随着汽车行业的迅猛发展,用于汽车的机械式电子油门踏板已逐渐被电子式油门踏板取代。电子式油门踏板通过电子信号来控制油门开合,具有高精度、低影响、长寿命等优点。电子式油门踏板分为悬挂式和踏板式两种。地板式踏板的驾驶舒适性要优于悬挂式油门踏板,且踏板式踏板在极限状态下(断裂)的安全性要高于悬挂式踏板。With the rapid development of the automobile industry, mechanical electronic accelerator pedals used in automobiles have gradually been replaced by electronic accelerator pedals. The electronic accelerator pedal controls the opening and closing of the accelerator through electronic signals, which has the advantages of high precision, low impact, and long life. Electronic accelerator pedals are divided into two types: suspension type and pedal type. The driving comfort of the floor pedal is better than that of the suspension accelerator pedal, and the safety of the pedal pedal in the extreme state (break) is higher than that of the suspension pedal.
在经济与科技不断发展的今天,汽车的造型和马力不断在革新,驾驶舒适性要求也越来越高。汽车行驶过程中油门踏板的位置由人脚控制,遇到颠簸路面时,踏板位置便很难保持稳定,直接影响踏板输出电信号的稳定性,对驾驶汽车造成很大不便,同时也会增加驾驶员的驾车疲劳感,影响乘车舒适性。With the continuous development of economy and technology, the shape and horsepower of automobiles are constantly innovating, and the requirements for driving comfort are getting higher and higher. The position of the accelerator pedal is controlled by the human foot during the driving of the car. When encountering bumpy roads, the position of the pedal is difficult to maintain stable, which directly affects the stability of the pedal output electrical signal, causing great inconvenience to driving the car, and also increasing driving The driver’s driving fatigue affects the ride comfort.
电子油门踏板作为车辆加减速的载体,若能使电子油门踏板具有迟滞产生机构,在驾驶过程中始终保持稳定的迟滞效果,便于驾驶员很好地控制踏板位置,提高驾驶舒适性,同时降低驾驶员脚部的疲劳感,这也是间接性地提高了驾驶安全性,减少了交通事故的发生。The electronic accelerator pedal is the carrier of vehicle acceleration and deceleration. If the electronic accelerator pedal has a hysteresis generating mechanism, it will always maintain a stable hysteresis effect during driving, which is convenient for the driver to control the pedal position, improve driving comfort, and reduce driving The fatigue of the feet of the driver also indirectly improves driving safety and reduces the occurrence of traffic accidents.
发明内容Summary of the invention
为了解决上述技术问题,本发明提供一种具有迟滞效应的踏板式电子油门踏板,通过在踏板式电子油门踏板上增加迟滞产生机构,在驾驶过程中产生稳定的迟滞效果,方便驾驶员很好地控制踏板位置,提高驾驶舒适性。In order to solve the above technical problems, the present invention provides a pedal-type electronic accelerator pedal with a hysteresis effect. By adding a hysteresis generating mechanism to the pedal-type electronic accelerator pedal, a stable hysteresis effect is generated during driving, which is convenient for the driver. Control the pedal position to improve driving comfort.
为此,本发明采用的技术方案是:To this end, the technical solution adopted by the present invention is:

The foot pedal is hinged with the bottom plate through a pedal shaft, the bottom of the foot pedal is provided with a supporting lug, and the upper shaft of the supporting lug is provided with a sensor shaft, The roller part is installed between the pedal and the bottom plate through the sensor shaft. The roller part drives the sensor shaft to rotate clockwise or counterclockwise. During the rotation, the roller of the roller part rolls and supports the upper side of the bottom plate; the sensor shaft is provided with hysteresis mechanism.
进一步地,所述迟滞机构包括第一阻尼片、第二阻尼片、压簧、垫片及螺钉;传感器轴 的第一端伸出脚踏板支耳,第一阻尼片活动穿过传感器轴的第一端固定安装在脚踏板支耳的外侧面上,第二阻尼片穿过传感器轴的第一端通过卡合结构与传感器轴连接,第二阻尼片随传感器轴同步转动且可沿传感器轴轴向滑动;第一、第二阻尼片相对的两端面设有相适配的旋转凸台,在初始状态下两旋转凸台嵌合成一体,两台面完全贴合,在踩踏脚踏板时两旋转凸台分离,两凸台的顶面摩擦转动连接;第二阻尼片的另一端面设有凹槽,压簧安装在所述凹槽内,螺钉依次穿过垫片、压簧紧固在传感器轴的第一端的端面上,压簧的一端抵靠凹槽,另一端抵靠垫片。Further, the hysteresis mechanism includes a first damper sheet, a second damper sheet, a compression spring, a washer and a screw; the first end of the sensor shaft extends out of the foot pedal lug, and the first damper sheet moves through the sensor shaft The first end is fixedly installed on the outer surface of the foot pedal support lug. The second damper plate passes through the first end of the sensor shaft and is connected to the sensor shaft through a snap-fit structure. The second damper plate rotates synchronously with the sensor shaft and can move along the sensor. The shaft slides in the axial direction; the opposite ends of the first and second dampers are provided with matching rotating bosses. In the initial state, the two rotating bosses are fitted into one body, and the two surfaces are fully fitted. When stepping on the pedal The two rotating bosses are separated, and the top surfaces of the two bosses are connected by friction and rotation; the other end of the second damping plate is provided with a groove, a compression spring is installed in the groove, and the screw passes through the washer and the compression spring is tightened in turn On the end surface of the first end of the sensor shaft, one end of the compression spring abuts against the groove, and the other end abuts against the gasket.

