[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The impact beam assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0037] Reference Figure 1-Figure 6 According to the first aspect of the embodiment of the present invention, the anti-collision beam assembly 10 is applied to a vehicle, and the anti-collision beam assembly 10 includes a first anti-collision beam 1, a second anti-collision beam 2 and a force transmission connector 3. The first anti-collision beam 1 extends along the width direction of the vehicle, and the first anti-collision beam 1 is connected to the front end of the cabin longitudinal beam 50 of the vehicle; for example, the vehicle may also include a floor frame, the floor frame is connected to the rear end of the cabin longitudinal beam 50, and the floor frame is used to support the vehicle's seat.

[0038] The second anti-collision beam 2 extends along the width direction of the vehicle, and the second anti-collision beam 2 is connected to the front end of the subframe 60 of the vehicle; for example, the front end of the subframe 60 can be connected to the bottom of the cabin longitudinal beam 50, and the rear end of the subframe 60 can be connected to the front of the floor frame.

[0039] The force transmission connector 3 extends along the height direction of the vehicle, and the force transmission connector 3 is connected between the first anti-collision beam 1 and the second anti-collision beam 2. For example, the force transmission connector 3 can be sandwiched between the first anti-collision beam 1 and the second anti-collision beam 2, and the force transmission connector 3 can also overlap with a part of the first anti-collision beam 1 or a part of the second anti-collision beam 2 in the height direction of the vehicle; specifically, when the force transmission connector 3 overlaps with a part of the first anti-collision beam 1 in the height direction of the vehicle, the force transmission connector 3 can be superimposed on the front end of the first anti-collision beam 1, and the force transmission connector 3 can be superimposed on the rear end of the first anti-collision beam 1; when the force transmission connector 3 overlaps with a part of the second anti-collision beam 2 in the height direction of the vehicle, the force transmission connector 3 can also be superimposed on the front end of the second anti-collision beam 2, and the force transmission connector 3 can be superimposed on the rear end of the second anti-collision beam 2.

[0040] When the vehicle collides and the first anti-collision beam 1 collides with the obstacle first, the anti-collision beam assembly 10 can transmit the collision force to the cabin longitudinal beam 50 through the first collision beam, and at the same time transmit the collision force to the subframe 60 through the force transmission connector 3 and the second collision beam, and then the cabin longitudinal beam 50 and the subframe 60 transmit the collision force to the rear of the vehicle, so that the anti-collision beam assembly 10 has multiple force transmission paths, which effectively disperse the collision force of the vehicle, so that each force transmission path can bear a smaller collision force, thereby reducing the deformation of the cabin longitudinal beam 50 and the deformation of the subframe 60, so that the deformation of the cabin frame is smaller, the reliability of the cabin frame is improved, the amount of collapse of the cabin toward the cab is reduced, and the safety performance of the vehicle is improved.

[0041] When the vehicle collides and the second anti-collision beam 2 collides with the obstacle first, the anti-collision beam assembly 10 can transmit the collision force to the subframe 60 through the second collision beam, and at the same time transmit the collision force to the cabin longitudinal beam 50 through the force transmission connector 3 and the first collision beam, and then the cabin longitudinal beam 50 and the subframe 60 transmit the collision force to the rear of the vehicle, so that the anti-collision beam assembly 10 has multiple force transmission paths, which effectively disperse the collision force of the vehicle, so that each force transmission path can bear a smaller collision force, thereby reducing the deformation of the cabin longitudinal beam 50 and the deformation of the subframe 60, so that the deformation of the cabin frame is smaller, the reliability of the cabin frame is improved, the amount of collapse of the cabin toward the cab is reduced, and the safety performance of the vehicle is improved.

[0042] When the vehicle collides, the collision point is located between the first anti-collision beam 1 and the second anti-collision beam 2, and the force transmission connector 3 can first contact the obstacle, so that the force transmission connector 3 can transmit the collision force to the first anti-collision beam 1 and the second anti-collision beam 2, and then the force transmitted to the first anti-collision beam 1 can be transmitted to the rear of the vehicle through the cabin longitudinal beam 50, and the force transmitted to the second anti-collision beam 2 can be transmitted to the rear of the vehicle through the subframe 60, so that the anti-collision beam assembly 10 has multiple force transmission paths, which effectively disperse the collision force of the vehicle, so that each force transmission path can bear a smaller collision force, thereby reducing the deformation of the cabin longitudinal beam 50, reducing the deformation of the subframe 60, making the deformation of the cabin frame smaller, improving the reliability of the cabin frame, reducing the amount of collapse of the cabin toward the cab, and improving the safety performance of the vehicle.

