In one aspect, according to one embodiment of the present application, an electronic device protective case is provided that can be used to provide good protection for fragile parts on an electronic device, particularly a display screen on the electronic device, when the electronic device protective case is applied to the electronic device. The electronic device may be, for example, a commonly used electronic product such as a smart phone, a tablet computer, etc., which is not limited in the present application.

The electronic equipment protection shell comprises a shell body and an energy dissipation structure. Wherein the shell is at least partially made of brittle materials. The energy dissipating structure is disposed on the housing. The energy dissipation structure comprises a plurality of groove lines, and the groove lines are arranged on the shell in a grid-shaped structure. Wherein, be provided with a plurality of recesses on every recess line.

The electronic equipment protection shell of the embodiment of the application is characterized in that the shell material of the protection shell is improved, the traditional protection shell material (such as soft material) is abandoned, the shell part is creatively manufactured by adopting brittle materials, and the principle of breaking and dissipating energy of the brittle materials is actually utilized. Meanwhile, a special energy dissipation structure is further arranged on the shell of the protective shell and combined with application of brittle materials, so that the formed electronic equipment protective shell can play a role in protecting the fragile structure of electronic equipment, in particular the display screen of the electronic equipment after being applied to the electronic equipment. The electronic equipment protective housing provided by the embodiment of the application effectively solves the problem that the display screen is easy to crack and damage after the electronic equipment is subjected to impact force (such as falling and collision). The embodiment of the application can obviously enhance the protection effect on the display screen of the electronic equipment.

Moreover, it should be noted that, the protection shell of the electronic device according to the embodiment of the present application has a significant difference from the prior art in the protection principle adopted therein. In fact, in the embodiment of the application, after the electronic device is impacted, the impact energy received by the display screen of the electronic device can be reduced by dissipating the impact energy, so that the display screen of the electronic device is protected. Of course, the electronic device protecting case of the embodiment of the application is not limited to only protecting the display screen on the electronic device, and can also play a role in protecting other fragile structures on the electronic device.

Further, in the embodiment of the present application, the material of the protective case of the electronic device is designed to be a brittle material, and the brittle material can only generate small deformation under the action of external force (such as collision, impact, stretching, etc.), so that the electronic device is easy to break. The method utilizes the cracking principle of the brittle material to consume kinetic energy, so that the impact energy received by the display screen of the electronic equipment is smaller than the fracture resistance energy of the display screen of the electronic equipment, and the display screen of the electronic equipment can be protected finally. Furthermore, in order to further enhance the capability of impact energy dissipation, in embodiments of the present application, special energy dissipation structures are designed into the housing of the protective case of the electronic device. The energy dissipation structure has the effects that once the electronic equipment is impacted, the brittle material can be rapidly cracked and a large number of cracks are generated, and fracture mechanical phenomena such as expansion, bifurcation, intersection, expansion, convergence and the like of multiple cracks can be promoted, so that a large amount of impact energy acted on the electronic equipment can be converted into fracture energy of a new generated crack surface or fracture energy required by crack bifurcation, the impact energy can be effectively dissipated, the energy received by the display screen of the electronic equipment can be reduced in a manner of dissipating the impact energy, and the effect of protecting the display screen of the electronic equipment can be achieved.

The electronic equipment protecting shell can be designed into a rear cover of the electronic equipment, such as a battery cover and the like, and can be directly combined with the electronic equipment body, and the electronic equipment protecting shell is not required to be additionally provided for the electronic equipment. Of course, the electronic equipment protective housing of the embodiment of the application can be designed as a protective housing of the electronic equipment, and the protective housing and the electronic equipment can be installed together when in use.

In one embodiment of the present application, referring to fig. 1 and 2, an electronic device protective case of an embodiment of the present application includes a case and an energy dissipation structure 102 disposed on the case; wherein the housing may be a rear cover (e.g., a battery cover) of the electronic device. And, the housing includes a body region 101 and an edge region 103 disposed around the body region. The energy dissipating structure 102 includes a plurality of groove lines, and the plurality of groove lines form a grid-like structure on the housing. As shown in fig. 3, a plurality of grooves 1021 are formed on the groove line. The grooves 1021 are, for example, triangular grooves, but of course, the grooves 1021 may be other shapes, which is not limited in the embodiment of the present application.

