[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a protective shell. Background Art

[0002] With the widespread application of electronic devices, the functional requirements for electronic device peripheral products are also constantly increasing. In the relevant technology, functional components can usually be added to the protective shell of the electronic device to meet the diverse needs of users. For example, in order to meet the fill light requirements of the front camera of the electronic device during the shooting process, a fill light group can be set on the protective shell to fill the light for the front camera. However, generally speaking, when the functional components on the protective shell realize their functions, they need power supply based on their own needs, which often affects the normal charging function of the electronic device. Therefore, it is difficult for the existing protective shell to take into account both its functional requirements and the charging requirements of the electronic device. Summary of the invention

[0028] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0029] Based on diverse designs, protective cases for electronic devices in the related art usually have functional components provided on the case body. The functional components may include fill light groups, loudspeakers, additional cameras, etc., and the electronic devices may include mobile phones, tablet computers, cameras, handheld computers, learning machines, e-books, or wearable devices, etc. For the convenience of understanding the technical solutions in the embodiments of the present application, the following may take the electronic device as a mobile phone and the functional component as a fill light group as an example for illustration.

[0030] It can be understood that currently, users have higher and higher requirements for the quality of photos or videos taken by the front camera of mobile phones. One of the key points for improving the quality of photos or videos lies in filling light for the front camera. Based on the fill light requirement of the front camera, a fill light device can be newly added at the position of the front camera of the mobile phone. When the front camera is turned on, the mobile phone drives the fill light to light up to achieve the fill light effect. However, the inventor found that this solution requires adding internal devices to the mobile phone, which affects the stacking area of the printed circuit board, reduces the screen-to-body ratio, and the long-term turning on of the fill light will cause the local temperature at the position of the front camera to be too high, thereby affecting the service life of the mobile phone. A fill light group can also be added to mobile phone accessories. For example, a fill light group and an energy receiving module can be added to the mobile phone protective case. For example, the fill light group is powered by wireless coil coupling energy, or is connected to the mobile phone through a USB interface in a wired manner to power the fill light group, so as to achieve the fill light function. However, the inventor found that this energy supply path will affect the normal charging function of the mobile phone when the mobile phone is wearing a protective case. For example, the presence of the wireless coil will affect the efficiency of wireless charging of the mobile phone, and even cause the mobile phone to be unable to perform wireless charging, while USB power supply will cause the USB port of the mobile phone to be occupied, on the one hand, affecting wired charging, and on the other hand, the wired connection method has redundant wire harnesses, affecting the convenience of using the mobile phone.

[0031] Based on the above technical problems, the embodiments of the present application provide a protective case that can take into account both its own functional requirements and the charging requirements of the electronic device. The following will be combined with Figures 1 to 6 Describe the protective case according to the embodiments of the present application.

[0032] As Figure 1 And Figure 2As shown in the figure, an embodiment of the present application provides a protective case for being sleeved on an electronic device to protect the electronic device. The protective case includes a housing 1, a functional component 2, a wireless coil 3, and a movable component 4. The functional component 2 is movably connected to the housing 1. The wireless coil 3 is disposed inside the housing 1 and is electrically connected to the functional component 2. The movable component 4 is disposed on the housing 1. Both the functional component 2 and the wireless coil 3 are connected to the movable component 4, and the functional component 2 can drive the wireless coil 3 to move through the movable component 4. The functional component has a first state and a second state, where: in the first state, the functional component 2 is disposed on the surface of the housing 1, and the wireless coil 3 moves to a first position. When the electronic device wears the protective case, the wireless coil 3 is staggered from the built-in coil of the electronic device. In the second state, the functional component 2 extends out of the housing 1, and the wireless coil 3 moves to a second position. When the electronic device wears the protective case, the wireless coil 3 at least partially overlaps with the built-in coil.

[0033] In the embodiment of the present application, the functional component 2 can drive the movable component 4 to move, and the wireless coil 3 can move relative to the housing 1 under the drive of the movable component 4, so that the wireless coil 3 can be located at the first position or the second position inside the housing 1. When the electronic device wears the protective case and the functional component 2 is not needed, such as Figure 1 As shown in the figure, the functional component 2 can be disposed on the surface of the housing 1, and the wireless coil 3 can move to the first position. At this time, the wireless coil 3 is staggered from the built-in coil of the electronic device, and the wireless coil 3 cannot be coupled with the built-in coil. Therefore, at this time, the functional component 2 has no power supply and is in an unusable state. At the same time, the position of the wireless coil 3 will not affect the coupling between the built-in coil of the electronic device and the charging coil of the wireless charger. In other words, when the wireless coil 3 is located at the first position, the electronic device can be normally wirelessly charged.

