Description

Technical Field

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

[0002] In the automotive manufacturing industry, snap-fit ​​connections are widely used in connecting automotive interior parts, exterior parts, and chassis accessories due to their advantages such as eliminating the need for additional fasteners, high assembly efficiency, and reducing vehicle weight.

[0003] In the prior art, the buckle includes a locking plate and an elastic latch disposed on the locking plate. The elastic latch extends to one side of the locking plate and can engage with the skeleton of the corresponding locking slot to achieve engagement.

[0004] However, in practical applications, the one-way snap-fit ​​structure used in automobiles can experience insufficient connection stability due to factors such as vibrations during vehicle operation, external impacts under complex working conditions, and long-term wear and tear. Because the latch only extends from one side of the latch plate, it can only provide engagement force from one side. When the vehicle is driving on bumpy roads or encounters external collisions, the snap-fit ​​is prone to uneven force distribution, leading to loosening or even detachment. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a snap-fit ​​structure and vehicle, which achieves snap-fit ​​from both sides of the snap-fit ​​plate through a first snap-fit ​​component and a second snap-fit ​​component. Compared with the traditional single-sided snap-fit ​​structure where only one side is subjected to force, this bidirectional snap-fit ​​design can significantly improve the connection stability, effectively avoid problems such as snap-fit ​​loosening and disengagement, and simplify the assembly process, achieving a reliable connection without the need for additional fasteners, thus balancing assembly efficiency and connection reliability.

[0007] To achieve the above objectives, in a first aspect, this application provides a snap-fit ​​structure, comprising: The first card component includes: skeleton; A slot that extends through the frame; The second card includes: ontology; A card plate, which is vertically disposed on one side of the body; the two sides of the card plate are a first side and a second side, respectively; A receiving cavity that extends through the card plate; A first latch is disposed in the receiving cavity, the first latch extends toward the first side, and the first latch is used to abut against the skeleton; The second latch is disposed within the receiving cavity and extends to the second side, and is used to abut against the skeleton.

[0008] In this technical solution, a first and a second locking element are used to achieve engagement from both sides of the locking plate. When connecting the first and second locking elements, the locking plate passes through the locking groove. During this process, the first and second locking tongues undergo elastic deformation until they pass through the groove. The first and second locking tongues then spring back and abut against the side wall of the frame, thus achieving engagement. Compared to traditional single-sided locking structures where only one side is subjected to force, this bidirectional locking design significantly improves connection stability. It is particularly suitable for scenarios where vehicles are subject to vibration and impact during operation, effectively preventing problems such as loosening or detachment of the locking elements. Simultaneously, it simplifies the assembly process, achieving a reliable connection without the need for additional fasteners, thus balancing assembly efficiency and connection reliability.

[0009] In some embodiments of this application, the first latch includes: A first tongue plate is connected to the side of the receiving cavity away from the body, and the first tongue plate extends toward the body; A first latching portion is disposed at the end of the first tongue plate. The first latching portion includes a first guide surface, which is inclined to a first side from the direction toward the body. The first guide surface extends to a first side of the latch plate.

[0010] In this technical solution, the first tongue plate extends into the body to provide excellent elastic deformation capability. During installation, the first guide surface contacts the edge of the slot, continuing to push the first and second locking components. Guided by the first guide surface, the first tongue plate undergoes elastic deformation, bending towards the second side. After the first engaging portion has completely passed through the slot, the first tongue plate returns to its original shape, allowing the side of the first engaging portion away from the first tongue plate to abut against the frame. The first guide surface facilitates the automatic deformation of the first tongue plate, reducing resistance and difficulty during installation.

[0011] In some embodiments of this application, the second latch includes: The second tongue plate is connected to the side of the receiving cavity away from the body, and the second tongue plate extends toward the body; The second latching portion is disposed at the end of the second tongue plate. The second latching portion includes a second guide surface, which is inclined from the direction toward the body to a second side and extends to the second side of the latch plate.

[0012] In this technical solution, the second tongue plate extends into the body to provide it with good elastic deformation capability. During installation, the second guide surface contacts the edge of the slot, and the first and second clips are then installed. Guided by the second guide surface, the second tongue plate undergoes elastic deformation, bending towards the first side. After the second engagement portion has completely passed through the slot, the second tongue plate returns to its original shape, allowing the side of the second engagement portion away from the second tongue plate to abut against the frame. The second guide surface facilitates the automatic deformation of the second tongue plate, reducing resistance and difficulty during installation.

[0013] In some embodiments of this application, the first latch has a third guide surface on the side facing the body, and the third guide surface is inclined from the direction away from the body toward the first side; The second latch has a fourth guide surface on the side facing the body, and the fourth guide surface is inclined towards the second side from the direction away from the body.

