[0027] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, not to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.

[0028] The vehicle tank and the automobile provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments and application scenarios.

[0029] The embodiments of the present application provide a vehicle tank, as shown in Figure 1 The vehicle tank comprises:

[0030] The upper tank shell 100, which reuses at least part of the structure of the vehicle body floor assembly;

[0031] The lower tank shell 200, which is connected with the upper tank shell 100;

[0032] The lower tank shell 200 forms an oil storage tank of the vehicle tank, and the upper tank shell 100 closes the oil storage tank through the connection with the lower tank shell 200.

[0033] The vehicle oil tank of the embodiment of the present application comprises an upper oil tank shell 100 and a lower oil tank shell 200 connected with the upper oil tank shell 100, wherein the upper oil tank shell 100 reuses at least part of the structure of a vehicle body floor assembly; the lower oil tank shell 200 forms an oil storage tank of the vehicle oil tank, and the upper oil tank shell 100 encloses the oil storage tank through the connection between the upper oil tank shell 100 and the lower oil tank shell 200. In this way, the upper oil tank shell does not need to be produced separately, the process step of manufacturing the upper oil tank shell in the production process of the oil tank is reduced, the production cost and difficulty are reduced, and the gap between the existing vehicle oil tank and the vehicle body floor is eliminated by reusing at least part of the structure of the vehicle body floor assembly as the upper oil tank shell 100, thereby increasing the volume of the vehicle oil tank.

[0034] As an optional implementation manner, as shown in Figure 1 and Figure 3 the lower oil tank shell 200 comprises a bottom plate 201 and a side plate 202 connected with the edge of the bottom plate 201; the bottom plate 201 and the side plate 202 form the oil storage tank, the top of the side plate 202 has a mounting plate 203 extending to the outside of the oil storage tank, and the lower oil tank shell 200 is connected with the upper oil tank shell 100 through the mounting plate 203.

[0035] Here, it should be noted that the shape of the bottom plate 201 of the lower oil tank shell 200 is matched with the shape of the upper oil tank shell 100, that is, the bottom plate 201 is designed in accordance with the structure of the vehicle body floor assembly reused by the upper oil tank shell 100, so that the volume of the vehicle oil tank can be further increased. Further, as shown in Figure 3 the number of side plates 202 included in the lower oil tank shell 200 is the same as the number of edges of the bottom plate 201, that is, one side plate 202 perpendicular to the bottom plate 201 is connected to each edge of the bottom plate 201, and each side plate 202 is located on the same side of the bottom plate 201, so that the bottom plate 201 and the plurality of side plates 202 can form the oil storage tank.

[0036] As a specific implementation manner, as shown in Figure 3 a plurality of first mounting holes 204 are formed in the mounting plate 203, and a second mounting hole corresponding to the first mounting hole 204 is formed in the upper oil tank shell 100, and a bolt connects the upper oil tank shell 100 and the lower oil tank shell 200 through the first mounting hole 204 and the second mounting hole.

[0037] In the specific implementation, the upper tank shell 100 and the lower tank shell 200 are connected by bolts, so that the upper tank shell 100 and the lower tank shell 200 can be quickly separated when the components in the vehicle tank are abnormal, and the maintenance efficiency of the components is improved.

[0038] Based on the specific implementation, as a more specific implementation, a sealing member or sealant is further arranged between the upper tank shell 100 and the mounting plate 203.

[0039] That is, a sealing member such as a sealing ring or a sealing gasket is placed between the assembly surface of the upper tank shell 100 and the assembly surface of the lower tank shell 200 (the surface of the mounting plate 203 facing the upper tank shell 100), or sealant is coated in the gap between the two assembly surfaces, so that the sealing treatment of the vehicle tank is achieved, and leakage of (liquid or gaseous) fuel is avoided.

[0040] As an optional implementation, as shown in Figure 1 and Figure 3 The bottom plate 201 of the lower tank shell 200 is provided with a fuel pump mounting seat 301, and a fuel pump 302 is mounted in the oil tank through the fuel pump mounting seat 301.

[0041] As an example, the fuel pump mounting seat 301 is arranged at the center of the bottom plate 201.

[0042] Here, it should be noted that in the vehicle tank of the embodiment of the present application, the upper tank shell 100 reuses at least part of the structure of the vehicle body floor assembly, so the fuel pump 302 cannot be embedded on the tank shell, but can only be installed inside the vehicle tank, so as shown in Figure 1 and Figure 3 The fuel pump mounting seat 301 is specifically mounted on the inner surface of the bottom plate 201, that is, the fuel pump mounting seat 301 is mounted in the oil tank, so that the fuel pump 302 is also located in the oil tank.

