[0042] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.
[0043] Referring to Figure 1 and Figure 2 , the present application provides an earphone charging box, which comprises an indicator light 21, a battery 1 and a light guide structure of the indicator light 21, and the indicator light 21 is used to indicate the power or charging state of the battery 1. For example, yellow is displayed when the battery power is sufficient, red is displayed when the power is low, and green is displayed when charging.
[0044] It can be understood that the light guide structure of the indicator light 21 of the embodiment can be applied to other electronic devices with indicator lights, such as mobile phones, tablets, computers, mainframes, displays, servers, and various terminals or devices, and the indicator light is not limited to indicating the power, for example, it can also be used to indicate the working state of the electronic device, such as a fault indicator light or a signal light.
[0045] The light guide structure of the indicator light 21 mainly includes a shell 10, a circuit board 20, and a light shielding piece 30. The shell 10 has a light outlet 110 arranged on the surface thereof. The light outlet 110 can be a through hole or a light-transmitting window. The circuit board 20 is arranged in the shell 10, and the indicator light 21 is arranged on the first surface (e.g., the lower surface in FIG. Figure 1 )
[0046] As shown in FIGS. Figure 1 , Figures 3-6 , the light shielding piece 30 is used to shield light and provide a light outlet channel. The light shielding piece 30 mainly includes a light shielding cover 31 and a limiting part. The light shielding cover 31 is arranged on the first surface (e.g., the lower surface in FIG. Figure 1 ) of the circuit board 20. The light shielding cover 31 has a receiving groove 310 and a light outlet channel 311. The receiving groove 310 is used to accommodate the indicator light 21. The light outlet channel 311 is connected to the receiving groove 310 and the light outlet 110. The outlet of the light outlet channel 311 is opposite to the light outlet 110 of the shell 10. The limiting part is connected to the light shielding cover 31 and extends to the second surface of the circuit board 20 opposite to the first surface, so as to constrain and limit the light shielding piece 30 on the circuit board 20.
[0047] Exemplarily, the limiting part includes a connecting arm 32 and a hanging ear 33. The connecting arm 32 is connected to the light shielding cover 31 and extends from the side wall of the light shielding cover 31 in a direction away from the receiving groove 310. The hanging ear 33 is bent from one end of the connecting arm 32 away from the receiving groove 310 and abuts against the second surface (e.g., the upper surface in FIG. Figure 1 ) of the circuit board 20. Through the cooperation between the hanging ear 33 and the light shielding cover 31, a clamping interval in which the circuit board 20 is clamped is formed.
[0048] After the light-shielding component 30 is installed on the circuit board 20, the receiving groove 310 is located below the circuit board 20, and the hanging ear 33 is located above the circuit board 20. The receiving groove 310 is attached to the lower surface of the circuit board 20, forming a receiving space to accommodate the indicator light 21. The hanging ear 33 is attached to the upper surface of the circuit board 20, so that the circuit board 20 is held between the upper surface of the receiving groove 310 and the lower surface of the hanging ear 33. In this way, the receiving groove 310 prevents light leakage around the indicator light 21, and the light emitted by the indicator light 21 can only be emitted from the light outlet 110 along the light emission channel 311. During assembly, simply assemble the light-shielding component 30 on the indicator light 21 on the circuit board 20, and then install the circuit board 20 into the housing 10, so that the outlet of the light emission channel 311 is aligned with and connected to the light outlet 110.
[0049] In some embodiments, the indicator light 21 may be located on the upper surface of the circuit board 20, the receiving groove 310 may be located above the circuit board 20, and the hanging ear 33 may be located below the circuit board 20.
[0050] Combination Figure 4 , Figure 5 and Figure 7 As shown, in one embodiment, a notch 22 is provided on the side of the circuit board 20 near the indicator light 21. The connecting arm 32 is at least partially embedded in the notch 22. Preferably, the connecting arm 32 can extend out of the notch 22, which can further improve the stability of the installation between the light shield 30 and the circuit board 20. Exemplarily, a notch 22 is provided on each of the two opposite sides of the indicator light 21, and a connecting arm 32 extends from each side of the light shield 31, with each connecting arm 32 correspondingly embedded in a notch 22. A hook 33 can extend from each connecting arm 32, and the hook 33 can be set perpendicular to the connecting arm 32. The figure shows the case where the hooks 33 on each connecting arm 32 extend away from each other, that is, the two hooks 33 extend away from the indicator light 21 between them.
[0051] During the installation of the light shield 30 onto the circuit board 20, two connecting arms 32 need to be inserted into the corresponding notch slots 22, the light shield 31 is used to cover the indicator light 21, and two hooks 33 are used to hook the upper surface of the circuit board 20. The two hooks 33 and the light shield 31 respectively limit the upper and lower surfaces of the circuit board 20. The two connecting arms 32 further restrict the movement of the light shield 30 relative to the circuit board 20 in the lateral direction. In this way, the light shield 30 can be firmly engaged with the circuit board 20.
