Description

The layout and structure of the front compartment, the vehicle, and the layout method of the front compartment.

[0001] This application claims priority to Chinese Patent Application No. 202410794842.2, filed on June 19, 2024, entitled "Arrangement Structure of Front Compartment, Vehicle, Arrangement Method of Front Compartment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of automotive technology, specifically to a front compartment layout structure, a vehicle, and a front compartment layout method. Background Technology

[0003] In range-extended electric vehicles, there are generally two main layout structures. One involves placing the power generation assembly (engine + generator) in the front compartment and the drive motor in the rear compartment or the middle of the vehicle body. The other integrates the power generation assembly and the drive motor into a single drive assembly, with a small-power drive motor integrated into the transmission, and the drive assembly itself located in the front compartment. The first layout cannot achieve four-wheel drive. In the second layout, the drive motor has low power, and due to the constraints of the integrated structure and layout, it is difficult to install a high-power motor, making it unsuitable for off-road vehicles and Jeeps that require high power and operate in harsh conditions. Summary of the Invention

[0004] The following is an overview of the subject matter described in detail herein. This overview is not intended to limit the scope of the claims.

[0005] In view of this, this application aims to provide a front compartment layout structure that separately arranges the power generation assembly and the dual motor assembly on the subframe, making reasonable use of space and meeting the requirement that extended-range vehicles can also carry a high-power dual motor assembly in the front compartment, so as to meet the design requirements of new energy vehicles for four-wheel drive with a high-power four-wheel drive motor.

[0006] This application provides a front compartment layout structure, including a subframe, a power generation assembly, and a dual-motor assembly, wherein the power generation assembly and the dual-motor assembly are separately arranged;

[0007] The subframe includes an annular frame, and at least a portion of the dual-motor assembly is located within the annular frame and connected to the subframe; in the vehicle height direction, the power generation assembly is located above the subframe and the dual-motor assembly and is connected to the subframe.

[0008] In one possible implementation, a steering gear and a steering column are also included. The steering gear is fixed to the subframe and is located in front of the dual motor assembly in the length direction of the vehicle body and below the power generation assembly in the height direction of the vehicle body. The steering column is connected to the steering gear and passes between the power generation assembly and the dual motor assembly.

[0009] In one possible implementation, the subframe supports the power generation assembly via a four-point suspension structure, the four-point suspension structure comprising:

[0010] Two front lower mounts are located at the front end of the power generation assembly and are connected to the subframe from above.

[0011] Two side mounts, located on either side of the top of the power generation assembly, are used to connect to the vehicle body.

[0012] In one possible implementation, the front end of the dual-motor assembly is connected to the front suspension and the front crossbeam of the annular frame arranged along the length of the vehicle body. The drive shaft is located on both sides of the front end of the dual-motor assembly in the width direction of the vehicle body. A gap space is formed between the drive shaft, the front end and the front crossbeam for the support column to pass through. In the height direction of the vehicle body, the gap space is partially opposite to the power generation assembly so that the support column can be inserted into the gap space from below the subframe and support the power generation assembly.

[0013] In one possible implementation, the subframe also includes a support located in front of the annular frame, the support supporting and securing the steering gear, and supporting and connecting the front lower mount of the power generation assembly.

[0014] In one possible implementation, the support has a frame structure and a hollow area is formed between it and the steering gear for the support column to pass through. The hollow area is partially opposite to the power generation assembly in the vehicle height direction, so that the support column can pass through the hollow area from below the subframe to support the power generation assembly.

[0015] In one possible implementation, the support includes a first support section and a second support section arranged along the length of the vehicle body. The second support section extends downward at an angle relative to the first support section or is recessed. The front lower suspension is connected to the first support section. The steering gear is disposed on the second support section, supported by the second support section, and located below the front lower suspension.

