Description

Technical Field

[0001] This invention relates to the field of automotive sheet metal repair, and in particular to a device for repairing dents on automotive sheet metal surfaces. Background Technology

[0002] A car dent is a localized indentation or deformation of a metal or plastic body part caused by a collision, squeezing, or external impact. Repairing car body dents requires selecting an appropriate method based on the size, location, material, and extent of the damage. Among these methods, the non-marking body repair technique is currently the most mainstream and widely used. During the procedure, hot melt adhesive is heated and melted, then applied to the suction cup of a puller. It is quickly applied to the center of the dent, and after the adhesive has completely cooled and cured, the puller handle is pulled at a steady speed to lift the dent back into its original position.

[0003] However, this repair method relies solely on a single puller suction cup, making it unsuitable for irregularly shaped or complexly designed car dents. Furthermore, it can only repair single-point dents, failing to cover large areas or complex-shaped dents, resulting in poor repair outcomes. Additionally, single-point lifting can lead to concentrated stress at the dent site, causing secondary damage to the vehicle body.

[0004] Therefore, the present invention proposes a device for repairing dents on automotive sheet metal surfaces. Summary of the Invention

[0005] This invention provides a device for repairing dents on automotive sheet metal surfaces, which can solve the problems of existing technologies that rely solely on a single puller suction cup, making it unable to adapt to irregular and complex-shaped automotive dents, and only able to repair single-point dents, making it difficult to cover large areas or complex-shaped dent areas, resulting in poor repair effects.

[0006] A device for repairing dents on automotive sheet metal surfaces, comprising: The system includes a frame, a dent repair assembly, and an angle adjustment assembly. The dent repair assembly is located on one side of the frame and includes a suction cup (first type). Multiple connecting plates are arranged around the suction cup (first type). Each connecting plate has a second suction cup. All connecting plates can rotate around the suction cup (first type). By adjusting the positional relationship between the connecting plates and the suction cup (first type), the suction cups can be adapted to the shape of the dent. The dent can be repaired by pulling the suction cups away from the car's surface. The angle adjustment assembly is located between the frame and the dent repair assembly and is used to adjust the rotation angle of the dent repair assembly.

[0007] Preferably, the angle adjustment assembly includes a telescopic mechanism and a slide rail disposed on the side wall of the frame; the telescopic end of the telescopic mechanism is connected to a rack; the rack is slidably connected to the slide rail; the side wall of the frame is also provided with a support; the side wall of the support is rotatably connected to a gear via a rotating shaft; the gear is meshed with the rack.

[0008] Preferably, the dent repair component includes a mounting bracket; the mounting bracket is fixedly connected to a rotating shaft; the side wall of the mounting bracket is provided with a telescopic mechanism two; the telescopic end of the telescopic mechanism two is connected to a connecting plate; a support rod is provided on the side of the connecting plate away from the telescopic mechanism two; a pressure block is fixedly provided on the other end of the support rod.

[0009] Preferably, the side wall of the mounting bracket is also provided with a drive mechanism; the drive end of the drive mechanism is connected to a lead screw; a limiting pad is fixedly provided at the end of the lead screw away from the mounting bracket; a collar is threadedly connected to the lead screw; a suction cup is fixedly provided on the collar.

[0010] Preferably, a sliding frame is fixedly provided on the side wall of the collar; the sliding frame is a telescopic structure; the other end of the sliding frame is slidably connected to the support rod; the side wall of the connecting plate is provided with a telescopic mechanism three; the telescopic end of the telescopic mechanism three is connected to the support rod; the side wall of the connecting plate is also provided with a sliding groove; the support rod is slidably connected in the sliding groove.

[0011] Preferably, a connecting ring is also fixedly provided on the side wall of the collar; multiple sets of connecting brackets are slidably provided on the connecting ring; and a connecting piece is provided at the other end of each set of connecting brackets.

[0012] Preferably, the connecting frame and the connecting piece are rotatably connected.

[0013] Preferably, the connecting piece is made of a flexible material.

[0014] Preferably, the suction cup 2 has multiple suction cups evenly spaced on the connecting piece.

