Background

With the extreme pursuit of the user for the use experience, the shooting quality requirement of the user for the image pickup apparatus is also higher and higher. A pan/tilt head has attracted attention from users as a device capable of providing functions such as stability enhancement and anti-shake for an image pickup apparatus (e.g., a mobile phone).

In practical applications, in order to obtain a more stable shot picture, especially to enhance the stability of the camera device on the pan/tilt head in a motion mode, the pan/tilt head and the camera device are usually connected through a multi-axis stabilizer. For example, the existing triaxial stabilizer provides angle compensation of three rotation angles for the image pickup apparatus through three rotation motors, so that a picture photographed by the image pickup apparatus in a motion mode is also more stable. However, in some special scenarios, for example, when the camera device is fixedly stored together with the pan/tilt head, multiple degrees of freedom of the multi-axis stabilizer need to be constrained and locked to improve the rigidity and the load capacity of the stabilizer. In the prior art, a locking mechanism is usually provided for each shaft of a multi-shaft stabilizer, so that each degree of freedom of the multi-shaft stabilizer is locked by the locking mechanism.

In this embodiment, the locking mechanism is used to connect the first device main body and the second device main body, the specific first device main body may be a cradle head, and the like, and the second device main body may be a camera, a camera lens, and the like.

In practical applications, when a camera is mounted on a pan/tilt head, in order to obtain a more stable shot, especially to enhance the stability of the camera on the pan/tilt head in a motion mode, the pan/tilt head and the camera are usually connected by a multi-axis stabilizer. However, in some special scenarios, for example, in order to facilitate storage and to improve the load capacity, it is necessary to increase the stiffness of the multi-axis stabilizer by constraining and fixing multiple degrees of freedom of the multi-axis stabilizer. Based on this, this application embodiment provides a locking mechanical system, and this locking mechanical system can realize the injecing to a plurality of degrees of freedom of camera through a key, is equivalent to injecing each axle degree of freedom of multiaxis stabilizer, has promoted connection stability and joint strength between each axle, makes the locking of user to the camera or each axle degree of freedom of multiaxis stabilizer more convenient and fast.

Referring to fig. 1, a schematic structural diagram of a locking mechanism according to an embodiment of the present application is shown. Referring to fig. 2, a cross-sectional structural view of the locking mechanism of fig. 1 is shown.

In the embodiment of the present application, the locking mechanism 3 may specifically include: the base 10 is used for connecting the cloud deck, and the base 10 is provided with an accommodating groove 101 and a sliding groove 102 communicated with the accommodating groove 101; the first connecting piece 20 comprises a connecting rod 201 and a ball shaft 202 arranged at one end of the connecting rod 201, the ball shaft 202 is movably arranged in the accommodating groove 101, and the other end of the connecting rod 201 extends out of the notch of the accommodating groove 101 to be connected with the camera device 2; the locking piece 30 is arranged in the accommodating groove 101, and the locking piece 30 is at least partially arranged around the ball shaft 202; the sliding member 40, the sliding member 40 is partially slidably disposed in the sliding groove 102, and one end of the sliding member 40 is opposite to the ball axle 202, the sliding member 40 slides along the sliding groove 102, and pushes the ball axle 202 to be locked on the locking member 30 or to be disengaged and unlocked from the locking member 30.

In the embodiment of the present application, since the connecting rod 201 of the first connecting member 20 can be connected to the camera device 2, and the base 10 is used for connecting the pan/tilt head 1, in practical applications, the locking mechanism 3 can be used for connecting between the pan/tilt head 1 and the camera device 2.

In the embodiment of the present application, the image capturing device 2 may include, but is not limited to, any one or more of a camera, a lens, a gun camera, a dome camera, an all-in-one camera, an infrared day and night camera, a high speed dome camera, a web camera, and the like.

In the embodiment of the present application, since the ball shaft 202 is movably disposed in the receiving groove 101, when the sliding component 40 does not push the ball shaft 202 to be locked to the locking member 30, or when the ball shaft 202 is separated from and unlocked from the locking member 30, the camera device 2 at the other end of the connecting rod 201 can be adjusted by the ball shaft 202 with multiple directional degrees of freedom, and has multiple axial degrees of freedom; in the case where the slide member 40 pushes the ball shaft 202 to be locked to the locking member 30, or after the ball shaft 202 is locked to the locking member 30, it is equivalent to simultaneously locking the multiple-axis degrees of freedom of the image pickup device 2. In the embodiment of the present application, the locking of the multi-axis degrees of freedom of the camera device 2 is achieved by pushing the ball shaft 202 to lock on the locking member 30 through the sliding member 40, which is simple and convenient, and the overall stability and the connection strength of the camera device 2 are improved, thereby avoiding the problem of poor stability and connection strength between the multi-axis of the multi-axis stabilizer caused by separately locking each degree of freedom.

