Description

Fixed control automobile accelerator pedal device

The technical field is as follows:

the utility model relates to an automobile manufacturing and safe driving can reduce and avoid the traffic accident that often happens that the driver steps on by mistake the accelerator pedal as the brake pedal.

Background art:

it is known that in order to enable a vehicle to run at a proper speed during driving of the vehicle, a driver puts his right foot on an accelerator pedal for more than 80% of the time, and the driver may develop a habit of extending his foot to the right-side accelerator pedal unconsciously over time, and once the driver encounters sudden road conditions, the driver may not pull back his foot or may be accustomed to extending his foot to the accelerator pedal, and the consequences are very feared. Some existing technologies do not seem to solve this problem well.

The invention content is as follows:

the utility model discloses set out from improving accelerator pedal mechanism, install one-way bearing 3, major axis 4 and electromagnetic clutch 6 below the accelerator pedal 2 of car, the 3 outer lanes of one-way bearing here correspond the hole tight fit with accelerator pedal 2, and the inner circle cooperates with major axis 4, and electromagnetic clutch 6 outer lane is fixed can not be rotatory, and the D shape end fixed coordination that the D shape hole of inner circle and major axis 4 correspond. The improved pedal mechanism can ensure that a driver does not need to step on the accelerator all the time when driving, the pedal still keeps at the position just before when the right foot leaves the accelerator pedal during driving, the engine can still obtain power, at the moment, the foot can be drawn back to be placed in front of the brake pedal, the driver can pay attention to the road condition to prepare to step on the brake at any time, the difference between the whole operation and the existing mode is not large, and the driver can adapt quickly.

Description of the drawings:

figure 1 is a block diagram of an embodiment of the present invention.

Fig. 2 is a diagram of an electronic control system in accordance with aspects of the present invention.

In fig. 1, a base (symbolizing a bottom plate of an automobile), an accelerator pedal 2, a one-way bearing 3, a long shaft 4, a positioning sheet 5 and an electromagnetic clutch 6 are arranged. In addition, a return spring is not shown and is well known in the art.

In the structure of the scheme, two one-way bearings 3 are arranged at two sides below the accelerator pedal (as shown in figure 1), the outer ring of each one-way bearing is tightly matched with a corresponding hole of the accelerator pedal 2, and the inner ring of each one-way bearing is matched with the long shaft 4; the notch of the outer ring of the electromagnetic clutch 6 is matched with the positioning sheet 5 (as shown in the figure) and can not rotate, and the end of the inner ring hole is a D-shaped hole; the long shaft 4 is movably matched with a bracket hole on the base 1, can relatively freely rotate, is matched with an inner hole of the one-way bearing 3, and can only rotate in one direction, the right end of the shaft is processed into a D shape and is fixedly matched with a D-shaped hole of an inner ring of the electromagnetic clutch, and the rotation of the long shaft 4 and the synchronous rotation of the inner ring of the electromagnetic clutch are ensured; the base 1 symbolizes the bottom plate of the automobile, and the positioning sheet 5 is fixed with the base 1 into a whole.

The above elements are discussed only in relation to axial rotation about the long axis 4, and the axial fixed relation is not discussed in detail with reference to fig. 1. In fig. 2, a fuse 21, a master switch 22, a normally closed switch 23, and an electromagnetic clutch 6 are connected in series.

The specific implementation mode is as follows:

after the automobile is ignited and electrified, the main switch 22 is turned on, the invention works in the way that the electromagnetic clutch 6 is electrified, the inner ring and the outer ring are strongly attracted, and the outer ring is fixed and can not rotate, therefore, the inner ring is fixed and can not rotate, because the D-shaped end of the long shaft 4 is fixedly matched with the D-shaped hole of the inner ring of the electromagnetic clutch, therefore, the long shaft 4 can not rotate freely (the axial fixed relation is not discussed), when the accelerator pedal is treaded to any position (for refueling the automobile) by the foot clockwise rotation and then lifted, the lower return spring has the tendency of reversely rotating and returning the pedal 2, because the pedal 2 is connected with the long shaft 4 through the one-way bearing 3, the pedal can only rotate clockwise relative to the long shaft 4, however, the long shaft 4 is restrained from rotating freely, and the accelerator pedal is restrained at the previous position and cannot be reset. So far the vehicle maintains the same driving power as it just before.

The normally closed switch 23 is composed of 5 similar switches (23 in fig. 2), all of which are connected in series, and is respectively arranged below a clutch pedal and a brake pedal of the automobile, and is also arranged on a gear lever handle, a steering wheel and an automobile dashboard, and the main switch 22 can be arranged on the automobile dashboard. When a clutch pedal or a brake pedal is stepped down by foot, the normally closed switch 23 is triggered, or the normally closed switch 23 on one of a gear lever handle, a steering wheel or an instrument panel is manually triggered, a circuit is disconnected, the electromagnetic clutch is immediately powered off, the inner ring and the outer ring are not attracted any more, the inner ring is in a free state and can rotate relatively, the long shaft 4 is free from restraint and can rotate freely and is in a movable fit relation with the rack, the accelerator pedal 2, the one-way bearing 3 in close fit with the accelerator pedal 2 and the long shaft 4 rotate anticlockwise under the action of the return spring, the accelerator pedal 2 is reset to an initial position, and the automobile engine enters an idling state.

When the foot leaves the clutch pedal and the brake pedal, the normally closed switch 23 is not triggered any more, and the normally closed switch 23 on the shift lever handle, the steering wheel or the instrument panel is not manually triggered, the switch 23 is closed, the system circuit is restored to be conducted, the electromagnetic clutch is electrified immediately, the long shaft 4 is locked again, and the operation is repeated in such a circulating way. If the fixed control driving system is not needed, only the main switch 22 arranged on the instrument panel is turned off, the system circuit is not electrified, the electromagnetic clutch is not electrified and does not work, the long shaft 4 can freely rotate, the pedal 2 and the long shaft 4 connected through the one-way bearing 3 can also freely rotate, and the driving control is the same as that in the past. The system has simple structure and little difference with the prior structure, thus not changing the prior driving habit of old drivers; the circuit is also simple to start frequently and can therefore be activated under various road conditions and speeds.

The normally closed switch 23 in fig. 2 may be a conventional electromechanical switch or a travel switch, and the working principle thereof is well known to those skilled in the art, and the details of the specific installation position are not important in the present invention and thus will not be described in detail herein.

As the above-mentioned operation mechanisms, i.e., the positions of the clutch pedal, the brake pedal, the shift lever, the steering wheel and the dashboard of the automobile, are well known, the specific method for installing the normally closed switch 23 is not technically difficult depending on the vehicle type, and thus is not shown or described in detail.
