Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0047] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0048] The vehicle frame includes a front longitudinal beam 100 and a front panel 300 , and the front longitudinal beam 100 is connected to the front panel 300 . When the vehicle is hit, the front longitudinal beam 100 can collapse to absorb energy, reducing the possibility of injury to personnel or damage to the battery.

[0049] However, the existing front panel 300 is not rigid enough. When the energy cannot be fully absorbed, the front cabin intrusion is large, and the risk of personnel injury and battery damage is high.

[0050] In order to solve the technical problems of insufficient rigidity of the front panel 300, large intrusion into the front cabin, and high risk of injury to personnel and damage to batteries, the first embodiment of the present application provides a frame, see Figure 1 and Figure 2 The vehicle frame includes a front longitudinal beam 100, an A-pillar 200 and a front enclosure 300; the front enclosure 300 includes a main body portion 310 and a reinforcement portion 320. The main body portion 310 is arranged between the A-pillars 200 and is respectively connected to the A-pillars 200. The reinforcement portion 320 is connected to the main body portion 310 and protrudes from the main body portion 310 toward the direction close to the front longitudinal beam 100. The reinforcement portion 320 is connected to the front longitudinal beam 100, and both ends of the reinforcement portion 320 are connected to the A-pillars 200.

[0051] Specifically, the main body portion 310 and the reinforcement portion 320 are parts of the front enclosure 300 , and the main body portion 310 and the reinforcement portion 320 are an integrated structure.

[0052] Specifically, the front wall 300 is disposed between the two A-pillars 200 along the left-right direction and respectively connects the two A-pillars 200 ; the reinforcement portion 320 is disposed between the two A-pillars 200 along the left-right direction and respectively connects the two A-pillars 200 .

[0053] Specifically, the vehicle frame includes at least two front longitudinal beams 100 , which are spaced apart in the left-right direction and respectively connected to the front of the front enclosure 300 .

[0054] It is understood that, in some embodiments, referring to the figures, the front wall 300 protrudes toward the front longitudinal beam 100 to form an arch shape. Specifically, the middle portion of the front wall 300 in the left-right direction is located further forward than the two ends.

[0055] Since the reinforcement portion 320 is arranged between the two A-pillars 200 and connects the two A-pillars 200 respectively, and the reinforcement portion 320 is formed by part of the front panel 300, the middle portion of the reinforcement portion 320 in the left and right direction also protrudes toward the front longitudinal beam 100 following the front panel 300 to form an arch.

[0056] Specifically, since the reinforcement portion 320 is formed by a portion of the front panel 300 protruding toward the front longitudinal beam 100 , it means that the reinforcement portion 320 is an inseparable part of the front panel 300 , which can make the reinforcement portion 320 more rigid.

[0057] First, in the above embodiment, by providing a reinforcement portion 320 on the front panel 300 to improve the rigidity of the front panel 300, the risk of the front panel 300 intruding more into the front cabin during a collision due to its poor rigidity is reduced, thereby improving the safety performance of the vehicle frame.

[0058] Secondly, in the above-described embodiment, the protruding reinforcement portion 320 further enhances the performance of the reinforcement portion 320, thereby providing greater rigidity. This further reduces the risk of the front panel 300 intruding into the front compartment during a collision due to its poor rigidity, thereby improving the safety performance of the vehicle frame. Furthermore, the reinforcement portion 320 formed by the partial protrusion of the front panel 300 also reduces the total number of components in the front panel 300, reducing the possibility of rigidity degradation due to connection instability, further improving the rigidity of the vehicle frame. Furthermore, reducing the number of components also reduces the weight of the front panel 300, thereby improving the performance of the vehicle frame.

[0059] Thirdly, in the above embodiment, by providing a reinforcement portion 320 that simultaneously connects the front longitudinal beam 100 and the A-pillar 200, when the front longitudinal beam 100 is hit, the reinforcement portion 320 can allow part of the energy to bypass the passengers and the battery and be transferred to the A-pillar 200. As a result, the portion of the frame behind the A-pillar 200 can share part of the energy, thereby reducing the amount of intrusion into the front cabin after the collision and further improving the safety performance of the frame.

