Quick-release mounts and quick-release components

Abstract

This invention relates to a quick-release base and a quick-release assembly. The quick-release assembly includes a quick-release base and a quick-release plate. The quick-release base includes a base body, a clamping assembly, and a drive assembly. The clamping assembly includes a clamping part and a locking part, used for clamping or releasing the quick-release plate during gimbal replacement. The drive assembly includes a drive part and a self-aligning part. As the drive part rotates to move the clamping part closer to or away from the clamping part, the drive part and the locking part experience contact wear. The self-aligning part can adjust the rotation center of the drive part to be closer to or further away from the clamping part to compensate for the contact wear between the drive part and the locking part, allowing the quick-release base to better lock or release the quick-release plate.

Description

Technical Field

[0001] This invention relates to the field of photographic aids technology, and in particular to a quick-release mount and quick-release assembly. Background Technology

[0002] A gimbal is a support device for photographic equipment such as cameras and camcorders, used to mount and fix the lens of the equipment. A gimbal consists of a quick-release plate and a base. The quick-release plate is used to mount the camera, and the base is used to secure the quick-release plate. For a better shooting experience, it is necessary to frequently change cameras or camera lenses, thus requiring the quick-release plate to be replaced as needed. While existing gimbal bases on the market can effectively install and remove quick-release plates, enabling quick-release plate replacement, friction and wear can cause the locking parts to fail to engage properly during the installation and locking process. For example, CN212004834U discloses a self-ejecting quick-release plate structure. When the locking knob is rotated several times to engage with the latch and lock the quick-release plate to its maximum extent, the spatial position of the latch and the locking rotation is relatively fixed. However, during the back-and-forth movement of the locking knob engaging and releasing the latch, the mass of the outer side of the latch and the end of the locking knob gradually wears away. Over time, the degree of engagement between the two decreases, making it impossible to lock the quick-release plate securely. Of course, in another usage scenario, when the locking knob releases the quick-release plate by rotating it several times against the latch, the outer side of the latch and the end of the locking knob may also experience wear, causing the quick-release plate to fail to release completely. Summary of the Invention

[0003] The present invention provides a quick-release base and quick-release assembly to solve the technical problem that the quick-release plate is difficult to lock or release due to wear of parts caused by long-term disassembly and assembly of the quick-release plate in the gimbal.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention provides a quick-release mount, comprising:

[0006] seat body;

[0007] A clamping assembly is disposed on the base body. The clamping assembly includes a clamping part and a locking part. The locking part is capable of approaching and moving away from the clamping part to clamp and release the quick-release plate in the clamping assembly.

[0008] A drive assembly is disposed on the base body. The drive assembly includes a drive part and a centering part. The drive part is used to rotate and drive the locking part closer to the clamping part when it contacts the locking part. The centering part can adjust the rotation center of the drive part to be closer to the clamping part.

[0009] In one embodiment, the self-aligning part includes a self-aligning shaft and a linkage member, the linkage member being disposed between the self-aligning shaft and the driving part; the self-aligning shaft is rotatable relative to the base body to drive the linkage member to move along the axial direction of the self-aligning shaft, and when the linkage member moves along the self-aligning shaft, the linkage member drives the driving part to move closer to the clamping part.

[0010] In one embodiment, the self-aligning shaft is provided with an external thread, the linkage is provided with an internal thread, and the self-aligning shaft and the linkage are connected by thread engagement.

[0011] In one embodiment, the axial direction of the self-aligning shaft is perpendicular to the moving direction of the locking part, and the linkage includes a gradient part. Along the axial direction of the self-aligning shaft, the radial dimension of the gradient part gradually increases or decreases. When the self-aligning shaft rotates in the positive direction relative to the seat, the gradient part drives the driving part to move closer to the clamping part.

[0012] In one embodiment, the axial direction of the self-aligning shaft is inclined to the direction of movement of the locking part, and both the external thread and the internal thread extend at an angle.

[0013] In one embodiment, the base is provided with an anti-deflection groove, the linkage is provided with an anti-deflection block, and the anti-deflection block is disposed in the anti-deflection groove.

[0014] In one embodiment, the linkage is sleeved on the self-aligning shaft, the drive unit is sleeved on the linkage, and the drive unit is rotatable around the self-aligning unit.

[0015] In one embodiment, the self-aligning part includes a guide structure, a linkage member, and an adjusting member. The guide structure is fixed relative to the seat body, and the linkage member is disposed between the driving part and the guide structure. The adjusting member is movable relative to the seat body to drive the linkage member to slide along the guide structure, thereby driving the driving part closer to the clamping part.

[0016] In one embodiment, the adjusting member includes a threaded member that is threaded through the seat and its end abuts against the linkage member. The threaded member is rotatable relative to the seat so that the adjusting member drives the driving part closer to the clamping part.

[0017] In one embodiment, the self-aligning component further includes a reset component, which is disposed between the linkage component and the base body. The reset component can release a reset force to drive the linkage component closer to the clamping part.

[0018] In one embodiment, the guide structure is characterized by its axial orientation being inclined to the direction of movement of the locking portion.

[0019] In one embodiment, the quick-release base includes a first elastic element disposed between the base body and the locking part. During the movement of the driving part rotating relative to the base body and pressing the locking part closer to the clamping part, the quick-release plate is clamped between the locking part and the clamping part, and the first elastic element accumulates elastic force. During the process of the driving part rotating in the opposite direction relative to the base body, the first elastic element releases the elastic force to drive the locking part away from the clamping part, thereby releasing the quick-release plate.

[0020] In one embodiment, the locking part can be triggered by a single button to perform a flipping and moving action toward the side where the clamping part is located, so as to clamp the quick-release plate between the locking part and the clamping part.

