Description

Technical Field

[0001] The utility model relates to the field of LED displays, and particularly relates to an LED display device and an electronic product. Background Art

[0002] Some existing electronic products have an LED display function.

[0003] Among them, some electronic products are provided with a light-transmitting display window on an opaque housing, and an LED display module such as a digital tube is arranged on the inner side of the housing. Users observe the display pattern on the LED display module through the display window from the outside of the electronic product. However, since the display pattern is formed on the LED display module inside the housing, the viewing effect of the display pattern varies greatly from different viewing angles (when the user observes the display window directly, a better display pattern can be observed. When the user observes the display window at a certain inclination angle, the display pattern may be partially blocked), resulting in a poor user experience.

[0004] Some other electronic products are provided with a light guide channel on an opaque housing, an LED light source facing the light guide channel is arranged on the inner side of the housing, and a light diffusing film covering the light guide channel is attached to the outer surface of the housing. The light emitted by the LED light source is transmitted through the light guide channel to the light diffusing film, and the light diffusing film disperses and transmits the light, so as to form a display pattern with a relatively uniform lighting brightness on the light diffusing film. In this way, the viewing effect of the display pattern varies less from different viewing angles, which is beneficial to improving the user experience.

[0005] However, the light emitted by the LED light source will be dispersed in all directions under the action of the light diffusing film, which causes the light to be easily dispersed beyond the boundary / outline of the display pattern. On the one hand, this will cause light loss and reduce the brightness of the display pattern. On the other hand, it also causes the outline of the display pattern to be blurred, resulting in a poor display effect; moreover, the stronger the degree of light dispersion of the light diffusing film, the more uniform the brightness of each part of the display pattern, and the greater the light loss dispersed beyond the boundary of the display pattern, and the more blurred the boundary of the display pattern. Summary of the Utility Model

[0006] One of the purposes of the utility model is to overcome the above-mentioned defects of the prior art and provide an LED display device.

[0007] An LED display device for electronic products provided by the present utility model comprises an LED display function module and a housing assembly. The LED display function module is fixedly arranged inside the housing assembly, and the outer surface of the housing assembly constitutes the outer surface of the electronic product. The LED display function module includes a circuit board, an LED light source, and a board-side light-shielding structure. The housing assembly includes a housing-side light-shielding structure. The circuit board, the board-side light-shielding structure, and the housing-side light-shielding structure are sequentially distributed from inside to outside along the thickness direction of the housing assembly. The circuit board has a first main surface. The board-side light-shielding structure is fixedly arranged on the first main surface and has a first light-transmitting hole penetrating along the thickness direction. The LED light source is fixedly arranged on the first main surface and is located in the first light-transmitting hole. A first light-transmitting material is filled in the first light-transmitting hole and is formed by injecting and curing in a fluid state. The first light-transmitting material is located in a cavity of the first light-transmitting hole along the thickness direction close to the circuit board and submerges the LED light source. One end orifice of the first light-transmitting hole along the thickness direction away from the circuit board is a first orifice, and the first orifice is exposed outside the first light-transmitting material. The housing-side light-shielding structure has a second light-transmitting hole penetrating along the thickness direction. A second light-transmitting material is filled in the second light-transmitting hole and is formed by injecting and curing in a fluid state. The second light-transmitting material is located in a cavity of the second light-transmitting hole along the thickness direction away from the circuit board. One end orifice of the second light-transmitting hole along the thickness direction close to the circuit board is a second orifice, and the second orifice is exposed outside the second light-transmitting material. The first orifice and the second orifice are butt-connected and communicated along the thickness direction.

[0008] As can be seen from the above, the setting of the second light-transmitting material enables the present utility model to form a lit display pattern that can be observed from the outside on the housing assembly when the LED light source is turned on. In this way, the visual effect difference of the display pattern observed by the user from different perspectives is relatively small, which is beneficial to improving the user experience.

[0009] Moreover, the setting of the first light-transmitting material enables the present utility model to use an LED chip as the LED light source (the first light-transmitting material can be used to provide protection for the LED chip at the same time). Using an LED chip as the LED light source is beneficial to reducing the cost of the LED display device on the one hand, and is also beneficial to improving the performance consistency of each LED light source in the same LED display device / electronic product on the other hand.

[0010] In addition, the present utility model can reduce the loss of light during the propagation process by selecting a light-transmitting material with a relatively high light transmittance or good light guiding performance, which is beneficial to improving the lighting brightness of the display pattern of the LED display device.

[0011] In addition, since the propagation of light in the first light-transmitting material is restricted by the first light-transmitting holes, and the propagation of light in the second light-transmitting material is restricted by the second light-transmitting holes, the present utility model can, by selecting appropriate light-transmitting materials, disperse the light sufficiently, so that the brightness of the display pattern is uniform everywhere, and it is not easy to cause the boundary of the lit display pattern observed by the user from the outside of the LED display device to be blurred, which is beneficial to making the boundary of the lit display pattern clear.

[0012] The present utility model is beneficial to forming a lit display pattern with high brightness, uniform brightness and darkness, and clear boundary on the outer shell assembly, which is convenient for observation from the outside.

[0013] The first orifice of the present utility model is located outside the first light-transmitting material, and the second orifice is located outside the second light-transmitting material. This makes the cooperation between the first orifice and the second orifice not affected by the first light-transmitting material and the second light-transmitting material, and the cooperation between the outer shell assembly and the LED display function module not affected by the first light-transmitting material and the second light-transmitting material. Therefore, the present utility model can complete the production of the outer shell assembly and the LED display function module respectively in advance, and then, in the use scenario of the LED display device, only need to perform the mating installation of the outer shell assembly and the LED display function module (instead of assembling each part one by one), and an LED display device can be obtained, which is beneficial to improving the production efficiency of the LED display device in the use scenario and expanding the applicable range of the LED display device.

[0014] A preferred solution is that one end of the board-side light-shielding structure away from the circuit board in the thickness direction has a first light-shielding wall extending around the first orifice; one end of the shell-side light-shielding structure close to the circuit board in the thickness direction has a second light-shielding wall extending around the second orifice, and the second light-shielding wall is inserted into the outer periphery of the first light-shielding wall in the thickness direction, and / or the second light-shielding wall is inserted into the inner periphery of the first light-shielding wall in the thickness direction.

[0015] As can be seen from the above, through the insertion and cooperation of the first light-shielding wall and the second light-shielding wall, it is beneficial to reduce the leakage of light between the board-side light-shielding structure and the shell-side light-shielding structure, and it is beneficial to flexibly adjust the relative cooperation position between the LED display function module and the outer shell assembly by adjusting the insertion depth of the first light-shielding wall and the second light-shielding wall, which is beneficial to improving the adaptability of the cooperation between the LED display function module and the outer shell assembly and reducing the difficulty of the mating installation between the LED display function module and the outer shell assembly.

[0016] A further solution is that the number of the first light-transmitting holes is at least two, the number of the second light-transmitting holes is at least two, each first light-transmitting hole corresponds to each second light-transmitting hole one by one, and the first light-transmitting hole and the corresponding second light-transmitting hole are butt-connected and communicated in the thickness direction to form a light guide channel; the corresponding cooperation of the first light-shielding wall and the second light-shielding wall is blocked between adjacent light guide channels.

[0017] As can be seen from the above, this is beneficial to reducing the light crosstalk between different light guide channels.

[0018] A further solution is that the number of LED light sources is at least two, and each light guide channel corresponds to an LED light source.

[0019] A further solution is that the path along which the first light-shielding wall extends around the first orifice is a closed path, and the path along which the second light-shielding wall extends around the second orifice is a closed path.

[0020] Another preferred solution is that the outer surface of the housing-side light-shielding structure constitutes the outer surface of the electronic product.

[0021] Yet another preferred solution is that the housing assembly further includes a light-transmissive display surface shell layer, which is attached to the outer surface of the housing-side light-shielding structure and covers the orifice of the second light-transmitting hole on the outer surface of the housing-side light-shielding structure, and the outer surface of the display surface shell layer constitutes the outer surface of the electronic product.

[0022] A further solution is that the display surface shell layer is attached to the outer surface of the housing-side light-shielding structure by in-mold insert injection molding.

