Description

Technical Field

[0001] The present invention relates to the technical field of intelligent security devices, and specifically to an intelligent security patrol robot. Background Art

[0002] An intelligent security patrol robot is a high-tech device integrating artificial intelligence, Internet of Things, and automation technologies, designed specifically to improve security efficiency. The robot is equipped with a high-definition camera, sensors, and a monitoring system with adjustable height, capable of autonomous patrol, real-time monitoring, and recording of abnormal situations. Through functions such as face recognition, infrared night vision, and target tracking, the robot can accurately identify potential threats and issue alarms in a timely manner. Applicable to places such as shopping malls, communities, factories, and campuses, the intelligent security patrol robot effectively reduces labor costs and improves the level of security management, contributing to the construction of a smart security system.

[0003] The intelligent security patrol robot uses a camera to monitor and photograph the surrounding environment. The camera is usually installed at the head position of the robot. By driving the robot with a walking component to frequently adjust its position, the purpose of increasing the shooting range is achieved. However, frequent movement of the position requires more energy to drive, resulting in increased energy consumption of the patrol robot. Moreover, it is not convenient to adjust the height and orientation of the camera with only one drive source, reducing the patrol efficiency of the intelligent security patrol robot. For this reason, we have proposed an intelligent security patrol robot. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent security patrol robot to solve the problems raised in the above background art.

An adjustment mechanism is arranged in an internal slot at the top of the frame body. A column is fixed above the frame body near the adjustment mechanism. The turntable is movably sleeved outside the column. A screw rod and a drive shaft are installed in the internal slot of the frame body near the column through bearings, and one end of the screw rod is located in the internal slot of the column. Both the screw rod and the drive shaft are connected to the adjustment mechanism. The adjustment mechanism includes a first bevel gear, a second bevel gear, a locking rod, a first electric push rod, a dual-axis motor, a third bevel gear, and a fourth bevel gear. The bottom end of the screw rod is fixedly sleeved with the fourth bevel gear. A third bevel gear is meshed and connected to one side of the fourth bevel gear. The bottom end of the drive shaft is fixedly sleeved with the second bevel gear. A first bevel gear is provided on one side of the second bevel gear. A dual-axis motor is connected between the first bevel gear and the third bevel gear through a coupling. A sliding frame is sleeved outside the dual-axis motor through bolts. Locking rods are fixed at both the upper and lower ends of the sliding frame.

[0006] Preferably, a guiding groove is formed in the inner wall of the frame body close to the sliding carriage, and the sliding carriage is slidably connected to the guiding groove, and the locking rods are arranged in opposite directions.

[0007] Preferably, the locking rod is L-shaped, a first electric push rod is connected to the bottom end of the sliding carriage, and a U-shaped frame is installed below the first electric push rod.

[0008] Preferably, a driving disc is fixedly connected to the end of the driving shaft away from the second bevel gear, the driving disc is meshed with the turntable, and telescopic rods are fixed at both ends of the surface of the turntable.

[0009] Preferably, the top end of the telescopic rod is fixedly connected to a disc, a shaft sleeve is fixed in the middle of the disc, a camera assembly is installed on the surface of the disc, and a lifting rod is threadedly sleeved at one end of the screw rod close to the inside of the column.

[0010] Preferably, the top end of the lifting rod is movably sleeved with the shaft sleeve, sliding grooves are formed in both inner walls of the column, and both ends of the lifting rod are slidably connected to the sliding grooves.

[0011] Preferably, a radar is installed on one side of the frame body through a bracket, traveling assemblies are installed on both sides of the bottom end of the frame body, and a collision avoidance sensor is installed at one end of the frame body.

[0012] Preferably, a power supply is installed on the bottom frame of the frame body, and a supporting plate is fixedly installed inside the frame body above the power supply.

[0013] Preferably, an auxiliary mechanism is installed on the outer side of the frame body close to the supporting plate. The auxiliary mechanism includes a side plate, a second electric push rod, a blocking door and a rotating seat, and the side plate is fixedly installed on the outer side of the frame body.

