Description

Technical Field

[0001] The present application relates to the field of pan-tilt cameras, and in particular to an anti-shake damping pan-tilt camera. Background Art

[0002] In modern camera applications, particularly in industrial monitoring and security surveillance, cameras often face complex vibration environments and heat dissipation challenges. For example, during the pitching operation of a gantry crane on a port, the camera must be mounted on the moving boom. The inertia generated by the crane's movement to the nearest point of its working position, or during rapid acceleration or deceleration during startup, can severely affect the stability of the captured image, resulting in blurred images and a lack of accurate operational information for operators. Vibration can even cause equipment failure.

[0003] Currently, some anti-shake pan-tilt cameras on the market mostly use electronic anti-shake or simple mechanical shock absorption structures, which have limited anti-shake effects and are difficult to adapt to severe vibration environments. Therefore, an anti-shake damping pan-tilt camera is proposed. Summary of the Invention

The flip baffle is provided with a second slide groove on the side away from the gravity ball. A slide rod corresponding to the second damping hole is fixed in the receiving groove. A damping diaphragm is fixed to one side of the flip baffle and the receiving groove, and a plurality of deformation holes arranged at equal distances are provided on the damping diaphragm.

[0006] Furthermore, the return spring has an elastic force that drives the gravity ball close to the support shaft, and the damping diaphragm has an elastic force that drives the flip baffle close to the support shaft. When the gravity ball overcomes the elastic force of the return spring and moves away from the support shaft to the maximum stroke, the flip baffle completely blocks the damping hole 1 under the combined action of flipping and translation. Furthermore, a corrugated arc plate is fixed between the buffer plate and the heat conduction plate, and an elastic node is provided at the connection between the buffer plate and the support shaft. The buffer plate and the two ends of the heat conduction plate are sealed by a sealing side membrane to form the buffer bin.

[0012] Compared with the existing technology, the advantages of this application are: By installing a damping mechanism within the damping tube and filling it with damping silicone oil, and utilizing variable damping oil holes to adjust the damping mechanism's operating resistance within the damping silicone oil, this invention effectively dissipates pan / tilt vibration energy and achieves superior anti-shake performance. Furthermore, the integration of the buffer compartment, buffer plate, and other structures further enhances anti-shake capabilities, ensuring that the camera maintains a vertical downward orientation during intense vibration operations, such as the pitching of the gantry crane's boom, producing stable, clear images. This provides operators with accurate operational information, improves efficiency, and ensures operational safety. The heat dissipation channels in the protective shell and the white light lamp housing are connected to the buffer chamber and the damping tube through the liquid inlet pipe and the liquid discharge pipe to form a heat dissipation circulation system. The movement of the damping mechanism can accelerate the circulation of the damping silicone oil in the system, taking away the heat generated by the camera device and the white light lamp, effectively reducing the internal temperature of the camera, ensuring the stable operation of the camera device and other equipment, and extending the service life of the equipment.

[0015] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of this application.

[0016] Example: The present invention provides an anti-shake damping pan-tilt camera, please refer to Figures 1-14 The anti-shake damping pan-tilt camera of the present invention consists of a camera 1 and a pan-tilt 3. The camera 1 includes a protective shell 11. A white light lamp 2 is fixed to one side of the protective shell 11. A camera device 13 is fixed inside the protective shell 11. The protective shell 11 and the shell of the white light lamp 2 are both provided with connected heat dissipation channels 14 for heat transfer and heat dissipation medium circulation.

[0017] Please refer to the Figure 1-Figure 3The pan-tilt platform 3 includes a top base 31 and a dynamic base 32. The top base 31 is fixed on the gantry boom of the overhead crane. A mounting top plate 12 is fixed on the top of the protective shell 11, and the mounting top plate 12 is fixedly connected to the bottom of the dynamic base 32, thereby realizing a stable connection between the camera 1 and the pan-tilt platform 3 and keeping the image acquisition end of the camera 1 always in a downward state, thereby realizing real-time monitoring of the boom working bucket. The camera device 13 of the camera 1 shoots in a stable working environment and transmits the captured image signal to the subsequent processing equipment. The white light lamp 2 works at night or in a dimly lit environment, and the light it emits illuminates the shooting area. Since the white light lamp 2 has an anti-black hole function, it can clearly present a color image, and the irradiation distance is not less than 100 meters, which meets the shooting requirements in complex scenes such as grabbing cargo, and ensures that the camera 1 can clearly capture the conditions of various parts in the cabin and on the deck, providing accurate working pictures for the operating personnel, and ensuring work safety and efficiency.

