[0036] The range issue of new energy vehicles has always been the focus of people's attention. Currently, there are methods to increase the range of new energy vehicles by adding a range extender system in the vehicle. However, there are problems such as low energy conversion efficiency, high fuel consumption during high-speed driving, and long charging time. There is also a method of setting the battery pack in the vehicle to a replaceable structure, that is, the vehicle has a battery swapping mode. The battery swapping mode is to replace the battery in the new energy vehicle to meet the range requirements of the vehicle owner. When the battery pack in the vehicle has insufficient power, the vehicle can be driven into a battery swapping station to replace the fully charged battery, which can greatly save the vehicle owner's energy replenishment time and at the same time make up for the disadvantage of high cost of range extender vehicles during high-speed driving. Integrating range extender and battery swapping technologies in new energy vehicles can greatly solve the range anxiety and vehicle usage cost of users.

[0037] However, currently, in the existing literature, there is no suitable engineering layout scheme for integrating range extender and battery swapping technologies.

[0038] The present utility model proposes a battery swapping range extender vehicle.

[0039] Please refer to Figure 1 and Figure 2 , in an embodiment of the present utility model, the battery swapping range extender vehicle includes a vehicle frame 100, a power module 210, a battery swapping battery pack 220, and a charging power supply module 310. Among them, the power module 210 is installed at the front part of the vehicle frame 100. The power module 210 includes an engine 211 and a range extender power electric drive 212 that are connected. The range extender power electric drive 212 is connected to the rear end of the engine 211.

[0040] Specifically, along the front-rear direction of the vehicle, the vehicle frame 100 is provided with a front part, a middle part, and a rear part. The power module 210 is installed at the front part of the vehicle frame 100, that is, the power module 210 is installed at the front position of the vehicle head. The range-extending power electric drive 212 includes a generator and a drive motor. In one embodiment, the generator and the drive motor are integrated together. The generator is connected to the rear end of the engine 211. There is no clutch structure in the range-extending power electric drive 212, and the engine 211 does not directly participate in driving. The engine 211 is used to drive the generator to generate electricity, and the generated electricity is used to supply the drive motor to drive the vehicle, or the electric energy is stored in the battery swapping battery pack 220. In this way, omitting the clutch structure in the power module 210 is beneficial to the miniaturization and lightweight of the power module 210, which is conducive to the installation of various parts on the vehicle frame 100 and the lightweight of the vehicle. In one embodiment, the engine 211 and the range-extending power electric drive 212 are assembled into an integrated structure and installed at the front cabin position of the vehicle body through a suspension bracket. In this way, it is beneficial to the miniaturization of the power module 210, so that the installation of the power module 210 occupies less space and is conducive to the reasonable arrangement of various components on the vehicle frame 100. Among them, the engine 211 includes but is not limited to gasoline fuel engines, methanol engines, etc. In one embodiment, the engine 211 and the range-extending power electric drive 212 are arranged along the width direction of the vehicle, which is beneficial to the reasonable setting of the installation space under the vehicle floor.

[0041] The battery swapping battery pack 220 is installed in the middle part of the vehicle frame 100. The battery swapping battery pack 220 is used to provide electric energy for the range-extending power electric drive 212, or receive the electric energy generated by the range-extending power electric drive 212.

[0042] Specifically, when the vehicle is driving, the battery swapping battery pack 220 can provide electric energy to the drive motor; when the generator generates electricity and charges the battery swapping battery pack 220, the battery swapping battery pack 220 can receive and store the electric energy. In the present utility model, the battery pack is set as a replaceable structure, that is, the battery swapping battery pack 220 is detachably connected to the vehicle frame 100. In this way, when the power in the battery pack is insufficient and it is difficult to charge or cannot be fully charged, etc., the vehicle can be driven into a battery swapping station to replace the battery pack. In this way, the energy replenishment time can be saved and the range anxiety can be solved. In one embodiment, the size of the battery swapping battery pack 220 is consistent with the standard size and requirements of battery swapping in a vehicle-level battery swapping station, thereby saving the battery swapping time. In one embodiment, the capacity of the battery cores in the battery swapping battery pack 220 can be flexibly developed and designed according to the vehicle configuration and user needs, and the core materials can be flexibly selected and carried. At the same time, the battery swapping battery pack 220 can also be compatible with the upgrade application of new technologies such as semi-solid and solid-state batteries.

