Description

Technical Field

[0001] This utility model relates to the field of flexible electronics technology and robot interaction devices, and in particular to a flexible OLED display structure integrated into a robot mask. Through multi-layer functional material composite and mechanical structure optimization, it achieves high-resolution dynamic display, curved surface adaptive bonding and efficient heat dissipation. It is suitable for intelligent devices such as service robots and bionic robots that require facial expression interaction. Background Technology

[0002] Traditional robot facial display solutions suffer from the following technical bottlenecks:

[0003] Poor surface adaptability: Rigid screens (such as LCDs) cannot fit complex curved surfaces, resulting in gaps between the display unit and the facial contours, which destroys the anthropomorphic effect.

[0004] Low heat dissipation efficiency: When OLEDs operate at high brightness, the heat generation is concentrated. The heat conduction path of traditional graphite sheet heat dissipation structure is discontinuous, which can easily lead to brightness decay and color shift.

[0005] Insufficient mechanical reliability: Vibration stress during robot movement can easily cause rigid collisions between the display module and the support frame, leading to pixel failure.

[0006] Signal interference risk: Long-distance flexible circuit wiring increases sensitivity to electromagnetic interference, leading to image transmission delays or distortion.

[0007] Current improvement solutions, such as the flexible OLED module disclosed in CN119832815A, improve flexibility but fail to address the issue of coordinating heat accumulation and vibration protection optimization. CN222382056U's use of metal mesh reinforcement leads to thermal bridging, reducing heat dissipation efficiency. KR102019008123A's FPC reinforcement only covers the bending area and does not extend to the end connection area. Therefore, an integrated solution that combines display, heat dissipation, and mechanical support is urgently needed. Utility Model Content

[0008] In view of this, the present invention provides a flexible OLED integrated display structure for robot masks, which aims to maintain the long-term stability of high-resolution display brightness through heat dissipation structure and assembly optimization, so as to meet the rendering requirements of fine dynamic facial expression details; to achieve natural curvature fitting between the display module and the robot's facial contour, enhancing the anthropomorphic effect; and to effectively overcome heat dissipation limitations, ensuring the stability of the display module's long-term high-brightness operation.

[0009] The objective of this utility model is achieved through the following technical solution:

[0010] A flexible OLED integrated display structure for a robot mask includes a flexible curved display module for image output, a composite heat dissipation layer attached to the non-display surface of the flexible curved display module, a metal support frame fixed to the back of the composite heat dissipation layer by a buffer adhesive layer, a control circuit board mounted on the metal support frame, and a flexible circuit connecting the control circuit board and the flexible curved display module. The first end of the flexible circuit is connected to the side interface of the flexible curved display module, and the second end is connected to the output interface of the control circuit board.

[0011] By combining a composite heat dissipation layer with a metal support frame in a layered configuration, a continuous and efficient heat conduction path is constructed from the core of the display heat source to the outer frame, fundamentally solving the problems of brightness attenuation and color shift caused by heat accumulation in flexible display modules. The buffer bonding layer, while ensuring reliable mechanical fixation between components, effectively absorbs high-frequency vibration stress generated during robot movement, preventing rigid collision damage between the flexible curved display module and the rigid metal support frame. Using flexible circuitry to directly connect the control circuit board and the flexible curved display module significantly shortens the signal transmission distance, reduces the risk of electromagnetic interference, and thus improves the stability and reliability of image transmission. The overall structure highly integrates high-precision dynamic display, an efficient heat dissipation system, and stable mechanical support, providing a highly reliable dynamic display carrier for the robot's face.

[0012] Preferably, the composite heat dissipation layer is a graphene composite material layer, which is bonded to the flexible curved display module by an optically transparent adhesive.

[0013] The high thermal conductivity of graphene composite materials significantly improves the efficiency of heat diffusion in the vertical direction and prevents the formation of local hot spots; the optically transparent adhesive achieves strong adhesion while avoiding obstruction or refraction interference to the display light path, ensuring that the image output is free of optical distortion; the composite heat dissipation layer has both efficient heat conduction and light transmission maintenance functions, overcoming the problem of heat dissipation area loss caused by the need for openings to avoid the light path in traditional metal heat sinks, and maximizing heat dissipation efficiency in a limited space.

[0014] Preferably, the buffer adhesive layer is a closed-cell foam material layer, covering the space between the composite heat dissipation layer and the metal support frame.

[0015] The micro-airbag structure of the closed-cell foam material can effectively disperse the local compressive stress transmitted by the metal support frame and prevent the composite heat dissipation layer from cracking due to point loads; its low thermal conductivity blocks the heat exchange path between the metal frame and the ambient temperature, avoiding the impact of external thermal shock on the working temperature stability of the display module; the elastic deformation capacity of the foam absorbs the shear stress generated by the multi-degree-of-freedom movement of the robot head, protecting the bonding interface between the composite heat dissipation layer and the display module from being damaged by peeling forces.

[0016] Preferably, the metal support frame is provided with a group of topological weight-reducing holes whose contours match the internal space of the robot mask.