[0034] When the electronic device wears the protective case and the functional component 2 is needed, such as Figure 2 As shown in the figure, the functional component 2 can extend out of the housing 1, and the movable component 4 can move with the movement of the functional component 2, and then can drive the wireless coil 3 to move to the second position. At this time, the wireless coil 3 at least partially overlaps with the built-in coil of the electronic device, and the wireless coil 3 can be coupled with the built-in coil, so that the electronic device can supply power to the functional component 2, and then the function corresponding to the functional component 2 can be realized.

[0035] In this way, the wireless coil 3 and the functional component 2 of the protective shell can be linked through the movable component 4, so that when the electronic device wears the protective shell, when the functional component 2 is in use, the wireless coil 3 can couple with the built-in coil of the electronic device and supply energy to the functional component 2, and when the functional component 2 is not in use, the wireless coil 3 is staggered with the built-in coil of the electronic device to avoid affecting the wireless charging energy supply of the electronic device. That is, the protective shell can take into account both its own functional requirements and the charging requirements of the electronic device.

[0036] Generally speaking, the built-in coil of the electronic device is set in the middle of the electronic device. Accordingly, the first position of the housing 1 can be located at the bottom of the housing 1, and the second position of the housing 1 can be located in the middle of the housing 1. That is, when the functional component 2 is not in use, the wireless coil 3 can be located at the bottom of the housing 1, and when the functional component 2 is in use, the wireless coil 3 can be located in the middle of the housing 1. It can be understood that the first position and the second position are not specifically limited and can be determined according to the position of the built-in coil of the electronic device corresponding to the protective shell.

[0037] Optionally, in some embodiments, the functional component 2 can be slidably connected to the shell 1, wherein one end of the movable component 4 is connected to the functional component 2, and the other end of the movable component 4 is connected to the wireless coil 3, and when the functional component 2 slides from the position of the first state to the position of the second state, the movable component 4 drives the wireless coil 3 to move from the first position to the second position.

[0038] In this embodiment, the functional component 2, the movable component 4 and the wireless coil 3 can all be slidably arranged with the housing 1. When the user uses the functional component 2 and slides the functional component 2 from the first state to the second state, the functional component 2 drives the movable component 4 to slide relative to the housing 1, and then the movable component 4 drives the wireless coil 3 to move from the first position to the second position. In this way, the overall structure of the protective shell is simple, and the various components are coordinated and linked, which can meet a variety of different needs and is more convenient to use.

[0039] Optionally, see Figure 1 and 3 In some embodiments, a groove 11 is provided on the surface of the housing 1, and in the first state, the functional component 2 is stored in the groove 11. When not in use, the functional component 2 can be stored in the groove 11 on the surface of the housing 1, so that the space occupied by the protective case can be reduced, thereby making the electronic device wearing the protective case more compact and easier to use and carry.

[0040] Generally speaking, a hollow portion needs to be formed on the housing 1 of the protective case. When the electronic device is equipped with the protective case, its rear camera can be exposed through the hollow portion. For example, the functional component 2 can be a fill light group. A rectangular hollow portion can be formed on the housing 1. For the flatness and space utilization rate of the housing 1, the fill light group can be rectangular. Correspondingly, a rectangular groove 11 can be formed on the housing 1, and the groove 11 can be arranged around the hollow portion. In other words, the fill light group can be received in the housing 1 along the circumferential direction of the hollow portion. It can be understood that the fill light group can also be circular or any other shape, which can be adjusted according to actual needs and will not be specifically limited here.

[0041] Optionally, in some embodiments, the functional component 2 is rotatably connected to the first side of the housing 1, and the functional component 2 can rotate along the edge of the first side.

[0042] It can be understood that taking the functional component 2 as the fill light group as an example, generally speaking, the camera is arranged at the top of the electronic device. Therefore, the first side of the housing 1 can refer to the top side of the housing 1. The fill light group can be rotatably connected to the first side through a rotating shaft structure. When it is necessary to fill light for the front camera, the fill light group can rotate along the edge of the first side to the front side of the electronic device. After the fill light group is not needed, it can rotate along the edge of the first side to the back side of the electronic device until it is received in the groove 11 of the housing 1.

[0043] In some examples, in order to make the fill light effect of the front camera better, in the second state, the fill light group can rotate along the edge of the first side to the front side of the electronic device until it is in the same plane as the display screen of the electronic device. In other words, in the second state, the fill light group can be fully unfolded relative to the housing 1 to maximize the fill light effect.

