It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.

Fig. 2 is a schematic structural view of a B-pillar according to some embodiments of the present application, fig. 3 is an enlarged view of a portion a in fig. 2, fig. 4 is a schematic view of B-B in fig. 3, fig. 5 is a schematic view of C-C in fig. 3, fig. 6 is a schematic view of D-D in fig. 3, and fig. 7 is a schematic structural view of a B-pillar and a back door weather strip joint according to some embodiments of the present application.

Referring to fig. 2-7, a B-pillar 1 is provided in the embodiment of the present application, where the B-pillar 1 includes a body portion 2 and a leveling portion 3. The body portion 2 includes a first smooth region 21, a recessed region 22, and a second smooth region 23 arranged in this order along the first direction X, and an avoidance space 5 is formed between the recessed region 22 and the rear door weather strip joint 4. The leveling part 3 includes a first protruding strip 31 and a second protruding strip 32, where the first protruding strip 31 and the second protruding strip 32 are disposed in the recessed area 22 along the second direction Y and located on two opposite sides of the avoiding space 5 in the second direction Y. Opposite ends of the first protruding strip 31 are connected to the first smooth area 21 and the second smooth area 23 in a one-to-one correspondence, and opposite ends of the second protruding strip 32 are connected to the first smooth area 21 and the second smooth area 23 in a one-to-one correspondence. The first protruding strip 31 includes a first complementary plane 311 opposite to the concave region 22, and the second protruding strip 32 includes a second complementary plane 321 opposite to the concave region 22, where the first complementary plane 311, the second complementary plane 321, the first smooth region 21, and the second smooth region 23 are coplanar. Wherein the second direction Y intersects the first direction X.

Because the outer surfaces of the first smoothing region 21 and the second smoothing region 23 may be curved surfaces, the coplanarity of the first complementary plane 311, the second complementary plane 321, the first smoothing region 21, and the second smoothing region 23 in the embodiments of the present application refers to the smooth transition at the junction between the first complementary plane 311 and the first smoothing region 21, and the junction between the second complementary plane 321 and the first smoothing region 21, and the junction between the second smoothing region 23; it is not represented that the first smoothing region 21, the second smoothing region 23, the first complementary plane 311 and the second complementary plane 321 are on the same plane, nor that the first complementary plane 311 and the second complementary plane 321 are planes.

The first complementary plane 311 and the second complementary plane 321 in the embodiment of the present application may be a plane, a curved surface, or an irregularly shaped plane combining a plane and a curved surface.

Optionally, the first direction X is perpendicular to the second direction Y.

The first ridge 31 and the second ridge 32 of the embodiment of the present application are stripe-shaped structures. The B-pillar 1 of the present embodiment is provided with the first protruding strip 31 and the second protruding strip 32 in the concave region 22, and the surface of the first protruding strip 31, the second protruding strip 32 opposite to the concave region 22 is coplanar with the first smooth region 21 and the second smooth region 23, and the first protruding strip 31 and the second protruding strip 32 are protruding relative to the concave region 22, so that the B-pillar 1 presents a smoother look and feel than before, and has a good visual effect and is more attractive. Further, since the first ridge 31 and the second ridge 32 are provided on opposite sides of the escape space 5 in the second direction Y, the recess 22 is not affected from escaping the rear door weather strip joint 4.

The forming rebound of the part refers to the phenomenon that the shape of the part is partially recovered after the load is removed in the process of stamping forming, so that the shape and the size of the part are not matched with those of the surface of a die. The first raised strips 31 and the second raised strips 32 are arranged in the concave area 22, namely the mass and the volume of the B column 1 at the position are increased, and the forming rebound degree and the baking deformation degree of the B column 1 are reduced. In addition, the first raised strips 31 and the second raised strips 32 partially shield the concave region 22, so that the surface pit, uneven light and shadow and other surface problems of the concave region 22 can be covered, and the aesthetic property of the B column 1 is improved.

The rigidity of a part refers to the ability of the part to resist deformation. NVH refers to noise, vibration and harshness. The rigidity of the part can affect the NVH problem of the vehicle. Generally, the lower the rigidity, the more serious the NVH problem of the vehicle. The first raised strips 31 and the second raised strips 32 are arranged in the concave area 22, so that the structural strength and rigidity of the B-pillar 1 at the position can be increased, and the NVH problem of the vehicle can be relieved.

Optionally, the first complementary surface 311 and the second complementary surface 321 each include a curved surface portion, and the curved surface portion is curved toward a side facing away from the recess 22. Therefore, the lines presented by the B column 1 are plump and attractive.

In some embodiments, the first raised strips 31 and the second raised strips 32 are disposed at two opposite edges of the recessed area 22 in the second direction Y. Namely, the first ridge 31 and the second ridge 32 extend along opposite edges of the recessed region 22 in the second direction Y.

The first raised strips 31 and the second raised strips 32 are arranged at two opposite edges of the concave area 22 in the second direction Y, so that the rear door sealing strip joint 4 is avoided to the greatest extent, and the rear door sealing strip joint is attractive.

In some embodiments, on a path extending from the center of the concave region 22 along the first direction X to the first and second

smooth regions

21 and 23, the concave depth of the concave region 22 gradually decreases, and the convex heights of the first and second

convex strips

31 and 32 relative to the concave region 22 gradually decrease.

