[0036] The endurance of new energy vehicles has always been the focus of attention. At present, there are ways to increase the range of new energy vehicles by adding a range-extending system to the vehicle, but it has problems such as low energy conversion efficiency, high fuel consumption at high speeds, and long charging time. There is also a way to set the battery pack in the vehicle to a replaceable structure, that is, the vehicle has a battery swap mode. The battery swap mode is to replace the battery in the new energy vehicle to meet the owner's endurance needs. When the battery pack in the vehicle is low on power, the vehicle can be driven into a battery swap station to replace the battery with a full charge, which can greatly save the owner's recharging time and make up for the disadvantage of the high cost of high-speed driving of the range-extending vehicle. Integrating range-extending and battery swapping technologies in new energy vehicles can greatly solve users' range anxiety and vehicle use costs.

[0037] However, currently in the existing literature, there is no suitable engineering layout solution for integrating range extension and battery replacement technologies.

[0038] The present invention provides a battery-swap range-extended vehicle.

[0039] See also Figure 1 and Figure 2 In one embodiment of the present invention, the battery-swap extended-range vehicle includes a frame 100, a power module 210, a battery-swap battery pack 220 and a charging power module 310, wherein the power module 210 is installed at the front of the frame 100, and the power module 210 includes a connected engine 211 and an extended-range power electric drive 212, and the extended-range power electric drive 212 is connected to the rear end of the engine 211.

[0040] Specifically, along the front and rear direction of the vehicle, the 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 frame 100, that is, the power module 210 is installed at the front position of the vehicle. The extended-range power electric drive 212 includes a generator and a drive motor. In one embodiment, the generator and the drive motor are integrated together, and the generator is connected to the rear end of the engine 211. There is no clutch structure in the extended-range power electric drive 212, and the engine 211 does not directly participate in the drive. The engine 211 is used to drive the generator to generate electricity, and the generated electricity is used to provide the drive motor to drive the vehicle, or the electric energy is stored in the battery replacement battery pack 220. In this way, the clutch structure is omitted in the power module 210, which is conducive to the miniaturization and lightweight of the power module 210, thereby facilitating the installation of various parts on the frame 100 and facilitating the lightweight of the vehicle. In one embodiment, the engine 211 and the extended-range 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. This is conducive to the miniaturization of the power module 210, so that the installation space of the power module 210 is small, which is conducive to the reasonable arrangement of various components on the frame 100. Among them, the engine 211 includes but is not limited to a gasoline fuel engine, a methanol engine, etc. In one embodiment, the engine 211 and the extended-range power electric drive 212 are arranged along the width direction of the vehicle, which is conducive to the reasonable arrangement of the installation space under the vehicle.

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

[0042] Specifically, when the vehicle is driven, the battery-swap battery pack 220 can provide electrical energy to the drive motor; when the generator generates electricity and charges the battery-swap battery pack 220, the battery-swap battery pack 220 can receive and store electrical energy. In the present invention, the battery pack is set to a replaceable structure, that is, the battery-swap battery pack 220 is detachably connected to the frame 100. In this way, when the battery pack is low on power and it is difficult to charge or cannot be fully charged, the vehicle can be driven into the battery-swap station to replace the battery pack. In this way, it is possible to save energy replenishment time and solve range anxiety. In one embodiment, the size of the battery-swap battery pack 220 is consistent with the standard size and requirements for battery swapping at a vehicle-level battery-swap station, thereby saving battery swap time. In one embodiment, the battery cell capacity in the battery-swap battery pack 220 can be flexibly developed and designed according to the configuration of the entire vehicle and user needs, and the core material can be flexibly selected and carried. At the same time, the battery-swap battery pack 220 can also be compatible with the upgrade and application of new technology batteries such as semi-solid and solid-state.

[0043] The charging power module 310 is installed at the rear of the frame 100 . The charging power module 310 is connected to the battery replacement pack 220 and is used to connect an external power source and the battery replacement 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 present invention provides a body layout scheme with production conditions, which meets engineering requirements.

