[0033] Reference below Figure 1-Figure 3 Describe the front structure 10 of the vehicle according to an embodiment of the utility model.
[0034] like Figure 1-Figure 3 As shown, the front structure 10 of the vehicle according to the embodiment of the utility model comprises: a front wall lower cross beam 1, a front floor cross beam 2 and a center channel reinforcement beam 3.
[0035] Specifically, refer to Figure 1 and Figure 2The front enclosure lower cross beam 1 is located at the front side of the front floor cross beam 2 and is spaced apart from the front floor cross beam 2. The front floor cross beam 2 is one and extends in the left-right direction. One end of the front floor cross beam 2 is connected to the left door sill beam of the vehicle, and the other end of the front floor cross beam 2 is connected to the right door sill beam of the vehicle. The middle channel reinforcement beam 3 is arranged between the front enclosure lower cross beam 1 and the front floor cross beam 2. The front end of the middle channel reinforcement beam 3 is connected to the front enclosure lower cross beam 1, and the rear end of the middle channel reinforcement beam 3 is connected to the front floor cross beam 2.
[0036] It should be noted that, when the front of the vehicle 100 is hit, the center channel reinforcement beam 3 is used to transfer the collision force received by the front panel lower cross beam 1 to the front floor cross beam 2. At the same time, the center channel reinforcement beam 3, the front panel lower cross beam 1 and the front floor cross beam 2 jointly bear the collision force, thereby reducing the overall deformation of the front structure 10 of the vehicle and protecting the safety of the occupants.
[0037] At the same time, the center channel reinforcement beam 3 is arranged between the front panel lower cross beam 1 and the front floor cross beam 2. Compared with the center channel reinforcement beam that runs through the front panel lower cross beam and / or the front floor cross beam in the front-to-back direction, the length of the center channel reinforcement beam 3 in the front-to-back direction is optimized, the weight and manufacturing cost of the vehicle 100 are reduced, and the bottom space of the rear row of the cab is more spacious, thereby improving riding comfort.
[0038] It can be understood that the front floor cross beam 2 adopts an integrated structure. Compared with two front floor cross beams respectively connected to the left and right sides of the center channel reinforcement beam, the front floor cross beam 2 has better integrity, thereby strengthening the support for the center channel reinforcement beam 3, thereby reducing the overall deformation of the front structure 10 of the vehicle and protecting the safety of the occupants.
[0039] According to the front structure 10 of the vehicle of the embodiment of the utility model, a front floor cross beam 2 is provided, and the middle channel reinforcement beam 3 is provided between the front enclosure lower cross beam 1 and the front floor cross beam 2, the front end of the middle channel reinforcement beam 3 is connected to the front enclosure lower cross beam 1, and the rear end of the middle channel reinforcement beam 3 is connected to the front floor cross beam 2. Thus, the length of the middle channel reinforcement beam 3 along the front and rear directions is optimized, the weight and manufacturing cost of the vehicle 100 are reduced, and the bottom space of the rear row of the cab is made more spacious, and the riding comfort is improved. It also makes the integrity of the front floor cross beam 2 better, thereby strengthening the support for the middle channel reinforcement beam 3, thereby reducing the overall deformation of the front structure 10 of the vehicle and protecting the safety of the occupants.
[0040] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the front structure 10 of the vehicle also includes: a reinforcing longitudinal beam 4, which is arranged between the front enclosure lower cross beam 1 and the front floor cross beam 2, the front end of the reinforcing longitudinal beam 4 is connected to the front enclosure lower cross beam 1, the rear end of the reinforcing longitudinal beam 4 is connected to the front floor cross beam 2, and the center channel reinforcing beam 3 and the reinforcing longitudinal beam 4 are arranged at intervals in the left-right direction.
[0041] It can be understood that by providing the reinforcing longitudinal beam 4, when the front of the vehicle 100 is hit, the center channel reinforcing beam 3 and the reinforcing longitudinal beam 4 can jointly bear and transmit the collision force, thereby increasing the force transmission path between the front lower cross beam 1 and the front floor cross beam 2, and can better transmit and disperse the collision energy, thereby further reducing the overall deformation of the front structure 10 of the vehicle and protecting the safety of the occupants.
[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the reinforcing longitudinal beam 4 includes a first longitudinal beam 41 and a second longitudinal beam 42, the front end of the first longitudinal beam 41 is connected to the front enclosure lower cross beam 1, the rear end of the first longitudinal beam 41 is connected to the front floor cross beam 2, the front end of the second longitudinal beam 42 is connected to the front enclosure lower cross beam 1, the rear end of the second longitudinal beam 42 is connected to the front floor cross beam 2, the first longitudinal beam 41 and the second longitudinal beam 42 are respectively arranged on the left and right sides of the middle channel reinforcing beam 3 and are spaced apart from the middle channel reinforcing beam 3.
[0043] It can be understood that when the front of the vehicle 100 is hit, the center channel reinforcement beam 3, the first longitudinal beam 41 and the second longitudinal beam 42 can jointly bear and transmit the collision force, so that there are three force transmission paths between the front panel lower cross beam 1 and the front floor cross beam 2, thereby increasing the force transmission paths between the front panel lower cross beam 1 and the front floor cross beam 2, and being able to better transmit and disperse the collision energy, thereby further reducing the overall deformation of the front structure 10 of the vehicle and protecting the safety of the occupants.
