Description

Technical Field

[0001] This invention relates to an antenna structure, and more particularly to a dual-axis rotating antenna structure. Background Technology

[0002] Generally, when installing an antenna dish, installers need to try different angles of the antenna dish multiple times to find the best receiving angle, and then use mechanical fixing methods (such as screws) to fix it in the designated position. When the radiation direction of the signal source changes, such as due to the influence of the Earth's rotation, changes in the environmental conditions of the base station, or damage to the main base station causing the signal to point towards the secondary base station, the angle of the antenna dish must be manually adjusted again.

[0003] Accordingly, some manufacturers mount the antenna dish on a platform capable of yaw and pitch rotation, adjusting these two rotational dimensions to find the optimal angle. However, this type of dual-axis rotating antenna structure typically uses two motors to achieve rotation in both dimensions. This not only increases the cost of components but also complicates firmware control, and also leads to issues such as angle calibration, control circuit pin usage, and reliability problems. Therefore, there are still areas for improvement.

[0004] Therefore, a dual-axis rotating antenna structure is needed to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a dual-axis rotating antenna structure, which simplifies the structure and reduces costs through structural configuration.

[0006] According to one embodiment of the present invention, a dual-axis rotating antenna structure is provided, comprising a base, a tilting rotating bracket, an antenna assembly, a pitch rotating linkage assembly, and a drive mechanism. The base includes a central gear. The tilting rotating bracket is movably mounted on the base and tilts relative to the base. The antenna assembly is pivotally mounted on the tilting rotating bracket and includes an antenna dish. One end of the pitch rotating linkage assembly is connected to the antenna assembly. The drive mechanism is mounted on the tilting rotating bracket and includes a worm gear, a motor, and a planetary gear. The worm gear is connected to the other end of the pitch rotating linkage assembly and rotates about a first axis. The motor is connected to and drives the worm gear. The planetary gear meshes with the central gear and is driven by the worm gear to rotate about a second axis, which is orthogonal to the first axis. The rotation of the motor causes the worm gear to drive the pitch rotating linkage assembly, thereby tilting the antenna dish, and simultaneously drives the planetary gear to move along one circumference of the central gear, thereby tilting the antenna dish.

[0007] According to another embodiment of the present invention, a dual-axis rotating antenna structure is provided, comprising a base, a tilting rotating bracket, an antenna assembly, a pitch rotating linkage assembly, and a driving mechanism. The base includes a central gear. The tilting rotating bracket is movably mounted on the base and tilts relative to the base. The antenna assembly is pivotally mounted on the tilting rotating bracket and includes an antenna dish. The pitch rotating linkage assembly includes a transmission link and a driving link. One end of the transmission link is pivotally connected to the antenna assembly. One end of the driving link is pivotally connected to the other end of the transmission link. The driving mechanism drives the driving link and includes a worm gear, a motor, and a planetary gear. The worm gear is connected to the other end of the driving link and is orthogonal to the driving link. The motor is connected to and drives the worm gear. The planetary gear meshes with the central gear and is rotated by the worm gear. The rotation of the motor causes the worm gear to drive the pitch rotating linkage assembly, thereby tilting the antenna dish, and simultaneously causes the planetary gear to move along one circumference of the central gear, thereby tilting the antenna dish.

[0008] In this way, the drive mechanism can drive the antenna dish to tilt and pitch using a single motor, achieving the effects of structural simplification and cost reduction. Attached Figure Description

[0054] Please see Figure 1 and Figure 2 ,in Figure 1 A perspective schematic diagram of a dual-axis rotating antenna structure 100 according to an embodiment of the present invention is shown. Figure 2 Draw Figure 1 An exploded view of the dual-axis rotating antenna structure 100 of the embodiment. The dual-axis rotating antenna structure 100 includes a base 110, a tilting rotating support 120, an antenna assembly 130, a pitch rotating linkage 140, and a drive mechanism 150.

