For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] With the development of electronic equipment technology, the functions of electronic equipment are becoming more and more abundant. At the same time, the types of components used to realize these functions have also increased, or the size has increased, which occupies the space inside the electronic equipment, is not conducive to the overall layout of the electronic equipment, and also hinders the miniaturization of electronic equipment. For example, with the development of technology and the improvement of the functionality of electronic equipment, the use scenarios of electronic equipment in users' daily work and life are becoming more and more extensive. In order to adapt to more use scenarios, electronic equipment has developed wireless charging functions.
[0031] like Figure 1 The figure shows a schematic diagram of the principle of wireless charging of electronic devices. A coil needs to be set in each of the electronic device and the wireless charging device. When the electronic device is charged by the wireless charging device, the coil in the wireless charging device acts as a transmitting coil, and the coil in the electronic device acts as a receiving coil. When the transmitting coil in the wireless charging device is powered on, the transmitting coil will generate alternating current. At this time, if the electronic device is brought close to the wireless charging device, the receiving coil in the electronic device will be electromagnetically coupled with the transmitting coil in the wireless charging device and start to work, converting electromagnetic energy into electrical energy, and then converting the alternating current into direct current through the rectifier circuit and transmitting it to the battery for energy storage, so as to complete the charging of the electronic device.
[0032] According to the wireless charging principle as described above, in order to realize the wireless charging function of an electronic device, it is necessary to add a receiving coil inside the electronic device to generate electromagnetic induction with the transmitting coil in the wireless charging device. Although this method of adding a coil to realize wireless charging improves the functionality of the electronic device, it is not suitable for the current development trend of electronic devices becoming lighter and smaller, and affects the overall layout of the electronic device.
[0033] Based on the above reasons, the present application provides an electronic device. Through the electronic device provided by the embodiment of the present application, the wireless charging function of the electronic device can be realized while ensuring the miniaturization of the electronic device, and the practicality is high.
[0034] It should be noted that the electronic device described in the embodiment of the present application may include at least one of a mobile phone, a tablet computer, and a wearable device, and the embodiment of the present application may not limit the specific type of the electronic device.
[0035] The electronic device provided in the embodiment of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0036] In the embodiment of the present application, the first direction is the thickness direction of the electronic device, the second direction is the length direction of the electronic device, and the third direction is the width direction of the electronic device.
[0037] like Figures 5 to 7 As shown, the electronic device 100 may include: a camera module 1, used to realize the camera function of the electronic device 100, including a motor 10 and a lens assembly 20, the lens assembly 20 is used to converge light, the motor 10 includes a magnetic part 11 and a coil 12, the magnetic part 11 is connected to the lens assembly 20, the coil 12 generates electromagnetic induction with the magnetic part 11 when powered on, and drives the magnetic part 11 to move to drive the lens assembly 20 to move, thereby realizing the focus or anti-shake of the camera module 1; wherein the coil 12 is also used to electromagnetically couple with the first external coil 201 to generate an induced current; a battery 2, used to power the electronic device 100; a first charging circuit 3, including two ends set in opposite directions, one end of which is connected to the coil 12, and the other end is connected to the battery 2, so as to transmit the induced current to the battery 2.
[0038] In the embodiment of the present application, the motor 10 in the camera module 1 is provided with a coil 12 to generate electromagnetic induction with the magnetic part 11 to drive the lens assembly 20 to move, thereby realizing the focus or anti-shake function of the camera module 1. At the same time, the embodiment of the present application further provides a first charging circuit 3 to connect the coil 12 and the battery 2, and reuses the coil 12 in the motor 10. By reusing the coil 12 in the motor 10, it is electromagnetically coupled with the first external coil 201 of the wireless charging device 200, and current can be generated. The current is transmitted to the battery 2 through the charging circuit to charge the battery 2, thereby realizing the wireless charging function of the electronic device 100. The embodiment of the present application realizes the wireless charging function of the electronic device 100 by reusing the coil 12 in the motor 10, that is, the electronic device 100 does not need to be separately provided with a receiving coil for wireless charging, which saves the internal space of the electronic device 100, and is conducive to the overall layout and miniaturization of the electronic device 100.
[0039] In specific applications, such as Figure 8 As shown, the electronic device 100 provided in the embodiment of the present application is placed on the wireless charging device 200, and the coil 12 is opposite to the first external coil 201 of the wireless charging device 200, and the two coils generate current through electromagnetic coupling to charge the electronic device 100.
[0040] In practical applications, multiple camera modules 1 may exist simultaneously in the electronic device 100, including but not limited to a wide-angle camera module 1, a telephoto camera module 1, a periscope camera module 1, a macro camera module 1, etc., wherein each individual camera module 1 is provided with a coil 12 and a magnetic member 11 that interact to drive the lens assembly 20 therein to move, so as to achieve a corresponding shooting function. The camera module 1 in the embodiment of the present application may be the coil 12 in the motor 10 of any camera module 1 in the above examples, and the present application may not make specific limitations on this.
