[0037] The shell assembly structure 100 provided by the embodiment of the present application, the cover 20 is arranged at the opening 11 of the shell 10 and is connected through the first fastener 61. The first buckle part 311 of the first side shell 31 is buckled to the shell 10, the second buckle part 312 is buckled to the cover 20, and a part of the first fastener 61 is shielded by the first side shell 31. The light guide piece 41 is fixed on the cover 20 through the second fastener 62, and the second fastener 62 is sequentially arranged on the cover 20 and the light guide piece 41. The second side shell 32 is connected to the shell 10 through the third fastener 63, and the other part of the first fastener 61 is shielded by the second side shell 32. The shell assembly structure 100 can be disassembled for maintenance or replacement. The shell 10, the cover 20 and the first side shell 31 are combined, the structural connection is reliable, and the disintegration caused by falling is prevented. It is especially suitable for outdoor use scenarios. The appearance surface only sees the third fastener 63, and the first fastener 61 and the second fastener 62 cannot be seen.

[0038] For example, the shell 10 and the cover 20 can be connected through three first fasteners 61, and a plurality of first fasteners 61 are distributed around the circumference. The light guide piece 41 and the cover 20 can be connected through three second fasteners 62, and a plurality of second fasteners 62 are distributed around the circumference. The second side shell 32 and the shell 10 can be connected through two third fasteners 63, and a plurality of third fasteners 63 are distributed around the circumference. The overall structural connection is reliable.

[0039] In some embodiments, referring to Figure 6 , Figure 7 After the shell 10 and the cover 20 are assembled, the inner cavity surrounded by the shell 10 and the cover 20 can place predetermined components, such as the mainboard 90, the battery 94, etc. The battery 94 and the mainboard 90 are electrically connected to provide power.

[0040] In some embodiments, referring to Figures 1 to 3 , Figure 6 Further comprising a decorative ring 70, the decorative ring 70 is arranged on the cover 20, the decorative ring 70 covers the outer ring area 41a of the light guide piece 41, one end of the decorative ring 70 is embedded in the cover 20 and the first side shell 31, and the decorative ring 70 is rotationally buckled to the light guide piece 41. The decorative ring 70 is arranged on the light guide piece 41 and plays a decorative role for the light guide piece 41. The outer ring area 41a of the light guide piece 41 is shielded by the decorative ring 70, and the remaining part can serve as a light emitting area. One end of the decorative ring 70 is embedded and buckled on the cover 20 and the first side shell 31, so as to limit the decorative ring 70 in the plane where the decorative ring 70 is located, and the decorative ring 70 cannot be translated in the plane where the decorative ring 70 is located. The decorative ring 70 is rotationally buckled to the light guide piece 41, so as to limit the decorative ring 70 in the axial direction of the decorative ring 70. In the case that the decorative ring 70 is fixed on the cover 20, the first side shell 31 can be reliably fixed on the shell 10 and the cover 20, and the structure is interlocked layer by layer, the connection is reliable, and the disintegration caused by falling is prevented.

[0041] For example, referring to 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, which are one-to-one rotationally buckled.

[0042] In some embodiments, referring to Figure 1 、 Figure 2 、 Figure 6 The first side shell 31 is substantially C-shaped, and the two ends of the first side shell 31 are inwardly bent to form a first buckle portion 311 and a second buckle portion 312. The first buckle portion 311 can be a deep buckle, and the second buckle portion 312 can be a shallow buckle. The length of the first buckle portion 311 is greater than that of the second buckle portion 312, so that the first buckle portion 311 can be reliably connected to the case 10, meeting the reliable connection requirement, and the second buckle portion 312 is easily disassembled.

[0043] In some embodiments, referring to Figure 2 、 Figure 3 The decorative ring 70 includes an arc segment 71 and a connecting segment 72, and the two ends of the 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 opposite two side surfaces of the second side shell 32 and the opposite two end surfaces of the arc segment 71 are arranged one-to-one opposite to each other to limit the circumferential position of the decorative ring 70. In combination with Figure 7 The second side shell 32 abuts against the connecting segment 72 of the decorative ring 70, and the second side shell 32 is fixed to the case 10, thereby fixing the decorative ring 70 to the case 10.

