DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0031] See also Figure 1-Figure 4 、 Figure 7As shown, in an embodiment of the present utility model, a handlebar sensitivity detection mechanism is proposed, including a support plate 1 and a fixed end face locking block 2 installed at one end of the support plate 1, a screw mechanism 3 is provided on the support plate 1, and the screw mechanism 3 includes a screw nut 31 and a movable end face locking block 4 installed on the screw nut 31. The movable end face locking block 4 is moved by adjusting the screw mechanism 3 so that the distance between the movable end face locking block 4 and the fixed end face locking block 2 meets the requirements for positioning the support plate 1 on the cockpit, thereby positioning the entire detection mechanism.
[0032] A first sliding module 5 and a second sliding module 6 slidably mounted on the pallet 1 are slidably mounted, the sliding directions of the first sliding module 5 and the second sliding module 6 being arranged perpendicularly, a first servo motor 7 for driving the first sliding module 5 to slide is mounted on the pallet 1, a second servo motor 8 for driving the second sliding module 6 to slide is mounted on the first sliding module 5, the first servo motor 7 drives the first sliding module 5 to move on the pallet 1, and moves synchronously with the second sliding module 6, while the second servo motor 8 drives the second sliding module 6 to slide relative to the first sliding module 5, the first sliding module 5 slides along the X direction, and the second sliding module 6 slides along the Y direction, maintaining a vertical manner.
[0033] A displacement sensor 9 is mounted on the second sliding module 6 , thereby enabling the displacement sensor 9 to translate in the XY plane.
[0034] Specifically, a clamp 10 is connected to the displacement sensor 9. The clamp 10 is used to clamp the handle 100. The displacement sensor 9 drives the handle 100 to move within the XY plane, thereby simulating the operation of the handle 100. At the same time, the support plate 1 is also provided with a first pressure sensor 11 for detecting the pressure of the second sliding module 6 in a first direction, and a second pressure sensor 12 for detecting the pressure of the second sliding module 6 in a second direction. The first direction is perpendicular to the second direction. The first pressure sensor 11 and the second pressure sensor 12 detect the first pressure value of the second sliding module 6 in the X direction and the second pressure value in the Y direction, thereby determining the relationship between the first pressure value and the displacement in the X direction, and the relationship between the second pressure value and the displacement in the Y direction.
[0035] Specifically, the acquired parameters can be used to form a curve graph with the horizontal axis being the displacement coordinate and the vertical axis being the first pressure value and the second pressure value. The curve graph can be compared with the curve graph of the initial state to acquire the relevant parameters that need to be calibrated, and it can be determined whether sensitivity correction is needed.
[0036] Thus, the sensitivity detection of the handle 100 can be achieved when the handle 100 is installed on the cockpit, thereby improving the convenience of sensitivity detection.
[0037] Specifically, in order to allow the first sliding module 5 and the second sliding module 6 to slide stably, a first guide rail 13 for guiding the first sliding module 5 and a second guide rail 14 for guiding the sliding of the second sliding module 6 are provided on the support plate 1. The first guide rail 13 and the second guide rail 14 both adopt a box structure, and guide rods can be used inside to achieve sliding guidance.
[0038] Specifically, a first screw mechanism is installed in the first guide rail 13, and the first screw mechanism is connected to the first servo motor 7. The first servo motor 7 and the first screw mechanism realize the reciprocating sliding of the first sliding module 5. Similarly, a second screw mechanism is installed in the second guide rail 14, and the second screw mechanism is connected to the second servo motor 8. The second servo motor 8 and the second screw mechanism realize the reciprocating sliding of the second sliding module 6.
[0039] Specifically, the screw mechanism 3 is used to drive the screw nut 31 to translate, so as to realize the movement of the movable end face locking block 4 and realize the positioning and installation of the support plate 1. The screw mechanism 3 includes a rotating screw rod 32 rotatably mounted on the support plate 1, and the screw nut 31 is threadedly connected to the rotating screw rod 32. The support plate 1 is provided with a sliding groove 33 for limiting the sliding of the screw nut 31. The sliding groove 33 limits the sliding of the screw nut 31, and the rotating screw rod 32 is threadedly matched with the screw nut 31. When the rotating screw rod 32 is driven to rotate, the screw nut 31 can move back and forth in the sliding groove 33. Specifically, a hand wheel 34 is connected to the end of the rotating screw rod 32 extending out of the support plate 1, and the rotating screw rod 32 is driven to rotate by the hand wheel 34.
[0040] In order to lock the state of the rotating screw 32 after rotation and prevent the rotating screw 32 from self-rotating, a locker 35 for limiting the rotation of the rotating screw 32 is installed on the support plate 1. The locker 35 can adopt a screw structure to press against the rotating screw 32 after rotation to achieve limitation, thereby preventing the rotating screw 32 from rotating and preventing it from loosening during the detection process to affect the accuracy of the detection results.
[0041] At the same time, in order to facilitate the movement of the entire detection mechanism, handles 15 are installed at intervals on the support plate 1.
[0042] When the handle 100 is moved, the handle 100 is clamped by the clamp 10. Figure 5 、 Figure 6As shown, the clamp 10 includes a first clamping buckle 101 and a second clamping buckle 102 rotatably mounted on the first clamping buckle 101. A locking structure is provided between the first clamping buckle 101 and the second clamping buckle 102. The handle 100 is clamped in the circumferential direction by the first clamping buckle 101 and the second clamping buckle 102. At the same time, a third clamping buckle 103 is rotatably provided on the first clamping buckle 101. The rotation direction of the third clamping buckle 103 is perpendicular to the rotation direction of the second clamping buckle 102. The third clamping buckle 103 is used to further position the handle 100, so that the clamp 10 and the handle 100 can keep moving synchronously. A detection ball head 104 is fixed on the third clamping buckle 103. The detection ball head 104 is used to be inserted into the displacement sensor 9. The detection ball head 104 is connected to the displacement sensor 9. Since the clamp 10 and the handle 100 move synchronously, the displacement sensor 9 can exert a balanced force on the detection ball head 104 to ensure the accuracy of displacement coordinate detection. The displacement parameters of the handle 100 can be obtained by detecting the displacement of the clamp 10.
[0043] At the same time, a lining 105 is provided on the inner wall of the first clamping buckle 101 and the second clamping buckle 102. The lining 105 protects the handle 100 when clamping and prevents slipping in the clamping state.
[0044] Specifically, the locking structure includes a locking pin 106 rotatably installed on the second clamping buckle 102, and the first clamping buckle 101 is provided with a limiting notch 107 for cooperating with the locking pin 106. When the first clamping buckle 101 and the second clamping buckle 102 are fastened, the locking pin 106 is rotated to engage in the limiting notch 107 to lock the first clamping buckle 101 and the second clamping buckle 102.