[0041] It should be noted that, generally, the size of the coil 12 in the motor 10 of the periscope camera module 1 is 5mm-8mm, which can meet the 5W charging power of the electronic device 100. Therefore, the electronic device 100 described in the embodiment of the present application has a wide range of uses and high practicality. In addition, since the frequency of the current generated by the mutual coupling of the two coils is related to the size of the coil 12, in order to further improve the efficiency of wireless charging, it can also be achieved by increasing the size of the coil 12.
[0042] Furthermore, when the electronic device 100 includes multiple camera modules 1 , the coils 12 in the motors 10 of the multiple camera modules 1 can be connected in parallel to improve the charging efficiency of the battery 2 .
[0043] Specifically, multiple coils 12 are connected in parallel through the first charging circuit 3 to electromagnetically couple with the first external coil 201 and generate current respectively. Finally, the current is collected by the first charging circuit 3 and transmitted to the battery 2 for storage. In this way, each coil 12 participates in the wireless charging process, further improving the charging efficiency of the electronic device 100.
[0044] Optionally, the electronic device 100 also includes a display screen 5 and a back cover 4 spaced apart along a first direction z, the back cover 4 is provided with a camera opening 41 for light entry, the motor 10 is arranged between the display screen 5 and the back cover 4, and the coil 12 is arranged on a side of the motor 10 close to the back cover 4 to reduce the distance between the coil 12 and the first external coil 201 and improve the charging efficiency.
[0045] In an embodiment of the present application, the electronic device 100 also includes a frame, wherein the frame may include a first side and a second side arranged in opposite directions along a first direction z, the display screen 5 and the back cover 4 are respectively connected to the first side and the second side, and are enclosed with the frame to form a cavity, and the cavity is used to set various components in the electronic device 100. In addition, the frame and the back cover 4 can also be an integrally molded structure, the camera module 1 is located in the cavity, the motor 10 is located in the camera module 1, and is arranged close to the back cover 4.
[0046] In practical applications, when the receiving coil and the transmitting coil in the wireless charging system are closer, the electromagnetic coupling between the two coils is tighter, and the charging efficiency is higher. By arranging the coil 12 close to the back cover 4, it is conducive to more efficient electromagnetic coupling with the first external coil 201, thereby enhancing the generation and transmission efficiency of the induced current.
[0047] It should be noted that the display screen 5, as a visual communication and information interaction component, is not only used to display various information of the electronic device 100, but also for the user to touch and click to achieve information interaction. During the use of the electronic device 100, the user's face needs to face the display screen 5, and the back cover 4 is located on the side of the electronic device 100 away from the user's face, so it is usually used to contact with the external wireless charging device 200 for wireless charging, so that the wireless charging of the electronic device 100 can be achieved without affecting the user and affecting the use of the electronic device 100. Therefore, the embodiment of the present application sets the motor 10 on the side close to the back cover 4 to reduce the distance from the transmitting coil in the wireless charging device 200 and improve the charging efficiency.
[0048] Optionally, the magnetic member 11 and the coil 12 are arranged opposite to each other along the first direction z, and the coil 12 is directly opposite to the first external coil 201 in the wireless charging device 200 to ensure the wireless charging effect.
[0049] like Figures 2 to 4 As shown in FIG. 1 , a common camera module 1 structure of a current electronic device 100 is shown, wherein the coil 12 and the magnetic member 11 are usually arranged in a second direction x and / or a third direction y at intervals to drive the lens assembly 20 to move to realize the function of the camera module 1. In the embodiment of the present application, as shown in FIG. Figures 5 to 7 As shown, the magnetic member 11 and the coil 12 are arranged opposite to each other along a first direction z (the thickness direction of the electronic device 100 ).
[0050] Specifically, Fig. 9 , Fig.10 As shown, it is a schematic diagram of the structure of a coil 12 in an embodiment of the present application. Fig.11 , Fig.12 As shown in FIG. 1 , a schematic diagram of the connection between a magnetic member 11 and a lens assembly 20 in an embodiment of the present application is shown. Figure 6 As can be seen from the side view shown, the coil 12 is located at the top of the motor 10, and correspondingly, the magnetic member 11 is located at the top of the lens assembly 20, and the coil 12 and the magnetic member 11 are arranged opposite to each other along the first direction z; Figure 5 The coil 12 plane of the coil 12 can be seen in the top view shown, and the magnetic part 11 is located at the bottom of the coil 12. In actual application, the magnetic part 11 and the coil 12 perform electromagnetic induction to drive the lens assembly 20 to move, so as to realize the shooting function of the camera module 1.
