DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. If no specific techniques or conditions are specified in the examples, the techniques or conditions described in the literature in the art or the product instructions are used.

[0050] In the present invention, the instruments and the like used without indicating the manufacturer are all conventional products that can be purchased through regular channels. The raw materials used in the present invention can be processed and purchased in the market.

[0051] Combine the following Figures 1 to 16 The skeleton-type continuity-enhanced tactile display interface of the present invention is described.

[0052] like Figures 1 to 16 As shown, an embodiment of the present invention provides a skeleton-type continuous enhanced tactile display interface, including a substrate 1 and a beam unit, and the beam unit is arranged on the substrate 1. Among them, the beam unit includes a continuous beam 2, a pair of pressing members 3, and a first driver 4. Specifically, the continuous beam 2 is arranged on the substrate 1, and the continuous beam 2 is used to act on the user's skin directly or indirectly, so that the continuous beam skeleton is used as the main output component for generating tactile sensation, contacting and pressing the human skin, and then improving the tactile display effect through the deformation characteristics of the continuous beam 2.

[0053] A pair of clamping members 3 are respectively arranged at the two ends of the continuous beam 2, and the clamping members 3 are connected to the continuous beam 2, for example, by fixing bolts. The clamping members 3 are used to press the ends of the continuous beam 2 onto the base 1, so that the ends of the continuous beam 2 will not separate from the base 1, and the out-of-plane displacement of the ends of the beam is limited. In addition, at least one clamping member 3 is slidably connected to the base 1, and the clamping members 3 can move toward or away from each other along the length direction of the continuous beam 2 to drive the continuous beam 2 to produce buckling deformation. For example, Figure 1 As shown, a pair of clamping members 3 are both slidably connected to the base 1. A slide groove 13 is provided on the base 1, and the slide groove 13 is arranged along the length direction of the continuous beam 2. The clamping members 3 are slidably arranged in the slide groove 13, so that a pair of clamping members 3 can move toward each other or move away from each other. Alternatively, one of the clamping members 3 is slidably arranged on the base 1, and the other clamping member 3 is fixedly arranged on the base 1. In this way, through the relative sliding of the clamping members 3 along the length direction, the continuous beam 2 can be compressed to produce buckling deformation, thereby changing the cross-sectional shape of the continuous beam 2, and then pressure can be generated on the user's skin to form a tactile display. It can be understood that the compression amount of the continuous beam 2 needs to be specifically determined according to actual design requirements.

[0054] The first driver 4 is used to drive a pair of clamping members 3 to move. For example, the first driver 4 can use a linear motor. The linear motor is connected to the clamping member 3 to drive the clamping member 3 to make reciprocating linear motion along the length direction of the continuous beam 2, thereby compressing the continuous beam 2 and causing the beam to bend and deform. For example, a pair of clamping members 3 are both slidably arranged, and the two can be independently controlled and driven by their respective corresponding linear motors. Of course, in other embodiments, the first driver 4 is not limited to the above-mentioned linear motors, and other linear drive mechanisms such as hydraulic cylinders and electric cylinders can also be used, or the clamping member 3 can be driven to make linear motion by a circular drive mechanism via a transmission mechanism. It should be noted that, in the case of Figure 1 As for the placement position of the skeleton-type continuous enhanced tactile display interface shown in the figure, the direction indicated by the solid arrow in the figure is the length direction of the continuous beam 2.

[0055] In this way, based on the interpolation characteristics of the beam under the point displacement load and the continuous movement during buckling deformation, a skeleton-type continuity-enhanced tactile interface is formed by using the continuous beam as the main output component, which can produce continuous tactile sensations on the surface of human skin, thereby interpolating and compensating for the tactile information lost between different pixels, and expanding the tactile display area from independent pixels to the lines between these pixels without increasing the pixel density, effectively enhancing the continuity of tactile display information, with a simple structure and relatively low cost. In addition, the natural continuity of the beam skeleton can also ensure that there are no sharp edges when it is raised, which plays a role in protecting the human body and improving safety in use.

