Abstract
Description
Technical Field
[0001] This utility model relates to the field of monitor lifting bracket technology, specifically to an electromagnetic lifting bracket. Background Technology
[0002] Traditional LCD monitor stand structures use a coil spring to connect the monitor connector and the support frame, allowing the monitor to be flexibly adjusted in height along the support frame. Current technology involves manually moving the monitor up and down to adjust the height, which is inconvenient. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an electromagnetic lifting support.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An electromagnetic lifting bracket includes a support frame and a connector. The front end of the connector is connected to the back of a display, and the rear end of the connector is connected to a lifting sliding cavity inside the support frame via a sliding part. The sliding part at the rear end of the connector is connected to the inner wall of the support frame via a coil spring. Vertically arranged guide brushes are fixed on two opposite sides inside the lifting sliding cavity. A conductor is fixed on the sliding part of the connector, with its two ends slidingly contacting the two guide brushes. Magnets with opposite magnetic poles are fixed on two other opposite sides inside the lifting sliding cavity. A circuit control board is provided inside the base of the support frame, and the conductor is electrically connected to the circuit control board, which controls the magnitude and direction of the current in the conductor.
[0006] Furthermore, the outer side of the base of the support frame is provided with a control knob that is electrically connected to the circuit control board.
[0007] Furthermore, limit sensors are respectively provided at the upper and lower ends of the lifting sliding cavity.
[0008] This utility model adopts the above technical solution, adding electromagnetic induction and current design to the traditional lifting bracket structure. By using the principle of electromagnetic force generation, it optimizes the traditional manual lifting method to control the rise and fall of the monitor, thereby achieving the purpose of automated and intelligent control of the monitor's lifting.

[0014] like Figure 1-3 As shown, this utility model discloses an electromagnetic lifting bracket, including a support frame 1 and a connector 2. The front end of the connector 2 is connected to the back of the display 3, and the rear end of the connector 2 is connected to the lifting sliding cavity inside the support frame 1 through a sliding part. The sliding part at the rear end of the connector 2 is connected to the inner wall of the support frame 1 through a coil spring. The above structure allows the display 3 to slide along the lifting sliding cavity and suspend. The above structure is all prior art (such as the prior patent CN201921644624.1 - A vertical display bracket), and the specific structure and principle will not be described in detail.
[0015] This invention incorporates electromagnetic induction and current design into the traditional lifting support structure, optimizing the traditional manual lifting method through the principle of electromagnetic force generation. The specific structure is as follows:
[0016] Inside the lifting sliding cavity, vertically oriented guide brushes 4 are fixed on two opposite sides. A conductive body 5 is fixed on the sliding part of the connector 2, with its two ends slidably connected to the two guide brushes 4. On the other two opposite sides inside the lifting sliding cavity, vertically oriented magnets 6 are fixed, with opposite magnetic poles (one side is the N pole, the other the S pole). A circuit control board 7 is located inside the base of the support frame 1, and the conductive body 5 is electrically connected to the circuit control board 7, which controls the magnitude and direction of the current in the conductive body 5. Furthermore, a control knob 8 electrically connected to the circuit control board 7 is located on the outside of the base of the support frame 1.
[0017] To achieve limit positioning, limit sensors are installed at the upper and lower ends of the lifting sliding cavity.
[0018] 1. Working principle of this utility model: as follows Figure 4 As shown, the Ampere force F = BIL; B: magnetic induction intensity; I: electric force; L: current-carrying conductor strength.
[0019] 2. Traditional supports are in a state of weight balance (balanced internally by coil springs). This utility model controls the current by designing a control knob 8: a) When the knob is rotated clockwise, the current increases in the positive direction, F increases upward, and the support rises; b) When the knob is rotated counterclockwise, the current increases in the opposite direction, F increases downward, and the support falls; c) The current is 0 when the knob is in the middle.
[0020] 3. When the monitor 3 rises or falls to a certain position, turn the knob to the middle position (I=0) and the monitor 3 will stop.
[0021] 4. When the limit position is reached, the limit sensor (or the power supply sensor) will trigger I=0, and the display 3 will stop.
[0022] 5. Adjust the magnetic field strength and current according to different models and weights.
[0023] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
