Description

Technical Field

[0001] The invention relates to the electrical field, in particular to a rotary current collector and a rotary dining table thereof. Background Art

[0002] In the field of mechanics, the power supply structure between two rotating parts is a problem that technicians in this field need to overcome. Chinese patent document CN216903375U discloses a rotating power supply, including a fixed disk and a rotating disk. One end of the rotating disk is provided with a rotating shaft that rotates with the fixed disk. Two mutually isolated first and second power supply coils are sleeved on the rotating shaft. A bus is provided on the fixed disk. Two first and second conductive springs are provided on the fixed disk, which elastically abut the first and second power supply coils, respectively. The input end of the bus is connected to the first conductive spring, and the output end of the bus is connected to the second conductive spring. At least one set of branch lines is provided on the rotating disk. The input end of the branch line is connected to the first power supply coil, and the output end of the branch line is connected to the second power supply coil. This patented structure achieves the purpose of energizing by elastically abutting the outer side of the corresponding energizing coil through the elastic force of the conductive spring itself. However, with the extension of usage, the elastic force of the conductive spring itself will weaken, resulting in a decrease in abutment stability, which in turn directly affects the reliability of energization. In addition, in order to reduce the frictional resistance between the conductive spring and the energizing coil, the contact area between the conductive spring and the energizing coil is small, so the amount of energization is small, which in turn restricts the power consumption of the power terminal and can only be adapted to low-power power terminals. In addition, this energizing structure is often suitable for unidirectional rotation in a set direction. Rotation in the opposite direction of the set direction can easily cause the conductive spring to be deformed by force, which directly affects the energizing effect.

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] See also Figures 1-11 The rotary current collector E involved in this embodiment includes a first rotating part 1, a second rotating part 15, and a rotating power connection assembly; the rotating power connection assembly includes a power receiving part electrically connected to the power supply terminal A, a power transmission part electrically connected to the power terminal B, and a conductive rolling part; the first rotating part 1 and the second rotating part 15 are coaxially rotatably connected to each other, and the rotating shaft is c; the power receiving part is fixedly arranged on the first rotating part 1 and rotates with the first rotating part 1; the power transmission part is fixedly arranged on the second rotating part 15 and rotates with the second rotating part 15; the power receiving part and the power transmission part are distributed correspondingly up and down, and under the action of gravity, the conductive rolling part is clamped between the power receiving part and the power transmission part to assist the first rotating part 1 to rotate relative to the second rotating part 15; the power receiving part is electrically connected to the power transmission part through the conductive rolling part. In this rotary current collector E, the conductive rolling component is clamped between the power receiving component and the power transmission component under the action of gravity, realizing electrical connection between them. The power-carrying performance will not be affected by long-term use, thereby ensuring the power-carrying reliability and stability; in addition, the conductive rolling component can ensure that the first rotating component 1 and the second rotating component 15 rotate smoothly with each other, and the conductive rolling component has a large contact area with the power receiving component and the power transmission component, respectively, which effectively increases the power carrying amount and is suitable for high-power power terminals; in addition, the rotation direction between the first rotating component 1 and the second rotating component 15 will not affect its power-carrying performance, that is, this power-carrying structure is not restricted by the rotation direction, is simple and convenient to use, and has a good user experience.

[0032] Furthermore, the conductive rolling component includes a rolling bracket 18 coaxially engaged with the rotating shaft c, and a plurality of conductive rollers 19 rollingly mounted on the rolling bracket 18. These rollers 19 roll between the power receiving component and the power transmission component, electrically connecting the power receiving component and the power transmission component. Specifically, the presence of a plurality of conductive rollers 19 effectively increases the power connection area, thereby increasing the overall power flow, making it suitable for high-power terminals.

[0033] Furthermore, a plurality of conductive rollers 19 are annularly distributed on the rolling support 18 and are each cylindrical, with the rolling axes d of the conductive rollers 19 extending radially relative to the rolling support 18. Specifically, to ensure rolling balance of the conductive rolling component, the conductive rollers 19 are evenly distributed in an annular pattern, and the diameter of the conductive rollers 19 is greater than the thickness of the rolling support 18, so that the conductive rollers 19 at least partially protrude from the top and bottom of the rolling support 18, ensuring electrical connection between the conductive rollers 19 and the power receiving and power transmitting components, respectively. The use of these rollable conductive rollers 19 significantly improves the load-bearing capacity of the rotary current collector E, enhancing its durability.

[0034] Furthermore, the rotating power connection assembly also includes a conductive gasket and a conductive spring. In this embodiment, the conductive gasket and the conductive spring are respectively disposed between the conductive rolling component and the power receiving component. The conductive rolling component rolls on the conductive gasket, and the conductive spring acts on the conductive gasket to press the conductive rolling component, which in turn presses the conductive spring on the power receiving component. The conductive rolling component is electrically connected to the power receiving component via the conductive gasket and the conductive spring. (When corresponding conductive gaskets and conductive springs are disposed between the conductive rolling component and the power transmission component, the conductive rolling component rolls on the conductive gasket, and the conductive spring acts on the conductive gasket to press the conductive rolling component, which in turn presses the conductive spring on the power transmission component. The conductive rolling component is electrically connected to the power transmission component via the conductive gasket and the conductive spring.) Specifically, the conductive spring elastically acts on the conductive rolling component and the power receiving component (or the power transmission component), respectively, effectively preventing errors in production and processing from causing a gap between the conductive rolling component and the power receiving component, thereby affecting power connection. In other words, the conductive spring can effectively compensate for this gap, ensuring proper power connection between the two.
