A beam assembly 100 of a vehicle front floor according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 2 and 3, a beam assembly 100 of a vehicle front floor according to an embodiment of the present invention may include: a center tunnel cover 20, a left seat mounting beam 30, and a right seat mounting beam 40.

Specifically, as shown in fig. 2, the center tunnel cover 20 may extend in the front-rear direction (i.e., the X-direction of the vehicle body), and the left and right seat mounting beams 30 and 40 may be provided on the left and right sides of the center tunnel cover 20, respectively. For example, the left seat mounting beam 30 may be a left seat mounting rear cross beam and the right seat mounting beam 40 may be a right seat mounting rear cross beam. The "left side" and the "right side" are based on the Y direction of the vehicle body. Thus, the center tunnel cover 20 may be located between the left and right seat mounting beams 30, 40. For example, the left seat mounting beam 30 may be used to mount a primary driver seat and the right seat mounting beam 40 may be used to mount a secondary driver seat, which may be spaced apart by a distance on the one hand due to the extension of the center tunnel cover 20 in the fore-and-aft direction; on the other hand, it is convenient to install some functional structures such as a gear shifting mechanism, a hand brake, a driving storage box and the like on the center tunnel cover plate 20.

In some related art, left and right seat mounting beams are mounted to left and right sides of a center tunnel cover for bearing the weight of a driver seat. However, the following problems occur during driving: firstly, the rigidity of the left seat mounting beam and the right seat mounting beam is low, and the driving seat is easy to shake after being mounted; secondly, fatigue endurance risks exist in the left seat mounting beam and the right seat mounting beam; third, road noise can be degraded, greatly reducing user experience.

More seriously, this problem is more pronounced if the seat mounting beam section within the cockpit is highly compressed. For example, as shown in the electric vehicle in fig. 1, since the battery pack is disposed under the floor of the vehicle, the height of the battery pack is introduced, and in order to ensure the ground clearance of the vehicle body, the height of the whole vehicle, and the like, the height of the section of the seat mounting beam is greatly compressed, so that the seat of the electric vehicle is more prone to shake, or the risk of fatigue endurance is higher. Therefore, the problems of low rigidity of the left and right seat mounting beams of the vehicle front floor and the like have to be solved.

In the present application, as shown in fig. 2 and 3, the girder assembly 100 further includes a connection girder 50, and the connection girder 50 may be provided at an upper side of the center tunnel cover plate 20 to facilitate installation of the connection girder 50. Also, the connection beam 50 may connect the right and left seat mounting beams 40 and 30. Therefore, the left seat mounting beam 30, the connecting beam 50, and the right seat mounting beam 40 can form a multi-section beam structure, and the structural rigidity of the left seat mounting beam 30 and the right seat mounting beam 40 can be effectively improved, thereby effectively solving the problems in the related art.

Specifically, connect right seat installation roof beam 40 and left seat installation roof beam 30 through tie-beam 50, can make the structural rigidity of the roof beam subassembly 100 on floor before the vehicle greatly strengthen, and then effectively increase the resistance of the roof beam subassembly 100 on floor before the vehicle and change the ability, in the driving process, even the automobile body appears the shake because of reasons such as road surface, right seat installation roof beam 40 and left seat installation roof beam 30 can not appear warping yet, can effectively reduce the risk that the driving seat appears the shake or produces the abnormal sound on left seat installation roof beam 30 and right seat installation roof beam 40, be favorable to reducing the road noise in the driving process, be favorable to improving the seat mode, for example, improve the whole car mode of driving seat about 2Hz, and then improve user's use experience.

Moreover, the structural rigidity of the beam assembly 100 of the vehicle front floor can be enhanced by providing the connecting beam 50, so that the risk of structural damage to the beam assembly 100 due to cyclic load and the like can be reduced, the beam assembly 100 is prevented from being broken or damaged by fatigue, the problem of fatigue durability of the beam assembly 100 is effectively solved, and the operational reliability of the beam assembly 100 can be improved.

