[0031] Please see Figures 1 to 5 This application provides a sealed light-transmitting structure, including: a first shell 10, a second shell 20, a light-emitting component 40, and a light-transmitting sealing member 50. The first shell 10 has an opening 11, and the second shell 20 is disposed at the opening 11; the second shell 20 has a window 22. The light-transmitting sealing member 50 is annular and has a first side surface 50a and a second side surface 50b facing away from each other, combined with... Figure 6The first side 50a faces the first housing 10, and the second side 50b abuts against the second housing 20. The light-emitting assembly 40 includes a light guide 41, a point light emitter 42, and a circuit board 43. The circuit board 43 abuts against the first side 50a, and the point light emitter 42 is located on the side of the circuit board 43 facing the light-transmitting seal 50 and at the window 22. The light guide 41 and the second side 50b face each other. The light guide 41 has an incident surface 412a and an exit surface 411a, and the light-emitting surface 42a of the point light emitter 42 faces the incident surface 412a. The light emitted by the point light emitter 42 can pass through the light-transmitting seal 50, enter through the incident surface 412a, and exit through the exit surface 411a. Figures 4 to 6 The light-transmitting sealing element 50 has an outer ring bone 51 and an inner ring bone 52. The outer ring bone 51 is sandwiched between the edge of the opening 11 and the outer edge of the second shell 20, and the inner ring bone 52 is sandwiched between the circuit board 43 and the second shell 20.

[0032] The ring shape can be circular, elliptical, rectangular, rounded rectangle, etc. The shape of the light-transmitting seal 50 is compatible with the shapes of the second shell 20 and the circuit board 43.

[0033] The sealed light-transmitting structure provided in this embodiment has a second shell 20 disposed at the opening 11 of the first shell 10. An annular light-transmitting seal 50 is disposed between the first shell 10 and the second shell 20, and the light-transmitting seal 50 abuts against the second shell 20. The circuit board 43 in the light-emitting assembly 40 abuts against the first side 50a of the light-transmitting seal 50, and the light guide 41 is located on the second side 50b of the circuit board 43. The light emitted by the point light emitter 42 on the circuit board 43 can pass through the light-transmitting seal 50, enter through the incident surface 412a of the light guide 41, and exit through the exit surface 411a of the light guide 41, thus achieving light transmission outward. The light-transmitting sealing element 50 adopts a double-rib design. The outer ring rib 51 is sandwiched between the edge of the opening 11 of the first shell 10 and the outer edge of the second shell 20, and the inner ring rib 52 is sandwiched between the circuit board 43 and the second shell 20. This achieves a waterproof and dustproof seal between the first shell 10 and the second shell 20, and a waterproof and dustproof seal at the window 22 of the second shell 20. This protects the circuit board 43 and the point light-emitting element 42 and other internal components, meeting the requirements for outdoor use.

[0034] In some embodiments, please refer to Figure 3 , Figure 6 , Figure 7 After the first shell 10 and the second shell 20 are assembled, the inner cavity formed by the first shell 10 and the second shell 20 can hold predetermined components, such as the motherboard 90 and the battery 94. The battery 94 and the motherboard 90 are electrically connected to provide power. The first shell 10 and the second shell 20 can be connected by fasteners (such as screws), clips, etc.

[0035] For example, the first shell 10 and the second shell 20 can be opaque. The circuit board 43 and the point light-emitting element 42 are located inside the first shell 10 and the second shell 20. The light emitted by the point light-emitting element 42 can pass through the light-transmitting seal 50 and be conducted outward through the light guide 41.

[0036] In some embodiments, please refer to Figures 4 to 7 The point light-emitting element 42 can be a light-emitting diode (LED) lamp bead, which can be mounted on the circuit board 43 for easy assembly and control of multiple LED lamp beads. The circuit board 43 can be ring-shaped, and multiple point light-emitting elements 42 distributed in a ring can be mounted on the ring-shaped circuit board 43. The inner hole of the circuit board 43 can be used to arrange predetermined components (such as speakers), improving space utilization. Sound is output from the speaker, and light is emitted from the light-emitting component 40, resulting in a compact overall structure.

[0037] In some embodiments, please refer to Figures 4 to 8 The light guide 41 can be an optical resin component, such as polycarbonate (PC) or epoxy resin. When manufacturing the light guide 41, light diffusing powder can be added to the material of the light guide 41, and the light guide 41 with internally distributed light diffusing powder can be obtained through injection molding. For example, the light guide 41 is made of white, semi-transparent optical resin and light diffusing powder.