[0060] In some embodiments, see Figure 1 and Figure 2 The main body 310 has an installation space 311 on a side away from the front longitudinal beam 100 . The main body 310 also has an installation hole 312 . The installation hole 312 passes through the main body 310 and communicates with the installation space 311 .

[0061] In some embodiments, both the installation space 311 and the installation hole 312 are used to set up and install the steering gear.

[0062] In the above example, see Figure 3 and Figure 4 By setting the installation space 311 and the installation hole 312 on the main body 310, the installation space 311 and the installation hole 312 can avoid the reinforcement part 320, so that the reinforcement part 320 has a complete structure in the left and right directions, the rigidity of the reinforcement part 320 is improved, and the possibility of the reinforcement part 320 being bent or even broken by force is reduced, thereby improving the rigidity of the front wall 300 and the frame, and further improving the safety performance of the front wall 300 and the frame.

[0063] In some embodiments, see Figure 3 and Figure 4 The reinforcement portion 320 has a groove 321 on a side facing away from the front longitudinal beam 100 . The groove 321 and the installation space 311 are arranged at different positions and communicate with each other.

[0064] In some embodiments, the surface of the front panel 300 facing away from the front longitudinal beam 100 is recessed toward the front longitudinal beam 100 , and the surface of the front panel 300 facing the front longitudinal beam 100 protrudes toward the front longitudinal beam 100 to form a reinforcement portion 320 , and the groove 321 is formed at the recessed portion, and the groove 321 has groove walls that are opposite to each other in the up and down directions.

[0065] In some embodiments, the installation space 311 passes through the groove wall located below, that is, the groove 321 and the installation space 311 are connected in the up and down directions.

[0066] In some embodiments, the surface with the mounting hole 312 is disposed opposite to the upper slot wall in the up-down direction.

[0067] Firstly, by making the reinforcement portion 320 protrude and forming the groove 321 to form a hollow beam structure, it is possible to increase the local strength and form the reinforcement portion 320 under the premise of the integrated front enclosure 300.

[0068] Secondly, in the above embodiment, the groove 321 is provided to communicate with the installation space 311 to expand the operating space when installing the steering gear, thereby reducing the difficulty of assembling the vehicle including the frame.

[0069] Thirdly, by providing the groove 321 to communicate with the installation space 311, a portion of the steering gear can be disposed in the groove 321 after installation, allowing the front panel 300 to reduce the size of the installation space 311 while ensuring that the steering gear can be installed, thereby further improving the rigidity of the front panel 300 and reducing the amount of intrusion into the front cabin after a collision, thereby improving the safety performance of the rigidity of the frame.

[0070] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The frame also includes a middle beam 400 and a side beam 500, which are arranged at intervals; a portion of the main body 310 protrudes in a direction away from the front longitudinal beam 100, and forms an inclined surface 313 on the side away from the front longitudinal beam 100, the middle beam 400 is connected to the inclined surface 313, and the side beam 500 is connected to the inclined surface 313.

[0071] In some embodiments, the vehicle frame includes at least two side beams 500 , the at least two side beams 500 are spaced apart in the left-right direction, and the middle beam 400 is disposed between the at least two side beams 500 in the left-right direction.

[0072] The middle beam 400 and the side beam 500 are arranged between the battery pack and the front compartment in the up and down directions. In the process of transmitting force through the middle beam 400 and the side beam 500, the force transmission path can bypass the front compartment and the battery pack, reducing the possibility of damage to people in the front compartment and the batteries in the battery pack.

[0073] Specifically, the inclined surface 313 is higher at a side close to the front longitudinal beam 100 and lower at a side away from the front longitudinal beam 100 , so as to at least be able to transmit the force in the front-rear direction to the middle beam 400 and the side beam 500 .

[0074] In some embodiments, the inclined surface 313 extends in the left-right direction.

