On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] It should be noted that, unless otherwise defined, all technical and scientific terms used in the specification have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0022] An embodiment of a robot dog used in a fire in the present application is shown in Figures 1-3 .

[0023] It includes a robot main body 8 provided with a foot walking mechanism 1 at the bottom, and the foot walking mechanism 1 includes four walking feet and a rudder for driving the corresponding walking feet to move. The foot walking mechanism belongs to the prior art and will not be described in detail here. The outer surface of the robot main body is coated with a heat-resistant coating.

[0024] The robot main body is also provided with a vision device and a battery 18 for supplying power to the vision device. The power supply in the present embodiment is a ternary lithium battery. In the present embodiment, the vision device includes an RGBD camera 2, a laser radar 3 and a dual-spectrum holder 4. The tail end of the robot main body is provided with a communication repeater 6. In other embodiments of the present application, the vision device can also use one or both of the existing camera and infrared thermal imager.

[0025] The outer surface of the robot body is coated with a heat-insulating high-temperature-resistant coating and a heat-insulating outer garment to prevent the electrical components from being damaged.

[0026] The left side of the robot body is provided with a battery mounting slot 9 with a notch facing left, a battery 18 is arranged in the battery mounting slot 9, and a battery protection shell 10 with an opening facing left is arranged in the battery mounting slot 9. A battery cover plate 5 is detachably connected to the opening of the battery protection shell 10. The battery is located in a heat-insulating space surrounded by the battery protection shell and the battery cover plate. The battery protection shell has a hollow interlayer 11 with a vacuum structure. The hollow interlayer 11 is a vacuum environment. An electromagnetic sleeve 12 is fixed on the shell. A battery cover plate 5 is arranged at the notch of the electromagnetic mounting slot. The battery cover plate 5 has a hollow structure. Water is arranged in the inner cavity 16 of the battery cover plate. A steam pressure relief valve 7 is arranged on the left side of the battery cover plate and communicates with the inner cavity of the battery cover plate. The power supply line for supplying power from the battery to the outside passes through the inner hole of the threading sleeve.

[0027] The front end of the battery cover plate protrudes from the front side of the battery protection shell to form a front side connecting end 14. The rear end of the battery cover plate protrudes from the rear side of the battery protection shell to form a rear side connecting end 15. The bottom of the battery cover plate protrudes from the lower side of the battery protection shell to form a lower side connecting end. The front side connecting end, the rear side connecting end, and the lower side connecting end are connected along the notch of the battery mounting slot by screws 14.

[0028] A heat-insulating lining 17 is arranged between the battery protection shell and the battery. In this embodiment, the heat-insulating lining 17 can be one or more of glass fiber, mineral wool, cellulose, polystyrene, and polyurethane.

[0029] In use, the battery protection object has a hollow interlayer with a vacuum structure, which realizes heat insulation by utilizing the vacuum structure to avoid the transmission of high temperature to the battery, and can reduce the transmission of heat to the battery in other directions except the battery cover plate. For the battery cover plate that is relatively far outside, it is more susceptible to high temperature. When affected by high temperature, the heat is first absorbed by the water in the battery cover plate, the water boils to generate steam, which is released through the steam pressure relief valve to realize the first heat absorption. When the steam is released, the air in the inner cavity of the battery cover plate is taken away. After the steam is released, the inner cavity of the battery cover plate naturally forms a vacuum environment to realize the second heat insulation, thereby reducing the influence of heat on the battery. In combination with the use of the heat-insulating high-temperature-resistant coating, the battery can be maintained in the normal working temperature range as much as possible when the external environment temperature of the robot dog is relatively high.
