The electronic device protective case provided in the embodiment of the present application is described in detail with reference to fig. 1 to fig. 10 through a specific embodiment and an application scenario thereof.

According to one embodiment of the present application, an electronic device protective case is provided. When the electronic equipment protective sleeve is used, the protective sleeve can be sleeved outside the electronic equipment, and the electronic equipment, particularly a display screen on the electronic equipment, can be well protected when the electronic equipment falls.

The electronic device protective cover provided by the embodiment of the application, referring to fig. 1 to 7, includes a protective cover body 1, an energy conversion assembly 2 and a shape memory structure 3; the shape memory structure 3 is connected with the protective sleeve body 1; the energy conversion component 2 is arranged on the protective sleeve body 1 or the shape memory structure 5; when the electronic device is dropped, the energy conversion assembly 2 drives the shape memory structure 3 to transform from a first shape 301 to a second shape 302, as shown in fig. 1 and 2, respectively, in the thickness direction of the protective sheath body 1, the thickness of the second shape 302 is greater than that of the first shape 301.

The embodiment of the application provides an effectual protection scheme for electronic equipment, through set up shape memory structure 3 on the electronic equipment protective sheath, when electronic equipment 4 takes place to fall, can be based on shape memory structure 3 takes place chain deformation in the twinkling of an eye, if shape memory structure 3 can become the expanded protective airbag of volume, and like this, electronic equipment 4 is after falling, set up on the protective sheath body 1 shape memory structure 3 can contact earlier and fall the face, supports electronic equipment complete machine unsettled again, avoids electronic equipment's display screen direct collision to fall the face on, just so can effectively protect electronic equipment and the display screen on the same.

The electronic equipment protective sleeve provided by the embodiment of the application can be sleeved outside the electronic equipment when in application, and is convenient to disassemble and assemble. The electronic equipment protective sleeve can well protect electronic equipment, particularly a display screen on the electronic equipment protective sleeve.

In the embodiment of the application, an effective protection scheme is provided for the electronic device, especially for the display screen thereon, when the electronic device protective case is sleeved outside the electronic device 4, once the electronic device 4 falls, the shape memory structure 3 on the electronic device protective case can be instantly deformed and changed into an expanded protective airbag, so that the thickness of the protective case body 1 is increased, and the display screen 41 of the electronic device 4 can be effectively protected; the scheme provided by the embodiment of the application improves the capability and effect of protecting the electronic equipment.

Referring to fig. 1, 2 and 10, in the event of a drop of the electronic device 4, the shape memory structure 3 disposed on the protective cover body 1 is configured to be capable of transforming from the first shape 301 to the second shape 302, and in the second shape 302, the thickness of the protective cover body 1 is significantly greater than the thickness of the display screen 42 of the electronic device 4, and is also greater than the thickness of the display screen 42 in the first shape 301, which is advantageous for the protective cover body 1 to effectively protect the display screen 42 by using the instantaneous increase of the thickness after the electronic device 4 drops on the ground 6.

With continued reference to fig. 10, the floor 6 has sand 7 or impurities with high hardness, which may have many sharp edges and corners, and once touching the display screen 42 of the electronic device 4, the display screen 42 is a brittle material such as glass, and is prone to cracking due to stress concentration. The electronic equipment protective sleeve provided by the embodiment of the application is characterized in that the shape memory structure 3 on the protective sleeve body 1 is changed from the first shape 301 to the second shape 302, and then the whole electronic equipment 4 can be supported on a falling surface (such as the ground 6) in a suspending way, so that sand particles 7 and the like on the ground 6 cannot contact the display screen 42 on the electronic equipment 4, and the display screen 42 of the electronic equipment can be effectively protected.

When the shape memory structure 3 is in the first shape 301 as shown in fig. 1, the shape memory structure 3 itself has a cavity, but the space of the cavity is relatively small. During the dropping process of the electronic device 4, the shape memory structure 3 can be rapidly transformed into the second shape 302 as shown in fig. 2 due to the stimulation, at this time, the space inside the shape memory structure 3 becomes large, so that the thickness of the protective case body 1 is obviously increased, even if the electronic device 4 drops on the ground 6, the sand 7 on the ground 6 can not contact the display screen 42, and the display screen 42 can be effectively protected, as shown in fig. 10.

It is understood that in the embodiment of the present application, the first shape 301 is the initial shape of the shape memory structure 3, and referring to fig. 1, the protective sheath body 1 can effectively protect the electronic device from normal use. The second shape 302 is a deformed shape of the shape memory structure 3, and when the electronic device 4 falls, the space in the shape memory structure 3 can be rapidly enlarged to become a protective airbag, see fig. 2.

In the embodiment of the present application, the protective sheath body 1 is made of, for example, thermoplastic polyurethane elastomer rubber (TPU), which is a polymer material between rubber and plastic. As the protective sleeve, the electronic equipment can be effectively protected, and a good buffering effect can be achieved after the electronic equipment is impacted.