[0075] On the one hand, in the above embodiment, by providing the inclined surface 313, the front panel 300 can transfer part of the force to the middle beam 400 and the side beam 500 through the inclined surface 313 after being subjected to the force in the front and rear directions, so that the energy can be output to the rear of the frame through the middle beam 400 and the side beam 500, bypassing the passengers and the battery, thereby improving the overall rigidity of the vehicle body, reducing the possibility of the front panel 300 invading the front cabin due to failure, and further improving the safety performance of the frame.

[0076] On the other hand, the protruding portion forming the inclined surface 313 can also improve the rigidity of the front panel 300, further reducing the possibility of the front panel 300 failing and invading the front cabin, thereby further improving the safety performance of the vehicle frame.

[0077] In some embodiments, see Figure 1 and Figure 2 The frame also includes a rocker beam 600 and a front subframe 700. The rocker beam 600 is connected to the A-pillar 200. The front subframe 700 is connected to the front longitudinal beam 100. The front panel 300 also includes an anti-torsion portion 330. The anti-torsion portion 330 is connected to the reinforcement portion 320. The anti-torsion portion 330 is arranged between the main body portion 310 and the rocker beam 600, and is respectively connected to the main body portion 310 and the rocker beam 600. The front subframe 700 is connected to the side of the anti-torsion portion 330 away from the reinforcement portion 320. The anti-torsion portion 330, the main body portion 310 and the reinforcement portion 320 are an integrated structure.

[0078] Specifically, the front enclosure 300 includes two anti-torsion portions 330 , and the main body 310 is disposed between the two anti-torsion portions 330 along the left-right direction and respectively connects the two anti-torsion portions 330 .

[0079] In some embodiments, the A-pillar 200 is connected above the rocker beam 600 .

[0080] First, in the above embodiment, the front subframe 700 is connected to the side of the anti-torsion portion 330 away from the reinforcement portion 320, and the front subframe 700 is connected to the front longitudinal beam 100, and the front longitudinal beam 100 is connected to the reinforcement portion 320. The reinforcement portion 320 and the anti-torsion portion 330 are an integrated structure. That is, the front subframe 700, the front longitudinal beam 100 and the front enclosure 300 form a triangular structure with good rigidity, thereby improving the rigidity of the frame and thereby improving the safety performance of the frame.

[0081] Secondly, the integrated structure of the torsion-resistant portion 330, the main body 310, and the reinforcement portion 320 further enhances the rigidity of the front panel 300, thereby reducing the risk of the front panel 300 intruding into the front cabin during a collision due to poor rigidity, thereby improving the safety performance of the vehicle frame. Furthermore, the integrated front panel 300 reduces the total number of components, reducing the possibility of rigidity degradation due to connection instability, further enhancing the rigidity of the vehicle frame. Furthermore, reducing the number of components also reduces the weight of the front panel 300, thereby improving the performance of the vehicle frame.

[0082] Thirdly, the torsion-resistant portion 330 connecting the rocker beam 600 and the front subframe 700 can also transfer the force exerted on the front subframe 700 to the rear of the frame through the rocker beam 600, bypassing the passengers and the battery, thereby further improving the overall rigidity of the frame and enhancing the safety performance of the frame.

[0083] In some embodiments, see Figure 2 The vehicle frame further includes a side beam 500 , which is disposed on a side of the front enclosure 300 away from the front longitudinal beam 100 , and is connected to the anti-torsion portion 330 .

[0084] In the above embodiment, by connecting the side beam 500 to the side of the torsion-resistant portion 330 facing away from the front longitudinal beam 100, when the torsion-resistant portion 330 is subjected to the force of the front subframe 700, the force can be transmitted to the rear of the frame through the side beam 500, bypassing the passengers and the battery, so as to share the force received by the front of the frame, thereby improving the overall rigidity of the frame and enhancing the safety performance of the frame.

