Abstract
Description
Technical Field
[0001] Embodiments of the present disclosure relate to the field of plastic fuel tanks for vehicles, and in particular to an anti-deformation structure of a plastic fuel tank. Background Art
[0002] The anti-deformation structure placed in the fuel tank in the vehicle can support the fuel tank. Currently, the shape of the anti-deformation structure placed in the fuel tank in the vehicle is usually a columnar anti-deformation structure with the same cross-section and the same tensile resistance at each part.
[0003] However, in practice, when the fuel tank is supported by a columnar anti-deformation structure, the following technical problems often occur:
[0004] When the pressure inside the fuel tank is high, the fuel tank expands and deforms, and the anti-deformation structure inside the fuel tank is subjected to a large tensile force on the upper and lower sides of the fuel tank. Since the cross-section of the column is the same and relatively uniform, and each part of the column bears the same tensile force, it is not easy to break, causing damage to the side where the fuel tank is connected to the anti-deformation structure, resulting in damage to the fuel tank; the columnar anti-deformation structure is heavy, resulting in a heavy fuel tank and a large amount of material used to prepare the anti-deformation structure, resulting in increased fuel consumption of the vehicle and waste of anti-deformation structure materials; there are many types of fuel tanks, and the requirements for the bearing strength of the anti-deformation structure are different. Since the anti-deformation structure placed in the fuel tank is the same anti-deformation structure, the matching degree of the bearing strength of the anti-deformation structure and the fuel tank is poor, resulting in poor support effect on the fuel tank.

[0013] Optionally, the above-mentioned anti-deformation body is connected to at least one fuel tank noise reduction component, and the above-mentioned at least one fuel tank noise reduction component includes an assembled fuel tank noise reduction component and / or a secondary rubber-coated fuel tank noise reduction component.

[0016] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through a plastic fuel tank anti-deformation structure of some embodiments of the present disclosure, it is possible to reduce the damage to the side where the fuel tank is connected to the anti-deformation structure, reduce the damage to the fuel tank, reduce the weight of the fuel tank, reduce the material used to prepare the anti-deformation structure, reduce the increase in vehicle fuel consumption, and reduce the waste of anti-deformation structure materials. The anti-deformation structure's tensile tolerance is improved and matched with the fuel tank, and the support effect on the fuel tank is improved. The reasons for the frequent fuel tank damage, increased vehicle fuel consumption, more waste of anti-deformation structure materials and poor support effect on the fuel tank are as follows: when the pressure inside the fuel tank is high, the fuel tank expands and deforms, and the anti-deformation structure inside the fuel tank is subjected to a large tensile force on the upper and lower sides of the fuel tank. Since the cross-section of the column is the same and relatively uniform, and the tensile force borne by each part of the column is the same, it is not easy to break, causing damage to the side where the fuel tank and the anti-deformation structure are connected, resulting in damage to the fuel tank; the columnar anti-deformation structure is heavy, resulting in a heavy fuel tank and more materials used to prepare the anti-deformation structure, resulting in increased vehicle fuel consumption and waste of anti-deformation structure materials; there are many types of fuel tanks, and the requirements for the bearing strength of the anti-deformation structure are different. Since the anti-deformation structure placed in the fuel tank is the same anti-deformation structure, the matching degree of the bearing strength of the anti-deformation structure and the fuel tank is poor, resulting in poor support effect on the fuel tank. Based on this, the anti-deformation structure of the plastic fuel tank of some embodiments of the present disclosure is characterized in that the anti-deformation structure of the plastic fuel tank includes an anti-deformation body, an overflow cut-off valve and various fuel tank connection components, wherein the anti-deformation body includes a fracture pressure regulating structure, the tensile strength of the fracture pressure regulating structure is different from the tensile strength of other parts of the anti-deformation body, the tensile strength of the fracture pressure regulating structure is adjustable, and the tensile strength of the fracture pressure regulating structure is greater than 2000N; the anti-deformation structure of the plastic fuel tank is weight-reduced; the upper and lower ends of the anti-deformation body are connected to the fuel tank connection component; one end of each of the various fuel tank connection components is connected to the anti-deformation body, and the other end is connected to the side of the plastic fuel tank. Because the anti-deformation structure of the plastic fuel tank is weight-reduced, the weight of the anti-deformation structure of the plastic fuel tank can be reduced, thereby reducing the fuel consumption of the vehicle and the waste of anti-deformation structure materials. Also, because the above-mentioned plastic fuel tank anti-deformation structure includes a fracture pressure regulating structure, when the pressure inside the fuel tank is relatively high and the plastic fuel tank anti-deformation structure is subjected to a relatively high tensile force, the fracture pressure regulating structure of the above-mentioned plastic fuel tank anti-deformation structure has a different tensile tolerance from other parts, and thus the plastic fuel tank anti-deformation structure will fracture to protect the connection surface between the plastic fuel tank and the anti-deformation structure, thereby reducing damage to the side surface where the fuel tank and the anti-deformation structure are connected, and reducing damage to the fuel tank.Also, when preparing the anti-deformation structure of the plastic fuel tank, the tensile strength of the anti-deformation structure of the plastic fuel tank can be prepared according to the requirements of the fuel tank for the tensile strength, so the matching degree between the tensile strength of the anti-deformation structure of the plastic fuel tank and the fuel tank can be improved, and the supporting effect on the fuel tank can be improved. As a result, the damage to the side where the fuel tank and the anti-deformation structure of the plastic fuel tank are connected can be reduced, the fuel consumption of the vehicle can be reduced, and the waste of materials of the anti-deformation structure of the plastic fuel tank can be reduced, and the matching degree between the tensile strength of the anti-deformation structure of the plastic fuel tank and the fuel tank can be improved, and the supporting effect on the fuel tank can be improved.

