Description
Technical Field
[0001] The present application relates to the technical field of service robot protection, and in particular to a service robot capable of collision protection. Background Art
[0002] A service robot is a robot that can provide various services to humans in a non-industrial environment. It integrates multiple technologies such as mechanics, electronics, computers, and sensors, and has the ability to perceive the environment and perform tasks. The application scenarios of service robots are very wide. In family scenarios, they can take on housework. For example, a sweeping robot can automatically clean dust and debris on the ground, reducing people's housework burden; there are also intelligent companion robots that can interact with family members, chat with the elderly, tell stories to children, and bring fun and emotional companionship to the family. In the commercial field, service robots can provide guidance services in hotels, leading guests to rooms, restaurants and other places; in restaurants, they can complete food delivery tasks and accurately deliver dishes to customers' tables. In medical environments, service robots can assist medical staff in transporting medicines and medical equipment, and even play an auxiliary role in some simple nursing work, providing efficient, convenient and intelligent services for human life and work.
[0003] Currently, existing service robots usually lack corresponding anti-collision buffer structures on the outside during use. During use, the outside of the service robot is very likely to collide with objects, causing the service robot to be damaged by collision. Even if some service robots are equipped with spring buffer mechanisms, their buffer structures are usually not convenient to adjust according to the overall longitudinal height of the robot during use. The overall protection range is small and cannot be adjusted. It can be seen that the service robots have certain defects and shortcomings as a whole, and therefore need to be improved.
[0004] Currently, the existing service robots have some obvious defects and shortcomings during actual application. Usually, the outside of the service robot lacks the corresponding anti-collision buffer structure. During use, since the service robot needs to move and perform tasks in various environments, its outer side is very likely to collide with surrounding objects. Once a collision occurs, the service robot is likely to be damaged by the collision, which will not only affect the normal use of the service robot, but also increase maintenance costs. Although some service robots are equipped with a spring buffer mechanism, in actual use, this buffer structure is usually not convenient to adjust according to the overall longitudinal height of the robot, which results in a small overall protection range and cannot be adjusted, making it difficult to adapt to different usage scenarios and collision situations. It can be seen that the existing service robots have certain defects and shortcomings in terms of anti-collision buffering as a whole, and there is an urgent need to improve them to improve the durability and reliability of the service robots and better meet the needs of various application scenarios.

[0029] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will provide a clear and complete description of the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.
[0030] Example
[0031] refer to Figures 1 to 5 A service robot capable of collision protection in this embodiment includes: a robot base 100, both sides of the robot base 100 are rotatably connected to a fixed frame 200, the interior of the fixed frame 200 is rotatably connected to a moving crawler 300, a mounting seat 400 is fixedly installed on the top of the robot base 100, mounting grooves 500 are evenly spaced on the outside of the mounting seat 400, a buffer mechanism 600 is fixedly connected to the inside of the mounting groove 500, the buffer mechanism 600 is sleeved on the outside of the mounting seat 400, and mounting holes 700 are evenly spaced and arranged in a ring on the top of the mounting seat 400.
[0032] The buffer mechanism 600 includes an anti-collision spring 610, which is fixedly installed inside the mounting groove 500. The outer end of the anti-collision spring 610 is fixedly installed with an anti-collision lower ring 620. The top of the anti-collision lower ring 620 is fixedly connected to a telescopic component 630. The top of the telescopic component 630 is fixedly installed with an adjustment component 650. The upper end of the telescopic component 630 is provided with an elastic component 660 on the side close to the adjustment component 650. The fixed frame 200 and the moving track 300 on both sides of the robot base 100 ensure the stable movement of the robot. The buffer mechanism 600 outside the mounting seat 400 provides effective protection for the robot. The anti-collision spring 610 in the mounting groove 500 can play a buffering role when the robot is hit, reducing the damage to the robot caused by the impact force.
[0033] The anti-collision lower ring 620, in conjunction with the telescopic assembly 630, the adjustment assembly 650, and the elastic assembly 660, allows for flexible adjustment of the protection range to suit different scenarios. Furthermore, it provides comprehensive protection in the event of a collision, cushioning the impact regardless of direction. This overall structure enhances the service robot's durability and stability, ensuring reliable operation in a variety of complex environments.
[0034] Guide frames 640 are fixedly connected to the upper and lower ends of the outer side of the mounting base 400. Support plates 670 are fixedly connected to the top and bottom of the anti-collision lower ring 620 in a circular arrangement. Anti-slip grooves are evenly spaced on the outer concave surface of the movable track 300. The outer sides of the support plates 670 are closely connected to the guide frames 640. The guide frames 640 at the upper and lower ends of the outer side of the mounting base 400 cooperate with the support plates 670 fixed to the top and bottom of the anti-collision lower ring 620 in a circular arrangement. During operation of the robot, the outer sides of the support plates 670 are closely connected to the guide frames 640, providing stable guidance for the movement of the anti-collision lower ring 620, ensuring that the anti-collision lower ring 620 moves in the correct direction when buffering against collisions, avoiding deviation or instability, thereby improving the reliability and effectiveness of the buffer mechanism 600. At the same time, the anti-skid grooves opened at equal intervals on the outer concave surface of the mobile track 300 can increase the friction between the robot and the ground, improve the stability and safety of the robot's movement, prevent slipping during operation, and further ensure the normal operation and work efficiency of the service robot.