[0023] As can be seen from the above, the in-mold insert injection molding method, on the one hand, is beneficial to making the display surface shell layer closely fit the outer surface of the housing-side light-shielding structure, which is beneficial to using the display surface shell layer to block the orifice of the second light-transmitting hole on the outer surface of the housing-side light-shielding structure, thus facilitating the perfusion operation of the second light-transmitting material; on the other hand, it is easy to form a semi-transparent display surface shell layer by the in-mold insert injection molding method. Therefore, not only can a lit display pattern be formed on the display surface shell layer when the LED light source is turned on inside the housing assembly, but also when the LED light source is not turned on inside the housing assembly, the inner structure can be blocked and hidden by the display surface shell layer, making it difficult for users to observe the inner structure through the display surface shell layer, which is beneficial to making the appearance structure of the LED display device simple, and further beneficial to making the appearance structure of the corresponding electronic product simple. Moreover, the semi-transparent display surface shell layer formed in this way is not easily faded due to long-term friction and other usage operations during use; on the third hand, it is convenient to form a relatively thin display surface shell layer, which is further beneficial to reducing the stray propagation of light in the display surface shell layer, beneficial to ensuring a high clarity of the boundary of the display pattern, and beneficial to improving the display effect of the LED display device.

[0024] A further solution is that the thickness of the display surface shell layer is 0.1 to 0.2 millimeters.

[0025] A further solution is that the display surface shell layer is made of a semi-transparent material.

[0026] A further solution is that the thickness of the display surface shell layer is less than or equal to 1 millimeter;

[0027] In a further embodiment, the potting thickness dimension of the second light-transmitting material in the second light-transmitting hole is greater than or equal to 2 mm; the potting thickness dimension of the second light-transmitting material in the second light-transmitting hole is less than or equal to 8 mm.

[0028] In a further embodiment, the outer surface of the second light-transmitting material filled in the second light-transmitting hole is in contact with the inner surface of the display housing layer.

[0029] In a further embodiment, the display housing layer forms at least a part of the outer housing of the electronic product; alternatively, the side housing light-shielding structure includes a light-shielding housing, and the light-shielding housing forms at least a part of the outer housing of the electronic product.

[0030] In a further embodiment, the inner surface of the display housing layer is in contact with the outer surface of the side housing light-shielding structure.

[0031] In a further embodiment, the display housing layer seals the orifice of the second light-transmitting hole on the outer surface of the side housing light-shielding structure.

[0032] In yet another preferred embodiment, the cooperation between the LED display function module and the outer housing assembly has a positioning structure, and the positioning structure is used to position the cooperation position of the LED display function module and the outer housing assembly in a direction perpendicular to the thickness direction.

[0033] In a further embodiment, the positioning structure includes a positioning convex portion and a positioning concave portion. One of the positioning convex portion and the positioning concave portion is located on the LED display function module, and the other is located on the outer housing assembly. The positioning convex portion is inserted into the positioning concave portion along the thickness direction.

[0034] In yet another preferred embodiment, the LED light source is an LED lamp bead; alternatively, the LED light source is an LED chip, and the LED chip is electrically connected to a metal electrode on the circuit board.

[0035] In yet another preferred embodiment, a light diffusing agent for dispersing the propagation of light is mixed in the second light-transmitting material.

[0036] In yet another preferred embodiment, the light transmittance of the first light-transmitting material is greater than the light transmittance of the second light-transmitting material.

[0037] As can be seen from the above, it is thus convenient to select the first light-transmitting material with a relatively high light transmittance mainly considering reducing the light loss, and to select the second light-transmitting material mainly considering making the light propagate dispersedly sufficiently. This is conducive to making the light propagate more concentratedly to the outer housing assembly and forming a uniformly lit display pattern that can be observed from the outside on the outer housing assembly.

[0038] In yet another preferred embodiment, the second light-transmitting material formed by curing constitutes a light guide column.

[0039] As can be seen from the above, with the guiding effect of the light guide column, most of the light propagates from one end of the light guide column to the other end along the thickness direction, and a lit display pattern is formed on the housing assembly through the light guide column, which is beneficial to reducing light loss and improving the brightness of the display pattern.

[0040] A further solution is that a light diffusing agent for dispersing light propagation is mixed in the first light-transmitting material.

[0041] As can be seen from the above, this is beneficial to uniformly dispersing the light entering the light guide column, and further beneficial to uniformly dispersing the light exiting the light guide column.

[0042] Another preferred solution is that the board-side light-shielding structure includes a first light-shielding frame. The first light-transmitting hole penetrates the first light-shielding frame along the thickness direction, and the first hole opening is located on the first light-shielding frame. The LED display function module further includes a first potting fence, which is fixedly arranged on the circuit board and encloses a first potting groove area with the first main surface. The first light-shielding frame is inserted into the first potting groove area along the thickness direction when the first light-transmitting material is injected into the first potting groove area in a fluid state and has not yet solidified, and a partial hole section of the first light-transmitting hole located on the first light-shielding frame and far from the first hole opening is immersed in the first light-transmitting material; and / or, the shell-side light-shielding structure includes a second light-shielding frame. The second light-transmitting hole penetrates the second light-shielding frame along the thickness direction, and a second potting groove area is formed on the inner surface of the housing of the electronic product. The second light-shielding frame is inserted into the second potting groove area along the thickness direction after the second light-transmitting material is injected into the second potting groove area and has not yet solidified, and a partial hole section of the second light-transmitting hole located on the second light-shielding frame and far from the second hole opening is immersed in the second light-transmitting material.

[0043] A further solution is that the board-side light-shielding structure further includes a light-shielding base. The first light-transmitting hole penetrates the light-shielding base along the thickness direction, and the light-shielding base is integrally formed on the first potting fence. The first main surface, the light-shielding base and the first light-shielding frame are butt-jointed in sequence along the thickness direction and jointly enclose the first potting groove area.

[0044] A further solution is that the structure enclosing the second potting groove area is an integral structure.

[0045] The second object of the present invention is to overcome the above-mentioned defects of the prior art and provide an electronic product.

[0046] The electronic product provided by the present invention includes the aforementioned LED display device; the circuit board is the main control board of the electronic product; or the circuit board is a board electrically connected to the main control board of the electronic product.

[0057] In this embodiment, Figures 1 to 10 a unified three-dimensional rectangular coordinate system (right-handed system) is adopted to identify the relative orientation relationship between each component. Among them, the Z-axis direction is the first direction.

[0058] Please refer to Figures 1 to 10 , the electronic product in this embodiment is the control host of a massager. The control host of the massager includes the LED display device in this embodiment. The LED display device in this embodiment includes a housing assembly 100 and an LED display function module 200.

[0059] Optionally, in other embodiments of the present utility model, the electronic product may also be an intelligent skipping rope with an LED display function, an electric toothbrush, an intelligent speaker, an electronic clock, etc.

[0060] Regarding the housing assembly 100

[0061] Please refer to Figures 1 to 7 , in the housing assembly 100 of this embodiment, when a light source (the LED light source 9 described later) is turned on inside it, a display pattern such as a lit "88" character that can be observed from the outside is formed. The outer surface of the housing assembly 100 constitutes the outer surface of the electronic product. The inner and outer sides described in this embodiment are referenced based on the inner and outer sides of the housing assembly.

[0062] The housing assembly 100 includes a light-shielding housing 1, a display front shell layer 2, a second potting fence 3, a second light-shielding frame 4, and a second light-transmitting material 5. The light-shielding housing 1 constitutes the front shell of the electronic product (belonging to the outer shell) and encloses an installation cavity V100 with the rear shell 300 of the electronic product. The LED display function module 200 is fixedly installed in the installation cavity V100. The illustrated Z-axis direction is the thickness direction of the housing assembly 100. The negative Z-axis side of the housing assembly 100 is the outer side, and the positive Z-axis side is the inner side.

[0063] The light-shielding housing 1 has a plurality of third through-holes 101 that penetrate through its inner and outer sides in the Z-axis direction. 14 of the plurality of third through-holes 101 are distributed along the stroke extension direction of the number "88" (see Figure 5 , where 7 third through-holes 101 are distributed along the stroke extension direction of one number "8", and the other 7 third through-holes 101 are distributed along the stroke extension direction of the other number "8").

[0064] The display front shell layer 2 is a light-transmissible layer. The display front shell layer 2 is attached to the outer surface (the negative Z-axis side surface) of the light-shielding housing 1 in a pasting manner and covers the orifices of the third through-holes 101 on the outer surface of the light-shielding housing 1 (the negative Z-axis end orifices of the third through-holes 101). The display front shell layer 2 may specifically be a light-transmissible sheet-like structure such as a PET film, tinted glass, or an acrylic sheet. And the inner surface of the display front shell layer 2 is in contact with the outer surface of the light-shielding housing 1. The thickness of the display front shell layer 2 is 1 mm. It is preferably set that the display front shell layer 2 is made of a semi-transparent material.

