Description

Technical Field

[0001] The present application relates to the field of wireless network technology, and in particular to a portable 5G HDMI Dongle device. Background Art

[0002] With the popularity of smart devices and the increase in high-definition video content, users have an increasing demand for wirelessly projecting content on mobile devices onto large screens. The development and popularization of 5G communication technology, the high-speed transmission capability and low-latency characteristics of 5G networks make it possible to achieve wireless transmission of high-definition video. At the same time, HDMI, as a high-definition video and audio transmission standard, provides convenience for connecting to display devices. The portable 5G HDMI Dongle came into being to meet this market demand.

[0003] The existing 5G HDMI Dongle can be paired with a mobile device through a wireless connection (such as Wi-Fi or Bluetooth) to receive video and audio signals from the mobile device. It can also be connected to a large-screen display device (such as a TV or monitor) through an HDMI interface to output the content received on the mobile device to the large screen.

[0004] However, when the signal strength fluctuates greatly or the signal environment is unstable, the signal may be blocked and interfered by objects such as walls and furniture, resulting in large fluctuations in signal strength. Existing equipment usually performs signal enhancement according to a preset fixed strategy, which makes it difficult to perceive signal changes in time and make corresponding adjustments. Therefore, when the signal is weak, users may encounter problems such as video freezes and blurred images, which seriously affects the user experience. Summary of the invention

[0005] The present application provides a portable 5G HDMI Dongle device, which is used to intelligently enhance the 5G signal by using a deep learning model to adapt to different environments, thereby providing users with stable and reliable 5G signal transmission, in the case where the 5G signal is easily affected by the environment and is unstable in the prior art.

[0006] In the first aspect, the present application provides a portable 5G HDMI Dongle device, comprising: a shell for protecting the internal components of the device; a signal enhancement module, which is used to detect the received 5G signal in real time after receiving the matching information of the mobile device, analyze the 5G signal through a preset deep learning model, determine the signal characteristics in the 5G signal, and judge whether the strength and quality of the 5G signal are lower than a preset threshold value according to the signal characteristics, and start signal enhancement if it is lower than the preset threshold value, and the deep learning model is obtained by training based on actual 5G signal transmission data in multiple different environments as a training set sample; a communication module, which is in communication connection with the signal enhancement module, and is used to transmit the 5G signal after the signal enhancement module. The 5G signal processed by the block is sent to the mobile device and the display device for data communication; an HDMI interface is used to connect the communication module and the external display device to transmit the processed 5G signal; a control module is communicatively connected to the signal enhancement module, and the control module is used to control the display device to display the information to be displayed of the mobile device according to the 5G signal processed by the signal enhancement module; a storage module is used to store the deep learning model in the signal enhancement module, the setting information of the preset threshold and the information to be displayed; an antenna is arranged on one side of the device, and is used to receive the initial 5G signal and send the 5G signal processed by the signal enhancement module.

[0007] By adopting the above technical solutions, the signal strength and quality can be accurately judged and enhanced according to different environments. This allows the mobile devices and display devices connected by users to receive stable and high-quality 5G signals in various complex environments, avoiding problems such as freezes and delays caused by weak signals, improving the smoothness of data communication and the display effect of display devices, and bringing users a better user experience, whether watching high-definition videos or conducting real-time interactions.

[0008] In combination with some embodiments of the first aspect, in some embodiments, the signal enhancement module includes an environmental sensor and a central processor, the environmental sensor is used to monitor the signal environment parameters in the target environment in real time, the central processor receives the signal environment parameters, and determines the optimal signal enhancement strategy for improving the 5G signal quality and strength in the target environment based on the pre-trained deep learning model combined with the signal environment parameters. The optimal signal enhancement strategy refers to a strategy to enhance the signal by optimizing the parameters in the communication protocol.

[0009] By adopting the above technical solutions, the optimal signal enhancement strategy can dynamically optimize the communication protocol parameters for different environments, improve the pertinence and effectiveness of signal enhancement, and provide high-quality 5G signals for mobile devices and display devices in various complex environments, thereby improving the user experience.

