Referring to fig. 1 and 5, fig. 5 is an exploded view of the driving mechanism 120 and the chucking assembly 130 of fig. 1. The quick release device of the present embodiment includes a mounting assembly 100 and a holder 200. The mounting assembly 100 includes a mounting base 110, a driving mechanism 120 and a clamping assembly 130, the cradle head 200 is slidably connected to the mounting base 110, and after the cradle head 200 slides in place relative to the mounting base 110, the clamping assembly 130 is used to clamp and fix the cradle head 200 on the mounting base 110. The driving mechanism 120 is used for driving the clamping assembly 130, so as to release the clamping state of the holder 200 and the mounting base 110, and the holder 200 is disassembled.

Referring to fig. 1 to 3, fig. 2 is an oblique view of the head 200 of fig. 1, and fig. 3 is an oblique view of the mounting assembly 100 of fig. 1. Specifically, the cradle head 200 can slide along the left-right direction relative to the mounting base 110, the front end and the rear end of the cradle head 200 are respectively provided with a slide rail 210, and the slide rail 210 extends along the left-right direction. Correspondingly, the front end and the rear end of the mounting seat 110 are respectively provided with a first sliding chute 111, and the first sliding chute 111 extends along the left-right direction. The slide rail 210 is inserted from the right side of the first slide groove 111 so that the pan/tilt head 200 can slide in the left and right direction with respect to the mount 110.

In order to stop the movement of the pan/tilt head 200 when the pan/tilt head 200 slides leftwards (i.e. in the first direction) to a position (i.e. in the fourth position) substantially coinciding with the upper and lower sides of the mounting base 110, a third stopper 112 (refer to fig. 3) is disposed on a surface of the mounting base 110 facing the pan/tilt head 200, the third stopper 112 is located at the left end of the mounting base 110, and the third stopper 112 protrudes towards the pan/tilt head 200. One side of the cradle head 200 facing the mounting base 110 is provided with a second card slot 230, the second card slot 230 is located at the left end of the cradle head 200, and the second card slot 230 is a groove.

When the cradle head 200 slides to a position substantially coinciding with the upper and lower positions of the mounting seat 110, the third stopper 112 is inserted into the second slot 230 and abuts against the right side wall of the second slot 230, and the third stopper 112 gives a rightward acting force to the cradle head 200. Thus, when the pan/tilt head 200 reaches the fourth position (i.e., the position where the pan/tilt head 200 and the mounting base 110 substantially coincide vertically) under the action of the third block 112 and the second slot 230, the pan/tilt head does not continue to move relative to the mounting base 110 in the first direction (i.e., the leftward direction).

Referring to fig. 3 to 5, fig. 4 is an oblique view of the driving mechanism 120 and the chucking assembly 130 of fig. 1. In order to enable the cradle head 200 to be clamped and fixed on the mounting base 110 when the cradle head 200 reaches the fourth position, so as to realize the installation of the cradle head 200 on the mounting base 110, the driving mechanism 120 and the clamping assembly 130 are provided. The clamping assembly 130 includes a first link 131, a clamping block 132, a first torsion spring 133, a second mounting bracket 134, a second pin 135, a rotating shaft, a second screw 137, a fourth pin 138, a trigger 139, a first elastic member, and a third mounting bracket 142. The clamping block 132 is rotatably connected to the mounting base 110, the clamping block 132 is provided with a first stopper 151 (see fig. 3 and 5), and the mounting base 110 is provided with a first hole (see fig. 3). When the clamping block 132 rotates counterclockwise relative to the mounting base 110 (see fig. 5, viewed from the front to the back), the first stopper 151 can pass through the first hole to the outside of the mounting base 110, thereby approaching the pan/tilt head 200. When the clamping block 132 rotates clockwise relative to the mounting base 110 (see fig. 5, viewed from the front to the back), the first stopper 151 can be retracted into the mounting base 110 from the first hole, that is, the first stopper 151 can be away from the pan/tilt head 200.