[0065] The second potting fence 3 is integrally injection-molded on the inner surface (the positive Z-axis side surface) of the light-shielding housing 1 and protrudes inward (the positive Z-axis side) from the inner surface of the light-shielding housing 1. Each of the third through-holes 101 is located within the area surrounded by the second potting fence 3.

[0066] The second light-shielding frame 4 is fixedly installed on the positive Z-axis side of the light-shielding housing 1 and is located within the area surrounded by the second potting fence 3. The second light-shielding frame 4 has a plurality of fourth through-holes 401 penetrating in the Z-axis direction. Fourteen of the plurality of fourth through-holes 401 are distributed along the stroke extension direction of the number "88". Each third through-hole 101 corresponds to each fourth through-hole 401 one by one. The third through-hole 101 and the corresponding fourth through-hole 401 are butt-connected and communicate with each other in the Z-axis direction to form a second light-transmitting hole.

[0067] The second light-transmitting material 5 is injected in a fluid state and cured to form in the second light-transmitting hole. The positive Z-axis end orifice of the second light-transmitting hole (i.e., the second orifice, which is also the positive Z-axis end orifice of the fourth through-hole 401) is exposed outside the second light-transmitting material 5.

[0068] Please refer to Figures 3 to 7 , during the production of the housing assembly 100 of this embodiment, on the basis that the second potting fence 3 is integrally formed on the inner surface of the light-shielding housing 1, first, the display face shell layer 2 is pasted on the outer surface of the light-shielding housing 1. The orifice of the third through-hole 101 on the outer surface (negative Z-axis side surface) of the light-shielding housing 1 is blocked by the display face shell layer 2, and the combination of the formed light-shielding housing 1, the second potting fence 3, and the display face shell layer 2 is placed in a state where the XOY plane is horizontal and the positive Z-axis is vertically upward, so that the second potting fence 3, the inner surface of the light-shielding housing 1, and the inner surface of the display face shell layer 2 surround and form a second potting groove area V2 with the notch facing upward. The third through-hole 101 is located in the second potting groove area V2 (see Figure 5 ), then the fluid second light-transmitting material 5 is injected into the second potting groove area V2, so that the fluid second light-transmitting material 5 submerges the third through-hole 101 (see Figure 6 ), and then, before the second light-transmitting material 5 is cured, the second light-shielding frame 4 is installed in the second potting groove area V2, so that the negative Z-axis end of the fourth through-hole 401 is immersed in the second light-transmitting material 5 and is butt-connected and communicates with the positive Z-axis end of the corresponding third through-hole 101. The positive Z-axis end of the fourth through-hole 401 is exposed outside the second light-transmitting material 5. After that, the second light-transmitting material 5 is cured (see Figure 3 and Figure 4 ), and the second light-shielding frame 4 is fixed in the second potting groove area V2 under the action of the cured second light-transmitting material 5.

[0069] Of course, during the production of the housing assembly 100 of this embodiment, other operations can also be added as needed. For example, the bubbles in the fluid second light-transmitting material 5 can also be removed by means such as vacuum pumping.

[0070] The second light-shielding frame 4 of the present embodiment is fixed in the second potting groove area V2 by the cured second light-transmitting material 5. Optionally, in other embodiments of the present utility model, the second light-shielding frame can be fixedly connected to the light-shielding shell or to the second potting fence by other existing methods such as snaps, screws, and gluing when the second light-transmitting material has not yet cured.

[0071] The second potting fence 3 in the present embodiment is integrally injection molded on the inner surface of the light-shielding shell 1. Optionally, in other embodiments of the present invention, the second potting fence and the light-shielding shell can also be set as different parts. For example, the second potting fence is fixedly installed on the inner surface of the light-shielding shell by gluing or the like and is sealed with the inner surface of the light-shielding shell. For another example, the second potting fence is fixed on the inner surface of the light-shielding shell by secondary injection molding (in this case, the combination of the second potting fence and the light-shielding shell is an integrated structure obtained by secondary injection molding). Of course, the second potting fence can also be formed on-site by a paste-like material on the inner surface of the light-shielding shell. For example, when the light-shielding shell is placed with the inner surface facing upward, the inner surface of the light-shielding shell is enclosed along a preset closed trajectory ( It is hoped that the edge contour trajectory of the second potting fence will be formed, and the paste material is extruded to form the second potting fence. Moreover, after the second light-transmitting material is solidified, the second potting fence can also be removed, so that the second potting fence is no longer present in the completed shell assembly. Of course, it is preferred to adopt the solution of the present embodiment to integrally injection mold the second potting fence 3 on the inner surface of the light-shielding shell 1. This is not only conducive to eliminating the installation process of the second potting fence 3 and simplifying the production process of the shell assembly 100, but also conducive to ensuring that the second potting fence 3 and the light-shielding shell 1 will not leave a fitting gap, and the fluid second light-transmitting material 5 will not leak out from the gap between the second potting fence 3 and the light-shielding shell 1 after being injected into the second potting groove area V2, which is conducive to improving the yield rate of the shell assembly 100.

[0072] In this embodiment, before injecting the second light-transmitting material 5 into the second potting groove area V2, the display surface shell layer 2 is attached to the outer surface of the light-shielding housing 1, and the hole opening of the third through hole 101 on the outer surface of the light-shielding housing 1 is blocked by the display surface shell layer 2, and the display surface shell layer 2 remains on the outer surface of the light-shielding housing 1 after the second light-transmitting material 5 is cured. This enables the second light-transmitting material 5 to contact the inner surface of the display surface shell layer 2 when it is in a fluid state, which is conducive to ensuring good fitting at all parts where the second light-transmitting material 5 cooperates with the display surface shell layer 2, is conducive to making the light directly enter the display surface shell layer 2 after passing out of the second light-transmitting material 5, reducing the loss of light during the propagation from the second light-transmitting material 5 to the display surface shell layer 2, and is conducive to improving the display effect; Optionally, in other embodiments of the present invention, a special flow-blocking structure can also be used during the production of the housing assembly to block the hole opening of the third through hole on the outer surface of the light-shielding housing, and the flow-blocking structure is removed after the second light-transmitting material is cured, and then the display surface shell layer is reattached to the outer surface of the light-shielding housing, so as to form a lit display pattern that can be observed from the outside on the display surface shell layer when a light source (such as the LED light source 9 described later) is opened inside the housing assembly (at this time, the outer surface of the display surface shell layer constitutes the outer surface of the housing assembly), and the contour of the display pattern corresponds to the contour of the hole opening at the negative Z-axis end of the third through hole. In a further solution, the display surface shell layer can also be cancelled, that is, after removing the flow-blocking structure, the display surface shell layer is no longer attached to the outer surface of the light-shielding housing. In this way, when a light source is opened inside the housing assembly, the lit display pattern is directly formed on the outer surface of the light-shielding housing by the second light-transmitting material. Of course, in the housing assembly produced in this way, the outer surface of the light-shielding housing constitutes the outer surface of the housing assembly, and the contour of the display pattern is the contour of the hole opening at the negative Z-axis end of the third through hole, and the housing assembly no longer has a display surface shell layer. Preferably, the flow-blocking structure is in the form of a thin film, and the inner surface of the flow-blocking structure fits the outer surface of the light-shielding housing, which is convenient for making the outer surface of the cured second light-transmitting material flush with the outer surface of the light-shielding housing. Of course, more preferably, the flow-blocking structure is a flexible film, which is convenient for making the inner surface of the flow-blocking structure fit well with the outer surface of the light-shielding housing, and thus is conducive to better blocking the hole opening of the third through hole on the outer surface of the light-shielding housing and is conducive to better making the outer surface of the cured second light-transmitting material flush with the outer surface of the light-shielding housing. Of course, the specific form of the flow-blocking structure can also be set with reference to the surface film pasting (such as the pasted plastic film) in the existing digital tube production process, which will not be elaborated here.

