Description

Technical Field

[0001] This application belongs to the field of vehicle manufacturing technology, and in particular relates to a front-end vehicle body module, engine compartment structure and front-end driving module. Background Technology

[0002] Currently, some new energy vehicles on the market use steering angle modules to replace the steering system of existing vehicles. The steering angle module integrates functions such as power, steering, braking and suspension, which greatly improves the vehicle's steering ability and greatly enhances the vehicle's maneuverability and handling.

[0003] The steering angle module is characterized by large-angle rotation, even allowing the wheels to spin in place. However, the powertrain of traditional fuel or pure electric vehicles is integrated into the engine compartment, resulting in a large span between the left and right longitudinal beams on both sides of the engine compartment in the Y direction. This makes it easy for the steering angle module to interfere with the large-angle rotation requirements of the steering angle module.

[0004] To avoid interference with the steering module, a design was adopted that reduced the span between the left and right longitudinal beams. However, this resulted in insufficient support due to the shortened span of the longitudinal beams, which in turn affected the body strength. Utility Model Content

The front end module of the crash beam includes a crash beam frame; the crash beam frame includes a front crossbeam, an energy-absorbing box, and a mounting seat; the energy-absorbing box is disposed on both sides of the front crossbeam in the Y direction and extends toward the front end module of the vehicle body in the X direction; the mounting seat is disposed at the rear end of the energy-absorbing box on both sides of the Y direction, and the mounting seats on both sides of the Y direction are connected to the front end module of the vehicle body.

[0012] In an optional embodiment of this application, the cabin structure further includes a subframe; the subframe is connected to the wheel arch bodies on both sides in the Y direction and is located below the wheel arch bodies.

[0013] In an optional embodiment of this application, the front end module of the anti-collision beam also includes a pedestrian lower leg protection beam; the pedestrian lower leg protection beam includes a front protection crossbeam and side beams, with the side beams located on both sides of the front protection crossbeam in the Y direction and extending toward the subframe to connect to the subframe.

[0051] Figure 1a This is a schematic diagram of a front-end driving module provided according to one embodiment of this application. Figure 1b for Figure 1a A schematic diagram of the front-end driving module in another state. Please refer to [link / reference]. Figure 1a and Figure 1b The front-end driving module includes at least a steering angle module and a cabin structure 10. Furthermore, the cabin structure 10 includes a front-end anti-collision beam module 600 and a front-end body module 1000.

[0052] Figure 2a for Figure 1a A schematic diagram of the front-end module 1000 of the vehicle body. Figure 2b for Figure 2a A schematic diagram of the front-end module 1000 of the vehicle body from another perspective. Please refer to... Figure 2a and Figure 2b The front-end module 1000 of the vehicle body includes a first crossbeam 1500, a second crossbeam 1600, and a wheel arch assembly.

[0053] The first crossbeam 1500 and the second crossbeam 1600 are arranged at intervals in the X direction. The wheel cover assembly is located on both sides of the first crossbeam 1500 and the second crossbeam 1600 in the Y direction and is connected to the first crossbeam 1500 and the second crossbeam 1600. The wheel cover assembly includes the wheel cover body and auxiliary longitudinal beams.

[0054] The wheel cover body includes a main longitudinal beam and a cover body. The cover body is located at the rear section of the main longitudinal beam and above the main longitudinal beam. The auxiliary longitudinal beam is connected to the front side of the cover body and extends forward, and is located above the main longitudinal beam in the Z direction.

[0055] Additionally, the steering angle module is connected to the engine compartment structure 10 and located below the wheel arch body. Specifically, the steering angle module is installed at the wheel arch body in the front body module 1000. Please refer to... Figure 1a and Figure 1b The wheel arch body of the front-end module 1000 provided in this application has sufficient space to allow the steering angle module to achieve 90° steering.

[0056] Figure 3 This is one of the exploded view diagrams of the front-end module 1000 of the vehicle body in 2a. Figure 4 for Figure 2a The second exploded view of the front-end module 1000 of the vehicle body.