[0043] The charging power supply module 310 is installed at the rear part of the vehicle frame 100. The charging power supply module 310 is connected to the battery swapping battery pack 220 and is used to connect an external power supply and the battery swapping battery pack 220.

[0044] Specifically, the charging power module 310 includes an on-board AC / DC power charger, an on-board DC / DC power converter, and a vehicle-used high-voltage connection junction box, which are connected to the battery-swap battery pack 220 through a high-voltage wiring harness, thereby realizing the slow charging and fast charging functions of the vehicle. In one embodiment, the on-board AC / DC power charger, the on-board DC / DC power converter, and the vehicle-used high-voltage connection junction box are integrated into an integrated structure, which is conducive to the miniaturization and compactness of the charging power module 310. In this way, the extended-range power electric drive 212, the battery-swap battery pack 220, and the charging power module 310 are integrated into the vehicle, so that the vehicle can realize a full-range energy replenishment solution with rechargeable, replaceable battery packs, and extended-range drive, which greatly solves the user's range anxiety and vehicle use costs.

[0045] It can be understood that the vehicle frame 100 has a first side 110 facing the ground and a second side 120 facing away from the ground, wherein the power module 210 and the charging power module 310 are respectively mounted on the first side 110 of the vehicle frame 100, and the charging power module 310 is mounted on the second side 120 of the vehicle frame 100. In one embodiment, the charging power module 310 is mounted at a corresponding position of the trunk of the vehicle, and the charging power module 310 can be seen after removing the baffle in the trunk.

[0046] In this way, the power module 210 is arranged at the front of the frame 100, the battery pack 220 is arranged at the middle of the frame 100, and the charging power module 310 is arranged at the rear of the frame 100, so as to make full use of the installation space on the frame 100 and arrange the components reasonably to avoid interference between the components. At the same time, the utility model provides a body layout scheme with production conditions, which meets engineering requirements.

[0047] The technical solution of the present utility model is to provide a power module 210, a battery swapping battery pack 220 and a charging power module 310 in a battery swapping range-extended vehicle, wherein the power module 210 is installed at the front of the frame 100, the battery swapping battery pack 220 is installed at the middle of the frame 100, and the charging power module 310 is installed at the rear of the frame 100. In this way, the present utility model provides an engineered vehicle bottom layout scheme integrating range extension and battery swapping technologies. On the one hand, in the present utility model, the range extension system and the battery swapping module are integrated together, providing the vehicle with a way to extend the range and replace the battery pack, thus solving the range anxiety. On the other hand, by reasonably arranging the installation positions of the power module 210, the battery swapping battery pack 220 and the charging power module 310 on the frame 100, the installation of the various components of the vehicle is more reasonable, avoiding interference between the various components.

[0048] See also Figure 1, in the embodiment of the present utility model, the vehicle frame 100 is further installed with an exhaust system 230. The exhaust system 230 includes an exhaust pipe 231. One end of the exhaust pipe 231 is communicated with the exhaust port of the engine 211, and the other end of the exhaust pipe 231 extends to the rear of the vehicle. An insulating layer 241 is sleeved on the outer side of the part of the exhaust pipe 231 adjacent to the battery swapping battery pack 220; and / or, the exhaust pipe 231 includes a first section 232 located in front of the battery swapping battery pack 220. An insulating cover 242 installed on the vehicle frame 100 is provided at the first section 232, and along the length direction of the vehicle, the projections of the first section 232 and the battery swapping battery pack 220 respectively fall on opposite sides of the insulating cover 242.

[0049] Specifically, the battery swapping range extender vehicle further includes an exhaust system 230, and the exhaust system 230 is installed on the first side 110. The exhaust system 230 includes an exhaust pipe 231, and the exhaust pipe 231 is used for connecting with the exhaust port of the engine 211, so as to process and discharge the combustion exhaust gas of the engine 211. It can be understood that the temperature of the combustion exhaust gas of the engine 211 is generally about 800°-900°. After being cooled by the exhaust pipe 231, the temperature discharged from the exhaust pipe 231 is generally about 120°-150°. Generally, the exhaust pipe 231 needs to extend to the rear of the vehicle for discharge to avoid the influence of hot air on various components of the vehicle when discharging in the middle of the vehicle. In one embodiment, a first lifting lug is provided on the exhaust pipe 231, and a second lifting lug is provided on the vehicle frame 100. The first lifting lug and the second lifting lug are hung to realize the installation of the exhaust pipe 231. In one embodiment, in order to improve the protection of the exhaust pipe 231, a flexible limiting member is provided between the first lifting lug and the second lifting lug. When the exhaust pipe 231 is vibrated, the exhaust pipe 231 abuts against the flexible limiting member, thereby avoiding the hard collision between the exhaust pipe 231 and the vehicle frame 100. In one embodiment, the flexible limiting member is configured as a rubber limiting block.

