Description

Technical Field

[0001] The present application relates to the technical field of antennas, and in particular to a phase shift transmission device and an antenna. Background Art

[0002] Antennas, as devices for transmitting or receiving electromagnetic waves, are also the components used by radio equipment to transmit and receive electromagnetic waves. They are commonly used in communications, broadcasting, radar, television, satellite communications, and other fields. The transmission mechanism in antennas is generally used to control the movement of components such as phase shifters to achieve phase adjustment, thereby enabling rapid optimization of antenna coverage networks. Currently, the transmission input interface of a phase shifter often uses an external transmission rod at the end. The transmission rod is connected to the phase shifter's internal phase shifter medium, and phase adjustment is achieved by the extension and contraction of the transmission rod, which drives the phase shifter medium.

[0003] However, when designing an antenna, in addition to considering the length of the phase shifter itself, it is also necessary to reserve the length space required for the transmission rod to be extended and retracted. This length space will increase as the adjustment stroke of the phase shifter increases, which will occupy too much layout space in the length direction of the phase shifter. This will undoubtedly increase the difficulty of the internal layout of the antenna, resulting in the antenna being too long and not conducive to miniaturization. Summary of the Invention

[0004] Based on this, it is necessary to provide a phase shift transmission device and antenna to address the problem that the antenna occupies too much layout space in the length direction, the internal layout of the antenna is difficult, and it is not conducive to the miniaturization design of the antenna.

[0008] A power input mechanism is movably disposed on the transmission box and is in transmission connection with the transmission mechanism, and is used to be connected to a power output mechanism of the phase shifter.

[0009] The phase-shifting transmission device of the present invention is used to be assembled and cooperated with the phase shifter to transmit power to the phase-shifting medium inside the phase shifter, thereby driving the phase-shifting medium to move and achieve phase adjustment. Specifically, when in use, the transmission box is installed and stacked in the height direction of the phase shifter, and the power input mechanism is connected to the power output mechanism of the phase shifter. The power output mechanism outputs driving force to the power input mechanism, which in turn drives the transmission mechanism to move. Finally, the transmission mechanism drives the phase-shifting medium inside the phase shifter to move, thereby achieving phase adjustment. Compared with the prior art, the phase-shifting transmission device of the present invention is installed in an integral stacked manner in the height direction of the phase shifter, thereby effectively saving layout space in the length direction of the phase shifter, reducing the difficulty of internal antenna layout, and being more conducive to achieving a miniaturized antenna design.

[0056] 2 , which shows a phase-shifting transmission device 10 according to an embodiment of the present application, including a transmission box 11 , a transmission mechanism 12 , and a power input mechanism 13 .

[0057] The transmission box 11 is used to be stacked on the height direction of the phase shifter 20. For example, taking the phase shifter 20 in a rectangular parallelepiped shape as an example, the phase shifter 20 has a length direction, a width direction and a height direction. Figure 1 In the figure, the length direction may refer to the X-axis direction, the width direction may refer to the Y-axis direction, and the height direction may refer to the Z-axis direction.

[0058] Please continue reading Figure 2 and Figure 3 The transmission mechanism 12 is arranged inside the transmission box 11, and the transmission mechanism 12 is used to be connected to the phase shifting medium inside the phase shifter 20; the power input mechanism 13 is movably arranged in the transmission box 11 and is connected to the transmission mechanism 12, and the power input mechanism 13 is used to be connected to the power output mechanism of the phase shifter 20.

