[0066] The following is an explanation of the implementation of the "antenna device and azimuth adjustment mechanism" disclosed in the present invention through specific embodiments. Those skilled in the art can understand the advantages and effects of the present invention from the contents disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of the present invention. In addition, the drawings of the present invention are only simple schematic illustrations and are not depicted according to actual dimensions. Please note in advance. The following embodiments will further explain the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.
[0067] It should be understood that although terms such as "first," "second," and "third" may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. In addition, the term "or" as used herein may include any one or more combinations of the associated listed items, depending on the actual situation.
[0068] See also Figures 1 to 13 As shown, it is the first embodiment of the present invention. Figures 1 to 4 As shown, this embodiment discloses an antenna device 1000 suitable for 5G signal transmission or highly directional signal transmission (e.g., millimeter wave signals), but the present invention is not limited thereto. In this embodiment, the antenna device 1000 includes an azimuth adjustment mechanism 100, an antenna plate 200 mounted on the azimuth adjustment mechanism 100, a driving module 300 that drives the azimuth adjustment mechanism 100 to rotate the antenna plate 200, a heat sink 400 mounted on the antenna plate 200, and a housing 500.
[0069] The azimuth adjustment mechanism 100, antenna board 200, driver module 300, and heat sink 400 are all located within housing 500. In other words, the antenna device 1000 in this embodiment has an improved internal structure, and therefore differs from the antenna device in which any adjustment mechanism is installed externally.
[0070] It should be noted that in this embodiment, the azimuth adjustment mechanism 100 is described as being coupled to the antenna board 200, driver module 300, heat sink 400, and housing 500, but the present invention is not limited thereto. For example, in other embodiments not shown, the antenna device 1000 may omit at least one of the heat sink 400 and housing 500; alternatively, the azimuth adjustment mechanism 100 may be used independently (e.g., for sale) or in conjunction with other components. The following describes the structure of the various components of the antenna device 1000 in this embodiment, and their connections as appropriate.
[0071] like Figures 5 to 7 As shown, the azimuth adjustment mechanism 100 includes a fixed base 1, a rotating platform 2 mounted on the fixed base 1, a spacer 3 clamped between the fixed base 1 and the rotating platform 2, and a torsion spring 4 connecting the fixed base 1 and the rotating platform 2. It should be noted that the specific structures of the fixed base 1, the rotating platform 2, the spacer 3, and the torsion spring 4 can be adjusted and varied according to design requirements. However, for the sake of convenience in describing this embodiment, the azimuth adjustment mechanism 100 will be described below using only one possible configuration.
[0072] In this embodiment, the fixing base 1 is an integrally formed single-piece structure, and the fixing base 1 includes a plate body 11, a boss 12 connected to the plate body 11, a limit portion 13 upright connected to the boss 12, and two cantilevers 14 extending from the boss 12 in directions away from each other.
[0073] More specifically, the plate 11 has two parallel track grooves 111 recessed along its edge. The boss 12 is generally cylindrical and located between the two track grooves 111. Two tabs 121 are formed on the top edge of the boss 12, and a mounting post 122 is formed in the center of the boss 12. The centerline of the mounting post 122 is defined as the rotation axis R in this embodiment. Furthermore, a gasket 3 is disposed on the boss 12 and surrounds the outside of the mounting post 122. The gasket 3 is held between the two tabs 121.
[0074] Furthermore, the limiting portion 13 is located between the mounting post 122 and one of the protrusions 121, and the limiting portion 13 is generally arc-shaped and its center can be located on the rotation axis R. The limiting portion 13 can form a central angle less than 180 degrees (e.g., 70 degrees to 90 degrees) corresponding to the rotation axis R, but the present invention is not limited to this.
[0075] Two cantilever arms 14 extend from the side surface of the boss 12 toward the two track grooves 111, respectively. Each cantilever arm 14 is preferably perpendicular to the track groove 111 it faces and also perpendicular to the arrangement direction of the two protrusions 121. A positioning portion 141 (e.g., a groove) is formed at the free end of each cantilever arm 14, but the present invention is not limited thereto.
[0076] For example, in other embodiments not shown in the present invention, the fixing base 1 can omit the two cantilevers 14 (which is equivalent to omitting the two positioning portions 141); or, the fixing base 1 can directly form each positioning portion 141 on the plate body 11, and the number of positioning portions 141 of the fixing base 1 can be at least one.