[0018] Please refer to the Figure 5 A damping tube 34 is provided on the top of the dynamic base 32, and end covers 33 are detachably connected to both ends of the damping tube 34. The top of the dynamic base 32 is fixedly connected to the end covers 33 on both sides, and a circulation mechanism 4 is provided at the bottom of the top base 31 for driving the circulation flow of the heat dissipation medium. Please refer to the Figure 10-13 The circulation mechanism 4 includes a support shaft 41 fixed to the bottom of the top base 31, and the end covers 33 are rotatably connected to the support shaft 41, so that the damping tube 34 can rotate relative to the support shaft 41. Two groups of symmetrically arranged damping mechanisms 5 are fixed to the inner wall of the damping tube 34. The damping tube 34 is also filled with damping silicone oil. In this application, the damping silicone oil also serves as a heat dissipation medium. A variable damping oil hole is provided on the damping mechanism 5 for adjusting the running resistance of the damping mechanism 5 in the damping silicone oil, thereby realizing the anti-shake function. Heat conducting plates 43 are symmetrically fixed on the upper and lower sides of the support shaft 41, and buffer plates 42 are symmetrically provided on both sides of the heat conducting plate 43. A buffer bin 45 with a variable volume is provided between the buffer plate 42 and the heat conducting plate 43. The buffer plate 42 is provided with a tapered hole 421 for intermittently connecting the damping tube 34 and the buffer bin 45. The input end of the heat dissipation channel 14 is connected to the buffer bin 45 through the liquid inlet pipe 141, and the output end of the heat dissipation channel 14 is connected to the damping tube 34 through the liquid discharge pipe 142. When the pan-tilt head 3 vibrates, the buffer bin 45 can interact with the damping silicone oil in the damping tube 34 through the tapered hole 421 to play a buffering and shock-absorbing role. At the same time, the damping silicone oil can circulate between the heat dissipation channel 14, the buffer bin 45 and the damping tube 34 to achieve a heat dissipation function. Please refer to the Figure 6-Figure 9The damping mechanism 5 includes a damping plate 51. One side of the damping plate 51 is provided with an arc-shaped cut edge 513 that contacts the outer wall of the support shaft 41, which can better adapt to the shape of the support shaft 41 and provide stable contact during rotation. The variable damping oil hole includes a damping hole 1 511 and a damping hole 2 512. A slide groove 1 514 is provided in the middle of the damping plate 51. A gravity ball 53 is slidably connected in the slide groove 1 514, and a return spring 54 is clamped between the gravity ball 53 and the slide groove 1 514. Please refer to the Figure 9 The two sides of the gravity ball 53 are symmetrically connected to the flip baffle 52 for rotation. A storage groove 501 matching the operating range of the flip baffle 52 is provided in the damping plate 51. A second slide groove 521 is provided on the side of the flip baffle 52 away from the gravity ball 53. A slide rod 515 corresponding to the second damping hole 512 is fixed in the storage groove 501. A damping diaphragm 522 is fixed to one side of the flip baffle 52 and the storage groove 501, and a plurality of equidistantly arranged deformation holes 523 are provided on the damping diaphragm 522. When the camera 1 has motion inertia following the displacement of the overhead crane, the gravity ball 53 uses inertia to move in the slide groove 1 514, driving the flip baffle 52 to move. The flip baffle 52 realizes the blocking or opening of the damping hole 1 511 and the damping hole 2 512 through the cooperation of the slide groove 2 521 and the slide rod 515 and the deformation of the damping diaphragm 522, thereby changing the running resistance of the damping mechanism 5 in the damping silicone oil and realizing a variable damping effect. Please refer to the Figure 11-13 A corrugated arc plate 44 is also fixed between the buffer plate 42 and the heat conducting plate 43. An elastic node 423 is provided at the connection between the buffer plate 42 and the support shaft 41. The buffer plate 42 and the two ends of the heat conducting plate 43 are sealed by the sealing side membrane 401 to form a buffer bin 45. The elastic node 423 and the corrugated arc plate 44 both have elastic force to drive the buffer plate 42 away from the heat conducting plate 43. When the gimbal 3 vibrates, the buffer plate 42 can be deformed under the action of the elastic node 423 and the corrugated arc plate 44, thereby changing the volume of the buffer bin 45 and further enhancing the buffering and shock absorption effect. Several conical holes 421 are equidistantly arranged on the buffer plate 42 . The diameter of the conical hole 421 on the side close to the heat conducting plate 43 is larger than that on the other side. A port cover film 422 is fixed in the conical hole 421 , and an elastic gap is provided between the port cover film 422 and the buffer plate 42 . Both ends of the support shaft 41 are provided with positioning pin holes 411, and the bottom of the top base 31 is provided with a shaft seat 311. The end of the support shaft 41 is fixed in the shaft seat 311 through the positioning pin holes 411 and pins to achieve a stable connection between the support shaft 41 and the top base 31. The end cover 33 is provided with a sealed bearing 331 that matches the support shaft 41 to ensure the stability and sealing of the connection and prevent leakage of the damping silicone oil. A discharge bin 412 and a reflux bin 413 are also provided in the support shaft 41. The buffer bin 45 is connected to the discharge bin 412 and a one-way membrane 1 4121 is provided at the connection node; the reflux bin 413 is connected to the damping tube 34 and a one-way membrane 2 4131 is provided at the connection node; the liquid inlet pipe 141 is connected to the discharge bin 412, and the one-way membrane 1 4121 has a unidirectional conductivity that prevents the damping silicone oil in the discharge bin 412 from flowing back into the buffer bin 45; the liquid discharge pipe 142 is connected to the reflux bin 413, and the one-way membrane 2 4131 has a unidirectional conductivity that prevents the damping silicone oil in the damping tube 34 from flowing back into the reflux bin 413; through this structural design, it is ensured that the damping silicone oil flows in a specific direction during the heat dissipation cycle, thereby improving the heat dissipation efficiency. The heat conducting plate 43 is a silicone heat conducting plate. The side of the heat conducting plate 43 away from the support shaft 41 is in contact with the inner wall of the damping tube 34, which can effectively conduct the heat generated by the damping silicone oil in the damping tube 34 due to the damping effect; the outer wall of the damping tube 34 is provided with heat dissipation fins to increase the heat dissipation area and accelerate heat dissipation.

