[0028] Reference Figure 1 to Figure 2The utility model proposes an anti-interference WIFI receiving device, comprising: a mainboard 1, a connecting seat 2 is arranged on one side of the upper end of the mainboard 1; a signal receiving component 3, comprising a rotating shaft 31, a magnetic ball hinge 32 and a signal receiving rod 33, the rotating shaft 31 is rotatably arranged on the connecting seat 2, the magnetic ball hinge 32 is fixedly arranged on the top of the rotating shaft 31, the signal receiving rod 33 is fixedly connected to the movable end of the magnetic ball hinge 32 to adjust the angle of the signal receiving rod 33, and the magnetic ball hinge 32 can be used to absorb and disperse the energy of interference electromagnetic when the signal passes.

[0029] In the above embodiment, the mainboard 1 is a PBC board, and various circuits can be integrated on the mainboard 1. The connection seat 2 provides a stable support for the signal receiving component 3. Through the cooperation between the rotating shaft 31 and the connection seat 2, the signal receiving component 3 can flexibly adjust its height and tightness on the connection seat 2 to adapt to different use environments and signal source positions. The contact position and contact area between the rotating shaft 31 itself and the connection seat 2 can also be adjusted by rotation to enhance the stability of signal transmission. Specifically, a threaded portion is provided at one end of the rotating shaft 31, and the connection seat 2 is provided with a threaded hole that matches the threaded portion. By rotating the rotating shaft 31, the height and tightness of the rotating shaft 31 on the connection seat 2 can be easily adjusted, thereby adjusting the relative position between the signal receiving component 3 and the mainboard 1.

[0030] The setting of the magnetic ball hinge 32 allows the direction and angle of the signal receiving rod 33 to be flexibly adjusted, further improving the efficiency and stability of signal reception. Specifically, the magnetic ball hinge 32 includes a movable spherical portion and a hinge portion fixedly connected to the rotating shaft 31, and the spherical portion is free to rotate in multiple directions on the hinge portion to achieve flexible adjustment of the angle and direction of the signal receiving rod 33. Furthermore, the magnetic ball hinge 32 is made of magnetic resistance material, and thus has unique electromagnetic absorption and dispersion characteristics, which can effectively absorb and disperse interference electromagnetics when the signal passes through, thereby protecting the terminal device from external electromagnetic interference when receiving WIFI signals, and will not affect its own signal transmission, ensuring stable signal transmission. The signal receiving rod 33 rotates in multiple directions to adapt to different usage environments and signal source locations, thereby achieving efficient and stable signal reception.

[0031] In summary, the rotating shaft 31 cooperates with the connection of the magnetic ball hinge 32, so that the direction and angle of the signal receiving rod 33 can be flexibly adjusted to adapt to different usage environments and signal source positions, thereby improving the efficiency and stability of signal reception. The magnetic ball hinge 32 effectively absorbs and disperses electromagnetic interference, thereby effectively avoiding the influence of external electromagnetic interference and ensuring the stability and efficient transmission of the signal.

[0032] In one embodiment, the connection base 2 is provided with a filter, and the filter is electrically connected to the rotating shaft 31 .

[0033] In the above embodiment, the filter is arranged in the connection seat 2 and is electrically connected to the rotating shaft 31 to ensure that the signal can be filtered by the filter during the transmission process, thereby further eliminating or reducing the possible interference signal and improving the anti-interference ability of the WIFI receiving device. The filter can selectively allow signals of a specific frequency to pass through while blocking signals of other frequencies, so that noise and interference can be effectively removed during signal transmission, and the purity and stability of the signal can be improved. In addition, the setting of the filter can also effectively protect the signal receiving component 3 from damage by electromagnetic interference and extend its service life. Further, a signal processing module electrically connected to the filter is also provided on the mainboard 1. As an important component of the mainboard 1, the signal processing module is electrically connected to the filter, and can further refine the signal processed by the filter. Through the signal processing module, the signal can be modulated, demodulated, encoded, decoded, etc., so as to ensure the quality and stability of the signal; at the same time, the signal can be converted and adapted as needed, so that the WIFI receiving device can adapt to different communication protocols and signal formats.

[0034] In one embodiment, the mainboard 1 is provided with at least one grounding port 4 , which is cylindrical and plugged into the mainboard 1 for connecting to a grounding system.

[0035] In the above embodiment, at least one grounding port 4 is provided on the mainboard 1, preferably two. The grounding port 4 is connected to the grounding system to provide a stable grounding environment. The setting of the grounding system can effectively prevent the influence of electrostatic interference and electromagnetic radiation on the WIFI receiving device, and ensure the stability and reliability of signal transmission. The grounding port 4 is connected to the circuit of the mainboard 1, and can introduce the charge in the circuit into the earth, thereby eliminating or reducing the electromagnetic interference that may be caused by the accumulation of charge. At the same time, the grounding system can also provide a safe operating environment for the WIFI receiving device to avoid dangerous situations caused by electrical failures and the like. Therefore, the setting of the grounding port 4 is an important role for the WIFI receiving device in further improving the anti-electromagnetic interference capability and operating stability.

