DETAILED DESCRIPTION
[0026] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0027] In the description of this application, unless otherwise specified or limited, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.
[0028] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described from the perspectives shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also indirectly connected to the other element "on" or "under" through an intermediate element.
[0029] As the domestic new energy vehicle market continues to expand, demand for pure electric and plug-in hybrid vehicles is also increasing. However, due to limitations in battery technology, pure electric vehicles generally have limited range in cold weather, leading to range anxiety for long-distance drivers. Therefore, plug-in hybrid vehicles, which fall between fuel vehicles and pure electric vehicles, have become the preferred choice for users concerned about range.
[0030] A plug-in hybrid electric vehicle (PHEV) is a type of plug-in hybrid vehicle. Its technical characteristics are that it adds a battery and motor system to the original gasoline-powered vehicle. The engine does not directly drive the vehicle, but is used only for power generation. This allows the engine to operate at an economical speed range, effectively reducing fuel consumption. Compared with gasoline-powered and pure electric vehicles, hybrid vehicles are more complex in structure, resulting in more limited space for layout within the same vehicle size. Due to the limited space in the front cabin (engine compartment) of a plug-in hybrid vehicle, the placement of the range extender will occupy most of the front cabin, making the front cabin layout of a hybrid vehicle more difficult than that of a traditional gasoline-powered vehicle.
[0031] At present, plug-in hybrid vehicles mostly adopt front-mounted front-drive engine transverse arrangement form, which cannot be compatible with front-mounted rear-drive fuel vehicles and pure electric vehicles at the same time, because most plug-in hybrid vehicles are front-drive or four-wheel drive vehicles, the engine power directly participates in driving the vehicle, and the front-mounted front-drive engine transverse arrangement is more conducive to the arrangement of the front-wheel drive shaft. The front-mounted front-drive transverse power engine and the front-mounted rear-drive longitudinal power engine have different arrangements and different chassis hard points, and the same vehicle cannot be compatible with the transverse and longitudinal power engine arrangements at the same time, so the chassis with the front-mounted front-drive transverse arrangement cannot be compatible with the front-mounted rear-drive longitudinal fuel vehicle at the same time. At the same time, the charging and power supply module of the current plug-in hybrid vehicle is usually arranged under the trunk, which may cause the problem of smaller or poorer flatness of the trunk space, or the charging and power supply module is arranged under the driver's seat, which may have NVH (noise, vibration and harshness) problem. Because the charging and power supply module is arranged under the driver's seat, it is close to the passenger, and when the charging and power supply module works, the cooling system works and makes a sound, which can be felt by the passenger. In addition, through collision analysis, the low-voltage storage battery is arranged on the left side, and when the offset collision occurs, it is more likely to be squeezed and hit the brake master cylinder (the brake master cylinder is arranged on the left side of the front compartment), causing the positive electrode wire harness of the storage battery to be pressed off.
[0032] However, the inventors have found through practice and analysis that the problems of safety collision, electromagnetic interference, after-sales maintenance convenience and NVH can be solved by optimizing the arrangement method, so that the newly developed front-mounted rear-drive plug-in range-extending hybrid commercial vehicle can meet the market demand. Based on this, the inventors of the present application provide a front compartment arrangement method of a front-mounted rear-drive plug-in range-extending hybrid vehicle, which can solve the problems of safety collision, electromagnetic interference, after-sales maintenance convenience and NVH faced by the traditional vehicle front compartment arrangement, and effectively reduce the pipeline cost.
[0033] Referring to Figure 1 The embodiment of the present application discloses a vehicle 100, which comprises a vehicle body 101 and a plurality of vehicle wheels 102, wherein the plurality of vehicle wheels 102 are respectively connected to the bottom of the vehicle body 101, so that the vehicle can run through the vehicle wheels 102. The vehicle body 101 has a driver's cabin 2 and a front compartment 1, wherein the front compartment 1 is located in front of the driver's cabin 2 along the arrow direction in the drawing (i.e. the direction of travel of the vehicle 100), and the front compartment 1 is usually used for mounting a driving system, and the driver's cabin 2 is usually used for the driver to perform driving operation. Figure 1
[0034] It should be noted that, from the position of the driver, the front of the driver is defined as the front end of the vehicle, the rear of the driver is defined as the rear end of the vehicle, the left of the driver is defined as the left side of the vehicle, and the right of the driver is defined as the right side of the vehicle, so in the following description, the left, right, front and rear of the front compartment are defined as the left, right, front and rear indicated in the drawing. Figure 2 .
