Problems solved by technology

At present, the method of comparative observation is generally used, which requires manpower to find out the specified boundary range for each test.
This not only causes a waste of human resources, but also easily causes measurement deviations through the observation of human eyes. In addition, it cannot realize real-time monitoring of displacement changes.

Embodiment Construction

[0023] like figure 1 As shown, a displacement tracking test device for a fixed point on a seat belt of a car seat includes a first camera 2 set above the tested seat 1, a second camera set on the left or right side of the tested seat 1 3. Both the first camera 2 and the second camera 3 are fixed on the bracket 6 . The first camera 2 is used to shoot the forward and backward displacement images (X axis) of the fixed point 11 on the safety belt (hereinafter referred to as the fixed point on the safety belt) arranged on the seat 1 under test, and the second camera 3 is used to take pictures on the safety belt. For the vertical displacement image (Y axis) of the fixed point 11, the images taken by the first camera 2 and the second camera 3 are transmitted to the computer 5 in real time through the image acquisition card 4 for processing.

[0024] A displacement tracking test method of a fixed point on a car seat safety belt, comprising the following steps:

Abstract

The invention provides a displacement tracking test device and method of fixing points on an automobile seat belt. The device comprises two cameras fixed on a support, one camera is arranged above a seat to be tested, and the other camera is arranged on the left side or the right side of the seat to be tested. The two cameras are connected with a computer through image capturing cards respectively. The computer comprises an image receiving module, a corresponding relation determining module, a coordinate extraction module, a displacement computing module and a comparative judgment module. The invention further provides the displacement tracking test method of the fixing points on the automobile seat belt. By means of the displacement tracking test device and method of the fixing points on the automobile seat belt, real-time tracking of displacement change conditions of the fixing points on the automobile seat belt under stress can be achieved, the displacement change generated after the stress is applied to the fixing points on the automobile seat belt is tested precisely, and the current situations of manual prescribed boundary correcting and visual observation are changed, so that manpower cost is saved, and measurement accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of strength testing of fixed points of safety belts of automobile seats, in particular to a displacement tracking test device and method for fixed points of safety belts of automobile seats. [0002] Background technique [0003] At present, the fixed points of the seat belts of some car seats are set on the car seat. This arrangement requires a high strength of the seat frame, and the seat frame must have strong impact resistance so that it can Guaranteed to protect the occupants well. The GB regulations require that the displacement of the fixed point on this type of safety belt cannot exceed the specified boundary range under the condition of force. At the same time, the new regulations of GB14167-2013 require that the rear front-facing seats of M1 and M2 cars less than 3.5T must be equipped with three-point seat belts, which increases the probability that the fixed points on the seat belts are set on t...