[0056] In an optional embodiment of the present invention, the material of the continuous beam 2 is metal. Specifically, the material of the beam can be stainless steel, for example, 301 stainless steel. This ensures that the continuous beam 2 has a certain strength and toughness to meet its use requirements and can also increase the service life of the tactile display interface. In addition, in actual applications, a thin stainless steel beam can be used, for example, its thickness does not exceed 1 mm. In this way, it can be ensured that the continuous beam 2 will not collapse when it is compressed and deformed and comes into contact with the human body, and at the same time, the length of the continuous beam 2 will not change significantly due to axial compression. It can be understood that the thickness of the continuous beam 2 needs to be specifically determined according to actual design requirements. It should be noted that, with the following example Figure 1 For the placement of the skeleton-type continuous enhanced tactile display interface shown in the figure, the direction indicated by the hollow arrow in the figure is the thickness direction of the continuous beam 2. Of course, in other embodiments, the material of the continuous beam 2 is not limited to metal, and other thin materials with high strength and toughness can also be selected.

[0057] In a first embodiment of the present invention, Figure 1 As shown, the skeleton type continuous enhanced tactile display interface includes a base 1 and a beam unit, and also includes a plurality of moving parts 5, a plurality of first restraining parts 7, a second driver 8 and a support seat 9. Specifically, as Figure 1 As shown, each moving member 5 is spaced apart along the length direction of the continuous beam 2. The base 1 is provided with a plurality of through holes 6 adapted to each moving member 5, and the moving member 5 passes through the through holes 6 and abuts against the continuous beam 2. The moving member 5 is slidably connected to the base 1, and the moving member 5 moves along the thickness direction of the continuous beam 2. In this way, Figures 1 to 6 As shown, by controlling the longitudinal displacement of each moving member 5, the continuous beam 2 can present different shape changes according to actual design requirements, simulating the tactile sensation of a user touching an object in a scene.

[0058] Each first restraint member 7 is arranged at a position where each moving member 5 contacts the continuous beam 2. The first restraint member 7 is used to prevent the continuous beam 2 from being separated from the moving member 5, and the continuous beam 2 is slidably connected to the first restraint member 7. In other words, the first restraint member 7 limits the longitudinal displacement of the continuous beam 2 relative to the moving member 5, that is, at the contact position, the two move up and down synchronously, while allowing the continuous beam 2 to move along its length direction, so that the displacement of the pixel point can be reliably fed back, meeting the requirement of the change of the axial cross-sectional shape of the continuous beam 2.

[0059] The second driver 8 is used to drive each moving member 5 to move, so that the displacement of each moving member 5 can be controlled by the second driver 8 to meet the displacement change requirements of different pixel points. Specifically, the second driver 8 can be multiple, and each of the moving members 5 is set in a one-to-one correspondence, so as to facilitate the control of each moving member 5. The second driver 8 can use a servo motor, which is connected to the moving member 5 by transmission, for example, by gear transmission, screw transmission, etc., to convert the rotational motion of the motor into the linear reciprocating motion of the moving member 5.

[0060] The support base 9 is connected to the base 1, and the support base 9 is provided with a receiving space for accommodating the second driver 8 and each moving member 5, so as to provide an installation space for the longitudinal displacement drive unit, meet the displacement requirements of the moving member 5, and provide reliable support. Figure 1 As for the placement position of the skeleton-type continuous enhanced tactile display interface shown, the direction indicated by the solid arrow in the figure is the axial direction, the length direction of the continuous beam 2, and the direction indicated by the hollow arrow in the figure is the longitudinal direction, the thickness direction of the continuous beam 2.

[0061] In this way, a one-dimensional continuity enhanced tactile display interface is constructed, with the continuous beam 2 as the skeleton part that supports the human skin, and the deformation characteristics of the continuous beam 2 are used to improve the tactile display, significantly enhancing the display effect during the movement of the contact point. The continuous beam 2 is compressed by the first driver 4 and the clamping member 3 at both ends of the beam, and the cross-sectional shape of the continuous beam 2 is controlled by the second driver 8 and the moving member 5 in the middle, fully ensuring its shape stability and reliably reproducing the touch of objects in the virtual scene. It should be noted that the structure of the support seat 9, etc. in the figure is not specifically limited here, and is only used for display. Its specific setting can be determined according to actual design requirements.

