In order to meet production needs and quality requirements, many different automotive interior manufacturing technologies have emerged, among which the covering of automotive interiors can significantly enhance the aesthetics of the vehicle.

[0003] Since most of the sides of automotive interior parts are curved, and existing technologies make it difficult to fit the curved parts tightly, the interior parts are not fully covered, and problems such as peeling edges are easy to occur. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic edge-wrapping device for automotive interior parts, so as to solve the technical problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An automatic edge-wrapping device for automotive interior trim includes a base, guide rails on both sides of the upper end of the base, an adjustment component inside the guide rails, a lifting rod at the top of the adjustment component, a trim panel fixing component at the upper end of the lifting rod, and hydraulic telescopic rods at the four corners of the base. A connecting frame is provided at the top of the hydraulic telescopic rods, and a positioning groove is provided at the top of the connecting frame. An expansion component is provided inside the positioning groove.

[0007] The decorative panel fixing assembly includes an extension platform, the bottom of which is provided with a mounting groove for connecting to a lifting rod, an expansion platform rotatably provided at the top of the extension platform, a clamping groove is provided at the top of the expansion platform, a clamping plate assembly is provided inside the clamping groove, and electric telescopic rods are rotatably provided on both sides of the expansion platform, with the other end of the electric telescopic rods rotatably connected to the side wall of the extension platform.

[0008] Furthermore, the adjustment assembly includes a bottom ring and a top plate. The bottom ring is fixedly installed at the bottom end of the base and located at the edge of the guide rail. The top plate is fixedly installed at the top end of the base and located at the edge of the guide rail. A support plate is slidably installed inside the bottom ring. A slide rod inserted into the guide rail is installed at the top end of the support plate. A locking plate is threadedly connected to the top end of the outer peripheral wall of the slide rod.

[0009] Furthermore, the lifting rod includes a connecting sleeve, which is fixedly mounted on the top of the sliding rod. An extension rod is threadedly connected to the top of the connecting sleeve, and an insert is rotatably mounted on the top of the extension rod. The insert is fixed inside the mounting groove by bolts.

[0010] Furthermore, the clamping plate assembly includes a sliding block, and the top of the expansion platform and both sides of the clamping groove are provided with sliding grooves for installing the sliding block.

[0012] Furthermore, the expansion assembly includes a pressure plate, the side wall of which is connected to the top wall of the connecting frame via a hinge, a pressure platform at the bottom of the pressure plate, which cooperates with the support ring, and an air pump is installed inside the pressure platform.

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] 1. The automatic edge-wrapping device for automotive interior trim is provided in which the axis of symmetry of the guide rail and the expansion component is offset. Therefore, when the protective film slides down, it contacts the automotive trim panel at an angle. At this time, the protective film can cover the center of the automotive trim panel from one side. The angle of the automotive trim panel can be adjusted by the electric telescopic rod so that the edge of the automotive trim panel can contact the protective film. This allows the protective film to adhere tightly to the edge of the automotive trim panel, improving the wrapping effect.

[0015] 2. This automatic edge-wrapping device for automotive interior trim uses a pressure table and a support ring to fix the protective film. Then, an air pump inflates the gap between the protective film and the pressure table, causing the protective film to expand to the bottom and form an arc shape. The arc-shaped protective film can expand fully, effectively preventing the protective film from folding when wrapping automotive trim panels, and further improving the wrapping effect.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Example:

[0025] Reference Figure 1 - Figure 5 This utility model discloses an automatic edge-wrapping device for automotive interior parts, including a base 1, guide rails 2 on both sides of the upper end of the base 1, an adjustment component 3 inside the guide rails 2, a lifting rod 4 at the top of the adjustment component 3, a trim panel fixing component 5 at the upper end of the lifting rod 4, hydraulic telescopic rods 6 at the four corners of the base 1, a connecting frame 7 at the top of the hydraulic telescopic rods 6, a positioning groove 8 at the top of the connecting frame 7, and an expansion component 9 inside the positioning groove 8.

[0026] The decorative panel fixing assembly 5 includes an extension platform 51. The bottom end of the extension platform 51 is provided with a mounting groove 52 for connecting with the lifting rod 4. An expansion platform 53 is rotatably provided at the top end of the extension platform 51. A clamping groove 54 is opened at the top end of the expansion platform 53. A clamping plate assembly 55 is provided inside the clamping groove 54. Electric telescopic rods 56 are rotatably provided on both sides of the expansion platform 53, and the other end of the electric telescopic rods 56 is rotatably connected to the side wall of the extension platform 51.

[0027] In this embodiment, when covering the interior parts of the car, the interior parts of the car are first fixed to the top of the two sets of trim fixing components 5 in the same guide rail 2. Before fixing, the position of the adjusting component 3 inside the guide rail 2 is controlled so that the trim fixing component can correspond to the reinforcing rib of the car trim panel. The reinforcing rib of the trim panel is fixed to the top of the trim fixing component. The larger flat end of the car trim panel is made to face upward by adjusting the lifting rod 4.

