Description

Technical Field

[0002] The front longitudinal beam of a vehicle is an important force transmission channel during a vehicle collision. As the vehicle's collision performance requirements gradually increase, an additional upper side beam is added as an auxiliary force transmission channel in the vehicle. The front longitudinal beam and the upper side beam are connected by a connecting structure so that the front longitudinal beam and the upper side beam can cooperate to form a force transmission channel, enabling each force transmission channel to cooperate to gradually crush and absorb energy and transfer the remaining energy to areas such as the A-pillar and the door sill of the vehicle, thereby improving the vehicle's collision performance.

[0003] In the related art, when the front longitudinal beam and the upper side beam are connected by a connecting structure, the connection strength performance between the connecting structure and the front longitudinal beam and the upper side beam is insufficient, resulting in the vehicle being prone to tearing at the connection position.

[0049] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0050] Next, refer to Figures 1 - 18 to describe the front body structure 100 according to the first aspect embodiment of the present utility model.

[0051] As Figures 1 - 18 shown, the front body structure 100 according to the first aspect embodiment of the present utility model includes: a front longitudinal beam 10, an upper side beam 40, and a connecting beam 30.

[0052] Specifically, the front longitudinal beam 10 has a first mating surface 101 and a second mating surface 102 connected at an angle; the upper side beam 40 has a third mating surface 401 and a fourth mating surface 402 connected at an angle; the connecting beam 30 is connected to the front longitudinal beam 10 and the upper side beam 40. The connecting beam 30 includes: a first connecting plate 31, a second connecting plate 32, and a beam body 33. The two ends of the beam body 33 are respectively connected to the first connecting plate 31 and the second connecting plate 32. The first connecting plate 31 is respectively attached to the first mating surface 101 and the second mating surface 102 and fixedly connected to the front longitudinal beam 10. The second connecting plate 32 is respectively attached to the third mating surface 401 and the fourth mating surface 402 and fixedly connected to the upper side beam 40.

[0053] In this embodiment, the connecting beam 30 is arranged to be connected to the front longitudinal beam 10 and the upper side beam 40. The connecting beam 30 is formed into a connecting structure between the front longitudinal beam 10 and the upper side beam 40. When a vehicle collides, the impact force generated by the collision can be transmitted along the front longitudinal beam 10 to structures such as the A-pillar and the sill of the vehicle. The impact force can also be transmitted along the front longitudinal beam 10 and the connecting beam 30 to the upper side beam 40 and then to structures such as the A-pillar and the sill of the vehicle. The front longitudinal beam 10, the connecting beam 30, and the upper side beam 40 can be gradually crushed to absorb energy to reduce the impact force transmitted to positions such as the A-pillar and the sill, thereby reducing the degree of deformation of the occupant compartment and providing collision protection for the driver and passengers in the vehicle.

[0054] In this embodiment, the connecting beam 30 includes a first connecting plate 31, a second connecting plate 32, and a beam body 33. The two ends of the beam body 33 are respectively connected to the first connecting plate 31 and the second connecting plate 32. The first connecting plate 31 is attached to and fixedly connected to the first mating surface 101 and the second mating surface 102 of the front longitudinal beam 10. Since the first mating surface 101 and the second mating surface 102 are connected at an angle, the first connecting plate 31 can correspondingly be formed into an L-shaped connecting plate structure. When the first connecting plate 31 is connected and fixed to the front longitudinal beam 10, the first connecting plate 31 can be stably and reliably clamped and fixed on the front longitudinal beam 10 by fitting with the first mating surface 101 and the second mating surface 102, thereby making the connection and fixation between the first connecting plate 31 and the front longitudinal beam 10 more stable.