[0010] In combination with some embodiments of the first aspect, in some embodiments, a power module is also included, which includes a rechargeable battery and a charging interface. The rechargeable battery is used to provide power support for the entire device, and the charging interface is used to connect to an external power source to charge the rechargeable battery. It also supports direct powering of the device by connecting to an external power source during use.

[0011] By adopting the above technical solution, the portability of the device is increased, so that the user can use the device even without an external power supply.

[0012] In combination with some embodiments of the first aspect, in some embodiments, a drop detection module is further included, which is used to detect whether the device has been dropped on the ground. The drop detection module includes an acceleration sensor and a microcontroller. The acceleration sensor is used to monitor the acceleration changes of the device in real time. When it is detected that the acceleration change increases instantaneously and exceeds a preset acceleration threshold, it is determined that the device has been dropped, and a drop signal is sent to the microcontroller. After receiving the drop signal, the microcontroller activates a preset data protection mechanism to prevent data loss. At the same time, the microcontroller sends a drop prompt message to the set mobile device.

[0013] By adopting the above technical solution, when a fall is detected, the acceleration sensor can quickly and accurately detect the abnormal movement of the device, and the timely response of the microcontroller can effectively prevent data loss and protect user data security. At the same time, a prompt message is sent to the mobile device so that the user can understand the device status in time and take corresponding measures.

[0014] In combination with some embodiments of the first aspect, in some embodiments, a positioning module is also included for obtaining geographic location information of the device. When the device is connected to the mobile device and the mobile device sends a location information viewing request instruction, the positioning module sends the geographic location information to the mobile device via wireless transmission.

[0015] By adopting the above technical solution, the location information of the device is provided to the user, so that the user can quickly find the device when needed.

[0016] In combination with some embodiments of the first aspect, in some embodiments, an importance level sorting module is further included, which is communicatively connected to the control module and the communication module. When the communication module simultaneously receives information to be displayed from multiple mobile devices, a first communication device determination instruction is sent to the control module. After the control module receives the communication device determination instruction, the device priorities of the multiple mobile devices are determined, and the mobile device with the highest device priority is determined as the first communication device. If, during the period when the first communication device is using the device, the second communication device sends information to be displayed to the communication module more than a number threshold, the control module sends a prompt to the first communication device whether to allow the information to be displayed to be changed. If feedback information from the first communication device that allows the change is received, the display device is controlled to display the information to be displayed sent by the second communication device.

[0017] By adopting the above technical solution, when multiple devices compete to use the device, resources can be reasonably allocated according to priority, giving priority to meeting the needs of important devices. At the same time, when the secondary priority device has an urgent need, it can be switched through the prompt and confirmation mechanism, thereby improving the efficiency and flexibility of the device.

[0018] In combination with some embodiments of the first aspect, in some embodiments, a verification module is also included for performing identity authentication when connecting a device. The verification module has a built-in fingerprint recognition chip, which is used to collect the user's fingerprint information and match it with a preset fingerprint template stored in the storage module. If the match is successful, the connection is allowed, otherwise the connection is rejected to achieve identity authentication of the connecting device.

[0019] By adopting the above technical solutions, fingerprint recognition has a high degree of security and uniqueness, which can effectively prevent unauthorized use and protect user data security and privacy.

[0020] In combination with some embodiments of the first aspect, in some embodiments, a display prompt module is also included, which is connected to the verification module and the control module, and is used to display a verification failure prompt message when the verification module fails in verification. The control module is also used to send a failure prompt signal to the display prompt module when receiving a verification failure signal from the verification module, and control the display prompt module to display the verification failure prompt message.

[0021] By adopting the above technical solution, verification failure information can be fed back in a timely manner, which enables users to understand the verification status in a timely manner.

[0022] In combination with some embodiments of the first aspect, in some embodiments, a counting module is arranged between the verification module and the control module, and the counting module is used to record the number of verification failures and send the number of verification failures to the control module; the control module is also used to determine whether the number of verification failures exceeds a preset number threshold. If the number of verification failures exceeds the preset number threshold, the locking device can only be verified again after a preset time.

[0023] By adopting the above technical solution, the security of the device is further enhanced to prevent malicious connection attempts. When the number of verification failures exceeds a preset threshold, the device is locked, which can effectively prevent continued attempts by illegal users, protect user data security and normal use of the device.

