[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0034] In this disclosure, unless otherwise stated, the directional terms "first direction" and "second direction" refer to two intersecting directions. Specifically, the first direction and the second direction can be perpendicular to each other, as detailed in the following references. Figure 1 As shown.

[0035] The directional terms used, such as "inner" and "outer", refer to the inner and outer parts of the specific structural outline. The terms used, such as "first" and "second", are only used to distinguish one element from another and do not have any order or importance. In addition, "multiple" in this application refers to two or more and includes two.

[0036] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0037] Reference Figures 1 to 3As shown, this disclosure provides a snap-fit ​​structure, which includes a mounting base 1 and an elastic snap-fit ​​member 2. One of the mounting base 1 and the elastic snap-fit ​​member 2 has a snap-fit ​​groove 11, and the other has an elastic snap-fit ​​portion 21. The elastic snap-fit ​​portion 21 is used to snap into the snap-fit ​​groove 11. At least one first snap-fit ​​barb 111 is formed on the inner side of the snap-fit ​​groove 11, and at least one second snap-fit ​​barb 211 is formed on the outer side of the elastic snap-fit ​​portion 21. The first snap-fit ​​barb 111 is used to engage with the second snap-fit ​​barb 211 to prevent the elastic snap-fit ​​portion 21 from disengaging from the snap-fit ​​groove 11.

[0038] In the above technical solution, firstly, through the engaging engagement of the first snap-fit ​​barb 111 and the second snap-fit ​​barb 211, when the elastic snap-fit ​​part 21 is inserted into the snap-fit ​​groove 11, the first snap-fit ​​barb 111 can form a snap-fit ​​engagement with the second snap-fit ​​barb 211, preventing the elastic snap-fit ​​part 21 from easily disengaging from the snap-fit ​​groove 11, thus improving the firmness and stability of the snap-fit. Secondly, the design of the snap-fit ​​groove 11 and the elastic snap-fit ​​part 21 allows users to easily assemble the two parts together. Simply ensure that the elastic snap-fit ​​part 21 is aligned with the snap-fit ​​groove 11 and apply appropriate pressure to the engagement of the first snap-fit ​​barb 111 and the second snap-fit ​​barb 211 to complete the assembly. No additional tools or fasteners are required, simplifying the assembly process. In addition, the elastic snap-fit ​​2 can undergo elastic deformation. When disassembly is required, a certain force is applied outward to cause the second snap-fit ​​barb 211 to undergo elastic deformation and disengage from the first snap-fit ​​barb 111, thereby pulling the elastic snap-fit ​​part 21 out of the snap-fit ​​groove 11. This realizes the disassembly between the elastic snap-fit ​​2 and the mounting base 1, which is convenient for users to operate and is not easily damaged.

[0039] In specific application scenarios, the above-mentioned snap-fit ​​structure can be applied to rooftop tent components. The mounting base 1 of the snap-fit ​​structure can be connected to the top of the vehicle body, and the elastic snap-fit ​​part 2 can be connected to the tarpaulin 100, making it easy to install the tarpaulin 100 on the top of the vehicle body, and facilitating installation and disassembly.

[0040] Optionally, the mounting base 1 can be constructed as an aluminum profile, and the elastic snap-fit ​​2 can be made of rubber. However, this disclosure does not limit the specific materials of the mounting base 1 and the elastic snap-fit ​​2.

[0041] Optionally, refer to Figures 1 to 3As shown, the snap-fit ​​groove 11 is recessed in the mounting base 1 in the first direction A, and the snap-fit ​​groove 11 includes two first inner surfaces 110 that are arranged opposite to each other and spaced apart in the second direction B. At least one of the two first inner surfaces 110 is formed with at least one first snap-fit ​​barb 111. The elastic snap-fit ​​portion 21 extends in the first direction A, and the elastic snap-fit ​​portion 21 includes two first outer surfaces 210 that are arranged opposite to each other in the second direction B. At least one of the two first outer surfaces 210 is formed with at least one second snap-fit ​​barb 211. The first direction A and the second direction B are intersecting.