Meanwhile, a multi-section beam structure can be formed in the beam assembly 100 by arranging the connecting beams 50, the structural design is very simple, on one hand, the production and manufacturing cost can be effectively reduced, the assembly difficulty among the multi-section beams is reduced, and the structural stability of the beam assembly 100 of the vehicle front floor is strong; on the other hand, since the multi-sectional beam structure is formed, the operational reliability of the beam assembly 100 can be made stronger.

In addition, in some embodiments, as shown in fig. 2, the beam assembly 100 of the front floor of the vehicle is mounted to the front floor 10 of the vehicle, since a multi-section beam structure may be formed in the beam assembly 100, the overall structural rigidity of the beam assembly 100 and the front floor 10 may be effectively increased, occurrence of vibration of the front floor 10 during use of the vehicle body may be reduced, occurrence of shaking or deformation of the front floor 10 due to shaking or deformation of the left seat mounting beam 30 or the right seat mounting beam 40 may be avoided, further, a bending mode of the front floor 10 may be improved, bending rigidity of the front floor 10 may be improved, and risk of shaking of the front floor 10 and risk of fatigue endurance of the vehicle body during use may be reduced. In addition, the vibration of the lower vehicle body is reduced, and the fatigue endurance risk of the whole vehicle is reduced.

In some specific embodiments, the middle portion of the front floor 10 may be configured to form a first protrusion 11 extending in the front-rear direction, the center tunnel cover 20 may be configured to form a second protrusion 21, and after the center tunnel cover 20 is installed in place on the front floor 10, the first protrusion 11 and the second protrusion 21 are engaged, so that the center tunnel cover 20 can be installed in a fixed position, and the center tunnel cover 20 can be prevented from shaking.

The left and right seat mounting beams 30, 40 may extend in the left-right direction (i.e., the Y direction of the vehicle body), facilitating the mounting of the driver's seat. The connecting beam 50 may connect the left and right seat mounting beams 30, 40 by welding. Here, the left seat mounting beam 30 may be connected to the front floor 10 and the left side of the center tunnel cover 20 by welding, for example, a portion of the left seat mounting beam 30 is connected to the second protrusion 21 of the center tunnel cover 20. The right seat mounting beam 40 may be connected to the front floor 10, the right side of the center tunnel cover 20 by welding, for example, a portion of the right seat mounting beam 40 is connected to the second convex portion 21 of the center tunnel cover 20. It is thereby possible to realize the mounting of the beam assembly 100 of the vehicle front floor to the front floor 10.

Of course, left seat installation roof beam 30, right seat installation roof beam 40 also can be according to actual design demand and left right direction and be certain contained angle to form multistage beam structure through tie-beam 50, these are all within the utility model discloses a protection scope.

According to the utility model discloses beam assembly 100 on floor before vehicle connects left seat installation roof beam 30 and right seat installation roof beam 40 through tie-beam 50, can effectively promote beam assembly 100's structural rigidity, reduces the risk that shake or abnormal sound appear in driving in-process left seat installation roof beam 30 or right seat installation roof beam 40, and then reduces the way and makes an uproar, is favorable to improving the seat mode, improves the user and uses experience to be favorable to solving beam assembly 100's tired durable problem. In addition, the beam assembly 100 has a simple structure, which is beneficial to reducing the production cost and has high working reliability.

It should be noted that the embodiment of the present invention does not specifically limit the specific connection relationship between the connection beam 50 and the left and right seat mounting beams 30 and 40. In some embodiments of the present invention, as shown in fig. 2, the connecting beam 50, the left seat mounting beam 30, and the right seat mounting beam 40 may be engaged by overlapping. Specifically, the connection beam 50 may include a connection beam body 51, a first lap joint portion 52, and a second lap joint portion 53. Wherein the first overlapping portion 52 and the second overlapping portion 53 are respectively provided at the left and right ends of the beam body so as to be in overlapping engagement with the left and right seat mounting beams 30 and 40. The first overlapping portion 52 may be overlap-connected with the left seat mounting beam 30, and the second overlapping portion 53 may be overlap-connected with the right seat mounting beam 40, whereby a multi-sectional beam structure may be implemented.

