Description

Technical Field

[0001] This application relates to the field of vehicle connection structure technology, and in particular to a snap-fit ​​structure and a vehicle. Background Technology

[0002] With the development of automotive technology, the requirements for automotive interior and exterior trim are becoming increasingly stringent. Existing automotive interior and exterior trim parts, such as dashboard trim and brackets, are typically fixed using self-tapping screws or single-sided clips.

[0003] Using self-tapping screws for fixing increases component costs and takes longer to assemble than conventional clips, impacting production cycle time. Single-sided clips, on the other hand, only guarantee a single-sided connection, easily leading to insecure fastening. Therefore, a locking structure that improves the stability of the connection is needed. Summary of the Invention

[0004] This application provides a snap-fit ​​structure and a vehicle to solve the technical problem of insecure fastening of existing single-sided snap-fit ​​buckles.

[0005] This application provides a snap-fit ​​structure, comprising a first connector and a second connector that cooperate with each other. The first connector includes a first main body, a through hole, and a first snap-fit ​​portion. The through hole extends through the first main body; two first snap-fit ​​portions are provided, located on opposite sides of the outer periphery of the through hole. The second connector includes a second main body, a support portion, and a second snap-fit ​​portion. The projection of the second main body along the axis of the through hole at least partially extends beyond the through hole to restrict the second main body from passing through the through hole; the support portion is fixed to the second main body and is configured to extend through the through hole in a first direction between the two first snap-fit ​​portions; the second snap-fit ​​portions are located on opposite sides of the support portion, and the first snap-fit ​​portions cooperate with the second snap-fit ​​portions to restrict the second main body from moving in the opposite direction relative to the first main body.

[0006] When the first connector is connected to the second connector, the support part passes through the through hole from one side to the other side, and the second main body part is restricted from passing through the through hole. The second snap-fit ​​part cooperates with the first snap-fit ​​part to limit the second main body part and the first main body part, thereby making the first connector and the second connector fixed together and fixing the relevant components.

[0007] The first connector includes two first snap-fit ​​parts, which are respectively located on both sides of the through hole. The two first snap-fit ​​parts cooperate with the two second snap-fit ​​parts to achieve snap-fit ​​limiting on both sides of the second connector. Compared with single-sided snap-fit, double-sided snap-fit ​​is more secure and reliable, reduces the occurrence of shaking and abnormal noise, and improves stability.

[0008] The snap-fit ​​structure of this application can also be integrated onto related components. For example, the first connector and the second connector can be integrated onto the automotive interior panel and automotive interior parts, respectively, reducing the use of fasteners such as self-tapping screws and improving assembly speed and production efficiency.

[0009] In an exemplary embodiment of this application, the first latching portion includes a first latching plate and a second latching plate. The first latching plate is fixed to the first main body portion; the second latching plate is disposed at the end of the first latching plate away from the first main body portion; wherein, the second latching plate is inclined from the direction close to the first latching plate to the direction away from the first latching plate and towards the center of the through hole, and the projection of the second latching plate along the axis of the through hole at least partially overlaps with the through hole; the first latching plate and / or the second latching plate have elastic deformation capability so that the first latching portion and the second latching portion cooperate.

[0010] The first latching portion of this application includes a first latching plate and a second latching plate, with the second latching plate being inclined. Compared to having only one latching plate, when the support portion passes through the first latching portion, the radial component of the force exerted by the support portion on the first latching portion is larger, which makes it easier for the first latching portion to undergo elastic deformation and facilitates the support portion passing through the first latching portion so that the first latching portion and the second latching portion can cooperate.

[0011] When the first latching part and the second latching part are engaged, if the second connector is subjected to a force that causes the second connector to detach from the first connector, the force between the second latching plate and the second latching part causes the first latching part to deform toward the center of the through hole, reducing the risk of the second latching part detaching from the first latching part and improving the stability of the connection between the second connector and the first connector.

[0012] The first card plate can have elastic deformation capability, and the second card plate can cause the first card plate to undergo elastic deformation when subjected to force; or the second card plate can have elastic deformation capability, and elastic deformation can occur between the second card plate and the first card plate when subjected to force; or both the first card plate and the second card plate can have elastic deformation capability, so that the first card plate and the second card plate can undergo elastic deformation.

[0013] The first snap-fit ​​part can be a plastic part or other component with elastic deformation capability. The first snap-fit ​​plate and the second snap-fit ​​plate are integrally formed. The elastic deformation capability of the first snap-fit ​​part causes the first snap-fit ​​part to elastically deform when the support part passes through the first snap-fit ​​part, and the first snap-fit ​​part resets when the second snap-fit ​​part moves to the position to cooperate with the first snap-fit ​​part, so that the first snap-fit ​​part and the second snap-fit ​​part cooperate.

