A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] like Figures 1 to 6As shown, the utility model provides a wearable optical device. Taking a head-mounted optical hat as an example, the wearable optical device includes a wearing piece 1, an optical component 2 and a pad 3. The wearing piece 1 is a main body for wearing on the head of the user 9. The wearing piece 1 includes an outer shell 11 and an inner shell 12. The outer shell 11 and the inner shell 12 enclose an installation space 13, and the installation space 13 is used to accommodate the optical component 2. In addition, the inner shell 12 can be worn on the head of the user 9, and the inner shell 12 has a light-transmitting area 120. The optical component 2 is arranged in the installation space 13, and the light-emitting end of the optical component 2 is arranged toward the inner shell 12, so that the emitted light of the optical component 2 can be emitted through the light-transmitting area 120; the pad 3 includes a front pad 30, and the front pad 30 is located on the inner side of the front end of the wearing piece 1. When in use, the front pad 30 is attached to the forehead of the user 9 to block the emitted light from irradiating the eyes of the user 9.

[0044] like Figure 2 , Figure 3 and Figure 4 As shown, the outer shell 11 has an inner wall 111, and the inner shell 12 has an outer wall 121 and a wearing space formed by the outer wall 121. An installation space 13 is formed between the inner wall 111 of the outer shell 11 and the outer wall 121 of the inner shell 12; and the wearing space is configured as a spherical shell or an ellipsoidal shell that matches the head of the user 9. The optical component 2 generally includes a flexible circuit substrate 20 and a light source 21 disposed on the flexible circuit substrate 20. The light source 21 is disposed toward the outer wall 121 of the inner shell 12 and directly faces the light-transmitting area 120 on the inner shell 12, so that the emitted light of the light source 21 can penetrate the light-transmitting area 120 and irradiate the head of the user 9. When the head-mounted optical cap is a hair growth cap, the emitted light can stimulate the scalp to achieve a certain hair growth and anti-hair loss effect.

[0045] In some embodiments, the optical component 2 is assembled on the inner shell 12 so that the end 210 of the light source 21 of the optical component 2 can abut against the outer wall 121 of the inner shell 12, so that the loss of the output light of the light source 21 can be reduced when passing through the light-transmitting area 120.

[0046] In this embodiment, the optical component 2 is assembled on the inner shell 12 , and may not be connected to the outer shell 11 , that is, there may be an installation gap 130 between the optical component 2 and the outer shell 11 .

[0047] In other embodiments, the optical component 2 can be assembled with the outer shell 11, and the light source 21 is arranged toward the outer wall 121 of the inner shell 12, so that the light of the light source 21 can be emitted to the outside through the light-transmitting area 120 of the inner shell 12.

[0048] In addition, the inner shell 12 can be made of a transparent material, that is, the entire inner shell 12 is a light-transmitting area 120 , so as to adapt to the situation where the optical component 2 has multiple light sources 21 and facilitate the arrangement of the light sources 21 .

[0049] In some embodiments, Figures 2 to 6 As shown, in this embodiment, the front pad 30 is arranged on the inner side of the edge of the inner shell 12 or the outer shell 11, that is, on the inner side of the wearing piece 1. When the user 9 wears the wearing piece 1, the front pad 30 can fit with the head of the user 9 to achieve the purpose of blocking the outgoing light.

[0050] In the wearable optical device provided by the present invention, the front end refers to the end opposite to the face of the user 9 when in use, and similarly, the rear end refers to the end opposite to the back of the head of the user 9. Figure 3 , Figure 5 and Figure 6 As shown, the front pad 30 is arranged to protrude from the inner wall of the outer shell 11 or the inner shell 12. When the user 9 wears the wearable device 1, the front pad 30 can fit the forehead of the user 9 to block the outgoing light from irradiating the eyes of the user 9, thereby solving the problem of light leakage caused by poor wearing versatility of wearable optical devices and improving wearing safety.

[0051] Specifically, when in use, the light source 21 generates light, a portion of which is emitted through the light-transmitting area 120 on the inner shell 12 and irradiates the scalp area of ​​the user, and a series of optical phenomena such as refraction and diffuse reflection occur between the inner shell 12 and the scalp area of ​​the user 9. The light propagation path is as follows: Figure 6 As indicated by the middle dotted arrow, there is a possibility that some light will be emitted downward along the head, which may cause possible damage to the eyes. In order to avoid the possibility of light leakage, the front pad 30 is attached to the forehead so that the light emitted downward from the top of the head is absorbed and / or reflected by the front pad 30, thereby blocking the leakage of light and protecting the eyes of the user 9.

