[0026] Reference Figures 1 to 3 , Figure 1 is an oblique view of the quick release device of the first embodiment, Figure 2 yes Figure 1 An oblique view of the quick release device from another angle. Figure 3 yes Figure 1 The oblique view of the installation assembly in the figure. The quick release device of this embodiment includes a pan-tilt assembly 100 and a mounting assembly 200. The pan-tilt assembly 100 includes a pan-tilt 110 and a circuit board, the circuit board is locked and fixed on the pan-tilt 110, and contacts are provided on the circuit board. The installation assembly 200 includes a mounting seat 210, a clamping mechanism and a spring pin seat 320, the spring pin seat 320 is locked and fixed on the mounting seat 210, and a plurality of spring pins 321 arranged in an array are provided on the spring pin seat 320. The pan-tilt 110 is slidably connected to the mounting seat 210 and is clamped by a clamping mechanism. After the pan-tilt 110 is clamped to the mounting seat 210, the spring pin 321 contacts with the contacts of the circuit board, and the spring pin 321 is electrically connected to the circuit board.

[0027] In order to realize the sliding connection between the pan head 110 and the mounting base 210, a slide groove 211 is provided on both sides of the mounting base 210 (refer to Figure 2 ), a slide rail 117 is provided on both sides of the pan / tilt platform 110 (refer to Figure 2), the slide rail 117 is inserted into the slide groove 211 and can slide along the slide groove 211. As a result, the pan head 110 can slide in the front-rear direction relative to the mounting seat 210 (refer to Figure 1 ).

[0028] In order to prevent the platform 110 from falling off the mounting seat 210 when the platform 110 slides backward relative to the mounting seat 210, a protrusion 114 is provided at the front end of the platform 110. Therefore, when the platform 110 slides backward to a certain position, the protrusion 114 will abut against the front end of the mounting seat 210, and the platform 110 will not fall off the mounting seat 210.

[0029] Reference Figure 1 , Figures 4 to 6 , Figure 4 yes Figure 1 Oblique view of the clamping mechanism in the middle, Figure 5 yes Figure 1 The oblique view of the clamping mechanism from another angle. Figure 6 yes Figure 1 Exploded diagram of the clamping mechanism. In order to clamp the pan-tilt head 110 on the mounting seat 210 with the protrusion 114, and realize the installation and fixation of the pan-tilt head assembly 100, a clamping mechanism is provided. The clamping mechanism includes a handle 220, a mounting frame 230, a torsion spring 240, an eccentric wheel 250, a first stopper 260, a first connecting rod 270, a positioning frame 280, a second connecting rod 290 and a second stopper 310. The mounting frame 230 is locked and fixed on the mounting seat 210, and the handle 220 is rotatably connected to the mounting frame 230. The eccentric wheel 250 includes a first shaft 251, a main body 252 and a second shaft 253. The first shaft 251, the main body 252 and the second shaft 253 are integrally arranged and can be formed by injection molding. The first shaft 251 and the second shaft 253 are respectively located on both sides of the main body 252, and the axis of the first shaft 251 does not coincide with the axis of the second shaft 253. The first shaft 251 is fixedly connected to the handle 220.

[0030] The mounting frame 230 is provided with a first through hole 232 , and the handle 220 is provided with a rotating shaft 223 . The rotating shaft 223 passes through the first through hole 232 , so that the handle 220 can rotate relative to the mounting frame 230 .

[0031] The rotating shaft 223 is provided with a second through hole 221 along the axial direction, and the first shaft 251 is provided with a first threaded hole along the axial direction. The first shaft 251 is inserted into the second through hole 221. At the same time, the first screw passes through the second through hole 221 and is screwed into the first threaded hole, thereby fixing the first shaft 251 and the handle 220 together. In addition, the two sides of the mounting frame 230 are distributed to abut against the limiting steps 224 of the main body 252 and the handle 220. When the handle 220 rotates relative to the mounting frame 230, the rotating shaft 223 will not be separated from the first through hole 232.

[0032] To prevent the first shaft 251 from slipping, an arched protrusion is axially arranged on the inner wall of the second through hole 221, and a notch of a corresponding shape is arranged on the circumferential surface of the first shaft 251. After the first shaft 251 is inserted into the second through hole 221, the arched protrusion cooperates with the notch to form a structure similar to that of a key and a keyway, thereby preventing the first shaft 251 from slipping relative to the handle 220.

