[0036] According to an embodiment of the present application, an antenna arrangement 100 is provided, with reference to Fig. 1 to Fig. 6. The antenna assembly 100 can be installed on construction machinery such as excavators, bulldozers, graders, road rollers, piling machines, etc., and is used to obtain position information, etc., of construction machinery, thereby realizing navigation, control, monitoring, etc. In the following description, the construction machinery is described using the excavator 200 as an example, but is not limited thereto.

[0037] 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, thereby determining the position, speed, time, etc. of the receiver. Optionally, the antenna body 10 can be a GNSS antenna (e.g., GPS, GLONASS, Beidou, etc.).

[0038] It is further provided that the support frame 20 comprises a support rod 21 and a first fastening frame 22, wherein the support rod 21 is connected between the antenna body 10 and the first fastening frame 22, wherein the first fastening frame 22 comprises a fastening frame body, wherein the fastening frame body is provided with a through hole for penetrating the fastening frame body in a first direction Z, wherein the through hole is used for installing a fastening element.

[0039] The first attachment frame 22 is provided with a through hole for installing a fastener, so that a detachable connection to the excavator 200 can be established directly or indirectly.

The indirect connection may consist of the first attachment frame 22 being attached to the excavator 200 via other components, wherein the first attachment frame 22 is detachably connected to the other components by installing the fastener in the through hole.

[0040] The first fixing frame 22 is provided with a through hole for installing a fixing member so that the antenna body 10 can be conveniently installed on and removed from the excavator 200 to improve the installation efficiency.

[0041] In some embodiments, the through-hole comprises a first through-hole 221, a second through-hole 222, and a third through-hole 223, wherein the first through-hole 221 is arranged at a distance from the second through-hole 222 in a second direction X, and the third through-hole 223 is arranged at a distance from the second through-hole 222 in a third direction Y. Alternatively, the first through-hole 221 extends in the second direction X, and the third through-hole 223 extends in the third direction Y, wherein the second direction X and the third direction Y intersect and are each perpendicular to the first direction Z.

[0042] The support rod 21 serves to support the antenna body 10. The support rod 21 may, for example, extend in a first direction Z, wherein the first direction Z may be an up-and-down direction, wherein the antenna body 10 is arranged on the upper side of the support rod 21 along the first direction Z, with reference to Fig. 1. This can reduce the risk of the antenna body 10 being blocked, so that the antenna body 10 has a wider field of view to improve the reliability of the received signal.

[0043] The first through-hole 221, the second through-hole 222 and the third through-hole 223 on the first fixing frame 22 can be used to penetrate the fixing frame body in the thickness direction of the fixing frame body, wherein the first through-hole 221, the second through-hole 222 and the third through-hole 223 are upper and lower through-holes, respectively, with reference to Fig. 1. The first through hole 221, the second through hole 222, and the third through hole 223 are for passing fasteners so that the first fixing frame 22 is fixed to the excavator 200, thereby installing the antenna body 10 on the excavator 200.

[0044] Furthermore, it is provided that the first through-hole 221 is arranged in a second direction X at a distance from the second through-hole 222, wherein the first through-hole 221 extends in the second direction X, wherein the first through-hole 221 is a so-called waistline hole, so that the first through-hole 221 has an adjustment space for the fastening element which extends in the second direction X. Furthermore, it is provided that the third through-hole 223 is arranged in a third direction Y at a distance from the second through-hole 222, wherein the third through-hole 223 extends in the third direction Y, wherein the third through-hole 223 is also a so-called waistline hole, so that the third through-hole 223 has an adjustment space for the fastening element which extends in the third direction Y.For example, the first direction Z, the second direction X and the third direction Y are arranged vertically in pairs.

[0045] In the case where a mounting hole is reserved for the excavator 200 and the extending direction of the mounting hole coincides with the first direction Z, a fastener may be installed in the mounting hole so that the first mounting frame 22 can be conveniently installed on the excavator.

[0046] For example, it is provided that the large arm 2021 of the excavator 200 has a first attachment hole 2021a and a second attachment hole 2021b, wherein the first attachment hole 2021a is arranged in a second direction X spaced from the second attachment hole 2021b and their extension directions respectively coincide with the first direction Z (upward and downward direction), ie the extension directions of the first attachment hole 2021a and the second attachment hole 2021b coincide with the drilling direction of the first through hole 221 and the second through hole 222, with reference to Fig. 1 and Fig. 3. During installation of the antenna assembly 100, the first through-hole 221 and the second through-hole 222 of the first mounting frame 22 can be aligned with the first mounting hole 2021a and the second mounting hole 2021b, respectively. Fasteners are installed in the first through-hole 221 and the first mounting hole 2021a, and fasteners are installed in the second through-hole 222 and the second mounting hole 2021b, so that the first mounting frame 22 is fixed to the large arm 2021, thereby achieving quick installation of the antenna body 10. When removal is required, the fasteners are removed from the mounting holes, thus achieving quick removal of the antenna body 10.Further, since the first through hole 221 extends in the second direction X, the first fixing holes 2021a and the second fixing holes 2021b can be adjusted with different pitches in the second direction X.

