Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle. Background Art

[0002] As the range-extending technology matures, the range-extending vehicles are being used in more and more models. The range-extending technology is currently widely used in small cars and medium-to-large SUVs with large front cabins. Models with large front cabins have enough space to install engines, generators or drive motors. However, in the relevant technology, models with small front cabins such as vans or small trucks cannot install engines, generators or drive motors, and the range-extending technology is difficult to apply to models with small front cabins such as vans or small trucks. Summary of the invention

[0003] The present application provides a vehicle that solves the technical problem that the range-extended technology is difficult to apply to vehicles with a smaller front cabin.

[0004] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0005] An embodiment of the present application provides a vehicle, which includes a frame, an engine, a generator, a drive motor and a first seat. The engine, the generator, the battery pack and the drive motor are all arranged on the frame, the engine is connected to the generator, the battery pack is respectively connected to the generator and the drive motor, and the first seat is arranged on the frame. Along the front and rear direction of the vehicle, the engine, the generator, the battery pack and the drive motor are arranged in sequence. Along the up and down direction of the vehicle, the first seat is located above the engine, wherein the axial direction of the drive motor is parallel to the left and right direction of the vehicle. The vehicle also includes a drive motor controller. Along the left and right direction of the vehicle, the drive motor controller and the drive motor are arranged relative to each other.

[0006] Along the front and rear directions of the vehicle, the engine, generator, battery pack and drive motor are arranged relatively to each other. Along the up and down directions of the vehicle, the first seat is located above the engine, which allows sufficient space for the engine to be placed, so that models with smaller front engine cabins can also use extended-range models, solving the technical problem that models with smaller front engine cabins cannot be used for extended-range technology, and expanding the scope of application of extended-range technology.

[0007] Optionally, the generator is configured as a low-speed generator, the rotation speed of the low-speed generator is from 0 to 6000 revolutions per minute, the vehicle further includes a torsional damper, and the engine is connected to the low-speed generator via the torsional damper.

[0008] The engine and low-speed electric motor are connected through a torsional damper, which reduces the space occupied by components in the front and rear directions of the vehicle while meeting the high-power operation of the generator, so that models with smaller front cabins can also use extended-range technology.

[0009] Optionally, the axial direction of the generator is in the same direction as the front-rear direction of the vehicle, and the vehicle also includes a generator controller. Along the front-rear direction of the vehicle, the torsional damper, the generator and the generator controller are relatively arranged and arranged in sequence.

[0010] Along the front-to-back direction of the vehicle, the torsional damper, the generator and the generator controller are relatively arranged and arranged in sequence, reducing the space occupied by the generator controller in the front-to-back direction of the vehicle, so that models with smaller front engine compartments can use extended-range technology.

[0011] Optionally, the vehicle further includes a charging and distribution device, which is connected to the generator controller and the drive motor controller respectively, and the charging and distribution device and the battery pack are arranged opposite to each other along the left and right directions of the vehicle.

[0012] Along the left and right directions of the vehicle, the charging and distributing device is arranged opposite to the battery pack. This can effectively improve the space utilization of the vehicle in the front and rear directions, reduce the space occupied by the charging and distributing device in the front and rear directions of the vehicle, and make the extended-range technology applicable to models with smaller front cabins, thus expanding the scope of models applicable to the extended-range technology.

[0013] Optionally, the vehicle further includes a battery control system, which is arranged opposite to the battery pack along the up and down direction of the vehicle.

[0014] Since vehicles such as vans or trucks have a large space in the up and down directions and a small front engine room, the battery control system and the battery pack are arranged relative to each other along the up and down directions of the vehicle. This can fully and effectively utilize the up and down space of the vehicle, reduce the space occupancy in the up and down directions of the vehicle, and improve the space utilization rate in the front and rear directions of the vehicle, so that vehicles with smaller front engine rooms can be used for extended-range technology, expanding the scope of vehicles to which extended-range technology can be applied.

