In addition, the terms "first," "second," "third," etc. are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0047] In the description of the embodiments of this application, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0048] Reference Figures 1 to 6 An embodiment of the present application provides an antenna assembly 100 that can be installed on construction machinery such as excavators, bulldozers, graders, rollers, and pile drivers to obtain location information of the construction machinery, thereby enabling navigation, control, and monitoring. In the following description, an excavator 200 is used as an example of construction machinery, but the invention is not limited thereto.

[0049] The antenna assembly 100 includes an antenna body 10 and a support frame 20. The antenna body 10 is used to receive signals from satellites to determine the receiver's position, speed, time, etc. Optionally, the antenna body 10 can be a GNSS antenna (such as GPS, GLONASS, BeiDou, etc.).

[0050] The support frame 20 includes a support rod 21 and a first fixing frame 22. The support rod 21 is connected between the antenna body 10 and the first fixing frame 22. The first fixing frame 22 includes a fixing frame body. The fixing frame body is provided with a through hole that passes through the fixing frame body along the first direction Z. The through hole is used to install fasteners.

[0051] The first fixing frame 22 is provided with through holes for installing fasteners, thereby enabling a direct or indirect detachable connection to the excavator 200. A direct connection may involve the first fixing frame 22 being directly fixed to the excavator 200 by installing fasteners in the through holes. An indirect connection may involve the first fixing frame 22 being fixed to the excavator 200 via another component, and the first fixing frame 22 being detachably connected to the other component by installing fasteners in the through holes.

[0052] By providing the through holes for installing fasteners in the first fixing frame 22 , the antenna body 10 can be conveniently installed on and removed from the excavator 200 , thereby improving installation efficiency.

[0053] In some embodiments, the through holes include a first through hole 221, a second through hole 222, and a third through hole 223. The first through hole 221 and the second through hole 222 are spaced apart along the second direction X, and the third through hole 223 and the second through hole 222 are spaced apart along the third direction Y. Optionally, the first through hole 221 extends along the second direction X, and the third through hole 223 extends along the third direction Y. The second direction X and the third direction Y intersect and are both perpendicular to the first direction Z.

[0054] The support rod 21 is used to support the antenna body 10. As an example, refer to Figure 1 The support rod 21 can extend along a first direction Z, which can be a vertical direction, and the antenna body 10 is disposed at the top of the support rod 21 along the first direction Z. Thus, the risk of the antenna body 10 being blocked can be reduced, thereby enabling the antenna body 10 to obtain a wider field of view and improving the reliability of received signals.

[0055] Reference Figure 1 The first through hole 221, the second through hole 222, and the third through hole 223 on the first fixing bracket 22 can penetrate the fixing bracket body along its thickness. The first through hole 221, the second through hole 222, and the third through hole 223 are vertical through holes. The first through hole 221, the second through hole 222, and the third through hole 223 are used to pass fasteners through, thereby securing the first fixing bracket 22 to the excavator 200, thereby installing the antenna body 10 on the excavator 200.

[0056] The first through-hole 221 and the second through-hole 222 are spaced apart along the second direction X, and the first through-hole 221 extends along the second direction X. The first through-hole 221 is a so-called "waistline hole," thus providing adjustment space for a fastener to extend along the second direction X. The third through-hole 223 is spaced apart from the second through-hole 222 along the third direction Y, and the third through-hole 223 extends along the third direction Y. The third through-hole 223 is also a so-called "waistline hole," thus providing adjustment space for a fastener to extend along the third direction Y. As an example, the first direction Z, the second direction X, and the third direction Y are perpendicular to each other.

[0057] In the case where the excavator 200 is provided with a fastening hole, and the extending direction of the fastening hole is consistent with the first direction Z, the first fixing frame 22 can be conveniently mounted on the excavator by installing a fastener in the fastening hole.

