Description
Technical field
The utility model relates to the user terminal field, is specifically related to a kind of camera rotating shaft.
Background technology
All dispose camera on the user terminals such as many computers of using, mobile phone at present, the mounting means of this camera in user terminal usually as shown in Figure 1, Fig. 1 is the camera rotating shaft of camera, prior art and the assembling schematic diagram of user terminal casing.
Wherein, fixed cylinder 3 is installed in the user terminal casing 2, and fixed cylinder 3 and user terminal casing 2 relative being maintained fixed, and the two neither moves to axial, and does not also relatively rotate.One end of rotating cylindrical 4 is installed in the fixed cylinder 3, the other end and camera 1 fixed installation.Rotating cylindrical 4 and fixed cylinder 3 are metalwork.Rotating cylindrical 4 and fixed cylinder 3 coaxial and maintenance axial restraints, but rotating cylindrical 4 can 3 rotations of relative fixed cylinder.Rotating cylindrical 4 neither moves to axial with camera 1, does not also relatively rotate.
When user's rotating camera 1,,, the two rotates so keeping synchronous because camera 1 is fixedly mounted on the rotating cylindrical 4; Again because rotating cylindrical 4 can rotate by relative fixed cylinder 3, so the user finally can be implemented in rotating camera 1 on the user terminal casing 2.
Rotating cylindrical 4 among Fig. 1 is installed together formed device with fixed cylinder 3, is commonly called the camera rotating shaft.More concrete description at this camera rotating shaft is arranged in Fig. 2, and Fig. 2 is the camera rotating shaft schematic perspective view of prior art.
Among Fig. 2, rotating cylindrical 4 is installed in the fixed cylinder 3, and rotating cylindrical 4 keeps axial restraint with fixed cylinder 3, but rotating cylindrical 4 can 3 rotations of relative fixed cylinder.Angle limits pin 11 is installed on the rotating cylindrical 4, and angle limits pin 11 is generally metalwork.When 3 rotations of rotating cylindrical 4 relative fixed cylinders, angle limits pin 11 can be blocked by the first rotation block face 5 and the second rotation block face 6, makes the rotating cylindrical 4 that angle limits pin 11 is installed to rotate in the certain angle scope.
Have, angle limits pin 11 compresses mutually with the first axial block face 7 on the fixed cylinder 3 again, make fixed cylinder 3 and rotating cylindrical 4 each other can't be axially away from.In fact, also have other structural relation between fixed cylinder 3 and the rotating cylindrical 4, can't further move axially to fixed cylinder 3 inside with assurance rotating cylindrical 4, but not show in Fig. 2, this structural relation will be described in Fig. 4.
On the rotating cylindrical 4 except angle limits pin 11 is installed, also angle location part 9 is installed in embedded mode, outstanding protruded stigma 10 is arranged in angle location part 9, protruded stigma 10 matches with ring gear 8 on the fixed cylinder 3, that is: protruded stigma 10 can be absorbed in the mark of mouth between any two adjacent internal tooths on the ring gear 8.When rotating cylindrical 4 rotates in fixed cylinder 3, protruded stigma 10 can be absorbed in the mark of mouth between any two adjacent internal tooths on the ring gear 8, make rotating cylindrical 4 when the rotation external force that is not subjected to from the user, can keep relative fixed with fixed cylinder 3 because of protruded stigma 10 has been absorbed in the described mark of mouth, can rotation voluntarily on fixed cylinder 3.
Like this, after described camera that the user will be fixedlyed connected with rotating cylindrical 4 rotates to its required angle, just can unclamp hand relievedly, rotating cylindrical 4 natures can be in its present located anglec of rotation, and can not rotate voluntarily, make described camera can be in its present located anglec of rotation naturally, and can not rotate voluntarily.
Referring to Fig. 3 A, Fig. 3 A is the angle location part front view of prior art.As known in the figure, angle location part 9 comprises keeper housing 12 and protruded stigma 10, and protruded stigma 10 can move up and down by relative positioning spare housing 12.
