Example one

Referring to fig. 1 to 3, a temple 1 according to an embodiment of the present application includes: a temple outer casing 11 and a temple inner casing 12. The temple case 11 includes a flat case 111 and an arc case 112, and the flat case 111 is connected to the arc case 112. The temple inner casing 12 includes a straight inner casing 121 and an arc-shaped inner casing 122, and the straight inner casing 121 is connected to the arc-shaped inner casing 122. The arc-shaped inner shell 122 comprises an arc-shaped inner layer 1221 and an arc-shaped outer layer 1222, the hardness of the arc-shaped outer layer 1222 is less than the hardness of the arc-shaped inner layer 1221 and the temple outer shell 11, and the arc-shaped inner layer 1221 is in fit connection with the arc-shaped outer layer 1222. The flat inner housing 121 is connected to the flat outer housing 111. For example, the flat inner housing 121 and the flat outer housing 111 may be connected by a snap structure. The arcuate inner layer 1221 is adhesively secured to the arcuate outer shell 112 by an adhesive.

The arc-shaped outer layer 1222 of the temple 1 is a surface for being attached to the skin of a human body when a user wears the head-mounted display device, and is located at the ear hanging part of the temple 1. In the present embodiment, the arcuate inner layer 1221 has a stiffness less than the stiffness of the arcuate outer layer 1222 and the temple housing 11. Make mirror leg hangers department have elasticity, the flexible improves and wears the comfort, can suit the user of different head circumferences. The arc inner layer 1221 of the hard structure is directly bonded with the arc outer shell 112 of the hard structure through the binder, and the hard structure are directly bonded and fixed through the binder, so that the bonding process difficulty is reduced, the production efficiency is improved, the situation that the flexible structure is connected with the hard structure, the flexible structure needs to be bonded through the hot melt adhesive, the process requirement is severe, and the production efficiency is not improved.

The arc-shaped shell 112 can be designed to be a thin-walled structure, that is, the thickness of the arc-shaped shell 112 is smaller than that of the straight shell 111, so that the arc-shaped shell 112 has elastic deformation capability. It is noted that the arcuate housing 112 and the flat housing 111 are sheet-like bodies, where the "thickness" of the arcuate housing 112 and the "thickness" of the flat housing 111 are defined as the extension of the arcuate housing 112 or the flat housing 111 in the thickness direction of the temple housing 11. For example, the thickness contrast between the curved outer shell 112 and the flat outer shell 111 can be clearly seen in the top view of the temple of fig. 10.

The temple outer casing 11 may be of a hard adhesive structure, for example, a plastic material such as PC, ABS, etc., and the straight inner casing 121 and the arc-shaped inner casing 1221 of the temple inner casing 12 may be of a hard adhesive structure, that is, a plastic material such as PC, ABS, etc. The straight outer shell 111 and the straight inner shell 121 have almost no deformability, and a glasses leg cavity is formed inside the straight outer shell 111 and the straight inner shell 121, so that electronic components can be conveniently installed, and the electronic components are protected from deformation. The electronic component can be a circuit board, a chip, a sensor and the like. The outer arc layer 1222 may be of soft gel structure, i.e., the outer arc layer 1222 may be of silicon-based material such as silicon gel, TPE, etc. The relative ebonite of flexible glue structure laminating skin is more comfortable, and the flexible glue part is easily deformed moreover, when it contacts with user's head, can adapt to user's head and enclose the area of contact that has carried out deformation and increased its user's head, can produce great frictional force, and the difficult landing of glasses.

Referring to fig. 3, in one possible embodiment, the arc-shaped inner layer 1221 has a bottom wall 1221a and side walls 1221b disposed at both sides of the bottom wall 1221a, the side walls 1221b are abutted against the arc-shaped outer shell 112, and the side walls 1221b are adhesively secured to the arc-shaped outer shell 112 by an adhesive to form a temple cavity.

In this embodiment, through setting up lateral wall 1221b, can strut diapire 1221a and arc shell 112 for have certain interval between the two, form the mirror leg chamber, thereby conveniently hold electronic components in the mirror leg intracavity, for example hold circuit board, chip, sensor etc.. In addition, the side wall 1221b protrudes from the bottom wall 1221a, glue can be more easily and uniformly adhered, the adhesion effect is improved, and the stability of the adhesion structure is good. The side wall 1221b and the arc-shaped shell 112 are directly bonded, and the bottom wall 1221a does not need to be bonded, so that glue is saved.

Referring to fig. 3, in one possible embodiment, the arcuate outer layer 1222 wraps the sidewall 1221b, and the arcuate outer layer 1222 wraps the side of the bottom wall 1221a that faces away from the arcuate housing 112.