[0058] As an example, see Figure 1 and Figure 3The boom 2021 of the excavator 200 has a first fastening hole 2021a and a second fastening hole 2021b. The first fastening holes 2021a and the second fastening holes 2021b are spaced apart along the second direction X and extend in the same direction as the first direction Z (the vertical direction). That is, the first fastening holes 2021a and the second fastening holes 2021b extend in the same direction as the opening directions of the first through holes 221 and the second through holes 222. When installing the antenna assembly 100, the first through holes 221 and the second through holes 222 of the first fixing bracket 22 can be aligned with the first fastening holes 2021a and the second fastening holes 2021b, respectively. Fasteners are installed in the first through holes 221 and the first fastening holes 2021a, and fasteners are installed in the second through holes 222 and the second fastening holes 2021b. This allows the first fixing bracket 22 to be secured to the boom 2021, thereby enabling quick installation of the antenna body 10. When disassembly is required, the fasteners can be removed from the fastening holes to achieve quick disassembly of the antenna body 10. In addition, since the first through hole 221 extends along the second direction X, it can accommodate first fastening holes 2021a and second fastening holes 2021b with different spacings along the second direction X.

[0059] As an example, see Figure 4 The boom 2021 of the excavator 200 has a first fastening hole 2021a and a second fastening hole 2021b. The first fastening holes 2021a and the second fastening holes 2021b are spaced apart along the third direction Y and extend in the same direction as the first direction Z (the vertical direction). When installing the antenna assembly 100, the second through hole 222 and the third through hole 223 of the first fixing bracket 22 are aligned with the first fastening hole 2021a and the second fastening hole 2021b, respectively. Fasteners are installed in the second through hole 222 and the first fastening hole 2021a, and in the third through hole 223 and the second fastening hole 2021b. This secures the first fixing bracket 22 to the boom 2021, thereby enabling quick installation of the antenna body 10. When disassembly is necessary, the fasteners can be removed to quickly disassemble the antenna body 10. Since the third through hole 223 extends along the third direction Y, it can accommodate the first fastening holes 2021 a and the second fastening holes 2021 b with different intervals in the third direction Y.

[0060] The first fixing bracket 22 is provided with a first through hole 221, a second through hole 222, and a third through hole 223. The first through hole 221 and the second through hole 222 are spaced apart along the second direction X, and the first through hole 221 extends along the second direction X. The third through hole 223 and the second through hole 222 are spaced apart along the third direction Y, and the third through hole 223 extends along the third direction Y. Fasteners are used to conveniently attach and detach the antenna body 10 to and from the excavator 200. The antenna body 10 is compatible with fastening holes reserved for different arrangement directions and different spacings in the same direction on the excavator 200, thereby improving installation convenience and adaptability. Furthermore, when one of the first through hole 221 and the third through hole 223 is being used for fastening, the other is idle, allowing the idle through hole to serve as a cable tie for the antenna connection wires.

[0061] In some embodiments, the through holes may include only the first through hole 221 and the second through hole 222, and the first through hole 221 and the second through hole 222 are spaced apart along the second direction X, i.e., there is no third through hole 223. Alternatively, in some embodiments, the through holes may include only the second through hole 222 and the third through hole 223, and the third through hole 223 and the second through hole 222 are spaced apart along the third direction Y, i.e., there is no first through hole 221.

[0062] In some embodiments, the second through hole 222 is a circular hole, and the second direction X is perpendicular to the third direction Y.

[0063] The second through hole 222 is a circular hole. When installing the antenna assembly 100, the second through hole 222 can be used as a positioning hole. For the first fastening holes 2021a and the second fastening holes 2021b arranged in different directions, the appropriate first through hole 221 or third through hole 223 can be selected. This facilitates quick positioning and installation, improving installation efficiency.

[0064] In some embodiments, reference Figure 1 and Figure 2 The support rod 21 includes a first end 211 and a second end 212 opposite to each other along the first direction Z, the first end 211 is fixedly connected to the first fixing frame 22, and the second end 212 is connected to the antenna body 10; the first fixing frame 22 also includes a reinforcement member 225, one end of the reinforcement member 225 is fixedly connected to the fixing frame body, and the other end is fixedly connected to the connecting portion 213 of the support rod 21, and the connecting portion 213 is located between the first end 211 and the second end 212.

[0065] The first end 211 and the first fixing frame 22 can be welded and fixed, so as to be fixed more firmly, and the second end 212 and the antenna body 10 can be detachably connected, for example, the second end 212 and the bottom of the antenna body 10 are connected by threads, which facilitates the replacement and maintenance of the antenna body 10.

[0066] One end of the reinforcement member 225 is fixedly connected to the fixing frame body, and the other end can be welded to the connecting portion 213 of the support rod 21. The reinforcement member 225 can be an integral structure with the fixing frame body.

