providing a recessed second bond on the other of the first mating surface and the second mating surface;
inserting the first bonding part into the second bonding part, and enabling the first matching surface to be attached to the second matching surface, so as to eliminate a reserved adhesive thickness gap between the outer edge of the outer plate and the outer edge of the inner plate;
a bonding glue space is reserved between the first bonding part and the second bonding part;
a plurality of first positioning parts which are further raised on the basis of the first bonding parts are arranged on the first bonding parts at intervals;
a plurality of second positioning parts which are further recessed on the basis of the second bonding parts are arranged on the second bonding parts at intervals;
and inserting the first positioning part into the second positioning part, and enabling at least one surface between the first positioning part and the second positioning part to be attached.
10. The method of designing a resin back door according to claim 9, wherein the cross section of the first bonding portion is a first isosceles trapezoid, the cross section of the second bonding portion is a second isosceles trapezoid, and the length of the long side of the first isosceles trapezoid is equal to the length of the long side of the second isosceles trapezoid;
the length of the short side of the first isosceles trapezoid is X1, and the length of the short side of the second isosceles trapezoid is X2, wherein X1 is less than X2; after the first isosceles trapezoid is inserted into the second isosceles trapezoid, the height distance between the first isosceles trapezoid and the second isosceles trapezoid is X3, and the height of the second isosceles trapezoid is X4, wherein X3 is less than X4; the length of the long sides of the first isosceles trapezoid and the second isosceles trapezoid is X5, the obtuse angle of the first isosceles trapezoid is theta 1, and the obtuse angle of the second isosceles trapezoid is theta 2, and theta 1> theta 2.
11. The method of designing a resin back door according to claim 10, wherein the adhesive force is F Z Adhesive strength sigma, F Z ＝σ*X1+σ*(X5-X1)/cos(180-θ1)*sin(180-θ1)。
12. The method of claim 10, wherein the volume of the paste is V, v= (x2+x5)/2X 4- (x1+x5)/2X (X4-X3).
13. The method of designing a resin back door according to claim 9, wherein the setting of the first positioning portion and the second positioning portion includes a standard direction positioning setting and a molding surface positioning setting;
the standard directional positioning settings further include a Z-directional positioning setting and a Y-directional positioning setting.
14. The method of designing a resin back door according to claim 13, wherein the molding surface positioning setting further comprises:
judging the angle of the molding surface;
when the angle of the modeling surface is smaller than 120 degrees, unidirectional positioning setting is performed;
and when the angle of the modeling surface is more than or equal to 120 degrees, setting the multi-directional positioning.