[0044] In some embodiments, referring to Figure 2 、 Figure 3 、 Figure 7 On the basis of being connected by the second fasteners 62 between the light guide 41 and the cover 20, the light guide 41 has an extension arm 414 corresponding to the second side shell 32. One of the first fasteners 61 is sequentially arranged in the extension arm 414, the cover 20 and the case 10 and is threadedly connected to the case 10, and the head of the first fastener 61 abuts against the extension arm 414. The light guide 41 and the cover 20 are more reliably connected. The first fastener 61 is shielded by the second side shell 32, and cannot be seen from the structure appearance surface.

[0045] For example, the light guide 41 and the cover 20 can be connected by three second fasteners 62 and one first fastener 61, and the connection is reliable.

[0046] In some embodiments, referring to Figures 3 to 6The net cover 80 is arranged at the opening 21 of the cover body 20, and can be used to protect the speaker 93 at the opening 21 of the cover body 20. The sound emitted by the speaker 93 can be transmitted outward through the net cover 80. The speaker 93 can be a waterproof speaker, and is arranged at the opening 21 of the cover body 20. The inner edge of the light guide 41 has an annular blocking wall 415. The net cover 80 is limitedly arranged between the annular blocking wall 415 and the cover body 20, so that the net cover 80 is limitedly arranged on the cover body 20 in the thickness direction and cannot be taken out. The edge of the net cover 80 has a clamping groove 81, and the light guide 41 corresponds to the second side shell 32 and has a clamping arm 416. The clamping arm 416 is clamped in the clamping groove 81, so as to limit the circumferential position of the net cover 80, and the net cover 80 cannot be rotated. The clamping arm 416 can be connected to the extension arm 414.

[0047] In some embodiments, referring to Figures 4 to 6 The light guide 41 includes an annular portion 411 and a plurality of reflecting portions 412. The plurality of reflecting portions 412 are annularly distributed 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 cover body 20 has a plurality of windows 22 annularly distributed. The plurality of reflecting portions 412 are one-to-one corresponding to the plurality of windows 22. The inner wall of the cover body 20 is provided with a circuit board 43. The circuit board 43 has a plurality of point light emitting elements 42 annularly arranged thereon. The plurality of point light emitting elements 42 are one-to-one corresponding to the plurality of windows 22. The light emitting surface 42a of the plurality of point light emitting elements 42 is one-to-one corresponding to the incident surface 412a of the plurality of reflecting portions 412. The light emitted by the point light emitting element 42 is incident on the incident surface 412a and is emitted from the exit surface 411a.

[0048] The light guide 41, the point light emitting element 42 and the circuit board 43 constitute a light emitting assembly 40. The light guide 41 with the annular portion 411 and the plurality of reflecting portions 412 occupies a small space and has a compact structure. The point light emitted by the point light emitting element 42 enters the incident surface 412a of the corresponding reflecting portion 412 and is emitted from the annular exit surface 411a, so as to realize the whole-circle light emission of the exit surface 411a. The shape of the annular portion 411, the arrangement position of the plurality of reflecting portions 412 and the arrangement position of the plurality of point light emitting elements 42 are matched. The annular portion can be circular, elliptical, rectangular, round rectangular or the like.

[0049] In some embodiments, referring to Figures 4 to 7The point light emitting member 42 can be a light emitting diode (LED) lamp bead. The LED lamp bead can be arranged on the circuit board 43, facilitating assembly and control of multiple LED lamp beads. The circuit board 43 can have a ring shape. The multiple point light emitting members 42 arranged in a ring shape can be mounted on the ring-shaped circuit board 43. A predetermined component (such as a loudspeaker) can be arranged at a position of the inner hole of the circuit board 43, improving space utilization. The loudspeaker outputs sound outward, and the light emitting assembly 40 outputs light outward. The overall structure is compact.

[0050] In some embodiments, referring to Figures 4 to 8 The light guide member 41 can be an optical resin member, such as polycarbonate (PC), epoxy resin, or the like. When the light guide member 41 is manufactured, light diffusion powder can be added to the material of the light guide member 41. The light guide member 41 with the light diffusion powder distributed inside can be obtained by injection molding. For example, the light guide member 41 is made of white translucent optical resin and light diffusion powder.

