DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, an embodiment of the present invention provides a quick-release connection assembly including a first connector 10, a second connector 11, a snap 12, and a locking mechanism 13;

the first connector 10 is provided with a clamping part 101, the second connector 11 is provided with a containing part 111 and a containing part 112 which are mutually communicated, the containing part 111 is used for containing the clamping part 101, and the clamping part 101 can be inserted into the containing part 111 along a first direction;

the engaging member 12 is at least partially accommodated in the accommodating portion 112 and is slidable in a second direction in the accommodating portion 112, the second direction being different from the first direction;

the locking mechanism 13 can drive the clamping piece 12 to move and is used for locking the clamping piece 12;

when the clamping portion 101 is inserted into the accommodating portion 111, the locking mechanism 13 may drive the clamping member 12 to approach the clamping portion 101 until the clamping member 12 and the clamping portion 101 are clamped, so that the first connecting member 10 and the second connecting member 11 are detachably connected together.

Specifically, as shown in fig. 1, the embodiment of the invention provides a quick-dismantling connection assembly capable of being dismantled quickly, which can be used in products requiring frequent disassembly, such as a battery and a battery holder, a remote controller and a device to be remote controlled, a cradle head device and a cradle head base, and the like. In the embodiment of the present invention, the quick-release connection assembly may include a first connector 10, a second connector 11, a clamping member 12, and a locking mechanism 13.

The first connector 10 and the second connector 11 may be two separate parts, and in different usage scenarios, the first connector 10 and the second connector 11 may need to be connected and assembled together, and the first connector 10 and the second connector 11 may need to be detached and used separately. For example, when the first connector 10 is part of a battery handle and the second connector 11 is part of a main battery holder, the first connector 10 and the second connector 11 need to be connected and assembled together in a use state, and the first connector 10 and the second connector 11 need to be detached and separated in a charged state. The engaging member 12 is a member that can be used to secure the two components together when they are assembled together. Specifically, the first connector 10 is provided with a clamping portion 101, the second connector 11 may be a part of a shell structure, the second connector 11 is provided with a containing portion 111 and a containing portion 112 which are mutually communicated, the clamping member 12 is slidably connected with the containing portion 112, the containing portion 111 is used for containing the clamping portion 101, the clamping portion 101 can be inserted into the containing portion 111 along the first direction +z direction, and the clamping member 12 can slide to a deeper position or a shallower position in the containing portion 112 when sliding along the second direction +y direction in the containing portion 112. When the clamping portion 101 of the first connector 10 is embedded in the accommodating portion 111, the clamping member 12 moves to a deeper position in the accommodating portion 112, and can approach the clamping portion 101 to clamp and fix the first connector 10. The locking mechanism 13 is linked with the engaging member 12, and when the locking mechanism 13 moves, the engaging member 12 can be driven to move. When the clamping portion 101 is inserted into the accommodating portion 111, the locking mechanism 13 can drive the clamping member 12 to approach the clamping portion 101 until the clamping member 12 is clamped with the clamping portion 101, so as to detachably connect the first connecting member 10 and the second connecting member 11 together. When the first connecting piece 10 and the second connecting piece 11 need to be detached and separated, the locking mechanism 13 drives the clamping piece 12 to move reversely.

It should be noted that, the clamping portion 101 may be provided with a clamping groove, which may be continuous or discontinuous, and when the clamping groove is in a discontinuous structure, the clamping groove may be regarded as a plurality of blind holes separately provided. Correspondingly, a clamping protrusion can be arranged on the clamping piece 12, when the clamping groove is continuous, the clamping protrusion corresponds to a strip-shaped continuous protrusion with the same length, and the shape of the protrusion is matched with that of the clamping groove. When the clamping groove is discontinuous, the clamping protrusion corresponds to a plurality of separated protrusions, for example, when the clamping groove is of a plurality of dispersed blind hole structures, the clamping protrusion can be a convex column corresponding to the blind hole, and the convex column can be inserted into the blind hole. Thus, the relative movement of the first connector 10 and the second connector 11 can be restricted by the engagement of the engaging protrusion and the engaging groove.

Alternatively, referring to fig. 1, the locking mechanism 13 is mounted on the second link 11, and the locking mechanism 13 may be selectively in a locked state or an unlocked state;

when the locking mechanism 13 is in the locked state, the locking mechanism 13 drives the clamping piece 13 to approach the clamping portion 101 so that the clamping piece 12 is clamped with the clamping portion 101;

when the locking mechanism 13 is in the unlocked state, the locking mechanism 13 drives the engaging piece 13 away from the engaging portion 101 so as to separate the engaging piece 12 from the engaging portion 101.

