Detailed ways

Specific Embodiment 1: This embodiment will be described with reference to Figures 1 to 5, a hidden computer desk, which includes a desktop board 1 and a hidden box 2 arranged under the desktop board 1, and the desktop board 1 is provided with a lifting opening And the lifting opening and the hidden box 2 are set up and down,

A cover plate 3 is arranged in the lifting port, and one end of the cover plate 3 is rotatably connected to the desktop board 1. A display lifting assembly and two sets of cover plate 3 lifting assemblies arranged side by side are arranged in the hidden box 2.

The display lifting assembly includes a lifting plate 4, two screw rod stepping motors 5 and two fixed mounts 6, and the two fixed mounts 6 are symmetrically fixed on the left and right inner sidewalls of the hidden box 2, and the two wires Rod stepper motors 5 are vertically fixed in the hidden box 2 through two fixed mounts 6 in one-to-one correspondence.

The cover plate 3 lifting assembly of each group all comprises spring 7, first slideway 8, second slideway 9, first push rod 10, second push rod 11 and L-shaped gusset 12, and described first slideway 8 is vertically fixed on the side wall of the hidden box 2, and the second slideway 9 is vertically fixed on the sidewall of the first slideway 8 on the fixed frame 6, and one end of the first push rod 10 It is rotationally connected with the L-shaped gusset 12 through the second push rod 11, the spring 7 is vertically arranged at the bottom of the hidden box 2, and the first push rod 10 slides up and down through the spring 7 and is arranged between the first slideway 8 and the Between the second slideway 9, and in the up and down sliding stroke of the first push rod 10, one side of the lifting plate 4 is pressed on the first push rod 10, and the L-shaped gusset 12 includes two end-to-end affixed Positioning plates, one of the positioning plates is parallel and fixed on the cover plate 3 , and the other end of the positioning plate away from the cover plate 3 is rotatably connected to the second push rod 11 .

The desk is supported by the drawer cabinet 13 and the support rod 14 arranged under the desktop board 1, the hidden box 2 is located between the drawer cabinet 13 and the support rod 14; the two ends of the lifting plate 4 are respectively sleeved on two screw rods On the screw mandrel of the stepping motor 5, the nut on the screw mandrel stepping motor 5 is affixed to the bottom end face of the lifting plate 4; , the desktop board 1 is also provided with a control switch, which controls the lifting of the screw mandrel stepping motor 5 through a wire.

In the up and down sliding stroke of the first push rod 10, one side of the lifting plate 4 is pressed on the first push rod 10, that is, when the lifting plate 4 rises, the first push rod 10 rises due to the elastic force of the spring 7. , so as to push the first push rod 10 to slide upward; when the lifting plate 4 rises beyond the sliding stroke of the first push rod 10, the cover plate 3 has been fully raised at this time, and the first push rod 10 is at the top limit position and stops. , the lifting plate 4 continues to rise until the computer monitor is fully raised; when the lifting plate 4 begins to descend, the cover plate 3 does not move, and when the lifting plate 4 descends to the top limit position of the first push rod 10, along with the lifting plate 4 Continue to descend, the first push rod 10 is forced to slide down, and the cover plate 3 gradually falls until the cover plate 3 falls completely horizontally.

The spring 7 is a compressed air spring.

The shape of the first push rod 10 is S-shaped and arranged horizontally. The two ends of the S-shape are respectively slidably connected in two slideways, and the spring 7 controls the rise of the first push rod 10 and the structures on it.

When the display is driven up and down by the motor, the mechanical transmission mode and the spring 7 are used to control the turning and closing of the cover plate 3. The closing time of the cover plate 3 is inconsistent with the rising and falling time of the lifting platform. When rising, the cover plate 3 must be turned 90 degrees synchronously. When falling, the cover plate 3 must be closed at the end. Therefore, the first push rod 10 is designed to pull the L-shaped corner plate 12. Drive the cover plate 3 to cover and lift.

This application adopts the electric lifting type, which improves the use feeling of the computer desk, and at the same time avoids the easy damage of the display and the winding problems of the wires caused by the flipping type of the display screen on the market.

This application utilizes the positive and negative rotation of two synchronous stepping motors to drive the rise and fall of the lifting plate 4. The positive and negative rotation of the motor uses the ARDUINO main board control platform to generate and control the pulse signal. In order to facilitate management, RFID technology can be used For identity verification management (that is, credit card authentication), only after authorization can the control of the computer lifting platform be turned on, which makes the computer more secure.

The first push rod 10 is S-shaped, its upper end is rotatably connected with the second push rod 11 and is slid up and down in the first slideway 8 , and its lower end is slid up and down in the second slideway 9 . Such design makes the cover plate 3 always rise before the display when the lifting plate 4 rises, and the cover plate 3 falls behind the display when the lifting plate 4 descends.

When the cover plate 3 is horizontal, the angle formed by the two positioning plates of the L-shaped corner plate 12 is located in the third quadrant. Such a design enables the first push rod 10 to achieve the maximum turning effect of the cover plate 3 with the minimum stroke.

The first slideway 8 is opposite to the second slideway 9 . Such a design ensures the overall sliding stability of the lifting assembly of the cover plate 3 .

Offer some through holes 4-1 on the lifting plate 4, and the main chassis is positioned at the bottom of the hidden box 2 below the lifting plate 4, and the connecting wires between the display and the main chassis are correspondingly worn in some through holes 4-1. With such a design, the connecting wires are all arranged in the hidden box 2, and the desktop is guaranteed to be clean and tidy when the computer is hidden and set.

The bottom of the first push rod 10 is fixedly connected with the spring 7 .
