Description

Technical Field

[0001] This invention relates to the field of camera support equipment, and more specifically, to a vibration-damping and buffering support device for a four-axis pan-tilt camera circuit module. Background Technology

[0002] In the field of camera support equipment, sophisticated electronic circuit modules are integrated within the camera. These modules are the core of ensuring stable operation and high-quality imaging of the camera. During actual use, cameras inevitably suffer from various vibrations and impacts from the external environment. These complex and multidirectional forces are transmitted to the camera's internal components, severely affecting sensitive circuit modules. This can lead to issues such as faulty soldering or component detachment, or cause electronic signal malfunctions, ultimately resulting in shaky, blurry images or even equipment failure.

[0003] Existing devices achieve cushioning by placing simple elastic elements such as springs or rubber pads between the circuit module and the camera housing. However, this type of structure has significant limitations: its cushioning effect is often limited to a single or a limited number of directions (e.g., mainly for vertical impacts). For more complex combined vibrations and impacts from arbitrary angles in real-world applications, its cushioning effect is not ideal. When subjected to an oblique impact force, a single-direction cushioning mechanism cannot effectively decompose and absorb all the energy, potentially causing unnecessary deflection or continuous shaking of the circuit module, which in turn amplifies the negative impact on shooting stability.

[0004] To address this, a vibration-damping and buffering support device for the circuit module of a four-axis pan-tilt camera is proposed. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this invention is to provide a vibration-damping support device for a four-axis pan-tilt camera circuit module, aiming to solve the problem of single-direction buffering in the prior art and achieve effective buffering of impact forces in any direction.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A vibration-damping and buffering four-axis pan-tilt camera circuit module support device includes a bracket, the upper end of which is rotatably connected to a camera body. The camera body has an internal mounting groove, and a support component is provided inside the mounting groove. The support component is used to support the circuit module.

[0008] The support assembly includes a first air cylinder evenly installed on the four sides of the inner wall of the mounting groove. A first piston plate is slidably connected inside the first air cylinder. A first air hole is opened on one side of the first air cylinder. A first one-way valve is fixedly connected to the upper and lower positions inside the first piston plate. A connecting rod is fixedly connected to one side of the first piston plate. A circular shell is fixedly connected to one side of the connecting rod. A first spring is sleeved on the rod wall of the connecting rod. A circular block is slidably connected inside the circular shell. A second air cylinder is evenly fixedly connected to the outer side of the circular block. A second piston plate is slidably connected inside the second air cylinder. A second spring is fixedly connected to one side of the second piston plate. A second one-way valve is fixedly connected to the inside of the second piston plate. A support rod is fixedly connected to the other side of the second piston plate. The outer side of the support rod contacts the inner wall of the circular shell. A second air hole is opened on one side of the second air cylinder. A circular groove is opened on one side of the circular shell. A mounting plate is fixedly connected to one side of the circular block.

[0009] Preferably, the first air cylinder has a first circular hole on its side wall, and the second air cylinder has a second circular hole on its side wall.

[0010] Preferably, a first rotating ball is uniformly and movably connected inside the circular shell, and the first rotating ball is in contact with the circular block.

[0011] Preferably, a rod is fixedly connected to the rear end of the mounting plate, a support block is fixedly connected to the rear end of the rod, contact switches are uniformly fixedly connected to the outer side of the support block, a second rotating ball is movably connected inside the camera body, a support cylinder is fixedly connected to the front end of the second rotating ball, contact plates are provided at both the front and rear positions inside the support cylinder, a third rotating ball is rotatably connected to the front end of the support cylinder, the rod wall is slidably connected to the interior of the third rotating ball, and indicator lights are fixedly connected to both sides of the upper end of the camera body, the indicator lights are electrically connected to the contact switches.

[0012] Preferably, baffles are fixedly connected to the inner walls of the first air cylinders on both sides, and a third one-way valve is fixedly connected inside the baffles. An air guide pipe is fixedly connected to the lower end of the first air cylinder. Slide grooves are provided on both sides of the mounting plate. A moving strip is slidably connected inside the slide groove. A third spring is fixedly connected to one side of the moving strip. One end of the air guide pipe is connected to one side of the slide groove.

[0013] Preferably, a heat dissipation groove is provided at the lower end of the camera body.

[0014] Preferably, a circular opening is uniformly provided on one side of the circular shell.

