[0039] To make the objectives, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0040] Below, in conjunction with Figures 1 - 5 Describe the electronic device component of this application.

[0041] According to an embodiment of this application, with reference to Figure 1 , Figure 2 and Figure 3As shown, an electronic device component is provided, including: a protective cover 100, which forms a receiving cavity 110, an observation window 120 and a projection window 130 communicating with the receiving cavity 110, and the area of the observation window 120 is larger than that of the projection window 130; an electronic device 200, which is disposed in the receiving cavity 110, and the display screen 210 of the electronic device 200 is disposed opposite to the observation window 120; a projection component 300, which is installed in the receiving cavity 110, the projection component 300 is disposed corresponding to the projection window 130, and the projection component 300 is configured to project light through the projection window 130; a first battery 400, which is installed in the protective cover 100, and a second battery 500, which is electrically connected to the projection component 300 to supply power to the projection component 300, and the first battery 400 is configured to be electrically connected to the second battery 500 to charge the second battery 500, and the electronic device 200 is configured to be electrically connected to the second battery 500 to charge the second battery 500.

[0042] It can be understood that in this embodiment, the protective cover 100 forms a receiving cavity 110 for receiving and protecting the electronic device 200. At the same time, the protective cover 100 is provided with an observation window 120 and a projection window 130, and both of these windows communicate with the receiving cavity 110. The observation window 120 allows the user to directly view the display screen 210 of the electronic device 200 without opening the protective cover 100. The projection window 130 corresponds to the projection component 300 to assist in the realization of the corresponding function of the projection component 300. The area of the observation window 120 is larger than that of the projection window 130, which is convenient for the user to observe the display screen 210 of the electronic device 200 from the observation window 120.

[0043] The electronic device 200 is disposed in the receiving cavity 110 of the protective cover 100, and its display screen 210 is disposed opposite to the observation window 120 of the protective cover 100 to ensure that the user can clearly see the content of the display screen 210. In addition, the electronic device 200 is also capable of being electrically connected to the projection component 300 to charge the second battery 500 of the projection component 300 when needed. The projection component 300 is installed in the receiving cavity 110 of the protective cover 100 and is disposed corresponding to the projection window 130. The projection component 300 is electrically connected to the second battery 500, and the power is provided by the second battery 500 for projection through the window of the projection window 130.

[0044] The electronic device component of this embodiment includes two independent batteries: the first battery 400 and the second battery 500. The first battery 400 is installed in the protective case 100, while the second battery 500 is electrically connected to the projection component 300 to provide power for the projection component 300. At the same time, the first battery 400 is configured to be electrically connected to the second battery 500 to charge the second battery 500 when needed. In addition, the electronic device 200 is also configured to be electrically connected to the second battery 500, so that the electronic device 200 can charge the second battery 500. Through the dual charging method configuration, the continuous power supply ability of the projection component 300 is ensured, and the situation of affecting the use experience due to insufficient power is avoided.

[0045] In an alternative embodiment, the projection component 300 is detachably installed on the protective case 100, allowing the user to quickly replace or add the projection component 300 according to actual needs without replacing the entire electronic device 200, improving the flexibility and scalability of the device. Moreover, the user can select the required projection component 300 to carry according to different scenarios, reducing the weight and volume of the overall device, facilitating carrying and storage. When a certain projection component 300 fails, the user can easily disassemble and replace it, reducing the maintenance cost and time.

[0046] The projection component 300 can project the display content of the electronic device 200 onto an external screen or hand, providing a clearer and more convenient viewing experience for the user.

[0047] The electronic device component provided by this application, the protective case 100 provides comprehensive protection for the electronic device 200 to ensure that the device is protected from external damage. It also expands the projection component 300. By integrating the projection component 300, the electronic device component has a projection function to meet the different needs of users. For example, the projection component 300 can be integrated into the protective case 100, and the user can perform projection operations anytime and anywhere without carrying an additional projector device. At the same time, due to the existence of the observation window 120, the user can still normally use the display screen 210 of the electronic device 200 when using the projection function. That is to say, the user can enjoy a richer and more convenient interaction experience when using the electronic device 200. In addition, the protective case 100 and the projection component 300 are provided with independent batteries. The first battery 400 of the protective case 100 can charge the second battery 500, and the electronic device 200 can also charge the second battery 500. The dual charging method of the second battery 500 ensures the battery life and charging flexibility of the projection component 300, providing a convenient charging method and a rich interaction experience.

