Description

Technical Field

[0001] This application belongs to the technical field of vehicle front panels, specifically relating to a front panel assembly and a vehicle. Background Technology

[0002] The 55 km / h frontal full-frontal collision scenario refers to a vehicle colliding head-on with a rigid wall at 55 km / h without any deviation. The entire front structure of the vehicle (the entire width from left to right) participates in the collision simultaneously. This type of collision results in a high peak deceleration, requiring optimization of the front structure of the vehicle to allow the front of the vehicle to fold and crush in an orderly manner, thereby extending the deceleration time, reducing the peak deceleration, and ensuring that parts such as the front bulkhead of the passenger compartment do not suffer severe deformation.

[0003] In some vehicles involved in related technologies, during a full frontal collision, the front bulkhead components deform at an excessively fast intrusion rate and with a large intrusion amount. This can not only cause injury to occupants but also damage other vehicle components (such as the battery pack). Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0025] refer to Figures 1 to 7 This application discloses a front bulkhead assembly 01, which is applied to a vehicle. The disclosed front bulkhead assembly 01 includes a front bulkhead panel 10, a front bulkhead crossbeam 20, a first support beam assembly 30, and a second support beam assembly 40.

[0026] The front bulkhead 10 is located at the front of the passenger compartment, serving to separate the passenger compartment from the engine compartment and providing some protection for the occupants. It should be noted that the specific structure and arrangement of the front bulkhead 10 can be referenced from existing technologies and are not specifically limited here.

[0027] The front bulkhead beam 20 is a supporting component that can support and strengthen the front bulkhead 10, thereby improving the load-bearing capacity of the front bulkhead 10 and making it less likely to deform and intrude into the passenger compartment when bearing load.

[0028] Optionally, along the longitudinal direction of the vehicle, the front bulkhead beam 20 can be arched forward to form a beam with a concave cross-section. This can both increase the space inside the passenger compartment and improve the load-bearing capacity of the front bulkhead beam 20. For example, the cross-section of the front bulkhead beam 20 can be "C" shaped.

[0029] In some embodiments, the front bulkhead beam 20 is connected to the front bulkhead panel 10. Optionally, the front bulkhead beam 20 can be fixedly connected to the front bulkhead panel 10 by welding, riveting, or other methods to ensure the stability and reliability of the connection between the front bulkhead beam 20 and the front bulkhead panel 10, which is beneficial to improving the overall strength and rigidity of the front bulkhead panel 10.

[0030] The front bulkhead beam 20 extends along the left and right direction of the vehicle to support and reinforce the front bulkhead 10 in the left and right direction of the vehicle, so as to protect the driver's seat and the passenger seat respectively, and alleviate the problem of the front bulkhead 10 intruding into the driver's seat or the passenger seat after being loaded.

[0031] The first support beam assembly 30 is connected to the front bulkhead 10 and the front bulkhead crossbeam 20 respectively. In this way, the first support beam assembly 30 can support and strengthen the front bulkhead 10 and the front bulkhead crossbeam 20 respectively, so as to further improve the strength and rigidity of the front bulkhead 10 and thus improve the load-bearing capacity of the front bulkhead 10.

[0032] Optionally, the first support beam assembly 30 and the front bulkhead 10 can be fixed by welding or riveting to ensure the reliability and stability of the connection between the first support beam assembly 30 and the front bulkhead 10. Additionally, the first support beam assembly 30 and the front bulkhead crossbeam 20 can also be fixed by welding or riveting to ensure the reliability and stability of the connection between the first support beam assembly 30 and the front bulkhead crossbeam 20.

[0033] The first support beam assembly 30 can extend along the vertical direction of the vehicle, thereby providing support and reinforcement to the front bulkhead 10 and the front bulkhead crossbeam 20 in the vertical direction of the vehicle. This, in conjunction with the support and reinforcement of the front bulkhead crossbeam 20, forms a crisscrossing support and reinforcement pattern, further improving the strength and rigidity of the front bulkhead 10 and making it less likely for the front bulkhead 10 to intrude into the passenger compartment when bearing loads.

[0034] In the front-rear direction of the vehicle, the second support beam assembly 40 can be located at the rear side of the dash panel 10 and is connected to the dash panel 10 and the front dash cross member 20 respectively. In this way, the second support beam assembly 40 can support and reinforce the dash panel 10 and the front dash cross member 20 from the rear, and cooperate with the support and reinforcement of the front dash cross member 20 and the first support beam assembly 30 to form a support and reinforcement mode interlaced in three-dimensional space of left-right, up-down and front-rear directions, which further improves the strength and rigidity of the dash panel 10, so that the dash panel 10 is not easy to intrude into the passenger compartment when bearing a load.

