Abstract
Description
Technical Field
[0001] This utility model belongs to the field of optical display equipment technology, specifically relating to a curved semi-transparent uniform light-emitting structure, and also to an intelligent companion robot having the curved semi-transparent uniform light-emitting structure. Background Technology
[0002] In recent years, with the increasing demands of smart terminal products for human-computer interaction experience, curved semi-transparent interfaces that integrate display and light-emitting functions have gradually become an important design trend for high-end smart devices (such as smart companion robots). This type of structure can achieve the integrated expression of information display and ambient lighting effects during device standby or interaction, enhancing the product's technological feel and emotional interaction capabilities.
[0003] In practice, a common approach is to place a dot matrix LED light source on the back of a curved display screen and use a uniform light structure to transform the discrete light source into a uniform visual effect. However, due to the special nature of the curved geometry, existing technologies face challenges in achieving uniform light output, and uneven light output has become a key bottleneck restricting visual quality.
[0004] Specifically, existing structures mostly follow the planar uniform light design concept, directly attaching the planar light guide plate or diffuser plate to the inside of the curved display screen. However, due to the curvature changes in different areas of the curved surface, the distance from the light source to the display screen surface is inconsistent. The propagation path, refraction angle and diffusion range of light at different positions are different, which easily produces the phenomenon of bright center, dark edge or local light spot aggregation. Utility Model Content
[0005] This invention addresses the aforementioned problems in the existing technology by proposing a curved, semi-transparent, uniform light-emitting structure and an intelligent companion robot.
[0006] This utility model can be achieved through the following technical solutions:
[0007] A curved, semi-transparent, uniform light-emitting structure, comprising:
[0008] Curved display screen;
[0009] The light-emitting component includes a dot matrix screen and a light-emitting plate. Both the dot matrix screen and the light-emitting plate are curved structures, and their curvatures are the same as the curvature of the curved display screen. The dot matrix screen, the light-emitting plate, and the curved display screen are sequentially attached to each other.
[0010] The light-emitting plate has a plurality of light-transmitting holes evenly distributed therefrom, and the vertical distance from each light-transmitting hole to the inner surface of the curved display screen is equal.
[0011] As a further improvement of this utility model, the outer end face of the light-emitting plate is set as a smooth surface and is used to fit against the inner end face of the curved display screen;
[0012] The inner end face of the light-emitting plate is provided with an inwardly protruding perforated plate, and each of the light-transmitting holes is evenly distributed on the perforated plate and penetrates the light-emitting plate and the perforated plate.
[0013] As a further improvement of this utility model, each LED bead on the dot matrix screen is respectively housed in each of the light-transmitting holes on the perforated plate.
[0014] As a further improvement of this utility model, the light-emitting component further includes a mounting bracket, the light-emitting plate is connected to the mounting bracket, and the dot matrix screen is located between the light-emitting plate and the mounting bracket and is connected to the mounting bracket.
[0015] As a further improvement of this utility model, the mounting surface of the mounting bracket is set as a curved surface and is used to mount the dot matrix screen and the light-emitting plate.
[0016] As a further improvement of this utility model, the mounting surface of the mounting bracket has a recessed mounting groove, and the dot matrix screen is embedded in the mounting groove.
[0017] As a further improvement of this utility model, the light-emitting area composed of each of the light-transmitting holes on the light-emitting plate is located within the area defined by the mounting groove.
[0018] As a further improvement of this utility model, the mounting groove is provided with a protruding positioning post, and the dot matrix screen is provided with a positioning hole. After the dot matrix screen is embedded in the mounting groove, the positioning post is inserted into the positioning hole.
[0019] As a further improvement of this utility model, the mounting surface of the mounting bracket is also provided with an insertion port, which is distributed in the outer area of the mounting groove. At the same time, fastening plates are provided on both sides of the inner end face of the light-emitting plate, and the fastening plates are inserted into the insertion port and fastened.
[0020] It also provides an intelligent companion robot, including:
[0021] A functional head having an arc-shaped outer shell, the inner cavity of which is used to accommodate a functional component, and at least one opening on the outer wall of the arc-shaped outer shell;
[0022] The aforementioned curved, semi-transparent, uniform light-emitting structure is integrated into the functional head, wherein,
[0023] The light-emitting component is disposed in the inner cavity of the arc-shaped outer shell;
[0024] The curved display screen is embedded in the opening and spliced with the arc-shaped shell to form a complete arc surface, so as to house the light-emitting component inside the functional head.
[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] 1. Achieves highly uniform curved surface light output, significantly improving visual quality.
[0027] By using "co-curvature bonding + equal optical path design", the curvature of the dot matrix screen, the light-emitting plate and the curved display screen are consistent and tightly bonded, ensuring that the vertical distance from each light-transmitting hole to the display screen is equal. This fundamentally eliminates problems such as bright spots, dark areas or blurred edges caused by differences in optical path, and achieves a semi-transparent light emission effect with highly consistent brightness throughout the entire area, without graininess or light crosstalk, resulting in a more natural and beautiful visual performance.