[0051] In some embodiments, referring to Figures 4 to 6 、 Figure 8 The light guide member 41 has a ring shape. The light guide member 41 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 ring shape. The incident surface 412a and the first reflecting surface 412b are arranged in sequence along the radial direction of the light guide member 41 outward. The exit surface 411a and the second reflecting surface 411b are arranged in sequence along the radial direction of the light guide member 41 outward. The first reflecting surface 412b and the second reflecting surface 411b are arranged to face each other along the axial direction of the light guide member 41. The multiple point light emitting members 42 are arranged in a ring shape. The light emitting surface 42a of the point light emitting member 42 is arranged along the radial direction of the light guide member 41 outward. The light emitted by the multiple point light emitting members 42 is incident on the incident surface 412a, and is reflected by the first reflecting surface 412b and the second reflecting surface 411b in sequence before being emitted by the exit surface 411a. The radial direction outward of the light guide member 41 refers to a direction away from the center of the light guide member 41 along the radial direction of the light guide member 41. The light guide member 41 has light diffusion powder distributed inside. When light is incident on the light diffusion powder, refraction and scattering occur, so that the light is diffused in different directions, making the brightness of the light source more uniform. The light guide member 41 has good light transmission.

[0052] The light guide 41 has a folded light path, which realizes a longer light transmission distance in a limited space. The ring-shaped light guide 41 combines the ring-shaped arrangement of multiple point light emitting elements 42, which can realize uniform light emission of the ring-shaped exit surface 411a. The point light emitting element 42 emits a point light source within a certain angle range and is incident on the incident surface 412a. The light rays are reflected by the first reflecting surface 412b and the second reflecting surface 411b, which can extend the light path distance in a small space. In combination with the light diffusion powder inside the light guide 41, the light rays are uniformly diffused, the light diffusion effect is increased, and the point light source of the point light emitting element 42 is converted into a surface light source emitted on the exit surface 411a. Adjacent two point light emitting elements 42 form partially overlapping exit light on the exit surface 411a, which reduces the dark area between the exit light formed by adjacent two point light emitting elements 42, and realizes uniform light emission of the ring-shaped extended exit surface 411a.

[0053] In some embodiments, referring to 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 circular truncated cone side surfaces or inclined surfaces (planes). This makes the light guide 41 easy to shape.

[0054] For example, the point light emitting element 42 is an LED lamp bead. The number of point light emitting elements 42 is 10, the point light emitting elements 42 are arranged on a circle or a rounded rectangle, and the point light emitting elements 42 adopt side light emission. The thickness of the light guide 41 in the second direction A2 is 6 mm. In combination with the light diffusion powder distributed in the light guide 41, the multiple point light emitting elements 42 can realize uniform light emission of the exit surface 411a of the light guide 41.

[0055] In some embodiments, referring to Figure 4 , Figure 8 , the axial distribution of the point light emitting element 42 and the light guide 41 of the exit surface 411a. This can make the overall structure of the light emission assembly 40 compact and occupy less space. This makes the light emission assembly 40 applicable in a space-compact scene, such as an electronic device with a small volume.

[0056] In some embodiments, referring to Figure 4 , Figure 8 , the surface of the ring-shaped part 411 forms the second reflecting surface 411b and the exit surface 411a, and each reflecting part 412 forms an incident surface 412a and a first reflecting surface 412b. In combination with Figure 8 , the point light emitted by the point light emitting element 42 enters the incident surface 412a of the corresponding reflecting part 412, and the light rays are refracted and scattered when passing through the light diffusion powder inside the light guide 41, realizing the diffusion of the light rays in different directions. The light rays are reflected by the first reflecting surface 412b of the reflecting part 412, then reflected by the second reflecting surface 411b of the ring-shaped part 411, and uniformly emitted on the exit surface 411a.

[0057] In some embodiments, referring 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 shape. This makes the light guide 41 easy to manufacture. 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, then reflected on the ring-shaped second reflecting surface 411b, and finally emitted from the exit surface 411a.

[0058] In some embodiments, referring to Figure 4 , Figure 8 , the exit surface 411a includes a first sub-exit surface 411a1 and a second sub-exit surface 411a2, the first sub-exit surface 411a1 and the second reflecting surface 411b are arranged to face each other along a first direction A1, and the second sub-exit surface 411a2 is connected between the second reflecting surface 411b and the first sub-exit surface 411a1. The light is emitted through the first sub-exit surface 411a1 and the second sub-exit surface 411a2, so that the light emitting assembly 40 has a better light emitting effect.

[0059] In some embodiments, referring to Figure 4 , Figure 8 , the thickness of the light guide 41 ranges from 5mm to 10mm. By arranging the light guide 41 to have a small thickness, the point light emitting element 42 can convert the point light source of the point light emitting element 42 into a surface light source output from the light guide 41 in combination with the light diffusion powder distributed in the light guide 41. The overall structure is very thin and can be applied in a compact space.
