The contact area of acrylate glue improves adhesive strength.
The installation process of 1 mounting structure of hatch door is illustrated by an embodiment in detail below.
When preparing the body shell 6,6 digital-to-analogue of body shell is first established, at built-in 63 position of plate, vehicle body digital-to-analogue is first
Make corresponding feature.The positional relationship and size requirement of body shell 6 are set, corresponding mould is made, further according to built-in plate 63
Line is pulled on mold in the corresponding position of body shell 6, is made a mark.Then the laying carbon fiber along mold shape from level to level
Dimension/resin prepreg material, then built-in plate 63 and filling matrix 61 are put in a mold in advance, the built-in plate 63 is located at the label of mold
Then place is laid with carbon fiber/resin prepreg material in the outside layer of built-in plate 63 and filling matrix 61, after the 8th layer of braiding
(carbon fiber/resin prepreg material overall thickness is 3.6mm) finally evacuates air bag into vacuum, flexible bag moulding.
Hatch door 1 and reinforcing frame 2 are to be formed using carbon fiber/resin prepreg material through air bag static pressure mode, pass through density work
It skill and is followed by subsequent processing, is formed with the compacting of mold bag.
The both ends of the gas spring are rotatablely connected the first support 52 and the second support 51 respectively.
When assembling first support 52, according to corresponding relationship of the hatch door 1 on body shell 6, described first is adjusted
Position of the frame 52 on the body shell 6, then according to the position of third connecting hole 521 in first support 52 in the vehicle body
It drills on frame 6, bore position passes through the fiber-reinforced resin layer 62 and the built-in plate 63, forms the first connecting hole 631
With the second connecting hole 621, first connecting hole 631 and the second connecting hole 621 finally are passed through with the blind blind rivet of BOM, first
Frame 52 and body shell 6 are riveted together.
When assembling second support 51, first metal connecting plate 82 to process the first pit 821 on one side coarse to be formed
Face, weld bolt 81 pass through and are welded in advance the surface of undressed first pit 821 of metal connecting plate 82, formed on reinforcing frame 2
There is the 5th connecting hole 23, the 4th connecting hole 511 is formed in second support 51, weld bolt 81 is passed through into the 5th connecting hole
23 and the 4th connecting hole 511, directly with acrylate glue and the bonding of reinforcing frame 2, (adhesive thickness is the rough surface of metal connecting plate 82
0.3mm-0.8mm).Reinforcing frame 2 and hatch door 1 are directly bonded by acrylate glue, directly use nut when hatch door 1 finally assembles
The tail end of the 83 fastening weld bolts 81.
When assembling metal baffle 64, metal baffle 64 is done at L-shaped, body shell is directly bonded in by acrylate glue
On 6.
It as shown in figure 11, is 64 adhering method flow chart of metal baffle.
Bonding comprises the concrete steps that: carrying out pre-assembled according to body shell 6 and hatch door 1 first, finds out metal baffle 64 and exist
Position on body shell 6, marks line, marks, and is then surface-treated, and is specially polished with sand paper, sandblasting and solvent
Cleaning prepares acrylate glue, is uniformly coated in 6 mark of body shell, hangs to bonding plane, and the is processed on metal baffle 64
Two pits 641 form rough surface, and 64 rough surface of metal baffle is sticked at scribing position and is overlapped, with the good metal baffle of Boards wall
64, then in the uniform complement point glue of 64 surrounding of metal baffle, extra residue glue is cleared up, after waiting solidifications, clamping plate is unclamped, checks bonding matter
Amount, does up to design requirement is not achieved.
It should be noted that other are in such a way that acrylate glue is bonded with the metal baffle 64 in the present embodiment
Adhering method is similar, repeats no more.
Inventor uses different connection types when carrying out the joint test of body shell 6 and hatch door 1, if not of the same race
The colloid bonding of class, riveting and bolting etc., through a large number of experiments connection type of the discovery using acrylate glue bonding, nothing
Fatigue performance and shearing force performance are better than individual riveting and bolting by being, while also superior to other kinds of glue
Body connection.Specific test is as follows:
Table 1 is that a kind of 1 difference of carbon fiber-reinforced resin class hatch door is fixedly connected with mode fatigue performance test data, wherein
Sample 1# is 1 mounting structure of hatch door provided in this embodiment, and test data shows to be bonded bracket, fatigue performance with acrylate glue
Better than riveting and the connection of bolt attachment bracket and other colloids.
Table 1
Table 2, which is that a kind of carbon fiber-reinforced resin class hatch door 1 is not of the same race, is fixedly connected with mode shearing force performance test data,
Middle sample 1# and sample 2# is 1 mounting structure of hatch door provided in this embodiment, and test data shows to be bonded bracket with acrylate glue,
Shearing force performance is better than riveting and the connection of bolt attachment bracket and other colloids.
Table 2
In conclusion 1 mounting structure of hatch door being bonded using acrylate glue, regardless of still being sheared in terms of fatigue performance
Power aspect of performance all shows good performance.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
