According to a first aspect of the embodiments of the present application, there is provided a cradle including a main body 10, a first moving part 21, a second moving part 22, a third moving part 23, a connecting member 30, a first guide rail 41, a second guide rail 42, a constant force spring 51, a hook 52, and a base 60, the structure and operation of which will be described in detail below with reference to fig. 1 to 6.

Referring to fig. 1 to 3, in an embodiment, the main body 10 includes a first limiting portion 11, a constant distance is provided between the first moving portion 21 and the second moving portion 22, the first moving portion 21 is matched with the first limiting portion 11 to be guided by the first limiting portion 11, the first limiting portion 11 is configured such that when the second moving portion 22 rotates, the first limiting portion 11 guides the first moving portion 21 to ascend, so that, in the case of connecting the first moving portion 21 and the second moving portion 22 with an object to be supported (in the present embodiment, taking the display 70 as an example), the display 70 may ascend simultaneously when rotating, thereby improving a situation that the display 70 interferes with the stand itself or a supporting surface where the stand is located when rotating, and facilitating an increase of a rotatable angle of the display 70. The support surface referred to herein is the surface of the stand on which the stand is placed in a use state, i.e., a state in which the display 70 is mounted, and it is apparent that the surface provides a supporting force for the stand, and thus the surface is referred to herein as a "support surface" which is substantially located below the display 70. Further, the constant distance between the first moving part 21 and the second moving part 22 as referred to herein is understood to include that the distance between the centers of mass of both the first moving part 21 and the second moving part 22 is constant, and in other examples, it is also understood that the distance between the axes of both the first moving part 21 and the second moving part 22 is constant in the case where both the first moving part 21 and the second moving part 22 have the axes and the two axes are parallel.

In an embodiment, the first moving part 21 may include a slider, and the second moving part 22 may include a turntable assembly, for example, for smoothness of sliding, the first moving part 21 may be a cylindrical slider. In an embodiment, the cylindrical slider is parallel to the axis of the turntable assembly. In an embodiment, as an example, the main body 10 may be a plate member, and the axis of the slider and the turntable assembly may be perpendicular to the plate member. Further, in the embodiment, the first defining part 11 may be a hole penetrating the main body 10, along which the slider slides, and furthermore, in order to ensure the stability of the movement of each moving part and thus the stability of the rotation process of the display 70, the main body 10 may further include a second defining part 12 and a third defining part 13, wherein the second defining part 12 is a bar-shaped hole extending in a vertical direction, in which a part of the second moving part 22 is received and performs a lifting motion along the bar-shaped hole. Similarly, the third defining portion 13 may also be a hole penetrating the main body 10, and the shape of the third defining portion 13 and the shape of the first defining portion 11 will be described in detail in the following description.

In connection with fig. 4 to 6, it is defined that in the use state of the stand, the display 70 has a reference portion below, the display 70 includes a point of an outer contour for defining a trajectory of a movement of the object to be supported, in the embodiment, the display 70 is in a rectangular parallelepiped shape, the point is a point on an edge of the display 70 extending in the thickness direction, and the point is a point which can be closest to the reference portion during the movement of the display 70, see fig. 5, for the example given in fig. 5, when the reference portion has a reference plane 61 inclined as shown in the figure, the point is a vertex of a back side surface, i.e., a left side surface, of the display 70, in the embodiment, the first defining portion 11 is disposed such that a movement trajectory of the point does not interfere with the reference portion, that is, the first movement portion 21 is guided via the first defining portion 11, the first movement portion 21 rises during the movement, the display 70 is also raised simultaneously with the rotation of the display 70 to avoid interference of the one point with the reference portion, and thus, in the case where the one point does not interfere with the reference portion, the rest of the display 70 does not interfere with the reference portion.

In the embodiment, the reference portion may be a member supporting the stand, that is, a member on which the stand is placed, where the ground is the reference portion if the stand is placed on the ground, in the embodiment, the reference portion is a base 60 connected to the main body 10 for supporting the main body 10, the base 60 has an inclined reference plane 61 as mentioned above, which faces the display 70, the reference plane 61 includes a reference line 62 for representing a dimension of the reference plane 61 in a tangential direction of rotation of the second motion portion 22, where the tangential direction is a horizontal direction in fig. 6, in the use state of the stand, the first defining portion 11 is disposed such that a motion locus of the point is directly above the reference line 62 and a part of the motion locus of the point is parallel to the reference line 62, in which case it is advantageous to design the motion locus of the point in advance according to the reference line 62 by setting a minimum distance between the display 70 and the reference line 62, the design process is simplified, and the production efficiency of the support is improved.