[0051] It should be noted that the coil 12 acts as a driving member to interact with the magnetic member 11 to drive the lens assembly 20 to move, and acts as a receiving coil to interact with the first external coil 201 to generate current to charge the battery 2. The coil 12 needs to achieve two functions. The size of the coil 12 affects the charging efficiency and also affects the electromagnetic induction between the coil 12 and the magnetic member 11. The distance between the coil 12 and the magnetic member 11 also affects the electromagnetic induction between the coil 12 and the magnetic member 11. Therefore, the size of the coil 12, the size of the magnetic member 11, and the distance between the coil 12 and the magnetic member 11 need to be comprehensively considered to meet both the shooting requirements and the charging requirements. In actual applications, the above parameters can be flexibly designed by technicians according to the actual needs of the electronic device 100, and this application does not make specific restrictions on this.
[0052] In the present application embodiment, Fig. 9 As shown, the coil 12 has a coil 12 plane, and the coil 12 plane is arranged parallel to the back cover 4 to increase the induction area between the first external coil 201.
[0053] It should be noted that if Figure 1 As shown, when the coil 12 in the camera module 1 is arranged in parallel with the first external coil 201, the direction of the current passing therethrough is consistent, and the magnetic flux generated between the two coils extends in a direction perpendicular to the plane of the coil 12, which is beneficial to reduce energy loss during transmission and increase the magnetic flux passing through the two coils, thereby maximizing the charging efficiency.
[0054] Optionally, the motor 10 has a accommodating cavity 130 , which includes a first cavity wall 131 and a second cavity wall 132 arranged opposite to each other along a first direction z, the first cavity wall 131 is arranged close to the back cover 4 , and the coil 12 is arranged in the accommodating cavity 130 and connected to the first cavity wall 131 .
[0055] Specifically, Figure 5 , Figure 6 As shown, the motor 10 in the embodiment of the present application has a housing 13, a receiving cavity 130 is formed in the housing 13, and the housing 13 has two plates arranged opposite to each other along a first direction z, such as Figure 7As shown, it is a schematic diagram of the connection between the camera module 1 and the back cover 4. It can be seen from the figure that among the two plates arranged along the first direction z of the motor 10, one of the plates is arranged close to the back cover 4, and a first cavity wall 131 is formed on its inner wall, and the inner wall of the other plate forms a second cavity wall 132. Among them, since the first cavity wall 131 is the component closest to the back cover 4 in the motor 10, connecting the coil 12 to the first cavity wall 131 can ensure that the distance between the coil 12 and the back cover 4 is minimized. When the back cover 4 contacts the external charging device, the distance between the coil 12 and the transmitting coil in the charging device can be kept at a minimum distance, thereby improving the charging efficiency of the electronic device 100.
[0056] In practical applications, the connection method between the coil 12 and the first cavity wall 131 may include but is not limited to adhesive connection and welding connection, and technicians can choose according to actual needs.
[0057] In the embodiment of the present application, the motor 10 has a accommodating cavity 130, the lens assembly 20 is arranged in the accommodating cavity 130, the lens assembly 20 is provided with a mounting portion 212, the mounting portion 212 and the coil 12 are arranged relative to each other along a first direction z, the magnetic part 11 is connected to the mounting portion 212, and the first direction z is the thickness direction of the electronic device 100.
[0058] like Figure 5 , Figure 6 As shown, the lens assembly 20 is arranged in the accommodating cavity 130 of the motor 10, and is arranged relative to the coil 12 along the first direction z. The magnetic part 11 is connected to the lens assembly 20 and is relative to the coil 12 along the first direction z, so as to ensure electromagnetic induction with the energized coil 12 and be driven to move, thereby driving the lens assembly 20 connected to the magnetic part 11 to move, and realizing the shooting function of the camera module 1. Among them, since the mounting portion 212 and the coil 12 are arranged relative to each other along the first direction, the relative position between the magnetic part 11 and the coil 12 of the lens assembly 20 in a static state is guaranteed, thereby ensuring the effective action between the coil 12 and the magnetic part 11 and the driving reliability and accuracy. In actual applications, the connection method between the magnetic part 11 and the lens assembly 20 may include but is not limited to adhesive connection and welding connection, and the technicians can choose according to actual needs.
[0059] Optionally, the mounting portion 212 is a mounting groove 2121, the lens assembly 20 includes a lens barrel 21, the lens barrel 21 includes a first surface 211 arranged opposite to the coil 12 along the first direction z, the mounting groove 2121 is arranged on the first surface 211, and the magnetic member 11 is embedded in the mounting groove 2121 to improve the connection strength between the magnetic member 11 and the lens assembly 20 and ensure driving reliability. The lens assembly 20 also includes a lens 22, which is connected to the lens barrel 21 and is used to converge light.
