The first connector 322 is connected to the main body 10, and the second connector 323 is connected to the display 20.
Optionally, a first socket c1 is provided on a side of the display screen 20 facing the hinge module 30. The side of the main body 10 facing the hinge module 30 is provided with a second insertion groove. The first plug part 331 is plugged in the first plugging groove c1, and the second plug part 332 is plugged in the second plugging groove.
Alternatively, the first hinge 31, the first plug part 331 and the second plug part 332 are integrally formed, and may also be fixedly connected by a mechanical connection.
Alternatively, the first hinge 31 includes a plurality of rod bodies 311 and a plurality of connecting parts 312. A connecting portion 312 is connected between two adjacent rods 311. The thickness of the connecting portion 312 is smaller than that of the rod body 311. The accommodation space rn penetrates the rod body 311 and the connecting portion 312.
The connection portion 312 is used to connect the rod 311, so that the first hinge 31 can be bent. Because the thickness of the connecting portion 312 is smaller than that of the rod body 311, a space is formed between the rod bodies 311, which is convenient for bending.
In addition, the receiving space rn penetrates the rod body 311 and the connection portion 312, so that the flexible circuit board 321 is protected.
Optionally, the rod 311 and the connecting portion 312 are integrally formed, so that the first hinge 31 is modularized, and the connection stability is improved.
Optionally, referring to fig. 7, the plurality of rods 311 includes a first rod 31a and a second rod 31 b. The first stick 31a is close to the display 20, and the second stick 31b is close to the host 10.
When the first hinge 31 is in the bent state, the radian of the first rod 31a is larger than that of the second rod 31 b. That is, the central angle of the first rod 31a is larger than the central angle of the second rod 31 b.
The radian of the first rod 31a is larger than that of the second rod 31b, so that the display screen 20 is in an upright state when the display device 100 is in an unfolded state.
Optionally, the display device 100 has a dummy bending axis O. The first hinge 31 is intended to be bent around a bending axis O.
The arc length hc of the first rod 31a increases progressively from the side close to the bending axis O to the side far from the bending axis O. Such an arrangement facilitates the bending of the first hinge 31 and reduces the bending radius. The gradual arrangement of the first rod 31a makes the cooperation between the first rod 31a and the second rod 31b smooth.
Optionally, the second lever 31b includes a first portion 3b1 and a second portion 3b 2. In the thickness direction, the first portion 3b1 is connected to the second portion 3b 2. The width of the first section 3b1 is greater than the width of the second section 3b 2. The connecting portion 312 is connected between two adjacent first portions 3b 1.
The width of the first portion 3b1 is greater than that of the second portion 3b2, so that when the first hinge 31 is bent, the second portion 3b2 abuts against the narrow end of the first rod 31a to form a short bending radius; when the first hinge 31 is unfolded, the first portion 3b1 abuts against the wide end of the first lever 31a, so that the display screen 20 can be quickly opened.
Alternatively, the width of the second portion 3b2 decreases from the side connected with the first portion 3b1 to the side away from the first portion 3b1 in the second portion 3b 2. The gradual arrangement of the second portion 3b2 allows the first hinge 31 to bend and unfold smoothly.
Optionally, a groove ac communicated with the accommodating space rn is further disposed in the second rod 31 b. The groove ac is disposed on the side of the second rod 31b close to the second portion 3b2, so that the flexibility of the second portion 3b2 is improved, the bending performance of the first hinge 31 is improved, and the support of the first portion 3b1 is ensured to better support the display screen 20.
Optionally, referring to fig. 8 and 9, the display screen 20 includes a first frame 21, a second frame 22, a second hinge 23, and a flexible panel 24.
The first frame 21 is detachably connected to the hinge module 30. The first frame 21 is provided with a first groove ca 1. The second frame 22 is located at one side of the first frame 21. The second frame 22 is provided with a second groove ca 2.
The second hinge 23 is connected between the first frame 21 and the second frame 22. The flexible panel 24 is disposed within the first and second slots ca1, ca2 and on the second hinge 23.
When the display screen 20 is in the unfolded state, the center of gravity of the display screen 20 is located on a side of the first frame 21 close to the hinge module 30.
The display device 100 of the embodiment shifts the center of gravity of the display screen 20, so that the center of gravity of the display screen 20 is shifted downward, which is convenient for holding; when the display screen 20 is connected with the host computer 10, the center of gravity is deviated downwards, the whole structure is more stable, the whole machine is not easy to topple, and the reliability is higher.
Alternatively, in the first frame 21, the weight of the first frame 21 decreases from the side close to the hinge module 30 to the side away from the hinge module 30.
In the second frame 22, the second hinge 23 is located on the side away from the second hinge 23. The weight of the second frame 22 decreases.
The part of the first frame 21 and the part of the second frame 22 adopt a weight gradual change mode, so that the stability of the whole machine is higher and the reliability is better.
Optionally, a battery, a circuit board, etc. may be disposed at the lower portion of the first frame 21 to increase the weight.
In some embodiments, the portion of the first frame 21 and the portion of the second frame 22 may also be non-weight-graded, such as by providing a weight module to achieve a shift in the center of gravity.
Alternatively, in the first frame 21, the thickness of the first frame 21 decreases from the side close to the hinge module 30 to the side away from the hinge module 30.
In the second frame 22, the thickness of the second frame 22 decreases from the side close to the second hinge 23 to the side away from the second hinge 23.
The shift of the center of gravity is achieved by a gradual change in thickness. The portion with the larger thickness can be provided with more electronic devices for more weight.
In some embodiments, the center of gravity may not be shifted by a gradual thickness change.
