In other embodiments, the locking member 11 can also be arranged on the lower interior panel 2, and the snap-on buckle 21 can be arranged on the upper interior panel 1.

[0025] Continue reading Figure 2 The locking member 11 includes a locking hole 111, a limiting protrusion 112 and a limiting plate 113. Specifically, the locking hole 111 passes through the lower interior panel 2 along the second direction Y. The limiting protrusion 112 and the limiting plate 113 are arranged at the edge of the locking hole 111, and the limiting protrusion 112 and the limiting plate 113 are arranged at intervals in the extension direction of the locking hole 111 (i.e., the second direction Y); the limiting protrusion 112 is provided with a first limiting surface 112a and a second limiting surface 112b intersecting each other; the limiting plate 113 extends along the extension direction of the locking hole 111 and A stop portion (not marked) is formed; the inner wall of the snap-in hole 111 includes a third limiting surface 111a and a fourth limiting surface 111b which are relatively arranged in the first direction Z; wherein the first limiting surface 112a and the end surface 113a of the stop portion are relatively arranged in the second direction Y, and the second limiting surface 112b and the first inner side surface 113b of the stop portion facing the inner side of the snap-in hole 111 are relatively arranged in the third direction X, and the first limiting surface 112a and the second limiting surface 112b both intersect with the third limiting surface 111a and the fourth limiting surface 111b.

[0026] Continue reading Figure 3The snap-fit ​​buckle 21 includes a first limiting step 214 and a second limiting step 215 protruding to opposite sides in the second direction Y.

[0027] The upper interior panel 1 in this embodiment can be assembled with the lower interior panel 2 along the second direction Y. When the upper interior panel 1 approaches the lower interior panel 2 along the second direction Y, the snap buckle 21 is gradually inserted into the snap hole 111 to achieve snap connection. After the snap connection is completed, the snap buckle 21 and the locking member 11 are positioned in three directions; wherein, in the first direction Z, the third limiting surface 111a and the fourth limiting surface 111b of the snap hole 111 respectively stop the upper surface and the lower surface of the snap buckle 21, thereby limiting the relative displacement of the upper interior panel 1 and the lower interior panel 2 in the first direction Z; in the second direction Y, the first limiting surface 112a and the end surface 113a of the stopping portion of the limiting plate 113 respectively stop the first limiting step 214 and the second limiting step 215, thereby limiting the relative displacement of the upper interior panel 1 and the lower interior panel 2 in the second direction Y; in the third direction X, the second limiting surface 112b and the first inner side surface 113b of the limiting plate 113 respectively stop the first limiting step 214 and the second limiting step 215, thereby limiting the relative displacement of the upper interior panel 1 and the lower interior panel 2 in the third direction X. The present application completes the positioning of the upper interior panel 1 and the lower interior panel 2 in three directions by setting a set of snap-fit ​​components, reduces the number of snap-fit ​​components while ensuring the accuracy of assembly positioning, ensures that the force on the automobile B-pillar 10 is uniform, and reduces the deformation and damage probability of the automobile B-pillar 10 during installation and removal. The outer surfaces of the upper interior panel 1 and the lower interior panel 2 in the automobile B-pillar 10 of the present application are flush, ensuring the appearance.

[0028] Optionally, continue to Figure 3The snap-fit ​​buckle 21 further includes a snap-fit ​​portion 211, and the snap-fit ​​portion 211 further includes a first side surface 211a and a second side surface 211b disposed opposite to each other along the second direction Y, and the first side surface 211a and the second side surface 211b are both connected to the snap-fit ​​end and the connection end. Optionally, the snap-fit ​​portion 211 is in a "J" shape, including two snap-fit ​​plates (not marked) and a connecting plate (not marked) connecting the two snap-fit ​​plates, and the connecting plate is disposed at one end of the snap-fit ​​plate away from the lower interior panel 2, and a hollow area 212 is formed between the "J"-shaped snap-fit ​​portion 211 and the lower interior panel 2, which facilitates injection molding demoulding on the one hand, and reduces weight on the other hand. The first side surface 211a is provided with a first stop protrusion 211c, which is arranged close to the clamping end, and the first stop protrusion 211c and the first side surface 211a form a first limiting step 214; the second side surface 211b is provided with a second stop protrusion 211d, which is arranged on the side of the first stop protrusion 211c facing the upper interior panel 1 or the lower interior panel 2, and the second stop protrusion 211d and the second side surface 211b form a second limiting step 215.

[0029] Optionally, the snap-fit ​​buckle 21 further includes a connecting portion 213, which is connected to the side of the snap-fit ​​buckle 211 facing the fourth limiting surface 111b to improve the strength of the snap-fit ​​buckle 21. The connecting portion 213 can also be arranged on the side of the snap-fit ​​buckle 211 facing the third limiting surface 111a. The first stop protrusion 211c, the first side surface 211a and the connecting portion 213 together form a groove portion (not shown), which can limit the limiting protrusion 112 in the first direction Z.

