[0021] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] With the improvement of living standards, photography has become an important part of people's lives, and the requirements for the photography experience are also getting higher and higher. In order to pursue a higher and more exquisite still or motion photography and videography level, the requirements of photographers for the shooting auxiliary accessories used for shooting are also getting higher and higher.

[0023] In the related art, as Figure 1 shown, the shooting auxiliary accessory 1' includes a worm 20' and a worm wheel 30'. The worm 20' is used to connect the photographic equipment, and the worm wheel 30' is meshed with the worm 20'. By rotating the worm wheel 30', the disassembly between the worm 20' and the housing 10' is realized, so as to realize the disassembly of the photographic equipment. However, since the size of the worm wheel 30' is small, when the torque is large, the phenomenon of tooth slipping will occur, which is not convenient for users to operate.

[0024] Therefore, how to design a new type of shooting auxiliary accessory 1' to realize the quick installation and quick disassembly of the photographic equipment has become an urgent problem to be solved.

[0025] Please refer to Figures 2 - 3 shown. To solve the above technical problems, on the one hand, the present application proposes a quick-release device 1, which can realize the quick installation and quick disassembly of the photographic equipment, and the operation is convenient and fast.

[0026] The quick-release device 1 includes a support 10, a connecting piece 20, a clamping assembly 30 and an unlocking assembly 40. The connecting piece 20 is used to connect the photographic equipment; the clamping assembly 30 includes a plurality of clamping arms 31 connected to the support 10; the plurality of clamping arms 31 have a first state and a second state. In the first state, the plurality of clamping arms 31 clamp the connecting piece 20, and in the second state, the plurality of clamping arms 31 loosen the connecting piece 20; the unlocking assembly 40 is connected to the support 10, and the unlocking assembly 40 is configured to move along the preset direction OO' to drive the plurality of clamping arms 31 to move, so that the plurality of clamping arms 31 are switched between the first state and the second state.

[0027] The following combines Figures 2 - 9 to introduce the specific structure of the quick-release device 1 in detail.

[0028] As Figures 2 - 3 shown, the quick-release device 1 includes a support 10, a connecting member 20, a clamping assembly 30, and a unlocking assembly 40.

[0029] The support 10 serves as the bracket of the quick-release device 1. The specific structure of the support 10 is not limited here, and designers can make reasonable designs according to actual needs; for example, the support 10 can but is not limited to include a top seat and a bottom seat, the top seat is connected to one end face of the bottom seat, and the outer peripheral side surface of the top seat is spaced from the outer peripheral side surface of the bottom seat to form a stepped structure. The specific material of the support 10 is not limited here, and designers can make reasonable designs according to actual needs; for example, the support 10 can but is not limited to be made of non-metallic materials such as plastics; or for another example, the support 10 can also but is not limited to be made of metallic materials such as aluminum alloy and stainless steel.

[0030] The connecting member 20 serves as the connection structure of the quick-release device 1 for connecting with an external photographic device (not shown in the figure, such as a camera). The specific connection method between the connecting member 20 and the photographic device is not limited here, and designers can make reasonable designs according to actual needs; for example, the connecting member 20 can but is not limited to be detachably connected to the photographic device by at least one of the ways such as screwing, clamping, or plugging. It can be understood that, due to the different specific connection methods between the connecting member 20 and the photographic device, the specific forms of the connecting member 20 are also different; for example, when the connecting member 20 is connected to the photographic device by screwing, the connecting member 20 includes a stud, and the photographic device has a threaded hole threadedly connected to the stud.

[0031] The clamping assembly 30 serves as the fixing structure of the quick-release device 1 for clamping or loosening the connecting member 20 to achieve the installation and disassembly between the connecting member 20 and the support 10; the clamping assembly 30 includes a clamping arm 31.

[0032] The clamping arm 31 serves as the fixing part of the clamping assembly 30 for clamping or loosening the connecting member 20; the specific structure of the clamping arm 31 is not limited here, and designers can make reasonable designs according to actual needs; it should be noted that when the connecting member 20 includes a stud, the surface of the clamping arm 31 in contact with the stud has teeth adapted to the external thread of the stud.

