[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0011] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0012] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0013] Currently, in order to enhance the user's sensory experience, some electronic devices often have light strips installed on their housings. Specifically, multiple clearance holes are set on the housing, and the light strip includes a PCB board and a light guide strip. The PCB board is located on the inside of the housing, and multiple LEDs on the PCB board extend into the clearance holes. The light guide strip is located on the outside of the housing and covers the LEDs. However, when the current light strip emits light, there is obvious light decay and shadow at the end of the light guide strip, which weakens the user's sensory experience.

[0014] The reason for this is that the clearance holes in the casing of current electronic devices are matched with the size of the LEDs on the PCB light board. The effective light-emitting area of ​​the LED is the cross-sectional area of ​​the clearance hole. When the LEDs in the middle position emit light, the light-emitting areas corresponding to them on the light guide strip can overlap, thus producing greater brightness. However, when the LEDs at the ends emit light, the light-emitting areas corresponding to them on the light guide strip do not have an overlapping effect, resulting in relatively lower brightness. This is the main reason why there is obvious light decay shadow at the ends of the light guide strip.

[0015] In view of this, the present invention provides a light-emitting structure and an electronic device, which can at least improve the problem of obvious light decay and shadow at the end of the light-emitting part when the light-emitting strip of the current electronic device is emitting light by increasing the light-emitting area of ​​the light-emitting part at the end.

[0016] To facilitate understanding of the light-emitting structure provided by this utility model, the following description is provided in conjunction with the accompanying drawings, wherein... Figure 1 A schematic diagram of one embodiment of the light-emitting structure (partial structure) provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the exploded structure of the light-emitting structure; Figure 3 for Figure 2 A schematic diagram of the structure of one of the shell segments of the middle shell; Figure 4 for Figure 3 A magnified structural diagram of part A in the middle; Figure 5 for Figure 3 Another structural schematic diagram of the segmented middle shell; Figure 6 for Figure 5 A magnified structural diagram of part B in the middle; Figure 7 for Figure 3 A schematic diagram of the assembly structure of the middle shell segments and the light-emitting circuit board; Figure 8 for Figure 7 A magnified structural diagram of part C in the middle; Figure 9 for Figure 7 A schematic diagram of the assembly structure of the middle shell segment and the light-emitting circuit board from another perspective; Figure 10 for Figure 9 A magnified schematic diagram of the local structure of D.

[0017] On the one hand, please refer to Figure 1 and Figure 2 In one embodiment of this utility model, the light-emitting structure 100 includes a housing 1, a light-emitting circuit board 2, and a light guide strip 3. The housing 1 is provided with a plurality of clearance holes 11 arranged at intervals along a first direction X. The plurality of clearance holes 11 include a first clearance hole 11a at the end. The first clearance hole 11a has a mounting section 111a and a clearance section 112a distributed along the first direction X. The light-emitting circuit board 2 is disposed on the inner side of the housing 1. The light-emitting circuit board 2 has a plurality of light-emitting parts 21. The plurality of light-emitting parts 21 are respectively inserted into the plurality of clearance holes 11. The plurality of light-emitting parts 21 include a first light-emitting part 21a. The first light-emitting part 21a is disposed in the mounting section 111a of the first clearance hole 11a. The light guide strip 3 is disposed on the outer side of the housing 1 and covers the plurality of light-emitting parts 21. The clearance section 112a of the first clearance hole 11a is configured to avoid the sidewall of the first light-emitting part 21a to increase the light-emitting area of ​​the first light-emitting part 21a.

[0018] Please see Figure 4 and Figure 8 The phrase “the first clearance hole 11a has an installation section 111a and a clearance section 112a distributed along the first direction X” can be understood as follows: the first clearance hole 11a is elongated along the first direction X to divide the installation section 111a and the clearance section 112a, wherein the clearance section 112a should be at least far away from the other clearance holes 11 in the first direction X.

