[0002] For an automobile, the vehicle body has three columns, which are, in sequence from the front of the vehicle to the rear, the front column (A-pillar), the middle column (B-pillar), and the rear column (C-pillar). According to the assembly, the structure of the column includes a column body sheet metal part and an upper guard plate of the column.

[0003] In the related art, the upper guard plate of the column can be connected to the column body sheet metal part through a buckle structure. The buckle structure and the upper guard plate of the column are integrally formed structural parts.

[0004] However, since the buckle structure and the upper guard plate of the column are integrally formed structural parts, once the buckle structure is damaged, it directly leads to the scrapping of the upper guard plate of the column, thereby increasing the scrapping rate of the upper guard plate of the column. Summary of the Invention

[0005] Embodiments of the present disclosure provide a buckle structure and a guard plate for an automotive guard plate, which can reduce the scrapping rate of the automotive guard plate and meet the requirements of self-disassembly and assembly and functional requirements of the guard plate.

A first end of the arm body is connected to the guard plate clamping plate. The arm body has a first side facing the guard plate clamping plate and a second side opposite to the first side. The first gap is formed between the first side and the guard plate clamping plate.

[0008] The clamping block is connected to the second side, and the clamping block and the second side define a notch, and the notch is located at a second end of the arm body.

[0009] In yet another implementation manner of the present disclosure, the clamping block has a guiding inclined surface, and in the direction from the second end of the arm body to the first end of the arm body, the guiding inclined surface inclines and approaches the clamping plate of the guard plate.

[0010] In yet another implementation manner of the present disclosure, there are two flexible arms, and the two flexible arms are symmetrically located on the opposite side edges of the clamping plate of the guard plate, and the symmetry plane of the two flexible arms passes through the axis of the connecting column.

[0011] In yet another implementation manner of the present disclosure, the sheet metal part connector includes an intermediate column body and clamping claws. The clamping claws are located on the outer periphery of the intermediate column body, and the clamping claws are connected to the first end of the intermediate column body. A second gap is formed between the clamping claws and the intermediate column body, and the direction in which the width of the second gap is located is perpendicular to the axis direction of the intermediate column body; the intermediate column body is perpendicular to the clamping plate of the guard plate, and the second end of the intermediate column body is connected to the clamping plate of the guard plate.

[0012] In yet another implementation manner of the present disclosure, the clamping claws include two clamping pieces, the two clamping pieces are respectively located on the opposite sides of the intermediate column body, and are respectively connected to the first end of the intermediate column body. The two clamping pieces respectively form the second gap with the intermediate column body; in the direction from the first end of the intermediate column body to the second end of the intermediate column body, the width of the second gap gradually decreases.

[0013] In yet another implementation manner of the present disclosure, the clamping pieces both have a recessed groove, and the recessed groove is located on the outer periphery of the side of the clamping piece close to the clamping plate of the guard plate.

[0014] In yet another implementation manner of the present disclosure, the sheet metal part connector further includes two clamping pieces, the two clamping pieces are symmetrically located on the opposite sides of the intermediate column body along the central axis of the intermediate column body, and each clamping piece is located between the two clamping claws; the two clamping pieces are respectively connected to the outer wall of the second end of the intermediate column body, and in the direction from the first end of the intermediate column body to the second end of the intermediate column body, the gap between each clamping piece and the intermediate column body gradually increases.

[0015] In yet another implementation manner of the present disclosure, the buckle structure is a polyoxymethylene resin structural part.

[0016] In yet another implementation of the present disclosure, a guard plate is further provided. The guard plate is an upper guard plate for an automotive pillar.

The first connecting plate and the second connecting plate are arranged in parallel, and the first connecting plate is connected to the guard plate main body portion to form a receiving cavity for receiving the base of the snap structure. The middle of the first connecting plate has a limiting groove that engages with the connecting column, and the limiting groove communicates with the receiving cavity. The second connecting plate is connected to the guard plate main body portion, and the inner wall of the second connecting plate abuts against the flexible arm and the guard plate clamping plate of the snap structure.

