Description

Technical Field

[0001] The present invention relates to the technical field of antennas, and particularly relates to a pluggable driving device and an antenna transmission assembly. Background Art

[0002] With the continuous increase in the number of mobile communication terminal users, it is often required that a single antenna has a larger number of communication frequency bands, and the electrical downtilt angle of each communication frequency band needs to be independently controlled. To save the number of motors, the communication industry has successively developed a two-band multi-drive mechanism, and an RCU device is used to drive the two-band multi-drive mechanism. However, there are currently the following problems with the gear position display of the two-band multi-drive mechanism in the industry:

[0003] 1. Most two-band multi-drive mechanisms do not have a gear shift information display function in their structures, which will inevitably cause operators to be unable to intuitively distinguish the real-time gear position of the two-band multi-drive mechanism. Therefore, when the antenna needs to be debugged or repaired, it is impossible to quickly determine the actual position of the gear of the two-band multi-drive mechanism, and it can only be determined by reading information through devices such as a computer or a handheld device after the RCU is powered on. This method greatly affects work efficiency.

[0004] 2. For some types of two-band multi-drive mechanisms, even if a scale with gear position information is installed on their gear shift parts to achieve the gear position display function, although this method solves the gear position display problem of the two-band multi-drive mechanism, it will inevitably make the structure of the two-band multi-drive mechanism more complex and occupy a large amount of space inside the antenna and the end cover. Summary of the Invention

[0005] The purpose of the present invention is to solve at least one of the above problems. To achieve the purpose of the present invention, the following technical solutions are adopted:

[0006] In a first aspect, the present invention provides a pluggable driving device, including:

[0007] A driving device body, a shift driving assembly located inside the driving device body, and a gear position information display assembly;

[0008] Wherein, the shift driving assembly is used to output a first driving force to the outside of the driving device and drive the gear position information display assembly to switch to display the currently selected gear position information when outputting the first driving force.

[0009] Further improvement lies in that it further includes an adjustment driving assembly located inside the driving device body, and the adjustment driving assembly is used to output a second driving force to the outside of the driving device.

[0010] A further improvement is that the gear information display component includes a gear display gear that is transmission-connected to the gear shift drive component, and a plurality of antenna communication frequency band IDs representing different gears are printed on the front end face of the gear display gear around the center point of the front end face, and when the gear display gear rotates, the antenna communication frequency band ID corresponding to the currently selected gear is driven to rotate to a preset position for display.

[0011] A further improvement is that the driving device body includes a front cover assembly, a cavity, and a rear cover assembly, and the gear shift driving assembly and the gear position information display assembly are located in the cavity.

[0012] A further improvement is that the gear position display gear is rotatably mounted between the front end cover assembly and the rear end cover assembly.

[0013] A further improvement is that the rear end shaft of the gear display gear is installed in the circular hole of the rear end cover assembly, the front end hole of the gear display gear is installed in the circular axis of the front end cover assembly, and the gear display gear can rotate along the circular hole and the circular axis.

[0014] A further improvement is that a starting stop surface and a stop surface are provided on the gear display gear, and the starting stop surface and the stop surface can collide with the starting calibration surface and the stop calibration surface on the driving device body respectively, and the maximum rotation angle of the gear display gear is from the collision between the starting stop surface and the starting calibration surface to the collision between the stop surface and the stop calibration surface.

[0015] A further improvement is that the collision between the initial blocking surface and the initial comparison surface is the starting point of the gear shift stroke, and the collision between the initial comparison surface and the stop comparison surface is the ending point of the gear shift stroke.

[0016] A further improvement is that a gear position display window is provided on the front end cover assembly corresponding to the preset position.

[0017] In a second aspect, the present invention proposes an antenna transmission assembly, which includes a two-belt multi-transmission mechanism and a pluggable drive device as described in any one of the first aspects, wherein the pluggable drive device is detachably connected to the two-belt multi-transmission mechanism, and the pluggable drive device is used to output a first driving force and a second driving force to the two-belt multi-transmission mechanism.

[0018] Beneficial effects of the present invention:

[0019] The present invention can not only display the real-time gear position of the two-belt multi-transmission mechanism, but also avoid adding related shifting structures to the two-belt multi-transmission mechanism, thereby causing the structure of the two-belt multi-transmission mechanism to be complicated and occupy a large space. The present invention directly sets the shifting display in the pluggable drive device, which has the advantages of small space occupancy, simple structure and high versatility.

[0029] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by those skilled in the technical field to which this invention belongs. The terms used in the description of this invention in this article are only for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0030] The "first" and "second" involved in this invention do not represent specific quantities and sequences, but are only used for name distinction.

[0031] Please refer to the attached Figure 1 、attached Figure 2 、attached Figure 3 、attached Figure 4 、attached Figure 5 , a first aspect of an embodiment of the present invention provides a pluggable driving device, and the pluggable driving device includes:

[0032] A driving device body, a shift driving component and a gear position information display component located in the driving device body. Among them, the shift driving component is used to output a first driving force to the outside of the driving device and drive the gear position information display component to switch to display the currently selected gear position information when outputting the first driving force.

[0033] Specifically, the pluggable driving device further includes an adjustment driving component located in the driving device body, and the adjustment driving component is used to output a second driving force to the outside of the driving device.

[0034] It should be noted that the first driving force is used to drive an external two-belt multi-drive mechanism (not shown) to perform gear position switching selection, and the second driving force is used to drive an external two-belt multi-drive mechanism (not shown) to perform adjustment.