[0038] In some embodiments, please refer to Figures 4 to 6 , Figure 8 The light guide 41 includes an annular portion 411 and a plurality of reflective portions 412. The plurality of reflective portions 412 are arranged in a ring and connected to the annular portion 411. Each reflective portion 412 forms an incident surface 412a. The surface of the annular portion 411 forms an exit surface 411a, which extends along the ring. The light-emitting surfaces 42a of the plurality of point light emitters 42 are arranged facing the incident surfaces 412a of the plurality of reflective portions 412 respectively.

[0039] The light guide 41, employing an annular portion 411 and multiple reflectors 412, occupies a small space and has a compact structure. The point light source emitted by the point light emitter 42 enters the incident surface 412a of the corresponding reflector 412 and exits through the annular exit surface 411a, achieving full-circle light emission from the exit surface 411a. The shape of the annular portion 411, the arrangement of the multiple reflectors 412, and the arrangement of the multiple point light emitters 42 are compatible. The annular portion can be circular, elliptical, rectangular, or rounded rectangular, among other shapes.

[0040] In some embodiments, please refer to Figures 4 to 6 , Figure 8The light guide 41 is annular and has an incident surface 412a, a first reflecting surface 412b, a second reflecting surface 411b, and an exit surface 411a. The exit surface 411a extends along the annulus. The incident surface 412a and the first reflecting surface 412b are arranged sequentially outward along the radial direction of the light guide 41; the exit surface 411a and the second reflecting surface 411b are also arranged sequentially outward along the radial direction of the light guide 41. The first reflecting surface 412b and the second reflecting surface 411b are arranged facing each other along the axial direction of the light guide 41. Multiple point light emitters 42 are arranged in annularity, with their light-emitting surfaces 42a arranged outward along the radial direction of the light guide 41. The light emitted by the multiple point light emitters 42 is incident through the incident surface 412a, reflected sequentially by the first reflecting surface 412b and the second reflecting surface 411b, and then exits through the exit surface 411a. "Outward along the radial direction of the light guide 41" refers to the direction away from the center of the light guide 41 along its radial direction. Light diffusing powder is distributed inside the light guide 41. When light shines on the light diffusing powder, it will be refracted and scattered to diffuse the light in different directions, making the brightness of the light source more uniform and maintaining good light transmittance of the light guide 41.

[0041] The light guide 41 features a folded light path, enabling a longer light transmission distance within a limited space. The annular light guide 41, combined with multiple annularly arranged point light emitters 42, achieves uniform light emission from the annular exit surface 411a. Each point light emitter 42 emits a point light source within a certain angle range, which is incident on the incident surface 412a. The light is reflected by the first reflecting surface 412b and the second reflecting surface 411b, extending the light path distance within a small space. Combined with the light-diffusing powder within the light guide 41, the light is uniformly diffused, enhancing the light diffusion effect and transforming the point light source of the point light emitter 42 into a surface light source emitted from the exit surface 411a. The emitted light from two adjacent point light emitters 42 partially overlaps on the exit surface 411a, reducing the dark area between the emitted light from adjacent point light emitters 42 and achieving uniform light emission throughout the entire annularly extended exit surface 411a.

[0042] In some embodiments, see Figure 4 , Figure 5 , Figure 8 Both the first reflecting surface 412b and the second reflecting surface 411b are chamfered surfaces. The chamfered surfaces (first reflecting surface 412b and second reflecting surface 411b) can be the side of a frustum or an inclined surface (plane). This makes it easier to shape the light guide 41.

[0043] For example, the point light-emitting element 42 is an LED lamp bead. There are 10 point light-emitting elements 42 arranged in a circle or rounded rectangle, and each point light-emitting element 42 emits light from the side. The thickness of the light guide element 41 in the second direction A2 is 6 mm. The combination of multiple point light-emitting elements 42 with the light guide element 41 to which light-diffusing powder is distributed enables uniform light emission from the entire circumference of the light guide element 41's emission surface 411a.

[0044] In some embodiments, please refer to Figure 4 , Figure 8 The axial distribution of the point light-emitting element 42 and the light guide element 41 of the emission surface 411a enables the light-emitting assembly 40 to have a compact overall structure and occupy less space. This allows the light-emitting assembly 40 to be used in space-constrained scenarios, such as small electronic devices.