[0035] Referring to Figure 2 and Figure 3 As shown in FIG. 1, the vehicle body 101 includes an upper bending beam 101a, a left front beam 101b, a left bending beam 101c, a left side plate 101d, a left front wheel cover 101e, a left front headlamp 101f, a front windshield 101g, a right front wheel cover 101h, a right front beam 101i, a front axle welding piece, a front floor tunnel, a steering engine, a water channel, a swing arm welding piece, and a brake master cylinder. The left front beam 101b is located at the left side of the front compartment 1, the upper bending beam 101a is connected with the left front beam 101b and located at the front end of the front compartment 1, and the front windshield 101g is connected with the upper bending beam 101a and located at the front end of the front compartment 1. The left front wheel cover 101e is connected with the left front beam 101b and located at the left side of the front compartment 1, the left side plate 101d is connected with the left front beam 101b and the left front wheel cover 101e, and the left bending beam 101c is connected with the left front beam 101b and the left side plate 101d. The left front headlamp 101f is installed on the left bending beam 101c. The right front beam 101i is located at the right side of the front compartment 1, and the right front wheel cover 101h is connected with the right front beam 101i. The front axle welding piece is connected with the left front beam 101b and the right front beam 101i.
[0036] Referring to Figure 4 As shown in FIG. 1, the front compartment 1 is provided with a first mounting area 10a, a second mounting area 10b, a third mounting area 10c, and a fourth mounting area 10d. The first mounting area 10a, the second mounting area 10b, and the third mounting area 10c are distributed along the width direction (the left-right direction in the figure) of the vehicle body, and the first mounting area 10a and the third mounting area 10c are respectively located at the two sides of the second mounting area 10b. The fourth mounting area 10d is located at the end of the second mounting area 10b away from the driver's cabin 2, i.e., the fourth mounting area 10d is located at the front end of the second mounting area 10b. The vehicle 100 further includes a range extender assembly 3, a charging and power distribution assembly 4, a low-voltage storage battery assembly 5, and a high-voltage power battery. The range extender assembly 3 is arranged in the second mounting area 10b, and the length of the range extender assembly 3 extends along the length direction of the vehicle 100, i.e., the range extender assembly 3 is installed in the second mounting area 10b of the front compartment 1 in a longitudinal manner. The range extender assembly 3 can be used for power generation to provide electric energy for the vehicle. The charging and power distribution assembly 4 is arranged in the third mounting area 10c, and the distance between the charging and power distribution assembly 4 and the driver's cabin 2 is greater than the distance between the range extender assembly 3 and the driver's cabin 2. The charging and power distribution assembly 4 can be used for charging and discharging and voltage conversion. The low-voltage storage battery assembly 5 is arranged in the first mounting area 10a, and the distance between the low-voltage storage battery assembly 5 and the driver's cabin 2 is greater than the distance between the range extender assembly 3 and the driver's cabin 2. The low-voltage storage battery assembly 5 can be used to provide electric energy for the low-voltage electrical appliances of the whole vehicle. The high-voltage power battery is used to provide electric energy for the high-voltage equipment of the vehicle.
[0037] The distance between the charging and power distribution assembly 4 and the cockpit 2 is defined as the distance between the front end of the charging and power distribution assembly 4 and the front end of the cockpit 2; the distance between the range extender assembly 3 and the cockpit 2 is defined as the distance between the front end of the range extender assembly 3 and the front end of the cockpit 2; and the distance between the low-voltage battery assembly 5 and the cockpit 2 is defined as the distance between the front end of the low-voltage battery assembly 5 and the front end of the cockpit 2.