[0085] In some embodiments, the front enclosure 300 further includes a first connection portion 340 and a second connection portion 350. The first connection portion 340 is connected to the side of the reinforcement portion 320 close to the front longitudinal beam 100. The front longitudinal beam 100 is connected to the first connection portion 340, and the front longitudinal beam 100 is connected to the reinforcement portion 320. The second connection portion 350 is connected to the anti-torsion portion 330, the front subframe 700 is connected to the second connection portion 350, and the first connection portion 340 is connected to the second connection portion 350.

[0086] Specifically, the first connection portion 340 is used to connect to the front longitudinal beam 100 , and the second connection portion 350 is used to connect to the front subframe 700 .

[0087] In some embodiments, one side of the front longitudinal beam 100 in the left-right direction is affixed to and connected to the first connection portion 340 ; in some embodiments, one side of the front longitudinal beam 100 close to another front longitudinal beam 100 is affixed to and connected to the first connection portion 340 .

[0088] In some embodiments, the first connection portion 340 is connected to the body portion 310 .

[0089] In some embodiments, the vehicle frame includes two front longitudinal beams 100, each of which has an inner surface, and a portion of the first connecting portion 340 is bonded to and connected to the inner surface. The portion of the first connecting portion 340 bonded to the inner surface extends in the up-down direction and is respectively connected to the main body portion 310, the anti-torsion portion 330, and the second connecting portion 350, so that the portion of the first connecting portion 340 bonded to the inner surface can serve as a reinforcement rib of the front panel 300, thereby improving the rigidity of the front panel 300 in the up-down direction.

[0090] First, in the above embodiment, by providing a connection portion that connects the reinforcement portion 320 and the second connection portion 350 and is used to connect the front longitudinal beam 100, the first connection portion 340 is made more rigid in the up and down directions, thereby reducing the possibility of the rear end of the front longitudinal beam 100 tilting upward and invading the front cabin after a collision, thereby further improving the safety performance of the frame.

[0091] Secondly, in the above embodiment, the first connection portion 340 connecting the reinforcement portion 320 and the second connection portion 350 can serve as a reinforcement rib of the front panel 300 in the vertical direction, thereby improving the rigidity of the front panel 300 in the vertical direction and thus improving the safety performance of the frame.

[0092] Thirdly, the connection between the first connecting portion 340 and the second connecting portion 350 and the reinforcing portion 320 can also improve the rigidity of the second connecting portion 350, reduce the risk of failure of the second connecting portion 350, improve the connection reliability between the front subframe 700 and the front panel 300, and further improve the safety performance of the frame.

[0093] In some embodiments, see Figure 2 and Figure 5 The reinforcement portion 320 includes a first reinforcement sub-portion 322 and a second reinforcement sub-portion 323. The front longitudinal beam 100 is connected to the first reinforcement sub-portion 322. The first reinforcement sub-portion 322 is arranged between the A-pillars 200 and connects the A-pillars 200; the second reinforcement sub-portion 323 is connected to the first reinforcement sub-portion 322, and the front longitudinal beam 100 is connected to the second reinforcement sub-portion 323.

[0094] It is understandable that, since the first reinforcing sub-portion 322 is disposed between the A-pillars 200 , in order to ensure that the first reinforcing sub-portion 322 enhances the rigidity of the front enclosure 300 , the first reinforcing sub-portion 322 has a smaller size in the vertical direction.

[0095] In some embodiments, the second reinforcing sub-portion 323 is connected to the lower portion of the first reinforcing sub-portion 322 .

[0096] In some embodiments, the first reinforcing sub-section 322 and the second reinforcing sub-section 323 are both formed by the front enclosure 300 protruding toward the front longitudinal beam 100, and the groove 321 of the first reinforcing sub-section 322 and the groove 321 of the second reinforcing sub-section 323 are connected to enhance the rigidity of the reinforcing section 320 and reduce the possibility of deformation between the first reinforcing sub-section 322 and the second reinforcing sub-section 323.

