[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application and have no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0032] In order to solve the problems mentioned in the background technology, refer to Figure 1-Figure 4 According to one aspect of the embodiments of the present application, an embodiment of a handle tactile feedback structure is provided.

[0033] The handle tactile feedback structure provided in the embodiment of the present application includes:

[0034] at least one tactile feedback component, including a track 2 and a driving component corresponding to the track 2, wherein the driving component is arranged on the inner side of the handle, the track 2 is wrapped on the outer side of the handle, and the position where the track 2 is arranged corresponds to the position where the driving component is arranged; the movable end of the driving component is connected to the track 2 and is configured to drive the track 2 to rotate; and

[0035] The controller 3 is electrically connected to the driving component and is configured to adjust the motion parameters of the active end of the driving component.

[0036] The track 2 is wrapped around the outside of the handle, and when the user holds the handle, the track 2 on the outside of the handle is directly in contact. When the handle needs tactile feedback, the driving component drives the rotation of the track 2, allowing the user to feel the movement of the handle in his hand. In addition, in different scenarios, the motion parameters of the active end of the driving component are adjusted by the controller 3, thereby adjusting the motion parameters of the track 2, so that in different scenarios, the track 2 allows the user to feel different movements caused by the handle in his hand. Compared with the single motor vibration feedback of the existing handle, the handle provided by this application can bring a better user experience.

[0037] Reference Figure 2-Figure 4 In some embodiments, the driving component can be any component that can drive the track 2 to rotate, such as a motor, a motor, a rotating cylinder, etc. The movable end of the driving component is directly connected to the track 2 to achieve the effect of driving the track 2 to rotate.

[0038] In the present application, the driving component includes a driver 4, a first transmission member 5 and a second transmission member, the first transmission member 5 and the second transmission member are in transmission cooperation, the driver 4 is connected to the first transmission member 5, the second transmission member is connected to the crawler 2, and the driver 4 regulates the rotation of the second transmission member through the first transmission member 5; the transmission connection between the driver 4 and the crawler 2 is realized by the arrangement of the first transmission member 5 and the second transmission member. In addition, due to the arrangement of the first transmission member 5 and the second transmission member, the movable end of the driver 4 can be a component that is set to rotate or move, and under the transmission action of the first transmission member 5 and the second transmission member, the second transmission member can be driven to rotate. Of course, the first transmission member 5 and the second transmission member can also be any component that can realize transmission cooperation, such as a connecting rod structure, gear meshing, or gear rack cooperation.

[0039] Optionally, the driver 4 includes a rotator, the first transmission member 5 includes a gear, and the second transmission member includes a tooth hole 21 formed on the track 2; wherein the rotator includes a rotating motor, a rotating cylinder, etc., and the rotator in the present application adopts a rotating motor, and a gear is coaxially fixed on the output shaft of the rotating motor, and gears meshing with the gears are formed on the circumference of the inner wall of the track 2, so as to ensure that the track 2 can maintain a good meshing effect with the gear when it rotates to any position during the rotation process; therefore, the rotation of the output shaft of the rotating motor will drive the rotation of the gear, and under the meshing action of the gear and the tooth hole 21, the rotation of the gear will drive the rotation of the track 2.

[0040] In some embodiments, the motion parameters include at least the motion mode, i.e., different rotation directions of the track 2. When the user uses the handle, in different application scenarios, the driving component can drive the track 2 to rotate clockwise or counterclockwise to provide the user with different tactile feedback experiences.

[0041] In addition, the motion parameters may also include motion time or motion speed, for example, different rotation times of the crawler 2 or different rotation speeds of the crawler 2 may be used to achieve different scene simulations. It is known that in different scenes, the above different motion parameters may be used alone or in combination to achieve simulation. For example, in different scenes, any two or all of the rotation speed, duration, and rotation direction of the crawler 2 may be combined to achieve scene simulation.

[0042] Reference Figure 1 In some embodiments, the track 2 can rotate around the circumference of the handle. When the user uses the handle, taking a single right hand as an example, the four fingers of the right hand are on the right side of the handle, and the thumb of the right hand is on the left side or inside of the handle. The friction brought by the rotation of the track 2 is used to achieve tactile simulation.

[0043] Of course, the rotation direction of the track 2 can also be set at an angle with the circumferential direction of the handle, that is, the track 2 rotates relative to the tilt direction of the handpiece 1, further enhancing the friction feeling brought by the rotation of the track 2 to the user.

[0044] Reference Figure 3-Figure 4 In some embodiments, the at least one tactile feedback component is distributed along the axial direction of the handle; the friction area between the user's hand and the handle is increased by multiple groups of tactile feedback components, thereby improving the user's tactile experience during use.

[0045] Of course, when there are two or more tactile feedback components, the two adjacent tracks 2 in two adjacent groups of tactile feedback components can be arranged at intervals or adjacent to each other. When multiple tracks 2 are provided, the multiple tracks 2 can be matched with different rotation directions, rotation speeds and durations to bring more scene simulations and a wider range of applications.

