Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 and Figure 2 In one embodiment of the utility model application, an indicator light assembly 30 of a head-mounted device is disclosed, wherein the head-mounted device includes a first shell 10 and a second shell 20, a supporting bracket 11 is protrudingly provided on the outer wall of the first shell 10, the indicator light assembly 30 is arranged on the supporting bracket 11, and the second shell 20 is covered on the indicator light assembly 30 to shield the indicator light assembly 30; the indicator light assembly 30 includes a light-emitting component 31 and a light-guiding component 32, the light-emitting component 31 is arranged on the supporting bracket 11, and the light-emitting component 31 emits light in a direction toward the second shell 20; one end of the light-guiding component 32 is arranged above the light-emitting component 31, and the other end is bent and extended to the side of the supporting bracket 11 away from the first shell 10, for guiding the light emitted by the light-emitting component 31 in a direction away from the second shell 20.

[0029] The head-mounted device disclosed in this embodiment is a device worn on the user's head to realize functions. It can be a display device such as a virtual reality device, an augmented reality device, a mixed reality device, or a head massager, a head physiotherapy device, a head energy warehouse, and other functional devices. This embodiment only lists the types of head-mounted devices, not exhaustively. Other types of head-mounted devices, as equivalent replacements for the technical concepts in this embodiment, should also be within the scope of protection of this application.

[0030] The indicator light assembly 30 disclosed in this embodiment is used to transmit information by emitting optical signals to inform the user of the working status of the device. The device switch information can be transmitted by turning the indicator light on or off, or a multi-color indicator light can be used to transmit the information of the function mode switching by color change. Specifically, in this embodiment, the light-emitting element 31 is any one of a light-emitting diode light bar, an organic light-emitting diode light bar, an incandescent lamp, and a fluorescent lamp. The switch of an incandescent lamp can transmit the switch information of the device. The incandescent lamp has high brightness and long service life; and by using a red, blue or green light-emitting diode light bar, or an organic light-emitting diode light bar, the color of the indicator light can be increased to transmit more information.

[0031] In short, as long as it can transmit optical signals and inform the user of the working status of the device, other types of light-emitting components 31 may also be used. This embodiment is only an example and not an exhaustive list. As an equivalent replacement for the concept of the utility model, other types of light-emitting components 31 should also be within the scope of protection of this application as long as they can achieve the technical effects disclosed in this application.

[0032] Specifically, the light guide 32 disclosed in this embodiment is any one of an acrylic light guide plate, a polycarbonate light guide plate, and a microstructure light guide plate. The acrylic light guide plate is a common light guide plate, which is widely used in the field of lighting and display due to its good light transmission and cost-effectiveness. The polycarbonate light guide plate has excellent high temperature resistance and can be used for lighting and display equipment at higher temperatures; it has strong impact resistance, excellent shock resistance, is not easy to break and brittle; it is not easy to turn yellow or age, and can maintain a long service life. The microstructure light guide plate is a light guide plate that achieves uniform light transmission by engraving the surface of the microstructure. It has very high uniformity and light transmission efficiency, can achieve very uniform light distribution, and is suitable for occasions that require highly uniform lighting or display. According to the actual use scenario, a suitable type of light guide plate can be selected as the light guide 32. In this embodiment, only the type of light guide 32 is exemplified, but the protection scope of the utility model is not limited to this. As long as other types of light guides 32 can achieve the technical effects disclosed in this application, as an equivalent replacement of the concept of the utility model, they should also be within the scope of protection of this application.

[0033] Specifically, the indicator light assembly 30 disclosed in this embodiment is arranged on the supporting bracket 11 of the first shell 10, and is covered and protected by the second shell 20. The second shell 20 is a light-proof shell, which can be made of plastic material or metal material. When the head-mounted device is worn on the user's head, the first shell 10 is located at the bottom, the second shell 20 is located at the top, the light-emitting element 31 emits light to transmit the optical signal, and the light guide 32 guides the light emitted by the light-emitting element 31 in the direction away from the second shell 20, that is, downward. When the head-mounted device is worn, the user's eyes are located below the head-mounted device, so when the light path passes through the user's visual range, it is convenient for the user to intuitively observe the optical signal, so as to accurately judge the information given by the indicator light, which is conducive to improving the accuracy and convenience of the user's operation of the head-mounted device. In addition, the indicator light assembly 30 is shielded by the second shell 20, leaving only the light from the bottom, so that the indicator light can be prevented from emitting light upward or sideways, thereby avoiding light pollution.

