Description

Technical Field

[0001] This utility model belongs to the field of spherical robot technology and relates to a self-rolling reconnaissance ball for urban street fighting. Background Technology

[0002] With the widespread adoption of modern urbanization, urban warfare has become one of the most important forms of combat in modern and future warfare. Cities contain numerous high-rise buildings, narrow streets, and underground passages. In such environments, visibility is easily obstructed, and there are numerous blind spots for observation and firing. For example, at street corners, it is difficult to predict the enemy's personnel deployment and firepower. When clearing (confronting) the enemy in buildings, searches are often conducted floor by floor, making it difficult to predict whether enemies are lurking behind obstacles. Besides drones, traditional reconnaissance equipment often uses wheeled or quadrupedal robots, whose distinctive appearance makes them easily detectable by the enemy. Therefore, there is a need for a fully automated, integrated reconnaissance device that is concealed, capable of capturing images, remotely controlled, mobile, and easily portable. This reconnaissance device can help combat personnel understand the enemy situation inside and around buildings in advance, and formulate combat plans through environmental and enemy situation analysis to reduce blind spots in combat and avoid unnecessary casualties. This application provides a novel self-rolling reconnaissance ball, highly suitable for reconnaissance missions in urban warfare, which can improve reconnaissance efficiency and reduce combat casualties.

[0003] Spherical robots achieve movement through rolling and are characterized by omnidirectional mobility, compact structure, and strong adaptability. Currently, patent research on spherical robots mainly focuses on improving obstacle-crossing ability, motion control, and structural design.

[0004] For example, invention patent CN107215403A provides a spherical robot with obstacle-crossing and hill-climbing capabilities, employing continuously variable transmission (CVT) to adapt to different terrains and featuring a compact design; however, its drive and control systems are complex and costly. Utility model patent CN202400190U provides a spherical robot that utilizes horizontal and vertical movement devices to achieve multi-directional movement; its structural design is low-cost, but its function is limited, suitable for flat terrain, and its obstacle-crossing ability is insufficient. Control precision is low, and movement flexibility is limited. Invention patent CN116039799A provides a six-joint spherical bouncing robot that achieves bouncing ability through multi-joint design, capable of traversing certain obstacles. However, its structure is complex, and manufacturing and maintenance costs are high. Bouncing motion consumes a significant amount of energy, resulting in limited endurance. Utility model patent CN2794773Y provides an omnidirectional rolling spherical robot capable of omnidirectional rolling motion, offering high flexibility and improved movement control precision in a two-dimensional plane. Primarily suitable for flat terrain, but with poor obstacle-crossing adaptability; for example, the invention patent with publication number CN113086040A provides a modular design for an openable and reconfigurable spherical robot, suitable for various scenarios. The openable and reconfigurable design has strong scalability, supports multi-unit collaboration, and is suitable for research on group robots. However, the mechanical structure is complex, requiring advanced control algorithms and resulting in high manufacturing costs.

[0005] In summary, existing spherical robots each have their own advantages and disadvantages in terms of obstacle-crossing ability, omnidirectional movement, bouncing motion, and modular design. However, there is still no integrated spherical robot reconnaissance device that can move flexibly and capture images, thus leaving considerable room for improvement. Summary of the Invention

[0015] In the aforementioned self-rolling reconnaissance ball for urban warfare, the first connecting part is configured as a positioning protrusion, and the second connecting part is configured as a positioning recess, wherein the positioning protrusion can be inserted into the positioning recess.

[0016] The aforementioned self-rolling reconnaissance ball for urban warfare also includes a counterweight assembly connected to one side of the support, while the gear, the first motor, and the power supply element are located on the other side of the support.

[0017] In the aforementioned self-rolling reconnaissance ball for urban warfare, the counterweight assembly includes at least two counterweight blocks of different sizes.

[0041] like Figures 1-6 As shown, a self-rolling reconnaissance ball for urban warfare includes: a ball, a bracket 200, a camera 300, a drive assembly, and a power supply element 500.

[0042] The sphere is provided with a receiving cavity 101 and a detection hole 102, and the receiving cavity 101 is connected to the outside through the detection hole 102.

[0043] The bracket 200 is rotatably connected to the sphere and located within the receiving cavity 101.

[0044] Specifically, it also includes a bearing, and the ball is also provided with a rotating groove 104, which is connected to the receiving cavity 101. The bracket 200 is rotatably connected to the rotating groove 104 through the bearing.

[0045] More specifically, the bracket 200 is provided with a limiting part 210, and the bearing is located between the rotating groove 104 and the limiting part 210. The limiting part 210 can restrict the bearing within the rotating groove 104.

[0046] The camera 300 is connected to the bracket 200, and the camera 300 is aimed at the reconnaissance hole 102.

[0047] The drive assembly includes a gear ring 410, a gear 420, and a first motor 430. The gear ring 410 is connected to the bracket 200, the gear 420 is connected to the first motor 430 and meshes with the gear ring 410, and the first motor 430 is connected to the bracket 200. The first motor 430 can drive the gear 420 to rotate and drive the ball to move relative to the bracket 200 through the gear ring 410.

