Description

Technical Field

[0001] This invention belongs to the field of camera vibration reduction technology, and specifically relates to a camera vibration reduction device, a camera vibration reduction system, and a camera. Background Technology

[0002] Existing camera mounts typically reduce camera vibration by adding soft shock-absorbing materials such as rubber pads to the camera mounting surface. However, this method can only reduce vibration in the direction perpendicular to the mounting surface, lacking the ability to reduce vibration in multiple directions and actually failing to completely isolate contact vibration (contact vibration refers to vibration generated when the camera is in direct contact with a vibration source). Furthermore, it is a passive vibration reduction method and cannot actively control the damping magnitude.

[0003] Therefore, existing technologies need to be improved and developed. Summary of the Invention

[0004] The purpose of this invention is to provide a camera vibration damping device, a camera vibration damping system, and a camera, which absorbs vibration energy from multiple directions through multiple electromagnetic vibration dampers, thereby effectively isolating contact vibration and achieving adjustable damping.

[0005] In a first aspect, the present invention provides a camera vibration reduction device, comprising a housing, wherein the housing contains:

[0006] A floating mount, the top surface of which passes through the housing and is used to mount a camera, and the floating mount is spaced apart from the housing around its perimeter;

[0007] Four first electromagnetic shock absorbers are provided, with their first ends fixedly connected to the bottom of the floating base and their second ends fixedly connected to the housing. The four first electromagnetic shock absorbers are respectively connected to the front, rear, left, and right sides of the floating base and are used to provide elastic force to the camera in the front-back and left-right directions.

[0008] The camera vibration reduction device provided by the present invention has electromagnetic dampers in four directions to absorb vibrations from multiple directions and separate the camera from the vibration source, thereby achieving the effect of isolating contact vibrations. The damping of the electromagnetic dampers can be adjusted by controlling the electrical signal.

[0009] Furthermore, two second electromagnetic shock absorbers are also provided inside the housing. The first end of the second electromagnetic shock absorber is fixedly connected to the bottom of the floating seat and the second end is fixedly connected to the housing. The two second electromagnetic shock absorbers are used to provide elastic force to the camera in the vertical direction.

[0010] The use of four primary electromagnetic dampers achieves a three-degree-of-freedom vibration reduction effect for the camera.

[0011] Furthermore, a third electromagnetic shock absorber is also provided inside the housing. The first end of the third electromagnetic shock absorber is fixedly connected to the bottom of the floating seat, and the second end is connected to a first universal joint. The first universal joint is fixedly connected to the housing. The third electromagnetic shock absorber is used to provide elastic force to the camera in the vertical direction.

[0012] This allows the camera to translate in six directions and oscillate in four directions, thereby achieving a five-degree-of-freedom vibration reduction effect.

[0013] Furthermore, the third electromagnetic damper is located between the two second electromagnetic dampers and is arranged side by side with the two second electromagnetic dampers.

[0014] Ensure that the damping performance of the second and third electromagnetic dampers is not affected by their structures obstructing each other.

[0015] Furthermore, both the first and second electromagnetic dampers dampen vibrations through repulsion, while the third electromagnetic damper dampens vibrations through attraction.

[0016] Furthermore, the first electromagnetic shock absorber, the second electromagnetic shock absorber, and the third electromagnetic shock absorber all include a connecting frame, a magnet, a shock-absorbing spring, an electromagnetic coil, and a magnetic core. The first end of the shock-absorbing spring is sleeved on the connecting frame, the magnet is mounted on the connecting frame and located inside the shock-absorbing spring, the magnetic core is inserted into the second end of the shock-absorbing spring, and the electromagnetic coil is sleeved on the magnetic core and located inside the shock-absorbing spring.

[0017] Furthermore, a distance sensor and a controller are also provided inside the housing. The controller is used to control the first electromagnetic damper, the second electromagnetic damper and the third electromagnetic damper according to the signal sent by the distance sensor.

[0018] Secondly, the present invention provides a camera vibration reduction system, including the above-mentioned camera vibration reduction device, fixing part and camera, wherein a first end of the fixing part is fixedly connected to the outside of the housing and a second end is fixedly connected to an external device; the camera is mounted on the top surface of the floating base.

[0019] Furthermore, the fixing part is a second universal joint.

[0020] Thirdly, the present invention provides a camera including the aforementioned camera vibration reduction device.