[0014] Preferably, a blocking door is movably connected to the inner wall of the frame body close to the side plate through a rotating seat, and a second electric push rod is connected between the side plate and the blocking door through a movable shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: for this intelligent security patrol robot, the dual-axis motor in the adjustment mechanism can drive the third bevel gear and the first bevel gear to be engaged with the fourth bevel gear and the second bevel gear respectively by moving up and down, so as to adjust the longitudinal position and orientation of the camera assembly respectively. At the same time, the locking rod limits the object that is not driven to prevent accidental start-up. Without moving the whole robot, the shooting range can be increased and unnecessary energy consumption can be reduced. When using the intelligent security patrol robot, items or tools can be carried through the supporting plate and the auxiliary mechanism, which provides an auxiliary function for security work and improves the flexibility and working efficiency of the intelligent security patrol robot.

[0016] 1. For this intelligent security patrol robot, a dual-axis motor drives a third bevel gear to rotate clockwise or counterclockwise. The third bevel gear is meshed with a fourth bevel gear, causing the third bevel gear to drive the fourth bevel gear to rotate. Subsequently, the fourth bevel gear drives a screw rod to rotate, and then a lifting rod moves upward or downward on the outer side of the screw rod. The traction sleeve at the top of the lifting rod drives a disc to move up and down, and both ends of the disc drive a telescopic rod to expand and contract, which can provide a guiding function for the longitudinal movement of the disc, conveniently and quickly adjust the height of the camera assembly, increase the longitudinal shooting range of the camera assembly, and improve the patrol efficiency of the intelligent security patrol robot;

[0017] 2. For this intelligent security patrol robot, directly shorten the first electric push rod and traction carriage to move downward in the guiding groove. At the same time, the carriage drives the dual-axis motor to move downward. Subsequently, the dual-axis motor drives the third bevel gear to move downward and disengage from the tooth opening of the fourth bevel gear until the dual-axis motor drives the first bevel gear to be meshed with the second bevel gear. At the same time, the carriage drives the upper locking rod to enter the tooth opening of the fourth bevel gear, and the lower locking rod disengages from the tooth opening of the second bevel gear. The locking rod can restrict the rotation of the fourth bevel gear to prevent the fourth bevel gear from rotating accidentally. Subsequently, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives a drive disc to rotate through a drive shaft, the drive disc drives a turntable to rotate, and the turntable then makes the telescopic rod drive the sleeve to rotate at the end of the lifting rod, thereby making the disc rotate. It can photograph and detect the surrounding environment without driving the walking assembly, and only uses one dual-axis motor to drive the camera assembly to perform longitudinal adjustment and azimuth adjustment respectively, reducing energy consumption, increasing the shooting range, and improving the practicality of the intelligent security patrol robot;

[0018] 3. For this intelligent security patrol robot, start the second electric push rod to shorten it. Subsequently, the second electric push rod traction shutter, causing one end of the shutter to rotate around the rotating seat, can open the shutter, facilitating the staff to place tools or boxed items on the support plate. After placing the boxed items or tools, the shutter can be blocked on one side of the support plate to prevent the boxed items or tools from slipping. Carrying items by the intelligent security patrol robot can improve the flexibility of the intelligent security patrol robot. Description of the Drawings

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 - 6 , the present invention provides a technical solution: an intelligent security patrol robot, including a frame body 1 and a turntable 11. An adjusting mechanism 6 is provided in the built-in groove at the top of the frame body 1. A radar 4 is installed on one side of the frame body 1 through a bracket. Traveling assemblies 3 are installed on both sides of the bottom end of the frame body 1. An anti-collision sensor 14 is installed at one end of the frame body 1. A power supply 2 is installed on the bottom frame of the frame body 1.

