[0038] In the description of the present invention, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0039] The present invention provides a light guide column installation structure. Figures 1 to 4 The light guide column installation structure includes a light guide column 201, a box body 101, a clamping body 105, an upper shell 103 and a lower shell 104.

[0040] Reference Figure 1 and Figure 2 The box body 101 is hollow, the inner cavity of the box body 101 is the installation cavity 102, the light guide column 201, the card body 105, the upper shell 103 and the lower shell 104 are all arranged in the installation cavity 102, and the two card bodies 105 are both protruding from the wall of the installation cavity 102.

[0041] Reference Figure 2 and Figure 3 The lower shell 104 includes a main body 206 and two upper positioning bodies 202, wherein the main body 206 has a receiving cavity 305 inside, and a part of the light guide column 201 is received in the receiving cavity 305. The two upper positioning bodies 202 are connected to both sides of the main body 206 and protrude relative to the side of the main body 206. The two clamping bodies 105 are also distributed on both sides of the main body 206, and the top of each clamping body 105 is respectively against the bottom of one upper positioning body 202. That is, under the gravity of the lower shell 104 itself, the clamping body 105 is against the upper positioning body 202, thereby supporting the lower shell 104.

[0042] Combination Figures 1 to 4 The upper shell 103 has a snap-fit ​​hole 301, the snap-fit ​​body 105 is inserted into the snap-fit ​​hole 301, and the hole wall of the snap-fit ​​hole 301 abuts against the snap-fit ​​body 105. The upper shell 103 covers the top of the lower shell 104, and at the same time, the upper shell 103 abuts against the main body 206, thereby preventing the lower shell 104 from moving along the protruding direction of the snap-fit ​​body 105 (referring to the protruding direction of the lower shell 104 relative to the wall surface of the installation cavity 102).

[0043] The assembly method of the light guide column installation structure is as follows: put the light guide column 201 into the lower shell 104; then put the lower shell 104 on the clamping body 105, so that the clamping body 105 abuts against the upper positioning body 202, and the main body 206 is located between the two upper positioning bodies 202; then clamp the upper shell 103 and the clamping body 105 (so that the clamping body 105 is clamped into the clamping hole 301), so that the upper shell 103 covers the top of the lower shell 104. Figure 1 and Figure 2 When the upper shell 103 is fixedly connected with the clamping body 105, the upper shell 103 covering the top of the lower shell 104 can prevent the lower shell 104 from moving upward and backward; the clamping body 105 and the upper positioning body 202 can prevent the lower shell 104 from moving downward. If the main body 206 moves to the left or right, the main body 206 will also be blocked by the clamping body 105; and the wall surface of the installation cavity 102 can prevent the lower shell 104 from moving forward. Therefore, when the upper shell 103 is installed, the movement of the lower shell 104 in all directions is restricted, the lower shell 104 is fixed to the wall surface of the installation cavity 102, and the light guide column 201 installed inside the lower shell 104 is also fixed to the wall surface of the installation cavity 102.

[0044] The light guide column installation structure provided by the present invention requires only simple placement, snap-on and other operations during the assembly process, without the need for dispensing or applying glue, and without the need to wait for the glue to cure after the assembly is completed. The light guide column installation structure provided by the present invention is easy to assemble, and is beneficial to improving the installation efficiency of the light guide column 201 and the assembly efficiency of the headphone charging box 501.

[0045] Reference Figure 4 and Figure 5, the box body 101 also has a light-transmitting hole 401 connected to the mounting cavity 102. The light guide column 201 itself is made of materials such as glass and transparent plastic. The light entering the light guide column 201 will be reflected and refracted inside the light guide column 201, and will eventually be emitted to the outside of the box body 101 through the light-transmitting hole 401. In some embodiments, both the upper shell 103 and the lower shell 104 can be made of light-shielding materials. For example, both the lower shell 104 and the upper shell 103 are made of black and opaque plastic. This arrangement can reduce the loss of light, prevent light from being emitted from the wrong position (for example, directly through the box body 101), and ensure that enough light is emitted from the light-transmitting hole 401. At the same time, by directly setting the lower shell 104 and the upper shell 103 as light-shielding components, the step of attaching light-shielding cotton around the light guide column 201 can be omitted, thereby improving the assembly convenience of the headphone charging box 501.

