Description

Technical Field

[0001] The present disclosure relates to the field of communications, and more specifically to a transmission device for indicating a downtilt angle of an antenna, and an antenna having the transmission device. Background Art

[0002] In recent years, with the development of information and communication technologies such as mobile Internet and the Internet of Things, data traffic has continued to grow explosively, and the requirements for the signal receiving and transmitting performance of base station antennas have become increasingly higher. With the development of mobile communication technology, 5G systems have become increasingly popular, and the proportion of 5G base stations has also increased. However, whether it is a newly deployed 5G base station antenna or an existing 3G and 4G base station antenna, the downtilt angle of the base station antenna is related to key site operation indicators such as networking efficiency, signal coverage area and communication quality.

[0003] Different from the method of changing the antenna downtilt angle by directly adjusting the mechanical tilt angle of the mounting bracket at the communication site or communication tower, the method of changing the antenna beam by remotely adjusting the phase of the phase shifter reduces labor costs and the impact on electrical parameters, meets the operating conditions and improves work efficiency.

[0004] The use of a downtilt angle adjustment display device connected to the internal transmission device of the integrated antenna can clearly and intuitively indicate the specific value of the electrical downtilt angle inside the antenna, reduce the length of the package, and avoid problems such as the conventional indicating device being easily damaged or stuck under the influence of different working conditions, and being unfavorable to the waterproofing of the entire antenna.

[0005] CN106159441A discloses a schematic diagram of an angle indicator. In this patent application, reference numeral 11 is a housing with a window, reference numeral 14 is an external traction mechanism interface, and reference numeral 19 is a spring reset element. The angle display device utilizes an external traction force to overcome the retraction force of the reset element, and relies on various matching parts to make the angle disk and other components produce relative rotation to display the angle. Such a structural arrangement places relatively stringent requirements on the traction force of the antenna motor, and when the electrical inclination angle of the antenna is at a non-preset angle of the indicator, the internal structure of the antenna connected to the traction mechanism is in a stress state for a long time, which is not conducive to the stability of the electrical performance. In addition, the reliability of the torsion spring-type retraction element in coping with persistent stretching and severe temperature conditions is questionable.

[0006] Furthermore, patent application CN206163713U discloses a base station antenna and an electrical downtilt angle display device thereof. Figure 2The utility model has an indicator mark printed on the outside or inside of the lower end cover of the base station antenna, and a pointer is placed outside or inside the antenna housing. In order to adapt to different phase shifter strokes, the driven gear set or reduction box may be oversized or need to be redesigned. When the pointer is placed outside, the reliability of the rotation under different climatic conditions is insufficient. When the pointer is placed inside, the internal assembly display effect is poor. Summary of the invention

[0007] In order to solve the technical problems existing in the prior art, namely, the downtilt angle indicator device has too strict requirements on traction force and its versatility is poor, the inventors of the present disclosure innovatively conceived of using the combination of push-pull parts and rotating parts to convert linear motion into rotational motion, thereby being able to adapt to most antennas and making the display of the downtilt angle more convenient and flexible. In order to achieve the above-mentioned technical effects, the first aspect of the present disclosure proposes a transmission device for indicating the downtilt angle of an antenna, the transmission device comprising: a fixed cavity, the fixed cavity having a accommodating cavity, the inner wall of the accommodating cavity having a first guide member extending along the longitudinal axis of the fixed cavity; a push-pull member, the push-pull member being accommodated in the accommodating cavity, and the push-pull member having a second guide member that matches the shape of the first guide member, so that the push-pull member can move relative to the fixed cavity along the longitudinal axis of the fixed cavity, wherein a third guide member is also provided on the circumferential surface of the push-pull member, and the third guide member is spirally provided on the circumferential surface of the push-pull member; and a rotating member, the rotating member being provided with a fourth guide member, and the fourth guide member matches the shape of the third guide member, so that the rotating member can rotate around the longitudinal axis when the push-pull member moves linearly along the longitudinal axis.