[0033] A third through hole 272 is provided at the middle of the first connecting rod 270. The third through hole 272 is a round hole. The second screw is in clearance with the third through hole 272. After the second screw passes through the third through hole 272, it is threadedly engaged with the mounting bracket 230, so that the first connecting rod 270 can rotate relative to the mounting bracket 230. A first connecting groove 271 is provided at one end of the first connecting rod 270, and a second connecting groove 273 is provided at the other end of the first connecting rod 270. Both the first connecting groove 271 and the second connecting groove 273 are narrow and long "U"-shaped grooves, and the length direction of the first connecting groove 271 and the length direction of the second connecting groove 273 are arranged along the length direction of the first connecting rod 270. The second shaft 253 is inserted into the first connecting groove 271. Therefore, after the handle 220 is rotated, the movement trajectory of the second shaft 253 is arc-shaped. Due to the provision of the narrow and long first connecting groove 271, while the second shaft 253 drives the first connecting rod 270 to swing, the second shaft 253 itself will also slide along the first connecting groove 271, and the second shaft 253 and the first connecting rod 270 will not get stuck.

[0034] The first stopper 260 can move in the up-down direction relative to the mounting seat 210. Specifically, the mounting seat 210 is provided with a first guide hole in the up-down direction, the first stopper 260 is placed in the first guide hole, and the first stopper 260 is matched with the first guide hole in a clearance. Two hanging ears are arranged in parallel and spaced apart at the upper end of the first stopper 260, one hanging ear is provided with a fourth through hole, and the other hanging ear is provided with a second threaded hole. After the first stopper 260 is placed in the first guide hole, the third screw passes through the fourth through hole and the second connecting groove 273 in sequence, and finally screws into the second threaded hole. Thus, when the first connecting rod 270 swings, the first connecting rod 270 can drive the first stopper 260 to move in the up-down direction relative to the mounting seat 210, and in this process, the third screw will slide in the second connecting groove 273, and the third screw will not be stuck with the first connecting rod 270.

[0035] Thus, by rotating the handle 220, the first stopper 260 can be extended from the mounting seat 210, or the first stopper 260 can be retracted into the mounting seat 210. In addition, when the first stopper 260 is extended from the mounting seat 210, the handle 220 is located at the first position (refer to Figure 1 , Figure 1 The handle 220 is in the first position), and when the first stopper 260 is retracted into the mounting seat 210, the handle 220 is in the second position (refer to Figure 5 , Figure 5 The handle 220 is in the second position).

[0036] In another embodiment, the third through hole 272 can also be set as a waist-shaped hole, the second screw is inserted into the waist-shaped hole, and the first connecting groove 271 is replaced by a round hole, the second shaft 253 is inserted into the round hole, and the second shaft 253 is in clearance with the round hole. Thus, the first connecting rod 270 can also rotate relative to the mounting frame 230, and the handle 220 can be turned to extend the first stopper 260 from the mounting seat 210, or retract the first stopper 260 into the mounting seat 210. In this process, the second screw can slide in the waist-shaped hole to prevent the second shaft 253 and the first connecting rod 270 from getting stuck.

[0037] The structure in which the second shaft 253 drives the second stopper 310 to extend and retract through the second connecting rod 290 is the same as the structure in which the second shaft 253 drives the first stopper 260 to extend and retract through the first connecting rod 270, and the description thereof will not be repeated here. It should be noted that the eccentric wheel 250 causes the first stopper 260 and the second stopper 310 to extend and retract from the mounting seat 210 at the same time, or causes the first stopper 260 and the second stopper 310 to retract and retract into the mounting seat 210 at the same time.

[0038] In order to restrict the movement trajectory of the second shaft 253, a positioning frame 280 is provided. The two ends of the positioning frame 280 are fixed to the mounting frame 230 by second screws, and an arc hole 281 is provided in the middle of the positioning frame 280, and the second shaft 253 is inserted into the arc hole 281. Therefore, the second shaft 253 can only move within the range specified by the arc hole 281.