[0044] Optionally, please refer to Figure 3 , in some embodiments, the movable component 4 can include a sliding member 41 and a hinge 42; the sliding member 41 is slidably connected to the housing 1, and one end of the sliding member 41 is connected to the wireless coil 3; one end of the hinge 42 is connected to the other end of the sliding member 41, and the other end of the hinge 42 is connected to the functional component 2; wherein, when the functional component 2 rotates along the edge of the first side, the hinge 42 moves with the functional component 2 and drives the sliding member 41 to slide on the housing along a direction perpendicular to the first side, and the sliding member 41 drives the wireless coil 3 to move.

[0045] In this embodiment, the functional component 2 and the wireless coil 3 can be linked through the slider 41 and the hinge 42. When the user rotates the functional component 2 along the edge of the first side of the housing 1, the hinge 42 moves in a direction perpendicular to the first side as the functional component 2 rotates. At this time, one end of the hinge 42 connected to the slider 41 can drive the slider 41 to slide on the housing 1 in a direction perpendicular to the first side, and then the slider 41 drives the wireless coil 3 to move when sliding. For example, when the functional component 2 rotates from the position in the first state to the position in the second state, the hinge 42 approaches the first side as the functional component 2 rotates, drives the slider 41 to slide, and then drives the wireless coil 3 to move from the first position to the second position.

[0046] In this embodiment, through the cooperation of the slider 41 and the hinge 42, the position linkage between the functional component 2 and the wireless coil 3 is realized. When the functional component 2 rotates, it drives the wireless coil 3 to move, which is simpler and more convenient to use while meeting various different requirements.

[0047] Optionally, in some embodiments, the number of the sliders 41 and the hinges 42 is at least two groups.

[0048] It can be understood that at least two groups of sliders 41 can be arranged at intervals on the housing 1, one end of at least two groups of sliders 41 is respectively connected to the wireless coil 3, the other end of at least two groups of sliders 41 is respectively connected to the same number of hinges 42, and the ends of at least two groups of hinges 42 far from the sliders 41 can be respectively connected to the functional component 2.

[0049] As Figure 3 shown, taking the number of the sliders 41 and the hinges 42 being two groups as an example, sliders 41 can be arranged on both sides of the housing 1. Two groups of sliders 41 are respectively connected to both sides of the wireless coil 3, and each group of sliders 41 is connected to a group of hinges 42, and two groups of hinges 42 are respectively connected to both sides of the functional component 2. In this way, the reliability of the position linkage between the functional component 2 and the wireless coil 3 can be effectively ensured. On the one hand, the movement process can be smoother, and on the other hand, the force during the movement can be shared, and thus the service life of the protective case can be extended.

[0050] Optionally, please refer to Figure 3 , in some embodiments, the movable component 4 may further include a coil connecting piece 43. One end of the coil connecting piece 43 is connected to the wireless coil 3, and the other end of the coil connecting piece 43 is connected to the end of the slider 41 far from the hinge 42.

[0051] Generally speaking, there may be a difference between the diameter of the wireless coil 3 and the width of the functional component 2. In actual settings, the positions of the wireless coil 3 and the functional component 2 may not be on the same straight line. At this time, in order to ensure that the process of the functional component 2 driving the slider 41 to slide during rotation is smoother, the hinge 42, the slider 41, and the fulcrum where the functional component 2 drives the hinge 42 to move can be arranged on the same straight line. And in order for the slider 41 to drive the wireless coil 3 to slide smoothly, the wireless coil 3 can be connected to the slider 41 through a coil connecting member 43. The coil connecting member 43 can flexibly adjust the connection position between the slider 41 and the wireless coil 3, thereby improving the applicable range of the movable component 4 while ensuring the reliability of the position linkage between the functional component 2 and the wireless coil 3.

[0052] It can be understood that in some examples, when the number of the sliders 41 and the hinges 42 is two groups, the coil connecting members 43 can be two groups, respectively connected to both sides of the wireless coil 3 and the two groups of sliders 41. The coil connecting member 43 can also be one group, and the coil connecting member 43 can be connected to the wireless coil 3 and the two groups of sliders 41 at the same time, and no specific limitation is made here.

[0053] Optionally, as Figure 4 shown, in some embodiments, a chute 12 is formed on the housing 1, and the slider 41 is slidably arranged in the chute 12. In this way, the slider 41 can slide in the chute 12 without protruding from the housing 1, ensuring the flatness of the housing 1 and further saving the occupied space of the protective case.

