Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

Referring to fig. 1 to 13, a lifting and overturning structure 100 according to an embodiment of the present invention is described, wherein the lifting and overturning structure 100 includes a fixing base 10, a lifting base 20, a stopper 40, and an overturning mechanism 60. It should be noted that the lifting and overturning structure 100 is used for driving the to-be-lifted and overturning member 110 to lift and overturn. The following description will take the lifting and turning structure 100 applied to the electronic device 200, and the member to be lifted and turned 110 as a camera module as an example.

As shown in fig. 1 to 13, the fixed base 10 is provided with a rotating member 30 that rotates in a first direction (e.g., the up-down direction shown in fig. 1) as an axial direction; the outer circumference of the rotation member 30 is provided with a first spiral track 31 and a second spiral track 32 spirally extending in the first direction. The lifting base 20 is movably disposed relative to the fixed base 10 along the first direction, the turning member 110 to be lifted is disposed on the lifting base 20, and the lifting base 20 is provided with a first mating member 21 that is engaged with the first spiral track 31 for limiting, so that when the rotating member 30 rotates, the lifting base 20 is driven to lift along the first direction by the engagement between the first mating member 21 and the first spiral track 31. Therefore, when the lifting base 20 is lifted along the first direction, the turnover part 110 to be lifted can move along the lifting base 20 along the first direction.

As shown in fig. 2, the stopping member 40 is movably disposed relative to the fixed base 10 along the first direction, and the stopping member 40 is provided with a second mating member 41 that is engaged with the second spiral track 32 for limiting, so that when the rotating member 30 rotates, the stopping member 40 is driven to move up and down along the first direction by the engagement between the second mating member 41 and the second spiral track 32. For example, the first engaging member 21 is integrally formed with the lifting base 20, and the second engaging member 41 is integrally formed with the stopper 40.

As shown in fig. 12, the first spiral track 31 includes a first sub-track 311 and a second sub-track 312, the second spiral track 32 includes a third sub-track 321 and a fourth sub-track 322, the first sub-track 311 and the third sub-track 321 are disposed at equal intervals, when the first sub-track 311 and the first mating member 21 are mated, the third sub-track 321 and the second mating member 41 are mated, and at this time, the stopper 40 and the to-be-lifted and inverted member 110 are abutted. The distance between the second sub-rail 312 and the fourth sub-rail 322 is gradually decreased, and when the second sub-rail 312 is engaged with the first engaging element 21, the fourth sub-rail 322 is engaged with the second engaging element 41, and at this time, the stopper 40 is disengaged from the member to be turned 110. It should be noted that when the lifting and turning member 110 is lifted and turned, the first engaging member 21 will continue to engage with the second sub-rail 312 after engaging with the first sub-rail 311, and the second engaging member 41 will continue to engage with the fourth sub-rail 322 after engaging with the third sub-rail 321; when the lifting/lowering/turning member 110 descends and turns reversely, the first engaging member 21 is engaged with the second sub-rail 312 and then continuously engaged with the first sub-rail 311; after the second engaging element 41 engages with the fourth sub-track 322, it will continue to engage with the third sub-track 321.

The turnover mechanism 60 is used for driving the turnover part 110 to be lifted and fallen to turn over; when the second matching element 41 is matched with the third sub-rail 321, the stopping element 40 abuts against the to-be-lifted and inverted element 110 to limit the rotation thereof, and when the second matching element 41 is matched with the fourth sub-rail 322, the stopping element 40 is separated from the to-be-lifted and inverted element 110 to enable the overturning mechanism 60 to drive the to-be-lifted and inverted element 110 to overturn. Through the arrangement of the turnover mechanism 60, the rotation and the reset of the turnover part 110 to be lifted can be realized conveniently.

For example, when the member to be lifted and lowered 110 is not needed to operate, at this time, the member to be lifted and lowered 110 may be located inside the electronic device 200, and may not occupy the space of the screen of the electronic device 200, so as to improve the space occupation ratio of the screen of the electronic device 200. When the user needs to use the camera function, the rotating component 30 rotates, and the stopper abuts against the to-be-lifted and inverted component, the first mating component 21 is lifted up in the upper direction of fig. 1, for example, under the restriction of the first spiral track 31 of the rotating component 30, so that the to-be-lifted and inverted component 110 can extend to the outside of the electronic device 200, and at this time, the second mating component 41 is lifted up in the upper direction of fig. 1, for example, under the restriction of the second spiral track 32 of the rotating component 30, so as to ensure that the stopper 40 abuts against the to-be-lifted and inverted component 110. It should be noted that the rotating member 30 can rotate in the opposite direction, and at this time, the member to be lifted 110 can be lowered and turned in the opposite direction, for example, in the lower direction of fig. 1. When the stop member 40 is disengaged from the to-be-lifted and inverted member 110, the to-be-lifted and inverted member 110 may be inverted to change the direction, so that the user can conveniently take a picture.