[0059] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: the phase-shifting transmission device 10 of this solution is used to be assembled and cooperated with the phase shifter 20 to transmit power to the phase-shifting medium inside the phase shifter 20, driving the phase-shifting medium to move and achieve phase adjustment. Specifically, during use, the transmission case 11 is installed and stacked in the height direction of the phase shifter 20, and the power input mechanism 13 is connected to the power output mechanism of the phase shifter 20. The power output mechanism outputs driving force to the power input mechanism 13, which in turn drives the transmission mechanism 12 to move. Ultimately, the transmission mechanism 12 drives the phase-shifting medium inside the phase shifter 20 to move, thereby achieving phase adjustment. Compared with the prior art, the phase-shifting transmission device 10 of this solution is installed as a whole in a stacked manner in the height direction of the phase shifter 20, thereby effectively saving layout space in the length direction of the phase shifter 20, reducing the layout difficulty inside the antenna 100, and further facilitating a miniaturized design of the antenna 100.

[0060] Please continue reading Figures 2 to 5In one embodiment, the power input mechanism 13 includes a power input rack 131, the transmission mechanism 12 includes a gear mechanism, the power input rack 131 is reciprocatingly arranged in the transmission box 11, the gear mechanism is rotatably arranged in the transmission box 11, the gear mechanism is engaged with the power input rack 131, and the gear mechanism is used to engage with the rack of the phase-shifting medium.

[0061] Structurally, the length of the power input rack 131 aligns with the length of the phase shifter 20, and the reciprocating direction of the power input rack 131 also aligns with the length of the phase shifter 20. During operation, a power output mechanism is connected to the power input rack 131 to output telescopic power to the power input rack 131, causing the power input rack 131 to reciprocate linearly. For example, when the power input rack 131 moves in one direction (e.g., the +X-axis direction), the drive gear mechanism rotates clockwise, driving the phase shifting medium in a first predetermined direction, thereby achieving phase adjustment. Similarly, when the power input rack 131 moves in the opposite direction (e.g., the -X-axis direction), the phase shifting medium correspondingly moves in a second predetermined direction opposite the first predetermined direction, similarly achieving phase adjustment.

[0062] By means of the sequential meshing transmission structure of the power input rack 131, the gear mechanism and the rack of the phase-shifting medium, it is possible to ensure smooth and reliable power transmission, the displacement accuracy of the phase shifter 20, and thus the phase adjustment accuracy; in addition, compared with the traditional external transmission rod form, the overall transmission structure is more compact and occupies less space.

[0063] Please continue reading Figures 2 to 5 Furthermore, in one embodiment, the transmission box 11 includes a box body 111 and a box cover 112. The box body 111 and the box cover 112 are assembled and enclosed to form a receiving cavity. The gear mechanism is arranged in the receiving cavity. The box body 111 is provided with an extension port, and part of the gear mechanism extends from the extension port to engage with the rack of the phase-shifting medium.

[0064] The transmission case 11 is designed as a separate housing 111 and cover 112, facilitating installation of the gear mechanism within the housing and subsequent disassembly and maintenance. The gear mechanism's volume overlaps with the transmission case 11, reducing the size of the phase-shifting transmission device 10 and achieving a compact design. The gear mechanism extends from the extension opening of the housing 111, allowing it to directly engage with the rack of the phase-shifting medium after the transmission case 11 is installed on the phase shifter 20, improving assembly convenience.

[0065] Please continue reading Figure 11 and Figure 13In one embodiment, one of the housing 111 and the lid 112 is provided with a positioning hole 111c, and the other of the housing 111 and the lid 112 is provided with a positioning post 112a, which is inserted into the positioning hole 111c. During processing, after the gear mechanism is installed in the housing 111, the lid 112 and the housing 111 are assembled. At this time, the positioning post 112a is aligned and inserted into the positioning hole 111c to achieve pre-positioning of the housing 112 and the housing 111.

[0066] Please continue reading Figure 2 ,as well as Figure 11 and Figure 13 Furthermore, one of the box body 111 and the box cover 112 is provided with a latch 111d, and the other of the box body 111 and the box cover 112 is provided with a buckle 112b. The latch 111d engages with the buckle 112b. When the box cover 112 and the box body 111 are assembled, the latch 111d automatically engages with the buckle 112b to form a physical stop, securely fixing the box cover 112 and the box body 111.

