DETAILED DESCRIPTION

[0025] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] Example:

[0028] As shown in the attached drawings, a dual-purpose switchable laptop computer stand includes a fixed base plate 1, a movable base plate 2, a pivot positioning device, a support link 3 and a support plate 4; the movable base plate 2 is rotatably mounted on the fixed base plate 1 via the pivot positioning device; the support plate 4 is movably mounted on the movable base plate 2 via the support link 3, and can be fixed at a use position relatively far from the fixed base plate 1 or at a storage position relatively close to the fixed base plate 1. The dual-purpose switchable laptop computer stand of this embodiment can be used as a support operation for laptop computers and tablet computers or as a stand for placing and displaying products. For details, see the attached drawings. Figure 1 As shown, in the unfolded state of the dual-purpose switchable laptop computer stand, the fixed base plate 1, the support link 3 and the support plate 4 are unfolded at an angle relative to each other, so that the support plate 4 is tilted backwards and is suitable for placing a laptop computer or a tablet computer. In the use state, on the one hand, by adjusting the angle between the movable base plate 2 and the support link 3 or adjusting the angle between the support link 3 and the support plate 4, the support angle of the laptop computer can be changed. On the other hand, by rotating the movable base plate 2, the overall direction of the support plate 4 and its tablet computer can be adjusted without moving the fixed base plate 1, so that the dual-purpose switchable laptop computer stand can better adapt to the user's position and posture or to some special application scenarios. In addition, the provided shaft positioning device can limit the travel of the movable base plate 2 after the direction position of the dual-purpose switchable laptop computer stand is adjusted, so that it maintains the use support state. For the storage state of the dual-purpose switchable laptop computer stand, please refer to the attached Figure 2 As shown, by rotating and folding the movable base plate 2, the supporting link 3 and the supporting plate 4 relative to each other, the components of the entire dual-purpose switchable laptop computer stand can be folded and stored into a relatively compact state, thereby reducing the overall volume and facilitating the storage and placement of the dual-purpose switchable laptop computer stand, product packaging and transportation, etc.

[0029] It is easy to understand that in order to achieve the angle adjustment of the support plate 4, the movable base plate 2 and the support link 3 and the support link 3 and the support plate 4 are connected by a rotating hinge structure. Specifically, as shown in the accompanying drawings, the movable base has a first mounting ear 5 formed by bending upward, and the support plate 4 has a second mounting ear 6 formed by bending backward; one end of the support link 3 is rotatably connected to the first mounting ear 5, and the other end is rotatably connected to the second mounting ear 6. Specifically, after being connected by screws 7, there is a certain rotation resistance between the support link 3 and the support plate 4. After the two are rotated and adjusted toward each other, under the action of the rotation resistance, the two can still maintain a fixed relative position to maintain the adjusted bracket state to support the tablet computer. Similarly, the rotation adjustment principle of the support link 3 is the same as that of the movable base plate 2, which will not be repeated here. In this embodiment, U-shaped grooves 8 are provided between the two sides of the second mounting ear 6 and the support plate 4 bracket to improve its deformation ability, which is conducive to avoiding easy breakage and damage due to impact.

[0030] As a preferred embodiment, a limiting structure for limiting the storage position of the support link 3 is provided on the first mounting ear 5, and the function of the limiting structure is to make the support link 3 be stored in place when stored. For example, in this embodiment, the limiting structure is specifically a limit block 9 extending to the side of the first mounting ear 5. After the limit block 9 is provided, the support link 3 will eventually abut against the limit block 9 when rotating and storing toward the fixed base plate 1. Since the limit blocks 9 on both sides are arranged at the same position, when both support links 3 abut against the limit blocks 9, the rotation amplitude and stroke are the same. By setting the specific position of the limit block 9, it can be ensured that the support plate 4 is parallel to the fixed base plate 1 in the storage state. Through the structural setting of the limit block 9, the user can easily know whether the dual-purpose switchable laptop computer stand is stored in place during specific operation, so that the dual-purpose switchable laptop computer stand is stored in a relatively flat and beautiful state, and the use and operation experience of the dual-purpose switchable laptop computer stand product is improved.

[0031] As described above, in this embodiment, the movable base plate 2 can rotate relative to the fixed base plate 1 to adjust the overall direction, and after the rotation, the movable base plate 2 is restricted and positioned by the rotating shaft positioning device to keep it fixed. Figure 3 and Figure 4As shown, the shaft positioning device of this embodiment specifically includes a fixed plate 10, a rotating piece 11 and a rotation angle positioning structure; the fixed plate 10 is fixedly mounted on the fixed base plate 1 and has a rotation axis area 12; the rotating piece 11 is fixedly connected to the movable base plate 2 and is sleeved on the outside of the rotation axis area 12; the relative rotation between the fixed plate 10 and the rotating piece 11 is limited by the rotation angle positioning structure. In this way, the two rotating pieces 11 clamp the movable base plate 2 and then sleeve on the rotation axis area 12, and can rotate with it as a rotation, thereby driving the movable base plate 2 to rotate together with the supporting connecting rod 3 and the supporting plate 4 to change the adjustment direction.

