[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0026] like Figures 1 to 5 As shown, a folding device for automobile opening and closing parts includes a base 1, a polygonal groove 11 is provided on the top surface of the base 1, a fetal membrane seat 2 is connected to the polygonal groove 11 for sliding up and down, and a fetal membrane 3 is detachably connected to the top surface of the fetal membrane seat 2; the fetal membrane seat 2 is connected to a lifting drive member 4 for driving it to move up and down; a folding assembly 5 is provided on at least one side of the polygonal groove 11, and the folding assembly 5 includes a sliding seat 51 and two folding knives 52 arranged on the upper and lower sides of the sliding seat 51 facing the fetal membrane 3; the sliding seat 51 is horizontally slidably connected to the base 1, and the sliding seat 51 is connected to a drive assembly 6 for driving it to move toward or away from the polygonal groove 11.

[0027] Specifically, such as Figure 2 and 3 As shown, the sliding seat 51 is slidably connected to the base 1 via two sliding assemblies 7. The sliding assembly 7 includes a track plate 71 and a sliding plate 72 slidably mounted on the track plate 71. The track plate 71 is connected to the base 1, and the sliding plate 72 is connected to the sliding seat 51. The track plate 71 is connected to two upper limit members 73 for limiting the sliding plate 72. The two upper limit members 73 are spaced apart. A protrusion is provided on the side of the sliding seat 51, and the protrusion is restricted from moving between the two upper limit members 73. The two upper limit members 73 limit the movement of the protrusion, thereby achieving the purpose of limiting the movement of the sliding seat 51. The track plate 71 is also connected to an end limit member 74 for limiting one end of the track plate 71 to prevent the track plate 71 from moving too far and damaging the vehicle's opening and closing parts.

[0028] Furthermore, the track plate 71 is connected to a second limiting member 75 for slidingly limiting the sliding seat 51 . The second limiting member 75 is preferably a limiting column.

[0029] In this embodiment, by setting two sliding components 7, it can be ensured that the sliding seat 51 can slide stably relative to the base 1, and at the same time the connection strength between the sliding seat 51 and the base 1 is improved, thereby preventing the folding component 5 from flipping upward relative to the base 1 during the pre-folding and final folding processes, thereby affecting the folding effect.

[0030] like Figure 4 As shown, the drive assembly 6 includes a first connecting block 61, a second connecting block 62, a rotating arm 63, a connecting arm 64, and a linear drive member 65. The first connecting block 61 is connected to the sliding seat 51; one end of the connecting arm 64 is hinged to the connecting arm 64; the second connecting block 62 is connected to the base 1; the rotating arm 63 has three connecting ends, two of which are hinged to the other end of the connecting arm 64 and the second connecting block 62, respectively, and the third connecting end is hinged to an articulated joint 66, which is connected to the driving end of the linear drive member 65. The linear drive member 65 is preferably a cylinder.

[0031] In this embodiment, the linear drive member 65 drives the rotating arm 63 to rotate relative to the second connecting block 62, driving the connecting arm 64 to rotate, and then pushing the first connecting block 61 and the sliding seat 51 connected to the first connecting block 61 to move linearly together, so that the two folding knives 52 can move smoothly towards or away from the fetal membrane 3.

[0032] In this embodiment, the edge-folding knife 52 comprises a knife seat and a plurality of knife body blocks mounted on the knife seat. The edge-folding knife 52 is prior art and will not be described in detail herein.

[0033] like Figure 5 As shown, the membrane seat 2 is hollow and has an opening facing downward. The shape of the membrane seat 2 is adapted to the polygonal groove 11. The membrane 3 is detachably connected to the top surface of the membrane seat 2. When folding, the appropriate membrane 3 can be selected and installed on the membrane seat 2 according to the product type and model.

[0034] The inner top surface of the membrane seat 2 is connected to a connecting block 21 having a slide groove. A lifting drive 4 is located within the membrane seat 2 and is slidably connected to the base 1 via a sliding frame 8. The driving end of the lifting drive 4 is connected to an inner slider 41, which can slide horizontally into or out of the slide groove. The sliding frame 8 can slide out from the side of the base 1. In this embodiment, the lifting drive 4 is preferably a hydraulic cylinder.

[0035] During use, by pulling the sliding frame 8 outward, the inner slider 41 can be withdrawn from the sliding groove, thereby separating the lifting drive member 4 from the fetal membrane seat 2. Continuing to pull the sliding frame 8 outward, the lifting drive member 4 can be moved out of the base 1 for easy maintenance and replacement; by pushing the sliding frame 8 inward, the inner slider 41 can be slid into the sliding groove, thereby connecting the lifting drive member 4 to the fetal membrane seat 2, and installation is also relatively convenient.

[0036] A side surface of the fetal membrane seat 2 is provided with an avoidance groove 22 for avoiding the lifting drive member 4 .

[0037] In this embodiment, by providing a hollow fetal membrane seat 2 with an opening facing downward, the weight of the fetal membrane seat 2 can be reduced. It can also ensure a stable sliding connection between the fetal membrane seat 2 and the base 1 without increasing the occupied space in the height direction, thereby improving the folding quality.

[0038] The utility model relates to a folding device for automobile opening and closing parts. When in use, the fetal membrane 3 is used to support the automobile opening and closing parts to be folded; under the drive of the driving component 6, the sliding seat 51 moves toward the direction of the polygonal groove 11, so that the folding knife 52 below moves to the pre-folding position; under the drive of the lifting driving component 4, the fetal membrane seat 2 moves upward, driving the fetal membrane 3 to move upward to the pre-folding position, so that the fetal membrane 3 and the folding knife 52 below cooperate to pre-fold the automobile opening and closing parts; after the pre-folding is completed, the driving component 6 drives the sliding seat 51 The folding blade 52 moves away from the polygonal groove 11, separating the folding blade 52 from the automobile opening and closing part; the membrane seat 2 continues to move upward, driving the membrane 3 to move upward to the middle position; the driving assembly 6 drives the sliding seat 51 to move toward the polygonal groove 11, so that the upper folding blade 52 moves to the final folding position; the membrane seat 2 continues to move upward, driving the membrane 3 to move upward to the final folding position, so that the membrane 3 cooperates with the upper folding blade 52 to perform the final folding of the automobile opening and closing part, thereby completing the folding operation of the automobile opening and closing part. During the pre-folding and final folding processes, the folding assembly 5 does not flip over, thereby making the folding quality more stable and reliable, and preventing the surface of the automobile opening and closing part from being worn.
