Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to an antenna shift transmission device. Background Art

[0002] In the field of mobile communications, it is necessary to use an antenna transmission mechanism to adjust the radiation angle of the antenna to change the downtilt angle of the antenna.

[0003] In traditional phase shifter transmission devices, most of them are one-to-one, with one motor controlling one phase shifter. When multiple phase shifters need to be adjusted separately, multiple motors need to be configured. Since the motors are expensive and heavy, not only does it make the antenna bulky, but it also increases the cost. There are also disadvantages such as complex structure, difficult production, and high cost.

[0004] Of course, a few existing antennas also use a single power input shift transmission mechanism, and most of the single power input shift transmission mechanisms are circular array designs, occupying a large vertical space and complex control logic. Occasionally, a reciprocating screw is used to achieve single power input shifting, but the reciprocating screw has problems such as high processing cost and difficulty in mold opening.

[0005] Therefore, how to improve the technical defects existing in the prior art has always been a problem that ordinary technicians in this field need to solve urgently. Utility Model Content

[0050] 2. The present application realizes the two functions of shifting and driving of the antenna shift transmission device respectively through the rotation of the power input shaft in two directions: when the power input shaft rotates forward, the first gear can drive the fixed shaft gear to rotate, so that the movable frame moves along the length direction of the driving shaft, thereby pushing the driving gear to slide on the driving shaft, and the driving gear is engaged with different power output gear groups to realize shifting; when the driving gear is engaged with the power output gear group corresponding to the phase shifter whose phase needs to be adjusted, the power input shaft is reversed, and the second gear drives the driving shaft to rotate, thereby driving the driving gear to rotate, and the driving gear drives the power output gear group to operate to realize power output, so as to adjust the phase of the radio frequency signal.

[0071] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0072] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0073] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0074] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0075] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0076] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various devices of the present application are not absolute but relative. These descriptions are appropriate when these devices are in the positions shown in the drawings. If the descriptions of the positions of these devices change, the indications of these directions also change accordingly.

[0077] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0078] According to a specific embodiment provided in this application, see Figure 1 , Figure 2 and Fig.10 , an antenna shift transmission device, including a power component, a drive component and a shift component. The power component is used to provide a power source to realize power input; the drive component is used to output power to drive a phase shifter to change the phase of a radio frequency signal; the shift component is used to change the power output gear so that the drive component can flexibly adjust the corresponding phase shifter as needed.

[0079] For example, the driving assembly includes a driving shaft 210 and a first transmission shaft 230. The driving shaft 210 can rotate under the drive of the power assembly, and at least one driving gear 240 is sleeved on the driving shaft 210. The driving gear 240 can slide along the length direction of the driving shaft 210 and rotate under the action of the driving shaft 210. At least two power output gear sets 250 are connected to the first transmission shaft 230, and each power output gear set 250 can correspond to a phase shifter. The driving gear 240 can be selectively meshed with one of the power output gear sets 250 during the sliding process.

[0080] The shift assembly includes a moving frame 310, which is sleeved on the drive shaft 210, and the moving frame 310 is provided with abutment plates 311 on both sides of the drive gear 240 in the length direction of the drive shaft 210. During the movement process, the moving frame 310 can push the drive gear 240 to move back and forth on the drive shaft 210 through the abutment plates 311 on both sides. Among them, the moving frame 310 is provided with an inner gear ring 320, and the inner gear ring 320 is meshed with a fixed axis gear 330. The power assembly can drive the fixed axis gear 330 to rotate, thereby driving the moving frame 310 to move, and then realizing the sliding of the drive gear 240. Of course, it can be understood that in other embodiments, the moving frame 310 may not be sleeved on the drive shaft 210, as long as it can drive the drive gear 240 to slide along the drive shaft 210. In contrast, in this embodiment, the inner gear ring 320 is sleeved in the moving frame 310, but it is understandable that in other embodiments, the inner gear ring 320 may not be arranged in the moving frame 310, as long as the inner gear ring 320 can drive the moving frame 310 to slide along the axial direction of the driving shaft 210; for example, a waist-shaped groove is arranged on the moving frame 310, and then the moving frame 310 is fixed to the inner gear ring 320 by screws passing through the waist-shaped groove. Such an arrangement allows the moving frame 310 to slide along the axial direction of the driving shaft 210 following the inner gear ring 320, and at the same time facilitates the inner gear ring 320 to slide along the axial direction of the driving shaft 210.