Specifically, as shown in fig. 1, in one embodiment, the locking mechanism 13 may be mounted on the second connector 11, and the locking mechanism 13 and the second connector 11 may move relatively, and when the locking mechanism 13 moves to different positions, the locking mechanism is in a locked state or an unlocked state, respectively.

When the locking mechanism 13 is in a locking state, at this time, the locking mechanism 13 moves relative to the second connecting piece 11, so that the locking piece 12 can be driven to approach the locking portion 101, the locking piece 12 moves to a deeper position in the accommodating portion 112 in a sliding manner, after the locking piece 12 contacts with the locking portion 101, under the action of friction force or under the cooperation of the locking groove and the locking protrusion, the locking connection between the locking piece 12 and the locking portion 101 is realized, and therefore, the first connecting piece 10 and the second connecting piece 11 are locked together.

When the locking mechanism 13 is in the unlocked state, at this time, the locking mechanism 13 moves relative to the second connector 11, so that the engaging member 12 can be driven to be away from the engaging portion 101, and the engaging member 12 can slide to a shallower position in the accommodating portion 112, and can be separated from the engaging portion 101, so that the first connector 10 can be released.

Alternatively, referring to fig. 1, the locking mechanism 13 includes an operating member 131, the operating member 131 being mounted on the second link 11 and slidable in a third direction with respect to the second link 11;

one end of the operating member 131 is movably connected with the engaging member 12, wherein when the operating member 131 slides along the third direction, the engaging member 12 can be driven to slide along the second direction.

Specifically, as shown in fig. 1, in one embodiment, the locking mechanism 13 may include an operating member 131, where the operating member 131 is mounted on the second connecting member 11 and is slidable in a third direction relative to the second connecting member 11. For example, the operating member 131 may slide in the ±x directions shown in fig. 1. When the operating member 131 moves relative to the second connecting member 11, at the same time, since one end of the operating member 131 is movably connected with the engaging member 12, the engaging member 12 can be driven to displace in a second direction different from the third direction, and in combination with the illustration of fig. 1, the engaging member 12 can be driven to slide in the second direction ±y direction. When the operating member 131 drives the engaging member 12 to slide along the +y direction, the engaging member 12 is separated from the second connecting member 11; when the operating member 131 drives the engaging member 12 to slide along the-Y direction, the engaging member 12 engages with the second connecting member 11.

It should be noted that, the third direction is the movement direction of the operating member 131 relative to the second connecting member 11, the second direction is the movement direction of the engaging member 12 relative to the second connecting member 11, and the first direction is the movement direction of the first connecting member 10 relative to the second connecting member 11. At least two of the three movement directions are different, so that the reasonability of the structural layout is considered while the linkage movement is realized, and the structural interference and conflict can be avoided.

Alternatively, referring to fig. 1, the second connecting member 11 is provided with a shaft hole 113, and the operating member 131 is a transmission shaft penetrating the shaft hole 113.

Specifically, as shown in fig. 1, in one embodiment, the second connector 11 is provided with a shaft hole 113, and it is understood that the axis of the shaft hole 113 is along the aforementioned third direction, so that the shaft as the operating member 131 can slide along the third direction when the transmission shaft is inserted into the shaft hole 113. In a specific implementation, the shaft hole 113 may also be communicated with the accommodating portion 112, so that when the transmission shaft is inserted into the shaft hole 113, one end of the transmission shaft, which is close to the bottom of the shaft hole 113, can be movably connected with the engaging member 12, so as to implement that the operating member 131 drives the engaging member 12 to move.

Optionally, referring to fig. 1 and 2, the locking mechanism 13 further includes a linkage member 132, and the operating member 131 drives the engaging member 12 through the linkage member 132.

Specifically, as shown in fig. 1 and 2, in one embodiment, the locking mechanism 13 further includes a linkage 132, where the linkage 132 is used to connect the locking mechanism 13 with the engaging member 12, so as to implement motion transmission. When the operation member 131 moves, the linkage member 132 is driven to move synchronously, and the movement of the linkage member 132 drives the engaging member 12. Illustratively, the linkage 132 may be a pin that is fixedly coupled to the drive shaft while the pin is also movably coupled to the engaging member 12. In an embodiment, as shown in fig. 1, an end of the operating member 131 near the bottom of the shaft hole 113 may be fixedly connected to the linkage member 132, for example, by fastening a pin to a transmission shaft by screw connection. The engaging member 12 is provided with a first slide groove 121, and the linking member 132 is inserted into the first slide groove 121 and is slidable in the first slide groove 121. Thus, when the transmission shaft moves under axial force, the pin is driven to move synchronously, and the pin enables the clamping piece 12 to move.

