4 is a view showing the configuration of the monitor lifting device of the electromagnetic lecture table according to an embodiment of the present invention.

Referring to this, the automatic lifting means 60 constituting the monitor lifting device of the electromagnetic lecture table according to an embodiment of the present invention exemplifies the hydraulic cylinder 30, which is only the hydraulic cylinder 30 It is not limited.

Like the known hydraulic cylinder, the hydraulic cylinder 30 has a fluid 62 and a spring 64 built in the hydraulic cylinder 30 to reduce the in / out impact when the cylinder rod 32 is drawn in and out. As the cylinder to be made, first and second check valves 61a and 61b are formed at the upper and lower circumferences of the hydraulic cylinder 30, respectively, and the small hydraulic pump 66 and the first and second check valves 61a, 61b) is connected by the 1st, 2nd delivery pipes 67a and 67b.

In addition, the monitor lifting device of the electromagnetic lecture table according to an embodiment of the present invention receives a touch signal from the rising touch sensor 52 and the falling touch sensor 54, the small hydraulic pump 66 is driven And control the first and second check valves 61a and 61b to automatically raise and lower the monitor 12 by controlling the movement of the fluid 62 inside the hydraulic cylinder 30 for the rising and falling. One control unit 68 is provided.

With reference to the accompanying drawings, the function and action of the monitor lifting device of the electromagnetic lecture table according to an embodiment of the present invention of the above configuration will be described in detail.

First, the monitor lifting device of the electromagnetic lecture table according to an embodiment of the present invention, the user moves the upper cover 8 provided on the upper surface of the electromagnetic lecture table 2 'to one side, the monitor 12 is the upper surface In the exposed state, when the lower end of the monitor 12 is pressed, the monitor 12 is lifted about the hinge 40 of the lower end.

In this state, since the sensor contact rod 50 provided at the lower end of the monitor 12 touches the rising touch sensor 52, the rising touch sensor 52 generates a rising signal. Then, the rising signal of the rising touch sensor 52 flows into the control unit 68. Then, the control unit 68 generates and opens an open control signal to the first check valve 61a and the second check valve 61b, and drives the small hydraulic pump 66 to the first check valve 61a. The fluid 62 leaked out through the second check valve 61b is introduced into the lower end of the hydraulic cylinder 30 again.

Then, the fluid introduced through the second check valve 61b pushes up the hydraulic cylinder rod 32 together with the restoring force of the spring 64, so that the upper end of the monitor 12 is raised at an angle.

At this time, the control unit 68 has a predetermined time for driving the small hydraulic pump 66 is set in advance in the internal memory (not shown) of the control unit 68 so that the small hydraulic pump 66 is driven only during the corresponding time. As a result, the angle of the monitor 12 can be adjusted. That is, by changing the time set in the controller 68, it is possible to adjust the rotation elevation angle of the monitor 12. Such time setting means (e.g., key operation means, etc.) will not be described.

On the other hand, when the monitor 12, which is lifted and rotated at an angle, is to be accommodated in the monitor seating recess 10 ', the user presses the upper end of the monitor 12 by hand, as opposed to when the monitor 12 is raised. Then, the upper end of the monitor 12 is rotated about the lower hinge 40 is lowered.

In this state, since the sensor contact rod 50 provided at the lower end of the monitor 12 touches the falling touch sensor 54, the falling touch sensor 54 generates a falling signal. Then, the falling signal of the falling touch sensor 54 is introduced into the control unit 68. Then, the controller 68 generates and opens an open control signal to the first check valve 61a and the second check valve 61b, and drives the small hydraulic pump 66 to the second check valve 61b. Through the fluid 62 in the lower end of the hydraulic cylinder 30 through the outside, and through the first check valve (61a) to be introduced back into the inner upper end of the hydraulic cylinder (30).

Then, the fluid introduced through the first check valve 61a pressurizes the hydraulic cylinder rod 32 while flowing into the upper end of the hydraulic cylinder 30, and the lower end of the hydraulic cylinder rod 32 Since the spring 64 is pressed and the upper end of the monitor 12 connected to the hydraulic cylinder rod 32 is lowered, the monitor 12 is accommodated in the monitor seating groove 10 ′.

Therefore, the monitor lifting device of the electromagnetic lecture table according to the embodiment of the present invention can raise and lower the monitor 12 automatically when the user generates a minute pressing force, thereby increasing the convenience, and the monitor 12 is raised. And since it is naturally descending without falling impact to improve the durability of the monitor 12, it can add the luxury of the device.

On the other hand, the monitor lifting device of the electronic lecture table according to an embodiment of the present invention is not shown, but does not have the lifting and lowering touch sensor (52, 54), the separate lifting operation buttons (not shown) It is provided on the upper plate 6 of the electronic table, and the monitor 12 can be raised and lowered by the raising and lowering operation signals of the raising and lowering operation buttons (not shown).

The configuration of the monitor lifting device of the electromagnetic lecture table according to the embodiment of the present invention can accommodate the monitor 12 in the monitor seating groove 10 'without directly pressing the monitor 12 in a predetermined direction. In addition, since the monitor 12 can be raised at an angle from the monitor seating groove 10 ', convenient use is possible.

On the other hand, the monitor lifting device of the electromagnetic lecture table according to an embodiment of the present invention is not limited only to the above embodiment, but various modifications can be made within the scope without departing from the technical gist.

As described above, the monitor lifting device of the electronic lecture table according to the present invention can raise and lower the monitor automatically when the user generates a minute pressing force, thereby increasing the convenience, the monitor is naturally raised and lowered without impact Being stronger increases the durability of the monitor and adds luxury to the device.
