When the second mounting member is located at the ending position, the protruding portion is inside the clamping hole.

[0007] In an exemplary embodiment of the present application, the clamping portion includes a bottom plate segment and a clamping segment. The clamping segment is connected to the bottom plate segment, passes through the clamping hole, and is clamped with the second mounting member. The guiding portion is connected to the bottom plate segment and is spaced apart from the clamping segment. The second mounting member is provided with a groove that communicates with the second through hole and the clamping hole. The bottom plate segment is located in the groove and is spaced apart from the groove wall.

[0008] In an exemplary embodiment of the present application, the clamping segment includes a clamping end and a connecting end. The connecting end is connected between the clamping end and the bottom plate segment. The connecting end is located in the clamping hole, and the clamping end is located outside the clamping hole and is clamped with the second mounting member. Wherein, the cross-sectional area of the clamping end gradually decreases along the direction from the bottom plate segment towards the connecting end.

[0009] In an exemplary embodiment of the present application, the clamping end includes a first clamping surface, a second clamping surface, a third clamping surface, and a limiting surface. The second clamping surface is connected between the first clamping surface and the third clamping surface. The third clamping surface is connected to the limiting surface. The first clamping surface and the limiting surface are both connected to the connecting end. The limiting surface is connected to the second mounting member. The second clamping surface is used to contact the first mounting member.

[0010] In an exemplary embodiment of the present application, the second mounting member is provided with a plurality of spaced-apart clamping holes that surround the second through hole. The clamping portion includes a plurality of spaced-apart clamping segments that surround the guiding portion. The plurality of clamping segments are respectively clamped in the plurality of clamping holes.

[0011] In an exemplary embodiment of the present application, the cross-sectional area of the guiding portion gradually decreases along the direction from the second mounting member towards the first mounting member.

[0012] In an exemplary embodiment of the present application, the first body part includes an integral first plate surface and a first mounting seat. The first mounting seat protrudes relative to the first plate surface. The protruding part is connected to the first mounting seat, and the first through hole is located in the first mounting seat. The second mounting member includes an integral second plate surface and a second mounting seat. The second mounting seat protrudes relative to the second plate surface. The second through hole and the clamping hole are both located in the second mounting seat, and the second mounting seat is arranged corresponding to the first mounting seat.

[0014] A second aspect of the present application discloses a vehicle, including a vehicle frame and the vehicle body structure as described above, and the vehicle body structure is connected to the vehicle frame.

[0015] The beneficial effects of the solution of the present application are:

[0016] In the embodiment of the present application, when the second mounting member needs to be mounted on the first mounting member, the guiding part of the guiding structure can be first passed through the second through hole, and the clamping part of the guiding structure is clamped on the second mounting member. Then, the second mounting member and the guiding structure are synchronously moved in the direction close to the first mounting member (i.e., the first mounting stroke). At this time, the guiding part passes through the first through hole, and the first mounting member is spaced from the clamping part. The guiding part can guide the mounting of the second mounting member. Then, the second mounting member is continuously moved in the direction close to the first mounting member (i.e., the second mounting stroke). At this time, since the first mounting member is in contact with the clamping part, the guiding structure moves in the direction away from the first mounting member to separate the second mounting member from the guiding structure, thereby realizing the automatic dropping of the guiding structure. Therefore, the vehicle body structure of the present application not only has a guiding function, but also can realize the automatic dropping of the guiding structure, avoiding interference between the guiding structure and other components.

[0017] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present application. Description of the Drawings

Detailed implementation manners

[0027] The following will illustrate the implementation manners of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0028] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0029] This embodiment provides a vehicle body structure, including: a first mounting member 1, a second mounting member 2, and a guiding structure 3. The first mounting member 1 is provided with a first through hole 101; the second mounting member 2 is used to be mounted on the first mounting member 1, and the second mounting member 2 is provided with a second through hole 201 and a clamping hole 202 that are spaced apart from each other. The second through hole 201 is correspondingly arranged with the first through hole 101; the guiding structure 3 includes a guiding portion 31 and a clamping portion 32 that are connected to each other. The guiding portion 31 is inserted into the second through hole 201, and the clamping portion 32 is inserted into the clamping hole 202 and is clamped with the second mounting member 2.

[0030] In this embodiment, the first mounting member 1 is a vehicle body sheet metal part, such as an inner door panel, a roof sheet metal, etc.

[0031] In this embodiment, the second mounting member 2 is an interior part of the vehicle or an exterior part of the vehicle, and the interior part of the vehicle or the exterior part of the vehicle needs to be mounted on the vehicle body sheet metal part.

