Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments of the present invention are merely for convenience of description and are not to be construed as limiting the present invention.

As shown collectively in fig. 1 to 3, the present embodiment discloses smart glasses. Comprises a spectacle frame 1 and spectacle legs 2 hinged with the spectacle frame 1; the heat dissipation device is characterized by further comprising a soaking plate 3 arranged at the hinged position of the glasses frame 1 and the glasses legs 2, wherein the soaking plate 3 dissipates heat generated by the heating components 4 in the glasses frame 1 or/and the glasses legs 2 by utilizing the heat dissipation principle that internal working media (the filling rate is 80%, liquid fluids such as pure water, ammonia water or acetone are filled, the evaporation latent heat of water is the largest and the cheapest, and a large amount of heat can be easily boiled and quickly taken away under low pressure, and is the most common working media) are changed in gas-liquid two-phase; the shell of the soaking plate 3 is made of a super-elastic foil with the elastic limit of 6-10% and the elastic modulus of less than or equal to 150Gpa, the thickness of the super-elastic foil is 10-250 um (namely the wall thickness of the shell), and the strength is greater than or equal to 700 Mpa. The martensite phase transformation point of the super-elastic foil is lower than-20 ℃, and the material shows good recoverable super-elastic deformation at the temperature of-20 ℃ to 100 ℃.

Wherein, the glasses legs 2 are symmetrically provided with two first hinged lugs, one end of the glasses frame 1 is provided with second hinged lugs which are in one-to-one correspondence with the two first hinged lugs; be formed with between two articulated ears and dodge the space, in one end of vapor chamber 3 stretched into picture frame 1, the other end stretched into mirror leg 2 with the help of dodging the space, and stretched into vapor chamber 3 in mirror leg 2 and bond through heat conduction gum and the components and parts 4 that generate heat in mirror leg 2. In some other embodiments, the temple 2 is provided with a first hinged seat, and one end of the spectacle frame is provided with a second hinged seat corresponding to the first hinged ear and located at the inner side; one end of the soaking plate 3 extends into the spectacle frame 1, the other end of the soaking plate extends into the spectacle legs 2 through an avoiding space, and the soaking plate 3 positioned at the hinged part is positioned on one side of the second hinged seat facing to the human face (the soaking plate is prevented from being exposed to affect the appearance). The soaking plate 3 can be bent into an L shape after being processed into a rectangle according to the structural characteristics of the intelligent glasses, or can be directly processed into an L shape, or can be directly rectangular, and the limitation is not provided herein. In some embodiments, the heating element 4 is disposed in the lens frame 1, and the soaking plate 3 extending into the lens frame 1 is bonded to the heating element 4 through a heat-conducting back adhesive.

In order to facilitate clear understanding of the technical solution and the technical effect of the present embodiment, the following description is made on the principle according to which the present embodiment is developed and designed:

when the material is bent and deformed, elastic deformation is firstly generated, and after the external force is removed, the deformation of the material can be completely recovered. When the strain exceeds the elastic deformation limit of the material, plastic deformation is generated, the plastic deformation is unrecoverable, the generated plastic deformation is accumulated when the material is bent for multiple times to generate plastic deformation, and when the accumulated plastic deformation exceeds the plastic limit of the material, the material is broken and fails. The vapor chamber has the advantages that the shell sealing is broken, the vapor chamber fails, the capillary holes are closed or the capillary cores are broken in the case of the liquid absorption core structure, the power of the vapor chamber is reduced, and the heat dissipation capacity is extremely reduced.

If the material is to undergo tens of thousands of bending deformations without failure, a feasible design is to make the bending deformation material always in the elastic deformation zone during repeated bending. For example, when a metal material is always in an elastic deformation region, the fatigue bending life of the metal material can reach dozens of thousands of times, and the service time can reach more than ten years; once the material yields into the plastic deformation zone, the material inevitably breaks after multiple bends due to the limited elongation of the material.

