[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0041] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are 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 construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0043] In the description of the embodiments of this application, the term "and / or" refers to and encompasses any and all possible combinations of one or more of the associated listed items. The term "and / or" describes an association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects 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 connection remains unchanged. In addition, the directional terms mentioned in the embodiments of the present application, such as "inside" and "outside", etc., are only reference 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 "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising 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 limited by the statement "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In the absence of further restrictions, an element limited by the statement "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0046] In the related art, the transmission device controls components such as phase shifters through the form of gear racks. In order to prevent the transmission from getting stuck, the gear racks must have appropriate tooth side clearance, which results in low control accuracy of the transmission device.

[0047] In order to solve the above technical problems, the present application provides a transmission device. Figure 1 and Figure 2 , Figure 1 A perspective view of a transmission device provided in some embodiments of the present application, Figure 2 Exploded view of a transmission device according to 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 drive assembly 13 .

[0048] The output rack 10 can be used to connect to a 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 spaced apart from each other. Specifically, the first coupling member 111 and the second coupling member 112 are connected to the input shaft 11 and spaced apart from each other in the extending direction of the input shaft 11 .

[0050] The output gear 12 can be engaged with the output rack 10 , and 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, which is in transmission connection with the input shaft 11. Specifically, the transmission connection between the input shaft 11 and the output gear 12 is a detachable transmission connection, i.e., the input shaft 11 and the output gear 12 may not be connected, and the input shaft 11 cannot drive the output gear 12 to rotate. The transmission connection between the input shaft 11 and the output gear 12 can be achieved by components provided on the input shaft 11, or by connecting the input shaft 11 and the output gear 12 together using additional components, and this is not limited in this application.

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

[0053] The drive assembly 13 may include a first output wheel 131, a second output wheel 132, a first drive wheel 133, a second drive wheel 134, and an output shaft 135. The first output wheel 131 and the second output wheel 132 are sleeved on 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 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 can be a hexagonal rod, that is, the cross-section of the output shaft 135 can be hexagonal, and the first output wheel 131 and the second output wheel 132 can have hexagonal holes that match 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 in transmission connection with the first drive wheel 133, thereby driving the first drive wheel 133 to rotate. The second output wheel 132 is in transmission connection with the second drive wheel 134, thereby driving the second drive wheel 134 to rotate. The first output wheel 131 and the first drive wheel 133 may be gears, pulleys, sprockets, etc., and this application does not impose any restrictions on 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.

[0056] The first drive wheel 133 and the second drive wheel 134 are located at opposite ends of the input shaft 11. Specifically, in the longitudinal direction of the input shaft 11, the first drive wheel 133 is located at one end of the input shaft 11 and is not connected to the input shaft 11, and the second drive 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 mating member 136 may be provided on the side of the first drive wheel 133 facing the first coupling member 111, and a second mating member 137 may be provided on the side of the second drive wheel 134 facing the second coupling member 112. Specifically, the first drive wheel 133 may be located on a side of the first coupling member 111 away from the second coupling member 112, and the second drive wheel 134 may be located on a side of the second coupling member 112 away from the first coupling member 111. The first coupling member 111 and the first mating member 136 may mate to connect the first drive wheel 133 to the input shaft 11. The second coupling member 112 and the second mating member 137 may mate to connect the second drive wheel 134 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. Then, 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. There is also no transmission connection between the output gear 12 and the input shaft 11. Then, 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 first drive wheel 133, the output gear 12 can be in driving connection with the input shaft 11, and the first engaging member 111 abuts the first mating member 136. Specifically, when the transmission device 100 changes from the locked state to the first unlocked state, the first output wheel 131 can rotate clockwise, the second output wheel 132 also rotates clockwise, the first drive wheel 133 and the second drive wheel 134 rotate counterclockwise, the input shaft 11 moves toward the first drive wheel 133, the second engaging member 112 disengages from the second mating member 137, and the first engaging member 111 abuts the first mating member 136, allowing the first drive wheel 133 to be in driving connection with the input shaft 11, thereby allowing the input shaft 11 to rotate counterclockwise, thereby enabling the output rack 10 to drive the phase shifter to move in the first direction.

[0061] In the second unlocked state, the input shaft 11 can move toward the second drive wheel 134, the output gear 12 is in driving connection with the input shaft 11, and the second engaging member 112 abuts the second mating member 137. Specifically, when the transmission device 100 changes from the locked state to the second unlocked state, the first output wheel 131 can rotate counterclockwise, causing the second output wheel 132 to also rotate counterclockwise. The first drive wheel 133 and the second drive wheel 134 rotate clockwise, and the input shaft 11 moves toward the second drive wheel 134. The first engaging member 111 disengages from the first mating member 136, and the second engaging member 112 abuts the second mating member 137, allowing the second drive wheel 134 to be in driving connection with the input shaft 11, thereby allowing the input shaft 11 to rotate clockwise, thereby enabling the output rack 10 to 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 achieved by extrusion between the first fitting part 136 and the first coupling part 111 or the second fitting part 137 and the second coupling part 112, and this application does not impose any restrictions on this.

