Description

Technical Field

[0001] This invention relates to the field of fastener technology, and more specifically to a buckle and automotive trim component. Background Technology

[0002] In the fixing of automotive parts, snap-fit ​​couplings are the most common method. A typical snap-fit ​​consists of a female and a male clip. The female clip is inserted into the female clip via a snap-fit ​​or threaded connection to secure the two parts. However, existing snap-fit ​​couplings require the disassembly direction to be opposite to the installation direction, which can easily damage the coupling's structure and reduce the number of times it can be reused. Summary of the Invention

[0003] The purpose of this invention is to provide a buckle and a car trim component that can effectively solve the problem of damage during disassembly and increase the number of times the buckle can be reused.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A buckle for assembling a component to be assembled, the component having a fixing hole, the buckle comprising: a female buckle body having a through hole arranged along its own axial direction and a plurality of cantilever arms arranged around the through hole, the cantilever arms having a locking part on the side facing the through hole, the locking part dividing the through hole into a first space and a second space; and a male buckle body including a rod slidably disposed in the through hole, the rod having a first protrusion on its outer periphery, the male buckle body including an initial state in which the first protrusion is located in the first space, a locked state in which the first protrusion is located in the second space, and a disassembled state in which the first protrusion is located outside the through hole; wherein, when the male buckle body is in the locked state, the first protrusion supports the inner side of the cantilever arm so that the extension width of the cantilever arm is greater than the inner diameter of the fixing hole of the component to be assembled; when the male buckle body is in the initial state and the disassembled state, the extension width of the cantilever arm is less than the inner diameter of the fixing hole of the component to be assembled.

[0006] According to the above configuration, the rod of the buckle body slides from the first space to the second space. The first protrusion on the outer periphery of the rod supports the inner side of the cantilever and causes the cantilever to deform outward. The extension width of the cantilever is greater than the inner diameter of the fixing hole, thereby fixing the part to be installed. When disassembly is required, the rod continues to slide along the through hole, causing the first protrusion to slide away from the first space and slide out of the through hole. The cantilever returns to its original shape, and the extension width of the cantilever is less than the inner diameter of the fixing hole, thus separating the buckle from the part to be installed. This effectively solves the problem of damage during disassembly and increases the number of times the buckle can be reused.

[0007] Furthermore, the female buckle body also includes a female buckle end, one end of the cantilever is connected to the female buckle end, and the other end is a free end; wherein, when the male buckle body is in the locked state, the free end of the cantilever deforms in the direction away from the through hole, so that the cantilever and the female buckle end respectively abut against the two sides of the component to be installed, and the angle between the cantilever and the central axis of the female buckle body gradually decreases as the first protrusion moves in the direction away from the first space.

[0008] According to the above configuration, the cantilever of the female buckle body passes through the fixing hole of the component to be installed. The cantilever deforms outward, and the extension width of the cantilever is greater than the inner diameter of the fixing hole of the component to be installed. This allows the cantilever to abut against one side of the component to be installed, and the end of the female buckle to abut against the other side of the component to be installed, thereby completing the assembly and fixing of the two parts of the component to be installed. When disassembling the buckle, the male buckle body is pushed so that the first protrusion slides away from the first space. The opening angle of the cantilever gradually decreases until it returns to its original state. Therefore, there is no need to reverse the operation when disassembling, so as not to cause compression deformation to the buckle structure itself or the component to be installed, thus ensuring the number of times the buckle can be reused.

[0009] Furthermore, the through hole also includes a circular hole disposed in the middle of the female buckle end, the circular hole communicating with the first space; the male buckle body also includes a male buckle end disposed at the end of the rod body, the male buckle end being slidably disposed within the circular hole and the first space; wherein, when the male buckle body is in the initial state, the end of the male buckle end away from the rod body is located outside the through hole; when the male buckle body is in the disassembled state, the end of the rod body away from the male buckle end is located outside the through hole.