[0015] Preferably, a connecting rod is fixedly provided on the connecting frame.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: (1) The automotive sheet metal surface dent repair device includes a suction cup 1; multiple sets of connecting plates are provided around the suction cup 1; each of the multiple sets of connecting plates is provided with a suction cup 2; the multiple sets of connecting plates can rotate around the suction cup 1; by adjusting the positional relationship between the multiple sets of connecting plates and the suction cup 1, the multiple sets of suction cup 2 and the suction cup 1 can be adapted to the shape of the dent; by pulling the multiple sets of suction cup 2 and the suction cup 1 away from the automotive surface, the dent can be repaired. By moving the multiple sets of connecting plates, since the connecting plates are rotatably connected to the connecting frame, and the connecting frame is slidably set on the connecting ring, moving the connecting plates can make the connecting frame rotate flexibly around the connecting ring. At the same time, the flexible characteristics of the connecting plates themselves can adapt to the curvature of the dented surface, so that the multiple suction cup 2 on the connecting plates can be aligned with different contour parts of the dent, and achieve full coverage of complex dents. The drive mechanism is activated, causing the lead screw to rotate. Since the lead screw is threadedly connected to the collar, and the collar slides along the support rod via a sliding bracket, the rotation of the lead screw translates into a smooth linear movement of the collar along the support rod. This causes suction cup one and multiple suction cups two to simultaneously approach the dented area on the car body until they are tightly adhered to the dented surface. At this point, the negative pressure generation mechanism inside suction cup one and multiple suction cups two ensures they firmly adhere to the dented surface, forming a multi-point, uniform adsorption structure. Finally, the drive mechanism is activated again, causing the lead screw to rotate in the opposite direction. This drives suction cup one and multiple suction cups two to simultaneously generate a uniform and continuous reverse pulling force, allowing the dent to slowly rise under uniform force and ultimately repair the dent. This allows multiple suction cups two to precisely conform to the complex contours of the car dent, thus adapting to different shapes of car dents and enhancing adaptability. Simultaneously, they can work in conjunction with suction cup one to increase the contact area with the dent, enhancing the stability of adsorption and removal. In addition, the evenly distributed suction cup one and multiple suction cups two can disperse and balance the pulling force during the pulling, preventing excessive local force from damaging the car body, while allowing the dented area to recover smoothly and improving the repair accuracy.

[0017] (2) The automotive sheet metal surface dent repair device includes a telescopic mechanism and a slide rail set on the side wall of the frame; the telescopic end of the telescopic mechanism is connected to a rack; the rack is slidably connected to the slide rail; the side wall of the frame is also provided with a support; the side wall of the support is rotatably connected to a gear through a rotating shaft; the gear is meshed with the rack. By activating the telescopic mechanism, the rack is driven to slide along the slide rail. Since the rack and the gear connected to the support through the rotating shaft mesh with each other, the sliding of the rack will drive the gear to rotate synchronously, thereby driving the mounting bracket fixedly connected to the rotating shaft to flip up and down, realizing the fine adjustment of the angle of the dent repair component, so that the suction cup can be accurately aligned with the dent of the car.

[0018] (3) The automotive sheet metal surface dent repair device includes a mounting bracket; the mounting bracket is fixedly connected to a rotating shaft; the side wall of the mounting bracket is provided with a telescopic mechanism two; the telescopic end of the telescopic mechanism two is connected to a connecting plate; a support rod is fixedly provided on the side of the connecting plate away from the telescopic mechanism two; a pressure block is fixedly provided on the other end of the support rod. By activating the telescopic mechanism two, its telescopic end pushes the connecting plate forward smoothly, driving the support rod to move forward synchronously until the pressure block at the end of the support rod tightly abuts against the flat area around the dent of the car. The pressure block pressing against the car body can provide stable support for the automotive sheet metal surface dent repair device, avoid the device from shifting during subsequent repair operations, and also provide a stable force base for suction cup one and multiple suction cups two to adsorb and pull out the dent of the car.