[0014] In an exemplary embodiment of this application, the first card plate is inclined from the direction near the first main body to the direction away from the first main body towards the center of the through hole; the angle between the second card plate and the side of the first card plate near the center of the through hole is an obtuse angle.

[0015] When the second connector detaches from the first connector, the first locking part is subjected to the force applied by the second locking part. The first locking plate tilts from the direction close to the first main body to the direction away from the first main body towards the center of the through hole, which can improve the load-bearing capacity of the first locking plate, reduce the risk of breakage at the connection between the first locking plate and the first main body, and improve the connection strength between the second connector and the first connector.

[0016] The angle between the second card and the first card is an obtuse angle, which reduces the risk of breakage at the connection between the second card and the first card, increases the connection strength between the second motherboard and the first motherboard, and improves durability and stability.

[0017] In an exemplary embodiment of this application, the second snap-fit ​​portion includes a limiting groove, and the first snap-fit ​​portion is inserted into the limiting groove to restrict the relative movement between the second main body portion and the first main body portion.

[0018] Inserting the first snap-fit ​​part into the limiting groove can reduce the risk of the first snap-fit ​​part and the second snap-fit ​​part disengaging, thereby reducing the risk of the second connector disengaging from the first connector and improving connection stability and tightness.

[0019] In an exemplary embodiment of this application, the limiting groove includes a first limiting surface and a second limiting surface. The first limiting surface is configured to abut against a first engaging portion, and the angle between the first limiting surface and a first direction is not less than 30°; the second limiting surface is located on the side of the second limiting surface closer to the first main body portion; wherein, the first limiting surface intersects with the second limiting surface or the extension surface of the first limiting surface intersects with the extension surface of the second limiting surface.

[0020] The first limiting surface abuts against the first engaging portion. When the second engaging portion tends to disengage from the first engaging portion, the contact point between the first engaging portion and the first limiting surface tends to move along the first limiting surface. The first limiting surface applies a force to the first engaging portion in the opposite direction along the first direction. This force can be decomposed into two components: one along the first limiting surface and one perpendicular to the first limiting surface. The component perpendicular to the first limiting surface causes the first limiting surface to press against the first engaging portion, thereby generating friction between them. By ensuring that the angle between the first limiting surface and the first direction is not less than 30°, the friction between the first limiting surface and the first engaging portion can be increased, and the force applied by the first limiting surface to the first engaging portion along the direction of the first limiting surface can be reduced. This reduces the sliding of the first engaging portion along the first limiting surface, improves the connection stability between the first engaging portion and the first limiting surface, and enhances the connection stability between the first connecting member and the second connecting member.

[0021] In an exemplary embodiment of this application, the first connector includes a pressing member disposed on the side of the first main body portion near the second main body portion, and the pressing member presses against the second main body portion when the first snap-fit ​​portion and the second snap-fit ​​portion are engaged.

[0022] The pressing member presses against the second main body, thereby applying a force to the second main body in a direction away from the first main body, reducing the movement of the second main body in the direction of the first main body, reducing the shaking between the second connector and the first connector, and improving the connection stability between the second connector and the first connector.

[0023] In an exemplary embodiment of this application, the pressing member includes two members, which are symmetrically arranged on both sides of the through hole; along the direction from near the first main body to away from the first main body, the pressing member is inclined towards the center of the through hole or away from the center of the through hole.

[0024] The symmetrical arrangement of the two pressure members improves the balance of forces on the second main body, reduces the risk of rotation of the second main body, and improves the stability of the connection between the second main body and the first main body.

[0025] The pressing component can be made of plastic, rubber, or other elastically deformable parts. When the pressing component is tilted, the force applied by the second main body to the pressing component causes stress concentration at the connection between the pressing component and the first main body, making the deformation position of the pressing component stable and controllable. This ensures that the force exerted by the pressing component on the second main body is stable and controllable, improving the consistency and stability of the connection.

[0026] In an exemplary embodiment of this application, the support portion includes a guide portion disposed at one end of the support portion away from the second main body portion; the radial dimension of the guide portion gradually increases along the direction from away from the second main body portion to close to the second main body portion, and the radial direction of the guide portion is the direction of the line connecting the two second snap-fit ​​portions.

[0027] When the guide moves along the first direction, it presses against the first locking part, and the two first locking parts elastically deform in opposite directions. By decreasing the radial dimension of the guide, the elastic deformation of the first locking parts gradually increases, avoiding a sudden increase in the deformation of the first locking parts, reducing the risk of breakage of the first locking parts, and improving durability and stability.