[0017] The beneficial effects brought by the technical solutions provided in the embodiments of the present disclosure are as follows:

[0019] Moreover, since the guard plate connecting member includes a base, a connecting column, a guard plate clamping plate, and a flexible arm, and a first gap is formed between the side where the flexible arm is connected to the guard plate clamping plate. In this way, when the guard plate connecting member is connected to the guard plate of the automobile, the width of the first gap can be adjusted by controlling the flexible arm to ensure that the flexible arm and the guard plate clamping plate are integrally installed inside the guard plate of the automobile, realizing a detachable connection between the guard plate clamping plate and the guard plate of the automobile. At the same time, the outer wall of the connecting column can abut against the guard plate of the automobile, and the base can be movably located inside the guard plate of the automobile, ultimately improving the connection firmness between the guard plate connecting member and the guard plate of the automobile.

[0020] That is to say, in the present application, by controlling the width of the first gap, a detachable connection between the guard plate connecting member and the guard plate of the automobile can be realized. In this way, after the snap structure is damaged, a new snap structure can be directly replaced and installed on the guard plate of the automobile, without having to scrap the guard plate of the automobile together, thereby extending the service life of the guard plate of the automobile and reducing the manufacturing cost of the automobile.

[0033] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0034] To clearly illustrate the buckle structure provided by the embodiments of the present disclosure, a brief description of the interior parts of the vehicle will be given first.

[0035] For an automobile, the vehicle body has three columns. Along the direction from the front of the vehicle to the rear, they are the front column (A-pillar), the middle column (B-pillar), and the rear column (C-pillar) in sequence. Generally, the A-pillar is located between the engine compartment and the driver's cabin and above the left and right rearview mirrors. The B-pillar is located between the front seat and the rear seat in the driver's cabin, that is, between the front door and the rear door of the vehicle. The C-pillar is located on both sides of the rear seat headrest. For an automobile, in addition to the supporting function, the columns also act as door frames.

[0036] In terms of assembly, the structure of the column includes a column body sheet metal part and a guard plate. Among them, the guard plate is connected to the column body sheet metal part through a snap structure. For example, the C-pillar includes a C-pillar guard plate and a C-pillar sheet metal part, and the C-pillar guard plate is connected to the outer wall of the C-pillar sheet metal through a snap structure.

[0037] An embodiment of the present disclosure provides a snap structure, as Figure 1 shown. The snap structure includes a guard plate connecting part 1 and a sheet metal part connecting part 2.

[0038] The guard plate connecting part 1 includes a base 11, a connecting column 12, a guard plate clamping plate 13, and a flexible arm 14. The base 11 and the guard plate clamping plate 13 are parallel, and both ends of the connecting column 12 are connected to the base 11 and the guard plate clamping plate 13 respectively.

[0039] Figure 2 is a top view of the snap structure provided by the embodiment of the present disclosure, combined with Figure 2 . One end of the flexible arm 14 is connected to one side edge of the guard plate clamping plate 13 and extends along the connected side edge. There is a first gap 15 between the flexible arm 14 and the connected side edge of the guard plate clamping plate 13 in the direction parallel to the plate surface of the guard plate clamping plate 13.

[0040] The sheet metal part connecting part 2 is located on the side opposite to the side where the guard plate clamping plate 13 and the base 11 are located, and the sheet metal part connecting part 2 is connected to the guard plate clamping plate 13.

[0041] Continue to refer to Figure 2 . The direction in which the width of the first gap 15 is located is perpendicular to the connecting column 12. The base 11 is used to be movably located in the receiving cavity 104 of the guard plate of the automobile, and the moving direction of the base 11 is perpendicular to the direction in which the width of the first gap 15 is located. The guard plate clamping plate 13 and the flexible arm 14 are in contact with the side edge of the guard plate of the automobile. The sheet metal part connecting part 2 is used to be detachably connected to the column body sheet metal part of the automobile.

[0042] When the snap structure provided by the embodiment of the present disclosure is used on an automobile, since the snap structure includes a guard plate connecting part 1 and a sheet metal part connecting part 2, the snap structure can be connected to the guard plate of the automobile through the guard plate connecting part 1, and at the same time, the snap structure can be connected to the column body sheet metal part of the automobile through the sheet metal part connecting part 2.

[0043] Also, since the guard plate connecting member 1 includes a base 11, a connecting column 12, a guard plate clamping plate 13, and a flexible arm 14, a first gap 15 is formed between the side where the flexible arm 14 is connected to the guard plate clamping plate 13. In this way, when the guard plate connecting member 1 is connected to the guard plate of the vehicle, the width of the first gap 15 can be adjusted by controlling the flexible arm 14, ensuring that the flexible arm 14 and the guard plate clamping plate 13 are integrally clamped in the clamping groove 1031 of the vehicle's guard plate (the structure of the guard plate will be described in detail below), realizing the detachable connection between the guard plate clamping plate 13 and the vehicle's guard plate. At the same time, the outer wall of the connecting column 12 can be abutted against the limiting groove 1021 of the vehicle's guard plate, and the base 11 can be movably located within the receiving cavity 104 of the vehicle's guard plate, ultimately improving the connection firmness between the guard plate connecting member 1 and the vehicle's guard plate.