In the above embodiment, the main body area 101 is a main part of the housing, and the edge area 103 is disposed around the main body area 101 and is mainly used for being connected to the electronic device, so that the whole electronic device protection shell can be integrated with the electronic device body. In the embodiment of the application, the edge area 103 can be detachably connected with the electronic device, so that the whole electronic device protection shell can be replaced conveniently.

Wherein at least one of the body region 101 and the edge region 103 may be made of a brittle material. For example, glass materials, ceramic materials, etc. may be used, and it should be noted that embodiments of the present application are not limited to the use of brittle materials described above, but may be other brittle materials known to those skilled in the art. When the electronic device suddenly falls or is impacted, a strong impact force acts on the electronic device, and at this time, the electronic device protective shell in the embodiment of the application is easy to break and fracture due to the brittleness of the material, meanwhile, as shown in fig. 5a and 5b, the energy dissipation structure 102 on the electronic device protective shell can assist in rapidly cracking the brittle material and greatly generating cracks 1022, and can promote fracture mechanics phenomena such as multi-crack expansion, bifurcation, intersection, expansion, convergence and the like, so that a great amount of impact energy acting on the electronic device can be converted into fracture energy of a new crack surface generated or fracture energy required by crack bifurcation, thereby dissipating the impact energy, reducing the energy received by the electronic device display screen, and playing a good role in protecting the electronic device display screen.

In an alternative embodiment of the present application, at least one of the body region 101 and the edge region 103 is formed from a brittle material that is self-healing. Considering that in this embodiment, the electronic device protection case of the embodiment of the present application is directly used as the rear cover of the electronic device, that is, is a part of the electronic device, and the rear cover cannot be used normally and is not easy to be replaced once broken, so that the materials of the main body area 101 and the edge area 103 of the case are selected from brittle materials capable of self-healing, for example, a glass material capable of self-healing is used. The self-healing material cannot be directly used in a display screen due to the opaque or semitransparent characteristic, but the back cover applied to the electronic equipment has no display problem, so the self-healing material is just applicable. The material design in the embodiment of the application can well solve the problem that the rear cover of the electronic equipment is scrapped due to the fact that the brittle material cannot be recovered after being broken, and also solves the problem that the self-healing material cannot be used in a display screen. Therefore, the scheme of the embodiment of the application reasonably combines the advantages of the anti-cracking and self-healing materials of the electronic equipment.

On the protective shell of the electronic device, when a large-area fracture occurs in the main body area 101, the self-healing brittle material can self-identify the damaged position and complete self-repairing of the crack at the damaged position (the broken line part), and the healing process can be specifically shown in fig. 6 a-6 c. Such self-healing brittle materials are typically copolymerized from a variety of compounds.

In an alternative embodiment of the present application, the self-healing brittle material is a low molecular weight ether-thiourea polymer. For the low molecular weight ether-thiourea polymer, thiourea groups in the polymer structure form a high-density hydrogen bond network, and the high-density hydrogen bond can ensure the mechanical property of the polymer; the hydrogen bond is easy to break and form, and the polymer can self-heal under pressure without heating or other special treatment by introducing structural elements capable of activating hydrogen bond pair exchange. The material has no transparency of the glass material of the display screen, is difficult to apply to the position of the display screen, but is feasible in the position of the back cover of the electronic equipment which is not required to be displayed, and can accelerate the healing of cracks by utilizing Van der Waals force or externally applying some external load, so that the healing mode is very simple and complex operation is not required.

According to the electronic equipment protective shell, when the electronic equipment protective shell is made of the self-healing brittle material, the protective effect on the display screen of the electronic equipment can be enhanced, the electronic equipment protective shell can be reused, and the electronic equipment protective shell is not easy to damage.

The electronic equipment protecting shell can be used as the rear cover of the electronic equipment, and can be designed as the protecting sleeve of the electronic equipment for use, and the protecting shell and the electronic equipment can be installed together when in use.