Among the correlation technique, treat two actions of lift and the upset of lift upset piece, can't drive the realization through same part, consequently need set up respectively and be used for driving the part of treating the lift action of lift upset piece to and be used for driving the upset action part of treating lift upset piece, can lead to like this that the structure of lift flip structure is complicated, is unfavorable for its miniaturized design, and the dismouting is efficient simultaneously, and is with high costs. In the application, the rotating part 30 is arranged, so that the same rotating part 30 can control the lifting action and the overturning action of the to-be-lifted overturning part 110, the structure is simplified, the assembly efficiency is improved, the cost is reduced, the weight is reduced, and the miniaturization design of the lifting overturning structure 100 is facilitated.

According to the lifting and overturning structure 100 of the embodiment of the invention, the lifting and overturning structure 100 can drive the to-be-lifted and overturning member 110 to lift and overturn, so that the occupied space of the to-be-lifted and overturning member 110 is reduced. Through first fitting piece 21 and the cooperation of first spiral track 31, second fitting piece 41 and the cooperation of second spiral track 32, can change the rotation of rotating piece 30 into first fitting piece 21 effectively, the rectilinear motion of second fitting piece 41, can realize waiting to go up and down two actions of lift and upset of upset piece 110 through the rotation of rotating piece 30, the structure of lift flip structure 100 has been simplified, the assembly efficiency is improved, the cost is reduced, the weight of lift flip structure 200 has been reduced, be convenient for realize the miniaturized design of lift flip structure 100, the transmission efficiency is high.

In some embodiments, the rising amplitude of the fourth sub-track 322 is smaller than that of the second sub-track 312, so that when the second mating member 41 mates with the fourth sub-track 322, the rising speed of the stop member 40 is smaller than that of the to-be-lifted turnover member 110, so that the stop member 40 can be disengaged from the to-be-lifted turnover member 110, so that the turnover mechanism 60 can turn over. Of course, in other embodiments, referring to fig. 6, the fourth sub-track 322 extends along a direction perpendicular to the first direction, that is, at this time, the stopping member 40 may not rise any more, and at this time, the lifting base 20 drives the to-be-lifted and inverted member 110 to continue to rise, so that the stopping member 40 is separated from the to-be-lifted and inverted member 110, and the to-be-lifted and inverted member 110 can be inverted.

It should be noted that, after the to-be-lifted turnover member 110 is turned over by a preset angle, the to-be-lifted turnover member 110 may be again abutted against the stopper member 40, so as to ensure that the to-be-lifted turnover member 110 is turned over by a preset angle of, for example, 90 ° and then stopped, thereby improving the function of the stopper member 40, ensuring that the to-be-lifted turnover member 110 has a simple structure, facilitating assembly and facilitating miniaturization design. Meanwhile, the second spiral track 32 designed in this way is ingenious in design, and different moving distances between the stopper 40 and the lifting base 20 can be realized without arranging other structures, so that the member to be turned 110 is separated from the stopper 40, and the structure of the member to be turned 110 is simplified.

In the example shown in fig. 2, the first fitting piece 21 and the second fitting piece 41 may be of a cylindrical structure, the first spiral track 31 and the second spiral track 32 are grooves, the first fitting piece 21 and the first spiral track 31 are in snap fit, and the second fitting piece 41 and the second spiral track 32 are in snap fit, so that the manner of snap fit is simple and reliable, and the installation efficiency is high. In other embodiments, the first mating member 21 and the second mating member 41 may be grooves, the first spiral track 31 and the second spiral track 32 both protrude from the outer circumference of the rotating member 30, the first mating member 21 and the first spiral track 31 are snap-fit, and the second mating member 41 and the second spiral track 32 are snap-fit. That is, the second spiral track 32 and the first spiral track 31 may have the same structure, and the second fitting member 41 may have the same structure as the first fitting member 21. Therefore, on the one hand, the processing can be facilitated; on the other hand, it is convenient to ensure the synchronous ascent of the stopper 40 and the flipper 110 to be raised and lowered.

