Description

Technical Field

[0001] The utility model relates to the technical field of antennas, in particular to a lens antenna with adjustable radiation direction. Background Art

[0002] In order to achieve horizontal adjustment of the feed position, the applicant previously applied for a Chinese utility model patent with publication number CN220209261U and patent name "A lens antenna with horizontally adjustable radiation direction". This solution adopts a pushing mechanism composed of a main pushing seat and a secondary pushing seat. When the main pushing seat moves vertically up and down, the pushing roller on the main pushing seat cooperates with the pushing hole on the secondary pushing seat to make the secondary pushing seat move horizontally left and right. At the same time, the secondary pushing seat moves, and the connecting rod can drive the reflector plate of the antenna group to move horizontally left and right around the electromagnetic wave lens, so that the signal radiation direction of the feed source on the reflector plate is also adjusted horizontally left and right. Due to the large number of parts in this solution, the production cost of this solution is high, which is not conducive to application in large-scale laying scenarios. Utility Model Content

DETAILED DESCRIPTION

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figures 1 to 4 A lens antenna with adjustable radiation direction according to embodiment 1, comprising a substrate 1, a driving mechanism 2 and an antenna assembly 3;

[0034] One side of the substrate 1 is a mounting surface, which is a reference surface perpendicular to or at an angle to a horizontal plane when in use;

[0035] The antenna assembly 3 includes an electromagnetic wave lens 31, a feed source 32, and a reflector 33; the electromagnetic wave lens 31 is mounted on a mounting surface; the reflector 33 is slidably mounted on the mounting surface, the reflector 33 being located between the electromagnetic wave lens 31 and the substrate 1, with a sliding track of the reflector 33 arranged around the electromagnetic wave lens 31, the reflective surface of the reflector 33 facing the electromagnetic wave lens 31, and a transmission roller 331 formed on the reflector 33; the feed source 32 is mounted on the reflective surface of the reflector 33, with the signal transmission and reception direction of the feed source 32 being set toward the electromagnetic wave lens 31;

[0036] The pushing mechanism 2 includes a pushing seat 21, which is slidably mounted on the mounting surface. The pushing seat 21 is located between the reflective plate 33 and the substrate 1. A pushing hole 211 is formed on the pushing seat 21. The pushing hole 211 is an elongated hole. The sliding direction of the pushing seat 21 and the length direction of the pushing hole 211 are both parallel to the mounting surface. The sliding direction of the pushing seat 21 is perpendicular to the sliding direction of the reflective plate 33. The sliding direction of the pushing seat 21, the length direction of the pushing hole 211, and the sliding direction of the reflective plate 33 are projected on the mounting surface at an intersecting angle. The angle formed by the length direction of the pushing hole 211 and the projection of the sliding direction of the pushing seat 21 on the mounting surface, and the angle formed by the length direction of the pushing hole 211 and the projection of the sliding direction of the reflective plate 33 on the mounting surface are both 45°; one end of the transmission roller 331 on the reflective plate 33 extends into and is slidably disposed in the pushing hole 211 of the pushing seat 21, so that the pushing seat 21 can drive the reflective plate 33 to slide by sliding;

[0037] A connector 12 electrically connected to the feed source 32 is provided on the substrate 1 below the antenna assembly 3 .

[0038] The working principle of this embodiment is as follows:

[0039] During use, the pusher 21 slides vertically up and down. The push holes 211 on the pusher 21 cooperate with the drive rollers 331 on the reflector 33, allowing the reflector 33 to slide horizontally left and right, driven by the pusher 21. This causes the signal radiation direction of the feed source 32 on the reflector 33 to move horizontally left and right, thereby achieving horizontal adjustment of the radiation direction. By forming the drive rollers 331 on the reflector 33, the reflector 33 can be connected to the pusher 21 without the need for additional transmission components. This simplifies the transmission structure between the reflector 33 and the pusher 21, reduces the number of components in this solution, and thus reduces production costs, making it suitable for large-scale installations.

[0040] like Figures 2 to 4 As shown, the number of the pushing mechanism 2 is one and only one, and the pushing seat 21 of the pushing mechanism 2 is formed with four pushing holes 211, and the four pushing holes 211 are arranged in sequence along the sliding direction of the pushing seat 21; the number of the antenna groups 3 is two, and the two antenna groups 3 are arranged in sequence along the sliding direction of the pushing seat 21; one of the antenna groups 3 includes eight feed sources 32, two electromagnetic wave lenses 31 and one reflecting plate 33, and the eight feed sources 32 are all arranged on the reflecting plate 33, of which four feed sources 32 and one electromagnetic wave lens 31 together with the reflecting plate 33 constitute an antenna unit, and the remaining feed sources 32 and electromagnetic wave lenses 31 together with the reflecting plate 33 constitute an antenna unit. Another antenna unit is formed, with the two antenna units sharing the same reflector 33. Two drive rollers 331 are formed on the reflector 33 of this antenna group 3. Another antenna group 3 includes only one antenna unit, which is composed of three feed sources 32, an electromagnetic wave lens 31, and a reflector 33. Two drive rollers 331 are formed on the reflector 33 of this antenna group 3. The four drive rollers 331 of the two antenna groups 3 extend into and slide in the four push holes 211 on the push seat 21 of the push mechanism 2, respectively. This allows the reflectors 33 of all antenna groups 3 to be simultaneously driven by the push seat 21 of the push mechanism 2 and slide synchronously. This design allows the two antenna groups 3 to be adjusted synchronously using only a single push mechanism 2, making the adjustment operation more convenient in scenarios where independent adjustment of the antenna groups 3 is not required.

