[0033] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0034] The embodiment of the present application provides a female buckle for a buckle assembly, as shown in Figures 1-6, which comprises a cylindrical portion 102, an abutting portion 103, a first elastic flap portion 104 and a second elastic flap portion 105 which can jointly form a mounting cavity 101, the first elastic flap portion 104 and the second elastic flap portion 105 are both arranged at the top end of the cylindrical portion 102 and are located at the opposite two radial sides of the cylindrical portion 102 respectively, the abutting portion 103 is arranged at the top end of the cylindrical portion 102 and is distributed in the circumferential direction and is spaced from the first elastic flap portion 104 and the second elastic flap portion 105, and the first elastic flap portion 104 and the second elastic flap portion 105 are both provided with a clamping protrusion 106 for clamping with the buckle mounting member 3 under the cooperation of the abutting portion 103.

[0035] Specifically, the buckle assembly in the embodiment is used for being mounted on a buckle mounting member 3 of a vehicle and comprises a female buckle 1 and a male buckle 2, the buckle mounting member 3 can be selected as a sheet metal member, the buckle mounting member 3 is formed with a through mounting hole, the bottom of the first elastic flap portion 104 and the bottom of the second elastic flap portion 105 are connected together with the top of the cylindrical portion 102, the bottom of the first elastic flap portion 104 and the bottom of the second elastic flap portion 105 are both free ends, and force applied to the top of the first elastic flap portion 104 and the top of the second elastic flap portion 105 can make the top of the first elastic flap portion 104 and the top of the second elastic flap portion 105 deflect around the respective bottom;

[0036] When the first elastic flap portion 104 and the second elastic flap portion 105 are both in a natural state, the spacing between the outer wall of the first elastic flap portion 104 and the outer wall of the second elastic flap portion 105 is consistent with the inner diameter of the mounting hole.

[0037] When the female buckle 1 needs to be detached from the buckle mounting member 3, an installer first detaches the male buckle 2 of the buckle assembly from the female buckle 1, then applies force to the first elastic flap portion 104 and the second elastic flap portion 105 to make them close to each other until the clamping protrusions 106 of the first elastic flap portion 104 and the second elastic flap portion 105 are all folded into the mounting cavity 101, at this time, the clamping protrusions 106 are disconnected with the buckle mounting member 3, and then the installer takes out the female buckle 1 from the mounting hole of the buckle mounting member 3 from bottom to top (that is, the installer can apply force to the female buckle 1 from the front to take it out of the mounting hole of the buckle mounting member 3, wherein the front refers to the side on which the force receiving portion 112 and the handle portion 206 are located after the buckle assembly is mounted), since the clamping protrusions 106 are all folded into the mounting cavity 101 when the female buckle 1 is taken out, the female buckle 1 will not be in contact with the edge of the mounting hole, so the female buckle 1 will not be cut by the edge of the mounting hole, and the stability and reliability of subsequent disassembly will not be affected; the male buckle 2 can be separated from the female buckle 1, that is, the male buckle 2 can be disconnected with the buckle mounting member 3 alone, thereby eliminating the risk of degradation of the clamping performance of the buckle assembly. In addition, the buckle assembly in the embodiment also has the advantages of simple structure and convenience for the installer to quickly install or disassemble.

[0038] In one embodiment of the present application, as shown in FIGS. 1-3, the abutting portion 103 includes a first abutting body 107 and a second abutting body 108 located at opposite radial sides of the cylindrical portion 102, respectively, the circumferential two sides of the first abutting body 107 are spaced apart from the first elastic flap portion 104 and the second elastic flap portion 105, respectively, the circumferential two sides of the second abutting body 108 are spaced apart from the first elastic flap portion 104 and the second elastic flap portion 105, respectively, the top end of the first abutting body 107 and the second abutting body 108 are formed with a lower buckle segment 109 for abutting with the top surface of the buckle mounting piece 3, and the buckle protrusion 106 is formed with a support surface 110 for abutting with the bottom surface of the buckle mounting piece 3.

