[0040] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0041] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0043] In the description of the embodiments of the present application, the term "and / or" refers to and covers any and all possible combinations of one or more of the associated listed items. The term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in the present application generally indicates that the associated objects before and after are in an "or" relationship.

[0044] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. In addition, the directional terms mentioned in the embodiments of the present application, such as "inside", "outside", etc., are only references to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0045] In the description of the embodiments of the present application, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0046] In the related art, the transmission device controls the phase shifter and other components through the form of gear racks, and the gear racks must have appropriate tooth side clearance to prevent the transmission from getting stuck, so the control accuracy of the transmission device is low.

[0047] In order to solve the above technical problems, the present application provides a transmission device. Figure 1 and Figure 2 , Figure 1 A three-dimensional diagram of a transmission device provided in some embodiments of the present application, Figure 2 The exploded view of the transmission device provided in some embodiments of the present application. The transmission device 100 includes an output rack 10 , an input shaft 11 , an output gear 12 and a driving assembly 13 .

[0048] The output rack 10 can be used to connect the phase shifter. When the output rack 10 moves, the phase shifter can be driven to move.

[0049] The input shaft 11 may have a first coupling member 111 and a second coupling member 112 disposed at intervals. Specifically, the first coupling member 111 and the second coupling member 112 are connected to the input shaft 11 and are disposed at intervals in the extending direction of the input shaft 11.

[0050] The output gear 12 can mesh with the output rack 10, so the rotation of the output gear 12 can drive the output rack 10 to move, thereby driving the phase shifter to move.

[0051] The input shaft 11 is provided with an output gear 12, and the output gear 12 can be connected to the input shaft 11 by transmission. Specifically, the transmission connection between the input shaft 11 and the output gear 12 is a detachable transmission connection, that is, there may be no connection between the input shaft 11 and the output gear 12, and the input shaft 11 cannot drive the output gear 12 to rotate. The input shaft 11 and the output gear 12 can have a transmission connection, which can be achieved by components arranged on the input shaft 11, or by connecting the input shaft 11 and the output gear 12 together by additional components, and the present application does not limit this.

[0052] The output gear 12 may be located between the first coupling member 111 and the second coupling member 112 , which facilitates the first coupling member 111 and the second coupling member 112 to cooperate with other components, thereby making the structural layout of the transmission device 100 more reasonable.

[0053] The driving assembly 13 may include a first output wheel 131, a second output wheel 132, a first driving wheel 133, a second driving wheel 134 and an output shaft 135. The first output wheel 131 and the second output wheel 132 are sleeved at both ends of the output shaft 135. Specifically, the first output wheel 131 is connected to one end of the output shaft 135, and the second output wheel 132 is connected to the other end of the output shaft 135. When the output shaft 135 rotates, the first output wheel 131 and the second output wheel 132 can rotate with the rotation of the output shaft 135, that is, the first output wheel 131 and the second output wheel 132 can rotate synchronously.

[0054] Exemplarily, the output shaft 135 may be a hexagonal rod, that is, the cross-section of the output shaft 135 may be hexagonal, and the first output wheel 131 and the second output wheel 132 may have hexagonal holes matching the shape of the output shaft 135, so that the output shaft 135 can drive the first output wheel 131 and the second output wheel 132 to rotate.

[0055] The first output wheel 131 is connected to the first drive wheel 133 by transmission, and the first output wheel 131 can drive the first drive wheel 133 to rotate. The second output wheel 132 is connected to the second drive wheel 134 by transmission, and the second output wheel 132 can drive the second drive wheel 134 to rotate. Among them, the first output wheel 131 and the first drive wheel 133 can be gears, pulleys, sprockets, etc., and this application does not limit this. In the following description, the first output wheel 131, the first drive wheel 133, the second output wheel 132, and the second drive wheel 134 are gears for example.

[0056] The first driving wheel 133 and the second driving wheel 134 are located at opposite ends of the input shaft 11. Specifically, in the length direction of the input shaft 11, the first driving wheel 133 is located at one end of the input shaft 11 and is not connected to the input shaft 11, and the second driving wheel 134 is located at the other end of the input shaft 11 and is not connected to the input shaft 11.

