Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0054] Combine the following Figures 1 to 7 A protective case for a mobile terminal of the present application is described.

[0055] Reference Figure 1 , Figure 3 as well as Figure 5 The protective shell 100 of the mobile terminal includes a shell 110, a passive driving circuit 120 and a detection sensor 130. The shell 110 includes a main body 111 and a side frame 112 arranged around the main body 111. The main body 111 and the side frame 112 are jointly arranged to form a mounting groove 113. The mounting groove 113 is used for the installation of the mobile terminal. The passive driving circuit 120 is installed on the shell 110. The passive driving circuit 120 is used to wirelessly draw power from the mobile terminal. The detection sensor 130 is installed on the main body 111 and / or the side frame 112. The detection sensor 130 is electrically connected to the passive driving circuit 120 and is powered by the passive driving circuit 120.

[0056] In an embodiment of the utility model, the side frame 112 surrounds the periphery of the main body 111 to form a complete protective structure. This design can prevent the mobile terminal from being damaged by accidental impact, friction or falling during daily use. The design of the mounting slot 113 makes the installation and removal of the protective shell 100 of the mobile terminal very simple and convenient. Using the passive drive circuit 120 and taking power from the mobile terminal wirelessly means that the protective shell 100 of the mobile terminal does not need to be equipped with an independent power supply, which not only reduces the weight, thickness and volume of the protective shell 100 of the mobile terminal, but also avoids the trouble of replacing batteries or charging, providing great convenience for users. Since there is no need for built-in batteries, the safety risks caused by battery aging, short circuit or overheating are reduced. Due to the use of wireless power supply, the protective shell 100 of this mobile terminal can adapt to more types of mobile terminals, without worrying about the problem of being unable to use due to incompatible interfaces or different battery specifications. The detection sensor 130 can detect the state of the target to be detected in real time, which helps to promptly discover and solve problems with the target to be detected. Since the detection sensor 130 is powered by the passive driving circuit 120, no additional power is required, which reduces the complexity of power management and maintenance. By combining the passive driving circuit 120 and the detection sensor 130, the protective case 100 of the mobile terminal can provide users with a more intelligent experience.

[0057] It should be noted that the size and shape of the mounting groove 113 can be customized according to different models and sizes of mobile terminals, so as to ensure that the mobile terminal protective shell 100 can perfectly match various mobile terminals. This highly adaptable design allows users to not worry about the incompatibility of the mobile terminal protective shell 100 with the mobile terminal, and can also provide users with a more fitting and comfortable grip.

[0058] It should be noted that, in the embodiments of the present application, the detection sensor 130 is used to detect human body parameters. Specifically, there are many types of detection sensors 130. The detection sensor 130 may include a heart rate sensor, a body temperature sensor, a blood pressure sensor, an electromyography sensor, a heat flux sensor, a pulse wave sensor, a bioelectric sensor, etc. Specifically, the present application does not limit the type of the detection sensor 130.

[0059] Reference Figures 1 to 4In one embodiment, the side frame 112 is provided with a first side facing the mounting groove 113, and the first side is provided with a first receiving groove 140, and the detection sensor 130 is installed in the first receiving groove 140. In this way, the detection sensor 130 is placed in the first receiving groove 140, which can effectively protect the detection sensor 130 from direct influence of the external environment. This increases the durability and service life of the detection sensor 130, ensuring that it can work continuously and stably. By providing the first receiving groove 140 on the first side of the side frame 112 to install the sensor, the space utilization inside the protective shell 100 of the mobile terminal can be optimized. In addition, the thickness of the shell 110 can also be reduced. The side frame 112 is provided with a first side facing the mounting groove 113, and the detection sensor 130 is installed in the first receiving groove 140, so that the detection sensor 130 is more concealed after installation, thereby enhancing the overall aesthetics of the protective shell 100 of the mobile terminal.

