The car bumper is a safety device that absorbs and reduces external impact and protects the front and rear of the car body. As a core component of the car's appearance, the bumper has a complex curved shape, including arcs, corners, and textures, and the curved parameters of different car models vary significantly.

[0003] Traditional bonding mechanisms typically use rigid tooling or a single suction cup assembly to bond and fix the curved surface of the bumper. This often results in problems such as low bonding accuracy, poor adaptability, and uneven pressure distribution, making it difficult to meet the requirements of welding, testing, and gluing processes for tight bonding of curved surfaces. Utility Model Content

[0004] The purpose of this invention is to provide a bumper surface adaptive fitting mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bumper curved surface adaptive fitting mechanism, including a support plate, a movable adjustment component, and an adaptive fitting component. Fixed blocks are welded to both the front and rear sides of the upper part of the support plate, and a support rod connects the fixed blocks. A movable adjustment component is installed on the outer side of the support rod. An adaptive fitting component is installed on the side of the movable adjustment component closest to the center line of the support plate. The adaptive fitting component includes a first telescopic rod, a movable plate, a spherical shell, a sphere, a connecting rod, a fitting plate, a flexible silicone airbag, and a flexible rubber bonding layer. A movable plate is fixed to the front end of the first telescopic rod, and a spherical shell is fixed to the middle of the movable plate. A sphere is disposed inside the spherical shell, and a connecting rod is fixed to the front side of the sphere. A fitting plate is fixed to the front side of the connecting rod, and a flexible silicone airbag is disposed on the surface of the fitting plate.

The upper side of the movable sleeve is embedded with the threaded cylinder, and the threaded positioning rod is screwed onto the internal thread of the threaded cylinder.

[0007] Furthermore, the movable sleeve is fitted onto the outside of the support rod and slidably connected to the support rod, and the support rod is bolted to the fixing blocks on both sides, and the surface of the support rod is provided with scale values.

[0008] Furthermore, the adaptive bonding component also includes a micro air pump, which is installed on one side of the rear side of the bonding plate, and the micro air pump is connected to the flexible silicone airbag through a pipe embedded in the bonding plate.

[0009] Furthermore, a connecting block is fixed to the upper middle part of the support rod, and a second telescopic rod is installed on the front side of the connecting block, and a fixing sleeve is fixed to the front end of the second telescopic rod.

[0010] Furthermore, a central positioning component is installed on the front side of the fixed sleeve, and the central positioning component includes a threaded connector, which is threadedly screwed into the interior of the front side of the fixed sleeve.

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0018] like Figures 1-2 As shown, the bumper curved surface adaptive fitting mechanism includes a support plate 1, a movable adjustment component 4, and an adaptive fitting component 5. Fixing blocks 2 are welded to the front and rear sides of the upper part of the support plate 1, and a support rod 3 is connected between the fixing blocks 2. The movable adjustment component 4 is installed on the outer side of the support rod 3. The movable adjustment component 4 includes a movable sleeve 401, a threaded cylinder 402, and a threaded positioning rod 403. The threaded cylinder 402 is embedded in the upper side of the movable sleeve 401, and the threaded positioning rod 403 is screwed into the internal thread of the threaded cylinder 402. The movable sleeve 401 is sleeved on the outer side of the support rod 3 and is connected to the support rod 5. The rod 3 is slidably connected, and the support rod 3 is bolted to the fixing blocks 2 on both sides. The surface of the support rod 3 is marked with scale values. The movement of the movable sleeve 401 on the outside of the support rod 3 facilitates the adjustment of the position of the movable sleeve 401 and the adaptive fitting component 5, thereby facilitating the adjustment of the fitting position of the adaptive fitting component 5. It has good applicability. The scale values ​​on the surface of the support rod 3 make it easy to know the positional distance between two adjacent movable sleeves 401. After adjustment, tightening the threaded positioning rod 403 inside the threaded cylinder 402 can lock the movable sleeve 401. It is quite flexible in use.

[0019] like Figures 1-2As shown, an adaptive bonding component 5 is installed on the side of the movable adjustment component 4 near the center line of the support plate 1. The adaptive bonding component 5 includes a first telescopic rod 501, a movable plate 502, a spherical shell 503, a sphere 504, a connecting rod 505, a bonding plate 506, a flexible silicone airbag 507, and a flexible rubber bonding layer 508. The movable plate 502 is fixed to the front end of the first telescopic rod 501, and the spherical shell 503 is fixed to the middle of the movable plate 502. The sphere 504 is disposed inside the spherical shell 503, and the connecting rod 505 is fixed to the front side of the sphere 504. The bonding plate 506 is fixed to the front side of the connecting rod 505, and the flexible silicone airbag 507 is disposed on the surface of the bonding plate 506. The flexible rubber bonding layer 508 is adhered to the surface of the flexible silicone airbag 507. The adaptive bonding component 5 also includes a micro air pump 5. 09. A miniature air pump 509 is installed on one side of the back of the bonding plate 506, and the miniature air pump 509 is connected to the flexible silicone airbag 507 through a pipe embedded in the bonding plate 506. The spherical shell 503 and the sphere 504 form a universal spherical rotary joint structure. Therefore, the sphere 504 in the spherical shell 503 can rotate in multiple directions to adjust the orientation of the connecting rod 505 and the bonding plate 506, so as to adapt to the tilt angle of the bumper surface. The extension and retraction of the first telescopic rod 501 can facilitate the movement of the moving plate 502 and the bonding plate 506, so that the flexible rubber bonding layer 508 is attached to the surface of the bumper. At this time, the miniature air pump 509 can inflate the flexible silicone airbag 507, so that the flexible silicone airbag 507 forms a contoured curved surface that fits with the curved surface of the bumper, thereby avoiding surface damage caused by rigid compression.