[0016] In one possible implementation, the subframe includes two longitudinal beams spaced apart and extending along the length of the vehicle body, and a first crossbeam, a second crossbeam, and a third crossbeam located between the two longitudinal beams and arranged in sequence. The front sections of the first crossbeam and the two longitudinal beams form a support portion, and the main sections of the second crossbeam, the third crossbeam, and the two longitudinal beams enclose an annular frame.

[0017] In one possible implementation, the lower front suspension includes:

[0018] The first bracket is connected to the power generation assembly and has a connecting shaft arranged along the height of the vehicle body;

[0019] The second bracket, supported by and connected to the subframe, has a suspension bushing through which the connecting shaft passes.

[0020] This application also provides a vehicle, characterized in that it includes a vehicle body, a front compartment is formed on the vehicle body, and the front compartment has the arrangement structure of the front compartment as described above.

[0021] This application also provides a method for arranging the forward compartment, including the following steps:

[0022] The dual-motor assembly is connected to the subframe, and its front mount is set along the length of the vehicle body, with a clearance space between the drive shaft and the crossbeam where the front mount is located.

[0023] The steering gear is fixed to the subframe, with the steering gear positioned in front of the dual motor assembly along the length of the vehicle body, and a hollow area between the steering gear and the subframe through which the support column passes.

[0024] Connect the steering column to the steering gear and position the steering column above the dual motor assembly;

[0025] The support columns are inserted into the gap space and the hollow area respectively;

[0026] The power generation assembly is positioned above the dual motor assembly and the subframe, and is supported by support columns.

[0027] The subframe, dual motor assembly, generator assembly, steering gear, and steering column are lifted together into the front compartment using a lifting mechanism, and the subframe is then installed onto the vehicle body.

[0028] The front compartment layout structure provided in this application arranges the power generation assembly and the dual motor assembly in a separate structure in the front compartment, and makes reasonable arrangements to improve the utilization rate of the front compartment space, increase the size and power of the motors, and achieve the purpose of increasing the power of the front drive motor on the basis of the whole vehicle four-wheel drive. This meets the requirements of the vehicle's four-wheel drive and the front compartment is equipped with a high-power drive motor, improves the driving performance of electric drive vehicles, and enables the requirement that high-power vehicles such as off-road vehicles and jeeps can also be set as four-wheel drive electric drive vehicles.

[0029] After reading and understanding the accompanying diagrams and detailed descriptions, the other aspects can be understood. Attached Figure Description

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] First, it's important to clarify that spatial terminology such as "front," "front end," and "above" are used to describe the product's actual orientation during use. The "front-to-back" direction refers to the length of the vehicle body, from front to back (from the front to the rear). "Front end" and "front end" refer to the side closer to the front of the vehicle. The "vertical" direction refers to the height of the vehicle body.

[0040] Please refer to Figures 1-7. This application provides a front compartment layout structure, including a subframe 1, a power generation assembly 5, and a dual-motor assembly 2. The power generation assembly 5 includes a generator and an engine, and the dual-motor assembly 2 includes two motor assemblies. Each motor assembly includes a drive motor for driving the wheels and a transmission. The dual-motor assembly 2 is connected to the wheels via a drive shaft 7. In this application, the power generation assembly 5 and the dual-motor assembly 2 are separately arranged, with the transmission and drive motor integrated, while the power generation assembly 5 integrates the engine and generator. This separate arrangement facilitates separate placement in the front compartment, improves the space utilization and occupancy rate of the front compartment, and increases the space occupied by the drive motor, thereby increasing the size and power of the installed drive motor.

[0041] The subframe 1 includes an annular frame, and at least a portion of the dual-motor assembly 2 is located within the annular frame and connected to the subframe 1 via a first suspension structure. The power generation assembly 5 is connected to the subframe 1 via a second suspension structure. Furthermore, in the height direction of the vehicle body 9, the power generation assembly 5 is located above both the subframe 1 and the dual-motor assembly 2. Thus, with these two components arranged separately, the dual-motor assembly 2 no longer needs to be directly opposite the power generation assembly 5; that is, the dual-motor assembly 2 is not located directly below the power generation assembly 5, but can be staggered. For example, the dual-motor assembly 2 can be moved forward or backward relative to the power generation assembly 5 in the length direction of the vehicle body 9, increasing the space occupied and utilized in the front compartment, thereby increasing the size and power of the motors and achieving the goal of simultaneously increasing the power of the front drive motor while maintaining the vehicle's four-wheel drive capability.

