Description

Technical Field

[0001] The present invention relates to the technical field of patrol equipment, and specifically to a patrol robot with an anti-collision pan-tilt lifting function. Background Art

[0002] A robot is an intelligent machine that can work semi-autonomously or fully autonomously. Robots have basic characteristics such as perception, decision-making, and execution. They can assist or even replace humans in performing dangerous, heavy, and complex tasks, improve work efficiency and quality, serve human life, and expand or extend the scope of human activities and capabilities. A patrol robot is a type of robot. A patrol robot can either be commanded by a human, run a pre-programmed program, or act according to principles formulated based on artificial intelligence technology. Its task is to assist or replace human work.

[0003] Currently, when existing patrol robots are on patrol, they cannot be lifted, it is inconvenient to adjust the height of the pan-tilt, and they are easily blocked by external obstacles, resulting in blocked shooting images, with relatively large limitations and affecting the overall patrol effect. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A patrol robot with an anti-collision pan-tilt lifting function, comprising: A housing, wheels are installed at the bottom of the housing, and a rectangular opening is provided at the middle of the outer side of the housing; An adjustment mechanism for adjusting the height of the patrol shooting device, the adjustment mechanism is installed at the middle of the interior of the housing; Among them, the adjustment mechanism includes an electric telescopic rod, the electric telescopic rod is fixedly installed on the inner wall of the housing near the top through a bracket, a rotating boss is installed at the telescopic end of the electric telescopic rod, a circular ring is fixedly installed at the middle of the outer side of the rotating boss, a shooting unit is installed at the rotating end of the top of the rotating boss, a wedge-shaped block is fixedly installed at the side of the bottom of the circular ring, a connecting guide post is fixedly installed at the middle of the bottom of the rotating boss, and a jacking member is fixedly installed at the bottom end of the connecting guide post. By extending and contracting the telescopic end of the electric telescopic rod, the rotating boss can be driven to move up and down, so that the shooting unit moves along with the rotating boss, and thus the height of the shooting unit can be adjusted to achieve the lifting effect. When shooting and patrolling through the shooting unit, it is not easily blocked by obstacles, resulting in good shooting effects and improving the patrol safety guarantee; A protection component for safely protecting the patrol shooting device, the protection component is installed on the top of the housing; Among them, the protection component includes a protection cylinder. The bottom end of the protection cylinder is fixedly installed with the top end of the machine shell. At the edge of the bottom of the protection cylinder, a Z-shaped rod is fixedly installed. The Z-shaped rod is installed inside the machine shell. At the bottom end of the Z-shaped rod, a collar is fixedly installed. The connecting guide post passes through the center of the collar. At the bottom of the inner cavity of the protection cylinder and near the Z-shaped rod, a positioning tooth is fixedly installed. An auxiliary component is installed in the middle of the inner wall of the protection cylinder. When the telescopic end of the electric telescopic rod contracts, the rotating boss will be driven downward by the telescopic end of the electric telescopic rod, so that the shooting unit also moves downward together. When the shooting unit descends into the protection cylinder, the protection cylinder wraps around the periphery of the shooting unit, so as to protect the shooting unit and play a role in anti-collision.

[0005] Preferably, there are two electric telescopic rods, and the two electric telescopic rods are symmetrically installed along the connecting guide post. The two symmetric electric telescopic rods apply driving force to the rotating boss together, so that the rotating boss is evenly stressed. The connecting guide post is installed in the middle of the machine shell.

[0006] The telescopic end of the electric telescopic rod supports the rotating boss. By using the rotating end at the top of the rotating boss to rotate, the shooting unit can be driven to rotate. As the shooting unit rotates, the angle can be adjusted to increase the shooting range.

[0007] Preferably, the shooting unit is installed directly above the rotating boss. There are two wedge-shaped blocks, and the two wedge-shaped blocks are symmetrically installed along the central axis in the middle of the rotating boss.