[0097] In the above embodiment, the second reinforcement subsection 323, connected to the first reinforcement subsection 322, is provided to expand the connection area between the front longitudinal link and the reinforcement section 320. This allows the rear end of the front longitudinal member 100 to be fully connected to the reinforcement section 320, thereby enhancing the reinforcement section 320's ability to transmit force from the front longitudinal member 100 and improving the overall rigidity of the vehicle frame. Furthermore, the second reinforcement subsection 323 increases the vertical rigidity of the front panel 300, thereby improving the overall rigidity of the vehicle frame.

[0098] In some embodiments, see Figure 2 and Figure 5 The reinforcement portion 320 further includes a third reinforcement sub-portion 324, which is connected between the second reinforcement sub-portion 323 and the A-pillar 200, and respectively connects the second reinforcement sub-portion 323 and the A-pillar 200. Accordingly, the present application also provides a vehicle, including a frame as described in any one of the above embodiments.

[0099] In some embodiments, the first reinforcing sub-portion 322 and the third reinforcing sub-portion 324 are spaced apart from each other.

[0100] In some embodiments, see Figure 5 The front enclosure 300 includes a third reinforcing rib 380 , which connects the first reinforcing sub-portion 322 and the second reinforcing sub-portion 323 , and at least some of the plurality of third reinforcing ribs 380 connect the second reinforcing sub-portion 323 and the third reinforcing sub-portion 324 .

[0101] In some embodiments, the third reinforcing sub-section 324 is formed by the front enclosure 300 protruding toward the front longitudinal beam 100, and the groove 321 of the third reinforcing sub-section 324 is connected to the groove 321 of the second reinforcing sub-section 323 to enhance the rigidity of the reinforcing section 320 and reduce the possibility of deformation between the third reinforcing sub-section 324 and the second reinforcing sub-section 323.

[0102] In the above embodiment, a third reinforcing sub-section 324 is provided between the second reinforcing sub-section 323 and the A-pillar 200 so as to transmit the force of the second reinforcing sub-section 323 on the side away from the first reinforcing sub-section 322 to the A-pillar 200, thereby reducing the possibility of failure of the side of the second reinforcing sub-section 323 away from the first reinforcing sub-section 322, thereby improving the rigidity of the front panel 300, reducing the possibility of failure of the front panel 300 and intrusion into the front cabin due to the inability to output the force of the second reinforcing sub-section 323 on the side away from the first reinforcing sub-section 322 in a timely manner, and improving the safety performance of the vehicle frame.

[0103] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 A plurality of first reinforcing ribs 360 are provided on the side of the front enclosure 300 away from the front longitudinal beam 100 and the side close to the front longitudinal beam 100 . The first reinforcing ribs 360 extend in the left-right direction to enhance the rigidity of the front enclosure 300 in the left-right direction.

[0104] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 A plurality of second reinforcing ribs 370 are provided on the side of the front enclosure 300 away from the front longitudinal beam 100 and the side close to the front longitudinal beam 100 . The second reinforcing ribs 370 extend in the up-down direction to enhance the rigidity of the front enclosure 300 in the up-down direction.

[0105] In the above embodiment, the front panel 300 is an integrally formed part, which can effectively reduce the number of parts, improve the rigidity of the front panel 300 , reduce the amount of intrusion into the front cabin, improve the safety performance of the frame, and also allow the frame to be lighter.

[0106] In some embodiments, see Figure 4The front longitudinal beam 100 is connected to the front wall 300 by bolts. Specifically, a plurality of connecting columns 390 are provided on the side of the front wall 300 away from the front longitudinal beam 100, and the bolts are passed through the connecting columns 390, wherein each connecting column 390 is connected to at least one of the first reinforcing rib 360 and the second reinforcing rib 370 to reduce the possibility of the connecting column 390 being skewed after being subjected to force, thereby improving the connection stability of the front wall 300 and the front longitudinal beam 100.

[0107] In some embodiments, see Figure 4 and Figure 6 At least one of the multiple connecting columns 390 connected to the single front longitudinal beam 100 is connected to the third reinforcing rib 380, and at least one third reinforcing rib 380, at least one second reinforcing rib 370 and at least one first reinforcing rib 360 are connected to the connecting column 390 and extend radially.

