the first pivot axis and the second pivot axis are arranged in parallel;
the universal joint transmission mechanism at least comprises two universal joints which are connected in sequence;
one outer end of the universal joint transmission mechanism is fixedly connected with the base relatively in the circumferential direction of the first pivot axis; the other outer end of the universal joint transmission mechanism is fixedly connected with the screen connecting seat relatively in the circumferential direction of the second pivot axis;
when the swing bracket is lifted or falls, the included angle between the swing bracket and the base correspondingly changes in a follow-up manner, and the screen connecting seat translates relative to the base without rotating.
In the invention, the screen connecting seat can also be called as a following seat, the transmission ratio of the whole universal joint transmission mechanism is 1, and when the swing bracket is lifted or falls down, the screen connecting seat moves in parallel relative to the base, and the clamping angle of the screen connecting seat and the base is unchanged. Compared with the prior art, the universal joint realizes torque transmission or transmission with variable angles, has the advantages of simple structure, simple and convenient manufacture, higher reliability and longer service life, and particularly, compared with the prior gear transmission pair and the prior connecting rod transmission mechanism, the universal joint transmission mechanism is small and exquisite, occupies small space, and the display support frame (particularly the swinging support frame part) can be made to be very thin, and the thickness of the display support frame is only 1/2 of that of the gear transmission pair and the connecting rod transmission mechanism support frame.
In the invention, the universal joint is a transmission unit capable of realizing torque transmission and rotation transmission between two rotating parts, wherein the two rotating parts are arranged at an included angle and the axes are intersected.
Typically, a universal joint comprises two rotational joints arranged at an angle for angular transmission, i.e. variable angle transmission, between two rotatable members. For example, a cross-type universal joint includes a pair of hinges (i.e., revolute joints) oriented 90 ° relative to each other, connected by one or a short or long rod or shaft.
Further, a torsion spring or a tension spring is arranged between the base and the swing bracket, and the torsion spring or the tension spring tends to force the swing bracket to lift up, so that a supporting force for supporting the display is provided.
The elastic force of the torsion spring or the tension spring can be changed in the process of being stretched, so that the supporting force provided by the torsion spring or the tension spring is changed, and the display cannot be stopped along with the lifting process. Compared with other transmission pairs such as gears, four connecting rods and the like, the universal joint in the universal joint transmission mechanism has larger damping force in the variable angle/direction transmission process, namely, the resistance which tends to prevent the swinging bracket from swinging is automatically generated, and the resistance and the supporting force are mutually combined, so that the display can stop along with the lifting process without adding an additional damper, thereby greatly reducing the production cost.
