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] Furthermore, the existing antenna dish is mounted on a platform that can only yaw rotate, so its search range is limited to one rotation dimension and it is not easy to adjust to the optimal angle. Therefore, there is still room 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, through structural configuration, allows the antenna dish to be adjusted to the optimal angle.

[0006] According to one embodiment of the present invention, a dual-axis rotating antenna structure is provided, comprising a base, a tilting rotation mechanism, and an antenna module. The tilting rotation mechanism includes a tilting rotation bracket, which is movably disposed on the base and tilts relative to the base. The antenna module includes an elevation rotation assembly and an antenna assembly. The elevation rotation assembly includes an elevation rotation bracket, which is movably disposed on the tilting rotation bracket and tilts relative to the tilting rotation bracket. The antenna assembly is disposed on the elevation rotation bracket and includes an antenna dish. The tilting rotation bracket and the elevation rotation bracket drive the antenna dish to tilt and tilt, thereby adjusting a tilt angle and an elevation angle of the antenna dish.

[0007] According to another embodiment of the present invention, a dual-axis rotating antenna structure is provided, comprising a tilting rotation mechanism and an antenna module. The tilting rotation mechanism includes a tilting rotation bracket. The antenna module includes a pitch rotation motor, a pitch rotation gear, an arc gear, and an antenna assembly. The pitch rotation motor is disposed on the tilting rotation bracket. The pitch rotation gear is connected to and driven by the pitch rotation motor to rotate. The arc gear is driven by the pitch rotation gear. The antenna assembly is driven by the arc gear and includes an antenna disk. The pitch rotation motor drives the pitch rotation gear, which in turn drives the arc gear to adjust the pitch angle of the antenna disk; the tilting rotation bracket tilts to adjust the tilt angle of the antenna disk.

[0008] In this way, the tilt and pitch angles of the antenna dish can be adjusted separately, which helps to adjust the antenna dish to the optimal angle. Attached Figure Description

Therefore, the first component / part can also be referred to as the second component / part.

[0060] Please see Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A perspective schematic diagram of a dual-axis rotating antenna structure 1000 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 1000 in this embodiment. Figure 3 Draw Figure 1 A side view of the dual-axis rotating antenna structure 1000 of the embodiment. The dual-axis rotating antenna structure 1000 includes a tilting rotation mechanism 1100 and an antenna module 1200.

[0061] The yaw rotation mechanism 1100 includes a yaw rotation bracket 1110. The antenna module 1200 includes a pitch rotation assembly 1220 and an antenna assembly 1210. The pitch rotation assembly 1220 includes a pitch rotation bracket 1221, which is movably mounted on the yaw rotation bracket 1110 and pitches relative to it. The antenna assembly 1210 is mounted on the pitch rotation bracket 1221 and includes an antenna dish 1211. The yaw rotation bracket 1110 and the pitch rotation bracket 1221 drive the antenna dish 1211 to yaw and pitch, thereby adjusting a yaw angle β of the antenna dish 1211 (shown in the diagram). Figure 4 ) and a pitch angle θ.

[0062] In this way, the yaw angle β and the pitch angle θ of the antenna dish 1211 can be adjusted separately, which helps to adjust the antenna dish 1211 to the optimal receiving angle.

[0063] The dual-axis rotating antenna structure 1000 may further include a base 1300, and a tilting rotating bracket 1110 is movably disposed on the base 1300 and tilts relative to the base 1300. The tilting rotating bracket 1110 may include a base plate 1112 and two arms 1111, the two arms 1111 being spaced apart and protruding from the base plate 1112, and an elevation rotating bracket 1221 being pivotally connected between the two arms 1111.

[0064] Specifically, the base 1300 is generally disc-shaped and includes a central gear 1310. The central gear 1310 includes a gear hole. The body of the base 1300 and the central gear 1310 can be integrally molded using plastic parts. The dual-axis rotating antenna structure 1000 may also include a control circuit board 1400 and a heat sink 1500, with the control circuit board 1400 and the heat sink 1500 located below the base 1300.

