It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can also be made, which should be considered as the protection scope of the present application.

[0041] Reference Figures 1 to 3 The present application provides a sliding swing target machine, comprising a tilt setting slide rail 1, a sliding trolley 2, a swing rod 3 and a transmission connecting rod 4; the sliding trolley 2 comprises a base 21, a swing frame 22 and a rolling bearing 23, the base 21 is suitable for sliding installation on the slide rail 1, the swing frame 22 is arranged on the base 21, the swing frame 22 is provided with a first rotating shaft 221, and the rolling bearing 23 is suitable for abutting and rolling on the inner side wall of the slide rail 1; the swing rod 3 is rotationally connected with the swing frame 22 through the first rotating shaft 221, the swing rod 3 is fixed with a sliding frame 31 at the bottom, and the sliding frame 31 is provided with a sliding groove 311 at the bottom; the transmission connecting rod 4 is connected with the rolling bearing 23 and rotates circumferentially around the rolling bearing 23, and the top end of the transmission connecting rod 4 is slidingly arranged in the sliding groove 311 of the sliding frame 31; when the sliding trolley 2 moves along the slide rail 1, the rolling bearing 23 is driven to rotate by the inner side wall of the slide rail 1, thereby driving the transmission connecting rod 4 to move, the sliding of the end of the transmission connecting rod 4 in the sliding groove 311 drives the swing rod 3 to make reciprocating swing movement around the first rotating shaft 221 along the length direction of the slide rail 1.

[0042] In the embodiment, when the sliding trolley 2 moves along the slide rail 1, the rolling bearing 23 is driven to rotate by the inner side wall of the slide rail 1, thereby driving the transmission connecting rod 4 to move, the sliding of the end of the transmission connecting rod 4 in the sliding groove 311 drives the swing rod 3 to make reciprocating swing movement around the first rotating shaft 221 along the length direction of the slide rail 1, so that the target mark 6 on the swing rod 3 can reciprocate and swing, effectively improving the difficulty of training to meet the increasingly complex and variable training needs.

[0043] Specifically, the sliding trolley 2 is composed of a base 21, a swing frame 22, a rolling bearing 23 and a transmission connecting rod 4. The base 21 can precisely fit the slide rail 1 and realize the smooth sliding of the sliding trolley 2 on the pair of slide rails 1. The swing frame 22 is installed on the base 21 and is equipped with a first rotating shaft 221. The swing rod 3 is tightly connected with the swing frame 22 through the first rotating shaft 221. The first rotating shaft 221 ensures that the swing rod 3 can freely swing within a certain angle range. The bottom of the swing rod 3 is provided with a sliding frame 31. The bottom of the sliding frame 31 is provided with a sliding groove 311 for cooperating with the transmission connecting rod 4 to realize complex motion conversion. During the sliding process of the sliding trolley 2, the rolling bearing 23 is responsible for closely contacting and smoothly rolling with the inner side wall of the slide rail 1, which refers to the side wall of one end of the pair of slide rails 1. The transmission connecting rod 4 is an important component connecting the rolling bearing 23 and the swing rod 3. One end of the transmission connecting rod 4 is connected with the rolling bearing 23 and can rotate around the rolling bearing 23 in the circumferential direction following the rotation of the rolling bearing 23. The other end of the transmission connecting rod 4 can slide in the sliding groove 311 of the sliding frame 31. When the rolling bearing 23 rotates under the drive of the inner side wall of the slide rail 1, the transmission connecting rod 4 moves accordingly, and then drives the swing rod 3 to swing around the first rotating shaft 221 through the cooperation of the transmission connecting rod 4 and the sliding groove 311, and further converts the rotating force of the transmission connecting rod 4 into the left and right swinging force of the swing rod 3. The top of the swing rod 3 is also provided with a fixing port 32 for installing and fixing the target 6. The target 6 is inserted into the fixing port 32 at the bottom, and then fastened by a locking member to complete the installation and fixation of the target 6. The fixing port 32 ensures that the target 6 remains stable during the swinging process and does not loosen or deviate. The opening shape and size of the fixing port 32 are suitable for various types of targets 6, which facilitates quick replacement and installation and meets different training needs.

