[0032] In the related art, the vehicle's cabin longitudinal beams and floor are respectively arranged on both sides of the front panel, and the cabin longitudinal beams are connected to the front panel through the front panel cross beam. When the vehicle is collided in the length direction, the cabin longitudinal beams will drive the front panel to invade the cockpit. In the prior art, the floor and the cabin longitudinal beams are spaced apart in the height direction. When the front panel invades toward the cockpit, the floor only blocks the bottom of the front panel, and the blocking ability of the front panel when invading is limited.

[0033] Reference below Figure 1-Figure 3 A cowl assembly 1 for a vehicle according to an embodiment of the present invention is described.

[0034] like Figure 1-Figure 3 As shown, the dash assembly 1 according to the utility model comprises: a dash panel, a cabin longitudinal beam 20, a floor 30, a middle channel assembly 40 and a connecting member 50. The cabin longitudinal beam 20 is arranged at the front side of the dash panel, the floor 30 is arranged at the rear side of the dash panel, the middle channel assembly 40 is arranged on the floor 30 and connected to the dash panel, one end of the connecting member 50 is connected to the dash panel, the other end of the connecting member 50 is connected to the middle channel assembly 40, and one end of the connecting member 50 is arranged at a side away from the other end of the floor 30. It is worth noting that the cross section of the middle channel assembly 40 is also in the shape of a "J", and its opening is arranged downward, and the middle channel assembly 40 can be welded to the floor 30, and the middle channel assembly 40 is conducive to the absorption and transmission of collision energy.

[0035] In some embodiments, the thickness direction of the front panel is parallel to the length direction of the vehicle, a cabin longitudinal beam 20 is provided on one side of the front panel in the thickness direction, and a floor 30 is provided on the other side of the front panel in the thickness direction. The floor 30 and the front panel jointly define a cockpit, and the floor 30 and the cabin longitudinal beam 20 are spaced apart from each other in the height direction. A middle channel assembly 40 is provided on the floor 30, and the middle channel assembly 40 extends in the length direction of the vehicle, and one end of the middle channel assembly 40 in the length direction of the vehicle is connected to the front panel, and the connecting member 50 extends obliquely in the height direction (the distance from one end of the connecting member 50 to the floor 30 is greater than the distance from the other end of the connecting member 50 to the floor 30), and one end of the connecting member 50 is connected to the front panel, and the other end of the connecting member 50 is connected to the middle channel assembly 40, that is, the connection point between the middle channel assembly 40 and the front panel is located above the connection point between the connecting member 50 and the front panel.

[0036] It is understandable that when the vehicle is hit head-on, the cabin longitudinal beam 20 will invade toward the cockpit, and the cabin longitudinal beam 20 will drive the front panel to invade toward the cockpit. At this time, in the height direction, the force received by the front panel from the cabin longitudinal beam 20 is divided into two parts and transmitted to the middle channel assembly 40, one part of which is suitable for being directly transmitted to the middle channel assembly 40, and the other part of which is suitable for being indirectly transmitted to the middle channel assembly 40 through the connecting member 50. As a result, the force received by the front panel can be better transmitted to the middle channel assembly 40, that is, the cooperation between the middle channel assembly 40 and the connecting member 50 can better support the front panel, thereby reducing the amount of invasion of the front panel.

[0037] According to the front panel assembly 1 involved in the present invention, the two ends of its connecting member 50 are respectively connected to the front panel and the middle channel assembly 40, and the connection point between the connecting member 50 and the front panel is located above the middle channel assembly 40, so that when the front panel invades toward the cockpit, the force exerted on the front panel can be transmitted to the middle channel assembly 40 in two parts in the height direction, so that the force exerted on the front panel can be transmitted to the middle channel assembly 40 more smoothly, thereby reducing the intrusion amount of the front panel, improving the structural strength of the vehicle in the length direction, and thus improving the vehicle's frontal impact resistance.

[0038] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the dash panel includes: a plate body 11 and a dash panel cross beam 12, wherein the dash panel cross beam 12 extends in the width direction of the vehicle and is connected to the cabin longitudinal beam 20; wherein a connecting portion is provided on the side of the plate body 11 away from the dash panel cross beam 12, wherein the projection of the connecting portion in the length direction of the vehicle at least partially overlaps with the dash panel cross beam 12, and the connecting portion is suitable for connection with the connecting member 50.

[0039] In some embodiments, the two sides of the plate body 11 in the thickness direction are respectively constructed as a cabin and a cockpit, and the side of the plate body 11 facing the cabin is connected to a dash panel cross beam 12, and the dash panel cross beam 12 is suitable for connecting to the cabin longitudinal beam 20, and the side of the plate body 11 facing the cockpit is connected to the center channel assembly 40, and a connecting portion is provided on the side of the plate body 11 facing the cockpit, and the connecting portion is suitable for connecting to a connecting piece 50, and the projection of the connecting portion in the length direction of the vehicle at least partially overlaps with the dash panel cross beam 12.

[0040] It can be understood that the cabin longitudinal beam 20 is connected to the plate body 11 through the dash cross beam 12, and the dash cross beam 12 is suitable for increasing the contact area between the cabin longitudinal beam 20 and the plate body 11, so as to avoid the plate body 11 being damaged due to excessive local stress on the plate body 11, that is, the dash cross beam 12 is suitable for increasing the force transmission area of ​​the cabin longitudinal beam 20, so as to avoid the plate body 11 being subjected to large local stress. After the plate body 11 receives the force from the dash cross beam 12, part of the force is directly transmitted to the middle channel assembly 40, and the other part of the force is transmitted to the middle channel assembly 40 through the connecting member 50, and because the projection of the connecting part in the vehicle length direction at least partially overlaps with the dash cross beam 12, the connecting member 50 can directly transmit part of the force received by the dash cross beam 12 to the middle channel assembly 40, further improving the force transmission effect of the dash in the vehicle length direction, thereby further reducing the intrusion amount of the dash when the vehicle is hit head-on.

