With the progress of urbanization and the continuous increase in urban area, the police force required for public security is increasing, resulting in an increase in public security costs. In order to avoid this, security patrol robots will be used to replace the police for daily patrols.

DETAILED DESCRIPTION

[0041] See also Figure 3 The steering device 2 includes a bogie 21, a rack 22 is fixedly installed on the back of the bogie 21, a first connecting rod 23 is fixedly installed on the back of the bogie 21 at positions on both sides of the rack 22, a connecting beam 24 is fixedly installed at one end of the first connecting rod 23, and a contact plate 25 is fixedly installed on the top of the connecting beam 24.

[0042] See also Figure 2-Figure 3 The top of the contact plate 25 is provided with an inclined surface, the height in the middle of the top of the contact plate 25 is lower than the heights at both ends, and the top of the contact plate 25 is in contact with the rocking device 4.

[0043] See also Figure 2-Figure 3 , the steering gear 3 is engaged with the rack 22.

[0044] See also Figure 2-Figure 3 The rocking device 4 includes a rocking bracket 41, which is fixedly mounted at the middle position of the bottom of the inner cavity of the shell 10. The top of the rocking bracket 41 is movably sleeved with a rocking arm 42. One end of the rocking arm 42 contacts the top of the contact plate 25, and the other end of the rocking arm 42 contacts the transmission device 7.

[0045] See also Figure 2 and Figure 4 The power device 6 includes a driving wheel 61 and a power machine 62. The driving wheel 61 is movably mounted on the housing 10. The power machine 62 drives the driving wheel 61 to rotate. A reversing device 63 is fixedly mounted on the outer surface of the driving wheel 61. The reversing device 63 is engaged with the transmission device 7.

[0046] When the traveling speed of the device is greater, the turning speed of the device is faster. At this time, the rotation speed of the driving wheel 61 increases. Similarly, the rotation speed of the reversing device 63 also increases. After the transmission device 7 rotates as a whole, the torque output to the monitoring device 15 also increases, thereby increasing the rotation speed of the monitoring device 15. This enables the monitoring device 15 to increase its rotation speed to compensate for its own offset during high-speed turning, further improving the automation of the device adjustment and reducing the difficulty of operation.

[0047] See also Figure 3 and Figure 5 The reversing device 63 includes a sleeve 631, and a first bevel gear 632 is fixedly sleeved on the outer surface of the sleeve 631 near both ends. The two first bevel gears 632 are arranged in a symmetrical manner. A connecting seat 633 is fixedly sleeved on the outer surface of the sleeve 631 near the middle. A forked bracket 634 is fixedly installed on the front side of the connecting seat 633, and a connecting shaft 635 is fixedly installed on the inner side of the forked bracket 634 near the front end. A connecting arm 636 is movably installed on the outer surface of the connecting shaft 635 near the middle. Buffer springs 637 are clamped at both ends of the connecting arm 636, one end of the buffer spring 637 is connected to the inner side of 633, and the front end of the connecting arm 636 is fixedly connected to the connecting beam 24.

[0048] See also Figure 1-Figure 2 and Figure 6 The transmission device 7 includes a reduction device 71, a driving device 72, a first double-headed transmission rod 73 and a second double-headed transmission rod 74. The reduction device 71 is in contact with the driving device 72. The two ends of the first double-headed transmission rod 73 are respectively engaged with the driving device 72 and the first bevel gear 632. The two ends of the second double-headed transmission rod 74 are respectively engaged with the driving device 72 and the monitoring device 15. The first double-headed transmission rod 73 and the second double-headed transmission rod 74 are both connected to the inner wall of the outer shell 10 through ribs at both ends.

[0049] When the device is turning and the connecting beam 24 moves to the left or right, it will drive the connecting arm 636 to move synchronously, and the sliding sleeve 631 will be driven to the left and right under the transmission action of the connecting shaft 635, the forked bracket 634 and the connecting seat 633. When moving to the left, the first bevel gear 632 on the left is engaged with the first double-headed transmission rod 73. When moving to the right, the first bevel gear 632 on the right is engaged with the first double-headed transmission rod 73, thereby achieving the effect of changing the rotation direction, ensuring that when the device turns left, the monitoring device 15 can turn right to compensate, and when the device turns right, the monitoring device 15 can turn left to compensate.

[0050] See also Figure 1 and Figure 7-Figure 8When the lever 714 is in the unlocking position, the lever 715 is in the unlocking position, and the spring 718 is in the unlocking position, so that the lever 714 can be unlocked and the spring 718 can be unlocked.

[0051] When the device is in a normal patrol state and the monitoring device 15 is not required to compensate for the steering offset, the telescopic machine 719 can be controlled to extend the output end of the telescopic machine 719 and push up the telescopic plate 714, so that the lock buckle 716 remains locked with the ratchet teeth on the outer surface of the ratchet 726. At this time, the monitoring device 15 cannot perform rotation compensation, which further improves the practicality of the device.

