Description

Technical Field

[0001] This application relates to the technical field related to the connection of vehicle interiors, and particularly to a snap fastener and a vehicle. Background Art

[0002] Snap fasteners are mainly used for connecting plastic trim parts and sheet metal on vehicles. The common connection method between plastic trim parts and sheet metal is to complete the fixation through screws or bolts. When using screws or bolts for connection, there is a high installation strength, which can effectively ensure the stability and reliability of the connection between the connected parts. However, the installation process of this connection method is relatively complex, and both installation and disassembly take a long time, resulting in high costs. Currently, snap fasteners are commonly used to replace screws or bolts for the fixed connection of plastic trim parts and sheet metal. However, when some existing snap fasteners are used to fixedly connect vehicle parts, the structure needs to be deformed. A structure that is deformed for a long time is prone to aging and cracking, resulting in the failure of fixation, and the reuse rate is low. Summary of the Utility Model

[0003] Based on this, it is necessary to provide a snap fastener that is simple to install, not easily broken, and can be reused.

[0004] To solve the above technical problems, the present application provides the following technical solutions:

[0005] A snap fastener for connecting a plastic trim part and a sheet metal, the snap fastener comprising: a female snap for connecting the sheet metal, and an elastic piece is provided on the female snap, and the elastic piece can pass through the sheet metal under the drive of the female snap and abut against the sheet metal; a male snap for connecting the plastic trim part, and the male snap can be inserted into the female snap and be snap-fitted with the female snap.

[0006] It can be understood that in the present application, by providing a female snap and a male snap, with an elastic piece provided on the female snap, after the elastic piece on the female snap passes through the sheet metal driven by the female snap, the elastic piece on the female snap can abut against the sheet metal, and then the male snap is inserted into the female snap, and the male snap and the female snap are snap-fitted to complete the connection and fixation of the plastic trim part and the sheet metal. In this way, only the cooperation of the female snap and the male snap is required for fixed connection, and during disassembly, only the male snap needs to be removed to complete disassembly. The installation is simple and time-consuming, and it is convenient for disassembly; at the same time, when the snap fastener is used for the fixed connection of vehicle trim and sheet metal, no deformation will occur, so it is not easily broken and aged, and the reuse rate is relatively high.

[0007] In one embodiment, the elastic piece is provided with convex ribs, and the convex ribs can be snap-fitted to the male snap on the female snap to limit the deformation of the elastic piece towards the axis of the female snap.

[0008] It can be understood that when the male snap is inserted through the convex ribs of the female snap, the convex ribs can abut against the male snap, so as to inhibit the deformation of the elastic piece towards the axis direction of the female snap, and further make the structure of the female snap not easily deformed and broken, improving the connection stability of the snap fastener structure.

[0009] In one embodiment, the number of the elastic pieces is configured to be multiple, and the multiple elastic pieces are arranged at intervals along the circumferential direction of the female buckle.

[0010] It can be understood that setting multiple elastic pieces can increase the abutting force of the elastic piece structure on the sheet metal, thereby increasing the stability of the elastic piece on the sheet metal fixing structure. At the same time, using multiple elastic pieces arranged at intervals in the circumferential direction to abut against the sheet metal part makes the female buckle and the sheet metal part have multiple acting positions when the female buckle is connected to the sheet metal part, which can improve the stability of the female buckle when connected to the sheet metal part.

[0011] In one embodiment, a guiding inclined surface is formed on the elastic piece, and the guiding inclined surface is used to guide the elastic piece to pass through the sheet metal.

[0012] It can be understood that during the movement of the female buckle inserted into the sheet metal, the sheet metal can always fit against the guiding inclined surface, thereby guiding the elastic piece to pass through the sheet metal, enabling the female buckle to pass through the sheet metal and completing the clamping of the female buckle to the sheet metal.

[0013] In one embodiment, an abutting surface is further formed on the elastic piece, and the abutting surface can abut against the sheet metal to limit the female buckle to the sheet metal.

[0014] In one embodiment, a plurality of claws are provided on the male buckle, and the plurality of claws can be respectively clamped with the female buckle; wherein, the plurality of claws are arranged at intervals along the circumferential direction of the male buckle.

[0015] It can be understood that setting the claws can fix the male buckle to the female buckle during the clamping process of the male and female buckles, preventing the male buckle from falling off the female buckle. Moreover, the plurality of claws enable the male and female buckles to have multiple acting positions when the male buckle is connected to the female buckle, improving the stability of the clamping structure of the male and female buckles; at the same time, the plurality of claws can be pressed and move closer to the center of the male buckle to release the clamping between the claws and the female buckle, so that the male buckle can be disengaged from the female buckle, thereby enabling the disassembly of the plastic trim and the sheet metal.

