Description

Technical Field

[0001] The utility model relates to the technical field of robot bases, in particular to an impact-resistant robot base. Background Technique

[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. Robots can execute tasks such as operations or movements through programming and automatic control. Robots have basic characteristics such as perception, decision-making, and execution. They can assist or even replace humans in performing dangerous, heavy, and complex tasks, improve work efficiency and quality, serve human life, expand or extend the scope of human activities and capabilities. Generally, robots need to be installed with a matching base.

[0003] For example, an impact-resistant robot with the publication number CN219504818U includes a robot base body. The robot base body includes a fixed seat. A slot is opened on the fixed seat. A buffer plate is movably installed inside the slot. A movable seat is movably installed inside the fixed seat. A support column is welded to the top of the movable seat. An installation plate is welded to the top of the support column. A robot is installed on the installation plate. The robot is installed inside an installation hole through bolts. A limit bolt is movably installed on the fixed seat. The limit bolt is connected to the movable seat. For this impact-resistant robot base, the movable seat realizes up and down buffering and shock absorption through shock absorbers and shock springs on the movable block, effectively avoiding damage to the robot caused by the impact force from the top. In addition, the cooperation of the limit bolt and the opening can realize the adjustment of the overall height of the movable seat.

[0004] The above patent can effectively avoid damage to the robot caused by impact. However, when being impacted by an external force, due to the impact, the overall center of gravity of the robot will shift. At this time, the robot is very likely to fall due to the external force. Generally, when the robot falls due to impact, it needs to be righted by manpower, and when the robot falls due to impact, it may also be damaged.

[0005] Therefore, we propose an impact-resistant robot base to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide an impact-resistant robot base to solve the problem raised in the above background technique that when being impacted by an external force, due to the impact, the overall center of gravity of the robot will shift. At this time, the robot is very likely to fall due to the external force. Generally, when the robot falls due to impact, it needs to be righted by manpower, and when the robot falls due to impact, it may also be damaged.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an impact-resistant robot base, comprising a hemispherical counterweight block and a fixed cover threadedly connected to the upper end of the hemispherical counterweight block, a mounting ring is fixedly installed on the outer side of the hemispherical counterweight block, mounting holes are opened around the mounting ring, support components are installed in the mounting holes, and a mounting seat is fixedly installed in the hemispherical counterweight block.

[0008] Preferably, the support assembly includes a fixing rod fixedly installed in the mounting hole, and a movable groove is formed inside the fixing rod.

[0009] Preferably, a bellows is fixedly mounted on the lower end of the fixing rod, a connecting rod is fixedly mounted on the lower end of the bellows, and a spring is fixedly mounted between the upper wall of the connecting rod and the lower wall of the fixing rod.

[0010] Preferably, a sliding groove is provided on the side wall of the connecting rod, and a movable rod is movably mounted on the lower end of the connecting rod.

[0011] Preferably, balls are fixedly mounted on both ends of the movable rod, and the two balls are slidably connected in the sliding groove.

[0012] Preferably, a roller is rotatably mounted on the movable rod, and limiting rings are fixedly mounted on both sides of the movable rod, and the limiting rings are respectively mounted on both sides of the roller.

[0013] Preferably, a vertical rod is fixedly mounted on the upper end of each of the connecting rods, and the vertical rod can be slidably mounted in the movable groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The hemispherical counterweight is a tumbler structure, and its principle is mainly based on the center of gravity being lower than the fulcrum, and the balance is maintained by the movement of the center of gravity. Specifically, there is a center of gravity inside the tumbler, and the appearance is usually designed as a cylinder with a wider bottom and a narrower top. When the tumbler is pushed over, the center of gravity will move, but it will always remain below the fulcrum. When the device as a whole is tilted or even topples over by external force, it can automatically restore to a vertical state under the action of the tumbler structure without the need for manual straightening.

