Detailed Description

In the description of the present invention, it should be understood that the terms "inside", "outside", "front", "back", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

The following description is made in detail with reference to the specific embodiments, and fig. 1 shows the schematic diagram of the rear cover plate tail supporting structure of the trunk of the present invention in the separated state, it can be clearly seen that the rear cover plate of the trunk of the present invention is composed of an inner trunk plate 1 and an outer trunk plate 2, both of which are integrated stamping parts. The shell of the automobile luggage rear cover plate is formed by buckling a luggage inner plate 1 and a luggage outer plate 2, and the outer edges of the two parts which are attached to each other are fixedly connected in a welding mode. At the rear of the trunk lid of the motor vehicle, a cavity structure 3 (as shown in fig. 2) is provided, i.e. the above-mentioned inner trunk panel 1 and outer trunk panel 2 have a gap in this region. In order to support the trunk outer panel 2, an abutting portion 4 is arranged in the cavity structure 3, and comprises a front end abutting tilting portion 41 and a tail end abutting tilting portion 42, wherein the front end abutting tilting portion 41 is arranged at a distance of 150mm from the bottom side edge 100 of the glass window opening; the aft closeout raised portion 42 opens around the trunk latch cover mounting plate opening (as shown in fig. 3). Compared with the traditional design scheme, the technical scheme can ensure the appearance smoothness of the trunk outer plate 2 by only adjusting the heights of the front end jacking tilting part 41 and the tail end jacking tilting part 42 in the actual assembly process. Therefore, when the die is used for punch forming, only the profile degree of the trunk outer plate 2 needs to be ensured, the requirement on the profile precision of the trunk inner plate 1 is not high, and the input cost of the die is greatly reduced. In addition, the technical scheme can effectively reduce the requirement of the assembly process on the positioning precision, and further improve the output efficiency of the production line.

As a further refinement of the front end raised portion and the rear end raised portion, the front end raised portion 41 is formed by a plurality of first bent rests 411 (as shown in fig. 4) provided on the trunk inner panel 1 and is manufactured by a press method. The rear raised portion 42 is formed by a second bent member 421 extending along the top wall of the opening of the trunk lock cover mounting plate and a third bent member 422 extending along the bottom wall of the opening of the trunk lock cover mounting plate (as shown in fig. 5), and is also formed by stamping. Thus, the rear cover plate of the automobile trunk has lower molding cost, and in the actual operation process, when the assembly gap is larger, the first bending abutting part 411, the second bending abutting part 421 and the third bending abutting part 422 are adjusted to be convenient for being matched with the outline of the trunk outer plate 2. Of course, an elastic adjusting pad (not shown) may be added to the abutting surfaces of the first bending abutting member 411, the second bending abutting member 421 and the third bending abutting member 422.

The quantity that the curved top of third bend leaned on piece 422 sets up to 2, carries out the equipartition along the width direction of suitcase lock lid mounting panel diapire to make suitcase planking 2 wait to reliably support, satisfy the requirement of supporting strength.

In order to improve the assembling efficiency and reduce the assembling difficulty, the trunk outer panel 2 is fixed with the first bending abutting piece 411, the second bending abutting piece 421 and the third bending abutting piece 422 in a bonding manner. The method specifically comprises the following steps: the abutting surfaces of the first bending abutting member 411, the second bending abutting member 421 and the third bending abutting member 422 are all provided with glue grooves 43 (as shown in fig. 4). The glue groove 43 is preferably U-shaped in cross-section. In addition, in the case of using the elastic adjusting shim, the specific arrangement is as follows: the glue groove 43 is correspondingly opened on the top surface of the resilient adjustment pad, and the resilient adjustment pad can be fixed to the first 411, the second 421 and the third 422 bending abutments by means of bolts or other detachable means.

Finally, in order to improve the bending strength of the first bending abutting member 411, the second bending abutting member 421 and the third bending abutting member 422 and to ensure the reliability of supporting the trunk outer panel 2, a reinforcing groove may be additionally provided thereon. The method comprises the following specific steps: a reinforcing groove 4111 is provided at a widthwise central line position on the first bending header 411. The reinforcing groove 4111 has a depth not less than 1.5 times the thickness of the plate of the first bent abutting member 411 and a width not less than 1/2 times the width of the first bent abutting member 411. The second 421 and third 422 folding abutments are arranged in analogy to the first 411 abutment.
