[0017] Reference Figure 1 According to an embodiment of the utility model, a phase adjustment device for a spotlight antenna comprises: an antenna housing 1, a shielding film 2, a radiation unit 3 and a moving device 4.

The two ends of each shielding film 2 are respectively fixed in one of the phase adjustment channels 11, and a radiation unit 3 is fixed on one side surface of each shielding film 2. Each radiation unit 3 is movably arranged in one of the phase adjustment channels 11. The moving device 4 is respectively connected to each radiation unit 3. When the moving device 4 is started, the moving device 4 drives each radiation unit 3 to move in the corresponding phase adjustment channel 11. Specifically, the position direction of each phase adjustment channel 11 is different, one of the phase adjustment channels 11 is biased to one side of the antenna housing 1, and the other of the phase adjustment channels 11 is biased to the other side of the antenna housing 1, and the farthest distance between the end of each phase adjustment channel 11 and the edge of the antenna housing 1 is equal, and the shortest distance between the end of each phase adjustment channel 11 and the edge of the antenna housing 1 is also equal.
[0018] Specifically, the moving device 4 includes: a mounting seat 41, a first screw rod 42, a second screw rod 43, a plurality of transmission rods 44 and a motor 45. The mounting seat 41 is vertically fixed on the surface of the antenna housing 1, the mounting seat 41 and the motor 45 are arranged opposite to each other, and the mounting seat 41 and the motor 45 are both located between the two phase adjustment channels 11. The first screw rod 42 and the second screw rod 43 are parallel to each other, and the first screw rod 42 and the second screw rod 43 are respectively fixedly connected to the rotating part in the motor 45, so as to rotate relative to the mounting seat 41 after the motor 45 is started. One end of each transmission rod 44 is movably arranged on one of the first screw rod 42 or the second screw rod 43, and the other end of each transmission rod 44 is fixedly connected to a radiation unit 3. When the motor 45 is started, the first screw rod 42 and the second screw rod 43 respectively drive the corresponding transmission rod 44 to move, thereby driving the corresponding radiation unit 3 to move. In this embodiment, one end of each transmission rod 44 is bent and fixedly connected to a radiation unit 3, and the other end of each transmission rod 44 is movably disposed on one of the first screw rod 42 or the second screw rod 43 through a threaded ring 5. Each threaded ring 5 is provided with a thread matching the first screw rod 42 or the second screw rod 43.
[0019] Furthermore, in order to enable each radiation unit 3 to move smoothly in the corresponding phase adjustment channel 11, in the present embodiment, a plurality of track arms 12 and a plurality of tracks 13 are further provided on the surface of the antenna cover 1. Each track arm 12 is distributed along the edge of the corresponding phase adjustment channel 11, and a guide hole for the track 13 to pass through is provided on the surface of each track arm 12. At the same phase adjustment channel 11, the guide holes on the track arms 12 on the same side of the phase adjustment channel 11 are aligned one by one. In the present embodiment, four track arms 12 and two tracks 13 are provided at one phase adjustment channel 11. Each track arm 12 is respectively located at the four corners of the phase adjustment channel 11, and the guide holes on the track arms 12 on the same side pass through the same track 13.
[0020] Figure 2 It is a three-dimensional structural schematic diagram of another side of a phase adjustment device for a spotlight antenna according to an embodiment of the utility model.
[0021] Refer to Figure 1 and Figure 2Specifically, each radiation unit 3 includes: a base 31, a sub-slot plate 32 and a plurality of connecting arms 33. The base 31 and the sub-slot plate 32 are respectively arranged on two opposite surfaces of the phase adjustment channel 11, and the surface of the sub-slot plate 32 is fixedly connected to one end of the transmission rod 44. The two ends of the shielding membrane 2 are respectively fixed at the two ends of the phase adjustment channel 11. When the base 31 and the sub-slot plate 32 are fixedly connected by a connecting piece, the shielding membrane 2 is fixed between the base 31 and the sub-slot plate 32. The connecting arm 33 is arranged along the edge of the sub-slot plate 32, and each connecting arm 33 matches the track arm 12 on the same side. Each track 13 passes through the connecting arm 33 and the track arm 12 on the same side at the same time. When the motor 45 is started, the transmission rod 44 drives the sub-slot plate 32 to move on the track 13, thereby performing phase adjustment.
[0022] Furthermore, the shielding film 2 includes a first portion 21 and a second portion 22 which are stacked and fixed. One end of the first portion 21 is fixedly arranged on the inner wall of one end of the phase-adjusting channel 11, and the other end of the first portion 21 is fixedly connected to one end of the second portion 22. The other end of the second portion 22 is fixedly arranged on the inner wall of the other end of the phase-adjusting channel 11. The auxiliary slot plate 32 is fixedly arranged on the side of the second portion 22 facing the outside of the phase-adjusting channel 11, and the first portion 21 and the second portion 22 are both films made of elastic material. After the shielding film 2 is installed, the shielding film 2 shields the area of the phase-adjusting channel 11, thereby reflecting the antenna signal received from the outside.
[0023] When the motor 45 is started, the first screw rod 42 and the second screw rod 43 rotate simultaneously, thereby driving the corresponding transmission rod 44 to move, and then the corresponding radiation unit 3 moves toward or relative to each other in the phase adjustment channel 11. In this process, one of the first part 21 and the second part 22 of the shielding film 2 at each phase adjustment channel 11 is stretched, and the other of the first part 21 and the second part 22 of the shielding film 2 at the corresponding phase adjustment channel 11 is folded, so as to maintain the shielding effect of the shielding film 2 on the phase adjustment channel 11. When the two radiation units 3 move toward each other, the beam width of the entire spotlight antenna decreases. When the two radiation units 3 move relative to each other, the beam width of the entire spotlight antenna increases, and the horizontal beam width remains unchanged at 35°. Among them, the vertical adjustment range of the beam width in the present application is between 35° and 65°. When the two radiation units 3 move relative to each other to the limit distance, the vertical beam width of the entire spotlight antenna is 65°, and when the two radiation units 3 move toward each other to the limit, the vertical beam width of the entire spotlight antenna is 35°.
[0024] In summary, the utility model changes the relative positions of the two radiation units through the moving device while keeping the distance between the two radiation units unchanged, thereby quickly adjusting the beam width of the entire spotlight antenna.
