Description

Technical Field

[0001] This utility model relates to the field of automotive rear bumpers, specifically a lightweight support plate for automotive rear bumpers. Background Technology

[0002] The rear bumper bracket support plate is a metal or plastic structural component connecting the rear bumper to the vehicle body. Typically made of high-strength materials, it serves to fix, support, and buffer the impact. Located inside the bumper, it is connected to the vehicle's longitudinal beams or floorboards via bolts or clips. It disperses collision impact forces to protect the vehicle structure while ensuring the bumper's installation accuracy and stability. Some designs also incorporate energy-absorbing crumple zones, which absorb energy through deformation during low-speed collisions, reducing repair costs. Its design must balance lightweight construction with rigidity, while also providing mounting positions for components such as radar and wiring harnesses.

[0003] Existing automotive rear bumper bracket support plates typically employ a one-piece injection-molded structure made of high-strength plastics or composite materials. Their shape and angle are fixed during manufacturing and cannot be adjusted according to actual installation requirements. This design can only adapt to the rear bumper installation position of specific car models, resulting in poor versatility. Different support plate molds are often required for different car models, increasing production costs and development cycles. Furthermore, due to the non-adjustable angle, even slight deviations during assembly can lead to a decrease in the fit between the bumper and the car body, affecting the aesthetic appearance. This makes it difficult to adapt to different car models or modification needs, thus limiting its application scope.

[0004] In summary, to improve the versatility and assembly adaptability of the rear bumper bracket support plate, it is necessary to solve the problems of the existing one-piece structure's non-adjustable angle and limited vehicle model compatibility, so that it can flexibly match the needs of different installation positions, while taking into account structural strength and lightweight characteristics.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] Refer to the instruction manual appendix Figures 1 to 5A lightweight support plate for a car rear bumper includes multiple fixing pieces 1. The rightmost fixing piece 1 is provided with a side positioning mechanism for engaging the end of the rear bumper. Each fixing piece 1 has a snap-fit ​​component at its top for positioning the rear bumper. Each fixing piece 1 also has a fixing component for fixing the fixing piece 1 to the car body. Each fixing piece 1 has two mounting holes 5 at both ends. Multiple spring pieces 6 are provided inside the mounting holes 5. The spring pieces 6 are fixed at an angle and are circumferentially distributed. A stop block 7 is fixed at the end of each spring piece 6. External threads 8 are provided on the outer side of each spring piece 6. Nuts 9 are connected to the outer side of each spring piece 6 through the external threads 8. A clamping groove 10 is provided on the inner side of each spring piece 6. A ball seat 11 is provided on the inner side of the clamping groove 10. A telescopic mechanism is provided between two corresponding ball seats 11 for adjusting the distance between two adjacent fixing pieces 1.

[0025] It should be noted that multiple fixing plates 1 are clamped and positioned with the ball seat 11 of the telescopic mechanism through the circumferentially inclined spring plates 6 in their mounting holes 5. Tightening the nut 9 can compress the spring plates 6, causing the clamping groove 10 of the spring plates 6 to press against the ball seat 11 to generate a radial locking force, effectively fixing the angle of the telescopic mechanism. At the same time, after loosening the nut 9, the restoring force of the spring plates 6 allows the angle of the telescopic mechanism to be smoothly adjusted, realizing stepless adjustment of the angle of adjacent fixing plates 1, and significantly improving the adaptability of the bracket to different vehicle body mounting positions.

[0026] Refer to the instruction manual appendix Figure 1 and Figure 2 The side positioning mechanism includes a connecting component and an mounting component. The connecting component is located at the bottom of the rightmost fixing piece 1, and the mounting component is located on the connecting component. The connecting component is used to fix the mounting component, and the mounting component is used to engage the end of the rear bumper.

[0027] It should be noted that the mounting components are fixedly installed by connecting the components, and the engagement and positioning of the mounting components with the end of the rear bumper ensures the lateral installation accuracy of the bumper.

[0028] Refer to the instruction manual appendix Figure 1 and Figure 2 The connecting assembly includes a connecting plate 21 fixed to the bottom of the rightmost fixing piece 1, a connecting seat 22 disposed on the outside of the connecting plate 21, and a positioning screw 23 connected to the connecting seat 22. The connecting seat 22 is fixedly connected to the connecting plate 21 by the positioning screw 23.

[0029] It should be noted that the mounting components are positioned and installed through the cooperation of the connecting plate 21 and the connecting seat 22, and the positioning screw 23 provides reliable locking.

