[0030] At present, game device manufacturers increase force feedback devices in game handles to simulate the immediacy of specific game scenes, such as the force feedback game operations of archery, trigger pulling of various firearms, etc.

[0031] However, the existing force feedback device has complex structure and large volume, and cannot freely adjust the force feedback state and feedback strength, has small adjustment freedom, and cannot meet the increasing game experience demand of users.

[0032] The application provides a force feedback device, and reference is made to FIG. 1 to FIG. 4. The force feedback device is an embodiment of the application, and will be described in detail below in combination with specific drawings.

[0033] Reference is made to FIG. 1 to FIG. 4. The force feedback device 100 comprises a shell 1, a pressing rod 2 and a driving assembly 3. The shell 1 is internally provided with a thread. The pressing rod 2 extends along a first direction, one end of the pressing rod 2 extends into the shell 1 and is threadedly connected with the shell 1, so that the pressing rod 2 can move along the first direction when the pressing rod 2 rotates relative to the shell 1. The driving assembly 3 is installed on the shell 1 and is drivingly connected with the pressing rod 2. The driving assembly 3 can drive the pressing rod 2 to rotate in opposite directions.

[0034] The technical scheme of the present application, the compression rod 2 and the shell 1 are threadedly connected, so that the size of the compression rod 2 extending out of the shell 1 can be adjusted, and the driving assembly 3 is drivingly connected with the compression rod 2, and the driving assembly 3 can drive the compression rod 2 to rotate, so that the driving assembly 3 has two working processes, in one working process, the driving assembly 3 can drive the compression rod 2 to rotate, so as to adjust the size of the compression rod 2 extending out of the shell 1, and then control the compression rod 2 to abut against or separate from the trigger 200, so as to control whether the force feedback device 100 is used. When the force feedback device 100 is controlled to be used in the above working process, that is, the compression rod 2 abuts against the trigger 200, the driving assembly 3 has another working process, specifically, when the driving assembly 3 is energized to drive the compression rod 2 to extend out of the shell 1, if the trigger 200 is pressed by the user, the driving assembly 3 gives the user a blocking force in the opposite direction of pressing, combined with the friction force when the compression rod 2 rotates relative to the shell, to form force feedback to the user, and the driving assembly 3 is used to increase the feedback force; on the contrary, when the driving assembly 3 is energized to drive the compression rod 2 to retract into the shell 1, if the trigger 200 is pressed by the user, the driving assembly 3 gives the user a driving force in the same direction of pressing, to offset the friction force when the compression rod 2 rotates relative to the shell, to form force feedback to the user, and the driving assembly 3 is used to reduce the feedback force; when the driving assembly 3 is not enabled, if the user presses the trigger 200, the friction force between the compression rod 2 and the shell 1 is used as the force feedback to the user. The force feedback device 100 has the advantages of simple structure, small size, low cost, and can realize the control of the opening and closing of the force feedback device 100 and the adjustment of at least three force feedback gears of the force feedback device 100, the adjustment is relatively free, and can meet the increasing game experience demand of users.

[0035] Specifically, the driving assembly 3 comprises a transmission member 31 and a driving member 33, the driving member 33 is in transmission connection with the transmission member 31 through a transmission assembly 32 to drive the transmission member 31 to rotate forward and backward, the transmission member 31 is sleeved on the periphery of the pressing rod 2 and is used to drive the pressing rod 2 to rotate forward and backward. The driving assembly 3 can be directly drivingly connected with the pressing rod 2, but based on the working process of the driving assembly 3 described above, in addition to adjusting the feedback force of the force feedback device 100 by energization, it also needs to not affect the feedback force of the force feedback device 100 in the unenergized state. Obviously, it is difficult to achieve the activity of the pressing rod 2 without affecting the activity of the pressing rod 2 when the driving assembly 3 is directly drivingly connected with the pressing rod 2. Therefore, the driving assembly 3 is arranged to be in transmission connection with the pressing rod 2 by the transmission member 31 and the transmission assembly 32 in the application, so as to avoid the direct connection between the driving member 33 and the pressing rod 2, thereby avoiding the above problems. Meanwhile, the transmission member 31 and the transmission assembly 32 can be freely arranged to facilitate the arrangement of the driving assembly 3 in the handle 1000, thereby facilitating the space structure design.