[0067] The first fixing frame 22 includes a reinforcement member 225, and the reinforcement member 225 is fixedly connected to the connecting portion 213 of the support rod 21. The connecting portion 213 is located between the first end 211 and the second end 212. Therefore, the bottom position where the support rod 21 is connected to the fixing frame body and the position of the connecting portion 213 connected to the reinforcement member 225 both form support points, that is, the support rod 21 is supported by two support points, thereby improving the reliability of the support rod 21.

[0068] In some embodiments, reference Figure 1 The reinforcement 225 includes a first bending portion 225a and a second bending portion 225b connected to each other. The first bending portion 225a is bent along the first direction Z relative to the fixing frame body, and the second bending portion 225b is bent toward the support rod 21 relative to the first bending portion 225a. The first bending portion 225a is fixedly connected to the fixing frame body, and the second bending portion 225b is fixedly connected to the support rod 21.

[0069] As an example, a first bent portion 225a can be formed by bending one side edge of the fixing frame body upward, and then the first bent portion 225a is bent toward the support rod 21 to form a second bent portion 225b, thereby forming the reinforcement member 225 through a second bending process. The first bent portion 225a and the second bent portion 225b can be integrally formed. The second bent portion 225b can be welded to the support rod 21.

[0070] The reinforcement member 225 includes a first bending portion 225 a and a second bending portion 225 b connected to each other, which can provide a stable support for the support rod 21 , further improving the reliability of the support rod 21 in supporting the antenna body 10 .

[0071] In some embodiments, the antenna body 10 is provided with an antenna interface 11. The antenna interface 11 is used to connect to the connector of the antenna connection line (not shown). The antenna assembly 100 also includes an insulating component 226, which is provided on the reinforcement member 225 and is adapted to the connector of the antenna connection line.

[0072] When the antenna body 10 installed on the excavator 200 needs to be repaired, the connector of the antenna cable needs to be disconnected from the antenna interface 11. Since components such as the mechanical arm of the excavator 200 may be electrically charged, there is a risk of short circuiting the connector of the antenna cable, which may cause damage to electrical components connected to the antenna cable (such as the control module).

[0073] By providing an insulating component 226 on the reinforcement 225 that is compatible with the connector of the antenna connecting wire, when the connector of the antenna connecting wire is removed from the antenna interface 11, the connector of the antenna connecting wire can be temporarily fixed by the insulating component 226. For example, the connector of the antenna connecting wire can be plugged into the insulating component 226. This reduces the risk of the connector of the antenna connecting wire contacting live parts such as the mechanical arm of the excavator 200, and effectively protects electrical components connected to the antenna connecting wire (such as the control module).

[0074] As an example, the insulating component 226 may be a rubber component, a glass component, or a component made of other insulating materials.

[0075] In some embodiments, the through hole further includes at least one first connection hole 224 that penetrates the fixing frame body along the first direction Z. The support frame 20 further includes a second fixing frame 23, including a first plate 231 and a second plate 232 that are connected to each other. The first plate 231 is bent relative to the second plate 232 along the first direction Z, and the second plate 232 is bent relative to the first plate 231 along the third direction Y. The second plate 232 is provided with at least one second connection hole 2321 that penetrates the second plate 232 along the first direction Z. The position of the second connection hole 2321 corresponds to the position of the first connection hole 224.

[0076] As an example, the first plate 231 can be mounted on a side of the robotic arm 202. The first plate 231 can be detachably connected to the robotic arm 202 or fixedly connected to the robotic arm 202, such as by welding. Fasteners can be installed in the second connection hole 2321 and the first connection hole 224, thereby achieving a detachable connection between the first fixing bracket 22 and the second fixing bracket 23.

[0077] Thus, the first fixing bracket 22 is fixed to the mechanical arm 202 by means of a transfer connection via the second fixing bracket 23 , thereby enabling rapid installation and removal of the antenna body 10 .

[0078] In some embodiments, the first plate 231 is provided with a fourth through hole 2311 and a fifth through hole 2312 penetrating the first plate 231 along the third direction Y. The fourth through hole 2311 and the fifth through hole 2312 are spaced apart along the second direction X. Optionally, the fifth through hole 2312 extends along the second direction X.

[0079] The first connection hole 224 on the first fixing frame 22 and the second connection hole 2321 on the second fixing frame 23 are inserted with fasteners to achieve detachable connection between the first fixing frame 22 and the second fixing frame 23 .