[0021] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0022] like Figure 1-3As shown in the figure, an embodiment of the present invention provides an automotive sheet metal surface dent repair device, including a frame 1, a dent repair component 3, and an angle adjustment component 2. The dent repair component 3 is disposed on one side of the frame 1; the dent repair component 3 includes a suction cup 310; multiple sets of connecting pieces 314 are provided around the suction cup 310; each of the multiple sets of connecting pieces 314 is provided with a second suction cup 315; the multiple sets of connecting pieces 314 can rotate around the suction cup 310; by adjusting the positional relationship between the multiple sets of connecting pieces 314 and the suction cup 310, the multiple sets of second suction cups 315 and the suction cup 310 can be adapted to the shape of the dent; by pulling the multiple sets of second suction cups 315 and the suction cup 310 away from the automotive surface, the dent can be repaired. The angle adjustment component 2 is disposed between the frame 1 and the dent repair component 3, and is used to adjust the rotation angle of the dent repair component 3.

[0023] Further explanation: The angle adjustment component 2 includes a telescopic mechanism 21 and a slide rail 23 located on the side wall of the frame 1; the telescopic end of the telescopic mechanism 21 is connected to a rack 22; the rack 22 is slidably connected to the slide rail 23; the side wall of the frame 1 is also provided with a support 25; the side wall of the support 25 is rotatably connected to a gear 24 via a rotating shaft; the gear 24 meshes with the rack 22. Activating the telescopic mechanism 21 causes the rack 22 to slide along the slide rail 23. Since the rack 22 and the gear 24 rotatably connected to the support 25 via a rotating shaft mesh with each other, the sliding of the rack 22 drives the gear 24 to rotate synchronously, thereby causing the mounting bracket 31, which is fixedly connected to the rotating shaft, to flip up and down, achieving fine-tuning of the angle of the dent repair component 3, allowing the suction cup 310 to be precisely aligned with the dent on the car.

[0024] Further explanation: The dent repair component 3 includes a mounting bracket 31; the mounting bracket 31 is fixedly connected to a rotating shaft; a telescopic mechanism 32 is provided on the side wall of the mounting bracket 31; a connecting plate 33 is connected to the telescopic end of the telescopic mechanism 32; a support rod 34 is provided on the side of the connecting plate 33 opposite to the telescopic mechanism 32; a pressure block 35 is fixedly provided at the other end of the support rod 34. Activating the telescopic mechanism 32 causes its telescopic end to push the connecting plate 33 forward smoothly, causing the support rod 34 to move forward synchronously until the pressure block 35 at the end of the support rod 34 firmly abuts against the flat area around the dent on the car body. The pressure block 35 pressing against the car body provides stable support for the dent repair device on the car's sheet metal surface, preventing displacement of the device during subsequent repair operations, and also provides a stable force base for the suction cup 310 and multiple suction cups 315 to adsorb and remove the dent.

[0025] Further, the side wall of the mounting bracket 31 is also provided with a drive mechanism 36; the drive end of the drive mechanism 36 is connected to a lead screw 37; a limiting pad 38 is fixedly provided at the end of the lead screw 37 away from the mounting bracket 31; a collar 39 is threadedly connected to the lead screw 37; a suction cup 310 is fixedly provided on the collar 39. A sliding frame 316 is fixedly provided on the side wall of the collar 39; the sliding frame 316 is a telescopic structure; the other end of the sliding frame 316 is slidably connected to the support rod 34; the side wall of the connecting plate 33 is provided with a telescopic mechanism 317; the telescopic end of the telescopic mechanism 317 is connected to the support rod 34; a groove 318 is also provided on the side wall of the connecting plate 33; the support rod 34 is slidably connected in the groove 318. Activating the drive mechanism 36 causes the lead screw 37 to rotate. Since the lead screw 37 is threadedly connected to the collar 39, and the collar 39 is slidably engaged with the support rod 34 via the sliding frame 316, the rotation of the lead screw 37 is converted into a smooth linear movement of the collar 39 along the support rod 34. This allows the suction cup 310 and multiple suction cups 315 to approach the car body and adhere to the dent, or to move the suction cups 310 and multiple suction cups 315 away from the car body and pull the dent outward. Alternatively, activating the telescopic mechanism 317 can drive the support rod 34 to slide along the groove 318, thereby adjusting the position of the pressure block 35 on the car surface, ensuring that the pressure block 35 avoids the dent.

