Abstract
Description
Technical Field
[0001] This invention relates to the field of communication equipment technology, and in particular to an output mechanism and a base station antenna. Background Technology
[0002] Antenna drive mechanisms are often used to control components such as phase shifters to achieve phase changes, enabling rapid optimization of antenna coverage networks. Currently, the output mechanism of the drive mechanism often uses screw clamps or rack and pinion gears to adjust displacement. Because rack and pinion output mechanisms are compact, easy to install, lower in cost, and occupy less space, more and more antenna manufacturers are adopting this solution.
[0003] However, to prevent jamming during transmission, the rack and pinion output mechanism requires an appropriate tooth backlash, which results in low displacement accuracy. Therefore, a locking mechanism is added to the rack and pinion output mechanism to lock it after displacement to improve its positional accuracy. This often requires an additional power input device, leading to a more complex antenna structure and higher maintenance costs. Summary of the Invention
[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of this invention is to provide an output mechanism with a simple overall structure that enables intermittent movement of the output gear, achieving output from the output sleeve in the first direction. Simultaneously, it utilizes the gap between the transmission component and the output gear when the transmission relationship is disengaged to restore the output sleeve to its initial state, achieving two different power transmission paths for output. This isolates the rotational motion of the output gear from the movement of the output sleeve in the first direction, allowing the output mechanism to achieve two different power transmission paths with only one drive component, reducing the production cost of the output mechanism and the phase shifter.
[0005] The present invention also proposes a base station antenna having the above-mentioned output mechanism.
[0006] An output mechanism according to a first aspect of the present invention includes: a first transmission path including a transmission member and an output gear disposed along a first direction, wherein the transmission member and the output gear are respectively provided with a first transmission protrusion and a second transmission protrusion, the first transmission protrusion having a first surface and a second surface at two end faces in the circumferential direction of the output gear, wherein when the transmission member rotates counterclockwise, the first surface is adapted to abut against the second transmission protrusion, and when the transmission member rotates clockwise, the second surface is adapted to abut against the second transmission protrusion, wherein the second transmission protrusion rotates between the position abutting against the first surface and the position abutting against the second surface. When in motion, the transmission component disengages from the output gear; the second transmission path includes an output sleeve and a limiting assembly. The output sleeve is sleeved on the transmission component. One of the output sleeve and the transmission component has a threaded groove, and the other has a sliding protrusion that passes through the threaded groove. The limiting assembly is located radially outside the output sleeve. One of the limiting assembly and the output sleeve has a limiting protrusion, and the other has a limiting groove extending along a first direction. The limiting protrusion is slidably disposed in the limiting groove. The first direction is parallel to the rotation center line of the transmission component.
[0007] According to the output mechanism of the present invention, by providing a first transmission cam and a second transmission cam that cooperate with each other between the transmission member and the output gear, and by setting the transmission relationship between the transmission member and the output gear to disengage when the second transmission cam rotates between the position of abutting the first surface and the position of abutting the second surface, intermittent motion of the output gear can be realized. By providing a threaded groove and a sliding cam that cooperate with each other between the output sleeve and the transmission member, output of the output sleeve in the first direction can be realized. Simultaneously, the gap when the transmission member and the output gear disengage can be used to restore the output sleeve to its initial state. The overall structure is simple, and it can realize two different power transmission paths for output. The rotational motion of the output gear can be independent of the motion of the output sleeve in the first direction. Furthermore, this design allows the output mechanism to achieve two different force transmission paths with only one drive component, reducing the production cost of the output mechanism. Moreover, it enables the output gear to drive the medium for position adjustment to regulate the phase, meeting the medium position drive requirements of the phase shifter. The output sleeve can be used to lock and unlock the medium, reducing the risk of phase changes due to medium displacement from the preset position. This satisfies the requirement of locking the medium at the preset position, allowing the output unit to be located within the phase shifter to adjust the medium's position. The medium's position adjustment movement can be independent of the locking and unlocking movements, ensuring the reliability of the phase shifter's operation, reducing the number of drive components in the phase shifter, and lowering its production cost.
[0008] According to some embodiments of the present invention, a third transmission protrusion is provided in the threaded groove.

The plurality of second ratchet teeth are spaced apart along the circumference of the output sleeve and are all arranged counterclockwise. Two adjacent second ratchet teeth define the second groove. The limiting protrusion includes a first pawl and a second pawl. The first ratchet teeth and the first pawl are adapted to abut against each other in the counterclockwise direction. The second ratchet teeth and the second pawl are adapted to abut against each other in the clockwise direction. When the sliding protrusion abuts against the third transmission protrusion, the first surface abuts against the second transmission protrusion. The first pawl disengages from the first groove in the first direction, and the second ratchet teeth abut against the second pawl in the clockwise direction.
[0009] In some embodiments of the present invention, a fourth transmission protrusion is provided in the threaded groove.

The second pawl disengages from the second groove in the first direction, and the first pawl abuts against the first ratchet in the counterclockwise direction.
[0010] In some embodiments of the present invention, the limiting groove includes a first groove and a second groove.

These first ratchet teeth are spaced apart circumferentially along the output sleeve and all face counterclockwise. Two adjacent first ratchet teeth define the first groove. The output sleeve also has a plurality of second ratchet teeth arranged radially outward on its outer periphery. These second ratchet teeth are spaced apart from the first ratchet teeth along the first direction. These second ratchet teeth are spaced apart circumferentially along the output sleeve and all face clockwise. Two adjacent second ratchet teeth define the second groove. The output mechanism further includes a first pawl and a second pawl. The first ratchet teeth abut against the first pawl in a clockwise direction, and the second ratchet teeth abut against the second pawl in a counterclockwise direction. When the sliding convex abuts against the third transmission convex, the first pawl disengages from the first groove in the first direction, and the second pawl abuts against the second pawl in a counterclockwise direction. When the sliding convex abuts against the fourth transmission convex, the second pawl disengages from the second groove in the first direction, and the first pawl abuts against the first pawl in a clockwise direction.

[0050] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0051] Please refer to the attached diagram below. Figures 1-18 The output mechanism according to an embodiment of the present invention is described.