[0008] Supported by the Z-shaped rod, the connecting guide post passes through the center of the collar. When the telescopic end of the electric telescopic rod drives the rotating boss to move, the connecting guide post slides inside the collar, so that the connecting guide post can be guided by the collar, making the connecting guide post drive the shooting unit to move smoothly. At the same time, with the support of the collar for the connecting guide post, the shooting unit is more stable during shooting and is not prone to shaking. The structures are linked together through the interaction between the structures.

[0009] Preferably, there are two positioning teeth, and the two positioning teeth are symmetrically installed along the Z-shaped rod. The positioning teeth are installed obliquely. The positioning teeth are installed directly below the wedge-shaped blocks. When the rotating boss moves downward, the ring will be driven downward, so that the wedge-shaped blocks move downward together. By embedding the wedge-shaped blocks between the two symmetric positioning teeth, the inclined surface of the positioning tooth coincides with the inclined surface at the bottom of the wedge-shaped block, so as to achieve clamping and positioning, making the shooting unit more stable inside the protection cylinder.

[0010] Preferably, the auxiliary component includes a connecting base, the end face outside the connecting base is fixedly installed with the annular surface of the inner wall of the protective cylinder, one end of the connecting base away from the inner wall of the protective cylinder is fixedly installed with a support rod, a sector-shaped elastic sheet is fixedly installed on the outer cylindrical surface of the support rod and on the side close to the central axis of the protective cylinder, and a protective pad is fixedly installed at the end of the sector-shaped elastic sheet away from the support rod. When the camera unit moves down into the protective cylinder, the arc surface outside the protective pad contacts the camera unit, so as to achieve flexible contact, which is not easy to scratch the surface of the camera unit and plays a protective role. Moreover, under the support of the support rod, the elastic force provided by the sector-shaped elastic sheet makes the camera unit receive elastic support, weakens the external collision force and provides buffer protection.

[0011] Preferably, there are two connecting bases, and the two connecting bases are symmetrically installed along the support rod. The support rods are evenly distributed on the annular surface of the inner wall of the protective cylinder.

[0012] Preferably, the sector-shaped elastic sheets are evenly distributed on the outer cylindrical surface of the support rod and on the side close to the central axis of the protective cylinder. The protective pad is arc-shaped, and the material of the protective pad is high-density sponge material.

[0013] Preferably, an anti-tipping component is installed on the outer side of the machine shell and close to the rectangular opening. The anti-tipping component includes a bent support leg. The outer side of the bent support leg and close to the top is rotatably installed with the outer side of the machine shell and close to the rectangular opening. The top of the bent support leg is fixedly installed with a force-bearing bent rod. The force-bearing bent rod is installed inside the machine shell. One end of the force-bearing bent rod away from the bent support leg is fixedly installed with a semi-sphere. The semi-sphere is installed at a position close to the top push member. A return elastic sheet is fixedly installed between the arc surface of the outer side of the force-bearing bent rod and the inner wall of the machine shell. A rolling sphere is rotatably installed at the bottom of the bent support leg. As the telescopic end of the electric telescopic rod pushes the rotating boss upward, the camera unit is lifted, making the overall center of gravity shift upward and become higher. And through the connecting guide column moving upward, it can drive the top push member to move upward. Through the circular ring at the end of the top push member contacting the semi-sphere, along with the continuous upward movement of the top push member, the semi-sphere receives an upward pushing force, so that the force-bearing bent rod receives an upward pushing force. And under the rotational connection of the bent support leg, the bent support leg and the force-bearing bent rod rotate together to adjust the angle. The return elastic sheet is compressed, and the rolling sphere moves toward the position close to the wheel. By using the bottom of the rolling sphere to contact the ground, the rolling support points for the machine shell can be increased, making the overall movement of the machine shell stable and not easy to tip over, and making full use of the interaction between the structures.

[0014] Preferably, the position of the bent support leg corresponds to the position of the rectangular opening. There are two bent support legs, and the two bent support legs are symmetrically installed along the central axis of the middle of the machine shell.

[0015] When the telescopic end of the electric telescopic rod contracts, the overall center of gravity of the device is lowered. As the connecting guide post drives the pushing member to move, the pushing force of the pushing member on the semi-sphere disappears. Under the elastic force of the reset elastic piece, the bending support leg and the force-bearing bending rod rotate in the reverse direction to reset, so that the bottom end of the bending support leg drives the rolling sphere to lift, and the wheel drives the whole casing to move conveniently.

