[0028] The frame is an important part of the car. It bears the role of load-bearing and collision prevention. When the vehicle collides, it can reduce the degree of injury to the occupants. Especially when the vehicle collides from the side, the driver and passengers are more vulnerable to injury. How to improve the collision safety performance of the vehicle is a problem.

[0029] In order to solve the related technical problems, the present application provides a vehicle frame 1, which includes a vehicle door sill 20, a B-pillar reinforcement 10, and a seat mounting cross beam 30. The vehicle door sill 20 is extended along a first direction X, and the vehicle door sill 20 forms a first energy absorption cavity 60 extending along the first direction X; the B-pillar reinforcement 10 is extended along a second direction Z, and the B-pillar reinforcement 10 is respectively connected to the vehicle door sill 20 and the B-pillar of the vehicle, and the B-pillar reinforcement 10 is provided with a second energy absorption cavity 70 extending along the second direction Z; the seat mounting cross beam 30 is connected to the vehicle door sill 20, and the seat mounting cross beam 30 is extended along a third direction Y, and the seat mounting cross beam 30 and the vehicle floor 50 form a third energy absorption cavity 80 extending along the third direction Y, wherein the first direction X, the second direction Z and the third direction Y are perpendicular to each other.

[0030] The first direction X is the front-to-back direction extending from the front to the rear of the vehicle, the second direction Z is the up-down direction extending from the roof to the chassis of the vehicle, and the third direction Y is the left-right direction extending along the doors on both sides of the vehicle. The first energy absorbing cavity 60 is disposed inside the vehicle threshold 20, and is not only extended along the first direction X, but also disposed inside the vehicle threshold 20 along the second direction Z. The first energy absorbing cavity 60 disposed on the vehicle threshold 20 can increase the deformation of the vehicle threshold 20 when a collision occurs, thereby increasing the collision energy absorbed by the vehicle threshold 20.

[0031] When the vehicle collides sideways, since the B-pillar reinforcement 10 and the B-pillar are located at the outermost part of the vehicle, the second energy absorption cavity 70 first generates deformation to absorb and unload the collision force, and then successively generates deformation to absorb and unload the collision force through the first energy absorption cavity 60 and the third energy absorption cavity 80. Through the setting of the three-stage energy absorption cavity, the collision force is unloaded step by step, reducing the intrusion amount of the B-pillar reinforcement 10, the B-pillar and the vehicle door sill 20, thereby reducing the injuries suffered by the vehicle driver and passengers, and effectively improving the vehicle collision safety performance.

[0032] The vehicle door sill 20 includes a door sill outer frame and a separator 210. The door sill outer frame is used to form a first energy absorbing cavity 60. The separator 210 is located in the first energy absorbing cavity 60. The separator 210 is connected to the inner side wall of the door sill outer frame to divide the first energy absorbing cavity 60 into a plurality of energy absorbing sub-cavities 610. The door sill outer frame as a whole forms the first energy absorbing cavity 60. The hollow first energy absorbing cavity 60 and the energy absorbing sub-cavities 610 can be dented inwards and deformed when a vehicle collides, thereby absorbing energy. The separator 210 is connected to the inner side wall of the door sill outer frame so that the energy absorbing sub-cavity 610 contacts the inner side wall of the door sill outer frame, thereby ensuring that the collision force is quickly transmitted to the plurality of energy absorbing sub-cavities 610.

[0033] The partition 210 includes a transverse plate 211 and a longitudinal plate 212. The transverse plate 211 is connected to the two inner side walls of the outer frame of the door sill in the third direction Y, and the longitudinal plate 212 is connected to the two inner side walls of the outer frame of the door sill in the second direction Z. The longitudinal plate 212 and the transverse plate 211 are arranged to intersect. The transverse plate 211 divides the first energy absorption cavity 60 into a plurality of energy absorption sub-cavities 610 in the third direction Y, and the longitudinal plate 212 divides the first energy absorption cavity 60 into a plurality of energy absorption sub-cavities 610 in the second direction Y, and the edges of the energy absorption sub-cavities 610 are arranged close to the inner side walls of the inner and outer frames of the door sill, so that the collision force is easily transmitted to the plurality of energy absorption sub-cavities 610. The plurality of energy absorption sub-cavities 610 absorb energy together, thereby improving the uniformity of deformation of the vehicle door sill 20 and avoiding partial tearing due to excessive collision deformation.

[0034] Among them, the number of transverse plates 211 is two, and the two transverse plates 211 are arranged at intervals in the second direction Z, and the two transverse plates 211 are arranged to intersect with the longitudinal plates 212 respectively. The transverse plates 211 and the longitudinal plates 212 are arranged to intersect so that a plurality of energy-absorbing sub-cavities 610 are formed inside the vehicle threshold 20 along the third direction Y and the second direction Z, so that the vehicle threshold 20 can uniformly absorb the collision energy in the third direction Y and the second direction Z, and avoid excessive local collision deformation. In this embodiment, the number of transverse plates 211 is two, so that the plurality of energy-absorbing sub-cavities 610 form a seven-square structure as a whole. The number of transverse plates 211 can also be other values, such as 3, depending on the actual situation. The more the number of transverse plates 211, the more energy-absorbing sub-cavities 610 are formed in the second direction Z. Similarly, the number of longitudinal plates 212 can also be other values, which will not be repeated here.

