Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing technology, and more specifically, it relates to a concealed roof limiting assembly structure that is easy to disassemble and assemble. Background Technology

[0002] With the continuous development of automobile manufacturing technology, consumers are increasingly demanding higher aesthetics and practicality from car interiors. Among these, the car headliner, as a crucial component of the interior, directly impacts the user's driving experience and ease of maintenance through the stability of its installation structure and the convenience of its disassembly and assembly.

[0003] Currently, the connection between the car roof and the body is a common fixing method. For example, the patent with announcement number "CN210436056U" discloses a car roof buckle assembly and fixing mechanism. By fixing a pair of spring clips on the buckle assembly base, when the buckle and buckle fixing block are placed on the buckle assembly base, the spring clips will hold the buckle in place. As the rotating arm rotates, there will be no unstable fixing during the assembly process.

[0004] However, in actual use, the above structure still has the following problems: 1. In order to ensure that the buckle is installed firmly, time is spent aligning the buckle precisely with the installation position when installing the buckle, which reduces the efficiency of ceiling installation; 2. The buckle is basically an exposed structure, which reduces the aesthetics of the ceiling and makes it difficult to meet the user's needs for convenience and aesthetics; 3. Some ceiling buckles require a lot of force to install, and both installation and disassembly are relatively difficult. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hidden roof limiting assembly structure that is easy to disassemble and assemble. It is installed by the guiding action of the guide support plate and the elastic deformation function of the snap-fit ​​connector, which reduces the assembly difficulty, makes the body sheet metal installation more convenient, greatly improves the assembly efficiency, and the limiting bracket is not exposed, making it more aesthetically pleasing.

[0006] The aforementioned easy-to-assemble and disassemble concealed ceiling limiting assembly structure includes a ceiling body with an installation groove. The installation groove contains a concealed snap-fit ​​limiting mechanism that is fixedly connected. The concealed snap-fit ​​limiting mechanism includes an installation plate with its bottom fitting into the installation groove. A limiting bracket is fixedly connected to the installation plate. Snap connectors are provided on both sides of the limiting bracket. The upper end of the snap connector is connected to the limiting bracket, and a deformation space is provided between the lower end of the snap connector and the limiting bracket.

[0007] Preferably, the mounting plate has multiple fixing holes, which are evenly distributed around the outer periphery of the limiting bracket.

[0008] Preferably, the mounting plate is bonded and fixed to the mounting groove using PUR hot melt adhesive.

[0009] Preferably, the upper part of the snap-fit ​​connector is provided with a downwardly inclined upper guide slope, the angle between the upper guide slope and the vertical direction being 15°-35°, and the lower part of the snap-fit ​​connector is provided with an upwardly inclined lower guide slope, the angle between the lower guide slope and the vertical direction being 45°-70°.

[0010] Preferably, each of the card connectors is provided with limiting supports on both sides, the upper end face of the limiting support is located below the card connector, and the limiting support is fixedly connected to the limiting bracket.

[0011] Preferably, the upper part of the roof body is provided with a body sheet metal, and a blind hole corresponding to the limiting bracket is opened on the side of the body sheet metal near the roof body.

[0012] Preferably, a snap-fit ​​plate that cooperates with the snap-fit ​​connector and the limiting support is fixedly connected to the body sheet metal.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model sets the hidden snap-fit ​​limiting mechanism between the body sheet metal and the roof body, so that the hidden snap-fit ​​limiting mechanism is not visible inside or outside the vehicle, that is, the limiting bracket is not exposed, which is more aesthetically pleasing.

[0015] 2. The concealed snap-fit ​​limiting mechanism is fixed to the ceiling body by PUR hot melt adhesive. After installation, the pull-out force of the concealed snap-fit ​​limiting mechanism at room temperature is ≥200N, which makes the ceiling installation more secure and stable.

[0016] 3. This utility model reduces assembly difficulty by using the guiding function of the guide support plate and the elastic deformation function of the snap-fit ​​connector, making the installation of the body sheet metal more convenient and greatly improving the assembly efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Example 1:

[0026] like Figures 1 to 5 As shown, the easily detachable and reassembleable concealed roof limiting assembly structure includes a roof body 1, which is a sheet metal structural component. The roof body 1 has a recessed mounting groove 101 formed by stamping, which is recessed towards the interior of the vehicle. The bottom of the mounting groove 101 is preferably a flat structure. A concealed snap-fit ​​limiting mechanism 2 is fixedly connected within the mounting groove 101. Figure 3 and Figure 4 As shown, the concealed snap-fit ​​limiting mechanism 2 includes a mounting plate 201. The bottom of the mounting plate 201 mates with the mounting groove 101 and is also a planar structure, which facilitates better fixation of the mounting plate 201 and the mounting groove 101. A limiting bracket 203 is fixedly connected to the mounting plate 201. During manufacturing, it is preferable that the mounting plate 201 and the limiting bracket 203 are integrally formed. Snap-fit ​​connectors 204 are provided on both sides of the limiting bracket 203. The upper end of the snap-fit ​​connector 204 is connected to the limiting bracket 203, and the bottom of the snap-fit ​​connector 204 is inclined away from the limiting bracket 203. An elastic deformation space is provided between the lower end of the snap-fit ​​connector 204 and the limiting bracket 203. This elastic deformation space allows the snap-fit ​​connector 204 to elastically deform towards the limiting bracket 203 during assembly of the body sheet metal 3, facilitating the installation of the body sheet metal 3. After installation, the snap-fit ​​connector 204 returns to its original position to fix the body sheet metal 3 in place.

