[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] A type of remote control, such as Figures 1-4 As shown, the device includes a housing 1, a control board 2, and an antenna 3. The housing 1 has a hollow interior forming a mounting cavity 4. The control board 2 is installed inside the mounting cavity 4. The antenna 3 is installed on one side of the back of the housing 1 and is electrically connected to the control board 2. In addition, an LCD screen 5 is provided on the control board 2, and an acrylic screen 6 is provided on the surface of the housing 1 at the location corresponding to the LCD screen 5.

[0030] This antenna 3 design allows the remote control signal to be sent to the agricultural machine's controller, enabling effective remote control. The addition of antenna 3 also effectively extends the remote control distance, making it more suitable for use in large-area scenarios and improving its applicability. Simultaneously, the LCD screen 5 clearly displays current control parameters, providing timely information. Furthermore, the control board 2 is equipped with a LoRa communication module and a Daxia Longque LR01-433 module, enabling further long-distance signal transmission and ensuring synchronization between the data displayed on the remote control and the agricultural machine's controller. This ensures the synchronization of control data between the two systems. In actual use, the remote control transmits signals to the agricultural machine's controller, which then controls the machine and sends feedback signals back to the remote control, ensuring the synchronization and consistency of information between the two systems.

[0031] The acrylic screen 6 has better light transmittance and impact resistance, and is lightweight with a smooth and glossy surface, which can more clearly display the data parameters displayed on the internal LCD screen 5, improving the overall aesthetics of the remote control.

[0032] like Figure 2 and Figure 3 As shown, a storage slot 7 for storing the antenna 3 is provided on the back of the housing 1. One end of the antenna 3 is rotatably connected to the housing 1, so the antenna 3 can be rotated to adjust its direction or stored. When not in use, the antenna 3 can be stored to reduce its volume. The antenna 3 has a rotating shaft 8 for rotatable connection. At the same time, the housing 1 is provided with a mounting slot 9 for the antenna 3 to be rotatably installed. The housing 1 is provided with a cover plate 10 that is detachably connected to the mounting slot 9. The cover plate 10 is fixed to the housing 1 with screws. The cover plate 10 is used to cover the opening of the mounting slot 9 to prevent the internal rotating shaft 8 from coming out. When assembling or disassembling the antenna 3, only the cover plate 10 needs to be disassembled or assembled. The disassembly and assembly operation is simple and convenient.

[0033] like Figures 2-4 As shown, the housing 1 includes an upper cover 11 and a lower cover 12 that fit together. The upper cover 11 and the lower cover 12 are connected by screws to make them detachable. The split structure facilitates the installation of the control board 2. The mounting cavity 4 inside the housing 1 includes an upper cavity 13 and a lower cavity 14. The upper cavity 13 is used for mounting and fixing the control board 2, and the lower cavity 14 is equipped with a lithium battery for power supply. At the same time, a charging port 16 connected to the lithium battery is provided on one side of the housing 1. In actual use, the lithium battery can be directly charged through the charging port 16 to achieve good cycle use and avoid the waste caused by frequent battery replacement, which is more environmentally friendly.

[0034] like Figure 4 As shown, a support frame is provided in the lower cavity 14. The support frame includes four side fixing plates 17 and a central frame. The side fixing plates 17 are used to abut against the side wall of the lithium battery to limit its position, so that the lithium battery can be stably installed in the lower cavity 14 and is not prone to shaking. One side of the fixing plate 17 abuts against the control plate 2 on the side away from the lithium battery, and simultaneously blocks and limits the control plate 2. The frame connects the fixing plates 17 to form a whole. The frame includes crisscrossing fixing bars 18. In this embodiment, the support frame is integrally formed with the shell 1. The frame can support the lithium battery at the bottom. The crisscrossing fixing bars 18 form a cavity 19. The design of the cavity 19 can improve the heat dissipation of the lithium battery. At the same time, the design of the frame can reduce the heat transfer of the lithium battery to the back of the shell 1, which affects the comfort of holding the battery, and simultaneously achieve good heat insulation.

[0035] like Figure 2 and Figure 3As shown, the upper part of the lower cover 12 is thicker than the lower part and forms an inclined transition surface 20 at the connection. The housing 1 adopts a shape that is thicker at the front and thinner at the rear, which makes the internal space of the upper cavity 13 larger and makes it easier to install the control board 2. The lower end of the housing 1 is thinner and easier to hold, improving the comfort of holding.

[0036] like Figure 1 As shown, the control panel 2 has multiple control buttons 21. The surface of the housing 1 has a relief groove 22 corresponding to the control buttons 21. The press adjustment control can be realized by simply installing a rubber sleeve in the relief groove 22. A sliding cover 23 is slidably connected to the front of the housing 1 along its length. The sliding cover 23 has hooks 24 on both sides. The sides of the housing 1 have grooves 25 for the hooks 24 to slide. The sliding cover 23 is designed to cover and protect the control buttons 21. When not in use, it covers the control buttons 21 on the housing 1 to prevent accidental pressing. When the control buttons 21 need to be used, simply slide the sliding cover 23 down. The operation is simple, convenient and quick. In addition, a lanyard hole 26 is reserved at the bottom of the housing 1. Users can hang a lanyard at the lanyard hole 26 as needed for easy carrying and to improve practicality.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