[0055] When a vehicle collides, the impact force can be transmitted to the connecting beam 30 along the part where the first connecting plate 31 fits with the first mating surface 101 and the second mating surface 102, so that the impact force is well dispersed at the connection position between the first connecting plate 31 and the front longitudinal beam 10. Moreover, since the first connecting plate 31 is fixedly connected by fitting with the first mating surface 101 and the second mating surface 102, the first connecting plate 31 and the front longitudinal beam 10 can have a large connection contact area, thereby making the connection structure strength between the connecting beam 30 and the front longitudinal beam 10 higher, greatly reducing the probability of tearing and separation between the first connecting plate 31 and the front longitudinal beam 10, making the overall structure of the connecting beam 30 and the front longitudinal beam 10 more stable and reliable, and enabling the connecting beam 30 and the front longitudinal beam 10 to cooperate to form a stable and reliable force transmission channel, so that the vehicle can have good collision performance.

[0056] Similar to the first connecting plate 31, in this embodiment, the second connecting plate 32 is attached and fixed to the third mating surface 401 and the fourth mating surface 402 of the upper side beam 40, so that the second connecting plate 32 and the upper side beam 40 can form a more stable and reliable connection structure, enabling the impact force to be dispersed and transmitted to the upper side beam 40 along the portion where the second connecting plate 32 is in contact with the third mating surface 401 and the portion where the second connecting plate 32 is in contact with the fourth mating surface, thereby making the connection structure between the second connecting plate 32 and the upper side beam 40 have better strength, so that the connecting beam 30 and the upper side beam 40 can cooperate to form a stable and reliable force transmission path, and thus making the collision performance of the vehicle better.

[0057] In this embodiment, the connecting beam 30 is connected and fixed to the front longitudinal beam 10 and the upper side beam 40 by providing the first connecting plate 31 and the second connecting plate 32 respectively. The first connecting plate 31 is in contact with the first mating surface 101 and the second mating surface 102, and the first connecting plate 31 can be riveted or fixedly connected to the first mating surface 101 and the second mating surface 102. The second connecting plate 32 is in contact with the third mating surface 401 and the fourth mating surface 402, and the second connecting plate 32 can be riveted or fixedly connected to the third mating surface 401 and the fourth mating surface 402.

[0060] In this embodiment, the first connecting plate 31 is provided with a first plate portion 311 and a second plate portion 312. The first plate portion 311 extends along the extending direction of the front longitudinal beam 10 and fits with the first mating surface 101. The structure is simple, enabling the first plate portion 311 to form a relatively large connecting contact surface with the first mating surface 101, making it more convenient and reliable for the first plate portion 311 and the first mating surface 101 to be assembled and fixed. The second plate portion 312 extends along the extending direction of the front longitudinal beam 10 and fits with the second mating surface 102.

[0062] In this embodiment, the second connecting plate 32 is provided with a third plate portion 321 and a fourth plate portion 322. The third plate portion 321 extends along the extending direction of the upper side beam 40 and fits with the third mating surface 401. The structure is simple, enabling the third plate portion 321 to form a relatively large connecting contact surface for cooperation with the third mating surface 401, making it more convenient and reliable for the third plate portion 321 and the third mating surface 401 to be assembled and fixed.

The cooperation between the third plate portion 321 and the fourth plate portion 322 enables the second connecting plate 32 to be stably and reliably connected and fixed to the upper side beam 40.

[0063] In some embodiments of the present utility model, referring to Figure 1 and Figure 4 as shown, the first connecting plate 31 may include: a first plate portion 311 and a second plate portion 312.

Both the third plate portion 321 and the fourth plate portion 322 extend along the extending direction of the upper side beam 40 and respectively fit with the third mating surface 401 and the fourth mating surface 402.

The structure is simple and the assembly is convenient.

[0065] In some embodiments of the present utility model, with reference to Figure 4 and Figure 8 as shown, first mating holes may be provided on both the first mating surface 101 and the second mating surface 102. The first connecting plate 31 is provided with a first assembly hole 301.