在汽车行驶中,驾驶员脚部对脚踏板2施加外力,脚踏板2绕踏板轴9转动,脚踏板下压对滚轮部件18施加向前滚动的力,滚轮部件18将带动传感器轴发生转动,在脚踏板下压的压力作用下,第一阻尼片推动第二阻尼片23沿着传感器轴10向外侧移动,第二阻尼片的旋转凸台23-3沿第一阻尼片22的旋转凸台22-3逐渐爬升,直至第一阻尼片的凸台顶面22-3-1与第二阻尼片的凸台顶面23-3-1接触,传感器轴10随之发生转动,第二阻尼片23随着传感器轴一起转动,第二阻尼片向外侧移动对压簧24产生挤压,压簧变形对第二阻尼片23产生轴向正压力,两个旋转凸台在正向压力作用下相互摩擦,从而产生摩擦阻尼力,且阻尼力的力值曲线与踏板力可保持相同的曲线,使得驾驶过程更平稳。When the car is running, the driver's feet apply external force to the pedal 2, the pedal 2 rotates around the pedal axis 9, and the pedal is pressed down to exert a forward rolling force on the roller member 18, and the roller member 18 will drive the sensor axis When the rotation occurs, under the pressure of the foot pedal, the first damper pushes the second damper 23 to move outward along the sensor shaft 10, and the rotation boss 23-3 of the second damper moves along the first damper 22 The rotating boss 22-3 gradually climbs until the top surface 22-3-1 of the first damper plate contacts with the top surface 23-3-1 of the second damper plate, and the sensor shaft 10 rotates accordingly. The second damping plate 23 rotates along with the sensor shaft. The second damping plate moves outward to squeeze the compression spring 24. The deformation of the compression spring generates an axial positive pressure on the second damping plate 23. The two rotating bosses are in the positive direction. Under the action of pressure, the friction damping force is generated, and the force value curve of the damping force and the pedal force can maintain the same curve, making the driving process more stable.
为使阻尼力的力值曲线与踏板力可保持相同的曲线,特选用圆柱压簧24,其能够产生一个线性的力值。In order to keep the force curve of the damping force and the pedal force the same curve, the cylindrical compression spring 24 is specially selected, which can generate a linear force value.
为保证阻尼力递增的线性,避免出现剧增的想象,对旋转凸台梯度进行如下设计:In order to ensure the linear increase of the damping force and avoid the imagination of sudden increase, the gradient of the rotating boss is designed as follows:
假设踏板行程角为α,传感器旋转角为β,第二阻尼片与传感器轴同步转动,则第二阻尼片的旋转角度与传感器旋转角度相同。Assuming that the pedal stroke angle is α, the sensor rotation angle is β, and the second damper plate rotates synchronously with the sensor shaft, the rotation angle of the second damper plate is the same as the sensor rotation angle.
根据本发明的油门踏板的结构特征建立本发明油门踏板的连杆旋转结构,如图12所示,则踏板行程角α与传感器旋转角为β的关系式如下:According to the structural characteristics of the accelerator pedal of the present invention, the connecting rod rotation structure of the accelerator pedal of the present invention is established. As shown in FIG. 12, the relationship between the pedal stroke angle α and the sensor rotation angle β is as follows:
α′=(180°-γ)α′=(180°-γ)
g=c×sinα′=c×sin(180°-γ)g=c×sinα′=c×sin(180°-γ)
f=a×sin(α-α )=a×sin(α-(180°-γ)) f=a×sin(α-α )=a×sin(α-(180°-γ))
β′=90°-(α-α )=90°-(α-(180°-γ)) β′=90°-(α-α )=90°-(α-(180°-γ))
g+f=b×cos(β-β′)g+f=b×cos(β-β′)
Therefore
c×sin(180-γ)+α×sin(α-(180°-γ))=b×cos(β-(90°-(α-(180°-γ))))c×sin(180-γ)+α×sin(α-(180°-γ))=b×cos(β-(90°-(α-(180°-γ))))
则计算出阻尼片2旋转角度与脚踏板旋转角度关系如下:The relationship between the rotation angle of the damper 2 and the rotation angle of the pedal is calculated as follows:
β=270°-α-γ+arccos((α×sin(α+β-180°)+c×sin(180°-γ))/b)β=270°-α-γ+arccos((α×sin(α+β-180°)+c×sin(180°-γ))/b)
已知踏板行程角α为18度,传感器旋转角β为60度,在60°范围内,第一阻尼片与第二阻尼片需旋转产生1mm的高度差,带入如上公式得出梯度数据如下:It is known that the pedal stroke angle α is 18 degrees, and the sensor rotation angle β is 60 degrees. Within the range of 60°, the first damper and the second damper need to rotate to produce a height difference of 1mm. The gradient data is obtained by the above formula. :