[0030] Refer to the instruction manual appendix Figure 2The mounting components include a side snap-fit ​​plate 24 fixed to the bottom of the connector 22, a snap-fit ​​groove 25 formed on the side snap-fit ​​plate 24, a weight reduction groove 26 formed on the side snap-fit ​​plate 24, and a fixing hole 27 formed on the side snap-fit ​​plate 24. The end of the rear bumper is snapped and fixed to the snap-fit ​​groove 25 by a snap-fit, and the side snap-fit ​​plate 24 is fixed to the car body by screws.

[0031] It should be noted that the mechanical interlock between the slot 25 and the rear bumper buckle enables quick positioning, the weight reduction slot 26 reduces weight while ensuring structural strength, and the fixing hole 27 provides screw fixing points to enhance stability.

[0032] Refer to the instruction manual appendix Figure 4 The snap-fit ​​assembly includes a fixing plate 31 fixed to the top of the fixing plate 1, a mounting plate 32 fixed to the fixing plate 31, and a card 33 fixed to the mounting plate 32. The card 33 is tilted upwards, and the rear bumper buckle cooperates with the card 33.

[0033] It should be noted that the bumper buckle is guided into the locking position by the upward tilting card 33, and the vertical positioning of the bumper is achieved by using the inclined self-locking principle to prevent it from coming off while driving.

[0034] Refer to the instruction manual appendix Figure 3 and Figure 4 The fixing component includes a positioning hole 41 opened on the fixing plate 1 and a self-tapping screw 42 connected inside the positioning hole 41. The fixing plate 1 is fixedly connected to the car body by the self-tapping screw 42.

[0035] It should be noted that the self-tapping screw 42 penetrates the car body to achieve a single-point strong fixation of the fixing piece 1, and the positioning hole 41 provides a precise alignment function, which significantly improves installation efficiency and reduces assembly difficulty.

[0036] Refer to the instruction manual appendix Figure 4 and Figure 5 The telescopic mechanism includes a guide assembly and a locking assembly. The guide assembly is used to adjust the spacing between adjacent fixed pieces 1, and the locking assembly is used to lock the guide assembly.

[0037] It should be noted that the guide assembly enables stepless adjustment of the spacing between the fixing pieces 1, and the locking assembly provides a staged locking function. Together, they meet the installation size requirements of different vehicle models.

[0038] Refer to the instruction manual appendix Figure 4 and Figure 5 The guide assembly includes a rod 121 fixed on one side ball seat 11, a sleeve 122 fixed on the other side ball seat 11, a positioning groove 123 opened on the rod 121, and a positioning strip fixed inside the sleeve 122. The positioning strip is slidably connected to the positioning groove 123, and the sleeve 122 is slidably connected to the rod 121.

[0039] It should be noted that linear displacement adjustment is achieved through the sliding engagement of the insertion rod 121 and the sleeve 122, and the interlocking structure of the positioning strip and the positioning groove 123 prevents relative rotation and ensures that the alignment is maintained during the extension and retraction process.

[0040] Refer to the instruction manual appendix Figure 4 and Figure 5 The locking assembly includes a ratchet 124 disposed on the outside of the insert 121 and a limiting screw 125 connected to the sleeve 122, the end of the limiting screw 125 having a rounded corner structure.

[0041] It should be noted that the telescopic length is locked by the engagement of the ratchet 124 with the end of the limit screw 125. The rounded end of the limit screw 125 avoids damage to the ratchet 124 and provides a reliable locking mechanism that can be repeatedly adjusted.

[0042] Working principle: During installation, the distance between adjacent fixing pieces 1 is first adjusted by sliding the insert rod 121 and the sleeve 122. The positioning groove 123 of the insert rod 121 slides along the positioning strip inside the sleeve 122 to prevent deflection. During the adjustment, the end of the limit screw 125 engages with the ratchet 124 of the insert rod 121 to complete linear locking. Then, the nut 9 in the mounting hole 5 is loosened, allowing the circumferentially distributed inclined spring pieces 6 to elastically reset, relieving the radial pressure on the ball seats 11 at both ends of the telescopic mechanism. At this time, the ball seats 11 can be freely twisted to adjust the included angle between the fixing pieces 1. After the angle is determined, tighten the nut 9 again. The nut 9 compresses the spring 6 to retract inward. The clamping groove 10 generates a radial locking force on the ball seat 11 to fix the angle. After the spacing and angle are adjusted, the fixing plate 1 is attached to the car body. The self-tapping screw 42 is used to penetrate the positioning hole 41 and lock it to the car body. Finally, the bumper is assembled. The end buckle of the bumper is inserted into the slot 25 of the side snap plate 24 to form a lateral interlock. At the same time, the upper buckle of the bumper slides into the inclined card 33 on the top of the fixing plate 1. The inclined self-locking is used to complete the vertical positioning.