[0039] Specifically, the first abutting body 107, the second abutting body 108, the first elastic flap portion 104 and the second elastic flap portion 105 are all arc-shaped, the first abutting body 107 and the second abutting body 108 further include an arc segment 115, the lower end of the arc segment 115 is connected with the cylindrical portion 102, the lower buckle segment 109 is arranged at the upper end of the arc segment 115, and the arc segment 115 away from the arc wall of the mounting cavity 101 is a smooth arc wall, which avoids scratching the edge or hole wall of the mounting hole during the installation or dismounting of the female buckle 1, and is beneficial to improving the smoothness of the installation or dismounting of the female buckle 1. Further, the lower buckle segment 109 extends away from the mounting cavity 101 and bends towards the direction of the cylindrical portion 102, so as to limit the downward movement of the female buckle 1 relative to the buckle mounting piece 3; the support surface 110 abuts with the bottom surface of the buckle mounting piece 3, which can limit the upward movement of the female buckle 1 relative to the buckle mounting piece 3, so that the lower buckle segment 109 and the buckle protrusion 106 of the female buckle 1 in this embodiment jointly prevent the vertical movement of the female buckle 1 relative to the buckle mounting piece 3 after the installation is completed, thereby ensuring the connection stability of the female buckle 1 and the buckle mounting piece 3.

[0040] In one embodiment of the present application, as shown in FIG. 4, the support surface 110 gradually expands outward away from the mounting cavity 101 from top to bottom, which can make the first elastic flap portion 104 and the second elastic flap portion 105 close to or move away from each other by a smaller distance, so as to fold or extend the buckle protrusion 106 in or out of the mounting cavity 101, which is beneficial to improving the operation convenience of the installer; the above design can also make the buckle protrusion 106 and the buckle mounting piece 3 have a sufficient width of abutting surface, so as to ensure that the buckle protrusion 106 and the buckle mounting piece 3 can be stably buckled together, thereby avoiding the situation that the buckle protrusion 106 and the buckle mounting piece 3 are not stably buckled, which leads to the disconnection of the female buckle 1 from the buckle mounting piece 3.

[0041] In an embodiment of the present application, as shown in FIG. 4, the clamping protrusion 106 is further formed with an avoiding surface 111 below the supporting surface 110, which gradually expands outward from bottom to top and away from the installation cavity 101. Specifically, this design can effectively avoid the first elastic flap 104 and the second elastic flap 105 from being scratched by the edge of the installation hole during the process of approaching or moving away from each other, further avoiding the female buckle 1 from being scratched by the clasp mounting member 3 during the process of installation or disassembly, which affects the subsequent use or disassembly reliability of the female buckle 1. In addition, the above design is also beneficial to reduce the manufacturing material of the female buckle 1 and reduce the production and manufacturing cost of the clasp assembly.

[0042] In an embodiment of the present application, as shown in FIGS. 1-6, the first elastic flap 104 and the second elastic flap 105 each further include a force receiving portion 112 at the top end, and the vertical distance between the force receiving portion 112 and the clamping protrusion 106 is greater than the vertical distance between the lower buckle segment 109 and the clamping protrusion 106. Specifically, arranging the force receiving portion 112 at the top end of the first elastic flap 104 and the second elastic flap 105 not only facilitates the installer to easily pick up the female buckle 1 and apply force to the first elastic flap 104 and the second elastic flap 105, so that the top end of the first elastic flap 104 and the top end of the second elastic flap 105 are deflected relative to the respective bottom end, but also enables the installer to apply less force to make the first elastic flap 104 and the second elastic flap 105 have a larger deflection amplitude, which is a reasonable design and can further improve the use reliability of the female buckle 1.

[0043] In an embodiment of the present application, the force receiving portion 112 is L-shaped, which has a simple structure, is easy to produce and manufacture, and is also convenient for the installer to apply force to the first elastic flap 104 and the second elastic flap 105 from the opposite radial sides of the female buckle 1 to deform them, so that the female buckle 1 can be quickly pulled out of the installation hole. Further, the lowest position of the force receiving portion 112 is higher than the lowest position of the lower buckle segment 109, which can avoid the bottom end of the force receiving portion 112 being too close to the clasp mounting member 3 and being inconvenient for the installer to apply force, and is beneficial to improve the use experience of the clasp assembly.