[0010] According to the above configuration, the end of the buckle slides within the circular hole and the first space. When the buckle body is in the initial state, the end of the buckle port is located outside the through hole, making it convenient to press the end of the buckle downward so that the first protrusion enters the second space through the locking part from the first space, completing the assembly and fixing of the component to be assembled. When the buckle is in the disassembled state, the end of the rod is located outside the through hole, making it convenient to press the end of the rod so that the buckle body slides in the opposite direction along the through hole, so that the first protrusion returns to the first space, restoring the initial state for easy use next time.

[0011] Furthermore, a sliding groove and a support groove communicating with the sliding groove are provided on the inner wall of the circular hole. The sliding groove is provided along the extension direction of the through hole, and a support surface is provided on the side of the support groove facing away from the clamping part. A limit slider is provided on the outer periphery of the sub-buckle end, and the limit slider can slide along the sliding groove. A rotating groove is provided on the end of the sub-buckle end away from the rod body. When the sub-buckle body is in the locked state, the limit slider abuts against the support surface of the support groove, and the first protrusion abuts against the side of the clamping part away from the support groove. When the sub-buckle body is in the disassembled state, the limit slider is located in the sliding groove, and a gap is left between the limit slider and the end of the sliding groove adjacent to the clamping part.

[0012] According to the above settings, when the buckle body is in the locked state, the limiting slider abuts against the support surface of the support groove to prevent the buckle body from sliding downward. At the same time, the first protrusion abuts against the locking part in the second space to prevent the first protrusion from sliding upward, thereby allowing the buckle body to remain in the locked state. When it is necessary to disassemble the buckle body, the buckle end is rotated at a certain angle into the sliding groove to release the downward limitation on the buckle body, allowing the buckle body to slide downward until the first protrusion slides out of the through hole. The cantilever returns to its original state, releasing the locking of the part to be installed, and the buckle can be disassembled. When the buckle body is in the disassembly state, there is a gap between the limiting slider and the bottom of the sliding groove, which ensures that the first protrusion can slide out of the through hole through the second space, while preventing the buckle body from disengaging from the through hole from below.

[0013] Furthermore, the support surface of the support groove is an inclined structure, and the height of the support surface gradually decreases from the end adjacent to the sliding groove to the end away from the sliding groove. The end of the limiting slider facing the support surface is an inclined structure that cooperates with the support surface.

[0014] According to the above configuration, the sliding groove is parallel to the axial direction of the through hole, and the support groove is arranged along the circumference of the through hole. One end of the support groove is connected to the sliding groove. By setting the support surface of the support groove and the bottom surface of the limiting slider as an inclined structure, when the buckle body is in the locked state, the support surface of the support groove and the bottom surface of the limiting slider abut against each other, preventing the buckle body from rotating and causing the limiting slider to rotate into the sliding groove, which can further ensure the locking effect of the buckle.

[0015] Furthermore, the female buckle body also includes a retainer connected to the end of the female buckle, the retainer being provided with a receiving hole for accommodating the cantilever, and a gap is left between the free end of the cantilever and the retainer to accommodate the first protrusion.

[0016] According to the above configuration, the cantilever is set in the receiving hole, with one end connected to the female buckle end and the other end being a free end. When the first protrusion supports the interior of the cantilever, the free end of the cantilever deforms outward, thereby locking the component to be installed. A gap is left between the free end of the cantilever and the retainer to ensure that the cantilever can deform under the squeezing action of the first protrusion. The entire female buckle body includes the female buckle end, the retainer, and the cantilever, further ensuring the overall stability of the female buckle body structure.

[0017] Furthermore, the first protrusion is provided with a first pressing slope on both sides along the axial direction of the rod body, and the clamping part is provided with a second pressing slope that cooperates with the first pressing slope on both sides along the axial direction of the through hole.

[0018] According to the above configuration, the first pressing slope on both sides of the first protrusion and the second pressing slope on both sides of the clamping part facilitate the first protrusion to slide along the axial direction of the through hole through the clamping part. When the buckle body is in the locked state, the first pressing slope above the first protrusion abuts against the second pressing slope at the bottom of the clamping part, which can further maintain the locked state of the buckle.