Referring to Fig. 3 B, Fig. 3 B is the angle location part broken section front view of prior art.This figure is the same with Fig. 3 A, all is the front view of angle location part 9, just among Fig. 3 B the first half of keeper housing 12 has been carried out analysing and observe processing.As seen, in keeper housing 12, be provided with spring 13, be used for protruded stigma 10 is applied the thrust of certain intensity.Also applied thrust, just made protruded stigma 10 can give prominence to keeper housing 12 and be absorbed in the mark of mouth between any two adjacent internal tooths on the described ring gear just because of 13 pairs of protruded stigmas 10 of spring.
Referring to Fig. 4, Fig. 4 is the camera rotating shaft partial cross-sectional perspective view of prior art.Wherein, the projection 16 of rotating cylindrical 4 is provided with very little step-like chucking hook 17, and chucking hook 17 compresses mutually with the first axial block face 7 on the fixed cylinder 3, make fixed cylinder 3 and rotating cylindrical 4 each other can't be axially away from.
Have, the face 15 of axially being close on axial block face 14 of second on the fixed cylinder 3 and the rotating cylindrical 4 compresses mutually, makes rotating cylindrical 4 further to move axially to fixed cylinder 3 inside again.
Like this, rotating cylindrical 4 just can keep axial restraint with fixed cylinder 3.In addition, rotating cylindrical 4 when rotated, projection 16 can by first the rotation block face 5 and second the rotation block face 6 not block.
When fixed cylinder 3 and rotating cylindrical 4 are assembled, because rotating cylindrical 4 is hard metalworks, if rotating cylindrical 4 levels are put in fixed cylinder 3, chucking hook 17 can push up on the second axial block face 14, causes fixed cylinder 3 and rotating cylindrical 4 to assemble.Therefore, need earlier rotating cylindrical 4 slight inclination to be probeed in fixed cylinder 3, chucking hook 17 is pressed on the first axial block face 7.Afterwards, on rotating cylindrical 4, insert angle limits pin 11 again.
By the above as seen, the described camera rotating shaft of using in the prior art has two than significant disadvantages, first shortcoming is: because the user rotates the frequency of camera, make the local surfaces on the protruded stigma 10 in the angle location part 9 to take place to rub with the ring gear 8 on the fixed cylinder 3 regularly, the local surfaces that causes rubbing with ring gear 8 on the protruded stigma 10 is easy to wearing and tearing, and the useful life of angle location part 9 is shorter.At this moment, when the user rotates described camera, can have some setbacks because of protruded stigma 10 increases feel to rotate with ring gear 8 frictions, even can't rotate camera again.
Second shortcoming is: because rotating cylindrical 4 and fixed cylinder 3 all are metalworks, so the cooperation between the two just must be the little matched in clearance of trying one's best, so that rotating cylindrical 4 energy are smooth and easy, rotation reposefully; But because the existence of chucking hook 17, make rotating cylindrical 4 fixed cylinder 3 of packing into is become very difficult.If strengthen the fit clearance between rotating cylindrical 4 and the fixed cylinder 3 fixed cylinder 3 so that rotating cylindrical 4 can easily be packed into, but chucking hook 17 be difficult to be pressed on the first axial block face 7, thereby make chucking hook 17 lose meaning.
Have, in the camera rotating shaft of practical application, the length of angle limits pin 11 is usually less than 3 millimeters again, and diameter is especially less than 1 millimeter.Produce so little device and be assembled on the rotating cylindrical 4 it all very difficult.This relatively poor production and assembly process process are unfavorable for the production in enormous quantities and the installation of described camera rotating shaft.
The shortcoming of above-mentioned camera rotating shaft parts directly causes the camera rotating shaft shorter useful life, and manufacturability is poor.

Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in detail.
The disclosed camera rotating shaft of the utility model comprises:
The fixed cylinder that comprises ring gear is fixedly mounted on the user terminal casing;
The rotating cylindrical 22 of elastic material, the one end is axially fixed in the fixed cylinder by the chucking hook of self, can rotate relatively with fixed cylinder; Its other end is installed with camera;
At least one angle location part 18, embedded being installed on the rotating cylindrical 22; Ring gear on its outstanding knuckling 20 and the fixed cylinder matches, and is used to make rotating cylindrical 22 to keep relative fixed with fixed cylinder.