[0015] Optionally, the battery pack includes a first part and a second part. Along the front-to-rear direction of the vehicle, the first part is located in front of the second part, and along the up-down direction of the vehicle, the battery control system is arranged on the upper side of the second part.

[0016] The battery control system is arranged on the upper side of the second part, which can reasonably utilize the upper space of the first part of the battery pack, thereby further reducing the space occupied by components in the front cabin or under the first seat, so that there is enough space under the first seat to set up components such as the engine or generator.

[0017] Optionally, the engine has multiple cylinders, the length direction of the engine is parallel to the front-rear direction of the vehicle, and the axis of the cylinder has an angle with the up-down direction of the vehicle, and the angle ranges from 45 degrees to 65 degrees.

[0018] The axis of the cylinder has an angle with the up-down direction of the vehicle, and the angle ranges from 45 degrees to 65 degrees, which can enable the engine to reasonably occupy the space in the up-down direction of the vehicle, reduce the space occupied in the front-rear direction of the vehicle, and make the arrangement of internal components of the vehicle more reasonable.

[0019] Optionally, the vehicle also includes a second seat, which is arranged on the frame and is arranged opposite to the battery pack along the up and down direction of the vehicle.

[0020] Along the up and down direction of the vehicle, the second seat is arranged opposite to the battery pack, which can make full use of the space inside the vehicle and avoid the battery pack occupying other important areas such as the trunk or front space. This allows models with smaller front cabins to also be suitable for extended-range technology, expanding the scope of application of models with extended-range technology.

[0021] Optionally, the vehicle further includes a body in white, wherein a front engine compartment and a cockpit are provided in the body in white, the body in white has a dash panel, the dash panel is arranged between the front engine compartment and the cockpit, and the engine is located at the rear side of the dash panel and at the lower side of the cockpit.

[0022] The engine is located behind the front panel and under the cockpit. When the vehicle collides, the crumple space of the front cabin is retained. In the event of a head-on collision, this space can absorb part of the impact energy, reduce the impact on the occupants, and improve the safety performance of the vehicle users. In addition, the engine is set under the cockpit, which can save space in the front cabin, making the extended-range technology applicable to models with smaller front cabins, expanding the applicable range of models of extended-range technology.

[0023] Optionally, the engine, generator, battery pack and drive motor are relatively arranged along the front-rear direction of the vehicle.

[0024] The engine, generator, battery pack and drive motor are arranged relatively along the front and rear directions of the vehicle, which can make the weight distribution of the power system in the vehicle more balanced, help lower the height of the vehicle's center of gravity, and improve the vehicle's handling and stability.

[0040] As the range-extending technology matures, the range-extending vehicles are being used in more and more models. The range-extending technology is currently widely used in small cars and medium-to-large SUVs with large front cabins. Models with large front cabins have enough space to install engines, generators or drive motors, etc., which can meet the needs of range extender installation.

[0041] For models such as vans or small trucks, the driver's driving vision, cargo carrying capacity and manufacturing costs need to be comprehensively considered, and the front cabin of such models is usually designed to be smaller.

[0042] Therefore, in the relevant technology, vehicles with smaller front cabins, such as vans or small trucks, cannot install engines, generators or drive motors, and range-extended technology is difficult to apply to vehicles with smaller front cabins, such as vans or small trucks.

[0043] In view of this, in order to solve the technical problem that the range-extended technology is difficult to apply to vehicles with a small front cabin such as vans or small trucks, some embodiments of the present application provide a vehicle, the vehicle including a frame, an engine, a generator, a drive motor and a first seat.

[0044] The engine, generator, battery pack and drive motor are all arranged on the frame, the engine is connected to the generator, the battery pack is connected to the generator and the drive motor respectively, the first seat is arranged on the frame, along the front and rear direction of the vehicle, the engine, generator, battery pack and drive motor are arranged in sequence, along the up and down direction of the vehicle, the first seat is located above the engine, wherein the axial direction of the drive motor is parallel to the left and right direction of the vehicle, the vehicle also includes a drive motor controller, along the left and right direction of the vehicle, the drive motor controller and the drive motor are arranged relative to each other.

