[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] The multifunctional screen base provided by the embodiment of the present invention Figures 1 - 14 As shown, a base assembly 1 and a support assembly 2;

[0059] The base assembly 1 includes: a first base 11 and a second base 12;

[0060] The first base 11 is detachably installed on the second base 12, and the vertical projection area of the first base 11 is smaller than the vertical projection area of the second base. The vertical projection area is understood as the support area of the base;

[0061] The support assembly 2 includes: a first support member 21, a lifting rod 22, and a second support member 23 that are connected in sequence; the lifting rod 22 is detachably connected between the first support member 21 and the second support member 23, and the second support member 23 can be detachably connected to the first support member 21;

[0062] The first support member 21 is installed on the first base 11, and the second support member 23 is installed with a display screen 3.

[0063] In the above technical solution, this multifunctional screen base can be in a mobile screen mode ( Figure 1 as shown) and a desktop display mode (such as Figure 2Switching back and forth between the states shown in the figure; when the multi-functional screen base is in the mobile screen mode, the first base 11 is installed on the second base 12, the first support member 21 is installed on the first base 11, the first support member 21 is sequentially connected to the lifting rod 22 and the second support member 23 (the second support member 23 is equipped with the display screen 3), and the universal wheels on the lower bottom plate of the second base 12 are used for convenient movement; when it is necessary to switch from the mobile screen mode to the desktop display mode, the lifting rod 22 between the first support member 21 and the second support member 23 is removed, the second support member 23 is installed on the first support member (21), and the first base 11 and the second base 12 are separated (the second base 12 is removed), and then the desktop display mode is formed (as Figure 2 shown in the figure); of course, to switch from the desktop display mode to the mobile screen mode, only the corresponding components (the second base 12, the lifting rod 22) need to be reinstalled.

[0064] In comparison with the prior art in this technical solution, this technical solution utilizes the buckle mechanism 4 to enable the detachable setting between the first base 11 and the second base 12, the detachable connection of the lifting rod 22 between the first support member 21 and the second support member 23, and the detachable connection of the second support member 23 to the first support member 21; this enables the base to add the function of the desktop display mode and can also complete the switching back and forth between the mobile screen mode ( Figure 1 shown in the figure) and the desktop display mode (as Figure 2 shown in the figure).

[0065] To optimize the above technical solution, as Figures 3 - 7 shown in the figure, the first support member 21 includes: the first support rod 211 and the second support rod 212; the second support member 23 includes: the third support rod 231;

[0066] The first support rod 211 is arranged on the first base 11, and the first end of the second support rod 212 is detachably sleeved on the outer wall of the first support rod 211; the length of the second support rod 212 is greater than the length of the first support rod 211;

[0067] The second end of the second support rod 212 is detachably sleeved on the outer wall of the first end of the lifting rod 22, the first end of the third support rod 231 is detachably sleeved on the outer wall of the second end of the lifting rod 22 or the outer wall of the first support rod 211, and the second end of the third support rod 231 is installed with the display screen 3.

[0068] In the above technical solution, when the multi-functional screen base is in the mobile screen mode, the first support rod 211, the second support rod 212, the lifting rod 23 and the third support rod 231 are sequentially connected; when in the desktop display mode, the lifting rod 23 is removed (as Figures 3 to 4 shown in the figure), and then the first base 11 is removed from the second base (asFigures 5 to 6 as shown in the figure), and then the third support rod 231 is installed on the first support rod 211 (as Figure 7 shown); through the above settings, the quick switching between the mobile screen mode and the desktop display mode can be realized.

[0069] To further optimize the above technical solution, as Figures 1 - 8 shown, it further includes: an adjusting screw 5;

[0070] Between the first ends of the first support rod 211 and the second support rod 212, between the second end of the second support rod 212 and the first end of the lifting rod 22, between the second end of the lifting rod 22 and the first end of the third support rod 231, and / or between the first end of the third support rod 231 and the first support rod 211 are fastened by the adjusting screw 5.

[0071] It should be noted that the number of the adjusting screws 5 is three. Using the adjusting screws 5 for fixation improves the assembly efficiency, and the adjusting screws 5 make the connection structure more firm.

[0072] In some solutions, as Figure 8 a platform is milled at one end of the first support rod 211 away from the first base, and the milled platform is used to connect and fix the second support rod 212 or the third support rod 231; it should also be noted that the structure between each of the first support rod 211, the second support rod 212, the lifting rod 22, and the third support rod 231 is also as Figure 8 shown (that is, a platform is milled on one rod, and the other rod is sleeved on the outer surface of the platform); it should be noted that the platform is a cylindrical structure.

