The application also provides an electronic device with the rotating shaft mechanism, and the thickness of the electronic device is reduced.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, an embodiment of the present application provides a rotating shaft mechanism, which includes a first rotating shaft 1, a second rotating shaft 2, and a transmission member 3; the first rotating shaft 1 and the second rotating shaft 2 are arranged approximately in parallel, the first rotating shaft 1 is provided with a first section part 11, and the outer peripheral surface of the first section part 11 is provided with a first spiral groove 111 which extends spirally around the axis of the first rotating shaft 1; the second rotating shaft 2 is provided with a second section part 21, the position of the second section part 21 corresponds to that of the first section part 11, and the outer peripheral surface of the second section part 21 is provided with a second spiral groove 211 spirally extending around the axis of the second rotating shaft 2; the transmission member 3 includes a main body 33, and a first guide 31 and a second guide 32 fixedly connected to the main body 33, wherein the first guide 31 is matched with the first spiral groove 111, the second guide 32 is matched with the second spiral groove 211, and the transmission member 3 enables the first rotating shaft 1 and the second rotating shaft 2 to synchronously rotate.
The working principle of the rotating shaft mechanism is as follows: the first rotating shaft 1 rotates, because the first guide member 31 of the transmission member 3 is matched with the first threaded groove 111, the first threaded groove 111 drives the first guide member 31 to move in the first threaded groove 111, and because the transmission member 3 is limited to rotate by the second rotating shaft 2, the first guide member 31 can only push the transmission member 3 to move along the axial direction of the first rotating shaft 1, so that power is transmitted from the first rotating shaft 1 to the transmission member 3; meanwhile, since the second guide member 32 is matched with the second threaded groove 211, when the transmission member 3 moves axially relative to the second rotating shaft 2 at the same time, the second guide member 32 moves in the second threaded groove 211, so as to drive the second rotating shaft 2 to rotate, thereby realizing the transmission of power from the transmission member 3 to the second rotating shaft 2, and realizing the synchronous rotation of the first rotating shaft 1 and the second rotating shaft 2.
It can be seen that, since the first spiral groove 111 and the second spiral groove 211 are respectively formed on the outer peripheral surfaces of the first section 11 of the first rotating shaft 1 and the second section 21 of the second rotating shaft 2, the sizes of the first rotating shaft 1 and the second rotating shaft 2 are not increased radially, after the first guide member 31 is matched with the first spiral groove 111, the first guide member 31 is usually embedded into the first spiral groove 111, and the second guide member 32 and the second spiral groove 211 are similar, compared with the existing rotating shaft which transmits power through a gear, the height of the whole rotating shaft mechanism is reduced.
In this embodiment, the first section 11 of the first rotating shaft 1 and the rest of the first rotating shaft 1 are integrally formed, or are separately assembled, and the integrally formed structure has high structural strength and is convenient to process and manufacture. Similarly, the second section 21 of the second rotating shaft 2 and the rest of the second rotating shaft 2 are integrally formed or separately assembled.
As shown in fig. 1 and 2, in the present embodiment, the rotation directions of the first spiral groove 111 and the second spiral groove 211 are opposite, for example, if the rotation direction of the first spiral groove 111 is left-handed, the rotation direction of the second spiral groove 211 is right-handed, or if the rotation direction of the first spiral groove 111 is right-handed, the rotation direction of the second spiral groove 211 is left-handed. Due to the fact that the rotation directions are opposite, the rotation directions of the first rotating shaft 1 and the second rotating shaft 2 are opposite, when the first rotating shaft 1 rotates forwards, meanwhile, the second rotating shaft 2 is driven to rotate backwards through the transmission piece 3, the rotating shaft mechanism is applied to electronic equipment, and synchronous relative overturning of a first object connected with the first rotating shaft 1 and a second object connected with the second rotating shaft 2 can be achieved.
Of course, the rotation directions of the first spiral groove 111 and the second spiral groove 211 may also be the same, and are the same as the left rotation or the right rotation, so that the rotation directions of the first rotating shaft 1 and the second rotating shaft 2 are the same, and the rotating shaft mechanism is applied to the electronic device, and can realize the synchronous rotation in the same direction of the first object connected with the first rotating shaft 1 and the second object connected with the second rotating shaft 2.
Further, in the present embodiment, the pitches of the first spiral groove 111 and the second spiral groove 211 are the same, so that the first rotating shaft 1 and the second rotating shaft 2 achieve synchronous constant-speed rotation after power is transmitted through the transmission member 3. Of course, the pitches of the first spiral groove 111 and the second spiral groove 211 may be different, and the unequal rotation of the first rotating shaft 1 and the second rotating shaft 2 is realized after the power is transmitted through the transmission member 3.
As shown in fig. 3, in the present embodiment, both sides of the main body 33 of the transmission member 3 are provided with concave mating surfaces for being respectively embedded with the outer peripheral surface of the first section 11 and the outer peripheral surface of the second section 21, the first guiding member 31 and the second guiding member 32 are respectively disposed in the concave mating surfaces of both sides of the main body 33, the main body 33 is disposed between the first rotating shaft 1 and the second rotating shaft 2, and the overall height of the rotating shaft mechanism is further reduced by the concave mating surfaces. Certainly, the main body 33 of the transmission member 3 can also be provided with two concave matching surfaces on the same side for being respectively embedded with the first rotating shaft 1 and the second rotating shaft 2, and the main body 33 is arranged on the same side of the first rotating shaft 1 and the second rotating shaft 2, so that the synchronous rotation of the first rotating shaft 1 and the second rotating shaft 2 can be realized, and the overall height of the rotating shaft mechanism is reduced relative to the power transmission of the gear.

Preferably, the mating surface between the first and second portions 331 and 332 is a curved surface to facilitate positioning in the height and horizontal directions. Of course, the first portion 331 and the second portion 332 may have different structures, and only can be used with the first rotating shaft 1 and the second rotating shaft 2, respectively, and accordingly, the first segment 11 and the second segment 21 are asymmetrically arranged.