In some embodiments, as shown in fig. 3 and 5, the to-be-lifted and inverted member 110 may include a module main body 111, the lifting base 20 has an open opening 22, the module main body 111 is adapted to be received in the open opening 22, and when the stopper 40 is separated from the to-be-lifted and inverted member 110, a portion of the module main body 111 is located outside the open opening 22. The lifting base 20 thus provided can improve the mounting stability of the module main body 111, and ensure the reliability of the mounting of the module main body 111 extending out of the electronic device 200. And at the same time, can play a role in protecting the module main body 111.

Further, as shown in fig. 3, the lifting and overturning structure 100 further includes a first rotating shaft 112, and the first rotating shaft 112 is disposed at one end of the module main body 111 facing the stopper 40. One end of the first rotating shaft 112 is connected to one end of the module main body 111, and the other end of the first rotating shaft 112 is adapted to be abutted against the stopper 40. For example, the lifting base 20 may have a first through hole 23, and one end of the first rotating shaft 112 may be inserted through the first through hole 23. Therefore, the reliability of the installation of the to-be-lifted turnover part 110 can be improved, and meanwhile, the arrangement of the first rotating shaft 112 can provide rotating support for the turnover of the module main body 111, so that the module main body 111 can be turned over by taking the first rotating shaft 112 as a fulcrum, and the reliability of the turnover of the module main body 111 is ensured. As shown in fig. 6, a stepped portion 1121 is formed at the other end of the first rotating shaft 112, and the stepped portion 1121 is used for abutting against the stopper 40. Thereby, the reliability of the stop of the stopper 40 against the turnover member 110 to be lifted and lowered can be improved.

Referring to fig. 7, at this time, the stopping member 40 abuts against the to-be-lifted and inverted member 110, the step portion 1121 is located at the front end as shown in fig. 7, when the stopping member 40 is separated from the to-be-lifted and inverted member 110, the to-be-lifted and inverted member 110 is inverted counterclockwise as shown by the dotted line in fig. 7, and in combination with fig. 9, the inverted to-be-lifted and inverted member 110 abuts against the stopping member again. As shown in fig. 13, at this time, the stopping member 40 abuts against the to-be-lifted and inverted member 110, the step portion 1121 is located at the rear end as shown in fig. 13, and when the stopping member 40 is separated from the to-be-lifted and inverted member 110, and the to-be-lifted and inverted member 110 is turned clockwise as shown by the dotted line in fig. 13, the to-be-lifted and inverted member 110 may abut against the stopping member again.

For example, the turnover mechanism 60 may be a slider-crank structure. In this case, the stopper 40 may be equivalent to a slider, the turnover mechanism 110 to be lifted is equivalent to a rotatable structure, and the turnover mechanism 60 may be equivalent to a crank, so that the turnover mechanism 110 to be lifted can control the rotation angle of the turnover mechanism 60. Alternatively, canting mechanism 60 may be a torsion spring. Through setting up the predetermined torsion angle of torsional spring, can control the rotation angle of waiting to lift upset 110 to specifically set up according to actual demand. The torsional spring occupies a small space, has a simple structure, is large in torsion and low in cost, can be convenient for control of the rotating range of the lifting turnover part 110, can be stopped at any preset position where the torsion spring needs to be stopped, is convenient for control of the rotating angle of the lifting turnover part 110, and can ensure the effectiveness of the back-and-forth turnover of the lifting turnover part 110.

In some embodiments, as shown in fig. 3, the lifting and overturning structure 100 further includes a second rotating shaft 113, the second rotating shaft 113 is connected to the other end of the module main body 111, the overturning mechanism 60 is sleeved on the second rotating shaft 113, for example, the lifting base 20 has a second through hole 24, and the second rotating shaft 113 is disposed through the second through hole 24. From this, can improve the reliability of treating the installation of lift upset piece 110, simultaneously, can provide the rotation support for the upset of module main part 111 for module main part 111 can use second rotation axis 113 to overturn as the fulcrum, in order to guarantee the reliability of module main part 111 upset. For example, the turning mechanism 60 of the torsion spring may be sleeved on the second rotating shaft 113 to ensure the reliability of the installation of the torsion spring and the torsion spring may effectively drive the turning member 110 to be lifted to turn. For example, the turnover part 110 to be lifted includes the first rotating shaft 112 and the second rotating shaft 113, which may be beneficial to ensure the balance and stability of the rotation of the turnover part 110 to be lifted.

In the example of fig. 6, the lift-tilt mechanism 100 may further include a third sliding rod 90, the third sliding rod 90 extends along the first direction, the third sliding rod 90 is mounted on the fixed base 10, and the lift base 20 is sleeved on the third sliding rod 90. Thus, the third slide lever 90 can ensure the smoothness of the lifting movement of the lifting base 20. Meanwhile, the function of limiting the lifting base 20 can be achieved.
