[0032] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, the following further details the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0033] It should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "middle", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model.

[0034] As Figure 1 、 Figure 7 and Figure 8 shown, a combination buckle mechanism provided by the first embodiment of the present utility model includes a buckle member 1 and a positioning cylinder 2. The positioning cylinder 2 is provided with a through hole 21 and at least two side holes 22 communicating with the through hole 21. The buckle member 1 includes a buckle body 11 and at least two elastic clamping arms 12 connecting the buckle body 11. It can be understood that the elastic clamping arms 12 and the buckle body 11 are integrally formed. The number of the elastic clamping arms 12 is equal to the number of the side holes 22, and the number of the elastic clamping arms 12 can be set according to actual needs. For example, the elastic clamping arms 12 are provided with 2, 3, 4, etc. Preferably, a plurality of the elastic clamping arms 12 are annularly and spacedly connected to the buckle body 11, and a plurality of the side holes 22 are annularly and spacedly arranged on the side wall of the positioning cylinder 2.

[0035] The buckle body 11 is detachably inserted into the through hole 12, and the elastic clamping arms 12 respectively pass through the side holes 22 (that is, the buckle body 11 is detachably inserted into the through hole 21 through the elastic clamping arms 12 respectively passing through the side holes 22). It can be understood that when the buckle member 1 is installed in the positioning cylinder 2, the buckle body 11 is inserted into the through hole 21, a part of the elastic clamping arm 12 is located in the through hole 21, and the other end of the elastic clamping arm 12 passes through the side hole 22 and extends into the external environment.

[0036] In the present invention, the positioning cylinder 2 is provided with a through hole 21 and at least two side holes 22 connected to the through hole 21. The clip 1 includes a clip body 11 and at least two elastic clip arms 12 connected to the clip body 11. The clip body 11 is detachably inserted in the through hole 21 through the elastic clip arms 12 passing through the side holes 22 in a one-to-one correspondence. When the clip 1 is installed on the positioning cylinder 2, the positioning cylinder 2 is inserted in the mounting hole of the external component, and the positioning cylinder 2 extends from the mounting hole to play a positioning role. The elastic clip arms 12 are located outside the mounting hole and can play a pre-hanging function, so that the combined clip mechanism has the functions of pre-hanging and positioning, and only one mounting hole is needed to install the combined clip mechanism on the external component, so that the combined clip mechanism has a small demand for installation space.

[0037] In addition, after the elastic clamp arm 12 is retracted in the through hole 21, the clamp body 11 can be removed from the through hole 21, that is, the disassembly between the clamp member 1 and the positioning cylinder 2 is completed; the positioning cylinder 2 can be used as a positioning member alone, and the disassembly operation between the positioning cylinder 2 and the clamp member 1 is simple. In addition, the disassembly operation between the clamp member 1 and the positioning cylinder 2 is simple, which improves the applicability and versatility of the combined clamp mechanism.

[0038] In one embodiment, if Figures 3 to 6 As shown, the through hole 21 includes a tapered hole 211 and a receiving hole 212 connected to the tapered hole 211, and the inner diameter of the tapered hole 211 gradually decreases from the end close to the receiving hole 212 to the end away from the receiving hole 212; it can be understood that the shape of the receiving hole 212 can be set according to actual needs, and the inner diameter of the end of the tapered hole 211 away from the receiving hole 212 is smaller, and the inner diameter of the end of the tapered hole 211 close to the receiving hole 212 is larger. For further explanation, the axis of the tapered hole 211 and the center line of the receiving hole 212 coincide.

[0039] The buckle body 11 includes a guide column 111 and a guide plate 112 connected to the guide column 111, and all the elastic clamping arms 12 are connected to the guide plate 112; it can be understood that the guide column 111, the guide plate 112 and the elastic clamping arms 12 are an integrally formed part.

[0040] When the buckle 1 is installed on the positioning tube 2 , the guide plate 112 is inserted into the receiving hole 212 , the guide column 111 is inserted into the tapered hole 211 , and the elastic clamping arms 12 pass through the side holes 22 one by one.

[0041] Specifically, when pushing the guide plate 112 towards one end facing the conical hole 211, the conical hole 211 will gradually compress the elastic clamping arms 12, so that the elastic clamping arms 12 can be folded in the inner hole; after the elastic clamping arms 12 are completely received in the conical hole 211, pulling the buckle body 11 towards the end away from the conical hole 211 can pull out the buckle body 11 from the opening of the receiving hole 212, thus completing the disassembly work between the buckle member 1 and the positioning cylinder 2. In addition, manually squeezing the elastic clamping arms 12 until the elastic clamping arms 12 are folded in the through hole 21, and then pulling the guide plate 112, the buckle body 11 can be pulled out from the opening of the receiving hole 212, thus completing the disassembly work between the buckle member 1 and the positioning cylinder 2.

