In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Figure 1 is a top view of a frame provided in some embodiments of the present application.

[0027] like Figure 1 As shown, in the first aspect, an embodiment of the present application provides a frame 10, including a first area 11, a second area 12 and a third area 13 distributed in sequence along the length direction of the frame 10, and the frame 10 is commonly used in pure electric vehicles and extended-range hybrid vehicles. In the pure electric vehicle application mode, at least part of the third area 13 can be used as storage space or passenger space; in the extended-range hybrid vehicle application mode, the third area 13 can be used to assemble the extended-range system 20.

[0028] Specifically, the first area 11, the second area 12 and the third area 13 are sequentially arranged along the length direction of the frame 10, and the length direction of the frame 10 is the length direction of the vehicle, that is, the front-rear direction of the vehicle. Among them, the first area 11 can be arranged near the front end of the vehicle, and the third area 13 can be arranged near the rear end of the vehicle, or the first area 11 can also be arranged near the rear end of the vehicle, and the third area 13 can be arranged near the front end of the vehicle, which is not limited in this embodiment. The third area 13 can be used as a general area. When the frame 10 is applied to a pure electric vehicle, at least part of the third area 13 can be used as a storage space or a passenger space. When the frame 10 is applied to an extended-range hybrid vehicle, the third area 13 can be used to assemble the extended-range system 20.

[0029] It should be noted that, in the pure electric vehicle application mode, at least part of the third area 13 can be directly used as storage space or passenger space, or, sheet metal or other structures can be set in the third area 13 to enclose storage space or passenger space. In the hybrid application mode, the range-extending system 20 can be directly installed on the frame 10 corresponding to the third area 13, or, the range-extending system 20 can be indirectly installed by setting a mounting structure in the third area 13, which is not limited in this embodiment. It can be understood that when the frame 10 is applied to a range-extended hybrid vehicle, the frame 10 can be applied to a pure electric vehicle by simply modifying the third area 13.

[0030] The frame 10 provided in the embodiment of the present application includes a first area 11, a second area 12 and a third area 13 distributed in sequence along the length direction of the frame 10. The frame 10 is commonly used in pure electric vehicles and extended-range hybrid vehicles. In the pure electric vehicle application mode, at least part of the third area 13 can be used as storage space or passenger space. In the extended-range hybrid vehicle application mode, the third area 13 can be used to assemble the extended-range system 20. Therefore, by connecting the frame 10 in the pure electric vehicle application mode with the suspension of the chassis 100, or connecting the frame 10 in the extended-range hybrid vehicle application mode with the suspension of the chassis 100, a chassis 100 for a pure electric vehicle or a chassis 100 for an extended-range hybrid vehicle can be assembled, so that the frame 10 is commonly used in pure electric vehicles and extended-range hybrid vehicles, thereby improving the versatility of the vehicle chassis 100 and reducing production costs.

[0031] In addition, by using at least part of the third area 13 as a storage space or a passenger space in the pure electric application mode, and accommodating the range-extending system 20 in the range-extending hybrid vehicle application mode through the third area 13, the space of the frame 10 can be reasonably arranged, thereby improving the space utilization of the frame 10. Moreover, in the range-extending hybrid vehicle application mode, the range-extending system 20 is integrated in the third area 13, thereby shortening the length of the intake duct and the exhaust duct in the range-extending system 20, making the structure of the range-extending system 20 more compact, thereby further improving the space utilization.