[0046] Reference Figure 4 The main body 206 also has a light inlet 402 for light to pass through, the light inlet 402 is connected to the accommodating cavity 305, and the light inlet 402 faces the LED light-emitting chip on the main board 602. The LED light-emitting chip (i.e. Figure 7 The light emitted by the light source 701 can be injected into the accommodating cavity 305 through the light inlet 402, and then injected into the light guide column 201.

[0047] In order to allow light to be emitted from the light-transmitting hole 401, in some embodiments, a portion of the light-guiding column 201 may be directly embedded in the light-transmitting hole 401. Figure 3 and Figure 4 The light guide column 201 includes a longitudinal portion 303 and a transverse portion 302. A portion of the longitudinal portion 303 is accommodated in the accommodation cavity 305, and another portion of the longitudinal portion 303 is disposed outside the accommodation cavity 305. The portion of the longitudinal portion 303 outside the main body 206 is covered and shielded by the upper shell 103. The transverse portion 302 is connected to one side of the longitudinal portion 303 and protrudes relative to the side of the longitudinal portion 303. The transverse portion 302 is also located outside the accommodation cavity 305, and one end of the transverse portion 302 away from the longitudinal portion 303 is embedded in the light-transmitting hole 401.

[0048] When the light guide column 201 is provided with the transverse portion 302, the cooperation between the transverse portion 302 and the light-transmitting hole 401 can also realize the positioning between the light guide column 201 and the box body 101, further improving the installation convenience of the light guide column 201. Figure 2 and Figure 4 When the transverse portion 302 is provided, the light guide column 201 can be first inserted into the lower shell 104, and then the user holds the lower shell 104 and the light guide column 201, and inserts the transverse portion 302 of the light guide column 201 into the light-transmitting hole 401 (at the same time, the upper positioning body 202 also gradually moves to the top of the clamping body 105).

[0049] In the case where the transverse portion 302 is provided, the hole wall of the light-transmitting hole 401 will abut against the transverse portion 302 to prevent the light guide column 201 from loosening and falling. In addition, when the light inlet 402 is provided at the bottom of the main body 206, it can be considered to set the area of ​​the light inlet 402 to be smaller than the minimum cross-sectional area of ​​the light guide column 201 to prevent the light guide column 201 from falling.

[0050] Reference Figure 2 In some embodiments, the lower shell 104 further includes two lower positioning bodies 203. The lower shell 104 is provided with an upper positioning body 202 and a lower positioning body 203 at the same time, which is conducive to improving the convenience of assembly between the lower shell 104 and the box body 101. The two lower positioning bodies 203 are respectively connected to the two sides of the main body 206, and the lower positioning bodies 203 are protruding relative to the outer surface of the main body 206. The upper positioning body 202 and the lower positioning body 203 located on the same side of the main body 206 are arranged at intervals, thereby forming a first positioning groove 304, and the clamping body 105 is accommodated in the first positioning groove 304. The first positioning groove 304 defined by the upper positioning body 202 and the lower positioning body 203 has a positioning function for the clamping body 105, which facilitates the assembly between the box body 101 and the lower shell 104.

[0051] Reference Figure 2 In some embodiments, the engaging body 105 includes a first protruding portion 204 and a second protruding portion 205, one end of the first protruding portion 204 is connected to the wall of the mounting cavity 102, the second protruding portion 205 is connected to the side of the first protruding portion 204, and the second protruding portion 205 protrudes in a direction away from the light guide column 201 relative to the first protruding portion 204. The first protruding portion 204 is used to support the upper positioning body 202; in the case where the lower positioning body 203 is provided, the first protruding portion 204 is provided in the first positioning groove 304. The second protruding portion 205 protruding laterally is used to engage with the upper shell 103.

