Description

Technical Field

[0001] The utility model relates to the field of LED display, in particular to a shell component, an LED display device and an electronic product. Background Art

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

[0003] Some of these electronic products are provided with a translucent display window on an opaque shell, and an LED display module such as a digital tube is provided on the inner side of the shell. Users observe the display pattern on the LED display module through the display window. However, in this type of solution, since the display pattern is formed on the LED display module on the inner side of the shell, the effect of the display pattern viewed by the user from different viewing angles varies greatly, resulting in a poor user experience.

[0004] Other electronic products have a light guide hole in an opaque shell, an LED light source is arranged on the inside of the shell directly opposite the light guide hole, and a light diffusion film covering the light guide hole is attached to the outer surface of the shell. The light emitted by the LED light source is transmitted through the light guide hole to the light diffusion film, and the light diffusion film disperses the light to form a display pattern with relatively uniform lighting brightness on the light diffusion film. This makes it possible for users to observe the display pattern from different viewing angles with less difference, which is conducive to improving user experience.

[0005] However, the light emitted by the LED light source will be dispersed in all directions under the action of the light diffusion film, which makes it easy for the light to be dispersed beyond the boundary / outer contour of the display pattern. On the one hand, this causes light loss, resulting in a reduction in the brightness of the display pattern, and on the other hand, it also causes the outer contour of the display pattern to be blurred, resulting in a decrease in the display effect. Moreover, the stronger the light diffusion film disperses the light, the more uniform the brightness of the display pattern will be, and the greater the light loss that is dispersed beyond the boundary of the display pattern will be, and the blurred the boundary of the display pattern will be. Utility Model Content

[0006] One of the purposes of the present invention is to overcome the above-mentioned defects of the prior art and provide a housing assembly for electronic products.

[0007] The shell component provided by the utility model is used to form a lighted display pattern that can be observed from the outside when a light source is turned on at the inside of the shell component, and the outside surface of the shell component constitutes the outer surface of the electronic product; the shell component includes a light-shielding shell frame, and the light-shielding shell frame has a first light-transmitting hole that penetrates the inside and the outside of the shell component along the thickness direction of the shell component; the first light-transmitting hole is filled with a light-guiding material that is injected and solidified in a fluid state and is used to disperse and propagate light, and the outside surface of the light-guiding material is flush with the hole opening of the first light-transmitting hole located on the outside surface of the light-shielding shell frame; the hole wall at one end of the first light-transmitting hole located on the inside of the light-shielding shell frame is exposed outside the light-guiding material.

[0008] As can be seen from the above, the shell component of the utility model is filled with a light-guiding material injected in a fluid state and solidified in the first light-transmitting hole. In this way, when a light source is turned on inside the shell component, the light-guiding material can transmit the light inside the shell component to the outside of the light-shielding frame, thereby forming a lit display pattern on the shell component. In this way, when the user observes the display pattern at different viewing angles outside the shell component, the observed display effect is less different, which is conducive to improving the user experience.

[0009] Furthermore, since the utility model fills the light-guiding material used to disperse and propagate light into the first light-transmitting hole, it is beneficial to fully and evenly disperse the light within the range limited by the first light-transmitting hole without exceeding the range of the first light-transmitting hole in the direction perpendicular to the thickness. This is beneficial, on the one hand, to concentrate the light generated by the light source to the area where the display pattern is formed, which is beneficial to reduce light loss and improve the brightness of the display pattern. On the other hand, it is also beneficial to make the contour of the display pattern formed thereby clear. On the other hand, it also enables the utility model to specifically set the properties of the light-guiding material (for example, setting the thickness, transmittance and other properties of the light-guiding material) based on the need to disperse the light evenly, thereby better meeting the user's need for evenly dispersed and propagated light, and is beneficial to making the brightness of the display pattern more uniform. The utility model is beneficial to lighting up the outer shell component to form a display pattern with higher brightness, clearer contours and more uniform brightness.

[0010] In addition, since the shell component of the utility model exposes one end of the first light-transmitting hole located on the inner side of the light-shielding shell frame outside the light-guiding material, the shell component of the utility model is able to be well connected with the module that realizes the LED display function at the inner end, thereby minimizing the leakage of light between the shell component and the module that realizes the LED display function (such as the LED display function module described later), which is beneficial to further reduce the loss of light and improve the brightness of the display pattern.

[0011] The inner side and the outer side described in the present invention are all referenced to the inner side and the outer side of the housing component.

[0012] A preferred solution is that the housing assembly further comprises a light-transmissive display surface shell layer, which is attached to the outer surface of the light-shielding frame and covers the opening of the first light-transmissive hole on the outer surface of the light-shielding frame.

[0013] A further solution is that the display surface shell layer is attached to the outer surface of the light-shielding frame by means of in-mold injection molding.

[0014] In-mold injection molding means that during the process of injection molding of the light-shielding shell, the display surface shell layer is placed in the mold cavity of the light-shielding shell in advance, so that the light-shielding shell can be matched and connected with the display surface shell layer during the injection molding process.

[0015] As can be seen from the above, this facilitates forming a thinner display surface shell layer on the outer surface of the light-shielding frame, which is beneficial to reducing the diffusion of light in the display surface shell layer and making the display pattern contour on the surface of the shell component clearer.

[0016] A further solution is that the thickness of the display surface shell layer is 0.1 to 0.2 mm.

[0017] A further solution is that the display surface shell layer is made of a semi-transparent material.

[0018] As can be seen from the above, when the light source inside the outer shell assembly is not turned on, the user cannot easily observe the inner structure through the display surface shell layer. When the light source inside the outer shell assembly is turned on, the light can pass through the display surface shell layer and form a lit display pattern on the display surface shell layer. This is beneficial for forming a lit display pattern on the outer shell assembly and for making the appearance structure of the outer shell assembly more concise.

[0019] A further solution is that the thickness of the display surface shell layer is less than or equal to 1 mm.

[0020] A further solution is that the embedding thickness of the light-guiding material in the first light-transmitting hole is greater than or equal to 2 mm.