[0057] Please see Figure 2a , Figure 3 and Figure 4 The wheel arch assemblies located on both sides of the first crossbeam 1500 and the second crossbeam 1600 in the Y direction are divided into a left wheel arch assembly 1100 and a right wheel arch assembly 1200.

[0058] Accordingly, the left wheel arch assembly 1100 includes a left wheel arch body 1110 and a left auxiliary longitudinal beam 1130, and the right wheel arch assembly 1200 includes a right wheel arch body 1210 and a right auxiliary longitudinal beam 1230. Further, the left wheel arch body 1110 includes a left main longitudinal beam 1111 and a left cover body 1112, and the right wheel arch body 1210 includes a right main longitudinal beam 1211 and a right cover body 1212.

[0059] To ensure sufficient space within the enclosure to allow the steering angle module to turn 90°, the left main longitudinal beam 1111 and the right main longitudinal beam 1211 are positioned further inward than the left and right longitudinal beams of existing conventional gasoline vehicles. Specifically, the Y-axis span between the left main longitudinal beam 1111 and the right main longitudinal beam 1211 is smaller than the Y-axis span between the left and right longitudinal beams of existing conventional vehicles. This results in a relatively larger coverage area for the enclosure, ensuring the wheels can rotate 90° and preventing wheel interference.

[0060] In addition, to reduce the impact of the reduced Y-axis span between the main longitudinal beams on the structural strength, auxiliary longitudinal beams are fixedly installed above the main longitudinal beams at the front of the cover. The left auxiliary longitudinal beam 1130 and the right auxiliary longitudinal beam 1230 increase the X-axis force transmission capacity of the front-end module 1000 of the vehicle body, ensuring the structural strength of the front-end module 1000 and giving it sufficient impact resistance.

[0061] It should be noted that in specific applications, the wheel cover body is manufactured using a one-piece molding process, that is, the cover body and the main longitudinal beam are molded as a single piece. Preferably, the wheel cover body is manufactured as a single piece using a casting process. This improves manufacturing efficiency and dimensional accuracy to a certain extent.

[0062] Furthermore, a corner module mounting interface for installing steering angle modules is formed on the top of the cover. The corner module mounting interface includes multiple holes for screws to pass through.

[0063] In some alternative embodiments, a corner module mounting interface for mounting a steering angle module is formed on the top of the wheel arch body. Specifically, the corner module mounting interface is located on the top of the wheel arch body.

[0064] exist Figure 3 In the embodiment shown, a left corner module mounting interface 1114 is formed on the top of the left cover 1112, and a right corner module mounting interface 1214 is formed on the top of the right cover 1212. The left corner module mounting interface 1114 is used to install the left steering angle module 20, and the right corner module mounting interface 1214 is used to install the right steering angle module 30.

[0065] Please combine Figure 1a and Figure 1b The steering angle module at the left wheel cover body 1110 is the left steering angle module 20, and the steering angle module at the right wheel cover body 1210 is the right steering angle module 30. Both can achieve 90° steering.

[0066] It should be noted that, in Figure 1a In the diagram, the left steering angle module 20″ is located at the 90° rotation position, while the left steering angle module 20′ is located at the rotation limit position in the other direction.

[0067] In a further optional embodiment, the front-end module 1000 of the vehicle body also includes wheel arch side beam assemblies, which are disposed on both sides of the second crossbeam 1600 in the Y direction and connected to the second crossbeam 1600 and the cover. The wheel arch side beam assemblies on both sides in the Y direction are located on the outer side of the wheel arch assemblies on both sides in the Y direction. The front section of the wheel arch side beam assembly protrudes from the cover and is located above the auxiliary longitudinal beam in the Z direction.

[0068] In this embodiment, the front-end module 1000 of the vehicle body also includes a wheel arch side beam assembly, which is positioned further outward in the Y direction than the wheel arch assembly.

