Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and in particular to a telescopic humanoid robot. Background Technology

[0002] Humanoid robots on the market today are machines with specific structures that can be controlled to move. Generally, robots consist of a body, arms, and a mobile chassis. The mobile chassis can drive the body to move. When moving, the robot can replace humans to do many jobs. In some areas with harsh and dangerous environments, robots can be used for exploration or related technological operations.

[0003] For example, in the prior art, Chinese patent authorization number CN217453942U, application date: 2022-06-30, entitled "A Humanoid Robot", includes a head mechanism, a body mechanism, two arm mechanisms, and two leg mechanisms. The body mechanism is located at the bottom of the head mechanism, the two arm mechanisms are respectively located on both sides of the body mechanism, and the two leg mechanisms are respectively located on the side of the body mechanism away from the head mechanism. The head mechanism provides the mounting conditions for the body mechanism, and the body mechanism provides the mounting conditions for the two arm mechanisms and the two leg mechanisms. The operation of the body mechanism can drive the head mechanism to rotate, and the drive mechanism can drive the two arm mechanisms to move up and down. The operation of the two leg mechanisms can drive the body mechanism to move, which improves the robot's flexibility and solves the problem of insufficient flexibility in the movement of existing robots.

[0004] However, the aforementioned patent still has shortcomings. When grasping goods, the simple robotic arm makes it easy for the goods to fall off due to the unstable grip, which further reduces the safety of the humanoid robot during operation.

[0005] Therefore, in order to address this problem, this utility model presents a telescopic humanoid robot. Utility Model Content

A telescopic mechanism is fixedly connected to the bottom of the arm assembly, and a gripping mechanism is fixedly connected to the end of the telescopic mechanism. The gripping mechanism includes a rotating frame rotatably connected to the surface of the telescopic mechanism via a drive unit.

[0013] Preferably, the guide grooves are arranged in two sets, and the two sets of guide grooves are arranged symmetrically on the left and right sides along the center line of the adjusting cylinder.

[0014] Preferably, a T-shaped slide is fixedly connected to the top of the rotating frame, and a clamping block is slidably connected to the surface of the T-shaped slide.

[0015] Compared with the prior art, this utility model provides a telescopic limb humanoid robot with the following beneficial effects:

[0016] This telescopic humanoid robot can adjust the distance of the gripping mechanism through its telescopic mechanism. Then, with the cooperation of the rotating frame, rotating plate, linkage rod and clamping block, it can grasp the goods.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0025] Reference Figures 1-5 A telescopic humanoid robot includes a body assembly 1. A leg assembly 2 is rotatably connected to the bottom of the body assembly 1 via a drive unit. An arm assembly 3 is rotatably connected to the side wall of the body assembly 1 via a drive unit. A telescopic mechanism 4 is fixedly connected to the bottom of the arm assembly 3. A gripping mechanism 5 is fixedly connected to the end of the telescopic mechanism 4. The gripping mechanism 5 includes a rotating frame 51 rotatably connected to the surface of the telescopic mechanism 4 via a drive unit. A rotating plate 52 is rotatably connected to the surface of the rotating frame 51 via a drive unit. A linkage rod 53 is rotatably connected to the surface of the rotating plate 52 via a rotating shaft. A clamping block 54 is rotatably connected to the end of the linkage rod 53 via a rotating shaft. The clamping block 54 slides above the rotating frame 51.

[0026] In this invention, during use, the driving part on the surface of the leg assembly 2 at the bottom of the body assembly 1 first operates, causing the body assembly 1 to move. The driving part on the surface of the arm assembly 3 operates, causing the telescopic mechanism 4 to adjust its angle. Then, the telescopic mechanism 4 drives the gripping mechanism 5 to extend and retract, thereby adjusting the distance of the gripping mechanism 5. The gripping mechanism 5 can better grasp goods for handling. The rotation of the driving part at the bottom of the rotating frame 51 changes the angle of the rotating frame 51, making it more flexible when grasping goods. The rotation of the driving part at the back of the rotating frame 51 causes the rotating plate 52 to rotate. The rotation of the rotating plate 52 can adjust the linkage rod 53, thereby adjusting the clamping block 54, thus completing the grasping of goods.

[0027] In addition, the drive unit is motor driven, and both the leg assembly 2 and the arm assembly 3 are configured in two sets.

[0028] Reference Figure 4 The telescopic mechanism 4 includes an adjusting cylinder 41. The inner top wall of the adjusting cylinder 41 is rotatably connected to a threaded rod 42 via a drive unit. The surface of the threaded rod 42 is threadedly connected to a telescopic cylinder 43. The telescopic cylinder 43 slides inside the adjusting cylinder 41 and extends outward.

[0029] In this invention, the internal drive unit of the adjusting cylinder 41 is activated to rotate the threaded rod 42. The rotation of the threaded rod 42 can displace the telescopic cylinder 43 on the surface, thereby adjusting the telescopic distance of the gripping mechanism 5, making gripping more flexible.

[0030] To clarify, the drive unit is an electric motor.

[0031] Reference Figure 4 The inside of the adjusting cylinder 41 is provided with a guide groove 44, and a limit block 45 is slidably connected inside the guide groove 44. The limit block 45 is fixed to the side wall of the telescopic cylinder 43.

[0032] In this invention, the guide groove 44 inside the adjusting cylinder 41 guides and limits the limiting block 45. Since the limiting block 45 is fixed on the surface of the telescopic cylinder 43, it ensures the stability of the telescopic cylinder 43 when it moves.

[0033] Reference Figure 5 The bottom of the adjusting cylinder 41 is connected to a mounting plate 46, which is mounted on the end of the arm assembly 3.

[0034] In this invention, the mounting plate 46 is designed to facilitate assembly and fixation with the bottom of the arm assembly 3.

[0035] Reference Figure 4 The surface of the mounting plate 46 has through holes, and the surface of the arm assembly 3 is connected to the inside of the through holes by bolts.

[0036] In this invention, through holes are provided on the surface of the mounting plate 46 to facilitate the through-hole connection of bolts to the surface of the arm assembly 3, enabling rapid installation and fixation.

[0037] Reference Figure 5 The guide grooves 44 are set in two sets, and the two sets of guide grooves 44 are symmetrically arranged on the left and right sides along the center line of the adjusting cylinder 41.

[0038] In this invention, with two sets of guide grooves 44, the guide grooves 44 can guide and limit the movement of the telescopic cylinder 43 on both sides, thereby ensuring the stability of the telescopic cylinder 43 during movement.

[0039] Reference Figure 2 A T-shaped slide block 55 is fixedly connected to the top of the rotating frame 51, and a clamping block 54 is slidably connected to the surface of the T-shaped slide block 55.

[0040] In this invention, the T-shaped slide 55 is configured to guide and limit the movement of the clamping block 54.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
