Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle body structure and a vehicle. Background Technology

[0002] Vehicle stability is a key factor in determining vehicle safety performance, especially when the vehicle is turning. If the vehicle's stability is poor, it is prone to problems such as skidding and rollover.

[0003] In the existing technology, hybrid vehicles suffer from poor vehicle stability due to unreasonable structural design of the vehicle body. Utility Model Content

[0042] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0043] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0044] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0045] In the embodiments of this application, "parallel," "perpendicular," and "equal" include the described situation and situations similar to the described situation, the range of which is within an acceptable deviation range, said acceptable deviation range being determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range for approximate parallelism may be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range for approximate perpendicularity may also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0046] This application provides a vehicle 100, which can be a hybrid electric vehicle 100, a plug-in hybrid electric vehicle 100, a range-extended electric vehicle 100, etc. The vehicle 100 can also be a sedan, truck, bus, lorry, trailer, etc.

[0047] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a vehicle 100 provided in an embodiment of this application. The vehicle 100 includes a body structure 10 and wheels 20. The body structure 10 is used for passengers to ride in and for carrying goods. The wheels 20 are installed under the body structure 10 to support the body structure 10 and are able to roll on the road surface so that the vehicle 100 can move.

[0048] For ease of understanding, this application uses a plug-in hybrid electric vehicle 100 as an example for illustration.

[0049] The vehicle body structure 10 includes a floor 2 and seats. The floor 2 supports the seats for passenger seating. The seats may include front seats 61 and rear seats 62. The floor 2 may also include a front floor 21 and a rear floor 22. The front floor 21 supports the front seats 61, and the rear floor 22 supports the rear seats 62. The front seats 61 refer to the driver's seat and the front passenger seat, and the rear seats 62 may be a single row, two rows, or multiple rows.

[0050] The vehicle body structure 10 also includes a front frame 1. The front frame 1 is located below the front of the vehicle 100 and supports the front engine compartment, where components such as the engine and air conditioning system can be installed. The engine provides driving force to the vehicle 100 to propel it. The air conditioning system regulates the interior temperature to improve the comfort of the passengers.

[0051] The vehicle body structure 10 may also include a fuel tank 4 located below the floor 2. The fuel tank 4 can provide fuel to the engine, and the engine burns fuel to provide power to the vehicle 100 to drive the vehicle 100.

[0052] Corresponding to the plug-in hybrid vehicle 100, the body structure 10 may also include a battery pack 3, which is located below the floor 2. The battery pack 3 can supply power to the vehicle 100, for example, it can supply power to the air conditioner to enable the air conditioner to work and regulate the temperature. The battery pack 3 can also supply power to the motor, which drives the wheels 20 to rotate, thereby driving the vehicle 100.

[0053] In some implementations, see Figure 2 , Figure 3 , Figure 4 and Figure 5 The vehicle body structure 10 includes a front frame 1, a floor 2, a fuel tank 4, and a battery pack 3. Along the length of the vehicle body structure 10, the front frame 1 is connected to the front side of the floor 2, and the fuel tank 4 and the battery pack 3 are both located below the floor 2. The fuel tank 4 is located between the battery pack 3 and the front frame 1.

[0054] In the above design, the front frame 1 is located below the front of the vehicle. The upper part of the front frame 1 is the front engine compartment, which typically houses components such as the engine and air conditioning system, resulting in a significant weight in the front engine compartment. If the battery pack 3 is close to the front frame 1, the vehicle's center of gravity will be too close to the front of the vehicle, affecting the grip of the wheels 20 during cornering and causing the vehicle to slip. Placing the fuel tank 4 between the battery pack 3 and the front frame 1, since the battery pack 3 is typically heavier than the fuel tank 4, prevents the vehicle's center of gravity from being too close to the front of the vehicle, thus improving the vehicle's stability.

[0055] In some examples, the vehicle body structure 10 may include a main frame 5 located below the floor 2. The main frame 5 is connected to the front frame 1 near the front of the vehicle and to the rear frame 9 near the rear. The front frame 1 is located below the front engine compartment and supports the engine compartment, while the rear frame 9 is located below the trunk and supports the trunk. The front frame 1 and the rear frame 9 can be connected to the main frame 5 by welding or bolting.

[0056] In some examples, both the battery pack 3 and the fuel tank 4 can be connected to the main frame 5 of the vehicle body structure 10.

