Today, wearable wristbands have evolved into smart or specialized electronic devices, offering capabilities such as physiological monitoring and connectivity with external electronic devices, thereby enhancing convenience. Furthermore, wristband accessories are gradually integrating with current technology, evolving into new types of wearable wristbands. However, existing wearable wristband devices lack a suitable hinge module that allows for integrated, extended space within the housing for optical components. Therefore, designing a wearable wristband with both luminous functionality and a well-defined extended space has been a key goal in this field.

The present invention provides a wearable light-emitting device that can be quickly donned by the user. The device also includes a rotating shaft module in the middle of the body that rotates about a virtual axis on the outer side of the housing. This allows the body to be designed with a hollow structure that allows the optical element to fully extend.

The present invention provides a wearable light-emitting device, comprising an inner shell module, an outer shell module, a light-emitting unit, and a light-guiding element. The outer shell module is connected to the inner shell module to form a first body, a second body, and a storage space between the inner shell module and the outer shell module. The first body includes a guide groove structure. The guide groove structure includes a guide groove. The opposite ends of the guide groove are respectively defined as a first position and a second position. The second body includes a protrusion and a guide post.

The light-emitting unit is disposed in the storage space for providing a light beam. The light-guiding element is disposed in the storage space to cover the light-emitting unit. When the wearable light-emitting device switches to the expanded state, the guide post slides to the first position of the guide groove, and the second body rotates away from the first body about the virtual axis. When the wearable light-emitting device switches to the closed state, the guide post slides to the second position of the guide groove, and the second body rotates about the virtual axis to abut the first body.

In one embodiment of the present invention, the first and second bodies have a first and second mating end surfaces, respectively. When switched to the expanded state, the first and second mating end surfaces form an angle. When switched to the closed state, the first mating end surface abuts the second mating end surface.

In one embodiment of the present invention, the guide slot includes a positioning portion. When switched to the closed state, the guide post slides past the positioning portion to slide to the second position of the guide slot.

In one embodiment of the present invention, the inner housing module includes a plurality of card slots, and the outer housing module includes a plurality of card blocks, and the plurality of card blocks are engaged with the plurality of card slots.

In one embodiment of the present invention, the wearable light-emitting device further includes a light-transmitting element disposed on the light-guiding element. The housing module includes a plurality of enclosed hollow areas. The light-transmitting element includes a plurality of protrusions. The plurality of protrusions extend into the plurality of enclosed hollow areas.

In one embodiment of the present invention, the wearable light-emitting device is spiral-shaped. When worn, the end of the first body away from the virtual axis is not connected to the end of the second body away from the virtual axis.

Based on the above, the wearable light-emitting device of the present invention includes an inner housing module, an outer housing module, a light-emitting unit, and a light-guiding element. The first body includes a guide groove structure. The guide groove structure includes a guide groove. Opposite ends of the guide groove are defined as a first position and a second position, respectively. A guide post of the second body is positioned within the guide groove. When the wearable light-emitting device is switched to an expanded state, the guide post slides to the first position within the guide groove, causing the second body to rotate about the virtual axis away from the first body. When the wearable light-emitting device is switched to a closed state, the guide post slides to the second position within the guide groove, causing the second body to rotate about the virtual axis and abut against the first body. In this way, the wearable light-emitting device can be provided with a hinge module in the middle section of the body that rotates about a virtual axis outside the housing, allowing the user to quickly put it on. Furthermore, the wearable light-emitting device can be designed with a hollow structure within the body to allow the optical element to fully extend, thereby enhancing the optical effect of the wearable light-emitting device. It is also worth noting that since the hinge module is designed in the middle section of the wearable light-emitting device, the overall design can be further spiraled, thereby enhancing the visual effect. This patent has the technical effects of light guidance, waterproofness, and quick assembly and disassembly.

To make the above features and advantages of the present invention more clearly understood, the following examples are given and described in detail with reference to the accompanying drawings.

