Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of communication equipment, and in particular to an output mechanism and a base station antenna. Background Art
[0002] The antenna transmission mechanism is often used to control components such as phase shifters to achieve phase changes, so as to achieve rapid optimization of the antenna coverage network. At present, the transmission mechanism output mechanism often uses screw clamps or gear racks to adjust the displacement. Since the gear rack output mechanism has a compact structure, simple installation, lower cost, and smaller space occupation, more and more antenna manufacturers are adopting this solution.
[0003] However, the gear rack output mechanism must leave appropriate tooth side clearance to avoid transmission jamming, which makes its displacement accuracy low. Therefore, a locking mechanism is added to the gear rack output mechanism to lock the rack after displacement to improve its position accuracy, which often requires the addition of another power input device, which makes the antenna structure more complicated and the maintenance cost high. Summary of the invention
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present invention is to propose an output mechanism with a simple overall structure, which can realize the intermittent movement of the output gear and the output of the output sleeve in the first direction, and at the same time, the output sleeve can be restored to the initial state by utilizing the gap between the transmission member and the output gear when the transmission relationship is disengaged, so as to realize the output of two different force transmission paths, and the rotational movement of the output gear is independent of the movement of the output sleeve in the first direction, so that the output mechanism can be provided with only one driving member to realize the output of two different force transmission paths, thereby reducing the production cost of the output mechanism and the production cost of the phase shifter.

[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0051] Please refer to the following drawings Figure 1-Figure 18 An output mechanism according to an embodiment of the present invention is described.
[0052] The output mechanism 100 according to the first embodiment of the present invention comprises: a first transmission path and a second transmission path, wherein the first transmission path comprises a transmission member 1 and an output gear 2 arranged along a first direction (refer to the e1 direction in the drawings), Figure 5 , Figure 6 , Fig. 9 and Fig.15 A first transmission protrusion 11 and a second transmission protrusion 21 are respectively provided on the transmission member 1 and the output gear 2. The two end faces of the first transmission protrusion 11 in the circumferential direction of the output gear 2 are respectively a first face 111 and a second face 112. When the transmission member 1 rotates counterclockwise, the first face 111 is suitable for stopping the second transmission protrusion 21. When the transmission member 1 rotates clockwise, the second face 112 is suitable for stopping the second transmission protrusion 21.
[0053] It needs to be explained that the rotation direction of the transmission member 1 is related to the observation direction. The description of the rotation direction of the transmission member 1 in the present application, "the transmission member 1 rotates counterclockwise" and "the transmission member 1 rotates clockwise", is only to describe the two opposite rotation directions of the transmission member 1 and is not specifically limited.
[0054] When the second transmission protrusion 21 rotates between the position where it stops at the first surface 111 and the position where it stops at the second surface 112, the transmission member 1 is out of 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 when it rotates from the initial position to the position where it stops at 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 when it rotates from the initial position to the position where it stops at the second surface 112 is the second rotation angle.
[0055] When the first surface 111 and the second transmission protrusion 21 stop abutting each other, the transmission member 1 rotates clockwise, and before the second transmission protrusion 21 stops abutting each other against the second surface 112, the transmission member 1 does not drive the output gear 2 to rotate, and the transmission member 1 idles (wherein the idle rotation angle of the transmission member 1 is the sum of the first rotation angle and the second rotation angle), until the second transmission protrusion 21 stops abutting each other against the second surface 112, and 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 stops against the second transmission protrusion 21, the transmission member 1 rotates counterclockwise. Before the second transmission protrusion 21 stops against the first surface 111, the transmission member 1 does not drive the output gear 2 to rotate, and 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 stops against the first surface 111, the transmission member 1 drives the output gear 2 to rotate counterclockwise through the contact between the first transmission protrusion 11 and the second transmission protrusion 21.
[0057] Reference Figure 2 , Figure 4 , Figure 9-12 The second transmission path includes an output sleeve 3 and a limit assembly, the output sleeve 3 is sleeved on the transmission member 1, one of the output sleeve 3 and the transmission member 1 is provided with a thread groove 31, and the other of the output sleeve 3 and the transmission member 1 is provided with a sliding protrusion 13 penetrating in the thread groove 31. For example, when the output sleeve 3 is provided with the thread groove 31, the transmission member 1 is provided with the sliding protrusion 13; when the output sleeve 3 is provided with the sliding protrusion 13, the transmission member 1 is provided with the thread groove 31.