[0045] In some embodiments, please refer to Figure 4 , Figure 8 The surface of the annular portion 411 forms a second reflecting surface 411b and an exiting surface 411a, and each reflecting portion 412 forms an incident surface 412a and a first reflecting surface 412b. Figure 8 The point light source emitted by the point light emitter 42 enters the incident surface 412a of the corresponding reflector 412. When the light passes through the light diffusing powder inside the light guide 41, it is refracted and scattered, thus diffusing the light in different directions. It is reflected at the first reflecting surface 412b of the reflector 412, then reflected at the second reflecting surface 411b of the annular portion 411, and then uniformly emitted at the exit surface 411a.

[0046] In some embodiments, please refer to Figure 4 , Figure 8 The incident surface 412a and the first reflecting surface 412b are both planar, and the second reflecting surface 411b extends along a ring. This makes the light guide 41 easy to process. The light emitted by the point light emitting element 42 is reflected on the first reflecting surface 412b after passing through the incident surface 412a, and then reflected by the ring-shaped second reflecting surface 411b before finally exiting at the exit surface 411a.

[0047] In some embodiments, please refer to Figure 4 , Figure 8 The emitting surface 411a includes a first sub-emitting surface 411a1 and a second sub-emitting surface 411a2. The first sub-emitting surface 411a1 and the second reflecting surface 411b are arranged facing each other along the first direction A1. The second sub-emitting surface 411a2 is connected between the second reflecting surface 411b and the first sub-emitting surface 411a1. Light rays are emitted through the first sub-emitting surface 411a1 and the second sub-emitting surface 411a2, giving the light emitting assembly 40 a better light emission effect.

[0048] In some embodiments, please refer to Figure 4 , Figure 8 The thickness of the light guide 41 ranges from 5 mm to 10 mm. By setting the light guide 41 to a relatively small thickness, the point light source 42, combined with the light guide 41 containing light-diffusing powder, can convert the point light source of the point light source 42 into a surface light source output from the light guide 41. The overall structure is very thin and can be used in scenarios with limited space.

[0049] In some embodiments, please refer to Figures 4 to 6 , Figure 8 The light-transmitting sealing element 50 has multiple covers 53 protruding from the second side 50b, and multiple point light-emitting elements 42 are correspondingly disposed within the multiple covers 53. Multiple windows 22 are arranged in a ring, and multiple covers 53 are correspondingly located at the multiple windows 22, and multiple reflective parts 412 are correspondingly located at the multiple windows 22.

[0050] The cover 53 provides waterproof and dustproof sealing protection for the point light-emitting element 42, allowing the light emitted by the element to pass through the cover 53 and illuminate the reflective portion 412 of the light guide 41. The inner cavity of the cover 53 and the point light-emitting element 42 are shaped to match, for example, both are cuboid, allowing the point light-emitting element 42 to be housed within the cover 53 in a compact structure. The second shell 20 is provided with multiple windows 22, possessing high strength while also allowing light to pass through.

[0051] In some embodiments, please refer to Figure 4 , Figure 8 The second side 50b has multiple clearance grooves 54, and the multiple clearance grooves 54 and multiple cover portions 53 are arranged adjacent to each other in a one-to-one correspondence. The ends of multiple reflective portions 412 are located in the multiple clearance grooves 54 in a one-to-one correspondence. By placing the ends of the reflective portions 412 in the clearance grooves 54 of the light-transmitting seal 50, more light emitted by the point light-emitting element 42 can be irradiated onto the incident surface 412a of the reflective portion 412, and the thickness of the light-transmitting seal 50 is smaller, resulting in a compact structure.

[0052] In some embodiments, please refer to Figure 5 , Figure 6 , Figure 10 , Figure 11 The second shell 20 has an annular limiting groove 23, and the circuit board 43 is annular. The inner ring area 50c of the light-transmitting seal 50 and the circuit board 43 are stacked in the annular limiting groove 23. When assembling the light-transmitting seal 50 and the circuit board 43, the second side 50b of the light-transmitting seal 50 is placed against the second shell 20, the inner ring area 50c of the light-transmitting seal 50 is located in the annular limiting groove 23 of the second shell 20, and the circuit board 43 with the point light-emitting element 42 is placed against the first side 50a of the light-transmitting seal 50 and located in the annular limiting groove 23, which facilitates the positioning and assembly of the light-transmitting seal 50 and the circuit board 43 into the second shell 20.

[0053] In some embodiments, please refer to Figure 5 , Figure 10 , Figure 11The circuit board 43, the light-transmitting seal 50, and the second shell 20 are connected by fasteners 64 (such as screws). The fasteners 64 are sequentially inserted through the circuit board 43 and the light-transmitting seal 50 and threaded onto the second shell 20. Using fasteners to fix the circuit board 43 and the light-transmitting seal 50 to the second shell 20 makes assembly and disassembly easy, ensures reliable connection, and provides a good seal at the window 22 of the second shell 20.

