Description

[0002] With the continuous development of the new energy vehicle industry, pure electric vehicles are increasingly favored by individual consumers. However, pure electric vehicles themselves have problems such as long charging time and short driving range on a single full charge. Extended-range electric vehicles are gradually becoming the development trend of electric vehicles by virtue of their advantages such as increased driving range and continuous charging.

[0003] Compared with the basic models of traditional fuel vehicles, extended-range vehicles have an additional electric system, which is generally added to the front cabin of the car. The increase in system components will inevitably take up more space. Therefore, compared with the basic models of ordinary fuel vehicles, the front cabin of extended-range vehicles requires more space for layout, and the number of single components increases, resulting in increased costs and more complex assembly. Most of the existing extended-range front cabin layout structures are front-range extended and rear-drive, with the battery placed on the rear side, resulting in some high-voltage wires being connected from the front to the rear of the vehicle, sacrificing some layout space for the battery compartment; at the same time, the increase in the layout of components in the trunk will lead to a reduction in the storage space of the trunk; compared with electric vehicles, the temperature of the front cabin of extended-range vehicles is higher, and the cooling rate requirements are higher.

[0025] like Figure 1 to Figure 2 As shown, an embodiment of the present invention provides a front cabin layout structure of an extended-range vehicle, wherein a front end frame 1, a tower package cross beam 2, a right suspension 3 and a left suspension 4 are respectively arranged around the front cabin, the front end frame 1 and the tower package cross beam 2 are respectively located at the front end and the rear end of the front cabin, and the left suspension 4 and the right suspension 3 are respectively located on both sides of the front cabin.

[0026] The front cabin layout structure includes a super composite power module 5, a thermal management integrated module 6, a battery module 7, an engine kettle 8, a two-in-one kettle 9, an air filter 100 and an electronic control module 110 (ECU); the super composite power module 5 is arranged at the center of the front cabin, the two-in-one kettle 9 and the electronic control module 110 are located below the tower package cross beam 2, and the thermal management integrated module 6 is located below the two-in-one kettle 9 and the electronic control module 110; the battery module 7 is located above the left suspension 4, the engine kettle 8 is arranged on the front end frame 1, and the air filter 100 is located above the right suspension 3.

[0027] Specifically, based on the thermal management principle of the whole vehicle, the engine kettle 8 and the two-in-one kettle 9 are arranged on the front frame 1 and the right suspension 3 respectively, which effectively shortens the water pipe connection and avoids the crossing of the pipe bundles.

[0028] The ECU is arranged below the tower package cross beam 2, close to the rear of the super composite power module 5, which not only meets the collision safety requirements, but also effectively avoids the engine 501 wiring harness from excessively occupying the front cabin layout space, while reducing the wiring harness cost.

[0029] The present invention arranges the front frame 1 and the tower cross beam 2 at the front and rear ends of the front cabin respectively, and the left suspension 4 and the right suspension 3 are arranged on both sides of the front cabin respectively; and the super compound power module 5 is arranged at the center of the front cabin, the two-in-one kettle 9 and the electronic control module 110 are arranged below the tower cross beam 2, and the thermal management integrated module 6 is arranged below the two-in-one kettle 9 and the electronic control module 110; the battery module 7 is arranged above the left suspension 4, the engine kettle 8 is arranged on the front frame 1, and the air filter 100 is arranged above the right suspension 3. The layout structure of the extended-range front cabin vehicle of the present invention can make the extended-range vehicle effectively utilize the front cabin space and realize the reasonable layout of the front cabin when the number of front cabin components of the extended-range vehicle is more than that of the traditional fuel vehicle, so that the extended-range vehicle can reduce the development cost and cycle of the whole vehicle under the premise of realizing the functions of each component and meeting the safety requirements of regulations, and simultaneously improve the thermal management performance and efficiency.

[0030] In one embodiment of the front cabin arrangement structure of the range-extended vehicle of the present invention, Figure 1 to Figure 2 As shown, the super hybrid power module 5 includes an engine 501, a three-way catalytic converter 502, a transmission 503, a motor 504, a reducer 505, a motor controller 506 (PCU), an engine controller 507, a high-voltage power distribution unit 508 (PDU), a charger 509 (OBC), a DC-DC converter 510 (DC-DC), a super fast charger 511 and a water heater 512 (WPTC), which are arranged in four groups in sequence.