[0042] In addition, during the process of inserting the buckle body 11 into the through hole 21, the guide post 111 moves in the conical hole 211, so that the guide post 111 can play a guiding role for the movement of the buckle body 11 in the through hole 21. In this embodiment, the disassembly and assembly operations between the buckle member 1 and the positioning cylinder 2 are simple, improving the applicability and versatility of the combined buckle mechanism.

[0043] In one embodiment, as Figure 4 and Figure 8 shown, the positioning cylinder 2 includes a conical cylinder body 23 and a receiving cylinder body 24 connecting the conical cylinder body 23; from one end close to the receiving cylinder body 24 towards the end away from the receiving cylinder body 24, the outer diameter of the conical cylinder body 23 gradually decreases; the conical hole 211 is provided on the conical cylinder body 23, and the receiving hole 212 and the side hole 22 are both provided on the receiving cylinder body 24. It can be understood that the outer diameter of the conical cylinder body 23 at the end away from the receiving cylinder body 24 is smaller, and the outer diameter of the conical cylinder body 23 at the end close to the receiving cylinder body 24 is larger; the conical cylinder body 23 and the receiving cylinder body 24 are integrally formed. In this embodiment, the conical cylinder body 23 can play a role in positioning and guiding.

[0044] In one embodiment, as Figure 5 、 Figure 6 and Figure 8As shown, a step edge 1121 is provided on the guide plate 112; when the buckle member 1 is installed on the positioning cylinder 2, the step edge 1121 abuts against one end of the receiving cylinder body 24 away from the conical cylinder body 23. It can be understood that when the buckle body 11 is inserted into the through hole 21, the step edge 1121 abuts against the edge of the receiving cylinder body 24. Due to the limitation of the step edge 1121, the buckle body 11 cannot be further pushed; when it is necessary to further push the buckle body 11, first, the buckle body 11 needs to be rotated by a preset angle (such as 45 degrees) until the step edge 1121 disengages from the edge of the receiving cylinder body 24. The receiving cylinder body 24 will release the restriction on the guide plate 112, and then the buckle body 11 is pushed forward, and the elastic clamping arm 12 can be received in the conical hole 211.

[0045] In one embodiment, as Figure 1 and Figure 8 shown, a limiting plate 243 is provided on the outer wall of the receiving cylinder body 24, and a limiting space 26 is provided between the limiting plate 243 and the elastic clamping arm 12. It can be understood that the shape of the limiting plate 243 can be set according to actual needs. For example, the limiting plate 243 is designed as a square plate, a disc, etc. Specifically, this combined buckle mechanism is installed on an external component. The conical cylinder body 23 passes through the installation hole of the external component, and the external component is located in the limiting space 26 between the limiting plate 243 and the elastic clamping arm 12. The limiting plate 243 and the elastic clamping arm 12 can prevent the combined buckle mechanism from falling off the external component, ensuring the stability of the combined buckle mechanism installed on the external component.

[0046] In one embodiment, as Figure 5 、 Figure 6 and Figure 8 shown, the receiving cylinder body 24 includes a first cylinder body 241 and a second cylinder body 242 connecting the first cylinder body 241. One end of the first cylinder body 241 away from the second cylinder body 242 is connected to the conical cylinder body 23; the limiting plate 243 is arranged between the first cylinder body 241 and the second cylinder body 242; it can be understood that the conical cylinder body 23, the first cylinder body 241, the limiting plate 243, and the second cylinder body 242 are connected in sequence and are integrally formed.

[0047] The accommodation hole 212 includes a first space 2121 provided on the first cylinder 241 and a second space 2122 provided on the second cylinder 242. One end of the first space 2121 away from the second space 2122 communicates with the tapered hole 211. The side hole 22 is provided on the side wall of the first cylinder 241 and communicates with the first space 2121. It can be understood that the tapered hole 211, the first space 2121, and the second space 2122 are sequentially communicated, and the axis of the tapered hole 211, the axis of the first space 2121, and the center line of the second space 2122 coincide.

[0048] When the buckle 1 is installed on the positioning cylinder 2, the step edge 1121 abuts against the end of the second cylinder 242 away from the first cylinder 241. It can be understood that the width of the end of the guiding plate 112 away from the guiding column 111 is greater than the width or length of the second space 2122 and less than the diagonal length of the second space 2122. The guiding plate 112 is parallel to the length direction or width direction of the second space 2122. The step edge 1121 abuts against the edge of the second cylinder 242, and the end of the guiding plate 112 away from the guiding column 111 can move into the second space 2122. When the guiding plate 112 is rotated to the docking line of the second space 2122, the second cylinder 242 will release the restriction on the step edge 1121, and the end of the guiding plate 112 away from the guiding column 111 can move into the second space 2122. At this time, the guiding plate 112 can be further pushed forward. In this embodiment, the structure of the combined buckle mechanism is simple and the disassembly and assembly operations are convenient. Both the tapered cylinder 23 and the first cylinder 241 can pass through the installation hole of the external component. The limiting plate 243 abuts against the installation surface of the external component, and the elastic clamping arm 12 extends out from the side hole 22 of the first cylinder 241, ensuring the pre-hanging function of the elastic clamping arm 12.

