[0037] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.
[0038] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.
[0039] Refer to Figure 1 、 Figure 2 and Figure 7 This application discloses an anti-collision beam assembly 10, including an anti-collision beam 1 and two top blocks 2. The anti-collision beam 1 extends along the width direction of the vehicle 300. The anti-collision beam 1 is connected to the front ends of two lower longitudinal beams 60 of the engine compartment, and the anti-collision beam 1 extends outwards from the lower longitudinal beams 60 of the engine compartment. The part of the anti-collision beam 1 extending out of the lower longitudinal beams 60 of the engine compartment is the outer overhanging part 11; that is, the left outer overhanging part 11 is located on the left side of the left lower longitudinal beam 60 of the engine compartment, and the right outer overhanging part 11 is located on the right side of the right lower longitudinal beam 60 of the engine compartment.
[0040] The two top blocks 2 are respectively connected to the two outer overhanging parts 11. For example, the top blocks 2 can be connected to the left and right ends of the anti-collision beam 1, that is, the top blocks 2 are connected to the outermost sides of the corresponding outer overhanging parts 11. For example, the top block 2 and the corresponding outer overhanging part 11 can be connected by welding, the top block 2 and the corresponding outer overhanging part 11 can be connected by a fastener 4, and the top block 2 and the corresponding outer overhanging part 11 can be integrally formed parts.
[0041] The top block 2 is spaced from the corresponding lower longitudinal beam 60 of the engine compartment. The top block 2 includes a connection part 21 and a stop part 22. The connection part 21 is connected to the outer overhanging part 11, and the stop part 22 is close to the corresponding lower longitudinal beam 60 of the engine compartment. The stop part 22 is adapted to stop against the corresponding lower longitudinal beam 60 of the engine compartment when the outer overhanging part 11 is stressed and bent.
[0042] When the vehicle 300 undergoes an offset collision, the overhanging portion 11 is stressed and can rotate around the connection point between the anti-collision beam 1 and the corresponding lower longitudinal beam 60 of the engine compartment, so that the top block 2 abuts against the lower longitudinal beam 60 of the engine compartment in the width direction. The top block 2 can transmit the collision force to the upper longitudinal beam of the engine compartment. Since the top block 2 is spaced from the corresponding upper longitudinal beam of the engine compartment in the width direction, the top block 2 can convert the collision force in the length direction received by the anti-collision beam 1 into a force in the width direction, and disperse the collision force to the engine compartment frame assembly 100 along the width direction through the corresponding lower longitudinal beam 60 of the engine compartment, causing the engine compartment frame assembly 100 to collapse in the width direction, reducing the collapse amount of the engine compartment frame assembly 100 in the length direction, making the collision force transmitted to the A-pillar through the engine compartment frame assembly 100 smaller, reducing the deformation amount of the A-pillar, reducing the deformation amount of the occupant compartment, improving the offset collision performance of the vehicle 300, and improving the safety performance of the vehicle 300.
[0043] The top block 2 is spaced from the corresponding lower longitudinal beam 60 of the engine compartment. When the vehicle 300 undergoes an offset collision and the collision force is small, this can enable the anti-collision beam 1 to bear the collision force in the length direction, enabling the anti-collision beam 1 to absorb more collision energy, reducing the force transmitted from the top block 2 to the lower longitudinal beam 60 of the engine compartment or avoiding the force in the width direction on the lower longitudinal beam 60 of the engine compartment, reducing the collapse amount of the engine compartment frame assembly 100 caused by the top block 2 squeezing the corresponding lower longitudinal beam 60 of the engine compartment, reducing the repair cost of the vehicle 300 after collision, and improving the overall performance of the vehicle 300.
