Technical Field

[0001] The present application relates to the field of inspection equipment, and in particular to a liftable camera for installation on an inspection robot. Background Art

[0002] Inspection robots are robots that can automatically walk along preset routes and conduct patrol inspections. They are widely used in many fields such as industry, commerce, and public security, providing effective technical means to maintain and ensure the stable operation of various environments.

[0003] The inspection robot is equipped with a security monitoring system, and the camera in this system is fixed. However, in some special situations, such as when the monitoring area is large or the height of the monitored object varies, the fixed camera position is not sufficient. Therefore, a camera mechanism that can be raised and lowered is needed to adjust the camera height as needed. Utility Model Content

[0004] In order to achieve the lifting and lowering of the camera and improve the height monitoring range of the inspection robot, the present application provides a liftable camera for installation on the inspection robot.

[0005] The present application provides a liftable camera for installation on an inspection robot using the following technical solution:

[0006] A liftable camera for installation on an inspection robot comprises a base arranged on a body, a first arm hinged on the base, a second arm hinged on the first arm, a camera provided on the second arm, a slide slidably provided on the base, a first push rod hinged on the slide, the first push rod hinged on the first arm, the first push rod extending toward the second arm, a second push rod hinged on the first push rod, the second push rod hinged on the second arm, and a control device for controlling the movement of the base is provided on the base.

[0007] By adopting the above technical solution, the control device drives the slide to move, and then drives the first push rod and the push rod to flip, so as to control the folding or opening of the first arm and the second arm, and then drives the camera to rise and fall, making it easy to adjust the height of the camera so that the operator can adjust the monitoring range of the camera according to actual needs.

[0008] Optionally, the control device includes a screw rotatably connected to the base, the screw passes through the slide and is threadedly connected to the slide, and a motor is provided on the base, and the motor is transmission-connected to the screw.

[0009] By adopting the above technical solution, the motor drives the screw to rotate, which in turn drives the slide to move. This control method not only improves the convenience of operation, but also makes the raising and lowering of the camera more precise and stable.

[0010] Optionally, the first arm and the second arm have the same structure, the first arm includes two first rods that are parallel to each other and of equal length, the second arm includes two second rods that are parallel to each other and of equal length, one end of the two first rods is hinged to the base, the other ends of the two first rods are connected through a connecting seat, and the other ends of the two first rods are both hinged to the connecting seat, one end of the two second rods is hinged to the connecting seat, and the other ends of the two second rods are both hinged to the camera.

[0011] By adopting the above technical solution, the first arm is composed of two first rods that are parallel to each other and of equal length, and the second arm is composed of two second rods that are parallel to each other and of equal length. Both the first arm and the second arm are parallelogram structures, so that the angle of the camera does not change during the flipping process of the first arm and the second arm.

[0013] By adopting the above technical solution, when the camera is retracted, the limit seat can be stuck in the limit groove, thereby limiting the movement of the camera and improving the stability of the camera in the retracted state.

[0014] Optionally, the driving device includes a first elastic member, which is connected between the base and the push plate and applies a force to the push plate in the direction of the push block, and a limit block is provided in the base for limiting the movement of the push plate;

[0015] The sliding seat includes a moving seat slidably arranged in the base and a push block slidably arranged on the moving seat.

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The embodiment of the present application discloses a liftable camera for installation on an inspection robot. Figure 1 and Figure 2 The liftable camera for mounting on an inspection robot includes a body 1. In the embodiment of the present application, body 1 is the inspection robot, which serves as the mounting platform for the entire mechanism. A base 11 is fixedly mounted on the lower surface of body 1. One end of a first arm 12 is hingedly connected to the bottom of base 11. The other end of the first arm 12 is hingedly connected to a connecting base 18. A second arm 14 is mounted on the connecting base 18. One end of the first arm 12 is hingedly connected to the connecting base 18. The other end of the second arm 14 is fixedly connected to a mounting base 16. A camera 17 is fixedly mounted below the mounting base 16.

[0027] The first arm 12 and the second arm 14 have identical structures. The first arm 12 comprises two parallel first support rods 13, while the second arm 14 comprises two parallel second support rods 15. Each first support rod 13 is hinged to the base 11 at one end and to the connecting base 18 at the other end. Furthermore, the two first support rods 13 have identical dimensions and structures, forming a parallelogram structure. Each second support rod 15 has one end hinged to the connecting base 18 and the other end hinged to the mounting base 16. Furthermore, the two second support rods 15 have identical dimensions and structures, forming a parallelogram structure.

[0028] The camera 17 is connected by two parallelogram structures so that the angle of the camera 17 is kept fixed and does not tilt during the lifting process.

[0029] A slide 2 is slidably mounted on the base 11. A first push rod 3 is hingedly mounted on the slide 2. Near the middle of its length, the first push rod 3 is hingedly mounted to one of the first push rods 3. The end of the first push rod 3, away from the slide 2, extends toward a second push rod 31 and is connected to the second support rod 15 via the second push rod 31. One end of the second push rod 31 is hinged to the first support rod 13, and the other end of the second push rod 31 is hinged to one of the second support rods 15. Due to the linkage between the first push rod 3 and the second push rod 31, when the slide 2 moves toward the first support arm 12, the camera 17 gradually extends. When the slide 2 moves away from the first arm 12, the camera 17 gradually retracts.