[0073] In some embodiments of the present utility model, referring to Figure 4 , Figure 8 and Figure 9 as shown, first mating holes may be provided on both the first mating surface 101 and the second mating surface 102. A first assembly hole 301 is provided on the first connecting plate 31. The first connecting plate 31 and the front longitudinal beam 10 are fixedly connected by a first fastener 61 passing through the first assembly hole 301 and the first mating hole; second mating holes are provided on both the third mating surface 401 and the fourth mating surface 402.

[0075] In some embodiments of the present utility model, referring to Figure 6 and Figure 7 as shown, the beam body 33 extends in a straight line. In the extending direction of the beam body 33, the cross-section of the beam body 33 is the same everywhere.

[0076] In this embodiment, the beam body 33 is arranged to extend in a straight line and the cross-section of the beam body 33 is the same everywhere, so that the beam body 33 can be formed by cutting a continuous workpiece during production and processing. Specifically, the production equipment can produce workpieces with the same cross-sectional dimensions as the beam body 33, and the workpieces are then formed into the required beam body 33 through cutting, etc. It can be understood that in vehicles of different models, the arrangement positions of the front longitudinal beam 10 and the upper side beam 40 are different. When the connecting beam 30 is connected and fixed to the front longitudinal beam 10 and the upper side beam 40, the lengths of the beam bodies 33 of the connecting beam 30 are different. Since the first connecting plate 31 and the second connecting plate 32 extend along the extending directions of the front longitudinal beam 10 and the upper side beam 40 respectively, the connection and fixation angles of the beam body 33 with the first connecting plate 31 and the second connecting plate 32 are also different.

[0077] In this embodiment, the beam body 33 is arranged to extend along a straight line and has the same cross-section everywhere. When the beam body 33 is produced and processed, the workpiece can be cut according to the connection requirements to form the beam body 33 with the required length, which can meet the usage requirements of different vehicle models. Thus, new molds for the connecting beam 30 can be avoided, the production cost can be well reduced, and the needs of platformization can be met, making it compatible with multiple vehicle models.

[0078] In some embodiments of the present utility model, referring to Figure 4 and Figure 6 as shown, mating grooves that are recessed towards the middle can be respectively formed at both ends of the beam body 33, and the first connecting plate 31 and the second connecting plate 32 are respectively fixed in the mating grooves.

[0079] In this embodiment, mating grooves that cooperate with the first connecting plate 31 and the second connecting plate 32 are respectively formed at both ends of the beam body 33, making it more convenient for the beam body 33 to be connected and assembled with the first connecting plate 31 and the second connecting plate 32, and the connection and fixation more stable. The mating grooves are arranged as grooves that are recessed towards the middle, which can enable the beam body 33 to have a larger connection contact surface with the first connecting plate 31 and the second connecting plate 32. Thus, the connection structural strength between the beam body 33 and the first connecting plate 31 and the second connecting plate 32 is higher, making the overall structural strength of the connecting beam 30 better and more stable. Therefore, the connecting beam 30 can be stably and reliably connected to the front longitudinal beam 10 and the upper side beam 40.

[0080] In some embodiments of the present utility model, referring to Figure 6 and Figure 7 as shown, the beam body 33 may include: a main body portion 331 and a reinforcing rib 332. The main body portion 331 forms a cavity, and the reinforcing rib 332 is arranged in the cavity. The two ends of the reinforcing rib 332 in the width direction are respectively connected to two opposite side walls in the cavity.

[0081] In this embodiment, the beam body 33 includes the main body portion 331 and the reinforcing rib 332. The main body portion 331 forms a cavity, with a simple structure, which can reduce the weight of the beam body 33 and meet the needs of vehicle lightweighting. The reinforcing rib 332 is arranged in the cavity, which can enhance the structural strength of the main body portion 331. Specifically, the two ends of the reinforcing rib 332 in the width direction are respectively connected to two opposite side walls in the cavity. Specifically, the reinforcing rib 332 extends along the extension direction of the beam body 33, and the two ends of the reinforcing rib 332 in the width direction are respectively connected to two opposite side walls of the cavity, thereby dividing the cavity into multiple smaller cavities, making the overall stiffness of the beam body 33 larger and the bending resistance performance of the beam body 33 higher.

