Description

Technical Field

[0001] This utility model relates to the field of panels, and in particular to a light-transmitting panel structure. Background Technology

[0002] Panel structures are commonly used in electrical products, such as toys and home appliances. These panels typically display text and graphics. However, traditional panel structures generally lack the ability to transmit light to display text and graphics, or the light is not concentrated enough, resulting in unclear display and affecting the user experience. Therefore, improvements are needed to address this shortcoming of traditional panel structures. Utility Model Content

[0003] Therefore, it is necessary to provide a light-transmitting panel structure to address the problems of traditional panel structures not having the function of displaying text and patterns through light transmission or the insufficient concentration of light resulting in unclear display of text and patterns.

[0004] A light-transmitting panel structure includes: a PCB board assembly; a lamp body assembly disposed on the PCB board assembly; a light-shielding assembly disposed on the PCB board assembly, the light-shielding assembly surrounding the lamp body assembly, the light-shielding assembly having a light transmission channel, and an opening at one end of the light-shielding assembly away from the PCB board assembly, the opening communicating with the light transmission channel; and a panel assembly disposed on the light-shielding assembly, the panel assembly closing the opening, the panel assembly having a cutout area, the cutout area being in the shape of text or a pattern, and the portion of the panel assembly with the cutout area being made of a light-transmitting material.

[0005] This application discloses a light-transmitting panel structure. The panel assembly has sections made of light-transmitting material in the form of text or patterns, allowing light emitted from the lamp assembly to pass through and display the text. This design has multiple functions, such as improving user visibility in low-light conditions and serving a decorative purpose. A light-shielding component surrounds the lamp assembly and has a light transmission channel, directing the light emitted from the lamp assembly to a specific area of ​​the panel assembly. This design prevents light scattering in all directions, ensuring clear and bright display of the light-transmitting text or patterns. The panel assembly can use light-transmitting material only in the areas with cut-out text or patterns, creating a strong contrast between the displayed content and the background. Alternatively, the entire panel assembly can be made of light-transmitting material, with the cut-out areas distinguished by other colors.

[0006] In one embodiment, a light-transmitting plate is also included. This light-transmitting plate is disposed on the light-shielding component and located within the light transmission channel, between the lamp body component and the panel component. Because the light-transmitting plate is positioned between the lamp body component and the panel component, light emitted from the lamp body component can be directly transmitted to the panel component after passing through the light-transmitting plate, thereby displaying text or patterns on the panel component. The light-transmitting plate enhances the overall strength of the product. The light-transmitting plate is made of a light-transmitting material, while the light-shielding component is made of an opaque material. This design allows for the injection molding of the light-transmitting plate using a light-transmitting material in the first mold, and then the injection molding of the light-shielding component using an opaque material in the second mold. This method allows for the production of both the light-transmitting plate and the light-shielding component through two injection molding processes. Light-transmitting materials can be used in areas where light transmission is needed, and opaque materials can be used in areas where light transmission is not needed, making the manufacturing process simpler and more convenient.

[0007] In one embodiment, the light-shielding component has an adapter groove located on its inner side, and the light-transmitting plate mates with the adapter groove. This mating of the light-transmitting plate and the adapter groove improves the overall assembly's rigidity, preventing loosening or displacement during use. Furthermore, the adapter groove can be formed during injection molding; for example, the side of the light-transmitting plate can be embedded into the adapter groove and injection molded tightly, making manufacturing simple and convenient, simplifying the assembly process, and improving production efficiency.

[0008] In one embodiment, the adapter groove is arranged around the inner side of the light-shielding component. By arranging the adapter groove around the inner side, the light-transmitting panel receives uniform support and restraint at all circumferential positions, avoiding assembly deviations or loosening caused by uneven local stress. This design makes the connection between the light-transmitting panel and the light-shielding component tighter, improving the overall mechanical strength and impact resistance of the structure. The surrounding groove can be formed in one step using a mold; after the light-transmitting panel is embedded, it can be directly injection molded and covered without additional processing steps, further simplifying the production process and improving the yield rate.

[0009] In one embodiment, the light-transmitting plate is provided with multiple positioning holes, all located on the same side of the light-transmitting plate. By having multiple positioning holes on the same side of the light-transmitting plate, the positional accuracy of the light-transmitting plate in the second mold is ensured, preventing injection molding misalignment. This design eliminates the need for additional positioning structures; precise positioning can be achieved using existing openings in the light-transmitting plate, reducing mold complexity and production costs. Furthermore, positioning is simple and convenient, improving production efficiency.

