Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a snap-fit ​​assembly and a vehicle. Background Technology

[0002] With social development and technological advancements, people's living standards are constantly improving, and their demands for vehicle safety, comfort, and reliability are also increasing. Among these, the vehicle's clip-on assembly is an essential component, used to secure plastic products to the corresponding sheet metal.

[0003] Currently, snap-fit ​​assemblies typically include a snap-fit ​​base and a snap-fit ​​structure. The snap-fit ​​base includes a base plate and a snap-fit ​​structure disposed on the base plate. For ease of installation, it is usually configured such that the snap-fit ​​structure snaps onto the snap-fit ​​structure, with a certain distance between the snap-fit ​​structure and the base plate. The base plate is provided with support ribs, which contact the portion of the snap-fit ​​structure located between the snap-fit ​​structure and the base plate to support the snap-fit ​​structure and prevent it from shifting or shaking towards the base plate, thereby improving the stability of the assembly of the snap-fit ​​structure and the snap-fit ​​base.

[0004] However, to ensure that the support rib can stably limit the snap-fit ​​structure, the distance between the support rib of the snap-fit ​​base and the snap-fit ​​structure must be equal to the size of the corresponding part of the snap-fit ​​structure. This requires high manufacturing precision. Due to the influence of process errors and defects, the distance may be too small or too large. If it is too large, the snap-fit ​​structure cannot be stably limited. If it is too small, the support rib and the snap-fit ​​structure will interfere with each other, causing the snap-fit ​​structure to fail to snap onto the snap-fit ​​structure, thus affecting the overall assembly efficiency of the vehicle. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a buckle assembly and a vehicle. By setting a limiting structure on the buckle base and setting an adjustable first clamping part on the buckle base, the distance between the first clamping part and the second snap-fit ​​part can be adjusted, ensuring stable limiting of the second end of the body. This solves the technical problem of unstable assembly or difficult assembly of the buckle structure and buckle base due to process defects.

[0006] In a first aspect, this application provides a snap-fit ​​assembly, comprising: a snap-fit ​​structure including a body extending along a first direction, a first end of the body for connecting to a first component of a vehicle, and a first snap-fit ​​portion disposed between a second end of the body and the first end; a snap-fit ​​base including a base plate and a second snap-fit ​​portion disposed on the base plate and a limiting structure; the base plate for connecting to a second component of the vehicle; the first snap-fit ​​portion and the second snap-fit ​​portion snap-fit ​​along a second direction, the first direction and the second direction having an included angle; the limiting structure having a first clamping portion, the limiting structure driving the first clamping portion to abut against the second end of the body along the first direction under the force of external force or the force stored by deformation.

[0007] The snap-fit ​​assembly provided in this application, by setting a limiting structure on the snap-fit ​​base and making the position of the first clamping part adjustable, facilitates the snap-fit ​​between the first and second snap-fit ​​parts while stably limiting the second end of the body with the first clamping part, preventing the snap-fit ​​structure from shaking or moving towards the substrate; in addition, by adjusting the position of the first clamping part so that it abuts against the body, a static friction force perpendicular to the first direction is generated, preventing the first snap-fit ​​structure from detaching from the second snap-fit ​​structure in the reverse direction of the second direction, thereby improving the assembly strength between the snap-fit ​​structure and the snap-fit ​​base and effectively preventing the snap-fit ​​structure from detaching from the snap-fit ​​base.

[0008] In some implementations, the limiting structure includes an elastically deformable connecting part, the connecting end of which is connected to the substrate, and a first clamping part is provided at the free end. The connecting part deforms by releasing stored force, causing the first clamping part to abut against the second end of the body.

[0009] In some implementations, the extension direction of the connecting part forms an angle with the first direction, and the bending deformation causes the first clamping part to abut against the second end of the body.

[0010] In some implementations, the connecting portion includes a first segment extending from the substrate along a first direction, and a second segment connected to the extended end of the first segment, the second segment being bent and extended in a second direction.

[0011] In some implementations, a clearance opening is provided on the substrate, and the clearance opening is directly opposite the clamping part in a first direction.

[0012] In some implementations, the second snap-fit ​​portion includes a snap-fit ​​wall and a support wall connected to the snap-fit ​​wall. The snap-fit ​​wall is disposed at a certain distance from the substrate. The snap-fit ​​wall is provided with a snap-fit ​​groove for snapping with the second snap-fit ​​portion. The support wall is connected to the substrate. The snap-fit ​​structure includes a mounting portion disposed on the second end of the body. The mounting portion contacts the corresponding side surface of the snap-fit ​​wall. The mounting portion is clamped between the first clamping portion and the snap-fit ​​wall.

