A vehicle lift assembly having an input shaft, a first ball screw coupled to rotate with the input shaft, a ball screw nut coupled to a first bracket and configured to selectively move a lifting member based on rotation of the first ball screw, and a power unit coupled to the input shaft, the power unit having a wireless transponder and configured to be selectively powered based on wireless signals received by the transponder from a remote device.

An expandable car jack includes a vehicle lifting assembly with an upper lifting member, a lower lifting member mechanically coupled to the upper lifting member, and a lifting mechanism capable of moving the upper lifting member to a plurality of raised height positions. A base is coupled to the vehicle lifting assembly and includes a first base support member, a second base support member, and a base support coupler that is operable to selectively couple the first base support member to the second base support member in at least a first coupling position and a second coupling position. The base support coupler selectively mechanically maintains a parallel alignment and a perpendicular alignment of the first base support member and the second base support member when the base support coupler is in the first coupling position, allows the first base support member and the second base support member to freely move between the parallel alignment and the perpendicular alignment when the base support coupler is in the second coupling position, and remains mechanically coupled to at least the first base support member in the first and second coupling positions so that the first base support member cannot move with respect to the second base support member without a mechanical alteration to the base support coupler prior to moving either the first base support member or the second base support member.

A production method of a vehicle support device including: making a symmetrical thread structure by pressing on both sides of a round steel, to obtain a twin-screw rod; making a through hole in the steel block which the twin-screw rod can go through, and making internal threads in the through hole that match with the twin-screw rod by stamping to obtain an adjusting block; rotating the two adjusting blocks respectively along the ends of the twin-screw rod to the middle of the same so that the two adjusting blocks are mounted onto both sides of the twin-screw rod; making a movable frame, and fixing it with two adjusting blocks; and making a spanner and fixing it to one end or the middle of the twin-screw rod.

An apparatus for supporting a vehicle door, the apparatus comprising a base, a first support column mounted on the base, a lift device mounted on the first support column, the lift device comprising at least a first lift bar and a second lift bar each for engaging and together supporting a vehicle door and an actuator operatively coupled to the lift device. When actuated, the actuator imparts vertical movement to the lift device thereby imparting vertical movement to the vehicle door by way of the first lift bar and second lift bar. A second support column is mounted on the base, and the lift device is mounted on and guided by the first support column and the second support column. A load-bearing bridge member spans a space between the first support column and second support column above the base, and the actuator is mounted on the bridge member.

A wheel jack holder for a vehicle may include a holder base having at least one sliding member formed at each of first and second side portions of the holder base, whereby a wheel jack is configured for being placed on the holder base; and a pair of holder arms, each having a sliding rod formed at a first surface thereof, wherein the sliding rod is slidably inserted into a hole of the sliding member. The pair of holder arms may move away from each other when receiving force from the wheel jack to be fixed to a wheel rim of a wheel.