[0043] When the vehicle collides, the collision point is located between the first anti-collision beam 1 and the second anti-collision beam 2, and the force transmission connection and the first anti-collision beam 1 and the second anti-collision beam 2 are in contact with the obstacle at the same time. In this way, the contact area between the anti-collision beam assembly 10 and the obstacle can be larger, and the collision force of the vehicle can be effectively dispersed, so that the first anti-collision beam 1, the second anti-collision beam 2 and the force transmission connection can all bear less collision force, thereby making the force transmitted from the first anti-collision beam 1 to the cabin longitudinal beam 50 smaller, and the force transmitted from the second anti-collision beam 2 to the subframe 60 smaller, reducing the deformation of the cabin longitudinal beam 50, reducing the deformation of the subframe 60, and making the deformation of the cabin frame smaller, thereby improving the reliability of the cabin frame, reducing the amount of collapse of the cabin toward the cab, and improving the safety performance of the vehicle.

[0044] According to the anti-collision beam assembly 10 of the present invention, by setting a force transmission connecting member 3 to connect the first anti-collision beam 1 and the second anti-collision beam 2, the anti-collision beam assembly 10 can have multiple force transmission paths, so that each force transmission path can bear a smaller collision force, reduce the deformation of the cabin longitudinal beam 50, reduce the deformation of the subframe 60, make the deformation of the cabin frame smaller, improve the reliability of the cabin frame, reduce the amount of collapse of the cabin toward the cab, improve the anti-collision performance of the anti-collision beam assembly 10, and improve the safety of the vehicle.

[0045] Reference Figure 1-Figure 6 According to some embodiments of the present invention, the force transmission connector 3 includes a first connecting section 31, a second connecting section 32 and a force transmission section 33, the force transmission section 33 extends along the height direction of the vehicle, the first connecting section 31 and the second connecting section 32 are respectively connected to the two ends of the force transmission section 33, the first connecting section 31 is connected to the side surface of the first anti-collision beam 1 away from the cabin longitudinal beam 50, and the second connecting section 32 is connected to the second anti-collision beam 2.

[0046] The first connecting section 31 is connected to the side surface of the first anti-collision beam 1 facing away from the cabin longitudinal beam 50, that is, the first connecting section 31 overlaps with a portion of the first anti-collision beam 1 in the height direction of the vehicle, and the first connecting section 31 is superimposed on the front end of the first anti-collision beam 1, that is, the force transmission connecting member 3 overlaps with a portion of the first anti-collision beam 1 in the height direction of the vehicle, and the force transmission connecting member 3 is superimposed on the front end of the first anti-collision beam 1.

[0047] When the front end of the vehicle is hit, the first connecting section 31 can collapse and deform toward the first anti-collision beam 1 after being subjected to force, so that the first connecting section 31 can reliably transfer the collision force to the first anti-collision beam 1, and then transfer it to the cabin longitudinal beam 50 by the first anti-collision beam 1, and finally reliably transfer the collision force to the rear part of the vehicle body, so that the collision force can be more reliably dispersed and absorbed in the vehicle body frame, thereby reducing the degree of deformation of the vehicle after the collision and improving the safety performance of the vehicle.

[0048] Reference Figure 1-Figure 6 According to some embodiments of the present invention, the force transmission connector 3 has a cavity structure. In this way, the structural strength of the force transmission connector 3 can be improved, so that the force transmission connector 3 can reliably transmit the force received by the first anti-collision beam 1 to the second anti-collision beam 2, and the force transmission connector 3 can reliably transmit the force received by the second anti-collision beam 2 to the first anti-collision beam 1, thereby improving the reliability of the anti-collision beam assembly 10. At the same time, when the force transmission connector 3 is subjected to a large force, a cavity structure is provided, so that the force transmission connector 3 has a certain deformation space, so that the force transmission connector 3 can absorb a part of the collision energy, so that the collision force transmitted to the first anti-collision beam 1 through the force transmission connector 3 is smaller, and the collision force transmitted to the second anti-collision beam 2 through the force transmission connector 3 is smaller, thereby improving the collision performance of the anti-collision beam assembly 10.

