Referring to fig. 1 and 2, a glass housing 10, which may be applied to a mobile terminal, includes a bezel portion 100, a cover portion 200, and a heat sink 300. The frame portion 100 is connected to the edge of the cover plate portion 200, and the two may be integrally formed. The cover portion 200 and the frame portion 100 enclose an open cavity 102. The frame portion 100 has a first outer surface 110 and a first inner surface 120, the first outer surface 110 and the first inner surface 120 are disposed opposite to each other, the first outer surface 110 is disposed away from the open cavity 102 (in contact with the outside), and the first inner surface 120 is disposed close to the open cavity 102 and defines a partial boundary of the open cavity 102. At least one of the frame portion 100 and the cover portion 200 is provided with the storage space 101, that is, the storage space 101 may be provided only on the frame portion 100, only on the cover portion 200, or both the frame portion 100 and the cover portion 200. The receiving space 101 communicates the open cavity 102 with the outside. In other words, one end of the storage space 101 communicates with the open cavity 102, and the other end communicates with the outside.

Referring to fig. 1 and 2, the heat sink 300 is filled in the receiving space 101, so that one end of the heat sink 300 is adjacent to the open cavity 102 and the other end of the heat sink 300 is adjacent to the outside (i.e., the outside atmosphere). Due to the existence of the heat radiator 300, heat is absorbed at one end, close to the open cavity 102, of the heat radiator 300, and then the absorbed heat is quickly transferred to one end, close to the outside, of the heat radiator 300, so that the heat is discharged to the atmosphere through one end, close to the outside, of the heat radiator 300, finally the heat generated in the open cavity 102 is quickly discharged to the outside in time, the temperatures of the glass shell 10 and the mobile terminal are reduced, and the temperature rise and scalding of the glass shell 10 due to heat accumulation cannot be caused, and the user experience is not influenced; meanwhile, heat generated in the working process of the mobile terminal is timely discharged through the heat radiator 300, adverse effects on the working performance of hardware due to overheating are avoided, and the service life of the mobile terminal is prolonged.

Referring to fig. 11, when the cover portion 200 is placed on a reference horizontal plane 30, the tangent planes at various positions on at least one of the first outer surface 110 and the first inner surface 120 and the reference horizontal plane 30 form a plurality of dihedral angles, and values greater than 90 ° and less than 90 ° exist in the plurality of dihedral angles. That is, only a plurality of tangent planes on the first outer surface 110 and the reference horizontal plane 30 may be clamped to form a dihedral angle having a value larger than 90 ° and smaller than 90 °, in other words, there are two intersecting lines between a virtual plane 20 perpendicular to the reference horizontal plane 30 and the first outer surface 110; or, only a plurality of tangent planes on the first inner surface 120 and the reference horizontal plane 30 are clamped to form dihedral angles with values larger than 90 ° and smaller than 90 °, in other words, there are two intersecting lines between a virtual plane 20 perpendicular to the reference horizontal plane 30 and the first inner surface 120; alternatively, the plurality of tangential planes on both the first outer surface 110 and the first inner surface 120 and the reference horizontal plane 30 are sandwiched to form a dihedral angle having a value larger than 90 ° and smaller than 90 °, in other words, there are two intersecting lines between a virtual plane 20 perpendicular to the reference horizontal plane 30 and the first outer surface 110, and there are two intersecting lines between another virtual plane 20 perpendicular to the reference horizontal plane 30 and the first inner surface 120. This allows the glass envelope 10 to be ergonomically designed, while the glass envelope 10 will create a particularly sparkling glass feel through the reflection and refraction effects of the light.

The cover portion 200 has a second outer surface 210 and a second inner surface 220 oppositely disposed, the second outer surface 210 is disposed away from the open cavity 102 (in contact with the outside), and the second outer surface 210 is connected to the first outer surface 110. A second inner surface 220 is disposed proximate to the open cavity 102 and defines another portion of the boundary of the open cavity 102, the second inner surface 220 being connected to the first inner surface 120.

Referring to fig. 1 to 6, in some embodiments, the heat dissipation body 300 includes a heat dissipation layer 310, and the heat dissipation layer 310 fills all of the receiving space 101, that is, all of the receiving space 101 is used to receive the heat dissipation layer 310. The main body of the heat dissipation layer 310 is made of graphene material, and nano silver particles are mixed in the graphene material according to a certain mass ratio. The graphene material has excellent heat conduction performance, so that heat generated in the open cavity 102 is timely discharged to the outside; the nano silver particles have good reflection characteristics on light, so that a part of the glass shell 10 can generate a flashing bright spot, and the appearance effect of the glass shell 10 is improved. The nano silver particles have metal characteristics, which can improve the mechanical strength of the heat dissipation layer 310 and ensure that the heat dissipation layer 310 has good impact resistance.

Graphene materials have good chemical stability, thereby improve the ability of heat dissipation layer 310 to corrode strong acid and strong base, can not produce the clearance because of corroding between heat dissipation layer 310 and storage space 101, guarantee heat dissipation layer 310 to storage space 101's sealing ability, avoid liquid or dust from the external world to get into in the spacious mouth 102, ensure that glass housing 10 possesses stronger liquid pollution prevention and dust pollution prevention's ability. The graphene material has good anti-seismic performance, and when the glass housing 10 is impacted by external force, the heat dissipation layer 310 does not crack, so that the sealing capability of the heat dissipation body 300 to the accommodating space 101 is further ensured.