[0010] In one embodiment, there are multiple lamp components, all of which are disposed on the PCB board assembly and located within the light transmission channel. All lamp components are positioned on the side of the PCB board assembly facing the panel assembly. By having multiple lamp components within the light transmission channel, more light is transmitted to the panel assembly, ensuring that the display brightness of the translucent text or patterns meets the visibility requirements under different ambient light conditions. The integration of multiple lamp components on the same PCB board assembly eliminates the need for additional wiring or support structures, saving space and facilitating assembly and maintenance.

[0011] In one embodiment, the light-shielding component is snapped into the PCB board assembly. This snap-fit ​​design allows for rapid positioning and fixation of the light-shielding component and the PCB board assembly, simplifying the assembly process and improving production efficiency. This design ensures a tight fit between the light-shielding component and the PCB board assembly, preventing loosening or displacement due to vibration or external forces during use.

[0012] In one embodiment, the PCB assembly has mating holes that engage with the PCB assembly. The engagement of the mating holes with the light-shielding component forms a mechanical alignment reference, ensuring accurate installation of the light-shielding component and the PCB assembly, thus improving assembly precision. This design achieves a secure connection between the light-shielding component and the PCB assembly, preventing loosening due to vibration or external forces during use.

[0013] In one embodiment, the light-shielding assembly includes a light-shielding part, a mating part, and a limiting part. The light-shielding part is disposed on the panel assembly and surrounds the lamp body assembly. The light-shielding part has the opening. The mating part is disposed on the light-shielding part and mates with the mating hole. The limiting part is disposed on the mating part and is located at the end of the mating part away from the light-shielding part. By surrounding the lamp body assembly with the light-shielding part, light divergence can be reduced, making light transmission more concentrated. By mating with the mating hole, the stability and reliability of the assembly between the light-shielding assembly and the PCB board assembly can be improved. By positioning the limiting part at the end of the mating part away from the light-shielding part, the light-shielding assembly can be prevented from detaching from the PCB board assembly, further improving the assembly's robustness.

[0014] In one embodiment, the light-shielding part abuts against one side of the PCB board assembly, and the limiting part abuts against the other side of the PCB board assembly. By having the light-shielding part abut against one side of the PCB board assembly and the limiting part abut against the other side, bidirectional positioning of the PCB board assembly is achieved, ensuring that the light-shielding component is accurately and stably positioned on the PCB board assembly. This design effectively prevents axial displacement of the PCB board assembly due to vibration or external forces during use.

[0015] In one embodiment, the limiting portion is located on the outside of the PCB board assembly. By positioning the limiting portion on the outside of the PCB board assembly, the limiting portion abuts against the PCB board assembly, thereby effectively restricting the degree of freedom of the PCB board assembly, effectively preventing the light-shielding component from disengaging from the PCB board assembly in the axial direction, ensuring the long-term reliability of the connection, and making the fit between the light-shielding component and the PCB assembly more stable and reliable.

[0016] In one embodiment, the mating hole includes a first adapter hole and a second adapter hole, which are connected. The mating part can mate with both the first adapter hole and the second adapter hole respectively. The configuration of the first and second adapter holes provides multi-level guidance for the mating part, ensuring more precise and stable assembly of the light-shielding component and the PCB board assembly. This design increases the contact area and mechanical engagement points at the connection, improving the stability of the connection between the PCB board assembly and the light-shielding component.

[0017] In one embodiment, the mating part includes a first adapter and a second adapter. The first adapter is disposed on the light-shielding part and mates with a first adapter hole. The second adapter is disposed on the first adapter and mates with a second adapter hole. The mating of the first adapter with the first adapter hole and the mating of the second adapter with the second adapter hole forms a double mechanical engagement, significantly enhancing the connection strength between the light-shielding component and the PCB board assembly. The first and second adapters can be elastic, making assembly simpler and more convenient.