[0028] In an exemplary embodiment of this application, the support portion includes a first support plate, a second support plate, and a connecting support plate. The first support plate is connected to the second main body portion; the second support plate is connected to the second main body portion, and a gap is formed between the second support plate and the first support plate; the connecting support plate is connected to the second main body portion, and the connecting support plate is disposed within the gap or at the end of the gap, connecting the first support plate and the second support plate; the support portion is interference-fitted with the through hole, or the gap between the support portion and the edge of the through hole is not greater than a preset threshold.

[0029] The gap between the first support plate and the second support plate reduces the weight of the support part, and at the same time facilitates the integral injection molding of the first support plate, the second support plate and the first main body, reducing the risk of cracking and damage to the support part after injection molding.

[0030] The connecting support plate connects the first support plate and the second support plate, forming a whole with the first and second support plates, ensuring the overall strength of the support and reducing the risk of deformation of the first and second support plates.

[0031] The support part can be interference-fitted with the through hole, and the gap between the support part and the edge of the through hole can be no greater than a preset threshold, thereby limiting the relative displacement between the support part and the through hole, reducing the shaking between the first connector and the second connector, and improving the connection stability between the first connector and the second connector.

[0032] A second aspect of this application provides a vehicle, which includes a first connector, a second connector, and a snap-fit ​​structure of any one of the above; wherein the first connector is fixed to the first connector, the second connector is fixed to the second connector, and the first connector and the second connector are connected through the first connector and the second connector.

[0033] The first and second components to be connected are connected by a first connector and a second connector. The connection method is simple and stable, and the connection between the first and second components to be connected is stable and reliable. At the same time, it can also improve assembly speed, increase production efficiency, reduce the use of fasteners, and reduce costs.

[0034] In combination with existing technologies, the beneficial effects of this application are as follows: Existing snap-fit ​​devices are single-sided snap-fit ​​devices, which may result in loose connections. The snap-fit ​​structure of this application includes two first snap-fit ​​parts, which are respectively located on both sides of the through hole. By cooperating with two second snap-fit ​​parts, the snap-fit ​​and limiting of the two sides of the second connecting part are achieved. Compared with single-sided snap-fit ​​devices, double-sided snap-fit ​​is more secure and reliable, reduces shaking and abnormal noise, and improves stability.

[0035] The snap-fit ​​structure of this application can also be integrated onto related components. For example, the first connector and the second connector can be integrated onto the automotive interior panel and automotive interior parts, respectively, reducing the use of fasteners such as self-tapping screws and improving assembly speed and production efficiency.

[0039] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application.

[0041] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present application. However, it will be apparent to those skilled in the art that embodiments of the present application may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present application.

[0042] It should be noted that the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of this application.

[0043] There are generally two existing methods for fixing automotive interior and exterior trim parts. One method uses self-tapping screws, metal clips, and other connectors. This method requires separate connectors, which are expensive and complex to assemble, affecting assembly efficiency. The other method uses single-sided plastic clips on the interior and exterior trim parts. Single-sided clips can only guarantee one-sided engagement, which can easily lead to problems such as loose fastening, shaking, and abnormal noise, affecting the user experience.

[0044] In view of this, this application provides a snap-fit ​​structure for vehicles, which realizes snap-fit ​​limiting on both sides of the second connecting part. Compared with single-sided snap-fit, double-sided snap-fit ​​is firm and reliable, reduces the occurrence of shaking and abnormal noise, and improves stability.

[0045] Please see Figures 1 to 9 The first aspect of this application provides a snap-fit ​​structure, which includes a first connector 100 and a second connector 200 that cooperate with each other.

[0046] The first connector 100 connects to the first component to be connected, and the second connector 200 connects to the second component to be connected. The connection between the first connector 100 and the second connector 200 achieves the connection and fixation between the first component to be connected and the second component to be connected.

[0047] The first connector 100 can be a separate structure, which is fixed to the first component to be connected during use. Alternatively, the first connector 100 can be integrated into the first component to be connected for ease of use, simplified assembly procedures, and improved assembly efficiency.

[0048] Similarly, the second connector 200 can be a separate structure, which is fixed to the second component to be connected during use. Alternatively, the second connector 200 can be integrated into the second component to be connected for ease of use, simplified assembly procedures, and improved assembly efficiency.

[0049] Please see Figures 4 to 6The first connector 100 includes a first main body 110, a through hole 120, and a first snap-fit ​​part 130.

[0050] The first main body 110 provides a connecting carrier for other components of the first connector 100, making the first connector 100 an integral unit. For example, the first connector 100 is a plate-like structure, with a through hole 120 penetrating the plate-like structure and a first snap-fit ​​portion 130 fixed to the plate-like structure. In some embodiments, the first connector 100 is integrated into the first component to be connected, in which case the first main body 110 can serve as part of the structure of the first component to be connected, reducing redundant structures and facilitating production and use.