[0034] like Figure 2 and Figure 3 As shown, as an implementation of this embodiment, it is disclosed that the supporting bracket 11 includes a platform portion 111, a first baffle 112 and a second baffle 113, and the platform portion 111 is protrudingly arranged on the outer wall of the first shell 10; the first baffle 112 is arranged on the platform portion 111, and is located on the side of the platform portion 111 away from the first shell 10; a receiving groove is formed between the first baffle 112 and the outer wall of the first shell 10, and the receiving groove is used to place the light-emitting component 31; the second baffle 113 is arranged on the platform portion 111, one end of the second baffle 113 is connected to the first shell 10, and the other end is connected to the first baffle 112; the second baffle 113 and the first baffle 112 are combined to form a supporting structure, and the supporting structure is used to support the light guide 32.

[0035] Specifically, in this embodiment, the position facing the user's face when the head-mounted device is worn is preferably set to the position where the support bracket 11 is set on the first shell 10, that is, the platform portion 111 is protruded and set at the corresponding user's forehead position, so as to facilitate the placement of the indicator light assembly 30. When the light is emitted downward, it can be directly emitted to the area in front of the user's eyes, which is convenient for the user to intuitively observe the indicator light signal. A first stop bar 112 is set on the platform portion 111 to form a receiving groove so that the reflector is placed on the platform portion 111 more stably, avoiding problems such as offset and sliding, thereby improving the stability of the device and helping to extend its service life.

[0036] Specifically, in this embodiment, the first baffle 112 and the second baffle 113 have different extension directions, and thus can form a cross support structure to support the light guide 32 and stabilize the light guide 32 above the accommodating groove, that is, to maintain a fixed distance between the light guide 32 and the light-emitting component 31 to reduce collision damage and achieve a better light transmission effect.

[0037] Specifically, in this embodiment, the first baffle 112 and the second baffle 113 can be integrally formed with the platform portion 111 to enhance the structural stability of the entire supporting bracket 11 and increase the mechanical properties of the supporting bracket 11 so as to stably support the indicator light assembly 30 .

[0038] like Figure 3 and Figure 4 As shown, as another implementation of the present embodiment, a bayonet 1131 is provided on the end of the second baffle 113 that contacts the first shell 10; the light guide member 32 includes a first light guide segment 321 and a second light guide segment 322, the first light guide segment 321 is provided on the supporting structure, and contacts the first baffle 112 and the second baffle 113; the second light guide segment 322 is connected to the first light guide segment 321, and is located on the side of the platform portion 111 away from the first shell 10; a limiting card strip 323 adapted to the bayonet 1131 is provided on the side of the first light guide segment 321 away from the second light guide segment 322.

[0039] In this embodiment, when the light guide 32 is set on the supporting structure, it is easy to slide horizontally. Therefore, a bayonet 1131 and a limiting strip 323 are set. The limiting strip 323 is constrained by the side wall of the bayonet 1131, so that the first light guide segment 321 cannot move horizontally, thereby maintaining the stability of the assembly state of the light guide 32.

[0040] Specifically, the first light guide segment 321 disclosed in the present embodiment is horizontally arranged on the supporting structure, and the second light guide segment 322 is vertically arranged on the side of the supporting bracket 11. When the light emitting component 31 emits light, the light is transmitted in the light guide component 32, and the light is refracted by the light guiding point in the light guide component 32 to change the propagation direction of the light and improve the uniformity of the emitted light beam, so that the light can finally be emitted uniformly downward, which can not only transmit optical information to the human eye, but also avoid the situation where the light intensity is too concentrated and damages the glasses.

[0041] For example Figure 3 and Figure 4As shown, as another implementation of the present embodiment, an elastic buckle 324 is provided on the side of the limiting clip 323 facing away from the first light guide segment 321, and a clip hole 1111 is provided on the platform portion 111 opposite to the elastic buckle 324; the elastic buckle 324 is inserted into the receiving groove and plugged into the clip hole 1111 to lock the light guide member 32.

[0042] In this embodiment, the light guide 32 needs to be stabilized on the supporting bracket 11 during use, so an elastic clip 324 is provided to cooperate with the clip hole 1111. During assembly, the light guide 32 is aligned with the clip hole 1111 of the platform portion 111 and pressed together so that the lateral protrusion at the front end of the elastic clip 324 is snapped onto the side of the platform portion 111 away from the light guide 32 to achieve a fixed connection. This assembly method is simple to operate and has a firm connection, which can keep the light guide 32 and the supporting bracket 11 connected as a whole, making it convenient for long-term use.

[0043] Specifically, as another implementation of this embodiment, it is disclosed that the elastic clip 324 is provided in plurality, and the plurality of elastic clips 324 are spaced apart along the length direction of the limiting clip strip 323; and the clip holes 1111 are provided in plurality, and the plurality of clip holes 1111 are spaced apart along the length direction of the accommodating groove.