[0027] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0028] Figure 1 A structural schematic diagram of the anti-deformation structure of a plastic fuel tank according to the present disclosure is shown.
[0029] like Figure 1 As shown, the anti-deformation structure of the plastic fuel tank may include an anti-deformation body 1, an overflow cut-off valve 15 and each tank connection component 2. The anti-deformation body 1 may include a fracture pressure regulating structure 3. The upper end and the lower end of the anti-deformation body 1 may be connected to the tank connection component 2. The anti-deformation body 1 may include at least one reinforcing rib 5. Each tank connection component 2 may be a hollow structure 7. Each tank connection component 2 may include a welding surface 6. The welding surface 6 may include at least one position detection component 13. The anti-deformation body 1 may be connected to at least one tank noise reduction component. The at least one tank noise reduction component may include an assembled tank noise reduction component 9 and / or a secondary rubber-coated tank noise reduction component 8. The assembled tank noise reduction component 9 and the secondary rubber-coated tank noise reduction component 8 may both be hollow structures 10. The overflow switching valve 15 may be connected to the tank noise reduction component. The overflow switching valve 15 may be connected to the tank noise reduction component in a snap-on connection. The overflow switching valve 15 can adjust the air pressure in the plastic fuel tank to make the air pressure in the plastic fuel tank more balanced, and can reduce the overflow in the plastic fuel tank when the plastic fuel tank is reversed or tilted. The anti-deformation structure of the plastic fuel tank can be weight-reduced. It should be noted that the weight-reduction treatment of the anti-deformation structure of the plastic fuel tank can be performed by setting a weight-reduction structure 4, such as Figure 1The weight reduction structure 4 shown. The method of weight reduction treatment of the above-mentioned plastic fuel tank anti-deformation structure is not specifically limited here. For example, the method of weight reduction treatment of the above-mentioned plastic fuel tank anti-deformation structure can also be to use lighter materials to prepare the plastic fuel tank anti-deformation structure.
[0030] In some embodiments, Figure 1As shown, the anti-deformation body 1 can be a solid waist-type pillar. It should be noted that the anti-deformation body 1 can be a solid structure or a hollow structure, which is not specifically limited here. The anti-deformation body 1 can include a fracture pressure regulating structure 3. The tensile force tolerance of the fracture pressure regulating structure 3 can be different from the tensile force tolerance of other parts of the anti-deformation body 1. The tensile force tolerance of the fracture pressure regulating structure 3 is adjustable. The tensile force tolerance of the fracture pressure regulating structure 3 can be greater than 2000N. Among them, the material of the anti-deformation body 1 can be POM or POK. Thereby, the weight of the plastic fuel tank can be reduced. It should be noted that the material of the anti-deformation body 1 can be various types of high-strength materials, and the specific type of the high-strength material of the anti-deformation body 1 is not limited here. The tensile force tolerance can characterize the tensile force of the plastic fuel tank that the anti-deformation body 1 can withstand. The fracture pressure regulating structure 3 can be used to adjust the tensile force tolerance of the anti-deformation body 1. The above-mentioned fracture pressure regulating structure 3 can be automatically disconnected when the pressure in the plastic fuel tank is too high and the anti-deformation structure of the plastic fuel tank is subjected to a large tensile force, so that the contact surface