[0047] For example, it is provided that the large arm 2021 of the excavator 200 has a first attachment hole 2021a and a second attachment hole 2021b, wherein the first attachment hole 2021a is arranged spaced apart from the second attachment hole 2021b in a third direction Y and their extension directions respectively coincide with the first direction Z (upward and downward direction), with reference to Fig. 4. During installation of the antenna assembly 100, the second through-hole 222 and the third through-hole 223 of the first mounting frame 22 can be aligned with the first mounting hole 2021a and the second mounting hole 2021b, respectively. Fasteners are installed in the second through-hole 222 and the first mounting hole 2021a, and fasteners are installed in the third through-hole 223 and the second mounting hole 2021b, so that the first mounting frame 22 is fixed to the large arm 2021, thereby achieving quick installation of the antenna body 10. When removal is required, the fasteners are removed from the mounting holes, thus achieving quick removal of the antenna body 10.Further, since the third through hole 223 extends in the third direction Y, the first fixing holes 2021a and the second fixing holes 2021b can be adjusted with different pitches in the third direction Y.

[0048] Furthermore, a first through-hole 221, a second through-hole 222, and a third through-hole 223 are provided through the first fixing frame 22, the first through-hole 221 being spaced apart from the second through-hole 222 in a second direction X, the first through-hole 221 extending in the second direction X, the third through-hole 223 being spaced apart from the second through-hole 222 in a third direction Y, the third through-hole 223 extending in the third direction Y. The antenna body 10 is conveniently installed on and removed from the excavator 200 by means of fixing elements. The fixing holes reserved on the excavator 200 with different arrangement directions and different pitches in the same direction can be applied, thereby improving installation convenience and adaptability.In addition, when one of the first through-hole 221 and the third through-hole 223 is used for passing and fixing fasteners, the other is in an open state, so that the through-hole in the open state can be used as a bundle cable hole of the antenna connection cable.

[0049] In some embodiments, it is provided that the through-hole can only comprise a first through-hole 221 and a second through-hole 222, wherein the first through-hole 221 is arranged at a distance from the second through-hole 222 in a second direction X, ie, without the third through-hole 223. In some embodiments, it is alternatively provided that the through-hole can only comprise a second through-hole 222 and a third through-hole 223, wherein the third through-hole 223 is arranged at a distance from the second through-hole 222 in a third direction Y, ie, without the first through-hole 221.

[0050] In some embodiments, the second through-hole 222 is a round hole, with the second direction X being perpendicular to the third direction Y.

[0051] The second through-hole 222 is a round hole. When installing the antenna assembly 100, the second through-hole 222 can be used as a positioning hole. For the first mounting holes 2021a and the second mounting holes 2021b with different arrangement directions, appropriate first through-holes 221 or third through-holes 223 are selected. This facilitates quick positioning and installation to improve installation efficiency.

[0052] In some embodiments, it is provided that the support rod 21 has a first end 211 and a second end 212 which are opposite one another in the first direction Z, wherein the first end 211 is fixedly connected to the first fastening frame 22, wherein the second end 212 is connected to the antenna body 10, wherein the first fastening frame 22 further comprises a reinforcing element 225, wherein one end of the reinforcing element 225 is fixedly connected to the fastening frame body and the other end is fixedly connected to the connecting portion 213 of the support rod 21, wherein the connecting portion 213 is arranged between the first end 211 and the second end 212, with reference to Fig. 1 and Fig. 2.

[0053] The first end 211 and the first mounting frame 22 can be secured by welding, making the attachment more secure. The second end 212 is detachably connected to the antenna body 10. For example, the second end 212 is threadedly connected to the bottom of the antenna body 10 to facilitate replacement and maintenance of the antenna body 10.

[0054] One end of the reinforcement member 225 is fixedly connected to the mounting 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 formed integrally with the mounting frame body.

[0055] The first mounting frame 22 includes a reinforcement member 225, the reinforcement member 225 being fixedly connected to the connecting portion 213 of the support rod 21, the connecting portion 213 being located between the first end 211 and the second end 212. The lower position where the support rod 21 is connected to the mounting frame body and the position of the connecting portion 213 connected to the reinforcement member 225 thus form support points. That is, the support rod 21 is supported by two support points, which can improve the safety of the support rod 21.

