DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3The utility model provides a technical solution: a progressive force feedback control button device, comprising a button housing 1, a button shell 201 is slidably connected to the inner side of the button housing 1, a circuit board 205 is fixedly installed on the top of the button shell 201, a progressive feedback component 300 is installed on the inner side of the button housing 1, and an elastic support component 400 is installed on the inner side of the button housing 1; through the coordinated use of the progressive feedback component 300 and the elastic support component 400 on the inner side of the button housing 1, the user can obtain a more realistic operating experience through progressive force feedback, and after the switch signal is triggered, the current real-time pressure can be used for adaptive changes. As the downward pressure continues to increase, the feedback force received is also continuously improved, achieving the effect of progressive feedback, so that the force feedback can become more realistic, which is conducive to improving the user's actual experience, thereby effectively improving the practicality of the control button device.

[0024] In this embodiment, the progressive feedback component 300 is a structure for providing certain feedback on the pressing force.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the progressive feedback component 300 includes a pressure sensor 301 integratedly installed on the outside of the circuit board 205, two fixed rods 302 fixed to the inner top wall of the button shell 201, a movable frame 303 fixed between the ends of the two fixed rods 302, two outer cylinders 304 fixed to the inner bottom wall of the button compartment body 1, two inner cylinders 305 fixed to the bottom of the movable frame 303, a main electromagnet 306 fixedly installed on the inner side of the outer cylinder 304, an auxiliary electromagnet 307 fixedly installed on the inner side of the inner cylinder 305, two positioning rods 308 fixed to the inner bottom wall of the button compartment body 1, a limit plate 309 fixed to the top of the positioning rod 308, and a microcontroller 310 detachably installed on the outside of the button compartment body 1.

[0026] It should be noted that a rubber sheet 202 is bonded to the top of the button shell 201, an elastic ring 203 is bonded between the inner top wall of the rubber sheet 202 and the top of the button shell 201, a trigger sheet 204 is bonded to the inner top wall of the rubber sheet 202, and a metal contact sheet 206 is integrated and installed on the outer side of the circuit board 205. The rubber sheet 202 is arc-shaped, and a cavity for installing the circuit board 205 is formed between the rubber sheet 202 and the opposite side of the button shell 201. The elastic ring 203 is located on the outer side of the circuit board 205, and the positions of the trigger sheet 204 and the metal contact sheet 206 correspond, so that the rubber sheet 202 can be pressed by the user, thereby compressing the elastic ring 203 and enabling the trigger sheet 204 to contact the metal contact sheet 206 to complete the transmission of the trigger signal. The principles of the generation and transmission of the trigger signal of the button are all existing public technologies, so they will not be elaborated in detail.

[0027] At the same time, the pressure sensor 301 is located below the trigger sheet 204, so that after the trigger sheet 204 contacts the metal contact sheet 206, pressure can be applied to the pressure sensor 301 through the metal contact sheet 206, wherein the portion where the metal contact sheet 206 contacts the pressure sensor 301 is fixed with a plastic shell, so that pressure can be applied to the pressure sensor 301 through the plastic shell, which is convenient for long-term use.

[0028] In addition, the inner cylinder 305 is slidably connected to the inner side of the corresponding outer cylinder 304, and the bottom of the inner cylinder 305 and the top of the outer cylinder 304 are both opened, so that the inner cylinder 305 can move normally on the inner side of the corresponding outer cylinder 304, and the positions of the main electromagnet 306 and the corresponding auxiliary electromagnet 307 correspond to each other, and the main electromagnet 306 and the corresponding auxiliary electromagnet 307 repel each other on opposite sides, so that the main electromagnet 306 can exert a repulsive force on the corresponding auxiliary electromagnet 307 after being energized, thereby achieving a force feedback effect.

[0029] In addition, the end of the positioning rod 308 passes through the bottom of the movable frame 303, so that the movable frame 303 can slide stably under the cooperation between the two positioning rods 308, and under the action of the limiting plate 309, it can also limit the movable distance of the movable frame 303 to prevent the movable frame 303 from detaching from the outside of the positioning rod 308.

[0030] In this embodiment, the elastic support assembly 400 is a structure for elastically supporting the button housing 201 .

[0031] like Figure 1 As shown, the elastic support assembly 400 includes a mounting tube 401 fixed to the inner bottom wall of the button housing 1 and having openings at the top and bottom, and an elastic member 402 fixed to the inner top wall of the button shell 201 .

[0032] It should be noted that the other end of the elastic member 402 is fixedly connected to the inner bottom wall of the button housing 1, and the elastic member 402 is located on the inner side of the mounting tube 401. The elastic member 402 may be a spring, so that the elastic member 402 can elastically support the button shell 201, and the movable frame 303 is located on the outer side of the mounting tube 401, so that the movable frame 303 can move normally.

[0033] The working principle of the above embodiment is:

[0034] When using this button for control, the rubber sheet 202 is pressed to deform the elastic ring 203, and the trigger sheet 204 is brought into contact with the metal contact sheet 206, thereby sending a corresponding electrical signal to the circuit board 205 to complete the control of the button, and continue to apply pressure to increase the pressure acting on the pressure sensor 301, and convert the pressure signal into an electrical signal through the pressure sensor 301, and transmit it to the microcontroller 310. Through the preset program of the microcontroller 310, different currents of different pressures are input to the main electromagnet 306, so that the repulsive force between the corresponding main electromagnet 306 and the auxiliary electromagnet 307 can be controlled. Different repulsive forces can be applied to the button shell 201 through the movable frame 303 and the fixed rod 302, and the reaction forces of different sizes can be increased as the pressure increases, thereby achieving the effect of progressive force feedback, making the user experience more realistic.

[0035] Compared with the prior art, the progressive force feedback control button device, through the coordinated use of the progressive feedback component 300 on the inner side of the button compartment body 1 and the elastic support component 400, can enable the user to obtain a more realistic operating experience through progressive force feedback. After triggering the switch signal, it can make adaptive changes according to the current real-time pressure. As the downward pressure continues to increase, the feedback force also continues to increase, achieving the effect of progressive feedback, so that the force feedback can become more realistic, which is beneficial to improving the user's actual experience, thereby effectively improving the practicality of the control button device and solving the problem that the existing button feedback force adjustment mechanism is inconvenient to adjust the feedback force according to the actual pressure size during actual use.

[0036] The electrical components appearing in the article are all electrically connected to the main controller and the external power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device that controls the main control computer, etc. It can be implemented through simple programming by technicians in the field, and they are all existing public power connection technologies and will not be described in detail in the article.