[0058] For example, when the output sleeve 3 is provided with a thread groove 31, the thread groove 31 may penetrate the output sleeve 3 in the radial direction, or the thread groove 31 may not penetrate the output sleeve 3 in the radial direction; when the thread groove 31 does not penetrate the output sleeve 3 in the radial direction, the output sleeve 3 may be manufactured by dividing it into two independent parts by a plane passing through its central axis, so as to reduce the difficulty of production and processing of the output sleeve 3 and reduce the production cost of the output sleeve 3. Specifically, referring to Figure 10-12 The output sleeve 3 can be assembled by the first tube wall 37 and the second tube wall 38. The surface where the first tube wall 37 and the second tube wall 38 abut each other is provided with an anti-fool column 371, and the second tube wall 38 is provided with an anti-fool hole 381. The anti-fool column 371 is inserted into the anti-fool hole 381, and the distances from the anti-fool column 371 to the two ends of the output sleeve 3 in the first direction are different. In this way, the anti-fool column 371 and the anti-fool hole 381 can play an anti-fool role in the assembly of the output sleeve 3, so that the part of the thread groove 31 located on the first tube wall 37 can be correctly assembled with the part of the thread groove 31 located on the second tube wall 38, avoiding the risk of discontinuity of the thread groove 31 caused by installing the first tube wall 37 relative to the second tube wall 38, and facilitating the assembly of the output sleeve 3.
[0059] When the transmission member 1 rotates, the transmission member 1 can drive the output sleeve 3 to move in the first direction through the mutual cooperation between the thread groove 31 and the sliding protrusion 13; it should be understood that no matter whether the thread groove 31 is left-handed or right-handed, the transmission member 1 can drive the output sleeve 3 to move in the first direction when it rotates, but the movement direction of the output sleeve 3 in the first direction is different.
[0060] Reference Figure 4-Figure 6 , the limiting assembly is arranged on the radial outer side of the output sleeve 3, one of the limiting assembly and the output sleeve 3 is provided with a limiting protrusion 41, and the other of the limiting assembly and the output sleeve 3 is provided with a limiting groove 32 extending along the first direction, and the limiting protrusion 41 is slidably arranged in the limiting groove 32; wherein the first direction is parallel to the rotation center line of the transmission member 1. For example, when the limiting assembly is provided with the limiting protrusion 41, the output sleeve 3 is provided with the limiting groove 32 extending along the first direction; when the limiting assembly is provided with the limiting groove 32, the output sleeve 3 is provided with the limiting protrusion 41 extending along the first direction.
[0061] The limiting protrusion 41 cooperates with the limiting groove 32 to limit the output sleeve 3 in the circumferential direction of the transmission member 1 to prevent the output sleeve 3 from rotating with the transmission member 1. When the transmission member 1 is rotated, the transmission member 1 can drive the output sleeve 3 to move in the first direction through the mutual cooperation between the thread 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 drives 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 drives the output sleeve 3 to move toward the output gear 2 in the first direction when rotating counterclockwise.