[0020] like Figure 1 and Figure 3As shown, a connecting block 6 is fixed to the upper middle part of the support rod 3, and a second telescopic rod 7 is installed on the front side of the connecting block 6. A fixing sleeve 8 is fixed to the front end of the second telescopic rod 7. A middle positioning component 9 is installed on the front side of the fixing sleeve 8. The middle positioning component 9 includes a threaded connector 901, which is threadedly screwed into the front interior of the fixing sleeve 8. The middle positioning component 9 also includes a positioning plate 902 and a shape memory alloy sheet 903. The positioning plate 902 is fixed to the front end of the threaded connector 901, and the shape memory alloy sheet 903 is provided on the front side of the positioning plate 902. The middle positioning component 9 also includes a damping shaft 904, a connecting plate 905, and a negative pressure suction cup 906. The damping shaft 904 is rotatably connected to the upper and lower sides and the left and right sides of the rear side of the positioning plate 902. The other end of the damping shaft 904 is connected to a negative pressure suction cup 906 via a connecting plate 905. The threaded connection between the threaded connector 901 and the fixed sleeve 8 facilitates the disassembly and assembly of the positioning plate 902 and the shape memory alloy sheet 903, allowing for the replacement of shape memory alloy sheets 903 with different curved surfaces. This ensures that the shape memory alloy sheet 903 has a curved surface structure that adapts to the current center of the bumper. The extension and retraction of the second telescopic rod 7 facilitates the movement of the positioning plate 902 and the shape memory alloy sheet 903, enabling the front and rear shape memory alloy sheets 903 to position and clamp the front and rear sides of the bumper above the support plate 1. At the same time, the damping shaft 904 and the connecting plate 905 facilitate the rotation and adjustment of the position of the negative pressure suction cup 906, allowing several negative pressure suction cups 906 to adhere and fix the surface of the bumper, improving the stability of the fit.

[0021] In summary, as Figures 1-3 As shown, the adaptive fitting mechanism for the bumper surface can be used by first adjusting the position of the movable sleeve 401 and the adaptive fitting component 5 by moving the movable sleeve 401 outside the support rod 3, thereby adjusting the fitting position of the adaptive fitting component 5. This provides good applicability. At this time, the surface of the support rod 3 has scale values ​​to make it easy to know the positional distance between two adjacent movable sleeves 401. After adjustment, tightening the threaded positioning rod 403 inside the threaded cylinder 402 can lock the movable sleeve 401. The positioning plate 902 and the memory alloy sheet 903 can also be disassembled and assembled through the threaded connection between the threaded connector 901 and the fixed sleeve 8 to replace the memory alloy sheet 903 with different curved surfaces, so that the memory alloy sheet 903 is a curved surface structure that is adapted to the current bumper center. Next, the bumper is positioned on the upper middle part of the support plate 1. Then, the movement of the positioning plate 902 and the shape memory alloy sheet 903 is driven by the extension and retraction of several second telescopic rods 7. This allows the front and rear shape memory alloy sheets 903 to position and clamp the front and rear sides of the bumper above the support plate 1. At the same time, the position of the negative pressure suction cup 906 is adjusted by rotating the damping shaft 904 and the connecting plate 905, so that the several negative pressure suction cups 906 can adsorb and fix the surface of the bumper, improving the fit stability. Then, the extension and retraction of the first telescopic rod 501 facilitates the movement of the moving plate 50. 2. The movement of the bonding plate 506, and the multi-directional rotation adjustment of the connecting rod 505 and the bonding plate 506 by the ball 504 in the spherical shell 503, adapts to the tilt angle of the bumper surface, so that the flexible rubber bonding layer 508 adheres to the bumper surface. Then, the flexible silicone airbag 507 is inflated by the micro air pump 509, so that several flexible silicone airbags 507 form a contoured curved surface that fits with the bumper surface, thereby avoiding surface damage caused by rigid compression. This completes the use process of the bumper surface adaptive bonding mechanism.