[0052] The present invention also provides an earphone charging box 501, which includes the light guide column installation structure in the above embodiment. The light guide column 201 of the earphone charging box 501 is easy to install, and the overall assembly of the earphone charging box 501 is easy.

[0053] Specifically, refer to Figures 5 to 8In some embodiments, the earphone charging box 501 may include a box body 101, an upper cover 502, a middle cover 801, a main board 602 and a battery 803. The battery 803 and the main board 602 are both arranged in the installation cavity 102, and the upper cover 502 is rotatably connected to the box body 101. The battery 803 and the main board 602 are electrically connected through a wire. The main board 602 has a first connector 603 and a second connector 604, the first connector 603 can be set as a pogo pin, and the second connector 604 can be set as a type-c interface; of course, the form of the first connector 603 and the second connector 604 is not limited to the form mentioned above, and can be specifically adjusted to other connectors that can be used to achieve electrical connection. The earphone charging box 501 also includes a middle cover 801, which is connected to the box body 101, and the middle cover 801 has two earphone cavities 802 for accommodating earphones, and the first connector 603 passes through the middle cover 801 and penetrates into the earphone cavity 802. The first connector 603 is used to contact the earphone so that the battery 803 charges the earphone, and the second connector 604 is used to connect with an external cable so that the external power source charges the battery 803. The circuit structure of the mainboard 602 for realizing the above charging function belongs to the well-known technology in the art and will not be described in detail here.

[0054] Reference Figure 7 The main board 602 also has a light source 701 (the light source 701 can be set as an LED light emitting chip). Figure 6 and Figure 7 The light source 701 is located near the edge of the main board 602, the light inlet 402 faces the light source 701, and a light shielding foam 605 is also arranged on the periphery of the light source 701. The light from the light source 701 enters the light guide column 201 through the light inlet 402, and then passes through the light guide column 201 and is emitted from the light transmission hole 401.

[0055] Reference Figure 6 In some embodiments, the earphone charging box 501 further includes an FPC 601, one end of which is electrically connected to the mainboard 602, and some electronic components such as sensors and switches may be provided on the FPC 601 to achieve some specific functions. For example, the FPC 601 may be provided with a Hall switch, and a magnet may be installed at the movable end of the upper cover 502. When the earphone charging box 501 is closed, the magnet installed on the upper cover 502 may trigger the Hall switch, and the mainboard 602 may determine that the earphone charging box 501 is closed according to the signal of the Hall switch, and accordingly turn off the indicator light.

[0056] Reference Figures 9 to 11In order to conveniently fix the end of the FPC 601 away from the mainboard 602, in some embodiments, the upper shell 103 has a mounting groove 901, and the end of the FPC 601 away from the mainboard 602 is arranged in the mounting groove 901, and the groove wall of the mounting groove 901 clamps the FPC 601 along the thickness direction of the FPC 601, thereby fixing the FPC 601. When fixing the end of the FPC 601 away from the mainboard 602, the assembler only needs to hold the FPC 601 and insert the FPC 601 into the mounting groove 901, and the fixing method of the FPC 601 is more convenient.

[0057] Reference Fig.10 In order to improve the convenience of inserting the FPC 601 into the mounting groove 901, a reinforcing plate 1002 may be provided in the FPC 601 to increase the strength and thickness of the end of the FPC 601 inserted into the mounting groove 901. Specifically, referring to the figure, the FPC 601 includes a substrate 1001 and a reinforcing plate 1002. The substrate 1001 is flexible, and a circuit may be printed on the surface of the substrate 1001. The reinforcing plate 1002 is attached to the surface of the substrate 1001, and the reinforcing plate 1002 is provided at one end of the substrate 1001 accommodated in the mounting groove 901. The reinforcing plate 1002 is also accommodated in the mounting groove 901 and is supported by the wall of the mounting groove 901; if the reinforcing plate 1002 is not provided, the wall of the mounting groove 901 directly contacts and clamps the substrate 1001.