[0062] When the first surface 111 and the second transmission protrusion 21 stop abutting, the transmission member 1 rotates clockwise, and before the second transmission protrusion 21 stops abutting the second surface 112, since the transmission member 1 has a certain idling angle when rotating clockwise (for example, the idling angle when the transmission member 1 rotates clockwise is the second rotation angle), the transmission member 1 can first drive the output sleeve 3 to move in the first direction through the mutual cooperation between the thread groove 31 and the sliding protrusion 13, until the second transmission protrusion 21 and the second surface 112 stop abutting, 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, and at the same time keeps driving the output sleeve 3 to move in the first direction; when the transmission member 1 rotates clockwise to the first preset angle, the transmission member 1 can be rotated counterclockwise, and by rotating in the opposite direction by the first preset angle, the output sleeve 3 is driven to move in the opposite direction along 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 being driven to rotate when the transmission member 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 and the second transmission protrusion 21 stop, the transmission member 1 is rotated counterclockwise, and before the second transmission protrusion 21 stops the first surface 111, since the transmission member 1 has a certain idling angle when rotating counterclockwise (for example, the idling angle when the transmission member 1 rotates clockwise is the first rotation angle), the transmission member 1 can first drive the output sleeve 3 to move in the first direction through the mutual cooperation between the thread groove 31 and the sliding protrusion 13, until the second transmission protrusion 21 and the first surface 111 stop, the transmission member 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 drives the output sleeve 3 to continue to move in the first direction; when the transmission member 1 rotates counterclockwise to the second preset angle, the transmission member 1 can be rotated clockwise, and the output sleeve 3 is driven to move in the opposite direction along the first direction by rotating in the opposite direction by the second preset angle, so as to adjust the output sleeve 3 back to the initial state. It should be understood that in order to prevent the output sleeve 3 from being driven to rotate when the transmission member 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] In this way, intermittent movement of the output gear 2 can be achieved, and the output sleeve 3 can be restored to its initial state by utilizing the gap between the transmission member 1 and the output gear 2 when the transmission relationship is broken. The overall structure is simple, and two different force transmission path outputs can be achieved. The rotational movement of the output gear 2 can be made independent of the movement of the output sleeve 3 in the first direction, so that the output mechanism 100 can be provided with only one driving member to achieve two different force transmission path outputs, thereby reducing the production cost of the output mechanism 100.
[0065] By providing mutually matching first transmission protrusions 11 and second transmission protrusions 21 between the transmission member 1 and the output gear 2, and providing mutually matching thread grooves 31 and sliding protrusions 13 between the output sleeve 3 and the transmission member 1, when the transmission member 1 is rotated counterclockwise, the transmission member 1 can drive the output sleeve 3 to move in the first direction to realize the output of the output sleeve 3 in the first direction. After the transmission member 1 rotates a certain angle, the first surface 111 can stop against the second transmission protrusion 21, so that the transmission member 1 drives the output gear 2 to rotate counterclockwise to realize the rotational output of the output gear 2. After driving the output gear 2 to rotate counterclockwise by a preset angle, the transmission member 1 can be rotated clockwise to drive the output sleeve 3 to move in the first direction. The output sleeve 3 is adjusted to the initial state. When 21 rotates between the position of the first stop surface 111 and the position of the second stop surface 112, the transmission member 1 and the output gear 2 are disengaged from the transmission relationship. When the transmission member 1 is rotated clockwise to adjust the output sleeve 3 to the initial state, the transmission member 1 does not drive the output gear 2 to reverse, that is, the intermittent movement of the output gear 2 can be achieved. At the same time, the gap between the transmission member 1 and the output gear 2 that is disengaged from the transmission relationship can be used to restore the output sleeve 3 to the initial state. The overall structure is simple, and two different types of force transmission path outputs can be achieved. The rotational movement of the output gear 2 can be independent of the movement of the output sleeve 3 in the first direction, so that the output mechanism 100 can be provided with only one driving member to achieve two different types of force transmission path outputs, thereby 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 protrusion 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 protrusion 21 can be set to be different, so that the output gear 2 has different output angles in the forward and reverse directions, satisfying the diversified 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, so that the output angle of the output gear 2 in this direction is larger.
[0067] For example, the output mechanism 100 can be applied to a device that needs to be adjusted in position and positioned after the position adjustment is completed, such as a phase shifter, an angle adjuster for a camera, and an angle adjuster for a vehicle rearview mirror; specifically, refer to Figure 1-Figure 4 When the output mechanism 100 is applied to a 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, and 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 the phase shifter, when the phase needs to be adjusted, the transmission member 1 can be rotated clockwise (or counterclockwise) to drive the output sleeve 3 to move in the first direction, and the unlocking rod 6 is driven to move in the first direction through the output sleeve 3, and the unlocking area of the unlocking rod 6 is driven to correspond to the output rack 51 to unlock the output gear 2, until the second transmission protrusion 21 stops against the second surface 112, and the transmission member 1 drives the output rack 51 to move by rotating the output gear 2 clockwise (or the transmission member 1 drives the output rack 51 to move counterclockwise by rotating the output gear 2). When the medium is adjusted to a preset position in the first direction, that is, the transmission member 1 rotates clockwise to a first preset angle (that is, the transmission member 1 rotates clockwise to a second preset angle), the transmission member 1 can be rotated in the reverse direction, and the output sleeve 3 is driven to move in the reverse direction along the first direction by rotating in the reverse direction by the first preset angle, and the output sleeve 3 is adjusted back to its initial state, and the locking area of the unlocking rod 6 is driven to correspond to the output rack 51, and the output rack 51 is locked, thereby completing the phase adjustment.