In order to solve described camera rotating shaft short problem in useful life, can carry out as the improvement among Fig. 5 A described camera rotating shaft earlier, Fig. 5 A is an angle location part front view of the present utility model.As known in the figure, new angle location part 18 comprises keeper housing 19 and knuckling 20, and knuckling 20 can move up and down by relative positioning spare housing 19, can also rotate arbitrarily in keeper housing 19.
Referring to Fig. 5 B, Fig. 5 B is an angle location part broken section front view of the present utility model.This figure is the same with Fig. 5 A, all is the front view of angle location part 18, just among Fig. 5 B the first half of keeper housing 19 has been carried out analysing and observe processing.As seen, in keeper housing 19, be provided with spring 21, be used for knuckling 20 is applied the thrust of certain intensity, a part of spheroid of knuckling 20 can be emerging in outside the keeper housing 19.Certainly, the opening diameter on keeper housing 19 tops is less than the diameter of knuckling 20, to guarantee that knuckling 20 can not eject from keeper housing 19.
By the above as seen, when knuckling 20 rotations, its rotational trajectory is random.
Angle keeper 18 is being carried out the above-mentioned improved while, also will improve the manufacturability of described camera rotating shaft.Can both obtain embodying in Fig. 6 to the effect that improvement produced of angle keeper 18 and to the technological improvement of described camera rotating shaft, Fig. 6 is a camera rotating shaft partial cross-sectional perspective view of the present utility model.
Among Fig. 6, fixed cylinder 3 still is installed in the described user terminal casing, and the two does not promptly move to axial, and does not relatively rotate yet.One end of new rotating cylindrical 22 is installed in the fixed cylinder 3, and the other end still fixedly mounts with described camera.Rotating cylindrical 22 is an elastic component, and its material can be plastics, plastic cement, industrial reinforcing rubber etc.; In actual applications, fixed cylinder 3 also can be elastic components such as plastics, plastic cement, industrial reinforcing rubber, as long as guarantee that this elastic component is not yielding.
Rotating cylindrical 22 is provided with projection 23, then is provided with the first step-like chucking hook 24 on the projection 23.First chucking hook 24 compresses mutually with the first axial block face 7 on the fixed cylinder 3, make fixed cylinder 3 and rotating cylindrical 22 each other can't be axially away from; Equally, rotating cylindrical 22 is provided with projection 26, then is provided with the second step-like chucking hook 27 on the projection 26.Second chucking hook 27 compresses mutually with the first axial block face 7 on the fixed cylinder 3, make fixed cylinder 3 and rotating cylindrical 22 each other can't be axially away from.
Technically, as long as be provided with at least two chucking hooks on the rotating cylindrical 22, and a projection in the projection at these two chucking hooks difference places when 3 rotations of rotating cylindrical 22 relative fixed cylinders, can be blocked by the first rotation block face 5 and the second rotation block face 6.
In fact, can be provided with one or more projections that comprise chucking hook again, and the first axial block face 7 on this chucking hook and the fixed cylinder 3 is compressed mutually at rotating cylindrical 22, make fixed cylinder 3 and rotating cylindrical 22 each other can't be axially away from.
Certainly, no matter rotating cylindrical 22 is provided with several projections, preferably only makes one of them projection when 3 rotations of rotating cylindrical 22 relative fixed cylinders, can be blocked by the first rotation block face 5 and the second rotation block face 6.This situation shows as in Fig. 6: rotating cylindrical 22 when rotated, a projection in projection 23 or the projection 26 can by first the rotation block face 5 and second the rotation block face 6 block.
So do is because if two even plural described projection can both be blocked by the first rotation block face 5 and the second rotation block face 6, rotating cylindrical 22 relative fixed cylinders 3 revolvable angles will be very limited so, and then make the anglec of rotation that is fixedly mounted on the described camera on the rotating cylindrical 22 be subjected to unnecessary restriction.
In fact, also can make these projections when 3 rotations of rotating cylindrical 22 relative fixed cylinders, all can not blocked by the first rotation block face 5 and the second rotation block face 6 by the described projection on the rotating cylindrical 22 is provided with.So just make the anglec of rotation of rotating cylindrical 22 relative fixed cylinders 3 unrestricted, and then make the anglec of rotation that is fixedly mounted on the described camera on the rotating cylindrical 22 unrestricted.
Have, the face 25 of axially being close on axial block face 14 of second on the fixed cylinder 3 and the rotating cylindrical 22 compresses mutually, makes rotating cylindrical 22 further to move axially to fixed cylinder 3 inside again.
