Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an anti-vibration connector for an unmanned aerial vehicle (UAV). Background Art

[0002] Drones are typically placed in hangars to facilitate remote automated control. The drone is typically equipped with a plug connector, and the hangar is equipped with a socket connector. This allows the drone to dock with the socket connector when it automatically returns to the hangar, ensuring the drone's continued flight.

[0003] Existing connectors, such as patent document CN220122185U, disclose a modular connector comprising a plug assembly and a receptacle assembly. The plug assembly comprises a plug frame module, and the receptacle assembly comprises a receptacle frame module. The plug frame module is provided with a guide hole, and the receptacle frame module is provided with a locating pin. The locating pin slides in and out of the guide hole to achieve plug-in mating of the plug and receptacle assemblies. However, when this connector is used in drones, due to the vibrations generated by the drone, uneven wear occurs when the locating pin and the guide hole are plugged in. After prolonged use, the wear between the locating pin and the guide hole is significant, which can easily lead to inaccurate positioning. Summary of the Invention

[0004] Based on this, it is necessary to provide an anti-vibration connector for drones to address the current technical problem that positioning pins and guide holes are prone to eccentric wear, resulting in inaccurate positioning.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A vibration-resistant connector for a drone, comprising a socket frame and a plug frame; a positioning assembly is provided on the plug frame, the positioning assembly comprising an integrally formed positioning pin and a driving cylinder, the positioning pin is located at the center of the driving cylinder, and a plurality of positioning columns extending radially thereof are provided on the inner circumference of the driving cylinder; a guide assembly is provided on the socket frame, the guide assembly comprising a guide sleeve, the axis of the guide sleeve extending in the up-down direction, a guide hole provided inside the guide sleeve, and a driving groove provided on the outer circumference of the guide sleeve, the driving groove comprising a plurality of alternately arranged first slide grooves and second slide grooves, the first slide grooves and the second slide grooves Both are inclined grooves, and the two ends of the first groove are respectively connected to the adjacent second grooves; when the plug frame and the socket frame are docked, the positioning pin is inserted into the guide hole, and the driving cylinder and the guide sleeve are coaxially plugged into each other, so that the positioning column slides along the first groove. At this time, the guide sleeve will not rotate, so that the driving cylinder rotates around the first direction to drive the positioning pin to rotate synchronously; when the plug frame and the socket frame are separated, the positioning pin is pulled out of the guide hole, and the driving cylinder and the guide sleeve are disengaged from each other, so that the positioning column slides along the second groove. At this time, the driving cylinder will not rotate, so that the guide sleeve rotates around the first direction, and the first direction is the circumferential direction around the axis of the guide sleeve.

[0007] Furthermore, the guide hole includes a tapered guide hole and a circular hole. The tapered guide hole is located at one end of the circular hole close to the positioning pin. A spring piece is provided in the circular hole and is evenly distributed around the circumference of the circular hole.

[0008] Furthermore, the positioning column includes a sleeve and a positioning rod. The sleeve is fixedly arranged on the inner circumference of the driving cylinder. The positioning rod can slide radially along the driving cylinder relative to the sleeve. A first spring is provided between the sleeve and the positioning rod. The first spring makes the positioning rod tend to detach from the sleeve.

[0009] Furthermore, the positioning assembly also includes a fixed cylinder, which is detachably fixed on the plug frame, and a first one-way gear ring is provided on the end face of the fixed cylinder. A second one-way gear ring is provided on the end face of the driving cylinder away from the guide sleeve, and the second one-way gear ring can only rotate in the first direction relative to the first one-way gear ring.

[0010] Furthermore, the guide assembly also includes a first positioning plate and a first positioning sleeve. The first positioning plate is detachably fixed on the socket frame, and a third one-way gear ring is provided on the first positioning plate. The first positioning sleeve is used to detachably install the guide sleeve on the first positioning plate. A fourth one-way gear ring is provided on the end face of the guide sleeve away from the positioning pin, and the fourth one-way gear ring can only rotate in the first direction relative to the third one-way gear ring.