[0017] The topology-based weight-reducing hole group significantly reduces the overall mass and decreases the drive load on the robot's neck while maintaining the structural strength of the key load-bearing areas of the frame. The hole group distribution is optimized based on the internal space characteristics of the mask, providing a passageway for the control circuit board and cables to avoid assembly interference. The air circulation channels formed by the hole structure enhance the heat convection exchange between the frame and the air, helping to improve heat dissipation efficiency. The rounded corner design of the hole edges eliminates stress concentration points and improves the fatigue resistance of the frame.

[0018] Preferably, the deformation area of ​​the flexible circuit is covered by a polymer reinforcing sheet, which extends to the end connection area where the flexible circuit connects to the flexible curved display module.

[0019] The rigidity enhancement of the polymer reinforcing sheet suppresses the tendency of interlayer delamination in the flexible circuit during dynamic bending, and avoids copper foil breakage. The design extending to the end connection area transfers the insertion and extraction stress from the connector solder joint to the reinforcing sheet body, preventing solder joint fatigue failure. The asymmetric wrapping structure of the reinforcing sheet on the flexible circuit increases the bending stiffness of the bending area while retaining the torsional deformation capability in the circuit width direction, adapting to the complex motion trajectory of the robot head.

[0020] Preferably, a metal reinforcement is attached to the back of the end connection area, and the metal reinforcement partially overlaps with the polymer reinforcement sheet. The metal reinforcement is exposed on the back of the flexible circuit, and its edge forms a stepped overlap area with the polymer reinforcement sheet.

[0021] The high modulus of the metal reinforcement effectively suppresses the amplitude of the end connection area in a vibrating environment, reducing the risk of contact impedance fluctuations; the overlapping area with the polymer reinforcement forms a gradual stiffness transition zone, avoiding stress abrupt changes in the flexible circuit at the reinforcement boundary; the local encapsulation of the metal reinforcement on the connector shell enhances the mechanical impact resistance of the plug-in interface, preventing the connector from loosening due to external forces; the overlapping structure achieves rigid-flexible composite reinforcement, taking into account both connection reliability and bending freedom.

[0022] Preferably, the driver chip cluster of the flexible curved display module is disposed on the planar extension portion, and the radius of curvature of the planar extension portion is greater than the radius of curvature of the main body of the flexible curved display module.

[0023] The driver chip cluster is centrally located on the planar extension section, completely avoiding the risk of damage to the chip solder joints and package caused by tensile / compressive stress in the curved bending area; the planar area provides a stable support substrate for the chip, avoiding internal gold wire breakage due to substrate deformation; the centralized arrangement of the chip cluster shortens the interconnect trace length, reducing signal transmission delay and crosstalk; the full contact design between the planar extension section and the heat dissipation layer optimizes the chip heat dissipation path and avoids excessive local temperature rise.

[0024] Preferably, the control circuit board is fixed to the side wing platform of the metal support frame, and the flexible circuit is connected to the display module in a spatial spiral pattern.

[0025] The side-mounted platform allows for a spatially staggered layout between the control circuit board and the display module, avoiding the thickening of their stacked layers. The spatial spiral routing provides additional line length margin, releasing bending stress when the robot's head rotates and preventing the lines from being stretched. The adaptive deformation characteristics of the spiral structure allow the flexible circuit to freely expand and contract in multiple directions, adapting to complex motion trajectories. This routing method isolates the electromagnetic noise of the control circuit board from interfering with the display signal, improving image quality.

[0026] Preferably, the edge contour of the flexible curved display module forms a conformal envelope with the inner edge of the robot mask window.

[0027] The conformal envelope design enables a continuous physical shape match between the display module edge and the mask window, eliminating the assembly gap between the traditional flat screen and the curved window, preventing dust intrusion and light reflection interference; the stepless transition enhances the integrated look of the robot's face and strengthens the anthropomorphic effect; the envelope structure maximizes the use of the window display area and avoids wasting the ineffective edge area; the precise envelope of the module edge reduces the amount of adhesive used and reduces the risk of thermal expansion mismatch.

[0028] Preferably, the edge of the composite heat dissipation layer extends beyond the boundary of the non-display surface of the flexible curved display module, forming a heat diffusion wing.

[0029] The extended portion of the heat diffusion wing plate significantly increases the contact area between the composite heat dissipation layer and the air, enhancing the natural convection heat dissipation capability; the design of the wing plate extending beyond the boundary of the display module directs heat from the core heat source area to the surrounding low-temperature area, balancing the temperature distribution; the wing plate forms a protective covering around the edge of the display module, preventing damage from external mechanical collisions; this extended structure serves as an assembly positioning reference, improving the alignment accuracy between the composite heat dissipation layer and the metal support frame; the thermal deformation space at the free end of the wing plate releases the thermal stress of the material, preventing interlayer delamination.

[0030] The advantages of this utility model compared to the prior art are:

[0031] Improve display performance: Through optimization of heat dissipation structure and assembly, maintain the long-term stability of high-resolution display brightness to meet the rendering requirements of fine dynamic facial expression details;

[0032] Optimize the fit: Achieve a natural surface fit between the display module and the robot's facial contours, enhancing the anthropomorphic effect;

[0033] Overcoming heat dissipation bottlenecks: Effectively overcomes heat dissipation limitations, ensuring the stability of the display module's long-term high-brightness operation. Attached Figure Description
