6. The wall hanging bracket according to claim 4, wherein the linkage assembly comprises a second link rotatably disposed at the rotation shaft, the upper slider and the lower slider rotatably disposed at upper and lower ends of the second link, respectively, the second link crossing the first link.

7. The wall mountable bracket according to claim 6, comprising a damping device disposed between the first link and the second link for slowing the support frame away from or toward the mount.

8. The wall hanging bracket according to claim 7, wherein the damping device is a gas spring, and two ends of the gas spring are respectively and rotatably arranged on the first connecting rod and the second connecting rod; when the power device drives the lower sliding block to slide along the lower sliding rail in the forward direction, the first connecting rod rotates around the rotating shaft in the forward direction, the second connecting rod rotates around the rotating shaft in the reverse direction, the supporting frame is far away from the fixed frame, and the gas spring is stretched to slow down the speed of the supporting frame far away from the fixed frame; when the power device drives the lower sliding block to slide reversely along the lower sliding rail, the first connecting rod rotates reversely around the rotating shaft, the second connecting rod rotates forwards around the rotating shaft, the supporting frame is close to the fixing frame, and the air spring is compressed to slow down the speed of the supporting frame close to the fixing frame.

9. The wall-mounted type bracket according to any one of claims 1 to 8, wherein the slide rails comprise a middle slide rail fixedly arranged in the middle of the fixing frame and side slide rails fixedly arranged at two sides of the fixing frame; the guide piece comprises a middle guide strip fixedly arranged in the middle of the support frame and side guide strips fixedly arranged on two sides of the support frame, and the middle guide strip is slidably arranged on the middle sliding rail; the side guide bars are slidably disposed on the side slide rails.

10. The wall-mounted type bracket according to claim 9, wherein the wall-mounted type bracket comprises two sets of bracket components, and the power device is fixedly arranged between the two sets of bracket components and used for driving the guide member to slide along the slide rail, so that the support frame is far away from or close to the fixed frame to drive the intelligent blackboard to ascend or descend.

11. Wall-hanging wisdom blackboard, its characterized in that includes:

an intelligent blackboard, and

the wall-mounted stand according to any one of claims 1 to 10, wherein the intelligent blackboard is fixedly mounted on the wall-mounted stand.
