[0047] Please refer to Figure 1 and Figure 2 This illustrates an embodiment of the automotive module provided by the present invention;
[0048] The vehicle module in this application includes a front platform module and a rear platform module that are arranged at the front and rear of the vehicle body and have the same structure. The front platform module can rotate 180° on a plane parallel to the floor of the vehicle body and translate to overlap with the rear platform module.
[0049] The front platform module is equipped with a front powertrain 101, and the rear platform module is equipped with a rear powertrain 102 corresponding to the front powertrain 101. The front powertrain 101 is inclined downward towards the front of the vehicle body and forms an angle with the horizontal plane. A pair of front drive shafts 103 are symmetrically arranged on both sides of the front powertrain 101, and a pair of rear transmission shafts 104 corresponding to the front drive shafts 103 are symmetrically arranged on both sides of the rear powertrain 102.
[0050] In practical applications, the rear platform module can be obtained by rotating the front platform module 180° on a plane parallel to the vehicle floor. That is, the rear powertrain 102 can be obtained by rotating and translating the front powertrain 101. The front powertrain 101 and rear powertrain 102 are selected identically, such as a 3-medium cooled EDU. 3-medium cooling means that the EDU is cooled by three different cooling media. In this solution, the three media are coolant, oil, and refrigerant. Multiple cooling media participate in powertrain cooling, improving cooling efficiency and ensuring the achievement of the vehicle's thermal management performance goals. A pair of front drive shafts 103 are symmetrically arranged on both sides of the front powertrain 101, and a pair of rear drive shafts 104 are symmetrically arranged on both sides of the rear powertrain 102. The rear drive shafts 104 can be obtained by rotating and translating the front drive shafts 103.
[0051] The rear EDU and rear drive shaft 104 are arranged by rotating and translating the front EDU and front drive shaft 103 to the corresponding position of the rear axle. The arrangement position and structural dimensions of the front drive shaft 103 can be determined together based on the vehicle attitude, ground clearance, tire model selection and drive shaft angle.
[0052] The front and rear powertrains 102 in this solution can rotate interchangeably, reducing the number of molds required, reducing costs, shortening the R&D and manufacturing cycle, promoting modular and universal design of the whole vehicle, improving the ease of assembly and disassembly, reducing R&D and manufacturing costs, and greatly enhancing the convenience of vehicle model expansion.
[0053] Furthermore, the front platform module is also provided with a pair of front suspensions 210 located on both sides of the vehicle body, and the rear platform module is provided with a pair of rear suspensions 220 corresponding to the pair of front suspensions 210.
[0054] The front suspension 210 includes at least a front steering knuckle, and a front upper control arm 211 and a front lower control arm 212 detachably disposed on one side of the front steering knuckle; the rear suspension 220 includes at least a rear steering knuckle, and a rear upper control arm 221 and a rear lower control arm 222 detachably disposed on one side of the rear steering knuckle; in this embodiment, the front steering knuckle and the rear steering knuckle are not shown in the figure, and one side of the front steering knuckle and the rear steering knuckle is fitted and fixed to the corresponding wheel hub assembly.
[0055] The front suspension 210 and rear suspension 220 in this solution have the same structure, both being double wishbone structures, and their hard points and structural dimensions are as similar as possible. The front suspension 210 and rear suspension 220 are rotatable and interchangeable. It can be considered that the front suspension 210 is rotated and translated to the corresponding position on the rear axle to obtain the rear suspension 220. The wheel center jump is driven by the swing arm to achieve the design goals of vehicle attitude and ground clearance. This can further promote the modular and universal design of the whole vehicle and improve the convenience of assembly and disassembly.
[0056] Furthermore, mounting holes are provided through the front lower control arm 212 and the rear lower control arm 222. A damping bracket is detachably installed at the bottom of the mounting hole, and a damping device 230 is detachably installed on the damping bracket. The mounting holes on the front lower control arm 212 and the rear lower control arm 222, and the damping bracket is detachably installed at the bottom of the mounting holes, can effectively reduce the Z-axis height of the suspension, which is convenient for the development of low-chassis vehicles.
[0057] Optional, such as Figure 3 As shown, a pair of mounting plates extend downward from the bottom of the mounting hole. The mounting plates protrude from the lower surface of the front lower control arm 212 or the rear lower control arm 222. The damping bracket is installed between the pair of mounting plates. The lower lug of the slide column passes through the mounting hole and is connected to the damping bracket. The upper lug of the slide column is connected to the longitudinal beam of the vehicle body.
[0058] Furthermore, a stabilizer bar assembly 240 is provided between a pair of front lower control arms 212, and a fixing hole is correspondingly provided on the pair of front lower control arms 212 to be connected to both ends of the stabilizer bar assembly 240. The stabilizer bar assembly 240 has the function of suppressing vehicle roll.