Optionally, the engaging member 12 is fixedly connected with the linking member 132, the operating member 131 is provided with a first sliding groove, and the linking member 132 is inserted into and slidable in the first sliding groove.

Specifically, in one embodiment, the first sliding groove may be further formed on the operating member 131, and correspondingly, in this solution, the linkage member 132 and the engaging member 12 are fixedly connected together, and the linkage member 132 is inserted into the first sliding groove and is slidable in the first sliding groove, so that the operating member 131 may also be utilized to drive the engaging member 12 to move. When the fixed connection between the operating member 131 and the linkage member 132 is difficult to realize, the movement of the engaging member 12 can be realized by adopting the connection mode of the scheme.

Alternatively, referring to fig. 1 or 2, the extending direction of the first chute 121 obliquely intersects with the third direction.

Specifically, as shown in fig. 1 or 2, in one embodiment, the extending direction of the first chute 121 obliquely intersects with the third direction. That is, for the assembled quick release connection assembly, the extending direction of the first sliding groove 121 forms a predetermined angle with the ± X direction, so that when the operating member 131 moves along the third direction, a component force is formed in the sliding direction (i.e. the second direction) of the engaging member 12, so as to form a driving force for sliding the engaging member 12.

Optionally, referring to fig. 1, the locking mechanism 13 further includes an elastic member 133, where the elastic member 133 is configured to provide a restoring force to the operating member 131, so that the transmission shaft can be automatically reset after moving along the third direction.

Specifically, as shown in fig. 1, in one embodiment, the locking mechanism 13 may further include an elastic member 133, where the elastic member 133 is configured to provide a restoring force for restoring the operating member 131 to the initial position. For example, as for the transmission shaft, when the transmission shaft moves in the +x direction after being axially pressed, the transmission shaft can move in the-X direction to automatically return to the pre-pressing position by the elastic force of the elastic member 133 when the pressing force is removed.

It is understood that the elastic member 133 may be a compression elastic member or a tension elastic member. Such as a compression spring or an extension spring. The elastic member 133 may be installed and fixed between the operating member 131 and the second connecting member 11, where the second connecting member 11 is a stationary structure, and elastic force generated by elastic deformation of the elastic member 133 acts on the movable operating member 131, so that the operating member 131 automatically resets.

For example, the elastic member 133 may abut against one end of the operating member 131 away from the engaging member 12, and the other end abuts against the second connecting member 11. For example, a compression spring is placed at the bottom of the shaft hole 113, one end of the compression spring is abutted against the bottom surface of the shaft hole 113, and the other end of the compression spring is abutted against the end of the operating element 131. Thus, when the compression spring is in a compressed state, the elastic force of the compression spring acts on the operation piece 131, so that the operation piece 131 has a movement tendency to be automatically reset from the shaft hole 113. It will be appreciated that an extension spring may be installed between the operating member 131 and the second connecting member 11, in which case, the operating member 131 may be automatically reset by the tension of the spring, and when the extension spring is used as the elastic member 133, the operating member 131 is engaged with the first connecting member 10 to maintain the locked state when the operating member 131 is pulled by the user operation, and the driving engaging member 12 is separated from the first connecting member 10 to be in the unlocked state.

In addition, instead of installing the fixing elastic member 133 in the above manner, the elastic member 133 may be sleeved on the operation member 131. For example, a compression spring is sleeved on the transmission shaft, one end of the compression spring is restrained and positioned through the bottom surface of the shaft hole 113, and the other end of the compression spring is restrained and positioned through a shaft shoulder of the transmission shaft. If the elastic member 133 is a tension spring, when the tension spring is sleeved on the transmission shaft, both ends of the tension spring may be fixedly connected to the operating member 131 and the second connecting member 11 by screws, respectively.

Optionally, referring to fig. 1, the second connecting piece 11 is provided with a second sliding groove 114, the second sliding groove 114 is communicated with the shaft hole 113, and the length direction of the second sliding groove 114 is parallel to the axis of the shaft hole 113.

Specifically, as shown in fig. 1, in one embodiment, the second connecting member 11 is provided with a second chute 114, the second chute 114 penetrates through the shaft hole 113, and the length direction of the second chute 114 is parallel to the axis of the shaft hole 113. In connection with the illustration, it will be readily understood that the opening of the second runner 114 and the opening of the shaft hole 113 are located on two different surfaces of the second connecting member 11, as illustrated in fig. 2, the opening of the second runner 114 is located on the upper surface of the second connecting member 11, and the opening of the shaft hole 113 is located on the side surface of the second connecting member 11. The second runner 114 can provide a designed travel for the linkage 132 and the operating member 131.

