[0002] The radiation angle of a mobile communication antenna needs to be adjusted according to the change of the main source of the antenna. The method is to adjust the phase of the phase shifter in the mobile antenna, which is also called phase modulation. There are often many phase shifters in a mobile communication antenna, and these phase shifters often need to be adjusted separately. Most of the phase shifters and drive devices on the market are one-to-one. One drive device controls one phase shifter separately. To achieve the separate adjustment of multiple phase shifters, multiple drive devices need to be configured, which not only increases the weight of the antenna, but also increases the cost.

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] An embodiment of the present application discloses an antenna transmission device.

[0039] Reference Figure 1 and Figure 2 , an antenna transmission device, including a fixed frame 1 and at least two phase shifters 2. In this embodiment, the number of phase shifters 2 is four. A mobile driving member 11 and a transmission assembly are arranged on the fixed frame 1. The mobile driving member 11 is a servo motor. The mobile driving member 11 is installed on the fixed frame 1. The driving end of the mobile driving member 11 is connected to the transmission assembly for transmission. The phase shifter 2 is installed on the transmission assembly. The mobile driving member 11 can drive at least one phase shifter 2 to slide along a straight line direction through the transmission assembly. A swing rail assembly and a switching assembly are also arranged on the fixed frame 1. The swing rail assembly and the switching assembly are arranged on the swing rail assembly. A limit member 3 is arranged on the switching assembly. The limit member 3 and the swing rail assembly are slidably matched. The swing rail assembly and the switching assembly can make the limit member 3 approach the matching transmission assembly or move away from the transmission assembly, thereby increasing or decreasing the number of slidable phase shifters 2. When the limit member 3 cooperates with the transmission assembly, the phase shifter 2 is in a slidable state.

[0040] When the phase shifter 2 needs to be moved, the mobile driving component 11 can be started, so that the mobile driving component 11 can make at least one phase shifter 2 slide linearly through the transmission cooperation with the transmission component, so as to achieve the phase adjustment effect. When more phase shifters 2 need to be moved, the swing rail component can be slid on the fixed frame 1, and cooperate with the switching component to drive the limit member 3 to move, so that the limit member 3 is close to the transmission component, and the limit member 3 is matched with the transmission component, thereby increasing the number of slidable phase shifters 2. Therefore, when the mobile driving component 11 is started, more phase shifters 2 can be driven to move, and the number of movement of the phase shifter 2 can be changed, so that the movement number of the phase shifter 2 can be adjusted according to the needs, the flexibility of adjustment is improved, and the accuracy of performing phase adjustment is improved.

[0041] Reference Figure 1 and Figure 2 The transmission assembly includes a rotating cylinder 4, a moving rod 41 and a displacement rod 42. The rotating cylinder 4 is rotatably connected to the fixed frame 1. The rotating cylinder 4 is cylindrical, and an opening is provided at one end of the rotating cylinder 4. The inner wall of the opening of the rotating cylinder 4 is provided with an internal thread. The number of the displacement rod 42 is one. The moving rod 41 and the displacement rod 42 are both round rod-shaped. The total number of the moving rods 41 and the displacement rods 42 is consistent with the number of the phase shifters 2. In this embodiment, the number of the moving rods 41 is three. The moving rod 41 is provided with an external thread. The moving rod 41 is inserted into the opening of the rotating cylinder 4. The moving rod 41 and the rotating cylinder 4 are threadedly matched. The displacement rod 42 is provided with an external thread. The displacement rod 42 is inserted into the opening of the rotating cylinder 4. The displacement rod 42 and the rotating cylinder 4 are threadedly matched. Each moving rod 41 or the displacement rod 42 corresponds to a rotating cylinder 4. The phase shifters 2 are distributed and arranged Installed on the moving rod 41 and the displacement rod 42, the number of phase shifters 2 installed correspondingly on one moving rod 41 or one displacement rod 42 is one, the driving end of the moving driving member 11 is provided with a transmission gear assembly, the rotating cylinder 4 is transmission-matched with the transmission gear assembly, the moving driving member 11 can drive the rotating cylinder 4 to rotate through the transmission gear assembly, the limit member 3 can be inserted into the moving rod 41 and slide relative to the moving rod 41, a fixing sleeve 12 is provided on the fixing frame 1, and a guide member 121 is provided on the outer wall of the fixing sleeve 12, the guide member 121 is in a rectangular block shape, the guide member 121 is slidingly matched with the displacement rod 42, and a guide groove 421 is opened on the side wall of the displacement rod 42, the extension direction of the guide groove 421 is consistent with the extension direction of the displacement rod 42, the guide groove 421 is adapted to the guide member 121, and the guide member 121 is inserted into the guide groove 421.