[0021] As can be seen from the above, this is conducive to evenly dispersing the light in the light-guiding material.

[0022] A further solution is that the embedding thickness of the light-guiding material in the first light-transmitting hole is less than or equal to 8 mm.

[0023] A further solution is that the outer surface of the light-guiding material filled in the first light-transmitting hole is in contact with the inner surface of the display surface shell layer.

[0024] As can be seen from the above, this makes it easier for the light to be directly transmitted to the display surface shell layer after being emitted from the light guide material, which is further beneficial to reducing the stray light.

[0025] A further solution is that the display surface shell layer constitutes at least a part of the outer shell of the electronic product; or, the light-shielding frame includes a light-shielding shell, and the light-shielding shell constitutes at least a part of the outer shell of the electronic product.

[0026] A further solution is that the outline of the display pattern corresponds to the opening outline of the first light transmission hole.

[0027] The second purpose of the present invention is to provide an LED display device in order to overcome the above-mentioned defects of the prior art.

[0028] The LED display device provided by the utility model comprises an LED display function module and the aforementioned shell component for electronic products, the LED display function module comprises a circuit board and an LED light source fixed on the first main surface of the circuit board, the circuit board is fixed on the inner side of a light-shielding shell frame, and the LED light source faces the first light-transmitting hole along the thickness direction; the first main surface is directly connected to the hole wall of one end of the first light-transmitting hole located on the inner side of the light-shielding shell frame; or the first main surface is connected to the hole wall of one end of the first light-transmitting hole located on the inner side of the light-shielding shell frame through a light-shielding structure, the light-shielding structure has a second light-transmitting hole that penetrates along the thickness direction, and the second light-transmitting hole is connected to the first light-transmitting hole along the thickness direction.

[0029] As can be seen from the above, this makes it easier to transmit the light emitted by the LED light source to the outer shell assembly to form a lit display pattern, and because the hole wall at one end of the first light-transmitting hole located on the inner side of the light-shielding shell frame is exposed outside the light-guiding material, it can be well connected with the LED display function module, which is beneficial to reduce the leakage of light during the transmission process from the LED display function module to the outer shell assembly.

[0030] A preferred solution is that the shading structure includes a buffer layer made of elastic shading material.

[0031] Another preferred solution is that the shading structure includes a shading body, and one end of the shading body close to the shading frame along the thickness direction has a second shading wall arranged around the second light-transmitting hole; the inner wall of the shading frame has a first shading wall arranged around the first light-transmitting hole, and the second shading wall is inserted into the inner periphery and / or outer periphery of the first shading wall along the thickness direction.

[0032] A further solution is that the number of first light-transmitting holes is at least two, the number of second light-transmitting holes is at least two, each first light-transmitting hole corresponds to each second light-transmitting hole one-to-one, and the first light-transmitting hole and the corresponding second light-transmitting hole are connected and communicated with each other along the thickness direction; the first light-transmitting hole and the corresponding second light-transmitting hole are connected to form a light-guiding hole, and adjacent light-guiding holes are separated by corresponding first light-shielding walls and second light-shielding walls; each first light-transmitting hole corresponds to an LED light source.

[0033] Another preferred solution is that the LED display function module and the shell assembly have a positioning structure for positioning the matching position of the LED display function module and the shell assembly perpendicular to the thickness direction; the positioning structure includes a positioning protrusion and a positioning recess, one of the positioning protrusion and the positioning recess is located in the LED display function module, and the other is located in the shell assembly, and the positioning protrusion is inserted into the positioning recess along the thickness direction.

[0034] The third purpose of the utility model is to overcome the above-mentioned defects of the prior art and provide an electronic product.

[0035] The electronic product provided by the utility model comprises the aforementioned LED display device for electronic products, the circuit board is the main control board of the electronic product, or the circuit board is an independent board body electrically connected to the main control board of the electronic product.

[0048] This embodiment of Figures 1 to 9A unified spatial rectangular coordinate system (right-hand system) is used to identify the relative orientation relationship between the various components, wherein the Z-axis direction is the thickness direction of the housing component.

[0049] Please refer to Figures 1 to 9 The electronic product of this embodiment is a massager, the electronic control host of the massager includes the LED display device of this embodiment, and the LED display device of this embodiment includes the housing component 100 and the LED display function module 200 of this embodiment.

[0050] Alternatively, in other embodiments of the present invention, the electronic product may also be a smart skipping rope, an electric toothbrush, a smart speaker, an electronic clock, etc. with an LED display function.

[0051] The shell component 100 for the electronic product of this embodiment is used to form a display pattern such as a lighted "88" that can be observed from the outside when the light source is turned on on the inside. The outer surface of the shell component 100 constitutes the outer surface of the electronic product. The inside and outside of this embodiment are both based on the inside and outside of the shell component.

[0052] The shell assembly 100 includes a light-shielding shell 1, a display surface shell layer 2, a potting fence 3, a first light-shielding frame 4 and a light-guiding material 5 for dispersing and propagating light. The light-shielding shell 1 constitutes the front shell of the electronic product. The light-shielding shell 1 and the rear shell 9 of the electronic product form an installation cavity V100. The LED display function module 200 is fixedly installed in the installation cavity V100. The Z-axis direction shown in the figure is the thickness direction of the light-shielding assembly 100. The negative side of the Z-axis of the shell assembly 100 is the outer side, and the positive side of the Z-axis is the inner side.

[0053] The light shielding housing 1 has a plurality of second light guide holes 11 penetrating through the inner and outer sides thereof along the Z-axis direction. Fourteen of the plurality of second light guide holes 11 are distributed along the extending direction of the strokes of the number "88" (see Figure 3 and Figure 7 , where 7 second light guide holes 11 are distributed along the extending direction of the stroke of one number “8”, and the other 7 second light guide holes 11 are distributed along the extending direction of the stroke of another number “8”).