[0019] Furthermore, a limiting component is provided on the outer periphery of the rod body, which can engage with the locking part to keep the buckle body in its initial state.

[0020] According to the above settings, when the end of the rod is pressed and the sub-buckle body slides upward along the through hole, the limiting component on the rod engages with the locking part, so that the sub-buckle body is stably in the initial state, preventing the sub-buckle body from sliding upward and disengaging from the female buckle body, and avoiding the parts from being scattered and lost. At this time, the bottom of the rod body and the bottom of the female buckle body are in the same plane.

[0021] Furthermore, the limiting component includes a second protrusion and a third protrusion spaced apart along the axial direction of the rod, and a limiting groove is formed between the second protrusion and the third protrusion to engage with the locking part.

[0022] According to the above configuration, a limiting groove is formed between the second and third protrusions. The limiting groove engages with the locking part to temporarily fix the buckle body. Specifically, the diameters of the second and third protrusions are smaller than the diameter of the first protrusion and larger than the radial width of the locking part. The diameter of the limiting groove is equal to the radial width of the locking part. This ensures that the initial state of the buckle body is maintained and that the cantilever is in a non-stressed state when the buckle body is in its initial state, thus avoiding the cantilever being in an open state for a long time and affecting its performance in restoring its original state later.

[0023] A vehicle trim component includes a component to be installed, which includes a first component and a second component, each having a fixing hole; and the aforementioned buckle; the cantilever of the buckle passes through the fixing holes of the first and second components, and when the female buckle body is in a locked state, the cantilever of the female buckle body deforms outward to fix the first and second components.

[0024] According to the above configuration, the cantilever of the female buckle body passes through the fixing holes of the first and second components. The female buckle body slides along the through hole, and the first protrusion slides into the second space. The first protrusion supports the inner side of the cantilever and causes the cantilever to deform, so that the extension width of the cantilever is greater than the inner diameter of the fixing hole, thereby locking and fixing the first and second components. When it is necessary to disassemble the buckle, the female buckle body continues to slide, so that the first protrusion slides out of the through hole through the second space, and the cantilever returns to its original shape, thereby allowing the buckle to be separated from the component to be installed.

[0025] The beneficial effects of this invention are as follows: The rod of the buckle body slides from the first space to the second space. The first protrusion on the outer periphery of the rod supports the inner side of the cantilever and causes the cantilever to deform outward. The extension width of the cantilever is greater than the inner diameter of the fixing hole, thereby fixing the part to be installed. When disassembly is required, the rod continues to slide along the through hole, causing the first protrusion to slide away from the first space and slide out of the through hole. The cantilever returns to its original shape, and the extension width of the cantilever is less than the inner diameter of the fixing hole, thereby separating the buckle from the part to be installed. This effectively solves the problem of damage during disassembly and increases the number of times the buckle can be reused. Attached Figure Description

[0046] like Figure 1-13 As shown, this embodiment proposes a snap fastener for assembling a component 3 to be assembled. The component 3 has a fixing hole 33. The snap fastener includes a female snap fastener body 1 and a female snap fastener body 2, wherein:

[0047] The female buckle body 1 has a through hole 11 arranged along its own axis and a plurality of cantilever arms 12 arranged around the through hole 11. A clamping part 121 is provided on the side of the cantilever arm 12 facing the through hole 11, and the clamping part 121 divides the through hole 11 into a first space 111 and a second space 112.

[0048] The sub-buckle body 2 includes a rod 21 slidably disposed in the through hole 11. A first protrusion 211 is provided on the outer periphery of the rod 21. The sub-buckle body 2 includes an initial state in which the first protrusion 211 is located in the first space 111, a locked state in which the first protrusion 211 is located in the second space 112, and a disassembled state in which the first protrusion 211 is located outside the through hole 11.

