Description of the drawings
Some specific realities of the utility model are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter
Apply example.Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that
The drawings are not necessarily drawn to scale.In attached drawing：
Fig. 1 is the schematic diagram of back seat reinforcing structure for cross beams installation vehicle in front partial structurtes；
Fig. 2 is the schematic diagram of back seat reinforcing structure for cross beams installation rear vehicle partial structurtes；
Fig. 3 is the schematic diagram of reinforcement structure shown in Fig. 2.
Specific implementation mode
Fig. 1 is the schematic diagram of back seat reinforcing structure for cross beams installation vehicle in front partial structurtes.As shown in Figure 1, vehicle
Threshold internal plate 3 in partial structurtes is arranged in parallel with left rear longitudinal beam 2, back seat crossbeam 4 be perpendicularly fixed at threshold internal plate 3 with it is left
At floor side member 2, one end of crossbeam 4 is connected at threshold internal plate 3, the side collision shown in arrow direction in vehicle occurs such as figure
When, crossbeam 4 is used to support body construction, prevents threshold internal plate 3 from deforming.
As what domestic collision safety required steps up, 2018 editions C-NCAP side impacts require also corresponding promotion, side impact platform
Vehicle quality 950kg is promoted to 1400kg, and side collision moves 250mm behind position, and requirements at the higher level are proposed for vehicle side collision.
It is found through experiment that the vehicle partial structurtes for meeting 2015 editions C-NCAP side impact requirements in the prior art can no longer meet 2018
Version C-NCAP side impacts requirement.Concrete reason is that the impact load caused by the side impact is excessive, and crossbeam 4 can be made to 2 side of left rear longitudinal beam
To bending, after crossbeam 4 is bent, threshold internal plate 3, which loses, will produce mobile and deformation after crossbeam 4 supports, cannot be to rear door
It is effectively supported, rear door increases the danger of passenger inside the vehicle after deforming upon.In view of the above-mentioned problems, applicant is in above-mentioned vehicle
It is improved at partial structurtes, to meet new side impact requirement.
Fig. 2 is the schematic diagram of back seat reinforcing structure for cross beams installation rear vehicle partial structurtes.As shown in Fig. 2,
Increase a back seat reinforcing structure for cross beams in vehicle partial structurtes.It is due to 4 both sides unbalance stress of crossbeam that bending, which occurs, for crossbeam 4
Cause, structure as shown in Figure 2 is it is found that crossbeam 4 is larger close to the side stress of left rear longitudinal beam 2, when the load that the side is subject to is super
It when crossing the maximum, force that crossbeam 4 can bear in itself, i.e., can bend, crossbeam 4 is bent in order to prevent, it should reduce the side
The stress of crossbeam 4, accordingly, it is considered to the reinforced structure for installation 1 between the side left rear longitudinal beam 2 and threshold internal plate 3.
Fig. 3 is the schematic diagram of reinforcement structure 1 shown in Fig. 2.As shown in figure 3, reinforcement structure 1 includes 11 He of vertical panel
Two side plates, wherein vertical panel 11 is the platy structure of a quadrangle, and two side plates are from the opposite both ends of vertical panel 11 to extension
It stretches and is bent to the same side, be respectively designated as the first side plate 121 and the second side plate 122.First side plate 121 is fixed on left back
Longeron 2 is fixed on threshold internal plate 3 close to the side of left rear longitudinal beam 2 close to the side of threshold internal plate 3, the second side plate 122.Work as reinforcement
When structure 1 is made for metal material, reinforcement structure 1 can be fixed by welding.When reinforcement structure 1 is non-metallic material
When material, reinforcement structure 1 can be fixed by way of gluing.After reinforcement structure 1 fixes, it is configured to will be in threshold
The local collision load transmission that plate 3 is subject to is to left rear longitudinal beam 2, to reduce the stress of crossbeam.Reinforcement structure 1 is fixed to left rear longitudinal beam
Between 2 and threshold internal plate 3, with crossbeam shape at double-layer structure, impact load is transferred to left rear longitudinal beam 2, avoids threshold internal plate 3 only
From stress, the stress of crossbeam is reduced, improves vehicle body side rigidity, to ensure car body stabilization in side collision, reduces side
Face collision intrusion speed and side intrusion volume, reinforces the effective protection to occupant in collision, reduces occupant and comes to harm risk, carries
High vehicle security energy.
As shown in figure 3, in another embodiment of the utility model, reinforcement structure 1 further include by vertical panel 11 with
Third side plate 123 and the 4th side plate 124 made of the adjacent both ends of side plate 121 extend outwardly and bent to the same side, the 4th
Side plate 124 is fixed on rear floor 5.Four side plates are fixed in the same side of vertical panel 11, the 4th side plate 124 of reinforcement structure 1
Onto rear floor 5, it in local collision load transmission to rear floor 5, can will be further ensured that car body is stablized in side collision
Deformation reduces side collision intrusion speed and side intrusion volume.
In order to prevent crossbeam hair at bending to greatest extent, vertical panel 11 is arranged in parallel with back seat crossbeam.Work as vertical panel
11 with crossbeam be arranged in parallel when, larger folding force can be born.
As shown in figure 3, parting mouth is equipped between two neighboring side plate, so that two neighboring side plate is relatively independent.Parting
Mouth could be provided as circle.The setting of parting mouth can be to avoid 1 stamping cracking of reinforcement structure.
Further include at least one reinforcing rib 13 with reference to figure 3, on vertical panel 11, one end of reinforcing rib 13 is close to the first side plate
121, the opposite other end is close to the second side plate 122.Since the length direction (direction shown in Fig. 3 arrows) of reinforcing rib 13 is with after
The axial direction (direction shown in Fig. 2 arrows) of seat beam is parallel, can further increase the force transfer capacity of reinforcement structure 1.?
In one embodiment, reinforcing rib 13 can be convexed to form from part vertical panel 11 to the side far from side plate.Using such knot
The reinforcing rib 13 of structure, while enhancing 1 force transfer capacity of reinforcement structure, moreover it is possible to reduce weight.In other realities of the utility model
It applies in example, reinforcing rib 13 can also be a strip structure, be fixed on vertical panel 11.The reinforcing rib 13 of strip structure can be one
The product of section reinforcing bar or one section of other materials.Reinforcing rib 13 can be fixed to by way of welding or gluing on vertical panel 11.
In another embodiment of the utility model, in order to realize vehicle lightweight, pollution is reduced, vertical panel 11 is equipped with
Lightening hole 14.It is simulated by software, the region of stress minimum is found in reinforcement structure 1, by its borehole or reduce the region
Weight, to achieve the purpose that loss of weight.
For the ease of installation, vertical panel 11 is equipped with fabrication hole 15, and fabrication hole 15 can be location hole.
The reinforcement structure 1 can integrated punch forming, manufacturing process is simple, and production efficiency is high, and production cost is low.
So far, although those skilled in the art will appreciate that the more of the utility model have been shown and described in detail herein
A exemplary embodiment still, still can be according to the utility model public affairs in the case where not departing from the spirit and scope of the utility model
The content opened directly determines or derives many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
The range of type is understood that and regards as to cover other all these variations or modifications.