[0052] To further improve the combination reliability of the circuit board 20 and the light shielding member 30, a resilient arch portion 320 is arranged on the surface of the connecting arm 32 facing away from the accommodating groove 310, and correspondingly, a recess portion 220 is arranged on the surface of the notch groove 22 facing away from the indicator lamp 21, the arch portion 320 is clamped in the recess portion 220, and the arch portion 320 is in interference fit with the recess portion 220, so that the connecting arm 32 is not easy to be pulled out after being clamped in the notch groove 22. Exemplarily, the outer surface of the arch portion 320 is arc-shaped, which can facilitate the connecting arm 32 to be smoothly clamped in or pulled out of the notch groove 22 when a proper external force is applied, thereby improving the convenience of mounting or dismounting the light shielding member 30.
[0053] It can be understood that in other embodiments, the number of the hanging ears 33 can also be not limited to two, for example, can be one or more than two. The light shielding member 30 is made of a light shielding material, and the light shielding member 30 can be integrally arranged or partially arranged and then assembled.
[0054] In one embodiment, as shown in Figure 4 , a certain distance is formed between each connecting arm 32 and the inner wall of the accommodating groove 310, that is, a stepped surface is formed between the connecting arm 32 and the top surface of the accommodating groove 310, and when the connecting arm 32 is clamped in the notch groove 22, the part of the circuit board 20 on which the indicator lamp 21 is arranged is overlapped and attached to the stepped surface, which can ensure the light shielding effect to a certain extent.
[0055] In one embodiment, the light shielding member 30 further comprises a connecting plate 34, the connecting plate 34 is connected between the two connecting arms 32, and the connecting plate 34 and the two connecting arms 32 form a U-shaped limiting portion 340 which is in communication with the accommodating groove 310, and the part of the circuit board 20 on which the indicator lamp 21 is arranged is inserted into the U-shaped limiting portion 340 and abuts against the U-shaped limiting portion 340. Through the cooperation between the connecting plate 34, the two connecting arms 32 and the light shielding cover 31, light leakage can be avoided at the joint between the circuit board 20 and the accommodating groove 310.
[0056] In one embodiment, the light outlet channel 311 is arranged on the side wall of the light shielding cover 31 facing away from the circuit board 20, and the surface of the light shielding member 30 on which the light outlet channel 311 is arranged abuts against the inner wall of the shell 10. The connecting plate 34 is connected to the light shielding cover 31, and on the side facing the light outlet 110 of the shell 10, the connecting plate 34 is smoothly connected to the light shielding cover 31 to form a complete joint surface. As shown in Figure 8 and Figure 9 , the joint surface can be an inclined surface, and the joint surface and the bottom surface of the light shielding cover 31 form an obtuse angle, and when the circuit board 20 is mounted in the shell 10, the joint surface of the light shielding member 30 is tightly attached to the inner wall of the shell 10, and the light shielding member 30 is pressed tightly against the inner wall of the shell 10 by the circuit board 20.
[0057] It can be understood that in other embodiments, the light exit channel 311 can also not be formed on the side wall of the light shield body 31 facing away from the circuit board 20, that is, the light exit channel 311 is not formed on the surface of the light shielding member 30 abutting the inner wall of the housing 10, for example, the light exit port 110 of the housing 10 is at the bottom, the surface of the light shielding member 30 abutting the housing 10 faces right, and the surface of the light shielding member 30 on which the light exit channel 311 is formed faces down.
[0058] In the present embodiment, it is shown that the two hanging ears 33 are arranged in line on two different sides of the accommodating groove 310. It can be understood that in other embodiments, the two hanging ears 33 can also face away from the joint surface, that is, extend towards the middle of the circuit board 20.
[0059] As shown in Figure 1 , Figure 8 and Figure 9 , the housing 10 specifically includes a top-open bottom shell 11 and a mounting bracket 12 fixed in the bottom shell 11. The inner wall of the bottom shell 11 includes a mounting surface inclined towards the top of the bottom shell 11 (i.e. obliquely upwards), and the light exit port 110 is formed on the mounting surface. The circuit board 20 is fixed to the lower end of the mounting bracket 12 by fixing members such as screws, and the upper part of the mounting bracket 12 is fixed to the opening at the top of the bottom shell 11 by buckling or screws. As shown in Figure 2 , the mounting bracket 12 includes a first fixing part 121 transversely, a second fixing part 122 longitudinally, and a charging compartment 120 arranged in the first fixing part 121 for accommodating the Bluetooth headset. The first fixing part 121 is mounted to the bottom shell 11 to close the opening of the bottom shell 11. The circuit board 20 is fixed to the second fixing part 122 by fixing members such as screws, and the circuit board 20 is transversely fixed to the lower end of the second fixing part 122. The battery 1 is mounted into the space enclosed by the first fixing part 121, the circuit board 20 and the second fixing part 122.