[0024] In combination with some embodiments of the first aspect, in some embodiments, an antenna storage component is further included for storing the antenna, and the antenna storage component includes an antenna box having a cavity for accommodating the antenna; an antenna folding mechanism for driving the antenna to be retracted and folded; and an elastic snap mechanism for realizing automatic pop-up and snap-on fixation of the antenna.

[0025] By adopting the above technical solution, the antenna box, antenna folding mechanism and elastic buckle mechanism in the antenna storage component work together to facilitate the storage and use of the antenna, making the device more convenient to carry and use, thereby improving the portability and ease of use of the device.

[0026] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages: 1. Since the signal enhancement module uses a deep learning model to analyze and enhance the 5G signal, it effectively solves the problems of unstable 5G signals, prone to freezes and delays in different environments in the existing technology, thereby achieving the technical effect of providing stable and high-quality 5G signals for mobile devices and display devices, improving data communication fluency and display effects, and bringing users a better user experience.

[0027] 2. Due to the technical means of the acceleration sensor and the microcontroller working together in the fall detection module, the problem in the prior art that the accidental drop of the device may cause data loss and the user cannot be informed in time is effectively solved, thereby achieving the technical effect of timely starting the data protection mechanism when the device falls to prevent data loss, and sending a drop prompt information to the mobile device, so that the user can understand the status of the device in time.

[0028] 3. Due to the technical means of using the importance level sorting module to determine the device priority and perform display switching control, the problem of unreasonable resource allocation when multiple mobile devices are connected at the same time in the prior art is effectively solved, thereby realizing reasonable allocation of resources according to device priority, giving priority to meeting the needs of important devices, and at the same time, through the prompt and confirmation mechanism, switching is performed when there is an urgent need for the secondary priority device, thereby improving the technical effect of improving the efficiency and flexibility of device use.

[0033] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] The embodiment of the present application provides a portable 5G HDMI Dongle device. For ease of understanding, the structure of the device is first introduced below. Figure 1 As shown, Figure 1 This is an exemplary structural diagram of an embodiment of the present application: Figure 1 The display shows a partial structure of a portable 5G HDMI Dongle device, in which an HDMI interface 4 is arranged on one side of the device for docking with a display device. The housing 1 is made of hard plastic material to protect the sensitive structure inside the device from impact and extrusion by the external environment. The signal enhancement module 2, the communication module 3, the control module 5 and the storage module 6 are all arranged inside the housing 1. The signal enhancement module 2 is used to analyze and judge the strength and quality of the 5G signal, and start the enhancement when the signal is weak. The communication module 3 is responsible for receiving and transmitting 5G signals with the mobile device and the display device. The control module 5 is used to control the display content of the display device. The storage module 6 is used to store data such as the deep learning model of the signal enhancement module 2. The antenna 7 is arranged on the other side of the device, which can receive the initial 5G signal from the base station. At the same time, after the signal is processed and enhanced by the enhancement module, the antenna 7 is also responsible for sending the enhanced 5G signal to the mobile device and the display device. The setting of the antenna 7 allows the device to have a better signal transmission and reception effect. Through the coordinated work of each module, the device can provide stable and high-quality 5G signal transmission to achieve wireless screen projection display of mobile device content.

[0035] The present application embodiment provides a portable 5G HDMI Dongle device, such as Figure 2 As shown, Figure 2 It is a module connection diagram of an embodiment of the present application, including: Shell 1, used to protect the internal components of the device; Signal enhancement module 2 is used to detect the received 5G signal in real time after receiving the matching information of the mobile device, analyze the 5G signal through a preset deep learning model, determine the signal characteristics in the 5G signal, and judge whether the strength and quality of the 5G signal are lower than a preset threshold value according to the signal characteristics, and start signal enhancement if it is lower than the preset threshold value. The deep learning model is obtained by training with actual 5G signal transmission data in multiple different environments as training set samples; The communication module 3 is connected to the signal enhancement module 2 for transmitting the 5G signal processed by the signal enhancement module 2 to the mobile device and the display device for data communication; An HDMI interface 4, used to connect the communication module 3 and an external display device to transmit the processed 5G signal; A control module 5 is connected to the signal enhancement module 2 for controlling the display device to display the information to be displayed of the mobile device according to the 5G signal processed by the signal enhancement module 2; A storage module 6, used for storing the deep learning model in the signal enhancement module 2, the setting information of the preset threshold and the information to be displayed; The antenna 7 is arranged on one side of the device and is used to receive the initial 5G signal and send the 5G signal processed by the signal enhancement module 2.