[0035] Optionally, fixed connection such as welding and riveting can be adopted between the second support beam assembly 40 and the dash panel 10 as well as the front dash cross member 20, and detachable connection such as screw connection can also be adopted.

[0036] Based on the above arrangement, in the embodiments of the present application, through the cooperative effect of the front dash cross member 20, the first support beam assembly 30 and the second support beam assembly 40, the dash panel 10 can be comprehensively supported and reinforced in the left-right direction, the up-down direction and the front-rear direction respectively, thereby greatly improving the load bearing capacity of the dash panel 10, avoiding large and rapid deformation during collision, reducing the intrusion speed and intrusion amount of the dash panel 10 intruding into the passenger compartment, and reducing the injury to occupants and the damage to other components of the vehicle.

[0037] Reference Figures 3 to 5 , in some embodiments, the first support beam assembly 30 may include a plurality of first dash support beams 31, the plurality of first dash support beams 31 are arranged along the left-right direction, and each first dash support beam 31 extends along the up-down direction and is connected to the dash panel 10 and the front dash cross member 20 respectively. Based on this arrangement, the plurality of first support beam assemblies 30 can respectively support and reinforce the dash panel 10 and the front dash cross member 20, and form a dispersed support and reinforcement mode, thereby increasing the support and reinforcement area for the dash panel 10 and the front dash cross member 20, and further improving the strength and rigidity of the dash panel 10.

[0038] Optionally, the region of each first dash support beam 31 near the end portion can be connected to the dash panel 10, and the end portion can be connected to the front dash cross member 20.

[0039] Optionally, the number of the first dash support beams 31 can be two, three, four, etc. Of course, it can also be other values, which can be specifically set according to actual requirements, and is not specifically limited herein.

[0040] When there are two first dash support beams 31, the two first dash support plates and the front dash cross member 20 can form a "艹"-shaped reinforcement body, for example Figure 3 , which is crisscrossed vertically and horizontally to improve the reinforcement effect.

[0041] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, each first front support beam 31 can be connected to the top of the front crossbeam 20. In this case, multiple first front support beams 31 can respectively support and reinforce the top area of ​​the front crossbeam 20 to improve the strength and rigidity of the top area of ​​the front crossbeam 20.

[0042] In other embodiments, each first front support beam 31 may be connected to the bottom of the front crossbeam 20. In this case, the multiple first front support beams 31 may respectively support and reinforce the bottom area of ​​the front crossbeam 20, thereby improving the strength and rigidity of the bottom area of ​​the front crossbeam 20.

[0043] In some other embodiments, such as Figure 3 As shown, each first front support beam 31 can also be cross-connected with the front crossbeam 20. That is, each first front support beam 31 extends in the vertical direction and passes through the front crossbeam 20. In this case, multiple first front support beams 31 can support and reinforce the top area of ​​the front crossbeam 20, as well as the bottom and middle areas of the front crossbeam 20, thereby increasing the area of ​​support and reinforcement of the front crossbeam 20, and further improving the strength and rigidity of the front crossbeam 20 and the front panel 10.

[0044] refer to Figures 4 to 7 In some embodiments, the second support beam assembly 40 may include a support frame 42 and a plurality of second front support beams 41. The plurality of second front support beams 41 are arranged in a left-right direction, and each second front support beam 41 extends in a front-rear direction and connects to the rear side of the front crossbeam 20. Thus, the plurality of second front support beams 41 can provide support and reinforcement to the front crossbeam 20 from the rear. Furthermore, by increasing the connection area in the left-right direction, the load-bearing capacity of the front crossbeam 20 can be increased, making the front crossbeam 20 less prone to bending and deformation under load during high-speed frontal collisions.

[0045] Optionally, the second front bulkhead support beam 41 can be connected to the vehicle floor 03. The second front bulkhead support beam 41 and the floor 03 can be fixed by welding, riveting, screwing, or other methods to ensure the reliability and stability of the connection. In addition, each second front bulkhead support beam 41 can be fixed to the front bulkhead crossbeam 20 by welding or riveting to ensure the reliability and stability of the connection.