[0077] The rotating platform 2 is pivotally connected to the fixed base 1 along the rotation axis R, and the rotating platform 2 can be moved relative to the fixed base 1 along the rotation axis R from an initial position (eg: Figure 7 ) is rotated counterclockwise by a first predetermined angle α1 and positioned at a first position (e.g.: Figure 8A ), or rotate clockwise from the initial position by a second predetermined angle α2 to position it in a second position (e.g.: Figure 9A ).
[0078] like Figure 8A and Figure 9A As shown, in this embodiment, the first preset angle α1 is between 0 degrees and 45 degrees (preferably: 0 degrees to 30 degrees), the second preset angle α2 is between 0 degrees and 45 degrees (preferably: 0 degrees to 30 degrees), and the first preset angle α1 and the second preset angle α2 have a difference of no more than 5 degrees (e.g.: the difference can be 0 degrees).
[0079] like Figures 5 to 7 As shown, in this embodiment, the rotating platform 2 is an integrally formed, one-piece structure and includes a pivoting section 21, two side wing sections 22 extending away from each other from the rotating platform 2, and two external connecting sections 23 extending from the two side wing sections 22. The outer contours of the pivoting section 21 and the two side wing sections 22 are similar to the contours of a bow tie. The pivoting section 21 and the two side wing sections 22 together define a receiving groove 24 on their inner sides. The pivoting section 21 is formed with two stopper grooves 211 on opposite outer sides thereof, each located between the two side wing sections 22.
[0080] Furthermore, the rotating platform 2 is rotatably disposed on the boss 12 of the fixed base 1, and the rotating platform 2 is pivotally connected to the mounting column 122 of the boss 12 along the rotation axis R through the pivot section 21, so that the gasket 3 is clamped between the pivot section 21 and the boss 12, thereby effectively reducing the friction generated by the rotating platform 2 during rotation through the gasket 3; and the two side wing sections 22 face the two cantilevers 14 respectively.
[0081] The two protrusions 121 of the boss 12 are respectively located in the two limiting grooves 211, and the limiting portion 13 passes through the pivot section 21 and is located in the accommodating groove 24. Each side wing section 22 has a top abutting portion 221 located in the accommodating groove 24, and the two top abutting portions 221 are respectively located on opposite sides of the limiting portion 13.
[0082] More specifically, the rotating platform 2 is formed with two turning fitting portions 222 (e.g., protrusions) (at the bottom edge of each side wing section 22), and any one of the turning fitting portions 222 can be used to engage with the positioning portion 141 (of the corresponding cantilever 14). Any side wing section 22 of the rotating platform 2 can be positioned in the first position (e.g., Figure 8A and Figure 8B ), and positioned in the second position (eg, Figure 9A and Figure 9B ).
[0083] It should be noted that each wing segment 22 is illustrated as having two pivoting engagement portions 222, but the present invention is not limited thereto. For example, in other embodiments not shown, the rotating platform 2 may not have any pivoting engagement portions 222; alternatively, the rotating platform 2 may have multiple pivoting engagement portions 222 formed on only one of the wing segments 22; alternatively, each wing segment 22 may further have a engagement portion formed between the two pivoting engagement portions 222 for engaging with the corresponding positioning portion 141 of the cantilever 14 to position the wing 22 in its initial position.
[0084] In this embodiment, the torsion spring 4 is formed by winding a single metal wire and includes a helically wound elastic portion 41 and two extension arms 42 extending from (the two ends of) the elastic portion 41. The elastic portion 41 of the torsion spring 4 is disposed on the mounting base 1. In this embodiment, the elastic portion 41 is sleeved and restrained by the mounting post 122 (e.g., by a screw secured to the mounting post 122). The two extension arms 42 abut against the retaining portion 13 and, respectively, against the two abutting portions 221.
[0085] Furthermore, the two ends of the elastic portion 41 are adjacent to the limit portion 13, and the torsion spring 4 abuts against the limit portion 13 and the two abutting portions 221 through the two extension arms 42 to store a preload. Figure 7 ), the two extending arms 42 abut against a plurality of contact points P between the limiting portion 13 and the two abutting portions 221, which are arranged in a row along a straight line, but the present invention is not limited thereto.
[0086] like Figure 7 、 Figure 8A ,and Figure 9AAs shown, when the rotary platform 2 rotates from the initial position, one of the extension arms 42 is driven by the corresponding abutting portion 221 to separate from the limiting portion 13 , while the other extension arm 42 separates from the corresponding abutting portion 221 and remains in contact with the limiting portion 13 .
