[0027] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0028] Refer to Figures 1 - 3 Describe the snap structure 100 according to the embodiments of the present invention.

[0029] As Figures 1 - 3 shown, the snap structure 100 according to the embodiments of the present invention includes: a snap body 1 and a fitting member 3.

[0030] The snap body 1 has a first mating part 11, and the first mating part 11 is adapted to be anti-rotationally mated with the second mating part 21 of the first mounting member 2; the fitting member 3 is connected to the snap body 1, and the fitting member 3 is adapted to pass through the first mating hole 41 of the second mounting member 4 and is adapted to be anti-rotationally mated with the first mating hole 41. The fitting member 3 has a first mounting hole 35, at least part of the first mounting hole 35 is configured as a threaded hole, and the fitting member 3 is adapted to be abutted and limited against the surface of the second mounting member 4 away from the first mounting member 2.

[0031] Among them, the snap body 1 has a first mating part 11, the first mounting member 2 has a second mating part 21, and the first mating part 11 can be anti-rotationally mated with the second mating part 21 to reduce the probability of the first mounting member 2 rotating relative to the snap body 1.

[0032] The fitting member 3 is connected to the snap body 1. The connection manner between the fitting member 3 and the snap body 1 can be, but is not limited to, welding, bolt connection, etc. As some embodiments of the present application, the fitting member 3 and the snap body 1 are connected by welding, or the fitting member 3 and the snap body 1 are integrally formed.

[0033] The second mounting member 4 has a first mating hole 41. The mating member 3 can pass through the first mating hole 41 of the second mounting member 4, and the mating member 3 can be anti-rotationally mated with the first mating hole 41. That is to say, the snap structure 100 can be anti-rotationally mated with the second mounting member 4 to reduce the probability of the snap structure 100 rotating relative to the second mounting member 4.

[0034] The mating member 3 has a first mounting hole 35, and at least a part of the first mounting hole 35 is configured as a threaded hole. That is to say, a part of the first mounting hole 35 is configured as a threaded hole, or the entire first mounting hole 35 is configured as a threaded hole. And the mating member 3 can be abutted and limited against the surface of the second mounting member 4 away from the first mounting member 2. It should be noted that during the process of the mating member 3 extending into the first mating hole 41 of the second mounting member 4, a part of the structure of the mating member 3 abuts against the inner wall of the first mating hole 41, and a part of the structure of the mating member 3 will undergo elastic deformation so that the mating member 3 can be smoothly inserted into the first mating hole 41. When a part of the structure of the mating member 3 is separated from the inner wall of the first mating hole 41, a part of the structure of the mating member 3 will rebound and reset, so that the mating member 3 can be abutted and limited against the surface of the second mounting member 4 away from the first mounting member 2 to reduce the probability of the snap structure 100 being separated from the second mounting member 4.

[0035] As some embodiments of the present application, the first mounting member 2 has a second mounting hole 22, and the second mounting hole 22 is correspondingly arranged with the first mounting hole 35.

[0036] As some embodiments of the present application, when it is necessary to fix the first mounting member 2 to the second mounting member 4, the mating member 3 of the snap structure 100 can be first passed through the first mating hole 41 of the second mounting member 4. During the process of passing the mating member 3 through the first mating hole 41 of the second mounting member 4, a part of the structure of the mating member 3 abuts against the inner wall of the first mating hole 41, and a part of the structure of the mating member 3 will undergo elastic deformation so that the mating member 3 can be smoothly inserted into the first mating hole 41. When a part of the structure of the mating member 3 is separated from the inner wall of the first mating hole 41, a part of the structure of the mating member 3 will rebound and reset, so that the mating member 3 can be abutted and limited against the surface of the second mounting member 4 away from the first mounting member 2 to reduce the probability of the snap structure 100 being separated from the second mounting member 4. Then, the second mating portion 21 of the first mounting member 2 can be anti-rotationally mated with the first mating portion 11 of the snap structure 100. Then, a bolt can be passed through the second mounting hole 22 of the first mounting member 2 and the first mounting hole 35 of the mating member 3, and the bolt can be screwed with the internal thread of the first mounting hole 35 to mount the first mounting member 2 and the second mounting member 4 together.