[0032] Please refer to Figure 1 , Figure 2 andFigures 5 - 10 Above the frame body 1 near the adjusting mechanism 6, a column 17 is fixedly installed. The turntable 11 is movably sleeved outside the column 17. In the built-in groove of the frame body 1 near the column 17, a screw rod 10 and a driving shaft 20 are installed through bearings. One end of the screw rod 10 is located in the built-in groove of the column 17. Both the screw rod 10 and the driving shaft 20 are connected to the adjusting mechanism 6. The adjusting mechanism 6 includes a first bevel gear 601, a second bevel gear 602, a locking rod 603, a first electric push rod 604, a dual-axis motor 605, a third bevel gear 606, and a fourth bevel gear 607. The bottom end of the screw rod 10 is fixedly sleeved with the fourth bevel gear 607. One side of the fourth bevel gear 607 is meshed with the third bevel gear 606. The bottom end of the driving shaft 20 is fixedly sleeved with the second bevel gear 602. One side of the second bevel gear 602 is provided with the first bevel gear 601. A dual-axis motor 605 is connected between the first bevel gear 601 and the third bevel gear 606 through a coupling. The outside of the dual-axis motor 605 is sleeved with a sliding frame 19 through bolts. One end of the screw rod 10 near the inside of the column 17 is threadedly sleeved with a lifting rod 21. The top end of the lifting rod 21 is movably sleeved with a shaft sleeve 16. Both inner walls of the two sides of the column 17 are provided with sliding grooves 22. Both ends of the lifting rod 21 are slidably connected with the sliding grooves 22. The first bevel gear 601 and the second bevel gear 602 are meshed with each other.

[0033] During specific implementation, when the intelligent security patrol robot is moving, the height of the camera can be adjusted within the original camera shooting range to meet the longitudinal camera patrol work. By starting the dual-axis motor 605 to drive the third bevel gear 606 to rotate clockwise or counterclockwise, the third bevel gear 606 is meshed with the fourth bevel gear 607, so that the third bevel gear 606 drives the fourth bevel gear 607 to rotate. Subsequently, the fourth bevel gear 607 drives the screw rod 10 to rotate. The screw rod 10 is threadedly meshed with the lifting rod 21, so that the lifting rod 21 moves upward or downward outside the screw rod 10. At the same time, both ends of the lifting rod 21 slide up and down in the sliding grooves 22. The top end of the lifting rod 21 pulls the shaft sleeve 16 to drive the disc 13 to move up and down. And both ends of the disc 13 drive the telescopic rod 12 to expand and contract, which can provide a guiding effect for the longitudinal movement of the disc 13, can conveniently and quickly adjust the height of the camera assembly 7, increase the longitudinal shooting range of the camera assembly 7, and improve the patrol efficiency of the intelligent security patrol robot.

[0034] Please refer to Figure 1 、 Figure 2 and Figures 5 - 10, locking rods 603 are fixed to both the upper and lower ends of the carriage 19. A guiding groove 15 is formed in the inner wall of the frame body 1 close to the carriage 19, and the carriage 19 is slidably connected to the guiding groove 15. The locking rods 603 are arranged in opposite directions and are L-shaped. A first electric push rod 604 is connected to the bottom end of the carriage 19. A U-shaped frame 8 is installed below the first electric push rod 604. The end of the drive shaft 20 away from the second bevel gear 602 is fixedly connected to a drive disk 18. The drive disk 18 is meshed with the turntable 11. Two telescopic rods 12 are fixed to both ends of the surface of the turntable 11. The top ends of the telescopic rods 12 are fixedly connected to a disk 13. A sleeve 16 is fixed to the middle of the disk 13. An imaging assembly 7 is installed on the surface of the disk 13. Tooth blocks are annularly distributed outside the turntable 11.

