[0025] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 6As shown, the function mode switching driving structure of the computer input device of the present invention includes a base 1, a power device, a transmission device, an execution device and a control device; wherein the base is a supporting component, which is fixed to the computer input device; the transmission device is respectively connected to the power device and the execution device, the execution device matches the function knob of the computer input device itself, and the execution device corresponds to multiple working positions; the control device controls the operation of the power device, and drives the execution device to move and switch between different working positions through the transmission device.

[0027] The power device is an electric motor 2, more specifically, the electric motor is a stepping motor, so that the control device can accurately control the operating angle of the electric motor according to different programs to make the work more accurate. The control device is connected to the electric motor through a data line 13; the transmission device includes a driving gear 3 and a driven gear 4 that are meshed with each other, the driving gear is connected to the output shaft 6 of the electric motor, the driven gear is movably connected to the base, and an eccentric output structure is arranged on the driven gear; the execution device includes a swing rod, the middle part of the swing rod is movably connected to the base, and the tail end of the swing rod is movably connected to the eccentric output device. When the driven gear rotates, the tail end of the swing rod is driven by the eccentric output device, thereby driving the head end of the swing rod to swing to different working positions under the drive of the driven gear.

[0028] A motor mounting plate 7 is vertically arranged on the base 1, the motor is fixed to the motor mounting plate, and the motor output shaft 6 is parallel to the base; the driving gear 3 is a spur gear, and the driving gear is coaxially connected to the motor output shaft, the driven gear 4 is a crown gear with a tooth surface facing the base, the gear shaft movably connects the driven gear to the base, and the gear shaft is perpendicular to the base, an eccentric truncated cone 5 as an eccentric output device is arranged on the upper spoke surface of the driven gear away from the base, the eccentric truncated cone is not coaxial with the driven gear, and the driven gear and the eccentric truncated cone are an integrated structure; the swing rod shaft 17 movably fixes the swing rod 18 to the base, and the swing rod shaft is perpendicular to the base, the tail end of the swing rod is provided with a connection hole 19 matched with the above eccentric truncated cone, and the head end of the swing rod swings in a plane parallel to the base. The eccentric output device can also be a cam structure arranged on the spoke surface of the driven gear. The eccentric output device can also adopt a cam structure coaxial with the driven gear, an elliptical wheel structure, or a cam structure not coaxial with the driven gear.

[0029] A raised gear mounting column 10 is arranged on the base, the gear shaft 9 passes through the driven gear and is fixed to the gear mounting column, an elastic support component is arranged around the gear mounting column, the upper and lower ends of the elastic support component respectively press against the base and the lower spoke surface of the driven gear, a gasket 12 is arranged between the upper end of the elastic support component and the lower spoke surface of the driven gear; the elastic support component is a compression spring 11a or an elastic support block 11b.

[0030] Figure 2 , Figure 3An elastic support block 11b is arranged around the gear mounting column. The upper and lower ends of the elastic support block respectively press against the base and the lower spoke surface of the driven gear. The elastic support block is made of elastic material and has wear-resistant characteristics. Figure 3 and Figure 4 A compression spring 11 is arranged around the gear mounting column, and the two ends of the compression spring press against the base and the driven gear respectively. The setting of the elastic support component ensures that the driven gear can rotate smoothly at a fixed position, thereby ensuring that the eccentric cone drives the swing rod to move more smoothly, avoiding misalignment and jitter in transmission, and a gasket 12 is arranged between the upper end of the elastic support component and the lower spoke surface of the driven gear, thereby further reducing the occurrence of vibration.

[0031] Fixed parts 14 are extended outward on both sides of the motor, and motor shock-absorbing gaskets 15 are arranged at fixed positions between the fixed parts and the motor mounting plate. The motor and the motor mounting plate are fixed by screws, and screw shock-absorbing gaskets 16 are arranged between the screws and the fixed parts on both sides of the motor, thereby reducing the vibration generated during the operation of the motor, improving the accuracy of the matching between the driving gear and the driven gear, and reducing noise.

[0032] The connecting hole set at the tail end of the swing rod is a waist-shaped hole, and the inner wall of the waist-shaped hole matches the outer wall of the eccentric cone, thereby ensuring that the eccentric cone slides in the waist-shaped hole, improving the stability of the swing rod in motion and its accuracy when it moves to the working position.

[0033] A raised pendulum rod fixing column is arranged on the base, the pendulum rod shaft passes through the pendulum rod and is fixed to the pendulum rod fixing column, a torsion spring 20 is arranged around the pendulum rod fixing column, and the two ends of the torsion spring are arranged on both sides of the pendulum rod head end respectively, and the two ends of the torsion spring are driven to rotate when the pendulum rod head swings.

When the driven gear rotates through a certain angle, the eccentric cone makes the swing rod reach the first working position, and the swing rod drives the roller at one end of the torsion spring to twist in the direction away from the smooth wheel, and drives the lever at the other end of the torsion spring to twist in the direction close to the ratchet gear, until the lever contacts and fits, and the lever is stuck in the tooth groove of the ratchet gear. When the user rotates the function knob, the ratchet gear rotates with the function knob, and the lever jumps in the tooth groove adjacent to the ratchet gear under the elastic force of the torsion spring. The lever plays a staged blocking role with force feedback. At this time, the function knob feeds back to the user with mechanical detent The function knob has a damped rotational touch feeling that is frustrating; when the driven gear rotates to another angle, the eccentric cone makes the swing arm reach the second working position, and the swing arm drives the lever at one end of the torsion spring to twist in the direction away from the ratchet gear, and at the same time drives the roller at the other end of the torsion spring to twist in the direction of the smooth wheel. At this time, the roller contacts and cooperates with the smooth wheel. When the user rotates the function knob, the function knob gives the user a smooth low-damping rotational touch feeling, so that the function knob can give the user a different use experience of the function knob when used in different programs or when different programs respond to the user's input. The above structure of the function knob, the structure of the two ends of the torsion spring, and the matching structure of the function knob and the torsion spring are the extension-related parts of an embodiment of the present invention to explain the driving effect played by the present invention in use. The function knob itself is a prior art and is not within the scope of protection of the present invention, and will not be repeated here. The specific working conditions and working methods corresponding to the swing arm or the actuator at different working positions can also be adjusted according to the specific structure of the function knob, and are not subject to the constraints of the above embodiments.