[0042] Specifically, the dual-motor assembly 2 can be moved towards the rear of the vehicle relative to the power generation assembly 5, and is staggered with the power generation assembly 5. As shown in Figure 1, the steering gear 3 is located in front of the dual-motor assembly 2, and the power generation assembly 5 is located above the front ends of the steering gear 3 and the dual-motor assembly 2. The steering column 4 is connected to the steering gear 3 and extends obliquely upward and backward through the space between the power generation assembly 5 and the dual-motor assembly 2.

[0043] This configuration places the generator assembly 5 and the dual-motor assembly 2 in a separate structure in the front compartment, with one located above the steering column 4 and the other below it. This layout is reasonable and compact, improving the utilization of the space below the steering column 4. This arrangement increases the space occupied by the motors, allowing for larger motors and higher power output. It achieves the goal of increasing the power of the front drive motor while maintaining the vehicle's four-wheel drive capability. This meets the requirements of four-wheel drive vehicles with a high-power drive motor in the front compartment, improving the driving performance of electric vehicles. It also enables high-power vehicles such as off-road vehicles and jeeps to be configured as four-wheel drive electric vehicles.

[0044] The power generation assembly 5 is mounted above the subframe 1 via a second suspension structure, which is a four-point suspension structure. Supported by this four-point suspension, the power generation assembly 5 is positioned entirely above the subframe 1 with a gap between it and the subframe 1, and is located above the steering gear 3 and the front end of the dual-motor assembly 2. In other words, the four-point suspension structure supports the power generation assembly 5 above the front end of the dual-motor assembly 2, the subframe 1, and the steering gear 3.

[0045] The four-point suspension structure includes two front lower suspensions 51 and two side upper suspensions 52. The two front lower suspensions 51 are located at the front end of the power generation assembly 5, connected to the subframe 1 from above; that is, the two front lower suspensions 51 are connected to the top surface of the subframe 1. The two side upper suspensions 52 are located on both sides of the top of the power generation assembly 5 and connected to the vehicle body 9. For example, the side upper suspensions 52 are connected to the towers of the shock absorbers 8 mounted on the vehicle body 9. The shock absorbers 8 are mounted on the front suspension 6, which is connected to both sides of the subframe 1 in the width direction of the vehicle body 9. The towers of the shock absorbers 8 are connected to the top of the power generation assembly 5 via the side upper suspensions 52, thus securing the upper end of the power generation assembly 5. The front lower suspensions 51 are positioned at the front end of the power generation assembly 5, rather than at the rear end, to avoid interference with the arrangement of the dual-motor assembly 2.

[0046] This application also provides a specific structure of a front lower suspension 51, as shown in Figure 7. The front lower suspension 51 includes a first bracket 511 and a second bracket 512. The first bracket 511 is connected to the power generation assembly 5 and has a connecting shaft 5111 arranged along the height direction of the vehicle body 9. The second bracket 512 is supported by the subframe 1 (as shown in Figure 7, specifically by the longitudinal beam 11 of the subframe 1, such as the front section 111 of the longitudinal beam 11) and connected to the subframe 1. The second bracket 512 has a suspension bushing through which the connecting shaft 5111 passes. In this way, the first bracket 511 can be directly inserted downward into the second bracket 512 to achieve connection, which is simple and provides stable support.

