Problems solved by technology
At present, traditional rotary connectors have obvious shortcomings: ①Large volume and high weight
Due to the influence of the internal structure of the rotary connector, it has a large volume and high weight, which limits many usage scenarios; ②Low data transmission rate
When the brush wire and slip ring rotate at high speed, the contact point impedance discontinuity will lead to data loss; ③Low life
The contact friction between the brush wire and the slip ring will cause contact sparks and affect the transmission reliability; ⑤ cannot rotate at high speed for transmission
Data transmission is performed during high-speed rotation, the contact impedance is discontinuous, the transmission of high-speed signals is discontinuous, and even high-speed signals cannot be transmitted

The invention relates to a wireless data transmission rotary connector which comprises a rotor part and a stator part, the rotor part comprises a rotor end interface connector, a flange plate, a rotating shaft and a rotor end printed board part, and the stator part comprises a stator end interface connector, a tail end cover, an outer shell and a stator end printed board part. The rotor-end interface connector is fixed on the flange which is fixed at one end of the rotating shaft, and the rotor-end printed board component is installed at the other end of the rotating shaft. The stator end interface connector is fixed to the tail end cover, and the outer shell is rotationally connected with the rotating shaft through a bearing so that the rotor component can rotate relative to the stator component. The rotor end printed board component is provided with a first wireless chip, and the stator end printed board component is provided with a second wireless chip which carries out bidirectional wireless data transmission with the first wireless chip. The wireless transmission technology is adopted to replace a traditional contact type data transmission mode, and it is guaranteed that the product is small in size and light in weight, and meanwhile high-speed transmission data is stable and free of loss.
Description
technical field [0001] The invention belongs to the technical field of rotary connectors, in particular to a wireless data transmission rotary connector. Background technique [0002] With the advent of the 5G era, the existing rotary connectors can no longer keep up with the growing demand. As modern industrial scenarios demand faster and more reliable data transmission between rotating parts, the requirements for bandwidth, crosstalk, and EMI performance of data interfaces used in rotary joints are increasingly stringent. Meeting these requirements is crucial to guarantee real-time operation, continuous uptime and maximum efficiency of the corresponding industrial equipment. In the military, as the equipment is updated, the rotation speed of the rotary connector is required to be higher and higher, the life is longer, and the transmission rate is gradually increased to Gbps. At present, traditional rotary connectors have obvious shortcomings: ①Large volume and high weigh...
