Manufacturing method of automobile pedal load cell detection device

The utility model relates to the technical field of automobile pedals, in particular to an automobile Load Cell Pedals detection device that monitors the pedal rotation angle and the force relationship, optimizes the pedal structure, and improves comfort.

Background technique:

The accelerator pedal is a device that controls the fuel supply on the internal combustion engine. When the vehicle is running, the driver controls the amount of engine air intake by controlling the amount of pedaling, thereby controlling the engine speed. There are two types of accelerator pedals, "floor type" and "suspension type", and there is no difference in their essential functions. The floor pedal is located at the bottom of the pedal, so the sole of the foot can be stepped on, and the pedal itself is also a fulcrum. The calf and ankle can control the pedal more easily, which correspondingly improves the accuracy of the pedal control under the foot and reduces the sense of fatigue. With the manual transmission, the floor pedal can easily perform technical actions; on the contrary, the suspension accelerator pedal has a relatively simple (thin) lower structure because the shaft is located at the top of the bracket, so it also makes its pedaling method lighter. Moreover, the pedal bracket can be made into iron rods in the design, so the cost can be saved to a large extent, so the general manufacturers prefer to use this kind of pedal.

Compared with the floor pedal, the suspension accelerator pedal can only provide a fulcrum for the forefoot, so driving the calf for a long time will be more rigid, which is the suspension pedal that most people complain about is tired after driving for a long time, and it causes it Its control accuracy is not as good as the floor pedal, and it can't make movements easily. From the perspective of vehicle design, suspension accelerator pedals are generally used for tall SUVs. This is because the instrument panel has a higher installation position and a higher sitting posture. The use of floor pedals may not be suitable for all driving groups. Will lead to unreasonable ergonomics.

The force exerted on the car pedal when stepping on affects the comfort of the operator. A comfortable pedal is not easy to cause fatigue, labor saving, and effective. A car pedal that monitors the pedal angle and force relationship, optimizes the pedal structure, and improves comfort is needed. Force detection device.
