Meanwhile, in order to prevent the difficulty in manufacturing due to the excessively large layout area of the hollow support structure 5 and the easy deformation of the hollow support structure 5, the form of connecting the reinforcing ribs 3 with the hollow support structure 5 is adopted to reduce the continuity of the hollow support structure 5, thereby reducing the difficulty in manufacturing, and simultaneously preventing the problem that the layout area of the hollow support structure 5 is excessively large and is difficult to connect. And because the reinforcing ribs 3 are fixedly connected with the inside of the shell casing 1, the reinforcing ribs 3 can also improve the supporting effect of the shell casing 1.

Compared with the prior art, the mechanical arm joint shell can more comprehensively increase the hardness of the shell through the combination of the reinforcing ribs 3 and the hollow supporting structures 5, and the increased weight and the consumed materials are less compared with the mode of thickening the wall shell, so that the mechanical arm joint shell can comprehensively improve the hardness and reduce the increased weight and the consumed materials.

Please refer to fig. 2, which is a structural diagram of a hollow supporting structure 5 according to an embodiment of the present invention. In one possible embodiment, the supporting column 51 is a hexagonal hollow column formed by six supporting plates connected in sequence and surrounded, and the six supporting plates are perpendicular to the inner wall of the housing shell 1.

In the present embodiment, since the supporting columns 51 are hexagonal prism hollow columns, the hollow supporting structure 5 is a honeycomb structure, and since the honeycomb structure is a hexagonal socket, external forces from all directions can be dispersed and borne, so that the resistance of the honeycomb structure to the extrusion force is much higher than that of any round or square shape. Therefore, the hexagonal-prism hollow column surrounded by the support plate perpendicular to the inner wall of the housing case 1 can enhance the supporting effect on the housing case 1.

In a possible embodiment, the housing shell 1 includes a first shell 11 and a second shell 13 which are mirror-symmetrical, and the first shell 11 and the second shell 13 are spliced to form the housing shell 1; the reinforcing ribs 3 comprise first reinforcing ribs and second reinforcing ribs; the first reinforcing ribs are arranged on the inner wall of the first shell 11, and the second reinforcing ribs are arranged on the inner wall of the second shell 13; the first reinforcing ribs on the inner wall of the first shell 11 and the second reinforcing ribs on the inner wall of the second shell 13 are in mirror symmetry.

In this embodiment, when the first shell 11 and the second shell 13 are spliced to form the shell housing 1, because the first reinforcing rib and the second reinforcing rib are mirror-symmetrical, the first reinforcing rib on the inner wall of the first shell 11 and the second reinforcing rib on the inner wall of the second shell 13 can be better butted, so that the reinforcing ribs 3 can better disperse and bear stress, thereby improving the effect of supporting the shell housing 1.

In a possible embodiment, the support columns include a first support column and a second support column, a plurality of the first support columns are disposed between adjacent first reinforcing ribs of the first housing 11, a plurality of the second support columns are disposed between adjacent second reinforcing ribs of the second housing 13, and the first support columns and the second support columns are in mirror symmetry.

The first shell 11 and the second shell 13 are spliced into the shell 1 through the clamping part and the clamping piece by a user conveniently.

In a possible embodiment, the housing shell 1 comprises a straight cylinder part and a turning part, and at least one reinforcing rib 3 is arranged between the inner wall of the straight cylinder part and the inner wall of the turning part.

In this embodiment, since the extending directions of the straight tube part and the turning part are different, if the straight tube part and the hollow supporting structure 5 on the inner wall of the turning part are directly connected, a misalignment easily occurs or a change in the shape of the hollow supporting structure 5 at the connection of the straight tube part and the turning part is caused, resulting in a poor effect of dispersing the born external force at the connection of the straight tube part and the turning part. The reinforcing ribs 3 are arranged at the joints of the straight cylinder parts and the turning parts, so that the hardness of the joints of the straight cylinder parts and the turning parts is improved, the stress effect of the joints of the straight cylinder parts and the turning parts is improved, the hollow supporting structures 5 are prevented from being connected in a staggered mode, the shape of the hollow supporting structures 5 can be prevented from being changed, and the effect of maintaining the hollow supporting structures 5 to bear external force in a dispersed mode is facilitated.

In a possible embodiment, the thickness of the support plate is less than the thickness of the reinforcing bars 3. Since the honeycomb structure is much more resistant to the pressing force than any of the circular or square shapes, the hollow support structure 5 can have a sufficient supporting effect even if the thickness of the support plate is smaller than that of the reinforcing ribs 3, and at the same time, it is advantageous to reduce the weight of the support plate.

In a possible embodiment, the inner wall of said first shell 11 is provided with at least 3 first reinforcing ribs and 4 groups of said hollow supporting structures 5; and at least 3 second reinforcing ribs and 4 groups of hollow supporting structures 5 are arranged on the inner wall of the second shell 13.
