Description

Technical Field

[0001] This utility model belongs to the field of automotive body structure technology and relates to a sliding bracket mounting structure. Background Technology

[0002] In traditional car design, the front bumper and fender are primarily connected via side-mounted fittings, and the hood and fender are typically separated by headlights. However, with the development of new styling trends, the headlights have been moved down to the center of the bumper, requiring the front bumper to wrap around the hood and fenders, while the fenders also need to extend to the front of the car to match the bumper and hood. This design change brings new assembly challenges: if the traditional side-mounted bracket structure is used, the front bumper is prone to interference with the body or headlights by 15-20mm when installed directly in front, making installation difficult.

[0003] Chinese patent CN206633953U discloses a connection structure between a bumper and a fender. This structure replaces the traditional method where the bumper skin's flange is positioned between the fender flange and the bumper bracket by placing the bumper skin's flange on the lower side of the horizontal mounting bracket of the bumper fixing bracket. This increases the number of clamping points between the fender and the fender bracket, reduces the gap between the bumper fixing bracket and the fender flange, reduces the space required for installation of the bumper skin and the bumper fixing bracket, and results in a more compact structure. It also increases the number of engagement or positioning points between the bumper fixing bracket and the fender. However, in actual assembly, due to the numerous assembly points and complex structure, there is a significant workload involved. Furthermore, under the aforementioned new design, the bumper skin in this connection structure may become stuck in the mold after injection molding, making it unsuitable for the evolving design trends. Utility Model Content

[0004] The purpose of this utility model is to provide a sliding bracket mounting structure for installing the front bumper in the fender area, which solves the problem of interference and mismatch between the front bumper and fender in the engine hood-headlight-fender structure caused by the headlights being moved down to the middle area of ​​the front bumper. It also has the advantages of simple structure and easy assembly.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A sliding bracket mounting structure is used to assemble the front bumper skin flange and the fender flange onto both sides of a primary bracket, including a skin connecting assembly, a sliding bracket, and a primary bracket connecting assembly.

[0007] The skin connection assembly includes multiple skin through holes arranged laterally on the skin flange, and a locking member provided on the skin flange; the sliding bracket includes multiple slots corresponding to the skin through holes, a tongue provided laterally in the slots, and a locking engagement member adapted to the locking member; the primary bracket connection assembly includes fasteners for connecting the primary bracket and the fender flange, and multiple locking plates provided on the primary bracket and corresponding to the slots. The locking plates bend and extend towards the bottom side of the primary bracket so that when the sliding bracket slides laterally, the locking plates pass through the skin through holes and press against the bottom side of the tongue, and the primary bracket carries the fender flange to clamp the skin flange between the primary bracket and the sliding bracket.

[0008] Located at the front of the vehicle body, in the area where the fender and front bumper are matched, this embodiment first fixes the sliding bracket and the skin flange by engaging the engaging parts on the sliding bracket and the skin flange; then, it fixes the primary bracket and the fender flange by fasteners; then, it fits the primary bracket and the sliding bracket together, so that the skin flange is located between the primary bracket and the sliding bracket, the retaining plate passes through the skin through hole longitudinally and extends into the slot on the sliding bracket, and the sliding bracket is slid laterally to move the retaining plate to the bottom side of the tongue and press it against the tongue, thereby fixing the primary bracket and the sliding bracket, locking the front bumper and the primary bracket together, and ensuring the matching requirements of the appearance gap surface difference.

[0009] In some specific implementations, the front end of the card plate is bent downwards and tilted to facilitate insertion into the bottom side of the tongue.

[0010] In some specific embodiments, the engaging component includes an opening extending through the skin flange and an engaging plate laterally disposed within the opening; the engaging component is a bent plate, used to pass through the opening from the bottom side and press against the engaging plate from the top side. The bent plate is S-shaped and includes a front end, a bent section, and a rear end in sequence. The rear end abuts against the outer edge of the opening from the bottom side, the bent section passes through the opening, and the front end presses against the engaging plate from the top side to complete the engagement with the engaging component.

[0011] In some specific embodiments, a notch is provided near the end of the inner edge of the opening. A lever plate is provided in the notch, which is directed to the locking plate and can be moved longitudinally to make room. The notch is used as an insertion port for the bent locking plate. When the bent locking plate is inserted, the lever plate is moved longitudinally to make room. Then the bent locking plate moves laterally into the locking assembly position and engages with the locking plate. At this time, the lever plate can block the bent locking plate laterally to prevent it from sliding out of the notch, thus ensuring the assembly stability of the skin flange and the sliding bracket.

[0012] In some specific embodiments, multiple engaging components are arranged side by side on the skin flange, and multiple engaging components are correspondingly provided on the sliding bracket.

[0013] In some specific embodiments, one side edge of the sliding bracket is provided with a locking element, and the other side edge is provided with an inwardly bent locking groove, and the edge of the skin flange is engaged in the locking groove.

[0014] In some specific embodiments, the fender flange is provided with mounting through holes, the primary bracket is provided with assembly through holes, and the fasteners include bolts and nuts. The fender flange and the primary bracket are connected by bolts passing through the mounting through holes and assembly through holes, and nuts screwed onto the bolts. In other embodiments, they can also be connected and fixed by any conventional method such as screws.

