[0044] With the continuous progress of society, cars have entered more families. But at the same time, traffic accidents also trouble everyone. In the relevant technology, the force transmission path of the front cabin longitudinal beam is relatively single, which means that when the vehicle collides, the front cabin longitudinal beam will transmit the force to the vehicle body in a relatively concentrated manner, and the force cannot be effectively dispersed. This will cause the vehicle body to be easily damaged in the structure, causing serious safety accidents.

[0045] Based on this, an embodiment of the first aspect of the present application provides a front engine compartment assembly, which aims to improve the problem of the relatively single force transmission path of the front engine compartment longitudinal beam, so as to reduce the probability of structural damage to the vehicle body when the vehicle collides.

[0046] like Figure 1 , Figure 2 as well as Figure 3As shown, the front cabin assembly in the embodiment of the present application includes a front cabin longitudinal beam 10, a front wall reinforcement beam 20 and a torsion box reinforcement plate 30. Specifically, a first protrusion 121 and a second protrusion 122 are provided on one side of the front cabin longitudinal beam 10, and the first protrusion 121 and the second protrusion 122 are both extended from one end of the front cabin longitudinal beam 10 to the other end, and the first protrusion 121 and the second protrusion 122 are arranged at intervals, the front wall reinforcement beam 20 is located behind the front cabin longitudinal beam 10, and the front wall reinforcement beam 20 is connected to the first protrusion 121, and the torsion box reinforcement plate 30 is located behind the front cabin longitudinal beam 10, and the torsion box reinforcement plate 30 is connected to the second protrusion 122.

[0047] Specifically, the first protrusion 121 and the second protrusion 122 are both raised structures formed on one side surface of the front cabin longitudinal beam 10. It can be understood that a recessed structure 123 is formed between the first protrusion 121 and the second protrusion 122. In addition, the front (or front) and rear (or rear) mentioned in this article are in 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.

[0048] In the front cabin assembly in the embodiment of the present application, a first protrusion 121 and a second protrusion 122 are formed on one side of the front cabin longitudinal beam 10, and the first protrusion 121 and the second protrusion 122 constitute the structural reinforcement part of the front cabin longitudinal beam 10, 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 20, so that the first protrusion 121 and the front wall reinforcement beam 20 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 30, so that the second protrusion 122 and the torsion box reinforcement plate 30 constitute another force transmission path. In this way, the problem that the force transmission path of the front cabin longitudinal beam 10 in the related art is relatively single can be improved. In this way, it is conducive to dispersing the force on the vehicle body, thereby reducing the probability of structural damage to the vehicle body when the vehicle collides.

[0049] Further, the front cabin longitudinal beam 10 may include a longitudinal beam inner plate 11 and a longitudinal beam outer plate 12 connected to each other, and the longitudinal beam outer plate 12 forms a first protrusion 121 and a second protrusion 122 on a side away from the longitudinal beam inner plate 11. Correspondingly, the front wall reinforcement beam 20 and the torsion box reinforcement plate 30 are both connected to the longitudinal beam outer plate 12. It can be understood that the first protrusion 121 and the second protrusion 122 are both protruding in a direction away from the longitudinal beam inner plate 11.

[0050] Specifically, the longitudinal beam inner plate 11 and the longitudinal beam outer plate 12 can be buckled together so that the longitudinal beam inner plate 11 and the longitudinal beam outer plate 12 can jointly define an internal cavity, and a reinforcement member, such as a reinforcement plate, can be arranged in the internal cavity, thereby improving the structural strength of the front cabin longitudinal beam 10.

[0051] In some of the embodiments, Figure 1 , Figure 4 as well as Figure 5 As shown, a third protrusion 31 and a fourth protrusion 32 are provided on one side of the torsion box reinforcement plate 30, and the third protrusion 31 and the fourth protrusion 32 are extended from one end of the torsion box reinforcement plate 30 close to the front cabin longitudinal beam 10 to the end away from the front cabin longitudinal beam 10, and the third protrusion 31 and the fourth protrusion 32 are both connected with the second protrusion 122.

[0052] The third protrusion 31 and the fourth protrusion 32 are bulge structures formed on one side surface of the torsion box reinforcement plate 30. The third protrusion 31 and the fourth protrusion 32 constitute the structural reinforcement part of the torsion box reinforcement plate 30, and also constitute the main force transmission structure of the torsion box reinforcement plate 30. In other words, by providing the third protrusion 31 and the fourth protrusion 32, two force transmission paths are further constructed on the torsion box reinforcement plate 30, one of which is composed of the second protrusion 122 and the third protrusion 31, and the other is composed of the second protrusion 122 and the fourth protrusion 32. In this way, when the vehicle collides, the force on the vehicle body can be further dispersed, thereby further reducing the probability of structural damage to the vehicle body.

[0053] Furthermore, if Figure 1 As shown, the front engine compartment assembly further includes an A-pillar lower section inner plate 40 and a sill beam 50, the torsion box reinforcement plate 30 is connected to the A-pillar lower section inner plate 40, the torsion box reinforcement plate 30 is also connected to the sill beam 50, the third protrusion 31 is connected to the A-pillar lower section inner plate 40, and the fourth protrusion 32 is connected to the sill beam 50. In this way, the force can be transmitted to the A-pillar lower section inner plate 40 through the force transmission path formed by the second protrusion 122 and the third protrusion 31, and the force can be transmitted to the sill beam 50 through the force transmission path formed by the second protrusion 122 and the fourth protrusion 32. In other words, the force from the front engine compartment longitudinal beam 10 can be transmitted to different A-pillar lower section inner plates 40 and sill beams 50 through the above two force transmission paths, so as to achieve the purpose of dispersing the force on the vehicle body.