[0013] In some implementations, the first clamping part is provided with at least one protruding or recessed limiting part, and the second end of the body is provided with a corresponding assembly part that cooperates with the limiting part.

[0014] In some implementations, the assembly part and the limiting part are provided in a one-to-one correspondence, and the peripheral sidewall of the limiting part is in close contact with the peripheral sidewall of the assembly part.

[0015] In some implementations, the snap-fit ​​structure includes a second clamping part disposed on the body, located between the first snap-fit ​​part and the first end, and the second clamping part abuts against the second snap-fit ​​part.

[0016] Secondly, this application provides a vehicle, including: a first component; a second component; and the buckle assembly described in the first aspect, wherein at least one of the buckle bases is connected to the second component, and the second component is connected to the corresponding first component through a buckle structure on the buckle base.

[0017] In the vehicle of this application, the same beneficial effects can be achieved by including the snap-fit ​​assembly of the first aspect. That is, by providing a limiting structure on the snap-fit ​​base and making the position of the first clamping part adjustable, the first clamping part can be stably limited to the second end of the body while facilitating the snap-fit ​​between the first and second snap-fit ​​parts, preventing the snap-fit ​​structure from shaking or moving towards the substrate; in addition, by adjusting the position of the first clamping part so that it abuts against the body, a static friction force perpendicular to the first direction is generated, preventing the first snap-fit ​​structure from disengaging from the second snap-fit ​​structure in the reverse direction of the second direction, thereby improving the assembly strength between the snap-fit ​​structure and the snap-fit ​​base, thereby improving the connection strength and stability between the second component and the first component, and effectively preventing the separation of the first component and the second component.

[0031] The following is a detailed description of this application.

[0032] The applicant of this application discovered that snap-fit ​​assemblies typically include a snap-fit ​​base and a snap-fit ​​structure. The snap-fit ​​base includes a base plate and a snap-fit ​​structure disposed on the base plate. For ease of installation, it is typically configured such that the snap-fit ​​structure engages with the snap-fit ​​structure, with a distance between the snap-fit ​​structure and the base plate. Support ribs are provided on the base plate, and these support ribs contact the portion of the snap-fit ​​structure located between the snap-fit ​​structure and the base to support the snap-fit ​​structure and prevent it from shifting or wobbling towards the base plate, thereby improving the stability of the assembly of the snap-fit ​​structure and the snap-fit ​​base. To ensure that the snap-fit ​​base can stably limit the snap-fit ​​structure, the distance between the support ribs of the snap-fit ​​base and the snap-fit ​​structure must be equal to the dimension of the corresponding part of the snap-fit ​​structure, requiring high manufacturing precision. However, due to... The snap-fit ​​base and snap-fit ​​structure are usually made of plastic. Due to technical defects such as shrinkage, the actual gap between the support rib and the snap-fit ​​structure may be larger than the design size. It is also possible that due to wear of the mold used to produce the snap-fit ​​base, there are gaps between the molds, resulting in extra protrusions of the support rib and / or snap-fit ​​structure at the parting line. When the protrusion is located on the opposite surface of the support rib and / or snap-fit ​​structure, the actual gap between the support rib and snap-fit ​​structure will be smaller than the design size. If it is too large, it will not be able to stably limit the snap-fit ​​structure; if it is too small, the corresponding part of the snap-fit ​​structure will not be able to be installed between the support rib and the snap-fit ​​structure, affecting the assembly efficiency of the vehicle.

[0033] To address the issues of unstable assembly or assembly difficulties in the snap-fit ​​structure and snap-fit ​​base of the aforementioned snap-fit ​​assembly due to manufacturing defects, this application provides a snap-fit ​​assembly and a vehicle.

[0034] like Figures 1 to 8 As shown, this application provides a snap-fit ​​assembly, including: a snap-fit ​​structure 2, including a body 21, the body 21 extending along a first direction, a first end of the body 21 for connecting a first component of a vehicle, and a first snap-fit ​​portion 211 disposed between the second end 213 of the body 21 and the first end; a snap-fit ​​base 1, including a base plate 12 and a second snap-fit ​​portion 11 disposed on the base plate 12 and a limiting structure 13; the base plate 12 is used to connect with a second component of the vehicle; the first snap-fit ​​portion 211 and the second snap-fit ​​portion 11 snap-fit ​​along a second direction, the first direction and the second direction having an included angle; the limiting structure 13 has a first clamping portion 131, the limiting structure 13, under the force of external force or the force generated by deformation, drives the first clamping portion 131 to abut against the second end 213 of the body 21 along the first direction.

