[0048] like Figure 1 and Figure 2 As shown, a smart agricultural machinery cab top cover includes a top cover body 1 and a light source fixing shell assembly 9. The top cover body 1 has mounting grooves for mounting the light source fixing shell assembly 9 at the front and rear ends, respectively. Specifically, a front mounting groove is provided at the front end of the top cover body 1, and two rear mounting grooves are provided at the rear end of the top cover body 1, and the two rear mounting grooves are symmetrically arranged on both sides of the rear side of the top cover body 1. The light source fixing shell assembly 9 includes a first light source fixing shell 91, a second light source fixing shell 92, and a third light source fixing shell 93. The first light source fixing shell 91 is installed in the front mounting groove by bolts, and the second light source fixing shell 92 and the third light source fixing shell 93 are installed in the two rear mounting grooves by bolts, respectively.

[0049] like Figure 5 and Figure 6As shown, the first light source fixed shell 91 is provided with a total of four lighting lamp holes 901 and two warning lamp holes 902, two lighting lamp holes 901 and one warning lamp hole 902 are provided on the left and right sides respectively, and the warning lamp holes 902 are arranged close to the outside so that the warning lamp can play a more conspicuous warning effect. The second light source fixed shell 92 and the third light source fixed shell 93 are both provided with two lighting lamp holes 901 and one warning lamp hole 902. Similarly, the warning lamp holes 902 are arranged close to the outside. The above-mentioned lighting lamp holes 901 are used to install lighting lamps, and heat dissipation fins 903 are installed on the back of the lighting lamp to increase the heat dissipation area, accelerate the heat dissipation, and thus reduce the working temperature of the lighting lamp; the warning lamp holes 902 are used to install warning lamps. In other optional embodiments, the number of lighting lamps on the first light source fixed shell 91 can be 2 or 6, etc., and the number of lighting lamps on the second light source fixed shell 92 and the third light source fixed shell can be 1 or 3, etc.

[0050] A front camera hole is provided in the middle of the first light source fixing shell 91, and a camera 18 is installed on the front side of the top cover body 1, and the camera 18 shoots the front of the tractor through the front camera hole. A rear camera hole is provided between the two rear mounting grooves at the rear end of the top cover body 1, and a camera 18 is installed on the rear side of the top cover body 1, and the camera 18 shoots the rear of the tractor through the rear camera hole. The top cover body 1 is not only equipped with cameras 18 on the front and rear sides, but also on the left and right sides, thereby increasing the monitoring and camera capabilities of the agricultural machinery. Each camera 18 is installed and connected to the top cover body 1 by bolts and rubber sealing rings, ensuring the sealing of the camera 18 hole and the stability of the camera 18 on the top cover.

[0051] In the utility model, the top surface 101 of the top cover body 1 has a first mounting platform, and the bottom inner surface 102 of the top cover body 1 has a second mounting platform. Two GNSS antennas 2 are installed on the first mounting platform, and the two GNSS antennas 2 are symmetrically arranged on both sides of the inspection port 12; the second mounting platform is installed with a perception computing unit 5 and a 5G module 6, and the perception computing unit 5 and the 5G module 6 are symmetrically arranged on the left and right sides of the skylight 11. Both the 5G module 6 and the perception computing unit 5 are installed on the second mounting platform by bolts and rubber sealing rings, which can ensure that the 5G module 6 and the perception computing unit 5 remain stable during the driving of the tractor, especially in a bumpy or vibrating environment, to avoid affecting the signal reception and computing performance due to looseness; the rubber sealing ring can also play a certain role in vibration reduction and buffering, reducing the impact of vibration on electronic equipment during the driving of the tractor.

[0052] Among them, the GNSS antenna is used to receive signals from the global navigation satellite system and provide accurate positioning information for path planning, navigation and obstacle avoidance in autonomous driving. The 5G module is used for communication between the vehicle and the outside world, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P) and vehicle-to-network (V2N). The perception computing unit is the TX2 perception computing unit, specifically the NVIDIA Jetson TX2, which is an AI edge computing module developed by NVIDIA. It supports the operation and optimization of multiple target detection algorithms and can handle tasks such as high-dimensional display and autonomous driving. The TX2 perception computing unit also has various standard hardware interfaces, which can realize connection and data collection with different sensors to ensure the real-time requirements of autonomous driving.

[0053] By setting up two GNSS antennas 2, carrier phase differential technology can be used to improve positioning accuracy, achieve centimeter-level positioning, and significantly improve the accuracy, reliability and stability of the intelligent tractor navigation system, meeting the requirements of the automatic driving system with extremely high requirements for navigation performance.

[0054] The top cover of the utility model has a top surface mounting platform and an embedded surface mounting platform, which provide an antenna mounting position and a computing module mounting position required for automatic driving. It can be seen that the top cover of the utility model integrates the components required for automatic driving of the tractor, has a higher degree of integration, can be used for more advanced intelligent driving agricultural machinery, and has strong applicability.

[0055] like Figure 4 As shown, the top cover body 1 is provided with a receiving chamber 103 with an inspection port 12 as an opening, and the receiving chamber 103 is installed with an evaporator 10. The refrigerant in the evaporator 10 changes from a low-pressure liquid state to a low-pressure gas state. The conversion process absorbs the heat in the cab, thereby achieving a cooling effect; effectively improving the temperature and humidity problems in the cab, improving the air quality in the cab, and ensuring a comfortable driving environment. There are pipes on both sides of the evaporator. The two pipes on the right are used for water flow, which are water channels and used as warm air; the left pipe is used for fluorine addition and is an air conditioning refrigeration pipe; the pipes on both sides are laid from the channel between the top cover and the cab, and the pipes pass through the pillars of the cab to the outside of the cab.

