[0009] Optionally, the pressing mechanism is provided with a reset button, which is kinetically connected to the connecting end of the snap-fit member; after the reset button is pressed, the reset button drives the movable end of the snap-fit member to move to fit against the side wall of the pressing mechanism, so as to release the snap-fit engagement between the snap-fit member and the snap-fit notch.

The elastic structure applies an elastic reset force to the interface structure. The male connector assembly has an insertion structure. During the mating process between the male and female connector assemblies, even if there are dimensional tolerances in the guide rail and connector during installation, the insertion structure of the male connector, when pressing against the interface structure of the female connector, allows the interface structure to move along a plane perpendicular to the insertion direction. This compensates for the dimensional tolerances in the guide rail and connector installation process, allowing the insertion structure to smoothly extend into the interface structure, avoiding mating difficulties and severe wear caused by connector misalignment.

[0036] Currently, the low-altitude economy, as an emerging industry, is developing rapidly, and transportation devices such as flying cars have also emerged. Flying cars have various configurations. One configuration consists of two parts: a flying body and a land-based body. The land-based body, as a land vehicle, can carry both passengers and the flying body at the same time, while the flying body can dock with and detach from the land-based body to carry passengers in the air.
[0037] Currently, connectors are required for docking between flying and land vehicles. There are currently no connectors specifically designed for docking flying and land vehicles; therefore, connectors in flying cars are typically designed with reference to those used in electric vehicles. These current connectors only ensure a proper connection between the flying and land vehicles. Furthermore, the land vehicle usually has guide rails to guide the flying vehicle during docking, allowing it to smoothly dock with the land vehicle via the connector.
[0038] However, during the docking process between the aircraft and the land-based aircraft, the dimensional and positional tolerances during guide rail installation and connector installation may cause difficulties in docking and wear between the male and female ends of the connector, which not only affects the success rate of docking but also the service life of the connector.
[0039] Therefore, this application proposes a connector, transportation equipment, and charging system to address the impact of geometric tolerances on the mating of the male and female terminals of the connector.
[0040] Reference Figure 1 , Figure 2 and Figure 3In one embodiment of this application, the connector includes a female end assembly 1000 and a male end assembly 2000. The female end assembly 1000 includes a female end body 1100, an interface structure 1200, and an elastic structure 1300. The female end body 1100 is provided with a receiving groove 1110. The interface structure 1200 is disposed in the receiving groove 1110. The outer periphery of the interface structure 1200 is elastically connected to the receiving groove 1110 through the elastic structure 1300. The interface structure 1200 has a degree of freedom to move within a preset range along a plane perpendicular to the insertion direction. The elastic structure 1300 applies an elastic reset force to the interface structure 1200. The male end assembly 2000 is provided with an insertion structure 2100, which is inserted into the interface structure 1200.
[0041] By including a female end assembly 1000 of the connector, a female end body 1100, an interface structure 1200, and an elastic structure 1300, and providing a receiving groove 1110 on the female end body 1100, the interface structure 1200 is disposed within the receiving groove 1110. The outer periphery of the interface structure 1200 is elastically connected to the receiving groove 1110 through the elastic structure 1300, thereby giving the interface structure 1200 a degree of freedom to move within a preset range along a plane perpendicular to the insertion direction, while the elastic structure 1300 applies an elastic reset force to the interface structure 1200; on the male end assembly 2000... An insertion structure 2100 is provided. During the docking process between the male end component 2000 and the female end component 1000, even if there are dimensional and positional tolerances in the guide rail and connector during installation, the insertion structure 2100 of the male end component 2000 can make the interface structure 1200 move within a preset range along a plane perpendicular to the insertion direction when it presses against the interface structure 1200 of the female end component. This offsets the dimensional and positional tolerances in the installation process of the guide rail and connector, allowing the insertion structure 2100 to smoothly extend into the interface structure 1200, avoiding docking difficulties and severe wear of the connector due to misalignment.
[0042] In some embodiments, the male terminal component 2000 may have a mating protrusion extending beyond its main body. This protrusion is annular, and its outer periphery engages with the wall of the receiving groove 1110, thereby enhancing the connection strength after the male terminal component 2000 and the female terminal component 1000 are mated. Furthermore, the insertion structure 2100 of the male terminal component 2000 may be located within the annular area enclosed by the mating protrusion, thus providing partial shielding when the male terminal component 2000 is not mated with the female terminal component 1000. This provides protection for the insertion structure 2100, preventing it from being damaged or deformed due to collisions, thus ensuring proper mating with the interface structure 1200.
