Description

Technical Field

[0001] The utility model relates to the technical field of high-end equipment manufacturing devices, and particularly relates to a support column in an automobile fuel tank. Background Art

[0002] A plug-in hybrid electric vehicle (PHEV) is a new energy vehicle between a pure electric vehicle and a fuel vehicle. It has both the engine, transmission, drive system, and fuel tank of a traditional vehicle, as well as the battery, motor, and control circuit of a pure electric vehicle. It can achieve pure electric and zero-emission driving, and can also increase the vehicle's cruising range through the hybrid mode. Compared with the fuel tank of a traditional fuel vehicle, the fuel tank volume of a PHEV model is reduced, but the related components of the fuel tank fuel supply system have not decreased. Implementing the fuel supply, breathing / venting functions in a smaller space will inevitably lead to an increase in internal pressure. Therefore, columns must be used inside the fuel tank of a PHEV model to avoid deformation.

[0003] The column in the built-in fuel tank of a PHEV model is made of a material with relatively high structural strength, generally a columnar support, and uses a rubber coating process. In the prior art, the parts at both ends for connecting to the inner wall of the fuel tank are usually injection molded onto the middle support column. Since the injection temperature at both ends is higher than the softening temperature of the middle support column, the support column at the contact part will be locally softened during the injection molding process, resulting in pores or penetrations, weakening the structural strength of the coated part at that place, affecting the support effect of the column, and easily causing the fuel tank to deform. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defects in the prior art, provide a fuel tank support column, enhance the structural strength at the connection between the two ends and the middle of the support column, improve the support effect of the support column, and avoid the deformation of the fuel tank.

Detailed implementation mode

[0023] As Figures 1 to 4 shown, a fuel tank support column includes an upper end plate 1 and a lower end plate 12 that are parallel to each other. A support assembly is provided between the upper end plate 1 and the lower end plate 12. The support assembly includes a first support plate 2 and a second support plate 3 that are cross - perpendicularly arranged. The end faces at both ends of the first support plate 2 and the second support plate 3 are respectively perpendicular to the inner surfaces of the upper end plate 1 and the lower end plate 12. An installation bracket 7 is provided in the middle of the outer surfaces of the upper end plate 1 and the lower end plate 12. The surface of the installation bracket 7 is provided with fan - shaped grooves 8 arranged in a circular array. A circular groove 9 is provided in the middle of the fan - shaped grooves 8. Through - holes 10 are opened on the fan - shaped grooves 8; the first support plate 2 is rectangular, and the second support plate 3 includes a horizontal plate 16 with a rectangular middle part and connecting plates 17 that are arc - transitioned from the horizontal plate 16 to both end faces.

[0024] The upper end plate 1 and the lower end plate 12 are integrated by the support assembly. Welding end plates 11 are connected to the outer surfaces of both the upper end plate 1 and the lower end plate 12. A number of outward - protruding welding fulcrums 6 are provided on the outer surfaces of the welding end plates 11; the support column is attached to the inner wall of the fuel tank through the welding end plates 11 at both left and right ends to prevent the fuel tank from deforming under external forces, and the welding fulcrums 6 can prevent the welding end plates 11 from shifting.

[0025] The support assembly further includes a parallel plate 5 provided in the four column - shaped spaces formed by the intersection of the first support plate 2 and the second support plate 3. The parallel plate 5 is parallel to the second support plate 3. The parallel plate 5 increases the structural strength of the support assembly and improves the stability of the device.

[0026] On both sides of the plate surface of the first support plate 2, two reinforcing rib plates 4 are respectively provided. The reinforcing rib plates 4 are perpendicular to the parallel plate 5. The side edge of the first support plate 2 extends beyond the circumferential surface of the reinforcing rib plates 4, and the side edge of the second support plate 3 is within the circumferential surface of the reinforcing rib plates 4; the reinforcing rib plates 4 are semi-circular. The distances between the two outer side plates of the two reinforcing rib plates 4 away from each other are equal to the length between the upper end plate 1 and the lower end plate 12; the semi-circular reinforcing rib plates 4 help to disperse stress and improve the structural stability.

[0027] The mounting frame 7 is annular. A number of waist-shaped holes 13 are formed in the side surface of the mounting frame 7 along the circumferential direction. A clamping frame 14 adapted to the mounting frame 7 is provided on the inner side surface of the welded end plate 11. Waist-shaped columns 15 corresponding to the waist-shaped holes 13 are provided on the clamping frame 14; during installation, the clamping frame 14 is clamped under the mounting frame 7, and the waist-shaped columns 15 are correspondingly clamped into the waist-shaped holes 13.

[0028] When the support column of the present utility model is processed and manufactured, first, the welded end plates 11 at both ends are injection-molded. The welded end plates 11 are made of HDPE material, and the injection temperature of HDPE is generally 230 - 250 °C. Then, the middle support assembly is injection-molded. The support assembly is made of POM material, and the injection temperature of POM is generally 190 - 210 °C. During the overmolding process, the mounting frames 7 on the upper end plate 1 and the lower end plate 12 are firmly connected and fixed to the clamping frames 14 on the welded end plates 11. Since the injection temperature of POM is lower than that of HDPE and the melt index is higher than that of HDPE, when the support assembly is injection-molded, it will not cause the HDPE at the connection to melt and will not damage the structural strength at the connection between the two ends of the support column and the middle support column, improving the structural stability of the support column. When the support column is in use, the welded end plates 11 at the left and right ends are abutted against the inner wall of the fuel tank to prevent the fuel tank from deforming under external force. Welding fulcrums 6 protruding outward are provided on the welded end plates 11 to prevent the welded end plates 11 from shifting.

[0029] In this device, mounting brackets are provided on the outer surfaces of the upper end plate and the lower end plate of the support assembly. The mounting brackets are adapted to the clamping brackets inside the welded end plate. During installation, the clamping brackets are wrapped inside the mounting brackets, with a stable mounting structure, improving the structural strength at the joints between the two ends of the support column and the middle support column, enhancing the support effect of the support column, and preventing the fuel tank from deforming. The support assembly is made of POM material, with high mechanical strength, high fatigue resistance, and good resistance to organic solvents, being suitable for long-term support inside the fuel tank. The welded end plate is made of HDPE material, with high toughness and impact resistance. The wrapping with POM material can ensure the structural strength of the support column. This device has a simple structure, wide material sources, low manufacturing costs, is easy to produce and manufacture, is lightweight as a whole, does not have a great impact on the weight of the whole vehicle, is beneficial to reducing the driving power consumption of the vehicle, and is suitable for use in the fuel tank of a plug-in hybrid vehicle.