[0042] When the phase shifter 2 needs to be moved, the moving driving member 11 is started, that is, the rotating cylinder 4 can be rotated through the transmission gear assembly. When the rotating cylinder 4 rotates, a torque is applied to the displacement rod 42, and the displacement rod 42 and the guide member 121 are slidably matched. The guide member 121 plays a guiding and limiting role for the displacement rod 42. Therefore, during the rotation of the rotating cylinder 4, under the action of the threaded fit, the displacement rod 42 can slide linearly along its own extension direction, thereby achieving the effect of sliding of at least one phase shifter 2.

[0043] The transmission gear assembly includes an active rotating gear member 13, an annular gear member 14 and a connecting gear member 15. The active rotating gear member 13 is a spur gear. The active rotating gear member 13 is connected to the driving end of the mobile driving member 11. The annular gear member 14 is in a circular ring shape. The outer side of the annular gear member 14 is in an outer gear ring shape. The inner side of the annular gear member 14 is in an inner gear ring shape. The annular gear member 14 is rotatably connected to the fixed frame 1. The connecting gear member 15 is a spur gear. The connecting gear member 15 is rotatably connected to the fixed frame 1. The number of connecting gear members 15 is the same as that of the mobile driving member 11. The number of phase shifters 2 is consistent, the connecting teeth 15 are distributed in a circle around the center of the ring-covered teeth 14, the active rotating teeth 13 are meshed with the outer side of the ring-covered teeth 14, the ring-covered teeth 14 are arranged on the outer peripheral side of the connecting teeth 15, the ring-covered teeth 14 are meshed with the inner side of the connecting teeth 15, the inner side of the connecting teeth 15 is fixedly connected to the outer side of the rotating cylinder 4, the central axis of the connecting teeth 15 coincides with the central axis of the rotating cylinder 4, and the rotating cylinder 4 is located between the inner side of the ring-covered teeth 14 and the fixed sleeve 12.

[0044] When the phase shifter 2 needs to be moved, the mobile driving member 11 drives the active rotating gear member 13 to rotate, driving the annular gear member 14 to rotate, thereby driving the connecting gear member 15 and the rotating cylinder 4 to rotate through the inner side of the annular gear member 14. Under the action of the threaded cooperation and the guide member 121, the displacement rod 42 slides. When the limit member 3 is inserted into the moving rod 41, the rotating cylinder 4 rotates to make the moving rod 41 slide under the action of the threaded cooperation, so that the moving rod 41 and the displacement rod 42 can achieve the effect of simultaneous movement.

[0045] Reference Figure 1 and Figure 3The fixed sleeve 12 is connected to the fixed frame 1 through a bracket. The fixed sleeve 12 extends along the arc direction. The center of the arc of the fixed sleeve 12 coincides with the center of the ring-covered toothed member 14. An opening is opened at one end of the fixed sleeve 12. The swing rail assembly includes a plurality of moving rails 5. The rotating cylinder 4 is located between the inner side of the ring-covered toothed member 14 and the moving rails 5. The moving rails 5 are in the shape of an arc rod. The curvature of the moving rails 5 is consistent with the curvature of the fixed sleeve 12. The moving rails 5 are inserted into the opening of the fixed sleeve 12. The moving rails 5 slide with the fixed sleeve 12. In coordination, a swing rail driver 16 for driving the movable rail 5 to slide is provided on the fixed frame 1. The swing rail driver 16 is a servo motor. The output shaft of the driving end of the swing rail driver 16 coincides with the center of the circle of the annular gear 14. The driving end of the swing rail driver 16 is connected to a swing rail arm. The end of the swing rail arm away from the swing rail driver 16 is connected to the movable rail 5. The swing rail arm is slidably connected to the fixed frame 1. The swing rail driver 16 can drive the swing rail arm to swing in a circumferential direction. The switching component is arranged on the movable rail 5.

[0046] When it is necessary to increase the movable phase shifter 2, the swing rail driving member 16 can drive the swing rail arm to swing, driving the movable rail 5 to slide, so that the switching assembly and the limit member 3 are close to the rotating cylinder 4 connected to the moving rod 41. The limit member 3 can be inserted into the moving rod 41 through the switching assembly, so that the moving rod 41 and the limit member 3 can form a relative sliding state. In this state, when the mobile driving member 11 drives the connecting tooth member 15 and the rotating cylinder 4 to rotate through transmission, the moving rod 41 moves in a straight line, thereby increasing the number of the slidable phase shifters 2. When the limit member 3 is not inserted into the moving rod 41, the moving rod 41 is in a state of following the rotation of the rotating cylinder 4 and does not slide in a straight line.