[0028] 2. The highly integrated structure and precise assembly enhance reliability.

It can serve as an information display interface and also present uniform emotional lighting effects (such as expression lights and breathing lights), significantly enhancing the robot's anthropomorphic expression and emotional interaction experience. At the same time, the closed structure effectively protects the internal components, making it suitable for high-end intelligent scenarios such as home care and service reception.

Detailed Implementation
[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.
[0040] like Figures 1-6 As shown, this utility model provides a curved, semi-transparent, uniform light-emitting structure, comprising:
[0041] The curved display screen 100 is designed with a semi-transparent structure, and when light shines on it, a corresponding pattern will be displayed on the curved display screen 100.
[0042] The light-emitting component includes a dot matrix screen 110 and a light-emitting plate 120. Both the dot matrix screen 110 and the light-emitting plate 120 are curved structures, and their curvatures are the same as the curvatures of the curved display screen 100. The dot matrix screen 110, the light-emitting plate 120, and the curved display screen 100 are sequentially attached to each other.
[0043] The light-emitting plate 120 has a number of light-transmitting holes 121 evenly distributed on it. The light emitted from the dot matrix screen 110 passes through each light-transmitting hole 121 and illuminates the curved display screen 100. The vertical distance from each light-transmitting hole 121 to the inner surface of the curved display screen 100 is equal.
[0044] Specifically, the principle of achieving uniform light output from a curved surface is explained as follows:
[0045] The core of achieving uniform light output in this structure lies in the consistent optical path design and conformal structural matching. Since the dot matrix screen 110, the light-emitting plate 120 and the curved display screen 100 have the same curvature and are closely fitted, the path length of the light emitted by the dot matrix screen 110 to the inner surface of the display screen through the light-transmitting hole 121 is exactly the same, thus avoiding the problem of uneven brightness attenuation caused by differences in optical path.
[0046] After passing through the light-emitting plate 120, the light is effectively constrained and guided, and then diffused by the microstructure of the curved display screen 100. Finally, it is visually integrated into a continuous, grain-free, uniform light surface. In addition, the bonding of the three components reduces the air gap, reduces interface reflection and scattering interference, and further improves the uniformity of the light field and the light transmission efficiency.
[0047] Compared to existing technologies, the curved light-emitting structure provided in this embodiment has at least the following advantages:
[0048] 1. Improve light uniformity: Through the design of "equal optical path + co-curvature bonding", the problems of bright center, dark edge or local light spot that are common in curved surface structures are fundamentally eliminated, and the brightness of the whole area is highly consistent.
[0049] 2. Enhance structural reliability and assembly precision: Components with consistent curvature fit together tightly, avoiding light leakage and cross-contamination caused by deformation or misalignment, thereby improving product yield and consistency.
[0050] 3. Suitable for demanding human-computer interaction scenarios: It can be widely used in products with high light quality requirements, such as facial expression display of intelligent robots and ambient lighting of high-end home appliances, to enhance the aesthetics and interactive experience of the products.
[0051] Overall, this application effectively solves the long-standing problem of uneven light emission in curved semi-transparent light sources through structural innovation, achieving high-quality and highly consistent light emission effects, and has significant technological progress and practical value.
[0052] Preferably, the outer end face of the light-emitting plate 120 is set as a smooth surface and is used to fit with the inner end face of the curved display screen 100. This design can ensure that the vertical distance from each light-transmitting hole 121 to the inner surface of the curved display screen 100 is equal. On the other hand, it can effectively reduce interface reflection and light scattering between the light-emitting plate 120 and the curved display screen 100, improve light transmittance, and avoid light distortion caused by surface roughness or gaps, thus ensuring clear and uniform light output.
[0053] In addition, the inner end face of the light-emitting plate 120 is provided with an inwardly protruding perforated plate 122. Each light-transmitting hole 121 is evenly distributed on the perforated plate 122 and passes through the light-emitting plate 120 and the perforated plate 122. Each LED on the dot matrix screen 110 is respectively housed in each light-transmitting hole 121 on the perforated plate 122. It should be noted that the perforated plate 122 forms a local guiding and shielding effect on the light, restricts the lateral diffusion of the light, prevents cross-lighting between adjacent LEDs, and further improves the controllability and uniformity of the light output.
[0054] It is worth mentioning that the light-emitting plate 120 ensures the continuity of the optical interface through its smooth bonding surface, significantly reducing light loss. Meanwhile, the convex perforated plate 122 achieves precise positioning and optical isolation of the dot matrix light source. The two work together to not only enhance the uniformity and softness of the light output, but also improve the assembly accuracy and overall integrity of the structure. This effectively solves common problems in curved surface light emission, such as light leakage, uneven brightness, and ghosting of light spots, thereby improving visual performance and product quality.