[0028] After the automotive trim panel is installed, place the covering material or protective film inside the positioning groove 8, ensuring the edge of the protective film aligns with the support ring 81 located at the edge of the positioning groove 8. Then, fasten the expansion assembly 9 onto the top of the linkage frame and press the protective film and support ring 81 together. Figure 5 As shown, the protective film is inflated by the expansion assembly 9, causing it to expand. The connecting frame 7 moves downwards via the hydraulic telescopic rod 6, bringing the protective film into contact with the top surface of the car trim panel. This downward movement continues until the protective film and the car trim panel are fully in contact. After complete contact, the extension platform 51 is deflected by the extension and retraction of the electric telescopic rods 56 on both sides, thus deflecting the car trim panel. Because the guide rail 2 and the axis of symmetry of the expansion assembly 9 are offset, the protective film slides downwards at an angle, making contact with the car trim panel. Figure 5 As shown, reference numeral 500 represents a protective film, and reference numeral 510 represents a car trim panel. Therefore, as the protective film continues to move downwards, it can cover the car trim panel from one side to the center, and the angle of the car trim panel can be adjusted by the electric telescopic rod 56 to improve the covering effect.

[0029] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 5 As shown, the adjustment assembly 3 includes a bottom ring 31 and a top plate 32. The bottom ring 31 is fixedly installed at the bottom end of the base 1 and located at the edge of the guide rail 2. The top plate 32 is fixedly installed at the top end of the base 1 and located at the edge of the guide rail 2. A support plate 33 is slidably installed inside the bottom ring 31. A slide rod 34 inserted into the guide rail 2 is installed at the top end of the support plate 33. A locking plate 35 is threadedly connected to the top end of the outer peripheral wall of the slide rod 34.

[0030] In this embodiment, the support plate 33 and the slide rod 34 are installed inside the guide rail 2 by the bottom ring 31 to prevent the slide rod 34 from falling off. The locking plate 35 is connected by a thread. When adjusting the position of the slide rod 34, the locking plate 35 is moved upward by the thread, so that the bottom side of the locking plate 35 is separated from the top plate 32. At this time, the friction between the support plate 33 and the base 1 is reduced, so that the slide rod 34 can be easily pushed manually. When adjusted to the required position, the locking plate 35 is moved downward and fits tightly against the top plate 32, which increases the friction between the adjustment assembly 3 and the base plate, thereby fixing the slide rod 34. This achieves the purpose of adjusting the trim panel fixing assembly 5 so that it corresponds to the reinforcing ribs inside the car trim panel, thereby improving the convenience of installing the car trim panel.

[0031] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the lifting rod 4 includes a connecting sleeve 41, which is fixedly installed at the top of the slide rod 34. An extension rod 42 is threadedly connected to the top of the connecting sleeve 41, and an insert block 43 is rotatably installed at the top of the extension rod 42. The insert block 43 is fixed inside the mounting groove 52 by bolts.

[0032] In this embodiment, the lifting rod 4 is used to adjust the height of the trim panel fixing components 5 at different positions, so that the relatively flat side of the car trim panel faces upward during installation, and the protective film can quickly cover the car trim panel when it falls, thereby improving the covering efficiency.

[0033] When adjusting the height of the lifting rod 4, rotate the extension rod 42 so that the extension rod 42 moves inside the connecting sleeve 41 under the influence of the thread, thereby achieving the purpose of adjusting the height of the lifting rod 4.

[0034] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the clamping plate assembly 55 includes a sliding block 551. The top of the expansion platform 53 and the two sides of the clamping groove 54 are provided with sliding grooves 552 for installing the sliding block 551. The bottom wall of the sliding groove 552 is provided with an adjusting screw 553, and the bottom end of the sliding block 551 is provided with a guide groove 554 that is threadedly engaged with the adjusting screw 553.

[0035] In this embodiment, the distance between the sliding blocks 551 on both sides is controlled by rotating the adjusting screws 553 on both sides, so as to clamp the reinforcing ribs of the car trim panel.

[0036] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 5 As shown, a support ring 81 is provided on the bottom side of the positioning groove 8, and an anti-slip strip is provided on the top of the support ring 81.

[0037] In this embodiment, the support ring 81 and the anti-slip strip are used to position the edge of the protective film.

[0038] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 5 As shown, the expansion assembly 9 includes a pressure plate 91. The side wall of the pressure plate 91 is connected to the top wall of the connecting frame 7 via a hinge. A pressure platform 92 is provided at the bottom end of the pressure plate 91. The pressure platform 92 cooperates with the support ring 81. An air pump 93 is provided inside the pressure platform 92.

[0039] In this embodiment, when the protective film is installed inside the positioning groove 8 and the edge of the protective film is pressed tightly against the anti-slip strip on the top of the support ring 81, the pressure plate 91 is fastened to the top of the positioning groove 8 by a hinge, and at this time, the bottom edge of the pressure table 92 presses against the upper surface of the support ring 81. Figure 5 As shown, the protective film can be fixed by the pressure table 92 at this time, and the gap between the protective film and the pressure table 92 can be inflated by the air pump 93, causing the protective film to expand towards the bottom and form an arc shape, as shown. Figure 5 As shown, the arc-shaped protective film can expand fully, effectively preventing folding when covering car trim panels and further improving the covering effect.

[0040] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