Figures 2A and 2B are schematic front views of the wearable lighting device of Figures 1A and 1B in their unfolded and closed states, respectively. Figure 3 is a schematic top view of the wearable lighting device of Figure 1B. Please refer to Figures 1A to 3. This embodiment provides a wearable lighting device 100, such as a smart bracelet or other functional bracelet. However, the present invention is not limited to the type of wearable lighting device 100. The wearable lighting device 100 is a non-ring-type wearable device, as shown in Figures 1B and 3.

The wearable light-emitting device 100 includes a first body 200 and a second body 300 connected to each other. Therefore, when donning or doffing the wearable light-emitting device 100, the first body 200 and the second body 300 can be deployed in an extended state by the movement of the guide groove structure 210 and the protrusion 310, as shown in Figures 1A and 2A . Alternatively, the first body 200 and the second body 300 can be deployed in a closed state by the movement of the guide groove structure 210 and the protrusion 310, as shown in Figures 1B , 2B , and 3 . Specifically, the first body 200 and the second body 300 rotate about a virtual axis C to adopt an deployed or closed state. The virtual axis C is located at the junction of the first body 200 and the second body 300 on the side facing the outer housing module 120 (see Figures 6A and 6B). It is worth noting that when the wearable light-emitting device 100 is in a closed state, in a direction parallel to the annular center axis, the wearable light-emitting device 100 presents a partially overlapping annular structure, as shown in Figure 2B. In a direction perpendicular to the annular center axis, the wearable light-emitting device 100 presents a spiral structure, as shown in Figure 3. In other words, when worn, the opposite ends of the wearable light-emitting device 100 are not connected. As shown in Figures 1A and 2A, when the wearable light-emitting device 100 is in the unfolded state, the wearable light-emitting device 100 presents a non-overlapping ring structure in a direction parallel to the ring center axis A, and the opposite ends of the wearable light-emitting device 100 are not connected.

Figures 4A and 4B are three-dimensional exploded views of the wearable light-emitting device of Figures 1A and 1B in their expanded and closed states, respectively. Figure 5 is a cross-sectional view of the wearable light-emitting device of Figure 1A. Please refer to Figures 4A to 5. In this embodiment, the wearable light-emitting device 100 includes an inner housing module 110, an outer housing module 120, a light-emitting unit 130, and a light-guiding element 140. The inner housing module 110 serves as the inward-facing housing of the wearable light-emitting device 100, while the outer housing module 120 serves as the outward-facing housing of the wearable light-emitting device 100. The inner housing module 110 and the outer housing module 120 are connected to form a first body 200, a second body 300, and an accommodating space E (as shown in FIG. 5 ) between the inner housing module 110 and the outer housing module 120 for accommodating the light-emitting unit 130 and the light-guiding element 140. Specifically, in this embodiment, the inner housing module 110 includes a first inner housing 112 and a second inner housing 114, and the outer housing module 120 includes a first outer housing 122 and a second outer housing 124. The first inner housing 112 of the inner housing module 110 and the first outer housing 122 of the outer housing module 120 are combined to form a first body 200, while the second inner housing 114 of the inner housing module 110 and the second outer housing 124 of the outer housing module 120 are combined to form a second body 300.

In this embodiment, the inner housing module 110 further includes a plurality of slots 116, and the outer housing module 120 includes a plurality of latches 126. The latches 126 of the outer housing module 120 engage with the slots 116 of the inner housing module 110, as shown in FIG5 . The present invention is not limited to the type and shape of the slots 116 and the latches 126. In a preferred embodiment, the inner side of the outer housing module 120 may be designed to have reflective properties, but the present invention is not limited to this.

The light-emitting unit 130 is disposed in the housing space E formed by the connection between the inner and outer housing modules 110 and 120, and is used to provide a light beam L. In this embodiment, the light-emitting unit 130 is, for example, a light strip composed of multiple light-emitting diodes. The light-emitting diodes can be single-wavelength or multi-wavelength, but the present invention is not limited thereto. The light-guiding element 140 is disposed in the housing space E formed by the connection between the inner and outer housing modules 110 and 120, with the light-emitting unit 130 positioned between the inner and outer housing modules 110 and the light-guiding element 140. The light-guiding element 140 is, for example, a light-guiding strip, disposed parallel to and in contact with the light-emitting unit 130. Therefore, when the light-emitting unit 130 is activated to provide the light beam L, the light beam L is transmitted from the side of the light guide element 140 adjacent to the inner housing module 110 toward the side adjacent to the outer housing module 120, and is emitted from the side of the light guide element 140 adjacent to the outer housing module 120.