[0056] In some embodiments, it is provided that the reinforcing element 225 comprises a first bending section 225a and a second bending section 225b which are connected to one another, wherein the first bending section 225a is arranged bent in the first direction Z with respect to the fastening frame body, wherein the second bending section 225b is arranged bent with respect to the first bending section 225a towards the support rod 21, wherein the first bending section 225a is fixedly connected to the fastening frame body, wherein the second bending section 225b is fixedly connected to the support rod 21, with reference to Fig. 1.

[0057] For example, a side edge of the mounting frame body can be bent upward to form a first bent portion 225a. The first bent portion 225a is in turn bent toward the support rod 21 to form a second bent portion 225b. Thus, the reinforcing member 225 is formed by two bends. The first bent portion 225a and the second bent portion 225b can be integrally constructed. The second bent portion 225b can be fixed to the support rod 21 by welding.

[0058] The reinforcing member 225 includes a first bending portion 225a and a second bending portion 225b connected to each other to form a stable support for the support rod 21, thereby further improving the reliability of the support rod 21 for supporting the antenna body 10.

[0059] In some embodiments, the antenna body 10 is provided with an antenna interface 11, wherein the antenna interface 11 is used to connect a terminal (not shown in the figure) of an antenna connection cable, wherein the antenna arrangement 100 further comprises the following components: an insulating component 226 arranged on the reinforcing element 225, wherein the insulating component 226 is adapted to the terminal of the antenna connection cable.

[0060] If the antenna body 10 installed on the excavator 200 requires repair, the antenna connection cable connector must be disconnected from the antenna interface 11. Since parts such as the robot arm of the excavator 200 may be live, a contact short circuit with the antenna connection cable connector may occur. This poses a risk of burnout of electrical devices connected to the antenna connection cables, such as control modules.

[0061] An insulating component 226 adapted to the antenna connection cable connector is arranged on the reinforcement member 225. When the antenna connection cable connector is removed from the antenna interface 11, the antenna connection cable connector can be temporarily secured by the insulating component 226. For example, a connector of the antenna connection cable can be plugged into the insulating component 226. This reduces the risk of the antenna connection cable connector coming into contact with electrically charged parts such as the robot arm of the excavator 200, effectively protecting the electrical devices (e.g., control modules) connected to the antenna connection cable.

[0062] For example, the insulating component 226 may be a rubber part, a glass part, or a component made of another insulating material.

[0063] In some embodiments, it is provided that the through-hole further comprises at least one first connection hole 224 for penetrating the fastening frame body in the first direction Z, wherein the support frame 20 further comprises the following components: a second fastening frame 23, which comprises a first plate element 231 and a second plate element 232 which are connected to one another, wherein the first plate element 231 is arranged bent in the first direction Z with respect to the second plate element 232, wherein the second plate element 232 is arranged bent in a third direction Y with respect to the first plate element 231, wherein the second plate element 232 is provided with at least one second connection hole 2321 for penetrating the second plate element 232 in the first direction Z, wherein the position of the second connection hole 2321 corresponds to the position of the first connection hole 224.

[0064] The first plate element 231 can be installed, for example, on the side of the robot arm 202. The first plate element 231 can be connected to the robot arm 202 either detachably or permanently, for example, 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 mounting frame 22 and the second mounting frame 23.

[0065] As a result, the first mounting frame 22 is adapted to the robot arm 202 by the second mounting frame 23, thereby realizing rapid installation and removal of the antenna body 10.

[0066] In some embodiments, the first plate element 231 is provided with a fourth through-hole 2311 and a fifth through-hole 2312 for penetrating the first plate element 231 in the third direction Y, wherein the fourth through-hole 2311 is arranged spaced apart from the fifth through-hole 2312 in a second direction X. Alternatively, the fifth through-hole 2312 extends in the second direction X.

[0067] The first connecting hole 224 on the first fixing frame 22 and the second connecting hole 2321 on the second fixing frame 23 are inserted into the fixing member, thereby achieving a detachable connection of the first fixing frame 22 to the second fixing frame 23.

[0068] In the case where a mounting hole is reserved for the excavator 200 and the extending direction of the mounting hole coincides with the third direction Y, a fastener may be installed in the mounting hole so that the second mounting frame 23 can be conveniently installed on the excavator, thereby installing the antenna body 10 on the excavator.