[0049] In a specific embodiment, as Figure 5 、 Figure 6 and Figure 8 shown, the first cylinder 241 is a cylindrical cylinder, the second cylinder 242 is a square cylinder, the first space 2121 is a cylindrical hole, and the second space 2122 is a square hole.

[0050] In an embodiment, as Figure 7As shown, the elastic clamping arm 12 includes an oblique arm 121 and a straight arm 122 connected to the oblique arm 121, and one end of the oblique arm 121 away from the straight arm 122 is connected to the buckle body 11, and the straight arm 122 is arranged parallel to the buckle body 11; it can be understood that the angle between the oblique arm 121 and the buckle body 11 is an acute angle, and the buckle body 11, the oblique arm 121 and the straight arm 122 are an integrally formed part.

[0051] From an end close to the straight arm 122 toward an end away from the straight arm 122 , the distance between the oblique arm 121 and the buckle body 11 gradually decreases.

[0052] Specifically, when the buckle body 11 is pushed toward the tapered hole 211, the inner wall of the tapered hole 211 will compress the oblique arm 121, so that the elastic clamp arm 12 is retracted in the tapered hole 211. In this embodiment, the design of the oblique arm 121 ensures the smoothness of the elastic clamp arm 12 being received in the through hole 21. In addition, the outer member is located in the limiting space 26 between the limiting plate 243 and the straight arm 122, and the outer member cannot drive the elastic clamp arm 12 to be compressed through the straight arm 122, thereby ensuring the stability of the combined buckle mechanism installed on the outer member.

[0053] In one embodiment, if Figure 1 As shown, a snap-on groove 1221 is provided on the elastic clamp arm 12. Specifically, the combined snap-on mechanism is installed on the outer component, the conical cylinder 23 and the first cylinder 241 pass through the mounting hole of the outer component, the outer component is located in the limiting space 26 and the snap-on groove 1221, the limiting plate 243 and the straight arm 122 can prevent the combined snap-on mechanism from falling off from the outer component, and ensure the stability of the combined snap-on mechanism installed on the outer component; in addition, the elastic clamp arm 12 is connected to another outer component through the snap-on groove 1221, further ensuring the pre-hanging function of the combined snap-on mechanism.

[0054] In one embodiment, if Figure 8 As shown, there are at least two elastic snap-on parts 27 on the positioning cylinder 2. It can be understood that the number of the elastic snap-on parts 27 can be set according to actual needs, for example, the elastic snap-on parts 27 are provided with 2, 4, etc. Preferably, the elastic snap-on parts 27 are provided on the side wall of the second cylinder 242. Specifically, at least two side openings are provided on the side wall of the second cylinder 242, and the elastic snap-on parts 27 are connected to the inner walls of the side openings, so that the elastic snap-on parts 27 have a certain elasticity. In this embodiment, the design of the elastic snap-on parts 27 facilitates the disassembly and assembly of the positioning cylinder 2.

[0055] In summary, the disassembly and assembly steps between the buckle 1 and the positioning cylinder 2 are: first, rotate the guide plate 112 until the step edge 1121 of the guide plate 112 is separated from the edge of the second cylinder 242; then, push the guide plate 112 forward, and due to the restriction of the inner wall of the conical hole 211 on the elastic clamping arm 12, the elastic clamping arm 12 will gradually retract into the conical hole 211; finally, pull the guide plate 112 backward, and the buckle body 11 can be removed from the opening of the second space 2122 away from the end of the first space 2121.

[0056] Another embodiment of the utility model further provides a vehicle, comprising the above-mentioned combined buckle mechanism.

[0057] When the combined buckle mechanism is applied to the installation of the sunroof assembly of the vehicle, a mounting hole is provided on the top of the vehicle body, and the combined buckle mechanism assembled with the buckle 1 and the positioning cylinder 2 is installed in the mounting hole, and the top plate of the vehicle body is located in the limiting space 26 between the elastic clamp arm 12 and the limiting plate 243, so that the combined buckle mechanism will not fall off from the mounting hole; the conical cylinder 23 extends from the mounting hole, and then in the process of installing the sunroof assembly on the vehicle body, the conical cylinder 23 is inserted into the positioning hole of the sunroof assembly, so that the combined buckle mechanism has the function of positioning and guiding; and the sunroof assembly can be clamped by the elastic clamp arm 12, so that the combined buckle mechanism has the function of pre-hanging. In the utility model, the combined buckle mechanism has the functions of positioning and pre-hanging, and the combined buckle mechanism can be installed on the vehicle body in only one mounting hole, and the demand for the vehicle body installation space is small, which ensures the stability of the assembly between the sunroof assembly and the vehicle body, and improves the convenience of installing the sunroof assembly on the vehicle body, and reduces the assembly cost of the sunroof assembly. In addition, the elastic clamping arm 12 can also play the role of pre-hanging the awning sunshade.