[0057] A first matching piece 136 may be provided on the side of the first driving wheel 133 facing the first coupling member 111, and a second matching piece 137 may be provided on the side of the second driving wheel 134 facing the second coupling member 112. Specifically, the first driving wheel 133 may be located on the side of the first coupling member 111 away from the second coupling member 112, and the second driving wheel 134 may be located on the side of the second coupling member 112 away from the first coupling member 111. The first coupling member 111 and the first matching piece 136 may cooperate with each other, so that the first driving wheel 133 may be connected to the input shaft 11. The second coupling member 112 and the second matching piece 137 may cooperate with each other, so that the second driving wheel 134 may be connected to the input shaft 11.

[0058] The transmission 100 can have a locked state, a first unlocked state, and a second unlocked state.

[0059] In the locked state, the first coupling member 111 and the first matching member 136 are disengaged, and the second coupling member 112 and the second matching member 137 are disengaged, so that the first driving wheel 133 cannot drive the input shaft 11 to rotate, and the second driving wheel 134 cannot drive the input shaft 11 to rotate, and there may be no transmission connection between the output gear 12 and the input shaft 11, so that the output gear 12 cannot drive the output rack 10 to move, so that the transmission device 100 as a whole can be in a locked state.

[0060] In the first unlocked state, the input shaft 11 can move toward the direction close to the first driving wheel 133, the output gear 12 can be connected to the input shaft 11, and the first coupling member 111 abuts against the first matching member 136. Specifically, in the process of the transmission device 100 changing from the locked state to the first unlocked state, the first output wheel 131 can rotate in the clockwise direction, the second output wheel 132 also rotates in the clockwise direction, the first driving wheel 133 and the second driving wheel 134 rotate in the counterclockwise direction, the input shaft 11 moves toward the direction close to the first driving wheel 133, the second coupling member 112 is disengaged from the second matching member 137, the first coupling member 111 abuts against the first matching member 136, so that the first driving wheel 133 can be connected to the input shaft 11, so that the input shaft 11 can rotate in the counterclockwise direction, and then the output rack 10 can drive the phase shifter to move in the first direction.

[0061] In the second unlocked state, the input shaft 11 can move toward the direction close to the second drive wheel 134, the output gear 12 is in transmission connection with the input shaft 11, and the second coupling member 112 abuts against the second matching member 137. Specifically, in the process of the transmission device 100 changing from the locked state to the second unlocked state, the first output wheel 131 can rotate in the counterclockwise direction, and the second output wheel 132 also rotates in the counterclockwise direction, the first drive wheel 133 and the second drive wheel 134 rotate in the clockwise direction, the input shaft 11 moves toward the direction close to the second drive wheel 134, the first coupling member 111 is disengaged from the first matching member 136, the second coupling member 112 abuts against the second matching member 137, so that the second drive wheel 134 can be in transmission connection with the input shaft 11, so that the input shaft 11 can rotate in the clockwise direction, and then the output rack 10 can drive the phase shifter to move in the second direction.

[0062] It should be noted that the movement of the input shaft 11 can be controlled by additional components, or can be achieved by extrusion between the first mating piece 136 and the first combining piece 111 or the second mating piece 137 and the second combining piece 112, and the present application does not impose any restrictions on this.

[0063] According to the transmission device 100 of the embodiment of the present application, by providing a first matching piece 136 matching with the first coupling piece 111 on the first output wheel 131, and providing a second matching piece 137 matching with the second coupling piece 112 on the second output wheel 132, in the first unlocked state, the first output wheel 131 can be connected to the input shaft 11 through the abutment between the first coupling piece 111 and the first matching piece 136, thereby driving the output rack 10 to move in the first direction. In the second unlocked state, the second output wheel 132 can be connected to the input shaft 11 through the abutment between the second coupling piece 112 and the second matching piece 137, thereby driving the output rack 10 to move in the second direction. Thus, the transmission device 100 can be switched between the locked state, the first unlocked state, and the second unlocked state through the first coupling piece 111 and the first matching piece 136, the second coupling piece 112 and the second matching piece 137, and the structure is simple, which is conducive to simplifying the structure of the transmission device 100 and making the cost of the transmission device 100 lower. At the same time, it is also conducive to improving the control accuracy of the transmission device 100.