[0049] When the buckle body 2 is in the locked state, the first protrusion 211 supports the inner side of the cantilever 12 so that the extension width of the cantilever 12 is greater than the inner diameter of the fixing hole 33 of the component to be installed; when the buckle body 2 is in the initial state and the disassembled state, the extension width of the cantilever 12 is less than the inner diameter of the fixing hole 33 of the component to be installed.

[0050] In this application, the rod 21 of the buckle body 2 slides from the first space 111 to the second space 112. The first protrusion 211 on the outer periphery of the rod 21 supports the inner side of the cantilever 12 and causes the cantilever 12 to deform outward. The extension width of the cantilever 12 is greater than the inner diameter of the fixing hole 33, thereby fixing the component 3 to be installed. When disassembly is required, the rod 21 continues to slide along the through hole 11, causing the first protrusion 211 to slide away from the first space 111 and slide out of the through hole 11. The cantilever 12 returns to its original state. The extension width of the cantilever 12 is less than the inner diameter of the fixing hole 33, thereby separating the buckle from the component 3 to be installed. This effectively solves the problem of damage during disassembly and increases the number of times the buckle can be reused.

[0051] In related technologies, the male and female buckles of a snap-fit ​​or latch are locked and fixed to the component 3 to be installed by means of threads or snap-fit. When the snap-fit ​​is disassembled, the male and female buckles need to be forcibly separated in opposite directions. During the forced separation process, the snap-fit ​​itself may be deformed or the fixing hole 33 of the component 3 to be installed may be squeezed and deformed, affecting the number of times the snap-fit ​​can be reused or damaging the component 3 to be installed. In this application, when the snap-fit ​​is disassembled, the male buckle body 2 continues to slide along the axial direction of the through hole 11 and slides in a direction away from the first space 111. During the sliding process, the opening angle of the cantilever 12 gradually decreases until the cantilever 12 returns to its original shape, so that there is no hard compression between the snap-fit ​​and the component 3 to be installed, thereby protecting the snap-fit ​​itself and the component 3 to be installed.

[0052] In some embodiments, the female buckle body 1 further includes a female buckle end 13, one end of the cantilever 12 is connected to the female buckle end 13, and the other end is a free end 122; wherein, when the male buckle body 2 is in the locked state, the free end 122 of the cantilever 12 deforms in the direction away from the through hole 11, so that the cantilever 12 and the female buckle end 13 respectively abut against the two sides of the component to be installed 3, and the angle between the cantilever 12 and the central axis of the female buckle body 1 gradually decreases as the first protrusion 211 moves in the direction away from the first space 111.

[0053] In this application, the cantilever 12 of the female buckle body 1 passes through the fixing hole 33 of the component to be installed 3. The cantilever 12 deforms outward, and the extension width of the cantilever 12 is greater than the inner diameter of the fixing hole 33 of the component to be installed 3. This allows the cantilever 12 to abut against one side of the component to be installed 3, and the female buckle end 13 to abut against the other side of the component to be installed 3, thereby completing the assembly and fixing of the two parts of the component to be installed 3. When the buckle is disassembled, the male buckle body 2 is pushed so that the first protrusion 211 slides away from the first space 111. The opening angle of the cantilever 12 gradually decreases until it returns to its original state. Therefore, there is no need to reverse the operation when disassembling, so as not to cause compression deformation to the buckle itself or the component to be installed 3, thus ensuring the number of times the buckle can be reused.

[0054] In some embodiments, the through hole 11 further includes a circular hole 113 disposed in the middle of the female buckle end 13, the circular hole 113 communicating with the first space 111; the female buckle body 2 further includes a female buckle end 22 disposed at the end of the rod body 21, the female buckle end 22 being slidably disposed in the circular hole 113 and the first space 111; wherein, when the female buckle body 2 is in the initial state, the end of the female buckle end 22 away from the rod body 21 is located outside the through hole 11; when the female buckle body 2 is in the disassembled state, the end of the rod body 21 away from the female buckle end 22 is located outside the through hole 11.

