Description

Technical Field

[0001] The present application relates to the field of home appliance technology, for example, to a display stand and a mobile smart screen. Background Art

[0002] At present, televisions are often used in fixed locations and are not convenient to move, while tablet screens are small and not efficient enough. The emergence of mobile smart screens solves these problems.

[0003] Most of the existing mobile smart screens on the market use a vertical lifting method that goes straight up and down, that is, the angle of the horizontal bar in the support frame relative to the vertical bar remains unchanged. This greatly reduces the adjustment angle range of the screen during use. And because the display is heavy and cantilevered, the longer the horizontal bar, the higher the strength requirement of the structural parts at the connection between the horizontal bar and the vertical bar, and the higher the assembly process requirements.

[0004] Therefore, it can be seen that how to increase the angle adjustment range of the screen, reduce the structural strength requirements at the connection between the horizontal rod and the vertical rod, and reduce the assembly process requirements have become problems that need to be urgently solved by technical personnel in this field.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The embodiments of the present disclosure provide a display stand and a mobile smart screen to solve the problem that when the horizontal bar and the vertical bar are connected, the strength requirements of the structural parts at the connection between the horizontal bar and the vertical bar are higher, and the requirements for the assembly process are higher.

[0008] In some embodiments, the display bracket includes: a vertical pole, a load-bearing rotating assembly, a horizontal rod and a rotating connector. The load-bearing rotating assembly is arranged at the upper end of the vertical pole; one end of the horizontal rod is connected to the load-bearing rotating assembly; and the rotating connector is arranged at the other end of the horizontal rod for connecting the display.

[0009] In some embodiments, the mobile smart screen includes: the display stand of the above embodiment.

[0010] The display stand and mobile smart screen provided by the embodiments of the present disclosure can achieve the following technical effects:

[0011] A load-bearing rotating assembly is arranged between the vertical pole and the horizontal pole, so that the horizontal pole can rotate relative to the vertical pole. At the same time, the horizontal pole and the display are connected by a rotating connector. When the angle of the display is adjusted, the display and the horizontal pole, as well as the horizontal pole and the vertical pole can rotate, which effectively improves the angle adjustment range of the display screen and makes the adjustment more flexible. At the same time, the use of the load-bearing rotating assembly can effectively share the gravity borne on the horizontal pole, thereby reducing the force strength between the vertical pole and the horizontal pole. While maintaining the horizontal pole with sufficient length, the stability of the overall structure is improved, and the requirements for the assembly process are reduced.

[0035] Combination Figure 1-3 As shown, the embodiment of the present disclosure provides a display stand, comprising: a vertical pole 100, a load-bearing rotating assembly 200, a horizontal bar 300 and a rotating connector 400. The load-bearing rotating assembly 200 is arranged at the upper end of the vertical pole 100; one end of the horizontal bar 300 is connected to the load-bearing rotating assembly 200; the rotating connector 400 is arranged at the other end of the horizontal bar 300, and is used to connect a display 500.

[0036] By using the display bracket provided by the embodiment of the present disclosure, a load-bearing rotating assembly 200 is arranged between the vertical pole 100 and the cross bar 300, so that the cross bar 300 can rotate relative to the vertical pole 100, and at the same time, the cross bar 300 and the display 500 are connected by a rotating connecting piece 400. When the angle of the display 500 is adjusted, the display 500 and the cross bar 300, as well as the cross bar 300 and the vertical pole 100 can be rotated, which effectively improves the angle adjustment range of the display 500 and makes the adjustment more flexible. At the same time, the load-bearing rotating assembly 200 can effectively share the gravity borne on the cross bar 300, thereby reducing the force strength between the vertical pole 100 and the cross bar 300. While maintaining the cross bar 300 with a sufficient length, the stability of the overall structure is improved, and the requirements for the assembly process are reduced.