In this embodiment, the arc-shaped outer layer 1222 of the soft rubber structure covers the bottom wall 1221a and the side wall 1221b, so that the contact area between the soft rubber structure and the skin of the human body is increased, and the comfort and the friction are improved. The big area of flexible glue structure has played the effect of protection arc inlayer 1221, and when arc inlayer 1221 appeared splitting, the arc outer 1222 of flexible glue structure covered arc inlayer 1221, therefore the whole outward appearance of mirror leg and use all have no influence. The arc-shaped inner layer 1221 may be designed to be thin and light, and may be easily broken when externally expanded. Because the ebonite crackle appears, the elastic deformation ability of hangers department of mirror leg can strengthen to some extent, can adapt to the user of different head circumferences, wears the effect better. The arc-shaped outer layer 1222 may be coated on the surface of the arc-shaped inner layer 1221 by a two-color injection molding process. The thickness of the inner arcuate layer 1221 may be about 0.3mm to about 0.7mm and the thickness of the outer arcuate layer 1222 may be about 0.6mm to about 1.0 mm. Referring to fig. 4, the inner arc-shaped layer 1221 and the outer arc-shaped layer 1222 are both sheets, and the term "thickness of the inner arc-shaped layer 1221" should be understood as the thickness of the sheet.

Referring to fig. 4, in one possible embodiment, the arc-shaped inner layer 1221 is provided with a hollow 1221d, and the arc-shaped outer layer 1222 has a body 1222a and a protrusion 1222b connecting the body 1222 a. The body 1222a is attached to the arc-shaped inner layer 1221, and the protrusion 1222b extends to the hollow portion 1221 d. For example, the bottom wall 1221a of the arc-shaped inner layer 1221 may be provided with a through hole to form the hollow portion 1221 d.

The hollow-out portions 1221d arranged on the arc-shaped inner layers 1221 increase the elastic deformation capacity of the arc-shaped inner layers 1221, and deformation caused by stress is facilitated. After repetitious usage, there is the cracked condition of ebonite in arc inlayer 1221, when arc inlayer 1221 local fracture for mirror leg hangers department can have bigger deflection, further improves and wears the comfort, can suit the user of different head circumferences. The plurality of protrusions 1222b are disposed on the arc-shaped outer layer 1222 to protrude into the hollow 1221d, so that the wall thickness of the arc-shaped inner shell 122 is uniform. The outer arcuate layer 1222 may be injection molded onto the inner arcuate layer 1221 with a uniform wall thickness for uniform shrinkage during the cooling process.

Referring to fig. 6, in a possible embodiment, a plurality of gaps 1221c may be formed on the side wall 1221b, and the gaps 1221c are sequentially formed along the length direction of the side wall 1221 b. It should be noted that the arc-shaped inner layer 1221 has a long bar shape, and the "length direction of the side wall 1221 b" defined herein should be understood as the length direction of the arc-shaped inner layer 1221, i.e., the length direction of the temple 1. In this embodiment, the arc-shaped inner layer 1221 is the weakest point in the inner temple shell 12, and the notch 1221c is positioned to facilitate deformation of the temple by providing a plurality of notches 1221c in the side wall 1221 b. The position of the gap 1221c is a position which is easy to break, and in the use process of the glasses, after the glasses leg 1 is outwards deformed for multiple times, it is desirable that the arc-shaped inner layer 1221 can break at the gap 1221c, so as to further facilitate the deformation of the glasses leg 1. Since the arc-shaped inner layer 1221 is covered with the arc-shaped outer layer 1222, the arc-shaped inner layer 1221 can be bonded together without separation (for example, the two layers are integrated by two-color injection molding), and even if the arc-shaped inner layer 1221 is broken, the connection and the positioning between the two layers are not affected.

For example, referring to fig. 6, the slits 1221c may be arranged in pairs on the opposite side walls 1221b of the arc-shaped inner layer 1221 with the pairs of slits 1221c being located opposite to each other. The expression "opposite" here may be a positional relationship in which a line connecting between the paired slits 1221c is substantially perpendicular to the direction in which the arc-shaped inner layer 1221 extends in the longitudinal direction. The opposed pair of slits 1221c is more favorable for deformation of the temple 1 at the same position.