[0035] The partition 210 further includes a partition plate 213, which is spaced apart from the transverse plate 211 in the second direction Z, and is connected to the two inner side walls of the outer frame of the door sill in the third direction Y, and is spaced apart from the longitudinal plate 212. The partition plate 213 is used to form the seventh energy absorbing sub-cavity 610 at the bottom in the second direction Z. The seventh energy absorbing sub-cavity 610 is located near the bottom of the door sill, where the width of the door sill in the third direction Y is smaller than the width of the upper part of the door sill. Because most of the collision force during a side collision is borne by the upper part of the door sill and the B-pillar, the size of the bottom of the door sill where the seventh energy absorbing sub-cavity 610 is located is set slightly smaller, which can save vehicle assembly space.

[0036] Among them, the B-pillar reinforcement 10 includes a B-pillar reinforcement plate 110 and a B-pillar inner plate 120, the B-pillar reinforcement plate and the B-pillar inner plate 120 cooperate to form a second energy absorption cavity 70, the B-pillar reinforcement plate 110 is connected to the outer side wall of the vehicle threshold 20 in the third direction Y, and the B-pillar inner plate 120 is connected to the outer side wall of the vehicle threshold 20 in the second direction Z.

[0037] The lower part of the B-pillar is the key area that bears the collision force when a side collision occurs, so a B-pillar reinforcement plate 110 and a B-pillar inner plate 120 are arranged in the second direction Z. The B-pillar reinforcement plate 110 and the B-pillar inner plate 120 are laser welded to form a second energy absorption cavity 70 to improve the collision resistance here. The B-pillar reinforcement plate 110 extends to the vicinity of the middle of the vehicle threshold 20 in the second direction Z, further improving the collision resistance of the vehicle threshold 20. The B-pillar reinforcement plate 110 is made of soft drive material and connected to the vehicle threshold 20 using the FDS method.

[0038] The frame 1 further includes a crossbeam connecting plate 40, through which the seat mounting crossbeam 30 is fixedly connected to the vehicle threshold 20. The crossbeam connecting plate 40 is in a Z shape, and is connected to the vehicle threshold 20 and the seat mounting crossbeam 30 through two planes in an FDS manner, thereby increasing stability. At the same time, when the vehicle is hit sideways, the collision force is transmitted to the vehicle threshold 20, and then first transmitted from the vehicle threshold 20 to the crossbeam connecting plate 40, and finally transmitted to the seat mounting crossbeam 30, so that the crossbeam connecting plate 40 can also play a buffering role.

[0039] The crossbeam connecting plate 40 includes a first plate body 410, a second plate body 420 and a third plate body 430. The second plate body 420 is bent and connected to the first plate body 410 and the third plate body 430 respectively. The extension directions of the first plate body 410 and the third plate body 430 are opposite. The first plate body 410 and the second plate body 420 are respectively connected to the vehicle door sill 20.

[0040] The second plate body 420 is vertically connected to the first plate body 410 and the third plate body 430 respectively. Since the cross-beam connecting plate 40 has multiple plates, it is connected to the vehicle door sill 20 and the seat mounting cross-beam 30 through multiple planes, which increases the connection area and thus enhances the connection stability. When the vehicle has a side collision, the collision force can be transmitted through multiple plates, thereby reducing the local collision force and improving the buffering capacity.

[0041] The seat mounting cross beam 30 includes a top plate 310, two side plates 320 and two bottom plates 330 extending along the third direction Y. The two side plates 320 are spaced apart in the first direction X. One side plate 320 is respectively connected to one side edge of the top plate 310 and one bottom plate 330, and the other side plate 320 is respectively connected to the other side edge of the top plate 310 and the other bottom plate 330. The top plate 310 is connected to the first plate body 410, the two side plates 320 are respectively connected to the second plate body 420, and the two bottom plates 330 are respectively connected to the third plate body 430.

[0042] The top plate 310, two side plates 320, two bottom plates 330 and the vehicle floor 50 of the seat mounting cross beam 30 form a third energy absorbing chamber 80, which can further absorb the collision force and reduce the damage to the driver and passengers. The seat mounting cross beam 30 is connected to the cross beam connecting plate 40 through multiple planes, which increases the stability of the connection. At the same time, reinforcing ribs are arranged on the seat mounting cross beam 30. The two bottom plates 330 are connected to the third plate body 430 and are connected to the vehicle floor plate 330 at the same time.

[0043] In summary, the vehicle frame 1 provided by the present application includes a first energy absorption cavity 60 disposed along a first direction X on the vehicle door sill 20, a second energy absorption cavity 70 disposed along a second direction Z on the B-pillar reinforcement 10, and a third energy absorption cavity 80 disposed along a third direction Y. When a side collision occurs to the vehicle, the collision force is first absorbed and unloaded by the second energy absorption cavity 70, and then absorbed and unloaded by the first energy absorption cavity 60 and the third energy absorption cavity 80 in sequence. By disposing the three-stage energy absorption cavity, the collision force is unloaded step by step, thereby reducing the damage to the vehicle driver and passengers, and effectively improving the collision safety performance of the vehicle.

[0044] To solve the related technical problems, the present application also provides a vehicle, which includes the frame 1 as described above. The vehicle can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle.
