Description

Technical Field

[0001] The utility model belongs to the technical field of pan-tilt, and particularly relates to an anti-shake pan-tilt and a camera device with the same. Background Art

[0002] In the field of miniature three-axis anti-shake pan-tilt motors, the internal anti-shake structure design plays a decisive role in performance, yield, and reliability. Conventional ball drive type has high requirements for ball anti-shake drive design, with a complex structure and difficult assembly. Therefore, it is not easy to meet the performance test requirements, and repeated assembly is required multiple times to improve the yield and reliability. Summary of the Utility Model

[0003] To solve the above technical problems, the utility model discloses an anti-shake pan-tilt, which can realize the reliable connection of the anti-shake structure, simplify the assembly on the basis of a compact structure, and thereby improve the yield and reliability of the product. The utility model also discloses a camera device with the above anti-shake pan-tilt.

[0004] An anti-shake pan-tilt, comprising:

[0005] A first fixing bracket and a second fixing bracket;

[0006] A rotating member provided with a first driving member; and

[0007] A bracket provided with a second driving member, and the bracket is arranged between the first fixing bracket and the second fixing bracket;

[0008] Wherein, the rotating member is provided with a first rolling surface and a second rolling surface, a first ball is arranged between the first rolling surface and the first fixing bracket, and a second ball is arranged between the second rolling surface and the second fixing bracket;

[0009] The first rolling surface and the second rolling surface have an arc along the circumferential direction of the pan-tilt, or the contact surfaces between the first fixing bracket and the first ball, and between the second fixing bracket and the second ball have an arc along the circumferential direction of the pan-tilt;

[0010] The first driving member and the second driving member are electromagnetically matched to drive the rotation of the rotating member.

[0011] When electromagnetic induction is generated between the first driving member and the second driving member, the rotating member can rotate relative to the first fixing bracket and the second fixing bracket. By adjusting the relative angle of the rotating member, the vibration interference generated during shooting can be effectively counteracted, thereby eliminating the blurring phenomenon in the image, improving the clarity and overall quality of the image or video, and making the finished film more stable and smooth; the first ball and the second ball can improve the rotation stability of the rotating member, making the rotation of the rotating member more smooth.

[0012] Preferably, the first fixing bracket is provided with a first limiting portion, the second fixing bracket is provided with a second limiting portion, and the rotating member is located between the first limiting portion and the second limiting portion to axially limit the rotating member along the pan-tilt by the first limiting portion and the second limiting portion.

[0013] The first limiting portion and the second limiting portion can limit the rotating member between the first fixing bracket and the second fixing bracket, making the movement of the rotating member more stable and improving the use reliability.

[0014] Preferably, the inner top surface of the first fixing bracket is configured as the first limiting portion, the second fixing bracket is provided with a leg, and the free end of the leg is configured as the second limiting portion.

[0015] This structure is simple and easy to implement, and makes the pan-tilt have good structural compactness.

[0016] Preferably, the arc diameter formed by the movement paths of the first ball and the second ball along the circumferential direction of the pan-tilt is smaller than the maximum diameter of the rotating member.

[0017] Since the arc diameter formed by the movement paths of the first ball and the second ball along the circumferential direction of the pan-tilt is smaller than the maximum diameter of the rotating member, and the first ball cooperates with the first fixing bracket and the second ball cooperates with the second fixing bracket, actually the first fixing bracket and the second fixing bracket cover the rotating member. Therefore, on the basis that the first fixing bracket and the second fixing bracket are respectively connected to both ends of the bracket, the overall structure is more compact, and this structure makes the assembly process more organized and avoids complex assembly processes.

[0018] Preferably, the first fixing bracket is provided with a first connecting arm, and a first mounting portion for mounting the first ball is provided on the end surface of the first connecting arm close to the inner side of the pan-tilt;

[0019] The second fixing bracket is provided with a second connecting arm, and a second mounting portion for mounting the second ball is provided on the end surface of the second connecting arm close to the inner side of the pan-tilt;

[0020] The first connecting arm and the second connecting arm are arranged in a staggered manner in the circumferential direction of the pan-tilt.

