For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Unless otherwise specified, the front-to-back direction in the present application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0030] Reference below Figure 1-Figure 5 The vehicle body assembly 100 according to the embodiment of the present utility model is described. The vehicle body assembly 100 can meet the oil absorption demand of the vehicle under high-speed conditions, and can lower the installation center of gravity of the engine 5, thereby greatly improving the reliability of the vehicle.

[0031] like Figure 1-Figure 5 As shown, the vehicle body assembly 100 according to the embodiment of the utility model includes: two longitudinal beams 1 and an oil tank 3 .

[0032] The two longitudinal beams 1 are spaced apart in the transverse direction, and the oil tank 3 is located between the two longitudinal beams 1, that is, the two longitudinal beams 1 are spaced apart by a certain distance in the transverse direction of the vehicle, and the spacing distance is adapted to the installation size of the oil tank 3, so that the oil tank 3 can be installed between the two longitudinal beams 1 to avoid interference between the longitudinal beams 1 and the oil tank 3, which affects the installation of the oil tank 3, and a mounting beam 2 is connected between the two longitudinal beams 1, that is, one end of the mounting beam 2 is fixedly connected to one longitudinal beam 1, and the other end is fixedly connected to the other longitudinal beam 1, so that the mounting beam 2 is installed in the middle of the two longitudinal beams 1, and the two longitudinal beams 1 are connected, which can improve the stability, installation strength and rigidity of the two longitudinal beams 1.

[0033] The engine oil tank 3 is used to store engine oil, that is, there is engine oil inside, which can be delivered to other components for lubrication, etc. The engine oil tank 3 can be detachably mounted on the mounting beam 2. The engine oil tank 3 is connected to an oil inlet pipeline 31 and an oil return pipeline 32. The oil inlet pipeline 31 and the oil return pipeline 32 are used to be connected to the engine 5 respectively.

[0034] That is to say, the oil tank 3 can be installed on the mounting beam 2 by means of detachable connection methods such as bolts and screws, without the need for welding and fixing operations. Setting the oil tank 3 in a detachable connection method facilitates the easy installation of the oil tank 3 on the mounting beam 2 or removal from the mounting beam 2. This is flexible and convenient, and facilitates the disassembly and replacement of the oil tank 3 when it is damaged and needs to be replaced or repaired.

[0035] The oil tank 3 is provided with an oil inlet and an oil outlet, the oil inlet is connected to one end of the oil return pipeline 32, the oil outlet is connected to one end of the oil inlet pipeline 31, the other end of the oil return pipeline 32 is connected to the engine 5, and the other end of the oil inlet pipeline 31 is also connected to the engine 5. As a result, the engine oil in the oil tank 3 can flow out from the oil outlet into the oil inlet pipeline 31, and flow into the engine 5 through the oil inlet pipeline 31, so as to realize the transportation of the engine oil of the engine 5, so that the engine oil can lubricate the internal components of the engine 5, reduce friction and wear, and maintain the normal operation of the engine 5. The engine oil that has been cooled and lubricated in the engine 5 flows out from the engine 5 into the oil return pipeline 32, and flows into the oil tank 3 through the oil return pipeline 32 and the oil inlet, so as to realize the reflux of the engine oil into the oil tank 3, and complete the circulation of the engine oil between the engine 5 and the oil tank 3.

[0036] In actual design, the engine 5 can be provided with an oil pump to pump the oil into the oil return pipeline 32, and then pumped back into the oil tank 3. Therefore, by providing the oil tank 3 between the two longitudinal beams 1 to supply oil to the engine 5, it is not necessary to provide an oil pan to suck oil from the oil pan, which greatly reduces the difficulty of oil suction, thereby meeting the oil suction requirements of the vehicle when driving at high speeds, and canceling the provision of the oil pan, reducing the space occupied by the oil pan at the bottom of the engine 5, so that the overall height of the engine 5 can be effectively reduced, thereby reducing the installation center of gravity of the engine 5 on the whole vehicle, and improving the running performance of the whole vehicle.

[0037] In some embodiments, the vehicle body assembly 100 further includes a connecting bracket 4 , one end of which is connected to the oil tank 3 , and the other end is detachably connected to the mounting beam 2 , that is, the oil tank 3 can be connected to the mounting beam 2 via the connecting bracket 4 .