[0080] In the case where the excavator 200 has a fastening hole reserved therein and the extension direction of the fastening hole is consistent with the third direction Y, the second fixing bracket 23 can be conveniently fixed to the excavator by installing fasteners in the fastening hole, thereby installing the antenna body 10 on the excavator.

[0081] As an example, see Figure 5 The arm 2021 of the excavator 200 has a first fastening hole 2021a and a second fastening hole 2021b. The first fastening hole 2021a and the second fastening hole 2021b are arranged at intervals along the second direction X and the extension directions of the first fastening hole 2021a and the second fastening hole 2021b are consistent with the third direction Y, that is, the extension directions of the first fastening hole 2021a and the second fastening hole 2021b are consistent with the opening directions of the fourth through hole 2311 and the fifth through hole 2312 of the second fixing frame 23. When installing the antenna assembly 100, the fourth through-hole 2311 and the fifth through-hole 2312 of the second fixing bracket 23 are aligned with the first fastening hole 2021a and the second fastening hole 2021b, respectively. Fasteners are installed in the fourth through-hole 2311 and the first fastening hole 2021a, and in the fifth through-hole 2312 and the second fastening hole 2021b, respectively. This secures the second fixing bracket 23 to the boom 2021. Thus, the first fixing bracket 22 is secured to the excavator 200 via the second fixing bracket 23, enabling quick installation of the antenna body 10. When disassembly is required, the fasteners are removed from the fastening holes, allowing for quick disassembly of the antenna body 10. Furthermore, since the fifth through-hole 2312 extends along the second direction X, it can accommodate first fastening holes 2021a and second fastening holes 2021b with varying spacing along the second direction X.

[0082] The first fixing bracket 22 is fixed to a fastening hole extending along the third direction Y of the excavator 200 by means of a transfer of the second fixing bracket 23, thereby realizing quick installation and disassembly of the antenna body 10, and is also applicable to fastening holes with different spacing distances in the second direction X of the excavator 200, thereby improving installation convenience and adaptability.

[0083] In some embodiments, the first plate 231 is further provided with a sixth through hole (not shown) penetrating the first plate 231 along the third direction Y. The sixth through hole is spaced apart from the fourth through hole 2311 along the first direction Z. Optionally, the sixth through hole extends along the first direction Z.

[0084] As an example, see Figure 6The boom 2021 of the excavator 200 has a first fastening hole 2021a and a second fastening hole 2021b. The first fastening hole 2021a and the second fastening hole 2021b are spaced apart along the first direction Z and extend in the same direction as the third direction Y. When installing the antenna assembly 100, the fourth through hole 2311 and the sixth through hole of the second fixing bracket 23 are aligned with the first fastening hole 2021a and the second fastening hole 2021b, respectively. Fasteners are installed in the fourth through hole 2311 and the first fastening hole 2021a, and in the sixth through hole and the second fastening hole 2021b, thereby achieving quick installation of the antenna body 10. When disassembly is required, the fasteners are removed from the fastening holes, thereby achieving quick disassembly of the antenna body 10. Furthermore, since the sixth through hole extends along the first direction Z, it can accommodate first fastening holes 2021a and second fastening holes 2021b with different spacings along the first direction Z.

[0085] Therefore, the fastening holes with different spacing distances in the first direction Z of the excavator 200 can also be applied, which improves the installation convenience and the adaptability.

[0086] In some embodiments, the first plate 231 may be provided with only the fourth through hole 2311 and the fifth through hole 2312, with the fourth through hole 2311 and the fifth through hole 2312 spaced apart along the second direction X, i.e., no sixth through hole is provided. In some embodiments, the first plate 231 may be provided with only the fourth through hole 2311 and the sixth through hole, with the sixth through hole spaced apart from the fourth through hole 2311 along the first direction Z, i.e., no fifth through hole 2312 is provided.

[0087] In some embodiments, the first plate 231 is also provided with at least one third connection hole 2313 passing through the first plate 231 along the third direction Y; the support frame 20 also includes a third fixing frame 24, and the third fixing frame 24 is provided with at least one fourth connection hole 241 passing through the third fixing frame 24 along the third direction Y, and the position of the fourth connection hole 241 corresponds to the position of the third connection hole 2313.