[0081] In the above embodiment, the power assembly can drive the driving shaft 210 and the fixed shaft gear 330 to rotate respectively. Specifically, when the power assembly directly or indirectly drives the fixed shaft gear 330 to rotate, the fixed shaft gear 330 can drive the moving frame 310 to move through the inner gear ring 320 or the rack, and then drive the driving gear 240 to move, so that the driving gear 240 can be meshed with the power output gear set 250 as required. At this time, the power assembly drives the driving shaft 210 to rotate, so that the driving gear 240 on the driving shaft 210 can drive the meshing power output gear set 250 to operate, so as to adjust the corresponding phase shifter, which is convenient to operate and simple in structure.

[0082] More importantly, the present application utilizes the meshing of gears and inner gear ring 320 to achieve gear shifting. Compared with the input gear shift transmission mechanism with a circular array arrangement in the prior art, it occupies a smaller area in the vertical direction, is more conducive to the flattening of the overall structure, and has a simpler control logic. At the same time, compared with the existing input gear shift transmission mechanism using a reciprocating screw, the gears, inner gear ring 320 / rack are obviously easier to produce as standard parts, with lower costs and greater practicality.

[0083] Specifically, the power assembly includes a first power input end and a second power input end, which are used to directly or indirectly drive the fixed axis gear 330 and the drive shaft 210 to rotate. The power assembly may include two motors, one of which is used as the first power input end to drive the fixed axis gear 330 to rotate, and the other is used as the second power input end to drive the drive shaft 210 to rotate.

[0084] Of course, as a preference, see Figures 1 to 3 , the power assembly may also use only one motor 101, that is, the power assembly includes a power input shaft 1011, a first gear 106 and a second gear 110. The power input shaft 1011 is an output shaft on the motor 101, and has two rotation directions, forward and reverse. In this case, the first gear 106 can be used as a first power input end, and the second gear 110 can be used as a second power input end. When the power input shaft 1011 rotates forward, the power input shaft 1011 drives the first gear 106 to rotate, and when it rotates reversely, the power input shaft 1011 drives the second gear 110 to rotate.

[0085] Specifically, the power assembly further includes a shift shaft 105 and a driven shaft 109, and a third gear 103 is connected to the power input shaft 1011, and a first one-way transmission mechanism is provided in the third gear 103, and a shift shaft 105 is inserted in the first one-way transmission mechanism, and the first gear 106 is connected to the end of the shift shaft 105 away from the first one-way transmission mechanism. At the same time, a fourth gear 107 is meshed with the outside of the third gear 103, and a second one-way transmission mechanism is provided in the fourth gear 107, and a driven shaft 109 is inserted in the second one-way transmission mechanism, and the second gear 110 is connected to the end of the driven shaft 109 away from the second one-way transmission mechanism. Among them, the power input shaft 1011 and the shift shaft 105 are connected by a coupling 102, and the coupling is preferably an internal gear coupling 102, which is composed of main parts such as an inner gear ring, a gear shaft 1021 and an end cover.

[0086] When the power input shaft 1011 rotates forward, the power input shaft 1011 can simultaneously drive the shift shaft 105 and the third gear 103 to rotate. At this time, the shift shaft 105 drives the first gear 106 to rotate, and the third gear 103 drives the fourth gear 107 to rotate. The second one-way transmission mechanism can limit the driven shaft 109, so that it cannot rotate with the fourth gear 107, and thus cannot drive the second gear 110 to rotate. Conversely, when the power input shaft 1011 rotates reversely, the power input shaft 1011 can drive the third gear 103 to rotate, and the third gear 103 thereby drives the fourth gear 107 and the driven shaft 109 to rotate, and then drives the second gear 110 to rotate. At the same time, the first one-way transmission mechanism will limit the shift shaft 105, so that it cannot rotate with the third gear 103, and thus cannot drive the first gear 106 to rotate.

