In this document, "one" means not only "only one" but also a case of "more than one". The term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items. The terms "first," "second," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The first embodiment is as follows: a connecting structure for an inner plate and an outer plate of a trunk lid.

As shown in fig. 1 (the outer cover 10 and the inner panel 20 are shown only in relevant parts because of the design relating to the new model), the trunk lid inner and outer panel connecting structure of the present embodiment is used for a trunk lid of a vehicle, and includes the outer cover 10, the inner panel 20, and one reinforcement 30. The outer cover 10 has a mounting groove 11 extending in the width direction, the mounting groove 11 having a recess structure opened toward the rear of the vehicle for mounting the final assembly parts. The outer edge of the inner panel 20 is adhesively bonded to the outer cover 10 by means of prior art hems and structural glue (the above-described hems structure is not shown in the drawings), and the inner panel 20 is also attached to the mounting groove 11. As shown in fig. 6, the reinforcement 30 has a first overlapping portion 31, a connecting portion 32 and a second overlapping portion 33 connected in sequence, the first overlapping portion 31 is connected to the outer cover 10, the second overlapping portion 33 is connected to the inner panel 20, the connection point of the second overlapping portion 33 and the inner panel 20 is located below the mounting groove 11 and spaced apart from the connection point of the mounting groove 11 and the inner panel 20, that is, a set distance is provided, so that a cavity 40 having a closed cross section is formed between the reinforcement 30 and the side wall below the mounting groove 11, constituting a partial cavity reinforcement structure.

The overall rigidity of the flat-plate-like structure, the groove-like structure with one open side, the structure with weak links will be much lower than the structure with closed cross-section, given the same weight of the material used. For example, thin-walled parts, especially cylindrical structures with a closed cross-section, rectangular or circular cross-section, have a significant difference in bending stiffness compared to a slot-like structure with a slit cut in the longitudinal direction or with one side open, and a difference in torsional stiffness of even more than two orders of magnitude. Therefore, the structure with the closed section can greatly improve the local bending rigidity and the torsional rigidity, thereby playing a role in strengthening the opening structure formed by the mounting groove 11 and eliminating the weak link of the whole trunk lid. The dimension of the reinforcing member 30 in the width direction can be set according to the rigidity requirement. As a variation of this embodiment, the reinforcement members 30 may be disposed in a plurality in the width direction, or the reinforcement members 30 may be disposed above the mounting groove 11, or the reinforcement members 30 may be disposed on both the upper and lower sides of the mounting groove 11, and may be selected according to the specific structure of the trunk lid.

As shown in fig. 2 to 5, the outer cover 10 includes an upper cover 12, a middle piece 13 and a lower cover 14, wherein the middle piece 13 is of a groove structure including an upper side plate 131, a groove bottom 132 and a lower side plate 133 which are connected in sequence; the inner plate 20 is connected to the trough bottom 132. The upper cover 12 has a first flange 121 that is overlapped to the upper side plate 131, and the lower cover 14 has a second flange 141 that is overlapped to the lower side plate 133; the first flange 121, the middle piece 13 and the second flange 141 together form the mounting groove 11. The provision of the first and second flanges 121 and 141 allows the joint of the outer cover 10 to be located in the mounting groove 11, i.e., in a gray area not visible to the user, reducing the appearance requirements of the joint, and thus also allowing for sealing and corrosion protection simply by bonding and painting PVC. Meanwhile, the first flange 121 and the second flange 141 also form part of two side surfaces of the mounting groove 11, so that the depth of the groove-shaped structure of the middle piece 13 is reduced when the depth of the mounting groove 11 is larger, and the stamping difficulty is reduced. It is also advantageous to divide the outer cover 10 into three pieces so that materials having different thicknesses can be used, and the upper cover 12 and the lower cover 14 of this embodiment are made of 0.7mm thick galvanized steel plates, while the intermediate member 13 is made of 1.0mm galvanized steel plates, so that the structure of the intermediate member 13 is reinforced. Since the intermediate member 13 is invisible and has no requirement on appearance, as shown in fig. 4, the intermediate member 13 is provided with a plurality of three-dimensional structures, and can also have high rigidity.

The connection between the first flange 121 and the upper side plate 131 and the connection between the lower side plate 133 and the second flange 141 are spot welded connections, the first flange 121 and the second flange 141 each have a toothed edge, and the spot welding points of the spot welded connections are located in a plurality of toothed protrusions of the toothed edge, see the illustrated first toothed protrusion 1211 and second toothed protrusion 1411. The tooth-shaped bulges are arranged according to the number and the positions of designed welding spots, so that the welding positions can be quickly found during manual welding, and the number and the positions of the welding spots can be ensured to be accurate.

