Description

Technical Field

[0001] The present invention relates to the technical field of photographic equipment, and in particular to a vibration reduction and anti-shake mechanism, a lens assembly and a photographing device. Background Art

[0002] With the improvement of high-definition technology in the market, people have higher and higher requirements for the clarity of the pictures they shoot. To improve the clarity of the pictures, it is necessary to solve the problem of lens anti-shake. At present, the mainstream anti-shake mechanism used in lenses is the ball-type anti-shake mechanism, see Figure 1 As shown, the current anti-shake mechanism includes an upper fixed seat 1', a lower fixed seat 2', a moving member 4', a spring 3', a ball 5' and two ball sheets 7'. The lower fixed seat 2' and the moving member 4' are movably connected through the spring 3'. The upper end surface of the moving member 4' is provided with a ball sheet 7'. The lower end surface of the upper fixed seat 1' is provided with a sink groove 11'. Another ball sheet 7' is placed in the sink groove 11'. The ball 5' movably abuts between the two ball sheets 7' and can only move in the sink groove 11'.

[0003] When the camera shakes during shooting, the camera will drive the moving parts to move relative to each other according to the shaking vector to compensate for the impact of the shaking on the lens, thereby ensuring the clarity of the captured image. During this process, the anti-shake mechanism can stabilize the movement of the moving parts to a certain extent and ensure the movement accuracy of the moving parts.

[0004] However, during the relative movement of the moving parts, the balls move freely in the grooves and are prone to collide with the inner wall of the grooves to generate vibrations, affecting the stability of the anti-shake mechanism. In addition, the balls and the ball plate have different matching sizes when they are in contact at different positions, which requires a very high overall flatness accuracy of the ball plate, increasing the production cost.

[0005] The main movement of the moving part is the swing on the plane, and the swing direction is parallel to the two ball bearings. When making the ball bearings, it is necessary to ensure the flatness of the ball bearings, and when installing, it is also necessary to ensure the parallelism between the two ball bearings. The precision requirements for manufacturing are very high, resulting in increased production costs and product defect rates. In addition, when the moving part swings, the spring undergoes radial deformation accordingly, and the spring itself is made of a spirally wound rigid material. During the high-speed movement of the moving part, the spring will cross its axis during the return movement. The restoring force of the spring will interfere with the normal operation of the moving part, causing fluctuations and vibrations of the moving part, affecting the quality and stability of the image captured by the lens.

[0006] Secondly, the two ends of the spring are respectively in contact with the moving part and the lower fixed seat, and the end of the spring can undergo a slight radial displacement relative to the moving part or the lower fixed seat, further affecting the working effect of the anti-shake mechanism and thus affecting the stable picture output by the lens. Summary of the invention

[0007] In order to overcome the shortcomings of the prior art, one of the objects of the present invention is to provide a shock-absorbing and anti-shake mechanism that can prevent the ball from freely colliding with the wall and has a buffering and shock-absorbing effect on the moving parts; the second object is to provide a lens assembly with the above-mentioned shock-absorbing and anti-shake mechanism; the third object is to provide a shooting device with the above-mentioned shock-absorbing and anti-shake mechanism.

The structure of the accommodating channel is easy to manufacture, and when installing the ball, it is only necessary to put the ball into the internal channel of the pipe from the top, and then install the planar member on the pipe to close the upper end of the internal channel of the pipe, thereby limiting the ball within the accommodating channel. In other embodiments, the accommodating channel can also be replaced by a hemispherical shape that matches the ball, and a through hole is opened at the bottom of the hemispherical accommodating channel for the ball to partially extend out.

[0016] In some embodiments of the present invention, a plurality of strip ribs extending upward and distributed in a circumference are provided on the first rubber sleeve, and the plurality of strip ribs together form a circular fence structure for being fitted and fixed on the outside of the first insertion portion.

[0028] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0029] Reference Figure 2 , Figure 3 and Figure 4The present invention provides a shock absorbing and anti-shake mechanism, comprising: an upper fixed seat 1, a lower fixed seat 2, an elastic member 3, a moving member 4 and a ball 5, wherein the moving member 4 is movably connected to the lower fixed seat 2 through the elastic member 3, the moving member 4 is located between the upper fixed seat 1 and the lower fixed seat 2, and the ball 5 is movably arranged between the upper fixed seat 1 and the moving member 4, and is characterized in that a fixed sleeve 6 is arranged on one of the upper fixed seat 1 and the moving member 4, and a ball sheet 7 opposite to the fixed sleeve 6 is arranged on the other, and a ball sheet 7 opposite to the fixed sleeve 6 is arranged in the fixed sleeve 6 to accommodate the ball sheet 7. The ball 5 also includes an accommodating channel for the ball 5 to rotate relative to it, and the ball 5 partially extends out of the accommodating channel and makes point contact with the ball sheet 7.

[0030] The shock-absorbing and anti-shake mechanism of the above structure replaces the original ball plate 7 with a fixing sleeve 6. When the movable part 4 moves relative to the upper fixing seat 1, the ball 5 rolls on the ball plate 7 and can only rotate in the accommodating channel, so as to prevent the ball 5 from freely hitting the wall, thereby ensuring the working stability of the shock-absorbing and anti-shake mechanism, and only the installation accuracy of the ball plate 7 needs to be ensured during the assembly process; the elastic part 3 with a rubber connecting part 32 is used to replace the traditional spring. The rubber connecting part 32 has a buffering and shock-absorbing effect on the reset movement of the movable part 4, thereby avoiding interference with the normal movement of the movable part 4, ensuring the accuracy of the shock-absorbing and anti-shake mechanism, and further ensuring the stability of the image output by the lens.

[0031] See also Figure 3 and Figure 4 In some embodiments of the present invention, preferably, the fixing sleeve 6 comprises a pipe 61 and a plane member 62, wherein the plane member 62 is used to close the upper end of the internal channel of the pipe 61, and the lower end of the internal channel of the pipe 61 has a constricted portion 611 to form the accommodating channel, and the side of the ball 5 away from the constricted portion 611 contacts the inner surface of the plane member 62. In order to ensure the durability and stability of the fixing sleeve 6, the pipe 61 and the plane member 62 are both made of metal material to ensure that the plane member 62 is not easily worn when the ball 5 rotates relative to the accommodating channel. The structure of the accommodating channel is easy to manufacture, and when installing the ball 5, it is only necessary to put the ball 5 from the upper part of the internal channel of the pipe 61, and then install the plane member 62 on the pipe 61 to close the upper end of the internal channel of the pipe 61, thereby limiting the ball 5 in the accommodating channel. In other embodiments, the accommodating channel can also be replaced by a hemispherical shape that matches the ball 5, and a through hole is opened below the hemispherical accommodating channel for the ball 5 to partially extend.

[0035] See also Figure 5 It is further preferred that an overflow through hole 12 connected to the contoured sink groove 11 is opened on the upper fixing seat 1. When the flange plate 613 is fixed to the contoured sink groove 11 by glue, if there is too much glue, it will cause relative inclination between the fixing sleeve 6 and the upper fixing seat 1, affecting the working accuracy of the anti-shake mechanism. The overflow through hole 12 can discharge excess glue therein to ensure the installation accuracy of the fixing sleeve 6. In addition, the glue in the overflow through hole 12 is still connected to the fixing sleeve 6 after curing, which helps to ensure the stability of the connection of the fixing sleeve 6.
