Telescopic rotating mechanism and portable electronic device

The present invention relates to a telescopic rotating mechanism, and in particular, to a telescopic rotating mechanism for an image capturing module of a portable electronic device.

In today's mobile communication technology, it has become a trend to combine various functions in a single portable electronic device. Among the portable electronic devices, mobile phones are most widely used by the general public. Therefore, all parties are not devoted to researching functions of mobile phones in addition to communication. For example, mobile phones on the market have combined functions such as computers, web browsing, photography, multimedia playback or digital assistants.

Among them, the combination of camera functions in mobile phones has become one of the main functions of most phones. In addition, because of the advent of the 3G mobile phone era, mobile phones can also be used for video calls. The same image module can be used for photographing and video calling in a 3G mobile phone. The image module usually has two lenses for performing photography and video calling functions.

The lenses of the above mobile phones are generally located on the front and back of the mobile phone, respectively. The photographic lens is usually placed on the back side (opposite the screen where the mobile phone is located) for the user to view. The video call lens is usually placed on the front side (the screen where the mobile phone is located), so that the user can watch the other party while capturing his own image by using the mobile phone.

However, since both sets of lenses are used at the same time, the manufacturing cost will increase. In addition, since the lens is located on the front and back of the mobile phone, it will occupy more screen surface or battery surface area, and the externally designed external components for protecting the lens will limit the design of the mobile phone. On the other hand, since the camera lens itself is fixedly disposed on the mobile phone, when the framing is performed at different angles, the mobile phone needs to be rotated correspondingly, which sometimes causes the user to inconveniently observe the condition of the screen.

Therefore, one aspect of the present invention is to provide a telescopic rotating mechanism that can be used in an image capturing module of a portable electronic device to solve the above problems.

According to a specific embodiment, the telescopic rotating mechanism of the present invention includes a connecting member, a sleeve member, an elastic member, a first telescopic member, and a second telescopic member. The connecting member has a fixed structure to fix the sleeve structure on the connecting member. The inner wall of the sleeve member may be provided with a sliding structure, and the sliding structure has at least one first groove and at least one second groove. Wherein the first groove and the second groove extend along the axial direction of the sleeve member, and the first diameter from the axis of the sleeve member to the first groove is greater than the second diameter from the axis to the second groove diameter.

In this particular embodiment, the resilient member contacts the connecting member and is disposed within the sleeve member. The first telescopic member then contacts the elastic member and is also located within the sleeve member, the periphery of the first telescopic member having at least one first protruding rib, from the axis of the first telescopic member to the third diameter of the first protruding rib Greater than the second diameter and smaller than the first diameter, the first protruding rib can slide within the first groove. Further, one end of the first protruding rib has a beveled edge. The second telescopic member portion is located in the sleeve member, and has a wavy edge at one end to contact the oblique side of the first protruding rib, and the other end is in contact with the image capturing module. The beveled edge of the first protruding rib is slidable along the undulating edge, such that the second telescopic member is rotatable relative to the first telescopic member by sliding of the beveled edge and the undulating edge. In addition, at least one second protruding rib is disposed on a periphery of the second telescopic member, and a fourth diameter of the second telescopic member to the second protruding rib is smaller than the second diameter, so that the second protruding rib can be respectively A groove and a second groove slide.

In this embodiment, when the first protruding rib of the first telescopic member is engaged with the sliding structure and/or the second groove to compress the elastic member, the telescopic rotating mechanism is in a contracted state. On the other hand, when the first projecting ribs overlap the first groove, the elastic restoring force of the elastic member urges the first telescopic member to slide within the sleeve member, causing the telescopic rotating mechanism to be in an extended state.

Another aspect of the present invention is to provide a portable electronic device in which an image capturing module can perform a telescopic movement by a telescopic rotating mechanism.

According to a specific embodiment, the portable electronic device of the present invention comprises an image capturing module and a telescopic rotating mechanism contacting the image capturing module.

The image capturing module can be controlled by the telescopic rotating mechanism to extend from the portable electronic device or to be used in the portable electronic device. The rotation angle of the image capturing module is changed by the telescopic rotating mechanism.

