[0031] Example

[0032] like Figure 1-5 As shown, the utility model provides an electronic deceleration pedal, including a pedal arm 1, a housing 2 is arranged on the top of the pedal arm 1, a rear cover 3 is arranged on the side of the housing 2 away from the pedal arm 1, a simulation block assembly 4 is arranged inside the housing 2, a top cover 5 is arranged on the top of the housing 2, a limit frame 6 is arranged at the bottom of the housing 2, the limit frame 6 is sleeved on the outside of the pedal arm 1, a damper assembly 7 is arranged on the side of the limit frame 6 away from the pedal arm 1, and a force sensor 8 and an angle sensor 9 are arranged on the outer surface of the housing 2. A rotating shaft is arranged on the pedal arm 1, and the angle sensor 9 is connected to the pedal arm 1 through the rotating shaft. When the pedal arm 1 is pressed down, it rotates along the rotating shaft, and then the angle of rotation is measured by the angle sensor 9.

[0033] The simulation block assembly 4 includes a simulation block 1 41, a simulation block 2 42, a simulation block 3 43 and a simulation block 4 44. The simulation block 1 41 is arranged below the top cover 5, the simulation block 2 42 is sleeved below the inside of the simulation block 1 41, the simulation block 3 43 is sleeved below the inside of the simulation block 2 42, and the simulation block 4 44 is sleeved below the inside of the simulation block 3 43. A spring 1 45 is arranged between the simulation block 1 41 and the simulation block 2 42, a spring 2 46 is arranged between the simulation block 2 42 and the simulation block 3 43, and a spring 3 47 is arranged between the simulation block 3 43 and the simulation block 4 44. A fixed rod is arranged on the top of the simulation block 1 42, and the force sensor 8 is arranged above the fixed rod. While the simulation block assembly 4 performs a pivoting movement around the force sensor 8, it can perform a relative horizontal movement with the pedal arm 1.

[0034] The connection between the pedal arm 1 and the simulation block assembly 4 is provided with a mounting groove 11. The number of mounting grooves 11 is 5 and they are evenly arranged above the pedal arm 1. A transmission assembly 12 is arranged in the mounting groove 11. The transmission assembly 12 includes a fixed block 121, a small ball 122 and a large ball 123. The fixed block 121 is arranged in the mounting groove 11. A spherical groove is arranged above the fixed block 121. Several small balls 122 are evenly arranged on the spherical groove to form a spherical concave surface. The large ball 123 is arranged above the spherical concave surface formed by the small balls 122. The top of the large ball 123 abuts against the simulation block 44. When the pedal arm 1 rotates, the fixed block 121 is driven to move. Since the top of the large ball 123 abuts against the simulation block 44, the large ball 123 rotates under the action of the small ball 122, thereby applying a horizontal force to the simulation block 44, that is, the pedal arm 1 transmits the force to the simulation block assembly 4 through the transmission assembly 12.

[0035] When the pedal arm 1 is stepped on, the pedal arm 1 rotates along the rotating shaft, and the left side of the pedal arm 1 moves upward, and the pressure is transmitted to the simulation block component 4 through the transmission component 12. Specifically, the pedal arm 1 drives the transmission component 12 to move, and the transmission component 12 transmits the pressure to the simulation block four 44. Through the setting of other simulation blocks and springs, the simulation block one 41 is driven to press upward, and then the fixed rod is driven to transmit the pressure to the force sensor 8. The force sensor 8 can detect the pressure, thereby obtaining the pressure when the pedal arm 1 is pressed downward.

[0036] The damper assembly 7 includes a damping base 71, a damping piston 72 and a damping push rod 73. The damping base 71 is arranged on the side of the limit frame 6 away from the pedal arm 1. The damping piston 72 is arranged inside the damping base 71. The damping push rod 73 is arranged on the pedal arm 1, and the other end of the damping push rod 73 abuts against the damping piston 72. A leather cup 74 is arranged between the damping base 71 and the damping piston 72. Frictional force is generated between the leather cup 74 and the damping piston 72, thereby providing feedback to provide pedal force. A shift fork 10 is arranged on the pedal arm 1, and the damping push rod 73 is connected to the pedal arm 1 through the shift fork 10.

[0037] It also includes a controller, which is electrically connected to the force sensor 8 and the angle sensor 9. The force sensor 8 and the angle sensor 9 send measured data to the controller. The controller obtains the specific position of the pedal after analysis, and then controls the downward position of the pedal.

[0038] The specific connection methods of each part all adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0039] Working principle: When the brake pedal is depressed, the pedal arm 1 pivots around the angle sensor 9 and provides a brake angle electrical signal. The simulation block pivots around the force sensor 8 and outputs a brake pedal force signal. The springs between the simulation blocks are compressed, move relative positions, and feedback the pedal force. During the compression process, the simulation block assembly undergoes horizontal relative displacement with the pedal arm 1. When the brake pedal is released, during the pedal resetting process, the spring in the simulation block assembly 4 overcomes the drag force generated by the vacuum of the damper assembly 7, thereby realizing the pedal rebound hysteresis force.

[0040] Therefore, the utility model adopts an electronic deceleration pedal of the above structure to control the vehicle's braking system through electronic signals, making braking smoother and more precise, thereby improving the driving experience; compared with traditional mechanical braking systems, electronic braking systems usually have more self-diagnosis functions and can provide easier fault diagnosis and maintenance.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
