[0038] The following is combined with Figures 1 to 6 This invention describes the bumper trim strip connection structure, bumper assembly, and vehicle according to embodiments of the present invention.

[0039] According to an embodiment of this utility model, in one aspect, a bumper trim strip connection structure is provided, suitable for the installation and connection of trim strips in the front and rear bumper assemblies of a vehicle. Generally, a vehicle has a first direction Z, a second direction X, and a third direction Y that intersect each other. In this embodiment, the first direction Z is the height direction of the vehicle, the second direction X is the front-rear direction of the vehicle, and the third direction Y is the left-right direction of the vehicle. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0040] Specifically, such as Figure 1 As shown, the bumper trim connection structure includes the bumper body 1 and the trim 2. (As indicated...) Figure 3 As shown, the bumper body 1 is provided with a first connecting part 101. (As indicated...) Figure 2 As shown, the decorative strip 2 is provided with a second connecting part 201 that is connected to the first connecting part 101.

[0041] In this configuration, one of the first connecting portion 101 and the second connecting portion 201 is provided with a snap-fit ​​member 3, and the other is provided with a slot 4 that mates with the snap-fit ​​member 3. The snap-fit ​​member 3 snaps into the slot 4. That is, the first connecting portion 101 is provided with a snap-fit ​​member 3, and the second connecting portion 201 is provided with a matching slot 4. Alternatively, the first connecting portion 101 is provided with a slot 4, and the second connecting portion 201 is provided with a matching snap-fit ​​member 3. Furthermore, as... Figure 3 As shown, the first connecting part 101 is also provided with a first limiting rib 5, which is used to limit the decorative strip 2.

[0042] For example, the previous bumper assembly will be used as an example for illustration, see [link to previous text]. Figure 1 and Figure 3 As shown, the bumper body 1 includes an upper bumper body 102 and a lower bumper grille 103, with a first connecting part 101 at the connection between the upper bumper body 102 and the lower bumper grille 103. For ease of installation, the decorative strips 2 are two in number and arranged symmetrically. Figure 2 As shown, the second connecting part 201 is provided with a slot 4. For example... Figure 3 As shown, the first connecting part 101 is provided with a snap-fit ​​member 3 and a first limiting rib 5.

[0043] Specifically, during installation, the snap-fit ​​component 3 snaps into the slot 4, allowing the decorative strip 2 to engage with both the upper bumper body 102 and the lower bumper grille 103, thereby tightening the decorative strip 2 in the X direction to control the surface difference between the decorative strip 2 and the bumper body 1. Simultaneously, by designing a first limiting rib 5, the decorative strip 2 overlaps with the first limiting rib 5, serving a limiting function and controlling the gap between the decorative strip 2 and the bumper body 1. When the gap or surface difference does not meet design requirements, the overall appearance quality of the vehicle can be ensured by adjusting the snap-fit ​​structure and the limiting rib. This allows for localized adjustments to parts to ensure gap and surface difference requirements, simplifying the operation and reducing processing costs.

[0044] This configuration, through the cooperation of the snap-fit ​​part 3 and the snap-fit ​​groove 4, allows the decorative strip 2 to be snapped onto the bumper body 1. At the same time, the decorative strip 2 overlaps with the first limiting rib 5, which provides a limiting and supporting function for the decorative strip 2. This improves the gap and surface difference between the decorative strip 2 and the bumper body 1, thereby improving the connection accuracy between the decorative strip 2 and the bumper body 1, improving the appearance quality of the vehicle, enhancing the aesthetics and refinement of the whole vehicle, and helping to improve product competitiveness.

[0045] Optionally, in some embodiments of this utility model, such as Figure 3 As shown, there are multiple snap-fit ​​pieces 3, which are spaced apart along the extension direction of the decorative strip 2, and the slots 4 are corresponding to the snap-fit ​​pieces 3 one by one. It should be noted that the third direction Y in the figure is the extension direction of the decorative strip 2.

[0046] For example, such as Figure 3 As shown, a plurality of snap-fit ​​pieces 3 are spaced apart on the first connecting portion 101 located on one side of the upper body 102 of the bumper, and a plurality of snap-fit ​​pieces 3 are also spaced apart on the first connecting portion 101 located on one side of the lower grille 103 of the bumper. Figure 2 As shown, the multiple slots 4 on the decorative strip 2 correspond one-to-one with each snap-fit ​​piece 3. In addition, to prevent the edges of the decorative strip 2 from warping, the ends of the decorative strip 2 are also provided with slots 4 for snap-fitting and fixing the ends.

[0047] This design, through multiple interlocking structures spaced apart along the extension direction of the decorative strip 2, ensures a stable connection between the decorative strip 2 and the bumper body 1, and better guarantees the surface difference and uniformity between the decorative strip 2 and the bumper body 1, effectively improving the overall refinement of the vehicle.

[0048] Furthermore, in some embodiments of this utility model, such as Figure 3 As shown, there are multiple first limiting ribs 5, which are spaced apart along the extension direction of the decorative strip 2. This arrangement, with multiple limiting ribs evenly distributed along the extension direction of the decorative strip 2, effectively increases the contact points and limiting points between the decorative strip 2 and the bumper body 1, providing reliable limiting support for the decorative strip 2. This helps maintain a uniform gap between the decorative strip 2 and the bumper body 1, thereby better controlling the gap and its uniformity, and improving the overall aesthetics and assembly quality.