In this embodiment, the wearable light-emitting device 100 further includes a light-transmitting element 160 disposed on the light-guiding element 140 for transmitting the light beam L therethrough. Specifically, in this embodiment, the housing module 120 includes a plurality of concave spaces 128, and the light-transmitting element 160 includes a plurality of protrusions 162 extending into the concave spaces 128 of the housing module 120, thereby achieving the visual effect of the light beam L being transmitted through the housing. In other words, the shape of the protrusions 162 of the light-transmitting element 160 is adapted to the shape of the concave spaces 128 of the housing module 120. The present invention does not limit the size, shape, or distribution of the protrusions 162 and the concave spaces 128. In one embodiment, the plurality of protrusions 162 may be added with optical microstructures having a light-uniforming effect to further enhance the overall light-uniforming effect, but the present invention is not limited thereto.

Figures 6A and 6B are schematic front views of a portion of the wearable light-emitting device of Figures 1A and 1B in the expanded and closed states, respectively. Figures 7A and 7B are schematic perspective views of a portion of the wearable light-emitting device of Figures 1A and 1B in the expanded and closed states, respectively. Please refer to Figures 4A, 4B, and Figures 6A to 7B. The first body 200 includes a guide groove structure 210, which includes a plurality of guide grooves 212. The second body 300 includes a protrusion 310 and a plurality of guide posts 320. In this embodiment, the first inner housing 112 of the inner housing module 110 includes a first guide groove structure 210_1, and the first outer housing 122 of the outer housing module 120 includes a second guide groove structure 210_2. The first guide groove structure 210_1 and the second guide groove structure 210_2 form the guide groove structure 210. Furthermore, in this embodiment, the protrusion 310 extends from the second inner housing 114 of the inner housing module 110, but the present invention is not limited to this.

The protrusion 310 of the second body 300 extends into the first body 200, and the guide post 320 of the second body 300 is located in the guide groove 212 of the first body 200. In other words, the guide post 320 of the second body 300 is coupled to the guide groove 212 of the first body 200. The opposite ends of the guide groove 212 of the guide groove structure 210 are defined as a first position A1 and a second position A2, respectively. The guide post 320 of the second body 300 is used to slide between the first position A1 and the second position A2 in the guide groove 212 to switch between states. Therefore, when the guide post 320 of the second body 300 slides to the first position A1 of the guide groove 212 of the first body 200, the wearable light-emitting device 100 switches to the expanded state, and the second body 300 rotates about the virtual axis C away from the first body 200. When the guide post 320 of the second body 300 slides to the second position A2 of the guide groove 212 of the first body 200, the wearable light-emitting device 100 switches to the closed state, and the second body 300 rotates about the virtual axis C to abut the first body 200. In this way, the wearable light-emitting device 100 can be provided with a hinge module in the middle section of the body that rotates about a virtual axis C on the outer side of the housing, enabling users to quickly put the device on. Furthermore, the wearable light-emitting device 100 can be designed with a hollow structure within the body to allow the optical components to fully extend, thereby enhancing the optical performance of the wearable light-emitting device 100. It is also worth noting that since the hinge module of this embodiment is designed in the middle section of the wearable light-emitting device 100, the overall design can be further spiraled, thereby enhancing the visual appeal of the device.