[0014] In the original technical solution, after the first and second clips are installed, if both the first and second latching parts are in planar contact with the frame, and if the first and second latching tongues cannot be reached in a narrow space, separation of the first and second clips is impossible, requiring forced damage. However, in this application, after installation, the third and fourth guide surfaces can form a certain angle with the corresponding sidewalls of the frame. When disassembly is required, forcefully separating the first and second clips causes the first tongue to deform towards the second side and the second tongue to deform towards the first side, allowing the first and second latching parts to pass through the slot in the opposite direction to their installation direction, thus separating the first and second clips and enabling reuse.

[0015] In some embodiments of this application, a gap exists between the first latch and the second latch.

[0016] In this technical solution, the gap between the first and second latches ensures that, during installation, the first and second latches can bend and deform in completely opposite directions, achieving a locking function. Furthermore, this gap prevents interference between the first and second latches during deformation, reducing wear and improving the smoothness of installation.

[0017] In some embodiments of this application, the side of the first latch away from the second latch has a gap with the sidewall corresponding to the receiving cavity; The side of the second latch away from the first latch has a gap with the sidewall corresponding to the receiving cavity.

[0018] In this technical solution, a gap is used to ensure that the first and second tongue plates can deform and bend normally, achieving the snap-fit ​​function. Furthermore, this gap prevents interference between the first and second tongue plates and the locking plates during deformation, reducing wear and improving the smoothness of installation.

[0019] In some embodiments of this application, a first clearance groove is provided on the card slot corresponding to the second side of the card plate, and the first clearance groove corresponds to the first tongue plate; When the first latch passes through the latch groove, the first clearance groove is used for the first latch to pass through; A second clearance groove is provided on the card slot corresponding to the first side of the card plate, and the second clearance groove corresponds to the second tongue plate; When the second latch passes through the latch groove, the second clearance groove is used for the passage of the second latch.

[0020] In the technical solution, during the insertion of the card plate into the card slot, the first and second latches undergo elastic deformation due to contact with the frame. Therefore, a portion of the first latch will briefly be located on the second side of the card plate, and a portion of the second latch will briefly be located on the first side. At this time, the first clearance groove allows the first latch extending to the second side to pass through; the second clearance groove allows the second latch extending to the first side to pass through, ensuring that the first and second latches can smoothly pass through the card slot, completing the engagement of the first and second card components.

[0021] In some embodiments of this application, limiting ribs are provided on both the first and second sides of the card plate, and the limiting ribs are used to abut against the inner wall of the card slot; The height direction of the limiting rib is away from the clamping plate; The height of the limiting rib gradually increases from the direction closer to the body.

[0022] In this technical solution, after the first and second locking components are connected, the limiting rib fills the gap between the locking plate and the locking slot. This means the limiting component provides support between the locking plate and the locking slot, ensuring the locking plate remains positioned within the slot. This prevents the locking plate from becoming too close to one side of the slot due to insufficient support, which could cause the locking tongue on the other side to detach from the frame support. This improves the stability of the connection.

[0023] In some embodiments of this application, the two ends of the card plate on the side away from the body are chamfered.

[0024] In this technical solution, the chamfered design eliminates the sharp edges of the pallet's ends. On one hand, it provides initial guidance during assembly, helping the pallet quickly align with the slot entrance and reducing assembly delays caused by the sharp edges, thus improving assembly efficiency. On the other hand, it prevents operators from being scratched by sharp edges during assembly and maintenance, enhancing operational safety. Simultaneously, the chamfered structure reduces collisions and friction between the pallet and the slot edge when inserted, minimizing wear on both.

[0025] In addition, this application also provides a vehicle that employs the above-described snap-fit ​​structure; the frame is part of a vehicle component; and the body is part of another vehicle component.

[0026] In the technical solution, vehicles using this snap-fit ​​structure can have their two corresponding vehicle components tightly connected, avoiding separation caused by long-term vibration, external impact, and other harsh working conditions, thus maintaining a reliable connection.

[0027] As can be seen from the above technical solutions, additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. It should be noted that in the automotive industry, specifically in the automotive manufacturing sector, snap-fit ​​connections are widely used in connecting automotive interior parts, exterior parts, and chassis accessories due to their advantages such as eliminating the need for additional fasteners, high assembly efficiency, and reducing vehicle weight.

[0032] In the prior art, the buckle includes a locking plate and an elastic latch disposed on the locking plate. The elastic latch extends to one side of the locking plate and can engage with the skeleton of the corresponding locking slot to achieve engagement.

