Detailed description of the invention
Being described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings.The embodiment described below with reference to accompanying drawing is illustrative of, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.
Below with reference to the accompanying drawings longeron 100 according to this utility model embodiment is described in detail, and longeron 100 can be applied on vehicle.
As depicted in figs. 1 and 2, may include that upper plate 10, lower plate 20 and middle reinforcement structure 30, upper plate 10 and the fixing connection of lower plate 20 according to the longeron 100 of this utility model embodiment, and between upper plate 10 and lower plate 20, limit cavity 40.Wherein, alternatively, upper plate 10 and lower plate 20 can adopt the mode being welded to connect to fix.Middle reinforcement structure 30 is arranged in cavity 40, and middle reinforcement structure 30 has for fixing the upper connecting portion 31 being connected with upper plate 10 and for the lower connecting portion 32 that be connected fixing with lower plate 20.Thus, middle reinforcement structure 30 is possible not only to strengthen the intensity of upper plate 10 and lower plate 20, the intensity of self can also be strengthened, when vehicle is collided, upper plate 10 and lower plate 20 all can be supplied to the support force that middle reinforcement structure 30 is certain, thus the deformation of middle reinforcement structure 30 can be reduced at least to a certain extent, and then the bending resistance of middle reinforcement structure 30 can be improved, improve the security performance of vehicle.Wherein, alternatively, upper connecting portion 31 can adopt two guarantor's solid weldings to be surely connected with upper plate 10, and lower connecting portion 32 can adopt with lower plate 20 that spot welding is fixing to be connected, such that it is able at least to a certain degree upper structural strength improving longeron 100, the security performance of raising vehicle.
According to an embodiment of the present utility model, middle reinforcement structure 30 be configured to domes 33 at least partially.As shown in Figure 4, domes 33 can be substantially curved, and domes 33 can connect connecting portion 31 and lower connecting portion 32 preferably, so that middle reinforcement structure 30 intensity is better, it is also possible to strengthen the intensity of upper plate 10 and lower plate 20 further.
Specifically, as shown in Figure 2 and Figure 4, domes 33 can bend towards upper plate 10, and the apex portion 34 of domes 33 is fixing with upper plate 10 to constitute upper connecting portion 31.Thus, upper connecting portion 31 is arranged on the apex portion 34 of domes 33, such that it is able to strengthen the bonding strength of upper connecting portion 31 and upper plate 10 at least to a certain extent, improves the bending resistance of longeron 100, improves the security performance of vehicle.
Alternatively, lower connecting portion 32 is connected to the front-end and back-end of domes 33.In other words, lower connecting portion 32 can be two, one of them lower connecting portion 32 is arranged on the front end of domes 33, another lower connecting portion 32 is arranged on the rear end of domes 33, and the apex portion 34 of domes 33 constitutes upper connecting portion 31, such that it is able to the reinforcement structure 30 booster action to longeron 100 in the middle of promoting further, improve the bending resistance of longeron 100.
According to a preferred embodiment of the present utility model, upper plate 10 may include that the upper plate sloping portion 11 and upper plate straight portion 12 that are connected to each other, lower plate 20 may include that the lower plate sloping portion 21 and lower plate straight portion 22 that are connected to each other, lower plate sloping portion 21 is positioned opposite with upper plate sloping portion 11, and lower plate straight portion 22 is positioned opposite with upper plate straight portion 12.The apex portion 34 of domes 33 is fixed with the intersection of upper plate sloping portion 11 and upper plate straight portion 12.Thus, it is natural that the front part being positioned at apex portion 34 of domes 33 can be connected transition with upper plate straight portion 12, it is natural that the rear section being positioned at apex portion 34 of domes 33 can be connected transition with upper plate sloping portion 11, thus the intensity of the intersection of upper plate sloping portion 11 and upper plate straight portion 12 can effectively be strengthened by domes 33, and then the structural strength of longeron 100 can be promoted, improve the security performance of vehicle.
Alternatively, as shown in Figure 2 and Figure 4, lower connecting portion 32 can be two, is positioned at the lower connecting portion 32 of above and fixes with lower plate sloping portion 21, is positioned at the lower connecting portion 32 of below and fixes with lower plate straight portion 22.Thus, by rationally arranging the fixing link position of two lower connecting portions 32 and lower plate 20, it is possible to make middle reinforcement structure 30 effectively strengthen the structural strength of lower plate 20, and then the intensity of longeron 100, the security performance of raising vehicle can be improved.
Alternatively, as it is shown on figure 3, longeron 100 can also include: side connecting plate 35, side connecting plate 35 is fixed with domes 33 and lower plate 20 respectively.By arranging side connecting plate 35, the bonding strength of domes 33 and lower plate 20 can be strengthened at least to a certain extent, but also the bonding strength between lower plate 20 and upper plate 10 can be strengthened by side connecting plate 35 and domes 33, such that it is able to strengthen the structural strength of longeron 100, improve the security performance of vehicle.Specifically, as it is shown on figure 3, domes 33 are it is so structured that arch sheet, side connecting plate 35 is fixed on the both sides of arch sheet symmetrically.
Preferably, as it is shown in figure 5, longeron 100 can also include: reinforcement structure 36, reinforcement structure 36 is arranged in middle reinforcement structure 30, and reinforcement structure 36 can extend along the bearing of trend of middle reinforcement structure 30.Wherein, reinforcement structure 36 can be reinforcement, and reinforcement can be multiple, such as, as it is shown in figure 5, reinforcement can be two, one of them reinforcement is integrally provided on the lower connecting portion 32 being positioned at rear side, and another reinforcement extends to domes 33 from the lower connecting portion 32 being positioned at front side.By arranging reinforcement structure 36, it is possible to the structural strength of reinforcement structure 30 in the middle of effectively strengthening, such that it is able to strengthen the overall construction intensity of longeron 100.
Longeron 100 according to this utility model embodiment, by arranging in middle reinforcement structure 30 and the fixing upper connecting portion 31 being connected of upper plate 10 and the lower connecting portion 32 that be connected fixing with lower plate 20, can so that the self-strength of middle reinforcement structure 30 be better, it is also possible that the structural strength of longeron 100 is better, so that the bending resistance of longeron 100 is strong, it is possible to the security performance making vehicle is good.And, by arranging middle reinforcement structure 30, it is possible to simplify the structure of longeron 100 at least to a certain extent so that longeron 100 lightweight.
Vehicle according to this utility model embodiment; longeron 100 including above-described embodiment; owing to being provided with middle reinforcement structure 30 in the longeron 100 of above-described embodiment, so that the security performance of vehicle is good, the passenger safety in vehicle can be protected at least to a certain extent.