[0055] In this application, the sub-buckle end 22 slides within the circular hole 113 and the first space 111. When the sub-buckle body 2 is in the initial state, the end of the sub-buckle port is located outside the through hole 11, making it convenient to press the sub-buckle end 22 downward so that the first protrusion 211 enters the second space 112 through the locking part 121 from the first space 111, completing the assembly and fixing of the component 3 to be assembled. When the buckle is in the disassembled state, the end of the rod 21 is located outside the through hole 11, making it convenient to press the end of the rod 21 so that the sub-buckle body 2 slides in the opposite direction along the through hole 11, so that the first protrusion 211 returns to the first space 111, restoring the initial state for easy use next time.

[0056] Specifically, when the male buckle body 2 is in the locked state, the upper surface of the male buckle end 22 and the upper surface of the female buckle end 13 are in the same horizontal plane, so as to avoid the buckle having a protruding tip that could scratch clothing or the body.

[0057] In some embodiments, a sliding groove 131 and a support groove 132 communicating with the sliding groove 131 are provided on the inner sidewall of the circular hole 113. The sliding groove 131 is provided along the extension direction of the through hole 11, and a support surface 1321 is provided on the side of the support groove 132 facing away from the clamping part 121. A limiting slider 221 is provided on the outer periphery of the buckle end 22. The limiting slider 221 can slide along the sliding groove 131, and a rotating groove 222 is provided at the end of the buckle end 22 away from the rod body 21. When the buckle body 2 is in the locked state, the limiting slider 221 abuts against the support surface 1321 of the support groove 132, and the first protrusion 211 abuts against the side of the clamping part 121 away from the support groove 132. When the buckle body 2 is in the disassembled state, the limiting slider 221 is located in the sliding groove 131, and a gap is left between the limiting slider 221 and the end of the sliding groove 131 adjacent to the clamping part 121.

[0058] Specifically, the rotating groove 222 has a cross structure. The end of the cross top rod can be inserted into the rotating groove 222 to rotate the sub-buckle body 2. The limiting slider 221 of the sub-buckle body 2 is rotated into the sliding groove 131, and the sub-buckle body 2 can be pushed down to complete the disassembly of the buckle.

[0059] In this application, when the buckle body 2 is in the locked state, the limiting slider 221 abuts against the support surface 1321 of the support groove 132 to prevent the buckle body 2 from sliding downward. At the same time, the first protrusion 211 abuts against the locking part 121 in the second space 112 to prevent the first protrusion 211 from sliding upward, thereby allowing the buckle body 2 to remain in the locked state. When it is necessary to disassemble the buckle body 2, the buckle end 22 is rotated at a certain angle into the sliding groove 131 to release the downward limitation on the buckle body 2, allowing the buckle body 2 to slide downward until the first protrusion 211 slides out of the through hole 11. The cantilever 12 returns to its original state, releasing the locking of the component 3 to be installed, and the buckle can be disassembled. When the buckle body 2 is in the disassembled state, there is a gap between the limiting slider 221 and the bottom of the sliding groove 131, which ensures that the first protrusion 211 can slide out of the through hole 11 through the second space 112, and also prevents the buckle body 2 from disengaging from below the through hole 11.

[0060] Optionally, when the buckle body 2 is in the disassembled state, the first protrusion 211 is located outside the through hole 11, and the limiting slider 221 can also contact the bottom of the sliding groove 131. This can also ensure that the first protrusion 211 can slide out of the through hole 11 through the second space 112, and prevent the buckle body 2 from disengaging from the through hole 11 from below.

[0061] In some embodiments, the support surface 1321 of the support groove 132 is an inclined structure, and the height of the support surface 1321 gradually decreases from one end adjacent to the sliding groove 131 to the end away from the sliding groove 131. The end of the limiting slider 221 facing the support surface 1321 is an inclined structure that cooperates with the support surface 1321.

