Description

Technical Field

[0001] The present application relates to the field of 3D display technology, and in particular to a naked-eye 3D mobile phone case. Background Art

[0002] With the advancement of technology, glasses-free 3D technology, as a new advancement in visual experience, has become a part of consumers' daily lives. Initial built-in glasses-free 3D display technology was limited by high costs and device compatibility. The rise of external glasses-free 3D technology has brought new solutions to the market, including glasses-free 3D phone cases, which combine a 3D visual experience with phone protection. To view glasses-free 3D, simply attach the case to the front of the phone and use the built-in 3D software. When not viewing glasses-free 3D, flip the case over to the back of the phone, providing protection from drops and bumps during daily use.

[0003] However, this approach presents some challenges. In actual use, a dropped phone directly impacts the plastic case, transferring force to the spacer. Because the spacer material often lacks sufficient toughness to absorb these impacts, it can easily break, compromising the product's functionality and durability. Deformation of the 3D prism structure during this process is another significant issue. Lateral force from the plastic case can easily cause the assembly to deform, disrupting its original regular cylindrical structure and ultimately impairing the clarity and three-dimensionality of the 3D image.

[0004] In summary, naked-eye 3D mobile phone cases have shown potential in promoting the popularization of naked-eye 3D technology and improving user experience, but still need to further solve technical problems such as isolation piece rupture and 3D prism structure deformation, by continuously optimizing material selection and improving structural design.

[0025] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the accompanying drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] As used herein, the terms "comprise," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0027] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] See also Figures 1 to 3, the naked-eye 3D mobile phone case in a preferred embodiment of the present application needs to be further explained. The drawings only expand the main structure, that is, how to design a drop-proof mobile phone case, and do not further specifically involve the modification of the key positions of buttons, cameras, flash lights, sensors, etc. The above structure can be avoided in places where avoidance is required according to conventional design. In order to provide a specific setting method for the naked-eye 3D plug-in device, this application implements it on the mobile phone case, and at the same time further realizes dual protection against the breakage of the isolation sheet 200 and the deformation of the 3D prism structure. The naked-eye 3D mobile phone case includes an outer shell 100, an isolation sheet 200 and a prism structure layer 300.

[0029] The outer shell 100 includes a coupling portion 110 and a mounting groove 120 that match the mobile phone. The outer shell 100 is buckled to the mobile phone through the coupling portion 110. The coupling portion 110 in this application refers to any possible way to set the outer shell 100 on the mobile phone. As long as the coupling between the outer shell 100 and the mobile phone can be achieved, it is considered a match. The outer shell 100 serves as the main structure of the mobile phone case and mainly achieves a close match and a stable connection with the mobile phone. Specifically, the outer shell 100 can include a multi-dimensional adaptive coupling portion 110. The coupling portion 110 is not limited to a simple size match, but can also include elastic buckles, anti-slip textures, etc. Of course, it can also include reserved holes in positions such as cameras and charging ports to ensure that the mobile phone case can fit tightly to the mobile phone without affecting the normal use of the original functions of the mobile phone. As for the material of the outer shell 100, silicone, TPU, PC can be mainly used. Silicone, cloth, hard plastic, leather and other materials can also be used. In terms of drop resistance, the following two conditions must be met at the same time: it will not break after falling; the smaller the deformation compression, the better. The appropriate material can be obtained by conducting preliminary research and development tests on different materials.

[0030] The isolation piece 200 includes a contact portion and an inner side surface. The contact portion of the isolation piece 200 is designed to be filled into the mounting groove 120 on the outer shell 100. The depth and shape of the mounting groove 120 precisely match the contact portion through an interference fit or a limiting structure (such as a slot, a bump, etc.).

[0031] The mounting groove 120 cooperates with the contact portion to relatively fix the isolation plate 200 and the outer shell 100, thereby achieving relative fixation of the isolation plate 200 and the outer shell 100 and ensuring the stability of the isolation plate 200 in the mounting groove 120. The concept of relative fixation means that although the isolation plate 200 and the outer shell 100 are not rigidly connected, no displacement occurs during normal use, thereby ensuring the precise positioning and protection of the prism structure layer 300.

[0032] The prism structure layer 300 is arranged on the inner side surface of the isolation plate 200. The prism structure layer 300 is arranged on the inner side surface of the isolation plate 200. This layout effectively avoids direct contact between the prism structure layer 300 and the external environment, reducing potential damage such as dust and scratches. The prism structure layer 300 is made of high-precision optical materials and forms a regular cylindrical lens array through micro-nano processing technology, which cooperates with the picture to produce a 3D stereoscopic visual effect. It is arranged on the inner side of the isolation plate 200, which not only protects the integrity of the prism structure, but also further enhances the resistance to external impact through the buffering effect of the isolation plate 200.

