Description

Technical Field

[0001] This application relates to the field of shock absorption and protection devices, and in particular to a shock absorption and protection device for a control ball used in police robot dogs. Background Technology

[0002] Police robot dogs are patrol devices integrating advanced technology and intelligent functions, and have been increasingly used in the field of public security in recent years. Police robot dogs generally walk on four legs and resemble real dogs in appearance. They are agile and capable of running, jumping, and autonomous obstacle avoidance.

[0003] The police robot dog is equipped with video acquisition devices such as a surveillance PTZ camera, which is a high-definition intelligent acquisition device, specifically a wireless, mobile, intelligent advanced surveillance camera. The police robot dog can perform real-time analysis of the scene seen by the surveillance PTZ camera using a multimodal large-scale model and provide timely warnings.

[0004] Currently, when police quadruped robot dogs are equipped with video acquisition devices such as surveillance cameras, the following methods are commonly used: ① Direct screw fixing without adding any shock absorption or protection devices, which cannot prevent the surveillance cameras and other equipment from being damaged by falling; ② External protective frames are designed, but no additional shock absorption devices are added, which cannot prevent the vibration and impact caused by the movement of the quadruped robot dog from damaging the video acquisition equipment; ③ Simple shock absorption devices are added to the bottom, such as ordinary steel wire rope shock absorbers, which cannot prevent the image from shaking violently. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this application is to provide a shock absorption and protection device for a surveillance ball used in police robot dogs, which can prevent the surveillance ball from being damaged by vibration and prevent the surveillance ball from capturing images that shake violently.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application provides a shock-absorbing and protective device for a surveillance ball used in a police robot dog. The device includes: a surveillance ball mounting plate, an upper support plate, a lower support plate, and at least two wire rope shock absorbers. The surveillance ball is fixedly mounted on the upper surface of the surveillance ball mounting plate. The upper support plate is fixedly mounted on the police robot dog, positioned above the surveillance ball mounting plate, and the upper support plate and the surveillance ball mounting plate are slidably connected vertically via several linear bearings. The lower support plate is fixedly mounted on the police robot dog, positioned below the surveillance ball mounting plate. At least two wire rope shock absorbers are circumferentially arranged around the vertical axis of the surveillance ball, with the upper end of each wire rope shock absorber connected to the lower surface of the surveillance ball mounting plate and the lower end connected to the upper surface of the lower support plate.

[0008] As a preferred technical solution, the upper support plate includes a first upper support plate and a second upper support plate, which are arranged opposite to each other on both sides of the control ball.

[0009] As a preferred technical solution, a vertical guide rod is fixedly provided on the control ball mounting plate. The vertical guide rod passes through the upper support plate, and a linear bearing is fixedly installed on the upper support plate. The linear bearing is fitted on the vertical guide rod and is slidably connected to the vertical guide rod.

[0010] As a preferred technical solution, two linear bearings are provided, one of which connects the first upper support plate and the control ball mounting plate, and the other linear bearing connects the second upper support plate and the control ball mounting plate.

[0011] As a preferred technical solution, the control ball includes a rotating gimbal, and the axis of the wire rope shock absorber is parallel to the tangential direction of the rotation of the rotating gimbal.

[0012] As a preferred technical solution, the vibration damping and protection device for the surveillance ball also includes: a protective bracket, which is fixedly installed on the police robot dog and at least partially surrounds the outer periphery of the surveillance ball; an upper support plate is fixedly installed on the protective bracket, and a lower support plate is fixedly installed on the protective bracket.

[0013] As a preferred technical solution, the lower support plate is rectangular.

[0014] As a preferred technical solution, the control ball shock absorption and protection device also includes a connecting bracket, which includes four connecting columns. The lower ends of the four connecting columns are fixedly installed on the four corners of the lower support plate, and the upper ends of the four connecting columns are fixedly connected to the upper support plate.

[0015] As a preferred technical solution, the protective bracket includes four inverted L-shaped support columns, which are fixedly installed on the upper surface of the upper support plate, and the tops of the four support columns are fixedly connected by connectors.

[0016] As a preferred technical solution, the protective support also includes two first crossbeams and two second crossbeams. The two first crossbeams are arranged opposite each other on the front and rear sides of the upper part of the protective support, and the two second crossbeams are arranged opposite each other on the left and right sides of the middle part of the protective support. The first crossbeams and the second crossbeams are used to fix and connect two adjacent support columns.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] ① This application uses at least two wire rope shock absorbers arranged circumferentially around the vertical axis of the control ball to transfer the control ball to the robot dog. This effectively absorbs and disperses the vibration generated by the robot dog during movement, thereby protecting the control ball from vibration damage and extending its service life.