[0038] Specifically, Figure 2As shown, the connecting bracket 4 can be constructed as an L-shaped plate structure, that is, one end of the connecting bracket 4 is bent, and the two end faces form a certain angle, which can improve the strength of the connecting bracket 4, and one end thereof is connected to the outer peripheral surface of the engine oil tank 3. In practice, the engine oil tank 3 and the connecting bracket 4 can be fixedly connected to form an integral structure, thereby improving the connection reliability and stability of the connecting bracket 4 and the engine oil tank 3. The other end of the connecting bracket 4 is bent, and its bent surface is connected to the mounting beam 2 in a close fit, which can increase the contact area between the connecting bracket 4 and the mounting beam 2, improve the connection strength and rigidity between the two, and thus make the engine The oil tank 3 is stably and reliably mounted on the mounting beam 2, and the other bent end can be detachably connected to the mounting beam 2, that is, the other end can be connected to the mounting beam 2 by a detachable connection method such as bolts and screws. The connecting bracket 4 is set to be detachably connected to the mounting beam 2, which is convenient for easily installing the connecting bracket 4 on the mounting beam 2 or removing it from the mounting beam 2, which is flexible and convenient. When the oil tank 3 is damaged and needs to be replaced or repaired, it can be removed together with the connecting bracket 4 for replacement, which is flexible and convenient, and can be installed repeatedly, thereby increasing the service life of the oil tank 3.

[0039] In some embodiments, the connecting bracket 4 is located between the two longitudinal beams 1 and is distributed parallel to and spaced apart from the two longitudinal beams 1 .

[0040] like Figure 1 As shown, the two longitudinal beams 1 extend in different directions, and the connecting bracket 4 is installed between the two longitudinal beams 1 and is distributed parallel to and spaced apart from the two longitudinal beams 1 , which can ensure the uniformity of the force on the connecting bracket 4 and further ensure the stability of the oil tank 3 .

[0041] In some embodiments, there are multiple connecting brackets 4, that is, the number of connecting brackets 4 can be set to two, three, four or even more. Multiple connecting brackets 4 are set to connect the oil tank 3 with the mounting beam 2, which can provide multiple installation support points for the oil tank 3, so that the oil tank 3 is more stably and reliably connected to the mounting beam 2, reducing the risk of shaking and shifting of the oil tank 3, and thereby reducing the risk of oil supply to the engine 5.

[0042] And the plurality of connecting brackets 4 are distributed in parallel and spaced apart between the two longitudinal beams 1, that is, the plurality of connecting brackets 4 are parallel to each other, spaced apart from each other by a certain distance, and distributed in the space distance between the two longitudinal beams 1, such as Figure 2 As shown, two connecting brackets 4 are provided, and the two connecting brackets 4 are spaced apart, so that the connecting brackets 4 can be more evenly distributed between the longitudinal beams 1, providing uniform mounting support points on the outer peripheral surface of the oil tank 3, and connected to the mounting beam 2, so as to avoid uneven and unstable force on the outer peripheral surface of the oil tank 3, thereby improving the stability of the overall structure of the vehicle body assembly 100.

[0043] In some embodiments, the other end of the connecting bracket 4 is provided with a first connecting hole, the mounting beam 2 is provided with a second connecting hole, and the connecting bracket 4 is connected to the mounting beam 2 via a connecting member 41 which is sequentially passed through the first connecting hole and the second connecting hole.

[0044] Specifically, Figure 2 and Figure 5 As shown, a first connecting hole penetrating along the thickness direction is provided on the other bent end of the connecting bracket 4, and a second connecting hole is provided on the surface where the mounting beam 2 is connected to the connecting bracket 4. The size, shape and position of the first connecting hole and the second connecting hole are adapted to each other, so that the connecting member 41 can pass through the first connecting hole and the second connecting hole in sequence, and the connecting bracket 4 and the mounting beam 2 are reliably and accurately connected and fixed, thereby improving the connection stability between the two and facilitating installation and disassembly. When disassembling, the connecting member 41 only needs to be pulled out from the first connecting hole and the second connecting hole to realize the separation and disassembly of the connecting bracket 4 and the mounting beam 2.