[0069] For example, when the first rotation angle and the second rotation angle are set equal, the unlocking rod 6 has two unlocking areas and one locking area, and the two unlocking areas are respectively 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 rod 6 has one unlocking area and one locking area.
[0070] In this way, the output gear 2 can be used to drive the medium to adjust the position to adjust the phase, meeting the medium position driving requirements of the phase shifter, and the output sleeve 3 can be used to lock the medium and unlock the limit on the medium by moving in the first direction, reducing the risk of the medium moving out of the preset position and causing the phase to change, meeting the requirement of locking the medium position at the preset position, so that the output mechanism 100 can be arranged in the phase shifter to adjust the position of the medium, and the medium position adjustment movement can be independent of the locking and unlocking movement of the medium position, thereby ensuring the reliability of the phase shifter operation, reducing the number of drive components set in the phase shifter, and reducing the production cost of the phase shifter.
[0071] For example, refer to Figure 1-Figure 3 and Fig.14The output mechanism 100 also includes an adapter 7, which includes a meshing portion 71 and a plug-in portion 72. The meshing portion 71 is meshed with the gear of the transmission member 1, and the plug-in portion 72 is provided with a spline for connecting the output shaft of the driving member to ensure that the driving member can transmit power to the adapter 7, so that the adapter 7 can drive the transmission member 1 to rotate. Moreover, by setting the adapter between the driving member and the transmission member 1, the output direction of the power can be changed by setting the meshing portion 71 and the transmission member 1 as bevel gears, which is convenient for the spatial arrangement of the driving member. Specifically, the driving member can be a driving motor, or a rotating oil cylinder.
[0072] According to the output mechanism 100 of the present invention, by providing mutually matching first transmission protrusions 11 and second transmission protrusions 21 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 be disengaged from the transmission when the second transmission protrusion 21 rotates between the position of the stopper first surface 111 and the position of the stopper second surface 112, so that the intermittent movement of the output gear 2 can be achieved, and mutually matching thread grooves 31 and sliding protrusions 13 are provided between the output sleeve 3 and the transmission member 1, so that the output of the output sleeve 3 in the first direction can be achieved, and at the same time, the gap between the transmission member 1 and the output gear 2 that is disengaged from the transmission relationship can be used to restore the output sleeve 3 to the initial state. The overall structure is simple, and two different modes of force transmission path output can be achieved, and the rotational movement 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 be provided with only one driving member to realize the output of two different force transmission paths, thereby reducing the production cost of the output mechanism 100; moreover, in this way, the output gear 2 can be used to drive the medium to adjust the position to adjust the phase, thereby meeting the medium position driving requirement of the phase shifter, and the output sleeve 3 can be used to lock and unlock the medium, thereby reducing the risk of the medium being displaced from the preset position and causing the phase to change, thereby meeting the requirement of locking the medium position at the preset position, so that the output mechanism 100 can be provided in the phase shifter to adjust the position of the medium, and the medium position adjustment movement can be independent of the locking and unlocking movement of the medium position, thereby ensuring the reliability of the phase shifter operation, reducing the number of driving members provided in the phase shifter, and reducing the production cost of the phase shifter.
[0073] Reference Figure 10-12 According to some embodiments of the present invention, a third transmission protrusion 33 is provided in the thread groove 31, and when the transmission member 1 rotates counterclockwise, the sliding protrusion 13 is suitable for stopping the third transmission protrusion 33; for example, when the thread groove 31 is provided on the output sleeve 3, and the thread groove 31 does not extend to both ends of the output sleeve 3 in the first direction, and when the thread groove 31 is provided on the transmission member 1, and the thread groove 31 does not extend from the transmission member 1 to both ends of the output sleeve 3 in the first direction, the third transmission protrusion 33 is the side wall of the thread groove 31 in its extension direction.