[0037] Optionally, the pole 100 is a liftable and telescopic structure. In this way, the height of the fixed display 500 can be adjusted through the liftable and telescopic structure of the pole 100, and the position adjustment of the display 500 is more flexible, which improves the convenience of user use.

[0038] It can be understood that the lifting and telescopic structure can be that the vertical pole 100 itself adopts the form of a sleeve to perform lifting and adjusting. Its specific structure is well known to those skilled in the art and will not be described in detail here.

[0039] Combination Figure 4-6As shown, optionally, the load-bearing rotating assembly 200 includes: a slide bar 201, a spring 202, a sliding sheet 203, a crank 204 and a connecting rod 205. The slide bar 201 is provided with a slider 206 at one end and abutting block 207 at the other end; the spring 202 is sleeved on the slide bar 201 and is located between the slider 206 and the abutting block 207; the sliding sheet 203 is provided with a slide groove 208, which is clamped on the slide bar 206, and one end of the slide bar 203 is provided with a rotating shaft 209, and the other end abuts against one end of the spring 202, wherein the rotating shaft 209 is connected to the cross bar 300; the crank 204 is fixedly arranged on the rotating shaft 209; one end of the connecting rod 205 is rotatably connected to the slider 206, and the other end is rotatably connected to the crank 204. In this way, the load-bearing rotating assembly 200 is provided with a rotating shaft 209 for connecting the cross bar 300. When the cross bar 300 is adjusted to rotate, the rotating shaft 209 is driven to rotate, and the crank 204 is further driven to rotate along with the rotating shaft 209. One end of the rotating shaft 209 is connected to the connecting rod 205, and the other end is rotatably connected to the sliding bar 201. Under the rotation of the crank 204, the distance between the other end of the sliding bar 201 and the rotating shaft 209 can be changed. Since the rotating shaft 209 is connected to the sliding sheet 203, during the rotation of the crank 204, the sliding sheet 203 03 and the abutment block 207 will change, thereby compressing the spring 202 mounted on the slide bar 201, and utilizing the spring 202 to buffer the force generated by the rotation of the rotating shaft 209, thereby reducing the stress on the cross bar 300 when supporting the display 500, improving the structural stability of the connection between the cross bar 300 and the vertical bar 100, reducing the force strength between the vertical bar 100 and the cross bar 300, and improving the stability of the overall structure while maintaining the cross bar 300 of sufficient length, thereby reducing the requirements for the assembly process.

[0040] Optionally, the slide bar 201 is a cylindrical metal bar, and the spring 202 is sleeved on the slide bar 201, and its inner diameter is equal to the outer diameter of the slide bar 201, or its inner diameter is greater than the outer diameter of the slide bar, and the difference between its inner diameter and the outer diameter of the slide bar does not exceed 2 mm. In this way, the inner diameter of the spring 202 is close to the outer diameter of the slide bar 201, reducing the gap between the two, avoiding the spring 202 from shaking relative to the slide bar 201 during the compression and extension process along the slide bar 201, and improving the stability of the compression and extension of the spring 202.

[0041] Optionally, the outer side of the slide bar 201 is coated with a copper layer. In this way, the outer side of the slide bar 201 is coated with a copper layer, and the wear resistance and lubrication effect of copper itself can be used to reduce the relative sliding between the spring 202 and the slide bar 201, avoid friction damage, and increase the service life.

[0042] Optionally, the sliding sheets 203 are arranged in pairs, and are respectively located on both sides of the sliding rod 201. The sliding blocks 206 penetrate the sliding rod 201 and protrude on both sides of the sliding rod 201. The sliding grooves 208 on the two sliding sheets 203 are respectively clamped on the protruding ends of the sliding blocks 206. In this way, the sliding sheets 203 are arranged in pairs on both sides of the sliding rod 201, and the sliding sheets 203 and the sliding rod 201 are more stable when they move relative to each other, making the overall structure more stable.

