The present disclosure is directed to an optical instrument component, and more particularly to a lens barrel device that is mounted within an optical instrument.

In recent years, the trend of handheld imaging devices such as mobile phones, PDAs, digital cameras, and cameras has become increasingly common, with the demand for handheld devices, better performance, and smaller market demand. Optical imaging modules have faced the dual requirements of higher image quality and miniaturization. In addition to improving the clarity of optical imaging pixels and image capture, the shock-proof design of handheld devices is becoming increasingly important.

In order to increase the anti-vibration effect of the lens unit of the optical instrument, the conventional tube is prevented from being shaken and abnormally sounded by the instantaneous force due to the instantaneous force, and a separate buffering member is generally added between the group tube and the fixed tube. The additional buffer member not only causes an increase in manufacturing cost and inconvenience to the process, but also has the problem that the performance of both the repaired component and the initial buffer member cannot be ensured to be the same, and the external cushioning member may cause difficulty in assembly work. Increase in work and hours of work.

Therefore, one aspect of the present disclosure is to provide a lens anti-shake device that not only overcomes the jitter and abnormal sound generated by the instantaneous force of the group cylinder, but also overcomes the cost increase and inconvenience of the external buffering device. Poor repairability, increased difficulty in work, and increased hours of work.

According to an embodiment of the present technology, a lens anti-shake device is provided, which comprises a fixed cylinder and a group of cylinders. The group tube is coaxially sleeved in the fixed cylinder, and the group cylinder is movable relative to the fixed cylinder. The group cylinder comprises at least one buffer portion formed by the group cylinder integrally forming a radial protrusion, the buffer portion abuts against the inner wall of the fixed cylinder, and buffers A permeable area is formed in the portion to provide a space for the buffer portion to be deformed.

In other embodiments of the present technical aspect, both sides of the permeable area are closed, and the buffer portion abuts against the inner wall of the fixed cylinder, and is curved along the contour of the inner wall of the fixed cylinder and extends in an arc shape. The buffer portion further includes a support area and an abutment area. The support zone is formed by a group of cylinders integrally formed in a radial direction. The abutment zone connects the support zone to form the aforementioned through-space zone, and the thickness of the abutment zone is less than the thickness of the support zone. In addition, the buffer portion may be tapered to form a convex shaped buffer portion. It is worth mentioning that the convex shaped buffer portion abuts against the inner wall of the fixed cylinder, and is curved along the contour of the inner wall of the fixed cylinder and extends in an arc shape.

In addition, in other embodiments of the present technical aspect, the through-space region may also be in a form in which one side is closed and the other side is open, and the buffer portion abuts against the inner wall of the fixed cylinder, and is curved with the contour of the inner wall of the fixed cylinder. It extends in an arc shape. The buffer portion further includes a support area and an abutment area. The support zone is formed by a group of cylinders integrally formed in a radial direction. The abutment zone connects the support zone to form the aforementioned through-space zone, and the thickness of the abutment zone is less than the thickness of the support zone. In addition, the buffer portion abuts against the inner wall of the fixed cylinder, and is curved along the contour of the inner wall of the fixed cylinder and extends in an arc shape.

Therefore, the above embodiments achieve the shock absorbing effect by integrally forming the buffer portion on the group cylinder, and also solve the problem of increasing the cost of the conventional external buffering member, inconvenient process, poor repairability, difficulty in operation, and increase in working hours. The problem.

FIG. 1 is a perspective view of a lens anti-shake device according to an embodiment of the present disclosure. As shown in FIG. 1, the lens anti-shake device 100 includes a fixed cylinder 110 and a plurality of cylinders 120. The specially designed group cylinder 120 of the present embodiment not only can solve the jitter and abnormal sound generated by the instantaneous stress of the group cylinder 120, but also increases the cost of the conventional external buffering unit, inconvenience in the process, poor repairability, and difficulty in operation. The problem of increased working hours can also be improved.