[0051] The through hole 120 passes through the first main body 110, so that part of the structure of the second connector 200 passes through the through hole 120 from the side away from the first snap-fit ​​part 130 to the side close to the first snap-fit ​​part 130, thereby realizing the connection between the first connector 100 and the second connector 200.

[0052] The first snap-fit ​​portion 130 is fixed to the first main body portion 110. Two first snap-fit ​​portions 130 are provided, located on opposite sides of the outer periphery of the through hole 120. When a portion of the second connector 200 passes through the through hole 120, the two first snap-fit ​​portions 130 can clamp both sides of the second connector 200. Compared to single-sided fastening, double-sided fastening is more stable and reduces shaking, abnormal noise, and other issues.

[0053] Please see Figures 7 to 9 The second connector 200 includes a second main body 210, a support 220, and a second snap-fit ​​230.

[0054] The second main body 210 provides a connecting carrier for other components of the second connector 200, making the second connector 200 an integral unit. For example, the second connector 200 is a plate-like structure, and the support 220 is fixed to the plate-like structure. In some embodiments, the second connector 200 is integrated into the second component to be connected, in which case the second main body 210 can serve as part of the structure of the second component to be connected, reducing redundant structures and facilitating production and use.

[0055] The projection of the second main body portion 210 along the axis of the through hole 120 at least partially extends beyond the through hole 120, thereby restricting the second main body portion 210 from passing through the through hole 120. The support portion 220 needs to pass through the through hole 120 so that the second snap-fit ​​portion 230 can cooperate with the first snap-fit ​​portion 130. The area of ​​the first main body portion 110 where the through hole 120 is not provided restricts the second main body portion to the side of the first main body portion 110 away from the first snap-fit ​​portion 130, preventing the second connector 200 from passing entirely through the through hole 120, thus achieving a secure connection.

[0056] The support portion 220 is fixed to the second main body portion 210. The support portion 220 is used to pass through the through hole 120 along the first direction to the space between the two first snap-fit ​​portions 130. The support portion 220 serves both a supporting and connecting function for the second snap-fit ​​portion 230, connecting the second snap-fit ​​portion 230 and the second main body portion 210 into one unit. Simultaneously, it ensures that the second snap-fit ​​portion 230 and the second main body portion 210 are located on opposite sides of the through hole 120, thereby limiting the positioning of the first connector 100 and the second connector 200 along the axial direction of the through hole 120. The first direction refers to the direction in which the second connector 200 moves relative to the first connector 100 to a mating position with the first connector 100, setting the direction in which the first connector 100 remains fixed and the second connector 200 moves relative to the first connector 100, for example... Figure 3 The X direction in the equation.

[0057] The second snap-fit ​​portion 230 is disposed on opposite sides of the support portion 220. The first snap-fit ​​portion 130 cooperates with the second snap-fit ​​portion 230 to restrict the second main body portion 210 from moving in the opposite direction relative to the first main body portion 110 in the first direction, thereby realizing the connection and fastening of the first connector 100 and the second connector 200.

[0058] The first latching part 130 and the second latching part 230 can have various forms of engagement. For example, the first latching part 130 can be a slot and the second latching part 230 can be a block. The first connector 100 and the second connector 200 can be latched and fixed by the engagement of the slot and the block. Alternatively, the first latching part 130 can be a block and the second latching part 230 can be a slot. The first connector 100 and the second connector 200 can be latched and fixed by the engagement of the slot and the block.

[0059] Of course, as some alternatives, the first latching part 130 and the second latching part 230 can also be in other forms of engagement. For example, the first latching part 130 and the second latching part 230 can both be latching blocks. The first connector 100 and the second connector 200 are limited by the pressure of the two latching blocks, so as to prevent the second connector 200 from disengaging from the first connector 100 in the opposite direction of the first direction.

[0060] When the first connector 100 is connected to the second connector 200, the support part 220 passes through the through hole 120 from one side to the other side. The second main body part 210 is restricted from passing through the through hole 120. The second snap-fit ​​part 230 cooperates with the first snap-fit ​​part 130 to limit the second main body part 210 and the first main body part 110, thereby making the first connector 100 and the second connector 200 cooperate and fix them, thus fixing the relevant components.

[0061] The first connector 100 includes two first snap-fit ​​parts 130, which are respectively disposed on both sides of the through hole 120. The two first snap-fit ​​parts 130 cooperate with the two second snap-fit ​​parts 230 to achieve snap-fit ​​limiting on both sides of the second connector. Compared with single-sided snap-fit, double-sided snap-fit ​​is firm and reliable, reduces the occurrence of shaking and abnormal noise, and improves stability.

[0062] The snap-fit ​​structure of this application can also be integrated onto related components. For example, the first connector 100 and the second connector 200 can be integrated onto the automotive interior panel and automotive interior parts, respectively, reducing the use of fasteners such as self-tapping screws, lowering costs, and improving assembly speed and production efficiency.