[0055] The base 110 includes a central gear 111. A tilting rotation bracket 120 is movably mounted on the base 110 and tilts relative to the base 110. An antenna assembly 130 is pivotally mounted on the tilting rotation bracket 120 and includes an antenna dish 131. One end of a pitch rotation linkage 140 is connected to the antenna assembly 130. A drive mechanism 150 is mounted on the tilting rotation bracket 120 and includes a worm gear 151, a motor 152, and a planetary gear 154. The worm gear 151 is connected to the other end of the pitch rotation linkage 140. The motor 152 is connected to and drives the worm gear 151. The planetary gear 154 meshes with the central gear 111 and is rotated by the worm gear 151. The rotation of the motor 152 causes the worm gear 151 to drive the pitch rotation linkage 140, thereby tilting the antenna dish 131, and simultaneously driving the planetary gear 154 along a circumferential direction R1 (shown on...) of the central gear 111. Figure 6 The antenna dish 131 is moved to cause it to tilt.

[0056] In this way, the drive mechanism 150 can drive the antenna dish 131 to tilt and pitch using a single motor 152, thereby achieving the effects of structural simplification and cost reduction.

[0057] The base 110 is generally disc-shaped, and a central gear 111 may protrude from the upper surface of the base 110, and the central gear 111 includes a gear hole. The body of the base 110 and the central gear 111 can be integrally molded using plastic parts. The dual-axis rotating antenna structure 100 may also include a control circuit board 160 and a heat sink 170, and the control circuit board 160 and the heat sink 170 are stacked on the side of the base 110 away from the yaw rotation support 120. The control circuit board 160 can be used to control the drive mechanism 150, and the heat sink 170 provides heat dissipation for the control circuit board 160.

[0058] The yaw rotation bracket 120 may include a base plate 121 and two arms 122, with the two arms 122 protruding from the base plate 121 at intervals. The yaw rotation bracket 120 may also include a limiting protrusion (not shown), which protrudes from the lower surface of the base plate 121 facing the base 110 and is pivotally mounted in a gear hole, thereby allowing the yaw rotation bracket 120 to yaw relative to the base 110, that is, to rotate in the X-axis and Y-axis planes.

[0059] The base plate 121 is elongated and includes two side edges. Each support arm 122 is connected to the side edge and is opposite to each other, thus forming a support structure on which the antenna assembly 130 is pivotally mounted. The tilting and rotating bracket 120 may also include a through hole 123 and a motor fixing part 124. The through hole 123 penetrates the base plate 121, and the motor fixing part 124 protrudes upward from an upper surface of the base plate 121, so that the motor 152 can be fixed thereon.

[0060] Furthermore, the dual-axis rotating antenna structure 100 may also include a plurality of rotating wheels 180, which are pivotally mounted at intervals on the lower surface of the base plate 121 and in contact with the base 110. For example... Figure 2 As shown, there are three rotating wheels 180. The oscillating rotation support 120 may also include three pivots 125, which are spaced apart on the lower surface of the base plate 121, and each rotating wheel 180 is pivotally mounted on its respective pivot 125. In this way, each rotating wheel 180 provides rotational support, preventing the base plate 121 from deforming due to gravity. Furthermore, the rotating wheels 180 improve the smoothness of rotation of the oscillating rotation support 120 relative to the base 110 and can replace bearings, thus reducing costs.

[0061] The motor 152 of the drive mechanism 150 can be fixed to the motor fixing part 124. One end of the worm 151 can be directly connected to the output shaft of the motor 152. The extension direction of the worm 151 can be parallel to a first axis L1 and includes multiple worm teeth 1511. When the motor 152 drives the worm 151, the worm 151 can rotate around the first axis L1. The drive mechanism 150 may also include a transmission gear 153 that meshes with the worm 151, especially with the worm teeth 1511. The planetary gear 154 may include a gear disk 1541 and a cylindrical part 1542. The gear disk 1541 meshes with the central gear 111. The cylindrical part 1542 extends upward from the gear disk 1541 and passes through the through hole 123. The transmission gear 153 is locked to one end of the cylindrical part 1542.