[0052] In some embodiments, Figure 7 and Figure 8 As shown, the two ends of the front pad 30 are respectively extended along the inner wall of the wearing piece 1 toward the rear end of the wearing piece 1. When in use, the front pad 30 can at least fit the face of the user 9 from the forehead to the temples on both sides to block the emitted light from irradiating the face of the user 9.

[0053] like Figure 7 and Figure 8As shown, the front pad 30 is arranged between the forehead and the temples on both sides, similar to a U-shape, and the two ends of the front pad 30 extend toward the temples on both sides respectively. When in use, the front pad 30 can at least completely fit the upper part of the face of the user 9 to completely block the outgoing light above the face, which is safer to use.

[0054] It is additionally noted that if Figure 2 and Figure 3 As shown, the edge of the outer shell 11 has an extended length segment relative to the edge of the inner shell 12, thereby forming an annular installation area. The front pad 30 is arranged in the installation area and abuts against the edge of the inner shell 12. At the same time, the front pad 30 is aligned with the edge of the outer shell 11. The front pad 30 is strip-shaped, which can reduce the contact area between the front pad 30 and the head and improve wearing comfort.

[0055] In some embodiments, the liner 3 is detachably connected to the wearing piece 1 to facilitate selective installation of the liner and to facilitate removal, cleaning or replacement of the liner.

[0056] In some embodiments, one of the pad 3 and the wearing piece 1 is provided with a first connecting portion, and the other is provided with a second connecting portion, and the first connecting portion and the second connecting portion are detachably connected, and the detachable connection method includes but is not limited to snap connection, buckle connection and tying (using laces to tie).

[0057] In one embodiment, one of the pad 3 and the wearing piece 1 is provided with a Velcro 33, and the other is provided with a Velcro mother patch 34, and the Velcro 33 is adaptively connected with the Velcro mother patch 34. Preferably, the Velcro 33 or Velcro mother patch 34 on the wearing piece 1 can be pre-installed in the installation area, and then the pad 3 is connected and installed according to the specific situation, so as to adapt to the specific head size of different users 9. Among them, the Velcro 33 or Velcro mother patch 34 on the wearing piece 1 can be a continuous and unified structure, or a segmented structure that is discontinuous or spaced, to ensure that the pad 3 can be set on the wearing piece 1 as needed.

[0058] In some embodiments, the pad 3 is an elastomer, which includes a first elastic member and a second elastic member. The first elastic member wraps the second elastic member therein, and the elastic modulus of the second elastic member is different from that of the first elastic member.

[0059] It can be understood that when the wearable optical device is in use, the pad 3 fits the head of the user 9 to prevent light from irradiating the eyes. Therefore, the pad 3 is set as an elastomer, which can improve the wearing comfort of the user 9 and has better light shielding performance. This embodiment adopts a solution in which the first elastic member wraps the second elastic member, and the elastic modulus of the second elastic member is greater than the elastic modulus of the first elastic member, so that the pad 3 can adapt to the head size differences of different users 9 while providing a better deformation shielding effect, thereby improving the versatility of the wearable member 1. The first elastic member has a smaller elastic modulus, so that the pad 3 has a good fit with the head and good light shielding performance; the second elastic member has a relatively large elastic modulus, which is conducive to the pad 3 to restore its shape in time when it is not worn, and is conducive to increasing the service life.

[0060] In some embodiments, the first elastic member is one or more combinations of cloth, leather, silicone, and rubber; the second elastic member is one or more combinations of foam and sponge.

[0061] Specifically, the pad 3 may be formed by wrapping sponge with cloth, or by wrapping foam with silica gel.

[0062] In some embodiments, Fig. 9 and Fig.10 As shown, the front pad 30 may be a split structure, and the front pad 30 includes a first part 301 and a second part 302, and the first part 301 and the second part 302 are spaced apart. When in use, the first part 301 and the second part 302 respectively correspond to the upper part of the left eye and the right eye of the user 9 and fit on the forehead of the user 9 to block the emitted light from irradiating the left eye and the right eye of the user 9.