[0039] In order to observe the telescopic state of the first stopper 260, a first observation window 212 is provided on the mounting seat 210 (see Figure 3 The first observation window 212 is an observation hole connected to the first guide hole, through which the position of the first stopper 260 can be observed.

[0040] In this embodiment, in order to seal the observation hole, a mounting groove is further provided outside the observation hole, in which a transparent glass or plastic block is bonded and fixed, thereby preventing water vapor from entering the mounting seat 210 through the observation hole.

[0041] In order to clearly identify the state of the first stopper 260, a first coloring area 262 is provided on the first stopper 260 (see Figure 4 ), the first coloring area 262 may be painted green, and when green is observed through the first observation window 212, it indicates that the first stopper 260 is in a state of extending from the mounting seat 210. Alternatively, the first coloring area 262 may be painted red, and when red is observed through the first observation window 212, it indicates that the first stopper 260 is in a state of retracting into the mounting seat 210.

[0042] Correspondingly, the mounting seat 210 is further provided with a second observation window, and the second stopper 310 is provided with a second coloring area, through which the second coloring area can be observed, thereby determining the telescopic state of the second stopper 310. The structure of the second observation window is the same as that of the first observation window 212.

[0043] In order to keep the first stopper 260 and the second stopper 310 extending from the mounting seat 210, a torsion spring 240 is provided. The torsion spring 240 is sleeved on the positioning step 222, and a limiting groove 231 is formed on the inner wall of the first through hole 232. The first swing arm of the torsion spring 240 is inserted into the limiting groove 231, and the second swing arm of the torsion spring 240 is inserted into the main body 252. When the handle 220 is in the first position (refer to Figure 1 , Figure 1 The handle 220 is in the first position, and the torsion spring 240 is in a natural state. The handle 220 is rotated 90° clockwise by an external force (refer to Figure 1 , viewed from the front to the back), the handle 220 is in the second position (refer to Figure 5 , Figure 5 The handle 220 is in the second position. At this time, the torsion spring 240 is deformed by force, and the torsion spring 240 applies a force in the counterclockwise direction to the handle 220. After the handle 220 loses the effect of the external force, the torsion spring 240 will swing the handle 220 from the second position to the first position.

[0044] The left side of the pan-tilt 110 is provided with a first slot 113, and the right side of the pan-tilt 110 is provided with a second slot 115. The pan-tilt 110 slides relative to the mounting seat 210 along a first direction (refer to Figure 1 , the first direction is the backward direction) until the protrusion 114 abuts against the front end of the mounting seat 210. At this time, the first stopper 260 and the second stopper 310 extend from the mounting seat 210, the first stopper 260 will be inserted into the first slot 113, and the second stopper 310 will be inserted into the second slot 115. The first stopper 260 and the second stopper 310 can both prevent the pan / tilt head 110 from sliding relative to the mounting seat 210 in the second direction, which is opposite to the first direction (refer to Figure 1 , the second direction is the forward direction). Thus, under the cooperation of the first stopper 260, the second stopper 310 and the protrusion 114, the pan-tilt assembly 100 is clamped on the mounting seat 210, and the pan-tilt assembly 100 will not fall off, thereby achieving primary protection of the pan-tilt assembly 100.

[0045] In addition, the handle 220 can be kept in the first position by providing the torsion spring 240. At this time, the first stopper 260 and the second stopper 310 extend from the mounting seat 210, and the first stopper 260 and the second stopper 310 will keep the pan / tilt head 110 clamped, preventing the pan / tilt head assembly 100 from falling off.

[0046] In another embodiment, the protrusion 114 may also be disposed at the rear end of the mounting base 210, and the protrusion 114 abuts against the rear end of the pan / tilt head 110. In this case, the mounting base 210 may also prevent the pan / tilt head 110 from sliding along the first direction (see Figure 1 , the first direction is the backward direction), thereby cooperating with the first stop block 260 and the second stop block 310 to clamp the pan / tilt assembly 100 on the mounting base 210.

[0047] When the first stopper 260 extends from the mounting seat 210, the handle 220 is located at the first position (refer to Figure 1 ), at this time, the gripping portion of the handle 220 extends downward (refer to Figure 1 If the pan / tilt platform 110 slides relative to the mounting base 210 along the first direction (refer to Figure 1 , the first direction is the backward direction), the gripping portion of the handle 220 will abut against the protrusion 114, and the handle 220 can also prevent the pan-tilt assembly 100 from falling off, providing secondary protection for the pan-tilt assembly 100.

