Limiting and guiding the mother and child slide rails, wherein the mother slide rails are arranged on both sides of the interior of the hollow cabinet body, and the child slide bars are arranged on the outer sides of the lifting frame body, and the limit child and mother slide rails are placed vertically;

The lifting traction part includes a lifting groove, a lifting threaded rod arranged in the lifting groove, and a threaded block arranged on the lifting threaded rod. The lifting groove is fixed on both sides of the interior of the hollow cabinet. Both sides are fixed at the top;

The end of the power output shaft and the top end of the lifting threaded rod are respectively provided with bevel gears that mesh with each other.

As a further improvement of the present invention, the upper and lower ends of the lifting groove are respectively provided with limit bearings for fixing the lifting threaded rod.

As a further improvement of the present invention, two cabinet doors are arranged in front of the hollow cabinet body, and a lift controller is arranged on one cabinet door, and the lift controller is electrically connected with the servo motor.

As a further improvement of the present invention, a limit switch is provided on the limit bearing, and the limit switch is electrically connected with the lift controller.

Compared with the prior art, the beneficial effects of the present invention are:

In the normal state of the present invention, the lifting frame body rises into the hollow cabinet body, which can be used by opening the cabinet door of the hollow cabinet body during use, or the lifting frame body can be realized by pressing the "up, stop and down" buttons of the lifting controller. Lift up and down for easy access to items.

The invention adopts the lifting and traction parts on both sides of the hollow cabinet body, and sets the servo motor on the top of the hollow cabinet body, so as to improve the appearance beauty of the product, and at the same time effectively use the space in the hollow cabinet body, so that the storage space of the lifting frame body is large. Durable, at the same time, the limit switch is used to automatically limit the up or down limit, intelligent self-commissioning, and large bearing capacity. The devices that realize the lifting function are all set in the lifting groove and have the function of anti-pinch.

Detailed ways

The present invention will now be further described in conjunction with the accompanying drawings and examples:

Referring to Figures 1 and 2, an intelligent automatic lifting cabinet includes a hollow cabinet body 1 embedded on the wall and a lifting frame body 2 placed in the hollow cabinet body. Two cabinet doors are provided in front of the hollow cabinet body, It also includes:

The servo motor 3 is arranged on the inner top surface of the hollow cabinet 1, and both ends are provided with power output shafts 4, and the two power output shafts are output synchronously;

Limiting and guiding the mother and child slide rails 5, wherein the mother slide rails are arranged on both sides of the interior of the hollow cabinet 1, and the child slide bars are arranged on the outer sides of the lifting frame body 2, and the limit child and mother slide rails are placed vertically, and the The sub-slider slides on the mother slide rail, wherein the mother slide rail is also provided with a second mother slide rail formed by the second stage addition, and the position-limiting sub-slider bar is arranged on the second mother slide rail, using The lifting frame is limited to lift up and down in the hollow cabinet to provide a stable lifting effect.

The lifting traction part includes a lifting groove, a lifting threaded rod 6 arranged in the lifting groove, and a threaded block 7 arranged on the lifting threaded rod. The lifting groove is fixed on both sides of the hollow cabinet 1. The threaded block 7 is connected to The top ends of the two sides of the lifting frame body 2 are fixed, and the end of the power output shaft 4 and the top end of the lifting threaded rod 6 are respectively provided with bevel gears 8 that mesh with each other.

The servo motor is driven by the power output shaft to drive the first bevel gear set at the end to rotate, and the conical surface of the first bevel gear is engaged with the conical surface of the second bevel gear of the lifting threaded rod, thereby driving the lifting threaded rod. of rotation. Since the thread on the lifting threaded rod is matched with the thread of the threaded block, the rotation of the lifting threaded rod realizes the up and down movement of the threaded block on the lifting threaded rod, thereby driving the lifting and lowering of the lifting frame body.

In this embodiment, the upper and lower ends of the lifting groove are respectively provided with limit bearings 9 for fixing the lifting threaded rod. The first limit bearing is arranged at the bottom end of the lifting groove and supports the bottom of the lifting threaded rod. The second limit bearing is arranged below the second bevel gear, and at the same time limits the lateral vibration of the lifting threaded rod.

In this embodiment, a lift controller is provided on the cabinet door, and the lift controller is provided with a control panel. The control panel includes three buttons of "up, stop, and down". It includes a forward and reverse rotation control circuit, which is electrically connected to the servo motor, and the forward and reverse rotation of the servo motor is controlled by the forward and reverse rotation control circuit. The purpose of reversal can be achieved. The three buttons of the control panel are electrically connected with the forward and reverse control circuit, and the lifting and lowering of the lifting frame can be realized by operating the buttons.

In this embodiment, a limit switch is provided on the limit bearing, the limit switch is electrically connected with the lift controller, and the limit switch defines the upward limit and the downward limit of the lift cabinet, so that the lift control The controller controls the servo motor to stop running.

In this embodiment, the bottom end of the sub-slider of the limit-guiding mother-sub-slider is provided with a buffer air support 10, and the servo motor is provided with an overload protection circuit. It will lead to faster descending speed. The self-rotation of the lifting threaded rod can provide a certain degree of load-bearing performance, and at the same time, it can realize the lifting more smoothly. When a stable and constant speed is set, the current and voltage of the servo motor will fluctuate more or less. The overload protection circuit will protect according to the current used by the servo motor, and cut off the power supply when the preload current value exceeds the range for protection. effect. In the process of descending, due to the effect of gravity or failure, the lift cabinet can buffer the descending limit and protect the descending limit through the buffer air support, thereby improving the safety performance.

To sum up, after reading the present document, those of ordinary skill in the art can make other corresponding transformation schemes without creative mental work according to the technical solutions and technical ideas of the present invention, which all belong to the protection scope of the present invention.