Referring to FIG. 1, FIG. 1 is a schematic view showing a telescopic rotating mechanism 1 according to an embodiment of the present invention. As shown in FIG. 1, the telescopic rotating mechanism 1 includes a connecting member 10, a sleeve member 12, an elastic member 14, a first telescopic member 16, and a second telescopic member 18. In practice, the resilient member 14 can be an elastomer that provides an elastic restoring force to the first telescoping member 16, such as, but not limited to, a spring. Further, in practice, the connecting member 10, the sleeve member 12, the elastic member 14, the first telescopic member 16, and the second telescopic member 18 are substantially cylindrical.

In the present embodiment, the connecting member 10 has a first fixing structure 100 that can be engaged with the second fixing structure 102 of the sleeve member 12 to fix the sleeve member 12 above the connecting member 10. The resilient member 14 is located within the sleeve member 12 and is disposed between the connecting member 10 and the first telescoping member 16, wherein one end of the resilient member 14 can contact the connecting member 10 and the other end can contact the first telescoping member 16.

Please note that this rotation is phased, for example, when the second telescopic member 18 is subjected to the external force F1 once, and the first protruding rib 160 is moved from the bottom of one of the originally contacted wavy edges 180 to the other adjacent bottom.

2B to FIG. 2D, FIG. 2B is a schematic cross-sectional view of the sleeve member 12 of FIG. 1; FIG. 2C is a schematic cross-sectional view of the first telescopic member 16 of FIG. 1; A schematic cross-sectional view of the second telescopic member 18 of FIG. As shown in FIG. 2B, FIG. 2C and FIG. 2D, in the specific embodiment, the inner wall of the sleeve member has a sliding structure 120, wherein the sliding structure 120 is provided with three first grooves 1200 and three a second groove 1202, and the first groove 1200 and the second groove 1202 extend in the axial direction of the sleeve member 12; the first telescopic member 16 has three first protruding ribs 160; the second telescopic member 18 has six Second protruding ribs 182. Please note that in practice, the number of the first protruding ribs 160, the second protruding ribs 182, the first grooves 1200, and the second grooves 1202 is determined according to the needs of the user or the designer, and is not limited to the present specification. The number of specific embodiments is listed.

In the present embodiment, the first diameter D1 from the axis of the sleeve member 12 to the first groove 1200 is greater than the axis of the sleeve member 12 to the second diameter D2 of the second groove 1202. The third diameter D3 of the first telescopic member 16 to the periphery of the first protruding rib 160 is between the first diameter D1 and the second diameter D2, that is, when the first telescopic member 16 is in the sleeve member 12 When sliding in the middle, the first protruding rib 160 can slide in the first groove 1200 and cannot slide in the second groove 1202. The fourth diameter D4 of the second telescopic member 18 to the periphery of the second protruding rib 182 is smaller than the second diameter D2. Further, in the specific embodiment, the fourth diameter D4 is greater than the axial center of the sleeve member 12. To the diameter of the sliding structure 120, the second protruding rib 182 can slide in the first groove 1200 and the second groove 1202 when the second telescopic member 18 slides in the sleeve member 12.

Please refer to FIG. 2A, FIG. 3A and FIG. 3B together. FIG. 3A shows the sleeve member 12, the first telescopic member 16 and the second telescopic member 18 in the contracted state of the telescopic rotating mechanism 1 of FIG. FIG. 3B is a schematic view showing the relative positions of the sleeve member 12, the first telescopic member 16, and the second telescopic member 18 in the extended state of the telescopic rotating mechanism 1 of FIG.

As shown in FIG. 3A, when the telescopic rotating mechanism 1 is in the contracted state, the first protruding rib 160 of the first telescopic member 16 abuts against the second groove 1202. Please note that in practice, when the telescopic rotating mechanism 1 is in the contracted state, the first protruding rib 160 of the first telescopic member 16 can also abut against the sliding structure 120. On the other hand, as shown in FIG. 3B, when the telescopic rotating mechanism 1 is in the extended state, the first protruding rib 160 of the first telescopic member 16 is located in the first groove 1200.