[0033] Among them, the contact part fills part of the space of the installation groove 120, and a buffer cavity 400 is formed in the installation groove 120. After the contact part fills part of the space of the installation groove 120, a buffer cavity 400 is naturally formed between the two through size design. The buffer cavity 400 can absorb and disperse the impact force through the compression deformation of the buffer cavity 400 when the mobile phone suffers an accidental fall or collision, thereby effectively protecting the isolation plate 200 and the prism structure layer 300 from damage. The setting of the buffer space is directly realized through the installation groove 120 of the outer shell 100, and multiple structures (buffer cavity 400 and installation groove 120) can be realized in one manufacturing step, which simplifies the structure and manufacturing process.

[0034] In terms of appearance symmetry and functional design, the outer shell 100 of the present application is selected to have a centrally symmetrical structure. The centrally symmetrical characteristic ensures that it can present a consistent appearance in any direction, can achieve compatibility in the use and storage scenarios of external devices, and provides balanced support and protection for internal components such as the isolation sheet 200 and the prism structure layer 300. The centrally symmetrical structure has a uniform weight distribution in all directions, and the various components that cooperate with the outer shell 100 (such as the isolation sheet 200, etc.) can also obtain more balanced support and layout, which helps to protect these precision components from external impacts and ensure that they can stably perform their respective functions. Since the centrally symmetrical structure does not rely on a specific direction or angle, the outer shell 100 can more easily adapt to mobile phones of different models and sizes, improving the versatility and compatibility of the mobile phone case.

[0035] Specifically, the prism structure layer 300 is not in direct contact with the outer shell 100, and is provided with the isolation sheet 200. Figure 1-3The value of D3 shown in the figure is greater than 0, which keeps the prism structure layer 300 in a non-direct contact state with the outer shell 100, avoiding friction and wear that may be caused by direct contact, ensuring the stability and safety of the prism structure layer 300, and preventing the degradation of optical performance. By avoiding direct contact with the outer shell 100, the wear and tear that may be caused by external impact or daily use is reduced, thereby effectively extending the service life of the prism structure layer 300 and ensuring the continuity and stability of the naked eye 3D visual effect. Direct contact may cause tiny scratches or deformations on the prism surface, which in turn affects the refraction and reflection of light, reducing the clarity and three-dimensional sense of the 3D visual effect. The non-direct contact design avoids this problem and ensures that the optical performance of the prism structure layer 300 is always in the best state.

[0036] Specifically, the width of the prismatic structure layer 300 is greater than the width of the phone screen. The prismatic structure layer 300 is designed to have an extended width, extending beyond the boundaries of the phone screen to cover the entire visible area of ​​the phone screen. It also extends to both sides to achieve a wider optical effect and visual coverage. When the prismatic structure layer 300 matches the width of the phone screen, optical distortion is likely to occur at the edges of the screen, affecting the continuity of the 3D effect. However, by expanding the width of the prismatic structure layer 300, light refraction in the edge areas can be more effectively controlled, thereby reducing distortion and improving the visual effect.

[0037] Please see further Figure 2 In order to enhance the stability between the contact portion and the mounting groove 120 and optimize the mechanical properties and stability of the overall structure, it was found through experiments that the width of the contact portion and the mounting groove 120 is greater than twice the width of the buffer cavity 400. Specifically, in terms of the value, Figure 1 、 Figure 2 In the structural diagram shown, the width of the contact portion in contact with the mounting groove 120 is the value of D2 minus the value of D1, which is greater than twice the width of the buffer cavity 400, that is, greater than twice the value of D1. In this case, it has a better reinforcement effect, increases the contact width between the contact portion and the mounting groove 120, increases the relative contact area between the two, and thus enhances the connection strength, making the prism structure layer 300 or related components more stable in the mounting groove 120 and less likely to be displaced or fall off due to external forces.

[0038] Specifically, the amount of lateral compression of the buffer cavity 400 during deformation is less than its width. When the buffer cavity 400 is deformed by external impact or pressure, its lateral compression (i.e., the width direction perpendicular to the impact direction) is limited to a range significantly smaller than the original width of the buffer cavity 400. By selecting materials with a high elastic modulus or excellent compression resistance, combined with precise geometric design, impact energy is effectively dispersed and absorbed, reducing lateral compression deformation and thus protecting the separator 200 from damage. Furthermore, the buffer cavity 400's resistance to lateral compression can be further enhanced by precisely controlling its wall thickness, shape factor (e.g., aspect ratio), and possible internal support structure.