[0049] Reference Figure 1-Figure 6 According to some embodiments of the present invention, the force transmission connector 3 is formed by bending a sheet metal part, and the force transmission connector 3 has a cavity structure that opens away from the first anti-collision beam 1. For example, there may be multiple cavity structures, and the multiple cavity structures are arranged at intervals along the width direction of the vehicle. The force transmission connector 3 is connected to the first anti-collision beam 1 through a first fastener 41, and a part of the first fastener 41 is inserted into the cavity structure. For example, the first fastener 41 may be a bolt, or a rivet.

[0050] The cavity structure is set to be open in the direction away from the first anti-collision beam 1, so that the side wall of the force transmission connecting member 3 opposite to the opening of the cavity structure can be closely attached to the first anti-collision beam 1. When the force transmission connecting member 3 and the first anti-collision beam 1 are connected by the first fastener 41, the amplitude of the shaking of the force transmission connecting member 3 relative to the first anti-collision beam 1 is reduced, so that the first fastener 41 can reliably connect and fix the force transmission connecting member 3 and the first anti-collision beam 1, thereby improving the reliability of the anti-collision beam assembly 10.

[0051] Moreover, part of the first fastener 41 is inserted into the cavity structure, which can prevent the first fastener from protruding into the cavity structure, reduce the risk of interference between the first fastener 41 and the vehicle body shell, and at the same time, avoid obstacles from colliding with the first fastener 41 first, reduce the risk of failure of the first fastener 41 during a vehicle collision, and reduce the risk of the force transmission connector 3 falling off the first anti-collision component, so that the force transmission connector 3 can reliably transmit force between the first anti-collision beam 1 and the second anti-collision beam 2, thereby improving the reliability of the anti-collision beam assembly 10.

[0052] Reference Figure 1-Figure 6 According to some embodiments of the present invention, the first anti-collision beam 1 includes: a first beam body 11 and a first energy absorption box 12, the first beam body 11 extends along the width direction of the vehicle, the first energy absorption box 12 is connected to the first beam body 11, and there are two first energy absorption boxes 12 spaced apart along the width direction of the vehicle, each first energy absorption box 12 is connected to the corresponding cabin longitudinal beam 50 at an end away from the first beam body 11, and each first energy absorption box 12 has a cavity structure.

[0053] The first connecting section 31 is connected to a side surface of the first beam body 11 facing away from the cabin longitudinal beam 50 , that is, the first connecting section 31 overlaps with a portion of the first beam body 11 in the length direction of the vehicle, and the first connecting section 31 is superimposed on the front end of the first beam body 11 .

[0054] By providing a first energy absorption box 12 with a cavity structure and arranging the first energy absorption box 12 between the first beam body 11 and the cabin longitudinal beam 50, when a vehicle collides, the collision force can be first transmitted to the first beam body 11, then transmitted from the first beam body 11 to the first energy absorption box 12, and then transmitted from the first energy absorption box 12 to the cabin longitudinal beam 50.

[0055] When the collision force is transmitted to the first energy absorption box 12, the first energy absorption box 12 is deformed by the force and can absorb a part of the collision energy, so that the collision force transmitted to the cabin longitudinal beam 50 through the first energy absorption box 12 is smaller, thereby reducing the deformation degree of the cabin longitudinal beam 50, improving the reliability of the cabin longitudinal beam 50, and improving the collision performance of the anti-collision beam assembly 10.

[0056] Reference Figure 1-Figure 6 According to some embodiments of the present invention, the second anti-collision beam 2 includes: a second beam body 21 and a second energy absorbing box 22, the second beam body 21 extends along the width direction of the vehicle, the second energy absorbing box 22 is connected to the second beam body 21, and there are two second energy absorbing boxes 22 spaced apart along the width direction of the vehicle, each second energy absorbing box 22 is connected to the subframe 60 at an end away from the second beam body 21, and each second energy absorbing box 22 has a cavity structure.

[0057] The second connecting section 32 extends along the length direction of the vehicle, and the second connecting section 32 is connected to a side surface of the second energy absorbing box 22 in the height direction of the vehicle close to the first anti-collision beam 1. For example, the second connecting section 32 can be connected to the second energy absorbing box 22 through a second fastener 42, and specifically, the second fastener 42 can be a bolt, or a rivet.