[0047] The technical solution of the present invention is to provide a power module 210, a battery swapping battery pack 220 and a charging power module 310 in a battery swapping extended-range 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 invention provides an engineered vehicle bottom layout scheme integrating range extension and battery swapping technologies. On the one hand, in the present invention, 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 for battery life, thereby 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, and interference between the components is avoided.

[0048] See also Figure 1In an embodiment of the present invention, the vehicle frame 100 is further equipped with an exhaust system 230, and the exhaust system 230 includes an exhaust pipe 231, one end of which is connected to the exhaust port of the engine 211, and the other end of the exhaust pipe 231 extends to the rear of the vehicle. The outer side of the portion of the exhaust pipe 231 adjacent to the battery swapping pack 220 is sheathed with a heat insulating layer 241; and / or, the exhaust pipe 231 includes a first section 232 located in front of the battery swapping pack 220, and a heat 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 pack 220 fall on opposite sides of the heat insulating cover 242 respectively.

[0049] Specifically, the battery-swap extended-range vehicle also includes an exhaust system 230, which is installed on the first side 110. The exhaust system 230 includes an exhaust pipe 231, which is used to connect to the exhaust port of the engine 211, so as to process and lead out 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 around 800°-900°. After the exhaust pipe 231 cools down, the temperature of the exhaust gas discharged from the exhaust pipe 231 is generally around 120°-150°. Generally, the exhaust pipe 231 needs to extend to the rear of the vehicle for discharge to avoid the impact of hot air on various components of the vehicle when it is discharged 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 frame 100. The first lifting lug and the second lifting lug are hooked to achieve the installation of the exhaust pipe 231. In one embodiment, in order to improve the protection of the exhaust pipe 231, a flexible stopper is provided between the first hanging ear and the second hanging ear, and when the exhaust pipe 231 is vibrated, the exhaust pipe 231 abuts against the flexible stopper, thereby avoiding a hard collision between the exhaust pipe 231 and the frame 100. In one embodiment, the flexible stopper is configured as a rubber stopper.

[0050] It can be understood that the engine 211 is installed at the front of the frame 100, the battery-swap pack 220 is installed in the middle of the frame 100, and the exhaust pipe 231 must pass through the battery-swap pack 220 when extending from the exhaust port of the engine 211 to the rear of the vehicle. In order to avoid the influence of the high temperature of the exhaust pipe 231 on the battery-swap pack 220, a heat-insulating layer 241 is sleeved on the part of the exhaust pipe 231 adjacent to the battery-swap pack 220. The heat-insulating layer 241 is sleeved on the outside of the exhaust pipe 231 by means of clipping or bonding. In one embodiment, the heat-insulating layer 241 is configured as heat-insulating cotton. In one embodiment, the heat-insulating layer 241 is attached to the outer wall of the exhaust pipe 231, so that the heat-insulating layer 241 and the exhaust pipe 231 occupy as little installation space as possible, thereby facilitating the arrangement and installation of the exhaust pipe 231. In one embodiment, the thickness of the heat-insulating layer 241 is less than 5 mm.

[0051] The exhaust pipe 231 is connected to the exhaust port of the engine 211 and extends to the rear of the vehicle. Generally, along 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 set as close to the edge of the frame 100 as possible to avoid the influence of the high temperature of the exhaust pipe 231 on other components. Therefore, the exhaust pipe 231 must include a first section 232 extending along the width direction of the vehicle. Along the front and rear direction of the vehicle, the exhaust pipe 231 is located in front of the battery-swap battery pack 220 and in the rear of the power module 210. In order to further reduce the influence of the heat of the first section 232 of the exhaust pipe 231 on the battery-swap battery pack 220, a heat shield 242 is installed on the first side 110 of the 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-swap battery pack 220 so that the two cannot face each other. That is, the projections of the first section 232 and the battery exchange battery pack 220 fall on opposite sides of the heat insulation cover 242, respectively, thereby blocking the heat of the first section 232 from being transferred to the battery exchange battery pack 220, further reducing the heat damage of the exhaust pipe 231 to the battery exchange battery pack 220.