[0016] Preferably, the semi-sphere is installed directly above the circular ring on the outer side of the pushing member, and the reset elastic piece is arc-shaped.

[0017] The present invention provides a patrol robot with an anti-collision pan-tilt lifting function, having the following beneficial effects: First, for the patrol robot with an anti-collision pan-tilt lifting function, by the elongation and contraction of the telescopic end of the electric telescopic rod, the rotating boss can be driven to move up and down, so that the shooting unit moves together with the rotating boss, and the height of the shooting unit can be adjusted to achieve the lifting effect. When patrolling by shooting with the shooting unit, it is not easily blocked by obstacles, so that the shooting effect is good and the patrol safety guarantee is improved.

[0018] Second, for the patrol robot with an anti-collision pan-tilt lifting function, the rotating boss is supported by the telescopic end of the electric telescopic rod, and the rotating end at the top of the rotating boss is used for rotation, so that the shooting unit can be driven to rotate. By adjusting the angle with the rotation of the shooting unit, the shooting range can be increased.

[0019] Third, for the patrol robot with an anti-collision pan-tilt lifting function, supported by the Z-shaped rod, the connecting guide post passes through the center of the collar. When the telescopic end of the electric telescopic rod drives the rotating boss to move, the connecting guide post slides inside the collar, so that the collar can guide the connecting guide post, making the connecting guide post drive the shooting unit to move smoothly. At the same time, with the support of the collar for the connecting guide post, the shooting unit is more stable during shooting and is not prone to shaking.

[0020] Fourth, for the patrol robot with an anti-collision pan-tilt lifting function, when the telescopic end of the electric telescopic rod contracts, the rotating boss will be driven by the telescopic end of the electric telescopic rod to move downward, so that the shooting unit also moves downward together. When the shooting unit descends into the protective cylinder, the protective cylinder wraps around the periphery of the shooting unit, so that the shooting unit can be protected and play an anti-collision role.

[0021] Fifth, for the patrol robot with an anti-collision pan-tilt lifting function, by the downward movement of the rotating boss, the circular ring can be driven to move downward, so that the wedge block moves downward together. By embedding the wedge block between two symmetric positioning teeth, the inclined surface of the positioning tooth coincides with the inclined surface at the bottom of the wedge block, and the clamping positioning can be realized.

[0022] VI. The patrol robot with anti-collision pan-tilt lifting function can make flexible contact by means of the arc surface outside the protective pad contacting the shooting unit, which is not easy to scratch the surface of the shooting unit and plays a protective role. Moreover, under the support of the support rod, the elastic force provided by the sector-shaped elastic piece enables the shooting unit to be elastically supported, weakens the external collision force, and conducts buffer protection.

[0023] VII. As the top moving part moves upward to apply a top driving force to the semi-sphere, the force-bearing bent rod is thus pushed upward. And under the rotational connection of the bent support leg, the bent support leg and the force-bearing bent rod rotate together to adjust the angle. The reset elastic piece is compressed, and the rolling sphere moves towards the position close to the wheel. By using the bottom of the rolling sphere to contact the ground, the rolling support points for the machine shell can be increased, making the overall movement of the machine shell stable and not prone to tipping.

