Description
Technical Field
[0001] This invention relates to a pluggable low-power 5G communication module and its usage method, particularly to a pluggable low-power 5G communication module and its usage method, belonging to the field of low-power 5G communication module installation technology. Background Technology
[0002] Plug-in 5G communication modules are increasingly used in mobile devices such as autonomous navigation vehicles. These modules are typically connected to the vehicle's adapter port via a physical connector to enable power supply and data transmission. In existing technologies, the connection between modules and vehicle interfaces often relies on simple mechanical clips or screws for fixing. The stability of this connection is easily affected by vibrations and impacts during vehicle operation, posing a risk of loosening. Furthermore, to ensure a tight connection, some designs employ additional locking mechanisms, but this makes the plugging and unplugging operation cumbersome and inconvenient when the module needs replacement or maintenance. In addition, the structural design of traditional modules does not adequately consider adaptability to changes in ambient temperature. Fluctuations in ambient temperature may cause thermal expansion and contraction of connecting components, affecting the stability of the connection interface and even compromising the seal. Based on the aforementioned existing technologies, current pluggable 5G communication modules mainly face the following technical problems: First, the connection method between the plug and the vehicle interface has poor vibration resistance and is prone to loosening under the complex operating conditions of mobile devices, affecting communication reliability; Second, the measures taken to ensure connection stability often contradict the ease of operation, making it difficult to balance "firm connection" and "easy plugging and unplugging"; Third, there is a lack of effective temperature compensation mechanisms. When the module operates in a wide temperature range environment, the negative pressure adsorption force or physical contact pressure of its connection parts may change, leading to a decrease in connection reliability. Therefore, it is urgent to improve a pluggable low-power 5G communication module and its usage method to solve the above-mentioned problems. Summary of the Invention
[0003] The purpose of this invention is to provide a pluggable low-power 5G communication module and its usage method to solve the following technical problems currently faced by pluggable 5G communication modules: First, the connection between the plug and the vehicle interface has poor vibration resistance and is prone to loosening under the complex operating conditions of mobile devices, affecting the reliability of communication; Second, the measures taken to ensure connection stability often contradict the convenience of operation, making it difficult to balance "firm connection" and "easy plugging and unplugging"; Third, there is a lack of effective temperature compensation mechanism. When the module works in a wide temperature range environment, the negative pressure adsorption force or physical contact pressure of its connection part may change, leading to a decrease in connection reliability.
[0004] To achieve the above objectives, the present invention provides the following technical solution: A pluggable low-power 5G communication module and its usage method are disclosed, comprising a sealing cover, a base, and a connector. The lower end of the sealing cover is fixedly connected to a base for mounting the 5G communication module motherboard via screws. A connector is mounted on one end of the base. Adsorption components are mounted at both ends on the side of the base where the connector is mounted. A negative pressure component is mounted on one side of the adsorption component. A sealing component is mounted on the upper end of the negative pressure component. An exhaust component is installed inside the sealing component. The adsorption component includes a fixing column, with a rubber gasket fixedly connected to the top of the fixing column. Connecting components are mounted on both sides of the fixing column, and a negative pressure compensation component is mounted on the outer side of the fixing column. The negative pressure compensation component includes a hollow column, which comprises a column body. The middle of the column body is filled with a thermally expanding material that expands upon heating and contracts upon cooling. A sealing plate is mounted on one side of the thermally expanding material. A transmission component is installed inside the hollow column. A vertical rod is fixedly connected to one end of the transmission component. The transmission component includes transmission rods, which are fixedly connected to each other via an intermediate rod. A circular plate is fixedly connected to the outer side of the intermediate rod.
[0005] Preferably, the circular plate is slidably connected inside the column, the intermediate rod is slidably connected to the sealing plate, and the transmission rod, the intermediate rod, and the column are coaxially arranged.
[0006] Preferably, the exhaust assembly includes an exhaust plate, with multiple L-shaped holes on both outer sides of the exhaust plate, and sliders fixedly connected to both sides of the exhaust plate. The exhaust plate is slidably connected to the sealing cover and the sealing assembly. The upper end of the exhaust plate is exposed outside the sealing cover, and multiple anti-sliding blocks are provided on the upper end of the exhaust plate.
[0007] Preferably, the negative pressure component includes a pull-out plate, with guide posts fixedly connected to each of the four corners of one end of the pull-out plate, and hollow rubber posts installed between the guide posts fixedly connected to one end of the pull-out plate on any side.
