Description

Technical Field

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

[0002] With the development of automation and intelligent technologies, robots are widely used in various fields such as industry, service, and rescue, playing a vital role in replacing manual labor, improving operational efficiency, and ensuring personnel safety. In complex or high-risk environments, robots need to possess excellent terrain adaptability, especially when performing vertical movement operations in multi-story buildings, narrow passages, or areas without elevators, where traditional wheeled or tracked mobility methods are often limited. To meet the application needs in these scenarios, robots with stair-climbing capabilities are gradually gaining attention. They can be widely used in fire rescue, security patrols, express delivery, cleaning services, and other situations, improving operational flexibility and responsiveness.

[0003] Existing stair-climbing robots possess a certain climbing capability in terms of structure and drive mechanism. Common technical solutions include tracked, legged, and hybrid wheel-legged structures. Tracked robots rely on continuous tracks to maintain contact with the ground, thereby traversing stair steps; legged robots use bionic joint drives to adjust gait, adapting to different step heights and angles; hybrid wheel-legged structures combine the speed advantage of wheeled travel with the terrain adaptability of legged structures, improving the robot's traversal in diverse stair environments. However, existing stair-climbing robots still have certain limitations, particularly in terms of equipment stability and motion synchronization. In actual climbing processes, the robot often exhibits uncoordinated movements due to dispersed drive structures, resulting in problems such as swaying and slipping. Therefore, the stair-climbing robot is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a stair-climbing robot, which aims to improve the problems of uncoordinated movements and swaying and slipping during climbing caused by the dispersed drive structure in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stair-climbing robot includes a base, a storage mechanism on the top of the base, and a climbing mechanism on the side wall of the base.

[0007] The climbing mechanism includes a climbing plate. The base has a cavity inside and a dual-head motor is installed inside. The output end of the dual-head motor passes through the side wall of the base and extends to the outside. The output end of the dual-head motor is fixedly connected to a rotating plate. A connecting shaft is rotatably connected inside the rotating plate. The climbing plate is fixedly connected to the side wall of the connecting shaft. Both the base and the climbing plate have a first slot and a second slot inside. A cover plate is provided on the top of the base. The side wall of the cover plate is slidably connected to the top of the cavity.

[0008] As a further description of the above technical solution:

[0009] Both the ramp and the base are fixedly connected with anti-slip strips, which are located inside the slots.

[0010] As a further description of the above technical solution:

[0011] The base is fixedly connected to the bottom of the base with a second anti-slip strip, and the base is fixedly connected to the side wall with a baffle.

[0012] As a further description of the above technical solution:

[0013] The storage mechanism includes a storage box and a lid. The storage box is fixedly connected to the top of the base, and the lid is connected to the storage box via a hinge.

[0014] As a further description of the above technical solution:

[0015] A fixing block is fixedly connected to the side wall of the storage box, and a connecting block is fixedly connected to the side wall of the box lid.

[0016] As a further description of the above technical solution:

[0017] A clamping plate is fixedly connected to the side wall of the fixing block, and the top of the clamping plate is protruding.

[0018] As a further description of the above technical solution:

[0019] The connecting block is rotatably connected to a rotating frame, and the side wall of the rotating frame is fixedly connected to a slot plate. The slot plate has a groove inside, and the slot plate engages with the slot plate.

[0020] As a further description of the above technical solution:

[0021] A spring is fixedly connected between the connecting block and the slot plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the double-sided rotating plates are driven by the starting motor to rotate, so that the climbing plates move synchronously and abut against the corner of the step, thereby achieving support and flipping propulsion of the equipment. The base moves up gradually during rotation, and the continuous rotation of the rotating plates can achieve the effect of continuous stair climbing. Through the cooperation between the above structures, the stability and synchronization of the equipment during the stair climbing process are improved.

