Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive trim fixing technology, specifically a fixing and installation structure for a front bumper trim strip. Background Technology
[0002] Currently, most common front bumper trim strips are fixed to the front bumper using either a snap-on or adhesive structure. While the snap-on structure offers some ease of installation, its connection strength is limited, and it is prone to loosening or even falling off, especially during long-term use, due to vibrations and bumps from vehicle driving. On the other hand, while the adhesive structure provides a secure connection, it is difficult to disassemble, making it inconvenient for later maintenance and replacement. Utility Model Content
[0003] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a fixed installation structure for the front bumper trim strip.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed installation structure for a front bumper trim strip, comprising a trim strip, wherein a liner strip is provided inside the trim strip, the trim strip and the liner strip are detachably connected along the length direction, a cylindrical insert is provided on the inner wall of the trim strip, the shape of the cylindrical insert is adapted to the front bumper slot, at least two first locking blocks are provided on the inner side of the trim strip, and at least two second locking blocks are provided on the inner side of the liner strip, wherein the first locking blocks and the second locking blocks respectively form a locking engagement with the slots of the front bumper.
[0006] Preferably, the liner has a clearance hole perpendicular to the axis of the cylindrical connector, and the size and position of the clearance hole match the cylindrical connector.
[0007] Preferably, the decorative strip has an edge trim strip at its end, which is fixedly connected to the end face of the decorative strip by bending, and the cross-sectional shape of the edge trim strip is adapted to the contour of the front bumper end.
[0008] Preferably, the cylindrical connector includes a sleeve fixedly connected to the decorative strip, and the sleeve has a slidable movable rod inside, which is fixedly connected to the sleeve by a spring.
[0009] Preferably, a protruding ring is fixedly provided on the outer wall of the end of the movable rod near the spring.
[0010] Preferably, the side of the lining strip closest to the decorative strip is also provided with a reinforcing rib, which is integrally formed with the lining strip.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. The present invention relates to a fixed installation structure for a front bumper trim strip. By inserting a cylindrical plug into a front bumper slot, axial positioning is achieved. The first and second locking blocks respectively enter the slot to form a shearing locking force. The combination of plug and locking connection effectively improves the overall connection strength and prevents the trim strip from loosening or falling off due to vibration or impact during vehicle operation.
[0013] 2. The present invention provides a fixed installation structure for a front bumper decorative strip. The spring buffering effect of the plug-in can effectively absorb external impact energy, improve the vibration resistance of the decorative strip structure, and extend its service life.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 This embodiment provides the following technical solution:
[0021] A fixed installation structure for a front bumper trim strip includes a trim strip 1, with a backing strip 2 inside the trim strip 1. The trim strip 1 and the backing strip 2 are detachably connected along the length direction. The inner wall of the trim strip 1 is provided with a cylindrical plug 3, the shape of which is adapted to the front bumper slot. The inner side of the trim strip 1 is provided with at least two first locking blocks 5, and the inner side of the backing strip 2 is provided with at least two second locking blocks 4. The first locking blocks 5 and the second locking blocks 4 respectively engage with the slots of the front bumper.
[0022] Specifically, the trim strip 1 is pushed along the front bumper, and the cylindrical connector 3 is inserted into the bumper slot for initial positioning. The first locking block 5 and the second locking block 4 then enter the slots in sequence to complete the locking. The first locking block 5 and the second locking block 4 respectively enter the slots on the front bumper, forming a locking force in the shearing direction. This multi-point cooperation ensures that the trim strip 1 is not easy to loosen or fall off during vehicle operation, and can effectively resist the risk of disengagement caused by bumps and vibrations. The trim strip 1 uses a combination of plug-in and locking methods, making the installation process simple and requiring no additional tools.
[0023] The liner 2 is provided with a clearance hole 6 perpendicular to the axis of the cylindrical connector 3, and the size and position of the clearance hole 6 match the cylindrical connector 3. The function of the clearance hole 6 is to provide space for the connector to pass through, so that it can be smoothly inserted into the front bumper slot and avoid structural interference during the assembly process.
[0024] The decorative strip 1 has an edge trim strip 7 at its end. The edge trim strip 7 is fixedly connected to the end face of the decorative strip 1 by bending. The cross-sectional shape of the edge trim strip 7 is adapted to the contour of the front bumper end. The edge trim strip 7 is located at the end of the decorative strip 1 and plays a role in lining and sealing. It can cover the cut or assembly gap at the end of the decorative strip 1, making the front bumper area of the whole vehicle look cleaner and more beautiful.
[0025] The cylindrical connector 3 includes a sleeve 301 fixedly connected to the trim strip 1. The sleeve 301 has a slidable movable rod 302 inside. The movable rod 302 is fixedly connected to the sleeve 301 by a spring 304. A protruding ring 303 is fixedly provided on the outer wall of the end of the movable rod 302 near the spring 304. The protruding ring 303 forms a limiting fit with the inner wall of the sleeve 301 to prevent the movable rod 302 from coming out of the sleeve 301. During vehicle operation, the front bumper area may be subjected to external impacts or vibrations. The elastic connector structure can absorb some energy through the spring 304, reducing the direct impact force on the trim strip 1 and the snap-fit structure, and extending the service life.
[0026] The side of the lining strip 2 closest to the decorative strip 1 is also provided with a reinforcing rib. The reinforcing rib is integrally formed with the lining strip 2. The function of the reinforcing rib is to improve the structural rigidity of the lining strip 2 and the load-bearing capacity of the locking block, which helps to prevent deformation or breakage caused by uneven stress during long-term use.
[0027] In summary, this utility model achieves a stable and reliable connection between the decorative strip 1 and the front bumper through a combination of plug-in components and locking blocks. The flexible plug-in component enhances assembly adaptability and vibration resistance; the liner 2 and its reinforcing ribs improve overall load-bearing capacity; the clearance hole 6 ensures smooth insertion; and the edge-sealing strip 7 combines aesthetics with sealing functionality. The entire structure is rationally laid out, easy to assemble, and convenient to maintain, suitable for the installation needs of the front bumper decorative strip 1 in various vehicle models.