[0088] The third connection hole 2313 of the second fixing frame 23 and the fourth connection hole 241 of the third fixing frame 24 are used for fasteners to pass through, thereby achieving a detachable connection between the second fixing frame 23 and the third fixing frame 24 .

[0089] The third fixing frame 24 can be fixed to the excavator 200 by welding, for example, welded to the arm 2021 of the excavator 200. Since the third fixing frame 24 is detachably connected to the second fixing frame 23, the antenna body 10 can be replaced by installing or removing the second fixing frame 23 and the third fixing frame 24.

[0090] In some embodiments, the third fixing frame 24 is further provided with a welding hole 242 penetrating the third fixing frame 24 along the third direction Y, and a plurality of fourth connection holes 241 surround the welding hole 242 .

[0091] Welding operations can be performed in the welding hole 242 of the third fixing frame 24, so that the weld is in the welding hole 242. Therefore, when the second fixing frame 23 is connected to the third fixing frame 24, the weld in the middle welding hole 242 can be covered by the second fixing frame 23, shielding the weld, making the appearance more simple and beautiful.

[0092] In some embodiments, the first fixing bracket 22 and the third fixing bracket 24 are detachably connected. The third fixing bracket 24 is used to be fixed to the excavator 200. The detachable connection between the first fixing bracket 22 and the third fixing bracket 24 can eliminate the need for the second fixing bracket 23, and the antenna body 10 can be installed on the excavator 200.

[0093] Optionally, the third fixing frame 24 is provided with a fifth connection hole that passes through the third fixing frame 24 along the first direction Z, and the position of the fifth connection hole corresponds to the position of the first connection hole 224. Although not shown in the figure, the posture of the third fixing frame 24 in this embodiment can be referenced Figure 1 The third fixing frame 24 is in the posture after being flipped 90° along the imaginary axis in the second direction X. As can be understood, the third fixing frame 24 is provided with a fifth connection hole that passes through the third fixing frame 24 along the first direction Z. The position of the fifth connection hole corresponds to the position of the first connection hole 224 of the first fixing frame 22, so that the first fixing frame 22 and the third fixing frame 24 can be detachably connected by installing fasteners in the first connection hole 224 on the first fixing frame 22 and the fifth connection hole on the third fixing frame 24.

[0094] Of course, in some embodiments, there may be multiple ways to detachably connect the first fixing frame 22 and the third fixing frame 24. For example, it may be achieved by aligning any one or more of the first through hole 221, the second through hole 222, and the third through hole 223 of the first fixing frame 22 with the fifth connecting hole and installing fasteners.

[0095] The present application also provides an engineering machine, comprising: a machine body 201; a mechanical arm 202 disposed on the machine body 201; an actuator 203 disposed at the end of the mechanical arm 202; and an antenna assembly 100, wherein the antenna body 10 of the antenna assembly 100 is detachably mounted to the mechanical arm 202 via a support frame 20. Taking the excavator 200 as an example, the actuator 203 may be a bucket. The mechanical arm 202 may include a boom 2021 and a forearm 2022, with the antenna body 10 mounted to the boom 2021 via the support frame 20. If necessary, the antenna body 10 may also be mounted to the forearm 2022 via the support frame 20.

[0096] As an example, see Figure 3 The robotic arm 202 is provided with a first fastening hole 2021a and a second fastening hole 2021b, and the first fastening hole 2021a and the second fastening hole 2021b both extend along the first direction Z; the first fastening hole 2021a and the second fastening hole 2021b are arranged at intervals along the second direction X, and the first fastening hole 2021a and the second fastening hole 2021b respectively correspond to the first through hole 221 and the second through hole 222 of the first fixing frame 22, and fasteners are installed in the first fastening hole 2021a and the first through hole 221, and in the second fastening hole 2021b and the second through hole 222.

[0097] As another example, see Figure 4 The first fastening hole 2021a and the second fastening hole 2021b are arranged at intervals along the third direction Y, and the first fastening hole 2021a and the second fastening hole 2021b both extend along the first direction Z. The first fastening hole 2021a and the second fastening hole 2021b respectively correspond to the second through hole 222 and the third through hole 223 of the first fixing frame 22, and fasteners are installed in the first fastening hole 2021a and the second through hole 222, and in the second fastening hole 2021b and the third through hole 223.