[0021] In one embodiment, the drive unit includes a cam, and the quick-release seat further includes a second elastic element disposed between the cam and the seat body; before the locking part completes the flipping action, the locking part is engaged with the cam, and the second elastic element accumulates elastic force; after the locking part completes the flipping action, the engagement between the locking part and the cam is released, and the second elastic element releases elastic force to drive the cam to rotate, and the cam drives the locking part to move toward the clamping part by rotating.

[0022] In a second aspect, the present invention provides a quick-release mount, comprising:

[0023] seat body;

[0024] A clamping assembly is disposed on the base body. The clamping assembly includes a clamping part and a locking part. The locking part is capable of approaching and moving away from the clamping part to clamp and release the quick-release plate in the clamping assembly.

[0025] A drive assembly is disposed on the base body. The drive assembly includes a drive part and a centering part. The drive part is used to rotate the locking part away from the clamping part when it contacts the locking part. The centering part can adjust the rotation center of the drive part to be further away from the clamping part.

[0026] In one embodiment, the self-aligning part includes a self-aligning shaft and a linkage member, the linkage member being disposed between the self-aligning shaft and the driving part; the self-aligning shaft is rotatable relative to the base body to drive the linkage member to move along the axial direction of the self-aligning shaft, and when the linkage member moves along the self-aligning shaft, the linkage member drives the driving part away from the clamping part.

[0027] In one embodiment, the self-aligning shaft is provided with an external thread, the linkage is provided with an internal thread, and the self-aligning shaft and the linkage are connected by thread engagement.

[0028] In one embodiment, the axial direction of the self-aligning shaft is perpendicular to the moving direction of the locking part, and the linkage includes a gradient part. Along the axial direction of the self-aligning shaft, the radial dimension of the gradient part gradually increases or decreases. When the self-aligning shaft rotates in the positive direction relative to the seat, the gradient part drives the driving part away from the clamping part.

[0029] In one embodiment, the axial direction of the self-aligning shaft is inclined to the direction of movement of the locking part, and both the external thread and the internal thread extend at an angle.

[0030] In one embodiment, the base is provided with an anti-deflection groove, the linkage is provided with an anti-deflection block, and the anti-deflection block is disposed in the anti-deflection groove.

[0031] In one embodiment, the linkage is sleeved on the self-aligning shaft, the drive unit is sleeved on the linkage, and the drive unit is rotatable around the self-aligning unit.

[0032] In one embodiment, the self-aligning part includes a guide structure, a linkage member, and an adjusting member. The guide structure is fixed relative to the seat body, and the linkage member is disposed between the driving part and the guide structure. The adjusting member is movable relative to the seat body to drive the linkage member to slide along the guide structure, thereby driving the driving part away from the clamping part.

[0033] In one embodiment, the adjusting member includes a threaded member that is threaded through the seat and its end abuts against the linkage member. The threaded member is rotatable relative to the seat so that the adjusting member drives the driving part away from the clamping part.

[0034] In one embodiment, the self-aligning component further includes a reset component disposed between the linkage component and the base body. The reset component is capable of releasing a reset force to drive the linkage component away from the clamping portion.

[0035] In one embodiment, the axial direction of the guide structure is inclined to the direction of movement of the locking part.

[0036] Thirdly, the present invention provides a quick-release assembly, including a quick-release plate and the quick-release base, wherein the quick-release plate is clamped between the clamping part and the locking part.

[0037] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0038] This invention provides a quick-release base and quick-release assembly. During the process of changing the quick-release plate using a gimbal device, the locking part and the driving part are constantly in contact and rubbing against each other. As the quick-release base is used for longer periods, the locking part and the driving part experience wear and tear, causing the quick-release base to fail to fully lock or release the quick-release plate. This solution addresses this by using a self-aligning part to adjust the rotation center of the driving part closer to or further away from the clamping part. In other words, the quick-release base can compensate for the wear and tear of the driving part through the adjustment of the self-aligning part, thus better locking or releasing the quick-release plate. Compared to the gimbal quick-release plate self-ejection structure without a self-aligning structure disclosed in CN212004834U, the wear and tear of the locking knob cannot be compensated during quick-release plate replacement, causing the quick-release base in that solution to fail to fully lock or release the quick-release plate after a period of use. This solution, with its self-aligning structure, significantly extends the service life of the quick-release base. Attached Figure Description

[0054] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] refer to Figure 1 This invention provides a quick-release mount 10 with a self-aligning structure that facilitates installation and disassembly. The quick-release mount 10 is primarily used in gimbal devices within the field of photographic support and auxiliary equipment. It is used to install and lock the quick-release plate 20. This quick-release mount 10 not only allows customers to easily install and lock the quick-release plate 20 with a single trigger action when changing cameras and lenses on the gimbal, but also solves the problem of difficulty in locking or releasing the quick-release plate due to wear and tear from frequent installation and removal during gimbal use. This invention enables gimbal devices to more easily and quickly change different types of quick-release plates 20, thereby facilitating faster changes to different types of lenses and cameras. Simultaneously, the self-aligning structure compensates for component wear, extending the lifespan of the quick-release mount 10 and providing customers with a better shooting experience. Figure 1 A quick-release assembly 1 is illustrated, comprising a quick-release base 10 and a quick-release plate 20. The quick-release base 10 is used to clamp and lock the quick-release plate 20. The quick-release base 10 can be mounted on other external devices or directly supported on a support surface. It should be noted that in this design, the type of quick-release plate 20 connected to the quick-release base 10 is not limited; the quick-release plate 20 should be interpreted broadly in this application, encompassing any external device or sheet material that can mate with the quick-release base 10.

