Referring to fig. 1 to 3, fig. 1 is an oblique view of a quick release device of a first embodiment, fig. 2 is an oblique view of the quick release device of fig. 1 at another angle, and fig. 3 is an oblique view of a mounting assembly of fig. 1. The quick release device of the present embodiment includes a pan and tilt head assembly 100 and a mounting assembly 200. The holder assembly 100 includes a holder 110 and a circuit board, the circuit board is locked and fixed on the holder 110, and a contact is disposed on the circuit board. The mounting assembly 200 comprises a mounting seat 210, a clamping mechanism and a spring needle seat 320, wherein the spring needle seat 320 is locked and fixed on the mounting seat 210, and a plurality of spring needles 321 arranged in an array are arranged on the spring needle seat 320. The cradle head 110 is slidably connected to the mounting base 210 and is clamped by a clamping mechanism. After the holder 110 is tightly clamped with the mounting base 210, the elastic pin 321 contacts with a contact of the circuit board, and the elastic pin 321 is electrically connected with the circuit board.

In order to realize the sliding connection between the cradle head 110 and the mounting base 210, two sliding grooves 211 (refer to fig. 2) are respectively disposed on two sides of the mounting base 210, two sliding rails 117 (refer to fig. 2) are respectively disposed on two sides of the cradle head 110, and the sliding rails 117 are inserted into the sliding grooves 211 and can slide along the sliding grooves 211. Thereby, the pan/tilt head 110 can slide in the front-rear direction with respect to the mount 210 (see fig. 1).

In order to prevent the cradle head 110 from falling off from the mounting seat 210 when the cradle head 110 slides backward relative to the mounting seat 210, a protrusion 114 is disposed at the front end of the cradle head 110. Therefore, when the holder 110 slides backwards to a certain position, the protrusion 114 will abut against the front end of the mounting seat 210, and the holder 110 will not be separated from the mounting seat 210.

Referring to fig. 1, 4 to 6, fig. 4 is an oblique view of the chucking mechanism in fig. 1, fig. 5 is an oblique view of the chucking mechanism in fig. 1 from another angle, and fig. 6 is an exploded view of the chucking mechanism in fig. 1. In order to cooperate with the protrusion 114 to clamp the cradle head 110 on the mounting base 210, so as to fix the cradle head assembly 100, a clamping mechanism is provided. The clamping mechanism comprises a handle 220, a mounting frame 230, a torsion spring 240, an eccentric wheel 250, a first stop 260, a first connecting rod 270, a positioning frame 280, a second connecting rod 290 and a second stop 310, wherein the mounting frame 230 is locked and fixed on the mounting base 210, and the handle 220 is rotatably connected with the mounting frame 230. The eccentric wheel 250 includes a first shaft 251, a body 252, and a second shaft 253, and the first shaft 251, the body 252, and the second shaft 253 are integrally formed by injection molding. The first shaft 251 and the second shaft 253 are respectively positioned at two sides of the main body 252, the axial center of the first shaft 251 is not overlapped with the axial center of the second shaft 253, and the first shaft 251 is fixedly connected with the handle 220.

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

The rotating shaft 223 is provided with a second through hole 221 along the axial direction, the first shaft 251 is provided with a first threaded hole along the axial direction, the first shaft 251 is arranged in the second through hole 221 in a penetrating mode, meanwhile, a first screw penetrates through the second through hole 221 and is screwed into the first threaded hole, and therefore the first shaft 251 and the handle 220 are fixed together. In addition, the two sides of the mounting frame 230 are respectively abutted against the main body 252 and the limiting step 224 of the handle 220, and the rotating shaft 223 cannot be separated from the first through hole 232 in the process that the handle 220 rotates relative to the mounting frame 230.

In order to prevent the first shaft 251 from slipping, an arcuate protrusion is axially disposed on the inner wall of the second through hole 221, a notch with a corresponding shape is disposed on the circumferential surface of the first shaft 251, and after the first shaft 251 is inserted into the second through hole 221, the arcuate protrusion and the notch cooperate to form a structure similar to a key and a key slot, so as to prevent the first shaft 251 from slipping relative to the handle 220.

The middle position of the first connecting rod 270 is provided with a third through hole 272, the third through hole 272 is a round hole, the second screw is in clearance fit with the third through hole 272, and the second screw passes through the third through hole 272 and then is in threaded fit with the mounting bracket 230, so that the first connecting rod 270 can rotate relative to the mounting bracket 230. One end of the first link 270 is provided with a first connecting groove 271, the other end of the first link 270 is provided with a second connecting groove 273, the first connecting groove 271 and the second connecting groove 273 are both elongated "U" -shaped grooves, and the length direction of the first connecting groove 271 and the length direction of the second connecting groove 273 are both arranged along the length direction of the first link 270. The second shaft 253 is inserted into the first coupling groove 271. Therefore, after the handle 220 rotates, the movement track of the second shaft 253 is arc-shaped, and due to the long and narrow first connecting groove 271, the second shaft 253 drives the first connecting rod 270 to swing, and simultaneously the second shaft 253 slides along the first connecting groove 271, so that the second shaft 253 and the first connecting rod 270 cannot be clamped.

