Multi-motor handle

Abstract

According to the multi-motor handle, a user holds the handle body and operates the control end at the same time. The control system determines which vibration motor is activated or activates the two motors at the same time according to input signals (such as operation actions of a user and feedback information of a virtual reality scene). If the operation or scene of the user needs to simulate finer tactile feedback (such as the vibration difference of the left and right hands or the vibration sense of hand actions), the control system can adjust the vibration frequency or intensity of the first vibration motor and the second vibration motor respectively so as to provide a more vivid immersion experience. When the first vibration motor and / or the second vibration motor are / is activated, the first vibration motor and / or the second vibration motor vibrate at the holding end and the control end respectively, so that a user can feel vibration feedback at different parts (palms and fingers), and further more three-dimensional and real touch feeling is generated.

Description

Technical Field

[0001] The present application relates to the field of VR, and in particular to a multi-motor handle. Background Art

[0002] Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world. It uses a VR headset to create an immersive experience that includes 3D visuals, sound, and sometimes haptic feedback. This technology is commonly used in gaming, training, education, therapy, design, and social experiences.

[0003] VR controllers, hardware devices that control virtual reality content through buttons and joysticks, have gradually matured. They come in a variety of styles, including 6DOF controllers for all-in-one VR headsets or PC-based VR headsets, and simple, low-profile 3DOF controllers for use with mobile phones. With the rapid advancement of smart electronic devices, users are demanding an increasingly sophisticated user experience from VR controllers.

[0004] To enhance the user experience, most VR controllers are equipped with force feedback devices and offer a variety of force feedback modes. These modes enhance the interaction between VR content and players, simulating realistic tactile feedback. However, some controllers currently on the market only use a single motor vibration as force feedback, resulting in a limited feedback effect and a lack of a rich user experience, making them inconvenient for users.

[0044] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0045] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0046] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0047] An embodiment of the present application provides a multi-motor handle 100, comprising:

[0048] The handle body 110 has a gripping end 111 and a control end 112 , and the gripping end 111 and the control end 112 are respectively located at two ends of the handle body 110 ;

[0049] A first vibration motor 120 is provided at the gripping end 111;

[0050] A second vibration motor 130 is provided at the control end 112;

[0051] The control system 140 is provided on the handle body 110 , and the control system 140 is electrically connected to the first vibration motor 120 and the second vibration motor 130 .

[0052] Please refer to Figure 1-Figure 5 In this embodiment, the user holds the handle body 110 and operates the control end 112 at the same time.

[0053] The control system 140 decides which vibration motor to activate, or activates both motors at the same time, based on input signals (such as user operation actions, feedback information of the virtual reality scene, etc.).

[0054] If the user's operation or scenario requires simulation of more refined tactile feedback (such as the difference in vibration between the left and right hands or the vibration of hand movements), the control system 140 can adjust the vibration frequency or intensity of the first and second vibration motors 130 respectively to provide a more realistic immersive experience.

[0055] When the first vibration motor 120 and / or the second vibration motor 130 are activated, they vibrate at the gripping end 111 and the control end 112 respectively, allowing the user to feel vibration feedback at different parts of the body (palm and fingers), thereby producing a more three-dimensional and realistic tactile experience.

[0056] The multi-motor design allows users to experience vibration feedback in different areas of the multi-motor handle 100 (the grip end 111 and the control end 112), effectively enhancing the user's immersive and interactive experience. Users can experience real-time interaction with virtual reality content, as if they were actually there.

[0057] By regulating multiple motors through the control system 140, a variety of vibration modes (such as synchronous vibration, alternating vibration, and varying intensities) can be achieved, thereby providing richer and more diverse tactile feedback effects. Compared to traditional single-motor designs, the multi-motor structure makes the multi-motor handle 100 more responsive and can more accurately simulate the tactile experience in real scenes.

[0058] It should be noted that the gripping end 111 is roughly cylindrical, and a conical limiting portion 1112 is provided at the end away from the control end 112. The side surface of the limiting portion 1112 is concave inward to form an arc surface to fit the end of the hand to prevent the handle body 110 from detaching during use.

