycomb core 14.Wherein, installation base plate is located at the outside of external door panel, namely the part that can see in Fig. 2.Honeybee
Nest core 14 is located at the inner side of installation base plate, namely installation base plate is near the side of door inner panel 2, and its structure refers to Fig. 3.Described
It is provided with honeycomb core for the rubberised layer 15 gluing with described door inner panel 2, refer to 4.
The vehicle back door of the present embodiment, the setting of honeycomb core 14 and rubberised layer 15 can ensure that and do not increasing vehicle back
On the premise of door weight, increase the structural strength of vehicle back door on the whole, resist deforming and saving raw material of external door panel 1,
So that vehicle back door has preferable mechanical property.
Please with further reference to Fig. 2, external door panel 1 is made up of top outside plate 11 and bottom outside plate 12.Obviously, this kind split type
External door panel 1 structure is easy to machine-shaping, and especially when external door panel 1 using plastic material is, the structure of this kind of external door panel 1 is easy to be molded
Molding.
In the present embodiment, but the material of installation base plate and honeycomb core 14 is preferably necessarily plastics.Wherein, plastic material
Selection can further mitigate the weight of vehicle back door, and so that installation base plate and honeycomb core 14 pass through to be molded into
Type obtains.It should be noted that when the injection mo(u)lding respectively of installation base plate and honeycomb core 14 it is ensured that the outward appearance of installation base plate
Quality, thus meet vehicle back door appearance requirement.And, now preferably adopt the side of bonding between installation base plate and honeycomb core
Formula is fixed.Certainly, it is also possible to by installation base plate and honeycomb core 14 one in the case of not high to vehicle back door outward appearance demand
Molding.
For example, the material of installation base plate and honeycomb core 14 can select PP+EPDM-TD20, and installation base plate and honeycomb core
14 wall thickness is 2.0-2.5mm.
In Fig. 3, the honeycomb lattice of honeycomb core 14 adopt orthohexagonal version.Wherein, orthohexagonal honeycomb lattice tool
There is good geometric mechanics performance, such that it is able to the structural strength of further support vehicles back door.Certainly, the form of honeycomb lattice
It is not limited by the accompanying figures, it can also be any other shape.And, the size of honeycomb lattice can adjust.Especially honeycomb lattice
Height, the thickness of rubberised layer 15 can be changed by the size adjusting its height, thus adjust an inner panel 2 and external door panel 1 it
Between bonding force size.
In the present embodiment, the length of side of preferably honeycomb core 14 is 15-20mm, and the height of honeycomb core 14 is 3-4mm.
On this basis, you can rubberised layer 15 is arranged on the internal layer of external door panel 1, as shown in Figure 4；Can also be by rubberised layer
15 are filled in the honeycomb core 14 of external door panel 1.In wherein Fig. 4, honeycomb core 14 (not shown in Fig. 4) is provided with limit rib
13, this limit rib 13 can be used for limiting the thickness of the rubberised layer 15 being coated on honeycomb core 14.Additionally, when rubberised layer 15 is filled
When in the honeycomb core 14 of external door panel 1, now cost is higher, but bonding is more stable.
The structure of the door inner panel 2 of the present embodiment refers to Fig. 5, is configured with recessed in the side of the close external door panel 1 of door inner panel 2
Groove reinforcement structure, so that door inner panel 2 has stronger bending resistance.And, it is provided with described groove reinforcement structure
Reinforcement 4 plate.
The version of one of which reinforcement 4 plate refers to Fig. 6, and reinforcement 4 plate is along described groove reinforcement structure
Bearing of trend indentation is distributed, thus the groove reinforcement structure in door inner panel 2 is divided into multiple triangle spaces, so that
Door inner panel 2 obtains stable, firm, pressure feature.
And, understand in conjunction with Fig. 7, the surrounding structure of the corresponding vehicle window of door inner panel 2 has above-mentioned groove reinforcement structure it is clear that being somebody's turn to do
Planting structure not only can increase the structural strength of an inner panel 2, can also be easy to the setting of reinforcement 4 plate.
The material of the door inner panel 2 of the present embodiment and its reinforcement 4 plate preferably employs PP-LGF, and wall thickness is 2.0-2.5mm.
Certainly, door inner panel 2 and its reinforcement 4 plate can also adopt other types of plastic material, and can be obtained by injection mo(u)lding
Arrive.
In the present embodiment, it is fixedly connected using gluing between door inner panel 2 and external door panel 1, thus avoiding injection molding deformation, and
And make vehicle back door outward appearance more graceful.
Please with further reference to Fig. 1, the vehicle back door of in figure is also provided at maintenance blanking cover 3, so that it is guaranteed that vehicle back
The dependability of door, the motility of convenient maintenance and technique (as painted) and Element Design (as the design of license plate).Its
In, maintenance blanking cover 3 is arranged on the position being easier to damage.
It is noted that on the premise of ensureing that properties of product are quite even better, tradition is substituted using plastic material
Panel beating material, so that vehicle back door loss of weight 30%, to realize the lightweight of vehicle, and then is reached by vehicle loss of weight and subtracts
The purpose of few oil consumption.Wherein, external door panel 1 loss of weight about 10%, door inner panel 2 loss of weight about 20%.
And, when the material of vehicle back door switches to plastics by metal, the injection that conventional metal cannot be realized can be completed
Processing is integrally formed, and realizes attachments standards；Wherein, Shooting Technique can integrated empennage, antenna, spoiler, license support etc.
Part, reduces number of molds, reduces cost further, and simplifies assemble flow.For example, it is possible to hinge is integrated in an inner panel 2
On；Rear window, car light and spoiler are integrated in external door panel 1.
Additionally, the vehicle back door of plastic material, it can improve the degree of freedom of vehicle back door appearance design, realize difference
Change moulding, make design more aobvious original and different so that door inner panel 2 can realize class-A surfaces, and external door panel 1 can be designed to
Off-line module.
The assemble flow of the vehicle back door of the present embodiment refers to Fig. 8.
Embodiment of above is merely to illustrate this utility model, rather than to restriction of the present utility model.Although with reference to enforcement
Example has been described in detail to this utility model, it will be understood by those within the art that, to technology of the present utility model
Scheme carries out various combinations, modification or equivalent, without departure from the spirit and scope of technical solutions of the utility model, all should
Cover in the middle of right of the present utility model.
