When used in cold climates, low-temperature radar, as one of the key sensors for AGV navigation and obstacle avoidance, is often affected by the low temperature environment, which can easily cause frost on the radar mirror, resulting in damage to the sensor surface mirror reflection effect, thereby affecting the navigation and obstacle avoidance performance of the AGV, and even causing safety hazards. Therefore, it is necessary to defrost the mirror of the low-temperature radar. However, traditional defrosting methods usually use heating elements or chemical defrosters to defrost the mirror. Heating elements consume a lot of electrical energy, resulting in excessive energy consumption; and using chemical defrosters for defrosting is not only complicated and cumbersome, but also requires strict compliance with specific steps. In addition, its chemical composition may also have a certain negative impact on the surrounding environment, reducing its applicability. Utility Model Content

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0022] Example:

[0023] like Figure 3As shown, the utility model provides a defrosting structure for the radar mirror of an AGV, including a main body plate 11 for installing a laser scanner 21, providing a stable support and an accurate installation position for it, and two groups of defrosting components specifically facing the installation area of ​​the laser scanner 21 to ensure a full range of defrosting operations. The defrosting component includes a cylinder 31 with an air inlet and an air outlet, and an air duct for air circulation is formed inside the cylinder 31, which can effectively guide the flow path of the air and improve the defrosting efficiency. The defrosting component also includes a fan 32 that plays a driving role, and the fan 32 can forcefully push the air from the air inlet to the air outlet. Through the continuous operation of the fan 32, the cold air from the outside is continuously sucked in, and it is quickly converted into hot air with defrosting ability through the heating component, thereby achieving the defrosting effect on the radar mirror. The heating component arranged along the extension direction of the air duct is the core of the defrosting process. The number of heating components is set to more than two, which can ensure that the air in the air duct is fully and evenly heated, so that the defrosting effect is more significant and stable. A temperature sensor 35 is provided between the heating components or between the heating components and the air outlet. The temperature sensor 35 can monitor the temperature of the air flowing through the area in real time and feed back this key information to the control system in a timely manner. The entire defrosting system can intelligently adjust the speed of the fan 32 and the power of the heating components according to the real-time temperature data, thereby realizing the control of the defrosting process. It can not only ensure sufficient heat for defrosting, but also avoid damage to the equipment caused by excessive temperature, thus ensuring the efficiency and safety of the defrosting operation.

[0024] The heating includes a heating wire 34, which is arranged on a plurality of mounting plates 33 in the cylinder 31. The heating wire 34 provides an additional heat source for the defrosting operation and can quickly increase the temperature when needed to more effectively remove frost.

[0025] The main plate 11 is symmetrically provided with two groups of slots 12, and the cylinder 31 can be clamped in the slots 12, which can provide quick positioning and preliminary fixation for the cylinder 31 during initial installation. In order to further enhance the firmness and stability of the connection between the cylinder 31 and the main plate 11, screws are also used for connection. During operation, the screws pass through the screw holes pre-set on the cylinder 31 and the main plate 11 to connect the two together. The cylinder 31 is installed in an inclined state and aligned with the laser scanner 21. At the same time, a baffle 13 is also provided above the main plate 11. The baffle 13 is used in conjunction with the inclined cylinder 31 so that the hot air blown out by the defrosting component can radiate the surrounding area. There are also multiple groups of support rods 14 on the main plate 11, one end of which is clamped on the baffle 13, providing a stable support structure for the baffle 13 to ensure that it can reliably play a sunshade role.

[0026] like Figure 1 , 24, an AGV includes an AGV body 41 and a laser scanner 21. An electric control box bracket 42 is arranged above the AGV body 41. The AGV body 41 is located between the electric control box brackets 42. The electric control box brackets 42 are connected to the AGV body 41 by fixing screws, ensuring the stability and reliability of the electric control box brackets 42 during operation. At the same time, the main body plate 11 is installed on the electric control box bracket 42, and the laser scanner 21 is located above the main body plate 11 and connected to the main body plate 11 by fixing screws.

[0027] At the same time, a concave shell 22 that covers downward is provided on the top of the laser scanner 21. After the hot air blown upward from the defrost assembly encounters the concave shell 22, the wind flow can flow back and be fully utilized, which can minimize heat loss. At the same time, it can also blow through the laser scanner 21 for the second time to dry the air around the laser scanner 21 moderately and reduce the heat generation power.

[0028] A laser head column 43 is also provided above the electric control box bracket 42, and the laser head column 43 is also firmly connected to the electric control box bracket 42 by fixing screws to ensure that it will not shake or shift easily during operation. Multiple groups of through holes are provided on the laser head column 43 and the main plate 11. The connector 44 is inserted into the through hole. The laser head column 43 is further connected and fixed to the electric control box bracket 42 through the connector 44. The use of the connector 44 not only provides a reliable connection, but also has a certain elasticity and buffering performance, which can reduce the impact of vibration and impact on the equipment to a certain extent. The structure of the entire AGV is more stable, the connection between the components is more reliable, and it can maintain a good operating state in various complex working environments.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When in use, place the AGV body 41 in a suitable working position to ensure its stability. Use fixing screws to firmly install the electric control box bracket 42 on the AGV body 41. Then, install the main body plate 11 on the electric control box bracket 42 and fix it with fixing screws. Next, place the laser scanner 21 on the main body plate 11 and firmly connect it to the main body plate 11 with fixing screws.

[0031] The cylinder 31 of the defrosting assembly is clamped in the clamping groove 12 symmetrically provided on the main plate 11, and the connection is further reinforced with screws, and it is noted that the cylinder 31 is tilted and aligned with the laser scanner 21. At the same time, the baffle 13 is fixed above the main plate 11 through the support rod 14.

[0032] The heating components, the heating wire 34 and the fan 32 are installed on the mounting plate 33 inside the cylinder 31. The temperature sensor 35 is installed between the heating components or between the air outlet.

[0033] When the AGV is in a low-temperature environment and needs to be defrosted, the defrost component is started. The fan 32 starts to run, sucking the outside cold air into the cylinder 31, and converting it into hot air through the heating component such as the heating wire 34. The temperature sensor 35 monitors the air temperature in real time and feeds it back to the control system, and the system intelligently adjusts the speed of the fan 32 and the power of the heating component accordingly. The hot air blown out by the defrost component encounters the concave shell 22 and flows back, blowing the laser scanner 21 for a second time to dry the surrounding air.

[0034] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