[0027] The mounting plate 201 has multiple fixing holes 202, which are evenly distributed around the outer periphery of the limiting bracket 203. These fixing holes 202 enhance the fixing strength of the mounting plate 201. In this embodiment, the mounting plate 201 is adhered to the mounting groove 101 using PUR hot melt adhesive. During adhesion, excess adhesive can remain and solidify within the fixing holes 202, thereby increasing the adhesion area and making the concealed snap-fit ​​limiting mechanism 2 more securely fixed.

[0028] The snap-fit ​​connector 204 has a downwardly inclined upper guide slope 2041 at its upper part, with an angle of 15°-35° between the upper guide slope 2041 and the vertical direction. The snap-fit ​​connector 204 also has an upwardly inclined lower guide slope 2042 at its lower part, with an angle of 45°-70° between the lower guide slope 2042 and the vertical direction. That is, the upward angle of the lower guide slope 2042 is greater than the downward angle of the upper guide slope 2041. During the installation of the body sheet metal 3, the upper guide slope 2041 acts as a deformation guide, making the body sheet metal 3 easier to install. After installation, the lower guide slope 2042 acts as a limit, preventing the body sheet metal 3 from falling off. When the body sheet metal 3 needs to be disassembled, lifting the body sheet metal 3 upwards with force allows the angle of the lower guide slope 2042 to also act as a guide, driving the snap-fit ​​connector 204 towards the limit bracket 203, thus enabling the body sheet metal 3 to be quickly disassembled. Figure 4 and Figure 5 As shown, each snap-fit ​​connector 204 has a limiting support 205 on both sides. The upper end of the limiting support 205 is located below the snap-fit ​​connector 204. The limiting support 205 plays a limiting role and is fixedly connected to the limiting bracket 203. During manufacturing, the limiting support 205 and the limiting bracket 203 are integrally formed.

[0029] Example 2:

[0030] like Figure 5 As shown, the concealed roof limiting assembly structure is easy to assemble and disassemble. The roof body 1 has a body sheet metal 3 on its upper part. A blind hole corresponding to the limiting bracket 203 is opened on the side of the body sheet metal 3 near the roof body 1. The limiting bracket 203 has inclined guide support plates 2031 around its perimeter, facilitating its entry into the blind hole. A snap-fit ​​plate 301, which cooperates with the snap-fit ​​connector 204 and the limiting support 205, is fixedly connected to the body sheet metal 3. Other aspects are the same as in Embodiment 1. The snap-fit ​​plate 301 is also a sheet metal structure. Part of the upper surface of the snap-fit ​​plate 301 engages with the lower guide slope 2042, and the lower surface of the snap-fit ​​plate 301 can engage with the two limiting supports 205. In this case, the concealed snap-fit ​​limiting mechanism 2 is located between the body sheet metal 3 and the roof body 1, making it invisible from both inside and outside the vehicle, resulting in a more aesthetically pleasing appearance. Furthermore, the concealed snap-fit ​​limiting mechanism 2 has a room temperature pull-out force of ≥200N, which makes the ceiling installation more secure and stable.

[0031] During installation, the body sheet metal 3 is placed on top of the roof body 1 and the hidden snap-fit ​​limiting mechanism 2, so that the top of the limiting bracket 203 is aligned with the blind hole on the body sheet metal 3. Precise positioning is not required at this time. The body sheet metal 3 is placed downwards, and under the guidance of the guide support plate 2031 around the limiting bracket 203, the limiting bracket 203 can quickly enter the blind hole. During the assembly process, the upper guide slope 2041 contacts the blind hole, and the snap-fit ​​connector 204 moves towards the limiting bracket 203 along the upper guide slope 2041, thereby deforming and allowing the snap-fit ​​connector 204 to smoothly enter the blind hole and reset, fixing the blind hole and completing the assembly of the body sheet metal 3.

[0032] This utility model greatly improves assembly efficiency and reduces assembly difficulty through the guiding function of the guide support plate 2031 and the elastic deformation function of the snap-fit ​​connector 204, making the installation of the body sheet metal 3 more convenient, the installation of the roof body 1 more secure and stable, and the limit bracket 203 is not exposed, making it more aesthetically pleasing.

[0033] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