[0074] Reference Figure 4-Figure 6 , Fig.10 and Fig.13 The limiting groove 32 includes a first groove body 321 and a second groove body 322. A plurality of first ratchet teeth 341 and a plurality of second ratchet teeth 342 are provided on the radial outer peripheral side of the output sleeve 3. 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 a first groove body 321; that is, in the clockwise direction, the radial size of the first ratchet tooth 341 of the output sleeve 3 gradually decreases, that is, in the clockwise direction, the radial size of the first groove body 321 of the output sleeve 3 gradually increases.
[0075] Reference Figure 4-Figure 6 , Fig.10 and Fig.13 The second ratchet teeth 342 and the first ratchet teeth 341 are arranged at intervals along the first direction, and multiple second ratchet teeth 342 are arranged at intervals along the circumference of the output sleeve 3, and each second ratchet tooth 342 is arranged in a counterclockwise direction, and two adjacent second ratchet teeth 342 define a second groove body 322; that is, in the counterclockwise direction, the radial size of the second ratchet teeth 342 in the output sleeve 3 gradually decreases; that is, in the counterclockwise direction, the radial size of the second groove body 322 in the output sleeve 3 gradually increases.
[0076] Reference Figure 4-Figure 6 , Fig.10 and Fig.13 The limiting protrusion 41 includes a first pawl 411 and a second pawl 412. The first ratchet tooth 341 and the first pawl 411 are suitable for abutting in the counterclockwise direction, and the second ratchet tooth 342 and the second pawl 412 are suitable for abutting in the clockwise direction. For example, the second pawl 412 can be arranged on the side of the first pawl 411 away from the output gear 2; when the sliding protrusion 13 stops against the third transmission protrusion 33, the first surface 111 stops against the second transmission protrusion 21, the first pawl 411 disengages from the first groove body 321 in the first direction, and the second ratchet tooth 342 and the second pawl 412 abut in the clockwise direction.
[0077] When the transmission member 1 rotates counterclockwise, before the second transmission protrusion 21 stops against the first surface 111, the transmission member 1 can first drive the output sleeve 3 to move in the first direction through the mutual cooperation between the thread groove 31 and the sliding protrusion 13, and the limitation of the first pawl 411 and the first ratchet tooth 341, and drive the output sleeve 3 to move in the direction from the first pawl 411 to the second pawl 412, gradually reducing the matching length of the first pawl 411 and the first groove body 321 in the first direction, until the second transmission protrusion 21 stops against the first surface 111, that is, after the transmission member 1 rotates by the first rotation angle, the first pawl 41 1 is out of the limiting relationship with the first groove body 321 in the circumferential direction of the transmission member 1; since the second pawl 412 and the second ratchet tooth 342 are in abutment with each other in the clockwise direction, when the transmission member 1 rotates counterclockwise, the mutual cooperation between the second pawl 412 and the second ratchet tooth 342 does not limit the output sleeve 3, and the transmission member 1 can drive the output gear 2 to rotate counterclockwise through the abutment between the first surface 111 and the second transmission protrusion 21, and at the same time, the output sleeve 3 is driven to rotate counterclockwise synchronously with the transmission member 1 through the stop between the sliding protrusion 13 and the third transmission protrusion 33, thereby 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 member 1 continues to rotate the third preset angle after rotating against the trend by the first rotation angle, the transmission member 1 can be rotated clockwise. Since the second pawl 412 abuts the second ratchet tooth 342 in the clockwise direction, at this time, the mutual cooperation between the second pawl 412 and the second ratchet tooth 342 can limit the output sleeve 3 in the circumferential direction, restricting the rotation of the output sleeve 3, so that the transmission member 1 drives the output sleeve 3 to move in the opposite direction along the first direction through the limiting cooperation between the sliding protrusion 13 and the spiral groove. When the transmission member 1 rotates in the opposite direction by the first rotation angle, 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 that is suitable for stopping the sliding protrusion 13 when the transmission member 1 rotates counterclockwise, the first pawl 411 and the second pawl 412 can limit the output sleeve 3 in the circumferential direction in turn, effectively ensuring the reliability of the output sleeve 3 moving in the first direction, reducing the risk of separation between the limit assembly and the output sleeve 3, and improving the reliability of the output mechanism 100.