[0065] The yaw rotation bracket 1110 may further include a limiting protrusion 1116, which protrudes from the lower surface of the base plate 1112 facing the base 1300 and is pivotally mounted in the gear hole, allowing the yaw rotation bracket 1110 to yaw relative to the base 1300, that is, to rotate in the X-axis and Y-axis planes. The base plate 1112 is elongated and includes two arcuate edges and two straight edges, with each support arm 1111 having an isosceles triangular structure and connected to each straight edge. The yaw rotation bracket 1110 may further include a groove 1113 and a through hole 1114, the groove 1113 being located on the base plate 1112 and extending inward from one of the arcuate edges of the base plate 1112, and the through hole 1114 penetrating the base plate 1112 and located next to the groove 1113.

[0066] Please see Figure 4 See also Figures 1 to 3 ,in Figure 4 Draw Figure 3 The embodiment shows a top cross-sectional view of the dual-axis rotating antenna structure 1000 along section line 4-4. The tilting rotation mechanism 1100 may further include a tilting rotation drive gear 1120 and a tilting rotation transmission gear 1130. The tilting rotation drive gear 1120 is disposed between the base plate 1112 and the base 1300, and the tilting rotation transmission gear 1130 meshes between the tilting rotation drive gear 1120 and the central gear 1310. The tilting rotation drive gear 1120 is driven to move along a circumferential direction R1 of the central gear 1310. The tilting rotation mechanism 1100 may further include a tilting rotation motor 1150, which is disposed on the base plate 1112 and drives the tilting rotation drive gear 1120.

[0067] like Figures 1 to 4 As shown, the yaw rotation motor 1150 is mounted on the base plate 1112 and protrudes towards the base 1300 through the through hole 1114. The yaw rotation drive gear 1120 is connected to the drive shaft of the yaw rotation motor 1150 and can be driven to rotate by the yaw rotation motor 1150. The yaw rotation transmission gear 1130 is pivotally mounted on the base plate 1112, and because it meshes with both the yaw rotation drive gear 1120 and the central gear 1310, when the yaw rotation drive gear 1120 rotates, it can drive the yaw rotation transmission gear 1130, causing the yaw rotation transmission gear 1130 to rotate relative to the central gear 1310, thereby driving the yaw rotation bracket 1110 to move along the circumferential direction R1 of the central gear 1310, thus performing yaw. It should be particularly noted here that, in Figure 1 In this configuration, the antenna dish 1211 is oriented parallel to the Y-axis, and the yaw angle β can be considered as 0 degrees. Figure 4 In the middle, the swaying rotating bracket 1110 has swayed clockwise, so that the sway angle β of the antenna dish 1211 is not 0 degrees.

[0068] Furthermore, the oscillating rotation mechanism 1100 may also include a plurality of rotating wheels 1140, which are pivotally mounted at intervals on a lower surface of the base plate 1112 and in contact with the base 1300. For example... Figure 2 and Figure 4 As shown, there are three rotating wheels 1140. The oscillating rotation support 1110 may also include three pivots 1115, which are spaced apart on the lower surface of the base plate 1112, and each rotating wheel 1140 is pivotally mounted on its respective pivot 1115. In this way, each rotating wheel 1140 provides rotational support, preventing the base plate 1112 from deforming due to gravity. Furthermore, the rotating wheels 1140 improve the smoothness of rotation of the oscillating rotation support 1110 relative to the base 1300 and can replace bearings, thus reducing costs.

[0069] The pitch rotation bracket 1221 may include a support frame 1221a and an arc-shaped gear 1221b. The support frame 1221a is pivotally connected to the two arms 1111 and locked to the antenna assembly 1210. The arc-shaped gear 1221b protrudes from the middle section of the support frame 1221a. The pitch rotation assembly 1220 may also include a pitch rotation motor 1224 and a pitch rotation gear 1222. The pitch rotation motor 1224 is disposed on the base plate 1112. The pitch rotation gear 1222 meshes with the arc-shaped gear 1221b and is driven by the pitch rotation motor 1224.

[0070] Support frame 1221a uses two pivot points CR (drawn at...) Figure 5The support frame 1221a may include a main body and two swing arms, which are connected to the two sides of the main body and each swing arm is pivotally connected to the respective support arm 1111. The pivot point CR is located on the swing arm, and the two pivot points CR form a pitch axis X1. The arc-shaped gear 1221b protrudes from the main body in a direction orthogonal to the pitch axis X1. It should be noted that when the pitch axis X1 is parallel to the X-axis, the arc-shaped gear 1221b is located in the Y-axis and Z-axis planes.

