[0002] With the continuous expansion of the folding device market, the types of folding devices are also increasing day by day, and more and more consumers are starting to use folding devices. When the folding device is in a folded state, since components such as the folding part and the hinge cover usually directly contact the collision position (such as the ground) during the fall, the relevant components of the electronic device are damaged; when the folding device is in an unfolded state, since the display screen usually directly contacts the collision position during the fall, the display screen of the electronic device is damaged. Therefore, there is a problem that the components of the electronic device are easily damaged in the prior art. Summary of the Invention

[0003] Embodiments of this application provide a protective cover and an electronic device assembly to solve the problem that the components of the electronic device are easily damaged.

[0004] In a first aspect, embodiments of this application provide a protective cover, which includes a protective cover body, a telescopic member, and a driving component. Among them, the telescopic member and the driving component are installed in the protective cover body. The protective cover body is provided with a cavity for partially accommodating the folding part of the electronic device. The protective cover body is provided with a receiving cavity adapted to the telescopic member, and the receiving cavity forms an opening on a first side of the protective cover body close to the hinge cover of the electronic device.

[0005] Among them, during the fall of the protective cover, the driving component controls the telescopic member to change from a first state to a second state. In the first state, the telescopic member is located in the receiving cavity, and in the second state, at least a part of the telescopic member passes through the opening and is located outside the receiving cavity.

[0006] In a second aspect, embodiments of this application further provide an electronic device assembly, which includes an electronic device and the protective cover described in the first aspect. The electronic device includes two folding parts, a hinge, and a hinge cover. The two folding parts are connected by the hinge, and each folding part is provided with the protective cover, and the hinge is installed on the hinge cover.

[0007] Among them, when the electronic device is in an unfolded state, the openings of the two protective covers are arranged opposite to each other.

[0008] In the embodiments of the present application, by providing that the protective cover includes a protective cover body, a telescopic member, and a driving component, wherein the telescopic member and the driving component are installed in the protective cover body, the protective cover body is provided with a cavity for partially accommodating the folding part of the electronic device, the protective cover body is provided with a receiving cavity adapted to the telescopic member, and the receiving cavity forms an opening on the first side of the protective cover body close to the hinge cover of the electronic device; wherein, during the fall of the protective cover, the driving component controls the telescopic member to change from the first state to the second state. In the first state, the telescopic member is located in the receiving cavity, and in the second state, at least a part of the telescopic member passes through the opening and is located outside the receiving cavity. In this way, during the fall, for an electronic device in the unfolded state, the telescopic member can control the electronic device to enter the folded state, and for an electronic device in the folded state, the telescopic member can preferentially contact the collision position, thereby playing a buffering role to protect the electronic device.

[0026] See Figures 1 to 8 , an embodiment of the present application provides a protective cover. As shown in the figure, the protective cover 10 provided by the embodiment of the present application includes a protective cover body 11, a telescopic member 12, and a driving assembly 13. Among them, the telescopic member 12 and the driving assembly 13 are installed in the protective cover body 11. The protective cover body 11 is provided with a cavity for partially accommodating the folding part 21 of the electronic device. The protective cover body 11 is provided with a receiving cavity 112 adapted to the telescopic member 12, and the receiving cavity forms an opening on the first side 111 of the protective cover body 11 close to the hinge cover 24 of the electronic device.

[0027] Among them, during the fall of the protective cover 10, the driving assembly 13 controls the telescopic member 12 to change from the first state to the second state. In the first state, the telescopic member 12 is located in the receiving cavity 112. In the second state, the telescopic member 12 at least partially passes through the opening 113 and is located outside the receiving cavity 112.