[0032] It should be noted that the vehicle frame 10 may include two longitudinal beams 14 and a plurality of cross beams 15. The two longitudinal beams 14 may be arranged at intervals relative to each other along the width direction of the vehicle frame 10. The plurality of cross beams 15 may be arranged at intervals in sequence along the length direction of the vehicle frame 10. The cross beam 15 may be located between the two longitudinal beams 14, and its two ends may be connected to the two longitudinal beams 14, respectively. In the length direction of the vehicle frame 10, different positions of the longitudinal beams 14 may correspond to the first area 11, the second area 12, and the third area 13, respectively. For example, the longitudinal beam 14 may include a first portion, a second portion, and a third portion arranged in sequence along the length direction of the vehicle. The first portion may correspond to the first area 11, the second portion corresponds to the second area 12, and the third portion may correspond to the third area 13. Multiple beams 15 may correspond to the first area 11, the second area 12 and the third area 13 respectively; illustratively, the number of beams 15 may be two, one of which is located at the junction of the first area 11 and the second area 12, corresponding to the first area 11 and the second area 12 respectively, and the other beam 15 is located at the junction of the second area 12 and the third area 13, corresponding to the second area 12 and the third area 13 respectively.

[0033] Figure 2 is another top view of the frame provided in some embodiments of the present application.

[0034] like Figure 2 As shown, in some embodiments, the frame 10 includes a frame body 16. In the extended-range hybrid vehicle application mode, the frame 10 also includes an extended-range mounting structure 17 located in the third area 13. The extended-range mounting structure 17 includes a mounting beam 171 connected to the frame body 16. The projection of the mounting beam 171 on the frame body 16 along the first direction X extends along the second direction Y. The third area 13 is divided by the mounting beam 171 into a first sub-area and a second sub-area distributed along the third direction Z. The first sub-area is used to set the range extender of the extended-range system 20, and the second sub-area is used to set the fuel tank of the extended-range system 20. The first direction X, the second direction Y and the third direction Z are arranged to intersect each other.

[0035] The first direction X may be a height direction of the frame 10 , the second direction Y may be any one of a length direction and a width direction of the frame 10 , and the third direction Z may be the other direction.

[0036] In these embodiments, in the extended-range hybrid vehicle application mode, by setting the extended-range mounting structure 17 in the third area 13, the extended-range system 20 can be installed on the frame 10 corresponding to the third area 13 through the extended-range mounting structure 17, and the installation stability of the extended-range system 20 can be improved. Specifically, the extended-range mounting structure 17 includes a mounting beam 171 connected to the frame body 16, and the projection of the mounting beam 171 on the frame body 16 along the first direction X extends along the second direction Y, that is, the mounting beam 171 can extend approximately along the second direction Y, which can separate the third area 13 into a first sub-area and a second sub-area, so that the first sub-area and the second sub-area are distributed along the third direction Z, and the mounting beam 171 is located between the first sub-area and the second sub-area. Among them, the first sub-area is used to set the range extender of the extended-range system 20, and the second sub-area is used to set the fuel tank of the extended-range system 20, so that the space of the third area 13 can be reasonably utilized, and the space utilization rate can be further improved.

[0037] In some optional embodiments, the range-extended mounting structure 17 and the vehicle frame body 16 may be fastened and connected by bolts, or may be connected by welding or other methods, which is not limited in this embodiment.

[0038] In some optional embodiments, the range-extending mounting structure 17 further includes a plurality of suspensions. In the range-extending system 20 , structures such as the range extender and the fuel tank may be mounted on the vehicle frame 10 via the suspensions, thereby improving the stability of the range-extending system 20 .

[0039] In some optional embodiments, the mounting beam 171 may be connected to a suspension portion for mounting the range extender, thereby improving the installation stability of the range extender.

[0040] Figure 3 is a top view of a chassis provided in some embodiments of the present application.

[0041] like Figure 3 As shown, in the second aspect, the embodiment of the present application provides a chassis 100, including a chassis body 30 and any of the above frames 10, wherein the frame body 16 of the frame 10 is connected to the chassis body 30. The chassis 100 provided in the embodiment of the present application has the technical effects of the technical solution of the frame 10 in any of the above embodiments, and the explanation of the structures and terms that are the same or corresponding to the above embodiments will not be repeated here.

[0042] It should be noted that when the chassis 100 includes the frame 10 in the pure electric vehicle application mode, the chassis 100 can be used as the chassis 100 of the pure electric vehicle, and when the chassis 100 includes the frame 10 in the extended-range hybrid vehicle application mode, the chassis 100 can be used as the chassis 100 of the extended-range hybrid vehicle.