[0059] Furthermore, such as Figure 4 As shown, the front platform module is equipped with a front steering device 310, and the rear platform module is equipped with a rear steering device 320 corresponding to the front steering device 310, which is in the form of steer-by-wire. Optionally, both the front steering device 310 and the rear steering device 320 are rack-assisted steering devices (R-EPS). R-EPS is a motor that drives the rack shaft through a belt reduction mechanism and then through a ball screw pair. Its input end (the end connected to the steering wheel) is transmitted through a gear and rack transmission. The sensor outputs the steering wheel rotation signal to the motor, and the motor then completes the power assistance.
[0060] In another embodiment, a front steering device 310 is provided on the front platform module, and a rear steering device 320 corresponding to the front steering device 310 is provided on the rear platform module. The front steering device 310 is provided with an input shaft 311 that can be connected to the steering column, which is a conventional steering control state. The front steering device 310 and the rear steering device 320 rotate in the same direction.
[0061] Furthermore, such as Figure 5 As shown, the front platform module is also provided with a pair of front longitudinal beams 410 on both sides of the vehicle body, and the rear platform module is provided with a pair of rear longitudinal beams 420 corresponding to the pair of front longitudinal beams 410; the front upper control arm 211 and the front lower control arm 212 are detachably connected to the outer side of the front longitudinal beams 410; the rear upper control arm 221 and the rear lower control arm 222 are detachably connected to the outer side of the rear longitudinal beams 420.
[0062] Furthermore, the front platform module is also provided with a front suspension rear mounting crossbeam 411, and the rear platform module is provided with a rear suspension rear mounting crossbeam 421 corresponding to the front suspension rear mounting crossbeam 411.
[0063] The two ends of the front suspension rear mounting crossbeam 411 are perpendicularly connected to the inner rear half of a pair of front longitudinal beams 410, and the two ends of the rear suspension rear mounting crossbeam 421 are perpendicularly connected to the inner front half of a pair of rear longitudinal beams 420.
[0064] In one specific embodiment, the front platform module includes a left suspension mounting bracket, a right suspension mounting bracket, and a front suspension rear mounting crossbeam 411; the front longitudinal beam 410 includes a left front longitudinal beam 410 disposed on the left side of the vehicle body and a right front longitudinal beam 410 disposed on the right side of the vehicle body; one end of the left suspension mounting bracket is screwed to the inner side of the left front longitudinal beam 410, and the other end is fixedly connected to the left suspension; one end of the right suspension mounting bracket is screwed to the inner side of the right front longitudinal beam 410, and the other end is fixedly connected to the right suspension; both ends of the front suspension rear mounting crossbeam 411 are screwed to the inner sides of the left front longitudinal beam 410 and the right front longitudinal beam 410, respectively, and a rear suspension is connected to the front suspension rear mounting crossbeam 411.
[0065] Furthermore, a torque box mounting point 430 is provided at the bottom of the rear end of the front longitudinal beam 410. The torque box mounting point 430 is used for detachable installation of the torque box, which plays an important role in connecting and transmitting force.
[0066] To enhance vehicle scalability and embody modular design and assembly principles, the front and rear longitudinal beams, front and rear suspension mounting beams, and torsion box all utilize cast aluminum structures. By rationally planning the layout of each assembly within the front and rear compartments, the rotation of the front and rear longitudinal beams, the front and rear suspension mounting beams, and the inner mounting points of the torsion box are made identical.
[0067] Optionally, the front longitudinal beam 410 and rear longitudinal beam 420 in this solution are integrated longitudinal beam structures with a honeycomb structure, multiple mounting holes, aluminum alloy casting process, and integrated subframe function. The front end of the longitudinal beam is screwed to the energy-absorbing box, and the rear end is screwed to the torsion box.
[0068] Furthermore, both the upper front swing arm 211 and the lower front swing arm 212 are double wishbone structures that include a front fork and a rear fork; the front fork of the upper front swing arm 211 is connected to the front longitudinal beam 410, and the rear fork is connected to the torsion box; both the front fork and the rear fork of the lower front swing arm 212 are connected to the front longitudinal beam 410.
[0069] Optionally, the upper front control arm 211 is connected by a front ball joint and a rear bushing structure, while the lower front control arm 212 is connected by bushings at both the front and rear.
[0070] It should be noted that the installation methods of the rear upper control arm 221 and the rear lower control arm 222 in this application are the same as those of the front upper control arm 211 and the front lower control arm 212.
[0071] Optionally, the angle between the front powertrain 101 and the horizontal plane is 4-10°, and in one specific embodiment, the angle is 5°.
[0072] In another aspect, this application also provides a vehicle including the vehicle module.