[0021] As can be seen from the above, the camera vibration reduction device of the present invention absorbs vibration energy from multiple directions by setting electromagnetic vibration dampers in four directions. Since the electromagnetic vibration dampers are located between the camera and the vibration source, the camera is prevented from directly contacting the vibration source, thereby effectively isolating contact vibration. At the same time, since the electromagnetic vibration dampers achieve the vibration reduction effect through electrical signal control, the damping of the electromagnetic vibration dampers can be actively adjusted by controlling the electrical signal, thereby achieving different degrees of vibration reduction effect, meeting various vibration reduction needs, and greatly improving its applicability.

The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0034] It should be noted that the terms "front-back direction," "left-right direction," and "up-down direction" used below are in conjunction with the appendix. Figure 2 The arrows marked in the text are for reference.

[0035] Reference Appendix Figure 1 Appendix Figure 2 and attached Figure 3 The present invention provides a camera vibration reduction device, comprising a housing 100, wherein the housing 100 contains:

[0036] A floating seat 200, the top surface of which passes through the housing 100 and is used to mount the camera 300, and the floating seat 200 is spaced apart from the housing 100 around its perimeter;

[0037] Four first electromagnetic shock absorbers 400 are provided. The first end of each first electromagnetic shock absorber 400 is fixedly connected to the bottom of the floating seat 200 and the second end is fixedly connected to the housing 100. The four first electromagnetic shock absorbers 400 are respectively connected to the front, rear, left and right sides of the floating seat 200 and are used to provide elastic force to the camera in the front-back and left-right directions.

[0038] In this embodiment, since there is a gap between the floating seat 200 and the housing 100 and the floating seat 200 is indirectly connected to the housing 100 through four first electromagnetic shock absorbers 400, unlike traditional soft shock-absorbing materials, the four first electromagnetic shock absorbers 400 can provide the camera 300 with translational capabilities in four directions: front, back, left, and right, thereby achieving a two-degree-of-freedom shock absorption effect. At the same time, the damping magnitude of the first electromagnetic shock absorbers 400 can be actively controlled by controlling the current intensity, thereby achieving different shock absorption effects. For example, when the camera is placed horizontally, the first electromagnetic shock absorber 400 facing the ground will be affected by gravity due to the gravity acting on the camera 300. Therefore, the damping of the first electromagnetic shock absorber 400 on that side can be appropriately increased to ensure that the shock absorption performance of the camera 300 is consistent in all directions.

[0039] In some embodiments, reference is made to the appendix. Figure 2 and attached Figure 3The housing 100 is also equipped with two second electromagnetic shock absorbers 500. The first end of the second electromagnetic shock absorber 500 is fixedly connected to the bottom of the floating seat 200 and the second end is fixedly connected to the housing 100. The two second electromagnetic shock absorbers 500 are used to provide the camera with elastic force in the vertical direction.

[0040] In this embodiment, by setting two second electromagnetic dampers 500, the camera 300 is provided with translational capability in the vertical direction. In conjunction with the use of four first electromagnetic dampers 400, a three-degree-of-freedom damping effect is achieved for the camera.

[0041] In some embodiments, reference is made to the appendix. Figure 2 and attached Figure 3 The housing 100 is also equipped with a third electromagnetic shock absorber 600. The first end of the third electromagnetic shock absorber 600 is fixedly connected to the bottom of the floating seat 200 and the second end is connected to a first universal joint 610. The first universal joint 610 is fixedly connected to the housing 100. The third electromagnetic shock absorber 600 is used to provide the camera with elastic force in the vertical direction.

[0042] In practical applications, in addition to vibrations in the six directions mentioned above, the camera 300 may also experience oscillation vibrations. In this embodiment, a third electromagnetic damper 600 is provided and connected to the housing 100 through a first universal joint 610. On the one hand, the first universal joint 610 enables the camera 300 to achieve translation in six directions and oscillation in four directions. On the other hand, the third electromagnetic damper 600 can suppress the oscillation of the camera 300 through electromagnetic force, thereby achieving a five-degree-of-freedom damping effect.

[0043] In some embodiments, reference is made to the appendix. Figure 2 and attached Figure 3 The third electromagnetic damper 600 is located between the two second electromagnetic dampers 500 and is arranged side by side with the two second electromagnetic dampers 500.

[0044] The side-by-side arrangement ensures that the damping performance of the second electromagnetic damper 500 and the third electromagnetic damper 600 will not be affected by their structural obstruction. For example, when the two second electromagnetic dampers 500 and the third electromagnetic damper 600 are arranged in a triangle, the two second electromagnetic dampers 500 will obstruct the swing of the third electromagnetic damper 600, thereby weakening the swing damping effect of the third electromagnetic damper 600.