[0033] The number of the clamping arms 31 is multiple (more than two); for example, the number of the clamping arms 31 can but is not limited to be two, three, four, five, six or more.

[0034] The clamping arm 31 is connected to the support 10; the specific connection method between the clamping arm 31 and the support 10 is not limited here, and the designer can make a reasonable design according to actual needs; for example, when the clamping arm 31 is slidably connected to the support 10, the clamping arm 31 can, but is not limited to, be connected to the support 10 by means of a slider and a chute; for another example, when the clamping arm 31 is rotatably connected to the support 10, the clamping arm 31 can, but is not limited to, be connected to the support 10 by means of a rotating shaft.

[0035] As Figures 4 - 7 shown, the plurality of clamping arms 31 have a first state and a second state. In the first state, the plurality of clamping arms 31 clamp the connecting member 20; at this time, the connecting member 20 is clamped by the plurality of clamping arms 31 and positioned on the support 10, so that the relative position between the connecting member 20 and the support 10 can be fixed. In the second state, the plurality of clamping arms 31 release the connecting member 20; at this time, the connecting member 20 is not clamped by the plurality of clamping arms 31 and positioned on the support 10, so that the relative position between the connecting member 20 and the support 10 can be changed.

[0036] The unlocking assembly 40, as the locking and unlocking structure of the quick-release device 1, is used to drive the plurality of clamping arms 31 to move, so that the plurality of clamping arms 31 can be switched between the above-mentioned first state and the above-mentioned second state; the specific structure of the unlocking assembly 40 will be introduced in detail below.

[0037] The unlocking assembly 40 is connected to the support 10. The unlocking assembly 40 is configured to move along a preset direction OO' to drive the plurality of clamping arms 31 to move, so that the plurality of clamping arms 31 are switched between a first state and a second state. For example, when the plurality of clamping arms 31 are slidably connected to the support 10, the unlocking assembly 40 moves along the preset direction OO' to drive the plurality of clamping arms 31 to slide relative to the support 10 towards the connecting member 20 until they abut against the connecting member 20, causing the plurality of clamping arms 31 to perform multi-sided clamping on the connecting member 20 and be in the above-mentioned first state. At this time, the position between the connecting member 20 and the support 10 is relatively fixed, and rapid installation can be achieved. On the contrary, the unlocking assembly 40 moves along the preset direction OO' to drive the plurality of clamping arms 31 to slide relative to the support 10 away from the connecting member 20 until they are disengaged from the connecting member 20, causing the plurality of clamping arms 31 to perform multi-sided loosening on the connecting member 20 and be in the above-mentioned second state. At this time, the position between the connecting member 20 and the support 10 can be relatively changed, and rapid disassembly can be achieved. Another example is that when the plurality of clamping arms 31 are rotatably connected to the support 10, the unlocking assembly 40 moves along the preset direction OO' to drive the plurality of clamping arms 31 to rotate relative to the support 10 towards the direction biased towards the connecting member 20 until they abut against the connecting member 20, causing the plurality of clamping arms 31 to perform multi-sided clamping on the connecting member 20 and be in the above-mentioned first state. At this time, the position between the connecting member 20 and the support 10 is relatively fixed, and rapid installation can be achieved. On the contrary, the unlocking assembly 40 moves along the preset direction OO' to drive the plurality of clamping arms 31 to rotate relative to the support 10 towards the direction deviating from the connecting member 20 until they are disengaged from the connecting member 20, causing the plurality of clamping arms 31 to perform multi-sided loosening on the connecting member 20 and be in the above-mentioned second state. At this time, the position between the connecting member 20 and the support 10 can be relatively changed, and rapid disassembly can be achieved.

[0038] Based on the quick-release device 1 in the embodiment of the present application, by designing the cooperation between the unlocking assembly 40 and the plurality of clamping arms 31, the movement of the unlocking assembly 40 can drive the plurality of clamping arms 31 to move, so that the plurality of clamping arms 31 perform multi-sided clamping on the connecting member 20 and are in the first state. In this way, the relative position between the connecting member 20 and the support 10 can be fixed, thereby achieving the rapid installation of the photographic device connected to the connecting member 20. By designing the cooperation between the unlocking assembly 40 and the plurality of clamping arms 31, the movement of the unlocking assembly 40 can drive the plurality of clamping arms 31 to move, so that the plurality of clamping arms 31 perform multi-sided loosening on the connecting member 20 and are in the second state. In this way, the relative position between the connecting member 20 and the support 10 can be changed, thereby achieving the rapid disassembly of the photographic device connected to the connecting member 20.