Specifically, the first body 200 and the second body 300 have a first joining surface S1 and a second joining surface S2, respectively. When the wearable light-emitting device 100 is in the expanded state, the first joining surface S1 and the second joining surface S2 form an angle. When the wearable light-emitting device 100 is in the closed state, the first joining surface S1 abuts against the second joining surface S2. In this embodiment, the wearable light-emitting device 100 further includes a waterproof member 150 disposed in the accommodating space E on the side of the first body 200 facing the first joining surface S1. Specifically, the protrusion 310 of the second body 300 includes an annular groove 312. When the wearable light-emitting device 100 is in the closed state, the waterproof member 150 is disposed in the annular groove 312. This prevents moisture from entering the interior of the first body 200. Furthermore, in this embodiment, the guide groove 212 of the guide groove structure 210 includes multiple positioning portions 214. Specifically, the positioning portions 214 are indentations on either side of the guide groove 212. The distance between the indentations is slightly smaller than the diameter of the guide post 320, thereby providing a locking and positioning effect. Therefore, when the wearable light-emitting device 100 switches to the closed state, the guide post 320 slides past the positioning portions 214 of the guide groove 212 to the second position A2 of the guide groove 212. This improves the stability of maintaining the closed state.

Figures 8A and 8B are exploded 3D views of a wearable light-emitting device according to another embodiment in its expanded and closed states, respectively. Figures 9A and 9B are front views of portions of the wearable light-emitting device of Figures 8A and 8B in their expanded and closed states, respectively. Figures 10A and 10B are 3D views of portions of the wearable light-emitting device of Figures 8A and 8B in their expanded and closed states, respectively. The wearable light-emitting device 100A shown in this embodiment is similar to the wearable light-emitting device 100 shown in Figures 1A and 1B . The difference between the two is that, in this embodiment, the guide groove structure 210A of the first body 200 further includes a plurality of grooves 222, a plurality of positioning bumps 224, and a plurality of elastic elements 226. Furthermore, the protrusion 310A of the second body 300 includes a plurality of positioning grooves 314. A positioning bump 224 is embedded in the groove 222. A resilient element 226 is connected to one end of the positioning bump 224. Specifically, one end of the positioning bump 224 has a support structure for mounting the resilient element 226, while the other end of the positioning bump 224 has a protrusion structure that fits into the positioning groove 314 of the protrusion 310A. Therefore, when the wearable light-emitting device 100A is switched to the closed state, the other end of the positioning bump 224 of the guide groove structure 210A is moved into the positioning groove 314 of the protrusion 310A via the resilient element 226. In this way, the wearable light-emitting device 100A can be provided with a hinge module in the middle section of the body that rotates about a virtual axis C on the outer side of the housing, allowing the user to quickly put the device on. Furthermore, the wearable light-emitting device 100A can be designed with a hollow structure within the body to allow the optical element to fully extend, thereby enhancing the optical effect of the wearable light-emitting device 100A.

On the other hand, in this embodiment, the wearable light-emitting device 100A further includes a housing connector 170 (as shown in Figures 8A and 8B ), which connects the first inner housing 112 of the inner housing module 110 to the second outer housing 124 of the outer housing module 120, and connects the second inner housing 114 of the inner housing module 110 to the first outer housing 122 of the outer housing module 120, to enhance structural strength. The housing connector 170 of this embodiment can also be applied to other embodiments, such as the wearable light-emitting device 100 of Figure 1A , and the present invention is not limited thereto.

In summary, the wearable light-emitting device of the present invention includes an inner housing module, an outer housing module, a light-emitting unit, and a light-guiding element. The first body includes a guide groove structure. The guide groove structure includes a guide groove. Opposite ends of the guide groove are defined as a first position and a second position, respectively. A guide post of the second body is positioned within the guide groove. When the wearable light-emitting device is switched to an expanded state, the guide post slides to the first position within the guide groove, causing the second body to rotate about a virtual axis away from the first body. When the wearable light-emitting device is switched to a closed state, the guide post slides to the second position within the guide groove, causing the second body to rotate about the virtual axis and abut against the first body. In this way, the wearable light-emitting device can be provided with a hinge module in the middle section of the body that rotates about a virtual axis on the outer side of the housing, making it easier for the user to put the device on. Furthermore, the wearable light-emitting device can be designed with a hollow structure within the body to allow the optical element to fully extend, thereby enhancing the optical effect of the wearable light-emitting device. It is also worth noting that since the hinge module is designed in the middle section of the wearable light-emitting device, the overall design can be further spiraled, thereby enhancing the visual effect.

Although the present invention has been disclosed above through embodiments, they are not intended to limit the present invention. Anyone with ordinary skill in the art may make minor modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the attached patent application.
