Description

Screen positioning mechanism and display device combined with different forms of rotating shafts

technical field

The invention provides a screen positioning mechanism and a display device combining different forms of rotating shafts, especially a screen positioning mechanism and a display device combining a vertical tripod-shaped rotating shaft and a photo frame-shaped tripod-shaped rotating shaft.

Background technique

Recently, the all-in-one computer (All in one PC) has gradually become the mainstream of the market, but the form of its stand is nothing more than the old monitor stand specification, and the photo frame stand and general stand stand are the most commonly used stand forms. . The current sales model of all-in-one computers on the market is the same as that of the old LCD screens. Consumers must decide on the tripod form in advance, and the standard replacement hole (Vesa Hold) is not listed as a standard specification by every manufacturer. Therefore, if consumers want to It is quite difficult to change the form of tripod (such as photo frame tripod, vertical tripod, etc.). Please refer to Fig. 1, Fig. 1 is the structural representation of a vertical stand mechanism 10 of the prior art, its feature is that a screen 12 is fixed on a mandrel 16 of a base 14, the weight of screen 12 is transmitted to the base via mandrel 16 14 and the desktop carrying the base 14. In addition, the screen 12 can also rotate around the mandrel 16 within a specific angle range. In order to achieve the purpose of labor saving and uniform force, a torsion spring assembly is usually installed on the mandrel 16, and because the screen 12 The direction of the moment caused by the weight is the direction that makes θ smaller, so the torque provided by the torsion spring assembly must be in the direction that makes θ larger, so as to offset the moment generated by the weight of the screen 12, thereby achieving the purpose of labor saving.

In addition, referring to Fig. 2, Fig. 2 is a structural schematic diagram of a picture frame type tripod mechanism 20 of the prior art, the front edge of a screen 22 and a support 24 that the photo frame type tripod mechanism 20 is used to support are all in contact with the desktop, therefore There are two front and rear contact points, and the photo frame type tripod mechanism 20 is usually designed so that the back angle can be adjusted. The adjustment method can be divided into two types. One is to keep the bracket 24 fixed by sliding the lower edge of the screen 22 on the desktop , to achieve the purpose of adjusting the reclining angle; the other is the opposite, that is, the contact point between the screen 22 and the desktop remains stationary and the bracket 24 slides on the desktop, because the weight of the screen 22 will cause the bracket 24 to slide backwards, so A mandrel 26 connecting the screen 22 and the bracket 24 needs to provide a large enough frictional moment to avoid this phenomenon. For convenience, the bracket can be retracted automatically when the user lowers the recline angle, and the user does not have to use the other hand to hold it back. Pull it back, and a torsion spring assembly can be installed on the mandrel 26. Since the direction of the torque generated by the weight of the screen 22 on the bracket 24 is the direction in which θ becomes larger, the torque provided by the torsion spring assembly should be in the direction of making θ smaller. , so as to reduce the friction torque and achieve the purpose of labor saving.

As can be seen from the above, since the mechanical structure of the hinge of the vertical tripod mechanism and the photo frame tripod mechanism is the opposite principle, that is, the torque provided by the torsion spring assembly is different from that of the photo frame tripod when the traditional vertical tripod mechanism is used. The direction of the stand mechanism is opposite when used, and due to the limitation of the mechanism design, there is no shared structure between the vertical tripod and the photo frame tripod on the market, and can only be divided into two separate tripods. However, the vertical tripod and the photo frame tripod Photo frame tripods have their own limitations in use. For example, the θ angle range of the traditional vertical tripod mechanism is -5 to 20 degrees, while the θ angle range of the traditional photo frame tripod mechanism is 20 to 62 degrees. In the vertical tripod mechanism mode shown in 1, a screen reclining angle α of the screen 12 is equal to θ (inverted angle), and in the picture frame type tripod mechanism mode shown in Figure 2, the screen 22, the support 24, and the bearing The triangle formed by the surface is approximately an isosceles triangle, so the size of the screen back elevation angle α is about one-half of θ. If the specifications require that the range of the vertical tripod's back angle is -5 to 20 degrees, and the range of the picture frame type tripod's back angle is 15 to 30 degrees, set the angle range of the θ angle to -5 to 20 degrees for the vertical tripod , 25-62 degrees for the photo frame tripod is acceptable under certain conditions. Based on the above, different types of tripods can position the screen at different angle ranges. If a breakthrough can be made to combine the vertical tripod mechanism and the photo frame tripod mechanism on the same base structure, the product competitiveness can be effectively improved. .