[0069] The front section of the wheel arch side beam assembly protrudes from the arch body and is located above the auxiliary longitudinal beam. This, together with the main longitudinal beam and the auxiliary longitudinal beam, forms three X-direction force transmission paths, which greatly improves the safety of the entire vehicle.

[0070] exist Figure 3 and Figure 4 In the embodiment shown, the wheel arch side beam assemblies on both sides of the Y direction are the left wheel arch side beam assembly 1300 and the right wheel arch side beam assembly 1400, respectively. Thus, the left wheel arch side beam assembly 1300, the left main longitudinal beam 1111, and the left auxiliary longitudinal beam 1130 form three X-direction force transmission paths on the left side.

[0071] Correspondingly, the right wheel arch side beam assembly 1400, the right main longitudinal beam 1211, and the right auxiliary longitudinal beam 1230 form three X-direction force transmission paths on the right side.

[0072] In a further optional embodiment, the wheel arch side beam assembly includes a wheel arch side beam outer plate, a wheel arch side beam inner plate, and a second mounting plate for the anti-collision beam.

[0073] The outer and inner plates of the wheel arch side beam overlap in the Y direction, forming a front pillar interface and a sill beam interface at the rear end. The front pillar interface is located above the sill beam interface in the Z direction. The second mounting plate of the anti-collision beam is clamped between the front ends of the outer and inner plates of the wheel arch side beam.

[0074] In this embodiment, the left wheel arch side beam assembly 1300 and the right wheel arch side beam assembly 1400 have the same multi-plate overlapping structure. The left wheel arch side beam assembly 1300 includes a left wheel arch side beam outer plate 1310, a left wheel arch side beam inner plate 1320, and a left anti-collision beam second mounting plate 1330. The left wheel arch side beam outer plate 1310 and the left wheel arch side beam inner plate 1320 overlap in the Y direction, and the left anti-collision beam second mounting plate 1330 is clamped between the two front ends.

[0075] Correspondingly, the right wheel arch side beam assembly 1400 includes a right wheel arch side beam outer plate 1410, a right wheel arch side beam inner plate 1420, and a right anti-collision beam second mounting plate 1430. The right wheel arch side beam outer plate 1410 and the right wheel arch side beam inner plate 1420 overlap in the Y direction, and the right anti-collision beam second mounting plate 1430 is clamped between the two front ends.

[0076] In practical applications, the outer plate of the wheel arch side beam, the inner plate of the wheel arch side beam, and the second mounting plate of the anti-collision beam can be assembled by welding, but it is not limited to this.

[0077] In addition, the left wheel arch side beam assembly 1300 has a left front pillar interface 1301 and a left sill side beam interface 1302, and the right wheel arch side beam assembly 1400 has a right front pillar interface 1401 and a right sill side beam interface 1402.

[0078] In practical applications, the front pillar interface is used to install the front pillar (or A-pillar) of the upper vehicle body, and the sill side beam interface is used to install the sill side beam. In this way, the left A-pillar, the right A-pillar, the left sill side beam, and the right sill side beam can be installed at the corresponding interfaces on the left and right sides.

[0079] It should be emphasized that, since the steering angle module is generally driven by a motor and the drive shaft is eliminated, the overall height of the main longitudinal beam can be reduced. This reduces the height difference between the main longitudinal beam and the door sill beam in the Z direction, and reduces the bending moment caused by a collision.

[0080] In addition, the entire wheel arch side beam assembly extends smoothly forward and inward, which can form a small offset collision guidance feature, reduce the longitudinal impact on the wheel arch side beam, and protect the passenger compartment.

[0081] Please see Figure 4 In a further optional embodiment, the outer side of the cover is formed with a side beam overlap surface for overlapping with the inner plate of the wheel cover side beam.

[0082] In this embodiment, the outer Y-direction of the cover has a side beam lap surface for overlapping with the inner plate of the wheel arch side beam. In the illustrated embodiment, multiple holes are formed on the side beam lap surface, which allow connectors to pass through to achieve a cold connection with the inner plate of the wheel arch side beam. That is, the cover and the wheel arch side beam assembly are lapped together by a cold joining process (such as Self-Piercing Riveting (SPR), Flow Drill Screw (FDS), etc.).