[0052] According to a first aspect embodiment of the present invention, an output mechanism 100 includes: a first transmission path and a second transmission path, wherein the first transmission path includes a transmission member 1 and an output gear 2 disposed along a first direction (referring to direction e1 in the drawings), and refers to... Figure 5 , Figure 6 , Figure 9 and Figure 15 The transmission component 1 and the output gear 2 are respectively provided with a first transmission protrusion 11 and a second transmission protrusion 21. The two end faces of the first transmission protrusion 11 on the circumferential direction of the output gear 2 are a first surface 111 and a second surface 112, respectively. When the transmission component 1 rotates counterclockwise, the first surface 111 is adapted to abut against the second transmission protrusion 21. When the transmission component 1 rotates clockwise, the second surface 112 is adapted to abut against the second transmission protrusion 21.
[0053] It should be explained that the rotation direction of the transmission component 1 is related to the viewing direction. The descriptions of the rotation direction of the transmission component 1 in this application, such as "the transmission component 1 rotates counterclockwise" and "the transmission component 1 rotates clockwise", are only for describing two opposite rotation directions of the transmission component 1 and are not particularly limiting.
[0054] When the second transmission protrusion 21 rotates between the position of abutting the first surface 111 and the position of abutting the second surface 112, the transmission member 1 disengages from the transmission relationship with the output gear 2. For example, in the initial state, the second transmission protrusion 21 is located between the first surface 111 and the second surface 112, that is, the second transmission protrusion 21 is not in contact with the first surface 111 and the second transmission protrusion 21 is not in contact with the second surface 112; wherein, when the transmission member 1 rotates counterclockwise, the rotation angle of the second transmission protrusion 21 from the initial position to abutting the first surface 111 is the first rotation angle; when the transmission member 1 rotates clockwise, the rotation angle of the second transmission protrusion 21 from the initial position to abutting the second surface 112 is the second rotation angle.
[0055] When the first surface 111 abuts against the second transmission protrusion 21, the transmission member 1 is rotated clockwise. Before the second transmission protrusion 21 abuts against the second surface 112, the transmission member 1 does not drive the output gear 2 to rotate. The transmission member 1 idles (wherein, the idle angle of the transmission member 1 is the sum of the first rotation angle and the second rotation angle). After the second transmission protrusion 21 abuts against the second surface 112, the transmission member 1 drives the output gear 2 to rotate clockwise through the abutment between the first transmission protrusion 11 and the second transmission protrusion 21.
[0056] When the second surface 112 abuts against the second transmission protrusion 21, the transmission component 1 rotates counterclockwise. Before the second transmission protrusion 21 abuts against the first surface 111, the transmission component 1 does not drive the output gear 2 to rotate. The transmission component 1 idles (wherein, the idle angle of the transmission component 1 is the sum of the first rotation angle and the second rotation angle). After the second transmission protrusion 21 abuts against the first surface 111, the transmission component 1 drives the output gear 2 to rotate counterclockwise through the abutment between the first transmission protrusion 11 and the second transmission protrusion 21.
[0057] Reference Figure 2 , Figure 4 , Figures 9-12 The second transmission path includes an output sleeve 3 and a limiting assembly. The output sleeve 3 is sleeved on the transmission component 1. One of the output sleeve 3 and the transmission component 1 has a threaded groove 31, and the other of the output sleeve 3 and the transmission component 1 has a sliding protrusion 13 that passes through the threaded groove 31. For example, when the output sleeve 3 has a threaded groove 31, the transmission component 1 has a sliding protrusion 13; when the output sleeve 3 has a sliding protrusion 13, the transmission component 1 has a threaded groove 31.
[0058] For example, when the output sleeve 3 is provided with a threaded groove 31, the threaded groove 31 can penetrate the output sleeve 3 radially, or it can not penetrate the output sleeve 3 radially. When the threaded groove 31 does not penetrate the output sleeve 3 radially, the output sleeve 3 can be manufactured by dividing it into two independent parts by a plane passing through its central axis, thereby reducing the manufacturing difficulty and production cost of the output sleeve 3. Specifically, refer to... Figures 10-12 The output sleeve 3 can be assembled from a first cylindrical wall 37 and a second cylindrical wall 38. Anti-misalignment post 371 is provided on the surfaces of the first cylindrical wall 37 and the second cylindrical wall 38 that abut against each other. Anti-misalignment hole 381 is provided on the second cylindrical wall 38. The anti-misalignment post 371 is inserted into the anti-misalignment hole 381, and the distance from the anti-misalignment post 371 to the two ends of the output sleeve 3 in the first direction is different. In this way, the anti-misalignment post 371 and the anti-misalignment hole 381 can play a misalignment role in the assembly of the output sleeve 3, so that the part of the threaded groove 31 located on the first cylindrical wall 37 can be correctly assembled with the part of the threaded groove 31 located on the second cylindrical wall 38, avoiding the risk of discontinuity of the threaded groove 31 caused by assembling the first cylindrical wall 37 opposite to the second cylindrical wall 38, and facilitating the assembly of the output sleeve 3.
[0059] When the transmission component 1 rotates, the transmission component 1 can drive the output sleeve 3 to move in the first direction through the mutual cooperation of the threaded groove 31 and the sliding protrusion 13. It should be understood that regardless of whether the threaded groove 31 is left-handed or right-handed, the transmission component 1 can drive the output sleeve 3 to move in the first direction when it rotates, only the direction of movement of the output sleeve 3 in the first direction is different.
[0060] Reference Figures 4-6 The limiting component is located radially outside the output sleeve 3. One of the limiting component and the output sleeve 3 has a limiting protrusion 41, and the other of the limiting component and the output sleeve 3 has a limiting groove 32 extending along a first direction. The limiting protrusion 41 is slidably disposed in the limiting groove 32. The first direction is parallel to the rotation center line of the transmission member 1. For example, when the limiting component has a limiting protrusion 41, the output sleeve 3 has a limiting groove 32 extending along the first direction; when the limiting component has a limiting groove 32, the output sleeve 3 has a limiting protrusion 41 extending along the first direction.
[0061] The limiting protrusion 41 and the limiting groove 32 cooperate to limit the output sleeve 3 in the circumferential direction of the transmission member 1, preventing the output sleeve 3 from rotating with the transmission member 1. When the transmission member 1 rotates, this allows the transmission member 1 to drive the output sleeve 3 to move in the first direction through the cooperation of the threaded groove 31 and the sliding protrusion 13. For example, the transmission member 1 can drive the output sleeve 3 to move toward the output gear 2 in the first direction when rotating clockwise, that is, the transmission member 1 can drive the output sleeve 3 to move away from the output gear 2 in the first direction when rotating counterclockwise. The transmission member 1 can also drive the output sleeve 3 to move away from the output gear 2 in the first direction when rotating clockwise, that is, the transmission member 1 can drive the output sleeve 3 to move toward the output gear 2 in the first direction when rotating counterclockwise.