[0087] Specifically, the first one-way transmission mechanism includes a first one-way bearing 104, which can only rotate freely in one direction and is locked in the other direction. Therefore, when the power input shaft 1011 rotates forward, the shift shaft 105 is not restricted by the first one-way bearing 104, and the power input shaft 1011 can drive the shift shaft 105 and the third gear 103 to rotate at the same time. Once the power input shaft 1011 is reversed, the first one-way bearing 104 will be locked, thereby limiting the rotation of the shift shaft 105, so that the power input shaft 1011 can only drive the third gear 103 to rotate. Relatively speaking, the second one-way transmission mechanism includes a second one-way bearing 108, which can also only rotate freely in one direction and is locked in the other direction. Therefore, when the power input shaft 1011 rotates forward to drive the shift shaft 105 and the third gear 103 to rotate, the second one-way bearing 108 will be locked and thus limit the rotation of the driven shaft 109. When the power input shaft 1011 reverses and only drives the third gear 103 to rotate, the second one-way bearing 108 no longer restricts the rotation of the driven shaft 109 , and the driven shaft 109 can further drive the second gear 110 to rotate.

[0088] In this embodiment, the power output of the power assembly is split by providing a first one-way bearing 104 and a second one-way bearing 108, and the power input shaft 1011 is rotated in the positive and negative directions (counterclockwise rotation and clockwise rotation) to respectively realize the two functions of shifting and driving of the antenna shift transmission device: when the power input shaft 1011 rotates forward, the first gear 106 can drive the fixed shaft gear 330 to rotate, so that the movable frame 310 moves along the length direction of the driving shaft 210, thereby pushing the driving gear 240 to slide on the driving shaft 210, and the driving gear 240 is engaged with different power output gear sets 250 to realize shifting; when the driving gear 240 is engaged with the power output gear set 250 corresponding to the phase shifter to be adjusted, the power input shaft 1011 is reversed, and the second gear 110 drives the driving shaft 210 to rotate, thereby driving the driving gear 240 to rotate, and the driving gear 240 drives the power output gear set 250 to run, so as to realize power output, so as to adjust the phase shifter.

[0089] Of course, in actual production, in addition to using one-way bearings, a ratchet structure can also be used to achieve one-way transmission. Figure 4 The first one-way transmission mechanism includes a first ratchet 117 and a first pawl 118. The first ratchet 117 is connected to the shift shaft 105, and the outer wall surface of the first ratchet 117 is provided with a plurality of ratchet teeth 119 arranged in sequence along the circumference of the first ratchet 117, and the plurality of ratchet teeth 119 have guide surfaces 120 and limit surfaces 121 at both ends of the circumference of the first ratchet 117. At the same time, the first pawl 118 has two ends, one end is hinged to the third gear 103, and the other end is in contact with the ratchet 119.

[0090] When the power input shaft 1011 rotates forward, the third gear 103 rotates, and the first pawl 118 abuts against the limiting surface 121 on the ratchet teeth 119, thereby driving the first ratchet wheel 117 to rotate with the third gear 103, and then driving the shift shaft 105 to rotate. When the power input shaft 1011 rotates reversely, the first pawl 118 abuts against the guide surface 120, and because the guide surface 120 does not limit the first pawl 118, the first pawl 118 can move relative to the first ratchet wheel 117 along the guide surfaces 120 on the ratchet teeth 119. At this time, the first ratchet wheel 117 does not rotate, and the power input shaft 1011 only drives the third gear 103 to rotate.

[0091] In contrast, the second one-way transmission mechanism includes a second ratchet and a second pawl. The second ratchet is connected to the driven shaft 109, and the outer wall surface of the second ratchet is provided with a plurality of ratchet teeth 119 arranged in sequence along the circumference of the second ratchet. The ratchet teeth 119 have guide surfaces 120 and limit surfaces 121 at both ends of the second ratchet in the circumference. At the same time, the second pawl has two ends, one end is hinged to the fourth gear 107, and the other end is in contact with the ratchet teeth 119. In this way, when the power input shaft 1011 rotates forward to drive the shift shaft 105 and the third gear 103 to rotate, the second pawl moves relative to the second ratchet along the guide surfaces 120 of the plurality of ratchet teeth 119, at which time the second ratchet does not rotate, and the third gear 103 only drives the fourth gear 107 to rotate. When the power input shaft 1011 rotates reversely and only drives the third gear 103 to rotate, the second pawl presses against the limit surface 121, thereby driving the second ratchet to rotate following the fourth gear 107, and then driving the driven shaft 109 to rotate.

[0092] In all the above embodiments, the power input shaft 1011 directly drives the third gear 103 and indirectly drives the first gear 106 and the second gear 110 to rotate. Fig.10 In some embodiments, the power input shaft 1011 may also directly drive the fourth gear 107 to indirectly drive the second gear 110 and the first gear 106 to rotate. No further details will be given here, as they are all within the protection scope of this application.

