[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between; when a component is said to be "fixed" to another component, it can be directly fixed to the other component or it can be connected to a component in between.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0030] like Figure 1 As shown, this embodiment provides a foldable portable multi-functional stand, which includes a telescopic panel 1 and a lifting base 2, with the telescopic panel 1 fixed to the top of the lifting base 2.

[0031] like Figure 2 As shown, the lifting base 2 includes a pair of X-shaped legs and a first gas spring 29 connected between the two X-shaped legs. The two legs of the X-shaped legs are hinged by a leg hinge 26, and each leg is composed of an upper leg 24 and a lower leg 27 arranged side by side. Both the upper leg 24 and the lower leg 27 have a degree of freedom of movement along the extension direction of the leg.

[0032] The lifting base 2 in this embodiment has three degrees of freedom for adjustment. The first is adjusting the distance between the two X-shaped legs based on the first gas spring 29; the second is adjusting the included angle of the X-shape based on the hinge of the two legs of the X-shape; and the third is adjusting the length of the legs based on the upper leg 24 and the lower leg 27. Based on these three degrees of freedom, the bracket in this embodiment can meet the adjustment requirements of any height and angle.

[0033] like Figures 3-4As shown, the telescopic panel 1 includes a central fixed plate 6, a left support plate 4, a right support plate 8, and a bottom support plate. The left support plate 4 and the right support plate 8 are respectively arranged on the left and right sides of the central fixed plate 6. The bottom support plate is fixed to the bottom of the central fixed plate 6. The left support plate 4 and the right support plate 8 are connected by a second gas spring 7. The left support plate 4 and the right support plate 8 are respectively hinged to the top of the corresponding legs of the two X-shaped legs. The bottom support plate includes a telescopic rod 16 and a baffle 15. The telescopic rod 16 is connected to the bottom of the central fixed plate 6, and the baffle 15 is fixed on the side of the telescopic rod 16 away from the central fixed plate 6.

[0034] In this embodiment, the telescopic rod 16 can be a damped telescopic rod or a structure that uses a slider and groove. Provided that length adjustment and positioning are possible, this embodiment does not limit the structure of the telescopic rod 16.

[0035] In this embodiment, the telescopic panel 1 adjusts the horizontal width of the telescopic panel 1 by changing the opening range of the left support plate 4 and the right support plate 8 based on the second gas spring 7, and adjusts the vertical length of the telescopic panel 1 by changing the distance between the baffle 15 and the middle fixed plate 6 based on the telescopic rod 16, thereby obtaining a telescopic panel 1 with freely adjustable panel surface to meet the needs of multiple application scenarios.

[0036] In the orientation description of the telescopic panel 1 in this embodiment, ... Figure 3 The surface of the central fixing plate 6 is used as the reference plane, and the top, bottom, left and right sides of the central fixing plate 6 are used as the top, bottom, left and right sides of the reference plane. The length direction of the central fixing plate 6 is the top and bottom direction, and the width direction of the central fixing plate 6 is the left and right direction.

[0037] In order to enable both the upper support leg 24 and the lower support leg 27 to have a degree of freedom of movement along the extension direction of the support leg, in this embodiment, racks are provided on the opposite surfaces of the upper support leg 24 and the lower support leg 27, and the racks of the upper support leg 24 and the lower support leg 27 are connected by gear meshing. Therefore, the upper support leg 24 and the lower support leg 27 provide a degree of freedom of movement along the extension direction of the support leg based on the racks and gears. In addition, for aesthetic purposes and to reduce the risk, a support leg shell 25 is provided on the outside of the upper support leg 24 and the lower support leg 27 to prevent the moving mechanism from being exposed.

[0038] In other embodiments, the degrees of freedom of movement of the upper support leg 24 and the lower support leg 27 can also be achieved based on other mechanisms, such as the cooperation of slide rails or power mechanisms such as motors.

[0039] To improve the user experience, in this embodiment, the two X-shaped legs are tilted 30 degrees to opposite sides and then connected to the first gas spring 29. The X-shaped legs are connected to the first gas spring 29 through a leg retainer 30, which can be a threaded fit, welded, or tenon joint structure, etc.

[0040] In fixing the lifting base 2, the second gas spring 7 can be a gas spring with an automatic control valve or a manual adjustment valve, or a friction gas spring or a balance gas spring, etc., to achieve adjustable and fixed switching. A pneumatic switch 21 is provided on the back of the telescopic panel 1 to adjust the first gas spring 29 and the second gas spring 7. The hinge between the two legs of the X-shaped leg and the degree of automatic movement between the upper leg 24 and the lower leg 27 can be switched between free and fixed states using friction blocks or limit blocks, etc. Furthermore, the state switching between the two legs of the X-shaped leg and between the upper leg 24 and the lower leg 27 can be synchronous or asynchronous. The state switching between the upper leg 24 and the lower leg 27 of different legs can also be synchronous or asynchronous. Under the premise of achieving the corresponding functions, this embodiment does not limit the fixing structure or device of the lifting base 2.