[0083] In addition, the ends of the wheel arch side beam assembly and the second crossbeam 1600 are also connected by a cold-welding process. In specific applications, the overlapping surfaces of the second crossbeam 1600 and the side beams of the cover are connected to the wheel arch side beam assembly by a hot melt threaded connection (FDS) process.

[0084] exist Figure 4 In the embodiment shown, the side beam lap surface on the left cover 1112 is the left side beam lap surface 1113, and the side beam lap surface on the right cover 1212 is the right side beam lap surface 1213. The left side beam lap surface 1113 is connected to the inner plate 1320 of the left wheel cover side beam, and the right side beam lap surface 1213 is connected to the inner plate 1420 of the right wheel cover side beam.

[0085] Figure 5 This is a schematic diagram illustrating the assembly and collision force transmission path of the vehicle front-end module and the anti-collision beam 2000 according to one embodiment of this application. Please refer to... Figure 4 and Figure 5In a further optional embodiment, the wheel arch assembly also includes a first mounting plate and a third mounting plate for the anti-collision beam. The first mounting plate and the third mounting plate are respectively disposed at the front end of the main longitudinal beam and the front end of the auxiliary longitudinal beam.

[0086] The first mounting plate, the second mounting plate, and the third mounting plate of the anti-collision beam all have anti-collision beam mounting interfaces for mounting the anti-collision beam frame 2000.

[0087] In this embodiment, the front end of the left main longitudinal beam 1111 is provided with a first mounting plate 1120 for the left anti-collision beam, the front end of the right main longitudinal beam 1211 is provided with a first mounting plate 1220 for the right anti-collision beam, the front end of the left auxiliary longitudinal beam 1130 is provided with a third mounting plate 1140 for the left anti-collision beam, and the front end of the right auxiliary longitudinal beam 1230 is provided with a third mounting plate 1240 for the right anti-collision beam.

[0088] The first, second, and third mounting plates of the anti-collision beam are all provided with holes for fixing the anti-collision beam frame 2000. The first mounting plate of the anti-collision beam is located at the front end of the main longitudinal beam, the second mounting plate of the anti-collision beam is located at the front end of the wheel arch side beam assembly, and the third mounting plate of the anti-collision beam is located at the front end of the auxiliary longitudinal beam. In this way, the anti-collision beam frame 2000 can form three X-direction force transmission paths on the left and right sides.

[0090] In this embodiment, the subframe 500 can be installed at the bottom of the front end module of the vehicle body by means of multiple subframe mounting holes and screws.

[0091] exist Figure 6 and Figure 7As shown in the embodiment, the bottom wall of the left wheel arch body 1110 has three subframe left mounting holes 1151, 1152, and 1153 spaced apart along the X direction. The left and right sides of the subframe 500 are respectively provided with three subframe left mounting holes 511, 512, and 513 and three subframe right mounting holes 521, 522, and 523.

The three subframe right mounting holes 521, 522, and 523 can be aligned and engaged with the three right subframe mounting holes (not shown in the figure) on the bottom wall of the right wheel arch body 1210. Thus, the subframe 500 can be installed and fixed below the front end module 1000 of the vehicle body using screws.

[0092] Figure 8 for Figure 5 The diagram shows the anti-collision beam frame 2000. Please refer to the diagram. Figure 1a and Figure 8 In some optional embodiments, the front end module 600 of the anti-collision beam includes an anti-collision beam frame 2000, which includes a front crossbeam 2500, an energy-absorbing box, and a mounting base.

[0093] Energy-absorbing boxes are located on both sides of the front crossbeam 2500 in the Y direction and extend towards the front-end module 1000 of the vehicle body in the X direction. Mounting seats are located at the rear ends of the energy-absorbing boxes on both sides of the Y direction, and the mounting seats on both sides of the Y direction are connected to the front-end module 1000 of the vehicle body.