[0082] In this embodiment, a reinforcing rib 332 is arranged in the cavity. The structure is simple, making the overall beam body 33 more compact. The reinforcing rib 332 can cooperate with the main body portion 331 to form a force transmission structure, enabling the beam body 33 to more stably transmit impact force.

[0083] In an embodiment of the present utility model, referring to Figure 7 As shown, the number of the reinforcing ribs 332 can be multiple, and the multiple reinforcing ribs 332 intersect at an angle.

[0084] In this embodiment, multiple reinforcing ribs 332 are arranged, and the multiple reinforcing ribs 332 intersect at an angle. As a result, under the partitioning action of the multiple reinforcing ribs 332, the cavity forms more and smaller cavity structures, making the overall structural strength of the beam body 33 higher and the bending resistance performance stronger, enabling the connecting beam 30 to more stably and reliably transmit impact force, and further improving the collision performance of the vehicle. For example, the number of the reinforcing ribs 332 can be two, three, four, etc.

[0085] In some examples of the present utility model, such as Figure 7 As shown, the number of the reinforcing ribs 332 can be two, and the two reinforcing ribs 332 can intersect at a right angle. In this embodiment, setting the number of the reinforcing ribs 332 to two can enable the two reinforcing ribs 332 to cooperate to increase the structural strength of the beam body 33, making the beam body 33 have good bending resistance performance, and avoiding excessive weight and excessive material consumption of the beam body 33 caused by too many reinforcing ribs 332. Thus, the connecting beam 30 can meet the lightweight design requirements and has a relatively low production cost, with good economic efficiency.

[0086] In this embodiment, the two reinforcing ribs 332 intersect at a right angle, so that the cross-section of the beam body 33 in the extending direction can be formed into a cross-shaped structure, making the beam body 33 have good bending resistance performance. Exemplarily, the cross-sectional shape of the main body portion 331 can be set as required, and the positions of the two ends of the reinforcing rib 332 on the side wall of the cavity can also be set as required. For example, the shape of the main body portion 331 can be rectangular, hexagonal, etc. The two ends of the reinforcing rib 332 can be connected to the middle position of the side wall of the cavity or can be set to deviate from the middle position. The two ends of the reinforcing rib 332 can also be connected to the position where two adjacent side walls of the cavity are connected, as well as other structural arrangement forms, which are not specifically limited here.

[0087] In some examples of the present utility model, the thickness of the reinforcing rib 332 can be less than the wall thickness of the main body portion 331.

[0088] In this embodiment, setting the thickness of the reinforcing rib 332 to be less than the wall thickness of the main body portion 331 can further reduce the weight of the beam body 33 while meeting the requirements of the structural strength and stiffness of the beam body 33, so that the connecting beam 30 uses less material and has lower cost during production and processing.

[0089] In some embodiments of the present utility model, the connecting beam 30 may be an aluminum alloy part. In this embodiment, setting the connecting beam 30 as an aluminum alloy part can be lighter in weight while meeting the requirements such as the stiffness and structural strength of the connecting beam 30, so as to better meet the need for vehicle weight reduction. Moreover, the connecting beam 30 can be produced and processed by the aluminum alloy extrusion process, reducing the tooling cost and shortening the production cycle during the production and processing of the connecting beam 30, thereby making the production cost of the front body structure 100 lower and the production efficiency higher.

In this embodiment, the side beam reinforcement plate 50 and the upper side beam 40 are riveted by rivets, which facilitates the assembly and fixation of the side beam reinforcement plate 50 and the upper side beam 40, makes the connection and fixation of the side beam reinforcement plate 50 and the upper side beam 40 stable and reliable, and enables the second connecting plate 32 to be reliably fastened to the side beam reinforcement plate 50 and the upper side beam 40.