[0019] ② The upper support plate and the control ball mounting plate are connected by several linear bearings that slide up and down. The linear bearings effectively limit the left and right sway of the control ball, ensuring the stability of the video image collected by the control ball and ensuring the capabilities of face recognition, license plate recognition, etc. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, this application provides a control ball shock absorption and protection device 101 used in police robot dogs. The control ball shock absorption and protection device 101 includes: a control ball mounting plate 17, an upper support plate 11, a lower support plate 12, and at least two wire rope shock absorbers 13.

[0028] The surveillance camera 201 is fixedly mounted on the upper surface of the surveillance camera mounting plate 17. The surveillance camera 201 is a high-definition intelligent acquisition device, specifically a wireless, mobile, intelligent advanced surveillance camera. The police robot dog can perform real-time analysis of the scene seen by the surveillance camera 201 using a multimodal large-scale model and provide timely warnings. It should be noted that the surveillance camera 201 can also be a dual-light pan-tilt unit; a single or dual-light bullet camera; a PTZ camera; a panoramic camera, or other video acquisition devices.

[0029] The upper support plate 11 is fixedly installed on the police robot dog, and is mounted above the control ball mounting plate 17. The upper support plate 11 and the control ball mounting plate 17 are slidably connected vertically by several linear bearings 15. The lower support plate 12 is fixedly installed on the police robot dog, and is mounted below the control ball mounting plate 17. At least two wire rope shock absorbers 13 are arranged circumferentially around the vertical axis of the control ball 201. The upper end of the wire rope shock absorber 13 is connected to the lower surface of the control ball mounting plate 17, and the lower end of the wire rope shock absorber 13 is connected to the upper surface of the lower support plate 12.

[0030] It should be noted that the number of wire rope vibration isolators 13 can be increased or decreased, or the type of wire rope vibration isolators 13 can be changed to metal rubber vibration isolators, steel spring vibration isolators, rubber vibration isolators, air cushion vibration isolators, etc., to adapt to different video acquisition equipment and different actual load conditions, depending on the actual load conditions.

[0031] In this application, four wire rope shock absorbers 13 are provided, and the four wire rope shock absorbers 13 are evenly arranged around the circumference of the control ball mounting plate 17.

[0032] With the above settings, this application has the following beneficial effects:

[0033] ① This application uses at least two wire rope shock absorbers 13 arranged circumferentially around the vertical axis of the control ball 201. The control ball 201 is transferred and installed on the robot dog through the wire rope shock absorbers 13. This can effectively absorb and disperse the vibration generated by the robot dog during movement, thereby protecting the control ball 201 from vibration damage and extending the service life of the control ball 201.

[0034] It should be noted that when the robot dog stands on a reference plane, the direction parallel to the reference plane is defined as horizontal, and the direction perpendicular to the reference plane is defined as vertical.

[0035] The vibrations generated by the robot dog during its movement include lateral vibration and vertical vibration. When the control ball 201 is subjected to lateral vibration, the compression or tension of the wire rope damper 13 along its length will achieve the effect of lateral vibration damping. When the control ball 201 is subjected to vertical vibration, a vertical relative displacement occurs between the control ball 201 and the robot dog, and the compression or tension of the wire rope damper 13 along its radial direction will achieve the effect of vertical vibration damping.

[0036] ② The upper support plate 11 and the control ball mounting plate 17 are connected by several linear bearings 15 sliding up and down. The linear bearings 15 effectively limit the left and right swaying of the control ball 201, ensuring the stability of the video image collected by the control ball 201 and ensuring the capabilities of face recognition, license plate recognition, etc.

[0037] Due to the limitations of its mounting structure, the control ball mounting plate 17 can only move vertically relative to the upper support plate 11 via the linear bearing 15. Therefore, the displacement of the control ball 201 and the control ball mounting plate 17 caused by vibration only occurs vertically. Furthermore, the lower surface of the control ball mounting plate 17 is connected to the lower support plate 12 via a wire rope shock absorber 13. Due to the limitation of the wire rope shock absorber 13, the vertical displacement amplitude of the control ball 201 and the control ball mounting plate 17 is relatively small. Therefore, this application effectively limits the left-right swaying of the control ball 201, ensuring the stability of the video images acquired by the control ball 201 and guaranteeing capabilities such as face recognition and license plate recognition.