[0036] In one embodiment, a cooling plate 5 is further included, and a cooling surface of the cooling plate 5 is attached to the main board 1 .

[0037] In the above embodiment, in the WIFI receiving device, the mainboard 1 serves as the carrier of the entire circuit, and various electronic components are integrated thereon. These components will generate a certain amount of heat when working due to the influence of internal resistance. If the heat cannot be dissipated in time, it may cause the WIFI receiving performance to deteriorate, such as the rate to slow down, and may even damage the electronic components. Therefore, in order to maintain the normal operation of the WIFI receiving device and extend its service life, effective heat dissipation measures need to be taken. By laying a cooling sheet 5 above the mainboard 1, the temperature of the mainboard 1 can be effectively reduced, and the stability and reliability of the device can be improved. The cooling sheet 5 preferably adopts a small-volume cooling sheet 5, and its working principle is to apply a voltage at the junction of two different materials and use the thermoelectric properties of the material to achieve heat transfer and conversion. The cooling sheet 5 can quickly take away the heat generated on the mainboard 1 and dissipate it into the air, thereby keeping the mainboard 1 working in a relatively low temperature range.

[0038] In addition, the laying position and laying area of ​​the cooling sheet 5 can be adjusted according to actual needs to ensure that it can maximize the heat dissipation effect. The cooling sheet 5 can also be combined with the heat sink or other heat dissipation structure on the mainboard 1 to form a more efficient heat dissipation system, further improving the heat dissipation performance of the WIFI receiving device. In summary, by laying the cooling sheet 5 on the mainboard 1 of the WIFI receiving device, the temperature of the mainboard 1 can be effectively reduced, the stability and reliability of the device can be improved, and its service life can be extended. This improvement not only improves the performance of the WIFI receiving device, but also provides a more reliable guarantee for its application in various complex environments.

[0039] In one embodiment, a temperature sensor 6 and a temperature controller 7 are further provided. The temperature sensor 6 is fixedly connected to the mainboard 1 , and the temperature controller 7 is electrically connected to the temperature sensor 6 and the cooling plate 5 .

[0040] In the above embodiment, in the WIFI receiving device, in order to achieve accurate control of the temperature of the mainboard 1 and further improve the stability and reliability of the device, the present embodiment particularly introduces a temperature sensor 6 and a temperature controller 7. The temperature sensor 6 is fixedly connected to the mainboard 1, and can sense the temperature change of the mainboard 1 in real time, and feed back the temperature information to the temperature controller 7. The temperature controller 7 is electrically connected to the cooling plate 5 according to the received temperature information, and intelligently adjusts the working state of the cooling plate 5 to achieve accurate control of the temperature of the mainboard 1. Specifically, when the temperature of the mainboard 1 is too high, the temperature sensor 6 will send a signal to the temperature controller 7 in time, and the temperature controller 7 will immediately start the cooling plate 5 for heat dissipation after receiving the signal. On the contrary, when the temperature of the mainboard 1 is reduced to a suitable range, the temperature controller 7 will adjust the working state of the cooling plate 5 to avoid waste of resources caused by excessive heat dissipation. In this way, the temperature controller 7 can flexibly adjust the working mode of the cooling plate 5 according to the actual temperature of the mainboard 1 to achieve a dynamic balance of temperature.

[0041] In addition, the combination of the temperature sensor 6 and the temperature controller 7 can also be set to provide a temperature monitoring and alarm function. When the temperature of the mainboard 1 exceeds the preset safety threshold, the temperature controller 7 can trigger the alarm mechanism to remind the user to handle it in time, thereby avoiding equipment damage or performance degradation caused by excessive temperature. In summary, this embodiment constructs an intelligent temperature control system together with the cooling plate 5 by setting the temperature sensor 6 and the temperature controller 7. The system can realize real-time monitoring and precise control of the temperature of the mainboard 1, effectively improve the stability and reliability of the WIFI receiving device, and provide users with a more stable and efficient WIFI receiving experience.

[0042] In one embodiment, a plug connector 8 is disposed on one side of the mainboard 1 , and the plug connector 8 extends from one side in the length direction of the mainboard 1 for transmitting received signals.

[0043] In the above embodiment, in order to facilitate the connection and signal transmission between the WIFI receiving device and other devices, a plug connector 8 is provided on one side of the mainboard 1 in this embodiment. As an interface between the mainboard 1 and the external device, the plug connector 8 can conveniently realize the transmission and reception of signals. Through the plug connector 8, the WIFI receiving device can be connected to other devices (such as routers, switches, etc.) to realize the input and output of signals, which not only improves the versatility and flexibility of the WIFI receiving device, but also facilitates the installation and use of users. At the same time, the design of the plug connector 8 also takes into account the stability and anti-interference ability of the signal, and adopts high-quality connectors and transmission lines to ensure the quality and stability of the signal during the transmission process. In addition, the plug connector 8 can also be expanded and upgraded as needed to meet the needs of different application scenarios.

