Abstract: A fluid-floated conveying device includes a multi-channel space conversion cabin. An upper channel port is provided with a floating ball outlet gate which is communicated with a water pipe filled with a liquid. A side channel port is provided with a floating ball inlet gate communicated with the external atmosphere. A lower channel port is connected to a water storage pressure cylinder or a water discharging pipe. A floating ball carries articles and enters the cleared space conversion cabin from the side channel. The floating ball inlet gate of the side channel is closed, the cabin is filled with water, the floating ball outlet gate of the upper channel is opened, the floating ball rises and enters from the upper channel port, the communicated water pipe filled with the liquid, the water buoyancy enables the floating ball to rise, and the carried articles are conveyed to a receiving platform.

Abstract: An intelligent multifunctional accumulator includes a multi-pin intelligent controller, a signal emitter, a buzzer, a sensor and an accumulator with an enclosure with two layers. All the aforementioned devices are assembled inside the cavity on the back side of the top cover. Two positive terminals are set on the top surface of the accumulator enclosure. The two positive terminals can separately control the power of the engine and other electric appliances by a chip and two relays to attain an anti-theft function. The intelligent controller can be automatically locked after it is inserted into a controller box on the back side of the top cover, and cannot be taken out without the password signal of a car owner. The sensor can automatically detect the inner state of the accumulator, and the information of the state can be displayed by an LCD or sent out by using voice prompts.

Abstract: A backrest assembly having chambers for articles is configured with a U-shape main frame. The top of the main frame has a connecting bracket. The connecting mechanism is adjustably connected with a spacing block with a spring biased steel ball, a recess and a spring biased latch. The spacing block is connected to a top plate with a spring biased steel ball, a recess and a spring biased latch. The main frame is also attached with a backrest which has a chamber at the rear side as well. By this provision, the main frame can be directly or removably attached to the seat of the car. A TV set can be disposed with the chamber of the pillow and a video, game, or karaoke can be installed within the chamber of the backrest. The position of the pillow and the backrest can be readily adjusted to a desired position by the adjustable connection according to different requirements.
