Description

Technical Field

[0001] This utility model relates to the field of communication modules, specifically to a communication module with a built-in antenna. Background Technology

[0002] In today's era of rapid digital and information technology development, communication modules, as core components for enabling wireless communication between devices, are widely used in numerous technological fields such as smart homes, industrial IoT, intelligent transportation, and telemedicine. They connect various smart devices to networks, enabling real-time data transmission and interaction, and providing crucial technical support for intelligent control, remote monitoring, and management of equipment.

[0003] In the field of radio frequency (RF) antenna lighting fixtures, the application of communication modules is becoming increasingly widespread. These fixtures typically integrate lighting and wireless communication functions, connecting to intelligent control systems via built-in communication modules to remotely control the lights, adjust brightness, and change colors. Existing communication modules in RF antenna lighting fixtures generally include a baseband processing unit, an RF transceiver unit, and an external antenna. The external antenna is primarily used to receive wireless signals, and its performance and installation location significantly impact the communication effectiveness of the lighting fixture.

[0004] However, existing communication modules have certain shortcomings in practical applications. Among them, the antenna structure of existing radio frequency antennas is relatively simple, and they are generally spirally mounted on the PCB board, which affects the aesthetics of the communication module. In addition, the communication receiving area of ​​these antennas is small, which affects the communication quality and stability of the communication module. Furthermore, existing communication modules are generally directly exposed, making them susceptible to the influence of the external environment, such as collisions, squeezing, and moisture, which can easily lead to fault risks such as poor contact and maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a communication module with a built-in antenna, so as to solve the technical problems in the background art where the antenna structure of the existing communication module has a small receiving area, which affects the communication quality and stability, and the existing communication module lacks a protective structure, which affects the effective protection of the communication module components.

[0006] The objective of this utility model is achieved through the following means:

[0007] A communication module with a built-in antenna includes a PCB board, on which a control module is connected. A connection terminal is provided on the surface of the PCB board, and an antenna structure is electrically connected to the PCB board through the connection terminal. An inner cavity is formed inside the antenna structure to cover the control module, so that the antenna structure covers and protects the control module through the inner cavity.

[0008] Furthermore, as described above, the bottom of the PCB board is provided with multiple soldering slots, and each of the multiple soldering slots is connected to a surface-mount pin for soldering.

[0009] The bottom of the PCB board has multiple soldering slots and connects to surface-mount pins, which facilitates stable soldering connections between the communication module and other devices, ensuring reliable installation of the communication module in the circuit. At the same time, the surface-mount pin configuration is simpler and more aesthetically pleasing than through-hole pins, and the surface-mount pins ensure reliable soldering of the communication module.

[0010] Furthermore, as described above, the side of the antenna structure is bent to form a protective edge, making the antenna structure a shell cover, and the antenna structure is formed into an inner cavity by stamping.

[0011] The antenna structure features a protective edge formed by bending on the side, which acts as a cover to further enhance the protection of the internal control module. At the same time, the internal cavity can wrap and protect the control module on the PCB board, further enhancing the protection against compression, impact, and water damage.

[0012] Furthermore, as described above, the cross-section of the antenna structure is rectangular, circular, or polygonal.

[0013] The antenna structure has a rectangular, circular, or polygonal cross-section, allowing for the selection of a suitable shape based on actual needs and installation space. This increases the flexibility of antenna structure design, meets the usage requirements of different scenarios, and also helps optimize the performance of the antenna structure.

[0014] Furthermore, as described above, the outer surface of the antenna structure forms a receiving surface, and the antenna structure is provided with a chamfer.

[0015] The outer surface of the antenna structure forms a receiving surface, which increases the receiving area of ​​the antenna and helps to improve the communication quality and stability of the communication module. The chamfering can avoid the antenna structure edges being too sharp, reducing the safety hazards such as scratches to other parts or personnel during installation and use, while also improving the aesthetics of the product.

[0016] Furthermore, as described above, the control module is mounted on the upper surface of the PCB board by soldering, the connection end is located on the upper surface of the PCB board, the antenna structure is electrically connected to the connection end, and the length and width of the antenna structure are matched with the length and width of the PCB board, or are smaller than the length and width of the PCB board.

[0017] The control module is mounted on the upper surface of the PCB board via soldering, and the connection terminal is also located on the upper surface, which facilitates electrical connection between the antenna structure and the connection terminal, ensuring the stability and reliability of signal transmission. The length and width of the antenna structure are matched with or smaller than the PCB board, making the overall layout of the antenna structure and the PCB board more compact and reasonable. This ensures that the antenna structure can protect the control module without affecting the overall size and installation convenience of the communication module due to the antenna structure being too large.

[0018] The beneficial effects of this utility model are as follows: The antenna structure is mounted on the PCB board. Compared with the traditional spiral antenna, this structure effectively increases the effective radiation area of ​​the antenna, thereby enhancing the signal reception capability, improving the communication quality and stability of the communication module, and protecting the control module on the PCB board through the inner cavity of the antenna structure. This effectively isolates the direct impact of the external environment on the control module, such as collision, squeezing, moisture, etc., reducing the risk of failures such as poor contact caused by external factors, reducing maintenance costs, and extending the service life of the communication module. The utility model also makes the overall appearance of the communication module simpler and more beautiful by mounting the antenna structure on the PCB board, improving the overall visual effect of the product.