[0058] The reinforcing plate 1002 can be set as a steel sheet, and the material of the reinforcing plate 1002 can also be selected from common reinforcing materials such as PI (polyimide) and FR-4 (FR-4 grade glass fiber epoxy resin). The shape of the reinforcing plate 1002 needs to be reasonably set to avoid the circuits and electronic components on the substrate 1001. In addition, the reinforcing plate 1002 can be attached to one side of the substrate 1001, or the reinforcing plate 1002 can be attached to both sides of the substrate 1001.

[0059] Compared with the FPC 601 without the reinforcement plate 1002, the end of the FPC 601 with the reinforcement plate 1002 has a greater thickness and hardness, and the end of the FPC 601 is less likely to collapse when the assembler holds the FPC 601, and the operation of inserting the FPC 601 with the reinforcement plate 1002 into the installation groove 901 is more convenient. In addition, the thickness of the end of the FPC 601 set in the installation groove 901 is relatively large, and accordingly, the height of the installation groove 901 can also be set relatively large, so as to avoid the height of the installation groove 901 being too small, which will lead to high difficulty in processing the upper shell 103 and difficulty in inserting the FPC 601 into the installation groove 901.

[0060] It should be noted that, since the FPC 601 can be bent or folded, the thickness direction of the FPC 601 mentioned in the present invention is based on the thickness direction of the substrate 1001 in the section where the FPC 601 is located in the mounting groove 901 .

[0061] In order to improve the assembly convenience of the FPC 601 , a guide positioning body 903 may be provided in the FPC 601 , and a second positioning groove 902 may be provided in the upper shell 103 .

[0062] Reference Fig. 9 and Fig.11 The upper shell 103 has a second positioning groove 902, and the bottom of the second positioning groove 902 is connected to the top of the installation groove 901. Fig.10 , FPC601 includes a substrate 1001 and a guide positioning body 903. The substrate 1001 is flexible. The guide positioning body 903 can be directly connected to the substrate 1001 and protrude relative to the surface of the substrate 1001. The guide positioning body 903 is accommodated in the second positioning groove 902, and the substrate 1001 is located in the installation groove 901. The wall surface of the second positioning groove 902 can abut against the guide positioning body 903, thereby achieving the positioning between the upper shell 103 and the FPC601. Fig. 9 For example, the wall surface of the second positioning groove 902 can constrain the movement of the guide positioning body 903 along the front-rear direction.

[0063] Reference Fig. 9 and Fig.10 In the case where the guide positioning body 903 and the second positioning groove 902 are provided, when the substrate 1001 slides into the installation groove 901 (or the substrate 1001 and the reinforcing plate 1002 slide into the installation groove 901 together), the guide positioning body 903 slides into the second positioning groove 902. Therefore, the positioning cooperation between the second positioning groove 902 and the guide positioning body 903 can not only ensure the position stability of the FPC 601 after the FPC 601 is installed, but also guide the movement of the FPC 601 during the movement of the FPC 601, so as to facilitate the installation of the FPC 601.

[0064] The guide positioning body 903 can be adjusted appropriately. Fig.10 The guide positioning body 903 is set to a cube shape, and the guide positioning body 903 can also be set to other polygonal shapes, or it can be set to a cylindrical shape, a spherical shape, etc. In addition, the guide positioning body 903 mainly functions for positioning and guiding, and does not need to be connected to the circuit on the FPC601. If the FPC601 includes a substrate 1001, a reinforcement plate 1002 and a guide positioning body 903, then the guide positioning body 903 can also be directly connected to the side surface of the reinforcement plate 1002 facing away from the substrate 1001, and protrude relative to the reinforcement plate 1002 and the substrate 1001.
