Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings 1-3 of the specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1, fig. 2 and fig. 3 together, an embodiment of the invention provides an electronic device 100, where the electronic device 100 includes a main body 10, a display screen 20 and at least one connection mechanism 30, and the connection mechanism 30 is connected between the main body 10 and the display screen 20.

The connecting mechanism 30 includes a hinge 40 and a holding mechanism 50, the hinge 40 is pivotally connected between the main body 10 and the display screen 20, so that the display screen 20 can rotate relative to the main body 10; the abutting mechanism 50 abuts between the main body 10 and the display screen 20 to increase the rotation torque of the display screen 20 and the main body 10.

As shown in fig. 2 and 3, the abutting mechanism 50 includes a fixing portion 51, an elastic portion 52 and an abutting rod 53, the fixing portion 51 is fixedly connected to the body 10, the elastic portion 52 is connected to the fixing portion 51, the abutting rod 53 includes a first end portion 531 and a second end portion 532 opposite to the first end portion 531, the first end portion 531 abuts against the elastic portion 52, the second end portion 532 abuts against one side of the display screen 20 close to the body 10, the elastic portion 52 is configured to provide an elastic force for the abutting rod 53 to press the display screen 20, so that a friction force between the abutting rod 53 and the display screen 20 is increased, and further a rotation torque between the display screen 20 and the body 10 is increased.

When the display screen is specifically assembled and used, an assembling worker can firstly select a hinge 40 with a lower torque to connect the body 10 with the display screen 20, at this time, because the torque of the hinge 40 is lower, the display screen 20 can rotate under the action of gravity, then select one of the abutting mechanisms 50, fix the fixing part 51 on the body 10, and enable one end of the abutting rod 53 to abut against the elastic part 52, and enable the other end to abut against the display screen 20. Since the supporting rod 53 supports against the elastic portion 52, the elastic portion 52 is elastically deformed, and the supporting rod 53 pushes the display screen 20, so that the friction between the supporting rod 53 and the display screen 20 is increased. Moreover, an assembler can adjust the friction between the support rod 53 and the display screen 20 by selecting the support rods 53 with different lengths, so as to obtain a proper torque between the display screen 20 and the body 10, so that the user does not lift the body 10 when opening the display screen 20, and the display screen 20 does not close automatically under the action of gravity.

In this embodiment, a supporting shaft 21 protrudes from a side of the display screen 20 close to the body 10, the supporting shaft 21 includes an axial direction O, and the supporting rod 53 contacts with the supporting shaft 21 along another direction perpendicular to the axial direction O.