[0035] The telescopic assembly 630 includes vertical rails 631, which are arranged in a ring with equal spacing and fixedly connected to the outside of the anti-collision lower ring 620. A slide 632 is slidably connected to the inside of the vertical rails 631, and the top of the slide 632 is fixedly connected to the anti-collision upper ring 633. The elastic assembly 660 and the adjustment assembly 650 are mounted on one side of the anti-collision upper ring 633. The adjustment assembly 650 includes a screw rod 651 and a connecting bracket 652. The connecting bracket 652 is fixedly connected to the top side of the anti-collision lower ring 620. The screw rod 651 is rotatably connected to the bottom side of the anti-collision upper ring 633, and the screw rod 651 and the connecting bracket 652 are threadedly connected. The top of the screw rod 651 passes through the anti-collision upper ring 633 and is fixedly connected to the adjustment handle 653. The vertical rails 631 are arranged in a ring and fixed to the outside of the anti-collision lower ring 620, providing a stable sliding track for the slide 632. The slide plate 632 slides within the vertical rail 631, connecting the bottom anti-collision lower ring 620 and the top anti-collision upper ring 633, so that the distance between the two can be flexibly adjusted. By cooperating with the screw rod 651 and the connecting frame 652 in the adjustment component 650, rotating the adjustment handle 653 can drive the screw rod 651 to rotate. Since the screw rod 651 is threadedly connected to the connecting frame 652, the anti-collision upper ring 633 can be moved up and down, and the protection height and range can be flexibly adjusted according to different needs. This design improves the adaptability and flexibility of the protection mechanism, can better cope with various collision situations, and provide more effective protection for the service robot.
[0036] The elastic component 660 includes a concave frame 661 and a top plate 662. The concave frame 661 is fixedly connected to the bottom of the anti-collision upper ring 633 near the side of the screw rod 651. The inside of the concave frame 661 is fixedly connected to the limit spring 663, and the top of the limit spring 663 is fixedly connected to the limit pin 664. The top plate 662 is fixedly connected to the bottom of the adjusting handle 653. Limiting holes 665 are arranged at equal intervals on the outside of the top plate 662. The end of the limiting pin 664 passes through the anti-collision top ring and is inserted into the inside of the limiting hole 665. The bottom of the limiting pin 664 is fixedly connected to the connecting shaft 666. The bottom of the connecting shaft 666 passes through the concave frame 661 and is fixedly connected to the pull ring 667. The concave frame 661 is fixed to the bottom of the anti-collision upper ring 633, providing a stable installation position for the limiting spring 663. Limiting spring 663 is connected to limiting pin 664. Once the position of anti-collision upper ring 633 is adjusted, limiting spring 663 can push limiting pin 664 into limiting hole 665 on the outside of top plate 662, thereby securing the position of adjustment handle 653 and anti-collision upper ring 633. This ensures that the protection height and range will not accidentally change during use, thereby improving the stability of the protection mechanism. When adjustment is needed, the pull ring 667 pulls the connecting shaft 666 to disengage limiting pin 664 from limiting hole 665, allowing the adjustment handle 653 to be easily operated again. This design is simple and convenient to operate, enhances the flexibility and adjustability of the protection mechanism, and can better adapt to different working scenarios and collision situations, providing reliable protection for the service robot.
[0037] The principle of use and its advantages are as follows: during the movement of the robot base 100, once it is hit, the anti-collision upper ring 633 and the anti-collision lower ring 620 can promptly assist in contact buffering. When impacted, the anti-collision spring 610 on the inner side of the anti-collision upper ring 633 and the anti-collision lower ring 620 can play an important role in assisting in telescopic buffering. During the buffering process, the guide frame 640 and the support plate 670 fit together or slide with each other, which can assist in guiding the anti-collision lower ring 620 and enable it to buffer stably. During the overall use, the setting of the anti-collision lower ring 620 is of great significance and can stably form 360-degree comprehensive buffering. Regardless of the direction in which the robot base 100 moves, it can assist in buffering and shock resistance, greatly improving the buffering and protection performance of the device during overall use.
[0038] The rotation of the adjustment handle 653 can assist in driving the screw rod 651 located at the bottom of the anti-collision upper ring 633 to rotate. At this time, the screw rod 651 and the connecting frame 652 are threadedly connected to each other, and can reversely resist and drive the slide plate 632 inside the vertical rail 631 to slide upward. The upward movement of the slide plate 632 can drive the displacement of the anti-collision upper ring 633, and the displacement of the anti-collision upper ring 633 can assist in flexibly adjusting the reciprocating displacement of the anti-collision upper ring 633 and the anti-collision lower ring 620. In this way, the spacing between the anti-collision upper ring 633 and the anti-collision lower ring 620 can be flexibly adjusted. During use, the overall protective coverage area of the anti-collision upper ring 633 and the anti-collision lower ring 620 can be flexibly adjusted according to actual needs, thereby achieving better protective performance. During the adjustment process, the limit spring 663 can be reset to drive the limit pin 664 to move upward and insert into the inner side of the limit hole 665. When the limiting pin 664 is inserted into the limiting hole 665 , the top plate 662 can be fixed. Once the top plate 662 is fixed, the adjusting handle 653 can be stably fixed, thereby improving its overall stability.
[0039] Furthermore, during use, if adjustment is required, the connecting shaft 666 can be driven downward by pulling the pull ring 667. The downward movement of the connecting shaft 666 can then pull the limit pin 664 downward. When the limit pin 664 moves downward, it can disengage from the limit hole 665. At this point, the limit pin 664 and the limit hole 665 are separated, and the adjustment knob handle can be rotated again, thereby stably adjusting the entire buffer mechanism 600 for telescopic displacement. After the protection range is adjusted, the limit spring 663 is reset to push the limit pin 664 into the interior of the limit hole 665. The limit pin 664 and the limit hole 665 engage with each other to limit their positions, allowing for quick and stable positioning after adjustment. This greatly improves the overall convenience and stability of the device, bringing great convenience to the use of the device.