[0036] Specifically, when the network 5G signal is unstable, the user connects the HDMI interface 4 of the device to the interface corresponding to the display device, and the user matches his mobile device with the device in advance. At the same time, the user's mobile device matching information can be stored in the storage module 6 by wireless verification, so that the user can directly use the device next time without matching again. The user then displays the video or other information to be displayed on the display device through the set channel, and then the signal enhancement module 2 will receive the relatively weak or unstable 5G signal in the current 5G network environment in real time. The preset deep learning model in this module has been trained with a large number of actual 5G signal transmission data in different environments, and can accurately analyze the parameter characteristics of the currently received signal. For example, it is determined that the center frequency of the 5G signal is 5.8GHz, the phase noise reaches 30 degrees, and the received signal strength is only -80dBm. After deep learning model analysis, it can be determined that the signal quality is lower than the preset acceptable quality threshold of -70dBm, and the signal enhancement process needs to be started to improve the 5G signal in the current environment. The signal enhancement unit in the signal enhancement module 2 will automatically select the best signal enhancement strategy in the current environment based on the output after the deep learning model operation. For example, the model determines that the best effect is achieved by increasing the wireless transmission power of the mobile device to amplify the signal. Therefore, the signal enhancement unit instructs the mobile device to adjust the wireless transmission power to 10dBm, 5dBm higher than the original, to enhance the wireless screen projection signal to improve the projection effect. After increasing the transmission power, the mobile device will transmit the enhanced standard radio signal that complies with the 5G protocol to the communication module 3 of the device. Then, the communication module 3 will transmit the video stream data to the connected display device through the HDMI interface 4, using the HDMI specification with a transmission rate of up to 10Gbps, and finally realize the wireless screen projection playback of the mobile device.

[0037] For ease of understanding, the following further describes the modules of the device provided by this embodiment in combination with the above content. Figure 3 , Figure 3 This is another module connection diagram of an embodiment of the present application.

[0038] exist Figure 3 In the portable 5G HDMI Dongle device, the signal enhancement module 2 includes an environmental sensor 8 and a central processor 9. The environmental sensor 8 is used to monitor the signal environment parameters in the target environment in real time. The central processor 9 receives the signal environment parameters and determines the best signal enhancement strategy to improve the quality and strength of the 5G signal in the target environment according to the pre-trained deep learning model combined with the signal environment parameters. The best signal enhancement strategy refers to a strategy to enhance the signal by optimizing the parameters in the communication protocol. Specifically, the environmental sensor 8 in the signal enhancement module 2 can detect the wireless signal state parameters of the current environment of the device in real time, such as spectrum energy distribution, adjacent frequency band interference level, multipath effect parameters, etc. For example, the sensor detects that the center frequency energy of the 5G signal in the current environment is weak, while the energy of the adjacent WiFi signal is high, and it is judged that there is a more serious adjacent channel interference. At this time, the environmental sensor 8 will immediately transmit the detected signal environment parameters, including spectrum distribution, path loss, signal-to-noise ratio, etc., to the central processor 9 in the signal enhancement module 2. The central processor 9 integrates a signal optimization model trained based on a deep learning algorithm. It can infer the best signal enhancement strategy in the current environment based on the current signal environment parameters reported by the sensor and combined with the deep learning model. For example, the model predicts that based on environmental parameters, the best strategy is to adjust the transmission channel width to avoid interference from some adjacent frequency bands by reducing the transmission bandwidth. The central processor 9 can send a control instruction to the mobile device, instructing it to adjust the channel bandwidth to 100MHz to optimize the wireless transmission effect. Through such a mechanism, the environmental sensor 8 plays the role of real-time detection of the signal environment, and the central processor 9 uses a deep learning model to output the optimal signal enhancement strategy based on the sensor parameters. This method combines environmental perception and intelligent optimization, which can significantly improve signal quality and transmission robustness, and provide mobile devices with clearer and smoother screen projection effects.