[0050] It can be understood that the engine 211 is installed at the front of the vehicle frame 100, and the battery swapping battery pack 220 is installed in the middle of the vehicle frame 100. When the exhaust pipe 231 extends from the exhaust port of the engine 211 to the rear of the vehicle, it will necessarily pass through the battery swapping battery pack 220. To avoid the influence of the high temperature of the exhaust pipe 231 on the battery swapping battery pack 220, an insulating layer 241 is sleeved on the part of the exhaust pipe 231 adjacent to the battery swapping battery pack 220. The insulating layer 241 is sleeved outside the exhaust pipe 231 by means of clamping or bonding, etc. In one embodiment, the insulating layer 241 is configured as insulating cotton. In one embodiment, the insulating layer 241 is attached to the outer wall of the exhaust pipe 231, so that the insulating layer 241 and the exhaust pipe 231 occupy as little installation space as possible, thereby facilitating the layout and installation of the exhaust pipe 231. In one embodiment, the thickness of the insulating layer 241 is less than 5 mm.

[0051] The exhaust pipe 231 is connected to the exhaust port of the engine 211 and then extends to the rear of the vehicle. Generally, in the width direction of the vehicle, the exhaust port of the engine 211 is located in the middle of the vehicle. When the exhaust pipe 231 extends to the rear of the vehicle, the exhaust pipe 231 should be arranged as close as possible to the edge of the vehicle frame 100 to avoid the influence of the high temperature of the exhaust pipe 231 on other components. Therefore, the exhaust pipe 231 necessarily includes a first section 232 extending in the width direction of the vehicle. In the front-rear direction of the vehicle, the exhaust pipe 231 is located in front of the battery swapping battery pack 220 and behind the power module 210. To further reduce the influence of the heat of the first section 232 of the exhaust pipe 231 on the battery swapping battery pack 220, a heat shield 242 is installed on the first side 110 of the vehicle frame 100, and the first section 232 is located on the side of the heat shield 242 facing the ground. The heat shield 242 is used to separate the first section 232 and the battery swapping battery pack 220 so that the two cannot face each other. That is, the projections of the first section 232 and the battery swapping battery pack 220 respectively fall on the opposite sides of the heat shield 242, thereby blocking the transfer of the heat of the first section 232 to the battery swapping battery pack 220 and further reducing the thermal damage effect of the exhaust pipe 231 on the battery swapping battery pack 220.

[0052] Please refer to Figure 1 , in the embodiment of the present utility model, the exhaust system 230 further includes an integrated muffler 233 connected to the end of the exhaust pipe 231. The integrated muffler 233 is provided with a front muffler, a rear muffler, and at least one active control valve.

[0053] Specifically, to reduce the exhaust noise of the engine 211, a muffler is installed on the exhaust pipe 231. In one embodiment, the muffler is configured as an integrated muffler 233, which includes a front muffler, a rear muffler, and at least one active control valve. The front muffler is used to eliminate high-frequency noise, the rear muffler is used to eliminate low-frequency noise, and the active control valve can be used to adjust the sound and back pressure of the exhaust system 230 to adapt to different working states of the engine 211 and driving requirements. The integrated muffler 233 is connected to the end of the exhaust pipe 231, that is, the integrated muffler 233 is installed at the rear of the vehicle frame 100. In this way, the front muffler, the rear muffler, and the active control valve are all integrated together, improving the noise processing effect, and at the same time facilitating the miniaturization of the integrated muffler 233 and the installation of the integrated muffler 233.

[0054] Please refer to Figure 1 , in the embodiment of the present utility model, a cooling module 250 is further installed at the front of the vehicle frame 100. The cooling module 250 is located on the side of the power module 210 facing away from the battery swapping battery pack 220, and the cooling module 250 is used for the thermal management of the power module 210 and the battery swapping battery pack 220.