[0019] The "light-emitting circuit board 2" has multiple light-emitting parts 21. This should be understood as multiple light-emitting parts 21 integrated on the light-emitting circuit board 2. The number of light-emitting parts 21 should be equivalent to the number of clearance holes 11, and the spacing between two adjacent light-emitting parts 21 should be equivalent to the spacing between two adjacent clearance holes 11, so that the multiple light-emitting parts 21 can accurately extend into the corresponding clearance holes 11. The light-emitting parts 21 typically have a certain thickness; therefore, the light-emitting parts 21 have sidewalls, and these sidewalls also have a certain light-emitting area. In the light-emitting parts 21 other than the first light-emitting part 21a, their sidewalls are blocked by the corresponding clearance holes 11, limiting their light-emitting area to the cross-sectional area of ​​the clearance hole 11. The first light-emitting part 21a is located in the mounting section 111a of the first clearance hole 11a, and its sidewall in the first direction X can be exposed outward through the clearance section 112a of the first clearance hole 11a. Figure 8 As shown, this increases the light-emitting area of ​​the first light-emitting part 21a.

[0020] The extension direction of the "light guide strip 3" is the same as the arrangement direction of the multiple light-emitting parts 21, that is, it extends along the first direction X. The function of the light guide strip 3 is to block the outside of the multiple light-emitting parts 21, thereby performing light mixing processing on the multiple light-emitting parts 21, so that the brightness of the light emitted through the light guide strip 3 is more uniform. This utility model embodiment does not limit this.

[0021] In the technical solution provided by this utility model, the first light-emitting part 21a is disposed in the mounting section 111a of the first clearance hole 11a. The clearance section 112a of the first clearance hole 11a can clearance the side wall of the first light-emitting part 21a in the first direction X, thereby increasing the light-emitting area of ​​the first clearance hole 11a and improving the brightness of the end position of the light guide strip 3 corresponding to the first light-emitting part 21a. This improves the problem of obvious light decay and shadow at the end of the light strip of the current electronic device when it emits light, and enhances the user's sensory experience.

[0022] Please see Figure 1 and Figure 2 In some embodiments, multiple clearance holes 11, light-emitting circuit boards 2, and light guide strips 3 are arranged in a one-to-one correspondence to form light-emitting groups, and multiple light-emitting groups are arranged along the first direction X.

[0023] "Multiple light-emitting groups are arranged along the first direction X" includes multiple light-emitting groups arranged at intervals along the first direction X and multiple light-emitting groups arranged end to end along the first direction X.

[0024] Compared to the solution of setting a single light-emitting circuit board 2 and light guide strip 3 within a unit long distance along the first direction X, the above technical solution arranges multiple light-emitting groups in the first direction X, which is equivalent to setting the light-emitting circuit board 2 and light guide strip 3 in segments, thereby significantly reducing the difficulty of production, transportation and installation of the light-emitting circuit board 2 and light guide strip 3.

[0025] Please see Figure 1 In some embodiments, in two adjacent light-emitting groups, the ends of the two light guide strips 3 are connected to each other.

[0026] Since the light guide strip 3 is positioned in a corresponding manner with the multiple light-emitting parts 21 and the multiple clearance holes 11, the phrase "the ends of the two light guide strips 3 are connected to each other" means that in two adjacent light-emitting groups, the multiple light-emitting parts 21 and the multiple clearance holes 11 can be arranged continuously and evenly. The phrase "connected to each other" can also be understood as splicing together, thus presenting an integrated light guide strip 3 in appearance.

[0027] In the above technical solution, the ends of the two light guide strips 3 are connected to each other, which can present a continuous light-emitting effect. Based on this, multiple light-emitting groups can be set on different surfaces of the housing 1, which can present a variety of complex shapes. It can also replace the setting of long-distance integral light-emitting circuit board 2 and light guide strip 3, reducing the setting difficulty. Due to the existence of the avoidance section 112a in the first clearance hole 11a, the first light-emitting part 21a has a larger light-emitting area, thereby compensating for the brightness at the end position of the light guide strip 3 and eliminating the problem of light decay shadow that easily occurs at the connection position of the segmented light guide strip 3.

[0028] Please see Figure 1 and Figure 2 In some embodiments, in two adjacent light-emitting groups, two light-emitting circuit boards 2 are connected in series via connecting wire harnesses 4.

[0029] Compared to the solution of individually powering and controlling multiple light-emitting circuit boards 2, the above technical solution connects two adjacent light-emitting circuit boards 2 in series through the connecting wire harness 4, so that multiple light-emitting circuit boards 2 can emit light synchronously and change colors, and the light emission synchronization rate of multiple light-emitting circuit boards 2 is higher.

