Description

TECHNICAL FIELD

[0001] The present application relates to a hybrid vehicle having an improved arrangement, and more particularly, to a hybrid vehicle having an improved arrangement which mounts a fuel tank on a lower surface of an exterior of a vehicle body, mounts a battery between a floor of an interior of the vehicle body and a rear seat, and positions the fuel tank more forward than the battery. BACKGROUND

[0002] Generally, a hybrid vehicle such as a plug-in hybrid electric vehicle (PHEV) and a hybrid electric vehicle (HEV) refers to a vehicle driven by a gasoline engine and an electric motor separately installed therein, and when the vehicle travels in a low-efficiency travel environment by using the gasoline engine, the efficiency of the entire system can be improved by charging the electric motor.

[0003] Because the hybrid vehicle travels using only the electric motor after stopping the engine without the need for engine power, harmful emissions can be reduced, and noise and fuel efficiency of the vehicle can be improved. In recent years, according to demands such as emission regulations and improvement of fuel efficiency, the demand for a hybrid vehicle capable of reducing harmful emissions is increasing.

[0004] The hybrid vehicle includes an engine installed together with an electric motor as a driving source of the vehicle, and a fuel tank to store liquid fuel for driving the engine and a high-voltage battery to provide electric power to drive the electric motor together are provided. Since the high-voltage battery is a high-voltage electrical component in which explosion and malfunction can occur due to water or impact, the high-voltage battery must be installed in an interior of the vehicle.

[0005] Conventionally, the high-voltage battery is installed in a separate interior space of the rear of the vehicle, that is, the lower side of the trunk, which makes it difficult to secure sufficient trunk space. In other words, when the high-voltage battery is installed to the lower side of the trunk of the rear of the vehicle, the capacity of the trunk area is inevitably reduced, thus reducing the marketability of the trunk space in the vehicle, deteriorating the weight distribution of the vehicle, etc.

[0006] As described above, by installing the high-voltage battery at the bottom of the trunk, the trunk space for various purposes is reduced, making it more difficult to store a spare tire or the like therein. In addition, when the high-voltage battery having a considerable weight is intended to be installed in another interior space other than the trunk to secure the capacity of the trunk area in a narrow vehicle space, there is no structural countermeasure for the vehicle body structure and the battery mounting structure for securing the space, securing the rigidity of the battery mounting portion, reinforcing the crash performance, etc., the arrangement structure of the battery and the fuel tank, etc.

[0007] Figure 1is a perspective view of a vehicle including a fuel tank and a battery as related art. As shown, a T-shaped battery 20 is included in the center of the vehicle, and a fuel tank 10 is disposed behind the battery 20. In particular, the center floor of the vehicle is raised, and the space occupied by the battery 20 is large, thereby narrowing the interior space.

[0008] The above information disclosed in this section is only for the purpose of enhancing the understanding of the background of the application, and therefore it can contain information that is not known to those of ordinary skill in the art in the prior art. SUMMARY

[0009] The present application provides a hybrid vehicle having an improved arrangement that changes the mounting position of a high-voltage battery in the hybrid vehicle from the existing position of the trunk to the lower portion of the rear seat.

[0010] Further, the present application provides a hybrid vehicle having an improved arrangement that disposes a fuel tank and a battery together in the space below the rear seat, and disposes the fuel tank outside the vehicle body more forward than the battery inside the vehicle body. Still further, the present application provides a hybrid vehicle having an improved arrangement that applies a rear suspension to the battery.

[0028] In the following, exemplary embodiments of the present application will be described in more detail with reference to the accompanying drawings. The exemplary embodiments of the present application can be modified in various forms, and the scope of the present application should not be construed as being limited to the following exemplary embodiments. The exemplary embodiments are provided to more completely explain the present application to those skilled in the art

[0029] Also, the terms such as "…unit" described in the specification mean a unit for processing at least one function or operation, which can be implemented as a combination of hardware. In the present specification, the names of components are divided into first, second, and the like in order to distinguish them because the names of components are the same and are not necessarily limited to the order in the following description. Also, in the present specification, when the longitudinal direction is the front-rear direction of the vehicle body longitudinal direction, the lateral direction refers to the left-right direction of the vehicle body width direction.

