[0030] In order to solve the technical problems mentioned in the background art, the utility model provides a jacking protective cover of AGV running in high humidity environment, AGV has the car body structure, is provided with the lifting base plate 6 on the car body structure, has the gear set 4 on the lifting base plate 6. Figure 1 、 Figure 2 As shown in the drawings, the jacking protective cover includes lower fixed plate 3, upper fixed plate 1 and enclosure 2, the lower fixed plate 3 is fixedly installed on the car body structure, the upper fixed plate 1 is fixedly installed on the lifting base plate 6, and the upper fixed plate 1 is provided with a hollow, and the gear set 4 is embedded in the hollow of the upper fixed plate 1, the enclosure 2 is a telescopic protective cover, the upper end of the enclosure 2 is connected with the outer contour of the upper fixed plate 1, and the lower end of the enclosure 2 is connected with the upper end surface of the lower fixed plate 3.

[0031] The enclosure 2 can be telescopic along with the movement of the lifting mechanism 7 during the lifting movement through the connection with the upper fixed plate 1 and the lower fixed plate 3, and an effective protective cover is formed. The telescopic structure effectively isolates the electrical components inside the car body from the external high humidity environment, thereby effectively preventing moisture from entering and ensuring the normal operation of electrical equipment. The upper fixed plate 1 and the lower fixed plate 3 ensure the stability and sealing of the entire protective cover through precise installation and connection methods, while preventing the intrusion of external dust or foreign matter. The hollow design ensures that the gear set 4 can run smoothly while ensuring the sealing of the protective cover.

[0032] The upper fixed plate 1 and the lower fixed plate 3 are respectively provided with screw holes, which are used to fix the upper fixed plate 1 on the lifting base plate 6 and the lower fixed plate 3 on the car body structure through screws. Through screw connection, the firm connection of the upper fixed plate 1 and the lower fixed plate 3 with the car body structure and the lifting base plate 6 can be ensured. This connection method not only provides stable physical support, but also effectively avoids loosening caused by vibration or external force during long-term operation. Through screw fixation, the parts of the structure can realize precise docking, and can be disassembled or repaired when needed, having good maintainability.

[0033] The outer contour of the upper fixed plate 1 is rectangular, and the enclosure 2 is designed as a multi-fold rectangular enclosure 2. The purpose of this design is to ensure that the enclosure 2 can effectively telescope during lifting movement, and maintain the stability and sealing of the structure during the telescoping process. The multi-fold rectangular enclosure 2 is composed of multiple folded parts, which can reduce space occupation through folding, ensuring maximum protection effect without affecting movement.

[0034] The multi-fold part of the enclosure 2 makes the entire protective cover have good flexibility and adaptability, and can telescope along with the lifting movement of the lifting base plate 6. When the enclosure 2 is stretched, it can form a sealed isolation area, effectively preventing moisture, dust or foreign matter from entering the car body interior, and ensuring the safe operation of electrical components.

[0035] The fence 2 can be an accordion type retractable protective cover. The fence 2 with such structure has good retractability and sealing performance, and can provide all-round protection in different operating states. The accordion type design enables the protective cover to freely retract during lifting according to actual needs, preventing sealing problems caused by changes in external environment, and ensuring stable operation of electrical components inside the vehicle body in high humidity environment.

[0037] The outer contour of the upper fixed plate 1 is larger than that of the meshing gear set 4 of the large gear and the small gear. This design ensures that the operation of the gear set 4 is not hindered, while the upper fixed plate 1 can cooperate well with the fence 2 and the lower fixed plate 3 to form a complete protective cover.

[0038] As shown in Figure 4 , the lifting base plate 6 has a driving motor (not shown) and a lifting mechanism 7. The outer contour of the upper fixed plate 1 is larger than that of the driving motor and the lifting mechanism 7. In the design, the size of the upper fixed plate 1 needs to be adjusted according to the specific size of the driving motor and the lifting mechanism 7 to ensure that the motor and the lifting mechanism 7 can work normally, and at the same time, the cooperation of the upper fixed plate 1 with the fence 2 will not be affected.

[0039] Through the cooperation of the upper fixed plate 1 with the fence 2, which is larger than the outer contour of the driving motor and the lifting mechanism 7, the lifting mechanism 7 can be enclosed from all around, ensuring that the electrical components work normally while avoiding interference from the external environment, especially the humidity or dust in the high humidity environment.

[0040] As shown in Figure 3 , the AGV has a sensor 5 for detecting rotational motion, which is installed on the upper fixed plate 1. The AGV has a sensor 5 for detecting rotational motion, which is installed on the upper fixed plate 1. The sensor 5 monitors the motion state of the lifting mechanism 7 or the gear set 4, ensures the normal operation of the motion process, and timely feedbacks possible abnormal conditions.

[0041] The height of the rectangular fence 2 when retracted cannot exceed the distance difference between the upper plane of the lifting base plate 6 and the upper plane of the box type structure vehicle body. This design limits the maximum height of the fence 2 when retracted, to ensure that the fence 2 does not affect the operation of other moving parts during lifting.

[0042] In summary, the telescopic multi-fold rectangular enclosure 2 capable of following the lifting part to make lifting movement is arranged between the upper fixed plate 1 and the lower fixed plate 3, the enclosure 2 has telescopic and sealing properties, and further forms a sealed box body for internal and external isolation, the electrical components requiring waterproof are installed in the sealed box body, so that the space is sealed during lifting, and moisture is prevented from entering the vehicle body to affect the operation of the electrical components.

[0043] The protective cover can realize full sealing of the box body inside the vehicle body with the function of top lifting, and further achieve isolation of the internal electrical components from the high-humidity environment to prevent the electrical components from being affected by humidity and accelerated failure; the protective cover can block the gap between the moving parts of the top lifting protruding from the vehicle body and the vehicle body, prevent dust and foreign matters from falling into the vehicle body to cause damage to the internal moving parts, and prevent personnel from putting hands into the vehicle body to cause crush injury, thereby playing a safety protection role.

[0044] Based on the protective cover, the embodiment further provides an AGV guide vehicle, the guide vehicle is configured with the structure of the top lifting protective cover, so that the AGV can safely operate in a high-humidity environment and ensure that the electrical equipment in the vehicle body is not affected by moisture. Through the integrated design, the AGV can continue to perform tasks in harsh environments, reduce the failure rate, and enhance the adaptability of the AGV, so that it can perform well in various complex environments.