[0038] As one implementation, the upper support plate 11 includes a first upper support plate 111 and a second upper support plate 112, which are arranged opposite to each other on both sides of the control ball 201. This design brings the following beneficial effects:

[0039] 1. The first upper support plate 111 and the second upper support plate 112 are arranged opposite to each other, providing support points on both sides for the control ball 201. This design helps to maintain the stability of the control ball 201 during the movement of the robot dog and reduces swaying or tilting caused by unilateral force.

[0040] 2. Dual-sided support can more effectively distribute the load borne by the control ball 201 and its mounting plate. This helps extend the service life of the shock absorption device while reducing the risk of damage caused by concentrated load.

[0041] 3. The dual-sided support design enhances the structural strength of the entire shock absorption and protection device. This helps ensure that the control ball 201 and its mounting plate remain intact and stable under extreme conditions such as strong impacts or vibrations.

[0042] 4. Through reasonable layout and design, the double-sided supporting upper plate 11 helps ensure that the surveillance camera 201 can capture a wider and clearer monitoring image. This helps improve the monitoring effect and provides the police with more accurate and timely on-site information.

[0043] As one implementation, a vertical guide rod 14 is fixedly mounted on the control ball mounting plate 17. The vertical guide rod 14 passes through the upper support plate 11, and a linear bearing 15 is fixedly mounted on the upper support plate 11. The linear bearing 15 is fitted onto the vertical guide rod 14 and is slidably connected to the vertical guide rod 14. This design brings the following beneficial effects:

[0044] 1. The sliding connection design between the linear bearing 15 and the vertical guide rod 14 ensures that the movement of the control ball 201 in the vertical direction is more stable, avoiding distortion or loss of monitoring images due to shaking or tilting.

[0045] 2. The sliding connection design of the linear bearing 15 makes the movement of the control ball 201 smoother and more fluid, avoiding interruption of the monitoring screen due to jamming or shaking.

[0046] Specifically, two linear bearings 15 are provided, one of which connects the first upper support plate 111 and the ball mounting plate 17, and the other linear bearing 15 connects the second upper support plate 112 and the ball mounting plate 17. This design brings the following beneficial effects:

[0047] 1. Two linear bearings 15 are respectively connected to two upper support plates 11, providing double-sided support and guidance for the control ball 201. This design helps maintain its stability when the robot dog moves or the control ball 201 adjusts its angle, reducing the possibility of swaying or tilting.

[0048] 2. The arrangement of double-sided linear bearings 15 can more effectively distribute the load borne by the control ball 201 and its mounting plate. This helps to avoid structural damage or performance degradation caused by excessive force on one side, while extending the service life of the entire shock absorption and protection device.

[0049] 3. Whether rising or falling, a smooth transition can be achieved through the synergistic action of the two linear bearings 15, avoiding interruption or distortion of the monitoring screen due to poor movement.

[0050] As one implementation, the control ball 201 includes a rotating gimbal 21, with the axis of the wire rope shock absorber 13 parallel to the tangential direction of the rotation of the rotating gimbal 21. This design brings the following beneficial effects:

[0051] 1. When the rotating gimbal 21 rotates, it will generate certain vibrations and impacts. Setting the axis of the wire rope shock absorber 13 to be parallel to the tangential direction of the rotation of the rotating gimbal 21 can more effectively absorb these vibrations and impacts, thereby protecting the control ball 201 and its internal components from damage.

[0052] 2. By optimizing shock absorption performance, this design helps ensure the stability of the 201 monitoring ball during rotation, reducing the possibility of shaking or tilting. This helps ensure the clarity and stability of the monitoring image, improving the monitoring effect.

[0053] 3. By reducing vibration and impact during rotation, this design helps extend the service life of the rotating gimbal 21. This helps reduce maintenance costs while improving the reliability and durability of the entire deployment ball 201 system.

[0054] 4. By optimizing shock absorption and improving the performance of the rotating pan-tilt unit 21, this design helps ensure that the surveillance sphere 201 can provide high-quality monitoring images in various complex environments. This helps provide the police with more accurate and timely on-site information, improving monitoring effectiveness.

[0055] As one implementation method, the surveillance ball shock absorption and protection device 101 further includes: a protective bracket 16, which is fixedly installed on the police robot dog and at least partially surrounds the outer periphery of the surveillance ball 201; an upper support plate 11 is fixedly installed on the protective bracket 16, and a lower support plate 12 is fixedly installed on the protective bracket 16. This design brings the following beneficial effects:

[0056] The protective bracket 16 and the wire rope shock-absorbing structure are organically combined, providing both protection and shock absorption functions. The control ball 201 is installed via a mounting plate. When the robot dog accidentally falls, the protective bracket 16 bears the force, but it will not be transmitted to the control ball 201, effectively protecting the control ball 201.