[0030] The present application relates to a hybrid vehicle having an improved arrangement structure, Figure 2 is a side sectional view of a main part of a hybrid vehicle having an improved arrangement structure as an exemplary embodiment of the present application. Referring to Figure 2 A hybrid vehicle having an improved arrangement structure according to an exemplary embodiment of the present application can include a fuel tank 110 that supplies fuel to an engine, and a battery 210 that supplies electric driving power to a vehicle, the fuel tank 110 can be disposed in a first area 100 that is recessed upward from a lower surface of the vehicle body exterior, the battery 210 can be disposed in a second area 200 that is recessed downward from a bottom of the vehicle body interior and is located below a rear seat, and the first area 100 can be more forward than the second area 200 in a longitudinal direction of the vehicle body.

[0031] Also, a height of a lower surface of the second area 200 can be lower than a height of an upper surface of the first area 100. In general, a hybrid vehicle refers to a vehicle that is driven by effectively combining two or more different types of power sources, but mainly refers to a vehicle that obtains driving power by using an engine that uses fuel and an electric motor that is driven by power of a battery, which is called a hybrid electric vehicle (HEV). An electric vehicle refers to all vehicles that use electric power as a power source, and can include a plug-in hybrid electric vehicle (PHEV) that uses electric power as a part of a power source. Hereinafter, the hybrid electric vehicle is referred to as a hybrid vehicle.

[0032] The first area 100 can be an area that is recessed upward from a lower surface of the vehicle exterior. The upwardly recessed shape of the first area 100 can be formed to correspond to the shape of the fuel tank 110, and thus, when the fuel tank 110 is inserted from the bottom to the top, a separation space between the vehicle body bottom portion 500 and the fuel tank 110 can be minimized. The second area 200 can be an area that is recessed downward between the bottom of the vehicle body interior and the rear seat 300. The downwardly recessed shape of the second area 200 can be formed to correspond to the shape of the battery 210, and thus, when the battery 210 is inserted from the top to the bottom, a separation space between the vehicle body bottom portion 500 and the battery 210 can be minimized.

[0033] Further, the first region 100 can be disposed more forward than the second region 200 in the longitudinal direction of the vehicle body. When the fuel tank 110 and the battery 210 are both disposed under the rear seat 300, the fuel tank 110 and the battery 210 need to be located inside the vehicle body, and the relatively heavy battery 210 can be disposed more rearward than the fuel tank 110 in the longitudinal direction of the vehicle, and thus the first region 100 and the second region 200 can be a structural countermeasure for the arrangement of the battery 210 and the fuel tank 110 to secure space when the high-voltage battery 210 is intended to be installed in another internal space other than the trunk.

[0034] The fuel tank 110 can store liquid fuel for driving the engine, and can supply fuel to the engine, and can be disposed in the first region 100 that is recessed upward from the lower surface of the vehicle body exterior. The hybrid vehicle equipped with the engine can be installed with a fuel pump configured to pump liquid fuel in the fuel tank 110 in which fuel is stored, and configured to inject the fuel pumped by the fuel pump into the combustion chamber of the engine through an injector.

[0035] The battery 210 can be installed to the vehicle body to store electric energy, and can supply electric driving power to the vehicle, and can be disposed in the second region 200 that is recessed downward between the bottom of the vehicle body interior and the rear seat 300. The battery 210 can be disposed more rearward than the fuel tank 110 with respect to the longitudinal direction of the vehicle.

[0036] The battery 210 can be directly charged by an external power source, or can be charged by a power conversion system such as a drive motor inverter, a low-voltage step-down DC-DC converter, a step-up DC-DC converter, or a built-in charger. Specifically, the battery 210 can be divided into one or more to be connected to one or more alternators, respectively. For example, if a battery 210 of 48 V is required, it can be used by connecting four 12 V batteries 210 in parallel, connecting four 12 V alternators respectively, or connecting two 24 V alternators respectively to the four batteries 210.