[0047] The dual-motor assembly 2 includes a motor body 21, a motor controller 22, and a transmission 23. The motor controller 22 can be located in front of, above, or behind the motor body 21. In a preferred embodiment, as shown in FIG2, the motor controller 22 is located behind the motor body 21 (the side closer to the front of the vehicle body 9 in the length direction is considered front, and the side closer to the rear of the vehicle body 9 is considered rear). In this application, the transmission 23 is located in front of the motor body 21 in the length direction of the vehicle body 9. The first suspension structure can also be a four-point suspension, including two front suspensions and two rear suspensions. The two front suspensions are located at the front end of the dual-motor assembly 2 and are arranged along the length direction of the vehicle body 9, and the two rear suspensions are located at the rear end of the dual-motor assembly 2 and are arranged along the width direction of the vehicle body 9. The front suspensions are located on the front side of the dual-motor assembly 2 facing the front of the vehicle body, i.e., in front of the transmission 23. As shown in FIG5, the front end of the dual-motor assembly 2 (i.e., the transmission 23) is connected to the drive shaft 7 and is connected to the front crossbeam of the annular frame (13 in the figure, the second crossbeam 13 in the following embodiment) through the front suspensions. The driveshaft 7 is located on both sides of the transmission 23 in the width direction of the vehicle body 9. A gap space 101 is formed between the driveshaft 7, the transmission 23, and the front crossbeam (i.e., the second crossbeam 13) of the annular frame. As shown in Figure 5, the driveshaft 7 and the front crossbeam (i.e., the second crossbeam 13) of the annular frame are spaced apart in the length direction of the vehicle body 9, and the side of the transmission 23 and the longitudinal beam 11 of the annular frame are spaced apart. Thus, on both sides of the transmission 23, the transmission 23, the driveshaft 7, the front crossbeam of the annular frame, and the longitudinal beam 11 each enclose a gap space 101. At the same time, two gap spaces 101 are partially opposite to the generator assembly 5 in the height direction of the vehicle body 9. Therefore, during assembly, the dual motor assembly 2, the steering gear 3, the steering column 4, and the generator assembly 5 can be installed on the subframe 1, and a support column can be inserted from below the subframe 1 into the gap space 101 to hold the generator assembly 5 in place. The support column supports the generator assembly 5, allowing it to remain balanced and be lifted together with the subframe 1. Therefore, during assembly, the power generation assembly 5 can be installed on the subframe 1 first (specifically, the power generation assembly 5 can be placed on top of the subframe 1, and the front lower suspension 51 of the power generation assembly 5 can be connected to the subframe 1). The power generation assembly 5 is balanced by the support of the support column, so that the power generation assembly 5, the subframe 1, the dual motor assembly 2, the steering gear 3, etc. can be lifted together by the same lifting mechanism and moved into the front compartment of the vehicle body 9 as a whole. Then, the subframe 1 and the vehicle body 9 can be connected to complete the assembly.

[0048] This assembly method is very simple. Compared with the existing technology, which first installs the subframe 1 into the front compartment by lifting, and then lowers the power generation assembly 5 or drive assembly into the front compartment by hoisting, and then connects it to the subframe 1, this application does not require hoisting again, simplifying the assembly process, saving assembly links and steps, improving production efficiency, and saving production costs. Moreover, the two suspensions of the power generation assembly 5 (such as the two front lower suspensions 51) are first connected to the subframe 1 outside the vehicle body 9. After the whole assembly is placed into the front compartment, only the remaining two suspensions (such as the two side upper suspensions 52) need to be connected to the vehicle body 9, as well as the subframe 1 and the vehicle body 9. Compared with connecting the power generation assembly 5 and the subframe 1 in the front compartment of the vehicle body 9, the connection operation is simpler and faster, further improving production efficiency.

[0049] To ensure the balance of the power generation assembly 5 during the lifting process with the subframe 1 and to prevent the power generation assembly 5 from swaying or tilting and affecting the assembly, the power generation assembly 5 can be supported by three points. Two support columns can be inserted into the two gap spaces 101 on both sides of the transmission, while a third support column can pass through the gap between the front side of the annular frame, the steering gear 3, and the subframe 1 to support the power generation assembly 5.