Optionally, referring to fig. 1, the engaging member 12 includes a locking portion 122 and a connecting portion 123 that are integrally connected, the connecting portion 123 is provided with a bar-shaped through hole 1231 and the second chute 121, the bar-shaped through hole 1231 is communicated with the second chute 121, and an axis of the bar-shaped through hole 1231 and a length direction of the second chute 121 are obliquely arranged to form a preset included angle.

Specifically, as shown in fig. 1, in one embodiment, the locking member 12 includes a locking portion 122 and a connecting portion 123 that are integrally connected, the locking portion 122 is used for fixing the locking portion 101 in a locking manner, the locking portion 101 may be provided with a groove along the ± X direction in the drawing, and the locking portion 122 may be provided with a protrusion matching the shape of the groove along the ± X direction. When the engaging member 12 approaches the first connecting member 10, the protrusion is embedded into the groove, so as to limit the movement of the first connecting member 10 in the ±z directions and prevent the first connecting member 10 from falling off. When the engaging member 12 is far away from the first connecting member 10, the protrusion is separated from the groove, and the first connecting member 10 can move along the ±z direction and be withdrawn from the accommodating portion 111.

The connecting portion 123 is inserted into the accommodating portion 112, and moves in the illustrated Y direction in the accommodating portion 112 to realize a sliding connection. The connecting portion 123 is provided with a bar-shaped through hole 1231 and a first chute 121, the cross section of the bar-shaped through hole 1231 is long and has a sufficient design length, so that the locking member 12 has a pre-designed movement stroke when sliding in the accommodating portion 112, and is not blocked, the axis of the bar-shaped through hole 1231 is perpendicular to the sliding direction of the locking member 12 in the accommodating portion 112, for example, in combination with the illustration, the sliding direction of the locking member 12 in the accommodating portion 112 is ±y direction, and the axis of the bar-shaped through hole 1231 is ±x direction. The first sliding groove 121 is communicated with the bar-shaped through hole 1231, and the axis of the first sliding groove 121 is perpendicular to the axis of the bar-shaped through hole 1231 and the sliding direction of the engaging member 12, for example, in combination with the illustration, the axis of the first sliding groove 121 may be in the ±z direction. Also, the axis of the bar-shaped through hole 1231 is obliquely arranged with the length direction of the first chute 121 to form a preset angle, which may be 45 degrees, for example. The inclined arrangement ensures that a driving force is generated in the Y direction of the engaging member 12 to drive the engaging member 12 to move back and forth in the Y direction within the accommodating portion 112.

Alternatively, referring to fig. 1 or 3, the compression spring is embedded in the bottom of the shaft hole 113, the operating member 131 is simultaneously inserted into the bar-shaped through hole 1231 and the shaft hole 113, one end of the compression spring abuts against the bottom of the shaft hole 113, and the other end of the compression spring abuts against the end of the operating member 131.

Specifically, as shown in fig. 1 or 3, in one embodiment, when the compression spring is used as the elastic member 133, the compression spring may be fitted to the bottom of the shaft hole 113, the bar-shaped through hole 1231 may be aligned with the shaft hole 113 after the engaging member 12 is inserted into the accommodating portion 112, the operation member 131 may be inserted into the shaft hole 113 while passing through the bar-shaped through hole 1231 until the compression spring is pressed, and at this time, one end of the compression spring abuts against the bottom surface of the shaft hole 113, and the other end of the compression spring abuts against the end of the operation member 131. Thus, when the compression spring is in a compressed state, the elastic force of the compression spring acts on the operation piece 131, so that the operation piece 131 has a movement tendency to be automatically reset from the shaft hole 113.

Alternatively, referring to fig. 1 or 3, the linkage member 133 passes through both the first chute 121 and the second chute 114, and the linkage member 133 is fixedly connected to the operation member 131.

Specifically, as shown in fig. 1 or fig. 3, in one embodiment, the linkage member 132 may pass through the first chute 121 and the second chute 114 at the same time, and the linkage member 132 and the operation member 131 are fixedly connected by a clamping or threaded connection. As can be understood from the illustration of fig. 3, when the elastic force of the elastic member 133 acts on the operating member 131, since the link member 132 is fixedly connected to the operating member 131 and the movement of the link member 132 is limited by the end of the second chute 114, the operating member 131 is not ejected from the shaft hole 113.

Alternatively, referring to fig. 3, the locking mechanism 13 is nested with the engaging member 12.