[0039] In some embodiments, the portable 5G HDMI Dongle device also includes a power module 10, which includes a rechargeable battery 11 and a charging interface 12. The rechargeable battery 11 is used to provide power support for the entire device, and the charging interface 12 is used to connect an external power source to charge the rechargeable battery 11. It also supports directly powering the device by connecting an external power source during use. Specifically, the power module 10 is integrated with a USB charging interface 12, which can provide a wired external power supply for the device. When the device is connected to a display device via an HDMI cable, a USB cable can be used to connect the USB interface or power adapter on the display device, and the system is directly powered by the charging interface 12, which avoids the problem of battery power consumption during long-term use. The charging interface 12 can also realize low-current charging through a computer USB port. When the device is connected to a laptop computer for work, its battery can be charged slowly. When an external power source is connected through the charging interface 12, the rechargeable battery 11 will automatically enter the charging state, and can be fully charged within 1.5 hours through the fast charging protocol. At this time, the external power supply can directly provide working current for the system. If the external power supply is suddenly disconnected, the rechargeable battery 11 can quickly switch to a discharge state, ensuring that the system can immediately switch to a battery-powered mode to prevent the device from suddenly losing power.

[0040] In some embodiments, the portable 5G HDMI Dongle device also includes a drop detection module 13 for detecting whether the device has been dropped on the ground. The drop detection module 13 includes an acceleration sensor 14 and a microcontroller 15. The acceleration sensor 14 is used to monitor the acceleration change of the device in real time. When it is detected that the acceleration change increases instantly and exceeds the preset acceleration threshold, it is determined that the device has dropped, and a drop signal is sent to the microcontroller 15. After receiving the drop signal, the microcontroller 15 starts the preset data protection mechanism to prevent data loss, and the microcontroller 15 sends a drop prompt message to the set mobile device. For example, when a user accidentally drops the portable 5GHDMI Dongle device from his hand or accidentally drops it from a high place, the acceleration sensor 14 will immediately detect this sharp acceleration change. If the detected acceleration change increases instantly and exceeds the preset acceleration threshold, it can be determined that the device has dropped. This preset acceleration threshold is carefully set to ensure that the drop event can be accurately detected while avoiding misjudgment. For example, in actual testing, a suitable acceleration threshold can be determined by simulating falling conditions at different heights, so that the detection mechanism is triggered only when a fall actually occurs. Once the acceleration sensor 14 determines that the device has fallen, it will immediately send a falling signal to the microcontroller 15. After receiving the falling signal, the microcontroller 15 will quickly start the preset data protection mechanism. The purpose of this data protection mechanism is to prevent data loss that may occur during the falling process. Specifically, it may include the following measures. First, the microcontroller 15 can immediately suspend the ongoing data transmission to avoid data loss caused by data transmission interruption. Secondly, it can temporarily store the data being processed to ensure the integrity of the data. For example, if the device is transmitting high-definition video data, the microcontroller 15 can suspend the transmission of the video stream and cache the data that has been received but not yet processed, and continue processing after the device returns to normal. At the same time, the microcontroller 15 will also send a falling prompt message to the set mobile device, because the user can learn about the falling situation of the device in time through the mobile device. For example, the user's mobile phone can receive a falling prompt message to remind the user that the device may have been damaged and needs to be checked. In this way, the user can take timely measures to avoid further damage due to continued use of the device without knowing it has fallen.

[0041] In some embodiments, the portable 5G HDMI Dongle device also includes a positioning module 16 for obtaining the geographic location information of the device. When the device is connected to the mobile device and the mobile device sends a location information viewing request instruction, the positioning module 16 sends the geographic location information to the mobile device via wireless transmission. Specifically, the positioning module 16 can obtain geographic location information by using the global positioning system (GPS), the Beidou satellite navigation system, or by interacting with a mobile network base station. When the portable 5G HDMI Dongle device is connected to the mobile device, a data transmission channel is established between the two. In this connection state, if the mobile device sends a location information viewing request instruction, the positioning module 16 will respond quickly. Once the positioning module 16 receives this request instruction, it will immediately send the acquired geographic location information to the mobile device via wireless transmission. After the mobile device receives this information, it can display the location of the device on the screen, or combine it with the map software to display the specific location of the device in a more intuitive way. By connecting to the mobile device and responding to the location information viewing request instruction, the positioning module 16 can send the geographic location information of the device to the mobile device in a timely and accurate manner, which brings great convenience to the user's use and management.