Therefore, when the soaking plate 3 used in the smart glasses is designed, the bending deformation (i.e., strain) of the material used for manufacturing the soaking plate 3 can be always controlled within the elastic deformation limit of the material, and the bending service life of the soaking plate is prolonged while the heat dissipation effect is ensured.

FIG. 4 shows a mechanical model of a material undergoing bending deformation, the material having a thickness H, a bending radius R, and a bending angle θ, when the material is bent, the material on the outer side undergoes the maximum tensile deformation, the tensile deformation decreases toward the inside of the material, and the dotted line in the middle is shown as a neutral layer, i.e., a non-deformable layer that is neither stretched nor compressed, within which the material on the inner side undergoes symmetrical compressive deformation and the material on the innermost side undergoes the maximum compressive deformation; the maximum tensile or compressive deformation that the material undergoes can be calculated.

The outermost length of the material is (R + H) theta, and the length of the neutral layer is (R + H/2) theta, then the maximum strain produced by the material is: [ (R + H) θ - (R + H/2) θ) ]/(R + H/2) θ ═ H/(2R + H); the strain values of the materials can be obtained by substituting different bending radii R and the thicknesses of the foils, as shown in the following table 1;

TABLE 1 Strain corresponding to foils of different thicknesses at different bending radii

TABLE 2 modulus of elasticity and elastic limit of common materials

Material	Modulus of elasticity (GPa)	Elastic limit (%)
			Copper alloy	～105	<0.6
Stainless steel	～210	<1
			Aluminium	～77	<0.5
Titanium alloy	～102	<2
			Nylon	3	<2
Silica gel	1.2	>20
			Super elastic alloy	≤150	6-10

In order to ensure the fatigue life of the material, a part of the elasticity, such as 0.5%, needs to be reserved to ensure that the material can withstand tens of thousands of bending without breaking. Therefore, if the case of the soaking plate 3 is made of a metal foil having a thickness of 0.01mm to 0.25mm, the soaking plate 3 may be repeatedly bent without failure when the bending radius is large, but the device is not strong yet and is easily deformed, and the yield is low. Once the bend radius is reduced to 2mm, the strain of the material quickly exceeds 2%, even more than 4%, which causes plastic deformation of the material (common metal and alloy materials), and the soaking plate 3 cracks and fails quickly when repeatedly bent. Polymeric materials (e.g., silica gel, etc.), although having high elasticity, have been difficult to use as sealing materials for a long time because of their molecular structure not being dense, and their thin thickness, air permeability, thermal conductivity, high and low temperature impact resistance, and reliability against bending fatigue, etc., and their heat dissipation effects are inferior to those of metallic materials.

Superelasticity refers to the phenomenon that a sample generates strain much larger than the ultimate elastic strain amount under the action of an external force, but the strain can still automatically recover when the sample is unloaded. That is, in the parent phase, stress-induced martensitic transformation occurs due to the applied stress, so that the alloy exhibits a mechanical behavior different from that of a normal material, has a much larger elastic limit than that of a normal material, and no longer obeys hooke's law. Compared with the shape memory property, the super elasticity has no thermal participation. In general, superelasticity refers to the fact that stress does not increase with increasing strain over a range of deformation.

For example, the elastic deformation of the super-elastic alloy can reach 6 to 10 percent, and the elastic modulus is less than or equal to 150 Gpa; if the super-elastic alloy is adopted, good elastic bending deformation performance can be obtained when the shell wall thickness of the soaking plate 3 is 0.01 mm-0.25 mm (preferably 0.1 mm-0.2 mm), and the bending deformation is always in an elastic deformation area under the bending state that R is more than 2 mm; when the external force is removed, the deformation of the steel plate can be completely recovered, so that the bending life is greatly prolonged; can satisfy the heat dissipation demand that intelligence glasses and other folding portable electronic product rotated the department.