[0042] In this embodiment, a first snap-fit ​​barb 111 on a first inner surface 110 may engage with a second snap-fit ​​barb 211 on a first outer surface 210. Alternatively, both first inner surfaces 110 may have first snap-fit ​​barbs 111, and both first outer surfaces 210 may have second snap-fit ​​barbs 211. This disclosure does not limit the specific embodiment. The engagement between the first snap-fit ​​barb 111 and the second snap-fit ​​barb 211 effectively prevents the elastic snap-fit ​​part 21 from accidentally dislodging from the snap-fit ​​groove 11, especially when subjected to external vibration or impact.

[0043] In one embodiment, at least two first snap-fit ​​barbs 111 may be provided. Each of the at least two first snap-fit ​​barbs 111 includes at least one first barb group 112, which includes two first snap-fit ​​barbs 111. The two first snap-fit ​​barbs 111 are respectively formed on two first inner surfaces 110 and are positioned opposite each other and spaced apart in the second direction B. At least two second snap-fit ​​barbs 211 may be provided. Each of the at least two second snap-fit ​​barbs 211 includes at least one second barb group 212, which includes two second snap-fit ​​barbs 211. The two second snap-fit ​​barbs 211 are respectively formed on two first outer surfaces 210 and are positioned opposite each other in the second direction B. The first barb group 112 and the second barb group 212 are configured in a one-to-one correspondence.

[0044] In this embodiment, each first barb group 112 includes two first snap-fit ​​barbs 111, located on two opposite first inner surfaces 110; each second barb group 212 also includes two second snap-fit ​​barbs 211, located on two opposite first outer surfaces 210. This design ensures multiple contact points in the second direction B, resulting in a more stable engagement. The one-to-one correspondence of the multiple barb groups makes the fit between the elastic snap-fit ​​portion 21 and the snap-fit ​​groove 11 tighter, greatly reducing the possibility of accidental disengagement.

[0045] Optionally, at least two first barb groups 112 are provided, and the at least two first barb groups 112 are arranged at intervals in the first direction A. At least two second barb groups 212 are provided, and the at least two second barb groups 212 are arranged at intervals in the first direction A.

[0046] In this embodiment, each first barb group 112 and the corresponding second barb group 212 not only provide bidirectional locking in the second direction B, but also form a multi-level locking mechanism through their spaced arrangement in the first direction A. This means that the elastic snap-fit ​​part 21 needs to overcome resistance at multiple stages to disengage from the snap-fit ​​groove 11, greatly improving the snap-fit's firmness.

[0047] In some embodiments, refer to Figures 1 to 3 As shown, the snap-fit ​​groove 11 includes a plurality of snap-fit ​​segments 113 connected sequentially in the first direction A. The snap-fit ​​segments 113 are tapered in the direction away from the opening of the snap-fit ​​groove 11 along the first direction A. The connection between two adjacent snap-fit ​​segments 113 defines a first snap-fit ​​barb 111. The elastic snap-fit ​​member 2 includes an elastic base 22 and an elastic snap-fit ​​portion 21. The elastic snap-fit ​​portion 21 is protruding from the elastic base 22 along the first direction A, and includes snap-fit ​​segments 213 connected sequentially in the first direction A. The snap-fit ​​segments 213 are tapered in the direction away from the elastic base 22 along the first direction A. A second snap-fit ​​barb 211 is formed at the connection between two adjacent snap-fit ​​segments 213.

[0048] That is, the tapering design of the slot section 113 and the snap-fit ​​section 213 along the first direction A allows the elastic snap-fit ​​part 21 to gradually engage during the insertion of each slot section 113 until it is fully embedded in the snap-fit ​​groove 11. The first snap-fit ​​barb 111 between each adjacent slot section 113 and the second snap-fit ​​barb 211 between adjacent snap-fit ​​sections 213 cooperate with each other to form a multi-stage, multi-point locking mechanism. This not only increases the stability after assembly but also effectively prevents the elastic snap-fit ​​part 21 from accidentally coming out of the snap-fit ​​groove 11.

[0049] Secondly, the tapered slot section 113 and the snap-fit ​​section 213 provide excellent guidance, allowing the elastic snap-fit ​​part 21 to be inserted more smoothly into the snap-fit ​​groove 11. The user only needs to align the elastic snap-fit ​​part 21 with the opening of the snap-fit ​​groove 11 and apply appropriate pressure to ensure the correct insertion path, reducing assembly difficulty.

