Most of the existing unmanned aerial vehicles have long horn, and in order to prevent the horn from being too long and occupying large space, the horn can be folded under normal conditions. In the folding aircraft of most horn, expand and fixed in-process to the horn, need fix the horn, and to the fixed of horn, the operation degree of difficulty is great under the normal conditions, is difficult to alone accomplish, has increaseed unmanned vehicles's the use degree of difficulty, has reduced user's use and has experienced.

In view of the above, please refer to fig. 1, which provides a locking assembly 10 and an unmanned aerial vehicle (not shown) using the locking assembly 10 of the present application, so as to solve the technical problem of the prior art that the difficulty of fixing the horn 11 is high.

In an embodiment of the present application, referring to fig. 1 and fig. 2, the locking assembly 10 includes a first clamping member 100, a second clamping member 200, a locking member 300, a pushing member 400, and a limiting structure 500. Wherein one end of the first clamping member 100 is rotatably coupled to one end of the second clamping member 200; the locking member 300 is rotatably coupled to the other end of the first clamping member 100, and the locking member 300 is detachably engaged with the second clamping member 200. Under the condition that the locking fastener 300 is clamped in the second clamping member 200, a clamping space 101 is formed between the first clamping member 100 and the second clamping member 200, and the clamping space 101 is used for clamping the horn 11 of the unmanned aerial vehicle, so that the horn 11 of the unmanned aerial vehicle is kept in a spread state. In addition, the second clamping member 200 is provided with a pushing wall 210; the position-limiting structure 500 is connected to the locking element 300, and the pushing element 400 is rotatably connected to the position-limiting structure 500. The limiting structure 500 is used for limiting the rotation angle of the pushing member 400, so that the pushing member 400 forms an acute angle with the pushing wall 210 when contacting the pushing wall 210. The locking member 300 is used for driving the pushing member 400 in the process of being clamped with the second clamping member 200, so that the pushing member 400 pushes against the pushing wall 210, and the first clamping member 100 and the second clamping member 200 are tensioned under the combined action of the locking member 300 and the pushing member 400.

In other words, the locking assembly 10 clamps the arm 11 generally as follows, the first clamping member 100 and the second clamping member 200 are rotated relatively to make the first clamping member 100 and the second clamping member 200 respectively attached to two sides of the arm 11, and then the locking member 300 is rotated relatively to the first clamping member 100 to make the locking member 300 rotate toward the second clamping member 200, so as to facilitate the locking member 300 to be clamped to the second clamping member 200. In the process of clamping the locking member 300 to the second clamping member 200, the locking member 300 drives the pushing member 400 to move toward the second clamping member 200, and the pushing member 400 is pushed against the pushing wall 210. Subsequently, in the process of clamping the locking member 300 to the second clamping member 200, the locking member 300 gets closer to the second clamping member 200, so that the pushing wall 210 pushes the second clamping member 200 to move toward the first clamping member 100, thereby making it possible to tie the first clamping member 100 and the second clamping member 200 under the combined action of the locking member 300 and the pushing member 400 under the condition that the locking member 300 and the second clamping member 200 are completely clamped, thereby completing the purpose of clamping the mechanical arm 11 by the locking assembly 10, and making the mechanical arm 11 maintain a stable unfolded state.

As described above, in the process of clamping the locking member 300 to the second clamping member 200, the locking member 300 drives the pushing member 400 to move, so that the pushing member 400 contacts the pushing wall 210 on the second clamping member 200; due to the arrangement of the limiting structure 500, the rotation angle of the pushing piece 400 relative to the lock catch piece 300 is limited, so that when the pushing piece 400 contacts with the pushing wall 210, the pushing piece 400 and the pushing wall 210 form an acute angle, and therefore, in the process of clamping the lock catch piece 300 on the second clamping piece 200, the situation that the lock catch piece 300 cannot move close to the second clamping piece 200 due to the fact that the pushing piece 400 is perpendicular to the pushing wall 210 can be prevented. In other words, the acute angle is formed between the pushing wall 210 and the pushing member 400, so that the pushing member 400 can be conveniently rotated in the process that the locking member 300 moves close to the second clamping member 200, and the purpose of locking the locking member 300 to the second clamping member 200 can be easily achieved. When the locking member 300 is completely engaged with the second clamping member 200, the first clamping member 100 and the second clamping member 200 can be pulled tightly under the combined action of the locking member 300 and the pushing member 400. Therefore, the utility model provides a lock solid subassembly 10 can prevent to appear in the operation process and push away the condition that piece 400 perpendicular to top pushed wall 210 and influence the assembly to reach and improve among the prior art to the fixed high technical problem of the degree of difficulty of horn 11.