In the embodiment of the present application, when the ball shaft 202 is in the unlocked state, the posture of the imaging device 2 on the pan/tilt head 1 can be freely adjusted by rotating the ball shaft 202 in the accommodation groove 101. In addition, by the movable arrangement of the ball shaft 202 in the accommodation groove 101, the confusion of various positions caused by various machining tolerances and assembly tolerances when the camera device 2 is connected to the pan/tilt head 1 can be eliminated. After the attitude, angle, etc. of the image pickup device 2 are adjusted, the ball shaft 202 is pushed by the slide member 40 to lock the ball shaft 202 to the lock member 30, so that the image pickup device 2 can be locked in the current state by the above-described lock mechanism.

In the embodiment of the present application, the ball axle 202 is locked to the locking member 30 by pushing the sliding member 40 to abut against the locking member 30.

In the embodiment of the present application, there are various ways to lock the ball axle 202 in the receiving groove 101. In one implementation manner of the embodiment of the present application, an annular groove 1011 is formed on an inner wall of the accommodating groove 101, which is close to the notch; the locking piece 30 is an elastic clamping piece, the elastic clamping piece is partially embedded in the annular groove 1011, and the inner diameter of the elastic clamping piece is smaller than the outer diameter of the ball shaft 202; under the condition that the ball axle 202 is in the locking state, the ball axle 202 is clamped on the elastic clamping piece, and under the condition that the ball axle 202 is in the unlocking state, the clamping of the ball axle 202 and the elastic clamping piece is released.

In the embodiment of the present application, the notch of the receiving groove 101 can be larger than the outer diameter of the ball axle 202, so that the ball axle 202 can be conveniently mounted in the receiving groove 101. In order to avoid the ball axle 202 from coming out of the receiving groove 101, the elastic clamping piece can be embedded in the annular groove 1011 on the inner wall of the receiving groove 101, and the inner diameter of the elastic clamping piece is smaller than the outer diameter of the ball axle 202. Thus, the ball axle 202 can be movably disposed in the accommodating groove 101, and the ball axle 202 is prevented from being disengaged from the accommodating groove 101. In some embodiments, the annular groove 1011 is disposed on the inner wall of the receiving groove 101 near the notch.

In practice, the slide assembly 40 may move closer to or further away from the ball axle 202 as the slide assembly 40 slides along the slide channel 102. Specifically, when the sliding assembly 40 slides in the direction close to the ball axle 202, one end of the sliding assembly 40 abuts against the ball axle 202 to push the ball axle 202 to abut against the elastic clamping member, so that the ball axle 202 can be locked, or when the sliding assembly 40 slides in the direction away from the ball axle 202, one end of the sliding assembly 40 releases the abutment against the ball axle 202, so that the ball axle 202 can be separated from the elastic clamping member and unlocked.

Optionally, the elastic clamping piece may be a clamping spring.

In the embodiment of the application, the clamp spring is wide in application range, low in cost and simple in structure, so that the clamp spring is simpler to mount in the annular groove 1011, and lower in implementation cost. In practical application, the clamp spring can be connected in an interference fit manner in the annular groove 1011.

It can be understood that, in the embodiment of the present application, the receiving groove 101 may also be configured to be a necking arrangement, that is, the size of the notch of the receiving groove 101 is smaller than the outer diameter of the ball axle 202, so that the ball axle 202 can also be movably disposed in the receiving groove 101. When the sliding assembly 40 slides along the sliding groove 102, the ball axle 202 can be close to the ball axle 202 and abut against the inner wall of the receiving groove 101 close to the notch to lock the ball axle 202, or the ball axle 202 can be far away from the ball axle 202 to disengage the ball axle 202 from the inner wall of the receiving groove 101 to unlock the ball axle 202. Thus, the number of components is reduced by reducing the number of the locking member 30.

Optionally, a through hole 103 connected to the sliding groove 102 is formed at the bottom of the receiving groove 101, and one end of the sliding assembly 40 extends into the receiving groove 101 through the through hole 103 and is opposite to the ball axle 202.

In the embodiment of the present application, the through hole 103 connected to the sliding groove 102 is disposed at the bottom of the accommodating groove 101, so that the sliding assembly 40 partially extends into the accommodating groove 101 through the through hole 103 to abut against the ball shaft 202, and the ball shaft 202 is pushed and locked on the locking member 30, or the sliding assembly 40 retracts into the sliding groove 102, and then the abutting of the sliding assembly 40 against the ball shaft 202 is released, and the ball shaft 202 is separated from the locking member 30 and unlocked.

