Please refer to Fig. 4, it illustrates the sectional view of part 4 ' among Fig. 3.Base 112 has sliding-groove 1123, groove end face 112t and bottom surface 112b.Sliding-groove 1123 extends to bottom surface 112b from groove end face 112t.When base 112 was positioned over supporting plane S1, balancing weight 1131 was pressed between the upper surface 140u of groove end face 112t and bottom 140.In an embodiment, the external diameter of balancing weight 1131 less than or equal in fact the spacing of the upper surface 140u of groove end face 112t and bottom 140, reduce balancing weight 1131 suffered resistance or frictional force.In addition, supporting plane S1 for example is desktop.
As shown in Figure 4, primary importance P1 is shorter than second place P2 to the distance of supporting post 111 to the distance of supporting post 111.Driving lever 1133 is fixed in balancing weight 1131, and for example driving lever 1133 is fixed in balancing weight 1131 with its end 1133d.The process of balancing weight 1131 from second place P2 to primary importance P1, elastic element 1132 deformation and storage elasticity potential energy.So, when balancing weight 1131 was positioned at primary importance P1, elastic element 1132 stored the elasticity potential energy.
As shown in Figure 4, display device 100 more comprises elastic element 150, and it can be located on base 112 or the bottom 140.When driving lever 1133 was moved toward the direction of second place P2 by primary importance P1, driving lever 1133 can be toward bottom offset or toward top rake, to break away from the backstop of stop rib 1125.The backstop that breaks away from stop rib 1125 when driving lever 1,133 one, the elasticity potential energy of elastic element 1132 just can drive balancing weight 1131 from primary importance P1 toward second place P2.Elastic element 150 for example is the combination of shell fragment, spring or shell fragment and spring.Aforesaid " driving lever 1133 can be toward top rake " referring to: the first limited part 1133a of driving lever 1133 is toward having a down dip, and the second limited part 1133b of driving lever 1133 is toward tilting, and so the first limited part 1133a of driving lever 1133 can break away from the backstop of stop rib 1125.
In addition, when elastic element 150 was shell fragment, the free end of elastic element 150 was towards the direction of second place P2.Because the free end of elastic element 150 is towards the direction of second place P2, thus when the first limited part 1133a when having a down dip, but the free end deformation of elastic element 150 and the first limited part 1133a can past be had a down dip.
Please refer to Fig. 5, it illustrates the controlled schematic diagram of visible angle of the screen of Fig. 4, when the user adjusts the visible angle of screen 120, as described in epimere, promote the backstop that driving lever 1133 breaks away from stop rib 1125, the elasticity potential energy of elastic element 1132 just can drive balancing weight 1131 from primary importance P1 toward second place P2.Move in the process of second place P2 at balancing weight 1131, balancing weight 1131 is far away to the distance of supporting post 111, thus, just as balancing weight 1131 to the pin-joint part 130 the arm of force longer, make that display device 100 is unlikely topples over.
Because driving lever 1133 is fixed in balancing weight 1131, when balancing weight 1131 moved from primary importance P1 toward second place P2, driving lever 1133 was with balancing weight 1131 interlocks.
When balancing weight 1131 is positioned at second place P2, elastic element 1132 can be in free state, and so this is non-in order to limit the present invention.In an embodiment, the first limited part 1133a of elastic element 1132 is subject to keeping some amount of tension in the situation that spacing cell wall 114s1 backstop or the second limited part 1133b be subject to sidewall 1124 backstops.
When balancing weight 1131 is positioned at second place P2, sees through pulling driving lever 1133 and balancing weight 1131 can be moved to primary importance P1 from second place P2.
Driving lever 1133 and balancing weight 1131 can be that two resolution elements see through locking or the securement techniques such as bonding is combined; Perhaps, driving lever 1133 and balancing weight 1131 can be integrally formed structures.Yet, the weight of the weight visual screen 120 of balancing weight 1131 and/or size and decide, as long as in the process of the visible angle of adjusting screen 120, the weight of balancing weight 1131 can be avoided screen 120 to topple over getting final product, and the present embodiment is not limited the weight of balancing weight 1131.