[0045] In some embodiments, the first electromagnetic damper 400 and the second electromagnetic damper 500 both dampen vibrations through repulsion, while the third electromagnetic damper 600 dampens vibrations through attraction.

[0046] In practical applications, since vibrations often propagate through the housing 100, in order for the electromagnetic shock absorber to achieve a damping effect, it is necessary to ensure that the housing 100 does not directly contact the floating seat 200 when vibration occurs. Therefore, in this embodiment, the first electromagnetic shock absorber 400 is configured as a repulsive damping device. As the housing 100 gradually approaches the floating seat 200, the repulsive force provided by the first electromagnetic shock absorber 400 gradually increases, making it difficult for the housing 100 to contact the floating seat 200, thereby avoiding direct contact between the housing 100 and the floating seat 200. The second electromagnetic shock absorber 500 works similarly and will not be described in detail here.

[0047] When the camera 300 experiences swaying vibration, the damping springs 730 in both the second electromagnetic damper 500 and the third electromagnetic damper 600 are in a bent state. Their recovery ability (even if the floating seat 200 / camera 300 resets) depends entirely on the material properties of the damping springs 730 themselves (since the second electromagnetic damper 500 only provides repulsive force, and repulsive force does not help the damping springs 730 recover). In order to suppress the swaying vibration as quickly as possible and ensure that the floating seat 200 / camera 300 is controllable, this embodiment sets the third electromagnetic damper 600 to provide attractive force to help the damping springs 730 recover, thereby actively controlling the position of the floating seat 200 / camera 300 and achieving the effect of quickly suppressing the swaying vibration.

[0048] In some embodiments, reference is made to the appendix. Figure 4 The first electromagnetic shock absorber 400, the second electromagnetic shock absorber 500 and the third electromagnetic shock absorber 600 each include a connecting frame 710, a magnet 720, a shock-absorbing spring 730, an electromagnetic coil 740 and a magnetic core 750. The first end of the shock-absorbing spring 730 is sleeved on the connecting frame 710. The magnet 720 is installed on the connecting frame 710 and located inside the shock-absorbing spring 730. The magnetic core 750 is inserted into the second end of the shock-absorbing spring 730. The electromagnetic coil 740 is sleeved on the magnetic core 750 and located inside the shock-absorbing spring 730.

[0049] In this embodiment, the electromagnetic damper (including the first electromagnetic damper 400, the second electromagnetic damper 500 and the third electromagnetic damper 600) has a simple structure and low cost. The damping spring 730 provides basic damping to help the camera 300 achieve vibration reduction. Combined with electromagnetic drive, it realizes active adjustment of damping, enabling the camera 300 to meet more vibration reduction needs and improving the overall universality.

[0050] In some embodiments, reference is made to the appendix. Figure 2The housing 100 is also equipped with a distance sensor 110 and a controller. The controller is used to control the first electromagnetic shock absorber 400, the second electromagnetic shock absorber 500 and the third electromagnetic shock absorber 600 according to the signal sent by the distance sensor 110. The distance sensor 110 can determine whether the floating seat 200 has shifted and send a signal to the electromagnetic shock absorber in time to realize the input feedback of the current intensity of the electromagnetic shock absorber, thereby actively controlling the current intensity of the electromagnetic shock absorber and achieving the effect of dynamic adjustment.

[0051] Reference Appendix Figure 1 The present invention also provides a camera vibration reduction system, including the camera vibration reduction device, the fixing part 800 and the camera 300 in the above embodiments. The first end of the fixing part 800 is fixedly connected to the outside of the housing 100 and the second end is fixedly connected to an external device; the camera 300 is mounted on the top surface of the floating seat 200.

[0052] In this embodiment, in practical applications, external vibrations are often transmitted to the camera 300 through the fixed part 800 via the housing 100. However, since the camera 300 is mounted on the floating seat 200 and the floating seat 200 itself is indirectly connected to the housing 100 through an electromagnetic shock absorber, the electromagnetic shock absorber isolates the floating seat 200 from the housing 100, avoiding direct contact between the two and effectively suppressing vibrations. This helps improve the stability of the camera 300 during actual operation, thereby ensuring the quality of the acquired images.

[0053] In some embodiments, reference is made to the appendix. Figure 1 The fixed part 800 is the second universal joint. The camera vibration damping device is fixedly connected to the external equipment through the second universal joint, which can increase the freedom of movement of the camera vibration damping device, thereby making it easier for the camera to obtain images from multiple directions.

[0054] The present invention also provides a camera, including the camera vibration reduction device described in the above embodiments.