[0043] Based on the optional implementation, further, as an optional implementation, as shown in Figure 3As shown, the side plate of the oil tank lower shell 200 is further provided with an oil inlet 205, an oil outlet 206 and a third mounting hole 207; wherein the oil outlet 206 is connected with the fuel pump 302 through a pipeline, and the oil outlet 206 is connected with the engine through a pipeline, so that the fuel pumped out by the fuel pump 302 can be delivered to the engine to realize the normal driving of the vehicle; wherein the third mounting hole 207 is used for the power line harness of the fuel pump 302 to pass through, so as to realize the connection of the power line harness with the low-voltage storage battery in the vehicle, and the low-voltage storage battery provides working voltage for the fuel pump 302 to realize the normal operation of the fuel pump 302, wherein the vehicle oil tank further comprises an oil tank cover matched with the oil inlet 205.

[0044] As a specific example, again as Figure 3 As shown, the oil inlet 205 and the oil outlet 206 are arranged on the side plates on the opposite sides of the bottom plate 201, and the oil outlet 206 and the third mounting hole are arranged near the fuel pump 302, so that the length of the pipeline between the oil outlet 206 and the fuel pump 302, and the length of the power line harness of the fuel pump 302 can be shortened. Optionally, the oil inlet 205 is arranged on the side plate near the corner of the bottom plate 201, so as to facilitate the arrangement of the oil tank filler on the vehicle body in communication with the oil inlet 205.

[0045] As an optional implementation, the fourth mounting hole is arranged on the bottom plate 201, the fuel pump mounting seat 301 is mounted on the bottom plate 201 through the fourth mounting hole, and the fuel pump mounting seat 301 is clamped with the bottom plate 201.

[0046] On the basis of the above-mentioned optional implementation, the installation process of the fuel pump 302 is as follows: first, the fuel pump 302 is installed on the fuel pump mounting seat 301, then the fuel pump 302 is put into the oil storage groove through the fourth mounting hole, and at the same time, the fuel pump mounting seat 301 is clamped with the bottom plate 201. In this way, when the fuel pump 302 needs to be repaired, the oil tank upper shell 100 and the oil tank lower shell 200 do not need to be disassembled, and the fuel pump 302 can be directly disassembled through the fourth mounting hole, which improves the maintenance efficiency of the fuel pump 302.

[0047] On the basis of the above-mentioned optional implementation, the upper tank shell 100 and the lower tank shell 200 can be fixedly connected by welding, and sealing glue can be coated at the welding position. Of course, even if not on the basis of the above-mentioned optional implementation, that is, the fourth mounting hole is not formed on the bottom plate 201, and the fuel pump 302 and the fuel pump mounting seat 301 are located in the oil storage groove, the upper tank shell 100 and the lower tank shell 200 can also be fixedly connected by welding. In this case, when the fuel pump 302 is repaired, the upper tank shell 100 and the lower tank shell 200 need to be separated first.

[0048] As an optional implementation, as shown in Figure 1 and Figure 2 The upper tank shell 100 is composed of the left longitudinal beam 101, the right longitudinal beam 102, the front cross beam 103, the rear cross beam 104, and the floor panel 105 surrounded by the left longitudinal beam 101, the right longitudinal beam 102, the front cross beam 103, and the rear cross beam 104; wherein the lower tank shell 200 is connected with the left longitudinal beam 101, the right longitudinal beam 102, the front cross beam 103, and the rear cross beam 104.

[0049] That is, the lower surfaces (surfaces facing the lower tank shell 200) of the left longitudinal beam 101, the right longitudinal beam 102, the front cross beam 103, and the rear cross beam 104 are the assembly surfaces of the upper tank shell 100, so the second mounting holes are formed on the left longitudinal beam 101, the right longitudinal beam 102, the front cross beam 103, and the rear cross beam 104 at positions corresponding to the first mounting holes 204. The upper tank shell 100 and the lower tank shell 200 are threadedly connected by bolts of the first mounting holes 204 and the second mounting holes.

[0050] Compared with the existing tank, in order to avoid the left longitudinal beam 101, the right longitudinal beam 102, the front cross beam 103, and the rear cross beam 104, the upper tank shell is set as a special-shaped structure, in the above-mentioned optional implementation, the lower surfaces of the left longitudinal beam 101, the right longitudinal beam 102, the front cross beam 103, and the rear cross beam 104 are set as the assembly surfaces of the upper tank shell 100, which further enlarges the volume of the tank.

[0051] Here, it should be noted that the left longitudinal beam 101, the right longitudinal beam 102, the front cross beam 103, and the rear cross beam 104 can be multiple pieces of sheet metal spliced together, in which case the spliced parts of each piece of sheet metal need to be further sealed, for example, by coating sealing glue at the spliced parts to ensure the sealing of the tank.

[0052] As an optional implementation, the vehicle body floor assembly is integrally pressure-cast. In this way, the splicing process of different components can be reduced, the efficiency of assembly is improved, and the problem of poor sealing does not occur.

[0053] Embodiments of the present application also provide an automobile comprising the vehicle fuel tank as described above.

[0054] Finally, it should be noted that in this document, relational terms such as first and second and the like can only be used to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between or among the entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0055] The above is the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, can make several improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