[0060] Reference Figure 5 and Figure 6 In one embodiment, the side frame 112 has a second side that is disposed away from the mounting groove 113, and a second receiving groove 150 is disposed on the second side. The detection sensor 130 is installed in the second receiving groove 150, so that the detection sensor 130 can be effectively protected from direct influence of the external environment, and the durability and reliability of the detection sensor 130 are enhanced. Since the second side that is disposed away from the mounting groove 113 has sufficient operating space, by disposing the second receiving groove 150 and installing the detection sensor 130 on the second side, the disassembly, assembly and maintenance of the detection sensor 130 are simple, which greatly reduces the maintenance cost and time, and improves the maintainability of the product.

[0061] In one embodiment, the detection sensor 130 includes a light sensor, the side frame 112 is at least partially light-transmissive, the first receiving groove 140 is arranged in the light-transmissive portion of the side frame 112, and the light sensor is installed in the first receiving groove 140. In this way, since the light-transmissive portion of the side frame 112 allows light to pass through, the light sensor can emit light signals outward more directly and efficiently. Similarly, when the light signal encounters the target to be detected and is reflected back, the light-transmissive portion also allows these reflected light signals to smoothly enter the first receiving groove 140 and be received by the light sensor. This unobstructed light path design greatly improves the efficiency of signal transmission. The setting of the light-transmissive portion reduces the attenuation and interference of the light signal during the transmission process, thereby improving the detection accuracy of the light sensor. In addition, since the light sensor is located in the light-transmissive portion of the side frame 112, it can cover a wider detection area. Whether it is a target on the side or in front of the side, as long as it is within the detection range of the light sensor, it can be effectively detected. This design increases the detection range of the light sensor and improves its applicability and flexibility.

[0062] In one embodiment, the detection sensor 130 includes a light sensor, and the second receiving groove 150 is also filled with a light-guiding colloid, and the light-guiding colloid wraps the light sensor. In this way, the light-guiding colloid has excellent light-guiding performance, which can ensure that the light signal emitted by the light sensor is less lost during the transmission process. Similarly, when the light signal is reflected back by the target to be detected, the light-guiding colloid can efficiently guide the reflected light signal into the light sensor, thereby improving the efficiency of signal transmission. The light-guiding colloid can evenly distribute the light signal emitted by the light sensor, ensuring that the light signal can cover a wider detection area. This helps the light sensor to more accurately perceive the parameter information of the target to be detected. Due to the wrapping of the light-guiding colloid, the interference of the light sensor by the external ambient light will be greatly reduced. This helps to ensure that the light sensor only receives the reflected light signal related to the target to be detected, thereby improving the accuracy and reliability of the detection. The light-guiding colloid not only has a light-guiding function, but also provides a layer of protection for the light sensor. It can prevent impurities such as dust and moisture from entering the second receiving groove 150 and affecting the performance of the light sensor. In addition, the light-guiding colloid can also play a buffering role, reducing the damage to the light sensor caused by external impact. By filling the light-guiding colloid to wrap the light sensor, the assembly process can be simplified and the production cost can be reduced. At the same time, the use of the light-guiding colloid can also ensure the position stability of the light sensor during the assembly process, avoiding problems such as positional displacement during subsequent use.

[0063] Reference Figure 2 and Figure 4In one embodiment, the side frame 112 includes a plurality of frame bars 1121 connected in sequence along the circumferential direction, the plurality of frame bars 1121 include a first frame bar 11211 and a second frame bar 11212 arranged relatively to each other, and the first frame bar 11211 and the second frame bar 11212 are both installed with a detection sensor 130, so that when checking the health of the human body, when the left hand or the right hand is held vertically, the detection sensor 130 can check the corresponding target parameter information. By installing the detection sensor 130 on both the first frame bar 11211 and the second frame bar 11212, more comprehensive and accurate target parameter information can be provided. Since the plurality of detection sensors 130 work at the same time, they can complement and verify the data with each other. If a detection sensor 130 generates an error for some reason, the data of other detection sensors 130 can be used as a reference, thereby improving the overall detection accuracy. In addition, the simultaneous detection of multiple detection sensors 130 can also reduce the risk of misjudgment caused by the error of a single detection sensor 130 itself or environmental interference. When holding the protective case 100 of the mobile terminal for inspection, the user's hand posture and position may change. By installing the detection sensor 130 on both the first frame bar 11211 and the second frame bar 11212, the device can better adapt to different hand postures and positions, ensuring that no matter how the user holds the protective case 100 of the mobile terminal, effective detection can be performed. This design improves the user's comfort and convenience and optimizes the user experience.