[0062] In this application, the sliding groove 131 is parallel to the axial direction of the through hole 11, and the support groove 132 is arranged along the circumference of the through hole 11. One end of the support groove 132 is connected to the sliding groove 131. By setting the support surface 1321 of the support groove 132 and the bottom surface of the limiting slider 221 as an inclined structure, when the buckle body 2 is in the locked state, the support surface 1321 of the support groove 132 and the bottom surface of the limiting slider 221 abut against each other, preventing the buckle body 2 from rotating and causing the limiting slider 221 to rotate into the sliding groove 131. In some embodiments, the locking effect of the buckle can be guaranteed.

[0063] Specifically, the first protrusion 211 abuts against the locking part 121, and the cantilever 12 has an inward contraction force, which makes the buckle body 2 tend to move downward. The support surface 1321 and the limiting slider 221 cooperate through the inclined structure, so that the limiting slider 221 can be stably placed on the support surface 1321, and the limiting slider 221 will not rotate with the buckle body 2.

[0064] In some embodiments, the female buckle body 1 further includes a retainer 14 connected to the female buckle end 13. The retainer 14 is provided with a receiving hole 141 for receiving the cantilever 12, and a gap is left between the free end 122 of the cantilever 12 and the retainer 14 to receive the first protrusion 211.

[0065] In this application, the cantilever 12 is disposed in the receiving hole 141, one end is connected to the female buckle end 13, and the other end is the free end 122. When the first protrusion 211 supports the interior of the cantilever 12, the free end 122 of the cantilever 12 deforms outward, thereby locking the component 3 to be installed. A gap is left between the free end 122 of the cantilever 12 and the retainer 14 to ensure that the cantilever 12 can deform under the squeezing action of the first protrusion 211. The entire female buckle body 1 includes the female buckle end 13, the retainer 14 and the cantilever 12, which ensures the stability of the overall structure of the female buckle body 1 in some embodiments.

[0066] Specifically, the free end 122 of the cantilever 12 is provided with a first chamfer structure 123 on the side facing the through hole 11, so that the first protrusion 211 can enter the through hole 11 from the outside; the bottom of the outer periphery of the retainer 14 is provided with a second chamfer structure 142, so that the retainer 14 can be inserted into the fixing hole 33 of the component to be installed 3.

[0067] The retainer 14 can be a cylindrical structure or a square structure. When a cylindrical structure is used, the outer diameter of the retainer 14 should be smaller than the inner diameter of the fixing hole 33 of the component to be installed. When a square structure is used, the diagonal length of the retainer 14 should be smaller than the inner diameter of the fixing hole 33 of the component to be installed.

[0068] In some embodiments, the first protrusion 211 is provided with a first pressing slope 2111 on both sides along the axial direction of the rod 21, and the clamping part 121 is provided with a second pressing slope 1211 that cooperates with the first pressing slope 2111 on both sides along the axial direction of the through hole 11.

[0069] In this application, the first pressing slope 2111 on both sides of the first protrusion 211 and the second pressing slope 1211 on both sides of the locking part 121 facilitate the first protrusion 211 to slide along the axial direction of the through hole 11 through the locking part 121. When the buckle body 2 is in the locked state, the first pressing slope 2111 above the first protrusion 211 abuts against the second pressing slope 1211 at the bottom of the locking part 121, which can maintain the locked state of the buckle in some embodiments.

[0070] Specifically, the first pressing slope 2111 on both sides of the first protrusion 211 cooperates with the second pressing slope 1211 on both sides of the clamping part 121, which facilitates the passage of the first protrusion 211 through the clamping part 121, and the cooperation between the first pressing slope 2111 and the second pressing slope 1211 allows the buckle to remain in the locked state.

[0071] In some embodiments, a limiting component 212 is provided on the outer periphery of the rod 21. The limiting component 212 can engage with the locking part 121 to put the buckle body 2 in the initial state.

[0072] In this application, when the end of the rod 21 is pressed and the sub-buckle body 2 slides upward along the through hole 11, the limiting component 212 on the rod 21 engages with the locking part 121, so that the sub-buckle body 2 is stably in the initial state, preventing the sub-buckle body 2 from sliding upward and disengaging from the female buckle body 1, and avoiding the parts from being scattered and lost. At this time, the bottom of the rod 21 and the bottom of the female buckle body 1 are located in the same plane.

