Description

Technical Field

[0001] This invention relates to the field of communication module technology, specifically to a 5G communication module with enhanced antenna signal and its usage method. Background Technology

[0002] A communication module is an integrated hardware component, typically including a baseband chip, radio frequency circuit, memory, and standard interface. It is the core module for realizing the wireless communication function of a device. It can convert the data generated by the device into standard wireless signals that conform to a specific network for transmission and reception. Through the built-in communication protocol stack, the module simplifies the complexity of device networking, enabling terminal devices to easily access cellular networks or local area networks and realize remote data transmission, control, and interconnection.

[0003] Based on the traditional communication module architecture, the 5G communication module integrates a dedicated 5G baseband chip, a high-performance radio frequency front-end, a multi-mode communication protocol stack, and a high-speed interface. It supports dual-mode operation of SA (Standalone) and NSA (Non-Standalone) networks and can simultaneously meet the technical requirements of three major 5G application scenarios: enhanced mobile broadband, ultra-reliable and ultra-low latency communication, and massive machine-type communication. It has the significant characteristics of high speed, low latency, and wide connectivity.

[0004] 5G communication modules are typically paired with high-performance antennas to support multi-band signal transmission and reception, such as millimeter wave and Sub-6GHz. Through the coordinated work of the module and antenna, the stability and coverage of signal transmission can be effectively improved, ensuring that 5G terminals can still achieve high-speed data transmission and low-latency command interaction in complex electromagnetic environments.

[0005] However, to ensure stable operation of antennas in complex environments, their exterior is usually sealed to isolate moisture, dust, and other external intrusions. While this effectively isolates the harsh external environment from corroding the internal components of the antenna, it also significantly hinders the conduction and dissipation of heat generated during antenna operation. As 5G modules continue to transmit and receive high-frequency, high-power signals, the heat accumulation inside the antenna intensifies, and the temperature rises rapidly, causing antenna performance degradation, such as impedance mismatch, gain reduction, and frequency drift. This results in signal transmission interruption, increased data packet loss rate, and in severe cases, even damage to RF front-end devices, directly affecting the reliability and lifespan of the communication module. Therefore, this paper proposes a 5G communication module with antenna signal enhancement and its usage method to address the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a 5G communication module with enhanced antenna signal and its usage method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A 5G communication module for enhancing antenna signals and its usage method are disclosed. The module includes a module substrate on which an antenna assembly is mounted. The antenna assembly includes a bent connector, a housing assembly fixedly connected to the upper end of the bent connector, an antenna body inserted into the bent connector, a rotating tube rotatably mounted on the outer side of the housing assembly, a locking block fixedly connected to the inner side of the rotating tube, an adjustment assembly fixedly connected to one side of the locking block, a rotating plate fixedly connected to the upper end of the adjustment assembly, a spring fixedly connected to the inner side of the upper end of the housing assembly, a cover fixedly connected to one end of the spring, an antenna housing including an antenna shell, a curved groove and a strip groove formed therein, and an adjustment assembly including a support rod, a short rod fixedly connected to the outer side of the support rod, a steel ring fixedly connected to one end of the short rod, a short shaft fixedly connected to the bottom end of the steel ring, an adjustable blade fixedly connected to the bottom end of the short shaft, a limiting shaft bonded to one side of the adjustable blade, and a limiting ring penetrating through the limiting shaft.

[0009] As a further optimization of the present invention, the card blocks are inserted and slidably disposed in the curved groove, and a portion of the card blocks are disposed inside the antenna housing. There are two card blocks, and the two card blocks are symmetrically distributed.

[0010] As a further optimization of the present invention, the rotating plate is engaged and rotated within the shell cover, and the projection shape of the rotating plate in the vertical direction is a fan shape, with the central angle of the fan shape being between 50° and 135°.

[0011] As a further optimization of the present invention, the strip groove is disposed below the curved groove, the projection of the strip groove in the vertical direction is an isosceles trapezoid, and the cross-sectional area of ​​the strip groove decreases sequentially from bottom to top.