[0011] Furthermore, a floating component is provided on the socket frame. The floating component corresponds to the guide component one by one and is arranged adjacent to each other. A positioning screw is provided in the floating component. The floating component enables the socket frame to move relative to the positioning screw.

[0012] Furthermore, the floating assembly includes a coaxially arranged mounting seat and a sliding ring, the sliding ring is located above the mounting seat, and a plurality of circular rings are provided between the sliding ring and the mounting seat. The plurality of circular rings are stacked along the axial direction of the mounting seat and form a central overlapping area. The positioning screw is located in the central overlapping area. Each circular ring is connected to a guide column through a second spring. The second spring is a compression spring. The guide column extends along the axial direction of the mounting seat. The sides of the mounting seat opposite to the sliding ring are provided with rotation grooves. The upper and lower ends of the guide column can slide along the two rotation grooves respectively, thereby changing the area size of the central overlapping area.

[0013] Furthermore, the floating assembly also includes a second positioning plate and a second positioning sleeve. The second positioning plate is detachably fixed on the socket frame, and the second positioning sleeve is fixed above the second positioning plate. The mounting seat and the sliding ring are located between the second positioning plate and the second positioning sleeve. The sliding ring can slide in the up and down directions relative to the second positioning sleeve, and the sliding ring and the second positioning sleeve are anti-rotationally engaged.

[0014] Furthermore, the rotating groove includes a first rotating groove and a second rotating groove, the first rotating groove is arranged close to the ring relative to the second rotating groove, the first rotating groove extends radially along the mounting seat, and the second rotating groove is arranged inclined relative to the first rotating groove. The guide column slides along the second rotating groove to drive the mounting seat to rotate relative to the second positioning plate.

[0015] Furthermore, a fifth one-way gear ring is provided on the side of the mounting seat away from the sliding ring, and a sixth one-way gear ring is provided on the second positioning plate. The fifth one-way gear ring and the sixth one-way gear ring are both elastic gear rings; when the mounting seat rotates relative to the second positioning plate, the fifth one-way gear ring and the sixth one-way gear ring can rotate relative to each other.

[0016] The beneficial effects of the present invention are:

[0017] The anti-vibration connector for the drone provided by the present invention has the following characteristics: first, each time the positioning assembly and the guide assembly are plugged in and matched, the positioning pin and the guide sleeve can be rotated at a certain angle, so that the wear position between the positioning pin and the guide hole will be replaced, avoiding long-term wear on the same position and extending the service life; at the same time, the wear position is evenly distributed in the circumferential direction of the positioning pin and the guide sleeve, avoiding affecting the positioning accuracy.

[0018] Second, the floating assembly allows the socket frame to have a certain floating space in both the circumferential and axial directions of the positioning screw, thereby increasing the floating range and ensuring that the guide sleeve on the socket frame and the positioning pin on the plug frame can be smoothly plugged in and matched.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0042] like Figures 1 to 18As shown, an anti-vibration connector for a drone provided by an embodiment of the present invention includes a socket frame 100 and a plug frame 500; a positioning assembly 400 is provided on the plug frame 500, and the positioning assembly 400 includes a positioning pin 404 and a driving cylinder 405 that are integrally formed, the positioning pin 404 is located at the center of the driving cylinder 405, and a plurality of positioning columns extending radially thereof are provided on the inner circumference of the driving cylinder 405; a guide assembly 300 is provided on the socket frame 100, and the guide assembly 300 includes a guide sleeve 301, the axis of the guide sleeve 301 extends in the up-down direction, a guide hole 308 is provided inside the guide sleeve 301, and a driving groove 307 is provided on the outer circumference of the guide sleeve 301, and the driving groove 307 includes a plurality of first slide grooves 3071 and second slide grooves 3071 that are alternately arranged. 072, the two ends of the first slide groove 3071 are respectively connected to the adjacent second slide groove 3072; when the plug frame 500 and the socket frame 100 are docked, the positioning pin 404 is inserted into the guide hole 308, and the drive cylinder 405 is coaxially plugged into the guide sleeve 301, so that the positioning column slides along the first slide groove 3071. At this time, the guide sleeve 301 does not rotate, so that the drive cylinder 405 rotates around the first direction to drive the positioning pin 404 to rotate synchronously; when the plug frame 500 and the socket frame 100 are separated, the positioning pin 404 is pulled out of the guide hole 308, and the drive cylinder 405 and the guide sleeve 301 are separated from each other, so that the positioning column slides along the second slide groove 3072. At this time, the drive cylinder 405 does not rotate, so that the guide sleeve 301 rotates around the first direction. The first direction is the circumferential direction around the axis of the guide sleeve 301. In this embodiment, the first direction is Figure 13 Counterclockwise when viewing from top to bottom.