[0054] Optionally, please refer to Figure 5 , in some embodiments, a first limiting member 13 and a second limiting member 14 are arranged at intervals at the position of the housing 1 corresponding to the slider 41. A third limiting member 411 is arranged on the slider 41, and the third limiting member 411 can be connected in cooperation with the first limiting member 13 or the second limiting member 14; wherein, when the third limiting member 411 is connected in cooperation with the first limiting member 13, the functional component 2 is in the first state, and when the third limiting member 411 is connected in cooperation with the second limiting member 14, the functional component 2 is in the second state.

[0055] In this embodiment, a third limiting member 411 is provided on the sliding member 41, which can cooperate with the limiting member provided on the housing 1 for limiting. For example, the first limiting member 13 and the second limiting member 14 can be provided on the housing 1 at intervals. When the functional component 2 is not needed, the third limiting member 411 can cooperate with the first limiting member 13 for connection. At this time, the functional component 2 can be fixed in the first state, and the wireless coil 3 is fixed in the first position. When the functional component 2 is needed, the third limiting member 411 can cooperate with the second limiting member 14 for connection. At this time, the functional component 2 can be fixed in the second state, and the wireless coil 3 is fixed in the second position. In this way, the stability after the position switch can be ensured, and the protective case can better meet its own functional requirements and the charging requirements of the electronic device.

[0056] It can be understood that the cooperation connection between the third limiting member 411 and the first limiting member 13 or the second limiting member 14 can be realized by means of snap connection, pasting or magnetic attraction, etc., and no specific limitation is made here.

[0057] Optionally, in some embodiments, the first limiting member 13, the second limiting member 14 and the third limiting member 411 can all be magnets. The cooperation connection between the third limiting member 411 and the first limiting member 13 or the second limiting member 14 can be realized by the attraction force between the magnets. When the position needs to be switched, only an acting force needs to be provided for the functional component 2 to break the original magnetic cooperation connection state, making the operation simpler and more convenient.

[0058] Optionally, please refer to Figure 5 , in some embodiments, the housing 1 is further provided with at least one fourth limiting member 15. The fourth limiting member 15 is located between the first limiting member 13 and the second limiting member 14, and the third limiting member 411 can cooperate with the fourth limiting member 15 for connection; wherein, when the third limiting member 411 cooperates with the fourth limiting member 15 for connection, the functional component 2 is in the third state. In the third state, there is an included angle between the functional component 2 and the housing 1.

[0059] It can be understood that in addition to the first state of being received in the groove 11 of the housing 1 and the second state of completely extending out of the housing 1, the functional component 2 can also include a third hovering state. When the functional component 2 hovers relative to the housing 1, there can be an included angle between the functional component 2 and the housing 1. The hovering degree of the functional component 2 can be controlled by adjusting the size of the included angle.

[0060] In this embodiment, at least one fourth limiting member 15 can be provided between the first limiting member 13 and the second limiting member 14. When the third limiting member 411 is cooperatively connected with the fourth limiting member 15, the functional component 2 can be fixed at the position in the hovering state. For example, when the functional component 2 is a fill light group, the fill light intensity can be flexibly adjusted through the hovering state of the fill light group, thereby meeting different needs of users and improving the applicability of the protective case.

[0061] Optionally, please refer to Figure 1 , Figure 2 and Figure 6 , in some embodiments, the length L1 of the hinge 42 can be greater than or equal to the first distance L2, where the first distance L2 is the distance from the connection position of the hinge 42 and the functional component 2 to the connection position of the functional component 2 and the housing 1. It can be understood that the rotation degree of the functional component 2 is limited by the hinge 42. To ensure that the functional component 2 can completely extend out of the housing 1, that is, the functional component 2 can be parallel to the display screen of the electronic device, the length L1 of the hinge 42 can be greater than or equal to the distance from the connection position of the hinge 42 and the functional component 2 to the connection position of the functional component 2 and the housing 1.

[0062] Optionally, please refer to Figure 1 , Figure 2 and Figure 6 , in some embodiments, the first distance L2 can be equal to half of the second distance L3, where the second distance L3 is the movement distance of the wireless coil 3 from the first position to the second position.

[0063] It can be understood that when the functional component 2 can rotate from being received in the groove 11 of the housing 1 to completely extending out of the housing 1, that is, the rotation angle is 180°, the movement distance of the sliding plate is the distance from the connection positions of the two hinges 42 and the functional component 2 to the connection position of the functional component 2 and the housing 1. Then, to ensure that the wireless coil 3 can move from the first position to the second position, the following condition needs to be met: the distance from the connection position of the hinge 42 and the functional component 2 to the connection position of the functional component 2 and the housing 1 is equal to half of the distance between the first position and the second position.
