Description

Technical Field

[0001] The utility model relates to a reciprocating target swing device, in particular to a reciprocating target swing device for a target drone, and belongs to the field of military training equipment. Background Art

[0002] The target lifting and lowering machine is a common shooting training device, which is widely used in various military training and exercises. In order to make shooting training or exercises closer to actual combat, the target machine is usually required to have a lifting and lowering function to simulate the enemy's random hiding and other actions in actual combat, so as to improve the soldiers' shooting level and reaction speed. Most of the existing target lifting and lowering machines adopt a structure in which the target arm is directly connected to the motor spindle, and the motor spindle is used to directly drive the target arm to rotate, so that the target body is lifted or lowered to achieve hiding and visibility. However, in actual use, the existing target lifting and lowering machine is limited by the motor torque to complete the lifting and lowering load of a large target surface. Although the area of ​​the target lifting and lowering can be increased to a certain extent by increasing the specifications of the motor, it is limited by factors such as the outdoor field working environment or the mobility of the troops, and it cannot fundamentally solve the above problems. In addition, if the motor is fully loaded or overloaded for a long time, its service life will also be reduced, thereby affecting the overall life of the target machine. Summary of the invention

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a reciprocating target swing device which can increase the lifting and falling moment of the target surface and thus increase the load of the target drone.

[0004] In order to solve the above technical problems, the utility model provides a reciprocating target swing device, including a frame, a target arm shaft, and a driving mechanism. The target arm shaft is mounted on the frame and can rotate relative to the frame. A transmission mechanism is connected between the driving mechanism and the target arm shaft.

[0005] The driving mechanism controls the target arm shaft to reciprocate through the transmission mechanism.

[0006] In the utility model, the transmission mechanism includes a crank, a swing arm and a bearing;

[0007] The crank is provided with a strip groove / hole, and one end of the crank is fixedly connected to the target arm rotating shaft;

[0008] One end of the swing arm is connected to the driving mechanism, and the other end is connected to the bearing;

[0009] The bearing is embedded in the strip groove / hole and can roll back and forth along the strip groove / hole.

[0010] In the utility model, a pair of travel switches are arranged between the driving mechanism and the transmission mechanism, and the transmission mechanism is provided with a trigger mechanism matched with the travel switches.

[0011] In the utility model, the driving mechanism is a reduction motor.

[0012] The beneficial effects of the present invention are as follows: (1) the driving mechanism controls the target arm shaft to rotate back and forth quickly and stably through the transmission mechanism. The cooperation among the crank, the swing arm and the bearing to achieve force transmission can greatly increase the lifting and tilting torque of the target surface and increase the lifting and tilting load of the entire target machine to meet the requirements of the visibility and hiding of target surfaces of different areas; (2) the bearing is embedded in the strip groove / hole and can roll back and forth along the strip groove / hole. While increasing the lifting and tilting load of the entire target machine, it can also reduce the friction between the two, thereby improving the stability and reliability of the entire target machine to meet the needs of high-intensity, long-term continuous work; (3) the target machine can be fully protected by the travel switch to ensure the safety of various electrical components and mechanical parts; (4) the present invention has a simple structure, few transmission parts, reliable connection, small mechanical clearance, and is easy to process and install.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] 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.

[0023] like Figure 1 As shown, the reciprocating target swing device of this embodiment is now described in detail by taking the target drone used for shooting at armored vehicles as an example. The reciprocating target swing device of the utility model comprises a frame 1, a reduction motor 2, a crank 3, a swing arm 4, a bearing 5, a target arm rotating shaft 6 and a travel switch 7.

[0024] The reduction motor 2 and the target arm shaft 6 are respectively mounted on the frame 1 . The reduction motor 2 is located below the target arm shaft 6 . The target arm shaft 6 can rotate relative to the frame 1 .

[0025] One end of the crank 3 is fixedly connected to the output shaft of the reduction motor 2 through a flat key, and the other end of the crank 3 is sleeved with a bearing 5.

[0026] One end of the swing arm 4 is welded to the target arm shaft 6, and a strip hole 4-1 is provided along the length direction of the swing arm 4, and the bearing 5 is embedded in the strip hole 4-1 of the swing arm 4. When the reduction motor 2 rotates, the crank 3 causes the bearing 5 to move up and down in the strip long hole of the swing arm 4, converting the rotation of the reduction motor 2 into the swinging motion of the swing arm 4, thereby driving the swinging of the target arm shaft 6, and realizing the lifting and falling function of the target drone.

[0027] In this embodiment, the length of the strip hole 4 - 1 is greater than the stroke of the bearing 5 .

[0028] Those skilled in the art should know that the strip-shaped hole 4 - 1 may also be replaced by a strip-shaped groove to implement the technical solution of the present utility model.

[0029] The reduction motor 2 realizes the reciprocating rotation of the target arm shaft 6 by rotating forward and reversely.

[0030] In this embodiment, there are two travel switches 7, which are fixed on the outer side of the output shaft of the reduction motor 2, respectively in the target start state position and the target inverted state position. The crank 3 is provided with a magnet (not shown in the figure) that matches the travel switch 7, and the magnet is used to trigger the travel switch 7.

[0031] The target surface clamping mechanism 8 is fixedly mounted on both ends of the target arm rotating shaft 6. Figure 1 The target surface is in the up-target state, and the travel switch 7 on the left is in effect. At this time, if the target surface is to be turned down, the reduction motor is controlled to rotate counterclockwise, driving the crank 3 to rotate counterclockwise, and the bearing 5 moves from top to bottom in the long slot of the swing arm 4, driving the swing arm 4 and the target arm rotating shaft 6 to rotate counterclockwise. When the magnet on the crank 3 approaches the travel switch 7 on the right, the reduction motor 2 stops rotating, the bearing 5 moves to the lower end of the long slot of the swing arm 4, and the swing arm 4 and the target arm rotating shaft 6 stop rotating. At this time, the target surface is in the inverted target state. The reduction motor 2 moves in the opposite direction to make the target surface stand up, thereby realizing the hidden and visible function of the target machine.

[0032] The travel switch 7 in the utility model has a runaway protection function. If one or both of the travel switches 7 are damaged during operation, when the reduction motor 2 rotates a full circle, the swing arm 4 will not rotate a full circle, but can only swing left and right, that is, the target surface is continuously raised and lowered back and forth, which will not cause any mechanical damage to any electrical components and parts.

[0033] In actual use, the frame 1 can be quickly connected and matched with other external components. It has a simple structure, few transmission parts, reliable connection, and is easy to process and install.

[0034] 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.