[0031] As mentioned above, the prior art has the following technical problems, namely, the downtilt angle indicator device has too stringent requirements on traction force and its versatility is poor. The inventor of the present disclosure innovatively conceives of using a push-pull member and a rotating member to convert linear motion into rotational motion, thereby being able to adapt to most antennas and making the display of the downtilt angle more convenient and flexible. In summary, in order to achieve the above technical effects, the first aspect of the present disclosure proposes a transmission device for indicating the downtilt angle of an antenna, the transmission device comprising: a fixed cavity, the fixed cavity having a receiving cavity, the inner wall of the receiving cavity having a first guide extending along the longitudinal axis of the fixed cavity; a push-pull member, the push-pull member being received in the receiving cavity, and the push-pull member having a second guide matching the shape of the first guide, so that the push-pull member can move relative to the fixed cavity along the longitudinal axis of the fixed cavity, wherein a third guide is also provided on the circumferential surface of the push-pull member, the third guide being spirally provided on the circumferential surface of the push-pull member; and a rotating member, the rotating member having a fourth guide matching the shape of the third guide, so that the rotating member can rotate around the longitudinal axis when the push-pull member moves linearly along the longitudinal axis.

When the push-pull member moves linearly, the third guide member and the fourth guide member cooperate to enable the rotating member to rotate around the longitudinal axis when the push-pull member moves linearly along the longitudinal axis, thereby accurately displaying the downtilt angle of the antenna. Moreover, the transmission device for indicating the downtilt angle of the antenna proposed in the present disclosure has good versatility and can adapt to most application scenarios of displaying the downtilt angle of the antenna.

[0032] The following will be combined with the attached Figure 1 To Attachment Figure 7 To describe the transmission device proposed according to the present disclosure. Figure 1 FIG. 1 is a schematic diagram showing a transmission device according to an embodiment of the present disclosure, Figure 2 FIG. 1 shows a schematic diagram of the connection of the driving member of the transmission device according to an embodiment of the present disclosure. Figure 3 A schematic diagram of a fixed cavity of a transmission device according to an embodiment of the present disclosure is shown.

[0034] from Figure 1 It can be seen that the transmission device for indicating the downtilt angle of the antenna proposed in the present disclosure includes: a fixed cavity 11, the fixed cavity 11 has a receiving cavity, and the inner wall of the receiving cavity has a first guide member 111 ( Figure 1 Not shown, it will be Figure 3 The push-pull member 12 is accommodated in the accommodating cavity of the fixed cavity 11, and the push-pull member 12 has a second guide member 121 (which matches the shape of the first guide member 111) Figure 1 Not shown, it will be Figure 4 The push-pull member 12 is configured to be described as a protruding strip, so that the push-pull member 12 can move relative to the fixed cavity 11 along the longitudinal axis of the fixed cavity 11, wherein a third guide member 123 ( Figure 1 Not shown, it will be Figure 4 The third guide member 123 is spirally arranged on the circumferential surface of the push-pull member 12; and the rotating member 13 is provided with a fourth guide member 132 ( Figure 1 Not shown, it will be Figure 5 The fourth guide member 132 is matched with the third guide member 123 in shape so that the rotating member 13 can rotate around the longitudinal axis when the push-pull member 12 moves linearly along the longitudinal axis. The transmission device disclosed in the present disclosure solves the problems of poor indication accuracy, complex structure and poor display effect of the existing downtilt angle display and adjustment device during use, and also solves the problem that the downtilt angle display and adjustment device has poor adaptability to phase shifters of different strokes and types and the structure cannot be flexibly adjusted. Figure 1In the illustrated embodiment, the first guide member 111 is implemented as a groove, and correspondingly the second guide member 121 is implemented as a protrusion. However, those skilled in the art should understand that as long as the matching and limiting can be achieved, that is, one of the first guide member and the second guide member is constructed as one of the protrusion and the groove, and the other of the first guide member and the second guide member is constructed as the other of the protrusion and the groove. Those skilled in the art should understand that the two arrangements disclosed herein, that is, one of the first guide member and the second guide member is constructed as one of the protrusion and the groove, and the other of the first guide member and the second guide member is constructed as the other of the protrusion and the groove, are both feasible, as long as the push-pull member can be able to perform linear motion relative to the fixed cavity, thereby making necessary preparations for the downward tilt angle of the display antenna, these technical solutions will fall within the scope of protection of the present disclosure. That is to say, the transmission device may also include a driving member ( Figure 1 Not shown, it will be Figure 2 It is described, for example, it is implemented as a push-pull rod 15, and the driving member 15 is fixedly connected to the push-pull member 12 via the notch structure 112 on the cavity wall of the fixed cavity 11. In this way, the driving member 15 can be connected to the driving motor, for example, and it is fixedly connected to the push-pull member 12 via the notch structure 112 provided on the cavity wall of the fixed cavity 11, so that the movement of the driving motor will not interfere with the fixed cavity 11, that is, the fixed cavity 11 will not affect the movement of the driving member 15 because the notch structure 112 is provided thereon, so that the driving member 15 can drive the push-pull member 12 to move, and finally can drive the rotating member to move to display the downtilt angle of the antenna. For example, a connecting structure 151 can be separately provided between the driving member 15 and the push-pull member 12. Of course, the connecting structure 151 can also be integrally formed with the driving member 15 or integrally formed with the push-pull member 12, for example.