[0018] In one embodiment, the first adapter hole penetrates the PCB board assembly. Because the first adapter hole penetrates the PCB board assembly, the first adapter portion that mates with the first adapter hole also penetrates the PCB board assembly, resulting in a more secure fit.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0042] like Figure 1-15 As shown, this embodiment discloses a light-transmitting panel structure, including: a PCB board assembly 1; a lamp body assembly 2, the lamp body assembly 2 being disposed on the PCB board assembly 1; a light-shielding assembly 3, the light-shielding assembly 3 being disposed on the PCB board assembly 1, the light-shielding assembly 3 surrounding the lamp body assembly 2, the light-shielding assembly 3 having a light transmission channel 301, and an opening 302 at one end of the light-shielding assembly 3 away from the PCB board assembly 1, the opening 302 communicating with the light transmission channel 301; and a panel assembly 4, the panel assembly 4 being disposed on the light-shielding assembly 3, the panel assembly 4 closing the opening 302, the panel assembly 4 having a hollow area, the hollow area being in the shape of text or a pattern, and the portion of the panel assembly 4 with the hollow area being made of a light-transmitting material.

[0043] This application discloses a light-transmitting panel structure. The panel assembly 4 has sections made of light-transmitting material in the form of text or patterns, allowing light emitted from the lamp assembly 2 to pass through and display the text on the panel assembly 4. This design has multiple functions, such as improving user visibility in low light conditions and serving a decorative purpose. A light-shielding component 3 surrounds the lamp assembly 2 and has a light transmission channel 301, which directs the light emitted from the lamp assembly 2 to a specific area of ​​the panel assembly 4. This design prevents light scattering in all directions, ensuring clear and bright display of the light-transmitting text or patterns. The panel assembly 4 can use light-transmitting material only in the areas with cut-out text or patterns, creating a strong contrast between the displayed content and the background. Alternatively, the entire panel assembly 4 can be made of light-transmitting material, with the cut-out areas distinguished by other colors.

[0044] like Figure 3As shown, in addition to the features of the above embodiments, this embodiment further includes a light-transmitting plate 5, which is disposed on the light-shielding component 3 and located within the light transmission channel 301. The light-transmitting plate 5 is located between the lamp body component 2 and the panel component 4. Because the light-transmitting plate 5 is located between the lamp body component 2 and the panel component 4, the light emitted by the lamp body component 2 can be directly transmitted to the panel component 4 after passing through the light-transmitting plate 5, thereby displaying the text or patterns on the panel component 4. The light-transmitting plate 5 enhances the overall strength of the product. The light-transmitting plate 5 is made of a light-transmitting material, and the light-shielding component 3 is made of an opaque material. This design allows for the injection molding of the light-transmitting plate 5 using a light-transmitting material in the first mold, and then the injection molding of the light-shielding component 3 using an opaque material in the second mold. This method allows for the production of both the light-transmitting plate 5 and the light-shielding component 3 through two injection molding processes. Light-transmitting materials can be used in areas where light transmission is needed, and opaque materials can be used in areas where light transmission is not needed, making the production process simpler and more convenient.

[0045] like Figure 3-4 and Figure 6-7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the light-shielding component 3 is provided with an adapter groove 303, the adapter groove 303 is located on the inner side of the light-shielding component 3, and the light-transmitting plate 5 cooperates with the adapter groove 303. The cooperation between the light-transmitting plate 5 and the adapter groove 303 improves the overall assembly firmness and prevents loosening or displacement during use. Moreover, the adapter groove 303 can be formed during injection molding; for example, the side of the light-transmitting plate 5 can be embedded into the adapter groove 303 and injection molded tightly, making manufacturing simple and convenient, simplifying the assembly process, and improving production efficiency.

[0046] like Figure 3-4 and Figure 6-7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the adapter groove 303 is arranged around the inner side of the light-shielding component 3. By arranging the adapter groove 303 around the inner side, the light-transmitting plate 5 can obtain uniform support and restraint at all circumferential positions, avoiding assembly deviations or loosening caused by uneven local stress. This design makes the connection between the light-transmitting plate 5 and the light-shielding component 3 tighter, improving the mechanical strength and impact resistance of the overall structure. The surrounding groove can be formed in one step using a mold; after the light-transmitting plate 5 is embedded, it can be directly injection molded and covered without additional processing steps, further simplifying the production process and improving the yield rate.

[0047] like Figure 15As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the light-transmitting plate 5 is provided with positioning holes 501, and the number of positioning holes 501 is multiple, with multiple positioning holes 501 located on the same side of the light-transmitting plate 5. By having multiple positioning holes 501 located on the same side of the light-transmitting plate 5, the positional accuracy of the light-transmitting plate 5 in the second mold is ensured, avoiding injection molding offset. This design eliminates the need for additional positioning structures, achieving precise positioning using existing openings in the light-transmitting plate 5, reducing mold complexity and production costs. Moreover, positioning is simple and convenient, improving production efficiency.