[0073] In this technical solution, it further includes: a buckle mechanism 4 installed on the second base 12;

[0074] The second base 12 detachably installs the first base 11 through the buckle mechanism 4, and the buckle mechanism 4 can quickly disassemble and assemble between the first base 11 and the second base 12.

[0075] To optimize the above technical solution, as Figures 9 - 14 shown, the buckle mechanism 4 includes: two elastic mechanisms 41 and a driving rod 42;

[0076] Both of the two elastic mechanisms 41 and the driving rod 42 are arranged on the second base 12, and the two elastic mechanisms 41 are symmetrically arranged with respect to the driving rod 42;

[0077] Each elastic mechanism 41 includes a locking block 411, and the first base 11 is provided with two locking grooves 111 corresponding to and cooperating with the locking block 411 one by one;

[0078] The driving rod 42 can push the locking blocks 411 to move towards each other, so that the locking blocks 411 disengage from the corresponding locking grooves 111; the elastic mechanism 41 can provide an elastic restoring force to make the locking blocks 411 move away from each other, and can make the locking blocks 411 lock with the corresponding locking grooves 111.

[0079] In the above technical solution, when the multi-functional screen base needs to be switched to the desktop display mode, the driving rod 42 is used to drive the locking blocks 411 to move towards each other (as Figure 12 shown, the arrows in the figure are the directions of movement towards each other), the locking blocks 411 disengage from the corresponding locking grooves 111 (that is, the first base 11 and the second base 12 disengage), and placing the first base 11 on the support surface can complete the switching of the desktop display mode; when the multi-functional screen base needs to be switched to the mobile screen mode, the locking groove 111 is aligned and snapped into the locking block 411, and under the action of the restoring force provided by the elastic mechanism, the locking blocks 411 move away from each other, and the locking blocks 411 lock with the corresponding locking grooves 111, and the switching of the desktop display mode can be completed; of course, it should be noted that when switching between the desktop display mode and the mobile screen mode, the disassembly and assembly between the corresponding support components and the lifting rod are also involved.

[0080] Optimizing the above technical solution, as Figure 12 and Figure 13 shown, the end corresponding to the first end of the driving rod 42 is an isosceles trapezoid structure;

[0081] Each locking block 411 has a block hypotenuse part 412 that is parallel and fitted with the waist hypotenuse part 422 of the driving rod 42, and the waist hypotenuse part 422 and the corresponding block hypotenuse part 412 can slide relative to each other.

[0082] In the above technical solution, through the setting of the waist hypotenuse part 422 and the block hypotenuse part 412, the driving rod 42 can complete the mutual switching between the initial position and the extrusion position; it should be noted that the movement directions of the waist hypotenuse part 422 and the block hypotenuse part 412 from the initial position to the extrusion position are as Figure 12 the corresponding arrows shown.

[0083] Optimizing the above technical solution, as Figures 9 - 10 shown, the buckle mechanism 4 further includes: a button 43;

[0084] The first end of the driving rod 42 is located between the elastic mechanisms 41, and the second end of the driving rod 42 abuts against the driving end of the button 43, and the elastic mechanism 41 provides an elastic restoring force to push the driving rod 42 back to the initial position;

[0085] The force-receiving end of the button 43 passes through the first base 11 and is located above the upper surface of the first base 11.

[0086] In the above technical solution, when it is necessary to separate the first base 11 and the second base 12, a force is applied to the force-receiving end of the button 43. Under the action of the force, the driving end of the button 43 squeezes the second end of the driving rod 42, thereby causing the driving rod 42 to move towards the elastic mechanism 4 and squeezing the elastic mechanism 4, so that the locking block 411 is disengaged from the corresponding locking groove 111; after the first base 11 is taken away from the second base 12, under the action of the elastic restoring force of the elastic mechanism 4, the driving rod 42 returns from the squeezed position to the initial position.

[0087] To optimize the above technical solution, as Figure 11 shown, a positive bevel protrusion 421 is provided at the second end of the driving rod 42, and the protruding direction of the positive bevel protrusion 421 faces the driving end of the button 43;

[0088] A reverse bevel 431 that cooperates with the positive bevel protrusion 421 in relative motion is provided at the driving end of the button 43;

[0089] Among them, the slope of the positive bevel protrusion 421 faces away from the first end of the driving rod 42, and the slope of the reverse bevel 431 faces the first end of the driving rod 42.