[0071] In this embodiment, the support frame 1221a and the arc-shaped gear 1221b are made of plastic, and are integrally molded. Therefore, by using a single-piece molding process with plastic parts, a cost advantage can be achieved compared to disassembling parts (using transmission gears and interlocking plastic parts without gears), while also reducing interference with signal reception.

[0072] The pitch rotation assembly 1220 may further include a fixing member 1223, which is disposed on the base plate 1112 and has a motor hole. The pitch rotation motor 1224 can pass through the motor hole, and the axis of the pitch rotation motor 1224 is parallel to the pitch axis X1. The pitch rotation gear 1222 is connected to the drive shaft of the pitch rotation motor 1224, and its position corresponds to the groove 1113. Therefore, the groove 1113 can form a clearance space for the pitch rotation motor 1224 to protrude into.

[0073] The pitch rotation motor 1224 drives the pitch rotation gear 1222 to rotate, which in turn drives the arc-shaped gear 1221b meshing with it. This causes the pitch rotation support 1221 to pitch around the pivot point CR. It should be noted that the line connecting the pivot point CR and the center point of the pitch rotation gear 1222 on the Y-axis and Z-axis planes can form a 45-degree angle with the Y-axis. This allows the pitch rotation support 1221 to rotate ±45 degrees, thus allowing the pitch angle θ to be between 0 and 90 degrees. However, in other embodiments, the pitch angle can be adjusted as needed and is not limited to this.

[0074] The antenna assembly 1210 may further include an antenna bracket 1212 and a heat sink 1213. The antenna bracket 1212 is connected to the antenna dish 1211 and includes two pins 1212a. The heat sink 1213 includes an arc block 1213a and two connecting portions 1213b. The arc block 1213a includes a flat surface for mounting an antenna circuit board thereon, and the two connecting portions 1213b protrude from one side of the arc block 1213a. During assembly, the arms of the support frame 1221a can be locked to the sides of the connecting portions 1213b first, and then the pins 1212a can be locked to the end of the connecting portion 1213b away from the arc block 1213a, thus connecting the antenna assembly 1210 and the pitch and rotation bracket 1221. The pitch rotation bracket 1221 is then pivotally connected to the two arms 1111 of the yaw rotation bracket 1110. In this way, the yaw rotation mechanism 1100 can be controlled by the control circuit board 1400 to drive the antenna dish 1211 to adjust the yaw angle β, and the pitch rotation assembly 1220 can be controlled to drive the antenna dish 1211 to adjust the pitch angle θ. This can further achieve the effect of driving the antenna dish 1211 to spin to automatically search for the best signal angle.

[0075] It should be noted that in other embodiments, the antenna support may include a pivot portion pivotally connected to the tilting rotation support, and the arc-shaped gear may be directly connected to the antenna support. In this way, the pitch rotation motor and the pitch rotation gear can drive the arc-shaped gear to directly drive the antenna assembly to pivot, which is not limited to the above.

[0076] Please see Figure 5 See also Figures 1 to 4 ,in Figure 5 Draw Figure 1 A side view of the antenna assembly 1210 and the elevation rotation bracket 1221 of the dual-axis rotating antenna structure 1000 of the embodiment. The antenna assembly 1210 and the elevation rotation bracket 1221 are projected onto a virtual orthogonal plane orthogonal to the elevation axis X1 to form an outer contour. There is a maximum distance Dc between two points p1 and p2 on the outer contour. The center of gravity of the antenna assembly 1210 and the elevation rotation bracket 1221 is projected onto the virtual orthogonal plane to form a center of gravity point CG. There is a center of gravity distance Rcg between the center of gravity point CG and the elevation axis X1 on the virtual orthogonal plane. The maximum distance Dc and the center of gravity distance Rcg satisfy the relationship Rcg / Dc≤0.375.