[0045] In actual design, the connecting member 41 can be constructed as a connecting member 41 such as a bolt or a screw, that is, the first connecting hole and the second connecting hole can be constructed as threaded through holes, so that the bolts and screws can be inserted into the first connecting hole and the second connecting hole in sequence to connect and fix the connecting bracket 4 and the mounting beam 2.

[0046] It should be noted that the number of the connecting brackets 4 is not limited to that described in this embodiment, and can be flexibly adjusted according to actual needs and space size.

[0047] In some embodiments, the oil tank 3 is provided with an escape groove 33 , the inner wall surface of the escape groove 33 is the same as the contour of at least a portion of the outer side surface of the longitudinal beam 1 , and together define an escape gap 34 .

[0048] Specifically, Figure 2 and Figure 5As shown, the oil tank 3 is a cylindrical structure, and the whole is a sealed structure to prevent oil leakage. An avoidance groove 33 is arranged on the end surface of one end of the oil tank 3. Since the oil tank 3 is installed between the two longitudinal beams 1, and the projections of the oil tank 3 and the two longitudinal beams 1 in the lateral direction overlap, in order to prevent the oil tank 3 and the longitudinal beam 1 from interfering, the end surface of one end of the oil tank 3 overlaps with the projection of the longitudinal beam 1, and is recessed downward for a distance to form the avoidance groove 33, so that the inner wall surface of the avoidance groove 33 and the wheel of the outer side surface opposite to the longitudinal beam 1 The two longitudinal beams 1 have the same contour and jointly define an avoidance gap 34, that is, a certain gap is separated between the inner wall surface of the avoidance groove 33 and the outer side surface opposite to the longitudinal beam 1 to form an avoidance gap 34, which separates the oil tank 3 from the longitudinal beam 1. Such an arrangement can ensure that the oil tank 3 and the longitudinal beam 1 will not collide or interfere with each other during installation or use, thereby ensuring that the oil tank 3 is effectively and safely installed between the two longitudinal beams 1, and there is enough safe clearance between the longitudinal beam 1 during movement to prevent the oil tank 3 from being bumped or damaged due to shaking during vehicle operation.

[0049] In some embodiments, the center of gravity of the oil tank 3 is lower than the lower surface of the longitudinal beam 1 , that is, the center of the overall mass distribution of the oil tank 3 is located below the lower surface of the longitudinal beam 1 .

[0050] Specifically, Figure 3 As shown, the oil tank 3 is axially installed between the two longitudinal beams 1, and its axial center line is located below the lower surface of the longitudinal beam 1, that is, the center of gravity of the oil tank 3 is lower than the lower surface of the longitudinal beam 1, thereby enhancing the installation stability of the oil tank 3 and preventing the oil tank 3 from shaking or tilting during the operation of the vehicle. The burden of the oil tank 3 on the mounting beam 2 can be reduced, thereby improving the reliability of the mounting beam 2. Furthermore, since the lubrication system of the engine 5 is connected to the oil tank 3 for oil transportation, that is, the engine 5 does not need to be separately provided with an oil pan to absorb oil from the oil pan, the space occupied at the bottom of the engine 5 is reduced, the installation position of the engine 5 can be set lower, the installation center of gravity of the engine 5 is lowered, the stability of the engine 5 is further improved, and the normal operation of the engine 5 is ensured.

[0051] In some embodiments, at least a portion of the oil inlet line 31 is configured as a flexible section, which is suitable for bending and deformation, and / or at least a portion of the oil return line 32 is configured as a flexible section, which is suitable for bending and deformation.

[0052] Specifically, the parts where the oil inlet pipeline 31 and the oil return pipeline 32 are connected to the engine 5 can be set as flexible sections, and the flexible sections can bend and deform, so as to absorb and buffer the vibration and impact generated by the engine 5, reduce the damage to the oil inlet pipeline 31 and the oil return pipeline 32, and increase the service life of the oil inlet pipeline 31 and the oil return pipeline 32. At the same time, it is also conducive to the replacement and maintenance of the oil inlet pipeline 31 and the oil return pipeline 32, thereby improving convenience.

[0053] In actual design, at least a portion of the oil inlet pipeline 31 and the oil return pipeline 32 may be configured as a bellows.

[0054] The utility model also provides a vehicle.