[0043] Furthermore, the female end body 1100 can be cuboid in shape and have a first mating surface that mates with the male end component 2000. The male end component 2000 can also be cuboid in shape and have a second mating surface that mates with the female end component 1000. The female end body 1100 and the male end component 2000 can also be configured in other shapes, as long as they have the aforementioned components and functions. The specific shapes and configurations of the female end body 1100 and the male end component 2000 are not limited here. The area of the first mating surface of the female end body 1100 can be larger than that of the second mating surface of the male end component 2000.
[0044] In electric vehicles, the vehicle body and battery are fixed together, eliminating concerns about vibration-induced detachment, stability, reliability, and safety. However, for flying cars, using existing electric vehicle connectors can lead to displacement of the flying vehicle and the ground vehicle during vibrations, causing the male terminal component 2000 and female terminal component 1000 of the connector to become loosely connected or even detach, posing a safety risk. Therefore, this embodiment provides the following implementation methods to address the unreliable connection problem between the male terminal component 2000 and female terminal component 1000 of the connector:
[0045] In the first embodiment, the male end component 2000 facing the female end component 1000 is further provided with an elastic locking structure, and the female end component 1000 is further provided with a locking groove, thereby achieving a locking engagement using the elastic locking structure and the locking groove. Specifically, the elastic locking structure extends into the locking groove, and the elastic locking structure is pressed against the locking groove so that the elastic locking structure and the groove wall of the locking groove form a locking engagement.
[0046] The first embodiment utilizes the deformation of the elastic locking structure under pressure to create an interference fit between the elastic locking structure and the sidewall of the locking groove, generating a frictional locking effect, thereby achieving the locking effect between the male end assembly 2000 and the female end assembly 1000. This embodiment requires a simple structure; the elastic locking structure can be a rod-shaped structure fitted with an elastic material, such as a rubber-coated end.
[0047] In the second embodiment, refer to Figure 1 , Figure 2 and Figure 3The female end component 1000 facing the male end component 2000 is also provided with a snap-fit structure 1400, and the male end component 2000 is also provided with a snap-fit groove 2200. The snap-fit structure 1400 and the snap-fit groove 2200 are used to achieve mutual fixation between the male end component 2000 and the female end component 1000. Specifically, the snap-fit structure 1400 includes a pressing mechanism 1410 and a snap-fit member 1420. The connecting end of the snap-fit member 1420 is kinetically connected to the pressing mechanism 1410. The groove wall of the snap-fit groove 2200 is provided with a snap-fit notch. The snap-fit structure 1400 extends into the snap-fit groove 2200, and the bottom of the snap-fit groove 2200 presses against the pressing mechanism 1410, causing the pressing mechanism 1410 to push out the movable end of the snap-fit member 1420, so that the movable end of the snap-fit member 1420 snaps into the snap-fit notch.
[0048] The second embodiment, by providing a pressing mechanism 1410 and a snap-fit component 1420, when the male end component 2000 is inserted into the female end component 1000, the snap-fit groove 2200 applies axial pressure to the pressing mechanism 1410, causing the movable end of the snap-fit component 1420 to automatically pop out and form a snap-fit engagement with the snap-fit notch. This snap-fit process also requires no manual intervention; simply inserting the male end component 2000 into the snap-fit groove 2200 achieves the effect of insertion and snap-fit locking, making the operation convenient.
[0049] In one optional implementation, the connecting end of the latching member 1420 can be rotatably connected to the pressing mechanism 1410 using a torsion spring. The side wall of the pressing mechanism 1410 is provided with a latching portion that can move after being pressed. When the pressing mechanism 1410 is not pressed, the movable end of the latching member 1420 is engaged with the latching portion, and at this time, the movable end of the latching member 1420 is in contact with the side wall of the pressing mechanism 1410. After the pressing mechanism 1410 is pressed by the latching groove 2200, the latching portion moves to a preset position and releases the latching engagement with the latching member 1420, causing the movable end of the latching member 1420 to pop out, thereby engaging the movable end of the latching member 1420 with the latching notch.
[0050] Furthermore, referring to Figure 2 and Figure 3The pressing mechanism 1410 is equipped with a reset button 1430, which is connected to the connecting end of the snap-fit component. When the reset button 1430 is pressed, it moves the movable end of the snap-fit component to fit against the side wall of the pressing mechanism 1410, thereby releasing the snap-fit engagement between the snap-fit component 1420 and the snap-fit notch. By providing the reset button 1430, the snap-fit engagement between the snap-fit component 1420 and the snap-fit notch can be released, allowing the operator to flexibly adjust the connection and separation of the male end assembly 2000 and the female end assembly 1000. Various transmission connection methods can be used between the connecting ends of the reset button 1430 and the snap-fit component 1420, which are not limited here. For example, the bottom of the reset button 1430 is equipped with a rack, and the connecting end of the snap-fit component 1420 is equipped with a gear, with the reset button 1430 and the snap-fit component 1420 connected by a rack and gear transmission.