[0059] The control end 112 is substantially T-shaped, and one end of the control end 112 away from the grip end 111 is a ring-shaped portion 1121 .

[0060] The first vibration motor 120 and the second vibration motor 130 are both motors that can generate vibrations.

[0061] In at least one embodiment of the present application, the distance from the first vibration motor 120 to the second vibration motor 130 is denoted as a, which satisfies the relationship: 10 cm ≤ a ≤ 14 cm.

[0062] Please refer to Figure 1-Figure 5 In this embodiment, the distance (a) from the first vibration motor 120 to the second vibration motor 130 is installed on the handle body 110, and is the straight-line distance between the first vibration motor 120 located at the grip end 111 and the second vibration motor 130 located at the control end 112.

[0063] The distance range (10cm≤a≤14cm) is intended to optimize the tactile feedback experience of the multi-motor handle 100, so that the vibrations generated by the two motors can cover different areas of the multi-motor handle 100, so that the user can fully feel the vibration effects of different parts when using it.

[0064] Ergonomics and the actual size of the multi-motor handle 100 are taken into consideration so that it not only conforms to the user's gripping habits but also provides uniform vibration distribution throughout the multi-motor handle 100 .

[0065] This ensures that the multi-motor handle 100 can obtain effective vibration feedback in both the palm holding and finger operation areas, thereby maximizing the effectiveness of the vibration motor.

[0066] In at least one embodiment of the present application, the relationship is satisfied: 11 cm ≤ a ≤ 13 cm.

[0067] Please refer to Figure 1-Figure 5 In this embodiment, the relationship is satisfied: 11cm≤a≤13cm, ensuring that the two vibration motors can provide the best tactile feedback experience at different parts of the multi-motor handle 100 (i.e., the areas operated by the user's palms and fingers).

[0068] It ensures that users can obtain uniform and real vibration feedback in every usage scenario, and can also achieve more delicate and precise tactile effects through the coordinated work between motors.

[0069] By narrowing the distance range to between 11cm and 13cm, the feedback effect between the two vibration motors is more accurately covered, avoiding tactile deviations caused by excessive or insufficient distances. This ensures that users receive the best vibration experience during use and improves the responsiveness of the multi-motor handle 100 in different operating scenarios.

[0070] The precisely defined distance range allows the multi-motor handle 100 to provide more coordinated vibration feedback across different areas. The control system 140 can precisely control the synchronous or asynchronous vibrations of the vibration motors within this distance, thereby simulating a more realistic tactile experience for the user. For example, when simulating grip or pressure sensing, adjusting the vibration frequency difference between the two motors can achieve a more layered tactile feedback.

[0071] In at least one embodiment of the present application, a receiving cavity is formed inside the handle body 110 , and the first vibration motor 120 and the second vibration motor 130 are both disposed in the receiving cavity.

[0072] Please refer to Figure 1-Figure 5 In this embodiment, a receiving cavity (not shown in the figure) is provided inside the handle body 110 to provide a specific space for installing and fixing internal components, including the first vibration motor 120, the second vibration motor 130 and other electronic components.

[0073] The presence of the accommodating cavity helps to rationally arrange all necessary components inside the multi-motor handle 100, making its structure compact while protecting these components from external impact or interference.

[0074] Placing the first vibration motor 120 and the second vibration motor 130 in the same accommodating cavity can ensure that the position of the vibration source is relatively fixed, so that the vibration signal can be effectively transmitted from the inside of the multi-motor handle 100 to various areas on the surface of the multi-motor handle 100, thereby achieving a more uniform vibration effect.

[0075] It should be noted that the accommodating cavity has a sealed cavity structure.

[0076] In at least one embodiment of the present application, the control end 112 is provided with an annular portion 1121;

[0077] The multi-motor handle 100 further includes:

[0078] The sensor 150 is disposed on the annular portion 1121 .

[0079] Please refer to Figure 1-Figure 5 In this embodiment, when the user holds the multi-motor handle 100 and operates it, the user's fingers will naturally contact or approach the annular portion 1121 of the control end 112.