In another embodiment of the present application, the protective case for electronic device of the embodiment of the present application, as shown in fig. 8 and 9, includes a housing and an energy dissipation structure 102 disposed on the housing, wherein the housing is a protective case for electronic device, and can be directly sleeved on the electronic device when in use. And, the housing includes a body region 101, a transition region 104 disposed around the body region 101, and a bezel region 105 disposed around the transition region 104. The energy dissipating structure 102 includes a plurality of groove lines, and the plurality of groove lines form a grid-like structure on the housing. As shown in fig. 3, a plurality of grooves 1021 are formed on the groove line. The grooves 1021 are, for example, triangular grooves, but of course, the grooves 1021 may be other shapes, which is not limited in the embodiment of the present application.

Wherein the main body region 101 is the main part of the housing, which is designed to be made of brittle material in the present application, which is significantly different from the existing electronic device protective case made of soft material. The body region 101 also has the energy dissipating structure 102 formed thereon, and as can be seen in fig. 8 and 9, the energy dissipating structure 102 includes a plurality of recessed lines that can be formed in the body region 101 by etching. These groove lines are equivalent to forming a preset crack network on the main body area 101 of the casing, once the casing is impacted, the brittle material can cause certain cracks 1022 to be generated on the casing, and the cracks 1022 can be continuously branched, expanded and converged under the action of the preset crack network, and simultaneously a large number of new cracks can be generated, so that finally the whole casing made of the brittle material is cracked in a large area to form a crack network distribution, thus the impact energy directly acting on the display screen can be dissipated, and the impact energy acting on the display screen is smaller than the fracture energy which can be resisted by the display screen, thereby protecting the display screen from being damaged.

The transition region 104 connecting the main body region 101 and the frame region 105 may be made of the same brittle material as the main body region 101, but the embodiment of the present application is not limited thereto. The brittle material may be, for example, glass material or ceramic material, and the skilled person can flexibly select according to specific needs.

Wherein the bezel area 105 is used to protect a middle or side frame portion of the electronic device. In an embodiment of the present application, the frame area 105 may be made of a soft material, for example, a material such as silicone, rubber, or the like. The electronic equipment protective shell is mainly used for generating larger deformation so as to facilitate disassembly, assembly and the like between the electronic equipment and the electronic equipment protective shell, and meanwhile, the electronic equipment protective shell can also play a role in transferring energy when falling or colliding.

It should be noted that, in the embodiment of the present application, at least one of the main body region 101 and the transition region 104 is made of a brittle material. That is, either the body region 101 or the transition region 104 is made of a brittle material; it is also possible that the body region 101 and the transition region 104 are both made of brittle materials, and those skilled in the art can flexibly select them according to actual needs, which the present application is not limited to.

In an alternative embodiment of the application, at least one of the body region 101 and the transition region 104 is made of a self-healing brittle material. Thus, when the main body region 101 breaks in a large area, the damaged position can be identified by the self-healing property of the material, and the self-repairing of the crack at the damaged position can be completed. Wherein the self-healing brittle material adopts a low molecular weight ether-thiourea polymer. For the low molecular weight ether-thiourea polymer, thiourea groups in the polymer structure form a high-density hydrogen bond network, and the high-density hydrogen bond can ensure the mechanical property of the polymer; the hydrogen bond is easy to break and form, and the polymer can self-heal under pressure without heating or other special treatment by introducing structural elements capable of activating hydrogen bond pair exchange.

Compared with the prior art, the electronic equipment protective housing disclosed by the embodiment of the application does not need to be additionally provided with the air bag and other protective structures when the electronic equipment protective housing is designed as the protective housing of the electronic equipment for use, so that the protective housing is simple in structure, lighter and thinner, and the user experience can be improved well.

The protective case for electronic devices of the present embodiment of the application, wherein the energy dissipation structure 102 comprises a plurality of groove lines distributed on the surface of the case. Further, these groove lines are distributed over the body region 101 of the housing. The pattern formed is a grid-like structure, as can be seen in fig. 7 and 8, and may be, for example, an orthogonal grid-like structure, a diamond-like diagonal grid-like structure, or a honeycomb-like structure. It should be noted that, the shape of the energy dissipation structure in the embodiment of the present application is not limited to the above-mentioned grid structures, but may be other grid structures as long as the crack is generated, which is not limited by the present application.