[0044] Another embodiment of the present application provides a clasp assembly, as shown in FIGS. 7-12, which includes the female buckle 1 for the clasp assembly described above and a male buckle 2 inserted into the installation cavity 101 and detachably connected with the cylindrical portion 102.

[0045] Further, the inner diameter of the mounting cavity 101 in the embodiment is greater than the diameter of the cylindrical portion 202 of the female buckle 2, and even when the female buckle 1 and the male buckle 2 are in an assembled state, the first elastic flap portion 104 and the second elastic flap portion 105 of the female buckle 1 still have sufficient retraction space, so when the buckle assembly is first installed, the installer can first assemble the male buckle 2 and the female buckle 1 together, then align the combined buckle assembly with the mounting hole of the buckle mounting member 3, and then push the buckle assembly from top to bottom until the clamping protrusion 106 is located below the buckle mounting member 3 and is completely ejected. During the above process, the female buckle 1 will not be scratched due to assembly interference.

[0046] When the buckle assembly and the buckle mounting member 3 are first disassembled, the installer removes the male buckle 2 together with other vehicle parts from the female buckle 1, and the female buckle 1 is still installed with the buckle mounting member 3. This can avoid the need to reinstall the female buckle 1 during the subsequent installation of the buckle assembly, and only needs to reinstall the male buckle 2 together with other parts on the female buckle 1. In the present application, the female buckle 1 and the male buckle 2 are both plastic parts, so there is no problem of scratching when they contact each other during installation.

[0047] In an embodiment of the present application, as shown in FIGS. 2-3 and 7-12, the cylindrical portion 102 is formed with a contraction section 113 at the bottom end, which gradually contracts radially inward from top to bottom. The bottom end of the male buckle 2 is formed with an annular clamping space 201 for the bottom end of the contraction section 113.

[0048] Specifically, the cylindrical portion 102 further includes a cylindrical section 116, the top of which is connected with the first abutting body 107, the second abutting body 108, the first elastic flap portion 104 and the second elastic flap portion 105, and the bottom of which is connected with the top of the contraction section 113. The annular clamping space 201 is formed on the outer peripheral wall of the bottom end of the male buckle 2. When the male buckle 2 needs to be installed on the female buckle 1, the installer holds the top end of the male buckle 2 and passes the male buckle 2 downward through the mounting cavity 101 of the female buckle 1 until the bottom end of the contraction section 113 of the female buckle 1 is clamped into the annular clamping space 201 of the male buckle 2, at which time the male buckle 2 and the female buckle 1 are installed together. When the male buckle 2 needs to be removed from the female buckle 1, the installer exerts force on the top end of the male buckle 2 to pull it upward until the contraction section 113 of the female buckle 1 is disengaged from the annular clamping space 201 of the male buckle 2, and then the male buckle 2 is separated from the mounting cavity 101 of the female buckle 1, at which time the male buckle 2 is completely removed.

[0049] In an embodiment of the present application, as shown in FIG. 8 and FIG. 11, the sub buckle 2 further comprises a columnar portion 202, a connecting portion 203, a clamping protrusion 204 and a pressing portion 205, the clamping protrusion 204 is arranged at the bottom end of the columnar portion 202, the connecting portion 203 is arranged below the clamping protrusion 204 and forms a ring-shaped clamping space 201 together with the clamping protrusion 204, the pressing portion 205 is arranged on the columnar portion 202 and is spaced apart from the clamping protrusion 204, the bottom surface of the pressing portion 205 is used to abut against the top surface of the buckle mounting member 3, and the shrinkable section 113 is formed with a clamping groove 114 which is recessed from bottom to top and can accommodate the clamping protrusion 204.