[0080] At the same time, after the transmission member 1 rotates counterclockwise by the first rotation angle to drive the output sleeve 3 to move in the first direction, the transmission member 1 can drive the output sleeve 3 to rotate, ending the movement of the output sleeve 3 in the first direction, so that the space occupied by the output sleeve 3 in the first direction is small, so that no matter how much the transmission member 1 drives the output gear 2 to rotate counterclockwise, the output sleeve 3 can be adjusted back to the initial state by rotating the transmission member 1 clockwise by the first rotation angle, thereby increasing the output angle range of the output gear 2 in the counterclockwise direction and improving the overall performance of the output mechanism 100. When the output mechanism 100 is applied to the phase shifter, the medium can have a larger phase adjustment range, so that the overall structure of the phase shifter can be set more compactly.
[0081] For example, the limiting assembly may also include a second elastic member and a third elastic member, the second elastic member is used to press the first pawl 411 against the first groove body 321 in the radial direction of the output sleeve 3, so that the first pawl 411 and the first ratchet tooth 341 can cooperate reliably, and the third elastic member is used to press the second pawl 412 against the second groove body 322 in the radial direction of the output sleeve 3, so that the second pawl 412 and the second ratchet tooth 342 can cooperate reliably, thereby improving the reliability of the output mechanism 100.
[0082] Reference Fig.10 and Fig.11 In some embodiments of the present invention, according to some embodiments of the present invention, a fourth transmission protrusion 35 is provided in the thread groove 31, and when the transmission member 1 rotates clockwise, the sliding protrusion 13 is suitable for stopping the fourth transmission protrusion 35; for example, when the thread groove 31 is provided on the output sleeve 3, and the thread groove 31 does not extend to both ends of the output sleeve 3 in the first direction, and when the thread groove 31 is provided on the transmission member 1, and the thread groove 31 does not extend from 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 side walls of the thread groove 31 at both ends in its extension direction.
[0083] When the sliding protrusion 13 abuts against the fourth transmission protrusion 35 , the second surface 112 abuts against the second transmission protrusion 21 , the second pawl 412 disengages from the second slot 322 in the first direction, and the first pawl 411 abuts against the first ratchet tooth 341 in the counterclockwise direction.
[0084] When the transmission member 1 rotates clockwise, before the second transmission protrusion 21 stops against the first surface 111, the transmission member 1 can first drive the output sleeve 3 to move in the first direction through the mutual cooperation between the thread groove 31 and the sliding protrusion 13, and the limitation of the first pawl 411 and the first ratchet tooth 341, and drive the output sleeve 3 to move in the direction from the second pawl 412 to the first pawl 411, gradually reducing the matching length of the second pawl 412 and the second groove body 322 in the first direction, until the second transmission protrusion 21 stops against the second surface 112, that is, after the transmission member 1 rotates by the second rotation angle, the second pawl 41 2 and the second groove body 322 are out of the limiting relationship in the circumferential direction of the transmission member 1; since the first pawl 411 and the first ratchet tooth 341 are in abutment with each other in the counterclockwise direction, when the transmission member 1 rotates clockwise, the mutual cooperation between the first pawl 411 and the first ratchet tooth 341 does not limit the output sleeve 3, and the transmission member 1 can drive the output gear 2 to rotate clockwise through the abutment between the second surface 112 and the second transmission protrusion 21, and at the same time, the output sleeve 3 is driven to rotate clockwise synchronously with the transmission member 1 through the stop between the sliding protrusion 13 and the third transmission protrusion 33, thereby 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 member 1 continues to rotate to the fourth preset angle after rotating by the second rotation angle, the transmission member 1 can be rotated counterclockwise. Since the first pawl 411 abuts against the first ratchet tooth 341 in the counterclockwise direction, at this time, the mutual cooperation between the first pawl 411 and the first ratchet tooth 341 can limit the output sleeve 3 in the circumferential direction, restricting the rotation of the output sleeve 3, so that the transmission member 1 drives the output sleeve 3 to move in the opposite direction along the first direction through the limiting cooperation between the sliding protrusion 13 and the spiral groove. When the transmission member 1 rotates in the opposite direction by the second rotation angle, 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 that is suitable for stopping the sliding protrusion 13 when the transmission member 1 rotates counterclockwise, the first pawl 411 and the second pawl 412 can limit the output sleeve 3 in the circumferential direction in turn, effectively ensuring the reliability of the output sleeve 3 moving in the first direction, reducing the risk of separation between the limit assembly and the output sleeve 3, and improving the reliability of the output mechanism 100.