[0056] refer to Figure 2 The quick-release base 10 includes a base 100, a clamping component 200, and a drive component 300. The base 100 serves as a supporting body. The clamping component 200 is disposed on the base 100 and forms a clamping space. The quick-release base 10 clamps the quick-release plate 20 within the clamping space. The drive component 300 is disposed on the base 100 and is in contact with the clamping component 200. The drive component 300 can change the size of the clamping space and increase or decrease the clamping force by rotating and translating relative to the base 300, so as to lock or release the quick-release plate 20.

[0057] The base 100 has an interconnected mounting cavity 111 and a clearance notch 112. The mounting cavity 111 is used for mounting a portion of the clamping assembly 200 to the drive assembly 300. The clearance notch 112 is used for a portion of the clamping assembly 200 to protrude from the base 100, allowing the portion of the clamping assembly 200 to move relative to the base 100 within the clearance notch 112. In one embodiment, the base 100 includes a base 110 and a cover plate 120. The cover plate 120 is detachably connected to the base 110 and encloses it to form the mounting cavity 111 described above. In this case, the clearance notch 112 is formed in the base 110.

[0058] The clamping assembly 200 includes a clamping part 210 and a locking part 220. The clamping part 210 protrudes from one side of the base 100, and the locking part 220 is movably disposed within the mounting cavity 111 on the other side of the base 100, forming a clamping space between the locking part 220 and the clamping part 210. The driving assembly 300 can rotate to move the locking part 220 closer to or further away from the clamping part 210, thereby changing the size of the clamping space and clamping or releasing the quick-release plate 20. It should be noted that the shape and location of the clamping part 210 are not limited. The clamping part 210 can be located at the edge of the base 100, or it can protrude from the inside of the base 100, as long as the clamping part 210 and the locking part 220 form a clamping space capable of clamping the quick-release plate 20. In one embodiment, Figure 1 The diagram illustrates that the clamping part 210 is connected to the base 110 and disposed on the edge of the base 110, so as to make full use of the installation space of the base 110, making the quick-release base 10 more compact overall. It is understood that in other embodiments, the clamping part 210 may also be disposed on the inner side of the base 110. Additionally, Figure 1 It is also shown that the clamping part 210 is provided with a dovetail groove 211 on the side facing the locking part 220. The dovetail groove 211 is used to cooperate with the quick-release plate 20 with the dovetail structure to improve the stability of the quick-release plate 20 after installation.

[0059] refer to Figure 2 The locking part 220 is disposed in the mounting cavity 111 and movable in the clearance notch 112. The locking part 220 can be triggered by one key to switch the quick mount 10 between the loose state and the locked state. Figure 3 This indicates that the quick-release base 10 is in the released state. At this time, the locking part 220 and the clamping part 210 are far apart. A portion of the structure of the locking part 220 protrudes from the base body 100, so that the user can press the protruding portion of the locking part 220 with the quick-release plate 20, causing the locking part 220 to be triggered and move closer to the clamping part 210, clamping the quick-release plate 20 between the locking part 220 and the clamping part 210. At this time, the quick-release base 10 is switched to... Figure 4The locking state is shown. It should be explained that pressing the protruding structure of the locking part 220 is only one specific triggering method. Here, the triggering method is not limited, as long as it can switch the quick-release seat 10 between the loose and locked states by triggering the locking part 220 with one button.

[0060] In one embodiment, the locking part 220 can be triggered by a single button to sequentially perform a flipping and moving action toward the side where the clamping part 210 is located, thereby clamping the quick-release plate 20 between the clamping part 210 and the locking part 220. Therefore, during the replacement of the quick-release plate 20, this application only requires a single triggering action to install and lock the quick-release plate 20. Compared to the process of first triggering the locking part 220 and then rotating the locking knob back and forth to install and lock the quick-release plate 20, this solution only requires a single button triggering of the locking part 220 to sequentially perform a flipping and moving action toward the side where the clamping part 210 is located, thereby clamping the quick-release plate 20 between the clamping part 210 and the locking part 220. This solution significantly simplifies the operation steps. This solution ensures quick replacement of the quick-release plate 20 while also enabling the installation and locking of the quick-release plate with a single triggering action. Furthermore, since the locking part 220 can not only flip toward the side where the clamping part 210 is located to approach the clamping part 210, but also can move toward the side where the clamping part 210 is located to approach the clamping part 210, the locking part 220 in this solution can more securely clamp the quick-release plate 20 between the clamping part 210 and the locking part 220.

[0061] Reference Figure 2 and Figure 5 The quick-release seat 10 also includes a second elastic element 400, and the drive assembly 300 includes a drive assembly 310, which can be implemented as a cam 311. Figure 2 As shown, cam 311 is rotatably connected to base 100. Figure 2The diagram illustrates that cam 311 is rotatably connected to cover plate 120 and housed within mounting cavity 111. A second elastic element 400 is positioned between cam 311 and cover plate 120. Before locking part 220 is pressed and flipped by quick-release plate 20, locking part 220 engages with cam 311, at which point the second elastic element 400 accumulates elastic force. After locking part 220 completes its flipping action by being pressed by quick-release plate 20, the second elastic element 400 releases its elastic force, causing cam 311 to rotate. Cam 311 then moves locking part 220 toward clamping part 210, clamping quick-release plate 20 between clamping part 210 and locking part 220. The cam 311 has a radially varying drive surface that contacts locking part 220, for example, gradually increasing or decreasing in size. The second elastic element 400 can be a torsion spring as shown in the diagram, with its two ends connected to cam 311 and cover plate 120, respectively. Before the locking part 220 is pressed and flipped by the quick-release plate 20, in order to achieve the engagement of the locking part 220 with the cam 311, in one embodiment, refer to Figure 5 The edge of the cam 311 is provided with a slot 312, and the locking part 220 is provided with a limit block 221. When the quick-release seat 10 is in the loose state, that is, before the locking part 220 is flipped, the limit block 221 is engaged in the slot 312, so that the limit block 221 can restrict the rotation of the cam 311.