[0044] More specifically, when the sliding trolley 2 moves along the slide rail 1, the rolling bearing 23 contacts and rotates with the inner side wall of the slide rail 1. The rotation of the rolling bearing 23 drives the transmission connecting rod 4 to move. Since the top end of the transmission connecting rod 4 is slidingly arranged in the sliding groove 311 of the sliding frame 31, the movement of the transmission connecting rod 4 is converted into sliding in the sliding groove 311. This sliding further drives the sliding frame 31 to swing back and forth in the length direction of the slide rail 1, similar to the principle of a lever, and then drives the swing rod 3 to swing around the first rotating shaft 221, so that the target 6 installed at the top end of the swing rod 3 can perform reciprocating swinging motion in the length direction of the slide rail 1. The cooperation of the rolling bearing 23 and the transmission connecting rod 4 ensures the stable swinging of the swing rod 3, improves the stability and safety of the training. In addition, the target machine can simulate complex and variable target motion states, not only effectively improving the difficulty and challenge of the training, but also simulating the complex motion states of targets in various actual combat environments, providing highly realistic and diversified simulation scenes for military training, police tactical training and various shooting training, etc., thereby accurately meeting the increasingly complex and variable training needs and greatly improving the training effect and real combat adaptability.

[0045] Preferably, with reference to Figure 4 and Figure 5 , the rolling bearing 23 comprises an outer ring 231, an inner ring 232 and rolling bodies 233 arranged between the outer ring 231 and the inner ring 232, the outer side wall of the outer ring 231 is adapted to roll against the inner side wall of the slide rail 1, the sliding frame 31 is arranged along the width direction of the slide rail 1, and the transmission connecting rod 4 comprises a first transmission rod 41, the first transmission rod 41 comprises a rolling part 411 and a sliding part 412, the rolling part 411 is arranged between the outer ring 231 and the inner ring 232 and is driven to roll by the rolling bodies 233, and the sliding part 412 extends along the axial direction of the rolling bearing 23 and is inserted into the sliding groove 311 of the sliding frame 31.

[0046] In the embodiment, the rolling part 411 is located between the outer ring 231 and the inner ring 232 and is directly driven to rotate circumferentially by the rolling bodies 233, and the sliding part 412 extends along the axial direction of the rolling bearing 23 and is inserted into the sliding groove 311 of the sliding frame 31, which not only ensures the movement accuracy of the transmission connecting rod 4, but also improves the stability and reliability of the system.

[0047] Specifically, the rolling bearing 23 mainly comprises an outer ring 231, an inner ring 232 and rolling bodies 233 arranged between the outer ring 231 and the inner ring 232. The outer side wall of the outer ring 231 closely fits the inner side wall of the slide rail 1 and can smoothly roll along the inner side wall of the slide rail 1 under the action of external force. The inner ring 232 is connected with the base 21 of the sliding trolley 2 and remains relatively stable. The rolling bodies 233 efficiently roll between the inner ring 232 and the outer ring 231, thereby realizing the smooth circumferential rotation of the outer ring 231 relative to the inner ring 232. The transmission connecting rod 4 comprises a first transmission rod 41, which is arranged along the axial direction of the rolling bearing 23 and has a rolling part 411 and a sliding part 412 arranged at the two axial ends thereof. The rolling part 411 is arranged between the outer ring 231 and the inner ring 232 and is directly driven to rotate circumferentially by the rolling bodies 233. The sliding part 412 extends along the axial direction of the rolling bearing 23 and is inserted into the sliding groove 311 of the sliding frame 31.

[0048] Specifically, the circumferential rolling of the rolling bodies 233 inside the rolling bearing 23 is the key to driving the circumferential rotation of the first transmission rod 41. When the sliding trolley 2 moves along the slide rail 1, the circumferential rolling of the rolling bodies 233 inside the rolling bearing 23 drives the rolling part 411 of the first transmission rod 41 to rotate, i.e., the first transmission rod 41 rotates circumferentially around the rolling bearing 23, at which time the sliding part 412 of the first transmission rod 41 slides in the sliding groove 311 along the width direction of the slide rail 1, driving the sliding frame 31 to swing back and forth along the length direction of the slide rail 1, and further driving the swing rod 3 to swing back and forth around the first rotation shaft 221, thereby realizing the complex motion trajectory of the target 6.