[0060] Exemplarily, the bottom of the battery 1 is at least partially supported on the light shielding member 30. In an embodiment, the surface (upper surface) of the hanging ear 33 facing away from the light shielding body 31 is provided with a supporting surface 330, which can be recessed to match the outer shape of the supported structure. In an embodiment, the supporting surface 330 can have a certain inclination angle towards the second fixing part 122, for example, the bottom surface of the battery 1 is arc-shaped, and the supporting surface 330 is arc-shaped to match the shape of the bottom surface of the battery 1. The supporting surface 330 and the second fixing part 122 respectively limit the battery 1 transversely in two different directions. It can be understood that by the battery 1 exerting pressure on the supporting surface 330, the friction between the hanging ear 33 and the circuit board 20 can be increased, thereby ensuring the reliability of the installation between the light shielding member 30 and the circuit board 20.
[0061] In the process of assembling the earphone charging box, first, the circuit board 20 is fixed at the end of the mounting frame 12, and the battery 1 is installed into the space between the mounting frame 12 and the circuit board 20, then the mounting frame 12 is assembled into the opening of the bottom shell 11 from top to bottom, when the light shielding piece 30 abuts against the mounting surface, the mounting frame 12 is fixed to the bottom shell 11. Under the extrusion of the mounting frame 12, the light shielding piece 30 is tightly abutted against the inclined mounting surface of the bottom shell 11.
[0062] As Figure 8 and Figure 9 In an embodiment, the inner wall of the bottom of the bottom shell 11 includes a step-shaped support portion 112 which is arranged adjacent to the mounting surface and at substantially the same height as the mounting surface in the bottom shell 11. A plurality of first support ribs 113 can be protruded along the circumference of the inner wall of the bottom of the bottom shell 11 at intervals, and the top surface of the first support ribs 113 is flush with the support portion 112. When the circuit board 20 is assembled into the bottom shell 11, the circuit board 20 can be lowered to be supported by the first support ribs 113 along with the mounting frame 12, and the four sides of the circuit board 20 are supported by the support portion 112. When the circuit board 20 is embedded in the support portion 112, the abutting surface of the light shielding piece 30 is directly opposite to the mounting surface. In addition, the inner wall of the bottom of the bottom shell 11 can also be provided with an inclined guide surface 114 which is arranged to be flared towards the circumference from bottom to top, and the guide surface 114 is adjacent to the support portion 112 below. During the process of assembling the circuit board 20, the guide surface 114 can guide the circuit board 20 to be installed into the support portion 112.
[0063] In an embodiment, the mounting surface of the bottom shell 11 forms a limiting groove 111 which is adjacent to and directly opposite to the light shielding piece 30, and the light outlet 110 is arranged in the limiting groove 111. The light shielding piece 30 is abutted in the limiting groove 111, and at least one of the abutting surfaces of the limiting groove 111 and the light shielding piece 30 towards each other is an inclined surface. The limiting groove 111 and the light shielding piece 30 can be installed in a face-to-face abutting manner.
[0064] It can be understood that a light shielding piece can also be arranged between the light shielding piece 30 and the inner wall of the bottom shell 11 to further ensure the light shielding performance between the light shielding piece 30 and the bottom shell 11. The outer shell 10 also includes an upper cover 13 which is rotatably covered on the opening of the bottom shell 11. By rotating the upper cover 13, the wireless earphone assembled in the mounting frame 12 can be covered therein, thereby facilitating carrying.
[0065] In order to support the light shielding piece 30 from the bottom, a plurality of second supporting ribs 115 can be further arranged on the inner wall of the bottom of the bottom shell 11, and the second supporting ribs 115 are arranged adjacent to the mounting surface and opposite to the lower part of the light shielding piece 30. When the circuit board 20 is installed in place, the second supporting ribs 115 are supported on the lower surface of the light shielding cover 31. In this way, the two sides of the light shielding piece 30 are respectively limited by the circuit board 20 and the inner part of the bottom shell 11, the lower part of the light shielding piece 30 is supported by the second supporting ribs 115, the circuit board 20 is clamped with the light shielding piece 30, and the light shielding piece 30 is firmly positioned on the circuit board 20.
[0066] In one embodiment, the bottom of the bottom shell 11 is provided with a charging hole 2, and the lower surface of the circuit board 20 is further provided with a charging interface 3. When the circuit board 20 is installed, the charging interface 3 faces the bottom of the bottom shell 11 and is at least partially inserted into the charging hole 2, so that the user can charge the battery 1 by inserting the charging connector into the charging hole 2.
[0067] It can be understood that in other embodiments, the charging interface 3 can also be arranged on different surfaces of the circuit board 20 respectively with the indicator light 21.
[0068] In summary, the present application uses the circuit board and the light shielding piece to cooperate with light guiding, and under the cooperation of the hanging ears, the connecting arms and the light shielding cover, the hanging ears of the light shielding piece and the light shielding cover are respectively positioned on different surfaces of the circuit board, so that the light shielding piece can be quickly and conveniently fixed to the indicator light of the circuit board, which can prevent light leakage and accurately guide the light emitted by the indicator light to pass through the shell without the need of glue bonding, thereby improving the production efficiency and reducing the process cost. In addition, the shape of the inner part of the bottom shell is optimized, which can reliably support the circuit board and the light shielding piece and guide the circuit board and the light shielding piece to be quickly installed and positioned.
[0069] The above is only a specific embodiment of the present application, and it should be noted that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