[0012] As a further optimization of the present invention, the inner side of the rotating tube is attached to the outer side of the antenna housing, the projection of the antenna housing in the vertical direction is annular, and the lateral projection of the antenna housing is an isosceles trapezoid.

[0013] As a further optimization of the present invention, the antenna housing and the cover are coaxially arranged, the upper end face of the antenna housing and the bottom end face of the cover have the same shape, and the inner side of the cover is arc-shaped.

[0014] As a further optimization of the present invention, the position of the support rod corresponds one-to-one with the position of the locking block and is fixed by welding. A gap is provided between the outer side of the support rod and the inner side of the antenna housing. The antenna body is disposed between the two adjustment components.

[0015] As a further optimization of the present invention, the adjustable blades are provided in multiple ways, and the multiple adjustable blades are arranged in a ring array around the antenna body. The adjustable blades are arc-shaped, and a flow guide groove is opened on one side of the adjustable blade.

[0016] As a further optimization of the present invention, the central axis of the steel ring and the central axis of the limiting ring are on the same straight line, the limiting axis and the short axis are parallel to each other, and the outer side of the limiting ring is in contact with the inner side of the antenna housing.

[0017] A method for using a 5G communication module with enhanced antenna signal:

[0018] Step 1: Antenna assembly installation: First, power off the module base plate. After stabilizing the module base plate, pass the bent connector through the module base plate housing and screw it onto the module base plate body. Then, rotate the housing assembly to adjust the angle between the housing assembly and the bent connector. After confirming that the antenna assembly is installed and fixed, plug the module base plate into the power adapter, turn on the power, observe the indicator lights on the module base plate, and use a signal testing tool in the commonly used equipment area.

[0019] Step 2: Adjusting the heat dissipation of the antenna assembly: Rotate the rotating tube to make the rotating tube, the bent connector and the housing assembly rotate relative to each other. The rotation of the rotating tube causes the locking block to slide in the curved groove. As the locking block slides in the curved groove, the rotating tube and the antenna housing are axially displaced. The strip groove is exposed from below the rotating tube. When the air passes through the surface of the antenna housing, it enters the interior of the antenna housing through the strip groove. When the locking block slides in the curved groove, the support rod fixed to it pushes the rotating plate upward, causing the rotating plate to separate the housing cover from the antenna housing. At the same time, a part of the rotating plate is screwed into the housing cover, allowing the air to flow out from the housing cover.

[0020] Step 3: Adjustment of airflow speed inside the antenna assembly: The rotation of the support rod drives the short rod and the steel ring fixedly connected to the short rod to rotate. The rotation of the steel ring drives the short shaft and the adjustable blades connected to the short shaft to rotate. When the adjustable blades rotate, the limiting ring is stationary due to the friction force of the inner wall of the antenna shell. The adjustable blades only drive the limiting shaft in the limiting ring to rotate. Air enters the antenna shell through the strip groove, and after being guided by the adjustable blades, it flows out from the top of the antenna shell.

[0021] Step 4: Isolate the inside and outside of the antenna assembly: When the antenna assembly does not require heat dissipation or is not used for a long time, the rotating tube can be rotated so that the bottom end of the rotating tube fits with the top end of the bent connector. At the same time, the rotating tube covers the strip groove and the curved groove. The rotating tube drives the locking block to move, and the locking block drives the rotating plate to reset. The cover falls down and closes with the antenna shell, and the antenna assembly is in a sealed state.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this invention, the antenna assembly introduces an openable and closable heat dissipation mechanism. When the module is under high load or the ambient temperature is high, the user or system can easily rotate the antenna assembly to form an air outlet channel, thus quickly opening the heat dissipation channel. When the device is under low load, in bad weather, or not in use, the antenna assembly can be restored to its sealed state by rotating it in the opposite direction, restoring its protection level and effectively isolating external moisture and dust.

[0024] 2. In this invention, the housing assembly and adjustment assembly can actively guide and enhance the airflow field flowing into the antenna housing, effectively sort and accelerate the cold air entering the antenna housing, and guide the airflow to more concentratedly and efficiently flush the main heat source area.