[0044] That is to say, in this application, by controlling the flexible arm 14, the width of the first gap 15 can be changed, so that the detachable connection between the guard plate connecting member 1 and the vehicle's guard plate can be realized. When the buckle structure is damaged, a new buckle structure can be directly replaced and installed on the vehicle's guard plate, without scrapping the vehicle's guard plate together, thereby extending the service life of the vehicle's guard plate and reducing the manufacturing cost of the vehicle.

[0045] Continue to refer to Figure 2 , optionally, the flexible arm 14 includes a clamping block 141 and an arm body 142. The first end of the arm body 142 is connected to the guard plate clamping plate 13. The arm body 142 has a first side facing the guard plate clamping plate 13 and a second side opposite to the first side, and the first gap 15 is formed between the first side and the guard plate clamping plate 13.

[0046] The clamping block 141 is connected to the second side, and the clamping block 141 and the second side define a notch 143, and the notch 143 is located at the second end of the arm body 142.

[0047] In the above implementation, the arm body 142 is used to be connected to the guard plate clamping plate 13 and at the same time form a first gap 15 with the guard plate clamping plate 13. The clamping block 141 is used to be clamped with the inner wall of the clamping groove 1031 of the vehicle's guard plate to improve the connection firmness between the guard plate connecting member 1 and the vehicle's guard plate. The notch 143 can increase the clamping engagement degree between the guard plate clamping plate 13 and the inner wall of the clamping groove 1031 of the vehicle's guard plate, so as to further increase the connection firmness between the two.

[0048] In this embodiment, the opening angle of the notch 143 is 100 degrees. Along the direction perpendicular to the arm body 142, the maximum length of the opposite sides of the guard plate clamping plate 13 is 24 mm, and the minimum length is 19 mm.

[0049] Continue to refer toFigure 2 , optionally, the snap block 141 has a guiding inclined surface 1411, and in the direction from the second end of the arm body 142 to the first end of the arm body 142, the guiding inclined surface 1411 inclines and approaches the guard plate snap plate 13.

[0050] In the above implementation, the guiding inclined surface 1411 is provided on the snap block 141, and in the direction from one end of the arm body 142 to the other end (that is, along the direction of the guard plate connector 1 towards the guard plate of the vehicle), the guiding inclined surface 1411 gradually approaches one side of the guard plate snap plate 13. In this way, when installing the guard plate connector 1 on the guard plate of the vehicle, the inclination of the guiding inclined surface 1411 enables the snap block 141 to be quickly inserted into the corresponding snap groove 1031 of the guard plate of the vehicle and fit and snap together with the inner wall of the snap groove 1031 of the guard plate of the vehicle.

[0051] , optionally, there are two flexible arms 14, and the two flexible arms 14 are symmetrically located on the opposite sides of the guard plate snap plate 13, and the symmetry plane of the two flexible arms 14 passes through the axis of the connecting column 12.

[0052] In the above implementation, the arrangement of the two flexible arms 14 can increase the number of the first gaps 15, and further increase the deformation degree of the flexible arms 14 relative to the guard plate snap plate 13, so as to improve the disassembly and assembly efficiency of the guard plate connector 1 on the guard plate of the vehicle.

[0053] Moreover, the arrangement of the two flexible arms 14 can also increase the snap connection degree between the guard plate snap plate 13 and the guard plate of the vehicle, so as to further increase the connection strength between the guard plate connector 1 and the guard plate of the vehicle.

[0054] Figure 3 is a cross-sectional view of the snap structure provided by the embodiment of the present disclosure, combined with Figure 3 , optionally, the sheet metal part connector 2 includes an intermediate column 21 and a clamping jaw 22. The clamping jaw 22 is located on the outer periphery of the intermediate column 21, and the clamping jaw 22 is connected to the first end of the intermediate column 21. A second gap 23 is formed between the clamping jaw 22 and the intermediate column 21, and the direction in which the width of the second gap 23 is located is perpendicular to the axis direction of the intermediate column 21.

[0055] The intermediate column 21 is perpendicular to the guard plate snap plate 13, and the second end of the intermediate column 21 is connected to the guard plate snap plate 13.