[0052] See also Figure 1 In an embodiment of the present invention, the exhaust system 230 further includes an integrated muffler 233 connected to the end of the exhaust pipe 231, and the integrated muffler 233 is provided with a front muffler, a rear muffler and at least one active control valve.

[0053] Specifically, in order 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 conditions and driving requirements of the engine 211. 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 frame 100. In this way, the front muffler, the rear muffler and the active control valve are integrated together, which improves the noise processing effect, and is also conducive to the miniaturization of the integrated muffler 233 and the installation of the integrated muffler 233.

[0054] See also Figure 1 In an embodiment of the present invention, a cooling module 250 is also installed at the front of the frame 100. The cooling module 250 is located on the side of the power module 210 away from the battery replacement battery pack 220. The cooling module 250 is used for thermal management of the power module 210 and the battery replacement battery pack 220.

[0055] Specifically, when the engine 211 and the battery-swap battery pack 220 in the power module 210 are working, the engine 211 and the battery-swap battery pack 220 will generate a lot of heat. In order to avoid the influence of this heat on the engine 211 and the battery-swap battery pack 220, a cooling module 250 is also installed in the battery-swap extended-range vehicle. The cooling module 250 is installed at the front of the first side 110 of the frame 100, that is, it 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, and an air guide plate assembly. The cooling module 250 is used for thermal management control of the engine 211 and the battery-swap battery pack 220, so as to ensure that the engine 211 and the battery-swap battery pack 220 operate within a normal temperature range.

[0056] See also Figure 1 and Figure 3 In an embodiment of the present invention, a battery swap beam 260 is also installed in the middle of the frame 100. The battery swap beam 260 is used for installing the battery swap battery pack 220. The inner side of the battery swap beam 260 is connected to the door sill inner plate 131 of the frame 100, the middle part of the battery swap beam 260 is connected to the A-pillar inner plate 132 of the frame 100, and the outer side of the battery swap beam 260 is connected to the door sill outer plate 133 of the frame 100.

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

[0058] See also Figure 1 and Figure 3 In an embodiment of the present invention, the battery-exchange battery pack 220 includes a mounting portion 221, which is connected to the battery-exchange beam 260; the projections of the exhaust pipe 231 and the mounting portion 221 are both located on the battery-exchange beam 260, and there is a gap between the two projections.

[0059] Specifically, the battery-swap battery pack 220 includes a main body 222 and a mounting portion 221. Along the width direction of the vehicle, the two sides of the battery-swap battery pack 220 are mounting portions 221, and the middle is the main body 222. The battery-swap battery pack 220 is connected to the battery-swap beam 260 through the mounting portion 221. It can be understood that the battery-swap beam 260 is installed at the edge of the frame 100, and part of the exhaust pipe 231 is also installed at the edge of the frame 100. That is, the battery-swap beam 260 needs to be installed for the exhaust pipe 231 while the mounting portion 221 is connected. In order to reduce the heat damage of the exhaust pipe 231 to the battery-swap battery pack 220, in one embodiment, the battery-swap beam 260 is widened along the width direction of the vehicle, and the projection of the exhaust pipe 231 on the battery-swap beam 260 and the projection of the mounting portion 221 on the battery-swap beam 260 are spaced apart. In this way, there is no contact between the exhaust pipe 231 and the battery-exchange battery pack 220 , thereby reducing the impact of heat damage from the exhaust pipe 231 on the battery-exchange battery pack 220 .

[0060] See also Figure 1 and Figure 2 In an embodiment of the present invention, the 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 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 concentrator 320 is installed at the rear of the second side 120 of the vehicle frame 100. In one embodiment, the oxygen concentrator 320 is arranged at the right side of the rear compartment of the vehicle body, and the vehicle wiring harness reserves a power-on interface related to the oxygen concentrator 320. The oxygen concentrator 320 can produce an appropriate amount of oxygen when the driver and passengers in the vehicle need oxygen, so as to meet the driving needs of the driver and passengers at plateaus and high altitudes. In this way, the setting of the oxygen concentrator 320 increases the scope of application of the vehicle.

