Abstract

The utility model relates to the technical field of simulated steering wheels, and discloses a simulated self-resetting steering wheel rotation device, including an assembly shell, a connecting seat, a steering shaft, a steering motor, a simulated steering wheel, a drive shaft end, a drive shaft end, a gear column, a base, a limit sleeve, a limit side groove, a limit slide, a support sleeve, an adjustable telescopic shaft, a clamp, and a support spring. In the utility model, the limit slide on the inner side of the limit sleeve is slidably clamped with the inside of the limit side groove, and the support spring inside the support sleeve always presses the limit slide upward through the support sleeve. When pressing, the limit sleeve always supports the limit teeth on the connecting plate and the gear column in a fitting manner. In this way, when the bottom side of the limit sleeve becomes thinner due to friction, the support spring can make the limit teeth on the surface of the connecting plate on the limit sleeve always mesh with the gear column, and no gap separation will occur, thereby ensuring that the gear column can be normally rotated and limited, thereby ensuring that the steering wheel can be normally returned to the center control.

Description

Technical Field

[0001] The utility model relates to the technical field of simulated steering wheels, in particular to a simulated self-resetting steering wheel rotation device. Background Art

[0002] In the prior art, vehicle driving simulators are typically used to simulate real vehicle driving. Users can use them to practice driving skills or play games. The steering wheel mechanism, a core component frequently used by users in vehicle driving simulators, must accurately replicate the operating effects of a real vehicle to enhance the realism of the simulator's operation.

[0003] The existing steering wheel can be rotated and reset through motor control, and the end of the steering shaft can be engaged and limited by the gear column and the limit rack to limit the number of steering wheel rotations and prevent excessive rotation. However, when the limit rack slides left and right for a long time and contacts and rubs against the limit seat, the bottom side of the limit rack is prone to wear and thinning, resulting in a gradual increase in the distance between the limit rack and the gear column. When the gear column is separated from the limit rack, the steering shaft is prone to idling. When the feedback device on the motor cannot detect the stall current of the gear on the motor, the motor cannot control the steering wheel to produce a rotation function, resulting in the steering wheel being unable to return to normal use, affecting the simulation experience. For this reason, we propose a simulated self-resetting steering wheel rotation device. Utility Model Content

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a simulation self-resetting steering wheel rotation device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a simulated self-resetting steering wheel rotation device, including an assembly shell, a connecting seat, a steering shaft, a steering motor, a simulated steering wheel, and a drive shaft end, the end of the drive shaft end is installed with a gear column, the top of the connecting seat is installed with a base, the external sliding sleeve of the base is provided with a limit sleeve, and the upper surface of the limit sleeve is provided with a limit tooth meshing with the gear column teeth through the surface of the connecting plate, and the front and rear sides of the base are provided with limit side grooves, and the inner side of the limit sleeve is installed with a limit slide penetrating the limit side groove, and the bottom of the limit slide is installed with a support sleeve, and the internal telescopic structure of the support sleeve is provided with an adjustable telescopic shaft, and the top of the adjustable telescopic shaft is installed with a clamping member that is engaged with the internal limit of the support sleeve, and the top of the clamping member is installed with a support spring connected to the top side support of the support sleeve.

[0006] Preferably, when the limiting sleeve presses the limiting slide according to the support spring inside the supporting sleeve, the limiting sleeve located outside the base can rebound accordingly so that the limiting teeth on the connecting plate and the gear column are in a fitting and engaging state.

[0007] Preferably, a spherical groove is provided at the end of the adjustable telescopic shaft, a movable clamping ball is movably engaged inside the spherical groove, and a docking groove is provided at the bottom side of the limiting side groove.

[0008] Preferably, the support sleeve is engaged in a limited sliding manner with the docking groove inside the limited side groove through a movable locking ball at the end of the adjustable telescopic shaft.

[0009] Preferably, a buffer tooth pad is provided on the outer wrapping sleeve of the gear column, and the buffer tooth pad has the same shape as the gear column's own tooth group and has deformation characteristics;

[0010] Preferably, when the gear column is engaged with the limiting teeth on the connecting plate, the buffer tooth pads on the periphery of the gear column and the multiple groups of limiting teeth are in a mutually engaged and extruded state.

[0011] Beneficial effects

[0012] The utility model provides a simulated self-resetting steering wheel rotation device. It has the following beneficial effects:

[0013] 1. A simulated self-resetting steering wheel rotation device. In this article, after the simulated steering wheel is installed with the end of the steering shaft, when the steering motor is operated to rotate, the driving shaft end of the steering shaft end can be driven by the gear column and the limit teeth on the connecting plate after being linked and controlled, so that the limit sleeve is located outside the base for left and right movement control, and the limit slide on the inside of the limit sleeve can produce left and right limit cooperation with the inside of the limit side groove. When the steering motor detects that the driving gear inside the assembly shell is blocked due to the limit of the limit sleeve, the feedback device on the steering motor can control the driving gear on the steering motor to rotate, and the driving gear then drives the steering shaft inside the assembly shell to rotate accordingly, and the simulated steering wheel can produce linked rotation and reset. If the bottom side of the limit sleeve is in contact with the outside of the base for a long time, When the sliding friction causes wear and thinning, the traditional limit sleeve will cause the limit teeth on the connecting plate to gradually disengage from the gear column, causing the gear column to rotate idly. The limit slide on the inside of the limit sleeve is slidably engaged with the inside of the limit side groove, and the support spring inside the support sleeve always presses the limit slide upward through the support sleeve. When pressing, the limit sleeve always fits and supports the limit teeth on the connecting plate and the gear column. In this way, when the friction on the bottom side of the limit sleeve becomes thinner, the support spring can always generate a rebound support force to press and support the limit slide. Similarly, the limit teeth on the surface of the connecting plate on the limit sleeve will always be in meshing state with the gear column, and no gap separation will occur, ensuring that the gear column can rotate and limit normally, thereby ensuring that the steering wheel can be normally returned to control, improving the user's simulation experience.

[0014] 2. A simulated self-resetting steering wheel rotation device, when the gear column is engaged and driven with the limit teeth on the connecting plate, the gear column can be limited by sliding left and right through the limit sleeve located outside the base, and the tooth surface of the gear column is covered with a layer of buffer tooth pad, which itself has deformation characteristics. When the gear column is engaged and rotated with the limit teeth on the connecting plate, the buffer tooth pad on the periphery of the gear column can first engage with multiple groups of limit teeth to prevent the gear column's own teeth from directly wearing and contacting with the limit teeth, and the wear between the gear column and the limit teeth can be reduced through the deformation elasticity of the buffer tooth pad itself, thereby reducing the wear between the gear column and the limit teeth and extending the service life of the gear column and the limit teeth.