According to the electronic equipment protective shell, when the electronic equipment protective shell is subjected to larger impact, the shell can be cracked in a large area, and in the cracking process, impact energy can be absorbed in a large amount, so that dissipation of impact energy is realized. When the impact energy is dissipated to a certain extent, the display screen of the electronic equipment is not excessively impacted, so that the display screen can be prevented from being damaged.

The protective case for electronic equipment according to the embodiment of the present application, as shown in fig. 2 and 9, further includes an energy guiding structure. The energy guiding structure comprises a plurality of triangular grooves 106. And the energy guiding structure is arranged on the housing at an edge position of the energy dissipating structure 102. For example, the plurality of triangular grooves 106 are evenly distributed over the edge locations of the energy dissipating structure 102.

It should be noted that, in the embodiment of the present application, the groove in the energy guiding structure is not limited to the triangular groove 106, but may be a groove with other shape, as long as the groove has a tip. This is because: in the embodiment of the application, the arrangement of the energy guiding structure is actually equivalent to arranging a plurality of cracking points on the edge position of the shell, and the main purpose of the energy guiding structure is to induce the generation of crack tips at the cracking points in the falling process of the electronic equipment, further guide the crack to expand to the energy dissipating structure 102, play a role in generating the crack and promoting the crack to continuously expand and branch, and finally convert a great amount of kinetic energy of impact into fracture energy even if the crack is continuously increased, so as to greatly dissipate the energy of the impact, thereby playing a role in protecting important structures on the electronic equipment, in particular a display screen.

The protective case for electronic device according to the embodiment of the present application, the energy guiding structure includes a plurality of triangular grooves 106, wherein one tip of the triangular grooves 106 faces the side of the energy dissipating structure 102. The design is equivalent to that the electronic equipment protective shell is respectively provided with the cracking point and the preset cracks, so that after the electronic equipment is impacted, more cracks are rapidly formed on the electronic equipment protective shell, and the kinetic energy of the impact can be dissipated by means of the continuously generated cracks so as to protect the display screen on the electronic equipment.

In an alternative embodiment of the application, see fig. 2 and 9, the energy guiding structure comprises a plurality of triangular grooves 106, one of the tips of the triangular grooves 106 being opposite the end of the groove line in the energy dissipating structure 102. In this embodiment, the triangular grooves 106 in the energy guiding structure are aligned with the groove lines in the energy dissipating structure 102, i.e. the initiation points are aligned with the preset cracks, which helps to form cracks for dissipating impact energy on the protective casing of the electronic device more quickly, and can greatly enhance the energy dissipating capability to better protect the display screen on the electronic device.

According to the electronic equipment protecting shell, the shell can be of a multi-layer structure.

In an alternative embodiment of the application, see fig. 3, the housing comprises a base layer 107 and a protective layer 108 bonded to at least one surface of the base layer 107. The protective layer 108 may be made of a light, thin, flexible, and high-toughness material, so as to form a protective film on the substrate layer 107. Those skilled in the art can flexibly select an appropriate material as needed, and the present application is not limited thereto. The purpose of providing the protective layer 108 in the embodiment of the present application is to: after the brittle material is broken, the integrity of the brittle material can be ensured, broken particles or fragments and the like are prevented from directly flying out, and the fragments are prevented from piercing the electronic equipment body or scratching a user.

Here, the protective layer 108 may be provided only on one surface of the base layer 107, or the protective layer 108 may be provided on both surfaces of the base layer 107. When the protective layers 108 are provided on both surfaces of the base layer 107, the materials of the protective layers on both surfaces may be the same or different, and may be flexibly adjusted as needed by those skilled in the art, which is not limited by the present application.

Referring to fig. 4, in the embodiment of the present application, when the electronic device is impacted, a crack 1022 on the protective case of the electronic device may propagate along a groove 1021 on the groove line.