[0016] In one embodiment, the claw includes an inverted hook platform, and the inverted hook platform can pass through the female buckle and abut against the female buckle.

[0017] In one embodiment, a clamping platform is further provided on the male buckle, and the clamping platform can abut against the female buckle to limit the insertion depth of the male buckle into the female buckle.

[0018] It can be understood that setting the clamping platform can make the male buckle abut against the female buckle when the male buckle is inserted into the female buckle, so that the male buckle does not insert into the female buckle excessively, ensuring that the male and female buckles can achieve the clamping function.

[0019] In one embodiment, the female buckle and the elastic piece are integrally provided; and / or, the male buckle and the clamping claw are integrally provided.

[0020] It can be understood that the integrally structured setting can simplify the production process of the male and female buckles, thereby reducing the production cost of the male and female buckles. Moreover, the integrally structured setting of the female buckle and the elastic piece and the integrally structured setting of the male buckle and the clamping claw make the connection structure of the female buckle and the male buckle simple, reduce the possibility of the connection breakage of the male buckle and the female buckle themselves, and further increase the stability of the clamping structure of the male and female buckles.

[0021] The present application also provides the following technical solution:

[0022] A vehicle includes the male and female buckles in any of the above embodiments.

[0023] It can be understood that the above male and female buckles are applied to the technical field of the connection and assembly of vehicle plastic trim parts and sheet metal.

[0024] Compared with the prior art, the male and female buckles are provided with a female buckle and a male buckle. An elastic piece is provided on the female buckle. After the female buckle drives the elastic piece to pass through the sheet metal, the elastic piece on the female buckle can abut against the sheet metal. Then, the male buckle is inserted into the female buckle, and the male buckle and the female buckle are in clamping cooperation to complete the connection and fixation of the plastic trim part and the sheet metal. In this way, only the cooperation of the female buckle and the male buckle is required for fixed connection. Moreover, when disassembling, only the male buckle needs to be disengaged to complete the disassembly. The installation is simple and time-consuming, and it is convenient to disassemble. At the same time, when the male and female buckles are fixedly connected to the vehicle trim and the sheet metal, they will not deform, so they are not easily broken or aged, and the reuse rate is relatively high.

The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0035] Please refer to Figures 1 to 3, the present application provides a snap fastener 100, which is applied to the connection of vehicle plastic trim parts and sheet metal in automobiles and the like, and is mainly used for clamping plastic trim parts and sheet metal structures, simplifying the installation and disassembly processes, and reducing the breakage caused by the long-term deformation and aging of the female fastener 10 structure, thereby increasing the clamping stability and reusability of the snap fastener 100; and it can solve the problem of the snap fastener 100 structure being overly deformed and broken during vehicle vibration, resulting in the failure of the snap connection.

[0036] As Figures 1 to 3 shown, the snap fastener 100 includes a female fastener 10 and a male fastener 20. Among them, the female fastener 10 is used to connect the sheet metal, and an elastic piece 11 is provided on the female fastener 10. The elastic piece 11 can pass through the sheet metal under the drive of the female fastener 10 and abut against the sheet metal; the male fastener 20 is used to connect the plastic trim part, and the male fastener 20 can be inserted into the female fastener 10 and be snap-fitted with the female fastener 10.

[0037] It should be explained that for the connection method of screws or bolts, it is necessary to act on the screws or bolts through external mechanical parts to complete the connection and fixation of plastic trim parts and sheet metal. The installation process is relatively complex, and the disassembly takes a long time, thus increasing the required cost. Currently, the common snap fastener 100 is used instead of screws or bolts. However, when the current snap fastener 100 is used to connect and fix plastic trim parts and sheet metal, the structure needs to be deformed. However, a structure that is deformed for a long time is prone to aging and breakage, resulting in the failure of the connection and making it impossible to be reused. Therefore, in the present application, by providing the female fastener 10 and the male fastener 20, and providing the elastic piece 11 on the female fastener 10, after the female fastener 10 drives the elastic piece 11 to pass through the sheet metal, the elastic piece 11 on the female fastener 10 can abut against the sheet metal, and then the male fastener 20 is inserted into the female fastener 10, and the male fastener 20 is snap-fitted with the female fastener 10 to complete the connection and fixation of the plastic trim part and the sheet metal. In this way, only the cooperation of the female fastener 10 and the male fastener 20 is required to fix the connection. When disassembling, only the male fastener 20 needs to be removed to complete the disassembly. The installation is simple and time-consuming, and it is convenient to disassemble; at the same time, when the snap fastener 100 is used to fixedly connect the vehicle trim and the sheet metal, it will not deform, so it is not easy to break and age, and the reusability is relatively high.