[0045] In the above scheme, the first seat is located above the engine along the up and down direction of the vehicle, and the engine can be set below the first seat, saving space in the front cabin and improving the space utilization under the first seat of the vehicle, so that the extended-range technology can be applied to vehicles with a smaller front cabin.

[0046] For the convenience of description, the following embodiments are described by taking a vehicle 100 according to an embodiment of the present application as an example.

[0047] Please refer to Figures 1 to 6 , Figure 1 To show the structure of the chassis of the vehicle 100; Figure 2 A schematic diagram of the structure of a vehicle 100 provided in one embodiment of the present application; Figure 3 for Figure 2 A top view of Figure 4 A schematic diagram of the structure of a vehicle 100 provided in one embodiment of the present application; Figure 5 The connection relationship between the engine 120, the generator 130, the torsional vibration damper 170 and the generator controller 190 is shown; Figure 6 The relationship between the battery pack 140 and the battery control system 240 is shown.

[0048] In the embodiment of the present application, the vehicle 100 includes a frame 110, an engine 120, a generator 130, a drive motor 150 and a first seat 160. The engine 120, the generator 130, the battery pack 140 and the drive motor 150 are all arranged on the frame 110. The engine 120 is connected to the generator 130. The battery pack 140 is respectively connected to the generator 130 and the drive motor 150. The first seat 160 is arranged on the frame 110. Along the front-to-back direction X of the vehicle 100, the engine 120, the generator 130, the battery pack 140 and the drive motor 150 are arranged in sequence. Along the up-down direction Z of the vehicle 100, the first seat 160 is located above the engine 120. The axial direction of the drive motor 150 is parallel to the left-right direction Y of the vehicle 100. The vehicle 100 also includes a drive motor controller 210. Along the left-right direction Y of the vehicle 100, the drive motor controller 210 is arranged opposite to the drive motor 150.

[0049] The vehicle 100 includes a frame 110, an engine 120, a generator 130, a drive motor 150 and a first seat 160. It is understood that the frame 110 serves as a carrier of the vehicle 100, the engine 120, the generator 130, the battery pack 140 and the drive motor 150 are all arranged on the frame 110, and the first seat 160 is also arranged on the frame 110. The engine 120 is connected to the generator 130, and the generator 130 is connected to the battery pack 140. The engine 120 provides a power source for the generator 130. When the power of the battery pack 140 is lower than a certain threshold, the engine 120 drives the generator 130 to generate electricity, and the generator 130 transmits the generated electric energy to the battery pack 140. The battery pack 140 is connected to the drive motor 150, and the battery pack 140 can transmit the electric energy stored in itself or the electric energy generated by the generator 130 to the drive motor 150, so that the drive motor 150 can drive the vehicle 100.

[0050] Compared with traditional cars, if the engine 120 of the traditional car is set in the front cabin 260 or under the first seat 160, it is necessary to set a transmission shaft between the drive wheel axle 280 and the engine 120 to drive the vehicle 100. Since the extended-range vehicle uses the drive motor 150 to drive the vehicle 100 forward instead of the engine 120, the engine 120 is mainly used to drive the generator 130 to power the drive motor 150 or the battery pack 140. Therefore, the battery pack 140 can be set between the engine 120 and the drive motor 150 without setting a transmission shaft, thereby saving the size of the internal space of the vehicle 100 in the front and rear direction X, and improving the space utilization inside the vehicle 100.

[0051] Along the front-to-rear direction X of the vehicle 100, the engine 120, the generator 130, the battery pack 140 and the drive motor 150 are arranged in sequence. On the one hand, the sequentially arranged components make the power transmission path more direct and smooth, reducing the loss of energy during the transmission process. The power generated by the engine 120 can be directly transmitted to the generator 130, and the generator 130 then transmits the electrical energy to the battery pack 140. The entire power transmission process is efficient and stable. On the other hand, by reasonably arranging the weight of each component, a balanced distribution of the front and rear weight of the vehicle 100 can be achieved, which helps to improve the handling stability and driving safety of the vehicle 100 and reduce the risk of loss of control or rollover of the vehicle 100 due to uneven weight distribution.