[0035] The buckle structure 2 is engaged with the second buckle base 11 via the first buckle engagement part 211. Its first end and second end 213 are located on both sides of the second buckle engagement part 11, respectively. The first end is connected to the first component, and the opposite second end 213 is limited by the limiting structure 13 to prevent the buckle structure 2 from shaking in the first direction. The specific shape of the buckle structure 2 can be set according to actual production needs.

[0036] The snap-fit ​​base 1 and the base plate 12 can be connected to the second component of the vehicle by one or more combinations of common connection methods such as bonding, welding, screw connection and riveting connection. The snap-fit ​​base 1 is snapped to the snap-fit ​​structure 2 through the second snap-fit ​​part 11, thereby realizing the connection and assembly of the first component and the second component. The plate surface of the base plate 12 can be set to match the shape of the corresponding second component. The specific shape of the snap-fit ​​base 1 can be set according to actual production needs.

[0037] The first direction is the extension direction of the main body 21; specifically, the end face of the second end 213 of the main body 21 faces the first direction; the second direction is the snapping direction of the first snapping part 211, that is, during the installation of the snapping structure 2, the first snapping part 211 moves along the second direction and snaps onto the second snapping part 11.

[0038] With the above configuration, by setting a limiting structure 13 on the snap-fit ​​base 1, and by making the position of the first clamping part 131 adjustable, the first clamping part 211 can be easily snapped into place with the second clamping part 11, while the first clamping part 131 can be stably limited to the second end 213 of the body 21, preventing the snap-fit ​​structure 2 from shaking or moving towards the substrate 12. In addition, by adjusting the position of the first clamping part 131 so that the first clamping part 131 abuts against the body 21, a static friction force perpendicular to the first direction is generated, preventing the first snap-fit ​​structure 2 from disengaging from the second snap-fit ​​structure 2 in the reverse direction of the second direction. This improves the assembly strength between the snap-fit ​​structure 2 and the snap-fit ​​base 1, and effectively prevents the snap-fit ​​structure 2 from disengaging from the snap-fit ​​base 1.

[0039] In the embodiments of this application, the angle between the first direction and the second direction is greater than or equal to 45 degrees; preferably, the angle between the first direction and the second direction is equal to 90 degrees, that is, the first direction and the second direction are orthogonal.

[0040] like Figure 7 and Figure 8 As shown, in an alternative embodiment of this application, the position of the limiting structure 13 is adjustable and connected to the substrate 12 or the second snap-fit ​​part 11; the position of the limiting structure 13 is adjusted by external force so that the first clamping part 131 abuts against the second end 213 of the body 21, thereby limiting the snap-fit ​​structure 2.

[0041] like Figure 7As shown, in one alternative embodiment of this application, the limiting structure 13 includes a first assembly part 134 connected to a first clamping part 131; the second snap-fit ​​part 11 includes a snap-fit ​​wall 111 and a support wall 112 connected to the snap-fit ​​wall 111. The snap-fit ​​wall 111 is spaced a certain distance from the substrate 12. The snap-fit ​​wall 111 is provided with a snap-fit ​​groove 1111 that snaps into the second snap-fit ​​part 11. The support wall 112 is connected to the substrate 12. The support wall 112 is provided with multiple mounting positions. The distance between each mounting position and the snap-fit ​​wall 111 is different. The first assembly part 134 can be selectively mounted on the corresponding mounting position. By setting the limiting component on the appropriate mounting position, the first clamping part 131 abuts against the body 21, thereby ensuring that the limiting component stably limits the snap-fit ​​structure 2.

[0042] Specifically, the support wall 112 is provided with multiple recessed slots 1111 or slot holes, and the first assembly part 134 is provided with corresponding protruding and extending locking posts 1341, which can be selectively inserted into the slots 1111 or slot holes; alternatively, the support wall 112 is provided with protruding locking posts 1341, and the first assembly part 134 is provided with corresponding slots 1111 or slot holes; the end of the locking post 1341 is provided with a radially expanding first anti-detachment part 1342, and the groove wall of the slot 1111 is provided with a recessed first anti-detachment groove for accommodating the first anti-detachment part 1342, or the locking post 1341... The first anti-detachment portion 1342, located at the ends of the first clamping portion 131 and the clamping post 1341, is positioned on both sides of the support wall 112 through the locking hole. The first anti-detachment portion 1342 abuts against the corresponding side wall of the support wall 112. Preferably, the cross-sectional area of ​​the first anti-detachment portion 1342 gradually decreases along the insertion direction of the clamping post 1341. More preferably, the first anti-detachment portion 1342 is frustum-shaped or cone-shaped to reduce the resistance encountered by the first anti-detachment portion 1342 during insertion into the clamping slot 1111 or the locking hole. Another preferred embodiment is that the first anti-detachment portion 1342 is made of an elastic material.