[0048] According to an embodiment of this application, refer to Figure 1 、 Figure 2 and Figure 4As shown, the electronic device 200 is provided with a first charging coil 220, and the protective cover 100 is further provided with a second coil 510. The second battery 500 is electrically connected to the second charging coil 510. When the electronic device 200 is installed in the accommodation cavity 110, the first charging coil 220 is adapted to be coupled with the second charging coil 510 to charge the second battery 500 through the second charging coil 510.

[0049] It can be understood that in this embodiment, when the electronic device 200 is installed in the accommodation cavity 110 of the protective cover 100, the first charging coil 220 can be close to and coupled with the second charging coil 510. Based on the principle of electromagnetic induction, electrical energy can be transmitted from the first charging coil 220 to the second charging coil 510. The electrical energy received through the second charging coil 510 is then used to charge the second battery 500 to provide electrical energy for the operation of the projection assembly 300. This process is wireless and does not require any physical connection, providing a convenient and flexible way.

[0050] In an alternative embodiment, the first battery 400 and the second battery 500 are connected through a first charging circuit 440. The first battery 400 can charge the second battery 500 through the first charging circuit 440, and the charging between the first battery 400 and the second battery 500 is wired charging. Compared with wireless charging, wired charging usually has a higher charging efficiency and can charge the second battery 500 faster. Moreover, the wired charging method reduces the charging efficiency fluctuations caused by magnetic field interference, distance, and alignment problems, providing a more stable charging environment.

[0051] In an alternative embodiment, the second battery 500 is connected to a second charging circuit 520. The second charging circuit 520 is electrically connected to the first battery 400 and the second charging coil 510, and the second battery 500 can be charged through the first battery 400 or the second charging coil 510.

[0052] According to an embodiment of the present application, referring to Figure 1 、 Figure 2 and Figure 4 As shown, the protective cover 100 is further provided with a third charging coil 410. The third charging coil 410 surrounds the outside of the second charging coil 510 and is spaced apart from the second charging coil 510. The first battery 400 is electrically connected to the third charging coil 410. When the electronic device 200 is installed in the accommodation cavity 110, the third charging coil 410 is adapted to be coupled with the first charging coil 220 to charge the electronic device 200.

[0053] It can be understood that in this embodiment, the first battery 400 in the protective case 100 is connected to a third charging coil 410. The third charging coil 410 is installed at an appropriate position in the protective case 100. When the electronic device 200 is installed in the accommodation cavity 110, this third charging coil 410 can be coupled with the first charging coil 220 on the electronic device 200, thereby realizing wireless charging for the electronic device 200.

[0054] In this embodiment, in addition to charging the second battery 500, the first battery 400 installed on the protective case 100 can also charge the electronic device 200 to ensure that the electronic device 200 also has sufficient battery life.

[0055] According to an embodiment of the present application, with reference to Figure 1 and Figure 4 As shown, the third charging coil 410 surrounds the outside of the second charging coil 510 and is spaced from the second charging coil 510. In this way, when the electronic device 200 is installed on the protective case 100, the first charging coil 220 on the protective case 100 can be close to the second charging coil 510 and the third charging coil 410 at the same time, and the charging relationship between the first battery 400, the second battery 500 and the electronic device 200 can be controlled by controlling the operation of the corresponding charging coils.

[0056] When it is necessary to charge the second battery 500, the charging management system can control the first charging coil 220 to work, obtain power from the electronic device 200 through the principle of electromagnetic induction, and charge the second battery 500; when it is necessary to charge the electronic device 200, the charging management system can control the third coil to work, and provide wireless charging for the electronic device 200 through the principle of electromagnetic induction.

[0057] In some embodiments, the charging management system can set the charging priority according to needs. For example, when the power of the first battery 400 is limited, the electronic device 200 can be charged preferentially to ensure its normal operation; or the second battery 500 can be charged preferentially for emergencies. The charging management system can monitor the battery power and charging status in real time, and turn on or off the corresponding charging coils according to needs. For example, when the second battery 500 is fully charged, the second charging coil 510 can be turned off to save energy; when the electronic device 200 does not need to be charged, the third charging coil 410 can be turned off to reduce electromagnetic radiation.