[0073] Preferably, in addition to attaching the display face shell layer 2 to the outer surface of the light-shielding housing 1 by conventional means such as pasting, in other embodiments of the present invention, the display face shell layer can also be attached to the outer surface (the negative Z-axis side surface of the light-shielding housing) of the light-shielding housing by in-mold insert injection molding. The display face shell layer covers the negative Z-axis end orifice of the third through-hole and seals the negative Z-axis end orifice of the third through-hole. The in-mold insert injection molding method is beneficial to making the display face shell layer fit more closely with the outer surface of the light-shielding housing, so that the display face shell layer can better seal the orifice of the third through-hole. Moreover, the in-mold insert injection molding method can form a display face shell layer with a relatively thin thickness. For example, the thickness of the display face shell layer can be set to relatively thin thicknesses such as 0.1 mm, 0.125 mm, 0.175 mm, 0.188 mm, 0.2 mm, etc., which is beneficial to reducing the stray light in the display face shell layer and making the outline of the display pattern clearer. Of course, since in this embodiment, the display face shell layer is attached to the outer surface of the light-shielding housing by in-mold insert injection molding, and since the second potting fence of this embodiment can also be integrally injection-molded with the light-shielding housing, the combination of the light-shielding housing, the second potting fence, and the display face shell layer can also be formed during the production stage of the light-shielding housing, rather than assembling the combination of the light-shielding housing, the second potting fence, and the display face shell layer after each of them is produced, which is beneficial to simplifying the production process and technological process of the outer shell assembly.

[0074] The display face shell layer formed by in-mold insert injection molding is not easily faded due to usage operations such as friction during long-term use.

[0075] Preferably, the second light-shielding frame 4 further has a plurality of third drainage channels 402 penetrating in the Z-axis direction. The third drainage channels 402 are offset from the third through-hole 101 in the Z-axis direction (similarly, the third drainage channels 402 are offset from the first light-transmitting holes described later in the Z-axis direction). The fourth through-hole 401, the third through-hole 101, and the third drainage channels 402 are all filled with a second light-transmitting material 5 injected in a fluid state and cured. During the process of installing the second light-shielding frame 4 into the second potting groove area V2 in this embodiment, the second light-transmitting material 5 in the second potting groove area V2 enters the fourth through-hole 401 and the third drainage channels 402 from the negative Z-axis end from bottom to top under the extrusion of the second light-shielding frame 4. By providing the third drainage channels 402, it is beneficial to accelerate the release of the pressure received by the second light-transmitting material 5, thereby reducing the resistance of the second light-transmitting material 5 to the installation of the second light-shielding frame 4 into the second potting groove area V2 and reducing the difficulty of installing the second light-shielding frame 4 into the second potting groove area V2.

[0076] Optionally, in other embodiments of the present utility model, a fourth drainage channel (not shown in the figure) may also be provided. The fourth drainage channel is formed between the inner peripheral wall surface of the second light-shielding frame and the second potting fence. The fourth drainage channel also communicates with both sides of the second light-shielding frame along the Z-axis direction. The position of the fourth drainage channel is offset from that of the third through-hole in the Z-axis direction (similarly, the position of the fourth drainage channel is offset from that of the first light-transmitting hole described later in the Z-axis direction). In this way, during the process of installing the second light-shielding frame into the second potting groove area, the second light-transmitting material can also enter the fourth drainage channel, which further helps to reduce the resistance of the second light-transmitting material to the installation of the second light-shielding frame into the second potting groove area and reduces the difficulty of installing the second light-shielding frame into the second potting groove area. Of course, the third drainage channel and the fourth drainage channel can also be cancelled. In this case, during the process of installing the second light-shielding frame into the second potting groove area, the second light-transmitting material is only discharged along the positive Z-axis direction into the fourth through-hole.

[0077] As for the specific positions of the third drainage channel and the fourth drainage channel, they can be reasonably set according to the distribution of the third through-holes and the need to evenly accommodate the second light-transmitting material, which will not be elaborated here.

[0078] Preferably, the cooperation between the second light-shielding frame 4 and the light-shielding housing 1 has a second positioning structure. The second positioning structure in this embodiment is the inner peripheral wall surface of the second potting fence 3 and the outer peripheral wall surface of the second light-shielding frame 4. The contact and cooperation between the inner peripheral wall surface of the second potting fence 3 and the outer peripheral wall surface of the second light-shielding frame 4 are used to position the cooperation position between the light-shielding housing 1 and the second light-shielding frame 4 in the direction perpendicular to the Z-axis. Optionally, in other embodiments of the present utility model, the second positioning structure includes a second positioning convex portion integrally formed on the light-shielding housing and a second positioning concave portion integrally formed on the second light-shielding frame. The second positioning convex portion is a columnar structure extending from the inner side surface of the light-shielding housing towards the positive Z-axis direction, and the second positioning concave portion is a hole-like structure extending along the Z-axis direction. The second positioning convex portion is inserted into the second positioning concave portion along the positive Z-axis direction. Of course, similarly, the second positioning convex portion can be provided on the second light-shielding frame, and the second positioning concave portion can be provided on the light-shielding housing.

[0079] In the light-shielding housing 1 of this embodiment, a second slot 102 recessed toward the negative Z-axis is formed on the inner surface (the positive Z-axis side surface). The extension trajectory of the second slot 102 on the inner surface of the light-shielding housing 1 respectively surrounds the positive Z-axis end orifices of the foregoing third through-holes 101 (that is, each third through-hole 101 is respectively located in a different surrounding circle formed by the separation of the second slot 102). A second insertion protrusion 403 protruding toward the negative Z-axis is formed at the negative Z-axis end of the second light-shielding bracket 4. The extension trajectory of the second insertion protrusion 403 matches the extension trajectory of the second slot 102. The extension trajectory of the second insertion protrusion 403 respectively surrounds the negative Z-axis end orifices of the fourth through-holes 401. The second insertion protrusion 403 is inserted into the second slot 102 along the negative Z-axis. The cooperation between each group of third through-holes 101 and fourth through-holes 401 is separated by the cooperation between the second insertion protrusion 403 and the second slot 102. In this embodiment, the groove wall of the second slot 102 and the second insertion protrusion 403 both constitute light-shielding walls. The arrangement of the second insertion protrusion 403 and the second slot 102 is beneficial to reducing the leakage of light between the light-shielding housing 1 and the second light-shielding bracket 4. Optionally, in other embodiments of the present utility model, the second insertion protrusion may also be formed on the inner surface of the light-shielding housing, and the second slot may be formed at the negative Z-axis end of the second light-shielding bracket. The concavo-convex structure provided around the negative Z-axis end orifice of the fourth through-hole on the second light-shielding bracket constitutes a part of the negative Z-axis end hole wall of the fourth through-hole. The concavo-convex structure provided around the positive Z-axis end orifice of the third through-hole on the inner surface of the light-shielding housing constitutes a part of the inner surface of the light-shielding housing. The butt-joint of the two concavo-convex structures also constitutes the butt-joint of the negative Z-axis end hole wall of the fourth through-hole and the inner surface of the light-shielding housing. The arrangement of the concavo-convex structure is beneficial to reducing the leakage of light during the process of the light propagating from the fourth through-hole to the third through-hole. Of course, the second insertion protrusion and the second slot may also be cancelled, so that the positive Z-axis end hole wall of the third through-hole (the end surface of which constitutes a part of the inner surface of the light-shielding housing) is butt-jointed with the negative Z-axis end hole wall of the fourth through-hole in a manner of end surface contact. In this way, the structures of the light-shielding housing and the second light-shielding bracket are both simpler.