[0080] The sensor 150 obtains user input signals by detecting the user's finger movements (such as pressing, sliding or gestures). These signals can be feedback of pressure, touch or other gestures.

[0081] The sensor 150 transmits the detected data to the control system 140 , and the control system 140 determines how to activate the vibration motor or perform other feedback actions in response to the user's operation.

[0082] Since the sensor 150 is arranged on the annular portion 1121, it can be ensured that it is always within the range of finger operation, thereby achieving accurate and efficient data collection and interactive effects.

[0083] Providing a ring portion 1121 on the control end 112 and placing the sensor 150 on the ring portion 1121 ensures that the sensor 150 is located in the area where the user's fingers frequently operate. This allows the sensor 150 to accurately capture the user's operational details (such as pressing force, sliding speed, or specific gestures), thereby significantly improving the operational sensitivity and accuracy of the multi-motor controller 100. This is particularly useful for enhancing fine-tuned operations (such as shooting, picking up, or sliding) in virtual reality experiences.

[0084] Placing sensor 150 on the ring portion 1121, where the user's fingers frequently operate, allows for faster acquisition of user operation signals and transmission to control system 140. This allows control system 140 to react more quickly, activating the vibration motor or other feedback device in multi-motor controller 100. The optimized placement of sensor 150 effectively improves the response speed of multi-motor controller 100, making its feedback in a virtual reality environment more immediate and accurate.

[0085] It should be noted that the sensor 150 can be provided on the holding end 111 , and the sensor 150 is used to capture the user's behavior to provide accuracy of interaction.

[0086] In at least one embodiment of the present application, the control end 112 is further provided with a control portion 1122 , and the control portion 1122 is located on a side close to the annular portion 1121 ;

[0087] The multi-motor handle 100 further includes:

[0088] The first control button 160 is disposed in the control unit 1122 and is electrically connected to the control system 140 .

[0089] In at least one embodiment of the present application, the multi-motor handle 100 further includes:

[0090] The second control button 170 is disposed at the junction of the control unit 1122 and the gripping end 111 and is electrically connected to the control system 140 .

[0091] Please refer to Figure 1-Figure 5 In this embodiment, the control portion 1122 is provided with an inclined surface, which is formed by tilting from the control portion 1122 to a side away from the annular portion 1121, and the first control button 160 is provided on the inclined surface for user operation.

[0092] The second control button 170 is provided at the junction of the control portion 1122 and the grip portion 1111 so that the user can use other free fingers for control during operation. The first control button 160 and the second control button 170 provide different functions.

[0093] In at least one embodiment of the present application, the holding end 111 includes a holding portion 1111 and a limiting portion 1112, the holding portion 1111 is connected to one end of the control end 112, and the other end of the holding portion 1111 is connected to the limiting portion 1112, and the diameter of the limiting portion 1112 is greater than the maximum diameter of the holding portion 1111.

[0094] Please refer to Figure 1-Figure 5In this embodiment, the gripping end 111 is the main area where the user grips the multi-motor handle 100 and is composed of a “gripping portion 1111” and a “limiting portion 1112”.

[0095] The grip portion 1111 is the main portion where the user's palm contacts the multi-motor handle 100 , ensuring the user's comfort during long-term use and the stability of the multi-motor handle 100 .

[0096] The limiting portion 1112 is located at one end of the grip portion 1111, and its diameter is larger than the maximum diameter of the grip portion 1111. This provides a natural limit when the user grips the multi-motor handle 100, preventing the multi-motor handle 100 from slipping or falling out of the user's hand, thereby improving safety and stability in use.

[0097] The overall stability of the multi-motor handle 100 is ensured, and the stability of the multi-motor handle 100 at the grip portion 1111 is also ensured when the user operates the buttons or other functional components of the control end 112 .

[0098] The other end of the gripping portion 1111 is connected to the limiting portion 1112 , which plays a protective and supporting role, preventing the user's hand from slipping out of the gripping portion 1111 during intense operation or prolonged use.