[0057] Specifically, the lower support plate 12 is rectangular in shape. This design brings the following benefits:

[0058] 1. The rectangular frame-shaped lower support plate 12 provides a larger support area, which can more effectively distribute the load borne by the control ball 201 and its mounting components. This design enhances the structural stability of the entire shock absorption and protection device, enabling it to withstand greater external impacts, thereby protecting the control ball 201 from damage.

[0059] 2. The rectangular frame structure has high rigidity and resistance to deformation. Under complex working conditions (such as strong vibration or impact), the lower support plate 12 can maintain the stability of its shape and size, ensuring the precise position of the control ball 201 and its mounting components.

[0060] More specifically, the ball bearing shock absorption and protection device 101 also includes a connecting bracket. The connecting bracket includes four connecting columns 161, the lower ends of which are fixedly installed on the four corners of the lower support plate 12, and the upper ends of which are fixedly connected to the upper support plate 11. This design brings the following beneficial effects:

[0061] 1. Four connecting columns 161 are fixed to the four corners of the lower support plate 12, forming a stable support frame. This design gives the entire connecting bracket higher rigidity and load-bearing capacity, effectively supporting the weight of the control ball 201 and its mounting components.

[0062] 2. By evenly distributing the columns at the four corners of the lower support plate 12, this design helps to distribute the load borne by the control ball 201. This helps to reduce the pressure on individual columns, thereby improving the stability and durability of the entire system.

[0063] 3. The four uprights, together with the upper support plate 11 and the lower support plate 12, constitute a complete shock absorption system. When the police robot dog moves or encounters bumpy road conditions, this system can work together to effectively absorb and disperse vibration energy.

[0064] 4. The support frame formed by the four columns allows maintenance personnel easier access to the 201 control ball and its mounting components. This helps to quickly complete tasks when repairs or component replacements are needed, reducing downtime.

[0065] More specifically, the protective bracket 16 includes four inverted L-shaped support columns 162, which are fixedly installed on the upper surface of the upper support plate 11. The tops of the four support columns 162 are fixedly connected by connectors 163. In this application, the connectors 163 are annular. This design brings the following significant advantages:

[0066] 1. Four inverted L-shaped support columns 162 form a stable support frame, providing strong support for the control ball 201. This design gives the entire protective support 16 high rigidity and load-bearing capacity, enabling it to withstand significant external impacts.

[0067] 2. The inverted L-shaped design of the columns allows for more effective distribution of the load borne by the control ball 201. By distributing the load across the four columns, the pressure on each individual column is reduced, thereby improving the stability and durability of the entire system.

[0068] 3. The inverted L-shaped column design makes it easier for maintenance personnel to access the 201 control ball and its mounting components. This helps to complete tasks quickly when repairs or component replacements are needed, reducing downtime.

[0069] More specifically, the protective bracket 16 also includes two first crossbeams 164 and two second crossbeams 165. The two first crossbeams 164 are arranged opposite each other on the front and rear sides of the upper part of the protective bracket 16, and the two second crossbeams 165 are arranged opposite each other on the left and right sides of the middle part of the protective bracket 16. Both the first crossbeams 164 and the second crossbeams 165 are used to fix and connect two adjacent bracket columns 162. This design brings the following significant benefits:

[0070] 1. By adding the first crossbeam 164 and the second crossbeam 165, the protective bracket 16 forms a more stable frame structure. This design enhances the rigidity and load-bearing capacity of the entire bracket, enabling it to more effectively support the weight of the control ball 201 and its mounting components.

[0071] 2. The addition of the crossbeam improves the torsional resistance of the protective bracket 16. Under complex working conditions (such as strong vibration or impact), the bracket can maintain the stability of its shape and size, preventing deformation or damage due to torsion.

[0072] 3. The design of the crossbeam ensures a more even distribution of vibration damping across the entire support structure. This helps improve damping efficiency and ensures that the 201 ball bearing system maintains stable operation under various working conditions.

[0073] 4. The addition of the crossbeam does not impede maintenance personnel's access to the control ball 201 and its mounting components. On the contrary, it provides a more stable platform, enabling maintenance personnel to perform repairs and component replacements more safely and conveniently.