[0021] This structure is simple, optimizes the number of the first connecting arm and the second connecting arm, and can well ensure the rotational stability and reliability of the rotating member on the basis of ensuring the structural stability, thus saving costs.

[0022] Preferably, both the first rolling surface and the second rolling surface are of a segmented structure, and they correspond to each other one by one to form a matching portion for matching with the first ball and the second ball;

[0023] An installation groove is formed between any two adjacent matching portions for installing the second driving member.

[0024] The structure is simple and does not require any extra components to install the second driving component, thereby further reducing the overall volume of the anti-shake gimbal, thereby facilitating miniaturization of the structure.

[0025] Preferably, the bracket and the rotating member are provided with a rotating connecting part 1 and a rotating connecting part 2 which cooperate with each other in the circumferential direction of the gimbal;

[0026] The rotating connection part one or the rotating connection part two both extend along the circumference of the pan-tilt head, specifically in the form of an arc, or one or more segments of an arc. Therefore, on the basis of realizing relative rotation between the rotating part and the bracket, it can ensure the rotation stability of the rotating part, and has the characteristics of simple assembly, thereby improving product yield and reliability. The limiting part three and the limiting part four are arranged at intervals on the rotating part or the bracket to cooperate with the rotating connection part one or the rotating connection part two to limit the rotation angle of the rotating part along the circumference of the pan-tilt head.

[0027] This structure limits the rotation angle of the rotating part, thereby preventing the electromagnetic force between the driving part 1 and the driving part 2 from becoming smaller due to the angle change, thereby avoiding affecting the rotation stability and reliability of the rotating part, thereby meeting the quality requirements.

[0028] Preferably, a metal part is pre-buried in the rotating member or the bracket to be electrically connected to the first driving member or the second driving member.

[0029] This structure simplifies the conduction of the circuit, optimizes the assembly process, and avoids the design cost caused by additional consideration of circuit layout. The structure can also meet the water washing requirements well.

[0030] Preferably, the bracket or the rotating member is made of magnetic conductive material.

[0031] The magnetic conductive material can expand the magnetic field, thereby ensuring the driving reliability of the rotating part by the electromagnetic force.

Through the structure provided by the utility model, the size requirements and driving angle requirements are effectively met, a rational structural design is achieved, and miniaturization requirements are met, thereby effectively improving the practical performance of the pan-tilt head while ensuring the rotation ability of the rotating parts.

Specific embodiments

[0042] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with specific embodiments.

[0043] This embodiment discloses an anti-shake cloud platform, which can be applied to a camera device to achieve stable photographing and / or video recording. Specifically, as Figures 1 to 7 shown, an anti-shake cloud platform includes a first fixing bracket 1, a second fixing bracket 2, a rotating member 3, and a bracket 4; the rotating member 3 is provided with a first driving member 5; the bracket 4 is provided with a second driving member 6, and the bracket 4 is arranged between the first fixing bracket 1 and the second fixing bracket 2; the rotating member 3 is provided with a first rolling surface 12 and a second rolling surface 13, a first ball 14 is arranged between the first rolling surface 12 and the first fixing bracket 1, and a second ball 15 is arranged between the second rolling surface 13 and the second fixing bracket 2; the first rolling surface 12 and the second rolling surface 13 have a curvature along the circumferential direction of the cloud platform, or the contact surfaces between the first fixing bracket 1 and the first ball 14, and between the second fixing bracket 2 and the second ball 15 have a curvature along the circumferential direction of the cloud platform; the first driving member 5 and the second driving member 6 are electromagnetically matched to drive the rotating member 3 to rotate.