As shown in fig. 2, the sliding assembly 40 may specifically include: a first slider 41 and a second slider 42; the first slide block 41 and the second slide block 42 are movably arranged in the slide groove 102; one end of the first slider 41 is opposite to one end of the second slider 42, the other end of the second slider 42 extends into the receiving groove 101 through the through hole 103 and is opposite to the ball shaft 202, and the second slider 42 is pushed by the first slider 41 to abut against the ball shaft 202 to lock the ball shaft 202 on the locking member 30, or the abutment of the ball shaft 202 is released to separate and unlock the ball shaft 202 from the locking member 30.

In the embodiment of the present application, the moving directions of the first slider 41 and the second slider 42 may be the same or different. It can be understood that when the moving directions of the second slider 42 and the first slider 41 are the same, i.e. moving toward the ball axle 202 or moving away from the ball axle 202, the second slider 42 and the first slider 41 can be combined into a single slider, which can save the number of parts, reduce the material cost of the sliding assembly 40, and reduce the assembly cost. Since the structure of the second slider 42 moving in the same direction as the first slider 41 is relatively simple, the description of the embodiment of the present application is omitted.

In the embodiment of the present application, a specific implementation of the locking mechanism 3 will be explained by taking the example that the moving directions of the first slider 41 and the second slider 42 are different.

In the embodiment of the present application, the moving direction of the first slider 41 is perpendicular to the moving direction of the second slider 42, a first inclined plane is disposed at one end of the first slider 41, a second inclined plane is disposed at one end of the second slider 42, and the first inclined plane abuts against the second inclined plane. Specifically, the sliding direction of the first slider 41 in the sliding groove 102 may be a first direction, i.e., a direction, and the sliding direction of the second slider 42 in the sliding groove 102 may be a second direction, i.e., a direction B, where the first direction is perpendicular to the second direction. In the embodiment of the present application, the first direction may be understood as a left-right direction in fig. 2, and the second direction may be understood as an up-down direction in fig. 2. When the first slider 41 slides in the sliding groove 102 in the first direction toward the direction close to the second slider 42 (i.e. slides rightward), because the first inclined surface abuts against the second inclined surface, the first slider 41 can push the second slider 42 to move downward along the first inclined surface, so that the first slider 41 can push the second slider 42 to abut against the ball axle 202, and further push the ball axle 202 to lock on the locking member 30; when the first slider 41 slides in the sliding groove 102 in the first direction toward the direction away from the second slider 42 (i.e., leftward sliding), that is, the second slider 42 can move upward along the first inclined plane, the second slider 42 can release the contact with the ball axle 202, so that the ball axle 202 is disengaged from the locking member 30 and unlocked. In the embodiment of the present application, the first inclined surface of the first slider 41 abuts against the second inclined surface of the second slider 42, so that the movement of the first slider 41 along the first direction is converted into the movement of the second slider 42 along the second direction, and the structure of the locking mechanism 3 is more flexible and more compact.

In some alternative embodiments, the sliding assembly 40 may further include: a slide shaft 43; the sliding shaft 43 is arranged in the sliding groove 102 and fixedly connected with the base 10; the first sliding block 41 is slidably sleeved on the sliding shaft 43, so as to regulate the sliding path of the first sliding block 41 through the sliding shaft 43, thereby preventing the first sliding block 41 from shaking in the sliding groove 102, and making the sliding of the first sliding block 41 in the sliding groove 102 more stable.

In practical applications, in order to facilitate the user to lock or unlock the ball axle 202, the sliding assembly 40 may further include: a lock button 44; the locking button 44 is movably sleeved on the sliding shaft 43, one end of the locking button 44 is opposite to the other end of the first sliding block 41, and the other end of the locking button 44 extends out of the sliding groove 102; with the locking button 44 in the first position of the sliding shaft 43, the first slider 41 pushes the second slider 42 against the ball axle 202 to lock the ball axle 202 to the locking member 30; when the lock button 44 is at the second position of the slide shaft 43, the first slider 41 releases the contact with the second slider 42, and the ball shaft 202 is disengaged from the lock member 30 and unlocked.