[0043] like Figure 8 As shown, in another alternative embodiment of this application, the limiting component includes a second assembly part 135, which is connected to the first clamping part 131. At least one adjusting track is provided on the buckle base 1, extending towards the second end 213 of the body 21. The second assembly part 135 is movably connected to the adjusting track. The limiting component also includes a locking structure for locking or unlocking the second assembly part 135. Through the cooperation of the second assembly part 135 and the adjusting track, the limiting component can move under external force, causing the first clamping part 131 to move towards the second end 213 of the body 21 and abut against it. Then, the locking structure locks the second assembly part 135 in its current position, thereby ensuring that the first clamping part 131 stably limits the buckle structure 2. Preferably, the adjusting track extends along a first direction.

[0044] Specifically, the second engaging portion 11 includes an engaging wall 111 and a support wall 112 connected to the engaging wall 111. The engaging wall 111 is spaced a certain distance from the base plate 12. The engaging wall 111 has a slot 1111 for engaging with the second engaging portion 11. The support wall 112 is connected to the base plate 12. The support wall 112 has a recessed track groove, forming the adjustment track. The second assembly portion 135 has a movable protrusion extending into the track groove. The locking structure can be multiple stop ribs, each of which is rotatably connected to the support wall 112. The rotation axis of each stop rib is parallel to the extension direction of the track groove. Each stop rib is arranged on one side of the track groove along the extension direction of the track groove. The support wall 112 has a locking tongue on the other side of the track groove. Each locking tongue is detachably inserted into the locking hole on the free end of the corresponding stop rib; after the second assembly part 135 moves to the corresponding position and the first clamping part 131 abuts against the body 21, the first stop rib on the side of the second assembly part 135 facing the base rotates, causing the free end of the stop rib to move to the other side of the track groove and connect with the corresponding locking tongue, and the second assembly part 135 abuts against the stop rib; to lock the second assembly part 135 and prevent the second assembly part 135 from moving away from the body 21; preferably, a radially expanding second anti-detachment part 1342 is provided on the extended end of the movable protrusion, and a correspondingly concave second anti-detachment groove 1361 is provided on the two side walls of the track groove; to prevent the second assembly part 135 from detaching from the track groove.

[0045] like Figure 8 As shown, in another specific case, an adjusting rod 136 is provided on the base plate 12 of the snap-fit ​​base 1. The adjusting rod 136 extends from the base plate 12 toward the second end 213 near the body 21, forming an adjusting track. The second assembly part 135 is movably sleeved on the adjusting rod 136. A plurality of recessed locking grooves are provided on the peripheral wall of the adjusting rod 136. Each locking groove is arranged along the extension direction of the adjusting rod 136. The second assembly part 135 is provided with at least one through hole. The locking structure can be a locking rod 137. The locking rod 137 passes through the through hole into the second assembly part 135 and is inserted into the corresponding locking groove. When the second assembly part 135 moves to the corresponding position, at least one through hole of the second assembly part 135 is aligned with the corresponding locking groove. By inserting the locking rod 137, the locking rod 137 is inserted into the corresponding locking groove to lock the second assembly part 135 and prevent the second assembly part 135 from moving away from the snap-fit ​​wall 111.

[0046] The above alternative embodiments propose various implementation methods. Although they can achieve the purpose of adjusting the position of the first clamping part 131 to abut against the body 21 and improving the assembly stability of the buckle structure 2 and the buckle base 1, the overall movable design of the limiting structure 13 is relatively complex, making the assembly of the buckle base 1 more complicated. Furthermore, the arrangement of the various structures is relatively cramped, and adjusting the limiting structure 13 requires manual operation by the operator, making it inconvenient to adjust the position of the first clamping part 131. Therefore, the following preferred embodiment is proposed; Figures 1 to 6 As shown, in a preferred embodiment of this application, the limiting structure 13 includes an elastically deformable connecting portion 132. The connecting end of the connecting portion 132 is connected to the substrate 12, and the free end is provided with a first clamping portion 131. The connecting portion 132 deforms by releasing stored force, causing the first clamping portion 131 to abut against the second end 213 of the body 21.