[0062] Specifically, the transmission gear 153 is rotatably located above the base plate 121, and the planetary gear 154 is located below the base plate 121, with the cylindrical portion 1542 passing through the through hole 123 to connect with the transmission gear 153. Thus, the planetary gear 154 can be confined within the tilting rotating bracket 120 and rotate together with the transmission gear 153. Therefore, when the motor 152 rotates, the worm gear 1511 on the worm 151 rotates, causing the transmission gear 153 and the planetary gear 154 to rotate around a second axis L2. Since the center of the base 110 is pivotally connected to the center of the tilting rotating bracket 120, the planetary gear 154 meshes with the central gear 111. Therefore, the planetary gear 154 can also drive the tilting rotating bracket 120 to move circumferentially R1 around the central gear 111, causing the antenna dish 131 to tilt. The second axis L2 can be orthogonal to the first axis L1. Figure 1 In the diagram, the first axis L1 can be parallel to the X-axis, and the second axis L2 can be parallel to the Z-axis.

[0063] Antenna assembly 130 is pivotally connected to the two arms 122. Specifically, antenna assembly 130 may further include an antenna support frame 132, which is connected to the antenna dish 131 and pivotally connected between the two arms 122. The antenna support frame 132 further includes two arm portions 1321 and a locking plate portion 1322, with the two arm portions 1321 protruding from the locking plate portion 1322 at intervals. The antenna dish 131 is connected between the two arm portions 1321, and the two arm portions 1321 are respectively pivotally connected to the two arms 122.

[0064] The locking plate portion 1322 is connected to the two arm portions 1321 in an n-shaped structure. Each locking plate portion 1322 includes a locking hole facing the antenna dish 131, and can be locked and fixed with the antenna dish 131. The antenna support frame 132 may also include two arm pivots 1323, which protrude outward from the outer surface of the arm portion 1321 and can be pivotally connected to the pivot holes of the two arms 122 respectively. The antenna support frame 132 may also include a connecting rod pivot 1324, which protrudes outward from the outer surface of one of the arms 1321 and is spaced apart from the arm pivot 1323 along the extension direction of the arm portion 1321. Furthermore, the antenna assembly 130 may also include a heat sink 133, which can be locked to the locking plate portion 1322. Specifically, the heat sink 133 is locked to a surface of the locking plate portion 1322 away from the arm portion 1321, and the heat sink 133 may include a flat surface for an antenna circuit board to be disposed thereon.

[0065] Please see Figure 3 , Figure 4 as well as Figure 5 See also Figure 1 and Figure 2 ,in Figure 3 Draw Figure 1 A partial side view of the dual-axis rotating antenna structure 100 in this embodiment. Figure 4 Draw Figure 1 A schematic diagram of an equivalent connecting rod of the dual-axis rotating antenna structure 100 in this embodiment. Figure 5 Draw Figure 1 A partial side view of the operation diagram of the dual-axis rotating antenna structure 100 in the embodiment. Please note. Figure 3 and Figure 5Only some components of the dual-axis rotating antenna structure 100 are shown, but this is not intended to limit the invention. The pitch rotation linkage 140 is used to drive the antenna assembly 130 in pitch rotation, and may include a transmission link 141 and a drive link 142. The transmission link 141 is pivotally connected to one of the two arms 1321, and the drive link 142 is pivotally connected between the transmission link 141 and the worm gear 151. Specifically, the extension direction of the drive link 142 is perpendicular to the worm gear 151, and both ends of the drive link 142 are pivotally connected to the transmission link 141 and the worm gear 151, respectively. The extension direction of the transmission link 141 is also perpendicular to the worm gear 151, and one end of the transmission link 141 is pivotally connected to the drive link 142, forming a variable angle. The other end of the transmission link 141 is pivotally connected to the link pivot 1324.

