Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support equipment technology, specifically a universal connector for photovoltaic supports. Background Technology

[0002] After the photovoltaic (PV) bracket has undergone angle adjustment, if another angle adjustment function is added to the upper side of the bracket for mounting the PV bracket, then a universal joint connector will be used. The drawback of existing universal joint connectors is that the existing universal joint structure cannot transmit power from the bottom motor to the swinging bracket, resulting in the PV bracket and base connected by the universal joint not being able to smoothly perform individual or simultaneous angle adjustments. Extensive research has been conducted on this issue. Utility Model Content

The feature is that a driving component for driving the base to rotate is disposed on one side of the mounting base, a second motor is disposed inside the mounting base, and a universal joint assembly is disposed on one side of the second motor and connected and fixed to the inner rotating shaft.

[0005] A further technical solution includes a driven bevel gear disposed on one side of the base, a first motor disposed on one side of the driven bevel gear, and a driving bevel gear being poweredly connected to one side of the first motor. The driving bevel gear meshes with the driven bevel gear, and the first motor is disposed on one side of the mounting base.

[0006] In a further technical solution, a bracket is provided on one side of the mounting base, and the bracket is fixedly connected to the first motor.