[0055] Specifically, when the engine 211 and the battery swapping battery pack 220 in the power module 210 are working, the engine 211 and the battery swapping battery pack 220 will generate a large amount of heat. To avoid the influence of this heat on the engine 211 and the battery swapping battery pack 220, a cooling module 250 is also installed in the battery swapping range extender vehicle. The cooling module 250 is installed at the front part of the first side 110 of the vehicle frame 100, that is, arranged at the front end of the vehicle body. The cooling module 250 includes a cooling fan, a high-temperature radiator, a low-temperature radiator, a wind guiding and deflecting plate assembly, etc. The cooling module 250 is used for the thermal management control of the engine 211 and the battery swapping battery pack 220, so as to ensure that the engine 211 and the battery swapping battery pack 220 work within the normal temperature range.

[0056] Please refer to Figure 1 and Figure 3 , in the embodiment of the present utility model, a battery swapping beam 260 is further installed in the middle of the vehicle frame 100. The battery swapping beam 260 is used for installing the battery swapping battery pack 220. The inner side of the battery swapping beam 260 is connected to the inner panel 131 of the sill of the vehicle frame 100, the middle part of the battery swapping beam 260 is connected to the inner panel 132 of the A-pillar of the vehicle frame 100, and the outer side of the battery swapping beam 260 is connected to the outer panel 133 of the sill of the vehicle frame 100.

[0057] Specifically, to facilitate the disassembly and assembly of the battery swapping battery pack 220, a battery swapping beam 260 is further installed in the middle of the first side 110 of the vehicle frame 100. For the convenience of description, along the width direction of the vehicle, the direction close to the edge of the vehicle frame 100 is defined as the outer side, and the direction close to the middle of the vehicle frame 100 is defined as the inner side. To ensure the installation stiffness requirement of the battery swapping beam 260, the inner side, the middle part, and the outer side of the battery swapping beam 260 are all connected to the vehicle frame 100. Among them, the inner side of the battery swapping beam 260 is connected to the inner panel 131 of the sill of the vehicle frame 100, the middle part of the battery swapping beam 260 is connected to the inner panel 132 of the A-pillar of the vehicle frame 100, and the outer side of the battery swapping beam 260 is connected to the outer panel 133 of the sill of the vehicle frame 100. In one embodiment, the battery swapping beam 260 is connected to the vehicle frame 100 by welding.

[0058] Please refer to Figure 1 and Figure 3 , in the embodiment of the present utility model, the battery swapping battery pack 220 includes a mounting portion 221, and the mounting portion 221 is connected to the battery swapping beam 260; the projections of the exhaust pipe 231 and the mounting portion 221 are both located on the battery swapping beam 260, and there is a gap between the two projections.

[0059] Specifically, the battery swapping battery pack 220 includes a main body portion 222 and a mounting portion 221. Along the width direction of the vehicle, the two sides of the battery swapping battery pack 220 are the mounting portions 221, and the middle is the main body portion 222. The battery swapping battery pack 220 is connected to the battery swapping beam 260 through the mounting portion 221. It can be understood that the battery swapping beam 260 is installed at the edge of the vehicle frame 100, and part of the exhaust pipe 231 is also installed at the edge of the vehicle frame 100. That is, while the battery swapping beam 260 is for the connection of the mounting portion 221, it also needs to be for the installation of the exhaust pipe 231. In order to reduce the thermal damage effect of the exhaust pipe 231 on the battery swapping battery pack 220, in an embodiment, the battery swapping beam 260 is widened along the width direction of the vehicle, and the projection of the exhaust pipe 231 on the battery swapping beam 260 and the projection of the mounting portion 221 on the battery swapping beam 260 have an interval. In this way, the exhaust pipe 231 and the battery swapping battery pack 220 do not contact, thereby reducing the influence of the thermal damage of the exhaust pipe 231 on the battery swapping battery pack 220.

[0060] Please refer to Figure 1 and Figure 2 , in the embodiment of the present utility model, the vehicle frame 100 has a first side 110 facing the ground and a second side 120 facing away from the ground. The power module 210 and the battery swapping battery pack 220 are respectively installed on the first side 110, and the charging power module 310 is installed on the second side 120; an oxygen generator 320 is also installed at the rear of the second side 120.

[0061] Specifically, an oxygen generator 320 is installed at the rear of the second side 120 of the vehicle frame 100. In an embodiment, the oxygen generator 320 is arranged at the right side position of the rear cabin of the vehicle body, and a power-on interface related to the oxygen generator 320 is reserved here for the vehicle's entire vehicle wiring harness. The oxygen generator 320 can produce an appropriate amount of oxygen when the vehicle occupants need oxygen, meeting the driving needs of the vehicle occupants at high altitudes. In this way, the setting of the oxygen generator 320 improves the applicable range of the vehicle.
