[0045] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0046] Figure 1 It is a schematic diagram of the three-dimensional structure of the joystick testing device shown in an embodiment of the present application.

[0047] See also Figure 1 The present application provides a joystick testing device for an aircraft, comprising at least one actuator 111, a pointer assembly 130, and a dial assembly; the actuator 111 can move in a predetermined direction, the pointer assembly 130 is fixed relative to the joystick 300, the actuator 111 is used to drive the pointer assembly 130 so that the joystick 300 moves along a predetermined trajectory with the pointer assembly 130, the pointer assembly 130 includes at least one pointer, and the dial assembly includes at least one dial, which is arranged at the motion trajectory of the joystick 300, and when the pointer assembly 130 moves, it is used to drive the pointer to point to different scales of the dial to measure the movement data of the joystick 300.

[0048] The joystick testing device provided in the present application can drive the pointer assembly 130 to move along a predetermined trajectory when the actuator 111 moves in a predetermined direction. Since the pointer assembly 130 is fixed to the joystick 300, the movement data of the joystick 300 can be obtained through the cooperation of the pointer and the dial. The movement data can be the stroke displacement data of the joystick 300. Compared with the related art, the joystick 300 testing device of the present application has a simple structure and can realize the side-view operation of the joystick without the need for electrical or pneumatic assistance. Therefore, it has no restrictions on the use site, is easy to carry, and has strong flexibility.

[0049] In some embodiments, the device of the present application includes a first mounting base 100, with at least one actuator 111 mounted on the first mounting base 100. The first mounting base 100 is provided with a support portion, which is provided with a mounting portion for mounting the actuator 111. Specifically, the first mounting base 100 includes a base plate that can be fixed to the bottom of the joystick 300. The joystick 300 extends upward from the middle of the base plate. A support 110 protrudes upward from the edge of the base plate, and the support 110 serves as the support portion.

[0050] The mounting portion can be a mounting hole opened horizontally in the support portion, and the actuator 111 can be a push rod installed in the mounting hole. The push rod is threaded with the mounting hole. For example, the push rod can be inserted into the mounting hole, and the surface of the push rod is provided with an external thread, and the hole wall of the mounting hole is provided with an internal thread. When the push rod rotates, it can move in the mounting hole along the axial direction of the mounting hole.

[0051] In the present application, the axial ends of the push rod are respectively an operating end 1111 and a driving end 1112. The operating end 1111 is the end away from the pointer assembly 130 and is located on the lateral outer side of the base plate, while the driving end 1112 is the end close to the pointer assembly 130 and is located on the lateral inner side of the base plate. The operating end 1111 is provided with a handle, which can be used to rotate the push rod to move the driving end 1112 away from or close to the pointer assembly 130. When the driving end 1112 contacts the pointer assembly 130 and the push rod continues to be rotated, the pointer assembly 130 can move under the push of the push rod. Since the pointer assembly 130 and the joystick 300 are fixed, the travel distance of the pointer assembly 130 is the same as the travel distance of the joystick 300, and the angle data of the pointer on the dial is read.

[0052] In the present application, because the push rod is threadedly engaged with the mounting hole, the push rod can be positioned axially when it is moved to any position, thereby allowing the pointer assembly 130 to be positioned at any scale on the dial, making it easier for the user to read test data. In some embodiments, the push rod is also provided with a displacement scale for displaying the distance the push rod has moved axially. The travel displacement of the joystick 300 can be calculated based on the axial travel distance of the push rod and the angle data of the joystick 300.

[0053] It can be understood that the positioning method of the push rod in the present application may not be limited to the threaded matching structure between the push rod and the mounting hole. In other embodiments, there may be no threaded structure between the push rod and the mounting hole, and the push rod can move freely axially in the mounting hole. A locking mechanism is provided between the push rod and the support portion, and the locking mechanism is used to position the push rod at any position in its axial direction. Specifically, the locking structure may be a snap-on, lock, or other structure.

[0054] In some embodiments, the driving end 1112 of the push rod can be designed as a nut structure, and the push rod can be screwed in and out along its axial direction by an electric wrench. When the driving end 1112 pushes the pointer assembly to approach the test position, manual adjustment is used to accurately determine the test angle. In some embodiments, a force sensor and a displacement sensor are provided between the driving end and the pointer assembly. The force sensor is used to sense the pressure information of the driving end acting on the pointer assembly, and the displacement sensor is used to sense the distance information moved after the driving end abuts against the pointer assembly. The force sensor and the displacement sensor are electrically connected to the control system, and the control system can accurately output the stroke value of the joystick 300 and the force value corresponding to the operating position.

[0055] In some embodiments, an image acquisition device connected to the control system is further included, and the image acquisition device is used to obtain scale image information pointed to by the pointer on the dial. The control system calculates the stroke displacement data of the joystick and the information on the force required for operation based on the scale value pointed to by the pointer displayed in the scale image information, the stroke value of the joystick and the force value of the operating position.

[0056] See also Figure 3 and Figure 4 In some embodiments, a drive mating portion is provided at a position of the pointer assembly 130 opposite to the end of the push rod, and the drive end 1112 is used to abut against the drive mating portion, thereby driving the pointer assembly 130 to move via the drive mating portion. Specifically, the pointer assembly 130 includes a fixed block 1301, and the drive mating portion and the pointer are both provided on the fixed block 1301. The fixed block 1301 is fixed to the joystick 300, and the drive mating portion can be a groove, protrusion, or stopper provided on the fixed block 1301. The drive end 1112 of the push rod can abut against the groove, protrusion, or stopper, thereby pushing the fixed block 1301 to move or rotate, thereby causing the pointer to move or rotate accordingly.

[0057] In some embodiments, the guide member 120 includes a main body having a curved surface, which is located above the floor of the first mounting seat 100 and fixed to the bottom plate; the guide groove 121 is opened in the main body, and the curvature of the curved surface is the same as the curvature of the movement of the joystick 300; the pointer is located at a position of the fixed block 1301 close to the curved surface, the dial is located on the curved surface, and the pointer moves along the curved surface.

[0058] Furthermore, an accommodating portion is provided in the center of the guide member 120, which is used to accommodate the joystick 300 in the initial position. Guide grooves 121 connected to the accommodating portion are provided around the accommodating portion along the front, rear, left and right directions respectively. The joystick 300 can move from the accommodating portion to the guide grooves 121 in the front, rear, left and right directions along with the pointer assembly 130. In this way, the fixed block 1301 of the pointer assembly 130 moves on the correct track, that is, the swing or rotation angle of the joystick 300 during the operation process can be accurately obtained.

[0066] See also Figure 5In some embodiments, the device of the present application includes a second mounting base for assembling on the end of the joystick, and the second mounting base is provided with a mounting portion for mounting a third push rod 111c. The third push rod 111c is arranged in the vertical direction and is threadedly connected to the mounting portion.