[0087] Furthermore, when the rotating stage 2 moves from the initial position (eg Figure 7 ) rotates to a first preset angle α1 (e.g.: Figure 8A ) or a second preset angle α2 (eg: Figure 9A ), the rotating platform 2 compresses and drives one of the extension arms 42, while the other extension arm 42 abuts against the limit portion 13, so that the elastic portion 41 stores a restoring elastic force that tends to move the rotating platform 2 toward the initial position. The restoring elastic force is greater than the pre-compression force.
[0088] In addition, if Figure 5 and Figure 6 As shown, each external section 23 of the rotating platform 2 includes a first mounting portion 231 and a second mounting portion 232 connected to the first mounting portion 231. In each external section 23, the first mounting portion 231 is L-shaped and connected to the top edge of the corresponding side section 22, and the second mounting portion 232 is connected to the bottom edge of the first mounting portion 231 and is parallel to the plate 11.
[0089] like Figure 1 and Figure 4 As shown, antenna plate 200 is mounted on rotating platform 2 and positioned along rotation axis R (e.g., antenna plate 200 is fixed to first mounting portions 231 of two external sections 23 and positioned above pivot section 21 and two wing sections 22 ). Rotation axis R passes through antenna plate 200, and the normal vector of antenna plate 200 is perpendicular to rotation axis R. However, the present invention is not limited thereto. For example, antenna plate 200 can be mounted on rotating platform 2 in a manner not perpendicular to rotation axis R, depending on design requirements.
[0090] Accordingly, in this embodiment, the antenna plate 200 can be rotated to different positions along with the rotating platform 2 through the azimuth adjustment mechanism 100, so that the antenna plate 200 can change the main beam direction of the antenna plate 200 inside the antenna device 1000 to meet wider usage requirements (such as: avoiding the antenna device 1000 from reducing its applicability due to being installed in a specific position) and be suitable for more occasions.
[0091] It should be additionally explained that the shell 500 of the antenna device 1000 is preferably symmetrical about the rotation axis R, so that when the antenna plate 200 rotates to different positions along with the rotating platform 2, the parts of the shell 500 facing the antenna plate 200 are all of roughly the same structure, thereby reducing the extent to which the shell 500 affects the operation of the antenna plate 200.
[0092] like Figure 1 and Figure 11 As shown, the driving module 300 is disposed corresponding to the rotating platform 2 and can drive the rotating platform 2 to rotate. In this embodiment, the driving module 300 can drive the rotating platform 2 to rotate and position it at the first position or the second position, and the restoring elastic force is sufficient to drive the mutually engaged positioning portion 141 and any one of the steering mating portions 222 to separate from each other (e.g., Figure 8B and Figure 9B ), and drives the driving module 300 to move to the initial position, but the present invention is not limited thereto.
[0093] It should be noted that if Figures 1 to 3 As shown, the rotating platform 2 in this embodiment can be positioned at the first position or the second position by the driving module 300, rather than the mutually engaged positioning portion 141 and the corresponding steering matching portion 222 (such as: Figure 8B and Figure 9B ), but the present invention is not limited thereto. For example, in other embodiments not shown in the present invention, the driving module 300 may be used only to drive the rotating platform 2 to rotate to the first position or the second position, and then the positioning portion 141 of the rotating platform 2 is engaged with the corresponding steering mating portion 222 to position it in the first position or the second position. The restoring elastic force is used to drive the driving module 300 to move to the initial position when the mutually engaged positioning portion 141 and any steering mating portion 222 are separated from each other.
[0094] According to the above, if Figures 1 to 7 As shown, in this embodiment, the orientation adjustment mechanism 100 can be combined with the torsion spring 4 and other components (such as the limiting portion 13 and / or the two supporting portions 221) to enable the rotating platform 2 to be accurately returned to the initial position, so that the orientation of the antenna board 200 can be accurately controlled by the orientation adjustment mechanism 100.
[0095] like Figure 10 and Figure 11 As shown, the driving module 300 in this embodiment includes two electromagnets 301, a controller 302 electrically connected to the electromagnets 301, and two sliders 303 corresponding to the positions of the two electromagnets 301. The controller 302 can independently control and drive any one of the electromagnets 301 to be selectively in an ejection state (e.g., in a position Figure 10 The electromagnet 301 on the right) and a retracted state (such as: Figure 10 The electromagnet 301 on the left).
[0096] Furthermore, one possible structure of the electromagnet 301 is briefly described below, and for ease of description, the configuration of the electromagnet 301 in the ejection state is first introduced; Figure 10 As shown, the electromagnet 301 includes a frame 3011, a permanent magnet 3012 arranged at one end of the frame 3011, an electromagnetic coil 3013 located at the other end of the frame 3011, an iron core 3014 connected to the electromagnetic coil 3013 and protruding from the permanent magnet 3012, and a spring 3015 located in the frame 3011 and wound around the iron core 3014.
