[0037] In the shell assembly structure 100 provided in the embodiment of the present application, the cover body 20 is arranged at the opening 11 of the housing 10 and connected by the first fastener 61.

The light guide 41 is fixed to the cover body 20 by the second fastener 62, and the second fastener 62 is sequentially arranged in the cover body 20 and the light guide 41. The second side shell 32 is connected to the housing 10 by the third fastener 63, and another part of the first fastener 61 is blocked by the second side shell 32. The shell assembly structure 100 can be disassembled for maintenance or replacement. The housing 10, the cover body 20 and the first side shell 31 are combined, and the structural connection is reliable and anti-breakage and disintegration, which is particularly suitable for outdoor use scenarios. Only the third fastener 63 can be seen on the appearance surface, and the first fastener 61 and the second fastener 62 cannot be seen.

[0038] Exemplarily, the housing 10 and the cover 20 may be connected by three first fasteners 61, and the plurality of first fasteners 61 are distributed around the circumference. The light guide 41 and the cover 20 may be connected by three second fasteners 62, and the plurality of second fasteners 62 are distributed around the circumference. The second side housing 32 and the housing 10 may be connected by two third fasteners 63, and the plurality of third fasteners 63 are distributed around the circumference. The overall structure is reliably connected.

[0039] In some embodiments, see Figure 6 , Figure 7 After the housing 10 and the cover 20 are assembled, the inner cavity enclosed by the housing 10 and the cover 20 can be used to place predetermined components, such as a motherboard 90, a battery 94, etc. The battery 94 is electrically connected to the motherboard 90 to provide power.

[0040] In some embodiments, see Figures 1 to 3 , Figure 6 , further comprising a decorative ring 70, the decorative ring 70 being disposed on the cover body 20, the decorative ring 70 covering the outer ring area 41a of the light guide 41, one end of the decorative ring 70 being embedded in the cover body 20 and the first side shell 31, and the decorative ring 70 being rotatably buckled on the light guide 41. The decorative ring 70 is disposed on the light guide 41, and serves to decorate the light guide 41. The outer ring area 41a of the light guide 41 is blocked by the decorative ring 70, and the remaining part can be used as a light exit area. One end of the decorative ring 70 is embedded and buckled on the cover body 20 and the first side shell 31, so that the decorative ring 70 is limited in the plane where the decorative ring 70 is located, and cannot be translated in the plane where the decorative ring 70 is located. The decorative ring 70 is rotatably buckled on the light guide 41, so that the decorative ring 70 is limited in the axial direction of the decorative ring 70. When the decorative ring 70 is fixed to the cover body 20 , the first side shell 31 can be securely fixed to the housing 10 and the cover body 20 , and the structure is interlocked layer by layer, the connection is reliable, and it is resistant to being broken or disassembled.

[0041] For example, see Figure 3The inner wall of the decorative ring 70 has a plurality of inner buckles 711 , and the outer periphery of the light guide 41 has a plurality of outer buckles 413 , and the outer buckles 413 and the inner buckles 711 are rotatably buckled in a one-to-one correspondence.

[0042] In some embodiments, see Figure 1 , Figure 2 , Figure 6 The first side shell 31 is roughly C-shaped, and the two ends of the first side shell 31 are bent inward to form a first buckle 311 and a second buckle 312. The first buckle 311 can be set as a deep buckle, and the second buckle 312 can be set as a shallow buckle. The length of the first buckle 311 is greater than the second buckle 312, so that the first buckle 311 can be reliably connected to the housing 10, meeting the connection reliability requirement, and the second buckle 312 is located for easy disassembly.

[0043] In some embodiments, see Figure 2 , Figure 3 The decorative ring 70 includes a major arc segment 71 and a connecting segment 72. The two ends of the major arc segment 71 are connected by the connecting segment 72. The wall surface of the second side shell 32 covers and abuts against the connecting segment 72. The two opposite side surfaces of the second side shell 32 and the two opposite end surfaces of the major arc segment 71 are arranged one by one to define the circumferential position of the decorative ring 70. Figure 7 The second side shell 32 is disposed against the connecting section 72 of the decorative ring 70 , and the second side shell 32 is fixed on the housing 10 , thereby fixing the decorative ring 70 on the housing 10 .

