Technical Field

The invention belongs to the field of automobile parts, and particularly relates to an improved automobile pedal device.

Background

With the increase of the income of families, more and more automobiles enter common families and become tools for people to go out. In the existing family car, whether an automatic transmission car, a manual transmission car or an electric car or a hybrid car, an accelerator pedal and a brake pedal are arranged at the driving position, and the corresponding acceleration or braking function is realized when the car is stepped.

An accelerator pedal, also called an accelerator pedal, is a component for controlling the opening of an engine throttle valve so as to control the power output of the engine, and an electronic pedal is generally adopted on many automatic transmission automobiles at present, namely, the accelerator pedal is not mechanically connected with the throttle valve, but the opening of the throttle valve is controlled by a displacement sensor. The automatic transmission automobile is not in a clutch state, and the speed is increased quickly when an accelerator pedal is pressed down, so that some people can often press down the accelerator pedal as a brake pedal due to carelessness or emergencies in the use process of the automatic transmission automobile, and accidents are caused. Especially, the automobile is more and more popular now, and when meeting emergency, the mistake is more easily taken accelerator pedal as brake pedal with many novice drivers on the road, and the accelerator pedal is stepped on suddenly and leads to becoming serious traffic accident.

In the normal driving process, a driver can slowly step on the accelerator to gradually accelerate the vehicle, and cannot step on the accelerator pedal suddenly, so that the driver can judge that the accelerator pedal is stepped on mistakenly, and when the accelerator pedal is stepped on mistakenly, if the driver can timely stop stepping on the accelerator, accidents can be avoided or reduced to a certain extent. Therefore, the application provides further design and improvement on the existing automobile accelerator pedal aiming at the problem.

The traditional automobile accelerator pedal is not provided with a locking mechanism, and the accelerator pedal can be suddenly stepped to the bottom, so that great danger is brought to the action in an emergency situation. In this application, set up locking mechanism on automobile pedal, the emergence of avoiding suddenly stepping on the throttle condition that can be fine. Under the normal condition, when the accelerator pedal is stepped on by the foot, the second pawl plate is driven to synchronously rotate, the second pawl plate drives the second locking plate to rotate through a second ratchet and pawl structure on the second pawl plate, the sliding block is positioned at one end in the sliding groove, the first pawl on the sliding block at the position is not locked with the first locking plate, and therefore the first locking plate cannot be driven to rotate by the rotation of the second locking plate, and the accelerator pedal stepping operation is normal. Meanwhile, under the normal condition, when the brake pedal is stepped on by a foot, the first locking plate is driven to synchronously rotate, and at the moment, the first locking plate is not locked with the first pawl, so that the normal operation of stepping on the brake is realized.

Under the special condition, when stepping on the brake pedal suddenly, drive first locking plate synchronous rotation, first locking plate also does not lock with first pawl this moment, belongs to normal sudden braking operation.

Under the special circumstances, when stepping on accelerator pedal suddenly, drive the synchronous rotation of second pawl board, second pawl board drives through the second ratchet pawl structure on it the second lock plate rotates, this in-process, owing to step on the produced acceleration of accelerator pedal suddenly, the sliding block removes to the other end of spout under the inertial action, and on this position, first pawl and first lock plate locking, when stepping on accelerator pedal suddenly, drive first lock plate and rotate, first lock plate drives brake pedal and rotates, plays the effect of brake, and this unusual driver of reminding too has stepped on the mistake simultaneously.

In addition, in this application, the opening switch and the closing switch 42 of the electromagnet 411 may be further connected to the oil path control circuit: if the accelerator pedal is normally powered on, namely the accelerator pedal is stepped on, the throttle valve is opened, and the automobile is accelerated; after the opening switch on the electromagnet is triggered to be opened, the electronic component on the accelerator pedal is powered off, namely the accelerator pedal is stepped on, the throttle valve is not opened, and the throttle valve is opened only after the electromagnet is closed.

In the present application, the electromagnet 441, the on-switch, and the off-switch 42 are powered by a built-in battery, or are connected to a vehicle-mounted power supply through a circuit structure. In this application, assembly, linkage structure between brake pedal, accelerator pedal and the automobile body also are conventional technique.

In this application, set up locking mechanism on automobile pedal, the emergence of avoiding suddenly stepping on the throttle condition that can be fine. Under normal conditions, when the accelerator pedal 132 is stepped on by foot, the second pawl plate 6 is driven to synchronously rotate, the second pawl plate 6 drives the second locking plate 2 to rotate through the second ratchet and pawl structure on the second pawl plate, in the process, the sliding block 431 is located at one end of the sliding groove 44, the first pawl 43 on the sliding block 431 at the position is not locked with the first locking plate 5, and therefore, the rotation of the second locking plate 2 cannot drive the first locking plate 5 to rotate, and normal accelerator stepping operation is performed. Meanwhile, under normal conditions, when the brake pedal 112 is stepped on by a foot, the first locking plate 5 is driven to rotate synchronously, and at this time, the first locking plate 5 is not locked with the first pawl 43, which belongs to normal operation of stepping on the brake.

Under special circumstances, when the brake pedal 112 is suddenly stepped on, the first locking plate 5 is driven to synchronously rotate, and at this time, the first locking plate 5 is not locked with the first pawl 43, which belongs to normal sudden braking operation.

Under special circumstances, when the accelerator pedal 132 is suddenly stepped on, the second pawl plate 6 is driven to synchronously rotate, the second pawl plate 6 drives the second locking plate 2 to rotate through the second ratchet and pawl structure on the second pawl plate, in the process, due to the acceleration generated by the sudden stepping on of the accelerator pedal, the sliding block 431 moves to the other end of the sliding groove 44 under the action of inertia, in the position, the first pawl 43 is locked with the first locking plate 5, when the accelerator pedal 132 is suddenly stepped on, the first locking plate 5 is driven to rotate, the first locking plate 5 drives the brake pedal 112 to rotate, the effect of braking is achieved, and meanwhile, the abnormality also reminds a driver of stepping on the accelerator pedal in a wrong way.

In the above, this application provides an improved generation automotive pedal device, when the user steps on the gas as the brake because of the incident mistake, is connected accelerator pedal and brake pedal through safety mechanism, and only when the user realizes misoperation and steps on brake pedal, just enables accelerator pedal and brake pedal separation to prevent to turn into more serious accident.

The scope of the present invention includes, but is not limited to, the above embodiments, and the present invention is defined by the appended claims, and any alterations, modifications, and improvements that may occur to those skilled in the art are all within the scope of the present invention.
