Description

Technical Field

[0001] This utility model relates to the field of game controller technology, and more specifically, to a shoulder button force feedback adjustment mechanism for a game controller. Background Technology

[0002] Existing game controllers typically use a single-force adjustment mode for shoulder button down-press switches, meaning the button pressure for the left and right shoulder buttons on the same controller is essentially constant. However, different players have different tactile preferences for shoulder button down-press pressure. If all shoulder buttons have the same down-press pressure, the player experience is not user-friendly. To improve the player experience and cater to the different down-press pressure requirements of various players, this solution proposes a shoulder button down-press force feedback mechanism. This mechanism uses shoulder button down-press force feedback technology to simulate realistic physical tactile sensations and dynamic resistance changes, thereby enhancing the game controller component's immersive experience.

The shoulder button is rotatably mounted at the end of the battery bracket via a pivot and a torsion spring. The battery bracket and the force feedback adjustment mechanism are respectively fixedly mounted on the circuit board. A push rod is fixedly connected to the bottom of the shoulder button and positioned opposite to the input end of the force feedback adjustment mechanism. The force feedback adjustment mechanism is configured as a two-stage gear feedback device or a three-stage gear feedback device.

The motor is fixedly mounted on the outside of the motor mount. Several planetary gears are provided, each meshing with the gear ring of the internal gear via a planet carrier. The sun gear is driven by the output shaft of the motor and passes through the planet carrier, meshing with each planetary gear. Each planetary gear is driven by the output gear set via the planet carrier. The output gear set meshes with the swing arm gear.

[0005] Preferably, the output gear set of the two-stage gear feedback device includes an output drive gear, and the protrusions on the planetary carrier are all inserted into the first limiting holes corresponding to the first connecting side plate of the output drive gear.

[0006] Preferably, the output gear set of the three-stage gear feedback device includes an input transmission gear and a double drive gear. The protrusions on the planetary carrier are all inserted into the corresponding second limiting holes on the second connecting side plate of the input transmission gear. After the teeth of the input transmission gear pass through the internal gear, they mesh with the large gear of the double drive gear mounted above it. The small gear of the double drive gear meshes with the swing arm teeth.

[0007] Preferably, the gear cover has a recessed groove inside for limiting the swing of the top and bottom points of the rocker arm teeth, and the two inner sidewalls of the limiting groove are adapted to the shape of the two sides of the lower swing end of the rocker arm teeth.

[0010] Preferably, the battery holder has a rotating shaft connecting seat at each of its two ends. The rotating shaft is fixedly installed on the rotating shaft connecting seat. The torsion spring is movably sleeved on the rotating shaft. The rotating end of the shoulder key is rotatably connected to the rotating shaft.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please refer to Figure 1 The present invention provides a shoulder button force feedback adjustment mechanism for a game controller, including shoulder buttons 1, battery bracket 3, circuit board 4 and force feedback adjustment mechanism 5, etc. The components of this embodiment will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 5 and Figure 6 As shown, the shoulder button 1 can be rotatably mounted at the end of the battery bracket 3 via the pivot 11 and the torsion spring 12. The battery bracket 3 and the force feedback adjustment mechanism 5 are respectively fixedly mounted on the circuit board 4. The bottom of the shoulder button 1 is fixedly connected to the push rod 2 and is positioned opposite to the input end of the force feedback adjustment mechanism 5.

[0027] Among them, the shoulder button 1 is the component directly operated by the user. The user triggers the subsequent mechanical structure movement by pressing the shoulder button 1. The push rod 2 receives the pressing action of the shoulder button and transmits the movement to the input end of the force feedback adjustment mechanism 5. Through cooperation with the rotating shaft 11 and the torsion spring 12, it provides basic rebound force and enhances the button feel. The force feedback adjustment mechanism 5 can accurately adjust the output power according to different game scenarios and user needs, thereby achieving different force feedback effects and improving the user's gaming experience.

[0028] To enhance the gaming experience and provide feedback at different intensity levels, the force feedback adjustment mechanism 5 can be configured as a two-stage gear feedback device or a three-stage gear feedback device.

[0029] Specifically, both the two-stage gear feedback device and the three-stage gear feedback device can include a motor 51, a sun gear 52, planet gears 53, a planet carrier 54, an internal gear 55, an output gear set, a rocker arm gear 56, a motor base 57, and a gear cover 58. The motor base 57 is fixedly mounted on the circuit board 4. The rocker arm gear 56 is oscillatingly mounted inside the gear cover 58 via a connecting shaft 561. The pressing part of the rocker arm gear 56 extends out of the gear cover 58 and is located directly below the push rod 2. The internal gear 55 is fixedly connected between the gear cover 58 and the motor base 57. The motor 51 is fixedly mounted on the outside of the motor base 57. Several planet gears 53 are provided and all mesh with the gear ring of the internal gear 55 through the planet carrier 54. The sun gear 52 is drivenly connected to the output shaft of the motor 51 and passes through the planet carrier 54 to mesh with each planet gear 53. Each planet gear 53 is drivenly connected to the output gear set through the planet carrier 54. The output gear set meshes with the rocker arm gear 56.

[0030] Preferably, in order to limit the swing range of the rocker arm tooth 56, the inside of the gear cover 58 may be recessed with a limiting groove 581 for limiting the swing of the top and bottom points of the rocker arm tooth 56, and the two inner sidewalls of the limiting groove 581 are adapted to the shape of the two sides of the lower swing end of the rocker arm tooth 56.

[0031] Furthermore, the planet carrier 54 may have a through hole 541 in the middle for the sun gear 52 to pass through, and the planet carrier 54 may have a number of planet gear shafts 542, with a number of planet gears 53 respectively fitted on their respective planet gear shafts 542.