[0062] In a second embodiment of the present invention, Figure 7 and Figure 8 As shown, it is based on the one-dimensional interface in the first embodiment and is extended to a two-dimensional interface. Specifically, the number of beam units is multiple, wherein each continuous beam 2 is cross-arranged to form a first beam grid structure. Figure 7 As shown, the first beam grid structure has a plurality of first intersections 10, and the positions of the first intersections 10 are correspondingly provided with moving parts 5 and first restraining parts 7. Accordingly, the support seat 9 is arranged below the base 1 to provide installation space. In this way, a two-dimensional beam network structure is constructed, which can fit the deformation of the two-dimensional curved surface, thereby better producing a sense of touch on the user's skin.

[0063] In a specific embodiment of the present invention, at the position of the first intersection 10, at least two continuous beams 2 are intersecting and arranged, and the number of the first restraining member 7 is at least one. Figure 7As shown, at each first intersection 10, there are three continuous beams 2 overlapping each other. The number of first restraining members 7 can be three, and each first restraining member 7 is arranged crosswise in sequence to restrain the continuous beam 2 on the moving member 5, thereby improving the reliability of use. The first restraining member 7 can be made of high-strength wire, such as commonly used fishing line, to ensure that it is not easy to break and does not affect the tactile presentation. Fig. 9 As shown, both ends of the first restraining member 7 can be fixedly connected to the moving member 5 to restrain the continuous beam 2 on the moving member 5 .

[0064] In a third embodiment of the present invention, Fig.10 As shown, it is based on the plane form in the first embodiment and is extended to the curved surface form. Specifically, the base 1 and the support seat 9 are correspondingly set to an arc structure. Since the surface of the human body is mostly curved, this arrangement makes the overall layout more reasonable and can fully fit the curve of the human body structure to adapt to the shape of the human body surface for tactile display. It should be noted that, as shown in FIG. Fig.10 As for the placement of the skeleton-type continuous enhanced tactile display interface shown, the direction indicated by the solid arrow in the figure is the length direction of the continuous beam 2, and the direction indicated by the hollow arrow in the figure is the thickness direction of the continuous beam 2.

[0065] In a fourth embodiment of the present invention, Fig.11 As shown, the difference from the second embodiment is that there is no longitudinal displacement driving unit under the base 1, that is, no second driver 8, moving member 5 and support seat 9 for controlling the lifting movement are provided. Specifically, there are multiple beam units, wherein each continuous beam 2 is cross-arranged to form a second beam grid structure. Fig.11 As shown, the second beam grid structure has a plurality of second intersections 11, and second restraints are provided at the positions of the second intersections 11. The second restraints are used to prevent the cross-arranged continuous beams 2 from being separated from each other, and the continuous beams 2 are slidably connected to the second restraints, thereby preventing the overlapped continuous beams 2 from being separated from each other, and allowing the position of each continuous beam 2 to be fine-tuned along its length direction, so as to ensure the flexible deformation capability of the grid structure.

[0066] So set up, such as Fig.14 As shown, the continuous beam 2 is compressed by the first driver 4 and the pressing member 3 at both ends of each beam, so that the continuous beam 2 bulges, and the bulge position of the grid structure is controlled by relying on the mutual cooperation between different continuous beams 2, and its continuity enhancement effect is not affected. Since the lower longitudinal displacement drive unit is eliminated, the overall thickness of the tactile display is greatly reduced, and the ratio of the bulge stroke to the display thickness when the display pressure is displayed can be greatly improved, achieving a stroke / thickness ratio far greater than 1, so that it can be covered on the human body as a wearable device, reducing the thickness of the wearable device under the same display requirements.

[0067] In a specific embodiment of the present invention, at the position of the second intersection 11, at least two continuous beams 2 are intersecting and arranged, and the number of the second restraining member is at least one. Fig.11 As shown, at each second intersection 11, there are three continuous beams 2 overlapping each other. The number of second restraints can be three, and each second restraint is arranged crosswise in sequence to restrain the continuous beam 2 on the moving member 5. The second restraint can be made of high-strength wire to ensure its reliable use and not affect the tactile display. In addition, the second restraint can be set as an annular restraint belt, so that it is convenient to install at the intersection, reliably ensuring that the overlapping beams will not detach from each other and synchronously displace longitudinally at the intersection.