[0015] Preferably, one end of the contact switch is provided with a deformation spring, and the deformation spring is fixedly connected to the support block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (1) When using the camera body, the circular block and the circular shell can absorb energy and buffer in any direction on the same level. With the addition of the first air cylinder and the connecting rod, the vibration of the mounting plate in any direction can be provided with energy absorption and buffering effect. Compared with the single buffering direction of the prior art, the buffering effect of this structure is more ideal and comprehensive. At the same time, through the setting of the first piston plate and the second piston plate, the device can slowly reset the first piston plate and the second piston plate through the action of air pressure each time buffering, avoiding the mounting plate from shaking back and forth, thereby improving a certain stability. In summary, when using this structure, it can effectively avoid the circuit module from being subjected to excessive shaking force, ensuring that the shooting effect will not be affected.

[0018] (2) When in use, when the indicator light is on, it indicates that the current shaking amplitude has exceeded the normal shooting range, or it may indicate that the support component is faulty.

[0019] (3) When shaking, the moving bar can increase the clamping force on the circuit module, making the circuit module and the mounting plate relatively stable. During normal operation, the pressure of the moving bar on the circuit module is small, avoiding damage to the circuit module due to excessive pressure over a long period of time, and further improving the performance.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 9 A shock-absorbing and buffered four-axis pan-tilt camera circuit module support device includes a bracket 1. The bracket 1 is existing technology and has multiple rotating shafts inside to ensure that the camera body 2 works horizontally. The upper end of the bracket 1 is rotatably connected to the camera body 2. The camera body 2 is used for shooting. The camera body 2 has an internal mounting groove and a support component inside the mounting groove. The support component is used to support the circuit module.

[0034] The support assembly includes a first air cylinder 6 evenly installed on the four sides of the inner wall of the mounting groove. A first piston plate 9 is slidably connected inside the first air cylinder 6 and can move inside the first air cylinder 6. A first air hole 8 is opened on one side of the first air cylinder 6. The first air hole 8 has a small diameter, so the exhaust speed is slow. A first one-way valve 10 is fixedly connected to both the upper and lower positions inside the first piston plate 9. The first one-way valve 10 is existing technology and can allow gas to pass in one direction. A connecting rod 15 is fixedly connected to one side of the first piston plate 9. The connecting rod 15 moves synchronously. A circular shell 7 is fixedly connected to one side of the connecting rod 15. The circular shell 7 moves synchronously with the connecting rod 15. The rod wall of the connecting rod 15 is slidably connected to the first air cylinder 6, thus making the connecting rod 15 relatively stable when moving. A first spring 12 is sleeved on the rod wall of the connecting rod 15. The first spring 12 provides a certain reaction force when the connecting rod 15 moves, and at the same time, it allows the connecting rod 15 to return to its original position when it is stationary. A circular block 14 is slidably connected inside the circular shell 7. The circular block 14 can move freely inside the circular shell 7. The circular shell 7 has evenly spaced circular openings 16 on one side for easy inspection of its internal structure. A second air cylinder 19 is evenly fixedly connected to the outer side of the circular block 14. The movement of the circular block 14 causes the fixedly connected second air cylinder 19 to move. A second piston plate 21 is slidably connected inside the second air cylinder 19, allowing it to move within the cylinder. A second spring 18 is fixedly connected to one side of the second piston plate 21. The second spring 18 generates a reaction force when the second piston plate 21 moves, and also provides a reaction force when the second piston plate 21 is stationary. This resets the second piston plate 21. A second one-way valve 22 is fixedly connected inside the second piston plate 21. A support rod 20 is fixedly connected to the other side of the second piston plate 21. The outer side of the support rod 20 contacts the inner wall of the circular shell 7 but is not connected to each other. A second air hole 24 is opened on one side of the second air cylinder 19. A circular groove 36 is opened on one side of the circular shell 7. The circular groove 36 is used to ensure that the position where the circular block 14 is connected to the mounting plate 3 has sufficient movement space when it moves. The mounting plate 3 is fixedly connected to one side of the circular block 14, and the circuit module is installed inside the mounting plate 3.