Because the connecting beam 50, the left seat mounting beam 30 and the right seat mounting beam 40 form a multi-section beam structure through lap joint, on one hand, the connecting area between the connecting beam 50 and the left seat mounting beam 30 and the right seat mounting beam 40 can be effectively increased through the first lap joint part 52 and the second lap joint part 53, so that the connecting tightness and the connecting strength can be improved, and the influence on the connecting stability and the connecting reliability caused by stress concentration can be avoided; on the other hand, the thickness of the connecting area of the connecting beam 50, the left seat mounting beam 30 and the right seat mounting beam 40 can be increased, that is, the thickness of the partial area of the beam assembly 100 of the vehicle front floor is increased, so that the structural rigidity and the deformation resistance of the beam assembly 100 of the vehicle front floor can be improved, the stable state of the driving seat and the vehicle body in the driving process can be kept, the road noise can be reduced, and the use experience of a user can be improved.

In order to provide greater stability in the coupling engagement between the connecting beam 50 and the left and right seat mounting beams 30, 40, in some embodiments, the overlapping dimension of the first overlapping portion 52 and the left seat mounting beam 30 in the left-right direction may be greater than or equal to 5cm, for example, may be 5cm, 7cm, 9cm, 10cm, etc. Therefore, on one hand, the risk that the connecting beam 50 and the left seat mounting beam 30 cannot be stably connected due to the fact that the overlapping size is too small can be avoided; on the other hand, the phenomenon that the production cost is reduced due to the fact that the overlapping size is too large can be avoided, and the assembly difficulty and the overall weight are prevented from being improved.

And by controlling the overlapping size of the first overlapping portion 52 and the left seat mounting beam 30 within the above range, it is possible to reduce the production cost while achieving a stable coupling effect between the coupling beam 50 and the left seat mounting beam 30. Also, in some embodiments in which the main driving seat mounting point is provided on the left seat mounting beam 30, the overlapping size in the above range may allow the first overlapping portion 52 to cover the first driving seat mounting point, which is advantageous to improve the mounting stability of the driving seat.

Also, in some embodiments, the overlapping dimension of the second overlapping portion 53 with the right seat mounting beam 40 in the left-right direction may be greater than or equal to 5cm, for example, may be 5cm, 7cm, 8cm, 10cm, or the like. Therefore, on one hand, the risk that the connecting beam 50 and the right seat mounting beam 40 cannot be stably connected due to the fact that the overlapping size is too small can be avoided; on the other hand, the phenomenon that the production cost is reduced due to the fact that the overlapping size is too large can be avoided, and the assembly difficulty is avoided being improved.

And by controlling the overlapping size of the second overlapping portion 53 and the right seat installation beam 40 within the above range, it is possible to reduce the production cost while achieving a stable coupling effect between the connection beam 50 and the right seat installation beam 40. In some embodiments in which the passenger seat mounting point is provided on the right seat mounting beam 40, the overlapping dimension in the above range may allow the second overlapping portion 53 to cover the second passenger seat mounting point, which is beneficial to improving the mounting stability of the passenger seat.

In some embodiments, as shown in fig. 2, the connection beam body 51 may have a center line extending in the front-rear direction. In other words, the connecting beam body 51 may be configured as a symmetrical structure, which is beneficial to uniform stress and convenient for processing of the workpiece. Also, the first strap 52 and the second strap 53 may be symmetrically arranged about the midline, i.e., the distance between the first strap 52 and the midline is equal to the distance between the second strap 53 and the midline.