[0043] There are two positioning assemblies 400 on the plug frame 500 , which are respectively located at the two ends of the length direction of the socket frame 100 . There are also two guide assemblies 300 on the socket frame 100 .

[0044] like Figure 13 As described above, the first chute 3071 and the second chute 3072 are both inclined chute, and the angle between the first chute 3071 and the axis of the guide sleeve 301 is smaller than the angle between the second chute 3072 and the axis of the guide sleeve 301. The positioning post enters from the connecting position between the first chute 3071 and the second chute 3072 on the end surface of the guide sleeve 301, and then slides along the first chute 3071. When the positioning post slides to the other connecting position between the first chute 3071 and the second chute 3072, the driving cylinder 405 and the guide sleeve 301 are no longer close to each other. At this time, the positioning pin 404 is inserted into the guide hole 308, and then the driving cylinder 405 and the guide sleeve 301 are disengaged, allowing the positioning post to slide along the second chute 3072.

[0045] In this way, each time the positioning assembly 400 and the guide assembly 300 are plugged in and matched, the positioning pin 404 and the guide sleeve 301 can be rotated at a certain angle, so that the wear position between the positioning pin 404 and the guide hole 308 will be replaced, avoiding long-term wear on the same position and extending the service life; at the same time, the wear position is evenly distributed in the circumferential direction of the positioning pin 404 and the guide sleeve 301, avoiding affecting the positioning accuracy.

[0046] like Figure 14 As shown, the guide hole 308 includes a tapered guide hole and a circular hole. The tapered guide hole is located at one end of the circular hole close to the positioning pin 404. The circular hole is provided with a spring piece 306, and the spring piece 306 is evenly distributed around the circumference of the circular hole.

[0047] The tapered guide hole facilitates the positioning pin 404 to be guided into the circular hole when blindly inserting the positioning pin 404 into the guide hole 308. The spring piece 306 prevents the positioning pin 404 from being easily separated from the circular hole, thereby ensuring the stability of the connection.

[0048] like Figure 16 As shown, the positioning column includes a sleeve 402 and a positioning rod 403. The sleeve 402 is fixedly mounted on the inner circumference of the drive cylinder 405. The positioning rod 403 can slide relative to the sleeve 402 along the radial direction of the drive cylinder 405. A first spring is provided between the sleeve 402 and the positioning rod 403. The first spring causes the positioning rod 403 to have a tendency to separate from the sleeve 402. In this way, when a certain degree of deflection occurs during the insertion of the positioning pin 404 and the guide hole 308, the positioning column can still enter the drive groove 307 and slide along the drive groove 307, so that there is a certain amount of movable space between the positioning assembly 400 and the guide assembly 300 to accommodate blind insertion of the connector.

[0049] like Figure 15 、 Figure 16 and Figure 18 As shown, the positioning assembly 400 also includes a fixed cylinder 401, which is detachably fixed on the socket frame 100. A first one-way gear ring 406 is provided on the end face of the fixed cylinder 401, and a second one-way gear ring 407 is provided on the end face of the driving cylinder 405 away from the guide sleeve 301. The second one-way gear ring 407 can only rotate in the first direction relative to the first one-way gear ring 406.