The trigger block 139 is slidably connected to the mounting base 110, and the trigger block 139 is slidable in the left-right direction relative to the mounting base 110. A second stopper 152 (see fig. 3 and 4) is disposed on a lower surface of the contact block 139, a second hole (see fig. 3) is disposed in the mounting base 110, the second stopper 152 is disposed in the second hole, and the second stopper 152 can slide in the second hole in the left-right direction. The right end of the first link 131 is rotatably connected to the clamping block 132, and the left end of the first link 131 is rotatably connected to the trigger block 139. Thus, by driving the clamping block 132 to rotate relative to the mounting base 110, the contact block 139 can be driven by the first connecting rod 131 to slide in the left-right direction relative to the mounting base 110.

Specifically, the clamping block 132 includes a first arm and a second arm, an included angle between the first arm and the second arm is an acute angle, and the first arm and the second arm are integrally disposed. The intersection of first arm and second arm is provided with the second through-hole, and the second through-hole is located the right downside of chucking piece 132. The second mounting frame 134 is locked and fixed on the mounting base 110 by a third screw, the second mounting frame 134 is provided with two third through holes, the axes of the two third through holes are positioned on the same straight line and arranged along the front-back direction, and the two third through holes are arranged at intervals in the front-back direction. The second pin 135 passes through the third through hole and the second through hole in the front side and the third through hole in the rear side in sequence, and then is clamped and fixed with the clamp spring. Thus, the chucking block 132 can rotate relative to the mount base 110, and the rotation axis is set in the front-rear direction.

In another embodiment, the second pin 135 and the clamp spring may be replaced by a screw and a nut, so as to realize the rotational connection of the clamping block 132 and the mounting seat 110.

The first stopper 151 is disposed on a lower surface of the first arm, and a right end of the first link 131 is rotatably connected to the second arm. The right end of the first link 131 is provided with a waist-shaped hole 154 (see fig. 4), the longitudinal direction of the waist-shaped hole 154 is substantially in the left-right direction, two waist-shaped holes 154 are provided, and the two waist-shaped holes 154 are provided at an interval. The upper end of the second arm is provided with a first through hole, and after the rotating shaft passes through the kidney-shaped hole 154 and the first through hole, the right end of the first connecting rod 131 is rotatably connected with the clamping block 132.

In this embodiment, the rotating shaft is a third pin 136, and the third pin 136 passes through the kidney-shaped hole 154 and the first through hole and then is clamped with the clamp spring.

In another embodiment, the shaft may also be provided with a screw that is threaded through the kidney-shaped hole 154 and the first through hole and then engages with the nut.

In another embodiment, a waist-shaped hole 154 may be provided at the left end of the first link 131, and the trigger block 139 is rotatably connected to the left end of the first link 131 through the waist-shaped hole 154.

The touch block 139 is slidably connected to the mounting base 110. Specifically, the front end and the rear end of the touch block 139 are respectively provided with a sliding edge 153 (refer to fig. 4), the front end and the rear end of the third mounting frame 142 are respectively provided with a second sliding groove 157 (refer to fig. 5), the two second sliding grooves 157 are both arranged on the inner wall of the cavity at the lower side of the third mounting frame 142, and the two second sliding grooves 157 are arranged oppositely. After the sliding edge 153 is placed in the second sliding groove 157, the third mounting frame 142 is locked on the mounting base 110 by the fourth screw, so that the touch block 139 can slide in the left-right direction relative to the mounting base 110.

In another embodiment, a guide hole may be provided on the trigger 139, a guide shaft may be provided on the third mounting bracket 142, and after the guide shaft is inserted into the guide hole, the third mounting bracket 142 may be locked to the mounting base 110 by a fourth screw, thereby achieving the sliding connection between the trigger 139 and the mounting base 110.

The right end of the touch block 139 is provided with a fourth through hole, the left end of the first connecting rod 131 is provided with two fifth through holes, the axes of the two fifth through holes are located on the same straight line, and the two fifth through holes are arranged at intervals. And the fourth pin 138 is clamped with the clamp spring after passing through the fourth through hole and the fifth through hole. Thus, the trigger 139 is rotatably connected to the left end of the first link 131.

In the process that the clamping block 132 rotates clockwise relative to the mounting base 110 (see fig. 5, viewed from front to back), the touch block 139 slides rightward relative to the mounting base 110, when the clamping block 132 rotates to the first position, the right end of the touch block 139 is located below the left end of the first arm of the clamping block 132, the right end of the touch block 139 abuts against the first arm of the clamping block 132, and the clamping block 132 cannot rotate counterclockwise relative to the mounting base 110 (see fig. 5, viewed from front to back). At this time, the first stopper 151 has retracted from the first hole into the mounting seat 110, and since the trigger block 139 prevents the clamping block 132 from rotating in the counterclockwise direction (as viewed from the front to the back with reference to fig. 5), the first stopper 151 cannot slide out of the mounting seat 110 from the first hole until the trigger block 139 slides to the left with respect to the mounting seat 110.

