A clamping ring 37 is arranged at the opening of the guide cavity, and the plug is limited in the guide cavity by the clamping ring 37 so as to enable the plug and the guide cavity to move relatively in a specific axial range. The sealing plug 3 is provided with a sealing plug medium channel 32, a sealing chamber A is used for feeding and discharging media through the sealing plug medium channel 32 on the sealing plug, the plug 4 is provided with a plug 41 which is used for plugging the sealing plug medium channel 32 when the sealing plug medium channel and the sealing plug are close to each other and opening the sealing plug medium channel 32 after the sealing plug medium channel and the sealing plug are separated, a pressure spring 6 which pushes the sealing plug 3 and the plug 4 to be separated is arranged between the sealing plug 3 and the plug 4, and the maximum elastic force of the pressure spring 6 is larger than the. In addition, the plug 4 is in sliding sealing fit with the inner wall of the clamping groove, an isolation cavity B is formed between the plug 4 and the sealing plug 3, a plug medium channel 42 used for guiding out a medium in the isolation cavity B is arranged on the plug 4, and the drift diameter of the plug medium channel 42 is larger than that of the sealing plug medium channel 32. The plug 4 is provided with a pressure spring clamping groove 43 for mounting a pressure spring.

In the practical use process of the device for preventing the accelerator from being stepped on by the mistake in the embodiment, when a driver steps on the accelerator pedal, the normal condition is generally that the accelerator pedal is gradually accelerated and is slowly pressed down, so that the push-pull rod 2 positioned below the accelerator pedal is stressed to move downwards, the return spring 5 is compressed, the medium in the sealing cavity A flows into the isolation cavity B through the sealing plug medium channel 32 and flows into the upper cavity of the cylinder body 1 through the plugging medium channel 42, as shown in figure 5, under the condition, the push-pull rod 2 is stressed to drive the sealing assembly to integrally move downwards, and the relative motion does not occur between the sealing plug 3 and the plugging plug 4.
When a driver lifts or gradually lifts the accelerator pedal, the push-pull rod 2 is reset upwards under the action of the reset spring 5, a medium enters the isolation cavity B through the plugging medium channel 42 under the action of pressure difference and gravity, and then flows back to the sealing cavity A through the sealing plug medium channel 32 and the one-way valve, and in the process, the one-way valve increases the back flow speed of the medium, so that the push-pull rod 2 can be reset quickly.
When an emergency occurs and a driver steps on an accelerator suddenly (please refer to fig. 3), the one-way valve is not closed, the sealing plug medium channel 32 cannot meet the medium discharge speed, so that the pressure of the sealing chamber a rapidly exceeds the pressure of the isolation cavity B, the pressure difference overcomes the elastic force of the pressure spring 6 and the gravity of the sealing plug 3, the sealing plug 3 rapidly moves upwards, and the sealing plug medium channel 32 is rapidly sealed by the plug 41 on the plug 4, so that the medium of the sealing chamber a cannot flow out; the faster the stepping speed, the higher the pressure rise in the sealing chamber a, which eventually results in the sealing plug 3 making a small stroke and then stopping against the plug 4. Since the stroke of the sealing plug 3 relative to the plug 4 is small, the downward movement of the push-pull rod 2 caused by the compression of the medium is also very small, so that the push-pull rod 2 can only generate a small pressing amount in the state.
When the accelerator pedal is in an initial position, the accelerator pedal can normally keep a normal idling speed, and when the accelerator pedal normally descends, the accelerator pedal firstly passes through an idling range and then is in an acceleration stage. Through the arrangement, when a driver steps on the accelerator suddenly, the push-pull rod can only move for a small distance, and the distance is within the idle speed range, so that the accelerator cannot generate a quick oiling action, the automobile cannot move quickly, traffic safety accidents are avoided, and the safety of personnel in the automobile is protected.
