Detailed Description
In order to clearly understand the technical contents of the present invention, the following examples are given in detail.
As shown in fig. 1 to 6, the embodiment of the display stand with a freely adjustable height adopted in the present invention is shown, wherein the display stand includes a base 1 and a connector 4 for mounting a display, the display is fixed on the connector 4 through a mounting plate 5, an upper connecting arm 2 and a lower connecting arm 3 are arranged between the base 1 and the connector 4 in parallel, and as shown in fig. 4, a hinge point C between the upper connecting arm 2 and the connector 4, a hinge point D between the lower connecting arm 3 and the connector 4, the lower connecting arm 3, a hinge point B between the lower connecting arm 3 and the base 1, a hinge point a between the base 1 and the upper connecting arm 2 and the base 1, and a quadrilateral structure ABDC between the upper connecting arm 1 are formed.
As shown in fig. 1 to 3, the display support comprises a mechanical spring 6, one end of the mechanical spring 6 is hinged to the connector 4, the other end of the mechanical spring 6 is hinged to a threaded slider 7, the threaded slider 7 is sleeved on a threaded rod 8, and the threaded rod 8 is arranged in the base 1. One end of the threaded rod is set as an operating end, and the other end of the threaded rod is rotatably arranged in the mounting seat, so that the operating end of the threaded rod is applied with force to drive the threaded rod to rotate. When the end of the threaded rod 8 is operated to drive the threaded rod 8 to rotate, the threaded slider 7 can move along the threaded rod 8. As shown in fig. 2, the threaded slider 7 is now at the highest end of the threaded rod 8; as shown in fig. 3, the thread slider 7 is at the lowermost end of the threaded rod 8, and by operating the threaded rod 8, it is possible to move the thread slider 7 between the uppermost end and the lowermost end of the threaded rod 8.
The position of the threaded slider 7 on the threaded rod is adjusted according to the weight of the display on the connecting head 4, so that the connecting head 4 can be freely stopped at different heights relative to the base 1 when the connecting head 4 is moved upwards or downwards.
In the embodiment provided by the present invention, one end of the mechanical spring 6 is hinged to the connecting head 4, and optionally, the end of the mechanical spring 6 may also be hinged to the lower connecting arm 3.
In the embodiment provided by the invention, one end of the mechanical spring is hinged on the connecting head, the other end of the mechanical spring is hinged with the threaded slider, the threaded slider is in threaded connection with the threaded rod, the three are installed on the base together, and as shown in figures 2-3, the mechanical spring is in a stretching state. The threaded rod can be rotated by a hexagonal wrench, so that the threaded slider moves up and down on the threaded rod, the angle between the mechanical spring and the upper connecting arm or the angle between the mechanical spring and the lower connecting arm is changed, and free stop in the aspect of height of different loads is realized. The sliding range of the threaded sliding block and the installation position of the corresponding threaded rod can be designed, and the display with the required bearing range can be freely stopped.
Therefore, in order to realize the free stop of the display within the required bearing range, the display bracket provided by the invention simultaneously meets the following balance conditions:
the first balance condition: the connector is kept at any height in a preset height range, the threaded rod is driven to rotate to drive the threaded slider to move, and gravity torque M1 is guaranteed to be elastic torque M2 so as to be matched with a display with any weight in a preset weight range.
Second equilibrium conditions: according to the first balance condition, the position of the threaded slider in the threaded rod corresponding to the weight of the display is maintained, and when the height of the connector is changed at will within the preset height range, the gravity torque M1 is ensured to be equal to the elastic torque M2, so that the connector can be stopped freely at different heights relative to the base.
For the first balance condition, as shown in fig. 4, the connector is kept at any height in the preset height range, that is, the angle a between the upper connecting arm or the lower connecting arm and the horizontal plane is not changed, at this time, for the display adapted to any weight in the preset weight range, the threaded rod can be rotated by using a hexagonal wrench, so that the threaded slider moves up and down on the special threaded rod, and the position of the threaded slider on the threaded rod is changed, that is, the angle b between the mechanical spring and the upper connecting arm or the lower connecting arm is changed.
The gravity torque M1 ═ GL ═ cos (a) ═ elastic torque M2 ═ F ═ L ═ sin (b), where L is the length of the upper or lower link arm, G is gravity, and F is elastic force, the product is obtained
Since the angle a is constant and the spring force F is also constant, when b decreases (the screw slider slides down), G decreases, i.e. the display weight decreases. Thus, for a display in the preset weight range, the weight is reduced, b is reduced, the lower the screw slide position. As shown in fig. 4, point E is the highest point of the threaded slider, and the angle b between the mechanical spring and the upper connecting arm or the lower connecting arm is the largest at this time; and point F is the lowest point of the sliding of the threaded sliding block, and the angle b between the mechanical spring and the upper connecting arm or the lower connecting arm is the minimum.
For the second equilibrium condition, the display weight is constant, the position of the threaded slider in the threaded rod is constant, and the angle a can be changed arbitrarily within a preset angle range by adjusting the display position up and down, in the process, the gravity torque M1 is equal to the elastic torque M2.
