Abstract
Description
Technical Field
[0001] This invention relates to the field of smart frame technology, specifically a smart photo frame for naked-eye stereoscopic imaging. Background Technology
[0002] Traditional photo frames are mainly used to display static flat photos and have a single function. With the advancement of technology, digital photo frames have emerged, which can play electronic photos in a loop. However, their display effect is still limited to a two-dimensional plane and lacks a sense of three-dimensionality and immersive experience. Naked-eye stereoscopic imaging technology, such as lenticular lens grating or parallax barrier technology, allows users to view stereoscopic images without wearing special glasses.
[0003] However, the effect of naked-eye stereoscopic imaging is highly dependent on the precise distance between the display panel and optical elements (such as lens gratings). Traditional fixed structures cannot adapt to display panels of different sizes or different types of optical elements, resulting in poor stereoscopic effect or crosstalk. In order to ensure the effect of naked-eye stereoscopic imaging, the display panel and stereoscopic imaging module 7 must be tightly fixed by a rigid structure to maintain a precise distance. However, at the same time, the heat generated when the device is working will cause different degrees of thermal expansion of various components (especially metal and plastic parts). This thermal stress will accumulate inside the rigid structure, causing the structure to bend and deform. Furthermore, after the smart frame is assembled, the tolerance accumulation will be serious, affecting the imaging effect.
[0004] To address the above problems, this invention provides a smart photo frame with naked-eye stereoscopic imaging to solve these issues. Summary of the Invention

[0015] Reference Figures 1-5 This invention provides a technical solution: a smart photo frame for naked-eye stereoscopic imaging, comprising: The housing 1 has a front housing 2 installed on one side and a rear housing 3 installed on the other side; Display module 4 is installed inside the housing 1; Adjustment component 5 is installed inside the housing 1 and located around the display module 4; Adjustment frame 6 is fixed on adjustment component 5; The stereoscopic imaging module 7 is fixed inside the adjustment frame 6 and is arranged correspondingly to the display module 4.
[0016] The display module 4 and the stereo imaging module 7 are kept in a non-ventilated state to prevent external dust from entering and affecting the imaging effect. The housing 1 also contains a control system to control the operation of the display module 4 and the adjustment component 5.
[0017] Preferably, the housing 1 has a U-shaped frame inside, with a first step surface 11 for supporting the display module 4 in the middle, and a second step surface 12 around the first step surface 11. The second step surface 12 is connected to the adjustment component 5. The housing 1 has a heat dissipation duct inside, which is integrated into the internal cavity of the U-shaped frame and has an air vent 13.
[0018] In addition, the display module 4 is rigidly connected to the first stepped surface 11 through a thermally conductive adhesive layer, and its heat can be directly conducted to the housing 1 and dissipated through the heat dissipation duct.
[0019] In other words, the heat generated by the display module 4 and its circuit board is directly and efficiently transferred to the housing 1 through the thermal conductive adhesive, and then quickly dissipated through the internal heat dissipation channels, greatly reducing local thermal deformation caused by uneven temperature.
[0020] In a preferred embodiment, the adjustment component 5 includes: The flexible support component 51 is configured in three parts, arranged in an isosceles triangle, with its bottom fixed to the second step surface 12 and its top connected to the adjustment frame 6. The axial fine-tuning components 53 are configured in three, arranged in an inverted isosceles triangle. Their bottoms are fixed to the second step surface 12, and their tops are connected to the adjustment frame 6. The flexible support component 51 and the axial fine-tuning components 53 are arranged symmetrically.
[0021] In the process of realizing this invention, the inventors discovered that the readily conceivable solution of using four or more adjustment points in the prior art introduces a serious "over-positioning" problem. Due to unavoidable manufacturing and assembly tolerances, multi-point adjustment will generate uncontrollable internal stress inside the adjustment frame 6, causing it to warp and deform, thereby damaging optical performance. At the same time, the motion coupling between the actuators of multiple axial fine-tuning components 53 will also complicate the control system and even make it unable to work stably. This invention cleverly transforms it into a statically determinate system by adopting a unique three-point layout, fundamentally eliminating internal stress, ensuring the flatness of the adjustment frame 6, simplifying the control algorithm, and achieving a high-precision and high-stability adjustment effect.