It is noted that in some embodiments of the present application, the ejection wall 210 is tilted to a side away from the clamping space 101 to form a slot 211 having an opening. The pushing member 400 is clamped in the slot 211 from the opening when the locking member 300 is clamped in the slot, and is limited by the pushing wall 210 to form self-locking when the locking member 300 and the second clamping member 200 are clamped. In other words, when the locking member 300 drives the pushing member 400 to move close to the pushing wall 210, the pushing member 400 is moved to the opening of the groove 211 and contacts the pushing wall 210. At this time, since an acute angle is formed between the pushing wall 210 and the pushing part 400, the pushing part 400 slides along the pushing wall 210 to slide into the groove 211 from the opening in the process that the locking member 300 moves close to the second clamping member 200; meanwhile, the pushing element 400 rotates relative to the locking element 300 and moves away from the limiting structure 500. In the process that the locking member 300 continues to move to be clamped in the second clamping member 200, the pushing member 400 slides into the inner wall of the slot 211 and pushes against the bottom wall of the slot 211, so that a pushing relationship is formed between the pushing member 400 and the pushing wall 210. And the first clamping member 100 and the second clamping member 200 can be tightened under the combined action of the locking member 300 and the pushing member 400 during the process that the locking member 300 continues to move close to the second clamping member 200 to complete the clamping with the second clamping member 200.

In some embodiments of the present application, the pushing element 400 is substantially rod-shaped, and when the pushing element 400 contacts the pushing wall 210, the end of the pushing element 400 contacts the pushing wall 210. The pressing member 400 and the pushing wall 210 form an acute angle, which means that the axis of the pressing member 400 and the tangent line of the pushing wall 210 contacting the pressing member 400 form an acute angle.

It should be noted that, as shown in fig. 3, the pushing wall 210 can be divided into a sliding section 212 and a holding section 213, the sliding section 212 extends along a substantially straight line, and the holding section 213 is curved to form the slot 211. Under the condition that the abutting part 400 abuts against the limiting structure 500 and contacts with the abutting wall 210, the end part of the abutting part 400 abuts against the sliding section 212, and an acute angle is formed between the abutting part 400 and the sliding section 212, so that when the locking fastener 300 continuously approaches to the second clamping member 200 to be clamped on the second clamping member 200, the abutting part 400 slides on the sliding section 212 to slide into the abutting section 213 and abut against the abutting section 213; under the condition that the locking piece 300 is completely clamped with the second clamping piece 200, the abutting piece 400 is approximately parallel to the sliding section 212, and the first clamping piece 100 and the second clamping piece 200 are tensioned in a manner of abutting against the abutting section 213. Of course, the pressing member 400 and the pressing wall 210 form an acute angle, which means that the pressing member 400 and the sliding section 212 form an acute angle. The acute angle can be represented by angle α in fig. 3, where the dashed line is the axis of the push-against 400.

Optionally, referring to fig. 2 and 4 in combination, in some embodiments of the present application, the position-limiting structure 500 includes a pivoting portion 510 and a position-limiting portion 520. The pivoting portion 510 is connected to the locking element 300, and the limiting portion 520 is connected to the pivoting portion 510. The pushing element 400 is rotatably connected to the pivot portion 510, in other words, the pushing element 400 is rotatably connected to the pivot portion 510 to rotate relative to the locking element 300. The limiting portion 520 is at least partially disposed on a side of the pivot portion 510 away from the locking element 300 for abutting against the pushing element 400, so as to limit the rotation angle of the limiting portion 520. In other words, the pushing element 400 can rotate between the limiting portion 520 and the locking element 300, so that the rotation stroke of the pushing element 400 can be limited by the limiting portion 520 and the locking element 300.