[0032] For example, the interior parts of the vehicle include an instrument panel, a lower instrument panel, an inner door trim, a roof lining, and A / B / C pillar trim panels, etc. The exterior parts of the vehicle include a front bumper, a rear bumper, and an intake grille, etc.

[0033] In other embodiments, the first mounting member 1 can be a plastic part, such as the lower guard plate of the inner door trim.

[0034] For example, the inner door trim includes an upper guard plate and a lower guard plate. The lower guard plate is connected to the inner door panel, and the upper guard plate is connected to the lower guard plate; wherein, the upper guard plate is used to provide an elbow rest, and the lower guard plate is usually used as the door trim skeleton. If the lower guard plate needs to be mounted on the inner door panel, then the inner door panel is the first mounting member 1 and the lower guard plate is the second mounting member 2. If the upper guard plate needs to be mounted on the lower guard plate, then the lower guard plate is the first mounting member 1 and the upper guard plate is the second mounting member 2.

[0035] It should be understood that the upper guard plate is a plastic integral structure; the lower guard plate is a plastic integral structure.

[0036] Further, the second mounting member 2 has a first mounting stroke and a second mounting stroke. When the second mounting member 2 moves within the first mounting stroke, the second mounting member 2 and the guiding structure 3 move synchronously in a direction approaching the first mounting member 1. The guiding portion 31 penetrates through the first through-hole 101, and the first mounting member 1 is spaced apart from the engaging portion 32. When the second mounting member 2 moves within the second mounting stroke, the second mounting member 2 moves in a direction approaching the first mounting member 1, the first mounting member 1 comes into contact with the engaging portion 32, the guiding structure 3 moves in a direction away from the first mounting member 1, and the second mounting member 2 is separated from the guiding structure 3.

[0037] In this embodiment, when the second mounting member 2 needs to be mounted on the first mounting member 1, the guiding portion 31 of the guiding structure 3 can be first penetrated through the second through-hole 201, and the engaging portion 32 of the guiding structure 3 is engaged with the second mounting member 2. Then, the second mounting member 2 and the guiding structure 3 are moved synchronously in a direction approaching the first mounting member 1 (i.e., the first mounting stroke). At this time, the guiding portion 31 penetrates through the first through-hole 101, the first mounting member 1 is spaced apart from the engaging portion 32, and the guiding portion 31 can guide the mounting of the second mounting member 2. Then, the second mounting member 2 is continuously moved in a direction approaching the first mounting member 1 (i.e., the second mounting stroke). At this time, since the first mounting member 1 comes into contact with the engaging portion 32, the guiding structure 3 moves in a direction away from the first mounting member 1 to separate the second mounting member 2 from the guiding structure 3, thereby realizing the automatic dropping of the guiding structure 3. Therefore, the body structure of the present application not only has a guiding function but also can realize the automatic dropping of the guiding structure 3, avoiding interference between the guiding structure 3 and other components.

[0038] It should be understood that since the guiding structure 3 can be automatically dropped and the guiding structure 3 will not interfere with other components, the length of the guiding portion 31 can be increased to meet the requirement of increasing the length of the guiding portion 31 for the assembly of other components.

[0039] In this embodiment, the length of the guiding portion 31 can be greater than 10 mm.

[0040] For example, the length of the guiding portion 31 can be 11 mm, 12 mm, 13 mm, etc.

[0041] Combined Figure 3 and Figure 4 As shown, the first mounting member 1 includes a first body portion 11 and a protruding portion 12. The protruding portion 12 protrudes relative to the first body portion 11 and is connected to the first body portion 11. The protruding portion 12 is correspondingly arranged with the engaging hole 202, and the first through-hole 101 is located in the first body portion 11. When the second mounting member 2 moves within the first mounting stroke, the protruding portion 12 is spaced apart from the engaging portion 32. When the second mounting member 2 moves within the second mounting stroke, the protruding portion 12 comes into contact with the engaging portion 32.

[0042] It should be understood that since the convex portion 12 protrudes relative to the first body portion 11 and the convex portion 12 is correspondingly arranged with the clamping hole 202, when the second mounting member 2 moves towards the first mounting member 1, the convex portion 12 first comes into contact with the clamping portion 32. After the convex portion 12 comes into contact with the clamping portion 32, the second mounting member 2 continues to move towards the first mounting member 1 until the first body portion 11 comes into contact with the second mounting member 2. At this time, the convex portion 12 will abut the clamping portion 32 outside the clamping hole 202, causing the clamping portion 32 to be separated from the second mounting member 2, so as to separate the guiding structure 3 and the second mounting member 2, and further realize the automatic dropping of the guiding structure 3 to avoid interference between the guiding structure 3 and other components.

