[0048] Next, refer to Figures 1 - 3 Describe a non-slip device for a reconnaissance robot provided according to an embodiment of the present utility model, including:

[0049] A cylindrical outer shell 100, on the outer wall of the cylindrical outer shell 100, there are provided a number of engaging teeth 110, and the engaging teeth 110 are used to engage with the crawler 400. Through this design, it can ensure the tight connection between the device and the crawler 400, increase the contact area between the crawler 400 and the ground, thereby enhancing the anti-slip ability of the robot on various complex terrains. The shape of the engaging teeth 110 can be designed into various types according to different unit bodies, such as rectangular teeth, saw teeth, etc., to adapt to different application scenarios;

[0050] An installation part 200, the installation part 200 is located at the first end of the cylindrical outer shell 100, and an inflatable airbag 210 is provided on the installation part 200;

[0051] An inflation part 300, the inflation part 300 is communicated with the inflatable airbag 210, and the inflation part 300 is located in the middle of the cylindrical outer shell 100;

[0052] Among them, the axial length of the installation part 200 is greater than or equal to the axial length of the tire of the reconnaissance robot 500, ensuring the full-contact coverage of the non-slip device and the tire. In this structure, the inflatable airbag 210 can form a uniform pressure distribution on the tire surface, increasing the friction between the tire and the cylindrical outer shell 100, and at the same time increasing the contact area with the ground, thereby increasing the grip.

[0053] Specifically, the design of the above-mentioned cylindrical housing 100 ensures that the anti-slip device can completely cover the tire, avoiding the problem of poor local anti-slip effect. The inflatable airbag 210 responds to external pressure through the inflation part 300, and can adjust the air pressure at any time according to needs to meet the anti-slip requirements of different terrains. At the same time, the reasonable design of the gear teeth 110 structure also ensures that the friction between the crawler 400 and the ground can be maximized, improving the passing ability of the robot in wet or muddy environments.

[0054] Please continue to refer to Figure 3 、 Figure 4 As shown, a number of annularly distributed clamping blocks 220 are provided on the inner wall of the installation part 200. Each inflatable airbag 210 is arranged between two adjacent clamping blocks 220. The function of the annular clamping blocks 220 is to prevent the inflatable airbag 210 from shifting during the operation of the device, ensuring that the airbag can evenly distribute pressure on the tire surface and enhancing the anti-slip effect.

[0055] It should be noted that the material of the inflatable airbag 210 is selected as a high-elasticity and high-strength rubber or similar elastomeric material. This material can rapidly expand when inflated to form a large contact area, and can rapidly contract to its original state after exhausting air. Through the fitting of the inflatable airbag 210 with the tire surface, the entire anti-slip device can effectively avoid tire slippage. This implementation method effectively fixes the inflatable airbag 210 through the annular clamping blocks 220, enabling the inflatable airbag 210 to be evenly distributed on the tire surface when inflated, preventing the problem of uneven anti-slip effect caused by the movement or deformation of the airbag. The elasticity and durability of the airbag material enable it to adapt to different terrain environments, and it can still maintain good anti-slip performance even under harsh usage conditions.

[0056] Please continue to refer to Figure 3 As shown, according to the inflation part 300 provided by the embodiment of the present invention, the inflation part 300 includes:

[0057] An air pressure tank 310, which is filled with high-pressure inert gas 320 inside. The main function of the air pressure tank 310 is to provide a stable gas source for the inflatable airbag 210. The selection of inert gas is to avoid the expansion or contraction problem of ordinary air at extreme temperatures;

[0058] An air delivery pipe 330, the two ends of which are respectively communicated with the air pressure tank 310 and the inflatable airbag 210. The air delivery pipe 330 is used to transport the gas in the air pressure tank 310 to the inflatable airbag 210;

[0059] The first pneumatic valve 340 is provided on the gas transmission pipe 330. The pneumatic valve can adjust the gas flow rate as needed to ensure that the inflatable airbag 210 maintains an appropriate pressure during operation. By controlling the opening and closing of the pneumatic valve, the airbag can be quickly inflated or deflated to meet the installation requirements for different terrains.

[0060] Specifically, through the design of the pneumatic tank 310 and the gas transmission pipe 330, the anti-slip device can provide sufficient gas for the inflatable airbag 210 in a short time, thereby increasing the contact area between the airbag and the ground and enhancing the anti-slip performance. The setting of the first pneumatic valve 340 enables the device to adjust the inflation state of the airbag during operation.

[0061] Please continue to refer to Figure 3 As shown, according to an embodiment of the present invention, the inflation part 300 further includes:

[0062] An exhaust pipe 360 that is connected to the pneumatic tank 310 and is used to quickly discharge the gas in the pneumatic tank 310 when necessary;

[0063] A second pneumatic valve 350 that is installed on the exhaust pipe 360, and the second pneumatic valve 350 is used to control the discharge speed and flow rate of the gas.

[0064] Through the design of the second pneumatic valve 350, the anti-slip device can quickly release the gas when not in use, returning the inflatable airbag 210 to its original state. This design can significantly improve the portability and flexibility of the device.

[0065] Specifically, the combined use of the exhaust pipe 360 and the second pneumatic valve 350 makes the exhaust process of the inflatable airbag 210 faster and more controllable, improving the overall response speed of the anti-slip device. In practical applications, the operator can quickly discharge or inject gas according to specific needs to adapt to complex and changing environments, thus improving the operation efficiency of the robot in various harsh environments.