Therefore, when the beam assembly 100 shakes or shakes due to a torque or a load, since the connection area of the first bridging portion 52 and the left seat mounting beam 30 is the same as the connection area of the second bridging portion 53 and the right seat mounting beam 40, the first bridging portion 52 and the second bridging portion 53 are uniformly stressed, on one hand, fatigue damage caused by an excessive load applied to one of the first bridging portion 52 or the second bridging portion 53 can be avoided, and the service life of the first bridging portion 52 and the second bridging portion 53 can be prolonged; on the other hand, the production of the first bridging portion 52 and the second bridging portion 53 is facilitated, and the production cost is reduced.

In some specific embodiments, as shown in FIG. 2, the first strap 52 overlaps the left seat mounting beam 30 by 5cm, and the second strap 53 overlaps the right seat mounting beam 40 by 5cm. And the first overlapping portion 52 and the second overlapping portion 53 are symmetrical with respect to the center line of the connecting beam body 51, so that the first overlapping portion 52 and the second overlapping portion 53 are uniformly stressed while achieving a stable connecting effect of the connecting beam 50 and improving the rigidity of the beam assembly 100 of the vehicle front floor, and fatigue damage is prevented from occurring.

In some embodiments of the present invention, as shown in fig. 2, the width of the connecting beam 50, the width of the left seat mounting beam 30, and the width of the right seat mounting beam 40 are the same in the front-rear direction. Specifically, if the width of the connecting beam 50 is smaller than the width of the left seat mounting beam 30 and the right seat mounting beam 40, a gap may occur in the multi-sectional beam structure formed by the connecting beam 50, and thus the structural rigidity and the deformation resistance of the continuous multi-sectional beam may be reduced, and particularly, the portions of the left seat mounting beam 30 and the right seat mounting beam 40 that exceed the width of the connecting beam 50 may have a low structural strength and may be easily deformed. On the other hand, if the width of the connecting beam 50 is greater than the width of the left and right seat mounting beams 30 and 40, although the structural rigidity of the beam assembly 100 can be improved, the portion of the connecting beam 50 beyond the left and right seat mounting beams 30 and 40 may have a risk of structural interference, and may cause unnecessary material waste, increasing the overall weight and the difficulty of manufacturing.

In this embodiment, the widths of the three cross beams (i.e., the connecting beam 50, the left seat mounting beam 30, and the right seat mounting beam 40) are the same, which is beneficial to increase the contact area between the connecting beam 50 and the left seat mounting beam 30, and the right seat mounting beam 40 in the front-rear direction, so that the connecting effect of the connecting beam 50 is more stable and firm, the gap of the multi-section beam structure is avoided, and the structural rigidity of the beam assembly 100 can be effectively improved. And simultaneously, the difficulty of the finished piece is reduced, and the structural interference with other structures in the beam assembly 100 is avoided.

In order to improve the structural strength of the connecting beam 50, in some embodiments of the present invention, as shown in fig. 3, at least one reinforcing portion 54 may be disposed on the connecting beam 50, that is, one or more reinforcing portions 54 may be disposed on the connecting beam 50, which are all within the protection scope of the embodiments of the present invention. Through setting up rib 54, even tie-beam 50 receives great load, also can have good fracture resistance, avoids tie-beam 50 to appear breaking and influence tie-beam 50's connection effect, avoids influencing the structural rigidity of roof beam subassembly 100, is favorable to improving the steadiness of tie-beam 50 connection effect, and then avoids left seat installation roof beam 30 or right seat installation roof beam 40 to appear shaking or abnormal sound, improves the whole car mode of driving seat.

It should be noted that the embodiment of the present invention does not particularly limit the specific structure, arrangement position, and the like of the reinforcement portion 54. In some embodiments, as shown in fig. 3, the reinforcement portion 54 may be a reinforcement rib, and the reinforcement rib may extend in the left-right direction. Specifically, the structural strength of the connection beam 50 can be effectively improved by arranging the reinforcing ribs, and the connection beam 50 is prevented from being deformed greatly due to pressure, torsion or bending. For example, the reinforcing ribs may be raised strip-shaped structures on the connecting beam 50, so that the structural design of the reinforcing ribs is simple and the processing is convenient.

