[0002] The main function of a car fuel tank is to store fuel. In addition, it also has the functions of dissipating heat and sinking oil stains. It includes a box body with an opening. The box body of a current car fuel tank is made by welding a cylinder with open ends to end plates at both ends. The high temperature generated during the welding process will cause the box body to form oxide scale, which is very troublesome to remove. On the one hand, it affects the welding quality, and on the other hand, it will also affect the cleanliness of the fuel during use. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a fuel tank for an automobile, wherein the cylinder body and the end plate of the fuel tank are connected by a biting connection structure, thereby reducing oxide scale generated by welding and solving the deficiencies of the prior art.

[0004] The technical solution of the utility model is: an automobile fuel tank, comprising a box body with an opening, the box body comprising a cylinder with two open ends and an end plate fixedly connected to the end thereof, the edge of the end plate and the end of the cylinder having a matching biting edge connection structure, and the end plate and the cylinder are connected by the biting edge connection structure.

[0005] Furthermore, glue is provided at the undercut connection structure.

[0006] Furthermore, a connecting piece is installed at the opening of the box body, and the connecting piece is annular. The opening has a folded edge extending to the outside of the box body, and the folded edge and the outer wall of the box body where the opening is located form an annular groove, and the connecting piece is snapped into the groove.

[0007] Furthermore, a groove cooperating with the connecting piece is provided on the outer wall of the box body where the opening is located, and the bottom of the groove and the folded edge form the clamping groove.

[0008] Furthermore, the connecting piece is bonded to the outer wall of the box body and the folded edge forming the slot.

[0009] By implementing the utility model, the cylinder with two open ends and the end plates at two ends are connected and bonded by biting, which can reduce the oxide scale generated by welding and has good firmness and sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] As shown in the figure: opening 1; cylinder 2; end plate 3; first bending surface 4; first right-angle surface 5; second right-angle surface 6; connecting piece 7; third right-angle surface 8; fourth right-angle surface 9; slot 10; groove 11. DETAILED DESCRIPTION

[0015] Embodiments of the present utility model: Figures 1 to 4 As shown, a fuel tank for an automobile comprises a box body with an opening 1, the box body comprises a cylinder body 2 with open ends and an end plate 3 fixedly connected to the end thereof, the edge of the end plate 3 and the end of the cylinder body 2 have a matching bite edge connection structure, as in the present application, the end of the cylinder body 2 has a first bending surface 4 which is perpendicular to the outer wall of the cylinder body 2 and extends to the outside of the cylinder body 2, the edges of the three end plates have a first right-angle surface 5 and a second right-angle surface 6 which are formed by folding, the first bending surface 4 can be bitten between the second right-angle surface 6 and the end plate 3, in order to make the connection between the two more firm and better sealed, glue is provided between the first bending surface 4 and the second right-angle surface 6, when connecting, the end plate 3 is placed under the cylinder body 2, glue is applied to the back of the first bending surface 4 of the cylinder body 2, the edge of the end plate 3 is folded twice in succession to form the first right-angle surface 5 and the second right-angle surface 6, the first bending surface 4 is bitten and bonded.

[0016] As a preferred embodiment, a connector 7 is installed at the opening 1 of the box body. The traditional connector 7 is fixedly installed at the opening 1 by welding, and is used to connect the cover plate, etc., so that the cover plate can be detachably installed. In order to reduce oxide scale, welding is used as little as possible. The present application has a folded edge extending to the outside of the box body at the opening 1, and the folded edge includes a third right-angled surface 8 perpendicular to the outer wall of the opening 1 and a fourth right-angled surface 9 folded outwardly perpendicular to the third right-angled surface 8. The third right-angled surface 8, the fourth right-angled surface 9 and the outer wall of the box body where the opening 1 is located form an annular groove 10, and the connector 7 is snapped into the groove 10. During installation, the opening 1 is first folded once to form an annular third right-angled surface. Angle surface 8, the connecting member 7 is sleeved outside the third right-angle surface 8, and then folded for a second time to form a fourth right-angle surface 9, and the connecting member 7 is clamped and fixed. To increase the firmness of the connection, first apply glue on one side of the connecting member 7 or the outer wall of the box body around the opening 1, and the connecting member 7 is bonded to the box body when it is sleeved outside the third right-angle surface 8, and then glue is applied to the upper end of the connecting member 7. The fourth right-angle surface 9 formed by folding the third right-angle surface 8 is clamped and bonded to the connecting member 7, and the connecting member 7 is clamped and bonded to the opening 1 to increase the strength of the connection. The opening 1 can be a cleaning port, a refueling port, etc. The connecting member 7 can be a flange with screw holes or studs, which is used for a detachable connection with a cover plate installed at the opening 1.

[0017] As a preferred embodiment, a groove 11 is provided on the outer wall of the box body where the opening 1 is located, and a card slot 10 is formed with the third right-angled surface 8 and the fourth right-angled surface 9 at the bottom of the groove 11.