[0033] However, in practical applications, the one-way snap-fit ​​structure used in automobiles can experience insufficient connection stability due to factors such as vibrations during vehicle operation, external impacts under complex working conditions, and long-term wear and tear. Because the latch only extends from one side of the latch plate, it can only provide engagement force from one side. When the vehicle is driving on bumpy roads or encounters external collisions, the snap-fit ​​is prone to uneven force distribution, leading to loosening or even detachment.

[0034] Based on this, this application proposes a snap-fit ​​structure and vehicle, which achieves snap-fit ​​from both sides of the snap-fit ​​plate through a first snap-fit ​​component and a second snap-fit ​​component. Compared with the traditional single-sided snap-fit ​​structure that only bears force on one side, this bidirectional snap-fit ​​design can significantly improve the connection stability, effectively avoid problems such as snap-fit ​​loosening and detachment, and simplify the assembly process, achieving a reliable connection without additional fasteners, thus balancing assembly efficiency and connection reliability.

[0035] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0036] Please refer to all the accompanying drawings. In one illustrative embodiment of the snap-fit ​​structure and vehicle of this application, the snap-fit ​​structure includes a first snap-fit ​​member and a second snap-fit ​​member. The first snap-fit ​​member includes a frame 100. The frame 100 can be part of a structural component. For example, if a component needs to be connected to a vehicle body, the frame 100 can be part of the vehicle body or part of a component.

[0037] In some embodiments, the first card further includes a card slot 101 that extends through the frame 100. The card slot 101 is used for partial insertion of the second card, thereby connecting the first card and the second card.

[0038] In some embodiments, the second fastener includes a body 200. The body 200 may be part of a structural component, for example, where a component needs to be connected to a vehicle body, the frame 100 is part of the vehicle body, and the body 200 is part of the component; or, the body 200 may be part of the vehicle body, and the frame 100 may be part of the body 200.

[0039] However, it is understandable that the body 200 and the skeleton 100 cannot be located on the same structural component.

[0040] In some embodiments, the second card also includes a card plate 300, which is vertically disposed on one side of the body 200; the card plate 300 is used to pass through the card slot 101 on the frame 100.

[0041] In some embodiments, the two sides of the card plate 300 are a first side and a second side, respectively; the second card also includes a receiving cavity, a first latch 400 and a second latch 500. The receiving cavity extends through the card plate 300; the first latch 400 is disposed in the receiving cavity, extends to the first side, and abuts against the skeleton 100; the second latch 500 is disposed within the receiving cavity, extends to the second side, and abuts against the skeleton 100.

[0042] This application achieves a snap-fit ​​connection from both sides of the locking plate 300 through the above-described scheme using a first and a second locking component. When connecting the first and second locking components, the locking plate 300 passes through the locking groove 101. During this passage, the first and second locking tongues 400 and 500 undergo elastic deformation until they pass through the locking groove 101. The first and second locking tongues then spring back and abut against the side wall of the frame 100, thus achieving the snap-fit ​​connection. Compared to traditional single-sided snap-fit ​​structures where only one side is subjected to force, this bidirectional snap-fit ​​design significantly improves connection stability, making it particularly suitable for scenarios where vehicles need to withstand vibration and impact during operation. It effectively avoids problems such as loosening or detachment of the snap-fit, while simplifying the assembly process, achieving a reliable connection without the need for additional fasteners, thus balancing assembly efficiency and connection reliability.

[0043] In some embodiments, the first latch 400 includes a first tongue plate 401, which is connected to the side of the receiving cavity away from the body 200 and extends toward the body 200. The first tongue plate 401 extends toward the body 200 to give it good elastic deformation capability.

[0044] In some embodiments, the first latch 400 further includes a first engaging portion 402, which is disposed at the end of the first latch plate 401. The first engaging portion 402 is used to abut against the frame 100 after passing through the latch groove 101 to achieve engagement.

[0045] Furthermore, the first engaging portion 402 includes a first guide surface 403, which is inclined towards a first side from the direction toward the body 200; the first guide surface 403 extends to the first side of the locking plate 300. During installation, the first guide surface 403 contacts the edge of the locking groove 101, continuing to push and install the first and second locking components. Under the guidance of the first guide surface 403, the first tongue plate 401 will undergo elastic deformation by bending towards a second side. After the first engaging portion 402 has completely passed through the locking groove 101, the first tongue plate 401 will return to its original shape, so that the side of the first engaging portion 402 away from the first tongue plate 401 abuts against the frame 100. The first guide surface 403 facilitates the automatic deformation of the first tongue plate 401, reducing the resistance and difficulty encountered during installation.