[0044] In some embodiments, see Figure 2 , Figure 3 , Figure 7 On the basis that the light guide 41 and the cover 20 are connected by the second fastener 62, the light guide 41 has an extension arm 414 corresponding to the second side shell 32, and a first fastener 61 is sequentially arranged through the extension arm 414, the cover 20 and the housing 10 and is threadedly connected to the housing 10, and the head of the first fastener 61 is arranged against the extension arm 414. The light guide 41 and the cover 20 are connected more reliably. The first fastener 61 is blocked by the second side shell 32 and cannot be seen from the appearance of the structure.

[0045] Exemplarily, the light guide 41 and the cover 20 may be connected via three second fasteners 62 and one first fastener 61 , and the connection is reliable.

[0046] In some embodiments, see Figures 3 to 6, and further includes a mesh cover 80, which is arranged at the mouth 21 of the cover body 20. The mesh cover 80 can be used to protect the speaker 93 at the mouth 21 of the cover body 20, and the sound emitted by the speaker 93 is transmitted outward through the mesh cover 80. The speaker 93 can be a waterproof speaker, which is installed at the mouth 21 of the cover body 20. The inner edge of the light guide 41 has an annular retaining wall 415, and the mesh cover 80 is limitedly installed between the annular retaining wall 415 and the cover body 20, so that the mesh cover 80 is limited on the cover body 20 along the thickness direction and will not fall out. The edge of the mesh cover 80 has a card slot 81, and the light guide 41 has a card arm 416 at the position corresponding to the second side shell 32. The card arm 416 is connected to the card slot 81 to limit the circumferential position of the mesh cover 80 so that the mesh cover 80 will not rotate. The card arm 416 can be connected to the extension arm 414.

[0047] In some embodiments, see Figures 4 to 6 The light guide 41 includes an annular portion 411 and multiple reflecting portions 412, and the multiple reflecting portions 412 are distributed in an annular shape and connected to the annular portion 411; each reflecting portion 412 forms an incident surface 412a; the surface of the annular portion 411 forms an exit surface 411a extending along the annular shape; the exit surface 411a extends along the annular shape; the cover body 20 has multiple windows 22 distributed in an annular shape, and the multiple reflecting portions 412 are located at the multiple windows 22 in a one-to-one correspondence; a circuit board 43 is provided on the inner wall of the cover body 20, and multiple point light-emitting members 42 are provided on the circuit board 43 in an annular shape, and the multiple point light-emitting members 42 are located at the multiple windows 22 in a one-to-one correspondence, and the light exit surfaces 42a of the multiple point light-emitting members 42 are arranged one-to-one toward the incident surfaces 412a of the multiple reflecting portions 412; the light emitted by the point light-emitting members 42 is incident from the incident surface 412a and emitted from the exit surface 411a.

[0048] The light guide 41, the point light emitting element 42 and the circuit board 43 constitute the light emitting component 40. The light guide 41 using the annular portion 411 and the multiple reflective portions 412 occupies a small space and has a compact structure. The point light source emitted by the point light emitting element 42 enters the incident surface 412a of the corresponding reflective portion 412 and can be emitted from the annular exit surface 411a, so that the exit surface 411a emits light in a whole circle. The shape of the annular portion 411, the arrangement position of the multiple reflective portions 412, and the arrangement position of the multiple point light emitting elements 42 are adapted to each other. The annular portion can be circular, elliptical, rectangular, rounded rectangular, and the like.

[0049] In some embodiments, see Figures 4 to 7The point light emitting element 42 may be a light emitting diode (LED) lamp bead, and the LED lamp bead may be arranged on the circuit board 43, which is convenient for assembling and controlling multiple LED lamp beads. The circuit board 43 may be annular, and multiple point light emitting elements 42 distributed in an annular shape may be installed on the annular circuit board 43. Predetermined components (such as a speaker) may be arranged at the inner hole position of the circuit board 43 to improve space utilization. The sound is outputted outwardly by the speaker, and the light is emitted outwardly by the light emitting component 40, and the overall structure is compact.

[0050] In some embodiments, see Figures 4 to 8 The light guide 41 may be an optical resin, such as polycarbonate (PC), epoxy resin, etc. When manufacturing the light guide 41, light diffusion powder may be added to the material of the light guide 41, and the light guide 41 with light diffusion powder distributed inside is obtained by injection molding. Exemplarily, the light guide 41 is made of white translucent optical resin and light diffusion powder.