between the anti-deformation structure of the plastic fuel tank and the plastic fuel tank can be reduced when the pressure in the plastic fuel tank is too high, and the damage of the plastic fuel tank can be further reduced. It should be noted that due to the different types of plastic fuel tanks and the different tensile tolerances of the anti-deformation structures of the plastic fuel tanks matched with different types of plastic fuel tanks, the specific value of the pressure in the plastic fuel tank that causes the anti-deformation structure of the plastic fuel tank to fracture is not limited here. The reason why the tensile tolerance of the above-mentioned fracture pressure regulating structure 3 can be different from the tensile tolerance of other parts of the above-mentioned anti-deformation main body 1 is that the number of reinforcing ribs 5 included in the above-mentioned fracture pressure regulating structure 3 can be different from the number of reinforcing ribs 5 included in other parts of the above-mentioned anti-deformation main body 1. The above-mentioned fracture pressure regulating structure 3 can be located in the middle of the above-mentioned anti-deformation main body 1. The number of reinforcing ribs 5 included in the upper and lower parts of the above-mentioned anti-deformation main body 1 can be the same or different, and no specific limitation is made here. Because the number of reinforcing ribs 5 included in the upper and lower parts of the above-mentioned anti-deformation body 1 is different from the number of reinforcing ribs 5 included in the middle part of the above-mentioned anti-deformation body 1, the cross-sectional width of the middle part of the above-mentioned anti-deformation body 1 can be different from the cross-sectional width of the upper and lower parts of the above-mentioned anti-deformation body 1, and the tensile resistance of the middle part of the above-mentioned anti-deformation body 1 can be different from the tensile resistance of the upper and lower parts of the above-mentioned anti-deformation body 1. The above-mentioned fracture pressure regulating structure 3 can increase the number of reinforcing ribs 5 to expand the width of the cross section, thereby improving the tensile resistance of the anti-deformation structure of the plastic fuel tank. On the contrary, the above-mentioned fracture pressure regulating structure 3 can reduce the number of reinforcing ribs 5 to reduce the width of the cross section, thereby reducing the tensile resistance of the anti-deformation structure of the plastic fuel tank.Therefore, before preparing the anti-deformation structure of the plastic fuel tank, the number of reinforcing ribs 5 of the anti-deformation structure of the plastic fuel tank can be set according to the demand for the tensile force resistance of the anti-deformation structure of the plastic fuel tank to determine the tensile force resistance of the fracture pressure regulating structure 3. Therefore, the tensile force resistance of the prepared anti-deformation structure of the plastic fuel tank is not fixed, but can be set and adjusted according to the needs of the user before preparation, thereby improving the matching degree between the prepared anti-deformation structure of the plastic fuel tank and the plastic fuel tank.
[0031] In some embodiments, Figure 1 As shown, the above-mentioned anti-deformation structure of the plastic fuel tank may include a weight-reducing structure 4. The above-mentioned weight-reducing structure 4 may be a groove of the above-mentioned anti-deformation body 1. The above-mentioned weight-reducing structure 4 may be located between the various reinforcing ribs 5 included in the above-mentioned anti-deformation body 1. The above-mentioned weight-reducing structure 4 may reduce the weight of the prepared anti-deformation structure of the plastic fuel tank, thereby reducing the weight of the plastic fuel tank, so as to reduce the fuel consumption of the vehicle.