[0060] like Figure 6As shown, the first surface 211 is an outer surface opposite to the coil 12, and the mounting portion 212 is a mounting groove 2121 recessed in the first surface 211. Fig.11 and Fig.12 As shown, the dimensions of the mounting groove 2121 along the first direction z and the second direction x are matched with the dimensions of the magnetic component 11, wherein the matching referred to here means that it can be ensured that the magnetic component 11 can be embedded in the mounting groove 2121. In this way, the connection strength and connection effect between the magnetic component 11 and the lens barrel 21 are guaranteed from the mechanical structure. In addition, in order to further improve the connection strength between the two, glue can be dispensed in the mounting groove 2121 between the embedded magnetic components 11. The glue can be used as a connecting medium between the two to enhance the connection effect.
[0061] The electronic device 100 also includes a mainboard, the camera module 1 also includes a first circuit board 30, and the first charging circuit 3 is arranged on the mainboard, or the first circuit board 30. The above settings can realize the function of multiplexing the coil 12 of the camera module in the embodiment of the present application to wirelessly charge the electronic device 100.
[0062] Specifically, the first charging circuit 3 is a rectifier circuit to convert the alternating current generated by the coil 12 into direct current adapted to the battery 2. Fig.13 As shown, it is a schematic diagram of a first charging circuit 3 designed in the embodiment of the present application. In the figure, two capacitors c2 and c3, and two diodes D1 and D2 are added to the first charging circuit 3. It should be noted that since the principle of wireless charging is to use electromagnetic waves to transmit in the air, it may be affected by environmental factors or factors such as the distance between devices during the transmission process, resulting in unstable output current and voltage, which is easy to affect the charger and the device. Therefore, by adding capacitors, smooth output current and voltage can be achieved, and the efficiency and safety of power transmission can be improved. The increase in the number of capacitors will further improve the charging efficiency and the safety of the equipment. The setting of the diode can protect the circuit to avoid damage to the circuit or device due to reverse voltage or excessive peak value. At the same time, since the coil 12 is also a part of the camera module 1 and a part of the wireless charging system, it undertakes two tasks, and the addition of a diode can also control the on and off of the current to achieve efficient energy transmission. By quickly switching the current, energy loss can be reduced and charging efficiency can be improved.
[0063] In addition, if Figures 5 and 6As shown, it is a structural schematic diagram of a periscope camera module 1, which also includes a chip 40, a filter 50, a supporting bracket 60, a prism 70, a ball 80 and other structures, wherein the first circuit board 30 is used to supply power to the chip 40 and the motor 10, the chip 40 is used to realize the imaging of the camera module 1, the filter 50 is used to filter invisible light to prevent the invisible light from affecting the imaging of the chip 40, the supporting bracket 60 is a structural member supporting the filter 50 and the motor 10, the prism 70 is used to reflect light, and the ball 80 is installed in the ball groove 213 to support the movement of the lens assembly 20 during the movement of the lens assembly 20 and the magnetic member 11.
[0064] Optionally, the electronic device 100 also includes a second charging circuit, which is connected between the coil 12 and the battery 2, and is used to receive the voltage of the battery 2 to power the coil 12; when the coil 12 receives the voltage of the battery 2, it is also used to electromagnetically couple with the second external coil 12 to achieve reverse charging.
[0065] It should be noted that reverse charging refers to charging an external electronic device 100 to be charged by the electronic device 100 provided in the embodiment of the present application, and the second charging circuit is a circuit added to realize the reverse charging function of the electronic device 100. Among them, when the battery 2 of the electronic device 100 is fully charged, other electronic devices 100 with lower external power are brought close to the electronic device 100 provided in the embodiment of the present application. At this time, the voltage of the battery 2 can be transmitted to the coil 12 through the second charging circuit, and the coil 12 is electromagnetically coupled with the coil 12 inside the electronic device 100 to be charged to generate current, so as to reversely charge the external electronic device 100 to be charged, thereby enhancing the functionality of the electronic device 100 in the embodiment of the present application and greatly improving the user experience.
[0066] In summary, the electronic device provided by the embodiments of the present application may at least have the following advantages:
[0067] In the embodiment of the present application, the motor in the camera module is provided with a coil to generate electromagnetic induction with the magnetic part to drive the movement of the lens assembly to realize the focus or anti-shake function of the camera module.

By reusing the coil in the motor, it is electromagnetically coupled with the first external coil to generate current, and the current is transmitted to the battery through the first charging circuit to charge the battery, thereby realizing the wireless charging function of the electronic device. The embodiment of the present application realizes the wireless charging function of the electronic device by reusing the coil in the motor, that is, there is no need to set up a separate receiving coil for wireless charging inside the electronic device, which saves the internal space of the electronic device and is conducive to the overall layout and miniaturization of the electronic device.
