Problems solved by technology

The traditional pedal arm is usually one arm, which requires a lot of Z-direction layout space in the car. New energy vehicles need to arrange the head-up display, so the Z-direction space is very small, and there are often problems that the layout cannot be accommodated.

Embodiment 1

[0021] Such as figure 1 , figure 2 In the shown embodiment, a variable lever ratio brake pedal with an angle sensor for a new energy vehicle includes a pedal base 1 and a pedal arm 4, the pedal arm 4 is rotatably connected to the pedal base 1, and the pedal base 1 is provided with a first rotating shaft 10, and the upper end of the pedal arm 4 is rotatably matched with the first rotating shaft 10. The pedal base 1 is also provided with a swing arm 5 , the pedal base 1 is provided with a second rotating shaft 11 parallel to the first rotating shaft 10 , and the middle part of the swing arm 5 is in rotation with the second rotating shaft 11 . The pedal base 1 is provided with a brake light switch 2 , and the pedal arm 4 is provided with an action end 3 acting on the brake light switch 2 .

[0022] combine figure 2 As shown, a hinged connecting rod 12 is provided between the pedal arm 4 and the swing arm 5, so that the swing arm 5 is driven to rotate when the pedal arm 4 rot...

Embodiment 2

[0026] The difference between embodiment 2 and embodiment 1 is that, as image 3 As shown, the pedal base 1 is provided with an air blowing pipe 13 below the swing arm 5, the air outlet of the air blowing pipe 13 faces the angle sensor, the middle part of the air blowing pipe 13 is provided with a valve body 14, and the valve body 14 is provided with a control air blowing pipe 13 through The broken spool 16 and the spring 15 that drives the spool 16 to reset. One end of the valve body 14 is provided with an air inlet, and the other end is provided with an air outlet, and the air inlet and the air outlet are respectively communicated with the blowing pipe 13 . The valve core 16 is provided with a flow hole 16a. When the valve core 16 is opened, the flow hole 16a connects the air inlet and the air outlet, and when the valve core 16 is closed, the air inlet and the air outlet are blocked.

[0027] In the actual operation process, when the driver steps on the pedal, the pedal arm...

Abstract

The invention discloses a variable-lever-ratio brake pedal with an angle sensor and for a new energy vehicle. The brake pedal comprises a pedal base and a pedal arm rotationally connected to the pedalbase. The pedal base is provided with a swing arm. A connecting rod is hinged between the pedal arm and the swing arm so that the pedal arm can drive the swing arm to rotate when rotating. The anglesensor for detecting the rotating angle of the swing arm is arranged on the pedal base. The variable-lever-ratio brake pedal with the angle sensor and for the new energy vehicle reduces the Z-directional space occupation and meanwhile conveniently outputs pedal position signals.

Description

technical field [0001] The invention belongs to the field of braking of new energy vehicles, in particular to a variable lever ratio brake pedal with an angle sensor for new energy vehicles. Background technique [0002] The brake pedal is the pedal that limits the power in the vehicle, that is, the pedal of the foot brake (service brake). The brake pedal is used to slow down and stop. It is one of the five major controls for car driving and is used very frequently. The traditional pedal arm is usually one arm, which requires a large Z-direction space in the car. New energy vehicles need to arrange the head-up display, and the Z-direction space is very small, and there are often problems that the layout cannot be accommodated. Traditional brake pedals cannot output pedal position signals, but new energy vehicles need pedal position signals for energy recovery control and automatic braking intensity control. Contents of the invention [0003] The present invention aims to ...