Specifically, as shown in fig. 3, in one embodiment, the locking mechanism 13 and the engaging member 12 may be nested together, and the interlocking of the locking mechanism 13 and the engaging member 12 is achieved by using the nesting relationship between the locking mechanism 13 and the engaging member 12, for example, the transmission shaft in the locking mechanism 13 is inserted through the bar-shaped through hole 1231 of the engaging member 12 to achieve the nesting connection between the locking mechanism and the engaging member.

In order to facilitate understanding of the operation principle of the operation member 131, the linkage member 132, and the elastic member 133, the description will be made below with reference to the actual application scenario. For the quick-release connection assembly assembled according to the connection relationship, when the operation member 131 is in a free state, that is, the axial direction is not subjected to external force, the axial direction of the operation member 131 is only subjected to the elastic force of the elastic member 133, the operation member 131 is in the ejecting movement trend, at this time, the extending length of the operation member 131 in the shaft hole 113 is shorter, and at the same time, the linkage member 132 is also at the end in the-X direction in the second sliding groove 114, and because the linkage member 132 also passes through the first sliding groove 121, the corresponding linkage member 132 is also at the end in the-X direction and the Y direction in the first sliding groove 121. That is, when the operating member 131 is in the free state, the engaging member 12 is inserted deeper into the accommodating portion 112, and the engaging portion 101 can clamp the first connecting member 10.

For the quick release connection assembly assembled according to the connection relationship, when the operation member 131 is pressed axially, the operation member 131 is in a movement tendency of being pressed into the shaft hole 113, at this time, the length of the operation member 131 extending into the shaft hole 113 is long, and at the same time, the linkage member 132 is also at the end in the X direction of the second sliding groove 114, and since the linkage member 132 also passes through the first sliding groove 121, the linkage member 132 is correspondingly also at the end in the X direction and the Y direction of the first sliding groove 121. That is, when the operating member 131 is pressed, the axial force applied to the operating member 131 drives the fixed link member 132 to move, and when the link member 132 moves in the first chute 121, the axis of the bar-shaped through hole 1231 forms a predetermined angle with the longitudinal direction of the first chute 121, so that a component force is formed in the sliding direction of the engaging member 12, thereby forming a driving force for sliding the engaging member 12. The driving force causes the engaging member 12 to move outwardly from the accommodating portion 112, the engaging member 12 is inserted shallower into the accommodating portion 112, and the engaging member 12 can release the first connecting member 10. When the external force pressing on the operating member 131 is removed, the operating member 131 automatically pops up under the action of the elastic member 133, and drives the engaging member 12 to automatically reset to clamp the first connecting member 10.

Optionally, referring to fig. 3 to 5, the quick-release connection assembly further includes a limiting assembly 14, where the limiting assembly 14 is connected to the operating member 131 and is used for limiting the position of the operating member 131;

when the limiting assembly 14 is in the limiting state, the limiting assembly 14 prevents the operating member 131 from sliding along the third direction;

when the limiting assembly 14 is in the non-limiting state, the operating member 131 can slide freely along the third direction.

Specifically, as shown in fig. 3 to 5, in one embodiment, in order to prevent the first connector 10 from being separated from the second connector 11 by touching the operating member 131 by mistake, the quick release connection assembly may further include a limiting assembly 14, where the limiting assembly 14 is connected to the operating member 131 and is used for limiting the position of the operating member 131. When the limiting assembly 14 is in the limiting state, the operating member 131 is blocked by the limiting assembly 14, and the operating member 131 cannot slide along the third direction, so that the movement of the engaging member 12 cannot be driven, and the first connecting member 10 and the second connecting member 11 cannot be separated accidentally. Only when the limiting assembly 14 is in the non-limiting state, the operating member 131 can slide freely along the third direction, so that the first connecting member 10 and the second connecting member 11 can be detached and separated. The limiting assembly 14 is utilized to enable the disassembly and separation of the first connecting piece 10 and the second connecting piece 11 to be more controllable.

Alternatively, referring to fig. 3 to 5, the limiting assembly 14 includes a limiting member 141, and the limiting member 141 is sleeved on the operating member 131;

when the limiting member 141 is in the limiting state, the limiting member 141 can prevent the operating member 131 from sliding along the third direction;

when the limiting member 141 is in the non-limiting state, the operating member 131 can freely slide in the third direction.