[0056] In the above implementation, the intermediate column 21 is used to connect the guard plate snap plate 13 and the clamping jaw 22 to provide an installation basis for the clamping jaw 22. The clamping jaw 22 is used for detachably connecting with the column sheet metal part of the vehicle. Moreover, the existence of the second gap 23 enables the clamping jaw 22 to move relative to the intermediate column 21, so that it is convenient for the clamping jaw 22 to be inserted into the column sheet metal part of the vehicle.

[0057] Exemplarily, when the jaw 22 is actually connected to the column sheet metal part of the vehicle, the jaw 22 is inserted into the corresponding mounting hole of the column sheet metal part of the vehicle.

[0058] Continue to refer to Figure 3 , optionally, the jaw 22 includes two clamping pieces 221, the two clamping pieces 221 are respectively located on opposite sides of the middle column 21, and are respectively connected to the first end of the middle column 21, and a second gap 23 is respectively formed between the two clamping pieces 221 and the middle column 21.

[0059] In the direction from the first end of the middle column 21 to the second end of the middle column 21 (the direction a in Figure 3 can be referred to), the width of the second gap 23 (the distance d2 in Figure 3 can be referred to) gradually decreases.

[0060] In the above implementation manner, the jaw 22 is provided with two clamping pieces 221, so that a second gap 23 can be formed between the clamping pieces 221 and the middle column 21, so that the jaw 22 can move relative to the middle column 21, and a detachable connection between the jaw 22 and the column sheet metal part can be realized.

[0061] Moreover, setting the width of the second gap 23 to the above structure can, on the one hand, enable the clamping piece 221 to form a guiding structure, that is, when the jaw 22 is installed on the column sheet metal part, it can be smoothly inserted into the mounting hole of the column sheet metal part through this guiding structure. On the other hand, it can also cause the side of the clamping piece 221 away from the column sheet metal part to rapidly contract under the action of an external pressure, so that the outer diameter of the jaw 22 can be smaller than the size of the mounting hole on the column sheet metal part, thereby facilitating the installation of the jaw 22 on the column sheet metal part or the removal of the jaw 22 from the column sheet metal part, and realizing the detachable connection between the jaw 22 and the column sheet metal part.

[0062] During actual installation, when it is necessary to remove the sheet metal part connector 2 from the column sheet metal part, the two clamping pieces 221 can be squeezed, so that the width of the second gap 23 is reduced, so that the sheet metal part connector 2 can be disengaged from the mounting hole of the column sheet metal part. When it is necessary to insert the sheet metal part connector 2 into the column sheet metal part, the two clamping pieces 221 are also squeezed first to insert the sheet metal part connector 2 into the mounting hole of the column sheet metal part, and after installation, it is not necessary to continue squeezing the two clamping pieces 221, but the clamping pieces 221 automatically rebound and are clamped together with the column sheet metal part.

[0063] As mentioned above, in the direction from the first end of the middle column 21 to the second end of the middle column 21, the width of the second gap 23 gradually decreases, which means that in the direction from the first end of the middle column 21 to the second end of the middle column 21, the jaw 22 is in a contracted state relative to the middle column 21.

[0064] Optionally, each clamping piece 221 has a concave groove 223, and the concave groove 223 is located on the outer periphery of the corresponding clamping piece 221 on the side close to the guard plate clamping plate 13. Among them, the concave groove 223 is used for clamping with the column sheet metal part of the vehicle.

[0065] In the above implementation, the formation of the concave groove 223 can be clamped with the column sheet metal part, that is, the two clamping pieces 221 can interfere with the column sheet metal part respectively, so as to facilitate the detachable connection between the clamping jaw 22 and the column sheet metal part.

[0066] In this embodiment, the opening size of the mounting hole on the column sheet metal part is 15.4 * 12 mm. The interference amount between the clamping jaw 22 and the column sheet metal part is 0.8 mm.

[0067] In this embodiment, in order to facilitate the two clamping pieces 221 to be smoothly inserted into the mounting hole of the column sheet metal part of the vehicle, when the two clamping pieces 221 are connected to the first end of the middle column 21, the two clamping pieces 221 are connected to each other and form a conical arc shape.

[0068] Figure 4 It is a side view of the buckle structure provided by the embodiment of the present disclosure, combined with Figure 4 , optionally, the sheet metal connecting piece 2 further includes two clamping pieces 24, and the two clamping pieces 24 are symmetrically located on the opposite sides of the middle column 21 along the central axis of the middle column 21, and each clamping piece 24 is located between the two clamping pieces 221.