[0035] More specifically, if Figure 1The figure shows a front view of a base station antenna angle display adjustment device, and the transmission device shown in the figure is composed of a fixed cavity 11, a push-pull member 12, an internal rotating member 13 and a cover plate 14. The fixed cavity 11 is provided with a plurality of closed or semi-closed accommodating chambers, wherein the first accommodating chamber can accommodate the push-pull member 12 and the internal rotating member 13 and other parts. The first accommodating chamber of the fixed cavity 11 can be provided with a feature 111 (such as the guide groove shown in the figure), which cooperates with the feature 121 (such as the guide strip) on the push-pull member 12, so as to realize the functions of the fixed cavity 11 to maintain the movement direction of the accommodated parts, protect the accommodated parts from being affected, and enhance the reliability of the assembly matching. The power of the driving device 15 (for example, implemented as the driving member 15) is connected to the push-pull member 12 in the transmission device via the feature 151 optionally provided on itself, and the power is input into the display adjustment device of the antenna downtilt angle. This feature 151 can also be provided as a separate adapter to realize the input of power. Under different use conditions, a notch feature 112 can be provided on the fixed cavity 11 to achieve functions such as accommodating the adapter 151 and maintaining the direction of movement. A push arm feature 122 is provided on the push-pull member 12, and a reverse push arm structure 131 is provided on the internal rotating member 13. Under the action of input power, the push-pull member 12 will make a linear motion. When it reaches a preset stroke, the push arm feature 122 on the push-pull member 12 will cooperate with the reverse push arm structure 131 of the internal rotating member to make the internal rotating member 13 rotate. At the same time, a guide groove feature 123 can be provided on the push-pull member 12 to cooperate with the convex feature 132 provided on the internal rotating member 13. Under the joint action of the input power and the two matching features, the function of the push-pull member 12 driving the internal rotating member 13 to rotate can be generated.

[0036] In addition, the internal rotating member 13 is provided with a fixing feature 133, and the fixing feature 133 can cooperate with the feature 213 of the second accommodating chamber provided in the fixed cavity 11, so that the linear motion tendency of the internal rotating member 13 is suppressed. Similarly, the feature 133 of the internal rotating member 13 and the feature 213 on the fixed cavity 11 may no longer be provided with corresponding connection features, but preferably, a cover plate 14 is provided, and then the cover plate 14 is matched with the fixed cavity 11, so as to enhance the overall sealing of the transmission device and suppress the linear motion tendency of the internal rotating member 13.