In the present embodiment, if the telescopic rotating mechanism 1 is in the contracted state (as shown in FIG. 3A), and the second telescopic member 18 receives the force F1 of FIG. 2A, the first telescopic member 16 will be secondly telescoped. The member 18 pushes and further compresses the elastic member 14. Next, when the external force F1 is stopped from being applied to the second telescopic member 18, the elastic restoring force F2 of the elastic member 14 pushes the first telescopic member 16 and the second telescopic member 18 while the oblique side 1600 on the first protruding rib 160 The wavy brim 180 slides, and the first telescopic member 16 rotates relative to the second telescopic member 18 to the first protruding rib 160 to overlap the first groove 1200, so that the first telescopic member 16 and the second telescopic member 18 are combined. The sleeve member 12 slides, and the telescopic rotating mechanism 1 is stretched (as shown in FIG. 3B).

On the other hand, when the telescopic rotating mechanism 1 is in the extended state (as shown in FIG. 3B), and the second telescopic member 18 receives the force F1 outside FIG. 2A, the second telescopic member 18 pushes the first telescopic member 16 together. The sleeve member 12 slides toward the connecting member 10, and the first protruding rib 160 of the first telescopic member 16 slides in the first groove 1200. After the first protruding rib 160 slides out of the first groove 1200, the first telescopic member 16 can slide along the undulating edge 180 by the oblique side 1600 on the first protruding rib 160 shown in FIG. A telescoping member 16 rotates relative to the second telescoping member 18. Then, when the external force F1 is stopped from being applied to the second telescopic member, the elastic restoring force F2 of the elastic member 14 pushes the first telescopic member 16 and the second telescopic member 18 while the first telescopic member 16 rotates relative to the second telescopic member 18. The first protruding rib 160 is caused to abut against the sliding structure 120 and/or the second groove 1202, thereby causing the telescopic rotating mechanism 1 to be in a contracted state (as shown in FIG. 3A). In addition, the second protruding rib 182 on the second telescopic member 18 can be designed to contact the second groove 1202 of the sleeve member 12, so that the second groove 1202 can provide a frictional force to the second protruding rib 182. When the telescopic rotating mechanism 1 is in the contracted state, the second telescopic member 18 does not easily slide out of the sleeve member 12.

The fixed end 190 of the hinge 19 can be connected to the portable electronic device 3, and the rotating end 192 of the hinge 19 is connected to the connecting member 10. By the hinge 19, the telescopic rotating mechanism 1 can drive the image capturing module 2 relative to the portable type. The electronic device 3 is rotated, whereby the user of the portable electronic device 3 can adjust the image capturing module 2 relative to the portable electronic device 3 to any angle he/she desires. In practice, the hub 19 can be coupled to the portable electronic device 3 and the connecting member 10 by, but not limited to, screws. The components of the telescopic rotating mechanism 1 of the present embodiment are the same as those of the above-described specific embodiments, and will not be described herein.

In the present embodiment, the image capturing member 22 can be received in the fixture 20 and the fixture 20 can contact the second telescoping member 18. The image capture unit 22 further includes a lens 220 for capturing an image and a signal soft board 222 coupled to a control/processing unit (not shown) of the portable electronic device 3. The lens 220 can be aligned with the hole 200 in the device 20 for image capture, and the signal soft board 222 can be wrapped by the notch 202 on the device 20 to be wound around the device 20.

When the telescopic rotating mechanism 1 is in the extended state, the resisting structure 204 can be pressed against the inner wall of the portable electronic device 3 to prevent the image capturing module 3 from rotating and rotating. The mechanism 1 is damaged by the drop of the portable electronic device 3.

Compared with the prior art, the telescopic rotating mechanism of the present invention and the portable electronic device using the telescopic rotating mechanism can assist the image capturing module to extend or revenue from the portable electronic device, and can capture the image capturing mode. The group is rotated. In this way, a set of lens modules can be used for video call and camera functions, thereby saving production costs. In addition, when performing special angle framing, the user can directly rotate the image capturing module without rotating the entire portable electronic device, which makes it inconvenient for the user to view the screen. Furthermore, when the image capturing module is not used, it is stored in the portable electronic device, which can effectively prevent the lens from being scratched or contaminated with dust and prolonging its service life.