[0038] The range extender assembly 3 is longitudinally arranged, which is compatible with front-engine rear-drive fuel vehicles and pure electric vehicles. The charging and power distribution assembly 4 is arranged on the left side of the range extender assembly 3, which avoids the problem of small or poor flatness of the trunk space caused by arranging the charging and power distribution assembly in the trunk, and avoids the NVH problem caused by arranging the charging and power distribution assembly under the co-pilot seat. In addition, the exhaust side of the range extender assembly 3 is on the left side of the front compartment, and the charging and power distribution assembly is arranged as far as possible from the heat hazard risk, while meeting the vehicle collision requirements and electromagnetic compatibility requirements and the limited arrangement space of the front compartment 1. Therefore, the charging and power distribution assembly is arranged in front of the left front wheel cover on the left side of the front compartment, which makes the distance between the charging and power distribution assembly and the exhaust side of the range extender assembly larger. In addition, the low-voltage battery assembly 5 is arranged on the right side of the front compartment, which can avoid the situation that the positive lead bundle of the low-voltage battery is broken during the front compartment collision or offset collision, resulting in power failure and the door cannot be opened. Because, through collision analysis, the low-voltage battery arranged on the left side is more likely to be squeezed and hit the brake master cylinder (arranged on the left side of the front compartment) during offset collision, causing the positive lead bundle of the battery to be broken.
[0039] With reference to the foregoing Figure 4As shown, the vehicle 100 further comprises a charging socket 6, an air intake system 7, a heat dissipation assembly 8, a three-way catalyst 9, a low-temperature expansion pot 10, a high-temperature expansion pot 11, an insurance box 12, a brake master cylinder booster 13, and a drive motor (not shown in the figure). The charging socket 6 is arranged in the third mounting area 10c, and the distance between the charging socket 6 and the cockpit 2 is less than the distance between the charging and power distribution assembly 4 and the cockpit 2. The charging socket 6 is used to connect the charging gun. The heat dissipation assembly 8 is arranged in the fourth mounting area 10d and is used to dissipate heat for the range extender assembly and the drive motor. The heat dissipation assembly 8 can include a radiator, an electronic fan, etc. The air intake system 7 is arranged in the second mounting area 10b and extends to the third mounting area 10c, and at least part of the air intake system 7 is located between the heat dissipation assembly 8 and the range extender assembly 3. The air inlet of the air intake system 7 extends towards the direction of the heat dissipation assembly 8. Specifically, the air intake system 7 can be fixed on the upper bent beam 101a. The air intake system 7 is used to provide gas for internal combustion of the range extender assembly 3. The three-way catalyst 9 is arranged in the second mounting area 10b and is located on the left side of the range extender assembly 3 and is used to purify vehicle exhaust. The low-temperature expansion pot 10 is arranged in the second mounting area 10b and extends to the first mounting area 10a. The low-temperature expansion pot 10 is closer to the heat dissipation assembly 8 than the low-voltage battery assembly 5. The low-temperature expansion pot 10 is used to adjust the volume change of the cooling liquid of the drive motor and the battery cooling circuit, maintain the stability of the system pressure, and ensure efficient heat dissipation. The high-temperature expansion pot 11 is arranged in the third mounting area 10c and is closer to the cockpit 2 than the charging and power distribution assembly 4. The high-temperature expansion pot 11 is used to adjust the volume change of the cooling liquid of the cooling circuit in the range extender assembly, maintain the stability of the system pressure, and ensure efficient heat dissipation. The insurance box 12 is arranged in the third mounting area 10c and is closer to the cockpit 2 than the high-temperature expansion pot 11. The insurance box 12 is used to distribute power, protect circuits and electrical equipment, and prevent wire harness burning or fire caused by short circuit, overload or failure. The brake master cylinder booster 13 is arranged in the third mounting area 10c and is closer to the cockpit 2 than the high-temperature expansion pot 11. The brake master cylinder booster 13 can use the vacuum negative pressure generated by the electric vacuum pump to amplify the force of the driver stepping on the brake and finally transmit it to the wheel brake to achieve vehicle deceleration.
[0040] In the embodiment, the air intake system 7 in the front compartment 1 is arranged on the upper bent beam 101a, so that the arrangement space in the front compartment can be more compact, and the length of the front compartment 1 is effectively shortened. At the same time, the wind shield can be used to separate the heat dissipation assembly and the first mounting area 10a, the second mounting area 10b and the third mounting area 10c, so as to avoid the hot air in the first mounting area 10a, the second mounting area 10b and the third mounting area 10c overflowing to the front of the heat dissipation assembly, and solve the problems of high air intake temperature and poor heat dissipation effect.