[0057] In some implementations, see Figure 4The main frame 5 of the vehicle body structure 10 includes a crossbeam 51, a first longitudinal beam 52, and a second longitudinal beam 53. The first longitudinal beam 52 and the second longitudinal beam 53 are spaced apart along the width direction of the vehicle body structure 10. The crossbeam 51 is located at the end of the first longitudinal beam 52 and the second longitudinal beam 53 facing the front frame 1. The battery pack 3 is connected between the first longitudinal beam 52 and the second longitudinal beam 53, and the fuel tank 4 is located within the space enclosed by the first longitudinal beam 52, the second longitudinal beam 53, and the crossbeam 51.

[0058] In the above scheme, due to the relatively high strength of the first longitudinal beam 52 and the second longitudinal beam 53, the battery pack 3 is connected between the first longitudinal beam 52 and the second longitudinal beam 53, which improves the stability of the connection between the battery pack 3 and the main frame 5. The fuel tank 4 is located in the space enclosed by the first longitudinal beam 52, the second longitudinal beam 53 and the crossbeam 51. The first longitudinal beam 52, the second longitudinal beam 53 and the crossbeam 51 protect the fuel tank 4 from collisions during vehicle 100 operation, thereby improving the safety of the fuel tank 4.

[0059] In some examples, the first longitudinal beam 52 and the second longitudinal beam 53 are welded to the crossbeam 51.

[0060] In some examples, the fuel tank 4 includes an upper surface 41 and a lower surface 42, which are arranged along the height direction of the vehicle body structure 10. The lower surface 42 is higher than the lower surface of the crossbeam 51.

[0061] In other examples, the height of the lower surface 42 of the tank is lower than the height of the lower surface of the crossbeam 51.

[0062] In some embodiments, a protective structure is also included, which is located on the side of the fuel tank 4 facing the crossbeam 51. Since the fuel tank 4 and the battery pack 3 are arranged sequentially from the front to the rear of the vehicle, the side of the fuel tank 4 facing the crossbeam 51 is closer to the front of the vehicle. When the vehicle 100 is in motion, the protective structure can protect the fuel tank 4 and the battery pack 3 from collisions with foreign objects on the road, thereby improving the safety of the vehicle 100.

[0063] In some examples, the protective structure can be a protective beam.

[0064] In other examples, the protective structure can be a protective plate.

[0065] In some examples, the protective structure can be connected to the crossbeam 51 by bolts or welding.

[0066] In other examples, the protective structure can be connected to the first longitudinal beam 52 and the second longitudinal beam 53 at both ends by bolts or welding.

[0067] In some embodiments, the projections of the fuel tank 4 and the front frame 1 at least partially overlap along the length of the vehicle body structure 10. This causes at least a portion of the front frame 1 to be lower than the upper surface 41 of the fuel tank, thereby protecting the fuel tank 4 and improving its safety.

[0068] In some examples, along the height direction of the vehicle body structure 10, the lower surface 42 of the fuel tank is higher than the lower surface of the front frame 1, but lower than the upper surface of the front frame 1.

[0069] In other examples, along the height direction of the vehicle body structure 10, the lower surface 42 of the fuel tank is flush with the lower surface of the front frame 1.

[0070] In some other examples, along the height direction of the vehicle body structure 10, the lower surface 42 of the fuel tank is lower than the lower surface of the front frame 1, but the upper surface 41 of the fuel tank is higher than the lower surface of the front frame 1.

[0071] In some implementations, see Figure 5 Floor 2 includes a front floor 21 and a rear floor 22. The front floor 21 is used to support the front seat 61, and the rear floor 22 is used to support the rear seat 62. A part of the battery pack 3 is connected to the rear floor 22, and another part of the battery pack 3 is connected to the front floor 21. The fuel tank 4 is connected to the front floor 21.

[0072] The battery pack 3 is connected in part to the rear floor 22 and in part to the front floor 21. The fuel tank 4 is connected to the front floor 21, so that the position of the battery pack 3 is relatively far away from the front frame 1, thereby shifting the center of gravity of the vehicle body structure 10 to the rear and improving the stability of the vehicle 100.

[0073] In some other embodiments, the battery pack 3 is connected to the rear floor 22, and the fuel tank 4 is connected to the front floor 21.

[0074] In some implementations, see Figure 2 and Figure 3 The vehicle body structure 10 includes a front side panel 71 and an oil inlet pipe 44. The front side panel 71 is provided with a filler neck 43, and the oil inlet pipe 44 connects the filler neck 43 and the fuel tank 4. Since the fuel tank 4 is located between the battery pack 3 and the front frame 1, placing the filler neck 43 in the front side panel 71 of the vehicle 100 reduces the distance between the filler neck 43 and the fuel tank 4 compared to placing the filler neck 43 in the rear side panel of the vehicle 100, thereby reducing the length of the oil inlet pipe 44 and lowering the production cost of the vehicle 100.