The material of the above-mentioned tank connection component 2 and the material of the plastic fuel tank can be the same. The way of connecting the above-mentioned tank connection component 2 and the side of the above-mentioned plastic fuel tank can be a melting connection. When the plastic fuel tank anti-deformation structure is placed on the side of the prepared plastic fuel tank blank, the residual temperature of the prepared plastic fuel tank blank can melt the above-mentioned tank connection component 2. The residual temperature of the above-mentioned plastic fuel tank blank is about 180°C.

The tensile strength of the fracture pressure regulating structure 3, the tensile strength of the upper part of the anti-deformation body 1 and the tensile strength of the lower part of the anti-deformation body 1 can be different. The tensile strength of the upper part of the anti-deformation body 1 and the tensile strength of the lower part of the anti-deformation body 1 can be the same or different, and no specific limitation is made here.

The above-mentioned fuel tank connection component 2 can be a flange after secondary injection molding, rubber coating and welding. It should be noted that the above-mentioned anti-deformation body and the above-mentioned each of the fuel tank connection components can be prepared by one-piece molding, can be an one-piece molding structure, and the material of the above-mentioned anti-deformation body and the above-mentioned each of the fuel tank connection components can be HDPE material.

[0037] Alternatively, if Figure 1 As shown, each of the above-mentioned fuel tank connection components 2 can be a hollow structure 7. Each of the above-mentioned fuel tank connection components 2 can communicate with the support component 11 embedded in the above-mentioned fuel tank connection component 2 including at least one exhaust hole 14. It should be noted that the fuel tank connection component 2 can communicate with the support component 11 embedded in the above-mentioned fuel tank connection component 2 including at least one exhaust hole 14, thereby, when the fuel tank connection component 2 and the plastic fuel tank are melted, the molten gas can be discharged. Here, each of the above-mentioned fuel tank connection components 2 can be a hollow structure 7 or a non-hollow structure, without specific limitation. It should be noted that when each of the above-mentioned fuel tank connection components is a non-hollow structure, the support component 11 in the above-mentioned fuel tank connection component 2 may not be provided with an exhaust hole.
[0038] Alternatively, if Figure 1 As shown, the upper part, the middle part and the lower part of the anti-deformation body 1 may each include at least one reinforcing rib 5. The upper part, the middle part and the lower part of the anti-deformation body 1 may each include at least one reinforcing rib 5.

The at least one reinforcing rib 5 may penetrate the anti-deformation body 1. The at least one reinforcing rib 5 may be located inside the anti-deformation body 1 in a transverse or longitudinal direction.
[0039] Alternatively, if Figure 1 As shown, the above-mentioned anti-deformation body 1 can be connected to at least one fuel tank noise reduction component. The above-mentioned anti-deformation body 1 is connected to at least one fuel tank noise reduction component.

The welding surface 6 includes at least one rectangular protrusion and at least one position detection component 13. The rectangular protrusion can increase the contact area between the welding surface 6 and the inner side of the plastic fuel tank, thereby reinforcing the connection strength between the anti-deformation structure of the plastic fuel tank and the inner side of the plastic fuel tank. The position detection component 13 can be a metal gasket. The position of the position detection component 13 inside the plastic fuel tank can be detected by a metal detection sensor to determine the position of the anti-deformation structure of the plastic fuel tank inside the plastic fuel tank. The protrusion of the welding surface 6 can be rectangular or cylindrical, which is not specifically limited here.
[0042] Optionally, the anti-deformation body may further include a sensor fixing assembly (not shown in the figure).