[0063] Please see Figure 3 and Figure 4 In some embodiments, the first latching portion 130 includes a first latching plate 131 and a second latching plate 132.

[0064] The first card plate 131 is fixed to the first main body 110, and the second card plate 132 is disposed at the end of the first card plate 131 away from the first main body 110. For example, the first card plate 131, the second card plate 132 and the first main body 110 are integrally formed, for example by injection molding.

[0065] The second card plate 132 is inclined from the direction close to the first card plate 131 away from the first card plate 131 toward the center of the through hole 120, and the projection of the second card plate 132 along the axis of the through hole 120 at least partially overlaps with the through hole 120.

[0066] The first latching portion 130 of this application includes a first latching plate 131 and a second latching plate 132, with the second latching plate 132 being inclined. Compared to having only one latching plate, when the support portion 220 passes through the first latching portion 130, the radial component of the force exerted by the support portion 220 on the first latching portion 130 is larger, making it easier for the first latching portion 130 to undergo elastic deformation. This facilitates the support portion 220 passing through the first latching portion 130 so that the first latching portion 130 and the second latching portion 230 can cooperate.

[0067] After the first latching part 130 and the second latching part 230 are engaged, if the second connector 200 is subjected to a force that causes the second connector 200 to tend to detach from the first connector 100, the force between the second latching plate 132 and the second latching part 230 causes the first latching part 130 to deform toward the center of the through hole 120, reducing the risk of the second latching part 230 detaching from the first latching part 130 and improving the stability of the connection between the second connector 200 and the first connector 100.

[0068] The first locking plate 131 and / or the second locking plate 132 have elastic deformation capabilities so that the first locking portion 130 and the second locking portion 230 cooperate.

[0069] The first card plate 131 may have elastic deformation capability, and the second card plate 132 may cause the first card plate 131 to undergo elastic deformation when subjected to force; or the second card plate 132 may have elastic deformation capability, and elastic deformation may occur between the second card plate 132 and the first card plate 131 when subjected to force; or both the first card plate 131 and the second card plate 132 may have elastic deformation capability, so that the first card plate 131 and the second card plate 132 may undergo elastic deformation.

[0070] The first snap-fit ​​portion 130 can be a plastic part or other component with elastic deformation capability. The first snap-fit ​​plate 131 and the second snap-fit ​​plate 132 are integrally formed. The elastic deformation capability of the first snap-fit ​​portion 130 causes the first snap-fit ​​portion 130 to elastically deform when the support portion 220 passes through the first snap-fit ​​portion 130. When the second snap-fit ​​portion 230 moves to the position to cooperate with the first snap-fit ​​portion 130, the first snap-fit ​​portion 130 resets, so that the first snap-fit ​​portion 130 and the second snap-fit ​​portion 230 cooperate.

[0071] Please see Figure 6 In some embodiments, the first card plate 131 is inclined from the direction near the first main body portion 110 to the direction away from the first main body portion 110 toward the center of the through hole 120.

[0072] When the second connector 200 disengages from the first connector 100, the first latching portion 130 is subjected to the force applied by the second latching portion 230. The first latching plate 131 tilts from the direction close to the first main body portion 110 to the direction away from the first main body portion 110 towards the center of the through hole 120, which can improve the load-bearing capacity of the first latching plate 131, reduce the risk of breakage at the connection between the first latching plate 131 and the first main body portion 110, and improve the connection strength between the second connector 200 and the first connector 100.

[0073] When the second connector 200 is engaged with the first connector 100, the support 220 presses the two first snap-fit ​​parts 130 to deform in opposite directions. Since the shape of the support 220 is fixed, the deformation of the first snap-fit ​​parts 130 is controllable, ensuring that the connection between the first snap-fit ​​plate 131 and the first connector remains connected and preventing breakage.

[0074] The angle between the second card plate 132 and the first card plate 131 on the side closest to the center of the through hole 120 is an obtuse angle, which reduces the risk of breakage at the connection between the second card plate 132 and the first card plate 131, improves the connection strength at the connection between the second main board and the first main board, and enhances durability and stability.

[0075] Please see Figure 6The angle between the second card plate 132 and the side of the first card plate 131 closest to the center of the through hole 120 is an obtuse angle. Therefore, the tilt angle of the second card plate 132 is larger than that of the first card plate 131, which facilitates the second card plate 132 to cooperate with the second latching part 230 in the direction closer to the center of the through hole 120, while reducing the risk of interference between the first card plate 131 and the second connector 200.

[0076] Please see Figures 7 to 9 In some embodiments, the second snap-fit ​​portion 230 includes a limiting groove 231, and the first snap-fit ​​portion 130 is inserted into the limiting groove 231 to restrict the relative movement between the second main body portion 210 and the first main body portion 110.