[0037] The battery 210 type can be a lead-acid battery, a nickel-hydrogen (Ni-MH) battery, a lithium-ion battery, a nickel-cadmium battery, a lithium polymer battery, an air zinc battery, a sodium sulfur battery, and a sodium nickel chloride battery, and the present application is not particularly limited thereto. In addition, the height of the lower surface of the second region 200 can be lower than the height of the upper surface of the first region 100.

[0038] The underbody portion 500 can have a curved cross-sectional shape that is concave downward, and thus, a portion of the underbody portion 500 of the second region 200 in which the battery 210 is installed can have a lower height than a portion of the underbody portion 500 of the first region 100 in which the fuel tank 110 is installed. Accordingly, an installation space of the fuel tank 110 can be formed in front of the battery 210. Also, the third cross member 230 installed in the vehicle transverse direction can be installed on the upper surface of the lower side of the curved portion of the underbody portion 500, and the second cross member 220 installed in the vehicle transverse direction can be installed on the lower surface of the upper side of the curved portion of the underbody portion 500. The underbody portion 500 of the first region 100 in which the fuel tank 110 is installed can form an inclined surface that gradually rises upward from front to rear, and the first cross member 120 installed in the vehicle transverse direction can be installed on the lower surface of the rear portion of the inclined surface.

[0039] An exemplary embodiment of the present application can be a hybrid vehicle having two rows, three rows, or more rows of seats. The hybrid vehicle having an improved arrangement according to the exemplary embodiment of the present application can further include a first cross member 120 fastened to one end of the front portion of the rear seat 300 in the vehicle longitudinal direction and one end of the fuel tank 110 and disposed in the first region 100, and a second cross member 220 fastened to one end of the rear portion of the rear seat 300 in the vehicle longitudinal direction and one end of the rear portion of the battery 210 in the vehicle longitudinal direction and located in the second region 200.

[0040] Also, the hybrid vehicle can further include a third cross member 230 fastened to one end of the rear portion of the fuel tank 110 and one end of the front portion of the battery 210 and disposed in the second region 200 adjacent to the first region 100. The first cross member 120 can be installed to be longitudinally disposed toward the left and right in the transverse direction of the vehicle body, as Figure 3 shown, in the first region 100 disposed on the lower side of the underbody portion 500, i.e., outside the vehicle. Referring to Figure 3 , the fuel tank 110 can be disposed rearward of the first cross member 120. One end of the fuel tank 110 can be fastened to the first cross member 120. In other words, the fuel tank 110 can have one end secured using a mounting bracket formed on the first cross member 120 and located in the first region 100.

[0041] The rear seat 300 may also have a lower end fastened to the front of the first transverse member 120 in the longitudinal direction of the vehicle body. Because the rear seat 300 can be located inside the vehicle, the first transverse member 120, located outside the vehicle, can be installed through the bottom portion 500 of the vehicle body and fastened to the seat frame by a mounting bracket to secure the rear seat 300. The second transverse member 220 can be installed longitudinally in the lateral direction of the vehicle body, such as... Figure 3 As shown, it is located on the lower side of the bottom part 500 of the vehicle body, that is, in the second area 200 outside the vehicle.

[0042] refer to Figure 2 The battery 210 can be disposed in front of the second transverse member 220. The upper rear end of the battery 210 can be fastened to the second transverse member 220. In other words, the battery 210 can have one end secured using a mounting bracket formed on the second transverse member 220 and located in the second region 200. Because the battery 210 can be disposed inside the vehicle, the second transverse member 220 disposed outside the vehicle can be mounted to penetrate the bottom portion 500 of the vehicle body to secure the battery 210 using the mounting bracket.

[0043] The rear seat 300 may also have a rear lower end fastened to the second lateral member 220. Because the rear seat 300 can be located inside the vehicle, the second lateral member 220, located outside the vehicle, can be mounted through the bottom portion 500 of the vehicle body and fastened to the rear seat 300 by mounting brackets to secure the rear seat 300. Specifically, the rear seat 300 may include a seat cushion, a seat back, and a seat frame, and the seat frame can be fastened to the second lateral member 220. The third lateral member 230 can be mounted to extend longitudinally to the left and right in the lateral direction of the vehicle body, such as... Figure 2 As shown, it is located on the upper side of the bottom portion 500 of the vehicle body, that is, inside the vehicle. (Reference) Figure 2 The third transverse member 230 can be disposed adjacent to the first region 100 in the second region 200.