It should be noted that the limiting portion 520 can limit the rotation angle of the pushing element 400 relative to the locking element 300. Based on the state of the pushing element 400 contacting the locking element 300, the pushing element 400 rotates relative to the locking element 300 until the pushing element abuts against the limiting portion 520, which is the maximum angle of rotation of the pushing element 400 relative to the locking element 300. When the pushing member 400 is pushed against the limiting portion 520, the pushing member 400 contacts the pushing wall 210 to form an acute angle, and based on this, when there is a gap between the pushing member 400 and the limiting portion 520, the included angle between the pushing member 400 and the pushing wall 210 is reduced, that is, an acute angle is also formed between the pushing member 400 and the pushing wall 210. In other words, when the locking member 300 approaches the second clamping member 200, the pushing member 400 can rotate to push against the limiting portion 520, and at this time, the pushing member 400 can contact the pushing wall 210 and form an acute angle with the pushing wall 210. As the locking member 300 approaches the second clamping member 200 to clamp the second clamping member 200, the pushing member 400 slides along the pushing wall 210 to slide into the groove 211 from the opening until being pushed against the bottom of the groove 211; in the process, the pushing element 400 rotates relative to the locking element 300 and moves away from the limiting structure 500 until the locking element 300 and the second clamping element 200 are completely clamped, and the pushing element 400 is limited by the pushing wall 210 to form self-locking.

In addition, the limiting portion 520 can prevent the pushing member 400 from rotating too much relative to the locking member 300, so that the pushing member 400 cannot push the pushing wall 210. Therefore, by the limiting function of the limiting portion 520 on the pushing member 400, an operator can easily rotate the locking member 300 to enable the pushing member 400 to be pushed against the pushing wall 210, and the pushing member 400 and the pushing wall 210 form an acute angle, so that the locking member 300 can be easily clamped with the second clamping member 200, and the purpose of tightening the first clamping member 100 and the second clamping member 200 by the combined action of the locking member 300 and the pushing member 400 is achieved.

Optionally, in some embodiments of the present application, there are two pivoting portions 510, the two pivoting portions 510 are disposed at an interval, and the pushing element 400 is rotatably connected to both pivoting portions 510 and located between the two pivoting portions 510. The position-limiting portion 520 is disposed between the two pivoting portions 510. By arranging the pushing element 400 between the two pivoting portions 510 and rotationally connecting the pushing element 400 with the two pivoting portions 510 at the same time, the stability of the rotational fit between the pushing element 400 and the pivoting portions 510 can be improved, and the pushing element 400 can be ensured to rotate along a designated path. Therefore, the position-limiting portion 520 is disposed between the two pivoting portions 510, so that the position-limiting portion 520 can effectively provide a position-limiting effect for the pushing element 400.

It should be understood that in other embodiments of the present application, one of the pivoting portions 510 may be eliminated, in other words, only one pivoting portion 510 may be provided. It is only necessary to ensure that the limiting portion 520 is located on the rotation path of the pushing member 400 and provide a limiting effect on the pushing member 400, so that the pushing member 400 contacts with the pushing wall 210 to form an acute angle under the limiting effect of the limiting portion 520.

In addition, the limiting part 520 is connected with both pivoting parts 510, and together form a sliding slot 530; the pushing component 400 is movably disposed in the sliding groove 530. The two pivoting portions 510 form side walls of the sliding slot 530, the limiting portion 520 forms an end of the sliding slot 530, and the other end of the sliding slot 530 is limited by the locking member 300. The pushing element 400 can slide in the sliding groove 530 and is abutted against the limiting portion 520 or the locking element 300, thereby limiting the rotation stroke of the pushing element 400.

It should be understood that in other embodiments of the present application, the position-limiting portion 520 may also be connected to only one of the pivoting portions 510, and only the position-limiting portion 520 is located between the two pivoting portions 510 to provide a position-limiting effect for the pushing element 400. Of course, in the case that the position-limiting portion 520 is connected to only one of the pivoting portions 510, a gap is formed between the position-limiting portion 520 and the other pivoting portion 510, and the gap is communicated with the sliding groove 530.