By the external force acting on the second stopper 152, the trigger 139 slides to the left relative to the mounting base 110, and after the trigger 139 slides to the left for a certain distance, the right end of the trigger 139 is disengaged from the left end of the first arm of the clamping block 132. In the process that the touch block 139 slides leftwards, the touch block 139 can drive the first connecting rod 131 to move, because the right end of the first connecting rod 131 is provided with the waist-shaped hole 154, the third pin 136 can move leftwards and rightwards in the waist-shaped hole 154, in the process, the right end of the first connecting rod 131 cannot drive the clamping block 132, the clamping block 132 cannot rotate anticlockwise (refer to fig. 5, viewed from the front to the back), the left end of the first arm of the clamping block 132 cannot clamp the right end of the touch block 139, and the touch block 139 can slide leftwards. The third pin 136 still slides to the left in the kidney-shaped hole 154 until the right end of the trigger 139 is disengaged from the left end of the first arm of the clamping block 132. When the third pin 136 slides to abut against the left inner wall of the kidney-shaped hole 154, the right end of the trigger 139 is already disengaged from the left end of the first arm of the clamping block 132.

In order to prevent the contact block 139 from accidentally sliding leftward, the right end of the contact block 139 is separated from the left end of the first arm of the clamping block 132, and the first stopper 151 extends out of the mounting base 110 from the first hole, and a first elastic element is disposed. The first elastic member gives the trigger block 139 a rightward force so that the trigger block 139 approaches the chuck block 132. When the right end of the trigger block 139 is located below the left end of the first arm of the clamping block 132, the trigger block 139 will not slide leftward without any trouble, the right end of the trigger block 139 can continuously maintain the abutting state with the left end of the first arm of the clamping block 132, and the first stopper 151 will not extend out of the mounting base 110 from the first hole accidentally.

In this embodiment, the first elastic element is a compression spring 141, the trigger block 139 is provided with a containing hole along the left-right direction, the containing hole is a blind hole, and the left end of the containing hole is open. Before the sliding edge 153 is placed in the second sliding groove 157, the compression spring 141 is placed in the accommodating hole. After the third mounting bracket 142 is locked and fixed on the mounting base 110, the left end of the compression spring 141 abuts against the third mounting bracket 142, and the right end of the compression spring 141 abuts against the touch block 139, so that a right acting force is applied to the touch block 139. When the touch block 139 needs to move to the left, the second stopper 152 overcomes the elastic force of the compression spring 141 to do work.

In another embodiment, the first elastic element may also be selected from a bellows or a rubber column, and the installation method of the bellows or the rubber column is the same as that of the compression spring 141.

In order to enable the clamping block 132 to rotate counterclockwise automatically (as viewed from the front to the back with reference to fig. 5), when the right end of the trigger 139 is disengaged from the left end of the first arm of the clamping block 132, the first stopper 151 may automatically extend out of the mounting base 110 from the first hole, and a first torsion spring 133 is disposed. The first torsion spring 133 includes a first swing arm and a second swing arm, which are respectively formed by extending spring lines to both sides. The first torsion spring 133 is sleeved on the second pin 135, the first swing arm abuts against the second arm of the clamping block 132, and the second swing arm abuts against the second mounting frame 134. In the initial state, the first torsion spring 133 is in the winding state, so that the chucking block 132 has a tendency to rotate in the counterclockwise direction (see fig. 5, viewed from the front to the rear).