[0062] When the first surface 111 abuts against the second transmission protrusion 21, the transmission component 1 is rotated clockwise. Before the second transmission protrusion 21 abuts against the second surface 112, the transmission component 1 has a certain free rotation angle when rotating clockwise (for example, the free rotation angle of the transmission component 1 when rotating clockwise is the second rotation angle). The transmission component 1 can first drive the output sleeve 3 to move in the first direction through the mutual cooperation of the threaded groove 31 and the sliding protrusion 13. After the second transmission protrusion 21 abuts against the second surface 112, the transmission component 1 drives the output gear 2 to rotate clockwise through the abutment between the first transmission protrusion 11 and the second transmission protrusion 21, while maintaining the movement of the output sleeve 3 in the first direction. When the transmission component 1 rotates clockwise to the first preset angle, the transmission component 1 can be rotated counterclockwise. By rotating the first preset angle in the opposite direction, the output sleeve 3 is driven to move in the opposite direction in the first direction, and the output sleeve 3 is adjusted back to the initial state. It should be understood that, in order to prevent the output sleeve 3 from rotating when the transmission component 1 rotates clockwise, the first preset angle should be less than or equal to the sum of the first rotation angle and the second rotation angle.
[0063] Similarly, when the second surface 112 abuts against the second transmission protrusion 21, the transmission component 1 is rotated counterclockwise. Before the second transmission protrusion 21 abuts against the first surface 111, the transmission component 1 has a certain free rotation angle when rotating counterclockwise (for example, the free rotation angle when the transmission component 1 rotates clockwise is the first rotation angle). The transmission component 1 can first drive the output sleeve 3 to move in the first direction through the mutual cooperation of the threaded groove 31 and the sliding protrusion 13. After the second transmission protrusion 21 abuts against the first surface 111, the transmission component 1 drives the output gear 2 to rotate counterclockwise through the abutment between the first transmission protrusion 11 and the second transmission protrusion 21, and at the same time drives the output sleeve 3 to continue moving in the first direction. When the transmission component 1 rotates counterclockwise to the second preset angle, the transmission component 1 can be rotated clockwise. By rotating in the opposite direction by the second preset angle, the output sleeve 3 is driven to move in the opposite direction in the first direction, and the output sleeve 3 is adjusted back to the initial state. It should be understood that, in order to prevent the output sleeve 3 from rotating when the transmission component 1 rotates counterclockwise, the second preset angle should be less than or equal to the sum of the first rotation angle and the second rotation angle.
[0064] This allows for intermittent movement of the output gear 2, while the gap between the transmission component 1 and the output gear 2, which disengages from the transmission relationship, allows the output sleeve 3 to return to its initial state. The overall structure is simple, and it can achieve two different power transmission paths. The rotational motion of the output gear 2 can be independent of the motion of the output sleeve 3 in the first direction, so that the output mechanism 100 can achieve two different power transmission paths with only one drive component, thus reducing the production cost of the output mechanism 100.
[0065] By providing a first transmission protrusion 11 and a second transmission protrusion 21 that cooperate with each other between the transmission component 1 and the output gear 2, and by providing a threaded groove 31 and a sliding protrusion 13 that cooperate with each other between the output sleeve 3 and the transmission component 1, when the transmission component 1 is rotated counterclockwise, the transmission component 1 can drive the output sleeve 3 to move in the first direction, realizing the output of the output sleeve 3 in the first direction. After the transmission component 1 rotates a certain angle, the first surface 111 can stop the second transmission protrusion 21, so that the transmission component 1 drives the output gear 2 to rotate counterclockwise, realizing the rotation output of the output gear 2. After driving the output gear 2 to rotate counterclockwise by a preset angle, the transmission component 1 can be rotated clockwise, driving the output sleeve 3 to move in the opposite direction in the first direction, adjusting the output sleeve 3 to the initial state. When the transmission component 1 rotates between the position of the first stop surface 111 and the position of the second stop surface 112, the transmission component 1 disengages from the transmission relationship with the output gear 2. When the transmission component 1 is rotated clockwise to adjust the output sleeve 3 to the initial state, the transmission component 1 does not drive the output gear 2 to reverse. In this way, the intermittent movement of the output gear 2 can be achieved. At the same time, the gap between the transmission component 1 and the output gear 2 disengaging from the transmission relationship can be used to restore the output sleeve 3 to the initial state. The overall structure is simple and can realize two different power transmission paths. The rotational movement of the output gear 2 can be independent of the movement of the output sleeve 3 in the first direction. This allows the output mechanism 100 to realize two different power transmission paths with only one drive component, reducing the production cost of the output mechanism 100.
[0066] For example, in the initial position, the first rotation angle and the second rotation angle of the second transmission cam 21 can be set to be equal, so that the output gear 2 has a certain output angle in both the forward and reverse directions. For example, in the initial position, the first rotation angle and the second rotation angle of the second transmission cam 21 can be set to be different, so that the output gear 2 has different output angles in both the forward and reverse directions, satisfying the diverse output of the output gear 2; specifically, one of the first rotation angle and the second rotation angle can be set to 0, so that the output gear 2 outputs in only one direction, making the output angle of the output gear 2 larger in that direction.
[0067] For example, the output mechanism 100 can be applied to devices that require position adjustment and position positioning after the position adjustment is completed, such as phase shifters, camera angle adjusters, and vehicle rearview mirror angle adjusters; specifically, refer to Figures 1-4 When the output mechanism 100 is applied in the phase shifter, the output gear 2 can be connected to the medium in the phase shifter through the output rack 51 to drive the medium to move. The output sleeve 3 can lock and unlock the output rack 51 by driving the unlocking rod 6.