[0075] In some examples, a left front side panel 71 and a right front side panel 71 are provided on both sides of the vehicle body structure 10 in the width direction, and the fuel filler 43 can be provided on either the left front side panel 71 or the right front side panel 71.

[0076] In some other embodiments, the fuel filler 43 is located on the rear side panel 72.

[0077] In some implementations, see Figure 2 and Figure 3 The vehicle body structure 10 includes a front wheel cover 8 and a mudguard. Along the height direction of the vehicle body structure 10, the front wheel cover 8 and the mudguard are located above the front frame 1. The mudguard is connected to the front wheel cover 8 and is adapted to be located between the wheel 20 and the front wheel cover 8. The oil inlet pipe 44 is provided in the gap between the front wheel cover 8 and the mudguard.

[0078] In the above scheme, the oil inlet pipe 44 is placed in the gap between the front wheel cover 8 and the mudguard, which improves the space utilization rate between the front wheel cover 8 and the mudguard of the vehicle 100.

[0079] In some examples, the oil inlet line 44 can be connected to the front wheel arch 8 via cable ties.

[0080] In other examples, pipe clamps can be connected to the front wheel arch 8 by bolts, and the oil inlet pipe 44 can be fixed to the front wheel arch 8 by the pipe clamps.

[0081] In some examples, the mudguards can be secured to the front wheel arch 8 using rivet clips.

[0082] In other examples, the mudguards can be bolted to the front wheel arch 8.

[0083] In some implementations, see Figure 2 and Figure 3 The vehicle body structure 10 includes an oil outlet pipe structure adapted to connect the fuel tank 4 and the engine. The vehicle body structure 10 also includes a front wheel arch 8 and a mudguard. Along the height direction of the vehicle body structure 10, the front wheel arch 8 and the mudguard are located above the front frame 1. The mudguard is connected to the front wheel arch 8 and is adapted to be positioned between the wheel 20 and the front wheel arch 8. A portion of the oil outlet pipe structure is located in the gap between the front wheel arch 8 and the mudguard. Placing a portion of the oil outlet pipe structure in the gap between the front wheel arch 8 and the mudguard improves the space utilization between them.

[0084] It should be understood that the connection method between the oil outlet pipe structure and the front wheel cover 8 can be set with reference to the connection method between the oil inlet pipe and the front wheel cover 8, and will not be elaborated here.

[0085] In some examples, portions of the oil inlet and outlet pipeline structures are simultaneously located in the gap between the front wheel arch 8 and the mudguard.

[0086] In some specific implementation methods, see [reference] Figure 2The oil outlet pipeline structure includes a carbon canister 45, which is located in the gap between the front wheel arch 8 and the mudguard. Placing the carbon canister 45 in the gap between the front wheel arch 8 and the mudguard improves the space utilization rate between the front wheel arch 8 and the mudguard.

[0087] In some embodiments, the fuel line structure includes a first line and a second line. The first line connects the fuel tank 4 and the carbon canister 45, and the second line connects the carbon canister 45 and the engine. At least a portion of the first line and / or at least a portion of the second line is located in the gap between the front wheel arch 8 and the mudguard. By also placing at least a portion of the first line and / or the second line connected to the carbon canister 45 in the gap between the front wheel arch 8 and the mudguard, the space utilization between the front wheel arch 8 and the mudguard is further improved.

[0088] In some examples, the carbon canister 45 collects the oil vapor that evaporates in the fuel tank 4 through a first pipe, and guides the oil vapor to the engine for combustion through a second pipe, which reduces environmental pollution caused by fuel evaporation and improves fuel efficiency.

[0089] In some examples, at least a portion of the first pipe is located in the gap between the front wheel arch 8 and the fender.

[0090] In other examples, at least a portion of the second pipe is located in the gap between the front wheel arch 8 and the fender.

[0091] In some other examples, at least a portion of the first pipe and at least a portion of the second pipe are simultaneously located in the gap between the front wheel arch 8 and the fender.