In some examples of the present application, the sensing signal generated by the electronic device 4 when falling can control the energy conversion assembly 2 to generate light energy to drive the shape memory structure 3 to transform from the first shape 301 to the second shape 302.

It will be appreciated that the electronic device may generate a sensing signal when dropped. It should be noted that the sensing signal may be generated by the electronic device itself, for example, by using a gyro sensor disposed on a main board in the electronic device. The sensing signal may also be generated by the protective sheath body 1, for example, a gyroscope sensor may be disposed in the protective sheath body 1.

In an embodiment of the present application, the energy conversion assembly 2 is capable of generating light energy, which may be used to stimulate the shape memory structure 3 to deform, i.e. transform from the first shape 301 to the second shape 302. That is, the shape memory structure 3 is designed in the embodiments of the present application to be deformed by light energy. On the basis, the shape memory structure 3 is made of a photo-induced shape memory polymer material, for example.

The shape memory structure is a Shape Memory Polymer (SMP) material, which is a novel functional polymer material and has the characteristics of both plastics and rubber. Shape memory polymers are a class of polymer materials obtained by molecular combination and modification of general polymer materials by applying modern polymer physics theory and polymer synthesis and modification technology, such as polymer materials like polyethylene, polyisoprene, polyester, copolyester, polyamide, copolyamide, polyurethane and the like, and are subjected to molecular design and molecular structure adjustment, so that the polymer materials are endowed with a certain shape (initial state) under certain conditions, and when external conditions change, the shape can be correspondingly changed and fixed (deformed). If the external environment changes again in a specific way and law, they can be reversibly restored to the initial state. At this point, the cycle of "memory initial state-fixed deformation state-recovery initial state" is completed.

In the embodiment of the present application, the shape memory structure 3 may be made of a photo-induced shape memory polymer material (i.e., photo-induced SMP), which is prepared by introducing some specific photochromic genes (PCG) into a main chain and a side chain of a polymer, and when the photo-induced photochromic genes (PCG) are irradiated by ultraviolet light, the photo-isomerization reaction of the photochromic genes (PCG) occurs, so that the state of the molecular chain is significantly changed, and the material is macroscopically shown to be deformed under the stimulation of light energy.

In some examples of the present application, referring to fig. 3, 7 and 8, the energy conversion assembly 2 includes a substrate 21, and a power supply 22 and a light emitter 23 disposed on the substrate 21, wherein a light emitting surface of the light emitter 23 is disposed toward the shape memory structure 3; the sensing signal generated by the electronic device 4 when falling can control the power supply component 22 to supply power to the light-emitting component 23, and the light-emitting component 23 emits light when being powered on to convert the shape memory structure 3 from the first shape 301 to the second shape 302.

The substrate 21 is used for carrying the power supply component 22, the light emitter 23 and other components, and realizing electrical conduction of different functional devices.

The power supply 22 is, for example, a coin cell battery, which can be used to supply current to the light emitter 23. The light emitter 23 is capable of generating light energy after receiving the current provided by the power supply 22, and the shape memory structure 3 is rapidly driven to transform from the first shape 301 to the second shape 302 by the light energy.

It will be appreciated that a sensor signal may be generated when the electronic device 4 is dropped, and the sensor signal may be a condition that drives the energy conversion assembly 2 to generate light energy. After the power supply 22 is powered on (or receives an electrical signal), the light emitter 23 is driven to emit light instantly to form light energy, so as to stimulate the shape memory structure 3 on the protective sheath body 1 to transform from the first shape 301 to the second shape 302, thereby protecting electronic devices.

In some examples of the present application, the protective case for electronic devices further comprises a first sensing chip 5;

when the first sensing chip 5 receives a sensing signal generated by dropping the electronic device, the power supply 22 is powered on and provides electric energy for the light emitter 23, and the light emitter 23 emits ultraviolet light towards the shape memory structure 3 to drive the shape memory structure 3 to be converted from the first shape 301 to the second shape 302.

That is to say, in the embodiment of the present application, a receiving chip for receiving a drop signal of the electronic device 4, that is, the first sensing chip 5, is disposed inside the protective case body 1. After the first sensing chip 5 receives a signal sent by the electronic device 4 after dropping, the power supply 22 is powered on to supply current to the light emitter 23, and the light emitter 23 can generate light energy, and on this basis, the shape memory structure 3 is made of a photoinduced shape memory material. Thus, the shape memory structure 3 made of the photo shape memory material can be increased in volume by stimulation with light energy.

In some examples of the present application, referring to fig. 4, the substrate 21 includes a first circuit board 211 and a second circuit board 212 connected to the first circuit board 211, where the first circuit board 211 and the second circuit board 212 form a vertical bending transition structure at a connection position, the first circuit board 211 is a rigid circuit board, and the second circuit board 212 is a flexible circuit board;

The hard circuit board mainly plays a role in supporting functional devices.