[0044] According to the anti-collision beam assembly 10 provided by the embodiment of the present disclosure, by providing a top block 2 adapted to abut against the lower longitudinal beam 60 of the engine compartment on the overhanging portion 11 of the anti-collision beam 1 and spacing the top block 2 from the lower longitudinal beam 60 of the engine compartment, when the vehicle 300 undergoes an offset collision, the overhanging portion 11 rotates around the connection point between the anti-collision beam 1 and the corresponding lower longitudinal beam 60 of the engine compartment, and the top block 2 abuts against the lower longitudinal beam 60 of the engine compartment in the width direction, which can convert the collision force in the length direction into a force in the width direction, disperse the collision force to the engine compartment frame assembly 100, making the collision force transmitted to the A-pillar through the engine compartment frame assembly 100 smaller, reducing the deformation amount of the A-pillar, reducing the deformation amount of the occupant compartment, improving the offset collision performance of the vehicle 300, and improving the safety performance of the vehicle 300; moreover, when the vehicle 300 undergoes an offset collision and the collision force is small, spacing the top block 2 from the lower longitudinal beam 60 of the engine compartment can reduce the collapse amount of the engine compartment frame assembly 100, reduce the repair cost of the vehicle 300 after collision, and improve the overall performance of the vehicle 300.
[0045] Refer to Figure 2 According to some embodiments provided by the present application, the anti-collision beam assembly 10 further includes: an abutting and cooperating member 3, the abutting and cooperating member 3 is fixedly connected to the lower longitudinal beam 60 of the engine compartment, and the abutting and cooperating member 3 is located between the corresponding abutting portion 22 and the corresponding lower longitudinal beam 60 of the engine compartment.
[0046] By providing the anti-contact fitting 3, the structural strength of the lower longitudinal beam 60 of the engine compartment can be improved. When the top block 2 presses against the corresponding lower longitudinal beam 60 of the engine compartment, the deformation amount of the corresponding lower longitudinal beam 60 can be reduced, so that the corresponding lower longitudinal beam 60 can reliably transfer the collision force transmitted by the top block 2 to the other side, enabling the collision force to be reliably dispersed to the engine compartment frame assembly 100, allowing the engine compartment frame assembly 100 to absorb more collision energy, thereby reducing the collision amount transmitted to the A-pillar through the engine compartment frame assembly 100, reducing the deformation amount of the A-pillar, reducing the deformation amount of the passenger compartment, improving the offset collision performance of the vehicle 300, and enhancing the safety performance of the vehicle 300.
[0047] Referring to Figure 2 , according to some embodiments provided by the present application, the anti-contact fitting 3 is opposite to the subframe mounting point 12 on the lower longitudinal beam 60 of the engine compartment in the width direction of the vehicle 300. The subframe mounting upright is connected to the lower longitudinal beam 60 of the engine compartment, and the connection point between the subframe mounting upright and the lower longitudinal beam 60 of the engine compartment is the subframe mounting point 12. At the position of the subframe mounting point 12, the front cross beam of the engine compartment is connected to the lower longitudinal beam 60 of the engine compartment, and the connection point between the front cross beam of the engine compartment and the lower longitudinal beam 60 of the engine compartment is opposite to the subframe mounting point 12 in the width direction, and the structural strength of the lower longitudinal beam 60 of the engine compartment is relatively high at the subframe mounting point 12.
[0048] When the top block 2 presses against the corresponding lower longitudinal beam 60 of the engine compartment, the deformation amount of the corresponding lower longitudinal beam 60 can be reduced, so that the corresponding lower longitudinal beam 60 can transfer the collision force transmitted by the top block 2 to the other side through the subframe mounting upright and the front cross beam of the engine compartment, enabling the collision force to be reliably dispersed to the engine compartment frame assembly 100 through the subframe mounting upright and the front cross beam of the engine compartment, allowing the engine compartment frame assembly 100 to absorb more collision energy, thereby reducing the collision amount transmitted to the A-pillar through the engine compartment frame assembly 100, reducing the deformation amount of the A-pillar, reducing the deformation amount of the passenger compartment, improving the offset collision performance of the vehicle 300, and enhancing the safety performance of the vehicle 300.