[0046] One end of the support frame 42 is connected to the rear side of the front crossbeam 20, and the other end of the support frame 42 is connected to a plurality of second front support beams 41 respectively. Based on this, the support frame 42 can provide support and reinforcement between the front crossbeam 20 and the plurality of second front support beams 41, thereby further improving the load-bearing capacity of the front crossbeam 20.

[0047] Optionally, the support frame 42 and the front crossbeam 20 can be fixed by welding, riveting, screwing, etc., to ensure the reliability and stability of the connection. Additionally, the support frame 42 and each of the second front support beams 41 can be fixed by welding, riveting, screwing, etc., to ensure the reliability and stability of the connection.

[0048] refer to Figure 6 and Figure 7 In some embodiments, the support frame 42 may include multiple support crossbeams 421 and multiple support longitudinal beams 422. The multiple support longitudinal beams 422 may be arranged in a left-right direction, with one end of each support longitudinal beam 422 connected to the rear side of the front crossbeam 20, and the other end of each support longitudinal beam 422 connected to a corresponding second front support beam 41. Based on this, the support longitudinal beams 422 can provide support and reinforcement between the front crossbeam 20 and the corresponding second front support beams 41, and the multiple second front support beams 41 can distribute the load to the floor 03, thereby reducing the rearward deformation of the front assembly 01.

[0049] Based on the aforementioned support frame 42, a larger cavity can be formed below the support frame 42 to provide installation space and mounting holes for components such as the instrument panel host.

[0050] Optionally, the support longitudinal beam 422 and the front crossbeam 20 and the corresponding second front support beam 41 can be connected by welding, riveting, bolting, or other methods. For example, both the support longitudinal beam 422 and the support crossbeam 421 can be aluminum crossbeams.

[0051] Furthermore, multiple support beams 421 are arranged along the front-to-back direction, and each support beam 421 is connected between two adjacent support longitudinal beams 422. Based on this, the multiple support longitudinal beams 422 can be strengthened to improve the overall strength and rigidity of the support frame 42, thereby further enhancing the support and strengthening effect on the front bulkhead 10 and the front bulkhead beams 20.

[0052] Optionally, the supporting longitudinal beam 422 can be a straight beam or a curved beam. In some embodiments, the supporting longitudinal beam 422 can be a curved beam, and its central region (i.e., the region between the two ends) can be provided with an upwardly arched arch 4221.

[0053] To alleviate the problem of large bending deformation of the supporting longitudinal beams 422 when bearing a load, the second supporting beam assembly 40 may further include a reinforcing member 43, as Figures 4 to 7 illustrated, the reinforcing member 43 is connected to the arched portion 4221. In this way, effects of reinforcement, thickening and crack prevention can be achieved at the arched portion 4221, the deformation resistance of the supporting longitudinal beams 422 is improved, so as to prevent large bending deformation at the arched portion 4221 when the supporting longitudinal beams 422 bear a load.

[0054] In addition, after a first tension beam 44 and a second tension beam 45 described below fail, the reinforcing member can also suppress rapid upward lifting of the supporting longitudinal beams 422, thereby alleviating the problem that the dashboard assembly 01 invades the passenger compartment at an excessively high speed.

[0055] Optionally, the reinforcing member 43 may be a reinforcing plate, a reinforcing strip, a reinforcing rib or the like, and is attached to the upper surface of the arched portion 4221, so as to achieve a reinforcing effect on the arched portion 4221.

[0056] With reference to Figure 6 and Figure 7 , in some embodiments, along the front-rear direction, the distance between two adjacent supporting longitudinal beams 422 may gradually decrease from front to back. In this way, on the premise of ensuring good supporting and reinforcing effects on the dashboard cross beam 20, the distance between two adjacent second dashboard supporting beams 41 can be reduced, thereby reducing the occupied space in the passenger compartment.

[0057] For example, the projection of the supporting frame 42 in the up-down direction may be funnel-shaped. In addition, when the supporting longitudinal beam 422 is a curved beam, along the left-right direction, the side surface of the supporting frame 42 may be in an inverted L-shape With reference to Figures 4 to 7 , in some embodiments, one end of each supporting longitudinal beam 422 and the dashboard cross beam 20 can be connected by a first fastener 51, and the other end of each supporting longitudinal beam 422 and the corresponding second dashboard supporting beam 41 can be connected by a second fastener 52. Based on this arrangement, when the dashboard cross beam 20 bears a load, the joints of the first fastener 51 and the joints of the second fastener 52 can be made to fail, so that a certain buffering effect can be achieved, the situation that the dashboard assembly 01 invades into the passenger compartment at an excessively high speed is prevented, and damage to passengers is reduced.

