Enclose.
Fig. 1 is the schematic perspective view of electronic installation in this utility model one embodiment；Fig. 2 is the side-looking of Fig. 1 electronic installation
Schematic diagram.As depicted in figs. 1 and 2, this utility model discloses a kind of electronic installation 1, and it includes a first noumenon 10, one second
Body 20 and an electronic component 40.The first noumenon 10 and the second body 20 are connected to each other, and electronic component 40 can be arranged at
One body 10 or the second body 20.In the present embodiment, electronic component 40 is arranged at the first noumenon 10.For example, electronics dress
Putting 1 can be a notebook computer, and electronic component 40 is a screen, in other embodiments, the first noumenon 10 of electronic installation 1
It is a tablet PC, and the second body 20 is a base or an input platform.Furthermore, in the present embodiment and partial other
In embodiment, electronic installation 1 further includes an articulated part 30, for pivot joint the first noumenon 10 and the second body 20, so that first
Body 10 and the second body 20 can pivot with respect to articulated part 30 and have multiple positions.Wherein, the material of articulated part 30 can
To be metal, to strengthen the effect of fixation.
The first noumenon 10 includes one first housing 11 and multiple magnetic part 12, and magnetic part setting 12 is in the first housing 11
Interior, the first housing 11 has the first side 111 relative to each other and the 3rd side 113.For example, magnetic part 12 is a permanent magnetic
Ferrum.Additionally, the quantity of magnetic part 12 is not used for limiting this utility model in accompanying drawing, it arbitrarily can adjust according to design requirement.
Second body 20 includes one second housing 21, multiple magnetic sensor 22, multiple magnetic conductive part 23 and a switch control
Element 24 processed.Second housing 21 has the second side 212 relative to each other and the 4th side 214, the second side 212 of the second housing 21
Connect the first side 111 of the first housing 11 in relatively-movable mode.In the present embodiment, magnetic part 12 and articulated part 30 it
Between first be substantially equal to second distance d2 between magnetic sensor 22 and articulated part 30 apart from d1.So, the first housing
Spacing between 11 the first side 111 and the second side 212 of the second housing 21 keeps fixing, and the 3rd side of the first housing 11
113 and second the distance of the 4th side 214 of housing 21 change with the pivot between the first noumenon 10 and the second body 20.
Furthermore, magnetic sensor 22, magnetic conductive part 23 and switch control element 24 are all arranged in the second housing 21.Magnetic

Thus result can obtain it, and the external form for magnetic conductive part makees the effect that different designs still can reach magnetic force strengthening really
Really, the angular range of the especially bearing of trend of the bearing of trend of first edge segmentation and the 3rd edge segments is at 40 degree to 130
The magnetic conductive part (such as magnetic conductive part 23e) of the magnetic conductive part (such as magnetic conductive part 23b, 23c and 23d) of degree and half-circular cutouts has preferably
Magnetic force strengthening effect.
Although the male part (that is, male part 232a to 232e) in the embodiment of above-mentioned Fig. 5 a to Fig. 5 d and Fig. 6 is away from leading
The side of magnetic body an edge (that is, be made up of first edge segmentation s1a to the 3rd edge segments s3a edge 233a, by
Edge 233b that first edge segmentation s1b to the 3rd edge segments s3b forms, divided by first edge segmentation s1c to the 3rd edge
Edge 233c, the edge 233d being made up of first edge segmentation s1d to the 3rd edge segments s3d of section s3c composition and by the
The edge 233e that one edge segments s1e to the 3rd edge segments s3e forms) all there are three edge segments, but this practicality is new
Type is not limited to this embodiment.In this utility model, the edge of the side away from magnetic conduction body for the male part may be, for example, but
It is not limited to a circular arc or there is at least one knuckle.In addition, the shape of this male part can be symmetric shape or asymmetrically shaped.
In sum, except can by configuration magnetic conductive part expand in magnetic sensor and guide field in addition to, this practicality
New disclosed electronic installation more further by the design of magnetic conductive part is reached with the function of magnetic force strengthening, and then can increase
Magnetic sensor can distance of reaction and lifting magnetic sensor sensitivity.Even if consequently, it is possible to magnetic sensor and magnetic
Farther out, magnetic sensor still may detect that the magnetic field of magnetic part to the distance between property part.