[0015] In some specific implementations, along the lateral sliding direction, one end of the sliding bracket is provided with a limiting plate, and one end of the primary bracket is provided with a corresponding limiting mating plate. The limiting plate can abut against the limiting mating plate to serve as a positioning structure between the sliding bracket and the primary bracket, ensuring that the insertion depth of the card plate and the tongue remains consistent during multiple batches of assembly.

[0016] In some preferred embodiments, the limiting plate is bent at an angle toward the other end of the sliding bracket, and the limiting mating plate abuts against the limiting plate at an angle from the inside, so that the sliding bracket and the primary bracket can be brought closer together by the inclined surface during sliding.

[0017] In some preferred embodiments, the limiting plate and the limiting mating plate are connected by screws, while in other embodiments they can be connected and fixed by any conventional method such as bolts.

[0018] In some preferred embodiments, the screw nut abuts against the limiting plate, and a spring is sleeved on the screw. The spring abuts against the limiting mating plate to cooperate with the screw to clamp and fix the limiting plate and the limiting mating plate. The spring is used to provide support from the back side to cooperate with the screw to clamp and fix the limiting plate and the limiting mating plate, thereby improving the assembly stability between the sliding bracket and the first-level bracket.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention uses a snap-fit ​​mechanism between a snap-fit ​​component on the sliding bracket and a snap-fit ​​component on the fender to fix the sliding bracket and the fender together. Then, fasteners are used to fix the primary bracket and the fender together. After that, the primary bracket and the sliding bracket are fitted together so that the fender is located between the primary bracket and the sliding bracket. The snap-fit ​​plate passes through the through hole of the fender longitudinally and extends into the slot on the sliding bracket. The sliding bracket is slid laterally so that the snap-fit ​​plate moves to the bottom side of the tongue and presses against the tongue, thereby locking the front bumper and the primary bracket together. This solves the interference problem between the front bumper and the fender, allows for effective assembly of the two, and ensures the matching requirements of the appearance gap surface difference.

[0021] The sliding bracket installation method of this utility model can ensure the matching requirements of the gap surface difference between the bumper and the fender at the front of the vehicle. It has a simple, stable, reliable, and space-saving structure and is easy to install. Attached Figure Description

[0039] Example:

[0040] like Figure 1 The sliding bracket mounting structure shown is used to assemble the front bumper skin flange 1 and the fender flange 2 onto both sides of the primary bracket 4, and includes a skin connecting assembly, a sliding bracket 5 and a primary bracket connecting assembly.

[0041] like Figure 2 As shown, the skin connection assembly includes multiple skin through holes 6 arranged laterally on the skin flange 1, and a snap-fit ​​component 7 provided on the skin flange 1; as Figure 5 As shown, the sliding bracket 5 includes multiple slots 501 corresponding to the skin through holes 6, tongues 502 transversely disposed within the slots 501, and engaging parts 503 adapted to the engaging parts 7; as Figure 4 As shown, the primary bracket connection assembly includes fasteners 3 for connecting the primary bracket 4 and the fender flange 2, and multiple clamping plates 8 disposed on the primary bracket 4 and corresponding to the slot 501, the clamping plates 8 being bent and extended toward the bottom side of the primary bracket 4.

[0042] like Figure 10 , Figure 11As shown, when the sliding bracket 5 slides laterally, the clamping plate 8 passes through the skin through hole 6 and presses against the bottom side of the tongue piece 502, and the first-level bracket 4 carries the fender flange 2 to clamp the skin flange 1 between the first-level bracket 4 and the sliding bracket 5.

[0043] Located at the front of the vehicle body, in the area where the fender and front bumper are matched, this embodiment first fixes the sliding bracket 5 and the skin flange 1 by engaging the engaging part 7 on the sliding bracket 5 and the engaging part 503 on the skin flange 1; then fixes the primary bracket 4 and the fender flange 2 by fastener 3; then fits the primary bracket 4 and the sliding bracket 5 together, so that the skin flange 1 is located between the primary bracket 4 and the sliding bracket 5, the locking plate 8 passes through the skin through hole 6 longitudinally and extends into the slot 501 on the sliding bracket 5, and the sliding bracket 5 is slid laterally to move the locking plate 8 to the bottom side of the tongue 502 and presses it against the tongue 502, thereby fixing the primary bracket 4 and the sliding bracket 5, locking the front bumper and the primary bracket together, and ensuring the matching requirements of the appearance gap surface difference.

[0044] In some specific implementation methods, such as Figure 12 As shown, the fender flange 2 has a double-layer structure.

[0045] In some specific implementations, the front end of the card plate 8 is bent downwards and tilted to facilitate insertion into the bottom side of the tongue plate 502.

[0052] In some preferred embodiments, such as Figure 9 As shown, the limiting plate 505 is bent at an incline toward the other end of the sliding bracket 5, and the limiting mating plate 10 is inclined to abut against the limiting plate 505 from the inside, so that the sliding bracket and the first-level bracket can be brought closer to each other by using the inclined surface during sliding.

[0053] In some preferred embodiments, the limiting plate 505 and the limiting mating plate 10 are connected by screws 11. In other embodiments, they can also be connected and fixed by any conventional method such as bolts.

[0054] In some preferred embodiments, the nut of the screw 11 abuts against the limiting plate 505, and a spring 12 is sleeved on the screw 11.
