[0044] With the continuous progress of society, vehicles have entered more families. At the same time, people have also put forward higher requirements for vehicle safety. In the front frame structure of the vehicle, the front cabin longitudinal beam plays an important supporting and protective role. When the front of the vehicle collides, the front cabin longitudinal beam needs to play a more reliable protective role and should not cause serious collapse and deformation.
[0045] The reliability of the front cabin longitudinal beam in the related technology is not ideal, and it is easy to produce serious deformation during vehicle collision, so there is a safety hazard.
[0046] Based on this, an embodiment of the first aspect of the present application provides a front cabin assembly, which aims to improve the problem that the front cabin longitudinal beam is prone to serious deformation during a vehicle collision, so as to improve safety.
[0047] like Figure 1 , Figure 2 as well as Figure 3 As shown, the front cabin assembly in the embodiment of the present application includes a front cabin longitudinal beam 10, an inner plate reinforcement plate 20 and a reinforcement column 30. The front cabin longitudinal beam 10 includes an inner longitudinal beam plate 11 and an outer longitudinal beam plate 12 connected to each other, the inner longitudinal beam plate 11 and the outer longitudinal beam plate 12 define an internal cavity, the inner plate reinforcement plate 20 is located in the internal cavity, the inner plate reinforcement plate 20 is connected to the inner longitudinal beam plate 11, and the inner plate reinforcement plate 20 is provided with a boss 24, which protrudes in a direction away from the inner longitudinal beam plate 11. The reinforcement column 30 is located in the internal cavity, the end of the reinforcement column 30 is connected to the inner longitudinal beam plate 11, and the reinforcement column 30 is also connected to the boss 24.
[0048] Specifically, the front engine compartment longitudinal beam 10 is a structure formed by buckling a longitudinal beam inner plate 11 and a longitudinal beam outer plate 12, so that the longitudinal beam inner plate 11 and the longitudinal beam outer plate 12 together enclose an internal cavity. This front engine compartment longitudinal beam 10 is also a structure adopted by most models in the related art.
[0049] The inner plate reinforcement plate 20 is disposed in the internal cavity, and a boss 24 is provided on the inner plate reinforcement plate 20, and the boss 24 is a raised structure formed on the inner plate reinforcement plate 20. The inner plate reinforcement plate 20 can be formed by a sheet metal processing process, and illustratively, the boss 24 on the inner plate reinforcement plate 20 can be formed by sheet metal stamping.
[0050] In addition, the front (or forward) and rear (or rearward) mentioned in this article are with reference to the vehicle, that is, the direction pointed by the front of the vehicle is the front, and the direction pointed by the rear of the vehicle is the rear.
[0051] In the front engine room assembly in the embodiment of the present application, an inner plate reinforcement plate 20 connected to the longitudinal beam inner plate 11 is arranged in the internal cavity of the front engine room longitudinal beam 10, and a boss 24 is arranged on the inner plate reinforcement plate 20. The arrangement of the boss 24 makes the inner plate reinforcement plate 20 itself have a good structural strength, thereby making the front engine room longitudinal beam 10 provided with the inner plate reinforcement plate 20 have a better structural strength. In addition, the front engine room longitudinal beam 10 is also provided with a reinforcement column 30, which connects the longitudinal beam inner plate 11 and the boss 24 of the inner plate reinforcement plate 20. The arrangement of the reinforcement column 30 can further improve the structural reinforcement effect of the inner plate reinforcement plate 20 on the front engine room longitudinal beam 10, so that the structural strength of the front engine room longitudinal beam 10 can be further improved. As a result, the ability of the front engine room longitudinal beam 10 to resist collision can be improved, so that the front engine room longitudinal beam 10 will not produce more serious deformation when the vehicle collides, thereby improving the safety of the vehicle.
[0052] In some of the embodiments, Figure 4 , Figure 5 as well as Figure 6 As shown, the longitudinal beam inner plate 11 includes a side plate 111 and an upper bottom plate 112 and a lower bottom plate 113 respectively connected to the upper and lower sides of the side plate 111. The inner plate reinforcement plate 20 includes a reinforcement plate body 21, an upper flange 22 and a lower flange 23, the upper flange 22 is connected to the upper side of the reinforcement plate body 21, the lower flange 23 is connected to the lower side of the reinforcement plate body 21, the reinforcement plate body 21 is abutted against the side plate 111, a boss 24 is formed on the reinforcement plate body 21, the upper flange 22 is connected to the upper bottom plate 112, and the lower flange 23 is connected to the lower bottom plate 113. The end of the reinforcement column 30 is connected to at least one of the upper bottom plate 112 and the lower bottom plate 113.