[0043] Optionally, the sliding piece 203 is rotatably connected to the rotating shaft 209. In this way, the sliding piece 203 and the rotating shaft 209 are relatively rotatably connected, so that the sliding piece 203 can be driven to move up and down during the lifting and lowering movement of the rotating shaft 209 without affecting the rotation of the rotating shaft 209.

[0044] Optionally, a circular slot is provided on the sliding sheet 203, and the end of the rotating shaft 209 passes through the circular slot and is limited to rotate in the circular slot. In this way, the sliding sheet 203 can be stably fixed on the rotating shaft 209 without affecting the rotation of the rotating shaft 209, and the linkage process between the rotating shaft 209 and the sliding sheet 203 is more stable.

[0045] Optionally, the crank 204 is arranged perpendicular to the rotating shaft 209 and fixedly arranged on the side wall of the rotating shaft 209. In this way, the rotating shaft 209 can better convert the rotation of the rotating shaft 209 into the movement of the crank 204 during the rotation process, thereby better driving the movement of the sliding rod 201 relative to the sliding sheet 203.

[0046] Optionally, the crank 204 and the rotating shaft 209 are an integral structure, so that the connection between the crank 204 and the rotating shaft 209 is more stable and reliable, and the rotating shaft 209 and the crank 204 are easier to produce, thereby reducing the overall production cost.

[0047] Optionally, the crank 204 is connected to the center of the rotating shaft 209. In this way, the crank 204 can be more stably rotated along the rotating shaft 209, better drive the relative movement between the sliding sheet 203 and the sliding rod 201, and improve the stability of the overall structural movement.

[0048] Optionally, the connecting rod 205 is a double-layer structure, one end of which is clamped at one end of the crank 204 and is rotatably connected to the crank 204, and the other end is clamped at both sides of one end of the slide bar 201 and is rotatably connected to the sliders 206 on both sides of the slide bar 201. In this way, the connecting rod 205 with a double-layer structure can effectively improve the stability of the connection between the connecting rod 205 and the crank 204 and the connecting rod 205 and the slide bar 201.

[0049] Optionally, a hollow groove 210 is provided in the rotating shaft 209, and a connecting rod 211 is provided at one end of the cross bar 300, and the connecting rod 211 can be movably inserted into the hollow groove 210. In this way, the cross bar 300 and the rotating shaft 209 are connected through the connecting rod 211, so that the rotating shaft 209 and the cross bar 300 can be more stably and reliably connected.

[0050] Combination Figure 7 As shown, optionally, the connecting rod 211 is slidably arranged on the cross bar 300. In this way, the connecting rod 211 can be slidably connected relative to the cross bar 300, and then the position of the connecting rod 211 relative to the cross bar 300 is adjusted, and the distance between the display 500 fixed by the cross bar 300 and the vertical pole 100 is adjusted, thereby improving the flexibility of adjusting the display 500 and making it more convenient for users to use.

[0051] Optionally, a sliding sleeve 212 is provided on the cross bar 300, and the connecting rod 211 is fixedly arranged on the sliding sleeve 212. In this way, by sleeve-arranging the sliding sleeve 212 on the cross bar 300, the stability of the connection between the connecting rod 211 and the cross bar 300 can be improved, and the sliding adjustment of the connecting rod 211 relative to the cross bar 300 can be facilitated.

[0052] Optionally, a locking structure is provided between the sliding sleeve 212 and the cross bar 300. In this way, the position of the sliding sleeve 212 relative to the cross bar 300 can be locked by the locking structure, thereby improving the stability of the relative position between the sliding sleeve 212 and the cross bar 300.

[0053] It can be understood that the locking structure can be a fixing screw that penetrates the sliding sleeve 212 and can abut against the cross bar 300. In this way, the relative position between the cross bar 300 and the sliding sleeve 212 can be better fixed, and the stability of the overall structure can be improved.