Specifically, as shown in fig. 3 to 5, in one embodiment, a stopper 141 provided on the operating member 131 may be used to limit the operating member 131, and the stopper 141 may rotate around the axis of the operating member 131. When the rotation limiting member 141 is in the limiting state, the limiting member 141 prevents the operating member 131 from being accidentally touched by blocking the operating member 131 from sliding along the third direction, so that the engaging member 12 and the first connecting member 10 maintain the engaged state. When the rotation limiting member 141 is in the non-limiting state, the limiting member 141 does not limit the movement of the operating member 131, and the operating member 131 can slide freely along the third direction to drive the engaging member 12 to engage with or disengage from the first connecting member 10.

As shown in fig. 3 to 7, in an embodiment, the limiting element 141 may include a sleeve 1411 and a lever 1412, where the sleeve 1411 is fixedly connected to the lever 1412, and the sleeve 1411 is sleeved on the operating element 131. When a user applies force to the shift lever 1412, the sleeve 1411 can be driven to move synchronously, and the setting of the shift lever 1412 can increase the rotation arm of the sleeve 1411, so that the user can rotate the limiting element 141 easily with smaller force. The sleeve 1411 is disposed at an opening position of the shaft hole 113, and the sleeve 1411 is sleeved on the operating member 131, wherein a groove 14111 is formed on an inner wall of the sleeve 1411, and a flange 1311 is formed on an outer wall of the operating member 131. Thus, when a user applies force to the lever 1412, the stopper 141 is urged to rotate about the axis of the operating member 131 at the opening of the shaft hole 113.

When the stopper 141 is in the stopper state after rotation, the projection of the flange 1311 is staggered with the projection of the groove 14111 in the axial direction of the operation member 131. At this time, the flange 1311 is dislocated from the groove 14111, and cannot be normally slid into the groove, so that the pressing of the operating member 131 is blocked, and thus, the axial movement of the operating member 131 is restricted and locked, and erroneous touching pressing can be prevented.

Once in the unqualified state after the rotation of the stopper 141, the projection of the flange 1311 substantially coincides with the projection of the groove 14111 in the axial direction of the operation member 131. At this time, the flange 1311 is slidably fitted into the groove 14111 by an external force pressing, and thus the axial movement of the operating member 131 is unlocked, and the engaging member 12 is movable therewith after the pressing.

Thus, the recess 14111 on the inner wall of the sleeve 1411 and the flange 1311 on the outer wall of the operating member 131 can be used in cooperation with each other at different positions to effectively prevent the operating member 131 from being pressed by a false touch, and the operation is simple.

Alternatively, referring to fig. 5 and 6, the inner wall of the sleeve 1411 is provided with two grooves 14111 opposite to each other, and the outer wall of the operating member 131 is provided with two flanges 1311 opposite to each other.

Specifically, as shown in fig. 5 and 6, in one embodiment, two grooves 14111 may be disposed opposite to each other on the inner wall of the sleeve 1411, and the two grooves 14111 are symmetrically distributed. Accordingly, the outer wall of the operating member 131 may be symmetrically provided with two flanges 1311. In this way, no matter when the limiting member 141 is in the above-mentioned limiting state or the non-limiting state, the force applied to the operating member 131 is more balanced, and the axial pressing is not easy to be blocked.

Alternatively, referring to fig. 6, the sleeve 1411 and the lever 1412 are integrally injection molded, and the lever 1412 is coupled to the outer wall of the sleeve 1411 in the radial direction of the sleeve 1411.

Specifically, as shown in fig. 6, in one embodiment, the sleeve 1411 and the lever 1412 may be injection molded as one body by an injection molding process using a mold, and the assembly process may be reduced. The lever 1412 is coupled to the outer wall of the sleeve 1411 in the radial direction of the sleeve 1411 to increase the rotational moment arm of the sleeve 1411 and thereby save more effort in rotating the sleeve 1411.

Optionally, referring to fig. 8, the limiting assembly 14 further includes a positioning member 142 for connecting the limiting member 141 to the second connecting member 11.

Specifically, as shown in fig. 8, in one embodiment, a positioning member 142 may be used to connect the limiting member 141 to the second connecting member 11, so that the limiting member 141 rotates to a limited state or an unlimited state on the second connecting member 11. For example, the stopper 141 may be fixed by a pin to prevent it from falling off the second connector 11.

As shown in fig. 8, in the embodiment, in order to prevent the sleeve 1411 from falling out of the opening position of the shaft hole 113, a first positioning hole 14112 is provided on the outer wall of the sleeve 1411, and a second positioning hole 115 is provided on the second connection member 11, the second positioning hole 115 being in communication with the shaft hole 113. Thus, when the sleeve 1411 is disposed at the opening position of the shaft hole 113, and the sleeve 1411 is sleeved on the operating member 131, a portion of the sleeve 1411 also extends into the shaft hole 113, and the positioning member 142 is inserted into the second positioning hole 115 and passes through the first positioning hole 14112, so that the sleeve 1411 can be prevented from slipping in the axial direction.