As shown in Figure 4, base 112 has restraining groove 114.The first limited part 1133a of driving lever 1133 is located in the restraining groove 114 slidably.Because the first limited part 1133a is limited in the restraining groove 114, therefore can avoid driving lever 1133 and supporting post 111 to break away from.
Please be simultaneously with reference to Fig. 4 and Fig. 6, Fig. 6 illustrates the enlarged view of the driving lever of Fig. 1.The first limited part 1133a comprises the first Shock absorbing cushion 1133c, and the first limited part 1133a contacts spacing cell wall 114s1 and 114s2 with the first Shock absorbing cushion 1133c.In the present embodiment, the first limited part 1133a comprises two the first Shock absorbing cushion 1133c, and it is the relative both sides of the first limited part 1133a, so, produces violent noise in the time of can avoiding the driving lever 1133 spacing cell wall 114s1 of bump and 114s2.In an embodiment, the first Shock absorbing cushion 1133c is also configurable on base 112.Among another embodiment, the second limited part 1133b also can comprise the first Shock absorbing cushion 1133c.
Be the example explanation although above-described embodiment Elastic element 1132 stores the elasticity potential energy so that balancing weight 1131 is positioned at primary importance P1, so among another embodiment, elastic element 1132 also can be when balancing weight 1131 be positioned at the second place P2 storage elasticity potential energy.Below take Fig. 7 as the example explanation.
Please refer to Fig. 7, it illustrates the partial sectional view that the supporting frame according to another embodiment of the present invention shows.Primary importance P1 is shorter than second place P2 to the distance of supporting post 111 to the distance of supporting post 111.Compared to second place P2, balancing weight 1131 is positioned at the arm of force that primary importance P1 can obtain to grow, and makes when adjusting the visible angle of screen 120 (not being illustrated in Fig. 7), and display device 100 (not being illustrated in Fig. 7) is unlikely topples over.
In addition, the process of balancing weight 1131 from primary importance P1 to second place P2, elastic element 1132 deformation and storage elasticity potential energy.Say further, when balancing weight 1131 was positioned at second place P2, elastic element 1132 stored the elasticity potential energy.
When balancing weight 1131 was positioned at second place P2, the first limited part 1133a of driving lever 1133 can be subject to the backstop (as shown in Figure 7) of stop rib 2125, and avoided elastic element 1132 to discharge the elasticity potential energies and balancing weight 1131 is driven to primary importance P1.
When driving lever 1133 moves from second place P2 toward the direction of primary importance P1 and when breaking away from the backstop of stop rib 2125, elastic element 1132 is released the elasticity potential energy and drives balancing weight 1131 and move from second place P2 toward primary importance P1.
In the present embodiment, driving lever 1133 can not be fixed in balancing weight 1131, so also can be fixed in balancing weight 1131.When balancing weight 1131 moved from second place P2 toward primary importance P1, even driving lever 1133 is not fixed in balancing weight 1131, driving lever 1133 still can be subject to the promotion of balancing weight 1131 and move.When balancing weight 1131 is positioned at primary importance P1, sees through promotion driving lever 1133 and balancing weight 1131 can be moved to second place P2 from primary importance P1.
In addition, when balancing weight 1131 is positioned at primary importance P1, elastic element 1132 can be in free state, and so this is non-in order to limit the present invention.In an embodiment, elastic element 1132 can keep some amount of tension in the situation that the first limited part 1133a is subject to spacing cell wall 114s2 backstop.
The supporting frame of the above embodiment of the present invention and use its display device, can in the situation that not fixing support rack adjust the visible angle of screen, the user is provided easy adjustment mode.
In sum, although the present invention discloses as above with embodiment, so it is not to limit the present invention.The persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is as the criterion when looking the claim scope person of defining.
