Device for preventing stepping on accelerator by mistake and vehicle

Abstract

The invention relates to a device for preventing stepping on an accelerator by mistake and a vehicle. The device comprises a cylinder body and a push-pull rod installed in the cylinder body in a guiding mode. The cylinder body is connected with an accelerator pedal in a transmission mode, and the push-pull rod is connected with a vehicle body. The push-pull rod is slidably in seal fit with the cylinder body through a sealing assembly installed on the end portion of the push-pull rod, and the sealing assembly comprises a plug connected with the push-pull rod and a sealing plug slidably in sealfit with the inner wall surface of the cylinder body. A sealing cavity is formed between the sealing plug and the cylinder body, and the plug and the sealing plug are capable of relatively moving within a specific axial range through limitation of a limiting structure. A compression spring is arranged between the sealing plug and the plug, and a sealing plug medium passage is formed in the sealingplug. A plug head is arranged on the plug, and when the relative movement speed of the cylinder body and the push-pull rod is higher, and pressure in the sealing cavity is suddenly increased to causethe sealing plug to move close to the plug, the plug blocks the sealing plug medium passage to prevent the cylinder body and the push-pull rod from continuing the relative movement.

Description

technical field [0001] The invention relates to an anti-acceleration device and a vehicle. Background technique [0002] At present, when the vehicle is designed, the accelerator pedal and the brake pedal are generally arranged on the lower right front of the driver, and the two positions are very close, so that the driver can operate it. However, the functions of the gas pedal and the brake pedal are different. Stepping on the gas pedal is to make the car start or accelerate, and stepping on the brake pedal is to slow down or stop the car. It is completely two opposite operations. Under normal circumstances, the driver will not mistake the accelerator pedal for the brake pedal, but in reality, for example, when a novice driver is not proficient in driving, or the driver encounters an unexpected situation, such as in order to avoid sudden pedestrians, In the case of vehicles, it is especially easy to step on the accelerator pedal as a brake pedal by mistake, and step on it ...

Problems solved by technology

Under normal circumstances, the driver will not mistake the accelerator pedal for the brake pedal, but in reality, for example, when a novice driver is not proficient in driving, or the driver encounters an unexpected situation, such as in order to avoid sudden pedestrians, In the case of vehicles, it is especially easy to step on the accelerator pedal as a brake pedal by mistake, and step on it very hard. If you step on the bottom quickly, the car will gain the maximum speed in an instant, resulting in a car accident and causing the parties to pay a heavy price.
