Embodiment 1

[0032] Such as figure 1 As shown, a fluid pressure tactile feedback device provided by Embodiment 1 of the present invention includes a first feedback chamber 1 , a second feedback chamber 2 , a piston assembly, a support chamber 3 , and a tactile medium 4 .

[0033] Wherein, the first feedback cavity 1 has a flexible outer wall and is filled with a first feedback fluid;

[0034] The second feedback cavity 2 is wrapped inside the first feedback cavity, which has a flexible outer wall and is filled with a second feedback fluid;

[0035] The tactile medium 4 is a plurality of granular objects, which are arranged in the first feedback cavity 1 and simultaneously located in the second feedback cavity 2; during specific implementation, the granular objects can be balls, sand grains, plastic balls, peanuts, etc. m and so on.

[0036] The piston assembly includes a third chamber 5, a piston 6 disposed inside the third chamber 5, and a connecting rod 7 that pushes the piston 6 to mo...

Embodiment 2

[0055] Such as figure 2As shown, it is a fluid pressure tactile feedback device provided in Embodiment 2 of the present invention. In this embodiment, the tactile medium 4 is also a plurality of granular objects 8, which are arranged in the first feedback cavity 1 and located in the second Outside of feedback chamber 2. Specifically, the second feedback chamber 2 is an annular chamber, and a tray 9 is fixed on the annular chamber, and the tray 9 is provided with grooves matching the shape and number of the tactile medium 4, so The tactile medium 4 is also connected with a wire rope 10, and the wire rope 10 passes through the tray 9 and is fixed on the bottom plate 11 of the first feedback chamber 1. In addition, in this embodiment, between the second feedback chamber 2 and the third chamber A valve S5 is also provided between 5 for controlling the flow of fluid between the second feedback chamber 2 and the third chamber 5 .

[0056] The following will combine figure 2 To ...

Abstract

A fluid pressure type haptic feedback device includes a first feedback chamber having a flexible outer wall and filled with a first feedback fluid; a second feedback chamber disposed inside the firstfeedback chamber, having a flexible outer wall and filled with a second feedback fluid; a haptic medium is provided in the first feedback chamber for providing a haptic simulation. The fluid pressuretype haptic feedback device of the invention can have various haptic effects including granular haptic and rough haptic, and has a simple structure, low cost and good safety, and can be used for haptic feedback of all human-computer interaction scenes, and is suitable for wide promotion.

Description

technical field [0001] The invention relates to the technical field of tactile feedback of human-computer interaction equipment, in particular to a fluid pressure tactile feedback device. Background technique [0002] In AR and VR devices, the force feedback system can provide basic tactile simulations such as gripping, while the tactile feedback component can provide more detailed simulated tactile sensations. In the prior art, there are various devices for force feedback , such as: the exoskeleton glove (Dexmo) developed by DextaRobotics, the fingertip tactile simulation device (TactaiTouch) developed by Tactai, the strap-type tactile feedback device (Impacto ), etc., but these products all have the following disadvantages: [0003] 1. The tactile sensation that can be simulated is relatively simple; [0004] 2. Heavy weight; [0005] 3. Huge and inconvenient to use; [0006] 4. The cost is high and it is difficult to promote. [0007] Therefore, prior art needs to be...