[0054] Optionally, a positioning plane 213 is provided on the side of the connecting rod 211, and the shape of the hollow groove 210 is adapted to that of the connecting rod 211. In this way, when the connecting rod 211 is inserted into the hollow groove 210, the positioning plane 213 can be used to maintain the connection rod 211 and the hollow groove 210 to be movable, but to avoid relative rotation between the two, thereby improving the relative fixation stability between the connecting rod 211 and the hollow groove 210.

[0055] Optionally, a locking screw hole 214 penetrating the hollow groove 210 is provided on the side of the rotating shaft 209, and a fixing wire 215 is provided in the locking screw hole 214. In this way, the fixing wire 215 passes through the locking screw hole 214 to abut and fix the connecting rod 211 inserted in the hollow groove 210, thereby improving the stability of the relatively fixed connection between the connecting rod 211 and the rotating shaft 209.

[0056] Optionally, one of the abutment block 207 and the sliding sheet 203 is fixedly connected to the vertical pole 100. In this way, one of the abutment block 207 and the sliding sheet 203 can be fixedly connected to the vertical pole 100, and the other can be movable; when the abutment block 207 is fixedly connected to the vertical pole 100, when the angle of the display 500 needs to be adjusted, the cross bar 300 can be rotated to drive the rotation shaft 209 to rotate, and when the rotation shaft 209 rotates, the crank 204 and the connecting rod 205 can be driven to move, and the distance between the rotation shaft 209 and the abutment block 207 can be changed. In the case of the compression spring 202 buffering pressure, the sliding sheet 203 and the rotation shaft 209 can also be moved in the vertical direction relative to the abutment block 207, so that the rotation shaft 209 can be raised and lowered, and the height of the display 500 can be finely adjusted when the angle is changed, which is more convenient for users to use and improves the flexibility of users to use; when the sliding sheet 203 is fixedly connected to the vertical pole 100, the cross bar 300 can be rotated to drive the rotation shaft 209 to rotate, and the crank 204 and the connecting rod 205 can be driven to move when the rotation shaft 209 rotates, and the distance between the rotation shaft 209 and the abutment block 207 can be changed. When the rods 100 are fixedly connected, the rotating shaft 209 is driven to rotate by rotating the cross bar 300, which will also further drive the crank 204 and the connecting rod 205 to move, thereby changing the distance between the rotating shaft 209 and the abutment block 207. While keeping the position of the rotating shaft 209 unchanged, the abutment block 207 can be moved closer to the rotating shaft 209. The compression spring 202 between the sliding sheet 203 and the abutment block 207 is used to buffer the pressure, thereby reducing the excessive pressure at the rotating position caused by the weight of the display 500 when adjusting the display 500, reducing the force intensity at the rotating position, and while maintaining the cross bar 300 with a sufficient length, improving the stability of the overall structure, reducing the requirements for the assembly process, and improving the feel of the display 500 when the display 500 is rotationally adjusted.

[0057] Optionally, the abutment block 207 is fixedly connected to the vertical pole 100, and the sliding piece 203 can slide relative to the vertical pole 100. In this way, when the abutment block 207 is fixedly connected to the vertical pole 100, the sliding piece 203 can slide relative to the vertical pole 100, so that the sliding piece 203 can slide stably relative to the vertical pole 100, thereby better enabling the sliding piece 203 to slide relative to the vertical pole 100, compressing the spring 202, and adjusting the height of the rotating shaft 209, thereby fine-tuning the lifting and lowering of the display 500 while it rotates.

[0058] Optionally, the sliding piece 203 is fixedly connected to the vertical pole 100, and the abutment block 207 is slidable relative to the vertical pole 100. In this way, when the sliding piece 203 is fixedly connected to the vertical pole 100, the abutment block 207 is slidable relative to the vertical pole 100, so that the abutment block 207 can slide stably along the vertical pole 100, thereby better utilizing the space between the sliding piece 203 and the abutment block 207 to compress the spring 202, buffer the rotation pressure, and improve the stability of the overall structure.