The shell of the vapor chamber 3 in the embodiment comprises an evaporation side shell 31 and a condensation side shell 32 which are buckled and welded together and enclose a closed cavity (the vacuum degree is-2 Pa); and brazing is preferred, so that high reliability of multi-bending sealing can be ensured. The evaporation side casing 31 is bonded to the heating element 4 in the temple 2 by a heat conductive adhesive. A wick structure 33 and a plurality of supporting structures 34 arranged at intervals are arranged in the vacuum sealed cavity (to prevent the evaporation side shell 31 and the condensation side shell 32 from deforming to affect the sealed cavity when vacuum pumping is performed), and a steam channel 35 is formed between two adjacent supporting structures 34. In this embodiment, the overall thickness of the soaking plate 3 is 1mm or less. Wick structure 33 is a porous plastic, a porous polymer, a porous metal, or a multi-layer woven mesh, among others. Wick structure 33 is no greater than 0.5mm thick.

In this embodiment, at least part of the support structure 34 has one end directed towards the inside of the temple 2 and the other end directed towards the outside of the temple 2; in the folded state, the distance between two adjacent support structures 34 at the hinge joint of the spectacle frame 1 and the spectacle legs 2 gradually decreases from the outer side (the side departing from the human face) to the inner side (the side facing the human face). In still other embodiments, in the folded condition, the distance between two adjacent support structures 34 at the hinge of the frame 1 and the temple 2 is constant.

The heat dissipation function of the soaking plate 3 is mainly realized by the gas-liquid two-phase change of the working medium. The heat dissipation process of the soaking plate 3 comprises four main steps of conduction, evaporation, convection and condensation. The heat dissipation principle is as follows: the heat generated by the heat source (the heating element 4) enters the closed cavity through the heat conduction of the evaporation side shell 31, and the working medium in the liquid absorption core structure 33 close to the heat source is quickly vaporized after absorbing the heat and simultaneously takes away a large amount of heat; the steam in the steam passage 35 diffuses from the high pressure region to the low pressure region (i.e., low temperature region), and when the steam contacts the condensing side casing 32 having a relatively low temperature, the steam is rapidly condensed into a liquid state and releases heat energy; the working medium condensed into liquid state returns to the heat source under the action of capillary force generated by the fine structure of the liquid absorption core structure 33, so that one-time heat conduction circulation is completed, and a two-way circulation system with the working medium having two coexisting vapor and liquid phases is formed.

In some embodiments, the wick structure 33 includes a first wick portion that conforms to the inner side wall of the evaporation side housing 31 and a second wick portion that conforms to the inner side wall of the condensation side housing 32; the first liquid absorbent core and the second liquid absorbent core enclose a vapor chamber; one end of the support structure 34 is provided on the evaporation-side casing 31 or the condensation-side casing 32, and avoidance ports that avoid the support structure 34 are provided on the first liquid-absorbing core portion and the second liquid-absorbing core portion.

In still other embodiments, the support structure 34 is an integral structure with the evaporation side shell 31 or the condensation side shell 32. Preferably, the support structure 34 is integrally formed by punching or etching with the evaporation-side casing 31 or the condensation-side casing 32.

In still other embodiments, the first liquid absorbent core is integrally formed with the evaporation side housing 31 and the second liquid absorbent core is integrally formed with the condensation side housing 32. That is, the first and second wick portions are formed by removing portions of the housing, preferably by wet etching or precision stamping.

In order to further increase the buffer strain, in some embodiments, an elastic buffer energy absorption layer or a trench structure is disposed on the outer sidewall of the soaking plate 3 (which can increase the elasticity and effectively avoid local over-bending or disperse the stress). Preferably, high elasticity buffering energy-absorbing layer such as PI, PP, PE and thickness are not more than 50um, and the depth that forms the slot makes this effective thickness who goes out the casing be not less than 10 um.

In this embodiment, the superelastic foil is preferably made of a titanium-nickel alloy; the atomic percentage of the titanium element and the nickel element in the titanium-nickel alloy is more than or equal to 40 percent, and the atomic percentage of the rest elements is less than or equal to 10 percent; and the atomic percentage of all elements in the titanium-nickel alloy is 100 percent. Wherein the remaining elements include one or more of copper, iron, niobium and zirconium.