[0108] In the above embodiment, the front longitudinal beam 100 and the front subframe 700 can absorb collision energy and are detachably connected to the front panel 300 for easy maintenance and replacement.

[0109] In the above embodiment, the integrally formed front enclosure 300 with good rigidity is located between the collision crumple zone formed by the front longitudinal beam 100 and the front subframe 700 and the rear safety zone to resist deformation, thereby minimizing the amount of entry into the front cabin to protect the safety of personnel and further improving the safety performance of the safety zone.

[0110] In some embodiments, see Figure 10 The main body portion 310 is located on a side of the reinforcement portion 320 away from the front longitudinal beam 100 , and the main body portion 310 includes a fourth reinforcement sub-portion 314 , both ends of which are connected to the A-pillar 200 .

[0111] It is understandable that the main body portion 310 is disposed on a side of the reinforcement portion 320 away from the front longitudinal beam 100 , that is, in the front-to-back direction, the main body portion 310 is further rearward than the reinforcement portion 320 .

[0112] In the above embodiment, the main body portion 310 arranged on the side of the reinforcement portion 320 away from the front longitudinal beam 100 can allow the main body portion 310 to move a certain distance backward, so as to extend the contact time between the components in front of the front panel 300 and the front panel 300 after a collision in the front-to-back direction, thereby reducing the impact of the components in front of the front panel 300 on the front panel 300 after the collision, making the structure of the frame more reasonable and improving the safety performance of the frame.

[0113] In some embodiments, the component in front of the front panel 300 may be the four-wheel drive motor 10 .

[0114] See also Figure 10 , the dotted line is the possible position of the four-wheel drive motor 10 after the collision occurs. Figure 10 In the figure, since the main body 310 is located on the side of the reinforcement part 320 away from the front longitudinal beam 100, the four-wheel drive motor 10 located at the dotted line does not contact the front wall 300, and it may even take a while before the four-wheel drive motor 10 contacts the front wall 300.

[0115] In some embodiments, see Figure 3 and Figure 5 The main body portion 310 also includes a first connecting sub-portion 315, which connects the reinforcement portion 320 and the fourth reinforcement sub-portion 314. The first connecting sub-portion 315 has an installation space 311 and a mounting hole 312. The first connecting sub-portion 315 protrudes toward the direction close to the front longitudinal beam 100 to form the installation space 311, and the mounting hole 312 is staggered with the fourth reinforcement sub-portion 314.

[0116] In some embodiments, see Figure 7 The fourth reinforcing sub-portion 314 is recessed forward and / or downward to form a recess, thereby forming a hollow beam structure. This improves the mechanical properties of the fourth reinforcing sub-portion 314, a portion of the integrated front dash 300. Furthermore, in some embodiments, at least one first reinforcing rib 360 can be connected to the fourth reinforcing sub-portion 314 to further cooperate with the recess walls and enclose the recess, thereby increasing the depth of the recess and further enhancing the mechanical energy absorption of the fourth reinforcing sub-portion 314.

[0117] In some embodiments, the fourth reinforcing sub-portion 314 is connected below the first connecting sub-portion 315 .

[0118] In some embodiments, both ends of the fourth reinforcement sub-portion 314 are respectively connected to the A-pillar 200 .

[0119] In some embodiments, both ends of the fourth reinforcement sub-portion 314 are respectively connected to the second reinforcement sub-portion 323 , and the fourth reinforcement sub-portion 314 is connected to the A-pillar 200 through the second reinforcement sub-portion 323 and the third reinforcement sub-portion 324 .

[0120] In some embodiments, the first connection portion 340 is connected to the fourth reinforcing sub-portion 314 . The fourth reinforcing sub-portion 314 can improve the mechanical properties of the first connection portion 340 and enhance the connection stability between the first connection portion 340 and the front longitudinal beam 100 .