[0054] The display surface shell layer 2 is made of a light-transmitting material, and the display surface shell layer 2 is fixed to the outer surface (negative side surface of the Z axis) of the light-shielding shell 1 by bonding, covering the opening of the second light guide hole 11 on the outer surface of the light-shielding shell 1 (the opening of the negative end of the second light guide hole 11 on the Z axis), and fits with the outer surface of the light-guiding material 5 filled in the second light guide hole 11. The display surface shell layer 2 can specifically be a light-transmitting sheet structure such as a PET film, a brown lens, or an acrylic sheet. Of course, the display surface shell layer 2 can also be set with reference to other surface films of existing display devices such as digital tubes and electronic clocks in use, and the inner surface of the display surface shell layer 2 fits with the outer surface of the light-shielding shell 1. The thickness of the display surface shell layer 2 is 1 mm, and it is preferred that the display surface shell layer 2 is set to be made of a semi-transmitting material.

[0055] The potting fence 3 is integrally injection molded on the inner surface (Z-axis positive side surface) of the shading shell 1 , and protrudes inward (Z-axis positive side) from the inner surface of the shading shell 1 , and each second light guide hole 11 is located within the surrounding range of the potting fence 3 .

[0056] The first light shielding frame 4 is fixedly installed on the positive side of the Z-axis of the light shielding shell 1 and is located in the area enclosed by the potting fence 3. The first light shielding frame 4 has a plurality of first light guide holes 41 and a plurality of first leakage channels 42 that pass through along the Z-axis direction. Fourteen of the plurality of first light guide holes 41 are distributed along the extension direction of the strokes of the number "88". Each second light guide hole 11 corresponds to each first light guide hole 41 one by one. The second light guide hole 11 is connected to the corresponding first light guide hole 41 along the Z-axis direction. The first leakage channel 42 is staggered with the second light guide hole 11 in the Z-axis direction (similarly, the first leakage channel 42 is also staggered with the third light guide hole 71 described later in the Z-axis direction).

[0057] See also Figures 3 to 8 When producing the housing assembly 100 of the present embodiment, on the basis of the potting fence 3 being integrally formed on the inner surface of the light-shielding housing 1, firstly, a flow-blocking structure F1 is pasted on the outer surface of the light-shielding housing 1, and the opening of the second light-guiding hole 11 on the outer surface of the light-shielding housing 1 is blocked by the flow-blocking structure F1, and the formed combination of the light-shielding housing 1, the potting fence 3 and the flow-blocking structure F1 is placed in a state where the XOY plane is horizontal and the Z axis is vertically upward, so that the potting fence 3, the inner surface of the light-shielding housing 1 and the inner surface of the flow-blocking structure F1 are surrounded to form a potting groove area V1 with the groove opening facing upward, and then a fluid light-guiding material 5 is injected into the potting groove area V1, so that the light-guiding material 5 submerges the second light-guiding hole 11 (see Figure 4 and Figure 5), before the light guide material 5 is cured, the first light shielding frame 4 is installed into the potting groove area V1, so that the negative end of the first light guide hole 41 on the Z axis is sunken into the light guide material 5 and connected to the negative end of the corresponding second light guide hole 11 on the Z axis, and the positive end of the first light guide hole 41 on the Z axis is exposed outside the light guide material 5, and then the light guide material 5 is cured. After the light guide material 5 is cured, the flow blocking structure F1 is removed (see Figure 7 ), and a display surface shell layer 2 is attached to the outer surface of the light shielding shell 1 (see Figure 8 ), the first light shielding frame 4 is fixed in the potting groove area V1 under the action of the cured light guiding material 5.

[0058] The blocking structure F1 of the present embodiment is in the form of a film, and the inner surface of the blocking structure F1 fits with the outer surface of the light-shielding shell 1, so that the outer surface of the cured light-guiding material 5 is flush with the opening of the second light-guiding hole 11 located on the outer surface of the light-shielding shell 1. Preferably, the blocking structure F1 is a flexible film, so that the inner surface of the blocking structure F1 fits well with the outer surface of the light-shielding shell 1, which is beneficial to sealing the opening of the second light-guiding hole 11 located on the outer surface of the light-shielding shell 1. Of course, the specific form of the blocking structure F1 can also be set with reference to the surface film (such as a glued plastic film) in the existing digital tube production process, which will not be repeated here.

[0059] The first light-shielding frame 4 of the present embodiment is fixed in the potting groove area V1 by the cured light-guiding material 5. Optionally, in other embodiments of the present invention, the first light-shielding frame 4 can also be fixedly connected to the light-shielding shell 1 or the potting fence 3 by other existing methods such as snaps, screws, and gluing before the light-guiding material 5 is cured.

[0060] The 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 potting fence and the light-shielding shell can also be set as different parts. The potting fence is fixedly installed on the inner surface of the light-shielding shell and sealed with the inner surface of the light-shielding shell. For example, the potting fence is fixedly installed on the inner surface of the light-shielding shell by gluing. Of course, the 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 closed along a preset closed trajectory (presumably The paste material is extruded along the edge contour trajectory of the potting fence to form the potting fence, and the potting fence can also be removed after the light-guiding material is solidified. Of course, it is preferred to adopt the solution of the present embodiment to integrally injection mold the potting fence 3 on the inner surface of the light-shielding shell 1. This not only helps to save the installation process of the potting fence 3 and simplify the production process of the outer shell assembly 100, but also helps to ensure that the potting fence 3 and the light-shielding shell 1 do not leave a fitting gap, and the fluid light-guiding material 5 will not leak out from between the potting fence and the light-shielding shell after being injected into the potting groove area V1, which is beneficial to improving the yield rate of the outer shell assembly.

