The analog signal value range is small, the signal accuracy is poor, and the vehicle's water driving speed cannot be accurately controlled; and the coupling and the potentiometer shaft and the joystick connecting shaft are tightened and fixed by setscrews. Frequent operation will cause subtle failure forms such as loosening of the setscrews and rotation of the coupling, resulting in the inability to obtain analog signals or sensor damage, which cannot meet the needs of conventional simulation training.

[0027] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] like Figure 1 , 2 As shown in FIG. 4 , the water driving joystick simulation device for armored vehicle simulation training in this embodiment includes a joystick assembly 1, a joystick fixing frame 2 and a bolt 3, and the joystick assembly 1 is fixed to the joystick fixing frame 2 by the bolt 3. There are two joystick assembly 1, which are arranged at intervals up and down (i.e., divided into an upper handle and a lower handle), and the structures of the two are exactly the same. The joystick assembly 1 includes an operating rod weldment 4, a shield 5, a handle 6, a pin 7, a base 8, a damping rod 9, a large set screw 10, a limit screw 11, a bearing 12, a retaining ring 13, a bearing seat 14, a potentiometer mounting plate 15, a screw 16, a driven gear 17, an angle sensor 18, a potentiometer fixing frame 19, a coupling 20 and a small set screw 21.

[0029] like Figures 3 to 4 As shown, the operating rod weldment 4 includes an operating rod 22 and a driving gear 23, and the operating rod 22 and the driving gear 23 are connected by welding. The upper end of the operating rod weldment 4 is first inserted into the shield 5, and then connected to the handle 6 through a thread, and the other end is connected to the base 8 through a pin 7.

[0030] The damping rod 9 is first inserted into the screw hole on the base 8, and then the damping is fixed and adjusted by the large set screw 10. The operating rod weldment 4 passes through the damping rod 9, and the damping rod 9 corresponds to the middle part of the operating rod weldment 4. In this embodiment, compared with the prior art joystick operation, which only relies on the friction between the handle and the base to simulate damping, the use of the damping rod 9 ensures the operator's real operating force and feel. At the same time, the size of the damping rod 9 can be adjusted in real time as needed during use.

[0031] Limit screws 11 are installed in two symmetrical screw holes of the base 8 to control the angle of rotation of the operating rod weldment 4 to the left and right.

[0032] The bearing 12 is installed in the bearing seat 14 through the retaining ring 13 , and the bearing seat 14 is connected to the potentiometer mounting plate 15 through screws 16 .

[0033] The shaft end of the driven gear 17 is installed in the bearing 12 and then connected and fixed to one end of the coupling 20 by a small set screw 21.

[0034] The angle sensor 18 is fixed to the potentiometer fixing bracket 19 through the limiting hole and the nut of the angle sensor 18, and the shaft head of the angle sensor 18 is inserted into the other end of the coupling 20 and fixed by a small set screw 21. In this embodiment, the angle sensor 18 adopts an aluminum alloy elastic coupling to ensure the stability and accuracy of the transmission.

[0035] The potentiometer fixing frame 19 is connected to the potentiometer mounting plate 15 by screws 16; after the driven gear 17 is engaged with the driving gear 23 of the operating rod weldment 4, the potentiometer mounting plate 15 is connected to the base 8 by screws 16; the wide end of the shield 5 is inserted into the base 8 and fixed to the base by screws 16.

[0036] Finally, the assembled operating device handle assembly 1 is connected to the operating device fixing frame 2 via bolts 3 .

[0037] In this embodiment, the control device handle assembly 1 can be rotated to the left or right, and its rotation angle is controlled by the limit screw 11. In this embodiment, the middle position of the control device handle assembly 1 is neutral, and it can be rotated 22.5 degrees to the left and right, which is basically consistent with the rotation angle of the actual vehicle joystick. By operating the two control device handle assemblies 1, the vehicle can realize operations such as driving on water, changing speed, reversing and turning.

[0038] In this embodiment, the upper handle controls the water propulsion device on the right side of the vehicle, and the lower handle controls the water propulsion device on the left side of the vehicle; the upper and lower handles are pushed forward at the same time, the vehicle moves forward, and the upper and lower handles are pulled backward at the same time, the vehicle moves backward; when the upper handle is pushed forward to the maximum angle and the lower handle is pulled backward to the maximum angle, the vehicle turns left on the spot, and when the lower handle is pushed forward to the maximum angle and the upper handle is pulled backward to the maximum angle, the vehicle turns right on the spot; when the upper handle is pushed forward to the maximum angle and the lower handle is moved to the middle neutral position, the vehicle turns left, and when the lower handle is pushed forward to the maximum angle and the upper handle is moved to the middle neutral position, the vehicle turns right.

[0039] When the handle 1 of the operating device rotates, the active gear 23 on the operating rod weldment 4 drives the driven gear 17 and the high-precision angle sensor 18 to rotate synchronously, providing the angle sensor 18 with an interval analog quantity with a better acquisition effect, thereby realizing accurate acquisition and conversion of analog quantity signals.

[0040] A damping rod 9 is mounted on the base 8, and the damping size is adjusted by a large set screw 10 to simulate the operating force of a joystick for driving on water in a real vehicle and improve the degree of simulation.

[0041] In the above description, many specific details are elaborated to facilitate a full understanding of the present invention. However, the above examples are merely preferred implementation methods of the present invention and cannot be used to limit the scope of rights of the present invention. Simple modifications and equivalent changes made to the above examples based on the essence of the present invention still fall within the scope of the present invention.