[0092] In some implementations, see Figure 2 , Figure 4 and Figure 5 The fuel tank 4 has a flat structure, and its thickness direction is consistent with the height direction of the vehicle body structure 10. By making the fuel tank 4 flat, the space occupied by the fuel tank 4 in the height direction of the vehicle body structure 10 is reduced. This eliminates the need for a protruding structure on the front floor 21 above the fuel tank 4, thereby increasing the space between the front floor 21 and the roof of the vehicle 100 and improving passenger comfort.

[0093] It should be noted that the flat structure of fuel tank 4 means that the thickness dimension of fuel tank 4 is relatively small, making fuel tank 4 flat.

[0094] In some examples, tank 4 can be an approximate cuboid structure.

[0095] In other examples, the fuel tank 4 is a cylindrical structure along the height of the vehicle body structure.

[0096] In some examples, see Figure 6The fuel tank 4 may be provided with a connection hole 46, wherein the connection hole 46 extends through the thickness direction of the fuel tank 4. The fuel tank 4 can be connected to the main frame 5 of the vehicle 100 by bolts passing through the connection hole 46.

[0097] In some examples, the fuel tank 4 may also be equipped with support members 47, such as support columns or support plates. One end of the support member 47 is welded to the lower surface 42 of the fuel tank, and the other end of the support member 47 is welded to the upper surface 41 of the fuel tank. By providing the support member 47, the strength of the fuel tank 4 is improved, and deformation of the fuel tank 4 is prevented. For example, a through hole can be drilled along the thickness direction of the fuel tank 4, the support member 47 can be inserted through the through hole, and then the upper surface 41 and the lower surface 42 of the fuel tank can be welded and sealed to the support member 47 respectively.

[0098] In some examples, the oil tank 4 also includes an oil pump system 48 for pumping oil. The upper surface 41 of the oil tank may be provided with a recessed area, within which the oil pump system 48 is disposed, to reduce the thickness dimension of the oil tank 4.

[0099] In some implementations, see Figure 5 Floor 2 includes a front floor 21 and a rear floor 22. The front floor 21 supports the front seats 61, and the rear floor 22 supports the rear seats 62. The front floor 21 and the rear floor 22 are flush. Compared with the existing vehicle 100 where the rear floor 22 has a raised structure, the flush arrangement of the front floor 21 and the rear floor 22 increases the legroom of the rear seats 62 and improves the comfort of the vehicle 100.

[0100] In some embodiments, the vehicle body structure 10 further includes a charging port structure 31, which is electrically connected to the battery pack 3. By charging the battery pack 3 through the charging port structure 31, the battery pack 3 can be quickly replenished with power, thereby improving the charging speed of the battery pack 3.

[0101] Since the fuel filler 43 is located on the front panel 71, the position of the rear panel 72 of the vehicle 100 is left empty. The charging port structure 31 of the vehicle 100 can be located on the rear panel 72 of either side of the vehicle 100, which improves the flexibility of the charging port structure 31.

[0102] In some other embodiments, the battery pack 3 can be charged by running an engine. For example, the engine can drive a generator to charge the battery pack 3.

[0103] In some implementations, see Figure 3The charging port structure 31 includes a first charging port structure and a second charging port structure, which are respectively located on both sides of the vehicle body structure 10 along the width direction of the vehicle body structure 10. The presence of the first and second charging port structures on both sides of the vehicle body structure 10 allows for convenient charging of the battery pack 3 through either charging port structure 31 on one side; it also allows for simultaneous charging of the battery pack 3 through both the first and second charging port structures, improving charging efficiency.

[0104] In some examples, the first charging port structure and the second charging port structure are connected in parallel.

[0105] In some other embodiments, the first charging port structure and the second charging port structure are located on the same side in the width direction of the vehicle body structure 10.

[0106] In some embodiments, the vehicle body structure 10 includes a first rear side panel and a second rear side panel, with a first charging port structure disposed on the first rear side panel and a second charging port structure disposed on the second rear side panel. This makes the first and second charging port structures symmetrically arranged on both sides of the vehicle body structure 10 in the width direction, improving the aesthetic appearance of the vehicle 100.

[0107] Meanwhile, since the technical solution in this embodiment places the fuel tank 4 between the battery pack 3 and the front frame 1, compared with the existing technical solution, it is equivalent to moving the battery pack 3 backward, reducing the distance between the battery pack 3 and the charging port structure 31, shortening the length of the charging line between the battery pack 3 and the charging port structure 31, and saving materials.

[0108] In other embodiments, the first charging port structure can be located at the front of the vehicle, such as at the front side panel 71. The second charging port structure can be located at the rear of the vehicle, such as at the trunk door panel.

[0109] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0110] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