[0061] In the present embodiment, during the production process of the shell component 100, a flow-blocking structure F1 is used to block the opening of the second light-guiding hole 11 on the outer surface of the light-shielding shell 1, and the flow-blocking structure F1 is removed after the light-guiding material 5 is cured. Thereafter, the display surface shell layer 2 is re-attached to the outer surface of the light-shielding shell 1, so that when a light source (such as the LED light source 8 described later) is turned on the inner side of the shell component 100, a lighted display pattern is formed on the display surface shell layer 2 (at this time, the outer surface of the display surface shell layer 2 constitutes the outer surface of the shell component 100), and the contour of the display pattern corresponds to the contour of the opening of the negative end of the Z-axis of the second light-guiding hole 11. Optionally, in other embodiments of the present invention, the display surface shell layer can also be used as a flow-blocking structure, that is, before the light-guiding material is injected into the potting groove area. Before the light shielding shell is formed, the display surface shell layer is attached to the outer surface of the light shielding shell, and the opening of the second light guide hole on the outer surface of the light shielding shell is blocked by the display surface shell layer, and the display surface shell layer is still retained on the outer surface of the light shielding shell after the light guide material is solidified; alternatively, the display surface shell layer can 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 shell, so that when there is an turned-on LED light source 8 on the inner side of the shell assembly, the illuminated display pattern is directly formed on the outer surface of the light shielding shell by the light guide material. Of course, in the shell assembly produced in this way, the outer surface of the light shielding shell constitutes the outer surface of the shell assembly, and the outline of the display pattern is the outline of the opening of the negative end of the second light guide hole 11 on the Z axis, and the shell assembly no longer has a display surface shell layer.

[0062] The display surface shell layer is used as a flow-blocking structure, so that the light-guiding material is in contact with the inner surface of the display surface shell layer when it is in a fluid state. This is beneficial to ensure that the light-guiding material and the display surface shell layer are well fitted at all locations, and is beneficial for allowing light to pass directly into the display surface shell layer after being transmitted from the light-guiding material, thereby reducing the loss of light in the process of propagating from the light-guiding material to the display surface shell layer, and is beneficial to improving the display effect.

[0063] Furthermore, in the embodiment where the display surface shell layer is used as a flow-blocking structure, in addition to attaching the display surface shell layer to the outer surface of the light-shielding shell by conventional means such as pasting, the display surface shell layer can also be attached to the outer surface of the light-shielding shell (the negative side surface of the light-shielding shell on the Z axis) by in-mold injection molding, and the display surface shell layer covers the negative end opening of the second light guide hole on the Z axis, and blocks the negative end opening of the second light guide hole on the Z axis. The in-mold injection molding method is conducive to making the display surface shell layer and the outer surface of the light-shielding shell fit more closely, thereby enabling the display surface shell layer to be used as a flow-blocking structure to block the opening of the second light guide hole. In addition, the in-mold injection molding method can form a display surface shell layer with a thinner thickness. For example, the thickness of the display surface shell layer can be set to 0.1 mm. Thinner thicknesses such as 0.125 mm, 0.175 mm, 0.188 mm, and 0.2 mm are beneficial to reducing the stray light in the display surface shell layer, and are beneficial to making the outline of the displayed pattern clearer; of course, since this embodiment uses the display surface shell layer used as the flow-blocking structure to be attached to the outer surface of the light-shielding shell by in-mold injection molding, and since the potting fence of this embodiment can also be integrally injection molded with the light-shielding shell, the combination of the light-shielding shell, the potting fence and the flow-blocking structure can also be formed in the production stage of the light-shielding shell, without the need to assemble the light-shielding shell, the potting fence and the flow-blocking structure after their respective production is completed to form a combination of the light-shielding shell, the potting fence and the flow-blocking structure, which is beneficial to simplifying the production procedures and production process of the outer shell components.

[0064] Optionally, in other embodiments of the present invention, a potting fence is fixed on the inner surface of the light-shielding shell, a flow-blocking structure is attached to the outer surface of the light-shielding shell, and the light-shielding shell is placed in a state with the inner side facing up and the outer side facing down. The order of these three operations can be adjusted as needed.

[0065] In the process of installing the first light shielding frame 4 into the potting groove area V1 in this embodiment, the light guiding material 5 in the potting groove area V1 enters the first light guiding hole 41 and the first leakage channel 42 from the negative end of the Z axis from bottom to top under the squeezing action of the first light shielding frame 4. The provision of the first leakage channel 42 is helpful to accelerate the release of the pressure on the light guiding material 5, reduce the resistance of the light guiding material 5 to the installation of the first light shielding frame 4 into the potting groove area V1, and reduce the difficulty of installing the first light shielding frame 4 into the potting groove area V1.

[0066] Optionally, in other embodiments of the present invention, a second leakage channel (not shown in the figure) can also be provided, the second leakage channel is formed between the first light shielding frame and the inner peripheral wall surface of the potting fence, the second leakage channel also connects the two sides of the first light shielding frame along the Z-axis direction, the second leakage channel and the second light guide hole are staggered in the Z-axis direction (similarly, the second leakage channel and the third light guide hole 71 described later are staggered in the Z-axis direction), so that in the process of the first light shielding frame being installed into the potting groove area, the light-guiding material can also enter the second leakage channel, which is further beneficial to reduce the resistance of the light-guiding material to the installation of the first light shielding frame into the potting groove area, and reduce the difficulty of installing the first light shielding frame into the potting groove area; of course, the first leakage channel and the second leakage channel can also be cancelled, so that in the process of installing the first light shielding frame into the potting groove area, the light-guiding material is only discharged into the first light guide hole in the positive direction of the Z-axis.

[0067] As for the specific positions of the first leakage channel and the second leakage channel, they can be reasonably arranged according to the distribution of the second light guide holes and the need to uniformly accommodate the light guide material, which will not be elaborated here.