[0059] Combination Figure 8-9As shown, optionally, a first movable connecting member 216 is provided between the abutment block 207 and the vertical pole 100 , and a second movable connecting member 217 is provided between the sliding sheet 203 and the vertical pole 100 . In this way, the abutment block 207 and the vertical pole 100 can be fixed or released by the first movable connection member 216, and the sliding piece 203 and the vertical pole 100 can be fixed or released by the second movable connection member 217. When only the angle of the cross bar 300 relative to the vertical pole 100 needs to be adjusted, the sliding piece 203 and the vertical pole 100 can be fixed by the second movable connection member 217, and the first movable connection member 216 can be used to fix the abutment block 207 and the vertical pole 100. When the height of the cross bar 300 is fine-tuned while adjusting the angle of the cross bar 300 relative to the vertical pole 100, the abutment block 207 and the vertical pole 100 are fixed by the first movable connection member 216, and the second movable connection member 217 can release the fixation of the sliding piece 203 and the vertical pole 100, so that the sliding piece 203 can slide relative to the vertical pole 100, and the height direction can be properly adjusted when the rotating shaft 209 rotates.

[0060] Optionally, the first movable connecting member 216 includes: a first plug hole 218, a second plug hole 219 and a plug-in 220. The first plug hole 218 is provided on the vertical pole 100 and passes through the side wall of the vertical pole 100; the second plug hole 219 is provided on the abutment block 207 and can correspond to the first plug hole 218; the plug-in 220 can be inserted into the first plug hole 218 and the second plug hole 219 at the same time when the first plug hole 218 and the second plug hole 219 correspond to each other, so as to fix the abutment block 207 and the vertical pole 100. In this way, when the plug-in 220 passes through the first plug hole 218 and the second plug hole 219 at the same time, the stability of the fixation between the abutment block 207 and the vertical pole 100 can be more stably improved, and the force bearing capacity of the connection position between the two can be improved.

[0061] Optionally, the second movable connecting member 217 has the same structure as the first movable connecting member 216. In this way, the stability of the connection between the sliding piece 203 and the vertical rod 100 can also be improved, so that the sliding piece 203 and the vertical rod 100 can maintain a higher load-bearing capacity when they are relatively fixed, thereby improving the overall structural strength.

[0062] Optionally, the crossbar 300 is arranged in parallel with the crank 204. In this way, the rotation of the crank 204 can be synchronized with the angle adjustment of the crossbar 300, and the rotation of the crank 204 is better driven by the rotation of the crossbar 300.

[0063] Optionally, the crossbar 300 and the crank 204 face the same side of the rotation axis 209. In this way, when the crossbar 300 is rotated downward for adjustment, the crank 204 is adjusted downward synchronously, driving the connecting rod 205 to move, so that the distance between the abutment block 207 and the rotation axis 209 increases, thereby driving the crossbar 300 to be fine-tuned upward. Conversely, when the crossbar 300 is rotated upward for adjustment, it can drive the crossbar 300 to be fine-tuned downward on the vertical pole 100, which is more in line with the user's visual experience as a whole and improves the flexibility of overall adjustment.

[0064] Combination Fig.10 As shown, optionally, a slot 101 is provided at the upper end of the vertical pole 100, and the load-bearing rotating assembly 200 is arranged in the slot 101. In this way, it is convenient to assemble and connect the load-bearing rotating assembly 200 and the slot 101, and the load-bearing rotating assembly 200 is used to improve the bearing force of the rotational connection between the connecting rod 211 and the vertical pole 100.

[0065] Optionally, the slot 101 is cylindrical, the abutment block 207 is also cylindrical, and the inner diameter of the slot 101 is the same as the outer diameter of the abutment block 207. In this way, the relative sliding between the abutment block 207 and the slot 101 is facilitated, and the stability of the abutment block 207 movement is improved.

[0066] Optionally, the inner wall of the slot 101 and the sliding sheet 203 are connected via a sliding structure 102. In this way, the sliding sheet 203 can slide more stably along the slot 101 through the sliding structure 102, thereby improving the sliding stability of the sliding sheet 203.