[0043] In some embodiments, the third area 13 is disposed near the rear end of the chassis body 30 .

[0044] In these embodiments, the third area 13 is arranged near the rear end of the chassis body 30. Therefore, when the chassis 100 includes the frame 10 in the extended-range hybrid application mode, the range extender system 20 is installed in the third area 13, that is, the range extender system 20 is integrated and distributed near the rear end of the chassis body 30, so that the exhaust pipe of the exhaust unit in the range extender system 20 is close to the rear end of the chassis body 30 for exhaust, thereby reducing the impact of the noise generated by the exhaust on the passengers in the passenger compartment.

[0045] Figure 4 It is a partial enlarged view of the chassis provided in some embodiments of the present application.

[0046] See also Figure 3 and Figure 4 In some embodiments, the chassis body 30 includes a first suspension assembly 31 and a second suspension assembly 32 , and at least one of the first suspension assembly 31 and the second suspension assembly 32 includes a leaf spring 33 and two suspensions 34 .

[0047] One of the first suspension assembly 31 and the second suspension assembly 32 can be arranged near the front wheel of the chassis body 30, and the other can be arranged near the rear wheel of the chassis body 30, which is not limited in this embodiment. At least one of the first suspension assembly 31 and the second suspension assembly 32 includes a leaf spring 33 and two suspensions 34, and the two suspensions 34 can be arranged relatively spaced along the width direction of the chassis 100, and can be connected to the two front wheels or the two rear wheels of the chassis body 30 respectively. The leaf spring 33 can be connected between the two suspensions 34, and can play an elastic buffering role and a shock absorbing role, with a simple structure and high reliability. In addition, by arranging the leaf spring 33 in the first suspension assembly 31 and / or the second suspension assembly 32, compared with a coil spring, a torsion bar spring, an air spring, etc., the height of the shock absorber tower package in the suspension 34 can be reduced, so that the shock absorber 343 can be installed on the longitudinal beam bracket of the frame 10.

[0048] It should be noted that when the first suspension assembly 31 includes a leaf spring 33 and two suspensions 34 , the second suspension assembly 32 may include any type of suspension 34 such as a McPherson suspension 34 , a multi-link suspension 34 , a torsion beam suspension 34 , etc., and this embodiment does not limit this.

[0049] In some optional embodiments, when the first suspension assembly 31 includes a leaf spring 33 and two suspensions 34, the second suspension assembly 32 may include a trailing arm suspension 34, thereby improving the comfort of the chassis 100. Preferably, the second suspension assembly 32 is disposed close to the rear wheels of the chassis body 30, thereby improving the comfort of the vehicle.

[0050] Please continue reading Figure 4 In some embodiments, the suspension 34 includes an upper swing arm 341, a lower swing arm 342, a shock absorber 343, a steering knuckle and a wheel hub. The upper swing arm 341 is arranged along the height direction of the chassis 100 close to the wheel center of the chassis body 30 to form a low-mounted double wishbone suspension 34, thereby further reducing the height of the shock absorber tower package and improving the handling, stability and comfort of the wheel.

[0051] Figure 5 This is a bottom view of a vehicle provided in some embodiments of the present application.

[0052] like Figure 5 As shown, in the third aspect, the embodiment of the present application further provides a vehicle, comprising any of the above chassis 100, power battery 200 and thermal management system; the power battery 200 is arranged on the frame 10 of the chassis 100; the thermal management system is arranged on the frame 10. The vehicle provided by the embodiment of the present application has the technical effect of the technical solution of the chassis 100 in any of the above embodiments, and the structures identical or corresponding to the above embodiments and the explanation of terms are not repeated here.

[0053] The power battery 200 is used to provide power for the wheels, and the thermal management system can be used to achieve thermal management of various components in the vehicle, and the thermal management system can also include an onboard air conditioner to achieve cooling and heating of the vehicle. Exemplarily, part of the thermal management system can extend in a direction close to the power battery 200 to exchange heat with the power battery 200.