[0068] When the output mechanism 100 is applied to a phase shifter and phase adjustment is required, the transmission component 1 can be rotated clockwise (or counterclockwise) to drive the output sleeve 3 to move in the first direction. The output sleeve 3 then drives the unlocking lever 6 to move in the first direction, driving the unlocking area of the unlocking lever 6 to correspond with the output rack 51, thereby unlocking the output gear 2. This continues until the second transmission protrusion 21 abuts against the second surface 112. Afterward, the transmission component 1 drives the output rack 51 to move clockwise via the output gear 2 (or the transmission component 1 drives the output rack 51 to move counterclockwise via the output gear 2). The output rack 51 moves while maintaining the movement of the drive output sleeve 3 in the first direction. When the position of the medium in the first direction is adjusted to the preset position, that is, when the transmission member 1 rotates clockwise to the first preset angle (that is, when the transmission member 1 rotates clockwise to the second preset angle), the transmission member 1 can be rotated in the opposite direction. By rotating in the opposite direction by the first preset angle, the output sleeve 3 is driven to move in the opposite direction in the first direction, and the output sleeve 3 is adjusted back to the initial state. The locking area of the unlocking rod 6 is driven to correspond to the output rack 51, and the output rack 51 is locked, thus completing the phase adjustment.
[0069] For example, when the first rotation angle and the second rotation angle are set to be equal, the unlocking lever 6 has two unlocking areas and one locking area, with the two unlocking areas located on both sides of the locking area in the first direction; when one of the first rotation angle and the second rotation angle is set to 0, the unlocking lever 6 has one unlocking area and one locking area.
[0070] This allows the output gear 2 to drive the medium to adjust its position and regulate the phase, meeting the medium position drive requirements of the phase shifter. The output sleeve 3 can be used to lock and unlock the medium in the first direction, reducing the risk of the medium shifting out of the preset position and causing a change in phase. This satisfies the requirement of locking the medium position at the preset position, allowing the output mechanism 100 to be installed in the phase shifter to adjust the medium position. Furthermore, the medium position adjustment movement can be independent of the locking and unlocking movements of the medium position, ensuring the reliability of the phase shifter operation, reducing the number of drive components in the phase shifter, and lowering the production cost of the phase shifter.
[0071] For example, refer to Figures 1-3 and Figure 14The output mechanism 100 also includes an adapter 7, which includes a meshing part 71 and a plug-in part 72. The meshing part 71 meshes with a gear in the transmission member 1, and the plug-in part 72 is provided with a spline for connecting the output shaft of the drive member, so as to ensure that the drive member can transmit power to the adapter 7, allowing the adapter 7 to drive the transmission member 1 to rotate. Furthermore, by providing an adapter between the drive member and the transmission member 1, the output direction of power can be changed by setting the meshing part 71 and the transmission member 1 as a bevel gear, which facilitates the spatial arrangement of the drive member. Specifically, the drive member can be a drive motor or a rotary cylinder.
[0072] According to the output mechanism 100 of the present invention, by providing a first transmission protrusion 11 and a second transmission protrusion 21 that cooperate with each other between the transmission member 1 and the output gear 2, the transmission relationship between the transmission member 1 and the output gear 2 is set to disengage when the second transmission protrusion 21 rotates between the position of abutting the first surface 111 and the position of abutting the second surface 112, which can realize the intermittent movement of the output gear 2. By providing a threaded groove 31 and a sliding protrusion 13 that cooperate with each other between the output sleeve 3 and the transmission member 1, the output of the output sleeve 3 in the first direction can be realized. At the same time, the output sleeve 3 can be restored to the initial state by utilizing the gap when the transmission member 1 and the output gear 2 disengage from the transmission relationship. The overall structure is simple, and two different power transmission paths can be realized for output. The rotational motion of the output gear 2 can be made independent of the output sleeve 3. In addition to the movement in the first direction, the output mechanism 100 can achieve two different force transmission paths with only one drive element, reducing the production cost of the output mechanism 100. Moreover, the output gear 2 can be used to drive the medium to adjust the position and regulate the phase, meeting the medium position drive requirements of the phase shifter. The output sleeve 3 can be used to lock and unlock the medium, reducing the risk of the medium shifting away from the preset position and causing a change in phase. This meets the requirement of locking the medium position at the preset position, allowing the output mechanism 100 to be installed in the phase shifter to adjust the position of the medium. Furthermore, the position adjustment movement of the medium can be independent of the locking and unlocking movements of the medium position, ensuring the reliability of the phase shifter operation, reducing the number of drive elements in the phase shifter, and lowering the production cost of the phase shifter.
[0073] Reference Figures 10-12 According to some embodiments of the present invention, a third transmission protrusion 33 is provided in the threaded groove 31. When the transmission member 1 rotates counterclockwise, the sliding protrusion 13 is adapted to abut against the third transmission protrusion 33. For example, when the threaded groove 31 is provided on the output sleeve 3 and the threaded groove 31 does not extend to both ends of the output sleeve 3 in the first direction, and when the threaded groove 31 is provided on the transmission member 1 and the threaded groove 31 does not drive the transmission member 1 to both ends of the output sleeve 3 in the first direction, the third transmission protrusion 33 is the sidewall of the threaded groove 31 in its extension direction.
[0074] Reference Figures 4-6 , Figure 10 and Figure 13 The limiting groove 32 includes a first groove 321 and a second groove 322. The output sleeve 3 is provided with a plurality of first ratchet teeth 341 and a plurality of second ratchet teeth 342 on its radial outer periphery. The plurality of first ratchet teeth 341 are arranged at intervals along the circumference of the output sleeve 3, and each first ratchet tooth 341 is arranged in a clockwise direction. Two adjacent first ratchet teeth 341 define the first groove 321. That is, in the clockwise direction, the size of the first ratchet tooth 341 in the radial direction of the output sleeve 3 gradually decreases, that is, in the clockwise direction, the size of the first groove 321 in the radial direction of the output sleeve 3 gradually increases.
[0075] Reference Figures 4-6 , Figure 10 and Figure 13 The second ratchet 342 and the first ratchet 341 are spaced apart along the first direction. Multiple second ratchet 342 are spaced apart along the circumference of the output sleeve 3, and each second ratchet 342 is arranged counterclockwise. Two adjacent second ratchet 342 define the second groove 322. That is, in the counterclockwise direction, the size of the second ratchet 342 in the radial direction of the output sleeve 3 gradually decreases; that is, in the counterclockwise direction, the size of the second groove 322 in the radial direction of the output sleeve 3 gradually increases.