[0039] As Figures 4 - 7 shown, when the plurality of clamping arms 31 are rotatably connected to the support 10; the unlocking assembly 40 includes a locking member 41. The locking member 41 is connected to the support 10. The locking member 41 is configured to move along the preset direction OO' to drive the plurality of clamping arms 31 to rotate towards the direction biased towards or away from the connecting member 20, so that the plurality of clamping arms 31 are switched between a first state and a second state.

[0040] Among them, each clamping arm 31 can be, but is not limited to, rotatably connected to the support 10 through a rotating shaft. The multiple clamping arms 31 can be arranged at equal intervals around the circumferential side of the support 10 or can be arranged at unequal intervals around the circumferential side of the support 10; for example, when the number of clamping arms 31 is two, one clamping arm 31 is arranged every 180 degrees in the circumferential direction of the support 10; for another example, when the number of clamping arms 31 is three, one clamping arm 31 is arranged every 120 degrees in the circumferential direction of the support 10; for still another example, when the number of clamping arms 31 is three, two of the clamping arms 31 are separated by 90 degrees in the circumferential direction of the support 10, and the remaining one clamping arm 31 is separated from the two clamping arms 31 by 135 degrees in the circumferential direction of the support 10.

[0041] The locking member 41 serves as the locking member of the unlocking assembly 40; the specific form of the locking member 41 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the locking member 41 can include a main rod (not shown in the figure) and a plurality of branch rods (not shown in the figure) arranged in one-to-one correspondence with the clamping arms 31. One end of each branch rod is connected to the locking member 41, and the other end of each branch rod is rotatably connected to one end of the main rod. The movement of the main rod along the preset direction OO' drives the connected branch rods to push and pull the clamping arms 31, so that the clamping arms 31 rotate in the direction of deviating from or approaching the connecting member 20.

[0042] The locking member 41, as the locking member in the unlocking assembly 40, on the one hand, is used to drive the multiple clamping arms 31 to rotate in the direction of approaching the connecting member 20 until they abut against the connecting member 20, so that the multiple clamping arms 31 clamp the connecting member 20 on multiple sides and are in the above-mentioned first state. At this time, the position between the connecting member 20 and the support 10 is relatively fixed, and rapid installation can be achieved; on the other hand, the locking member 41, as the locking member in the unlocking assembly 40, is used to drive the multiple clamping arms 31 to rotate in the direction of deviating from the connecting member 20 until they are separated from the connecting member 20, so that the multiple clamping arms 31 loosen the connecting member 20 on multiple sides and are in the above-mentioned second state. At this time, the position between the connecting member 20 and the support 10 can change relatively, and rapid disassembly can be achieved.

[0043] Such as Figures 8 - 9As shown, the locking member 41 includes a first collar 411 arranged around a preset direction OO'. The first collar 411 is sleeved on the support 10. And in the first state, the first collar 411 is sleeved on the periphery of all the clamping arms 31. By designing the locking member 41 as the first collar 411 sleeved on the support 10, the first collar 411 moves along the preset direction OO' and gradually approaches the clamping arms 31. The inner circumferential surface of the first collar 411 simultaneously presses the outer sides of the plurality of clamping arms 31, so that the plurality of clamping arms 31 rotate simultaneously in the direction towards the connecting member 20 until the plurality of clamping arms 31 rotate to abut against the connecting member 20 and are in the above-mentioned first state. At this time, the positions between the connecting member 20 and the support 10 are relatively fixed, and thus rapid installation can be achieved. On the contrary, the first collar 411 moves along the preset direction OO' and gradually moves away from the clamping arms 31. The inner circumferential surface of the first collar 411 gradually separates from the outer sides of the plurality of clamping arms 31, so that the plurality of clamping arms 31 rotate simultaneously in the direction away from the connecting member 20 until the plurality of clamping arms 31 rotate to separate from the connecting member 20 and are in the above-mentioned second state. At this time, the positions between the connecting member 20 and the support 10 can be relatively fixed, and thus rapid disassembly can be achieved.