[0032] In this embodiment, the circuit board is provided with two detection chips. The force feedback adjustment mechanism 5 may also include a magnet 59 for detecting the angular position of the swing arm tooth 56. The magnet 59 is fixedly connected to the side wall of the lower swing end of the swing arm tooth 56 near the gear cover 58. Each detection chip is respectively connected to the magnet 59 on the force feedback adjustment mechanism 5.

[0033] In practice, the motor 51 drives the sun gear 52 to rotate as a power source. The sun gear meshes with multiple planetary gears 53 and drives them to rotate on their own axis and revolve around the internal gear 55. The power is transmitted to the output gear set through the planet carrier 54. The output gear set drives the swing arm tooth 56 to swing. Different transmission ratios and force feedback effects are achieved according to different output gear set structures (two-stage gear feedback device and three-stage gear feedback device). The pressing part of the swing arm tooth 56 can apply a reaction force to the push rod 2 to meet the immersive needs of different game scenarios.

[0034] Preferably, the gear cover 58 can be fixedly mounted on the motor base 57 by bolts, the connecting shaft 561 is fixedly connected between the gear cover 58 and the head end of the motor base 57, the rotating end of the rocker arm gear 56 is rotatably connected to the connecting shaft 561, and the internal gear 55 is fixedly connected to the gear cover 58 by bolts.

[0035] The gear cover 58 and the internal gear 55 of the motor base 57 form a closed cavity, which can prevent dust and debris from entering the gear transmission system, reduce gear wear, ensure the stability of force feedback transmission, and extend service life.

[0036] Preferably, the battery holder 3 may be provided with a rotating shaft connecting seat 31 at both ends. The rotating shaft 11 is fixedly installed on the rotating shaft connecting seat 31. The torsion spring 12 is movably sleeved on the rotating shaft 11. The rotating end of the shoulder key 1 is rotatably connected to the rotating shaft 11. The two abutting ends of the torsion spring 12 abut against the bottom of the shoulder key 1 and the top of the rotating shaft connecting seat 31, respectively.

[0037] Example 1

[0038] like Figures 2 to 4 As shown, the output gear set of the two-stage gear feedback device may include an output drive gear 61. The protrusions on the planet carrier 54 are all inserted into the first limiting holes 610 corresponding to the first connecting side plate of the output drive gear 61. The teeth of the output drive gear 61 pass through the internal gear 55 and mesh with the rocker arm teeth 56.

[0039] The working principle of this first embodiment is as follows:

[0040] When the force feedback adjustment mechanism 5 is set as a two-stage gear feedback device, the output shaft of the motor 51 drives the sun gear 52 to rotate, causing each planet gear 53 to revolve around the internal gear 55. At the same time, the power is transmitted to the output drive gear 61 through the planet carrier 54. At this time, the planet gear 53 and the planet carrier 54 rotate on the internal gear 55 as the first-stage driven gears. The output drive gear 61 acts as the drive wheel of the second-stage transmission, directly driving the rocker arm gear 56 to rotate around the connecting shaft 561. The position of the magnet 59 of the rocker arm gear 56 is monitored in real time by two detection chips located on the circuit board 4. The motor 51 can output the corresponding speed according to the different positions of the magnet 59. The rocker arm gear 56 then receives different driving force reactions to the push rod 2, so that the shoulder key 1 can experience different resistance forces.

[0041] Example 2

[0042] like Figures 7 to 9 As shown, the output gear set of the three-stage gear feedback device may include an input transmission gear 71 and a double drive gear 72. The protrusions 543 on the planet carrier 54 are all inserted into the corresponding second limiting holes 710 opened on the second connecting side plate of the input transmission gear 71. After the teeth of the input transmission gear 71 pass through the internal gear 55, they mesh with the large gear 721 of the double drive gear 72 installed above it. The small gear 722 of the double drive gear 72 meshes with the rocker arm teeth 56.

[0043] The working principle of this second embodiment is as follows:

[0044] When the force feedback adjustment mechanism 5 is set as a three-stage gear feedback device, the output shaft of the motor 51 drives the sun gear 52 to rotate, causing each planet gear 53 to revolve around the internal gear 55. At the same time, the power is transmitted to the input transmission gear 71 through the planet carrier 54. The input transmission gear 71 synchronously drives the large gear 721 of the double drive gear 72, causing its small gear 722 to further drive the rocker arm gear 56. The planet gears 53 and the planet carrier 54 rotate on the internal gear 55 as the first-stage driven gears, synchronously making the input transmission gear the second-stage drive gear. At the same time, the double drive gear 72 acts as the third-stage drive gear, thereby causing the rocker arm gear 56 to rotate around the connecting shaft 561 as the center. The two detection chips on the circuit board 4 monitor the position of the magnet 59 on the rocker arm gear 56 in real time and dynamically adjust the speed of the motor 51. The torque is amplified through the three-stage feedback gear set, and the rocker arm gear 56 receives different driving force reactions, which are given to the push rod 2, so that the shoulder key 1 experiences different resistance forces.

[0045] In addition, when the gamer turns off the device's force feedback function, pressing down the shoulder button and the lever will push the force feedback component's swing arm tooth all the way down, resulting in no resistance experience.

[0046] In summary, the force feedback adjustment mechanism of this invention uses a motor to drive the sun gear, which in turn drives the planetary gears and planet carrier to rotate. This, in turn, drives the output gear set to swing the swing arm teeth, thereby applying a dynamically adjustable reaction force to the shoulder button. The two-stage gear feedback device enables rapid response and torque output, while the three-stage gear feedback device enables more complex transmission ratios and torque amplification, providing more precise force feedback gradations and strong reaction force to meet the needs of different game scenarios and significantly improve the interactive experience of the game controller.

[0047] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