[0076] Reference Figures 4-6 , Figure 10 and Figure 13 The limiting protrusion 41 includes a first pawl 411 and a second pawl 412. The first ratchet 341 and the first pawl 411 are adapted to abut in the counterclockwise direction, and the second ratchet 342 and the second pawl 412 are adapted to abut in the clockwise direction. For example, the second pawl 412 can be located on the side of the first pawl 411 away from the output gear 2. When the sliding protrusion 13 abuts against the third transmission protrusion 33, the first surface 111 abuts against the second transmission protrusion 21, the first pawl 411 disengages from the first groove 321 in the first direction, and the second ratchet 342 abuts against the second pawl 412 in the clockwise direction.
[0077] When the transmission component 1 is rotated counterclockwise, before the second transmission protrusion 21 abuts against the first surface 111, the transmission component 1 can first drive the output sleeve 3 to move in the first direction through the mutual cooperation of the threaded groove 31 and the sliding protrusion 13, and the limiting of the first pawl 411 and the first ratchet 341. The output sleeve 3 is driven to move in the direction from the first pawl 411 to the second pawl 412, gradually reducing the cooperation length between the first pawl 411 and the first groove 321 in the first direction, until the second transmission protrusion 21 abuts against the first surface 111, that is, after the transmission component 1 has rotated by the first rotation angle, the first pawl 41... 1. The first groove 321 is disengaged from the limiting relationship in the circumferential direction of the transmission component 1; since the second pawl 412 and the second ratchet 342 abut in the clockwise direction, when the transmission component 1 rotates counterclockwise, the mutual cooperation between the second pawl 412 and the second ratchet 342 does not limit the output sleeve 3. The transmission component 1 can drive the output gear 2 to rotate counterclockwise through the abutment between the first surface 111 and the second transmission protrusion 21. At the same time, the output sleeve 3 is driven to rotate counterclockwise synchronously with the transmission component 1 through the stop between the sliding fitting protrusion 13 and the third transmission protrusion 33, thus ending the movement of the output sleeve 3 in the first direction.
[0078] When the output gear 2 rotates counterclockwise to the third preset angle, that is, when the transmission component 1 continues to rotate the third preset angle after rotating the first rotation angle in the opposite direction, the transmission component 1 can be rotated clockwise. Since the second pawl 412 and the second ratchet 342 abut in the clockwise direction, the mutual cooperation between the second pawl 412 and the second ratchet 342 can limit the output sleeve 3 in the circumferential direction, restricting the rotation of the output sleeve 3. This allows the transmission component 1 to drive the output sleeve 3 to move in the opposite direction in the first direction through the limiting cooperation between the sliding cam 13 and the spiral groove. When the transmission component 1 rotates the first rotation angle in the opposite direction, the output sleeve 3 can be adjusted back to the initial state.
[0079] By setting two sets of opposite ratchet and pawl structures to limit the output sleeve 3, and setting a third transmission protrusion 33 in the spiral groove to stop the sliding protrusion 13 when the transmission component 1 rotates counterclockwise, the first pawl 411 and the second pawl 412 can take turns limiting the output sleeve 3 in the circumferential direction, effectively ensuring the reliability of the movement of the output sleeve 3 in the first direction, reducing the risk of the limiting component disengaging from the output sleeve 3, and improving the reliability of the output mechanism 100.
[0080] Simultaneously, after the transmission component 1 rotates counterclockwise by a first rotation angle to drive the output sleeve 3 to move in the first direction, the transmission component 1 can drive the output sleeve 3 to rotate, ending the movement of the output sleeve 3 in the first direction. This results in the output sleeve 3 occupying less space in the first direction, allowing the transmission component 1 to adjust the output sleeve 3 back to its initial state by rotating clockwise by a first rotation angle, regardless of how much the transmission component 1 drives the output gear 2 to rotate counterclockwise. This increases the output angle range of the output gear 2 in the counterclockwise direction and improves the overall performance of the output mechanism 100. Applying the output mechanism 100 to a phase shifter allows for a larger phase adjustment range of the medium, enabling a more compact overall structure for the phase shifter.
[0081] For example, the limiting component may also include a second elastic element and a third elastic element. The second elastic element is used to press the first pawl 411 into the first groove 321 in the radial direction of the output sleeve 3 so that the first pawl 411 and the first ratchet 341 can be reliably engaged. The third elastic element is used to press the second pawl 412 into the second groove 322 in the radial direction of the output sleeve 3 so that the second pawl 412 and the second ratchet 342 can be reliably engaged, thereby improving the reliability of the output mechanism 100.
[0082] Reference Figure 10 and Figure 11 In some embodiments of the present invention, a fourth transmission protrusion 35 is provided in the threaded groove 31. When the transmission member 1 rotates clockwise, the sliding protrusion 13 is adapted to abut against the fourth transmission protrusion 35. For example, when the threaded groove 31 is provided on the output sleeve 3 and the threaded groove 31 does not extend to both ends of the output sleeve 3 in the first direction, and when the threaded groove 31 is provided on the transmission member 1 and the threaded groove 31 does not drive the transmission member 1 to both ends of the output sleeve 3 in the first direction, the third transmission protrusion 33 and the fourth transmission protrusion 35 are the sidewalls of the threaded groove 31 at both ends in its extension direction.
[0083] When the sliding cam 13 abuts against the fourth transmission cam 35, the second surface 112 abuts against the second transmission cam 21, the second pawl 412 disengages from the second groove 322 in the first direction, and the first pawl 411 abuts against the first ratchet 341 in the counterclockwise direction.
[0084] When the transmission component 1 is rotated clockwise, before the second transmission protrusion 21 abuts against the first surface 111, the transmission component 1 can first drive the output sleeve 3 to move in the first direction through the mutual cooperation of the threaded groove 31 and the sliding protrusion 13, and the limiting of the first pawl 411 and the first ratchet 341. The output sleeve 3 is driven to move in the direction from the second pawl 412 to the first pawl 411, gradually reducing the cooperation length between the second pawl 412 and the second groove 322 in the first direction, until the second transmission protrusion 21 abuts against the second surface 112, that is, after the transmission component 1 has rotated by the second rotation angle, the second pawl 41... 2. The first pawl 411 and the first ratchet 341 abut against each other in the counterclockwise direction. When the transmission component 1 rotates clockwise, the mutual cooperation between the first pawl 411 and the first ratchet 341 does not limit the output sleeve 3. The transmission component 1 can drive the output gear 2 to rotate clockwise through the abutment between the second surface 112 and the second transmission protrusion 21. At the same time, the output sleeve 3 is driven to rotate clockwise synchronously with the transmission component 1 through the stop between the sliding fitting protrusion 13 and the third transmission protrusion 33, thus ending the movement of the output sleeve 3 in the first direction.