[0062] Continue to refer to Figure 5 The locking part 220 includes a clamping block 220a and a limiting block 221 connected together. The clamping block 220a passes through the clearance notch 112 and can flip within the clearance notch 112. The limiting block 221 engages with the cam 311. When the clamping block 220a is pressed by the quick-release plate 20, it causes the locking part 220 to flip. At the same time, the limiting block 221 also flips and disengages from the cam 311. Then, the cam 311 rotates under the elastic force of the second elastic member 400 to squeeze the clamping block 220a closer to the clamping part 220, thereby clamping the quick-release plate 20 between the clamping part 210 and the clamping block 220. In one embodiment, Figure 6 The diagram illustrates that the clamping block 220a includes a rotating shaft 222, a locking claw 223, and a trigger block 224, and the three components of the rotating shaft 222, the locking claw 223, and the trigger block 224 can move synchronously. Figure 7 The diagram illustrates that the rotating shaft 222 is movably disposed within the mounting cavity 111, and the rotating shaft 222 is capable of rotating and moving relative to the base 100. Figure 3The diagram illustrates that the locking pawl 223 passes through the clearance notch 112 and can rotate within the clearance notch 112. The trigger block 224 is located inside the locking pawl 223 and protrudes from the base 100. The trigger block 224 can be pressed by the quick-release plate 20 to drive the locking pawl 223 and the rotating shaft 222 to rotate around the central axis of the rotating shaft 222. After the locking pawl 223 completes its rotation, the cam 311 rotates, causing the locking pawl 223 to move closer to the clamping part 210, clamping the quick-release plate 20 between the clamping part 210 and the locking pawl 223.

[0063] refer to Figure 2 On the one hand, the drive unit 310 rotates to drive the locking part 220 closer to the clamping part 210 to lock the quick-release plate 20; on the other hand, the drive assembly 300 also includes a centering part 320. When the drive unit 310 contacts the locking part 220, it rotates to drive the locking part 220 closer to the clamping part 210. The drive assembly 300 can adjust the rotation center of the drive unit 310 to be closer to the clamping part 210 through the centering part 320, so that the locking part 220 is closer to the clamping part 210, thereby reducing the clamping space and locking the quick-release plate 20. Therefore, the drive assembly 300 provides driving force for the quick-release base 10 to lock the quick-release plate 20 by triggering the locking part 220 with one button. However, during the replacement of the quick-release plate 20, the locking part 220 and the drive part 310 are constantly in contact and rubbing against each other. As the quick-release base 10 is used for longer periods, the locking part 220 and the drive part 310 experience wear, making it impossible for the quick-release base 10 to fully lock the quick-release plate 20. This solution incorporates a self-aligning part 320 to adjust the rotation center of the drive part 310 closer to the clamping part 210. This means the quick-release base 10 can compensate for the wear of the drive part 310 through the adjustment of the self-aligning part 320, thus better locking the quick-release plate 10. Compared to a quick-release base 10 without a self-aligning part 320, the quick-release base 10 in this solution significantly extends its service life due to the inclusion of the self-aligning part 320.

[0064] It should be explained that the quick-release base 10 is only one specific embodiment and environmental device of the self-aligning part 320 in this invention. The self-aligning part 320 can be used in any other device that needs to adjust the relative position of parts to compensate for wear, as long as the structure can meet the requirements for installing the self-aligning part 320. Furthermore, even if the self-aligning part 320 is only used in the quick-release base 10 to compensate for wear of parts and better lock the quick-release plate 10, this invention does not limit the process of the quick-release base 10 locking the quick-release plate 20. It only needs to satisfy the movement process of the locking part 220 moving closer to or away from the clamping part 210. This allows the self-aligning part 320 to adjust the rotation center position of the driving part 310 to compensate for wear, enabling the quick-release base 10 to better lock the quick-release plate 20. This can be understood as follows: in embodiments with a self-aligning function, the locking process of the quick-release seat 10 does not require the aforementioned flipping and then moving action. For example, in embodiments where the locking part 220 is locked simply by moving closer to the clamping part 210, or in embodiments where the locking part 220 is locked simply by flipping closer to the clamping part 210, the quick-release seat 10 with the self-aligning part 320 of the present invention should be protected.

[0065] The self-aligning part 320 includes a self-aligning shaft 321 and a linkage 322. The linkage 322 is disposed between the self-aligning shaft 321 and the drive part 310, and the drive part 310 is capable of rotating around the self-aligning part 320. For details, refer to the reference. Figure 2 and Figure 5 The linkage 322 is sleeved on the self-aligning shaft 321, and the drive unit 310 is sleeved on the linkage 322, thus making the overall structure of the drive assembly more compact. It is understood that in other embodiments, when structural compactness is not a concern, the drive unit 310, linkage 322, and self-aligning shaft 321 can be arranged in a non-sleeving manner. The self-aligning shaft 321 can rotate relative to the base 100 in the forward direction, driving the linkage 322 to move along the axial extension direction of the self-aligning shaft 321. During the movement of the linkage 322, it can simultaneously drive the drive unit 310 closer to the clamping part 210, so that when the locking part 220 contacts the drive unit 210, it can be driven by the drive unit 210 to move closer to the clamping part 210, compensating for the mass wear of the drive unit 210 and allowing the quick-release base 10 to fully lock the quick-release plate 20. Figure 2 The diagram illustrates that the self-aligning shaft 321 is provided with an external thread, and the linkage 322 is provided with an internal thread, allowing the self-aligning shaft 321 and the linkage 322 to be connected via threaded engagement; furthermore... Figure 5 The diagram illustrates that the linkage 322 is equipped with an anti-deflection block 322a. Figure 2The diagram illustrates that an anti-deflection groove 113 is provided inside the mounting cavity 111, and an anti-deflection block 322a is provided in the anti-deflection groove 113 to prevent the linkage 322 from rotating with the rotation of the self-aligning shaft 311. The self-aligning shaft 321 and the linkage 322 can achieve the process of the linkage 322 moving axially with the rotation of the self-aligning shaft 321 by means of threaded engagement with the anti-deflection block 322a of the linkage 322.