[0077] Specifically, the virtual orthogonal plane is the Y-axis and Z-axis plane, and the outer contour refers to the projected outer contour of the antenna dish 1211, antenna support 1212, heat sink 1213, and elevation / rotation support 1221. There will be multiple points relative to each other on the outer contour. We can find two points p1 and p2, where the distance between the line connecting these two points p1 and p2 on the virtual orthogonal plane is longer than the distance between any other two relative points on the virtual orthogonal plane, and this distance can be defined as the farthest distance Dc. Using the farthest distance Dc between these two points p1 and p2 as the diameter, and the midpoint of the line connecting these two points p1 and p2 as the center, we can draw a virtual circle C1. This virtual circle C1 encompasses the outer contour, and the two points p1 and p2 lie on the virtual circle C1.

[0078] The center of gravity refers to the center of gravity of the antenna dish 1211, antenna bracket 1212, heat sink 1213, and elevation rotation bracket 1221. This center of gravity, when projected onto the virtual orthogonal plane, will also form a point, which is the center of gravity point CG. When configuring the dimensions of the elevation rotation bracket 1221, the distance from the furthest point Dc to the center of gravity Rcg can be considered, ensuring that Rcg / Dc ≤ 0.375.

[0079] In this invention, because the tiny transmission structure inside the pitch-rotation motor 1224 is not very shock-resistant, the impact force transmitted to the pitch-rotation motor 1224 should be reduced to avoid damage to it. Therefore, the center of gravity of the oscillating components (antenna assembly 1210 and pitch rotation bracket 1221) that will pitch and oscillate should be as close as possible to the pivot point CR. In this case, the torque experienced by the pitch-rotation motor 1224 is only the spin torque of the oscillating components, which is equal to the moment of inertia of the oscillating components multiplied by the angular acceleration caused by the impact force. Since the impact force is applied directly to the pivot point CR, and the pivot point CR is a fixed fulcrum, the torque effect generated by the impact force is canceled out and will not damage the pitch-rotation motor 1224.

[0080] Furthermore, if the center of gravity of the oscillating object is as close as possible to the pivot point CR, gravity can be absorbed by the pivot point CR without generating a torque effect on the pitch motor 1224. Conversely, if the distance between the center of gravity and the pivot point CR is increased, when the oscillating object rotates and tilts, a gravitational torque will be applied to the pitch motor 1224, and the greater the tilt, the greater the torque borne by the pitch motor 1224. If a high-specification pitch motor 1224 is configured to withstand a larger torque, it will lead to increased costs. Therefore, the present invention is configured so that the center of gravity is as close as possible to the pivot point CR, allowing the use of a lower-specification pitch motor 1224.

[0081] Furthermore, if the center of gravity is as close as possible to the pivot point CR, it means the centroid is close to the pivot point CR, thus minimizing the radius of rotation required to occupy space. Conversely, if the pivot point CR is far from the centroid, the radius of rotation will increase, leading to an increase in the product's volume.

[0082] Therefore, by projecting the center of gravity and outer contour of the antenna dish 1211, antenna bracket 1212, heat sink 1213, and pitch rotation bracket 1221 onto a virtual orthogonal plane, and ensuring that the distance from the furthest point Dc to the center of gravity Rcg satisfies the relationship Rcg / Dc≤0.375, it means that the center of gravity is as close as possible to the pivot point CR, thereby achieving the aforementioned beneficial effects of reducing impact force, using a lower specification pitch rotation motor 1224, and reducing product size.

[0083] As can be seen from the above embodiments, the present invention has the following advantages: 1. By controlling the yaw rotation mechanism via the circuit board to adjust the yaw angle of the antenna dish, and controlling the pitch rotation component to adjust the pitch angle of the antenna dish, the product can have the ability to search for the best signal location on its own. In addition to saving manpower, it can also enable the product to adapt to a signal field that changes over time, rather than a fixed receiving angle; 2. The main body of the base and the central gear are integrally molded from plastic parts, which has a cost advantage compared to disassembling parts; 3. The support frame and the arc-shaped gear of the pitch rotation bracket are integrally molded from plastic parts, which has a cost advantage compared to disassembling parts; 4. The rotating wheel has a rotational support function, can rotate around the center and functions as a bearing, and can replace bearings, which has a cost advantage; and 5. By considering the relationship between the furthest distance and the center of gravity, the impact force can be reduced, a lower specification pitch rotation motor can be used, and the product size can be reduced.

[0084] 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.