[0085] When the output gear 2 rotates clockwise to the fourth preset angle, that is, when the transmission component 1 rotates the second rotation angle and continues to rotate the fourth preset angle, the transmission component 1 can be rotated counterclockwise. Since the first pawl 411 and the first ratchet 341 abut in the counterclockwise direction, the mutual cooperation between the first pawl 411 and the first ratchet 341 can limit the output sleeve 3 in the circumferential direction, restricting the rotation of the output sleeve 3. This allows the transmission component 1 to drive the output sleeve 3 to move in the reverse direction in the first direction through the limiting cooperation between the sliding lug 13 and the spiral groove. When the transmission component 1 rotates the second rotation angle in the reverse direction, the output sleeve 3 can be adjusted back to the initial state.
[0086] By setting two sets of opposite ratchet and pawl structures to limit the output sleeve 3, and setting a third transmission protrusion 33 in the spiral groove to stop the sliding protrusion 13 when the transmission component 1 rotates counterclockwise, the first pawl 411 and the second pawl 412 can take turns limiting the output sleeve 3 in the circumferential direction, effectively ensuring the reliability of the movement of the output sleeve 3 in the first direction, reducing the risk of the limiting component disengaging from the output sleeve 3, and improving the reliability of the output mechanism 100.
[0087] Simultaneously, after the transmission component 1 rotates counterclockwise by a first rotation angle to drive the output sleeve 3 to move in the first direction, the transmission component 1 can drive the output sleeve 3 to rotate, ending the movement of the output sleeve 3 in the first direction. This results in the output sleeve 3 occupying less space in the first direction, allowing the transmission component 1 to adjust the output sleeve 3 back to its initial state by rotating counterclockwise by a second rotation angle, regardless of how much the output gear 2 rotates clockwise. This increases the output angle range of the output gear 2 in the clockwise direction and improves the overall performance of the output mechanism 100. Applying the output mechanism 100 to a phase shifter allows for a larger phase adjustment range of the medium, enabling a more compact overall structure for the phase shifter.
[0088] Reference Figures 4-6 and Figure 13 In some embodiments of the present invention, the first pawl 411 is a flexible rebound component; for example, the first pawl 411 can be a rubber component or a silicone component. This allows the first pawl 411 to have a certain rebound energy. When the output sleeve 3 rotates counterclockwise and the first pawl 411 disengages from a first groove 321, the first pawl 411 can rebound back into the adjacent first groove 321 under its own rebound energy. It is not necessary to set an elastic component to press the first pawl 411 into the first groove 321, which reduces the number of components in the limiting component, simplifies the overall structure of the limiting component, reduces the production cost of the limiting component, and reduces the production cost of the output mechanism 100.
[0089] Reference Figures 4-6 and Figure 13 In some embodiments of the present invention, the second pawl 412 is a flexible rebound component; for example, the second pawl 412 can be a rubber component or a silicone component. This allows the second pawl 412 to have a certain rebound energy. When the output sleeve 3 rotates clockwise and the second pawl 412 disengages from a second groove 322, the second pawl 412 can rebound back into the adjacent second groove 322 under its own rebound energy. It is not necessary to provide an elastic component to press the second pawl 412 into the second groove 322, which reduces the number of components in the limiting component, simplifies the overall structure of the limiting component, reduces the production cost of the limiting component, and reduces the production cost of the output mechanism 100.
[0090] Reference Figures 4-5 and Figure 9According to some optional embodiments of the present invention, the transmission member 1 has a clearance hole 12, which opens toward the output gear 2. A first transmission protrusion 11 is disposed in the clearance hole 12, and a second transmission protrusion 21 passes through the clearance hole 12. This allows the transmission member 1 and the output gear 2 to occupy less space in the first direction, and allows the output mechanism 100 to be set smaller in the first direction.
[0091] Reference Figures 2-6 and Figure 16 According to some optional embodiments of the present invention, the second transmission path further includes an unlocking rod 6, which is provided with a groove 621, and the output sleeve 3 is provided with a shoulder 36. The shoulder 36 is arranged around the radial outer surface of the output sleeve 3 and is rotatably inserted in the groove 621.
[0092] When the transmission component 1 drives the output sleeve 3 to move in the first direction, the output sleeve 3 can drive the unlocking rod 6 to move through the stop of the shoulder 36 and the slide groove 621 in the first direction. When the transmission component 1 drives the output sleeve 3 to rotate, the shoulder 36 can rotate in the slide groove 621 to prevent the output sleeve 3 from driving the unlocking rod 6 to rotate, so that the unlocking rod 6 is fixed in the circumferential direction of the output sleeve 3, and the unlocking rod 6 can only move in the first direction.
[0093] For example, refer to Figures 1-8 The output mechanism 100 may also include a base 8, which includes an upper base 81 and a lower base 82. The upper base 81 and the lower base 82 together define a mounting groove 83 and a positioning groove 84. The mounting groove 83 has mounting holes on two side walls in the first direction. The transmission member 1 passes through the two mounting holes. The output sleeve 3 is sleeved on the transmission member 1 and is located in the mounting groove 83. There are two positioning grooves 84, and each positioning groove 84 is connected to the mounting groove 83. The two positioning grooves 84 are respectively arranged at intervals along the circumference of the mounting groove 83. For example, the two positioning grooves 84 can be respectively arranged on both sides of the mounting groove 83 in the second direction (refer to the e2 direction in the figure), or the two positioning grooves 84 can be respectively arranged on both sides of the mounting groove 83 in the third direction (refer to the e3 direction in the figure).
[0094] Reference Figure 2 and Figure 16 The unlocking lever 6 includes an unlocking part 61 and a limiting part 62. A sliding groove 621 is provided on the limiting part 62. The limiting part 62 is arc-shaped and surrounds the outer periphery of the output sleeve 3. The two ends of the limiting part 62 in the second direction are respectively inserted into the positioning groove 84. This allows the two mounting grooves 83 to limit the limiting part 62 in the second direction and the third direction, so that the limiting part 62 can only move in the first direction.