[0064] Reference Figure 1 , Figure 2 and Figure 6In one embodiment, the side frame 112 includes a plurality of frame bars 1121 connected in sequence along the circumferential direction, the plurality of frame bars 1121 include a first frame bar 11211 and a third frame bar 11213 arranged adjacently, and the first frame bar 11211 and the third frame bar 11213 are both installed with a detection sensor 130, so that when checking the health of the human body, when the left or right hand is held horizontally or vertically, the detection sensor 130 can check the corresponding target parameter information. By installing the detection sensor 130 on both the first frame bar 11211 and the third frame bar 11213, more comprehensive and accurate target parameter information can be provided. Since the plurality of detection sensors 130 work simultaneously, they can complement and verify the data with each other. If an error occurs in a detection sensor 130 for some reason, the data of other detection sensors 130 can be used as a reference, thereby improving the overall detection accuracy. In addition, the simultaneous detection of multiple detection sensors 130 can also reduce the risk of misjudgment caused by the error of a single detection sensor 130 itself or environmental interference. When holding the protective case 100 of the mobile terminal for inspection, the user's hand posture and position may change. By installing the detection sensor 130 on both the first frame bar 11211 and the third frame bar 11213, the protective case 100 of the mobile terminal can better adapt to different hand postures and positions, ensuring that effective detection can be performed no matter how the user holds the device. This design improves the user's comfort and convenience and optimizes the user experience.

[0065] It should be noted that, in other embodiments, referring to Figure 2 and Figure 6 The side frame 112 includes a plurality of frame bars 1121 connected in sequence along the circumference thereof, the plurality of frame bars 1121 include a first frame bar 11211, a second frame bar 11212 and a third frame bar 11213 which are arranged relatively, the first frame bar 11211 and the second frame bar 11212 are arranged relatively, the first frame bar 11211 and the third frame bar 11213 are arranged adjacently, and the first frame bar 11211, the second frame bar 11212 and the third frame bar 11213 are all installed with detection sensors 130, so that all-round detection can be achieved, which is helpful to obtain more comprehensive and detailed target parameter information. The simultaneous operation of multiple detection sensors 130 can complement and verify data with each other. If a detection sensor 130 is disturbed or has errors, the data of other detection sensors 130 can be used as a reference, thereby improving the overall detection accuracy. When the protective shell 100 of the mobile terminal is held by hand for inspection, the user's hand posture and position may change. By installing detection sensors 130 on the frame strips at different positions and angles, the device can better adapt to different holding methods, ensuring that effective detection can be performed regardless of how the user holds the device. This design improves the user's comfort and convenience and optimizes the user experience.

[0066] Reference Figures 1 to 6 In one embodiment, the side frame 112 includes a plurality of frame bars 1121 connected in sequence along the circumference thereof, and at least one frame bar 1121 is installed with a plurality of detection sensors 130. Thus, installing a plurality of detection sensors 130 on a single frame bar 1121 can significantly increase the density of the detection area, thereby more accurately capturing the information of the target to be detected, and improving the accuracy of the detection. The simultaneous operation of a plurality of detection sensors 130 can quickly collect a large amount of data, thereby improving the detection efficiency. When the protective case 100 of the mobile terminal is held by hand, the user's holding posture may change. Installing a plurality of sensors on a single frame bar 1121 can ensure that no matter how the user holds it, there are enough sensors to contact the user's palm or finger, thereby maintaining the effectiveness of the detection. The amount of data that can be collected by the plurality of detection sensors 130 is larger and more comprehensive, and more complex algorithms can be used for data processing and analysis, thereby drawing more accurate conclusions. Installing a plurality of sensors on a single frame bar 1121 can form a redundant design and improve the robustness of the system. Even if one of the sensors fails or is interfered with, the other sensors can still continue to work, ensuring the continuity and accuracy of the detection.

