Practical application of electric push rod with built-in planetary ball screw

Today's new electric push rod system includes a controller and a DC push rod. The left surface of the controller is fixedly equipped with a power interface, and a power module, a control module and a motor stall protection module are fixed inside the controller. The novel design is ingenious, convenient and practical. The controller can control a given signal voltage, automatically adjust the opening width of the ventilation window and adjust the ventilation volume. At the same time, the push rod will open the ventilation window to the maximum state under the power of the battery.

The invention relates to a novel electric push rod slider, which belongs to the field of electric push rods, and aims to stabilize the structure between two adjacent slider bodies, and is not easy to slide. The slider bodies comprise an internal thread tube and a hollow connector, the outer side of the internal thread tube extends horizontally, both sides of side plates are fixedly connected with an upper plate and a lower plate respectively, and an end plate is provided with a notch at one end of the lower plate, the length of which is equal to the length of the connecting plate, so that it is suitable for sliding connection devices on electric push rods.

The electric push rod with built-in planetary ball screw used now mainly includes a power device, a driven push rod and a power source. The power device includes a protective shell, a motor, a rotating main rod and a sleeve rod. The device includes a shell, a threaded roller screw and a threaded roller screw. The driving push rod is arranged on a connecting rod, and the distance sensing device is arranged in the protective shell. The device and the pressure sensing device greatly improve the sensitivity of the whole device and make the device more accurate and safe.

At present, the lubricating structure of electric push rod nut includes an inner tube sleeved outside the screw, a threaded moving nut on the screw for driving the inner tube shaft, and a guide sleeve for guiding the sliding between the inner tube and the outer tube, wherein the nut includes a plastic part and a metal part which are fixedly connected. Now, the product has reasonable design, novel structure and good lubricating effect, and lubricating oil can be injected into the push rod, so that the operation of the push rod is more stable and reliable, and the service life of the electric push rod is prolonged.