[0054] It should be noted that when the chassis 100 of the vehicle includes the frame 10 in the extended-range hybrid vehicle application mode, the vehicle also includes a range-extending system 20, which may include a range extender, a fuel tank, an air intake unit and an exhaust unit. The range extender may include an engine, a generator and a generator controller. The range-extending system 20 may be electrically connected to the power battery 200. During the operation of the range-extending system 20, the power battery 200 may first power the generator in the range extender, so that the generator runs and drives the engine to start, thereby powering the vehicle drive system or charging the power battery 200 through the engine. The air intake unit may be connected to the air intake of the engine to deliver air to the inside of the engine. The exhaust unit is connected to the exhaust port of the engine of the range extender, which may discharge the exhaust gas generated during the operation of the engine.

[0055] Please continue reading Figure 5 In some embodiments, part of the thermal management system is located in the first area 11 of the frame 10 , at least for heat exchange with the range extender system 20 , and the power battery 200 is located in the second area 12 of the frame 10 .

[0056] In these embodiments, the power battery 200 is arranged in the second area 12, that is, the power battery 200 is arranged close to the middle area of ​​the vehicle, so that the center of gravity of the vehicle can be close to the middle area of ​​the vehicle to improve the stability and safety of the vehicle. Part of the thermal management system is located in the first area 11 of the frame 10. Specifically, the thermal management module includes a thermal management body and a heat exchange pipe connected to the thermal management body. The thermal management body may include components such as a compressor and a heat pump. The thermal management body is arranged in the first area 11, and at least part of the heat exchange pipe can extend to the second area 12 for heat exchange with the power battery 200. In addition, when the chassis 100 includes the frame 10 in the extended-range hybrid vehicle application mode, part of the heat exchange pipe extends to the second area 12 for heat exchange with the power battery 200, and part of the heat exchange pipe can pass through the second area 12 and extend to the third area 13 for heat exchange with the extended-range system 20.

[0057] It can be understood that when the chassis 100 includes the frame 10 in the extended-range hybrid vehicle application mode, the range extender system 20 is arranged in the third area 13, the thermal management body of the thermal management system is arranged in the first area 11, and the power battery 200 is arranged in the second area 12, which can make the weight distribution of the vehicle as uniform as possible, thereby improving the stability and safety of the vehicle.

[0058] Figure 6 It is a schematic diagram of the structure of a frame provided in some embodiments of the present application.

[0059] like Figure 5 and Figure 6 As shown, in some embodiments, the frame 10 includes two longitudinal beams 14 spaced apart along the width direction of the chassis 100 and two cross beams 15 spaced apart along the length direction of the chassis 100. The cross beam 15 is located between the two longitudinal beams 14 and respectively connects the two longitudinal beams 14. The two longitudinal beams 14 and the two cross beams 15 jointly define a receiving space 18 located in the second area 12. At least part of the power battery 200 is located in the receiving space 18 and is connected to at least one of the longitudinal beams 14 and the cross beams 15.

[0060] In these embodiments, the two longitudinal beams 14 are spaced apart along the width direction of the chassis 100, the two cross beams 15 are spaced apart along the length direction of the chassis 100, the two cross beams 15 are located between the two longitudinal beams 14, and the two ends of the cross beams 15 are respectively connected to the two longitudinal beams 14, so that the two cross beams 15 and the two longitudinal beams 14 can enclose a accommodating space 18, and at least part of the power battery 200 is located in the accommodating space 18. Compared with suspending the power battery 200 below the longitudinal beams 14 and / or the cross beams 15, the height of the chassis 100 can be lowered and the size of the passenger compartment along the height direction of the chassis 100 can be increased when the distance between the power battery 200 and the ground is constant, thereby improving the comfort of the vehicle.