[0048] like Figure 3 , Figure 6 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of lamp body components 2 is multiple, all of which are disposed on the PCB board assembly 1 and located within the light transmission channel 301, and all of which are located on the side of the PCB board assembly 1 facing the panel assembly 4. By having multiple lamp body components 2 within the light transmission channel 301, the light transmitted to the panel assembly 4 is more abundant, ensuring that the display brightness of the translucent text or pattern meets the visibility requirements under different ambient light conditions. The multiple lamp body components 2 are integrated on the same PCB board assembly 1, eliminating the need for additional wiring or support structures, thus saving space and facilitating assembly and maintenance.

[0049] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the light-shielding component 3 is snapped into the PCB board assembly 1. By snapping the light-shielding component 3 into the PCB board assembly 1, rapid positioning and fixing of the light-shielding component 3 and the PCB board assembly 1 are achieved, simplifying the assembly process and improving production efficiency. This design ensures a tight fit between the light-shielding component 3 and the PCB board assembly 1, preventing loosening or displacement due to vibration or external force during use.

The mating hole 101 and the light-shielding component 3 form a mechanical alignment reference, ensuring accurate installation of the light-shielding component 3 and the PCB board assembly 1, and improving assembly precision. This design enables a firm connection between the light-shielding component 3 and the PCB board assembly 1, preventing loosening due to vibration or external force during use.

[0051] like Figure 3 , Figure 5 and Figure 11-12As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the light-shielding component 3 includes a light-shielding part 31, a mating part 32, and a limiting part 33.

The mating part 32 is disposed on the light-shielding part 31 and mates with the mating hole 101. The limiting part 33 is disposed on the mating part 32 and is located at the end of the mating part 32 away from the light-shielding part 31. By surrounding the lamp body assembly 2 with the light-shielding part 31, light divergence can be reduced, making light transmission more concentrated. By mating with the mating hole 101, the stability and reliability of the assembly of the light-shielding component 3 and the PCB board assembly 1 can be improved. By the limiting part 33 being located at the end of the mating part 32 away from the light-shielding part 31, the light-shielding component 3 can be prevented from detaching from the PCB board assembly 1, further improving the reliability of the assembly.

[0052] like Figure 2-3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the light-shielding part 31 abuts against one side of the PCB board assembly 1, and the limiting part 33 abuts against the other side of the PCB board assembly 1.

This design effectively prevents axial displacement of the PCB board assembly 1 due to vibration or external force during use.

[0053] like Figure 2-3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the limiting part 33 is located on the outside of the PCB board assembly 1. By positioning the limiting part 33 on the outside of the PCB board assembly 1, the limiting part 33 abuts against the PCB board assembly 1, thereby effectively restricting the degree of freedom of the PCB board assembly 1, effectively preventing the light-shielding component 3 from separating from the PCB board assembly 1 in the axial direction, ensuring the long-term reliability of the connection, and making the cooperation between the light-shielding component 3 and the PCB assembly more stable and reliable.

[0054] like Figure 3 , Figure 5 and Figure 13-14As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mating hole 101 includes a first adapter hole 1011 and a second adapter hole 1012, the first adapter hole 1011 and the second adapter hole 1012 are connected, and the mating part 32 can mate with the first adapter hole 1011 and the second adapter hole 1012 respectively. The configuration of the first adapter hole 1011 and the second adapter hole 1012 provides multi-level guidance for the mating part 32, ensuring a more precise and stable assembly process between the light-shielding component 3 and the PCB board assembly 1. This design increases the contact area and mechanical engagement points at the connection, thereby improving the stability of the connection between the PCB board assembly 1 and the light-shielding component 3.

[0055] like Figure 3 , Figure 5-6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mating part 32 includes a first adapter part 321 and a second adapter part 322.

Through the mating of the first adapter part 321 with the first adapter hole 1011 and the mating of the second adapter part 322 with the second adapter hole 1012, a double mechanical engagement is formed, significantly enhancing the connection strength between the light-shielding component 3 and the PCB board assembly 1. The first adapter part 321 and the second adapter part 322 can be elastic, making assembly simpler and more convenient.

[0056] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first adapter hole 1011 penetrates the PCB board assembly 1. Because the first adapter hole 1011 penetrates the PCB board assembly 1, the first adapter portion 321, which mates with the first adapter hole 1011, also penetrates the PCB board assembly 1, making the fit more secure.