[0067] Combination Fig.11 As shown, optionally, the sliding structure 102 includes: a first limiting protrusion 103, which is vertically arranged on the inner side wall of the slot 101; a second limiting protrusion 104, which is vertically arranged on the inner side wall of the slot 101 and parallel to the first limiting protrusion 103, and the sliding piece 203 is limited between the first limiting protrusion 103 and the second limiting protrusion 104, and slides along the vertical direction. In this way, the sliding piece 203 is limited to slide between the first limiting protrusion 103 and the second limiting protrusion 104, so as to avoid the sliding piece 203 from moving during the movement process, and improve the stability of the overall sliding piece 203 relative to the vertical rod 100.

[0068] Optionally, abutment surface 105 is provided at the bottom of slot 101 to limit the position of abutment block 207. In this way, the position of abutment block 207 can be limited, and when abutment block 207 contacts abutment surface 105, the load-bearing capacity of abutment block 207 can be increased, and the position of the whole load-bearing rotating assembly 200 can be better fixed by fixing abutment block 207.

[0069] Combination Fig.11As shown, optionally, a through slot 106 is provided on the vertical pole 100, and one end of the cross bar 300 passes through the through slot 106 and is connected to the load-bearing rotating assembly 200. In this way, one end of the cross bar 300 passes through the through slot 106 and is connected to the load-bearing rotating assembly 200 in the vertical pole 100, so that when the cross bar 300 is connected to the vertical pole 100, the rotation of the cross bar 300 relative to the vertical pole 100 is avoided, and the relative rotation between the cross bar 300 and the vertical pole 100 is maintained.

[0070] Optionally, the through slot 106 is a vertical strip structure. In this way, the through slot 106 is prevented from obstructing the cross bar 300, so that the cross bar 300 can be fine-tuned up and down on the vertical pole 100, thereby improving the convenience of overall adjustment.

[0071] Optionally, the connecting rod 211 on the crossbar 300 passes through the through slot 106 and is connected to the load-bearing rotating assembly 200, and the width of the through slot 106 is the same as the diameter of the connecting rod 211. In this way, by setting the width of the through slot 106 to be the same as the diameter of the connecting rod 211, the connecting rod 211 can be kept stable during the up and down movement of the connecting rod 211 along the through slot 106, and the connecting slot 101 can be prevented from being offset left and right.

[0072] Optionally, the rotating connector 400 is a damping rotator. In this way, there is a damping force when the angle between the display 500 and the crossbar 300 is adjusted, so that the display 500 can stop at any angle when the angle is adjusted, and the flexibility and convenience of adjusting the display 500 is better maintained.

[0073] It can be understood that the damping rotator refers to a rotating structure having a damping force when rotating, so that the rotation can remain at any position. Its specific structure is a well-known technology for those skilled in the art and will not be described in detail here.

[0074] In some embodiments, the mobile smart screen includes: the display stand of the above embodiment.

[0075] The mobile smart screen provided by the embodiment of the present disclosure is adopted, by setting the display bracket of the above embodiment on the mobile smart screen, and by setting the load-bearing rotating assembly 200 between the vertical pole 100 and the cross bar 300, the cross bar 300 can be rotated relative to the vertical pole 100, and the cross bar 300 and the display 500 are connected by a rotating connector 400. When the angle of the display 500 is adjusted, the display 500 and the cross bar 300, as well as the cross bar 300 and the vertical pole 100 can be rotated, which effectively improves the angle adjustment range of the display 500 and makes the adjustment more flexible. At the same time, the load-bearing rotating assembly 200 can effectively share the gravity borne on the cross bar 300, thereby reducing the force strength between the vertical pole 100 and the cross bar 300. While maintaining the cross bar 300 with a sufficient length, the stability of the overall structure is improved, and the requirements for the assembly process are reduced.