[0044] One rear end of the fuel tank 110 can be fastened to the third transverse member 230. In other words, the fuel tank 110 can have one end secured using a mounting bracket formed on the third transverse member 230 and located in the first region 100. Because the fuel tank 110 can be located on the exterior of the vehicle, the third transverse member 230, located inside the vehicle, can be mounted through the bottom portion 500 of the vehicle body to secure the fuel tank 110 using the mounting bracket. The battery 210 can also have a front lower end secured to the third transverse member 230. In other words, the battery 210 can have one end secured using a mounting bracket formed on the third transverse member 230 and located in the second region 200.

[0045] The first cross member 120, the second cross member 220, and the third cross member 230 can all be fixedly installed to the underbody portion 500 using, for example, welding or the like, the first cross member 120 and the second cross member 220 can be fixedly installed to a lower surface of the underbody portion 500, and the third cross member 230 can be fixedly installed to an upper surface of the underbody portion 500.

[0046] In addition, the first cross member 120, the second cross member 220, and the third cross member 230 can not be installed at the same height and on the same surface, and at least some of the cross members can also be installed at the same height as each other, or all of the cross members can also be installed at different heights at each location according to the shape of the underbody portion 500.

[0047] Figure 3 is a rear view of a hybrid vehicle having an improved arrangement according to an exemplary embodiment of the present application. Referring to Figure 3 , the fuel tank 110 can be installed forward in the longitudinal direction of the vehicle body and longitudinally in the lateral direction of the vehicle body. In addition, the battery 210 is installed above the underbody portion 500 and is not shown in Figure 3 , the battery 210 can also be installed longitudinally in the lateral direction of the vehicle body behind the fuel tank 110. The hybrid vehicle having an improved arrangement according to another exemplary embodiment of the present application can further include a fuel tank strap 130 that surrounds at least a portion of the fuel tank 110 to fix the fuel tank 110 to the vehicle body.

[0048] As shown in Figure 3 , the fuel tank 110 can be supported by the vehicle body by the action of the fuel tank strap 130 together with the first cross member 120 and the third cross member 230. The fuel tank strap 130 surrounds at least a portion of the outer peripheral surface of the fuel tank 110 and can then be fastened to the vehicle body to support the fuel tank 110, and the fuel tank strap 130 can be formed of a steel plate having a predetermined thickness to increase rigidity. Therefore, a rib can also be formed in the cross section of the fuel tank strap 130. The fuel tank strap 130 can also be provided in pairs and installed spaced apart from each other along the width direction of the fuel tank 110 to support the fuel tank 110, but can also be installed along the longitudinal direction of the fuel tank 110 to support the fuel tank 110.

[0049] Referring to Figure 3 , the hybrid vehicle having an improved arrangement according to an exemplary embodiment of the present application can further include a pair of longitudinal members formed along the longitudinal direction of the vehicle body, and at least one of the first cross member, the second cross member, and the third cross member can be fastened to the pair of longitudinal members. As shown in Figure 3As illustrated, a pair of longitudinal members 410, 420 can be provided on both side ends with respect to the lateral direction of the vehicle body on the lower surface of the vehicle body bottom portion 500 and formed lengthwise along the longitudinal direction of the vehicle body to include the first region 100 and the second region 200.

[0050] The pair of longitudinal members 410, 420 can be fixedly installed on the lower surface of the vehicle body bottom portion 500 using a method such as welding. In particular, the vehicle body frame can be used as the longitudinal members. At this time, the battery 210 can be fixed to the vehicle body only by being fastened to the second lateral member 220 and the third lateral member 230 as described above, but can also be fixed to the vehicle body by being fastened to the pair of longitudinal members 410, 420.

[0051] In summary, the fuel tank 110 can be fixed to the first lateral member 120 provided on the outside of the vehicle using a mounting bracket, and can also be fixed to the third lateral member 230 provided on the inside of the vehicle and installed to pass through the vehicle body bottom portion 500 using a mounting bracket. In addition, the fuel tank strap 130 can more firmly fix the fuel tank 110 to the vehicle body.