[0025] 3. In this invention, by highly integrating components such as the housing assembly, antenna body, and adjustment assembly, the signal transmission and reception performance of the antenna itself is not interfered with, and indirect heat dissipation optimization can be achieved without additional external heat dissipation accessories, thus saving valuable internal space of the device to the greatest extent.

[0039] Please see Figures 1-8 The present invention provides a technical solution:

[0040] A 5G communication module for enhancing antenna signals and its usage method include a module substrate 1, an antenna assembly 2 mounted on the module substrate 1, the antenna assembly 2 including a bent connector 21, a housing assembly 22 fixedly connected to the upper end of the bent connector 21, an antenna body 23 inserted into the bent connector 21, a rotating tube 24 rotatably mounted on the outer side of the housing assembly 22, a locking block 25 fixedly connected to the inner side of the rotating tube 24, an adjusting assembly 26 fixedly connected to one side of the locking block 25, a rotating plate 27 fixedly connected to the upper end of the adjusting assembly 26, and a spring 28 fixedly connected to the inner side of the upper end of the housing assembly 22. One end of the 8 is fixedly connected to a cover 29. The housing assembly 22 includes an antenna housing 221. A curved groove 222 and a strip groove 223 are provided in the antenna housing 221. The adjustment assembly 26 includes a support rod 261. A short rod 262 is fixedly connected to the outside of the support rod 261. A steel ring 263 is fixedly connected to one end of the short rod 262. A short shaft 264 is fixedly connected to the bottom end of the steel ring 263. An adjustable blade 265 is fixedly connected to the bottom end of the short shaft 264. A limiting shaft 266 is bonded to one side of the adjustable blade 265. A limiting ring 267 is connected through the limiting shaft 266.

[0041] As a further implementation of this solution, the card block 25 is inserted and slidably disposed in the curved groove 222, and part of the card block 25 is disposed inside the antenna housing 221. There are two card blocks 25, which are symmetrically distributed. The symmetrical arrangement of the card blocks 25, combined with the shape of the curved groove 222, allows the components connected to it to move stably as they slide in the curved groove 222.

[0042] As a further implementation of this solution, the rotating plate 27 is engaged and rotated within the cover 29. The vertical projection of the rotating plate 27 is fan-shaped, with a central angle between 50° and 135°. The shape of the rotating plate 27 is designed so that a portion of it can be screwed into the cover 29, while ensuring that it will not fall out of the cover 29 when it rotates relative to the cover 29.

[0043] As a further implementation of this scheme, the strip groove 223 is set below the curved groove 222. The projection of the strip groove 223 in the vertical direction is an isosceles trapezoid, and the cross-sectional area of ​​the strip groove 223 decreases from bottom to top. The shape design of the strip groove 223 can form a constraining guiding effect on the vertically flowing air when air flows through it, forcing the airflow to converge orderly along the axial direction during the flow through the groove, and the flow velocity increases in a gradient.

[0044] As a further implementation of this scheme, the inner side of the rotating tube 24 is attached to the outer side of the antenna housing 221. The vertical projection of the antenna housing 221 is annular, and the horizontal projection of the antenna housing 221 is an isosceles trapezoid. The shape design of the antenna housing 221 allows the air entering it to flow out from bottom to top, which increases the flow velocity due to the reduction of the cross-sectional area, thereby quickly carrying away the heat accumulated inside the antenna housing 221.

[0045] As a further implementation of this solution, the antenna housing 221 and the cover 29 are coaxially arranged. The upper surface of the antenna housing 221 and the bottom surface of the cover 29 have the same shape. The inner side of the cover 29 is arc-shaped. The coaxial design between the antenna housing 221 and the cover 29 allows the cover 29 to be accurately placed on the upper part of the antenna housing 221. The arc-shaped design of the inner side of the cover 29 allows the impact of the air flowing out of the antenna housing 221 to be evenly distributed to its edges.