[0094] In this embodiment, the energy-absorbing boxes located on the left and right sides of the front crossbeam 2500 are a left energy-absorbing box 2300 and a right energy-absorbing box 2400, respectively. A left mounting base 2100 is fixedly installed at the rear end of the left energy-absorbing box 2300, and a right mounting base 2200 is fixedly installed at the rear end of the right energy-absorbing box 2400. That is, the mounting bases on both sides in the Y direction are a left mounting base 2100 and a right mounting base 2200, respectively.

[0095] The mounting brackets on both sides are connected to the main longitudinal beams, auxiliary longitudinal beams, and wheel arch side beam assemblies on both sides of the front module 1000 of the vehicle body.

[0096] Specifically, the left mounting base 2100 can be connected to the first mounting plate 1120 of the left anti-collision beam at the left main longitudinal beam 1111, the third mounting plate 1140 of the left anti-collision beam at the left auxiliary longitudinal beam 1130, and the second mounting plate 1330 of the left wheel arch side beam assembly 1300. The right mounting base 2200 can be connected to the first mounting plate 1220 of the right anti-collision beam at the right main longitudinal beam 1211, the third mounting plate 1240 of the right anti-collision beam at the right auxiliary longitudinal beam 1230, and the second mounting plate 1430 of the right anti-collision beam at the right wheel arch side beam assembly 1400.

[0097] In some optional embodiments, the cabin structure 10 further includes a subframe 500, which is connected to the wheel arch bodies on both sides in the Y direction and located below the wheel arch bodies. As mentioned above, the subframe 500 has multiple subframe side holes to match multiple subframe mounting holes on the bottom wall of the wheel arch body, thereby fixing the subframe 500 below the front end module 1000 of the vehicle body. Further details will not be repeated here.

[0098] Figure 9a This is a schematic diagram of the front-end module 600 of the anti-collision beam from one perspective. Figure 9b This is a schematic diagram of the front-end module 600 of the anti-collision beam from another perspective. Figure 10 for Figure 9a Exploded view of the front end module 600 of the middle anti-collision beam, and Figure 10 The document also includes a magnified view of point D. Please refer to [link / reference]. Figure 9a , Figure 9b and Figure 10 In some optional embodiments, the front end module 600 of the anti-collision beam also includes a pedestrian lower leg protection beam 400.

[0099] The pedestrian lower leg protection beam 400 includes a front protection crossbeam 410 and side beams. The side beams are located on both sides of the front protection crossbeam 410 in the Y direction and extend toward the subframe 500 to connect to the subframe 500.

[0100] In this embodiment, the side beams at both ends of the front protective beam 410 in the Y direction are the left beam 420 and the right beam 430, respectively. The front ends of the left and right sides of the subframe 500 are formed with front end interfaces, and correspondingly, the left front end interface 560 and the right front end interface 570 are formed. The left beam 420 and the right beam 430 are spliced ​​to the left front end interface 560 and the right front end interface 570, respectively.

[0101] In practical applications, the rear end of the side beam is provided with a side beam mounting plate for connecting to the front end interface of the subframe 500. Specifically, the rear ends of the side beams on both sides are the left beam mounting plate 460 and the right beam mounting plate 470, respectively. The left front end interface 560 includes three left front end holes 561, 562, and 563, and the right front end interface 570 includes three right front end holes 571, 572, and 573.

[0102] The left beam mounting plate 460 has three left mounting plate holes 461, 462, and 463, and the right beam mounting plate 470 has three right mounting plate holes 471, 472, and 473. The three left mounting plate holes 461, 462, and 463 can be aligned with the left front end holes 561, 562, and 563, and the three right mounting plate holes 471, 472, and 473 can be aligned with the three right front end holes 571, 572, and 573. The pedestrian lower leg protection beam 400 is then installed on the subframe 500 using bolts.

