[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0019] Reference Figures 1 to 3 As shown, a hinge displacement detection device of the present invention includes: a bearing assembly 1, including a bearing seat 15, a first clamping member 13 and a second clamping member 18, the second clamping member 18 being connected to the bearing seat 15, the bearing seat 15 having a bearing space for accommodating the hinge, the first clamping member 13 being movable toward the second clamping member 18, the bearing space being located between the first clamping member 13 and the second clamping member 18; and a first detection assembly 2, at least two of the first detection assemblies 2 being arranged opposite to each other, the bearing assembly 1 being located between the two oppositely arranged first detection assemblies 2, the first detection assembly 2 including a first detection member 26 and a movable first pusher member 25, the first pusher member 25 being movable toward the bearing space, the detection end of the first detection member 26 facing the bearing space.

[0020] In this embodiment, a hinge displacement detection device is used to detect the hinge. Taking a hinge that includes a rotatable first movable plate and a second movable plate as an example, the hinge in an open position is placed in the bearing space on the bearing seat 15. The first clamping member 13 moves towards the second clamping member 18 until the first clamping member 13 and the second clamping member 18 clamp the first movable plate. Then, the first pusher 25 in one of the first detection components 2 abuts against the second movable plate and applies pressure to the second movable plate. The first detection member 26 in the other first detection component 2 detects the displacement distance of the second movable plate. After the two first detection components 2 perform pusher and detection respectively, the displacement detection of the second movable plate in the hinge is completed. By setting the bearing component 1, the first clamping member 13 and the second clamping member 18 can automatically clamp the hinge, fixing one of the movable plates in the hinge. The two first detection components 2 apply pressure to one of the movable plates in the hinge and detect the displacement, so that the two first detection components 2 can cooperate with each other to complete the displacement detection of the movable plate in two axes, thereby realizing the automatic detection of the hinge by the first detection components 2 and improving the detection efficiency of the hinge.

[0021] Reference Figure 1 As shown, the hinge displacement detection device also includes a base plate 5, which supports the load-bearing component 1 and the first detection component 2.

[0022] Reference Figure 2As shown, the support assembly 1 includes a support base 15, a first clamping member 13 and a second clamping member 18. The second clamping member 18 is connected to the support base 15. The support base 15 is provided with a support space for accommodating the hinge. The first clamping member 13 can move toward the second clamping member 18. The support space is located between the first clamping member 13 and the second clamping member 18. When the hinge is placed in the support space, the first clamping member 13 and the second clamping member 18 can clamp the hinge by moving the first clamping member 13.

[0023] Specifically, the bearing assembly 1 further includes a first driving member 12, which is a clamping driving member, and the bearing seat 15 is connected to the first driving member 12. The bearing assembly 1 also includes a first support frame 11 and a support block 14. The first support frame 11 is connected to the base plate 5, and both the support block 14 and the first driving member 12 are connected to the top of the first support frame 11. The bearing seat 15 is also connected to the support block 14, thereby enabling the bearing seat 15 to remain stable. A pad 16 is provided on the bearing seat 15. The pad 16 corresponds to the clamping position between the first clamping member 13 and the second clamping member 18. The bearing space is located on the pad 16. The top side of the pad 16 is flat, so that the pad 16 can support the movable plate in the hinge and fit against the movable plate. The first clamping member 13 is connected to the output end of the first driving member 12. The first clamping member 13 and the second clamping member 18 are arranged opposite to each other, so that the first clamping member 13 and the second clamping member 18 can clamp the hinge.

[0024] The support assembly 1 also includes a stop 19. The support base 15 is further provided with an extension extending away from the pad 16, and the extension is located between the two first detection assemblies 2 arranged opposite to each other. A pad 17 is provided on the extension, and the plane on the support side of the pad 17 is coplanar with the plane on the support side of the pad 16. The pad 17 is used to support the movable plate in the hinge. The width of the extension and the pad 17 are both less than the maximum width of the support base 15, thereby avoiding interference between the extension and the pad 17 and the movement of the first pusher 25 in the first detection assembly 2. The stop 19 is connected to the support base 15 and is located on the opposite side of the extension. The stop 19, the first clamping member 13 and the second clamping member 18 can respectively abut against the three edges of the movable plate in the hinge, thereby positioning the movable plate and fixing its position.

