[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figure 1 and Figure 2The utility model discloses a charging connector structure of an aircraft, which includes: a fixing seat 1, a floating plate 2, a male head 3, a radial spherical bearing 5, and a female head 4 is provided on the aircraft. The male head 3 is used to be plugged into the female head 4 along the Z-axis direction to realize charging of the aircraft. In order to facilitate the plugging of the male head 3, a bell mouth 41 may be provided on the female head 4, and the cross-sectional area of ​​the bell mouth 41 gradually increases in the direction toward the male head 3, wherein a conductive pin is embedded in the female head 4, and a conductive spring pin is embedded in the male head 3, and the conductive spring pin contacts the conductive pin to conduct electricity, so as to ensure the charging contact pressure.

[0029] The fixed seat 1 is used as a bearing member to support the floating plate 2 and the male head 3. The fixed seat 1, the floating plate 2 and the male head 3 are stacked in sequence. To realize the plane floating of the male head 3, the floating plate 2 is relatively slidably connected with the fixed seat 1 along the X-axis direction. The male head 3 is provided with a connecting block 32, and the connecting block 32 is relatively slidably connected with the floating plate 2 along the Y-axis direction. In this way, the male head 3 can be arbitrarily adjusted relative to the fixed seat 1 on the XY plane (that is, on the plane perpendicular to the plugging direction of the male head 3) through the floating plate 2; the fixed seat 1 is provided with A first through hole 11 and a second through hole 21 are provided on the floating plate 2. The second through hole 21 connects the first through hole 11 with the inner cavity 31 of the male head 3 for wiring, thereby realizing the hiding of the wires. The radial spherical bearing 5 is connected to the fixing seat 1. The radial spherical bearing 5 can enable the entire head of the charging connector structure to deflect within a certain range in three-dimensional space, so as to adapt to the deflection of the position of the female head 4 and ensure contact adaptability. Also, in order to facilitate wiring, a third through hole 51 connecting to the first through hole 11 is provided on the radial spherical bearing 5.

[0030] When the charging connector structure is applied to equipment such as a hangar or an aircraft carrier platform, the charging connector structure can be installed as a whole on a mounting seat. Specifically, the fixed outer ring of the radial spherical bearing 5 can be fixedly connected to the mounting seat, and the wires connected to the male connector 3 can enter the interior of the hangar or the interior of the aircraft carrier platform through the inner cavity 31, the second through hole 21, the first through hole 11, and the third through hole 51 to be connected to the power supply unit, and then cooperate with the actuator. The actuator can drive the mounting seat to move, and then drive the fixed seat 1 to move along the Z-axis direction through the radial spherical bearing 5. Combined with the arbitrary adjustment of the male connector 3 relative to the fixed seat 1 on the XY plane, the floating connection between the charging connector structure and the aircraft is realized, ensuring full contact and reliable charging. The hiding of the wires facilitates the lifting action during application, and the wires will not be pulled, exposed to the sun, interfered with, etc. due to the exposure of the wires. It has good protection performance and is beautiful, and can be suitable for indoor and outdoor charging.

[0031] Specifically, the first through hole 11 passes through the middle of the fixed seat 1 along the Z-axis direction, the second through hole 21 passes through the middle of the floating plate 2 along the Z-axis direction, and the third through hole 51 passes through the middle of the radial spherical bearing 5 along the Z-axis direction. Preferably, the sizes of the first through hole 11, the second through hole 21, and the third through hole 51 are all larger than the movable range of the male head 3 relative to the fixed seat 1 in the XY plane, so as to prevent the wires from being clamped.

[0032] See also Figures 1 to 3 In order to prevent the uncontrolled rotation of the fixed seat 1 relative to the radial spherical bearing 5, which may cause the wires to twist and entangle, in the present embodiment, the fixed seat 1 is also provided with an anti-rotation member 14 for limiting the position against the external mounting seat, and the anti-rotation member 14 is used to limit the range of rotation of the fixed seat 1 relative to the radial spherical bearing 5 around the Z-axis direction. Specifically, the anti-rotation member 14 includes at least one anti-rotation screw, which protrudes from the fixed seat 1 in the direction away from the floating plate 2. When in use, a corresponding limiting groove may be provided on the mounting seat, and the anti-rotation screw extends into the limiting groove and moves within the range limited by the limiting groove. Preferably, the rotation angle range of the fixed seat 1 relative to the radial spherical bearing 5 around the Z-axis direction is within 45 degrees, and more preferably, the rotation angle range is within 30 degrees.