[0054] For example, the circuit board 43, the light-transmitting seal 50, and the second shell 20 are connected by four fasteners 64, which are distributed circumferentially, and the structural connection is reliable.

[0055] In some embodiments, please refer to Figure 3 , Figure 5 , Figure 6 The outer edge of the second shell 20 has an annular groove 24, and the edge of the opening 11 has an annular boss 12. The outer ring bone 51 is located within the annular groove 24 and is sandwiched between the wall of the annular groove 24 and the annular boss 12. During assembly, the outer ring bone 51 is placed within the annular groove 24 of the second shell 20, and the annular boss 12 of the first shell 10 is pressed against the outer ring bone 51 to achieve a tight fit and effectively seal the first shell 10 and the second shell 20.

[0056] In some embodiments, please refer to Figures 4 to 6 The second shell 20 has an annular mating wall 25, and the light-transmitting sealing element 50 has an annular mating groove 55. The annular mating wall 25 is inserted into the annular mating groove 55, and the wall surface of the annular mating wall 25 abuts against the wall surface of the annular mating groove 55. During assembly, the annular mating groove 55 of the light-transmitting sealing element 50 and the annular mating wall 25 of the second shell 20 are inserted and mated, increasing the contact area between the light-transmitting sealing element 50 and the second shell 20 within a limited space, thereby improving the sealing and waterproofing effect.

[0057] In some embodiments, please refer to Figures 4 to 6 The light-transmitting seal 50 is made of silicone, thermoplastic polyurethane rubber, or thermoplastic elastomer. The aforementioned light-transmitting seal 50 possesses a certain degree of elastic deformation and light transmission capability, meeting the application requirements.

[0058] For example, the light-transmitting seal 50 can be a high-transmittance silicone component, with a transmittance of over 88%, providing good sealing, airtightness, and good stability, temperature resistance, and aging resistance due to the high purity of the silicone. The light-transmitting seal 50 adopts a double-rib design to achieve a waterproof and dustproof seal between the first shell 10 and the second shell 20, achieving IP67 waterproof rating.

[0059] Please see Figures 1 to 3This application provides an electronic device 100, including the aforementioned sealed and light-transmitting structure. Since this electronic device employs all the technical solutions of all the above embodiments, it also possesses all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0060] In some embodiments, please refer to Figures 1 to 5 The electronic device 100 includes a first side shell 31 and a second side shell 32. A second shell 20 is located at the opening 11 of the first shell 10, and the first shell 10 and the second shell 20 are connected by a plurality of first fasteners 61. The first side shell 31 has a first fastening portion 311 and a second fastening portion 312 distributed opposite to each other. The first fastening portion 311 fastens to the first shell 10, and the second fastening portion 312 fastens to the second shell 20. A portion of the first fasteners 61 are covered by the wall surface of the first side shell 31. A light guide 41 is located on the side of the second shell 20 away from the first shell 10, and the light guide 41 and the second shell 20 are connected by second fasteners 62, which are sequentially inserted through the second shell 20 and the light guide 41. The second side shell 32 is located on the first shell 10, and the second side shell 32 and the first shell 10 are connected by a third fastener 63. Another portion of the first fasteners 61 are covered by the wall surface of the second side shell 32.

[0061] The first fastener 61, the second fastener 62, and the third fastener 63 can be screws. The first fastener 61 can be sequentially inserted through the second housing 20 and the first housing 10 and threaded to the first housing 10, with its head abutting against the second housing 20. The second fastener 62 can be sequentially inserted through the second housing 20 and the light guide 41 and threaded to the light guide 41, with its head abutting against the bottom surface of the second housing 20.

The speaker 93 can be a waterproof speaker, installed at the opening 21 of the second shell 20. The inner edge of the light guide 41 has an annular baffle 415, and the mesh cover 80 is positioned between the annular baffle 415 and the second shell 20, so that the mesh cover 80 is limited to the second shell 20 along the thickness direction and will not fall out. The edge of the mesh cover 80 has a slot 81, and the light guide 41 has a locking arm 416 corresponding to the second side shell 32. The locking arm 416 engages with the slot 81 to limit the circumferential position of the mesh cover 80 and prevent the mesh cover 80 from rotating. The locking arm 416 can be connected to the extension arm 414.
