Embodiment Construction

[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but the scope of the present invention will not be limited.

[0018] as attached figure 1 As shown, a kind of automobile door closing force testing device of the present invention is made up of seven parts: handle 1, strain gauge force sensor 2, connecting plate 3, magnetic base 4, magnetic shielding plate 5, connecting block 6 and capacitive displacement sensor7.

[0019] Handle 1 is made up of two parts, and the upper end is a plastic part, and the lower end is a metal part. The shape of the strain gauge force sensor 2 is S-shaped, one end is connected with the lower metal part of the handle 1 through a screw, and the other end is connected with the connecting plate 3 through a screw, and the strain gauge force sensor 2 is connected with a force digital display to display the closing force of the door the size of. The connecting plate 3 is...

Abstract

A device for testing door close force of automobile is controlled by computer, it applies S-shape strain type of force test transducer and capacity type of displacement transducer to measure force and displacement as well as applies serial interface to input force displacement signal to portable computer for realizing real time data collection and communication . The device not only can realize test of door close force but also can realize test of door close displacement.

Description

technical field [0001] The invention relates to an automobile door closing force test device, which can realize the test of the closing force of the car door and the closing displacement of the car door, and belongs to the technical field of precision testing. Background technique [0002] With the continuous development of science and technology, the various performance indicators of automobiles (such as power, economy, comfort, passability, handling stability, safety and reliability, etc.) are also constantly improving. Become one of the important standards to measure the quality of the car. The closing force of the car door is an important index to measure the quality of the car door, but the actual measurement problem of the closing force has not been solved in China, especially the characteristics of the closing force of the door during the closing process is still lack of practical detection means. Therefore, it is necessary to develop a test device for the closing fo...