[0047] With the above configuration, by causing the connecting part 132 to elastically deform itself, during the process of the first latching part 211 latching the second latching part 11, the connecting part 132 elastically deforms and stores force, driving the first clamping part 131 away from the second latching part 11, so as to form a channel for the second end 213 of the body 21 to pass through. After the first latching part 211 completes the latching, the connecting part 132 releases the stored force and rebounds, driving the first clamping part 131 to adaptively adjust its position, so that the first clamping part 131 stably abuts against the second end 213 of the body 21, making the position adjustment of the first clamping part 131 more convenient. In addition, the connecting part 132 can provide elastic force to the first clamping part 131, which can further improve the static friction force parallel to the abutting surface direction, and further improve the stability of the latching structure 2 and the latching base 1. In addition, the connecting part 132 can be fixedly connected to the substrate 12 or integrally formed. Compared with the movable connection method, the connection method between the connecting part 132 and the substrate 12 is simpler and more reliable.

[0048] In an alternative embodiment of this application, the connecting part 132 extends along a first direction and, through telescopic deformation, drives the first clamping part 131 to clamp onto the end face of the second end 213 of the body 21; preferably, the connecting part 132 is a combination of one or more of a spring, a hydraulic rod, and a pneumatic rod.

[0049] Although the connecting part 132 in the above alternative embodiments can achieve the purpose of moving the first clamping part 131 through its own deformation, the telescopic connecting part 132 usually requires a certain installation space to ensure its normal telescopic movement and elastic function. Within the limited space of the snap-fit ​​base 1, the installation of the telescopic connecting part 132 is restricted. Therefore, the preferred embodiment of this application is proposed, in which the extension direction of the connecting part 132 forms an angle with the first direction, and the first clamping part 131 abuts against the second end 213 of the body 21 through bending deformation. The space occupied by the bending deformation of the connecting part 132 is relatively small, enabling the function of moving the first clamping part 131 in a more compact space. This is beneficial for the miniaturization and integration design of the snap-fit ​​base 1, meeting the needs of application scenarios with high space requirements.

[0050] In one embodiment of this application, the connecting part 132 can be detachably connected to the base plate 12; so that a new limiting structure 13 can be replaced when the limiting structure 13 is damaged, which reduces maintenance costs compared to replacing the entire buckle base 1; the connecting part 132 is connected to the buckle base 1 by one or more combinations of snap-fit, screw, rivet, etc.

[0051] In another embodiment of this application, the first clamping part 131 and the connecting part 132 are integrally formed to facilitate the production and processing of the buckle base 1, and the step of connecting the limiting structure 13 and the base plate 12 can be omitted when assembling the buckle assembly, thereby improving the overall efficiency of vehicle assembly.

[0052] In an embodiment of this application, the connecting portion 132 includes a first segment extending from the substrate 12 along a first direction, and a second segment connected to the extension end of the first segment, the second segment being bent and extended in a second direction.

[0053] By configuring the second segment so that its extension direction is the same as the snap-fit ​​direction of the first snap-fit ​​part 211, the connecting part 132 can guide the second end 213 of the body 21 to move accurately to the appropriate position along a predetermined path, reducing deviations and errors during installation and improving the accuracy and efficiency of assembly. Simultaneously, during assembly, there is no need for complex positioning and adjustment operations on the connecting part 132; simply move the snap-fit ​​structure 2 along the second direction and snap it into the second snap-fit ​​part 11, so that the second end 213 of the body 21 abuts against the second segment of the connecting part 132. The first clamping part 131 is moved adaptively away from the first snap-fit ​​part 211, forming an installation channel for the second end 213 of the body 21 to enter. After the snap-fit ​​structure 2 moves to the appropriate position, the connecting part 132 can adaptively spring back, causing the first clamping part 131 to move in the opposite direction and abut against the second end 213 of the body 21. The assembly process of the snap-fit ​​structure 2 and the snap-fit ​​base 1 is simplified without the need for the operator to manually move the first clamping part 131, which reduces the assembly difficulty and the operator's operation requirements and is conducive to large-scale production.

[0054] In the embodiments of this application, the second section of the connecting part 132 is smoothly bent and extended; so that the surface of the connecting part 132 in contact with the snap-fit ​​structure 2 is smoother, reducing the wear degree of the snap-fit ​​structure 2 during the installation process, and reducing the defect rate of the snap-fit ​​structure 2 during the assembly process to a certain extent.

[0055] In the embodiments of this application, a clearance opening 121 is provided on the substrate 12, and the clearance opening 121 is directly opposite the clamping part in a first direction.

