Detailed Description
The present invention will be further explained in detail with reference to the accompanying drawings.
As shown in fig. 1 the utility model discloses van-type semitrailer back door structure, include: a panel 1, a frame 2, a hinge 3, a locking bar 4 and a sealing mechanism 5.
The watch plate 1 is a whole steel plate, and referring to fig. 3, the watch plate 1 includes a body 11 and folded edges 12 folded from the periphery of the body 11, and the folded edges 12 wrap the frame 2.
The frame 2 is formed by welding a transversely arranged beam 21 and a vertically arranged beam 22. Referring to fig. 2, whether the beams 21, 22 include a top wall 23 parallel to and apart from the face plate 1, two side walls 24 respectively bent vertically from both ends of the top wall 23 toward the face plate 1, and a bottom wall 25 bent vertically from at least one of the side walls 24 toward a direction parallel to the face plate 1, the bottom wall 25 is welded snugly to the inside of the face plate 1. The bottom wall 25 is provided to facilitate the attachment and welding between the beams 21, 22 and the skin panel 1.
Where the beams 21 are arranged transversely and the beams 22 are arranged vertically in the frame 2, the beams 22 are one and unbroken; the beam 21 is completely broken at its intersection with the beam 22 or only the top wall remains and the rest is broken. Due to the use of the frame 2, the surface plate 1 can be a steel plate with a thickness within 1.2 mm.
The hinge 3 is fixed by rivets to the ends of the transversely disposed beams 21.
The lock rod 4 is built-in and is arranged in a cavity formed by the vertically arranged beam 22 and the surface plate 1 in a penetrating way.
As shown in fig. 3, in the welding condition between the exterior panel 1 and the frame 2, the vertical plate where the frame 2 is attached to the folded edge 11 of the exterior panel 1, that is, the side wall 26 of the beam 21, 22 has a first straight section 261, a bent section 262 and a second straight section 263, wherein the bent section 262 has a dimension the same as the thickness of the exterior panel 1, and the folded edge 12 of the exterior panel 1 is flush with the first straight section 261 after being attached to the second straight section 263, which not only facilitates welding, but also makes the side surface of the door smooth and beautiful.
In addition, the bottom walls 25 of the beams 21 and 22 are tightly attached to the surface plate 1 and welded together in a laser welding mode, so that the surface plate 1 is almost free of thermal deformation in the welding process, and the smooth and flat effect of the surface plate 1 after welding is ensured.
As shown in fig. 4, the vertically arranged beam 22 cooperates with the first reinforcing members 6, the first reinforcing members 6 are arranged on both inner sides of the beam 22, each first reinforcing member 6 has a first wall 61 abutting the top wall of the beam 22 and a second wall 62 abutting the side wall of the beam 22, wherein the second wall 62 further includes a first flat plate 621, a second flat plate 623 and an arc plate 622 arched between the two flat plates 621, 623, and the two flat plates 621, 623 abut the side wall of the beam 22.
As shown in fig. 5, the strength and rigidity of the frame 2 can be improved by fitting the second reinforcing member 7 to the intersection of the beams 21 and 22 and locating the second reinforcing member 7 on the side close to the opening of the intersection.
As shown in fig. 6, the intersection of the beams 21 and 22 is engaged with the third reinforcing member 8, and the third reinforcing member 8 is located on the other side of the intersection from the opening and spot-welded to the bottom wall 25 of the beam 21 and the bottom wall 25 of the beam 22, respectively, so that the strength and rigidity of the frame 2 can be further improved. The use of these reinforcing members 6, 7 and 8 improves the strength of the door panel, so that the weight of the door panel can be reduced.
The structure of the first reinforcing member 6 may be the structure shown in fig. 7, which has a first wall 61 attached to the top wall of the beam 22 and a second wall 62 attached to the side wall of the beam 22.
The structure of the first reinforcing member 6 may be the structure shown in fig. 8: the beams 21, 22 are constructed such that the bottom wall 25 extends inwardly to lie within the frame enclosed by the top wall 23 and the two side walls 24. At this time, the first reinforcing member 6 has a "[" shaped structure including a first wall 61 attached to the top wall 23, a second wall 62 attached to the side wall 24, and a third wall 63 attached to the bottom wall 25.
It should be noted that the frame 2 and the face plate 1 are welded by laser, and the first reinforcing member 6 and the beam 22 are welded by conventional resistance welding, so that the inner side of the door panel is neater.
Referring to fig. 9 and 10, the sealing mechanism 5 of the present invention includes a first sealing mechanism 51 and a second sealing mechanism 52. Wherein,
the first sealing mechanism 51 between the left door and the right door, as shown in fig. 9, includes a baffle 511, a bracket 512, and a rubber strip 513, where the baffle 511 may be a bent overhanging portion of the beam 22 or a welded independent strip, the bracket 512 includes a transition section 5121 extending horizontally toward the left door and an insertion section 5122 extending from the transition section 5121 to be bent inward vertically, and the rubber strip 513 is inserted on the insertion section 5122. Because the extension direction of the inserting section 5122 is perpendicular to the door panel surface, after the adhesive tape 513 is inserted, the inserting section 5122 and the adhesive tape 513 are both positioned in the gap between the two doors, and are not arranged in the inner side space of the door panel like the existing sealing mechanism, thereby saving the effective length of the inner space of the doors and improving the actual cargo space of the whole carriage.
The second sealing mechanism 52 between the door and the rest of the vehicle compartment, as shown in fig. 10, includes a bracket 521 and a rubber strip 522 inserted on the bracket 521, wherein the bracket 521 is a steel plate folded into a "Z" shape and welded to the frame 2. The bracket 521 includes a welding section 5211 attached to the inner side of the frame, a transition section 5212 extending from the welding section 5211 by bending inward in an inclined manner, and an insertion section 5213 extending from the transition section 5212 by bending outward in a direction parallel to the welding section 5211, wherein the adhesive tape 522 is inserted on the insertion section 522.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the embodiments of the present invention, so the protection scope of the present invention should be subject to the protection scope claimed in the claims.