[0025] Reference Figure 1 and Figure 3As shown, at least two first detection components 2 are arranged opposite to each other. In this embodiment, a total of two first detection components 2 are included, and the two first detection components 2 are arranged opposite to each other. The bearing component 1 is located between the two first detection components 2 arranged opposite to each other. The first detection component 2 includes a first detection element 26 and a movable first pusher element 25. The first pusher element 25 can move towards the bearing space so that the first pusher element 25 can abut against the movable plate in the hinge. The first detection element 26 can be regarded as a displacement measuring device connected to the controller. The detection end of the first detection element 26 faces the bearing space so that the first detection element 26 can detect the displacement of the movable plate.

[0026] The first detection component 2 further includes a second driving member 21 and a third driving member 22, both of which are linear driving members. The second driving member 21 is connected to the base plate 5. The third driving member 22 and the first detection member 26 are both connected to the output end of the second driving member 21. The driving path of the third driving member 22 is perpendicular to the driving path of the second driving member 21, and the driving path of the second driving member 21 is perpendicular to the rotation axis of the hinge, while the driving path of the third driving member 22 is parallel to the rotation axis of the hinge. The third driving member 22 can drive the first pusher 25 to move, thereby enabling the first pusher 25 to apply pressure to the movable plate in the hinge along the rotation axis of the hinge.

[0027] The first detection assembly 2 further includes a first movable seat 23 and a first sensor 24. The first sensor 24 is a pressure sensor and is connected to the controller, while the first movable seat 23 is connected to the output end of the third drive member 22. The first movable seat 23 and the first pusher 25 are connected to opposite sides of the first sensor 24, so that when the first pusher 25 abuts against the movable plate in the hinge, the first sensor 24 can detect the pressure applied by the first pusher 25, thereby maintaining the stability of the pressure applied by the first pusher 25 each time it is detected, and improving the accuracy of displacement detection. When the first pusher 25 in one of the first detection assemblies 2 abuts against the hinge and applies pressure to the second movable plate, the first detection member 26 in the other first detection assembly 2 detects the displacement distance of the movable plate in the hinge, so that the two first detection assemblies 2 can detect the displacement of the movable plate in two directions along the hinge rotation axis.

[0028] Reference Figures 4 to 6As shown, the hinge displacement detection device also includes a second detection component 3, which includes a fourth drive member 31, a fifth drive member 33, a second pusher member 36, a second sensor 35, and a second detection member 37. Both the fourth drive member 31 and the fifth drive member 33 are linear drive members, and the fourth drive member 31 is connected to the base plate 5. The output end of the fourth drive member 31 is connected to a second movable seat 32. The drive path of the fourth drive member 31 is perpendicular to the hinge's rotation axis, and the fourth drive member 31 can drive the second movable seat 32 to move closer to or further away from the bearing component 1. The fifth drive member 33 is connected to the second movable seat 32. The second sensor 35 is a pressure sensor connected to the controller. The output end of the fifth drive member 33 and the second pusher member 36 are connected to the opposite side of the second sensor 35, and the fifth drive member 33 can drive the second pusher member 36 and the second sensor 35 to rise and fall. The second detection element 37 is connected to the base plate 5 via the second support frame 34. The detection end of the second detection element 37 faces the bearing space. The second detection element 37 can be regarded as a displacement measuring device connected to the controller. The second detection element 37 is used to detect the displacement. When the second pusher 36 abuts against the movable plate of the hinge and applies pressure to the movable plate, the second detection element 37 can detect the displacement of the movable plate.

[0029] The second detection component 3 also includes a clamping mechanism 4, which includes a sixth driving member 42, a mounting plate 41, and third clamping members 44. The mounting plate 41 is connected to the bottom of the second movable seat 32 near the end of the bearing component 1. The sixth driving member 42 is a clamping driving member and is connected to the mounting plate 41. The two third clamping members 44 are connected to the output end of the sixth driving member 42. The clamping end of the third clamping member 44 is provided with a protrusion 45. The third clamping member 44 is driven to move by the sixth driving member 42, so that the third clamping member 44 can clamp the movable plate of the hinge. The protrusion 45 abuts against the edge of the movable plate.