[0067] Please continue reading Figures 1 to 5 , Figure 8 , Figure 9 and Figure 15 More specifically, in the above embodiment, the gear mechanism includes a transmission gear 121 and an output gear 122. The transmission gear 121 is meshed with the power input rack 131 and the output gear 122 respectively. The extension port includes a first extension port 111a and a second extension port 111b that are oppositely arranged. The phase-shifting medium includes a first phase-shifting medium 22 and a second phase-shifting medium 23. The output gear 122 extends from the first extension port 111a to engage with the rack of the first phase-shifting medium 22, and the transmission gear 121 extends from the second extension port 111b to engage with the rack of the second phase-shifting medium 23.

[0068] During operation, the reciprocating power input rack 131 first drives the transmission gear 121 to rotate, which then synchronously drives the output gear 122 to rotate. On this basis, the output gear 122 and the transmission gear 121 simultaneously drive the first phase-shifting medium 22 and the second phase-shifting medium 23 to move synchronously and in the same direction, respectively, to achieve phase adjustment of the phase shifter 20. This rack and pinion transmission structure has a short power transmission path, thereby greatly improving the adjustment efficiency of the phase shifter 20.

[0069] Furthermore, the transmission gear 121 includes a first gear 121a and a second gear 121b that are coaxially connected, the first gear 121a is engaged with the power input rack 131, the second gear 121b is engaged with the output gear 122, and the second gear 121b extends from the second extension port 111b to engage with the rack of the second phase-shifting medium 23; wherein the diameter of the first gear 121a is larger than the diameter of the second gear 121b.

[0070] On the one hand, the transmission gear 121 is designed to be a first gear 121a and a second gear 121b that are coaxially connected, so that the first gear 121a is specifically used to mesh with the power input rack 131, while the second gear 121b is meshed with the output gear 122 and the rack of the second phase-shifting medium 23. In other words, the transmission gear 121 has the ability to simultaneously connect multiple components and realize power transmission; on the other hand, the diameter of the first gear 121a is larger than the diameter of the second gear 121b, so that when the rotational power is transmitted from the first gear 121a to the second gear 121b, the speed can be reduced while the torque is increased. In other words, the push-pull force output to the first phase-shifting medium 22 and the second phase-shifting medium 23 is increased, while the output stroke is reduced, which helps to achieve higher displacement precision control and improve the adjustment accuracy of the phase shifter 20.

[0071] In addition, by changing the number of teeth of the first gear 121a and / or the second gear 121b, the speed ratio of the gear mechanism can be changed to achieve amplification or reduction of the output stroke to meet different operating conditions.

[0072] Please continue reading Figure 15 Furthermore, based on the above embodiment, a clutch tooth 121c is provided on the end surface of the second gear 121b away from the first gear 121a. The clutch tooth 121c is provided to play a clutch role when plugged into the phase shifting medium of the phase shifter 20.

[0073] Please continue reading Figures 2 to 5 In another embodiment, the power input mechanism 13 further includes a clamping member 132 and a transmission rod 133. The transmission rod 133 is fixedly connected to the power input rack 131 via the clamping member 132. Thus, the transmission rod 133 is integrally assembled and fixed to the power input rack 131 via the clamping member 132. The mounting structure is simple, and the clamping member 132 can effectively limit the relative freedom of movement of the transmission rod 133 and the power input rack 131.

[0074] During use, the transmission rod 133 is first connected to the power output mechanism of the phase shifter 20. The telescopic power output by the power output mechanism first acts on the transmission rod 133. Then, the transmission rod 133 drives the power input rack 131 to move synchronously back and forth along the length direction of the phase shifter 20 through the clamping member 132, thereby realizing the power input rack 131 transmitting the driving force to the gear mechanism, and finally the gear mechanism drives the first phase shifting medium 22 and the second phase shifting medium 23 to move synchronously in the same direction.