[0066] Continue to refer to Figure 2 and Figure 5 In order to enable the axial movement of the linkage 322 to drive the drive unit 210 closer to the clamping unit 210, Figure 2 The diagram shows that the axial direction of the self-aligning shaft 321 is inclined to the direction of movement of the locking part 220, so that the external thread of the self-aligning shaft 321 and the internal thread of the linkage 322 are both inclined. At this time, the linkage 322 can move towards the side where the clamping part 210 is located as the self-aligning shaft 321 rotates, thereby driving the driving part 310 to move closer to the clamping part 220, so that the locking part 220 is closer to the clamping part 210, reducing the clamping space and increasing the clamping force to lock the quick-release plate 20. In other embodiments of this application, the axial direction of the self-aligning shaft 321 may also be perpendicular to the moving direction of the locking part 220. In this case, the linkage 322 includes a gradient part 322b (the radial dimension of the gradient part 322b gradually increases or decreases along the axial direction of the self-aligning shaft 321). When the self-aligning shaft 321 rotates relative to the seat 100, the gradient part 322b can drive the driving part 310 closer to the clamping part 210, making the locking part 220 closer to the clamping part 210, reducing the clamping space, increasing the clamping force, and locking the quick-release plate 20. It should be explained that, as Figure 5 As shown, the linkage 322 also includes a gradient block 322b. The shape of the gradient block 322b is not limited. It can be a cylinder as shown in the figure, or a frustum in other embodiments.

[0067] refer to Figure 5 The quick-release seat 10 also includes a first elastic element 500. Figure 7The illustration shows that the first elastic element 500 is disposed between the base 100 and the locking part 220. During the movement of the drive part 210 relative to the base 100 in a forward direction, pressing the locking part 220 closer to the clamping part 210, the quick-release base 10 clamps the quick-release plate between the clamping part 210 and the locking part 220. At this time, the first elastic element 500 accumulates elastic force. During the movement of the drive part 310 relative to the base 100 in a reverse direction, the first elastic element 500 releases the elastic force, causing the locking part 220 to move away from the clamping part 210, increasing the clamping space, reducing the clamping force, and causing the quick-release base 10 to release the quick-release plate 20. For the sake of consistency, this application defines "forward" as clockwise and "reverse" as counterclockwise. In this application, the first elastic element 500 is disposed between the seat 100 and the rotating shaft 222. When the quick-release plate 20 presses the locking part 220, the locking part 220 can overcome the elastic resistance of the first elastic element 500 and flip over, allowing the first elastic element 500 to accumulate a first elastic force. After the locking part 220 has flipped over, when the drive part 310 rotates and squeezes the locking part 220 to move, the locking part 220 can also overcome the elastic resistance of the first elastic element 500 and move, allowing the first elastic element 500 to accumulate a second elastic force again. It should be explained that... Figure 7 The illustration shows the case of two first elastic elements 500, which are respectively disposed at both ends of the rotating shaft 222. Of course, in other embodiments, the number of first elastic elements 500 can be one or more.

[0068] Reference Figure 3 and Figure 7The first elastic element 500 includes a torsion spring segment 510 and an extension segment 520 that are connected and integrally formed. The torsion spring segment 510 is disposed on the rotating shaft 222, and the extension segment 520 is disposed in the mounting cavity 111 and abuts against the inner wall of the mounting cavity 111. When the locking part 220 is pressed and flipped by the quick-release plate 20, the torsion spring segment 510 rotates and accumulates a first elastic force as the locking claw 312 flips. After the locking part 220 flips and continues to translate and lock the quick-release plate 20, the extension segment 520 is squeezed by the locking part 220 towards the side closer to the clamping part 210 and accumulates a second elastic force. When the quick-release plate 10 releases and loosens the quick-release plate 20, the locking part 220 will successively complete the translation and flipping actions away from the clamping part 210 under the elastic force of the first elastic element 500. Specifically, during the reverse rotation of the drive unit 310 away from the clamping unit 210, the first elastic element 500 releases the second elastic force (released by the extension section 520) and the first elastic force (released by the torsion spring section 510) successively. The locking part 220 can first translate away from the clamping part 210 under the action of the second elastic force, and then flip away from the clamping part 210 under the action of the first elastic force to return to the released state of the quick-release seat 10. At this time, the drive unit 310 stops rotating and engages with the locking part 220. It should be noted that this application does not limit the shape and composition of the first elastic element 500. The first elastic element 500 can be a torsion spring, a spring, an elastic block, or other elastic element capable of generating elasticity, as long as it can accumulate elastic force. The number of times the first elastic element 500 accumulates elastic force is also not limited, as long as at least two processes of accumulating elastic force are achieved. This application uses an integrally molded torsion spring structure as the first elastic element 500, which not only makes the installation of the first elastic element 500 with the mounting cavity 111 and the locking part 220 simple and convenient, and makes the internal structure of the mounting cavity 111 compact, but also effectively realizes the process of continuous two-stage accumulation of elastic force. Compared with using separate torsion springs and springs to accumulate force twice (the torsion spring accumulates the first elastic force, and the spring accumulates the second elastic force, a separate process of force accumulation), this reduces the number of springs required.