[0050] like Figures 12 to 14As shown, the guide assembly 300 also includes a first positioning plate 303 and a first positioning sleeve 302. The first positioning plate 303 is detachably fixed on the socket frame 100, and a third one-way gear ring 304 is provided on the first positioning plate 303. The first positioning sleeve 302 is used to detachably install the guide sleeve 301 on the first positioning plate 303. A fourth one-way gear ring 305 is provided on the end face of the guide sleeve 301 away from the positioning pin 404. The fourth one-way gear ring 305 can only rotate relative to the third one-way gear ring 304 in the first direction. The first one-way gear ring 406, the second one-way gear ring 407, the third one-way gear ring 304 and the fourth one-way gear ring 305 are all composed of annularly distributed sawtooth pieces, and the sawtooth pieces have vertical surfaces and inclined surfaces. The first direction is Figure 12 Counterclockwise when viewing from top to bottom.

[0051] Thus, when the positioning pin 404 is inserted into the guide hole 308, the drive cylinder 405 and the guide sleeve 301 are coaxially plugged together, causing the positioning post to slide along the first sliding groove 3071. The positioning post causes the guide sleeve 301 to rotate in a direction opposite to the first direction. Since the guide sleeve 301 cannot rotate in a direction opposite to the first direction, the drive cylinder 405 rotates in the first direction. When the positioning pin 404 is removed from the guide hole 308, the positioning post slides along the second sliding groove 3072. Since the positioning post cannot drive the drive cylinder 405 to rotate in a direction opposite to the first direction, the guide sleeve 301 rotates in the first direction, achieving separation of the drive cylinder 405 from the guide sleeve 301.

[0052] like Figures 2 to 8 As shown, the socket frame 100 is further provided with a floating component 200 , which corresponds to and is adjacent to the guide component 300 . A positioning screw 201 is provided in the floating component 200 , and the floating component 200 enables the socket frame 100 to move relative to the positioning screw 201 .

[0053] The positioning screws 201 are used to secure the socket frame 100 in the drone hangar. Because drones vibrate during operation, the floating assembly 200 creates a certain amount of floating space between the positioning screws 201 and the socket frame 100, allowing the socket frame 100 to deflect relative to the positioning screws 201, thereby allowing the guide assembly 300 and the positioning assembly 400 on the socket frame 100 to dock more smoothly.

[0054] The floating assembly 200 includes a coaxially arranged mounting seat 207 and a sliding ring 203. The sliding ring 203 is positioned above the mounting seat 207. Multiple circular rings 206 are positioned between the sliding ring 203 and the mounting seat 207. The rings 206 are stacked axially along the mounting seat 207 to form a central overlap region. The positioning screw 201 is located in the central overlap region. Each circular ring 206 is connected to a guide post 204 via a second spring 205. The guide posts 204 extend axially along the mounting seat 207. The sides of the mounting seat 207 opposite the sliding ring 203 are each provided with a rotation groove 209. The upper and lower ends of the guide posts 204 can slide along the two rotation grooves 209, respectively, thereby varying the size of the central overlap region. The second springs 205 are compression springs that tend to stagger the rings 206, thereby reducing the area of ​​the central overlap region.

[0055] The size of the central overlapping region changes, so that the distance between the inner wall of the central overlapping region and the positioning screw 201 changes, thereby allowing the socket frame 100 to have a certain floating space in the circumferential direction of the positioning screw 201 to adapt to the offset of the socket frame 100.

[0056] Furthermore, the floating assembly 200 also includes a second positioning plate 208 and a second positioning sleeve 202. The second positioning plate 208 is detachably fixed on the socket frame 100. The second positioning sleeve 202 is fixed above the second positioning plate 208. The mounting seat 207 and the sliding ring 203 are located between the second positioning plate 208 and the second positioning sleeve 202. The sliding ring 203 can slide in the up and down directions relative to the second positioning sleeve 202, and the sliding ring 203 is engaged with the second positioning sleeve 202 to prevent rotation.

[0057] The outer periphery of the sliding ring 203 is provided with splines, and the interior of the second positioning sleeve 202 is provided with a keyway, and the splines and keyway slide in conjunction. The sliding ring 203 slides relative to the second positioning sleeve 202, allowing the floating assembly 200 to have a certain floating space in the axial direction of the positioning screw 201, thereby expanding the floating range.

[0058] An annular step is provided on the outside of the guide sleeve 301 , and the second positioning sleeve 202 is engaged with the annular step in the up and down directions, thereby limiting the up and down movement of the guide sleeve 301 .