[0051] In the third embodiment, the male end component 2000 facing the female end component 1000 is further provided with an electric locking structure, and the female end component 1000 is further provided with a locking groove. This allows for the electric locking structure and the locking groove to be locked together using an electronic control method, achieving a locking engagement between the male end component 2000 and the female end component 1000. Specifically, the electric locking structure includes a main body, a locking pin, and an electric drive device. The side wall of the main body has a first notch, and the locking pin is movably disposed within the first notch. The drive end of the electric drive device is drively connected to the locking pin. The groove wall of the locking groove has a locking notch. The main body extends into the locking groove along the insertion direction, and the electric drive device drives the locking pin to extend out of the first notch, so that the locking pin extends into the locking notch and forms a locking engagement.
[0052] The third embodiment employs an electronic control method, utilizing the transmission end of an electric drive device to extend the locking pin, causing the locking pin to engage with the locking groove, thereby achieving the locking engagement between the male component 2000 and the female component 1000. Compared to manual operation, this electronic control method eliminates the time delay and operational errors caused by manual intervention, achieving millisecond-level locking response, significantly improving connection efficiency and operational convenience. Furthermore, the locking engagement between the locking pin and the locking groove ensures locking reliability and anti-displacement performance, effectively preventing misalignment or displacement between the male component 2000 and the female component 1000.
[0053] All three implementation methods described above can achieve relative fixation of the male and female components. The specific setting can be selected according to actual needs and is not limited here.
[0054] In one embodiment, refer to Figure 4 and Figure 5One of the male end component 2000 and the female end component 1000 is provided with a guide protrusion 3000, and the other of the male end component 2000 and the female end component 1000 is provided with a guide groove 4000. The guide protrusion 3000 and the guide groove 4000 are inserted into each other, thereby using the guiding effect of the guide protrusion 3000 and the guide groove 4000 to guide the male end component 2000 and the female end component 1000 to mate, ensuring normal insertion and engagement of the male end component 2000 and the female end component 1000. As an optional implementation, the guide protrusion 3000 can be configured as a conical structure, with its diameter gradually decreasing along the insertion direction. The guide groove 4000 can be correspondingly configured as a conical groove corresponding to the guide protrusion 3000. This allows the guide protrusion 3000 to have a large positioning error margin in the initial stage of extending into the guide groove 4000, and the positioning error gradually decreases as the guide protrusion 3000 extends into the guide groove 4000, achieving precise guidance.
[0055] Furthermore, in order to ensure that the guide protrusion 3000 and the guide groove 4000 can fully exert their guiding function, the length of the guide protrusion 3000 protruding from the male end component 2000 is greater than the length of the insertion structure 2100 protruding from the male end component 2000. This allows the guide protrusion 3000 to contact the female end component 1000 before the insertion structure 2100 during the insertion process of the male end component 2000 and the female end component 1000, thereby realizing the pilot positioning function of the guide protrusion 3000.
[0056] Furthermore, the male end assembly 2000 and the female end assembly 1000 may be provided with multiple guide protrusions 3000 and multiple guide grooves 4000. The multiple guide protrusions 3000 and multiple guide grooves 4000 correspond one-to-one for guidance and engagement, thereby improving the insertion and engagement accuracy of the male end assembly 2000 and the female end assembly 1000 in various positions, to achieve precise insertion and engagement of the male end assembly 2000 and the female end assembly 1000. As an optional implementation, the guide protrusions 3000 may be configured as guide posts, and the guide grooves 4000 may be configured as corresponding guide holes.
[0057] In one embodiment, refer to Figure 1 and Figure 2The female end body 1100 is also provided with a first sealing ring 1120, which surrounds the outer periphery of the receiving groove 1110. The male end assembly 2000 forms a sealing fit with the female end assembly 1000 through the first sealing ring 1120. The thickness of the first sealing ring 1120 is greater than the degree of freedom of movement of the interface structure 1200. In this embodiment, after the male end assembly 2000 and the female end assembly 1000 form a plug-in fit, the axial force of the male end assembly 2000 and the female end assembly 1000 along the insertion structure 2100 causes the first sealing ring 1120 to perform a sealing function. By making the thickness of the first sealing ring 1120 greater than the degree of freedom of movement of the interface structure 1200, it is ensured that after the interface structure 1200 moves within the range of its degree of freedom of movement when it is plugged into the insertion structure 2100, the first sealing ring 1120 can still provide a sufficient sealing area to seal the male end component 2000 and the female end component 1000 in the mating area after the movement, thus ensuring the reliability of the sealing effect.