[0069] Continue to refer to Figure 7 The mounting cavity 111 also includes a stop block 114 protruding from the inner wall of the mounting cavity 111. The extension section 520 is confined between the inner wall of the mounting cavity 111 and the stop block 114 to prevent the first elastic element 500 from shifting during the accumulation and release of elastic force. It should be noted that the number and shape of the stop blocks 114 are not limited; they can be... Figure 7 The two small cylindrical shapes shown can also be any other geometric shapes protruding from the inner wall of the mounting cavity 111. There can be one, two or more, or even a row, as long as the stop block 114 can prevent the first elastic element 500 from shifting during the accumulation and release of elastic force.

[0070] The quick-release base 10 is also equipped with a handle 600 connected to the cam 311. The handle 600 can drive the cam 311 to rotate, thereby causing the locking part 220 to move closer to or away from the clamping part 210, so as to further lock or release the quick-release plate 20. Specifically, when the quick-release base 10 triggers the locking part 220 to continuously complete the flipping and moving action towards the clamping part 210 by one-button triggering, the quick-release base 10 clamps and locks the quick-release plate 20 between the locking part 220 and the clamping part 210. At this time, turning the handle 600 can drive the cam 311 to rotate further, so that the locking part 220 continues to move closer to the clamping part 210, thereby reducing the clamping space, increasing the clamping force on the quick-release plate 20, and allowing the quick-release base 10 to further clamp the quick-release plate 20.

[0071] When the user needs to release the quick-release plate 20, the user can rotate the cam 311 in the opposite direction by pulling the handle 600. During the reverse rotation of the cam 311, the radial dimension of the gradient surface (the surface whose radial dimension gradually increases or decreases) of the cam 311 that contacts the locking part 220 gradually decreases. At this time, the locking part 220 can return to its original position and move away from the clamping part 210 under the action of the first elastic force released by the first elastic member 500 (referring to the extension section 520), so as to increase the clamping space and reduce the clamping force, thereby releasing the quick-release plate 20. Among them, when the cam 311 rotates in the opposite direction to a certain extent, the locking part 220 flips under the action of the first elastic force released by the first elastic member 500 (referring to the torsion spring section 520) to engage with the cam 311, so that the cam 311 can no longer rotate. The return and flipping of the locking part 220 can further facilitate the quick-release plate 20 to vertically disengage from the quick-release seat 10 along the thickness direction of the quick-release seat 10. During the reverse rotation of the cam 311 driven by the handle 600, the second elastic element 400 can overcome the resistance of the reverse rotation of the cam 311 and accumulate elastic force to provide the driving force for the locking part 220 to move towards the clamping part 210 after being triggered by a single button in the unfolded state. It should be noted that, for the purposes of this application, the handle 600 is only one specific embodiment in which the quick-release base 10 can further lock the quick-release plate 20. The presence or absence of the handle 600 is not limited, nor are the shape and number of the handle 600 limited.

[0072] This invention provides a quick-release base 10 and a quick-release assembly 1. During the process of replacing the quick-release plate 20 using the gimbal device, the locking part 220 and the driving part 310 are constantly in contact and rubbing against each other. As the usage time of the quick-release base 10 increases, the locking part 220 and the driving part 310 experience wear. This causes the quick-release base 10 to be unable to fully lock or release the quick-release plate 20. However, this solution can adjust the rotation center of the driving part 310 to be closer to or further away from the clamping part 210 via the self-aligning part 320. In other words, the quick-release base 10 can compensate for the wear of the driving part 310 through the adjustment of the self-aligning part 320, thus better locking or releasing the quick-release plate 20. Compared to the gimbal quick-release plate self-ejection structure without a self-aligning structure disclosed in CN212004834U, the wear of the locking knob cannot be compensated during the replacement of the quick-release plate 20, causing the quick-release base in this solution to be unable to fully lock or release the quick-release plate 20 after a period of use. This solution, with its self-aligning structure, significantly extends the service life of the quick-release plate 10. Furthermore, when replacing the quick-release plate 20 using the gimbal device, the user only needs a single trigger action to install and lock it. Compared to the process of first triggering the locking part 220 and then repeatedly rotating the locking knob to lock the quick-release plate 20, this solution allows for a single trigger of the locking part 220 to sequentially complete the flipping and moving actions of the locking part towards the clamping part 210, clamping the quick-release plate 20 between the clamping part 210 and the locking part 220. Therefore, this solution ensures that the gimbal device can quickly replace the quick-release plate 20 while also enabling the installation and locking of the quick-release plate 20 with a single trigger action. In addition, since the locking part 220 can not only flip toward the side where the clamping part is located to approach the clamping part 210, but also can move toward the side where the clamping part is located to approach the clamping part 210, the locking part 220 in this solution can more securely clamp the quick-release plate 20 between the clamping part 210 and the locking part 220.

[0073] Second embodiment of quick-release bracket

[0074] The quick-release base 10 in this embodiment has the same basic structure as the quick-release base 10 in the first embodiment. The difference is that after the locking part 220 is triggered by one key, especially during the process of the locking part 220 moving toward the side where the clamping part 210 is located, the locking part 220 will also flip toward the side where the clamping part 210 is located. That is, the moving action and the flipping action of the locking part 220 will be carried out simultaneously.