Optionally, in some embodiments of the present application, the pivoting portion 510 is triangular with one corner being a rounded corner 513, and the rounded corner 513 on the pivoting portion 510 is located on a side of the pivoting portion 510 away from the locking element 300; in other words, the pivot portion 510 can be regarded as having a first side 511 connected to the fastener 300 and two other second sides 512, and a rounded corner 513 is formed corresponding to the first side 511. In addition, the limiting portion 520 includes a straight section 521 and an arc-shaped section 523, the straight section 521 is connected to one of the second sides 512, and the arc-shaped section 523 is connected to a position of the rounded corner 513 of the pivot portion 510, so that the limiting function is provided to the pushing element 400 through the arc-shaped section 523. It should be understood that in other embodiments of the present application, the straight segment 521 of the limiting portion 520 may be eliminated, and only the arc segment 523 provides a limiting effect to the pushing member 400.

In order to adapt the shape of the sliding groove 530 to the abutting piece 400, a groove body with an arc-shaped side wall is formed on the arc-shaped section 523 of the limiting portion 520, and the groove body forms an end portion of the sliding groove 530, so that the abutting piece 400 can be accommodated in the groove body with the arc-shaped side wall when moving to abut against the arc-shaped section 523, and the abutting stability of the limiting portion 520 and the abutting piece 400 is improved. Of course, in other embodiments, the groove body with the arc-shaped side wall may be omitted.

Optionally, in some embodiments of the present application, the position-limiting portion 520 and the two pivoting portions 510 are integrally formed. The position-limiting portion 520 and the pivot portion 510 can be directly molded by injection molding to form a whole. In the process of connecting the limiting structure 500 and the pushing-against member 400 to the locking member 300, the pushing-against member 400 can be assembled to the pivoting portion 510 first, and then the pivoting portion 510 is assembled to the locking member 300, thereby completing the assembly of the limiting structure 500 and the pushing-against member 400. Of course, in other embodiments, one of the pivoting portion 510 and the limiting portion 520 may be a split type. For example, in the case that the position-limiting portion 520 is connected to only one of the pivoting portions 510, the position-limiting portion 520 and the other pivoting portion 510 are separately formed, and therefore, the integrally formed position-limiting portion 520 and one of the pivoting portions 510 and the separately formed pivoting portions 510 can be integrally formed with the locking member 300; the other one can be detachably assembled with the locking member 300, thereby facilitating the coupling and matching of the pivoting portion 510 and the pushing member 400.

In some embodiments of the present application, please refer to fig. 5 and 6 in combination, in order to further improve the assembling convenience of the locking assembly 10, optionally, the locking assembly 10 further includes an elastic member 600. The elastic element 600 is connected to the locking element 300, and the elastic element 600 is used for applying an acting force to the pushing element 400, so that the pushing element 400 is pushed against the limiting structure 500. In other words, the elastic element 600 can provide a force to the pushing element 400, so that the pushing element 400 is kept in a state of being abutted against the limiting structure 500. Therefore, the pushing member 400 can be conveniently pushed against the sliding section 212 of the pushing wall 210, so that an operator can conveniently judge the position of the pushing member 400, and the assembly convenience of the locking assembly 10 is improved.

In addition, in the process of clamping the locking element 300 to the second clamping element 200, the locking element 300 drives the pushing element 400 to rotate, and the elastic element 600 is compressed in the process of rotating the pushing element 400 relative to the locking element 300 until the locking element 300 is clamped to the second clamping element 200. In some embodiments of the present application, in order to facilitate the engagement of the locking element 300, the elastic element 600 may be configured to provide a smaller acting force, and the acting force only needs to satisfy the requirement that the pushing element 400 automatically moves to abut against the limiting structure 500, so as to prevent the locking element 300 from being difficult to engage due to an excessive elastic force generated by the elastic element 600.

Of course, in other embodiments of the present application, the elastic member 600 may be eliminated.