The screen positioning mechanism 56 further includes a second shaft module 84, which is connected to a second end 582 of the carrier 58. Basically, the structure of the second shaft module 84 is similar to that of the first shaft module 60. Here is an introduction, and the structures and functions of other identical components will not be described in detail here. The second shaft module 84 includes a second preload angle control washer 86, on which is provided a second limiting structure 861, the second limiting structure 861 can be an arc groove; the second shaft module 84 also includes a second load assembly 88 , the second load assembly 88 can be a torsion spring, and a fixed end 881 of the second load assembly 88 is fixed on the second end 582 of the carrier 58, such as can be inserted into the hole on the second end 582, and the second load assembly 88 An active end 882 of the second precompression angle control washer 86 passes through the second limiting structure 861 .

Since the first load assembly 76 and the second load assembly 88 are arranged in opposite directions, the direction of the torque they provide is also opposite. In the present invention, the first shaft module 60 and the second shaft module 84 can be designed as vertical tripods respectively. mode and photo frame tripod mode, or the first shaft module 60 and the second shaft module 84 are designed to be the shaft mechanisms applicable to the photo frame tripod mode and the vertical tripod mode respectively.

Please refer to FIG. 8 . FIG. 8 shows the first load component 76 and the second load component 88 respectively in the first limiting structure 621 of the first preload angle control washer 62 and the second preload angle control washer 86 in different states. Schematic diagram of relative positions within the two defined structures 861 . For example, when the θ angle between the screen 52 and the bracket 541 is within a first range, such as in the vertical stand mode shown in FIG. The components 76 are all in a preloaded state and their movable ends 762 abut against the endpoints of the first limiting structure 621, and when the screen 52 rotates within the first range because the first load components 76 are all in a preloaded state, so the first load component 76 is in a preloaded state. The movable end 762 of a load component 76 will always be in contact with the end point of the first limiting structure 621, so that through this abutting contact, the first load component 76 can provide a torque in a first direction to the first preload angle The washer 62 is controlled and transmitted to the carrier 58. Since the direction of the moment caused by the weight of the screen 52 in the vertical stand mode shown in FIG. In order to offset the moment generated by the weight of the screen 52, and then achieve the purpose of labor saving, the first shaft module 60 is the shaft mechanism used in the vertical tripod mode; at the same time, when the screen 52 and the bearing surface 55 When the angle between them is within the first range, a movable end 882 of the second load component 88 is not in contact with the end point of the second limiting structure 861 of the second preload angle control washer 86 in the second limiting structure 861. Sliding means that the second load assembly 88 is in a released state, and the second load assembly 88 cannot provide torque to the bearing member 58 at this time.

As mentioned above, when the angle between the screen 52 and the bearing surface 55 is within the first range, that is to say, in the stand mode, only the first load assembly 76 of the first hinge module 60 will provide torque to the bearing member 58 , and the second load assembly 88 of the second shaft module 84 is in a released state and cannot provide torque to the bearing member 58 , so the torque generated by the first load assembly 76 will not be counteracted.

When the angle of the θ angle between the screen 52 and the bracket 541 is between a second range different from the first range, such as in the photo frame tripod mode shown in FIG. At this time, the first load component 76 is no longer in the preloaded state and its movable end 762 slides on the first limiting structure 621 in a manner that does not abut against the end point of the first limiting structure 621 of the first preloading angle control washer 62 , and also That is, the first load assembly 76 is in a released state, and at this time, the first load assembly 76 cannot provide torque to the bearing member 58; at the same time, the second load assembly 88 is in a preload state and its movable end 882 abuts against the second preload angle The end point of the second limiting structure 861 of the control washer 86, and when the screen 52 rotates within the second range, because the second load component 88 is in a pre-compressed state, the movable end 882 of the second load component 88 will always abut against the The end point of the second limiting structure 861, so that by this abutting contact, the second load assembly 88 can provide a torque in a second direction opposite to the first direction to the second preload angle control washer 86 and transmit it to the second precompression angle control washer 86. Bearing member 58, since the direction of moment caused by the weight of screen 52 in the photo frame tripod mode shown in FIG. That is to say, in order to allow the user to retract the bracket 541 automatically when the reclining angle is reduced, and the user does not need to pull it back with the other hand, a second load assembly 88 can be added to offset the moment generated by the weight of the screen 52 . At this time, the second hinge module 84 is a hinge mechanism used in the photo frame tripod mode.

