Abstract

The present disclosure provides a connecting device and an electronic apparatus having the same, which overcome the above deficiencies in related art, by using the connecting device, no matter where the rotating mechanism is rotated, the enclosing mechanism enclosing the outside of the rotating mechanism will always fit onto the rotating mechanism without any wrinkles or rig marks occur. A connecting device for rotatably connecting a first and a second bodies includes a rotating mechanism for rotationally connecting the first body and the second body together, wherein the connecting device further comprises an enclosing mechanism to enclose and cover at least a part of the rotating mechanism. The enclosing mechanism is attached to the first body and the second body respectively, and the degree of tightness of the enclosing mechanism varyies with the rotation of the rotating mechanism.

First claim

1 . A connecting device for rotatably connecting a first body and a second body, the connecting device comprising:
a rotating mechanism configured to rotatably connect the first body and the second body together; and an enclosing mechanism configured to enclose and cover at least a part of the rotating mechanism, the enclosing mechanism being attached to the first body and the second body respectively, and the degree of tightness of the enclosing mechanism varying with the rotation of the rotating mechanism.

2 . The connecting device according to claim 1 , wherein the enclosing mechanism comprises a first enclosing piece enclosing a first side of the rotating mechanism, and with the rotation of the rotating mechanism, the connecting device has a first state in which the first side of the rotating mechanism is located within the intersection angle between the first body and the second body, and a second state in which the first side of the rotating mechanism is located out of the intersection angle between the first body and the second body.

3 . The connecting device according to claim 2 , wherein when the connecting device is in the first state, the first enclosing piece has a first tightness degree, and when the connecting device is in the second state, the first enclosing piece has a second tightness degree, the first tightness degree being looser than the second tightness degree.

4 . The connecting device according to claim 2 , wherein the enclosing mechanism further comprises a second enclosing piece enclosing a second side of the rotating mechanism, the second side being arranged opposite to the first side, and when the connecting device is in the first state, the second side is located out of the intersection angle between the first body and the second body, and when the connecting device is in the second state, the second side is located within the intersection angle between the first body and the second bodies.

5 . The connecting device according to claim 4 , wherein when the connecting device is in the first state, the second enclosing piece has a third tightness degree, and when the connecting device is in the second state, the second enclosing piece has a fourth tightness degree, the third tightness degree being tighter than the fourth tightness degree.

6 . The connecting device according to claim 1 , wherein the enclosing mechanism is prestretched to have a preset tightness degree before the enclosing mechanism is attached to the first body and second body.

7 . The connecting device according to claim 1 , wherein the material for the enclosing mechanism is silica gel.

8 . The connecting device according to claim 1 , wherein the connecting device further comprises a cover to attach the enclosing mechanism onto the first body and the second body, the enclosing mechanism is implemented with two pockets, the opposite end faces thereof being open, the enclosing mechanism fitting over the outer side of the rotating mechanism, and there are two covers each implemented with two cuboids, the opposite end faces thereof being open, the two covers are fitted over the outer side of the two open ends of the enclosing mechanism; the covers, the enclosing mechanism and the rotating mechanism are provided with corresponding screw holes and the enclosing mechanism and the rotating mechanism are attached together by threading screws into the screw holes.

9 . The connecting device according to claim 8 , wherein the inner side of the cover is provided with raised strips extending along its entire longitudinal direction; or the outer side of the enclosing mechanism is provided with raised strips extending along its entire longitudinal direction, and the inner side of the cover is provided with recess cooperating with the raised strips, and/or the outer side of the enclosing mechanism is provided with a recess extending along its entire longitudinal direction and the inner side of the cover is provided with raised strips cooperating with the recess; the raised strips and/or the recess are used to press the enclosing mechanism onto the rotating mechanism while forcing the enclosing mechanism evenly.

10 . The connecting device according to claim 8 , wherein the rotating mechanism is a multi-spindle rotating mechanism having a plurality of connection taps protruding outward in the radial direction of the spindles, the screw holes of the rotating mechanism are provided on the connection taps, and the connection taps of the rotating mechanism are also used for connecting the first body and the second body in addition to connecting the rotating mechanism to the enclosing mechanism and the covers, in such a way that the enclosing mechanism is attached to the first body and the second body.

11 . The connecting device according to claim 1 , wherein the rotating mechanism comprises:
