Embodiment Construction
[0042] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0043] Touch is one of the most important sensory functions of human perception, which not only endows us with the ability to interact with the physical world, but also greatly enriches our daily life, playing an important role in a wide range of applications in robotics, wearable devices, healthcare, etc. effect. In the real world, human beings mainly perceive tactile information through the texture of the surface of objects, so it is easy to distinguish a wide variety of fabrics, appreciate delicate sculptures, and read books in Braille. As a typical tactile feedback device, the texture...

The invention provides a texture presentation device and a manufacturing method thereof, and relates to the technical field of tactile feedback devices. The texture presenting device comprises a flexible film, magnetic units and a film support. The flexible film is provided with a first surface and a second surface which are opposite; the plurality of magnetic units are connected to the first surface; and the membrane support is provided with a plurality of first through holes, and the plurality of magnetic units are inserted into the plurality of first through holes in a one-to-one correspondence mode. According to the texture presentation device, the concave parts or the convex parts can be formed on the surface of the flexible film through movement of the magnetic units under the action of the driving magnetic field, then the uneven surface texture is formed on the surface of the flexible film, and due to the deformable characteristic of the flexible film and the magnetic units, flexibility of the surface layer of the texture presentation device can be achieved, and the flexible texture is presented.
Description
technical field [0001] The present invention relates to the technical field of tactile feedback devices, in particular to a texture rendering device and a manufacturing method thereof. Background technique [0002] Texture refers to the uneven grooves on the surface of an object. For the reproduction of millimeter-scale texture, it is usually realized by changing the surface topography of the texture rendering device. Existing texture display devices mostly use rigid materials as the presentation structure, that is, under the action of a driving magnetic field, the rigid material moves upward to generate certain protrusions, and the rigid protrusions at different positions form an uneven surface, thereby forming a texture. [0003] However, since existing texture presentation devices use rigid materials as presentation units, it is difficult to present the texture of flexible materials, such as the texture of flexible materials such as sofas and leather bags.
