[0033] In the embodiment of the present application, the second receiving module 31 is used to obtain the second position information.

It can also be other mobile operation equipment 3 that can include an antenna device, which is not limited in this application.

[0037] In the related art, since the positional relationship between the power supply cable 4 and the antenna is not fixed, the power supply cable 4 may interfere with the antenna due to factors such as vibration and movement. Such interference will not only affect the signal reception and transmission performance of the antenna, but may also cause the power supply cable 4 to wear and damage, thereby affecting the stability and reliability of the entire system.

[0038] Reference Figure 2 , Figure 3 and Figure 4 An embodiment of the present application provides an antenna device, which includes: an antenna body 1 and a limiting member 2, wherein the antenna body 1 is provided with an antenna 11; the limiting member 2 is connected to the antenna body 1, and the limiting member 2 includes a limiting portion 21, and the limiting portion 21 is used to arrange a power supply cable 4; along the radial direction of the antenna 11, there is a preset spacing distance between the limiting portion 21 and the antenna 11, so as to limit the position of the power supply cable 4 relative to the antenna 11 through the limiting member 2.

[0039] In the embodiment of the present application, the antenna body 1 includes an antenna 11, and the antenna body 1 may also include a communication unit, a receiving unit, etc. The antenna can provide communication between the GPS component and the charging pile or the lawn mowing robot. The antenna usually uses an 868 antenna, which refers to an antenna with an operating frequency of 868 MHz, which is responsible for sending the radio frequency signal from the transmitting end and transmitting the radio frequency signal received by the receiving end to the receiving end. 868 MHz belongs to the low frequency band and has the characteristics of strong penetration and good anti-interference ability. It is suitable for scenarios that require stable and reliable communication.

[0040] In the embodiment of the present application, the stopper 2 is connected to the antenna body 1, and the stopper 2 is used to fix the position of the power supply cable 4, which reduces the reliance on additional fixing devices, simplifies the structure and installation process of the antenna device, and reduces the complexity and cost of the system. This also makes the maintenance process more convenient, saving manpower and time.

[0041] In the embodiment of the present application, the limiting portion 21 can be implemented in a variety of ways, the purpose of which is to limit the range of motion of the power supply cable 4 or its related components to ensure the stable operation and safety of the equipment. The limiting portion 21 can be a limiting groove or a limiting hole. A special limiting groove or limiting hole is designed on the limiting portion 21. The power supply cable 4 can be arranged through these grooves or holes and fixed by means of a slot, a buckle, etc. to prevent the power supply cable 4 from moving or shaking. The limiting portion 21 can also be a fastener, using fasteners such as screws, bolts, and clamps to fix the power supply cable 4 at a specific position on the limiting portion 21. This method requires adjusting the tightening force to a moderate level to avoid damaging the cable. The limiting portion 21 can also be other structures that can limit the power supply cable 4, and this application does not limit this. In the embodiment of the present application, the power supply cable 4 is arranged on the limiting portion 21, so that the power supply cable 4 and the antenna 11 can maintain a positional relationship with a preset gap, so that the antenna 11 is not affected by the power supply cable 4. At the same time, arranging the power supply cable 4 on the limiting portion 21 can realize independent power supply to the antenna body 1, and the antenna device can be kept away from the charging pile. Compared with the related art in which the antenna 11 is usually fixed on the charging pile, the antenna device in the embodiment of the present application is not restricted by the charging pile and can transmit information remotely, thereby improving the remote communication performance of the antenna body 1.

[0042] The antenna device provided by the present application is provided with a limiting member 2, and the limiting member 2 can limit the position of the power supply cable 4, thereby reducing the position change of the power supply cable 4 due to vibration or movement. At the same time, since the limiting portion 21 is provided on the limiting member 2, the power supply cable 4 is arranged on the limiting portion 21, and there is a preset gap between the limiting portion 21 and the antenna 11, so that the limiting portion 21 can maintain a preset spacing distance between the power supply cable 4 and the antenna 11 in the radial direction of the antenna 11, thereby limiting the position and distance between the antenna 11 and the power supply cable 4, reducing the influence of the electromagnetic waves generated by the current in the power supply cable 4 on the received signal of the antenna 11, thereby improving the working performance of the antenna device and the stability of signal transmission.

[0043] Reference Figure 2 and Figure 4 In some embodiments of the present application, the limiting portion 21 is configured as a slot that penetrates along the extension direction of the antenna 11 .

[0044] In the embodiment of the present application, the slot can be made of flexible materials, such as rubber or silicone, which can better adapt to the shape and size of the cable. An anti-drop device can also be added to the limit portion 21, for example, an anti-drop hook or an anti-drop plate is added to the slot. When the power supply cable 4 is installed in the limit portion 21, the anti-drop hook or the anti-drop plate fixes the power supply cable 4 to prevent the power supply cable 4 from falling out of the slot due to external force.

[0045] The antenna device provided by the present application, since the limiting portion 21 is set as a card slot, the power supply cable 4 can be easily embedded in the limiting portion 21, without the need for complicated installation steps, thereby improving installation efficiency and reducing installation costs and time. The through-card slot design makes the inspection and maintenance of the power supply cable 4 more convenient, and it can be quickly disassembled and reinstalled, which is convenient for daily inspection and maintenance, reduces maintenance time and costs, and improves the maintainability of the antenna device. The card slot runs through the extension direction of the antenna 11, so that the power supply cable 4 can be installed in the card slot along the extension direction of the antenna 11, thereby improving the stability of the antenna device, reducing the relative movement between the power supply cable 4 and the antenna 11, and reducing the influence of the electromagnetic waves generated by the current in the power supply cable 4 on the signal received by the antenna 11.