[0016] 2. With the cooperation between the fixed rod, movable groove, bellows, connecting rod, slide groove, movable rod, limit ring, ball, roller, vertical rod and spring, when the device is tilted by external force, the cooperation between the above multiple components can quickly return to its original position, and the setting of the roller can also facilitate the movement of the entire device.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figure 1 - Figure 4 , an impact-resistant robot base, including a hemispherical counterweight 1 and a fixed cover 11 threadedly connected to the upper end of the hemispherical counterweight 1. An installation ring 2 is fixedly installed on the outer side of the hemispherical counterweight 1. Installation holes 21 are formed around the installation ring 2, and support assemblies 3 are installed in the installation holes 21. A mounting seat 12 is fixedly installed in the hemispherical counterweight 1.

[0024] In this embodiment: The robot can be fixedly installed on the upper end of the hemispherical counterweight 1 through the mounting seat 12, and the fixed cover 11 provides a protective effect on the robot. When the device is impacted, under the action of an external force, the whole device will tilt along the direction of the external force. The hemispherical counterweight 1 is in the structure of a tumbler, and its principle is mainly based on the center of gravity being lower than the fulcrum, and the balance is maintained by the movement of the center of gravity. Specifically, there is a center of gravity inside the tumbler, and its outer shape is usually designed as a cylindrical shape with a wider bottom and a narrower top. When the tumbler is pushed over, the center of gravity will move, but it always remains below the fulcrum (i.e., the point where the tumbler contacts the ground), so it can automatically return to the vertical state and maintain balance. Therefore, when the whole device is impacted by an external force and tilts or even topples, it can automatically return to the vertical state under the action of the tumbler structure without manual righting.

[0025] Embodiment 2: This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figure 2 - Figure 3 , the support assembly 3 includes a fixed rod 31 fixedly installed in the mounting hole 21, and an activity groove 311 is formed inside the fixed rod 31.

[0026] A bellows 32 is fixedly installed at the lower end of the fixed rod 31, a connecting rod 33 is fixedly installed at the lower end of the bellows 32, and a spring 37 is fixedly installed between the upper wall of the connecting rod 33 and the lower wall of the fixed rod 31. The spring 37 can push the bellows 32 outwards again after it shrinks and restore it to its original state.

[0027] A chute 331 is formed in the side wall of the connecting rod 33, and a movable rod 34 is movably installed at the lower end of the connecting rod 33.

[0028] Both ends of the movable rod 34 are fixedly installed with balls 342, and both balls 342 are slidably connected in the chute 331. The movable rod 34 can rotate along the chute 331 through the balls 342.

[0029] A roller 35 is rotatably installed on the movable rod 34, and limiting rings 341 are fixedly installed on both sides of the movable rod 34, and the limiting rings 341 are respectively installed on both sides of the roller 35. The limiting rings 341 can keep the roller 35 always in the middle position of the movable rod 34.

[0030] Vertical rods 36 are fixedly installed at the upper ends of the connecting rods 33, and the vertical rods 36 can be slidably installed in the activity groove 311. The vertical rods 36 can prevent the bellows 32 at the lower end from being bent greatly under the action of external force, resulting in its inability to reset.

[0031] In this embodiment: When the whole device is impacted by an external force, the device will deflect. At this time, the hemispherical counterweight 1 will tilt. When the hemispherical counterweight 1 tilts, the fixed rod 31 in the tilting direction is forced to move downward. At this time, the bellows 32 at the lower end shrinks. Since the roller 35 is always in contact with the ground, at this time, the vertical rod 36 slides into the inside of the activity groove 311. Since the impact of the external force is generated instantaneously and disappears directly, at this time, under the action of the hemispherical counterweight 1, the whole device can be gradually straightened back to the initial state. At the same time when the external force disappears, the spring 37 will also push the upper fixed rod 31 upward. Through the setting of the vertical rod 36, when the bellows 32 is shortened by an external force, it can be pushed outwards again and restored to its original shape. The lower ends of the roller 35 and the hemispherical counterweight 1 are both on the same plane, and when it needs to be moved, the device can be pushed to move, which is more convenient for moving the whole device.

[0032] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