[0044] In this embodiment, the first driving member 5 is configured as a magnet, and the second driving member 6 is configured as a coil. The two ends of the bracket 4 are respectively fixedly connected to the first fixing bracket 1 and the second fixing bracket 2. Therefore, when the coil is energized, an electromagnetic force is generated in cooperation with the magnet. When different coils are energized, the rotating member 3 has different rotation intensities, and when the current flow direction is different, the rotation direction of the rotating member 3 can be changed. An FPC circuit board 9 is installed on the bracket 4, and the current can be conducted to the coil through the FPC circuit board 9, so as to meet the driving requirements for the rotating member 3. Specifically, the FPC circuit board 9 is fixed to the bracket 4, the coil is in contact and fixed with the bracket 4 using an adhesive process, and the coil is soldered to the FPC using a spot soldering process, thereby connecting and conducting the circuit. Further, a metal part is embedded in the bracket 4, so as to more simply realize the electrical connection of the second driving member 6.

[0045] Such as Figures 1 to 3As shown, in this embodiment, the rotating member 3 is provided with a first rolling surface 12 and a second rolling surface 13. A first ball 14 is provided between the first rolling surface 12 and the first fixing frame 1, and a second ball 15 is provided between the second rolling surface 13 and the second fixing frame 2. The first rolling surface 12 and the second rolling surface 13 have an arc along the circumferential direction of the pan-tilt. The first ball 14 is fitted between the first rolling surface 12 and the first fixing frame 1, and the second ball 15 is fitted between the second rolling surface 13 and the second fixing frame 2. Therefore, when the rotating member 3 rotates, in addition to satisfying the rotation around the Z-axis, it can also achieve rotation around the X-axis and the Y-axis, thus better meeting the anti-shake requirements. Since the first rolling surface 12 and the second rolling surface 13 have an arc along the circumferential direction of the pan-tilt, during the rotation process, the continuous rotation requirements can be met, avoiding the gap between the ball and the fixing frame when the first rolling surface 12 / the second rolling surface 13 is a plane, so that the rotation smoothness of the rotating member 3 cannot be well guaranteed. Further, since it is also necessary to ensure that the rotating member 3 can rotate well around the X-axis and the Y-axis, in this embodiment, the first rolling surface 12 and the second rolling surface 13 having an arc along the circumferential direction of the pan-tilt are actually spherical segments. As a preferred implementation manner, the center of the spherical segment coincides with the center of the rotating member 3. Therefore, each rotation axis at least substantially passes through the center of the rotating member 3. It can be known that, optimally, each rotation axis passes through the center of the rotating member 3. In this embodiment, the first fixing frame 1 is provided with a first groove portion for installing the first ball 14, and the second fixing frame 2 is provided with a second groove portion for installing the second ball 15. The first fixing frame 1 and the second fixing frame 2 are processed by an injection molding integrated process, making the component precision higher, the size more accurate, and the cost lower. It can also meet different angle requirements only by adjusting the positions and shapes of the upper groove portion 1 and the lower groove portion 2. In some other embodiments, the first groove portion is provided on the first rolling surface 12, and the second groove portion is provided on the second rolling surface 13. At this time, the first fixing frame 1 / the second fixing frame 2 is provided with a contact surface for cooperating with the first ball 14 / the second ball 15. Similarly, the contact surface has an arc along the circumferential direction of the pan-tilt to meet specific usage requirements.

[0046] As Figure 4 and Figure 5As shown, in this embodiment, in order to ensure the rotational reliability of the rotating member 3, the first fixing frame 1 is provided with a first limiting portion 10, and the second fixing frame 2 is provided with a second limiting portion 11. The rotating member 3 is located between the first limiting portion 10 and the second limiting portion 11 to axially limit the rotating member 3 along the pan-tilt axis through the first limiting portion 10 and the second limiting portion 11. Further, the inner top surface of the first fixing frame 1 is configured as the first limiting portion 10, and the second fixing frame 2 is provided with legs, and the free ends of the legs are configured as the second limiting portion 11. Still further, the free ends of the legs have rounded corners to avoid corner contact causing component damage or severe wear. It can be known that since the rotating member 3 can rotate at multiple angles, there are gaps between the rotating member 3 and the first limiting portion 10, and between the rotating member 3 and the second limiting portion 11 in the normal state. Thus, when some coils are energized, an electromagnetic force for the rotating member 3 to rotate around the X axis or an electromagnetic force for the rotating member 3 to rotate around the Y axis can be generated. The rotation of the rotating member 3 is a swing relative to the first fixing frame 1 / the second fixing frame 2. Therefore, the rotation can be limited through the first limiting portion 10 and the second limiting portion 11, thereby ensuring the anti-shake reliability.

