Description

Technical Field

[0001] This invention belongs to the field of lighting technology, specifically a variable-form lighting fixture based on origami mechanics and its design method. Background Technology

[0002] Origami, as a traditional art form imbued with profound cultural heritage, possesses high artistic and practical value due to its unique form and structural characteristics. With its widespread application across various fields, origami has returned to the public eye and become a new direction for innovative research in design. Similarly, in furniture design, origami's unique charm has attracted considerable attention, giving rise to some furniture designs with origami characteristics. However, the current innovation of origami in furniture design remains insufficient; many designs remain at the conceptual level, lacking practical feasibility and the possibility of implementation.

[0003] With societal progress, continuous advancements in science and technology, and rising living standards, people's pursuit of beauty in life has become increasingly strong. Consequently, numerous aesthetically pleasing and uniquely designed lighting fixtures have emerged on the market to enhance the beauty of people's living environments. However, in the current technological field, traditional lighting equipment generally employs a static structural design, resulting in a fixed emission direction and light intensity distribution of the light source, making dynamic adjustments impossible based on the needs of actual application scenarios. This design limits the adaptability and flexibility of the light source, thereby affecting lighting efficiency and the effective use of energy.

[0004] However, most folding lamp products on the market currently have limited form variations, low automation levels, and are inconvenient to disassemble or repair. Furthermore, some lamps are not convenient for logistics and transportation. Summary of the Invention

[0005] The purpose of this invention is to provide a variable-form lamp based on origami mechanics and its design method in order to solve the problems mentioned above.

[0006] The technical solution adopted in this invention is as follows: a variable-form lamp based on origami mechanics and its design method. The variable-form lamp based on origami mechanics includes an origami skeleton assembly, a light-transmitting covering layer, a light source mounting base, and a base. The origami skeleton assembly is a retractable and foldable multi-unit origami structure. The upper end of the origami skeleton assembly is fixedly connected to the light source mounting base, and the lower end of the origami skeleton assembly is fixedly connected to the base. The light-transmitting covering layer is adhered and fixed to the outer surface of the origami skeleton assembly. The origami skeleton assembly and the light-transmitting covering layer constitute a deformable lamp housing.

[0007] By adopting the above technical solution, the origami skeleton component provides a supporting foundation for shape changes and can achieve telescopic folding; the light-transmitting covering layer ensures the lighting function while deforming synchronously with the skeleton; the light source mounting base and the base are fixed at both ends respectively to form a complete lamp structure, which not only meets the lighting needs but also allows for flexible shape adjustment.

[0008] In a preferred embodiment, the origami skeleton assembly is composed of multiple identical origami units joined together by crease hinges. The origami units adopt a diamond crease structure, and wear-resistant flexible pads are provided at the hinges of adjacent origami units.

[0009] By adopting the above technical solutions, the origami unit with the diamond crease structure can achieve stable axial expansion and contraction, and the splicing of multiple units expands the range of shape changes; the wear-resistant flexible pad at the hinge reduces frictional wear between units and avoids jamming or damage during folding.

[0010] In a preferred embodiment, the creases of the origami unit include fixed creases and movable creases, and the fixed creases and movable creases achieve axial extension and retraction of the origami skeleton assembly through the folding and unfolding of the movable creases.

[0011] By adopting the above technical solution, the fixed crease provides stable support for the unit and avoids structural disorder during deformation; the movable crease can be folded and unfolded flexibly, driving the entire origami skeleton assembly to extend and retract along the axis. By controlling the degree of deformation of the movable crease, the height and diameter of the lamp can be precisely adjusted.

[0012] In a preferred embodiment, the light-transmitting covering layer is made of flexible light-transmitting silicone material, and the light-transmitting covering layer is fixed to the edge of the origami skeleton assembly by a hot-pressing process, and the surface of the light-transmitting covering layer is provided with uniformly distributed micro-protrusions.

[0013] By adopting the above technical solutions, the flexible light-transmitting silicone material can deform synchronously with the frame without affecting the adjustment of the lamp shape; the hot pressing process ensures that the covering layer is firmly connected to the frame and avoids falling off; the micro-protrusions can diffuse the light, improve the uniformity of lighting, and avoid glare.

[0014] In a preferred embodiment, the light source mounting base is an annular structure, and an annular groove is provided on the inner side of the light source mounting base. The lower surface of the light source mounting base is movably connected to the upper end of the origami skeleton assembly by bolts.

[0015] By adopting the above technical solution, the annular slot facilitates quick fixation of the light source and makes disassembly and assembly convenient.

[0016] In a preferred embodiment, the base includes a fixed base and a support ring. The support ring is fixedly connected to the lower end of the origami skeleton assembly. The fixed base is a circular metal plate, and the surface of the fixed base is provided with an anti-slip rubber pad.

[0017] By adopting the above technical solutions, the support ring provides a stable connection foundation for the frame and distributes the force; the fixed base made of circular metal plate increases the weight of the base and improves the anti-tipping ability; the anti-slip rubber pad increases the friction with the placement surface and prevents the lamp from shifting during deformation or use.

[0018] In a preferred embodiment, the outer side of the origami skeleton assembly is provided with a plurality of limiting buckles, which are hinged to the origami unit.

[0019] By adopting the above technical solution, the limiting buckle is hinged to the origami unit and can rotate flexibly. When the lamp is adjusted to the target shape, rotating the buckle can lock the relative position of the adjacent origami units, avoiding changes in shape due to external force or its own weight.

[0020] In a preferred embodiment, the limiting buckle includes a buckle body and an elastic bead, and the surface of the folding unit is provided with a positioning hole corresponding to the elastic bead, and the elastic bead engages with the positioning hole.

[0021] By adopting the above technical solution, the engagement of the elastic ball and the positioning hole can achieve multi-position locking.

[0022] In a preferred embodiment, the origami skeleton assembly is integrally stamped from a lightweight aluminum alloy sheet.

[0023] By adopting the above technical solution, the lightweight aluminum alloy material has high strength and light weight, which is easy to manually adjust the shape and can bear the weight of the cladding layer and the light source.

[0024] In a preferred embodiment, the steps include: Step 1: Based on the preset extension stroke and external dimensions of the lamp, design the side length and crease angle of the rhombus origami unit, and determine the hinge method of adjacent units; Step 2: Process the origami skeleton component using lightweight rigid materials, install flexible gaskets at the hinges, and open positioning holes; Step 3: Attach and fix the flexible, light-transmitting covering layer to the outer surface of the origami skeleton assembly, and seal the edges with heat pressing; Step 4: Assemble the light source mounting bracket and the base onto both ends of the origami frame assembly, install the limit buckles, and adjust the locking effect; Step 5: Test the smoothness of deformation of the origami skeleton component and the locking reliability of the limit buckle by manually stretching or compressing the light source mounting bracket, and complete the design.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, axial expansion and contraction deformation is achieved through the cooperation of fixed creases and movable creases. The limiting buckle can lock multiple positions, which not only meets the shape requirements in different scenarios, but also prevents unexpected deformation. The flexible pad at the hinge of the origami unit reduces wear. The material combination of aluminum alloy frame and silicone coating layer ensures structural strength while facilitating long-term folding.

[0026] 2. In this invention, the origami skeleton is integrally stamped and formed, the light source mounting base and the base are detachably connected by bolts, and the light-transmitting covering layer is heat-pressed and fixed for easy replacement; the elastic bead locking structure of the limit buckle can achieve form switching without additional tools, the overall structure has no complex transmission parts, disassembly and maintenance are simple, and maintenance costs are reduced.