[0058] According to an embodiment of the present application, with reference to Figure 1As shown, the first charging coil 220 includes a transmitting circuit. The electronic device assembly is further provided with a first power sensor, a first comparison circuit, and a control circuit 420. The first power sensor is configured to detect the first power of the first battery 400 and send the first power to the first comparison circuit. The first comparison circuit is configured to compare the first power with a first preset power, and output a high level to the control circuit 420 when the first power is greater than or equal to the first preset power, and output a low level to the control circuit 420 when the first power is less than the first preset power. The control circuit 420 is configured to control the first battery 400 to charge the second battery 500 when receiving the high level, and control the transmitting circuit to operate when receiving the low level, so that the electronic device 200 charges the second battery 500.

[0059] It can be understood that in this embodiment, the first charging coil 220 includes a transmitting circuit. When the transmitting circuit operates, energy transfer can occur between the first charging coil 220 and the second charging coil 510, enabling the electronic device 200 to charge the second battery 500. Specifically, when charging the second battery 500, the first battery 400 is preferentially used to charge the second battery 500. When the power of the first battery 400 is lower than a certain level, the electronic device 200 charges the second battery 500 to ensure the normal operation of the projection assembly 300.

[0060] When it is necessary to charge the second battery 500, the system continuously detects the power of the first battery 400 through the first power sensor. The first comparison circuit compares the detected power of the first battery 400 with a preset first preset power. When the power of the first battery 400 is greater than or equal to the first preset power, the first comparison circuit outputs a high level to the control circuit 420. When the power of the first battery 400 is less than the first preset power, the first comparison circuit outputs a low level to the control circuit 420.

[0061] When the control circuit 420 receives the high level, it controls the first battery 400 to charge the second battery 500. This is because the power of the first battery 400 is sufficient at this time, and preferentially using the first battery 400 to charge the second battery 500 can ensure the overall efficiency of the system. When the control circuit 420 receives the low level, it controls the transmitting circuit of the first charging coil 220 to operate, enabling the electronic device 200 to charge the second battery 500 through wireless charging. This is because the power of the first battery 400 is already low at this time. To ensure the power supply of other important components, the system chooses to use the remaining power of the electronic device 200 to wirelessly charge the second battery 500, ensuring the continuous operation of the system.

[0062] According to an embodiment of the present application, refer to Figure 1As shown, the first charging coil 220 includes a receiving circuit, and the electronic device assembly is further configured with a second power sensor and a second comparison circuit; the second power sensor is used to detect the second power of the electronic device 200 and send the second power to the second comparison circuit; the second comparison circuit is used to compare the second power with a second power threshold, and when the second power is less than the second power threshold, output a high level to the control circuit 420; the control circuit 420 is used to control the receiving circuit to work when receiving the high level, so that the first battery 400 charges the electronic device 200.

[0063] In this embodiment, when it is detected that the power of the electronic device 200 is lower than a preset value, the electronic device 200 can be charged by the first battery 400. Specifically, the second power sensor continuously detects the second power of the electronic device 200 and sends the second power to the comparison circuit. The comparison circuit sends a control signal to the control circuit 420 based on the relationship between the second power and the second power threshold. After receiving the high-level signal from the comparison circuit, the control circuit 420 activates the receiving circuit, and the third charging coil 410 can charge the electronic device 200 through the receiving circuit, avoiding device shutdown or performance degradation due to insufficient power, extending the battery life of the electronic device 200, and improving the user experience.

[0064] It can be understood that the first power threshold and the second power threshold may be the same or different. In an alternative embodiment, the first power threshold and the second power threshold may be 30% of the full charge. In other embodiments, they may also be other values, which can be designed and adjusted according to specific requirements. This embodiment does not make specific limitations in this regard.

[0065] According to an embodiment of the present application, referring to Figure 1 and Figure 2 As shown, the protective case 100 is provided with an external charging interface 140, and the external charging interface 140 is electrically connected to the first battery 400. The external charging interface 140 is configured to receive an external power source and charge the electronic device 200 and the first battery 400.