[0024] VIII. As the connecting guide post drives the top moving part to move, the top driving force of the top moving part on the semi-sphere disappears. Under the elastic force of the reset elastic piece, the bent support leg and the force-bearing bent rod rotate in the reverse direction for resetting. As a result, the bottom end of the bent support leg drives the rolling sphere to lift, and the wheel drives the overall movement of the machine shell conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0028] The first embodiment is as Figures 1 - 4 shown. The present invention provides a technical solution: A patrol robot with an anti-collision pan-tilt lifting function, including: A housing 1, wheels 2 are installed at the bottom of the housing 1, and a rectangular opening 3 is provided in the middle of the outer side of the housing 1; An adjustment mechanism 4, which is used to adjust the height of the patrol shooting device, and the adjustment mechanism 4 is installed in the middle of the interior of the housing 1; Among them, the adjustment mechanism 4 includes an electric telescopic rod 41. The electric telescopic rod 41 is fixedly installed on the inner wall of the housing 1 near the top through a bracket. The telescopic end of the electric telescopic rod 41 is installed with a rotating boss 42. A ring 43 is fixedly installed in the middle of the outer side of the rotating boss 42. The rotating end of the top of the rotating boss 42 is installed with a camera unit 44. A wedge block 45 is fixedly installed at the side of the bottom of the ring 43. A connecting guide post 46 is fixedly installed in the middle of the bottom of the rotating boss 42. The bottom end of the connecting guide post 46 is fixedly installed with a pushing member 47. When the staff turns on the electric telescopic rod 41 to work, by using the extension and contraction of the telescopic end of the electric telescopic rod 41, the rotating boss 42 can be driven to move up and down, so that the camera unit 44 moves together with the rotating boss 42, and the height of the camera unit 44 can be adjusted to achieve the lifting effect. When shooting and patrolling through the camera unit 44, it is not easily blocked by obstacles; There are two electric telescopic rods 41, and the two electric telescopic rods 41 are symmetrically installed along the connecting guide post 46. The two relatively symmetric electric telescopic rods 41 are used together to apply a driving force to the rotating boss 42, so that the rotating boss 42 is evenly stressed. The connecting guide post 46 is installed in the middle of the machine shell 1.

[0029] The telescopic end of the electric telescopic rod 41 supports the rotating boss 42, and the rotating end at the top of the rotating boss 42 is used for rotation, so as to drive the shooting unit 44 to rotate. As the shooting unit 44 rotates, the angle can be adjusted, and the shooting range can be increased.

[0030] The shooting unit 44 is installed directly above the rotating boss 42. There are two wedge-shaped blocks 45, and the two wedge-shaped blocks 45 are symmetrically installed along the central axis in the middle of the rotating boss 42. Supported by the Z-shaped rod 52, the connecting guide post 46 passes through the center of the collar 53. When the telescopic end of the electric telescopic rod 41 drives the rotating boss 42 to move, the connecting guide post 46 slides inside the collar 53, so as to guide the connecting guide post 46 through the collar 53, making the connecting guide post 46 drive the shooting unit 44 to move smoothly. At the same time, the collar 53 supports the connecting guide post 46, making the shooting unit 44 more stable during shooting and not prone to shaking.

[0031] Second embodiment, as Figures 1 - 6 shown, on the basis of the first embodiment: The protection component 5, the protection component 5 is used for the safety protection of the patrol shooting device, and the protection component 5 is installed on the top of the machine shell 1; Among them, the protection component 5 includes a protection cylinder 51. The bottom end of the protection cylinder 51 is fixedly installed with the top end of the machine shell 1. The edge of the bottom of the protection cylinder 51 is fixedly installed with a Z-shaped rod 52. The Z-shaped rod 52 is installed inside the machine shell 1. The bottom end of the Z-shaped rod 52 is fixedly installed with a collar 53. The connecting guide post 46 passes through the center of the collar 53. A positioning tooth 54 is fixedly installed at the bottom of the inner cavity of the protection cylinder 51 and close to the Z-shaped rod 52. An auxiliary component 55 is installed in the middle of the inner wall of the protection cylinder 51. When the telescopic end of the electric telescopic rod 41 contracts, the rotating boss 42 will be driven by the telescopic end of the electric telescopic rod 41 to move downward, so that the shooting unit 44 also moves downward together. When the shooting unit 44 descends into the protection cylinder 51, the protection cylinder 51 wraps around the periphery of the shooting unit 44, so as to protect the shooting unit 44.

[0032] There are two positioning teeth 54, and the two positioning teeth 54 are symmetrically installed along the Z-shaped rod 52, and the positioning teeth 54 are installed obliquely. The positioning teeth 54 are installed directly below the wedge block 45. By moving the rotating boss 42 downward, the ring 43 will be driven to move downward, causing the wedge block 45 to move downward together. By embedding the wedge block 45 between the two symmetrical positioning teeth 54, the inclined surface of the positioning tooth 54 is made to coincide with the inclined surface at the bottom of the wedge block 45, and the clamping and positioning can be achieved, making the camera unit 44 more stable within the protective cylinder 51.

