Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a novel telescopic module for telescopic fluid connectors. Background Technology

[0002] In the field of new energy flight equipment, especially electric flying cars, the power supply for these devices is new energy batteries (such as lithium-ion batteries). To achieve lightweight design, these devices lack a built-in thermal management system. The vertical descent phase of an electric flying car is the most energy-intensive part of flight, requiring deceleration and precise maneuvers. This significant energy consumption heats the batteries, reaching temperatures of 60 degrees Celsius and above. However, the optimal operating temperature range for batteries is 10 to 45 degrees Celsius. Therefore, fluid connectors are needed to connect external liquid cooling sources and internal cooling channels to quickly cool the batteries to the optimal temperature range. Currently, fluid connectors are often of a direct-insertion structure, which presents a problem... Firstly, the direct-plug structure requires good alignment and pushing force, making it difficult to quickly align and install for rapid connection and disconnection. It also hinders rapid cooling, causing the battery to remain at excessively high temperatures for extended periods, potentially leading to dangerous overheating and degradation of the battery pack. Secondly, after landing, the electric flying car requires rapid charging for reuse. Poor thermal management during rapid charging causes the battery pack to operate at high temperatures, resulting in uneven and slow charging, which accelerates battery pack degradation and even poses safety risks. A considerable amount of time is needed to restore it to its optimal temperature range. Therefore, rapid charging and restarting of the electric flying car is not feasible, resulting in low equipment utilization. Utility Model Content

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0034] Figures 1 to 7 A novel telescopic module for a telescopic fluid connector according to one embodiment of the present invention is schematically shown. As shown, the novel telescopic module for a telescopic fluid connector includes: a fixed tube 1 in the middle of the bushing connection plug portion 01, a plurality of damping locks 2, and a rotating telescopic shaft 3 in the middle of the bushing connection socket portion 02;

[0035] The axial sliding hole 11 of the fixed tube 1 is provided with a plurality of radial connecting holes 10 in a circumferential array at the front end;

Preferably, the outer end of the radial connecting hole 10 is provided with a large-diameter limiting groove 12. The damping lock 2 includes a large-diameter cylindrical limiting cap 21 and a small-diameter damping pin 20. The damping pin 20 is integrally connected to the lower end of the limiting cap 21, and the limiting cap 21 is placed in the limiting groove 12. The damping pin 20 slides through the radial connecting hole 20 with the same diameter. This arrangement can ensure the high-precision and reliable vertical floating of the damping lock 2, and the overall size is small.

[0037] The rotary telescopic shaft 3 includes a cylindrical shaft 30. The rear end of the shaft 30 is integrally provided with a power input end 31 and the front end is provided with a sliding column 32 that is in diameter with the sliding hole 11. The outer wall of the sliding column 32 is provided with a plurality of spiral guide slides 33 arranged in a circular array. A guide arc surface 34 is formed on one side of the front port of the guide slide 33 and a stop groove 35 is provided on its rear end wall to position the end of the damping column 20. The sliding column 32 is inserted into the sliding hole 11. When the power input end 31 is rotated, the damping column 20 enters the guide slide 33 along the guide arc surface 34. The damping column 20 slides against the rear wall or front wall of the guide slide 33 to form a screw nut structure. The sliding column 32 extends into or retracts from the fixed tube 1, so that the socket part 02 and the plug part 01 are engaged or disengaged.

[0038] When the socket part 02 is inserted into the plug part 01, the sliding post 32 is inserted into the sliding hole 11. When the power input end 31 is rotated, the damping post 20 enters the guide slide 33 along the guide arc surface 34. When the power input end 31 is rotated again, the damping post 20 slides against the rear wall surface of the guide slide 33 to form a screw nut pair until the damping post 20 enters the stop groove 35. The sliding post 32 extends forward and fully into the fixed tube 1, so that the socket part 02 and the plug part 01 are fully inserted.

[0039] When the socket part 02 separates from the plug part 01, the power input end 31 is rotated in the opposite direction. After the damping column 20 disengages from the stop groove 35, the damping column 20 slides against the rear front wall of the guide slide 33 to form a screw nut structure until the damping column 20 disengages from the guide slide 33. The sliding column 32 then completely disengages from the fixed tube 1, and the socket part 02 and the plug part 01 are completely separated.

[0040] This novel telescopic module for telescopic fluid connectors employs a telescopic mechanism with a special screw-nut structure consisting of a guide slide 33 and a damping column 20. It achieves rapid and high-precision positioning via the guide arc surface 34, controls movement stability and accuracy via the guide slide 33, and positions and locks the end position via the stop groove 35. This enables rapid, stable, and high-precision linear telescopic movement, thus achieving a fast and reliable connector connection. Its advantages are: firstly, this structure allows for rapid and reliable connection and separation of the connector, enabling the battery pack to cool quickly and effectively to its optimal operating temperature range, avoiding overheating and degradation caused by prolonged exposure to excessively high temperatures, resulting in a longer service life; secondly, rapid cooling after the electric vehicle lands allows for… The electric flying car can quickly generate electricity for reuse, has good thermal management, and can be quickly charged at a suitable temperature without long waiting time, making it convenient to quickly charge and restart, resulting in high equipment utilization. Thirdly, the structure has a guide arc surface 34, which can achieve a good blind insertion effect and avoid the phenomenon of misalignment over a long period of time. Fourthly, a stop groove 35 is set. When installed in place, the damping column 20 will immediately fall into the stop groove 35. Under the action of no external force, the two ends will not separate, thus achieving a reliable locking connection. Fifthly, the sliding column 32 with equal diameter matching of sliding hole 11 and through the screw nut structure, has high motion accuracy and no left or right swing or displacement tilting phenomenon during movement, thus achieving stable linear insertion and removal, which is beneficial for quickly connecting liquid cooling.

The beneficial effect is that this arrangement makes the forward and backward movement smooth and avoids jamming.

[0043] Furthermore, the power input end 31 is a drive gear, which meshes with and connects to the gear transmission system;

[0044] Alternatively, the power input terminal 31 can be an optical shaft, which is directly connected to a hollow shaft servo motor via a coupling. The advantage of this is that the power input terminal 31 can generate a stable power input.

[0045] Furthermore, an axial inlet 36 is provided between the guide arc surface 34 and the guide slide 33.