[0041] Referring to Figure 5 andFigure 6 As shown, the range extender assembly 3 includes a range extender 31, a first suspension 32, a second suspension 33, and a third suspension 34, the range extender 31 extending in the length direction of the vehicle body 101, wherein the range extender 31 is defined to have two ends in the length direction and two sides in the width direction. The first suspension 32 is arranged at one end of the range extender 31, and the second suspension 33 and the third suspension 34 are arranged at the two sides of the range extender 31, respectively. The range extender 31 is mounted in the second mounting area 10b through the first suspension 32, the second suspension 33, and the third suspension 34. Specifically, the first suspension 32, the second suspension 33, and the front axle weldment are connected, and the third suspension 34 and the beam of the floor tunnel are connected. In this embodiment, the range extender 31 can be arranged in a longitudinal manner based on the traditional chassis and the structure of the vehicle body 101 according to the definition of the overall vehicle performance, and is fixed through a three-point suspension. The position and the attitude angle of the range extender 31 are determined in combination with the clearance between the range extender 31 and the surrounding steering mechanism, the lubrication and cooling system requirements of the range extender 31 itself, and the clearance requirement for power lifting assembly. For example, the range extender 31 itself requires that the elevation angle of the range extender be less than 5 degrees, and the transmission angle of the fuel vehicle power (the range extender is positioned in line with the engine of the fuel vehicle) is less than 3 degrees. The attitude angle (inclination angle 5 degrees, elevation angle 3.5 degrees, and swing angle 0.5 degrees) of the range extender is confirmed. At the same time, the range extender has the middle rod of the steering mechanism on the left side, the right beam and the cooling pipeline fixed on the beam on the right side, the steering mechanism below, and the water channel above. The lifting clearance and the mutual movement clearance requirement of the range extender and the surrounding components is 25 mm.
[0042] Referring to Figure 7 and Figure 8As shown, the vehicle charging power distribution assembly 4 includes a mounting bracket 41, a charging power distribution module 42, a high-voltage wire harness interface, a low-voltage wire harness interface, and a cooling pipeline interface (not shown in the figure). The mounting bracket 41 includes a bracket body 411, a first mounting portion 412, and a second mounting portion 413. The bracket body 411 is used to support and fix the charging power distribution module 42. The first mounting portion 412 and the second mounting portion 413 are respectively connected with the bracket body 411. The first mounting portion 412 is connected with the left front beam 101b, and the second mounting portion 413 is connected with the left curved beam 101c and the left side plate 101d, so that the charging power distribution module 42 can be installed in the third mounting area 10c through the mounting bracket 41. The high-voltage wire harness interface and the low-voltage wire harness interface are respectively arranged on the left side of the charging power distribution module 42, and the cooling pipeline interface is arranged at the front end of the charging power distribution module 42. The high-voltage wire harness interface is connected with the charging socket and the high-voltage power battery, the low-voltage wire harness interface is connected with the fuse box, and the cooling pipeline interface is connected with the cooling circuit of the heat dissipation assembly. According to the relative position of the charging power distribution module 42 and the front frame of the vehicle body, the mounting bracket 41 is designed to install the charging power distribution module 42 in this embodiment, that is, the charging power distribution module is installed by using a laminated structure (the charging power distribution module is connected with the vehicle body by using a laminated transition bracket). This can make the vehicle body structure simpler, the layout space more compact, and the assembly more convenient. While ensuring the performance of the charging power distribution module, it is also very beneficial to the assembly and post-sales human engineering convenience. At the same time, in order to avoid collision and extrusion of the wire end, the high-voltage wire harness interface and the low-voltage wire harness interface are all arranged on the side of the charging power distribution module facing the center of the front compartment. The low-voltage wire harness interface also adopts an upper and lower laminated design, which can reduce the size of the charging power distribution assembly.
