Description

Technical Field

[0001] The utility model relates to the technical field of ergonomic chairs, in particular to an arm support mechanism of an ergonomic chair. Background Art

[0002] Among the ergonomic chairs currently in use, the support arms of most ergonomic chairs can be adjusted up and down, but during the adjustment process, the user needs to constantly pull up. When too much force is used, the support arm will be pulled to a higher position, which is not suitable for the user to use. Therefore, the user needs to press down to make the support arm retract downward. During this adjustment process, time will be wasted, which may affect the work of the user. Utility Model Content

[0003] The purpose of the utility model is to provide an arm support mechanism for an ergonomic chair, so as to solve the problem that in the process of adjustment, time will be wasted, which may affect the work of the user.

[0005] Preferably, a connecting plate is provided under the support plate, a storage groove is opened on the top surface of the connecting plate, a servo motor is fixed inside the storage groove, the servo motor is electrically connected to the single-chip computer, a rotating column is fixed to the output shaft of the servo motor, a rotating sleeve is fixed on the bottom surface of the support plate, and the rotating column is fixed inside the rotating sleeve.

[0006] Preferably, a limiting groove is provided on the top surface of the connecting disk, a limiting block is fixed on the bottom surface of the supporting plate, and the limiting block is slidably arranged with the limiting groove.

[0007] Preferably, a protective pad is fixed to the top surface of the support plate.

[0008] Preferably, a mounting ring is slidably provided on the outer wall of the support tube, a threaded hole is opened on the outer wall of the mounting ring, the mounting ring and the support tube are threadedly connected through bolts and the threaded hole, a mounting frame is fixed to the outer wall of the mounting ring, and the mounting frame is composed of a rectangular plate and a cylinder.

[0009] Preferably, the thickness of the support plate is 3 cm.

[0010] Compared with the prior art, the arm support mechanism of an ergonomic chair adopting the above technical solution has the following beneficial effects:

[0011] 1. During use, the user sits on the engineering chair and places the arm on the pallet. The pressure of the arm is sensed by the pressure sensor, and the data is transmitted to the single-chip microcomputer. The single-chip microcomputer controls the hydraulic rod to open, and the telescopic end of the hydraulic rod is extended and retracted upward, pushing the pallet upward. At the same time, the user's chest is scanned by an infrared scanner to determine the height of the user when sitting, so as to determine the height of the pallet when it rises automatically. When the pallet reaches a certain height, it stops rising. Then, the user can automatically adjust the height through the touch screen according to personal habits or comfort to achieve the optimal height. The use of this mechanism can quickly and automatically adjust the height of the engineering chair, thereby saving the user's time and physical strength, and improving the user's comfort;

[0012] Second, during use, the output shaft of the servo motor rotates to drive the rotating column to rotate, so that the rotating sleeve can rotate, so that the support plate can rotate, which is conducive to the left and right adjustment of the support plate, thereby meeting the needs of users and improving practicality. The sliding setting of the limit block and the limit groove can make the support plate more stable when rotating, thereby reducing the shaking of the user's arm on the support plate;

[0013] 3. During use, the softness of the protective pad can make the user's arms more comfortable when placed, thereby reducing the user's fatigue caused by long-term placement, and also increase the friction between the arm and the support plate to prevent the arm from slipping when placed. The entire arm support mechanism can be stably installed on the ergonomic chair through the mounting ring and the mounting frame, thereby providing convenience for the user.