[0039] Specifically, the bending strength of the isolation film 200 is greater than 90Mpa. The isolation film 200 with high bending strength can more effectively resist the impact of external forces and the accumulation of internal stress, and prevent structural damage or failure due to material failure. By selecting the isolation film 200 with high bending strength, the prism structure layer 300 is protected from deformation during use, and the prism structure layer 300 is protected from being affected by moisture during use, causing the column mirror to expand or shrink. The isolation film 200 has high rigidity and is not easy to deform. It also has moisture-proof ability and optical properties. Materials with the above properties such as glass and acrylic panels can be selected.

[0040] Specifically, the mounting groove 120 is a fitted groove or an open groove, wherein the opening height of the open groove is greater than the thickness of the isolation sheet 200. The specific method of the open groove is as follows: Figure 3 As shown in the figure, the design feature of the interlocking groove is that the groove spacing matches the thickness of the isolation sheet 200. Through precise tolerance control, the isolation sheet 200 is tightly interlocked with the groove body. The interlocking groove can effectively prevent the isolation sheet 200 from moving under vibration or external force. Unlike the interlocking groove, the opening height of the open groove is designed to be greater than the thickness of the isolation sheet 200. Figure 3 In the figure, the value of H2 is greater than that of H1. This design allows a certain amount of room for error during the installation process, which facilitates quick positioning and adjustment of the position of the isolation plate 200. The open groove also facilitates subsequent maintenance and replacement operations. The open groove can connect the isolation plate 200 to the outer shell 100 by bonding.

[0041] Specifically, it also includes an exhaust hole connected to the buffer chamber 400. The design of the exhaust hole allows the excess gas or pressure accumulated in the buffer chamber 400 to be released in a timely manner, thereby maintaining the pressure in the chamber within a stable and safe range. The design of the exhaust hole can be adjusted and optimized according to specific application requirements. For example, by changing the size, number or position of the exhaust hole, the gas flow rate in the buffer chamber 400 can be controlled.

[0042] Specifically, the outer shell 100 includes an anti-slip strip, which is made of a material with a high friction coefficient and can significantly increase the friction between the outer shell 100 and the mobile phone. The anti-slip strip is arranged on the part that contacts the mobile phone. The anti-slip strip can be integrated inside the outer shell 100 to adapt to mobile phone models of different sizes and shapes, so that the same outer shell 100 can be suitable for multiple mobile phones.

[0043] As can be seen from the above, this application proposes a naked-eye 3D mobile phone case that integrates a naked-eye 3D plug-in device into the mobile phone case, while achieving dual protection for the mobile phone and 3D display components. It is mainly composed of an outer shell, an isolation plate and a prism structure layer. Through design and coordination between the various components, they together constitute a stable and efficient naked-eye 3D plug-in component. The outer shell serves as the main structure, and adopts a joint design to ensure a close match and a firm connection with the mobile phone. The outer shell material meets the anti-fall requirements, that is, it does not break after falling and the deformation compression is small. The isolation plate contact part is precisely filled in the mounting groove of the outer shell, and is firmly fixed by an interference fit or a limit structure. The buffer cavity design between the mounting groove and the contact part effectively absorbs and disperses the impact force, protecting the prism structure layer from damage. The prism structure layer is arranged on the inner side of the isolation plate, made of high-precision optical materials, and a cylindrical lens array is formed by micro-nano processing technology. The non-direct contact design avoids friction and wear between the prism structure layer and the outer shell, thereby extending the service life.

[0044] To further enhance stability, the contact width between the contact portion and the mounting slot is optimized to be greater than twice the width of the buffer cavity, thereby increasing the connection strength. The lateral compression of the buffer cavity during deformation is strictly controlled to protect the isolation sheet from damage. The isolation sheet itself has high bending strength, moisture-proof ability, and excellent optical properties, ensuring the stability and safety of the prism structure layer. In summary, the naked-eye 3D mobile phone case in this application achieves comprehensive protection for the mobile phone and 3D display components through structural design and material selection, while providing an excellent naked-eye 3D visual experience, meeting the user's dual needs for mobile phone protection and entertainment functions.

[0045] The above is only a specific implementation of the present application. Any other improvements made based on the concept of the present application are considered to be within the scope of protection of the present application.