[0121] It can be understood that, according to the foregoing, since the main body portion 310 is located on the side of the reinforcement portion 320 away from the front longitudinal beam 100, when the installation space 311 protrudes from the first connecting sub-portion 315 toward the direction close to the front longitudinal beam 100, in some embodiments, the installation space 311 can be located below the groove 321.

[0122] Specifically, the misalignment between the mounting hole 312 and the fourth reinforcing sub-portion 314 means that along the extending direction of the mounting hole 312 , the orthographic projection of the fourth reinforcing sub-portion 314 is separated from the orthographic projection of the hole wall of the mounting hole 312 .

[0123] On the one hand, in the above embodiment, by setting the first connecting sub-portion 315 connected to the reinforcement portion 320 to protrude toward the direction close to the front longitudinal beam 100, the installation space 311 can be located below the groove 321 and can be directly connected to the groove 321, so that the structure of the front panel 300 is more reasonable.

[0124] Second, in the above embodiments, please refer to Figure 7 Since the main body 310 is located behind the reinforcement portion 320, and the installation space 311 is formed by a portion protruding forward, that is, at least a portion of the installation space 311 is located further forward than the fourth reinforcement sub-portion 314, the installation hole 312 connected to the installation space 311 can also be located further forward than the fourth reinforcement sub-portion 314 and offset from the fourth reinforcement sub-portion 314. This allows the steering column 20 passing through the installation hole 312 to be located in front of the fourth reinforcement sub-portion 314, so that after a collision occurs, the fourth reinforcement sub-portion 314 with stronger mechanical properties can support the steering column 20 from the rear of the steering column 20, reducing the possibility of the steering column 20 damaging the front panel 300 and invading the front cabin, thereby improving the safety performance of the vehicle frame.

[0125] Thirdly, in the above embodiment, the fourth reinforcing sub-portion 314 can also play a role in transmitting force, that is, transmitting the force received by the front panel 300 in the left-right direction, so as to transmit the force to other directions of the frame through the A-pillar 200, thereby further improving the mechanical properties of the frame.

[0126] In some embodiments, see Figure 5 and Figure 10 The main body portion 310 further includes a fifth reinforcing sub-portion 316 , which protrudes in a direction away from the front longitudinal beam 100 , and both ends of the fifth reinforcing sub-portion 316 are connected to the anti-torsion portion 330 .

[0127] In some embodiments, the fifth reinforcing sub-portion 316 is connected to a side of the fourth reinforcing sub-portion 314 away from the first connecting sub-portion 315 .

[0128] First, in the above embodiment, the fifth reinforcement sub-portion 316 can be formed by making a portion of the body portion 310 protrude in a direction away from the front longitudinal beam 100 so as to improve the local mechanical properties of the integrated body portion 310 .

[0129] Secondly, in the above embodiment, the fifth reinforcing sub-portion 316 connected to the anti-torsion portion 330 can transmit the received force in the left-right direction toward the anti-torsion portion 330 and then to the A-pillar 200 and the rocker beam 600, so as to improve the overall mechanical properties of the vehicle frame.

[0130] In some embodiments, see Figure 1 、 Figure 2 and Figure 10 The vehicle frame further includes a middle beam 400 , which is located on a side of the fourth reinforcement sub-portion 314 away from the front longitudinal beam 100 and is connected to the fourth reinforcement sub-portion 314 .

[0131] First, in the above embodiment, the middle beam 400 connected to the fourth reinforcing sub-section 314 is provided to transfer the force applied to the front panel 300 to the rear, bypassing the personnel and the battery, thereby improving the performance of the vehicle frame and reducing the possibility of personal injury and battery damage after a collision.

[0132] Second, see Figure 10 In the above embodiment, when the components in front of the front panel 300 collide with the fourth reinforcing sub-portion 314, the middle beam 400 connected to the fourth reinforcing sub-portion 314 can support the fourth reinforcing sub-portion 314, thereby reducing the possibility of failure of the fourth reinforcing sub-portion 314 and improving the mechanical properties of the front panel 300.