The center of the depressed region 22 refers to the middle position of the depressed region 22 in the longitudinal direction. The center of the concave region 22 is the position with the largest concave depth, and the concave depth of the concave region 22 gradually decreases from the center of the concave region 22 to the junction of the concave region 22 with the first smooth region 21 and the second smooth region 22. In order to make the first protrusion 31 and the second protrusion 32 coplanar with the first smooth area 21 and the second smooth area 23, the protrusion heights of the first protrusion 31 and the second protrusion 32 with respect to the concave area 22 are also gradually reduced from the above direction.

The recess depth of the recess area 22 gradually decreases from the center to the two sides, and the center of the recess area 22 is opposite to the rear door sealing strip joint 4 so as to avoid the rear door sealing strip joint, so that the recess depth is the largest. The concave depth gradually decreases to two sides, so that smooth transition and attractive bending can be realized while avoiding.

In some embodiments, the portions of the first protrusions 31 opposite to the second protrusions 32 in the second direction Y are equal in height.

The different positions of the first raised strips 31 are different from the raised heights of the recessed areas 22, and the same applies to the different positions of the second raised strips 32 from the raised heights of the recessed areas 22, so that the raised heights of the first raised strips 31 and the second raised strips 32 in the second direction Y are equal to each other, thereby facilitating processing and manufacturing, and providing a better sense of sight to the user due to the symmetrical sense in height.

In some embodiments, the first ridge 31, the second ridge 32, and the recessed region 22 are integrally formed. The integrated forming mode is convenient to process and manufacture, and can not fall off.

In some embodiments, the first protrusion 31 is located at an edge of the body 2 near the front door of the vehicle, and the second protrusion 32 is located at an edge of the body 2 near the rear door of the vehicle, and the slope of the first protrusion 31 is smaller than the slope of the second protrusion 32.

The slope of the present embodiment refers to the degree of inclination of the first ridge 31 and the second ridge 32 with respect to the horizontal plane, and the first ridge 31 and the second ridge 32 are straight structures.

The slope of the first protruding strip 31 is smaller than the slope of the second protruding strip 32, so that the B-pillar 1 can be matched with the trend of the front and rear doors of the vehicle in appearance, and the aesthetic feeling is improved.

In some embodiments, the distance between the first convex strip 31 and the second convex strip 32 gradually increases from the first smooth region 21 to the second smooth region 23.

The distance between the first raised strips 31 and the second raised strips 32 from the upper part to the lower part of the vehicle gradually increases, that is, the size of the concave area 22 in the second direction Y gradually increases from the upper part to the lower part of the vehicle, so as to meet the structural requirement of the vehicle body.

In some embodiments, the distance between the first ridge 31 and the second ridge 32 ranges from 8-30mm.

Further, the distance between the first ridge 31 and the second ridge 32 is in the range of 20-25mm.

The inventors found that when the distance between the first ridge 31 and the second ridge 32 is smaller than 8mm, the dimension of the B-pillar 1 in the second direction Y is smaller here, and it is difficult to satisfy the structural strength requirement. When the distance between the first ridge 31 and the second ridge 32 is greater than 30mm, this results in a larger dimension of the B pillar 1 in the second direction Y, and a smaller dimension of the front and rear doors. In view of this, the inventor sets the distance between the first ridge 31 and the second ridge 32 to be 8-30mm so that the dimensions of the first ridge 31 and the second ridge 32 can satisfy the structural requirements without affecting the arrangement of the front and rear doors of the vehicle.

In some embodiments, the length of the first and

second ribs

31, 32 ranges from 80-150mm.

Further, the length of the first ridge 31 and the second ridge 32 ranges from 120mm to 140mm.

The inventor has found that when the lengths of the first raised strips 31 and the second raised strips 32 are less than 80mm, that is, the dimensions of the recessed area 22 in the first direction X are less than 80mm, since the recessed area 22 is not only required to form an avoidance space with the rear door weather strip joint 4, but also is required to be smoothly connected with the first smooth area 21 and the second smooth area 23, the smaller dimensions in the first direction X may result in a larger bending degree of the recessed area 22, and the larger heights of the protrusions of the first raised strips 31 and the second raised strips 32 may result in a poorer visual appearance for the user. When the lengths of the first raised strips 31 and the second raised strips 32 are greater than 150mm, the size of the recessed area 22 along the first direction X is larger, which affects the arrangement of other structures of the B-pillar 1.

In view of this, the inventors set the length ranges of the first ridge 31 and the second ridge 32 to 80-150mm, and improve the aesthetic properties without affecting other structural arrangements.

The first display layer and the second display layer of the present embodiment adopt a structure different from the appearance of the first ridge 31 and the second ridge 32, so as to emphasize the first ridge 31 and the second ridge 32. By providing the first display layer and the second display layer, smooth appearance brought by the first raised strips 31 and the second raised strips 32 can be emphasized, and novel visual experience can be brought to the user.

The first display layer of the present embodiment may be a material different from the color of the first raised line 31, and the second display layer may be a material different from the color of the second raised line 32. For example, when the first and

second protrusions

31 and 32 are black in color, the first and second display layers may be coated silver layers. The first display layer and the second display layer may be made of a material having a light reflection effect stronger than that of the first convex strip 31 and the second convex strip 32.

The embodiment of the application also provides a vehicle, which comprises the vehicle B column 1.