[0049] Referring to Figure 2 , Figures 6 - 8 , according to some embodiments provided by the present application, a stop groove 24 is provided at one end of the stop portion 22 close to the anti-contact fitting 3, and a part of the anti-contact fitting 3 is engageable with the stop groove 24. When the top block 2 moves towards the anti-contact fitting 3, the top block 2 can be engaged with the anti-contact fitting 3 through the stop groove 24, preventing the top block 2 from sliding relative to the anti-contact fitting 3 and preventing the top block 2 from sliding relative to the lower longitudinal beam 60 of the engine compartment, enabling the top block 2 to reliably press against a preset point on the lower longitudinal beam 60 of the engine compartment in the width direction, so that the collision force received by the anti-collision beam 1 can be reliably transmitted to the other side of the engine compartment frame assembly 100 through the lower longitudinal beam 60 of the engine compartment, improving the reliability of the anti-collision beam assembly 10.
[0050] For example, when the abutting fitting 3 is opposite to the subframe mounting point 12 on the lower longitudinal beam 60 of the engine compartment in the width direction of the vehicle 300, the top block 2 can reliably press the position of the subframe mounting point 12 on the lower longitudinal beam 60 of the engine compartment through the abutting fitting 3, so that the lower longitudinal beam 60 of the engine compartment can reliably transmit the collision force transmitted by the top block 2 to the other side through the subframe mounting upright column and the front cross beam of the engine compartment, and the collision force can be reliably dispersed to the engine compartment frame assembly 100 through the subframe mounting upright column and the front cross beam of the engine compartment, thereby improving the reliability of the anti-collision beam assembly 10 and the reliability of the engine compartment frame assembly 100.
[0051] Refer to Figures 3 - 6 According to some embodiments provided by the present application, the anti-collision beam 1 has a buffer cavity 13, the connecting portion 21 is disposed through the buffer cavity 13, and the connecting portion 21 is connected to the corresponding overhanging portion 11 through a fastener 4, and the fastener 4 extends along the length direction of the vehicle 300. For example, the fastener 4 can be a bolt, and the top block 2 is provided with a fastening hole 25, and the fastener 4 is disposed through the fastening hole 25. By connecting the top block 2 to the corresponding overhanging portion 11 through the fastener 4, that is, the anti-collision beam 1 and the top block 2 are separately provided, which can make the structures of the anti-collision beam 1 and the top block 2 relatively simple, facilitate production and manufacturing, reduce production costs, and improve production efficiency.
[0052] By setting the fastener 4 to extend along the length direction of the vehicle 300, when the vehicle 300 collides, this can prevent the top block 2 from generating a shearing force on the fastener 4 and causing the fastener 4 to break, so that the fastener 4 can reliably fix the top block 2 relative to the anti-collision beam 1, prevent the anti-collision beam 1 from falling off from the corresponding overhanging portion 11, and improve the reliability of the anti-collision beam assembly 10.
[0053] Refer to Figures 3 - 6 According to some embodiments provided by the present application, the connecting portion 21 has a clearance fit with the side wall of the buffer cavity 13 in the height direction of the vehicle 300; this facilitates inserting the connecting portion 21 into the buffer cavity 13, improves the assembly efficiency of the anti-collision beam assembly 10, improves the production efficiency of the anti-collision beam assembly 10, and reduces production costs.
[0054] Refer to Figures 3 - 6 According to some embodiments provided by the present application, the connecting portion 21 abuts against the side wall of the buffer cavity 13 in the length direction of the vehicle 300. When a collision occurs, the side wall of the buffer cavity 13 in the length direction can play a certain limiting role on the connecting portion 21, so that the connecting portion 21 is reliably fixed relative to the overhanging portion 11, and the top block 2 is reliably fixed relative to the overhanging portion 11, so that the top block 2 can reliably press a preset point of the lower longitudinal beam 60 of the engine compartment, and the reliability of the anti-collision beam assembly 10 is improved.