[0059] Furthermore, the rotating groove 209 includes a first rotating groove 2091 and a second rotating groove 2092. The first rotating groove 2091 is arranged close to the ring 206 relative to the second rotating groove 2092. The first rotating groove 2091 extends radially along the mounting seat 207. The second rotating groove 2092 is inclined relative to the first rotating groove 2091. The guide column 204 slides along the second rotating groove 2092 to drive the mounting seat 207 to rotate relative to the second positioning plate 208.

[0060] Initially Figure 9 In the first state shown, the central overlapping area of ​​the plurality of rings 206 is the smallest, and the guide post 204 is located in the first rotation groove 2091. When the socket frame 100 moves a short distance relative to the positioning screw 201, as shown in FIG. Figure 10 In the second state shown, the positioning screw 201 hits the ring 206, compressing the second spring 205, thereby increasing the area of ​​the central overlapping area formed by the multiple circles, thereby increasing the distance between the socket frame 100 and the positioning screw 201. When the socket frame 100 moves a large distance relative to the positioning screw 201, as shown in FIG. Figure 11 In the third state shown, the impact force of the positioning screw 201 on the ring 206 is relatively large, causing the guide column 204 to enter the second rotation groove 2092 along the first rotation groove 2091, thereby enabling the mounting seat 207 to rotate, so that the area of ​​the central overlapping zone formed by the multiple rings 206 reaches the maximum.

[0061] A fifth one-way gear ring 211 is provided on the side of the mounting seat 207 away from the sliding ring 203, and a sixth one-way gear ring 210 is provided on the second positioning plate 208. The fifth one-way gear ring 211 and the sixth one-way gear ring 210 are both elastic gear rings; when the mounting seat 207 rotates relative to the second positioning plate 208, the fifth one-way gear ring 211 and the sixth one-way gear ring 210 can rotate relative to each other.

[0062] When the guide post 204 first enters the second rotation groove 2092, the mounting seat 207 cannot overcome the resistance between the fifth one-way gear ring 211 and the sixth one-way gear ring 210, and thus the mounting seat 207 does not rotate. After the guide post 204 enters the second rotation groove 2092 and moves a certain distance, the mounting seat 207 is able to overcome the resistance between the fifth one-way gear ring 211 and the sixth one-way gear ring 210 and thus rotate.

[0063] In other embodiments, the fifth one-way gear ring 211 and the sixth one-way gear ring 210 may be replaced by friction plates.

[0064] like Figure 17 and Figure 18 As shown, the socket frame 100 includes a first fixing plate 101 and a second fixing plate 102, which are detachably connected by bolts. The side of the plug frame 500 is detachably mounted with an ear plate by bolts, and the fixing cylinder 401 is detachably mounted on the ear plate.

[0065] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0066] The drone enters the hangar, aligns the locating pin 404 with the guide hole 308 of the guide sleeve 301, and then brings the socket frame 100 and the plug frame 500 closer to each other. As the locating pin 404 is inserted into the guide hole 308, the driving cylinder 405 is coaxially plugged into the guide sleeve 301, causing the locating column to slide along the first slide groove 3071, so that the driving cylinder 405 rotates in the first direction to drive the locating pin 404 to rotate synchronously, thereby changing the wear position between the locating pin 404 and the inner wall of the guide hole 308.

[0067] When there is a deviation during the docking process between the positioning pin 404 and the guide hole 308, the socket frame 100 will move relative to the positioning screw 201, causing the positioning screw 201 to hit multiple rings 206. The area of ​​the central overlapping area formed by the multiple rings 206 increases, so that there is a certain floating space between the positioning screw 201 and the socket frame 100, which facilitates the smooth docking of the positioning pin 404 and the guide hole 308.

[0068] When the drone leaves the hangar, the positioning pin 404 is pulled out from the guide hole 308, separating the socket frame 100 from the plug frame 500. At this time, the driving cylinder 405 and the guide sleeve 301 are disengaged from each other, causing the positioning column to slide along the second slide groove 3072, thereby driving the guide sleeve 301 to rotate in the first direction, and again changing the wear position between the inside of the guide hole 308 and the positioning pin 404.

[0069] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0070] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
