This invention discloses a motion-sensing interaction system for a smart learning desk, including a height-adjustable desk with a notch in the tabletop and a flip-up tabletop within the notch. The front edge of the flip-up tabletop is hinged to the front edge of the height-adjustable desk. By flipping the rear edge of the flip-up tabletop forward, the tabletop tilts or flips forward to expose the notch. A writing board is installed at the notch, located below the flip-up tabletop. A first electric scroll and a second electric scroll are respectively located on the left and right sides of the writing board, with the handwritten scroll storage area of ​​the first electric scroll and the handwritten scroll collection area of ​​the second electric scroll facing each other, as well as the white paper roll storage area of ​​the first electric scroll and the white paper roll collection area of ​​the second electric scroll facing each other. This motion-sensing interaction system enables various human-computer interactions during calligraphy practice, including voice interaction, tactile interaction, and gesture interaction.

This utility model provides a tarpaulin control system and a vehicle. The tarpaulin control system includes: a motor drive module electrically connected to a tarpaulin drive motor, the motor drive module having multiple output states, including at least a first output state outputting a first preset current and a second output state outputting a second preset current, wherein the current direction of the first preset current is opposite to that of the second preset current; a power distribution module electrically connected to the motor drive module, the power distribution module being used to control the output state switching of the motor drive module; and a control module electrically connected to the power distribution module, the power distribution module controlling the output state of the motor drive module based on the control commands from the control module. This solution can realize the automatic unfolding and retraction of the tarpaulin, solving the technical problem of low work efficiency caused by the need for manual control of tarpaulins in related technologies.

The utility model discloses a construction site sectional material support frame belongs to the building engineering technical field. A construction site sectional material support frame, including the supporting leg, still include: set up a plurality of bracket on the supporting leg, wherein a plurality of bracket is arranged in longitudinal stack and is fixedly connected each other through the support plate, and the bracket fixedly connected in the most lower side is in the top of supporting leg, set up a plurality of support plate on the both sides of bracket, the utility model discloses through a plurality of layers bracket, support plate and the setting of limiting plate, can realize the layered storage management of different kinds sectional material, and sectional material limiting is placed on the shelf and is not easy to dump and pollution, greatly improved the security, can also reduce the floor space simultaneously, effectively improved the space utilization of construction site, through the setting of classification label, can mark the position, specification, quantity etc. information of each material layer area, can better manage and find the material of each layer, help to improve work efficiency.

This invention provides a transmission device and electric side pedal for an electric pedal, comprising: an active drive mechanism including a motor and an active linkage unit, the motor and the active linkage unit being drivenly connected; and a driven drive mechanism including a driven linkage unit, the active linkage unit and the driven linkage unit being respectively disposed at both ends of the pedal and both being fixedly connected to the pedal; characterized in that it further comprises: a connecting unit, the connecting unit being disposed between the motor and the active linkage unit, which can realize the connection and disconnection between the motor and the active linkage unit; the advantage is that the connecting unit is provided between the active linkage unit and the motor, which can connect or disconnect the motor and the active linkage unit. When the controller or motor is damaged, or the circuit is disconnected, or the electrical control part is not working, the pedal can no longer automatically unfold or retract. At this time, the connection between the motor and the active linkage unit can be disconnected through the connecting unit to realize manual reset or pull-out.