The first stopper 260 is movable in an up-and-down direction with respect to the mount 210. Specifically, the mounting base 210 is provided with a first guide hole along the up-down direction, the first stopper 260 is disposed in the first guide hole, and the first stopper 260 is in clearance fit with the first guide hole. Two hangers are arranged at the upper end of the first stop block 260 in parallel at intervals, one hanger is provided with a fourth through hole, and the other hanger is provided with a second threaded hole. After the first stopper 260 is disposed in the first guiding hole, the third screw sequentially passes through the fourth through hole and the second connecting groove 273, and finally is screwed into the second threaded hole. Therefore, when the first link 270 swings, the first link 270 may drive the first stopper 260 to move up and down relative to the mounting base 210, and in this process, the third screw may slide in the second connecting groove 273, and the third screw may not be locked with the first link 270.

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. When the first stopper 260 is extended from the mount 210, the handle 220 is located at the first position (referring to fig. 1, the handle 220 is located at the first position in fig. 1), and when the first stopper 260 is retracted into the mount 210, the handle 220 is located at the second position (referring to fig. 5, the handle 220 is located at the second position in fig. 5).

In another embodiment, the third through hole 272 may be a kidney-shaped hole, the second screw is inserted into the kidney-shaped hole, and a round hole is used instead of the first connecting groove 271, the second shaft 253 is inserted into the round hole, and the second shaft 253 is in clearance fit with the round hole. Therefore, the first link 270 can also rotate relative to the mounting bracket 230, and the handle 220 can also be rotated to extend the first stopper 260 out of the mounting seat 210 or retract the first stopper 260 into the mounting seat 210, and in the process, the second screw can slide in the kidney-shaped hole to prevent the second shaft 253 from being locked with the first link 270.

The structure of the second shaft 253 for driving the second stopper 310 to extend and retract through the second link 290 is the same as the structure of the second shaft 253 for driving the first stopper 260 to extend and retract through the first link 270, and a description thereof will not be repeated. It should be noted that the eccentric 250 allows the first stopper 260 and the second stopper 310 to simultaneously extend from the mounting seat 210, or allows the first stopper 260 and the second stopper 310 to simultaneously retract into the mounting seat 210.

To constrain the motion profile defining the second shaft 253, a spacer 280 is provided. Two ends of the positioning frame 280 are locked and fixed on the mounting frame 230 through second screws, an arc-shaped hole 281 is arranged in the middle of the positioning frame 280, and the second shaft 253 penetrates through the arc-shaped hole 281. Thus, the second shaft 253 can only move within the range agreed by the arcuate apertures 281.

The mount 210 is provided with a first observation window 212 (see fig. 3) for observing the extended/retracted state of the first stopper 260. The first observation window 212 is an observation hole communicating with the first guide hole, and the position of the first stopper 260 can be observed through the observation hole.

In this embodiment, in order to seal the observation hole, the observation hole is provided with an installation groove, and transparent glass or plastic blocks are bonded and fixed in the installation groove. This prevents moisture or the like from entering the mount 210 through the observation hole.

To clearly identify the state of the first stopper 260, the first stopper 260 is provided with a first painted area 262 (refer to fig. 4), and the first painted area 262 may be painted with green, and when the green is viewed through the first viewing window 212, the first stopper 260 is in a state of protruding from the mounting seat 210. Alternatively, the first painted area 262 may be painted red, and when the red is viewed through the first viewing window 212, it means that the first stopper 260 is in a state of being retracted into the mounting seat 210.

Correspondingly, a second observation window is further arranged on the mounting base 210, a second color-coated area is arranged on the second stopper 310, and the second color-coated area can be observed through the second observation window, so that the telescopic state of the second stopper 310 is determined. The second viewing window has the same structure as the first viewing window 212.

In order to maintain the state in which the first stopper 260 and the second stopper 310 are protruded from the mount 210, a torsion spring 240 is provided. The torsion spring 240 is sleeved on the positioning step 222, the inner wall of the first through hole 232 is provided with a limiting groove 231, the first swing arm of the torsion spring 240 is arranged in the limiting groove 231 in a penetrating manner, and the second swing arm of the torsion spring 240 is arranged in the main body 252 in a penetrating manner. When the handle 220 is in the first position (referring to fig. 1, the handle 220 is in the first position in fig. 1), the torsion spring 240 is in a natural state. When the handle 220 is rotated clockwise by 90 ° by an external force (see fig. 1, when viewed from the front to the rear), the handle 220 is in the second position (see fig. 5, the handle 220 in fig. 5 is in the second position). At this time, the torsion spring 240 is deformed by the force, and the torsion spring 240 gives the handle 220 a force in the counterclockwise direction. After the handle 220 loses its external force, the torsion spring 240 will swing the handle 220 from the second position to the first position.