[0035] During specific implementation, since a driving member is usually provided to adjust the height of the camera, the longitudinal shooting range of the camera is increased. However, when the intelligent security patrol robot needs to photograph and detect the surrounding environment, it is necessary to drive the crawler to change the orientation of the patrol robot, resulting in energy consumption. The first electric push rod 604 can be directly shortened to pull the carriage 19 to move downward in the guiding groove 15. At the same time, the carriage 19 drives the double-shaft motor 605 to move downward. Subsequently, the double-shaft motor 605 drives the third bevel gear 606 to move downward and disengage from the tooth opening of the fourth bevel gear 607 until the double-shaft motor 605 drives the first bevel gear 601 to be meshed with the second bevel gear 602. At the same time, the carriage 19 drives the upper locking rod 603 to enter the tooth opening of the fourth bevel gear 607, and the lower locking rod 603 disengages from the tooth opening of the second bevel gear 602. The locking rod 603 can limit the rotation of the fourth bevel gear 607 to prevent the fourth bevel gear 607 from rotating accidentally. Subsequently, the first bevel gear 601 drives the second bevel gear 602 to rotate. The second bevel gear 602 drives the drive disk 18 to rotate through the drive shaft 20. The drive disk 18 is meshed with the turntable 11, so that the drive disk 18 drives the turntable 11 to rotate. The turntable 11 then makes the telescopic rod 12 drive the sleeve 16 to rotate at the end of the lifting rod 21. Further, the sleeve 16 drives the disk 13 to rotate. Without affecting the longitudinal position of the imaging assembly 7, the orientation of the imaging assembly 7 can also be adjusted. The surrounding environment can be photographed and detected without driving the traveling assembly 3. Moreover, only one double-shaft motor 605 is used to drive the imaging assembly 7 to perform longitudinal adjustment and orientation adjustment respectively, reducing energy consumption, increasing the shooting range, and improving the practicability of the intelligent security patrol robot.

[0036] Please refer to Figures 1 - 4, a supporting plate 5 is fixedly installed inside the frame body 1 above the power supply 2, and an auxiliary mechanism 9 is installed outside the frame body 1 near the supporting plate 5. The auxiliary mechanism 9 includes a side plate 901, a second electric push rod 902, a door 903 and a rotating seat 904. The side plate 901 is fixedly installed outside the frame body 1, and the door 903 is movably connected to the inner wall of the frame body 1 near the side plate 901 through the rotating seat 904. A second electric push rod 902 is connected between the side plate 901 and the door 903 through a movable shaft. A plurality of anti-slip lines are pasted on the surface of the supporting plate 5.

[0037] During specific implementation, since the existing security patrol robot does not have a structure for placing box-shaped items, the task flexibility is relatively low. When it is necessary to carry some auxiliary tools or box-shaped items through the security patrol robot, the second electric push rod 902 can be activated to shorten the second electric push rod 902. Subsequently, the second electric push rod 902 pulls the door 903, causing one end of the door 903 to rotate around the rotating seat 904, so that the door 903 can be opened, facilitating the staff to place tools or box-shaped items on the supporting plate 5. The surface of the supporting plate 5 is provided with anti-slip lines, which can increase the friction between the box-shaped items or tools and the supporting plate 5. After placing the box-shaped items or tools, the door 903 can be blocked on one side of the supporting plate 5 to prevent the box-shaped items or tools from slipping. Carrying items through the intelligent security patrol robot can improve the flexibility of the intelligent security patrol robot.

[0038] In summary, when using this intelligent security patrol robot, the walking assembly 3 drives the frame body 1 to move forward or backward through the crawler to detect the surrounding environment. The radar 4 assists in navigation and route planning. The anti-collision sensor 14 detects obstacles to prevent collisions. The camera assembly 7 takes pictures of the surrounding environment. The camera assembly 7 can be longitudinally adjusted and azimuthally adjusted through the adjustment mechanism 6, which can increase the shooting range without moving the entire robot. When using the intelligent security patrol robot, items or tools can be carried through the supporting plate 5 and the auxiliary mechanism 9, providing an auxiliary role for security work and improving the flexibility and work efficiency of the intelligent security patrol robot. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