[0046] In some embodiments, the second latch 500 includes a second tongue plate 501, which is connected to the side of the receiving cavity away from the body 200 and extends toward the body 200. The second tongue plate 501 extends toward the body 200 to give it good elastic deformation capability.

[0047] In some embodiments, the second latch 500 further includes a second latching portion 502, which is disposed at the end of the second tongue plate 501. The second latching portion 502 is used to abut against the skeleton 100 after passing through the latching groove 101 to achieve latching.

[0048] Furthermore, the second engaging portion 502 includes a second guide surface 503, which is inclined towards a second side from the direction toward the body 200 and extends to the second side of the locking plate 300. During installation, the second guide surface 503 contacts the edge of the locking groove 101, and the first and second locking pieces are then installed. Under the guidance of the second guide surface 503, the second tongue plate 501 undergoes an elastic deformation, bending towards the first side. After the second engaging portion 502 has completely passed through the locking groove 101, the second tongue plate 501 returns to its original shape, so that the side of the second engaging portion 502 away from the second tongue plate 501 abuts against the frame 100. The second guide surface 503 facilitates the automatic deformation of the second tongue plate 501, reducing the resistance and difficulty encountered during installation.

[0049] In some embodiments, the card plate 300 is a rectangular plate, and the receiving cavity is rectangular. The first latch 400 and the second latch 500 are parallel, and the lengths of the first latch 400 and the second latch 500 are the same to ensure that the first latching portion 402 and the second latching portion 502 are at the same distance from the body 200. This ensures that after the card plate 300 is inserted into the card slot 101, the first latching portion 402 and the second latching portion 502 can simultaneously abut against the frame 100, preventing wobbling between the first and second latching components.

[0050] In some embodiments, the first latch 400 has a third guide surface 404 on the side facing the body 200, and the third guide surface 404 is inclined toward the first side from the direction away from the body 200.

[0051] In some embodiments, the second latch 500 has a fourth guide surface 504 on the side facing the body 200, and the fourth guide surface 504 is inclined toward the second side from the direction away from the body 200.

[0052] It is understandable that after the first and second clips are installed, if the first clip 402 and the second clip 502 are in planar contact with the frame 100, and if the first clip tongue 400 and the second clip tongue 500 cannot be reached in a narrow space, the first and second clips cannot be separated. In this case, the first and second clips can only be forcibly damaged.

[0053] Therefore, this application has a third guide surface 404 and a fourth guide surface 504. After installation, the third guide surface 404 and the fourth guide surface 504 can form a certain angle with the side wall corresponding to the frame 100. When disassembly is required, the first and second clips are separated by force. Under the action of the third guide surface 404, the first tongue plate 401 will deform to the second side, and the second tongue plate 501 will deform to the first side, so that the first snap-fit ​​part 402 and the second snap-fit ​​part 502 pass through the slot 101 in the opposite direction to the installation, thereby realizing the separation of the first and second clips and enabling reuse.

[0054] In some embodiments, a gap exists between the first latch 400 and the second latch 500. This gap ensures that, during installation, the first latch 400 and the second latch 500 can bend and deform in completely opposite directions, achieving a snap-fit ​​function. Furthermore, this gap prevents interference between the first latch 400 and the second latch 500 during deformation, reducing wear and improving the smoothness of installation.

[0055] In some embodiments, the side of the first latch 400 away from the second latch 500 has a gap with the sidewall corresponding to the receiving cavity. This gap ensures that the first latch plate 401 can deform and bend normally, achieving the latching function. Furthermore, this gap prevents the first latch 400 from interfering with the latch plate 300 during deformation, reducing wear and improving the smoothness of installation.

[0056] In some embodiments, the side of the second latch 500 away from the first latch 400 has a gap with the sidewall corresponding to the receiving cavity. This gap ensures that the second latch 501 can deform and bend normally, achieving the snap-fit ​​function. Furthermore, this gap prevents the second latch 500 from interfering with the latch plate 300 during deformation, reducing wear and improving the smoothness of installation.

[0057] In some embodiments, a first clearance groove 102 is provided on the card slot 101 corresponding to the second side of the card plate 300, and the first clearance groove 102 corresponds to the first tongue plate 401; when the first tongue 400 passes through the card slot 101, the first clearance groove 102 is used for the first tongue 400 to pass through.

[0058] Specifically, the slot 101 is a rectangular slot. After the first and second locking components are connected, a first clearance groove 102 is formed on the side wall of the slot 101 located on the second side of the locking plate 300. The clearance groove is only located in the area of ​​the first latch 400, ensuring that while the first latch 400 passes through, the second latch 500 can contact the frame 100 to achieve locking.