[0056] With the above configuration, the first clamping part 131 needs to have a certain travel distance under the drive of the connecting part 132 to complete the clamping and releasing action of the second end 213 of the body 21. By setting the clearance opening 121 facing the first clamping part 131, sufficient space is provided for the movement of the first clamping part 131, ensuring that the first clamping part 131 can move fully to the appropriate position to achieve the purpose of stable contact with the second end 213 of the body 21. This reduces the space requirements of the limiting component between the second clamping part 23 and the substrate 12, and is more conducive to the miniaturization and integration design of the snap-on base 1.

[0057] In the embodiments of this application, the clearance opening 121 is located around the connecting portion 132; preferably, the peripheral wall of the clearance opening 121 is flush with the side wall of the connecting portion 132 on the second direction side.

[0058] like Figures 1 to 8 As shown in the embodiment of this application, the second snap-fit ​​portion 11 includes a snap-fit ​​wall 111 and a support wall 112 connected to the snap-fit ​​wall 111. The snap-fit ​​wall 111 is disposed at a certain distance from the substrate 12. The snap-fit ​​wall 111 is provided with a snap-fit ​​groove 1111 that snaps into the first snap-fit ​​portion 211. The support wall 112 is connected to the substrate 12. The second end 213 of the body 21 protrudes from the wall surface of the snap-fit ​​wall 111 and extends toward the substrate 12.

[0059] In the embodiments of this application, the support wall 112 extends from the snap-fit ​​wall 111 along a first direction toward the substrate 12, and the snap-fit ​​wall 111 is perpendicular to the support wall 112.

[0060] In the embodiments of this application, the snap-fit ​​wall 111 is provided with a recessed snap-fit ​​groove on the reverse side portion in the second direction, and the first snap-fit ​​portion 211 is snapped into the snap-fit ​​groove along the second direction; preferably, the snap-fit ​​groove gradually expands from the groove opening to the groove bottom; specifically, the groove opening width of the snap-fit ​​groove is slightly smaller than the diameter of the first snap-fit ​​portion 211, so that when the snap-fit ​​structure 2 is installed, the groove wall at the groove opening can limit the neck segment, improve the stability of the snap-fit ​​structure 2 and the snap-fit ​​base 1 assembly, and further prevent the snap-fit ​​structure 2 from falling out.

[0061] In the embodiments of this application, the support wall 112 surrounds the periphery of the snap-fit ​​wall 111; preferably, the support wall 112 extends from one side of the snap-fit ​​groove opening around the periphery of the snap-fit ​​wall 111 to the other side of the snap-fit ​​groove; the gap area between the two ends of the support wall 112 forms a communication port 1121 communicating with the snap-fit ​​groove 1111; so that when the first snap-fit ​​part 211 snaps into the snap-fit ​​groove, the second end 213 of the body 21 moves through the communication port 1121 to the space between the snap-fit ​​wall 111 and the substrate 12.

[0062] In the embodiments of this application, the support wall 112 is provided with a plurality of reinforcing portions with protruding surfaces, and each reinforcing portion is connected to the substrate 12 respectively; preferably, each reinforcing portion is arranged along the edge of the support wall 112 near the substrate 12; so as to improve the connection strength between the support wall 112 and the substrate 12 and prevent the support wall 112 from tilting and causing the snap-fit ​​wall 111 to shift position.

[0063] In the embodiments of this application, the second snap-fit ​​portion 11 includes a snap-fit ​​wall 111 and a support wall 112 connected to the snap-fit ​​wall 111. The snap-fit ​​wall 111 is disposed at a certain distance from the substrate 12. The snap-fit ​​wall 111 is provided with a snap-fit ​​groove 1111 for snapping with the second snap-fit ​​portion 11. The support wall 112 is connected to the substrate 12. The snap-fit ​​structure 2 includes a mounting portion 22, which is disposed on the second end 213 of the body 21. The mounting portion 22 contacts the corresponding side surface of the snap-fit ​​wall 111. The mounting portion 22 is clamped between the first clamping portion 131 and the snap-fit ​​wall 111.

[0064] By setting up the mounting part 22, the reverse offset of the main body 21 in the first direction is prevented from causing the snap-fit ​​structure 2 to detach from the snap-fit ​​base 1. By making the first clamping part 131 contact the mounting part 22, the contact area between the first clamping part 131 and the snap-fit ​​structure 2 is increased, thereby improving the stability of the contact.

[0065] like Figures 5 to 8 As shown in the embodiments of this application, at least one protruding or recessed limiting part 133 is provided on the first clamping part 131, and an assembly part 212 that cooperates with the limiting part 133 is provided on the second end 213 of the body 21.