[0050] Furthermore, each time the snap-fit ​​segment 213 passes through a snap-fit ​​segment 113, a distinct "click" sound is produced. This segmented feedback not only helps users confirm whether each segment is correctly engaged, but also provides intuitive operation guidance to ensure the accuracy of assembly.

[0051] Furthermore, when disassembly is required, separation can be achieved step by step by overcoming the resistance between each pair of slot sections 113 and snap-fit ​​sections 213. This method not only reduces the risk of applying excessive force at once, but also allows for non-destructive disassembly, facilitating subsequent maintenance or replacement.

[0052] Reference Figure 1 As shown, the elastic snap-fit ​​component 2 includes an elastic base 22, an elastic snap-fit ​​portion 21, and an elastic lip 23. The elastic snap-fit ​​portion 21 is protruding from the elastic base 22 along the first direction A, and the elastic lip 23 is respectively disposed on both sides of the elastic base 22 along the second direction B, and the elastic lip 23 is used to overlap the mounting base 1.

[0053] In this embodiment, the elastic snap-fit ​​portion 21 engages with the snap-fit ​​groove 11 of the mounting base 1 to form a stable locking structure; while the elastic lips 23 are respectively disposed on both sides of the elastic base 22 along the second direction B and are used to overlap the mounting base 1. This design increases the number of contact points, ensuring stable engagement in multiple dimensions, thereby greatly improving the strength and stability of the connection.

[0054] Furthermore, the elastic lip 23 provides additional support in the second direction B, preventing the elastic snap-fit ​​2 from detaching from the mounting base 1 when subjected to lateral forces. This is especially important when encountering external vibrations or impacts, effectively improving the overall structural safety.

[0055] In addition, the tight overlap between the elastic lip 23 and the mounting base 1 can provide a certain sealing effect, preventing external substances such as dust and moisture from entering the interior and protecting the internal components from contamination or damage.

[0056] In another embodiment, refer to Figure 1 As shown, the mounting base 1 includes a first base portion 10, a second base portion 12, and a third base portion 13; the second base portion 12 and the third base portion 13 are protruding from the first base portion 10 in a first direction A, and are spaced apart and opposite to each other in a second direction B to define a snap-fit ​​groove 11; the elastic lip 23 overlaps the end of the second base portion 12 and the third base portion 13 away from the first base portion 10.

[0057] The overlapping design of the elastic lip 23 with the second base portion 12 and the third base portion 13 provides additional support in the second direction B, effectively preventing the elastic snap-fit ​​member 2 from detaching from the mounting base 1 when subjected to lateral force. Especially when encountering external vibration or impact, this design can significantly improve the safety and stability of the overall structure, but this disclosure does not limit the specific structure of the mounting base 1.

[0058] This disclosure also provides a rooftop tent assembly, which includes a tent fabric 100 and the aforementioned snap-fit ​​structure, wherein the tent fabric is connected to an elastic snap-fit ​​member 2, and a mounting base 1 is used for mounting on the top of the vehicle body.

[0059] In the above technical solution, by setting the above-mentioned snap-fit ​​structure, the tarpaulin 100 can be conveniently and efficiently installed on the top of the vehicle body, and it is easy to install and remove.

[0060] Optionally, the rooftop tent assembly also includes adhesive 200 and fasteners (not shown), with the mounting base 1 for bonding to the top of the vehicle body via adhesive 200 and for securing to the top of the vehicle body via fasteners.

[0061] The aforementioned tarpaulin 100 can be sewn onto the elastic snap fastener 2, and the aforementioned fastener can be constructed as a fastening bolt. The mounting base 1 can be provided with corresponding mounting holes. After the mounting base 1 is bonded to the top of the vehicle body with adhesive 200, it is further fastened to the top of the vehicle body with fastening bolts to improve the stability of the installation.

[0062] This disclosure also provides a vehicle that includes the above-described snap-fit ​​structure, or a vehicle that includes the above-described roof tent assembly.

[0063] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of this disclosure. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
