Pressure sensing device for simulating vehicle brake pedal

Abstract

The invention discloses a pressure sensing device for simulating a vehicle brake pedal. The pressure sensing device comprises a pressure sensor, a spring series body and a limiting piece. The pressuresensing device is fixed on an extension line of a traveling path when a brake pedal is stepped. The spring series body is formed by connecting at least two springs in series. The limiting piece is used for limiting the compression deformation quantity of a part of springs in the spring series body. The spring series body is arranged between the brake pedal and the pressure sensor, and the two ends of the spring series body abut against the brake pedal and the pressure sensor respectively. According to the pressure sensing device for simulating the vehicle brake pedal, the spring series body formed by connecting at least two springs in series is arranged between the brake pedal and the pressure sensor, the two ends of the spring series body abut against the brake pedal and the pressure sensor respectively, and meanwhile, the limiting piece is further arranged to limit the compression deformation quantity of a part of the springs in the spring series body, the stroke change trend that atraditional brake pedal is light in the front and tight in the rear during braking can be well simulated, and the user experience feeling is better.

Problems solved by technology

[0002] In simulated racing games, simulated driving teaching, or simulated vehicle toys, the technical core of the simulated brake pedal is to use sensors to detect the stroke changes of the brake pedal. The commonly used sensors include: 1. Potential linear sensor / angle sensor, which is the most A simple pedal structure, which is transformed into the depth of the pedal position through the change of the linear sensor / angle sensor data; 2. The Hall sensor is essentially the same as the potentiometric linear / angle sensor in simulating the brake feeling of the vehicle, but Its working principle is non-contact induction, which has the best life and reliability; 3. Pressure sensor, which reflects the stroke change of the brake pedal by detecting the pressure received; 4. Hydraulic sensor, which has a higher real feeling of braking, but the structure is complex and more expensive

[0003] The analog brake pedal using the above-mentioned potentiometric sensor / angle sensor, Hall sensor and pressure sensor can basically only reflect the moving stroke of the brake pedal in a single linear manner, which is different from the traditional brake pedal that is loose at the front and tight at the back. The working state is not very consistent, the user cannot adapt immediately and cannot achieve a better experience of simulating real braking

Although the hydraulic sensor has good simulation performance, it has the disadvantage of high cost

Moreover, the above-mentioned various analog brake pedals all have the defect that users cannot selectively select their own braking force and braking force style according to their own preferences or game intensity.