As shown in fig. 4, the groove bottom 132 is provided with two multifunctional positioning holes 1321, and the multifunctional positioning holes 1321 are used for positioning the intermediate member 13 at the time of welding the outer cover 10 and for positioning the left and right two final assembly members mounted in the mounting groove 11 at the same time. As shown in fig. 7, the inner plate 20 has two bosses 21, and the bosses 21 are used to be connected to the mounting groove 11. The draft of the boss 21 is 50 degrees to make full use of the boss 21 to form a three-dimensional connection structure and play a role in reinforcing the weak position of the rigidity at the bottom of the mounting groove 11. As can be seen from the side view of fig. 1, the boss 21 makes the connection between the bottom of the mounting groove 11 and the inner plate 20 no longer a weak flat plate-like laminated structure, but a three-dimensional connection with a space structure, thereby significantly improving the local rigidity and strength.

As shown in fig. 6, the reinforcing member 30 further has a lightening hole 34, a reinforcing flange 35, a reinforcing groove 36, a glue coating slot 37, and the like, so that the reinforcing member 30 has a compact structure, a light weight, and a high rigidity. The second overlapping portion 33 and the inner panel 20 are welded to form an assembly, and then the first overlapping portion 31 and the lower cover 14 are bonded by a support adhesive at a trunk lid assembly assembling station. As shown in FIG. 8, the boss 21 is provided with a CMT weld hole 22; the boss 21 and the slot bottom 132 are joined by a CMT MIG brazing process. The CMT weld holes 22 are kidney holes.

As a variation of this embodiment, the number and positions of the reinforcing members 30 can be flexibly set according to the requirement, for example, the reinforcing members can be set at weak positions between the inner and outer plates where deformation is large after loading according to a finite element calculation structure. Also the shape, position and number of the convex platform 21 can be set according to the need, because the CMT MIG brazing also has a certain gap filling function, the requirement of the shape and position tolerance of the convex platform 21 can be properly reduced, because the over-positioning problem is not necessary to worry, the number can be set to be more, and the requirement of the positioning scheme and the clamp design between the inner plate and the outer plate is also reduced.

Example two: a connecting structure for inner and outer plates of a luggage case.

The luggage inner and outer panel connection structure of the present embodiment differs from the first embodiment in that, as shown in fig. 9, the outer cover 10 is of a two-piece design, including an upper cover 12 and a lower cover 14; the upper covering part 12 comprises a first flanging 121 and a first bending part 122 which are sequentially connected, the main body of the upper covering part 12, the first flanging 121 and the first bending part 122 are in a Z-shaped step shape, the lower covering part 14 comprises a second flanging 141 and a second bending part 142 which are sequentially connected, the Z-shaped step shape is also formed, the first bending part 122 and the second bending part 142 are connected in an overlapped mode to form the bottom of the mounting groove 11, and the first flanging 121 and the second flanging 141 respectively form two side faces of the mounting groove 11.

The design of the one-piece outer cover 10 according to the present embodiment and the first embodiment may be selected according to the depth of the mounting groove 11, the thickness and material of the plate material, and the specific stamping process. Generally, the one-piece design is the simplest structure and is suitable for the situation where the depth and the inclination of the installation groove 11 are small, the three-piece design of the first embodiment is the best in adaptability and relatively complex in structure, while the embodiment is suitable for the situation where the depth and the inclination of the installation groove 11 are moderate, and the first bending part 122 and the second bending part 142 which are arranged in an overlapped mode are easily connected through spot welding and gluing.

Example three: a vehicle is provided.

The vehicle of the present embodiment includes a trunk lid, and a combination tail lamp, a rear-view camera module, a rear-lid opening handle, and a rear-lid trim module mounted to the trunk lid. The trunk cover comprises a trunk cover inner plate and outer plate connecting structure of the first embodiment; wherein the mounting groove 11 runs through the width of the whole trunk lid, the combined tail lamp is arranged at the two ends of the mounting groove 11, the rearview camera module and the rear lid opening handle are arranged in the middle, and the other parts are covered by the rear lid decoration module. Because mounting groove 11 provides sufficient installation space, still can reserve installation space for vehicle intelligent novel module such as laser radar.

The plurality of final assembly components can also be assembled into a pre-assembly, and then the pre-assembly is assembled on the trunk cover on the final assembly line, so that the takt time of the final assembly line can be saved.

The foregoing is only a preferred embodiment of the present application and the technical principles employed, and various obvious changes, rearrangements and substitutions may be made without departing from the spirit of the application. Other advantages and effects of the present application will be readily apparent to those skilled in the art from the disclosure herein.