[0063] According to the transmission device 100 of the present embodiment, a first engaging member 136 is provided on the first output wheel 131 to engage with the first engaging member 111, and a second engaging member 137 is provided on the second output wheel 132 to engage with the second engaging member 112. In the first unlocked state, the abutment between the first engaging member 111 and the first engaging member 136 allows the first output wheel 131 to be transmission-connected to the input shaft 11, thereby driving the output rack 10 to move in the first direction. In the second unlocked state, the abutment between the second engaging member 112 and the second engaging member 137 allows the second output wheel 132 to be transmission-connected to the input shaft 11, 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 via the first engaging member 111 and the first engaging member 136, and the second engaging member 112 and the second engaging member 137. The simple structure of the transmission device 100 facilitates simplification of the structure of the transmission device 100, reducing its cost and improving the control accuracy of the transmission device 100.

[0064] See also Figure 2 and Figure 3 , Figure 3Schematic diagram of a first drive wheel provided in 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 an 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 may extend in the same direction as the input shaft 11. The first helical surface 1112 may extend from an edge of the first stop surface 1111 near the first drive wheel 133 in a direction away from the first mating member 136 and toward the first mating member 136.

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

[0066] In the first unlocked state, the first stop surface 1111 can abut and cooperate with the second stop surface 1361, and the first helical surface 1112 can abut and cooperate with the second helical surface 1362. 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, allows the first coupling member 111 and the first mating member 136 to abut in the first unlocked state. Simultaneously, when the locked state transitions to the second unlocked state, the first stop surface 1111 abuts the second helical surface 1362. Through frictional sliding, the first mating member 136 can squeeze the first coupling member 111, thereby driving the input shaft 11 toward the second drive wheel 134.

[0067] This facilitates rapid switching of the transmission device 100 between the locked state, the first unlocked state, and the second unlocked state, thereby further simplifying the structure of the transmission device 100 and thereby reducing the cost of the transmission device 100. Furthermore, the structural layout of the transmission device 100 can be optimized, thereby reducing the size of the transmission device 100.

[0068] For example, the second coupling member 112 may have a third stop surface 1121 and a third helical surface 1122. The third helical surface 1122 may extend from the edge of the third stop surface 1121 in a direction away from the second mating member 137. The second mating member 137 may have a fourth stop surface 1371 and a fourth helical surface 1372. 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 and engages with the fourth stop surface 1371, and the third helical surface 1122 abuts and engages with 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 mating member 137 can abut 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 Schematic diagram of the 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 can 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, which helps 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. The second coupling member 112 may be provided with a positioning boss 1123 that cooperates with the special-shaped groove 115. This facilitates connecting the second coupling member 112 to the input shaft 11, thereby facilitating assembly of the transmission device 100.

In some embodiments, the output gear 12 may have a clutch hole 121. The clutch hole 121 may be provided with internal teeth 122. The transmission device 100 may further include a base 14. The base 14 may be provided with a first fixing bracket 141 and a second fixing bracket 142. The first fixing bracket 141 may be provided with a first guide hole 1411, and the first guide hole 1411 may be provided with a first guide tooth 1412. The second fixing bracket 142 may be provided with a second guide hole 1421. The second guide hole 1421 may be provided with a second guide tooth 1422. The input shaft 11 may be provided with the first guide hole 1411, the second guide hole 1421, and the clutch hole 121. Specifically, the central axes of the first guide hole 1411, the second guide hole 1421, and the clutch hole 121 are collinear, 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 spaced apart from each other. The first clutch tooth 113 and the second clutch tooth 114 are located between the first engaging member 111 and the second engaging member 112. Specifically, the output gear 12 may be located between the first clutch tooth 113 and the second clutch tooth 114. The first clutch tooth 113 and the second clutch tooth 114 may mate 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 engages with the first clutch tooth 113, and the second guide tooth 1422 engages 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 lies within the outline of the first clutch tooth 113, and the orthographic projection of the second guide tooth 1422 on the input shaft 11 lies within the outline of the second clutch tooth 114. There is no transmission connection between the output gear 12 and the input shaft 11. Therefore, when the locked state transitions to the first unlocked state or the second unlocked state, the first guide tooth 1412 and the second guide tooth 1422 can restrict the rotation of the input shaft 11, causing the input shaft 11 to move toward the first drive wheel 133 or the second drive wheel 134.