[0044] In addition, the first longitudinal beam 41 and the second longitudinal beam 42 are respectively arranged on the left and right sides of the central channel reinforcement beam 3 and are spaced apart from the central channel reinforcement beam 3, so that the force is transmitted more evenly in the left and right directions, so that the front lower cross beam 1 and the front floor cross beam 2 are evenly stressed in the left and right directions, thereby avoiding excessive force on one side of the left and right sides of the front structure 10 of the vehicle, resulting in excessive difference in deformation between the left and right sides, thereby further reducing the overall deformation of the front structure 10 of the vehicle and protecting the safety of the occupants.
[0045] In some embodiments of the utility model, the reinforcing longitudinal beam 4 is connected to the front enclosure lower cross beam 1 and the front floor cross beam 2 by FDS (Flow Drill Screw), aluminum spot welding and structural adhesive. Thus, the connection reliability between the reinforcing longitudinal beam 4 and the front enclosure lower cross beam 1 and the front floor cross beam 2 is improved, thereby improving the overall strength of the front structure 10 of the vehicle, thereby further reducing the overall deformation of the front structure 10 of the vehicle and protecting the safety of the occupants.
[0046] In some embodiments of the present invention, Figure 3As shown, the outer contour of the cross section of the front lower cross beam 1 perpendicular to the left and right direction is a trapezoid, so that the front lower cross beam 1 is conveniently well fitted and connected with other structures of the vehicle 100, thereby improving the overall structural strength of the vehicle 100.
[0047] Among them, Figure 3 In the example shown, in the trapezoidal outer contour of the cross section of the dash lower cross member 1 perpendicular to the left-right direction, one of the oblique sides of the trapezoid is parallel to the up-down direction of the vehicle 100, the other oblique side is parallel to the front-back direction of the vehicle 100, and the oblique side parallel to the up-down direction of the vehicle 100 is located in front of the other oblique side. However, the present invention is not limited to this, and the outer contour of the cross section of the dash lower cross member 1 perpendicular to the left-right direction may also be other trapezoidal shapes.
[0048] In some embodiments of the present invention, Figure 3 As shown, there is a first cavity 12 in the front enclosure lower cross beam 1, and the first cavity 12 penetrates the front enclosure lower cross beam 1 along the length direction of the front enclosure lower cross beam 1. There is at least one first reinforcing rib 11 in the first cavity 12, and at least one first reinforcing rib 11 divides the first cavity 12 into a plurality of first sub-cavities 121, and each first sub-cavity 121 penetrates the front enclosure lower cross beam 1 along the length direction of the front enclosure lower cross beam 1.
[0049] It can be understood that the provision of multiple first sub-cavities 121 enables the front lower cross beam 1 to effectively isolate vibration and noise and improve NVH (Noise, Vibration and Harshness) performance, and the provision of at least one first reinforcing rib 11 in the first cavity 12 can further improve the structural strength of the front lower cross beam 1, thereby improving the structural strength of the vehicle's front structure 10, thereby further reducing the overall deformation of the vehicle's front structure 10 and protecting the safety of the occupants.
[0050] For example, Figure 3 In the example shown, there are three first reinforcing ribs 11 and four first sub-cavities 121, but the present invention is not limited thereto. The first reinforcing ribs 11 may be other numbers, and the first sub-cavities 121 may be other numbers. For example, the first reinforcing ribs 11 may be 1, 2, 5 or 6, etc., and the first sub-cavities 121 may be 2, 3, 6 or 7, etc. It should be noted that the number of the first sub-cavities 121 is the number of the first reinforcing ribs 11 plus one.
[0051] In some embodiments of the present invention, Figure 3As shown, the front floor cross beam 2 has a second cavity 22, and the second cavity 22 penetrates the front floor cross beam 2 along the length direction of the front floor cross beam 2. The second cavity 22 has at least one second reinforcing rib 21, and the at least one second reinforcing rib 21 divides the second cavity 22 into a plurality of second sub-cavities 221, and each second sub-cavity 221 penetrates the front floor cross beam 2 along the length direction of the front floor cross beam 2.
[0052] It can be understood that the provision of multiple second sub-cavities 221 enables the front floor beam 2 to effectively isolate vibration and noise and improve NVH performance, and the provision of at least one second reinforcing rib 21 in the second cavity 22 can further improve the structural strength of the front floor beam 2, thereby improving the structural strength of the front structure 10 of the vehicle, thereby further reducing the overall deformation of the front structure 10 of the vehicle and protecting the safety of the occupants.
[0053] For example, Figure 3 In the example shown, there is one second reinforcing rib 21 and two second sub-cavities 221, but the present invention is not limited thereto. The second reinforcing rib 21 may be other numbers, and the second sub-cavities 221 may also be other numbers. For example, the second reinforcing rib 21 may be 2, 3, 5 or 6, etc., and the second sub-cavities 221 may be 3, 4, 6 or 7, etc. It should be noted that the number of the second sub-cavities 221 is the number of the second reinforcing rib 21 plus one.
[0054] In some embodiments of the present invention, the middle channel reinforcement beam 3 is an aluminum alloy part; it should be noted that the aluminum alloy part has low material density and high structural strength. The middle channel reinforcement beam 3 is an aluminum alloy part, which can reduce the weight of the middle channel reinforcement beam 3 while ensuring the structural strength of the middle channel reinforcement beam 3 to protect the safety of the occupants.

Thus, the connection reliability between the central channel reinforcement beam 3 and the front enclosure lower cross beam 1 and the front floor cross beam 2 is improved, thereby further improving the overall strength of the front structure 10 of the vehicle, thereby further reducing the overall deformation of the front structure 10 of the vehicle, and protecting the safety of the occupants.