[0067] In one embodiment, the detection sensor 130 includes a light sensor, and the light sensor includes a heart rate sensor and / or a blood oxygen sensor. In this way, light sensors such as heart rate sensors and blood oxygen sensors usually use optical principles for detection, and do not need to be performed through insertion or other invasive methods, making the detection process more comfortable and convenient. The light sensor can monitor the physiological parameters of the human body, such as heart rate and blood oxygen saturation, in real time, which is convenient for continuous monitoring of health status. The light sensor can adapt to different environments and usage conditions. The light sensor is small in size, and integrating the light sensor with the protective case 100 of the mobile terminal reduces the volume and thickness of the protective case 100 of the mobile terminal to a certain extent.

[0068] In one embodiment, a receiving groove is provided on the side of the side frame, and the light sensor includes a light source transmitter and a light source receiver. The light source transmitter is installed in the receiving groove and is electrically connected to the passive driving circuit 120. The light source transmitter is used to emit a light signal. The light source receiver is installed in the receiving groove and is arranged adjacent to the light source transmitter. The light source receiver is electrically connected to the passive driving circuit 120. The light source receiver is used to receive the light signal reflected by the human body. In this way, since the light source transmitter emits a light signal and then the light source receiver receives the light signal reflected back by the human body, the whole process does not need to be performed by insertion or other invasive methods, thereby ensuring the comfort and convenience of the measurement. The light source transmitter can continuously or periodically emit a light signal, and the light source receiver receives the reflected signal in real time. This design enables the light sensor to monitor the state or parameter changes of the target to be detected in real time. The light source transmitter and the receiver can adapt to different environments and conditions of the target to be detected, which enables the light sensor to maintain high performance and stability in various application scenarios. The light source transmitter and the receiver are usually small in size and light in weight, and are integrated into the protective case 100 of the mobile terminal, so that the protective case 100 of the mobile terminal has the detection function and is small, light, and easy to carry.

[0069] Reference Figure 7In one embodiment, the passive driving circuit 120 includes an antenna circuit 121 and a power supply circuit 122. The power supply circuit 122 is connected to the antenna circuit 121 to convert the radio frequency energy emitted by the mobile terminal into electrical energy through the antenna circuit 121; wherein the power supply circuit 122 includes a matching circuit 1221, a rectifier circuit 1222 and an energy storage circuit 1223, the matching circuit 1221 is connected to the antenna circuit 121 and cooperates to output the first electrical energy, the rectifier circuit 1222 is connected to the matching circuit 1221 and rectifies the first electrical energy, the energy storage circuit 1223 is connected to the rectifier circuit 1222 and stores the rectified first electrical energy, the energy storage circuit 1223 is connected to the detection sensor 130 and supplies power to the detection sensor 130, so that the passive driving circuit 120 receives and converts the radio frequency energy from the mobile terminal into electrical energy through the antenna circuit 121, thereby achieving energy self-sufficiency. This reduces the dependence on an external power source or battery, and improves the independence and portability of the protective shell 100 of the mobile terminal. The matching circuit 1221 is connected to the antenna circuit 121 to cooperate in outputting the first electric energy to ensure that the radio frequency energy is effectively converted into electric energy. The rectifier circuit 1222 further rectifies the first electric energy to provide the required electric energy for the energy storage circuit 1223 and the detection sensor 130. The energy storage circuit 1223 is responsible for storing the rectified electric energy to ensure that the detection sensor 130 can still obtain a stable power supply when the radio frequency energy is unstable or interrupted, which improves the stability and reliability of the passive drive circuit 120. The use of the passive drive circuit 120 reduces the use and replacement frequency of batteries, reduces pollution to the environment, and achieves energy conservation and emission reduction.