Referring to fig. 3 to 5, in order to drive the chucking block 132 to rotate in a clockwise direction (see fig. 5, viewed from the front to the rear), a driving mechanism 120 is provided. The driving mechanism 120 includes a handle 121, a first mounting bracket 122, a second torsion spring 123, an eccentric link 124, a first pin 125, a second link 126, a conversion joint 127, and a first screw 128. The first mounting bracket 122 is locked and fixed on the mounting base 110 by a screw, the left end of the eccentric connecting rod 124 is rotatably connected with the third mounting bracket 142, and the right end of the eccentric connecting rod 124 is rotatably connected with the first mounting bracket 122. The left end of the eccentric connecting rod 124 is provided with a cylindrical shaft, the third mounting frame 142 is provided with a cylindrical hole, and the cylindrical shaft is arranged in the cylindrical hole in a penetrating mode, so that the left end of the eccentric connecting rod 124 is connected with the third mounting frame 142 in a rotating mode. The structure of the right end of the eccentric link 124 rotatably coupled to the first mounting bracket 122 is similar to the structure of the left end of the eccentric link 124 rotatably coupled to the third mounting bracket 142, and will not be described again.

The handle 121 is sleeved on the right end of the eccentric connecting rod 124 and then locked by a screw. Thus, by pulling the handle 121, the eccentric link 124 can be driven to rotate. The left end of the eccentric link 124 is rotatably connected to the upper end of the second link 126, the lower end of the second link 126 is rotatably connected to the switching joint 127, and the switching joint 127 is rotatably connected to the second arm of the clamping block 132.

The rotational connection between the left end of the eccentric link 124 and the upper end of the second link 126 is achieved by a first pin 125, and the first pin 125 is installed in the same manner as the second pin 135, and will not be described again. The lower end of the second connecting rod 126 is rotatably connected with the conversion joint 127 through a first screw 128, the conversion joint 127 is rotatably connected with the second arm of the clamping block 132 through a second screw 137, the first screw 128 or the second screw 137 is installed in the same manner as the second pin 135, except that the first screw 128 or the second screw 137 is in threaded fit with a nut, and the second pin 135 is clamped with a clamping spring.

The rotation axes of the eccentric connecting rod 124 and the mounting base 110 are a first axis, the rotation axes of the upper end of the second connecting rod 126 and the eccentric connecting rod 124 are a second axis, and the first axis and the second axis are not collinear, so that the second connecting rod 126 can be driven to move in the vertical direction when the eccentric connecting rod 124 rotates relative to the mounting base 110.

Because the second connecting rod 126 swings around the axis in the left-right direction and the clamping block 132 swings around the axis in the front-rear direction, if the lower end of the second connecting rod 126 is directly connected with the clamping block 132 in a rotating manner, the second connecting rod 126 and the clamping block 132 are clamped, and the second connecting rod 126 cannot drive the clamping block 132 to swing around the axis in the front-rear direction. Therefore, the second link 126 of the present embodiment is connected to the clamping block 132 by changing the pitch of the joint 127. The rotation axes of the conversion joint 127 and the lower end of the second connecting rod 126 are a third axis, the rotation axes of the conversion joint 127 and the clamping block 132 are a fourth axis, and the third axis is perpendicular to the fourth axis.

Thus, when the eccentric link 124 swings about the axis in the left-right direction, the chucking block 132 can be driven to swing about the axis in the front-rear direction.

In order to assist the first torsion spring 133 and automatically extend the first stopper 151 out of the mounting seat 110 from the first hole, a second torsion spring 123 is provided. The second torsion spring 123 is sleeved at the right end of the eccentric connecting rod 124, the third swing arm of the second torsion spring 123 abuts against the first mounting frame 122, and the fourth swing arm of the second torsion spring 123 abuts against the eccentric connecting rod 124. In the initial state, the second torsion spring 123 is in the wound-up state, and thus the eccentric link 124 tends to rotate in the counterclockwise direction (as viewed from right to left with reference to fig. 5).

Referring to fig. 4, in order to limit the limit position of the eccentric link 124 in the counterclockwise direction (see fig. 5, when viewed from the right to the left), and thus limit the extent to which the first stopper 151 protrudes from the first hole, a first positioning block 155 is provided on the eccentric link 124, and a second positioning block 156 is provided on the first mounting bracket 122. When the eccentric link 124 rotates counterclockwise to a predetermined position (as viewed from right to left in fig. 5), the first positioning block 155 abuts against the second positioning block 156, and the eccentric link 124 cannot rotate counterclockwise (as viewed from right to left in fig. 5).