[0030] like Figure 2 and Figure 3The base 11 is provided with a control device 4 for controlling the movement of the slide 2 on the base 11. The control device 4 mainly includes a screw 41 and a motor 42. The screw 41 is rotatably connected to the base 11, and the screw 41 passes through the slide 2 and is threadedly connected to the slide 2. When the screw 41 rotates, the slide 2 can slide on the base 11, thereby driving the camera 17 to extend and retract. The motor 42 is provided on the base 11 and is connected to the screw 41 via a coupling (not shown in the figure) to drive the rotation of the screw 41.

[0031] like Figure 2 and Figure 4 In order to improve the stability of the camera 17 on the base 11 when the camera 17 is retracted, a limiting structure is provided on the base 11 for fixing the camera 17. The limiting structure includes an upper limiting seat 51 that is slidably disposed on the base 11, and a clamping block is provided on the limiting seat 51. The mounting base 16 is provided with a limiting groove 52 for the limiting seat 51 to engage. When the camera 17 is in the retracted state, the clamping block on the limiting seat 51 is aligned with the limiting groove 52. The operator can control the clamping block on the limiting seat 51 to engage the limiting groove 52, thereby achieving a reinforcement effect on the camera 17.

[0032] like Figure 2 and Figure 3 A push plate 5 is slidably provided on the base 11. The push plate 5 is located on the side of the slide 2 away from the first arm 12. The push plate 5 is connected to the limit seat 51 via a connecting rod 53. The limit seat 51 is driven to move by controlling the movement of the push plate 5. A driving device 6 for controlling the movement of the push plate 5 is provided on the base 11. The driving device 6 includes a first elastic member 62 and a limit block 61. The limit block 61 is provided on the base 11 and is used to limit the travel of the push plate 5 toward the first arm 12. The first elastic member 62 is connected between the base 11 and the push plate 5 and pushes the push plate 5 toward abutting the limit block 61.

[0033] The slide 2 includes a moving seat 21 that is slidably arranged in the base 11 and a push block 22 that is slidably arranged on the moving seat 21. The moving seat 21 is threadedly connected to the screw 41. When the screw 41 rotates, the moving seat 21 can slide in the base 11. A guide rod 23 is provided on the side of the moving seat 21 facing the first arm 12. The push block 22 is slidably sleeved on the guide rod 23. An end plate 25 is provided on the end of the guide rod 23 away from the moving seat. The slide 2 is slidably arranged between the end plate 25 and the moving seat 21, and a second elastic member 24 is provided on the guide rod 23 between the end plate 25 and the push block 22. The second elastic member 24 is used to push the push block 22 toward the moving seat 21. The end of the first push rod 3 is hinged to the push block 22, so that the movement of the push block 22 can drive the rotation of the first push rod 3.

[0034] When the movable base 21 moves, the second elastic member 24 drives the push block 22 to move, thereby driving the first push rod 3 and the second push rod 31 to flip, thereby driving the first arm 12 and the second arm 14 to fold relative to each other, achieving the effect of extending and retracting the camera 17. In addition, the movable base 21 can also be used to push the push plate 5 away from the limit block 61, thereby driving the limit base 51 to slide.

[0035] The first elastic member 62 and the second elastic member 24 can be made of elastic materials such as springs, tension springs, and elastic bands. In the embodiment of the present application, the first elastic member 62 and the second elastic member 24 are both springs.

[0036] The principle of the embodiment of the present application is as follows: when the camera 17 is in the extended state, the movable seat 21 is close to the first arm 12 and away from the push plate 5, the push block 22 is pressed against the movable seat 21 under the elastic force of the second elastic member 24, and the push plate 5 is pressed against the limit block 61 under the elastic force of the first elastic member 62.

[0037] During the process of retracting the camera 17, the motor 42 starts to drive the screw 41 to rotate, and drives the movable seat 21 to gradually move toward the push plate 5. During this process, the first push rod 3 and the second push rod 31 are folded, driving the first arm 12 and the second arm 14 to fold each other, and then driving the camera 17 to move toward the base 11 to achieve the retraction effect.

[0038] When the camera 17 moves to the mounting seat 16 and abuts against the base 11 , the block on the limiting seat 51 is aligned with the limiting groove 52 on the mounting seat 16 , and the moving seat 21 abuts against the push plate 5 .

[0039] The motor 42 continues to drive the screw 41 to rotate, driving the movable seat 21 to overcome the elastic force of the first elastic member 62 and to move, and push the push plate 5 to move away from the limit block 61. The push plate 5 overcomes the elastic force of the second elastic member 24 and moves, and drives the card block on the limit seat 51 to be inserted into the limit groove 52, thereby fixing the position of the camera 17.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
