Description
Technical field
The present invention relates to brake pedal technical field, especially relate to a kind of brake pedal unit.
Background technology
The advantages such as electric automobile is quiet with it, low-carbon environment-friendly are flourish under national policy strength promotes, but battery
Energy storage technology remains electronic bottleneck at present, limits electric automobile course continuation mileage and improves.In not making a breakthrough property of battery technology
Before, save energy expenditure during electric automobile during traveling, with good conditionsi in the case of reclaim electric automobile energy and become and currently may be used
The selection scheme performed.
Brake energy recovery is the principal mode reclaiming braking energy in electric automobile during traveling, and when it is by slowing down, motor turns
Rotor speed is transformed into power generation mode higher than stator rotary rpm by motor and charges battery energy storage device, passes through cutting magnetic line
Rotor is formed retroaction resistance torque and makes electric automobile slow down.
Working under braking mode, electric vehicle brake power is mechanical braking force and the summation of regeneration mode brake force；
If mechanical braking force is detected, can preferably regulate the size of regenerative braking force, make regenerating braking energy make full use of and turn
Change in battery energy storage unit.But existing brake pedal unit can not detect the situation of pedal in real time.
Summary of the invention
Not enough for prior art, the technical problem to be solved is to provide a kind of brake pedal unit, and it can
Continuous detecting goes out position and the speed of brake pedal.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is:
This brake pedal unit, including brake pedal installing rack and brake pedal arm, also includes for detecting brake pedal
The arm anglec of rotation and the photoelectric encoder of speed, described photoelectric encoder is located on brake pedal installing rack, brake pedal arm with
It is connected by rocker arm body between photoelectric encoder.
Further, described rocker arm body includes that rocking arm, described brake pedal arm are provided with chute, and one end activity sets
In chute, the rocking arm other end is connected with the power shaft of photoelectric encoder.
Described rocker arm body is positioned in the middle of brake pedal arm and photoelectric encoder.
Described one end is provided with roller, and roller is positioned in chute.
The side of described brake pedal arm is provided with projection, and described chute is located on projection.
The described rocking arm other end is connected by the power shaft of flat key with photoelectric encoder.
Described one end is provided with the cylindrical bar being positioned in chute.
Described cylindrical bar is provided with nylon jacket.
The present invention compared with prior art, has the advantage that
This brake pedal unit in the case of not changing current brake pedal overall structure, by brake pedal total in
Photoelectric encoder continuous detecting can go out position and the speed of brake pedal, and then identifies Current mechanical brake force size and driving
The emergency degree of member's braking, can accurately regulate the moment size of motor regenerative braking by these data, is ensureing braking ability
In the case of use motor regenerative braking to greatest extent, so that braking energy is recycled to greatest extent.
Accompanying drawing explanation
Content expressed by width accompanying drawing each to this specification and the labelling in figure are briefly described below:
Fig. 1 is brake pedal unit structural representation of the present invention.
Fig. 2 is brake pedal unit partial sectional view of the present invention.
Fig. 3 is brake pedal unit partial schematic diagram of the present invention.
In figure: 1. brake pedal installing rack, 2. brake pedal arm, 3. rocking arm, 4. photoelectric encoder, 5. nylon jacket, the most flat
Key, 7. chute.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further details of
Explanation.
As shown in Figure 1 to Figure 3, this brake pedal unit, including brake pedal installing rack 1 and brake pedal arm 2 and use
In the detection brake pedal arm anglec of rotation and the photoelectric encoder 4 of speed, wherein, brake pedal arm 2 is located at braking by rotating shaft
Pedal installing rack 1, brake pedal arm 2 can rotate around the shaft, and photoelectric encoder 4 is fixed on brake pedal installing rack 1, system
Move and be connected by rocker arm body between pedal arm with photoelectric encoder.
Rocker arm body is positioned in the middle of brake pedal arm and photoelectric encoder, compact conformation, it is simple to arrange.Rocker arm body includes
Rocking arm 3, brake pedal arm 2 is provided with chute 7, and one end is actively installed in chute, the rocking arm other end and photoelectric encoder
Power shaft is connected.
Preferably, rocking arm 3 one end is provided with roller, and roller is positioned in chute；Or one end is provided with and is positioned in chute
Cylindrical bar, and on cylindrical bar, it is provided with nylon jacket 5, it is to avoid braking abnormal sound.The rocking arm other end is by flat key 6 and photoelectric encoder
Power shaft is connected, and attachment structure is simple.
The side of brake pedal arm 2 is provided with projection, and chute is located on projection, and projection is bolted on brake pedal arm
On, do not interfere with the structural strength of brake pedal arm.
When driver step on brake pedal be braked time, brake pedal arm rotates around the shaft, and then drives solid with it
Chute even rotates, and during runner movement, nylon jacket is moved in its groove, and band motion rocker arm rotates, due to rocking arm and photoelectric coding
Device power shaft is connected, and photoelectric encoder power shaft can be sent to upper ECU, host computer ECU pair by encoder by impulse form
Umber of pulse counts, and then detects the brake pedal anglec of rotation and speed, and calls corresponding automatically controlled program to motor braking energy
Amount recovery is optimized regulation.
In the case of not changing brake pedal overall structure, by photoelectric encoder to brake pedal corner and driver
Braking emergency degree detects, thus regulates the moment size of motor regenerative braking, so that regenerating braking energy is the most sharp
With and be transformed in battery energy storage unit.
Testing result can be used for regulating the energy of motor regenerative braking, recovery maximum in the case of ensureing braking effect
The energy of motor braking.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way
Restriction, as long as have employed the design of the present invention and the improvement of various unsubstantialities that technical scheme is carried out, or the most improved will
Design and the technical scheme of the present invention directly apply to other occasion, all within protection scope of the present invention.