[0024] 2. In this utility model, an object is placed inside the storage box, and then the box lid is closed. At this time, the slot plate will be guided by the protrusion of the slot plate and deflected inside the connecting block by the rotating frame, and the spring will be stretched to deform it. When the groove inside the slot plate is aligned with the protrusion of the slot plate, the spring will drive the slot plate to reset and engage with the slot plate, ensuring that the box is closed firmly and preventing the object in the storage box from falling off during the equipment climbing the stairs.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a stair-climbing robot, including a base 1. A storage mechanism is provided on the top of the base 1 for effectively storing and transporting objects during operation. A climbing mechanism is provided on the side wall of the base 1 to enable the robot to climb stairs. The climbing mechanism includes a ramp 6, providing the inclined support required for the robot to ascend and descend stairs. A cavity 2 is provided inside the base 1, and a dual-head motor 3 is installed inside. The output ends of the dual-head motor 3 penetrate through the side wall of the base 1 and extend to the outside, simultaneously driving the transmission structures on both sides, improving the stability and synchronization of the device. A rotating plate 4 is fixedly connected to the output ends of both dual-head motor 3. The rotation of the rotating plate 4 drives subsequent components to perform climbing actions. A connecting shaft 5 is rotatably connected inside the rotating plate 4, connecting... A ramp 6 is fixedly connected to the side wall of shaft 5. The ramp 6 is further deflected by the rotation of the rotating plate 4. Both the base 1 and the ramp 6 have slot 1 7 and slot 2 8. The top of the base 1 is provided with a cover plate 11. The side wall of the cover plate 11 is slidably connected to the top of the cavity 2, which effectively prevents dust, water vapor and other factors from affecting the dual-head motor 3. Both the ramp 6 and the base 1 have anti-slip strip 1 9 fixedly connected to the inside. The anti-slip strip 1 9 is set inside the slot 1 7. The bottom of the base 1 has anti-slip strip 2 10 fixedly connected to the bottom. This can effectively increase the friction with the ground when the robot is working, prevent slipping and enhance safety. The side wall of the base 1 is fixedly connected with a baffle 12, which provides protection on the front and rear sides and prevents the equipment from being damaged by impact.

[0033] Reference Figure 1 and Figure 4 The storage mechanism includes a storage box 13 and a lid 14. The storage box 13 is fixedly connected to the top of the base 1 for easy storage of transported objects. The lid 14 is connected to the storage box 13 via a hinge, allowing the lid 14 to open and close smoothly. A fixing block 15 is fixedly connected to the side wall of the storage box 13, and a connecting block 17 is fixedly connected to the side wall of the lid 14. A retaining plate 16 is fixedly connected to the side wall of the fixing block 15. The top of the retaining plate 16 is convex and has a certain tilt angle. A rotating frame 18 is rotatably connected inside the connecting block 17. A retaining plate 19 is fixedly connected to the side wall of the rotating frame 18. The retaining plate 19 can be deflected on the connecting block 17 by the rotating frame 18. The slot plate 19 has a groove inside, which matches the protrusion on the top of the card plate 16. When the card plate 19 moves downward, it will deflect along the inclined surface of the protrusion on the top of the card plate 16, and the card plate 19 will engage with the card plate 16. A spring 20 is fixedly connected between the connecting block 17 and the card plate 19. When the card plate 19 deflects, it will stretch the spring 20. When the groove inside the card plate 19 moves outside the protrusion of the card plate 16, the spring 20 loses pressure and drives the card plate 19 to reset, so that it engages with the card plate 16, ensuring the firmness of the box closure and preventing objects in the storage box 13 from falling during the equipment climbing the stairs.

[0034] Working principle: When using this device, objects can be placed inside the storage box 13, and then the box lid 14 is closed. As the box lid 14 flips downward, the slot plate 19, guided by the protrusion of the slot plate 16, deflects inside the connecting block 17 via the rotating frame 18, stretching the spring 20 to deform it. When the groove inside the slot plate 19 moves outside the protrusion of the slot plate 16, the spring 20 loses pressure and drives the slot plate 19 to reset, making it engage with the slot plate 16, ensuring the firmness of the box closure. Then, the dual-head motor 3 is started to drive the rotating plates 4 on both sides to rotate simultaneously. With the linkage of the ramp plate 6, the front rotating plate 4 moves synchronously, and the ramp plate 6 is engaged on the step through the slot 7. At this time, the ramp plate 6 will support the device, and as the rotating plate 4 continues to rotate, the base 1 will continue to flip forward. Then, the slot 7 at the bottom of the base 1 abuts against the corner of the step. Repeating the above steps can achieve the effect of gradually climbing stairs.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
