Description

Technical Field

[0001] This utility model relates to the field of fluid connection in thermal management systems, and in particular to a novel power input mechanism for a telescopic fluid connector. Background Technology

[0002] In the field of new energy flight equipment, especially electric flying cars, the power supply for these devices is a new energy battery (such as a lithium-ion battery). 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 battery, reaching temperatures of 60 degrees Celsius or higher. However, the optimal operating temperature range for batteries is 10 to 45 degrees Celsius. Therefore, a fluid connector is needed to connect an external liquid cooling source and internal cooling channels to cool the battery to its optimal temperature range. Currently, the fluid connector is inserted and removed by the operator through axial pushing. The question is... The problems are as follows: First, it requires considerable gripping and pushing force, making operation inconvenient and difficult to quickly align and install for rapid connection and disconnection. It also lacks 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. Second, 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

[0011] In some embodiments, the mounting base includes a circular rear base plate and a front connector. The rear end of the front connector is open to form a mounting cavity. The gap between the rear base plate and the front connector forms a circumferential opening. The front end of the output shaft extends into the middle tube hole of the socket end.

Detailed Implementation

[0016] 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.

[0017] Figures 1 to 9 The figure schematically illustrates a novel power input mechanism for a telescopic fluid connector according to one embodiment of the present invention. As shown, the novel power input mechanism for the telescopic fluid connector includes: a fixed base 1, a power input section 2, a plurality of planetary gears 3, and a power output section 4; The fixing base 1 has a circumferential opening 101 in the middle and an installation cavity 100 communicating with the circumferential opening 101. The two sides of the fixing base 1 are symmetrically connected to the liquid inlet terminal 01, and the center of its front cavity wall has a first through hole 102. The power input unit 2 includes a power wheel 21, a hollow turntable 20 integrally connected to the power wheel 21, and a drive gear ring 22 fixed to the front end wall of the turntable 20. The turntable 20 is located at the circumferential opening 101 and the drive gear ring 22 is rotatably connected to the inner ring wall of the mounting cavity 100. Preferably, the power input unit 2 also includes a plurality of radially arranged radial connecting arms 23. The outer end of the connecting arm 23 is threaded to the power wheel 21 and the inner end is threaded to the turntable 20. The arrangement of the radially arranged connecting arms 23 makes the overall weight light and easy to hold, while also facilitating the arrangement of other components.

[0018] Multiple vertical planetary gears 3 are arranged in a circumferential array and fixedly connected to the side wall of the mounting cavity 100. The large-diameter input tooth end 31 at the rear end of the planetary gear 3 meshes with the outer active gear ring 22, and the small-diameter output tooth end 32 at the front end of the planetary gear 3 meshes with the passive gear 41. The power output unit 4 includes an output shaft 40 and a driven gear 41 vertically connected to the rear end of the output shaft 40. The middle section of the output shaft 40 is rotatably connected to the first through hole 102.

[0019] The drive wheel 21 can be manually or mechanically rotated to make the drive gear ring 22 rotate the large diameter input end 31 of the planetary gear 3, thereby causing the small diameter output end 3 to drive the driven gear 41 to rotate, so that the output shaft 40 can input rotational power with a suitable transmission ratio.

[0020] This novel telescopic fluid connector's power input mechanism utilizes a handwheel rotation and a new multi-gear module connection structure to convert operating and installation forces, enabling labor-saving operation. Its advantages include: First, the labor-saving structure allows for convenient and quick operation, achieving lightweight, fast, and precise connection and disconnection of the fluid connector. This allows the battery pack to cool rapidly and effectively to its optimal operating temperature range, avoiding overheating and degradation caused by prolonged exposure to excessively high temperatures, thus extending its service life. Second, after the electric vehicle lands, rapid cooling enables the electric flying car to quickly generate electricity for reuse. It features excellent thermal management and rapid charging at suitable temperatures, eliminating the need for long waiting times and facilitating quick charging and restart, resulting in high equipment utilization. Third, this structure is directly integrated into the existing structure without altering its layout, resulting in a compact overall size and small volume. Fourth, multiple planetary gears 3 ensure uniform force distribution across the entire power transmission structure. Fifth, the planetary gears 3 employ a double-layer design with a large-diameter input tooth end 31 and a small-diameter output tooth end 32, optimizing the transmission ratio and making transmission lighter and more stable without interfering with the arrangement of other structures.

[0021] Furthermore, the drive wheel 21 is a ring structure with a circular cross-section. The drive wheel 21 has multiple radially arranged slits 211, and the front face of the turntable 20 has multiple circumferentially arranged connecting grooves 201. The outer end of the flat connecting arm 23 is located in the radially arranged slits 211, and the inner end is located in the connecting grooves 201. The connection points are fixedly connected by threaded components. The beneficial effects are: the radially arranged slits 211 and the connecting grooves 201 allow for a thinner overall thickness, optimizing the product volume, while also facilitating high-precision installation and fixing.