[0080] In this embodiment, the front shell (outer shell) of the electronic product is set as the light-shielding shell 1, and a third through hole 101 is opened on the light-shielding shell 1. The light emitted by the light source inside the outer shell assembly 100 is propagated to the outer surface of the light-shielding shell 1 through the combination of the fourth through hole 401 and the third through hole 101 to form a display pattern. The combination of the light-shielding shell 1 and the second light-shielding frame 4 is used as the shell-side light-shielding structure, and the combination of the third through hole and the fourth through hole in butt communication forms the second light-transmitting hole; Optionally, in other embodiments of the present invention, the front shell can also be set as a light-transmitting shell, and the third through hole opened on the front shell is cancelled. In this embodiment, only the second light-shielding frame is used as the shell-side light-shielding structure, only the fourth through hole is used as the second light-transmitting hole, and the light-transmitting shell (outer shell) is used as the display surface shell layer. The end wall of the negative Z-axis of the fourth through hole is butted against the inner surface of the light-transmitting shell, and the outer surface of the light-transmitting shell constitutes the outer surface of the outer shell assembly. The light emitted by the light source turned on inside the outer shell assembly passes through the fourth through hole and is propagated to the light-transmitting shell to form a display pattern that the user can observe on the outside of the outer shell assembly. The contour of the display pattern corresponds to the contour of the end opening of the negative Z-axis of the fourth through hole. Since the third through hole is cancelled in the front shell of this embodiment, not only is it unnecessary to provide an additional structure (such as the aforementioned flow-blocking structure) to prevent the fluid-like second light-transmitting material from leaking through the third through hole, which is beneficial to simplifying the production process of the outer shell assembly and reducing the production difficulty of the outer shell assembly, but also there is no risk of the fluid-like second light-transmitting material leaking through the third through hole, which is beneficial to improving the production yield and quality of the outer shell assembly; Preferably, the front shell is a semi-transparent shell. On the one hand, when a light source is turned on inside the outer shell assembly, a lit display pattern can be formed on the semi-transparent shell. On the other hand, when the light source is not turned on inside the outer shell assembly, the inner structure can be blocked and hidden through the semi-transparent shell, making it difficult for the user to observe the inner structure (such as the inner second light-shielding frame) through the semi-transparent shell, which is beneficial to making the appearance structure of the outer shell assembly simple, and thus beneficial to making the appearance structure of the corresponding electronic product simple; Specifically, the semi-transparent shell can be integrally injection-molded from a semi-transparent material, or can be formed by combining a light-transmitting shell and a semi-transparent film attached to its outer surface. Moreover, the semi-transparent film can be obtained by means such as screen printing, spraying, in-mold insert injection molding, etc.

[0081] In this embodiment, the second potting fence 3 protruding from the inner surface of the light-shielding shell 1 in the positive Z-axis direction participates in enclosing to form the second potting groove area V2, and the second potting fence 3 extends along the outer edge of the second potting groove area V2; Optionally, in other embodiments of the present invention, the second potting fence 3 of this embodiment can also be cancelled, and by recessing a part of the outer shell (such as the light-shielding shell) in the negative Z-axis direction, the second potting groove area is formed. At this time, it is preferably that the part of the outer shell forming the second potting groove area is an integral structure, which is beneficial to simplifying the forming process of the second potting groove area and reducing the leakage risk of the fluid-like second light-transmitting material.

[0082] Since in the process of manufacturing the housing assembly 100 in this embodiment, the second potting groove area V2 is formed, and the fluid second light-transmitting material 5 is first injected into the second potting groove area V2, and then the second light-shielding frame 4 is installed in the second potting groove area V2 before the second light-transmitting material 5 is cured. Therefore, compared with the technical solution that needs to inject the second light-transmitting material into each third through-hole 101 separately, since the size of the second potting groove area V2 in this embodiment is often larger than the size of a single third through-hole 101 of the second light-shielding frame 4 therein, the requirements for process accuracy and the like of injecting the second light-transmitting material 5 into the second potting groove area V2 in this embodiment are lower, the potting process difficulty of the second light-transmitting material 5 is lower. Moreover, regardless of how many combinations of the third through-holes 101 and the fourth through-holes 401 there are in this embodiment, only one injection of the second light-transmitting material 5 is required to fill each of the third through-holes 101 with the second light-transmitting material 5, and to fill the negative Z-axis ends of each of the fourth through-holes 401 with the second light-transmitting material 5 after the second light-shielding frame 4 is installed in the second potting groove area V2. This embodiment does not need to adjust the injection process of the second light-transmitting material 5 according to the number of combinations of the third through-holes 101 and the fourth through-holes 401, and does not need to perform multiple injections when the number of combinations of the third through-holes 101 and the fourth through-holes 401 is large, which is beneficial to improving the stability of the injection process, and is beneficial to improving the injection efficiency of the second light-transmitting material 5, and is beneficial to simplifying the production process of the housing assembly 100.

[0083] Optionally, in other embodiments of the present invention, the second potting groove area can also be cancelled. Of course, in this embodiment, the fluid second light-transmitting material needs to be injected into each second light-transmitting hole respectively. And in this embodiment, only the light-shielding housing can be used as the shell-side light-shielding structure and as the outer shell, or only the separate second light-shielding frame can be used as the shell-side light-shielding structure, and the light-transmitting housing can be used as the outer shell.

[0084] The potting thickness dimension of the cured second light-transmitting material 5 in the second light-transmitting hole in this embodiment is 8 mm; optionally, in other embodiments of the present invention, the potting thickness dimension of the second light-transmitting material 5 in the second light-transmitting hole can also be set to other dimensions greater than or equal to 2 mm, such as 3 mm, 5 mm, etc.

[0085] Regarding the LED display function module

[0086] Please refer to Figure 2 、 Figure 3 and Figures 8 to 10, the LED display function module 200 of this embodiment includes a circuit board 6, a first potting fence 7, a first light-shielding bracket 8, a plurality of LED light sources 9, and a first light-transmitting material 10. The normal line of the main surface of the circuit board 6 is along the Z-axis direction. The LED light sources 9 and the first potting fence 7 are both fixed on the main surface (the first main surface 601) on the negative Z-axis side of the circuit board 6. Fourteen of the plurality of LED light sources 9 are distributed along the stroke extension direction of the number "88".

[0087] The main structure of the first potting fence 7 is in a square shape. A pair of its side frames are distributed along the Y-axis direction and each extends along the X-axis direction, and the other pair of side frames are distributed along the X-axis direction and each extends along the Y-axis direction. The end surface of the positive Z-axis end of the first potting fence 7 is a plane with a normal line along the Z-axis direction, and it is closely attached to the first main surface 601 of the circuit board 6, and the circuit board 6 and the first potting fence 7 are in good sealing fit through an adhesive method; Optionally, in other embodiments of the present invention, the first potting fence may also be connected with a sealing gasket at the positive Z-axis end (the sealing gasket at this time can be regarded as a part of the first potting fence), and the sealing fit is carried out between the sealing gasket and the first main surface of the circuit board. In addition, the shape of the first potting fence can also be set to other shapes according to needs, which will not be elaborated here.

[0088] A light-shielding base 701 is integrally formed within the area surrounded by each side frame of the first potting fence 7. The light-shielding base 701 is located at the positive Z-axis end of the first potting fence 7. The circuit board 6, the light-shielding base 701, and the first light-shielding bracket 8 are fixedly connected in sequence along the negative Z-axis direction. In this embodiment, the combination of the light-shielding base 701 and the first light-shielding bracket 8 constitutes a board-side light-shielding structure.

[0089] The light-shielding base 701 is provided with a plurality of first through holes 702 that penetrate along the Z-axis direction. Fourteen of the plurality of first through holes 702 are distributed along the stroke extension direction of the number "88". The end wall surface of the positive Z-axis end of the light-shielding base 701 is closely fitted with the first main surface 601, and each first through hole 702 corresponds to an LED light source 9.

[0090] The first light-shielding bracket 8 is provided with a plurality of second through holes 801 that penetrate along the Z-axis direction. Fourteen of the plurality of second through holes 801 are distributed along the stroke extension direction of the number "88". Each first through hole 702 and each second through hole 801 are in one-to-one correspondence and are connected and communicated along the Z-axis direction.

[0091] See Figures 8 to 10, in the process of manufacturing the LED display function module of this embodiment, first, the LED light source 9 and the first potting fence 7 are fixedly installed on the first main surface 601, and the circuit board 6 is placed in a state where the first main surface 601 faces upward (the negative Z-axis faces upward), so that the first main surface 601 and the first potting fence 7 jointly enclose a first potting groove area V1 with the notch facing upward (including the space enclosed by the main surface on the negative Z-axis side of the light-shielding base 701 and the respective side frames of the first potting fence 7, and including the first through hole 702). Then, a fluid first light-transmitting material 10 is injected into the first potting groove area V1 to submerge each LED light source 9 and each first through hole 702. Then, before the first light-transmitting material 10 is cured, the first light-shielding frame 8 is loaded into the first potting groove area V1 from top to bottom (the positive Z-axis direction shown in the figure), so that the positive Z-axis end orifice of each second through hole 801 sinks into the first light-transmitting material 10 and is in butt communication with the corresponding first through hole 702 to form a first light-transmitting hole (at this time, a part of the hole cavity near the positive Z-axis end of the second through hole 801 is filled with the first light-transmitting material 10, and the negative Z-axis end orifice of the second through hole 801 is exposed outside the first light-transmitting material 10). After that, the first light-transmitting material 10 is cured.