[0037] Thus, by making the buckle structure 100 have a first engaging portion 11 adapted to non-rotatably engage with the second engaging portion 21 of the first mounting member 2 and making the buckle structure 100 have a fitting member 3 adapted to non-rotatably engage with the first fitting hole 41 of the second mounting member 4, the probability of the first mounting member 2 rotating during the tightening process can be reduced. By making at least part of the first mounting hole 35 configured as a threaded hole, the buckle structure 100 has the function of providing a tightening position, thereby improving the reliability of the buckle structure 100 and being beneficial to improving the assembly efficiency.

[0038] In some embodiments of the present invention, such as Figure 1 shown, the first engaging portion 11 is configured as one of a fitting protrusion and a second fitting hole, and the second engaging portion 21 is configured as the other of the fitting protrusion and the second fitting hole, and the fitting protrusion non-rotatably engages with the second fitting hole.

[0039] Among them, the first engaging portion 11 is configured as one of a fitting protrusion and a second fitting hole, and the second engaging portion 21 is configured as the other of the fitting protrusion and the second fitting hole. The fitting protrusion and the second fitting hole cooperate with each other so that the first mounting member 2 cannot rotate relative to the buckle body 1. As some embodiments of the present application, the first engaging portion 11 is configured as a second fitting hole, and the second engaging portion 21 is configured as a fitting protrusion. As some embodiments of the present application, the first engaging portion 11 is configured as a fitting protrusion, and the second engaging portion 21 is configured as a second fitting hole.

[0040] By making the first engaging portion 11 configured as one of a fitting protrusion and a second fitting hole and the second engaging portion 21 configured as the other of the fitting protrusion and the second fitting hole, the processing difficulty of the first engaging portion 11 and the second engaging portion 21 can be reduced. Moreover, the cooperation form of the fitting protrusion and the second fitting hole is reliable, and the fitting protrusion and the second fitting hole are simple to process.

[0041] In some embodiments of the present invention, such as Figure 1 and Figure 2 shown, the number of the first engaging portions 11 is multiple. In a plane perpendicular to the axial direction of the first mounting hole 35, the orthographic projections of the multiple first engaging portions 11 surround the orthographic projection of the fitting member 3.

[0042] Among them, the number of the first engaging portions 11 is multiple. The number of the first engaging portions 11 can be but is not limited to two, three, four, etc. As some embodiments of the present application, the number of the first engaging portions 11 is two. In a plane perpendicular to the axial direction of the first mounting hole 35, the orthographic projections of the multiple first engaging portions 11 surround the orthographic projection of the fitting member 3. It should be noted that a plane is set, and this plane is perpendicular to the axial direction of the first mounting hole 35 (i.e., Figure 2 the X direction shown), that is to say, the normal line of this plane is in the axial direction of the first mounting hole 35 (i.e.,Figure 2 parallel to the X direction shown, the orthographic projections of the multiple first engaging portions 11 on this plane surround the orthographic projection of the engaging member 3 on this plane. In other words, the multiple first engaging portions 11 are arranged around the central axis of the first mounting hole 35.

[0043] By making the number of the first engaging portions 11 be multiple and making the orthographic projections of the multiple first engaging portions 11 surround the orthographic projection of the engaging member 3, the snap structure 100 can be reasonably designed, and the anti-rotation effect between the snap structure 100 and the first mounting member 2 can be made more reliable.

[0044] In some embodiments of the present utility model, as Figure 1 shown, the engaging member 3 has multiple engaging surfaces 31 connected in sequence, and there is an included angle between every two adjacent engaging surfaces 31. The multiple engaging surfaces 31 are all suitable for anti-rotation engagement with the inner wall surface of the first engaging hole 41.

[0045] Among them, the engaging member 3 has the engaging surfaces 31, the number of the engaging surfaces 31 is multiple, and the number of the engaging surfaces 31 can be but is not limited to six, eight, ten, etc. As some embodiments of the present application, the number of the engaging surfaces 31 is six, and the six engaging surfaces 31 are connected in sequence. There is an included angle between every two adjacent engaging surfaces 31, and the included angle can be but is not limited to 60°, 45°, 36°, etc. As some embodiments of the present application, the included angle can be 60°. Specifically, the cross-section of the engaging member 3 can be configured as a regular hexagon.