Fig. 2 is a rear elevational view of the lens anti-shake device of Fig. 1. Fig. 3 is an exploded view of the lens anti-shake device of Fig. 1. As shown in FIG. 2 and FIG. 3, the group cylinder 120 is coaxially sleeved in the fixed cylinder 110, and the group cylinder 120 is movable relative to the fixed cylinder 110. The group cylinder 120 includes at least one buffer portion 121, and the group cylinder 120 is integrally formed. The protrusion portion is formed, and the buffer portion 121 abuts against the inner wall of the fixed cylinder 110. The buffer portion 121 is integrally formed by the group cylinder 120. On the one hand, the structural strength of the buffer portion 121 can be increased, and on the other hand, the cost can be reduced and the processing convenience can be improved.

It should be noted that the buffer portion 121 may be disposed parallel to the outer edge C of the group cylinder 120, or may be disposed at an angle α between the buffer portion 121 and the outer edge C of the group cylinder 120 in the present embodiment. However, there are many ways in which the buffer portion 121 and the group cylinder 120 are disposed. As long as the buffer portion 121 can sufficiently abut the fixed cylinder 110 and achieve the shock absorbing effect, there is no limitation on the manner of installation.

A buffering portion 121 is formed in the buffer portion 121 of the present embodiment to provide a space for the buffer portion 121 to be deformed. In other words, when the buffer portion 121 is subjected to an external force, it can be elastically deformed by the through-hole region 122. Resist the external forces that are exposed to the moment. The two sides of the permeable portion 122 are closed, and the buffer portion 121 is bent at the inner wall of the fixed cylinder 110 and extends along the contour of the inner wall of the fixed cylinder and extends in an arc shape. The apex of the buffer portion 121 is curved and fixed. The force is applied to the grouping point A of the group cylinder, and the buffer portion 121 is curved in the inner wall of the fixed cylinder 110 so as to be biased to the group cylinder 120 by the uniform and fixed point of application A. In this way, not only the forces on both sides of the buffer portion 121 are relatively uniform, but also the service life of the buffer portion 121 is further increased.

In the present embodiment, the two sides of the buffer portion 121 are tapered to form a convex shaped buffer portion along with the arc. However, although the buffer portion 121 of the present embodiment is tapered to form a convex shape, so that the center of the buffer portion 121 protrudes against the inner wall of the fixed cylinder 110, the design is only for the fixed and fixed force point A of the fixed cylinder 110. Apply force to the group 120. Therefore, the buffer portion 121 is not only in a convex shape, but the buffer portion 121 can also be a simple arc-shaped shape, and also has the effect of providing a point of application. As for the shape of the buffer portion 121, it can be adjusted according to the requirements of the manufacturing process, the abutting force requirement, and the processing cost.

In addition, the buffer portion 121 further includes a support area 123 and an abutment area 124. The support region 123 is formed by integrally forming the group cylinder 120 in a radial direction. The abutment zone 124 connects the support zone 123 to form the aforementioned permeable zone 122. The support region 123 is connected to the abutment region 124 on the one hand, and provides a supporting force to the abutment region 124 when the abutment region 124 is elastically deformed by an external force.

In the present embodiment, the thickness of the abutment region 124 is smaller than the thickness of the support region 123. The thickness of the support region 123 is thick to provide sufficient support force to the top region. 124, and the thickness of the abutment region 124 is thin in order to reduce the difficulty of elastic deformation.

FIG. 4 is a front view of a lens anti-shake device according to another embodiment of the present disclosure. As shown in FIG. 4, the lens anti-shake device 200 of the present embodiment is substantially the same as the lens anti-shake device 100 of the foregoing embodiment, except that the transparent area 210 of the present embodiment is closed on one side, and the other is closed. The side open form can effectively increase the degree of elastic deformation of the buffer portion 220 and the effect of shock absorption. The rest of the embodiment is the same as the foregoing embodiment, and details are not described herein.

According to the above embodiment, the lens anti-shake device of the present disclosure achieves the effect of shock absorption and noise prevention by integrally forming the buffer portion on the group cylinder, and also solves the cost increase and process of the conventional external buffer component. Inconvenience, poor repairability, increased difficulty in work, and increased working hours. In addition, the buffer portion can be in various forms, and the buffer portion can be adjusted in accordance with various usage requirements.

The present disclosure has been disclosed in the above embodiments, and is not intended to limit the scope of the disclosure, and thus, various modifications and refinements may be made without departing from the spirit and scope of the disclosure.