[0054] Furthermore, the dash reinforcement beam 20 is connected to the A-pillar lower section inner plate 40. With such a configuration, the force can be transmitted to the A-pillar lower section inner plate 40 through the force transmission path formed by the first protrusion 121 and the dash reinforcement beam 20. It should be understood that although the force transmission path formed by the first protrusion 121 and the dash reinforcement beam 20 and the force transmission path formed by the second protrusion 122 and the third protrusion 31 are both to transmit force to the A-pillar lower section inner plate 40, the force points on the A-pillar lower section inner plate 40 are different, so the purpose of dispersing the force can also be achieved.

[0055] In some of the embodiments, Figure 6 As shown, the front cabin assembly also includes a torsion box 60, which is located at the bottom of the torsion box reinforcement plate 30 and connected to the torsion box reinforcement plate 30. The torsion box 60 is also connected to the front cabin longitudinal beam 10. The front cabin assembly also includes a floor side beam 70 and a middle channel side beam 80. The floor side beam 70, the middle channel side beam 80 and the threshold beam 50 are all connected to the end of the torsion box 60 away from the front cabin longitudinal beam 10. The floor side beam 70, the middle channel side beam 80 and the threshold beam 50 are parallel. In this way, the force from the front cabin longitudinal beam 10 can be transmitted to the floor side beam 70 and the middle channel side beam 80 in addition to the threshold beam 50. The threshold beam 50, the floor side beam 70 and the middle channel side beam 80 respectively constitute three force transmission paths of the front cabin floor part. In this way, the force on the vehicle body can be further dispersed, thereby further reducing the probability of structural damage to the vehicle body when the vehicle collides.

[0056] Furthermore, the projection of the floor side beam 70 in the front-to-rear direction of the vehicle at least partially overlaps with the projection of the front cabin longitudinal beam 10 in the front-to-rear direction of the vehicle. In this way, the front cabin longitudinal beam 10 and the floor side beam 70 can more effectively transmit force in the front-to-rear direction of the vehicle, thereby improving the force transmission effect.

[0057] In some of the embodiments, Figure 7 , Figure 8 As shown, the front engine compartment assembly further includes a front cowl upper plate 90, a front cowl lower plate 100, a front cowl reinforcement plate 110 and a torsion box 60. The front cowl lower plate 100 is located below the front cowl upper plate 90. The front cowl upper plate 90 and the front cowl lower plate 100 are both connected to the front cowl reinforcement beam 20. The front cowl reinforcement plate 110 is connected to the front cowl upper plate 90 and the front cowl lower plate 100. The torsion box 60 is connected to the torsion box reinforcement plate 30. The torsion box 60, the torsion box reinforcement plate 30, the front cowl lower plate 100 and the front cowl reinforcement plate 110 jointly define a cavity structure. The front cowl reinforcement beam 20 and the torsion box reinforcement plate 30 are also connected to the middle of the front cowl reinforcement plate 110 to separate the cavity structure into two chambers.

[0058] The cavity structure defined by the torsion box 60, the torsion box reinforcement plate 30, the front lower plate 100 and the front reinforcement plate 110 has the function of absorbing collision energy when the vehicle collides. When the vehicle collides more seriously, the cavity structure will collapse and deform under the impact of the collision, thereby absorbing the collision energy. In this embodiment, the front reinforcement beam 20 and the torsion box reinforcement plate 30 are also connected to the middle of the front reinforcement plate 110 to divide the cavity structure into two chambers. After repeated tests and verifications, it is found that dividing the cavity structure with a larger volume into two chambers with relatively smaller volumes can improve the ability to absorb collision energy.

[0059] Furthermore, if Figure 7 , Figure 8 As shown, a boss structure 111 is formed in the middle of the front enclosure reinforcement plate 110, and the boss structure 111 protrudes in the direction of the torsion box reinforcement plate 30. The front enclosure reinforcement beam 20 is provided with a first flange 21, and the torsion box reinforcement plate 30 is provided with a second flange 33. The first flange 21 and the second flange 33 are both connected to the boss structure 111.

[0060] A boss structure 111 is formed in the middle of the dash reinforcement plate 110, and the boss structure 111 can enhance the reinforcement effect of the dash reinforcement plate 110. In addition, the dash reinforcement beam 20 is provided with a first flange 21, and the torsion box reinforcement plate 30 is provided with a second flange 33, and the first flange 21 and the second flange 33 are both connected to the boss structure 111, thereby achieving the purpose of dividing the cavity structure into two relatively small chambers, thereby improving the ability to absorb collision energy.

[0061] 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.

[0062] In the vehicle of the embodiment of the present application, in the front cabin assembly, a first protrusion 121 and a second protrusion 122 are formed on one side of the front cabin longitudinal beam 10, and the first protrusion 121 and the second protrusion 122 constitute the structural reinforcement part of the front cabin longitudinal beam 10, 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 20, so that the first protrusion 121 and the front wall reinforcement beam 20 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 30, so that the second protrusion 122 and the torsion box reinforcement plate 30 constitute another force transmission path. In this way, the problem that the force transmission path of the front cabin longitudinal beam 10 in the related art is relatively single can be improved. In this way, it is conducive to dispersing the force on the vehicle body, thereby reducing the probability of structural damage to the vehicle body when the vehicle collides.

[0063] 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. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