[0049] It is worth noting that the rolling part 411 of the first transmission rod 41 of the present application is similar to the rolling body 233, which is arranged between the inner ring 232 and the outer ring 231, but the diameter of the rolling part 411 is smaller than that of the rolling body 233, that is, the rolling part 411 is not in direct contact with the inner ring 232 and the outer ring 231, and it can only be driven by the circumferential rotation of the rolling body 233. Of course, in the transformed embodiment, the first transmission rod 41 can also be directly fixedly connected to the outer ring 231, and the circumferential rotation of the first transmission rod 41 is realized by the rotation of the outer ring 231, that is, the first transmission rod 41 is caused to rotate following the rotation of the outer ring 231. The difference between the present embodiment and the above-mentioned embodiment lies in how to realize the circumferential rotation of the first transmission rod 41 around the rolling bearing 23, which is within the protection scope of the present application. Moreover, the rolling part 411 of the first transmission rod 41 is matched with the rolling body 233 in the present application, because the outer ring 231 is in rolling abutment with the inner side wall of the slide rail 1, so that the rotation speed of the outer ring 231 is too fast, and in turn the swinging speed of the swing rod 3 is too fast, while the rolling speed of the rolling body 233 is slower. Therefore, the rolling part 411 is arranged at the bottom end of the first transmission rod 41 in the present application, and the rotation of the rolling part 411 and the first transmission rod 41 is realized by the rotation of the rolling body 233. The movement characteristics of the rolling body 233 are ingeniously utilized, so that the rotation speed of the transmission connecting rod 4 and subsequent transmission components can be effectively controlled, avoiding problems such as unstable transmission or mechanical wear caused by too high rotation speed, ensuring the stability and reliability of the entire transmission connecting rod 4, and in turn improving the working performance and service life of the target machine. It is worth emphasizing that the rotation of the first transmission rod 41 is circumferential rotation around the rolling bearing 23, rather than the autorotation of the first transmission rod 41.

[0050] Further, the rolling bearing 23 further comprises a fixed seat 234, the inner ring 232 is fixedly sleeved on the fixed seat 234, the transmission connecting rod 4 further comprises a center shaft 42 and a second transmission rod 43, the center shaft 42 is coaxially fixedly arranged at the center of the fixed seat 234, and the second transmission rod 43 is pivotally connected to one end of the center shaft 42 and fixedly connected to the other end of the first transmission rod 41.

[0051] In the present embodiment, the rotation of the second transmission rod 43 around the center shaft 42 can ensure that the first transmission rod 41 always remains in the vertical direction, so that the movement of the first transmission rod 41 is more stable and accurate.

[0052] Specifically, the inner ring 232 is fixed by the fixed seat 234 to enhance the stability of the inner ring 232 and effectively reduce the shaking of the inner ring 232 during transmission, thereby improving the stability. The transmission connecting rod 4 includes a center shaft 42 and a second transmission rod 43. The center shaft 42 is coaxially fixed at the center position of the fixed seat 234, ensuring the coaxial rotation accuracy of the transmission connecting rod 4. One end of the second transmission rod 43 is connected to the center shaft 42 through a pivot, and the other end is fixedly connected to the first transmission rod 41, so that the second transmission rod 43 can rotate flexibly around the center shaft 42, thereby ensuring that the first transmission rod 41 always maintains a vertical direction and rotates circumferentially around the center shaft 42, which can avoid additional stress and wear caused by tilting or deviation, thereby improving the stability and accuracy of transmission.

[0053] Further, the eccentric mechanism 5 is also included, which includes an eccentric shaft 51 and a torsional spring 52. The eccentric shaft 51 is fixedly connected to the fixed seat 234 and the base 21, and the torsional spring 52 is sleeved on the eccentric shaft 51. The base 21 is also provided with an elastic column 211, and one end of the torsional spring 52 is connected to the fixed seat 234 and the other end is connected to the elastic column 211. The torsional spring 52 is in a pre-torsion state, and the torsional moment generated thereby drives the entire rolling bearing 23 to rotate and deviate to one side around the axis of the eccentric shaft 51, thereby forcing the outer ring 231 of the rolling bearing 23 to continuously abut against the inner side wall of the slide rail 1.

[0054] In this embodiment, the pre-tightening force of the torsional spring 52 drives the entire rolling bearing 23 to deviate to one side, ensuring that the outer ring 231 of the rolling bearing 23 continuously abuts against the inner side wall of the slide rail 1.

[0055] Specifically, the eccentric mechanism 5 is composed of an eccentric shaft 51 and a torsional spring 52. The eccentric shaft 51 is fixedly connected between the fixed seat 234 and the base 21 of the sliding trolley 2. The torsional spring 52 is sleeved on the eccentric shaft 51, one end of the torsional spring 52 is connected to the fixed seat 234, and the other end is connected to the elastic column 211 on the base 21. The torsional spring 52 is in a pre-torsion state and generates a continuous torsional moment, which drives the entire rolling bearing 23 to rotate and deviate to one side around the axis of the eccentric shaft 51, forcing the outer ring 231 of the rolling bearing 23 to always abut tightly against the inner side wall of the slide rail 1, ensuring stable contact between the rolling bearing 23 and the slide rail 1, thereby improving the smoothness and accuracy of the sliding trolley 2 when moving on the slide rail 1.