[0046] The multiple engaging surfaces 31 can all be in anti-rotation engagement with the inner wall surface of the first engaging hole 41. That is to say, the inner wall surface of the first engaging hole 41 is adapted to the multiple engaging surfaces 31. It can be understood that the engaging member 3 can be inserted through the first engaging hole 41. When the engaging member 3 of the snap structure 100 is inserted into the first engaging hole 41, due to the multiple engaging surfaces 31 being connected in sequence and having an included angle, when the engaging member 3 has a tendency to rotate relative to the second mounting member 4, the inner wall surface of the first engaging hole 41 can limit the rotation of the engaging member 3.

[0047] By making the multiple engaging surfaces 31 be connected in sequence and have an included angle, the engaging member 3 can be reliably in anti-rotation engagement with the first engaging hole 41 of the second mounting member 4, so as to reduce the probability of the snap structure 100 rotating relative to the second mounting member 4.

[0048] In some embodiments of the present utility model, as Figures 1 - 3 shown, from the end of the engaging member 3 close to the snap body 1 to the end far from the snap body 1, at least part of the engaging surface 31 gradually approaches the axis of the first mounting hole 35.

[0049] Among them, along the axis direction of the first mounting hole 35 (i.e., Figure 2in the X direction shown, and from one end of the fitting 3 close to the buckle body 1 to the end far from the buckle body 1, at least part of the mating surface 31 gradually approaches the axis of the first mounting hole 35, that is to say, a part of the mating surface 31 gradually approaches the axis of the first mounting hole 35, or all of the mating surface 31 gradually approaches the axis of the first mounting hole 35. As some embodiments of the present application, along the axial direction of the first mounting hole 35 (i.e., Figure 2 in the X direction shown, and from one end of the fitting 3 close to the buckle body 1 to the end far from the buckle body 1, the lower part of the mating surface 31 gradually approaches the axis of the first mounting hole 35.

[0050] By making at least part of the mating surface 31 gradually approach the axis of the first mounting hole 35, the mating surface 31 of this part can have a guiding effect, so that it is convenient to pass the fitting 3 through the first fitting hole 41 of the second mounting member 4, which is beneficial to reducing the assembly difficulty and improving the assembly efficiency.

[0051] In some embodiments of the present invention, as Figure 2 shown, the buckle body 1 and the fitting 3 jointly define a clamping space 5, and the clamping space 5 is adapted to accommodate a part of the structure of the second mounting member 4.

[0052] As some embodiments of the present application, during the process of the fitting 3 extending into the first fitting hole 41 of the second mounting member 4, the mating surface 31 of the fitting 3 abuts against the inner wall of the first fitting hole 41, and the fitting 3 will undergo elastic deformation so that the fitting 3 can be smoothly inserted into the first fitting hole 41. When the fitting 3 is separated from the inner wall of the first fitting hole 41, the fitting 3 will rebound and reset. At this time, the clamping space 5 jointly defined by the buckle body 1 and the fitting 3 can accommodate a part of the structure of the second mounting member 4, and the rebounding part can abut against the surface of the second mounting member 4 far from the first mounting member 2.

[0053] By making the buckle body 1 and the fitting 3 jointly define a clamping space 5 and enabling the clamping space 5 to accommodate a part of the structure of the second mounting member 4, the buckle structure 100 can be reasonably designed, and the probability of separation between the buckle structure 100 and the second mounting member 4 during the assembly process can be reduced.

[0054] In some embodiments of the present invention, as Figure 1 shown, the fitting 3 has a weakening groove 34, and the weakening groove 34 is recessed in a direction perpendicular to the axial direction of the first mounting hole 35 (i.e., Figure 2 in the X direction shown).

[0055] Among them, the fitting 3 has a weakening groove 34. As some embodiments of the present application, the weakening groove 34 can be provided on the surface of any one of the plurality of mating surfaces 31, and the weakening groove 34 is along the axial direction of the first mounting hole 35 (i.e.,Figure 2 depressed in a direction perpendicular to the X direction shown.

