As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
In the following, some embodiments of the present invention will be described in detail with reference to the accompanying drawings, and features in the following examples and examples may be combined with each other without conflict.
As shown in fig. 1 to 3, an antenna assembly 100 of an embodiment of the present invention includes: the antenna comprises a casing 10, a structural frame 20, an antenna plate 30, a first rotating shaft 11 connected between the structural frame 20 and the casing 10, and a second rotating shaft 12 connected between the antenna plate 30 and the structural frame 20. The frame 20 is rotatably connected to the casing 10 by a first rotating shaft 11, and the antenna board 30 is rotatably connected to the frame 20 by a second rotating shaft 12. Wherein the center of gravity of the antenna board 30 is located at the central axis of the antenna assembly 100 and controlled by the center of gravity of the antenna board 30 so that the antenna board 30 is in a horizontal plane. That is, the center of gravity of the antenna board 30 coincides with the center of the antenna board 30, the antenna board 30 can rotate 360 ° along the axial direction of the second rotating shaft 12, and the antenna board 30 can be kept horizontal under the action of gravity when the antenna assembly 100 is in a static state.
In this embodiment, the antenna board 30 can rotate freely relative to the frame 20 and can be kept parallel to the horizontal plane under the action of gravity. When the casing 10 and/or the structural frame 20 rotates along the axial direction of the second rotating shaft 12, the antenna board 30 can still be kept parallel to the horizontal plane under the action of gravity, so that effective coverage is achieved just below the antenna board 30. It should be noted that the antenna board 30 described in this application is in a horizontal plane or parallel to the horizontal plane, which means that the board surface of the antenna board 30 is in the horizontal plane.
Further, the center of gravity of the structural frame 20 coincides with the center of gravity of the antenna board 30. In the static state (i.e., the antenna assembly 100 is not subjected to an external force), the structural frame 20 is controlled by the center of gravity such that the plane of the structural frame 20 is in the horizontal plane. In this embodiment, the frame 20 can rotate freely relative to the housing 10 via the first rotating shaft 11, and can be kept parallel to the horizontal plane under the action of gravity. That is, the center of gravity of the structural frame 20 coincides with the center of the structural frame 20, the structural frame 20 can rotate 360 ° along the axial direction of the first rotating shaft 11, and the structural frame 20 can be kept horizontal under the action of gravity when the antenna assembly 100 is in a static state, so that the antenna board 30 can be kept horizontal without affecting the effective coverage area of the antenna board 30.
In this embodiment, the straight line of the first rotating shaft 11 is perpendicular to the straight line of the second rotating shaft 12. Since the center of gravity of the antenna board 30 coincides with the center point thereof, the center of gravity of the structural frame 20 coincides with the center point thereof, and the straight line of the first rotating shaft 11 is perpendicular to the straight line of the second rotating shaft 12, when the housing 10 is inclined in any direction, the structural frame 20 and the antenna board 30 will rotate simultaneously and automatically tend to a horizontal state due to the gravity effect through the balance adjustment of the two shafts, and at least the antenna board 30 will still remain horizontal when the antenna assembly 100 is in a static state. In the static state, the plane of the structural frame 20 and the antenna board 30 are located on the same plane.
In an embodiment, the first rotating shaft 11 of the present invention can be fixed to an outer side of the structure frame 20, the casing 10 is correspondingly provided with a first connecting portion 13, and the first connecting portion 13 is sleeved on the first rotating shaft 11. In another embodiment, the first rotating shaft 11 can be further fixed in the casing 10, the outer side of the structural frame 20 is correspondingly provided with a first connecting portion 13, and the first connecting portion 13 is sleeved on the first rotating shaft 11. The invention enables the structure frame 20 to rotate freely by 360 degrees by taking the axial direction of the first rotating shaft 11 as an axis through the structure arrangement. Of course, the first rotating shaft 11 of the present invention is not limited to this connection, and any embodiment that the structural frame 20 can freely rotate through the first rotating shaft 11 is applicable to the present invention.
In this embodiment, the combination of the first rotating shaft 11 and the first connecting portion 13 may be a set. In this embodiment, it is necessary to ensure that the weight of the structural frame 20, the first rotating shaft 11 and the antenna board 30 is not too heavy, which may affect the rotation of the structural frame 20. In an alternative embodiment, the number of the first rotating shafts 11 is two, the two first rotating shafts 11 are symmetrically disposed on two sides of the structure frame 20, and the two first connecting portions 13 are correspondingly disposed in the casing 10, so that the connection reliability of the structure frame 20 can be ensured, and the rotation smoothness of the structure frame 20 can be ensured.
In an embodiment, the second shaft 12 can be fixed to the antenna board 30, the inner side of the structural frame 20 is correspondingly provided with a second connecting portion 14, and the second connecting portion 14 is sleeved on the second shaft 12. In another embodiment, the second shaft 12 can be further fixed to the inner side of the structural frame 20, the antenna board 30 is correspondingly provided with a second connecting portion 14, and the second connecting portion 14 is sleeved on the second shaft 12. The antenna board 30 is freely rotated by 360 degrees by taking the axial direction of the second rotating shaft 12 as an axis through the structural arrangement of the present invention. Of course, the second shaft 12 of the present invention is not limited to this connection, and any embodiment that the antenna board 30 can rotate freely through the second shaft 12 is suitable for the present invention.
In this embodiment, the combination of the second shaft 12 and the second connecting portion 14 may be a set. In this embodiment, it is necessary to ensure that the weight of the second rotating shaft 12 and the antenna plate 30 is not too heavy, otherwise the rotation of the antenna plate 30 is affected. In a preferred embodiment, there are two second rotating shafts 12, two second rotating shafts 12 are symmetrically disposed on two sides of the antenna board 30, and two second connecting portions 14 are correspondingly disposed on the inner side of the structural frame 20, so that the connection reliability of the antenna board 30 can be ensured, and the rotation smoothness of the antenna board 30 can be ensured.
In the embodiment of the present invention, the casing 10 may be a hemispherical shell, and the structural frame 20 is a circular frame, wherein the center of circle of the circular frame and the center of gravity of the antenna board 30 both coincide with the center of sphere of the hemispherical shell, so that the antenna board 30 can be always parallel to the horizontal plane by using the principle of gravity. In another embodiment, the casing 10 may also be a rectangular casing, and the structural frame 20 may be a rectangular frame, wherein the center of the rectangular frame and the center of the antenna board 30 are coincident and located on the central axis of the rectangular casing, and also through the arrangement of this structure, the antenna board 30 can be ensured to be always parallel to the horizontal plane by using the principle of gravity. Of course, the shapes of the housing 10 and the structural frame 20 in the antenna assembly 100 of the present invention are not limited thereto, and may be regular shapes or irregular shapes of other structures, but at least need to satisfy the requirement of making the antenna parallel to the horizontal plane by gravity control.