[0077] The limiting groove 231 is provided on both sides of the support part 220. The insertion of the first snap-fit ​​part 130 into the limiting groove 231 can reduce the risk of the first snap-fit ​​part 130 and the second snap-fit ​​part 230 disengaging, thereby reducing the risk of the second connector 200 disengaging from the first connector 100 and improving the connection stability and tightness.

[0078] Please see Figure 1 , Figure 6 and Figure 9 For example, the second card plate 132 is inserted into the limiting groove 231 and cooperates with the limiting groove 231. The limiting groove 231 restricts the second card plate 132 from leaving the limiting groove 231, thereby fixing the first connector 100 and the second connector 200.

[0079] Please see Figure 9 In some embodiments, the limiting groove 231 includes a first limiting surface 2311 and a second limiting surface 2312.

[0080] The first limiting surface 2311 is used to abut against the first engaging portion 130, and the angle α between the first limiting surface 2311 and the first direction is not less than 30°. When the second engaging portion 230 tends to disengage from the first engaging portion 130, the contact point between the first engaging portion 130 and the first limiting surface 2311 tends to move along the first limiting surface 2311. The first limiting surface 2311 applies a force to the first engaging portion 130 in the opposite direction in the first direction. This force can be decomposed into two components: one along the first limiting surface 2311 and the other perpendicular to the first limiting surface 2311. The component perpendicular to the first limiting surface 2311 causes the first limiting surface 2311 to press against the first engaging portion 130, thereby generating friction between the first limiting surface 2311 and the first engaging portion 130. By ensuring that the angle α between the first limiting surface 2311 and the first direction is not less than 30°, the friction between the first limiting surface 2311 and the first engaging part 130 can be increased, and the force exerted by the first limiting surface 2311 on the first engaging part 130 along the direction of the first limiting surface 2311 can be reduced, thereby reducing the sliding of the first engaging part 130 along the first limiting surface 2311, improving the connection stability between the first engaging part 130 and the first limiting surface 2311, and improving the connection stability between the first connecting member 100 and the second connecting member 200.

[0081] For example, the angle α between the first limiting surface 2311 and the first direction can be any angle between 30° and 90°, such as 30°, 45°, 60°, 90°, etc., to increase the friction between the first limiting surface 2311 and the first engaging part 130, reduce the force exerted by the first limiting surface 2311 on the first engaging part 130 along the direction of the first limiting surface 2311, thereby reducing the sliding of the first engaging part 130 along the first limiting surface 2311, improving the connection stability between the first engaging part 130 and the first limiting surface 2311, and improving the connection stability between the first connecting member 100 and the second connecting member 200.

[0082] The second limiting surface 2312 is located on the side of the second limiting surface 2312 closer to the first main body 110. The first limiting surface 2311 intersects with the second limiting surface 2312 or the extension surface of the first limiting surface 2311 intersects with the extension surface of the second limiting surface 2312.

[0083] By setting the first limiting surface 2311 and the second limiting surface 2312 to be non-parallel, it is more conducive to fixing the limiting groove 231 and the first snap-fit ​​part 130, reducing the risk of relative sliding between the first snap-fit ​​part 130 and the limiting groove 231.

[0084] Of course, as some alternatives, the first limiting surface 2311 and the second limiting surface 2312 can also be parallel surfaces, and the second card plate 132 is inserted into the limiting groove 231 and at least partially abuts against the first limiting surface 2311 to limit the second connector 200 from moving in the opposite direction relative to the first connector 100 in the first direction.

[0085] Please see Figure 4and Figure 6 In some embodiments, the second card plate 132 includes a first card contact surface 1321 and a second card contact surface 1322.

[0086] When the second card plate 132 is inserted into the limiting groove 231, the first card contact surface 1321 is in contact with the first limiting surface 2311, and the second card contact surface 1322 is parallel to the second limiting surface 2312 with a gap less than a preset threshold.

[0087] By having the first contact surface 1321 fit against the first limiting surface 2311, the friction between the first contact surface 1321 and the first limiting surface 2311 is ensured, thereby reducing the risk of the second card plate 132 disengaging from the limiting groove 231.

[0088] The gap between the second card contact surface 1322 and the second limiting surface 2312 can be any value less than a preset threshold. The gap between the second card contact surface 1322 and the second limiting surface 2312 can also be zero, that is, the second card section is in contact with the second limiting surface 2312.

[0089] When the second connector 200 tends to detach from the first connector 100 in the opposite direction along the first direction, the first limiting surface 2311 applies a force to the first locking surface 1321, causing the second locking plate 132 to twist or elastically deform, so that the second locking surface 1322 fits with the second limiting surface 2312, thereby ensuring the force between the second locking block and the limiting groove 231 and reducing the risk of the second locking block detaching from the limiting groove 231.