[0062] See also Figure 2 In an embodiment of the present invention, a battery 330 is further installed at the rear of the second side 120 , and the charging power module 310 is located between the battery 330 and the oxygen generator 320 .

[0063] Specifically, the battery 330 is used to supply power to the low-voltage electrical system of the vehicle, as well as to start and stabilize the high-voltage system. In one embodiment, the battery 330 is installed on the left side of the rear compartment of the vehicle body, which solves the problem that there is no installation space for the battery 330 after the power module 210 is arranged in the front compartment of the vehicle body.

It is worth noting that the front end and the rear end refer to the front and rear of the vehicle. According to the layout design of the vehicle body, the layout position and form of the rear suspension 280 and the fuel tank 270 can be flexibly matched according to the vehicle model requirements. In this way, the oil tank 270 is disposed close to the rear suspension 280, so that the space at the rear of the first side 110 of the frame 100 is reasonably utilized, and the arrangement of the components on the frame 100 is more reasonable.

[0066] In an embodiment of the present invention, an anti-fall monitoring module is provided between the battery replacement battery pack 220 and the vehicle frame 100 .

[0067] Specifically, in order to ensure that the battery-swap battery pack 220 is installed in place, an anti-drop monitoring module is provided between the battery-swap battery pack 220 and the vehicle frame 100. In one embodiment, the anti-drop monitoring module includes an in-place sensor provided on the battery-swap battery pack 220. When the battery-swap battery pack 220 is installed in place, the in-place sensor contacts the vehicle frame 100 and transmits the in-place signal to the controller. After the controller receives and processes the signal, the in-place information can be displayed on the display instrument of the vehicle, thereby knowing that the battery-swap battery pack 220 has been installed in place. It is worth noting that the control logic between the in-place sensor and the controller belongs to the prior art and will not be repeated here. The provision of the anti-drop monitoring module is conducive to ensuring that the battery pack is firmly installed and does not fall during the battery-swap process.

[0068] See also Figure 1 In an embodiment of the present invention, the frame 100 is also equipped with a sub-frame 290 for installing the power module 210. The sub-frame 290 is located between the power module 210 and the battery pack 220, and the sub-frame 290 is configured in a butterfly shape.

[0069] Specifically, the subframe 290 is installed on the first side 110 of the frame 100 and is located between the power module 210 and the battery replacement battery pack 220. The power module 210 is mounted on the frame 100 through a suspension bracket, wherein the suspension bracket includes a rear suspension bracket, and the rear side of the power module 210 is mounted on the subframe 290 through the rear suspension bracket. The subframe 290 provides a support and fixing point for the power module 210, and can also reduce the vibration transmitted to the vehicle body. In one embodiment, the subframe 290 is configured as a butterfly structure, so that while satisfying the stiffness mode, it is also conducive to the lightweight of the subframe 290.

[0070] Thus, in the present application, on the side of the frame 100 facing the ground, from the front to the rear of the vehicle, a cooling module 250, a power module 210, a battery pack 220 and a rear suspension 280 are arranged in sequence, and an exhaust pipe 231 is also connected to the exhaust port of the engine 211 in the power module 210. The exhaust pipe 231 is provided with a heat insulation layer 241 and / or a heat insulation cover 242 at a position adjacent to the battery pack 220. A battery beam 260 is provided on both sides of the battery pack 220, and a fuel tank 270 is provided near the rear suspension 280. At the rear of the vehicle on the side of the frame 100 facing away from the ground, a battery 330, a charging power module 310 and an oxygen generator 320 are provided. In this way, the space on the frame 100 is used to reasonably arrange the various components, breaking through the physical layout space limitations of the entire vehicle and avoiding interference between the various components.