[0043] After determining the arrangement position and attitude angle of the range extender assembly 3, the power supply and distribution assembly 4 is arranged in the left area in the front compartment 1, and the power supply and distribution assembly 4 is arranged in front of the left front wheel cover 101e of the vehicle 100, the high-voltage wire harness interface and the low-voltage wire harness interface of the power supply and distribution assembly 4 are arranged on the right side of the power supply and distribution module 42, and the cooling pipeline interface of the power supply and distribution assembly 4 is arranged in front of the power supply and distribution module 42, so that the following problems can be solved: a, avoiding the problem that the space of the trunk is small or the flatness is poor due to the arrangement of the power supply and distribution module in the trunk of the previous vehicle type, and avoiding the NVH problem existing in the arrangement of the power supply and distribution module under the co-driver seat. b, since the power supply and distribution module is arranged in front of the left front compartment, the battery, the range extender and the charging socket are all close, the length of the wire harness and the cooling pipeline is effectively shortened, and the whole vehicle cost is further reduced. At the same time, the front-engine front-drive transverse range extender application vehicle type is mostly passenger cars, the vehicle type is relatively wide, and the design is relatively easy, while the longitudinal rear-drive range extender application vehicle type is mostly commercial vehicles, the vehicle type is relatively narrow, the front compartment arrangement space is relatively small, the arrangement mode is more compact, and it is more difficult to realize the hybrid design. The front compartment arrangement method of the front-engine rear-drive plug-in range extender hybrid electric vehicle fully utilizes the arrangement boundary of each important part in the front compartment, and the range extender is arranged longitudinally, so that the front-engine rear-drive gasoline vehicle and the EV vehicle type can be simultaneously compatible, and multiple energy driving forms can be provided.
[0044] Referring to Figure 8 and Figure 9 As shown in the figure, the low-voltage battery assembly 5 includes a low-voltage battery module 51 and a fixed support 52, the fixed support 52 is fixed to the front plate welding member of the right front wheel cover 101h, and the low-voltage battery module 51 is connected with the fixed support 52. In this embodiment, the fixed support 52 is used to install the low-voltage battery module 51, so that the low-voltage battery module 51 can be more stably installed in the first installation area 10a.
[0045] Referring to Figure 10 As shown in the figure, the air intake system 7 includes an air intake system body 71 and a second installation foot 72, the second installation foot 72 is connected with the upper bent beam 101a, and the air intake system body 71 is connected with the second installation foot 72. In this embodiment, the air intake system 7 can be arranged on the upper bent beam 101a according to the position of the range extender 31, and the X-direction arrangement space of the front compartment is reasonably saved.
[0046] In a specific embodiment, the arrangement position and attitude angle of the range extender 31 can be determined according to the vehicle boundary and chassis hard point arrangement. Specifically, after the chassis hard point arrangement is completed, the positions of the steering machine, front axle weldment and swing arm weldment can be determined. The range extender is arranged above the steering machine, front axle weldment and swing arm weldment. The arrangement position and attitude angle of the range extender can be determined in combination with the vehicle boundary (and the positions of left and right girders and water channel), the transmission shaft included angle (the range extender is positioned in line with the oil vehicle engine). Then, the range extender 31 is installed. According to the arrangement position of the range extender 31 and the front compartment, the installation positions of the surrounding important components are determined and the corresponding important components are installed, such as the three-way catalyst 9, the range extender 31, the intake system 7, the low-voltage storage battery, the heat dissipation assembly 8, etc. Then, the charging and power distribution module 42 is arranged in the front left of the front compartment 1 in combination with the electromagnetic compatibility, vehicle collision requirements and the limited arrangement space factors of the front compartment 1, specifically before the left front wheel cover 101e and after the left front headlight 101f. Then, according to the vehicle collision requirements, the low-voltage storage battery is arranged on the right side of the range extender 31.
[0047] The longitudinal arrangement of the range extender 31 in the embodiment can be compatible with the front-engine rear-drive fuel vehicle and EV vehicle type, and can provide multiple energy driving forms. Because the powertrain arrangement of the front axle rear-drive fuel vehicle is also longitudinally arranged, the powertrain arrangement forms are consistent and the same, and the chassis hard point arrangement can be unified (when the power is transversely arranged, the steering machine position cannot be unified with the longitudinal power). The pure electric vehicle type and the hybrid vehicle with transversely arranged power or longitudinally arranged power can be compatible. At the same time, the charging and power distribution module 42 is optimally arranged in the left area of the front compartment 1. Unlike the previous hybrid vehicle, the pain point problem of being arranged on the vehicle body is solved, the pipeline cost is reduced, the vehicle performance and physical integration requirements are met, and the arrangement is optimized. In addition, the charging and power distribution module 42 is assembled by using a double-layer support structure. The mounting support is assembled on the left front girder, left bent beam and left side plate in priority. Then, the charging and power distribution module 42 is assembled on the vehicle body support, solving the difficult assembly problem of the vehicle.

Any changes or replacements within the technical range disclosed in the present application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