[0022] Preferably, each first threaded component 26 passes through the through hole of the turntable 20 and the through hole at the inner end of the connecting arm 23 and is screwed into the threaded hole of the drive gear ring 22, thereby fixing the three together as a whole. The advantages are: this arrangement uses a shared set of connectors, saving parts, reducing costs, and optimizing product size.

[0023] Furthermore, the planetary gear 3 includes an input tooth end 31 and an output tooth end 32 coaxially arranged. The output tooth end 32 is integrally connected to the front side of the input tooth end 31, and the central shaft hole of the output tooth end 32 is rotatably connected to the end shaft 103 in the mounting cavity 100. The pitch circle diameter of the driven gear 41 is larger than that of the output tooth end 32 and smaller than that of the input tooth end 31. The pitch circle diameter of the input tooth end 31 is smaller than that of the driving gear ring 22. The beneficial effect is that the transmission ratio of the planetary gear 3 configured in this way is more optimized, and the transmission is more convenient and stable.

[0024] The outer surface of the output tooth end 32 is provided with a first shaft hole 33. The inner ring wall of the mounting cavity 100 is symmetrically and vertically connected with multiple C-shaped receiving rings 104 with inner openings and multiple end shafts 103. Each end shaft 103 is coaxially arranged in the fixed end ring 106. Its beneficial effect is that this arrangement can achieve high-precision fixation.

[0025] Preferably, there are two planetary gears 3, with the two liquid inlet terminals 01 symmetrically fitted with the fixing base 1, and the two planetary gears 3 symmetrically arranged above and below the center of the two liquid inlet terminals 01. The beneficial effect is that the symmetrical arrangement of the planetary gears 3 ensures that the force transmission structure is evenly distributed, while not interfering with the arrangement of other structures.

[0026] Preferably, the planetary gear 3 further includes a large-diameter gear body 30. One planetary gear 3's gear body 30 is integrally formed at the rear end of the input tooth end 31, and the front end of the input tooth end 31 is integrally formed at the output tooth end 32. The other opposing planetary gear 3's gear body 30 has its output tooth end 32 and input tooth end 31 integrally formed at its front and rear ends, respectively, so that the two input tooth ends 31 respectively mesh with the front and rear ends of the driving gear ring 22. Its beneficial effect is that the staggered structure allows it to bear a larger torque.

[0027] Furthermore, the fixed base 1 includes a circular rear base plate 11 and a front coupling 10. The rear end of the front coupling 10 is open to form a mounting cavity 100. A second threaded component 27 passes through the rear base plate 11 and the shim column 12 and is threaded to the front coupling 10, thereby forming a circumferential opening 101 between the rear base plate 11 and the front coupling 10. The rear end of the rear base plate 11 is fixedly connected to the front flange plate of the hydraulic pipe 02 by a threaded component. The front end of the front coupling 10 is fixedly connected to the socket end by a threaded component. The front end of the output shaft 40 extends into the middle pipe hole of the socket end. The front and rear ends of the turntable 20 are fitted against the front and rear end walls of the circumferential opening 101. Preferably, it also includes an inner guide plate 5. The inner guide plate 5 is located inside the turntable 20 and is threaded to the front cavity wall of the mounting cavity 100. The liquid inlet terminal 01 is sleeved in the clearance opening 51 of the inner guide plate 5. The turntable 20 is sleeved on the outer circular surface of the inner guide plate 5 with a small gap. The second threaded component 27 passes through the intermediate through hole of the rear base plate 11, the shim post 12, and the inner guide plate 5, and is threaded to the threaded boss 105 of the front coupling 10. Its advantages are: the structure is simple and can achieve good installation and fixation.

[0028] Furthermore, at least one vertical tube 200 is integrally formed at the rear end of the turntable 20. An axial spring 25 and a locking steel ball 24 are sleeved inside the vertical tube 200. A conical locking hole 111 is provided at the rear end of the rear base plate 11. The vertical tube 200 is fitted to or gapped to the rear base plate 11. The locking steel ball 24 elastically presses against the conical locking hole 111. The beneficial effect of this setting is that it ensures the rotation of the turntable 20 after it is installed in place, while avoiding the phenomenon of self-rotation when not in use, and does not increase the installation force when in use.

[0029] Furthermore, the passive gear 41 is integrally connected to the rear end of the output shaft 40, and the middle section of the output shaft 40 and the first through hole 102 are slidably configured with equal diameter, or a copper sleeve or linear bearing is provided between the two. The beneficial effect is that this configuration ensures good linear motion.

[0030] Furthermore, the front end of the circumferential wall of the output shaft 40 is provided with a spiral guide groove 42. The plug end is installed at the battery pack end of the device. A resistance post is integrally provided in the shaft hole of the plug end. The spiral guide groove 42 slidably connects to the resistance post to form a lead screw and nut pair. The resistance post and the plug socket end are fixedly set. The output shaft 40 rotates and extends and retracts linearly forward, thereby driving the plug end to move linearly to plug and unplug the socket end, and connecting the male and female ends of the fluid connector. Its beneficial effect is that this setting can make the connection more effortless.

[0031] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