[0019] Specifically, when the pan / tilt platform 3 and the camera 1 have inertia in following the speed change movement of the overhead crane, the gravity ball 53 on one side of the damping mechanism 5 is in the slide groove 1 514. Due to its own inertia, it will overcome the elastic force of the return spring 54 and move. The movement of the gravity ball 53 drives the flip baffle 52 to perform a composite action of flipping and translation. On the one hand, the damping diaphragm 522 is pulled and deformed by the flip baffle 52, and the deformation hole 523 is pulled and deformed, thereby increasing the resistance of the damping silicone oil to flow in the deformation hole 523. On the other hand, the flipping of the flip baffle 52 gradually reduces the effective flow of the damping hole 1 511 Area, in summary, the on-off state of the damping hole 1 511 and the damping hole 2 512 is changed, so as to adjust the running resistance of the damping mechanism 5 in the damping silicone oil. Specifically, when the speed change rate of the overhead crane is relatively low, the moving distance of the gravity ball 53 is small, so that the damping hole 1 511 and the damping hole 2 512 are partially opened, and the running resistance of the damping mechanism 5 is relatively small; when the speed change rate of the overhead crane is relatively high, the moving distance of the gravity ball 53 is large, the damping hole is blocked or the opening degree is changed, and the running resistance of the damping mechanism 5 is increased. The running resistance of the damping mechanism 5 in the damping silicone oil is utilized to effectively consume vibration energy and realize the anti-shake function.

[0020] At the same time, because the damping silicone oil is incompressible, the rotation of the damping plate 51 during the buffering process pushes the damping silicone oil, generating hydraulic pressure, toward the buffer plate 42 on one side. During this process, the hydraulic pressure generated by the damping silicone oil squeezes the port cover membrane 422, thereby compressing the elastic gap between the port cover membrane 422 and the buffer plate 42. At this point, the hydraulic pressure fully acts on the buffer plate 42. Through the deformation of the elastic node 423 and the corrugated arc plate 44, the volume of the buffer chamber 45 is changed, further damping vibration and enhancing the anti-shake effect. Throughout the anti-shake process, the two symmetrically arranged damping mechanisms 5 work together to suppress the vibration of the damping tube 34 from different directions. For example, when the pan / tilt head 3 is subjected to a leftward inertia, the gravity ball 53 in the left damping mechanism 5 moves first, quickly adjusting the state of the damping orifice and increasing the damping force on the left side. The right damping mechanism 5 also adjusts the damping force accordingly based on the transmission and changes of vibration, maintaining the stability of the damping tube 34, thereby ensuring that the camera 1 always maintains a vertical downward position and captures stable and clear images.