[0037] Furthermore, the internal rotating member 13 may be provided with a feature 134 that can realize the accommodation and fixing function, the fixed cavity 11 or the cover plate may be provided with a corresponding feature 113 that realizes the accommodation and fixing function, and the accommodating chamber in the fixed cavity 11 may be provided with and accommodate a rotating member 16, which may be implemented as a torsion spring, and one end of the rotating member 16 cooperates with the feature provided in the fixed cavity or the cover plate, and the other end cooperates with the feature 134. The rotating member 16 can make the internal rotating member 13 generate a rotation tendency opposite to the movement direction driven by the push-pull member 12.

[0038] from Figure 1It can be seen from the structural schematic diagram of the transmission device shown therein that the transmission device disclosed in accordance with the content of the present disclosure can adopt a closed or semi-closed design, and the transmission device is provided with auxiliary features for matching assembly. The internal body of the transmission device is composed of a fixed cavity 11, a push-pull member 12 implemented as an internal push rod, and a rotating member 13 implemented as an internal rotating member. The fixed cavity 11 and its design features can accommodate the internal push rod and the internal rotating member. A matching design is adopted between the internal push rod and the internal rotating member. The power is introduced into the internal push rod of the transmission device through the input end. The internal push rod that performs linear motion in the transmission device uses two push arms 122 to push the reverse push arm 131 provided on the internal rotating member, so that the internal rotating member generates a rotational motion in the fixed cavity 11, and then the display of the angle adjustment value of the transmission device is realized. The internal push rod can also be provided with a groove feature 123 for accommodating the convex feature 132 on the internal rotating member. The groove feature 123 cooperates with the convex feature 132 on the internal rotating member to produce the function of the internal push rod driving the rotating member. One end of the fixed cavity 11 is provided with a cavity for accommodating the internal rotating member feature and the rotating member 16. The rotating member 16 can make the internal rotating member produce a rotation trend opposite to the movement direction driven by the internal push member. A cover plate 14 can be provided to connect with the fixed cavity 11 to increase the closedness of the angle indicating device. In summary, one of the third guide member and the fourth guide member is constructed as one of a protrusion and a groove, and the other of the third guide member and the fourth guide member is constructed as the other of a protrusion and a groove. Those skilled in the art should understand that the two arrangements disclosed herein, i.e., one of the third guide member and the fourth guide member is constructed as one of a protrusion and a groove, and the other of the third guide member and the fourth guide member is constructed as the other of a protrusion and a groove, are both feasible, as long as the linear motion of the push-pull member can drive the rotation of the rotating member, thereby being able to display the downward tilt angle of the antenna, these technical solutions will fall within the protection scope of the present disclosure. A push arm structure is provided on one of the push-pull member and the rotating member, and a reverse push arm structure is provided on the other of the push-pull member and the rotating member. In this way, the contact and transmission between the push-pull member and the rotating member can be stabilized, thereby helping to improve the working stability of the transmission device according to the present disclosure.

[0039] Furthermore, if Figure 7 As shown, the cover plate 14 can be provided with a schematic scale, which can be attached to the fixed cavity, internal rotating parts, cover plates or antenna end covers and other loose parts by means including but not limited to stickers, silk screen printing and spray painting, and the angular range of the schematic scale used in the circumferential direction can be quickly adapted according to the stroke, power input configuration and internal design of the device. Figure 7In the embodiment shown, the scale is marked with numbers 2, 4, 6, 8, 10 and 12, which can also be implemented as other values, such as 3°, 6°, 9°, 12°, 15°, 18°. The specific schematic scale marking can be customized according to the needs of the user.

[0040] In the embodiment shown in the accompanying drawings, the rotating member 13 is sleeved in the cavity formed by the push-pull member 12. However, those skilled in the art should understand that other arrangements may also be adopted, such as the push-pull member 12 being sleeved in the cavity formed by the rotating member 13. Those skilled in the art should understand that the two arrangements disclosed herein, i.e., the push-pull member 12 being sleeved in the cavity formed by the rotating member 13 or the rotating member 13 being sleeved in the cavity formed by the push-pull member 12, are both feasible, as long as the linear motion of the push-pull member 12 can drive the rotation of the rotating member 13, thereby being able to display the downtilt angle of the antenna, these technical solutions will fall within the protection scope of the present disclosure.

