Description

Technical Field

[0001] The utility model belongs to the technical field of teaching equipment, and specifically relates to an adjustable whiteboard. Background Art

[0002] An electronic whiteboard, also known as an electronic interactive whiteboard, is a multifunctional high-tech teaching and display tool that integrates the functions of a blackboard, a computer, a projector, etc. It can achieve human-computer interaction through touch or other input devices and is widely used in multiple scenarios such as education, training, and meetings. The electronic whiteboard can not only replace the traditional writing whiteboard but also display multimedia content through the integrated computer system, improving the efficiency of information transmission and greatly enhancing the interactivity of teaching and meetings.

[0003] However, traditional electronic whiteboards usually adopt fixed support frames, resulting in inconvenient angle adjustment during use. Since the whiteboard is usually in a fixed vertical position, users are prone to discomfort during operation, especially during long-term writing or display. At the same time, the traditional support frame design cannot achieve precise angle adjustment and locking, so there is still a risk of angle deviation after the whiteboard is adjusted to the ideal angle, affecting the user experience. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable whiteboard to solve at least one of the problems and defects mentioned in the above background art.

[0005] An adjustable whiteboard is provided, including a support frame body. Installation frames are arranged on both sides of the support frame body. Electric push rods are arranged on both of the two installation frames. The telescopic ends of the two electric push rods are respectively fixedly connected with a first installation pedestal and a second installation pedestal. The first installation pedestal and the second installation pedestal are both slidably connected in the installation frames. A whiteboard main body is rotatably connected between the two installation frames. A driving mechanism is arranged on the first installation pedestal, and the output end of the driving mechanism is fixedly connected to one side of the whiteboard main body. An angle adjustment mechanism is arranged on the second installation pedestal, and the angle adjustment mechanism is fixedly connected to the side of the whiteboard main body far from the output end of the driving mechanism.

[0006] Furthermore, a set of sliding grooves are respectively arranged inside the two installation frames. The first installation pedestal and the second installation pedestal are respectively slidably connected to the two sets of sliding grooves. The sliding grooves limit the movement ranges of the first installation pedestal and the second installation pedestal, enabling them to slide only along the preset trajectories, thereby ensuring the stability of the overall structure. Under the action of the electric push rods, they move up and down in the installation frames to realize the adjustment of the overall height of the whiteboard main body.

[0007] Further, the driving mechanism includes a driving motor, which is arranged on one side of the upper part of the first mounting pedestal. The output end of the driving motor is fixedly connected with a transmission gear, which is meshed with a transmission gear ring. The transmission gear ring is fixedly connected with a first rotating shaft, which is fixedly connected to the whiteboard main body. The first rotating shaft is rotatably connected to the first mounting pedestal. When the driving motor is started, the transmission gear rotates to drive the transmission gear ring to rotate synchronously. The rotation of the transmission gear ring is transmitted to the whiteboard main body through the first rotating shaft, so that the whiteboard main body rotates. Through the drive of the driving motor and gear transmission, the user can precisely control the rotation angle of the whiteboard to meet the requirements of different usage scenarios.

[0008] Further, the angle adjustment mechanism includes a second rotating shaft, a locking rod and an angle adjustment disc. The second rotating shaft is fixedly connected to one side of the whiteboard main body and is rotatably connected to the second mounting pedestal. The second rotating shaft is fixedly connected with a locking rod. The second mounting pedestal is provided with an angle adjustment disc, on which several angle scale lines are arranged. During the process of the driving mechanism driving the whiteboard main body to rotate, the second rotating shaft is synchronously driven to rotate. When the whiteboard main body is adjusted to a proper angle, the locking rod can be mechanically fixed at a specific position to prevent the whiteboard main body from further rotating and ensure that the whiteboard main body remains at the set angle.

[0009] Further, several threaded holes are arranged on the angle adjustment disc, and the several threaded holes are arranged in one-to-one correspondence with the angle scale lines. The multiple threaded holes correspond to different angle scale lines, enabling the user to select multiple fixed angles according to needs. This design allows for flexible adjustment of the whiteboard to multiple common angles while ensuring reliable fixation at each angle.

[0010] Further, the locking rod is also provided with a through hole, and a locking bolt for passing through the through hole and the threaded hole is arranged on the locking rod. Each threaded hole corresponds to a specific angle line. The user can insert the bolt at the corresponding position to lock the whiteboard main body at the corresponding angle. The threaded hole provides a stable fixing point to ensure that the whiteboard main body does not rotate after being adjusted to the ideal angle. When the whiteboard main body rotates to a specific angle, the locking rod can be fixed in position by screwing into the corresponding threaded hole.

[0011] Further, a storage bin is also arranged on one side of the upper part of the whiteboard main body, which can be used to store relevant tools and accessories for using the whiteboard, such as pens, wipes, remote controls, charging cables, etc., to ensure that these items are readily available and increase the operation convenience.

[0012] Further, several universal wheels are arranged below the support frame body, which facilitates the handling and movement of the entire support frame body.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The telescopic action of the electric push rod can drive the mounting pedestal to slide up and down in the mounting frame, thereby realizing the height adjustment of the whiteboard main body. Compared with the traditional manual adjustment method, the electric push rod makes the height adjustment more convenient and accurate, and can realize remote control or preset height through the electric control system. The driving mechanism is driven by a motor to enable the whiteboard main body to perform rotational adjustment within a set range. Through motor control, users can easily adjust the angle of the whiteboard. The angle adjustment mechanism can cooperate with the driving mechanism to provide precise fine adjustment of the angle of the whiteboard main body. At the same time, the angle adjustment mechanism locks the rotated angle of the adjusted whiteboard main body to ensure that the whiteboard main body does not shift after being adjusted to the target angle. The whiteboard angle adjustment is convenient, and the whiteboard does not shift when adjusted to the ideal angle, improving the convenience and accuracy of use. BRIEF DESCRIPTION OF THE DRAWINGS