[0087] At the same time, after the transmission member 1 rotates counterclockwise by the first rotation angle to drive the output sleeve 3 to move in the first direction, the transmission member 1 can drive the output sleeve 3 to rotate, ending the movement of the output sleeve 3 in the first direction, so that the space occupied by the output sleeve 3 in the first direction is small, so that no matter how much the transmission member 1 drives the output gear 2 to rotate clockwise, the output sleeve 3 can be adjusted back to the initial state by rotating the transmission member 1 counterclockwise by the second rotation angle, thereby increasing the output angle range of the output gear 2 in the clockwise direction and improving the overall performance of the output mechanism 100. When the output mechanism 100 is applied to the phase shifter, the medium can have a larger phase adjustment range, so that the overall structure of the phase shifter can be set more compactly.

In this way, the first pawl 411 can have a certain resilience performance. When the output sleeve 3 rotates counterclockwise and the first pawl 411 escapes from one of the first slots 321, the first pawl 411 can rebound to the first slot 321 adjacent to it under its own resilience performance, and it is not necessary to set an elastic member to press the first pawl 411 into the first slot 321, so that the components of the limit assembly are fewer, the overall structure of the limit assembly is simple, the production cost of the limit assembly is reduced, and the production cost of the output mechanism 100 is reduced.

In this way, the space occupied by the transmission member 1 and the output gear 2 in the first direction can be smaller, so that the size of the output mechanism 100 in the first direction can be set smaller.

The boss 36 is arranged on the radial outer surface of the output sleeve 3, and the boss 36 can be rotatably inserted into the slide groove 621.
[0092] When the transmission member 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 boss 36 and the slide groove 621 in the first direction. When the transmission member 1 drives the output sleeve 3 to rotate, the boss 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 position of the unlocking rod 6 in the circumferential direction of the output sleeve 3 remains fixed, so that the unlocking rod 6 can only move in the first direction.

[0094] Reference Figure 2 and Fig.16 The unlocking lever 6 includes an unlocking portion 61 and a limiting portion 62. The sliding groove 621 is arranged on the limiting portion 62. The limiting portion 62 is arc-shaped and surrounded by the outer peripheral side of the output sleeve 3. The two ends of the limiting portion 62 in the second direction are respectively penetrated in the positioning grooves 84, so that the two mounting grooves 83 can limit the limiting portion 62 in the second direction and the third direction, so that the limiting portion 62 only moves in the first direction.
[0095] Reference Figure 1-Figure 6 and Fig.18In some optional embodiments of the present invention, the first transmission path also includes: an output rack 51, the output rack 51 is meshed with the output gear 2, and 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 mutual meshing between the output gear 2 and the output rack 51, thereby realizing the linear output of the output mechanism 100.
[0096] Reference Figure 1-Figure 6 , Fig.17 and Fig.18 The output rack 51 is provided with a positioning tooth 511 on the side away from the output gear 2 in the third direction, and there are multiple positioning teeth 511, and the multiple positioning teeth 511 are arranged at intervals along the first direction; the second transmission path also includes: a locking ring 52, the locking ring 52 is sleeved on the output rack 51, and a limiting tooth 521 matched with the positioning tooth 511 is provided on the radial inner surface of the locking ring 52. For example, a locking hole 85 is provided on the base 8, and the locking ring 52 is movably penetrated in the locking hole 85 along the third direction, and the locking hole 85 limits the locking ring 52 in the second direction.
[0097] In this way, the locking ring 52 can lock the output rack 51 through the mutual meshing between the limiting teeth 521 and the positioning teeth 511. Moreover, by arranging the positioning teeth 511 on the side of the output rack 51 in the third direction away from the output gear 2, the two surfaces of the output rack 51 in the first direction can be relatively flat, which is convenient for arranging the sliding structure to position the output rack 51. For example, the base 8 can be provided with a rack hole 86, the output rack 51 is penetrated by the rack hole 86, and the two surfaces of the output rack 51 in the first direction are respectively stopped against the side walls corresponding to the rack hole 86.
