Description

Technical Field

[0001] The utility model belongs to the field of automobiles, and particularly relates to a fixing tooling, a fixing system and a flexible shaft friction force testing system. Background Technique

[0002] In recent years, with the rapid development of the automobile industry, vehicle comfort has also become an important direction for the development of automobile technology. An automobile sunroof is an important component for increasing the comfort of an automobile. A drain trough is a part of the frame of the automobile sunroof assembly. The drain trough contains a track for driving the operation of the automobile sunroof, and a flexible shaft is placed in the track in the drain trough. When the automobile sunroof operates, the flexible shaft is driven to move by a motor, thereby indirectly driving the movement of the sunroof glass to complete the actions of opening and closing the window. When the flexible shaft moves, it will generate frictional force with the track. In the research and development of automobile sunroofs, the frictional force of the flexible shaft is one of the important indicators for judging whether a sample is qualified. Therefore, it is very necessary to test the frictional force of the flexible shaft.

[0003] In the prior art, when testing the frictional force of a flexible shaft, the flexible shaft is installed in the track of the drain trough, and the drain trough is manually fixed on the test platform, keeping the drain trough fixed in the vertical direction, and then the fixed drain trough is placed on a tensile machine to test the frictional force of the flexible shaft. The manual fixing method in the prior art has the following problems:

[0004] (1) The position of the drain trough cannot be accurately adjusted, and the actual installation state of the drain trough, such as keeping it vertical, cannot be simulated.

[0005] (2) It cannot be guaranteed that the position of the drain trough remains unchanged during the test process.

[0006] (3) The direction of the flexible shaft cannot be kept parallel to the track.

[0007] It can be seen that the manual fixing method will produce large errors. In view of this, a fixing tooling that can accurately adjust the position of the drain trough and the relative position between the flexible shaft and the track is needed. Summary of the Invention

Please refer to Figure 1-2 , the fixing tooling 11 includes a first fixing member 111, a second fixing member 112, a third fixing member 113 and a first locking member 114. The first fixing member 111 includes a first track 1111, and the third fixing member 113 includes a first screw 1131, a stud 1132, a cavity 1133 and a second screw 1134.

[0036] In this embodiment, the first fixing member 111 is arranged vertically, the second fixing member 112 is arranged horizontally, the third fixing member 113 is arranged longitudinally, and the first track 1111 is also arranged vertically. The longitudinal direction is perpendicular to the vertical direction and the horizontal direction.

[0037] In this embodiment, the first fixing member 111 is movably connected to the second fixing member 112. The second fixing member 112 is installed on the first track 1111 and moves along the first track 1111. Specifically, when the second fixing member 112 moves to a suitable position, the second fixing member 112 is fixed to the first track through the first locking member 114.

[0038] In this embodiment, the third fixing member 113 is fixed to the second fixing member 112. Specifically, the third fixing member 113 is detachably connected to the second fixing member 112. Therefore, the number of the third fixing members 113 can be flexibly set according to actual situations, making it more convenient to use. Specifically, the cavity 1134 is fixed to the second fixing member 112. When the stud 1133 moves to a suitable position in the cavity 1134, the stud 1133 is fixed to the cavity 1134 through the second screw 1132.

[0039] In this embodiment, the drain trough 2 is fixed to the third fixing member 113. Specifically, the drain trough 2 is fixed to the third fixing member 113 through the first screw 1131.

[0040] In this embodiment, the horizontal axis coordinate of the drainage trough 2 is adjusted by horizontally moving the first fixing member 111; the vertical axis coordinate of the drainage trough 2 is adjusted by vertically moving the second fixing member 112; the third fixing member 113 longitudinally expands and contracts to adjust the longitudinal axis coordinate of the drainage trough 2. Specifically, the longitudinal axis coordinate of the drainage trough 2 is adjusted by the expansion and contraction of the stud 1133 in the cavity 1134.

[0041] In this embodiment, by adjusting the positions of the first fixing member 111, the second fixing member 112, and the third fixing member 113, the drainage trough 2 is adjusted to a suitable position, and the friction between the flexible shaft 3 and the drainage trough 2 is tested.

[0042] Embodiment Two:

[0043] This embodiment provides a fixing system 1 for fixing the drainage trough 2. Please refer to Figures 3-5 , the fixing system 1 includes four fixing tools 11 as described in Embodiment One. The specific structure of the fixing tool 11 is as described in Embodiment One and will not be elaborated here. In other embodiments of the present invention, the fixing system 1 only needs to include at least three fixing tools 11 to meet the requirements, and the number of the fixing tools can be set according to the actual situation.

[0044] In this embodiment, the fixing system 1 further includes a second track 12 and a second locking member. The second track 12 is horizontally arranged, and the first fixing member 111 is installed on the second track 12 and can move along the second track 12. Specifically, the fixing system includes two second tracks 12 arranged in parallel, and the first fixing member 111 is installed between the two second tracks 12. When the first fixing member 111 moves to a suitable position, the first fixing member 111 is fixed to the second track 12. Specifically, the first fixing member 111 and the second track 12 are detachable, so the number of the first fixing members 111 can be flexibly set.

[0045] Embodiment Three:

[0046] This embodiment provides a flexible shaft friction test system for detecting the friction between the flexible shaft and the guide rail of the drainage trough.

[0048] Embodiment Four:

[0049] This embodiment will elaborate on the usage process of the fixing system described in Embodiment 2 to further illustrate the technical solution of the present utility model.

[0050] In this embodiment, the steps of installing the drain trough using the fixing system are as follows:

[0051] (1) Initially adjust the position of the first fixing member 111 according to the position of the fixing holes of the drain trough 2;

[0052] (2) Install the flexible shaft 3 on the drain trough 2;