[0075] refer to Figure 8 and Figure 9In this embodiment, in order to further lock and clamp the quick-release plate 20, the quick-release base 10 is also provided with a sloping protrusion 313 with a gradually changing thickness (the thickness gradually increases or decreases). During the movement of the locking part 220 toward the side where the clamping part 210 is located, the sloping protrusion 313 can be used to drive the locking part 220 to continue to rotate toward the clamping part 210, so that the locking part 220 is closer to the clamping part 210, reducing the clamping space and increasing the clamping force, so as to further clamp the quick-release plate 20 between the locking part 220 and the clamping part 210.

[0076] In this embodiment, Figure 8 The diagram illustrates that when the quick-release base 10 is in the released state, the inclined protrusion 313 is distributed in an arc shape on the edge of the side of the cam 311 opposite to the base 110. The cam 311 is engaged with the locking part 220. After the locking part 220 completes the flipping action with a single key trigger, the locking part 220 and the cam 311 are disengaged. The limiting block 221 tilts upward as the locking part 220 flips, so that the inclined protrusion 313 is clamped between the limiting block 221 and the cam 311. As the cam 311 rotates, causing the locking part 220 to approach the clamping part 210, the thickness of the tapered surface of the inclined protrusion 313 that contacts the limiting block 221 gradually increases. This causes the limiting block 221 to flip towards the side where the clamping part 210 is located. Consequently, the locking part 220 flips towards the side where the clamping part 210 is located as it moves towards the side where the clamping part 210 is located, thereby further clamping the quick-release plate 20 between the locking part 220 and the clamping part 210. At this time, the quick-release seat 10 is in position... Figure 9 The locked state is shown. It should be noted that, for the purposes of this application, the inclined protrusion 313 is only one specific embodiment in which the quick-release seat 10 can further lock the quick-release plate 20. The presence or absence of the inclined protrusion 313 is not limited, nor are the shape and number of the inclined protrusion 313 limited.

[0077] Third embodiment of quick-release bracket

[0078] The quick-release base 10 in this embodiment has the same basic structure as the quick-release base 10 in the first embodiment. The locking part 220 is also triggered by a single button to complete the flipping and moving actions to lock the quick-release plate 20. The difference lies in the fact that the accumulation and release processes of the elastic force of the first elastic member 500 and the second elastic member 330 are different before and after the locking part 300 is triggered by a single button, which makes the driving force source of the locking part 300 approaching the clamping part 200 different.

[0079] Specifically, before the locking part 220 completes its flip, the locking part 220 engages with the cam 311. At this time, the second elastic element 400 accumulates elastic force, and the extension 520 of the first elastic element 500 accumulates second elastic force. When the locking part 220 is pressed and triggered by the quick-release plate 20, the torsion spring segment 510 of the first elastic element 500 accumulates the first elastic force as the locking part 220 completes the flipping action. The locking part 220 is disengaged from the cam 311, and the locking part 220 disengages from the cam 311. The cam 311 can rotate away from the locking part 220 under the action of the elastic force of the second elastic element 400 (during the rotation of the cam 311, the radial dimension of the cam 311 used to contact the locking part 220 gradually decreases). The locking part 220 can approach the clamping part 210 under the action of the second elastic force of the first elastic element 500, so that the quick-release seat 10 clamps and locks the quick-release plate 20 between the locking part 220 and the clamping part 210.

[0080] In this embodiment, when the locking part 220 engages with the cam 311, if the elastic force accumulated by the first elastic member 500 is sufficiently large, after the locking part 220 is triggered to disengage from the cam 311, when the cam 311 rotates to a stationary state under the action of the elastic force of the second elastic member 400 (the elastic force of the first elastic member 500 is fully released), the elastic force of the first elastic member 500 is not fully released, causing the cam 311 to remain in contact with the locking part 220. At this time, the handle 700 can be used to drive the cam 311 to continue rotating away from the locking part 220, while the first elastic member 500 can continue to release its elastic force to drive the locking part 220 to continue moving closer to the clamping part 210, reducing the clamping space and increasing the clamping force to further clamp the quick-release plate. It should be noted that in this embodiment, the cam 311 is disposed between the clamping part 210 and the locking part 220. The first elastic element 500 can be disposed on the side of the clamping part 210 near the locking part 220. In this case, the cam 311, the second elastic element 400 and the first elastic element 500 are disposed on the same side of the locking part 220, thereby making the quick-release seat 10 more miniaturized. In other embodiments, the second elastic element can also be disposed on the side of the locking part 220 away from the clamping part 210.

[0081] When the user needs to release the quick-release plate 20, the user can rotate the cam 311 forward by pulling the handle 700 (during the forward rotation of the cam 311, the radial dimension of the gradient surface of the cam 311 that contacts the locking part 220 gradually increases). At this time, the rotating cam 311 squeezes the locking part 220 to move away from the clamping part 210, thereby increasing the clamping space and reducing the clamping force, thus releasing the quick-release plate 20. When the cam 311 rotates forward to a certain extent, the locking part 220 flips under the action of the first elastic force released by the first elastic element 500 (referring to the torsion spring segment 510) to engage with the cam 311, so that the cam 311 can no longer rotate. The return flip of the locking part 220 can further facilitate the quick-release plate 20 to vertically detach from the quick-release seat 10 along the thickness direction of the quick-release seat 10. During the forward rotation of the cam 311 driven by the handle 700, the second elastic element 400 can overcome the forward rotation resistance of the cam 311 and accumulate elastic force; the first elastic element 500 (referring to the extension section 520) can overcome the movement resistance of the locking part 220 and accumulate the second elastic force to supply the driving force for the locking part 220 to move towards the clamping part 210 after being triggered by a key in the unfolded state.