[0021] Please refer to the Figure 14 When the camera 1 is working, the camera device 13 and the white light lamp 2 generate heat, which is transferred to the heat dissipation channel 14 in the protective shell 11 and the white light lamp 2 shell. When there is no shaking, the principle of heat upward movement of the overall damping silicone oil is utilized to perform an automatic circulation heat dissipation effect. Since an elastic gap is provided between the port cover membrane 422 and the buffer plate 42, when there is no shaking, the port cover membrane 422 is not under pressure, so that the gap is open. The damping silicone oil in the buffer chamber 45 can intermittently interact with the damping silicone oil in the damping tube 34 through the tapered hole 421, and cooperate with the heat dissipation fins of the damping tube 34 to perform overall self-heating.

[0022] When shaking occurs to resist, the damping silicone oil is accelerated to circulate under the action of the circulation mechanism 4. The specific circulation path is that when the pressure in the buffer bin 45 changes due to the deformation of the buffer plate 42, the damping silicone oil in the buffer bin 45 that is preferentially dissipated by the heat conducting plate 43 enters the discharge bin 412 and flows into the bottom of the heat dissipation channel 14 through the liquid inlet pipe 141, and squeezes the damping silicone oil in the heat dissipation channel 14 to move upward. Since the heat conducting plate 43 is a silicone heat conducting plate, its side away from the support shaft 41 conflicts with the inner wall of the damping tube 34, which can effectively The heat of the damping silicone oil in the buffer bin 45 is quickly conducted out, so the temperature in the buffer bin 45 is lower than the temperature in the damping tube 34; the outer wall of the damping tube 34 is provided with heat dissipation fins, which increases the heat dissipation area and accelerates heat dissipation, thereby achieving efficient heat dissipation of the camera 1, ensuring that the camera device 13 and other equipment operate stably at an appropriate temperature, and at the same time, the one-way membrane 4121 prevents the damping silicone oil in the discharge bin 412 from flowing back to the buffer bin 45, ensuring that the damping silicone oil flows into the heat dissipation channel 14 through the discharge bin 412 and the liquid inlet pipe 141.

[0023] The thermal damping silicone oil in the heat dissipation channel 14 is pressurized and flows into the reflux chamber 413 through the drain pipe 142. Since the one-way membrane 2 4131 has unidirectional conductivity to prevent the damping silicone oil in the damping tube 34 from flowing back to the reflux chamber 413, the damping silicone oil can only flow from the reflux chamber 413 to the damping tube 34, thereby accelerating the circulation speed of the thermal damping silicone oil in the heat dissipation channel 14 and taking away the heat generated by the camera device 13 and the white light lamp 2.

[0024] By installing a damping mechanism 5 within the damping tube 34 and filling it with damping silicone oil, and utilizing a variable damping oil hole to adjust the operating resistance of the damping mechanism 5 within the damping silicone oil, the present invention effectively dissipates the vibration energy of the pan / tilt head 3 and achieves a superior anti-shake effect. Furthermore, the coordination of the buffer chamber 45, the buffer plate 42, and other structures further enhances the anti-shake capability, allowing the camera 1 to maintain a vertical downward position during intense vibration operations such as the pitching of the gantry crane boom, capturing stable and clear images. This provides operators with accurate operational information, improves operational efficiency, and ensures operational safety. The heat dissipation channel 14 in the protective shell 11 and the white light lamp 2 shell is connected to the buffer bin 45 and the damping tube 34 through the liquid inlet pipe 141 and the liquid discharge pipe 142 to form a heat dissipation circulation system, which can cooperate with the movement of the damping mechanism 5 to accelerate the circulation of damping silicone oil in the system, take away the heat generated by the camera device 13 and the white light lamp 2, effectively reduce the internal temperature of the camera 1, ensure the stable operation of the camera device 13 and other equipment, and extend the service life of the equipment.

[0025] The above is only the best implementation method adopted by this application in combination with current actual needs, but the scope of protection of this application is not limited to this.