[0035] When using this device, if a strong external vibration occurs, the internal circuit module will generate a large relative force with the camera body 2 due to inertia. At this time, the mounting plate 3 will experience a shaking force. For the circular shell 7 and the circular block 14, the mounting plate 3 will cause the circular block 14 to move in any direction within the circular shell 7. This causes the circular block 14 to move the second air cylinder 19, which in turn moves the second piston plate 21 and the support rod 20. When the support rod 20 attempts to move, it is limited by the inner wall of the circular shell 7. At this time, the second air cylinder 19 moves relative to the support rod 20, and the support rod 20 causes the second piston plate 21 to move. The force of the second air cylinder 19 is buffered by the second spring 18. When plate 21 moves relative to the second air cylinder 19, the second one-way valve 22 is open, allowing some gas inside the second air cylinder 19 to escape. When the second spring 18 deforms and absorbs energy in preparation for release, the second one-way valve 22 is closed. When the second piston plate 21 moves to its reset position, the air pressure inside the second air cylinder 19 decreases, resulting in some resistance during the reset. At this time, gas slowly enters the second air cylinder 19 through the second air hole 24, causing the second piston plate 21 to slowly reset the support rod 20. For the first air cylinder 6, when the mounting plate 3 moves, the connecting rod 15 moves via the circular shell 7, and the moving connecting rod 15 drives the first piston. As plate 9 moves, the first piston plate 9 causes the first spring 12 to deform, thereby absorbing the kinetic energy of the mounting plate 3. The first air cylinders 6 are arranged in opposite directions, so when one first spring 12 is stretched, the opposite first spring 12 is compressed. When the first spring 12 is compressed, the first one-way valve 10 is open, allowing gas to enter the interior of the first air cylinder 6. After absorbing energy, the first piston plate 9 returns to its original position, and the first one-way valve 10 is closed. During this return, the air pressure inside the first air cylinder 6 increases, and the gas inside the first air cylinder 6 is slowly discharged through the first air hole 8. This causes the first piston plate 9 to slowly return the connecting rod 15 to its original position. It should be noted that the first spring 12 and the second spring 18 have relatively large elastic coefficients, so the internal mounting plate 3 will not shake during slight vibrations, avoiding minor shaking that could affect normal operation. Thus, when using the camera body 2, energy absorption and buffering can be achieved in any direction on the same level through the circular block 14 and the circular shell 7. Combined with the first air cylinder 6 and the connecting rod 15, this provides energy absorption and buffering for vibrations in any direction on the mounting plate 3. Compared to the single-direction buffering of existing technologies, this structure offers a more ideal and comprehensive buffering effect. Furthermore, the first piston plate 9 and the second piston plate 21, through the action of air pressure, allow the device to slowly reset each time it buffers.To prevent mounting plate 3 from wobbling back and forth, this design, after buffering, prevents it from shaking, thus improving stability. In summary, this structure effectively prevents excessive shaking of the circuit module during use, ensuring that the shooting effect is not affected.

[0036] like Figure 6 and Figure 7 As shown, the first cylinder 6 has a first circular hole 13 on its side wall, and the second cylinder 19 has a second circular hole 23 on its side wall. The first circular hole 13 and the second circular hole 23 ensure that one side of the first piston plate 9 and the second piston plate 21 will not be affected by air pressure when moving, and can normally perform air intake or exhaust. The other side of the first piston plate 9 and the second piston plate 21 is used to generate air pressure between the first cylinder 6 and the second cylinder 19.

[0037] like Figure 5 and Figure 7 As shown, a first rotating ball 17 is uniformly and movably connected inside the circular shell 7. The first rotating ball 17 contacts the circular block 14. By setting the first rotating ball 17, the friction between the circular block 14 and the inner wall of the circular shell 7 is reduced when the circular block 14 moves, making the circular block 14 move more smoothly.

[0038] like Figure 8 , Figure 9 and Figure 10 As shown, a rod 31 is fixedly connected to the rear end of the mounting plate 3. When the mounting plate 3 moves, it drives the rod 31 to move. A support block is fixedly connected to the rear end of the rod 31. Contact switches 33 are evenly fixedly connected to the outer side of the support block. When the contact switches 33 are subjected to external force, they will be energized. This is existing technology. A second rotating ball 28 is movably connected inside the camera body 2. A support cylinder 29 is fixedly connected to the front end of the second rotating ball 28. Contact plates 32 are provided at both the front and rear positions inside the support cylinder 29. A third rotating ball 30 is rotatably connected to the front end of the support cylinder 29. The rod wall of the rod 31 is slidably connected to the interior of the third rotating ball 30. The rod 31 can move relative to the third rotating ball 30. Under the action of the rod 31, when the front end of the support cylinder 29 moves, the third rotating ball 30 will move. Indicator lights 4 (LEDs) are fixedly connected to both sides of the upper end of the camera body 2. A current-limiting resistor R needs to be connected in series. Indicator 4 and contact switch 33 are electrically connected. One end of contact switch 33 is equipped with a deformation spring. When contact switch 33 contacts the inner wall, the deformation spring can deform and will not interfere with the movement of mounting plate 3, thus not affecting the shock absorption of mounting plate 3. The deformation spring is fixedly connected to the support block. It should be noted that the camera body 2 has an internal power supply to power indicator 4.

