Embodiment 1

[0076] figure 1 It is an enlarged schematic view of the tilt hinge of the present invention, the electronic dictionary 2 and the tilt hinge 1 disposed in the area A in one embodiment. The electronic dictionary 2 comprises a first casing 21 provided with a keyboard portion 21a and a second casing 22 provided with a display device 22a on the upper surface constituting the device body, wherein the tilt hinge 1 of the present invention supports the first casing The body 21 and the second housing 22 are hinges for opening and closing that can be opened and closed mutually. In this embodiment, the column 11 of the tilt hinge 1 is fixed on the hinge assembly part 211 of the first casing 21 of the electronic dictionary 2, and the flange element 124 of the tilt hinge 1 is fixed to the second casing 22 The hinge assembly part 221 of the electronic dictionary 2 can make the first casing 21 and the second casing 22 of the electronic dictionary 2 open and close. In addition, the cylinder...

Embodiment 2

[0097] Figure 7 It is a sectional view along the central axis of other embodiments of the tilting hinge of the present invention. In the tilting hinge 1A of Embodiment 2, the flange element 124 is provided with a raised portion 124a embedded in the cylinder 11 to prevent the cylinder 11 from The axial center overflows when the flange element 124 rotates relative to it. The other constituent elements are the same as those in Embodiment 1, and the same element numbers are given to the same elements.

Embodiment 3

[0099] Figure 8 It is a diagram of another embodiment of the present invention. In Embodiment 1, the hinge rod 12 and the flange element 124 are integrally formed, but in the tilt hinge 1B of Embodiment 3, the hinge rod 120 is a part of the flange element 1240. An independent constituent element. In other words, by forming, for example, a deformed shaft portion 1243 with a slightly elliptical cross-section on one side of the flange member 1240 of the hinge rod 120, and inserting the deformed shaft portion 1243 into the deformed assembly hole 1244 provided on the flange member 1240, and then tightly The fastening portion 1245 formed at the fixed exposed end can fix the hinge rod 120 on the flange element 1240 . Similarly, the other end of the hinge rod 120 can keep the bottom 112 of the cylinder 11 in a rotatable state as mentioned in the previous embodiment, when the friction pad 150 is used as the fastening portion 1246 .

Abstract

A slant hinge includes a cylindrical body, a flange element, a hinge rod, and a friction cam gear. The cylindrical body is arranged in either of a first housing and a second housing which can be opened and closed with each other. The cylindrical body is provided with a bottom which is small in diameter and is short in length. The flange element is arranged on an open end of the cylindrical body, and is arranged in the other housing. The hinge rod is arranged along the central axis direction of the cylindrical body and is fixed on either of the cylindrical body or the flange element, so the hinge rod can be pivotedly supported to rotate to another direction. The friction cam gear has the friction function and the adsorption function and is provided with a first cam, a cam element, and an elastic element. An electronic device which possesses the slant hinge is also disclosed.

Description

technical field [0001] The present invention relates to making the device body of the first casing and the display device of the second casing open and close mutually in small electronic devices such as mobile phones, electronic dictionaries, notebook computers, PDA (personal data assistant) or car navigation devices. A connected inclined hinge and an electronic device with the inclined hinge. Background technique [0002] As in the aforementioned small electronic devices such as mobile phones, electronic dictionaries, notebook computers, PDAs, and car navigation devices, the display device of the second housing can be opened and closed with the device body of the first housing through an opening and closing device. close. And this opening and closing device has the inclined hinge that can make the display device remain stationary at any angle with respect to the device body. [0003] Tilt hinges of the aforementioned nature are described in Patent Documents 1 to 3 listed ...
