Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In one embodiment of the present invention, as shown in fig. 1 to 4, there is provided a gravity-balanced stepless hovering support, comprising a device support 10, a fixed hinge 11, a support base 30, an adjustable hinge 40, a support joint 20, a bearing 60, a rotation shaft 61, a guide rod 51, a driving shaft 50, a disc spring 53, etc.
In this embodiment, as shown in fig. 2, the display screen comprises a device bracket 10, the device bracket 10 is fixed with the display screen through screws, the device bracket 10 is connected with a bracket joint 20 through two symmetrical fixed hinges 11, the hinges have damping effect, and at the moment, the display screen can realize rotation and hovering by taking the fixed hinges 11 as the center. The bracket joint 20 is provided with the groove 21, the groove 21 can facilitate the wiring of the display screen cable, and the joint decorative cover 22 can be arranged on the bracket joint 20 to achieve the beautiful effect.
In this embodiment, as shown in fig. 3, the lower end of the joint support 20 is connected to the support bottom plate 30, both sides of the support bottom plate 30 are provided with inner holes, wherein the outer dimensions of the inner hole on one side are identical to those of the adjustable hinge 40, the adjustable hinge 40 is placed in the inner hole of the support bottom plate 30, and the other end of the adjustable hinge 40 is provided with an opening, and is fixed with the joint support 20 by a screw. The adjustable hinge 40 can adjust the damping according to the dead weight of the product, and the joint support 20 can drive the adjustable hinge 40 to rotate.
In this embodiment, as shown in fig. 4, the bearing 60 is placed in the inner hole on the other side of the bracket base plate 30, and the rotation shaft 61 passes through the inner hole of the bearing 60 and the inner hole of the bracket joint 20 and is fixed to the bracket joint 20 by a set screw. The bearing 60 serves as a support, and the inner race is rotatable with the knuckle mount 20. The disc springs 53 are arranged on the side of the bearing 60 at the same time, the concave surface of the uppermost disc spring 53 is upward, the concave surfaces of the middle five pairs of disc springs 53 are opposite to the concave surfaces, the concave surfaces of the lowermost disc spring 53 are downward, and the disc springs 53 are stacked on the guide rod 51 in a butt joint mode, and the outer side of the disc springs 53 is sleeved with a guide barrel to play a guide role. The disc springs can be selected to have proper number of pieces and combination mode according to the compression deformation and the required spring load value. The guide rod 51 sleeved with the disc spring 53 passes through the bottom opening of the bracket bottom plate 30, the upper end hole position of the guide rod is aligned with the opening of the joint bracket 20, the rotating shaft 61 sequentially passes through the inner hole of the joint bracket 20, the inner hole of the guide rod 51 and the inner hole of the joint bracket 20, and finally the rotating shaft 61 is fixed with the joint bracket 20 through the set screw.
In this embodiment, as shown in fig. 5, a lever mechanism is formed in which the bearing 60 is used as a pivot, and the bracket joint 20 is used as a lever. Wherein one end of the lever is the product gravity G, and the other end is the reaction force of the guide rod 51 moving vertically to compress the disc spring 53 plus the resultant force F provided by the adjustable hinge 40. When the balance is realized at the two ends of the lever, the resultant moment of the fulcrum is 0, namely the moment formed by the resultant force F is equal to the moment formed by the product gravity G in magnitude and opposite in direction, a formula of FxL=GxL 2 can be obtained, and meanwhile, according to a trigonometric function L 2＝L1 xcos theta, a formula of F= (GxL 1 xcos theta)/L is finally obtained, wherein L, L 1 and G are constants, and theta is a variable. From the above formula and the characteristic curve of the disc spring, a bracket gravity balance fitting curve is drawn as shown in fig. 6, wherein the abscissa θ is the rotation angle of the joint bracket 20, which corresponds to the deformation of the disc spring, and the ordinate is the load. It can be seen that there is a difference Δf between the function curve of the resultant force F and the characteristic curve of the disc spring, Δf being compensated by the damping value of the adjustable hinge 40, when the disc spring load plus Δf is equal to the resultant force F, the resultant moment at the pivot point is 0, i.e. the bracket achieves gravity balance.
In this embodiment, the large torque hinge is not required to balance gravity, and the disc spring 53 can provide a large force in a small space. When the knuckle mount 20 is at a small angle, the disc spring 53 is less compressed and provides relatively little force, and the moment provided by the adjustable hinge 40 is added to achieve gravitational equilibrium. When the joint support 20 rotates to a large angle, the deformation amount of the disc spring 53 subjected to compression is correspondingly increased, the reaction force is larger, gravity balance can be realized by adding the moment provided by the adjustable hinge 40, and the joint support 20 can be pushed to rotate by only needing a small force, so that hovering at different angles is realized, and the use is convenient.
The foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