[0032] In order to realize the restricted positioning of the movable base plate 2 after rotation, as a feasible implementation method, the corner positioning structure includes a limiting tooth ring 13 arranged along the inner ring of the rotating plate 11 and a V-shaped elastic limiting member 14 arranged on the rotating shaft area 12; limiting grooves 15 are evenly spaced on the limiting tooth ring 13; the V-shaped elastic limiting member 14 is arranged in a V-shaped member limiting area formed by a plurality of limiting ribs 16 in the rotating shaft area 12, and part of the V-shaped elastic limiting member 14 protrudes from the outer edge of the rotating shaft area 12. After specific assembly, the V-shaped elastic limiting member 14 is placed in the V-shaped member limiting area. In the initial state, the outwardly protruding part of the V-shaped elastic limiting member 14 can just be stuck in the limiting groove 15 of the limiting tooth ring 13, forming a positioning and rotation restriction effect, that is, realizing the rotation restriction of the movable base plate 2. When it is necessary to rotate the movable base plate 2 to adjust the direction of the support plate 4, when the rotational force applied to the movable base plate 2 is relatively large, the limiting tooth ring 13 will overcome the resistance of the V-shaped elastic limiting member 14 and push it to deform inward, that is, when the rotational force applied is relatively large, the movable base plate 2 can rotate relative to the fixed base plate 1. When the two do not rotate, the V-shaped elastic limiting member 14 will restore its original state under its own elastic action. When it restores its original state, its front end will be restricted by the limiting area of ​​the V-shaped member and re-inserted into the limiting groove 15 of the limiting tooth ring 13, thereby restoring the restricted positioning of the movable base plate 2.

[0033] In this embodiment, the V-shaped elastic stopper 14 includes a first arc-shaped end 141 close to the stopper tooth ring 13 and a second arc-shaped end 142 close to the stopper rib 16. The end of the V-shaped elastic stopper 14 that contacts the stopper tooth ring 13 is set to be in an arc shape. During the relative rotation of the two, the force exerted by the stopper tooth ring 13 on the V-shaped elastic stopper 14 changes relatively smoothly, thereby avoiding the situation where the V-shaped elastic stopper 14 is stuck and cannot rotate or is damaged. Similarly, the two sides of the V-shaped elastic stopper 14 set in the V-shaped part limit area are restricted by the stopper rib 16. The stopper tooth ring 13 rotates and squeezes the V-shaped elastic stopper 14, which causes it to move axially. The other end of the V-shaped elastic stopper 14 is also set to be in an arc shape, which can change the relative force direction between it and the stopper rib 16, so that the V-shaped elastic stopper 14 is easily deformed by force. The corner positioning structure adopting this structure has many advantages such as simple structure, easy implementation, convenient assembly, stable and reliable operation, and low production cost.

[0034] See attached Figure 7 and 8Another embodiment is shown, in which the dual-purpose switchable laptop computer stand further includes a switching switch 17 and a driving device 18, wherein the driving device 18 is meshed with the limiting gear ring 13 for transmission, and the switching switch 17 is used to control the V-shaped elastic limiting member 14 to enter or exit the limiting state. The limiting state here is a state in which the V-shaped elastic limiting member 14 can be freely deformed or reset as described in the above embodiment, forming a state in which the rotation of the movable base plate 2 is restricted and positioned. After the switching switch 17 is set, when the V-shaped elastic limiting member 14 enters the limiting state by operating the switching switch 17, the limiting action principle of the V-shaped elastic limiting member 14 is the same as that of the above embodiment; and when the V-shaped elastic limiting member 14 exits the limiting state by operating the switching switch 17, the V-shaped elastic limiting member 14 does not participate in the rotation restriction and positioning of the movable base plate 2. Specifically, referring to the accompanying drawings, in this embodiment, the V-shaped elastic stopper 14 includes an abutting inclined surface 143 extending backward, and the switching switch 17 is mounted on the fixed disk 10 and its inner end abuts against the abutting inclined surface 143. In this embodiment, when the switching switch 17 is not pressed, it is in the restricted state of the V-shaped elastic stopper 14, and the V-shaped elastic stopper 14 can form a rotation restriction and positioning for the movable base plate 2; when the switching switch 17 is pressed, the switching switch 17 moves backward and is restricted to remain in this state through the relative movement with the abutting inclined surface 143. At this time, the movable base plate 2 is not restricted by the V-shaped elastic stopper 14, the rotation resistance is small, and it can rotate freely. In this state, starting the driving device 18 can drive the movable base plate 2 to rotate, thereby keeping the support plate 4 and the tablet computer placed thereon rotating, that is, the dual-purpose switchable laptop stand of this embodiment can better adapt to the display of products and has better functionality.

[0035] The above only describes the preferred embodiments of the utility model, which should not be construed as limiting the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. In short, all changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
