Direction is rolled over close to side-wall outer-plate 105, and formed angle beta is obtuse angle between the second bending part 109 and second connecting portion 108.
Since second connecting portion 108 is connect with first connecting portion 106 by connector, such mode can enhance；B column
The bonding strength of inner panel 104 under upper inner panel 103 and B column, further enhances the Z-direction support strength of B column.
In addition, formed angle beta is obtuse angle between the second bending part 109 and second connecting portion 108, guarantee B column upper space
Less than B column lower space, the Z-direction support strength of B column is further enhanced, the deflection on B column top is efficiently reduced, thus
The chest of driver and passenger and the extent of damage on head are effectively alleviated, keeps car body not to be curved to the inside to the maximum extent, makes
Interior space is sufficiently large, to guarantee the safety of driver and passenger.
Further, in certain embodiments, the outer surface of the inner surface of first connecting portion 106 and second connecting portion 108
It fits.
By the way that the inner surface of first connecting portion 106 and the outer surface of second connecting portion 108 are fitted, such mode energy
Enough guarantee that first connecting portion 106 is closely joined together with second connecting portion 108, further enhances B column overall stiffness.
It further, in certain embodiments, further include securing plate 110, securing plate 110 is interior with second connecting portion 108
Surface fits.
By the way that securing plate 110 is arranged, first connecting portion 106 can be further enhanced and the connection of second connecting portion 108 is strong
Degree, to further enhance B column overall stiffness.
Further, in certain embodiments, securing plate 110 is provided with limit sleeve 111, and connector is arranged in limit sleeve
In 111.
By the way that limit sleeve 111 is arranged, position-limiting action can be played to connector, guarantees the length direction of connector as far as possible
It is vertical with the plate face of first connecting portion 106, it prevents connector from deviateing, improves connectivity robustness.
Optionally, the both ends bending of securing plate 110, forms reinforcing rib.
Further, in certain embodiments, connector is bolt 112.
Optionally, first connecting portion 106 and second connecting portion 108 are provided with through-hole, and limit sleeve 111 is provided with internal screw thread.
