Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a battery pack coupled grounding antenna. Background Technology

[0002] In the field of IoT smart products, CAT1 communication technology is widely used for signal interaction between devices and the outside world because it is adapted to the requirements of low power consumption and narrowband data transmission. As the core component of CAT1 communication, the performance of the antenna directly determines the communication stability. Currently, most mainstream CAT1 grounding antennas on the market adopt the structural design of FPC and conductive foam or FPC and conductive cloth. The grounding connection between the antenna ground and the metal parts is achieved through conductive foam and conductive cloth to ensure the signal radiation effect.

[0003] However, traditional antennas rely on conductive foam and conductive cloth to achieve grounding, which not only increases the cost of material procurement, but also makes the conductive foam prone to aging and the conductive cloth prone to displacement. During installation, the bonding position needs to be repeatedly calibrated, which is cumbersome. Furthermore, the exposed conductive materials may damage the overall aesthetics of the product. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a battery pack coupled grounding antenna to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery pack coupled grounding antenna, comprising a metal plate, a bracket fixedly connected to the top of the metal plate, an FPC feedback antenna adhered to the top of the bracket, an FPC ground wire adhered to the bottom inner side of the FPC feedback antenna, the bottom of the FPC ground wire adhered to the top of the metal plate, a terminal wire fixedly connected to the top inner side of the FPC feedback antenna, and a terminal block fixedly connected to the back end of the terminal wire.

[0006] Preferably, the terminal wire has a built-in antenna, and the built-in antenna includes a radio signal receiving and transmitting device to realize the signal interaction of CAT1 communication and meet the external communication needs of smart products.

[0007] Preferably, the bracket is made of plastic material, which avoids signal shielding and ensures the signal transmission performance of CAT1 communication.

[0008] Compared with the prior art, the present invention provides a battery pack coupled grounding antenna, which has the following advantages:

[0009] 1. The battery pack coupled ground antenna uses an FPC feedback antenna bonded to a plastic bracket, an FPC ground wire bonded to a metal plate, and a terminal wire paired with a wiring terminal to fasten the ANT end of the module. This design allows for assembly without complicated tools, reducing tedious steps such as bonding calibration and cutting conductive materials, significantly improving installation efficiency, and avoiding secondary debugging problems caused by easy displacement of conductive cloth and easy aging of conductive foam.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] This utility model provides the following technical solution:

[0018] Example 1

[0019] Please see Figure 1-3 This utility model provides a technical solution: a battery pack coupled grounding antenna, including a metal plate 2, a bracket 3 fixedly connected to the top of the metal plate 2, an FPC feedback antenna 4 glued to the top of the bracket 3, an FPC ground wire 5 glued to the bottom inner side of the FPC feedback antenna 4, the bottom of the FPC ground wire 5 glued to the top of the metal plate 2, a terminal wire 1 fixedly connected to the top inner side of the FPC feedback antenna 4, and a wiring terminal 6 fixedly connected to the back end of the terminal wire 1.

[0020] Furthermore, terminal line 1 has a built-in antenna, which includes a radio signal receiving and transmitting device to realize the signal interaction of CAT1 communication and meet the external communication needs of smart products.

[0021] Furthermore, bracket 3 is made of plastic material. The plastic bracket 3 avoids signal shielding and ensures the signal transmission performance of CAT1 communication.

[0022] In actual operation, when this device is used and the smart product needs to communicate with the outside world, during the signal transmission process, the communication module of the smart product's motherboard will convert the data to be transmitted into an electrical signal, which will be transmitted to the signal transmitting device in terminal line 1 through terminal 6. The transmitting device will further convert the electrical signal into a radio signal that conforms to the CAT1 communication frequency band and transmit it to the FPC feedback antenna 4. The impedance matching characteristics of the FPC feedback antenna 4 will be optimized through the FPC ground plane 5, thereby improving the radiation efficiency and receiving sensitivity of the radio signal. During the signal reception process, the radio signal sent by the external base station or communication equipment will be captured by the FPC feedback antenna 4 and transmitted to the signal receiving device in terminal line 1. The receiving device will convert the radio signal into an electrical signal and then transmit it to the smart product's motherboard through terminal 6 to complete the signal interaction.

[0023] The bracket 3 can fix the spatial position of the FPC feedback antenna 4, ensuring that the antenna is always at the preset communication angle and height, avoiding signal radiation direction deviation caused by antenna displacement. The supporting role of the plastic bracket 3 can reduce the deformation of the FPC feedback antenna 4 during equipment vibration and assembly, ensure the integrity of the antenna structure, indirectly maintain the stability of signal transmission and radiation, and provide a reliable structural foundation for the overall communication process.

[0024] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
