Description

Technical Field

[0001] This utility model relates to the field of display flipping technology, and more specifically to a display flipping device. Background Technology

[0002] Display control mechanisms, which control the angle of displays or LCD screens and facilitate human-computer interaction, are widely used in various fields. Various large displays or LCD screens need to be rotated as required, firstly for storage purposes (e.g., placing them on a wall or ceiling when not in use), and secondly for more comfortable viewing or to reduce work fatigue.

[0003] In existing technologies, the control mechanisms of various displays are complex in structure, large in size, occupy a lot of space, and are time-consuming, labor-intensive, and costly to install, disassemble, and maintain. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a compact, low-cost, and easy-to-install, disassemble, and maintain display flipping device.

[0005] A display flipping device includes a display fixing plate, on which a display is fixed. The display fixing plate is connected to a flip cover, which is rotatably connected to a mounting box. A motor is fixed inside the mounting box, and a sliding mechanism is provided on the motor. A rotating mechanism is provided between the flip cover and the mounting box. The motor drives the sliding mechanism to move left and right, and the sliding mechanism drives the rotating mechanism to rotate, so as to realize the rotation of the display on the display fixing plate from 0 to 90 degrees.

[0006] This utility model features a compact and reasonable structure, making it easy to install, disassemble, and maintain. The drive motor uses pulse current to control the number of revolutions of the lead screw; the pulse signal provides high precision in controlling the current, thus ensuring accurate rotation angles.

[0007] As a further improvement and supplement to the above solution, this utility model also includes the following additional technical features: The sliding mechanism includes a lead screw mounted on a motor, two sliding blocks mounted on the lead screw, and guide rods on both sides of the two sliding blocks. Rotation of the lead screw causes the sliding blocks to move left and right. The structure is compact and reasonable, and the sliding is stable and reliable. The guide rods effectively guide the movement, ensuring linear motion.

[0008] The mounting box includes an upper fixing plate, a lower fixing plate, front and rear fixing plates, and left and right fixing plates. The lower fixing plate has an opening in the middle. The left and right fixing plates have elongated slots in the shape of waists. The structure is compact and reasonable, occupies little space, and is convenient for installation, disassembly, and maintenance.

[0009] The rotating mechanism consists of rocker arms on both sides, connected at an angle. One end of the rocker arm passes through a waist-shaped slot and connects to a sliding block, while the other end connects to the flip cover. The screen flips by sliding the sliding block. The flipping mechanism is reasonable and stable. The rocker arms and the sliding block form a triangular structure, which is the most stable structure, preventing wobbling during flipping and remaining stable even at a specified angle.

[0010] The motor is equipped with an electrical control system for controlling its rotation. This enables human-machine interaction and achieves a high degree of automation.

[0011] The monitor mounting plate has four fixed blocks. Fixing is convenient and quick, and the structure is stable.

[0012] The monitor mounting plate is equipped with bent lugs and has multiple square slots. It is lightweight and has good strength.

[0013] The left and right fixed plates are equipped with multiple heat dissipation holes. These holes dissipate the heat generated by the motor, ensuring normal operation.

[0014] The following advantages can be achieved by using this utility model: It has a compact, simple, and reasonable structure, occupies little space, and is structurally stable. Installation, disassembly, and maintenance are convenient. It is lightweight and has good strength. The sliding and flipping structure is reasonable and has good stability. It is low in cost and easy to control. The drive motor uses pulse current to control the number of revolutions of the lead screw; the pulse signal provides high precision for controlling the current, thus ensuring accurate flipping angles.

[0015] The rocker arm and the slider form a triangular structure, which is the most stable structure and will not cause wobbling when flipping. It remains stable even at a specified angle. Attached Figure Description

[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, this utility model is a display flipping device.

[0023] The display flipping device described in this embodiment includes a display fixing plate 1, on which a display is fixed. The display fixing plate 1 is connected to a flip cover 3, which is rotatably connected to a mounting box. A motor 7 is fixed inside the mounting box, and a sliding mechanism is provided on the motor 7. A rotating mechanism is provided between the flip cover 3 and the mounting box. The motor 7 drives the sliding mechanism to move left and right, and the sliding mechanism drives the rotating mechanism to rotate, thereby realizing the rotation of the display on the display fixing plate 1 from 0 to 90 degrees. The bottom of the flip cover 3 is provided with a fixing screw for rotation and flipping.