[0100] As Figures 1 - 18 shown, the vehicle according to the embodiment of the present utility model includes a front body structure 100 according to the embodiment of the first aspect of the present utility model.

[0101] Other components and operations of the vehicle according to the embodiment of the present utility model are known to those of ordinary skill in the art and will not be described in detail here.

[0102] For the vehicle according to the embodiment of the present utility model, by providing the front body structure 100 of the above-mentioned first aspect embodiment, the front body structure 100 is provided with a connecting beam 30 connected to the front longitudinal beam 10 and the upper side beam 40. The first connecting plate 31 of the connecting beam 30 is attached to and fixedly connected to the first mating surface 101 and the second mating surface 102 of the front longitudinal beam 10, and the second connecting plate 32 of the connecting beam 30 is attached to and fixedly connected to the third mating surface 401 and the fourth mating surface 402 of the upper side beam 40, making the connection between the connecting beam 30 and the front longitudinal beam 10 and the upper side beam 40 more stable and reliable, with higher connection strength, greatly reducing the probability of tearing and separation at the connection positions of the connecting beam 30 with the front longitudinal beam 10 and the upper side beam 40, and enabling the front longitudinal beam 10 to form a stable and reliable force transmission channel with the connecting beam 30 and the upper side beam 40, so that the vehicle can have better collision performance.

[0103] Next, will refer to Figures 1 - 18 to describe a vehicle according to a specific embodiment of the present utility model.

[0104] As Figures 1 - 18 shown, the vehicle includes a front body structure 100, and the front body structure 100 includes a front longitudinal beam 10, a longitudinal beam reinforcing plate 20, a connecting beam 30, an upper side beam 40, and a side beam reinforcing plate 50. The front longitudinal beam 10, the longitudinal beam reinforcing plate 20, the upper side beam 40, and the side beam reinforcing plate 50 are steel parts. The longitudinal beam reinforcing plate 20 is arranged on the inner side of the front longitudinal beam 10 and is riveted and fixed to the front longitudinal beam 10, and the side beam reinforcing plate 50 is arranged on the inner side of the upper side beam 40 and is riveted and fixed to the upper side beam 40.

[0105] The connecting beam 30 is made of aluminum alloy. The connecting beam 30 includes a first connecting plate 31, a beam body 33, and a second connecting plate 32. The first connecting plate 31 is an L-shaped plate. The first connecting plate 31 is fixedly connected to the front longitudinal beam 10 and the longitudinal beam reinforcing plate 20 through a first fastener 61. The second connecting plate 32 is fixedly connected to the upper side beam 40 and the side beam reinforcing plate 50 through a second fastener 62. Both the first fastener 61 and the second fastener 62 are bolts. The beam body 33 includes a main body portion 331 and reinforcing ribs 332. The main body portion 331 has a cavity. There are two reinforcing ribs 332 which are vertically intersecting. The two reinforcing ribs 332 are arranged in the cavity and cooperate with the main body portion 331 to divide the cavity into four small cavities, so that the cross-section of the beam body 33 is in a shape of a Chinese character 'tian' (square with a cross in the middle). Specifically, the two ends of the width of one of the reinforcing ribs 332 are respectively connected to two opposite angular positions formed by the inner wall surface of the cavity, so that the cross-section of the main body portion 331 is formed into a flat hexagon. The two ends of the beam body 33 can be welded to the first connecting plate 31 and the second connecting plate 32 into one body by gas shielded welding.