[0070] It should be noted that the matching circuit 1221 cooperates with the antenna circuit 121 to output an oscillation wave signal, the rectifier circuit 1222 rectifies the oscillation wave signal and outputs a direct current signal, and the energy storage circuit 1223 stores the direct current signal.

[0071] Reference Figure 7In one embodiment, the protective shell 100 of the mobile terminal further includes a communication circuit 160 and a microprocessor 170, the communication circuit 160 is connected to the antenna circuit 121, the microprocessor 170 is connected to the power supply circuit 122 and is powered by the power supply circuit 122, and the microprocessor 170 is connected to the detection sensor 130 and the communication circuit 160 to transmit the information detected by the detection sensor 130 to the mobile terminal, so that the microprocessor 170 can receive the information captured by the detection sensor 130 in real time and transmit the data to the mobile terminal through the communication circuit 160, which ensures the immediacy and accuracy of the data. The introduction of the microprocessor 170 enables the protective shell 100 of the mobile terminal to have data processing and decision-making capabilities. It can perform corresponding operations based on the detected information, or send the information to the mobile terminal for further analysis and processing. This enhances the intelligence level of the protective shell 100 of the mobile terminal, so that it can better adapt to different usage scenarios. Due to the presence of the microprocessor 170 and the communication circuit 160, the protective shell 100 of the mobile terminal can easily connect and communicate with other smart devices or systems. This provides possibilities for future functional expansion and integration. By connecting to the mobile terminal, the user can view and manage the functions and data of the protective case 100 of the mobile terminal through a familiar interface and device. This reduces the user's learning cost and improves ease of use.

[0072] Reference Figure 1 , Figures 5 to 7 In one embodiment, the protective shell 100 of the mobile terminal further includes a display device 180 and a microprocessor 170. The display device 180 is connected to and powered by the power supply circuit 122, the microprocessor 170 is connected to and powered by the power supply circuit 122, the microprocessor 170 is connected to the detection sensor 130 and connected to the display device 180, so that the information detected by the detection sensor 130 is displayed through the display device 180, so that the display device 180 can display the information captured by the detection sensor 130 in real time without the user having to view it through other devices (such as mobile terminals). This greatly increases the convenience of users in obtaining information. Since the information is displayed directly on the display device 180 of the protective shell 100 of the mobile terminal, the user can immediately see the changes and react. The display device 180 and the microprocessor 170 of the protective shell 100 of the mobile terminal give it a certain degree of independence. Even when not connected to the mobile terminal, the protective shell 100 of the mobile terminal can still work normally and display key information. This provides users with more flexibility. By transferring some information display functions to the protective case 100 of the mobile terminal, the processing and display burden of the mobile terminal can be reduced, which helps to improve the performance and response speed of the mobile terminal.

[0073] In some embodiments, the communication circuit 160 includes an NFC chip, and the NFC chip cooperates with the antenna circuit 121 to obtain the second electrical energy. The NFC chip supplies power to the communication circuit 160 through the second electrical energy.

[0074] The NFC chip integrates an energy processing circuit to process the energy provided by the antenna circuit 121 and convert it into a second electrical energy, thereby powering the NFC chip itself. In some examples, the NFC chip can also use the second electrical energy to power other devices, such as the microprocessor 170, so that when the power supply circuit 122 does not power the microprocessor 170 and the communication circuit 160, the microprocessor 170 and the communication circuit 160 can wirelessly communicate with the mobile terminal through the antenna circuit 121 to transmit data.