[0033] See also Figure 2 and Figure 3 In order to achieve relative sliding and restriction between the floating plate 2 and the fixed seat 1, in this embodiment, a penetrating first slide groove 12 is provided on the fixed seat 1, and at least two first slide grooves 12 are provided. The two first slide grooves 12 are relatively arranged on both sides of the first through-hole 11 along the Y-axis direction. The first slide groove 12 extends along the X-axis direction, and the cross-section of the first slide groove 12 is stepped. It also includes a first limit screw 6, which passes through the first limit screw 6 and is screwed to the floating plate 2. The first limit screw 6 can slide on the first slide groove 12 along the X-axis direction, and the nut of the first limit screw 6 can abut against the step surface of the first slide groove 12. In this way, through the mutual cooperation of the first slide groove 12 and the first limit screw 6, the floating plate 2 can be limited to fit relatively to the fixed seat 1 and cannot be separated, and the movement range of the floating plate 2 in the X-axis direction can be limited. In addition, the nut of the first limit screw 6 can be hidden in the first slide groove 12, so that the first limit screw 6 is hidden, and the smoothness of sliding is not affected by bumps. The structure is simple and the appearance is simple. The double first slide groove 12 can also make the sliding of the floating plate 2 in the X-axis direction smoother.

[0034] See also Figure 3In order to reduce the friction when the floating plate 2 slides relative to the fixed seat 1, preferably, a first ball 7 is provided between the fixed seat 1 and the floating plate 2. Specifically, the side of the fixed seat 1 facing the floating plate 2 is inwardly recessed to form a first groove 13, and the first ball 7 is rollably embedded in the first groove 13, and the first ball 7 also rolls against the side of the floating plate 2 facing the fixed seat 1. Preferably, a plurality of first balls 7 are provided and arranged at intervals around the circumference of the first through hole 11, and correspondingly, a plurality of first grooves 13 are also provided.

[0035] In this way, the first ball 7 is relatively installed on the fixed seat 1 and rolls against the floating plate 2, avoiding interference between the rolling contact trajectory between the first ball 7 and the fixed seat 1 and the first slide groove 12 when the first ball 7 is relatively installed on the floating plate 2, which can effectively reduce the size of the fixed seat 1 and the floating plate 2.

[0036] See also Figure 2 and Figure 3 Based on the same inventive concept and purpose, the connecting block 32 and the floating plate 2 may also adopt the matching mode of the above-mentioned sliding groove, limiting screw and ball.

[0037] Specifically, the connecting block 32 is provided with a penetrating second slide groove 321, and the second slide groove 321 is provided with at least two, and the two second slide grooves 321 are relatively arranged on both sides of the second through hole 21 along the X-axis direction, and the second slide groove 321 extends along the Y-axis direction, and the cross-section of the second slide groove 321 is stepped, and also includes a second limit screw 8, the second limit screw 8 passes through the second slide groove 321 and is screwed to the floating plate 2, the second limit screw 8 can slide on the second slide groove 321 along the Y-axis direction, and the nut of the second limit screw 8 can abut against the step surface of the second slide groove 321. In this way, through the mutual cooperation of the second slide groove 321 and the second limit screw 8, the male head 3 can be limited to fit relatively to the floating plate 2 and cannot be separated, and the movement range of the male head 3 in the X-axis direction can be limited. In addition, the nut of the second limit screw 8 can be hidden in the second slide groove 321, so that the second limit screw 8 is hidden and the smoothness of sliding is not affected by bumps. The structure is simple and the appearance is simple. The double second slide groove 321 can also make the sliding of the male head in the Y-axis direction smoother.

[0038] Similarly, in order to reduce the friction when the male head 3 slides relative to the floating plate 2, preferably, a second ball 9 is provided between the connecting block 32 and the floating plate 2. Specifically, the side of the connecting block 32 facing the floating plate 2 is inwardly recessed to form a second groove 322, and the second ball 9 is rollably embedded in the second groove 322, and the second ball 9 also rolls against the side of the floating plate 2 facing the connecting block 32. Preferably, a plurality of second balls 9 are provided and are relatively arranged at both ends of the second slide groove 321 along the Y-axis direction, and correspondingly, a plurality of second grooves 322 are also provided.

[0039] In this way, the second ball 9 is relatively installed on the connecting block 32 and rolls against the floating plate 2, avoiding interference between the rolling contact trajectory between the second ball 9 and the connecting block 32 and the second slide groove 321 when the second ball 9 is relatively installed on the floating plate 2, which can effectively reduce the size of the connecting block 32 and the floating plate 2.

[0040] In the above scheme, rolling friction is achieved by means of balls. It is only necessary to drill a first groove 13 on the fixed seat 1 and a second groove 322 on the connecting block 32. Then, the first limit screw 6 is used to clamp the first ball 7 between the fixed seat 1 and the floating plate 2. The second limit screw 8 is used to clamp the second ball 9 between the connecting block 32 and the floating plate 2. The structure is simple, the processing and assembly are convenient, and the overall cost is low.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