[0052] See also Figure 8 The driving device 72 includes a rotating shaft 721, and ribs 722 are provided at both ends of the rotating shaft 721. The back of the ribs 722 is connected to the inner wall of the shell 10. A second bevel gear 723 is fixedly provided on the outer surface of the rotating shaft 721 near the right side, and an active disk 724 is fixedly provided on the outer surface of the rotating shaft 721 near the middle. A passive disk 725 is movably provided on the outer surface of the rotating shaft 721 at the left side of the active disk 724. A ratchet 726 is provided on the outer surface of the passive disk 725, and a third bevel gear 727 is fixedly installed on the right side of the passive disk 725.

[0053] See also Figure 1-Figure 2 , Figure 4 , Figure 6-Figure 8 and Figure 13 The second bevel gear 723 is engaged with the first double-headed transmission rod 73 , and the third bevel gear 727 is engaged with the second double-headed transmission rod 74 .

[0054] During the steering process of the device, the steering gear 3 outputs torque and drives the bogie 21 to steer through the gear transmission. At the same time, the rack 22 and the contact plate 25 will also move laterally. Since the height in the middle of the top of the contact plate 25 is lower than the height at both ends, and the top of the contact plate 25 is in contact with the rocking device 4, during the lateral movement of the contact plate 25, the height of the end of the rocking arm 42 in contact with the contact plate 25 increases, while the height of the end in contact with the bottom of the telescopic plate 714 decreases. Under the action of the elastic force of the compression spring 713, the telescopic plate 714 moves downward, so that the lock buckle 716 and the outer surface of the ratchet 726 are unlocked. At this time, the passive magnetic disk 725 can rotate along its own axis as the rotation center. When the power machine 62 drives the driving wheel 61 and the reversing device 63 to rotate, the reversing device 63 transmits the rotational torque through the first double-headed transmission rod 73 The third bevel gear 727 transmits the rotational torque to the fourth bevel gear 154 through the second double-headed transmission rod 74, thereby realizing the autonomous rotation of the monitoring device 15, and realizing that the monitoring device 15 can rotate in the opposite direction during the turning process of the device, thereby compensating for the offset of the monitoring device 15 when the device turns, and ensuring that the monitoring device 15 can always be aligned with the target direction during the turning process of the device, thereby avoiding the problem that the monitoring device 15 offsets when the device turns and cannot be aligned with the target, resulting in the loss of the target, thereby improving the stability of the device during use.

[0055] The active disk 724 and the passive disk 725 are driven by magnetic non-contact drive. When turning, the greater the amplitude, the greater the moving distance of the rack 22. Similarly, the greater the moving distance of the connecting beam 24 and the contact plate 25, the higher the height of the position where the top of the contact plate 25 contacts the swing bracket 41, and the lower the height of the end of the swing bracket 41 that contacts the bottom of the telescopic plate 714, so that the contact area between the friction plate 718 and the ratchet 726 is reduced, and the deceleration effect of the friction plate 718 on the ratchet 726 is reduced, so that the rotation speed of the passive disk 725 is increased, thereby increasing the rotation amplitude of the monitoring device 15, and realizing that the greater the rotation amplitude of the device, the greater the amplitude of the reverse rotation compensation of the monitoring device 15, thereby improving the automation of the adjustment of the device and reducing the difficulty of operation.

[0056] See also Figure 1 , Figure 7-11The adjusting device 8 includes a rotating handle 81, a threaded rod 82 is fixedly installed on one side of the rotating handle 81, the outer surface of the threaded rod 82 is provided with a thread and cooperates with the right side of the inner wall of the shell 10, one end of the threaded rod 82 is fixedly installed with a second connecting rod 83, one end of the second connecting rod 83 is fixedly installed with a stroke sleeve 84, an adjusting spring 85 is movably installed inside the stroke sleeve 84, the end of the adjusting spring 85 is clamped with a pressure rod 86, one end of the pressure rod 86 is connected to the bottom of the inner cavity of the stroke sleeve 84, and the front end of the adjusting spring 85 is fixedly installed with a pressure plate 87, which is in contact with the side plate 717. When the device is in the process of steering, the monitoring When over-compensation or insufficient compensation occurs during the rotation compensation of the device 15, the operator can hold the rotating handle 81 and rotate it. The outer surface of the threaded rod 82 is provided with threads and cooperates with the right side of the inner wall of the shell 10, so that the rotating handle 81 can adjust the distance between the second connecting rod 83 and the side plate 717 during the rotation, thereby changing the initial elastic force of the adjustment spring 85 and the friction force between the friction plate 718 and the ratchet 726, thereby changing the rotation amplitude of the monitoring device 15, avoiding the problem of over-compensation or insufficient compensation during the rotation compensation of the monitoring device 15, and improving the practicality of the device.