[0050] In one embodiment, the subframe 1 further includes a support portion 10 located in front of the annular frame. The support portion 10 supports and fixes the steering gear 3, and the front lower suspension 51 of the power generation assembly 5 is located above the support portion 10 and connected to the support portion 10. In this way, the front end of the subframe 1 simultaneously supports the steering gear 3 and the power generation assembly 5. The steering gear 3 is arranged below the front lower suspension 51 of the power generation assembly 5, which not only makes the steering gear 3 close to the transmission, facilitating the connection between the steering column 4 and the steering gear 3, but also does not occupy additional space in the length direction of the vehicle body 9; it has a compact structure and optimizes the space layout.

[0051] To facilitate the passage of the third support column, the support part 10 may have a frame structure and a hollow area 102 for the support column to pass through between it and the steering gear 3; the hollow area 102 is partially opposite to the power generation assembly 5 in the height direction of the vehicle body 9, so that the support column can pass through the hollow area 102 from below the subframe 1 to support the power generation assembly 5.

[0052] Furthermore, the support portion 10 includes a first support section 1111 and a second support section 1112 arranged along the length of the vehicle body 9. The second support section 1112 is inclined downward or recessed relative to the first support section 1111. The second support section 1112 is connected to the first support section 1111 and the annular frame, respectively. The steering gear 3 is disposed on the second support section 1112 and located below the front lower suspension 51. One end of the front lower suspension 51 is located in front of the steering gear 3, such as above and connected to the first support section 1111 and supported by the first support section 1111. The other end is located behind the steering gear 3, which may be located above the area where the second support section 1112 and the main section 112 of the longitudinal beam 11 are connected, or above the main section 112, such as above the area where the main section 112 is close to the second support section 1112.

[0053] In one specific embodiment, as shown in FIG5, the subframe 1 includes two longitudinal beams 11 spaced apart in the width direction of the vehicle body 9 and extending along the length direction of the vehicle body 9, and a first crossbeam 12, a second crossbeam 13, and a third crossbeam 14 arranged sequentially between the two longitudinal beams 11. The first crossbeam 12 and the front section 111 of the two longitudinal beams 11 form a support portion 10. The first crossbeam 12 forms a first support section 1111, or a portion of the beam segment of the front section 111 of the longitudinal beam 11 forms a first support section 1111. The remaining beam segment of the front section 111 of the longitudinal beam 11 forms a second support section 1112. The area between the first crossbeam 12 and the front section 111 of the two longitudinal beams 11 is a hollow area 102. The second crossbeam 13, the third crossbeam 14, and the main section 112 of the two longitudinal beams 11 enclose an annular frame. The second crossbeam 13 forms the front crossbeam of the aforementioned annular frame and is connected to the front suspension of the dual motor assembly 2. The third crossbeam 14 forms the rear crossbeam of the annular frame.

[0054] The dual-motor assembly 2 may have two symmetrically arranged rear mounts, both of which may be arranged along the width direction of the vehicle body 9. For example, the rear end of the dual-motor assembly 2 (the area where the motor body 21 is located) has a rear protruding shaft extending in the width direction of the vehicle body 9, and a rear mount bushing is embedded in the longitudinal beam 11 of the subframe 1. The rear protruding shaft is inserted into the rear mount bushing and connected to the subframe 1 by screwing.

[0055] An embodiment of this application also provides a vehicle, including a vehicle body 9, which may be a monocoque vehicle body. A front compartment is formed on the vehicle body 9, and the front compartment has the arrangement structure of the front compartment as described in the above embodiments. This vehicle then has the beneficial effects described in the above embodiments, which will not be elaborated further here.

[0056] Embodiments of this application also provide a method for arranging the forward compartment, applicable to the arrangement structure described in the above embodiments, the method comprising the following steps:

[0057] Connect the dual motor assembly 2 to the subframe 1 and set its front suspension along the length of the vehicle body 9, so that there is a gap space 101 between the drive shaft 7 and the front crossbeam of the annular frame where the front suspension is located.