[0028] In the related art, when the folding device is in the folded state, the hinge cover 24 and the part of the folding part 21 close to the hinge cover are usually exposed to the outside, so the hinge cover 24 or the folding part 21 is likely to contact the collision position first during the fall, resulting in damage to the hinge cover 24 or the folding part 21. Further, in the process of the hinge cover 24 contacting the collision position, the hinge cover 24 will be displaced and deformed, thereby squeezing the flexible screen 22 through the hinge, causing the flexible screen 22 to be damaged. In the related art, when the folding device is in the unfolded state, if the flexible screen 22 contacts the collision position during the fall, when there is a sharp object at the collision position, the flexible screen 22 is easily damaged. In the embodiment of the present application, the above-mentioned protective cover 10 is applied to an electronic device, such as a folding electronic device, to protect some components of the electronic device (such as the hinge cover 24, the folding part 21 and the flexible screen 22, etc.). Among them, the electronic device may include two folding parts, and the two folding parts are connected by a hinge 23, and the hinge 23 can be set on the hinge cover 24. In some embodiments, one of the two folding parts may be a part including the first middle frame 21a and the battery cover 21b, and the other folding part may be a part including the second middle frame 21c and the sub-screen 21d, and the flexible screen 22 is arranged on the side of the folding part away from the protective cover 10, and the flexible screen 22 is respectively connected to the two folding parts.

[0029] Optionally, in some embodiments, a slide groove may be provided in the receiving cavity 112, and the telescopic member 12 slides along the slide groove, thereby changing from the first state to the second state. A slide groove may also be provided on the telescopic member 12, and a sliding rod may be provided in the receiving cavity 112, and the telescopic member 12 is mounted on the sliding rod through the slide groove, and the telescopic member 12 may slide along the sliding rod, thereby changing from the first state to the second state.

[0030] Optionally, the surface of the protective cover body 11 facing or away from the folding portion 21 can be roughly rectangular, wherein the sides other than the first side can be folded to form a folded edge, and the folded edge and the surface of the protective cover body 11 facing or away from the folding portion 21 can be arranged at an angle of 90°. The three folded edges and the surface of the protective cover body 11 facing or away from the folding portion 21 enclose a cavity for partially accommodating the folding portion 21 of the electronic device. In some embodiments, the protective cover body 11 can be fixed to the folding portion 21 by snapping together the three folded edges. Of course, in some embodiments, the protective cover body 11 can also be fixed to the folding portion 21 by bonding.

[0031] It should be noted that in the normal use state, the driving component 13 can control the telescopic member 12 to be in the first state. At this time, the protective cover does not exceed the middle frame of the electronic device on the first side 111 of the electronic device. When it is detected that the protective cover is in a falling state, the driving component 13 can control the telescopic member 12 to change from the first state to the second state, that is, control the telescopic member 12 to extend out of the receiving cavity through the opening 113. At this time, the telescopic member 12 exceeds the middle frame of the electronic device on the first side of the electronic device, so that when the electronic device is in a folded state, the telescopic member 12 preferentially contacts the collision position (such as the ground), so as to prevent the hinge cover 24 of the electronic device from being displaced and deformed due to the collision, resulting in damage to the hinge cover 24 and the flexible screen 22. At the same time, it can prevent the folding part 21 of the electronic device from directly contacting the collision position (such as the ground), so as to prevent the folding part 21 of the electronic device from being damaged.

[0032] Optionally, in some embodiments, a leatherette 114 may be further provided on the side of the protective cover body 11 facing away from the folding part 21. The leatherette 114 may be adhesively fixed to the protective cover body 11 to cover or seal the components provided on the protective cover body 11.

[0033] It should be noted that the first side 111 of the protective cover body 11 close to the hinge cover 24 of the electronic device can be understood as: when the electronic device is in the unfolded state, the side of the protective cover body 11 provided on one folding part 21 facing the other folding part 21. Or rather, when the protective cover bodies 11 are provided on both folding parts, the first sides 111 of the two protective cover bodies 11 are arranged opposite to each other or are attached to each other. Or rather, the first side 111 of the protective cover body 11 close to the hinge cover 24 of the electronic device can be understood as: the side of the electronic device or the protective cover body 11 close to the hinge cover 24 in the length direction (such as Figure 9 the horizontal direction shown).