[0044] As Figures 8 - 9 shown, the unlocking assembly 40 further includes an elastic member 42. The elastic member 42 abuts between the locking member 41 and the support 10, and the elastic member 42 is adapted to generate elastic deformation along a direction parallel to the preset direction OO'.

[0045] Among them, the elastic member 42 may but is not limited to include a spring or a spring sheet. There may or may not be a connection relationship between the elastic member 42 and the locking member 41 and / or the support 10. For example, when there is a connection relationship between the elastic member 42 and the locking member 41 and / or the support 10, the elastic member 42 may but is not limited to be detachably connected to the locking member 41 and / or the support 10 by at least one of the ways such as screwing, clamping or plugging. Another example is that when there is a connection relationship between the elastic member 42 and the locking member 41 and / or the support 10, the elastic member 42 may also but is not limited to be non-detachably connected to the locking member 41 and / or the support 10 by means of gluing.

[0046] By designing the elastic member 42 to abut between the locking member 41 and the support 10, the elastic member 42 always has an elastic restoring force. In the first state, the locking member 41 always has a tendency to move closer to the clamping arms 31 under the action of this elastic restoring force. In this way, the stability of the locking member 41 fixing all the clamping arms 31 in the first state can be effectively enhanced. In addition, when it is necessary to disassemble the connecting member 20, the acting force on the locking member 41 needs to overcome the elastic restoring force of the elastic member 42 to make the locking member 41 move along the preset direction OO' and gradually move away from the clamping arms 31, so as to achieve rapid disassembly.

[0047] Specifically, in the embodiment of the present application, the elastic member 42 includes a spring, which is arranged around the support 10, and the spring is pressed tightly between the first ring 411 and the support 10. In this way, the spring always has an elastic restoring force; in the first state, the first ring 411 always has a tendency to move closer to the clamp arm 31 under the action of the elastic restoring force, which can effectively enhance the stability of the first ring 411 being sleeved around the periphery of all the clamp arms 31 in the first state; in addition, when it is necessary to disassemble the connector 20, the force acting on the first ring 411 needs to overcome the elastic restoring force of the spring to make the first ring 411 move along the preset direction OO' and gradually move away from the clamp arm 31, thereby achieving rapid disassembly.

[0048] like Figures 3 - 7 As shown, the quick release device 1 further includes a cartridge seat 50, which covers the support 10 and forms a receiving chamber 51 together with the support 10; all the clamp arms 31 are located in the receiving chamber 51; and part of the connecting member 20 passes through the cartridge mouth of the cartridge seat 50 and extends into the receiving chamber 51. The release assembly 40 further includes a release member 43, at least part of which is located outside the receiving chamber 51, and the release member 43 is connected to the locking member 41, and the release member 43 is configured to drive the locking member 41 to move along a preset direction OO' to drive the plurality of clamp arms 31 to rotate in a direction biased toward or away from the connecting member 20.

[0049] The cartridge seat 50 serves as the outer shell of the quick-release device 1 . The specific structure of the cartridge seat 50 is not limited here, and designers can make reasonable designs according to actual needs.

[0050] The release member 43 serves as a releasing member of the release assembly 40 , and the release member 43 may be, but is not limited to, a block structure (such as a shift block), a rod structure (such as a shift lever) or a ring structure (such as the second ring 431 described below).