[0056] It can be understood that during the process of the fitting member 3 extending into the first fitting hole 41 of the second mounting member 4, a part of the structure of the fitting member 3 (such as the side wall of the weakening groove 34) abuts against the inner wall of the first fitting hole 41, and the side wall of the weakening groove 34 can move (elastically deform) towards the inside of the weakening groove 34 so that the fitting member 3 can be smoothly inserted into the first fitting hole 41. When a part of the structure of the fitting member 3 (such as the side wall of the weakening groove 34) separates from the inner wall of the first fitting hole 41, a part of the structure of the fitting member 3 (such as the side wall of the weakening groove 34) will rebound and reset, and moreover, a part of the structure of the fitting member 3 (such as the side wall of the weakening groove 34) can abut against and limit the position of the surface of the second mounting member 4 away from the first mounting member 2, so as to reduce the probability of the snap structure 100 separating from the second mounting member 4.

[0057] By providing the fitting member 3 with the weakening groove 34, it is convenient for a part of the structure of the fitting member 3 (such as the side wall of the weakening groove 34) to undergo elastic deformation, so that the structural form of the fitting member 3 is reasonable, which is beneficial to improving the use reliability of the snap structure 100.

[0058] In some embodiments of the present invention, the fitting member 3 includes a fitting body 32 and a limiting hook, and the limiting hook is connected to the fitting body 32 and is adapted to abut against and limit the position of the surface of the second mounting member 4 away from the first mounting member 2.

[0059] Wherein, the fitting member 3 includes a fitting body 32 and a limiting hook, and the limiting hook is connected to the fitting body 32. The connection manner between the limiting hook and the fitting body 32 can be, but is not limited to, welding, snap connection, etc. As some embodiments of the present application, the limiting hook and the fitting body 32 are integrally formed, and moreover, the limiting hook can abut against and limit the position of the surface of the second mounting member 4 away from the first mounting member 2.

[0060] As some embodiments of the present application, one end of the limiting hook is connected to the fitting body 32, and moreover, along the axial direction of the first mounting hole 35 (i.e., Figure 2in the X direction shown, and from the end of the fitting 3 close to the buckle body 1 to the end far from the buckle body 1, the limiting hook gradually approaches the axis of the first mounting hole 35. During the process of the fitting 3 extending into the first fitting hole 41 of the second mounting member 4, a part of the structure of the fitting 3 (such as the limiting hook) abuts against the inner wall of the first fitting hole 41, and the side wall of the weakening groove 34 can move towards the inside of the weakening groove 34 (elastic deformation) so that the fitting 3 can be smoothly inserted into the first fitting hole 41. When a part of the structure of the fitting 3 (such as the limiting hook) is separated from the inner wall of the first fitting hole 41, a part of the structure of the fitting 3 (such as the limiting hook) will rebound and reset, and, a part of the structure of the fitting 3 (such as the limiting hook) can abut against and limit the surface of the second mounting member 4 far from the first mounting member 2, so as to reduce the probability of the separation of the buckle structure 100 from the second mounting member 4.

[0061] It can be understood that the buckle body 1 and the limiting hook can jointly define a clamping space 5.

[0062] By making the fitting 3 include a fitting body 32 and a limiting hook, and enabling the limiting hook to abut against and limit the surface of the second mounting member 4 far from the first mounting member 2, the probability of the separation of the buckle structure 100 from the second mounting member 4 during the assembly process can be reduced, which is beneficial to the use reliability of the buckle structure 100.

[0063] In some embodiments of the present invention, the buckle body 1 and the fitting 3 are integrally formed.

[0064] Among them, the buckle body 1 and the fitting 3 are integrally formed, that is to say, the buckle body 1 and the fitting 3 are constructed as an integrally formed part. The integrally formed part has high structural strength. By making the buckle body 1 and the fitting 3 integrally formed, the connection reliability between the buckle body 1 and the fitting 3 can be improved, and the probability of the breakage at the connection between the buckle body 1 and the fitting 3 can be reduced.

[0065] The vehicle according to the embodiment of the present invention includes the buckle structure 100 in the above embodiment. By making the buckle structure 100 have a first fitting portion 11 adapted to be anti-rotationally fitted with the second fitting portion 21 of the first mounting member 2, and making the buckle structure 100 have a fitting 3 adapted to be anti-rotationally fitted with the first fitting hole 41 of the second mounting member 4, the probability of the rotation of the first mounting member 2 during the tightening process can be reduced. By making at least part of the first mounting hole 35 be constructed as a threaded hole, the buckle structure 100 has the function of providing a tightening position, so that the use reliability of the buckle structure 100 can be improved, which is beneficial to improving the assembly efficiency.