Optionally, referring to fig. 9, the quick-release connection assembly further includes a self-locking assembly 15, and the self-locking assembly 15 is fixedly connected with the limiting assembly 14;

when the self-locking assembly 15 is in a self-locking state, the self-locking assembly 15 prevents the sleeve 1411 from rotating, so that the limiting piece 141 is in a limiting state;

when the self-locking assembly 15 is in the non-self-locking state, the self-locking assembly 15 allows the rotation of the sleeve 1411 so that the stopper 141 is in the non-stopper state.

Specifically, as shown in fig. 9, in one embodiment, to further prevent the free movement of the limiting component 14 from causing the operating member 131 to be touched and pressed by mistake, a self-locking component 15 for preventing the free movement of the limiting component 14 may be further provided in the quick-release connection component. The self-locking assembly 15 is fixedly connected with the limiting assembly 14, and when the self-locking assembly 15 moves, the limiting assembly 14 can be driven to move synchronously with the self-locking assembly.

Under the condition that the self-locking assembly 15 is in the non-self-locking state, the self-locking assembly 15 allows the limiting assembly 14 to freely move, the sleeve 1411 can freely rotate, at this time, the limiting member 141 is in the non-limiting state, and the operating member 131 can freely move to drive the clamping member 12 to be clamped or separated from the first connecting member 10.

When the self-locking assembly 15 is in the self-locking state, the self-locking assembly 15 prevents the limiting assembly 14 from freely moving, the sleeve 1411 cannot rotate, at this time, the limiting member 141 is in the limiting state, the operating member 131 is blocked from freely moving, the operating member 131 is locked, and the engaging member 12 and the first connecting member 10 remain engaged. Therefore, the self-locking assembly 15 is matched with the limiting assembly 14 to realize a double false touch prevention design.

Optionally, referring to fig. 9, the self-locking assembly 15 includes a stop collar 151, an elastomer 152, and a torsion spring 153;

the limiting ring 151 and the torsion spring 153 are both sleeved on the operating member 131, one end of the torsion spring 152 is abutted against the second connecting member 11, and the other end of the torsion spring 152 is abutted against the limiting ring 151;

the limiting ring 151 and the torsion spring 153 are located between the sleeve 1411 and the second connecting piece 11, and the sleeve 1411 is fixedly connected with the limiting ring 151;

the deformation of the elastic body 152 is used to control the stop collar 151 to be in the self-locking state or the non-self-locking state.

Specifically, as shown in fig. 9, in one embodiment, the self-locking assembly 15 may include a limiting ring 151, an elastomer 152 and a torsion spring 153, where the limiting ring 151 is a sheet-shaped part, and the center is hollowed out. The elastic body 152 is connected with the limiting ring 151, and the deformation of the elastic body 152 is used for controlling the limiting ring 151 to be in a self-locking state or a non-self-locking state. The limiting ring 151 and the torsion spring 153 are both sleeved on the operating member 131, one end of the torsion spring 153 is abutted against the second connecting member 11, and the other end of the torsion spring 153 is abutted against the limiting ring 151. When the limiting ring 151 rotates, the two ends of the torsion spring 153 can be driven to rotate relatively, so as to generate a reset torsion.

The limiting ring 151 and the torsion spring 153 are located between the sleeve 1411 and the second connecting member 11, and the sleeve 1411 is fixedly connected with the limiting ring 151. The sleeve 1411 and the limiting ring 151 can be fixed together through a buckle and a clamping connection or a threaded connection, so that the sleeve 1411 can drive the limiting ring 151 to synchronously rotate when rotating.

Therefore, under the cooperation of the elastic body 152 and the torsion spring 153, the elastic body 152 can enable the limiting ring 151 to be in a self-locking state, and the torsion spring 153 can provide torsion for the limiting ring 151 to automatically restore to a non-self-locking state.

Thereby, the elastic body 152 is fixed, and the elastic body 152 is prevented from tipping when being deformed in a telescopic way.

When the elastic body 152 is ejected from the mounting seat 1512, the elastic body 152 can cooperate with the second connecting piece 11 to block the rotation of the limiting ring 151, so that the limiting ring 151 is in a self-locking state. When the elastic body 152 is retracted into the mounting seat 1512, the limiting ring 151 can rotate freely, and the limiting ring 151 is in a non-self-locking state.