[0051] It should be noted that the unlocking member 43 can be used only to drive the locking member 41 to move along the preset direction OO', and make the locking member 41 gradually approach the clamping arms 31, so that the locking member 41 drives the plurality of clamping arms 31 to rotate towards the direction of the connecting member 20 until they abut against the connecting member 20 (at this time, the elastic restoring force of another spring different from the above elastic member 42 can be used to drive the locking member 41 to move along the above preset direction OO' and make the locking member 41 gradually move away from the clamping arms 31, so that the locking member 41 drives the plurality of clamping arms 31 to rotate away from the connecting member 20 until they are disengaged from the connecting member 20; when the plurality of clamping arms 31 are in the first state, the locking member 41 is positioned by a clamping structure such as a wedge block, and the other spring has an elastic restoring force. When quick disassembly is required, the wedge block can release the locking member 41); it can also be that the unlocking member 43 is only used to drive the locking member 41 to move along the preset direction OO', and make the locking member 41 gradually move away from the clamping arms 31, so that the locking member 41 drives the plurality of clamping arms 31 to rotate away from the connecting member 20 until they are disengaged from the connecting member 20 (at this time, the elastic restoring force of the elastic member 42 can be used to drive the locking member 41 to move along the above preset direction OO' and make the locking member 41 gradually approach the clamping arms 31, so that the locking member 41 drives the plurality of clamping arms 31 to rotate towards the direction of the connecting member 20 until they abut against the connecting member 20); it can also be that the unlocking member 43 is used both to drive the locking member 41 to move along the preset direction OO', and make the locking member 41 gradually approach the clamping arms 31, so that the locking member 41 drives the plurality of clamping arms 31 to rotate towards the direction of the connecting member 20 until they abut against the connecting member 20, and to drive the locking member 41 to move along the preset direction OO', and make the locking member 41 gradually move away from the clamping arms 31, so that the locking member 41 drives the plurality of clamping arms 31 to rotate away from the connecting member 20 until they are disengaged from the connecting member 20.

[0052] By designing the unlocking member 43, the unlocking member 43 drives the locking member 41 to move along the preset direction OO', so that the locking member 41 drives the plurality of clamping arms 31 to rotate towards the direction of the connecting member 20 until they abut against the connecting member 20, and the relative position between the connecting member 20 and the support 10 is fixed, and thus quick installation can be achieved; by designing the unlocking member 43, the unlocking member 43 drives the locking member 41 to move along the preset direction OO', so that the locking member 41 drives the plurality of clamping arms 31 to rotate away from the connecting member 20 until they are disengaged from the connecting member 20, and the relative position between the connecting member 20 and the support 10 can be changed, and thus quick disassembly can be achieved.

[0053] It is worth mentioning that, as Figure 1 shown, in the related art, since the inner diameter dimension of the housing 10' is larger than the radial dimension of the worm 20', the worm 20' is likely to tilt, resulting in the lower end of the worm 20' scratching the inner wall of the housing 10', thereby causing damage to the inner wall of the housing 10'. However, as Figures 4 - 7As shown, in the present application, when the clamping arms 31 are in the first state, they can clamp and fix the connecting member 20 on multiple sides to support the connecting member 20 on multiple sides. In this way, the possibility of the connecting member 20 tilting can be effectively reduced or even avoided, thereby reducing or even avoiding the possibility of the inner wall of the barrel seat 50 being scratched by the bottom end of the connecting member 20 and causing damage to the barrel seat 50.

[0054] As Figures 3 - 7 shown, the unlocking member 43 includes a second collar 431 arranged around the preset direction OO'. The second collar 431 is sleeved on the periphery of the barrel seat 50 and is connected to the locking member 41. By designing the second collar 431, the second collar 431 moves along the preset direction OO' to drive the connected locking member 41 to move along the preset direction OO' and gradually approach the clamping arms 31, so that the multiple clamping arms 31 simultaneously rotate towards the direction of the connecting member 20 and abut against the connecting member 20, realizing the relative fixation of the position between the connecting member 20 and the support 10, and thus realizing rapid installation; by designing the second collar 431, the second collar 431 moves along the preset direction OO' to drive the connected locking member 41 to move along the preset direction OO' and gradually move away from the clamping arms 31, so that the multiple clamping arms 31 simultaneously rotate away from the connecting member 20 and disengage from the connecting member 20, enabling the relative position between the connecting member 20 and the support 10 to change, and thus realizing rapid disassembly.

[0055] As Figures 3 - 7 shown, the barrel side wall of the barrel seat 50 is provided with a long strip-shaped through hole 52 extending along the preset direction OO'; the unlocking member 43 is provided with a through hole 432 corresponding to the long strip-shaped through hole 52; the unlocking assembly 40 further includes a fastener 44, and the fastener 44 passes through the through hole 432 and is connected to the locking member 41.

[0056] Among them, the specific connection method between the fastener 44 and the locking member 41 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the fastener 44 can be but not limited to being connected to the locking member 41 by screwing, clamping or plugging.