The left side of the cradle head 110 is provided with a first card slot 113, and the right side of the cradle head 110 is provided with a second card slot 115. The cradle head 110 slides along a first direction (referring to fig. 1, the first direction is a backward direction) relative to the mounting base 210 until the protrusion 114 abuts against the front end of the mounting base 210. At this time, the first stopper 260 and the second stopper 310 are extended from the mounting base 210, the first stopper 260 is inserted into the first card slot 113, the second stopper 310 is inserted into the second card slot 115, and both the first stopper 260 and the second stopper 310 can prevent the pan/tilt head 110 from sliding relative to the mounting base 210 in a second direction opposite to the first direction (referring to fig. 1, the second direction is a forward direction). Therefore, under the matching of the first stop block 260, the second stop block 310 and the protrusion 114, the holder assembly 100 is clamped on the mounting seat 210, the holder assembly 100 cannot fall off, and one-time protection of the holder assembly 100 is realized.

Further, by providing a torsion spring 240, the handle 220 may be maintained in the first position. At this time, the first stopper 260 and the second stopper 310 extend out from the mounting seat 210, and the first stopper 260 and the second stopper 310 keep the holder 110, thereby preventing the holder assembly 100 from falling off.

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 cradle head 110. At this time, the mounting base 210 may also prevent the pan/tilt head 110 from sliding along the first direction (referring to fig. 1, the first direction is a backward direction), so as to cooperate with the first stopper 260 and the second stopper 310 to clamp the pan/tilt head assembly 100 on the mounting base 210.

When the first stopper 260 protrudes from the mounting seat 210, the handle 220 is located at the first position (see fig. 1), and the holding portion of the handle 220 extends downward (see fig. 1). If the cradle head 110 slides along the first direction (referring to fig. 1, the first direction is a backward direction) relative to the mounting base 210, the holding portion of the handle 220 will abut against the protrusion 114, and the handle 220 can also play a role in preventing the cradle head assembly 100 from falling off, thereby performing a secondary protection on the cradle head assembly 100.

In another embodiment, only the first link 270 and the first stopper 260 may be provided without the second link 290 and the second stopper 310. At this time, the first stopper 260 still can play a role of chucking the cradle head 110, and the structure is simpler and the cost is lower. By providing the first stop 260 and the second stop 310, the clamping state of the holder 110 is more stable.

Referring to fig. 1, in the process that the pan/tilt head 110 slides backward relative to the mounting base 210, that is, in the process that the pan/tilt head 110 is mounted on the mounting base 210, the handle 220 does not abut against the protrusion 114, the handle 220 does not interfere with the mounting, the left side of the upper surface of the pan/tilt head 110 is provided with the first avoiding groove 111, the right side of the upper surface of the pan/tilt head 110 is provided with the second avoiding groove 116, and the first avoiding groove 111 and the second avoiding groove 116 are both arranged along the front-back direction.

The rear end of the first avoiding groove 111 is provided with a first inlet, and in the process that the holder 110 slides backward relative to the mounting base 210 (at this time, the first stopper 260 is in a state of extending out of the mounting base 210), the first stopper 260 enters the first avoiding groove 111 from the first inlet and slides along the first avoiding groove 111. Since the first escape groove 111 has a certain depth, the first stopper 260 is not retracted into the mount 210. The front end of the first avoiding groove 111 is provided with a first guiding surface 112, the rear side of the first guiding surface 112 is connected with the bottom surface of the first avoiding groove 111, and the front side of the first guiding surface 112 is connected with the upper surface of the holder 110. Thus, when the handle 220 approaches the protrusion 114, the first stopper 260 abuts against the first guide surface 112, and the first stopper 260 is gradually pushed 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 link 270 and the cam 250, and the handle 220 does not abut against the protrusion 114 during the process of the backward sliding of the holder 110 relative to the mounting base 210.

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 seat 210 and is clamped into the first slot 113, thereby completing the locking of the holder assembly 100.

The shape of the second avoiding groove 116 is the same as the shape of the first avoiding groove 111, the second avoiding groove 116 is used for avoiding the second stopper 310, and the second stopper 310 also slides along the second avoiding groove 116 simultaneously when the first stopper 260 slides along the first avoiding groove 111.

In other embodiments, the torsion spring 240 may be replaced with a compression spring. At this time, 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, the compression spring is disposed 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. In the process of the compression spring returning to 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.

In this embodiment, the first guide surface is a slope. In a further embodiment, the first guide surface is a cambered surface.

Referring to fig. 5, in order to facilitate the first stopper 260 to slide smoothly on the first guide surface 112, a first stopper point 261 at which the first stopper 260 protrudes into the first catching groove 113 is provided with a slope surface, which is disposed toward the first guide surface. Accordingly, when the first stopper 260 slides along the first guide surface 112, the contact area is larger, and the contact type is surface contact, and the sliding friction force of the surface contact is smaller than that of point contact or line contact.