[0042] In some embodiments, the portable 5G HDMI Dongle device further includes an importance level sorting module 17, which is connected to the control module 5 and the communication module 3. When the communication module 3 receives information to be displayed from multiple mobile devices at the same time, it sends a first communication device determination instruction to the control module 5. After the control module 5 receives the communication device determination instruction, it determines the device priorities of multiple mobile devices, and determines the mobile device with the highest device priority as the first communication device. If the second communication device sends information to be displayed to the communication module 3 more times than the number threshold during the use of the first communication device, the control module 5 sends a prompt to the first communication device whether to allow the replacement of the information to be displayed. If the feedback information that the first communication device allows the replacement is received, the display device is controlled to display the information to be displayed sent by the second communication device. Specifically, when the communication module 3 receives information to be displayed from multiple mobile devices at the same time, the situation becomes complicated. At this time, the communication module 3 sends a first communication device determination instruction to the control module 5. After receiving this instruction, the control module 5 will quickly determine the device priorities of multiple mobile devices. There are many ways to determine the device priority, such as judging based on factors such as the type of device, user settings, and the time sequence of connection. Assume a situation where the user can set certain specific mobile devices to high priority in the settings, such as a tablet computer for work may be set to a higher priority, while a mobile phone for personal entertainment may have a relatively low priority. Alternatively, if a mobile device is the first to be connected to the portable 5GHDMI Dongle device, it can also be given a certain priority advantage. After the priority is determined, the control module 5 determines the mobile device with the highest device priority as the first communication device. At this time, the first communication device has the right to use the device first to display the information to be displayed.

[0043] In some cases, it is assumed that during the use of the device by the first communication device, the second communication device sends the information to be displayed to the communication module 3 more times than the number threshold. This number threshold can be set according to actual needs, such as setting it to send five requests for information to be displayed within a certain period of time. When this happens, the control module 5 will take further action. The control module 5 will send a prompt to the first communication device whether to allow the replacement of the information to be displayed. This prompt can appear on the screen of the first communication device in the form of a pop-up window, allowing the user to intuitively understand the current situation and make a decision. For example, when a user is using a tablet computer (first communication device) to display a work document on a large screen through a portable 5GHDMI Dongle device, at this time, the user's mobile phone (second communication device) continuously sends information to be displayed to the communication module 3 because there is an urgent message to be displayed, and the number of times exceeds the number threshold. The control module 5 will send a prompt to the tablet computer, asking the user whether to allow the replacement of the information to be displayed. If the feedback information that the first communication device allows the replacement is received, the control module 5 will immediately control the display device to display the information to be displayed sent by the second communication device. Such a mechanism not only ensures the priority use right of the first communication device under normal circumstances, but also enables flexible adjustment according to actual needs under special circumstances, thereby improving the use efficiency and flexibility of the device.

[0044] In some embodiments, the portable 5G HDMI Dongle device also includes a verification module 18 for identity authentication when connecting the device. The verification module 18 has a built-in fingerprint recognition chip, which is used to collect the user's fingerprint information and match it with the preset fingerprint template stored in the storage module 6. If the match is successful, the connection is allowed, otherwise the connection is refused to achieve identity authentication of the connected device. For example, when the user inserts the portable 5GHDMI Dongle device into the HDMI interface of the display device and is ready to connect with his mobile device, the verification module 18 will automatically trigger the fingerprint recognition process. After the fingerprint recognition chip collects the user's fingerprint information, the fingerprint recognition chip will match it with the preset fingerprint template stored in the storage module 6. The storage module 6 pre-stores the fingerprint templates of authorized users, which are entered during the device setting stage or when used for the first time. If the two match successfully, it means that user A is an authorized user, and the device will allow the connection. At this time, user A can successfully connect his mobile device to the portable 5GHDMI Dongle device for high-definition video transmission or other operations. However, if the fingerprint information fails to match the preset fingerprint template, the device will refuse to connect. This can effectively prevent unauthorized users from using the device containing very private information, protecting the user's privacy and data security.

