Description

A liquid crystal display electric lifting base

technical field

The utility model relates to a base of a liquid crystal display, in particular to an electric lifting base of a liquid crystal display.

Background technique

The existing liquid crystal display lifting base on the market has only manual lifting. As the size of the display becomes larger and larger, the addition of functions such as a touch screen at the same time causes the display to become heavier and heavier. Existing manual lifting base all seems more and more inconvenient in actual use. However, most of the electric lifting bases at the existing patent level are complex technical solutions that are difficult to realize, and cannot limit the lifting path.

Utility model content

Aiming at the deficiencies of the prior art, the present invention provides a technical proposal of an electric lifting base with convenient operation, simple structure and easy realization.

The technical solution adopted by the present invention for achieving the above object is: an electric lifting base of a liquid crystal display, comprising a button control board 9 connected to the stepping motor 2, controlling the stepping motor 2, the screw rod 3 connected to the stepping motor 2, and driving the nut 5 to carry out the lifting movement, the limit fixing part 4 is connected with the nut 5 by bolts, and the horizontal rotation of the nut 5 is limited; the two ends of the limit fixing part 4 are provided with columnar structures, placed in the guide grooves on both sides of the guide rail bracket 6, and the guide groove Cooperate to limit the lifting path; the stepper motor 2 is fixed on the lower end of the guide rail through the lower fixing part 8, and the lower fixing part 8 is bolted to the guide rail bracket 6; the limiting fixing part 4 is bolted to the display connector 1 to drive The display connector 1 moves up and down.

It also includes a chassis 10 for fixing the rail bracket 6 .

It also includes a button 11 corresponding to the key control panel 9 and placed on the chassis 10 to control the key control panel 9 .

It also includes that the decorative shell 7 is placed in the card slot of the chassis 10 .

The present invention has the following beneficial effects and advantages:

1. Utilizing the characteristic that the stepper motor will only rotate when the drive signal is given, and the positioning is accurate, the distance and speed of the screw screwing in and out of the nut can be accurately controlled.

2. The columnar structure of the limit fixing part is interspersed in the guide groove of the guide rail bracket, and can only move up and down. The limit fixture is fixed with the nut, and the nut is restricted by the limit fixture and moves up and down. Thus, the rotation of the stepping motor is changed into a lifting motion.

3. The guide rail bracket restricts the movement direction of the limit fixing part through its guide groove, and is fixed with the lower fixing part, and the lower fixing part is fixed with the stepper motor, so that the stepper motor is fixed under the inner guide groove of the guide rail bracket. Fixed with the chassis to erect the entire set of lifting mechanism, and cooperate with the decorative shell to play a beautifying effect.

Description of drawings

Fig. 2 is the overall appearance diagram of the utility model;

Among them, 1 is the display connector, 2 is the stepper motor, 3 is the screw, 4 is the limit fixing part, 5 is the nut, 6 is the guide rail bracket, 7 is the decorative shell, 8 is the lower fixing part, and 9 is the button control board , 10 are the chassis, and 11 are buttons.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figure 1, it is a structural diagram of the present utility model. Force is applied to the button control board 9 through the button 11 of the chassis 10, the button control board 9 is powered on, controls the stepper motor 2 to rotate forward or reversely, drives the screw rod 3 to rotate forward or reversely, and the screw rod 3 is screwed into the nut 5 or unscrew. Because the rotation of the nut 5 is limited by the guide rail bracket 6 through the limit fixture 4, the nut 5 and the limit fixture 4, the limit fixture 4 and the display connector 1, and the display connector 1 and the display are all fixed together, finally Drive the display up and down.

From the perspective of product structure, it mainly consists of display connector 1, stepper motor 2, screw rod 3, nut 5, limit fixing part 4, lower fixing part 8, guide rail bracket 6, button control board 9, chassis 10, button 11, The decorative shell consists of 7 parts.

1) Display connector 1: Connect to the display through the internationally accepted VESA hole.

2) Stepping motor 2: can rotate forward or reverse, and drive the screw 3 to rotate forward or reverse.

3) Screw 3: Driven by a stepping motor, it can be screwed in or out of the nut 5 to drive the nut 5 to move.

4) Limiting fixture 4: fixed together with the nut 5 and the display connector 1, and cooperates with the guide rail bracket 6 to prevent the nut 5 from rotating.

5) Nut 5: Under the action of the rotation of the screw rod 3, it moves up and down.

6) Guide rail bracket 6: the lower end is fixed on the chassis 10, and at the same time guides the limit fixture, the nut, and the display connector to move up and down.

7) Decorative shell 7: The decorative base can be designed with different appearance effects on the basis of ensuring the internal structure.

8) Lower fixing part 8: fix the stepper motor.

9) Button control board 9: power input, and control the stepper motor at the same time, so that the stepper motor rotates forward or reversely.

10) Chassis 10: fixed guide rail bracket, decorative shell, buttons and button control board.

11) Button 11: Operate the button control panel through the buttons to control the lifting of the base.

The working process is: by controlling the forward rotation and reverse rotation of the stepping motor 2, the driving screw 3 is screwed in and out of the nut 5. The limit fixture 4 is fixed to the nut 5 and the display connector 1, and the columnar structure of the limit fixture 4 is interspersed in the guide groove of the guide rail bracket 6 to prevent the rotation of the nut 5, so that the nut 5 drives the limit fixture 4 to connect with the display Part 1 does lifting motion. The display connector 1 is connected with the liquid crystal display, so as to drive the liquid crystal display to move up and down.