[0055] The vehicle according to the embodiment of the utility model includes an engine 5 and a body assembly 100 of any one of the above-mentioned embodiments, wherein the engine 5 is located between the two longitudinal beams 1 and is distributed in sequence with the oil tank 3 along the longitudinal direction, that is, the engine 5 is installed between the two longitudinal beams 1 and is distributed in sequence with the oil tank 3 along the front and rear direction of the vehicle, so that the two longitudinal beams 1 can support and protect the sides of the oil tank 3 and the engine 5, thereby increasing the installation stability of the oil tank 3 and the engine 5.

[0056] Specifically, Figure 3 As shown, the oil tank 3 and the engine 5 are both installed between the two longitudinal beams 1 and are distributed in sequence along the front-rear direction of the vehicle, and the center of gravity of the oil tank 3 and the engine 5 are both located below the lower surface of the longitudinal beam 1. Therefore, by arranging the oil tank 3 between the two longitudinal beams 1 to supply oil to the engine 5, there is no need to arrange an oil pan to suck oil from the oil pan, which greatly reduces the difficulty of oil suction, thereby meeting the oil suction demand of the vehicle when driving at high speeds, and canceling the arrangement of the oil pan, reducing the space occupied by the oil pan at the bottom of the engine 5, so that the overall height of the engine 5 can be effectively reduced, thereby reducing the installation center of gravity of the engine 5 on the whole vehicle, improving the stability of the vehicle, ensuring the normal operation of the engine 5, and improving the running performance of the whole vehicle.

[0057] One end of the oil inlet pipeline 31 is sealed and connected to the engine 5 and the other end is sealed and connected to the oil tank 3 , and one end of the oil return pipeline 32 is sealed and connected to the engine 5 and the other end is sealed and connected to the oil tank 3 .

[0058] Specifically, Figure 3 As shown, one end of the oil inlet pipeline 31 is sealed and connected to the engine 5 to ensure that the engine oil can smoothly enter the engine 5 from this end to lubricate the internal components of the engine 5, and the other end of the oil inlet pipeline 31 is sealed and connected to the oil tank 3 to ensure that the engine oil can be smoothly transported from the oil tank 3 to the engine 5; similarly, one end of the oil return pipeline 32 is sealed and connected to the engine 5, and the other end is sealed and connected to the oil tank 3, so that the used oil in the engine 5 can smoothly flow back to the oil tank 3.

[0059] In actual design, in order to ensure the sealing of the connection, pipeline flanges can be set at both ends of the oil inlet pipeline 31 and the oil return pipeline 32, and sealing rings and corresponding mounting groove structures are designed on both sides of the pipeline flanges. The pipeline flanges are sealed and connected between the oil tank 3 and the engine 5 to prevent oil leakage.

[0060] Therefore, by reliably connecting the oil inlet line 31 and the oil return line 32 between the oil tank 3 and the engine 5, the oil can be smoothly transmitted and circulated between the two, thereby maintaining normal lubrication and heat dissipation of the engine 5, ensuring stable and reliable operation of the engine 5, and the sealed connection can prevent oil leakage, thereby ensuring the effectiveness and safety of the entire lubrication system.

[0061] In some embodiments, the engine 5 is provided with an oil inlet connected to the oil inlet line 31 and an oil return port connected to the oil return line 32, the oil inlet and the oil return port are provided on the same side of the engine 5, and the oil tank 3 is located on the side of the engine 5 where the oil inlet and the oil return port are provided.

[0062] Specifically, after the engine oil in the engine oil tank 3 flows into the oil inlet pipeline 31, it flows into the engine 5 through the oil inlet of the engine 5. The used engine oil in the engine 5 can flow out from the oil return port into the oil return pipeline 32, and then continue to flow back into the engine oil tank 3. The oil inlet and the oil return port are arranged on the same side of the engine 5. The oil inlet and the oil return port are arranged on the same side of the engine 5, which can facilitate the arrangement of the oil inlet pipeline 31 and the oil return pipeline 32 on the same side of the engine 5 for centralized arrangement and reduce the interlacing of the pipelines. At the same time, it is conducive to arranging the engine oil tank 3 on one side of the lubrication system of the engine 5, making the overall structure more compact, and reducing the length of the oil inlet pipeline 31 and the oil return pipeline 32 between the engine oil tank 3 and the engine 5, thereby reducing the amount of oil filling, improving the flow efficiency of the oil, and then improving the operating efficiency of the engine 5.