[0093] See also Figures 2 to 5 , because when the power input shaft 1011 drives the first gear 106 to rotate, the first gear 106 can only rotate in one direction, and at this time, the fixed axis gear 330 connected to the first gear 106 can also only rotate in one direction. In order to realize the reciprocating motion of the driving gear 240, the inner gear ring 320 is provided in the moving frame 310, and the inner gear ring 320 can slide relative to the moving frame 310 in a direction perpendicular to the length of the driving shaft 210. In this way, even if the first gear 106 rotates in one direction, the moving frame 310 can still drive the driving gear 240 to slide in two directions.

[0094] Specifically, see Figure 5 and Figure 6 The inner gear ring 320 has a first meshing surface and a second meshing surface parallel to the drive shaft 210. When the fixed shaft gear 330 meshes with the first meshing surface, the inner gear ring 320 slides with the moving frame 310 in one direction. When the fixed shaft gear 330 is at the edge of the first meshing surface, the fixed shaft gear 330 continues to rotate, and the inner gear ring 320 can slide relative to the moving frame 310 in a direction perpendicular to the length of the drive shaft 210, while the moving frame 310 does not move. When the fixed shaft gear 330 meshes with the second meshing surface, the inner gear ring 320 again moves with the moving frame 310 in the opposite direction to the previous direction, and vice versa.

[0095] In a specific embodiment, see Figure 5 and Figure 7 The antenna shift transmission device further includes a bottom plate 400 for carrying the moving frame 310; at the same time, a first guide groove 420 is provided on the bottom plate 400, and a first guide member that can be inserted into the first guide groove 420 is provided on the side of the inner gear ring 320 facing the bottom plate 400, and the first guide member and the first guide groove 420 cooperate to guide the movement of the inner gear ring 320. In this embodiment, the profile of the first guide groove 420 is in the shape of a runway, which is conducive to the stable movement of the inner gear ring 320, and at the same time, it can also guide the moving frame 310 to move stably along the length direction of the driving shaft 210 to a certain extent, and the structural setting is reasonable and practical.

[0096] Of course, in actual production, the positions of the first guide groove 420 and the first guide member can be interchanged, which helps the inner gear ring 320 to move stably along the preset trajectory. They are not elaborated here one by one and are all within the protection scope of this application.

[0097] Further, in the above embodiments, see Figure 5 and Figure 7 A second guide member 312 is further provided at one end of the movable frame 310 away from the driving shaft 210, and a second guide groove 410 extending along the length direction of the driving shaft 210 is opened on the bottom plate 400 corresponding to the second guide member 312. The second guide member 312 can be movably inserted into the second guide groove 410 to guide the movable frame 310 to move stably along the length direction of the driving shaft 210.

[0098] In this embodiment, the second guide member 312 and the second guide groove 410 are only used to assist in guiding the movement of the movable frame 310 , and the first guide member and the first guide groove 420 are mainly used to simultaneously limit the movement trajectory of the movable frame 310 and the inner gear ring 320 .

[0099] In actual production, the positions of the second guide groove 410 and the second guide member 312 are interchangeable, which helps the movable frame 310 to move stably along the preset trajectory. They are not elaborated here one by one and are all within the protection scope of this application.

[0100] In an exemplary embodiment, the first gear 106 may be directly meshed with the fixed shaft gear 330 , and in this case, the moving frame 310 is disposed perpendicular to the shift shaft 105 .

[0101] Alternatively, see Figure 1 and Figure 2, the shift assembly may further include a fifth gear 340, which is meshed with the first gear 106 and is sleeved on the same fixed axis 350 as the fixed axis gear 330. At this time, the first gear 106 and the fifth gear 340 are both bevel gears, and the angle between the transmission axis of the first gear 106 and the transmission axis of the fifth gear 340 is 90°, so that the moving frame 310 can be arranged parallel to the shift shaft 105. In this way, the shift shaft 105, the moving frame 310, the driving shaft 210 and the first transmission shaft 230 can be arranged flat at the same time, which greatly reduces the space occupied by the antenna shift transmission device in the vertical direction, further improves the flatness of the structure, and the structural setting is reasonable and practical.

[0102] In actual production, the fifth gear 340 and the fixed axis gear 330 can adopt an integrally formed structure, and the two together form a gear structure with one end contracted, which is not limited here and is within the protection scope of this application.

