Abstract
Description
Technical Field
[0001] The invention relates to the technical field of window lifter testing tooling, and more particularly to a tooling structure for providing a constant load to a glass lifter guide rail. Background Art
[0002] The window lifter assembly is a functional component used to realize the lifting and lowering of automobile windows. The performance of the window lifter assembly plays a decisive role in the lifting and lowering speed, closing force, anti-theft performance, etc. Due to the differences in glass size and rubber strip performance of different models, there are obvious differences in the loads between different windows, which leads to the need to select the power parameters of the window lifter assembly, such as load and operating speed under the load. This is related to the performance of the motor used, the diameter of the rope pulley, the transmission efficiency of the lifter assembly mechanism, etc., so it will be difficult to effectively adapt when selecting through calculation.
[0003] Based on this, it is necessary to design a tooling or component that can provide a constant load to the window lifter assembly to simulate the load of the actual vehicle glass and rubber strips, so as to comprehensively consider all the factors mentioned above for selection.
[0004] However, when actually providing loading, it was found that because the window lifter assembly needs to cater to the curvature of the actual door glass, the guide rail of the window lifter assembly also has a curvature, rather than a linear guide rail. Therefore, it is difficult to use a linear guide rail to stabilize the weight and apply it to the force position of the assembly guide rail; and if the weight is directly applied to the force position on the guide rail, since the weight is not stabilized, the load change caused by the swing of the weight adds variables to the verification, which makes it difficult for the implemented simulation test to meet the actual state, affecting the accuracy of the selection, and needs to be improved. Summary of the invention
[0005] In view of this, the purpose of this application is to provide a tooling structure for providing a constant load to the glass lifter guide rail, so as to significantly improve the accuracy of the simulated load test of the window lifter. The specific scheme is as follows:

[0008] Preferably: the guide body includes two side guide bodies that are slidably connected to the corresponding vertical guide bodies up and down, and a sliding guide body that is slidably connected to the horizontal guide body left and right; the two horizontal guide shafts are distributed up and down or front and back, and both ends are plugged and fixed to the corresponding side guide bodies; the lifting ring is connected and fixed to the bottom of the side guide body.

[0017] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0018] like Figure 1 As shown, a tooling structure for providing a constant load to a glass lifter guide rail includes a plurality of guide shafts respectively arranged along three-dimensional X, Y and Z axes, a plurality of guide bodies for axial movement along the corresponding guide shafts, a window gusset plate 6 and a lifting ring 7.
[0019] In order to achieve the tooling structure for providing a constant load to the glass lifter guide rail to stably support the glass lifter, thereby improving the accuracy of the simulated load test based on the constant load, the lifting ring 7 is fixed to the bottom of the guide body and used to connect the counterweight wire rope. The counterweight wire rope can be purchased from the market and will not be described in detail here. At the same time, the window gusset 6 is used to simulate the gusset structure at the bottom of the window, and is connected and assembled with the gusset of the lifter assembly to transmit the assembly power.
[0020] It should be mentioned that the guide shaft includes two vertical guide shafts 1 arranged along the Y-axis direction, two horizontal guide shafts 2 arranged along the X-axis direction, and a vertical guide shaft 3 arranged along the Z-axis direction. The vertical guide shaft 1, the horizontal guide shaft 2, and the vertical guide shaft 3 are connected in sequence, and further provide a movable operation space along the three-dimensional X, Y, and Z-axis directions, so that the tooling structure for providing a constant load to the glass lifter guide rail has the effect of running smoothly with minimal loss at a position where the force changes. At the same time, the horizontal guide shaft 2 is used to connect multiple guide bodies. Among them, the guide body includes two side guide bodies 4 that are respectively connected to the corresponding vertical guide body up and down and a sliding guide body 5 that is connected to the horizontal guide body left and right. In the embodiment of the present application, the two horizontal guide shafts 2 are distributed up and down or front and back, and the two ends are plugged and fixed with the corresponding side guide body 4, so that the two side guide bodies 4 and the sliding guide body 5 form a stable vertical connection structure to provide a stable support effect. As for the lifting ring 7 connecting the counterweight wire rope, in order to improve the fixing stability of the lifting ring 7 and avoid the difference in downward pulling force between the two side guide bodies 4 when the lifting ring 7 is connected to the counterweight wire rope, a connecting plate 9 is provided between the bottoms of the two side guide bodies 4, and the lifting ring 7 is fixed to the middle part of the bottom of the connecting plate 9, so as to achieve the purpose of uniform and balanced force, and further enable the tooling structure for providing a constant load to the glass lifter guide rail to have the effect of running smoothly with minimal loss at the position where the force changes, and achieve the purpose of significantly improving the accuracy of the simulated load test.