[0068] Preferably, the first light-shielding frame 4 and the light-shielding shell 1 cooperate with each other to have a first positioning structure. The first positioning structure of the present embodiment is the inner peripheral wall surface of the potting fence 3 and the outer peripheral wall surface of the first light-shielding frame 4. The light-shielding shell 1 and the first light-shielding frame 4 are positioned in a cooperation position perpendicular to the Z-axis direction by the contact cooperation between the inner peripheral wall surface of the potting fence 3 and the outer peripheral wall surface of the first light-shielding frame 4. Optionally, in other embodiments of the present utility model, the first positioning structure includes a first positioning protrusion integrally formed on the light-shielding shell and a first positioning recess integrally formed on the first light-shielding frame. The first positioning protrusion is a columnar structure extending from the inner side surface of the light-shielding shell in the positive direction of the Z-axis, and the first positioning recess is a hole-shaped structure extending along the Z-axis direction. The first positioning protrusion is inserted into the first positioning recess along the positive direction of the Z-axis. Of course, by the same token, the first positioning protrusion can also be arranged on the first light-shielding frame, and the first positioning recess can be arranged on the light-shielding shell.

[0069] The light-shielding housing 1 of the present embodiment is provided with a first slot 12 which is recessed in the negative direction of the Z-axis on the inner surface (the positive side surface of the Z-axis). The extension trajectory of the first slot 12 on the inner surface of the light-shielding housing 1 surrounds the positive end openings of the aforementioned second light-guiding holes 11 in the Z-axis respectively (that is, each second light-guiding hole 11 is respectively located in a different encirclement formed by the first slot 12). The negative end of the Z-axis of the first light-shielding frame 4 is provided with a first insertion protrusion 43 which protrudes in the negative direction of the Z-axis. The extension trajectory of the first insertion protrusion 43 matches the extension trajectory of the first slot 12. The extension trajectory of the first insertion protrusion 43 surrounds the negative end openings of the Z-axis of each first light-guiding hole 41 respectively. The first insertion protrusion 43 is inserted into the first slot 12 along the negative direction of the Z-axis. The cooperation between each group of second light-guiding holes 11 and the first light-guiding holes 41 is separated by the cooperation between the first insertion protrusion 43 and the first slot 12. In the present embodiment, the groove wall of the first slot 12 and the first insertion protrusion 43 both constitute a light-shielding housing. The first convex portion 43 and the first slot 12 are provided to reduce the leakage of light between the light-shielding shell 1 and the first light-shielding frame 4. Optionally, in other embodiments of the present invention, the first convex portion 43 can be formed on the inner surface of the light-shielding shell, and the first slot can be formed on the negative end of the Z-axis of the first light-shielding frame. The concave-convex structure provided on the first light-shielding frame around the negative end of the Z-axis of the first light-guiding hole constitutes a part of the hole wall of the negative end of the Z-axis of the first light-guiding hole. The concave-convex structure formed on the inner surface of the light-shielding shell constitutes a part of the inner surface of the light-shielding shell. The docking of the two concave-convex structures also constitutes the docking of the hole wall of the negative end of the Z-axis of the first light-guiding hole with the inner surface of the light-shielding shell. Of course, the first convex portion and the first slot can also be eliminated, so that the hole wall of the positive end of the Z-axis of the second light-guiding hole is docked with the hole wall of the negative end of the Z-axis of the first light-guiding hole in an end-face contact manner. In this way, the structures of the light-shielding shell and the first light-shielding frame are simpler.

[0070] Please refer to Figure 2 and Fig. 9 The LED display function module 200 of this embodiment includes a circuit board 6, a second light shielding frame 7 (an example of a light shielding body) and a plurality of LED light sources 8. The normal line of the main surface of the circuit board 6 is along the Z-axis direction. The LED light source 8 and the second light shielding frame 7 are both fixedly arranged on the main surface on the negative side of the Z-axis of the circuit board 6 (an example of the first main surface). Fourteen of the plurality of LED light sources 8 are distributed along the extension direction of the stroke of the number "88". The second light shielding frame 7 has a plurality of third light guide holes 71 that penetrate along the Z-axis direction. Fourteen of the plurality of third light guide holes 71 are distributed along the extension direction of the stroke of the number "88".

[0071] The hole wall of the third light guide hole 71 at the positive end in the Z axis is connected to the main surface of the circuit board 6 on the negative side in the Z axis, and each LED light source 8 corresponds to each third light guide hole 71 one by one. The LED light source 8 is located in the hole cavity of the corresponding third light guide hole 71 at the positive end in the Z axis; preferably, the hole wall of the third light guide hole 71 at the positive end in the Z axis is tightly matched with the main surface of the circuit board 6 on the negative side in the Z axis to minimize light leakage.

[0072] The LED display function module 200 is fixed on the inner side (positive side of the Z axis) of the outer shell assembly 100, the positive end of the Z axis of the first light shielding frame 4 is connected to the negative end of the Z axis of the second light shielding frame 7, each third light guide hole 71 corresponds to each first light guide hole 41 one by one, and the negative end of the Z axis of the third light guide hole 71 is connected to the positive end of the Z axis of the corresponding first light guide hole 41.

[0073] Specifically, the first light shielding frame 4 is formed with a second slot 44 recessed toward the negative direction of the Z axis at the positive end of the Z axis, and the second slot 44 surrounds the positive end openings of each first light guide hole 41 in the Z axis respectively. The negative end of the second light shielding frame 7 is formed with a second insertion protrusion 72 protruding toward the negative direction of the Z axis, and the extension trajectory of the second insertion protrusion 72 matches the extension trajectory of the second slot 44. The extension trajectory of the second insertion protrusion 72 surrounds the negative end openings of each third light guide hole 71 in the Z axis respectively, and the second insertion protrusion 72 is inserted into the second slot 44 along the negative direction of the Z axis. The cooperation between each group of first light guide holes 41 and the third light guide holes 71 is separated by the cooperation between the second insertion protrusion 72 and the second slot 44. In this embodiment, The groove wall of the second slot 44 constitutes a first light-shielding wall 45, and the second insertion protrusion 72 constitutes a second light-shielding wall. The positive end of each first light guide hole 41 in the Z-axis direction is surrounded by the first light-shielding wall 45, and the first light-shielding wall 45 surrounds the positive end opening of each first light guide hole 41 in the Z-axis direction respectively. The negative end of each third light guide hole 71 in the Z-axis direction is surrounded by a second light-shielding wall. The second light-shielding wall surrounding the third light guide hole 71 is matched with the first light-shielding wall 45 surrounding the corresponding first light guide hole 41. The second light-shielding wall is matched with the outer periphery of the corresponding first light-shielding wall 45. The matching between each group of first light guide holes 41 and third light guide holes 71 is blocked by the matching between the corresponding first light-shielding wall 45 and the second light-shielding wall.