[0103] Specifically, see Figure 1 The power assembly further includes a second transmission shaft 111, which is located on a side of the mobile frame 310 away from the driving shaft 210 and is arranged parallel to the driving shaft 210. At this time, one end of the second transmission shaft 111 is connected to a first transmission gear 112 meshing with the second gear 110, and the first transmission gear 112 and the second gear 110 are both bevel gears, and the transmission axis of the first transmission gear 112 and the transmission axis of the second gear 110 form an angle of 90°; and one end of the second transmission shaft 111 away from the first transmission gear 112 is transmission-connected to the driving shaft 210, so that the second gear 110 drives the driving shaft 210 to rotate.

[0104] Specifically, see Figure 1 and Figure 2 The power assembly can further include a third transmission shaft 114, the two ends of which are respectively connected to a second transmission gear 115 and a third transmission gear 116, and a fourth transmission gear 113 is provided at one end of the second transmission shaft 111 away from the first transmission gear 112. The second transmission gear 115 and the fourth transmission gear 113 are meshed, and both the second transmission gear 115 and the fourth transmission gear 113 are bevel gears, and the angle between the transmission axis of the second transmission gear 115 and the transmission axis of the fourth transmission gear 113 is 90°. Relatively, the end of the drive shaft 210 is connected to a fifth transmission gear 220, and the fifth transmission gear 220 and the third transmission gear 116 are meshed, and both the fifth transmission gear 220 and the third transmission gear 116 are bevel gears, and the angle between the transmission axis of the fifth transmission gear 220 and the transmission axis of the third transmission gear 116 is 90°.

[0105] In this embodiment, the drive shaft 210, the second transmission shaft 111 and the third transmission shaft 114 are all located on the same plane. When the movable frame 310 is arranged parallel to the shift shaft 105, the shift shaft 105, the movable frame 310, the drive shaft 210, the first transmission shaft 230, the second transmission shaft 111 and the third transmission shaft 114 can be arranged flat at the same time, further reducing the space occupied by the antenna shift transmission device in the vertical direction, improving the flatness of the structure, and the structural setting is reasonable and practical.

[0106] Of course, in actual production, the second transmission shaft 111 and the driving shaft 210 may also be connected via a pulley structure, which is not limited here and is within the protection scope of this application.

[0107] In a specific embodiment, see Figure 1 , Figure 2 , Figure 8 and Fig. 9 , each power output gear set 250 includes a first idle gear 251, a second idle gear 252 and a power output gear 254. The first idle gear 251 and the second idle gear 252 are both arranged on the first transmission shaft 230, and the first idle gear 251 and the second idle gear 252 are both connected to the power output gear 254 in a transmission manner, and the power output gear 254 is connected to an external structure, such as a pull rod, a screw rod, etc. of a phase shifter in a transmission manner. When the driving gear 240 is engaged with the first idle gear 251, the driving gear 240 drives the first idle gear 251 to rotate, thereby driving the power output gear 254 to rotate in a first direction a. Conversely, when the driving gear 240 is engaged with the second idle gear 252, the driving gear 240 drives the second idle gear 252 to rotate, thereby driving the power output gear 254 to rotate in a second direction b. In this way, the rotation of the power output gear 254 in two directions is realized, and the antenna shift transmission device can adjust the phase of the corresponding phase shifter clockwise or counterclockwise as needed, which is highly practical.

[0108] Specifically, the power output gear 254 is a bevel gear, and the first idle gear 251 has a steering portion at one end facing the second idle gear 252, the steering portion is in a conical structure, and the small end of the steering portion is arranged toward the second idle gear 252. At the same time, the second idle gear 252 also has a steering portion at one end facing the first idle gear 251, the steering portion is in a conical structure, and the small end of the steering portion is arranged toward the first idle gear 252. The steering portion of the first idle gear 251 and the steering portion of the second idle gear 252 are respectively engaged with different positions of the power output gear 254. When the first idle gear 251 rotates, the power output gear 254 will rotate in the first direction a driven by the steering portion on the first idle gear 251; when the second idle gear 252 rotates, the power output gear 254 will rotate in the second direction b driven by the steering portion on the second idle gear 252.

[0109] In actual production, in addition to providing a steering portion on the first idle gear 251 and the second idle gear 252 , a steering gear 253 may be provided to achieve a transmission connection between the first idle gear 251 , the second idle gear 252 and the power output gear 254 .