[0066] With the above configuration, after the first clamping part 131 and the body 21 complete the contact action, the limiting part 133 is embedded in the assembly part 212, or the assembly part 212 is embedded in the limiting part 133, forming a mechanical interlocking structure. This tight fit can effectively prevent the buckling structure 2 from loosening or falling off from the buckling base 1 under vibration, external force pulling, etc., and can ensure that the buckling structure 2 is always firmly connected to the buckling base 1, without any abnormal noise or falling off, thus improving the reliability and stability of the connection.

[0067] Meanwhile, the cooperation between the limiting part 133 and the assembly part 212 provides precise positioning for the installation of the snap-fit ​​structure 2. During the process of snapping the snap-fit ​​structure 2 onto the second clamping part 23, the operator can quickly and accurately judge whether the snap-fit ​​structure 2 is installed in the correct position by observing or feeling the alignment between the limiting part 133 and the assembly part 212. This helps to improve the assembly quality and consistency of the snap-fit ​​components and reduce performance problems or failures caused by installation deviations.

[0068] In the embodiments of this application, the protrusion or recess direction of the limiting part 133 is parallel to the first direction, and the recess or protrusion direction of the assembly part 212 is also parallel to the first direction.

[0069] In an alternative embodiment of this application, the limiting part 133 protrudes from the surface of the first clamping part 131, and the assembly part 212 is recessed in the end face of the second end 213 of the body 21; multiple limiting parts 133 are correspondingly provided, all extending into the same assembly part 212 and arranged circumferentially along the assembly part 212; or, the limiting part 133 is recessed in the surface of the first clamping part 131, and the assembly part 212 protrudes from the end face of the second end 213 of the body 21; multiple assembly parts 212 are correspondingly provided, all extending into the same limiting part 133 and arranged circumferentially along the limiting part 133.

[0070] However, for the above-mentioned scheme of a groove with multiple protrusions, the protrusions may have relative movement space within the groove. When subjected to external forces such as pulling or vibration, the protrusions are prone to relative movement with the groove, causing the first clamping part 131 and the body 21 to shake perpendicular to the first direction. Therefore, the preferred embodiment of this application is proposed, wherein the assembly part 212 and the limiting part 133 are provided in a one-to-one correspondence, and the peripheral sidewall of the limiting part 133 is in close contact with the peripheral sidewall of the assembly part 212. Preferably, the first clamping part 131 is provided with at least one limiting part 133, and the same number of assembly parts 212 are provided on the end face of the second end 213 of the body 21.

[0071] Through the above-mentioned design, a precise mechanical interlock can be achieved by a one-to-one correspondence and a design with closely fitting sidewalls. This ensures that each limiting part 133 is tightly fitted with the corresponding assembly part 212, forming effective constraints in all directions perpendicular to the first direction. This further enhances the stability of the assembly between the snap-fit ​​structure 2 and the snap-fit ​​base 1. At the same time, the close fitting of the sidewalls allows stress to be evenly distributed between the limiting part 133 and the assembly part 212. When subjected to external forces, stress will not be concentrated at a certain point or in a local area, thereby improving the load-bearing capacity and impact resistance of the snap-fit ​​assembly.

[0072] In the embodiments of this application, at least two assembly parts 212 are provided on the second end 213 of the body 21, and the same number of limiting parts 133 are provided on the first clamping part 131. At least two assembly parts 212 are distributed non-centrally symmetrically on the end face of the second end 213 of the body 21. Sometimes, the side wall of a certain side of the snap-fit ​​structure 2 needs to be oriented towards the corresponding orientation to meet the installation requirements. However, adjusting the orientation will affect the assembly efficiency. By distributing the assembly parts 212 non-centrally symmetrically, a unique positioning feature is provided for the installation process. When installing, the staff can quickly and accurately determine the orientation and position of the corresponding side wall of the snap-fit ​​structure 2 based on the specific positional relationship between the assembly parts 212 and the limiting parts 133, thereby avoiding installation misalignment caused by incorrect orientation and improving installation efficiency.

[0073] In the embodiments of this application, at least one assembly part 212 is located at the center of the end face of the second end 213 of the body 21.

[0074] With the above configuration, the assembly force between the first clamping part 131 and the body 21 can be evenly distributed in the central area of ​​the end face of the second end 213 of the body 21. When the buckle assembly is subjected to external force, this uniform force distribution can effectively prevent the body 21 from deflection or twisting due to uneven force, thereby enhancing the balance and stability of the entire buckle connection.