[0047] Reference Figure 1 and Figure 3 , the number of movable rails 5 is not less than two, the total number of movable rails 5 and fixed sleeves 12 is consistent with the number of phase shifters 2. In this embodiment, the number of fixed sleeves 12 is one, and the number of movable rails 5 is three. The movable rails 5 are arranged in a layer-by-layer sleeve type with the volume decreasing from the outside to the inside. The adjacent ends of adjacent movable rails 5 are plugged into each other, and the adjacent movable rails 5 are slidably connected to each other. The movable rails 5 can be stored layer by layer by sliding in the arc direction. The outermost movable rail 5 is inserted into the opening of the fixed sleeve 12, and the end of the swing rail arm away from the swing rail driving member 16 is connected to the innermost movable rail 5. The movable rail 5 can be stored in the fixed sleeve 12 by sliding, and the number of switching components arranged on each movable rail 5 is one group.

[0048] When the number of movable phase shifters 2 needs to be increased, the swing rail driver 16 can drive the movable rail 5 to slide, so that the movable rail 5 housed in the fixed sleeve 12 moves outward layer by layer starting from the innermost layer. The switching components and the limit members 3 on the movable rail 5 correspond to the positions of the movable rod 41 one by one, so that the movement number of the phase shifters 2 can be appropriately increased according to the needs. When it is necessary to add one phase shifter 2 to enter a sliding state, it is only necessary to move the innermost movable rail 5. When it is necessary to add two phase shifters 2 to enter a sliding state, it is only necessary to move the innermost movable rail 5 and the second innermost movable rail 5. When all phase shifters 2 need to enter a sliding state, all movable rails 5 can be moved out, and the adjustment flexibility is high.

[0049] Reference Figure 3 and Figure 4 The outer wall of the movable rail 5 is provided with a guide slide 51, and the guide slide 51 is in a dovetail block shape. The inner wall of the movable rail 5 is provided with a guide slide groove 52 for the guide slide 51 on the adjacent movable rail 5 to slide. The guide slide groove 52 extends along the extension direction of the movable rail 5, and the guide slide groove 52 is adapted to the guide slide 51. There is a gap between the guide slide groove 52 and the end surface of the movable rail 5 away from the fixed sleeve 12. Similarly, the inner wall of the fixed sleeve 12 is correspondingly provided with an inner groove for the guide slide 51 to slide.

[0050] When adjacent movable rails 5 move relative to each other, the guide groove 52 and the guide member 51 can play a guiding role to improve the sliding stability. The gap between the guide groove 52 and the end of the movable rail 5 allows the guide member 51 to abut against the groove wall of the guide groove 52 when sliding to the end of the guide groove 52, making it difficult for adjacent movable rails 5 to separate from each other.

[0051] Reference Figure 3 and Figure 5The switching assembly includes a connecting shell 31, a sliding member 32, an elastic member 33, an adsorbing member 34 and an extending adsorbing member 35. The connecting shell 31 is arranged on the outer wall of the movable rail 5. The connecting shell 31 is in a rectangular shell shape. The sliding member 32 is in a rectangular plate shape. The sliding member 32 is slidably connected to the inner wall of the connecting shell 31. The elastic member 33 is a spring. One end of the elastic member 33 is connected to the side of the sliding member 32 away from the rotating cylinder 4. The other end of the elastic member 33 is connected to the side of the inside of the connecting shell 31 away from the rotating cylinder 4. The adsorbing member 34 is an electromagnet (the connection of the electromagnet to electricity is a prior art and is not described in detail). The adsorbing member 34 is installed at the end of the connecting shell 31 away from the rotating cylinder 4. The sliding member 32 is located between the adsorbing member 34 and the movable rail 5. The extending adsorbing member 35 is a metal straight Rod, the extension suction piece 35 is arranged on the side of the sliding piece 32 close to the adsorption piece 34, and the adsorption piece 34 can apply suction to the extension suction piece 35 when the power is on. When the adsorption piece 34 applies suction to the extension suction piece 35, the sliding piece 32 moves toward the direction close to the center of the circle of the ring-covering toothed piece 14, and a through hole for the extension suction piece 35 to pass through is provided at the end of the connecting shell 31 away from the rotating cylinder 4. The limiting piece 3 is in the shape of a rectangular straight rod, and the limiting piece 3 is fixedly connected to the side of the sliding piece 32 away from the extension suction piece 35. The limiting piece 3 passes through the connecting shell 31, and a limiting hole 411 for the limiting piece 3 to be inserted and slided is provided on the side wall of the moving rod 41. The limiting hole 411 is adapted to the limiting piece 3, and the extension direction of the limiting hole 411 is consistent with the length direction of the moving rod 41.