[0098] Reference Fig.17 The locking ring 52 is provided with a locking protrusion 522 on its radial outer surface, and the locking protrusion 522 protrudes from the radial outer surface of the locking ring 52; for example, the locking protrusion 522 may be triangular or semicircular. The unlocking lever 6 and the locking ring 52 are arranged along the third direction, and the unlocking lever 6 is provided with a locking recess 611 opening toward the locking ring 52, and the locking protrusion 522 is suitable for being inserted into the locking recess 611; for example, referring to Fig.16 The unlocking portion 61 is provided with a locking recess 611. When the unlocking lever 6 moves in the first direction, the unlocking lever 6 can 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, so as to realize the movement of the locking ring 52 in the third direction and realize the power output of the locking ring 52, and the overall structure is simple. For example, in order to facilitate the ejection of the locking protrusion 522 from the locking recess 611, the two surfaces of the locking recess 611 in the first direction can be set as inclined surfaces, and the two surfaces of the locking protrusion 522 in the first direction can also be set as arcuate surfaces.
[0099] When the locking protrusion 522 is inserted into the locking recess 611, the limiting tooth 521 is meshed 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 stops at the area on the unlocking rod 6 except the locking recess 611, the limiting tooth 521 is disengaged from the positioning tooth 511, and the locking ring 52 unlocks the output rack 51, that is, the area on the unlocking rod 6 except 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 member 1 can be rotated counterclockwise to limit the output sleeve 3 in the circumferential direction through the mutual cooperation between the thread groove 31 and the sliding protrusion 13, and the mutual cooperation between the first pawl 411 and the first ratchet tooth 341, so as to first drive the output sleeve 3 to move in the first direction, drive the unlocking rod 6 to move in the first direction, stop the locking protrusion 522 in the unlocking area of the unlocking rod 6, and push the locking protrusion 522 out of the locking recess 611 in the third direction, and push the limiting tooth 521 out of the positioning tooth 511 in the third direction to unlock the output rack 51, and then continue to rotate the transmission member 1 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 member 1, and drives the output rack 51 to move in the first direction. The stop between 3 and the third transmission cam 33 drives the output sleeve 3 to rotate counterclockwise synchronously with the transmission member 1, ending the movement of the unlocking rod 6 in the first direction; when the output rack 51 moves to the maximum limit position in the second direction, that is, when the output gear 2 stops with the base 8 in the first direction, the transmission member 1 can be rotated clockwise, and the output sleeve 3 is limited in the circumferential direction through the mutual cooperation between the thread groove 31 and the sliding cam 13, and the mutual cooperation between the second pawl 412 and the second ratchet tooth 342, driving the output sleeve 3 to move in the opposite direction along the first direction. When the transmission member 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 cam 522 can be inserted into the locking recess 611, and the positioning tooth 511 and the limiting tooth 521 can be meshed with each other to complete the locking of the output rack 51 and complete the zeroing setting of the output mechanism 100.

The output sleeve 3 is first driven to move in the first direction, and the unlocking rod 6 is driven to move in the first direction, and the locking protrusion 522 is stopped at 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 from the positioning tooth 511 in the third direction to unlock the output rack 51. Then, the transmission member 1 continues to be rotated counterclockwise. When the second transmission protrusion 21 stops with 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 member 1, and drives the output rack 51 to move in the first direction. At the same time, the abutment between the sliding protrusion 13 and the third transmission protrusion 33 drives the output gear 2 to rotate synchronously with the transmission member 1 counterclockwise. The movable output sleeve 3 rotates counterclockwise synchronously with the transmission member 1, ending the movement of the unlocking rod 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 member 1 rotates against the trend by the first rotation angle and then continues to rotate by the third preset angle, the transmission member 1 can be rotated clockwise, and the output sleeve 3 is limited in the circumferential direction through the mutual cooperation between the thread groove 31 and the sliding protrusion 13, and the mutual cooperation between the second pawl 412 and the second ratchet tooth 342, driving the output sleeve 3 to move in the opposite direction along the first direction.