[0073] The automotive module provided in this application has a rear platform module that can be obtained by rotating the front platform module 180° on a plane parallel to the vehicle floor. The arrangement position and structural dimensions of the front drive shaft 103 can be determined together based on the overall vehicle posture, ground clearance, tire model selection and drive shaft angle.
[0074] The front and rear powertrains 102, front and rear suspensions 220, front and rear steering devices 320, and front and rear driving modules in this solution can all rotate and be used interchangeably, reducing the number of molds to be developed, reducing cost investment, shortening the R&D and manufacturing cycle, promoting the modular and universal design of the whole vehicle, improving the ease of assembly and disassembly, reducing R&D and manufacturing cost investment, and greatly improving the convenience of vehicle model expansion.
[0075] In another embodiment, the vehicle module includes at least a front powertrain 101 and a rear powertrain 102;
[0076] The front powertrain 101 and the rear powertrain 102 are centrally symmetrical about the center point, which is the midpoint of the line connecting the structural center of the front powertrain 101 and the structural center of the rear powertrain 102.
[0077] It should be noted that there are certain differences in the front and rear structure of the vehicle module body. The center point here is not necessarily located at the exact center of the vehicle module chassis. The center point needs to be fitted based on the positions of the front powertrain 101 and the rear powertrain 102 so that the front powertrain 101 can reach the position of the rear powertrain 102 by rotating 180° around the center point.
[0078] A pair of front drive shafts 103 are symmetrically arranged on both sides of the front powertrain 101, and a pair of rear drive shafts 104 are symmetrically arranged on both sides of the rear powertrain 102; the pair of front drive shafts 103 and the pair of rear drive shafts 104 are centrally symmetrical about the center point.
[0079] In practical applications, the front powertrain 101 and the rear powertrain 102 are centrally symmetrical about the center point, that is, the rear powertrain 102 can be obtained by rotating and translating the front powertrain 101.
[0080] like Figure 1 As shown, a pair of front drive shafts 103 are symmetrically arranged on both sides of the front powertrain 101, and a pair of rear drive shafts 104 are symmetrically arranged on both sides of the rear powertrain 102; the front drive shafts 103 and the rear drive shafts 104 are centrally symmetrical about the center point, that is, the rear drive shafts 104 can be obtained by rotating and translating the front drive shafts 103.
[0081] It should be noted that, Figure 2 To facilitate observation of the distribution of the front powertrain 101 and the rear powertrain 102, a set of isometric views was selected. These views do not constitute a limitation on the positions of the front powertrain 101 and the rear powertrain 102. Figure 3-5 This does not constitute a limitation on the relative positions of the front and rear modules; the location of the center point is not shown in the attached diagram.
[0082] The location and structural dimensions of the front drive shaft 103 can be determined based on the vehicle's posture, ground clearance, tire type, and drive shaft angle. The mounting points of the front powertrain 101 and the rear powertrain 102 are the same, which facilitates universal design and installation.
[0083] In a specific embodiment, the front powertrain 101 and the front drive shaft 103 can be rotated 180° around the center point to reach the position of the rear powertrain 102 and the rear drive shaft 104. That is, the front drive shaft 103 on the left front rotates to the position of the rear drive shaft 104 on the right rear, and the front drive shaft 103 on the right front rotates to the position of the rear drive shaft 104 on the left rear. The rotation is universal, and the whole vehicle is modularly designed.
[0084] The front powertrain 101 and rear powertrain 102 in this solution can rotate interchangeably, reducing the number of molds required, reducing cost investment, shortening the R&D and manufacturing cycle, promoting modular and universal design of the whole vehicle, improving the ease of assembly and disassembly, reducing R&D and manufacturing cost investment, and greatly enhancing the convenience of vehicle model expansion.
[0085] Furthermore, it also includes a front suspension 210 and a rear suspension 220 with the same structure;
[0086] The front suspension 210 and the rear suspension 220 are centrally symmetrical about the center point;
[0087] Both sides of the front suspension 210 and the rear suspension 220 are equipped with a pair of wishbones, and the two ends of the wishbones are fixed to the vehicle body.
[0088] like Figure 3 As shown, the front suspension 210 and rear suspension 220 in this solution have the same structure and are centrally symmetrical about the center point. That is, the front suspension 210 and rear suspension 220 are rotatable and interchangeable, which can further promote the modular and universal design of the whole vehicle and improve the ease of assembly and disassembly.
[0089] A pair of wishbones are provided on both sides of the front suspension 210 and the rear suspension 220. The swing arms drive the wheel center to jump to achieve the design goals of the vehicle's posture and ground clearance.
[0090] Furthermore, it also includes a front steering device 310 and a rear steering device 320; the front steering device 310 and the rear steering device 320 are centrally symmetrically distributed about the center point, and the front steering device 310 and the rear steering device 320 are rotatable and interchangeable.