[0049] Specifically, in some embodiments of this utility model, such as Figure 2 As shown, the decorative strip 2 includes a decorative strip body 202, and a second connecting portion 201 protruding from the decorative strip body 202 on the side facing the bumper body 1. Figure 4As shown, the first limiting rib 5 includes a first rib segment 501 and a second rib segment 502, with the second rib segment 502 connected to the first rib segment 501. Figure 6 As shown, the first rib segment 501 is used to limit the second connecting portion 201 in the first direction Z, and the second rib segment 502 is used to limit the decorative strip body 202 in the second direction X. The first direction Z intersects the second direction X. Optionally, as... Figure 3 As shown, the extension length of the first limiting rib 5 at different positions is different, and it can be adaptively adjusted according to the cross-sectional length of the decorative strip 2 so as to better limit the decorative strip 2.

[0050] With this configuration, in the second direction X, the snap-fit ​​mechanism formed by the snap-fit ​​component 3 and the snap-fit ​​groove 4 achieves X-direction tension, and the decorative strip body 202 overlaps with the second rib section 502. The two work together to reliably limit and fix the decorative strip 2 in the X direction, helping to maintain the surface difference between the decorative strip 2 and the bumper body 1. Furthermore, in the first direction Z, the first rib section 501 provides Z-direction support and limitation for the second connecting part 201, effectively ensuring the gap between the decorative strip 2 and the bumper body 1. Thus, the first limiting rib 5 can limit the decorative strip 2 in both the Z and X directions, working in conjunction with the snap-fit ​​structure to ensure a tight fit between the decorative strip 2 and the bumper body 1, thereby improving the overall appearance quality and assembly level of the vehicle.

[0051] Furthermore, in some embodiments of this utility model, such as Figure 6 As shown, the first limiting rib 5 also includes an inclined transition section 503, which is disposed between the first rib section 501 and the second rib section 502. This arrangement guides the decorative strip 2, allowing it to slide and be positioned more easily along a predetermined path during installation, reducing resistance and difficulty, and improving ease of installation. Furthermore, it allows for more flexible position adjustment of the decorative strip 2 during installation, effectively preventing interference and helping to maintain the gap and surface difference between the decorative strip 2 and the bumper body 1, thus improving overall assembly quality.

[0052] Optionally, in some embodiments of this utility model, such as Figure 2 As shown, the second connecting part 201 is provided with a connecting ear 2011, and the connecting ear 2011 is provided with a slot 4. Figure 4 As shown, the snap-fit ​​member 3 is provided with a protrusion 301 extending along the second direction X. The protrusion 301 is used to support the connecting ear 2011 when it is snapped into the snap-fit ​​member 3.

[0053] Specifically, during installation, such as Figure 5As shown, the snap-fit ​​member 3 extends into the snap-fit ​​groove 4 to snap the connecting ear 2011 onto the snap-fit ​​member 3. At this time, the protrusion 301 can provide Z-axis support for the connecting ear 2011. This design facilitates the installation and connection of the decorative strip 2 by providing the connecting ear 2011, and the protrusion 301 provides additional Z-axis support for the connecting ear 2011, which helps prevent deformation of the connecting ear 2011 during installation, ensures stability after connection, and improves the connection strength and durability of the snap-fit ​​member 3.

[0054] Optionally, in some embodiments of this utility model, such as Figure 4 As shown, the bumper trim strip connection structure also includes a pair of second limiting ribs 6, which are respectively disposed on both sides of the snap-fit ​​member 3. The second limiting ribs 6 are used to limit the connecting lug 2011 in the first direction Z. The first direction Z intersects the second direction X. Specifically, as shown... Figure 3 As shown, there are multiple snap-fit ​​pieces 3, and correspondingly, each snap-fit ​​piece 3 has a pair of second limiting ribs 6 on both sides. Figure 5 As shown, during installation, the snap-fit ​​3 extends into the snap-fit ​​slot 4 to snap the connecting ear 2011 onto the snap-fit ​​3, and the connecting ear 2011 overlaps on a pair of second limiting protrusions 6.

[0055] This configuration allows for reliable support and positioning of the connecting ear 2011 via a pair of second limiting ribs 6, ensuring a stable connection between the decorative strip 2 and the bumper body 1. This improves overall stability and reliability, and better controls the gap between the decorative strip 2 and the bumper body 1, helping to maintain the consistency and aesthetics of the vehicle's appearance and enhancing the overall quality of the product.

[0056] Furthermore, in some embodiments of this utility model, such as Figure 4 As shown, the snap-fit ​​component 3 is provided with a first inclined guide portion 302, and a pair of second limiting ribs 6 are provided with second inclined guide portions 601. This arrangement, under the action of the first inclined guide portion 302 and the second inclined guide portion 601, provides a guiding function for the assembly of the connecting ear 2011 with the snap-fit ​​component 3 and the second limiting ribs 6, greatly simplifying the assembly process, reducing adjustment and calibration work during assembly, improving assembly efficiency and convenience, and helping to reduce gaps and surface differences after assembly, maintaining a neat and consistent appearance between the decorative strip 2 and the bumper body 1, thus contributing to improving the overall aesthetics and quality of the vehicle.