[0039] When the mounting plate 3 moves, it drives the fixedly connected rod 31 to move. When the rod 31 moves, it drives the third rotating ball 30 to move, and the front end of the support cylinder 29 will rotate accordingly. When the rod 31 moves relative to the support cylinder 29, it causes the contact switch 33 to be squeezed out from the inner wall of the support cylinder 29 or the contact plate 32, thereby subjecting the contact switch 33 to a certain external force and achieving the effect of energizing. The indicator light 4 is electrically connected to the contact switch 33, thereby causing the indicator light 4 to light up. When the indicator light 4 lights up, the shaking amplitude exceeds the preset range, which is not suitable for shooting. At the same time, if the indicator light 4 lights up in a stationary state, it indicates that the internal support component has malfunctioned and cannot perform the shock absorption function, which needs to be checked, further improving the applicability of the device.

[0040] like Figure 3 and Figure 4 As shown, baffles 34 are fixedly connected to the inner walls of the first air cylinders 6 on both sides. A third one-way valve 35 is fixedly connected inside the baffles 34. A gas guide pipe 11 is fixedly connected to the lower end of the first air cylinder 6. The gas guide pipe 11 is used for gas transmission. Slide grooves 25 are opened on both sides of the mounting plate 3. A moving strip 26 is slidably connected inside the slide groove 25. The moving strip 26 can move inside the slide groove 25. A third spring 27 is fixedly connected to one side of the moving strip 26. The third spring 27 and the moving strip 26 have a supporting effect, so that the moving strip 26 has a certain supporting effect on the circuit module. One end of the gas guide pipe 11 is connected to one side of the slide groove 25.

[0041] When the mounting plate 3 shakes, the shaking force on both sides causes the first piston plates 9 on both sides to move continuously left and right. The control direction of the third check valve 35 is opposite to that of the first check valve 10. When the first piston plate 9 approaches the baffle 34 When the first piston plate 9 moves away from the baffle 34, the first one-way valve 10 is closed and the third one-way valve 35 is open. When the first piston plate 9 moves away from the baffle 34, the first one-way valve 10 is open and the third one-way valve 35 is closed, which increases the air pressure at the location of the air guide pipe 11, and thus increases the air pressure inside the slide groove 25. Under the action of air pressure, the moving bar 26 is pushed, which increases the pressure of the moving bar 26 on the circuit module, thereby increasing the clamping force and making the circuit module and the mounting plate 3 in a stable state. When the gas inside the first air cylinder 6 is discharged, the pressure of the moving bar 26 on the circuit module decreases. It should be noted that the space on the side of the slide groove 25 located on the third spring 27 is small, so when the first piston plate 9 moves a certain distance, the air pressure inside the slide groove 25 increases. In this way, when shaking, the moving bar 26 can increase the clamping force on the circuit module, making the circuit module and the mounting plate 3 relatively stable. During normal operation, the pressure of the moving bar 26 on the circuit module is small, avoiding damage to the circuit module due to excessive pressure over a long period of time, and further improving the performance.

[0042] like Figure 2 As shown, a heat dissipation groove 5 is provided at the lower end of the camera body 2. The heat dissipation groove 5 is strip-shaped and is used to dissipate heat from the internal circuit modules to prevent the environment or its own temperature from being too high during operation, which would affect its normal operation and improve the shooting effect.