[0048] In another embodiment, only the first connecting rod 270 and the first stopper 260 may be provided, without the second connecting rod 290 and the second stopper 310. In this case, the first stopper 260 can still play the role of clamping the pan / tilt platform 110, but the structure is simpler and the cost is lower. If the first stopper 260 and the second stopper 310 are provided at the same time, the clamping state of the pan / tilt platform 110 will be more stable.

[0049] Reference Figure 1 In order that the handle 220 will not abut against the protrusion 114 and the handle 220 will not hinder the installation when the gimbal 110 slides backward relative to the mounting seat 210, that is, when the gimbal 110 is installed on the mounting seat 210, a first avoidance groove 111 is provided on the left side of the upper surface of the gimbal 110, and a second avoidance groove 116 is provided on the right side of the upper surface of the gimbal 110, and the first avoidance groove 111 and the second avoidance groove 116 are both provided along the front-to-back direction.

[0050] The first avoidance groove 111 is provided with a first entrance at the rear end. When the pan / tilt head 110 slides backward relative to the mounting seat 210 (at this time, the first stopper 260 is in a state of extending from the mounting seat 210), the first stopper 260 enters the first avoidance groove 111 from the first entrance and slides along the first avoidance groove 111. Since the first avoidance groove 111 has a certain depth, the first stopper 260 will not retract into the mounting seat 210. The first avoidance groove 111 is provided with a first guide surface 112 at the front end. The rear side of the first guide surface 112 is connected to the bottom surface of the first avoidance groove 111, and the front side of the first guide surface 112 is connected to the upper surface of the pan / tilt head 110. Therefore, when the handle 220 is about to approach the protrusion 114, the first stopper 260 abuts against the first guide surface 112, and the first stopper 260 is gradually lifted up and retracted into the mounting seat 210. The first stopper 260 rotates the handle 220 from the first position to the second position through the first connecting rod 270 and the cam 250 . When the pan / tilt head 110 slides backward relative to the mounting base 210 , the handle 220 will not abut against the protrusion 114 .

[0051] When the first stopper 260 passes through the first slot 113 , the handle 220 rotates from the second position to the first position under the action of the torsion spring 240 , and the first stopper 260 extends from the mounting base 210 and is inserted into the first slot 113 , thereby completing the locking of the pan / tilt assembly 100 .

[0052] The shape of the second avoidance groove 116 is the same as that of the first avoidance groove 111 . The second avoidance groove 116 is used to avoid the second stopper 310 . When the first stopper 260 slides along the first avoidance groove 111 , the second stopper 310 also slides synchronously along the second avoidance groove 116 .

[0053] In another embodiment, the torsion spring 240 may be replaced by a compression spring. In this case, an arc-shaped blind hole may be opened on the positioning frame 280, the opening of the blind hole is aligned with the arc-shaped hole 281, and the compression spring is placed in the blind hole, one end of the compression spring abuts against the positioning frame 280, and the other end of the compression spring abuts against the second shaft 253. During the process of the compression spring restoring the deformation, a force is applied to the second shaft 253, the second shaft 253 slides along the arc-shaped hole 281, and the second shaft 253 drives the handle 220 to rotate from the second position to the first position.

[0054] In this embodiment, the first guide surface is an inclined surface. In another embodiment, the first guide surface is a curved surface.

[0055] Reference Figure 5In order to facilitate the smooth sliding of the first stopper 260 on the first guide surface 112, a slope is provided on the first clamping point 261 where the first stopper 260 extends into the first clamping groove 113, and the slope is arranged toward the first guide surface. Therefore, when the first stopper 260 slides along the first guide surface 112, the contact area is larger, and the contact type is surface contact. Compared with point contact and line contact, the sliding friction of surface contact will be smaller.

[0056] The present invention also relates to a drone, which includes the above-mentioned quick-release device and a drone body, the mounting seat 210 is locked and fixed on the drone body, and the load is fixed on the gimbal 110. By using the quick-release device, the load can be quickly disassembled and assembled, and at the same time, the load is fixed on the gimbal 110, which can be protected by secondary protection and is not easy to loosen.

[0057] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