[0047] In this embodiment, the arc diameter formed by the movement paths of the first ball 14 and the second ball 15 along the circumference of the pan-tilt is smaller than the maximum diameter of the rotating member 3. Specifically, as Figure 2 and Figure 3 shown, the first ball 14 is located above the pan-tilt, and the second ball 15 is located below the pan-tilt. Obviously, when the first rolling surface 12 and the second rolling surface 13 have a curvature along the circumference of the pan-tilt, the rotating member 3 can press the second ball 15 against the second fixing frame 2, and at the same time, the first fixing frame 1 can press the first ball 14 against the rotating member 3. In this way, the assembly can be conveniently realized, and at the same time, the rotational performance of the rotating member 3 can be ensured. Of course, it also enables this embodiment to be used at any angle relative to the horizontal plane, thereby well expanding the use range of the pan-tilt.

[0048] In this embodiment, the first fixing frame 1 is provided with a first connecting arm 16, and a first mounting portion for mounting the first ball 14 is provided on the end face of the first connecting arm 16 close to the inner side of the pan-tilt; the second fixing frame 2 is provided with a second connecting arm 17, and a second mounting portion for mounting the second ball 15 is provided on the end face of the second connecting arm 17 close to the inner side of the pan-tilt; the first connecting arm 16 and the second connecting arm 17 are arranged in a staggered manner in the circumferential direction of the pan-tilt. It can be known that the first mounting portion is the first groove portion, and the second mounting portion is the second groove portion. Specifically, as Figure 1As shown, let the four corners of the pan-tilt be the first corner direction, the second corner direction, the third corner direction, and the fourth corner direction respectively. The first fixing frame 1 is provided with two opposite connecting arms 16, which are respectively located in the second corner direction and the third corner direction; the second fixing frame 2 is provided with two opposite connecting arms 17, which are respectively located in the first corner direction and the fourth corner direction. In order to save the volume of components and make reasonable use of the component space, the second limiting part 11 provided on the second fixing frame 2 is located in the second corner direction and the third corner direction. Thus, on the basis of ensuring structural stability, the requirements for the stable movement of the rotating part 3 are met.

[0049] As Figure 6 shown, in this embodiment, in order to further simplify the structure, both the first rolling surface 12 and the second rolling surface 13 are segmented structures, and the two correspond to each other to form a matching part 18 for matching the first ball 14 and the second ball 15; an installation groove 19 is formed between any two adjacent matching parts 18 for installing the second driving part 6. Since the second driving part 6 in this embodiment is a magnet, the installation groove 19 is used for assembling the magnet. It should be noted that in this embodiment, there are four magnets. Therefore, in order to meet the requirement that the rotating part 3 can rotate around three axes, four coils are also provided, and the positions of the four coils correspond to the magnets one by one. In order to avoid movement interference during the rotation process of the rotating part 3, both the magnet and the coil are arc-shaped structures.