[0064] See also Figure 2 and Figure 3 , Figure 3Schematic diagram of the first driving wheel provided for some embodiments of the present application. In some embodiments, the first coupling member 111 may have a first stop surface 1111 and a first helical surface 1112. The first helical surface 1112 may extend from the edge of the first stop surface 1111 in a direction away from the first mating member 136. Specifically, the first stop surface 1111 may face the input shaft 11, and the extension direction may be the same as the extension direction of the input shaft 11, and the first helical surface 1112 may extend from the edge of the first stop surface 1111 close to the first driving wheel 133 in a direction away from the first mating member 136, and toward the first mating member 136.

[0065] The first matching member 136 may have a second stop surface 1361 and a second helical surface 1362. The second helical surface 1362 may extend from the edge of the second stop surface 1361 in a direction away from the first coupling member 111. Specifically, the second stop surface 1361 may face the input shaft 11, and the extending direction may be the same as the extending direction of the input shaft 11, and the second helical surface 1362 may extend from the edge of the second stop surface 1361 away from the first driving wheel 133 in a direction close to the first driving wheel 133, and toward the first driving wheel 133.

[0066] In the first unlocked state, the first stop surface 1111 can be abutted with the second stop surface 1361, and the first helical surface 1112 can be abutted with the second helical surface 1362. Through the cooperation between the first stop surface 1111 and the second stop surface 1361, and the first helical surface 1112 and the second helical surface 1362, the first coupling member 111 and the first matching member 136 can be abutted in the first unlocked state. At the same time, when the locked state is changed to the second unlocked state, the first stop surface 1111 and the second helical surface 1362 are abutted, and through friction sliding, the first matching member 136 can squeeze the first coupling member 111, thereby driving the input shaft 11 to move in the direction close to the second driving wheel 134.

[0067] Thus, the transmission device 100 can be quickly switched between the locked state, the first unlocked state and the second unlocked state, thereby further simplifying the structure of the transmission device 100, thereby helping to reduce the cost of the transmission device 100. At the same time, the structural layout of the transmission device 100 can be optimized, thereby helping to reduce the volume of the transmission device 100.

[0068] Exemplarily, the second coupling member 112 may have a third stop surface 1121 and a third helical surface 1122, and the third helical surface 1122 may extend from the edge of the third stop surface 1121 in a direction away from the second matching member 137. The second matching member 137 may have a fourth stop surface 1371 and a fourth helical surface 1372, and the fourth helical surface 1372 may extend from the edge of the fourth stop surface 1371 in a direction away from the second coupling member 112. In the second unlocked state, the third stop surface 1121 abuts against the fourth stop surface 1371, and the third helical surface 1122 abuts against the fourth helical surface 1372. Thus, through the cooperation between the third stop surface 1121 and the fourth stop surface 1371, and the third helical surface 1122 and the fourth helical surface 1372, the second coupling member 112 and the second matching member 137 may abut against each other in the second unlocked state. At the same time, when the locked state is changed to the first unlocked state, the third stop surface 1121 abuts against the fourth spiral surface 1372. Through friction sliding, the second matching member 137 can squeeze the second coupling member 112, thereby driving the input shaft 11 to move toward the direction close to the first driving wheel 133.

[0069] See also Figure 4 and Figure 5 , Figure 4 A schematic diagram of an input shaft provided in some embodiments of the present application, Figure 5 Schematic diagram of the second coupling member provided for some embodiments of the present application. In some embodiments, the second coupling member 112 is detachably connected to the input shaft 11. The first coupling member 111 and the input shaft 11 may be fixedly connected or detachably connected. When the first coupling member 111 and the input shaft 11 are fixedly connected, the detachable connection between the second coupling member 112 and the input shaft 11 facilitates the assembly of the first drive wheel 133 and the second drive wheel 134, thereby helping to reduce the difficulty of assembly. At the same time, it is also convenient to replace and repair the second coupling member 112, thereby helping to improve the maintainability of the transmission device 100.

[0070] For example, the input shaft 11 may have a special-shaped groove 115, which may extend to the end of the input shaft 11 away from the first coupling member 111, and the second coupling member 112 may be provided with a positioning boss 1123 that matches the special-shaped groove 115. Thus, it is convenient to connect the second coupling member 112 to the input shaft 11, which is conducive to improving the assembly speed of the transmission device 100.

A second guide hole 1421 may be provided on the second fixing frame 142. A second guide tooth 1422 may be provided in the second guide hole 1421. The input shaft 11 may be provided with a first guide hole 1411, a second guide hole 1421 and a clutch hole 121. Specifically, the central axes of the first guide hole 1411, the second guide hole 1421 and the clutch hole 121 are on the same straight line, and the input shaft 11 is rotatably provided with the first guide hole 1411, the second guide hole 1421 and the clutch hole 121.