[0058] In one embodiment, a second sealing ring is provided on the wall of the receiving groove 1110, and the mating end of the male end component 2000 forms a sealed fit with the female end component 1000 through the second sealing ring; the thickness of the second sealing ring is greater than the degree of freedom of movement of the interface structure 1200. In this embodiment, after the male end component 2000 and the female end component 1000 are inserted into each other, since the second sealing ring is disposed on the groove wall of the receiving groove 1110, the radial force along the mating end when the male end component 2000 is inserted into the receiving groove 1110 causes the second sealing ring to perform a sealing function. In particular, by making the thickness of the second sealing ring greater than the degree of freedom of movement of the interface structure 1200, it is ensured that after the interface structure 1200 moves within the range of the degree of freedom of movement when it is inserted into the insertion structure 2100, the second sealing ring can still provide a sufficient sealing area in the mating area of the male end component 2000 and the female end component 1000 after the movement, so as to seal the male end component 2000 and the female end component 1000, ensuring the reliability of the sealing effect.
[0059] In one embodiment, refer to Figure 1 and Figure 2The insertion structure 2100 includes at least one of a power plug 2110 and a signal plug 2120; correspondingly, the interface structure 1200 includes at least one of a power interface 1210 and a signal interface 1220. Thus, after the male terminal component 2000 mates with the female terminal component 1000 along the insertion direction to form a plug-in engagement, the power plug 2110 can form an electrical connection with the power interface 1210, and the signal plug 2120 can form a communication connection with the signal interface 1220, thereby realizing current supply and / or communication transmission. The power plug 2110 and signal plug 2120 can be configured as pin-like structures, such as power pins and signal pins, while the power interface 1210 and signal interface 1220 can be correspondingly configured as a hole-like power interface 1210 and a hole-like signal interface 1220.
[0060] Taking the pin-shaped power plug 2110 as an example, in order to provide high voltage power, the power plug 2110 may include a high voltage positive power pin and a high voltage negative power pin; at the same time, the power plug 2110 may also include a grounding pin, thereby using the grounding pin to reduce the risk of leakage and eliminate possible interference from weak electromagnetic induction.
[0061] Furthermore, the signal plug 2120 and signal interface 1220 can also adopt interfaces such as VGA interface, D-Sub, etc. The specific configurations of the power plug 2110, signal plug 2120, power interface 1210, and signal interface 1220 are not limited here.
[0062] In one embodiment, the bottom of the receiving groove 1110 has an opening, and the side of the interface structure 1200 facing away from the male terminal component 2000 extends out of the opening, thereby allowing the side of the interface structure 1200 facing away from the male terminal component 2000 to establish a connection with an external power source or signal source. For example, the side of the interface structure 1200 facing away from the male terminal component 2000 can establish an electrical connection and / or communication connection with the power supply terminal of a transportation device or a vehicle-mounted connection port. Correspondingly, the side of the insertion structure 2100 facing away from the female terminal component 1000 can be used to establish an electrical connection and / or communication connection with the flying body in an unmanned aerial vehicle or flying car, thereby enabling electrical and communication connections between different devices using this connector.
[0063] In one embodiment, refer to Figure 1 and Figure 6The elastic structure 1300 includes a plurality of first elastic elements 1310, which are spaced apart along the wall of the receiving groove 1110. One end of the first elastic element 1310 along the elastic extension direction is connected to the wall of the receiving groove 1110, and the other end of the first elastic element 1310 along the elastic extension direction is connected to the outer periphery of the interface structure 1200. The elastic extension direction is perpendicular to the insertion direction, so that when the first elastic element 1310 is compressed or stretched, pressure or tension is mainly applied along the elastic extension direction, so that the interface structure 1200 mainly moves within a preset range along a plane perpendicular to the insertion direction, thereby preventing the interface structure 1200 from coming out of the receiving groove 1110.
[0064] In one preferred embodiment, two adjacent first elastic elements 1310 are equidistantly distributed along the wall of the receiving groove 1110 to provide sufficient elastic adjustment and sufficient elastic reset effect to all parts of the outer periphery of the interface structure 1200. Alternatively, in another embodiment, the first elastic element 1310 can be a spring. Springs have sufficient energy storage and release capabilities and are inexpensive to purchase, thus meeting the elastic connection and elastic reset requirements of this embodiment.
