The height adjustment component 6 can detect the height between the pressure detection component 8 and the handle 3 in real time. When it is detected that the height difference between the pressure detection component 8 and the handle 3 is not at a preset value, the control component controls the rotating component to work, and the rotating component drives the handwheel 61 to rotate, so that the rotation drive component 5 moves up and down, driving the pressure detection component 8 to move up and down, until the height difference between the pressure detection component 8 and the handle 3 is at a preset value, further improving the degree of automation of the handle operation torque detection device.

[0052] In the embodiment of the present application, the rotating member is, for example, a rotatable motor or a cylinder. However, it should be understood that the rotating member may also be other suitable components with a rotating function.

[0054] In the embodiment of the present application, the support driving member is, for example, a cylinder, but it should be understood that the support driving member may also be any other suitable component that can drive the support plate to move up and down.

[0055] In one embodiment of the present application, Figure 1 As shown, the moving assembly 7 includes a guide rail 71 and a moving plate 72. The guide rail 71 is installed on the device body 1. The moving plate 72 is connected to the guide rail 71 through a slider. The mounting seat 4 is fixedly mounted on the moving plate 72. When in use, by applying an external force to the mounting seat 4, the mounting seat 4 can be moved along the slide rail.

When in use, the distance sensor can detect the distance between the mounting seat 4 and the handle 3 in real time, and transmit the detection data to the control member, thereby knowing the distance between the pressure detection assembly 8 and the handle 3. When the distance between the pressure detection assembly 8 and the handle 3 is not at a preset value, the control member sends a corresponding control signal to the driving member, so that the driving member drives the mounting seat 4 to move closer to or away from the handle 3 until the distance between the pressure detection assembly 8 and the handle 3 is at a preset value, thereby realizing the automatic adjustment of the distance between the pressure detection assembly 8 and the handle 3, and improving the automation of the handle operation torque detection device.

[0058] In the embodiment of the present application, the driving member is, for example, a motor or a cylinder, but it should be understood that the driving member may also be any other suitable component.

[0059] In one embodiment of the present application, Figure 1 As shown, the pressure detection assembly 8 includes a pressure sensor 81, a connecting shaft 82 and a roller 83. One end of the pressure sensor 81 is connected to the rotation drive assembly 5, and the connecting shaft 82 connects the other end of the pressure sensor 81 and the roller 83. When in use, the height and horizontal position of the rotation drive assembly 5 are adjusted by the height adjustment assembly 6 and the moving assembly 7. The height and horizontal position of the pressure detection assembly 8 are changed so that the roller 83 is located 2 mm above the detection point of the handle 3, or the roller 83 is in contact with the detection point of the handle 3. When the rotation drive assembly 5 drives the pressure sensor 81 to rotate, the connecting shaft 82 and the roller 83 rotate accordingly. When the roller 83 rotates, it drives the handle 3 to rotate coaxially together. The force at the handle 3 is transmitted to the pressure sensor 81 through the roller 83 and the connecting shaft 82, so that the pressure sensor 81 can detect the magnitude of the force applied to the handle 3 in real time. By abutting the roller 83 against the handle 3, the area of ​​the contact point between the pressure detection component 8 and the handle 3 can be effectively reduced. Compared with contacting the handle 3 through a needle-like structure, the roller 83 is not easily damaged or inserted into the handle 3, thereby ensuring smooth detection.

When in use, the infrared emission component 9 emits light to the detection point of the handle 3, so that the light spot of the infrared emission component 9 falls on the detection point of the handle 3. When the pressure detection component 8 is in point contact with the handle 3, the vertical distance from the first connection point to the axis of the handle 3 is the same as the vertical distance from the infrared light spot to the axis of the handle 3. By measuring the vertical distance from the infrared light spot to the axis of the handle 3, the length of the lever arm can be known. When the pressure detection component 8 is in surface contact with the handle 3, the vertical distance from the second connection point to the axis of the handle 3 is the same as the vertical distance from the infrared light spot to the axis of the handle 3. By measuring the vertical distance from the infrared light spot to the axis of the handle 3, the length of the lever arm can be known. Furthermore, by providing the infrared emitting component 9 , the length of the lever arm can be measured more conveniently, thereby facilitating the calculation of the torque of the handle 3 .

[0063] In the embodiments of the present application, Figure 1 As shown, the infrared emitting assembly 9 includes a mounting plate 91 and an infrared emitter, wherein the mounting plate 91 is fixedly mounted on the rotating drive assembly 5, and the infrared emitter is fixedly mounted on the mounting plate 91. When in use, the infrared emitter rotates with the rotation of the rotating drive assembly 5, so that the infrared light spot emitted by the infrared emitter is always at the detection point of the handle 3.