[0052] The battery 210 can be fixed to the third lateral member 230 provided on the inside of the vehicle using a mounting bracket, and can also be fixed to the second lateral member 220 provided on the outside of the vehicle and installed to pass through the vehicle body bottom portion 500 using a mounting bracket. As a result, by fastening only both ends in the lateral direction of the battery, it is possible to stably fix and sufficiently support the battery having a relatively large weight. In addition, members that increase the weight of the vehicle body can be minimized.

[0053] In addition, the battery 210 can also be additionally fastened and fixed to the pair of longitudinal members 410, 420 provided on the outside of the vehicle and installed to pass through the vehicle body bottom portion 500 using a mounting bracket. The rear seat 300 can be fixed to the first lateral member 120 provided on the outside of the vehicle and installed to pass through the vehicle body bottom portion 500 using a mounting bracket, and fixed to the second lateral member 220 provided on the outside of the vehicle and installed to pass through the vehicle body bottom portion 500 using a mounting bracket.

[0054] The hybrid vehicle having an improved arrangement according to the exemplary embodiment of the present application can further include a rear suspension 240 formed along the lateral direction of the vehicle body and provided at at least one position between the second lateral member 220 and the battery 210 and between the third lateral member 230 and the battery 210.

[0055] Generally, a suspension device of a vehicle is classified into a front suspension and a rear suspension as a device for preventing vibrations or shocks received from a road surface during operation of the vehicle from being directly transmitted to a vehicle body, thereby preventing damage to the vehicle body or cargo and providing a comfortable ride. Physical characteristics of the rear suspension 240 can be formed of a rigid body having all structures that provide an elastic force.

[0056] The battery 210 according to another exemplary embodiment of the present application can also be directly fixed by the second cross member 220 and the third cross member 230, and mounted and fixed to the second region, in which the rear suspension 240 is interposed between the battery 210 and the second cross member 220, or the rear suspension 240 is interposed between the battery 210 and the third cross member 230. If the rear suspension 240 is applied, shocks transmitted to the battery 210 can be mitigated by absorbing the vehicle body vibrations transmitted to the second cross member 220 or the third cross member 230. Accordingly, improved vehicle crashworthiness can be ensured.

[0057] Figure 4 is a side sectional view of a hybrid vehicle having an improved arrangement structure according to an exemplary embodiment of the present application. When a high-voltage battery is installed at a lower side of a trunk, a capacity of the trunk for various purposes is reduced, and due to the reduction in the capacity of the trunk, a spare tire or the like can not be installed.

[0058] Reference Figure 4 According to an exemplary embodiment of the present application, the battery 210 can be installed at a position below the rear seat 300, which corresponds to a space not used in the hybrid vehicle, thereby maximizing a space of the trunk compared to a conventional structure in which the battery is installed in the trunk. As a result, marketability of the vehicle can be improved and convenience of a user can be increased. Further, by positioning the fuel tank 110 connected to the engine part in the first region 100, a coupling structure of the vehicle can be simplified.

[0059] Further, by forming a shape of a vehicle body bottom part 500 of the second region 200 to be concave downward, the rear seat can be prevented from being raised due to a structure in which the battery is inserted. The rear suspension 240 disposed between the second cross member 220 and the battery 210 can absorb front and rear direction vibrations of the vehicle, and the rear suspension 240 disposed between the third cross member 230 and the battery 210 can absorb vertical vibrations.

[0060] As described above, the present application provides a hybrid vehicle having an improved arrangement structure, which can dispose a battery 110 more forward than a fuel tank 210 in a space below a rear seat 300, thereby increasing a capacity of a trunk and ensuring an effective space in a vehicle interior space.

[0061] The foregoing detailed description has set forth various embodiments of the application via the use of a numbering scheme. Specific embodiments of the application have also been described otherwise herein with or without the use of numbers. The intent is that such description should not limit the application to particular embodiments described but should be construed to cover all implementations consistent with the description as disclosed herein and understood by those skilled in the art. Accordingly, the description is to be regarded as illustrative in nature, and not as restrictive.