[0046] Reference Figure 2 and Figure 4 In some embodiments of the present application, there are multiple limiting members 2, and the multiple limiting members 2 are distributed along the extension direction of the antenna 11.

[0047] In an embodiment of the present application, multiple limit members 2 can be evenly distributed along the extension direction of the antenna 11, or the density of the distribution of the limit members 2 can be adjusted according to the shape of the antenna 11. For example, when the antenna 11 extends in a straight line, the limit members 2 can be evenly distributed in the extension direction of the antenna 11, so that the fixed points of the power supply cable 4 are evenly distributed; when the antenna 11 extends in a curve, the distribution of the limit members 2 can be adjusted according to the curve shape of the antenna 11.

[0048] The antenna device provided by the present application has multiple limit members 2, that is, multiple limit parts 21. When the power supply cable 4 is arranged in the limit part 21, the power supply cable 4 can be fixed at multiple points, and the power supply cable 4 will not loosen as a whole due to the looseness of a single point, so as to provide a more stable fixing effect. Multiple limit members 2 are distributed along the extension direction of the antenna 11, which can limit the distance between the power supply cable 4 and the antenna 11 along the extension direction of the antenna 11, reduce the influence of the electromagnetic waves generated by the current in the power supply cable 4 on the signal received by the antenna 11, and also reduce the situation where the power supply cable 4 is entangled or knotted during use.

[0049] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of the present application, the antenna body 1 includes an antenna pole 12 , and one end of the limiting member 2 is connected to the side wall of the antenna pole 12 .

[0050] In the embodiment of the present application, the material of the antenna pole 12 can be plastic material. The plastic material is light in weight, low in cost, and has good corrosion resistance and wear resistance. In a humid and highly corrosive environment, the plastic material can maintain stable performance.

[0051] In the embodiment of the present application, one end of the limiter 2 is connected to the side wall of the antenna pole 12, and the limiter 21 can be set in the middle area of ​​the limiter 2 or at the other end of the limiter 2, but the spacing distance between the limiter 21 and the antenna 11 must not be less than a preset spacing distance.

[0052] In the embodiment of the present application, one end of the limiter 2 is connected to the side wall of the antenna pole 12. The limiter 2 can be integrally formed with the antenna pole 12, or it can be set on the side wall of the antenna pole 12 by means of a snap connection, a threaded connection, etc.

[0053] In the antenna device provided in the present application, one end of the limiter 2 is fixed on the side wall of the antenna pole 12, so that a stable connection point is formed between the limiter 2 and the antenna 11, thereby enhancing the stability of the limiter 2. The antenna pole 12 provides support for the limiter 2, so that the power supply cable 4 is better supported and protected, and the shaking and swinging of the power supply cable 4 are reduced, which can effectively resist the action of wind force and reduce the impact of wind force on the power supply cable 4 and the antenna 11.

[0054] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of the present application, the antenna pole 12 has a cavity matching the antenna 11, and the antenna 11 is accommodated in the cavity.

[0055] In the embodiment of the present application, the antenna pole 12 has a cavity matching the antenna 11, and the shape of the cavity is adapted to the shape of the antenna 11. The antenna pole 12 can also be adapted to the shape of the antenna 11, connected to the antenna 11 as a supporting structure, and the antenna pole 12 can also be arranged side by side with the antenna 11.

[0056] The antenna device provided in the present application has an antenna pole 12 with a cavity that matches the antenna 11. The antenna 11 is accommodated in the cavity, which helps to protect the antenna 11 from the influence of the external environment, such as rain, dust or mechanical damage. This can extend the service life of the antenna 11 and improve its reliability.

[0058] In the embodiment of the present application, the first receiving module 13 is used to receive the first position information. The first receiving module 13 can use the GPS component to calculate the position information such as the longitude, latitude, altitude and speed of the mobile working equipment 3 by receiving the navigation signal sent by the satellite.

[0059] In the embodiment of the present application, the GPS component can be one or dual GPS components to improve the accuracy of positioning. Since the antenna device provided by the present application is often used for outdoor operations, the GPS component has higher waterproof requirements. For example, the GPS component can be waterproofed to make the GPS component reach the IPX6 waterproof level. The IPX6 waterproof level is a level in the International Protection level system. The IPX6 waterproof level means that the device can resist the intrusion of large waves or strong water jets under certain conditions.

[0060] In the embodiment of the present application, the first communication module is connected to the antenna 11, and is also connected to the first receiving module 13, and establishes communication with the second communication module 32 of the mobile operation device 3, so as to transmit the first location information to the mobile operation device 3, and at the same time, the second location information on the mobile operation device 3 can be obtained.

[0061] In the antenna device provided in the present application, the first receiving module 13 can obtain the position information of the antenna body 1 in real time. This allows the device to obtain its current position for subsequent data processing and analysis. The first communication module can transmit the acquired position information to the second communication module 32 of the mobile operating device 3 via wireless communication. This enables the position information to be transmitted between different devices, thereby realizing the sharing of position data. Acquiring and transmitting real-time position information can enable the mobile operating device 3 to understand the position of the antenna body 1 more accurately, thereby performing more accurate operations or adjustments. For example, in a lawn mower, the positioning information of the antenna body 1 can be used to optimize the operating path. Real-time data exchange between devices through wireless communication helps to realize automated control and adjustment of the operating process and improve overall operating efficiency.

[0065] In the embodiment of the present application, the signal shielding structure 133 is disposed between the printed circuit board 132 and the receiving element 134, which can effectively reduce the signal interference between the printed circuit board 132 and the receiving element 134. This helps to ensure that the signal received by the receiving element 134 is purer, reduces the impact of interference on signal quality, and thus improves the receiving performance of the antenna 11. At the same time, it can also protect the printed circuit board 132 from external electromagnetic interference, thereby extending the service life and stability of the circuit board.