[0099] It should be noted that the gripping portion 1111 is substantially cylindrical.

[0100] In at least one embodiment of the present application, the control system 140 includes: a processor (not shown in the figure), a circuit board (not shown in the figure) and a power supply (not shown in the figure), the processor and the power supply are electrically connected to the circuit board, and the control system 140 is arranged in the holding end 111.

[0101] Please refer to Figure 1-Figure 5 In this embodiment, the control system 140 is the core component of the entire multi-motor handle 100 and is used to control various functions and responses of the multi-motor handle 100.

[0102] It includes three main parts: the processor is responsible for executing and processing signals from the sensor 150, buttons or other input devices, and deciding how to control the output of the multi-motor handle 100 (for example, the working status of the vibration motor) based on the input.

[0103] The circuit board is used to integrate and connect the various components of the control system 140 and is the main platform for electrical signal transmission and processing. All key components (such as processors and power supplies) are interconnected through the circuit board to ensure stable operation of the system.

[0104] The power supply provides the required electrical energy to ensure that the control system 140 can continue to work. The power supply may be designed to include a rechargeable battery or other power management module to ensure that the multi-motor handle 100 has a stable power supply under different operating conditions.

[0105] The processor and power supply are connected to the circuit board separately, ensuring that all components can work together. The circuit board acts as a central platform, coordinating the signal processing tasks of the processor and the power supply tasks of the power supply, enabling efficient communication and operation between all components within the system.

[0106] The system can quickly respond to user input and convey instructions to the first vibration motor 120, the second vibration motor 130 or other functional modules of the multi-motor handle 100, ensuring the operational efficiency and response speed of the entire multi-motor handle 100.

[0107] By integrating the processor, circuit board, and power supply and placing them within the grip end 111 of the multi-motor handle 100, the overall design of the multi-motor handle 100 becomes more compact. This reduces the use of redundant components, improves the efficiency of internal space utilization, and makes the multi-motor handle 100 more aesthetically pleasing, lightweight, and easy to hold.

[0108] In at least one embodiment of the present application, the number of the first vibration motors 120 is two or more.

[0109] Please refer to Figure 1-Figure 5 In this embodiment, the coordinated operation of multiple vibration sources provides users with more three-dimensional and rich tactile feedback.

[0110] Increasing the number of vibration motors helps the multi-motor handle 100 provide more delicate and diverse feedback in different areas (such as different parts of the palm), while also providing greater flexibility for the vibration mode setting of the control system 140.

[0111] When the user holds the multi-motor handle 100 and operates it, the control system 140 activates the first vibration motor 120 or the second vibration motor 130 located at the grip end 111 based on the feedback of the virtual scene or the user's input (such as pressing a button or moving a joystick).

[0112] According to the scene requirements, different frequencies, intensities or modes (such as synchronization, alternation, variable frequency, etc.) are used for separate actions.

[0113] The arrangement of multiple first vibration motors 120 or second vibration motors 130 can cover different areas of the palm, allowing the user to feel vibrations from different angles and positions when operating the multi-motor handle 100. This multi-point feedback mechanism enhances the user's immersion and tactile refinement.

[0114] The control system 140 precisely controls the movement of each motor according to different scenarios or user operation requirements to ensure the immediacy and consistency of tactile feedback.

[0115] By increasing the number of first vibration motors 120 or second vibration motors 130, the multi-motor controller 100 can generate vibrations in multiple areas, thereby achieving more three-dimensional tactile feedback. For example, in a game or virtual reality scene, different vibration motors can generate vibrations of different frequencies or intensities based on scene changes (such as collisions, shooting, environmental changes, etc.), giving the user a more realistic and immersive experience.

[0116] The multi-motor design enables the multi-motor controller 100 to provide precise vibration feedback based on the user's operation during use. For example, in a virtual reality game, when the user holds the multi-motor controller 100, they can feel vibration feedback from different parts of the multi-motor controller 100. This distributed feedback can accurately simulate the tactile sensation of reality (such as the impact of a collision or the vibration of movement), greatly enhancing the user's sense of immersion.

[0117] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
