Description

Multidirectional corner supporting seat

Technical Field

The utility model relates to the technical field of mechanical equipment, in particular to a multidirectional corner support seat.

Background

The supporting seat for controlling the rotation angle of the longitudinal direction 360 degrees of the related equipment and controlling the rotation angle of the transverse direction 360 degrees of the related equipment is a device used in multiple industries. For example, in order to achieve a good monitoring effect, a main control module (including a single-chip microcomputer module, a PLC (programmable logic controller) or a small computer system) of the monitoring device is controlled by an internal circuit, and the monitoring visual angle range of one or more cameras is adjusted within a certain angle in the longitudinal direction and the transverse direction in a motor speed reducing mechanism mode, so that a better monitoring effect is achieved (or 3D modeling scene manufacturing in VR application is achieved, and the main control module is used for controlling the multiple cameras to acquire field image data and the like under different angles through the internal circuit, so that a good image acquisition effect is achieved); for example, in order to facilitate the people at the front end of the display screen to watch the displayed content, the main control module needs to adjust the display range of the display screen in a certain angle in the longitudinal direction and the transverse direction by a motor speed reducing mechanism mode through an internal circuit. At present, the mode of controlling a motor speed reducing mechanism by a main control module of related equipment is based on an internally set mode, is influenced by factors such as power supply voltage change and the like (for example, voltage is too low, a voltage stabilizing device matched with the equipment cannot output a power supply with stable voltage to the main control module), and when the main control module outputs a control signal to a power supply input end of the motor speed reducing mechanism, the motor speed reducing mechanism drives related equipment to move in place (for example, the main control module controls a corresponding set of motor speed reducing mechanism to drive the related equipment to work for 5 seconds, and because the power supply time output by the main control module is fixed, when the input voltage is normal, the related equipment can be effectively driven in place, but when the input voltage is too high or too low, the related equipment may not be in place.

In the prior art, a supporting seat for controlling the rotation angle of the related equipment in the longitudinal direction and the transverse direction 360 is generally structured, and the supporting seat comprises a lower supporting table and an upper supporting table, wherein the lower supporting table and the upper supporting table are rotationally connected through bearings, equipment to be controlled is rotationally connected with the upper supporting table through a shaft rod and bearings, when one set of matched motor reducing mechanism drives the lower supporting table to transversely rotate, the upper supporting table and the equipment transversely rotate back and forth, and when the other set of matched motor reducing mechanism drives the equipment to rotate, the equipment longitudinally rotates left and right. The applicant searches the related technology in the field such as national institute website, related patent website and other input keywords such as universal supporting seat, and the like, and is similar to the technology of the application, such as patent number 201510453531.0 in China and patent name universal supporting seat. The above-mentioned device can not cooperate with motor reducing mechanism, etc., but can only be operated in manual mode, so that it can not be used in automatic control place; in practical application, the rotation angle of other equipment in the transverse direction or the longitudinal direction is limited (after the connecting rod between the supporting seat and the supporting body is contacted with the upper end of the connecting sleeve, the rotation angle of the equipment in the front, back, left and right directions is limited), and the defects are more obvious when the device is particularly applied to multi-camera angle conversion image acquisition and multi-angle video display equipment; finally, the comparison patent cannot output an angle turning signal to the main control module of the related equipment, so that the main control module cannot obtain angle adjustment feedback and cannot realize intelligent control. In summary, the supporting seat is mainly used for equipment for acquiring images by converting angles of multiple cameras and displaying multi-angle videos, not only can conveniently adjust various angles in the transverse direction and the longitudinal direction, but also can output adjusting signals to a main control module of related equipment in real time.