[0055] Preferably, the light-emitting assembly further includes a mounting bracket 100, the light-emitting plate 120 is connected to the mounting bracket 100, and the dot matrix screen 110 is located between the light-emitting plate 120 and the mounting bracket 100 and is connected to the mounting bracket 100.
[0056] The mounting surface of the mounting bracket 130 is set as a curved surface, and its curvature is adapted to the curvature of the light-emitting plate 120 and the dot matrix screen 110, so as to facilitate the smooth installation of the dot matrix screen 110 and the light-emitting plate 120 and avoid the decline in optical performance caused by structural deformation or stress concentration.
[0057] Specifically, the mounting surface of the mounting bracket 130 is provided with a recessed mounting groove 131 for embedding the dot matrix screen 110, thereby achieving axial limiting and circumferential fixing, ensuring that the dot matrix screen 110 and the curved surface of the bracket are precisely fitted. A protruding positioning post 1311 is provided inside the mounting groove 131, and a corresponding positioning hole 111 is opened on the dot matrix screen 110. When the dot matrix screen 110 is installed into the mounting groove 131, the positioning post 1311 is precisely inserted into the positioning hole 111, forming a rigid positioning fit.
[0058] This design achieves high-precision, misalignment-proof installation of the dot matrix screen 110, effectively preventing misalignment between the LED beads and the light-transmitting holes 121 of the light-emitting plate 120 during assembly. This ensures that each light-emitting unit is in the optimal light-emitting position, significantly improving light uniformity and optical consistency. At the same time, the cooperation between the positioning post 1311 and the positioning hole 111 enhances structural stability. Furthermore, the pressing of the dot matrix screen 110 by the light-emitting plate 120 effectively prevents loosening caused by vibration, improving product reliability and assembly efficiency.
[0059] Furthermore, the light-emitting area on the light-emitting plate 120, which is composed of various light-transmitting holes 121, is located within the area defined by the mounting groove 131. This design ensures that the light-emitting area completely corresponds to the light-emitting range of the dot matrix screen 110, avoiding light from being projected onto non-display areas or structural edges, thereby preventing stray light, bright edges, or halo phenomena.
[0060] By limiting the light-emitting area to the range of the mounting slot 131, precise matching between the light source and the light-emitting structure is achieved, improving the boundary control capability of the optical system, making the luminous image more regular and clear, and the visual effect better. At the same time, this layout helps to shield the structural features of the non-light-emitting area of the mounting bracket 130, enhancing the overall sense of unity and aesthetics, and is especially suitable for smart terminal products with high requirements for light shape accuracy and appearance quality.
[0061] Preferably, the mounting surface of the mounting bracket 130 is also provided with a socket 132, which is distributed in the outer area of the mounting groove 131. At the same time, the inner end face of the light-emitting plate 120 is provided with fastening plates 123 on both sides. During assembly, the fastening plates 123 are inserted into the sockets 132 and elastically fastened and fixed. This connection method does not require additional fasteners and can achieve quick positioning and reliable fixing of the light-emitting plate 120 on the mounting bracket 130.
[0062] This structural design not only simplifies the assembly process and improves production efficiency, but also ensures the relative positional accuracy between the light-emitting plate 120 and the dot matrix screen 110, preventing light shift or local shading caused by misalignment or loosening.
[0063] Meanwhile, the combination of the socket 132 and the snap-fit plate 123 has a certain structural strength and vibration resistance, which improves the stability and durability of the overall component. Combined with the limiting of the dot matrix screen 110 by the mounting groove 131, a composite fixing method of "embedded + snap-fit" is formed, which further ensures the fit consistency of the multi-layer curved structure in long-term use and is conducive to maintaining the long-term stability of uniform light output effect.
[0064] This utility model also provides an intelligent companion robot, including:
[0065] The functional head 200 has an arc-shaped outer shell 210, the inner cavity of which is used to accommodate functional components (such as the light-emitting component in this application, and power amplifier modules, voice modules, AI modules, etc. not mentioned), and the outer wall of the arc-shaped outer shell 210 has at least one opening 211.
[0066] The aforementioned curved, semi-transparent, uniform light-emitting structure is integrated into the functional head 200, wherein,
[0067] The light-emitting component is pre-installed in the inner cavity of the curved housing 210. The curved display screen 100 is embedded in the opening 211 and seamlessly spliced with the outer surface of the curved housing 210, together forming a smooth and continuous curved appearance surface, thereby completely housing the entire light-emitting component inside the functional head 200.
[0068] This integration method achieves a high degree of integration between the light-emitting display system and the robot's appearance structure, ensuring that the light-emitting area maintains the same curvature and surface texture as the equipment shell, resulting in a clean and beautiful appearance without protrusions or seams, thus enhancing the overall product integrity and industrial design quality.
[0069] Meanwhile, the curved, semi-transparent, uniform light-emitting structure can present soft and uniform emotional lighting effects (such as breathing light and expression light) in non-display mode, and supports the output of graphic or animated information in display mode, which greatly enhances the robot's emotional expression ability and human-computer interaction experience.