[0051] In some embodiments, see Figures 4 to 6 , Figure 8 The light guide 41 is annular, and has an incident surface 412a, a first reflection surface 412b, a second reflection surface 411b and an exit surface 411a. The exit surface 411a extends along a ring. The incident surface 412a and the first reflection surface 412b are sequentially arranged outward along the radial direction of the light guide 41; the exit surface 411a and the second reflection surface 411b are sequentially arranged outward along the radial direction of the light guide 41. The first reflection surface 412b and the second reflection surface 411b are arranged facing each other along the axial direction of the light guide 41. A plurality of point light emitting elements 42 are distributed in annular shape, and the exit surfaces 42a of the point light emitting elements 42 are arranged outward along the radial direction of the light guide 41. The light emitted by the plurality of point light emitting elements 42 is incident from the incident surface 412a, and is sequentially reflected by the first reflection surface 412b and the second reflection surface 411b, and then exits from 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 the radial direction of the light guide 41. Light diffusing powder is distributed in the light guide 41. When light is irradiated by 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 the light guide 41 maintains good light transmittance.

[0052] The light guide 41 has a folded optical path, which can achieve a longer light transmission distance in a limited space. The annular light guide 41 combined with a plurality of point light emitters 42 arranged in an annular shape can achieve uniform light emission from the annular exit surface 411a. The point light emitters 42 emit a point light source within a certain angle range and are incident on the incident surface 412a. The light is reflected by the first reflection surface 412b and the second reflection surface 411b, which can extend the light path distance in a smaller space. The light diffusion powder in the light guide 41 is combined to diffuse the light evenly, increase the light diffusion effect, and convert the point light source of the point light emitter 42 into a surface light source emitted from the exit surface 411a. The emitted light formed by two adjacent point light emitters 42 on the exit surface 411a partially overlaps, reducing the dark area between the emitted light formed by the two adjacent point light emitters 42, and achieving uniform light emission of the entire circle of the annularly extended exit surface 411a.

[0053] In some embodiments, see Figure 4 , Figure 5 , Figure 8 The first reflecting surface 412b and the second reflecting surface 411b are both chamfered surfaces. The chamfered surfaces (the first reflecting surface 412b and the second reflecting surface 411b) can be truncated cone sides or inclined surfaces (planes), so that the light guide 41 can be easily formed.

[0054] Exemplarily, the point light emitting member 42 is an LED lamp bead. The number of the point light emitting members 42 is 10, and the point light emitting members 42 are arranged on a circle or a rounded rectangle, and the point light emitting members 42 use side light emission. The thickness of the light guide 41 in the second direction A2 is 6 mm. Multiple point light emitting members 42 combined with the light guide 41 distributed with light diffusion powder can achieve uniform light emission of the entire circle of the exit surface 411a of the light guide 41.

[0055] In some embodiments, see Figure 4 , Figure 8 , the axial distribution of the point light emitting element 42 and the light guide element 41 on the emission surface 411a. The overall structure of the light emitting assembly 40 can be compact and occupy less space. The light emitting assembly 40 can be applied in scenes with compact space, such as small electronic devices.

[0056] In some embodiments, see Figure 4 , Figure 8 The surface of the annular portion 411 forms a second reflection surface 411b and an emission surface 411a, and each reflection portion 412 forms an incident surface 412a and a first reflection surface 412b. Figure 8 The point light source emitted by the point light emitting element 42 enters the incident surface 412a of the corresponding reflective portion 412, and the light is refracted and scattered when passing through the light diffusion powder inside the light guide 41, so that the light is diffused in different directions. It is reflected on the first reflective surface 412b of the reflective portion 412, and then reflected on the second reflective surface 411b of the annular portion 411 and uniformly emitted from the emission surface 411a.

[0057] In some embodiments, see Figure 4 , Figure 8 The incident surface 412a and the first reflecting surface 412b are both planes, and the second reflecting surface 411b extends in a ring shape. This makes it easy to process the light guide 41. The light emitted by the point light emitting element 42 can be reflected on the first reflecting surface 412b after passing through the incident surface 412a, and then reflected by the annular second reflecting surface 411b, and finally emitted from the emitting surface 411a.

[0058] In some embodiments, see 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. The light emitting component 40 has a better light emitting effect by emitting light through the first sub-emitting surface 411a1 and the second sub-emitting surface 411a2.

[0059] In some embodiments, see Figure 4 , Figure 8 , the thickness range of the light guide 41 is [5 mm, 10 mm]. When the light guide 41 is set to a smaller thickness, the point light emitting member 42 is combined with the light guide 41 with light diffusion powder distributed thereon, and the point light source of the point light emitting member 42 can be converted into a surface light source output from the light guide 41. The overall structure is very thin and can be applied in scenes with compact space.
