Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pivot, especially a pivot and screen device of multi-angle rotation. BACKGROUND

[0002] With the continuous evolution of technology, various mechanical equipment and electronic equipment are increasingly widely used in people's daily life and industrial production. Among them, the pivot as a key mechanical component exists in large quantities in many devices, mainly used to realize the physical connection and motion transmission function between different components.

[0003] However, in actual application scenarios, when the pivot is used to achieve physical connection, the problem of electrical connection cannot be ignored. In many devices, electrical connection operations such as power transmission or signal transmission between different components are essential to ensure the normal operation of the device. For example, in some devices where sensors and data processing units are connected, the sensor needs to transmit the signals collected by it to the data processing unit for analysis and processing through electrical connection; in the electric actuator, the control signal is transmitted to the motor driver through electrical connection, so as to control the running state of the motor.

[0004] The traditional pivot structure focuses on the mechanical structure building and the improvement of physical connection function in design and function implementation, and the consideration of electrical connection wiring channel is relatively less. In the conventional design, the electrical connection wiring is often completed by setting wiring holes, grooves and other ways on the device shell, or by connecting the wires to the corresponding components through external wiring mode. Although these ways can solve the problem of electrical connection to some extent, they also have many disadvantages.

[0005] On the one hand, setting wiring holes, grooves and other operations on the device shell will damage the overall integrity and sealing of the device shell, making it easy for dust, moisture and other external substances to enter the device, which will have adverse effects on the reliability and service life of the device. Especially in outdoor devices, food processing equipment and other application scenarios with high environmental requirements, such damage to the sealing may cause serious safety hazards and quality problems.

[0006] On the other hand, the external wiring mode not only makes the device appearance messy and affects the overall aesthetics of the product, but also easily causes wire entanglement, pulling and other situations in the wiring process, which brings many inconveniences to the installation, maintenance and use of the device. In addition, the external wiring is exposed to the external environment, which is easy to be affected by electromagnetic interference and mechanical damage, thus greatly reducing the stability and reliability of electrical connection.