[0045] In some embodiments, the portable 5G HDMI Dongle device further includes a display prompt module 19, which is connected to the verification module 18 and the control module 5, and is used to display a verification failure prompt message when the verification module 18 fails to verify. The control module 5 is also used to send a failure prompt signal to the display prompt module 19 when receiving a verification failure signal from the verification module 18, and control the display prompt module 19 to display the verification failure prompt message. As mentioned above, the fingerprint recognition chip built into the verification module 18 will collect the user's fingerprint information and match it with the preset fingerprint template stored in the storage module 6. If the match is successful, the user can smoothly connect the device and perform various operations. However, if the match fails, the verification module 18 will send a verification failure signal to the control module 5. After receiving the verification failure signal from the verification module 18, the control module 5 will take action immediately. It will send a failure prompt signal to the display prompt module 19 to control the display prompt module 19 to display the verification failure prompt message. This process is fast and efficient, ensuring that the user can understand the result of the connection in a timely manner.

[0046] In some embodiments, a counting module 20 is provided between the verification module 18 and the control module 5 in the portable 5G HDMI Dongle device, and the counting module 20 is used to record the number of verification failures and send the number of verification failures to the control module 5; the control module 5 is also used to determine whether the number of verification failures exceeds the preset number threshold. If the number of verification failures exceeds the preset number threshold, the device is locked for a preset time before verification can be performed again. The main function of the counting module 20 is to record the number of verification failures. When the user tries to connect the device, if the verification module 18 determines that the fingerprint information does not match the preset fingerprint template, the verification failure signal will trigger the counting module 20 to count. The counting module 20 will send the recorded number of verification failures to the control module 5. After receiving this number information, the control module 5 will perform further judgment processing. The control module 5 will compare the received number of verification failures with the preset number threshold. The preset number threshold is a value set according to actual needs and security considerations. For example, the preset number threshold can be set to 5 times. If the number of verification failures exceeds the preset number threshold, the control module 5 will lock the device for a preset time before verification can be performed again. This prevents malicious users from trying to crack the device's authentication system. Without such restrictions, malicious users may continue to try different fingerprints or use other improper means to obtain connection permissions, posing a serious threat to the security of the device.

[0047] In some embodiments, the portable 5G HDMI Dongle device further includes an antenna storage component 21 for storing the antenna 7, and the antenna storage component 21 includes an antenna box 22, which is provided with a cavity for accommodating the antenna 7; an antenna folding mechanism 23, which is used to drive the antenna 7 to be retracted and folded; and an elastic buckle mechanism, which is used to realize the automatic pop-up and buckle fixation of the antenna 7. The antenna box 22 is the basic structure of the antenna storage component 21. It is provided with a cavity for accommodating the antenna 7, providing a safe storage space for the antenna 7, which can be set at the bottom of the device. When the antenna 7 is not needed, the antenna 7 can be neatly stored in the antenna box 22 to prevent the antenna 7 from being damaged by external collisions, scratches, etc. The antenna folding mechanism 23 plays a key role in the process of retracting and folding the antenna 7. This mechanism can drive the antenna 7 to unfold or fold according to the needs of the user. When the antenna 7 needs to be used to obtain better signal reception, the antenna folding mechanism 23 can smoothly push the antenna 7 out of the antenna box 22 and unfold it to a suitable angle. The elastic buckle mechanism provides the functions of automatic pop-up and buckle fixation for the use of the antenna 7. When the user needs to use the antenna 7, the elastic buckle mechanism can realize the automatic pop-up of the antenna 7. For example, the user only needs to press a button or trigger a switch, and the elastic buckle mechanism will release the antenna 7, so that it pops out of the antenna box 22, which is convenient for the user to use quickly. When the antenna 7 is used, the user can gently push the antenna 7 back into the antenna box 22, and the elastic buckle mechanism will automatically buckle the antenna 7 in a suitable position to ensure that the antenna 7 will not pop out accidentally in the storage state, thereby realizing the effective storage and convenient use of the antenna 7.
