In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2, the connection structure is schematically shown to include a connection structure body 1, a first lap joint position 2, a second lap joint position 3, and a support member 4.
In the embodiment of the present application, a first lap joint site 2 for connecting the aluminum honeycomb 100 and a second lap joint site 3 for connecting the aluminum sheet 200 are respectively configured on the upper surface of the connecting structure body 1, and the difference in longitudinal height between the first lap joint site 2 and the second lap joint site 3 is equal to the difference in longitudinal thickness between the aluminum sheet 200 and the aluminum honeycomb 100.
The supporting member 4 is disposed on one side of the connecting structure body 1 and extends in a direction away from the connecting structure body 1, and the supporting member 4 is located below the first overlapping position 2 and is used for bearing the aluminum honeycomb 100. Specifically, in this application, because the connection structure body 1 is additionally provided, and the first lap joint position 2 and the second lap joint position 3 are respectively configured on the upper surface of the connection structure body 1, and the first lap joint position 2 is used for connecting the aluminum honeycomb 100, and the second lap joint position 3 is used for connecting the aluminum plate 200, in this way, it is possible to realize that the aluminum honeycomb 100 and the aluminum plate 200 which are different in thickness are connected, and the contact area between the first lap joint position 2 and the aluminum honeycomb 100 and the contact area between the second lap joint position 3 and the aluminum plate 200 are not too large, and therefore, the welding amount is not large in the welding process, and the welding is also more convenient.
Since the honeycomb core in the aluminum honeycomb 100 tends to be softer and thus does not exert a good bearing force at all, in order to achieve a good connection of the aluminum honeycomb 100 to the connection structure body 1, the upper plate 101 in the aluminum honeycomb 100 is usually lapped on the first lapping position 2, and then the upper plate 101 is fixedly connected to the first lapping position 2. Since the thickness of the upper sheet 101 tends to be thin, however, in particular, the thickness is generally preferably 2 mm, in this case, by additionally providing the support member 4 such that the support member 4 is provided on one side of the connection structure body 1 and extends in a direction away from the connection structure body 1, at the same time, the support member 4 is positioned below the first lapping position 2 for carrying the aluminum honeycomb 100, and thus, since the support member 4 and the lower surface of the aluminum honeycomb 100 are in contact with each other, the contact area therebetween is increased, a good support force for the aluminum honeycomb 100 in an upward direction can be provided, thereby effectively improving the connection strength between the aluminum honeycomb 100 and the first lap joint part 2 of the connecting structure body 1, avoiding the aluminum honeycomb 100 from being supported by self gravity under the condition of no stress, so that the connection portion between the aluminum honeycomb 100 and the first lap joint portion 2 is broken.
Therefore, the connecting structure of the application is also used as a bearing stress point, and therefore, stress parts such as partial cab lifting seats and the like can be welded to the bottom of the connecting structure, and are prevented from being directly welded to the aluminum honeycomb 100 and the aluminum plate 200, so that the bearing capacity is improved.
In addition, it should be noted that, by adding the connection structure, the longitudinal height difference between the first lap joint position 2 and the second lap joint position 3 is equal to the longitudinal thickness difference between the aluminum plate 200 and the aluminum honeycomb 100, so that the welding defects and deformation of the splice position between the aluminum honeycomb 100 and the aluminum plate 200 are effectively solved, and the reliability and the aesthetic property of the welding between the aluminum honeycomb 100 and the aluminum plate 200 are ensured.

One end of the aluminum plate 200 is lapped on the second welding position of the second shoulder 6 and is welded with the second shoulder 6 into a whole. Specifically, one end of the aluminum plate 200 is lapped on the second welding position of the second shoulder 6, so that the position arrangement between the aluminum plate 200 and the connecting structure body 1 is realized, and then the fixed connection between the connecting structure body 1 and the aluminum plate 200 is realized by adopting a welding mode.

Since the honeycomb core in the aluminum honeycomb 100 tends to be softer and thus does not exert a good bearing force at all, in order to achieve a good connection of the aluminum honeycomb 100 to the connection structure body 1, the upper plate 101 in the aluminum honeycomb 100 is usually lapped on the first lapping position 2, and then the upper plate 101 is fixedly connected to the first lapping position 2. Since the thickness of the upper sheet 101 tends to be thin, however, in particular, the thickness is generally preferably 2 mm, in this case, by additionally providing the support member 4 such that the support member 4 is provided on one side of the connection structure body 1 and extends in a direction away from the connection structure body 1, at the same time, the support member 4 is positioned below the first lapping position 2 for carrying the aluminum honeycomb 100, and thus, since the support member 4 and the lower surface of the aluminum honeycomb 100 are in contact with each other, the contact area therebetween is increased, a good support force for the aluminum honeycomb 100 in an upward direction can be provided, thereby effectively improving the connection strength between the aluminum honeycomb 100 and the first lap joint part 2 of the connecting structure body 1, avoiding the aluminum honeycomb 100 from being supported by self gravity under the condition of no stress, so that the connection portion between the aluminum honeycomb 100 and the first lap joint portion 2 is broken.
Therefore, the connecting structure of the application is also used as a bearing stress point, and therefore, part of stressed parts such as cab hangers and the like can be welded at the bottom of the connecting structure and are prevented from being directly welded on the aluminum honeycomb 100 and the aluminum plate 200, and the bearing capacity is improved.
In addition, it should be noted that, by adding the connection structure, and making the longitudinal height difference between the first lap joint position 2 and the second lap joint position 3 equal to the longitudinal thickness difference between the aluminum plate 200 and the aluminum honeycomb 100, the welding defect and deformation at the joint position between the aluminum honeycomb 100 and the aluminum plate 200 are effectively solved, and the reliability and the aesthetic property of the welding between the aluminum honeycomb 100 and the aluminum plate 200 are ensured.
It should be noted that the connection structure of the present application can be bent or deformed according to actual needs, so that the connection structure of the present application has better versatility, and is particularly suitable for connecting transitional connection positions of the aluminum honeycomb 100 and the aluminum plate 200.