[0041] like Figure 4 As shown, the pushing mechanism 2 also includes a driving assembly 22, which includes a driving screw 221, a guide rod 222, and a transmission seat 223. The driving screw 221 is rotatably mounted on the mounting surface, and the guide rod 222 is mounted on the mounting surface. The rotation axis of the driving screw 221 and the length direction of the guide rod 222 are parallel to the sliding direction of the pushing seat 21. A screw hole and a guide hole are formed on the transmission seat 223. The transmission seat 223 is threadedly connected to the driving screw 221 through the screw hole. The transmission seat 223 is slidably connected to the guide rod 222 through the guide hole. The transmission seat 223 is connected and fixed to the pushing seat 21, so that the driving screw 221 can drive the pushing seat 21 to slide by rotating. The provision of the driving assembly 22 makes the sliding operation of the pushing seat 21 more convenient.

[0042] like Figures 1 to 4As shown, the drive assembly 22 is positioned near the bottom of the base plate 1. A drive portion 2211 is formed at one end of the drive screw 221 of the drive assembly 22. The drive portion 2211 has a hexagonal drive hole formed therein for engaging with an external wrench to engage and rotate the drive screw 221. This design facilitates adjustment of the position of the push base 21 by the operator, thereby further facilitating adjustment of the radiation direction of the antenna assembly 3.

[0043] like Figures 2 to 4 As shown, two mounting seats 11 are mounted on the mounting surface of the base plate 1. The two mounting seats 11 are arranged in sequence along the sliding direction of the push seat 21. The drive screw 221, guide rod, and transmission seat 223 of the drive assembly 22 are all arranged between the two mounting seats 11. The two ends of the drive screw 221 are rotatably connected to the two mounting seats 11, and the two ends of the guide rod are connected to the two mounting seats 11. The provision of the mounting seats 11 makes the installation between the drive assembly 22 and the base plate 1 more convenient. The two mounting seats 11 also serve to limit the range of motion of the transmission seat 223, preventing it from moving too far.

[0044] like Figures 2 to 4 As shown, each antenna assembly 3 also includes two first guide seats 34 and four first guide pulleys 35. The two first guide seats 34 are mounted on the mounting surface and arranged sequentially along the sliding direction of the pusher seat 21. Each first guide seat 34 has an arcuate slot 341 formed therein. The reflector 33 is positioned between the two first guide seats 34. Two first guide pulleys 35 are rotatably mounted on the upper and lower sides of the reflector 33, respectively. Each first guide pulley 35 is slidably disposed in the arcuate slot 341 of the corresponding first guide seat 34. This structure ensures smooth and stable sliding of the reflector 33 of the antenna assembly 3.

[0045] like Figures 2 to 4 As shown, the pushing mechanism 2 also includes four second guide seats 23 and eight second guide pulleys 24. The four second guide seats 23 are mounted on the mounting surface, with two second guide seats 23 sequentially arranged on the left side of the pushing seat 21 along the sliding direction of the pushing seat 21, and the other two second guide seats 23 sequentially arranged on the right side of the pushing seat 21 along the sliding direction of the pushing seat 21. Guide slots 231 are formed on the second guide seats 23. Four second guide pulleys 24 are rotatably mounted on the left and right sides of the pushing seat 21, respectively. One second guide seat 23 corresponds to two second guide pulleys 24, and the second guide pulleys 24 are slidably disposed in the guide slots 231 of the corresponding second guide seats 23. This structure allows the sliding of the pushing seat 21 to be smoother and more stable.

[0046] like Figure 1 As shown, this embodiment further includes a housing 4, within which the substrate 1, driving mechanism 2, and antenna assembly 3 are mounted. A through-hole is formed on the bottom surface of the housing 4, through which the connector 12 and the driving portion 2211 of the driving screw 221 are exposed. This design prevents direct exposure of the substrate 1, driving mechanism 2, and antenna assembly 3 to the external environment, providing dust protection.

[0047] like Figures 1 to 4 As shown, the pushing mechanism 2 also includes a scale 25. One end of the scale 25 is connected to the pushing base 21, and the other end of the scale 25 extends out of the bottom surface of the housing 4. The scale 25 cooperates with the bottom surface of the housing 4 to determine the position of the pushing base 21. The addition of the scale 25 allows workers to more easily determine the position of the pushing base 21 when adjusting the radiation direction of the antenna assembly 3, making adjustments more convenient.

[0048] Example 2

[0049] like Figures 5 to 8 Embodiment 2 is a lens antenna with adjustable radiation direction. Embodiment 2 differs from Embodiment 1 in that: there are three antenna groups 3 and three driving mechanisms 2, each of which includes only one antenna unit. The driving seats 21 of the three driving mechanisms 2 are arranged vertically in sequence, with the sliding directions of the driving seats 21 of the three driving mechanisms 2 collinear. The driving assemblies 22 of the three driving mechanisms 2 are each disposed between two mounting seats 11 of the base plate 1. The drive rollers 331 on the reflector 33 of one antenna group 3 correspond to the driving holes 211 on the driving seats 21 of a driving mechanism 2, so that the reflector 33 of each antenna group 3 can be individually driven to slide by the driving seats 21 of the corresponding driving mechanism 2. Each driving mechanism 2 further includes a connecting member 26, one end of which is connected to the transmission seat 223 and the other end of which is connected to the driving seat 21, so that the driving screw 221 of the driving mechanism 2 can drive its driving seat 21 to slide by rotation. One end of the scale 25 of each driving mechanism 2 is fixedly connected to its connecting member 26. Compared with embodiment 1, the radiation direction of each antenna group 3 of this embodiment can be independently adjusted by the corresponding driving mechanism 2 to meet the use requirements of different scenarios.