[0034] In the embodiments of the present application, by providing that the protective cover 10 includes a protective cover body 11, a telescopic member 12 and a driving assembly 13, wherein the telescopic member 12 and the driving assembly 13 are installed inside the protective cover body 11, the protective cover body 11 is provided with a cavity for partially accommodating the folding part 21 of the electronic device, the protective cover body 11 is provided with a receiving cavity 112 adapted to the telescopic member 12, and the receiving cavity forms an opening on the first side 111 of the protective cover body 11 close to the hinge cover 24 of the electronic device; wherein, during the falling process of the protective cover 10, the driving assembly 13 controls the telescopic member 12 to change from the first state to the second state. In the first state, the telescopic member 12 is located inside the receiving cavity 112, and in the second state, the telescopic member 12 at least partially passes through the opening 113 and is located outside the receiving cavity 112. In this way, during the falling process, for the electronic device in the unfolded state, the telescopic member 12 can be used to control the electronic device to enter the folded state, and for the electronic device in the folded state, the telescopic member 12 can preferentially contact the collision position, thereby playing a buffering role to protect the electronic device. Therefore, the embodiments of the present application reduce the risk of device damage of the electronic device, thereby improving the reliability of the electronic device during use and extending the service life of the electronic device.

[0035] Optionally, in some embodiments, the protective cover 10 further includes an acceleration sensor 14, the acceleration sensor 14 is electrically connected to the driving assembly 13, and the acceleration sensor 14 is used to detect whether the protective cover 10 is in the falling process.

[0036] In the embodiments of the present application, the acceleration sensor 14 can determine whether the protective cover 10 is in the falling process by the magnitude of the acceleration. For example, when the acceleration sensor 14 detects that the acceleration is greater than a preset threshold value, it can be determined that the protective cover 10 is in the falling process, otherwise, it is determined that the protective cover 10 is in the non-falling process, that is, the normal use state.

[0037] It should be understood that since the acceleration sensor 14 is provided inside the protective cover 10, the acceleration sensor 14 can be directly electrically connected to the driving assembly 13. In this way, the structure is simple and easy to implement.

[0038] Of course, in other embodiments, the acceleration sensor of the electronic device itself can be reused. For example, an acceleration sensor is provided in the folding portion 21. The driving component 13 is electrically connected to the acceleration sensor in the folding portion 21, or the driving component 13 is communicatively connected to the controller in the folding portion 21, and the controller in the folding portion 21 is electrically connected to the acceleration sensor in the folding portion 21. When the controller in the folding portion 21 determines that the electronic device is currently in a falling process through the acceleration sensor, a control signal is sent to the driving component 13, and the driving component 13 controls the telescopic member 12 to change from the first state to the second state based on this control signal.

[0039] Optionally, in some embodiments, the driving component 13 includes a control circuit 131 and at least one magnetic member 132. The magnetic member 132 includes a first electromagnet 1321 and a first magnet 1322. The first electromagnet 1321 is fixedly connected to the protective cover body 11, and the first electromagnet 1321 is electrically connected to the control circuit 131. The first magnet 1322 is fixedly connected to the telescopic member 12, and the first electromagnet 1321 and the first magnet 1322 are disposed opposite to each other.

[0040] In the embodiments of the present application, when the first electromagnet 1321 is in an energized state, the end of the first electromagnet 1321 facing the first magnet 1322 and the first magnet facing the first electromagnet 1321 have the same or opposite magnetic poles. In the case of having the same magnetic poles, the telescopic member 12 can be driven to move outside the protective cover body 11 under the mutual repulsive force of magnetism to change from the first state to the second state. In the case of having opposite magnetic poles, the telescopic member 12 can be driven to move inside the protective cover body 11 under the mutual attractive force of magnetism to change from the second state to the first state.

[0041] Optionally, the above control circuit 131 can be adhesively fixed to the protective cover body 11 through double-sided tape, and the control circuit 131 can be electrically connected to the first electromagnet 1321 through a flexible circuit board.

[0042] In some embodiments, the above first magnet can be a permanent magnet or an electromagnet, and no further limitation is made here.

[0043] Optionally, in some embodiments, an elastic member may be provided, and the elastic restoring force of the elastic member is used to drive the telescopic member 12 to move into the protective sleeve body 11, so that the telescopic member 12 remains in the first state when the first electromagnet 1321 is powered off. One end of the elastic member is connected to the telescopic member, and the other end is fixedly connected to the protective sleeve body 11. For example, in some embodiments, the driving assembly 13 further includes an elastic member, one end of the elastic member is fixedly connected to the telescopic member 12, and the other end is fixedly connected to the protective sleeve body 11. The elastic member is used to generate an elastic force for driving the telescopic member into the first state.