[0052] The axial direction of the drive motor 150 is parallel to the left-right direction Y of the vehicle 100 . The vehicle 100 further includes a drive motor controller 210 . Along the left-right direction Y of the vehicle 100 , the drive motor controller 210 is disposed opposite to the drive motor 150 .

[0053] In the extended-range vehicle 100, the drive motor 150 is the power source that directly drives the vehicle 100. The drive motor 150 is power-connected to the drive axle 280. The drive motor 150 and the drive axle 280 can be connected through a transmission member 270. The axial direction of the drive motor 150 is actually also the axial direction of the rotor 200 of the drive motor. The axial direction of the rotor 200 of the drive motor is in the same direction as the left-right direction Y of the vehicle 100, which can reduce the complexity of the transmission member 270. It can be understood that when the axial direction of the rotor 200 of the drive motor is in the same direction as the left-right direction Y of the vehicle 100, the axial direction of the rotor 200 of the drive motor is also parallel to the axis of the drive axle 280 of the vehicle 100, and the transmission between the two parallel components can be directly transmitted using a simple gear mechanism group. If the axial direction of the rotor 200 of the drive motor is not in the same direction as the left-right direction Y of the vehicle 100, for example, the axial direction of the rotor 200 of the drive motor is perpendicular to the left-right direction Y of the vehicle 100, then it is necessary to add a transmission component such as a universal joint that can change the transmission direction, which will increase the complexity of the transmission between the drive motor 150 and the drive wheel axle 280.

[0054] Along the left-right direction Y of the vehicle 100, the drive motor controller 210 is arranged opposite to the drive motor 150, that is, along the left-right direction Y of the vehicle 100, the projections of the drive motor controller 210 and the drive motor 150 at least partially overlap, reducing the occupancy of the transmission member 270 in the front-rear direction X of the vehicle 100. Since the axial length of the rotor 200 of the drive motor is relatively long, the axial direction of the rotor 200 of the drive motor is aligned with the left-right direction Y of the vehicle 100 instead of the length direction, which can reduce the occupancy of the vehicle 100 in the length direction, so that the vehicle with a smaller front cabin 260 can be suitable for the extended range technology. Exemplarily, the transmission member 270 can be a gear set.

[0055] The vehicle 100 also includes a drive motor controller 210. The drive motor controller 210 is arranged opposite to the drive motor 150 along the left-right direction Y of the vehicle 100. That is, along the left-right direction Y of the vehicle 100, the projections of the drive motor controller 210 and the drive motor 150 at least partially overlap. The drive motor 150 and the drive motor controller 210 can jointly occupy the space of the vehicle 100 in the front-to-back direction X, thereby improving the space utilization of the vehicle 100 in the front-to-back direction X and reducing the space occupied in the front-to-back direction X of the vehicle 100, thereby enabling vehicles with a smaller front engine compartment 260 to also be applicable to the extended-range technology, thereby expanding the scope of application of the extended-range technology.

[0056] Since the drive motor controller 210 and the drive motor 150 are arranged relative to each other, the electrical connection line between them can be shorter and more direct, which helps to reduce the complexity and length of the line, thereby reducing the line resistance and energy loss and improving the energy transmission efficiency. At the same time, the simplified line connection also helps to reduce potential failure points and improve the reliability of the system.

[0057] The relatively arranged layout makes the relative position between the drive motor controller 210 and the drive motor 150 more clear and fixed, which can easily locate the corresponding components during maintenance and improve maintenance efficiency. At the same time, this layout also helps to reduce misoperation during maintenance and ensure maintenance safety.