[0095] Reference Figures 1-6 and Figure 18In some optional embodiments of the present invention, the first transmission path further includes: an output rack 51, which is meshed with an output gear 2. The output gear 2 drives the output rack 51 to move in the second direction. In this way, the rotational motion of the output gear 2 can be converted into the motion of the output rack 51 in the second direction through the meshing between the output gear 2 and the output rack 51, thereby realizing the linear output of the output mechanism 100.
[0096] Reference Figures 1-6 , Figure 17 and Figure 18 The output rack 51 has a positioning tooth 511 on the side opposite to the output gear 2 in the third direction. There are multiple positioning teeth 511, and the multiple positioning teeth 511 are spaced apart along the first direction. The second transmission path also includes a locking ring 52, which is sleeved on the output rack 51. The radial inner surface of the locking ring 52 is provided with a limiting tooth 521 that matches the positioning tooth 511. For example, the base 8 is provided with a locking hole 85. The locking ring 52 is movably inserted into the locking hole 85 in the third direction. The locking hole 85 limits the locking ring 52 in the second direction.
[0097] This allows the locking ring 52 to lock the output rack 51 through the meshing of the limiting tooth 521 and the positioning tooth 511. Furthermore, positioning the positioning tooth 511 on the side of the output rack 51 facing away from the output gear 2 in the third direction makes the two surfaces of the output rack 51 relatively flat in the first direction, facilitating the installation of a sliding fit structure for positioning the output rack 51. For example, the base 8 can have a rack hole 86 through which the output rack 51 passes, with its two surfaces in the first direction abutting against the corresponding sidewalls of the rack hole 86.
[0098] Reference Figure 17 The locking ring 52 has a locking protrusion 522 on its radial outer surface, which protrudes from the radial outer surface of the locking ring 52; for example, the locking protrusion 522 can be triangular or semi-circular. The unlocking rod 6 and the locking ring 52 are arranged along a third direction. The unlocking rod 6 has a locking recess 611 facing the opening of the locking ring 52, and the locking protrusion 522 is adapted to pass through the locking recess 611; for example, referring to… Figure 16 The unlocking part 61 is provided with a locking recess 611. When the unlocking lever 6 moves in the first direction, this allows the unlocking lever 6 to push the locking protrusion 522 out of the locking recess 611 in the third direction and insert the locking protrusion 522 into the locking recess 611, thereby realizing the movement of the locking ring 52 in the third direction and realizing the power output of the locking ring 52. The overall structure is simple. For example, in order to facilitate the pushing of the locking protrusion 522 out of the locking recess 611, the two surfaces of the locking recess 611 in the first direction can be set as inclined surfaces, or the two surfaces of the locking protrusion 522 in the first direction can be set as arc surfaces.
[0099] When the locking protrusion 522 passes through the locking recess 611, the limiting tooth 521 engages with the positioning tooth 511, and the locking ring 52 locks the output rack 51, that is, the locking recess 611 of the unlocking rod 6 is in the locking area; when the locking protrusion 522 abuts against the area of the unlocking rod 6 excluding the locking recess 611, the limiting tooth 521 disengages from the positioning tooth 511, and the locking ring 52 unlocks the output rack 51, that is, the area of the unlocking rod 6 excluding the locking recess 611 is the unlocking area; wherein, the first direction intersects with the second direction, the first direction intersects with the third direction, and the second direction intersects with the third direction.
[0100] After the output mechanism 100 is assembled, the transmission component 1 can be rotated counterclockwise. Through the interaction between the threaded groove 31 and the sliding protrusion 13, and the interaction between the first pawl 411 and the first ratchet 341, the output sleeve 3 is limited in the circumferential direction. The output sleeve 3 is driven to move in the first direction, which in turn drives the unlocking rod 6 to move in the first direction. The locking protrusion 522 is stopped against the unlocking area of the unlocking rod 6. The locking protrusion 522 is pushed out of the locking recess 611 in the third direction, and the limiting tooth 521 is pushed out of the positioning tooth 511 in the third direction, unlocking the output rack 51. Then, the transmission component 1 is rotated counterclockwise. When the second transmission protrusion 21 stops against the first surface 111, the output gear 2 is driven to rotate counterclockwise synchronously with the transmission component 1 through the contact between the first surface 111 and the second transmission protrusion 21. This drives the output rack 51 to move in the first direction, and at the same time, through the interaction between the sliding protrusion 111 and the first surface 111, the output gear 2 is driven to rotate counterclockwise synchronously with the transmission component 1. The output sleeve 3, driven by the stop between the third transmission protrusion 33 and the third transmission protrusion 33, rotates counterclockwise synchronously with the transmission component 1, ending the movement of the unlocking rod 6 in the first direction. When the output rack 51 moves to its maximum limit position in the second direction, that is, when the output gear 2 stops against the base 8 in the first direction, the transmission component 1 can be rotated clockwise. Through the mutual cooperation between the threaded groove 31 and the sliding protrusion 13, and the mutual cooperation between the second pawl 412 and the second ratchet 342, the output sleeve 3 is limited in the circumferential direction, driving the output sleeve 3 to move in the opposite direction in the first direction. When the transmission component 1 rotates in the opposite direction by the first rotation angle, the output sleeve 3 can be adjusted back to the initial state, the unlocking rod 6 can be adjusted back to the initial state, the locking protrusion 522 can be inserted into the locking recess 611, and the positioning tooth 511 and the limiting tooth 521 can be meshed together to complete the locking of the output rack 51 and complete the zeroing setting of the output mechanism 100.