[0036] Further, the pressing rod 2 and the transmission member 31 are slidingly arranged and rotationally fixed in the first direction. When the pressing rod 2 is rotated by the transmission member 31, the pressing rod 2 also moves in the first direction. If the driving points of the transmission member 31 and the pressing rod 2 are relatively fixed in the first direction, at least the transmission member 31 needs to move in the first direction synchronously with the pressing rod 2, that is, the transmission member 31 and the transmission assembly 32 can be slidingly arranged and rotationally fixed in the first direction, or the transmission member 31, the transmission assembly 32 and the driving member 33 can all move in the first direction together with the pressing rod 2. Obviously, such arrangement is complicated, occupies a large space and is not practical. Therefore, in the embodiment, the transmission member 31 is arranged to be slidingly arranged and rotationally fixed with the pressing rod 2 in the first direction, so that the overall position of the driving assembly 3 can be fixed to facilitate the space structure arrangement of the handle 1000.

[0037] Specifically, the periphery of the pressing rod 2 is provided with a guide groove 21 extending in the first direction, and a limiting rib 311 is protruded on the transmission member 31 and arranged to extend into the guide groove 21. In this way, the limiting rib 311 extending into the guide groove 21 can move along the guide groove 21, so that when the driving member 33 drives the transmission member 31 to rotate, the limiting rib 311 abuts against the groove wall of the guide groove 21 to drive the pressing rod 2 to rotate. On the contrary, when the pressing rod 2 rotates, it moves in the first direction relative to the housing 1. The limiting rib 311 can move along the guide groove 21 without moving the transmission member 31, thereby solving the above problems. The structure is simple, ingenious and practical.

[0038] In addition, the transmission member 31 comprises a first gear 31a. The specific structure of the transmission member 31 can be various, including but not limited to transmission belts, gears, etc. In the embodiment, the transmission member 31 is provided as the first gear 31a, which is stable in structure and low in processing cost.

[0039] In addition, the transmission assembly 32 comprises a second gear 32a mounted on the driving end of the driving member 33, and the first gear 31a is engaged with the second gear 32a. The transmission assembly 32 is mainly used for driving connection of the transmission member 31 and the driving member 33, that is, the transmission assembly 32 can be combined in various transmission modes to meet different transmission function requirements, such as remote transmission, transmission direction adjustment, etc. In the embodiment, the structure of the driving assembly 3 should be as simple as possible and the size should be as small as possible in combination with the size of the handle 1000 and the purpose of simplifying the structure and reducing the volume of the application. Therefore, the transmission assembly 32 is provided as a single transmission member 31, and the transmission structure connected with the first gear 31a can also be various, including but not limited to transmission belts, gears, etc. In the embodiment, the transmission assembly 32 is provided as the second gear 32a, which meets the structural function requirement, has strong structural stability, is low in cost and good in effect.

[0040] In addition, the housing 1 is also provided with a position detection device 4 for detecting the position of the pressing rod 2 relative to the housing 1 in the first direction. In order to accurately control the force feedback device 100, that is, to obtain the position of the pressing rod 2 in the housing 1 in real time, the driving state of the driving assembly 3 is adjusted in real time, and then more abundant resistance output is provided to meet the force feedback requirement of the force feedback device 100. The position detection device 4 is also provided on the housing 1 to detect the position of the pressing rod 2 relative to the housing 1.

[0041] Specifically, the position detection device 4 comprises a magnetic inductor 41 provided on the housing 1, and a magnet 5 is correspondingly provided on the pressing rod 2. The position detection device 4 can be various, including but not limited to physical contact type position detection device 4, visual detection device, infrared distance sensor, etc. In the embodiment, the combination of the magnetic inductor 41 and the magnet 5 is mainly adopted, which is difficult to be blocked and interfered, and has stronger practicability.

[0042] Specifically, the magnetic sensor 41 is arranged outside the shell 1; the magnet 5 is arranged inside the pressing rod 2. Since the magnetic induction detection mode between the magnetic sensor 41 and the magnet 5 can be detected through the object, the magnetic sensor 41 can be arranged outside the shell 1, which reduces the volume of the force feedback device 100 on the one hand, and facilitates the maintenance and replacement of the magnetic sensor 41 on the other hand. The magnet 5 arranged on the pressing rod 2 is arranged inside the pressing rod 2, specifically, at the rotation center of the pressing rod 2, so as to avoid the distance change between the magnet 5 and the magnetic sensor 41 due to the rotation of the pressing rod 2 in the rotation process of the pressing rod 2, and to avoid that the distance change makes the magnetic sensor 41 misjudge the distance between them in the first direction, thereby avoiding affecting the position detection precision of the combination of the magnetic sensor 41 and the magnet 5.

[0043] The application further provides a handle 1000, which comprises a trigger 200 and the force feedback device 100. The specific structure of the force feedback device 100 is referred to the above-mentioned embodiments. Since the handle 1000 adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0044] The above-mentioned is only an exemplary embodiment of the application, and does not limit the patent scope of the application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, which is made under the technical concept of the application, by using the content of the specification and drawings of the application, is included in the patent protection scope of the application.
