Description

TECHNICAL FIELD

[0001] The present application relates to the field of robots, and in particular to a robot mechanical arm. BACKGROUND

[0002] Since elevators installed in various buildings can come from different manufacturers, the overall layout of the inside and outside buttons of elevators from different manufacturers is high or low, so the mechanical arm of the autonomous elevator robot needs to have a very large operating range and be height-adjustable to adapt to elevators in different scenarios. At present, most robot mechanical arms on the market can only be fixedly installed on the robot and cannot be adjusted in height by stretching up and down, and cannot adapt to elevators in different scenarios. Even if some robot mechanical arms can adjust the height by means of electrically controlled stretching, the structure is relatively complex, occupies a large space, and the stretched-out part is exposed and has safety hazards. SUMMARY

[0003] In view of one or more of the above problems, a robot mechanical arm according to an embodiment of the present application is provided.

[0004] The robot mechanical arm according to an embodiment of the present application comprises a telescopic outer pipe seat, a telescopic inner pipe seat, and a mechanical arm body, wherein: the telescopic outer pipe seat is used to fix the robot mechanical arm to the robot; the telescopic inner pipe seat is arranged inside the telescopic outer pipe seat and connected to the telescopic outer pipe seat in a telescopic sliding manner relative to the telescopic outer pipe seat; and the mechanical arm body is connected to the telescopic inner pipe seat.

[0005] In some embodiments, the telescopic outer pipe seat is composed of a first telescopic sleeve with a flange. The first end of the telescopic outer pipe seat is provided with one or more welded nuts, which are used to cooperate with the jam nuts to jam the telescopic outer pipe seat and the telescopic inner pipe seat. The second end of the telescopic outer pipe seat is provided with a flange, which is used to fix the telescopic outer pipe seat to the robot.

[0006] In some embodiments, the telescopic inner pipe seat is composed of a second telescopic sleeve with a flange and can freely slide up and down relative to the telescopic outer pipe seat. The telescopic inner pipe seat is provided with one or more coupling structures, the positions of which correspond to the welded nuts on the telescopic outer pipe seat. One end of the telescopic inner pipe seat is provided with a flange, which is used to fix the mechanical arm body to the telescopic inner pipe seat.

[0007] In some embodiments, the robot mechanical arm further comprises a telescopic protective sleeve, which is arranged outside the telescopic outer pipe seat and can be elongated to a length that is adapted to the length of the telescopic inner pipe seat exposed outside the telescopic outer pipe seat when the telescopic inner pipe seat is stretched out from inside the telescopic outer pipe seat. The telescopic protective sleeve is one or more telescopic sleeve assemblies combined together, or a telescopic integrated protective sleeve. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 A structural schematic diagram of a robot arm according to an embodiment of the present application is shown. As Figure 1 shown, the robot arm 100 according to an embodiment of the present application includes a telescopic outer pipe base 102, a telescopic inner pipe base 104, and a robot arm body 106, wherein: the telescopic outer pipe base 102 is used to fix the robot arm 100 to the robot 200; the telescopic inner pipe base 104 is arranged inside the telescopic outer pipe base 102 and is connected to the telescopic outer pipe base 102 in a telescopic sliding manner relative to the telescopic outer pipe base 102; and the robot arm body 106 is connected to the telescopic inner pipe base 104.

[0012] As Figure 1As shown, in some embodiments, the telescopic outer tube seat 102 is composed of a first telescopic sleeve with a flange, wherein: the first end of the telescopic outer tube seat 102 is provided with one or more welded nuts, which are used to cooperate with the tightening screw 108 to tighten the telescopic outer tube seat 102 and the telescopic inner tube seat 104 to achieve a fixed effect; the second end of the telescopic outer tube seat 102 is provided with a flange, which is used to cooperate with the screw to fix the telescopic outer tube seat 102 to the robot 200.

The telescopic inner tube seat 104 is provided with one or more openings, slots, or other coupling structures. The positions of these coupling structures correspond to the welded nuts on the telescopic outer tube seat 104. The tightening screw 108 tightens the telescopic inner tube seat 104 and the telescopic outer tube seat 102 through the coupling structure on the telescopic inner tube seat 104, thereby fixing them. One end of the telescopic inner tube seat 104 is provided with a flange, which is used to cooperate with the screw to fix the robotic arm body 106 to the telescopic inner tube seat 104.

Here, when the retractable protective sleeve 106 extends to a length adapted to the length of the telescopic inner tube seat 104 exposed outside the telescopic outer tube seat 102, the telescopic inner tube seat 102 can be hidden inside it, thereby protecting the telescopic inner tube seat 102.

[0015] like Figure 1 As shown, in some embodiments, when the robotic arm 100 is fixed to the robot 200, the retractable protective sleeve 106 is fixed to the robot 200. However, those skilled in the art will understand that, depending on actual needs, the retractable protective sleeve 105 can also be fixed together with the retractable outer tube seat 104.

[0016] like Figure 1 As shown, in some embodiments, the retractable protective sleeve 106 is a retractable sleeve assembly consisting of one or more sections combined together, or it can be a retractable integral protective sleeve or other types of sleeve.