[0030] Optionally, continue to Figure 3 , the second stop protrusion 211d extends to and is connected with the lower interior panel 2. Specifically, the second stop protrusion 211d is a plate-like structure, extending to the lower interior panel 2 along the second direction Y to further enhance the strength of the snap-fit ​​buckle 21. Optionally, the snap-fit ​​buckle 21 further includes a reinforcing rib 216, which is connected between the lower interior panel 2 and the second stop protrusion 211d.

[0031] See also Figure 4 , Figure 4 for Figure 1 In the partial cross-sectional view perpendicular to the first direction, in the second direction Y, the first limiting surface 112a and the end surface 113a of the stopper of the limiting plate 113 respectively stop the first side surface 211a and the second side surface 211b of the snap-fit ​​buckle 21, thereby limiting the relative displacement of the upper interior panel 1 and the lower interior panel 2 in the second direction Y; continue to refer to Figure 4In the third direction X, the second limiting surface 112b stops the first stop protrusion 211c of the snap buckle 21 facing the side of the lower interior panel 2, and the first inner side surface 113b of the limiting plate 113 stops the second stop protrusion 211d of the snap buckle 21 away from the side of the lower interior panel 2, thereby limiting the relative displacement of the upper interior panel 1 and the lower interior panel 2 in the third direction X.

[0032] Optionally, continue to Figure 4 , a chamfer 112c is provided at the intersection of the first limiting surface 112a and the second limiting surface 112b. During the assembly process, the limiting protrusion 112 gradually approaches the first limiting step 214, at which time the chamfer 112c fits with the first stop protrusion 211c and plays a guiding role, so that the limiting protrusion moves along the first stop protrusion 211c toward the side of the lower interior panel 2, and finally abuts against the first limiting step 214, thereby improving the assembly accuracy and assembly efficiency.

[0033] Optionally, continue to Figure 2 One end of the limit plate 113 is connected to the upper interior panel 1, and at least one weakened groove 114 is provided on the limit plate 113. The weakened groove 114 extends in the same direction (along the second direction Y) as the limit plate 113 and passes through the other end of the limit plate 113. The weakened groove 114 reduces the rigidity of the stopper of the limit plate 113, so that the limit plate 113 has a certain elasticity, and can give way to the direction away from the clamping hole 111 during the assembly process, and reset to the direction close to the clamping hole 111, so as to facilitate the clamping and separation of the limit plate 113 and the second limit step 215, thereby facilitating the assembly and disassembly of the automobile B-pillar 10.

[0034] Optionally, continue to Figure 2 The locking member 11 further comprises two limiting side plates 115 arranged opposite to each other along the first direction Z. The two ends of the limiting side plates 115 are respectively connected to the upper interior panel 1 and the end of the limiting plate 113 in the first direction Z. The two limiting side plates 115 are respectively connected to the two ends of the limiting plate 113 in the first direction Z. The limiting side plates 115 and the limiting plate 113 are arranged around the edge of the clamping hole 111, that is, the two limiting side plates 115 and the limiting plate 113 form a "C"-shaped structure. The "C"-shaped structure and the upper interior panel 1 surround the clamping hole 111. The second inner side surface 115a of at least one limiting side plate 115 facing the clamping hole 111 blocks the surface of the second limiting step 215 facing the limiting side plate 115. The second inner side surface 115a is used to assist the third limiting surface 111a and the fourth limiting surface 111b in positioning the clamping buckle 21 in the first direction Z to improve reliability. In this embodiment, the two second inner side surfaces 115a are coplanar with the third limiting surface 111a and the fourth limiting surface 111b respectively. In other embodiments, the two second inner side surfaces 115a may also be parallel to the third limiting surface 111a and the fourth limiting surface 111b respectively and not coplanar.

[0035] Optionally, continue to Figure 2 , an angle is formed between the third limiting surface 111a and the fourth limiting surface 111b, and the distance between the third limiting surface 111a and the fourth limiting surface 111b gradually decreases along the extension direction of the limiting plate 113. Specifically, along the second direction Y, the distance between the third limiting surface 111a and the fourth limiting surface 111b in the first direction Z gradually increases. Correspondingly, along the second direction Y, the distance between the upper and lower outer surfaces of the snap buckle 21 corresponding to the third limiting surface 111a and the fourth limiting surface 111b in the first direction Z also gradually increases. When the upper interior panel 1 is installed to the lower interior panel 2 along the second direction Y, the distance between the outer surface of the snap buckle 21 and the inner surface of the snap hole 111 gradually decreases, which is beneficial for the snap buckle 21 to align with the snap hole 111 on the one hand, and on the other hand, the third limiting surface 111a and the fourth limiting surface 111b guide the movement of the snap buckle 21, so that the upper interior panel 1 and the lower interior panel 2 are firmly snapped in the first direction Z.

[0036] The present application also provides a car, comprising the car B-pillar 10 in any of the above embodiments. The car of the present application has high reliability.

[0037] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