[0101] When position output is required via the output rack 51, the transmission component 1 can be rotated counterclockwise. Through the interaction of the threaded groove 31 and the sliding protrusion 13, and the interaction between the first pawl 411 and the first ratchet 341, the output sleeve 3 is limited in the circumferential direction. This first drives the output sleeve 3 to move in the first direction, driving the unlocking rod 6 to move in the first direction. The locking protrusion 522 is then stopped against the unlocking area of the unlocking rod 6. In the third direction, the locking protrusion 522 is pushed out of the locking recess 611, and the limiting tooth 521 is pushed out of the positioning tooth 511 in the third direction, unlocking the output rack 51. Then, the transmission component 1 continues to rotate counterclockwise. When the second transmission protrusion 21 stops against the first surface 111, the abutment between the first surface 111 and the second transmission protrusion 21 drives the output gear 2 to rotate counterclockwise synchronously with the transmission component 1, driving the output rack 51 to move in the first direction. Simultaneously, the stop between the sliding protrusion 13 and the third transmission protrusion 33 drives the output rack 51 to move in the first direction. The output sleeve 3 rotates counterclockwise in sync with the transmission component 1, ending the movement of the unlocking lever 6 in the first direction. When the output rack 51 moves to the first preset position in the second direction, that is, when the output gear 2 rotates counterclockwise to the third preset angle, that is, when the transmission component 1 continues to rotate to the third preset angle after rotating counterclockwise by the first rotation angle, the transmission component 1 can be rotated clockwise. Through the mutual cooperation between the threaded groove 31 and the sliding protrusion 13, and the mutual cooperation between the second pawl 412 and the second ratchet 342, the output sleeve 3 is limited in the circumferential direction, driving the output sleeve 3 to move in the opposite direction in the first direction. When the transmission component 1 rotates in the opposite direction by the first rotation angle, the output sleeve 3 can be adjusted back to the initial state, the unlocking lever 6 can be adjusted back to the initial state, the locking protrusion 522 can be inserted into the locking recess 611, and the positioning tooth 511 and the limiting tooth 521 can be meshed together to complete the locking of the output rack 51. The output rack 51 is adjusted to the preset position and locked.
[0102] When position output is required via the output rack 51, the transmission component 1 can be rotated clockwise. Through the interaction of the threaded groove 31 and the sliding protrusion 13, and the interaction between the second pawl 412 and the second ratchet 342, the output sleeve 3 is limited in the circumferential direction. This first drives the output sleeve 3 to move in the first direction, driving the unlocking rod 6 to move in the first direction. The locking protrusion 522 is then stopped against the unlocking area of the unlocking rod 6. In the third direction, the locking protrusion 522 is pushed out of the locking recess 611, and the limiting tooth 521 is pushed out of the positioning tooth 511 in the third direction, unlocking the output rack 51. Then, the transmission component 1 continues to rotate clockwise. When the second transmission protrusion 21 abuts against the second surface 112, the abutment between the second surface 112 and the second transmission protrusion 21 drives the output gear 2 to rotate clockwise synchronously with the transmission component 1, driving the output rack 51 to move in the first direction. Simultaneously, through the interaction of the sliding protrusion 13 and the fourth transmission... The stop drive output sleeve 3 between the convex 35 rotates clockwise synchronously with the transmission component 1, ending the movement of the unlocking rod 6 in the first direction; when the output rack 51 moves to the second preset position in the second direction, that is, when the output gear 2 rotates counterclockwise to the fourth preset angle, that is, when the transmission component 1 continues to rotate the fourth preset angle after rotating the second rotation angle in the opposite direction, the transmission component 1 can be rotated counterclockwise. Through the mutual cooperation between the threaded groove 31 and the sliding convex 13, and the mutual cooperation between the second pawl 412 and the second ratchet 342, the output sleeve 3 is limited in the circumferential direction, driving the output sleeve 3 to move in the opposite direction in the first direction. When the transmission component 1 rotates the first rotation angle in the opposite direction, the output sleeve 3 can be adjusted back to the initial state, the unlocking rod 6 can be adjusted back to the initial state, the locking convex 522 can be inserted into the locking recess 611, and the positioning tooth 511 and the limiting tooth 521 can be meshed together to complete the locking of the output rack 51.
[0103] In some optional embodiments of the present invention, the output mechanism 100 further includes: a base 8 and a pressing member 9, see reference. Figure 7 The base 8 is provided with a rack hole 86, and the output rack 51 passes through the rack hole 86. The two side surfaces of the output rack 51 in the first direction respectively abut against the side wall of the rack hole 86; see reference. Figure 2 and Figure 18 The positioning tooth 511 is provided with a clearance notch 512, which penetrates the positioning tooth 511 along the second direction and extends upward along the third direction to the surface where the output gear 2 is located. (Refer to...) Figures 2-4The pressing member 9 is connected and fixed to the base 8. The pressing member 9 passes through the clearance notch 512 and abuts against the surface where the output gear 2 is located. For example, the base 8 has a damping groove 87, and the pressing member 9 passes through the damping groove 87. In this way, the two side walls of the rack hole 86 in the first direction can be used to limit the output rack 51, so that the output gear 2 and the pressing member 9 cooperate to limit the output rack 51 in the third direction. This allows the output rack 51 to move reliably in the first direction, reduces the risk of the output rack 51 deviating when moving in the first direction, and improves the reliability of the output mechanism 100.
[0104] For example, the pressing element 9 can be a damping plate. When the output rack 51 moves, the damping plate can quantify the assembly gap on the first transmission path and improve the displacement accuracy of the output rack 51.
[0105] Reference Figures 1-5 In some optional embodiments of the present invention, the second transmission path further includes a first elastic element, which is disposed on the side of the locking ring 52 facing away from the unlocking lever 6 in the third-order direction, to drive the locking ring 52 to move toward the unlocking lever 6 in the third-order direction. For example, the first elastic element can be a spring, a sheet, a rubber component, or a silicone component. For example, the first elastic element can be disposed in the locking hole 85. This allows the first elastic element to apply force to the locking ring 52, so that the locking protrusion 522 of the locking ring 52 can reliably abut in the third-order direction, so that the locking protrusion 522 can reliably insert into the locking recess 611, so that the positioning tooth 511 and the limiting tooth 521 can reliably mesh together, so that the locking ring 52 can reliably limit the output gear 2, so that the output gear 2 can be reliably positioned at a preset position, thereby improving the reliability of the output mechanism 100.
[0106] According to a second aspect embodiment of the present invention, a base station antenna includes: an output mechanism 100 and a phase shifter according to the first aspect embodiment of the present invention, wherein a medium in the phase shifter is connected to an output gear 2 of the output mechanism 100. For example, the medium can be connected to the output gear 2 via an output rack 51 so that the medium can move under the drive of a first transmission path.
[0107] According to the base station antenna of the present invention, the overall structure is simple through the phase shifter described above. The power transmission during medium position adjustment can be realized by using an output mechanism 100, and the power transmission for unlocking and locking the medium position can be realized. Moreover, the medium position adjustment movement can be independent of the medium position locking and unlocking movement, ensuring the reliability of the phase shifter operation. This allows the output mechanism 100 to be equipped with only one driving element, reducing the number of driving elements in the phase shifter, reducing the production cost of the phase shifter, and reducing the production cost of the base station antenna.