[0092] Preferably, the first light-shielding frame 8 has a plurality of first drainage channels 804 penetrating in the Z-axis direction. The first drainage channels 804 are staggered with the first through holes 702 in the Z-axis direction (similarly, the first drainage channels 804 are staggered with the aforementioned second light-transmitting holes in the Z-axis direction). In this way, during the process of loading the first light-shielding frame 8 into the first potting groove area V1, the first light-transmitting material 10 in the first potting groove area V1 enters the second through hole 801 and the first drainage channels 804 from the negative Z-axis end from bottom to top under the extrusion of the first light-shielding frame 8. By providing the first drainage channels 804, it is beneficial to accelerate the release of the pressure on the first light-transmitting material 10, thereby reducing the resistance of the first light-transmitting material 10 to the loading of the first light-shielding frame 8 into the first potting groove area V1 and reducing the difficulty of loading the first light-shielding frame 8 into the first potting groove area V1.

[0093] Optionally, in other embodiments of the present invention, a second drainage channel (not shown in the figure) may also be provided. The second drainage channel is formed between the first light-shielding frame and the inner peripheral wall of the first potting fence. The second drainage channel also communicates with both sides of the first light-shielding frame in the Z-axis direction. The second drainage channel is staggered with the first through hole in the Z-axis direction. In this way, during the process of loading the first light-shielding frame into the first potting groove area, the first light-transmitting material can also enter the second drainage channel, which is further beneficial to reducing the resistance of the first light-transmitting material to the loading of the first light-shielding frame into the first potting groove area and reducing the difficulty of loading the first light-shielding frame into the first potting groove area; of course, the first drainage channel and the second drainage channel can also be cancelled, so that during the process of loading the first light-shielding frame into the first potting groove area, the first light-transmitting material is only discharged upward from the negative Z-axis to the second through hole.

[0094] As for the specific positions of the first drainage channel and the second drainage channel, they can be reasonably set according to the distribution of the first through holes and the need to evenly accommodate the first light-transmitting material, which will not be elaborated here.

[0095] On the positive Z-axis end face of the first potting fence 7 (including the light-shielding base 701), there is a first positioning convex portion 704 protruding towards the positive Z-axis. The first positioning convex portion 704 is cylindrical. The circuit board 6 has a first positioning concave portion 602, and the first positioning concave portion 602 is a through hole that penetrates the circuit board 6 along the Z-axis direction. The first positioning convex portion 704 is inserted into the first positioning concave portion 602 along the positive Z-axis. The positive Z-axis end of the first positioning convex portion 704 extends to the positive Z-axis side of the circuit board 6, and by thermally melting and riveting the positive Z-axis end of the first positioning convex portion 704, the first positioning convex portion 704 cannot be disengaged from the first positioning concave portion 602 along the negative Z-axis (the illustrated first positioning convex portion 704 is the state before thermally melting and riveting), so as to realize the positioning of the first potting fence 7 and the circuit board 6 in the XOY plane direction and fasten the first potting fence 7 to the circuit board 6.

[0096] Moreover, in this embodiment, thermally melting and riveting the positive Z-axis end of the first positioning convex portion 704 to the positive Z-axis side of the circuit board 6 is beneficial to improving the tightness of the fixed connection between the first potting fence 7 and the circuit board 6. On the one hand, this is beneficial to reducing the risk of light leakage between the light-shielding base 701 and the circuit board 6. On the other hand, it is also beneficial to reducing the risk of the first light-transmitting material 10 leaking through the first potting fence 7 and the circuit board 6, and reducing the risk of the fluid first light-transmitting material 10 leaking through the first positioning concave portion 602.

[0097] In this embodiment, the first positioning convex portion 704 and the first positioning concave portion 602 are not only used to position the cooperation between the first potting fence 7 and the circuit board 6, but also used to fixedly connect the first potting fence 7 and the circuit board 6. Optionally, in other embodiments of the present invention, the negative Z-axis end of the first positioning convex portion may not be thermally melted and riveted. At this time, the cooperation between the first positioning convex portion and the first positioning concave portion is only used to position the cooperation between the first potting fence and the circuit board. Of course, at this time, the first positioning concave portion may not be a through hole, and the first positioning convex portion does not need to penetrate the circuit board. Moreover, other methods need to be used to fixedly connect the circuit board and the first potting fence, for example, existing other methods such as buckles and adhesives can be used to fixedly connect the first potting fence and the circuit board.

[0098] In this embodiment, the cooperation between the first positioning convex portion 704 and the first positioning concave portion 602 constitutes the first positioning structure, and the number of the first positioning structures is seven groups; alternatively, in other embodiments of the present invention, the number and position of the cooperation between the first positioning convex portion and the first positioning concave portion can also be set according to actual needs, or the first positioning structure can also be set with reference to other existing structures, or the first positioning structure between the circuit board and the first potting fence can be cancelled, and an external tooling such as a jig can be used to ensure the accurate positioning cooperation between the first potting fence and the circuit board.

[0099] In this embodiment, the light-shielding base 7 is formed with a first insertion convex portion 703 protruding toward the negative Z-axis on the negative Z-axis side surface, and the extending trajectory of the first insertion convex portion 703 surrounds the negative Z-axis end orifices of the first through holes 702 respectively (that is, each first through hole 702 is respectively located in a different surrounding circle formed by being separated by the first insertion convex portion 703). The first light-shielding frame 8 is formed with a first insertion slot 802 recessed toward the negative Z-axis at the positive Z-axis end. The extending trajectory of the first insertion slot 802 matches the extending trajectory of the first insertion convex portion 703. The extending trajectory of the first insertion slot 802 surrounds the positive Z-axis end orifices of the second through holes 801 respectively. The first insertion convex portion 703 is inserted into the first insertion slot 802 along the negative Z-axis. The cooperation between each group of the first through holes 702 and the second through holes 801 is separated by the cooperation between the first insertion convex portion 703 and the first insertion slot 802. In this embodiment, the slot wall of the first insertion slot 802 and the first insertion convex portion 703 both constitute light-shielding walls. The cooperation between the first insertion slot 802 and the first insertion convex portion 703 is beneficial to reducing the leakage of light between the light-shielding base 7 and the first light-shielding frame 8, and is beneficial to reducing the light crosstalk phenomenon between different first light-transmitting holes; alternatively, in other embodiments of the present invention, the first insertion convex portion can also be formed at the positive Z-axis end of the first light-shielding frame, and the first insertion slot can be formed at the negative Z-axis end of the light-shielding base. Of course, the first insertion convex portion and the first insertion slot can also be cancelled. For example, the negative Z-axis end hole wall of the first through hole and the positive Z-axis end hole wall of the second through hole can be directly butted in a way that the end surfaces are in contact.

[0100] Optionally, in other embodiments of the present utility model, the light-shielding substrate on the first potting fence can also be cancelled. At this time, only the first light-shielding frame is used as the light-shielding structure on the board side. The first light-transmitting holes are only composed of the second through holes opened in the first light-shielding frame. The first potting groove area is formed by enclosing the border of the first potting fence and the first main surface. The positive Z-axis end of the first light-shielding frame is directly butted against the first main surface. Of course, further, the entire first potting fence can also be cancelled. In this way, when producing the LED display function module of this embodiment, first, the LED light source and the light-shielding structure on the board side (such as the first light-shielding structure) are fixedly installed on the first main surface, and the circuit board is placed in a state where the first main surface faces upward. Then, fluid first light-transmitting material is injected into each first light-transmitting hole respectively, and the LED display function module is formed after the first light-transmitting material is cured. Of course, it is preferably to adopt the technical solution with the first potting fence 7 in this embodiment. In this way, during the process of injecting the first light-transmitting material 10, since the cross-sectional size of the injection area is larger (the cross-sectional size of the first potting groove area V1 is larger than the cross-sectional size of each first light-transmitting hole), it is beneficial to reduce the injection difficulty of the first light-transmitting material 10. And, in this way, no matter how many first light-transmitting holes there are, the entire production process only needs to inject the first light-transmitting material 10 once, which is beneficial to simplifying the production process of the LED display function module.

[0101] Specifically, the LED light source 9 in this embodiment is an LED lamp bead. Optionally, in other embodiments of the utility model, the LED light source is preferably an LED chip. The LED chip can be installed on the metal electrodes of the circuit board in a flip-chip or a face-up mounting manner. For example, when the LED chip is mounted face-up, it is connected to the metal electrodes on the circuit board through metal wires. The specific mounting method of the LED chip on the circuit board can refer to the existing technology and will not be elaborated here.