[0073] In some embodiments, the limiting component 212 includes a second protrusion 2121 and a third protrusion 2122 spaced apart along the axial direction of the rod 21, and a limiting groove 2123 is formed between the second protrusion 2121 and the third protrusion 2122 to engage with the locking portion 121.

[0074] In this application, a limiting groove 2123 is formed between the second protrusion 2121 and the third protrusion 2122. The limiting groove 2123 is engaged with the clamping part 121 to temporarily fix the sub-buckle body 2. Specifically, the diameter of the second protrusion 2121 and the third protrusion 2122 is smaller than the diameter of the first protrusion 211 and larger than the radial width of the engaging part. The diameter of the limiting groove 2123 is equal to the radial width of the engaging part. This can ensure that the initial state of the sub-buckle body 2 is maintained and that the cantilever 12 is in a non-stressed state when the sub-buckle body 2 is in the initial state, thus avoiding the cantilever 12 being in an open state for a long time and affecting its performance in restoring its original state later.

[0075] In this application, the buckle is normally in its initial state, with the free end 122 of the cantilever 12 in its initial state. When it is necessary to fix the component 3 to be installed, the cantilever 12 and the support frame of the female buckle body 1 are passed through the fixing hole 33 of the component 3 to be installed, and the female buckle end 13 abuts against one surface of the component 3 to be installed. By pressing the male buckle end 22, the male buckle body 2 slides along the through hole 11. The first protrusion 211 on the rod 21 passes through the locking part 121 and enters the second space 112. The first protrusion 211 supports the inner wall of the second space 112 (i.e., the inner side of the cantilever 12), causing the cantilever 12 to deform outward. When the cantilever 12 is opened, the width of the free end 122 is greater than the inner diameter of the fixing hole 33. The outer surface of the cantilever 12 abuts against the fixing hole 33, thereby forming a clamping effect with the female buckle end 13, completing the fixation of the component 3 to be installed. When it is necessary to disassemble the buckle, rotate the female buckle body 2 so that the limiting slider 221 rotates into the sliding groove 131. Continue to push the female buckle body 2 so that the first protrusion 211 slides out of the through hole 11. The cantilever 12 returns to its original state. The width of the free end 122 of the cantilever 12 is less than the inner diameter of the fixing hole 33, so the female buckle body 1 can be pulled out from the fixing hole 33 of the component 3 to be installed, completing the disassembly.

[0076] Figure 14 This diagram shows a cross-sectional view of a buckle provided in an embodiment of this application when the buckle body is in a locked state.

[0077] like Figure 14 As shown, this application embodiment provides a vehicle trim component, including a component 3 to be installed, the component 3 including a first component 31 and a second component 32, the first component 31 and the second component 32 respectively provided with fixing holes 33; and the aforementioned buckle; the cantilever 12 of the buckle passes through the fixing holes 33 of the first component 31 and the second component 32, when the female buckle body 2 of the buckle is in the locked state, the cantilever 12 of the female buckle body 1 deforms outward to fix the first component 31 and the second component 32.

[0078] In this application, the cantilever 12 of the female buckle body 1 passes through the fixing hole 33 of the first component 31 and the second component 32. The female buckle body 2 slides along the through hole 11, and the first protrusion 211 slides into the second space 112. The first protrusion 211 supports the inner side of the cantilever 12 and causes the cantilever 12 to deform, so that the extension width of the cantilever 12 is greater than the inner diameter of the fixing hole 33, thereby locking and fixing the first component 31 and the second component 32. When it is necessary to disassemble the buckle, the female buckle body 2 continues to slide, so that the first protrusion 211 slides out of the through hole 11 through the second space 112, and the cantilever 12 returns to its original shape, thereby allowing the buckle to be separated from the component 3 to be installed.