[0090] In some embodiments, the intersection of the first latching surface 1321 and the second latching surface 1322 is arc-shaped. When the support portion 220 passes between the two second latching plates 132, the intersection of the first latching surface 1321 and the second latching surface 1322 comes into contact with the support portion 220. By setting the intersection of the first latching surface 1321 and the second latching surface 1322 to be arc-shaped, the risk of damage to the support portion 220 caused by scratching between the second latching block and the support portion 220 is reduced. At the same time, the arc shape helps to improve the smoothness of movement between the second latching block and the support portion 220.

[0091] Please see Figure 4 and Figure 6 In some embodiments, the second card plate 132 includes an extension 133, one side of which is flush with the first contact surface 1321. The extension 133 increases the contact area between the second card plate 132 and the first limiting surface 2311, thereby improving the connection stability.

[0092] Furthermore, the cross-section of the extension 133 is triangular, which ensures the stability of the extension 133 and avoids the possibility of breakage or deformation between the extension 133 and the first contact surface 1321.

[0093] Please see Figure 3 and Figure 5 In some embodiments, the first connector 100 includes a pressing member 140 disposed on the side of the first main body 110 near the second main body 210, and the pressing member 140 presses against the second main body 210 when the first snap-fit ​​portion 130 and the second snap-fit ​​portion 230 are engaged.

[0094] The pressing member 140 presses against the second main body 210, thereby applying a force to the second main body 210 in a direction away from the first main body 110, reducing the movement of the second main body 210 in the direction of the first main body 110, reducing the shaking between the second connector 200 and the first connector 100, and improving the connection stability between the second connector 200 and the first connector 100.

[0095] For example, the pressing member 140 is a sheet-like structure, and its shape can be square, arc, or other shapes. The pressing member 140 is fixed on the first main body 110.

[0096] In some embodiments, the pressing member 140 includes two members, which are symmetrically arranged on both sides of the through hole 120.

[0097] The two pressure members 140 are symmetrically arranged to improve the force balance of the second main body 210, reduce the risk of rotation of the second main body 210, and improve the stability of the connection between the second main body 210 and the first main body 110.

[0098] In some embodiments, the pressing member 140 is inclined toward the center of the through hole 120 along the direction from near the first body portion 110 to away from the first body portion 110.

[0099] The pressing member 140 can be a plastic, rubber or other elastically deformable component. When the pressing member 140 is tilted, the force applied by the second main body 210 to the pressing member 140 causes stress concentration at the connection between the pressing member 140 and the first main body 110, making the deformation position of the pressing member 140 stable and controllable. This ensures that the force exerted by the pressing member 140 on the second main body 210 is stable and controllable, and improves the consistency and stability of the connection.

[0100] Please see Figure 6 In other embodiments, along the direction from near the first body portion 110 to away from the first body portion 110, the pressing member 140 is inclined in a direction away from the center of the through hole 120.

[0101] When the pressing member 140 is tilted, the force exerted by the second main body 210 on the pressing member 140 causes stress concentration at the connection between the pressing member 140 and the first main body 110, making the deformation position of the pressing member 140 stable and controllable, thereby ensuring that the force exerted by the pressing member 140 on the second main body 210 is stable and controllable, and improving the consistency and stability of the connection.

[0102] Please see Figure 3 and Figure 6 In some embodiments, the support portion 220 includes a guide portion 221, which is disposed at one end of the support portion 220 away from the second main body portion 210. The radial dimension of the guide portion 221 gradually increases along the direction from away from the second main body portion 210 to close to the second main body portion 210, and the radial direction of the guide portion 221 is the direction of the line connecting the two second snap-fit ​​portions 230.

[0103] When the guide portion 221 moves along the first direction, it presses against the first locking portion 130, and the two first locking portions 130 elastically deform in opposite directions. By decreasing or increasing the radial dimension of the guide portion 221, the elastic deformation of the first locking portion 130 gradually increases, avoiding a sudden increase in the deformation of the first locking portion 130, reducing the risk of breakage of the first locking portion 130, and improving durability and stability.

[0104] In some embodiments, the transition between the guide portion 221 and the second latching portion 230 is arc-shaped, so that the contact point of the first latching portion 130 is reset from the guide portion 221 to the second latching portion 230 more smoothly.

[0105] Please see Figures 7 to 9 In some embodiments, the support portion 220 includes a first support plate 222, a second support plate 223, and a connecting support plate 224.

[0106] The first support plate 222 is connected to the second main body 210, and the second support plate 223 is connected to the second main body 210. A gap is formed between the second support plate 223 and the first support plate 222. The gap between the first support plate 222 and the second support plate 223 reduces the weight and thickness of the support part 220, facilitates the injection molding of the support part 220, and reduces the risk of injection molding cracking.