[0056] Preferably, the axis of the eccentric shaft 51 is parallel to the axis of the central shaft 42 and is arranged along the length direction of the slide rail 1, which ensures that the eccentric mechanism 5 can uniformly apply torque on the slide rail 1, so that the outer ring 231 of the rolling bearing 23 is always in close contact with the inner side wall of the slide rail 1. The top of the eccentric shaft 51 is also provided with a snap spring, which abuts against the top of the fixing seat 234 and is used for axially limiting the fixing seat 234. This not only enhances the stability of the fixing seat 234, but also ensures that the eccentric shaft 51 will not axially displace during the working process, thereby improving the reliability of the target machine.

[0057] It is worth noting that the eccentric mechanism 5 can effectively cope with the slight unevenness or installation error of the inner side wall of the slide rail 1, and ensure that the rolling bearing 23 is always in good contact with the slide rail 1, which not only prolongs the service life of the equipment, but also enhances the stability and safety of the training. In the transformed embodiment, the base 21 can also be provided with two elastic columns 211, which are respectively located on both sides of the eccentric shaft 51 and are symmetrically arranged along the length direction of the slide rail 1. The two ends of the torsion spring 52 are elastically connected to the two elastic columns 211, and the two elastic columns 211 provide two stable connection points for the torsion spring 52 to realize the pre-torsion of the torsion spring 52. This pre-torsion state makes the torsion spring 52 always generate a continuous torsion torque, which drives the rolling bearing 23 to rotate and offset to one side around the axis of the eccentric shaft 51. Whether one elastic column 211 or two elastic columns 211 is provided, as long as the pre-torsion of the torsion spring 52 can be realized, it is within the protection scope of the present application.

[0058] Further, the base 21 is also provided with a pair of pulley sets 24 on both sides in the width direction of the slide rail 1, which are rollably arranged in the guide groove of the slide rail 1 and are used for supporting the base 21 and guiding it to move along the slide rail 1; the swing frame 22 is arranged between the pair of pulley sets 24 in the width direction of the slide rail 1.

[0059] In the embodiment, the base 21 is provided with a pair of pulley sets 24 on both sides in the width direction of the slide rail 1, which are rollably arranged in the guide groove of the slide rail 1 and are used for supporting the base 21 and guiding it to move along the slide rail 1.

[0060] Specifically, a pair of slide rails 1 are arranged at intervals along the width direction thereof, each slide rail 1 is provided with a sliding groove 311, and a pair of pulley sets 24 are arranged on both sides of the slide rail 1 in the width direction of the base 21. The pulley set 24 is rollably arranged in the guide groove of the slide rail 1, plays a role of supporting the base 21 and guiding the movement of the base 21 along the slide rail 1, and can effectively reduce the friction between the base 21 and the slide rail 1, ensure the smooth sliding of the sliding trolley 2 on the slide rail 1, and improve the positioning accuracy of the sliding trolley 2. The outer edge of the pulley is closely attached to the guide groove of the slide rail 1, reducing shaking and further improving the stability of sliding. The swing frame 22 is arranged between the pair of pulley sets 24 along the width direction of the slide rail 1, so that the swing frame 22 can remain stable during the movement of the sliding trolley 2, and provides a solid foundation for the installation and swinging of the swing rod 3. The swing frame 22 is connected with the base 21, ensuring that the swing rod 3 can smoothly reciprocate and simulate the real target movement state.

[0061] Further, the starting end of the slide rail 1 is also provided with a stop frame 11, the end of the stop frame 11 is provided with an electromagnetic buckle 111, the electromagnetic buckle 111 is suitable for abutting against the base 21 of the sliding trolley 2, and is used for controlling the release of the sliding trolleys 2 one by one; the upper end of the stop frame 11 is provided with a rear door 112 and a rear buckle 113, the rear buckle 113 is suitable for detachably installing the rear door 112 on the stop frame 11, and facilitates the placement of the sliding trolley 2.

[0062] In this embodiment, the lower end of the stop frame 11 is provided with an electromagnetic buckle 111, which can abut against the base 21 of the sliding trolley 2, thereby realizing the one-by-one release control of the sliding trolley 2, and effectively improving the efficiency and safety of the training.

[0063] Specifically, the starting end of the slide rail 1 is provided with a stop frame 11.