Referring to fig. 1 to 3, the receiving space 101 includes a plurality of receiving holes 101a, the plurality of receiving holes 101a are disposed on the cover plate 200 at intervals, the receiving holes 101a penetrate through the second outer surface 210 and the second inner surface 220 of the cover plate 200, the plurality of receiving holes 101a are not communicated with each other inside the cover plate 200, the heat dissipation layer 310 completely fills the receiving holes 101a, the receiving holes 101a may have a regular cylindrical structure, and at this time, the heat dissipation layer 310 filled in the receiving holes 101a is also cylindrical. Of course, the housing hole 101a may be a polygonal hole, and the cross section of the housing hole 101a may be irregular. The number of the receiving holes 101a of the cover plate 200 can be increased or decreased as necessary according to the specific heat dissipation condition and structural strength of the glass housing 10.

Referring to fig. 4, in addition to the receiving hole 101a formed in the cover plate 200, the receiving hole 101a may be formed in the frame 100, that is, the receiving hole 101a formed in the frame 100 penetrates the first outer surface 110 and the first inner surface 120. The accommodating hole 101a of the frame portion 100 is also filled with the heat dissipation layer 310, so that the channel for the heat in the open cavity 102 to be discharged outwards is increased, the rapid discharge of the heat in the open cavity 102 is facilitated,

referring to fig. 5 and 6 together, the receiving space 101 may include a communication chamber 101b in addition to the receiving hole 101 a. A communication chamber 101b is provided inside the cover plate portion 200, and the communication chamber 101b communicates the respective accommodation holes 101a on the cover plate portion 200 with each other. In the process of heat dissipation, because the heat distribution is not uniform everywhere in the open cavity 102, the end of the heat dissipation layer 310 close to the open cavity 102 absorbs heat, and in the process of heat transmission towards the end of the heat dissipation layer 310 close to the outside, the heat will be uniformly distributed on the portion of the heat dissipation layer 310 in the communication cavity 101b, so that the heat is rapidly discharged from the end of the heat dissipation layer 310 close to the outside, and the problem that the heat dissipation layer 310 in the partial accommodating hole 101a is difficult to discharge heat in a short time is avoided, thereby causing the local temperature of the glass housing 10 to be too high.

Referring to fig. 7 to 9, in some embodiments, the heat sink 300 includes a heat dissipation layer 310 and a heat conduction layer 320, the heat dissipation layer 310 fills a portion of the receiving space 101 away from the open cavity 102, and the heat dissipation layer 310 is disposed adjacent to the outside; the heat conduction layer 320 fills the portion of the receiving space 101 close to the open cavity 102, and the heat conduction layer 320 is disposed adjacent to the open cavity 102. In fact, the heat conductive layer 320 is stacked on the heat dissipation layer 310. The heat distribution in the open cavity 102 is not uniform, and due to the rapid heat conduction effect of the heat conduction layer 320, the heat will be uniformly distributed on each part of the heat conduction layer 320, so that the heat of each part on the heat conduction layer 320 is almost simultaneously discharged through the heat dissipation layer 310, the temperature of each part of the glass housing 10 is kept consistent, and the local over-high temperature is avoided.

The heat conducting layer 320 is made of a heat conducting silica gel material, which has a high heat conductivity coefficient, so that the heat conducting layer 320 can uniformly distribute the heat in the open cavity 102, so that the heat can be uniformly discharged from the heat dissipating layer 310, and thus, the local high temperature of the glass housing 10 can be avoided.

Referring to fig. 7, the receiving space 101 includes a mounting groove 101c and a receiving hole 101a, the mounting groove 101c is concavely formed on the second inner surface 220 of the frame part 100, and the receiving hole 101a penetrates through the bottom surface of the mounting groove 101c and the second outer surface 210 of the frame part 100, i.e., the receiving hole 101a communicates the mounting groove 101c with the outside. Of course, the housing holes 101a are spaced apart on the cover plate portion 200, and the shape of the housing holes 101a may be substantially the same as the shape of the housing holes 101 a. Referring to fig. 8, the heat dissipation layer 310 can fill the entire space of the containing hole 101a and the partial space of the mounting groove 101c away from the open cavity 102, and the heat conduction layer 320 fills the remaining partial space of the mounting groove 101c (i.e. the space close to the open cavity 102). Of course, referring to fig. 9, the heat dissipation layer 310 may fill only the entire space of the accommodation hole 101a, and the heat conduction layer 320 fills the entire space of the installation groove 101 c.