[0058] It should be noted here that, at the joint of the first fastener 51, one end of the supporting longitudinal beam 422 and the dashboard cross beam 20 may not be attached to each other, and the shape is similar to an acute angle. In this way, the dashboard cross beam 20 is prone to tearing at the joint of the first fastener 51 due to the lever effect, which is beneficial to reducing the acceleration response of the vehicle body and reducing damage to passengers.

[0059] Similarly, at the connection of the second fastener 52, the other end of the support longitudinal beam 422 may not be in contact with the second front support beam 41, and its shape is similar to an acute angle. In this way, the second front crossbeam 20 may be easily torn at the connection of the second fastener 52 due to the leverage effect, which is beneficial to reduce the acceleration response of the vehicle body and reduce the injury to the occupants.

[0060] Optionally, the first fastener 51 and the second fastener 52 can be bolts, screws, or other components. Of course, they can also be other components, which are not specifically limited here.

[0061] refer to Figure 6 and Figure 7 In some embodiments, each supporting longitudinal beam 422 may include multiple longitudinal beam layers in the region near the front crossbeam 20, with gaps between adjacent longitudinal beam layers. This reduces the weight of the supporting longitudinal beam 422 and the amount of material used while maintaining support performance, thus reducing costs. For example, the cross-section of the supporting longitudinal beam 422 in the region near the front crossbeam 20 may be "⿲" shaped.

[0062] refer to Figures 4 to 6 In some embodiments, the second support beam assembly 40 may further include a first tie beam 44, one end of which is connected to the second front support beam 41 by a third fastener 53, and the other end of which is connected to the front panel 10 by a fourth fastener 54. The area between the two ends of the first tie beam 44 is fixedly connected to the support longitudinal beam 422.

[0063] Based on the above configuration, the front bulkhead 10, the second front bulkhead support beam 41, and the support longitudinal beam 422 can be connected together by the first tie beam 44. This can directly support and strengthen the front bulkhead 10, as well as the support longitudinal beam 422. Furthermore, the support longitudinal beam 422 can support and strengthen the front bulkhead crossbeam 20, ultimately improving the overall strength and rigidity of the front bulkhead assembly 01, making it less likely to intrude into the passenger compartment when bearing loads.

[0064] In addition, the first tie beam 44 can also pull the supporting longitudinal beam 422 to prevent the supporting longitudinal beam 422 from tilting upward, thereby maintaining support for the supporting longitudinal beam 422 and the front bulkhead 10.

[0065] In addition, the other end of the first tie beam 44 can be connected to the front bulkhead 10 by the fourth fastener 54, which can improve the rigidity of the front bulkhead 10 and help improve the NVH performance of the front cabin.

[0066] Optionally, the third fastener 53 and the fourth fastener 54 can be bolts, screws, or other components; however, no specific limitation is made here. Furthermore, the first tie beam 44 and the supporting longitudinal beam 422 can be welded or riveted together to ensure the reliability and stability of the connection.

[0067] Continue to refer to Figures 4 to 6 In some embodiments, the second support beam assembly 40 may further include a second tie beam 45, one end of which is connected to the second front support beam 41 via a fifth fastener 55, and the other end of which is connected to the support longitudinal beam 422 via a sixth fastener 56.

[0068] Based on the above configuration, the second tie beam 45 connects the supporting longitudinal beam 422 and the second front bulkhead supporting beam 41, providing support and reinforcement for the supporting longitudinal beam 422. The supporting longitudinal beam 422 further supports and reinforces the front bulkhead crossbeam 20, ultimately improving the overall strength and rigidity of the front bulkhead assembly 01, making it less prone to intrusion into the passenger compartment under load. Additionally, the second tie rod also provides tension to the supporting longitudinal beam 422, preventing it from tilting upwards and maintaining its support for the front bulkhead crossbeam 20.

[0069] Optionally, the fifth fastener 55 and the sixth fastener 56 can be bolts, screws, or other components, but no specific limitation is made here.

[0070] For example, both the first tie beam 44 and the second tie beam 45 can be aluminum tie beams.

[0071] In addition, the thickness of the first tie beam 44 and the second tie beam 45 is smaller than the thickness of the supporting longitudinal beam 422, so that it can break at the first tie beam 44 and the second tie beam 45 when subjected to a large load.