With continued reference to fig. 6, a first portion of the plurality of breaks 1221c can be disposed on the sidewall 1221b bounding the cutout 1221 d. The side wall 1221b of the position and the non-hollowed-out portion in the bottom wall 1221a together constitute a boundary of the hollowed-out portion 1221 d. A second portion of the plurality of cutouts 1221c may be disposed on the boundary side wall 1221b that does not define the cutout 1221d, i.e., the side wall 1221b at that location is not sufficient to border the cutout 1221d, but rather is connected to the cutout of the bottom wall 1221 a. As such, the side wall 1221b is weaker at the position of the cutout 1221c of the first portion than at the position of the cutout 1221c of the second portion, and the temple bar 1 is more easily deformed and broken at the position of the cutout 1221c of the first portion than at the position of the cutout 1221c of the second portion (to further facilitate the deformation). By this design, the temple 1 can be deformed in a desired specific position.

Referring to fig. 5 and 6, in a possible embodiment, a plurality of protrusions 1121 are formed at intervals along the length direction of the arc-shaped housing 112, and each protrusion 1121 is inserted into a corresponding gap 1221 c. Therefore, when the assembly is carried out, the positions of the protrusions 1121 and the notches 1221c are in one-to-one correspondence, so that the arc-shaped outer shell 112 and the arc-shaped inner shell 122 are accurately positioned, the assembly is convenient, and the assembly efficiency is improved. Therefore, the gap 1221c is positioned and easily deformed.

Referring to fig. 7 to 9, in a possible embodiment, the temple 1 further includes a decoration ring 13, and a first locking groove 131 and a second locking groove 132 are respectively disposed on two opposite sides of an inner wall of the decoration ring 13. The arcuate housing 112 has a fixed catch 1122 and the arcuate outer 1222 has a resilient catch 1222 c. The decoration ring 13 is sleeved on the temple outer shell 11 and the temple inner shell 12, the fixing buckle 1122 is clamped in the first clamping groove 131, and the elastic buckle 1222c is clamped in the second clamping groove 132.

In this embodiment, the fixing clip 1122 and the elastic clip 1222c are respectively provided at both sides of the temple 1, thereby facilitating the detachment of the decoration ring 13. During disassembly, the decoration ring 13 is manually rotated towards the elastic buckle 1222c, the elastic buckle 1222c can be compressed, the interference magnitude of the fixed buckle 1122 side is reduced, and meanwhile, the decoration ring 13 can be pulled out through outward force application, so that labor is saved.

Referring to fig. 1, 5, and 7-9, in one possible embodiment, the temple 1 further includes a wire connecting terminal 14, and the wire connecting terminal 14 is disposed between the arc-shaped inner shell 122 and the arc-shaped outer shell 112 and away from one end of the straight outer shell 111 and the straight inner shell 121. The connection terminal 14 may be located inside the decoration ring 13, i.e., the connection terminal 14 is formed between the temple outer housing 11 and the temple inner housing 12, which are wrapped by the decoration ring 13. This binding post 14 can be the female seat of Type _ C, and the data line that can be used to external Type _ C interface connects electronic equipment, and binding post 14 also can be other structures such as Micro _ USB, and this application does not limit to this. The connection terminal 14 may be attached to the end of the temple case 11 using a double-sided tape. In the embodiment of the present application, the decoration ring 13 may be used to fasten the bonding between the temple outer housing 11 and the temple inner housing 12, and when the temple 1 is deformed, the decoration ring 25 may make the connection between the connection terminal 14 and the data line plug more stable. A circuit board 15 may be provided in the temple 1, one end of the circuit board 15 being electrically connected to the connection terminal 14. The circuit board 15 may be a flexible circuit board which is adhered to the inner wall of the temple housing 11 along the temple extension direction.

Referring to fig. 6, 7 and 10, in one possible embodiment, the extension length of the arc-shaped casing 112 is smaller than that of the straight casing 111 in the thickness direction of the temple casing 11, so that the arc-shaped casing 112 has a thin-walled structure with elastic deformability. And the arc inner layer 1221 of the position of the inner shell 12 of the temple corresponding to the arc outer shell 112 is also set to be a thin-wall structure, and the middle part is provided with a hollow part 1221d, so that the ear hanging part of the temple 1 has better deformability, and the outward-extending action can be realized. The arc-shaped outer shell 112 and the arc-shaped inner layer 1221 are connected in a glue bonding mode, and noise generated by friction between shells cannot occur when the shells are outwards expanded.

For example, correspondingly, in the thickness direction along the temple outer casing 11, the extension length of the arc-shaped inner casing 122 corresponding to the position of the arc-shaped outer casing 122 is greater than the extension length of the straight inner casing 121 corresponding to the position of the straight outer casing 111. Therefore, the connection between the inner shell 12 and the outer shell 11 of the glasses leg is tight, and the overall appearance of the glasses leg is neat and beautiful.