[0033] The auxiliary component 55 includes a connecting base 551, which is fixedly installed at the end face on the outer side of the connecting base 551 and the annular surface of the inner wall of the protective cylinder 51. One end of the connecting base 551 away from the inner wall of the protective cylinder 51 is fixedly installed with a support rod 552. On the outer circular surface of the support rod 552 and on the side close to the central axis of the protective cylinder 51, a sector-shaped elastic piece 553 is fixedly installed. One end of the sector-shaped elastic piece 553 away from the support rod 552 is fixedly installed with a protective pad 554. When the camera unit 44 moves downward into the protective cylinder 51, by using the arc-shaped surface on the outer side of the protective pad 554 to contact the camera unit 44, flexible contact can be achieved, which is not easy to scratch the surface of the camera unit 44 and has a protective effect. And under the support of the support rod 552, using the elastic force provided by the sector-shaped elastic piece 553, the camera unit 44 is elastically supported to weaken the external collision force and perform buffer protection.

[0034] There are two connecting bases 551, and the two connecting bases 551 are symmetrically installed along the support rod 552. The support rods 552 are evenly distributed on the annular surface of the inner wall of the protective cylinder 51.

[0035] The sector-shaped elastic pieces 553 are evenly distributed on the outer circular surface of the support rod 552 and on the side close to the central axis of the protective cylinder 51. The protective pad 554 is arc-shaped, and the material of the protective pad 554 is high-density sponge material.

[0036] The third embodiment is as Figures 1 - 8 shown, based on the first embodiment and the second embodiment: On the outer side of the casing 1 and near the rectangular opening 3, an anti-tipping component 6 is installed. The anti-tipping component 6 includes a bent support leg 61. The outer side of the bent support leg 61 and near the top is rotatably installed with the outer side of the casing 1 and near the rectangular opening 3. At the top of the bent support leg 61, a force-bearing bent rod 62 is fixedly installed. The force-bearing bent rod 62 is installed inside the casing 1. At the end of the force-bearing bent rod 62 away from the bent support leg 61, a semi-sphere 63 is fixedly installed. The semi-sphere 63 is installed near the top pushing member 47. Between the arc surface on the outer side of the force-bearing bent rod 62 and the inner wall of the casing 1, a reset elastic sheet 64 is fixedly installed. At the bottom end of the bent support leg 61, a rolling sphere 65 is rotatably installed. As the telescopic end of the electric telescopic rod 41 pushes the rotating boss 42 upward, the shooting unit 44 is lifted, causing the overall center of gravity to shift upward and become higher. And through the connecting guide post 46 moving upward, it can drive the top pushing member 47 to move upward. Through the circular ring at the end of the top pushing member 47 contacting the semi-sphere 63, along with the continuous upward movement of the top pushing member 47, the semi-sphere 63 receives an upward top force, so that the force-bearing bent rod 62 receives an upward pushing force. And under the rotational connection of the bent support leg 61, the bent support leg 61 and the force-bearing bent rod 62 rotate together to adjust the angle. The reset elastic sheet 64 is compressed, and the rolling sphere 65 moves toward the position close to the wheel 2. By using the bottom of the rolling sphere 65 to contact the ground, the rolling support points for the casing 1 can be increased, making the overall movement of the casing 1 stable and not prone to tipping.

[0037] The position of the bent support leg 61 corresponds to the position of the rectangular opening 3. There are two bent support legs 61, and the two bent support legs 61 are symmetrically installed along the central axis in the middle of the casing 1.

[0038] When the telescopic end of the electric telescopic rod 41 contracts, the overall center of gravity of the device is relatively low. As the connecting guide post 46 drives the top pushing member 47 to move, the top force of the top pushing member 47 on the semi-sphere 63 disappears. And under the elastic force of the reset elastic sheet 64, the bent support leg 61 and the force-bearing bent rod 62 rotate in the reverse direction for resetting. Thus, the bottom end of the bent support leg 61 drives the rolling sphere 65 to lift, and the wheel 2 drives the overall movement of the casing 1 conveniently.