[0066] Please continue to refer to Figure 3 、 Figure 5 As shown, according to another embodiment of the present invention, the inflation part 300 further includes:

[0067] A first vertical plate 370 that is installed near the installation part 200 and the gas transmission pipe 330 passes through the first vertical plate 370 and is connected to the inflatable airbag 210 to ensure that the gas transmission pipe 330 can provide a gas source for the airbag;

[0068] The second vertical plate 380 is installed on the side away from the mounting portion 200. The second vertical plate 380 and the first vertical plate 370 form a closed space. The second vertical plate 380 is provided with an opening and closing window 381 for the operator to conduct internal inspection or adjust the first air pressure valve 340 and the second air pressure valve 350 when necessary. The design of the closed space can effectively prevent the influence of the external environment on the airbag inflation system and ensure that the gas is not contaminated or leaked during the transmission process. At the same time, the design of the opening and closing window 381 simplifies the maintenance operation and reduces the difficulty of maintaining the equipment in daily use.

[0069] Specifically, the closed space formed by the first vertical plate 370 and the second vertical plate 380 ensures the stability of the air pressure system and avoids interference from the external environment. At the same time, the opening and closing window 381 makes the maintenance of the equipment more convenient. The technicians can directly check and adjust the internal structure through the opening and closing window 381, which simplifies the maintenance process and improves the reliability and operability of the equipment.

[0070] Please continue to see Figure 3 , Figure 5 As shown, according to another embodiment of the utility model, the opening and closing window 381 is hingedly mounted on the second vertical plate 380, and the first air pressure valve 340 and the second air pressure valve 350 are both directly opposite to the opening and closing window 381. The directly opposite design of the opening and closing window 381 and the air pressure valve enables the operator to directly control the working state of the air pressure valve without disassembling the device.

[0071] Specifically, the hinged opening and closing window 381 design makes the operation of the device more flexible and convenient. Through the window, the working status of the air pressure valve can be visually observed, and adjustments or maintenance can be performed when necessary without disassembling the entire anti-skid device, which saves operation time and improves the use efficiency of the equipment.

[0072] Please continue to see Figure 3 , Figure 5 As shown, according to an optional embodiment of the utility model, a sealing gasket is provided at the edge of the opening and closing window 381, and the sealing gasket is used to prevent outside air, moisture or dust from entering the enclosed space. The sealing gasket is made of highly elastic material and can completely fit the edge of the window when the window is closed to ensure the airtightness of the entire enclosed space.

[0073] Specifically, the use of the sealing gasket can effectively improve the sealing performance of the opening and closing window 381, and prevent the air pressure system from being contaminated or damaged by the outside world. At the same time, the high elasticity and wear resistance of the sealing gasket material ensure that it can still maintain a good sealing effect after long-term use, further improving the durability of the device.

[0074] According to a further embodiment of the present utility model, the gasket is made of wear-resistant and waterproof materials, such as silicone rubber: Silicone rubber has excellent high and low temperature resistance (-60°C to +200°C) and can maintain its flexibility and elasticity in various environments. It has good waterproof performance, can effectively resist the penetration of moisture, and at the same time has excellent anti-aging and wear-resistant properties, making it suitable for applications exposed to outdoor environments for a long time. Fluororubber: Fluororubber is a material with excellent chemical resistance, high temperature resistance, and wear resistance, suitable for high-temperature and corrosive environments. Its waterproof performance is excellent, especially outstanding in oil and solvent environments, so it is suitable for long-term use in complex outdoor environments. Ethylene propylene diene monomer (EPDM) rubber: EPDM rubber has excellent weather resistance, ozone resistance, and ultraviolet resistance, and is widely used as a sealing material exposed to outdoor environments. Its wear resistance and waterproof performance are also very good, and it can resist the erosion of water, acids, alkalis, and other chemical substances, making it suitable for the protection application of the reconnaissance robot 500 under changing climatic conditions. Nitrile rubber: The outstanding features of nitrile rubber are its oil resistance, wear resistance, and waterproof performance, especially suitable for working environments in contact with oils and lubricants. It also has good low-temperature resistance and tear resistance, making it suitable for use in harsh environments that the reconnaissance robot 500 may encounter.

[0075] Specifically, the selection of wear-resistant and waterproof materials significantly improves the service life of the device. Even in complex field environments, the gasket can maintain a good sealing effect for a long time, preventing external factors such as moisture and dust from damaging the air pressure system of the device and ensuring the stable operation of the device.

[0076] Please continue to refer to Figure 1 and Figure 2 As shown, in an alternative embodiment of the present utility model, it further includes a crawler 400, which is composed of modular unit bodies. Each unit body is fixedly connected to the cylindrical housing 100 through a locking tooth 110 to ensure that the entire crawler 400 structure will not loosen or fall off during operation. The surface of the unit body is covered with a high-friction material and a wear-resistant layer, such as a composite material of rubber and carbon fiber, which can provide better anti-slip and wear-resistant effects.

[0077] Specifically, the design of the modular unit body improves the flexibility and maintainability of the device. When a certain unit body is worn, it can be quickly disassembled and replaced with a single unit, reducing the maintenance cost and difficulty. The high-friction material covering the surface of the crawler 400 can effectively increase the friction between the tire and the ground, further enhancing the anti-slip performance.

[0078] In some examples of the present utility model, the unit body is installed on the cylindrical housing 100 through a detachable connection mechanism, which is convenient for replacing or maintaining the unit body on-site. Through this design, the installation and disassembly process of the entire anti-slip device is greatly simplified, improving the usability.

[0079] Specifically, through the detachable connection mechanism, the installation and disassembly of the unit body become very convenient, and technicians can complete the replacement operation without using complex tools. This design improves the adaptability of the anti-slip device, enabling it to be quickly adjusted in a variety of usage scenarios, maintaining high flexibility and practicality.