[0057] By designing the fastener 44, the fastener 44 is equivalent to the connecting member 20 of the locking assembly for connecting the locking member 41 and the unlocking member 43. An external force acts on the unlocking member 43 to make the unlocking member 43 move along the preset direction OO'. The movement of the unlocking member 43 drives the locking member 41 to also move synchronously along the preset direction OO' through the fastener 44. Such an operation is simple and can realize rapid disassembly and assembly.

[0058] It can be understood that for different specific forms of the fastener 44, the specific connection method between the fastener 44 and the locking member 41 is also different; the specific forms of the fastener 44 can be but not limited to the following several embodiments.

[0059] In the first embodiment, the fastener 44 includes a fastening screw 441, and the fastening screw 441 passes through the through hole 432 and is threadedly connected to the locking member 41. In this way, the connection between the unlocking member 43 and the locking member 41 is realized by locking the screw. When an external force acts on the unlocking member 43 to make the unlocking member 43 move along the preset direction OO', the movement of the unlocking member 43 drives the locking member 41 to move synchronously along the preset direction OO' through the fastening screw 441. Such an operation is simple and can achieve quick disassembly and assembly.

[0060] In the second embodiment, the fastener 44 includes a retaining pin (not shown in the figure), and the retaining pin passes through the through hole 432 and is snap-fitted to the locking member 41. In this way, the connection between the unlocking member 43 and the locking member 41 is realized by snap-fitting the retaining pin. When an external force acts on the unlocking member 43 to make the unlocking member 43 move along the preset direction OO', the movement of the unlocking member 43 drives the locking member 41 to move synchronously along the preset direction OO' through the retaining pin. Such an operation is simple and can achieve quick disassembly and assembly.

[0061] In the third embodiment, the fastener 44 includes a plug pin (not shown in the figure), and the plug pin passes through the through hole 432 and is inserted into the locking member 41. In this way, the connection between the unlocking member 43 and the locking member 41 is realized by inserting the plug pin. When an external force acts on the unlocking member 43 to make the unlocking member 43 move along the preset direction OO', the movement of the unlocking member 43 drives the locking member 41 to move synchronously along the preset direction OO' through the plug pin. Such an operation is simple and can achieve quick disassembly and assembly.

[0062] As Figure 9 shown, the clamping assembly 30 further includes a plurality of torsion springs 32 corresponding to the plurality of clamping arms 31 one by one. One end of each torsion spring 32 is connected to the corresponding clamping arm 31, and the other end of each clamping arm 31 is connected to the support 10. By designing the torsion spring 32, when the locking member 41 drives the plurality of clamping arms 31 to rotate towards the direction of the connecting member 20 and abuts against the connecting member 20, the torsion spring 32 undergoes elastic deformation and has an elastic restoring force; when quick disassembly is required, the locking member 41 drives the plurality of clamping arms 31 to rotate away from the connecting member 20, and the clamping arms 31 are quickly reset under the action of the elastic restoring force of the torsion spring 32.

[0063] As Figure 3As shown, the quick-release device 1 further includes a grip member 60, and the grip member 60 is connected to the support 10. Among them, the grip member 60 can be, but is not limited to, a handle or a bracket; the specific connection method between the grip member 60 and the support 10 is not limited here, and designers can make reasonable designs according to actual needs; for example, the grip member 60 can be, but is not limited to, detachably connected to the support 10 by at least one of screwing, clamping or plugging; for another example, the grip member 60 can also be, but is not limited to, non-detachably connected to the support 10 by gluing, 3D printing or injection molding. By designing the grip member 60, it is convenient for users to hold for relevant shooting.

[0064] In a second aspect, an embodiment of the present application provides a photography system, which includes a pan-tilt head (not shown in the figure) and the above-mentioned quick-release device 1; the pan-tilt head is used to mount a photographic device, and the pan-tilt head and the quick-release device 1 are detachably connected through a connecting member 20.

[0065] Based on the shooting system in the embodiment of the present application, with the above-mentioned quick-release device 1, it is possible to achieve the quick installation and quick disassembly of the pan-tilt head connected to the connecting member 20, thereby achieving the quick installation and quick disassembly of the photographic device.
