Embodiment 1

[0055] After repeated tests and verifications, the applicant found that: in general, the connection between the steering wheel 1 and the clock spring 2 is as follows: the steering wheel 1 is provided with a mounting frame 12, the steering wheel 1 is connected with the male end of the connector 6, and the clock spring is connected. 2 is connected with the female end of the connector 6, the connection between the clock spring 2 and the steering wheel 1 is realized by the butt joint of the male end and the female end of the connector 6, and the connector 6 after the docking is located in the installation frame 12; 1 During the rotation process, the plug connector 6 will be driven to move in the installation frame 12. Ideally, it is expected that the plug connector 6 will always be in the center of the installation frame 12, but due to the actual assembly state, the clock spring 2 is installed on the steering column 3. , the steering wheel 1 is also installed on the steering column...

Embodiment 2

[0084] Embodiment 2 of the present application provides a method for testing the reliability of the connection between a steering wheel and a clock spring, and the testing method includes the following steps:

[0085] S1: Provide test system;

[0086] S2: Fix the steering column 3 on the vibration table 5;

[0087] S3: control the vibration table 5 to vibrate, drive the steering wheel 1 to rotate around the steering column 3 at the same time, and drive the clock spring 2 to rotate;

[0088] S4: collect the conduction signal of the connector 6;

[0089] S5: According to the conduction signal, determine whether the connector 6 is disconnected, and verify whether the preset assembly tolerance is qualified;

[0090] S6: If the conduction signal does not meet the conduction condition, it is judged that the connector 6 is disconnected, and it is determined that the preset assembly tolerance is unqualified;

[0091] S7: If the conduction signal satisfies the conduction condition, ...

Abstract

The invention relates to a system and method for testing connection reliability of a steering wheel and a clock spring, the steering wheel and the clock spring are connected through a connector clip according to a preset assembly tolerance, and the steering wheel and the clock spring are both installed on a steering column; the test system comprises a test box, a vibration table, a driving device, a detection device and a control device, and the vibration table is arranged in the test box and used for fixing the steering column; the driving device is connected with the steering wheel; the detection device is connected with the connector clip and is used for collecting a conduction signal of the connector clip; the control device is connected with the vibration table, the driving device and the detection device and used for controlling the vibration table to vibrate, controlling the driving device to drive the steering wheel and the steering column to rotate and driving the clock spring to rotate; and the control device is further used for judging whether the connector clip is disconnected or not according to the conduction signal and verifying whether the preset assembly tolerance is qualified or not.

Description

technical field [0001] The present application relates to the technical field of automobile testing, and in particular, to a system and method for testing the reliability of the connection between a steering wheel and a clock spring. Background technique [0002] The steering wheel is fixed on the steering column by a bolt, and the steering column transmits the torque on the steering wheel to the steering gear and drives the steering gear to work to control the driving direction of the car. The clock spring is a key electrical rotary connector used in the steering wheel of the automobile. It is mainly composed of a flexible flat cable, a relatively rotating rotor and a casing, a wiring harness (conductive lead wire) and a connector. It is generally installed under the steering wheel of the vehicle. During the left and right rotation of the steering wheel, the electrical components such as the front airbag and the horn switch can be reliably connected between the two relative...