[0091] like Figure 4 As shown, the front steering device 310 and the rear steering device 320 have the same mounting interface, which facilitates installation and disassembly.
[0092] Furthermore, it also includes a front driving module and a rear driving module, and the front driving module and the rear driving module are centrally symmetrical about the center point;
[0093] Figure 2-5 The middle section is a side view of the relevant components, which only shows a comparison of the shapes of different components at the front and back. The related drawings do not constitute a limitation on their shape and relative position.
[0094] Furthermore, the front powertrain 101 is a front EDU; the front EDU is tilted downwards in a direction away from the vehicle body, and the angle between it and the horizontal plane is 4-10°.
[0095] Both the front and rear powertrains 102 are 3-medium cooled EDUs. An EDU is an electric drive unit with a motor and controller or a motor built into the transmission box. The front EDU is tilted forward by 4-10°, and the tilt angle can be adjusted appropriately according to the vehicle model. The arrangement position and structural dimensions of the front drive shaft 103 are determined based on the overall vehicle posture, ground clearance, tire model selection, and drive shaft angle. The arrangement position of the rear EDU and rear drive shaft 104 is obtained by rotating and translating the front EDU and front drive shaft 103 to the corresponding position of the rear axle. This rotation and translation can be understood as the front EDU and front drive shaft 103 directly rotating 180° around the center point to obtain the rear EDU and rear drive shaft 104.
[0096] Furthermore, the front suspension 210 includes a sliding column and a pair of wish arms disposed at both ends of the sliding column; the wish arms can rotate axially around the ends of the sliding column, and drive the wheel center to jump through the swing arms to achieve the design goals of vehicle attitude and ground clearance.
[0097] In another specific embodiment, the front suspension 210 includes an upper control arm, a lower control arm, and a shock absorber, without a subframe. The lower control arm is designed with a stabilizer bar connecting rod mounting hole for easy stabilizer bar connection. The stabilizer bar diameter varies depending on performance requirements. The upper control arm is fixed at two points: the front point is fixed to the longitudinal beam, and the rear point is connected to the torsion box. The lower control arm is also fixed at two points, both on the longitudinal beam. The upper point of the shock absorber is fixed to the longitudinal beam, and the lower point is connected to the lower control arm, effectively shortening the length of the shock absorber and adapting to the overall posture of more vehicle models.
[0098] The front suspension 210 and rear suspension 220 in this solution feature a highly common hardware design, enabling interchangeability between the two. By adjusting the stiffness and travel of the shock absorbers, the overall vehicle posture is ensured, while also taking into account the design space for coil springs and air springs, allowing the automotive module to be adapted to more vehicle models.
[0099] The integrated steer-by-wire system in the automotive module allows for flexible and diverse interior layouts, enabling larger interior spaces for the same vehicle model. This automotive module also accommodates the design of a non-steer-by-wire system. By modifying the flexible torque box structure and torque box connecting plate structure, and in conjunction with the design of the front bulkhead, a hardware interface for the non-steer-by-wire system is reserved on the front bulkhead, thus achieving a balance between steer-by-wire and non-steer-by-wire capabilities.
[0100] The automotive module simultaneously supports three steering functions. Depending on the vehicle model and available space, the rear-wheel steering can be flexibly adjusted to achieve three modes: no steering, adaptive steering, and four-wheel steering. When the rear wheels are not steering, standard EPS is used, enabling only front-wheel steering. When the rear wheels are adaptively steering, a steering angle of 10–15° can be achieved, improving the vehicle's passability and handling stability. In four-wheel steering mode, the rear wheels can achieve a steering angle of 30–40°, improving vehicle handling convenience at low speeds and enhancing vehicle handling stability at high speeds.
[0101] Furthermore, the front suspension 210 and rear suspension 220 share the same hard points, resulting in a higher degree of versatility.
[0102] The upper control arms of the front suspension 210 and the shock absorbers of the rear suspension 220 are arranged front and rear in the X direction. The lower end structure of the shock absorber is eliminated, reducing the Z-direction space utilization of the suspension system and forming a low-position double wishbone independent suspension system, achieving an ultra-low longitudinal beam. This design can accommodate the development of vehicles with high and low stances, increase the overall interior space of the vehicle, and improve the comfort brought by the large space to the occupants.
[0103] The rear and front driving modules share a common design, featuring symmetrical, integrated longitudinal beams that are universally compatible, working in conjunction with the steering system (four-wheel steering), drivetrain (four-wheel drive design), suspension system (four-wheel drive design), and other components. The front and rear suspension systems also share a common design, allowing for 180° horizontal rotation for installation. Vehicle posture can be adjusted by modifying the shock absorber stiffness and travel.
[0104] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