[0035] In this embodiment, the gear position information display component includes a gear position display gear 6 that is in transmission connection with the shift driving component. As Figure 4 shown, on the front end face 602 of the gear position display gear 6, a plurality of antenna communication frequency band IDs representing different gear positions are printed around the center point of the front end face 602. The plurality of antenna communication frequency band IDs are distributed in a circular pattern. When the gear position display gear 6 rotates, it drives the antenna communication frequency band ID corresponding to the currently selected gear position to rotate to a preset position for display.

[0036] In this embodiment, the driving device body includes a front end cover component 1, a cavity 2, and a rear end cover component 8. The shift driving component and the gear position information display component are located inside the cavity 2.

[0037] Specifically, as Figure 1 and Figure 2 shown, in this embodiment, the shift driving component includes a shift motor 3, an output gear 5, and a motor fixing plate 7. The adjustment driving component includes a travel motor 4 and a motor fixing plate 7. The shift motor 3 and the travel motor 4 are fixed on the motor fixing plate 7. The output gear 5 is installed on the rotating shaft 301 of the shift motor 3. The rotating shaft 301 can drive the output gear 5 to rotate synchronously. And the gear of the gear position display gear 6 meshes with the output gear 5. The rotation of the output gear 5 can drive the rotation of the gear position display gear 6.

[0038] It should be noted that those skilled in the art can also adjust the transmission ratio between the output gear 5 and the gear position display gear 6 according to actual needs or by other means (such as: adding a gear set gearbox), so as to meet the different shift strokes of different two-drive multi-drive mechanisms (not shown).

[0039] Preferably, the motor fixing plate 7 can be fixed to the rear end cover component 8 through fasteners.

[0040] Specifically, the shift motor 3, the travel motor 4, the output gear 5, the gear position display gear 6, and the motor fixing plate 7 are all placed inside the cavity 2. The front end cover component 1 and the rear end cover component 8 are respectively installed at the front and rear ends of the cavity 2, so as to assemble a pluggable driving device.

[0041] Specifically, in this embodiment, the gear position display gear 6 is rotatably installed between the front end cover component 1 and the rear end cover component 8. The rear end shaft 603 of the gear position display gear 6 is installed in the round hole 801 of the rear end cover component 8. The front end hole 601 of the gear position display gear 6 is installed in the round shaft 101 of the front end cover component 1. The gear position display gear 6 can rotate along the round hole 801 and the round shaft 101.

[0042] Specifically, as Figure 3As shown, in this embodiment, a starting stop surface 605 and an ending stop surface 604 are provided on the gear position display gear 6. The starting stop surface 605 and the ending stop surface 604 are located on one side of the front end surface 602 of the gear position display gear 6. The starting stop surface 605 and the ending stop surface 604 can respectively collide with the starting calibration surface 102 and the ending calibration surface 103 on the driving device body. The starting calibration surface 102 and the ending calibration surface 103 are located on the front end cover assembly 1. The maximum rotation angle of the gear position display gear 6 is from the start of the collision between the starting stop surface 605 and the starting calibration surface 102 to the end of the collision between the ending stop surface 604 and the ending calibration surface 103. This angle should correspond to the number of turns required for the shifting motor 3 to complete the shifting process.

[0043] Furthermore, to achieve a one-to-one correspondence between the two-belt multi-drive mechanism (not shown) and the gear position display of this pluggable drive device, it should be set that when the starting stop surface 605 collides with the starting calibration surface 102, it is the starting point of the shifting stroke of the two-belt multi-drive mechanism (not shown); when the starting calibration surface 102 collides with the ending calibration surface 103, it is the ending point of the shifting stroke of the two-belt multi-drive mechanism (not shown).

[0044] Specifically, as Figure 5 shown, in this embodiment, a gear position display window 104 is provided on the front end cover assembly 1 at the corresponding preset position. The display window 104 can only display the antenna communication frequency band ID corresponding to the currently selected gear position.

[0045] When the shifting motor 3 rotates to drive the synchronous rotation of the output gear 5, it also drives the rotation of the gear position display gear 6 meshing with the output gear 5. Different antenna communication frequency band IDs can be sequentially displayed at the display window 104 of the front end cover assembly 1. By observing the antenna communication frequency band ID, it is possible to know the real-time gear position of the current two-belt multi-drive mechanism (not shown).

[0046] The present invention can not only display the real-time gear position of the two-belt multi-drive mechanism (not shown), but also avoid adding relevant shifting structures on the two-belt multi-drive mechanism (not shown), thus causing problems such as the complexity of the structure of the two-belt multi-drive mechanism (not shown) and large space occupation. In this embodiment, the display of shifting is directly set inside the pluggable drive device, which has the advantages of small space occupation, simple structure, and high versatility.

[0047] In the second aspect of this embodiment, an antenna drive assembly is proposed. The antenna drive assembly includes a two-belt multi-drive mechanism and a pluggable drive device as described in any one of the first aspect. The pluggable drive device is detachably connected to the two-belt multi-drive mechanism, and the pluggable drive device is used to output a first driving force and a second driving force to the two-belt multi-drive mechanism.

[0048] Among them, the two-driving-multiple transmission mechanism refers to driving the antenna transmission component to select positions and adjust with two input powers. Since the two-driving-multiple transmission mechanism and other parts of the structure of the antenna transmission component are all well-known common knowledge in the art, they will not be described in detail in this embodiment. Those skilled in the art can also specifically refer to the content disclosed in the patent application with the application number CN202111271908.2 and the name "An Antenna Driving Device".

[0049] The pluggable driving device can be plugged and unplugged during use. The pluggable driving device itself is small in size and relatively quick and simple to assemble. When a fault occurs, it can be easily removed for repair or overall replacement without disassembling the antenna itself, which is convenient and fast.

[0050] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0051] The above-described embodiments only express the specific implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