[0050] As Figure 7As shown, in this embodiment, the bracket 4 and the rotating member 3 are provided with a rotating connection part 1 7 and a rotating connection part 2 8 that cooperate with each other in the circumferential direction of the gimbal; a limiting part 3 20 and a limiting part 4 21 are provided at intervals on the bracket 4 to cooperate with the rotating connection part 1 7 or the rotating connection part 2 8 to limit the rotation angle of the rotating member 3 along the circumferential direction of the gimbal. In this embodiment, the rotating member 3 is arranged on the inner side of the bracket 4, and the inner side of the bracket 4 is provided with a rotating connection part 1 7 with a groove structure, and the outer side of the rotating member 3 is provided with a rotating connection part 2 8 with a protruding structure. Therefore, through the cooperation of the rotating connection part 1 7 and the rotating connection part 2 8, the rotating member 3 can be well positioned on the inner side of the bracket 4, so as to facilitate the assembly and positioning of the two. It is known that in another implementation of this embodiment, the rotating connection part 1 7 can also be configured as a protruding structure, and the rotating connection part 2 8 can be configured as a groove structure. It can also be known that in some other embodiments, the rotating member 3 is positioned on the outside of the bracket 4. At this time, the rotating connection part 1 7 is arranged on the outside of the bracket 4, and the rotating connection part 2 8 is arranged on the inside of the rotating member. In this embodiment, similarly, one of the rotating connection part 1 7 and the rotating connection part 2 8 is a groove structure, and the other is a protruding structure. Specifically, there are two groups of the limiting part 3 20 and the limiting part 4 21, one of which is located in the first angular direction and the other is located in the fourth angular direction. The limiting part 3 20 and the limiting part 4 21 can limit the movement stroke of the rotating connection part 2 8, thereby realizing the angular limit of the rotating frame rotating around the Z axis, thereby ensuring the rotation reliability of the rotating member 3. It can be known that when the rotating connection part 1 7 is a protruding structure, the limiting part 3 20 and the limiting part 4 21 are arranged at intervals on the rotating member 3 to meet specific use requirements. It should be noted that in order to ensure the multi-directional rotation reliability of the rotating member 3, there is a gap between the rotating connection part 1 7 and the rotating connection part 2 8.

[0051] In this embodiment, since the coil is arranged on the bracket 4, a metal part is embedded in the bracket 4 to be electrically connected to the driving part 2 6 configured as a coil, thereby driving the rotating part 3. At this time, since the driving part 1 5 is configured as a magnet, the rotating part 3 is made of a magnetic conductive material to enhance the magnetic field.

[0052] Based on the above embodiments, it is known that in some other embodiments, the driving member 1 5 is configured as a coil and the driving member 2 6 is configured as a magnet. In this case, the same technical effect as the above embodiments can be achieved, and no further description is given here. It is known that in this embodiment, the rotating frame is pre-embedded with metal parts, and the bracket 4 is made of magnetic conductive material. At this time, since the coil set on the rotating frame needs to be energized, the FPC circuit board 9 can be set on the bracket 4, and then the real-time conduction of the current is ensured through the sliding contact sheet.

[0053] Based on the above embodiments, it can be known that in some other embodiments, the first driving member 5 is configured as a coil, and the second driving member 6 is configured as a magnet. At this time, the same technical effects as those in the above embodiments can also be achieved, and details will not be elaborated here.

[0054] Therefore, when assembling this embodiment, grease is dispensed in the first groove portion using a dispensing process, and then the first ball 14 is assembled into the first groove portion on the first fixing bracket 1. Then, the first fixing bracket 1 and the bracket 4 are adhesively fixed using an adhesive process. Next, the magnet is fixed to the mounting groove 19 of the rotating member 3 through an adhesive process, and then the rotating member 3 is placed on the bracket 4. Grease is dispensed in the second groove portion using a dispensing process, and then the second ball 15 is assembled into the second groove portion on the second fixing bracket 2. Then, the second fixing bracket 2 and the bracket 4 are adhesively fixed using an adhesive process. During the above process, the first ball 14 supports the first fixing bracket 1, and the second ball 15 supports the first fixing bracket and the rotating member 3.

[0055] During use, the bracket 4, the first fixing bracket 1, and the second fixing bracket 2 are in a fixed state relative to the entire pan-tilt head. After the current passes through the FPC inside the bracket 4 and energizes the coil, an electromagnetic force is generated between the coil and the magnet on the rotating member 3, generating a force for the rotating member 3 to rotate around the X-axis or Y-axis or Z-axis, causing the rotating member 3 to undergo a large-angle displacement, thereby achieving anti-shake. By controlling the current direction, magnitude, and the energization conditions of different coils, the rotation control of the rotating member 3 is realized, so as to cancel the vibration interference generated during shooting, avoid image blurring, and improve the imaging quality of the video and / or photo.

[0056] The above is only the preferred embodiment of the present invention. It should be noted that the above preferred embodiment should not be regarded as a limitation to the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art, without departing from the spirit and scope of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