[0097] Furthermore, if Figure 10 As shown, when controller 302 introduces a current into electromagnetic coil 3013 to generate a magnetic field, electromagnetic coil 3013 is driven by the magnetic field to move toward permanent magnet 3012 and be magnetically fixed. Iron core 3014 is simultaneously moved so that its free end is away from permanent magnet 3012, and spring 3015 is compressed, thereby placing electromagnet 301 in the ejected state. Subsequently, when the current is stopped from being supplied to electromagnetic coil 3013, permanent magnet 3012 can magnetically fix the corresponding component (e.g., electromagnetic coil 3013), thereby maintaining electromagnet 301 in the ejected state.
[0098] Furthermore, when the controller 302 directs a reverse current to the electromagnetic coil 3013 while the electromagnet 301 is in the extended state, the electromagnetic coil 3013 is pushed away from the permanent magnet 3012, and the iron core 3014 is simultaneously moved and retracted into the frame 3011, thereby placing the electromagnet 301 in the retracted state. Subsequently, when the reverse current is stopped from being supplied to the electromagnetic coil 3013, the spring 3015 presses against the corresponding component (e.g., the electromagnetic coil 3013), thereby maintaining the electromagnet 301 in the retracted state.
[0099] In this embodiment, if Figure 1 and Figure 11 As shown, two sliders 303 are slidably positioned within the two track grooves 111 of the fixed base 1, and the two sliders 303 are connected to opposite ends of the rotating platform 2 (e.g., the two sliders 303 are respectively linked to the second mounting portions 232 of the two external sections 23). Two electromagnets 301 are respectively disposed corresponding to the opposite ends of the rotating platform 2 (e.g., the two external sections 23), and the two electromagnets 301 are also respectively disposed corresponding to the two sliders 303, so that each electromagnet 301 can push the corresponding slider 303 to rotate the rotating platform 2.
[0100] For the sake of more detailed description, the following only describes the linkage between any one electromagnet 301 and a corresponding slider 303. The slider 303 is formed with a guide surface 3031, and the iron core 3014 of each electromagnet 301 faces the guide surface 3031 of the corresponding slider 303. Figure 1 and Figure 11 As shown, when the electromagnet 301 is in the retracted state, the iron core 3014 faces (or abuts) the bottom edge of the guide surface 3031; Figure 2 and Figure 12 As shown, when the electromagnet 301 changes from the retracted state to the ejected state, the iron core 3014 pushes against the guide surface 3031 to move the slider 303 along the track groove 111 , thereby driving the corresponding external section 23 to rotate the rotary platform 2 .
[0101] Accordingly, the rotating platform 2 can be rotated and positioned at the first position (eg, Figure 2 and Figure 12 ), and the rotating stage 2 can be rotated and positioned at the second position (such as: Figure 3 and Figure 13 ).
[0102] It should be additionally explained that, in this embodiment, the rotating stage 2 is coupled with the driving module 300 and can be rotated to be positioned between a first position and a second position, but the present invention is not limited thereto.
[0103] Furthermore, in this embodiment, the driving module 300 is illustrated as each electromagnet 301 being paired with a slider 303, but the present invention is not limited thereto. For example, in other embodiments not shown, the driving module 300 may include only two electromagnets 301 without any sliders 303, and the driving module 300 may directly push the rotating stage 2 (e.g., adjacent external sections 23) via different electromagnets to rotate the rotating stage 2 to the first position or the second position. Alternatively, the driving module 300 may utilize components other than the electromagnets 301 to rotate the rotating stage 2.
[0104] [Technical Effects of the Embodiments of the Invention]
[0105] To sum up, in the antenna device disclosed in the embodiment of the present invention, the antenna plate can be adjusted in an azimuth manner so that the antenna plate can be rotated to different positions along with the rotating platform, so that the antenna device can change the main beam direction of the antenna plate inside it to meet wider usage requirements (such as: avoiding the antenna device from reducing its applicability due to being installed in a specific position) and be suitable for more occasions.
[0106] Furthermore, in the azimuth adjustment mechanism disclosed in the embodiment of the present invention, the rotating platform can be accurately returned to its initial position by combining the torsion spring with the structure of other components (such as a limiting portion and / or two supporting portions), so that the azimuth of the antenna board can be accurately controlled by the azimuth adjustment mechanism.