[0024] Furthermore, the sliding mechanism includes a lead screw 8 sleeved on the motor 7, two sliding blocks 9 sleeved on the lead screw 8, and guide rods 10 on both sides of the two sliding blocks 9. The rotation of the lead screw 8 drives the sliding blocks 9 to move left and right. At the same time, the motor 7 used for driving adopts pulse current to control the number of revolutions of the lead screw. The pulse signal has high precision for controlling the current (output high level UH≥4.7V, duty cycle 45%~55%, phase difference of CH1 and CH2 30-90°±10°), thus making the flipping angle precise.

[0025] Furthermore, the mounting box includes an upper fixing plate 11, a lower fixing plate 2, front and rear fixing plates 4, and left and right fixing plates 5. The lower fixing plate 2 has an opening in the middle. The left and right fixing plates 5 are provided with waist-shaped elongated grooves 51. The lower fixing plate 2 and the flip cover 3 are spaced apart. The left and right fixing plates 5 and the flip cover 3 are respectively provided with extension ends, and the two extension ends are fixedly connected by bolts and nuts. The motor 7 is fixed on one of the front and rear fixing plates 4, and the two ends of the guide rod 10 are respectively fixed on both sides of the front and rear fixing plates 4.

[0026] Furthermore, the rotating mechanism is a rocker arm 6 arranged on both sides and connected obliquely. One end of the rocker arm 6 passes through the waist-shaped slot 51 and connects to the sliding block 9, while the other end is connected to the flip cover 3. The display is flipped by the sliding of the sliding block 9. The rocker arm 6 is at 0 degrees at one end of the waist-shaped slot 51 and at 90 degrees at the other end. The rocker arm and the sliding block form a triangular structure, which is the most stable structure and will not cause shaking during flipping, remaining stable even at the specified angle.

[0027] Furthermore, the motor 7 is equipped with an electrical control system for controlling rotation. This electrical control system is existing technology and will not be elaborated upon here. The electrical control system also includes a control panel and / or a remote control, which controls the angle. In this embodiment, the electrical control system uses a computer board.

[0028] Furthermore, the display mounting plate 1 is provided with four fixed blocks 101. The four blocks 101 are used to fix the display, and the blocks 101 have a hollow structure.

[0029] Furthermore, the display mounting plate 1 is provided with bent ear plates 102, and the display mounting plate 1 has multiple square slots. The square slots can reduce weight. At the same time, the cross-section of the flip cover 3 is a frame structure with an opening on one side, and the two sides of the frame are fixedly connected to the ear plates 102.

[0030] Furthermore, the left and right fixed plates 5 are provided with multiple heat dissipation holes 52. The heat dissipation holes 52 can dissipate the heat generated by the motor 7.

[0031] When this monitor flipping device is in use, the lower fixing plate 2 in the flipping device is installed in the corresponding fixed position, the drive motor and the computer board are connected, the power is plugged in, and it is controlled by the remote control or control panel to flip the angle according to the user's required angle. The monitor fixing plate is installed on the movable flip cover. When the remote control sends a command to the computer board, the computer board sends current to the drive motor according to the pulse current. The drive motor drives the sliding block and the lead screw to slide back and forth. The sliding block slides in the direction specified by the guide rod. The sliding block drives the rocker arm, and the rocker arm drives the flip cover, thereby achieving the effect of flipping the monitor or LCD screen angle.

[0032] The main advantages of this embodiment are: 1. During the flipping process, the rocker arm and the sliding block form a triangular structure. A triangular structure is the most stable structure, preventing any wobbling during flipping and ensuring stability even at the designated angle. 2. The drive motor uses pulse current to control the number of rotations of the lead screw. The pulse signal provides high precision in controlling the current, thus ensuring accurate flipping angles.

[0033] The above are preferred embodiments of the present utility model and do not limit the scope of protection of the present utility model. Any modifications and improvements made by those skilled in the art based on the design concept of the present utility model should be considered within the scope of protection of the present utility model.