[0074] In the first unlocked state, the second clutch teeth 114 engage with the internal teeth 122. Specifically, in the first unlocked state, as the input shaft 11 moves toward the first drive wheel 133, the first clutch teeth 113 disengage from the first guide teeth 1412, and the second clutch teeth 114 disengage from the second guide teeth 1422 and mesh with the internal teeth 122, thereby establishing a driving connection between the output gear 12 and the input shaft 11.

[0075] In the second unlocked state, the first clutch teeth 113 engage with the internal teeth 122. Specifically, in the second unlocked state, as the input shaft 11 moves toward the second drive wheel 134, the second clutch teeth 114 disengage from the second guide teeth 1422, and the first clutch teeth 113 disengage from the first guide teeth 1412 and mesh with the internal teeth 122, thereby establishing a driving connection between the output gear 12 and the input shaft 11.

[0076] Thus, the guiding action of the first guide teeth 1412 and the second guide teeth 1422 can limit the rotation of the input shaft 11 when the transmission device 100 switches states, thereby enabling the transmission device 100 to switch states more quickly, thereby improving the displacement accuracy of the transmission device 100 and reducing the manufacturing cost of the transmission device 100. Furthermore, the spacing of the first fixing bracket 141 and the second fixing bracket 142 can prevent interference with the rotation of the output gear 12, allowing for a more reasonable positioning of the output gear 12 and thus 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 within the locking space 143. The locking member 15 can move up and down along the height direction of the locking space 143. Part of the locking member 15 can be located within the locking space 143, and the remaining part can extend from the opening.

[0078] The side of the locking member 15 facing the opening may be provided with a locking protrusion 151. The side of the locking frame 16 facing the opening may be provided with a locking groove 161. The locking protrusion 151 and the locking groove 161 may cooperate with each other. For example, the cross-section of the locking protrusion 151 may be formed into a triangle, and the shape of the locking groove 161 may cooperate with the locking protrusion 151.

[0079] In the locked state, the locking protrusion 151 engages with the locking groove 161. This facilitates transitioning the transmission device 100 from the first unlocked state or the second unlocked state to the locked state. This also ensures that the output gear 12 and the input shaft 11 are not in transmission connection in the locked state, thereby increasing the speed at which the transmission device 100 switches between different states, further optimizing the structure of the transmission device 100 and reducing its manufacturing cost.

[0080] The locking frame 16 is movably mounted on the input shaft 11. One end of the locking frame 16 abuts the first engaging member 111, and the other end abuts the second engaging member 112. Thus, when the transmission device 100 switches from the locked state to the first unlocked state, the second engaging member 112 abuts the locking frame 16, pushing the locking frame 16 toward the first drive wheel 133, thereby disengaging the locking groove 161 from the locking protrusion 151. When the transmission device 100 switches from the locked state to the second unlocked state, the first engaging member 111 abuts the locking frame 16, pushing the locking frame 16 toward the second drive wheel 134, thereby disengaging the locking groove 161 from the locking protrusion 151. Furthermore, when the transmission device 100 switches from the first unlocked state to the locked state, the input shaft 11 can rotate in the opposite direction, for example, half a turn, 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 a 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 cause the locking protrusion 151 to engage with the locking groove 161 when the transmission device 100 is locked.

[0082] In the extension direction of the input shaft 11, the two opposing walls of the locking groove 161 serve as guide slopes. Specifically, when the transmission device 100 transitions from the locked state to the first unlocked state or the second unlocked state, the guide slopes allow the guide protrusion to slide away from the locking groove 161, and the locking frame 16 presses against the locking member 15, thereby compressing the elastic member 152. This configuration simplifies the structure and helps reduce 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 guide portion 154. The connecting portion 153 is movably connected to the input shaft 11. The guide portion 154 is connected to the connecting portion 153 and extends in the same direction as the input shaft 11. The base 14 may be provided with a guide groove 146 that cooperates with the guide portion 154. Thus, through the cooperation between the guide portion 154 and the guide groove 146, the locking frame 16 can move along the extension direction of the guide groove 146, thereby limiting the movement direction of the locking frame 16, providing a guiding function, and further ensuring the reliability of the movement of the locking frame 16.

[0084] Exemplarily, the guide groove 146 can 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 Figure 11 , Figure 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. By providing the stopper, the moving distance of the rack can be limited, 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 sliding groove may be provided on the side of the output rack 10 away from the output gear 12. First locking teeth 101 may be provided on both sides of the sliding 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 sliding groove. The damping plate 17 is arranged in the mounting groove 145 and abuts against the sliding groove. As a result, the damping plate 17 can slide and rub with the sliding groove at the bottom of the output rack 10, thereby generating a certain damping force, so that the output can be smoother during adjustment. At the same time, the assembly gap can be quantified, which makes it easy to compensate during program control.

[0089] The present application also provides an antenna assembly including a phase shifter and the aforementioned transmission device 100.