[0068] As an optional embodiment of the present invention, Fig.11 As shown, the base 1 is configured as an annular base, and the two ends of each continuous beam 2 are respectively connected to the annular base. In addition, the annular base can be configured as a foldable structure to meet the requirements of display installation, etc. Further, the skeleton-type continuous enhanced tactile display interface also includes a support member 12, which is arranged in the hollow position of the annular base, and the support member 12 is located below each continuous beam 2. In this way, the support member 12 can improve the movement reliability of each continuous beam 2, so that each continuous beam 2 moves to the same side of the base 1, preventing reverse bending deformation, so as not to affect the tactile display.

[0069] In a specific embodiment of the present invention, Fig.12 As shown, the support member 12 is configured as a support plate. The support plate can be a thin plate, which covers the hollow position of the annular base to play a supporting and limiting role. Fig.13 As shown, the support member 12 is configured as a support net. The shape of the support net can be consistent with the shape of the beam grid, thereby reducing the weight of the display and being able to effectively support and constrain each continuous beam 2.

[0070] In a fifth embodiment of the present invention, Fig.15 As shown, the difference from the fourth embodiment is that the base 1 includes a first annular base 101 and a second annular base 102 arranged at intervals, and one end of each continuous beam 2 is arranged on the first annular base 101 and the other end is arranged on the second annular base 102. Specifically, the number of beam units is multiple, and each continuous beam 2 is arranged crosswise to form a second beam grid structure. Fig.16As shown, the second beam grid structure has a plurality of second intersections 11, and a second constraint is provided at the position of the second intersection 11. The second constraint is used to prevent the cross-arranged continuous beams 2 from separating from each other, and the continuous beam 2 is slidably connected to the second constraint, so as to prevent the overlapping continuous beams 2 from separating from each other, limit their protruding directions, and allow each continuous beam 2 to be fine-tuned along its length. A clamping member 3 and a first driver 4 are provided at both ends of the continuous beam 2, respectively, and the clamping member 3 and the first driver 4 are correspondingly arranged on the annular base at both ends. In this way, a cylindrical wearable device is formed, which can be put on the human body, for example, on the limbs and other parts of the human body, and is flexible to wear and easy to use. It can be understood that in this embodiment, a support net or a support plate can also be added as in the fourth embodiment.

[0071] In summary, the embodiments of the present invention provide a skeleton-type continuity-enhanced tactile display interface, which is suitable for virtual tactile interaction scenarios. Without increasing the pixel density, by adding beam units to the contact interface and utilizing their interpolation characteristics, the longitudinal movement of scattered pixel points can be converted into pressure touch sensations that continuously move along the skin surface. The tactile display interface can be expanded from a one-dimensional structure to a two-dimensional structure and a curved surface form, and can form a network skeleton structure composed of multiple continuous beams overlapped with each other. The overlaps between the beams are connected by a constraint device that allows the beams to move in their length direction. The tactile display interface can be used in conjunction with other pixel-type tactile devices to create continuous motion on the tactile interaction surface, which can enhance the continuity of the displayed tactile information during motion, and complement the missing tactile information between pixels through the natural interpolation-like characteristics of the beams, thereby improving the mobile display effect on a plane or curved surface. The tactile display interface can also be used independently as a tactile display mechanism to create continuous tactile sensations on the skin surface. In this case, it is not necessary to set up a longitudinal displacement drive unit. By relying on the constraints between different beams and independently controlling the compression of different beams, the shape and position of the grid protrusions can be controlled. It can be used as a wearable device to cover the human body, greatly reducing the thickness of wearable devices under the same display requirements. It has a simple structure, relatively low cost, easy to miniaturize, high structural strength, long service life, can significantly reduce position distortion and shape distortion, and effectively improve the motion continuity between pixels. The inherent smooth bending deformation of the beam ensures the safety of interaction, improves the user's interactive experience in virtual reality, and has good application prospects.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