[0043] Further, the second mounting stroke includes a starting position and an ending position. When the second mounting member 2 is at the starting position, the convex portion 12 is outside the clamping hole 202; when the second mounting member 2 is at the ending position, the convex portion 12 is inside the clamping hole 202.

[0044] In this embodiment, when the second mounting member 2 is at the ending position, the convex portion 12 is inside the clamping hole 202, and the convex portion 12 can limit the mounting position of the first body portion 11 to avoid positioning failure caused by the dropping of the guiding structure 3.

[0045] Combined Figure 3 and Figure 4 As shown, the clamping portion 32 includes a bottom plate section 321 and a clamping section 322. The clamping section 322 is connected to the bottom plate section 321. The clamping section 322 passes through the clamping hole 202 and is clamped with the second mounting member 2. The guiding portion 31 is connected to the bottom plate section 321 and is spaced from the clamping section 322; the second mounting member 2 is provided with a groove 203, and the groove 203 communicates with the second through hole 201 and the clamping hole 202. The bottom plate section 321 is located in the groove 203 and is spaced from the groove wall of the groove 203.

[0046] In this embodiment, after the guiding structure 3 is separated from the second mounting member 2, the clamping section 322 will move from inside the clamping hole 202 to outside the clamping hole 202, the bottom plate section 321 will move from inside the groove 203 to outside the groove 203, and the guiding portion 31 will move from inside the first through hole 101 and the second through hole 201 to outside the first through hole 101 and the second through hole 201.

[0047] In this embodiment, both the guiding portion 31 and the clamping section 322 are connected to the side of the bottom plate section 321 close to the first mounting member 1, so that the guiding structure 3 can penetrate from one side of the second mounting member 2 along the direction close to the first mounting member 1 and be clamped with the second mounting member 2, thereby ensuring that the guiding structure 3 can penetrate out from the same side of the second mounting member 2 along the direction away from the first mounting member 1.

[0048] In this embodiment, a groove 203 is provided on the side of the second mounting member 2 away from the first mounting member 1, and the bottom plate section 321 is located in the groove 203. When the guiding structure 3 is clamped to the second mounting member 2, the length of the guiding portion 31 passing through the second mounting member 2 is reduced, and thus the length of the guiding portion 31 exposed outside the second mounting member 2 is increased, so as to improve the convenience of installation. In addition, the provision of the groove 203 can also reduce the length of the clamping section 322, thereby facilitating the separation of the clamping section 322 from the second mounting member 2.

[0049] It should be understood that since the bottom plate section 321 is arranged at an interval from the groove wall of the groove 203 when the bottom plate section 321 is located in the groove 203, the diameter of the groove 203 is larger than the diameter of the bottom plate section 321, so as to facilitate the installation of the bottom plate section 321 in the groove 203.

[0050] Combined Figure 4 and Figure 8 As shown, the clamping section 322 includes a clamping end 3221 and a connecting end 3222. The connecting end 3222 is connected between the clamping end 3221 and the bottom plate section 321. The connecting end 3222 is located in the clamping hole 202, and the clamping end 3221 is located outside the clamping hole 202 and is clamped to the second mounting member 2; wherein, the cross-sectional area of the clamping end 3221 gradually decreases along the direction from the bottom plate section 321 towards the connecting end 3222.

[0051] In this embodiment, the cross-sectional area of the clamping end 3221 gradually decreases along the direction from the bottom plate section 321 towards the connecting end 3222, and the clamping end 3221 has a guiding function, so as to facilitate the clamping end 3221 to pass through the clamping hole 202 and be clamped to the second mounting member 2.

[0052] Combined Figure 3 and Figure 8 As shown, the clamping end 3221 includes a first clamping surface 3221a, a second clamping surface 3221b, a third clamping surface 3221c and a limiting surface 3221d. The second clamping surface 3221b is connected between the first clamping surface 3221a and the third clamping surface 3221c. One end of the third clamping surface 3221c away from the second clamping surface 3221b is connected to the limiting surface 3221d. Both the first clamping surface 3221a and the limiting surface 3221d are connected to the connecting end 3222. The limiting surface 3221d is connected to the second mounting member 2, and the second clamping surface 3221b is used to contact the protruding portion 12.

[0053] In this embodiment, when the guiding structure 3 is clamped to the second mounting member 2, the limiting surface 3221d is connected to the side of the second mounting member 2 close to the first body portion 11 to ensure the stability of the clamping between the clamping end 3221 and the second mounting member 2.