[0082] To enable the quick-release base 10 to release the quick-release plate 20 more quickly, the cam 311 is provided with a sloping protrusion 313. As the cam 311 rotates and presses the locking part 220 away from the clamping part 210, the sloping protrusion 313 simultaneously causes the locking part 220 to flip towards the side where the clamping part 210 is located, further distancing the locking part 220 from the clamping part 210 and allowing the quick-release base 10 to release the quick-release plate 20 more quickly. It should be noted that, for this embodiment, the presence or absence of the sloping protrusion 313 is not limited, nor are the shape and number of the sloping protrusion 313 limited.

[0083] In this embodiment, the drive assembly 300 is disposed between the clamping part 210 and the locking part 220. The drive part 310 is used to rotate and drive the locking part 220 away from the clamping part 210 when it contacts the locking part 220. The drive assembly 300 can adjust the rotation center of the drive part 310 further away from the clamping part 210 through the self-aligning part 320, so that the locking part 220 is further away from the clamping part 210. Specifically, the self-aligning shaft 321 rotates relative to the base 100 to drive the linkage 322 to move along the axial direction of the self-aligning shaft 321. At the same time, the linkage 322 drives the drive part 310 away from the clamping part 210, so that the locking part 220 in contact with the drive part 310 also moves away from the clamping part 210, allowing the quick-release base 10 to completely release the quick-release plate 10. Therefore, the drive assembly 300 provides driving force for the quick-release base 10 to unlock and release the quick-release plate 20. However, during the replacement of the quick-release plate 20, the locking part 220 and the drive part 310 are constantly in contact and rubbing against each other. As the quick-release base 10 is used for longer periods, the locking part 220 and the drive part 310 experience wear, preventing the quick-release base 10 from fully locking the quick-release plate 20. This solution incorporates a self-aligning part 320 to adjust the rotation center of the drive part 310 further away from the clamping part 210. This means the quick-release base 10 can compensate for the wear of the drive part 310 through the adjustment of the self-aligning part 320, thus better releasing the quick-release plate 10. Compared to a quick-release base 10 without a self-aligning part 320, the quick-release base 10 in this solution significantly extends its service life due to the inclusion of the self-aligning part 320.

[0084] Fourth embodiment of quick-release mount

[0085] The quick-release plate 10 in this embodiment has the same basic structure as the quick-release plate 10 in the first embodiment. The locking part 220 is also triggered by a single button to complete the flipping and moving actions to lock the quick-release plate 20. The difference lies in the way the self-aligning part 320 adjusts the rotation center of the drive part 310 closer to the clamping part 210. (Refer to reference...) Figure 2 and Figure 10 In this embodiment, the self-aligning shaft 321 in the self-aligning part 320 is replaced by a guide structure 323 fixed relative to the seat body, and an adjusting member 324 is added to the self-aligning part 320 to adjust the movement of the adjusting member 322 closer to the clamping part 210. Specifically, the self-aligning part 320 includes a guide structure 323, a linkage member 322, and an adjusting member 324. The guide structure 323 is fixed relative to the seat body 100, the linkage member 322 is disposed between the guide shaft 323 and the driving part 310, and the adjusting member 324 is movable relative to the seat body 100 to drive the linkage member 322 to slide along the guide structure 323, thereby driving the driving part 310 closer to the clamping part. Figure 10The diagram illustrates that the linkage 322 is sleeved on the guide structure 323, and the drive unit 310 is sleeved on the linkage 322, thus making the overall structure of the drive assembly more compact. It is understood that in other embodiments, when structural compactness is not a concern, the drive unit 310, linkage 322, and guide structure 323 can be arranged in a non-sleeving manner. The guide structure 323 is axially inclined to the direction of movement of the locking part 220, and its two ends are housed within the mounting cavity 111. The linkage 322, under the action of the adjusting member 324, can slide along the guide structure 323. During the movement of the linkage 322, it can simultaneously drive the drive unit 310 closer to the clamping part 210, so that when the locking part 220 contacts the drive unit 210, it can be driven by the drive unit 210 to move closer to the clamping part 210, compensating for the mass wear of the drive unit 210 and allowing the quick-release seat 10 to completely lock the quick-release plate 20. It should be noted that the implementation of the guide structure 323 is not limited. It can be in the form of a guide shaft / rod in this embodiment, or in the form of a guide space in other embodiments, as long as the linkage 322 can slide along the guide structure 322.

[0086] Continue to refer to Figure 10 The adjusting member 324 includes a threaded member 324a, which is threaded through the base 100 and its end abuts against the linkage member 322. Specifically, the threaded member 324a is inserted into the base 100 along a direction perpendicular to the movement of the locking part 220 and can rotate relative to the base 100. The rotation of the threaded member 324a can drive the linkage member 322 to slide along the guide structure 323. At this time, the linkage member 322 can move towards the side where the clamping part 210 is located, thereby driving the driving part 310 to move closer to the clamping part 220, making the locking part 220 closer to the clamping part 210, reducing the clamping space, increasing the clamping force, and locking the quick-release plate 20. It should be noted that the connection position of the threaded member 324a is not limited. The threaded member 324a can be inserted into the cover plate 120 and abut against the linkage member, or it can be inserted into the base 110 and abut against the linkage member 321. In other embodiments of this application, the adjusting member 324 is also provided with a reset member, which is disposed between the linkage member 32 and the seat 100. When the threaded member 324a rotates out of the linkage member 322, the threaded member 324a cannot provide driving force to the linkage member. At this time, the reset member can release the reset force to drive the linkage member 322 closer to the clamping part 210, thereby driving the driving part 310 closer to the clamping part 220, so that the locking part 220 is closer to the clamping part 210, reducing the clamping space and increasing the clamping force to lock the quick-release plate 20.

[0087] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
