[0046] The embodiment of the present invention provides a glue connection structure, referring to Figure 1The adhesive connection structure includes two plates and an adhesive layer 3; the two plates are at least partially arranged opposite to each other, each plate includes a first plate surface and a first end side surface, the first plate surface of each plate is a plate surface arranged opposite to the other plate, and the first end side surface of each plate is an end side surface arranged opposite to the other plate; the adhesive layer 3 is connected to the first plate surface of one plate and to the first end side surface of the other plate.

[0047] As an example, the adhesive connection structure includes two panels and an adhesive layer 3. Specifically, the two panels include a first panel 1 and a second panel 2. The first panel 1 and the second panel 2 are at least partially arranged opposite to each other to form two L-shaped bonding positions. Each panel includes a first panel surface and a first end side surface. The first panel surface of each panel is a panel surface arranged opposite to the other panel, and the first end side surface of each panel is an end side surface arranged opposite to the other panel, that is, the normal projection of the first end side surface of the first panel overlaps with the first panel surface of the other panel. Preferably, the first end side surface of each panel can be the normal end side surface of the panel.

[0048] The adhesive layer 3 is connected to the first board surface of one board and to the first end side of another board. In this example, the adhesive layer 3 is connected to the first board surface of the first board 1 and to the first end side of the second board 2. The adhesive layer 3 is connected to the first board surface of the second board 2 and to the first end side of the first board 1. In this way, the connection area between the adhesive layer 3 and the first board 1 and the second board 2 can be expanded, and adhesion can be formed on the first board surface and the first end side (especially the normal end side) of the board, which can disperse the peeling force of the adhesive layer, enhance the peeling strength of the adhesive connection structure, and increase the force direction of the adhesive layer, thereby enhancing the connection strength and reliability between the adhesive layer 3 and the first board 1 and the second board 2 respectively, and reducing the risk of failure.

[0049] In one embodiment, referring to Figure 1 The adhesive layer 3 includes two locking portions; each locking portion is connected to the first plate surface of one plate member and to the first end side surface of another plate member.

[0050] As an example, the adhesive layer 3 includes two locking parts, each of which is connected to the first plate surface of a plate and to the first end side of another plate. Specifically, the two locking parts include a first locking part 32 and a second locking part 33, the first locking part 32 is connected to the first plate surface of the first plate 1 and to the first end side of the second plate 2, and the second locking part 33 is connected to the first plate surface of the second plate 2 and to the first end side of the first plate 1; the connection area between the adhesive layer 3 and the first plate 1 and the second plate 2 can be expanded, and adhesion can be formed on the first plate surface and the first end side (especially the normal end side) of the plate, which can disperse the peeling force of the adhesive layer, enhance the peeling strength of the adhesive connection structure, and increase the force direction of the adhesive layer, thereby enhancing the connection strength and reliability between the adhesive layer 3 and the first plate 1 and the second plate 2, respectively, and reducing the risk of failure.

[0051] In one embodiment, referring to Figure 1 The adhesive layer 3 includes a bonding portion 31; the bonding portion 31 is arranged between the two locking portions; and the bonding portion 31 is connected to the first board surfaces of the two board members.

[0052] As an example, the adhesive layer 3 includes an adhesive portion 31; the adhesive portion 31 is arranged between two locking portions; and the adhesive portion 31 is connected to the first board surface of the two panels. Specifically, one end of the adhesive portion 31 is connected to the first locking portion 32, and the other end of the adhesive portion 31 is connected to the second locking portion 33. One side of the adhesive portion 31 is connected to the first board surface of the first panel 1, and the other side of the adhesive portion 31 is connected to the first board surface of the second panel 2. This arrangement can make the oppositely arranged parts of the first panel 1 and the second panel 2 bonded together through the adhesive portion 31, and at the same time, the adhesive portion 31 is also connected to the first locking portion 32 and the second locking portion 33, further expanding the connection area between the adhesive layer 3 and the first panel 1 and the second panel 2 respectively, which can disperse the force of the oppositely arranged parts of the first panel 1 and the second panel 2, and at the same time increase the force area. When pressure is applied to the first plate 1 and the second plate 2, shear force will be generated. In the direction of the shear force, the adhesive layer 3 and the first plate 1 and the second plate 2 will generate a pulling force to offset part of the shear force, thereby greatly enhancing the shear strength of the adhesive connection structure.

[0053] In one embodiment, referring to Figure 1 Each locking portion is close to the end of the first plate surface of the other plate, extending from the first plate surface of the other plate in a direction perpendicular to the shear force exerted on the other plate; each locking portion is close to the end of the first end side surface of a plate, extending from the first end side surface of a plate in a direction parallel to the shear force exerted on the one plate.