Also, since the left and right seat mounting beams 30 and 40 are provided on the left and right sides of the center tunnel cover 20, respectively, the connection beam 50 connects the left and right seat mounting beams 30 and 40, and the reinforcing bead extends in the left-right direction. The reinforcing bead may play a role of resisting breakage when the force applied to the connection beam 50 by the left seat mounting beam 30 or the right seat mounting beam 40 is in the left-right direction. When the seat mounting beam or the right seat mounting beam 40 applies a force to the connection beam 50 in the front-rear direction, the reinforcing bead may serve as a torsion resistance.

In some embodiments in which some of the coupling beams 50 include the coupling beam body 51, the first overlapping portion 52 and the second overlapping portion 53, the reinforcing rib may be disposed on the coupling beam body 51, or may be disposed on the first overlapping portion 52 or the second overlapping portion 53, and the embodiments of the present invention are not limited in particular.

In some specific embodiments, two reinforcing ribs are provided, and two reinforcing ribs are provided on the connecting beam body 51. And, two strengthen protruding muscle along left right direction extension, and mutual parallel arrangement, can make tie-beam 50 be close to the anti deformability roughly the same of front and back both ends region from this, avoid tie-beam 50 certain regional anti deformability not enough and appear fatigue damage.

In some embodiments of the present invention, as shown in fig. 3, the middle portion of the connecting beam 50 may be provided with a connecting portion 55, and the connecting portion 55 may be used to mount a sub instrument assembly of a vehicle. Specifically, if the connecting beam 50 is not provided, the sub-instrument assembly is directly mounted on the center tunnel cover plate 20, and there may be problems that the mounting rigidity of the sub-instrument assembly is insufficient, and abnormal sound occurs in the sub-instrument assembly. In this embodiment, the auxiliary instrument assembly can be mounted on the connecting beam 50 through the connecting portion 55, and the connecting beam 50 can serve as the mounting surface of the auxiliary instrument assembly, so that the mounting rigidity of the auxiliary instrument assembly can be effectively increased, the abnormal sound risk of later use of the auxiliary instrument assembly is reduced, and the use experience of a user is favorably improved.

It should be noted that the "middle portion" includes, but is not limited to, a middle position of the connection beam 50, and in some embodiments where the connection beam 50 includes the connection beam body 51, the "middle portion" may refer to any one of four corner positions of the connection beam body 51.

Furthermore, the embodiment of the present invention does not specially limit the concrete structure of the connection portion 55, and the connection portion 55 may be a bolt, or a screw, etc., and can both realize the installation effect of the sub-instrument assembly. In some specific embodiments, as shown in fig. 3, the connecting portion 55 is a bolt, four bolts may be disposed on the connecting beam body 51, and the four bolts are respectively located at four corners of the connecting beam body 51, so that the sub instrument assembly can be more stably mounted.

In some embodiments of the present invention, as shown in fig. 3, the middle portion of the connecting beam 50 may be provided with a through hole 56, on one hand, the through hole 56 may be a positioning hole of the sub-instrument assembly, or a mounting point of a fixing clip of the linear speed pipeline; on the other hand, the through-hole 56 also serves to reduce the weight of the bridge 50, which is advantageous for reducing the weight of the bridge 50.

In some embodiments where the connection beam 50 is provided with a reinforcing rib, the reinforcing rib extends in the left-right direction, and the through hole 56 may be formed in the middle of the reinforcing rib, so that the structural rigidity of the connection beam 50 is improved by the reinforcing rib, and the positioning and mounting effects of functional components such as the sub-instrument assembly and the like can be achieved by the through hole 56, or the weight of the connection beam 50 can be reduced.