[0106] Both the first plate portion 311 and the second plate portion 312 of the first connecting plate 31 are provided with two first assembly holes 301. Both the third plate portion 321 and the fourth plate portion 322 of the second connecting plate 32 are provided with two second assembly holes 302. The front longitudinal beam 10 and the longitudinal beam reinforcing plate 20 are respectively provided with a first mating hole and a first through hole 21 which cooperate with the first assembly hole 301. A first nut 63 is back-welded on the longitudinal beam reinforcing plate 20. The first fastener 61 passes through the first assembly hole 301, the first mating hole, and the first through hole 21 and is threadedly connected to the first nut 63, thereby fixedly connecting the first connecting plate 31 to the front longitudinal beam 10 and the longitudinal beam reinforcing plate 20. The upper side beam 40 and the side beam reinforcing plate 50 are respectively provided with a second mating hole and a second through hole 51 which cooperate with the second assembly hole 302. A second nut 64 is back-welded on the side beam reinforcing plate 50. The second fastener 62 passes through the second assembly hole 302, the second mating hole, and the second through hole 51 and is threadedly connected to the second nut 64, thereby fixedly connecting the second connecting plate 32 to the upper side beam 40 and the side beam reinforcing plate 50.

[0107] During the production and processing process, the beam body 33 can cut the processed parts according to the connection and assembly requirements to form a beam body 33 with a length meeting the requirements, and cut mating groove structures at both ends of the beam body 33 that cooperate with the first connecting plate 31 and the second connecting plate 32. Then the beam body 33 is welded to the first connecting plate 31 and the second connecting plate 32 into a single piece, and then the subsequent assembly of the connecting beam 30 with the front longitudinal beam 10, the longitudinal beam reinforcing plate 20, the upper side beam 40, and the side beam reinforcing plate 50 is carried out. For different vehicle models, the connecting beam 30 can reasonably cut the beam body 33 according to the connection requirements between the front longitudinal beam 10 and the upper side beam 40 in different vehicle models and form corresponding mating groove shapes and other treatments, so as to meet the use requirements in different vehicle models.

[0108] During the assembly process, the longitudinal beam reinforcement plate 20 is positioned by cooperating with the limit pin and the limit hole 701 and positioned by cooperating with the positioning pin and the positioning hole 702, so as to be stably and reliably assembled in place within the front longitudinal beam 10. The longitudinal beam reinforcement plate 20 and the front longitudinal beam 10 are fixed by riveting. The side beam reinforcement plate 50 is positioned by cooperating with the limit pin and the limit hole 701 and positioned by cooperating with the positioning pin and the positioning hole 702, so as to be stably and reliably assembled in place within the upper side beam 40. The side beam reinforcement plate 50 and the upper side beam 40 are fixed by riveting.

[0109] When a vehicle collides, for example, in the case of a small overlap collision, the impact force generated by the collision is transmitted to the front longitudinal beam 10 after the energy absorption box of the front anti-collision beam assembly of the vehicle collapses and absorbs energy. Part of the impact force is transmitted along the connecting beam 30 to the upper side beam 40 and gradually transmitted to the sill and A-pillar areas, enabling the front longitudinal beam 10 and the upper side beam 40 to fully participate in the collision energy absorption process, reducing the damage to the occupant compartment, and better protecting the driver and passengers.

[0110] In this embodiment, the connecting beam 30 is provided to be connected to the front longitudinal beam 10 and the upper side beam 40. The first connecting plate 31 of the connecting beam 30 is attached to and fixedly connected to the first mating surface 101 and the second mating surface 102 of the front longitudinal beam 10. The second connecting plate 32 of the connecting beam 30 is attached to and fixedly connected to the third mating surface 401 and the fourth mating surface 402 of the upper side beam 40, making the connection between the connecting beam 30 and the front longitudinal beam 10 and the upper side beam 40 more stable and reliable, with higher connection strength. When the vehicle collides, for example, in the case of an offset collision, the connecting beam 30 can still be firmly and reliably connected to the front longitudinal beam 10 and the upper side beam 40, thus greatly reducing the probability of tearing and separation at the connection position between the connecting beam 30 and the front longitudinal beam 10 and the upper side beam 40, enabling the front longitudinal beam 10, the connecting beam 30, and the upper side beam 40 to form a stable and reliable force transmission channel, and thereby enabling the vehicle to have better collision performance.