Assuming that the preset range of the angle a is (33 °, -33 °), when the angle a changes from 33 ° to-33 °, the elastic force F is continuously increased due to the constant stretching of the mechanical spring, and to make M1 equal to M2, the angle b between the mechanical spring and the upper or lower connecting arm needs to be continuously decreased to ensure that the torque M2 provided by the elastic force is basically constant.
Therefore, the movement track of the corresponding threaded rod setting position/threaded slider can be calculated and obtained according to the preset weight range and the preset height range/preset angle range.
As shown in fig. 5, based on the first balance condition and the second balance condition, the initial motion trajectory of the threaded slider can be determined, that is, a circle C is drawn by taking a connection point G of the mechanical spring on the connection head as a center of a circle, a length L1 of the mechanical spring when the connection head is at a preset maximum height as a radius, an included angle b between the mechanical spring and the upper connection arm or the lower connection arm forms a straight line La and Lb passing through the point G when the included angle b is at a maximum value and a minimum value, a point e and a point f are formed by an intersection point of the circle C and the straight lines La and Lb, and a line segment ef is translated up and down by 5mm along a direction perpendicular to the line segment ef to obtain a1f1And e2f2Forming a range of motion trajectories of the threaded slider, quadrilateral e1f1f2e2。
And when the connector is kept at any horizontal height in the preset height range, obtaining the maximum value and the minimum value of an included angle b between the mechanical spring and the upper connecting arm or the lower connecting arm according to the maximum value and the minimum value of the preset weight range of the display.
That is, the motion track of the threaded slider is located in a quadrilateral e1f1f2e2Two points in (e)0And point f0Connected line segment e0f0As shown in FIG. 4, an included angle α between the threaded rod and the horizontal direction far away from the connector is preferably 0-80°。
To further determine the movement track of the threaded slider, it can be determined by the elastic coefficient of the mechanical spring. For the same spring, the stiffness K (elastic coefficient) of the spring needs to be a certain value or the difference in magnitude is not large. When the increment delta F based on K ═ spring force/the deformation quantity delta X of the mechanical spring is a certain value or the difference in magnitude is not large, the motion track of the threaded slider can be verified through the following formula, and the elastic coefficient of the mechanical spring is determined.
Wherein G is the weight of the display;
a1, a2 is the angle between the upper connecting arm or the lower connecting arm and the horizontal plane when the connecting head is at any two heights in the preset height range;
b1 and b2 are respectively included angles between the mechanical springs corresponding to a1 and a2 and the upper connecting arm or the lower connecting arm;
l1 and L1' are lengths of the mechanical springs corresponding to a1 and a2 respectively, and are obtained through actual measurement.
Through the formula, a plurality of K values can be obtained, and the elastic coefficient K of the mechanical spring is selected from Kmin to Kmax, wherein Kmax to Kmin is less than or equal to 15; can verify the line segment e0f0If the position of any point on the screw thread slider meets the requirement, the position can be slightly adjusted, the position can be verified again, the actually obtained point can float up and down, and the finally drawn straight line is used as the final motion track of the screw thread slider.
When the connector be in predetermineeing the maximum height, mechanical spring's length L1 set up to L-x, wherein, L be mechanical spring with the connector or the distance between the pin joint of lower link arm and base to the tie point of lower link arm, x is-10 ~ 30 mm. In order to satisfy the second equilibrium condition, when the predetermined angle/height range is changed, theoretically, when the angle a is at a maximum, the mechanical spring length L1> -L can ensure that the angle b is constantly decreasing when rotating downward. However, in practice, the gravity force provides a torque M1 which is GL × cos (a), the gravity force G is constant, and in the initial stage, when the angle a is from 33 ° to 0 °, the torque M1 of the gravity force is increasing, the change value is not large, particularly, the change of the torque of the gravity force is negligible in the latter half due to the large change of the elastic force, and the torque of the gravity force is regarded as a constant value. Therefore, the length L1 of the mechanical spring is set to be L-x, and x is-10-30 mm.
Specifically, taking the display bearing 2-9 kg as an example, the change of the set angle a is from 33 ° to-33 °, the weight of the part is calculated, G is calculated according to 30-100N, and assuming that the elastic force F is 700N, the minimum value bmin is about 2 °, and the maximum value bmax is about 7.5 °; l240 mm, x 5mm, L1 235 mm.
As shown in fig. 6, the display bracket includes an adjusting lever 10, one end of the adjusting lever 10 is hinged to the connector or the lower connecting arm, the other end of the adjusting lever 10 is in threaded connection with one end of the mechanical spring 6, and when the end of the adjusting lever is operated to drive the adjusting lever to rotate, the mechanical spring is driven to extend and retract so as to adjust the elastic force of the mechanical spring to adapt to the display within the preset weight range.
If only the mechanical spring is arranged, namely the tension of the mechanical spring is set, the adjustment cannot be carried out; after the adjusting rod is installed, the elasticity is controllable, the adjusting rod can be rotated to control the stretching of the mechanical spring, and the elasticity is changed; by adjusting the elastic force, the weight range of the display can be set more flexibly. For example, the elastic force is 700N, the weight of the display is 2-9 kg, and if the elastic force is adjusted to 800N, 3-11 kg can be achieved.
The display support with the freely adjustable height uses the mechanical spring to realize the freely stop of height adjustment, and is better than a gas spring support.
In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