[0058] Compared with vehicles with a smaller front cabin 260, such as trucks and vans, there is often a larger space below the first seat 160. Therefore, along the up-down direction Z of the vehicle 100, the first seat 160 is located above the engine 120. That is to say, the engine 120 is arranged below the first seat 160, which is actually also below the cockpit. This allows the engine 120 to have enough space to be placed, and thus vehicles with a smaller front cabin 260 can also use the extended-range vehicle, solving the technical problem that vehicles with a smaller front cabin 260 cannot be applied to the extended-range technology, and expanding the scope of application of the extended-range technology. Moreover, since the engine 120 is arranged below the first seat 160, but not in the front cabin 260, the risk of the engine 120 invading the cockpit in the event of a collision is greatly reduced, which helps to protect passengers from secondary injuries and improve the overall safety performance of the vehicle 100. In addition, the engine 120 is arranged below the first seat 160 , which can also lower the center of gravity of the vehicle 100 , make the layout of components inside the vehicle 100 more reasonable, improve the driving stability and reliability of the vehicle 100 , and enhance the anti-rollover capability of the vehicle 100 .

[0059] In some embodiments, a generator 130 and a generator controller 190 may also be disposed below the first seat 160 .

[0060] Please refer to Figures 1 to 6 In this embodiment, the generator 130 is constructed as a low-speed generator 130, and the rotation speed of the generator 130 is 0 to 6000 revolutions per minute. The vehicle 100 also includes a torsional damper 170, and the engine 120 is connected to the low-speed engine 120 through the torsional damper 170.

[0061] The low-speed generator 130 can more effectively convert fuel into electrical energy by reducing the rotation speed, thereby improving the efficiency of power generation and thereby improving the overall endurance of the vehicle 100. Since the rotation speed of the low-speed generator 130 is relatively low, the mechanical wear of the low-speed generator 130 is relatively small, thereby extending the service life of the equipment.

[0062] In conventional models, the generator 130 usually adopts a high-speed generator 130, and under high-power conditions, the rotation speed of the engine 120 is difficult to adapt to the rotation speed of the high-speed generator 130, and a gear set that can be used to adjust the rotation speed needs to be provided between the engine 120 and the high-speed generator 130, and the gear set occupies a large space in the front-to-back direction X of the vehicle 100. In the embodiment of the present application, the high-speed generator 130 in the conventional model is replaced with a low-speed generator 130, and the engine 120 and the generator 130 are connected through a torsional damper 170. Under the condition that the high-power operation of the generator 130 can be met, the space occupied by the components in the front-to-back direction X of the vehicle 100 is reduced, so that the vehicle model with a smaller front engine compartment 260 can also be applied to the extended-range technology.

[0063] The torsional damper 170 can more effectively absorb and dissipate torsional vibrations generated by the operation of the engine 120 or external impacts, thereby reducing the vibration level of the equipment, reducing errors and interference caused by vibration, and improving the stability of the operation of the vehicle 100.

[0064] Moreover, the engine 120 is connected to the low-speed generator via the torsional damper 170, which can provide the driver with a smoother and more comfortable driving experience by reducing torque rotation. This is especially important for vehicles with large vibrations such as vans and trucks.

[0065] Please refer to Figures 1 to 6 In this embodiment, the axial direction of the generator 130 is in the same direction as the front-rear direction X of the vehicle 100. The vehicle 100 also includes a generator controller 190. Along the front-rear direction X of the vehicle 100, the torsional damper 170, the generator 130 and the generator controller 190 are relatively arranged and arranged in sequence.

[0066] The axial direction of the generator 130, which is actually also the axial direction of the rotor 180 of the generator 130, is along the front-rear direction X of the vehicle 100. The axial direction of the generator 130 is in the same direction as the front-rear direction X of the vehicle 100. That is to say, the power input end of the generator 130 is in the front-rear direction X of the vehicle 100, and the power output end of the engine 120 can also be in the front-rear direction X of the vehicle 100. When the axial direction of the rotor 180 of the generator 130 is in the same direction as the front-rear direction X of the vehicle 100, the power transmission path is more direct, which means that the energy loss when the power is transmitted from the engine 120 to the generator 130 will be reduced.