[0058] The steering gear 3 is fixed to the subframe 1, so that the steering gear 3 is located in front of the dual motor assembly 2 in the length direction of the vehicle body 9, and there is a hollow area 102 between the steering gear 3 and the subframe 1 for the support column to pass through.

[0059] Connect the steering column 4 to the steering gear 3 and position the steering column 4 above the dual motor assembly 2;

[0060] The support columns are inserted into the gap space 101 and the hollow region 102, respectively.

[0061] The power generation assembly 5 is positioned above the dual motor assembly 2 and the subframe 1, and is supported by support columns.

[0062] The subframe 1, dual motor assembly 2, generator assembly 5, steering gear 3, and steering column 4 are lifted together into the front compartment using a lifting mechanism, and the subframe 1 is then installed onto the vehicle body 9.

[0063] The order of the above steps can be changed and is not limited to a single sequence. Specifically, it can be done by first placing the subframe 1 on the lifting platform of the lifting mechanism; then assembling the dual-motor assembly 2 onto the subframe 1 using the above steps, positioning the support column within the gap space 101 and the hollow area 102 (this can be done by assembling the dual-motor assembly 2 first and then inserting the support column, or by fixing the support column to the lifting platform, then placing the subframe 1 and the dual-motor assembly 2 onto the lifting platform for positioning, so that the support column is positioned to form the gap space 101 and the hollow area 102; after assembling the dual-motor assembly 2 onto the subframe 1, the support column will naturally be positioned within the gap space 101 and the hollow area 102). When placing the generator assembly 5 onto the lifting platform, positioning it allows the support column to support the generator assembly 5. Additional support columns can also be arranged to support the dual-motor assembly 2. For example:

[0064] At least three first support columns and at least three second support columns shall be installed on the lifting platform;

[0065] Corresponding to the positions of the first and second support columns, the subframe 1 is placed on the lifting platform of the lifting mechanism;

[0066] The dual-motor assembly 2 is connected to the subframe 1 and supported by the first support column; and at least one second support column is inserted into the gap space 101 formed by the drive shaft 7, the front crossbeam of the annular frame, the longitudinal beam 11, and the dual-motor assembly 2.

[0067] The steering gear 3 is fixed to the subframe 1, so that the steering gear 3 is located in front of the dual motor assembly 2 in the length direction of the vehicle body 9, and at least one second support column is inserted into the hollow area 102 formed between the steering gear 3 and the subframe 1.

[0068] Connect the steering column 4 to the steering gear 3 and position the steering column 4 above the dual motor assembly 2;

[0069] The power generation assembly 5 is positioned above the dual motor assembly 2 and the subframe 1, and is supported by the second support column;

[0070] Connecting the front lower suspension 51 of the power generation assembly 5 and the subframe 1;

[0071] The subframe 1, dual motor assembly 2, generator assembly 5, steering gear 3, and steering column 4 are lifted together into the front compartment using a lifting mechanism, and the subframe 1 is then installed onto the vehicle body 9.

[0072] It should be noted that the above steps are not limited in any particular order.

[0073] The assembly of the front compartment using the above method is very simple. Compared with the existing technology, which first installs the subframe 1 into the front compartment by lifting, and then lowers the power generation assembly 5 or drive assembly into the front compartment by hoisting, and then connects it to the subframe 1, this application does not require hoisting again, simplifying the assembly process, saving assembly links and steps, improving production efficiency, and saving production costs. Moreover, the power generation assembly 5 is first connected to the subframe 1 outside the vehicle body 9. After the whole assembly is placed into the front compartment, only the connection between the power generation assembly 5 and the vehicle body 9 and the subframe 1 and the vehicle body 9 need to be performed. Compared with the connection between the power generation assembly 5 and the subframe 1 inside the front compartment of the vehicle body 9, the connection operation is simpler and faster, further improving production efficiency.