[0098] For excavators 200 with fastening holes extending in the same direction as the first direction Z, the first fixing frame 22 can be conveniently mounted on the excavator by installing fasteners in the fastening holes. Furthermore, the first fixing frame 22 is compatible with fastening holes arranged in different directions on the excavator 200, as well as fastening holes spaced at different distances in the same direction, improving both installation convenience and adaptability.

[0099] In some embodiments, the robotic arm 202 is provided with a first fastening hole 2021a and a second fastening hole 2021b, both of which extend along the third direction Y; the second fixing frame 23 in the support frame 20 is connected to the first fixing frame 22.

[0100] As an example, see Figure 5 The first fastening hole 2021a and the second fastening hole 2021b are arranged at intervals along the second direction X, and the first fastening hole 2021a and the second fastening hole 2021b both extend along the third direction Y. The first fastening hole 2021a and the second fastening hole 2021b respectively correspond to the fourth through hole 2311 and the fifth through hole 2312 of the second fixing frame 23, and fasteners are installed in the first fastening hole 2021a and the fourth through hole 2311, and in the second fastening hole 2021b and the fifth through hole 2312.

[0101] As another example, see Figure 6The first fastening hole 2021a and the second fastening hole 2021b are arranged at intervals along the first direction Z, and the first fastening hole 2021a and the second fastening hole 2021b both extend along the third direction Y. The first fastening hole 2021a and the second fastening hole 2021b respectively correspond to the fourth through hole 2311 and the sixth through hole of the second fixing frame 23, and fasteners are installed in the first fastening hole 2021a and the fourth through hole 2311, and in the second fastening hole 2021b and the sixth through hole.

[0102] The first fixing bracket 22 is fixed to a fastening hole in the excavator 200 along the third direction Y through the second fixing bracket 23, thereby enabling quick removal of the antenna body 10. Furthermore, the antenna body 10 can be adapted to fastening holes arranged in different directions on the excavator 200, as well as fastening holes spaced at different intervals in the same direction, improving installation convenience and adaptability.

[0103] In some embodiments, the first fixing frame 22 and the third fixing frame 24 in the support frame 20 are connected through the second fixing frame 23, the first fixing frame 22 and the second fixing frame 23 are detachably connected, the second fixing frame 23 and the third fixing frame 24 are detachably connected, and the second fixing frame 23 is fixed to the robotic arm 202.

[0104] Since the third fixing bracket 24 is detachably connected to the second fixing bracket 23 , the antenna body 10 can be conveniently removed from and installed on the excavator 200 when it is necessary to replace or repair the antenna body 10 .

[0105] In some embodiments, the first fixing frame 22 and the third fixing frame 24 in the support frame 20 are detachably connected, and the third fixing frame 24 is fixed to the robotic arm 202 .

[0106] In the case where there are no reserved holes on the robotic arm, the third fixing frame 24 can be welded to the top surface of the robotic arm 202 along the first direction Z, and the through holes in the third fixing frame 24 (for example, the first connecting hole 224) and the fourth connecting hole 241 in the third fixing frame 24 along the first direction Z can be installed with fasteners to realize the detachable connection between the first fixing frame 22 and the third fixing frame 24.

[0107] The first fastening hole 2021a and the second fastening hole 2021b of each of the above embodiments can be reserved holes for oil pipe clamps in engineering machinery. The reserved holes for oil pipe clamps are used to fix the oil pipe clamps, which are used to clamp and position the oil supply pipelines in engineering machinery.

[0108] By utilizing the reserved holes of the oil pipe clamps in the engineering machinery as fastening holes, there is no need to open additional fastening holes in the engineering machinery, and the antenna assembly 100 can be installed and removed without damaging the engineering machinery.

[0109] In some embodiments, the upper arm 2021 and the lower arm 2022 of the robotic arm 202 are connected by a rotation axis, and the actuator 203 is disposed on the lower arm 2022. Two antenna assemblies 100 are provided, and both antenna assemblies 100 are disposed on the upper arm 2021, with one antenna assembly 100 being located near the rotation axis. Optionally, the distance between the two antenna assemblies 100 can be greater than or equal to 1.5 meters.

[0110] By installing two antenna assemblies 100 on the upper arm 2021, one close to the rotation axis, the positioning accuracy can be improved; by having the distance between the two antenna assemblies 100 be greater than or equal to 1.5 meters, the risk of mutual interference can be reduced.

[0111] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