Alternatively, referring to fig. 11, the outer wall of the second connector 11 is provided with a clamping groove 116 communicating with the accommodating portion 111;

the elastic body 152 is embedded in the clamping groove 116 when the elastic body 152 is ejected from the mounting seat 1512;

when the elastic body 152 is retracted into the mounting seat 1512, the elastic body 152 is disengaged from the card slot 116.

Specifically, as shown in fig. 11, in one embodiment, the outer wall of the second connecting member 11 is provided with a clamping groove 116 that is communicated with the accommodating portion 111, and when the elastic body 152 is separated from the clamping groove 116, under the torsion reset action of the torsion spring 153, the torsion spring 153 can drive the limiting ring 151 to rotate to a non-self-locking state, and at this time, the limiting member 141 synchronously rotates to a non-limiting state. When the limiting ring 151 rotates to a self-locking state, at this time, the mounting seat 1512 is aligned with the clamping groove 116, the elastic body 152 is automatically embedded in the clamping groove 116 under the action of elastic force, and at this position, the limiting ring 151 cannot rotate, and accordingly, the limiting piece 141 is in a limiting state at this time.

the reed and the torsion spring are both sleeved on the operation piece 131, one end of the torsion spring is abutted against the second connecting piece 11, and the other end of the torsion spring is abutted against the reed;

the reed and the torsion spring are positioned between the sleeve 1411 and the second connecting piece 11, and the sleeve is fixedly connected with the reed;

the spring leaf is in the self-locking state or the non-self-locking state due to the deformation of the elastic clamping structure.

Specifically, in one embodiment, the self-locking assembly 15 may include a reed and a torsion spring. The reed is a sheet-shaped part, the center of the reed is hollowed out, and an elastic clamping structure, such as a wavy strip-shaped clamping structure, is arranged in a radial extending mode. The reed and the torsion spring are both sleeved on the operation piece 131, one end of the torsion spring is abutted with the second connecting piece 11, and the other end of the torsion spring is abutted with the reed. When the reed rotates, the two ends of the torsion spring can be driven to rotate relatively, and a reset torsion force is generated.

The reed and torsion spring are located between the sleeve 1411 and the second connector 11, the sleeve 1411 being fixedly connected to the reed. The sleeve 1411 and the reed can be fixed together through a buckle and a clamping connection or a threaded connection, so that when the sleeve 1411 rotates, the reed can be driven to synchronously rotate. The elastic clamping structure has two different position shapes before and after deformation, and can control the reed to be in a self-locking state or a non-self-locking state.

in the case that the elastic clamping structure is embedded in the clamping groove 116, the reed is in the self-locking state;

in the case that the elastic clamping structure is separated from the clamping groove 116, the reed is in the non-self-locking state.

Specifically, as shown in fig. 11, in one embodiment, the outer wall of the second connecting member 11 is provided with a clamping groove 116 that is communicated with the accommodating portion 111, and when the elastic clamping structure is separated from the clamping groove 116, the torsion spring can drive the reed to rotate to a non-self-locking state under the torsion reset action of the torsion spring, and at this time, the limiting member 141 synchronously rotates to a non-limiting state. When the reed rotates to a self-locking state, at this time, the elastic clamping structure is aligned with the clamping groove 116, the elastic clamping structure is automatically embedded in the clamping groove 116 under the action of elastic force, and at the position, the reed cannot rotate, and accordingly, the limiting piece 141 is in a limiting state at this time.

Specifically, as shown in fig. 12 and 13, in one embodiment, in order to improve the convenience of operation, a stopper 1011 that is matched with the clamping groove 116 may be further disposed on the clamping portion 101, after the first connector 10 is in plug-in matching with the second connector 11, the clamping portion 101 is embedded in the accommodating portion 111, meanwhile, the stopper 1011 is located in the clamping groove 116, and the self-locking assembly 15 may be pushed by the stopper 1011 to disengage from the clamping groove 116, when the self-locking assembly 15 is disengaged from the clamping groove 116, under the action of the torsion spring 153, the self-locking assembly 15 automatically moves to a non-self-locking state, and accordingly, the sleeve 1411 is in a limiting state, and the movement of the operating member 131 is locked. It can be understood that once the first connector 10 is mated with the second connector 11, the operating member 131 will be automatically locked, if the first connector 10 is separated from the second connector 11, the sleeve 1411 needs to be rotated to the non-limiting state to unlock the operating member 131, then the operating member 131 is pressed to drive the engaging member 12 to move to release the first connector 10, and after the first connector 10 is separated from the second connector 11, the clamping slot 116 is emptied to accommodate the elastic body 152 or the elastic clamping structure.
