Abstract:
A linear actuator includes a telescoping sleeve (100). The telescoping sleeve (100) includes an inner sleeve (110), an intermediate sleeve (120) sheathing the inner sleeve (110) and an outer sleeve (130) sheathing the intermediate sleeve (120). A base (200) connected to the intermediate sleeve (120); a motor (300) arranged on the base (200); a reduction worm gear (400) pivoted on the base (200) and driven by the motor; a rotor worm (500) pivoted on the base (200) and engaged with the reduction worm gear (400); a rotor worm gear (800) pivoted on the base (200); a stator worm (700) inserted in the rotor worm gear (800) and connected to the outer sleeve (130); and a stator nut (900) connected to the inner sleeve (110) and engaged with the rotor worm (500) are arranged in the telescoping sleeve (100).
Abstract:
A linear actuator includes a housing (100), a base plate (200) disposed in the housing (100), and two actuating mechanisms (310, 320) disposed on the base plate (200) and received in the housing (100). Each actuating mechanism (310/320) comprises a motor (311/321), a transmission assembly (312/322), a screw rod (313/323), and a supporting block (314/324). Two motors (311, 321) and two transmission assemblies (312, 322) are disposed on the base plate (200). Two motors (311, 321) are kinetically connected to two assemblies (312, 322), respectively. One end of the screw rod (313/323) is connected to and rotated by the transmission assemblies (312/322). The other end of the screw rod (313/323) is screwed to the supporting block (314/324). Thus, two supporting blocks (314, 324) are driven to move in the housing (100).
Abstract:
An electrical adjustable table (10, 10′, 8) and its control method are disclosed. The control method of the electrical adjustable table includes following steps. Initialize an internal setting value or a user setting value. Enter a static status. Extend or shrink a table foot (11, 11′, 86) for adjusting the height of a table plate (13, 13′, 88) heading to a first direction according to an operation to a hand control device (25, 84). Stop adjusting the height of the table plate (13, 13′, 88) when a motion sensor unit is used and detects the table plate tilted during adjusting the height of the table plate. The method effectively prevents the table plate to keep lifting when the table plate hits an obstacle to avoid objects fallen, the obstacle damaged or malfunction of the electrical adjustable table.