[0067] Moreover, the axial direction of the rotor 180 of the generator 130 is in the same direction as the front-rear direction X of the vehicle 100, so the power transmission between the engine 120 and the generator 130 is more direct, reducing the complexity of the transmission part 270, thereby reducing the internal space occupied by the vehicle 100, and making the engine 120, the generator 130 and other related components arranged in a more compact manner, which can further save the internal space of the vehicle 100 and enable vehicles with a smaller front engine compartment 260 to also apply the extended-range technology.

[0068] Along the front-to-back direction X of the vehicle 100, the torsion damper 170, the generator 130 and the generator controller 190 are arranged relative to each other and arranged in sequence, that is, along the front-to-back direction X of the vehicle 100, the projections of the torsion damper 170, the generator 130 and the generator controller 190 at least partially overlap. Exemplarily, the length direction of the generator controller 190 can be arranged parallel to the left-right direction Y of the vehicle 100, so that the space in the left-right direction Y of the vehicle 100 can be occupied, and the space occupied by the generator controller 190 in the front-to-back direction X of the vehicle 100 can be reduced, so that the vehicle model with a smaller front engine room 260 can use the extended range technology.

[0069] The design of the generator 130 and the generator controller 190 being arranged relative to each other can make the connection between the generator 130 and the generator controller 190 more direct and simple, reduce the length and complexity of wiring, reduce the failure rate caused by wiring problems, and at the same time, make maintenance and repair work more convenient. During the operation of the generator 130, a certain amount of electromagnetic interference will be generated. Since the electromagnetic interference generated by the generator 130 usually diffuses along the radial direction of the rotor 180 of the generator 130, the axial electromagnetic interference of the rotor 180 of the generator 130 is reduced. Therefore, the generator 130 and the generator controller 190 are designed relative to each other in the front-rear direction X of the vehicle 100 (in fact, the axial direction of the generator 130 is parallel to the axial direction of the generator controller 190), which can reduce the electromagnetic interference received by the generator controller 190 to a certain extent, improve the stability and reliability of the operation of the generator controller 190, and thus make the overall operation of the vehicle 100 more stable.

[0070] Please refer to Figures 1 to 6 In this embodiment, the vehicle 100 further includes a charging and distribution device 220 , which is connected to the generator controller 190 and the drive motor controller 210 , respectively. Along the left-right direction Y of the vehicle 100 , the charging and distribution device 220 and the battery pack 140 are arranged opposite to each other.

[0071] The charging and distributing device 220 is connected to the generator controller 190 and the drive motor controller 210 respectively. As an intermediate link, the charging and distributing device 220 realizes the power transmission and information interaction between the generator controller 190 and the drive motor controller 210. It can intelligently distribute power according to the operating status and energy demand of the vehicle 100. The charging and distributing device 220 can monitor and control the flow of power in real time to ensure the efficient use of power. When the power generated by the generator 130 is in excess, it can be stored and supplied in time when the drive motor 150 needs more power.

[0072] Along the left-right direction Y of the vehicle 100, the charging and distribution device 220 and the battery pack 140 are arranged opposite to each other. That is to say, along the left-right direction Y of the vehicle 100, the projection of the charging and distribution device 220 at least partially overlaps with the projection of the battery pack 140. This can effectively improve the space utilization of the vehicle 100 in the front-to-back direction X, reduce the space occupied by the charging and distribution device 220 in the front-to-back direction X of the vehicle 100, and enable models with smaller front engine compartments 260 to be applicable to the extended-range technology, thereby expanding the scope of models to which the extended-range technology is applicable.

[0073] Please refer to Figures 1 to 6 In this embodiment, the vehicle 100 further includes a battery control system 240 , and along the up-down direction Z of the vehicle 100 , the battery control system 240 is arranged opposite to the battery pack 140 .