[0046] As a further implementation of this solution, the position of the support rod 261 corresponds one-to-one with the position of the locking block 25, and they are fixed by welding. There is a gap between the outer side of the support rod 261 and the inner side of the antenna housing 221. The antenna body 23 is set between the two adjustment components 26. The connection between the support rod 261 and the locking block 25 allows it to move with the movement of the locking block 25. Its design of not contacting the antenna housing 221 ensures that it will not be obstructed when moving with the locking block 25.

[0047] As a further implementation of this solution, multiple adjustable blades 265 are provided, arranged in a ring array around the antenna body 23. The adjustable blades 265 are arc-shaped, and a guide groove is provided on one side of each blade. The central axis of the steel ring 263 and the central axis of the limiting ring 267 are on the same straight line. The limiting axis 266 and the short axis 264 are parallel to each other. The outer side of the limiting ring 267 is in contact with the inner side of the antenna housing 221. When the steel ring 263 rotates, the limiting ring 267 will rotate relative to the antenna housing 221 due to the restriction of the limiting ring 267. At this time, the parallel limiting axis 266 and the short axis 264 will also be relatively displaced, causing the short axis 264 to drive the adjustable blades 265 to rotate around the limiting axis 266. The multiple adjustable blades 265 cooperate with each other, and combined with their own arc shape and the guide groove on one side, they can better adjust the tangential speed of the flowing air, thereby removing the heat accumulated inside the antenna housing 221 more quickly.

[0048] Workflow: First, power off module substrate 1 and stabilize it. Then, pass the bent connector 21 through the housing of module substrate 1 and screw it onto the main body of module substrate 1. Next, rotate housing assembly 22 to adjust the angle between housing assembly 22 and bent connector 21. After confirming that antenna assembly 2 is installed and fixed, plug the power adapter into module substrate 1, turn on the power, observe the indicator lights on module substrate 1, and in the commonly used equipment area, use a signal testing tool to rotate the rotating tube 24 to ensure proper connection between the rotating tube 24, bent connector 21, and housing assembly 22. As the rotating tube 24 rotates, it causes the locking block 25 to slide in the curved groove 222. With the sliding of the locking block 25 in the curved groove 222, an axial relative displacement occurs between the rotating tube 24 and the antenna housing 221. The strip groove 223 is exposed from below the rotating tube 24. When air passes over the surface of the antenna housing 221, it enters the interior of the antenna housing 221 through the strip groove 223. When the locking block 25 slides in the curved groove 222, the support rod 261 fixed to it pushes the rotating plate 27 upwards, causing the rotating plate 27 to separate the housing cover 29 from the antenna housing 221. Due to the spring 28, the housing cover 29... Since radial relative displacement between the antenna housing 221 and the cover 29 is difficult, the cover 29 moves up and down almost along the axis of the antenna housing 221 when it is raised. Simultaneously, a portion of the rotating plate 27 is screwed into the cover 29, allowing air to flow out from the cover 29. The rotation of the support rod 261 drives the short rod 262 and the steel ring 263 fixedly connected to the short rod 262 to rotate. The rotation of the steel ring 263 drives the short shaft 264 and the adjustable blade 265 connected to the short shaft 264 to rotate. When the adjustable blade 265 rotates, the limiting ring 267 remains stationary due to the frictional force of the inner wall of the antenna housing 221. Five limit rings 267 rotate the limit shaft 266 in the limit ring 267. Air enters the antenna housing 221 through the strip groove 223, is guided by the adjustable blade 265, and flows out from the upper end of the antenna housing 221. When the antenna assembly 2 does not need heat dissipation or is not used for a long time, the rotating tube 24 can be rotated so that the bottom end of the rotating tube 24 fits with the upper end of the bent connector 21. At the same time, the rotating tube 24 covers the strip groove 223 and the curved groove 222. The rotating tube 24 drives the locking block 25 to move, the locking block 25 drives the rotating plate 27 to reset, and the cover 29 falls down to close with the antenna housing 221, so that the antenna assembly 2 is in a sealed state.