[0056] In this embodiment, a crossbeam plate 13 is provided at the rear side of the bottom of the accommodating chamber 103, and the evaporator 10 is mounted on the crossbeam plate 13; a hollow opening is provided at the front side of the bottom of the accommodating chamber 103. The crossbeam plate 13 is provided with a plurality of transverse ribs, and the evaporator 10 is placed above the transverse ribs; the crossbeam plate 13 is also provided with two screw hole seats 131, and the two ends of the evaporator 10 are fixed to the screw hole seats 131 by bolts and brackets. The transverse ribs on the crossbeam plate 13 not only increase the stability of the bottom structure of the accommodating chamber 103, but also provide a support position for the evaporator 10. There is a gap between the evaporator 10 and the crossbeam plate 13, which ensures the heat dissipation efficiency of the evaporator 10. Two heat dissipation holes are provided at the position of the crossbeam plate 13 corresponding to the evaporator 10, which further improves the heat dissipation efficiency of the evaporator 10. Both sides of the evaporator 10 are firmly fixed on the screw hole seats 131. The stable installation method ensures that the evaporator 10 will not loosen or fall off during the driving of the tractor, thereby improving the safety of use.

[0057] In other optional embodiments, in addition to the evaporator, other refrigeration components, such as an air conditioner, may be used, and a drain pipe of the air conditioner may lead to the outside of the cab through a pillar of the cab.

[0058] like Figure 1 As shown, in the present invention, the first mounting platform is also equipped with a remote control antenna 3 and a radio antenna 4, and the remote control antenna 3 and the radio antenna 4 are symmetrically arranged on the two front sides of the skylight 11. The remote control antenna 3 allows the driver to remotely control the tractor when away from the tractor, which increases the flexibility of the operation. The radio antenna 4 can be used for voice communication between agricultural machinery operation teams to enhance the collaboration and communication between teams.

[0059] like Figure 7 As shown, the top cover body 1 is provided with a skylight window 11 near the front side of the cab, and a skylight assembly 8 is provided at the skylight window 11. The skylight assembly 8 includes a skylight glass 81, an upper skylight frame 82 and a lower skylight frame 83. The skylight glass 81 is installed at the skylight window 11 corresponding to the first installation platform through the upper skylight frame 82, and the lower skylight frame 83 is installed at the skylight window 11 corresponding to the second installation platform, and the upper skylight frame 82 and the lower skylight frame 83 are fixedly connected. The structural stability of the skylight assembly 8 is enhanced by the fixed connection of the upper and lower skylight frames 83, and the upper and lower skylight frames 83 respectively seal the inspection opening 12 on the upper and lower sides, thereby increasing the sealing performance of the skylight window 11 and preventing rainwater, dust, etc. from invading the interior of the cab.

[0060] like Figure 8As shown, the top cover body 1 is provided with an inspection port 12 near the rear side of the cab, and the inspection port 12 is provided with an inspection assembly 7, which includes an inspection cover 71 and a hinge 72. One end of the inspection cover 71 is rotatably arranged on the first mounting platform through a pair of hinges 72, and the other end of the inspection cover 71 is provided with a plurality of holes corresponding to the inspection port 12; when the inspection cover 71 is rotated to close the inspection port 12, the inspection cover 71 can be fixed to the inspection port 12 by passing bolts through the corresponding plurality of holes. When the inspection port 12 needs to be opened, the bolts at one end of the inspection cover 71 are removed, and the inspection cover 71 is turned around the hinged position with the top cover to open the inspection port 12; when the inspection port 12 needs to be closed, the inspection cover 71 is closed, and one end of the inspection cover 71 is tightened and fixed by bolts. It can be seen that the inspection cover 71 is connected to the top cover through the hinge 72, making the opening and closing operations of the inspection cover 71 easier.

[0061] like Figure 4 As shown, in an optional embodiment, the four corners of the first mounting platform are provided with eye holes, and the eye holes are used to install eye bolts 14. By using a crane or a crane, the top cover can be easily lifted through the eye bolts 14 installed on the eye holes, which facilitates the disassembly and assembly of the top cover of the agricultural machinery cab and improves the working efficiency.

[0062] like Figure 3 As shown, in an optional embodiment, a positioning groove 15 is provided on the outer peripheral side of the bottom of the top cover body 1, and the positioning groove 15 is a step structure; the positioning groove 15 of the step structure can ensure that the top cover is accurately aligned with the cab during installation, thereby improving the accuracy of installation. The positioning groove 15 is provided with a plurality of recessed slots 16, and the recessed slots 16 are installed with hexagonal head bolts, and the top cover body 1 is installed and fixed to the cab by the hexagonal head bolts. The recessed slots 16 allow a certain degree of position adjustment to adapt to cabs of different models or sizes, thereby improving the adaptability and versatility of the top cover.

[0063] In an optional embodiment, the second mounting platform is provided with a plurality of blind holes 17 , which are conducting holes connecting the surface layer and the inner layer without penetrating the entire board, and are used to fasten and strengthen the top cover body.

[0064] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