[0044] In the embodiment of the present application, when the first electromagnet 1321 is powered off, the elastic restoring force of the elastic member causes the telescopic member 12 to enter and remain in the first state. When the first electromagnet 1321 is powered on, the first electromagnet 1321 and the first magnet generate a repulsive magnetic force to overcome the elastic force of the elastic member, so as to control the telescopic member 12 to enter the second state from the first state and remain in the second state.

[0045] Optionally, the elastic member may be a spring. One end of the elastic member may be fixedly connected to the end of the telescopic member away from the opening, and the other end of the elastic member may be fixedly connected to the inner wall of the accommodating cavity 112 on the side away from the opening.

[0046] Optionally, in some embodiments, the opening 113 is disposed near the outer side of the protective sleeve body 11.

[0047] In the embodiment of the present application, the outer side of the protective sleeve body 11 may be understood as the side of the protective sleeve body 11 away from the folding portion. Since the opening 113 is disposed near the outer side of the protective sleeve body 11, the distance between the telescopic member 12 and the rotation center of the hinge 23 can be increased in the unfolded state, thereby increasing the torque of the telescopic member 12 during the process of driving the electronic device from the unfolded state to the folded state, and improving the reliability of the state change of the electronic device.

[0048] Optionally, in some embodiments, the number of the magnetic members 132 is three, and the three magnetic members 132 are sequentially distributed between two opposite second sides 115 of the protective sleeve body 11, and the second side is adjacent to the first side;

[0049] Wherein, the first electromagnet 1321 and the first magnet 1322 in the middle magnetic member 132 are used to generate a magnetic attraction force to drive the telescopic member 12 to change from the second state to the first state; the first electromagnet 1321 and the first magnet 1322 in the magnetic members 132 on both sides are used to generate a magnetic repulsive force to drive the telescopic member 12 to change from the first state to the second state.

[0050] In the embodiment of the present application, in the normal use state of the electronic device, the first electromagnet 1321 of the middle magnetic member 132 can be controlled to be in the energized state, and the first electromagnet 1321 of the magnetic members 132 on both sides can be controlled to be in the de-energized state. In the case where it is detected that the electronic device or the protective case is in the process of falling, the first electromagnet 1321 of the middle magnetic member 132 can be controlled to be in the de-energized state, and the first electromagnet 1321 of the magnetic members 132 on both sides can be controlled to be in the energized state.

[0051] It should be noted that since two magnetic members 132 are provided to drive the telescopic member 12 to change from the first state to the second state, the driving force for driving the telescopic member 12 to change from the first state to the second state can be increased, so as to ensure that there is sufficient driving force to ensure that the telescopic member 12 changes from the first state to the second state at the moment of falling. Therefore, the reliability of the state change of the telescopic member 12 is improved.

[0052] Optionally, in some embodiments, the telescopic member 12 is provided with a locking hole, and a locking platform is provided in the receiving cavity 112. In the first state, the locking platform is located in the locking hole so that the telescopic member 12 is detachably connected to the protective sleeve body 11.

[0053] In the embodiment of the present application, the above-mentioned telescopic member 12 can be arranged in a cuboid shape. A locking hole is provided on the first side surface of the cuboid, and a locking platform is provided at a position in the receiving cavity 112 corresponding to the locking hole. Wherein, the first side surface of the telescopic member 12 is adjacent to the second side surface of the telescopic member 12. The second side surface can be understood as the end surface of the telescopic member 12 facing the opening 113 when the telescopic member 12 is in the first state. The above-mentioned locking hole can be a blind hole provided on one side of the first side surface away from the second side surface; the above-mentioned locking platform can be a hemispherical protrusion. Under the action of the driving assembly 13, the locking platform can enter or slide out of the locking hole. In this way, due to the cooperation of the locking hole and the locking platform, in the first state, it is not necessary to continuously energize the middle magnetic member 132 to keep the telescopic member 12 in the first state. Therefore, the embodiment of the present application can reduce power consumption.

[0054] Optionally, in some embodiments, a clamping hole may be provided on one or more first sides adjacent to the second side, and one or more clamping platforms may be provided at positions corresponding to the clamping holes in the receiving cavity 112. Of course, in some embodiments, the telescopic member 12 may also be a cylinder, which is not further limited herein.