Referring also to fig. 10-12, the second outer surface 210 and the second inner surface 220 may be both parallel planes, i.e., the second outer surface 210 and the second inner surface 220 are both parallel to the reference horizontal plane 30, defining the virtual plane 20 perpendicular to the reference horizontal plane 30, in which case the virtual plane 20 is perpendicular to both the second outer surface 210 and the second inner surface 220. Therefore, the frame portion 100 has the following three states: referring to fig. 11, there are two intersecting lines between a virtual plane 20 and the first outer surface 110 of the frame portion 100 (corresponding to the frame portion 100 being in the outer-buckled state). Alternatively, referring to fig. 12, there are two intersecting lines between a virtual plane 20 and the first inner surface 120 of the frame portion 100 (corresponding to the frame portion 100 being in the inner-buckled state). Alternatively, referring to fig. 10, not only the virtual plane 20 having two intersecting lines with the first outer surface 110 of the frame portion 100, but also the other virtual plane 20 having two intersecting lines with the first inner surface 120 of the frame portion 100 (corresponding to the frame portion 100 being in the inside-outside buckled state). Of course, the intersection line may be a straight line or a curved line.

When the frame portion 100 is in the external reverse buckling state, the first outer surface 110 of the frame portion 100 conforms to the ergonomic design, so that a user can conveniently and rapidly grab the glass shell 10 smoothly at one time, the glass shell 10 is prevented from slipping, and the grabbing convenience is improved; meanwhile, when the glass housing 10 is held in a human hand, the user's comfort in holding is enhanced.

When the frame portion 100 is in the inner-reverse buckling state, the structure properly increases the installation space of the open cavity 102, so that other components (such as the main board assembly) can be conveniently installed in the open cavity 102, the special bending shape of the first inner surface 120 is beneficial to the bonding force between the other components and the glass housing 10, and the installation stability of the other components is improved, and meanwhile, a decoration or a decoration layer can be arranged on the first inner surface 120 of the frame portion 100, so that the expansion space of the mobile terminal with the glass housing 10 in the visual design is improved.

In addition, when the frame portion 100 is in the inside-outside buckled state, the reflection and refraction effects of the glass housing 10 on light rays can be changed, so that the glass housing 10 has a particularly shining glass texture, the appearance effect of the glass housing 10 is improved, and consumers have unique visual experience in sense. Of course, when the frame portion 100 is in the external reverse buckling state or the internal reverse buckling state, the effect of changing the reflection and refraction of light can be also achieved.

In some embodiments, the first outer surface 110 and the first inner surface 120 transition smoothly from place to place without undulating edges:

for example, referring to fig. 10, the first outer surface 110 and the first inner surface 120 are both smooth curved surfaces, and when the virtual plane 20 is perpendicular to the reference horizontal plane 30, there are two intersecting lines between one virtual plane 20 and the first outer surface 110, and there are two intersecting lines between the other virtual plane 20 and the first inner surface 120, that is, the glass housing 10 is in an inside-outside buckled state.

For another example, referring to fig. 11, the first outer surface 110 is a smooth curved surface; the first inner surface 120 comprises an inner vertical plane 121 and an inner transition curved surface 122, the inner vertical plane 121 is arranged perpendicular to the second inner surface 220, the end of the inner transition curved surface 122 is connected with the inner vertical plane 121 and the second inner surface 220 respectively, and the inner transition curved surface 122 is tangent to the inner vertical plane 121 and the second inner surface 220 at the connection part respectively, so that smooth transition of the whole first inner surface 120 is ensured. At this time, there are two intersecting lines between the virtual plane 20 and the first outer surface 110, and there is only one intersecting line between the first inner surface 120 and the virtual plane 20; the glass envelope 10 is in an outer flip-flop state.

For another example, referring to fig. 12, the first inner surface 120 is a smooth curved surface; the first outer surface 110 comprises an outer vertical plane 111 and an outer transition curved surface 112, the outer vertical plane 111 is perpendicular to the second outer surface 210, the ends of the outer transition curved surface 112 are respectively connected with the outer vertical plane 111 and the second outer surface 210, and the outer transition curved surface 112 is respectively tangent to the outer vertical plane 111 and the second outer surface 210 at the connection part, so that smooth transition of the whole first outer surface 110 is ensured. At this time, there are two intersecting lines between the virtual plane 20 and the first inner surface 120, and there is only one intersecting line between the first outer surface 110 and the virtual plane 20; the glass envelope 10 is in an inside-out state.

In some embodiments, the first inner surface 120 is not a smooth transition everywhere, and the first outer surface 110 is convex away from the open cavity 102 with an outer ridge. Similarly, the first inner surface 120 does not have a smooth transition everywhere, and the first inner surface 120 is recessed away from the open cavity 102 to form an inner ridge. Both the inner edge and the outer edge may be present on the frame portion 100, or only one of them may be present on the frame portion 100. Due to the existence of the inner edge line and the outer edge line, the reflection and refraction paths of light can be changed to form different reflection effects, and the appearance visual effect of the glass shell 10 is improved.

The invention also provides a mobile terminal which comprises a display component, a mainboard component and the glass shell 10, wherein the mainboard component is arranged in a cavity enclosed by the display component and the glass shell 10. Because this mobile terminal adopts this glass shell 10, make mobile terminal accord with human engineering design, strengthen mobile terminal in snatching, the convenience and the travelling comfort of the in-process of gripping, improve mobile terminal's outward appearance visual effect simultaneously.