[0021] like Figure 1 As shown, the vertical guide shaft 3 is vertically inserted into the sliding guide body 5, and the rear end is connected and fixed to the window gusset 6. The axis of the vertical guide shaft 3 is perpendicular to the vertical guide shaft 1 and the horizontal guide shaft 2 at the same time, so that the vertical guide shaft 3, the vertical guide shaft 1 and the horizontal guide shaft 2 form a linear guide rail corresponding to the three-dimensional X, Y and Z axis directions, so that the tooling structure for providing a constant load to the glass lifter guide rail is applied to the window lifter assembly with minimal loss.
[0022] It should be noted that a hole is opened in the middle of the rear end of the side guide body 4 and is U-shaped, and both upper and lower ends of the side guide body 4 are provided with linear bearings 8 for sleeved on the vertical guide shaft 1. At the same time, in order to improve the smoothness of movement between the sliding guide body 5 and the horizontal guide shaft 2 and the smoothness of movement between the vertical guide shaft 3 and the sliding guide body 5, a linear bearing 8 for sleeved on the vertical guide shaft 3 is provided on the sliding guide body 5, and two linear bearings 8 respectively sleeved on the corresponding horizontal guide shafts 2 are provided on the horizontal guide shaft 2.
[0023] A performance test was conducted on the tooling structure for providing a constant load to the glass lifter guide rail in the embodiment of the present application. The test was conducted in the following manner:
[0024] The actual vehicle was tested with an average load of 101.6 N, and a simulated counterweight of 100 N was installed to monitor the actual load borne by the window gusset 6 during the entire operation phase. The test results are shown in Tables 1, 2 and 3 below.
[0025] Table 1 Results of the first load test
[0026]
[0027] Table 2 Results of the second load test
[0028]
[0029]
[0030] Table 3 Results of the third load test
[0031]
[0032] Based on the above three load test results, it can be known that the three average loads of the embodiment of the present application are 97.10357143, the three average load differences are 1.03%, and the three average load fluctuations are 4.26%. Among them, the actual load loss is -2.90%, and the maximum load loss is -3.29%. It can be seen that the tooling structure for providing a constant load to the glass lifter guide rail in the embodiment of the present application
[0033] The actual load loss is controlled within 5%, and the loss can be compensated by adding simulated counterweights, such as increasing the counterweight mass to 103N, in order to achieve the purpose of further accurately testing the load value. At the same time, given that the average load difference of three consecutive load operations is controlled within 1.03%, it is better than the existing 2.10% load difference of real car doors. This is mainly due to the corresponding difference caused by the change in the resistance of the rubber strip after multiple operations of the real car door. And from Tables 1, 2 and 3 above, it can be seen that the load fluctuation level of the embodiment of the present application is low, with an average fluctuation of 4.26%, which has better stability than 8.22% of the real car, thereby meeting the simulated load design requirements in the development stage.
[0034] In summary, the present application provides a tooling structure for providing a constant load to a glass lifter guide rail, and the tooling structure for providing a constant load to a glass lifter guide rail has the following beneficial effects: by being installed and arranged at the force positions of the guide rail that change in three-dimensional directions, it is stably fixed between the force positions of the linear guide rail, so that the tooling structure for providing a constant load to the glass lifter guide rail can be applied to the window lifter assembly with minimal loss, so that the tooling structure for providing a constant load to the glass lifter guide rail has the effect of running smoothly with minimal loss at the position where the force changes, thereby significantly improving the accuracy of the simulated load test.