[0110] Specifically, see Figure 8 and Fig. 9 Each power output gear set 250 further includes two steering gears 253, both of which are bevel gears and meshed with different positions of the power output gear 254. At the same time, the first idle gear 251 and the second idle gear 252 are respectively arranged on the side away from each other of the two steering gears 253. When the driving gear 240 is meshed with the first idle gear 251, the steering gear 253 close to the first idle gear 251 rotates with the first idle gear 251, thereby driving the power output gear 254 to rotate in the first direction α; when the driving gear 240 is meshed with the second idle gear 252, the steering gear 253 close to the second idle gear 252 rotates with the second idle gear 252, thereby driving the power output gear 254 to rotate in the second direction β.

[0111] As a preference, see Figure 8 and Fig. 9 The driving gear 240 is provided with chamfers at both end surfaces in the length direction of the driving shaft 210, which can reduce the interference between the driving gear 240 and the first idle gear 251, the second idle gear 252, and the steering gear 253 during the sliding process, and can also play a certain guiding role, so that the driving gear 240 can better engage with the first idle gear 251 or the second idle gear 252.

[0112] In this embodiment, the power output gear 254 is not coaxial with the first idle gear 251 and the second idle gear 252. However, it is understood that in other embodiments, the power output gear 254, the first idle gear 251 and the second idle gear 252 can also be coaxially arranged. At this time, the power output gear 254 is located between the first idle gear 251 and the second idle gear 252, and a steering gear 253 is also arranged between the first idle gear 251 and the power output gear 254, so that the first idle gear 251 can drive the power output gear 254 to rotate along the first direction α, and the second idle gear 252 drives the power output gear 254 to rotate along the second direction β. Of course, in other embodiments, the steering gear 253 can also be arranged between the driving gear 240 and the first idle gear 251, so that when the driving gear 240 directly or indirectly drives the first idle gear 251 and the second idle gear 252, the first idle gear 251 and the second idle gear 252 rotate in opposite directions. In other embodiments, the second idle gear 252 may be further omitted. In this case, the first idle gear 251 and the power output gear 254 are installed on the first transmission shaft 230, and a steering gear 253 is provided between the first idle gear 251 and the power output gear 254. In this way, the driving gear 240 can directly drive the power output gear 254 to rotate along the first direction α; and when the driving gear 240 drives the first idle gear 251 to rotate, the first idle gear 251 drives the steering gear 253 to rotate, and the steering gear 253 drives the power output gear 254 to rotate, so that the power output gear 254 can rotate along the second direction β.

[0113] In a specific embodiment, see Figures 10 to 12 , the number of the drive shaft 210 can also be two, namely the first drive shaft 211 and the second drive shaft 212, the first drive shaft 211 and the second drive shaft 212 are arranged in parallel, and the drive gear 240 on the first drive shaft 211 is the first drive gear 241, and the drive gear 240 on the second drive shaft 212 is the second drive gear 242. In this embodiment, the mobile frame 310 is suitable for simultaneously driving the first drive gear 241 and the second drive gear 242 to slide on the first drive shaft 211 and the second drive shaft 212 respectively. Specifically, the first drive shaft 211 is provided with a first meshing gear 260, and the second drive shaft 212 is provided with a second meshing gear meshing with the first meshing gear 260. When the second power input end drives the first drive shaft 211 or the second drive shaft 212 to rotate, the rotation directions of the first drive shaft 211 and the second drive shaft 212 are opposite.

[0114] At this time, each power output gear set 250 may include a first idle gear 251 and a power output gear 254. The first idle gear 251 is disposed on the first transmission shaft 230 and meshes with the power output gear 254. The power output gear 254 is transmission-connected to an external structure, such as a pull rod, a screw rod, etc. of a phase shifter. Thus, when the first driving gear 241 meshes with the first idle gear 251, the first driving gear 241 drives the first idle gear 251 to rotate, and the first idle gear 251 further drives the power output gear 254 to rotate in the first direction α; when the second driving gear 242 meshes with the first idle gear 251, the second driving gear 242 drives the first idle gear 251 to rotate in the opposite direction, and the first idle gear 251 further drives the power output gear 254 to rotate in the second direction β.

[0115] In actual production, the second gear 110 (second power input end) can be connected to the first meshing gear 260 or the second meshing gear through a pulley structure, and can also be connected to the first meshing gear 260 or the second meshing gear through a gear or a gear set. They are not elaborated here one by one, and they are all within the protection scope of this application.

[0116] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0117] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
