The two third limiting parts 433 are arranged at the two opposite ends of the third rotating shaft 431, the area of the cross section of the third limiting part 433 perpendicular to the axial direction of the third rotating shaft 431 is larger than the area of the first through hole and the area of the second through hole, the third rotating shaft 431 can be limited through the two third limiting parts 433, and the third rotating shaft 431 is prevented from falling out of the first through hole and the second through hole.
The third elastic member 432 may be disposed between the two third limiting parts 433, and the third elastic member 432 may be compressed to increase a friction force between the third limiting parts 433 and the second portion 4a, and in particular, the third elastic member 432 may be disposed between the third limiting parts 433 and the second connection ears 422, and the third elastic member 432 may be compressed to increase a friction force between the third limiting parts 433 and the second connection ears 422, so that a rotational position of the second display screen mounting part 42 is fixed. Of course, the third elastic member 432 may be disposed between the second connection lug 422 and the first connection lug 413, and the third elastic member 432 may also be disposed between the first connection lug 413 and the third limiting portion 433, and the third elastic member 432 may be compressed to increase the friction force, so as to fix the rotation position of the second display screen mounting portion 42.
In the present exemplary embodiment, the third rotating shaft 431 may be a bolt, the nut of the bolt is one third limiting portion 433, and the other third limiting portion 433 is a nut that mates with the bolt. Of course, in other example embodiments of the present disclosure, the third rotation shaft 431 may be a screw, at both ends of which threads are provided, so that two nuts may be screw-fitted at both ends of the screw. In this case, the two nuts are two limiting portions.
In the present exemplary embodiment, the third elastic member 432 may include a disc-shaped spacer, and the disc-shaped spacers may be provided in two, and the two disc-shaped spacers may be disposed opposite to each other or disposed opposite to each other. Of course, in other example embodiments of the present disclosure, the third elastic member 432 may include a spring.
In the present exemplary embodiment, referring to fig. 11, the distance between the end surface of the third end 4b and the first through hole 4131 is a first distance L1, and the distance between the support end of the second display 5 and the first through hole 4131 is a second distance L2.
The third end 4b is detachably connected to the base 1, so that the second hinge structure 4 and the second display screen 5 can be detached from the base 1 and placed for use independently, and the use mode of the bracket is increased. The second hinge structure 4 forms in this case a "in" shaped support structure with the second display screen 5 for supporting the second display screen 5. Thus, the supporting end of the second display 5 is the end of the second display 5 for supporting.
The ratio of the first distance L1 to the second distance L2 is greater than or equal to 0.8 and less than or equal to 2, for example, the ratio of the first distance L1 to the second distance L2 may be 0.82、0.85、0.87、0.9、0.93、0.95、0.98、1.0、1.02、1.05、1.07、1.1、1.13、1.15、1.18、1.2、1.25、1.3、1.35、1.4、1.45、1.5、1.55、1.6、1.65、1.7、1.75、1.8、1.85、1.9、1.95 or the like.
If the ratio of the first distance L1 to the second distance L2 is too large, the distance L1 between the end face of the third end 4b and the first through hole is too large, and the distance L2 between the supporting end of the second display screen 5 and the first through hole is too small, so that the second display screen 5 cannot be well supported.
If the ratio of the first distance L1 to the second distance L2 is too small, the distance L1 between the end face of the third end 4b and the first through hole is too small, and the distance L2 between the supporting end of the second display screen 5 and the first through hole is too large, so that the adjustment of the inclination angle of the second display screen 5 is limited, which is not beneficial to the user to watch.
The numerical range ensures that the second display screen 5 can be well supported, and ensures that the adjusting range of the inclination angle of the second display screen 5 is larger, thereby being suitable for users to watch under various using states.
Referring to fig. 11 to 14, the inclination angle of the second display 5 gradually increases.
In other example embodiments of the present disclosure, referring to fig. 15, the second hinge structure 4 may further include a fourth rotation shaft structure 44, and the fourth rotation shaft structure 44 is connected between the fourth end 4c and the second display 5 such that the second display 5 is rotatable with respect to the fourth end 4c, that is, the fourth end 4c is rotatably connected with the second display 5 through the fourth rotation shaft structure 44.
For example, referring to fig. 15, a third fixing hole is provided in the third mounting plate 421, a second fixing plate 51 is provided at the back of the second display 5, and a fourth fixing hole is provided in the second fixing plate 51.
The fourth rotating shaft structure 44 may include a fourth rotating shaft 441, a fourth elastic member 442, and two fourth limiting portions 443, and the fourth rotating shaft 441 penetrates through the third fixing through hole and the fourth fixing through hole.
The two fourth limiting portions 443 are disposed at opposite ends of the fourth rotating shaft 441, and the area of the cross section of the fourth limiting portion 443 perpendicular to the axial direction of the fourth rotating shaft 441 is larger than the areas of the third fixing through hole and the fourth fixing through hole, so that the fourth rotating shaft 441 can be limited by the two fourth limiting portions 443, and the fourth rotating shaft 441 is prevented from falling out of the third fixing through hole and the fourth fixing through hole.
The fourth elastic member 442 may be disposed between the two fourth limiting portions 443, the fourth elastic member 442 may be compressed to increase friction between the fourth limiting portions 443, the third mounting plate 421 and the second fixed mounting plate 51, for example, the fourth elastic member 442 may be disposed between the fourth limiting portions 443 and the third mounting plate 421, the fourth elastic member 442 may be disposed between the third mounting plate 421 and the second fixed mounting plate 51, and the fourth elastic member 442 may be disposed between the fourth limiting portions 443 and the second fixed mounting plate 51. After the fourth elastic member 442 is compressed, friction force among the fourth limiting portion 443, the third mounting plate 421, and the second fixing mounting plate 51 can be increased to fix the rotational position of the second display mounting portion 42.
In the present exemplary embodiment, the fourth rotation shaft 441 may be a bolt, and a nut of the bolt is one fourth limiting portion 443, and the other fourth limiting portion 443 is a nut engaged with the bolt. Of course, in other example embodiments of the present disclosure, the fourth rotation shaft 441 may be a screw, at both ends of which threads are provided, so that two nuts may be screw-fitted at both ends of the screw. In this case, the two nuts are two fourth limit portions 443.
In this example embodiment, the fourth elastic member 442 may include a disc-shaped spacer, and the disc-shaped spacers may be provided in two, and the two disc-shaped spacers may be disposed opposite to each other or disposed opposite to each other. Of course, in other example embodiments of the present disclosure, the fourth elastic member 442 may include a spring.
Moreover, the axial direction of the fourth rotating shaft structure 44 intersects with the axial direction of the third rotating shaft structure 43, that is, the fourth rotating shaft 441 of the fourth rotating shaft structure 44 intersects with the third rotating shaft 431 of the third rotating shaft structure 43, for example, the fourth rotating shaft 441 of the fourth rotating shaft structure 44 is perpendicular to the third rotating shaft 431 of the third rotating shaft structure 43, the fourth rotating shaft 441 of the fourth rotating shaft structure 44 may be perpendicular to the display surface of the second display screen 5, and the third rotating shaft 431 of the third rotating shaft structure 43 is parallel to the display surface of the second display screen 5, so that the rotation plane of the fourth rotating shaft structure 44 is perpendicular to the rotation plane of the third rotating shaft structure 43, that is, the second display screen 5 may perform 360 degrees of rotation on the display surface, and the rotation direction of the second display screen 5 is increased, so as to be suitable for more usage environments.