In an embodiment, in the case where the length of the portion of the motion trajectory is greater than or equal to the length of the reference line 62, and the length of the portion of the motion trajectory is greater than the length of the reference line 62, both ends of the portion of the motion trajectory respectively exceed both ends of the reference line 62, or one end of the portion of the motion trajectory is flush with one end of the reference line 62, and the other end of the portion of the motion trajectory exceeds the other end of the reference line 62; in another case, the length of the portion of the motion trajectory is equal to the length of the reference line 62, and both ends of the portion of the motion trajectory are flush with both ends of the reference line 62, respectively. Therefore, in the example herein, the movement locus of the point of the display 70 assumes the aforementioned condition due to the configuration of the first defining part 11, which makes the reference line 62 covered by the part of the movement locus when viewed along the extending direction perpendicular to the reference line 62, so that the whole of the reference line 62 can be taken as the basis for designing the structure of the first defining part 11 during the design of the bracket, which further simplifies the design process of the bracket and is advantageous for improving the production efficiency of the bracket.

On the basis of the above-described features, still referring to fig. 2, in the embodiment, the distance between each two of the first moving part 21, the second moving part 22 and the third moving part 23 is constant, and the third moving part 23 is disposed on the turntable assembly, so that the third limiting part 13 is disposed by obtaining the moving track of the third moving part 23 on the basis of the determined first limiting part 11, which further contributes to the stability of the support.

Referring further to fig. 2, in an embodiment, a guide member may be provided to the main body 10, the guide member cooperating with the connection member 30 to guide the connection member 30 along a guide direction (i.e., a vertical direction in the present embodiment) in which the second movement portion 22 is guided by the second defining portion 12, thereby further enabling the turntable assembly to stably perform the elevating movement, and further ensuring stability of the elevating movement of the display 70. Further, an energy accumulating member may be provided to the body 10, and the energy accumulating member may be connected with the connection member 30 and apply a force toward the energy accumulating member to the connection member 30 when the connection member 30 is away from the energy accumulating member. Here, the energy storage member may be disposed above the connection member 30, and the ascending process of the connection member 30 is dragged by the tensile force and the descending process is buffered by the tensile force through the energy storage member.

Still referring to fig. 2, in an embodiment, the guide member may be a guide rail, and in an embodiment, the number of the guide rails is two, wherein one guide rail is defined as a first guide rail 41 and the other guide rail is defined as a second guide rail 42, which are respectively connected to the main body 10 and located at both sides of the connection member 30. In addition, the energy storage member may be a spring, specifically, a constant force spring 51, in the embodiment, three constant force springs 51 are provided, the bracket may further include a hook 52 provided on the connecting member 30, and a lower end of the constant force spring 51 may be hung on the hook 52 to facilitate the detachment and installation.

Referring to fig. 2 and 3, the main body 10 further includes a first locking portion 14, the connecting member 30 includes a second locking portion 31 and a third locking portion, the first locking portion 14 is configured to be engaged with the second locking portion 31 after the second moving portion 22 is rotated by a predetermined angle (the case is not shown in the drawings) to fix the position of the connecting member 30 with respect to the main body 10, and the first locking portion 14 is further configured to be engaged with the third locking portion before the second moving portion 22 is rotated by a predetermined angle (the state is shown in fig. 2) to fix the position of the connecting member 30 with respect to the main body 10. In an embodiment, these locking portions may be all internally threaded holes, and the cooperation between the first locking portion 14 and the second locking portion 31 and between the first locking portion 14 and the third locking portion may be achieved using screws, where the main body 10 includes a protrusion to which the first locking portion 14 is provided to reduce the distance between the first locking portion 14 and the second/third locking portions 31, thereby reducing the length of the screw to be used.

In the embodiment, the predetermined angle as above may be, for example, 90 degrees, that is, the case where the long side of the display 70 is in the horizontal state as shown in fig. 6 may be rotated to the case where the long side not shown in fig. 6 is in the vertical state. As an example, fig. 3 shows the movement process of the three movement portions during the rotation of the display 70 by 90 degrees, wherein the first movement portion 21 moves all the way along the first defining portion 11 from the left side to the right side, the second movement portion 22 rises first along the second defining portion 12 to the highest position of the second defining portion 12 and then falls to the middle position, and the third movement portion 23 starts from the recess portion on the right side, rises first to the highest position of the third defining portion 13 and then falls to the lowest position of the third defining portion 13.
