An electric lifting platform retractable upon hitting an obstruction includes a lifting column, a platform, a controller, and a manipulator. The controller comprises a main control unit and a motor driving circuit. An output end of the main control unit is connected to the motor driving circuit. The electric lifting platform further includes a multi-axis sensor module for acquiring obstruction-hitting data of the platform. As the multi-axis sensor module is connected to an input end of the main control unit, the main control unit transmits a control signal to the motor driving circuit after processing the obstruction-hitting data, and the motor driving circuit controls the lifting column to execute a corresponding retracting movement.

A modularized fast assembly lift desk includes a preassembled module, a matched module and a clamping member. The preassembled module () includes a combined body formed by connection between a desktop platform and a transverse beam. The matched module includes a lift column including a motor housing. The clamping member includes a fixed connecting end and a movable squeezing end. When a user assembles the lift desk, the fixed connecting end of the clamping member is engaged with the preassembled module. The movable squeezing end of the clamping member is pressed to generate a squeezing force between the movable squeezing end and the motor housing. The motor housing and the preassembled module are fixedly connected to implement locking between the preassembled module and the matched module.

Modularized fast assembly lift desk and fast assembly method therefor

The present disclosure discloses an electric linear actuator, comprising: an electric motor, a transmission assembly in transmission connection with the electric motor, and a sleeve assembly in transmission connection with the transmission assembly, wherein the sleeve assembly comprises a main shaft, and a clutch device for implementing power connection or disconnection between the main shaft and the transmission assembly is provided between the main shaft and the transmission assembly, the clutch device comprising a ball clutch. The present disclosure solves the problem of poor smoothness of the existing electric linear actuators upon power connection or disconnection; besides, the present disclosure has a higher transmission efficiency and a longer service life.

A telescopic transmission assembly includes first and second stage rods, and first and second stage casings. The second stage rod is of a hollow structure having inner and outer surfaces and a through hole, the outer surface being provided with external threads, and the inner surface being devoid of threads. The first stage rod is disposed in the through hole to drive the second stage rod to rotate synchronously. The first and second stage rods are telescopically expandable or contractible relative to each other along an axial direction. The second stage casing sleeves over the first stage casing. The first and second stage casings have respectively first and second transmission nuts. The second and first stage rods are in a screw-thread fit with the first and second transmission nuts, respectively. The second stage rod is positioned with the first transmission nut in the axial direction in a rotatable manner.