[0066] In this way, it is possible to form such as Figure 4 The planar four-bar linkage shown in the diagram is such that the driving link 142 can be equivalent to link B1, the transmission link 141 can be equivalent to link B2, the line connecting the link pivot 1324 on the arm 1321 and the support arm pivot 1323 can be equivalent to link B3, and the line connecting the driving link 142 to the aforementioned end (fixed point) of the worm gear 151 and the link pivot 1324 (fixed point) can be equivalent to link B0. When link B1 rotates continuously, link B3 can swing and rotate relative to the fixed point.

[0067] In terms of configuration, the length of the drive link 142 and the length of each arm 1321 can be less than the length of the transmission link 141, and the aforementioned lengths refer to the lengths between pivot points. Furthermore, the lengths of links B1 and B3 must be less than the lengths of links B0 and B2. The lengths of links B1 and B3 can be equal, and the lengths of links B0 and B2 can be equal, but these two equations cannot coexist.

[0068] like Figure 5 As shown, the rotation of the worm gear 151 can drive the drive link 142 to rotate around the first axis L1, and drive the transmission link 141 to pull the antenna assembly 130. The antenna assembly 130 will rotate in pitch about the link pivot 1324 as the axis of rotation, causing the antenna dish 131 to swing between a first yaw position and a second yaw position. The angle difference between the first yaw position and the second yaw position is greater than or equal to 65 degrees and less than or equal to 85 degrees, for example, 77.17 degrees.

[0069] Please see Figure 6 See also Figure 1 and Figure 2 ,in Figure 6 Draw Figure 1This is a partial top view of the dual-axis rotating antenna structure 100 in this embodiment. In this embodiment, when the motor 152 rotates, it can simultaneously tilt and yaw the antenna assembly 130. Therefore, the antenna assembly 130 can be slowly tilted while continuously tilting back and forth, which helps to achieve global scanning. Thus, the tilting angle of the tilting rotating bracket 120 can be θ. yaw The rotation angle of motor 152 is The pitch circle diameter of planetary gear 154 is D. p The pitch circle diameter of the center gear 111 is D. c The number of teeth on the worm gear 151 is T. w and satisfy The relationship.

[0070] Rotation angle of motor 152 Accumulated, pitch circle diameter D p It is the distance from the center point of planetary gear 154 to the junction point of planetary gear 154 and center gear 111, and the pitch circle diameter D. c It is the distance T between the center point of the central gear 111 and the junction of the central gear 111 and the planetary gear 154. w That is, the number of teeth in the 1511 cochlear tooth.

[0071] Therefore, when the motor 152 rotates one revolution, the spatial directivity of the antenna assembly 130 will follow a fixed curve and adhere to a harmonious curve on the spatial sphere, and this spatial directivity is only related to the rotation angle of the motor 152. This is related and can be considered as the rotation angle of motor 152. It is a one-dimensional function, therefore unique, which is beneficial for scanning search algorithms for the optimal signal. For example, if the scanning range is from the rotation angle... The search range is from +3600 degrees to -3600 degrees, meaning the range of ±10 revolutions of motor 152. If the optimal signal is located at 456 degrees, this is because the pointing position and rotation angle... It is unique, so it can easily return to the optimal position of the detected signal, and can even achieve the effect of accurately returning to the optimal position.

[0072] Furthermore, in addition to achieving the advantages of simplified structure, reduced cost, and accurate return to the optimal position, this invention also helps improve product reliability by reducing the number of motors. Assuming that the reliability of a single motor is 95% over a period of time, a design using two motors can be considered a series system, where the reliability becomes the product of the two motors, 90.25%, resulting in a decrease in reliability. Therefore, by reducing the number of motors, product reliability can be improved.

[0073] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the appended claims.