[0038] In an embodiment, please refer to Figure 1 and Figure 2 , a rib 111 is provided on the elastic piece 11. The rib 111 can snap-fit with the male fastener 20 on the female fastener 10 to limit the deformation of the elastic piece 11 towards the axis of the female fastener 10. In this way, when the male fastener 20 is inserted into the female fastener 10 and passes through the rib 111, the rib 111 can abut against the male fastener 20 and limit the elastic piece 11 from leaning towards the axis direction of the female fastener 10, and make the structure of the female fastener 10 not easy to break due to deformation, increasing the stability of the structure of the female fastener 10.

[0039] Preferably, the rib 111 is disposed at any position on the elastic piece 11 toward the center side of the female buckle 10. In this embodiment, the rib 111 is disposed at the 1 / 2 position of the elastic piece 11.

[0040] Specifically, the female buckle 10 and the elastic piece 11 are provided as an integral body. It can be understood that the setting of the integral structure of the female buckle 10 and the elastic piece 11 simplifies the production process of the female buckle 10, thereby reducing the production cost of its structure. Moreover, the setting of the integral structure makes the connection structure on the female buckle 10 simpler, reduces the possibility of the fracture of the structure of the female buckle 10 itself, and thus increases the stability of the snap structure of the male and female buckles 100.

[0041] In one embodiment, the number of the elastic pieces 11 is configured to be multiple, and the multiple elastic pieces 11 are arranged at intervals along the circumferential direction of the female buckle 10. It can be understood that setting multiple elastic pieces 11 can increase the abutting force of the elastic piece 11 structure on the sheet metal, thereby increasing the stability of the fixing structure of the elastic piece 11 to the sheet metal. At the same time, using multiple elastic pieces 11 arranged at intervals in the circumferential direction to abut against the sheet metal part makes the female buckle 10 and the sheet metal part have multiple acting positions when the female buckle 10 is connected to the sheet metal part, which can improve the stability of the female buckle 10 when connected to the sheet metal part.

[0042] Preferably, the number of the elastic pieces 11 can be configured to be two, three, four, etc. In this embodiment, the number of the elastic pieces 11 is set to two.

[0043] Furthermore, a guiding inclined surface 112 is formed on the elastic piece 11, and the guiding inclined surface 112 is used to guide the elastic piece 11 through the sheet metal. It can be understood that during the movement of the female buckle 10 inserted into the sheet metal, the sheet metal can always fit against the guiding inclined surface 112, thereby guiding the elastic piece 11 through the sheet metal and enabling the female buckle 10 to pass through the sheet metal to complete the snap connection of the female buckle 10 to the sheet metal.

[0044] In one embodiment, please continue to refer to Figure 1 and Figure 2 , and an abutting surface 113 is further formed on the elastic piece 11, and the abutting surface 113 can abut against the sheet metal to limit the female buckle 10 to the sheet metal.

[0045] As Figures 1 to 3As shown in the figure, a plurality of claws 21 are provided on the male buckle 20, and the plurality of claws 21 can be respectively clamped with the female buckle 10; wherein, the plurality of claws 21 are arranged at intervals along the circumferential direction of the male buckle 20. In this way, through the arrangement of the claws 21, during the clamping process of the male and female buckles 100, the male buckle 20 can be clamped and fixed on the female buckle 10 to prevent the male buckle 20 from falling off the female buckle 10. Moreover, when the male buckle 20 is connected to the female buckle 10, the plurality of claws 21 enable the two to have multiple acting positions, improving the stability of the clamping structure of the male buckle 20 and the female buckle 10; at the same time, the plurality of claws 21 can be pressed and move closer to the center of the male buckle 20 to release the clamping between the claws 21 and the female buckle 10, so that the male buckle 20 can be disengaged from the female buckle 10, thereby enabling the disassembly of the plastic trim and the sheet metal to be completed.

[0046] Further, the claw 21 includes a barb platform 211, and the barb platform 211 can pass through the female buckle 10 and abut against the female buckle 10.

[0047] Please continue to refer to Figures 1 to 3 , a clamping platform 22 is further provided on the male buckle 20. The clamping platform 22 can abut against the female buckle 10 and is used to limit the insertion depth of the male buckle 20 into the female buckle 10. By providing the clamping platform 22, when the male buckle 20 is inserted into the female buckle 10, it can abut against the female buckle 10, so that the male buckle 20 does not insert excessively into the female buckle 10, ensuring that the male and female buckles 100 can achieve the clamping function.

[0048] Further, the male buckle 20 and the claw 21 are provided as an integral body. It can be understood that the setting of the integral structure of the male buckle 20 and the elastic claw 21 simplifies the production process of the male buckle 20, thereby reducing the production cost of its structure. Moreover, the setting of the integral structure makes the connection structure on the male buckle 20 simpler, reducing the possibility of the fracture of the structure of the male buckle 20 itself, thereby increasing the stability of the clamping structure of the male and female buckles 100.

[0049] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0050] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