[0075] Please continue reading Figure 2 , Figure 3 and Figure 10During operation, in order to improve the smoothness of the reciprocating movement of the transmission rod 133 and the power input rack 131, in one embodiment, the box body 111 is provided with a first through hole 111e, and the power input rack 131 can be reciprocatingly slidably penetrated in the first through hole 111e.

[0076] Furthermore, the box body 111 is further provided with a second through hole 111 f , and the transmission rod 133 is reciprocally slidably inserted into the second through hole 111 f .

[0077] It is easy to understand that the wall of the first through hole 111e is in sliding contact with the power input rack 131 to guide the power input rack 131 and stabilize the moving position and posture of the power input rack 131; similarly, the wall of the second through hole 111f is in sliding contact with the transmission rod 133 to guide the transmission rod 133 and stabilize the moving position and posture of the transmission rod 133.

[0078] It should be noted that the housing 111 has a first through-hole 111e and a second through-hole 111f on two opposing side walls along the length of the phase shifter 20. In other words, the housing 111 has two first through-holes 111e and two second through-holes 111f spaced apart and opposed to each other. The power input rack 131 is inserted through both first through-holes 111e, and the transmission rod 133 is inserted through both second through-holes 111f. These two first through-holes 111e and two second through-holes 111f effectively restrict the position and posture of the power input rack 131 and the transmission rod 133, preventing them from swinging during reciprocating movement and affecting transmission accuracy.

[0079] Please continue reading Figure 2 , Figure 3 and Figure 14 In an optional embodiment, the clamping member 132 is provided with a first clamping slot 132a and a second clamping slot 132b. Considering that the transmission rod 133 and the power input rack 131 are stacked in the height direction of the phase shifter 20, the first clamping slot 132a and the second clamping slot 132b are also stacked in the height direction of the phase shifter 20. In other words, the first clamping slot 132a and the second clamping slot 132b are formed on opposite sides of the clamping member 132.

[0080] For example, the first slot 132a is located below the second slot 132b, so that the power input rack 131 can also be arranged below the transmission rod 133 and also located on one side of the horizontal direction of the transmission box 11, thereby facilitating the engagement and installation of the power input rack 131 with the gear mechanism.

[0081] The groove wall of the first slot 132a is provided with a first limiting protrusion, and the groove wall of the second slot 132b is provided with a second limiting protrusion. The power input rack 131 is clamped in the first slot 132a, and the first clamping port 131a of the power input rack 131 is clamped with the first limiting protrusion. The transmission pull rod 133 is clamped in the second slot 132b, and the second clamping port 133a of the transmission pull rod 133 is clamped with the second limiting protrusion. On the one hand, with the help of the clamping effect of the groove side wall, the power input rack 131 and the transmission rod 133 can be basically clamped and fixed; on the other hand, with the help of the first limiting protrusion and the first clamping groove 132a and the second limiting protrusion and the second clamping groove 132b, the freedom of movement of the power input rack 131 and the transmission rod 133 can be further limited, preventing relative movement and looseness between the power input rack 131 and the clamping part 132 and the transmission rod 133 and the clamping part 132, thereby affecting the transmission efficiency and accuracy.

[0082] For example, the clamping member 132 is made of a material such as hard plastic or metal with a certain elasticity, and has good connection reliability and reusability.

[0083] The first card slot 132a and the second card slot 132b are long through-slot structures, which on the one hand facilitate the clamping and installation of the power input rack 131 and the transmission pull rod 133, and on the other hand can also increase the clamping area between the clamping member 132 and the power input rack 131 and the transmission pull rod 133, thereby improving the clamping firmness.

[0084] Please continue reading Figure 6 , Figure 7 and Figure 12 Before the phase shift transmission device 10 is installed on the phase shifter 20, a calibration process is involved. Specifically, in one embodiment, the box cover 112 is provided with an elastic arm 112c, the elastic arm 112c is provided with a hook 1121c, and the power input rack 131 is provided with a groove 131b. The hook 1121c is detachably engaged with the groove 131b.

