In the engaging slot 313 in driven surface 311.One end of driven member 30 supports the end face of shrapnel 35.Snap ring 70 abuts holder 60
Second end face 612, so that hinge arrangement 100 is formed as an entirety.By the fixed part 13 and laptop of main shaft 10
200 lid 204 is connected, and the mounting portion 63 of holder 60 is connected with the ontology 202 of laptop 200, that is, installs.
The lid 204 of laptop 200 can be opened and closed relative to ontology 202 under external force, i.e., lid 204 passes through master
Axis 10 with dynamic friction piece 20 relative to driven member 30 rotate, make the fin 231 on friction member 20 skid off on driven member 30 it is corresponding from
Dynamic slot 315 simultaneously crosses neighbouring driven item 313, to be caught in another driven slot 315.When cancelling external force, fin 231 blocks
Entering makes lid 204 be positioned at a certain angle relative to ontology 202 in corresponding driven slot 315.
Due to thering are multiple fins 231, driven member 30 to be equipped with multiple driven slots 315, thus each fin on friction member 20
231 can be positioned in multiple driven slots 315, and then position rotation angle of the lid 204 relative to ontology 202 so that collapsible
The use of electronic device 200 is more convenient.
Hinge arrangement 100 controls 204 opening angle of lid by friction member 20, driven member 30, shrapnel 35 and gasket 40
The torque size of degree.The rubbing surface 23 of friction member 20 and the driven surface 311 of driven member 30 are spherical surface, and have driven item 313
And driven slot 315 can not increase hinge arrangement so that the contact area between rubbing surface 23 and driven surface 311 is larger
Frictional force is effectively improved in the case of 100 35 elastic force of appearance and size and shrapnel, and then improves moment of friction, and makes lid
204 firm rest in predetermined angle.And friction member 20 and the alloying component of driven member 30 can make friction member 20 and driven member 30
It is more resistant, it is hardly damaged.
Due to being provided with telescopic gauffer portion 1131 on main shaft 10, main shaft 10 wears collapsible drive snap ring after holder 60
70 push against holder 60 so that the installation of hinge arrangement 100 is more convenient.In addition, the shell 113 of main shaft 10 accommodates honeycomb Wiring body
115, based on cable in 202 provide receiving space, be convenient for the wiring of folding-type electronic device 200.And honeycomb connects up
Body 115 can support cable and absorb the heat of cable using lubrication honey.

Referring to Fig. 10, for example, multiple positioning strips 831 ' on locating piece 80 ' are not equally distributed, but formed
There are compact district 835 and ravel area 837.Only have 1 or a few servo-actuated item on follower.
Since consumer is opposite with multiple usual orientation angles, such as lid 204 when opening folding device 200
Ontology 202 is positioned at 90 degree of angular positions or the positions such as 120 degree of angles.When consumer's detachable cover 204, lid 204 is logical
When crossing main shaft 10 the servo-actuated item 93 of follower 90 being driven to slide into the compact district 835 of positioning strip 831 ', 204 opposing body of lid at this time
202 near an angle of 90 degrees, and the sliding by follower 93 at compact district 835 so that consumer 90 degree of angles more
Angle adjustment easily is carried out to lid 204.For example, the positioning strip 831 ' of ravel area 837 is 3, the positioning strip of compact district 835
831 ' be 3.Angle between 837 two neighboring positioning strip 831 ' of ravel area is 85 degree.The positioning strip 831 ' of ravel area 837
Height gradually increases along the radially outward direction of locating piece 80 ', and the height of the positioning strip 831 ' of compact district 835 is along locating piece
80 ' radially outward direction is gradually reduced, and can be made in this way, and it is more easy that servo-actuated item 93 is slided in ravel area 837, and in close
Slide more difficult, raising positioning accuracy in collection area 835.
For example, the folding-type electronic device of the present invention, if the other embodiment of display device further includes above-mentioned each implementation
The intercombination of mode is formed by display device.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each piece of technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