[0074] In this way, the circuit board 6, the second light shielding frame 7, the first light shielding frame 4, the light shielding shell 1, and the display surface shell layer 2 are connected in sequence along the negative direction of the Z axis, and between the circuit board 6 and the display surface shell layer 2, the third light guide hole 71, the corresponding first light guide hole 41 and the corresponding second light guide hole 11 are connected and connected in sequence along the positive direction of the Z axis to form a light guide channel. The light emitted by the LED light source 8 is transmitted to the display surface shell layer 2 through the corresponding third light guide hole 71, the corresponding first light guide hole 41 and the corresponding second light guide hole 11 in sequence, thereby forming a lit display pattern on the display surface shell layer 2. When the aforementioned 14 LED light sources 8 are all turned on, the light of each LED light source 8 is transmitted to the display surface shell layer 2 through the corresponding combination of the third light guide hole 71, the first light guide hole 41 and the second light guide hole 11, thereby forming a lit "88" (display pattern) on the display surface shell layer 2.

[0075] In this embodiment, the sum of the encapsulation thickness dimensions of the light-guiding material 5 in the second light-guiding hole 1 and the first light-guiding hole 41 is 8 mm; optionally, in other embodiments of the present invention, the sum of the encapsulation thickness dimensions of the light-guiding material 5 in the second light-guiding hole 1 and the first light-guiding hole 42 may also be set to 3 mm, 5 mm, or other dimensions greater than or equal to 2 mm.

[0076] In this embodiment, since the light guiding material 5 is poured into the second light guiding hole 11, the light guiding material 5 can be used to evenly disperse the light emitted by the LED light source 8 to the display surface shell layer 2, so that the display pattern is directly formed on the shell component. When the user observes the display pattern outside the shell component, it is beneficial to reduce the difference in display effects under different observation angles, which is beneficial to improving the user experience.

[0077] Furthermore, since the light-guiding material 5 used to disperse and propagate light in the present embodiment is filled in the first light-guiding hole 41 and the second light-guiding hole 11, it is beneficial to fully and evenly disperse the light within the range defined by the first light-guiding hole 41 and the second light-guiding hole 11, and will not exceed the range of the first light-guiding hole 41 and the second light-guiding hole 11 in the direction perpendicular to the Z-axis. This is beneficial, on the one hand, to concentrate the light generated by the LED light source 8 to the area where the display pattern is formed, which is beneficial to reduce light loss and improve the brightness of the display pattern. On the other hand, it is also beneficial to make the contour of the display pattern formed thereby clear. On the other hand, this also enables the present embodiment to specifically set the properties of the light-guiding material 5 (for example, setting the thickness, size, transmittance and other properties of the light-guiding material 5) based on the need to disperse the light evenly, thereby better meeting the user's need for evenly dispersed and propagated light, and is beneficial to making the brightness of the display pattern more uniform. The present embodiment is beneficial to lighting up the outer shell component 100 to form a display pattern with higher brightness, clearer contours, and more uniform brightness.

[0078] Furthermore, since the present embodiment does not need to rely on the display surface shell layer 2 to evenly disperse and propagate the light, 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 evenly disperse the light. 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, thereby making the display pattern contour on the surface of the display surface shell layer 2 clearer.

[0079] In addition, since the shell component 100 of the present embodiment exposes the positive end of the Z-axis of the first light guide hole 41 outside the light guide material 5, this makes it possible for the shell component 100 of the present embodiment to be well connected with the LED display function module 200 through the positive end of the Z-axis of the first light shielding frame 4, thereby minimizing the leakage of light between the LED display function module 200 and the shell component 100, which is further beneficial to reduce the loss of light and further beneficial to make the display pattern lit on the shell component 100 more uniform in brightness and clearer in outline.

[0080] In addition, since the present embodiment forms a potting groove area V1 during the production of the housing component 100, and first injects a fluid light-guiding material 5 into the potting groove area V1, and then installs the first light-shielding frame 4 into the potting groove area V1 before the light-guiding material 5 is solidified, compared with the technical solution that requires injecting light-guiding material into each second light-guiding hole separately, since the size of the potting groove area V1 of the present embodiment is often larger than the size of a single second light-guiding hole 11 of the first light-shielding frame 4 therein, the present embodiment has lower requirements on the process accuracy of injecting the light-guiding material 5 into the potting groove area V1, and the difficulty of the potting process of the light-guiding material 5 is lower. In addition, regardless of how many second light-guiding holes the present embodiment has, For the combination of the second light guide holes 11 and the first light guide holes 41, the light guide material 5 only needs to be poured once, so that each second light guide hole 11 can be filled with the light guide material 5, and after the first light shielding frame 4 is installed in the pouring groove area V1, the negative end of the Z-axis of each first light guide hole 41 can be filled with the light guide material 5. In this embodiment, there is no need to adjust the injection process of the light guide material 5 according to the number of combinations of the second light guide holes 11 and the first light guide holes 41, and there is no need to perform multiple pouring when the number of combinations of the second light guide holes 11 and the first light guide holes 41 is large, which is beneficial to improving the stability of the pouring process, and is beneficial to improving the injection efficiency of the light guide material 5, and is beneficial to simplifying the production process of the shell component 100.

[0081] Specifically, the LED light source 8 of the present embodiment is an LED lamp bead. Optionally, in other embodiments of the utility model, the LED light source 8 may also be a separate LED chip. The LED chip may be mounted on the metal electrode of the circuit board 6 in a face-up or face-down manner. For example, the LED chip is connected to the metal electrode on the circuit board 6 through a metal wire when face-up. The specific installation method of the LED chip on the circuit board 6 may refer to the prior art and will not be repeated here.

[0082] Preferably, the cooperation between the LED display function module 200 and the shell assembly 100 has a second positioning structure (not shown in the figure), and the second positioning structure is used to position the cooperation position of the LED display function module 200 and the shell assembly 100 in a direction perpendicular to the Z-axis. Specifically, the second positioning structure includes a second positioning protrusion and a second positioning recess. One of the second positioning protrusion and the second positioning recess is located in the LED display function module 200, and the other is located in the shell assembly 100. The second positioning protrusion is inserted into the second positioning recess along the Z-axis direction. For example, the second positioning protrusion is located in the light-shielding shell 1, and the second positioning recess is opened in the circuit board 6. The specific scheme of the cooperation between the second positioning protrusion and the second positioning recess can be set with reference to the cooperation between the first positioning protrusion and the first positioning recess, which will not be repeated here.

[0083] The second positioning structure, the second positioning protrusion and the second positioning recess of the present embodiment are examples of the positioning structure, the positioning protrusion and the positioning recess respectively.

[0084] Optionally, in other embodiments of the LED display device of the present invention, a colloidal light-shielding filler is adhered to the first light-shielding wall 45, and the light-shielding filler is filled between the first light-shielding wall 45 and the second light-shielding wall. For example, the light-shielding filler is black latex. Before the operator mates and installs the LED display function module 200 with the shell assembly 100, the operator first immerses the second light-shielding wall in liquid black latex to make the liquid black latex adhere to the second light-shielding wall, and then inserts and fits the first light-shielding wall 45 with the second light-shielding wall, and the black latex is filled between the first light-shielding wall 45 and the second light-shielding wall. The provision of the light-shielding filler is beneficial to further reduce the leakage of light between the LED display function module 200 and the shell assembly 100, and the liquid black latex, as a kind of adhesive, can also seal the first light-shielding wall after curing. The light wall 45 is fixedly connected to the second light-shielding wall, which is beneficial to improving the matching stability of the first light-shielding wall 45 and the second light-shielding wall; of course, the light-shielding filler can be in a colloidal state or in a particulate state, for example, the light-shielding filler is rubber particles, and the light-shielding filler can be first adhered to the first light-shielding wall 45, or the light-shielding filler can be adhered to both the first light-shielding wall 45 and the second light-shielding wall, and then the first light-shielding wall 45 and the second light-shielding wall are matched with each other through the sleeve, so that the light-shielding filler is filled between the first light-shielding wall 45 and the second light-shielding wall. Of course, the filling of the space between the first light-shielding wall 45 and the second light-shielding wall by the light-shielding filler can be partial filling or full filling. As long as the space between the first light-shielding wall 45 and the second light-shielding wall is filled with light-shielding filler, it is beneficial to reduce the leakage and stray light between the first light-shielding wall 45 and the second light-shielding wall.

[0085] The LED display function module 200 in this embodiment only uses the second light shielding frame 7 as a light shielding structure, and the main surface of the negative side of the Z axis of the circuit board 6 is connected to the hole wall of the positive end of the Z axis of the first light guide hole 41 through the second light shielding frame 7. By inserting and matching the second light shielding wall of the negative end of the Z axis of the second light shielding frame 7 with the first light shielding wall 45 of the positive end of the Z axis of the first light shielding frame 4, it is not only helpful to reduce the leakage of light between the LED display function module 200 and the housing component 100, so that the light will have less leakage and stray phenomena as much as possible during the process of propagating from the LED light source 8 to the second light guide hole 11, but also to reduce the leakage of light between the LED display function module 200 and the housing component 100. The present embodiment can adjust the relative matching position of the LED display function module 200 and the housing assembly 100 by adjusting the depth of the second light shielding wall and the first light shielding wall 45, so that the relative matching position of the LED display function module 200 and the housing assembly 100 is more flexible, which is conducive to reducing the difficulty of matching and installing the LED display function module 200 and the housing assembly 100. Optionally, in other embodiments of the present utility model, the buffer layer made of elastic light shielding material can also be used as a light shielding structure, and the third light guide hole 71 is set to pass through the entire light shielding structure along the Z-axis direction, for example Fig.10 The LED display device shown in the figure sets the shading structure to be composed of only the buffer layer 10a, that is, the second shading frame 7 of the present embodiment is eliminated, and the main surface on the negative side of the Za axis of the circuit board 6a, the buffer layer 10a, and the positive end of the Za axis of the first shading frame 4a are connected in sequence. Fig.10 The Xa-axis direction, Ya-axis direction and Za-axis direction of the illustrated scheme correspond to the X-axis direction, Y-axis direction and Z-axis direction of the present embodiment respectively; for another example, the shading structure is configured to be composed of a buffer layer and a second shading frame. In this case, the buffer layer may be connected between the main surface of the negative Z-axis side of the circuit board and the positive Z-axis end of the second shading frame, or between the negative Z-axis end of the second shading frame and the positive Z-axis end of the first shading frame, or between the negative Z-axis end of the second shading frame and the positive Z-axis end of the first shading frame, or between the main surface of the negative Z-axis side of the circuit board and the positive Z-axis end of the second shading frame, and between the negative Z-axis end of the second shading frame and the positive Z-axis end of the first shading frame. The provision of the buffer layer is also beneficial to reduce the leakage of light between the LED display function module and the outer shell assembly, and is beneficial to making the relative matching position of the LED display function module and the outer shell assembly more flexible. Specifically, the buffer layer may be, for example, a sponge pad, a silicone pad, etc. Of course, in other embodiments of the utility model, please refer to Fig.11 , the shading structure can also be cancelled, in which case the main surface of the negative Zb axis side of the circuit board 6b is directly connected to the positive Zb axis end of the first shading frame 4b. Fig.11 The Xb-axis direction, the Yb-axis direction and the Zb-axis direction of the illustrated scheme correspond to the X-axis direction, the Y-axis direction and the Z-axis direction of the present embodiment, respectively.