[0053] In this embodiment, the inner plate reinforcement plate 20 includes a reinforcement plate body 21, an upper flange 22 and a lower flange 23, wherein the upper flange 22 is connected to the upper bottom plate 112 of the longitudinal beam inner plate 11, and the lower flange 23 is connected to the lower bottom plate 113 of the longitudinal beam inner plate 11. Thus, the inner plate reinforcement plate 20 and the longitudinal beam inner plate 11 are stacked, thereby significantly improving the structural strength of the longitudinal beam inner plate 11. In addition, the end of the reinforcement column 30 is connected to at least one of the upper bottom plate 112 and the lower bottom plate 113, and the reinforcement column 30 is also connected to the boss 24, thereby realizing the connection between the reinforcement column 30 and the inner plate reinforcement plate 20 and the inner plate reinforcement plate 20.
[0054] In some of the embodiments, Figure 3 , Figure 6As shown, there are multiple bosses 24, which are arranged at intervals along the length direction of the front cabin longitudinal beam 10, and there are multiple reinforcing columns 30, which are arranged one by one with multiple reinforcing columns 30 and multiple bosses 24, and each reinforcing column 30 is connected to a corresponding boss 24. On the one hand, the number of bosses 24 and reinforcing columns 30 is multiple, which is conducive to further improving the structural strength of the front cabin longitudinal beam 10. On the other hand, multiple bosses 24 are arranged at intervals along the length direction of the front cabin longitudinal beam 10, which is conducive to improving the uniformity of the distribution of the structural strength of the front cabin longitudinal beam 10 in its own length direction.
[0055] In some of the embodiments, Figure 5 , Figure 6 As shown, the reinforcement plate body 21 is also formed with a protruding structure 211, which protrudes in the direction away from the longitudinal beam inner plate 11. The protruding structure 211 extends from the front end to the rear end of the inner plate reinforcement plate 20 and connects two adjacent bosses 24; wherein the protruding height of the protruding structure 211 is smaller than the protruding height of the boss 24.
[0056] The raised structure 211 is a raised structure formed on the reinforcement plate body 21. By forming the raised structure 211 extending from the front end to the rear end on the inner plate reinforcement plate 20, the ability of the inner plate reinforcement plate 20 to resist impacts in the front and rear directions can be enhanced. As a result, the reinforcing effect of the inner plate reinforcement plate 20 on the structural strength of the front cabin longitudinal beam 10 can be improved. In addition, since the boss 24 is also used to connect with the reinforcement column 30, the raised height of the boss 24 can be greater than the raised height of the raised structure 211, so that the operation can be convenient when the boss 24 is connected to the reinforcement column 30.
[0057] In some of the embodiments, Figure 5 As shown, a through hole 2111 is provided on the protruding structure 211 , and the through hole 2111 is an oblong hole extending along the front-to-rear direction of the inner plate reinforcing plate 20 .
[0058] Although the front cabin longitudinal beam 10 needs to have good structural strength, it also needs to have reasonable crush-buffering performance. When the vehicle collides at high speed, the front cabin longitudinal beam 10 needs to produce crush deformation, thereby absorbing the collision energy by crush deformation, so as to reduce the deformation risk of the cockpit and ensure the safety of personnel. In this embodiment, a through hole 2111 is provided on the protruding structure 211, and the through hole 2111 is an oblong hole extending along the front and rear direction of the inner plate reinforcement plate 20. The provision of the through hole 2111 can make the inner plate reinforcement plate 20 have a certain crush-buffering capacity, so that in the case of a high-speed collision, the inner plate reinforcement plate 20 can be more easily crushed and deformed, thereby absorbing the collision energy and playing a role in protecting the cockpit.
[0059] In some of the embodiments, Figure 3 , Figure 7 as well as Figure 8 As shown, the front engine compartment assembly further includes a torque box 40, a longitudinal beam subframe rear mounting plate 50 and a first connecting plate 60. The torque box 40 is connected to the rear end of the front engine compartment longitudinal beam 10. The longitudinal beam subframe rear mounting plate 50 is located on the upper side of the torque box 40 and fits the torque box 40. The longitudinal beam subframe rear mounting plate 50 is connected to the torque box 40. The first connecting plate 60 is located in the internal cavity and is connected to the longitudinal beam inner plate 11, the inner plate reinforcement plate 20 and the longitudinal beam subframe rear mounting plate 50.
[0060] The longitudinal beam subframe rear mounting plate 50 is used to connect the subframe and the front cabin longitudinal beam 10. Specifically, there are multiple connection locations between the subframe and the front cabin longitudinal beam 10, one of which is located at the rear end of the front cabin longitudinal beam 10. At this connection location, the subframe is connected to the longitudinal beam subframe rear mounting plate 50 through a connector, and the connector is inserted into the torsion box 40. Thus, the subframe and the front cabin longitudinal beam 10 are connected together through the longitudinal beam subframe rear mounting plate 50, the connector, the torsion box 40, etc.
[0061] In this embodiment, one end of the first connecting plate 60 is connected to the longitudinal beam inner plate 11 and the inner plate reinforcement plate 20, and the other end is connected to the longitudinal beam subframe rear mounting plate 50. The inner plate reinforcement plate 20, the first connecting plate 60 and the longitudinal beam subframe rear mounting plate 50 constitute a force transmission path, so that the inner plate reinforcement plate 20 can better withstand the force, thereby improving the structural reinforcement effect of the inner plate reinforcement plate 20 on the front cabin longitudinal beam 10.