As mentioned above, when the angle between the screen 52 and the supporting surface 55 is within the second range, that is to say, in the photo frame tripod mode, only the second load assembly 88 of the second hinge module 84 will provide torque to the bearing member 58 , but the first load assembly 76 of the first shaft module 60 is in a released state and cannot provide torque to the bearing member 58 , so the torque generated by the second load assembly 88 will not be counteracted. In addition, the angles in the first range and the angles in the second range may partially overlap or not overlap at all. For example, although the angles in the first range and the angles in the second range partially overlap, the effect of the load component in a certain mode will be weakened. However, it is still a feasible solution under the premise that it does not cause the nodding phenomenon (due to insufficient torque, the screen will automatically sag (reclining angle becomes smaller) when the user does not apply external force) and the push-pull force is acceptable; or the When the angles in the first range and the angles in the second range are completely non-overlapping or even not continuous, it is still a feasible solution if the pre-compression angle of the load assembly can provide enough torque to automatically retract the bracket.

In addition, since the screen positioning mechanism 56 of the present invention has two modes of use: a vertical stand mode and a photo frame stand mode, and different use modes have different requirements for friction torque. Taking the first shaft module 60 as an example, The purpose of adjusting the friction torque can be achieved through the structural design of the first friction torque control washer 70 and the second friction torque control washer 72 . When the screen 52 is in the standing stand mode as shown in FIG. The positive frictional force between a friction torque control washer 70 and the second friction torque control washer 72 is relatively large, so that the whole body will provide a large friction torque in the vertical tripod mode; and when the screen 52 is as shown in the figure 4 is in the photo frame tripod mode, the first protrusion 701 of the first friction torque control washer 70 will not contact the second protrusion 721 of the second friction torque control washer 72, at this time the first friction torque The positive frictional force between the control washer 70 and the second friction torque control washer 72 is relatively small, so in the photo frame type tripod mode, the whole body will provide a small friction torque, which meets the requirements of the shaft module in the vertical tripod mode. It is an actual requirement to provide a larger friction torque and a smaller friction torque for the shaft module in the photo frame tripod mode. The size of the friction torque can be controlled by the thickness of the spacer 74 .

Based on the above, the screen positioning mechanism 56 of the present invention integrates two types of shaft mechanism designs with different specifications, that is, the first shaft module 60 and the second shaft module 84 are designed for the vertical tripod mode and the photo frame tripod mode respectively The applicable rotating shaft mechanism is different from the prior art in which the rotating shaft mechanisms on the left and right sides of the base are the same torsion spring design. In addition, in order to solve the problem that the torque directions of the two torsion springs are opposite and may cause mutual cancellation, the present invention is designed so that when the vertical tripod mode is used, the first shaft module 60 suitable for the vertical tripod mode can act as Torque is provided to the screen 52, while the second shaft module 84 suitable for the photo frame tripod mode is out of action and cannot provide torque to the screen 52; conversely, when the photo frame tripod mode is used, it is suitable for the photo frame tripod mode The second hinge module 84 can function to provide torque to the screen 52 , while the first hinge module 60 suitable for the stand mode is disabled and cannot provide torque to the screen 52 .

Moreover, the present invention utilizes the fixed end 761 of the first load assembly 76 and the fixed end 881 of the second load assembly 88 to be respectively fixed on the first end 581 and the second end 582 of the carrier 581, and the movement of the first load assembly 76 The end 762 and the movable end 882 of the second load assembly 88 are slidably arranged on the first limiting structure 621 of the first preload angle control washer 62 and the second limiting structure 861 of the second preload angle control washer 86 respectively. Structural design to achieve the function of only activating one type of hinge module to provide screen positioning in one mode of use, that is, the first load component 76 and the second load component 88 need to be designed so that one end is fixed and the other end is movable Therefore, the present invention can also be designed to form the first limiting structure 621 and the second limiting structure 861 on the first end 581 and the second end 582 of the carrier 581 respectively, so that the fixed end 761 of the first load assembly 76 and the second The fixed end 881 of the load assembly 88 is respectively fixed to the first preload angle control washer 62 and the second preload angle control washer 86, and the movable end 762 of the first load assembly 76 and the movable end 882 of the second load assembly 88 are respectively connected to It is slidably arranged in the first limiting structure 621 of the first end 581 of the carrier 581 and the second limiting structure 861 of the second end 582 of the carrier 581. No longer.

Compared with the prior art, the screen positioning mechanism and the display device provided by the present invention combine the vertical tripod form rotating shaft and the photo frame tripod form rotating shaft at the same time, so the vertical tripod mode and the photo frame type can be provided on the same display device. There are two different usage modes of the tripod mode, which can not only increase the range of screen positioning angles, but also provide users with a variety of tripod form changes, so it is a niche product design.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the claims of the present invention shall fall within the scope of the patent of the present invention.