[0069] The two clamping pieces 24 are respectively connected to the outer wall of the second end of the middle column 21. From the first end of the middle column 21 to the second end of the middle column 21 (the direction b in Figure 4 can be referred to), the gap between each clamping piece 24 and the middle column 21 (the distance d3 in Figure 4 can be referred to) gradually increases.

[0070] The two clamping pieces 24 are respectively used for abutting against the column sheet metal part of the vehicle.

[0071] In the above implementation, by setting the two clamping pieces 24, the connection relationship between the sheet metal connecting piece 2 and the column sheet metal part can be further increased, so that the connection firmness between the sheet metal connecting piece 2 and the column sheet metal part can be increased.

[0072] That is to say, when the clamping jaw 22 is inserted into the corresponding mounting hole of the column sheet metal part, the two clamping pieces 24 can just abut against the column sheet metal part. In this way, the column sheet metal part can be firmly limited in the concave groove 223. That is, under the action of the concave groove 223 and the two clamping pieces 24, the column sheet metal part is firmly connected with the clamping jaw 22, so as to increase the connection firmness between the sheet metal connecting piece 2 and the column sheet metal part.

[0073] Moreover, setting the two clamping pieces 24 in the above structure enables the two clamping pieces 24 to abut against the column-shaped sheet metal part while not affecting the process of inserting the clamping jaw 22 into the corresponding mounting hole of the column-shaped sheet metal part. At the same time, different sheet metal thicknesses can be tolerated through the clamping piece 24.

[0074] Exemplarily, the thickness of each of the two clamping pieces 24 is 0.65 mm. The interference amount between the two clamping pieces 24 and the column-shaped sheet metal part is 0.67 mm. And the angle between the clamping piece 24 and the guard plate clamping plate 13 is 20 degrees. A clamping guide surface is provided on the outer edge of the guard plate clamping plate 13, and the included angle between the clamping guide surface and the plane where the guard plate clamping plate 13 is located is 153.5°. A base guide surface is also provided on the outer edge of the base 11, and the included angle between the base guide surface and the plane where the base 11 is located is 170°.

[0075] As mentioned above, in the direction from the first end of the middle column 21 to the second end of the middle column 21, the gap between each clamping piece 24 and the middle column 21 gradually increases, which means that in the direction from the first end of the middle column 21 to the second end of the middle column 21, the clamping piece 24 gradually moves away from the middle column 21.

[0076] Optionally, the buckle structure is a polyoxymethylene resin structural part.

[0077] In the above implementation, setting the buckle structure as a polyoxymethylene resin structural part can endow the buckle structure with good anti-creep characteristics, geometric stability and anti-impact characteristics through the polyoxymethylene resin, thereby prolonging the service life of the buckle structure.

[0078] The above buckle structure is an anti-loosening fastening buckle structure. After the buckle structure is connected to the automotive fender, it can be used as the main positioning structure of the automotive fender to be connected to the column-shaped sheet metal part. By designing reasonable interference amounts, clamping angles, holding angles, etc., the buckle structure can be in interference fit with the column-shaped sheet metal part, thereby enhancing the connection strength between the automotive fender and the column-shaped sheet metal part.

[0079] The disassembly and assembly between this buckle structure and the column-shaped sheet metal part are also convenient. When it is necessary to disassemble the buckle structure from the column-shaped sheet metal part, a flat-head screwdriver is used to apply force to the concave groove 223 of the buckle structure to disengage the buckle structure from the column-shaped sheet metal part, thus completing the disassembly between the automotive fender and the column-shaped sheet metal part. If the buckle structure is damaged and fails due to improper disassembly, the buckle structure can also be removed from the automotive fender and replaced.

[0080] Next, taking the application of this buckle structure to the upper fender of the C-pillar of an automobile as an example to illustrate the disassembly and installation process of the buckle structure. That is, at this time, the buckle structure is used to connect the upper fender of the C-pillar and the C-pillar sheet metal part.

[0081] Figure 5 It is an installation schematic diagram between the buckle structure provided by the embodiments of the present disclosure and the upper C-pillar trim of an automobile. Combining Figure 5 , in this embodiment, in order to achieve detachable installation between the trim of the automobile and the buckle structure. The upper C-pillar trim includes a trim main body portion 101, a first connecting plate 102 and a second connecting plate 103.