[0102] Regarding LED display devices and electronic products

[0103] The LED display device of the present embodiment includes a shell component 100 and an LED display function module 200 fixed on the inner side of the shell component 100 (the positive side of the Z axis). After the shell component 100 and the LED display function module 200 are respectively produced, in the process of producing the LED display device and the electronic product of the present embodiment, the shell component 100 and the LED display function module 200 are connected along the Z axis direction, so that each first light-transmitting hole and each second light-transmitting hole are connected and communicated with each other in a one-to-one correspondence along the Z axis direction to form a light-guiding channel, that is, each third through hole 101, each fourth through hole 401, each second through hole 801 and each first through hole 702 of the present embodiment are connected and communicated with each other in a one-to-one correspondence along the positive direction of the Z axis to form a light-guiding channel, and 14 of the multiple light-guiding channels are distributed along the extension direction of the strokes of the number "88". When the LED light source is turned on, the light is transmitted to the display surface shell layer 2 through the light-guiding channel, and a lighted "88" (display pattern) that can be observed on the outside of the shell component 100 is formed on the display surface shell layer.

[0104] Specifically, the hole opening at the negative end of the first light-transmitting hole in the Z-axis direction (the hole opening at the negative end of the second through hole 801 in the Z-axis direction) is the first hole opening, and the hole opening at the positive end of the second light-transmitting hole in the Z-axis direction (the hole opening at the positive end of the fourth through hole 401 in the Z-axis direction) is the second hole opening. The first hole opening and the second hole opening are connected and connected along the Z-axis direction. The second light-shielding frame 4 is formed with a third slot 404 recessed toward the negative direction of the Z-axis at the positive end of the Z-axis, and the extension trajectory of the third slot 404 surrounds each second hole opening respectively. The negative end of the first light-shielding frame 8 is formed with a third protrusion 803 protruding toward the negative direction of the Z-axis, and the extension trajectory of the third protrusion 803 matches the extension trajectory of the third slot 404. The extension trajectory of the third protrusion 803 surrounds each first hole opening respectively. The third protrusion 803 is formed along the Z-axis direction. The axis is inserted into the third slot 404 in the negative direction, and the cooperation between each group of second openings and the first openings is separated by the cooperation between the third insertion protrusion 803 and the third slot 404. In this embodiment, the groove wall of the third slot 404 constitutes a second light-shielding wall 405, and the third insertion protrusion 803 constitutes a first light-shielding wall. The second light-shielding wall 405 extends around each second opening, and the second light-shielding wall 405 surrounds each second opening respectively. The first light-shielding wall extends around each first opening, and the first light-shielding wall surrounds each first opening respectively. The second light-shielding wall 405 extending around the second opening is inserted into the inner and outer peripheries of the first light-shielding wall extending around the corresponding first opening, and different light-guiding channels are blocked by the cooperation between the corresponding second light-shielding wall 405 and the first light-shielding wall.

[0105] In this embodiment, the extending path of the first light-shielding wall is a closed path extending around the first orifice, and the extending path of the second light-shielding wall 405 is a closed path extending around the second orifice. Optionally, in other embodiments of the present invention, the extending path of the first light-shielding wall may also have a notch. Of course, in this case, the first light-shielding wall can only prevent light leakage in some directions, and the performance of preventing light leakage / crosstalk will be reduced. Therefore, it is preferably to set the extending path of the first light-shielding wall as a closed path extending around the first orifice. Similarly, the extending path of the second light-shielding wall may also have a notch, and it is also preferably to set the extending path of the second light-shielding wall as a closed path extending around the second orifice.

[0106] Optionally, in other embodiments of the present invention, the forming manner of the first light-shielding wall is not limited to the third insertion protrusion, and the forming manner of the second light-shielding wall is not limited to the inner wall of the third slot. The first light-shielding wall and the second light-shielding wall may both be insertion protrusions extending around their respective orifices. The first light-shielding wall is inserted and fitted along the Z-axis direction on the inner circumference of the second light-shielding wall, or the first light-shielding wall is inserted and fitted along the Z-axis direction on the outer circumference of the second light-shielding wall. Of course, the forming and fitting manners of the first light-shielding wall and the second light-shielding wall may also refer to the Chinese patent application with the publication number CN118015931A, which will not be elaborated here.

[0107] Preferably, the cooperation between the LED display function module 200 and the housing assembly 100 has a third positioning structure, and the third positioning structure is used to position the relative cooperation position of the LED display function module 200 and the housing assembly 100 in the direction perpendicular to the Z-axis. In this embodiment, the relative cooperation position of the LED display function module 200 and the housing assembly 100 in the direction perpendicular to the Z-axis is positioned by the cooperation between the inner peripheral wall of the second potting fence 3 and the outer peripheral wall of the first potting fence 7. At this time, the cooperation between the first potting fence 7 and the second potting fence 3 constitutes the third positioning structure. Optionally, in other embodiments of the present invention, other structures may also be used as the third positioning mechanism. For example, the third positioning structure includes a cylindrical third positioning protrusion (not shown in the figure) and a circular hole-shaped third positioning recess. One of the third positioning protrusion and the third positioning recess is located on the LED display function module, and the other is located on the housing assembly. The third positioning protrusion is inserted into the third positioning recess along the Z-axis direction. The specific scheme of the cooperation between the third positioning protrusion and the third positioning recess can be set with reference to the cooperation between the first positioning protrusion 704 and the first positioning recess 602, which will not be elaborated here.

[0108] Optionally, in other embodiments of the present utility model, a colloidal light-shielding filler is adhered to the second light-shielding wall, and the light-shielding filler is filled between the second light-shielding wall and the first light-shielding wall. For example, the light-shielding filler is black latex. Before the operator fits and installs the LED display function module with the housing assembly, the first light-shielding wall is first immersed in the liquid black latex so that the liquid black latex adheres to the first light-shielding wall, and then the second light-shielding wall is inserted and fitted with the first light-shielding wall. The black latex is filled between the second light-shielding wall and the first light-shielding wall. The setting of the light-shielding filler is beneficial to further reducing the leakage of light between the LED display function module and the housing assembly. Moreover, as an adhesive, the liquid black latex can also fixedly connect the second light-shielding wall and the first light-shielding wall after curing, which is beneficial to improving the fitting stability between the second light-shielding wall and the first light-shielding wall. Of course, the light-shielding filler can be in the form of particles in addition to being colloidal. For example, the light-shielding filler is rubber particles. Also, the light-shielding filler can be adhered to the second light-shielding wall first, or the light-shielding filler can be adhered to both the second light-shielding wall and the first light-shielding wall, and then the second light-shielding wall is inserted and fitted with the first light-shielding wall so that the light-shielding filler is filled between the second light-shielding wall and the first light-shielding wall. Of course, the filling of the space between the second light-shielding wall and the first light-shielding wall by the light-shielding filler can be partial filling or full filling. As long as there is a light-shielding filler filled between the second light-shielding wall and the first light-shielding wall, it is beneficial to reduce the leakage and stray light between the second light-shielding wall and the first light-shielding wall.

[0109] Please refer to Figure 2 、 Figure 3 and Figure 9 , the circuit board 6 is the main control board of the electronic product in this embodiment. Optionally, in other embodiments of the present utility model, the circuit board can also be an independent board body electrically connected to the main control board of the electronic product.

[0110] The LED display function module 200 is fixedly installed on the front shell by screws (not shown in the figure). The front shell has a positioning and mounting post 103 that extends forward in the positive Z-axis direction in the mounting cavity V100. The screws penetrate the circuit board 6 from the positive Z-axis side of the circuit board 6 along the negative Z-axis, and then are threadedly engaged with the positioning and mounting post 103, thereby realizing the fixed connection between the LED display function module 200 and the front shell. After the circuit board 6 is fixedly installed on the front shell, the front shell and the rear shell 300 are fixedly connected by a snap-fastening method.

[0111] The first light-transmitting material 10 and the second light-transmitting material 5 in this embodiment can be, for example, light-transmitting potting materials commonly used in the LED display field, such as silicone potting glue, epoxy potting glue, polyurethane potting glue, ultraviolet potting glue, fluorescent glue, etc. They are in a fluid state in the storage state and will cure under certain conditions (such as ultraviolet light irradiation), and can be used for encapsulating LED light sources in the LED display field.

