Description

Technical Field

[0001] This invention relates to the field of drone aerial photography, specifically to a camera control device and a drone. Background Technology

[0002] In some cases, shoulder-mounted and handheld photography are used primarily to give the footage a "breathing" quality. This refers to the slight, gentle shaking of the camera caused by the cameraman's breathing during filming. This slight, gentle shaking gives the footage a "breathing" quality. In video creation, footage with a "breathing" quality appears more realistic, thus bringing the viewer closer to the video and providing a stronger sense of immersion.

[0003] To give drone footage a "breathing" feel, patent application CN201710553921.4 discloses a drone with a rotating cam inside. The vibration caused by the rotation of the cam makes the drone footage shake periodically, thus giving the footage a "breathing" feel. The quality of the cam determines the amplitude of the shaking in the drone footage, which in turn affects the strength of the "breathing" feel. However, the quality of the cam in the above-mentioned drone is not adjustable, so the strength of the "breathing" feel it creates is fixed, which obviously cannot adapt to shooting scenarios where the intensity of the "breathing" feel changes.

[0004] Therefore, how to create different intensities of "breathing" in the shooting footage is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a camera control device and a drone to solve the technical problem of how to create different intensities of "breathing sensation" in the captured image in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a camera control device, comprising: Base; A plurality of cams are spaced apart and rotatably mounted on the base; A plurality of clutch components are spaced apart between a plurality of said cams, and the clutch components have a first state of transmitting a transmission between two adjacent cams, and a second state of disengaging from at least one of said cams; and A drive element that connects to and drives at least one of the cams.

[0007] In some embodiments, the cam includes an axially extending shaft, the clutch includes a slider, a drive roller, and an adjustment unit. The drive roller is rotatably mounted on the slider in a direction parallel to the shaft. The slider is slidably disposed on the base, and its sliding trajectory has a first position where the drive roller presses against two adjacent shafts, and a second position where the drive roller disengages from at least one shaft. The adjustment unit is drively connected to the slider, and drives the slider to switch between the first position and the second position, so that the clutch switches between the first state and the second state.

[0008] In some embodiments, two adjacent rotating shafts are staggered, and when the slider is in the first position, the transmission roller is located between the two rotating shafts.

[0009] In some embodiments, the slider has a magnetic attraction portion, and the control portion includes an electromagnet mounted on the base and having a magnetic force that attracts the magnetic attraction portion to cause the slider to slide toward the first position.

[0010] In some embodiments, the control unit further includes a spring, with its two ends connected to the slider and the base, respectively, and the spring having an elastic force that causes the slider to slide toward the second position.

[0011] In some embodiments, a plurality of cams and a plurality of clutches are symmetrically arranged, and the states of the symmetrically arranged clutches are switched synchronously. The drive unit is connected to two cams located at both ends and drives the two cams located at both ends to rotate synchronously.

[0012] In some embodiments, the base has a plurality of storage cavities, and a plurality of the cams are embedded in the storage cavities one by one.

[0013] In some embodiments, the base has a plurality of connection holes on its outer periphery.

[0014] In some embodiments, both the rotating shaft and the transmission roller are covered with rubber pads on their outer peripheries.

[0015] Secondly, the present invention also provides a drone equipped with the aforementioned camera control device.

[0016] Compared with the prior art, the camera control device provided by the present invention has the following advantages: First, the base is mounted on the drone, and each cam is rotatably mounted on the base. A drive mechanism rotates the cams, and the periodic rotation of the cams causes a gentle shaking effect in the footage captured by the drone, creating a "breathing" feel in the shot. The working state of each clutch can be controlled, thereby changing the number of rotating cams. More rotating cams result in a greater amplitude of shaking in the shot, while fewer rotating cams result in a smaller amplitude of shaking, making the shaking amplitude controllable and allowing for different intensities of "breathing" effect in the captured footage.

Detailed Implementation

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] To address the technical problem of creating different intensities of "breathing" in drone footage, this invention provides a camera control device that can change the number of rotating cams 200 to alter the vibration amplitude of the image, thereby creating different intensities of "breathing" in the captured footage.

[0020] It should be noted that the camera control device of the present invention is used for, but not limited to, drone aerial photography. For ease of explanation, this invention will only use the application of the camera control device to drone aerial photography as an example. The principle of the camera control device in other types of equipment is essentially the same as that in drone aerial photography, and will not be described in detail here.

[0021] Please see Figure 1 , Figure 1The present invention is a schematic diagram of the structure of a camera control device in one embodiment of the present invention. The camera control device includes a base 100, a plurality of cams 200 and a plurality of clutches 300. The plurality of cams 200 are spaced apart and rotatably mounted on the base 100. The plurality of clutches 300 are spaced apart between the plurality of cams 200. The clutches 300 have a first state of transmitting and connecting two adjacent cams 200, and a second state of disengaging from at least one cam 200. The drive member 400 is connected to and drives at least one cam 200.

[0022] In this embodiment, the base 100 is first mounted on the drone, and each cam 200 is rotatably mounted on the base 100. The drive component 400 drives the cams 200 to rotate. The periodic rotation of the cams 200 causes a gentle shaking in the image captured by the drone, thus creating a "breathing" effect in the captured image. The working state of each clutch 300 can be controlled, thereby changing the number of rotating cams 200. The more rotating cams 200, the greater the shaking amplitude of the captured image; the fewer rotating cams 200, the smaller the shaking amplitude of the captured image. This makes the shaking amplitude of the captured image controllable, allowing the captured image to create different intensities of "breathing" effect.