[0030] The clamping mechanism 4 also includes a third sensor 43. The mounting plate 41 and the second movable seat 32 are slidably connected via a slide rail. The mounting plate 41 can move closer to or further away from the support assembly 1. The sixth drive member 42 and the second movable seat 32 are respectively connected to opposite sides of the third sensor 43. The third sensor 43 is a tension sensor connected to the controller, so that when the third clamping member 44 clamps the movable plate and the fourth drive member 31 drives the second movable seat 32 to move away from the support assembly 1, the third sensor 43 can detect the tension applied by the third clamping member 44 driving the movable plate.

[0031] The clamping mechanism 4 also includes two connecting blocks 46 arranged opposite to each other. The connecting blocks 46 are connected to the mounting plate 41. The sixth driving member 42 is located between the two connecting blocks 46. The sixth driving member 42 is slidably connected to the mounting plate 41 through a slide rail. The moving path of the sixth driving member 42 is perpendicular to the moving path of the second mounting plate 41. An elastic member 47 is provided between the sixth driving member 42 and the connecting blocks 46. The elastic member 47 can be regarded as a spring. In this way, when the third clamping member 44 clamps the movable plate in the hinge, it avoids the misalignment between the third clamping member 44 and the movable plate due to different hinge assembly, placement, size, etc., and thus avoids the third clamping member 44 being unable to clamp the movable plate. When there is a small misalignment between the third clamping member 44 and the movable plate, it can be adaptively adjusted by the movement of the sixth driving member 42.

[0032] The connecting block 46 is also connected to a limiting member 48. The limiting member 48 can be regarded as a screw and is threadedly connected to the connecting block 46. When the third clamping member 44 clamps the movable plate and the third clamping member 44 is misaligned with the movable plate, the end of the limiting member 48 can abut against the sixth driving member 42, thereby limiting the extreme movement position of the sixth driving member 42.

[0033] Preferably, the first support frame 11 is detachably connected to the base plate 5 by screws. When it is necessary to test the hinge in a closed position, the first support frame 11 is removed from the base plate 5 and rotated 180° in the horizontal direction. At this time, the bearing assembly 1 rotates 180°. Then, the first support frame 11 is reconnected to the base plate 5. Then, the obstructing parts on the detection path are removed, and the hinge in a closed position is placed in the bearing space. At this time, the top of the first clamping member 13 and the second clamping member 18 is lower than the height of the top side of the bottom movable plate of the hinge. The displacement of the movable plate located at the top can be detected by the first detection assembly 2 and the second detection assembly 3.

[0034] In use, taking a hinge including a first movable plate and a second movable plate that can rotate as an example, the hinge in an open position is placed in the bearing space on the bearing seat 15. The first clamping member 13 moves closer to the second clamping member 18 until the first clamping member 13 and the second clamping member 18 clamp the first movable plate. At this time, the second movable plate extends away from the pad 16 and abuts against the pad block 17. Then, the first pusher 25 in one of the first detection components 2 abuts against the second movable plate and applies pressure to the second movable plate. The first detection member 26 in the other first detection component 2 detects the displacement distance of the second movable plate. The two first detection components 2 perform pushing and detection respectively. Then, the second pusher 36 abuts against the second movable plate and applies pressure to the second movable plate. The second detection member 37 detects the displacement of the second movable plate. Finally, the third clamping member 44 clamps the second movable plate and applies tension to the second movable plate. The second detection member 37 detects the displacement of the second movable plate again. Finally, the displacement detection of the second movable plate in the hinge is completed. When it is necessary to detect the displacement of the hinge in the closed position, the first support frame 11 is disassembled from the base plate 5 and rotated 180° in the horizontal direction. Then the first support frame 11 is connected to the base plate 5, and the hinge in the closed position is placed in the bearing space. At this time, the second movable plate is located above the first movable plate. The first clamping member 13 and the second clamping member 18 clamp the first movable plate. The displacement of the movable plate located at the top is detected by the first detection component 2 and the second detection component 3.

[0035] This invention discloses a hinge displacement detection device. Through the arrangement of a support component 1, a first clamping member 13 and a second clamping member 18 can automatically clamp the hinge, fixing a movable plate within the hinge. Two first detection components 2 apply pressure to the movable plate and detect the displacement, enabling the two first detection components 2 to cooperate in detecting the displacement of the movable plate along two axes. This achieves automatic hinge detection by the first detection components 2, improving the detection efficiency. A second detection component 3 can detect the displacement of the movable plate under radial tension and pressure, thereby improving the comprehensiveness and accuracy of displacement detection. Furthermore, the second detection component 3 can automatically detect the hinge, further enhancing detection efficiency.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