It should be noted that, since the elastic element 600 is compressed by the pushing element 400 under the condition that the locking element 300 is clamped to the second clamping element 200, in other words, the elastic element 600 also applies an elastic force to the pushing element 400. When the locking assembly 10 is removed, the elastic force of the elastic member 600 acting on the pushing member 400 can assist the pushing member 400 to push out the groove 211 formed by the pushing wall 210, so as to provide an auxiliary force for releasing the locking member 300 from the second clamping member 200, thereby facilitating the release of the locking member 300.

Optionally, in some embodiments of the present application, the elastic member 600 includes an elastic portion 610 and an abutting portion 620; one end of the elastic portion 610 is connected to the locking element 300, the abutting portion 620 is disposed at the other end of the elastic portion 610, and the abutting portion 620 abuts against the abutting element 400. In order to ensure that the supporting portion 620 can stably support against the pushing wall 210, the elastic portion 610 is curved to form an arc shape and protrudes toward a side away from the pushing member 400. In other words, the end of the elastic portion 610 where the abutting portion 620 is disposed is bent toward the abutting member 400, thereby ensuring that the abutting portion 620 can stably abut against the abutting member 400.

It should be understood that in other embodiments of the present application, the elastic portion 610 may be provided in other shapes. For example, a state extending along a straight line; for example, the wave-like state.

Optionally, in some embodiments of the present application, in order to prevent the supporting portion 620 from damaging the supporting member 400, the supporting portion 620 is curved to be an arc, and the convex arc surface of the supporting portion 620 supports against the supporting member 400. Therefore, the damage to the abutting part 400 can be prevented, the abutting part 620 can slide smoothly relative to the abutting part 400, and the elastic part 600 is prevented from being damaged due to the fact that the abutting part 620 forms a pit on the abutting part 400 and is clamped in the pit.

Of course, in some embodiments of the present application, the resilient member 600 is detachably connected to the latch member 300 by a screw connection, but the resilient member 600 may be connected to the latch member 300 by other methods, such as clamping or welding. In addition, in other embodiments of the present application, a torsion spring may be disposed at a connection position between the pivot portion 510 and the abutting member 400, so that the arrangement manner of the elastic portion 610 and the abutting portion 620 may be eliminated, and the abutting member 400 may be maintained in the state of abutting on the limiting structure 500 through the torsion spring.

In summary, in the locking assembly 10 provided in the embodiment of the present application, in the process of clamping the locking member 300 to the second clamping member 200, the locking member 300 drives the pushing member 400 to move, so that the pushing member 400 contacts the pushing wall 210 on the second clamping member 200; due to the arrangement of the limiting structure 500, the rotation angle of the pushing member 400 relative to the locking member 300 is limited, so that when the pushing member 400 contacts with the pushing wall 210, the pushing member 400 and the pushing wall 210 form an acute angle, and therefore, in the process of clamping the locking member 300 to the second clamping member 200, the situation that the locking member 300 cannot move close to the second clamping member 200 due to the fact that the pushing member 400 is perpendicular to the pushing wall 210 can be prevented. In other words, the acute angle is formed between the pushing wall 210 and the pushing member 400, so that the pushing member 400 can be conveniently rotated in the process that the locking member 300 moves close to the second clamping member 200, and the purpose of locking the locking member 300 to the second clamping member 200 can be easily achieved. When the locking member 300 is completely engaged with the second clamping member 200, the first clamping member 100 and the second clamping member 200 can be pulled tightly under the combined action of the locking member 300 and the pushing member 400. Therefore, the utility model provides a lock solid subassembly 10 can prevent to appear in the operation process and push away the condition that piece 400 perpendicular to top pushed wall 210 and influence the assembly to reach and improve among the prior art to the fixed high technical problem of the degree of difficulty of horn 11. In addition, through set up elastic component 600 on limit structure 500, can ensure to support and push away piece 400 and support and hold on limit structure 500, make things convenient for lock catch piece 300 joint on second clamping piece 200, make things convenient for lock catch piece 300 to pull down from second clamping piece 200 simultaneously, improve the convenience.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