[0031] Specifically, the sizes of the above-mentioned engine 501, three-way catalytic converter 502, transmission 503, motor 504, reducer 505, motor controller 506, engine controller 507, high-voltage distribution unit 508, charger 509, DC-DC converter 510, super fast charging 511 and water heater 512 are comparable to those of traditional extended-range power systems. The highly integrated components can effectively improve production and assembly efficiency, reduce some connecting wiring harnesses and mounting brackets, and effectively reduce development costs.

[0032] In one embodiment of the front cabin arrangement structure of the range-extended vehicle of the present invention, Figure 1 to Figure 2 As shown, the motor 504, the motor controller 506, the high-voltage distribution unit 508 and the super fast charger 511 are arranged in sequence from the front end frame 1 toward the tower package beam 2 as the first group, the reducer 505, the engine controller 507, the charger 509, the DC-DC converter 510 and the water heater 512 are arranged in sequence from the front end frame 1 toward the tower package beam 2 as the second group, the transmission 503 is the third group, the three-way catalytic converter 502 and the engine 501 are arranged in sequence from the front end frame 1 toward the tower package beam 2 as the fourth group, and the first group, the second group, the third group and the fourth group are arranged in sequence from the left suspension 4 to the right suspension 3.

[0033] Specifically, the three-way catalytic converter 502 is disposed close to the front end frame 1 , which reduces the impact of heat damage on the passenger compartment, while avoiding the impact of heat damage to the water circulation in the thermal management integrated module 6 caused by the rear placement of the three-way catalytic converter 502 .

[0034] The battery is arranged above the left suspension 4, which shortens the length of the low-voltage wire harness and reduces the cost of the wire harness while meeting the collision safety requirement.

[0035] And specifically, the air filter 100 is staggered with the engine 501 and arranged above the right suspension 3, which reduces the Z-direction height of the front cabin components, reserves redundant space for the car shape while meeting pedestrian protection regulations, and shortens the car development cycle and cost.

[0037] Furthermore, the thermal management integrated module 6 includes a motor 504 water pump, a battery water pump, a heater water pump, a ten-way valve, a battery cooler (Chiller), a water-to-water heat exchanger, a water-cooled condenser (WCC) and a flow channel plate, a total of 8 components. Compared with a heat pump extended-range vehicle with a non-integrated thermal management system, the number of pipeline harnesses is reduced by 20% and the length of the pipeline is shortened by 21%, which can effectively improve the thermal management performance and efficiency while reducing costs.

[0038] The super hybrid power system of the present invention integrates 12 components, and the thermal management integrated module 6 integrates 8 components, which effectively reduces the weight of the vehicle and the assembly steps, reduces the development of brackets, shortens the connecting harnesses, reduces costs, and improves assembly processability.

[0039] In one embodiment of the front cabin arrangement structure of the range-extended vehicle of the present invention, Figure 1 to Figure 2 As shown, the front cabin arrangement structure further includes a relay box 120 , which is disposed on the outer side of the left suspension 4 , and the battery module 7 is located between the relay box 120 and the super hybrid power module 5 .

[0040] The present invention arranges the relay box 120 on the outer side of the left suspension 4 , and the battery module 7 is located between the relay box 120 and the super hybrid power module 5 , thereby further shortening the length of the low-voltage wire harness and reducing the cost of the wire harness.

[0041] In one embodiment of the front cabin arrangement structure of the range-extended vehicle of the present invention, Figure 1 to Figure 2 As shown, the front cabin arrangement structure also includes a washing pot 130 , which is arranged at the front end of the left suspension 4 and located at the first end of the front frame 1 .

[0042] The present invention arranges the washing pot 130 at the front end of the left suspension 4 and at the first end of the front end frame 1, so as to contain washing liquid, transmit the washing liquid to the nozzle through the washing pipe, and spray the washing liquid onto the front windshield of the car by the nozzle, so as to facilitate the wiper to clean the glass.

[0043] In one embodiment of the front cabin arrangement structure of the range-extended vehicle of the present invention, Figure 1 to Figure 2 As shown, the front cabin arrangement structure further includes a gas-liquid separator 140 , which is disposed at the front end of the right suspension 3 and located at the second end of the front end frame 1 .

[0044] The present invention arranges the gas-liquid separator 140 at the front end of the right suspension 3 and at the second end of the front end frame 1, thereby separating the liquid and gas entering the gas-liquid separator 140, preventing the liquid refrigerant from directly entering the compressor, thereby avoiding damage to the compressor due to liquid hammer.

[0045] In one embodiment of the front cabin arrangement structure of the extended-range vehicle of the present invention, in order to further improve the driving safety of the extended-range vehicle, the front cabin arrangement structure further includes a pedestrian reminding device 150 , and the pedestrian reminding device 150 is disposed on the front end frame 1 .