[0057] See also Figure 1 , Figure 6 and Figure 13 The monitoring device 15 includes a rotating sleeve 151, which is movably connected to the top of the housing 10. A steering gear 152 is fixedly installed inside the rotating sleeve 151, and a monitor 153 is fixedly installed at one end of the output shaft of the steering gear 152. A fourth bevel gear 154 is fixedly installed at the bottom of the rotating sleeve 151 and engages with the second double-headed transmission rod 74.

[0058] The method of use of the present invention is as follows:

[0059] During use, when the device is turning, the steering gear 3 outputs torque and drives the bogie 21 to turn through the gear transmission. At the same time, the rack 22 and the contact plate 25 will also move laterally. During the lateral movement of the contact plate 25, the height of the end of the rocker arm 42 in contact with the contact plate 25 increases, while the height of the end in contact with the bottom of the telescopic plate 714 decreases. Under the action of the elastic force of the compression spring 713, the telescopic plate 714 moves downward, so that the lock buckle 716 and the outer surface of the ratchet 726 are unlocked. At this time, the passive magnetic disk 725 can rotate along its own axis as the rotation center. When the power machine 62 drives the driving wheel 61 and the reversing device 63 to rotate, the reversing device 63 transmits the rotation torque through the first double-headed transmission rod 7 3 is transmitted to the second bevel gear 723, thereby driving the rotating shaft 721 and the active disk 724 to rotate, and the passive disk 725 and the third bevel gear 727 rotate synchronously, and the third bevel gear 727 transmits the rotational torque to the fourth bevel gear 154 through the second double-headed transmission rod 74, thereby realizing the autonomous rotation of the monitoring device 15, realizing that when the device is moving and turning, the monitoring device 15 can rotate in the opposite direction to compensate for the offset of the monitoring device 15 when the device turns. When the connecting beam 24 moves to the left or right, it will drive the connecting arm 636 to move synchronously, and under the transmission action of the connecting shaft 635, the forked bracket 634 and the connecting seat 633, the sliding sleeve 631 is driven to the left and right. When the vehicle moves to the right, the first bevel gear 632 on the left side meshes with the first double-headed transmission rod 73, and when the vehicle moves to the right, the first bevel gear 632 on the right side meshes with the first double-headed transmission rod 73, thereby achieving the effect of changing the direction of rotation. When the device turns left, the monitoring device 15 can turn right to compensate, and when the device turns right, the monitoring device 15 can turn left to compensate. When turning, the greater the amplitude, the greater the movement distance of the rack 22. Similarly, the greater the movement distance of the connecting beam 24 and the contact plate 25, the higher the height of the position where the top of the contact plate 25 contacts the rocking bracket 41, and the lower the height of the end of the rocking bracket 41 that contacts the bottom of the telescopic plate 714, so that the friction The contact area between the friction plate 718 and the ratchet 726 is reduced, and the deceleration effect of the friction plate 718 on the ratchet 726 is reduced, so that the rotation speed of the passive magnetic disk 725 is increased, thereby increasing the rotation amplitude of the monitoring device 15, and realizing that the greater the rotation amplitude of the device, the greater the amplitude of the reverse rotation compensation of the monitoring device 15. When the traveling speed of the device is greater, the turning speed of the device is faster. At this time, the rotation speed of the drive wheel 61 is increased. Similarly, the rotation speed of the reversing device 63 is also increased. After the overall rotation of the transmission device 7, the torque output to the monitoring device 15 is also increased, thereby increasing the rotation speed of the monitoring device 15, and realizing that when the device is turning at high speed, the monitoring device 15 can increase the rotation speed to compensate for its own offset.

[0060] When the device is turning and over-compensation or insufficient compensation occurs during the rotation compensation of the monitoring device 15, the operator can hold the rotating handle 81 and rotate it. The outer surface of the threaded rod 82 is provided with threads and cooperates with the right side of the inner wall of the shell 10, so that the rotating handle 81 can adjust the distance between the second connecting rod 83 and the side plate 717 during the rotation, thereby changing the initial elastic force of the adjustment spring 85 and the friction force between the friction plate 718 and the ratchet 726, thereby changing the rotation amplitude of the monitoring device 15.

[0061] When the device is in a normal patrol state and the monitoring device 15 does not need to compensate for the steering offset, the telescopic machine 719 can be controlled to extend the output end of the telescopic machine 719 and push up the telescopic plate 714, so that the lock buckle 716 remains locked with the ratchet teeth on the outer surface of the ratchet 726. At this time, the monitoring device 15 cannot perform rotation compensation.