[0039] The semi-sphere 63 is installed directly above the circular ring on the outer side of the top pushing member 47, and the reset elastic sheet 64 is arc-shaped.

[0040] During use, first, the staff turns on the electric telescopic rod 41 to work. By using the extension and contraction of the telescopic end of the electric telescopic rod 41, the rotating boss 42 can be driven to move upward and downward, so that the shooting unit 44 moves together with the rotating boss 42, and the height of the shooting unit 44 can be adjusted to achieve the lifting effect. When patrolling by shooting with the shooting unit 44, it is not easily blocked by obstacles; Moreover, supported by the Z-shaped rod 52, the connecting guide post 46 passes through the center of the collar 53. When the telescopic end of the electric telescopic rod 41 drives the rotating boss 42 to move, the connecting guide post 46 slides inside the collar 53, so that the collar 53 can guide the connecting guide post 46, making the connecting guide post 46 drive the shooting unit 44 to move smoothly. At the same time, with the support of the collar 53 for the connecting guide post 46, the shooting unit 44 is more stable during shooting and is not prone to shaking; The telescopic end of the electric telescopic rod 41 supports the rotating boss 42, and the rotating end at the top of the rotating boss 42 rotates, which can drive the shooting unit 44 to rotate. By adjusting the angle as the shooting unit 44 rotates, the shooting range can be increased; At the same time, as the telescopic end of the electric telescopic rod 41 pushes the rotating boss 42 upward, the shooting unit 44 is lifted, making the overall center of gravity shift upward and become higher. And as the connecting guide post 46 moves upward, it can drive the jacking member 47 to move upward. The circular ring at the end of the jacking member 47 contacts the semi-sphere 63. As the jacking member 47 continues to move upward, the semi-sphere 63 receives an upward jacking force, so that the force-bearing bending rod 62 receives an upward pushing force. Under the rotational connection of the bending support leg 61, the bending support leg 61 and the force-bearing bending rod 62 rotate together to adjust the angle. The reset elastic piece 64 is compressed, and the rolling sphere 65 moves toward the position close to the wheel 2. By using the bottom of the rolling sphere 65 to contact the ground, the rolling support points for the machine shell 1 can be increased, making the overall movement of the machine shell 1 smooth and not prone to tipping. At this time, the rolling of the wheel 2 can drive the overall movement of the machine shell 1 for patrol; And when the telescopic end of the electric telescopic rod 41 contracts, the rotating boss 42 will be driven downward by the telescopic end of the electric telescopic rod 41, making the shooting unit 44 also move downward together. When the shooting unit 44 descends into the protective cylinder 51, the protective cylinder 51 wraps around the periphery of the shooting unit 44, so that the shooting unit 44 can be protected; Moreover, as the rotating boss 42 moves downward, the circular ring 43 will be driven downward, making the wedge block 45 move downward together. By using the wedge block 45 to be embedded between two symmetric positioning teeth 54, the inclined surface of the positioning tooth 54 coincides with the inclined surface at the bottom of the wedge block 45, so that clamping and positioning can be achieved, making the shooting unit 44 more stable inside the protective cylinder 51; Furthermore, by using the arc surface on the outside of the protective pad 554 to contact the shooting unit 44, flexible contact can be carried out, which is not easy to scratch the surface of the shooting unit 44 and has a protective effect. And under the support of the support rod 552, with the elastic force provided by the sector-shaped elastic piece 553, the shooting unit 44 is elastically supported, weakening the external collision force and carrying out buffer protection; As the connecting guide post 46 drives the ejecting member 47 to move, the ejecting force of the ejecting member 47 on the semi-sphere 63 disappears, and under the elastic force of the reset elastic piece 64, the bending support leg 61 and the force-bearing bending rod 62 rotate in the reverse direction to reset, so that the bottom end of the bending support leg 61 drives the rolling sphere 65 to lift, and the wheel 2 drives the whole housing 1 to move conveniently.

[0041] Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