[0041] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the connecting member 50 includes: a first split portion 51 and a second split portion 52, one end of the first split portion 51 is connected to the connecting portion, one end of the second split portion 52 is connected to the other end of the first split portion 51, and the other end of the second split portion 52 is connected to the middle channel assembly 40; wherein the angle between the first split portion 51 and the second split portion 52 is α, satisfying: 140°≤α≤160°.

[0042] It is understandable that the angle between the first split portion 51 and the second split portion 52 satisfies 140°≤α≤160°, and optionally, α can be 141°, 145°, 150°, 155°, 159°, etc., which is not limited here. It is worth noting that the line connecting one end and the other end of the connecting member 50 is configured as a connecting line. Therefore, through the above arrangement, the connection between the first split portion 51 and the second split portion 52 is convex away from the midpoint of the connecting line, thereby preventing the connecting member 50 from rotating and bending during the force transmission process.

[0043] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, there are two connecting members 50 , and the two connecting members 50 are respectively arranged on both sides of the middle channel component 40 in the width direction.

[0044] It can be understood that the same-side ends of the two connecting members 50 are respectively connected to the plate body 11, and the other same-side ends of the two connecting members 50 are respectively connected to the two side walls of the middle channel assembly 40 in the vehicle width direction. Since the two side walls of the middle channel assembly 40 in the vehicle width direction extend in the vehicle height direction, the two side walls of the middle channel assembly 40 in the vehicle width direction have high structural strength in the vehicle height direction. That is, the above-mentioned arrangement can prevent the connecting members 50 from deforming the middle channel assembly 40 during the transmission process, and the two connecting members 50 cooperate to transmit the force exerted on the plate body 11 to the middle channel assembly 40, thereby preventing the force exerted on the middle channel assembly 40 from being concentrated, and further preventing the deformation of the middle channel assembly 40.

[0045] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the first split portion 51 is provided with a first weight-reducing hole 511 penetrating in the thickness direction, and the second split portion 52 is provided with a second weight-reducing hole 521 penetrating in the thickness direction and communicating with the first weight-reducing hole 511. It can be understood that the first weight-reducing hole 511 is suitable for reducing the weight of the first split portion 51, and the second weight-reducing hole 521 is suitable for reducing the weight of the second split portion 52, that is, the first weight-reducing hole 511 and the second weight-reducing hole 521 cooperate to reduce the weight of the connecting member 50, thereby achieving lightweighting of the vehicle.

[0046] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the connector 50 further includes: a reinforcing flange 53, which is connected to the inner circumferential wall of the first weight-reducing hole 511 and the second weight-reducing hole 521, respectively. It can be understood that the first weight-reducing hole 511 and the second weight-reducing hole 521 will reduce the structural strength of the connector 50, and thus, the inner walls of the first weight-reducing hole 511 and the second weight-reducing hole 521 of the present application are respectively provided with reinforcing flanges 53, and the reinforcing flanges 53 extend in the thickness direction of the connector 50 (the extension direction of the reinforcing flange 53 can be parallel to or intersect with the thickness direction of the connector 50, which is not limited here, and the thickness direction of the connector 50 is parallel to the width direction of the vehicle), and thus, the reinforcing flange 53 can enhance the structural strength of the connector 50, improve the anti-bending ability of the connector 50, avoid bending of the connector 50 during the force transmission process, and improve the force transmission ability of the connector 50.

[0047] According to some embodiments of the present invention, Figure 1-Figure 3As shown, the dash assembly 1 further includes: a reinforcing plate 13, which is arranged at the connecting portion, and is suitable for connecting the connecting member 50 with the plate body 11. It can be understood that the connecting portion is suitable for transmitting part of the force of the dash cross beam 12 to the connecting member 50, so that the plate body 11 is subjected to a large force at the connecting portion. The present application arranges the reinforcing plate 13 at the connecting portion, and the side of the reinforcing plate 13 facing away from the plate body 11 is suitable for connecting with the connecting member 50, and the reinforcing plate 13 is suitable for strengthening the structural strength of the connecting portion, thereby preventing the connecting portion from being deformed or even damaged by a large force.

[0048] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, both ends of the dash panel cross beam 12 extend to connect with two A-pillars 60 of the vehicle respectively. It can be understood that after the dash panel cross beam 12 receives the force from the cabin longitudinal beam 20, the dash panel cross beam 12 is suitable for directly transmitting a part of the force to the plate body 11, and at the same time, the dash panel cross beam 12 is also suitable for directly transmitting another part of the force to the two A-pillars 60, reducing the force received by the plate body 11, and at the same time, the above arrangement can make the force received by the dash panel cross beam 12 more smoothly transmitted in the vehicle width direction, further reducing the intrusion amount of the dash panel.

[0049] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the dash assembly 1 further includes: a sill beam 70, which is configured as two sill beams extending in the length direction of the vehicle, and the two sill beams 70 are respectively connected to the two A-pillars 60 of the vehicle. It can be understood that the two sill beams 70 are respectively arranged on both sides of the vehicle in the width direction, and the two sill beams 70 extend in the length direction of the vehicle and are respectively connected to the two A-pillars 60, so that the two A-pillars 60 are suitable for transmitting the force of the dash cross beam 12 to the two sill beams 70, so that the force transmission structure of the vehicle in the length direction is better.
