TECHNICAL FIELD

[0001] The application relates to the technical field of photoelectric combined slip rings, in particular to a micro photoelectric combined slip ring structure. BACKGROUND

[0002] The photoelectric combined slip ring belongs to a rotary connector, is usually installed at the rotating center of equipment, and has the function of integrating an optical fiber slip ring and an electric slip ring together through a clever and compact structure design, so that the transmission of optical signals and electric signals can be realized between two parts that are continuously rotated by 360 degrees, the transmission of power can be realized through the electric slip ring, and the transmission of high-frequency signals can be realized through the optical fiber slip ring. The photoelectric combined slip ring combines the advantages of the electric slip ring and the optical fiber slip ring together, the weak and easily interfered detection signals are transmitted by the optical fiber, and the strong current signals with relatively large power are transmitted by the electric slip ring, so that the possibility that the weak signals are interfered by external electromagnetic interference is completely avoided. Thus, the possibility that the slip ring signals are interfered by electromagnetic interference is greatly reduced as a whole, and the function of simultaneously transmitting multiple signals in a relatively small volume is realized. As can be known from the fact that the photoelectric combined slip ring structure integrates the optical fiber slip ring and the electric slip ring together, the sizes of the optical fiber slip ring and the electric slip ring in the radial direction are accumulated, so that the volume cannot be made smaller. Therefore, the inventor provides a micro photoelectric combined slip ring structure. SUMMARY

[0010] Further, a third cavity is formed in the stator part of the electric slip ring, and the stator-end fiber collimator is installed in the third cavity.

[0011] Further, the third cavity is in communication with the first cavity, and the diameter of the third cavity is smaller than the diameter of the first cavity.

[0012] Further, the diameter of the third cavity is the same as the diameter of the second cavity.

[0013] Further, the rotor-end fiber collimator is installed at one end of the second cavity close to the third cavity, and the stator-end fiber collimator is installed at one end of the third cavity close to the second cavity.

[0023] This application addresses the limitation of existing optoelectronic combined slip rings in terms of size reduction by providing a miniaturized optoelectronic combined slip ring structure. Specifically, while retaining the transmission function of the original optoelectronic combined slip ring integrated with a single-channel fiber optic slip ring and an electrical slip ring, the overall size of the optoelectronic combined slip ring is reduced by optimizing the layout and integration of the electrical and fiber optic slip rings, increasing its applicability in limited spaces, and thus achieving a lightweight design for the entire equipment system.

[0024] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0025] This application provides a miniature optoelectronic combined slip ring structure, such as... Figure 1 As shown, it includes an electric slip ring and an optical fiber collimator; the electric slip ring includes an electric slip ring rotor part 1 and an electric slip ring stator part 4; the optical fiber collimator includes a rotor-end optical fiber collimator 2 and a stator-end optical fiber collimator 3; the rotor-end optical fiber collimator 2 is installed in the electric slip ring rotor part 1, and the stator-end optical fiber collimator 3 is installed in the electric slip ring stator part 4.

[0026] Specifically, the miniature optoelectronic combined slip ring structure provided in this application includes an electric slip ring and an optical fiber collimator. The principle of the miniature optoelectronic combined slip ring structure is to remove the metal shell, bearings, and other structures used to fix the collimator for transmitting optical signals in the original optical fiber slip ring structure, replacing them with the internal structure of the electric slip ring. This reduces the volume of the optical fiber slip ring and the optoelectronic combined slip ring, with the radial dimension reduced by approximately 10mm. Ultimately, this achieves simultaneous 360° continuous rotation of the electric slip ring and transmission of electrical signals, while the optical fiber collimator simultaneously achieves 360° continuous rotation and transmission of optical signals. The miniature optoelectronic combined slip ring structure is an integrated layout of the electric slip ring and the optical fiber slip ring, reducing the overall size of the optoelectronic combined slip ring, increasing its applicability in limited spaces, and thus achieving lightweighting of the entire equipment system.

[0027] The miniature optoelectronic combined slip ring structure provided in this application retains the transmission function of the original optoelectronic combined slip ring integrated with the single-channel fiber optic slip ring and the electric slip ring. By optimizing the layout and integration of the electric slip ring and the fiber optic slip ring, the overall size of the optoelectronic combined slip ring is reduced, increasing its applicability in limited spaces, thereby achieving the lightweighting of the entire equipment system.

[0028] In some embodiments, the stator portion of the electric slip ring has a first cavity inside, and the rotor portion of the electric slip ring is disposed within the first cavity.

[0029] In some embodiments, the electric slip ring rotor portion is coaxially arranged with the electric slip ring stator portion.

[0030] In some embodiments, the rotor-end optical fiber collimator is fixedly connected with the electric slip ring rotor portion.

[0031] In some embodiments, the stator-end optical fiber collimator is fixedly connected with the electric slip ring stator portion.

[0032] In some embodiments, a second cavity is formed in the electric slip ring rotor portion, and the rotor-end optical fiber collimator is installed in the second cavity.

[0033] In some embodiments, a third cavity is further formed in the electric slip ring stator portion, and the stator-end optical fiber collimator is installed in the third cavity.

[0034] In some embodiments, the third cavity is in communication with the first cavity, and the diameter of the third cavity is smaller than the diameter of the first cavity.

[0035] In some embodiments, the diameter of the third cavity is the same as the diameter of the second cavity.

[0036] In some embodiments, the rotor-end optical fiber collimator is installed at one end of the second cavity close to the third cavity, and the stator-end optical fiber collimator is installed at one end of the third cavity close to the second cavity.

[0037] In the manufacturing process, the internal structure of the electric slip ring is used to replace the metal shell, bearing and other structures in the original optical fiber slip ring structure for fixing the collimator for transmitting optical signals. The internal structure of the electric slip ring is used to fix the stator-end and rotor-end optical fiber collimators, so that the electric slip ring can rotate continuously for 360 degrees and transmit electrical signals, and the optical fiber collimator can also rotate continuously for 360 degrees and transmit optical signals. Based on the transmission function of the original integrated optical-electric combined slip ring, the layout and integration of the electric slip ring and the optical fiber slip ring are optimized to reduce the overall size of the optical-electric combined slip ring, increase its applicability in limited space, and further realize the lightweight of the entire equipment system.

[0038] Compared with the conventional optical-electric combined slip ring structure, the micro optical-electric combined slip ring structure provided in the embodiments has reasonable design of each part, compact and simple mechanism, reduced overall size of the optical-electric combined slip ring, increased applicability in limited space, and further realized lightweight of the entire equipment system.