[0023] In some embodiments, the cam 200 includes an axially extending shaft 210, and the clutch 300 includes a slider 310, a drive roller 320, and an adjustment unit 330. The drive roller 320 is rotatably mounted on the slider 310 in a direction parallel to the shaft 210. The slider 310 is slidably disposed on the base 100, and its sliding trajectory has a first position in which the drive roller 320 presses against two adjacent shafts 210, and a second position in which the drive roller 320 disengages from at least one shaft 210. The adjustment unit 330 is drively connected to the slider 310, which drives the slider 310 to switch between the first position and the second position, so that the clutch 300 switches between the first state and the second state. When the slider 310 is in the first position, the transmission roller 320 presses against two adjacent rotating shafts 210. The friction between the transmission roller 320 and the rotating shaft 210 causes the rotating shaft 210 to drive the transmission roller 320 to rotate. The rotating transmission roller 320 then drives the other rotating shaft 210 to rotate, establishing a transmission relationship between the two adjacent rotating shafts 210, thereby causing the two adjacent cams 200 to rotate synchronously. Once the slider 310 moves to the second position, the transmission roller 320 disengages from either rotating shaft 210, and the transmission relationship between the two adjacent rotating shafts 210 is lost.

[0024] In some embodiments, adjacent rotating shafts 210 are staggered, and when the slider 310 is in the first position, the transmission roller 320 is located between the two rotating shafts 210. Because the adjacent rotating shafts 210 are staggered, there is partial overlap between the rotating shafts 210 in the length direction, thereby improving space utilization.

[0025] Any implementation of the control unit 330 that allows the slider 310 to repeatedly switch between the first and second positions is feasible. In some embodiments, the slider 310 has a magnetic attraction part 311, and the control unit 330 includes an electromagnet 331. The electromagnet 331 is mounted on the base 100 and has a magnetic force that attracts the magnetic attraction part 311, causing the slider 310 to slide towards the first position. In actual use, once the electromagnet 331 is powered, giving it a magnetic force, the magnetic force attracts the magnetic attraction part 311, causing the slider 310 to switch towards the first position, thereby causing the transmission roller 320 to press against the two adjacent rotating shafts 210.

[0026] Based on the above embodiments, in some embodiments, the control unit 330 further includes a spring 332, with its two ends connected to the slider 310 and the base 100, respectively. The spring 332 has a spring force that causes the slider 310 to slide towards the second position. Once the electromagnet 331 loses its magnetic force, the spring 332 will push the slider 310 to the second position, causing the transmission roller 320 to disengage from the rotating shaft 210. When the electromagnet 331 is energized, the magnetic force between the electromagnet 331 and the magnetic attraction part 311 will overcome the spring force of the spring 332, thereby causing the slider 310 to move towards the first position, and causing the transmission roller 320 to press against the rotating shaft 210.

[0027] It is understandable that the cams 200 in this application are driven sequentially, which means that there may be a situation where one cam 200 on one side is rotating while the other cam 200 remains stationary. This unbalanced arrangement will cause irregular vibrations, which is a way to create a special "breathing" effect in the image.

[0028] If it is necessary to improve the above-mentioned unbalanced arrangement and eliminate irregular screen jitter, the following examples can be referred to: Several cams 200 and several clutches 300 are symmetrically arranged, and the states of the symmetrically arranged clutches 300 switch synchronously. The drive unit 400 is connected to two cams 200 at both ends and drives the two cams 200 at both ends to rotate synchronously. In this way, the symmetrical clutches 300 switch and rotate synchronously, which in turn makes the symmetrical cams 200 rotate synchronously. This allows the camera control device to maintain balance and avoids irregular image shaking caused by internal force imbalance.

[0029] In some embodiments, the base 100 has a plurality of storage cavities 110, and a plurality of cams 200 are correspondingly embedded in the storage cavities 110.

[0030] In some embodiments, the base 100 has a plurality of connection holes 120 on its outer periphery to facilitate connection to the drone body using screws passing through the connection holes 120.

[0031] In some embodiments, both the rotating shaft 210 and the drive roller 320 are covered with rubber pads on their outer peripheries. The rubber pads can increase the friction between the rotating shaft 210 and the drive roller 320, preventing the drive roller 320 from slipping relative to the rotating shaft 210.

[0032] Secondly, there is a type of drone equipped with the aforementioned camera control device.

[0033] To better understand this invention, the following is combined with... Figures 1 to 3 The technical solution of the present invention will be described in detail below: First, the base 100 is mounted on the drone, and each cam 200 is rotatably mounted on the base 100. A drive unit 400 drives the cams 200 to rotate. The periodic rotation of the cams 200 causes a gentle shaking effect in the footage captured by the drone, creating a "breathing" effect in the captured image. When the slider 310 is in the first position, the transmission roller 320 presses against two adjacent rotating shafts 210. The friction between the transmission roller 320 and the rotating shafts 210 causes the rotating shafts 210 to drive the transmission roller 320 to rotate. The rotating transmission roller 320 then drives the other rotating shaft 210 to rotate, establishing a transmission relationship between the two adjacent rotating shafts 210, thus causing the two adjacent cams 200 to rotate synchronously. Once the slider 310 moves to the second position, the transmission roller 320 disengages from either rotating shaft 210, and the transmission relationship between the two adjacent rotating shafts 210 is lost. By adjusting the position of each slider 310, the number of rotating cams 200 can be adjusted. The more rotating cams 200 there are, the greater the shaking amplitude of the captured image; the fewer rotating cams 200 there are, the smaller the shaking amplitude of the captured image, making the shaking amplitude of the captured image controllable and creating different intensities of "breathing" in the captured image.