[0041] To improve the ease of use of the support, the bottom of each of the lower support legs 27 in this embodiment is connected to a ball joint 28. The ball joint can be a universal ball joint or the like, to provide the support with a degree of freedom of movement as a whole.

[0042] In this embodiment, the tops of both the upper support leg 24 and the lower support leg 27 are hinged with support leg mounting seats 23. One of the X-shaped legs' support leg mounting seats 23 is hinged to the bottom outer surface of the left support plate 4 and the bottom outer surface of the right support plate 8, respectively. The other X-shaped leg's support leg mounting seat 23 is hinged to a support leg mounting shaft 10 via a support leg seat hinge 22, and the other end of the support leg mounting shaft 10 is hinged to the middle outer surface of the left support plate 4 and the middle outer surface of the right support plate 8, respectively. Based on the hinged connection and the introduction of the support leg mounting shaft 10, the tilt angle and position of the telescopic panel 1 can be changed more flexibly.

[0043] It should be noted that in this embodiment, the bottom and middle of the outer side do not represent absolute positions, but can be a relative range. For example, the middle is the range near the center, and the bottom is the range near the bottom.

[0044] A connecting rod 5 (left connecting rod and right connecting rod) is connected between the middle fixed plate 6 and the left support plate 4 and the right support plate 8 respectively. One end of the connecting rod 5 is hinged to the middle fixed plate 6 and the other end is hinged to the left support plate 4 or the right support plate 8. The fixed positions of the two ends of the same connecting rod 5 are spaced apart along the length of the middle fixed plate 6.

[0045] To enable the extension and retraction of the left and right support plates, recessed clearance grooves are provided on the left and right sides of the central fixed plate 6 and on the sides of the left and right support plates near the central fixed plate 6. These clearance grooves allow the connecting rod 5 to be concealed when the left and right support plates are retracted. Alternatively, the connecting rod 5 can be positioned on the surface or back of the central fixed plate 6 and the left and right support plates. To maximize the utilization of the connecting rod 5, when the left and right support plates are retracted, the distance between the fixed positions of the two ends of the same connecting rod 5 along the length of the central fixed plate 6 is approximately equal to the length of the connecting rod 5 itself.

[0046] Both the left support plate 4 and the right support plate 8 have perforated holes on their surfaces. Clamping plates (including the left clamping plate 3 and the right clamping plate 9) are movably installed inside these holes. The clamping plates are connected to the left support plate 4 or the right support plate 8 via a pivot that passes horizontally through the perforated holes. The clamping plates are primarily designed to provide a clamping function, allowing the telescopic panel 1 to hold items such as books or papers. In this embodiment, the clamping plates include a front plate, a rear plate, and a connecting rod. The front and rear plates are connected by the connecting rod and are in a V-shape. The size of the front plate is adapted to the perforated holes, typically slightly smaller, while the rear plate is smaller. Specifically, one end of the connecting rod connects to the back of the front plate, and the other end connects to the side of the rear plate. The rear plate is connected to the pivot near the V-shaped tip.

[0047] When the front plate and the left and right support plates are on the same plane, the clamp is in a closed state. At this time, the rear plate is located on the back of the left and right support plates, and the rear plate can be limited by limiting the maximum opening angle. When the front plate protrudes towards the front of the left and right support plates, the clamp is in an open state. At this time, the rear plate is located in the hollow hole, and the rear plate can be fixed in the hollow hole by the slot.

[0048] To further widen the telescopic panel 1, the outermost side of the bottom surface of the left support plate 4 in this embodiment is connected to a left extension pivot 14. The extension direction of the left extension pivot 14 is the same as the length direction of the middle fixed plate 6. The left extension pivot 14 is connected to a left extension bracket 12 through a left hinge 13. The rotation surface of the left hinge 13 is perpendicular to the rotation surface of the left extension pivot 14. The end of the left extension bracket 12 away from the left hinge 13 is connected to a left stop bar 11.

[0049] Similarly, the outermost part of the bottom surface of the right support plate 8 is connected to a right extension pivot 17. The extension direction of the right extension pivot 17 is the same as the length direction of the middle fixed plate 6. The right extension pivot 17 is connected to a right extension bracket 19 via a right hinge 18. The rotation surface of the right hinge 18 is perpendicular to the rotation surface of the right extension pivot 17. The end of the right extension bracket 19 away from the right hinge 18 is connected to a right stop bar 20. Figure 5As shown, position A1 represents one direction of rotation of the right extension shaft 17, and the plane containing its rotation direction is considered a vertical plane. Position A2 represents one direction of rotation of the right hinge 18, and the plane containing the rotation direction of the right hinge 18 is a horizontal plane relative to the right extension shaft 17.

[0050] The extension pivot and hinge can be damped pivots and damped hinges, allowing it to stop at any angle. Furthermore, at the installation point of the extension pivot, the surfaces of the left and right support plates are cut into bevels, allowing the extension bracket to tilt towards the bevels to clamp the object.

[0051] In this embodiment, the bracket is stored as follows: Figures 6-7 As shown, it has a compact structure, small size, and is easy to carry.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