[0061] It should be noted that at least part of the power battery 200 is located in the accommodating space 18 , therefore, the two cross beams 15 can be located on both sides of the power battery 200 along the length direction of the chassis 100 , and the two longitudinal beams 14 can be located on both sides of the power battery 200 along the width direction of the chassis 100 .

[0062] In some optional embodiments, the power battery 200 may include a battery module and a battery box. The battery box may include a top wall and a bottom wall. The top wall and the bottom wall are respectively connected to two cross beams 15 and two longitudinal beams 14, so as to enclose together with the two cross beams 15 and the two longitudinal beams 14 to form a space for accommodating the battery module. Therefore, there is no need to provide additional side walls in the battery box, which can reduce the volume of the power battery 200, or increase the space for accommodating the battery module, that is, increase the battery life of the power battery 200.

[0063] In other optional embodiments, the vehicle also includes a floor arranged above the frame 10 of the chassis 100, the power battery 200 includes a battery module and a battery box, the battery box may include a bottom wall, and the bottom wall is respectively connected to the two cross beams 15 and the two longitudinal beams 14, so that the two cross beams 15, the two longitudinal beams 14 and the floor above the frame 10 can be enclosed together with the bottom wall to form a space for accommodating the battery module, without the need to additionally arrange side walls and top walls in the battery box, which can further reduce the volume of the power battery 200, or further increase the space for accommodating the battery module, thereby increasing the endurance of the power battery 200.

[0064] Please continue reading Figure 6 In some embodiments, the frame 10 further includes a partition beam 19, which is detachably disposed in the accommodating space 18. The accommodating space 18 is divided by the partition beam 19 into a first chamber 181 and a second chamber 182 distributed on one side of the first chamber 181. The power battery 200 is disposed in the first chamber 181 and connected to the partition beam 19.

[0065] It can be understood that in an extended-range hybrid vehicle, since the range-extended system 20 can improve the vehicle's endurance, the capacity of the power battery 200 can be reduced accordingly, that is, the volume of the power battery 200 can be reduced accordingly to reduce the vehicle load. In other words, the capacity and volume of the power battery 200 of a pure electric vehicle are greater than the capacity and volume of the power battery 200 of an extended-range hybrid vehicle. Since the frame 10 of the chassis 100 is common to extended-range hybrid vehicles and pure electric vehicles, the size of the accommodating space 18 formed by the longitudinal beam 14 and the transverse beam 15 of the frame 10 is usually adapted to the volume of the power battery 200 of a pure electric vehicle, that is, the size of the accommodating space 18 is usually greater than the size of the power battery 200 of an extended-range hybrid vehicle.

[0066] In view of this, in these embodiments, by detachably arranging the partition beam 19 in the accommodation space 18, when the chassis 100 is assembled as a pure electric vehicle, by separating the partition beam 19 from the frame 10, the accommodation space 18 is sufficient to accommodate the larger capacity power battery 200 of the pure electric vehicle; when the chassis 100 is assembled as an extended-range hybrid vehicle, by installing the partition beam 19 in the accommodation space 18, the accommodation space 18 is divided into a first chamber 181 and a second chamber 182, so that the smaller capacity power battery 200 of the extended-range hybrid vehicle is located in the first chamber 181 and connected to the partition beam 19, the stability of the power battery 200 of the extended-range hybrid vehicle can be improved. At the same time, the second chamber 182 can be used to accommodate other components of the vehicle to improve space utilization.

[0067] In some embodiments, the vehicle further includes an upper body detachably connected to the chassis 100 .

[0068] In these embodiments, the chassis 100 is detachably connected to the upper body. Therefore, when the chassis 100 includes the frame 10 in the pure electric vehicle application mode, the upper body corresponding to the pure electric vehicle can be connected to the chassis 100. When the chassis 100 includes the frame 10 in the extended-range hybrid vehicle application mode, the upper body corresponding to the extended-range hybrid vehicle can be connected to the chassis 100, thereby improving the versatility of various components in the vehicle.

[0069] The above is only a specific implementation of the present application.