[0069] For example, it is provided that the large arm 2021 of the excavator 200 has a first attachment hole 2021a and a second attachment hole 2021b, wherein the first attachment hole 2021a is arranged in a second direction X spaced from the second attachment hole 2021b and their extension directions respectively coincide with the third direction Y, ie their extension directions coincide with the drilling direction of the fourth through hole 2311 and the fifth through hole 2312 of the second attachment frame 23, with reference to Fig. 5. During installation of the antenna assembly 100, the fourth through-hole 2311 and the fifth through-hole 2312 of the second mounting frame 23 can be aligned with the first mounting hole 2021a and the second mounting hole 2021b, respectively. Fasteners are installed in the fourth through-hole 2311 and the first mounting hole 2021a, and fasteners are installed in the fifth through-hole 2312 and the second mounting hole 2021b, so that the second mounting frame 23 is fixed to the large arm 2021. Thus, the first mounting frame 22 is adaptively fixed to the excavator 200 by the second mounting frame 23, thereby realizing quick installation of the antenna body 10. When removal is required, the fasteners are removed from the mounting holes, thus achieving quick removal of the antenna body 10.Furthermore, since the fifth through-hole 2312 extends in the second direction X, the first fixing holes 2021a and the second fixing holes 2021b can be adjusted with different pitches in the second direction X.

[0070] The first mounting frame 22 is adaptively mounted in a mounting hole reserved for the excavator 200 by the second mounting frame 23, which extends in the third direction Y, thereby achieving quick installation and removal of the antenna body 10. This also allows mounting holes with different pitches along the second direction X for the excavator 200 to be applied, so that adaptability can be improved while improving installation convenience.

[0071] In some embodiments, it is provided that the first plate element 231 is also provided with a sixth through-hole (not shown in the figure) for penetrating the first plate element 231 in the third direction Y, wherein the sixth through-hole is arranged in the first direction Z at a distance from the fourth through-hole 2311. Alternatively, it is provided that the sixth through-hole extends in the first direction Z.

[0072] For example, it is provided that the large arm 2021 of the excavator 200 has a first attachment hole 2021a and a second attachment hole 2021b, wherein the first attachment hole 2021a is arranged spaced apart from the second attachment hole 2021b in a first direction Z and their extension directions each coincide with the third direction Y, with reference to Fig. 6. During installation of the antenna assembly 100, the fourth through-hole 2311 and the sixth through-hole of the second mounting frame 23 can be aligned with the first mounting hole 2021a and the second mounting hole 2021b, respectively. Fasteners are installed in the fourth through-hole 2311 and the first mounting hole 2021a, and fasteners are installed in the sixth through-hole and the second mounting hole 2021b, thereby achieving quick installation of the antenna body 10. When removal is required, the fasteners are removed from the mounting holes, thus achieving quick removal of the antenna body 10. Furthermore, since the sixth through-hole extends in the first direction Z, the first mounting holes 2021a and the second mounting holes 2021b can be adjusted with different pitches in the first direction Z.

[0073] This also allows mounting holes with different pitches along the first direction Z to be applied for the excavator 200, so that adaptability can be improved while improving installation convenience.

[0074] In some embodiments, it is provided that the first plate element 231 can be provided with only a fourth through-hole 2311 and a fifth through-hole 2312, wherein the fourth through-hole 2311 is arranged at a distance from the fifth through-hole 2312 in a second direction X, i.e., without the sixth through-hole.

[0077] The third fixing frame 24 may be fixed to the excavator 200 by welding, for example, to the large arm 2021 of the excavator 200. Since the third fixing frame 24 is detachably connected to the second fixing frame 23, the second fixing frame 23 can be installed or removed with the third fixing frame 24, thereby realizing the replacement of the antenna body 10.

[0078] In some embodiments, the third fastening frame 24 is further provided with a welding hole 242 for penetrating the third fastening frame 24 in the third direction Y, wherein the plurality of fourth connecting holes 241 are arranged circumferentially around the welding holes 242.

[0079] The welding process can be performed in the welding hole 242 of the third fixing frame 24, so that the weld seam lies in the welding hole 242. Therefore, when connecting the second fixing frame 23 to the third fixing frame 24, the weld seam in the central welding hole 242 can be covered by the second fixing frame 23 to conceal the weld seam, which is more concise and beautiful in appearance.

[0080] In some embodiments, the first mounting frame 22 is detachably connected to the third mounting frame 24, wherein the third mounting frame 24 serves for attachment to the excavator 200.

In this way, it can be understood that the third fastening frame 24 is provided with a fifth connection hole for penetrating the third fastening frame 24 in the first direction Z, the position of the fifth connection hole corresponding to the position of the first connection hole 224 of the first fastening frame 22. The fastening elements are installed through the first connection hole 224 on the first fastening frame 22 and the fifth connection hole on the third fastening frame 24, thereby achieving a detachable connection of the first fastening frame 22 to the third fastening frame 24.

[0082] Of course, in some embodiments, there may be multiple ways to removably connect the first mounting frame 22 to the third mounting frame 24. For example, any one or more of the first through holes 221, second through holes 222, and third through holes 223 of the first mounting frame 22 may also correspond to the fifth connection hole, thus achieving the installation of the fastening element.
