Abstract
Description
Technical Field
[0001] This application relates to the technical field of security equipment, specifically to a new direct drive structure for the ball machine motor. Background Technique
[0002] A surveillance ball machine, also known as an intelligent spherical camera or a spherical camera, is a commonly used device in modern video surveillance systems.
[0003] Currently, the power component inside the surveillance ball machine uses a method of motor plus gear drive to drive the rotation of the ball machine. However, with the increase of the usage time in the motor plus gear drive method, the gears in the gear drive system will gradually wear during long-term operation, resulting in an increase in the gear clearance, thus affecting the rotation accuracy and stability. Moreover, the gear clearance in the gear drive system may cause backlash, affecting the repeat positioning accuracy of the system, resulting in the rotation accuracy of the surveillance ball machine being affected after a period of use. Content of the Utility Model
[0004] The purpose of this application is to provide a new direct drive structure for the ball machine motor to solve the technical problems raised in the above background technique.
[0005] To achieve the above purpose, this application provides the following technical solution: A new direct drive structure for the ball machine motor, including a wall-fixed bracket and a rotating bracket rotatably connected to one side of the wall-fixed bracket. A stepper motor is fixedly connected inside the wall-fixed bracket, and the output shaft of the stepper motor is fixedly connected to the rotating bracket.
[0006] In one implementation, a bearing is connected inside the wall-fixed bracket. An extension end inserted into the inner ring of the bearing is integrally formed at the top of the rotating bracket, and the outer surface of the extension end is fixedly connected to the inner wall of the inner ring of the bearing. The output shaft of the stepper motor is fixedly connected to the upper end of the extension end.
[0007] In one implementation, two antennas are symmetrically connected to one side of the wall-fixed bracket.
[0008] In one implementation, a supplementary light is also fixedly connected to the outer surface of one side of the wall-fixed bracket.
[0009] In one implementation, a camera is installed inside the rotating bracket.
[0010] Compared with the prior art, the beneficial effects of this application are:
[0011] By changing the traditional gear drive structure to a direct drive by a stepper motor, this application avoids the energy loss of components such as gears and belts in the traditional drive system, thereby improving the energy conversion efficiency. It also uses smaller-sized bearings to ensure the stability of the product while guaranteeing the rotation accuracy, improving the utilization rate of the motor power, reducing the accessories of the product, and greatly reducing the procurement and assembly costs of the product.