In the embodiment of the present application, the other end of the locking button 44 protrudes out of the sliding groove 102 to facilitate manual operation. Specifically, a first rotation portion 441 may be provided at an end of the lock button 44 protruding out of the slide groove 102, so that a human hand can operate the lock button 44 by the first rotation portion 441. In the embodiment of the present application, through the sliding of the locking button 44 on the sliding groove 102, one-key locking of the ball axle 202 can be realized, that is, through the locking of the ball axle 202, thereby locking four degrees of freedom of the camera device 2 on the pan-tilt, avoiding the problem that when each degree of freedom of the multi-axis stabilizer is locked separately, the use of multiple shaft locks is complicated independently (each shaft of the multi-axis stabilizer is correspondingly provided with a locking mechanism, which is referred to as shaft lock for short) and improving the connection stability and the connection strength between the shafts of the multi-axis stabilizer.

In the embodiment of the present application, the first position and the second position may be provided at intervals on the sliding shaft 43 in the length direction of the sliding shaft 43, or may also be provided at intervals on the sliding shaft 43 in the circumferential direction of the sliding shaft 43.

In the embodiment of the present application, the locking button 44 and the sliding shaft 43 may be connected by a screw or a snap. For example, the sliding shaft 43 is provided with an external thread, the locking button 44 is provided with an internal thread, and the internal thread and the external thread are meshed and connected, so that when the ball shaft 202 needs to be locked, the locking button 44 can rotate towards the sliding groove 102, the locking button 44 pushes the first slider 41, the first slider 41 pushes the second slider 42, the second slider 42 abuts against the ball shaft 202, and the ball shaft 202 is pushed to be clamped on the clamp spring to lock the ball shaft 202; when the ball shaft 202 needs to be unlocked, the lock button 44 is turned outward of the slide groove 102, so that the lock button 44 releases the pushing of the first slider 41, the first slider 41 releases the contact with the second slider 42, the second slider 42 is disengaged from the ball shaft 202, and the ball shaft 202 is disengaged from the snap spring and unlocked.

In the embodiment of the present application, in order to make the ball axle 202 more stable in the receiving groove 101, the locking mechanism 3 may further include: an elastic member 50; the elastic element 50 is movably sleeved on the second slider 42 and located at one end of the receiving groove 101, one end of the elastic element 50 abuts against the bottom of the receiving groove 101, and the other end abuts against the ball axle 202.

In the embodiment of the present application, the elastic member 50 elastically abuts against the ball axle 202, so that the ball axle 202 can be stably located in the accommodating groove 101 in both the locked state and the unlocked state. In the case where the ball shaft 202 is in the unlocked state, the ball shaft 202 can be stably rotated in the receiving groove 101 with four degrees of freedom due to the abutment of the elastic member 50, and when the ball shaft 202 is changed from the locked state to the unlocked state, since the second slider 42 is changed from the abutment of the ball shaft 202 to the release of the abutment of the ball shaft 202, that is, the second slider 42 slides in a direction away from the ball shaft 202, and the ball shaft 202 is also subjected to the elastic force in the direction away from the second slider 42 by the elastic member 50, the second slider 42 can be easily released from the abutment of the ball shaft 202, and therefore, in the present embodiment, the elastic member 50 can be understood as being used to drive the ball shaft 202 to be disengaged from the locking member 30 and unlocked in the case where the second slider 42 releases the abutment of the ball shaft 202.

In practical applications, the elastic member 50 may be a spring, a leaf spring, or the like.

In the embodiment of the present application, the connecting rod 201 and the ball axle 202 may be formed as an integral structure, so that the connection between the connecting rod 201 and the ball axle 202 is more reliable. Alternatively, the connecting rod 201 and the ball axle 202 can be detachably connected, so as to increase the processing difficulty of the connecting rod 201 and the ball axle 202. For example, the ball axle 202 can be used as the connecting rod 201 by providing a threaded hole on the ball-shaped member and inserting a bolt through the threaded hole, which can simplify the connection between the connecting rod 201 and the ball axle 202 and reduce the cost of the ball axle 202 and the connecting rod 201.

In practical applications, the connecting rod 201 may be directly connected to the image capturing device 2, or may be connected to the image capturing device 2 through an intermediate member. Optionally, the locking mechanism 3 may further include: a second connecting member 60; one end of the connecting rod 201 is connected with the image pickup device 2 through the second connecting member 60, so that the connection between the connecting rod 201 and the image pickup device 2 is more reliable through the second connecting member 60.

In the embodiment of the present application, the second connecting member 60 can be used as a component connected to the image capturing device 2, and can also be used as a knob, so that the connection between the second connecting member 60 and the image capturing device 2 is simpler. Specifically, one end of the second connecting member 60 is provided with a second rotating portion 601, and the other end is provided with a second connecting portion 602 for connecting the camera device 2; the second rotating portion 601 is sleeved on the other end of the connecting rod 201 and is fixedly connected with the connecting rod 201.