[0085] During calibration, the power input rack 131 is manually moved until the hook 1121c of the elastic arm 112c engages with the groove 131b, thereby returning the power input rack 131 to zero. During operation, when the transmission rod 133 drives the power input rack 131 to move, the hook 1121c disengages from the groove 131b, thereby preventing interference with the normal reciprocating movement of the power input rack 131.

[0086] Please continue reading Figure 8 , Figure 9 and Figure 11Furthermore, the calibration of the phase shifter 20 is also involved. Specifically, the housing 111 is provided with a positioning pin 111g, which is designed to detachably engage with the positioning notch 24 of the phase shifting medium. Therefore, by moving the phase shifting medium so that the positioning pin 111g is aligned and inserted into the positioning notch 24, the phase shifting medium can be calibrated to zero.

[0087] Please continue reading Figure 11 When the phase-shifting transmission device 10 is mounted on the phase shifter 20, in one embodiment, a carrier plate 111h is protruded from the outer wall of the box body 111, and the carrier plate 111h is provided with a mounting through hole 1111h, and a positioning pin 1112h is also provided on the carrier plate 111h.

[0088] The phase shifter 20 has a phase shifter housing 21 with a window formed therein. The window connects the medium of the phase shifter 20 inside with the external environment. The phase shift transmission device 10 is installed aligned with the window so that the gear mechanism is in transmission connection with the medium of the phase shifter 20 .

[0089] In addition, the phase shifter housing 21 is provided with a threaded hole aligned with the mounting through-hole 1111h, and a positioning socket aligned with the positioning pin 1112h. During installation, the positioning pin 1112h is first aligned and inserted into the positioning socket to complete the pre-positioning of the phase shift transmission device 10. Then, a threaded component such as a bolt is passed through the mounting through-hole 1111h and screwed into the threaded hole to lock and fix the phase shift transmission device 10 to the phase shifter 20. The installation method is simple, the connection strength is high, and it is convenient to assemble and disassemble.

[0090] It is understandable that in other optional embodiments, the phase-shifting transmission device 10 and the phase shifter 20 may also be assembled and fixed by at least one of snap connection, bonding, magnetic connection, welding, etc., which can be flexibly selected according to actual needs.

[0091] Please continue reading Figure 1 In addition to the above, the present application further proposes an antenna 100, comprising a phase shifter 20, the phase shifter 20 comprising a phase shifter housing 21, wherein a movable phase shifting medium is disposed inside the phase shifter housing 21; and a phase shifting transmission device 10 as described in any of the above embodiments, wherein the phase shifting transmission device 10 is stacked on the phase shifter housing 21 along a height direction of the phase shifter 20, and the phase shifting transmission device 10 is transmission-connected to the phase shifting medium.

[0092] The phase-shifting transmission device 10 is assembled and matched with the phase shifter 20 to transmit power to the phase-shifting medium inside the phase shifter 20, thereby driving the phase-shifting medium to move and achieve phase adjustment. Specifically, during use, the transmission case 11 is installed and stacked in the height direction of the phase shifter 20, and the power input mechanism 13 is connected to the power output mechanism of the phase shifter 20. The power output mechanism outputs driving force to the power input mechanism 13, which in turn drives the transmission mechanism 12 to move. Ultimately, the transmission mechanism 12 drives the phase-shifting medium inside the phase shifter 20 to move, thereby achieving phase adjustment. Compared to the prior art, the phase-shifting transmission device 10 of this solution is integrally stacked and installed in the height direction of the phase shifter 20, thereby effectively saving layout space in the length direction of the phase shifter 20, reducing the layout difficulty inside the antenna 100, and further facilitating a miniaturized design of the antenna 100.

[0093] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