[0054] As an example, the two plates include a first plate 1 and a second plate 2, and the two locking parts include a first locking part 32 and a second locking part 33. The first locking part 32 is close to the end of the first plate surface of the first plate 1, and extends from the first end side of the first plate 1 in a direction parallel to the shear force applied to the first plate 1; the first locking part 32 is close to the end of the first plate surface of the second plate 2, and extends from the first plate surface of the second plate 2 in a direction perpendicular to the shear force applied to the second plate 2; the second locking part 33 is close to the end of the first end side of the second plate 2, and extends from the first end side of the second plate 2 in a direction parallel to the shear force applied to the second plate 2; the second locking part 33 is close to the first end side of the first plate 1 The end of a plate surface extends from the first plate surface of the first plate member 1 in a direction perpendicular to the shear force exerted on the first plate member 1; such a configuration can expand the connection area between the adhesive layer 3 and the first plate member 1 and the second plate member 2, and form a bond between the first plate surface and the first end side surface (especially the normal end side surface) of the plate, which can resist the shear force, disperse the peeling force of the adhesive layer, enhance the peeling strength of the adhesive connection structure, and increase the force direction of the adhesive layer, thereby enhancing the connection strength and reliability between the adhesive layer 3 and the first plate member 1 and the second plate member 2 respectively, and reducing the risk of failure.

[0055] In one embodiment, referring to Figure 1 The thickness of the adhesive layer of the adhesive portion 31 is 0.5 to 2 mm, and the width of the adhesive layer of the adhesive portion 31 is 15 to 30 mm.

[0056] As an example, the thickness of the adhesive layer of the adhesive portion 31 is 0.5 to 2 mm, and the width of the adhesive layer of the adhesive portion 31 is 15 to 30 mm. This arrangement can save costs while meeting the connection strength.

[0057] In one embodiment, referring to Figure 1 The cross section of the locking portion is an arc chamfered structure.

[0058] As an example, the cross-section of the locking portion is an arc chamfered structure, so that the shape of the adhesive layer 3 is an arc structure, which improves the peeling strength, prevents the adhesive layer 3 from cracking, and ensures the connection strength between the first plate 1 and the second plate 2.

[0059] In one embodiment, referring to Figure 1 The arc radius of the arc chamfer structure is 1-2 times the sum of the thickness of the adhesive layer of the bonding portion 31 and the thickness of a plate.

[0060] As an example, the arc radius of the arc chamfered structure is 1-2 times the sum of the thickness of the adhesive layer of the bonding portion 31 and the thickness of the plate where the first end side surface is located. Specifically, the cross section of the first locking portion 32 is a first arc chamfered structure, and its arc radius is 1-2 times the sum of the thickness of the adhesive layer of the bonding portion 31 and the thickness of the first plate 1, which can ensure the connection effect between the first plate 1 and the adhesive layer 3; the cross section of the second locking portion 33 is a second arc chamfered structure, and its arc radius is 1-2 times the sum of the thickness of the adhesive layer of the bonding portion 31 and the thickness of the second plate 2, which can ensure the connection effect between the second plate 2 and the adhesive layer 3.

[0061] In this example, the thickness of the first plate 1 is H1, the thickness of the second plate 2 is H2, the thickness of the adhesive layer of the bonding portion 31 is h, the arc radius of the first arc chamfer structure is R1, and the arc radius of the second arc chamfer structure is R2, R1 = (1~2)*(H1+h); R2 = (1~2)*(H2+h).

[0062] In one embodiment, referring to Figure 1 One plate is a carbon fiber plate, the other plate is a steel plate, and the adhesive layer 3 is a two-component polyurethane structural adhesive.

[0063] As an example, one of the two panels is a carbon fiber panel, and the surface has been roughened by grinding, etc., and the surface energy test dyne value is required to be greater than 40. The other panel is a steel plate, and the surface is electrophoretically coated, and the coating surface energy test dyne value is required to be greater than 40. Adhesive layer 3 is a two-component polyurethane structural adhesive, and the tensile strength of the two-component polyurethane structural adhesive is greater than 10Mpa, and the fracture verification rate is 100% to 200%. This setting can make the connection strength between the two panels stronger, and the adhesive connection structure can increase the shear strength by 30% to 60%, and improve the bonding strength between the carbon fiber parts and the steel plate.

[0064] The embodiment of the present invention provides a glue-spreading and shaping device, referring to Figure 2-5 , including a fixing assembly 4, a push rod assembly 5 and a pressure plate assembly 6; the push rod assembly 5 is installed in the fixing assembly 4, the pressure plate assembly 6 is connected to the push rod assembly 5, and cooperates with two plate parts to make an adhesive layer 3 of the adhesive connection structure.

The fixing component 4 is used as a reference component to place the push rod component 5.

When in use, first apply glue on the partial area where the two plate members are relatively set, and then adjust the position of the pressure plate component 6 through the push rod component 5 by holding the fixing component 4, and then control the pressure plate component 6 to scrape the glue. After the scraping of the glue is completed, the pressure plate component 6 cooperates with the two plate members to shape the glue. In this example, an adhesive layer 3 is formed between the first plate 1 and the second plate 2 by a glue coating and shaping device, and a first locking portion 32 and a second locking portion 33 are formed at the two ends of the adhesive layer 3. The first locking portion 32 is connected to the first plate surface of the first plate 1 and to the first end side of the second plate 2. The second locking portion 33 is connected to the first plate surface of the second plate 2 and to the first end side of the first plate 1. The connection area between the adhesive layer 3 and the first plate 1 and the second plate 2, respectively, can be expanded, and adhesion is formed on the first plate surface and the first end side (especially the normal end side) of the plate, which can disperse the peeling force of the adhesive layer, enhance the peeling strength of the adhesive connection structure, and increase the force direction of the adhesive layer, thereby enhancing the connection strength and reliability between the adhesive layer 3 and the first plate 1 and the second plate 2, respectively, and reducing the risk of failure.