[0054] In this embodiment, when the second mounting member 2 moves within the second mounting stroke, the second engaging surface 3221b contacts the protruding portion 12, and the protruding portion 12 abuts the second engaging surface 3221b from the side of the second mounting member 2 close to the first mounting member 1 to the side of the second mounting member 2 away from the first mounting member 1, causing the limiting surface 3221d to separate from the second mounting member 2, thereby realizing the separation of the guiding structure 3 from the second mounting member 2. By the contact between the second engaging surface 3221b and the protruding portion 12, the contact area between the protruding portion 12 and the engaging end 3221 is relatively large, facilitating the separation of the guiding structure 3 from the second mounting member 2.

[0055] It should be understood that the orthographic projection of the protruding portion 12 along the axial direction of the second through hole 201 should be larger than the orthographic projection of the second engaging surface 3221b along the axial direction of the second through hole 201 to ensure that the protruding portion 12 can contact the second engaging surface 3221b, thereby realizing the separation of the guiding structure 3 from the second mounting member 2.

[0056] Combined with Figure 1 and Figure 4 As shown, the second mounting member 2 is provided with a plurality of spaced-apart engaging holes 202, and the plurality of engaging holes 202 are arranged around the second through hole 201; the engaging portion 32 includes a plurality of spaced-apart engaging segments 322, and the plurality of engaging segments 322 are arranged around the guiding portion 31, and the plurality of engaging segments 322 are respectively engaged in the plurality of engaging holes 202.

[0057] In this embodiment, the second mounting member 2 is provided with four engaging holes 202, the four engaging holes 202 are arranged around the second through hole 201, and the distance between adjacent two engaging holes 202 is equal; the engaging portion 32 includes four engaging segments 322, the four engaging segments 322 are arranged around the guiding portion 31, and the distance between adjacent two engaging segments 322 is equal. The four engaging segments 322 are respectively engaged in the four engaging holes 202, which is beneficial to improving the engaging strength between the guiding structure 3 and the second mounting member 2 and avoiding the engaging failure between the guiding structure 3 and the second mounting member 2 when the guiding structure 3 and the second mounting member 2 move synchronously.

[0058] In this embodiment, combined with Figure 2 As shown, the cross-sectional area of the guiding portion 31 gradually decreases along the direction of the second mounting member 2 towards the first mounting member 1. The guiding portion 31 has a certain guiding effect to facilitate the installation of the second mounting member 2 on the first mounting member 1.

[0059] It should be understood that when the second mounting member 2 is installed on the first mounting member 1, after the guiding portion 31 passes through the first through hole 101, the guiding portion 31 can move along the axial direction of the first through hole 101 to ensure that the second mounting member 2 can be accurately installed on the first mounting member 1.

[0060] Combined with Figure 1and Figure 5 As shown in Figure 5 , the first body part 11 includes an integral first plate surface 111 and a first mounting seat 112. The first mounting seat 112 protrudes relative to the first plate surface 111. The protruding part 12 is connected to the first mounting seat 112, and the first through hole 101 is located in the first mounting seat 112. The second mounting member 2 includes an integral second plate surface 21 and a second mounting seat 22. The second mounting seat 22 protrudes relative to the second plate surface 21. The second through hole 201 and the clamping hole 202 are both located in the second mounting seat 22, and the second mounting seat 22 is arranged corresponding to the first mounting seat 112.

[0061] In this embodiment, since the second mounting seat 22 is arranged corresponding to the first mounting seat 112, when the second mounting member 2 moves towards the direction close to the first mounting member 1, through the alignment of the second mounting seat 22 and the first mounting seat 112, the preliminary alignment of the second mounting member 2 and the first mounting member 1 can be realized, which is beneficial to improving the convenience of installation. In addition, the second mounting seat 22 protrudes relative to the second plate surface 21, so that the guiding structure 3 can be quickly installed in the second mounting seat 22, facilitating the installation operation for the installer.

[0062] In this embodiment, the first mounting member 1 is provided with a first mounting hole, and the first mounting hole is arranged at an interval from the first through hole 101. The second mounting member 2 is provided with a second mounting hole, and the second mounting hole is arranged at an interval from the second through hole 201 and the clamping hole 202. The vehicle body structure further includes a fastener, and the fastener passes through the first mounting hole and the second mounting hole, and the fastener is used for connecting the first mounting member 1 and the second mounting member 2.

[0063] In this embodiment, the first mounting hole is located in the first plate surface 111, and the second mounting hole is located in the second plate surface 21. When the second mounting member 2 is in the end position, the fastener passes through the first mounting hole and the second mounting hole to connect the first mounting member 1 and the second mounting member 2, thereby realizing the installation of the second mounting member 2 on the first mounting member 1.

[0064] For example, the fastener can be a screw or a bolt.

[0065] This embodiment also proposes a vehicle, including a vehicle frame and the above-mentioned vehicle body structure, and the vehicle body structure is connected to the vehicle frame.
