Example 1
At present, with the development of times and the progress of science and technology, the number of new energy automobiles is more and more nowadays, and the new energy automobiles have the characteristics of saving fuel energy, reducing exhaust emission and protecting the environment, and have good development prospects.
Compared with the traditional automobile, the new energy automobile has the great difference that the new energy automobile needs to carry the battery pack with the weight of 500 KG and 600KG, so that the automobile weight of the new energy automobile is greatly increased, the corresponding safety performance requirement on the automobile body of the new energy automobile can be higher, and in addition to the new law requirement of the middle and old research, the structural design of the traditional automobile can not meet the automobile body performance requirement of the new energy automobile in a new situation.
The B column of the automobile is a column between front and rear doors of the automobile and is used for buffering the impact on the side surface and the top of the automobile and protecting the safety of a driver and passengers. Because there is not external member and tie point in the middle of the B post top cavity in traditional structural design, and then with traditional car B post structural design application to new energy automobile, be difficult to solve when new energy automobile side bumps and/or roof pressure, the technical problem that B post upper end top cap boundary beam inner panel ftractures and regional solder joint tears.
In order to solve the above technical problems, the present invention provides a B-pillar structure for a vehicle body and a vehicle, fig. 1 is a schematic side view of a reinforcing plate of a B-pillar after connection according to the present invention; FIG. 2 is a schematic view of one side of the inner panel of the B-pillar after the connection according to the present invention; FIGS. 3 and 4 are cross-sectional views of the bolted joint of the present invention; fig. 5 and 6 are views illustrating a bolt and nut coupling process according to the present invention.
As shown in fig. 1 to 6, the present invention provides a B-pillar structure for a vehicle body, the vehicle body including: roof boundary beam inner panel 3, the B post structure includes: a B-pillar reinforcement plate 2;
the B column structure further comprises a sleeve 5, a connecting piece is arranged in the middle of the sleeve 5, and the sleeve 5 is fixedly connected with the top cover edge beam inner plate 3 and the B column reinforcing plate 2.
The B-pillar structure for the vehicle body and the vehicle solve the technical problems that when a new energy automobile is laterally collided or jacked, the roof side beam inner plate 3 at the upper end of the B-pillar is cracked and the welding spots in the area are torn;
in addition, the B column has simple structure and flexible and convenient installation, and greatly improves the performance of the vehicle body during side impact and top pressure.
Furthermore, the connecting piece penetrates through the sleeve 5 and is movably connected with the top cover edge beam inner plate 3 and the B column reinforcing plate 2.
Further, the connector includes: a bolt 1 and a nut 4;
the bolt 1 penetrates through the sleeve 5 along one side of the B-column reinforcing plate 2, and is in threaded connection with the nut 4 on one side of the roof side beam inner plate 3.
The reason for adding the sleeve 5 in the cavity is: because the cavity is hollow, direct bolting can be deformed because the plate is not supported, so that the dimensional tolerance of the assembly of the bolted rear side wall is difficult to control, and the cavity is connected with the bolt, so that the torque of the bolt is attenuated after the bolt runs for a long time, and the performance failure of safety requirements or the NVH problems such as abnormal sound are caused.
Further, the B-pillar structure for a vehicle body further includes: a B-pillar inner panel 8;
the B-pillar inner plate 8 is fixedly connected with the sleeve 5.
Further, the design clearance between the sleeve 5 and the B-pillar reinforcing plate 2 is in the range of 0.5-1.5mm,
preferably, the design clearance between the sleeve 5 and the B-pillar reinforcing plate 2 is 1 mm;
further, the B-pillar structure further includes: a roof side rail reinforcing plate 6;
the top cover edge beam reinforcing plate 6 is covered on the outer sides of the top cover edge beam inner plate 3 and the B column inner plate 8 and is fixedly connected with the top cover edge beam inner plate 3 and the B column inner plate 8,
a B-column cavity is formed, the sleeve 5 is arranged in the B-column cavity, and the structural strength of the cavity is improved by adding the sleeve 5 and the connecting piece, so that the defect that the structural cavity in the traditional structural design has no connecting piece is overcome;
and, through increasing a bolted connection in the middle of B post top cavity, make the weight that increases reduce, with low costs, connect easy operation.
Preferably, the cavity of the B column is of a polygonal structure, in particular a rectangular structure.
Preferably, the roof side rail reinforcing plate 6 is in a T-shaped structure.
Since the design clearance between the sleeve 5 and the B-pillar reinforcement plate 2 is in the interval of 0.5-1.5mm,
and then avoided manufacturing tolerance to cause the B post reinforcing plate 2 of sleeve 5 ejecting when B post reinforcing plate 2 closes with B post inner panel 8 to piece together, lead to the B post reinforcing plate 2 to push the problem emergence not in place.
Preferably, when side impact occurs:
the roof side rail inner plate 3 can be pushed to the vehicle interior direction by the B-pillar reinforcing plate 2, and when the stress is overlarge, the roof side rail inner plate 3 has a cracking tendency or is torn from the welding spot;
after the bolt connection is added, when the top cover boundary beam inner plate 3 is pushed towards the interior of the vehicle, the bolt connection structure can pull the top cover boundary beam inner plate 3 and the B column reinforcing plate 2 together, the stress of spot welding at a 7-circle corner of a door opening is greatly reduced, and the technical problem of cracking of the top cover boundary beam inner plate 3 is further solved.
Preferably, when pressing occurs:
the B column bears huge stress at the corner 7 of the door opening, and because the constraint point of the cavity frame is mainly the welding point of the door opening area at the edge of the frame, when the stress exceeds the strength of the welding point, the welding point between the B column reinforcing plate 2 and the B column inner plate 8 can be torn at the area close to the corner 7 of the door opening.
When the cavity is pressed by top pressure, welding spots between the B column inner plate 8 and the B column reinforcing plate 2 tend to be prone to collapse, the bolt is additionally connected in the middle of the cavity, the bolt pulls the B column inner plate 8 and the B column reinforcing plate 2 which tend to collapse from the middle of the cavity, the surfaces of the B column inner plate 8 and the B column reinforcing plate 2 in the middle of the cavity are simultaneously pulled, the whole cavity tends to be a whole, the condition that the cavity is connected only at the edge of a door opening originally is improved, and stress borne by other welding spots on the periphery is reduced.
The connection of the bolts effectively reduces the stress borne by welding spots in the door opening area of the B column, reduces the occurrence of stress concentration, and effectively solves the problem that the welding spots pressed on the top area of the B column are torn.
In addition, compared with a spot welding connection structure of the traditional structure, which is only arranged at the edge of the cavity, the connection structure directly increases the powerful bolt connection in the middle of the cavity, when the cavity is pressed, the bolt can effectively and greatly increase the load of the cavity which can be borne in the Y direction, and further effectively reduce the stress borne by other welding points.
In another aspect, the present invention provides a vehicle including the B-pillar structure for a vehicle body of any one of the above.
