[0022] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.
[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0024] Figure 1 FIG. 1 shows a schematic structural diagram of an embodiment of a tactile actuator according to the present application. Figure 1 As shown, the tactile actuator 100 may include a motor, a motion block 101, a transmission device, and a housing 102. Since the transmission device and the motor are located inside the housing 102, Figure 1 The transmission and the motor are not shown.
[0025] Here, a movement slot 1021 is provided on the housing 102. The material of the housing 102 may include, but is not limited to: plastic, rubber and composite materials. The movement slot may be provided at one end of the housing 102, for example, at the position shown in the icon 1021.
[0026] Figure 2 FIG. 1 shows a schematic diagram of a structure of a motion block of a tactile actuator according to an embodiment of the present invention. Figure 2 As shown, the motion block 101 may include a motion block body 1011 and a connector 1012 passing through a motion slot 1021 . The motion block body 1011 is located outside the housing 102 and is used to contact the human body. For example, a user may place a finger on the motion block body 1011 .
[0027] like Figure 3 As shown, Figure 3 A schematic diagram of an embodiment of an application scenario of a tactile actuator according to the present application is shown, and the movement of the motion block can stretch the human skin, thereby increasing the tactile experience of the human hand.
[0028] The motion block body 1011 is usually connected to the first end of the connecting member 1012, and the second end of the connecting member 1012 is connected to the transmission device. That is, the connecting member 1012 passes through the motion slot 1021, one end is connected to the motion block body 1011, and the other end is connected to the transmission device.
[0029] The transmission device is an intermediate device that transmits the power of the power device to the working mechanism, etc. Here, the transmission device transmits the power generated by the motor to the motion block 101, thereby driving the motion block 101 to move.
[0030] The tactile actuator is usually connected to the terminal device for communication, and can receive the control signal of the terminal device, control the motor to work, and thus drive the motion block body 1011 to move through the transmission device. Here, the terminal device can be an extended reality (Extended Reality, XR) device. Since the motion block body is in contact with the human body, it can stretch the human skin and provide an immersive experience for the user.
[0031] Here, the communication connection between the motor and the XR device can be a wired connection or a wireless connection.
[0032] XR describes a series of methods to change reality. Since XR is a general term for multiple technologies such as VR (Virtual Reality), AR (Augmented Reality) and MR (Mixed Reality), XR devices generally include: VR devices, AR devices and MR devices.
[0033] It should be noted that the XR device can adjust the control signal sent to the tactile actuator according to the picture being played, so that the motor of the tactile actuator drives the motion block to move through the transmission device, thereby achieving a stretching sensation on the human skin at different rates, frequencies and displacement sizes, providing users with a better immersive experience.
[0034] Figure 4 FIG. 2 shows a schematic structural diagram of another embodiment of a tactile actuator according to the present application. Figure 4 As shown, the transmission device may be a screw module 103 , which generally includes a linear guide rail 1031 , a motion nut 1032 , a ball screw 1033 and a base 1034 .
[0035] Here, the linear guide 1031 and the ball screw 1033 are usually arranged on the base. The linear guide 1031 can be arranged on the base by laser welding. The ball screw 1033 and the base 1034 can be connected by a bearing, and the outer ring of the bearing and the base 1034 can also be connected by laser welding.
[0036] The connecting piece 1012 of the moving block is fixedly connected to the moving nut 1033, for example, by a snap or heavy double-sided tape.
[0037] The linear guide rail 1031 is used to guide the moving direction of the moving nut 1032 .
[0038] The ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotational motion into linear motion, or convert linear motion into rotational motion. It has the characteristics of high precision, reversibility and high efficiency. Due to its small friction resistance, the ball screw is widely used in various industrial equipment and precision instruments. Here, the motor 104 can control the ball screw 1033 to rotate, thereby driving the motion nut 1032 to move along the direction of the linear guide 1031 to drive the motion block body 1011 to move. Since the motion block body is in contact with the human body, it can stretch the human skin and provide an immersive experience for the user.
[0039] As an example, the linear guide rail 1031 , the motion nut 1032 , and the base 1034 may be made of stainless steel, and the motion nut 1032 may be made of a composite material.
[0040] In some optional implementations, the screw module 103 may further include a coupling, such as Figure 4 As shown in the icon 1035 in FIG. A coupling is a device that connects two shafts or a shaft and a rotating part, rotates together during the transmission of motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive loads, playing a role in overload protection. The motor 104 can be connected to the ball screw 1033 through the coupling 1035. For example, the coupling 1035 and the ball screw 1033 can be glued together.
[0041] In some optional implementations, the screw module 103 may also include a reduction box, and the ball screw 1033 may be connected to the motor 104 through the reduction box. A reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing, and is often used as a reduction transmission device between a prime mover and a working machine. It plays a role in matching the speed and transmitting torque between the prime mover and the working machine or the actuator. The reduction box is usually located between the ball screw 1033 and the motor 104.
[0042] It should be noted that the screw module 103 may also include a coupling and a reduction box at the same time.
[0043] In some optional implementations, the portion of the motion block body 1011 that contacts the human body may be made of a flexible material, such as silicone. Since the motion block body contacts the human body, the flexible material is relatively soft, thereby improving the user experience.
[0044] In some optional implementations, the screw module 103 can be fastened to the housing 102 .
[0045] In some optional implementations, the connecting piece of the moving block 101 may be fixedly connected to the moving nut 1032 .
[0046] In some optional implementations, the motor 104 may be fixedly connected to the base 1034 .
[0047] Here, the connector can be fastened or fixed by screws. Connecting by screws can make the connection tighter and easier to disassemble.
[0048] In some optional implementations, there may be two linear guide rails 1031. Using two linear guide rails can make the motion nut move more smoothly along the linear guide rails.
[0049] Figure 5 FIG. 1 is a schematic diagram showing an embodiment of an extended reality device according to the present application. Figure 5 As shown, the extended reality device 500 may include an extended reality device body 501 and a tactile actuator 502 as described in the embodiment of the present application. Figure 5 In the embodiment, the extended reality device body 501 and the tactile actuator 502 are connected via a wired connection, and in some cases, they can also be connected via a wireless connection.
[0050] The extended reality device body 501 includes a control device, and the tactile actuator 502 is connected to the control device for receiving a control signal from the control device and controlling the motor of the tactile actuator 502 to drive the motion block body to move through the transmission device. Since the motion block body is in contact with the human body, it can stretch the human skin and provide an immersive experience for the user.
[0051] It should be noted that the XR device can adjust the control signal sent to the tactile actuator according to the picture being played, so that the motor drives the motion block to move through the transmission device, achieving a stretching sensation on the human skin at different rates, frequencies and displacement sizes, providing users with a better immersive experience.
[0052] Figure 6 FIG. 1 is a schematic diagram of an embodiment of a tactile feedback device according to the present application. The tactile feedback device may include at least one tactile actuator according to an embodiment of the present application. Figure 6 In the embodiment, the tactile feedback device includes two tactile actuators, namely, tactile actuator 601 and tactile actuator 602. The user can hold the two tactile actuators with the left hand and the right hand respectively, and feel the stretching feeling brought to the skin by the two tactile actuators at the same time, which further improves the user's experience.