For example, the power supply member 22 and the first sensor chip 5 are respectively mounted on two opposite surfaces of the first circuit board 211. The first circuit board 211 can be used for carrying the power supply part 22 and the first sensing chip 5, and the power supply part 22 and the first sensing chip 5 are arranged by using a space in a thickness direction, so that the plane size of the first circuit board 211 can be reduced.

The light emitting body 23 is an LED lamp capable of emitting ultraviolet light, and the emitted ultraviolet light can irradiate the shape memory structure 3, so as to stimulate the shape memory structure 3 to deform.

Further, when the first sensing chip 5 receives a signal, it immediately issues a command to enable the coin-shaped battery (power supply 22) to provide a current, and the current is transmitted to the second circuit board 212 through the first circuit board 211, so that the light-emitting body 23 emits an ultraviolet ray after being energized, so as to stimulate the shape memory structure 3 to deform.

The light emitter 23 generates heat when emitting light, and is separated from the first sensing chip 5, so as to prevent the generated heat from affecting the first sensing chip 5.

Will luminous body 23 sets up on the flexible circuit board (promptly the second circuit board 212), the flexible circuit board can buckle, like this, is convenient for adjust the orientation of luminous body 23 to make it can be faced to shape memory structure 3 is luminous, and light just can be better shines like this on shape memory structure 3, is favorable to shape memory structure 3 responds to the light energy stimulus fast and takes place deformation.

Of course, the materials of the side frame portion 11, the base 12, and the cover 13 may be the same or different, and the embodiment of the present invention is not limited thereto.

For example, the shape memory structures 3 are provided in four, and the four shape memory structures 3 are respectively provided at four corner portions of the side frame portion 11. In fact, when the electronic device 4 falls, the four corner positions are most likely to be collided to cause the display screen 42 to be broken, and the shape memory structures 3 are respectively arranged on the four corner portions of the side frame portion 11, so that the four corner portions of the electronic device 4 can be well protected.

It should be noted that the shape memory structure 3 in the embodiment of the present application can be realized by a blow molding process. Because the material is soft, the material has certain elasticity. When irradiated with ultraviolet rays, the ultraviolet rays expand in volume, and the wall thickness is further reduced, thereby further increasing the elasticity.

The end of the stop 31 is provided with a guide angle so that it is easy to assemble but difficult to disassemble, thereby facilitating fixation.

Wherein, assembly portion 32 is the annular structure, and it does shape memory structure 3's fixed slot position, it also assembles on protective sheath body 1 is last be provided with in the installation hole site 14 connecting portion 15, connecting portion 15 can be the protruding structure of annular, connecting portion 15 can extrude extremely in the assembly portion 32, with assembly portion 32 forms clearance fit, be favorable to with shape memory 3 is more stable, more firmly is connected on protective sheath body 1.

The deformation part 33 is a hollow part of the airbag, the volume is smaller under the first shape 301, and when the deformation part 33 is irradiated by the ultraviolet rays of the luminous body 23, the deformation part expands instantly, and the volume is larger. So that when falling to the ground, the particle impurities on the ground 6 cannot contact the display screen 41, thereby effectively protecting the display screen 41.

In some examples of the present application, referring to fig. 9 and 10, the protective cover body 1 is sleeved outside the electronic device 4; a second sensing chip 434 is arranged in the electronic device 4, and the second sensing chip 434 is used for detecting a falling state of the electronic device 4 and sending a generated sensing signal to the first sensing chip 5;

The electronic device 4 further comprises a device housing 41, a display screen 42 and a main board assembly 43; the display screen 42 is arranged on the device housing 41 and encloses with the device housing 41 to form an accommodating cavity; the main board assembly 43 is disposed in the accommodating cavity, and the main board assembly 43 includes a main board 431, and a processor (e.g., a CPU) 432, a sensor 433, and a second sensing chip 434 disposed on the main board 431.

The sensor 433 is, for example, a gyroscope or a gravity sensor, and is configured to acquire a sensing signal when the electronic device 4 falls; when the sensor 433 acquires a sensing signal that the electronic device 4 is dropped, the processor 432 transmits the sensing signal to the first sensing chip 5 in the energy conversion assembly 2 through the second sensing chip 434.

For example, be provided with second response chip 434 in electronic equipment, second response chip 434 sets up to for example the transmission signal chip, first response chip 5 in the protective sheath body 1 then sets up to the receiving signal and responds to the chip, is provided with gyroscope (sensor 433) on the mainboard 431 in the electronic equipment 4 generally, and the change of the gyro response acceleration of gravity on the mainboard 431, when electronic equipment 4 fell the in-process, the change of the acceleration of gravity can be inducted out in the twinkling of an eye to the gyro on the mainboard 431.