[0052] When it is necessary to switch the moving rod 41 to a sliding state, the adsorption member 34 is energized to make the sliding member 32 move toward the center of the ring-covered tooth member 14, and the elastic member 33 is compressed, driving the limiting member 3 away from the inner wall of the ring-covered tooth member 14, and moving the moving rail 5 close to the moving rod 41 so that the limiting member 3 is aligned with the limiting hole 411. At this time, the adsorption member 34 is powered off, and the sliding member 32 is reset under the elastic force of the elastic member 33, thereby driving the limiting member 3 to move toward the inner wall of the ring-covered tooth member 14, and finally the end of the limiting member 3 is inserted into the limiting hole 411 to form a plug-in state. After insertion, when the rotating cylinder 4 rotates, the moving rod 41 can no longer rotate with the rotating cylinder 4, but slides linearly under the action of the thread of the rotating cylinder 4, thereby completing the switching of the moving rod 41 to a sliding state, which is convenient for adjustment.

[0053] Reference Figure 1 and Figure 2 A blocking frame 122 is provided on the fixed sleeve 12, and the blocking frame 122 is located between the fixed sleeve 12 and the ring-covering tooth member 14. A blocking groove 123 for inserting an end of the limiting member 3 away from the sliding member 32 is opened on the side of the blocking frame 122 away from the ring-covering tooth member 14, and the blocking groove 123 is a rectangular groove, and the blocking groove 123 is adapted to the limiting member 3.

[0054] When the movable rail 5 is in the storage state, the limiting member 3 can be inserted into the blocking groove 123, and the blocking groove 123 can limit the limiting member 3, thereby limiting the connecting shell 31 and the movable rail 5, reducing the situation where the swing rail driving member 16 is mistakenly started and causes the movable rail 5 to move.

[0055] Reference Figure 1 The side wall of the fixed sleeve 12 is connected with a signal transmitter 17 and a signal receiver 18 through a bracket. The signal transmitter 17 is an infrared transmitter, and the signal receiver 18 is an infrared receiver. The transmitting end of the signal transmitter 17 faces the receiving end of the signal receiver 18. The displacement rod 42 is located between the signal transmitter 17 and the signal receiver 18. A signal lamp 19 is provided on the fixed frame 1, and the signal receiver 18 is electrically connected to the signal lamp 19. A support rod 21 is provided at one end of all phase shifters 2 close to the rotating cylinder 4. The phase shifter 2 is connected to the end of the moving rod 41 or the displacement rod 42 through the support rod 21, and the outer diameter of the support rod 21 is smaller than the outer diameter of the moving rod 41 and the displacement rod 42.

[0056] When the displacement rod 42 slides out of the rotating cylinder 4, the displacement rod 42 is blocked between the signal transmitting component 17 and the signal receiving component 18, and the signal receiving component 18 cannot receive the signal transmitted by the signal transmitting component 17. When the number of movable phase shifters 2 needs to be increased, the rotating cylinder 4 is rotated by the ring-covering toothed member 14 to make the displacement rod 42 slide into the rotating cylinder 4, so that the end of the displacement rod 42 is flush with the end of the moving rod 41. In this state, the moving rod 41 is at an angle that is easy to be aligned and inserted by the limiting member 3. At the same time, the support rod 21 is located between the signal transmitting component 17 and the signal receiving component 18, reducing the obstruction to the signal transmitting component 17 and the signal receiving component 18, so that the signal receiving component 18 can receive the signal of the signal transmitting component 17, so that the signal light 19 lights up. At this time, the movable rail 5 can be moved to cooperate with the limiting member 3 and the moving rod 41. When the rotating cylinder 4 is rotated by the ring-covering toothed member 14 again, the moving rod 41 and the displacement rod 42 can be moved synchronously, thereby improving the accuracy of phase modulation and reducing the uneven position of the moving phase shifter 2.

[0057] The embodiment of the present application also discloses an antenna, comprising the above-mentioned antenna transmission device.

[0058] The implementation principle of an antenna transmission device and an antenna in the embodiment of the present application is as follows: when only one phase shifter 2 needs to slide linearly, the mobile driving member 11 drives the rotating cylinder 4 to rotate through the active rotating gear member 13, the annular gear member 14 and the connecting gear member 15, and the displacement rod 42 slides under the action of the guide member 121 and the internal thread of the rotating cylinder 4, thereby realizing the sliding of one phase shifter 2; when the number of slidable phase shifters 2 needs to be increased, the suction member 34 applies suction to the extending suction member 35, so that the sliding member 32 and the limiting member 3 move in the direction close to the center of the annular gear member 14, so that The swing rail driving member 16 drives the movable rail 5 to slide, so that the connecting shell 31 is close to the movable rod 41, and the limit member 3 is aligned with the limit hole 411, and then the adsorption member 34 is powered off, and the sliding member 32 is reset under the elastic force of the elastic member 33, so that the end of the limit member 3 is inserted into the limit hole 411, thereby forming a plug-in state. When the rotating cylinder 4 rotates, the movable rod 41 can slide linearly along its own extension direction under the guidance of the limit member 3, thereby increasing the number of slidable phase shifters 2, and the movement amount of the phase shifter 2 can be adjusted according to needs to improve the accuracy of phase adjustment.

[0059] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