[0086] Please refer to Figure 2 and Fig. 9In the electronic product of this embodiment, specifically, the circuit board 6 is the main control board of the electronic product of this embodiment. Optionally, in other embodiments of the present utility model, the circuit board may also be an independent board electrically connected to the main control board of the electronic product.

[0087] The LED display function module 200 is fixedly installed in the installation cavity V100 by screws, the front shell has a first positioning installation column 14 cantilevered from the installation cavity V100 along the positive direction of the Z axis, the rear shell 9 has a second positioning installation column (not shown in the figure) cantilevered toward the installation cavity V100 along the negative direction of the Z axis, the circuit board 6 is squeezed between the first positioning installation column 14 and the second positioning installation column, and the screw (not shown in the figure) penetrates the second positioning installation column and the circuit board 6 in sequence from the positive side of the Z axis of the rear shell 9 along the negative direction of the Z axis, and then cooperates with the first positioning installation column 14 by thread, thereby realizing the fixed connection between the rear shell 9, the LED display function module 200 and the front shell; optionally, in other embodiments of the utility model, the front shell, the rear shell 9 and the LED display function module 200 can also be installed by other existing methods such as snap-fitting, gluing, etc. For example, the LED display function module 200 is first fixed to the front shell by screws, and then the front shell and the rear shell 9 are fixedly connected by snap-fitting.

[0088] It should be noted that, in this embodiment, the second light guide hole 11 is connected to the first light guide hole 41, which means that the second light guide hole 11 and the first light guide hole 41 can form a light path after being connected, so that the light emitted by the LED light source 8 can further propagate to the second light guide hole 11 after propagating to the first light guide hole 41. Similarly, the first light guide hole 41 and the third light guide hole 71 are connected to each other, which means that the first light guide hole 41 and the third light guide hole 71 can form a light path after being connected, so that the light emitted by the LED light source 8 can further propagate to the first light guide hole 41 after propagating to the third light guide hole 71.

[0089] In the present embodiment, the display surface shell layer 2 is configured as a semi-transparent layer. In this way, when the LED light source 8 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 8 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 display pattern on the outer shell component 100 when the LED light source 8 is turned on, and for making the appearance structure of the outer shell component more concise when the LED light source 8 is turned off. Of course, in other embodiments of the present invention, the transmittance of the display surface shell layer 2 can also be adjusted 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 8 is normally turned off.

[0090] The combination of the light-shielding shell 1 and the first light-shielding frame 4 of the present embodiment constitutes a light-shielding shell frame, the combination of the second light-guiding hole 11 and the corresponding first light-guiding hole 41 constitutes a first light-transmitting hole, and the third light-guiding hole 71 constitutes a second light-transmitting hole of the light-shielding structure. Optionally, in other embodiments of the present invention, the light-shielding shell frame can also be provided as a single integrally formed part (for example, the light-shielding shell frame can be integrally formed into a structure having the same structure as the combination of the light-shielding shell 1 and the first light-shielding frame 4 of the present embodiment). Of course, in this way, during the production process of the outer shell assembly, it is necessary to inject fluid-like light-guiding material into each first light-transmitting hole respectively, without providing a potting fence, a first leakage channel and a second leakage channel.

[0091] In this embodiment, the front shell of the electronic product (a part of the outer shell of the electronic product) is set as the light shielding shell 1, and the light shielding shell 1 is used as a part of the light shielding frame. The potting groove area V1 is formed on the light shielding shell 1. Fig.12 In other embodiments of the present utility model, the front shell of the electronic product can also be set as a light-transmitting shell 1c, and the light-transmitting shell 1c is used as a display surface shell layer, and the potting groove area V1c is formed on the light-transmitting shell 1c, and the second light guide hole 11 of this embodiment is cancelled, and the hole wall of the negative end of the Zc axis of the first light guide hole 41c is connected to the inner surface of the light-transmitting shell 1c. The light emitted by the light source turned on inside the shell component is transmitted through the first light guide hole 41c to the light-transmitting shell 1c to form a display pattern that the user can observe on the outside of the shell component. The contour of the display pattern corresponds to the contour of the hole opening of the negative end of the Zc axis of the first light guide hole 41c. In this way, there is no risk of leakage of the fluid light-guiding material 5c through the second light guide hole, which is beneficial to improving the production yield and quality of the shell component. In addition, there is no need to set an additional flow-blocking structure, which is beneficial to simplifying the production process of the shell component and reducing the difficulty of producing the shell component. Fig.12The Xc-axis direction, Yc-axis direction and Zc-axis direction of the scheme shown correspond to the X-axis direction, Y-axis direction and Z-axis direction of the present embodiment, respectively; preferably, the light-transmissive shell 1c is a semi-transmissive shell, so that on the one hand, when the LED light source is turned on inside the shell component, a lighted display pattern can be formed on the semi-transmissive shell, and on the other hand, when the LED light source is not turned on inside the shell component, the inner structure can be shielded and hidden by the semi-transmissive shell, so that it is not easy for the user to observe the inner structure (such as the first light-shielding frame inside) through the semi-transmissive shell, which is conducive to making the appearance structure of the shell component simple, and then to making the appearance structure of the corresponding electronic product simple; in the embodiment in which the front shell is set as a light-transmissive shell, the first light-shielding frame alone constitutes the light-shielding shell frame of the present utility model, and the first light guide hole alone constitutes the first light-transmissive hole of the present embodiment; and, in other embodiments in which the front shell of the electronic product is set as a light-transmissive shell and the light-transmissive shell is used as a display surface shell layer, the potting groove area can also be cancelled. Of course, the light-guiding material filled in each first light guide hole needs to be injected one by one.

[0092] Specifically, the semi-transparent shell can be integrally injection-molded from a semi-transparent material, or can be formed by combining a translucent shell with a semi-transparent film attached to its outer surface, and the semi-transparent film can be obtained by silk-screen printing, spraying, in-mold injection molding, etc.

[0093] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