[0043] Working Principle: When using this device, a strong external vibration occurs, causing a large relative force between the internal circuit module and the camera body 2 due to inertia. This causes the mounting plate 3 to experience a shaking force. For the circular shell 7 and the circular block 14, the mounting plate 3 drives the circular block 14 to move in any direction within the circular shell 7. This causes the circular block 14 to move the second air cylinder 19, which in turn moves the second piston plate 21 and the support rod 20. When the support rod 20 attempts to move, it is limited by the inner wall of the circular shell 7. At this point, the second air cylinder 19 moves relative to the support rod 20, which in turn causes the second piston plate 21 to move. The second spring 18 provides cushioning for the movement of the second air cylinder. When the second piston plate 21 moves relative to the second cylinder 19, the second one-way valve 22 is open, allowing some gas inside the second cylinder 19 to be discharged. When the second spring 18 deforms and absorbs energy to prepare for release, the second one-way valve 22 is closed. When the second piston plate 21 moves to its reset position, the air pressure inside the second cylinder 19 decreases, resulting in some resistance when the second piston plate 21 resets. At this time, gas slowly enters the interior of the second cylinder 19 through the second air hole 24, causing the second piston plate 21 to drive the support rod 20 to slowly reset. For the first cylinder 6, when the mounting plate 3 moves, the connecting rod 15 moves via the set circular shell 7. The connecting rod 15 moves, causing the first piston plate 9 to move. The first piston plate 9 causes the first spring 12 to deform, thereby absorbing the kinetic energy of the mounting plate 3. The first air cylinder 6 is arranged in opposite directions, so when one first spring 12 is stretched, the opposite first spring 12 is compressed. When the first spring 12 is compressed, the first one-way valve 10 is open, allowing gas to enter the interior of the first air cylinder 6. After absorbing energy, the first piston plate 9 returns to its original position, and the first one-way valve 10 is closed. When the first piston plate 9 returns to its original position, the air pressure inside the first air cylinder 6 increases. The gas inside the first air cylinder 6 is slowly discharged through the first air hole 8, thereby allowing the first piston plate 6 to move. The stopper plate 9 drives the connecting rod 15 to slowly return to its original position. It should be noted that the first spring 12 and the second spring 18 have relatively high elastic coefficients, so even slight vibrations will not cause the internal mounting plate 3 to shake, preventing minor wobbling from affecting normal operation. Thus, when using the camera body 2, energy absorption and buffering can be achieved in any direction on the same level through the circular block 14 and the circular shell 7. Combined with the first air cylinder 6 and the connecting rod 15, this provides energy absorption and buffering for vibrations in any direction of the mounting plate 3. Compared to the single-direction buffering of existing technologies, this structure offers a more ideal and comprehensive buffering effect. Furthermore, the first piston plate 9 and the second piston plate 21, through the action of air pressure, ensure that the device effectively absorbs and buffers vibrations during each buffering operation.This allows the first piston plate 9 and the second piston plate 21 to slowly return to their original positions, preventing the mounting plate 3 from wobbling back and forth. After buffering, the mounting plate 3 will not wobble, thus improving stability. In summary, this structure effectively prevents the circuit module from being subjected to excessive shaking during use, ensuring that the shooting effect is not affected.

[0044] Furthermore, when the mounting plate 3 moves, it drives the fixedly connected rod 31 to move. When the rod 31 moves, it drives the third rotating ball 30 to move, and the front end of the support cylinder 29 will rotate accordingly. When the rod 31 moves relative to the support cylinder 29, it causes the contact switch 33 to be squeezed out from the inner wall of the support cylinder 29 or the contact plate 32, thereby causing the contact switch 33 to be subjected to a certain external force, thus achieving the effect of energizing. The indicator light 4 is electrically connected to the contact switch 33, thereby causing the indicator light 4 to light up. When the indicator light 4 lights up, the shaking amplitude exceeds the preset range, which is not suitable for shooting. At the same time, if the indicator light 4 lights up in a stationary state, it indicates that the internal support component has malfunctioned and cannot perform the shock absorption function, which needs to be checked, further improving the applicability of the device.

[0045] Furthermore, when the mounting plate 3 shakes, the shaking force on both sides causes the first piston plates 9 on both sides to move continuously left and right. The control direction of the third check valve 35 is opposite to that of the first check valve 10. When the first piston plate 9 approaches the baffle 34... When the first piston plate 9 moves away from the baffle 34, the first one-way valve 10 is closed and the third one-way valve 35 is open. When the first piston plate 9 moves away from the baffle 34, the first one-way valve 10 is open and the third one-way valve 35 is closed, which increases the air pressure at the location of the air guide pipe 11, and thus increases the air pressure inside the slide groove 25. Under the action of air pressure, the moving bar 26 is pushed, which increases the pressure of the moving bar 26 on the circuit module, thereby increasing the clamping force and making the circuit module and the mounting plate 3 in a stable state. When the gas inside the first air cylinder 6 is discharged, the pressure of the moving bar 26 on the circuit module decreases. It should be noted that the space on the side of the slide groove 25 located on the third spring 27 is small, so when the first piston plate 9 moves a certain distance, the air pressure inside the slide groove 25 increases. In this way, when shaking, the moving bar 26 can increase the clamping force on the circuit module, making the circuit module and the mounting plate 3 relatively stable. During normal operation, the pressure of the moving bar 26 on the circuit module is small, avoiding damage to the circuit module due to excessive pressure over a long period of time, and further improving the performance.