Referring to fig. 3, in order to make the structure more compact and the appearance more beautiful, the left half of the first hole is separated on the third stopper 112, and the right half of the first hole is separated outside the third stopper 112. Therefore, when the holder 200 slides to the third position leftwards relative to the mounting base 110, the inner wall of the second engaging groove 230 first abuts against the second stopper 152. During the process that the cradle head 200 continues to slide leftward relative to the mounting base 110, the cradle head 200 carries the second stopper 152 (i.e., the contact block 139) to slide leftward. When the holder 200 slides leftwards to the fourth position relative to the mounting base 110, the second stopper 152 and the third stopper 112 both abut against the inner wall of the second slot 230.

In summary, with reference to fig. 1 to 5, the mounting process of the head 200 to the mount base 110 and the process of detaching the head 200 from the mount base 110 will be described. Initially, the handle is rotated clockwise (as viewed from right to left with reference to fig. 5), and in the process, the clamping block 132 is rotated clockwise (as viewed from front to back with reference to fig. 5), the clamping block 132 drives the trigger 139 to slide rightward through the first connecting rod 131, the compression spring 141 assists to push the trigger 139 to move rightward, the first torsion spring 133 is compressed and wound, and the elastic potential energy of the first torsion spring 133 is gradually increased. When the clamping block 132 rotates clockwise to the first position (see fig. 5, viewed from the front to the back), the right end of the trigger 139 is located below the first arm of the clamping block 132, the right end of the trigger 139 abuts against the first arm of the clamping block 132, and the first stopper 151 retracts into the mounting seat 110 from the first hole.

When the cradle head 200 is installed, the slide rail 210 of the cradle head 200 slides in from the right end of the first slide groove 111 of the mounting base 110, and the cradle head 200 slides leftwards relative to the mounting base 110. Since the first stopper 151 has been retracted into the mount 110, the first stopper 151 does not affect the leftward sliding of the pan/tilt head 200 with respect to the mount 110, and there is no need to keep the first stopper 151 in a retracted state in the mount 110 by holding the handle 121.

The cradle head 200 slides leftwards relative to the mounting base 110 until the second stopper 152 is inserted into the second slot 230 at the left end of the cradle head 200, the inner wall of the second slot 230 abuts against the second stopper 152, and at this time, the cradle head 200 is located at the third position. The cradle head 200 continuously slides leftwards relative to the mounting base 110, and the cradle head 200 drives the contact block 139 to slide leftwards through the abutting between the inner wall of the second slot 230 and the second stopper 152. In this process, the right end of the trigger 139 is disengaged from the first arm of the clamping block 132, and after the right end of the trigger 139 is disengaged from the first arm of the clamping block 132, the clamping block 132 rotates counterclockwise (see fig. 5, viewed from the front to the back) under the action of the first torsion spring 133, and the first stopper 151 begins to extend out of the first hole.

When the holder 200 slides to the fourth position to the left, the second stopper 152 and the third stopper 112 both abut against the inner wall of the second slot 230, and the first stopper 151 extends out of the first hole and is inserted into the first slot 220. The head 200 is clamped by the third block 112 and the first block 151, thereby completing the mounting of the head 200 on the mounting base 110.

When the cloud platform 200 is installed, the handle 121 is located in a vertically downward state, and at this moment, the handle 121 also has the function of preventing the cloud platform 200 from sliding rightwards, so that the cloud platform 200 is prevented from accidentally breaking away from the installation seat 110, and the secondary protection function is realized.

When the holder 200 needs to be disassembled, the handle 121 is rotated clockwise (see fig. 5, viewed from the right to the front), the eccentric link 124 drives the clamping block 132 to rotate clockwise (see fig. 5, viewed from the front to the back) through the second link 126 and the switching joint 127, and the first stopper 151 begins to retract from the first hole into the mounting seat 110. After the first stopper 151 is completely retracted into the mounting seat 110, the cradle head 200 can be manually pushed out to the right. It should be noted that during the process of retracting the first stopper 151 into the mounting seat 110, the clamping block 132 will bring the moving block 139 to the right, i.e. the second stopper 152 can push the holder 200 to move to the right.

This embodiment still relates to an unmanned aerial vehicle, and this unmanned aerial vehicle includes foretell quick detach device, still includes the unmanned aerial vehicle body. Quick detach device's mount pad 110 locking is fixed on the unmanned aerial vehicle body, and the load is then fixed on cloud platform 200, installs fast on mount pad 110 through cloud platform 200 to realize the quick installation of load.