[0041] Each component in the transmission device proposed according to the present disclosure is designed to be easy to mold and easy to assemble, while taking into account both working reliability and manufacturing economy. The combined design of the inner push arm and the push groove of the transmission device proposed according to the present disclosure ensures the design accuracy of the overall mechanism, and the design of the fixed cavity, internal rotating parts and cover plates ensures the display effect of the overall mechanism. When the transmission device proposed according to the present disclosure is not connected to the power input, the indication value of the transmission device body is easy to fix and adjust. The driving force required by the transmission device proposed according to the present disclosure is small and will not affect the performance of the existing antenna system.

[0042] The schematic scale can be attached to the fixed cavity, the internal rotating part, the cover plate or the antenna end cover and other loose parts by means including but not limited to stickers, silk screen printing and spray painting, and the angle range used in the circumferential direction of the schematic scale can be quickly adapted according to the stroke, the power input end configuration and the internal design of the device. In summary, the scale mark or the indicator mark is formed by pasting, silk screen printing or spray painting. As a result, the schematic scale can select schemes according to different usage scenarios, and the adaptability to phase shifters of different strokes and types is greatly improved, and the structure is relatively simple and flexible to adjust. The schematic scale can be attached to the fixed cavity, the internal rotating part, the cover plate or the antenna end cover and other loose parts by means including but not limited to stickers, silk screen printing and spray painting, and the angle range 141 used in the circumferential direction of the schematic scale can be quickly adapted according to the stroke, the power input end configuration and the internal design of the device. In summary, in the technical solution according to the content of the present disclosure, the transmission device also includes an indicator mark arranged at the end of the rotating part. In this way, after the rotating member rotates, the position of the indicator mark thereon changes accordingly, so that the user can conveniently observe the position of the indicator mark and thus determine the size of the downtilt angle of the antenna.

[0043] In the technical solution according to the present disclosure, the transmission device further includes an end cap, which is fixedly connected to the fixed cavity and has a circumferential scale mark on its surface. In this way, after the rotating member rotates, the position of the indicator mark on it changes accordingly, so that the user can conveniently observe the position of the indicator mark with the help of the circumferential scale mark to determine the downtilt angle of the antenna.

[0044] In the technical solution according to the present disclosure, the transmission device also includes a torsion spring arranged between the rotating member and the fixed cavity. In this way, the transmission device according to the present disclosure can have a reaction force opposite to the drive of the push-pull member, so that the transmission device according to the present disclosure can display the downward inclination angle more accurately. In the technical solution according to the present disclosure, the transmission device also includes a stopper arranged at the end of the rotating member, and the stopper is fixedly connected to the fixed cavity. In this way, the rotating member will not move linearly with the push-pull member, but will rotate, so that the transmission efficiency of the transmission device according to the present disclosure is higher.

[0045] In addition, the second aspect of the present disclosure further discloses an antenna, which includes the transmission device according to the first aspect of the present disclosure.

[0046] In summary, in the transmission device and the corresponding antenna according to the contents of the present disclosure, the push-pull member can make a linear motion relative to the fixed cavity by means of the cooperation of the first guide member and the second guide member. When the push-pull member makes a linear motion, the third guide member and the fourth guide member cooperate to make the rotating member rotate around the longitudinal axis when the push-pull member moves linearly along the longitudinal axis, thereby making it possible to accurately display the downtilt angle of the antenna. Moreover, the transmission device for indicating the downtilt angle of the antenna proposed according to the contents of the present disclosure has good versatility and can adapt to most application scenarios of the downtilt angle display of the antenna.

[0047] The above is only an optional embodiment of the embodiment of the present disclosure, and is not intended to limit the embodiment of the present disclosure.