[0062] Furthermore, if Figure 3 , Figure 7 as well as Figure 8 As shown, the first connecting plate 60 includes a connecting plate body 61, a first flange 62 and a second flange 63, the second flange 63 and the first flange 62 are located on opposite sides of the connecting plate body 61, the connecting plate body 61 is against the lower bottom plate 113, the first flange 62 is connected to the side plate 111, and the second flange 63 is connected to the longitudinal beam outer plate 12. In this way, the first connecting plate 60 is connected not only to the longitudinal beam inner plate 11, but also to the longitudinal beam outer plate 12, so that the connection stability between the first connecting plate 60 and the front cabin longitudinal beam 10 can be improved, so that the first connecting plate 60 can stably play a force transmission role.
[0063] Furthermore, if Figure 3 , Figure 7As shown, the front cabin assembly also includes a second connecting plate 70, which is connected to the reinforcing plate body 21, the first flange 62, and the second flange 63. Since the reinforcing plate body 21 of the inner plate reinforcing plate 20 abuts against the side plate 111 of the longitudinal beam inner plate 11, and the connecting plate body 61 of the first connecting plate 60 abuts against the lower bottom plate 113 of the longitudinal beam inner plate 11, the connection strength between the first connecting plate 60 and the inner plate reinforcing plate 20 is relatively weak. Therefore, in this embodiment, a second connecting plate 70 is also provided, which is connected to the reinforcing plate body 21, the first flange 62, and the second flange 63 of the first connecting plate 60, thereby improving the connection strength between the first connecting plate 60 and the inner plate reinforcing plate 20 through the second connecting plate 70, so that the inner plate reinforcing plate 20 and the first connecting plate 60 can better transmit force.
[0064] In some of the embodiments, Figure 2 , Fig. 9 As shown, the front cabin assembly further includes a front wall reinforcement beam 80 and a torsion box reinforcement plate 90, both of which are located behind the front cabin longitudinal beam 10. A first protrusion 121 and a second protrusion 122 are formed on the side of the longitudinal beam outer plate 12 away from the longitudinal beam inner plate 11, and the first protrusion 121 and the second protrusion 122 both extend from one end to the other end of the front cabin longitudinal beam 10, and the first protrusion 121 and the second protrusion 122 are arranged at intervals. The front wall reinforcement beam 80 is connected to the first protrusion 121, and the torsion box reinforcement plate 90 is connected to the second protrusion 122.
[0065] The first protrusion 121 and the second protrusion 122 are both bulge structures formed on one side surface of the longitudinal beam outer plate 12. It can be understood that a recessed structure 123 is formed between the first protrusion 121 and the second protrusion 122. The first protrusion 121 and the second protrusion 122 constitute the structural reinforcement part of the longitudinal beam outer plate 12, and also constitute the main force transmission structure of the front cabin longitudinal beam 10. The first protrusion 121 extends from one end of the front cabin longitudinal beam 10 to the other end and is connected to the front wall reinforcement beam 80, so that the first protrusion 121 and the front wall reinforcement beam 80 constitute a force transmission path; the second protrusion 122 extends from one end of the front cabin longitudinal beam 10 to the other end and is connected to the torsion box reinforcement plate 90, so that the second protrusion 122 and the torsion box reinforcement plate 90 constitute another force transmission path. That is to say, a plurality of force transmission paths are constructed through the above structure, so that when the vehicle collides, the front cabin longitudinal beam 10 can be prevented from transmitting force to the vehicle body in a relatively concentrated manner, thereby reducing the probability of structural damage to the vehicle body when the vehicle collides.
[0066] An embodiment of a second aspect of the present application provides a vehicle, which includes a front cabin assembly according to any embodiment of the first aspect.
[0067] In the vehicle of the embodiment of the present application, in the front cabin assembly, an inner plate reinforcement plate 20 connected to the longitudinal beam inner plate 11 is provided in the internal cavity of the front cabin longitudinal beam 10, and a boss 24 is provided on the inner plate reinforcement plate 20. The setting of the boss 24 makes the inner plate reinforcement plate 20 itself have a good structural strength, thereby making the front cabin longitudinal beam 10 provided with the inner plate reinforcement plate 20 have a better structural strength. In addition, the front cabin longitudinal beam 10 is also provided with a reinforcement column 30, which connects the longitudinal beam inner plate 11 and the boss 24 of the inner plate reinforcement plate 20. The setting of the reinforcement column 30 can further improve the structural reinforcement effect of the inner plate reinforcement plate 20 on the front cabin longitudinal beam 10, so that the structural strength of the front cabin longitudinal beam 10 can be further improved. As a result, the ability of the front cabin longitudinal beam 10 to resist collision can be improved, so that the front cabin longitudinal beam 10 will not produce more serious deformation when the vehicle collides, thereby improving the safety of the vehicle.
[0068] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