It should be noted that when a sensor needs to be installed in a plastic fuel tank, the sensor may be installed in the sensor fixing assembly.
[0043] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through a plastic fuel tank anti-deformation structure of some embodiments of the present disclosure, it is possible to reduce the damage to the side where the fuel tank is connected to the anti-deformation structure, reduce the damage to the fuel tank, reduce the weight of the fuel tank, reduce the material used to prepare the anti-deformation structure, reduce the increase in vehicle fuel consumption, and reduce the waste of anti-deformation structure materials. The anti-deformation structure's tensile tolerance is improved and matched with the fuel tank, and the support effect on the fuel tank is improved. The reasons for the frequent fuel tank damage, increased vehicle fuel consumption, more waste of anti-deformation structure materials and poor support effect on the fuel tank are as follows: when the pressure inside the fuel tank is high, the fuel tank expands and deforms, and the anti-deformation structure inside the fuel tank is subjected to a large tensile force on the upper and lower sides of the fuel tank. Since the cross-section of the column is the same and relatively uniform, and the tensile force borne by each part of the column is the same, it is not easy to break, causing damage to the side where the fuel tank and the anti-deformation structure are connected, resulting in damage to the fuel tank; the columnar anti-deformation structure is heavy, resulting in a heavy fuel tank and more materials used to prepare the anti-deformation structure, resulting in increased vehicle fuel consumption and waste of anti-deformation structure materials; there are many types of fuel tanks, and the requirements for the bearing strength of the anti-deformation structure are different. Since the anti-deformation structure placed in the fuel tank is the same anti-deformation structure, the matching degree of the bearing strength of the anti-deformation structure and the fuel tank is poor, resulting in poor support effect on the fuel tank. Based on this, the anti-deformation structure of the plastic fuel tank of some embodiments of the present disclosure is characterized in that the anti-deformation structure of the plastic fuel tank includes an anti-deformation body, an overflow cut-off valve and various fuel tank connection components, wherein the anti-deformation body includes a fracture pressure regulating structure, the tensile strength of the fracture pressure regulating structure is different from the tensile strength of other parts of the anti-deformation body, the tensile strength of the fracture pressure regulating structure is adjustable, and the tensile strength of the fracture pressure regulating structure is greater than 2000N; the anti-deformation structure of the plastic fuel tank is weight-reduced; the upper and lower ends of the anti-deformation body are connected to the fuel tank connection component; one end of each of the various fuel tank connection components is connected to the anti-deformation body, and the other end is connected to the side of the plastic fuel tank. Because the anti-deformation structure of the plastic fuel tank is weight-reduced, the weight of the anti-deformation structure of the plastic fuel tank can be reduced, thereby reducing the fuel consumption of the vehicle and the waste of anti-deformation structure materials. Also, because the above-mentioned plastic fuel tank anti-deformation structure includes a fracture pressure regulating structure, when the pressure inside the fuel tank is relatively high and the plastic fuel tank anti-deformation structure is subjected to a relatively high tensile force, the fracture pressure regulating structure of the above-mentioned plastic fuel tank anti-deformation structure has a different tensile tolerance from other parts, and thus the plastic fuel tank anti-deformation structure will fracture to protect the connection surface between the plastic fuel tank and the anti-deformation structure, thereby reducing damage to the side surface where the fuel tank and the anti-deformation structure are connected, and reducing damage to the fuel tank.Also, when preparing the anti-deformation structure of the plastic fuel tank, the tensile strength of the anti-deformation structure of the plastic fuel tank can be prepared according to the requirements of the fuel tank for the tensile strength, so the matching degree between the tensile strength of the anti-deformation structure of the plastic fuel tank and the fuel tank can be improved, and the supporting effect on the fuel tank can be improved. As a result, the damage to the side where the fuel tank and the anti-deformation structure of the plastic fuel tank are connected can be reduced, the fuel consumption of the vehicle can be reduced, and the waste of materials of the anti-deformation structure of the plastic fuel tank can be reduced, and the matching degree between the tensile strength of the anti-deformation structure of the plastic fuel tank and the fuel tank can be improved, and the supporting effect on the fuel tank can be improved.