[0022] Specifically, the three axial fine-tuning components 53 form a statically determinate plane for precise positioning, while the three flexible support components 51 are distributed intersectingly at other key locations, forming a stable support base, thus creating the following synergistic effect: The flexible support component 51 located above and the axial fine-tuning component 53 together constrain the top of the stereo imaging module 7, enhancing its vibration resistance; The two flexible support components 51 located below, together with the axial fine-tuning component 53, optimize the distribution of gravity load and provide excellent torsional stiffness. It achieves spatial decoupling and functional complementarity between active positioning and passive support, enabling the system to achieve high adjustment accuracy while also possessing long-term stability and environmental adaptability.
[0023] Preferably, the flexible support component 51 includes: Flexible column 511 is fixed on the second step surface 12; Ball head 512 is fixed on the flexible column 511; The ball head seat 513 is fixed on the adjustment frame 6 and hinged to the ball head 512.
[0024] In other words, during installation, the flexible column 511 is first fixed on the second step surface 12, and then the adjusting frame 6 is pressed onto the ball head 512 through the ball head seat 513.
[0025] Furthermore, when the shell 1 undergoes slight deformation due to thermal expansion and contraction, it will push the flexible column 511 to produce displacement. This displacement will be absorbed by the soft silicone column through its own shear and compression deformation. At the same time, the ball head 512 and the ball head seat 512 joint allow the stereo imaging module 7 to produce slight translation in the X, Y, and Z directions to compensate for the deformation of the shell 1, without transferring stress to the stereo imaging module 7 itself, thereby ensuring the stability of the shape of the stereo imaging module 7 itself.
[0026] Preferably, the flexible column 511 is a silicone column, used to passively release stress in three translational degrees of freedom, while providing stable main support for the stereo imaging module 7.
[0027] In a preferred embodiment, the axial fine-tuning component 53 includes: A micro motor 531 is fixed inside the second step surface 12; The push rod 532 is slidably mounted on the output shaft of the micro motor 531, and is not slidable from the output shaft; The threaded sleeve 533 is fixed inside the second stepped surface 12 and is threadedly connected to the push rod 532; Universal joint 534, one end is fixed to the push rod 532, and the other end is fixedly connected to the adjustment frame 6.
[0028] It should be noted that the adjustment component 5 functions as a whole. The flexible support component 51, through the deformation of its flexible column 511, provides a primary, passive release path for assembly stress and thermal stress mainly from the X and Y directions. At the same time, the universal joint 534 ensures that even when the electromagnetic lock is locked, it mainly provides rigid constraint in the Z direction, while releasing stress in the XY plane. This prevents the deformation of the housing 1 from being forcibly transmitted to the stereo imaging module 7 through the axial fine-tuning component 53, thus achieving comprehensive stress decoupling in collaboration with the flexible support component 51.
[0029] In addition, the axial fine-tuning assembly 53 also includes multiple displacement sensors for detecting the displacement of the push rod 532, and multiple electromagnetic lockers for locking the push rod 532 after it reaches the target position.
[0030] In specific implementation, the initial assembly is as follows: First, the ball head seat 513 of the adjustment frame 6 is fastened onto the ball head 512, and then the universal joint 534 of the axial fine adjustment component 53 is connected to the adjustment frame 6. It should be noted that the stereo imaging module 7 needs to be fixed inside the adjustment frame 6 before installation. At this time, the stereo imaging module 7 has been stably supported, but is in a floating state. Automatic calibration mode: The control system starts the built-in calibration program and plays a specific test pattern on the display panel. The built-in small camera sensor reads the moiré pattern or crosstalk formed after passing through the stereo imaging module 7. Based on the feedback, the control system simultaneously drives the micro motor 531 in the three axial fine adjustment components 53 to precisely adjust the extension and retraction of the push rod 532. Due to the universal joint 534 and the flexible column 511, the stereo imaging module 7 can very smoothly change its relative posture and distance with the display module 4 until the point with the best display effect is found. Locking and Long-Term Operation: After calibration, the control system issues a command to activate all electromagnetic lockers and lock push rod 532. At this time, the entire system changes from an adjustable mode to a high-rigidity mode.
[0031] In subsequent operation, the flexible support component continuously absorbs the deformation stress of the shell 1 caused by thermal expansion and contraction, while the locked axial fine adjustment component 53 ensures that the calibration posture of the stereo imaging module 7 remains unchanged.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