[0090] In the above technical solution, when a force is applied to the force-receiving end of the button 43 and the button 43 is squeezed downward, due to the cooperation of the positive bevel protrusion 421 and the reverse bevel 431, the driving rod 42 moves from the initial position to the squeezed position, causing the locking blocks 411 to move towards each other; after the first base 11 is taken away, under the action of the elastic restoring force of the elastic mechanism, the locking blocks 411 move away from each other, causing the driving rod 42 to return to the initial position.

[0091] In this technical solution, as Figures 12 - 13 shown, the elastic mechanism 41 further includes: a return spring 413 and a U-shaped bone position 414, and the return spring 413 provides an elastic restoring force;

[0092] The U-shaped bone position 414 is arranged on the second base 12;

[0093] The first end of the return spring 413 is connected to the closed end of the U-shaped bone position 414, the second end of the return spring 413 is connected to the first surface of the locking block 411, and the second surface of the locking block 411 can abut against the driving rod 42, and the locking block 411 can slide within the U-shaped bone position 414.

[0094] In the above technical solution, the driving force of the driving rod 42 and the elastic restoring force provided by the return spring 413 are used to complete the assembly and disassembly of the first base 11 and the second base 12, thereby completing the rapid switching between the mobile screen mode and the desktop display mode.

[0095] To further optimize the above technical solution, Figures 12 - 14As shown, the elastic mechanism 41 further includes: a limit plate 415 and a limit rod 416;

[0096] The limit rod 416 is arranged on the second base 12;

[0097] The limit plate 415 is arranged on the locking block 411, and the limit plate 415 is provided with a limit sliding rail 417 that cooperates with the limit rod 416. The length direction of the limit sliding rail 417 is parallel to the movement direction of the locking block 411.

[0098] In the above technical solution, the limit sliding rail 417 and the limit rod 416 are used to limit the locking block 411; preferably, the limit sliding rail 417 is an oblong through hole, and the length direction of the oblong through hole is parallel to the movement direction of the locking block.

[0099] The following further introduces this solution in combination with specific embodiments:

[0100] In this technical solution, in the mobile screen mode, if you want to switch to the desktop display mode, you need to loosen the adjusting screw 5 on the lifting rod 22 counterclockwise, and then the entire display can be taken out, as Figures 3 - 4 shown; after removing the host, loosen the adjusting screw 5 at the bottom again, so that the second support rod 212 is disengaged from the first base 11. After taking out the second support rod 212, press the button 43 on the second base 12 to pop out the first base 11 required in the display mode, as Figures 4 - 5 shown; finally, assemble the first base 11 and the third support rod 231, and tighten the adjusting screw 5 to complete the switching of the display mode; it should be noted that the first base 11 is a flat base and the first base 12 is a mobile base.

[0101] Furthermore, to achieve the switching function between modes, mainly a quick-release connection structure between the support rods and a quick-release mechanism between the flat base and the mobile base are required. So that users can easily switch between the mobile screen mode and the display mode. The quick-release between the support rod and the lifting rod uses the method of screw fastening, with a simple and reliable structure and convenient to screw. The quick-release structure between the flat base and the mobile base has a buckle mechanism inside the mobile base, which can conveniently buckle the flat base. When the unlocking switch is pressed, the sliding buckle mechanism will be unlocked, and then the flat base can be taken out.

[0102] Furthermore, the principle of the quick-release structure between the flat base and the mobile base is as Figures 9 - 10 shown; in the mobile screen mode, when the user presses the button 43, the reverse inclined surface 431 under the button 43 will push the front inclined surface protrusion 421 of the driving rod 42 to move to the right, as Figure 11 shown (the right direction is Figure 11to the right); after the drive rod 42 with a buckle moves to the right, the drive rod 42 will push the locking block 411 with a buckle. The locking block 411 itself is provided with a limiting slide rail 417 (the limiting slide rail 417 is limited on the screw posts of the moving base by two screws). The reset of the locking block 411 is realized by a reset spring 413. The locking block 411 is realized in the U-shaped bone position in the bone position on the moving base, as Figure 12 and Figure 13 shown; when the user removes the flat base and releases the button 43, the locking block 411 will reset under the action of the reset spring. The locking block 411 pushes the drive rod 42, and the drive rod 42 then pushes the button 43 to reset the button 43. If you want to change the base from the desktop display mode back to the mobile screen mode, it is the same principle and will not be elaborated here.

[0103] In this specification, the various embodiments are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.