[0044] The overall shape of the supporting bracket 11 disclosed in this embodiment is a long strip, so as to facilitate the assembly of the long strip light-emitting member 31 and the light-guiding member 32. The light-emitting member 31 and the light-guiding member 32 are set in a long strip, so as to facilitate the arrangement of multiple light sources along the length direction to emit a strip light beam, thereby covering the area directly in front of the user's head as much as possible, so that it is easier to be directly observed by the human eye, further improving the use efficiency of the indicator light, and facilitating the user to accurately identify the optical signal.

[0045] Specifically, the fixing of the elastic clip 324 is a point-to-point fixing method, so the fixing effect for the long strip of light guide 32 is limited. Multiple elastic clips 324 are provided, which match the multiple clip holes 1111 one by one. In this way, multi-point fixing along the length direction of the light guide 32 is beneficial to improve the stability of the light guide 32 and the supporting bracket 11.

[0046] like Figure 2 and Figure 3 As shown, as another implementation of this embodiment, it is disclosed that the supporting bracket 11 also includes a third baffle 114 and a fourth baffle 115, and the third baffle 114 and the fourth baffle 115 are both arranged on the platform portion 111; the third baffle 114 and the fourth baffle 115 are respectively located at the two ends of the first baffle 112; the third baffle 114 and the fourth baffle 115 are respectively in contact with the two sides of the light guide 32, so as to constrain the lateral movement of the light guide 32.

[0047] The light guide 32 disclosed in this embodiment is inserted into the receiving groove from top to bottom, so that the elastic buckle 324 is assembled and fixed with the clamping hole 1111. The third stopper 114 and the fourth stopper 115 arranged on both sides of the platform portion 111 are in contact with the side walls of the light guide 32, playing a restraining role, so that the light guide 32 remains fixed in the three-dimensional space and does not deviate in any direction, so as to achieve a stable and efficient light guiding effect.

[0048] Specifically, as another implementation of this embodiment, the platform portion 111, the first stop bar 112, the second stop bar 113, the third stop bar 114, and the fourth stop bar 115 are all integrally formed with the first shell 10. The integrally formed manufacturing method is simple to operate and has fewer processing steps, which is convenient for improving production efficiency; and the product has good mechanical properties, is not easy to be damaged, and is conducive to extending the service life.

[0049] like Figure 5 and Figure 6 As shown, as another implementation of this embodiment, a side of the inner wall of the second shell 20 facing the first shell 10 is provided with an avoidance groove 21, and the avoidance groove 21 is adapted to the light guide 32. The light guide 32 disclosed in this embodiment is fixed by the supporting bracket 11 on the side facing the first shell 10, and the side facing away from the first shell 10 is in contact with the second shell 20. The inner wall of the second shell 20 is adaptively provided with the avoidance groove 21 to avoid the light guide 32. At the same time, each side wall of the avoidance groove 21 can also further limit the light guide 32, thereby improving the stability of the light guide 32.

[0050] In summary, the present application discloses an indicator light assembly 30 of a head-mounted device, wherein the head-mounted device comprises a first shell 10 and a second shell 20, a support bracket 11 is protrudingly provided on the outer wall of the first shell 10, the indicator light assembly 30 is arranged on the support bracket 11, and the second shell 20 is covered on the indicator light assembly 30 to shield the indicator light assembly 30; the indicator light assembly 30 comprises a light-emitting member 31 and a light-guiding member 32, the light-emitting member 31 is arranged on the support bracket 11, and the light-emitting member 31 emits light in a direction toward the second shell 20; one end of the light-guiding member 32 is arranged above the light-emitting member 31, and the other end is bent and extended to the side of the support bracket 11 away from the first shell 10, and is used to guide the light emitted by the light-emitting member 31 in a direction away from the second shell 20. The indicator light assembly 30 disclosed in this embodiment is arranged on the support bracket 11 of the first shell 10, and is covered and protected by the second shell 20. When the head-mounted device is worn on the user's head, the first shell 10 is located at the bottom, the second shell 20 is located at the top, the light-emitting element 31 emits light to transmit optical signals, and the light guide 32 guides the light emitted by the light-emitting element 31 in a direction away from the second shell 20, that is, downward. The user's eyes are located below the head-mounted device, so when the light path passes through the user's visual range, it is convenient for the user to intuitively observe the optical signal, thereby accurately judging the information given by the indicator light, which is conducive to improving the accuracy and convenience of the user's operation of the head-mounted device. In addition, the indicator light assembly 30 is shielded by the second shell 20, leaving only the light from the bottom, so that the indicator light can be prevented from emitting light upward or to the side, avoiding light pollution.