[0074] The battery pack 140 includes a plurality of cells, which are connected in series or in parallel. The battery pack 140 is used to store electric energy. The battery control system 240 is connected to the battery pack 140 through a data acquisition line, and is used to detect the state of the cells, improve the utilization rate of the battery, prevent the battery from being overcharged and over-discharged, extend the service life of the battery, and monitor the state of the battery. Since the space in the up-down direction Z of the vehicle 100, such as a van or a truck, is relatively large, and the front engine room 260 is relatively small, the battery control system 240 is arranged relative to the battery pack 140 along the up-down direction Z of the vehicle 100, which can fully and effectively utilize the space in the up-down direction Z of the vehicle 100, reduce the space occupied in the up-down direction Z of the vehicle 100, improve the space utilization rate in the front-back direction of the vehicle 100, and enable the vehicle with a smaller front engine room 260 to be applicable to the extended-range technology, thereby expanding the range of vehicle models applicable to the extended-range technology.

[0075] Please refer to Figures 1 to 6 The battery pack 140 includes a first part 290 and a second part 300. Along the front-to-rear direction X of the vehicle 100, the first part 290 is located in front of the second part 300. Along the up-down direction Z of the vehicle 100, the battery control system 240 is arranged on the upper side of the second part 300.

[0076] The first part 290 is located in front of the second part 300, that is, along the front-to-back direction X of the vehicle 100, the first part 290 is arranged in front of the vehicle 100, the second part 300 is arranged at the rear of the vehicle 100, and the battery control system 240 is arranged above the second part 300, that is, the space above the first part 290 of the battery pack 140 can be used to store other components inside the vehicle 100. For some components that need to be arranged under the first seat 160 or under the front cabin 260, the space above the first part 290 of the battery pack 140 can be reasonably utilized, which further reduces the space occupied by the components under the front cabin 260 or the first seat 160, so that there is enough space under the first seat 160 to set components such as the engine 120 or the generator 130.

[0077] For example, a high-strength baffle plate may be provided above the first portion 290 of the battery pack 140. The battery pack 140 has a battery cell inside, and the battery cell has a pressure relief valve. When the battery cell is out of control, the high-temperature and high-pressure substances inside the battery cell will be ejected from the pressure relief valve of the battery cell. If the battery cell is upright, that is, the pressure relief valve of the battery cell is facing upward, when the battery cell is out of control, the high-temperature and high-pressure substances may be ejected upward. At this time, the high-strength baffle plate above the first portion 290 can block the high-temperature and high-pressure substances ejected by the battery cell, greatly improving the safety of passengers in the cockpit.

[0078] Please refer to Figures 1 to 6 In this embodiment, the engine 120 has multiple cylinders, the length direction of the engine 120 is parallel to the front-rear direction X of the vehicle 100, and the axis of the cylinder has an angle with the up-down direction Z of the vehicle 100, and the angle ranges from 45 degrees to 65 degrees.

[0079] Since the vehicle 100, such as a van or a small truck, has a large space under the first seat 160, that is, the space in the up-down direction Z of the vehicle 100 is relatively sufficient, for the extended-range vehicle, the space in the left-right direction Y of the vehicle 100 is relatively cramped, and the length direction of the engine 120 is parallel to the front-rear direction X of the vehicle 100, and the axis of the cylinder has an angle with the up-down direction Z of the vehicle 100, and the angle ranges from 45 degrees to 65 degrees. Exemplarily, the angle can be 50 degrees, which enables the engine 120 to reasonably occupy the space of the vehicle 100 in the up-down direction Z, reduce the space occupied in the left-right direction Y of the vehicle 100, and make the arrangement of internal components of the vehicle 100 more reasonable.

[0080] Please refer to Figures 1 to 6 In this embodiment, the vehicle 100 further includes a second seat 250 , which is disposed on the frame 110 . Along the up-down direction Z of the vehicle 100 , the second seat 250 is disposed opposite to the battery pack 140 .

