Description

Technical Field

[0001] The invention belongs to the field of glass tension force detection equipment, and in particular, the invention relates to a load mechanism for glass lifter detection. Background Art

[0002] The car door glass lifter is assembled from a series of parts. During the use of the car door glass lifter, you may encounter problems such as increased resistance and uneven running speed. These problems may be caused by large glass lifting resistance, lifter damage, guide rail installation position deviation, etc. By testing the pressure of the glass lifter, you can prevent people from being pinched and prevent the glass or lifter itself from being damaged due to excessive mechanical pressure.

[0003] During the rising process of the glass lifter, weights of equal weight requirements are added to replace the friction of the actual movement of the window. In an ideal state, when the window is in operation: the gravity of the window glass + the friction of operation = the gravity of the weight + the gravity of the auxiliary mechanism (the gravity of the window glass = the gravity of the auxiliary mechanism). Since the process of using and not using weights during the operation of the lifter generates noise and jitter, the accuracy of the noise detection in the quiet room is affected; the process of using and not using weights during the operation of the lifter will cause overweight and weightlessness, which will lead to inaccurate detection results of parameters such as current; during the conversion process of using and not using weights, the weights are easy to fall, which may cause serious mechanical failure; the conversion process of using and not using weights seriously affects the production rhythm; the original mechanism lifter uses and does not use weights during operation, and the counterweight is placed on the load mechanism through the counterweight cylinder. This process will cause the load mechanism to shake and collide, etc. The noise and jitter generated in this process will affect the detection effect. Summary of the invention

DETAILED DESCRIPTION

[0022] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0033] Functions and Effects of the Embodiments

[0034] One end of the wire rope is hung on one end of the glass lifter through a hook, and the other end of the wire rope first passes around the roller 204 and then passes around the first pulley 207 and finally connects to the weighing sensor 208.