[0030] In some embodiments, the first direction X is set as the circumferential direction of the housing 1; the housing 1 includes a plurality of housing segments 1a, which are interconnected along the circumferential direction, wherein a plurality of light-emitting groups are respectively disposed on the plurality of housing segments 1a.

[0031] For example, when the electronic device is a speaker, multiple light-emitting groups can be distributed on the four sides of the speaker; when the electronic device is smart glasses, please refer to [link / reference needed]. Figure 1The housing 1 of the smart glasses may include multiple housing segments 1a, which are distributed circumferentially along the housing 1 and connected to each other. The circumferential direction of the housing 1 corresponds to the circumferential direction of the user's head. The multiple housing segments 1a include at least a front housing 1 and two side housings 1. In some embodiments, a rear housing 1 is also included. The front housing 1 corresponds to the forehead region of the head, the rear housing 1 corresponds to the back of the head region, and the two side housings 1 correspond to the two sides of the head region. Multiple light-emitting groups are distributed at least in the front housing 1 and the two side housings 1 of the smart glasses.

[0032] In the above technical solution, multiple light-emitting groups are respectively disposed on multiple shell segments 1a, so that the peripheral surface of the shell 1 has a light-emitting effect.

[0033] Please see Figure 8 and Figure 10 In some embodiments, the light-emitting circuit board 2 has a first plate segment 2a at the end in the first direction X, and a first light-emitting part 21a is disposed on the first plate segment 2a; a support part 12 is also disposed on the inner side of the housing 1, and the support part 12 is disposed on the side of the first plate segment 2a away from the first light-emitting part 21a.

[0034] "First plate segment 2a" refers to the plate segment of the light-emitting circuit board 2 located at the end position in the first direction X. The first light-emitting part 21a is disposed in the first plate segment 2a. Since the first clearance hole 11a extends along the first direction X and has an additional clearance section 112a compared to other clearance holes 11, it is difficult to obtain an installation foundation for the position of the first plate segment 2a corresponding to the clearance section 112a. In the above technical solution, a support part 12 is provided on the side of the first plate segment 2a away from the first light-emitting part 21a, which can provide stable support and limit for the first plate segment 2a.

[0035] For details on the connection method between the support part 12 and the housing 1, please refer to [link / reference]. Figure 10 The support portion 12 is connected to the housing 1 from both sides of the first plate segment 2a, thereby forming a semi-circular structure that can provide support and limit the first plate segment 2a from multiple directions.

[0036] In other embodiments, the first direction X is defined as the length direction of the light-emitting circuit board 2, and the first board segment 2a can also be mounted to the inside of the housing 1 at both ends in its width direction.

[0037] Please see Figure 1 and Figure 3 In some embodiments, the outer side of the housing 1 is provided with a mounting groove 13 extending along the first direction X, and a plurality of clearance holes 11 are provided on the bottom wall of the mounting groove 13; the light guide strip 3 is provided in the mounting groove 13.

[0038] In the above technical solution, a mounting groove 13 is provided on the outside of the housing 1, and the light guide strip 3 is installed in the mounting groove 13. This helps to maintain the smoothness of the outer surface of the housing 1 and eliminate the abruptness caused by the setting of the light guide strip 3. At the same time, the mounting groove 13 also has the function of controlling the light output direction, so that the light beam is uniformly emitted from the light guide strip 3 away from the outer surface of the housing 1, thereby enhancing the light emission intensity.

[0039] Please see Figure 4 and Figure 6 In some embodiments, the housing 1 has a connecting rib 14 located between two adjacent clearance holes 11; the light-emitting circuit board 2 is detachably connected to the connecting rib 14.

[0040] There are several ways in which the light-emitting circuit board 2 can be detachably connected to the connecting rib 14. For example, the light-emitting circuit board 2 can be connected to the connecting rib 14 by screws or by clips. The light-emitting circuit board 2 can be connected to all the connecting ribs 14 or only to some of them. For example, a connection position can be set every other connecting rib 14.

[0041] In the above technical solution, the light-emitting circuit board 2 makes full use of the connecting ribs 14 between two adjacent clearance holes 11 as mounting points, so that the light-emitting circuit board 2 can be evenly distributed with multiple connecting positions in the first direction X, which is beneficial to improving the installation stability of the light-emitting circuit board 2.
