Technical Field

Background

The combined switch for automobile is a kind of set of switches for electric appliances of automobile, it is installed on the steering column of automobile and is a device composed of more than two switches for controlling the light, signal and controlling electric appliances of automobile. As shown in figure 1, the internal structure of the automobile combined switch handle generally adopts a groove type structure, the switch handle 1 is shifted through a rotating shaft 4 through a guide block 2 and is reset through a torsion spring 3, and a guide groove 21 is arranged at the connecting part of the guide block 2 and the switch handle 1. The handle force characteristic of the combined switch is a factor to be considered when evaluating a vehicle, and the handle force characteristic reflects the characteristics of a product structure and the stability of a product process besides giving an operation feeling to a driver. Therefore, the test research aiming at the operating force of the automobile combined switch handle is helpful for product designers to analyze the product defects and improve the product structure and process.

According to the regulations, the torque required for switching the combined switch handle from one gear to another gear is in accordance with the regulations of the design documents. The difference between the left and right transfer torques should be no more than 25% of any one (left or right) of the shift transfer torques. The internal structure of the combined switch handle determines that the approximate state of the operating force required by the handle is a stress application process and a critical state in the switching process of each gear, and then the handle enters a falling process after the stress application process, and an impact process can occur after the handle falls back. Therefore, the operation force of the automobile combined switch handle has great influence on the product structure and the process.

The design drawing of the combined switch defines the operation force value and the operation direction of the handle, and the general operation direction is 90 degrees to the axis of the handle of the combined switch. The traditional handle operating force test is carried out manually by adopting a pressure sensor or a handheld push-pull dynamometer, the operating force is applied in a direction which is approximately 90 degrees to the axis direction of the combined switch handle, and the maximum value of the operating force is recorded by the pressure sensor or the handheld push-pull dynamometer in the force application process. The testing mode has certain defects and limitations, the stability of the force application direction cannot be measured and ensured in the manual force application process, the force application direction is continuously changed due to the fact that the handle is not in a fixed position in the force application process but continuously rotates around the axis, and the actual measuring result has larger deviation from the actual operating force value. And different operators have large difference of obtained measurement values due to operation habits and skills, analysis and processing are difficult to carry out, the measurement result cannot simply and intuitively draw the relation between the gears and the operation force, and the workload of later analysis and processing is increased.