[0008] Preferably, the pull-out plate is installed in a cavity inside the base, the cavity is located at the lower end of the sealing assembly, the guide post is slidably connected to the base, one end of the hollow rubber post is fixedly connected to the pull-out plate, and the other end of the hollow rubber post is fixedly connected to the inner wall of the cavity.
[0009] Preferably, the connecting assembly includes a cylindrical shell, a piston plate is slidably connected inside the cylindrical shell, a telescopic spring and a connecting rod are fixedly connected to one end of the piston plate, a vertical groove is opened inside the connecting rod, the connecting rod is disposed inside the telescopic spring, and the other end of the telescopic spring is fixedly connected to the inner wall of the cylindrical shell.
[0010] Preferably, the sealing assembly includes a cover plate, and guide grooves are provided on both sides of the slot in the middle of the cover plate that connects to the exhaust plate. An elastic ring is fixedly connected to the upper end of the guide groove, and the lower end of the elastic ring is fixedly connected to the slider. The slider is slidably connected inside the cover plate through the guide groove.
[0011] Preferably, there are two adsorption components, which are symmetrically arranged on both sides of the connector. The fixing column inside the adsorption component is connected to the cavity opened inside the base. The lateral projection size of the fixing column and the rubber gasket is equal. The rubber gasket is exposed on the outside of the base.
[0012] Preferably, the vertical rod is installed inside a vertical groove opened inside the connecting rod, and the vertical rod is in close contact with the inner wall of the end of the vertical groove away from the column shell.
[0013] Preferably, the following steps are included: Step 1: Install the entire device onto the autonomous navigation vehicle using the connector, connect it to the adapter port, and complete the installation; Step 2: During the connection process between the connector and the adapter, the rubber gasket makes contact simultaneously with the guide post and the automated navigation vehicle. After the connector is fully inserted, the air extraction plate, pushed by the guide post, creates negative pressure inside the cavity and the rubber gasket to further improve the stability of the connection between the connector and the automated navigation vehicle. Step 3: After the 5G communication module is installed, the autonomous navigation vehicle is put into use. During use, when the ambient temperature changes, the thermal expansion material contracts or expands, which in turn pushes the transmission rod on one side of the hollow column to move. During the movement of the transmission rod, the vertical rod moves and controls one of the connecting rods to move. During the movement of the connecting rod, the corresponding piston plate moves, which further evacuates the inside of the fixed column to ensure the stability of the rubber gasket adsorption. Step 4: When you need to remove the connector from the automated navigation vehicle, press down the exhaust plate so that the bottom of the L-shaped hole enters the cavity and connects with the outside. Then you can directly pull the connector off the automated navigation vehicle.
[0014] This invention has at least the following beneficial effects: 1. In this invention, the negative pressure adsorption force automatically generated during insertion significantly enhances the connection stability between the 5G communication module and the vehicle interface, effectively resisting vibration; its unique exhaust design allows for one-click pressure balancing during disassembly, achieving a balance between a firm connection and convenient plugging and unplugging; at the same time, the use of thermal expansion materials to sense temperature changes and automatically compensate for negative pressure ensures the connection reliability of the module during long-term operation in a wide temperature range environment. 2. In this invention, a fully passive intelligent adjustment is adopted. The negative pressure compensation component does not require external energy or electronic control signals. It can respond to changes in ambient temperature and automatically complete negative pressure compensation by relying solely on the physical properties of thermal expansion materials. This passive working mechanism not only reduces the overall power consumption of the module, which is in line with its "low power consumption" design goal, but also eliminates the risk of compensation function failure due to electronic control system failure, greatly improving the reliability and safety of long-term operation in critical tasks. 3. In this invention, the functions of exhaust, negative pressure generation, sealing and compensation are ingeniously integrated into a compact space formed by the base and the sealing cover. This design achieves a high degree of functionality and optimization of the structure. The components work together, for example, the sliding fit between the sealing component and the exhaust component ensures both smooth operation and the sealing of the cavity. The integrated design reduces the complexity of externally exposed mechanisms, effectively prevents the intrusion of dust and moisture, improves the overall protection level and environmental durability of the module, and simplifies the assembly process.

Step 3: After the 5G communication module is installed, the automatic navigation vehicle is put into use. During use, when the ambient temperature changes, the thermal expansion material 6412 contracts or expands, which in turn pushes the transmission rod 6431 on one side of the hollow column 641 to move.