[0072] The input shaft 11 may have a first clutch tooth 113 and a second clutch tooth 114 which are spaced apart. The first clutch tooth 113 and the second clutch tooth 114 are located between the first coupling member 111 and the second coupling member 112. Specifically, the output gear 12 may be located between the first clutch tooth 113 and the second clutch tooth 114, and the first clutch tooth 113 and the second clutch tooth 114 may be matched with the first guide tooth 1412, the second guide tooth 1422 or the inner tooth 122.

[0073] In the locked state, the first guide tooth 1412 cooperates with the first clutch tooth 113, and the second guide tooth 1422 cooperates with the second clutch tooth 114. Specifically, in the locked state, the orthographic projection of the first guide tooth 1412 on the input shaft 11 is located within the profile of the first clutch tooth 113, and the orthographic projection of the second guide tooth 1422 on the input shaft 11 is located within the profile of the second clutch tooth 114, and there is no transmission connection between the output gear 12 and the input shaft 11. Therefore, when the locked state is changed to the first unlocked state or the second unlocked state, the first guide tooth 1412 and the second guide tooth 1422 can limit the rotation of the input shaft 11, so that the input shaft 11 moves toward the direction close to the first drive wheel 133 or the second drive wheel 134.

[0074] In the first unlocked state, the second clutch teeth 114 are matched with the inner teeth 122. Specifically, since the input shaft 11 moves toward the direction close to the first driving wheel 133 in the first unlocked state, the first clutch teeth 113 are disengaged from the first guide teeth 1412, and the second clutch teeth 114 are disengaged from the second guide teeth 1422 and meshed with the inner teeth 122, so that the output gear 12 is connected to the input shaft 11 in a transmission manner.

[0075] In the second unlocked state, the first clutch teeth 113 are matched with the inner teeth 122. Specifically, since the input shaft 11 moves toward the direction close to the second driving wheel 134 in the second unlocked state, the second clutch teeth 114 are disengaged from the second guide teeth 1422, and the first clutch teeth 113 are disengaged from the first guide teeth 1412 and mesh with the inner teeth 122, so that the output gear 12 is connected to the input shaft 11 in a transmission manner.

[0076] Thus, through the guiding effect of the first guide teeth 1412 and the second guide teeth 1422, the rotation of the input shaft 11 can be limited when the transmission device 100 switches states, so that the transmission device 100 can switch states more quickly, which is beneficial to improving the displacement accuracy of the transmission device 100 and reducing the manufacturing cost of the transmission device 100. At the same time, the first fixing frame 141 and the second fixing frame 142 are arranged at intervals to avoid interference with the rotation of the output gear 12, so that the position setting of the output gear 12 can be more reasonable, thereby optimizing the structural layout of the transmission device 100.

[0077] Please continue reading Figure 7-10 In some embodiments, the transmission device 100 may further include a locking member 15 and a locking frame 16. The base 14 may have a locking space 143. The top side of the locking space 143 may have an opening. The locking member 15 is movably disposed in the locking space 143. The locking member 15 may move up and down along the height direction of the locking space 143, a portion of the locking member 15 may be located in the locking space 143, and the remaining portion may extend from the opening.

[0078] The locking member 15 may be provided with a locking protrusion 151 on one side facing the opening. The locking frame 16 may have a locking groove 161 on one side facing the opening. The locking protrusion 151 and the locking groove 161 may match each other. For example, the cross section of the locking protrusion 151 may be formed as a triangle, and the shape of the locking groove 161 may match that of the locking protrusion 151.

[0079] In the locked state, the locking protrusion 151 cooperates with the locking groove 161. Thus, it is convenient for the transmission device 100 to change from the first unlocked state or the second unlocked state to the locked state. At the same time, it can also ensure that the output gear 12 in the locked state has no transmission connection with the input shaft 11, thereby increasing the speed of switching different states of the transmission device 100, thereby optimizing the structure of the transmission device 100, and helping to reduce the manufacturing cost of the transmission device 100.