[0046] In some embodiments, the motion parameters of each track 2 are the same, that is, all tracks 2 move simultaneously, in the same direction and at the same frequency. As an example, each track 2 can rotate in a clockwise direction at the same speed for the same time, thereby providing tactile feedback to the user.

[0047] Of course, the motion parameters of some of the tracks 2 may be the same, or the motion parameters of all the tracks 2 may be different. The same motion parameters of some of the tracks 2 also include the same motion parameters of any adjacent n tracks 2, and different motion parameters of the remaining tracks 2, or the same motion parameters of the non-adjacent tracks 2, etc. Therefore, the tracks 2 on the handle provided by the present application can have multiple physical quantity simulations and tactile feedback simulations, which can provide users with a rich user experience.

[0048] Reference Figure 1-Figure 4 , the following are several different usage scenarios for detailed description:

[0049] Taking a single right hand as an example, the difference is that when the right hand grasps the handle, the four fingers are on the right side of the handle, and the thumb is on the left side or inside of the handle. The direction experience brought by rotating the track 2 on the handle clockwise (i.e., rotating downward relative to the handle) or counterclockwise (i.e., rotating downward relative to the handle) is different; if it is the left hand, the example direction of the right hand needs to be reversed.

[0050] When the user picks up something in the virtual scene, the controller 3 can control each driving component to drive each track 2 to rotate upward or downward for a certain time and distance according to the same rotation time, rotation speed and rotation direction, wherein the rotation time can be a shorter time and the rotation direction can be counterclockwise, that is, when the user picks up something, each track 2 rotates upward for a shorter time and distance at the same time, allowing the user to feel the movement brought by the handle in his hand, and thus subconsciously hold the handle tightly to fix it, which can bring a sense of grip.

[0051] When the user only makes a grasping action in the virtual scene, the controller 3 can control the rotation time and rotation speed of each driving component to be the same, and the rotation direction of the active end of the driving component used to control the upper track 2 is different from the rotation direction of the active end of the driving component used to control the lower track 2. For example, the track 2 of the upper part of the control handle rotates upward, and the track 2 of the lower part of the control handle rotates downward, and rotates for a shorter time and distance, so that the user's palm can feel the friction and simulate the feeling of grasping.

[0052] When the user makes a swinging motion in the virtual scene, the controller 3 can control the active ends of each driving component to move simultaneously and at the same speed in the clockwise direction, that is, each track 2 rotates downward by a certain distance at the same time, bringing an experience of downward friction force to oppose the hand, thereby allowing the user to feel the resistance when swinging upward; by the same token, when the user swings downward, each track 2 rotates upward by a certain distance at the same time, bringing an experience of downward friction force to oppose the hand, thereby allowing the user to feel the resistance when swinging downward.

[0053] When the user performs movements such as gun shooting in a virtual scene, the controller 3 can control the high-frequency and short-distance intermittent movement of the active end of each driving component to drive the high-frequency and short-distance intermittent rotation of each track 2, so as to simulate the recoil of the gun through the short-distance, high-frequency rotation and pause of each track 2.

[0054] It can be known that the above-mentioned scenes are only examples of some scenes when the handle is used. In actual use, the rotation of the track 2 can also provide the user with tactile feedback experience in other scenes. In addition, the above-mentioned examples are only based on the use of the user's right hand. According to the symmetry of the user's left and right hands, it can be known that in order to achieve the same tactile feedback experience, the rotation direction of the track 2 of the handle adapted for the left and right hands in the same scene is opposite.

[0055] To sum up, the handle provided by the present application realizes the functions of handle physical quantity simulation and tactile feedback. The rotation of the track 2 on the handle brings the feeling of friction to the palm, thereby bringing tactile simulation; the rotation of multiple tracks 2 in different directions brings physical quantity simulation to the palm. Compared with traditional motor vibration, the present application brings friction through the rotation of the track 2, and its contact area with the palm is larger and the feeling is more obvious. The combination of multiple tracks 2 with different rotation directions, rotation speeds, and rotation times can bring more scene simulations and a wider range of applications. Moreover, its combination can also bring better simulation of the feeling of physical quantities such as resistance, inertia, and gravity.

[0056] Reference Figure 5 , an embodiment of the present application also provides a handle, which includes the handle tactile feedback structure described in the aforementioned embodiment.

[0057] The handle also includes:

[0058] A hand piece 1, wherein a receiving space is provided inside thereof;

[0059] The crawler belt 2 is rotatably disposed on the outer peripheral side of the hand piece 1, and the driving component is disposed in the accommodating space.

[0060] The handpiece 1 is used for the user to hold, and the accommodating space inside the handpiece 1 is used for placing the driving component, thereby providing a placement area and protection for the driving component. The track 2 is rotatably arranged on the outer peripheral side of the handpiece 1. When the user holds the handpiece 1, the track 2 on the handpiece 1 is directly contacted. When the handle needs tactile feedback, the driving component drives the rotation of the track 2, allowing the user to feel the movement brought by the handle in the hand.

[0061] In some embodiments, the handpiece 1 can be a structure of any shape, such as a cylindrical structure, a conical structure, or a handle-shaped structure like a recreational gun, etc., which is not limited in this embodiment.
