Foldable-screen mobile phones can be opened like tablet computers and folded like mobile phones, which are easy to carry and can provide consumers with more experiences, such as playing games and watching videos. Major manufacturers have all launched foldable-screen mobile phones.
[0003] Folding-screen mobile phones of the folding type inevitably need to use rotating shaft assemblies. In the prior art, rotating shaft assemblies contain a large number of components, and therefore, the assembly cumulative error thereof can be relatively large. Foldable electronic devices equipped with rotating shaft assemblies with large assembly cumulative error can cause the foldable electronic devices in a flat state to exhibit a large virtual position, so that a large planar displacement can occur between one plate and another plate of the foldable electronic device in the flat state, which seriously affects the user experience.
[0004] Currently, there is no detection device capable of detecting the virtual position of a rotating shaft assembly in a flat state, so that the quality of rotating shaft assemblies leaving the factory cannot be guaranteed. SUMMARY

[0006] To solve the above technical problem, the present application adopts the technical scheme of a virtual position detection device for a rotating shaft assembly in a flat state, which is used to detect the virtual position of a rotating shaft assembly in a flat state. One side of the rotating shaft assembly is connected with a first mounting member, and the other side of the rotating shaft assembly is connected with a second mounting member. The virtual position detection device comprises a rack, a fixing position, a fixing mechanism, a detection position, and a pushing mechanism. The fixing position and the detection position are arranged side by side. The fixing mechanism is used to fix the first mounting member in the fixing position. The pushing mechanism is used to push the second mounting member in the detection position. The pushing mechanism comprises an X-axis pushing assembly and a Y-axis pushing assembly. The X-axis pushing assembly comprises an X-axis linear drive member and an X-axis pushing block connected with each other. An X-axis distance sensor is arranged on the X-axis pushing block. The detection path of the X-axis distance sensor faces the detection position. The Y-axis pushing assembly comprises a Y-axis linear drive member and a Y-axis pushing block connected with each other. A Y-axis distance sensor is arranged on the Y-axis pushing block. The detection path of the Y-axis distance sensor faces the detection position. The number of X-axis pushing assemblies is at least two. Part of the detection position is located between the two X-axis pushing assemblies. The number of Y-axis pushing assemblies is at least two. Part of the detection position is located between the two Y-axis pushing assemblies.
[0007] The beneficial effect of the present application is that after the fixing mechanism fixes the first mounting piece connected with the rotating shaft assembly, the pushing mechanism pushes the second mounting piece connected with the rotating shaft assembly along the X-axis direction / Y-axis direction, the position change distance of the second mounting piece in the X-axis direction / Y-axis direction is detected by the X-axis distance sensor / Y-axis distance sensor before and after pushing, so that the virtual position size of the rotating shaft assembly in the flat state is obtained, and whether the rotating shaft assembly product is a defective product is judged, thereby ensuring the quality of the rotating shaft assembly product.

Since the structure of the shaft assembly 11 is relatively small, in order to facilitate testing, it is necessary to connect the shaft assembly 11 with other structures to form a test body 1 for convenient testing. Specifically, one side of the shaft assembly 11 is connected with a first mounting member 12, and the other side of the shaft assembly 11 is connected with a second mounting member 13, that is, the first mounting member 12, the shaft assembly 11 and the second mounting member 13 are connected in sequence to form the test body 1, as shown in Figure 3 Optionally, the first mounting member 12 and the second mounting member 13 are respectively screwed with the shaft assembly 11.
[0040] From a certain point of view, the first mounting member 12 and the second mounting member 13 can also be considered as part of the shaft assembly flat state virtual position detection jig. Of course, the first mounting member 12 and the second mounting member 13 are not essential components of the shaft assembly flat state virtual position detection jig. For example, when the folding electronic product carrying the shaft assembly 11 is detected by using the shaft assembly flat state virtual position detection jig, the first mounting member 12 and the second mounting member 13 are not needed.
[0041] In this embodiment, the first mounting component 12 and the second mounting component 13 are respectively a grid structure. In other embodiments, the first mounting component 12 / the second mounting component 13 can also be a plate structure.

[0045] The middle area of the support table 21 is provided with an avoiding groove 211 for avoiding the pivot assembly 11.