[0112] Preferably, a light diffusing agent for dispersing the propagation of light is mixed in the second light-transmitting material 5. The light diffusing agent can be, for example, fine particles of materials such as nano barium sulfate, calcium carbonate, and silicon dioxide. Of course, a light diffusing agent can also be mixed in the first light-transmitting material 10. More preferably, the light transmittance of the first light-transmitting material 10 is greater than that of the second light-transmitting material 5. For example, only the second light-transmitting material 5 is added with a light diffusing agent, while the first light-transmitting material 10 is not added with a light diffusing agent, or the proportion of the light diffusing agent added to the second light-transmitting material 5 is greater than the proportion of the light diffusing agent added to the first light-transmitting material 10. This is beneficial to reducing the light quantity loss during the propagation of light in the first light-transmitting material 10, and is also beneficial to guiding the light to the housing assembly 100 through the second light-transmitting material 5 to form a lighted display pattern.

[0113] Optionally, in other embodiments of the present invention, the cured second light-transmitting material forms a light guide column (for example, the second light-transmitting material is formed by curing a light guide material such as polymethyl methacrylate). When the LED light source is turned on, it guides the light to the housing assembly and forms a lighted display pattern on the housing assembly. This is beneficial to improving the brightness and uniformity of each part of the display pattern, and is also beneficial to ensuring that the boundary of the display pattern is clear. Preferably, in this embodiment, the first light-transmitting material is a light-transmitting potting material and is mixed with a light diffusing agent. In this way, the light emitted by the LED light source is dispersed and propagated through the first light-transmitting material, and is conducted to the housing assembly through the second light-transmitting material to form a lighted display pattern, which is further beneficial to improving the brightness uniformity of each part of the display pattern.

[0114] Regarding the technical effects

[0115] In this embodiment, the circuit board 6, the light-shielding base 701, the first light-shielding frame 8, the second light-shielding frame 4, and the light-shielding housing 1, and the display surface shell layer 2 are sequentially connected along the negative Z-axis. And between the circuit board 6 and the display surface shell layer 2, a light guide channel is formed by sequentially docking and communicating the first light-transmitting hole and the corresponding second light-transmitting hole along the negative Z-axis. The light emitted by the LED light source 9 is propagated to the display surface shell layer 2 through the corresponding light guide channel, so as to form a lighted display pattern on the display surface shell layer 2. For example, when all the 14 LED light sources 9 described above are turned on, the light of each LED light source 9 is propagated to the display surface shell layer 2 through the corresponding light guide channel, so as to form a lighted "88" character (display pattern) on the display surface shell layer 2.

[0116] In particular, in this embodiment, the second light-transmitting material 5 is poured into the second light-transmitting hole of the light-shielding structure on the shell side, and the first light-transmitting material 10 is poured into the first light-transmitting hole of the light-shielding structure on the board side.

[0117] Among them, since the second light-transmitting hole is injected with the second light-transmitting material 5, the second light-transmitting material 5 can be used to form a display pattern on the shell component 100, so that when the user observes the display pattern outside the shell component 100, it is beneficial to reduce the difference in display effects under different observation angles, which is beneficial to improve the user experience.

[0118] Furthermore, since the light-transmitting material is formed in the light-guiding channel, the present embodiment can flexibly set the thickness, transmittance and other properties of the light-transmitting material (such as the second light-transmitting material 5) to better meet the user's demand for uniform light dispersion and propagation without causing the light to exceed the range of the light-guiding channel in the direction perpendicular to the Z-axis. This is beneficial for concentrating the light generated by the LED light source 9 to the area where the display pattern is formed, which is beneficial for reducing light loss, improving the brightness of the display pattern, making the formed display pattern clear in outline, and also beneficial for making the brightness and darkness of the display pattern more uniform.

[0119] In addition, the present embodiment does not need to rely on the display surface shell layer 2 to disperse and propagate the light. Therefore, the present embodiment does not need to set the display surface shell layer 2 as a light diffusion film with a larger thickness in order to disperse the light evenly. The present embodiment can further reduce the stray light in the display surface shell layer 2 by setting a thinner display surface shell layer 2 (or even eliminating the display surface shell layer 2), thereby making the display pattern outline on the surface of the display surface shell layer 2 clearer.

[0120] In the present embodiment, the display surface shell layer 2 is made of a semi-transparent material, so that when the LED light source 9 is normally turned off, it is not easy for the user to observe its inner structure through the display surface shell layer 2. When the LED light source 9 is turned on, light can pass through the display surface shell layer 2 and form a lit display pattern on the outer surface of the display surface shell layer 2. This is beneficial for forming a lit display pattern on the outer shell component 100 when the LED light source 9 is turned on, and is also beneficial for making the appearance structure of the outer shell component more concise when the LED light source 9 is turned off. Of course, in other embodiments of the present invention, a display surface shell layer 2 with appropriate transmittance can also be selected as needed. For example, the transmittance of the display surface shell layer 2 can also be set to a degree that the user can observe its inner structure through the display surface shell layer 2 when the LED light source 9 is normally turned off.

[0121] In addition, in this embodiment, since the first light-transmitting material 10 is poured into the first light-transmitting holes of the light-shielding structure on the board side, on the one hand, this embodiment can reduce the loss of light quantity during the propagation in the light guide channel by selecting the first light-transmitting material 10 with a relatively large light transmittance (preferably, the light transmittance of the first light-transmitting material 10 is greater than that of air), which is conducive to improving the display brightness of the LED display device. Of course, this embodiment can also select the first light-transmitting material 10 that is convenient for the light to be scattered and propagated to further ensure the uniform brightness and darkness of the display pattern everywhere. On the other hand, the use of the first light-transmitting material 10 also creates conditions for this embodiment to select the LED chip as the LED light source (the first light-transmitting material 10 provides protection for the LED chip). Using the LED chip as the LED light source not only helps to reduce the cost of the LED display device, but also, the LED chips are often packaged in batches according to the production sequence. For the LED chips of the same or adjacent batches, due to the better consistency in production raw materials, processes and conditions, etc., they also have better consistency in terms of brightness, brightness attenuation law and service life. If the LED chips are used as the LED light source, it is convenient to use the LED chips of the same or adjacent batches in the same LED display device, which is conducive to making the performance of each LED light source in the same LED display device have good consistency in terms of brightness, brightness attenuation law and service life.

[0122] In this embodiment, the first orifice is set to be exposed outside the first light-transmitting material 10, and the second orifice is set to be exposed outside the second light-transmitting material 5. In this way, when producing the LED display device / electronic product, after the housing assembly 100 and the LED display function module 200 are each produced, the light guide through hole can be formed by connecting and communicating the first orifice and the second orifice, realizing the cooperative installation of the LED display function module 200 and the housing assembly 100, which is conducive to improving the production efficiency and flexibility of the LED display device and expanding the applicable range of the LED display device in this embodiment.

[0123] In this embodiment, the first orifice and the second orifice are docked by means of the insertion fit between the first light-shielding wall and the second light-shielding wall 405. This not only helps to reduce the leakage of light between the LED display function module 200 and the housing assembly 100, minimizing leakage and stray light during the propagation of light in the light guide channel, but also enables the relative mating position between the LED display function module 200 and the housing assembly 100 to be adjusted by varying the depth of the insertion fit between the first light-shielding wall and the second light-shielding wall 405, making the relative mating position between the LED display function module 200 and the housing assembly 100 more flexible and facilitating the reduction of the mating and installation difficulty between the LED display function module 200 and the housing assembly 100. Optionally, in other embodiments of the present invention, a buffer layer made of an elastic light-shielding material can also be used to dock the first orifice and the second orifice, with the light guide channel penetrating the buffer layer in the Z-axis direction, and the buffer layer being connected between the negative Z-axis end of the first light-shielding bracket and the positive Z-axis end of the second light-shielding bracket.

[0124] It should be noted that in this embodiment, the docking and communication between the third through hole 101 and the fourth through hole 401 means that a light path can be formed after the docking of the third through hole 101 and the fourth through hole 401, enabling the light emitted by the LED light source 9 to further propagate to the third through hole 101 after reaching the fourth through hole 401. Similarly, the docking and communication between the first through hole and the second through hole, the communication between the first orifice and the second orifice, and the docking and communication between the first light-transmitting hole and the second light-transmitting hole all mean that a light propagation path can be formed.

[0125] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