[0072] In some more specific embodiments, the support frame 42 may include two support longitudinal beams 422, and the second support beam assembly 40 may include two second front support beams 41; correspondingly, the first tie beam 44 can connect the front bulkhead 10, one of the second front support beams 41 and one of the support longitudinal beams 422 together; the second tie beam 45 can connect the other second front support beam 41 and the other support longitudinal beam 422 together.

[0073] refer to Figure 4 and Figure 5 In some embodiments, the first support beam assembly 30 may include a plurality of first front support beams 31, and correspondingly, the second support beam assembly 40 may include a plurality of second front support beams 41, and the plurality of first front support beams 31 and the plurality of second front support beams 41 may be connected to the front crossbeam 20 in a one-to-one correspondence.

[0074] Based on the above configuration, multiple force transmission paths can be formed by multiple first front support beams 31, front crossbeams 20 and multiple second front support beams 41, which is more conducive to the transmission of force.

[0075] It should be noted that multiple first front support beams 31 and multiple second front support beams 41 can be respectively set in the upper direction to form multiple force transmission paths.

[0076] Based on the aforementioned front bulkhead assembly 01, this application also discloses a vehicle, which includes the aforementioned front bulkhead assembly 01. In addition, the vehicle may also include components such as engine compartment longitudinal beams 02, floor 03, and seat crossbeams 04, etc. Figure 1 and Figure 2 As shown.

[0077] Among them, the cabin longitudinal beam 02 can be connected to the front side of the front bulkhead assembly 01 and distributed in the left and right directions; the floor 03 is located at the bottom of the rear side of the front bulkhead assembly 01 and is used to bear loads; the seat crossbeam 04 is installed on the floor 03 and is used to install the seat.

[0078] It should be noted that the specific structure and installation method of components such as cabin longitudinal beam 02, floor 03 and seat crossbeam 04 can be referred to the existing technology, and will not be elaborated here.

[0079] In summary, the embodiments of this application reduce the intrusion (or rearward movement) of the front bulkhead 10 by designing a front bulkhead assembly 01, and reduce the vehicle body acceleration, which is beneficial to protecting occupants and components such as batteries.

[0080] The front crossbeam 20, the first support beam assembly 30, and the second support beam assembly 40 provide support and reinforcement in the vertical, horizontal, and front-back directions to ensure the overall strength of the front assembly 01. Furthermore, the reinforcement member 43 thickens and strengthens the arched portion 4221 of the support longitudinal beam 422. The failure of the first tie beam 44 and the second tie beam 45 reduces the acceleration response. Moreover, when the first tie beam 44, the second tie beam 45, and various fasteners fail, the force on the floor 03 is reduced, thereby alleviating the problem of the floor 03 deforming and squeezing the battery pack.

[0081] In addition, by designing the cross section of the front beam 20 to be concave, and with the combined support of the first front support beam 31, the second front support beam 41 and the support frame 42, a small amount of intrusion can be generated in the early and middle stages of deformation of the front assembly 01. In the later stage of deformation, the front assembly 01 undergoes a large deformation. At this time, the first tie beam 44 and the second tie beam 45 may break. At the same time, the reinforcing member 43 plays a protective role for the support longitudinal beam 422, preventing the support longitudinal beam 422 from breaking at the arched part 4221.

[0082] Specifically, during the later stages of the deformation of the front bulkhead assembly 01, the first tie beam 44 and the second tie beam 45 break when the load reaches the limit, or sheet metal tears occur at the third fastener 53, the fourth fastener 54, the fifth fastener 55, and the sixth fastener 56. Subsequently, the front bulkhead crossbeam 20 deforms and flattens upward, pushing the support longitudinal beam 422 upward, thus reducing the supporting effect of the support longitudinal beam 422. At this time, the deformation of the front bulkhead assembly 01 increases, the vehicle body acceleration response decreases, thereby reducing the injury to the occupants.

[0083] In addition, after the failure of the first tie beam 44 and the second tie beam 45, the support longitudinal beam 422 tilts upward, which will apply a leverage force to the second fastener 52, causing the sheet metal at the front of the second fastener 52 to tear (i.e., the second front support beam 41), and the sheet metal at the second fastener 52 remains connected, which alleviates the problem of unstable sheet metal deformation. As a result, the support longitudinal beam 422 can no longer transmit force to the floor 03, thereby reducing the squeezing effect on the floor 03 and preventing the floor 03 from squeezing the battery pack, thus achieving the effect of protecting the battery pack.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
