Abstract
Description
Technical Field
[0001] The present invention relates to the field of flexible deformation interfaces, in particular to a deformation unit and a flexible deformation interface based on the cross airflow blockage principle. Background Art
[0002] Existing flexible deformable interfaces often use specially designed materials, and then use electric current, heating, or catalysts such as chemical reagents to control the degree of deformation of each area. They are not advantageous in terms of the acquisition and preparation of raw materials, the difficulty of manufacturing and processing, and the subsequent maintenance costs. At the same time, because the driving conditions are often accompanied by large currents, high temperatures and toxic reagents, there are certain problems with the security and real-time performance of the interaction. In addition, the existing technology also has the problems of high processing and maintenance difficulty, low human-computer interaction security, and poor real-time performance. Summary of the Invention
[0003] In order to solve the above technical problems existing in the prior art, the present invention proposes a deformation unit and a flexible deformation interface based on the principle of cross airflow blockage. The specific technical solution is as follows: A deformation unit based on the principle of cross-airflow blockage includes a top deformation layer, a main airflow layer and a cut-off airflow layer arranged in sequence from top to bottom; the top deformation layer has a top deformation membrane, and the cut-off airflow layer has a bottom deformation membrane; a transverse airflow flows into the main airflow layer, and a longitudinal airflow flows into the cut-off airflow layer; after the longitudinal airflow flows into the cut-off airflow layer, the bottom deformation membrane expands and bulges upward to intercept the transverse airflow of the main airflow layer, so that the transverse airflow enters the top deformation layer and deforms the top deformation membrane to protrude.
[0004] Furthermore, the top deformation layer also includes a top bracket, the top bracket has an internal cavity, an air inlet is opened at the bottom of the top bracket, the air inlet is communicated with the cavity, and the top deformation membrane covers the top of the cavity.
[0005] Furthermore, the main airflow layer is formed between the top bracket and the bottom deformable membrane.
[0006] Furthermore, the airflow-blocking layer further comprises a bottom bracket, and the bottom deformable membrane is arranged on the bottom bracket in an arched shape, forming a through hole therebetween, through which the longitudinal airflow flows.
[0007] Furthermore, the bottom bracket and the top bracket are provided with connecting pieces around them, and are fixedly connected through the connecting pieces.
[0008] A flexible deformation interface is formed by arranging a plurality of the above-mentioned deformation units in an array form.
[0009] Furthermore, in the cut-off airflow layer, the through-hole opening located on the front side of the flexible deformation interface is open, and the through-hole opening located on the rear side of the flexible deformation interface is blocked. Longitudinal airflow enters from the front through-hole opening, and the airflow fills the through-hole space to cause the bottom deformation membrane to expand as a whole and push up until it contacts the top bracket.
[0010] Furthermore, in the main airflow layer, there is no blocking arrangement on the left and right sides of the flexible deformation interface, and a lateral airflow is introduced from the air inlet side of the flexible deformation interface to fill the space between the top bracket and the bottom deformation membrane.
[0011] Beneficial effects: 1. The flexible deformation interface of the present invention is applied to the depth Figure 3 In the field of 3D display, since each independently deformable unit can change its deformation degree through air pressure control, it can achieve a 3D display of content with depth information (or content that can be represented as depth information), making it more intuitive. Secondly, the flexible deformable interface of the present invention can be used in the field of human-computer interaction, where information needs to be transmitted through touch or other means, such as medical rehabilitation, allowing users to obtain information through multiple methods such as observation and touch.

DETAILED DESCRIPTION
[0013] In order to make the purpose, technical solution and technical effect of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
[0014] like Figures 1 to 3As shown, a deformation unit based on the cross airflow blocking principle of this embodiment includes a top deformation membrane 1, a top bracket 2, a bottom deformation membrane 3, a bottom bracket 4, and connecting parts 5 arranged around it in sequence from top to bottom.
[0015] The bottom deformable membrane 3 is arranged on the bottom bracket 4 in an arched shape, forming a through hole therebetween and constituting a cut-off airflow layer 9, into which a longitudinal airflow can flow.
[0016] A main airflow layer 8 is formed between the top support 2 and the bottom deformable membrane 3 , and a transverse airflow flows into the main airflow layer 8 .
[0017] like Figure 4 As shown, the top bracket 2 has a cavity 6 inside, and an air inlet 7 is opened at the bottom of the top bracket 2. The air inlet 7 is communicated with the cavity 6, and the top deformable membrane 1 covers the cavity 6.
[0018] This embodiment also provides a flexible deformation interface, which is formed by arranging a plurality of the above-mentioned deformation units in an array. Specifically, the through hole opening at the front side of the flexible deformation interface is open, and the through hole opening at the rear side is blocked, such as Figure 5 and Figure 6 As shown, longitudinal airflow is introduced from the front through-hole, filling the through-hole space. When the airflow reaches the rear side, since this side is blocked, the bottom deformable membrane 3 expands and pushes up until it contacts the top bracket 2.
[0019] In the main airflow layer 8, there are no blockages on the left or right sides of the flexible deformable interface. Transverse airflow enters from the right side of the flexible deformable interface, filling the space between the top bracket 2 and the bottom deformable membrane 3, allowing airflow to flow out from the left side. When the longitudinal airflow in the intercepted airflow layer 9 is large, causing the bottom deformable membrane 3 to press against the top bracket, the transverse airflow in the main airflow layer 8 at the corresponding position is intercepted. The intercepted airflow enters the internal cavity of the top bracket 2, causing the top deformable membrane 1 above it to deform and protrude. At this time, the airflow in the intercepted airflow layer 9 is reduced, the deformation of the bottom deformable membrane 3 is reduced, the gap between it and the top bracket 2 is increased, and the deformation of the top deformable membrane 1 is reduced, thus achieving deformation control.
[0020] From the above, it can be seen that when the horizontal airflow of a certain row of main airflow layer 8 and the longitudinal airflow of the cut-off airflow layer 9 are connected, the deformation units at the intersection will start working, so all the deformation units on a single flexible deformation interface can be controlled by traversing row by row.
[0021] Starting from the end farthest from the main airflow, first connect the cut-off airflow, i.e. the longitudinal airflow, farthest from the main airflow end, and then connect the transverse airflow of the corresponding column of the unit in the row that needs to be deformed. After the deformation is complete, keep the longitudinal airflow in the row connected, continue to connect the second row of longitudinal airflow, and connect the transverse airflow of the corresponding column, and so on, until all units that need to be deformed are deformed; after stopping the ventilation of all longitudinal airflows, the deformation will be restored. In this way, it will be possible to control all deformed units, thereby realizing the independent control of deformation of each area of the flexible deformation interface.
[0022] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the implementation process of the present invention is described in detail above, it is still possible for those familiar with the art to modify the technical solutions described in the above examples or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