[0044] In one embodiment, a dustproof ring 9 is further included, and the dustproof ring 9 is sleeved on the root of the plug connector 8 .

[0045] In the above embodiment, in order to ensure the durability and transmission efficiency of the WIFI receiving device and prevent dust and debris from entering the plug connector 8 to cause poor contact or damage, the dust ring 9 is tightly sleeved at the root of the plug connector 8. When the plug connector 8 is plugged into other receiving terminals, the dust ring 9 forms an effective protective barrier on the outside, which can block the invasion of external dust and debris. The material of the dust ring 9 is soft and durable rubber or silicone material, which has good elasticity and sealing performance to ensure long-term and effective dustproof effect. At the same time, the dust ring 9 also takes into account the convenience and reliability of installation. It can be easily sleeved at the root of the plug connector 8 and is not easy to fall off or shift. By setting the dust ring 9, not only can the service life of the WIFI receiving device be extended, the failure and maintenance costs caused by dust and debris can be reduced, but also the stability of the device and the signal transmission quality can be improved.

[0046] In one embodiment, a signal terminal 10 is disposed at the top of the signal receiving rod 33 , and the signal terminal 10 is spiral-shaped.

[0047] In the above embodiment, in order to improve the signal receiving ability and stability of the WIFI receiving device, a spiral signal terminal 10 is particularly provided at the top of the signal receiving rod 33. The signal terminal 10 adopts a spiral design, which can increase the receiving area and receiving range of the signal and improve the receiving efficiency of the signal. At the same time, the spiral structure can also enhance the stability and anti-interference ability of the signal, reduce the attenuation and interference of the signal during the transmission process, so that the WIFI receiving device can still maintain stable signal reception and transmission when the signal is weak or there is interference, thereby improving the user's network experience. In addition, the signal terminal 10 can also be adjusted and optimized as needed to meet the needs of different environments and application scenarios. Therefore, by adopting the design of the spiral signal terminal 10, the signal receiving ability and stability of the WIFI receiving device can be significantly improved.

[0048] In one embodiment, a signal amplifier is further included, which is disposed on the main board 1 , and the signal amplifier is electrically connected to the signal receiving rod 33 .

[0049] In the above embodiment, the signal amplifier can effectively improve the signal receiving capability and transmission efficiency of the WIFI receiving device. The signal amplifier is set on the mainboard 1, integrated with the mainboard 1 on the circuit of the PCB, and electrically connected to the signal receiving rod 33. The signal amplifier can enhance the strength of the received WIFI signal and improve the transmission quality and stability of the signal. When the signal receiving rod 33 receives the WIFI signal, the signal will be transmitted to the signal amplifier on the mainboard 1 for amplification processing. The signal strength after amplification is significantly improved, and it can be more stably transmitted to the internal processing unit of the device, thereby improving the signal receiving capability and transmission efficiency of the entire WIFI receiving device. The signal amplifier can effectively solve the problems of signal attenuation and interference, and improve the performance and stability of the WIFI receiving device. At the same time, the introduction of the signal amplifier also makes the WIFI receiving device more suitable for complex environments and long-distance transmission scenarios, providing users with a smoother and more stable network experience. Therefore, by setting a signal amplifier, this embodiment significantly improves the signal receiving capability and transmission efficiency of the WIFI receiving device, and provides users with better network services.

[0051] In the above embodiment, the dustproof housing 11 is used to isolate dust on the circuit board, which can effectively reduce the risk of circuit failure. The heat dissipation fins 12 are arranged on the surface of the dustproof housing 11 to further enhance the heat dissipation effect. The dustproof housing 11 is tightly sleeved on the outside of the mainboard 1 and is made of a lightweight heat-conductive material, such as aluminum alloy. It has good dustproof, waterproof and impact-proof properties and can effectively protect the mainboard 1 and the internal circuit from the external environment. At the same time, the design of the dustproof housing 11 also takes into account the heat dissipation performance. By arranging the heat dissipation fins 12 on its surface, the heat dissipation area is increased and the heat dissipation efficiency is improved. The heat dissipation fins 12 are arranged as a whole with the dustproof housing 11 and are made of the same material. They can quickly conduct the heat generated by the mainboard 1 to the surface of the housing, and dissipate the heat into the air through natural convection or fan-assisted heat dissipation, thereby maintaining the temperature of the mainboard 1 stable. By arranging the dustproof housing 11 and the heat dissipation fins 12, the WIFI receiving device can not only effectively resist the influence of the external environment, but also maintain good heat dissipation performance, ensuring that the device can operate stably in a high temperature environment.