[0080] The locking frame 16 is movably sleeved on the input shaft 11. One end of the locking frame 16 abuts against the first coupling member 111, and the other end abuts against the second coupling member 112. Therefore, when the transmission device 100 changes from the locked state to the first unlocked state, the second coupling member 112 can abut against the locking frame 16, and can push the locking frame 16 to move in the direction close to the first driving wheel 133, so that the locking groove 161 and the locking protrusion 151 can be disengaged. When the transmission device 100 changes from the locked state to the second unlocked state, the first coupling member 111 can abut against the locking frame 16, and can push the locking frame 16 to move in the direction close to the second driving wheel 134, so that the locking groove 161 and the locking protrusion 151 can be disengaged. In addition, when the transmission device 100 changes from the first unlocked state to the locked state, the input shaft 11 can rotate in the opposite direction, for example, it can rotate half a circle to reset the locking frame 16 and the locking member 15.

[0081] Please continue reading Figure 7-10 In some embodiments, an elastic member 152 may be provided on one side of the locking member 15 away from the locking protrusion 151. The elastic member 152 may abut against the bottom wall of the locking space 143. Thus, the elastic member 152 may make the locking protrusion 151 match with the locking groove 161 when the transmission device 100 is in the locked state.

[0082] In the extension direction of the input shaft 11, the two opposite side walls of the locking groove 161 are guide slopes. Specifically, when the transmission device 100 changes from the locked state to the first unlocked state or the second unlocked state, the guide slopes allow the guide protrusion to slide in a direction away from the locking groove 161, and the locking frame 16 presses the locking member 15, so that the elastic member 152 is squeezed. Such a configuration is simple in structure and is conducive to reducing the manufacturing cost of the transmission device 100.

[0083] Please continue reading Figure 7-10In some embodiments, the locking frame 16 may include a connecting portion 153 and a guiding portion 154, wherein the connecting portion 153 is movably connected to the input shaft 11. The guiding portion 154 is connected to the connecting portion 153, and the extending direction is the same as the extending direction of the input shaft 11. A guiding groove 146 that matches the guiding portion 154 may be provided on the base 14. Thus, through the cooperation between the guiding portion 154 and the guiding groove 146, the locking frame 16 can move along the extending direction of the guiding groove 146, thereby limiting the moving direction of the locking frame 16, playing a guiding role, and further ensuring the reliability of the movement of the locking frame 16.

[0084] Exemplarily, the guide groove 146 may be located above the opening. This arrangement facilitates the arrangement of the locking groove 161 and can optimize the structure of the locking frame 16.

[0085] Exemplarily, the locking frame 16 may have an avoidance hole, and the output gear 12 may be located in the avoidance hole. This arrangement can prevent the locking frame 16 from interfering with the rotation of the output gear 12.

[0086] See also Figure 7 and Fig.11 , Fig.11 Schematic diagram of a locking member provided for some embodiments of the present application. In some embodiments, a first locking tooth 101 may be provided on the side of the rack away from the output gear 12. A rack through hole 144 may be provided on the base 14. A connecting hole 155 may be provided on the locking member 15. A second locking tooth 156 may be provided on the bottom wall of the connecting hole 155. The rack passes through the rack through hole 144 and the connecting hole 155. In the locked state, the first locking tooth 101 and the second locking tooth 156 are engaged. Thus, the rack through hole 144 can guide the movement of the rack, and the rack can also move more smoothly. At the same time, through the engagement of the first locking tooth 101 and the second locking tooth 156, the locking member can lock the rack, thereby further ensuring the locking effect of the rack in the locked state.

[0087] For example, a stopper may be provided on one side of the rack. The stopper may limit the moving distance of the rack, thereby making the transmission of the transmission device 100 more reliable.

[0088] Please continue reading Figure 7 and Figure 8In some embodiments, the transmission device 100 may further include a damping plate 17. A slide groove may be provided on one side of the output rack 10 away from the output gear 12. The first locking teeth 101 may be provided on both sides of the slide groove. The bottom wall of the rack through hole 144 may have a mounting groove 145, and the mounting groove 145 is directly opposite to the slide groove. The damping plate 17 is arranged in the mounting groove 145 and abuts against the slide groove. As a result, the damping plate 17 can slide and rub with the slide groove at the bottom of the output rack 10, so that a certain damping force can be generated, so that the output can be smoother during adjustment. At the same time, the assembly gap can be quantified, so that it is easy to compensate during program control.

[0089] The embodiment of the present application also provides an antenna assembly, including a phase shifter and the above-mentioned transmission device 100.