[0055] Refer to Figures 3 - 6, according to some embodiments provided by the present application, the anti-collision beam assembly 10 further includes: a reinforcing plate 5, the reinforcing plate 5 is disposed on a side of the outer overhanging portion 11 away from the abutting portion 22, and the reinforcing plate 5 is connected to the outer overhanging portion 11 through a fastener 4. This can improve the structural strength of the outer overhanging portion 11, so that when the outer overhanging portion 11 is deformed by force, the outer overhanging portion 11 can drive the top block 2 to rotate reliably around the connection point between the corresponding lower longitudinal beam 60 of the engine compartment and the anti-collision beam 1, so that the top block 2 can reliably abut against a preset point on the lower longitudinal beam 60 of the engine compartment, thereby improving the reliability of the anti-collision beam assembly 10 and the reliability of the engine compartment skeleton assembly 100.
[0056] Referring to Figures 3 - 6 , according to some embodiments provided by the present application, a convex bump 51 is formed on the reinforcing plate 5, and the convex bump 51 protrudes from the fastener 4 in a direction away from the abutting portion 22. When the vehicle 300 collides, the convex bump 51 can preferentially abut against the collision object 70 relative to the fastener 4, that is, the convex bump 51 bears the force preferentially relative to the fastener 4, so that the force on the fastener 4 is smaller, preventing a large collision force from acting on the fastener 4 and causing the connection between the top block 2 and the outer overhanging portion 11 to fail, so that the top block 2 can be reliably fixed relative to the corresponding outer overhanging portion 11, thereby improving the reliability of the anti-collision beam assembly 10 and the reliability of the engine compartment skeleton assembly 100.
[0057] For example, referring to Figures 3 - 6 , according to some specific embodiments provided by the present application, the convex bump 51 is annularly arranged, and the annular convex bump 51 defines an avoidance groove 52, and a part of the fastener 4 protruding from the outer overhanging portion 11 in a direction away from the abutting portion 22 is disposed in the avoidance groove 52. By providing the annular convex bump 51 to protect the fastener 4, the fastener 4 can be protected more effectively, thereby further improving the reliability of the anti-collision beam assembly 10 and the reliability of the engine compartment skeleton assembly 100.
[0058] Referring to Figures 2 - 8 , according to some embodiments provided by the present application, the top block 2 has a plurality of weight reduction holes 23, the weight reduction holes 23 penetrate through the top block 2 along the height direction of the vehicle 300, and the thickness of the side wall of the weight reduction hole 23 is not less than 5 mm and not more than 15 mm. For example, the thickness of the side wall of the weight reduction hole 23 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm. Specifically, the thickness of the side wall of the weight reduction hole 23 can be set to different thicknesses according to the force condition.
[0059] By providing a plurality of weight-reducing holes 23 and setting the thickness of the side walls of the weight-reducing holes 23 to be not less than 5 mm and not more than 15 mm, the weight of the top block 2 can be effectively reduced, the cost of the top block 2 can be reduced, the weight of the anti-collision beam assembly 10 can be reduced, and the weight of the whole vehicle can be reduced. At the same time, the top block 2 can have sufficient structural strength, so that the top block 2 can reliably transmit the collision force to the lower longitudinal beam 60 of the engine compartment, ensuring the reliability of the collision force transmission.
[0060] Referring to Figure 1 and Figure 2 , the present application also discloses an engine compartment frame assembly 100, including: two lower longitudinal beams 60 of the engine compartment and an anti-collision beam assembly 10. The lower longitudinal beams 60 of the engine compartment extend along the length direction of the vehicle 300, and the two lower longitudinal beams 60 of the engine compartment are spaced apart along the width direction of the vehicle 300. The anti-collision beam assembly 10 is the anti-collision beam assembly 10 disclosed in the above embodiments of the present application. For example, the engine compartment frame assembly 100 may include a front cross beam of the engine compartment and a subframe mounting column. The connection point of the front cross beam of the engine compartment and the lower longitudinal beam 60 of the engine compartment is opposite to the subframe mounting point 12 in the width direction. The subframe mounting column is connected to the lower longitudinal beam 60 of the engine compartment, and the connection point of the subframe mounting column and the lower longitudinal beam 60 of the engine compartment is the subframe mounting point 12.