[0107] For example, both the first support plate 222 and the second support plate 223 are plate-shaped structures.

[0108] The connecting support plate 224 is connected to the second main body 210. The connecting support plate 224 is disposed in the gap or at the end of the gap. The connecting support plate 224 connects the first support plate 222 and the second support plate 223.

[0109] The connecting support plate 224 can be disposed within the gap or at the end of the gap. By fixing the connecting support plate 224 to the first support plate 222 and the second support plate 223, the support part 220 is made into a whole, ensuring the overall strength of the support part 220. On the other hand, the connecting support plate 224 supports the first support plate 222 and the second support plate 223, reducing the risk of deformation of the first support plate 222 and the second support plate 223.

[0110] Please see Figure 7 In some embodiments, the connecting support plate 224 is disposed at the end of the gap, and the first support plate 222, the second support plate 223 and the connecting support plate 224 form a hollow cavity 225. The top of the hollow cavity 225 is an inclined surface, and the inclined surface is parallel to the second limiting surface 2312 on the same side.

[0111] The parallelism between the inclined surface and the second limiting surface 2312 on the same side ensures the uniformity of the thickness of the first support plate 222 and the second support plate 223, reduces the risk of stress concentration on the first support plate 222 and the second support plate 223, and ensures stability.

[0112] In some embodiments, the top inclined surface of the hollow cavity 225 is parallel to the first limiting surface 2311 on the opposite side, and the extension surface of the top inclined surface of the hollow cavity 225 is located below the first limiting surface 2311 on the opposite side. In other words, the extension surface of the first limiting surface 2311 passes between the second limiting surface 2312 on the opposite side and the top inclined surface of the hollow cavity 225.

[0113] There is a risk of stress concentration at the intersection of the first limiting surface 2311 and the second limiting surface 2312. By extending the first limiting surface 2311 through the opposite side of the second limiting surface 2312 and the inclined surface at the top of the hollow cavity 225, the strength between the two limiting grooves 231 is ensured, the risk of cracking and breakage at the limiting groove 231 is reduced, and the connection stability and reliability are improved.

[0114] In some embodiments, the hollow cavity 225 penetrates the second main body 210, which can reduce the weight of the second connector 200 and reduce the risk of cracking during production, thereby improving the product quality of the second connector 200.

[0115] In some embodiments, the second connector 200 is integrally injection molded, and the first support plate 222, the second support plate 223 and the connecting support plate 224 are also integrally injection molded.

[0116] In some embodiments, the first connector 100 is integrally injection molded.

[0117] In some embodiments, the support portion 220 and the through hole 120 are interference-fitted. This limits the relative displacement between the support portion 220 and the through hole 120, reducing the wobbling between the first connector 100 and the second connector 200, and improving the connection stability between the first connector 100 and the second connector 200.

[0118] In other embodiments, the gap between the support portion 220 and the edge of the through hole 120 is not greater than a preset threshold. Limiting the relative displacement between the support portion 220 and the through hole 120 reduces the swaying between the first connector 100 and the second connector 200, thereby improving the connection stability between the first connector 100 and the second connector 200.

[0119] A second aspect of this application provides a vehicle, which includes a first connector, a second connector, and a snap-fit ​​structure of any one of the above; wherein the first connector 100 is fixed to the first connector, the second connector 200 is fixed to the second connector, and the first connector and the second connector are connected through the first connector 100 and the second connector 200.

[0120] The first component to be connected and the second component to be connected are connected by the first connector 100 and the second connector 200. The connection method is simple and stable, and the connection between the first component to be connected and the second component to be connected is stable and reliable. At the same time, it can also improve the assembly speed, increase production efficiency, reduce the use of fasteners, and reduce costs.

[0121] The first component to be connected can be a car interior panel, center console armrest, seat, or other structure; the second component to be connected can be an interior trim piece, snap-on panel, or other structure. A snap-fit ​​structure enables quick connection between the second and first components, facilitating assembly and production.

[0122] Of course, a vehicle also includes systems or structures such as a running system, frame, body, control system, and power system. Please refer to existing vehicles for details, which will not be elaborated upon in this application.

[0123] The snap-fit ​​structure and vehicle provided in this application include a first connecting member 100 comprising two first snap-fit ​​portions 130, which are respectively disposed on both sides of the through hole 120. The two first snap-fit ​​portions 130 cooperate with two second snap-fit ​​portions 230 to achieve snap-fit ​​limiting on both sides of the second connecting portion. Compared to single-sided snap-fit, the double-sided snap-fit ​​is more secure and reliable, reducing shaking and abnormal noise, and improving stability. It also reduces the use of fasteners such as self-tapping screws, lowering costs and increasing assembly speed and production efficiency. Therefore, this application effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance.

[0124] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
