ACCELERATOR DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18608020 titled 'ACCELERATOR DEVICE
Simplified Explanation:
The power transmission mechanism of an accelerator device applies a reaction force to a pedal lever using a driving force from a drive source. It involves a first power transmission member, a second power transmission member, a coupling elastic member, and an actuator lever.
- The mechanism includes a first power transmission member with a first stopper that receives the driving force from the drive source.
- A second power transmission member has a second stopper that contacts the first stopper.
- The first and second stoppers are separated in an initial state but come into contact when the first power transmission member is driven against the elastic force of the coupling elastic member by energizing the drive source.
Key Features and Innovation:
- Utilizes a coupling elastic member to transmit driving force efficiently.
- Incorporates stoppers on power transmission members for controlled contact.
- Enables precise application of reaction force to the pedal lever.
Potential Applications:
- Automotive industry for accelerator pedal mechanisms.
- Industrial machinery for controlled power transmission.
- Robotics for precise actuation systems.
Problems Solved:
- Ensures accurate and controlled transmission of power.
- Provides a reliable mechanism for applying reaction force.
- Enhances overall performance and efficiency of accelerator devices.
Benefits:
- Improved precision in power transmission.
- Enhanced safety and control in accelerator mechanisms.
- Increased reliability and durability of the system.
Commercial Applications:
The technology can be applied in automotive manufacturing for accelerator pedal systems, industrial machinery for controlled power transmission, and robotics for precise actuation mechanisms.
Questions about the Technology: 1. How does the coupling elastic member enhance the efficiency of power transmission in this mechanism? 2. What are the specific safety benefits of the controlled contact between the stoppers on the power transmission members?
Original Abstract Submitted
A power transmission mechanism of an accelerator device includes a first power transmission member, a second power transmission member, a coupling elastic member, and an actuator lever, and applies a reaction force to a pedal lever via the first power transmission member, the second power transmission member, and the actuator lever using a driving force of a drive source. The first power transmission member has a first stopper, and the driving force is transmitted to the first power transmission member. The second power transmission member has a second stopper that comes into contact with the first stopper. The first stopper and the second stopper are separated from each other in an initial state, and when the drive source is energized, and come into contact with each other when the first power transmission member is driven against an elastic force of the coupling elastic member by energizing the drive source.