[0066] It can be understood that in this embodiment, by providing the external charging interface 140 on the protective case 100, the external charging interface 140 can be configured to receive an external power source and charge the electronic device 200, and the external charging interface 140 can also be configured to receive an external power source and charge the first battery 400. In this way, the first battery 400 and the electronic device 200 can share an external charging interface 140, simplifying the structural design and reducing the occupied volume of the electronic device assembly.

[0067] According to an embodiment of the present application, referring to Figure 1, the second comparison circuit is connected to a Hall switch. The protective cover 100 is provided with an electromagnet 430 arranged corresponding to the Hall switch, and the first battery 400 is connected to the electromagnet 430. The Hall switch is adapted to detect the magnetic field signal of the electromagnet 430, so as to detect the power information of the first battery 400 based on the magnetic field signal of the electromagnet 430.

[0068] It can be understood that in this embodiment, when the first battery 400 has sufficient power, the electromagnet 430 is energized and generates a magnetic field. The Hall switch can detect the presence, absence and strength of the magnetic field signal of the electromagnet 430. The control circuit 420 determines that the first battery 400 has sufficient power by reading the state of the Hall switch. As the first battery 400 is used, its power gradually decreases. When the power is lower than a preset power value, after the electromagnet 430 is powered off, the generated magnetic field disappears. After the control circuit 420 reads the change in the state of the Hall switch, it determines that the first battery 400 has insufficient power. At this time, the control circuit 420 can start the electronic device 200 to charge the second battery 500.

[0069] According to an embodiment of the present application, with reference to Figure 2 As shown, the accommodation cavity 110 is divided into a first space 111 and a second space 112. The first space 111 is adapted to set the electronic device 200, and the projection assembly 300 is configured to be detachably installed in the second space 112, and the first space 111 and the second space 112 are isolated from each other.

[0070] It should be noted that the first space 111 is a dedicated area for setting the electronic device 200 (such as a smart watch, a smart phone, a tablet computer, etc.). The size and shape of the first space 111 are customized according to the size and shape of the target electronic device 200 to ensure that the device can be stably placed therein and is fully protected. The second space 112 is an area for setting the projection assembly 300. Since the projection assembly 300 may include a projection light source, a lens and other auxiliary devices, the second space 112 needs to be large enough to accommodate these components and ensure that they can work properly.

[0071] In the embodiments of the present application, by partitioning the accommodation cavity 110 and separately arranging the electronic device 200 and the projection component 300, the accommodation cavity 110 can be reasonably partitioned, enabling each space area to be fully utilized and improving the overall space utilization rate. Additionally, since the electronic device 200 and the projection component 300 are respectively located in different spaces, their functions are more independent and do not interfere with each other. In some embodiments, the first space 111 and the second space 112 can be isolated from each other. Among them, the two can be separated by a partition (not shown in the figure), etc., and the components located in the first space 111 will not interfere with the components located in the second space 112. In some embodiments, the isolation of the partition can also reduce the risk of fluids (such as water, etc.) or debris entering the second space 112, effectively protecting the components located in the second space 112, such as protecting the projection component 300, etc.

[0072] According to an embodiment of the present application, referring to Figure 2 and Figure 5 as shown, the observation window 120 and the projection window 130 are arranged at intervals, the observation window 120 and the projection window 130 are located on different sides of the protective cover 100, and the light output optical axis direction of the display screen 210 and the light output optical axis direction of the projection component 300 are arranged at an angle.

[0073] It should be noted that the observation window 120 corresponds to the display screen 210, and the projection window 130 corresponds to the projection component 300. Additionally, the display light of the display screen 210 and the projection light of the projection component 300 are not arranged in parallel, and there is a certain angle between them. In this way, the display light of the display screen 210 will not directly irradiate the projection window 130. Similarly, the projection light of the projection component 300 will not interfere with the display effect of the display screen 210. This ensures that users can obtain a clear and interference-free visual experience during use. That is to say, the electronic device 200 and the projection component 300 can work simultaneously.

[0074] In an alternative embodiment, the light output optical axis direction of the display screen 210 and the light output optical axis direction of the projection component 300 are perpendicular to each other.

[0075] It should be noted that the light output optical axis direction of the display screen 210 and the light output optical axis direction of the projection component 300 are arranged perpendicularly. In other words, the front display direction of the display screen 210 and the projection direction of the projection component 300 are perpendicular, forming two independent visual channels.