[0103] In a further optional embodiment, the front end module 600 of the anti-collision beam also includes a heat sink assembly 300, which includes a heat sink body 310 and mounting brackets. The mounting brackets are disposed on both sides of the heat sink body 310 in the Y direction and located at the top of the heat sink body 310. The bottom end of the heat sink body 310 is connected to the pedestrian lower leg protection beam 400, and the mounting brackets on both sides of the Y direction are correspondingly connected to the mounting seats on both sides of the Y direction.

[0104] In this embodiment, mounting brackets are provided on both sides of the top Y direction of the heat sink body 310. The mounting brackets on both sides are a left mounting bracket 100 and a right mounting bracket 200, respectively. The left mounting bracket 100 is connected to the left mounting base 2100, and the right mounting bracket 200 is connected to the right mounting base 2200.

[0105] In practical applications, a welded bracket is provided at the corner where the front protective beam 410 and the side beam meet, in order to connect the bottom end of the radiator body 310.

[0106] In the illustrated embodiment, the mounting bracket at the junction of the front protective beam 410 and the left beam 420 is a left welded bracket 440, which has a left bracket hole 441. The mounting bracket at the junction of the front protective beam 410 and the right beam 430 is a right welded bracket 450, which has a right bracket hole 451.

[0107] The top left and right corners and bottom left and right corners of the heat sink body 310 are provided with mounting pads. The mounting pad 341 can be inserted into the left bracket hole 441 and the mounting pad 351 can be inserted into the right bracket hole 451.

[0108] The mounting bracket has three bracket holes, arranged in a front-to-back two-to-back configuration. The left bracket hole 111 on the front end of the left mounting bracket 100 mates with the mounting pad 311, and the two left bracket holes 112 and 113 on the rear end of the left mounting bracket 100 mate with the left mounting base 2100. Correspondingly, the right bracket hole 221 on the front end of the right mounting bracket 200 mates with the mounting pad 321, and the two right bracket holes 222 and 223 on the rear end of the right mounting bracket 200 mate with the right mounting base 2200.

[0109] It should be understood that while securing the radiator body 310 with the four mounting pads 311, 321, 341, and 351, the vibration of the radiator body 310 during operation can be reduced.

[0110] As can be seen from the above, the anti-collision beam frame 2000 in the front-end module 600 of the anti-collision beam can be connected to the main longitudinal beam, auxiliary longitudinal beam and wheel arch side beam assembly on both sides of the front-end module 1000 of the vehicle body, so as to transmit the X-direction force to the rear simultaneously through three paths and ensure collision performance.

[0111] Secondly, it also integrates the radiator assembly 300 and the pedestrian lower leg protection beam 400. The pedestrian lower leg protection beam 400 serves as the lower support for the radiator assembly 300, and the top left and right sides are fixed with mounting brackets and mounting seats in the anti-collision beam 2000, which reduces the number of crossbeams used to fix the radiator assembly 300 and reduces the number of parts. Moreover, each connection point has a corresponding interface, which improves the utilization rate of parts, reduces the number of body components and welds, and lowers the overall vehicle cost.

[0112] In summary, since the front-end driving module has the aforementioned vehicle front-end module 1000, anti-collision beam front-end module 600, etc., it obviously has at least the following advantages brought by the above modules.

[0113] Firstly, the main longitudinal beam is moved inward until it avoids the 90° steering motion envelope of the wheel, thereby meeting the 90° large steering angle requirements of the wheel in the steering angle modular architecture vehicle. Furthermore, the traditional single longitudinal beam structure of the body is transformed into a multi-longitudinal beam structure to compensate for the insufficient support caused by the reduced span.

[0114] Secondly, the lower position of the main longitudinal beam reduces the Z-direction drop with the sill edge beam, thereby reducing the moment at the transition between the front longitudinal beam and the sill beam and minimizing bending deformation. Furthermore, it creates three X-direction force transmission paths, significantly enhancing the X-direction force transmission capacity of the longitudinal beam.

[0115] Third, the front-end module 600 of the anti-collision beam has a high degree of integration, which can reduce the number of parts and improve the utilization rate of the part structure.

[0116] Of course, this front-end driving module also has other advantages brought by the above modules, which will not be repeated here.

[0117] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