Like this, rotating cylindrical 22 just can keep axial restraint with fixed cylinder 3.
When fixed cylinder 3 and rotating cylindrical 22 are assembled, because rotating cylindrical 22 is elastic components, so can directly rotating cylindrical 22 levels be put in fixed cylinder 3.
When first chucking hook 24 and second chucking hook 27 push up on the second axial block face 14, only need continue to apply the thrust of certain intensity to rotating cylindrical 22, first chucking hook 24 and second chucking hook 27 will be because of being elastic component and to the distortion of the axle center of rotating cylindrical 22, and finally probe in the fixed cylinder 3, make that the second axial block face 14 on the fixed cylinder 3 compresses mutually with the face 25 of axially being close on the rotating cylindrical 22.
At this moment, because first chucking hook 24 and second chucking hook 27 have probeed in the fixed cylinder 3 fully, no longer be subjected to pointing to the pressure in the axle center of rotating cylindrical 22, so first chucking hook 24 and second chucking hook 27 all can restore to the original state because of self elasticity, and the first axial block face 7 on final and the fixed cylinder 3 compresses mutually.
Like this, rotating cylindrical 22 just can keep axial restraint with fixed cylinder 3.
Because first chucking hook 24 and second chucking hook 27 have elasticity, so can design these two chucking hooks bigger respectively than the chucking hook among Fig. 4 17, make first chucking hook 24 and second chucking hook 27 can be more securely with fixed cylinder 3 on the first axial block face 7 compress mutually, and can be uneasily landing from the first axial block face 7.
Having, because rotating cylindrical 22 has elasticity, so cooperating between rotating cylindrical 22 and the fixed cylinder 3 promptly can be matched in clearance, also can be interference fit again.
As seen, the aforesaid rotating cylindrical 4 of comparing no longer needs setting angle banking pin 11 on the rotating cylindrical 22, make rotating cylindrical 22 have better production technology; And when fixed cylinder 3 and rotating cylindrical 22 were assembled, rotating cylindrical 22 obviously had better assembly process process, and then makes described camera rotating shaft have better assembly process process.
In embedded mode one, two or more angle location part 18 are installed on the rotating cylindrical 22, outstanding knuckling 20 is arranged in angle location part 18, knuckling 20 matches with ring gear 8 on the fixed cylinder 3, that is: knuckling 20 can be absorbed in the mark of mouth between any two adjacent internal tooths on the ring gear 8.When rotating cylindrical 22 rotates in fixed cylinder 3, knuckling 20 can be absorbed in the mark of mouth between any two adjacent internal tooths on the ring gear 8, make rotating cylindrical 22 when the rotation external force that is not subjected to from the user, can keep relative fixed with fixed cylinder 3 because of knuckling 20 has been absorbed in the described mark of mouth, can rotation voluntarily on fixed cylinder 3.
Like this, after described camera that the user will be fixedlyed connected with rotating cylindrical 22 rotates to its required angle, just can unclamp hand relievedly, rotating cylindrical 22 natures can be in its present located anglec of rotation, and can not rotate voluntarily, make described camera can be in its present located anglec of rotation naturally, and can not rotate voluntarily.
Because knuckling 20 can rotate arbitrarily in keeper housing 19, and the rotational trajectory of knuckling 20 is random.So the whole outer surface of spheroid on the knuckling 20 all has an opportunity to contact with ring gear 8.As seen, it is more much bigger than the area that bears frictional force on the aforesaid protruded stigma 10 to bear the area of frictional force on the knuckling 20.
Have again, because knuckling 20 can roll, so its frictional force of being born when contacting with ring gear 8 is force of rolling friction; And protruded stigma 10 can't roll, so its frictional force of being born when contacting with ring gear 8 is force of sliding friction, and force of rolling friction is 1/30 of a force of sliding friction under the same terms.
As seen by above-mentioned, the protruded stigma 10 of comparing, knuckling 20 rate of wear in actual applications will be very slow, and this makes that obviously prolonged the useful life of angle location part 18, and then has directly prolonged the useful life of described camera rotating shaft.
By the above as can be seen, camera rotating shaft provided by the utility model has long useful life, has better manufacturability.