[0048] The power supply element 500 is connected to the bracket 200, and the camera 300 and the first motor 430 are both electrically connected to the power supply element 500. The power supply element 500 can supply power to the camera 300 and the first motor 430.

The camera 300 can capture clear images. Therefore, through the ingenious combination of the camera 300 and the drive components, the self-rolling reconnaissance ball for urban warfare can move autonomously and conduct reconnaissance in complex urban warfare environments.

[0050] like Figures 1-6 As shown, based on the above embodiment, the sphere includes two hemispheres 110, which can be joined together to form the sphere. The receiving cavity 101 is formed between the two hemispheres 110, and the detection hole 102 is located in the hemisphere 110.

[0052] like Figures 1-6 As shown, based on the above embodiment, the hemisphere 110 is provided with a first connecting part, and the gear ring 410 is provided with a second connecting part, the second connecting part being detachably connected to the first connecting part.

[0053] In this embodiment, the first connecting parts of the two hemispheres 110 are detachably connected to the gear ring 410 through the second connecting parts, thereby realizing the assembly and separation of the two hemispheres 110, achieving rapid assembly and disassembly, and greatly improving the efficiency of on-site deployment or maintenance.

[0054] like Figures 1-6 As shown, based on the above embodiment, the first connecting part is configured as a positioning protrusion 111, and the second connecting part is configured as a positioning recess 411, wherein the positioning protrusion 111 can be inserted into the positioning recess 411.

[0055] In this embodiment, the hemisphere 110 and the gear ring 410 are detachably connected by inserting the positioning protrusion 111 into the positioning recess 411. This prevents relative sliding between the hemisphere 110 and the gear ring 410 when the gear ring 410 moves the sphere relative to the bracket 200.

[0056] like Figures 1-6As shown, based on the above embodiment, a counterweight assembly is also included. The counterweight assembly is connected to one side of the support 200, and the gear 420, the first motor 430, and the power supply element 500 are located on the other side of the support 200.

[0057] Specifically, due to gravity, the counterweight assembly will always remain at the bottom of the self-rolling reconnaissance ball used in urban warfare.

[0058] In this embodiment, the counterweight assembly is located on the opposite side of other components on the support 200, thereby essentially fixing the center of gravity of the self-rolling reconnaissance ball used for urban warfare, making it more stable when rolling on different terrains and improving its applicability in complex environments.

[0059] like Figures 1-6 As shown, based on the above embodiment, the counterweight assembly includes at least two counterweight blocks 610, each counterweight block 610 having a different size. The largest counterweight block 610 is connected to the bracket 200, and the counterweight blocks 610 are connected in descending order of size.

[0060] In this embodiment, the largest counterweight 610 is connected to the support 200 and all counterweights 610 are connected in descending order of size, thus forming a structure similar to a "roly-poly toy", which can maintain the stability of the support 200 and other components even during movement.

[0061] like Figures 1-6 As shown, based on the above embodiment, a rotating connector is also included. The rotating connector is located between the counterweight assembly and the bracket 200, and the bracket 200 is rotatably connected to the counterweight assembly through the rotating connector.

[0062] In this embodiment, the support 200 is rotatably connected to the counterweight assembly via a rotating connector, allowing the support 200 to rotate freely in the horizontal direction relative to the counterweight assembly, thereby enhancing the mobility of the self-rolling reconnaissance ball used in urban warfare in confined spaces.

[0063] like Figures 1-6 As shown, based on the above embodiment, the rotating connector is a second motor 700. The second motor 700 is electrically connected to the power supply element 500, and the power supply element 500 can supply power to the second motor 700. The second motor 700 is connected to the bracket 200, and the output shaft of the second motor 700 is connected to the counterweight assembly. The second motor 700 can drive the bracket 200 to rotate relative to the counterweight assembly.

[0064] In this embodiment, the second motor 700 can drive the support 200 to rotate relative to the counterweight assembly, thereby controlling the rotation angle of the support 200 through the second motor 700, so that the camera 300 can be aligned in the desired direction, thus improving the operational accuracy of the self-rolling reconnaissance ball used in urban warfare.

[0065] like Figures 1-6 As shown, based on the above embodiment, it also includes a charging element 800. The sphere is also provided with a charging hole 103. The receiving cavity 101 is connected to the outside through the charging hole 103. The charging element 800 is connected to the bracket 200 and electrically connected to the power supply element 500. The charging element 800 can charge the power supply element 500.

[0066] Specifically, the power supply element 500 is a rechargeable battery.

[0067] In this embodiment, the charging element 800 is electrically connected to the power supply element 500 and can charge the power supply element 500, so that the self-rolling reconnaissance ball for urban street fighting can be charged with the support of an external power source when it is not in operation, reducing the need for battery replacement and extending its service life.

[0068] like Figures 1-6 As shown, based on the above embodiment, the reconnaissance hole 102 is located on the central axis of the gear ring 410, and the reconnaissance hole 102 remains stable when the gear ring 410 moves relative to the bracket 200.