[0058] When the first anti-collision beam 1 collides, the first anti-collision beam 1 can transfer the collision force to the second energy absorption box 22 through the force transmission connector 3, and then the second energy absorption box 22 transfers the collision force to the subframe 60, and then the subframe 60 transfers the collision force to the rear of the vehicle.

[0059] When the second anti-collision beam 2 collides, the second beam body 21 collides with the obstacle first, and the second beam body 21 can transfer the collision force to the second energy absorption box 22, and then the second energy absorption box 22 transfers the collision force to the subframe 60 and the second connecting section 32 respectively. The collision force transmitted to the second connecting section 32 can be transmitted to the cabin longitudinal beam 50 via the force transmission section 33, the first connecting section 31, and the first anti-collision beam 1, and then the cabin longitudinal beam 50 transfers the collision force to the rear of the vehicle.

[0060] By connecting the two connecting sections to the side surface of the second energy absorption box 22 close to the first anti-collision beam 1 in the height direction of the vehicle, mutual force transmission between the second anti-collision beam 2 and the first anti-collision beam 1 can be achieved. At the same time, it is not necessary to set a connection point on the second beam body 21, so that the smaller second beam body 21 can still meet the structural strength requirements of the second beam body 21, and the second beam body 21 can be set smaller, thereby reducing the weight of the entire vehicle.

[0061] Reference Figure 1-Figure 6 According to some embodiments of the present invention, there are multiple force transmission connectors 3, and the multiple force transmission connectors 3 are arranged at intervals along the width direction of the vehicle, and two adjacent force transmission connectors 3, the first anti-collision beam 1 and the second anti-collision beam 2 jointly define an air inlet 43. In this way, air can enter the engine room through the air inlet 43, so that the outside air can reliably participate in the heat exchange of the engine room, so that the outside air can reliably participate in the fresh air replacement of the cab, so that the outside air can reliably participate in the combustion of the engine, so that each component in the vehicle can work reliably, and the reliability of the vehicle is guaranteed.

The subframe 60 is connected to the bottom of the cabin longitudinal beam 50, for example, the front end of the subframe 60 can be connected to the bottom of the cabin longitudinal beam 50, and the rear end of the subframe 60 can be connected to the front of the floor frame. The anti-collision beam assembly 10 is the anti-collision beam assembly 10 according to the first embodiment of the present invention, wherein the first anti-collision beam 1 is connected to the front end of the cabin longitudinal beam 50, and the second anti-collision beam 2 is connected to the front end of the subframe 60.

[0063] According to the cabin frame assembly 100 of the present invention, through the above-mentioned anti-collision beam assembly 10, the cabin frame assembly 100 can have multiple force transmission paths, so that each force transmission path can bear a smaller collision force, so that the deformation of the cabin frame is smaller, the reliability of the cabin frame assembly 100 is improved, the amount of collapse of the cabin toward the cab is reduced, the anti-collision performance of the anti-collision beam assembly 10 is improved, and the safety of the vehicle is improved.

[0064] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the cabin frame assembly 100 further includes: a wheel house upper side beam 70 and a front enclosure assembly 80, the front enclosure assembly 80 is connected to the rear of the cabin longitudinal beam 50 and is located above the cabin longitudinal beam 50, the wheel house upper side beam 70 extends along the length direction of the vehicle, and one end of the wheel house upper side beam 70 is connected to the upper part of the front enclosure assembly 80, and the other end is connected to the cabin longitudinal beam 50, and the connection point between the wheel house upper side beam 70 and the cabin longitudinal beam 50 is opposite to the connection point between the subframe 60 and the cabin longitudinal beam 50 in the height direction of the vehicle. For example, the two ends of the front enclosure assembly 80 in the vehicle width direction can be respectively connected to the corresponding A-pillars, and part of the wheel house upper side beam 70 can also be connected to the A-pillar.

[0065] In this way, the structural strength of the area where the cabin longitudinal beam 50 and the subframe 60 are connected can be higher, and the degree of stress deformation in the area where the cabin longitudinal beam 50 and the subframe 60 are connected can be reduced, so that the subframe 60 and the cabin longitudinal beam 50 can reliably transmit forces to each other, and the collision force can be reliably transmitted to the rear of the vehicle through the cabin longitudinal beam 50, thereby improving the reliability of the cabin frame assembly 100 and the reliability of the vehicle.