[0059] During the insertion of the card plate 300 into the card slot 101, the first latch 400 and the second latch 500 will undergo elastic deformation due to contact with the skeleton 100. Therefore, a portion of the first latch 400 will be temporarily located on the second side of the card plate 300. At this time, the first clearance groove 102 allows the first latch 401 extending to the second side to pass through, ensuring that the first latch 400 can smoothly pass through the card slot 101 and complete the engagement of the first and second card pieces.

[0060] In some embodiments, a second clearance groove 103 is provided on the card slot 101 corresponding to the first side of the card plate 300, and the second clearance groove 103 corresponds to the second tongue plate 501; when the second tongue 500 passes through the card slot 101, the second clearance groove 103 is used for the second tongue 500 to pass through.

[0061] Specifically, the slot 101 is a rectangular slot. After the first and second locking components are connected, a second clearance slot 103 is formed on the side wall of the slot 101 located on the first side of the locking plate 300. The clearance slot is only located in the area of ​​the second latch 500, ensuring that while the second latch 500 passes through, the first latch 400 can contact the frame 100 to achieve locking.

[0062] During the insertion of the card plate 300 into the card slot 101, the first latch 400 and the second latch 500 will undergo elastic deformation due to contact with the skeleton 100. Therefore, a portion of the second latch 500 will be temporarily located on the first side of the card plate 300. At this time, the second clearance groove 103 allows the second latch 501 extending to the first side to pass through, ensuring that the second latch 500 can smoothly pass through the card slot 101 and complete the engagement of the first and second card components.

[0063] In some embodiments, limiting ribs 600 are provided on both the first and second sides of the card plate 300, and the limiting ribs 600 are used to abut against the inner wall of the card slot 101. After the first and second card pieces are connected, the limiting ribs 600 can fill the gap between the card plate 300 and the card slot 101, that is, the limiting members provide support between the card plate 300 and the card slot 101, ensuring that the card plate 300 is located between the card slots 101. This avoids the situation where the card plate 300 is not supported and is too close to one side of the card slot 101, causing the latch on the other side to detach from the support of the frame 100. This improves the stability of the connection.

[0064] In some embodiments, the height direction of the limiting rib 600 is away from the card plate 300; the height of the limiting rib 600 gradually increases from the direction closer to the body 200. The end that is first inserted into the card slot 101 has a smaller size, which can guide the card plate 300 to be smoothly inserted into the card slot 101, reducing assembly resistance. As the card plate 300 is inserted deeper into the card slot 101, the limiting rib 600 can gradually support the card slot 101, which can facilitate installation while ensuring structural stability after installation.

[0065] In some embodiments, the length direction of the limiting rib 600 is the extension direction of the clamping plate 300. There are four limiting ribs 600 in total. There are two limiting ribs 600 on the first side of the clamping plate 300, which are located on both sides of the receiving cavity. There are two limiting ribs 600 on the second side of the clamping plate 300, which are located on both sides of the receiving cavity. Specifically, the positions of the limiting ribs 600 on both sides of the clamping plate 300 correspond to each other.

[0066] In some embodiments, the two ends of the card plate 300 on the side away from the body 200 are chamfered. The chamfered design eliminates the sharp edges of the card plate 300 ends. On the one hand, it can play a preliminary guiding role during assembly, guiding the card plate 300 to quickly align with the inlet of the card slot 101, reducing assembly jamming caused by the obstruction of the sharp edges of the card plate 300 ends, and improving assembly efficiency. On the other hand, it can prevent operators from being scratched by sharp edges during assembly and maintenance, improving operational safety. At the same time, the chamfered structure can reduce the collision and friction between the card plate 300 and the edge of the card slot 101 when the card plate 300 is inserted into the card slot 101, reducing wear on the card plate 300 and the card slot 101.

[0067] Furthermore, this application also provides a vehicle that employs the aforementioned snap-fit ​​structure; the frame 100 is part of a vehicle component; and the body 200 is part of another vehicle component. In a vehicle employing this snap-fit ​​structure, the corresponding two vehicle components can be tightly connected, preventing separation under harsh conditions such as long-term vibration and external impact, thus maintaining a reliable connection.

[0068] It is understandable that the snap-fit ​​structure can be the vehicle body or a component that needs to be installed on the vehicle body. For example, the body 200 is part of the vehicle body and the frame 100 is part of the vehicle component; or, the frame 100 is part of the vehicle body and the body 200 is part of the vehicle component; or, the body 200 is part of the vehicle component and the frame 100 is part of another vehicle component.

[0069] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