[0063] like Fig. 9 and Fig.10 As shown, when in use, the wearable device 1 is worn on the head of the user 9, the first part 301 is located above the right eye and fits the forehead to block the outgoing light; the second part 302 is located above the left eye and fits the forehead to block the outgoing light. By providing a split front pad 30, it is convenient for different users 9 to adjust the positions of the first part 301 and the second part 302 on the wearable device 1 according to their own needs, so as to achieve a more suitable wearing method and better block the outgoing light.

[0064] The first part 301 and the second part 302 of the front pad 30 can be different elastic members and can have different lengths, which is not limited in this embodiment.

[0065] In some embodiments, Figure 7 and Fig. 9As shown, the pad 3 also includes a rear pad 31, which is arranged on the inner side of the rear end of the wearing piece 1. When in use, the rear pad 31 can at least fit the back area of ​​the user's 9 head to block the outgoing light.

[0066] like Figure 7 and Fig. 9 As shown, a front pad 30 is provided at the front end of the wearable component 1, and a rear pad 31 is provided at the rear end. The front pad 30 is used to block the emitted light from irradiating the eyes and causing harm to the user 9. The rear pad 31 fits with the back area of ​​the head of the user 9 when in use, which can block the emitted light. At the same time, it can also cooperate with the front pad 30 to adjust the distance between the wearable component 1 and the head of the user 9, so that the user 9 can set the rear pad 31 as needed according to the size of his own head. Among them, the rear pad 31 can be an integral elastic member arranged at the rear end, or it can be a plurality of elastic members arranged separately.

[0067] In some embodiments, the front pad 30 and the rear pad 31 are spaced apart and have a first gap 32. When in use, since the pad 3 has thickness, when the head of the user 9 is accommodated in the wearing space, there is also a second gap 14 between it and the wearing piece 1. The first gap 32 can connect the second gap 14 and the external environment, thereby achieving the effect of passive heat dissipation.

[0068] Specifically, if Figure 7 and Fig. 9 As shown, the front pad 30 is arranged at the front end of the wearing member 1, and the rear pad 31 is arranged at the rear end of the wearing member 1. The front pad 30 and the rear pad 31 form a first gap 32 at the rear part of the temples on both sides. When the user 9 wears the wearable optical device, Figure 5 As shown, when the head of the user 9 is accommodated in the wearing space, due to the thickness of the pad 3, there will be a gap between the head of the user 9 and the inner shell 12, that is, the shape and size of the head and the inner shell 12 are not completely consistent. Therefore, there is a second gap 14 after wearing. The second gap 14 is connected to the external environment through the first gap 32, which has a ventilation effect and is beneficial to the heat dissipation between the inner shell 12 and the head. At the same time, reducing the overall contact area of ​​the pad 3 with the head can reduce the use cost of the pad 3, and is beneficial to the flexible setting of the position of the pad 3 and the replacement of the pad 3, and has good versatility.

[0069] In addition, when the first part 301 and the second part 302 of the front liner 30 are arranged at intervals, the first part 301 and the second part 302 also have the first gap 32 between the forehead above the nose and the inner shell 12, so that the second gap 14 between the inner shell 12 and the head is connected to the external environment, which is conducive to heat dissipation and wearing. By providing multiple first gaps 32 in the circumferential direction of the wearing piece 1, it is conducive to forming a better ventilation effect.

[0070] In some embodiments, Fig.11 and Fig.12 As shown, the front pad 30 and the rear pad 31 are continuously arranged along the inner side of the opening edge of the wearing member 1 to form the pad 3 of the integral structure.

[0071] like Fig.11 and Fig.12 As shown, the pad 3 is an annular integrated structure, the portion of the pad 3 located at the front end of the wearing piece 1 is the front pad 30, and the portion located at the rear end of the wearing piece 1 is the rear pad 31. The front pad 30 and the rear pad 31 are unified and continuously formed into a pad 3, and the pad 3 is integrally installed on the inner side of the opening edge of the wearing piece 1. When in use, the pad 3 can fully block the outgoing light between the opening edge of the wearing piece 1 and the head, and can provide a continuous and uniform fit. Especially when the external ambient temperature is low, the continuous and uniform setting is conducive to the insulation between the inner shell 12 and the head.

[0072] It can be understood that the front pad 30 and the rear pad 31 can also be set as an integrated continuous structure at one end, and the other end abuts or has a smaller first gap 32 after installation, which is conducive to setting the pad 3 into a strip shape, suitable for wearable items 1 of any shape and size, and greatly improving versatility.

[0073] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