[0133] In some embodiments, see Figure 1 and Figure 2 The frame also includes a side beam 500, which is connected to the side of the main body 310 away from the front longitudinal beam 100; wherein the frame has a preset plane 800, the extension direction of the side beam 500 is parallel to the preset plane 800, and the preset plane 800 passes through the second connecting portion 350.

[0134] Specifically, the preset plane 800 is a plane perpendicular to the left-right direction, and the side beam 500 extends in the front-back direction. Figure 9 When the vehicle collides, the second connecting portion 350 and the front subframe 700 will move along Figure 9 The second connecting portion 350 is twisted, and the rear end of the front subframe 700 may move from the bottom to the top of the front enclosure 300, that is, Figure 9 Clockwise direction in .

[0135] In some embodiments, see Figure 8 and Figure 9 A plurality of second reinforcing ribs 370 are connected to the side of the second connecting portion 350 close to the front longitudinal beam 100 to pull the second connecting portion 350 after a collision occurs, thereby reducing the possibility of the lower end of the second connecting portion 350 rotating toward the front enclosure 300.

[0136] In the above embodiment, by providing the side beam 500 and limiting the position of the side beam 500 , the front panel 300 can be supported from above the front panel 300 after the front subframe 700 contacts the front panel 300 , thereby reducing the possibility of the front subframe 700 breaking through the front panel 300 and injuring people.

[0137] In addition, the side member 500 connected to the side of the front wall 300 away from the front longitudinal beam 100 can also transmit the force applied to the front wall 300 to the rear, thereby improving the mechanical performance of the vehicle frame.

[0138] In some embodiments, the side beams 500 and the middle beam 400 are spaced apart.

[0139] In some embodiments, see Figure 3 、 Figure 9 and Figure 10 The main body 310 has an inclined surface 313 on a side facing away from the front longitudinal beam 100 , and the side beam 500 is connected to the inclined surface 313 .

[0140] In some embodiments, the lower end of the main body 310 is inclined in a direction away from the front longitudinal beam 100 , that is, the upper end of the main body 310 is located in front of the lower end to form an inclined surface 313 .

[0141] In some embodiments, the side beam 500 is in contact with and connected to the inclined surface 313 , so as to achieve a better force transmission effect between the front wall 300 and the side beam 500 .

[0142] In some embodiments, the middle beam 400 is also aligned with and connected to the inclined surface 313 .

[0143] In the above embodiment, the provision of the inclined surface 313 allows forces acting on the front panel 300 to be directly transmitted to the side rails 500 or the center rail 400 via the inclined surface 313, thereby improving force transmission and thereby enhancing the mechanical properties of the vehicle frame. Furthermore, the inclined surface 313 also reduces the shearing effect on the fasteners connecting the side rails 500 and the center rail 400 during force transmission, thereby improving the stability of the connections between the side rails 500 and the front panel 300, and between the center rail 400 and the front panel 300.

[0144] In the above embodiment, the door sill and the A-pillar 200 enable the force transmission path to bypass the front cabin and the battery pack, thereby protecting personnel and batteries.

[0145] In the above embodiment, the force transmission paths include at least the following three:

[0146] First transmission path: After the front longitudinal beam 100 is subjected to force, the force is transmitted to the A-pillar 200 and the rear of the vehicle body through the reinforcement 320;

[0147] The second transmission path: after the front longitudinal beam 100 is subjected to force, the force is transmitted to the A-pillar 200 and the rear of the vehicle body through the fourth reinforcement sub-portion 314;

[0148] In the third force transmission path, after the front subframe 700 is subjected to force, the force is transmitted to the rear of the frame through the fifth reinforcing sub-portion 316 , the anti-torsion portion 330 and the rocker beam 600 .

[0149] Correspondingly, the present application also provides a vehicle, comprising a frame as described in any one of the above embodiments.

[0150] In the above embodiment, due to the use of a frame with fewer parts and better rigidity, the vehicle has better safety performance, and after a collision occurs, people and batteries are not easily injured.

[0151] The above is a detailed introduction to a frame and a vehicle provided in the embodiments of the present application.