[0026] To further explain, a connecting ring 311 is also fixedly provided on the side wall of the collar 39; multiple sets of connecting brackets 312 are slidably provided on the connecting ring 311; and a connecting piece 314 is provided at the other end of each set of connecting brackets 312. The connecting brackets 312 and the connecting pieces 314 are rotatably connected. The multiple sets of connecting pieces 314 can be moved according to the shape of the dent in the car. Since the connecting pieces 314 are rotatably connected to the connecting brackets 312, and the connecting brackets 312 are slidably set on the connecting ring 311, moving the connecting pieces 314 can make the connecting brackets 312 rotate flexibly around the connecting ring 311. At the same time, the flexibility of the connecting pieces 314 can adapt to the curvature of the dented surface, so that the multiple suction cups 315 on the connecting pieces 314 can be aligned with different contour parts of the dent, achieving full coverage of complex dents. Multiple suction cups 315 can precisely conform to the complex contours of car dents, thus adapting to different shapes of car dents and enhancing adaptability. They also work in conjunction with suction cup 310 to increase the contact area with the car dent, enhancing the stability of adsorption and removal. Furthermore, the evenly distributed suction cups 310 and multiple suction cups 315 disperse and balance the pulling force during removal, preventing excessive localized force from damaging the car body, while allowing the dent to recover smoothly from the force, improving repair accuracy. The connecting piece 314 is made of flexible material, allowing multiple suction cups 315 to fit tightly against the car dent. Multiple suction cups 315 are evenly spaced on the connecting piece 314, thus evenly covering the corresponding dent area of ​​the connecting piece 314, forming multi-point adsorption in conjunction with suction cup 310, increasing the overall adsorption area and preventing detachment due to insufficient local adsorption. A connecting rod 313 is fixedly installed on the connecting frame 312, increasing the strength of the connecting frame 312.

[0027] The working principle of this invention is as follows: During operation, the frame 1 is first pushed to the side of the dent on the car body, ensuring that the entire car body panel dent repair device is in a convenient and stable working position. Then, the telescopic mechanism 1 21 is activated, driving the rack 22 to slide along the slide rail 23. Since the rack 22 and the gear 24 connected to the support 25 by a rotating shaft mesh with each other, the sliding of the rack 22 will drive the gear 24 to rotate synchronously, thereby driving the mounting bracket 31, which is fixedly connected to the rotating shaft, to rotate up and down, realizing the fine adjustment of the angle of the dent repair component 3, so that the suction cup 1 310 is precisely aligned with the dent on the car body. Next, the telescopic mechanism 2 32 is activated, and its telescopic end pushes the connecting plate 33 forward smoothly, driving the support rod 34 to move forward synchronously until the pressure block 35 at the end of the support rod 34 is tightly pressed against the flat part around the dent on the car body. The telescopic mechanism 317 can also be activated, driving the support rod 34 to slide along the slide groove 318, thereby adjusting the position of the pressure block 35 pressing on the car surface, so that the pressure block 35 avoids the dent on the car body.

[0028] Then, according to the shape of the dent, multiple sets of connecting pieces 314 are moved. Since the connecting pieces 314 are rotatably connected to the connecting frame 312 and the connecting frame 312 is slidably set on the connecting ring 311, moving the connecting pieces 314 can make the connecting frame 312 rotate flexibly around the connecting ring 311. At the same time, the flexible characteristics of the connecting pieces 314 can adapt to the curvature of the dented surface, so that the multiple suction cups 315 on the connecting pieces 314 can be aligned with different contour parts of the dent, achieving full coverage of complex dents.

[0029] The drive mechanism 36 is then activated, causing the lead screw 37 to rotate. Since the lead screw 37 is threadedly connected to the collar 39, and the collar 39 slides with the support rod 34 via the sliding bracket 316, the rotation of the lead screw 37 translates into a smooth linear movement of the collar 39 along the support rod 34. This causes the first suction cup 310 and multiple second suction cups 315 to simultaneously approach the dented area on the car body until they are tightly adhered to the dented surface. At this point, the negative pressure generation mechanism inside the first suction cup 310 and multiple second suction cups 315 firmly adheres to the dented surface, forming a multi-point, uniform adsorption structure. Finally, the drive mechanism 36 is activated again, causing the lead screw 37 to rotate in the opposite direction. This drives the first suction cup 310 and multiple second suction cups 315 to simultaneously generate a uniform and continuous reverse pulling force, allowing the dented car body to slowly rise under uniform force, ultimately repairing the dent.

[0030] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