[0075] In the embodiments of this application, the assembly part 212 is a groove-shaped part recessed into the body 21 from the second end 213 end face of the body 21. The projection of the groove-shaped assembly part 212 in the second direction coincides with the first snap-fit ​​part 211 of the body 21. Specifically, the limiting part 133 protrudes from the surface of the first clamping part 131, and the protruding end face of the limiting part 133 is spaced a certain distance from the bottom of the groove of the groove-shaped assembly part 212. So that during the process of the first snap-fit ​​part 211 snapping onto the second snap-fit ​​part 11, the body 21 can pass through... The compression assembly 212 adaptively reduces the size of the first snap-fit ​​part 211, allowing the first snap-fit ​​part 211 to smoothly snap onto the second snap-fit ​​part 11. After the snap-fit ​​is completed, the body 21 returns to its original shape, and the limiting part 133 is inserted into the restored assembly 212 and supports the peripheral sidewall of the assembly 212. This makes it more difficult for the body 21 to shrink the size of the first snap-fit ​​part 211 through compression deformation and detach from the second snap-fit ​​part 11, thereby improving the snap-fit ​​strength between the first snap-fit ​​part 211 and the second snap-fit ​​part 11.

[0076] like Figures 1 to 8 As shown in the embodiments of this application, the buckle structure 2 includes a second clamping part 23, which is disposed on the body 21 and located between the first snap-fit ​​part 211 and the first end. The second clamping part 23 abuts against the second snap-fit ​​part 11.

[0077] With the above configuration, the second clamping part 23 abuts against the second snap-fit ​​part 11 to further prevent the snap-fit ​​structure 2 from shifting in the first direction.

[0078] Furthermore, when the mounting part 22 is provided on the second end 213 of the main body 21, the first clamping part 131 and the second snap-fit ​​part 11 of the snap-fit ​​base 1 are clamped on both sides of the mounting part 22, and the second clamping part 23 and the mounting part 22 of the snap-fit ​​structure 2 are clamped on both sides of the second snap-fit ​​part 11, forming a double clamping mechanism, which greatly enhances the connection stability between the snap-fit ​​structure 2 and the snap-fit ​​base 1. During vehicle operation, continuous and complex vibrations will occur. The double clamping can effectively prevent the snap-fit ​​structure 2 from loosening or falling off from the snap-fit ​​base 1, ensuring that the corresponding two parts are firmly connected and reducing abnormal noise caused by connection problems.

[0079] In one embodiment of this application, the second clamping part 23 is a strip-shaped structure that extends from the outer peripheral wall of the body 21 toward the snap-fit ​​wall 111, and the extended end of the second clamping part 23 abuts against the second clamping part 23; preferably, at least two second clamping parts 23 are provided and are equidistantly distributed along the circumference of the body 21.

[0080] In another preferred embodiment of this application, the second clamping portion 23 is annular, and the second clamping portion 23 includes an inner ring portion and an outer ring portion disposed on the outer periphery of the inner ring portion. The inner ring portion extends from the inner periphery to the outer periphery in a direction close to the second clamping portion 23, and the outer ring portion extends from the inner periphery to the outer periphery in a direction away from the second clamping portion 23. The contact area between the inner ring portion and the outer ring portion abuts against the second clamping portion 23.

[0081] This application also provides a vehicle, including: a first component; a second component; and the above-mentioned buckle assembly, wherein at least one of the buckle bases 1 is connected to the second component, and the second component is connected to the corresponding first component through a buckle structure 2 on the buckle base 1.

[0082] In the vehicle of this application, the same beneficial effects can be achieved by including the snap-fit ​​assembly in the above embodiments. That is, by providing a limiting structure 13 on the snap-fit ​​base 1 and making the position of the first clamping part 131 adjustable, the first clamping part 211 can be easily snapped into place with the second clamping part 11, while the first clamping part 131 can be stably limited to the second end 213 of the body 21, preventing the snap-fit ​​structure 2 from shaking or moving towards the substrate 12. In addition, by adjusting the position of the first clamping part 131 so that the first clamping part 131 abuts against the body 21, a static friction force perpendicular to the first direction is generated, preventing the first snap-fit ​​structure 2 from disengaging from the second snap-fit ​​structure 2 in the reverse direction of the second direction. This improves the assembly strength between the snap-fit ​​structure 2 and the snap-fit ​​base 1, thereby improving the connection strength and stability between the second component and the first component, and effectively preventing the separation of the first component and the second component.

[0083] In the embodiments of this application, the second component is an interior or exterior trim part of the vehicle, and the first component is a component with high structural strength, such as sheet metal; wherein, the second component may be a component with a large volume, including door panels, pillar trim panels, roof, etc., and the second component is connected to the first component through multiple snap-fit ​​components.

[0084] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