[0050] Specifically, the ring-shaped clamping space 201 is formed at the position where the connecting portion 203 and the clamping protrusion 204 are connected, and the connecting portion 203 can be in the shape of an inverted cone or an inverted truncated cone. The above arrangement makes the connecting portion 203 have a guiding surface which gradually expands outward from bottom to top, so that the sub buckle 2 can pass through the mounting cavity 101 from top to bottom to reach below the shrinkable section 113, and then the bottom end of the shrinkable section 113 can be clamped into the ring-shaped clamping space 201 between the connecting portion 203 and the clamping protrusion 204. In this embodiment, the connecting portion 203 is preferably in the shape of an inverted truncated cone, which not only has an inclined guiding surface, but also avoids the bottom end of the connecting portion 203 being too sharp to reduce the convenience and safety of the connecting portion 203. Further, the clamping groove 114 in this embodiment also functions as a weakening groove, which facilitates the deformation of the shrinkable section 113 under the action of the sub buckle 2 and the radial outward expansion of the shrinkable section 113, thereby improving the convenience of installation of the sub buckle 2. After the installation of the sub buckle 2 is completed, rotating the sub buckle 2 can make the clamping protrusion 204 clamped into the clamping groove 114, which increases the difficulty of disengagement of the sub buckle 2 and the female buckle 1, and further ensures the connection stability of the sub buckle 2 and the female buckle 1.

[0051] In this embodiment, the cross section of the pressing portion 205 is in the shape of a bend, i.e. the radial edge portion of the pressing portion 205 is bent downward and gradually expands outward from top to bottom, so as to abut against the top surface of the buckle mounting member 3, and can also be adapted to buckle mounting members 3 of different thicknesses. After the bottom end of the shrinkable section 113 is clamped into the ring-shaped clamping space 201, the clamping protrusion 204 is also clamped into the clamping groove 114, and the pressing portion 205 can limit the downward movement of the sub buckle 2 relative to the female buckle 1. The bottom of the shrinkable section 113 abutting against the top of the connecting portion 203 can limit the upward movement of the pressing portion 205 relative to the female buckle 1. Therefore, the clamping protrusion 204 and the pressing portion 205 can jointly further limit the vertical movement of the sub buckle 2 relative to the female buckle 1 after the installation is completed, thereby further improving the installation and connection stability of the sub buckle 2 and the female buckle 1.

[0052] In addition, the plurality of clamping protrusions 204 are evenly distributed in the circumferential direction of the columnar portion 202, and the number of the clamping grooves 114 is consistent with the number of the clamping protrusions 204, and the positions of the clamping grooves 114 correspond to the positions of the clamping protrusions 204 one by one, so that each clamping protrusion 204 can be clamped into the corresponding clamping groove 114, and when one or a few of the clamping protrusions 204 are damaged, the undamaged clamping protrusions 204 can still cooperate with the clamping grooves 114 to prevent the gap between the female buckle 1 and the male buckle 2 from being formed and the male buckle 2 from moving.

[0053] In the embodiment, the clamping force between the male buckle 2 and the female buckle 1 is smaller than the clamping force between the female buckle 1 and the clamping buckle mounting member 3, so as to ensure that the male buckle 2 can be smoothly separated from the female buckle 1 during disassembly, and the female buckle 1 still cooperates with the clamping buckle mounting member 3, thereby providing a protection function for subsequent multiple assembly and disassembly.

[0054] In an embodiment of the present application, as shown in FIGS. 8-12, the male buckle 2 further comprises a handle portion 206 arranged at the top end of the columnar portion 202. Specifically, the shape of the handle portion 206 is not limited in the embodiment and can be disc-shaped, quadrangular, hexagonal or other shapes. The handle portion 206 is vertically spaced from the pressing portion 205, and the arrangement facilitates the installer to apply force (such as manual force or force applied by a crowbar) to the handle portion 206, that is, the installer can install the male buckle 2 on the female buckle 1 through the handle portion 206, or pull the handle portion 206 upward to take the male buckle 2 out of the female buckle 1, and the arrangement of the handle portion 206 improves the convenience of use of the male buckle 2 and the clamping buckle assembly.