[0055] Optionally, in some embodiments, the protective cover 10 further includes a battery 15, and the battery 15 is electrically connected to the driving assembly 13.

[0056] In the embodiments of the present application, the battery 15 may be a rechargeable battery, and the control circuit 131 may include a charging control sub-circuit, so that the battery 15 can be charged through the reserved interface outside.

[0057] It should be understood that since the independent battery 15 is provided, it is not necessary to occupy the power resources of the electronic device itself. Of course, in some embodiments, the power supply of the electronic device itself can also be directly connected through the provided interface. For example, a battery is provided in the folding part 21, and the battery is electrically connected to the control circuit 131 through a wire.

[0058] Optionally, the battery 15 may be fixedly bonded by double-sided tape, and the battery 15 is electrically connected to the control circuit 131 through a flexible circuit board.

[0059] Optionally, in some embodiments, the receiving cavity 112 and the opening 113 extend from one folded edge to the other folded edge in two opposite folded edges of the protective cover body 11.

[0060] In the embodiments of the present application, the receiving cavity 112 and the opening 113 both include a first part located at the first folded edge, a second part located at the second folded edge, and a third part located on the protective cover body 11, wherein the first folded edge and the second folded edge are oppositely arranged. The telescopic member 12 includes three parts respectively located in the above-mentioned first part, second part, and third part. In this way, the area of the telescopic member 12 can be increased, and after the telescopic member 12 slides out of the receiving cavity 112, it can better surround the hinge cover 24, avoiding the hinge cover 24 from contacting the collision position, so as to further protect the flexible screen 22 and improve the reliability of the electronic device during use.

[0061] Optionally, in some embodiments, through holes may be provided in the telescopic member 12, guide rods are provided in the receiving cavity, and the through holes of the telescopic member 12 are sleeved on the guide rods, and the telescopic member 12 can slide along the guide rods. In this way, the sliding stability of the telescopic member 12 can be increased.

[0062] Optionally, in some embodiments, the telescopic member 12 may also be provided with a slide rail or a slide groove, and the receiving cavity may be provided with a slide groove or a slide rail. The slide groove and the slide rail cooperate to enable the telescopic member 12 to slide more stably, thereby improving the sliding stability of the telescopic member 12.

[0063] The embodiment of the present application further provides an electronic device assembly, the electronic device assembly comprising an electronic device and a protective cover, the electronic device comprising a hinge, a hinge cover and two folding parts, the two folding parts are connected by the hinge, each of the folding parts is installed with the protective cover, and the hinge is installed on the hinge cover;

[0064] Wherein, when the electronic device is in an unfolded state, the openings of the two protective covers are arranged opposite to each other.

[0065] Optionally, in some embodiments, when the electronic device is in the unfolded state and the electronic device assembly is in the process of falling, the electronic device is driven to change from the unfolded state to the folded state during the process in which the telescopic members in the two protective covers change from the first state to the second state.

[0066] In the present application embodiment, Figure 9 As shown, in the falling state, the electronic device is driven by the telescopic member to change from the unfolded state to the folded state, so that the flexible screen can be placed in direct contact with the sharp object 30 at the collision position, resulting in damage to the flexible screen. Figure 10 As shown, the risk of screen cracking due to the bulging of the middle of the flexible screen after a collision with one side of the electronic device in the unfolded state can be avoided. Therefore, the embodiment of the present application improves the reliability of the use of the electronic device.

[0067] Optionally, in some embodiments, when the electronic device is in a folded state and the electronic device components are in the process of falling, the telescopic parts in the two protective covers change from a first state to a second state, and in the second state, the height of the telescopic parts protruding from the protective cover body in the first direction is higher than or equal to the height of the hinge cover protruding from the protective cover body in the first direction.

[0068] In the embodiment of the present application, since in the second state, the height of the telescopic member protruding from the protective cover body in the first direction is higher than or equal to the height of the hinge cover protruding from the protective cover body in the first direction, the hinge cover can be prevented from contacting the collision position, thereby further reducing the risk of damage to the flexible screen and improving the reliability of the use of the electronic device.

[0069] Optionally, the first direction may be understood as the length direction of the electronic device, or may be understood as Figure 9 Horizontal direction shown.