[0081] The vehicle 100 further includes a second seat 250. The second seat 250 is arranged behind the first seat 160 along the front-rear direction X of the vehicle 100, and the second seat 250 overlaps at least part of the projection of the first seat 160. The second seat 250 is arranged above the vehicle frame 110. The second seat 250 is arranged opposite to the battery pack 140 along the up-down direction Z of the vehicle 100. The battery pack 140 is arranged below the second seat 250. The second seat 250 overlaps at least part of the projection of the battery pack 140 along the up-down direction Z of the vehicle 100. In this way, the space inside the vehicle can be fully utilized, and the battery pack 140 is prevented from occupying other important areas such as the trunk or the front row space, so that the vehicle model with a smaller front cabin 260 can also be applied to the extended-range technology, which expands the scope of application of the vehicle model of the extended-range technology.

[0082] Please refer to Figures 1 to 6 In this embodiment, the vehicle 100 also includes a body-in-white, which has a front engine compartment 260 and a cockpit. The body-in-white has a front panel, which is arranged between the front engine compartment 260 and the cockpit. The engine 120 is located at the rear side of the front panel and at the lower side of the cockpit.

[0083] The body in white refers to the unpainted body structure formed by connecting all metal components (such as steel plates) by welding, bolts, etc. before the assembly of the car. The body in white includes the front engine compartment 260 and the cockpit. The engine 120 is located at the rear side of the front panel and at the lower side of the cockpit. Since the space in the front engine compartment 260 is limited, if the engine 120 is extended into the front engine compartment 260, it may squeeze the space of other key components, such as the cooling system, the electrical system, etc., while not extending the engine 120 into the front engine compartment 260 can ensure that each system has enough space for layout, thereby improving the reliability of the whole vehicle and the convenience of maintenance.

[0084] Since the engine 120 does not extend into the front engine compartment 260, the engine 120 is located at the rear side of the front panel and at the lower side of the cockpit, when the vehicle 100 collides, the crumple space of the front engine compartment 260 is retained. In the event of a frontal collision, this space can absorb part of the impact energy, reduce the impact on the occupants, and improve the safety performance of the user of the vehicle 100. In addition, the engine 120 is arranged at the lower side of the cockpit, which can save space in the front engine compartment 260, so that the vehicle model with a smaller front engine compartment 260 can also be applied to the extended-range technology, thereby expanding the applicable vehicle model range of the extended-range technology.

[0085] In addition, for vehicles with a smaller front engine compartment 260, the maintenance space itself is limited. If the engine 120 extends too far into the front engine compartment 260, it may increase the difficulty of repair and maintenance. On the contrary, keeping the engine 120 in the appropriate position can provide maintenance personnel with a more convenient operating space and reduce maintenance costs and time.

[0086] Please refer to Figures 1 to 6 In this embodiment, along the front-rear direction X of the vehicle 100, the engine 120, the generator 130, the battery pack 140 and the drive motor 150 are relatively arranged.

[0087] Along the front-to-back direction X of the vehicle 100, the engine 120, the generator 130, the battery pack 140 and the drive motor 150 are arranged relatively, that is, at least part of the projections of the engine 120, the generator 130, the battery pack 140 and the drive motor 150 overlap. In this way, on the one hand, the weight distribution of the power system in the vehicle 100 can be more balanced, which helps to reduce the height of the center of gravity of the vehicle 100 and improve the controllability and stability of the vehicle 100. On the other hand, for the integrated cooling system inside the vehicle 100, along the front-to-back direction X of the vehicle 100, the engine 120, the generator 130, the battery pack 140 and the drive motor 150 are arranged relatively, and the heat dissipation demand is more concentrated, which is convenient for designing a unified cooling system and reducing the complexity inside the vehicle 100.

[0088] Furthermore, the engine 120 , the generator 130 , the battery pack 140 , and the drive motor 150 are arranged relatively to each other along the front-rear direction X of the vehicle 100 , which can also reduce the length of the lines between the components and simplify the internal lines of the vehicle 100 .

[0089] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
